  • The objective of this study was to investigate how to improve job satisfaction for dietitians and nutrition teachers by identifying influencing factors in Daejeon and Chungnam Province, South Korea. A survey was conducted among school foodservice dietitians and nutrition teachers from selected primary, middle and high school in the area. This survey consisted of general characteristics, status of their job, job satisfaction, work satisfaction and work performance. In this study we found current state of general characteristics and status of their job according to frequency analysis and the level of work satisfaction, work performance and job satisfaction using descriptive statistics. The t-test, ANOVA and Duncan-test were also conducted in order to searching for tendency of job satisfaction according to the general characteristics and the status of their job. Pearson's correlation was carried out in order to find correlation with job satisfaction. Also, factors, which influenced job satisfaction according to regression analysis, were drawn. We describe the difference of job satisfaction between irregular dietitians and nutrition teachers as well. Besides we discussed the improvement of dietitians' (nutrition teachers') work environment to raise their job satisfaction through this study.

  • In order to solve the problem of false terrains caused by environmental interferences and tunneling effect in the conventional multi-beam seafloor terrain detection, this paper proposed a seafloor topography detection method based on fast two-dimensional (2D) Censored Mean Level Detector-statistics Constant False Alarm Rate (CMLD-CFAR) method. The proposed method uses s cross-sliding window. The target occlusion phenomenon that occurs in multi-target environments can be eliminated by censoring some of the large cells of the reference cells, while the remaining reference cells are used to calculate the local threshold. The conventional 2D CMLD-CFAR methods need to estimate the background clutter power level for every pixel, thus increasing the computational burden significantly. In order to overcome this limitation, the proposed method uses a fast algorithm to select the Regions of Interest (ROI) based on a global threshold, while the rest pixels are distinguished as clutter directly. The proposed method is verified by experiments with real multi-beam data. The results show that the proposed method can effectively solve the problem of false terrain in a multi-beam terrain survey and achieve a high detection accuracy.

  • 본 연구는 D대학 아동영어교육학과 재학생 88명을 대상으로 자아존중감, 전공만족도, 진로정체감 및 대학생 활적응과의 관계를 조사하였으며, 수집된 자료는 IBM SPSS Statistics 22를 이용하여 신뢰도분석, 요인분석, 빈도분석, 기술통계량, t-검정과 분산분석, 상관분석, 다중회귀분석을 실시하였다. 자아존중감, 진로정체감, 전공만족도 및 대학생활 적응 간에는 모두 유의한 정적인 상관관계를 보였으며, 대학생활과 가장 상관관계가 높은 것은 자아존중감, 전공만족도, 진로정체감 순이었다. 대학생활적응에 영향을 미치는 것은 자아존중감(${\beta}=.664$, p=.000)과 전공만족도(${\beta}=.349$, p=.000)이었다. 아동영어교육학과 재학생의 대학생활 적응력을 높이기 위해서는 자아존중감, 전공만족도를 증진하기 위한 아동영어교육학과 특성에 맞는 체계적이고 구체적인 프로그램이 필요할 것으로 사료된다.

Stepwise multiple regression analysis showed that Self Care Agency was a predictor of Self Care Behavior and accounted for 28% of the variance. Self Care Agency account for 31% of the variance in Self Care Behavior in the high school girls. Self Care Agency and Hope accounted for 27% of the variance in Self Care Behavior in High school boys. Conclusion: Self Care Agency accounted for variance in Self Care Behavior in these high school students. Therefore it is necessary to develop nursing interventions to increase Self Care Agency in high school students in order to increase the Self Care Behavior.

