  • The aims of this study were to organize whether the Kindergarten After School Specialized Art Program could be applicable to young children, and whether this program would be effective to the development of young children's art competence. This study consisted of two steps: development of the Kindergarten After School Specialized Art Program and examination of its impact on children's art competence. This study used a two-group pretest/posttest design. Statistical analyses employed for this study were descriptive analysis, ANOVA, and repeated measure ANOVA. The results were as follows. Firstly, the Kindergarten After School Specialized Art Program was developed based on a literature review relevant of current art education. Secondly, the experimental group revealed a significant improvement in four components, whereas the control group showed a significant, but slight improvement compared with the experimental group in only three components. Thirdly, in between group comparison, a competencies on the four components based on multiple-creative ability in the experiment group were higher than that of the control group and the difference between both groups was statistically significant. Therefore, the program seemed to be effective in the improvement of art competence and multiple-creative ability. In addition, recommendation for the future research about after school teachers' and parents' recognition of the Kindergarten After School Specialized Art Program and strategies for its application are suggested.

  • The major purpose of this paper to identify safety climate practices, and to find the affecting variables that influence to the difference in the level of safety climate between plants and employees. And this paper attempted to find the interventions for improving safety climate in the chemical plants. The questionnaires were developed from literature review, especially made by HSE(Health and Safety Executive) in the UK and distributed to managers and workers. The frequency analysis was applied for identifying the level of safety climate. The affecting variables(plant size, accident occurrence, accident experience, injury experience and severity, and length of employment) are tested through analysis of variance(ANOVA). The results of frequency analysis showed that both managers and workers recorded generally high level of safety climate, and the major underlying problems are inadequate H&S procedures/rules, pressure for production, and rule breaking. According to the outcomes of ANOVA, the variable 'length of employment' is the only variable which makes the level of safety climate different. From the survey of safety climate practice, this study finds the level of safety climate and three major underlying problems in safety climate factors of the responded plants, and presents two interventions for improving safety performance. Despite of these outcomes, the applied factors are remained questionable for reflecting as the best ones for identifying safety climate in the chemical industry. In addition, the bias caused by self-report exist in the reliability of the response, and the equivalent size of respondents.

  • In the field of defense, one-shot devices such as missiles are stored for a long period of time after they are manufactured, so it is essential to predict their storage life. A study was conducted to find the shelf life of a Li-ion battery used in one-shot devices. To do this, a Li-ion battery that has been used in weapon systems for more than 5 years was secured. A non-functional test was performed on the battery to check for external changes or failures. After the non-functional test, a discharge test was performed to measure the performance after storing it. Through the test, the performance was checked, including the initial charging voltage, discharge time, and battery temperature, and the trend of the change was identified. An F-test, One-way ANOVA, and regression analysis were performed to verify the aging, and the shelf life of the battery was estimated by an approximation formula that was derived through a regression analysis. As a result of the ANOVA, the p-value was less than the reference value of 0.05, and the performance of the battery decreased by more than 15% after a certain period of time. This change is assumed to result from the change in physical properties of the lithium polymer cell.

  • Both competent authorities and private entrepreneurs face plenty of risks when negotiating BTO(Build Transfer Operation) methods of PPI(Private Participations in Infrastructures) projects. Also, success and failure of projects largely depend on the concession agreement contract. In this study, for more efficient negotiation, major issues are examined, and quantitatively analyzed to find out not only the relationship but also the characteristics of which these issues share. Questionnaire research was conducted through both research and by experts who were divided into an ordering agency, design company and constructor. Characteristics of major issues were quantitatively analyzed using the Likert index method, ANOVA(ANalysis of VAriance) and AHP(Analytic Hierarchy Process) analysis. Case studies were examined in order to estimate construction cost, rates of return, government finance support, level of operation-revenues guarantees, estimating operational costs and usage fees. With these 6 items, relative priority, relative impression which is sensible to risk and extent of difficulty in presenting data which is objective were quantitatively analyzed by the ordering agency, design company and constructor groups. From the analysis, there were some similarities between the design company and constructor groups while there was less of similarities between the ordering agency and design company or constructor. The government is diversifying the methods of project promotion, and PPI project from infrastructure-centered to public culture facilities are being expand. The current study will provide not only supporting efficient negotiation but also revitalizing PPI projects.

  • This study aims to analyze the differences in performance according to various operation methods (direct management, public consignment, and private agency) of public sewage treatment facilities and derive the most efficient and high level of sewage treatment services to the public based on the research results. To this end, economic performance indicators (sewage treatment cost, sewerage rate) and social performance indicators (water quality, number of civil complaints) were selected, and cross-sectional analysis and longitudinal analysis were used to verify the difference between the averages of three or more groups through one-way ANOVA. As a result of the analysis, cross-sectional analysis, there was no difference in economic performance dimension according to the operating method, but in terms of social performance dimension, it was found that there was a difference according to the operating method. In the case of water quality indicators, the results were superior to those directly managed by public consignment and private agencies in the number of civil complaints. In the longitudinal analysis examining the improvement of performance indicators, there was no significant difference by operation method in most performance indicators. In order to improve the efficiency of public services and improve the service level, various approaches suitable for the characteristics of each service are required in addition to the logic of public consignment or introduction of private agency. In the future, when local governments promote public consignment or private agency, it is necessary to understand and promote the nature of the service, the specificity of each local government, and the needs of service users.
