  • 본 연구는 의료서비스기업에 종사하는 종업원의 성격 5요인 모델에 따라 종업원의 직무 만족(job satisfaction) 과 고객지향적 태도(customer orientation) 에 미치는 영향을 연구 하고자 하였다. 연구를 위해서 서울과 대구에 소재한 대학병원과 경기도에 소재한 중 소형 병윈의 간호사들을 대상으로 자기기입식 설문조사를 실시하여 총 207개의 유효 표본을 획득하였다. 통계분석로는 응답자특성을 파악하기 위해 빈도분석을 설시하였고, 측정모형의 신뢰성과 타당성 분석을 위해 신뢰성도 분석, 요인분석 및 확인적 요인분석을 실시하였다. 또한 의료서비스종업원의 성격 5요인 모델이 종업원의 직무만족과 고객지향적 태도에 통계적으로 유의한 영향을 미치는 요인을 실증적으로 검증하기 위해 구조방정식 모델 분석을 통해 실시하였다. 그 결과, 성격 5요인 모델은 종업원의 직무만족과 고객지향적 태도에 통계적으로 매우 유의한 영향을 미치는 것으로 나타났다. 이와 같은 결과는 국내에서는 의료서비스업종을 대상으로 성격 5요인 모델을 적용한 연구가 미비한 현재 시점에서 의미 있는 결과라고 할 수 있다. 직무만족, 역시 고객지향적 태도에 통계적으로 유의한 방향으로 영향을 마치는 것으로 나타나, 직무만족이 높을수록 고객지향적 태도가 높아질 수 있다는 것을 실증적으로 확인할 수 있었다. 이와 같은 연구 결과는 다음과 같은 시사점을 찾을 수 있었다. 첫째, 고객과 종업원의 상호작용을 통해 서비스가 전달되는 상황에서 고객 욕구를 인지하고 충족시키며, 요구된 서비스를 전달하고, 고객과 개인적인 관계를 평가할 수 있는 고객지향적 태도 측정모델의 이론적인 토대를 제공한 점이다. 둘째, 최근의 성격이론가들은 성격 5요인 모델이 개인의 성격특성에 있어서 개인차를 설명해주는 포괄적이고 공통적인 구조로 존재한다는 학문적 통합에 동의한다. 마지막으로, 본 연구를 통해서 의료서비스 종업원의 직무만족도는 고객지향적 태도에 통계적으로 매우 유의한 영향을 마치는지를 실증적으로 밝혔다는 것이다. 따라서 관리자들은 종업원의 직무만족도를 주기적으로 측정하여 불만족 요인을 찾아 해결하고, 높은 수준의 고객지향적 태도를 유지하기 위한 노력이 필요함을 시사해준다 하겠다.

  • This study aimed to validate the Awareness of Age-Related Change (AARC) scale developed by Brothers et al. (2019) for the Korean elderly. This study took the elderly people in Seoul (over 65 years old) as participants to examine the aging perception of the elderly themselves. For this purpose, we conducted exploratory and confirmatory factor analyses (EFA, CFA) with two samples (sample 1: N = 185; sample 2: N = 215). EFA revealed and CFA confirmed a two-factor structure consisting of awareness of gains and awareness of losses. Specifically, the awareness of losses had two subfactors consisting of awareness of losses in health and awareness of losses in non-health, while the awareness of gains had no subfactor. Finally, we examined the relationship between AARC, attitudes toward own aging, and emotions then discussed the implication, limitations of this study, and future direction.

  • This study has investigated the factors that make a science teacher effective by analyzing students' perception of teacher knowledge required in enhancing their science learning. The basic components of teacher knowledge identified by previous researchers have been confirmed through Exploratory Factor Analysis (EFA). Based on the findings of the EFA, the questionnaire has been further analyzed using Confirmatory Factor Analysis (CFA) by means of Structural Equation Modeling (SEM). In addition, the differences in students' perception on the identified factors of effectiveness have also been analyzed in terms of gender and achievement level. The findings of the EFA showed that five factors of science teacher effectiveness were identified; namely, substantive knowledge, syntactic knowledge, knowledge of students' understandings, knowledge of instructional strategies, and knowledge of assessment. These five components have been divided into two categories of teacher knowledge, SMK and PCK. What we found from the CFA was the respective high correlation between substantive and syntactic knowledge, knowledge of students' understanding and instructional strategies and the low correlation between substantive knowledge and knowledge of instructional strategies. Students perceived substantive knowledge as the most effective factor, knowledge of assessment as the least effective factor. Also, there have been considerable differences in students' perception by gender and achievement level. We proposed, based on the findings, that SMK and PCK need to be integrated into a coherent manner for the effective science teaching practice. This study provides some implications for science teacher professional development and the improvement of science teacher preparation program.

  • Internet addiction, one of adverse effects of the informatization, has become a very serious social problem. The purpose of this study is to seek solutions for the adverse effects of the informatization by analyzing the causal factors of internet addiction to maximize prevention of the internet addiction for college students. The three causal factors of the internet addiction: personal factors, familial factors, and social environmental factors are defined as the second confirmatory factors, and the first confirmatory factors for the each second confirmatory factor are reviewed for influential factors of internet addiction. The study concluded that the personal factors are the most influential factors of internet addiction for college students; furthermore, self-control and self-efficacy are key variables of the personal factors. Therefore, it can be effective ways to prevent internet addiction if countermeasures on self-control and self-efficacy of the personal factors are presented.

  • The purpose of this study was to verify the validity of Ohio State Teacher Efficacy Scale(OSTES: Tschannen-Moran, 2000) when used with Korean home economics teachers. To achieve this purposes, the surveys with 263 secondary school home economics teachers was conducted by the prime investigator. Statistical procedures included descriptive statistics, factor analysis, internal consistency. Cronbach's a was calculated to test the reliability of items and their internal consistency and Exploratory Factor Analysis(EFA) was conducted to test the structure of each factors with principal analysis and varimax rotation. Confirmatory Factor Analysis(CFA) was conducted to test the factor validity of this scale with AMOS program. The reliability test result of 20 items appeared Cronbach's a=.86. The factor analysis on teacher efficacy with 263 survey of secondary school home economics teachers produced 5 factors including efficacy in classroom management. efficacy in needs assistance, efficacy in instructional strategies, efficacy in environmental assistance and efficacy in teaming assistance. The validity of teacher efficacy scale was moderately verified by the confirmatory factor analyses(GFI=.87, AGFI=.84. CFI=.86. PNFI=.72, RMR=.05. RMSEA=.07). The results lend a support to the teacher efficacy scale as a valid instrument.

  • The purpose of this study was to identify the factors of school happiness of elementary students by implicit theory. For this purpose, 192 items for happiness were constructed based on 76 5th and 6th elementary students' free descriptions. Then 75 items were selected for preliminary factor analysis based on item appropriateness by evaluation of 28 elementary teachers. The happiness inventory composed 136 items was administered to 155 students and 36 items were selected based on exploratory factor analysis results. 4 factors-optimism, positive peer-relationship, self-esteem, consideration, and teacher-relationship-were extracted by principal component analysis. The confirmatory factor analysis indices indicated that 4 factor model of happiness was fit. The reliability(Cronbach's ${\alpha}$) was .996.
