Ships and their cargos have been managed safely by positioning report system. However, little attention has been paid to safety of crew's works with danger. The attempt that used PHS inboard was before by the present authors. However, the functions were just voice call and mail exchange. The data acquisition from the terminal by proper control was not possible. Thus the position of the terminal was not available. As for the cell phone of next generation, GPS receiver and wireless LAN are installed by manufacturers. Therefore, we propose a system which uses a cell-phone with GPS receiver on a ship in order to promote the safety of ship's crew. We checked the availability of cell-phone GPS receiver at thirty different points inboard. The positioning was not possible in the areas further than 4m from the window. Then, we proposed the system which follows the positions of the crews and confirms their safety inboard by using the VoIP (Voice over Internet Protocol) function by wireless LAN.

Urinalyses have been conducted for 28 crew's in H University's training ship and creatine and uric acid turned out to be higher in all ages, which can be inferred that board job has caused negative impact on kidney and/or malfunction In addition, TC and HDL-C, LDL-C ha; decreased, however, TG has increased after the navigation. All different positions including officer, crew, decker, engineer and radio part showed the similar pattern TC and HDL-C has decreased in 30s, 40s and TG has increased in 30s. A few of the 30's show extremely high TG rates so hyperlipidemia is suspected. 7 members turned out positive for UBG test and 5 positive for PRO test. Especially there was only one UBG positive before the navigation but, 7 members has become positive, which means the one-month long-tenn navigation has definite impact on the liver cell function.

With the terrorist attacks on 11 September 2001, the ships and their crew' safety and security have become a major issue in the maritime industries, In high-risk terrorism, not only ship owners and port authorities but also crew members on board should take precautions in the conduct of their business. In this paper, the vulnerability and essential elements in overall security of merchant ship are analyzed with a discussion in depth of the concept and principles of maritime security of merchant ship are analyzed with a discussion in depth of the concept and principles of maritime security management. And then, ship's security model and security system to reduce security rish and to minimize damage are proposed.

This study examined the significance of the crew's professional consciousness and sought to clarify the differences in the professional consciousness of crew by considering biographical characteristics of the crew and onboard working situations, which were expected to influence the professional consciousness of crew. The empirical analysis showed the crew's individual characteristics such as age, marital status, position in ship organization and nationality significantly influenced professional consciousness. The comparison in the differences of professional consciousness level among crew's nationalities showed that the professional consciousness of Filipino crew was the highest, and in the descending order of Indonesia, Myanmar, Chinese, and South Korea. The analysis results of other variables of on-board working characteristics showed that as crew's satisfaction of welfare increased, crew's professional consciousness increased, whereas the feeling of isolation from home and society had a statistically significant negative (-) impact on crew's professional consciousness. Furthermore, the analysis of multinational crew manning characteristics stated that cross-cultural acceptance did not have a statistically significant impact on the crew's professional consciousness, while cross-cultural adaptability had a statistically significant impact. This study emphasize the importance of the crew's professional consciousness and suggest how to enhance it, which allows crew to continue their career with the charm and pride of their profession.

The human being continued the processing of improvement for well being life according to scientific results The other hand, All the seaman life take the rest and sleep in ship's office and living room. In this case, many crew took the pain of back spain or deposit the his fatigue, This will be decrease the productivity owing to crew's back spain or fatigue etc. In this study researched the problem of ship's bed mattress and the principle of Well being air mattress in technical standard etc. Specially decreased some kinds of bacillus, germ and many kinds of bacteria by using of tourmaline which emitted the far red light and negative ion from surface of the mattress. We developed and applied the ship's Well being air mattress to off shore and various kind of ship by International Labour Organization convention 192.

The purpose of this study is to investigate the effects of the job stresses perceived by R.O.K. naval crews on turnover intentions and job satisfactions. Especially, this study aims to derive the policy implication for the trait characteristics by comparing the job attitude between the surface naval ship and submarine crew. For this purpose, we surveyed 1,000 naval crews. Then, multiple regression analysis was performed. Next, a T-test was conducted to test statistical significance of group differences. First, the job stresses perceived by naval crews were higher in the order of physical environments, overworks, compensation incompetence, lacks of autonomy, and conflicts with people. Second, the job stresses perceived by submarine crews were higher than that of surface naval ship crews. It was also proved statistically significant by the T-test. Third, the physical environments, lacks of autonomy, conflicts of relativity, and inadequate compensation stress have a positive statistically significant effect on turnover intentions of naval crews. Fourth, lacks of autonomy, conflicts of relativity, and inadequate compensation factors have a statistically significant negative effect on the job satisfactions of naval crews. Finally, multiple regression analysis was performed between the independent and dependent variables of the naval crews, and the policy implications were derived.

The ship management industry in Korea is on the decrease since the latter half of 1980s. The ship management companies in Korea today has been confronted with a severe business crisis beacause of the pressure if rising coasts, marine environmental protection under the slowdown, to evade become a crew. This is a study on a revised bill of the related laws and regulations for revitalization of ship management companies.

In this study, we used the program of three-dimensional analysis of fire for analyzing visibility of smoke flow and temperature of the accommodation area what is required for the analysis of survival of the crew. In particular, I would like to propose a method for reducing the flow rate performance in order to reduce the suffocation from the smoke of the majority of personal injury. Existing vessels are designed to close the fire door automatically when the fire alarm issued. When there is no crew that dared to escape, it can delay the spread of fire and smoke flow which is determined to be very useful to improve the survival rate of the crew. However, it can be fatal to the crew whose rooms are located on the inside of the fire door that has not completed the evacuation. In this study, we check the smoke flow rate and rate of temperature rise when crew open the fire door what is closed due to fire and compare to the structure of the blocking layer.

Recently, all areas of IT has been rapidly in land. As a result, the location is very important in everyday life. But in ship are limits network with communication Equipment and service. As a result, be far removed from information age. Currently, ship is connected with the outside world via satellite on the voyage. But, because high billing, ship is possible data transfer using low speed bandwidth. Because ship is not possible using LAN, only limit ship's crew some use internet in limited space. So, ship is required construction of the network. In this paper, because composition of basic IT environment with information need of crew and customer from ship to cruises, there construct LAN in ship and propose network design for network of ship.
