Busan has its unique character which differed from inland such as Seoul and Daegu Because Busan is located in coast district of Korea, it could be inferred that the climate change in Busan had been influenced by foreshore reclamation in the urbanization process. The purpose of this study is to investigate the relationship between reclamation of the foreshore and climate change by analysing the climate change over the past 70 years in three metropolitan cities. The conclusion from this study are as follows. 1) There was not a big difference among elements of climate change in three cities. 2) Annual mean minimum temperature in Seoul and Daegu had remarkably increased over the past 70 years. On the other hand, annual maximum temperature in Busan had a sudden rise in the only tome to reclaim the foreshore.

New cities and industrial complexes are being developed actively according to the government's policy. To determine the size of investment, number of power lines and substations for stable power supply to newly developed industrial complexes, the accurate estimation of power demand is necessary. "The standards for the estimation of power demands in newly developed residential and industrial complexes" established by KEPCO in 1991 have been used up to now. But the background for the estimation of power demands is weak and the accuracy has not been verified. Also, it has been passed above 10 years since their establishment and the social & economic situations have changed a lot, which requires an urgent revision. Through this survey and analysis of existing areas, new standards that will enable more accurate estimation of power demands in new cities and industrial complexes to be developed in the future are established by calculating the some kinds of power demand factors.

In order for effective heat island reduction policies to be proposed, this research made use of the land usage and land coverage and Temperature of cities, Coordinate axis data within 500 meters of nationwide automatic weather stations (478 points) in order to analyze the correlation of summertime temperatures through multiple regression analysis. This research also developed a model and empirically analyzed the urban heat island reduction effect of factors that affect regional temperatures. Heat islands cause environment deterioration and therefore can harm citizens' health, and also affects the city's metabolism process. Thus in order to restrain regional temperature rises the conclusion was drawn that consideration to increase forest areas on part of land usage planning is needed. Appropriate policy measures to regulate traffic related factors are also needed to restrain regional temperature rises. In order for future heat island reduction this research proposes a way to set up more effective policies and urban sustainability improvement strategies, and is significant in that it makes use of detailed data such as land usage and land coverage, Temperature of cities, Coordinate axis in analyses.

By the year 2050, the world population is set to increase to 9 billion people, of which 66% will be living in cities. It is argued that this will inevitably lead to further urban densification and soaring, inhumane and dense vertical environments. However, innovative and disruptive technologies impacting all realms of life means that we will also live, work, play, learn and make in novel ways, the beginnings of which are already becoming evident. These present opportunities for reimagining city environments, and in particular tall buildings, with a focus on reducing redundancies and re-appropriating existing buildings, creating novel hybrid environments, incorporating green and social democratic spaces, and integrating multiple modes of transport. This paper examines how vertical cities may perhaps be dense, resource efficient, and yet humane, presenting three possible scenarios for Singapore's context, which are, however, common to many Asian high-density urban environments. The scenarios presented are the outcome of Final-Year Thesis Projects undertaken by final-year architecture students at the National University of Singapore (NUS) in 2017.

The study of young people's attitudes towards appearance management has special significance for understanding young people's living, thought and attitudes. It was handed out 600 questionnaires in the three cities and look 573 questionnaires back, out of which 552 were used as the basic material for the analysis. These 522 questionnaires included 178 in Beijing, 200 in Shanghai, 175 in Dalian. 154 questions in four aspects were raised in the questionnaires. The purpose of this study were to identify the Chinese generation' lifestyle and fashion attitudes. Questionnaires developed by researcher were distributed and collected from 552 chinese new generation of the three cities(178 in Beijing, 200 in Shanghai, 175 in Dalian). 1) Life attitudes of new generation men and women in China were classified into five factors, which were extravagant pleasure-seeking, sports-oriented, marriage-oriented, appearance-oriented and study-oriented attitudes. 2) Fashion attitudes of new generation men and women in China were classified into eight factors, which were fashion attitude of being conscious of others, others-dependent fashion attitude, rational fashion attitude, brand-pursuing fashion attitude, active appearance management fashion attitude, unique fashion attitude, fashion attitude of being conscious of sex role and individuality-oriented fashion attitude.

Background: Panax notoginseng is a highly valued medicine and functional food, whose quality is considered to be influenced by the size, botanical parts, and growth environments. Methods: In this study, a HPLC method integrating fingerprinting and determination of multiconstituents by single reference standard was established and adopted to investigate the chemical profiles and active constituent contents of 215 notoginseng samples with different sizes, from different botanical parts and geographical regions. Results: Chemical differences among main root, branch root, and rotten root were not distinct, while rhizome and fibrous root could be discriminated from other parts. The notoginseng samples from Wenshan Autonomous Prefecture and cities nearby were similar, whereas samples from cities far away were not. The contents of major active constituents in main root did not correlate with the market price. Conclusion: This study provided comprehensive chemical evidence for the rational usage of different parts, sizes, and growth regions of notoginseng in practice.

