도심지 개착식 굴착공사 중 발생하는 붕괴사고는 공사장 내에서의 인명 및 물질적 피해를 불러일으킬 뿐만 아니라, 공사장 주변의 지반침하로 인한 도로함몰 및 시설물 피해를 유발한다. 따라서, 도심지에서 개착식 굴착공사를 수행함에 있어서, 계획, 설계 및 시공의 건설 전체 단계에서 굴착공사 붕괴 방지를 위한 철저한 대비가 필요하다. 본 연구에서는 이와 같은 개착식 굴착공사 중 붕괴사고 예방을 위해, 중점적으로 관리되어야 할 우선 요소 결정 연구를 수행하였다. 먼저, 과거 흙막이 굴착공사의 사고사례 조사결과를 분석하고, 전문가 합의에 의한 의사결정 방법인 델파이 기법을 이용하여 붕괴 유발 요소에 대한 중요도를 산정하였다. 그 결과, 지하수 처리, 지반조사의 부실, 시공상의 불안정 등이 흙막이 공사 붕괴 예방을 위한 중점 관리 요소로 도출되었다.

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.

The purpose of this study is to suggest the general education contents for undergraduate students at engineering related departments through need analysis in order to develop creative and integral talents. For this study, the need analysis was conducted by using focus group interviews, Borich's educational need equation and the Locus for Focus Model, and highly ranked priorities on both methods proposed as the highest priorities. As a result, 'drawing up a letter of self-introduction and a portfolio', 'understanding fields', 'understanding careers related to the major', 'presentation skills', 'knowledge for certificated exams', 'method to deduct creative ideas' were high on the list of top five priorities. The selected items by Locus for Focus Model show that undergraduate students at engineering related departments need general education contents associated with career development and communication by priority.

The purpose of this paper is to decide priorities of policy-objectives and support measures related to the $6^{th}$ industrialization of agriculture, and prepare policy-objectives and alternatives to contribute to maintaining and promoting the community through creation of more jobs and added value. We used the Analytic Hierarchy Process (AHP) to reflect the experts' opinions about objectives, means and priorities of the $6^{th}$ industrialization of agriculture. The important objectives of the 6th industrialization of agriculture were to create jobs, to increase added values, and to maintain and activate the community. The results showed that the most important objectives for the $6^{th}$ industrialization of agriculture were maintaining and activating the community, expanding added values and creating employment in order. Policy means to achieve these objectives were financial support, human resource training & consulting, research & development, and marketing. The decision-makers determined marketing as the most important among the policy means to achieve the objectives of the $6^{th}$ industrialization.

The objective of this study is to propose a new procedure to synthesize the multi-experts priorities in AHP. To aggregate the multi-experts priorities, in this paper, we suggest a way which Decision Maker can exclude outlier matrix from group using the concept of the compatability and we introduce Delphi method to use compatability in AHP. Some numerical example are shown to illustrate the procedure.

Purpose: This study compared nursing frequency, nursing time, and nursing intervention priorities depending on the method of neonatal induced hypothermia. Methods: We observed 15 neonatal subjects receiving therapeutic hypothermia for 3 days each. Forty-five nurses experienced with nursing neonatal patients under therapeutic hypothermia provided responses about nursing intervention priorities. Analyses with the chi-square, the Fisher exact test, the paired t-test, the Wilcoxon signed rank test, and the Wilcoxon rank-sum test were performed on the data using SAS version 9.4. Results: The frequency of nursing activities was higher for selective head therapeutic hypothermia (SHTH) than for systemic therapeutic hypothermia (STH), and nursing time was also significantly longer. In terms of nursing intervention priorities, there were priority differences in "risk for ineffective thermoregulation" and "risks for impaired skin integrity" for SHTH compared to STH. Conclusion: Since SHTH for neonatal therapeutic hypothermia requires more nursing time and frequent nursing activities than STH, STH is therefore recommended if the therapeutic efficacy is similar. Appropriate nursing personnel should be allocated for neonatal SHTH nursing. Nurses should be aware of nursing interventions for therapeutic hypothermia as the priorities are different for different methods of neonatal therapeutic hypothermia.

With the increased interest in renewable energy, various hydrogen production technologies have been developed. Hydrogen production can be classified into green, blue, gray, and pink hydrogen depending on the production method; each method has different technical performance, costs, and CO₂ emission characteristics. Hence, selecting the technology priorities that meet the company strategy is essential to develop technologically and economically feasible projects and achieve the national carbon neutrality targets. In addition, in early development technologies, analyzing the technology investment priorities based on the company's strategy and establishing investment decisions such as budget and human resources allocation is important. This study proposes a method of selecting priorities for various hydrogen production technologies as a specific implementation plan to achieve the national carbon neutrality goal. In particular, we analyze key performance indicators for technology, economic feasibility, and environmental performance by various candidate technologies and suggest ways to score them. As a result of the analysis using the aforementioned method, the priority of steam methane reforming (SMR) technology combined with carbon capture & storage (CCS) was established to be high in terms of achieving the national carbon neutrality goal.

Objectives: There is requirement to select candidate materials for chronic inhalation/carcinogenicity testing, so we would like to set the priority of candidate materials. Methods and Results: We recommend the priorities for candidate materials based on the chemicals stipulated in the Occupational Safety and Health Act(OSHAct) and the Toxic Chemicals Control Act(TCCA) in Korea. Conclusions: We presented candidate chemicals consisting of solids(powders), gases and liquids(Such as organic solvents) with priorities.
