Purpose - With the increasing number of small business owners who reports the cessation of their businesses, the rate of closing the business within the year is increasing as well. The efforts have been made continuously to revitalize the business through the inflow of government or private capital. Maintaining the fast-changing commercial districts with the existing support is difficult, so it is urgent state that needs for commercial district reorganization. The differentiate aspect is that this new measures for small-block-unit commercial modeling can be introduced to promote these aging/deposit private-owned shops politically. Research design, data, and methodology - This study is to develop a sustainable theme shopping rehabilitation method which considers the characteristics of local cities based on the case studies of developed countries' commercial areas to revitalize the central urban areas of local cities. Results - The purpose of this study as stated above is to manage the local commercial area through the program that purchases the empty stores, and the measure to secure the autonomy among stores. Conclusions - The government should concentrate on projects such as vacant store purchase programs, which are omitted from past achievements, and maximize the effect of the project through inter-departmental project packages.

Recently, the population growth, industrial and agricultural development are rapidly undergoing in the Lower Rio Grande Valley (LRGV) in Texas. The Lower Rio Grande Valley (LRGV) composed of the 4 counties and three of them are interesting for Non-point and point source pollutant modeling: Starr, Cameron, and Hidalgo. Especially, the LRGV is an intensively irrigation region, and Texas A&M University Agriculture Program and the New Mexico State University College of Agriculture applied irrigation district program (Guy Fipps and Craig Pope, 1998), projects in GIS and Hydrology based agricultural water management systems and assessment of prioritized protecting stream network, water quality and rehabilitation based on water saving potential in Rio Grande River. In the LRGV region, where point and non-point sources of pollution may be a big concern, because increasing fertilizers and pesticides use and population cause. This project objective seeks to determine the accumulation of non-point and point source and discuss the main impacts of agriculture and environmental concern with water quality related to pesticides, fertilizer, and nutrients within LRGV region. The GIS technique is widely used and developed for the assessment of non-point source pollution in LRGV region. This project shows the losses in kg/$km^2$/year of BOD (Biological Oxygen Demand), TN (total Nitrogen) and TP (total phosphorus) in the runoff from the surface of LRGV.

국토해양부에서는 건설산업의 정보화 수준을 향상시키고 건설 생산체계를 효율화시키기 위해서 건설 CALS(Continuous Acquisition & Life-cycle Support)사업을 추진하고 있다. 건설CALS사업은 1998년부터 시작되었지만 건설CALS의 정보화수준은 어느 정도인지에 대한 측정이 없었다. 본 연구에서는 선행연구에서 도출된 평가지표를 사용하여 건설CALS의 정보화수준을 측정하였다. 연구는 설문항 및 표본 구성, 설문조사, 설문조사 결과 분석의 절차로 진행하였다. 설문조사 결과, 빠른 시스템 장애복구, 시스템의 웹환경 구축, 높은 표준분류체계 활용, 체계적인 정보전략 계획 수립 측면에서 우수한 것으로 판단된다. 본 연구에서 제시하는 결과는 건설CALS의 정보화수준을 정확히 파악하는데 기여할 것이라 생각된다.

The loss of mandibular continuity due to trauma, neoplasm, or infection results in major esthetic and biologic compromise. The reconstruction of the mandibular bone defect still poses a challenge to oral and maxillofacial surgeons. There have been a number of variety graft materials. Among them, free block bone graft with rigid fixation has been widely used. However, cases using free block bone grafts may lead to a marked invasion of the donor site, mal-union, and absorption of the block bone. In this respect, particulate cortical bone using a titanium mesh tray can be an effective alternative option in order to achieve a proper bone contour and good oral rehabilitation. We have developed an intraoral approach for the mandibular reconstruction method using a titanium mesh tray with autogenous particulate cortical bone graft.

WTO/TBT requires that, for technical regulations affecting trade, technical regulatory requirements must be specified where possible in terms of performance rather than design or descriptive characteristics. The movement which made "performance" a keyword in landscape architecture was activated in Japan, one of the leading counties in performance-based regulatory system(PBRS). The Japanese recent movement of systematization activity on performance-based standards and specifications was reviewed and operational applications for performance-based regulatory system in South Korea are summarized as follows: 1. The establishment of performance standards that can be properly evaluated by assessment indicators is necessary in cases when quantitative evaluation is difficult. 2. As a preparation for PBRS, a brief procurement system by technical proposal for the landscape design and construction is necessary. 3. As a preparation for PBRS, activation of an environmental performance evaluation on experimental construction is necessary. 4. As a preparation for PBRS, a certification system of environmental performance on various landscape construction methods is necessary. 5. The Private Finance Initiative Project is the most similar to PBRS therefore, activation of the Private Finance Initiative Project is necessary in landscape architecture projects for park rehabilitation.

