Purpose: This study was conducted in order to present basic policy data for introduction of a home-based physical therapy (HBPT) policy. Methods: The study surveyed physical therapists and patients for six weeks, in order to identify satisfaction with physical therapy. The statistical significance of the management plan with regard to costs and cost estimation and payment methods was determined and managed according to the operating principals of HBPT, eligibility criteria, number of visits, treatment time, and team approach. Results: Through the survey all groups of patients and physical therapists recognized the need for HBPT. They felt that the most desirable methods for activation of physical therapy visits involve precise diagnosis and evaluation through a team approach. While making regular visits to the patient three times a week, an expert visiting physical therapist with 3 to 5 years of experience in the clinical field could provide central nerve developmental treatment in less than 60 minutes; this service could be provided at a reasonable cost, minimizing unnecessary hospital visits, reducing time, medical expenses and facilitating a quick recovery due to psychological satisfaction resulting from a decrease in the psychological anxiety patients often experience in medical institutions. Conclusion: Based on the study results provided above, if HBPT is to be introduced, appropriate pricing and programs should be based on the results of pilot projects.

This second consecutive research was connected to 7he previous first research with same title. The purpose of this research is to estimate the carrying capacity for the Seonjeong royal tomb and to propose its management planning. User's characteristics and relationship between user's density and vegetational environment were analized for the above objective. The result of this research shall be summarized as follows. 1. The site was damaged seriously by pupils and social groups'picnic activities concentrated in special periods of Friday and weekend during April and May. 2. Social-psychological carrying capacity estimation would be impossible due to lack of relationship between user's density and satisfaction. 3. Maximum user's density limits as a ecological carrying capacity was 1.4 persons per 100 square meters and modified optimum ecological carrying capacity was estimated as 1.0persons per 100 square meters. Maximum visitors as a optimum carrying capacity of the Seonjeong royal tomb area was estimated as 6,000 persons when supposing the proposed landuse planning. 4. To restore and preserve the tomb landscape as a traditional historic site, Seonjeong royal tomb shall be managed by three landuse areas ; protection and control area, natural picnic area and shaded picnic area. And the protection and control area include three sites ; natural reclamation site, natural preservation site and tomb landscape conservation site.

This study was carried out to estimate the recreation carrying capacity of lawn areas in parks. Recreation carrying capacity in this study is composed of two parts, ecological carrying capacity and psychological carrying capacity. As the second part, this apper deals with the estimation of ecological carrying capacity based on user behavior. The study sites were located at Bomun Resort Complex in Kyungju, Korea. And the major species of the lawn areas was Zoysia japonica. The major results ar summarized as follows: 1. The mean numbers of user for the investigation days of peak season, were estimated as 792 people for the lawn area of Doturag World, and 588 people for Seorabul Plaza. The mean use time by user were 163 minutes and 197 minutes for each site. The weighted mean use time by each activity type(passive, active, and strolling) were estimated as 85 minutes, 45 minutes, and 50 minutes, respectively. 2. Forty kinds of diverse active recreation activities were classified into six types of activity categories. Male adults preferred "sports type" activities, whereas female adults and juveniles preferred "play type" activities. 3. Ecological carrying capacity for each level was estimated as 40.7㎡/man for optimum carrying capacity. And these values were calculated on the basis of total treading areas and treading time criteria for each carrying capacity level.

Robots will be able to coexist with humans and support humans effectively in near future. One of the most important aspects in the development of human-friendly robots is to cooperation between humans and robots. In this paper, we proposed a method for multi-object identification in order to achieve such human-centered system and robot localization in intelligent space. The intelligent space is the space where many intelligent devices, such as computers and sensors, are distributed. The Intelligent Space achieves the human centered services by accelerating the physical and psychological interaction between humans and intelligent devices. As an intelligent device of the Intelligent Space, a color CCD camera module, which includes processing and networking part, has been chosen. The Intelligent Space requires functions of identifying and tracking the multiple objects to realize appropriate services to users under the multi-camera environments. In order to achieve seamless tracking and location estimation many camera modules are distributed. They causes some errors about object identification among different camera modules. This paper describes appearance based object representation for the distributed vision system in Intelligent Space to achieve consistent labeling of all objects. Then, we discuss how to learn the object color appearance model and how to achieve the multi-object tracking under occlusions.

