The purposes of this research were to investigate home care rehabilitation services in rural areas and to collect basic data about disabled persons necessary when for carrying out rehabilitation services. Respondents were selected from six of a total of eight townships (Myon) and one town (Eup) in the Wonju city area. Wonju is in Kangwon Province (Do). Of a total of 338 names provided by the Myon offices, 298 persons were located and included registered and non-registered persons. Conditions included stroke, spinal cord injury, and cerebral palsy in addition to disabilities classified as first, second or third degree, in the case of registered cases. Respondent demographic characteristics, medical characteristics, rehabilitation service needs, willingness to receive rehabilitation service and individual opinions regarding rehabilitation services were analysed by frequency and percentage. The results were as follows: 1) Rehabilitation services received by disabled persons living at home in the rural areas surrounding Wonju city were medical rehabilitation (41.7%), diagnosis (36.5%), rehabilitation assistive devices (7.6%), social assistance (7.1%), rehabilitation counseling (3.0%), vocational rehabilitation (1.8%), educational rehabilitation (1.6%) and housekeeping services (0.5%). The majority of rehabilitation services were medical rehabilitation provided at hospitals and oriental medicine hospitals. 2) Sixty point eight percent of respondents expressed their willingness to receive home care rehabilitation services. Needs expressed were highest for medical rehabilitation (27.0%), followed by social assistance (19.4%), medical examination (12.4%), physician-generated diagnosis in the home setting (11.6%), sociopsychological rehabilitation (9.3%), vocational rehabilitation (7.6%), rehabilitation engineering (6.0%), educational rehabilitation (3.3%), and housekeeping services (3.3%). 3) Rehabilitation service needs were analyzed by severity classification: 65.8% of first degree, 62.7% of second degree and 55.6% of third degree disability classification, and 62.7% of non-registered disabled individuals responded that rehabilitation service was necessary. 4) Rehabilitation service needs were also analyzed by diagnosis: 62.6% of stroke, 85.5% of amputation, 60.0% of spinal cord injury and 52.4% of traumatic brain injury respondents answered positively that they were willing to receive rehabilitation service if it were to be provided. Rehabilitation service utilization data of disabled individuals living at home in rural areas were investigated and their rehabilitation needs analyzed. This critical information can be used when community-based rehabilitation programs for disabled persons living at home are planned for provision out of a public health center or when community-based rehabilitation welfare policy is formulated.

The purpose of this study was to compare the balance and gait between fallers and non-fallers in elderly. A brief questionnaire was used to obtain the fall history. Twenty-seven women subjects were evaluated in this study. Eleven subjects and a mean age of 84.5 years (SD=4.6) were designated as the faller group. Sixteen subjects and a mean age of 80.3 years (SD=5.3) were designated as the non-faller group. The fall-related factors (mental status, balance, range of motion and muscle strength of lower extremity, sensation of foot, and cadence, walking velocity, stride length) were compared between faller group and non-faller group and measured. The results showed that faller group had significantly less range of motion of the hip flexion and knee extension, and strength of the knee extensor and ankle dorsiflexor and plantar flexor than non-faller group. The scores of the Functional reach test and One leg standing were significantly less in faller group than in non-faller group. Faller group showed less walking velocity and stride length compared to non-faller group. However, there was no significant difference in cadence during comfortable waking and fast walking between two groups. There were no significant differences in pressure, position sensory between two groups. These results suggest that exercise for improving the flexibility, muscle strength of the lower extremity and balance may be useful strategies to prevent fall in elderly. Further studies are needed to identify which specific factors are related to fall in the elderly population.

Traditional Korean beverage can be divided into Jang, Gahl Soo, Mi Su, Soo Jung Gwa, Shick Hae, Tahng, Hwa Chae, Sook Su, and Tea according to ingredients and how it is proccessed. The purpose of this study was to investigate the Korean beverage percetpion and to analyze the factors (sociodemographic factors and life-style related factors) which influence percetpion of Korean beverage. Questionnaries were hand delivered to 2,200 subject residing in Seoul and 1,884 questionnaris were collected : resulting in 84% response rate. Statistical data analysis was completed using SAS Package program for the analysis of covariance(ANOCOVA).The results are as follows: (a) Survey on Korean beverage perception showed that the recognition rates of ShickHae(58.4%), Cition Tea(53.5%), Sung Nung(48.7%) and Soo Jung Gwa(40.8%) were high, whereas those for Tahng, Jang, and Gahl Soo were low.(b) About 40% of respondents performing 4 kinds of Korean traditional ceremony a year The percentage that reported they purchased Korean beverages was 44.0%, higher than the 38.5% that answered they made Korean beverage at home.(c) In analyzing the factors which influence beverage perception, the sociodemographic factors variously influenced perception rate depending on beverage. Age and sex had influenced on perception rate of Shick Hae and Donggulre Tea. Income level influenced on the perception rate of Sung Nung and Citron Tea. Sociodemograhpic factors like senior over 50s, female and extended family size had positive influence on the perception rate.

