기후 변화로 인해 벼 병해충 예찰과 방제가 더욱 어려워지면서 주곡인 쌀의 생산량이 지속적으로 감소하고 있다. 이 연구에서는 그래프 이론을 적용하여 전국 시 군 지역을 대상으로 행정구역 단위의 벼 병원균 확산 공간 연결망을 정량적으로 분석하였다. 병원균 확산 연결망의 중추적 경로는 서해 연안의 행정구역 간에 연결된 링크들인 것을 확인할 수 있었다. 서해 연안 지역들은 병원균에 대한 경관 저항성이 매우 낮았고, 서해 연안의 핵심지역들과 경남 경북의 핵심지역들을 연결시키는 허브지역들을 도출할 수 있었다. 연구 결과를 통해 병원균 확산을 예측하고, 병원균이 발생하였을 때 확산을 방지하기 위해 우선적으로 방제되어야 하는 지역이 어디인지를 구분할 수 있었다. 연구결과는 병해충 방제 공동대응을 위한 행정구역 단위의 방제 구역 할당과 통합적인 병해충 관리계획 수립에 있어 유용한 농업환경지리 공간 자료로 활용될 수 있을 것이다.

The purpose of the study is to investigate the characteristics of the elderly housing preference and spatial usage to plan floor space of the elderly housing by the respondents of the ages 50 to 79. Based on the result of the study, it is suggested that the elderly housing should be located in regards to social environmental factors rather than natural environmental ones. There are differences in preference for the space planning of housing units such as the number of rooms and bathrooms, and floor space depending on income level, so the housing should be differently planned to accept the difference of preference. On the other hand, there is not notable difference in furniture preference for each space. In the characteristics of spatial usage according to behaviors, high-income respondents demonstrate the characteristics of spatial usage in accordance with a western lifestyle. Thus, behaviors such as sleeping, watching TV, resting, reading, conversation, and receiving guests, occur using such things as beds, sofas, and dinning tables. On the other hand low-income respondents show a mixed western and traditional lifestyle. Thus many behaviors are done on the floor of bedroom and livingroom in addition to using furniture such as a sofa and chairs. Therefore, the way of spatial usage has to be reflected in the floor space planning. At least floor space of the provided rooms should be planned to accommodate the behavior of the elderly even though all of the rooms preferred can not be provided.

The purpose of this study is to analyze neighborhood environmental factors affecting bicycle accidents and accidental severity in Seoul, Korea. The use of bicycles has increased rapidly as daily transportation means in recent years. As a result, bicycle accidents are also steadily increasing. Using Traffic Accident Analysis System (TAAS) data from 2015 to 2017, this study uses negative binomial regression analysis to identify neighborhood environmental factors affecting bicycle accidents and accidential severity. The main results are as follows. First, bicycle accidents are more likely to occur in commercial and mixed land use areas where pedestrians, bicycle and vehicles are moving together. Second, bicycle accidents are positively associated with road structures such as four-way intersection. In contrast, three-way intersection is negatively associated with serious bicycle accidents. The density of speed hump or street tree is negatively associated with bicycle accidents and accidential severity. This finding indicates the effect of speed limit or street trees on bicycle safety. Fourth, bicycle infrastructures are also important factors affecting bicycle accidents and accidential severity. Bicycle-exclusive roads or bicycle-pedestrian mixed roads are positively associated with bicycle accidents and accidential severity. Finally, this study suggests policy implications to improve bicycle safety.

Recent research in animal behavior has shown that gradient information plays an important role in finding food and home. It is also important in optimization of performance because it indicates how the inputs should be adjusted for maximization/minimization of a performance index. We introduce perturbation as an additional input to obtain gradient information. Unlike the typical approach of calculating the gradient from the derivative, the proposed processing is very robust to noise since it is performed as a summation. Experimental results prove the validity of the process of spatial gradient acquisition. Quantitative indices for measuring the effect of the amplitude and the frequency are developed based on linear regression analysis. Drones are very useful for environmental monitoring and an autonomous path planning is required for unstructured environment. Guiding the drone for finding the origin of the interested physical property is done by estimating the gradient of the sensed value and generating the drone trajectories in the direction which maximizes the sensed value. Simulation results show that the proposed method can be successfully applied to identify the source of the physical quantity of interest by utilizing it for path planning of an autonomous drone in 3D environment.

