If an appliance perceives the location or health condition of a resident in the smart home, it can provide more intelligent service actively. That is, while the conventional appliance is operated by manual input of a resident, the location-based human adaptive appliance detects the resident's information such as location, activity pattern, or health condition by itself and provides the most suitable living condition for the resident autonomously. This paper presents the real-time location-based metabolic rate estimation method that measures the amount of physical activity (metabolic rate) for location-based human adaptive air-conditioner. And, the feasibility of the algorithm is evaluated experimentally on a test bed using the pyroelectric infrared sensor-based indoor location aware system (PILAS) that is a non-terminal-based location-aware system.

Pipe design normally requires pump power, discharge or pipe diameter for each condition given. Due to several investigators the pipe friction factor con now be estimated by explicit way for a wide range of flow condition. In various problems of pipe design, however, the flow condition cannot be pre-determined even for a uniformly rough pipe. In these cases a lot of iterations are often required to have an accurate solution with ordinary approach. This paper presents the direct computation method of discharge and pipe diameter without any iteration process. Introducing the power law of friction factor, various non-dimensional physical numbers are derived such as power-diameter number, power-discharge number, diameter-slope number and discharge-slope number. One of the physical numbers concerned with discharge or pipe diameter can be related to a combination of the other in an explicit way.

A numerical analysis has been conducted to investigate and characterize the unsteadiness of flow structure and oscillatory vacuum pressure inside of a supersonic diffuser equipped to simulate the high-altitude rocket test on the ground. A physical model of concern includes a rocket motor, a vacuum chamber, and a diffuser, which have axisymmetric configurations, using nitrogen gas as a driving fluid. Emphasis is placed on investigating physical phenomena of very complex and oscillatory flow evolutions in the diffuser operating at very close to the starting condition, i.e. minimum starting condition, which is one of major important parameters in diffuser design points of view.

PURPOSE: This study examined the actual condition of physical therapy in residential facilities for the disabled and determined the degree of job satisfaction of physical therapists. METHODS: In this study, data were collected using a structured questionnaire targeting 117 physical therapists (male: 49, female: 68) working in residential facilities for the disabled. The questionnaire consisted of 21 items, including six general characteristics, one job satisfaction, and 14 actual situation-related items. RESULTS: The job satisfaction of the physical therapists working in residential facilities for the disabled was 3.81 ± .83, which was between 'normal' and 'satisfactory'. One physical therapist worked in 91.5% of places. The physical therapy room was used only by the physical therapist, occupational therapist or speech therapist, and a nurse and other departments in 65.8%, 9.4%, and 23.1% of cases. On average, six to 10 patients per day were treated the most with 45.3%, followed by physical therapy alone at 19.7%, and work related to medical rehabilitation and other departments at 72.7%. A higher number of overtime hours and nurses resulted in lower job satisfaction. CONCLUSION: The job satisfaction of physical therapists working in residential facilities for the disabled was similar to those of physical therapists working in medical institutions, but the factors affecting the job satisfaction were different. Professionalism in physical therapy was not secured, and the relationships with colleagues were an important factor in increasing job satisfaction.

Background : With its research and analysis on the actual condition of the oriental medical treatment and the oriental physical therapy and With its research on the physical therapists' awareness of the oriental physical therapy, Providing the basic information for the physical therapy development and the national heath improvement in the future. Methods : This research had performed random sampling survey of 200 physical therapists in Busan city and had excluded 4 with insincere answers or some ommission of survey contents. Result : The first most frequent disease type of the oriental medical center inpatients is paralytic sequela, the second is lumbago, the next is apoplexy in order. The first most frequent disease type of the outpatients is lumbago, the second is stiffness in the shoulder, the next is the sprain in order. And, it came out that most of frequent disease are required the physical therapy. Conclusion : This research results show high demands as well as the necessity of the oriental physical therapy. It seems physical therapy association needs very serious examination on the oriental physical therapy execution.

Purpose : The purpose of this study for the physical therapy service was to investigate the satisfaction of the parent whose child has a disability and which factors affect their satisfactions. 153 questionnaires were surveyed from parents who experienced services of physical therapy offered in 3 general hospitals, 6 disabled daycare centers and 2 welfare centers located in Jeonnam area for one month, Sep. 2009. The results of this study were as follows: 1. In the parent's satisfaction of physical therapy program, there was a significant difference in satisfaction according to their place of residence(p<.05). 2. In the child's satisfaction of physical therapy program, there was a significant difference in satisfaction according to their diagnosis time(p<.05). 3. In the general characteristics of the condition of workroom, the satisfaction of physical environment, therapist's attitude, and physical therapy program revealed the significant differences(p<0.05). In the satisfaction according to institution, only physical environment has a significance(p<.05). 4. The satisfactions were $4.17{\pm}0.67$, $3.97{\pm}0.60$ and $3.90{\pm}0.68$ for physical therapist's attitude, physical environment and physical therapy program, respectively. The overall satisfaction revealed $4.01{\pm}0.58$, relatively high.

Most of physical therapists has thought be exposed themselves to risk of hospital infection but it is reported that have been low concern about infection management. Above like this haven t done systematical education on hospital infection, also physical therapist's information management of infection disease is found very low. It is lack of driving information about disease condition of the patients. Physical therapists has thought their working room may be polluted a lots of micro-organism(%). The control situation of infection waste articles, only 53% responded that the controller has managed very intensive so we can feel to need more intensive It's reported that air culture investigation of physical therapy room has never initiated. To wash the hand, before, after treatment of the patients of physical therapist, is very low frequency. And 73% have responded that the time to wash the hand stays 15-45 second. It is examined that 70% physical therapy room is equipped with washing system, a response of 58% disinfects physical therapy room 1-2times per one month. 36% responded disinfection of treatment modality have done everyday, 25% responded have never done. The location physical therapy room is above one floor - 65%. A response of 57% is ventilation system sufficiency, it is considered that physical therapists needs more efforts on management of hospital infection.

The purpose of this study was to investigate the trunk and lower extremity muscle activity induced by three different intensity conditions (intensity 1, 3, 5) of whole body vibration (WBV) during bridging exercise. Surface electromyography (EMG) was used to measure trunk and lower extremity muscles activity. Eleven healthy young subjects (6 males, 5 females) were recruited from university students. The collected EMG data were normalized using reference contraction (no vibration during bridging) and expressed as a percentage of reference voluntary contraction. To analyze the differences in EMG data, the repeated one-way analysis of variance was used. A Bonferroni's correction was used for multiple comparisons. The study showed that EMG activity of the rectus abdominis, external oblique, internal oblique, erector spinae and rectus femoris muscles was not significantly different among three intensity conditions of WBV during bridging exercise (p>.05). However, there were significantly increased EMG activity of the medial hamstring muscle (p=.001) and medial gastrocnemius muscle (p=.027) in the intensity 3 condition compared with the intensity 1 condition. This result can be interpreted that vibration was absorbed through the distal muscles, plantar flexor and knee flexor.
