The purpose of this paper is to develop the software for the diagnosis and evaluation of the nutritional ingestion status of inviduals or a group of family members who have inhabited in rural and urban, based on the suggested amount of nutrition and foods. This software can be used for the computation for the needed amount of nutrition, which is suitable to the economic conditions of individuals and group of family members, and for the reduction of effort to plan the balanced table menu and effort to manage the diets. However, those commercial softwares were hard to be purchased and expensive for the users, and even if they were purchased, it needs much time and efforts to operate and run the program. Especially those commerical software were not possible to revise when the user has faced with the need to revise and complement the input data according to his situations such as the individuals and the group of family members. The software which was developed to treat the table menu and the nutrition was very limited to the particular persons. That is, the software was not for the evaluation of the nutrition synthetically and reasonably, because it was planed to use for the patients and the group of hospital and research centers. However this software has a merit of providing the table menu and the nutritional diagnosis in that it can show the suggested amount of nutrition, the evaluation of nutrition, the methods of diet, and management of nutrition individually according to the age, sex, amount of exercise, and experience of sickness. The expected effect can be predicted to calculate the lacking amount of nutrition which the individual has taken, and be provided to the suitable table menu. In addition to this, the various table menu is based on the foods which can be purchased easily and inexpensively at any times.

본 논문은 형상의 비선형성을 고려한 큰 동하중을 받는 낮은 원호아치의 동적해석에 관한 연구이다. 따라서 낮은 원호아치를 대상으로 동적 비선형 해석을 수행하고 임계좌굴하중을 구할 수 있는 컴퓨터 프로그램을 개발하는데 주안점을 둔다. 형상의 비선형성은 Lagrangian 운동좌표를 고려하여 해석하였으며 비선형 동적 운동방정식을 풀기 위하여 유한요소법을 사용하였다. 개발된 프로그램을 사용하여 만재 방사형 등분포하중을 받는 원호아치를 해석하고, 그 결과를 다른 연구결과와 비교하여 검증하였다. 또한 여러가지의 형상의 아치에 대한 좌굴 해석을 실시하여 임계좌굴하중을 구하였으며 기존의 연구와 비교하여 정확성을 확인하였다. 모형해석을 통해서 큰 동하중을 받는 원호아치는 기하학적 비선형 거동을 고려하여 해석되어야 하며 아치가 낮아질수록 좌굴발생 가능성이 높아짐을 알 수 있다.

We developed a real-time CCD photometric program for IBM PC compatibles. This program can perform several functions necessary for CCD photometry such as telescope control. filter rotation, CCD camera control and data acquisition, two-dimensional image processing, simple aperture photometry and automatic differential photometry. The image processing of a spiral galaxy M51 observed with the SNU 61cm reflector shows a well developed spiral structure. Simple aperture photometric results of 14 stars in open cluster NGC 6871 almost accorded with those from IRAF/APPHOT. And we could confirm the light variation of eclipsing binary EM Cep by simultaneous automatic differential photometry of 7stars in NGC 7160. Due to the excellence in the precision and efficiency of automatic differential photometry using CCD. this program is very useful for the study of small amplitude δ δ Sct type variables and of the photometric stability of B ∼ ∼ F type stars.

The purpose of this study was to develop a computer-assisted patients menu planning program for hospital dietetics in order to improve the quality of menu for patients and to release managers from repetitive and routine tasks. Using this program, dietitians can spend more time on professional tasks. Moreover, few studies have been done on computer assisted patients menu planning for patients who need special diets for treatment in domestic hospital dietetics, therefore this program could be a great contribution. A 16-bit personal computer compatible with IBM-PC/AT was used. The data base files and processing program were created by Clipper package ver 5.0. This system can collect a number of meals, plan patients menu and computerize nutrient analysis. The future study will develop program(s) for purchasing, inventory control and data correction. The contents of computerized system are summarized as follows. 1. The number of daily meals of special and general diets given to the patients are collected and saved in database. These data were for the monthly list of meal census which could be printed out on the screen and/or the printer. 2. The menu planning was largely consisted of 2 sections. One was for the patients who require special diets and the other was general diet. And the special diets was divided into 6 sub-sections: diabetic, low-salt, low-fat, low-salt/low-protein, low-fat/low-cholesterol and low residue diets. 3. The nutrient analysis was composed of 11 diet. Sections and diebetic diet was divided into 9 sub-sections according to the calorie requirement. The calculated results were compared with the standards which were established by the hospital dietetic department.

