The shipboard working environment of coastal ship is very inferior too the ground working environment and it causes the avoidance of shipboard working and the aging of crew. Especially the air pollution and electromagnetic wave in ships causes an occupational disease. hence to reduce the shipboard working fatigue is necessary by the security of the comfortable shipboard working environment and residence environment. in this paper, first we evaluate the shipboard working environment by using the measurement results of the shipboard air polluting and electromagnetic wave in the sea. And we propose the reduction measures of shipboard working fatigue based on the evaluation results of the shipboard working environment.

The shipboard working environment of coastal ship s very inferior to the ground working environment and it causes the avoidance of shipboard working and the aging of crew. Especially the noise in ships causes an occupational disease such as hardness of hearing. Hence to reduce the shipboard working fatigue is necessary by the security of the comfortable shipboard working environment and residence environment. in the sea. And we propose the shipboard working environment by using the measurement results of the shipboard noise and vibration in the sea. And we propose the reduction measures of shipboard working fatigue based on the evaluation results of the shipboard working environment.

The shipboard working environment of coastal patrol ship is very inferior to the ground working environment and it cause the avoidance of shipboard working and the aging of crew. Especially the noise in ship cause on occupational shipboard working hardness of hearing. Hence to reduce the shipboard working fatigue is necessary by the security of the comfortable shipboard working environment and residence environment. in this paper, firstly we evaluate the shipboard working by suing the measurement results of the evaluation results of the shipboard working environment.

현재 우리나라는 보유 또는 지배선박이 약 1,000척, 3천만G/T로 노르웨이에 이어 세계 6위의 해운강국으로 성장하였다. 그리고 수많은 사관과 부원들이 다양한 선박에 승선하고 있으며 해운산업이 성장할수록 더 많은 선원들이 선박에 근무할 것으로 예상된다. 그러나 IMO와 ILO 등에서는 선원들의 선박근무환경 및 휴식 등에 관해서 최소한만을 규정하고 있고, 이로 인하여 선원들이 높은 노동 강도에 시달리게 되고 피로와 스트레스가 누적되어 해양사고의 한 원인이 되고 있는 실정이다. 이 연구에서는 각 선박의 고유 특성과 운항환경 등으로 고려한 선박의 근무강도를 평가할 수 있는 요소와 지수를 개발하기 위하여 선박에 장기간 승선한 경험이 있는 응답자로 하여금 각 평가요소에 대하여 주관적으로 인지하는 선박의 근무강도를 평가하도록 하였다. 이 평가요소와 지수를 기반으로 선원들을 각 선원의 특성과 여건에 맞는 선박에 배정함으로서 선원들의 피로와 스트레스를 경감시켜 해양사고의 예방에 기여할 수 있을 것으로 예상된다.

최근 항공 산업 발전으로 여행객들의 수가 증가하고 있으며, 호텔 이용객 수도 더불어 증가하는 추세이다. 호텔 이용객의 증가로 시설 이용 시 서비스 지연과 혼잡 그리고 서비스 품질 저하 등이 발생하게 되면서 호텔 이용객들의 시설 이용 만족도가 하락하게 되고 또한 호텔 근무 직원들의 업무 피로도가 높아지고 누적되면서 직업 만족도가 떨어지는 연쇄적인 문제점들이 발생하고 있다. 본 연구는 호텔에 방문하는 이용객들에게 캐리어 운반과 객실 안내 및 호출 서비스 등 각종 서비스 업무를 직원 대신 수행하게 되면서 현 문제점들을 어느 정도 경감시키고 이에 따라 고객 만족도 및 호텔 직원들의 업무 만족도를 증가시킬 수 있을 것으로 사료된다.

This research started with the objective to clarify how policemen are affected by promotion by test among promotion system of police which is one of the very important factors deciding the efficiency of organization through morale of policemen and which is mentioned as a factor that raises morale of policeman. The job of police is the ground of life for policemen and the place of opportunity where they can find and develop the ego. Though it is difficult to perfectly realize diverse values and desires of individuals in the organizational society which is ruled by plural values, the organization is still responsible for grasping the desire and value of individual for organization and satisfying them to the minimal level. Nobody is free from stress in the past, present and future. That is, stress can be seen as a phenomenon that inevitably occurs in any occupation and environment. The stress factor of policeman in the organization that has been discussed all the time is the deficient opportunities of promotion. Thus, it is most important to manage the stress of members in the organization so as to efficiently operate police organization. If the factor of stress perceived by the members can be grasped and diminished, the efficiency of business will be increased. The objective of this research is to reduce the stress of policemen suffering in the test promotion system by analyzing the recognition of members, to find the method reducing stress by performing empirical research and to prepare alternatives in policy in the aspect of human resources in police and management of organization.

According to the related reports, about 60 percents of ship collisions have resulted from operating mistake caused by human factor. Specially, the report said that negligence of observation caused 66.8 percents of the accidents due to a human factor. Hence automatic detection and tracking of an object from an IR images are crucial for safety navigation because it can relieve officer's burden and remedies imperfections of human visual system. In this paper, we present a method to detect an object such as ship, rock and buoy from a sea IR image. Most edge directions of the sea image are horizontal and most vertical edges come out from the object areas. The presented method uses them as a characteristic for the object detection. Vertical edges are extracted from the input image and isolated edges are eliminated. Then morphological closing operation is performed on the vertical edges. This caused vertical edges that actually compose an object be connected and become an object candidate region. Next, reference object regions are extracted using horizontal edges, which appear on the boundaries between surface of the sea and the objects. Finally, object regions are acquired by sequentially integrating reference region and object candidate regions.
