  • Purpose: This study was conducted to develop a teacher-efficacy scale which is adequate for heath education teachers. Method: A preliminary questionnaire was made based on the hypothetical factors. A total of 364 health education teachers answered to the preliminary test, and the potential factors of teacher-efficacy were checked out by exploratory factor analysis (EFA). In the main test 378 health education teachers answered, the factor structure was drawn by EFA, and confirmatory factor analysis (CFA) was conducted to test and the fitness of the factor model. Results: Through the preliminary test, 5 potential factors were found, which were instruction, health-service, administrative task, interpersonal relationship, and community connection. Also, 48 items were reduced to 31 items. Through the main test, from the 34 items were extracted 4 factors with 24 items, And then teacher-efficacy scale was developed, which included the subscales of instruction efficacy, health-service efficacy, task-interpersonal efficacy, and community connection efficacy. Conclusion: Different from that for other subject teachers, the factor structure for health teachers had 4 factors with 24 items. The scale developed in this study is consistent with health teachers' work areas, and for this reason, has significance as a adequate and valid scale to measure teacher-efficacy of health education teachers.

  • The purpose of the present study is to explain the effects of academic self-efficacy, self-regulated learning and online task value on academic achievement and learning transfer in corporate cyber education. 202 students who completed S corporate's cyber courses in 2007 and responded to all survey participated in this study. A hypothetical model was proposed, which was composed of academic self-efficacy, online task value and self-regulated learning factors as prediction variables, and learning transfer as well as academic achievement factors as outcome variables. The results of this study through regression analysis as follows. First, learners' academic self-efficacy, self-regulated learning and online task value predict learners' academic achievement significantly. Second, except for academic self-efficacy, learners' self-regulated learning and online task value predict on learners' learning transfer significantly. Third, academic achievement plays a role as mediating value in predicting academic achievement by online task. It implies that learners' academic self-efficacy, online task value and self-regulated learning which predict learners' academic achievement and learning transfer should be considered in developing strategies for the design and operation of cyber courses.

  • 이 연구는 텔레서비스가 개인의 통행행태 및 교통수요에 미치는 영향을 분석하기 위한 것이다. 먼저 개별행태 모형에 기초한 가구원별 통행통신행태조사를 실시하고, 이 분석결과를 바탕으로 서로 상이한 업무행태를 보이고 있는 9개의 군집이 분류되었다. 다음으로 "가설 시나리오"기법을 이용하여 텔레서비스에 의한 교통수단의 대체 가능성을 추정하였다. 개별 군집 중 "가정주부"와 "노년/무직자"의 경우 향후 텔레서비스의 활용에 어려움 등, 정보화사회에서 소외될 가능성이 높을 것으로 예측되었다. 텔레서비스로의 전이확률을 추정한 결과 은행이나 관공서업무와 같이 교류되는 정보종류가 텍스트나 데이터와 같이 단순한 형태일 경우 높게 나타났다. 이러한 연구결과를 근거로 서울시의 경우 텔레서비스에 의하여 향후 일일 약 7.6%의 통행수요가 대체될 수 있을 것으로 예측되었다.

  • complexity in atmospheric environment coupled with shoreline and complex terrain often causes local variations of meteorology that are distinct from those representative over larger surrounding area, These kinds of local variations are less significant in usual long-term environmental impact analyses dealing with continuous plume. The variations could however be crucial in predicting dispersion of toxic substance released in a relatively small area for a short duration. In the present paper the effects of spatial and temporal resolution of diagnostic wind field on the dispersion of the released substance are investigated by using a puff model. A hypothetical release scenario assumes that a substance is released from a location in the Yochon Industrial Estate and passively dispersed within a few-kilometer distance for an hour. The results show that diagnostic analysis could resolve more spatial variations to some extent by employing smaller grid size. The peak concentrations and puff trajectories obtained from spatially -and/or tmeporally -varing diagnostic wind field are found appreciably different from those obtained from uniform wind field. Attention to high-resolution wind field in the both spatial and temporal spaces is called in the consequence analysis of toxic substance release.

  • This study investigated the pathways of factors affecting 173 employed mothers' second childbirth plans. Participants were all employed working mothers with an infant under 10 months old. The hypothetical model used in this research proposed that workplace childcare support, social support, value of children and parenting stress of employed mothers will directly affect second childbirth plans. Additionally, workplace childcare support, social support, value of children, marital satisfaction and job satisfaction will indirectly influence second childbirth plans as a result of parenting stress. The results of this research demonstrated that value of children and parenting stress were the factors which directly affected second childbirth plans of employed mothers. In addition, workplace childcare support, social support, marital satisfaction and job satisfaction indirectly influenced second childbirth plans as a result of parenting stress. This study suggests the need for the establishment and development of workplace childcare support and the need for enhancing the value of children. This research further suggests the need for policies aimed at increasing psychological well-being and decreasing parenting stress for working mothers who are contemplating second childbirth plans.

