Purpose: This study aimed to examine the process from occurrence of a hospital nurse's suicide to workers' compensation approval, responses of the parties involved, issues debated during approval deliberations, and significant policy changes resulting from the incident. Methods: We conducted in-depth interviews with involved parties and collected various documents, including newspaper articles, forum proceedings, and the agency report on determination of workers' compensation. Content analysis was performed on the collected data. Results: A Joint Task Force continuously reported its progress and findings through mass media such as newspaper, radio, and TV. These activities exerted pressure on a government agency to conduct an occupational disease review and significantly impacted the workers' compensation approval. The agency recognized associations between the hospital's inadequate nurse training and the suicide but did not confirm the excessive overtime and workplace harassment experienced by the nurse as causes of the suicide. This case's media coverage and impact resulted in a law prohibiting workplace harassment and a hospital system dedicating at least one nurse to training activities. Conclusions: This incident had a significant social impact as the first case of workers' compensation approval for a hospital nurse's suicide. However, the case produced no structural changes in nurses' working conditions such as heavy workloads.

PURPOSE: Focusing on the factors that influence the infectious disease emergency response policy (approached by dividing the factors into health policy management and economic policies), both SARS and MERS cases were based on the legal system, manpower, and budget, but there has not been enough learning from the epidemic. This study focused on infectious disease emergency governance, which various studies have neglected despite its social and academic importance. METHODS: The research is based on an analysis of SARS, MERS, and COVID-19 and compares global policies. In this study, infectious disease emergency governance was divided into health policy management and economic factors. This study focused on planning and leadership before and after the outbreak of infectious diseases and how cooperation was achieved to monitor and respond to infectious diseases successfully. RESULTS and CONCLUSION: The limit of this study was that COVID-19 is a currently ongoing infectious disease with high uncertainty. Because it is an ongoing problem, only some data and statistics are reflected, and many limitations prevent a proper comparison under the same criteria as other infectious diseases. In addition, because continuous changes are expected, there is also room for infectious diseases to develop in a completely different pattern from the current situation, and continuous research must be accompanied in the future.

As our society and industry develop, disputes are becoming ever more complicated and diversified to the point that it is alleged that dispute resolution by court proceedings has certain limits and setbacks. Therefore, it is commonly suggested that mediation by a qualified mediator should come as an alternative method, and there have been many attempts to establish and provide mediation service in the courts and government authorities. To comply with a party's autonomy, which is the essential basis of mediation, and to promote the use of mediation, it is highly recommended that private mediation, rather than court-driven or administrative mediation, shall take the initiative. In the meantime, despite a number of academic research and attempts to increase the awareness and use of mediation nationwide, we have not yet seen meaningful developments due to the longstanding misunderstanding and discredit of mediation. In contrast, Italy has begun to revitalize mediation by enacting 'Legislative Decree No. 28/2020' following the 'Directive 2008/52EC' of the European Parliament and encouraging the so-called via-mediation policy. It is acknowledged to have significantly contributed to the development of private mediation in Italy and the increased use of mediation as a dispute resolution method. It shall be particularly noted that Italy's mediation proceedings have certain traits, including preliminary mediation meetings, mandatory involvement of legal counsel, and tax benefits for the settled cases by mediation. Italy's efforts would provide people with meaningful lessons and perspectives. As society strives to promote private mediation to distribute and utilize the judicial resources' inefficient ways, institutions need to develop practical measures to increase the number of civil and commercial disputes in the mediation proceedings. To that end, legislative efforts to enact relevant laws necessary to provide incentives to disputing parties and establish integrated education and certification programs to train qualified mediators need to start soon.

Recently, there is much abnormal traffic driven by several worms, such as Nimda, Code Red, SQL Stammer, and so on, making badly severe damage to networks. Meanwhile, diverse prevention schemes for defeating abnormal traffic have been studied in the academic and commercial worlds. In this paper, we present the structure of a stepwise intrusion prevention system that is designed with the feature of putting limitation on the network bandwidth of each network traffic and dropping abnormal traffic, and then compare the proposed scheme with a pre-existing scheme, which is a True/False based an anomaly prevention scheme for several worm-patterns. There are two criteria for comparison of the schemes, which are Normal Traffic Rate (NTR) and False Positive Rate (FPR). Assuming that the abnormal traffic rate of a specific network is $\beta$ during a predefined time window, it is known that the average NTR of our stepwise intrusion prevention scheme increases by the factor of (1+$\beta$)/2 than that of True/False based anomaly prevention scheme and the average FPR of our scheme decrease by the factor of (1+$\beta$)/2.

Background: This study aimed to investigate the effects of department satisfaction and career maturity on the perceived health status, relationship, and self-efficacy of dental hygiene college students based on Alderfer's existence-relationship-growth theory. Methods: We obtained convenience samples of dental hygiene students in Daejeon and Chungnam areas; 241 questionnaires were collected from 250 persons considering the dropout rate and used for the final analysis except for 9 careless responses. The differences in perceived health status, relationship, self-efficacy, department satisfaction, and career maturity according to general characteristics were analyzed using a t-test, one-way analysis of variance and Pearson's correlation coefficients. Moreover, structural equation modeling was performed to confirm the variables. GFI, AGFI,CFI, RMR, RMSEA, TLI, and NFI indices were calculated to verify the fitness of the path model. Results: There were significant differences in self-efficacy, department satisfaction, career maturity according to grade, and significant differences in academic performance for all variables except relationship. The school system also had a significant effect on department satisfaction. Perceived health status, relationship, self-efficacy, department satisfaction, and career maturity demonstrated statistically significant positive correlations (p<0.05). The factors affecting department satisfaction were relationship and self-efficacy. The indirect and total effects of perceived health status and relationship on career maturity were not statistically significant; however, the indirect and total effects of self-efficacy on career maturity were statistically significant. Conclusion: It is necessary to develop teaching methods according to student management plans for dental hygiene by comprehensively perceived health status, relationship, and self-efficacy affecting department satisfaction and career maturity.

The purpose of this study is to investigate the effects of service guarantees of tourist hotels on employees' perception of role clarity and customer orientation. Specifically, this study analyzed how the employees' perception of role clarity as a parameter, with the employees' reliability, guarantee-related communication, guarantee limitation, and organizational support as independent variables, affected the dependent variable, customer orientation. As a result of empirical analysis of employees in the first grade hotel in Seoul, it was analyzed that the higher the reliability of employees in service guarantee, the higher the communication and organizational support in the organization related to guarantee work, the higher the role clarity and perception level of employees. The higher the reliability, guarantee limitation and organizational support level of guarantee, the higher the customer orientation, but the guarantee-related communication did not show significant influence. The perception degree of role clarity of employees has a significant effect on customer orientation. According to those results of this analysis, this study examined the influence of each configuration of service guarantee of tourist hotel employees on customer orientation, and presented various academic and practical implications.
