This study was performed to evaluate suitability as orthodontic band cement by measuring the retentive bond strengths, change of retentive bond strengths by time and failure patterns of cements after removal of bands cemented with each two brands of zinc phosphate cements and glass ionomer cements using universal testing machine. Orthodontic bands were cemented with two brands of zinc phosphate cements and two brands of glass ionomer cements to the cervical line of crown portion in specimens involving forty extracted human molar teeth embedded in resin blocks. After the specimens were then stored in artificial saliva at 37℃ during 24 hours, tensile bond strength on bands of specimens using universal testing machine was measured. The retentive bond strength of cements was defined the strength required to initially fracture the cement bond holding the orthodontic bands to the tooth and cement failure pattern was assessed with the quantity of cement remaining on enamel. Prior to recementation, both the tooth and the inside of the band were carefully cleaned. Recemented specimens were subjected to 3000 thermocycles at a temperature differential of 50℃. Two temperature baths, one at 5℃ and the other at 55℃, were used. The dwell time in each bath was 15 seconds. The specimens were then stored in artificial saliva at 37℃. Retentive bond strength was tested on band cemented after 2 weeks. Cement failure pattern was also assessed. The results were as follows: 1. No significant difference in retentive bond strength was found among all cements. 2. The effect of time on retentive strength of the zinc phosphate cements was not appeared. 3. The retentive strength of the glass ionomer cements was increased with time(p<0.01). 4. In cement failure patterns, zinc phosphate cement was below 30 percent and glass ionomer cement was about 50 percent(p<0.01). The above results suggest that retentive bond strength between zinc phosphate cements and glass ionomer cements is similar. It is suggested that in fluoride releasing glass ionomer cements, cement failure pattern reduce the possibility of enamel decalcification. Thus, this results suggest that glass ionomer cement can be regarded as more effective enamel protective orthodontic cement comparing to zinc phosphate cement.

중학생의 마인드셋이 학업적 자기효능감을 매개로 학업성취도에 미치는 영향: 저소득층 여부에 따른 다집단분석

김숙인(金淑仁),신태섭(申泰燮) 서울대학교 교육연구소 2020 아시아교육연구 Vol.21 No.3

본 연구의 목적은 중학생의 마인드셋이 학업적 자기효능감을 매개로 학업성취도에 미치는 영향을 확인하고, 학생들의 저소득층 여부에 따른 모형 차이를 검증하는 것이다. 이를 위해「경기교육종단연구(GEPS)」2016년 조사의 중학교 2학년 자료를 가구 소득에 따라 저소득층 489명, 비저소득층 4,842명으로 분류하여 분석을 실시하였다. 먼저 구조방정식 모형 분석을 통해 변인들 간 구조적 관계를 검증하였으며, Bootstrapping 방법을 사용하여 매개효과의 유의성을 검증하였다. 이후 다집단분석을 실시하여 저소득층 집단과 비저소득층 집단 간의 모형 차이를 검증하였다. 분석 결과, 첫째, 중학생의 고정 마인드셋이 학업성취도에 유의한 부적 영향을 미치는 직접효과와 학업적 자기효능감을 매개로 영향을 미치는 간접효과가 확인되었다. 둘째, 다집단분석 결과, 수학 과목에서 고정 마인드셋이 학업적 자기효능감을 거쳐 학업성취도에 영향을 미치는 경로에 두 집단 간 통계적으로 유의미한 차이가 나타났다. 저소득층 집단의 경우 비저소득층 집단과 달리 고정 마인드셋이 수학 학업성취도에 유의한 영향을 미치지 않았다. 또한 저소득층 집단의 경우 비저소득층 집단에 비해 학업적 효능감이 학업성취도에 이르는 경로 계수가 더 높았다. 이를 통해 본 연구는 저소득층 학생들의 경우 수학 학습에서 효능감, 정서, 동기 등의 정의적 영역이 학업성취도 증진에 중요한 부분임을 시사한다. This study aimed to identify the impact of a middle school student"s fixed mindset on academic achievement and to examine the model differences depending on students’s SES. For this purpose, data of 5,543 middle school second grade students in Gyeonggi Education Penal Study 2016(GEPS 2016) were used for analysis. SEM analysis and bootstrapping was performed and multi-group analysis was conducted to confirm the difference in model between low-income and non-low-income groups. The main results were as follows. First, significant difference was found between two groups in the path from academic self-efficacy to academic achievement. Second, there was a statistically significant difference between the two groups on the way in mathematics. In low-income group, fixed mindset did not significantly affect the achievement of mathematics. This study suggests that in the case of low-income students, learning-affective domains such as self-efficacy, emotion, and motivation are important in improving academic achievement.

일본의 방과 후 활동 정책과 대학과의 연계 사례

김숙이 한국방과후학교학회 2022 방과후학교연구 Vol.9 No.3

우리나라에서는 대학교육에서 정규 교육과정만큼 다른 다양한 활동을 중시하고 있다. 그 중 방과 후 활동은 대학과 지역사회와의 연계가 체계적으로 도입되어야 할 필요성에 대한 관심이 증폭되고 있다. 이에 본 연구는 일본의 방과 후 활동 정책과 대학에서의 방과 후 운영 사례를 고찰함으로써, 향후 우리나라 대학 방과 후 활동에 대한 정책적 시사점을 도출하기 위한 목적으로 수행하였다. 이러한 연구 목적을 가지고 방과 후 활동과 교과 외 활동의 개념을 고찰하고, 일본 방과 후 활동 정책 현황을 파악하였고, 대학과 연계한 방과 후 운영되는 사례로는 니시큐시대학, 시즈오카산업대학, 세이센여대, 릿쇼대학 등을 분석하였다.

Objective: The purpose of this study is to analyze the effects of early childhood teachers’ personality and grit on creativity. Methods: The subjects of study were 310 teachers at daycare centers in Seoul, Gyeonggi, and Incheon. The data collected through the questionnaire survey were analyzed by a structural equation model. Results: As a result of analyzing the structural relationship between early childhood teachers’ personality, grit, and creativity, it was found that their personality had a positive effect on their grit and creativity. Also, their grit was analyzed to have a positive effect on their creativity. As a result of verifying the mediating effect of grit on the relationship between the teachers’ personality and creativity, the grit was found to positively mediate their personality and creativity. In particular, it was shown that the indirect effect on the creativity through the grit was greater than the direct effect on the grit. Conclusion/Implications: The above results suggest that it is necessary to improve the grit in order to inhance the creativity of early childhood teachers.

This study aimed to develop standard items for the Korean Dental Hygienists' Licensing Examination; these items were also earmarked for use in developing the curriculum for dental hygienists, and in writing a job description, based on a job analysis using the Developing A Curriculum Method (DACUM). It also aimed to understand the significance and frequency of task elements that dental hygienists perform. Data were collected by means of a mail survey, in the form of self-entry, from a sample of dental hygienists registered with the Korean Dental Hygienists' Association. In all, 260 responses were analyzed. The tasks of dental hygienists were divided into four categories, 93 tasks, and 494 task elements. There were 281 elements (61%) that scored higher than 3.5 in significance, in the 4-scale items, and 480 elements (98%) that scored higher than 3.0. There were 30 elements (6%) that scored higher than 3.5 in frequency, and 140 elements (29%) that scored higher than 3.0 in frequency. Overall, 130 out of 494 elements (27%) scored higher than 3.0 for both significance and frequency. Therefore, those 130 elements should be included as items in the Korean Dental Hygienists' Licensing Examination. The results can also be used for curriculum development and as the basis of a job description for dental hygienists.