켐크리트 개질 아스팔트 혼합물은 산소와 고온의 온도조건에서 급속하게 경화된다. 켐크리트 개질 혼합물을 아스팔트 포장의 표층에 적용할 경우 이러한 과다한 경화로 인하여 조기 균열이 발생되기도 한다. 이러한 조기 균열의 발생을 완화하기 위하여 켐크리트 개질 혼합물을 아스팔트 포장의 기층에 적용하고 있다. 본 연구에서는 켐크리트 개질 아스팔트와 혼합물의 공용성을 규명하기 위하여 아스팔트 바인더에 대해 동적유동시험 및 처짐보유동시험 등을 실시하였고 혼합물에 대한 일축인장 피로 및 휠트래킹, 수분손상 시험 등을 실시하였다. 또한 현장에서 채취한 시편에 대해 회복탄성계수시험을 실시하여 일반 및 켐크리트 개질 혼합물의 강성을 비교분석하였다. 이상의 시험결과로부터 켐크리트 개질 혼합물은 일반 혼합물에 비해 소성변형에 대한 저항성이 크다는 것을 알 수 있었다. 그러나 켐크리트 혼합물이 추운지방에 사용될 경우 저온균열의 문제가 발생할 가능성이 있을 것으로 사료된다. 켐크리트 혼합물을 기층에 적용하여 2년 이상 경과한 경우 켐크리트 개질 혼합물은 일반 혼합물에 비해 강성이 약 50% 정도 증가됨을 알 수 있었다.

온실의 차광설계에 필요한 기초자료를 제시하기 위하여 온실모형과 실험온실을 이용하여 외부차광재의 적정 설치간격 분석, 차광재별 광투과율 분석, 차광율에 따른 온실내부온도의 변화 분석, 차광의 온실내부의 지온변화에 미치는 영향 분석 및 외부차광과 내부차광의 차광효과 비교를 실시하였다. 외부경사차광시 온실 지붕과 차광재의 설치간격은 10~30 cm에서 차광효율이 가장 좋은 것으로 나타났으나 환기창의 개폐를 위한 공간이 필요하지 않는 온실에서는 10cm 정도이면 충분한 간격이 될 것으로 판단된다. 경사차광의 온도차가 수평차광보다 높게 나타나 무환기 상태에서는 경사차광의 차광성능이 수평차광보다 더우수함을 알 수 있었다. 차광재 제작사에서 제시한 투과율과 실제 온실에서 계측한 투과율이 상당한 차이가 있으므로 차광재를 온실의 온도환경제어 목적으로 이용하고자 할 경우에는 차광재의 투과율을 미리 측정하여 검증할 필요가 있었다. 자연환기와 무환기 조건 모두에서 85% 차광온실이 55%차광온실 보다 최대 약 4℃, 평균 약 2℃ 정도의 승온억제효과가 더 있었다. 차광온실 내무의 지온변화는 차광율과 차광방법에 따른 차이는 매우 작았으나 무차광온실과는 큰 차이가 있었기 때문에 온실내부의 지온변화는 차광율과 차광방법 보다는 차광의 유무에 큰 영향을 받는다는 사실을 알 수 있었다. 50%인 차광재가 55% 차고아재보다 광투과율이 높음에도 불구하고 차광율 50%인 외부차광온실이 차광율 55%인 내부차광온실보다 승온억제효과가 더 우수한 것으로 분석되었다. 이러한 결과는 외부차광시 차광재가 흡수한 열이 온실내부로 전달되지 않을 뿐만 아니라 천장을 통한 환기효율이 내부차광보다 양호하기 때문인 것으로 판단되었다.

In the last year, the number of registered vehicles in Korea surpassed the 12 million mark, and increase in number continuously Nowdays, this tendency has raised some problems inevitably in the view of expansion of ELV(end of life vehicle) and earth environment pollution resulted from it. For the proper scope with this environment pollution, recycling of parts and materials, minimization of wastes are desirable. And application of disassembly technology is required for it necessarily. Therefore it is essential to study systematically about disassembly technology of ELV with high efficiency for improvement recycling ratio and diminution shredder dust amount also in Korea.

Many production management systems for increasing productivity, minimizing inventory, keeping due dates and maximizing use of resources have been proposed, and GT, MRP and JIT are frequently used among these systems. The three systems have merits and demerits through comparing with each other. Because each system has mutual dependence, a hybrid production system is necessary for using their merits maximally. In this study, a hybrid production system is designed by combining GT, MRP and JIT, which is suitable in the domestic production system.

WO3에 NiO를 첨가하여 제조한 후막형 시편의 미세구조와 전기적 성질에 대해 연구하였다. NiO 첨가에 따른 WO3의 결정립 성장이 억제되었고, 입도 분포도 균일하였으나 첨가량에 따른 결정립 크기 변화정도는 작았다. 산소 분압 감소로 WO3의 전도성은 증가하였고, NiO 첨가에 의해 고용한계 이하에서는 전도성이 증가하였고, 이상에서는 전도성이 감소하였다. 온도 증가에 따라 외인성 (extrinsic) 구간에서는 전도성 변화가 적었고, 고온의 진성 (intrinsic) 구간에서는 전도도가 급격히 증가하였으며, 이들의 중간 온도에서는 산소흡착에 따라 전도도가 감소하였다.
