The indicators of an advanced society include the overall level of life quality and satisfaction among all the members. The overall life quality has close relationships with accessibility to urban space for the social weak. Access to facilities of interest and right of mobility in urban space are very important issues to the weak class in terms of transportation including the visually handicapped. In particular, great significance is endowed upon transfer facilities, which play mediating roles between facilities like passenger facilities, and the convenience facilities inside for the disabled, which are usually the only means for the disabled to access each facility. As they are provided to the visually handicapped as well, it's very important to analyze the concerned spatial distribution and offer the results. The previous studies on the subject, however, merely covered the perceptions of the users and the related statistical analysis. This study set out to analyze non-barrier space to promote the utilization of convenience facilities at passenger facilities by the visually handicapped and to secure their right of mobility by using a GIS for spatial analysis based on spatial data. The results show that it's urgent to supplement the existing space for the handicapped and that it's necessary to expand convenience facilities for the disabled such as paths with Braille points on them to promote their use of diverse convenience facilities inside.

The main purposes of this study are to describe regional differentials of the rate and to explore factors impacting on the regional differentials among the elderly's suicide rate in the Republic of Korea. Suicide data among 16 provinces from 2000 to 2008 were used for the statistical analyses. Six independent variables, such as crude divorce rate, GRDP per capita, welfare budget proportion, number of leisure facilities, number of medical and housing welfare facilities, and number of sports facilities are introduced for the multiple regression analyses. Elderly suicide rate, female elderly's suicide rate, and male elderly's suicide rate are used for the dependent variables. The findings of this study are as follows: Elderly's suicide rate has been increased constantly since 2000 and regional differentials of the elderly's suicide have been existed over time. According to the multiple regressions analyses, number of sports facilities(${\beta}$=-521), welfare budget proportion, and number of leisure facilities(${\beta}$=-219) have shown statistically significant negative relationships with the elderly's suicide rate. On the other hand, number of medical facilities(${\beta}$=0.550), crude divorce rate(${\beta}$=0336) have shown statistically significant positive relationships with the elderly's suicide rate in the Republic of Korea. Finally, some policy implications for alleviating the elderly's suicide rate are introduced and discussed.

This study aims to analyze whether both childcare subsidy and childcare leave policies have moderating effects on the relationship between Korean women's value of children and their intentions for subsequent childbirth. The data are used from the 2015 National Survey on Fertility and Family Health and Welfare. Both hierarchical multiple regression analysis and moderated regression analysis are used for statistical analysis. The findings from the study are as follow. First, the ideal number of children, instrumental values, and emotional values have positive effects on the intentions for subsequent childbirth after controlling for background variables(level of education, income, age, and number of children). Second, childcare leave policy has no significant effect on the intentions for subsequent childbirth while childcare subsidy policy has the negative effect. Third, only childcare subsidy policy has moderating effects on the relationship between instrumental, emotional values, and the intentions for subsequent childbirth. These results suggest that policies enhancing the value of children should be implemented in addition to traditional birth rate policies. Furthermore, new birth rate polices are needed for those married women who have a high possibility of subsequent childbirth.

Wearable computers can be defined as next generation clothing integrated with various digital functions and devices. Unlike existing computers, they are viewed as human-centric computers customized for information utilization and other specific human needs. This study is intended to discover how consumers are accepting wearable computers, which are different from existing computers, based on Technology Acceptance Model(TAM) and to extend the model by adding variable regarding acceptance of wearable computers. A total of 683 copies of questionnaires, distributed to those aged 19 and older, both male and female, were collected online. The data was statistically analyzed for this study using the extended TAM. In order to test hypotheses, the structural equation model using the Lisrel 8.30 version was performed. For analyzing constructs(or traits) of research model, exploratory factor was conducted and the measurement model was assessed from the result. Reliability was assessed through confirmatory factor analysis and the calculation of Cronbach's alpha coefficients. Overall, model fit was assessed by statistical indexes: Chi-square value, GFI, AGFI, and RMR. This study analyzed the process of acceptance of wearable computers with the extended TAM that includes a variable, perceived value, on the basis of previous studies. The results of the analysis revealed that attitude toward wearable computer was directly influenced by perceived usefulness and perceived value but indirectly influenced by perceived ease of use. Acceptance intention of the wearable computer was directly influenced by perceived value and attitude toward wearable computer. To be more specific, perceived usefulness was significantly correlated with both attitude toward wearable computer and acceptance intention of the wearable computer. Perceived value was also significantly correlated with both attitude toward wearable computer and acceptance intention of the wearable computer. The results of this study also suggested that perceived ease of use was actually a causal antecedent to perceived usefulness and perceived value. This research revealed that extended TAM to investigate the acceptance of wearable computer was appropriate. This study is intended to provide a theoretical framework for adoption of wearable computer and suggest empirical analysis that can serve as a guide for wearable computer.