With the recent advances in radiological science, there was radiographic techniques development and several researches to diagnosing dysphagia. We proposed the new Imaging technology based on Near Infrared radiation (NIR) for video fluoroscopic swallowing study (VFSS). To reduce the risk of the VFSS examination for swallowing rehabilitation, multi-NIR camera system comprised. Based on the multi-NIR camera imaging system, Computational simulation was conducted to identify the potential of the multi-NIR camera imaging system as a clinical tool (screening system). As a result of the simulation applied in this study, the proposed system has a potential to be a clinical solution although there is a few of limitations. we believe that it will be a good tool to support the VFSS as a screening technology in clinical fields.

Cost-Benefit Analysis (CBA) is a systematic optimization process that allows users to compare different alternatives and to determine if a project is a solid investment. Many state DOTs have included CBA in their pavement management systems (PMSs) to help allocate state funds for maintenance, rehabilitation, resurfacing, and reconstruction of pavements. In a typical CBA, each pavement type has an assigned weight factor which represents the level of importance of this pavement type. To conduct an accurate CBA, it is essential to select appropriate weight factors. Arbitrarily assigning weights factors to pavements can lead to biased and inaccurate funding allocation decisions. The purpose for this paper is to outline a method to develop an ideal set of weight factors that can be utilized to conduct more accurate CBA. To this end, a matrix of all possible weight factors sets was developed. CBA was conducted for each set of weight factors to obtain a population of possible optimization solutions. Then a regression analysis was performed to establish the relationship between benefit and weight factors. Finally, a multi-objective genetic algorithm was applied to select the optimal set of weight factors. The findings from this study can be used by state DOTs to strategically manage their roadway systems in a cost effective manner.

온실가스 배출로 인한 기후변화가 심각한 문제로 대두되면서, 국내 외에서 건물 에너지 절감을 위한 노력이 전개되고 있다. 특히, 국내 주거용 건축물 사용단계의 에너지 사용에 따른 온실가스 배출량은 전 생애주기에서 매우 큰 비중을 차지하고 있으며, 노후 공동주택의 수가 급격히 증가하고 있는 상황에서 기존 공동주택의 개선을 통한 에너지 절감의 중요성은 더욱 높아지고 있다. 그러나, 기존 공동주택의 개선에 대한 의사결정 과정에서, 에너지 절감에 대한 부분은 주요 고려사항으로 반영되지 못하고 있으며, 이를 반영하기 위해 필요한 의사결정 지원도구 역시 미비한 실정이다. 본 논문은 공동주택 개선여부의사결정 단계에서 활용할 수 있는 의사결정 지원 시스템을 개발하는 첫 단계로서, 유사 특성을 지닌 공동주택 단지간의 군집을 형성하는 분류체계를 구축하고자 했다. 이를 위해 데이터마이닝 기법 중 하나인 의사결정나무를 활용하여 공동주택 단지 특성 및 전력, 가스, 지역난방 에너지 사용량 기반의 군집을 형성했다. 향후 본 연구의 결과를 더욱 발전시켜 공동주택 개선단계에서의 의사결정 시 에너지 사용량을 고려사항으로 반영함으로써, 노후 공동주택 개선을 통한 에너지 절감 및 이산화탄소 배출량 감축 효과를 극대화할 수 있을 것으로 기대된다.

재해로 인한 부상 및 만성 질환 등의 다양한 요인으로 신체적 장애를 가진 환자, 혹은 신체의 노화로 인하여 몸의 움직임의 범위가 제한된 노인과 같은 경우, 치료의 일종으로 병원에서의 재활 프로그램의 참여를 권장 받는 경우가 있다. 그러나 이들은 신체의 거동이 불편하므로 보호자의 동행 없이 재활 프로그램의 참여를 위한 이동이 쉽지 않다. 또한, 병원에서는 각각의 환자 및 노인들에게 재활 운동을 지도해주어야 하는 불편함이 존재한다. 이러한 이유로, 이 논문에서는 모션 인식을 통하여 집에서도 타인의 도움 없이 재활 운동이 가능한 원격 재활 프로그램을 개발하였다. 해당 시스템은 사용자 집의 스테레오 카메라와 컴퓨터를 이용하여 구동할 수 있으며, 모션 인식 기능을 통하여 사용자의 실시간 운동 상태 확인이 가능하다. 사용자가 재활 운동에 참여하는 동안, 시스템은 사용자의 특정 부위의 관절가동범위(Joint ROM; Joint Range of Motion)를 저장하여 신체 기능의 향상도를 확인한다. 이 논문에서는 시스템의 검증을 위하여 총 4명의 실험군이 참여하였으며, 총 3종류의 운동을 각 9회씩 반복한 데이터를 이용하여 각 실험군의 시작 및 마지막 운동의 관절가동범위의 차이를 비교하였다.
