In this study, thirteen villages in Chonnam province were selected as case study sites and the spatial distribution of the facilities in the villages was examined to provide basic information fur the establishment of rural plans. According to the questionnaire survey, various problem such as environmental pollution, position, scene, management etc. was brought owing to cattle shed, and dissension was more or less seen by scale of facilities, management of facilities and waste, regional factor(stock farming management condition, life style and attitude of inhabitants) and topographical factor (height, position physical aspect of a mountain, distance with water resources etc.) etc.. The facilities could be classified into 6 types based on the their spatial locations: 1) Type 1, facilities located at the waterside; 2) Type 2, facilities located at the entrance of village; 3) Type 3 facilities, scattered in the residential area: 4) Type 4 facilities, collectivized in village; 5) Type 5 facilities, adjoining village; and 6) Type 6 facilities, scattered irregularly inside and outside of village. Based on the classification, possible implementations for the reduction of environmental impacts were suggested. The results of this study could be used as an example of study on the distribution, classification, and rearrangement of environment-impacting facilities in rural areas for improvement of their roles in providing amenity resources.

By investigating structural relationships between personal image and self-efficacy, this experimental study purposes to suggest a direction and the meaning of effective education on personal image. Based on scholars' studies on personal image and self-efficacy, this study extracts a revised questionnaire on personal image. The experimental study proved the relationship between the variables of personal image and self-efficacy by using personal image questionnaires which are extracted from the literature study. For this purpose, we have conducted a questionnaire survey including 234 students from women's university in Seoul. The results of this study are as follows. First, for cognitions on personal image, which are components of the internal image, both the visual image and social image impacting on self-efficacy have a significant efficacy in the self-regulation factor. Second, the satisfaction rates of the components for personal image impacting all the factors of self-efficacy showed a significant effect. Third, the significant results are being obtained from the analysis of differences in self-efficacy according to the levels of satisfaction rates on internal image and social image, which are expected to have effects on the self-efficacy between the groups for all factors. However, according to the analysis of differences in self-efficacy in relation to the levels of satisfaction for visual images, only the self-confidence factor in the self-efficacy is different between the groups.

Disputes seem to be synonymous with large-scale construction projects in Ethiopia. The purpose of this study is to determine the factors responsible for impacting the performance of Ethiopian public construction projects. To this end, 35 success and failure attributes responsible for impacting the performance of the projects were identified and presented to Ethiopian construction professionals in the form of a structured questionnaire, and responses were collected. The factor analysis conducted on the success and failure attributes influencing no-dispute performance separately resulted in six success factors and five failure factors. Further analysis using stepwise multiple regression indicates that owner competence and interaction among project participants have a positive impact on no-dispute performance. However, conflict among project participants has a negative impact on the no-dispute performance of Ethiopian public construction projects. Although Ethiopia-specific, the results reflect construction management problems common to both developed and developing countries. The findings are expected to help researchers and practitioners gain a better understanding of critical success and failure factors and to help them take proactive measures to avoid disputes in public construction projects.

This paper provides a method to evaluate the competitiveness based on IT innovativeness considering the adoption phase and shows how to apply the method with a case of foreign market in the early-adoptive phase. The proposed method considers a variety of corporate and market characteristics concerned with the technology adoption, and it consists of several internal and external impacting factors that can influence the level of IT diffusion. Main advantage of this method is the ease of its applicability that allows evaluating the innovativeness, regardless of corporate size, industry type, or level of technology adoption. Therefore, it is possible for this method to evaluate the technology competitiveness easily and repeatedly, in terms of IT innovativeness by inter-organizations and inter-nations. For the case analysis, the Mongolian IT market with several Korean IT joint firms is introduced, and final data resulted from an early-adoptive phase case are analyzed.

Atmospheric pressure plasma polishing (APPP) is a noncontact precision machining technology that uses low temperature plasma chemical reactions to perform atom-scale material removal. APPP is a complicated process, which is affected by many factors. Through a preliminary theoretical analysis and simulation, we confirmed that some of the key factors are the radio frequency (RF) power, the working distance, and the gas ratio. We studied the influence of the RF power and gas ratio on the removal rate using atomic emission spectroscopy, and determined the removal profiles in actual operation using a commercial form talysurf. The experimental results agreed closely with the theoretical simulations and confirmed the effect of the working distance. Finally, we determined the element compositions of the machined surfaces under different gas ratios using X-ray photoelectron spectroscopy to study the influence of the gas ratio in more detail. We achieved a surface roughness of Ra 0.6 nm on silicon wafers with a peak removal rate of approximately 32 $mm^{3}$/min.

Objectives: The purposes of this study were to investigate the life satisfaction, obesity, depression, self esteem, body image of adolescents by their demographic characteristics, to analyze factors impacting on life satisfaction, and to provide basic data to intervention programs for bright and healthy development. Methods: The data in this study came from the Korea Youth Survey Data collected through questionnaires from 10,156 students. To investigate the causal relationship between each variable presented in the research model, descriptive statistics, t-test, ANOVA, Scheffe's test, correlation analysis, hierarchical regression analysis were carried out by using SPSS Ver. 18.0. Results: The most impacting factor on adolescents' life satisfaction were the self-esteem and depression, followed by the economic level, regular exercise, and regular eating. In conclusion, the strongest factors that influenced adolescents' life satisfaction were self-esteem and depression. Also we found that regular eating, regular exercise, and adequate sleep were the important causes of raising adolescents' life satisfaction. Conclusions: In order to enhance the adolescents' life satisfaction, we should make an effort to increase self-esteem, to prevent obesity, and to reduce depression through regular exercise and eating, adequate sleep. Therefore, it is important to recognize the importance of regular exercise and eating through health education. In addition, it is needed desperately to develop sleeping education program and to efforts to ensure sleeping right of adolescents.

Port in Northern Vietnam has been playing an important role in the logistics system the country. In recent years, the cargo throughput of the region, especially, containerized cargo has increased gradually. There are totally 11 container terminals in Northern Vietnam, concentrating in Haiphong city and Quang Ninh province. Despite of increasing demand, the competition among the terminals is becoming more and more critical. The paper, firstly, summarizes factors impacting the market share of the terminals before reveal the correlation between given factors and annual container throughput. Factor analysis will be then applied to evaluate the level of terminals' logistics infrastructure. For the conclusion, strategic thinking of terminals' logistics competitiveness will be contributed to related organizations.
