Confirmation bias is well known to be the cause of widespread misjudgment in the field of forensic decision-making. In this study, we examined the psychological mechanisms by which confirmation bias affects intentionality judgment in serious injury and death cases that combine the moral characteristics of the perpetrator and victim differently. As a result, participants perceived the case as a more typical criminal case when both the perpetrator and victim were bad people, and gave higher intention to perpetrators' actions in these typical crimes. In particular, it was found that people with a high degree of confirmation bias highly judge the intention of the offenders in a consistent way with the stereotype of criminal cases. However, in serious criminal cases, the moderate effect of confirmation bias has disappeared and only the effect of crime typicality has existed. Finally, we discussed implications of this study and ways to reduce bias in intentionality judgment.

Safety culture degradation signs in nuclear power plants with complex and diverse systems can lead to their equipments performance deterioration. If these signs are neglected, they become potential causes of accidents. Therefore, it is necessary to monitor safety culture in the point of view of organization and management as well as to evaluate safety performance of nuclear power plants. Therefore, This paper suggested a methodology to evaluate safety culture weakness contributing the accidents' root causes in the case accidents occur at nuclear power plants. After reviewing methodologies using at domestic and international industry, the methodology suitable for domestic nuclear power plants was determined.

The aim of this study is to verify the relationships of factors affecting nursing performance of clinical nurses focused on positive affective events. The subjects of this study were 275 clinical nurses from secondary and tertiary general hospitals. Data collection was conducted for two months from May 2021 through an online survey through snowball sampling. Data analyzed was using SPSS 26.0 and AMOS 26.0. The variables affecting job satisfaction included direct effect of positive affective events (β=.65, p<.001), and direct effect of positive affectivity (β=.10, p=.038). Job satisfaction (β=.47, p<.001) had statistically significant direct effects on nursing performance. Positive affective events (β=.32, p=.003) and positive affectivity (β=.05, p=.039) had statistically significant indirect effects on nursing performance. These variables explained for 22% of nursing performance. However, emotional labor had no significant effect on job satisfaction and nursing performance. The results indicate that positive affective events and positive affectivity result in high degree of job satisfaction. Job satisfaction would increase the level of nursing performance. Therefore, in order to improve nursing performance, it is necessary to provide educational opportunities and interventions that can promote positive work environment and positive affectivity.

The problem of social phenomenon is getting more complicated than past decades, and the simulation engineers need more computation power to solve the problem. Therefore, the needs of the computational resources of the modeling and simulation environment are increasing. In the perspective of the simulation, it is necessary to allocate computational resources flexibly so that the simulation can be performed per the available budget range. As an alternative to the simulation environment to accommodate these requirements, cloud service has emerged as an environment in which computing resources can be used flexibly. This paper proposes a web-based simulation framework which consists of a front-end that reconstructs the simulation model using the web, and a back-end that executes the discrete event simulation. This paper also carried out a case study which shows web-based simulation framework has better overall runtime than standalone simulation framework.

The Buma Uprising, which took place in Busan and Masan from 16 to 20 October 1979, was a challenge against the contradictions of the Yushin Regime. Only after 6 days from the insurrection, the 10 26 Accident transpired, in which the then president Park Chung-hee was assassinated, and the Buma Uprising, which acted as the fuse to the shooting, remained as an 'incomplete uprising'. To commensurate with the subject of the paper 'The Truth about Buma Uprising and Historical Reflection', the purpose of this study is to explore how the uprising began, unfolded, and oppressed by comparing it with Busan Uprising and Masan Uprising. It also focuses to discuss, in detail, the effect of the demonstration by college students and the general public and suppression by the forces of the police and military on President Park and his government. This year, we celebrate the 39th anniversary of Buma Uprising, and with all the issues of discovering the truth, restoration of reputation and more, there are decisions and resolves to make including amendment of the legal system. However, there are certain groups of people who act as they led the uprising and mislead and exploit the facts of the events through illegitimate records and testimony, making it impossible to determine the truth. Discovering the truth will require acquisition of objective materials, testimony of those involved in the event and field research as well as imposition of legal and social punishment on those who distorted the truth about the event.

Recently, the antitrust tribunal of Seoul High Court revoked the disposition of Korea Fair Trade Commission(hereafter 'KFTC'). While KFTC determined that the restriction of Korea Pediatrician Association violated article 26 of the Monopoly Regulation and Fair Trade Act(Korean antitrust law), Seoul High court viewed that KFTC failed to prove the compulsory measures and the restraint of competition required in article 26. The 'restriction' of article 26 should be interpreted as 'excessive restriction'. Since entrepeneurs' organization is allowed to limit its member's activities, KFTC could regulate entrepeneurs' organization on a very exceptional basis. In addition, though entrepeneurs' organization did not use compulsory measures to enforce its resolution, its 'excessive restriction' could fit into the notion of 'restriction' of article 26. Under the current medical care system, the price of medical care is decided by Korean government. Therefore the restriction of Korea Pediatrician Association is not likely to have effect on the price. However, the resolution of Korea Pediatrician Association was aimed to decrease the supply of medical care. Therefore the resolution is capable of having effect on the competition. In this sense, though KFTC failed to submit direct evidence to support the decrease of quantity, there could be possibility of restraint of competition. The Seoul High Court's decision has important implications. The leading case on restraint of competition(Supreme Court 2002Du8628, Posco case) was delivered in 2007. However the remaining issue such as the standard and scope of restraint of competition is not clear. Through reappeal case of this decision, Supreme Court has to decide the line between competition and its restraint.

An OPEC production announcement is a major source of supply disruption that has a significant impact on the international crude oil market. In this study, the effects of OPEC's announcements are analyzed using event study methodology. Considering the oil price volatility and structural changes in the oil price, we divide the entire period into three periods and analyze the impact of OPEC's production quota announcements, including 'cut', 'hike', and 'maintain'. As a result of the analysis, we observe that the degree and direction of abnormal returns differ according to the announcements in each period. In addition, by subdividing oil price surge and plunge period into two sections, we analyze the effect of OPEC's 'maintain' announcements. During the oil price plunge period, the amount of abnormal returns was significant. This study provides policy implications for oil trading strategies and for the impact of OPEC announcements during periods of oil price fluctuation.
