  • Objective : This study aimed to assess the applicability of the Yonsei Lifestyle Profile (YLP), initially developed for adults, for adolescents and verify its reliability and validity. Methods : This study evaluated the reliability and validity of the YLP among 436 middle and high school students in South Korea. The internal consistency of this scale was analyzed using Cronbach's alpha and Spearman-Brown's coefficient. Concurrent validity was assessed using Pearson's correlation coefficient with the Korean Youth Physical Activity Questionnaire, the Korean version of the Children and Adolescents Participation Scale, and the Nutrition Quotient for Adolescents. Results : The overall internal consistency of the YLP items demonstrated high reliability, with a Cronbach's α of .811 and Spearman-Brown's coefficient of .779. Significant positive correlations were observed for physical activity (r=.555, p<.01), activity participation (r=.177, p<.01), and dietary habits (r=.633, p<.05), indicating consistent correlations with the related scales. Conclusion : This study analyzed the YLP targeting adolescents and confirmed its high reliability and significant validity in the areas of physical activity, activity participation, and dietary habits. These findings suggest that the YLP can be utilized as a reliable tool for evaluating healthy lifestyles among adolescents.

  • The purpose of this study was to test the validity and reliability of the Satisfaction with Simulation Experience (SSE) scale for evaluating high-fidelity simulation education for nursing students. Participants were 174 nursing students, seniors enrolled in two colleges in two different regions. Collected data were analyzed using SPSS / WIN 22.0 and tested for construct validity (factor analysis, group comparison test) and reliability (internal consistency). Factor analysis revealed 17 items and 3 factors explaining 71.581% of the variance. Group comparisons showed that satisfaction with simulation training differed significantly across satisfaction to a college life and school record. Internal consistency reliability for all items was .945. For each sub-domain, the reliability coefficient was .929 for 'Debrief', .908 for 'Clinical learning and reflection', and .860 for 'Clinical reasoning'. Nursing students' mean satisfaction with simulation using the high-fidelity simulator was 3.92. Results of this study are expected to be used for evaluating the satisfaction of nursing college students receiving high-fidelity simulation education, and to serve as groundwork for the development and application of nursing simulation education.

  • The aim of this study was to explore the reliability and validity of the Korean version of the Recovery Assessment Scale in psychiatric patients. The original RAS was translated into Korean and the content was verified through back-translation procedures. This study included 142 patients who had chronic mental illness and were aged 18 or older. The subjects were assessed by using RAS-K, the 12-item Dispositional Hope Scale(DHS), the 28-item Mental Health Recovery Measure(MHRM), the 32-item Behavior and Symptom Identification Scale (BASIS-32). In the reliability test, Crobach's a coefficient and test-retest reliabilities were 0.92 and 0.79, respectively, indicating that the RAS-K has good internal consistency. In the analysis of the concurrent validity of the RAS-K, there were significant correlations between the RAS-K and DHS(r=.675, p<0.01), and between the RAS-K and MHRM(r=.816, p<0.01), but lower correlations with symptoms and clinician-related measures of psychiatric functioning. Factor analysis resulted in a five factor solution accounting for 62.476% of the common variance. Our study indicates that the RAS-K is an appropriate instrument to assess recovery in Korean psychiatric patients.

  • This study was performed on 171 workers in the Kyungbuk Kumi industrial complex to verify the validity and the reliability of the Korean version of the constitutions in a Chinese medicine questionnaire. Each subjective fulfilled a questionnaire of 61 questions in 9 categories based on a self-assessment. All categories and each constitution's internal consistency were analyzed using the Cronbach's alpha coefficient to review the questionnaire's reliability, and factor analysis and correlation analysis were performed to review the validity. The reliability was satisfied with Cronbach's alpha coefficient for all categories and each constitution's internal consistency ranged from 0.601 to 0.925, and the validity was verified by factor analysis, which showed the same two factors of each constitution. Correlation analysis of each constitution showed statistical significance and strong positive correlations among 8 constitutions except for the gentleness type (P=0.0127). As a result, it is believed that the Korean version of the constitutions in Chinese medicine questionnaire can be useful for diagnosing the constitutions of Koreans.

