The study empirically investigates financial factors that may influence on corporate R&D intensity during the post-era of the global financial turmoil (from 2010 to 2015) to mitigate possible spillover effect associated with the crisis. Concerning the empirical research settings of the study, chaebol firms listed in the KOSPI stock market are used as sample data with adopting various econometric estimation methods to enhance validity of the results. In the first hypothesis test, it is found that there exist inter-industry financial differences in terms of the ratio of R&D expenditure across all the sample years, but the statistical differences may arise from only a few domestic industries beloning to the high-growth sector. Moreover, it is also interesting to identify that, for the high-tech sector, 3 explanatory variables such as R&D intensity in a prior year, firm size and change in cash holdings are proved to be financial factors to discriminate between chaebol firms and their counterparts of non-chaebol firms, whereas a proportion of tangible assets over total assets as well as the former two variables are shown to be significant factors on the R&D intensity for the low-tech sector.

In many countries, such as developing countries where electricity is scarce, small wind turbines in the form of Off Grid are an effective solution to solve power supply problems. In some countries, the expansion of power systems and the decline of electricity-intensive areas have led to the use of small wind power in urban road lighting, mobile communications base stations, aquaculture and seawater desalination. With this change, the size of the small wind power industry is expected to have greater potential than large-scale wind power. In the case of small wind power generators, the generator is controlled at a variable speed, and the voltage and current generated by the generator have many harmonic components. To solve this problem, the AC to DC converter to be studied in this paper is a three-phase step-up type converter with a single switch. The inductor current is controlled in discontinuous mode, and has a characteristic of having a unit power factor by eliminating the harmonic of the input current. The proposed converter is composed of LCL filter and three phase rectification boost converter at the input stage and a single phase full bridge for grid connection. It is a control system with energy storage system(ESS) that the system stabilization can be pursued against the electric power.

In this study, we examine the concept of social value which is the main philosophical foundation in government innovation pursued by Moon Jae-In government and analyze the case of government innovation which was promoted by specific local governments. The purpose of this study is to discuss the implications for the government innovation through the case study of local autonomous organizations. The studied local government is an institution that has received excellent evaluation of government innovation for the realization of social value by Ministry of Public Administration and Security. In this study, we conducted in-depth interviews with local governments and youths and examined the success factors of government innovation through active participation in community issues. First of all, institutional support such as ordinances is important for encouraging the participation of community members. It is also important for local governments to lead their own change and listen to their voices from a consumer perspective, not from a supplier perspective. In addition, significant importance of the incentive system that could induce continuous participation in community problems was found. In this way, it is possible to establish a continuous system to approach the problem of local community as consumer perspective, not supplier perspective, and solve the problem together.

The purpose of this study is to investigate the experience of the mother-daughter relationship among middle-aged women in depth through the process of admission to nursing home facilities of their dementia mother. For the purpose, 8 middle-aged women whose dementia mothers were admitted to nursing care facilities were selected as research subject, and data collection was carried out through individual interviews. As a result of this research based on the phenomenological method of Colazzi, 3 categories, 6 sub-categories, and 17 subject bundles were derived. Research results can be summarized as follows: First, the mother-daughter relationship was dramatically reversed in the process of mother's admission to the nursing care facilities. Second, in the process of dementia mother's admission to the nursing care facilities, it was confirmed that daughters rather than sons were in an independent position regarding care and management. Third, in the process of dementia mother's admission to the nursing care facilities, it turned out that the entire family experiences depression, anxiety, and feeling of loss due to a sudden change in mother-daughter relationship as well as further transformation in family relationship, suggesting that there is a need to operate education or consultation programs for the family members to help them accommodate and deal with the sudden change.

The aim of this study was to investigate the short term effects of early intervention on alcohol knowledge, alcohol expectancies, drinking refusal self-efficacy for alcoholism prevention in adults and to examine its applicability in the field. This study was a non-equivalent control group pre-post quasi-experimental design. The participants were currently working, and were 12-25 points on result of the Alcohol Use Disorders Identification Test(AUDIT). The participants were a total of 25 men: 13 in the intervention group and 12 in the control group. The intervention group participated in early intervention program once a week for 4 weeks and the control group received only a booklet of alcohol related information. A chi-square test, t-test, Mann-Whitney U test were analyzed by using IBM SPSS Statistics 20.0. The intervention group had significantly higher the alcohol knowledge(t=1.258, p= .002), the negative alcohol expectancies(t=-1.346, p= .042), and the drinking refusal self-efficacy(t=2.817, p= .010) than the control group. In the future, it is need to apply the criteria of problem drinkers considering cultural characteristics, recruitment of participants, and motivational enhancement intervention using motivational interviewing. Especially, web-based alcohol related information providing program will help raise awareness of problem drinking. Early intervention program needs to be applied in community settings where problem drinkers are easily accessible.