Together with the concern about the indoor all quality as sick house syndrome, the Ministry of Environment announced "Indoor Air Quality Control Law for the Multi Purpose Facility," which made the interests to be focused in the urgent understanding of current condition and preparation of measures about the indoor air pollution. In Dec 2005, the law was revised to obligatorily notify the amount of Formaldehyde and Volatile Organic Compounds in the case of newly constructed apartments with more than 100 houses. School also have its own indoor air quality guideline, Indoor air quality in school is very important because, children who very weak to indoor pollutants reside long time in there. The purpose of this paper is to survey indoor air qualify in school by field measurement. Field measurements were performed in 11 schools which were selected from 3 major cities(Incheon, Dae-jeon, chuncheon) in korea, during July, 2004. Totally concentration of Indoor pollutants were determined in 27 classroom. Target air pollutants were TVOC, formaldehyde, dust, CO, CO2 and NO2. For the result of this investigation, Indoor air quality in classroom was very poor and it was found that some pollutants (TVOC, float bacteria) exceed the guideline.

Purpose. The purpose of this study was to determine the relationship between peer and parental factors and smoking behavior of adolescents in urban cities and to investigate whether there are gender differences. Methods. A stratified and random cluster sampling design was used to obtain a cross-sectional sample of high school students in two urban cities. The sample consisted of 512 Korean adolescents (256 boys and 256 girls) aged 15 to 18 (mean age 16.7$\pm$.58). Self-reported questionnaire consisted of adolescent smoking behavior, peer smoking and alcohol use, parental smoking and alcohol use, father-mother-peer relationships and perceived social support from peers and parents. Multiple logistic regression analysis was used to examine the hypothesized model. Results. The findings showed that peer and parental factors accounted for $30.3\%$ of the variance in adolescent smoking and peer smoking was most strongly associated with adolescent smoking behavior (OR = 10.18). In addition, peer smoking (OR = 4.71), peer alcohol use (OR = 4.21), and peer relationships (OR = 1.03) were significantly associated with boys' smoking behavior. In girls, peer smoking (OR = 26.50) and parent smoking (OR = 5.48) were significantly associated with smoking behavior. Conclusions. Consistent with previous findings, peer smoking is a significant factor on adolescent smoking. Specifically, boys would be more influenced from peers than girls. Therefore, smoking prevention programs for adolescents might be focused on the social context such as, resisting to peer pressure and enhancing the self-efficacy to control.

If we take account of the 'Architectural Tradition' which aims a construction of better environment, we can see that this tradition has ended historically toward Utopia. And the concrete concepts of utopia mainly started on the Renaissance periods. The Utopias were described well in the literatures which contained particularly three representative utopian books in Renaissance period. The one was the most famous novel by Sir Thomas More and the other were by Tommaso Campanella and by Francis Bacon. These novels expressed ideal commonwealths in which inhabitants exist under perfect conditions, ideally perfect places or state of things. The plans of utopia are complete projects of image, its goal is an political, social and economical improvement according to the eras. Their utopias mostly had characteristics as follows; their shape of islands were almost circle, their shape of cities were rectangularity or circle and attached importance to geometrical compositions, their structure of cities were self-sufficiency in closed spaces and their architectural characteristics were uniformity, simplicity and non-ornament. And these architectural characteristics are urban and architectural traditions in communist countries. Also their utopian novels had not much explanations to daily lives of people like as birth, death, relative, mental conflict or authority, money, art. So their utopian novels were not practical and had inappropriate aspects.

Korea has been striving for the development of the nation in various aspects. It will also have to make an effort for its continued development in the future. The problems of low-income groups that occur in those processes cannot be simply ignored now. It is needed to provide an equal opportunity to low-income groups so that they can be part of the society. The cycle of economic problem should be disconnected through this process. Farm-Housing is one of the solutions to this problem. Its purposes are not only to provide residence in the complex, but to gain income through various activities, such as production, distribution and consumption, and solve part of the economic problems of the people living in the Farm-Housing. To sell the products of Farm-Housing, the neighboring cities need to be designated as a hinterland. For this reason, Farm-Housing needs to be located in the suburban area of large cities. However, the current laws and policies make it difficult to construct Farm-Housing in suburban areas. Presenting plans to solve such problem is the purpose of this paper.
