선박근무자의 피로는 해양사고의 잠재적 요인으로 혹은 인적과실에 기여하는 한 요인 정도로만으로 여겨졌으나, 최근 이와 관련한 연구에 의하면 선박근무자의 피로가 임무수행에 밀접하게 영향을 미치며, 인적과실을 유발하는 주요한 원인 중 하나라는 사실이 밝혀지게 되면서 선박 인간공학분야에서의 인간공학적 요소들의 고려 여부가 관심의 대상이 되고 있다. 선박근무자의 피로 발생원인은 명확히 밝혀져 있지 않으며, 선상작업에서 오는 스트레스, 감정 및 작업 등에 의해 영향을 받는 것으로 보이나, 통상 피로는 주로 한 가지 원인보다 복합적인 원인에 의하여 발생되는 것으로 알려져 있다. 본 연구에서는 이러한 선박근무자의 자각피로도와 직무스트레스의 효율적 관리를 위하여 선상에서 간편하게 자각피로도를 측정할 수 있는 방법을 제안하고자 한다.

Seasickness not only makes persons on board vessels to vomit but also causes vertigo, headache, sleepiness, fatigue, lethargy and other discomforts. This ailment leads to disturbance of biorhythm and decline of perception which would eventually cause reduction of situational awareness among ship's operators that leads to marine accident. This study is about the sensitivity of people onboard ships to seasickness and focused on deck or navigation officer cadets(apprentice officers) and engine officer cadets(apprentice engineers) who have no previous experiences on board. It is conducted by using motion sensor that can measure ship's X, Y, Z-axis motions and through the questionnaire survey, and evaluated each students' degree of seasickness symptoms. Through this study, in same circumstance, we have known that there are different degrees of motion sickness for wheel house worker and engine room worker, It also confirmed that seasickness have high relationship with degree of hull motion and also, with cycle of hull motion. In addition, we have confirmed that Z-axis hull movement has higher relationship with seasickness than X-axis and Y-axis hull movements. This study aims to initiate additional researches about X-axis and Y-axis of the ship's motion which it expects to greatly enhance safety of wheelhouse and engine room personnel, ship's livability and comfortable sailing.

The multi-function console system in ships has currently exposed operational difficulties due to its complex interfaces although it supports a variety of functionalities. In this paper the concept of a human computer interaction (HCI) based multi-function console system is proposed, which can support intuitive operation environments by the analysis of users' needs to shipboard systems. Expert interviews and surveys are carried out in order to obtain users' requirements. Through the survey results, the HCI based multi-function console system is conceptually designed, which is optimized to the input of multi-touch screen. It is expected that the HCI based multi-function console system can provide ship operators with easy interfaces to the console system as well as safe operation in a rough ocean environment.

According to the development if the ships navigational equipment, a bridge system has been improved but a marine accidents by human error haven't been reduced Recently our interest is concentrated on a suitable ergonomic arrangement and design of the ships bridge equipment to reduce an error due to human factors. The bridge alarm system should be designed to recognize the alarm informations as soon as possible and to deliver it clearly. Internationally, the matter is being discussed on the BAMS(Bridge Alarm Management System) in a view if a ergonomic bridge design, but a practical design method is not getting result.. In this paper I would like to review an application approach of human engineering ergonomics to a bridge alarm system and propose a conceptual design if the Ergonomic Integrated Bridge Alarm Management System(EIBAMS)

The container has the inherent number which for distinguish among containers. When containers were handled, the container No. identify work must be precede. The work goes by fond in Most of the ports. It has not only inefficient time and cost but also error as worker's condition. The measure is operated that to use the camera on the spreader of quay crone to solve that problem. This measure, however, showed up the difference q recognition rates at weather, camera's condition, etc The ways could be considered both improvement of hardware and conversion of error number to solve the measure. This paper defines the problem and study an efficient solution.

According to the development of technology of the navigational equipments, many bridge equipments have been improved, however, marine accidents by human error have not been reduced. Therefore, a matter of primary concern is focused on whether bridge equipments of ships are ergonomically arranged to reduce errors due to human factors. As part of a design of IBS(Integrated Bridge System) standard, rules of the conning display to save time and additional movements to obtain important informations of a ship should be established as soon as possible. In the present study, ergonomic design factors for the conning display are studied through the survey of related works, heuristic evaluations, sketch method tests as well as questionnaires. Using these factors, new conning display was designed and the ergonomic indices were evaluated by comparing tests of the existing conning displays. It is found that the designed conning display obtained high ergonomic index showed better performance, therefore, the ergonomic index studied in the present paper can be used as a useful design standard in the conning display design procedures.

This study intends to verify the effectiveness of incentive schemes at Busan Port' aimed at promoting transshipment cargo. The current incentive schemes of Busan port intended to increase the T/S cargo volume have been disputed constantly. It is imperative, therefore, to restructure the system in accordance with the planned strategy. In this study, in order to ensure objectivity of the incentive schemes, all the parties (carriers, terminal operators and Port Authority) with a direct interest are answered and analyzed using the AHP methodology. Effectiveness is the top priority in the analysis of beneficiary validity of incentive schemes, when incentives are provided to Global overseas carriers compared with Global national carriers, IntraAsia carriers and Terminal operators. In the analysis of incentive schemes, direct cash support corresponding to the quantity of the T/S cargo had the highest effectiveness compared with exemption of port dues, cost compensation, port infrastructure support and subsidy for the service opening. The study results, therefore, reference the Port Authority when restructuring the schemes. This study has been conducted only focusing on the Busan port; however, the findings may have significant implications for overseas Port Authorities intending to implement incentive systems to promote cargo volumes similar to those at Busan port.
