A Comparative Study on Food Habits and Nutrient Intakes among High School Students with Different Obesity Indexes Residing in Seoul and Kyunggi-do: Myoung Sook Lee, Chung Ja Sung, Mi Kyung Sung, Mi Kyeong Choi, Yoon Shin Lee, Kyung Ok Cho; Korean J Community Nutr 2000;5(2):141-151. Published online July 31, 2000

Abstract PDF: The purpose of this study was to compare food habits and nutrient intakes among high school students with different obesity indexes who are residing in Seoul and Kyunggi-do. a total of 533 subjects were assigned to one of the following groups based on BMI : underweight, normal-weight and overweight. Food habits and nutrient intakes were evaluated based on questionnaires and 24hr-dietary record. The results were as follows. There was no significant differences in the general environmental characteristics of subjects with different BMI. However, the father's BMI was significantly higher in overweight female students compared to underweight or normal weight subjects. The menarch age was significantly decreased as the obesity increased. The self-satisfaction score for physical type was decreased as the BMI increased. The overweight group skipped dinner more frequently the other groups among male students. There was no significant difference in the scores of nutrition knowledge, nutritional attitude, and self -satisfaction of subjects with different BMI. The nutrient intakes of overweight group were the lowest among the three groups. In conclusion, obesity among female students may be related to family member's obesity. Also overweight students tend to have lower self satisfaction for their body image and undesirable food habits. Therefore, proper nutrition education is required to maintain desirable food habits for overweight students.

A Study on the Relations among Zinc Copper Metabolism, Blood Glucose, Insulin and Serum Lipids in Normal Adult Women: Seng Lue Kim, Chung Ja Sung, Mi Hyun Kim; Korean J Community Nutr 2000;5(2):152-160. Published online July 31, 2000

Abstract PDF: The purpose of this study was to investigate zinc and copper metabolism and risk factors of chronic diseases in 20 normal adults women. The daily intake, excretions in urine and feces, and serum levels of zinc and copper were determined by 24-hr food records and chemical analysis. The results were summarized as follows. mean age, body weight and BMI were 22.88 years, 54.65 kg and 21.28 kg/m2 respectively. Mean daily intakes of energy and protein were 1578.84 kcal(79% of RDA) and 52.05g (87% of RDA). The zinc and copper intake, excrestion in urine and feces were 7093.23 microgram(59% of RDA/2093.87 microgram, 203.50 microgram/39.87 microgram and 3416.41 microgram/857.62 microgram, respectively. The serum levels of fasting glucose, insulin, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglyceride, zinc and copper were 76.60 mg/dl, 15.66IU/dl, 160.30 mg/dl, 50.95 mg/dl, 89.80 mg/dl, 89.79 mg/dl, 95.65 microgram/dl and 73.28 microgram/dl respectively. Dietary ratio of Zn to Cu was shown to have significant positive correlations with serum insulin, total cholesterol, LDL-cholesterol. The urinary ratio of Zn to Cu was shown to have significant positive correlations with triglyceride. The serum copper level was shown to have significant negative correlations with serum total cholesterol and LDL-cholesterol. In summary, Zn consumption of adult women in their normal diet does not meet the Zn requirement for Koreans. Also, intakes of Zn and Cu may effect the glucose metabolism and cardiovascular diseases. Therefore, to increase the Zn intake and to maintain an appropriate intake ratio of Zn to Cu, nutrition education needs to be implemented.

The Effects of Smoking and Alcohol Drinking on Nutritional Status and Eating Habits in Adult Males: Chung Shil Kwak, Joung Won Lee, Wha Jin Hyun; Korean J Community Nutr 2000;5(2):161-171. Published online July 31, 2000

