2015 대구 경북 세계물포럼은 국제기구, 각국 정부, 학계, 기업, 시민단체 등이 지구촌 갖가지 물 문제에 대한 해결책을 제시함과 동시에 실행을 위한 실질적 이니셔티브를 구축하는 전세계 최대의 물 관련 국제행사이다. 1997년 마라케시에서부터 헤이그, 교토/시가/오사카, 멕시코시티, 이스탄불, 그리고 마르세유를 거쳐 7차 대구/경북까지 물 유관기관 및 개인을 비롯한 물 이용자의 교류창구가 되어 물 관련 국제협력 파트너십을 기반으로한 국제사회 물 문제 해결에 기여해왔다. 2015년 대구 경북 세계물포럼은 2012년 열린 6차 마르세유 세계물포럼의 ‘Time for Solutions’에 이어 도출된 해결책들을 실제로 실행한다는 것을 기치로 삼아 ‘Implementation’을 키워드로 전 과정의 프로그램들을 기획, 운영을 계획하고 있다. ‘실행’의 추진체 역할을 하게 될 과학기술과정(Science and Technology Process)은 금번 포럼을 준비하면서 한국 정부가 제안하여 신설한 과정으로 전세계 물 문제 해결에 있어 과학과 기술의 중요성을 부각시키고, 성공사례를 공유하기 위해 만들어졌다. 가장 혁신적인 최신기술과 각 국가 환경 및 문제에 적합하고 적용 가능한 기술을 알리고 확산시키는 과정으로 지구촌 물 문제 해결에 기여할 수 있는 과학, 기술을 발굴하고, 제도와 경험을 공유하여 실질적인 교류 및 논의의 장을 제공하여 물관리 정책 성공사례 및 우수 물관리 기술을 공유하는 것을 목적으로 하고 있다. 타 과정들(주제별, 지역별, 정치적과정 및 시민포럼, EXPO)과의 긴밀한 연계를 통하여 과학기술과정의 결과를 충분히 공유하고 향후 과학, 기술을 이용하는 개체 뿐 아닌 관련 정책을 결정하는 담당자까지 함께 실행방안을 모색하기 위한 장을 만들기 위해 노력하고 있다. 특히 과학기술과정의 32개 세션들과 더불어 세 개의 특별 프로그램인 백서, CEO 이노베이션 패널, 그리고 월드워터챌린지는 과학, 기술에 특화된 내용과 구성으로 기획되고 있다. 백서제작을 통해 물 관련 과학기술의 현황분석을 통한 현주소 조명을 비롯해 향후 방향을 제시하고 CEO이노베이션 패널을 통해 국내외 대표기업 CEO, 정부 고위 공직자, 물관련 석학 등 고위급 인사의 소통의 장을 만들어내며 월드워터챌린지를 통하여 물 문제 당사자(Problem owner)와 최적의 해결책 제공자(Solution provider) 간 네트워크를 구축, 물문제 해결의 선사례를 만들 수 있는 방법론을 제시하고자 한다. 과학기술과정을 중심으로 한 2015 대구 경북 세계물포럼의 성공적 개최는 국제사회의 지구촌 물문제 해결을 위한 향로에 충분한 기여를 할 뿐만 아니라 향후 지속가능한 국내 물산업 해외진출의 기반을 형성하는 것을 목표로 준비에 박차를 가하고 있다.

This study has analyzed overseas projects of building rural communities using vacant houses. It is aimed at identifying the roles of NPO in the community-building projects and providing implications applicable to Korea. In recent years, there has been a spike in the number of vacant houses in rural areas. It is due to rapid urbanization and uneven distribution of the population across the country. Those are the reasons that prompted community-building projects. To solve the vacant house issue, there has been rising interest in building communities through vacant houses as rural resources and effectively integrating them as useful resources. However, the roles of key entity that pursues community-building projects using vacant houses have not been discussed sufficiently. Thus, this study deals with the 'Vacant House Recreation Project of NPO Corporation in Onomichi' in Hiroshima, Japan. Through the case study, the following are introduced as NPO's roles in community-building projects using vacant houses. First, pursuing promotion and attracting attention by making the utilization of vacant houses sensational; system improvement; offering information. Second, enhancing the perception of local residents by offering local services using vacant houses; offering community-building items. Third, forming a place of public discussion to solve conflicts during community-building projects using vacant houses; offering alternatives to building communities. Above all, such roles have led to the key status of NPO during its community-building projects using vacant houses. It offers the following implication for Korea: Future vacant house-related policies for rural revitalization should be done from community-building standpoint and include establishing the roles of NPO.

