The purpose of this study was to examine the structural relationships and influences of job embeddedness, job satisfaction, organizational commitment and burnout in childcare teachers who worked in daycare centers. The subjects in this study were 364 selected teachers who worked in daycare centers in South Jeolla Province. Structural equation modeling was used to analyze the collected data to determine the structural relationships and influences of the variables. The findings of the study were as follows: First, the job embeddedness of the childcare teachers exerted a positive influence on job satisfaction and served to bolster organizational commitment, but that had no direct impact on burnout. Second, the job satisfaction of the daycare teachers exercised a negative influence on burnout, whereas organizational commitment didn't affect burnout in a significant way. Third, job satisfaction turned out to have the complete mediating effects on the relationship between job embeddedness and burnout. but, that as for the mediating effects of organizational commitment produced no direct and indirect effects. So the variable turned out to have no mediating effects. Given the findings of the study, how to improve the job embeddedness of childcare teachers should be considered in detail to boost their job satisfaction and organizational commitment. As higher job satisfaction led to less burnout in the childcare teachers, it's suggested in this study that necessary legal and institutional measures should be taken to improve work environments to ensure the job stability of childcare teachers as childcare experts. 본 연구의 목적은 보육교사를 대상으로 직무착근도, 직무만족, 조직몰입, 탈진 간의 구조적 관계와 영향력을 밝히는데 있다. 전남 소재 어린이집에 근무하는 보육교사 364명의 자료를 수집하여 연구변인들 간 구조적 관계와 영향력을 확인하기 위해 구조방정식 모형으로 분석하였다. 분석결과, 첫째, 보육교사의 직무착근도는 직무만족에 긍정적인 영향을 미치고, 조직몰입을 증가시키지만, 탈진에는 직접적인 영향을 주지 않는 것으로 나타났다. 둘째, 보육교사의 직무만족은 탈진에 부적인 영향을 미치는데 비해, 조직몰입은 탈진에 유의한 영향을 주지 않음을 확인하였다. 셋째, 보육교사의 직무착근도와 탈진과의 관계에서 직무만족 매개효과는 완전매개를 보이고 있는 것으로 나타났으나, 조직몰입의 매개효과는 직접효과와 간접효과가 모두 나타나지 않아 매개효과가 없음을 규명하였다. 연구결과를 통해 보육교사의 직무만족과 조직몰입을 증진시키기 위해 직무착근도를 높이는 방안을 구체적으로 강구해야 할 필요가 있음을 제안하였다.

하정윤,장영준,이주영 한국생활환경학회 2015 한국생활환경학회지 Vol.22 No.4

The purpose of the present study was to explore the influences of unanticipated results from the 2014 Sochi Winter Olympic figure skating competition on the physiological and psychological responses of spectators. 15 males, who were all supporters of the figure skater Yuna Kim, participated in this study. They watched the figure skating performances of the final games in real time in Korea. Heart rate, chest and finger temperature were recorded for two hours every 5 s and eight emotions were assessed. The results showed that heart rate increased by 15±14 bpm (p<0.05) and finger temperature decreased by 4.9±2.4oC (p<.05) during Yuna Kim’s performance. Tension, depression, anger, vigor, and excitement were significantly higher in the after-values compared to the before-values (p<.05). Heart rate showed significant relationships with fatigue (r= -.519), boredom (r= -.612), and vigor (r= .544). These results indicate that emotional changes evoked while watching a sporting event induced acceleration in cardiovascular responses and vasoconstriction in peripheral vascular responses. It is suggested that accelerated tension and excitement while watching a sporting event stimulate sympathetic nerves along with causing blood concentration to the brain, which might result in the peripheral vascular constriction and the increase in heart rate.

하정윤,이지혜 교육종합연구원 2016 교육종합연구 Vol.14 No.1

This study was conducted to analyze the relationship between school principals’ management capacity and school effectiveness. Its focus was on “transformational leadership” and “the level of policy practice” as management capacity of school principals, and the academic achievement and school satisfaction of students were selected as a measurement criterion for school effectiveness. Using the third-year data of Gyeonggi Education Panel Study (GEPS), the study was designed as a Level-2 Hierarchical Linear Modeling (HLM), and the data of 53 regular high schools and 3,235 students were analyzed. The results of the analysis indicated that the standard deviation between school principals for the academic achievement and school satisfaction of students was 29.253% and 9.832%, respectively, and that the difference between school principals concerning the academic achievement and school satisfaction of students was statistically significant even after controlling for student-level variables. It was confirmed that, among the variables affecting the management capacity of school principals, the level of practicing the education policy made a statistically significant difference, which indicates that the higher the level of school principals practicing the education policy, the higher the academic achievement and school satisfaction of students. From the results of this study, it is necessary that they arrange more structured training courses and strengthen the capabilities of practice in order to enhance the school principals’ understanding of education policy and their practice levels. It is also suggested that they establish the standards and institutions for checking the capabilities of school principals practicing the education policy and use them in selecting and placing them.

