As the manufacturing systems adapt information technology, safety control and management systems are required to adapt information technology by changing the industrial environment. This paper is presented the methodology of designing the safety control and management system based on intranetwork environment to reduce breakdown time on facility and Increase efficience of safety training and education.

한국에서는 많은 산업재해로 인해 물질적 손실뿐만 아니라 국가 신뢰도에도 영향을 미치고 있어 선진국이 되기 위해서는 산업재해를 획기적으로 줄여야만 한다. 산업재해 예방을 위해서는 여러 방법 중 각 사업장의 안전관리를 담당하고 있는 산업안전관리자를 좀더 효율적으로 양성할 필요가 있다. 효율적인 안전관리자를 양성하기 위해서는 이들의 교육과목이 체계적으로 연구되어 각 과목들의 상대적 중요성의 분석이 필요하다. 본 논문에서는 이들 교과목의 상대적 중요도를 분석하였고 이의 타당성을 평가하였다. 안전관리자를 위한 상대적 중요도 분석은 AHP(Analytical Hierarchy Process)를 이용하였다. 분석결과 안전관리분야(W=0.355), 인간공학 및 시스템안전분야(W=0.242), 기계안전분야(W=0.13), 건설안전분야(W=0.12), 전기안전분야 (W=0.091), 화공안전분야(W=0.062)순으로 안전관리분야와 인간공학 및 시스템 안전분야의 상대적 중요성이 높게 평가되었다. 이러한 결과는 학교 교과목뿐만 아니라 산업안전공단이나 산업안전협회 등의 안전교육 계획수립 시에도 많은 도움이 될 것이다.

해마다 여름철에 동해안 해수욕장을 찾는 피서객이 늘어남에 따라 그와 비례하여 해수욕장 안전사고도 늘고 있는 것이 현실이지만 해수욕장의 안전관리 실태나 피서객의 안전의식은 과거와 크게 달라진 것이 없으므로 안전사고도 늘어날 수밖에 없는 현실이다. 이에 해수욕장 안전사고를 줄이기 위한 첫 단계로 피서객들이 어느 정도의 안전의식을 가지고 있는가와 과연 그들이 자신들이 방문한 해수욕장의 안전시설이나 관리 상태에 어느 정도 관심을 가지고 있는지 그리고 만족하는지를 조사하여 보았고 구체적으로 어느 부분에 문제가 있는 지를 개별면접을 통한 설문조사를 광범위하게 실시하여 본 논문을 작성하였다. 설문 기간은 1999년 7월 29일부터 8월 9일까지 2주일 동안 동해안의 주요 해수욕장인 속초해수욕장, 낙산해수욕장, 경포대해수욕장, 망상해수욕장의 4곳의 해수욕장에서 600여 개의 설문지를 토대로 여러 가지 질문들에 대한 SAS 통계 분석을 시도하였다. 우리나라 실정에 맞는 해수욕장 안전관리 가이드 라인을 설정할 수 있는 기초 연구로 삼기 위해 이 조사를 수행하였다. 차후 연구는 이를 기초로 하여 보다 광범위한 설문조사 및 실태조사를 실시하고 분석하고, 다른 나라의 해수욕장 안전 관리 실태와 비교 분석하여 우리나라의 현 상황을 진단한 후, 우리나라 실정에 맞는 해수욕장 안전관리 가이드 라인을 설정할 수 있을 것이다.

Most of chemical plant are using toxic and dangerous materials, inflammable and poisonous. There are many accidental dangers by escaping of fire, explosive and poisonous materials in case of high temperature and pressure. The accidents lead to taking employer's and local people's life and environmental contamination. Therefore, 27 small-medium chemical plant, which size is 30∼200 employees out of safety management agent in the area of A was selected in this study. The problems of safety management and several countermeasures at the chemical plants was indicated through the analyzed data. Prior to this analysis, top managers' concerns, equipment maintenance for the safety management are needed. For the future, calamity prevention countermeasures by industrial disaster analysis are needed and active safety management programs are investigated for the industrial disaster prevention and productivity enhancement at the chemical plant.

