Woods have been the familiar constructional materials because they were well suited to natural environments of Korea in terms of history regionalism and nationality. Since the modernization of Korea the wooden structure have mostly disappeared because of constructional costs regulations and convenience. But wooden constructions will reappear because of a prediction of wood demand and supply various choices for life circumstances and various investigations. There are many such cases. Among them Japan became an interesting object of investigation. New wooden constructional structures with new materials and modern skills may be observed in Japan. The purpose of this study is to trace architects' consciousness and to analyze constructions with the combination of wooden and other materials in Japan. Thus we explore a possibility to construct a new wooden structure which is suitable in modern Korea. The results were as follows: First the consciousness of Japanese architects' mixed wooden construction corresponds to the close relations between society and environment. Second the space of a structure with mixed wooden constructions in present Japan is chosen as the best way to consider functions and environments according to the form of need space scale and quality. Third the structure wooden constructional structure is a part of roof open space. in this case woods are represented and composed of japanese traditional wooden structure with new technique. Forth a mixed wooden construction has been used through a merit of each material by mixed of different materials as well as beauty of form.

Response-based approach is getting more preferred in determining the design sea-state for offshore structures because traditional environment-based approach is known to yield a much conservative design condition. This paper introduces the inverse first-order second-moment (IFOSM) method as a response-based approach, which is expected to give a more feasible design condition at the cost of reasonable number of motion analyses. The IFOSM method is based on the theory of probability and adopts an optimization scheme to determine the design point. Both the design maximum response and design sea state can be obtained straightforwardly from the optimum. The IFOSM method has been applied to a turret-moored FPSO's design problem and showed its effectiveness in practical use.

We found the similarities and differences it the works of Italian Architects especially in 1960s Neo Rationalism and also in the products of inclination of contemporary Minimalism. Based on the moderate application of traditional architectural language and on typological prototype the Italian Architects pursued inherent logic by which the works came to the composition and association rule that show an extremely moderate expression of a spirit indispensable to Architecture. And they turned down the logic of ergonomics but they searched for the simple and prototypical form that was the architectural language strongly restrictive common and objective all through the abstraction of Architectural elements in their memories. The overcome from the forms and the methodology of thinking contain common types in Contemporary Minimalism. But Contemporary Minimalism rejects fundamentally the analogical interpretation and typological protiotype from the past.

A three-dimensional finite element model has been used to simulate the bead on plate welding of curved steel plates having curvature in the welding direction. By using traditional method such as thermal-elastic-plastic(TEP) finite element analysis. the weld-induced deformation can be accurately predicted. However, three-dimensional finite element analysis is not practical in analyzing the weld-induced deformation of large and complex structures such as ship structures in view of computing time and cost. In this study, used is the equivalent loading method based on inherent strain to illustrate the effect of the longitudinal curvature upon the weld-induced deformation of curved plates.

In general, preliminary hull form design is performed by changing a parent hull form using a computer to satisfy given requirements, e.g., principal dimensions, displacement, $L_{CB}$, and etc. Principal dimensions, $C_b,\;L_{CB}$ and midship sections are the only parameters to be modified in the traditional hull form variation methods available for preliminary design. In this paper, a method is presented in which local cross sections as well as principal dimensions and midship sections are modified according to design requirements. The method gives hydrostatic curves of modified hull form simultaneously. An optimization technique to satisfy the constraints of hydrostatic characteristics such as maximizing KM as a design requirement is also considered.

Novel ships are commonly required iterative hull form modifications until she get reputation for new marine environment. Small FRP boats are manufactured in a identical shape with a mould. It implies that every modification step requires great time and expense which makes it difficult to improve the hull form promptly. Domestic hull form of small fishing boat of force has been evolved from the traditional hull form of developable shape. Utilizing this typical developable characteristics of small boats, ,New mouldless production method for FRP boat has been suggested and it is confirmed that the method is recommendable for a petty order of hull in evolving period of hull form development.

As Indonesia determines to increase its marine fishery production, the development of tradi-tional boatyards has to be included in the agenda as it will give the local fishing communities a better chance to compete with large capital intensive fishing companies. It will also spread job opportunities evenly throughout the country instead of concentration fishing vessel con- struction in a few large shipyards located primarily on the highly populated island of Java. However development every single boatyard in indonesia would not only be prohibitively ex-pensive, but it would also create social tensions as the introduced technology would not be immediately accepted by the rural societies whose own traditions are still culturally signif-icant. Both these problems can be reduced by developing a collaborative scheme between traditional boatyards and a larger shipyard. The shipyard, with modern facilities, can develop work packages containing knock down components which are then assembled in the tradi-tional boatyards. The work packages are planned and designed so that every component can be assembled with relatively simple tools. Radical changes can be avoided as new techniques can be introduced gradually, responding to the boatyard\\`s own requirements and aspirations. While this manufacturing procedure is conceptually straightforward its efficient implemen-tation is in practice complicated by the fact that each traditional boatyard has unique char-acteristics in terms of labour resources, technological capability, and transportation links. By developing a computer model to simulate the interaction between the main shipyard and small traditional a computer model to simulate the interaction between the main shipyard and small traditional boatyards work packages can be designed that ensure that activities at all manufacturing locations are efficient.

This study deals with the method of constructing and repairing column, important element of traditional wooden building. Column should have long-lasting strength and resistance to decay and vermin because it is more important in role of structure than in that of ornament. And the rotten or the split part of wooden column should be repaired regularly or irregularly. First of all, this study treats of general character related to the life length and strength of wood. Then it describes the technical method of choosing proper wood for column and that of carpentering, painting, and mending wooden column.

This study examines the details and characteristics of prizewinning plans of Cho-Sun housing plan competition promoted by Daily Cho-Sun Company during Japanese colonial period. The main features of Cho-Sun housing plan competition were that the competition held with an application of popular newspaper readers and a judging committee was composed of only Korean architects, especially Park, Gil-Ryong as the president of the board of examiners. Cho-Sun housing plan competition put ideological factors for the improvement of living as like advancing to the cultured(modem) life, respecting for family life, respecting for privacy of family members and so on. First of all, the competition suggested the direction of the improvement of dwelling spaces which focused on making harmonious home life. This study found common characteristics of prizewinning plans of Cho-Sun housing plan competition as the result. First, Cho-Sun housing plan competition introduced a centralized house plan as a model of the improvement of small-sized houses. Second, architectural orders of western or Japanese style mingled with ones of korean traditional style in prizewinning plans as entrance hall, western style reception room(parlour), maid's room, bathroom for example. And a manner of seating using chairs was brought into the style of living which would be assumed in the prizewinning plans. Third, traditional way of composing dwelling spaces was maintained, receiving the characteristics of dwelling spaces of japanese style simultaneously, which central corridor was put at the heart of house for improving arrangement of rooms and flow lines. Fourth, lavatory and bathroom were placed inside of the house.