  • The purpose of this study was to find pathways among factors that distinguish the mothers' intention to have a second child. As for factors affecting the childbirth intention of mothers, this study aimed to explore pathways from fathers' participation in childrearing to intention of second childbirth as mediating variables, maternal parenting stress and marital satisfaction. This study used the third wave data of the Panel Study of Korean Children (PSKC) that is a national-representative birth-cohort study. Among the 1,802 participants of the PSKC, 717 mothers who have a husband/partner and only one child have responded a decided intention of second childbirth. SPSS 19.0 and Amos 19.0 were used to implement exploratory analyses of predictors and test path models. Results showed that the hypothetical model assuming a path from paternal involvement in childrearing to mothers' intention of second childbirth, mediated by maternal parenting stress and marital satisfaction fitted the data of working mothers and non-working mothers well. The results suggest policies focusing on internal characteristics of mothers and dynamics in the family.

  • Objectifying claims filed during the warranty period, analyzing the current circumstances and improving on the problem in question is an activity worth doing that could reduce the likelihood of claims to occur, cut down on the costs, and enhance the corporate image of the manufacturer. Existing analyses of claims are confronted with two problems. First, you can't precisely assess the risks of claims involved by means of the value of claims per 100 products alone. Second, even in a normal state, the existing approach fails to capture the probabilistic conflicts that escape the upper control limit of claims, thus leading to wrong control activities. To solve the first problem, this paper proposed that a time series detection concept where the claim rate is monitored based on the date when problems are processed and a hazard function for expression of the claim rate be utilized. For the second problem, this paper designed a model whereby to define a normal state by making use of PID (Proportion, Integral, Differential) and infer by way of a fuzzy concept. This paper confirmed the validity and applicability of the proposed approach by applying methods suggested in the actual past data of warranty claims of a large-scaled automotive firm, unlike hypothetical simulation data, in order to apply them directly in industrial job sites, as well as making theoretical suggestions for analysis of claims.

  • A simple measure of uncertainty importance based on normalized metric distance to quantify the entire change of cumulative distribution functions (CDFs) has been developed for use in probability safety assessments (PSAs). The metric distance measure developed in this study reflects the relative impact of distributional changes of inputs on the change of an output distribution, white most of the existing uncertainty importance measures reflect the magnitude of relative contribution of input uncertainties to the output uncertainty. Normalization is made to make the metric distance measure a dimensionless quantity. The present measure has been evaluated analytically for various analytical distributions to examine its characteristics. To illustrate the applicability and strength of the present measure, two examples are provided. The first example is an application of the present measure to a typical problem of a system fault tree analysis and the second one is for a hypothetical non-linear model. Comparisons of the present result with those obtained by existing uncertainty importance measures show that the metric distance measure is a useful tool to express the measure of uncertainty importance in terms of the relative impact of distributional changes of inputs on the change of an output distribution.

  • Purpose: This study was done to elicit basic data for effective human resource management by identifying the relationships among job embeddedness, emotional intelligence, social support, and the turnover intention of Nurses. Methods: Research design was to build a hypothetical causal model between variables and to verify its fitness. The sample for this study was 283 nurses with careers of more than 6 months in one hospital of more than 800 beds located in Seoul. They agreed in writing and this study was approved by the Institutional Review Board. Data were analyzed using SPSS 18.0 and AMOS 18.0 program. Results: Differences in general characteristics for the variables were significant for age, marital status, education, work experience, job title, income, and department. Job embeddedness, emotional intelligence and social support were significantly correlated to turnover intention. Job embeddedness to emotional intelligence and social support showed positive effects and a negative effect to turnover intention. Emotional intelligence to turnover intention showed a positive effect, but social support was not significant. Conclusion: Organizations should provide ways to minimize voluntary turnover of a competent workforce and demonstrate their competency. Also it should develop training and management programs to effectively utilize emotional intelligence.

  • Purpose: The purpose of this study was to identify the mediating effect of hope and depression applied on the influence of social stigma on suicidal ideation of 108 HIV infected males. Methods: This study was a descriptive, crosssectional design that used a survey approach. Data collection was one-on-one interviews by a counseling nurse from July 2012 to January 2013. The survey included questions about social stigma, hope, depression, and suicidal ideation. Results: Fitness of the hypothetical model was appropriate ($x^2/df=1.97$, TLI=.97, CFI=.98, RMSEA=.07, SRMR=.04). Social stigma had no direct effect on suicidal ideation but had a significant indirect effect on suicidal ideation via hope and depression. Hope had a mediating effect the relationship between stigma and depression but no direct effect on the relationship between stigma and suicidal ideation. Hope had an indirect effect on suicidal ideation via depression. Stigma and hope accounted for 41% of depression was where as suicidal ideation was explained 56.3% by depression, hope, and stigma. Conclusion: In order to reduce depression and suicidal ideation of HIV infected people, stigma improving strategies are required. And hope intervention for HIV infected people may decrease their suicidal ideation and depression.
