The purpose of this study was to identify the effects of an upper extremities group exercise program based on motor learning in chronic stroke patients and to assess improvements in upper sensory motor function and activities of daily living (ADL). Five chronic stroke patients participated for the duration of 25 weeks. On the assessment of motor and process skills, there was a statistically significant improvement in motor area functioning in 4 of the subjects. In process area functioning, there was a statistically significant change in 3 of the subjects. Therefore, further studies are needed to assess sensorimotor area and ADL changes in chronic stroke patients to reduce medical cost and assess for positive psychological changes.

This paper suggests improvements in travel cost function of transit assignment model by analysing existing model. Two types of travel cost function are widely used for congested public networks. The one is used for strictly restricting public transport capacity. Another is non-decreasing function such as BPR function. In this paper, we analyse two types of travel cost function in case of intercity rail. The characteristics of intercity rail are different from those of public transit in urban area. Therefore travel cost function must be differently applied in each case.

This article assumes that the first newtown has declined in Korea. Urban regeneration projects should be implemented for regeneration for CBD in Newtown as well as small local cities. The purpose of this article is to analyze the character of the subway area and to suggest the key issues for regeneartion in the subway area. Especially focussing on the local important commercial function in 5 subway areas. As a result of analyzing 5 subway areas according to basic statistical data, field interviews, and legal decline diagnostic index, all five commercial districts showed decline. In particular, the decline of Baekseok Station area appears to be serious, and there is a key factor that attracts the decline of the commercial area such as the long - term building or the closure rate of each commercial area. In addition, the vacancy rate is increasing due to large distribution facilities in new cities, the entry of new floating facilities on the outskirts, and unsold new stores, and the recession is accelerating. In this way, the signs of decline in the core of the new city are enriched, but the current Urban Regeneration Act is a legal system with a policy goal of regeneration of small and medium cities in the provinces as a system to promote the function of core bases rather than the overall redevelopment of new cities. Therefore, preemptive response is needed for the regeneration in those areas.

A potential field method for solving the problem of path planning based on global and local information for a mobile robot moving among a set of stationary obstacles is described. The concept of various method used path planning is used design a planning strategy. A real human living area is constructed by many moving and imminence obstacles. Home service mobile robot must avoid many obstacles instantly. A path that safe and attraction towards the goal is chosen. The potential function depends on distance from the goal and heuristic function relies on surrounding environments. Three additional combined methods are proposed to apply to human living area, calibration robots position by measured surrounding environment and adapted home service robots. In this work, we proposed the application of various path planning theory to real area, human living. First, we consider potential field method. Potential field method is attractive method, but that method has great problem called local minimum. So we proposed intermediate point in real area. Intermediate point was set in doorframe and between walls there is connect other room or other area. Intermediate point is very efficiency in computing path. That point is able to smaller area, area divided by intermediate point line. The important idea is intermediate point is permanent point until destruction house or apartment house. Second step is move robot with sensing on front of mobile robot. With sensing, mobile robot recognize obstacle and judge moving obstacle. If mobile robot is reach the intermediate point, robot sensing the surround of point. Mobile robot has data about intermediate point, so mobile robot is able to calibration robots position and direction. Third, we gave uncertainty to robot and obstacles. Because, mobile robot was motion and sensing ability is not enough to control. Robot and obstacle have uncertainty. So, mobile robot planed safe path planning to collision free. Finally, escape local minimum, that has possibility occur robot do not work. Local minimum problem solved by virtual obstacle method. Next is some supposition in real living area.

Purpose: Korea is increasing in the demand for medical services due to rapid economic growth and population aging in modern society. Thus, the importance has been emphasized for the health promotion in the community and the publicity and substantiality of public health centers. However, the environment is insufficient, compared to required functions and developed services as a urban public health center. The purpose of this study is to analysis the plane type and area composition of public health centers in Busan and to identify the property of their spatial configuration Methods: Eight public health centers in Busan, were classified, which had been selected as a medical tourism city. Subsequently, space requirements were analyzed, facilities were typed, vertical, horizontal spaces were reviewed, and area ratios by business function were calculated. Results: A review of the property of spatial configuration and an analysis of the area ratio revealed the three findings. 1)The horizontal analysis found various types: a single type, a multi-type, a radial type, and a circular type, 2)The vertical analysis showed that since a care function (general practice), and a task function (maternal and child health) were concentrated in lower level spaces, the lobby and core were closed located for providing quick medical services. 3)The analysis of the area ratio in public health centers in terms of their function indicated that each public health center' programs had the greatest influence on the area. Implications: This study attempted to present spatial structural problems and improvements for city public health center by identifying their state and classify their functions and types and by calculating the ratio of their area configuration according to the spatial composition. It was thus aimed to presenting implications in establish public functions and roles by activating business through in connection with the number of municipalities in many ways, such as regional health. medical welfare, etc. to improve the health of local residents, and by providing differentiated programs in accordance with local characteristics.

