In this research we took a lesson of the biology outdoor inquiry with preservice elementary teachers and investigated the science and biology teaching efficacy belief of theirs and analyzed it comparing with pre and post-lesson efficacy beliefs, their detailed major in university, their departments in high school, taking a course of applied biology Ⅱ in high school. The following results were obtained. First, preservice elementary teachers' science and biology teaching efficacy belief was changed positively after the lesson of the biology outdoor inquiry. Second, preservice elementary teachers' detailed major in university wasn't related with their science teaching efficacy belief of pre and post-lesson significantly in statistics, but related with their biology teaching efficacy belief of post-lesson significantly in statistics. Third, preservice elementary teachers' departments of high school wasn't related with their science and biology teaching efficacy belief. Fourth, taking a course of applied biology Ⅱ in high school wasn't related with science teaching efficacy belief, but related with biology teaching efficacy belief of pre-lesson significantly in statistics. However, That wasn't related with biology one of post-lesson significantly in statistics. That is, who haven't taken a course of applied biology Ⅱ in high school had not biology teaching efficacy belief before the lesson of the biology outdoor inquiry, but acquired much biology teaching efficacy belief after the lesson.

The Purpose of this is to analyze the aesthetics characteristics of our modern sports fashion, and thereby, discuss them in the light of the overall mentality or the 20th century, and thus, present the conditions or sports fashion design meeting modern people's divers aesthetics values and desired. Modern sports fashion styles can be categorized into futurist sports style, erotic sports style and American street sports style. And the 20th century mentality characterized by changes of lifestyle, identity and aspiration has influenced the aesthetic features of such sports fashion styles, which can be summed up as follows; First, the futurist sports style applies the functional items and details of active sportswear to design, while heralding a positive and hopeful message of technology and future by using the material of hi-tech functions and senses. This sports style was affected much by shift from social status, attraction and wealth to demonstration of state-of-the-art science, pursuit of functionality in terms of shapes and materials, convenience through free combinations of sportswear items of design elements. Second, the erotic sports style based on minimalism attempted to express the erotic body beauty indirectly by exposing some parts of body or using the material pressed against the body, This sports style was colsely related with the changes of sexual identity such as neutral sexualism, bi-sexualism and homo-sexualism. Lostly, the American street sports style was born from black Americans' sports and dances. This spors style pursues "youth" beyond TPO concept. As mass media and commercial sports developed, the young generation copied sports stars' uniforms or fashions to share honor, wealth and youth with them. In sort, the American street sports style was affected much by the so-called "heroism". Such a changed object of aspiration influenced the aesthetic characteristics of American street sports style directly.

In this study, the frequencies and types of questions about LIFE areas of the Science Curriculum of elementary school students were investigated through in-depth interviews with twelve 4th and 5th graders. The results of the research can be summarized as follows: (1) In conjectural question, the proportions of 'object exploration question' and 'object verification question' were high in all of the 4th graders and the students of low achievement level. (2) The numbers of causal questions generated by the 4th graders were much higher than those of the 5th graders. (3) The frequencies of the predictive, methodological, applicative questions were very low both in 4th and 5th grade students. (4) The numbers of conjectural questions were more in all students except the low achievement level of 4th graders at not-yet-taken contents than at already-taken ones. (5) The numbers of causal questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (6) The numbers of the predictive, methodological, applicative questions of the 4th graders were more at not-yet-taken contents than at already-taken ones, whereas opposite trend in the 5th graders. (7) The numbers of students' curriculum-related questions were more in all students except the low and middle achievement levels of 4th graders at not-yet-taken contents than at already-taken ones. (8) As ways for solving or seeking answers about questions, the 4th graders suggested methods of consulting experts or teachers (23.9%), internet searching (21.6%), and books or science-related encyclopedia (20.3%), while the 5th graders suggested the internet searching (36.5%), consulting experts or teachers (24.8%), and books or science-related encyclopedia (17.7%). Based an these results, we suggest several ways for improving the question-posing abilities of the students and adequate use of students' questions in the process of science teaching learning.

