Background: Industrial accidents can determine the overall level and quality of the work environment in industries and companies that contribute to national economic development. Korea has transformed the country from an international aid recipient to a donor country, but it has ranked first among the Organisation for Economic Co-operation and Development member countries in the number of fatal industrial accidents. Little has been known about the policy effects in terms of the workers' insurance for their industrial accidents and rehabilitation. This study raises two research questions about the influence of workers' personal characteristics and vocational rehabilitation services on their return to workplaces. Methods: The study implements weighted logistic regression analysis using propensity score matching. This research utilizes the relevant dataset (3,924 persons) of Korea's industrial accident and insurance. Results: The findings show that the level of workers' awareness of health recovery and their counseling for rehabilitation by physicians had positive effects on their return to work. Environmental factors such as workers' job stability at the time of industrial accidents and the temporal effects of industrial accidents (e.g., the level of disability, their age) had negative impacts on their return to work. Conclusions: These findings have policy implications that the concentration of rehabilitation services for patients who have been mildly affected by industrial accidents would be effective in the short and medium term. The findings also highlight the necessity of ongoing policies about workers' vocational recovery with concrete evidence about policy impacts.

본 논문은 정부 R&D 지원 중소기업의 사회 환원 실행에 영향을 미칠 수 있는 잠재적 다차원 결정요인을 규명하고자 하였다. 이를 위해 중소기업 310개 사업체를 대상으로 사회 환원에 관한 설문조사를 실시하고, 구조방정식모형을 적용하여 이와 관련한 주요 요인 간의 관계를 검토하였다. 주요 결과에 따르면 정부 R&D 지원 중소기업의 사회 환원에 대한 대중적 인식 수준이나 중소기업의 의지는 어느 정도 갖추어졌지만 사회 환원의 실행을 위한 중소기업 내부의 문화나 시스템은 상대적으로 미흡한 상황임을 보여주고 있으며, 이는 중소기업의 사회 환원 내부시스템 구축에 정책적 조준이 우선되어야 함을 의미한다. 또한, 정부의 사회 환원 정책은 중소기업의 사회 환원 의사에 영향을 미칠 수 있도록 정책 전달 장치를 보완하여야 하고, 중소기업의 사회 환원 활성화를 위해서는 중소기업의 성장이 선행되어야 한다는 점에 주목해야 함을 시사한다.

The behavioral finance view on the existence of asset pricing anomalies is based on two factors: investors' sentiment and limits to arbitrage. This paper tries to examine the effect of investors' sentiment on the stock price in the Korean stock market. In order to measure investors' sentiment, we constructed the sentiment index using principal component of five sentiment variables. By using sentiment index as an additional independent variable to three risk factors, impacts of the sentiment index on individual stocks and 25 portfolios sorted by BM-size are examined. Main results found are as follows: 1) not only all three risk factors show positive impacts on the return of individual stock, but also the sentiment index has a positive impact. SI alone explains 15% of individual return variation. 2) among four independent variables, the most important factor turned out to be the market risk factor and investors' sentiment has better explanatory power on stock price than the size effect. 3) after controlling the market risk factor, the coefficient of the sentiment index for the smallest size and highest book/market value portfolios is significantly positive. 4) all the coefficients of the sentiment index for 25 portfolios sorted by BM-size have significant positive value after controlling size or (and) value.

