The purpose of this study was to evaluate nutrient and food intake status and dietary, quality according to obesity based on nutrient and food group intake, in female university students. Surveys were conducted using questionnaires and 3 days, dietary record in 360 female university students residing in Seoul. The subjects were divided into two groups by percent of body fat: an overweight group(percent of body fat more than 23%, n=249) and normal group(percent of body fat below 23%, n=111). The overweight group had a larger proportion of subjects who binged compared to the normal group. There was no significant difference in energy intake between the two groups. The densities of plant calcium and dietary fiber in the overweight group were significantly lower than those of the normal group. However, animal fat density was significantly higher in overweight subjects. The Korean's dietary diversity score(KDDS) of the overweight group was 4.65, and that of the normal group was 4.67, indicating no significant difference. There was no significant difference of DQI-I between the overweight group(50.8) and normal group(51.1). However, the macronutrient ratio score was significantly lower in the overweight group. These results indicate that overweight female college students may have improper dietary habits, and have lower overall balance aspect macronutrient ratios.

Although a generation-related difference in nutrient and food-group intake has been broadly recognized in the Japanese population, few studies have examined the difference and correlation of intakes with consideration of a family line and co-habitation status. We conducted a dietary survey using female college students in dietetic course in Aichi, Japan, and their mothers and grandmothers. A validated self-administered diet history questionnaire was used for assessment of intakes. Data from 110 families were included in the analysis. The means of 13 nutrients and 10 food groups (of the 15 and 14, respectively) showed significant differences among the three generations. A significant difference was observed in the carbohydrate, protein, saturated fatty acid, cholesterol, and fish intakes between the students living with their mothers and those apart. In the correlation analyses between generations, moderate correlation was observed for most nutrients and food groups between the students and their mothers living together (correlation range = 0.30-0.61 for nutrients, and = 0.21 -0.56 for food groups). A wide variation with no consistency was observed for the correlation between the students and their grandmothers (-0.18 -0.59 and -0.33 -0.65, respectively), No meaningful correlation was observed between any two generations living apart. Among the food groups examined, pulses, fish, and vegetables showed relatively large differences for the correlation between two groups with different living conditions. When living together, the correlation coefficients for nutrients and food groups between the students and their mothers decreased according to the increase in frequency of eating out by the students. These results suggest that living together and eating together were an important factor for the resemblance in dietary habits between generations in the population with a marked generation-related difference in intakes.

This study was conducted with 20 female gymnasts to examine the relationship between eating patterns, diet menstrual function and hematological status. According to the baseline data a nutrition counseling and education program was developed and evaluated improved the nutritional status and health of female gymnasts. Mean body weight at the onset of the study was 42.1$\pm$7.0kg and was reduced to 41.8$\pm$6.1kg after the nutrition counseling and education program. The percent of body fat was significantly reduced from 13.9$\pm$3.7% to 13.1$\pm$3.1%(p<0.01) skinfold thickness of subscapular and thighs was reduced significantly(p<0.01, p<0.05) Mean daily intake levels of energy, protein calcium iron thiamin riboflavin and niacin were significantly elevated after the nutrition counseling and education program but were lower than the Recommenced Dietary Allowances. For the nutrition knowledge and food habits, the posttest mean scores showed a significant increase. The hematological status(hematocrit, serum ferritin) and the early follicle level of estradiol were elevated to a mild degree although it was not significant,. The follicular stimulating hormone level was elevated significantly(p<0.01) Gymnastica has been one of the sports implicated by the medical profession as having probable detrimental effects. The implications of such training to childs growth and maturation have yet to be determined . Most female athletes, however, experience poor nutritional status and delayed puberty The priorities were to prepared a more effective nutrition program and education material status and delayed puberty. The priorities were prepared a more effective nutrition program and educational material for athletes coaches and adminstrators to prepare guidelines for the team physicians and coaches to follow for the physical and physiological examinations of female athletes.

The amount of salt intake of Korean people is 11.4 grams per a day, which is 2.3 times of the recommended daily salt intake by WHO - 5 grams of salt a day. The relationship between high salt consumption and increased risk of high blood pressure, observed not only in hypertensive but also in normotensive patients. High salt intake is also associated with an increased risk of heart attack, cerebral ischemia and osteoporosis. Therefore, this research is for developing a salt taste sensor to reduce sodium consumption and improve meal habits for the perception of a more bland taste of most foods. When the sensor was put into food sample, current intensity achieved with distribution cables. Current intensity was correlate with a simple equivalent of salt taste stimulus intensity. The salt taste sensor consists of salinity & temperature measuring probe, signal processing circuit and LCD display & LED warning light. When salinity is going over a set point, LCD displayer indicate salt taste on LCD panel by percent value (%), and at the same time, blue LED light change to red LED light. So we could know the grade of salt taste in soup before meals conveniently and objectively. The results show that operating range of 10 to $80^{\circ}C$ and accuracy of ${\pm}0.1%$ were achieved with an analysis time of about 2 or 3 sec. Moderate reductions in salt intake can help to avert adult diseases and lead a healthy life.