  • 본 연구는 고등학생의 고카페인 에너지음료 섭취 실태와 부작용 경험을 파악하기 위한 실시된 조사연구이다. 수집된 245명의 자료를 SPSS 18로 기술통계와 ${\chi}^2-test$를 실시하였다. 본 연구대상자의 79.5%가 고카페인 에너지음료를 마신 경험이 있었다. 고카페인 에너지음료 섭취 후 50.6%가 부작용을 경험했으며, 부작용 중 가슴 두근거림이 가장 많았다. 일반적인 특성 중 한 달 용돈(p=.019)과 음주 여부(p=.033)에 따라 고카페인 에너지음료 섭취 경험과 유의한 차이가 있었고, 성별(p=.001)과 건강상태(p=.006)에 따라 부작용 경험과 유의한 차이가 있었다. 또한 고카페인 에너지음료 섭취 실태에 따른 부작용 경험과의 차이는 고카페인 에너지음료의 섭취 이유(p=.040)와 섭취 시기(p=.005)에 따라 유의한 차이가 있었다. 고등학생들의 고카페인 에너지음료의 소비를 줄이기 위해서는 고카페인 음료의 판매를 제한할 수 있는 정책적인 방안이 마련되어야 할 것이며, 학생 스스로가 조절할 수 있는 역량 함양을 위해 지속적인 건강교육이 필요할 것이다.

  • This study was conducted in order to assess the effect of variables influencing Korean baby-boomers' welfare consciousness. For this purpose, data from the $8^{th}$ supplementary survey of the Korea Welfare Panel in 2013 were analyzed. The subjects of analysis were 2,035 people who were born between 1955 and 1965 whose welfare panel data did not have missing values for the variables of the research model. According to the results of analysis, first, when the descriptive statistics of the major variables were analyzed, those showing a relatively high mean score among the sub-factors of the baby-boomers' welfare consciousness were 'expansion of expenditure for public assistance' (mean 3.65, SD .557), 'expansion of expenditure for social insurance' (mean 3.53, SD .646), and 'expansion of expenditure for social services' (mean 3.26, SD .424). The mean score of the baby-boomers' overall welfare consciousness was relatively high as 3.45 (SD .428), advocating the expansion of welfare expenditure. Second, the independent variables influencing the baby-boomers' welfare consciousness was found to have explanatory power of 12.9%. In the results of regression analysis, variables found to have a significant effect were gender (B=.100, t=2.573, p<.01), personal responsibility for poverty (B=-.151, t=-3.635, p<.01), social responsibility for poverty (B=.149, t=3.437, p<.001), and recipient's laziness (B=.251, t=6.578, p<.001). Based on these results were discussed major relevant policies.

  • As workplace incidents has been being declining in Korea, there is criticism of the effectiveness of occupational safety policy implementation. It is unknown that which policy target group needs to be targeted to yield effective injuries prevention. The purpose of this paper is to analyze and reveal the policy intervention group with a high priority in terms of industrial incident prevention and the related investment cost. A Policy Priority Model(PPM) is composed of 6 indicators regarding influences of both the incident reduction and the cost reduction. Z-score analyses are used to confirm the high policy priority area or policy target group. Overall, workplace with worker below 50 persons, construction site with the sales of more than a hundred million won, workplace with relatively small percentage of female employees and relatively higher percentage of older worker should be prioritized to reduce workplace injuries. This paper provides an analytic way that can be used to decide the policy priority workplace in order not only to reduce work-related injuries&illnesses and the related investment cost but to further lessen the related societal costs.

  • Purpose: In South Korea, suicide mortality has rapidly increased, so it has become a major public health concern. Multicultural adolescents are regarded as a high-risk group due to their situation. In this study, we compared the prevalence and risk factors of suicide ideation between Korean and multicultural adolescents. Methods: Data from the eleventh Korean Youth Risk Behavior Web-based Survey (2015), collected by the Korean Centers for Disease Control and Prevention, were statistically analyzed using the descriptive statistics and multivariate logistic regression. The total participants were 63,376 in numbers. They were composed of 62,649 (98.9%) Korean and 727 (1.1%) multicultural adolescents. Results: I found that the prevalence of suicide ideation was significantly higher among the multicultural adolescents (15.8%) compared with those of Korean (11.3%). The risk factors of suicide ideation in the Korean group were co-residence without family, poor perceived health status, depressive mood, high stress level, poor perceived happiness level, and experience of violence. Conversely, the risk factors of the multicultural group were smoking, depressive mood, and experience of violence. Conclusion: These findings suggest that appropriate and practical prevention strategies should focus on psychological and environmental factors in order to prevent suicide ideation and reduce suicide behavior in Korean and multicultural adolescents.
