The purposes of this study were to research 1) the background of origination, 2) the process of development and 3) the influences to modern clothing culture of American sportswear. The most Influential sportswear designers in America from beginning period to present : such as Claire McCardell, Calvin Klein, Ralph Lauren and Donna Karan were selected to study their life and achievements in the world sportswear market. The Results were as follows : 1) World War I & II have caused the greatest changes to modern history America became the center of world economy, society and culture. Politically, they have influenced democracy world-wide and raised the social status of women. The free American women enjoyed sports, Jazz drinking and car-driving. The advanced technology have accelerated mechanization and mass-production to the fashion industrv. 2) The above historical backgrounds have caused to change women's clothing to casual, practical and simple form. Dorothy Shaver at Lord & Taylor began promoting American designers who created the original American spirit. Claire McCardell created the seperated American sportswear to become world-wide fashion. Calvin Klein and Ralph Lauren, the sportswear designers who have the unique American feeling have come to have riches and fames equal to the top designers in Paris. 3) The American sportswear and fashion industry influenced Paris Mode, the traditional Haute Couture to open Pret-a-porter-a-porter. The concept of seperated coordination in American sportswear have promoted the advanced marketing techniques and merchandising systems to modern ready-to-wear industry. Fashion in 1980s have increased the mutual interdepedence between the American sportswear industry and the creative Paris Mode. And then, the fashion world in 1990s and 21C will be changed and developed on the basis of American sportswear mechanism.

Based on a concept of Nietzschean nihilism, this study aimed at interpreting the nihilism in arts and its expressions, also analyzing the modern fashion collection from the same angle. The research was centered on arts after 1980, when post-modern formal destruction expanded in earnest and on the fashion collection after the 20th century, easily accessible to data. Particularly, it set 1994 nihilism collection by Alexander McQueen, a representative nihilist fashion designer as a starting point. Nietzsche mentioned that true arts may be achieved when Apollonian characteristics including a bodily sensory system and an idealization process and Dionysian characteristics including every human feeling are integrated. Besides, he emphasized the importance of an artist being represented as an image of ${\ddot{U}}bermensch$. The ${\ddot{U}}bermensch$ image, reflected in arts and artistic nihilism, represents themes of violence/death, realistic/unrealistic expressions, human body/inhuman aversion materials and the transmutation of a form. Fashion collection expressions, owing to the special characteristic of the show form unlike other arts, were segmented as a realistic ${\ddot{U}}bermensch$ image using a model in a theme, expression, material and form. The theme of violence/death was divided into the death of human and a society. Human life/death was expressed as destruction of human weakness and self-identity, sexual objectification and violence, and social death as destruction and conflict of a class, nation, culture and nature. As for the expression, it was divided into the realistic expression of the primitive/natural and directing of an unrealistic atmosphere using a show.

The currently accepted model of membrane structure proposes a dynamic, asymmetric lipid matrix of phospholipids and cholesterol with globular proteins embedded across the membrane to various degrees. Most phospholipids are in the bilayer arrangement and also closely associated with integral membrane proteins or loosely associated with peripheral proteins. Biological functions of membrane, such as membrane-bound enzyme functions and transport systems, are influenced by the membrane physical properties, which are determined by fatty acid composition of phospholipids, polar head group composition and membrane cholesterol content. Polar and non-polar region of the phospholipid molecule can interact, with changes in the conformation of a membrane-associated protein altering either its catalytic activity or the protein's interaction with other membrane proteins. Mammalian dietary studies attempted to change the lipid composition of a few cell membranes have shown comparisons, using essential fatty acid-deficient diets. In recent years, Clandinin and a few other workers have pioneered the study proving the influence of dietary fat fed in a nutritionally complete diet on composition of phospholipid classes of cell membrane. Modulation caused by diet fat was rapid and reversible in phospholipid fatty acyl composition of membranes of cardiac mitochondria, liver cell, brain synaptosome and lymphocytes. These changes were at the same time, accompanied by variety of membrane associated functions controlled by membrane-bound enzymes, tranporter and receptor proteins. The findings suggest the basic concept of the necessity of dietary fatty acid balance if consistency of optimal membrane structural lipid composition is to be maintained, as well as the overall inadequacy of describing the nutritional-biochemical quality of a dietary fat solely by its content of linoleic acid. Furthermore, they give light on the possible application to clinical and preventive medicine.

