In ubiquitous spaces, a user wants to be provided with a VOD service while moving one space to another freely. Since the traditional VOD system is dependent on user location, the VOD server transmits video data to a single client during a session. If the user moves to another space, he/she should close the old session and make a new request for the same video. However, the location-aware VOD system supports user mobility by closing and opening the session automatically. That is, the VOD system automatically perceives the movement of a user and allows the server to change the data flow so that a client near the user can receive the video data. This paper proposes a location-aware VOD service architecture and a session handoff scheme to provide a mobile user with continuous video delivery and implements a location-aware VOD prototype system based on Jini and Java. In experiment, we show that the proposed handoff scheme has a smaller handoff delay than the other handoff scheme.

Pyeongtaek is one of the most dynamic and fastest growing cities in Korea. It is expected that Pyeongtaek will be fostered as one of the most technologically advanced cities with over one million residents in ten years, in transit from the current status of an urban and rural multi-functional city. As a consequence of the change, it is also anticipated to embrace problems related to environmental pollution. The current study investigates perceptions and attitudes of Pyeongtaek citizens towards the natural environment and the conservation of nature. A survey of the environmental perception was conducted with 700 people from the city. The data was analyzed by SPSS 12.0. Findings of the survey demonstrate that Pyeontaek citizens, overall, are interested in environmental issues; they also expect the city to be prosperous without nature destruction. Based upon the results, the study describes the current status of the areas which the citizens consider as most crucial; further, it makes practical suggestions for ways of conserving the environment for the future.

The originator of the proprioceptive neuromuscular facilitation method was Dr. Herman Kabat, a man who received the bachelor of science degree from New York University in 1932. In 1936 he moved to the University of Minnesota where he served as instructor in physiology and also studies medicine. He received his medical doctorate in 1942. When Dr. Karbat meet Sister Kenny suggested that certain change. She does not receptive his ideas. So that he decided to pursure the treatment of patients. Upon the establishment of the Karbat- kaiser Institute to be opened in 1946. Margaret Knott, the first physical therapist to be employed by him and to become his head physical therapist. In 1948 Vallejo center was opened. Dr. Kabat developed the PNF method combined motions to ascertain the effectiveness of maximal resistance and stretch in facilitating the response of a weak distal muscle. He identified mass movement patterns that were spiral and diagonal in character in 1965. Margaret Knott presented lecture at tile APTA Annual Conference in Las Vegas. The title was In the groove. On December 18, 1978 she passed away at her home in Vallejo. Marie-Louise Mangold is director of the Kaiser Foundation Rehabilitation Center now. She is the Vice President of International Proprioceptive Neuromuscular facilitation Association. About 20 physical therapist working teaching and study at KFRC in Vallejo. PNF neuromuscular mechanism becomes integrated and efficient without awareness of individual muscle action, reflex and a multitude of other neurophysiological reactions. The principles of PNF are visual consideration, verbal consideration, and proprioceptive input consideration with tactile stimulation, joint receptors, appropriate facilitation, stretch reflex normal timing, irradiation, pattern of movement.

Deficiency and excess pattern differentiation is unique characteristic of traditional oriental medicine on diagnosis and treatment. This differentiation is accomplished through pulse, tongue diagnosis and question examination, but most of these processes need to be objectified for efficacious treatment and traditional medicine development. In this study, we developed the deficiency and excess pattern questionnaire for objectification of question examination. The deficiency and excess pattern questionnaire was made out through The Traditional Oriental Medical Literature with Delphi Technique. Patients who visited oriental medical hospital filled out the questionnaire by themselves. Diagnosis of deficiency and excess pattern are conducted separately by oriental medical doctors with more than 5 years' clinical experience. Various physical condition factors were derived for the deficiency and excess pattern questionnaire. (Ordinary health degree, pain pattern, fatigue, weight change, sweating, uncomfortable awareness on chest and abdomen) Deficiency symptoms group acquired internal consistency, but excess symptoms group did not. (Cronbach's ${\alpha}$ > 0.6) There were significant associations between doctor's diagnosis and deficiency and excess symptoms in 'ordinary heath degree', 'voice weakening', and 'chest distress' (p-value < 0.1) There were significant differences between deficiency and excess syndrome patients groups in deficiency questionnaire score but there were no significant differences between deficiency and excess syndrome patients groups in excess questionnaire score. We acquired the internal consistency and significant result of deficiency pattern questionnaire, but we can find out some difficulties in development of the excess pattern questionnaire. These difficulties are associated with insufficiency description of traditional literature and small number of patients diagnosed as excess pattern.

