The purpose of this study is to empirically analyze the effect of information related to the largest shareholder's change on the likelihood of reporting a loss for firms listed on the Korea Exchange. Specifically, this study conducts a logit regression analysis to examine the firm's loss reporting with frequent changes in the largest shareholder among the largest shareholder change types. So, it controls the impact of a firm's loss reporting, such as the previous year's loss reporting and discretionary accruals. As a result of the analysis, firms whose largest shareholder have changed more than 2 times in the accounting period are found to have higher firm risk in loss reporting than other firms. The results of this analysis confirm that frequent changes in the largest shareholder, which are disclosures of investment risks on the Korea Exchange, may result in investment risk situations such as loss reporting.

The primary purposes of this study are to find a proper model for government's selections of Mainbiz and present what are the better weights of the current indexes. We prepared three sets of models：first one using original 10 variables; second one using 9principally composed variables; third one using 7 principally composed variables. Among 3 models, the last one had higher explanation power than the other two models. Therefore, if index weights are adjusted according to the third newly developed model, the credibility in evaluating and selecting Mainbiz will be improved. When transforming the index weights and running the analysis, 5 variables(organization process, marketing management, management process, production-facility states, the level of forecasting) have more direct influences than other 4 variables(innovation strategies, knowledge management, achieving level, operational level) on selecting Main-biz.

Although the term 'family business' is relatively new, this style of business is universal. An Unusual feature that must be noted, is that even though it is a common style of business is not clearly defined. The purpose of this study is to identify the different family participation patterns, and the variables that effect different types of participation. '1997 Daewoo Panel Data' was used. Some descriptive statistics and a multinomial logit model were employed for the analysis. The standard type of business focused on in this study was a family owned and operated 'ma and pa' typed business and the sample was limited to households where one or both of the partners involved in a family owned and operated business. The main resets obtained from this sample were as follows: 1. Personal characteristics such as respondents' gender, age and educational level were important variables that effected the participation of family members in the business. As can be seen in the gender analysis, family businesses owned by men showed all available patterns of family operated businesses in relatively high numbers. A large percentage of businesses owned women were of self-employed pattern. According to the analysis by age and educational level, young people with a high level of education tend to managed their small businesses by employing others rather than utilising the self-employed or family operated pattern. 2. While big families showed a high percentage of a combination pattern of a family-run, and ordinary employer/employee company, relatively small families usually opted for purely family-run businesses. Whether the family have children under 6 or not, and the number of children under 6 did net significantly effect to the patterns of the family system of small family businesses. 3. The size, location and kind of family business also effected participation patterns of the family members significantly. These results suggest that further study will be required to gain more exact and meaningful information to help Korean family businesses.

Some OECD countries are showing signs of decoupling in the transportation sector. In terms of sustainable development, the decoupling of economic activities and greenhouse gas emissions in the transportation sector is very important. This study calculated a decoupling index of greenhouse gas emissions in the transportation sector for 25 OECD countries. Also this study analyzed the impact of energy transition on decoupling regimes. According to the analysis, a considerable number of countries have reached the decoupling phase, and some countries have shown strong decoupling regime in which greenhouse gas emissions are reduced despite economic growth. From ordered panel logit analysis, energy transition had significant impact on achieving decoupling phase. Electrification of transport had a positive effect on the decoupling, while the gasification was not significant. In addition, small traffic, high urbanization rates, strong environmental policies, and high trade opening have had significant effects on achieving decoupling.

This study investigates the spatial distribution characteristics of Korean fashion industries during the last decade, in which the economic geography of fashion industries has changed dynamically with economic globalization and "thus resulted in increased" demand "of" diversification. In particular, this study examines the spatial distribution patterns of fashion industries in the Seoul metropolitan area where fashion industries are highly agglomerated. For the purpose, this study applies Moran's I Index of spatial autocorrelation analysis for seven functional sectors of fashion industries related to fashion production. The global and local agglomeration patterns are examined for each functional sector. The results clarify the distinction in the spatial agglomeration patterns among the seven functional sectors of fashion industries in the Seoul Metropolitan area. Logit models are developed to examine the interrelationships among functional sectors in their spatial agglomeration distribution patterns. By conducting binary logistic regression analysis, we find out how the spatial agglomeration of each functional sector is related to the others.

