Purpose: The study aims to identify the theme list and priority criteria of patient safety theme reports in South Korea. Methods: The survey was conducted twice, and the importance of each criterion and theme was measured on a nine-point scale using the Delphi technique by a panel of 19 patient safety experts. The criteria included severity, universality, preventability, and organizational-social impact. Descriptive statistics such as frequency, percentage, mean, standard deviation, median, and interval quartile range were used to analyze the data. Results: The parameters were assigned a weighted average of 35% for severity, 20% for universality, 30% for preventability, and 15% for organizational-social impact, respectively. The final top three rankings were surgery safety, blood transfusion safety, and medication safety. In addition to expert opinion, for the theme that is selected based on the priority ranking, one to five sub-topics can be derived from the theme based on the priority ranking, societal demands, or the yearly priority list of patient safety incidents. Conclusion: It is recommended that the official patient safety center distribute the report in the form of a summary that can be utilized nationwide at medical institutions, government institutions, and other places. Updates, as well as accumulated theme reports, will serve as the baseline data for the proposal of the system and for the policy designed to implement and improve institutions' safety practices as a standard of domestic patient safety practice guidelines.

More than twenty methods were suggested for Human Reliability Analysis (HRA) in the field of safety analysis for Nuclear Power Plants (NPPs). However, there is still a high uncertainty on the analysis and a difficulty in performing HRA. New methods and approaches are under studying to overcome such limitations of current HRA. This paper presents some results of study to analysis limitations of current HRA in viewpoint of user, i.e., HRA analyst. The limitation analysis was based on 89 human error events modeled in a Probabilistic Safety Assessment (PSA) project for NPPs in Korea. Total 17 specific limitations were identified and categorized into seven groups. Important analysis has also been undertaken to assess the order of priority among those limitations. Finally, seven requirements with priority ranking were generated for an advanced framework and methodology of HRA.

미국 환경보호청이나 세계보건기구를 포함한 유럽 등의 환경관리 기관에서는 1980년대 이후부터, 환경오염물질로 인한 인체 피해 정도를 위해도라는 확률의 개념을 도입하여 표현하고, 그 결과를 이용하여 오염물질 관리를 위한 기준치 등을 설정해 오고 있다(EPA, 1993). 국내에서도 이와 같은 위해성평가 연구가 10여년 이상 진행되어 왔고, 최근에는 환경오염물질의 위해성 평가나 관리정책의 중요성을 공히 인식하면서 이들 개념이나 연구결과들이 적절히 활용되고 있다. (중략)

This paper proposes an application methodology of AHP(Analytic Hierarchy Process) based decision making theory for improvement priority by assessment of various risk factors affecting on deterioration of water supply systems, as major social infrastructure. AHP method is organized with three level of hierarchy which is introduced for multi-criteria decision making in this study. In the first level, assessment outputs are calculated by AHP for each affecting factor. In the second level, criteria are estimated by using assessment results with respect to structural and environmental factors. Consequently, ranking decision is performed in the third level. In order to present the effectiveness, a proposed method is compared with FCP(Fuzzy Composite Programming) for decision making. Since the results of the proposed method show better performance with consistent results, it can be applied as an efficient information for the determination for improvement priority of the study infrastructure.

Background: Selecting priority occupational carcinogens is important for cancer prevention efforts; however, standardized selection methods are not available. The objective of this paper was to describe the methods used by CAREX Canada in 2015 to establish priorities for preventing occupational cancer, with a focus on exposure estimation and descriptive profiles. Methods: Four criteria were used in an expert assessment process to guide carcinogen prioritization: (1) the likelihood of presence and/or use in Canadian workplaces; (2) toxicity of the substance (strength of evidence for carcinogenicity and other health effects); (3) feasibility of producing a carcinogen profile and/or an occupational estimate; and (4) special interest from the public/scientific community. Carcinogens were ranked as high, medium or low priority based on specific conditions regarding these criteria, and stakeholder input was incorporated. Priorities were set separately for the creation of new carcinogen profiles and for new occupational exposure estimates. Results: Overall, 246 agents were reviewed for inclusion in the occupational priorities list. For carcinogen profile generation, 103 were prioritized (11 high, 33 medium, and 59 low priority), and 36 carcinogens were deemed priorities for occupational exposure estimation (13 high, 17 medium, and 6 low priority). Conclusion: Prioritizing and ranking occupational carcinogens is required for a variety of purposes, including research, resource allocation at different jurisdictional levels, calculations of occupational cancer burden, and planning of CAREX-type projects in different countries. This paper outlines how this process was achieved in Canada; this may provide a model for other countries and jurisdictions as a part of occupational cancer prevention efforts.

