Objectives: Exposure Assessment for workplace hazards where the exposure level is below occupational exposure limits(OELs) has been performed without considering either the degrees of risk or exposure levels and has failed to lead to intervention in many cases. The objective of this study was to suggest and test an application framework for risk assessment methodology under the current exposure assessment system in Korea. Materials: First, we investigated the exposure assessment systems in Korea and other countries. To adopt some risk assessment techniques, we also analyzed risk assessment systems and compared them to exposure assessment systems. A few suggestions were made. We held a public hearing during an industrial hygiene conference and took surveys using a questionnaire. Results: The first suggestion was to implement the risk assessment and exposure assessment through a "one-stop" system. In that case, one expected question would be who has been doing the jobs so far. In most cases, industrial hygiene consulting services or laboratories have been performing exposure assessment for business owners. Business owners are required to perform risk assessment. As two different groups of people will be required to implement two things in a one-stop system, they need to share information. As an information vehicle to share information, commonly filed survey checklists were suggested. The second suggestion was to categorize exposure level into four groups instead of the current binary divisions based on OELs. In the risk assessment system, exposure level is divided into four groups utilizing the cut-points of 10%, 50%, and 100% of OELs. The same schema can be adopted in the exposure assessment system and different levels of requirements can be assigned for each group. The third suggestion was regarding the regulation system. To provide the suggestions some thrust toward being implemented in the field, changes should be made in the legal system. Two different types of new exposure assessment result reporting forms were suggested. Some investigations such as an ergonomic survey are officially accepted as risk assessment under the current legal system. A few items were suggested to be included in the exposure assessment result reporting to be accepted as risk assessment. A pilot study in two small factories was performed and pointed out the strengths and weakness of our suggestions. Conclusions: Discussions and studies on the improvement of the exposure assessment system have been held for decades and no tangible changes have yet been made. We hope this result can help realize healthy lives for workers in Korea.

최근 통행수요 관리 및 환경 정책의 일환으로 원격근무제의 확산이 적극 추진되고 있다. 이에 도시 교통 연구 분야에서도 원격근무의 효용을 검증하기 위한 다양한 실증연구들이 시도되고 있다. 그러나 아직까지 정책 평가와 학술 연구의 기초가 되는 원격근무의 정의와 현황에 대해서는 충분한 합의가 이루어지지 못하고 있다. 이에 본 연구는 원격근무의 사회적 영향 분석을 위한 기초연구로서, 원격근무 관련 개념의 정의를 정립하고, 가용 자료에 대한 검토를 통해 원격근무 유형별 보급률 및 시행수준을 파악하며, 이를 토대로 향후 보급률 수준을 예측하는 것을 목적으로 한다. 연구결과, 재택근무 보급률과 시행수준은 각각 0.5~1.1%와 0.2~0.5% 내외로, 센터근무 보급률과 시행수준은 각각 0.2%와 0.1% 내외로 나타났다. 또한, 변이-할당 분석을 통해 도출된 2020년 수도권의 재택근무 보급률은 약 1.3% 정도로 현재 수준과 큰 차이를 보이지 않았다. 결과적으로, 현재 원격근무 보급률은 최근 언론을 통해 보도된 수치(10~20%)에 비해 매우 낮은 수준이며, 향후 전망 또한 정부 목표치(30~45%)에 비해 크게 낮을 것으로 예측되어 적극적인 권장 정책이 개입되지 않은 이상 정부 목표는 달성되기 어려울 것으로 판단된다.

A novel parallel three-level zero voltage switching (ZVS) DC converter is presented for medium voltage applications. The proposed converter includes three sub-circuits connected in parallel with the same power switches to share load current and reduce the current stress of passive components at the output side. Thus, the size of the output chokes is reduced and the switch counts in the proposed converter are less that in the conventional parallel three-level DC/DC converter. Each sub-circuit combines one half-bridge converter and one three-level converter. The transformer secondary windings of these two converters are connected in series in order to reduce the size of output inductor. Due to the three-level circuit topology, the voltage stress of power switches is equal to $V_{in}/2$. Based on the resonant behavior by the output capacitance of power switches and the leakage inductance (or external inductance) at the transition interval, each switch can be turned on under ZVS. Finally, experiments based on a 2 kW prototype are provided to verify the performance of the proposed converter.