최근 도시계획분야에서 관심의 대상이 되고 있는 저영향개발기법은 강우관리 및 비점오염원 저감 뿐만 아니라 사회적, 경제적, 심미적으로 다양한 가치를 지니는 지속가능한 성장을 유도하는 통합적인 개발의 틀로서 이해되고 있다. 수변지역 개발에 대한 관심이 증대되면서 저영향개발기법에 대한 관심 역시 증대되고 있지만 계획과정 및 요소에 대한 연구는 부족한 실정이다. 본 연구는 두 가지의 목적을 지닌다. 하나는 저영향개발기법에 대한 선행연구검토를 통하여 계획과정 및 요소를 도출하는 것이고 다른 하나는 도출된 계획과정 및 요소를 모의적용과정을 통하여 효과를 파악하는 것이다. 저영향개발기법의 적용은 토지이용계획의 변화를 기초로 하였다. 이는 보전지역 및 공공시설 구역의 기능설정, 투수면적 확대를 위한 공간배치계획, 분산형 빗물관리체계 구축을 위한 공간배치계획 등으로 구분된다. 본 연구는 LIDMOD2를 이용하여 사례지역에서의 저영향개발기법 모의적용 효과를 추정하였다. 그 결과 연간표면 유출량, 연간 침투량, T-N, T-P, BOD, 첨두유량 등에서 7~10% 정도의 효과가 있는 것으로 나타났다.

The primary purpose of this research was to set up the standard guidelines for the planning of interior architectural environments of the detention facilities at the Korean Police Stations. By visit-studying the actual interior environmental conditions of 5 different kinds' domestic Correcting Facilities and 5 domestic police detention facilities and 2 foreign police detention facilities, comparing them to the existing Korean correctional institutions' cell facilities, that the strengths and weaknesses had been analyzed to extract the main concepts and the planning scheme for the Standard Korean Police Detention Facilities. By reserching the National human Right Commitee's Anual Reports, three different indexes were picked out for those analysis : the Environmental control index, the Detention Service support index, the Environmental support index. These three indexes will be used as Key factors for the planning of interior architectural environments of the detention facilities at the Korean Police Stations.: (1)the Environmental control index to establish the Space Program, the Spatial Hierarchy and the horizontal & vertical Security Blocks, (2)the Detention Service support index for the central Environmental Control & Security System, the Secured Privacy for both detainees & police offices, (3)the Environmental support index for the gender-respected segregation of cell zones, the psychological & physical safety design factors, the construction standards of all rooms in a detention facility. The result of this study should be used as the guidelines for "The Standard Plans and Regulations for the Korean Police Detention Facilities" to respect fundamental human rights.

In the process of exploring sustainable development, major cities in China are expanding metro systems as a strategy to reduce the negative environmental and social consequences of fast-paced motorization. A metro station is not only a transportation node, but also a place where diverse activities can be performed. Therefore, the realization of the spatial potential for human interaction is the essence of the strategy for integrated development in metro station areas. For this paper, 10 well-developed metro stations in Central Shanghai were selected to investigate the correlation between accessibility and spatial performance in station areas. The spatial performance in station areas is significantly affected by metro configuration. However, both vehicle and pedestrian accessibility show weak influence on spatial performance. A synergistic model was then developed to provide quantitative support for transit-oriented development in metro station areas.

Place based intervention has become an important strategy for the ubiquitous city initiative. However, the role of the ubiquitous built environment in determining urban quality of life has not investigated fully. Using place as a relational space where people access u-infrastructure, u-health and u-services, this paper examines the relationship between spatial variations in the provision of ICTs and the spatial reconfiguration of quality of life operating at different geographical scales across Australia. Based on a case study of the state of Queensland in Australia, we emphasize the need for a place based approach to ubiquitous technologies and infrastructure provision in different socio economic hierarchies of space and place.
