This study aims to describe actual condition of residents' involvement of Sk$\"{a}$rk$\"{a}$ll ecovillage in Sweden by in-depth interviews with five residents. This study, hopefully, could contribute to offer useful information for forming ecovillage, as well as awakening about ecovillage movement to the public in Korea. The interviews were fulfilled during spring of 2010 in G$\"{o}$teborg and Sk$\"{a}$rk$\"{a}$ll ecovillage in Sweden. The results are as follows: 1) In terms of overall residents' involvement by self-evaluation everybody agrees with that residents' involvement was quite excellent during forming stage of the village, while it has been notably decreased now in running stage. It reveals there is a gap between ideology and reality. 2) Concerning decision making method, they use majority decision instead of consensus, since only 9 households of 20 are residing there all year around, it is hardly possible to assemble all the residents in the meeting. In Accordance with problematic conflicts in the village recently, development of socialization with others and education of communication skill for residents probably could be helpful to resolve conflicts among residents in long term. 3) In terms of evaluation of ecovillage movement in Sk$\"{a}$rk$\"{a}$ll ecovillage, it is the fact that many residents live less self-sufficiently, more energy consumed than the ideology pursuits. Also, they live with close connections with conventional society. Nevertheless, the efforts they are willing to practice 3R principles (Recycle, Reuse, Reduction) have to be highly respected, if we consider its educational influence to environmental movement for the conventional society.

In recent years, the relationships and inter-dependencies between the countries in East Asia have deepened, and the vision for regional cohesion such as the East Asian Community have been gradually elaborated. A Grand Design for Northeast Asia is one of these comprehensive visions that aim to improve and develop international infrastructure through cooperation in the field of transportation, energy, environment, and information technology. This study paid attention to the possibility for a system for regional cohesion and cooperation in spatial development in East Asia, and analyzed the roles of the ESDP according to the requirements of the East Asian situation. As a result, it was understood that while the development of infrastructure is a main stream in the case of the regional cohesion in East Asia, the cooperative visions for the conservation of natural and cultural heritage, which are being positioned as an important policy in the EU, have not been seen. It is a very important subject to promote the policy cohesion/cooperation on the conservation and management of natural/cultural heritage and the development of tourism infrastructure for the sustainable development of East Asia, considering the trends in the growth of the interchange population and tourism market in East Asia. It was discussed that the role of research networks like the International Landscape Architectural Symposium of Korea, China and Japan is becoming important in supporting this policy cohesion and in grasping the present conditions and trends of the spatial development of these counties.

Since the accomplishment of industrialization and mechanization, human and the nature have gone farther their own way. Human depending on technology have been increasingly expanding and developing their artificial space and as times go by in such a way, estrangement between the human and nature has resulted in dissatisfaction of human's instinctual desire and devastation of human's living. People, to deal with such challenge, begins taking a look at the nature. In introducing the nature into the modern architecture, a physical natural element is often directly taken into or the shape that could be inferred from the nature is taken. The study was intended to identify the characteristics of the pattern introducing the nature into the modern architecture, as mentioned in the former case, which is summarized as follows, Introduction of the nature contains a variety of functions in the space and it creates the new space by integrating the internal and external space which becomes boundaryless integrated space. The boundary in the building tends to be getting more ambiguous, while the space accommodating the nature serves the interface, playing a role of intermediator for both the internal and external space. It functions the open public place that helps build the natural community among the users but taking the nature into the inner space, and it is used to attempt to change the interior of the building or for ventilation lighting or energy-saving purpose. The spatial meaning was found to have varied depending on pattern of the nature introduced. Such conclusions mentioned hereon is expected to help forecast and understand the forthcoming space accommodating the nature when reviewing the pattern of introducing the nature appeared In modern architecture.

