Objectives: The purpose of this study was to evaluate the exposure to arsenic in preventive maintenance (PM) engineers in a semiconductor industry by detecting speciated inorganic arsenic metabolites in the urine. Methods: The exposed group included 8 PM engineers from the clean process area and 13 PM engineers from the ion implantation process area; the non-exposed group consisted of 14 office workers from another company who were not occupationally exposed to arsenic. A spot urine specimen was collected from each participant for the detection and measurement of speciated inorganic arsenic metabolites. Metabolites were separated by high performance liquid chromatography-inductively coupled plasma spectrometry-mass spectrometry. Results: Urinary arsenic metabolite concentrations were 1.73 g/L, 0.76 g/L, 3.45 g/L, 43.65 g/L, and 51.32 g/L for trivalent arsenic (As<SUP>3+</SUP>), pentavalent arsenic (As<SUP>5+</SUP>), monomethylarsonic acid (MMA), dimethylarsinic acid (DMA), and total inorganic arsenic metabolites (As<SUP>3+</SUP> + As<SUP>5+</SUP> + MMA + DMA), respectively, in clean process PM engineers. In ion implantation process PM engineers, the concentrations were 1.74 g/L, 0.39 g/L, 3.08 g/L, 23.17 g/L, 28.92 g/L for As<SUP>3+</SUP>, As<SUP>5+</SUP>, MMA, DMA, and total inorganic arsenic metabolites, respectively. Levels of urinary As<SUP>3+</SUP>, As<SUP>5+</SUP>, MMA, and total inorganic arsenic metabolites in clean process PM engineers were significantly higher than that in the nonexposed group. Urinary As<SUP>3+</SUP> and As<SUP>5+</SUP> levels in ion implantation process PM engineers were significantly higher than that in non-exposed group. Conclusion: Levels of urinary arsenic metabolites in PM engineers from the clean process and ion implantation process areas were higher than that in office workers. For a complete assessment of arsenic exposure in the semiconductor industry, further studies are needed.

Much attention has been given to necessity of ex-ante analysis that focuses on feasibility of governmental projects before their implementation. However IT programs of public sectors have less experienced feasibility studies compared to other public programs. National Finance Act which has been effective as of 2007 finally provides a framework of feasibility study(ex-ante analysis) of public IT projects. This study suggests that performance management of IT programs needs a life-cycle evaluation especially focusing on the ex-ante analysis. The recommendations that this paper proposes to make ex-ante evaluation effectively function are, life-cycle evaluation system, contingent evaluation framework according to types of projects, and appropriate utilization of results of evaluation.

감염병의 발생은 20세기 이후 기후변화, 도시화, 이동 편리성으로 증가하고 있다. 세계 각국은 COVID-19 대응에 있어서 큰 혼란을 겪었다. 한편 팬데믹 수준의 감염병 재난은 방역당국과 다양한 사회 주체의 협력이 있어야 좀 더 효과적으로 대응할 수 있음을 알았다. 이에 우리가 최근 경험하였던 감염병 MERS와 COVID-19의 초기 대응사례를 비교 분석하였다. 특히 재난관리에 있어서 다양한 사회주체의 참여를 기반으로 하는 협력적 거버넌스를 바탕으로 비교 분석하였다. 협력적 거버넌스는 네트워크, 책임과 역할, 참여와 협조가 잘 이루어질 때 보다 효과적이다. 이에 3가지 핵심 요소를 가지고 감염병 재난대응 사례를 비교 분석하고 이를 근거로 효과적인 민관협력 활성화 방향을 제시하였다. 먼저, 정부는 기존 재난관련 네트워크조직에 대한 지원을 강화해야 한다. 또한 스마트사회 기반의 새로운 네트워크 구축이 필요하다. 두 번째, 재난관련 조직 및 참가자를 위한 재난교육 훈련의 확대, 중간지원조직의 강화, 이를 위한 정부의 역할 확대를 제시하였다. 마지막으로 의료인 중심의 재난관련 민간조직의 구성 및 기업의 참여확대를 위한 시스템 강화의 필요성을 주장하였다. Since the 20th century, the incidence of infectious diseases has been increasing owing to climate change, urbanization, and the convenience of movement. Countries worldwide have experienced great confusion in their response to COVID-19. At the same time, we also found that we can respond to pandemics more effectively when quarantine authorities and various social entities cooperate. Therefore, we compared and analyzed the early response cases of MERS and COVID-19 that we recently experienced. In particular, a comparative analysis was conducted on cooperative governance based on the participation of various social entities in disaster management. Cooperative governance is more effective when networks, roles and responsibilities, participation, and cooperation are well established. Accordingly, the cases of disaster response for infectious diseases were compared and analyzed with three key factors, and based on these, effective directions for revitalizing public-private partnerships were suggested. They are as follows: First, the government should strengthen support for existing disaster-related network organizations. Additionally, it is necessary to build a new network based on a smart society. Second, it is important to expand disaster education and training for disaster-related organizations and participants, strengthen intermediate support organizations, and expand the government's role in these areas. Finally, we present the importance of strengthening the system to form disaster-related private organizations that are centered on medical personnel, and expanding corporate participation.
