본 연구는 국제원자력기구(International Atomic Energy Agency: IAEA)의 원자로정보시스템(Power Reactor Information System: PRIS)에서 제공하는 원자로 운전실적지표를 이용하여 원전의 안전성에 미치는 기술적 비기술적 요인의 역할을 분석한다. 이를 위해 안전성의 척도로 원전의 고장정지에 따른 발전손실률 (FLR: forced loss rate)을 사용했다. 1970년부터 2015년까지 전 세계에서 운영된 모든 원전으로 구성된 패널자료를 통해 분석한 결과, 기존 연구와 마찬가지로 원전의 전반적인 기술수준과 정비기술수준이 향상될수록 FLR이 하락하는 사실을 확인했다. 하지만 1986년 체르노빌 원전 사고 이후 기술적 요인이 통제된 FLR은 유의적으로 상승했다. 이는 원자력발전사업자가 체르노빌 사고 이후 원자력안전을 위해 보다 많은 기회비용을 지불하고 있다고 해석된다.

본 연구는 산재보험의 재해보상이 산재 여부에 따라 급여 수급을 전액받거나 혹은 전액 받지 못하는 체계로 인해 산재여부에 대한 판정의 복잡성과 갈등의 요소가 내재되어 있는 문제점의 개선에 초점을 두고 있다. 재해보상형태는 초기 원인주의에 입각한 사용자의 배상책임에 따라 배상 정도가 결정되었으나, 이후 무과실책임주의로의 전환과 재해인정범위의 확대 과정을 거치게 되었다. 이러한 발전은 재해인정에 있어서 All or Nothing 원칙 강화로 이어지게 된다. All or Nothing 원칙이 상당한 논란의 소지가 있음에도 부분인정제도를 도입하기 어려운 이유는 행정적 복잡성을 더욱 심화시키는 점에 있다. 따라서 선진국에서는 사회보장의 종합적 차원에서 보편적 보장을 통해 전체인정제도의 한계를 극복하고 있다. 하지만 한국의 경우 재해로 인한 비용발생이나 소득손실에 대해 종합적 보장체제가 이뤄져 있지 않아 산재인정과 관련된 논란이 심해질 우려가 있다. 따라서 보상차등화의 취지와 논리 수용을 통한 제도개선과 더불어 장기적으로는 종합적인 재해보상 체제 구축이 요구된다.

The Fukushima accident reveals the vulnerability of existing active nuclear power plant (NPP) design against prolonged loss of external electricity events. The passive safety system is considered an attractive alternative to cope with this kind of disaster. Also, the passive safety system enhances both the safety and the economics of NPPs. The adoption of a passive safety system reduces the number of active components and can minimize the construction cost of NPPs. In this paper, reflecting on the experience during the development of the APR+ design in Korea, we propose the concept of an innovative Power Reactor (iPower), which is a kind of passive NPP, to enhance safety in a revolutionary manner. The ultimate goal of iPower is to confirm the feasibility of practically eliminating radioactive material release to the environment in all accident conditions. The representative safety grade passive system includes a passive emergency core cooling system, a passive containment cooling system, and a passive auxiliary feedwater system. Preliminary analysis results show that these concepts are feasible with respect to preventing and/or mitigating the consequences of design base accidents and severe accidents.

This survey is to compare the the number of accidents which were occurred in 24 construction companies with the average accident in construction industry. The number of accidents in 24 companiesis is lower than the average accident, then it is classified "save", otherwise it is classified "loss". This survey is conducted to have top management be interested and invest for safety by recognizing that safety management could be profit for the company. The result of this survey is as follows : The total save amount in 1992 is 44,780mi11ion Won and average is 1,870mi11ion Won, with being 11, 200mi11ion Won by reduction amount of deaths and 33,580mi11ion Won by reduction amount of injuries. In 1993 the total is 33,330mi11ion Won and average is 1,390mi11ion Won, and in 1994 the total is 38, 720mi11ion Won and the average is 1,610mi11ion Won. This result is save amount of workmen's compensation insurance with excluding the indirect costs for accidents. The company which ranked the highest save amount is B Construction Company with being 15.1 billion Won and the next is A Construction Company during 3 years. The Company which ranked highest percentage of save amount to sales amount is Q Heavy industry with being 0.359% and the next is B Construction Company during 3 years.pany during 3 years.

