물에 대해 수착선택성이 높은 아세트산 셀룰로오스 치밀막(CA막)과 에탄올에 대해 수착선택성이 높은 실리콘 고무막(SR막)을 통한 물(1)/에탄올(2) 이성분 혼합액의 투과증발에 있어서 막의 친화성과 최적 조업조건의 관계를 조사하였다. CA막과 SR막을 제조하여, 이들 막에서의 수착량, 수착선택도, 투과증발 분리도 및 투과증발 속도를 실험으로 구하고 서로 비교하였다. 하류압력의 영향을 Thompson다이아그램을 써서 분석하였고, 공급액 농도와 조업 온도 변화에 따른 수착 및 투과증발 특성을 활동도 계수, 가소화 효과, 활성화에너지 등으로 설명할 수 있었다. CA막을 사용한 물의 분리의 경우에는 물에 대한 투과증발 분리도 ($[\alpha^2_1]_{PV}$) 및 투과증발 속도 모두 하류압력이 낮고, 공급액의 농도가 중간 정도이고, 온도가 높은 조업조건이 유리하였다. 그러나 SR막을 사용한 에탄올의 분리의 경우에는 에탄올에 대한 투과증발 분리도 ($[\alpha^2_1]_{PV}$) 는 하류압력이 높을수록, 공급액 중의 에탄올 농도가 낮을수록, 조업온도가 낮을수록 증가하였지만, 투과증발 속도는 반대의 경향을 나타내었다.

The previous studies argue that using the semantic properties of BIM objects is efficient for simulating the behaviors of autonomous, computer agents, called virtual-users, but such assumption is not proven via evidence-based research approaches. Hence, this present study aims to investigate the empirical effects of a human behavior simulation model equipped the semantics of spaces on the architecture-major students' operation and understanding of the simulation system, compared to a typical path-finding model. To achieve the aim, this study analyzed the survey and interview data, collected in the authentic design projects. The analysis indicates that (1) using a simulation model equipped the semantics of spaces helps the students' operation of the simulation, and (2) it also aids understanding the relationship between the variables of spaces and virtual-users (${\alpha}=0.74$). In addition, the qualitative data inform that the advantages of the simulation model that computes the semantics of spaces stem in the automatic behavioral changes of massive numbers of virtual-users, and efficient detection and activation on the what-if situations. The analysis also reveals that the simulation model has shortcomings in orchestrating the complex data structure between the semantics properties of spaces and virtual-users under multi-sequential scenarios. The results of this study contribute to develop a future design system combining BIM with human behavior simulation.

The purpose of this study is to analyze the level of public data convergence capabilities of administrative organizations and to explore important variables in data-based organizational capabilities. The theoretical background was summarized on public data and use activation, joint use, convergence, administrative organization, and convergence constraints. These contents were explained Public Data Act, the Electronic Government Act, and the Data-Based Administrative Act. The research model was set as the data-based organizational capabilities effect by a data-based administrative capability, public data operation capabilities, and public data operation constraints. It was also set whether there is a capabilities difference data-based on an organizational operation by the level of data convergence capabilities. This study analysis was conducted with hierarchical cluster analysis and multiple regression analysis. As the research result, First, hierarchical cluster analysis was classified into three groups. It was classified into a group that uses only public data and structured data, a group that uses public data on both structured and unstructured data, and a group that uses both public and private data. Second, the critical variables of data-based organizational operation capabilities were found in the data-based administrative planning and administrative technology, the supervisory organizations and technical systems by public data convergence, and the data sharing and market transaction constraints. Finally, the essential independent variables on data-based organizational competencies differ by group. This study contributed. As a theoretical implication, this research is updated on management information systems by explaining the Public Data Act, the Electronic Government Act, and the Data-Based Administrative Act. As a practical implication, the activity reinforcement of public data should be promoting the establishment of data standardization and search convenience and elimination of the lukewarm attitudes and Selfishness behavior for data sharing.

The purpose of this study is to verify the result of the previous studies and to clarify the types and activation factors of maintenance activities of the naturally favorable water space through the participation of residents in rural areas, through a further survey of the area proposed as a program in the existing study review and previous study related to the participation of residents. The survey was conducted through the survey of 1,242 households and 1,335 persons intended for Japanese rural areas. The study result is summarized as follows. The types of the maintenance activities in the areas intended for the survey have been classified into 'rural type' and 'combination type' through the analysis results by the references like the comparison analysis, job percentage and main utilization purpose of facilities for each type of maintenance and operation activities. In case of the 'rural type' area, residents were doing maintenance activities centered on the group activities rather than personal maintenance activities. Also, the activities of maintenance & operation group members were more active than non-members, and the water-friendly utilization to the facilities was not directly affecting the maintenance activities of residents. In case of the 'combinational type' area, there was no common characteristic according to each area, and the participation percentage in the maintenance activities was low compared with the 'rural type' area. According to the analysis result based on the participation degree of personal maintenance activities, the repair of facilities as a naturally favorable water space, implementation of projects reflecting the opinions of residents, educational programs conducted in order to motivate the participation of residents, etc. have been analyzed as the factors affecting the activation of maintenance activities of residents. Through the above results, for continuous maintenance activities to be made with residents as a main body in the future, it is necessary to support maintenance groups on an administrative level and procure experts for the production and operation of programs that can increase the participation percentage of residents.

본 연구는 경북농공단지를 중심으로 운영실태 및 현황 등을 살펴보고 이를 통해 활성화 방안을 제시하고자 한다. 경북농공단지의 가장 큰 문제점은 업체 간 연계가능성이 매우 희박한 여러 유형의 업체들이 단순 집적한 형태가 대부분인 것으로 나타났다. 또한 젊고 우수한 인력이 도시로 지속적으로 유출되고 있고, 대부분의 농공단지가 오래전에 조성되어 기반시설이 매우 열악한 상황이다. 따라서 이러한 문제점을 해결하기 위해서는 우선 농공단지를 특성화하도록 유도해야 한다. 예를 들어 구미국가 산업단지의 인근의 농공단지는 전기전자로 특화된 농공단지를 조성하도록 지원해야 할 것이다. 또한 경북농공단지의 산업구조 고도화를 추진하여야 한다. 농공단지 관리업무의 효율화를 위한 전략 또한 마련되어야 한다. 전문 운영기관에 관리운영을 위탁 하거나 혹은 농공단지별 정보화사업을 실시하여 자체적으로 운영을 하도록 지원하는 방안 또한 마련되어야 할 것이다. 마지막으로 산업단지 클러스터와의 연계를 통한 활성화 방안을 고려해봐야 할 것이다.

This research is to apply the adaptive control of neuron networks for the real-time attitude control of Multi-articulated robot. Multi-articulated robot is expressed with a complicated mathematical model on account of the mechanic, electric non-linearity which each articulation of mechanism has, and includes an unstable factor in time of attitude control. If such a complex expression is included in control operation, it leads to the disadvantage that operation time is lengthened. Thus, if the rapid change of the load or the disturbance is given, it is difficult to fulfill the control of desired performance. In this research we used the response property curve of the robot instead of the activation function of neural network algorithms, so the adaptive control system of neural networks constructed without the information of modeling can perform a real-time control. The proposed adaptive control algorithm generated control signs corresponding to the non-linearity of Multi-articulated robot, which could generate desired motion in real time.
