In experiment 1, dietary self-selection of the 3 macronutrients, protein, fat, and carbohydrate were examined in male rats given 3 food cups of 80% carbohydrate, 80% protein, and 70% fat diets simultaneously. All the rats showed normal growth pattern and organ weight, which means they have ability to select just right kinds and amounts of nurients in order to support their growth and development. Mean values of caloric intake, body weight gain, serum lipid values and empty carcass compositions were not significantly differ between the upper and lower quartile groups of fat proportion of empty carcass compared to the lower quartile group(LF). Same feeding design was employed in experiment 2 where the effect of mild electric stress on food selection was studied. The rats in both control and electric stress group revealed a normal growth curve and organ weights. The rats in both control and electric stress group revealed a normal growth curve and organ weights. The stress group showed higher caloric intake and body weight gain than control group, but no significant effects of stress on serum and empty carcass components was found. Even though normal rats seemed to select macronutrients according to their physiolosical needs, there were individual differences in food selection whether they were exposed to stress or not. Therefore life long individual food selection pattern may have a great influence on nutritional status and chronic degenerative diseases of eldery, and on aging process.

PURPOSES : The purpose of this paper is to demonstrate to the practicing engineers, how to apply the advanced composite materials theory to the road structures. For general construction material used, there is certain theoretical limit in sizes. For super road structure construction, the reduction in panel weight is the first step to take in order to break such size limits. METHODS : For a typical road structures panel, both concrete and advanced composite sandwich panels are considered. The concrete panel is treated as a special orthotropic plate. RESULTS : All types of advanced composite sandwich panels are considered as a self-weights less than one tenth of that of concrete panel. The concrete panel is treated as a special orthotropic plate to obtain more accurate result. CONCLUSIONS : Advanced composite sandwich panels are considered as a self-weights less than one tenth (10%) of that of concrete panel, with deflections less than that of the concrete panel. This conclusion gives good guide line for design of the light weight of road structures.

The purpose of this study was to investigate relationship between the eating behavior, physical and mental health. For this purpose, the data was collected by using questionnaires and intervews distibuted to 293 the elderly residing in Seoul. This study was designed to observe the eating behavior(eating habit, healthy food preference, smoking, drinking), physical health(weight, height, desease and heath of the current and past, self-awareness of the health) and mental health(weight, height, desease and heath of the current and the past, self-awareness of the health) and mental health(meeting, excursion, exercise, service, activi ty, depression). The major results are: 1. The heathy elderly had the better eating habit and the non healthy tried to stop smoking and drinking for their own health. 2. There were many elderly with neuralgia and arthralgia, especially women were worse. The sleep disorder related to many disease. When physical health was bad, so was mental health. 3. More than 50 percentage of subjects had light depression, especially women and the elderly at 60-75age were more serious. The depressive elderly had no meetings, excursion, exercise, service activity and showed a hight tendency for under-weight or obesity. In conclusion, the relationship between the eating behavior and physical and mental health wa very significant, so it was necessary to provide comfortable living condition to the elderly.

In order to investigate the relationship among physical status, eating habits and life style, this survey was carried out by questionnaire in 1996. College students(413 cases) who resided in Chuncheon answered. The results are as follows: 1) The means of height and weight were $173.9\pm{5.0cm}$, $64.5\pm{8.3kg}$64.5$\pm$8.3kg in male students and $160.9\pm{4.5cm}$, $51.1\pm{5.8kg}$ in female students. 2) Under 20 of BMI(Body Mass Index) were 23.0% of male students and 58.3% of female students. 6.7% of males and 3.0% of females were over 25 of BMI. 3) There was a significant relationship between the type of favorite snacks and gender. There was a significant difference of BMI according to the level of the frequency and the amount of drinking alcoholic beverages. 72.6% of subjects took exercise regularly. But the BMI of subjects taking regular exercise and watching the weight tended to be higher than that of subjects not doing so. 4) Most students(78.5%) skipped breakfast, which was higher in the self-boarding students in than any other. It was because of the lack of time that they skipped their meals. This study suggests that a comprehensive nutrition education program is needed for college students in self-boarding houses and dormitories to improve their eating habits about skipping meals, and especially for female students to prevent inappropriate weight control.