This paper presents the safety management model, which is appropriate for small-to-medium enterprises that rank the highest disaster rate. It is required for these companies to modify and improve the safety-related articles and it is performed to compare and analyze the industrial disasters and safety management systems between large enterprises and small-to-medium enterprises. The basic direction of change of industrial safety healthy system must be classified to the dual direction. For large enterprises, it is focused on not pre-regulations but post-regulations based on the self-control safety management system. But for small-to-medium enterprises, it is required to intensify the safety management system and the safety responsibility for owners or administrators. Specially, the responsibility for disaster must be more strengthened by the penalty and the insurance method, and then it must be performed not only the financial support of government but also middle and long-term technical support by private safety organizations.

IPQC system was introduced for the flight safety at the age of scientific safety management in the 1980s. In spite of performing this system, aircraft accidents caused by human factors, which were above 70% among all flight accident factors, have not been reduced. Accordingly, throughout this paper I analyzed the aircraft accident factors by means of a literature study and a pilot survey. Then, based on the notion of TQC(Total Quality Control), I hierarchically classified Individual Quality into Capacity Management, Safety Management, and General Management and did the low-ranked management factors as well. AHP (Analytic Hierarchy Process), one of the scientific management methods, was used for estimating the relative importance of Individual Quality Control factors and the heavy aircraft accident causes over the last 20 years were analyzed according to the flight ranks. Based on the comparative analysis of results derived above, an IPQC model as flight ranks is established. In short, according to this newly suggested model we can obtain the maximum flight safety with the preventive actions against aircraft accidents caused by human factors and by improving the operation effect under the reasonable pilot management.

This study is concerned with developing a heuristic algorithm for solving a class of ninlinear integer programs(NLIP). Exact algrithm for solving a NLIP either may not exist, or may take an unrealistically large amount of computing time. This study develops a new heuristic, the Excursion Algorithm(EA), for solving a class of NLIP's. It turns out that excursions over a bounded feasible and/or infeasible region is effective in alleviation the risks of being trapped at a lical optimum. The developed EA is applied to the redundancy optimization problems for improving the system safety, and is compared with other existing heuristic methods. We also include simulated annealing(SA) method in the comparision experiment due to ist populatrity for solving complex combinatorial problems. Computational results indicate that the proposed EA performs consistently better than the other in terms of solution quality, with moderate increase in computing time. Therefore, the proposed EA is believed to be an attractive alternative to other heuristic methods.

Research activities and discussions on specialized areas reflecting the specificity of landscape construction are necessary. Therefore, this study was conducted with the purpose of presenting basic data for efficient field management by deriving items necessary for safety management in landscape construction fields through experts' opinions. A survey was conducted using Delphi analysis to derive "management items" and "safety management items according to landscape type" for landscape construction field safety for a total of 15 landscape construction specialists. The survey results showed that four top items were derived from the "management items" for the safety of landscape construction fields; they include: "safety and health management organization and education," "industrial safety and health management expenses," "payment of personal protection," and "establishment of safety measures." In addition, two to five items for each higher item appeared and resulted in a total of 13 lower items. Personnel, organization, budget, etc. for safety management are always required in the field, and the monitoring part of whether these elements are working was also taken up as a management item. In the "Management items according to each landscape construction" a total of eight landscape type were distinguished, they include: ‘Reinforced concrete work’, ‘Masonry work’, ‘Plaster's work’, ‘Waterproof work’, ‘Stone masonry work’, ‘Pavement work’, ‘Facilities work’, and ‘Planting work’. Furthermore, two to seven sub-items for each construction type were derived, and a total of 35 management items were presented.

일정 규모 이상의 사장교와 현수교에는 자유장, 주탑, 보강거더에 지진가속도계가 부착되어 있다. 이 연구에서는 부착된 센서를 활용하여 지진발생 시에 긴급하게 지진안전성을 평가하는 방법을 제안하였다. 표준화된 시스템으로 긴급한 평가가 이루어지므로 센서 단위의 평가가 효과적이며, 경주, 포항지진에 대한 특수교량의 데이터 분석을 통하여 평가 방안을 도출하였다. 자유장, 교각기초, 앵커리지와 같이 지반 또는 지반과 인접한 위치에 설치된 가속도계는 최대가속도로 평가를 수행하고 주탑상부, 보강거더 등 구조물에 부착된 가속도계는 가속도의 변환을 통한 변위비교로 평가를 수행하는 것을 제안하였다.
