In this study, we had investigated several input factors and output factors, to maintain safety management, of domestic shipping companies, and then had analyzed the efficiency of performance of performance about each shipping companies' safety management system from 1998 year to 2004 year using DEA method As the result of analysis, the annual mean efficiency of total companies tended downward every year. Analysis was that the cause was increase of the cost of repairing ship, the cost of ship's stores and idle day of ship.

The purpose of this study is to design a proper evaluation method for analysing the safety management efficiency of coastal ship companies, and to verify these evaluation standards by applying them to a representative company. For this purpose, 5 evaluation items and 14 specific sub-evaluation elements have been determined after collecting practical opinions from a group of expert, which consisted of safety managers in passenger ship companies, public servants as a ship inspector, passenger ship operations managers, etc. Next, the safety management levels of 44 coastal passenger ship companies were evaluated using these standards. Finally, the validity of the proposed evaluation method was verified through comparison analysis between the evaluation results and the ratio of major marine accidents. It was determined that companies with low evaluation levels were saw more major marine accidents than other coastal passenger ship companies, spurring greater interest in safety management. In conclusion, evaluation standards allow coastal passenger ship companies to voluntarily assess their safety management level were established. The result can also be applied to analyse the operation efficiency of coastal passenger ship companies.

기술지도제도는 전문기술인력을 활용하여 재해율이 높은 중ㆍ소규모 현장의 건설재해를 효율적으로 관리하기 위해 정부가 간접적인 안전관리 전문제도로 도입하였다. 하지만 IMF 이후 급격히 변화된 건설현장 안전관리 체계와 재해율 증가, 지도기관 업체의 난립과 부실한 지도업무수행 등으로 기술지도제도의 실효성에 많은 문제점이 발생하고 있다. 따라서 본 연구에서는 기술지도제도의 운영 실태와 관계 법령, 설문조사 자료를 분석하여 문제점을 도출한 후 제도 운영상의 개선 방안, 지도기관의 전문성 강화 방안, 자율적인 안전관리 유도 방안으로 구분한 내실화 방안을 제시함으로써 효율적인 재해예방대책으로서 기술지도제도의 신뢰성을 제고시키는데 그 목적이 있다.

Safety management has been one of the most critical issues in the construction industry for a long time. Despite continuous efforts, it still shows a higher accident rate than other sectors. To reduce the accident rate, a lot of studies have been performed, mostly focused on contractors or construction phase. Although the initial stage of the construction project has the most significant impact on construction safety and decision-makers at the initial stage play an important role, the safety management system throughout the project entire life-cycle is still insufficient. In addition, although a great deal of information is generated in the construction project and the value is increasing, while it shows an inefficient aspect. This is believed to be due to insufficient information exchange and a lack of standards. In this context, this study aims to analyze the efficiency of information handover in construction safety. For this purpose, a safety management framework for systematically and efficiently managing and utilizing for construction safety information is referred to as 'safety business functions', 'project life-cycle', and 'industrial hierarchy'. The 'safety business functions' are classified into three levels. And then, in order to analyze the efficiency of safety information handover, 'importance of safety business function' and 'efficiency of safety information handover' were evaluated by interviewing with experts. This study can be used as reference data for implementing systematical and efficient safety management, and can also increase construction safety competency.

The result of analysis shows that the annual mean efficiency index of total companies tended downward every year. Analysis was that the cause was increase of the cost of repairing ship, the cost of ship's stores and idle day of ship while the number of marine accidents and sanctions of PSC, ship's insurances and P&I insurances was decreased.

Unsafe working environments slow down working speed in that it takes a lot of time to respond in case of an accident, greatly reducing the productivity of construction work. Therefore, proper safety management that does not impede the productivity of construction works is a very important factor for successful construction project. However especially in mega project, the mutual effects of safety management and productivity are complex. Therefore, this study establishes a causal model between safety management and productivity influencing factors based on effectiveness metrics, and analyzes the effect of increased site congestion due to excessive personnel input, irregular safety measures and inefficient change of work schedules. The result of this study, is expected to contribute to enhancing the competitiveness of the construction industry as the basis for establishing a safety management plan that can secure appropriate productivity.

