  • The purpose of this study was to develop a scale to assess a Korean home environment for middle childhood children. The subjects were 283 mothers of 6- to 8-year-old children in Korea. The method for data analysis included Mean, SD, $x^2$, Cramer's V, factor analysis, Pearson correlations, and Cronbach's $\alpha$. As a result, 45 items of the scale were found to be satisfactory in terms of item distribution and item discrimination(Cramer's discriminant coefficients ranged from .256-.615). Four factors with 21 items were extracted from the factor analysis. Subscales were 'academic stimulation(9)', 'acceptance(4)', 'child-centered environment(4)', 'basic care for daily routine(4)'. Analysis of the relation of this scale to SES, MC-HOME, and children's developmental functioning(cognitive, language, and social) showed acceptable concurrent validity. Internal consistency of this scale was high, including internal reliability of subscales. These results confirm this scale as a valid and reliable measure of the Korean home environment for middle childhood children.

  • Roll-to-roll based manufacturing plays an important role in producing devices at high speed with lower production cost in printed electronics and publishing industry. Web lateral control is one of the most important factors in improving the quality of product and contributes a considerable point in making devices at micrometer-level accuracy. In recent years, most algorithms proposed for web lateral control base on the Shelton‘s model for designing the feedback control system using the PI controller. Experimental results showed that the existing models do not fully describe the characteristics of the lateral dynamics for some typical operating conditions and so result in poor control algorithms. In this paper, a new lateral control algorithm is proposed for web lateral control system based on back-stepping approach. The outcome of this study proves the reliability throughout simulation results in Matlab/Simulink and comparison with the algorithms based on the existing results.

  • In this paper, we provide an overview of financial development in Vietnam. Particularly, a new approach of this study is to measure financial development through improvements in depth, efficiency and access of the banking system and stock market. Further, the study examines the factors significantly affecting financial development in Vietnam. The data are collected in Vietnam, an emerging country with a limited financial development. We employ the Autoregressive Distributed Lag (ARDL) approach, which generates a high reliability and suits data characteristics of emerging countries like Vietnam. We observe that Vietnam's banking system plays a key role in supplying credits to the economy while the nascent stock market at a limited size shows its potential for a considerable growth in the future. We also find the influential determinants of financial development in Vietnam including real estate market (RE), economic growth (EG), consumer price index (CPI), and global financial crisis (GFC). These findings are essential for Vietnamese authorities in providing practical solutions in order to build a sustainable and synchronous financial development. They are also first empirical evidence relating to an overview of financial development in an emerging country, so they are not only valuable to Vietnam but also crucial to other emerging economies.

  • Purpose: The purposes of the study were 1) to examine what relationships exist between PTE(perceived treatments effect) and PPS (perceived physical suffering) as the independent variables and hope as the dependent variable and 2) to examine whether PTE and PPS predict hope in cancer patients in their post-operative period within the Stotland's hope theory. Method: The Visual Analog Scale was used for measuring PTE and PPS and the Kim & Lee's Hope Scale which had acceptable reliability and validity was used for measuring hope. The data was collected from 38 hospitalized cancer patients who were in the post-operative period with a convenient sampling method. Result: There was a significant positive relationship between hope and the PTE in the low PTE group. There was a significant negative relationship between hope and the PPS in the low PPS group. There were no significant relationships between hope and the PTE in the high PTE group, and between hope and the PPS in the high PPS group. And the PTE explained hope with 71.2% of the variance in the low PTE group. Conclusion: PTE in the low PTE group and PPS in the low PPS group were identified as the factors to explain hope.

  • The purpose of this study was to develop a ratio scale to measure job satisfaction of nurses and health workers in health centers. Of the 224 health centers in Korea, 105 were drawn as the sample using disproportion리 stratified random sampling. The data collection period was from May 1 to June 30, 1990 and 771 nurses and health workers working at 75 health centers participated. Subjects were instructed to rate, according to the level of satisfaction, from one to four points, 42 items revised from the tool made by Stamps et. al. (1978). The internal consistency reliability of the tool was measured by Cronbach $\alpha$ and the corrected item-total correlation coefficient. As a result of the item analysis, one item was excluded since the item had negative correlation with total items. As a result of factor analysis on the 41 items with varimax or above. Labeling and numbering of 6 factors were as follows ; factor 1 (8 items) ; Professional status of job. factor 2 (6 items) ; Interaction. factor 3 (8 items) ; Autonomy. factor 4 (8 items) ; Administration. factor 5 (7 items) ; Pay. factor 6 (4 items) ; Job(Task). Further studies are needed to identify the relationship between this tool and the effectiveness of the health center and more research is needed for generalization.

  • Purpose: The purpose of this study was to develop a measurement tool of nurse's turnover intention. Methods: Data were collected from questionnaires completed by 678 nurses who worked in 3 university hospitals in South Korea and analyzed using the SPSS 18.0 and AMOS 18 programs. Thirty-seven preliminary items were selected from 161 basic items extracted via a literature review and in depth interviews with 6 hospital nurses. Three steps with factor analysis were undertaken to verify the reliability and validity of the preliminary instruments. Finally, confirmative factor analysis was carried out. Results: As a result of the analysis, 3 factors including 10 items were selected. Cronbach's Alpha for the 10 items was .83, for job satisfaction (4 items), .78, for interpersonal relationships (3 items), .80, and for work performance (3 items), .74, which was stable. Conclusion: This study is meaningful because through it a scale reflecting Korean culture was developed to measure turnover intention in nurses. Further studies that test the psychometrics of this scale in more diverse samples are warranted.