The purpose of this study was to develop nutrition education program that promotes eating behavior of preschool children. 118 parents of preschool children were surveyed to understand of children's food preferences and prejudices. The preference for vegetable showed the lowest score(2.345) and fruit was the favorite food(4.11). These results imply the consequence of teaching balanced diet with emphasizing vegetables for preschoolers. Thus, nutrition education program including teaching material were developed to provide the preschoolers with cognitive, affective, and psychomotor activities in order them to the familiar with vegetables. The program were consisted of following five parts: 1. Read-A-Story includes six stories with follow-up activities. 2. Grow-A-Plant gives instructions for growing vegetables. 3. Play-A-Game stimulates children's imagination and learning. 4. Take-A-Trip suggests places to visit that grow, sell, and prepare vegetables. 5. Eat-A-Treat presents easy ways to prepare and enjoy vegetables. Twenty one-Standardized recipes for vegetable dishes were also developed for preschooler's luncheon and snack in daycare center.

The purpose of this study was to assess the nutrition education and training needs as a basis for program planning for day care children. Nutrition achievement test developed by American National Dairy Council and Iowa state University was modified and used for measuring the level of basic knowledge of food and nutrition for day care children. The results of this study can be summarized as follows 1. Over 70% of mothers indicated their children had a certain degree of food behavior and feeding problems in terms of unbalanced food habit, irregular meal period. 2. Mean score for the nutrition achievement test for day care children was 9.3. 3. The nutrition achievement test score for children with high socio-economic status was significantly higher than those of children with middle and lower group. 4. Inspection of the difficulty difference indices showed that over the 50% of the children had more items that were easier in the content of physiological facts than in the food handling and social psychological aspects of foods.

본 연구에서는 C++언어를 이용한 객체지향 프로그래밍 기법으로 매트릭스 연산과 평면뼈대 구조물의 해석이 가능한 PC용 구조해석 프로그램을 개발하였다. 객체지향 프로그래밍에서의 주요 개념인 객체, 클래스, 처리방식, 상속성 및 다형성을 도식화하여 설명하였으며, 매트릭스 연산과 평면뼈대 구조해석에 대한 예제 해석 결과는 이 프로그램의 효율성과 타당성을 보여 주었다. 따라서 본 연구는 객체지향 프로그래밍기법의 특징인 프로그램의 확장성과 재사용성 및 다양한 GUI의 구현가능성을 이용하여 앞으로의 객체지향 유한요소 프로그램 개발에 활용될 것이다.

The purpose of the study was to develop computer-based menu planning program for day-care centers maximizing food preference score among children and satisfying such constraints as expense, nutrients, and season. Children's preference about 142 menu items was surveyed among 382 children of day-care centers. A 16-bit personal computer compatible with IBM-PC/AT was used. The data base files were created by dBASE III Plus, and processing programs were created by using FORTRAN language. Children preferred bread or a la carte menu items to cooked rice in main dish category. Deep fat fried or stir-fried menu items were more preferred than kimchi or cooked vegetables in side dish category. Preference scores for menu items were influenced by cooking methods or main ingredients. The contents of the computerized system show that when the program runs, the user should type inputs of cycle, season, and menu pattern, then the computer lists a series of menu satisfying the criteria of constraints. The user can examine and select a set of menu from the menu lists. Menus are generated seasonally. Menu lists are generated weekly and monthly basis with the contents of menu items, preference scores and price. Nutrient reports are also generated on a weekly and monthly basis with the contents of calories, 12 nutrients and price. Recipes for each menu items are also generated.