Abstract PDF: The purpose of this study was to investigate the effects of smoking and/or alcohol drinking on the nutrient intake, nutritional status, and eating habits of adult males. The subjects were 157 male adults aged 20-49 living in Daejon. Interviews with questionaire on smoking and alcohol drinking habits and eating habits, anthropometric measurement, biochemical blood test, and dietary assessment by one-day 24 hour recall and two-day diet record were carried out. The subjects were divided into four groups : control (non-smoking and non-drinking), drinking only, smoking only, and the both(drinking and smoking). The average numbers of smoked cigarettes were 17.8/d and 19.1/d in the smoking only group and the both group, respectively. The frequency of alcohol drinking was 8.3 times/month and 11.6 times/month in the drinking only group and the both group, respectively. Height was significantly higher(P 0.05) in the drinking only group than in the none and smoking only groups, while the other anthropometric indices were not different among the four groups. There were positive correlations between smoking and drinking or coffee intake. Alcohol drinking increased eating-out frequency and the intakes of energy, protein, dietary fiber, vitamin A, B1, B/sub 6/, Fe and P, while smoking decreased snack frequency and intakes of energy, protein and vitamin B/sub 6/. Blood pressure was not changed in the smoking only and drinking only groups compared to the none group, while systolic blood pressure was elevated in both group(P 0.05). Alcohol drinking significantly elevated(P 0.05) serum total cholesterol and LDL-cholestrol level, while smoking did not change the serum lipid and cholesterol levels. Hemoglobin nd MCHC levels were significantly elevated(P 0.05) by smoking. From these data, it is suggested that both smoking and drinking have influence on some eating habits and nutrient intakes, and especially alcohol drinking can induce hypercholesterolemia.

A Long Term Observation of Total Cholesterol, Blood Pressure, BMI and Blood Glucose Concerned with Dietary Intake: In Sook Kim, Eun A Seo; Korean J Community Nutr 2000;5(2):172-184. Published online July 31, 2000

Abstract PDF: To establish a basic cohort which can survey the nutrient and food intake related to the health status of the middle and old-aged vertically, a longitudinal survey of 110 adults over forty years old was conducted three times in Chon-ju city over 5 years (1994-1999), and the influences of health status by changes in their nutrient and food intake were examined in this study. The results were as follows ; The number of subjects was 110(43 man, 67 women), 10.0% in their forties, 28.2% in their fifties, 45.4% in their sixties 6.4% over seventy, and their average age was 61.4. There were decrease of height about 1 cm, increase of body fat % and few changes of BMI during the testing period. As the subjects were aging, the percentage of anemia increased, but averages of blood pressure and blood glucose(men : 91.8 mg/dl, women : 90.3 mg/dl) were constant. Total cholesterol increased from 196.7 mg/dl to 212.6 mg/dl(P 0.05) over five years, and the numerical values for women were higher than that of men. In many cases, lack of nutrient intake was shown, as compared with the Recommended Dietary allowance(RDA) especially calcium and vitamin A(71.7%, 64.9% of RDA). Grains intake showed a tendency to decrease(P 0.01). On the contrary, fruit intake showed a tendency to increase(P 0.001). On whole meal, plant foods were 85.1% and animal foods were 14.9%. As dietary factors influencing health status were investigated, blood glucose was influenced by vitamin B2, potatoes and triglyceride, DBP and SBP were affected by vitamin B1, vitamin C, legumes, fishes, triglyceride and age. Total cholesterol was under the influence of triglyceride, milk, seeds and fat. BMI was influenced by iron, SBP, animal food, and age.

Follow-up Study of Health-Related Habits and Health Status of Middle-Aged Men and Women in Chonju: Mee Sook Lee, Mee Kyung Woo, In Sook Kim; Korean J Community Nutr 2000;5(2):185-192. Published online July 31, 2000