The comparative feeding ecology of greenling Hexagrammos otakii and Schlegel's black rockfish Sebastes schlereli populations was investigated in the Jangbong tidal flat near Incheon, Korea. Monthly samples were taken using a modified otter trawl from November 1999 to January 2001. The stomach contents of 124 greenling and 115 Schlegel's black rockfish were analyzed. The diet of H. otakii was dominated by the amphipods Gammaropsis iaponicus, Caprella scaura, Isaeopsis sp. and Monocorophium acherusicum, the shrimps Latreutes mucronatus and Alpheus japonicus, the mysid Neomysis orientalis and the bivalve Mytilus edulis. In contrast, S. schlegeli mainly fed on the mysids N. orientalis, N japonica, and N. awatschensis, the shrimps Exopalaemon carinicauda, A. japonicus and L. mucronatus, and the fish Pholis fangi and unidentified gobiids. A comparison of the frequency and abundance of food items showed that crustaceans (e.g. amphipods, mysids and shrimps) were important foods for both species. Their main dietary components, however differed which is probably due to differences in the spatial distribution of the two species and their prey items. In conclusion, greenling and Schlegel's black rockfish, despite being sympatric on a tidal flat have distinct food habits and low dietary overlap (Schooner's index: 0.1). These results indicate, to some extent, resource partitioning for the maximum utilization of available foods in the tidal flat.

BACKGROUND/OBJECTIVES: The objective of this study was to determine dysphagia risk among community-dwelling elderly people living at home. We also examined the impact of socio-demographic variables on dysphagia risk as well as the relationship between dysphagia risk and dietary characteristics. SUBJECTS/METHODS: The study sample included 568 community-dwelling individuals, aged 65 years and above, who were living independently in their own home in Seoul, Gyeonggi, or Gwangju in South Korea. We used a dysphagia risk assessment scale to screen for dysphagia risk and the Mini nutritional assessment to evaluate the nutritional status. Associations between dysphagia risk and other variables were assessed using logistic regression analysis. RESULTS: Of the 568 subjects, 350 (61.6%) were classified into the dysphagia risk group (DR) and 218 (38.4%) were classified into the normal group (non-DR). Being female (odds ratio (OR) = 1.82, 95% confidence interval (CI) = 1.28-2.59), being 75 years and older (OR = 2.40, 95% CI = 1.69-3.42), having a lower education level (OR = 2.29, 95% CI = 1.33-3.97), and having a lower perceived economic status (OR = 2.18, 95% CI = 1.32-3.60) were more frequently observed with dysphagia risk compared to those who did not have such characteristics. Lowered mastication ability (OR = 14.40, 95% CI = 4.43-46.95), being at risk of malnutrition or malnourished (OR = 2.72, 95% CI = 1.75-4.23), lowered appetite (OR = 3.27, 95% CI = 2.16-4.93), and decreased food intake (OR = 2.95, 95% CI = 1.83-4.78) were observed more frequently in the DR group than in the non-DR group when adjusting for potential confounding factors. CONCLUSIONS: It is necessary to develop and apply integrated programs to improve the dietary habits and nutritional status of elderly individuals at risk for dysphagia, especially for women aged 75 years or older with lower educational and economic levels.

The purposes of this study were to describe systemically 18 years of oncology nursing research in Korea and suggest it's direction in future. 149 nursing studies published from 1980 to 1998 were selected for the present study. There were examined the source and the design of study, type of subjects, measurement variables, the intervention outcome of experimental research, and theme of qualitative research. The results were as follows : 1. 121 of 149 studies were composed of master thesis and dissertation of graduate school. There were 55 correlations, 30 descriptions, 19 comparisons, 19 qualitative studies and 2 Q-methods as the type of research design. 2. Cancer patients without describing specified diagnosis as subjects' characteristic were 44 of total studies. The others had various diagnoses such as gastric cancer, uterine cancer, breast cancer, leukemia, lymphoma, colorectal cancer, and lung cancer. According to treatment type, patients receiving chemotherapy were the highest number distribution as 53 of all researches. 3. Most measurement instruments used for research were translated it into Korean that developed by foreigners, such as Zung's depression, Spielberg's anxiety, and Wallston's locus of control. 4. Quality of life was shown the most frequently among correlational researches. the next one was depression, the third was hope, and so on. 5. There was the most frequent comparison between cancer and non-cancer patients in comparative researches. It was surveyed those variables as diet habits, risk factors, stressful life events, anxiety and depression, and self-care capacity between two groups. 6. The subjects were mostly chemotherapy patients as 15 of 24 experimental studies. Oral care and education were respectively the highest experimental interventions. 7. Qualitative researches about cancer were reported since 1991. Their themes were illness experience, adaptation process, dying experience, family experience, hope, caring, experience of health behavior, meaning of chemotherapy and experience of cancer survivor. Phenomenologic methodology was designed above 50% of qualitative researches. According to the above findings, cancer research had increased since 1990 and done mostly by descriptive design but a few experimental studies. As recommendations for the future, It is necessary to study the comparison of oncology nursing research internationally, the replication to establish the effect of nursing intervention, and the family care of cancer patient.

