Purpose: This study examined the effects of spinal stabilization exercises using visual feedback on the gross motor function and balance of the sitting posture in children with cerebral palsy. Methods: The subjects were 18 children with cerebral palsy aged 8-15 years in the I-III stages of the Gross Motor Function Classification System. The subjects were divided into an experimental group (n=9) and control group (n=9). The experimental group was treated with 30 minutes of neurodevelopmental treatment and 20 minutes of spinal stabilization exercises using visual feedback. The control group was treated with 30 minutes of neurodevelopmental treatment and 20 minutes of spinal stabilization exercises without visual feedback. Both groups participated in the experiment twice a week for eight weeks. The Gross Motor Function Measurement was performed to evaluate the changes between pre- and the post-intervention in gross motor function. The Seated Limit of Stability Surface Area was measured to evaluate the changes in trunk balance. Results: Both experimental and control groups showed a significant increase in the gross motor function and trunk balance (p<0.05). The experimental group showed a significant increase in gross motor function compared to the control group (p<0.05). The experimental group showed a significant increase in the dynamic trunk balance in all directions when measuring the Seated Limit of Stability Surface Area (p<0.05). Conclusion: Spinal stabilization exercises using visual feedback for the neurodevelopmental treatment of children with cerebral palsy can improve their gross motor function and trunk balance when in a sitting posture more effectively.

We propose a method of surface extension method using several functions. Interpolation theory is well developed in curve and surface. But extrapolation theory is not well developed because it is not unique outside the useful domain. It requires continuous, first derivative, second derivative continuous extension for matching in NC(Numerical Control) machine. In the past, we generate data outside the useful area and refit those data using least squares method. this has some problems which have some errors within the useful area. We keep the useful area and extend the unuseful area by a function

An optimization approach is used to solve the division problem of working area, and a cost function is defined to represent the constraints on the solution, which is then mapped onto the Hopfield neural network for minimization. Each neuron in the network represents a possible combination among many components. Division is achieved by initializing each neuron that represents a possible combination and then allowing the network settle down into a stable state. The network uses the initialized inputs and the compatibility measures among components in order to divide working area.

The objective of this study is to analyze the propriety of the Biotope Area Factor's(BAF) application and propose an improvement plan. The BAP system, initially started by Seoul metropolitan city, is being settled in Korea. The BAF originated from the Biotop $Fl{\ddot{a}}chen$ Faktor(BFF) system of Berlin Germany. It was established as part of the Landscape Plan for the ecological function recovery in the high density built-up area with a sense of environmentally friendly urban management. The study compared the BAF's present condition of Ganddong-Gu, Seoul with Seoul's BAF system. Some problems appeared from the system application. Firstly, it may cause ecological damage if the site ranges are more than current BAF system limits. Secondly, the application of the current BAF system has the possibility of general redevelopment, but the partial improvement considering current standards of the high density built-up area's paving section is impossible. Lastly, division of the application object and application type are not divided well. In addition, the Seoul BAF which is currently applied across the board is based on the destruction of the natural area and low density built-up area. Accordingly, to improve these problems requires a complementary system protecting the ecological function prior to the application of the BAF and with restricted application to high density of BAF system built-up area.