This study postulates a study model to examine the effect on the local economy revitalization of a selection of local resources, the local innovation capability strengthening, the establishment of promotion system and the creation of revenues for the participant groups of the local industry promotion project. To accomplish study purposes, 169 response samples from 85 project groups which drive the local industry promotion project were verified using SPSS 12.0 and AMOS 5.0. The results showed that firstly, the selection of local resources had a significant effect on the local innovation capability strengthening. Secondly, the local innovation capability strengthening had a significant effect on the establishment of promotion system. Thirdly, the establishment of promotion system had a significant effect on the creation of revenues. Fourthly, the selection of local resources didn't have an effect on the revitalization of local economy. Fifthly, both the local innovation capability strengthening and the establishment of promotion system didn't have an effect on the revitalization of local economy. Sixthly, the creation of revenues had a significant effect on the revitalization of local economy. According to the verifications of study model, the revitalization of local economy is achieved by inducing creation of revenues through the local innovation capability strengthening and the establishment of promotion system after the selection of local resources. From these results, this study presents suggestions, limits of study and directions in the future study.

This study is mainly focused on micellar effect of cetyltrimethyl ammonium bromide(CTABr) solution including alkylbenzimidazole(R-BI) on dephosphorylation of isopropyl-4-nitrophenylphosphinate(IPNPIN) in carbonate buffer(pH 10.7). The reactions of IPNPIN with R-BI⊖ are strongly catalyzed by the micelles of CTABr. Dephosphorylation of IPNPIN is accelerated by BI⊖ ion in 10-2 M carbonate buffer(pH 10.7) of 4×10-3 M CTABr solution up to 89 times as compared with the reaction in carbonate buffer by no benzimidazole(BI) solution of 4×10-3 M CTABr. The value of pseudo first order rate constant(kψ) of the reaction in CTABr solution reached a maximum rate constant increasing micelle concentration. Such rate maxima are typical of micellar catalyzed bimolecular reactions. The reaction mediated by R-BI⊖ in micellar solutions are obviously slower than those by BI⊖, and the reaction rate were decreased with increase of lengths of alkyl groups. It seems due to steric effect of alkyl groups of R-BI⊖ in Stern layer of micellar solution. The surfactant reagent, CTABr, strongly catalyzes the reaction of IPNPIN with R-BI and its anion(R-BI⊖) in carbonate buffer(pH 10.7). For example, 4×10-3 M CTABr in 1×10-4 M BI solution increase the rate constant(kψ=98.5×10-3 sec-1) of the dephosphorylation by a factor ca.25, when compared with reaction(kψ=3.9×10-4 sec-1) in 1×10-4 M BI solution(without CTABr). And no CTABr solution, in 1×10-4 M BI solution increase the rate constant(kψ=3.9×10-4 sec-1) of the dephosphorylation by a factor ca.39, when compared with reaction (kψ=1.0×10-5 sec-1) in water solution(without BI). This predicts that the reactivities of R-BI⊖ in the micellar pseudophase are much smaller than that of BI⊖. Due to the hydrophobicity and steric effect of alkyl group substituents, these groups would penetrate into the core of the micelle for stabilization by van der Waals interaction with long alkyl groups of CTABr.

