  • 본 연구에서는 대형할인점의 물리적 환경에 관한 기존연구를 통하여 산업별로 정리하였고, 할인점이 경비절감을 위해 직원배치를 최소화하고 물리적 시설로 소비자에게 소구해야하는 경영특성상 물리적 환경은 매우 중요한 것으로 점차 인식되고 있으나 기존의 연구에서 사용되어진 물리적 환경 변수들의 측정도구는 할인점 조사에 적용할 시 부적합한 부분이 많다. 따라서 본 연구에서는 대형할인점에 있어서 물리적 환경의 구성변수를 산업체의 전문가들과 심층토의를 거쳐 변수와 항목을 개발하였으며 그 과정을 구체적으로 설명하였다. 그 결과 도출된 측정변수는 쾌적성, 가시성, 접근용이성, POP로 분류되었다. 그리고 신뢰성과 타당성 분석결과를 거친 측정항목들에 대하여 대형할인점의 물리적 환경에 대한 요인구조와 측정모델의 타당성을 평가하기 위하여 LISREL 8.12를 이용하여 측정하였다. 본 연구의 결과를 살펴보면, 대형할인점에 있어서 물리적 환경의 구성요소인 쾌적성, 가시성, 접근용이성이 고객만족에 영향을 미치지만 POP는 매출증대에는 직접적인 관련성이 있으나 고객만족과는 서로 차원이 다르다고 판단할 수 있으며, 또한 고객만족과 구매의도, 구전의도 그리고 재 방문의도에 영향을 미치게 됨을 알 수 있다.

  • Objective : Depressive symptoms often coexist with other anxiety disorder symptoms. Furthermore, an anxiety disorder that is comorbid with a depressive disorder results in more severe symptoms and a poorer outcome prognosis. To understand the construct of depressive symptoms in anxiety disorder, this study investigated the factor structure of the Beck Depression Inventory among outpatients with anxiety disorders. Methods : All data were from psychiatric department outpatients at a university-affiliated hospital. We conducted a principal component analysis using data from 194 outpatients with DSM-IV anxiety disorders and calculated goodness-of-fit-indices. Results : Exploratory factor analysis revealed a four factor structure--Cognitive-affective symptoms (Factor 1), Somatic symptoms (Factor 2), Self-reproach (Factor 3), and Hypochondriasis/indecisiveness (Factor 4)--and a 57% total variance. This four-factor model demonstrated an acceptable level of model fit, and it fit better than did a three-factor solution from the literature on depressive disorder. Conclusion : This study's results suggest a difference in the construct of self-reported depressive symptoms in anxiety disorders. These findings also support a dimensional approach to studying anxiety and depression. Further studies may benefit from including comorbid depressive disorder and its influence on anxiety disorders.

  • Purpose: This study was conducted to assess the reliability and validity of the Korean version of the Coping and Adaptation Processing Scale-Short- Form in patients with cancer. Methods: The original scale was translated into Korean using Brislin's translation model. The Korean Short-Form and the Functional Assessment Cancer Therapy-General were administered to 164 Korean patients with cancer using convenience sampling method. The collected data were analyzed using SPSS 23.0 and AMOS 23.0. Construct validity, criterion validity, test-retest reliability, and internal consistency reliability of the Korean Coping and Adaptation Processing Scale-Short-Form were evaluated. Results: Exploratory factor analysis supported the construct validity with a four-factor solution that explained 60.6% of the total variance. Factor loadings of the 15 items on the four subscales ranged .52~.86. The four-subscale model was validated by confirmatory factor analysis (Normed ${\chi}^2=1.38$ (p=.013), GFI=.92, SRMR=.02, RMSEA=.05, TLI=.94, and CFI=.95), and criterion validity was demonstrated with the Functional Assessment Cancer Therapy-General. Cronbach's alpha for internal consistency of the total scale was .83 and ranged .68~.81 for all subscales, demonstrating sufficient test-retest reliability. Conclusion: The Korean version showed satisfactory construct and criterion validity, as well as internal consistency and test-retest reliability.

