This study focuses on predicting which firms will increase capital by issuing new stocks in the near future. Many stakeholders, including banks, credit rating agencies and investors, performs a variety of analyses for firms' growth, profitability, stability, activity, productivity, etc., and regularly report the firms' financial analysis indices. In the paper, we develop predictive models for rights issues using these financial analysis indices and data mining techniques. This study approaches to building the predictive models from the perspective of two different analyses. The first is the analysis period. We divide the analysis period into before and after the IMF financial crisis, and examine whether there is the difference between the two periods. The second is the prediction time. In order to predict when firms increase capital by issuing new stocks, the prediction time is categorized as one year, two years and three years later. Therefore Total six prediction models are developed and analyzed. In this paper, we employ the decision tree technique to build the prediction models for rights issues. The decision tree is the most widely used prediction method which builds decision trees to label or categorize cases into a set of known classes. In contrast to neural networks, logistic regression and SVM, decision tree techniques are well suited for high-dimensional applications and have strong explanation capabilities. There are well-known decision tree induction algorithms such as CHAID, CART, QUEST, C5.0, etc. Among them, we use C5.0 algorithm which is the most recently developed algorithm and yields performance better than other algorithms. We obtained data for the rights issue and financial analysis from TS2000 of Korea Listed Companies Association. A record of financial analysis data is consisted of 89 variables which include 9 growth indices, 30 profitability indices, 23 stability indices, 6 activity indices and 8 productivity indices. For the model building and test, we used 10,925 financial analysis data of total 658 listed firms. PASW Modeler 13 was used to build C5.0 decision trees for the six prediction models. Total 84 variables among financial analysis data are selected as the input variables of each model, and the rights issue status (issued or not issued) is defined as the output variable. To develop prediction models using C5.0 node (Node Options: Output type = Rule set, Use boosting = false, Cross-validate = false, Mode = Simple, Favor = Generality), we used 60% of data for model building and 40% of data for model test. The results of experimental analysis show that the prediction accuracies of data after the IMF financial crisis (59.04% to 60.43%) are about 10 percent higher than ones before IMF financial crisis (68.78% to 71.41%). These results indicate that since the IMF financial crisis, the reliability of financial analysis indices has increased and the firm intention of rights issue has been more obvious. The experiment results also show that the stability-related indices have a major impact on conducting rights issue in the case of short-term prediction. On the other hand, the long-term prediction of conducting rights issue is affected by financial analysis indices on profitability, stability, activity and productivity. All the prediction models include the industry code as one of significant variables. This means that companies in different types of industries show their different types of patterns for rights issue. We conclude that it is desirable for stakeholders to take into account stability-related indices and more various financial analysis indices for short-term prediction and long-term prediction, respectively. The current study has several limitations. First, we need to compare the differences in accuracy by using different data mining techniques such as neural networks, logistic regression and SVM. Second, we are required to develop and to evaluate new prediction models including variables which research in the theory of capital structure has mentioned about the relevance to rights issue.

The purpose of this study was to investigate a moderating effect of social work practitioners' support between psychological crisis and social participation of divorced retired men. For this, psychological crisis, social participation, and social work practitioners' support were completed by 248 divorced retired men registered during the last five years in Hope Job Center for the middle aged group in Seoul and Gyeonggi Province. Correlation analysis was performed to determine the general trend of the measured variables based on the collected data, simple regression analysis was conducted to determine the relationship between variables, and hierarchical regression analysis was performed to examine the moderating effect. The results of this study are as follows. First, psychological crisis was found to have a negative correlation with social participation and social work practitioners' support. Second, social worker practitioners' support between psychological crisis and social participation showed a significant moderating effect. Based on these findings, this study is significant in terms of providing needs for interventions of social support through methods such as programs for psychological support and education about social participation for divorced retired men.

Recently Korea has stepped into a stage of sluggish development, and the unemployment of young people has become a major issue. Especially in 1998 IMF economic shock was influential in formulating government policy and social economic structure on employment. Restructuring now becomes everyday words and further restructuring is already under way. Owing to the growing economic crisis and resultant unemployment and initial appointment shall be considered conditional. Young job seekers are grappling with mastering their native language and unnecessary experiences. These unnecessary experiences are needless waste of time and money. Educational system in university may be affected by environmental changes in population of students and business crisis. Sometimes the departments made a very low rate of employment may be abolished or merged in university. The government will demand us in the work of reform by doing NCS. The government is now ask to teach, train and employ students on the basis of NCS especially in high-school, job training center, and college and university. NCS has advantages and disadvantages. NCS may reduce waste of time and money to make unnecessary experiences, provide standard course to prepare educational system. It will be a big help to adapt properly and make better employment system. The most negative element of the program is application to humanities and social sciences by the same standard with technology and engineering department in the university. Standardization of each educational course will not react quickly to rapidly changing situations in the future.

