Well planned rehabilitation order of pipes is essential for efficient maintenance and management of Water Distribution Systems. In this study, not only deterioration rate of pipes but also structural and nonstructural failure which causes abnormal condition of WDS is considered to determine rehabilitation order. Probabilistic Neural Network is used for calculating deterioration rate at present and the importance of pipes is computed under structural and nonstructural failure by using Pipe by Pipe Failure Analysis and Effect Index. Utopian Approach, one of the Multi-Criteria Decision Making methods, is used for assessment of final rehabilitation order based on distance measure between utopian point and alternative one. Developed model in this study shows that it gives more reliable results than existing methods considering hydraulic relative importance does in application to real networks. In this point, the newly developed model, which gives advantages over existing models, can make a credible decision and simple application.

본 연구에서는 재활정도를 정량적으로 표현하기 위하여 정상 보행과 모의 비정상 보행 시 보행주기에 따른 근전도 패턴에 고차 곡선 맞춤을 적용하여 분석하였다. 보행 근전도 패턴에 적합한 다항식을 생성하였으며, 그 변수를 군집분석 하여 5개의 그룹으로 분류하였다. 정상패턴을 포함한 그룹을 기준으로 거리가 가까운 그룹을 나열하여 각 변수의 분포를 확인하였다. 진폭감소 패턴, 불규칙 패턴, 역상 패턴 순으로 정상 패턴에 유사하였으며, 분류된 그룹의 분포는 중첩되는 범위가 작아 변수 값을 이용한 그룹 분류가 가능하였다. 분류된 재활정도를 정량적으로 나타내기 위하여 각 계수항의 표준편차를 패턴별로 비교하였고, 정상에 가까울수록 큰 값을 가지는 것을 확인하였다. 역상 패턴의 경우는 편차 값은 크지만 부호가 음의 값을 가지므로 가장 작았다. 본 연구의 결과인 정량적인 재활정도의 표현은 보다 효율적인 재활방법 연구에 기여할 것으로 예상된다.

Stroke is known as a detrimental disease that leaves serious sequelae. The stroke patients suffer from limitations of physical and social activities. The patients try to adapt themselves to the limitations in order to achieve rehabilitation. This study was performed to clarify the lived experience of rehabilitation from the stroke patients. In collecting data for this study, in-depth personal interviews were made by a researcher from February to April in 2001 at rehabilitation clinics and physical therapy centers locate in Iksan city. The methodological approach was van Manen's hermeneutic phenomenological methodology in order to understand the meaning and nature of stroke patients' experiences in rehabilitating their physical limitations. Collected data were analyzed with phenomenological way of study that was develope by van Manen. The 8 patients who agreed to participate in this research were inter viewed by researcher under the private and comfortable environment. Personal interviews were done three or five times per each patients and each interview took 70 to 90 minutes. The statements were analyzed and finally revealed three essential themes : Theme 1 - Desperateness to achieve freedom again Theme 2 - Seizing hope of recovering Theme 3 - Seeking support from family members, relatives and friends Based on these themes, stroke patients' rehabilitation experience are described as following. The stroke patients have strong desire to achieve freedom again in order to escape from social isolation. The stroke patients want to go back to the state of their previous health state. The stroke patients strongly try to do anything for their recovering and also to have positive thinking. In the other hand, they feel pity for themselves through desperation, fear, sorrow, and self-pity. The stroke patients have dissatisfaction about neighbors' rumor and attitude toward themselves. The stroke patients have experiences to rely on neighbors' support seeking a warm word of consolation. This research showed us that van Manen's hermeneutic phenomenological methodology leads us to understand stroke patients' rehabilitation process more comprehensibly. Based on this research, it is suggested that further studies provide a foundation for the development of a rehabilitation theory for Korean stroke patients.

Purpose: For patients with CNS injury who are restricted in the use of public transportation, car driving means more than simple movements and is essential for their independent lives, such as participation in society and returning to jobs. Therefore, in order to enhance the quality of life of disabled persons, their high perception and necessity of driving rehabilitation are required. The purpose of this study is to determine the perception and necessity of driver rehabilitation in patients with CNS injury. Methods: In order to survey the perception of patients with CNS injury and necessity of driving rehabilitation, questionnaires were distributed to patients with CNS injury. Questionnaires were composed of demographic characteristics, disability related characteristics, and driver's license related characteristics. Results: Our results showed that the number of driving participants with a driver's license for the disabled was significantly higher than that for non- driving participants with a previous general driver's license in the perception of driving rehabilitation. Conclusion: We suggest that driving rehabilitation for patients with CNS injury should be supported in terms of evaluation and treatment.