Abstract PDF: As the percentage of the elderly in the population increases, research to identify the nutritional and health status of the elderly, to understand the factors influencing on them, and to delay aging have been done actively. It is necessary for these studies to be longitudinal. This study was carried out to assess the change of health-related habits such as dietary behaviors and smoking, alcohol drinking and exercising habit, and health status between previous study(1991/1994) and post study(1998) for middle-aged men and women living in Chonju. For the present study, the data of 63 pairs(23 men and 40 women) were analyzed. They were 11 men and 12 women followed up from 82 men and 100 women surveyed in 1994. Mean ages in the 1991/4 and 1998 studies were 53.6y(range 42-63y) and 59.0y(range 46-72y) respectively. The survey was conducted with interview using a questionnaire including dietary behaviors and health-related habits, and anthropometric measurement and blood test for analyzing biochemical indices in 1991/4 and 1998. To understand these changes over time, chi2-statistics, t-test and paired t-test were analyzed with an SAS package program. As people age, there were significantly decreases in the proportions to eat lightly salted foods and drink alcohol. Significant longitudinal increases in triceps skin fold thickness, gamma-GPT and HDL-cholesterol and significant decrease in hemoglobin value were noted over time in both men and women. In addition a significant decrease in blood glucose level was noted over time in women. Weight, blood glucose and total cholesterol increased significantly with age in those had had breakfast regularly or those had not used more slat at the table in the past. From this study, were found out the subjects of this study had relatively desirable health-related habits. But as improper health-related habits are likely to result in inappropriate health status(eg, increase in WHR, triglyceride, total cholesterol and LDL-cholesterol), it is recommended that nutrition education in necessary as soon as possible to meet the health elderly.

The Experience and Intention of Health Food Use among Middle-aged Men in Urban Areas: Hwa Suk Song, Se Young Oh; Korean J Community Nutr 2000;5(2):193-200. Published online July 31, 2000

Abstract PDF: This study examined the experience and intention of health food use regarding the different type of health foods among 201 middle-aged Korean men form urban areas. Based upon the results of a prestudy, health foods were classified into 4 groups including Chinese medicine(CM), toner foods(TF), vitamin or mineral supplements(VMS), and other manufactured heath food supplements(MHFS). compared with the4 case of health food experience, the similar proportion of the subjects were intended to use CM( 70%) and MHFS( 40%), yet the smaller proportion of them had the intention for TF(46%) and VMS(52%). Our subjects mainly obtained information on CM and TF from social networks, such as families, relatives, friends and neighbors and VMS and MHFS from mass media. Expected effects of health food consumption were different by the type of health food. The most positive expected effects were found in CM, followed by VMS. However, there was weak evidence for the positive effects of the TF and MHFS. Upon the consumption of health foods, our subject appeared to expect to their body energy to increased and body functions to be improved in general. Multivariate analyses indicated the importance of expected effects of health food consumption and aging symptoms as determinants of future health food use. Experience was rarely associated with intention in health food use. This study suggests that educated middle-aged Korean men may have a rational attitude toward health food use. Regarding different attitudes and behavior toward the different type of health foods, further research should consider the nature of each type of health foods. The limitations of this study are also discussed.

The Nutritional Status and Intervention Effects of Multivitamin-Mineral Supplementation in Nursing-Home Residents in Korea: Wha Young Kim, Sho Young Ahn, Yo Suk Song; Korean J Community Nutr 2000;5(2):201-207. Published online July 31, 2000

Abstract PDF: This study was performed to assess the nutritional status of nursing home residents and to assess the effect of nutrition intervention. The subjects were 123 people aged over 60 years from 5 different nursing homes. The nutrition intervention study was carried out by supplementing their diet with multivitamin-minerals for 2 months. The mean intakes of most nutrients did not meet the RDA, Though the nutrient content of the menus provided by the facilities were satisfactory. Nutrients of which intakes fell below 75% of the RDA were protein, Ca, Fe, vitamin A vitamin B1, and vitamin B2. The BMIs of male and female subjects were 22.0 kg/m2 and 24.6 kg/m2 and the WHRs were 0.92 and 0.90, respectively. The percentage of subjects with hypertention (BP> or =140/90 mmHg) and with anemia(Hb< or =13 mg/100ml in men, Hb< or =12 mg/100ml in women) were 34.6% and 41.9%, respectively. The serum cncentrations of albumin, total protein, triglyceride, total cholesterol, HDL-cholesterol, and total lipid fell within normal ranges. However, 27.5% of the subjects showed a high serum cholesterol level of over 250 mg/100ml. The concentration of C3 was 81.2 mg/100ml, IgG, 1343 mg/100ml, and IL-2, 0.766 mg/ml. after 2 months of vitamin-mineral supplementation, the levels of blood glucose and total cholesterol were significantly decreased and triglyceride was significantly increased. The vitamin-mineral supplementation had no effect on the mean levels of vitamin A and E, IgG, IL2, and C3. However, the intervention resulted int he improvement of serum vitamin A and E levels when the subject's serum levels were low before the supplementation.