산림녹지의 기능평가에 대한 많은 연구들이 도시민의 이용적 관점에 치중되어 있으며, 자연생태학적 관점에서 종합적인 기능을 평가한 사례는 미흡한 실정이다. 이에 본 연구는 산림녹지에 대한 지속적인 계획 및 관리를 위한 기초 연구로서 산림녹지의 자연생태적 기능에 대한 평가 지표 선정 및 적용을 목표로 하고 있다. 우선, 국 내외 56개 문헌 조사를 통해 최초 35개 지표를 선정되었고, 1차 설문에 의해 12개의 자연생태적 지표가 선택되었으며, 2차 설문에 따른 MCB분석에 의해 녹지면적, 녹지연결성 등 7개 지표가 최종적으로 결정되었다. 또한, 3차 설문에 따른 AHP분석에 의해 7개 지표에 대한 가중치를 설정하여 기능 평가를 기초 작업을 완료하였다. AHP분석 결과에서는 자연성 항목이 0.189로 가장 높게 나타났으며, 반면 식생활력도가 0.063으로 가장 낮게 평가되었다. 사례지 적용을 위해 대구광역시를 대상지로 설정하여 산림녹지에 대한 자연생태적 기능을 평가한 결과, 앞산과 청룡산, 비슬산의 정상부를 따라 85점 이상의 높은 점수가 나타나 자연생태적 기능이 우수한 지역으로 평가되었다. 반면, 와룡산과 마천산의 서쪽지역, 달성군의 대니산 일대지역에서 50점미만의 낮은 점수가 나타나 지속적인 관리가 필요한 지역으로 평가되었다. 이상의 평가 지표 및 결과들은 향후 도시계획, 환경계획을 수행함에 있어 보전 및 관리를 위한 기초 자료로 활용될 수 있을 것으로 판단된다.

Development restriction areas (greenbelt areas) of Korea were recognized in 1970 as a means to control urban sprawl and conserve the natural environment. Although there have been some achievements, for a long time many planners and residents have requested a redefining of the green belt due to individual property rights restrictions and urban management problems. In fact, a lot of the greenbelt area is being destroyed by urban development. Therefore, conservation of ecological spaces in the green belt is needed to maintain urban naturalness. In this regard, this study suggests efficient methods to manage the greenbelt through the adoption of a landscape ecological value assessment. The greenbelt of the Seoul Metropolitan Area (SMA) is represented as the case study because there has been mounting pressure to develop the area in Korea. In this study, the assessment of the landscape ecology in the greenbelt area focuses on landscape structure and function. The assessment consists of the following steps: First, patches were derived by NDVI analysis using landsat remote sensing data. Second, characteristics of the patches were quantified by analyzing the landscape structure, such as patch size and shape index. Lastly, the gravity model and least cost path analysis to assess connectivity were applied to evaluate the landscape function in the green belt areas. The assessment result showed that 48.45% of green belt area should be conserved to maintain ecological stability and function. Moreover, major ecological networks were identified near the large patches in the northern and southern areas. However, relative low ecological values were identified in the western part of the green belt area due to the lack of green spaces. Furthermore, some development plans in the green belt were also identified near the conservation area. Based on these results, the restoration needed areas to enhance ecological value in green belt were displayed. This study suggests efficient management of the greenbelt area, which is disappearing as a result of urban development. The area for conservation chosen in this study should be managed carefully in urban planning. Finally, the results of this study can be used in green belt polices and plans for the promotion of ecological naturalness and stability.

Museums after '70's shows remarkable development in public area as well as exhibiiton area. One of the main changes in recent museums is to extend the concept of circulatin area, which regarded solely as a corridor connecting exhibition areas, as a multiple function area with various service facilities. This study aims to outline atypological classification of exhibition area considering with circulation area in museum. On the base of two principal types of exhibition area, that is room type vs open plant type, 30 representative worldwide museums are analyzed and four different types are identified as a result. 1) Loop type as a rotating structure of serial exhibition rooms 2) Cluster type which produce complicated circulation with rooms lied one upon another 3) Centrum type which is specially available to multistory exhibition area 4) Loft type with maximum flexibi쇼 and accessbility.

This study aims by analysing the interior design elements trends of current medium size office buildings in Seoul. The analysing objects are ceiling, floor, wall, and illumination plan of current office buildings. Analysing tools are finishing material and color of each part. Analysing areas are lobby area, deskwork area, conference area, welfare area, public area(rest room, corridor, stair). The interior design elements of lobby shows a lots of different features then the other areas in ceiling, floor, and wall design. Such difference appears at finishing material especially, and the coloring is more splendorous then the other areas. Desk work area and conference area have similar characteristics in finishing materiors and colors, and they usually follow the needs of function. Walfare area shows more splendorous feature then deskwork and conference area, and designed by various materials and colors. Public area also shows very active design concept then past times.
