Modern fashion can be expressed as 'pursuit of cocktail effect', which means not unformed, not bounded by a rule, and mixed with various styles. Among them, the most outstanding trend of style is the'infra-syndrome'which designs underclothes like a ordinary wear, which has outstood since early 1980s. In 1990s, this syndrome made active progress and now facing 21th century, it becomes one of the big trends in fashion. Clothes of infra syndrome are one of attempts for freedom expressed by progressive designers who pursuit new and surrealistic design. The purpose of this study is to maximize the aesthetic beauty of'infra-syndrome'apparel centering on dresses of which designs are notable derived from underclothes. With the sewing techniques using the special facilities of the lingerie-manufacturing industry and making use of new material which can be used far lingerie wear, this research strives to expand new ideas in the lingerie industry as well as to contribute to promoting the dress culture by developing novel lines from a new form of dress and lingerie-foundations of dress suitable for human body.

This paper deals with the problem of the optimal location of warehouses in the two stage distribution system, i.e., the distribution system where the product is transported from plants to customer areas via warehouses. The Problem is formulated with a zero-one mixed integer programming and an efficient branch and bound algorithm is then used to solve the problem. In order to obtain the solution of this problem, this paper shows the procedure of conversion of two stage distribution system into one stage distribution system. An improved method of solving the linear programming at the nodes and branching decision rule is also showed by this study.

At the economical crisis of Korea in 1997, self-determined price for apartment and the revision increasing the ratio of residential area for mixed-use residential building were introduced to activate the construction industry, which causes construction companies to build super high rise apartment discriminative and high class orientated. This study aims to classify the super high rise building which is planned to build or built recently and to analyze the architectural characteristics. The objects are 288 unit households in 26 apartment complexes higher than twenty five story since 1998. As a result, super high rise building comparing with existing apartments were being varied in plan types of main building and unit household and in construction types. As for the plan, the number of walls having opening to outdoor were increased and it is considered that high rise building can take advantage of a view, lighting and sunshine. The location of living room that used to be in the center of unit in existing apartment was moved freely without rule.

Nonlinear vibration and instability of cylindrical shell conveying fluid-nanoparticles mixture flow are studied in this article. The surrounding elastic medium is modeled by Pasternak foundation. Mixture rule is used for obtaining the effective viscosity and density of the fluid-nanoparticles mixture flow. The material properties of the elastic medium and cylindrical shell are assumed temperature-dependent. Employing first order shear deformation theory (FSDT), the motion equations are derived using energy method and Hamilton's principal. Differential quadrature method (DQM) is used for obtaining the frequency and critical fluid velocity. The effects of different parameters such as volume percent of nanoparticles, boundary conditions, geometrical parameters of cylindrical shell, temperature change, elastic foundation and fluid velocity are shown on the frequency and critical fluid velocity of the structure. Results show that with increasing volume percent of nanoparticles in the fluid, the frequency and critical fluid velocity will be increases.

VRP(Vehicle Routing Problem) is studied in this paper, where two different kinds of missions are to be completed. The objective is to minimize the total vehicle operating distance. A mixed integer programming formulation and a heuristic algorithm for a practical use are suggested. A heuristic algorithm consists of three phases such as clustering, constructing routes, and adjustment. In the first phase, customers are clustered so that the supply nodes are grouped with demand nodes to be served by the same vehicle. Vehicle routes are generated within the cluster in the second phase. Clusters and routes are adjusted in the third phase using the UF (unfitness) rule designed to determine the customers and the routes to be moved properly. It is shown that the suggested heuristic algorithm yields good performances within a relatively short computational time through computational experiment.

