Objective: This study aims to introduce the bridge resource management (BRM) training courses implemented in Korea and to analyze their effectiveness in several views. Background: BRM training will be a mandatory course for crew members of ships from 2017. At this stage, it is needed to check if the BRM training courses implemented until now was effective to the Korean maritime safety and to investigate if there are more effective training methods. Method: The effectiveness of BRM training intervention in Korea was compared with that of the other countries, using Kirkpatrick's (1976) training evaluation framework. Kim (2012)'s data on the BRM training effectiveness were re-analyzed in order to check if the effects of BRM training are dependent on the bridge work experience. Results: Many BRM training courses has been opened in Korea. However, the methods to assess BRM training effects used in Korea focused on the survey of subjective satisfaction level, not investigating trainees' attitude and behavior change. On the other hand, the effectiveness of BRM training was higher to the bridge officers with long work experience than with shorter work experience. Conclusion: The contents of BRM training should be changed to effectively apply to the context of the real-world exercise and be differentiated depending on the work experience. Research on the methods to measure the BRM training effectiveness is also more required. Application: The results of this study will aid to develop the BRM training courses for bridge officers of ships in the BRM training institutions.

Advanced Life Support Systems (ALSS) are being studied to support human life during long-duration space missions. ALSS can be categorized into four subsystems: Crew, Biomass Production, Food Processing and Nutrition, Waste Processing and Resource Recovery. The System Studies and Modeling (SSM) team of New Jersey-NASA Specialized Center of Research and Training (NJ-NSCORT) has facilitated and conducted analyses of ALSS to address systems level issues. The underlying concept of the SSM work is to enable the effective utilization of information to aid in planning, analysis, design, management, and operation of ALSS and their components. Analytical tools and computer models for ALSS analyses have been developed and implemented for value-added information processing. The results of analyses have been delivered through the Internet for effective communication within the advanced life support (ALS) community. Several modeling paradigms have been explored by developing tools for use in systems analysis. They include object-oriented approach for top-level models, procedural approach for process-level models, and application of commercially available modeling tools such as MATLAB$\^$(R)//Simulink$\^$(R)/. Every paradigm has its particular applicability for the purpose of modeling work. An overview is presented of the systems studies and modeling work conducted by the NJ-NSCORT SSM team in its efforts to provide systems analysis capabilities to the ALS community. The experience gained and the analytical tools developed from this work can be extended to solving problems encountered in general agriculture.

This study intends to present a direction for the better reforming of fishers'onboard living conditions and proposals for preparing for ratification of the Work in Fishing Convention by means of making a comparison between standards on recent national fishing vessel accommodation facilities and standards on the Work in Fishing Convention and Its Recommendation, 2007, ILO. For the most part of standards on national fishing vessel accommodation facilities are somewhat insufficient to satisfy the provisions in Annex III of the Convention. Considering by items on fishing vessel accommodation facilities, the standards on insect protector, noise and vibration, heating and air conditioning, lighting, persons per sleeping room, recreational facility are not provided in national law. Headroom, separation of accommodation, sleeping room floor area, mattress size, mess room, galley and food storage are partially sufficient for the Convention. In case of sanitary facilities, national standards are not sufficient for the Convention. The other side, facilities related safety of ship and crew such as emergency escape etc., are fully sufficient for the Convention. These insufficiencies caused by different types of fishing vessel depend on originality of fishing method and practices. In the comparison between equivalent tonnage about vessel's length on convention and calculated tonnage of national existing fishing vessel, the difference are 226tons about length 24m and 501tons about length 45m. For that reason, headroom, persons per sleeping room, cabin of sicker and injured, sanitary facilities may decide to use gross tonnage in place of length (L) and the alleviating measure basis of convention. But in case of standards on sanitary facilities which are unsufficient for the Convention, specially in coastal fishing vessel length basis should be adopted with alleviating basis for less than length 24m.

