Methylmethacrylate monomer (MN) bone cement is commonly employed in orthopedic procedures, particularly total hip and knee replacement, to anchor prosthetic devices to bone. Numerous cardiopulmonary complications can occur just after injection of MN. And MN produces direct relaxation of vascular smooth muscle in vitro. The purpose of this study was to determine if MN could have relaxation effect in tracheal smooth muscle too. Methods: Each ring of rat trachea was suspended on wire supports in a bath with Tris Tyrode solution. Dose response curves of MN were recorded after contraction of tracheal ring with acethylcholine (Ach) 10-5 M or cabachol (Cch) 10-8 M. MN was administered in denuded tracheal rings and compared it's effect with intact tracheal rings to see the effect of epithelium for contraction. And MN dose response curves were recorded after pretreatment of nitric oxide synthase inactivator (L-NAME), muscarinic receptor blocker (atropine), beta-adrenaline receptor blocker (propranolol), adenylyl cyclase inhibitor (SQ22536) respectively. The effects of MN on cellular Ca2+ and K+ migration in rat tracheal preparations were studied. Results: MN significantly inhibited acetylcholine or carbachol induced contractions of tracheal rings dose-dependently (P < 0.05). This relaxation effect of MN was not recovered in denuded tracheal rings. And pretreatment with L-NAME, propranolol, atropine, SQ22536 or tetraethylammonium respectively did not recover the relaxation effect of MN. MN inhibited both intracellular calcium release and extracelluar calcium influx. Conclusions: The relaxation effects of MN on rat tracheal rings are not related with epithelium, nitric oxide, muscarinic, or beta-adrenergic receptor. Methylmethacrylate monomer inhibits both intracellular calcium release and extracelluar calcium influx.

길현주,이효인 한국사회과교육학회 2019 시민교육연구 Vol.51 No.4

This study aims at figuring out the development as training lecturers and teachers through the course to educate lecturers for training Integrated Social Studies teachers. Integrated Social Studies was a new subject introduced into the revised National Curriculum in 2015 and the training started as there had been no teachers with experience of teaching the subject. Training lecturers with different majors have grown their abilities as lecturers through collaborative development of training programs for teachers of integrated social studies. Firstly, lecturers were motivated by their peer training lecturers who tried to practice good teaching with zeal. Secondly, training teachers helped form relations consisting of trust, support, and respect within the newly created network of lecturers. Based on these stable emotional backgrounds, they could expand their own perspectives and accept unfamiliar things. Third, they could apply knowledge and methods from the workshop for teachers of Integrated Social Studies to the training and their own classes. The knowledge and methods acquired from the workshop were completely embodied to them. Fourth, after practicing acquired teaching methods in the actual training and in their own lives as teachers, the experiences of reflection could be used as feedback for improving future training programs. Through the repeated teaching cycles, their abilities as lecturers and expertise as teachers were improved. Based on the analysis results, suggestions for developing training lecturers' expertise and for educating lecturers were made. 이 연구의 목적은 통합사회 연수강사 양성 과정을 통해 연수강사로서 그리고 교사로서 어떤 성장이 있었는가를 밝히는 데 목적이 있다. 통합사회는 2015 개정 교육과정의 신설과목으로 이 연수는 통합사회를 가르쳐 본 교사가 없다는 데에서 출발하였다. 연수강사들은 다양한 전공 교원들로 구성되었고, 연수 프로그램을 개발하는 과정에서 강사역량 및 교사로서의 전문성을 키워갔다. 먼저 강사들은 좋은 수업을 실천하려는 동료들의 열정과 전문성으로부터 자극을 받았고 연수자료집 개발 과정에서 상호간에 신뢰, 지지, 존중의 관계성을 형성하였다. 이러한 심리적 안정감 속에서 전공이 다양한 교원들과 의사소통을 통해 자신의 관점을 확장하고, 낯선 것을 받아들일 수 있었다. 셋째, 통합사회 강사 워크숍에서 배운 지식과 방법 등을 연수에서 그리고 자신의 수업에서 적용할 수 있었다. 이러한 과정을 통해 워크숍에서 습득한 지식과 방법이 자신의 온전한 것으로 체화되고 있었다. 넷째, 강사 워크숍에서 배운 것을 실제의 연수와 교사의 삶에서 실천한 후, 이러한 성찰의 경험을 또다시 연수 프로그램 개선에 피드백 할 수 있었다. 이러한 선순환이 반복되면서 강사로서의 역량과 교사로서의 전문성이 축적되었다. 이상의 분석 결과를 토대로 교원연수에 있어 연수강사의 전문성 신장 및 강사 양성에 대해 시사점을 제안하였다.

