A standpoint art's style, present-day Western dress was establishing a systematic, theoritical value in sphere of fine art's meaning & it's expression on the modern fashion. For this reason, I selected Impressionism (a broad senes: be included Impressionism, Neo-Impressionism, Post-Impressionism) that was designated 'the revolution of color'. In the previous paper, 1 already discussed about the modern fashion under the influence of the color of Impressionism, from this study, Neo-Impressionism's techniques & it's influence on the modern fashion was investigated. The Impressionists had purposely used uneven brushwork & a vivid palette to transmit the intensity & immediacy of nature, whereas the Neo-Impressionists utilized methodically applied dots, a technique commonly described as Pointillism, to achieve their rationalist goal of eliminating the fugitive & the casual in order to seize a more fundamental reality. Of all them, Seurat had already become interested in the posible analogies between science, music & psychology on the on hand & art on the other, and scientist's books & articles offered a wealth of theoretical support. 1'articulary, it was corroborated that effects of sadness, calm, or happiness could be achieved through manipulation of color & design. The conclusions are as follow: 1. Through the modern fashion, a space between pattern & pattern was reflected unstable balances & harmonies, that, Neo-Impressionist emphasized the distinction between outdoor & subject, between elaborately clothed & nude figures, corresponded to modern fashion's pattern. 2. The modern fashion was presented a small border or band within the pattern itself which colors complemented those of the adjacent pictorial surface and mediated between the painted image & its enclosure.

The purpose of this study is to investigate the formative beauty, changes in fashion and aesthetical sense that can be seen in the bias drapings of Madeleine Vionnet and her influences on modern fashion since she used draping as a new fashion means to represent the new feminine images which modernism of the early 20th century and social changes from the two great World War's generated, and to provide proper data to encourage designers' creativity that is wanting in the circle of Korea fashion. Bias draping led women to respect worship their body from the heart with seductive modernism enriching the material's texture to the utmost through geometrical patterns of triangle, quartered plane and quardrants and simple cylindrical cuts and with an attribute adapting itself to the wearer's body. Bias draped wear consisted of light and transparent materials and overall surface decoration revealed women's movements and sought the extension of environmental movements and demonstrated its eroticism. On the other hand, biased daywear gained anonymity through cutting true to body line and psychological protective quality as of cape, and this went well with the independent femininity accepting difference as well as pursuing revolution from the inside. The great inflation and the 2nd World War gave birth to escape from reality like surrealistic artistic tendencies and Hollywood films and increased romanticism. Bias draping once underwent unpopularity except in expensive clothes due to knit wear boom and the utilization of new elastic materials, however, it began to receive lights again from pluralization waves and retro tendencies and to be introduced in many designers' collections. A young genius of England, John Galliano improved functions of Haute Couture through creation of new styles and fantastic shows to promote profits in the fashion markets. Bias draping fitted in human body line provides us comfort and aesthetic qualities through careful choice of material and elegance by delicate cutting.

Since the Industrial Revolution has caused global change by using of a fossil fuel, a reckless and growth-oriented development. A global mean temperature since 19th century has climbed up 0.4~$0.8^{\circ}C$. Our country, afterwards, global warming has increased the temperature every season. After The Kyoto Protocol regarding a greenhouse gas reduction goal took effect, be situations that decrease of greenhouse gas was acutely required. Therefore, interest of utilization of the new & renewable energy is increasing everyday. In advanced research, we shows that at first divided a country to nine range by natural geography, and second executed Meteorological data analysis of recent 30 years considering level of significance by nine range. The results of advanced research are that the similarities are low because there are the regions that temperature deviation of the similar climate regions is large in winter season, and there are not characteristics of clear discrimination of temperature. This study shows that at first divided a country to six range by temperature range, and second executed Meteorological data analysis of recent 30 years considering level of significance by six range. The results of this study are that in heating load calculation of building, periodic temperature data management is required because facility capacity and cost are affected greatly by outdoor temperature, and temperature by climate range needs consideration of pertinent area. Ground temperature was assumed of the weather in region, the ground and soil. Lastly, we were able to know that establishment of climate region by temperature range can be useful policy making and plans of design of the horticultural facilities and architectures.