과거 건설공사의 목표는 원가절감과 공기단축을 통한 효율성 증진이라고 하여도 과언이 아닐 것이다. 그러나 이에 비하여 안전관리는 오랜 기간 소홀히 되어온 것이 사실이다. 이러한 이유로 안전관리는 원가나 공기 측면에 비하여 많이 뒤떨어져 있는 상황이다. 그럼에도 불구하고 현재 건설공사에서 이루어지고 있는 안전관리는 과거에 비하여 커다란 발전이 없는 상황이다. 단지 안전기술 기준과 규칙 등의 지식 중심의 사후 처리에 집중되어 상황이며, 여전히 비효율적인 측면이 많이 존재하고 있는 실정이다. 비록 과거와 비교한다면 현재 국내 건설공사의 안전사고 사례는 점차 줄어들고 있는 추세이지만, 최근에 들어 건설공사가 보다 대형화, 복잡화되면서 사고의 규모는 더욱 더 커지고 있는 실정이다. 또한 실재 사고 손실액 역시 과거에 비하여 증가하고 있으며, 재해의 규모 또한 사망 등으로 번지는 대 재해로 변화하고 있다. 이러한 이유로 보다 확실한 안전관리가 필요한 상황이다. 본 저자는 이번 논문을 통하여 보다 효과적인 안전관리 프로그램을 제안하고자 한다. 이 프로그램은 시각화기술(Virtual Reality)을 이용한 안전관리 방법으로써 안전에 관한 속성 및 Entity 안전 라이브러리 등이 적용되었으며, 최종적으로는 과거의 지식 중심의 사후대처에서 벗어나 시각화를 통한 지속적인 관리 및 예방을 목적으로 하고 있다.

For the construction safety manager, it is expected that job stress is significantly high due to lack of expertise about new technology, new construction methods, and enlargement of scale as well as due to work intensity and unstable work hours. It is probable that such an increase in job stress not only has bad effects on individual, but also the bad effects spread to construction industry at large, resulting in rise in accident rate, increase in direct and indirect loss cost, and loss of reputation. In this context, methods for controlling construction safety manager's job stress are needed at the levels of both government and company. Therefore, this study investigated and analyzed the effects of construction safety manager's job stress on job satisfaction and job commitment, and proposed methods for relieving job stress. In addition, this study was suggested policies for higher job satisfaction and job commitment at the levels of the government and companies.

Recent government policies are increasing interest in zero-energy housing, a building that minimizes energy consumption (90% reduction). As the importance of building passive performance is emphasized, the role of insulation is increasing as a way to reduce indoor heat loss in order to minimize the use of cooling and heating energy. There are two main types of insulation. Organic insulation is widely used for various construction structures such as construction and industrial due to some merits such as the convenience of construction and construction cost. However, it has been pointed out as a main cause every time a fire accident occurs, Jecheon Sports Center', the fire damage of buildings caused by the use of organic insulation materials is expanding to social problems, so it is urgent to research on nonflammable inorganic insulation materials.

When an accident is happen due to using a bad Wire Compressor, some public resentments are caused and It cause lawsuit for we. In case, we will undergo a colossal financial loss. in addition to, Guide to improve quality of operation by using the number of times of pressing and pressing pressure with cooperative private enterprise. And because of needs for Thermal, Electrical and Chemical factor analysis of connection point of sleeve, expect to try improving problems of wire presser whole our company. We expect that reduce fault and save cost by this process. Consequently, we will prevent power losing and black out due to line faults by expulsion of inferiority equipment and prevent heating and line fault. This is possible using Alarming and Auto Locking Wire Compressor that is improve on this study.

The purpose of this study is to look at the case of the German compensation system for farmers' accidents and to build a basic scheme in our country's compensation system for farmers' accidents. When you view examples of Germany, the social insurance scheme for farmers accidents in korea should be design as an independent institution from the existing industrial accident insurance, and it comes to relationships with other social insurance system, preferably with complementary personalities. A general rule of the compensation system applies to all farmers in principle but the coverage limits part-time farmers. Financial burden consists of the mix of insurance premium and state aid. The type and level of benefits is similar to the current industrial accident insurance, which give priority to places on economic security for keeping farmworks, such as cost for using temporary farmers, rather than income loss. In terms of financial system, pay-as-you-go system would be better because of immediate payment with the introduction of the compensation system. The compensation system might be managed and administrated by the existing nationwide organization. Of course, for operating of system review and further research on the technical details such as premium issues and funding problems of government support, the exact classification of the target coverage, premiums based on estimated income for the farmers' estimation, the exact statistical data on the accumulation of agricultural disaster is needed.
