  • The most widely used instrument to assess perceiving a calling, the CVQ(Calling and Vocational Questionnaire), is composed of three constructs: transcendent sermon, purposeful work, and prosocial orientation. Recently assessing perceiving a calling has received great attention and it is critical not only for job incumbents but also college students who are in the job search stage. The purpose of this study is to investigate measurement invariance of the Korean CVQ between employees and college students. 339 job incumbents and 252 college students participated in this study, and based on the multiple group confirmatory factor analysis from the structural equation model, we confirmed the measurement invariance between employees and college students at the scale level. Thus, the perceived calling scale is applicable to both employees and college students without biases. This study provided meaningful information in understanding calling, and we discussed limitations and future directions.

  • A new design approach for a delicate treatment of complex geometries such as a wing/body configuration is arranged using overset mesh technique under large scale computing environment for turbulent viscous flow. Various pre- and post-processing techniques which are required of overset flow analysis and sensitivity analysis codes are discussed for design optimization problems based on gradient based optimization method (GBOM). The overset flow analysis code is validated by comparing with the experimental data of a wing/body configuration (DLR-F4) from the 1st Drag Prediction Workshop (DPW-I). In order to examine the applicability of the present design tools, careful design works for the drag minimization problem of a wing/body configuration are carried out by using the developed aerodynamic shape optimization tools for the viscous flow over multiple-body aircraft geometries.

  • This paper derives noninformative priors for scale parameter of exponential distribution when the data are collected in multiple step stress accelerated life tests. We nd the objective priors for this model and show that the reference prior satisfies first order matching criterion. Also, we show that there exists no second order matching prior. Some simulation results are given and using artificial data, we perform Bayesian analysis for proposed priors.

  • Background: The relationship between risk factors and likelihood of occupational injury has been studied. However, what has been published has only provided a limited explanation of why some of the employees working in the same environment as other employees suffered a single-injury event, while other employees experienced multiple-injury events. This article reports on an investigation of whether artisanal and small-scale miners in Migori County of Kenya are susceptible to a single-injury or multiple-injury incidences, and if so, what underpinning parameters explain the differences between the single incident injured and the multiple incident injured group. Mine management commitment to safety in artisanal and small-scale mining (ASM) operations is also considered. Materials and methods: The research objectives were achieved by surveying 162 uninjured and 74 injured miners. A structured, closed-end questionnaire was administered to participants after the stratification of the study population and systematic selection of the representative samples. Results: The results showed that most injured miners suffer a single-injury incident rather than experiencing multiple-injury events, and laceration (28.40%) was the common injury suffered by the miners. The analysis showed that the risk factors for the single incident injured group were not similar to those in the multiple incident injured group. The research also found mine workers have low opinion about mine management/owners commitment to safety. Conclusion: The study concluded that mine management and miners need to be educated and sensitized on the dangers of this operation. Provision of safety gears and positive safety culture must be a top priority for management.

  • Purpose: This study was conducted to measure the levels of Health status, perceived stress, self-esteem, and achievement motivation and assertive behavior of adolescents. The relationships among these variables as well as predictors of health status were examined. Method: The sample was composed of 496 students (male: 195. female: 301) from 3 high schools in Seoul and Kyunggi-Do regions. The instruments used in this study were as follows: health status scale developed by Noh (1991), perceived stress scale developed by Park(1996), self-esteem scale developed by Rosenberg (1965), achievement motivation scale developed by Park(1986) and assertive behavior scale developed by Kim(1982). The reliability of the five instruments were examined using Chronbachs' a that ranged from, .63 to .90 in this study. The data were analyzed with the SAS program using descriptive statistics, t-test, ANOVA, Duncan multiple comparison, Pearson correlation coefficients, and stepwise multiple regression. Results: The results were as follows: 1. The mean score .of health status was 3.1, which was higher than the median of the instrument. 2. There were significant correlations of health status with self-esteem (r=.381. p=.0001), assertive behavior (r=.503. p=.0001), and perceived stress (r=-.352. p=.0001). 3. Stepwise multiple regression analysis showed that 34% of health status was affected by the level of assertive behavior (25%), self-esteem (7%), and perceived stress (2%). Conclusion: Based on these findings, assertive behavior and self-esteem appear to be specific important areas of future research as to better understand the health status of adolescents, and to develop health status-related interventions for them.

  • This study aims to create a model for predicting the number of extinguishment manpower to put out forest fires by taking into account the climate, the situation, and the extent of the damage at the time of the forest fires. Past research has been approached to determine the cause of the forest fire or to predict the occurrence of a forest fire. How to deal with forest fires is also a very important part of how to deal with them, so predicting the number of extinguishment manpower is important. Therefore predicting the number of extinguishment manpower that have been put into the forest fire is something that can be presented as a new perspective. This study presents a model for predicting the number of extinguishment manpower inputs considering the scale of the damage with forest fire on a scale bigger than 0.1 ha as data based on the forest fire annual report(Korea Forest Service; KFS) from 2015 to 2018 using the moderated multiple regression analysis. As a result, weather factors and extinguished time considering the damage show that affect forest fire extinguishment manpower.

  • Purpose: Recently as couples have only one or two children, they concern about their children's optimal health. Furthermore, as the basic principles of Korean traditional prenatal education (Taegyo) are supported by scientific evidence, and as increasing numbers of pregnant women are recognizing Taegyo refresh, the practice of Taegyo is growing. The purpose of this study was to identify the factors associated with the practice of Taegyo among pregnant Korean women. Methods: This was a cross-sectional, survey study of 228 pregnant women recruited at a health center in South Korea using a convenience sampling method. The instruments included the perception of Taegyo scale, the spouse's support scale, the self-confidence for infant care scale, and the practice of Taegyo scale. The data were analyzed using descriptive statistics and multiple regression analyses. Results: The results of the stepwise multiple regression analysis indicated that the following factors accounted for 26.5% of the variance in the practice of Taegyo: the perception of Taegyo, family income. Conclusion: Consequently, this result showed that the pregnant women were influenced by family income, spouses' support as requisite factors, and also they developed the level of self-confidence for infant care and the perception of Taegyo as self-care agency for the practice of Taegyo. The present study findings will add to the accumulated knowledge of health care professionals about the cultural factors involved in the practice of Taegyo and the traditional cultural beliefs and culture-specific health promoting behaviors of ethnic minority pregnant women to provide culturally competent care for them.
