This study analyzed and mutually compared the fishery manpower problems in Northeast Asia region including Korea, China, Japan by fishery industry structure, fishery education, fishery manpower and presented fishery cooperative schemes of Northeast Asia. In case of fishery manpower problems, China is still in a better situation whereas Korea and Japan have a hard time of a labor shortage. Korean companies have employed foreign crews to find a way out of the difficulties and the foreign crew rate is growing but the problem is that the reduction of Korean crew could deteriorate the safety of vessel-sailing, efficient operations, and fishery efficiency. Therefore crew management should be placed focus on improvement of working conditions and guarantee positions to foreign crew as assistants in fishery surroundings and systems. Fishery manpower problems are complementary to each nation in Northeast Asia. In consideration of this fact, fishery manpower management needs the mutual fishery manpower and information exchange and for the sake of it, the most urgent task is to build up the international fishery cooperative network through establishing fishery-related information systems of Northeast Asia.

This study focused on the supply-demand and training system of the crew for domestic coastal shipping. First of all, it forecasted the prospect and effect in the future of the crew supply-demand through the analysis to the current situation of crew employment and the internal and external environment changes. Next, it suggested the specific role and alternatives of government, industry and educational institutions after the comparison and examination of the sailor policies among Korea and major shipping countries. In regard to the demand of crew manpower in coastal shipping, it figured out the bottoms and the current circumstances of sailors, and it could anticipate the future demand by the gradational approach. According to the findings, firstly the result of this simulation by the changes of the ship numbers demonstrated that the demand over the next 10 years will be 7,890~8,025 in the case of the growth 0.4%, and 7,894~8,063 in 0.5%. Secondly, assuming the growth 0.1~1%, the result illustrated that the demand will come to 7,879~8,258. This means the fact that the additional manpower has to be input to 20~430 annually from now on. To conclude, this study showed the more rational numbers about the supply-demand than the past researches and displayed the systematic approach to supply and train the crew in domestic coastal shipping.

In this study, it was accomplished to analyze the productivity and manpower through the activity of rebar work for the application of rational construction cost in apartment house. And the rebar work is very important in the view of the expense and safety, and durability in the construction of R/C structure. Also the rebar work is very affected with productivity owing to the lack of manpower and materials cost rise.

A decrease in the fertility rate leads to a reduction of troops, so the need to efficiently operate the troops is growing. Therefore, it is necessary to develop a system for estimating warship manpower. In this study, system development was performed according to the CBD methodology. The user requirements were defined and the system function that satisfies the requirements was derived. And through the development process, the CBD methodology and the systems engineering process were compared. As a result, similarities were confirmed in the analysis and concept design stages, so the possibility of merging the two processes was suggested.

This study aims to make improvements to the standard estimation process used to estimate reasonable costs for construction work, and to suggest a work crew based estimation using a new cost estimation model. In addition, work crew shift combination and construction process were systematically organized in order to improve the estimation technique and the construction capability of the cement liquid waterproofing work for apartment buildings. In addition, in terms of manpower and productivity, analyses were performed on the cement liquid waterproofing work for apartment buildings with net areas between $84-85m^2$ and $125-184m^2$, and the results were then compared with those calculated using the conventional work-crew based estimation method. Through this study, when the results of this study and those calculated by the conventional method were compared, for apartments with the net area of $84-85m^2$, the differences between specialists were shown to be 1.91 times to 2.13 times on average, while they were 8.82 times to 9.52 times between normal workers on average. For apartments with the net area of $125-184m^2$, the differences betweenspecialists were shownto be 1.89 times to 2.07 times on average, and 8.57 times to 9.38 times on average between normal workers.

In this study, it was accomplished the analysis of apartment house shape and the work factor productivity of the form work for the application of rational construction cost in apartment house. The form work is highly depended on the manpower in frame construction, and it has been a high impact during estimating of frame work cost.

The process of railway traffic planning is composed of several steps such as long-term, mid-term. short-term, and real-time plan. The planning of vehicle and manpower resources is a main research topic in tactical short-term planning step. Railway vehicle is usually consisted of a power car, passenger/freight cars and human resource is composed of engine driver, cabin crew, ground personnel. So far, power car was main research target in railway vehicle scheduling problem. Recently according as the light electric railway or high-speed railway is introduced, the operational planning of trainset vehicles become important, In this paper, we introduce the conceptional model for trainset restoring problem and developed heuristic algorithm.

As cyber threats in the maritime industry increase due to the digital transformation, the needs for cyber security training for ship's crew and port engineers has increased. The training of seafarers is related to the IMO's STCW convention, so cyber security training also managed and certified, and it is necessary to develop a cybersecurity training system that reflects the characteristics of the OT systemof ships and ports. In this paper, with the goal of developing a training model based on the IMO cyber risk management guideline, developing a cyber security training model based on the characteristics of maritime industry threats, and improving the effectiveness of cyber security training using AR/VR and metaverse, A method for developing a system for nurturing cyber security experts is presented.

The construction progress control is very important because there are many unexpected factors affecting time schedule delay and cost overruns. A complicated measure including item quantity and inherent time and costs is used to monitor the progress. Another element to be considered is a productivity, which is cost effectiveness because productivity is primarily measured by the costs. Productivity is stated as constant in-place value divided by inputs such as worker-hour. The main purpose of this paper is to analyze the productivity of structural formwork using a 3D BIM. In order to achieve the research objective, an integrated model of a BIM with a daily foreman's report is developed. The quantities being extracted from a 3D model and information are integrated with manpower utilized. The developed model is applied to a case project to measure and analyze the productivity in terms of individual building and work crew team. The results are discussed and further research topics will be addressed.
