  • A key comparison has been made between the air-kerma standards of the National Institute of Metrology (NIM), China, and other Asia Pacific Metrology Programme (APMP) members in the medium-energy X-ray. This paper reviews the primary standard Free-air ionization chamber correction factor experimental method and Monte Carlo simulation method in the NIM. The experimental method and the Monte Carlo simulation method are adopted to obtain the correction factor for the medium-energy X-ray primary standard free-air ionization chamber at 100 kV, 135 kV, 180 kV, 250 kV four CCRI reference qualities. The correction factor has already been submitted to the APMP as key comparison data and the results are in good agreement with those obtained in previous studies. This study shows that the experimental method and the EGSnrc simulation method are usually used in the measurement of the correction factor. In particular, the application of the simulation methods is more common.

  • Occupational Stress is defined the stress which occurs in the workplace or organization. In Korean workers, the rate of occupational stress was 87.8% which was the highest level among OECD countries(average 80.0%). The purpose of this study was to examine the empirical verification of the Korean Occupational Stress Scale(KOSS) in physical therapists. For this purpose, the subject of this study was set up physical therapists who were working at Gyeonggi province and collected from 388 persons by using purposive sampling. The collected data was conducted explanatory factor analysis and confirmatory factor analysis in order to ascertain factor structure and practical verification of KOSS. Major results were as following: first, the reliability of KOSS was 0.83, and it means that a measure of internal consistency is high. Second, the KOSS result of physical therapists was composed 7 subscales(job demand, insufficient job control, job insecurity, interpersonal conflict, occupational system and lack of reward, organizational climate) and that is more appropriate measurement scale than the original one by using explanatory/confirmatory factor analysis. This study could be contributed as a tool for evaluation and outcome of the basic information of related occupational stress in physical therapists.

  • The purpose of this study was to examine the validity and reliability of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC)-VA3.0 in patients with hip and knee osteoarthritis (OA). The sample consisted of 301 patients who had received treatments at the physical therapy units of 5 medical institutions in Andong City in june 2006. Questionnaires on the WOMAC were recruited by 12 physical therapists. The internal structure and reliability of the scales were evaluated by means of item-internal consistency (Cronbach's alpha coefficient: ${\alpha}$), item-discriminant validity, and Pearson's relation coefficient. To explore construct validity, we conducted a principal component factor analysis with varimax rotation analysis. The criterion for factor extraction was an eigenvalue >1.0. The average age of the patients was 62.1 years. All WOMAC subscales (pain, stiffness, and physical function) were internally consistent with Cronbach's coefficients of .81, .91, and .80, respectively. The internal consistency reliability of item-each scale were also internally consistent with Cronbach's coefficient of .89 (Pearson's correlation coefficient: .71~.84), .93 (.89~.91), and .96 (.67~.91), respectively. However, high correlation was found among 3 items (.66~.83, .66~.67, and .67~.83), so the item-discriminant validity was low (${\alpha}$ coefficient: .81, .91, .80, respectively). The construct validity by factor analysis was low because it was not consistent With WOMAC-VA3.0. In conclusion, the results reported here confirm the reliability of the WOMAC in patients with OA of the hip and knee. The collection of information on the hip and knee osteoarthritis using this instrument was acceptable to patients. A further prospective multi-center study will be necessary to prove the construct validity.

  • The purpose of this study was to identify the physical surroundings and the salesperson's service in apparel stores, and to examine their effects on customer satisfaction and the intention to repurchase. The data was collected from a questionnaire conducted on 312 female adults who had just finished shopping, and was analyzed by frequency analysis, factor analysis, reliability analysis, regressive analysis and ANOVA analysis with SPSS 10.0. The results were as follows: (1) As a result of the factor analysis, five factors were identified with regard to physical surroundings: spatial layout and functionality, presentation and aesthetics, ambience, convenience, and information. The factors pertaining to the salesperson's service in apparel stores were divided into four dimensions: knowledge and assurance, convenience and responsiveness, etiquette, and empathy. (2) As far as physical surroundings are concerned, spatial layout and functionality, presentation and aesthetics, ambience, and convenience were all found to influence customer satisfaction. In terms of salesperson's service, convenience and responsiveness, etiquette, and empathy each had an influence on customer satisfaction. (3) Furthermore, physical surroundings and the salesperson's service influenced the intention to repurchase. The intention to repurchase is influenced by spatial layout and functionality, ambience, convenience, and information with regard to physical surroundings, by knowledge and assurance, convenience and responsiveness, and empathy with regard to the salesperson's service. (4) It was revealed that the significance of the physical surroundings and salesperson service factors varies depending on the consumer's age, level of education, and income.

  • Purpose: The purpose of this article is to identify whether the physical therapists perceive the important factors influencing the motor development in children with cerebral palsy differently. Methods: Study participants included 58 pediatric physical therapists. They were recruited from the internet communities for physical therapists. The data was collected through a web-based questionnaire using Google Documents tool. Questionnaire was focused on the importance (10-point scale) of each factor influencing the motor development in children with cerebral palsy. The mean scale of each factor was compared by itself and according to the participants' career characteristics. Results: The personality characteristics received the least importance rating (6.77) in comparison with other domains (healthcare service: 7.70, family ecology: 7.53, secondary impairment: 7.53, primary impairment: 7.45). In the detailed items, home exercise (8.33) received the highest mean importance rating, while sociability (6.03) received the lowest mean importance rating. Comparing the importance of factors by the type of work institution, subjects working in the welfare institutions perceived the contextual factors (personality characteristics, family ecology, healthcare service) as more important than those working in the medical institutions. Conclusion: The authorsuggests that pediatric physical therapists should try to have an identical approach by reaching a consensus. Also, the support for family-centered service to children with cerebral palsy should be strengthened.

  • Purpose: The aim of this study was to examine the validity and reliability on Psychometric Arthritis Impact Measurement Scale-Short Form (AIMS-SF) in patients with knee osteoarthritis(OA). Methods: The sample consisted of 62 patients who had received physical therapy at the physical therapy units of the Andong Medical Center, Sungso Hospital, Ahn Orthopedic Surgery Clinic, and St. Luke Clinic in Andong city in June 2006. Questionnaire on the AIMS-SF was recruited by 5 physical therapists. The internal structure and reliability of the scales were evaluated by means of item-internal consistency(Cronbach's alpha coefficient: ${\alpha}$), item-discriminant validity, Pearson's relation coefficient. To explore construct validity we conducted a principal component factor analysis with varimax rotation analysis. The criterion for factor extraction was an eigenvalue >1.0. Results: 62 OA patients's an average $age{\pm}standard$ deviation was $53.8{\pm}14.4$ years (range: $40{\sim}81$ yr). The internal consistency reliability of 11 items, as estimated by Cronbach's ${\alpha}$ coefficient, was high ranging $0.60{\sim}0.78$ (except for 0.40 for mobility level and -0.48 for mood). The internal consistency reliability of item-each scale was also high $0.82{\sim}0.93$ (except for 0.48 for mood). Of 11 items, the item-discriminant validity on 6 items was high (${\alpha}$ coefficient range: $0.11{\sim}0.25$), however, others (0.57 for tension level, 0.48 for arthritis pain, 0.41 for walking and bending, and 0.40 for work) were a little low. The construct validity by factor analysis was a little low. Conclusion: In conclusion, the results reported here confirm the validity and reliability of the AIMS-SF in patients with OA of the knee. The Collection of information on health status using this instrument was acceptable to patients. A further prospective multi-center study will be necessary to prove the construct validity.