BACKGROUND/OBJECTIVES: Sustainable practices in foodservice organizations including commercial and noncommercial ones are critical to ensure the protection of the environment for the future. With the rapid growth of the foodservice industry, wiser usage of input sources such as food, utilities, and single use packaging should be reconsidered for future generations. Therefore, this study aims to investigate the customer's perceptions on sustainable practices and to identify the relationship among sustainable practices, social contribution and purchase intention. SUBJECTS/METHODS: The study was conducted using content analyses by reviewing articles on sustainable food service practices published domestically and abroad. Thereafter, data were collected with a face-to-face survey using a questionnaire and analyzed with factor analyses and multiple regressions. RESULTS: Sustainable practices classified with factor analysis consisted of 6 dimensions of green food material procurement, sustainable food preparation, green packaging, preservation of energy, waste management, and public relations on green activity, with a total of 25 green activities in foodservice operations. Consumers were not very familiar with the green activities implemented in the foodservice unit, with the lowest awareness of "green food material procurement (2.46 out of 5 points)", and the highest awareness of "green packaging (3.74)" and "waste management (3.28). The factors influencing the perception of social contribution by foodservice organizations among 6 sustainable practice dimensions were found to be public relations on green activity (${\beta}=0.154$), waste management (${\beta}=0.204$) and sustainable food preparation (${\beta}=0.183$). Green packaging (${\beta}=0.107$) and the social contribution of the foodservice organization (${\beta}=0.761$) had strong relationships with the image of the organization. The purchase intentions of customers was affected only by the foodservice image (${\beta}=0.775$). CONCLUSIONS: The results of this study suggest that sustainable practices by foodservice organization present a good image to customers and increase the awareness of valuable contributions that benefit the customer as well as the community.

The purpose of this essay is three-fold: to trace the genealogy of the Korean musical, which ever since its inception in the 1960s has been seeking to modernize Korean theater with Broadway as a constant role model; to investigate how the national and the global conflict and are conflated in the form of the Korean musical in the process of its (dis)identification with Broadway; and to examine how its intercultural translations reveal and reflect the dilemma and ambivalence posed by globalization in our era. Drawing on Richard Dyer's signature article Entertainment and Utopia, I analyze how the Korean musical manifests and conduits competing utopian impulses of Korean/Global audiences. I also attempt to problematize the formulaic notion of Broadway musicalsthe Superior Other!which implies a global hegemony that does not, in fact, exist because the boundary between the global and the local as well as the power dynamics of global culture are not fixed but constantly moving and changing. Today's musical scene in Korea shows interesting reversals from the 1990s, when Korean producers were eager to debut on Broadway and impress American audiences. Korean producers no longer look up to Broadway as a final destination; instead they want to make Seoul a new Broadway. They import Broadway musicals and turn them into Korean shows. The glamor of Broadway is no longer the main attraction of musicals in Korea. What young audiences look for most is the glamor of K-pop idols and utopian feelings of abundance, energy, intensity, transparency and community, which they can experience live in the musical with their favorite stars right in front of their eyes. In conclusion, I delve into the complex dynamics of recent Korean musicals with Thomas Friedman's theory of Globalization 3.0 as reference. The binary formula of Global/America versus Local/Korea cannot be applied to the dynamic and intercultural musical scene of today. Globalization is not a uniform phenomenon but rather a twofold (multifold) process of global domination and dissemination, in which the global and the local conflict and are conflated constantly. As this study tries to illuminate, the Korean musical has evolved in a huge net of interdependences between the global and the local with a range of sources, powers and influences.