한국원자력연구소에서 발생되는 방사성폐기물은 다양한 형태, 다양한 핵종으로 구성되며 소량씩 불규칙한 시기에 발생하는 특성을 갖는다. 이러한 폐기물의 효율적인 관리와 처리를 위하여 체계적인 이력관리와 신속한 통계를 도출할 수 있는 데이터베이스 시스템 구축이 선행과제로 대두되었다. 이에 방사성폐기물 통합관리 시스템(Radioactive Waste Management Integration System ; RAWMIS)을 구축하였으며, 이 시스템은 방사성폐기물의 발생부터 수집, 이동, 처리, 저장 등 처분까지의 이력을 관리하고, 서류간소화 및 인적자원 절약 등의 관리효율성을 제고하여 구현되었다. 또한, 한국원자력안전기술원에서 추진하는 국가적 방사성폐기물 통합 안전관리 체계(Waste Comprehensive Information Database : WACID)와 연계를 할 수 있도록 연구개발의 착수 단계에서부터 공동으로 진행하였다. 본 논문에서는 구축된 시스템의 구현사항과 실제 방사성폐기물 관리에 활용하는 사항을 제시한다. 본 연구를 통하여 구축된 시스템은 방사성폐기물 발생기관의 관리와 처리에 있어서 투명성과 효율을 증가시키고, 정확하고 신속한 정보를 도출할 수 있으며, 방사성폐기물의 관리와 처리공정의 데이터를 확보하여 방사성폐기물 처리 분야 연구의 토대를 제공할 수 있다.

Through the increment of requirement for group oriented communication services, on the open network, the multicast infrastructure has become a widely discussed researching topic. However the research of the security properties that safety, efficiency and scaleability in a multicast structure, has not been enough. In this study, we discuss conventional multicast key management structures and propose a scalable secure multicast key management structure based on PKI(Public Key Infrastructure), IPSec, domain subgroup and structural two mode scheme. Also we certify to the usability of new proposed scheme from comparing it with conventional schemes in the part of safety, efficiency and scaleability.

최근 인터넷의 급속한 발전은 다양한 서비스를 창출하였으며, 모든 사용자에게 제공되던 브로드 캐스팅적 서비스에서 일부 사용자만을 위한 여러 가지 새로운 서비스로 변화하고 있다. 새로운 형태의 서비스의 경우 그룹 형태의 사용자들의 안전성을 보장하면서 효율적인 관리 구조에 대한 연구보다는 그룹의 서비스의 효율성에 목적을 두어 사용자의 프라이버시 침해에 대한 논란을 야기 시키고 있다. 따라서 본 논문에서는 기존의 멀티캐스팅 그룹 설정에 기반한 LBT 트리에 그룹 네트워크가 설정 될 경우 그룹원들간의 안전성을 제공하면서 관리의 효율성과 확장성 갖는 관리 방식을 제안하고자 한다. 제안 방식은 LBT트리의 특징을 그대로 유지하면서 기존 방식에서의 안전성에 대한 취약점을 보완하여 보다 안전하고 효율적인 방식을 제안하였다.

This paper presents integrated control and safety management system for a LNG storage tank. This system is for collecting and analyzing the temperature, pressure, and vibration signals in which are used to control and guarantee the system safety and leakage control from the inner gas tank. Based on the investigations of LNG tank related failures and accidents, we strongly recommend the modification and new development of current safety related measuring and control systems because the LNG tank is constructed bigger and bigger in recent years for the efficiency and safety increments. Thus, this paper presents newly developed integrated control and safety management system for a large LNG storage tank. This system provides the enhanced measuring and control systems, and new displacement based safety system, which may detect and control the deformation properties of tank structures. In addition, we recommend that the new integrated control and safety management system should be coupled by process integrated innovation system (PIIS) for an increased safety, efficiency, and productivity of LNG tanks.
