The solar cells should be operated at the maximum power point because its output characteristics are greatly fluctuated on the variation of insolation, temperature and load. Photovoltaic system needs an inverter which can interface the dc output power of solar cell with the residential ac load. The inverter has to supply a sinusoidal current and voltage to the load and the utility line with a high power factor. This paper proposes an utility interactive photovoltaic system designed with a step-up chopper and a PWM voltage source inverter. The step-up chopper operates in continuous mode by adjusting the duty ratio so that the photovoltaic system tracks the maximum power points of solar cell without any influence on the variation of insolation and temperature. The voltage source inverter operates in a manner that its output voltage is in phase with the utility voltage. The inverter supplies an ac power with high factor and low level of harmonics to the load and the utility power system.

Numerical liquefaction model and response history analysis procedure are verified based on dynamic centrifuge test results. The test was a part of the Liquefaction Experiments Analysis Project (LEAP). The model ground was formed inside of rigid box by using the submerged Ottawa F65 sand with a relative density of 55% and 5° of surface inclination. A tapered sinusoidal wave with a frequency of 1 Hz was applied to the base of the model box. Numerical analyses were performed by two dimensional finite difference method in prototype scale. The soil is modeled to show hysteretic behavior before shear failure, and Mohr-Coulomb model is applied for shear failure criterion. Byrne's liquefaction model was applied to track the changes in pore pressure due to cyclic loading after static equilibrium. In order to find an appropriate flow condition for the liquefaction analysis, numerical analyses were performed both in drained and undrained condition. The numerical analyses performed under the undrained condition showed good agreement with the centrifuge test results.

This study was carried out to analyze ecological characteristics and select target species for effective restoration plans of wildlife corridors at Galmachi of Sungnam City. The actual vegetation in study area was physiognomically mixed with deciduous broad leaved forests dominated by oaks and artificially planted species. And it is a secondary forest formatted by sprout originated stand and being on early succession stage as a young stand. So study site was regarded as not suitable for the habitats for wildlife. The number of mammal species at study site was total 22 species, but most of these species were found as not so many in individual numbers. The individual number of hare was approximately 4 to 8, while the raccoon dog and water deer with 2 to 3 and 1 to 2, respectively. As such, it was estimated as a low population density due to discontinuation of ecosystem and the man-made impacts. In this study, raccoon dog and water deer were selected as the target species because of their migration patterns and ecological value in local ecosystem. It was suggested to establish a wildlife corridors of an over-bridge type at the peak area of Galmachi, known to be the mostly-used migratory route for 2 target species.

Urban park and green space provide various functions. Among the functions, human benefit and increase of biodiversity are known to be important. Therefore, it is important to consider human and biotic aspect in the process of selecting suitable site for park and green space. However, there is insufficient research on both aspects. In this study, we used green network to analyze human and biotic aspect to select suitable site for park and green space in Seongnam City in Korea. To analyze the green network, we used accessibility for human aspect and used dispersal distance and habitat size for biotic aspect. We conducted least-cost path modelling using movement cost. In case of biotic aspect, GFS (generic focal species) is used to estimate habitat size and dispersal distance. To find out suitable site for park and green space, we used an overlay analysis method. As the result, old residential areas are shown have insufficient green network which needs park and green space. Furthermore, the green network for biotic aspect is insufficient in old residential areas comapred to green network for human aspect. The result of this study could contribute in planning of park and green space to maximize their functions.

유역에서 발생한 고탁수가 저수지내에서 장기화하는 현상에 관한 대책은 장기간이 소요되는 유역관리 대책과 탁수저감일수를 최소화하는 선택취수 개념의 우선 방류기법 등이 있다. 하류하천으로의 탁수 우선배제를 실시하기 위해서는 댐 방류탁수가 하류에 미치는 영향을 정확히 예측할 수 있는 하천탁도 예측 및 관리시스템 구축이 필요하다. 최근 고탁수현상을 경험한 낙동강 수계에서는 본류의 탁도 관리를 위해 임하댐 및 안동댐의 연직 탁도 분포 변화에 따라 댐 방류탁수에 의한 영향을 최소 또는 기준치 이하로 할 수 있는 댐 연계운영에 관한 조건 도출이 필요하다. 선택취수에 관한 수치모의 결과를 이용하여 저수지내 온도 및 탁도 분포 변화와 취수탑의 수문운영에 따른 방류수의 온도 및 탁도를 예측할 수 있다. 본 연구에서는 이와 같은 결과를 이용하여 안동댐과 임하댐의 방류조건에 대한 하류하천 합류부에서의 2차원 이송 확산 수치모의를 수행하고자 하였다. 이와 같은 연구를 성공적으로 수행하기 위해서는 지속적인 현장조사를 통한 지점별 탁도-SS 상관관계 도출, 비정상 흐름 및 수질모의 검 보정, 탁도예측 결과 검증이 필요하다. 평면 2차원 흐름 및 수질 모의 결과에 의하면, 임하댐 방류 탁도로 인한 반변천의 고탁수는 안동댐 방류 수에 지배를 받는 낙동강 본류와 합류되는 지점에서부터 약 5 km 떨어진 지점에서 횡방향 완전혼합이 이루어지는 것으로 나타났다. 이와 같은 모의결과는 완전혼합을 가정하는 1차원 수질모델링의 초기 입력자료에 사용됨으로써 1차원 탁도 모의결과의 정확성을 높이는 데 사용될 수 있다. 이를 이용하여 낙동강 수계 댐 연계운영에 따른 낙동강 탁도 예측모의를 수행하고, 이 결과를 이용하여 낙동강 탁도 예경보 시스템을 구축해야 할 것이다. 또한 선택취수 등을 통해 저수지 관리를 효과적으로 수행하기 위해서는 저수지 내부의 탁도 거동을 정확히 예측할 수 있어야 한다. 따라서 추후 동수역학 및 열역학에 기초한 3차원 수치모형 연구와 성층흐름에 정밀한 밀도류 실험연구 및 이에 대한 적용이 필요할 것으로 판단된다.