In most of the world, the current trend in information technology is for open data movement that promotes transparency and equal access. An opposite trend is observed in China, which has the world's largest Internet population. The country has implemented sophisticated cyber-infrastructure and practices under the name of The Golden Shield Project (commonly referred to as the Great Firewall) to limit access to popular international web services and to filter traffic containing 'undesirable' political content. Increasingly, tech-savvy Chinese bypass this firewall and use Twitter to share knowledge on censorship circumvention and encryption to collectively troubleshoot firewall evasion methods, and even mobilize actions that border on activism. Using a mixed mythological approach, the current study addresses such networked knowledge sharing among citizens in a restricted web ecosystem. On the theoretical front, this study uses webometric approaches to understand change agents and positive deviant in the diffusion of censorship circumvention technology. On policy-level, the study provides insights for Internet regulators and digital rights groups to help best utilize communication networks of positive deviants to counter Internet control.

The purpose of this study was to suggest improvements to the related regulations of community facilities for community activation by analyzing the current situations and problems of the related regulations of community facilities in apartment housing complexes. To provide the improvement, we took contents analysis about community facilities for activation of the community. We interviewed a national civil servant, a local civil servant and an employee at Daiwa house in Japan, and conducted a field survey of community facilities in Japan during July 20-23, 2010. The main findings of this study were as following; there were problems that the related regulations of community facilities didn't reflect the characteristics of residents and community. Therefore, it was necessary to improve the related regulations to reflect the characteristics of residents and community. So the current standards were revised by local government ordinance. Community centers were not installed in each housing complex, but were installed to share with several housing complexes. Regional community centers are needed for activation of regional communities as with the Baycore Civil center.

In recent years, NCAP regulations of many countries have induced automaker to improve the vehicle crashworthiness. But, the current NCAP regulations don't cover all types of traffic accidents. And rapid-increasing market share of compact cars and SUVs has brought for both consumer and automaker to pay more attention on crash compatibility. So, many countries have tried to develop the new crash test mode and update the present crash test mode. Especially, Euro NCAP has been developing a new impact protocol of the car-to-car frontal offset impact including the crash compatibility assessment. There are plans to introduce this new protocol in 2020, and it will be replaced the current Euro NCAP frontal offset impact. The test dummy in the front seats of this new test mode will be changed from 50% Hybrid-III male to 50% THOR male. This paper will address the vehicle responses, the occupant responses and the vehicle compatibility performance from a full vehicle crash test using the new car-to-car frontal offset test protocol of Euro NCAP.

Objectives: This paper discusses the current contexts of the collaboration between public health centers(PHCs) and community partners for health promotion. Then it suggests directions for the development and enhancement of the collaboration. Methods: The discussion in this paper is based on key literature on community health promotion, including literature reviews and case reports. Results: PHCs are mostly engaged in networking and cooperation rather than collaboration with the community. A typical pattern of cooperation is where PHCs provide healthy-setting types of programs to the community in single-partnered relationships. Current cooperation rarely involves co-planning by a multi-partnered partnership, and is greatly influenced by the interest of PHC directors and PHC performance evaluation indicators. Systems change is recommended to foster collaboration for community health promotion. Such change involves: shared understanding of health promotion and collaboration, inclusion of collaboration mechanism in public health governance, leadership development, capacity enhancement of all partners. role definition of PHCs for community collaboration, and development of collaborative system, at the least. Conclusions: At this point where collaboration should be more than rhetoric, multi-faceted, intersectoral, and concurrent approaches are required to create discourses, to develop cases, and to share experience for actual realization of collaboration for community health promotion.

CEO duality and its impact on firm performance represent one of the most contentious issues in both academia and business. This study, therefore, aims to examine the moderating role of CEO duality in the relationship between intellectual capital Efficiency (human, structural, relational, Capital Employed, and Innovation) and firm performance (earnings per share and Tobin's Q) among Jordanian companies. The study sample consists of services listed companies on Amman Stock Exchange. The study used panel data for the period 2014-2018 with a sample size of 230 observations. SPSS software was used to analyze the collected data. The regression results indicate a significant relationship between, IC and firm performance. When CEO Duality is incorporated into the model as a moderator, there is an increase in the R² by 7.9%. The findings from this study expand the theoretical underpinning of corporate governance research by identifying the performance implications of CEO duality within the Jordanian context. It also contributes significantly to the literature review about the current status of the practices taken in the intellectual capital components efficiency among companies listed on the Amman Stock Exchange. Findings from this study also provide contributions to the concerned policymakers such as the Ministry of Finance, Securities Commission, and Amman Stock Exchange in Jordan, to improve the current policies related to intellectual capital efficiency.