  • We tested the capability of the pleasure and arousal dimension-based facial expression synthesis system and proposed the most effective interface for it. First, we tried to confirm the adequateness of the dimensional model as a basic structure of the internal states for the system. Fer it, subjects compared the 17 facial expressions on the two axes. The results validated the fundamental hypothesis of the system. Second, we chose 21 representative expressions from the system to test its performance and had subjects rate their similarities. We analyzed these data using multidimensional scaling methods and these results verified the system's reliability. Third, we compared the efficiencies of two interfaces -coordinate values and slide bars- to find the most suitable interface for the system. Subjects synthesise 25 facial expressions with each interface of it. The results showed that the visualization of two dimensional values into Cartesian coordinate is more stable as an input display of facial expression synthesis system based on dimensions.

  • 기후 내적 변동성(Climate Internal Variability, CIV)은 기후를 이해하는 데 중요한 역할을 하며 기후예측에 있어 주요 불확실성 원인들 중 하나이다. 본 연구는 다양한 이산화탄소 배출 시나리오에 대해 CIV와 기후학적 평균(Climatological Mean, CM)을 추정하는 것을 목표로 한다. 확률론적 날씨생성기(Stochastic Weather Generator)를 이용하여 국내 40개 기상 관측소에 대해, 30년에 해당하는 시단위 시계열 100개 앙상블을 생성하였다. CIV는 Detrend 방법과 Differenced 방법을 이용하여 추정되었으며, noise 계산값과 비교하였다. 그 결과, CIV 값과 noise 값들 사이의 correlation이 매우 높았으며, 제시된 방법론이 신뢰할 수 있음을 검증하였다. 국내 40개 지역에 적용하여 계산된 CIV와 CM의 주요 결과는 다음과 같다. (1) 국내의 대부분의 지역에 있어 평균적으로 CM과 CIV는 미래에 증가할 것이며, 그 증가 정도는 RCP 8.5의 경우와 먼 미래END(2071-2100년) 기간에서 더 커질 것이다; (2) CM과 CIV의 미래 변화의 특성은 강수의 특성 지수에 따라 다르다. 강수량의 양을 나타내는 3개의 지수(총 강수량, totPr, 일 최대 강수량, maxDa 및 시간당 최대 강수량, maxHr)와 강수량의 발생일수를 나타내는 지수(무강우 일수, nonPr)의 특성은 크게 다르다. (3) CIV와 CM의 변화 요인들 사이의 관계를 조사하면 maxDa와 maxHr에 대해서는 그들 사이에 높은 상관관계가 있지만 다른 지수에는 그렇지 않다. (4) 국내에서 CIV 값이 공간적으로 변동성이 큰 경우는 계절적으로 여름이며, 이는 totPr 및 maxDa에서만 유효하다. 시단위 시계열 앙상블을 생성하여 추정된 기후내적변동성 정보는 기후 변화의 영향을 평가하고 적절한 적응 및 대응 전략을 개발하는 데 도움이 될 것이다.

  • Objectives : This study developed and validated the Perceived Stigma of Delirium Scale(PSDS), which is designed to measure perceived stigma associated with delirium in patients suffering from that disorder. Methods : Based on a literature review of scales assessing stigma, a preliminary scale comprising seven items was developed. After recovering from delirium, 128 patients completed the PSDS and the Distress Thermometer (DT). Factor analysis was used to examine construct validity, and internal consistency and test-retest reliability were examined to ensure reliability. Concurrent validity was assessed using the correlation between the total scores on the PSDS and the DT. Results : Factor analysis yielded a single-factor structure from the seven candidate items. One item was excluded due to low factor loading. The internal consistency was computed and Cronbach's ${\alpha}$ was 0.85 for the total score. The overall test-retest reliability was 0.71, with items ranging from 0.58 to 0.83. The total score on the PSDS was significantly correlated with the DT score. Conclusions : The PSDS may be a reliable, valid instrument for evaluating perceived stigma in patients who have recovered from delirium. Further study of the perceived stigma by delirium patients is required to assess the implications of the PSDS for clinical practice and research.
