임효진 ( Hyo Jin¸ Lim ),최은혜 ( Eun Hye¸ Choi ),박호익 ( Ho Ik¸ Park ),이지현 ( Ji Hyun¸ Lee ) 한국초등교육학회 2021 초등교육연구 Vol.34 No.3

본 연구에서는 초등교사가 가지고 있는 열정에 대한 인식구조를 파악하기 위해 현직 초등교사 131명을 대상으로 설문조사를 실시하였다, 연구에서는 열정, 열정의 장단점, 교사열정에 대한 인식구조를 알아보기 위해 의미연결망 분석을 활용하여 근접 중심성, 연결중심성, 매개중심성, 아이겐벡터 중심성을 위주로 살펴보았다. 연구결과 첫째, 열정에서는 ‘힘’,‘강렬’과 같은 높은 강도나 에너지를 나타내는 단어들이 중요한 역할을 하였으며 커뮤니티 분석 결과 열정의 행동, 정서, 동기 특성에 대한 주제가 분류되었다. 둘째, 열정의 장점에서는 ‘삶’,‘원동력’,‘에너지’등이, 열정의 단점에서는 ‘타인’,‘피로’,‘살피지 못함’등이 중요한 역할을 하는 것으로 보아 기존 이론에 나타난 열정의 특성을 설명하고 있었다. 셋째, 교사열정에서는 ‘학생’,‘수업’과 같은 교수활동의 실천을 나타내는 단어들이 중요한 역할을 하였으며 커뮤니티 분석 결과 교육활동 전반, 학생과 수업, 전문성 개발에 대한 주제가 분류되었다. The purpose of this study was to explore the meaning of passion perceived by elementary school teachers. In order to understand the structure of perception of passion, we surveyed 131 in-service elementary school teachers. Responses to passion, the positive and negative role of passion, and teacher passion were analyzed using a semantic network analysis. We focused on closeness centrality, degree centrality, betweenness centrality and eigenvector centrality. Results showed that first, in passion, words indicating high strength and energy such as‘power’and‘intensity’played an important role in the structure of perception. Themes on behavioral, emotional, and motivational characteristics of passion were classified as sub-factors of passion as a result of community analysis. Secondly,‘life’,‘motivation’, and‘energy’appeared in key-word analysis in the positive role of passion while‘others’,‘fatigue’, and‘not caring for’appeared in the negative role of passion, reflecting the theory on the dualistic model of harmonious and obsessive passion. Third, in teacher passion, words indicating teaching activities and their practices such as‘student’and‘instruction’played an important role in the structure of perception. Themes related to educational activities in general, students and instruction, and professional development were classified as sub-factors of teacher passion.

임은미,김현진 전주대학교 사회과학종합연구소 2002 社會科學論叢 Vol.18 No.-

본 연구는 인터넷을 활용한 진로정보탐색 프로그램이 대학생들의 진로자기효능감에 미치는 영향을 검증하기 위한 것이다. 이에 대학생을 대상으로 하는 인터넷을 활용한 진로정보탐색 프로그램을 제작하였다. 이 프로그램은 김봉환 등(2001)이 제안한 모듈식 진로상담 프로그램의 개념을 임은미와 장선숙(2002)이 중등학생을 위해 적용한 것을 대학생의 상황에 맞게 수정하여 제작되었다. 프로그램 회기는 4회기로 구성되어 있으며, 그 내용은 프로그램 분위기 조성 및 온라인 직업흥미검사 실시(60분), 직업흥미검사 결과의 해석과 직업세계의 이해(60분), 정보사냥대회(60분), 직업정보탐색과 마무리로 이루어져 있다. 프로그램의 실시 전후에 <진로의사결정 자기효능감 검사>를 실시하고, 사전-사후검사 점수 차이를 분석하여 프로그램의 효과를 검증하였다. J대학교의 1학년 남녀학생 가운데 자발적인 신청자들을 대상으로 본 프로그램을 적용한 후 실험집단과 통제집단의 사후검사 점수 차이를 비교한 결과 프로그램 참가자들은 통제집단에 비하여 사후검사에서 의미있게 높은 점수를 얻었다. 이러한 경향은 진로 의사결정 전체 Q뿐 아니라 문제해결 하위영역을 제외한 목표설정, 계획수립, 자기평가, 직업정보탐색의 전 하위 영역에서도 동일하게 나타났다. 이러한 결과는 대학생을 대상으로 인터넷을 활용하여 단기에 실시하는 진로정보탐색 프로그램이 대학생의 진로의사결정 효능감을 높여줄 수 있음을 시사한다. The purpose of this study is to examine the effects of career information exploration program using internet on the undergraduates' career decision-making self-efficacy. For this purpose, career information exploration program using internet was developed. The main factors of this program are performing the free on-line interest test, explorating the career information web-sites, and getting career information through internet according to the participants' interests. The results showed that the experimental group got higher score than the control group in CDMSES(Career Decision-Making Self-Efficacy Inventory). But for the problem solving subcategory, this tendency was shown in all the sub factors of CDMSES, i.e. goal-setting, career planning, collecting information, and self -evaluation. The implications about education or counseling programs for the undergrauates were discussed.