The purpose of this study is to identify the ability of student in achievement levels. For this purpose, we analyzed the questions of social studies in National Assessment of Educational Achievement in 2004~2008. Specifically, in achievement levels we confirmed differences depending on the behavior area and examined differences depending on the characteristics of materials like degrees of complexity and familiarity. The results are as follows. First, there were no differences in behavior area in achievement levels. Second, we recognized differences according to the characteristics of materials in achievement levels. In familiarity of materials, high degree of familiarity is related to basic level. In the complexity of materials, basic level is related to simple materials, but in excellent level, there are many items that have materials of high degree of complexity. Implications are as follows: 1. The characteristics of questions should be analyzed more closely through specified analytical framework. 2. It is necessary to develop a variety of materials in National Assessment of Educational Achievement. 3. Items should be developed to response on hierarchical thinking. 4. In social studies class, we need to facilitate students to interpret meanings of materials that are complicated and unfamiliar.

This study investigated the influence of resilience and social support on pre-service early childhood teachers’ grit, and examined the mediation effect of social support in the relationship between resilience and grit of pre-service early childhood teachers. A survey was conducted with 297 pre-service early childhood education teachers attending university in Gyeongsang-do. The data were analyzed using Pearson correlation analysis, multiple regression analysis, and Sobel test. The results of the study are as follows. First, there were significant positive correlations among pre-service early childhood teachers’ resilience, social support, and grit. Second, resilience and social support had a significant direct effect on grit. Third, mediation analysis results suggested that pre-service early childhood teachers’ social support mediated the relationship between resilience and grit. The results in this research are that pre-service early childhood teachers’ social support and resilience should be considered to develop grit.

중,고등학생의 관용성 분석과 관용교육 개선에 관한 연구

There have been theoretical arguments for the approaches of tolerance education in social studies education fields, besides the argument that tolerance is an important virtue in a pluralistic society. It was fairly discussed that the insistence such as ``cognition-centered approach for tolerance education is needed`` or ``affection-oriented is required.`` But enough research has not been conducted to prove these arguments experientially. Also, such theoretical insistences are criticized that they categorize students into the same group without any consideration for various background variables. In this case, I suggest for intensifying the arguing level through two kinds of research questions and low rank hypothesis on current tolerance education. First, research question 1 is ``What influences tolerant cognition and tolerant affection will give to tolerant behaving tendency?`` Second, research question 2 is ``Will tolerant judgment and affection which affect tolerant behaving tendency be different according to age group?`` To certify research questions above, I surveyed 556 students in 2nd grade of middle and high school. In the result of research question 1, tolerant judgment and affection affects tolerant behaving tendency meaningfully. But the difference of level for tolerant knowledge comprehension doesn`t influence on tolerant behaving tendency. In the result of research question 2, it is proved that the effect of tolerant judgment and tolerant affection influencing tolerant behaving tendency differs by the age. In case of middle school students group, tolerant affection shows meaningful relations with tolerant behaving tendency except tolerant judgment. However, in case of high school students group, both tolerant judgment and affection appeared to be variable factors that explain tolerant behaving tendency.

This study was to find out whether organizational culture and job satisfaction affect psychological well-beings of teachers in early childhood settings. For this, data were collected from 291 early childhood teachers from early childhood settings in Gyeongsangman-do. With SPSS 18.0, Pearson correlation coefficient was used to investigate the relationship among organizational culture, job satisfactions, and psychological well-beings. Multiple regression analysis was applied to look for the effect of organizational culture and job satisfaction on psychological well-beings. As results, overall organizational culture had a significant relationship with teachers` psychological well-beings. Group culture and hierarchical culture had an effect on teachers` psychological well-beings. Also, there was a meaningful relationship between overall job satisfaction and teachers` feeling of well-beings. Lastly, the relationship with other colleagues and job itself influenced psychological well-beings of early childhood teachers.

The purpose of this study is to suggest that specific ways in affective domain education through analysing on 2007 revision curriculum. As a consequence of social studies curriculum analysis, there are affective words like sense of community, respect of human rights, tolerance etc. And In describing aims, it has a balance in knowledge, skills and attitude education. We can`t find contiunity and sequence in affective domain contents. In learning activites, it was recommanded case activities and experience activities. But they was differently used in primary schools and secondary schools. On evaluating, it is inclined to evaluate behavior or internalization in primary schools but it has a tendency in evaluating according to hierarchy of cognitive domain. I suggest, First, affective domain contents are extracted in relation I and others, I and society. Second it is different from contiunity and sequence in cognitive domain education. We build contiunity and sequence in affective domain education like from reciving to behaving according to Hauenstein. Third, we need to adopt perspectives of evaluation, assessment in affective domain education.