전 세계적으로 기후변화 및 다양한 삶의 패턴이 변화되면서 예상되는 자원의 부족을 해결하기 위한 많은 노력이 진행되고 있다. 특히 범 국가적으로 지속가능한 자원안보 실현을 위한 적정 솔루션을 제공하고 자원의 연계에 따른 효율성과 효과성을 극대화하기 위해 물, 에너지, 식량의 연계를 통한 기술을 개발하고 적용하고 있으나, 아직까지 국가단위의 대규모 사례는 부족하며, Community Scale의 형태로 진행되고 있는 실정이다. 본 논문에서는 국내에서의 물, 에너지, 식량의 연계 기술을 도출하기 위해 국외에서 진행되고 있는 기술에 대한 현황과 효과를 분석하여 국내의 적용방안에 대해 분석하고자 한다. 국외의 사례로는 프랑스 전력공사(EDF)에서는 2000년 초반 기존의 규정대로 물공급을 지속하면 발전에 어려움이 발생하는 것을 인식하여, 주요 농업 관개시설과 물절약협약을 체결하고 물절약에 따른 금전적 보상대책을 마련하였다. 이를 통해 물 절약의 30%는 기존의 관행과 관리방식의 변화에 의해 이루어졌고, 약 70%는 효율적 물 사용기술을 통해 절감효과를 도출하였다. 또한 관개용수와 발전량의 효율적 물사용을 통해 3억2,500만$m^3$에서 2억3,500만$m^3$ 으로의 절감효과를 달성할 수 있었다. 오스틴 수도회사, 텍사스 가수 서비스, 오스틴 에너지 회사 등 텍사스의 3개회사가 상호 협약을 통해 다가구 에너지 및 물효율 프로그램을 개발하고 자원을 효율적으로 관리할 수 있는 주택을 개조하여, 연간 470만 kWh의 전기와 3,785만 리터의 물을 절약하고 있다. 베트남 Red강의 경우 베트남의 근대화 및 산업화를 위해 많은 물과 전기가 필요함에 따라 물사용량을 규제하였고 이로 인해 농작물 재배를 고려하여 장기적이고 다방면적인 전략을 도출하였다. 정유회사 CHEVRON에서는 미국 캘리포니아에서 오일 1배럴을 생산할 때마다 10배럴의 물을 생산하여 오일생산 과정에 이용하며 $182km^2$ 면적의 농장에 농업용수를 공급할 수 있었다. 특히, California 오일 추출과정에서 물과 오일을 분리하고 그 과정에서 발생한 물을 재이용하기 위하여 수처리과정을 통하여 매일 $2,650m^3$의 물 생산하게 되었다. 이러한 외국의 사례들을 바탕으로 하여 국내에서도 다양한 형태의 넥서스 기술을 접목하여 미래에 예측되는 자원 부족을 선제적으로 대응하는 방안을 수립할 때이다.

Aerobic granular sludge (AGS) can be classified as a type of self-immobilized microbial aggregates measuring more than 0.2 mm. It offers the option to simultaneously remove COD, N, and P that occur in different zones inside a granule. Also, AGS is characterized by high precipitability, treatability with high organic loading, and high tolerance to low temperature. In this study, a sequencing batch reactor inoculated with AGS (AGS-SBR) is a new advanced wastewater treatment process that was proven to grow AGS with integrated nutrient removal and low C/N ratio. A pilot plant, AGS-SBR with a capacity of 225 ㎥/d was installed at an S sewage treatment plant in Gyeonggi-do. The results of the operation showed that the water quality of the effluent indicated that the value of BOD5 was 1.5 mg/L, CODMn was 11.4 mg/L, SS was 6.2 mg/L, T-N was 13.2 mg/L, and T-P was 0.197 mg/L, and all of these values reliably satisfied an effluent standard (I Area). In winter, the T-N treatment efficiency at a lower temperature of less than 11℃ also showed reliability to meet the effluent standard of the I Area (20 mg/L or less). Analysis of microbial community in AGS showed a higher preponderance of beneficial microorganisms involved in denitrification and phosphorus accumulation compared with activated sludge. The power consumption and sludge disposal cost were reduced by 34.7% and 54.9%, respectively, compared to the domestic SBR type sewage treatment plant with a processing capacity of 1,000 ㎥/d or less.

중국의 아프리카에 대한 자원 외교는 성공적인 결과를 이루어내고 있다. 이러한 결과는 1990년대 이후 뚜렷하게 나타났던 '에너지 확보를 위한 원조 정책(aid-for-energy strategy)'처럼 단기간의 경제협력만으로 이루어진 것이 아니다. 중국은 1955년 반둥회의에서 아프리카와 첫 공식적인 외교 접촉을 가진 후 다양한 후원을 반세기 이상 지속하였다. 중국과 아프리카의 관계를 다룬 지금까지의 연구는 1990년대 이후 중국의 석유 및 천연자원 분야, 자원민족주의, 자원패권주의를 다루는 것에 편중되어 있었다. 따라서 이념으로 시작된 국제관계가 어떤 과정을 통해 정치 경제 분야로 파급되었는지에 대한 논의의 필요성이 제기되었다. 이러한 취지에서 본 연구는 1955년 '반둥회의'와 1957년 '아시아-아프리카 인민연대회의'를 중심으로 중국과 아프리카의 최초 공식 접촉과 그에 이어지는 관계의 발전을 고찰함으로써 중국의 대(對) 아프리카 정책의 초기단계를 이해하는데 목적이 있다.
