This study is a study to develop a model to measure the economic performance when introducing industrial safety design, which is emerging as a necessity for industrial accident prevention measures due to the increase in the industrial site nursing accident rate and the enforcement of the Serious Accident Punishment Act. To this end, studies on the concept of industrial safety management and industrial safety design and economic performance measurement in the field of industrial safety were conducted in terms of theoretical background. Based on the theoretical background, opinions on drafts of related indicators were collected through user opinion surveys, and focus group interviews and Delphi techniques were conducted with experts, and research was conducted to advance the model. In order to secure objectivity, the causal relationship between the introduction of industrial safety design, cost reduction effect, and sales increase effect was tested through regression analysis. After going through these steps, two models of economic performance measurement of industrial safety design were finally developed: a model based on the first-stage disaster loss cost reduction effect and a second-stage sales increase effect. In order to be applied to actual industrial sites, it should be able to be presented as a standard for the degree of service level agreement of industrial safety design beyond a simple checklist.

황천 운항 중인 선박은 파도에 의한 과도한 운동과 그로 인한 슬래밍, 프로펠러노출, 갑판침수와 같은 현상으로 구조, 화물, 인명에 위험을 초래할 수 있다. 이 때문에 황천 시 선박은 안전 운항을 위하여 속도와 코스를 신중히 결정할 필요가 있다. 선박 운동 모니터링 시스템은 해상환경이 선박에 미치는 다양한 위험 상황을 사전에 예측하고 피할 수 있도록 의사 결정을 지원하며, 현재 선박의 운동상태와 구조적 안정성을 지속적으로 모니터링 함으로써 선박, 선원, 화물의 안전을 지원할 수 있도록 개발되었다. 본 시스템은 주파수 영역에서 New strip 방법에 기초하여 운동 응답과 수직 굽힘 모멘트를 계산하며, 슬래밍, 프로펠러노출, 갑판침수를 예측한다. 또한 선박 운동과 선체구조응력을 실시간으로 모니터링하여 과도한 선체운동이나 선체구조피로 등의 위험 상황을 표시하고 선원의 작업성과 승선감의 지표인 MII (Motion induced interruption), MSI (Motion sickness incidence)를 제공한다.

Emerging automated driving environments will lead to a mixed traffic flow depending on the interaction between automated vehicles (AVs) and manually driven vehicles (MVs) because the market penetration rate (MPR) of AVs will gradually increase over time. Understanding the characteristics of mixed traffic conditions, and developing a method to control both AV and MV maneuverings smoothly is a backbone of the traffic management in the era of automated driving. To facilitate smooth vehicle interactions, the maneuvering of AVs should be properly determined by various traffic and road conditions, which motivates this study. This study investigated whether the aggressiveness of AV maneuvering, defined as automated driving aggressiveness (ADA), affect the performance of mixed traffic flow. VISSIM microscopic simulation experiments were conducted to derive proper ADAs for satisfying both the traffic safety and the operational efficiency. Traffic conflict rates and average travel speeds were used as indicators for the performance of safety and operations. While conducting simulations, level of service(LOS) and market penetration rate(MPR) of AVs were also taken into considerations. Results implies that an effective guideline to manage the ADA under various traffic and road conditions needs to be developed from the perspective of traffic operations to optimize traffic performances.

상수관망은 충분한 양질의 수돗물을 공급하기 위한 사회기반 시설물이다. 상수관로의 노후화, 누수 등은 수도 사고 발생의 가능성을 증가시키고, 수돗물 안전성에 대한 신뢰도를 감소시킨다. 수돗물 공급 전 과정을 인공지능(AI), 정보통신기술(ICT)과 결합한 지능형 상수도관 예측 및 관리 시스템을 구축하여, 상수도 수질 사고를 조기에 감지하고 사전에 취약지점을 예측할 필요가 있다. 이를 위해서는 상수관로의 위험도를 평가하기 위한 체계적인 데이터와 기준이 필요하다. 본 연구에서는 상수관로의 위험도 예측모델을 개발하기 위해 상수관로 위험도와 관련된 평가 인자를 선정하고 분류하였으며, 각 인자의 명확한 기준을 제시하였다. 국내·외 상수도 위험도 평가 항목에 대한 자료를 비교 및 분석하였고, 전문가 자문을 통해 인자를 정립하여 상수관로 위험도 평가 지표를 개발하였다. 개발된 평가 지표의 현장 적용성과 실효성 검증을 위해 정량적인 데이터 확보가 가능하고 상태를 평가할 수 있는 대상 지역을 선정하였다. 문헌 자료의 평가항목들과 전문가 의견을 바탕으로 상수관로 위험도 평가 인자를 31개의 직접 인자와 5개의 간접 인자로 구분하였고, 인자별 평가 기준을 제시하였다. 직접 인자는 노후화 정도를 파악할 수 있는 노후도 평가 항목, 지역 특성을 반영한 토양 부식성 항목, 실시간으로 측정하여 결과를 제공하는 실시간 계측 항목, 직접적인 수질 결과를 제공하는 정수장 수질 항목, 상수관로의 건전성을 평가하는 자산관리 항목으로 분류하였다. 추후, 위험도 평가 운용을 위한 알고리즘을 개발하면 상수도 사고 위험에 대한 예방 및 대응 전략을 수립할 수 있을 것으로 기대된다.