임정현,강경화,이종진,김은철,김상철 대한치과교정학회 2001 대한치과교정학회지 Vol.31 No.5

치아이동시 골세포간 활성 조화에서 세포간 교통의 중요성이 차츰 인식되고 있으며 세포간 교통을 위한 교통반의 존재가 확인되고 있다. 동물실험 모델에서 실험적 치아이동을 통해 조성된 압박 및 견인측 치주인대에서 교통반 단백의 일종인 connexin 43의 발현을 관찰함으로써 인접 연조직 및 골 조직 내에서 세포 신호 전달 양상의 한 부분을 파악하고자 하였다. Sprague-Dawley계 백서 27마리를 대조군(3마리)과 실험군(24마리)으로 나누었으며, 실험군은 견인력(75g)을 가한 후 12시간, 1일, 4일, 7일, 14일, 28일이 경과한 후 각각 4마리씩 희생시켜, connexin 43의 발현을 면역조직화학적으로 관찰한 바 다음과 같은 결과를 얻었다. 1.대조군에서의 connexin 43 발현은 치은, 상아질, 치주인대, 치수, 골세포에서 경미하였다. 2.교정적 치아이동에 반응하는 치수, 치주인대, 골모세포, 파골세포, 골세포부위에서 connexin 43의 발현이 많았으나 치은, 상아질, 상아모세포에서의 발현은 견인력 적용기간에 관계없이 대조군과 큰 차이가 없었다. 3.치수에서 connexin 43의 발현은 교정력을 가한 4일에서부터 증가하여 7일째까지 크게 증가한 후 14일째부터 감소되었으며 28일째에는 대조군과 차이가 없었다. 4.치주인대에서 connexin 43의 발현은 주로 혈관을 중심으로 치조골 면을 따라 압박측에서 주로 나타났는데 교정력을 가한 12시간에서부터 증가하여 4일에서 가장 많은 발현을 보인 후 7일부터 감소하기 시작하였다. 5.골모세포 및 골세포에서 발현은 실험 1일째부터 출현해 4일째에 가장 많은 발현을 보였고 7일 이후에는 크게 감소하였으며 파골세포에서의 발현은 골모세포와 골세포보다 실험 4일째에 더 많이 관찰할 수 있었다. Bone remodeling in response to force requires coordinated actions of osteoblasts, osteoclasts, osteocytes, and periodontal ligament cells. Coordination among these cells may be mediated, in part, by cell-to-cell communication via gap junctions. This study was designed to evaluate the expression of gap junction, connection 43 in periodontal tissue during the experimental movement of rat's incisors, by LSAB(labelled streptavidine biotin) immunohistochemical staining fort connexin 43. Twenty seven Sprague-Dawley rats were divided into a control group(3 rats), and 6 experimental groups(24 rats) where 75g of force was applied from helical springs across the maxillary incisors. Rats of experimental groups were sacrificed at 12 hours, 1, 4, 7, 14 and 28 days after force application, respectively. And the tissues of a control group and experimental groups were studied immunohistochemically. The results were as follows : 1.In control group, the expression of connexin 43 was rare in gingiva, dentin, cementum, periodontal ligament and bone cells. 2.In experimental group, the expression of connexin 43 was increased in pulp, periodontal ligament, osteoblasts, and osteoclasts, comparing to that in control. And it was rare in gingiva, dentin, and odontoblasts regardless of the duration of force application, which was not different from that of control group. 3.The expression of connexin 43 in pulp of experimental group began to increase in 4-day after force application and got to the highest degree at 7-day. And it decreased after 14-day to be similar to that of control group at 28-day. 4.The expression of connexin 43 in periodontal ligament was noted in small capillaries adjacent to alveolar bone, showing higher intensity of immunolabelling after 4-day. And it was stronger in the pressure side than in tension side of periodontal ligament. After 7-day, decrease in connexin 43 expression was observed. 5.The expression of connexin 43 in alveolar bone began to increase 1-day, reached to the highest degree at 4-day, and decreased at 7-day. And the expression in osteoclasts was more than that in osteoblasts or osteocyte at 7-day.

