본 연구에서는 사회적으로 그 중요성이 점차 커지고 있는 교육기부와 관련하여 그 효과성을 분석하기 위한 정량적 분석 방법론을 연구하였다. 과거 국내에서 진행되어온 교육기부의 효과성 분석에 대한 연구들은 주로 설문조 사나 인터뷰를 통한 인식· 만족도 조사와 같은 정성적 분석에 치우쳐있으며, 이에 반하여 정량적 분석에 관한 연구는 그 진척이 상당히 느리다. 따라서 본 연구에서는 기부의 역사가 훨씬 오래된 미국과 영국에서 사용하고 있는 정량적 분석틀을 도입 하여 교육기부의 효과성을 정량적으로 분석하여 보았다. 특히 그 분석 프레임으로는 사회적 기업의 사회경제적 가치를 산정하기 위하여 개발된 SROI(social return on investment)의 개념을 교육기부에 맞게 적용하려는 시도를 하였으며, 이를 통해 교 육기부에 대한 사회경제적인 가치를 추산해본다. 또한 본 연구에서는 구축한 정량적 분석 프레임을 실제 교육기부 프로그램의 분 석 사례를 통하여 상세히 설명함으로써, 실제 교육기부를 하고 있는 기관이 SROI 분석을 진행할 경우 상황에 따라 어떤 방식으로 활용될 수 있는지를 제시한다. This study is about quantitative analysis for the effectiveness of donation for education which is the most significant issue recently. Most of researches conducted in Korea are focused on the awareness· satisfaction of donation for education using survey or interview, therefore very few studies use quantitative approach. In contrast, the countries that have a long history of donation such as the U.S., the U.K. have conducted researches about quantitative analysis frame for donation of intangible value. Thus, this study adopts the SROI(social return on investment) method used to valuate social enterprise to donation for education so that estimates the socio-economic value of donation for education. In chapter 3, this study explains the SROI analysis framework using an example. This would provide an useful guideline in practice.

Employing the U.S. TAQ data, I analyze the weekday and monthly liquidity patterns of spread and depth. Empirical evidence indicates that weekday spread (depth) pattern follows (Inverted) U-shape, implying that spreads (depths) are greater (smaller) on Monday and Friday during the coarse tick size period. But, such trend vanishes after decimalization. And, I show that January has higher spread and depth than any other month. But I don`t find any strong evidence to support the cause and effect relation between spread and return in January.

This research reports a noticeable premium on the Korea Exchange-listed closed-end funds (CEFs) since 2009. After controlling for the aggregate investor sentiment, investor momentum, and illiquidity measures, the probability of informed trading (PIN) turns out to statistically significantly explain the premium of an average Korean CEF. The PIN may be a proxy for behavioral biases for New York Stock Exchange-listed CEFs which have been persistently discounted to their net asset values (NAVs): The overconfident informed traders can be prone to disposition effect. However, the logical link from asymmetric information and behavioral factors to the documented premium of Korean CEFs is loose. At least a few attributes of Korean CEFs are against the grain: First, the information propagation channel of NAV is unlike that of the U.S. Second, a significant portion of Korean CEFs invest in illiquid real estate properties.

Purpose: This study was designed to investigate fall experiences of the elderly who live alone at their home and to improve the quality of their lives by preventing falls. Methods: The participants in the interview were 9 old people comprised of 1 man and 8 women who were aged over 65. Data were collected through in-depth interviews with the participants and observation of their behaviors. In-depth interview materials were analyzed by the phenomenological method proposed by Giorgi. Results: Fall experience of the elderly living alone consists of absence of a helper, fall due to minor carelessness, poverty, severe pain, negligence of their children, loneliness, cautious behaviour after injuries, desire of death and so on. The whole meaning shows that "they need help desperately." Conclusion: As can be seen from this research, most elderly who live alone are poor, lonely, and disable. As they get injuries from a fall, they suffer from more severe poverty, loneliness, and physical disability. Hence, they might think of death. Therefore, well-being of the elderly should be maintained through the development of fall prevention program to prevent fall.

본 연구는 자사주 취득 공시 전후 내부자거래와 주가반응을 분석하여 추가적인 정보가 시장에 제공가능한지 실증 분석하였으며, 전체시장, 유가증권시장, 코스닥시장의 자사주 취득 공시의 시장반응을 분석하여 시장별 차이가 존재하는지 검증하였다. 2005년부터 2014년까지 내부자거래를 분석한 결과 자사주 취득 공시 전 내부자거래는 회사 주식의 저평가 수준에 따라 영향을 받는 것으로 나타났다. 그리고 자사주 취득 공시의 시장반응은 긍정적으로 나타나 기업의 자사주 취득을 좋은 정보로 인식함을 확인하였다. 시장별 분석에서는 코스닥시장의 경우 매수 표본이 매도 표본보다 유의미한 수익률을 보였으나 유가증권시장의 경우 유의미한 차이를 보이지 않았다. 마지막으로 모든 주식 시장에서 저평가 목적의 자사주 취득 공시기업의 공시 전 내부자 거래행태가 강매도이면 유의미한 장기 수익률을 보이지 않아서 이 경우 시장정보는 허위신호임을 알 수 있다. 이러한 분석 결과는 자사주 취득과 내부자거래의 관계가 새로운 재무 전략 수단으로 활용될 가능성을 시사한다. This study analyzes insider trading and stock price reactions before and after announcements of stock repurchases and empirically analyzes whether additional information could be provided to the market. In addition, the market response to stock repurchase announcements was analyzed to verify whether there was a difference in the entire stock market, KOSPI market, and KOSDAQ market. By examining insider trades in the stock market from 2005 to 2014, we verified that insider trading is affected by the degree to which company’s stock is undervalued. In addition, the market response to the disclosure of stock repurchase was positive, confirming that companies perceived stock repurchase as a good signal. In particular, the market reaction to stock repurchase in the KOSDAQ market is statistically significant, while that in the Kospi market is not. Finally, in all stock markets, if insider trading behavior before the announcements of stock repurchase for undervalued purposes is a strong selling position, there is no significant long-term return, indicating that market information is an incorrect signal. These findings provide evidence that insider trading behavior around stock repurchases can be used as an additional signal.