Tough Korean architecture and urban environment has been developed for almost 100 years, it still remains various kinds of problems. Many attempts was carried out by every new plan to reduce the problems, it result in requiring more investment than before. It means all the investment for the development has been inefficient and immature to protect economic problems compared with the developed country. For the reason of economic problems it must be studied in historical cases which influenced the economic impacts, before the proposal of index with the economic theory. Searching typical architecture or urban development that brought about economic impacts can be classified into 3 cases. First case is the impact that caused the economic growth, increase, boom like the Westminster & others and the american architectures after the economic crisis. Second case is the impacts that was the origin of decline, shrink in economic as the Palace of Versailles, the skyscrape buildings in america before the economic crisis. Third case is the impact that was the both role of increase and decline in economic as the modern architecture in industrial revolution which led to the national economic growth and the gap between the rich and the poor, and as the american architecture that was the root of crisis and the revival in economic. From the case study, it is clear that architecture has relation with economics in various factors as mass production, labour, and another industries all over the history & the world. Now, architecture strongly needed not only to raise functional, cultural effect and value, but to predict and control the economic impacts with theory from further research of historical cases to policy and practise.

한국사회는 위험과 불신이라는 측면에서 복합 위험사회다 농경사회의 전근대적, 산업사회의 근대적, 정보화사회의 후근대적 위험과 재난이 현재라는 시간대에 동시에 존재하기 때문이다. 경제적 부를 획득하고자 하는 끝없는 과학기술의 발달은 동시에 위험사회를 도래한다는 울리히 벡의 지적은 지금 우리에게 있어서 많은 시사점을 제공해주고 있다. 본 논문에서는 이미 20세기 후반에 새로운 근대화의 진전에 따른 위험사회의 도래를 지적하고 그 위험사회를 극복하기 위한 "성찰적 근대화(reflexive modernization)"를 언급한 '울리히 벡'의 이론을 새롭게 살펴보고자 하였다. 왜냐하면 성찰적 근대화는 인간중심적인 관점에서 우리의 잘못된 과거를 반추하고 바람직한 미래를 설계해 주는 방향타가 될 수 있기 때문이다. 이러한 의미에서 성찰적 근대화를 주장한 울리히 벡의 재해석을 통해 위험사회 극복을 위한 방안을 제시하는 것은 중요하다. 4차 산업혁명이 가져올 미래의 새로운 위험을 극복하기 위해서 안전(security & safety)을 전공하고 연구하는 우리는 정부의 안전정책과 국민들의 안전의식에 대한 방향을 제시하여야 하기 때문이다.

Recently, the advancement of information and communication technology(ICT) is expanding the connectivity through Internet of Things(IoT), and the media of connection is also expanding from wire/cable transmission to broadband wireless communication, which has significantly improved mobility. This hyperconnectivity has become a key element of the fourth industrial revolution, whereas the supervisory control network of purification plants in korea is operated as a communication network separated from the outside, thereby lagging in terms of connectivity. This is considered the best way to ensure security, and thus there is hardly any consideration of establishing alternatives to operate an efficient and stable communication network. Moreover, security for management of a commercialized communication network and network management solution may be accompanied by immense costs, making it more difficult to make new attempts. Therefore, to improve the conditions for the current supervisory control network of purification plants, this study developed a industrial security L2 switch that supports modbus TCP(Transmission Control Protocol) communication and encryption function of the transmission section. As a result, the communication security performance improved significantly, and the cost for implementing the network management system using Historical Trend and information of HMI(Human Machine Interface) could be reduced by approximately KRW 200 million. The results of this study may be applied to systems for gas, electricity and social safety nets that are infrastructure communication networks that are similar to purification plants.
