This study purposes on continuing experimental research of furniture form creation focused on the importance and necessity for a-formal concept for designers to drift away from general acknowledgement and practice routine to design more radical forms for meeting various needs of late industrialized society, which have not been satisfied with formal and universal designs. This study covers presenting new points of view on research for designers to look for different solutions to widen their consideration in the process of furniture form development and to set up academic data base with the case studies of designers in anti-construction concept to define their experimental challenges for new design form creation, on the basis of overall research on the effects and roles of a-formal approach in the furniture design form creation.

The purpose of this study is to establish the theory of the spatial composition that is 'The Structure of Relation' in Korean traditional houses. This study has been focused on the spatial composition of Hyangdan. The form composition is an element defining primitive functions and space and producing aesthetical effects, where 'quality as a substance' is not important but 'quality as a relation' is essential. Quality as a meaningful relationship comes from realization and regulation of visual attributes among form elements. Each form compositional element establishes the hierarchical structure logically with the entire order, In order for the quality of all form compositional elements to be clarified as a meaningful relationship logically, 'compositional concept' which combines a series of form elements into the grammatical dependence to a specific direction, has to be assumed. If the intrinsic relationship among a series of form compositional elements fails to confront with the 'contextual concept' which eventually indicates unique conditions for a place according to the refined compositional concept, the result of form composition never leads to a specific solution

This study was carried out for the hull form development of G/T 340ton class high speed fishery patrol ship by Chosun University at the Circulating Water Channel cooperatively with Korea Maritime Service. Same size of 15knots class fishery patrol ship was selected as a parent form (Model number : CU-015), and modified fore and after body to be suitable for the operation at 20 knots. To minimize the breaking wave in the vicinity of fore body at high speed zone, high bulb nose and slender fore body hull form was chosen as an initial condition. Meanwhile, to ensure the engine room space keeping high resistance-propulsion performance, U-type stern hull form was developed.

A general curve and surface is a basic method to generate Free-form object using the fundamental properties of blending function. In typical method, there is an overhead of calculating to present Free-form object with the line segments and interpolation algorithm, In this paper, for resolving this problem efficiently, it will propose the flexible Free-form curves/surfaces using Ball curve shape-preserving property. This method includes Geometric Continuity that is needed to design Free-form Surface of high degree consisted with many curves. Also, when lots of data are reduced using Geometric Property of Free-form curves, the shape-preserving property of resulting object can be maintained, then it can represent any Free-form object with less calculating .

Our Country are called as a suzerain State of fermentation food, and preservative Technique was developed, because the specific character and the form of pottery were the best superior utensil of storage. The form couldn't give an explanation with scientifically, but we have used it for a few thousand years, which must get transformed from most compatible and reasonable form of fermentation. At present, a pottery was disappeared by the growth of the industrial society, and even the scientific form concealed it looks. For that reason, we apply the form into looks of a modernistic mechanism, and it intends to suggest a new direction to better the pottery of a formentation food.

The purpose of this thesis is to make clear particulartity of young adult generation which leads industry in their demands so that fashion trends are foresaw, and to describe style of costume satisfied with picture of new male. This thesis is to consider young adult style of costume in terms of double root described by W$\ddot{o}$lfflin in the internal meaning and the external form, so as to analyze their unique style. In conclusion, domestic young adult style of costume is embodied in the internal meanings of individuality, aestheticism and new classicism in terms of the external forms which means body-priority-form by open-form, whole-form, integration-form, rounded-form, indeterminate-form. With these results, domestic fashion industry is demanded to be from classic to modern expressions so as to be reflected in sophisticated masculinity of young adult.

This paper presents a mathematical method that represents efficiently high-speed coastal fishing vessel. That is, it represents the numerical hull by using irrational function and hull form characteristic curves, which define a hull form under design conditions. Then it suggests a process that hull form characteristic curves are represented with NURBS and hull form is varied.

Double-stranded RNA (dsRNA) viruses and single-stranded RNA(ssRNA) viruses were detected in a strain of Pleurotus mushroom cultivated in a farm. Those fungal virsus were purified in the pH 6.0 or pH 7.2 using CsCI or Cs$_{2}$SO$_{4}$ buoyant density centrifugation. Each viral particles were not completely separated at any trials. However, mushroom bacili-form virus contains a single major nucleic acid with 0.7 Kb ssRNA, which might code for 20 Kd viral capsid protein. The dsRNAs are encapsidatred into spherical-form viruses, whereas ssRNA viral genomes are encapsidated into two different sizes of bacili-form particles. A healthy-looking mushroom also contained some spherical-form viruses with dsRNAs. Laboratory strains of Pleurotus ostreatus and a cultivated strain of P. sajor-caju did not show any viral particles. Mushrooms with specific disease symptoms. however, contained at least four different sizes of spherical-form viruses. Thus, we concluded that a bacilli-form virus case a severe disease symptoms of adnormal on mushroom development.

Handling performance of a vessel is greatly related with her steering characteristics which consist of two kinds of motion characteristics ; namely course stability and turning ability. The correct prediction of the qualities, especially the steering characteristics is as much important in ship handling as in ship design. It is the purpose of this paper to provide ships handlers better understanding of steering characteristics and then to help them in safe controlling and maneuvering of vessels presenting distinct inherent steering characteristic difference that lies between a fine-form vessel and full-form vessel. The authors calculated dynamic course stabilities of two kinds of ideal models, one of which represents a fine-form ship and the other a full-form ship, based on hydrodynamic data of forces and moments obtained by model tests in maneuvering tanks. The result of calculations indicated that a ship of full-form configuration has inhernet course instability. Though significant nonlinearties affect ship montions in maneuvers, application of linear theory is sufficient for prediction of the maneuvering characteristics of vessels on calm waters for handling reference.

Currently, free-form building has been increased worldwide. However, as a finishing material of free-form building, the production of free-form concrete panels(FCPs) spends lots of cost and efforts since it is difficult to reuse the FCP formwork and lots of workers are needed to make free-form curve. In addition, the technology to produce the FCP economically and easily is insufficient. Therefore, the objective of this study is a basic study regarding production management for developing free-form concrete panels. To achieve the objective, the property of FCP and condition for effective production management and production process are analyzed. The results of this study can utilize to develop the algorithm for FCP production management.