All-Trans Retinoic Acid에 의한 HL-60 세포 분화유도중 H2B Histone, c-Myc 및 DNA Topoisomerase I 발현에 관한 연구

임규,박정동,최병한,이용진,김계영,이명선,장은미,김삼용,권기량,곽상태,황병두 忠南大學校 癌共同硏究所 1998 癌共同硏究所 硏究誌 Vol.2 No.1

Effects of all-trans retinoic acid(retinoic acid) on DNA replication, H2B histone and DNA topoisopmerase I(Topo I) gene expression have been investigated in human promyelocytic leukemia cell line HL-60. DNA synthesis decreased at 24 hours after exposure of retinoic acid in the HL-60 cells. H2B histone mRNA rapidly reduced at 48 hours and Topo I and c-myc mRNA at 24 hours in retinoic acid-exposured HL-60 cells, respectively. The levels of c-myc, H2B histone and Topo I gene expression were reduced in proportion to the concentration of retinoic acid. The H2B histone mRNA in retinoic acid-exposured cells was elevated by cycloheximide treatment, while the level of Topo I mRNA was constant. These results suggest that regulations of H2B histone, c-myc and Topo I gene expression are different from one another, and repression of Topo I gene is closely correlated with c-myc gene during retinoic acid-induced differentiation of HL-60 cells.

임채성,최은아,박정인,이수진 부산교육대학교 과학교육연구소 2004 科學敎育硏究 Vol.29 No.-

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.

임난영,이은영,양용숙,정순애,차경옥,이여진 대한류마티스 건강전문학회 2000 근관절건강학회지 Vol.7 No.1

This study was designed to distinguish by the characteristic difference and the degree of symptoms such as fatigue, pain, coping to pain, and efficacy on pain, and to offer descriptive data for nursing intervention for improving coping ability to pain along each characteristics of disease in chronic arthritis and systemic lupus erythematosus. The subjects were 135 outpatients in the hospital for rheumatic disease in H-University, Seoul. The data were collected by structural questionnaire, from April 29 to June 29, 1999. The results were that the fatigue score was high in the OA patients while the RA patients and SLE patients experienced middle range of fatigue score, but which was not statistically different. Although the RA patients felt higher pain than other diseases, they have well coped with their pain than the others. In efficacy on pain the SLE patients had higher score than others but all of the disease showed lower score. No statistically significant difference among the three croup was recorded in efficacy on pain. Therefore, pain management in the RA patients was primary nursing intervention because they felt severe pain and have well coped with pain while they had lower pain efficacy score than the others. It is also important that fatigue management and coping strategies on pain for the OA patients and SLE patients are specially supportive in the nursing intervention.

Lim,Jung-Dae,Yang,Deok-Chun,Lee,Hyeon-Yong,Kim,Jong-Dai,Lee,Jin-Ha,Sung,Eun-Soo,Yu Chang-Yeon 한국자원식물학회 2004 Plant Resources Vol.7 No.1

The establishment of an efficient protocol for plant regeneration and micropropagation from leaf explant cultures of Chicory, Cichorium intybus L. var. sativus. is reported. Callus formation rate appeared 100% from explant in all growth regulators, but calli formed in the prensence of naphthaleneacetic acid (NAA) were appeared very compact and non-embryogenic state. The regenerated shoots were obtained from leaf explant cultures on solid MS medium containing different concentrations of cytokinins and auxin. The highest number of shoots (5.7) per explant and shoot growth (2.8cm) was obtained on MS medium containing 0.1 mg BAP L^-1 and 0.1 mg NAA L^-1. Indole acetic acid was the most suitable auxin for root formation among three auxins tested. 2,4-D had no effect on shoot and root formation.