This article discusses David Henry Hwang's M. Butterfly as a suggestive text for examining Western masculinity in crisis in the post-imperialist age, in which territorial imperialism is no longer valid. Previous scholarship on M. Butterfly has centered around the interlocking dynamics of imperialism, racism and sexism. Such critical attentions focus on how Hwang deconstructs racialized significations of the East and the West. In these discussions, the issue of gender is often addressed merely as a trope to represent the power relations between the East and the West. As such, gender as well as sexuality is highlighted as the very source of subversion of the power relations. My discussion departs from a critique of the gendered trope of the East and the West, highlighting a postmodern agent, the allegedly feminized character Song Lining: a Chinese actor who passes for a woman for political purposes in postcolonial China. Remaining an "inappropriate/d other" in the gendered imperialist discourse, Song becomes an emergent subject, who is capable of playing gender ambiguity for reclaiming a devalued identity, that of homosexual Asian man. Discussing how the central character Rene Gallimard's masculine identity is constructed in a cross-cultural space and how it evolves, I also argue that Gallimard's melancholic death signifies a historical unsustainability of imperialist masculinity in the postmodern/postcolonial age since World War II.

It has been more than four years since the outbreak of global financial crisis. However, the world economy continues to be challenged with new crisis such as the European debt crisis and the fiscal cliff issue of the U.S. The global economic environment remains fragile and prone to further disappointment, although the balance of risks is now less skewed to the downside than it has been in recent years. It's no wonder that maritime business will be bearish since the global business affects the maritime business directly as well as indirectly. This paper, hence, aims to predict the Baltic Dry Index representing the shipping business using the ARIMA-type models and Hodrick-Prescott filtering technique. The monthly data cover the period January 2000 through January 2013. The out-of-sample forecasting performance is measured by three summary statistics: root mean squared percent error, mean absolute percent error and mean percent error. These forecasting performances are also compared with those of the random walk model. This study shows that the ARIMA models including Intervention-ARIMA have lower rmse than random walk model. This means that it's appropriate to forecast BDI using the ARIMA models. This paper predicts that the shipping market will be more bearish in 2013 than the year 2012. These pessimistic ex-ante forecasts are supported by the Hodrick-Prescott filtering technique.

The purpose of the present study was to examine psychological consequences of indirect trauma exposure through the disaster news. Participants(N=439) completed some self-report questionnaires such as Posttraumatic Risk Checklist(PRC), Impact of Event Scale-Revised(IES-R), and Multidimensional Fear of Death Scale(MFODS) at 68.11(±18.47) days after the Sewol ferry disaster. The data were analyzed with structural equation modeling by AMOS 23.0 program. The results showed that fear of death and periand post-traumatic crisis factors mediated the association of news exposure immediately after disaster and posttraumatic stress symptoms. Findings in this study indicated that news exposure immediately after disaster influenced fear of death which led to the peri- and post-traumatic crisis, and these crisis factors increased posttraumatic stress symptoms. Finally, limitations of this study and suggestions for future study were discussed.

This study examines the issue of space management of university facilities by an assessment model as part of efforts to deal with the crisis of universities. To this end, the study addressed efficiency issue and structural problems using assessment model factors, with the aim of figuring out legitimacy and allocating methods for this purpose. Selected model factors included utilization ratio, residual ratio, vacancy ratio, and occupancy ratio, while for the latter, we investigated into the present situations of space use, focusing on construction, design, and living dimensions. As a result, the study suggested that in the future universities will resort to extension and rebuilding or new building for their facilities. To ensure space efficiency without conflict, we should follow legitimacy of space allocation and composition, building quality university facilities, creating quality environment, preventing tuition from rising or Improving welfare to keep pace with the new era.

The socioeconomic inequalities in health have recently become an important public health concern in South Korea, and the issue has gained increasing attention from many South Korean researchers due to the increasing income inequality and Widening social polarization following its economic crisis in the late 1990s. However, despite the mounting literature on health inequalities published in recent years, the history of research on health inequality in South Korea is premature in comparison to the long histories in several Western countries. Understanding the historical background underlying the issue of health inequality research may aid in establishing and accumulating scientifically solid evidence in South Korea. It may also direct the South Korean research community to develop research agendas that are. more politically and academically appropriate for South Korean society. This paper describes the historical development of health inequality research in the West and introduces several important issues contributing to the advancement of health inequality research. Specifically, the major studies conducted before and after the UK Black Report are presented. In addition, the history and current status of health inequality research in South Korea are documented and evaluated. Finally, several research agendas for the quantitative and qualitative improvement of health inequality research in South Korea are proposed.

The political dynamics of Malaysia in 2016 should be seen as a process of losing an political opportunity mainly due to the split in opposition parties. The opportunity for political development was triggered by the ruling party in crisis. The ongoing 1Malaysia Development Berhad (1MDB) scandal involving the Prime Minister Najib Razak would have provided a favorable condition for the transfer of power. The opposition parties have however failed to utilize the chance that has arisen since the general elections in 2008 and 2013 due to the chronic problem of disunity. It can be seen as distortions of political development referring to a phenomenon in which a chance for regime change formed by the crisis in authoritarian regime is distorted by internal conflicts among opposition parties. Malaysia's political turmoil seemed to paralyze its economy while foreign policy was used as a tool for domestic politics. It was reported that the key economic indicator have worsen including exports and budget deficit. The ringgit had dropped to its lowest level since the economic crisis in 1997-98 which was mainly attributed to diminishing credibility on the Najib's administration. Najib's political struggle has also impeded Malaysia's foreign policy which has attempt to embrace China and the Rohingya issue. The chance to manage key risks would be diminished if oppositions' disunity continues as there is speculation that the general election could be held in 2017.
