  • Resent, requirement of residents is socially increasing for apartment. Apartment housing os developed to reduce the housing shortage caused by urbanism after industrialization in Korea. The Purpose of this study is to analyze the casual relationships of housing satisfaction, living Life-Cycle on all residents of apartment housing. This study develops a theoretical model based on the previous studies, and testifies the hypothesis through analyzing to questionnaires form 643 residents of apartment housing. Then, the data were analyzed by SPSS12+ program package in terms of frequency, correlation analysis and multiple regression analysis. The results of this study is summarized as the followings: The perceived quality had positive effects on the factor of living Life-Cycle and housing satisfaction. Finding of this study can provide valuable information for a criterion of decision making to consumer and a marketing strategy of housing construction company.

  • Castleman`s disease, giant lymph node hyperplasia, is a rare benign disease. The lesion usually consists of a single node, unassociated with any abnormality of the adjacent lymph nodes or other organs. In the first accounts of giant lymph node hyperplasia of Castleman, the lesion was described as solitary and localized to the mediastinum, which is still the most frequent site of involvement. The disease occurs in all age groups and there is no particular sex preference. It is symptomless and is usually detected on chest films as an incidental finding. On a single involvement, it does not recur after excision, whether total or partial, and the main indication of operation is to rule out more serious tumors. Recently multicentric form appears to be a variant of classic giant lymph node hyperplasia and is associated with significant morbidity and mortality. Histologically, two distinct types have been reported; hyaline-vascular and plasma cell. The hyaline-vascular type of lesion is much more common than the plasma cell type. We report two cases of the hyaline-vascular type of Castleman`s disease.

  • Den have been many construction projects in urban n We have a lot of problems which have to be solved especially against residence complaints existing building damage due to construction worts. We sometimes have to pay a certain amount of cost to solve the above problem, not in planning. In addition to, we have to suffer from work delay due to confronting problem. Almost all of these are due to blasting work to break solid rock to be excavated. Therefore, this study is focused on finding out how to reduce noise more cheaply. Four cases(4) as cheaper but more effective way have been tested to find out which way of local fence will have better moise reduce function in a field site. Where five(5) large breakers are being operated. It is concluded that more form and shape of local movable panel than the site of panel can be influenced on noise reduce.

  • The early investigators into the in-plane vibration of rings were Hoppe $Hoppe ^{1)}$ and $Love ^{2)}$. $Love ^{2)}$ Improved on Hoppe's theory by allowing for stretching of the ring. $Lamb ^{3)}$ investigated the statics of incomplete ring with various boundary conditions and the dynamics of an incomplete free-free ring of small curvature. Den $Hartog ^{4)}$ used the Rayleigh-Ritz method for finding the lowest natural frequency of circular arcs with simply supported or clamped ends and his work was extended by Volterra and $Morell ^{5)}$ for the vibrations of arches having center lines in the form of cycloids, catenaries or parabolas.(omitted)

  • This study aims at finding out the characteristics of the spatial organization for the private house and housing environment of an old village ‘Moo-Yee Ma-Yul’, Sun-san, KyungBuk, Korea. This village has sheltered since 5~600 years ago and is located geometrical on the buffer area between Southen and Northen area of South Korea, and is composed by two types of housing form; one is southen type and the other Northen. The housing was definded on scale with the ecinomical basement, and is changing rapidly on the quality of its environments such as the city-life housing style with the recently increasing income. The surveying time on the site was october 25th-30th and June 21st-22nd, 1996

  • This dissertation is focalized on examining research on the actual condition and problem in the exit-space-form of Multiplex Cinema and mutual relation of user and finding more efficient and reasonable project method through valuation of design elements which the user can feel. In result, 4 place which is newly opened after 1990's is analyzed in Seoul. It is researched that Many user feel inconvenience and discomfort when they recognize exit-space. In order to improve itthey want to feel at ease naturally with light-embeded sign and landscape space. The exit-space should be recognized that it is a part of cinema which have to be developed and planed for the inner part of cinema and security of user. Not death-space.

  • The purpose of this study was finding out the appropriate cleaning method for buried fabrics from old tombs focusing on the conservation of textiles. Cleaning effects and physical properties change depending on cleaning method have been analysed, The following results were obtained from this study : 1. Wet cleaning showed better effect on the cleaning of fabrics compared to solvent cleaning which meant more water-soluble soils existed than oily soils. 2. All the cleaning methods used did not cause any distorsion or shrinkage to the fabrics because fabrics had been stabilized for a long time 3. Addition of detergent to cleaning system decreased the friction of fiber during cleaning rocess so that the damage of fabrics could be minimized., 4. Ironing is an undesirable process because heat remarkably weakened fibers.

  • In the modern era, the world is facing unprecedented challenges in form of environmental pollution and international agencies are forcing scientists and materialists to look for green materials and structures to counter this problem. Composites based on renewable sources like plant based fibres, vegetable fibres are finding increasing use in interior components of automobile vehicles, aircraft, and building construction. In the present study, jute and flax fibre based composites were developed and tested for assessing their suitability for possible applications in interior cabin and parts of automobile and aerospace vehicles. Matrix system involves epoxy as resin and fibre weight fractions used were 45% and 55% respectively. Composites samples were prepared as per American society for testing and materials (ASTM) standard and were tested for individual fiber tensile strength, composite tensile strength, and flexural strength to analyse its behavior under various loading conditions. The results revealed that the Jute fibre composites possess enhanced mechanical properties over Flax fibre composites.

  • This paper deals with the inverse of tails of Hurwitz zeta function. More precisely, for any positive integer s ≥ 2 and 0 ≤ a < 1, we give an algorithm for finding a simple form of fs,a(n) such that $$\lim_{n{\rightarrow}{\infty}}\{\({\sum\limits_{k=n}^{\infty}}{\frac{1}{(k+a)^s}}\)^{-1}-f_{s,a}(n)\}=0$$. We show that fs,a(n) is a polynomial in n-a of order s-1. All coefficients of fs,a(n) are represented in terms of Bernoulli numbers.
