The object of this research is to elicit the ecological wetland's creating and maintaining conditions through GIS and AHP(Analytic Hierarchy Process) on common characteristics of wetland, by exploring the function of the long-standing and naturally created wetlands in South Han-river basin. Geomorphological, geologic, hydraulic & hydrological, pedological, environmental & ecological approaches of five categorizations were made based on the documents and precedent studies in order to perform the research object. Elicitation of the common creating and maintaining conditions on the objected wetlands through analysis of satisfactory conditions was conducted by performing an overlay analysis from the gathered information in each category and linking its result to each wetland. Also, elicitation of highly believable qualified analysis result was made by calculating the each factor's weight through application of AHP analysis method on each factor. The research result is expected to be applied effectively in suitability selection for creation of an artificial wetland and restoration and maintenance for naturally created wetlands when introducing the No Net Loss of Wetlands. In addition, with a new understanding on wetland and beyond the value of its conservativeness, this research result can be considered as a solution for Eco-Wetland's maintainable development.

This study aimed to understand the physiological status of the beet armyworm, Spodoptera exigua at low developmental threshold temperature (LTT) through analysis of gene-expression patterns associated with different functions (metabolism, nervous system, immune, and stress). The estimated LTTs for egg, larval, and pupal developments varied with $5.5{\sim}11.6^{\circ}C$. Larvae were able to develop at the lower temperatures than eggs and pupae. However, the physiological LTT ($15^{\circ}C$) in the fifth instar was much higher than the estimated LTT ($10.3^{\circ}C$). Gene expression patterns estimated by a quantitative RT-PCR (qRT-PCR) indicate that most genes in different functional groups increased their expressions with increase of larval instars. In the same fifth instar, as the treatment temperatures increased, the gene expression levels increased. Moreover, the newly molted fifth instar larvae were different in their gene expression rates according to their previous culturing temperatures. Most gene expressions were suppressed in the fifth instar larvae at the physiological LTT ($15^{\circ}C$). However, the larvae at $15^{\circ}C$ gradually exhibited significant increase in the gene expression rates with rearing time just like those at the higher temperature. These results suggest that S. exigua at LTT exhibits a typical gene expression pattern with maintaining significantly suppressed levels.

Co-operatives are a deep-rooted organization that was first organized in Britain in the 19th century and spread to Europe and North America in the early 20th century and to the rest of the world from the mid-20th century. Cooperative in Italy are fraternal (friendly societies) separated from religion, and in the early days of socialism and the late 19th century Catholic Italy, but independent of activity. And the Church's social participation, as well as multiple personalities. Therefore, the purpose of this study is to study the laws and institutions of Italian cooperatives. And let's look at how the laws and systems of Italian co-operatives support society and the national economy. Specifically, firstly, based on prior research, the concept of co-operatives and the cooperative movement and social values are considered. Second, review the development process and characteristics of Italian co-operatives and the legal system. Third, I would like to analyze the case of Italian co-operatives. Fourth, suggest implications according to the results of the study. The results of the study suggested the following. First, the attitude such as attachment and sincerity of representatives and staff of village enterprises is very important. Second, all members of the organization should participate in decision making with empathy and attachment to the vision of the village enterprise. Third, it should be highly likely that village enterprises, which can draw capital from outside according to the needs of the organization, will generate higher economic results. Fourth, it is important to establish a model of mind enterprise by presenting factors and success factors in establishing a village enterprise based on cases and theories. In conclusion, Co-operatives should contribute to social contribution rather than economic profit-seeking.