Employability has recently become the first target of the national higher education. Its model has been updated to catch the new trend of Industry 4.0. This paper aims at analyzing and ranking the determinants of undergraduate employability, focusing on business and economics majors in Ho Chi Minh City, Vietnam. In-depth interviews with content analysis have been primarily conducted to reach an agreement on a key group of factors: human capital, social capital, and identity. The Stochastic Fractal Search Algorithm (SFSA) is then applied to rank the sub-factors. Human capital is composed of three major elements: attitude, skill, and knowledge. Social capital is approached at both structural and cognitive aspects with three typical types: bonding, bridging, and linking. The analysis has confirmed the change of priority in employability determinants. Human capital is still a driver but the priority of attitude has been confirmed in the contemporary context. Then, social capital with the important order of linking, bridging, and bonding is emphasized. Skill, knowledge, and identity share the least weight in the model. It is noted that identity is newly proposed in the model but a certain role has been found. The findings are crucial for education strategies to enhance university graduate employability.

This research aimed to grasp the recognition of the amenity of the university students residing in Gyo-dong residential area in Gangneung city, the local residents residing in Daehag-ro which is near Jungang-ro in downtown and the public servants related to city development in Gangneung city office and thereby propose a plan to improve the amenity of Gangneung city. Based on the result of the research, the university student group around Gyo-dong residential area mostly recognized the amenity and the local residents around Daehag-ro showed insufficient recognition of the amenity and some of related public servants were found to be ignorant of the term amenity. Also, the priorities of amenity indexes identified from these 3 groups commonly showed aliveness requiring green lands and watercourses on top but 2nd priority of each group tended to be different from each other. Through the research result as above, we would like to propose the plan to improve as follows. First, the recognition of the concept of amenity is necessary. Second, green lands and watercourses that were selected by all of the 3 groups as ranking no. 1 should be secured. Third, the value of amenity resources should be evaluated. Gangneung city is a city where mountains and the sea are harmonized together granting abundant god blessed natural resources. But if Gangneung city would imprudently reclaims the excellent god blessed natural environment under the good title of city and housing lands development, its ranking in city competitiveness evaluations will be expected to continue descending. Therefore, as proposed in this research, the thing that has to be implemented with first priority for amenity Gangneung city is the execution of amenity policy to secure the identity of Gangneung city and the aspect of regulations or systems should also be pursued together with the policy.

본 연구에서는 교량의 내진보강방안을 합리적으로 결정하기 위하여 기존교량 및 보강된 교량의 지진하중에 대한 손상가능성을 이용하여 보강에 따른 내진성능 향상효과를 분석하였다. 교량의 내진보강에 따른 효과는 기존교량 및 보강된 교량에 대해 평가된 보강우선순위의 변화를 통하여 분석하였다. 이를 위하여 본 연구에서는 선행적으로 교량의 사용수명동안에 발생가능한 지진하중에 의한 지진취약부위의 손상확률과 손상으로 인해 예상되는 총 손실비용에 근거한 지진취약부위별 가중치를 이용하여 교량별 내진보강 우선순위를 결정할 수 있는 평가기법을 제안하였다. 제안된 평가기법의 타당성을 검증하기 위하여 다른 형식을 갖는 4개의 PSC 거더교를 대상으로 내진보강 우선순위를 평가하였다. 또한 각 지진취약부위별로 내진 보강된 교량에 대해 재평가된 순위지수를 기존교량에 대해 평가된 결과와 비교함으로써 각 교량별로 적용된 보강기법의 적합성을 검토하였다. 기존교량 및 보강된 교량에 대한 모의분석결과로부터 적용된 보강방안에 따라 해당취약부위의 손상가능성은 상당히 감소될 수 있으나 반면에 인접한 지진취약부위의 손상가능성은 증가되는 경향을 보이는 것으로 나타났다. 그러므로 기존교량에 대한 합리적인 보강방안을 결정하기 위해서는 내진보강에 따른 교량의 전체적인 거동특성변화에 따른 보강효과분석이 필수적으로 요구되며, 이는 본 연구에서 제안한 내진보강 우선순위 평가기법에 따라 기존교량 및 보강된 교량의 보강우선순위를 평가, 비교함으로써 효과적으로 수행될 수 있는 것으로 분석되었다.
