Purpose: This study was conducted to develop an instrument to measure coping in emergency situations. Methods: The process included construction of a conceptual framework, generation 60 primary items, verification of construct validity and extraction of final items. The.60 preliminary items were reviewed for content validity by seven experts and were tested to evaluate inter-item correlation coefficient by three groups of elementary school students. From November 1 to December 10, 2008, data were collected from 920 elementary school students according to residential characters (major city, small town, rural area). Item analysis, factor analysis with rotation Varimax and Cronbach's alpha were used to analyze the data. Results: 1) There were 45 items in the final instrument categorized into 8 factors. 2) The factors were labeled as "Call for help and check" (8 items), "Care for common symptoms" (6 items), "Appropriate response for the situation" (5 items), "Evacuation" (6 items), "Care for tissue damage" (8 items), "Care for injury by heat, cold or foreign body" (6 items), "Offer help" (4 items) and "Rescue & escape" (2 items). 3) Cumulative percent of variance was 53.10% and eigen values ranged from 1.04 to 13.38. 4) Cronbach's alpha for the total was .943 and ranged from .527 to .869. Conclusion: Validity and reliability of the scale are confirmed in this study showing its utility for measuring coping in emergency situations with elementary school students. Utilization of the scale will also contribute to designing appropriate coping education programs for elementary school students.

Purpose: This study intended to analyze the validity of clinical effectiveness data of clinical trials testing systemic titrated extract of Zea Mays L. unsaponifiable fraction chemotherapeutic agent. Material and Methods: Among 5 clinical trials claimed as proof of clinical effectiveness on the Web site of the manufacturer of this chemotherapeutic agent, a review of 4 clinical trials, written in either Korean or English, was conducted. Data were extracted from studies for the following variables: year of publication, age, sample size, follow-up period, combination with contemporary periodontal treatments, randomization, randomization check, blinded measurement, and statistical test type. Results: The study subjects' age intervals were too diverse to decide a common target population to generalize the findings. No study stated clearly the rationale for the sample size determination. Follow-up period to observe the start of clinical effectiveness was inconsistent and decided without any rationale of pathophysiological latent period. Randomization to make the comparisons on the same start line was performed but failed in a study. Randomization effect was not checked in 4 studies. Performance of blinded measurement of clinical outcomes to prevent bias was unclear in 2 studies. Type of statistical test was inappropriate in 3 studies. Conclusions: Based on the analysis of the validity of data on clinical and demographic variables, the four available clinical trials have not demonstrated compelling evidence of therapeutic effectiveness of systemic titrated extract of Zea Mays L. unsaponifiable fraction chemotherapeutic agent to improve prognosis of periodontal disease either with the contemporary periodontal treatment or without it.

1. Objectives This is a statistical study on the Reliability and Validity of the Revised Questionnaire for the Sasang Constitution classification(QSCC II +). 2. Methods To analyze the reliability; we gathered the results of the QSCC II + of 266 people. Each person took the questionnaire three times, and the interval of the examinations were about one year. With the results, we used stratified analysis to check up the consistency rate of three examinations, and analyzed the tendency of agreement by crosstabs to get the kappa value. For the validity, we gathered the results of the QSCC II + of 587 people who were Taeumin, Soyangin, Soeumin. They took the questionnaire once, and SCM specialists strictly examined to diagnose their Sasang constitutions. We compare their results of the QSCC II + to the diagnostic result of their Sasang constitutions, and analyzed by crosstabs to get the rate of accuracy of the QSCC II +, and the kappa value for the measure of agreements. 3. Results and Conclusions The expected rate to get the same results was 54.5% in Soyangin, 68.1% in Taeumin, 65.7% in Soeumin, and kappa value was $0.311{\sim}0.414$, which means the reliability of the QSCC II + is analytically significant. The accuracy of the results of QSCC II +, compared to the diagnosis of the SCM specialists, was 58.4%, but increased up to 60.8%, and validity also became moderately good(K=0.412) by age limitation. Because in the 70's results of the QSCC II + isn't likely to agree to the diagnosis of the SCM specialists.