On-line clothes sale are on the increase, and the returns(for replacements or refunds) of the clothes are also increasing. Many studies on off-line consumers' complaints were made before, but few studies on the returns of clothes sold on-line have been made. From this viewpoint, this study was conducted to know what effect returns of clothes sold on-line have on their brands. Therefore, this study was first focused on the factors affecting complaint acts(return intention or return acts) such as lack of information and recognition of product, delivery errors and product defects concerning on-line sales, and second investigated the changes of buyers' attitude toward the brand following the their acts of returning the buyers, and third looked into the changes of on-line buyers' attitude toward the brand. The study is carried out by subdividing the objects of the study into return action(replacement, refundment) and purchasers who experienced return intention. Such experience is demonstratively analyzed to find how it has affected the attitude toward the brand. The study comes up with the following outcomes. First, the effect factor causing complaint action(return action, return intention) on-line is shown as the lack of the information and recognition of the product. Second, it is revealed that the effect factor causing complaint(return action, return intention) does not lie in an error in delivery or a defect of a product. Third, the positive response of a brand to a return action does not raise the repurchasing intention and positive attitude of purchasers who experienced returning a product, but lowers their private complaint action intention. Fourth, the repurchase intention of purchasers who experienced return intention for the brand is lowered, but their negative attitude and private complaint action intention is not raised.

This studies were carried out to get characteristics of frequency distribution, probable flood flows according to the return periods, and the correlation between return periods and those length of records affect the Risk of failure in the annual maximum series of the main river systems in Korea. Especially, Risk analysis according to the levels were emphasized in relation to the design frequency factors for the different watersheds. Twelve watersheds along Han, Geum, Nak Dong, Yeong San and Seom Jin river basin were selected as studying basins. The results were analyzed and summarized as follows. 1. Type 1 extremal distribution was newly confirmed as a good fitted distribution at selected watersheds along Geum and Yeong San river basin. Three parameter lognormal Seom Jin river basin. Consequently, characteristics of frequency distribution for the extreme value series could be changed in connection with the watershed location even the same river system judging from the results so far obtained by author. 2. Evaluation of parameters for Type 1 extremal and three parameter lognormal distribution based on the method of moment by using an electronic computer. 3. Formulas for the probable flood flows were derived for the three parameter lognormal and Type 1 extremal distribution. 4. Equations for the risk to failure could be simplified as $\frac{n}{N+n}$ and $\frac{n}{T}$ under the condition of non-parametric method and the longer return period than the life of project, respectively. 5. Formulas for the return periods in relation to frequency factors were derived by the least square method for the three parameter lognormal and Type 1 extremal distribution. 6. The more the length of records, the lesser the risk of failure, and it was appeared that the risk of failure was increasing in propotion to the length of return periods even same length of records. 7. Empirical formulas for design frequency factors were derived from under the condition of the return periods identify with the life of Hydraulic structure in relation to the risk level. 8. Design frequency factor was appeared to be increased in propotion to the return periods while it is in inverse proportion to the levels of the risk of failure. 9. Derivation of design flood including the risk of failure could be accomplished by using of emprical formulas for the design frequency factor for each watershed.

The production of Korean offshore fisheries has been gradually decreasing due to the severe depletion of offshore fisheries resources caused by excessive fishing efforts. The production of the offshore fisheries in 2016 was the lowest since 1975. So the federal and local governments in Korea adopted and implemented various fisheries management plans and policies in order to restore fisheries resources. However, these plans and polices have not been successful in re-establishing fisheries resources. Thus, in order to accurately diagnose the situation with regard to offshore fisheries, this study sought to estimate not only the return to scale by fishing gear of offshore fisheries, but marginal productivity of individual fishing gear based on production factors derived from offshore fisheries production functions. The study was organized in the following manner. First of all, this study estimates production functions of offshore fisheries. The Cobb-Douglas and the translog production functions are adopted as offshore fisheries production functions. Specifically, the functions are estimated by crew, vessels, and offshore resource as production factors. The offshore resource is estimated by the Clarke Yoshimoto Pooley model based on the surplus production model. Secondly, the fisheries production functions are extended to the fixed-effect model and the random-effect model with panel data. Thirdly, this study analyzes the return to scale of offshore fisheries and the marginal productivity of the production factors from the estimated offshore fisheries production function. In conclusion, this study suggests plans and countermeasures for productivity improvement by group (labor intensive or technology intensive) based on the characteristics of individual offshore fishing gear.

