The policy proposal by the current Korean government that proposes flexible overtime rules is causing social controversy. This study has explored the 612 experts' opinions on the occupational safety and health impacts of the policy using an online self-report survey. They expected short-term overwork (87.25%), overwork inequality (86.44%), irregular working hours (84.31%), chronic overwork (84.15%), long working hours (83.66%), and unpredictability of working hours (81.86%) as a result of the policy change. They also responded that the policy change would increase industrial accident deaths (87.25%), mental illnesses (87.09%), deaths due to overwork or cardiovascular diseases (83.84%), and accidents (83.33%). They disagreed that the government's flexibilization policy, while agreeing that the necessity of policies on regulating night work (94.77%), guaranteeing wages to eliminate overtime (90.36%), establishing working time regulations for the bogus self-employed (82.84%), and applying the 52-hour workweek system to all workplaces (76.47%). These expert opinions are consistent with previous research on the health effects of working hours.

This study examines the main elements, concepts, and directions of 'cultural accessibility' in the field of cultural arts education through the French case. Above all, 'cultural accessibility' is viewed from the perspective of the problems of 'social exclusion' and the corresponding 'participation'. We discuss strategies for applying 'cultural accessibility' through French policy discussions. France is implementing this consistent policy structure through the development of its local self-government system. We first look at the current status of French cultural policy and cultural accessibility, and the participation. Next, we will discuss separately into the cultural arts education of the central government and those of local governments. For application to Korea, we propose the application of education to apply 'culture of public values', the establishment of autonomy in cultural arts education, and the application of a dual strategy for public advocacy.

Background: Infection prevention and control (IPC) to manage healthcare-associated infection (HCAI) has emerged as one of the most significant public health issues in Korea. The purpose of this study is to draw implications in IPC policies by analyzing the context, process, and major actors in policy development and comparatively analyzing IPC policy contents of Korea with three other countries. Additionally, IPC policies were analyzed in the context of coronavirus disease 2019 (COVID-19) to provide implications for future pandemics and HCAI events. Methods: This study incorporates a qualitative approach based on document and content analysis, applying codes and thematic categorization. IPC policy contents are comparatively analyzed by adopting the concept model, developed by the World Health Organization, which consists of core components of IPC structure at the national and facility level. Results: National IPC policies were developed within a complex social and political context, through the involvement of various stakeholders. IPC policies in Korea place a high emphasis on establishing IPC programs and built environments in healthcare facilities, whereas there were potentials for improvement in policies involving patients and promoting a safety culture. IPC policies, which currently focus on general hospitals and certain functions of hospitals, should further be expanded to target all healthcare facilities and functions, to ensure more efficient and sustainable IPC responses in the current and future disease outbreaks. Conclusion: IPC is a complex policy arena and lessons learned from the analysis of existing policies in the context of COVID-19 should provide valuable strategic implications for future policies.

본 논문에서는 이종 접속망에서 이동 단말기 및 접속망 상태 등에 따라 가변적으로 변하는 자원관리 기능을 이동 단말기의 핸드오버 처리에 적용함으로써 최적의 QoS를 보장할 수 있는 정책기반 자원관리 프레임워크를 제안하였다. 본 논문에서 제안한 정책기반 자원관리 프레임워크의 성능을 평가하기 위하여 중첩된 이종 접속망간에서 발생하는 핸드오버시 최적의 셀을 선정하기 위한 가중치 정책을 적용했을 경우, 멀티미디어 서비스 세션의 수가 증가할수록 전송 지연이 현저히 향상된 것으로 분석되었다. 이는 서비스 중인 접속망에서 QoS 저하가 발생할 경우에 최적의 접속망으로 핸드오버가 수행되어 현재 서비스에 가장 적합한 이종 시스템으로의 서비스 절체가 이루어지므로 서비스의 연속성을 최대한 보장할 수 있다.

Purpose: This study aims to analyze the factors affecting the agenda-setting process and the formation process of school-based mental health policies by applying a policy stream model. Methods: For this purpose, Kingdon's policy stream model was used as the analytical framework. Results: First, when establishing a school-based mental health policy, the agenda was set going through unpredictable and nonlinear changes. Second, for the school-based mental health policy to be selected onto the agenda and to be developed and implemented as an actual policy, the role of policy makers was considered most important in the process. Third, the policy window for school-based mental health policy was closed around the year 2013. Finally, an analysis of the school-based mental health policy stream identified two key features. One is that the school-based mental health policy first emerged when school violence prevention policy expanded its scope into relevant neighboring policies. The other is that the school-based mental health policy has taken shape through a linear decision-making process (being put on the government's agenda, searching for an alternative, selection, and implementation) during the policy implementation period after it has been selected as an alternative policy. Conclusion: Conclusions can be summed up as follows. The school-based mental health policy needs continuous development and improvement in case the window for the policy may open in the coming future. The government's support is needed to draw policy makers' interest and participation who play the biggest role in establishing policies.

This paper investigates how public opinion has affected the United States Senate's votes on arms control treaties. Applying multilevel modeling with post-stratification to national polls, this paper produces estimates of state-level opinion on both the New Strategic Arms Reduction Treaty of 2010 and the Comprehensive Test Ban Treaty of 1999. Using these estimate, this paper examines the relationship between public opinion and the Senate's votes on the treaties. This paper finds that the influence of public opinion was mostly significant but indirect. These findings indicate that some version of the delegate model of representation is more applicable to foreign policy making in Congress.

By applying Systems Simulation technique, this paper aims to investigates the dynamics underlying the coevolution of IT(information technology) and the society. Particularly, a series of basic questions are explored to answer by developing a simulation model for the mechanisms underlying the 'hype curve' ever occurring in the course of technology diffusion into society: First, why hype curve appears in the process of technology and society coevolution. Second, how to enhance the tapering level at the final stage of coevolution. Third, what are the key policy leverages and when is the right time for the policy intervention. As now, inflated expectations regarding ubiquitous information technology (u-IT) are growing very fast and higher than those for the previous technologies, which would result in overshoot followed by collapse of visibility and thus incur tremendous amount of social costs. In this regard implications drawn from this study perhaps give some insights not necessarily to the academics but also to the practitioners and policy makers facing the advent of u-IT as a new emerging horizon of information society.