현재 태양광에너지 시장은 해마다 빠른 속도로 성장하는 추세이며 50 GWp/년 이상의 시장으로 변화하였고 앞으로도 전체적인 성장세는 지속 유지될 것으로 판단된다. 하지만 이와 아울러 각 Value chain 별로 많은 기업들이 생겨나게되어 각각의 기업들이 제품을 고효율 저가화 함으로서 경쟁력을 확보하기 위해 많은 노력들이 기울이고 있으며 본 강연에서는 이러한 측면에서 태양광 에너지의 분야별 고효율/저가화를 위한 기술동향을 살펴보고자 한다. 태양광 산업은 아직은 다소 높은 발전단가로 인해 일부 정부의 지원이나 정책에 의해 산업의 규모가 결정되게 되는데 주요한 지원제도는 RPS 제도와 FIT 제도가 있으며 우리나라는 초기 FIT 제도로 국가에서 태양광에서 생산된 전기를 높은 가격에 사주었으나 근래에들어 RPS 제도를 운영하게 되었으며 매전을 하면서 SMP에 준하는 수익을 창출하고 이와 아울러 REC 를 확보하여 확보된 REC 단가에 의해 추가적인 수익을 창출하는 구조의 발전사업이 진행되고 있다. 그리고 RPS나 FIT와 같은 정부의 지원없이도 발전단가의 경쟁력을 확보하는 시점을 그리드패러티라고 하며 이는 매우 중요한 의미를 갖는다. 태양광의 저가화는 그리드패러티 달성을 확보하기 위해 필수적으로 필요한 사안이며 앞으로도 이러한 저가화 / 고효율화 기술노력은 계속 진행될 것으로 판단된다. 우선 소재의 가격을 줄이기 위해 웨이퍼의 두께가 점점 박형화 되어가고 박형화 되면서도 안정적인 공정수율 및 효율을 향상시키기 위한 기술개발이 진행되고 있으며 Cell 분야에 있어서도 고효율을 위한 다양한 Texturing 기술 및 패시베이션 기술의 개발이 이루어 지고 있으며 고효율 컨셉의 MRT cell, Back contact cell 등 고효율 구조의 cell의 양산을 진행하고 있는 등 최근 n-type 기반의 고효율 cell 기술이 활발하게 양산화 검토가 이루어 지고 있다. 모듈 분야에 있어서는 저가/고효율화와 아울러 제품의 신뢰성 확보가 무엇보다도 중요하게 다루어 지고 있으며 이는 모듈이 최소 25년 이상 Field 에서 운용되어 수익창출이 가능해야 하므로 가장 중요한 요소중에 하나라고 할 수 있다. 신뢰성 측면에서 중요하게 다루어 지고 있는 것 중 하나가 PID 저감을 위한 노력이며 이와 관련된 각 소재의 개발이 가장 활발하게 진행되고 있으며 이와 아울러 장수명을 보장하기 위한 내구성이 겸비된 봉지재의 개발 또한 많은 관심을 불러 일으키고 있다. 저가/고효율화를 위해 CTM loss를 줄이기 위한 다양한 시도가 이루어지고 있으며 특수 형태의 리본으로 빛의 흡수를 증가시키거나 컨택저항을 최소화 하기위한 소재의 개발이 이루어 지고 있다. 태양광 시스템 분야의 경우 발전량과 수익창출에 있어 직접적인 영향을 미치는 분야로서 전체 시스템의 loss 를 줄이고 최적의 환경에서 최대한의 발전량을 확보하기 위한 array 설계 및 운용기술이 활발하게 개발되고 있으며 시스템에서의 loss를 줄여줄수 있는 마이크로 인버터나 multi string 인버터의 적용도 이루어 지고 있으나 저가화를 위한 추가적인 노력이 필요한 상황이다. 본 강연의 마지막으로 이러한 노력들의 산물인 특수 태양광 제품 및 시스템의 기술동향에 대해 살펴하고자 한다. 사막은 전체면적의 1/3을 차지할 정도로 넓은 면적을 자랑하지만 밤과 낮의 기온차 그리고 계통 선로의 부재 등 적용하기 어려운 환경적인 제약도 함께 존재하며 이러한 문제를 해결하기 위한 방안에 대해 살펴보고 최근 Hot issue 중의 하나인 수상 태양광 시스템의 장, 단점과 기술적 특성 등을 살펴보고자 한다.

An attenuated Japanese encephalitis virus (JEV) clone SA-14-14-2(Vero) was obtained through successive adaptation of a primary cell adapted strain, SA-14-14-2(PDK) to Vero cell, a continuous line of monkey kidney cells. The virus titer reached above the 107 plaque forming unit (pfu) per mL of culture supernatant with 3 passages in Vero cells and was maintained close to this level in the further passages. The optimum temperature for the virus growth was $35^{\circ}C$. Growth pattern of the virus indicated that optimum time for the virus harvest is 4 days post infection and the virus accomplished rapid initial propagation even in medium containing no serum supplement. The roller bottle (RB) system and the spinner flask (SF) system using micro-carrier (Cytodex-1) for the JEV cultivation were explored. When RB, SF, and T-flask culture system were compared, there was no significant difference in virus yield. Furthermore, the results indicated that virus could be harvested multiple times from 3 days to 9 days post infection; neither severe cytopathic effect (CPE) in the infected cells nor the decrease in the titer was observed on duration of 9 days.

