This study was conducted to find the effect of in-class nutrition education and exercise program for obese adolescent boys in Taegu with the nutrition knowledge test before and after education program and anthropometric measurement. The subjects were consisted of a normal group (NG; n= 13) and an obese group (n=30). The obese group is divided into two groups; obese group A (OG-A; n=12), participated in a ten-week nutrition education only; and obese group B (OG-B; n=28), participated in a ten-week nutrition education and exercise program. The anthropometric data of the three groups were increased after the nutrition education program. However the obesity index(BMI, R hrer, WHR, Skinfold thickness) of OG-B were significantly decreased after the programs. The nutrition intake data were also changed after the nutrition education program. Especially the intake of carbohydrate was significantly decreased in OG-B from 421.5±155.9g to 349.0±41.0g (p〈0.05) after the nutrition education program. It was noted that the intake of Ca was significantly decreased in all three groups after the nutrition education program. The mean score of the nutrition knowledge test also significantly increased from 13.7±3.1 to 17.8±3.0 after the nutrition education program. The result strongly suggested that nutrition education program should be successful if the obese adolescents and their parents especially mothers participated in the same class. In summary, nutrition education and exercise programs were effective on reducing obesity of obese adolescents. Nutrition knowledge of obese adolescent was significantly increased after nutrition education program.

Purpose: The research was to investigate the effect of line dance programs on oxygen saturation level and happiness of elderlies. Methods: Researchers had conducted a series of test to measure peripheral blood vessel oxygen saturation level, pulse and happiness level of 47 elderlies from the D district of G city. Collected data were analyzed with -test and independent t-test, equipped with SPSS WIN 17.0. Results: As a result of serial tests, Pre-test and Post-test of line dance performance showed that oxygen saturation of the Experimental group had significant increase following the program and happiness of the Experimental group also had significant increase following the program. Conclusion: In conclusion, with many advantages such as its easiness to access and emulate as well as its ubiquitousness as an aerobic exercise, line dance cannot only be very beneficial to cardiovascular function and relation of elderlies, but also to emotional and psychological effect, considered as a great breakthrough to improve comprehensive well-being in both physical and mental aspects.

The purposes of this research were to understand the realities of health management and to analyze the subjective, functional, psychological, and social health effects of the application of an exercise and education program to manage health on an elderly population residing in an agricultural community. The specific purposes of this research were: 1. to determine the subjective, functional, psychological health conditions, and performance level of instrumental activities of daily living of both the experimental and control groups before introducing a health management program, and then 2. to compare these with both the experimental and control groups' subjective, functional, psychological health condition and performance level of instrumental activities of daily living after applying the health management program. The health management program was introduced to the experimental group (50 people) but not to the control group (50 people). The health management program was composed of a health exercise program and a health education program. A comparative study of subjective health conditions was done to examine the effect of the health management program and the characteristics of health related variables before and after the program application. The results were as follows: 1. When the experimental group, which had received the 8-week health management exercise and education program, was compared with the control group, which had not, the experimental group's subjective health condition scored higher than that of the control group (p

본 논문에서는 가압열충격의 파괴역학적 해석에 필요한 이론을 조사하였고 원자로용기의 구조건전성을 평가하기 위하여 해석과정을 전산화하였다. 우선 사고 transient에 대하여 원자로용기내의 압력과 주입되는 냉각재의 온도변화가 주어지면 이들로 부터 시간에 따른 용기에서의 온도와 응력분포를 구하고, 중성자 조사량과 용기 재질의 화학성분으로 부터 기준무연성천이온도의 분포가 구해지며 이로부터 파괴인성치 KIA와 KIC의 분포가 얻어진다. 또한 응력분포로 부터 균열의 크기 및 형상에 따라 응력확대계수 KI이 구해지므로 이를 KIA및 KIC와 비교함으로써 균열의 성장거동을 예측할 수 있다. 지금까지 보고된 가압열충격을 유발할 수 있는 대표적인 사고 transient가 국내 발전소에 발생할 경우를 가정하여 해석을 수행하였고 그 결과에 대하여 검토하였다.

This study was carried out to develop the computer-assisted Hazard Analysis and Critical Control Point (HACCP) program for a systematic approach to the identification, assessment and control of hazards for foodservice manager to assure the microbiological quality of food in hospital foodservice operations. Sanitation practices were surveyed and analyzed in the dietetic department of 4 hospitals. Among them, one 762-bed general hospital was selected as standard model to develop computer-assisted HACCP program. All data base files and processing programs were created by using Foxpro package for easy access of HACCP concept. HACCP program was developed based on the methods suggested by NACMCF, IAMFES and Bryan. This program consisted of two parts: the pre-stage for HACCP study and the implementation stage of the HACCP system. 1. Pre-stage for HACCP study includes the selection of menu item, the development of the HACCP recipe, the construction of a product flow diagram, and printing the HACCP recipe and a product flow diagram. A menu item for HACCP study can be selected from the menu item lists classified by cooking methods. HACCP recipe includes ingredients, their amount and cooking procedure. A flow diagram is constructed based on the HACCP recipe. The HACCP recipe and a product flow diagram are printed out. 2. Implementation of HACCP study includes the identification of microbiological hazards, the determination of critical control points, the establishment of control methods of each hazard, and the complementation of data base file. Potentially hazardous ingredients are determined and microbiological hazards are identified in each phase of the product flow. Critical control points (CCPs) are identified by applying CCP decision trees for ingredients and each process stage. After hazards and CCPs are identified, criteria, monitoring system, corrective action plan, record-keeping system and verification methods are established. When the HACCP study is complemented, HACCP study result forms are printed out. HACCP data base file can be either added, corrected or deleted.

We have developed a graphic software for image processing of astronomical data obtained by observational equipment in Astronomical Observatory of Kyung Hee University. The essential hardware for running our computer program is simply composed of a PC with the graphic card to handle 256 colors and the color graphic monitor, including CCD camera system. Our software has been programmed in WINDOWS to provide good environments for users, by using various techniques of image processing on astronomical image data recorded in FITS format by KHCCD program(Jin and Kim, 1994) with a compressional mode. We are convinced that our results will be a fundamental and useful technique in the construction of data processing system and can be effectively used in any other observatories, as well as in data processing system of Kyung Hee University.