Ubiquitous is a Latin-derived word meaning "to exist at any time and place" like water or air. In computing, the word "ubiquitous" indicates an environment in which users have access to networks without any limitation regarding computer networks or places. Important issues in building Ubiquitous Korea (U-Korea) are the social problems appearing with a rapid increase in the old age population. Nowadays, with the rise of the nuclear family, the increase in the number of elderly people living alone, and the change in the status of women, both wives and husbands are employed outside the home, and the relatives who would be responsible for supporting the elderly sometimes are on long or short business trips, and it happens that old people can't be looked after. Therefore the government developed a wireless paging system for the sick, disabled, old and weak so that when an emergency happens, by just simply dialing 119, an emergency aid center could take prompt action. However, the present wireless paging systems composing the under-layer of the emergency aid information system have some problems, such as, a lack of reliability, problems among terminals, mobile transmitters and receiving terminals, the users' refusal to admit the need for the system and poor operational skills, administrators' perfunctory management and checks, etc. On account of these problems, the system efficiency has degraded and therefore a system upgrade is necessary. In this paper, we attempt to evaluate the newly implemented SAFE119 system, a new wireless paging system seeking to correct the problems of the current system.

Purpose: As there are more cases of forged brands, change of awareness is urgently required at the governmental, corporate and consumer levels. Therefore, this study aims to positively analyze the correlation between forged brand quality and purchase intentions perceived by consumers based on types of preference of luxury brands. Methods: In order to achieve the above purpose, this study derived a model of causal relationships among the forged brand quality, preference of typified luxury brands, and purchase intentions. SPSS 20.0 was applied for data processing. Frequency analysis ad descriptive statistical analysis were conducted for basic data and measurement tools were verified through feasibility and reliability analyses. Multiple regression analysis was conducted to verify the hypotheses. Results: Based on the results, only utilitarian quality positively (+) affected non-intrinsic preference while its impact on intrinsic preference was negative (-). On the other hand, hedonic quality was significantly positive (+) but the impact was not significant. Both utilitarian and hedonic qualities had significantly positive (+) impacts on the intentions to purchase forged brands with the impact of hedonic quality relatively higher. Conclusion: These results clarified that the overall consumption of Korean consumers had not entered its maturity, yet. Also, Korean consumers regard forged brands as alternatives to luxury brands mostly because of hedonic quality. As hedonic quality is added, Korean consumers' purchase intentions became higher. Based on these results, this study suggested the measures to be taken for the country to develop into an advanced country in the luxury market which is becoming more global and overcome the barrier of its old trend in imitation at the four levels of manufacturers, distributors, government, and consumers.

The ACL(Anterior cruciate ligament) is the smallest of the four main ligaments of the knee, but it is the primary stabilizer. Injuries have a tendency to occur when the foot is firmly planted and the knee is twisted. Any sports that requires acceleration, change of direction and deceleration can increase the chances of suffering an ACL tear. The incidence of severe knee sprains that involve the ACL are at an all-time high. Since 1980, the number of these injuries have increased at least three-fold. Although the rate of increase has been much less dramatic since the middle 1980s, even the ultra-modem releasable ski binding has not been able to start reducing the incidence of ACL injuries. An ACL injury prevention program developed for downhill skiers by the Vermont Safety Research group emphasized increasing awareness of situations that can potentially result in an ACL injury and pre-planning strategies if events, leading to these situations, begin to fall in place. As part of the above study by Ettlinger et al., an educational prevent program was developed to teach these principles and thus reduce the rate of serious knee injuries. Four thousand instructors and patrol at 20 ski resorts who received the training had a 62% decline in serious knee injuries compared to a similar group that did not receive this training. Whenever you fall, try not to fully straighten your legs. Don't try to get up until you've stopped sliding(unless you are try to avoid an obstacle or other skier). When you're down, stay down. And don't land on your hand. So, if you feel yourself falling: arms forward, ski plates together, hands over knee. Then you will be able to save your ACL.

An ad-hoc wireless network provides self-organizing data networking while they are routing of packets among themselves. Typically multi-hop and control packets overhead affects the change of route of transmission. There are numerous routing protocols have been developed for ad hoc wireless networks as the size of the network scale. Hence the scalable routing protocol would be needed for energy efficient various network routing environment conditions. The number of depth or layer of hierarchical clustering nodes are analyzed the different clustering structure with topology in this paper. To estimate the energy efficient number of cluster layer and energy dissipation are studied based on distributed homogeneous spatial Poisson process with context-awareness nodes condition. The simulation results show that CACHE-R could be conserved the energy of node under the setting the optimal layer given parameters.