This article examines the continuity and change of Korean welfare regime during 1990s. Democracy, globalization and the financial crisis changed the landscape of Korean society as a whole and provided a catalyst for the change of the Korean welfare regime. In order to show how and what changed in Korean welfare regime, this study concentrates on the transformations of income maintenance programmes and social welfare services. The changed aspects are as follow: (1) The ratio of social expenditure to GDP has increased during 1990s and now stood at ten percent level. (2)Rather than backing up the company welfare, government strove to build and expand income maintenance devices for all citizens. (3) The poverty and inequality reduction effects of income maintenance programs are very weak in early 1990s, but they are gradually getting stronger impact on poverty and inequality. But, there are also continuance. (1) In spite of the relative development of income maintenance programs, social welfare services are still poorly designed as before. (2) The expenditure level of social welfare services shows sharp contrast to income maintenance programs and lagged behind the other OECD countries. (3) The expansion of social service sector employment are also not so salient. In 2002, social service employment is only at close to 2.5 per cent of the total employment. Accordingly, korean welfare regime is now characterized by a model which is to curb poverty and inequality by engaging in direct government provision of income maintenance programs, but refrain from expanding social service by relying on net welfare which encourage the provision of services within the family. A implication of our analysis is that the expansion of social welfare Korea saw after 1997 was not really an regime shift. According to the arguments of Peter Hall, first and second order changes in policy do not automatically lead to third order changes which imply regime shift. Policy changes which occurred during 1990s was not accompanied by a shift in policy paradigms. Family dependency in welfare is not yet changed.

Nephrogenic diabetes insipidus (NDI) is a disorder in which the secretion of antidiuretic hormone is normal, but the response of the renal collecting tubules to vasopressin is impaired. Compared with acquired NDI (a-NDI), which is secondary to chronic bilateral incomplete urinary tract obstruction with hydronephrosis, congenital NDI (c-NDI) is a very rare heritable disorder that usually follows the X- linked recessive pattern. Clinical symptoms of c-NDI can be non specific, and often the disease ultimately results in failure to thrive, or mental retardation. Recently, the diagnosis can be confirmed by direct sequencing analysis of the peripheral blood specimens. The long-term results of treatment for c-NDI are not satisfactory. Reports on the follow up of c-NDI cases are rare and there is no report on the cases treated with combinations of three drugs. We report herein a case of severe c-NDI in an 8 year-old-boy with a severely dysconfigurated urinary tract system. The patient and his mother showed a frameshift mutation on the AVPR2 gene on chromosome Xq28:.847_851delTGCTG (p.C283fsX90). The patient showed normal growth and development by treatment with combinations of hydrochlorothiazide ($65mg/m^2$), amiloride (0.3 mg/kg/d) and indomethacin ($100mg/m^2$), yet after five years he needed adjuvant cystostomy to relieve him from the residual symptoms of urgency with polyuria.

Busan Biennale, began from 2000, has been argued that it would improve 'intrinsic introspection related to localism' against 'a lifestyle forced by capitalism in a global dimension', by promoting urban esthetic imagination in the public sphere of the city and reflecting it upon exhibited artworks. But Busan Biennale seems to reflect partly an attempt for new place marketing or urban reimagineering as a part of postmodern culture, even thought it has been planned to be an authentic stage or public-place art for citizens. This paper is to examine Busan Biennale 2006, held from Sep.16 to Nov.25 in Busan main theme of which is 'everywhere', constituted with three major projects: the Contemporary Art Exhibition, Sea Art Festival, and the Busan Sculpture Project. Ths paper considers first some implications of the transformation of modem to postmodern city, focusing on spatial representation of the city and public place art, and then tries to evaluate whether Busan Biennale is really embedded in the local authenticity and esthetic imagination for citizen or not. As concluding remarks, this paper suggests that Busan Biennale would be continuously developed, when it is oriented more towards local public-place art for citizens with their active participations rather than towards urban reimagineering strategy to make and promote an image of Busan as a global city.