This study aims to find some characteristics for the facilities of the 'Korea Forest Welfare for Life Cycle' through the domestic case analysis, so that we draw implications applicable to the policy on Korea Forest Welfare. For this, we brought and analyzed statistical data together from scattered sources. As the characteristics for the facilities of the Korea Forest Welfare for Life Cycle, first, there is the quantitative imbalance of forest welfare institutions for the each life cycle. Second, there is a lack of facilities in urban areas. Third, the facilities are mostly located in national or public forests. And, based on those characteristics, we suggest several things as follows that is applicable to the related policy. First, it is necessary to meet the needs of facilities that need to be built evenly for each life-cycle. Second, facilities of the Forest Welfare for Life Cycle which is adjacent to the life zone should be built more to increase accessibility. Third, forests in Korea are almost comprised of private forests. Using only national and public forests has an unfavorable condition to confer a benefits of forest welfare on the people evenly than using national, public and private forests all together. Therefore, there is a need to invigorate private capital and utilize private forests so that the favorable condition can be made to confer a benefits of forest welfare on the people evenly and adjust balance of the quantity for the facilities of forest welfare.

This study estimates the productivity change of pharmaceutical industry and decompose the change into technical efficiency change and technological change to explore ways to improve the productive efficiency. Unlike most previous studies, this study employs the non-radial and non-oriented slacks-based Malmquist productivity index which can deals directly with the input excesses and output shortfalls. In addition a smoothed bootstrap method is applied to estimate statistical confidence intervals for the Malmquist Index and its components. For the empirical analysis a balanced panel data set is constructed covering ten years over the period from 2005 to 2014. The input variables used in this study are number of workers, tangible assets and major production cost. The gross production is selected as a main output variable. The empirical results suggest that the productivity of pharmaceutical industry has decreased due mainly to decline in the technological progress rather than improvements in technical efficiency. An analysis result shows that the scale efficiency outweighs the pure efficiency in determining the technical efficiency of pharmaceutical industry. Therefore, in order to enhance the competitiveness of domestic pharmaceutical industry, it is important to continue supporting policies to promote the technology innovation capability through efficient R&D investment and industry reform strategy.

Objective: Human sperm nucleus DNA damage may negatively affect pregnancy outcome, and the spermatozoa of infertile men have more DNA damage than that of fertile men. The aim of this study was to evaluate the effect of microsurgical varicocelectomy on human sperm nucleus DNA integrity. Methods: We reviewed the medical records of 18 subfertile male patients who underwent microsurgical varicocelectomy at our hospital from April 2006 to April 2007. Varicocele was diagnosed by physical examination and Doppler ultrasound. Standard semen analysis was performed in 18 patients before and 4 months after microsurgical varicoceletcomy using a computer assisted semen analyzer. Sperm nucleus DNA integrity was assessed by a single-cell gel electrophoresis (comet assay). Results: No recurrence of varicocele was observed after 4 months later. The DNA fragmentation index improved after varicocelectomy compared with pre-operatively (19.3 versus 13.7%, respectively, p<0.05). Semen analysis parameters (total count, concentration, motile sperm, viability, strict morphology) increased after varicocelectomy, but the difference did not reach statistical significance. Conclusion: Our data suggest that microsurgical varicocelectomy can improve semen analysis parameters and human sperm nucleus DNA integrity in infertile men with varicocele.