This study was to examine the effect of standards of selecting jeans and appearance management behavior on leisure lifestyle. Questionnaires were administered to 253 college students living in Deagu and Kyoungbuk. Data were analyzed by using frequency, factor analysis, regression analysis, t-test, and ${\chi}^2$-test. The findings are as follows. Factor structure of each concept appeared to be brand-valued, functionality valued and design-valued for standards of selecting jeans, diet management, exercise management, weight management and appearance satisfaction. Leisure lifestyle consisted of sports activity-type, sociality-type and self-management-type while value lifestyle consisted of active sociality-oriented, family-oriented and economic feasibility-oriented. There was a significant difference in brand-valued and design-valued of standards of selecting jeans and in frequency of wearing jeans male students showed higher than female students. The result of this study showed brand-valued, diet management, exercise management, weight management, and appearance satisfaction had significant effect on sports activity-type and design-valued and weight management had significant effect on sociality-type. Brand-valued affected self-management-type significantly and brand-valued, design-valued, diet management and appearance satisfaction had a significant effect on active sociality-oriented and brand-valued and diet management affected family-oriented.

Self-reciprocal polynomials over finite fields are useful in several applications, including reversible codes with read-backward properties. This paper is a study on 90/150 CA with characteristic polynomials of maximal weight polynomials, which is one of the self-reciprocal polynomials. In this paper, we propose a decision method for determining the existence of 90/150 MWCA corresponding to the maximum weight polynomial of degree 2n using n-cell 90/150 CA with transition rule <$100{\cdots}0$>. The proposed method is verified through experiments.

Purpose: To provide the epidemiological information for developing preventive programs encourage appropriate eating and weight control behaviors. Method: 349 college students in Seoul were administered self-report question- naires to examine eating habits, trend of disordered eating, weight reduction practice and body size evaluation from September to October 2002. Data were analyzed by SAS program for frequency, t-test, ANOVA with Scheff test. Result: The mean eating score was moderate and it differed by subjects' characteristics. The mean score of EAT-26 was relatively lowered, and 3.4% of the subjects score showed disordered eating behavior. It differed significantly by subjects' general characteristics. 30.4% of total sample were currently trying to lose weight and had interested in trying to lose weight. EAT-26 was significantly different by weight reduction practices and interest. Perceived body size differed by the score of eating habit and EAT-26. Conclusion: It can be suggested weight preoccupation have a relation to eating habits, weight control practice and disordered eating. Further study is recommended educational interventions targeting at-risk subjects.

The plant growth and yield of Pinellia ternata (Thunb.) Breit. were studied by altitude and tuber weight. The emergence rates in low land area were not different by tuber weights, but it showed earlier emergence date in heavier weight of seed-tuber and low land area. The higher aerial growth such as plant height and number of leaves per plant was the heavier tuber weight in a planting year, but the growth was not different by the weight of tuber at second year after planting. The distribution pattern of tuber size per $m^2$ was not influenced by different seed-tuber weight. The number of harvested tuber was highest at more than 1 g of tuber weight, and followed 1~2 g and less than 2 g. The distribution pattern of fresh tuber yield was not influenced by different altitude and seed-tuber weight. The marketable tuber, 2 g or more, tends to be produced with more than 0.6 g seed-tuber. As the results above-mentioned, it was thought that the high yield was supposed to use seed-tuber over 0.6 g in the fertile soil.

Thinness has become a symbol for beauty acceptance and competence for women in our society especially for young college women. Relatively little is known about characteristics of women who are dissatisfied with their shape or weight and who are interested in performing weight control program. Four hundred college women in Seoul and Kyunggi-Do area were surveyed from November to December 1992 to investigate the relationship between the concern about weight control and various aspects of food related behaviors. The purpose of this research was to investigate the relationship between the weight concerns of college women and their aspects of several eating behaviors. Self-developed questionnaire was used after validity test. The results were as follows: 1) The average height weight and BMI value of subjects were 160$\pm$4.5cm 51.02kg and 19.86$\pm$4.5 respectively. 2) The 49% of subjects were highly concerned about weight control(high interest group) and 39% were moderate concerned(moderate interest group). 3) The average BMI and weight change per year were significantly higher in the high interest group than other groups. 4) The score of nutrition knowledge was also higher in the high interest group, 5) There were no significant differences among groups in the meal frequencies. and amount of nutrients intake. 6) The signs of eating trouble were found in subjects 59.0% of subjects felt feareness about weight gain after consumption of large amount of food. 7) The ratio of CPF was 64:14:22 and nutrient adquacy ratio(NAR) of energy was 0.94 NAR of Fe was 0.84 the other NAR of nutrient over 1.0.