Purpose: The purpose of this study was to examine the functional category, the item structure and the model-data fit of the neck disability index (NDI) of neck pain subjects by performing a Rasch rating scale analysis. Methods: The data was obtained from the assessments of 71 college students (males: 27, females: 44) with neck pain. The data of the NDI was applied to the Rasch's rating scale model to estimate the difficulty of items, the goodness-of-fit of each item, the separation reliability and index, and the rating scale. Results: The 'sleep' item showed misfit and nine items were founds to be fits for self-reporting of disability due to neck pain. The most difficult item of the remaining 9 items was 'work' and the easiest item was 'headache'. The transformation formula score=(logit score+7.10)/(7.10+0.11)$\times$100. The 6 response levels of the NDI were validated according to the structure of the rating scale. The item and subject reliability of the separation reliability was 0.97 and 0.85, respectively. Conclusion: We proved that the NDI for self-reporting of disability of daily activities due to mild neck pain was valid and reliable. This study suggests that individuals with mild neck pain may be assessed by using the modified NDI that does not include the 'sleep' item in the 10 items of NDI.

Background: Since 2003, Korea has consistently shown the highest suicide rate among the Organization for Economic Cooperation and Development countries, and suicide remains the major cause of death. In particular, men are 2-3 times more likely to commit suicide than women, which called the 'gender paradox of suicide.' The areas with frequent suicide have spatially clustered patterns because suicide with a social contagion spreads around the neighborhood. The purpose of this study was twofold. The first was to estimate the hotspot areas of age-standardized male suicide mortality from 2008 to 2015. The second was to analyze the relationship between the hotspot areas and the regional characteristics for study years. Methods: The data was collected through the Korean Statistical Information Service. The study areas were 227 si gun gu administrative districts in Korea. The hotspot area was used as a dependent variable. Socio-demographic variables (number of marriages per 1,000 population, number of divorces per 1,000 population, and urbanization rate), financial variables (financial independence and social security budget), and health behaviors (EuroQol-5 dimension [EQ-5D], and depression experience rate) were used as independents variables. Results: The hotspot areas were commonly located in Gangwon-do, Chungcheongnam-do, Gyeongsangbuk-do, and Chungceongbuk-do. According to the results of panel logit regression, the number of divorces per 1,000 population, social security budget, and EQ-5D were statistically significant variables. Conclusion: The results of hotspot analysis showed the need for establishing a prevention zone of suicide using hotspot areas. Also, medical resources could be considered to be preferentially placed in the prevention zone of suicide. This study could be used as basic data for health policymakers to establish a suicide-related policy.

Prior studies concerning the analysis of parents' homeownership on its offspring usually focus on the transmission of tenure between two generations. This study adopted a more comprehensive approach on this topic so the effects of parents' homeownership were analyzed through the economic performance of their sons. Korean labor panel data were used to test hypotheses on intergenerational transmission of parents' homeownership. The period covered years 2000 to 2014, consisting of about 862 samples, while many socioeconomic variables were selected through a filtering process. The results of the three hypotheses showed the following consequences. First, parents' homeownership was a meaningful factor in determining their son's housing tenure. Second, parents who are homeowners tended to have more educated sons. Third, parents' homeownership did not affect their son's annual income. This study showed more extensive effects of homeownership, and government strategy must consider this additional benefit in homeownership policies.

The conversion of the internal combustion engine vehicle to the electric vehicle is suggested as a solution to the problem of global climate change and environmental pollution. Accordingly, this study was started to promote the use of electric vehicles. The purpose of this study is to identify the basic background knowledge and current status of electric vehicles in Korea and abroad, and expand from previous understanding on which factors affect ones choice on electric vehicles by considering individual characteristics and context in detail. In the analysis, a set of demand forecasting models were constructed by grouping the respondents based on the household characteristics as well as the vehicle ownership. At the time in need for better understanding of the feasibility of electric vehicles, it is expected that the research can assist the promotion of electric vehicles. In the follow-up study, I would like to continue the research on the activation of electric vehicles.

Purpose: As an interest in the elderly medical expenses increases, elderly people are increasingly purchasing indemnity private health insurance. Authors tried to investigate factors of having the indemnity private health insurance among the elderly people aged 65-75 years. Methods: We conducted panel logit regression analysis on 2,465 subjects as of 2016 using Korean Health Panel from 2010 to 2016. The dependent variable was whether to enroll in the indemnity private health insurance. The explanatory variables included socio-demographic characteristics, economic factors, health status, and health behaviors. Findings: As a result of the analysis of factors of purchasing indemnity private health insurances, it was analyzed that people with larger family, educated, pensioner, high household income or no disability were more likely to have indemnity private health insurance. Practical Implications: Considering the results of this study, the factor of purchasing indemnity private health insurance among elderly people were more likely to be their economic than demographic characteristics such as sex, age, and marital status. Policy makers should make efforts to reduce the burden on the elderly medical expense and to improve equity of medical use through institutional improvement such as raising age limit and lowering premium of indemnity private health insurance and expansion of public health insurance.
