Many researchers have proved that risk measurement of information systems is a very effective tool for improving confidence of information systems. However, information system risk in Korea still includes many subjective judgements. This study deals with applying a quantitative model to improve risk measurement of information system quality. First of all, we have come up with solutions to improve the evaluation efficiency on risk measurement. We have merged the risk guidelines of COBIT and CMM, and developed a quantified evaluation scheme that call by risk point. We have proved the validity of this model by interviews with experts and by case studies.

The purpose of this study was to assess the intra-tester and inter-tester reliability and validity of elbow flexion range of motion using a smart phone used by the general public. Thirty-one general people participated in this study. The range of motion in active elbow flexion was measured with a goniometer and smart phone over two times by two observers. The intra-taster and inter-tester reliability were evaluated using the intraclass correlation coefficient(ICC). The validity was measured by Pearson's correlation coefficient. The intra-observer reliability was good in all measured items ICC>0.900. The inter-observer reliability was high with ICC>0.806. All correlation coefficients of android app and goniometer were greater than 0.868 and showed a significant positive correlation (p<0.01). The range of motion measurement with a smart phone showed acceptable reliability. Therefore, using a smartphone to measure the range of motion of the elbow joint could provide convenience and economic benefits.

PURPOSE: To summarize the evaluation tools of balance [Berg Balance Scale (BBS), timed up and Go (TUG), forward reaching test (FRT)], gait [6 m walking Test (6MWT)], and strength [Chair Stand Test (CST)] for patients with dementia. METHODS: The following databases were searched: Pub MED, Cochrane, Sciences Direct, and Web of Sciences. The inclusion criteria were as follows: 1) repeated measurement design, 2) subjects with dementia, 3) use of testing tools such as the BBS, TUG, FRT, 6MWT, and CST, 4) report the reliability. One reviewer performed the quality assessment of diagnostic accuracy study and two evaluators performed data extraction independently. RESULTS: Six articles and one letter were included. The interrater reliability of 6MWT, TUG, and CST, were acceptable (ICC>.90). However, FRT had unacceptable reliability. In test-retest reliability, only BBS has acceptable reliability (ICC>.90). Others had various reliabilities. The risk of interrater reliability bias was low in all studies. However, the risk of bias of intrarater reliability was low in five studies and moderate in two studies. CONCLUSION: The interrater reliability of the 6MWT, TUG, and CST were acceptable. However, in test-retest reliability, only BBS has acceptable reliability. Therefore, we suggest the use of BBS to test the balance of dementia patients. In addition, the study of tool reliability according to the subtype of dementia is needed in the future.

Through the test of ESD(Electro Static Discharge) for PCB circuit, we are able to research on the ESD effect. This paper also studys on the ESD test method for measurement. In the measurement of the discharge current, we used current probe(TC-1). The applied voltage to the PCB metal is -3 kV HBM mode. In conclusion ESD influences exponentially greater impact in nearer PCB circuit.

The conditions for measurement of the interior noise should meet the international standards. However, due to the limitations in test conditions the possible errors in measurement equipment, reliability of the measurement results has been questioned. Hence, the test procedure for the interior noise measurement of KTX vehicles are reviewed and investigated with the reference of international standards. Furthermore, the acceptable tolerance is inspected through the analysis of the factors that influence the interior noise of the KTX vehicle.

This study intended to enhance understanding of concept and measurement of service quality and analyzed studies investigating dimension and attributes of service quality in both Korea and international foodservice industries. This study summarized many methodological issues related to service quality measurement, especially SERVQUAL. SERVQUAL has been criticized because performance-expectation difference operationalization threatened reliability and discriminant validity including shared method variance. Researcher suggests that future studies should understand clearly the concept of service quality and methodological issues of SERVQUAL prior to adapting SERVQUAL itself.

Objectives : To introduce and compare various headache measurement tools, in order to provide fundamental information for future clinical trials and development of oriental medicine measurement tools. Methods : Eight headache assessment scales, Migraine-Specific Quality of Life Questionnaire(MQoLQ), Migraine-Specific Quality of Life(MSQOL), Migraine-Specific Quality of Life Questionnaire(MSQ), The Headache Impact Questionnaire(HImQ), Headcahe Needs Assessment Survey(HANA), Henry Ford Headache disability Inventory(HDI), Migraine Disablity Assessment Scale(MIDAS) and Headache Impact Test(HIT-6), were searched through Pubmed. General character, the process of development, verification of reliability, internal consistency, responsiveness to patient's change and validity were reviewed. Results : In assessing the quality of life of migraine patients, MQoLQ can be used to measure the change within 24 hours, MSQ and MSQOL can be used to measure the change during a relatively longer period of time. The frequency and bothersomeness of headache can be easily measured by HANA. HImQ can be used to measure the intensity of headache and the influence on normal daily activities. HDI can measure the emotional difficulties of headache patients. HIT-6 and MIDAS makes measurements possible in a short period of time, and the reliability and validity have been verified numerously. HIT-6 and MIDAS are the most frequently used measurement tools because they are simple and easy for both the assessor and the patient to understand and use. Conclusions : In this study, various headache assessment tools have been reviewed. The assessed tools were widely used after being verified for their reliability and validity. We hope this study provides fundamental information in establishing future clinical trial and clinical practice guidelines. We also hope this study to contribute to the development of an oriental medicine assessment tool for headache.

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.