The Effects of Customer Expectations & Satisfaction on Customer Loyalty in Restaurants: Ilsan Yang, Seoyoung Shin, Hyeyoung Kim; Korean J Community Nutr 2000;5(2):225-235. Published online July 31, 2000

Abstract PDF: Service quality has become an important factor to meet customer satisfaction in the food service industry where competition is getting severe. Organizations are focused upon strengthening customer loyalty through customer satisfaction. Therefore, this study, taking customers as subjects, is intended to analyze factors affecting customer loyalty, on the basis of service quality satisfaction. In doing. so, the analysis has been done with 232 customers who are purchasing service from the food services industry, for general information, and service quality expectation, service quality satisfaction and overall satisfaction. The results of the study are as below. 1) From a factor analysis, the service quality expectation level of customer has been categorized into 4 factors, which are named General 'General management ', 'Food', 'Reliability' and 'Reputation'. 2) From the factor analysis, the service quality satisfaction level of customer has been categorized into 6 factors, which are named 'Employee attitude', 'Food', 'Reliability', 'Atmosphere', 'Reputation' and 'Price'. 3) After classifying customers into 3 groups according to two criteria-"will buy the service again" and "will suggest to others", a comparison has been done for the service quality expectation dimension of customers by each customer group. The result shows that the group having both the "will buy the service again" and "will buy the service again "and "will suggest to others" criteria, that is, with higher customer loyalty, tend to have higher point than other group in factors of 'Food', 'Reliability', 'Reputation'(p<.05). 4) As per the dimension of customer's service quality satisfaction level, factors like 'Employee attitude', 'Food', 'Reliability', 'Atmosphere', 'Reputation', and 'Price' have shown differences according to each loyalty group(P<.001). 5) Customers' overall satisfaction level according to each customer loyalty group has been found to be more important for the group having a higher loyalty level(p<.001) 6) From the discriminant analysis with employing judging variables, such as the customer's service quality expectation level, service quality satisfaction level and general satisfaction level, customer loyalty groups have been identified as accurately as 68.9% of the explanatory power.

Effect of the Service Providers' Perceived Service Quality on Customer Loyalty in Restaurants: Hyeyoung Kim, Ilsan Yang, Seoyoung Shin; Korean J Community Nutr 2000;5(2):236-242. Published online July 31, 2000

Abstract PDF: Due to the diversification of the food industry and its heightened competition, the marketing strategy to be required the most would be to improve competitiveness by enhancing customer loyalty as a resulting variable of customer satisfaction. Thus, this study, taking a food service provider as a subject, is to find factors and the scope of the perceived quality ; and to analyze how far the perceived service quality factor as such could explain customer's overall satisfaction and customer loyalty ; finally to provide basic data for establishing a customer satisfaction marketing strategy as related to customer loyalty. The results of the study are as below. 1) 25 factors of service quality perceived by a food service provider have been categorized into 8 independent dimensions through factor analysis. Each of them are named 'Employee attitude', 'Cleanliness', 'Reputation', 'Reliability', 'Food', 'Price', 'Convenience', 'Variety', all of which explain 64.3% of the service again quality perception level. 2) After classifying customers into 3 groups according to two criteria -"will buy the service again" and "will suggest it to others" and making a pair of service providers with each customer, each customer loyalty group compared the service quality perception factor of the food service provider. The result was that the group having both the "will buy the service again" and "will suggest to others" criteria, that is, with higher loyalty, tend to have higher points than other group s in the dimension of 'Employee attitude' and 'Cleanliness'(p<0.05), which means these two dimensions are closely related to customer loyalty. 3) From a regression analysis for the service quality perception level of the food service provider and overall satisfaction, it has been found that : the regression models are different for each group, that 'Employee attitude' seems to be related more closely to the group with higher loyalty(p<0.05); that the 'Price' dimension is found to be a meaningful factor to the group categorized not having "will buy the service again" and "will suggest to others" criteria(p<0.05).