The purpose this study was to investigate the relationship between Upper extremity's function and Activities of Daily Living(ADL) in stroke patients. The participants were 112 stroke patients who underwent occupational therapy. Data were analyzed using descriptive statistics, Pearson's correlation coefficient, and multiple linear regression analysis. The results are as foolows. MFT of both unaffected upper limbs and affected upper limbs were significantly correlated with total MBI score. The all area of MFT on the affected upper limbs were significantly correlated with sub-item of MBI. And finger manipulation area of MFT on the unaffected upper limbs were significantly correlated with sub-item of MBI. Significant factors influencing MBI, both unaffected upper limbs and affected upper limbs total score. Significant factors influencing sub-items of MBI, the function of affected upper limbs by MFT were MBI all sub items exculsive bowel, bladder control and the function of unaffected upper limbs by MFT were personal hygiene, bathing, feeding, toilet, bowel & bladder control, chair/bed transfer of MBI sub items. Above results show that ADL is highly correlated with affected upper limbs and unaffected upper limbs function in the stroke patients.

현재 우리나라의 설계속도는 도로의 기능, 지역특성, 지형에 의해 결정하도록 규정하고 있다. 그러나 도로의 기능을 구분하는 뚜렷한 기준이 없어 적정 설계속도 결정에 설계자의 주관이 개입될 여지가 많으며, 기능분류가 단순하여 설계에 반영되지 못하는 도로기능이 존재하고, 지역분류기준 또한 모호하여 주변지역의 토지이용 특성을 제대로 반영하지 못하였다. 한편 도로가 통과하는 지역의 지형적 특성을 충분히 고려치 않고 단순히 교통소통 만을 강조하여 지나치게 높은 설계속도로 설계하여 도로의 건설비가 증가하고 있다. 따라서 본 연구에서는 지방부 도로 기능분류 및 설계속도 결정에 계획교통량 규모를 반영토록 하여 설계자의 주관적 판단소지를 줄이고 경제적 효율성을 기하였으며, 도시부 기능을 세분화하여 기능분류의 단순함과 설계에 반영되지 못하는 도로의 기능이 존재하는 문제를 해결하였다. 또한 GIS의 지형고도 데이터를 이용하여 지형을 구분하는 구체적 기준을 제시하였다. 즉 기능, 지역, 지형요소를 보다 세분하여 고려하고, 보완기준으로 계획교통량을 추가한 새로운 기능분류와 설계속도 결정기준을 제시하였다.

인터넷에 의해 도래된 네트웍 사회는 물리적 공간이 아닌 사이버 공간이라는 새로운 공간을 인간에게 제공하였다. 그러나 현재는 사이버 공간에서 순기능이 아닌 역기능이 사회적 문제로 대두되고 있다. 구체적으로 말해 청소년 등이 음란 외설이나 폭력 같은 불건전한 정보의 무분별한 접속에 따른 윤리 교육에서부터 시작해서 국적 불명의 단어와 기호 등을 조합하여 사용하는 e-mail 그리고 인터넷 자유게시판에서 상대방에 대한 성적 모독, 욕설, 상대방 비하, 근거 없는 비방 등과 같은 인터넷 역기능에 대한 문제가 이슈가 되고 있다. 그 뿐 아니라, ID나 패스워드 등을 도용한 불법 엑세스도 만연하여 이를 해결키 위한 기술적 방법이 강구되지 않으면 사이버 범죄에 따른 피해가 대단히 클 것으로 여겨진다. 본 논문에서는 이 같은 인터넷 역기능에 대처키 위한 동향 등을 살펴보고 특히 인터넷 자유게시판에서의 적절한 운영 방안 등에 대해 논하고자 하며 이를 퍼지 의사 모델에 의해 검토하기로 한다.

1974년 한강홍수예경보시스템을 구축한 이후로, 저류함수법을 근간으로 하는 홍수예경보시스템이 주요하천을 대상으로 운영되고 있다. 1961년 목촌릉황(木村俊晃)에 의하여 제안된 저류함수법은 저류함수를 기본식으로 이용하고 있다. 저류함수법에서는 유역을 유출역과 침투역으로 구분하고, 누가우량이 포화우량을 초과하기 전까지는 유출역에서만 유출이 발생하고, 포화우량을 초과한 후부터 침투역에서도 유출이 발생하는 것으로 가정하였고, 이때 유출역의 면적이 일정하므로 유출률은 일정한 것으로 가정하였다. 또한 유출역과 침투역의 유출량을 분리하여 계산하며, 이는 비선형저수지의 특성을 고려하면 불합리하다. 본 연구에서는 저류방정식과 연속방정식을 이용한 수정저류함수법을 제시하였으며, 유효우량은 SCS 초과우량산정방법을 이용하였다. 낙동강유역의 위천을 대상으로 수정저류함수법을 적용하였으며, Kimura 저류함수법에 비하여 첨두홍수량 산정에 개선된 결과를 보였으며, 매개변수의 감소로 적용성을 개선하였다.
