The Chinese economic growth rate has been much higher than many countries of the world for many years now. Nowadays, China is experiencing significant economic transformation and structural adjustment. Its speed of development is slowing, and housing and commodity prices are slowly rising. Consequently, a series of economic and social problems have come into being. Under these circumstances, how satisfied are Chinese people on the seven aspects of daily living such as Housing Situation, Household Income, Health, Family Life, Food, Human Relations and Job? The Media and Public Opinion Research Center of Fudan University (FMORC) conducted a phone survey of 606 people living in Beijing, the capital and political and cultural center of China, and Shanghai, the Chinese economic center. The survey results show that the overall satisfaction of Chinese people with their daily life is high. The levels of Family Life and Human Relations are on the top, those of Food, Health and Jobs are listed from the third to the fifth, and satisfaction levels of their Housing Situation and Household Income are on the bottom. The satisfaction levels of males with their Family Life and Health are higher than those of females. Age has a significantly negative correlation with satisfaction with personal health. Monthly income has positive relationships with four aspects of daily life - house income, job, house situation, and family life. Owning a house in cities is another important factor that influences satisfaction with the house situation, house income, food, and family life. Shanghai residents also show higher satisfaction with their health than Beijing residents.

Purpose - With the economic development in China, the lifestyle of Chinese customers has changed dramatically. Chinese customers are more likely to have coffee in a shop with the ability to make them happy than those with high quality coffee in a nice physical environment. Happiness becomes a critical driver of customers' intention to purchase a cup of coffee in a specific coffee shop again and again. As a result, happiness becomes an important factor for managers to make strategies for attracting customers. Although managers and scholars pay more attention to emphasize the importance of happiness in customers' consumption, little research has been conducted to investigate the relationship between happiness and coffee shop's continuous usage intention in the Chinese coffee industry. Research design, data, and methodology - A research model is made to explain the impact of happiness on customer's behavior. To understand the influence of happiness better, we consider two dimensions of happiness which are subjective well-being and psychological well-being. In order to confirm the relationships of the variables in the research model, the online survey is constructed in China. Customers who have experienced the services in a coffee shop are asked to do the questionnaire. With 453 reliable questionnaires, structural equation modeling is used to analyze the causal relationships of the coffee quality, physical environment, subjective well-being, psychological well-being, and continuous usage intention. Results - Results indicate that coffee quality and physical environment are not the direct factors that influence customers' continuous usage intention. However, good coffee quality and physical environment are the significant predictors of Chinese customers' happiness associated with subjective well-being and psychological well-being, which in turn affects customers' continuous usage intention. Conclusions - In this study, it is proposed that coffee quality and physical environment may be the key factors influencing customers' happiness. Happiness, including subjective well-being and psychological well-being matters in decision making process. More importantly, happiness increases the continuous usage intention when the coffee shop can serve customers with higher quality coffee at a good atmospheric place. Managers should consider happiness as an important factor in making marketing strategies to compete in this industry.

In 2000s, the interest of ROHAS has been increased and the environmental problem has begun to be discussed as the environmental and global value, not the individual perspective. And the standard of value for eco-friendly awareness has been expanded to the economic category. The trend of eco-friendly fabric can be divided into 3 periods depending on the property. The period for natural fabric with visual effects(2002~2004) can be summarized as the creation of natural shape using the natural image, the interaction of cotton and the technology from the visual perspective. In the period of functional conjunction with eco-friendliness and technology(2005~2008), the eco-friendly awareness through the conjunction of technology and nature and the re-cycling, and the responsibility to the environment had been increased. In the period of sustainable development for nature and environment(2009~2011), it showed the conjunction with nature and the integration with technology and eco-friendly issues. Therefore, the characteristic of eco-friendly trend in fabric since 2000 can be said; firstly, the high-quality fabric has been developed with technological development for the functional progress. Secondly, the ethical creativity has been displayed with the development and utilization of eco-friendly recycling materials. Thirdly, the materials reflected with eco-friendly issues have emerged.

유비쿼터스 에코시티(U-Eco City)는 첨단 IT기술을 도시공간과 접목시킨 유비쿼터스 도시(U-City)와 지속가능한 생태도시(Eco-City)의 개념이 융 복합된 새로운 도시패러다임이다. 하지만 국내외적으로 처음 시도되고 있기 때문에 U-Eco City에 대한 개발목표, 계획안, 실시설계안, 기술 및 서비스 요소 등이 혼재하여 명확히 정립되지 않고 있다. 무엇보다도 U-Eco City의 무엇을 어떻게 평가해야 하는가에 대한 구체적인 논의가 부족한 실정이다. 이에 본 연구는 U-Eco City의 도시 질과 환경을 평가하기 위한 지표체계를 제시하고자 하였다. 이에 따른 연구결과는 다음과 같이 정리할 수 있다. 첫째, 국내외에서 논의가 미흡했던 U-Eco City에 대한 개념을 정립하여 지속가능한 도시의 질을 달성하기 위한 개념적 틀을 제시하였다. 본 연구에서 제시된 U-Eco City의 개념은 기존도시의 경제적 발전과 성장위주 개발방식에서 도시의 질적 환경과 지속성 차원의 복합적인 영향을 종합적으로 파악해야 한다는 점을 제시하고 있다. 이 같은 연구 성과는 향후 도시개발에서 관리체계의 근거로 활용될 수 있다. 둘째, 개발된 평가체계는 의식조사를 통해 평가지표로서의 완성도를 높였다. 전문가 및 이해관계자를 대상으로 설문조사한 결과, 도시의 질적 측면은 안전성이 상대적으로 중요한 요소로 도출되었다. 도시의 지속성 측면에서는 사회, 환경, 경제 모두 중요도가 유사하게 나타났으나 그 중에서 환경요소가 높게 나타났다. 이는 과거 도시개발시 우선요소로 안전성과 경제성을 둔 반면 현대에 들어 환경문제의 심각성을 인식하고 '저탄소 녹색성장'과 같은 각종 정책이 영향을 미친 것으로 해석된다. 마지막으로 평가체계를 기반으로 사례대상지역을 선정하였으며 실시설계안을 중심으로 평가를 실시하였다. 평가결과, '안전성'과 '경제성' 부문이 높게 평가되었으며, 이는 의식조사에서는 환경적 지속성이 중요시 된 반면 설계안에서는 아직까지 경제성장 위주의 개발계획이 우선적으로 이루어진 것을 보여준다. 따라서 향후 도시개발시 환경적 측면의 보완이 필요하며, 경제성장과 환경적 지속성간의 연계방안도 제시되어야 할 것이다.

During the past decades, dramatic technology changes affected the life of billions of people around the globe. Although these changes resulted to economic benefits, mostly for the developed countries, the undiscerning development also resulted to many side effects, such as environment pollution, scarce natural resources, global warming, and an increase of the gap between "those who have" and "those who have not", among others. Also, since these developments were based on high technologies, they were not suitable for 90% of the underdeveloped countries. In this review, the possible ways of increasing the quality of life in underdeveloped countries are described, by providing adaptive solutions using appropriate technologies. Some successful applications of appropriate and intermediate technology are introduced, and the need for a new undergraduate education course of engineering design based on appropriate technology is proposed for Korea.