하수관거시스템 개량의 주된 목적은 불명수(Inflow/Infiltration, I/I)를 제거함으로써 그 성능을 향상시키는데 있다. 이때 전체 하수관거시스템 내에서 개개 관거별 I/I 발생량을 정량화할 수 있다면, 전체 하수관거시스템 내에서 소유역별 해당 정보의 추출이 보다 명확해질 수 있다. 그러나 실제 현장에서는 예산 및 시간의 제약 때문에 개개 관거의 I/I 발생 정보의 획득은 거의 불가능하다. 본 연구에서는 하수 관거별 I/I 발생량을 AHP(Analytic Hierarch Process)를 이용하여 정량화하였으며, 산정된 관거별 I/I 발생량을 이용하여 효율적인 하수과거 개량 사업 시행을 위한 개량 우선순위 결정 모형(Rehabiliation Priority Decision Model for sewer system, RPDM)을 개발하였다. 개개 관거별 I/I 발생량 산정 결과에 기반하여 RPDM은 개량이 시행되는 기간 동안 발생하는 I/I 발생량을 최소화하는 소유역별 최적 개량 우선순위(Optimal Rehabilitation Priority, ORP)를 유전자 알고리즘을 이용하여 결정한다. 이때 최적 개량 우선순위에 따른 소유역별 개량 시행 시 발생하는 이익은 개량 기간 동안 하수처리장으로 들어가는 I/I의 하수처리비용(Waste Water Treatment Cost, WWTC)에 대한 절감을 의미한다. 본 연구에서는 개발된 RPDM에 의한 최적 개량 우선순위의 결과는 일반적인 하수관거 개량사업의 우선순위 결정 방법인 점수가중평가법(Numerical Weighting Method, NWM)과 최악의 개량순서에 따른 결과들과 비교되었으며, 개량 기간 동안의 I/I 처리비용이 점수가중평가법에 비하여 22%, 최악의 개량순서에 비하여 40% 감소하는 것으로 나타났다.

For the self-directed rehabilitation of upper extremity hemiplegia patients, in this paper we propose an interface method capable of doing bilateral exercises in rehabilitation robotics. This is a method for estimating information of movements from the unaffected-side, and projects it to the affected-side in order. That the affected-side is followed the movements of the unaffected-side. For estimation of the unaffected-side movements information, gyro sensor data and acceleration sensor data were fused. In order to improve the measurement error in data fusion, a HDR filter and a complementary filter were applied. Estimated motion information is derived the one side of the drive input of rehabilitation robot. In order to validate the proposed method, experimental equipment is designed to be similar to the body's joints. The verification was performed by comparing the estimation angle data from inertial sensors and the encoder data which were attached to the mechanism.

This study evaluated the community-based rehabilitation services provided by the Wonju Public Health Center from Jan. 2000 to Dec. 2002. Ninety-four persons with disabilities dwelling in the community participated and the surveys were completed in an interview during home visits. The respondents' demographic, socio-economic, and medical characteristics, rehabilitation service received, willingness to receive home-visit rehabilitation services, and satisfaction with the rehabilitation services were analyzed by frequency and percentage. A Likert scoring system consisting of five agreement-disagreement categories was applied to each item, consisting of Very Satisfied, Satisfied, So-So, Poorly Satisfied, and Very Poorly Satisfied. The major findings were as follows: 1) The rehabilitation services used included medical rehabilitation (26.9%), followed by social assistance (23.5%), diagnosis by a physician at home (17.3%), medical examination (12.3%), housekeeping services (6.2%), and vocational and educational rehabilitation (3.5%). 2) Of the medical services, the respondents desired physical therapy at home and free rental of rehabilitation equipment, such as wheelchairs, canes, walkers, the most, followed by home visit occupational therapy, nursing services, and oriental medicine service in descending order. 3) Some of the respondents expressed so-so satisfaction (50.0%) or dissatisfaction (16.9%) with the rehabilitation services provided by the Wonju Public Health Center. These findings should prove useful when planning or extending community-based rehabilitation programs for the homebound disabled in the community.
