This study is to investigate the related materials such as domestic law regulation, research paper, research report, and the other material, and to suggest suitable counter measures, to find out hazard degree for its works of workers and work place through direct survey, in order to determine risk score of each hazardous work which is designated by the Government, without consideration of labour's consciousness against risk level at a site. Therefore, a new questionnaire survey related to the decision of risk level are made and distributed to find out what risk level each worker recognizes. Also, the authors tried to approach reasonable conclusions after discussing reasonability of qualification standard and improving ideas of worker at hazardous work places with worker, faculty member, H&S manager, labour union. And the results show hazard degrees by each work kind of the above: 3.75 for working with machinery, 3.7 for steel structure, 3.5 for operation of tower crane, 3.51 for retaining wall, 3.85 for form work, 3.46 for scaffolding are obtained. This quantified risk can be applied to establishing a reasonable system to keep safe against hazardous works.

국내 건설현장은 아직까지 근로자를 위한 많은 편의 시설들이 부족한 형편이며, 이러한 것들은 궁극적으로 근로자들 스스로 안전의식이 결여되어 건설재해 발생에 악영향을 미치고, 이것은 건설현장에 대한 3D기피 현상을 확산시켜 인력난을 겪고 있는 현실이 더 가중될 것이다. 본 연구에서는 이러한 문제점의 해결방안을 인간본성의 원천에서 찾아 내어 해결하기 위해 근로자들의 감성을 일깨우는 감성안전문화시설들을 현장에 적용하였다. 그 결과, 감성안전문화시설들은 근로자들에게 작업 중 안전의식을 조성시키는 긍정적인 측면이 있었다. 또한 이러한 시설물들은 근로자들로 하여금 조직의 일원으로서 느끼게 했으며, 작업능률에 큰 도움이 되는 것으로 조사되었다.

Objectives: Since information on biological factors in the workplace are currently lacking, I wanted to create a handbook of these factors that would be viewable at a glance as a means to more effectively prevent occupationally-infected diseases. Proper information on biological hazards in the workplace allowing the appropriate recognition of the harmful factors is desperately needed. Methods and Results: In this study, I intended to create a high-utility handbook of biologically hazardous agents in the workplace. To ensure its effectiveness, information and references about biologically hazardous agents in the workplace were analyzed and classified and pathogen safety data sheets(PSDS) sourced from the Public Health Agency of Canada were included. I intended to make it accessible from the point of view of workers and their employers. A more effective classification system of occupational infectious diseases is presented, and biologically hazardous agents were classified according to occupations, industries, infectious diseases, and so on. The handbook consists of 60 major kinds of biologically infectious occupational factors that are expected to be generated in workplaces in Korea, and are focused on practical utility. The pathogen safety data sheets(PSDS) of 192 species were also included. To allow more effective management, domestic and foreign laws and regulations are presented. Conclusions: This case report presents general information on the history and contents of the handbook and PSDS, it will also be useful in workplaces if download from the homepage of OSHRI, KOSHA(oshri.kosha.or.kr/bridge?menuID=901).

The objective of this study was to investigate the problems and benefits associated with the implementation of HACCP on livestock product of plants in Korea. The survey was carried out by randomly selecting 115 HACCP accredited meat processing plants, all across the country. A total of 105 complete responses were selected for analysis. The results were as follows: approximately 60% of the respondents employed less than twenty workers. The average period of operating HACCP system was 3.4 years. The respondents replied that the major incentive to implement the HACCP system was to improve hygiene management ability. More than half of the respondents (59.05%) claimed that the implementation of the HACCP system cost less than 400 million won, and the highest investment in terms of cost was the freezer/refrigerator. In the preparation period taken to implement the HACCP system, the 6-12 mon category had the highest percentage (55.24%). Most respondents replied that there was an increase in the customer satisfaction, plant image and turnover, after HACCP implementation (p<0.05). A total of 98.09% of respondents had the opinion that their plant workers had improved in their understanding of food hygiene by HACCP implementation (p<0.05). Approximately 79% of respondents indicated that customer complaints decreased, as a result of HACCP implementation.

