This study was carried out to evaluate the relations among working environments, health behaviors and satisfaction with their duty in a group of 200 ship-repair workers in the ROK navy. The results were as following; Age of workers was 40 years and over(83%) and working duration was 10 years and over (71.5%). Most of them were married and had studied beyond high school. The 69.5% of workers satisfied with their job, whereas. about 59.5% of workers had satisfaction with their working condition. There were current drinkers, 78.5%, current exercising workers, 43.5%, obese workers, 28.0%, and salted food intakers, 18.5% in the workers. The major harmful environmental factors in the ship-repair workplace are noise, vibration, dust and chemicals. Most of workers are exposed to above harmful factors and complained about exposure of noise and dust. The consumption of cigarette or alcohol in people who exposed to noise was much higher than in people who did not, but the difference was not statistically significant. Prevalence of obesity and hypertension were not significantly different between the exposure with noise and dust. Noise or dust exposure was significant relation to satisfaction with their duty and working condition. The affective factors for satisfaction with their duty were people who worked for 10 years or more(OR= 4.53), exercisers(OR=4.78) and dust(OR=3.05) in Logistic regression analysis.

Purpose of this study was to identify influence of barrier to course of life and ambition on decision level of life course and to provide the result to dance major students to help analysing mental, sociological and environmental problems which could be faced with course of life. By using Straified cluster random sampling, 300 university students who major the dance were sampled as subjects through Choonnam, Daejeon and Gangwon area. Questionnaire data were obtained from all subjects by self-administration method, and 291(90.18%) out of 300 cases were used as valid samples. Results of the analysis could be summarized as the following. First, How did barrier to course of life influence to decision level of life course? Influence of skeptical level presented difference that no plan barrier was 0.1%, economic barrier was 1%, circumstance barrier was 5%. Negative level presented difference that no plan barrier and sexual discrimination were 0.1%, negative barrier of workplace was 1%, circumstance barrier were 5%. In the case of helping need level, difference presented that economic barrier was 5% and only factor. Influence to decided level presented difference only in no plan barrier at 5% level. Secondly, How did ambition influence to decision level of life course? Influence of skeptical level presented that no effort ambition was 0.1% and lead ambition was 5%. Negative level presented difference that no effort ambition was only and 0.1%. In the case of helping need level and decided level presented no difference. Third, What are difference of ambition of life course between the major and grade of the sample? Social dance major compared to Korea dance presented high scale in non - endeavor ambition. In the case of Endeavor, Korea dance major presented high scale compare to social dance. Difference of ambition of life course presented higher on 3rd grade than 1,4 grade students.

에이전트 기반의 맞춤형 교육 시스템

김은경,허선영 한국기술교육대학교 2006 論文集 Vol.12 No.1

According to the rapid popularization of the internet, recently the number of web-based remote education systems are rapidly increased. And demand for the customized educational service suitable for individual learner's level and learning pattern is increasing. Meanwhile, most remote education systems do not provide adequately customized educational service fit for each learner's level and lots of learners easily lose their interest in studying. Therefore, many researchers have used agents to provide personalized educational service by analyzing learner's level and learning pattern automatically. In this paper, we designed and implemented an agent-based customized education system(ACE) for individual learning. ACE tries to provide more suitable and individually customized learning contents by dividing learners' level into 5 stages and reproduces new learning contents on section unit instead of chapter unit. Also, ACE encourages learners' participation by providing proper feedback and sending e-mails including each learner's studying stage and learning target regularly.

In this study, open type wind tunnel has been restructured instead air blower. its designed and fabricated part are diffuser. settling chamber with screen, contraction or nozzle, and test section. Also inverter enable to control variable speeds. And basic experiments have been performed to check the flow characteristics for restructured open type wind tunnel. In these procedures, we have got some conclusion. the control of contraction is valid for X = 0.40 considering Morel's and Fang's suggestion. it is confirmed that the two pressure coefficients for avoiding separation is satisfied with Fang's result. Distribution of uniform velocity in test section are stabilized above 95~99%.
