The design process becomes more difficult due to the increasing complexity of products. Thus, without any proper design experience, designer cannot handle his design problems systematically. Besides, the conventional optimal design method cannot be used effectively at the early design stage, since most design problems must be formulated in terms of objective and constraint functions based on the mathematical concepts of Operation Research. Thus, in this paper, new design concept based on FBS (Function-Behavior-Structure) design model is introduced to help the novice designer formulate the complex design problems systematically into a mathematical form. In this FBS model, function means the designer's new intents designer wants to create for, structure stand for a final product configuration and behaviour is a product's performance. FBS design model is thus rather totally different concept used for formulating design problem, compared with conventional optimal design method. To validate this new FBS model, 330K VLCC design case is performed, and we found, though it is one design example case, that this new design concept could be effectively used for future ship design problems since, during the formulating design problem, the only engineering terminology such as function, structure, and behaviour of design product is used based on the engineering concepts, instead of mathematical terminology such as objective and constraints.

This study was conducted to investigate the influence of the changes in handsheet structure by beating, wet pressing and the addition of wood flour spacer on the water absorption and the moisture absorption properties. The higher beating treatment of BKP resulted in the denser structure of handsheet samples, which leaded to the lower water and moisture absorption. The wet pressing showed the similar effects by reducing the bulk of handsheets. In case of the handsheet samples with similar bulk structure made of different beaten pulps, the severer beating treatment increased the water absorption and the moisture absorption. The addition of the wood flour spacer resulted in the higher bulk following the higher water and moisture adsorption. Since the water and the moisture absorption properties of paper products could greatly affect on not only the product quality but also the process runnability, the control of the water response of paper product has been considered as very important technology. The results of this study might be useful for control of water and moisture absorption properties of paper products.

Two key data areas of the integrated production database in computer-integrated manufacturing (CIM) systems are the product structure in the forms of bills of material(BOM) and the process structure in the forms of routings. The great majority of existing information systems regard the BOM and routing as two separate data entities, possibly with some degree of cross-referencing. This paper proposes new information structure called the bills of material and routings(BMR) that logically integrates the BOM and routings for the CIM systems in ship production. The characteristics of ship production are described as: 1) make-to-order production type, 2) combined manufacturing principles (workshop production and construction site production), 3) significant overlapping of design, planning and manufacturing, 4) very long order throughput time, 5) complex product structure and production process. The proposed BMR systematically manages ail parts and operations data needed ship production considering characteristics of ship production. Also, the BMR situated on the integrated production database more efficiently supports interface between engineering and production functions, and integrates a wide variety of functions within production such as production planning, process planning, operation scheduling, material planning, costing etc., and simplifies information flow between sub-systems in CIM systems.

건설프로젝트에서 현재 사용되고 있는 작업분류체계(Work Breakdown Structure)는 프로세스 내의 세부작업간 선·후행 관계의 불확실성과 작업의 불합리한 상호 연계성에 기인한 문제점을 내포하고 있다. 이를 해결하기 위해서 본 논문에서는 Work Structuring을 제시하여 프로세스간에 투명성을 부여하고 세부작업간의 간섭을 제거시켜 작업신뢰성을 향상할 수 있는 방안을 도출하였고 프로세스를 개선하기 위한 프로세스 디자인 다이어그램을 개발하였다. WS에 의한 프로세스 개선의 목적은 고객에게 가치를 창출시켜주면서 보다 신속하고 신뢰성 있는 작업 흐름을 만드는 것을 목적으로 하고 있으며 비가치 창출작업의 감소, 프로세스의 명료화 및 투명성 향상 등에 의의가 있다.

In order to understand the economic damage of economic sanctions on trade between Korea and Russia, a trade structure analysis was conducted through statistics on import and export trade between Korea and Russia. Through the structural analysis of product trade, we tried to accurately analyze the current status of product trade between Korea and Russia. In the trade structure analysis, it was confirmed that the trade in goods between Korea and Russia decreased the most in market share and trade concentration. However, trade specialization, comparative advantage by market, and intra-industry trade index were not significantly affected despite strong economic sanctions. from Russia's point of view Smart measures are needed to address the current situation to avoid a greater economic downturn. The end of the war and the restoration of partnership with other countries are considered the most beneficial solutions for Russia and all countries, but it is difficult to predict how the war will go or what economic situation Russia will be in after the war.

The purpose of this paper is to design a new management model based on the grill-formed product charscteristic area(PCA) which specify the position of products classified by the level of market and technology. This product characteristic area is composed of 9 cells and the cases sorted by market and technology are analyzed by each cell. Conclusion of this study based on many significant results gained by the various multi-variate analysis is summarized as follows; First, it can be noted that success/failure factor and progress stages are different by each cell. Second, a new management model is designed by combining the Motive Resource, Success/Failure(S/F) factors, and Progress Stages of New Product Development. Third, success products featured a balance between marketing oriented and technically oriented activities. A new attemp that combine S/F factors with development stages by each product cell will be of great usefulness for further study.

This study seeks solutions for two conflict values from the fair trade, one being fulfilling environment and social responsibility and the other being suggesting stylish designs within a reasonable price range. The purposes of this study were to establish fair-trade fashion product development process by investigating practices in fashion product development process within fair-trade company, and to identify the characteristics of fair-trade fashion product development. Qualitative research method was employed. Participant observation and in-depth interviews were conducted with practitioners working in fairtradekorea, Ltd. and producers in Bangladesh, from which case studies were compiled. The results were as follows: The case study provided evidence that fair-trade fashion product development has the same steps as practiced in general fashion brands, but has different characteristics such as fair-trade products going through a much slower process which led to early planning, having producer-centered product development, concentrating on spring/summer products, having a high cost structure, and having unpredictable quality control. Study implications and future research avenues are also discussed.
