The purpose of this study is to find out the effects of directors' leadership style and the type of decision-making on improving child care teachers' job satisfaction which is essential to operate high-quality nursing. The survey method was used for 184 child care teachers who work for child care centers. The collected data were analyzed using one-way analysis of variance and posteriori test to find out the differences in teachers' job satisfaction according to their recognition of directors' leadership and decision-making. The result showed that differences exist in child care teachers' job satisfaction according to the leadership and decision-making of directors as recognized by the teachers. The score of child care teachers' self-development, work, welfare & social stability related to job satisfaction hit the highest when directors' leadership type was efficiency-centered. Similarly, participatory decision-making type, which is the most ideal type, scored the highest in all sub-components of job satisfaction in the case of directors' type of decision-making. This implies that the directors who prefer positive leadership and democratic participatory decision-making type increase teachers' job satisfaction which will positively affect the child care centers' qualitative development.

Globally, the forest fires are a significant contributor of carbon dioxide and other greenhouse gases in the atmosphere. In this study, fuel load consumed by forest fire and emission of green house gases were analysed in the surface layer. For this, remaining fuel was collected and weighed with the species (Japanese red pine, deciduous) and the forest fire types (surface fire, crown fire) in the 51 forest fires. 8,361 kg/ha fuel load was consumed in deciduous forest damaged by surface fire, and 8,055 kg/ha, 12,333 kg/ha in Japanese red pine burned by surface fire and crown fire. The combustion ratios were 78, 59, and 90%, respectively. 15,856 kg/ha the green house gases such as $CO_2$, $CH_4$, $CH_4$ in deciduous forest burned by surface fire was emitted and 14,834 kg/ha, 22,709 kg/ha in Japanese red pine burned by surface fire and crown fire.

The purpose of this study was to investigate the effects of meditation therapy on stress relief and quality of life. The experimental group included 85 Sojucheon meditation members in Gwangju and Jeonnam, and the control group was a survey of 48 members including general office workers and beauty school students. One-way ANOVA was performed for the statistics of differences in study variables between the two groups. The results of the analysis showed a significant difference in stress, and the F test also showed a significant difference in quality of life. Therefore, most of the meditation practitioners have been found that meditation therapy has a positive effect on stress relief and quality of life. These results suggest that Sojucheon meditation therapy is effective in relieving stress and quality of life, and it can be said that it is sufficient to provide a reference of meditation therapy for psychological stability.

This study was to identify factors influencing satisfaction on clinical practice of dental hygienist students located in G, J region. The data was analyzed by t-test, Anova, Pearson correlation coefficient, and multiple regression using SPSS 21.0 program. There were significant in satisfaction of score(F=2.925, p<.05), perceive heath status(F=8.108, p<.001), satisfaction on department(F=8.198, p<.001). The relationship on peers with score(r=.277, p=.01) and perceive health status correlations with relationships on peers(r=.327, p=.01), The satisfaction on clinical practice had positive correlations with score(r=.127, p=.05), perceive health status(r=.226, p=.01), relationship on peers(r=.240, p=.01). The factors influencing satisfaction on clinical practice were satisfaction of relationship on peers, satisfaction of department, perceive health status. The results suggest that development of program to improve satisfaction on clinical practice of dental hygiene students.

This study was conducted to explore differences of major selection regret and reasons by major selection motivation, and differences of college life, employment goal, first job satisfaction among groups by major selection motivation and regret of college graduates. For this study, '2013 Year Graduates Occupational Mobility Survey' of KEIS was examined by cross-tabulation analysis and one-way analysis of variance. The results were as follows: First, in the case of major selection by intrinsic motivation, less regrets were given than extrinsic motivation. Second, the biggest reason of regret was 'difficulty of unemployment' in case of intrinsic motivation and 'not fit in aptitude' in case of extrinsic motivation. Third, there were differences of college life, employment goal, first job satisfaction among four groups by major selection motivation and regret.

