  • 산업안전보건관리비는 산업 현장에서 발생하는 인적 안전사고를 사전에 방지하기 위한 목적으로 1988년에 시행되었다. 그러나 다섯 개의 공사종류와 세 개의 공사금액을 기준으로 한 산업안전보건관리비의 계상기준은 다양한 건축현장의 특성을 반영하지 못하고 있다. 이를 연구하기 위해, 본 연구는 국내건설업체 현장의 건설업 산업안전보건관리비의 사용률과 사용세부항목을 분석하였다. 그 결과, 상당수의 현장에서 산업안전보건관리비를 초과 사용한 사실과 그 원인을 밝혀낼 수 있었다. 이를 토대로 본 연구에서는 건설업 산업안전보건관리비의 계상기준 개선의 필요성과 방향성을 제시하고자 하였다.

  • 본 연구는 연안여객선사의 안전관리 운영 효율성을 분석하기 위한 기초연구로 적절한 안전경영지표 평가항목을 설계하고 연안여객선사를 대상으로 평가항목의 유효성을 검증하는데 목적이 있다. 이를 위해 먼저 연안여객운송사업자의 안전관리책임자, 공무원(선박검사관), 여객선 운항관리자 등으로 구성된 전문가 그룹을 통해 연안여객선사의 자발적 안전관리 활동을 평가하기 위한 5개의 평가항목과 14개의 세부 평가요인을 선정하고 사전검증 및 테스트를 통해 객관성을 제고하였다. 이 안전경영지표 평가항목을 이용하여 44개 연안여객선사에 대한 자발적 안전관리 수준을 평가하였다. 그리고 평가항목의 유효성을 검증하기 위하여 안전경영지표 평가항목 결과와 중대해양사고 비율을 비교분석하여 평가항목의 타당성을 확인하였다. 이를 통해 자발적 안전경영 수준이 높은 업체일수록 중대해양사고가 발생하지 않고 자발적 안전관리에 무관심하거나 소홀한 업체는 상대적으로 높은 중대해양사고가 발생하고 있는 것을 알 수 있었다. 이처럼 안전경영지표 평가항목 선정을 통해 연안여객선사의 안전관리 운영 효율성을 분석하는데 중요한 항목을 객관적인 관점에서 도출하였다. 따라서 향후 안전관리 효율성 분석을 위한 기초자료로 활용될 수 있을 것이다.

  • Electric motors and drives consume the largest amount of electricity more than 40% of global electricity consumption. In addition, motors, drives and its components are included in the global high-trade products and the main driving source for industrial equipment and house appliances. Thus, International standards and regulations for their safety and efficiency are internationally being discussed and created for the protection of its citizens and energy saving. So, understanding the international standards and the regulation of each country is essential to enhance overseas market and to develop product. In this paper, on the basis of this background, status and trends of international standards and regulations are introduced for safety and efficiency of motors and the drives. Safety and efficiency of the IEC (International Electrotechical Commission) standards are introduced in the emphasis. Also, regulations are studied about the differences and trends in each county.

  • According to a survey conducted recently, consumers are feeling the anxiety to food, it can be seen that the extent to which feels uneasy about pesticide residues among them in particular is high. Foods that are commercially available, is set (pesticide residue standards, acceptable daily intake daily (ADI), non-toxic amount) residual acceptable standards of pesticides so as not to give the damage to human health. However, in the case of consumers of general knowledge on Standards for pesticide residues is not sufficient, anxiety over food safety still exists. Therefore, in this study, as can be easily understood and accurate information to consumers a general basic knowledge on the safety of food is insufficient is related to food safety, was utilizing the graphic display of a one-dimensional you are trying to provide information providing method. As a result, in the display method is utilized to provide the information on food existing for, from the form of the information by utilizing the graphs and characters, using a graphical display showing the criteria for pesticide residues in one dimension it was found that the display shows how to readily appreciate the most accurate and safety standards regarding pesticide residues.

  • The bottom of dikes must be kept impermeable to control hazardous chemicals spilled from storage tanks. Currently, insufficient related chemical control laws lead to a possibility to spread through the bottom. Generally, due to the high cost of installation and periodical maintenance, many businesses prefer to install the bottom with general concrete. But, since the impermeability of concrete is dependent on the kind of materials and chemical reaction, all concrete cannot be considered as impermeable material. Thus, it is necessary to make the installation standards of the dike bottom clear in order to avoid the argument over the impermeability and prevent the chemical accident. This study has suggested the standards of impermeable concrete by conducting 7-day exposure test to crude oil with the pilot dikes. The results have showed that the standards have the better impermeable performance compared with the germany standard, which have been penetrated at the maximum penetration depth of 1.9 cm. This study is expected to contribute to both the risk reduction of penetrating into the bottom and the cost reduction of spending to make the bottom of dikes impermeable.

  • Infrared thermography uses infrared energy radiated from any objects above absolute zero temperature, and the range of its application has been constantly broadened. As one of the active test techniques detecting radiant energy generated when energy is applied to an object, ultrasound infrared thermography is a method of detecting defects through hot spots occurring at a defect area when 15~100 kHz of ultrasound is excited to an object. This technique is effective in detecting a wide range affected by ultrasound and vibration in real time. Especially, it is really effective when a defect area is minute. Therefore, this study conducted thermography through lock-in signal processing when an actual defect exists inside the austenite STS304 seamless pipe, which simulates thermal fatigue cracks in a nuclear power plant pipe. With ultrasound excited, this study could detect defects on the rear of a pipe by using an aluminium reflector. Besides, by regulating the angle of the aluminium reflector, this study could detect both front and rear defects as a single infrared thermography image.