The purpose of this paper is to assess the financial strength of general insurers by using A.M. Best's rating technique focusing on quantitative standards. A quantitative evaluation of fifteen larger general insurers' financial strength and operating performance relative to the Best's top group is carried out. The quantitative evaluation is done in 5 key areas; growth, efficiency, profitability, safety and liquidity. The results show that there is a big gap between domestic large insurers and American insures in all areas except stable growth of operations. Therefore, domestic insurers have to strive to strengthen financial soundness through profitability and should increase the capacity to retain more commercial business and reinsurance in order to become global players.

The oversea construction contract amount has sharply increased since 2003. The contractor's capability for EPC and project management is a key factor for a successful industrial construction project. Construction performance measurement and evaluation is needed to improve contractor's project management capability. Therefore, this paper proposes the construction performance benchmarking program for oversea industrial projects. Performance metrics consists of project cost, schedule, quality, and safety. Data from 10 oversea industrial projects were collected and analyzed. Also, this paper describes the process for development of the benchmarking program and lessons learned from industry are summarized. Finally, this paper recommends how sustainable benchmarking program should be established and implemented.

The size of state in Korea is like Israel, this country's venture capital is ruled by government. This venture capital's character is below: the concentration on research of venturer affect positively at qualify of products, This paper lies with venture capital's risk character & performance. The results show that Korean venture capitals have lager unsystematic risk than systematic risk, which implies they specialize in specific business and/or regional areas instead of diversification. The Sharpe measure reveals that the performances of Korean venture capitals are very low relative to even the market portfolio(Kospi) and Kosdaq.

The CEOs of global companies have been realized the imagination and creativity that can be obtained from the corporate culture is the crucial competitive power for sustainable growth. Thus, most domestic companies take an increasing interest in how to make creativity efficiently. This paper, however, argues that the proper application of performance indicators can engender creativity and innovation in organizations without costly investing on creativity. Assuming that creativity is actually dominated by the emotion of human resources rather than the rationality, this paper suggests the performance indicators developed based on the viewpoint of the characteristics of human needs and the relationship between the human needs and the attribute of works. The performance system which consists of activity, sociality and creativity is presented and the performance indicators for each category are also suggested to improve the spontaneity and creativity of human resources.

오늘날 많은 제조업체 또는 물류업체는 물류의 효과적 수행을 위해 물류센터를 운영하고 있으며, 물류센터의 효과적 이용을 통한 물류문제 해결은 기업운영에 있어서 주요 해결과제 가운데 하나로 자리잡게 되었다. 이러한 물류센터를 운영하고 관리함에 있어서 물류센터의 전략적 의사결정과 투자계획의 수립을 위해 물류센터의 수행도 측정을 통한 정량적인 평가가 절대적으로 필요하게 되었다. 그러나 현재 기업물류활동을 평가하기 위한 여러가지 물류활동 측정지표들이 제시되고 있으나 물류센터들의 수행도 측정을 위해 체계적으로 정의화되고, 표준적으로 사용되는 유력한 정량적 평가방법이 아직 제시되어 있지 않다. 본 연구에서는 물류센터의 특성을 Cost(비용), Operation(설비운영). Quality(성과), Speed(속도), Flexibility(유연성), Safety(안전성)등 모두 여섯 가지로 구분하여 각각의 특성을 통해 물류센터를 정량적으로 평가한다. 이중 Safety(안전성)를 기본으로 삼고 나머지 주요인자들의 정량적 평가치 들을 통해 물류센터의 종합적인 수행도 평가 모델을 제시하였다. 물류센터의 운영평가는 궁극적인 공급체인관리망(SCM: Supply Chain Management)의 완성과 기업의 업무효율에 이바지하는 것이다.