하정윤,손준식,김영경,김교한,권태엽 한국고분자학회 2013 Macromolecular Research Vol.21 No.1

Establishing a durable bond with dental zirconia ceramic remains difficult. This study investigated the effect of heat treatment of primer-coated dental zirconia on the bonding durability of resin cement to the zirconia. Each of three types of primers (silane primer, acidic monomer-containing primer, and silane/acidic monomer containing two-component primer) was applied to sandblasted zirconia surfaces. For subsequent heat treatment, half were then put in a furnace for 60 min at 150 oC. All specimens were bonded with resin cement and aged using thermocycling (0, 5,000, and 20,000 cycles) prior to a shear test. The surface energy parameters of the zirconia were also calculated from the contact angle measurements based on the acid-base theory. The heat treatment enhanced the bonding durability of the zirconia pre-treated with the silane primer and the acidic monomer-containing one, the shear test and Weibull analysis results showed that the former performed better than the latter. In contrast, the twocomponent primer-coated zirconia showed poor bonding durability after the heat treatment. The bonding performance was related to the surface characteristics of the zirconia. Thus, we suggest that heat treatment of zirconia pretreated with silane primer effectively improves bonding durability with resin cement.

본 연구는 예비유아교사의 핵심역량을 교육과정에서 효과적으로 강화하기 위해 필요한 정보를 도출할 목적으로 수행되었다. 연구목적을 달성하기 위해 K-CESA를 활용하여 예비유아교사의 핵심역량을 진단하고, IPA분석을 실시하였다. 그 결과 첫째, 예비유아교사의 핵심역량은 대인관계, 자기관리, 종합적사고력, 글로벌역량, 의사소통역량, 자원․정보․기술의 활용역량 순으로 나타났다. 둘째, 예비유아교사의 핵심역량 수준을 전국 4년제 대학생과 비교한 결과, 예비유아교사가 4년제 대학생에 비해 대인관계역량과 자기관리역량에서 더 높은 수치를 보였다. 셋째, 예비유아교사의 학년별 핵심역량은 학년별로 상이했다. 넷째, IPA 분석을 통해 핵심역량의 중요도와 실행도에 대한 인식을 조사한 결과, 가장 중요하다고 인식한 것은 정서적 유대였고, 토론과 조정이 가장 낮았다. 실행도에서 가장 높은 수치를 보인 것은 직업의식이었고, 낮은 값을 나타낸 것은 글로벌화 이해였다. 학년별 인식 차이를 분석한 결과, 중요도에서는 토론과 조정 등 9개 하위요소, 실행도에서는 듣기 등 4개 하위요소에서 통계적으로 유의한 차이를 보였다. 다섯째, 예비유아교사의 인식수준을 IPA매트릭스로 구현한 결과, 유연성 및 적극성 등이 2사분면에 위치하였다. This study is conducted to draw the information required for effectively improving pre-service teachers’ core competence in the curriculum. To achieve the goal of the study, this study diagnosed their core competence utilizing K-CESA and investigated their perceptions about the importance and performance(IP) of the core competence. As a result of analysis, first, the pre-service teachers’ core competences included personal relations, self-management, comprehensive thinking skills, global competence, communication competence, application ability of resources, and information and technology. Second, comparing levels of the pre-service teachers’ core competences with that of four-year college students nationwide, the pre-service teachers had higher level in the competence of personal relations and the competence of self-management compared to the four-year college students. Third, the pre-service teachers’ core competences were different by students’ year. Fourth, as a result of an investigation on per-service teachers’ perceptions about the IP of core competences through an IPA analysis, they perceived emotional connection as the most important competence of the core competence whereas taking discussion and mediation the least important competence. Job consciousness was at the highest level in the performance while globalization understanding was at low values. In addition, as a result of an analysis of the difference in perception by students’ year, there were statistically significant differences in nine sub-factors such as discussion and mediation in the importance and four sub-factors such as listening in the performance. Fifth, as a result of realizing and IPA Matrix analysis of the per-service teachers’ perceptions level shown through the IPA analysis on core competences, flexibility and activeness were located on Quadrant II(effort for priority correction).
