김원기,전만중,박상호 한국체육사학회 2003 체육사학회지 Vol.12 No.-
This paper started from a necessity to reconsider boxing sports, the only sports game that brought about our patriotism during the time when most of us were poor, and flied away out stress and anger, also, that made us dream and have a hope. The boxing game attracted people's interest at that time, meeting the spirit of hungry. However, boxing sports became an unpopular game nobody pays attention to. The reason was that all boxing games mobilized many boxing players and enthusiastic audience in the past, but as GNP elevated greatly, there are few hungry persons, the spirit of hungry was subdued, the number of players drastically decreased, demand of audience reduced, people don't enjoy watching boxing games, there are few spectators in boxing gyms, no sponsors support relay broadcasting for boxing games. Furthermore, results have been very poor in various amateur international boxing match, all broadcasting stations became to dislike relay broadcasting of international matches. A certain broadcasting station regularly sent out pro-boxing game programs every weekend for 45 years as it took a full charge of pro-boxing game, but frequency of relay broadcasting reduced now, and the reason that the popularity rating is lower than other popular sports games made the station avoid relay broadcasting, These results mean that reducing number of TV relay broadcasting showing the highest PR effect made boxing games inactive. Summing up the study, the reasons that boxing games have declined popular sports games' appearing, high-leveled foreign players' watching TV games, the law of diminishing marginal utility, and democratized society. As a result, demand of boxing games rapidly reduced. However, boxing games in Korea must remember Kim, Ki-su's acquisition of championship on July the 25th, 1966, WBA championships obtained by 16 players including Hong, Su-wan, Yu, Myung-woo, Park, Jong-pal, Mun, Seong-kil, and 11 WBC championships acquired by Yeon, Dong-kyun, Jang, Jeong-gu. They surely won an international fame flying the taegeuk flag all over the world. Also, in spite of short history of woman pro-boxing, Lee, In-young acquired a world championship, therefore, Korea still has a hope to meet another new jumping moment.

고유함수전개법을 이용한 비대칭 유전체 원주공진기의 공진특성해석
류원열,민경호,장중호,전오곤,이창화,최현철 경북대학교 센서기술연구소 1998 센서技術學術大會論文集 Vol.9 No.1
The resonant frequency of the dielectric rod resonator which is surrounded by cylindrical cavity can be calculated very exactly by using eigenfunction expansion method in the concept of electric and magnetic wall from the symmetry. But if the supporter is put in the cavity, the symmetry disappears. Thus this method has some errors. In this paper, the resonant frequency of the asymmetric dielectric rod resonator was calculated by using the eigenfunction expansion method. Also, the effect of the supporter was discussed. Then we found that the resonant frequency was more affected in the case of TM mode than TE or Hybrid modes as the length of the supporter was longer.

양막상피세포와 영양배엽세포에서 α1-antitrypsin 의 발현에 시토카인이 미치는 영향
이희섭,전병훈,김정중,김원신 원광대학교 생명공학연구소 1995 생명공학연구소보 Vol.3 No.1
We have examined indirectly the expression of α1-antitrypsin by determined the TIC(trypsin inhibitory capacity) in the cultured medium of the amnionic ephithelial cell and trophoblasts. The TIC of the cells was cultured in the presence of supernatent by treatment of neutrophils with(CNMP) or without(CNM) phorbol myristate acetate(PMA) is identical in both coultured cells. By the western blotting analysis, the substance possess the TIC in the cultured medium is identified to the α1-antitrypsin. From these results, the cytokines secreted by the neutrophils did not affected the secretion of α1-antitrypsin in the both cultured cells. But, some unidentified proteinases cleaved the α1-antitrypsin. Thus the neutrophil proteinases might be involved in premature rupture of the membranes(PROM) by any means.

초등학교 6학년 학생이 지각한 자아존중감, 학습전략, 학교적응, 자기주도학습 간의 구조적 관계
전중원 ( Jeon¸ Joong Won ) 한국초등교육학회 2021 초등교육연구 Vol.34 No.3
본 연구는 초등학교 6학년 학생의 자아존중감과 자기주도학습의 관계에서 학습전략과 학교적응의 구조적 관계를 검증하고자 하였다. 이를 위해 부산광역시 교육정책연구소의 종단연구 3차년도 패널 자료를 이용하였다. 본 패널 자료는 2018학년도 7월부터 부산광역시 교육청 산하 5개 교육 지원청의 67개 초등학교 6학년 대상으로 이루어 졌으며, 총 2,845명의 자료를 수집하였다. 이중 결측치가 포함된 160명의 자료를 제외한 2,685명의 설문 결과를 최종 연구 결과 분석에 사용하였다. 연구 모형 분석을 위해 구조방정식 모델링을 적용하였고, 매개효과 분석을 위해 Bootstrapping-test를 실시하였다. 연구의 결과는 다음과 같다. 첫째, 자아존중감, 학습전략, 학교적응, 자기주도학습은 모두 정적인 관계를 가지는 것으로 나타났다. 둘째, 자아존중감과 자기주도학습의 관계에서 학습전략과 학교적응은 매개효과를 가지는 것으로 나타났다. 이러한 결과를 토대로 초등학교 6학년 학생의 자기주도학습 향상에 자아존중감, 학습전략과 학교적응을 강조하고, 이에 따른 교육적 시사점을 논의하였다. The purpose of this study was to examine the mediating effects of learning strategy, school adaptation between the self-esteem and self-directed learning among the 6th grade students in elementary school. For this research, the study used a questionnaire survey from Panel Study on Busan Education longitudinal study targeting 2,685 elementary school students from the city of Busan. By means of the two step approach using the structural equation SPSS 21.0 and Amos 20.0, a confirmatory factor analysis was used to determine whether the measurement variables adequately identified the potential variables and the suitability and significance of the path throughout the subsequent study model. The findings derived from the analyzed data are as follows: Firstly, the relationship among self-esteem, learning strategy and school adaptation, self-directed learning showed significant variables. Second, if the self esteem had a direct impact on self-directed learning, then learning strategy and school adaptation as the mediators were influenced. As a result, this study showed that it is vital for the 6<sup>th</sup> grade students in elementary school to develop their self-esteem in order for self-directed learning to occur. A good learning strategy and school adaptation are also important. Based on this, the limitations and suggestions for further research were presented.