  • Purpose: The aim of this study was to test the validity and reliability of the Korean version of the Quality of Nursing Work Life (QNWL-K) scale. The scale measures the reported quality of the nurse' work life among Korean nurses. Methods: The QNWL-K was developed through forward-backward translation techniques. An internal consistency reliability and construct validity using exploratory analysis were conducted using SPSS/WIN (21.0). Survey data were collected from 309 nurses who worked in two tertiary hospitals, four general hospitals, and two hospitals in Seoul and Gyeonggi, South Korea. Results: Factor analysis results of the revised QWNL-K demonstrated that it has a four-factor structure (work context, support systems for home/work life, work design, and staffing) that supports construct validity. Factor loadings of the 36 items ranged from .30~.77. The QNWL-K showed reliable internal consistency from Cronbach's ${\alpha}$ for the total scale of .93. Conclusion: The findings support that the QNWL-K has satisfactory construct validity and is a reliable measure of nursing work life in Korea.

  • Purpose: The purpose of this study was to evaluate the validity and reliability of the Korean version of Person-Centered Practice Inventory-Staff (PCPI-S) for nurses. Methods: The English PCPI-S was translated into Korean with forward and backward translation. Data were collected from 338 nurses at one general hospital in Korea. Construct validity was evaluated with confirmatory factor analysis, convergent validity, and discriminant validity. Known-group validity was also evaluated. Cronbach's α was used to assess the reliability. Results: The PCPI-S Korean version consisted of 51 items in three areas: prerequisites, the care environment, and person-centered process. The comparative fit index (CFI) and values of person-centered care process were improved after engagement and having sympathetic presence items were combined as one component. The construct validity of PCPI-S Korean version was verified using four-factor structures (.05 < RMSEA < .10, AGFI > .70, CFI > .70, and AIC). The convergent validity and discriminant validity of the entire PCPI-S question were verified using a two-factor structures (AVE > .50, construct reliability > .70). There was an acceptable known-group validity with a significant correlation between the PCPI-S level and the degree of person-centered care awareness and education. Internal consistency was reliable with Cronbach's α .95. Conclusion: The Korean version of PCPI-S is valid and reliable. It can be used as a standardized Korean version of person-centered care measurement tool. Abbreviation: RMSEA = root mean square error of approximation; AGFI = adjusted goodness of fit index; AIC = Akaike information criterion; AVE = average variance extracted.

  • In this paper, we propose a fuzzy control method for improving the control performance by automatically tuning the scaling factor. The proposed method is that automatically tune the input scaling factor and the output scaling factor of fuzzy logic system through neural network. Used neural network is ADALINE (ADAptive Linear NEron) neural network with delayed input. ADALINE neural network has simple construct, superior learning capacity and small computation time. In order to verify the effectiveness of the proposed control method, we performed simulation. The results showed that the proposed control method improves considerably on the environment of the disturbance.

  • Purpose: The purpose of this study was to validate the Korean version of shortened Nursing Decision-Making Instrument developed by Lauri & $Salanter{\ddot{a}}$(2002). Methods: The subjects were 247 nurses working in eight hospitals of Korea. Data were collected by questionnaires from June to July, 2012 and were analyzed by Principal Component Analysis for construct validity and Cronbach's ${\alpha}$ coefficient for reliability. Results: Factor loadings of the four subscales ranged from .32 to .73. The explained variance from the four factors was 48.54% of the total variance. The factors were named 'implementation of plan, monitoring and evaluation', 'plans of action', 'data collection', and 'data processing and identification'. The first factor consisted of 6 items which explained 13.21% of the total variance and the second factor contained 8 items. The Cronbach's ${\alpha}$ coefficients of the four subscales were from .64 to .81. Conclusion: The Korean version of the shortened Nursing Decision-Making Instrument has satisfactory construct validity and reliability. However, that the scores of the analytic items weren't reversed unlike the analysis method of the original tools is the biggest limitation of this study. In addition, based on the fact that there were several discrepancies for item interpretation of Korean comparing to the findings of the instrument development study, repetitive researches would be suggested.