This study intended to present a new direction of differentiated and innovative furniture design for small living space overcoming the uniformity of conventional small living. In order to achieve these goals, a new piece of furniture with multi functions useful for such small space has been designed and explained in this study. This new type multi-functional furniture can be utilized as kitchen, dining table, home bar or office stand depending on the user's necessity. In particular, it provides more adaptability to changing life and spatial availabilities for small living space in terms of space division, separation and fusion features. Based on the needs of small living space brought by social changes, the conventional concept of small living space, which divides space by partitions or walls, should be changed into flexible perception of space. Also, this research proposed the features of furniture design for functional shifts in terms of its functional, structural, and systematical aspects. In this respect, space can be regarded as a variable place and the image of space can be differently appreciated by means of shift, functional transition and mobility. That is, small living space can be perceived as kitchen, living space or working space at the same time. In conclusion, the versatile use of limited space can be a solution to the issues related to small living space; the convertible and movable furniture called F4 Island presented in this study can transform such spatially limited space into a space with multiple functions to meet the requirements of its residents.

The purposes of this study are to establish a theoretical concept of nudism from sociocultural context, to examine its formative characteristics, to analyze the cultural meaning of nudism style showing in the 2000's fashion world, and to analyze and examine its aesthetic qualities. The way of a study was based on analysis and review on philosophy, aesthetics, sociology, popular culture and various documents at home and abroad and previous study and research materials about art and clothes for theoretical study. Also, we carried out a case study by analyzing photo data from fashion books, magazines and internet websites, considering the body and dress as visual objects. The summary and conclusions of this study are as follows: 1. Nudism of the sociocultural context was divided into change of understanding of the body and liberation of the body; naturalism; resistant culture; psychoanalysis context. 2. The formative characteristics of nudism style in fashion are classified in Exposure, Transparency and Body Conscious. 3. The cultural meaning of nudism style expressed in the 2000's fashion are sexual opening, surfeit of mass media, pursuit of naturalism, lookism, and individualism. 4. Nudism style expressed in 2000's fashion is drawn as three aesthetic qualities: Eroticism, Primitivism and Futurism. First, Eroticism of nudism style fashion which seeks for sexual stimulus is classified in Sensualism, Provocation and Innocence. Second, Primitivism of nudism style fashion which tends towards naturalism objecting to mechanic and digital civilization and hoping for return to the origin is classified in Primitivism, Naturalism and Sensualism as per aesthetics qualities. Futurism which is the nudism style presenting futuristic expression through using a new material is analyzed as High Technology, Cyber Sexism and functional Future.

In this paper, we have developed a Fama - French five factor model (FF5 model) from Fama & French (2015) by using concept of time-varying coefficient. For a data set, we have used monthly data form Kenneth R. French home page, it include Japan portfolios (classified by using size and book-to-market) and 5 factors from July 1990 to April 2020. The first analysis, we used Augmented Dickey-Fuller test (ADF test) for the stationary test, from the result, all Japan portfolios and 5 factors are stationary. Next analysis, we estimated a coefficient of Fama - French five factor model by using a generalized additive model with a thin-plate spline to create the time-varying coefficient Fama - French five factor model (TV-FF5 model). The benefit of this study is TV-FF5 model which can capture a different effect at different times of 5 factors but the traditional FF5 model can't do it. From the result, we can show a time-varying coefficient in all factors and in all portfolios, for time-varying coefficients of Rm-Rf, SMB, and HML are significant for all Japan portfolios, time-varying coefficients of RMW are positively significant for SM, and SH portfolio and time-varying coefficients of CMA are significant for SM, SH, and BM portfolio.