玉局齋 李運永의 가사문학 연구 : 유희적 성격을 중심으로

임채은 문창어문학회 2015 문창어문논집 Vol.52 No.-

There are two subjects to be examined through this study. One is the playfulness of six of Lee Woon-yeong’s gasa works in different styles, and the other is the meaning of his gasas in the history of gasa literature. Chapter II reviewed the background of Okgukjae’s gasa creation from the individual and social aspects. Section II-1 examined the background of his gasa creation from a biographical viewpoint through Lee Woon-yeong’s life and his peer relations. Section II-2 explored the characteristics of gasas created by 18th- century literati, and discussed the pattern of literary creation among 18th- century literati. Chapter III analyzed cases of gasa creation based on the forms of Yiseon music, dance songs, and lullabies from the aspect of intensifying the playfulness of Okgukjae’s gasas through borrowing other genres. From the results was found that Lee created gasas by adopting songs performed in feasts such as Yiseon music or common people’s genres such as dance songs and lullabies as a means to intensify playfulness. Chapter IV examined Okgukjae’s gasa works created through making up a fictional speaker, presenting a humorous conversation, or setting a judicial situation in the aspect of intensifying playfulness through theatrical situations. From the results was found that Lee intensified the playfulness of gasas by creating them with setting a theatrical situation as a device for stimulating the readers’ interest and amusing them. Chapter V, which is the conclusion, mentioned that Lee Woon-yeong, influenced by his father and brothers, pursued a life of freedom, associating with relatives and enjoying the scenery of landscapes, poetry, and go play rather than committing himself to politics or study. Gasa was a genre suitable for Lee Woon-yeong to express such a life attitude and interest in his surroundings and to lead a tasteful life. Thus, Lee Woon-yeong, although from a rich noble family in Seoul, created highly playful gasa works unlike most of other rich noble men in Seoul who seldom created gasas. Future studies may need to make more in-depth research on the nature of Okgukjae’s gasas and their position in the history of poetry.

In this study, we developed a evaluation system for performance assessment on applying science knowledge. It was based on theoretical background that we had studied previously. According to previous study, applying scientific knowledge is considered as science problem solving. So, we also developed a elementary science performance assessment tool based on science problem solving processes. the tool consist of a task, a response format and a scoring system, as other performance assessments with high quality the scoring system developed to assess students' responses contained in the response formats showed significant degrees of agreement among a science education expert, a in-service teacher an pre-service teachers. Therefore, by using the scoring system which based on assessment criteria, the whole processes of student learning could be assessed objectively.