Effect of Excess Calcium and Iron Supplement on Iron Bioavailability, Liver and Kidney Functions in Anemic Model Rats: Joung Hyun Lee, Yeon Sook Lee; Korean J Community Nutr 2000;5(2):243-252. Published online July 31, 2000

Abstract PDF: This study examined the effects of excess intake of calcium(Ca) and iron(Fe) supplements on iron bioavailability, liver and kidney functions in anemic model rats. Seven-week-old female rats were first fed and Fe-deficient diet for ten weeks, and then fed one of nine experimental diets for an additional eight weeks, containing three levels of Ca, normal (0.5%) or high(1.5%) or excess (2.5%) and three levels of Fe, normal(35ppm) or high(210 ppm) or excess(350ppm). In anemic model rats, serum Fe, total iron binding capacity(TIBC), hemogolin(Hb), hematocrit(Hct) and liver Fe contents were significantly decreased. Apparent Fe absorption significantly increased with increasing dietary Fe levels, and decreased with increasing dietary Ca levels. serum Fe concentration significantly increased in rats fed a high- and excess-Fe diet, and decreased in rats fed a excess-Ca diet. TIBC was decreawed in rats fed a excess-Ca diet, and transferrin saturation(%) increased in rats fed ahigh- and excess-Fe diet. Hb and Hct were decreased in rats fed an excess-Ca diet regardless of dietary Fe levels. Fe and thiobarbituric acid reactin gsubstance(TBARS) Contents of liver significantly increased in rats fed a high- and excess0-Fe diet, and decreased in rats fed a high- and excess-Ca diet. Fe content of the spleen showed similar results. Urinary creatinine and GFR increased in rats fed an excess-Ca diet regardless of dietary Fe levels. GOT, GPT and LDH were not significantly affected by dietary Ca and Fe levels. These results suggest that excess intake of Fe may increase liver Fe deposits and TBARS, and excess intake of Ca may decrease Fe bioavailability and kidney function leading to potential health problems in anemic model rats.

Current Information and Sanitaion Status of Professional Catering Companies: Whachun Yoo; Korean J Community Nutr 2000;5(2):253-262. Published online July 31, 2000

Abstract PDF: A survey was performed to provide current information on professional catering companies. Twenty-three catering companies out of thirty-eight(60% recovery) responded the survey for December in 1998. Foodservice establishments managed by 16 small-middle sized catering companies provided an average of 11,200 meals daily, while those managed by major and small-middle sized catering companies were mainly office(72.2%, 57.1%) and school foodservice(15.2%, 26%). The rates of sales of major catering companies and small-middle sized catering companies increased 24%, 30% respectively in 1998. Self-evaluation in catering companies was conducted for sanitary management. Unsatisfactory results from self evaluation were found in three categories, such as, measurement of internal temperature of food materials at reception, ventilation system in the working area, and hand-washing stations with equipment cleaning and sanitizing facilities in front of the working area. Most catering companies expressed a willingness to apply the Hazard Analysis Critical Control Point (HACCP) system from this survey. "Professional catering business has arisen as an area requiring more consideration and further study for the production of a safe food."

A Longitudinal Study of Calcium and Phosphorus Intakes of Korean Infants from 1 to 3 Months in Breast-Fed vs Formula-Fed Infants: Korean J Community Nutr 2000;5(2):273-279.

Abstract PDF: This study was carried out to evaluate the calcium and phosphorus intakes and correlation with growth performance of 25male breast and formula-fed infants from 1 to 3 months postpartum. There were four groups breast-fed(BF) and three formula-fed groups(FFM, FFN and FFP). There was no significant difference in the height and weight of infants according to feeding methods and formula brands. Milk intake and the concentration of calcium and phosphorus from human milk and the formulas were measured. The average calcium content of human milk was 26.6$\pm$4.1mg/dl and 13.5$\pm$2.0mg/dl, respectively. The average calcium intakes of the brest-fed and formula-fed infants were 205.5$\pm$29.3mg/day and the 460.5$\pm$70.6mg/day, respectively the average calcium intake of breast-fed infants was significantly lower than that of formula fed infant. The percent of RDA(41%) of breast-fed infants was lower than that(75.4%) of formula fed infant. The average phosphorus intake of the brest-fed and formula-fed infants were 105.1$\pm$20.1mg/day and 288.3$\pm$37.3mg/day, respectively. The precent of RDA(27%) for brest fed was significantly lower than that(75.4%) of formula fed. The Ca/P ratios were 2.1 in brest fed and 1.6 in formula fed infant. The average calcium and phosphorus intakes of the formula fed infants was higher than that of the brest-fed infants. This data suggests the calcium and phosphorus intakes form human milk sufficiently support the growth of infants. Therefore, the level of calcium and phosphorus recommended dietary allowances for infants should be reduced.