재해의 발생원인 중 최근 가장 심각하게 인식되고 있는 것은 기후변화로서 집중호우의 증가, 가뭄의 증가, 태풍의 강도 증가 등 실재로 기후변화로 인한 재해의 가중이 발생하고 있는 상황이다. 재해위험경감을 위한 노력은 예전부터 각 국가별로 정도의 차이는 있으나 지속적으로 이루어져왔다. 그러나 21세기에 접어들면서 기후변화의 심각성이 이론뿐 아니라 현실로 나타나기 시작하면서 세계적으로 대형 재해가 급증하는 양상을 보이면서 각국의 우려는 더욱 증대되기 시작하였다. 특히 2004년 12월 발생한 남아시아 지진해일은 자연재해가 더 이상 국가 차원에서 다루어질 문제가 아니라 국가 간의 공조체제를 구축하여 공동 대응을 해나가야 할 심각한 현안으로 대두되었음을 인지하기 시작하였다. 본 연구에서는 기후변화 및 개발과 재해위험경감과 관련된 국내외 주요 선행연구 및 전략을 분석하여 기후변화와 재해 그리고 개발과 관련된 재해위험경감과 관련된 국제사회의 패러다임을 분석하였다. 기후와 재해 그리고 이와 관련된 개발과의 연관성을 분석한 결과 기후변화적응과 재해위험경감을 연계해야 할 필요성과 그 두 가지를 개발 계획과 의사결정에 주류화 해야 할 필요성을 확인할 수 있었다.

The Government had devised legislation of Special Act and drew up guidelines for improving air quality in Seoul Metropolitan area. In 2007 local government of Seoul, Incheon and Gyeonggi conducted the results of application policy by reduced air pollutants emission for the first time. Although there was reduction of air pollutant emission in each local government, it was ineffective as expected using air pollution monitoring database. Therefore we worked out a way to prepare modeling input data using the results of enforcement plan. And we simulated surface NO_2 and PM10 before and after decrease in air pollutants emission and examine reduction effects of air pollution according to enforcement regulation except other influence, by using MM5-SMOKE-CMAQ system. Each local government calculated the amount of emission reduction under application policy, and we developed to prepare input data so as to apply to SMOKE system using emission reduction of enforcement plan. Distribution factor of emission reduction were classified into detailed source and fuel codes using code mapping method in order to allocate the decreased emission. The code mapping method also included a way to allocate spatial distribution by CAPSS distribution. According to predicted result using the reduction of NOx emission, NO_2 concentration was decreased from 19.1 ppb to 18.0 ppb in Seoul. In Gyeonggi and Incheon NO_2 concentrations were down to 0.65 ppb and 0.68 ppb after application of enforcement plan. PM10 concentration was reduced from 18.2 ㎍/㎥ to 17.5 ㎍/㎥ in Seoul. In Gyeonggi PM10 concentration was down to 0.51 ㎍/㎥ and in Incheon PM10 concentration was decreased about 0.47 ㎍/㎥ which was the lower concentration than any other cities.

This study analyzed push, pull motivation factors and satisfaction of visitors who visited Yangdong village in order to maintain, conserve and seek for effective utilization of this village. The result of this study was summarized as follows. Firstly, the result was that 'personal relations' has a positive impact on 'regional environment' and 'amenities', 'the pursuit of knowledge' has a positive impact on 'regional environment' and 'amenities' on the correlation between the visit motivation and the visit satisfaction.

Physical environment was a only factor that has a positive impact on the visit satisfaction on a part of the pull factors. Thirdly, the intention of recommendation was a only factor to has a positive impact on the visit satisfaction on the correlation between the intention of return visit, recommendation and the visit satisfaction. It was proved that the intention of return visit was strongly associated with the intention of recommendation. This result of this study confirmed the important pull and push factor to enhance the tourist attraction of Yangdong village. It will be helpful to make the preliminary data for planning and conservation guidance of traditional village.

A simplified linearized dynamic equation for the propulsion force generation of an Ostraciiform fish robot with elastically jointed double caudal fins is derived in this paper. The caudal fin is divided into two segments and connected using an elastic joint. The second part of the caudal fin is actuated passively via the elastic joint connection by the actuation of the first part of it. It is demonstrated that the derived equation can be utilized for the design of effective caudal fins because the equation is given as an explicit form with several physical parameters. A simple Ostraciiform fish robot was designed and fabricated using a microprocessor, a servo motor, and acrylic plastics. Through the experiment with the fish robot, it is demonstrated that the propulsion force generated in the experiment matches well with the proposed equation, and the propulsion speed can be greatly improved using the elastically jointed double fins, improving the average speed more than 80%. Through numerical simulation and frequency domain analysis of the derived dynamic equations, it is concluded that the main reason of the performance improvement is resonance between two parts of the caudal fins.