Ubiquitous mobile computing is becoming easier and more attractive in this ambient technological Internet world. However, some portable devices such as Personal Digital Assistant (PDAs) and smart phones are still encountering inherent constraints of limited storages and computing resources. To alleviate this problem, we develop a cost-effective protocol, iATA to transfer ATA commands and data over TCP/IP network between mobile appliances and stationary servers. It provides mobile users a virtual storage platform which is physically resided at remote home or office. As communications are made through insecure Internet connections, security risks of adopting this service become a concern. There are many reported cases in the history where attackers masquerade as legitimate users, illegally access to network-based applications or systems by breaking through the poor authentication gates. In this paper, we propose a mutual authentication and secure session termination scheme as the first and last defense steps to combat identity thief and fraud threat in particular for iATA services. Random validation factors, large prime numbers, current timestamps, one-way hash functions and one-time session key are deployed accordingly in the scheme. Moreover, we employ the concept of hard factorization problem (HFP) in the termination phase to against fraud termination requests. Theoretical security analysis discussed in later section indicates the scheme supports mutual authentication and is robust against several attacks such as verifiers' impersonation, replay attack, denial-of-services (DoS) attack and so on.

The purpose of this study is planning a representative model of a modernized school with rearrangement of existing two primary schools(Nammyun and Namjin) and a middle school(Seonam) in Nammyun distric. Nammyun district, which is adjacent to Tae-an national ocean park, is the Place where gas a natural advantage. However, in the result of the rural exodus follwed by industrialization, the population in this province are decreased rapidly and it still be on the process of the rural exodus. Hence, the total number of students, each school is under 100 at the moment and the number will be less in the future. Under this consequences, the rearrangement of these school is inevitable. For the new modernized school plan Narnmyun district, estimate the scale of school on the basis of decreased number of students, the analysis the 7th education plan and the questionnaire and face-to-face interview investigation, which is a resident-orented investigation, were carried out preferentially. The major research contents are as follows; o Expansion of schools facility and space for operating the 7th education plan(classified level schools level and subject-based class school plan) o Over-all improvement of educational environment to take all-out advantages of school, social and home education. o The school which can take a part of an educational center of a rural community in schools off-time-after school and summer and winter vocation. o The school which is related to the local cultural, sports and entertainment utility, On the basis of this research, the basic concept and purpose of a new school model model plan in Nammyun will be established and the new school plan represented for the result of this research.

If human beings could make friends with nature, it would be a truly wellbeing. This project has selected the design concept under the supposition that human beings and the nature become friends. This residential house, which is consisted of one ground floor and two underground floors, is confronting the mountains that surround the residential complex. Residents can enjoy viewing the mountains from the living room. The garden is created by using this given environment in maximum. The walls are made up with rocks, and a small pond is formed with water from the mountain, presenting another attractive sight. Through the connection rather than the break between mountain and garden, living room and garden, and again garden and mountain, the dialogue with nature was attempted. The water of the pond in the garden flows down along the walls and creates another water space at the gate area of the house. Passing through the entrance, there are a living room, a kitchen, a bedroom for spouses, a common bathroom, and a library on the ground floor. On the second floor, there are two rooms, a bathroom, and a mini living room. The platform of living room on the 1st floor is lowered to produce the comfortable living room with the hearth. From the view of living room, the garden with full feeling of nature can give a good emotional rest for modem people who want the mental relaxation. The marble stones are used as its material to present rich texture and sophisticated image presentation. The hearth in the living room is harmonized with high-tech electronic home appliances and surrounding accessories. On the kitchen, the high-glossy materials are used to express the external appearance neatly and the depository function is more improved for housewives.
