국내의 늘어나는 천연가스의 수요를 충족시키면서 지구온난화에 대한 대안으로 바이오가스를 도시가스로 활용하는 방안이 자연스럽게 주목받고 있다. 도시가스사업법의 개정을 통해 바이오가스의 생산 및 공급의 제도적인 기반을 구축했지만, 바이오가스내의 불순물을 제거하고 이산화탄소를 분리하여 고순도의 메탄을 제조하는 국내 기술이 부족하여 실질적인 활용이 어려운 상황이다. 따라서 본 연구에서는 고순도의 바이오메탄 농축을 위하여 멤브레인(Membrane)법, 물흡수법(Water absorption), 화학흡수법(Chemical absorption), 흡착법 4가지의 공법을 적용하여 각 시스템별 운전시나리오를 작성하고 비교하여 최적공법을 도출하였으며, 시스템별 케이스 연구를 통해 최적의 시스템을 구축할 수 있었다. 이를 이용하여 순도 97%이상의 바이오메탄을 생산하여 도시가스로 이용하기에 충분하였으며, 회수율이 98%를 넘어 그간 경제성이 없어 버려지던 소량의 바이오 가스도 회수하여 활용 할 수 있게 되었다.

울산에서 출반한 지방공무원 퇴출제가 전국으로 확대되고 있다. 이는 지방자치단체마다 공무원개혁의 일환으로 능력과 자질이 부족한 공무원을 조직에서 퇴출시키려는 움직임이 강하기 때문이며, 또한 시민들의 공직에 대한 변화에 바람이 크기 때문이다. 이렇듯 지방자치단체에 불고 있는 울산발 무능공무원 퇴출제는 서울시를 비롯한 지방자치단체로 그리고 중앙부처로까지 확대되고 있다. 하지만 공무원 퇴출제에 대하여 우려하는 시각도 매우 강하게 제기되고 있다. 이에 본 연구에서는 최근 확대되고 있는 무능공무원 퇴출제에 대한 다양한 의견과 공직개혁에 대한 제도적 법적 이론적 검토를 통하여 퇴출제가 가지는 사회적 의미와 퇴출제에 따른 문제점을 살펴보고 이에 따른 개선방안과 향후 공무원 개혁의 방향성을 제시하고자 한다.

Existing methods for optimization of sequences by random mutagenesis generate libraries with a small number of mostly deleterious mutations, resulting in libraries containing a large fraction of non-functional clones that explore only a small part of sequence space. Large numbers of clones need to be screened to find the rare mutants with improvements. Library display formats are useful to screen very large libraries but impose screening limitations that limit the value of this approach for most commercial applications. By contrast, in both classical breeding and in DNA shuffling, natural diversity is permutated by homologous recombination, generating libraries of very high quality, from which improved clones can be identified with a small number of complex screens. Given that this small number of screens can be performed under the conditions of actual use of the product, commercially relevant improvements can be reliably obtained.

This paper introduced the appearance characteristics of the cab mask & telescopic handrail arms for the New Zealand EMU to be applied with inter-city transportation in 2010. The appearance characteristics are improvements of driver's sightline, implementation of safety zone of gangway plate by using the telescopic handrail arms, improvements of staff & female crew & ground crew's convenience. and also, during have looking the New Zealand EMU(Electric Multiple Unit), I hope that people who having the interesting of the cab mask design would be gotten help with basic knowledge.

The article compares economic and environmental performance of Taipei and Almaty from the point of view of "green" economy, which is able to act as a key tool to ensure sustainable development of the region. As the comparison of the parameters of ecological and economic development of the Taipei and Almaty cities shows, they are similar in population size, but demonstrate completely different trends of sustainable development. Economic performance of the Taipei city is achieved with a decrease in the consumption of natural resources and the production of pollution, while the situation in Almaty is the opposite. Almaty maintains a high level of air pollution due to the use of coal in electricity production, as well as increased traffic and density of construction, including the southern part of the city, which is a zone for the transit of mountain air flows. The article discusses the activities jointly conducted by the Government of Taiwan and non-governmental organizations on environmental issues, as well as environmental NGOs, which resulted in significant improvements in the environmental field. Measures to stimulate the development and implementation of environmental innovations applied in the field of sustainable development in the city of Taipei can be adapted for the city of Almaty, where the environmental situation deteriorates year by year.

On the assumption that marketing is a useful technique to activate park use, this study aims to find what benefits people pursue and how much they attain them through a park visit. To achieve this, the survey of a Benefits-Sought for a park was conducted at four major parks in the city of Taejon and an Importance-Performance Analysis(IPA) was conducted. Additionally, a Present Condition survey was performed with the park managers. As a result, first, it was found that major benefits are a comfortable rest, an escape from bustling city life, to see natural scenery and to promote physical health, and so forth. Second, performance was relatively lower than importance in the case of recreation and leisure activities, which means that facilities should be improved and programs for park use should be developed. Third, at GaYang park, importance and performance are good in balance. DongChunDang park and Seattle park have 5 items and 7 items for which immediate improvements are required. Saemmeury park generally shows good proportions and it can be much activated by improving the learning and experiencing activities. The results objectively show conditions of neighborhood parks in the city of Taejon from a view of park users. Therefore, it is expected that the results would be useful in determining priorities when improving park facilities or their programs.

The purpose of this study is to analyze the characteristic of common space of public schools in New York City and how the common space can perform a decisive role in enriching public space not as simply connecting between programs but as common space for a wide range of uses for communities as well as students. This study illustrates with a general design guideline of SCA(School of Construction Authority) and how the rules help the common space as an interactive link between community and site/site and school building/building and outdoor space/outdoor space and lobby in the urban context. Since its founding in New York City, 1958, Mitchell/Giurgola Architects office has dedicated itself to working with institutions and public and private schools for 50 years and has been working with SCA for 10 public schools since 1990. Through five school examples by Mitchell Giurgola architects, the study describes how the office suggests public "place" interweaving inner public space and outer public space through lobbies. A result of this research can be proposed what improvements should be made on common space in domestic schools by analyzing of positive aspects of SCA schools.

In the circumstances being continuous the unusual weather in the world, the city of Seoul has been devastating flood damage in July 2011, because of the heavy rainfalls. Along with expensive repairs to property, thousands of flood victims occurred; it is difficult to estimate the direct and indirect economic damages in city. Recently, as a part of the flood protecting measures, there are being discussed about the deep underground flood drainage tunnel, underground regulating reservoirs, permeable pavement, infiltration facility, river improvements, diversion channel, sewer pipe and ditch improvement and so on. Therefore, it is useful to make the plan of flood protecting measures more and more cost-effective and rational methods by considering the similar flood measures and constructions in the mega cities like Seoul.

This study is to suggest design types and to identify design characteristics of traditional style public buildings. Since the types of such buildings became very diverse recently, proper classification criteria is essential for future design and evaluation. The demand for such buildings is continuously increasing, but the types of design is very varied; thus it seems important to identify the present design conditions, and to be able to suggest desirable directions for better designs. The research analyzes 31 examples of public buildings in Gwangju Metropolitan City and South Jeolla Province, where there are large number of traditional style public buildings than anywhere else in Korea, and tried to analyzed site plan, elevation, space, details and organizes Design types. This study can help to roughly identify the problems of existing design as well as to suggest improvements in the future design.
