When a multinucleate cell of Bryopsis plumosa was collapsed by a physical wounding, the extruded protoplasm aggregated into numerous protoplasmic masses in sea water. A polysaccharide envelope which initially covered the protoplasmic mass was peeled off when a cell membrane developed on the surface of protoplast in 12 h after the wounding. Transmission electron microscopy showed that the protoplasmic mass began to form a continuous cell membrane at 6 h after the wounding. The newly generated cell membrane repeated collapse and rebuilding process several times until cell wall developed on the surface. Golgi bodies with numerous vesicles accumulated at the peripheral region of the rebuilding cell at 24 h after the wounding when the cell wall began to develop. Several layers of cell wall with distinctive electron density developed within 48-72 h after the wounding. Proteome profile changed dramatically at each stage of cell rebuilding process. Most proteins, which were up-regulated during the early stage of cell rebuilding disappeared or reduced significantly by 24-48 h. About 70-80% of protein spots detected at 48 h after the wounding were newly appeared ones. The expression pattern of 29 representative proteins was analyzed and the internal amino acid sequences were obtained using mass spectrometry. Our results showed that a massive shift of gene expression occurs during the cell-rebuilding process of B. plumosa.

Building is different from the general commodities and needs to maintain the function and performance to get the living condition. Building deterioration occurs naturally with time elapse. Deterioration reasons are various. These are physical, functional, social and second physical aspect. Building would inevitably be deteriorated and need to repair various building part and materials. It gets to arrive at repair or rebuilding time until any management activity is meaningless. It is important to decide the rebuilding time in a management cost. In this paper, it aimed at analyzing the management annual cost and provide a rebuilding time of a apartment housing with a deterioration curve model. Results of this study are as follows : Most of the building has started to deteriorate in 40 years when the performance of building downgrades to 20%. After it past about 40 years, the deterioration rate is faster than the earlier 40 years. Fourth, the rebuilding time of an apartment housing is recommended about 45 years if the building service life has 60 years.

This study aimed to evaluate the TAC policy and to examine the effective annual TAC quota in the sandfish stock rebuilding plan using a bioeconomic modelling method. In the analysis, first, a sandfish bioeconomic model was developed by combining a sandfish stock population model and economic models by fishery and second, achieving stock rebuilding targets and changes of fishing revenues by the level of annual TAC quota were examined. Model results indicated that the TAC 1,500ton policy would have the greatest impact on the increase of sandfish stock biomass comparing to the status quo and other TAC policies. In addition, it was evaluated that the total fishing revenues of coastal gillnet and danish seine fisheries could be increased the most in the TAC 2,500ton policy. In both cases of TAC 3,500ton and 4,000ton, the fishing revenues of both fisheries were inversely reduced due to the decrease of catch by coastal gillnet and the decline of market prices by danish seine's excessive catch. Furthermore, they would have a negative impact on sandfish stock biomass.

Although there are many old school buildings that is more than 40 years in Korea, it is difficult to rebuild all of them due to limitations in budget management. Therefore, objective feasibility evaluation criteria are necessary to determine which school buildings should be rebuilt preferentially among the numerous old school buildings. One of the rebuilding feasibility evaluation items, economic evaluation generally requires documents such as construction statements and facility drawings. However, because most buildings older than 40 years do not have these documents, an economic analysis model that requires only basic building information should be developed. In this study, the economic analysis model that can be used for evaluating the rebuilding feasibility only with the number of years, total floor area, and structural information of school buildings was established. This model can contribute to the objective feasibility evaluation of old school buildings because it can evaluate numerous buildings on the same criteria based on basic building information.

The Fish Stock Rebuilding Plan (FSRP) is evaluated as one of the most effective fisheries policies domestically and internationally. FSRP is a comprehensive fisheries policy, including target stock size, rebuilding period, application of management measures, and participation of fishermen. The performance outcomes of FSRPs have been partially evaluated for recommendation for stock rebuilding in Korea, while they are fully evaluated in other countries that have implemented FSRPs. The performance evaluation system for FSRP is very needed to enhance its effectiveness as one of fisheries policies. That is, the system where problems can be reconsidered, achieving targets can be evaluated, and the plan can be modified should be implemented. This study classified the performance evaluation of FSRP into the economic evaluation as a quantitative analysis and the policy evaluation as a qualitative analysis. In the economic evaluation, the sustainability of fishery resources, the stability of fishing business, the efficiency of fishery production, and efficient utilization of fishery resources can be considered. As analytical methods for the economic evaluation, the bioeconomic model, efficiency estimation model, the dynamic MEY model can be utilized. The qualitative evaluation is to assess the qualitative performances of FSRPs, including interviews and surveys with fishermen and fisheries experts. In the survey, many different items can be included by evaluation factors which are related to policies such as timeliness, transparency, effectiveness, etc. In addition, the study suggested the performance evaluation system and procedures for objective and efficient evaluation of FSRPs. In order to practically apply the developed performance evaluation model, the pilot project is needed. That is, from the application of pilot project, detailed research methods, effective procedures, and evaluation factors can be investigated.

Based on Clark and Munro's theory of dynamic optimization between fishery resources and production, this study is aimed to take an empirical analysis of optimal production level to the Danish Seine fishery under the sandfish stock rebuilding plan. For empirical analysis, it examined the optimal fish stock size, production and fishing effort levels and it also made an additional evaluation of optimal production changes on main variables by sensitivity analyses. When a 4% of the discount rate is assumed, the optimal sandfish production of Danish Seine fishery would be 3,049 t, and the sandfish optimal stock size is evaluated to be 19,016 t. In addition, the optimal fishing effort is estimated to be 4,368 days. Accordingly, to achieve the optimal production level, current fishing efforts should be reduced while the fish stock size should be increased up to the optimal level.

This study is an empirical research to find out the effect on the management performance of hidden champions of food manufacturing companies when using blue ocean strategy for new product development. In order to achieve the purpose of this study, we conducted a questionnaire survey on hidden champions in the domestic food manufacturing industry and proceeded empirical analysis. When small and medium-sized enterprises in food manufacturing industries develop a new product, searching for non-customer, rebuilding the market boundary, and linking the external networks have a significant impact on their management performance. However, the fair procedure did not have a significant effect on the management performance. In terms of relative influence, rebuilding the market boundary was most affecting, followed by searching for non-customer and linking the external networks. On the other hand, this study implicated the management performance of hidden champions of food manufacturing industries when new products is developed by using the blue ocean strategy. Obtained results are as follows. If small and medium-sized enterprises of food manufacturing industries develop new products, it will be able to improve the management performance by utilizing strategies such as searching for non-customer, rebuilding the market boundary, and linking the external networks. In particular, the rebuilding the market boundary among the blue ocean strategies has a relatively high impact on management performance.