Background and purpose : Stroke is a leading cause of death in Korea. Early measures to prevent stroke are extremely important since it has no cure. Korean might have different risk factors since their dietary habits and socio-economical status differ from most western countries. However, the risk factors for stroke in Korea have not yet been identified. Moreover, the lifestyle of healthy Korean adults has not been investigated. In this study we investigate the lifestyle of healthy adults living in Seoul and rural areas and compare the lifestyles of the two. Methods : One hundred seventy one subjects were studied. Among the subjects studied, 128 were from Seoul, the other 43 were from the country area. The age of the subjects was limited to over 40 years. Blood pressure, fast blood sugar, and cholesterol were measured. The subjects' height, weight, body mass index, total body fat, skinfolds thickness of triceps, subscapular and abdomen were measured to determine obesity. Using a structured interview, we assessed : sodium intake, physical activity and exercise, consumption of vegetables, fat, fish and fruits. The results of the two groups were compared. Results : There were no statistical differences in age and education between the two groups of subjects. The mean age of the subjects were 66 years old. The subjects residing in rural areas had a higher intake of sodium(p<0.05), lower physical activity(P<0.05), and higher BMI and body fat (p<0.05) as compared to the subjects in Seoul. Subjects with hypertension were between 24% and 33% and the prevalence of hypertension was the highest when compared to the prevalence of DM or hypercholesterolemia. However, the prevalence of hypertension, DM, hypercholesterolemia, were not significantly different in these areas. Conclusion : Our results show that subjects living in rural areas eat more salty food, exercise less, and tend to be obese. The finding of this study lead to speculation that Korean living in rural areas have less information about the effects of diet on health than city dwellers do. General health and nutrition education programs aimed at the prevention of stroke and other such conditions for rural area Koreans may close the risk factor gap between rural and urban dwellers.

The population with massive waist circumference is increasing in comparison with that with obesity in entire bodies in Korea. It is assumed that prevalence of obesity is closely related with changes in marriage status such as divorce or separation by death, and age, educational background, diet habits and living environment depending on presence or absence of spouses. To identify whether there are relations between spouse, BMI and waist circumference under the conditions such as life cycle age, educational level, income, smoking, drinking and walking controlled, this study used data of national health and nutrition research organized by Korea Center for Disease Control and Prevention. The subjects of the study were a total of 7,178: 3,043 men and 4,135 women whose ages were above 19 and married. As a result of controlling independent variables except a factor of spouse, there were no statistically significant relations between presence of spouse, waist circumference and BMI in men, but odds rate of waist circumference was lower, 0.78(95% CI 0.636-0.954) when the female subjects had no spouse than when they had spouse.

The present study was conducted to devlop and appropriate retirement home model for the elderly in terms of clothing and textiles; nutrition, health, and foodservice; housing and environment; and psychological adaptation. Specifically, the purposes of the study were: 1) to provide basic guidelines for clothing by comparing the clothing behavior of the elderly living in the retirement home and those living in their own homes with family, 2) to provide basic guidelines for balanced diet and effective foodservice, 3) to develop an ideal life space and facilities, and 4) to assess the psychological characteristics of the elderly. Questionnaires, observation, experimental method, and survey of literature were used for the study. Clothing behavior showed that the elderly were much concerned about clothing, and they preferred comfortable as well as fashionable designs. The elderly in the retirement homes complained of a lack of quantity and variety in clothing. They preferred natural fiber rather than blended fabrics. Flame resistance, thermal insulation, and flexibility of textile fabrics were found to be prime considerations in manufacturing and selecting clothing materials for the elderly. The health status of the surveyed elderly was generally good, but some poor eating habits were observed. Dietary nutrients intakes were generally sufficient, but several nutrients intakes were insufficient. The level of equipment in the kitchens of the institutions was low. Furthermore, the employment rate of dietitians in institutional settings was extremely low. This resulted in a lack of systematic foodservice management. Residents in the institution were generally satisfied with present life space and facilities but this was mainly because of abandonment, adaptation, and past experience. Optimal allocation of residents per bedroom and an adequate design for storage, bathroom, utility room, and dining room were recommended. The comparison of psychological status of the elderly living at home was more stable than those living in an institution. The emotional state of the elderly living in the institution was characterized by loneliness; they did not have close interpersonal relationships or future plans. An appropriate model for the elderly was developed on the basis of these findings.