김은지,전재은,임현주,차성철,정의룡,조용근,조용근 경북대학교 병원 1998 경북대학교병원의학연구소논문집 Vol.2 No.1

연구배경: 역학적연구에서 어류의 섭취가 많은 집단에서 관상동맥질환의 빈도가 낮은 것이 보고되었고, 이것은 어류에 많이 함유된 불포화지방산(polyunsaturated fatty acid) 특히 eicosapentaenoic acid 때문으로 생각되어지고 있다. 본 연구에서는 동맥경화증 발생의 초기단계로 여겨지는 단핵구와 혈관내피세포 사이의 adhesion에 미치는 다불포화지방산의 영향을 in vitro system에서 관찰하고자 하였다. 방 법: 제대정맥에서 얻은 혈관내피세포를 배양하여 96 well에 옮기고 25, 50, 100, 200 ㎛ 농도의 eicosapentaenoic acid(EPA)를 6시간 동안 처리한 U937세포를 부착시켜 adhesion assay를 시행하였다. 혈관내피세포를 자극하기 위해서는 lipopolysaccharide(LPS)를 well당 100 ng씩을 투여하였다. 음성대조군으로는 LPS로 자극하지 않은 혈관내피세포에 EPA처리를 하지 않은 U937세포로 adhesion assay한 성적을 사용했고, 양성대조군으로는 LPS로 자극한 혈관내피세포에 EPA처리를 하지 않은 U937세포로 adhesion assay한 성적을 사용했다. 그리고 EPA(3.3 mM)을 5㎛ CuSO4 및 300 ㎛ asscorbic acid와 혼합하여 섭씨 37도에서 16시간 두어 산화-EPA를 만들어 같은 실험을 반복하였다. 결 과: U937세포에 25, 50, 100, 200 ㎛의 EPA로 6시간 처리하였을 때 U937세포의 생존율은 99% 이상이었다. 혈관내피세포를 LPS로 자극했을 때 adhesion assay에서 혈관내피세포에 붙는 U937세포의 수는 현저히 증가하였다. 그러나 EPA를 U937세포에 25, 50, 100, 200 ㎛의 농도로 6시간 처리 후에 lipopolysac-charide를 처리한 제대정맥 내피세포에 부착(adhesion)시켰을 때 처리한 EPA의 각 농도에 따른 부착된 U937세포의 수는 통계적으로 유의한 차이를 나타내지 못했다. EPA처리가 부착된 U937세포의 수에 영향을 미치지 못하였다. 결 론: EPA는 U937세포에 영향을 미쳐 혈관내피세포-U937 세포부착을 감소시키지는 못하였다. 따라서 EPA에 의한 혈관내피세포-단핵구 부착 억제 효과는 EPA의 단핵구에 미치는 영향에 의하지는 않는 것으로 생각되나 추후 더 많은 연구가 필요하리라 생각된다. Background : Epidemiological studies have shown correlation between low incidence of coronary heart disease and high consumption of fish products. It has been suggested that this may be due to the high content of polyunsaturated fatty acids of the n-3 fatty acid group in fish oil. In animal studies eicosapentaenoic and (EPA) inhibited attachment of monocytes to the arterial endothlium. Method : Adhesion assay was performed on the endothelial cells of the human umbilical vein with 25, 50, 100, 200 ㎛ EPA-treated U937 cells. The endothelial cells were activated with lipopoysaccharide (LPS). The adhesion assay was repeated with oxidized EPA. EPA was oxidized with CuSO4 and ascorbic acid. Result : Viability of U937 cells were not afected by concentrations up to 200 ㎛ of EPAand oxidized EPA. LPS treatment of endothelium notably increased the number of U937 cells attached to endothelial cells on the adhesion assay. However, treatment of EPA, native or oxidized, to U937 cells did not afect the number of U937 cells attached to LPS activated endothelial cells. Conclusion : EPA treatment, native or oxidized, of U937 cells did not affect U937 cell-endothlial cell adhesion. This suggests that inhibition of monocyte-endothlial cells ◎attachment by EPA is not due to the effects of EPS on monocytes.(Korean Circulatin J 1998;28(4):606-610)

김은진,임채성 부산교육대학교 과학교육연구소 2002 科學敎育硏究 Vol.27 No.-

The purpose of this study was to investigate about current status of science field study in elementary schools. A total of 72 elementary teachers in Busan and Gyungnam districts was involved and the data from questionnaire was gathered. The questionnaire was comprised two parts: items on general level include the epistemological aspect and actual condition and items on concrete level according to chapters of elementary school science curriculum The major findings are as follows : 1. Many teachers cognize the requirement of science field study in 7th Korean elementary school science curriculum is larger than 6th one. But they respond the actual number of science field study in 7th curriculum is nearly equal to 6th. 2. In analysis to grades, the actual number of field study decrease as grade in high. 3. In the science content aspects, the requirement of field study is the largest on biology domain and earth science domain. 4. Many teachers have pointed out "the difficulty of administration for field study" and "unappropriated surrounding of their school" as the problems of science field study in elementary school.
