In previous studies, stress in the Information and Communication Technology (ICT) work environment was focused on lowering work performance by negatively affecting the emotions of organizational members. In the current corona pandemic era, as the ratio of organizational members working from home in a smart environment increases, the need for research on the effects of positive and negative stress on work performance is being raised. Accordingly, by applying the Affective Event Theory to the emotional effects of stress on employees' emotional responses, the effects on work performance were analyzed by dividing them into positive and negative emotions. Also, the effect of smart work on work performance was analyzed. This survey was commissioned by a research company and analyzed using Smart PLS 3.0 tool. Therefore, based on the research results, it was suggested that stress does not only negatively affect the emotions of employees, but that the challenge stress that appears in the mind to achieve a goal induces positive emotions in the employees' emotions and helps to improve work performance.

This study was conducted to understand the emotional and situational context where non-suicidal self-injury occurs in everyday life. Sixty adults(age 19-35) completed daily surveys assessing positive and negative emotions, stressful events, self-injury thoughts, and behaviors for two weeks. Using a total of 663 collected entries, we analyzed specific personal emotions and stressful events related to non-suicidal self-injurious thoughts and behaviors. As a result, high negative emotions, low positive emotions, and total stress event scores were significantly related to self-injury thoughts and behaviors. In the model in which both emotion and stress were inserted as predictors, the low level of positive emotion showed a significant related to non-suicidal self-injurious behavior. These results suggest that negative emotion management and overall positive emotion reinforcement are important in emotion regulation intervention for non-suicidal self-injurious patients. The meaning of this study is that it searched for risk factors of non-suicidal injury in everyday life using a short-term longitudinal method.

The purpose of this study is to analyze the effects of the collective characteristics of SMEs on M&A activity on the disclosure effect of mergers and long-term business performance after mergers. From 2000 to 2012, we examine 717 cases of small and medium-sized enterprises (SMEs) using multiple regression analysis and difference analysis. The results of this study are as follows. First, it is confirmed that the effect on the merger announcement effect is the same as the previous study on the Korean capital market listed companies except for the effect of diversification, listing effect, and cross-border effect. In addition, we have found that firms with higher performance in the past have higher excess returns in the disclosure effect of mergers and acquisitions. Second, unlike the previous studies that non-related mergers have a positive effect on long-term operating performance, for the characteristics of SMEs with lower market competitiveness than that of average listed companies, SMEs merging with same industry group companies have a positive effect on long-term operating performance. This study provides a new perspective on the merger and acquisition of SMEs by examining the effects of M&A announcement and long-term performance.

We test the hypothesis whether foreign direct investments(hereafter "FDI") can affect the changes of the firm value. In this study, we use a newly developed event study technique, referred to as value-based event study approach(hereafter "VESA"), which is based on the seminal papers of M&M(1958, 1961, 1963) and Lee(2006, 2007). The empirical findings about the effects of FDI's on the intrinsic firm values, which can be measured by intrinsic Q(hereafter "IQ") values of the VESA, are as follows; First, the FDI's are carried out by healthy firms in terms of high IQ's. The IQ values become higher during the post-FDI period than prior to performing FDI's. Second, among the four components of IQ values, the value of assets-in-place, the value of intangible assets, and the value of growth opportunities are all increased during the post-FDI period, except the value of current earnings. Third, the same results are observed in all the samples classified by industry. In sum, thanks to the above findings in this study, we can conclude that the announcements of the FDI's are good and reliable indicators for the firm to signal to the market that the FDI firms are healthy in intrinsic firm values, and also that they have good chances to increase their firm values through the new investments abroad.

Police officers in charge of investigating sexual assault cases are likely to have suspicions in the process of investigation to find out the truth about the case, which leads to secondary victimization to the victims, and these concerns are often unveiled as social problems. This study suggested the research question that what the causes of secondary victimization derived from the police officers in charge of sexual assault investigation are. The purpose of this study was to contribute to the restoration of the trust of the police by preventing or minimizing the secondary victimization of sexual assault cases in the investigation process. Among the personal characteristics of police officers, rape myth, tolerance n violence and hostile gender discrimination influenced suspicion and prejudice, and rape myth and hostile gender discrimination affected the lack of sensitivity. Among the workplace-related characteristics, the duration of employment and experience in sexual assault cases affects the lack of sensitivity. In addition to the revision of the law and the improvement of the system of sexual assault, the prejudice against the sexual assault inherent in the attitudes and behaviors of the police officers in charge of the sexual assault cases should be improved.

In this paper, we investigate intellectual reaction differences among market participants to various corporate information announcements and the main information prompting investors to trade. Our research is based on IPO companies listed on the KOSDAQ exchange from January 2000 to September 2012 and concentrates on three information disclosures - bonus issue, seasoned equity offer, and new investment in facilities announcements. We find that intellectual market participants react positively to bonus issues and seasoned equity offers, but negatively to new investment announcements. Market trading volume increases before the positive events and all cgroups actively buy shares during these periods. For the negative events, only institution participants show active selling. Overall, institutions act as momentum traders, and individuals and foreigners as contrarian traders. We also discuss the implications of this study.
