This study explored the quality of nursing services in relation to a nurse's psychosocial factors (type A behavior pattern, self-esteem, locus of control, and anxiety), job stress, and fatigue. This study targeted 503 nurses who currently work at six different general hospitals in Daejeon city, The data was collected by self-administered questionnaire which was surveyed from April 1 to June 30, 2014. As the result of analysis of covariance, psychosocial factors affect the quality of nursing services more than job stress or fatigue. In addition to that, as parts of psychosocial factors, high self-esteem and low fatigue, job stress, and anxiety increase the quality of nursing services. The research above implies that the quality of nursing services of nurses who work at the general hospital has a correlation with not only the psychosocial factors but also job stress, and fatigue.

This study attempted to identify convergent influence on depression and its association with job seeking stress, academic burnout and anxiety among college students. Data collection was carried out using a self-administered questionnaire from Nov. 12, 2018 to Dec. 14, 2018 and the target was randomly selected 304 students from colleges located in J area. Depression was positively correlated with job seeking stress, academic burnout and anxiety. The covariance structure analysis showed that the job seeking stress, the higher academic burnout and the higher anxiety tend to increase depression. These results show that to lower college students' depression, it is necessary to try to lower job seeking stress, academic burnout, and anxiety. These results are expected to be utilized for employment counseling, academic counseling, and expansion of resources for psychological stability and various interventions that lower the depression of college students. In future studies, the survey about additional factors of influence on the depression of college students will be needed.

Although longitudinal studies mainly produce multivariate longitudinal data, most of existing statistical models analyze univariate longitudinal data and there is a limitation to explain complex correlations properly. Therefore, this paper describes various methods of modeling the covariance matrix to explain the complex correlations. Among them, modified Cholesky decomposition, modified Cholesky block decomposition, and hypersphere decomposition are reviewed. In this paper, we review these methods and analyze Korean children and youth panel (KCYP) data are analyzed using the Bayesian method. The KCYP data are multivariate longitudinal data that have response variables: School adaptation, academic achievement, and dependence on mobile phones. Assuming that the correlation structure and the innovation standard deviation structure are different, several models are compared. For the most suitable model, all explanatory variables are significant for school adaptation, and academic achievement and only household income appears as insignificant variables when cell phone dependence is a response variable.

본 연구에서는 2개의 사례지구에 대한 설문조사를 통해 서비스평가 구조모형을 개발하였다. 모형의 가설로서 요인분석과 신뢰성 분석 등을 통해 구성된 '질적서비스에 대한 인식', '이동성에 대한 인식 '환승에 대한 인식', '경제성에 대한 인식'이란 인지서비스(Perceived service)를 나타내는 4개의 잠재변수는 '개인속성'과 '교통특성'이란 잠재변수의 영향을 받으며, 상호 구조적인 관계를 가지고 전반적인 만족도로 대표되는 '서비스평가'에 영향을 미친다고 가정한다. 모형추정결과, 기초적합지수(GFI)가 상인·월성 0.864, 지산·범물 0.807로 나타났고, 조정 적합지수 (AGFI)는 상인·월성 0.823. 지산·범물 0.759로 나타나 적합성은 대체로 양호하다고 할 수 있다. 또한 두 지역 모두에 있어서 잠재변수 간이나 잠재변수와 관측변수간의 인과계수의 유의성도 2, 3개의 인과계수를 제외하면 모두 5% 유의수준에서 유의한 것으로 나타나 전체적으로 모형이 타당하다고 판단된다. 상인·월성의 경우, 운전기사에 대한 인식치가 '서비스평가'에 미치는 영향력이 가장 크며, 요금수준과 더불어 직접적으로 '서비스평가'에 영향을 미치고 있다 기타 편리성, 쾌적성, 시설 및 운영성이 중요한 원인으로 작용하고 있다는 것을 시사하고 있다. 지산·범물의 경우, 쾌적성, 시설 및 운영성, 편리성이 '서비스평가'에 직접적으로 큰 영향력을 미치고 있다. 특히 이러한 '질적서비스에 대한 인식'은 버스의 현행 요금수준과 대기시간에, 그리고 유의성이 높다고 할 수 없지만 이용자의 연령과 버스이용빈도에 영향을 받고 있는 것으로 나타났다.

This paper investigates how In-store crowding influences behavioral intention with mediating consumer emotion within store. We performed covariance structural analysis based on 486 subjects on family restaurants. The results showed that perceived In-store crowding negatively influences positive-customer emotion and positively influences negative-customer emotion. In addition, In-store crowding on intention to behavior channeled through consumer emotion. Finally, we discuss the results of analysis and suggest research limitation and future study.

Single PPM Quality Innovation Movement is originally developed quality program in Korea for supplier's quality level-up since 1995. The quality target is below the 10ppm(parts per million) in outgoing quality and delivered goods plus field claim. Recently 1,053 companies is received Single PPM Quality Certification from government. This quality program is to realized the anticipated results not only duality level's increasing, but also company's confidence, competitiveness. We were able to obtain participations of 75 questionnaire, and derived statistics by means of SPSS/PC version 10.0. In this study, we find the bottleneck factor for promotion and upgrade S-PPM, and suggest a way out of difficulties.

In the past decade, Pine & Gilmore set out the vision for a new economic era, the experience economy, in which consumers are in search for extraordinary and memorable experiences. The purpose of this study is to investigate the relationships among walking tourist's experiences, walking tourist satisfaction and revisit intention as the social interest on walking tour has risen. A total of 250 respondents completed a survey. Using structural equation modeling (SEM) technique, the results reveal the effects of Esthetics(indulged in environments) and Escapism(diverging to a new self) that impact on walking tourist satisfaction and on revisit intention indirectly. Overall, finding of this study enhance the theoretical progress on the experiential concept in walking tour and offer important implication for walking tour marketers.