Comparisons of Nutrient Intakes, Dietary Behavior and Perception about Body Image between Adolescent Body and Girls in Rural Area: Korean J Community Nutr 2000;5(2):280-288.

Abstract PDF: This study was undertaken to compare the obesity related dietary factors among rural middle school students living in Korea. Anthropometric data showed that mean height and weigh were 161.7$\pm$13.0 and 49.8$\pm$10.3kg in 226 male students and 158.3$\pm$6.1 and 48.2$\pm$7.5kg in 212 female students. Mean BMIs for boys and girls were 19.10$\pm$2.47 and 19.26$\pm$2.35, respectively. 71.68% of male students and 72% of female students were underweight by the BMI index. The BMI of older students was higher than young ones in both sexes. Most nutrient intakes of the subjects were below the RDA. In particular Ca and Fe intakes were extremely low in both sexes. 66.88% of the students skipped breakfast and it was found that the reasons for missing a meal for both sexes were significantly different. Compared to males, more female respondents felt guilty and depressed related to eating. Furthermore, females were more significantly concerned with body image, diet, and body weight(p〈0.001), and they were not satisfied with their weight. The sources of information on obesity and diet were from radio and TV in males while females got information from magazines and friends. In male students their ideal body weight was higher was higher than actual body weight. In contrasting, female students desired a thin body shape. A different approach for nutrition education for adolescents should be developed and implemented based on sex.

Relationship between Serum Levels of Microminerals and Lipids in Korean Adults on Self-Selected Diet: Korean J Community Nutr 2000;5(2):289-296.

Abstract PDF: The purpose of this study was to investigate the relationship and lipids in healthy adults on self-selected diets. These subjects consisted of 40 female college students residing in Chungnam. Anthropometric measure-ments, diet intake measurements, and blood collection were conducted. Serum concentrations of 5 microminerals(As, Cr, Mn, Se, Ni), lipids(triglyceride, total cholesterol, HDL-cholesterol), and glucose were measured by an ICP spectrometer and biochemical analyzer. The results were as follows. The mean age of the subjects was 22.34 years and the mean weight, height, and BMI were 52.89kg, 161.29cm and 20.34, respectively. The mean serum concentrations appeared to be 14.60ug/dl(As), 1.87ug/dl(Cr), 0.18ug/dl(Mn), 23.50ug/dl(Se), 0.21ug/dl(Ni), 60.73mg/dl(triglyceride), 138.49mg/dl(total cholesterol), 65.95mg/dl(HDL-cholesterol), 60.39mg/dl(LDL-cholesterol) and 88.82mg/dl(glucose). When analyzed by Pearson’s correlation coefficient, the serum concentration of Cr was negatively correlated with Ca and vitamin B12 intake(p〈0.05, p〈0.05) respectively, Mn was negatively correlated with Na intake(p〈0.05), Ni, however, was positively correlated with K intake(p〈0.05). The serum concentration of Se was positively correlated with LDL-cholesterol(p〈0.05), Ni, however, negatively correlated with total cholesterol, HDL-cholesterol, LDL-cholesterol, and glucose, respectively(p〈0.001, p〈0.01, p〈0.05). Further studies are needed to clarify the precise micromineral intakes, nutritional assessment of microminerals, and cause-effect relation of microminerals and serum lipids.

Relationship between the Number of Different Food Consumed and Nutrient Intakes: Korean J Community Nutr 2000;5(2):297-306.

