  • In this study, the researcher tried to present the groundwork to prepare the oriental medical yangseng plan for the future obesity with the comparison between yangseng level and the obesity of workers. The researcher made up the questionnaire which asks the general character, health-related character and yangseng level, projected among 560 people. All collected material was analyzed by SPSS and tested by T-test and ANOVA. 1. The general yangseng level average is 3.27, morality yangseng 3.90, sleep yangseng 3.39, mind yangseng 3.31, sex life yangseng 3.30, exercise yangseng 3.15, activities and rest yangseng 3.08, diet yangseng 2.94, seasonal yangseng 2.84. The highest is morality yangseng and seasonal yangseng is the lowest. 2. In the aspect of yangseng level: Having a spouse, Non-smoking, Regular exercising, Sufficient sleeping have higher yangseng levels. 3. Obesity related index is changing into the higher level when he/she is older, more paid, more job experience, more education background but less metabolic calory. And drinking and regular exercising have relativity with body composition analysis. 4. After comparing yangseng level with body composition analysis, we can easily find that the more visceral fat, the higher WHR has a high yangseng level. The more mineral also has a high mind yangseng and a low diet yangseng. The visceral fat level has a high yangseng level when higher morality yangseng and mind yangseng are getting higher and higher. And sex life yangseng shows that the highest yangseng level is from 9-10 visceral fat and the lowest yangseng level is from below 4 visceral fat. The higher WHR, the higher morality, mind and sleep yangseng. The heavier, the lower diet yangseng. The mind yangseng was very high when body fat rate was higher. The more body fat, the higher morality yangseng. The higher yangseng, when we have more muscle. Yangseng level and obesity of laborer has a close relationship with individual character and daily habits. Also, relevance can be easily found between yangseng level and obesity. Now the researcher came into the conclusion that we need to control over laborers' health and prevention of their obesity.

  • After 1990's, many multi-level marketing companies lave been introduced in Korea. These MLM companies operate their stores as same way as general retailing stores. The major characteristics of these MLM companys' store is that their main customers are distributors who sell the purchased merchandise to another customers. Many studies about merchandise display in general retailing stores were reported. But, there was less research about merchandise display in these special type stores such as MLM companys' stores. This paper investigates the effects of merchandise display on distributor's merchandise selection in channel flow of multi-level marketing company. For this purpose, we formulated four hypotheses about display variance in quantity, height, location, and related merchandise to analyze the effect of merchandise display methods in MLM companys' stores. The experiment had been proceeded in three stores in a MLM company for 6 weeks and the sales data were collected by POS. The methods to analyze the data were used ANOVA and T-test. Findings of this study are as follows; First, there was no effect to store sale by the interaction effect between merchandise display method and scale of store. Second, scale of store affected considerably the volume of sales of each store according to main effect analysis. Third, display variance in quantity, height, and location did not affect store sale. In the related merchandise display, however, sale in all store was increased. Fourth, in additional analysis considering merchandise display only, display variance in both height and location affected their sale in large scale store. Based on the above results, we may predict merchandise display can affect sale in MLM companys' store as well as general retailing stores. Therefore if MLM company has large scale store, it should consider merchandise display methods in its stores.

  • A purpose of the object-oriented programming is to promote reuse and development time, and to improve software quality. A way for this purpose is using a design information well-defined and tested in previous time when developing software. Such design information is called design patterns. The design patterns are descriptions of abstract solution to recurse software design problems In a systematic and general way. But because the design patterns are descriptions of abstract solution, the specification and application of patterns generally rely on manual implementation and is applied to various forms. As a result, we need to spend a lot of time to develop software program not only because of difficulty in analyzing and applying to patterns consistently, but also because of the frequent programing faults. And because the applied design patterns don't express inside application visually, it is difficult to analyze and test for this design patterns. In this paper, we propose automatic source code generating technique to be able to efficiently apply the element of design patterns when developing application. And we show a way to analyze and use the applied design patterns in application. As a result, the design patterns in application provide the consistent structure and efficiency, and make analysis and using effect increased.

  • This paper deals with the analysis and comparison between on the course of a conventional engineering design (typically project-based learning) and a new engineering design (introduced PBL model to conventional engineering design). The purpose of the study is to identify and prove the effect of PBL model on the course with a new teaching-learning. In the result of t-test, there were significant statistics in the creative problem solving and self-directed learning ability, but no significant statistics in the team work and communication skill ability. Also the average of factors of the problem-based strategy is higher than those of the project-based strategy. In the problem-based strategy, the team work has the most influential on the satisfactory of the course. However in the project-based strategy, the comprehension of given product has the most influential on the satisfactory. Finally, this study has proved the effect of PBL on the course engineering design.
