The purposes of this study were to review the rural youth programs of selected foreign countries and to draw some implications to the rural youth programs in Korea. The youth development programs reviewed were 4-H Youth Development Program of U.S.A, Rural Youth Information Service of Australia, Rural Youth Job Strategy of Canada, The Urban-Rural Youth Program of U.S.A, and Expert Consultation on Extension Rural Youth Programmes and Sustainable Development of FAO. After reviewing the rural youth programs of selected foreign countries, the authors suggested the following implications for further development of rural youth programs in Korea; 1. The target group of rural youth programs should include urban youth as well as rural youth, and the programs should be focused on enlarging their awareness of the rural community and agriculture. 2. Rural youth programs should be extended beyond agricultural sectors, such as leadership, career development, leisure activity, and cultural life. 3. We should develop some programs to support academic achievement, career development, employment, cultural needs including some strategies to prevent problematic behaviors of rural youth. 4. Rural youth should be supported more opportunities to join the community life to experience and learn various life skills through active participation such as interpersonal skill, leadership skill, and problem-solving skill.

Purpose: This study was performed to determine the effect of drinking prevention program on the levels of drinking related knowledge, attitude, drinking refusal self-efficacy and behavior of vocational high school girls. Methods: Pre-post test design. The subject was used for a group of high school girls. The data were collected on May and September, 2006 and June, 2007 and analyzed using paired t-test. Results: The drinking-related knowledge score after one year was significantly higher than that of pretest (t=-14.02, p=.001) and the drinking-related attitude score was lower (t=2.85, p=.006). The drinking refusal self-efficacy and the drinking behavior measured as number of drinking events, amount of alcohol and number of heavy drinking events were not significantly different between pretest and post test after one year. Conclusion: Drinking prevention program should be given to increase the drinking refusal self-efficacy and decrease or prevent the drinking behavior of high school girls every semester at least.

Flow mismatch between blood and dialysate is invariably encountered during conventional hemodialysis, and this deteriorates diffusive mass transfer. A modification of a conventional dialyzer was conceived to prevent this mismatch. The modified dialyzer includes two independent blood flow regions (central and peripheral regions), which were achieved by redesigning the dialyzer cap. Resultantly, the blood stream was divided into two concentric dialyzer regions. Solutes clearances obtained using the modified dialyzers were compared with those of conventional dialyzers. Solutes clearances by conventional dialyzers were uniform, but solutes clearances by modified dialyzers were found to be dependent on the simulated blood split into dialyzer central and peripheral regions. Maximal clearances using the modified dialyzer were improved by up to approximately 7.6% for urea and 7.3% for creatinine, as compared with those of conventional dialyzers. More optimizations are required for clinical applications, but the finding that blood flowrates through central and peripheral fiber bundles can be easily regulated is encouraging.

The purpose of this study is to identify the effective lumbar area exercise program to prevent falls of the elderly by dividing 14 female elders over 65 living in Daegu into two groups such as resistance exercise group and resistance & stabilization exercise group, and applying a 60 minute exercise program three times a week for 12 weeks. The followings are the results. First, both of resistance exercise and resistance & stabilization exercise brought improvement of lumbar strength and there was no significant difference between two groups. Second, there was no significant difference in lower limb strength in resistance exercise group but resistance & stabilization exercise group showed significant increase in lower limb flexor strength. To make a summary of the above results, it can be said that 12 weeks' resistance & stabilization exercise is effective to the lumbar strength and lower limb strength of the elderly. Accordingly, if combining resistance exercise and stabilization exercise appropriately, we can build a successful preventive program which even the elderly who cannot perform resistance exercise easily can follow.

Purpose: This study was to identify the effects of the predictive factors of Internet addiction and to develop a predictive model that explains Internet addiction among adolescents in Korea. Method: Data was collected from 664 adolescents in Puasan and Ulsan. Data analysis was done using the SPSS 10.0 Win Program for descriptive and correlational statistics and the LISREL 8.53 Win Program for Covariance structural analysis. Result: The fit of the hypothetical model to the data was moderate, it was modified by deleting four paths. Compared to the hypothetical model, the revised one had a better fit to the data($\chi^2$/df=6.50, GFI=.99, AGFI=.90, RMR=.02, NNFI=.88, NFI=.98, CN=279). Gender, friend support, and loneliness had significant direct effects on Internet addiction. The direct and indirect effect of self-esteem on Internet addiction was significant. The indirect effect of family support on Internet addiction was significant but its direct effect was insignificant. The direct and indirect effects of stress and impulsiveness on Internet addiction were significant but their total effects were insignificant. Conclusion: Finally, to decrease loneliness, and to increase family support and self-esteem, an effective intervention program and education should be developed to prevent Internet addiction of adolescents.

Online cybercrime has various causes. The criminal guilty language, Criminal lingo is active in the shaded area with the bilateral aspect of the word on cyber. It has been continuously producing massive risk factors in cyberspace. Criminals are shared and disseminated online. It has been linked with fake news and aids to suicide that has recently become an issue. Thus the criminal lingo has become a real danger factor on cyber interface. Recently, Criminal lingo is shared and distributed as cyber hazard information. It is transformed that damaging to the youth and ordinary people through the internet and social networks. In order to take action, it is necessary to construct an expert system based on AI to implement a smart management architecture with block-chain technology. In this paper, we study technically a new smart management architecture which uses artificial intelligence based decision algorithm and block-chain tracking technology to prevent the spread of criminal lingo factors in the evolving cyber world. In addition, through the off-line regular patrol program of police units, we proposed the conversion of online regular patrol program for "cyber harem area".

In the high carbon steel wire drawing process, the wire temperature increases as the drawing speed is faster in order to increase the production rate in the shop floor. The rapid temperature rise causes the wire fracture in the dry wire drawing process. So, in this paper, the isothermal pass schedule program, which includes the calculation method of wire temperature at each pass, is proposed to prevent the wire fracture due to the temperature rise. Using the isothermal pass schedule program, it is newly proposed the pass schedule design system that prevents the cup-cone defects, improves the elongation of the final products and assures further deformation. As a result, the temperature rise of the wire was decreased and the production rate of the final product is remarkably grown up according to the increase of the final drawing speed than that of the conventional process. Also, the proposed pass schedule design system could give a useful information to the process designer who would design the high carbon steel wire drawing process.

Most consumers have experienced unexpected consumer problems in the new consumption environment. Accordingly consumer education is very important to prevent consumer problems in advance. Adult consumers don't have many chances to take consumer education with various reasons though they are in a core position in the economy. This study developed an on-line consumer education program for adults in consumerism in the website, www.bestmaker.com/cw. The contents of consumerism were divided into five subfields such as consumer rights, responsibility and roles; consumer law; consumer participation; consumer protection; on-line survey. The on-line consumer education program was given to 164 adult consumers who could use internet, and the contents and the methods of the consumer education were evaluated by the same consumers with an on-line survey. The results of the survey show that those in 30's through 40's and with higher education are more satisfied with the contents and the methods of the on-line consumer education. This study implies that the contents, the methods, and the design of an on-line consumer education need to be consistent each other and well organized altogether.