Abstract PDF: In order to examine the relationship between the number of different foods consumed and nutrient intake, one-day food consumption were surveyed by 24-hour recall from a sample of 287 individuals(20-49 years) living in Daejon City. The number of consumed food items did not include seasonings except red pepper power, sugar, oil, and soybean paste when used in large amounts(DVS). The number, including all seasonings except salt and vinegar(DVSS), was also counted. Of the total subjects, 43.6%(DVS) or 39.0%(DVSS) consumed 18-23 daily different foods with an average of 20.2 or 22.9, respectively. As the DVS increased, daily intakes of total foods and most food groups were elevated. Cereals however were not changed and eggs were decreased with increasing DVS. Energy and nutrient intakes and their mean adequacy ratio(MAR) and index of nutritional quality(INQ) also show positive correlations with DVS. MAR equal to or greater than($\geq$) 0.75 was taken as a cut-off point for nutritional adequacy. In that case, the mean INQ was shown to be $\geq$1. MRI(10) for energy and 9 nutrients and MAR(3) for Ca, vitamin A, and riboflavin were estimated. Form a regression analysis, when MAR(10) was 0.75, the DVS and DVSS were assumed to be 19.6 and 22.2, respectively. And when MAR(3) was 0.75, the DVS and DVSS were assumed to be 31.6 and 34.6, respectively. However the subjects whose MAR(3) was 0.75(0.7-0.8) 23.8(DVS) or 26.6(DVSS) different foods in average, and their mean intakes of energy and all nutrients, except vitamin A, were ranged at 85-100% of the RDA. Of the 74 subjects who consumed DVS$\geq$24, 24 to 42 numbers took 〈75% RDA of Fe, Ca, riboflavin, and vitamin A. And five of 7 who consumed DVS$\geq$32 took $\geq$125%RDA of protein, which showed concerns of overnutrition in case of DVS$\geq$32. Form the above results it could be suggested that a daily intake of 24-32(or 28) of DVS or 27-35(or 31) of DVSS was recommendable for an optimal nutritional of all nutrients if the variety of food groups and sufficient intake of vitamin A and calcium were emphasized together.

Comparing Health-related Behaviors, Food Behaviors, and the Nutrient Adequacy Ratio of Rural Elderly by Single-elderly Families vs. Extended Families: Korean J Community Nutr 2000;5(2):307-315.

Abstract PDF: The aim to this study was to investigated the effects of family type on the health-related behaviors, food behaviors, and nutrient adequacy ratio of the elderly. Studies were performed on 109 home-bound elderly in a rural area of Asan city, in 1996. Subjects were divided into two groups by their family type, one was single-elderly family(n=58) and the other was extended family(n=51). The results obtained by questionaires and personal interviews as follows. 1) The average age 68.6. They served in primary industry, and 89.1% of responders received less than a primary school education. There was no significant difference by family type. 2) Single-elderly family members themselves felt more negative about their health than extended family members. 3)Each nutrient adequacy ratio of single-elderly family/extended family members was 0.72/0.76 of energy, 0.73/0.76 of protein, 0.59/0.66 of Ca, 0.98/0.99 of Fe, 0.62/0.74 of vitamin A, 0.86/0.87 of thiamin, 0.72/0.73 of riboflavin, 0.71/0.77 of niacin, 0.90/0.91 of ascorbic acid, and 0.76/0.80 of Mar. The NAR of vitamin A of the single-elderly family members was significantly lower than for extended family members(p〈0.05). Energy, protein, Ca, vitamin A, riboflavin showed insufficient intake for both groups. The percentage of INQ〈1 of the single-elderly family/extended family members was 45.6/51.0 of protein, 66.7/66.7 of Ca, 64.9/56.9 of vitamin A. By NAR and INQ, the most insufficient nutrient to the elderly in this rural area was Ca. We there for suggest that it is needed for elderly in rural areas to receive of food that is higher ING of Ca.

An Evaluation of the Nutritional Quality of Packaged Meal(Dosirak) Feeding of Adolescent Males in Kangnung: Korean J Community Nutr 2000;5(2):316-323.