본 연구는 운전 중 발생하는 청각 자극의 유형 및 정도가 운전자가 지각하는 주관적 속도감에 어떠한 영향을 미치는지를 알아보고자 수행되었다. 본 연구에서 사용된 청각 자극은 엔진 소음과 음악 소리였으며 전자는 자동차의 속도에 따라 함께 변하는 청각 단서인 반면 후자는 자동차의 속도와는 무관하게 변화하는 비단서 소음으로 사용되었다. 엔진 소음의 강도만 조작되어 제시된 실험 1에서는 엔진 소음의 크기에 따라 운전자가 느끼는 주관적 속도감이 다르게 나타나 운전자들은 엔진 소음이 작을수록 기준속도보다 더 빨리 주행한 반면 엔진 소음이 클수록 더 천천히 주행하는 것이 관찰되었다. 실험 2에서는 엔진 소음과 음악 소리를 모두 들려주었는데, 그 결과 엔진 소음의 크기변화에 따른 주관적 속도감의 차이는 여전히 나타났으나 음악 소리의 크기변화에 따른 속도감의 차이는 보이지 않았다. 또한 실험 1과 2를 통합하여 음악 소리의 유무효과를 분석해 본 결과 음악 소리가 엔진 소음을 차폐시킬 만큼 크고 엔진 소음이 작을 경우에는 음악 소리가 없는 경우보다 속도를 더 내는 것으로 나타났다. 이는 음악 소리가 속도감에 영향을 주는 직접요인은 아니지만 간접적으로 영향을 미친다는 가능성을 시사한다.

This study aims to derive the effect of road traffic noise perception by the visual and aural information through a laboratory experiment. To verify the result more precisely, ME(Magnitude Estimation) and SD(Semantic Differential Method) evaluation on the effect of visual and aural effect were carried out by 43 university students. As the result, up to 10% of psychological reduction effect was shown under the 65dB(A). As the noise level, it was analyzed that the vision affected about 7dB(A) and sound affected 5dB(A). However, if these two are given simultaneously, mainly sound affects to reduce the annoyance of noise and the vision next. Compared with the urban central circumstances, this effect(2dB(A) under 65dB(A) noise) was shown smaller than field test.

In this paper the failure possibility and the error possibility are used to represent reliability of a technical component and that of a human operator, respectively. The failure possibility and the error possibility are fuzzy sets on the interval [0,1]. In a man-machine system, reliability of the technical component and that of the human operator are usually affected by many factors, e.g., the environment in which a machine is operated, psychological stress of the human operator, etc. The possibility is derived from not only the failure or the error rate but also estimates of these factors. The fuzzy reasoning plays an important role in the derivation. The reliability analysis is performed by the use of the possibility obtained by the present method. Moreover this paper discusses the sensitivity analysis which evaluates what extent the change of the estimation of each factor has an influence on reliability of a man-machine system. The important factors to be ameliorated are shown through the sensitivity analysis.

This study aims to know the effect of road traffic noise perception when the visual and aural information is added in a laboratory experiment. ME (magnitude estimation) and SD (semantic differential method) evaluation on the effect of visual and aural effect were carried out by 43 university students. As the result, up to 10 % of psychological reduction effect was shown under the 65 dB(A). As the noise level, it was analyzed that the vision affected about 7 dB(A) and sound affected 5 dB(A). However, if these two are given simultaneously, mainly sound affects to reduce the annoyance of noise and the vision next. Compared with the urban central circumstances, this effect (2 dB(A) under 65 dB(A) noise) was shown smaller than field test.