Decommissioning process of nuclear facilities consist of a sequence of problem solving activities, because there may exist not only working environments contaminated by radiological exposure but also industrial hazards such as fire, explosions, toxic materials, and electrical and physical hazards. Therefore, not a few countries in the world have been trying to develop appropriate counter techniques in order to guarantee safety and efficiency of the process. In spite of that, there still exists neither domestic nor international standard. Unfortunately, however, there are few workers who experienced decommissioning operations a lot in the past. As a solution, it is quite necessary to utilize experts' opinions for risk assessment in decommissioning process. As for an individual hazard factor, risk assessment techniques are getting known to industrial workers with advance of safety technology, but the way how to integrate those results is not yet. This paper aimed to find out an appropriate technique to integrate individual risk assessment results from the viewpoint of experts. Thus, on one hand the whole risk assessment activity for decommissioning operations was modeled as a sequence of individual risk assessment steps which can be classified into two activities, decontamination and dismantling, and on the other, a risk assessment structure was introduced. The whole model was inferred with Fuzzy theory and techniques, and a numerical example was appended for comprehension.

The 52-hour workweek policy in Korea is a system that limits the maximum working hours per week to 52 hours including holiday work, which has been treated separately from overtime work during a week. Although this policy is designed to improve the quality of life and create jobs, it may also reduce the income of some workers. In general, it can be assumed that reduced working hours increase consumption at home. This study analyzed the effect of the 52-hour work policy on meat consumption patterns with the ordered logit model. Major factors considered in this study include working hours, income, and consumption frequency. It distinguished domestic and workplace consumption. The results show that the policy has had an impact on meat consumption patterns both at home and at work. If there is no change in income and only the working hours decrease, meat consumption in households increases. On the other hand, if both income and working hours decrease, household meat consumption decreases. Moreover, reduced working hours decrease the frequency of office happy hour and meat consumption in the workplace. However, the 52-hour workweek policy applies only to workers working more than 52 hours per week; thus, it is difficult to determine the overall effect of the policy on national meat consumption patterns.

Compared to operational wastes, nuclear power plant (NPP) decommissioning wastes are generated in larger quantities within a short time and include diverse types with a wider range of radiation characteristics. Currently used 200 L drums and IP-2 type transport containers are inefficient and restrictive in packaging and transporting decommissioning wastes. Therefore, new packaging and transport containers with greater size, loading weight, and shielding performance have been developed. When transporting radioactive materials, radiological safety should be assessed by reflecting parameters such as the type and quantity of the package, transport route, and transport environment. Thus far, safety evaluations of radioactive waste transport have mainly targeted operational wastes, that have less radioactivity and a smaller amount per transport than decommissioning wastes. Therefore, in this study, the possible radiation effects during the transport from NPP to disposal facilities were evaluated to reflect the characteristics of the newly developed containers and decommissioning wastes. According to the evaluation results, the exposure dose to transport workers, handling workers, and the public was lower than the domestic regulatory limit. In addition, all exposure dose results were confirmed, through sensitivity analysis, to satisfy the evaluation criteria even under circumstances when radioactive materials were released 100% from the container.

본 논문은 국내외 경제 활동은 지역 간 이동성에 미치는 영향성을 연구한다. 동유럽에서는 인적 자원과 수요가 여전히 부족하다. 특히 우크라이나 인들은 희소 한 지역을 보충하기 위해 폴란드 노동 시장에 진출했다. 결과적으로 우크라이나의 폴란드 수요와 공급은 불균형하다. 최저 임금 인상은 고용주에게 지속적인 압력을 가하고 있다. 따라서 구직자의 경제 활동 비율,y=AX²+B,(x=정착)형태의 회귀 방정식을 사용하여 곡선 간의 관계를 파악할 수 있다. 이주한 국내외 노동자에 따르면 경제 활동은 지역 인구를 늘리는 것이 아니라 인근 대도시의 정착민이 더 비례한다. 실증적 분석에 따르면 인적 자원 허브가 대도시 및 산업으로의 이동이 증가한 것으로 나타났다. 허브 A 국가는 4 차 재산업에서 이동성을 위해 만들어졌으며 다른 도시에서와 동일한 재산업화 (N₂)가 인근 인력을 유치했지만 정착하지는 못했다. 결국 N₁과 N₂의 허브 관계는 이동 관계이다. 임금 불평등이나 긍정적인 후생 단절로 인해 노동자들은 공장 지역이 아니라 인근 도시에 정착하거나 국경 사이의 통근이 허브 중심 도시로 가기 쉽다. 그러나 이것은 인공지능 시대의 상대적으로 일시적인 정착민들로부터 대두된다.