1970년대부터 고도의 산업발전을 이루기 시작한 국내 건설현장에서 저렴한 공사비용 및 간편한 시공성 등을 장점으로 샌드위치패널을 활용한 건축물이 급격하게 증가하는 실정이다. 하지만 샌드위치 패널의 시공을 담당하는 기업들은 대형 건설업체보다 중소건설업체인 관계로 생산성 향상을 위한 연구가 부족한 상황이다. 본 연구는 샌드위치패널공사 현장조사를 하여 작업조별 작업싸이클을 분석하고 Webcyclone을 이용한 모델링을 하였으며, 각 작업조별 생산성 및 공사금액을 분석하였다. 또한 생산성 영향요인중 하나인 패널의 가공장소에 따른 생산성 및 공사금액의 변동을 민감도 분석하여 각 작업조별 최적화된 생산성 및 공사금액을 분석하였다. 분석결과 공장가공 작업조가 현장가공 작업조에 비하여 약 30% 정도의 생산성이 향상됨으로 조사되었고, 공사비용 분석 결과 약 15% 정도의 공사비용이 증가됨으로 조사되었다. 또한 개구부 요율에 따른 민감도 분석에 의하여 약 20% 정도의 개구부를 공장에서 가공을 하였을 때 공사금액 최적화가 이루어짐을 보여준다.

항해사의 업무수행도 감소는 해양사고 발생의 주요 원인 중의 하나로 자주 언급되고 있다. 인터뷰와 항해 기록 분석을 통한 선원의 작업시간 분석에 대한 연구는 일부를 수행되었으나, 작업부하, 작업교대, 스트레스, 수면 등이 선원의 인지능력에 미치는 영향을 분석한 사례 매우 한정적이다. 항공, 철도와 같은 다른 운송 산업에서는 승무원의 근무 패턴을 관리하기 위한 피로관리 도구를 개발하고 있고 있는데, 이러한 도구들은 선원, 항해사 및 육상관리자의 효율적인 근무일정을 계획하는데 도움을 줄 수 있다. 따라서 본 연구에서는 항해사의 인지능력을 평가하기 위해, 해상 충돌상황에서의 종합적 대응능력을 평가할 수 있는 소프트웨어 프로그램을 개발하였다. 항해 전문가를 대상으로 한 실험을 통하여, 평가기준을 개발하였으며, 실습 항해사를 대상으로 하여 시스템에 대한 검증이 이루어졌다. 본 시스템은 선박운항 시 충돌사고를 회피하기 위한 항해사의 인지능력을 평가할 수 있으므로, 당직 전 혹은 승선 전에 짧은 시간 동안의 평가를 통하여 항해사의 전반적 인지능력을 평가하고, 이 결과를 항해사에게 경고메시지 형태로 전달할 수 있다.

초고층 건축공사에서 리프트카를 이용한 자재 양중 관리는 핵심적인 관리분야 중 하나이다. 기존 연구들은 양중계획의 기본 단위인 양중 사이클타임이나 리프트카의 운행효율은 기존 사례를 참고하여 적용하거나 관리목표로 설정하고 개략적으로 산정하는 한계가 있었다. 따라서 본 연구에서는 양중 사이클타임을 단축하고 가동율을 향상시키기 위하여 자재 양중작업 프로세스를 최적화하는 방법론 제안을 목표로 하였다. CYCLONE 모델을 변형하여 작업시간과 작업위치를 반영할 수 있도록 개선하고, 세부 작업을 조정하여 프로세스를 최적화 하는 방법론을 제안하였다. 이 방법론에 따라 양중작업 프로세스를 개선하고 민감도 분석과 현장 적용성 평가를 실시하였으며 초고층 현장에 적용하였다. 기존 작업 프로세스와 개선된 작업 프로세스를 양중 높이별로 시뮬레이션하고 이를 현장 적용 결과 데이터와 비교하여 양중작업 시간 단축과 가동율 향상 정도를 비교 분석하여 최적화 방법론의 효용성을 검증하였다.