본 연구는 메타분석을 기반으로 한 편익이전 방법과 자료 수집을 위하여 지리정보시스템(GIS: geographic information system)을 활용하여 쓰레기 매립지 선택을 위한 7개 후보지들의 사회적 비용을 추정하였다. 그리고 MA-1, MA-2, 직접편익전달 방법을 타당성(validity), 신뢰성(reliability) 관점에서 검토해 보았다. 타당성(validity)은 메타분석을 기반으로 한 편익이전에 의한 추정치와 원래의 값의 차이의 여부를 통계적으로 검정하는 것이고 신뢰성(reliability)은 추정치와 원래의 값의 % 차이의 절대값을 이용해서 유사성을 검토하는 것이다. 연구 결과는 쓰레기 매립지 선택을 위한 후보지들의 사회적 비용이 직접 비용에 비해서 상당히 크고 주변지역의 경제적 특성에 의해 큰 영향을 받을 수 있음을 보여준다. 그리고 타당성과 신뢰성의 기준으로 메타모형들은 직접적 편익이전에 비해서 선호된다는 것을 보여준다. 메타분석을 기본으로 한 편익이전 방법은 시간, 비용, 혹은 자료부족 때문에 직접적인 방법을 활용하기 어려운 경우 하나의 대안이 될 수 있다. GIS는 각 후보지의 특정 지역 내 자료를 수집하는 데 도움을 줄 수 있다.

Objective : GRIT is a non-cognitive trait which is defined as perseverance and passion for long-term goals. It predicts success, performance and thedifference from other traits. The purpose of this study was to examine the reliability and validity of the Korean version of the GRIT scale. Methods : A total of 92 patients were enrolled in the study. All patients received psychiatric assessment including Clinical Useful Depression Outcome Scale (CUDOS), Clinical Useful Anxiety Outcome Scale (CUXOS), Patient Health Questionnaire (PHQ-15), Connor-Davidson Resilience Scale (CDRS), Brief Resilience Scale (BRS), and GRIT as well as demographic assessment. Cronbach's alpha coefficient of total GRIT score and the split-half reliability of each item was calculated to assess test reliability. Exploratory and confirmatory factor analyses were performed to select the best fitting model and assess construct validity. Finally, a correlation analysis was performed to check convergent and discriminant validity. Results : Cronbach's alpha coefficient for GRIT was found to be 0.85 and all Cronbach's alpha were more than 0.8 even in cases where all items were deleted. We found 3 appropriate factor models in exploratory factor analysis, compared them with 3 models and chose the 2-factor model as the most suitable based on the best fit test. Finally, correlation of the GRIT with CUDOS, CUXOS, PHQ-15, CDRS and BRS were statistically significant (all p<0.01), with relatively low correlation coefficient. Conclusion : This study indicates that the Korean version of GRIT is a reliable and valid instrument for investigating individual power of passion and perseverance.

A network of MAC type was constructed in the Gyeonggi-do area to analyze the usefulness and validity of the Network RTK-GPS. Six sites were selected to conduct GPS observation for 24 hours, and by determining the ITRF of each site, coordinates were determined in connection with IGS network. Then check points which were established in Gimpo area were observed at least 7 times by Network RTK at 20 secs of retrieval intervals. The result showed high accuracy in the difference between the coordinates determined immediately by the in-field network survey and the current performance was 1-2cm. Its biggest benefit is the expanded range of survey and efficiency of practice. In summary, it is proved that a network survey has the accuracy, scalability and efficiency and it is expected that the network survey will contribute to the cadastral survey.

In this paper, the vibration characteristics of the trapezoidally corrugated plate are investigated by the analytical method. The corrugated plate is widely used as the structural elements because of its high stiffness and light weight. Because the corrugated plate is flexible in the corrugation direction and stiff in the transverse direction, it is treated as an equivalent orthotropic plate to analyze the corrugated plate simply. This equivalent plate must include both extensional and flexural effect to obtain the precise solution. The effective extensional and flexural stiffness of the equivalent plate are derived to consider these effects in the analysis. To demonstrate the validity of the proposed approach, the comparison is made with the previously published results and ANSYS solutions. Some numerical results are presented to check the effect of the geometric properties.