Abstract PDF: This study was carried out to evaluate nutritional quality of the dosirak severed by 3 Dosirak manufacturing establishment in Kangnung. The subjects of this study came from 3 different male high schools in Kangnung. The portion amounts of Dosirak were weighed and the food intake was measured by substracting the leftover from the averaged portion amount. The leftover was measured by a modified aggregate selection plate waste measurement technique. The nutrient intakes were analyzed by a computer aided nutritional analysis program for professionals(CAN pro). The menu of the dosirak was too simple. The total amount of Dosirak was 714g and the percent of plate waste was 714g and the percent of plate waste was 7.2%. The male high school students were taking adequate energy, but the nutrients which did not meet 75% of the 1/3RDA(Recommended Dietary Allowances) were Ca, Fe, and vitamin B$_2$.

Assessment of Customer Satisfaction of Service Quality in University Foodservices: Korean J Community Nutr 2000;5(2):324-332.

Abstract PDF: The purpose of the study was to assess customer satisfaction concerning service quality characteristics of university foodservice by using a developed DINESERV model. In particular, it was intended to develop a tool to assess the difference between customer judgements on importance and customers perceptions with actual service delivery by university foodservices. Quenstionnaires were distributed to 1,000 university students. A total at 820 university students responded with a usable response rate of 77.7%. A statistical data analysis was completed using SAS programs for descriptive analysis; a t-test, chi-square test and Dunan's multiple range test. The results of the study are as follows; 1) The mean number of students visiting university foodservices per week for males was larger than that of females. The students' first choice depended on distance when they selected foodservices. They answered their preference as the first factor when they order a particular menu items in foodservices. The first complaint factor concerning university foodservices was the price of the food. 2) Customers was not satisfied with the quality of the service of university foodservices. The important mean score of the service quality was 3.63 out of 5, but the perception mean score of the service quality was 2.87. Therefore, there was a gap(0.76) between the importance score and perception score. 3) Customers' satisfaction with the service quality by dimensions wee int he follow order: assurance>reliability>responsiveness>tangibles>empathy. Customers were more satisfied with the service quality of contracted management than that of self-operated facilities.

A Simulation Study on Microbiological Evaluation of Kimbap Manufacturing Process in Summer and Winter: Korean J Community Nutr 2000;5(2):333-342.

Abstract PDF: The purpose of this study was to evaluate microbiological quality for each stage of the kimbap manufacturing process in summer and winter. Under the various controlled conditions through the simulation, the time-temperature data were collected and the microbiological quality(including total plate count, coliforms, and fecal coliform count) were evaluated. To determine the expected shelf life of Kimbap, a microbiolgical analysis according to the length of the storage time was performed. The microbiological analysis on both sanitary and unsanitary utensils was compared. The microbiological quality of the raw materials of Kimbap in summer was not at an acceptable level, but that of the heat-treated raw materials of Kimbap met the requirement according to the standards set by the Natick Research Center. The number of the microorganisms of the unsanitary utensils and the Kimbap made from unsanitary utensils was more than the acceptable criteria. Sanitary management is necessary to prohibit cross-contamination and to manufacture Kimbap safely. Results from storage times and storage temperature conditions(chilled and room-temperature storage) showed that the expected shelf-life of the Kimbap with the room-temperature storage was as less than 3 hours in summer, while it was as 7-10 hours in winter.

A Survey of the Model Nutrition Services in Community Health Centers: Korean J Community Nutr 2000;5(2):343-351.

Abstract PDF: The Korean government enacted the National Health Promotion Act in January, 1995 and proclaimed its regulations and rules in September 1995, which became the basis of the national health policy. The health promotion programs consist of education for health, prevention of diseases, improvement of nutrition, and practice of healthy life style as defined in that Act. The Community Health Act was amended in 1995, which included implementing nutrition services in community health centers. The purpose of this report is to summerize the nutrition services conducted in 32 community health centers. the main nutritional activities were as follows : 1) nutritional guidance by counseling and education for pregnant or lactating women, infants, preschool children, and those with chronic diseases, 2) collection, analysis, and interpretation of data collected from the community, on background conditions and target population for the assessment of community needs, 3) evaluation of nutritional status of population in the community 4) nutritional guidance for mass feeding in different institution including schools and welfare institutions. In order to meet the government's expectations and desires, the community health centers have made continuous efforts to put nutritional activities into practice in the community. However, there are constraints, such as relative staff shortages, lack of funds, and information which hampers the nutritional activities.