The purpose of the study was to investigate middle school students' and teachers' perception of psychological learning environments as well as the differences between them. This study sampled 503 middle school students and the 16 teachers who taught them. 'Psychological Learning Environment Instrument by Science Teacher' was implemented to collect data. Frequency analysis and descriptive statistics, as well as t-test, ANOVA were used for basic analysis of data. There were statistically meaningful differences in students' perception of psychological learning environments by gender, science achievement, science preference and self-efficacy in science. However, there are no differences in teachers' perceptions of psychological learning environments by gender, age, career year and major. The difference between teachers' and students' perception of psychological learning environments was not large, showing no statistical significance. However, teachers' perceptions of psychological learning environments was a little higher than that of students.

The purpose of this study is to compare and analyze the recognition and preference of Korean traditional cookies and Japanese "Wagashi" by consuming patterns and demographic characteristics in order to suggest strategies for promotion of Hangwa, Korean traditional cookies. Consumer questionnaire survey was done to quantify 241 answers for Korean traditional cookies and 249 for Wagashi, and they were used for final analysis, frequency, t-test, One-way ANOVA, and regression analyses with SPSS 12.0. As a result, it was found that there were the differences of recognition by demographic factors and consuming patterns on the preference and recognitions. Especially in the demographic characteristics, there were differences in recognition by age and education levels for hangwa and by age for wagashi. According to the regression analysis, recognition affected preference for hankwa and wagashi.

최근 교사들의 잇단 극단적 선택으로 학교의 변화와 상황에 대한 문제의식이 사회적으로 날로 높아지고 있다. 교직에 대한 선호도가 급격히 떨어지고 교직 이직 비율도 빠르게 높아지고 있어 교육의 질을 걱정하기에 이르렀다. 드러난 문제가 원인의 하나일 수 있으나 많은 연구에서 교사들의 직무스트레스가 심각한 수준임을 밝히고 있고, 학교교육 현장에는 교사들이 조직에 몰입하기 어려운 다양한 문제들이 있음을 밝히고 있다. 그럼에도 교육현장에서는 학생, 교사들이 함께 성장할 수 있고 모두가 만족하는 교육 활동을 실현시키고 변화와 혁신을 통해 교육역량을 높이고자 지속적으로 노력하고 있다. 본 연구는 초등학교 교사의 직무스트레스와 감정 노동이 조직몰입에 미치는 영향을 조사 분석하고 두 변인 즉 직무스트레스와 감정 노동이 직무몰입에 미치는 영향에서 긍정심리자본의 매개 효과를 알아보는데 그 목적이 있다. 교사 직무스트레스 실태를 종합적으로 파악하고자 관계 요인, 업무요인, 정책 요인으로 나누어 분석(김종민 외, 2018. 경기도교육연구원)하고 특히 스트레스 요인 중 가장 비중 있는 감정 노동 부분은 분리하여 더 상세히 분석하고자 한다. 이를 위해 경기도, 경기도, 서울, 전라남도 소재 초등학교교사 500명을 대상으로 자료를 수집하여 SPSS 20.0 프로그램을 활용하여 변인들의 기술통계치를 산출하고자 한다. 초등교사의 인구통계학적 변인간에 유의한 차이가 있는지 확인하기 위해 t-검정과 일원배치 분산분석(ANOVA)을 실시한다. 그리고 연구에 포함된 변인들간의 상관계수를 산출하고 Baron과 Kenny(1986)의 절차에 따른 3단계 회귀분석과 부트스트래핑(bootstrapping) 기법을 적용하여 매개효과의 유의성을 검증하고자한다.

The design of experiments are used for optimal design of formed tools to machine automobile bearing rubber seal die, which is classified into the high precision rubber mold. The clearance angle, rake angle and the length cutting edge are considered as the factors. The cutting force is selected to be a characteristic value and compared with the mean tool wear and life by repeated experiments. The design of the experiment is based on the repeated one-way factorial design, which finds the significance of the factors and the best level to predict the tool life by using ANOVA and regression.