본 연구에서는 최근 기관투자가의 투자대상으로서 그 중요성이 커지고 있는 국내 오피스에 대해서 해외 선행연구에서 유의하게 입증된 여러 스타일인자의 유의성을 검정하였다. 검정대상이 된 설명변수에는 지역, 규모(평가금액), 가치성장성(소득자본수익격차), 임대차조건(임차인수, 평균임대차기간, 핵심임차인비중) 등이 포함되었다. 분석자료는 감정평가에 기반한 국토교통부 임대사례조사 DB 중 일부를 이용하였다. 분석결과 다음과 같은 시사점을 얻을 수 있었다. 우리나라 오피스시장의 경우 스타일인자로서 지역은 여전히 중요한 의미를 가지며, 이와 함께 규모도 유의하게 작용하였다. 단 핵심지역의 대형자산일수록 위험과 수익이 높게 나타나 일반적인 믿음과 차이가 있었는데, 이는 분석기간 동안 서울 3대권역의 대형오피스 가격이 급등했기 때문인 것으로 생각된다. 이러한 현상은 미국의 선행연구에서도 발견되고 있어 지역과 규모의 역할에 대해 신중한 접근이 필요함을 알 수 있었다. 가치성장성의 경우 가치성이 클수록 예상한대로 위험과 수익을 낮추는 것으로 나타나 국내에서도 유의한 스타일인자임이 확인되었다. 임대차조건과 관련해서는 임차인수 만이 유의하게 나타났는데, 이 역시 예상대로 임차인 분산이 잘 이루어질수록 위험과 수익이 낮은 것을 알 수 있었다.

The purpose of this study is to deduce dwelling selection criterion and to consider change of values and consciousness of dwelling on people who return to farming & going to village. For that, questionnaire of evaluation of housing choice is conducted by people who return to farming & going to village in Jellanam-do by the AHP. The results are as follows. First, four factors as the primary hierarchy structure and 12 factors as the secondary hierarchy structure of dwelling selection criterion are deduced. The primary hierarchy are "education environment", "economic & Convenience in life", "residence safety and image", and "economic value". Second, weight value deduced from the primary hierarchy structure is showed that "economic & convenience in life(0.345)" is the highest and next is "education environment(0.262)". "Residence safety and image(0.237)", and e "economic value(0.157)" is relatively low(C.I. 0.213). Third, for the secondary hierarchy structure, the case of life convenience is showed that economic condition(0.403) is the highest, the case of educational condition is showed that education facilities(0.479), the case of residence safety and image is showed that residence area(0.490) is the highest, and the case of economic importance is showed that financial technology(0.470) is the highest.

Recently hospitals are trying to meet requests of patients by reflecting regular survey results of patients into hospital's management in order to increase patients' satisfaction and the rate of return visit. In this paper, degree of patients' satisfaction and the rate of return visit were analyzed using surveys of hospital selection factors and the characteristics of aesthetic plastic surgery. This analysis results can be used as data for setting up efficient management direction of aesthetic plastic surgery hospitals. In the main results, facilities and medical trust factor was the primary cause for aesthetic plastic surgery patients to select hospitals and the results showed that hospitals have to consider carefully not only aesthetic plastic surgery patients but also guardians such as parents or friends because patients are acquiring surgery information from them. The results also showed approachableness to hospitals was not important factor to select a hospital.

This study analyzes the critical factors that decide the job continuity of married women after one of their life events, childbirth. It is based on the employment data from KLIPS(Korea Labor and Income Panel Study). Vols. 1-4, having observed 128 young mothers who gave birth to children after 1997. The analysis showed that women's employment after their maternity leave depend on whether new mother return to their previous job or not. The Following results are obtained: First, women's age, education, availability of caretakers for their children, and family income have a positive effect on the women's return to their pre-leave employers after childbirth. Second, professional or office work and the frequency of job transition before childbirth have a positive effect on women's employment in new jobs after childbirth. Third, women's age, availability of caretakers of their children, and professional or office work are critical factors that have a positive effect on women's job continuity after childbirth, whereas the frequency of job transitions has a negative effect on employment for women.