This paper deals with the instability analysis of concrete pipes conveying viscous fluid-nanoparticle mixture. The fluid is mixed by $AL_2O_3$ nanoparticles where the effective material properties of fluid are obtained by mixture rule. The applied force by the internal fluid is calculated by Navier-Stokes equation. The structure is simulated by classical cylindrical shell theory and using energy method and Hamilton's principle, the motion equations are derived. Based on Navier method, the critical fluid velocity of the structure is calculated and the effects of different parameters such as fluid velocity, volume percent of nanoparticle in fluid and geometrical parameters of the pipe are considered. The results present that with increasing the volume percent of nanoparticle in fluid, the critical fluid velocity increase.

Three types of plural forms are discovered in the ancient literature 《Chung-ui-jig-eon》: propositional plural markers placed in front of the main word - either noun or pronoun, postpositional plural markers placed behind the main word, and pro-/postpositional mixed plural markers. The Mongolian Rule in China during Yuan Dynasty caused the osmotic linguistic imperialism of the Mongolian over the Chinese language. Mongolian language - an Altaiian language which is postpositional - dominantly influenced the Chinese language - which is a propositional language. In addition, the previous usage of '輩', '等', '伟', '满' in Ancient Chinese, made it easier for '每' to be accepted and grammaticalized as a plural marker. The grammaticalization of '每' had been progressed through the reinterpretation of '每' in the structure of 'S(NP)+每+VP'. As a result, '每' had started to be widely used as a postpositional plural ending behind noun or pronoun, regardless of its position in the sentence.

This study is to reconsider the symbolic potential of the costume by investigating the role of cloth in Indian culture, noting the fact that Indians wore hand-woven cloth and adopted a flag with the spinning wheel in the center as part of their nationalistic programs for independence. The results are as follows; The Indian cotton industry had held the fist position in the world and spinning and weaving had been an Indian national industry until the early part of the 19th century. As for the Indian cotton industry under the rule of Britain, Indian was reduced to being a colony producing raw materials and a market of cheap British finished goods, and eventually fell into anarchy with economic poverty of the general public and peasants'uprising mixed with the complaint of the intellectuals. The Indian National Movement started as a resort to escape the British rule because of continuous poverty and social exhaustion, and its pivot was Gandhi. Gandhi launched a revolutionary noncooperation movement in Indian society with diverse races, religions and castes, and developed nation-wide campaigns such as Boycott, Swadeshi, the encouragement of spinning wheels, etc. Gandhi urged that Indians' weak identity and poverty were caused by the dissolution of their native craft and that the Indians should wear Indian products for economic independence. Accordingly, leaders of Indian National Congress regarded a spinning wheel as an economic necessity and national symbol, and approved manual spinning and weaving as part of their nationalistic programs in order to drew the general public to the nationalistic movement in 1920. They also decided that all Congressmen should wear hand-woven cloth, Khadi, and adopted spinning wheels as the logo type of Indian National Congress. Khadi, Indian national cloth, was a symbol of national unification, freedom and equality, and also a means of economic self-sufficiency, Swadeshi, and eventually led India to autonomy, Swaraji. Therefore, it can be concluded that the cloth converted Indias economic and political identity.

This paper presents a pressure drop correlation for evaporation and condensation of alternative refrigerant with oil in micro-fin tubes. The correlation was developed from a data base consisting of oil-free pure and mixed refrigerants in micro-fin tube; Rl25 R134a. R32 R410a(R32/R125 50/50% mass), R22, R407c(R32/R125/R134a, 23/25/52% mass) and R32/R134a(25/75% mass). The micro-fin tube used in this paper had 60 0.2mm high fins with a 18 helix angle. The cross sectional flow area $(A_c)$ was $60.8 mm^2$ giving an equivalent smooth diameter$(D_e)$ of 8.8mm. The hydraulic diameter $(D_h)$ was estimated to the 5.45mm. The new correlation was obtained by replacing the friction factor and the tube-diameter in Bo Pierre correlation by a friction factor derived from pressure drop data for a micro-fin tube and the hydraulic diameter, respectively. This correlation was also used to predict some pressure data with a lubricant after using a mixing viscosity rule of lubricants and refrigerants. As a result, the new correlation was also well predicted to the measured data within a mean deviation of 19.0%.