유기주석화합물에 단기간 노출시킨 넙치 간장 약물대사효소의 in vivo 및 in vitro 반응
전중균 ( Joong Kyun Jeon ),이지선 ( Ji Seon Lee ),전미정 ( Mi Jeong Jeon ),심원준 ( Won Joon Shim ),임한규 ( Han Kyu Lim ) 한국환경생물학회 2004 환경생물 : 환경생물학회지 Vol.22 No.1
유기주석화합물인 tributyltin chloride (TBTC)와 tributyltin chloride (TPTC)를 넙치 간장으로 만든 미크로좀에 in vitro적으로 노출시켜서 이들 화합물의 대사에 관여하는 mixed function oxidase (MFO) 중 cytochrome P450 (CYP) 농도와 7-etho-xyresorufin deethylase (EROD) 활성의 변화를 조사하였으며, 또한 in vitro 실험에서는 TPTC를 넙치에게 복강주사(7.5 mg kg^(-1) BW)하여 간장의 MFO (CYP농도, NADPH cytochrome c 환원효소 활성, NADH cytochrome b5 환원 효소 활성, EROD 활성) 반응을 경시적으로 조사하였다. 그 결과, in vitro에서는 TBTC, TBTO및 TPTC가 모두 CYP 농도와 EROD 활성을 저해하였으며, 저해력은 TPTC가 가장 컸고 이어서 TBTO, TBTC의 순이었다. 유기주석화합물의 노출농도와 노출시간과 비례하면서 저해 정도가 커졌으며, 특히 EROD활성의 저해는 노출농도에 크게 의존적이었다. 그리고 in vivo 실험에서도 유기주석화합물은 CYP농도, NADPH cytochrome c환원효소 활성, NADH cytochrome b5 환원효소 활성, EROD 활성을 억제하였다. EROD활성은 오염물질에 의한 반응이 민감하고 재현성도 있어 바람직한 측정지표로 이용될 수가 있을 것이다. Cytochrome P450 (CYP) contents and 7-ethoxyresorufin-O-deethylase (EROD) activity were determined in hepatic microsome of olive flounder (Paralichthys olivaceus) exposed to tributyltin chloride (TBTC), tributyltin oxide (TBTO), and triphenyltin chloride (TPTC). In addition, effects of in vivo (intraperitoneal injection of 7.5 mg kg^(-1) BW) exposure of flounder to TPTC on CYP, NADPH cytochrome c reductase, NADH cytochrome b5 reductase and EROD levels were measured. In in vitro exposure of hepatic microsome to organotins, TBTC, TBTO and TPTC reduced CYP contents and inhibited EROD activity. The TPTC was the strongest inhibitor, which is followed by TBTO and TBTC. The degree of inhibition, especially EROD acitivity, depended on the exposure duration. In addition, all the target enzymes in flounder were inhibited by TPTC with the in vivo exposure to TPTC. As EROD activity was the most sensitive to the inhibitions and demonstrated good reproducibility of the results, it could be used as a helpful tool for monitor effects of organotin compounds on mixed funciton oxygenase system in marine fish.

Small cell carcinoma is usually seen in the lung, but rarely involves the gastrointestinal tract including biliary tract. A 65 year-old man was admitted because of obstructive jaundice. A smooth-surfaced round intraluminal mass with proximal bile duct dilatation was seen in the proximal common bile duct on endoscopic retrograde cholangiogram. Under the diagnosis of bile duct cancer, pylorus-preserving pancreatoduodenectomy was done. Pathology revealed a 2 ㎝ sized small cell carcinoma in the proximal common bile duct and distal common hepatic duct. On immunohistochemical stain, the tumor cells were positive for neuroendocrine markers CD56 and synaptophysin. After surgery, the patient received 5 cycles of adjuvant chemotherapy with VIP (etoposide, ifosfamide, and cisplatin) regimen. However, the patient died of liver metastasis 12 months after the diagnosis. We report a case of extrapulmonary small cell carcinoma arising from the common bile duct.

본 연구는 Higgins, Friedman, Harlow, Idson, Ayduk과 Taylor(2001)가 개발한 조절초점 검사도구(Regulatory Focus Scale; RFS)를 한국판 초등학생용 조절초점 검사도구로 타당화 하기 위하여 수행되었다. 부산 및 경남 지역에 소재하는 초등학교 5, 6학년 재학생 750명을 대상으로 온라인 설문을 하여 665명의 유의미한 자료를 수집하였다. 주요 연구 결과는 다음과 같다. 첫째, 전문가 참여를 통해 감수 및 문항을 번역하였으며, 초등학생을 대상으로 예비조사를 통해 내용 타당도를 확보하였다. 둘째, 탐색적 요인분석을 실시한 결과, 한국판 초등학생용 조절초점 검사는 향상초점과 예방초점으로 구성되는 것을 확인하였다. 셋째, 확인적 요인분석을 실시한 결과, 조절초점 척도의 모형 적합도 지수는 적절한 수준인 것으로 나타나 본 척도의 구성 타당도를 확인하였다. 넷째, 조절초점과 성취동기, 행동활성화 간의 상관을 살펴본 결과, 조절초점은 성취동기, 행동활성화와 유의미한 정적·부적 상관을 보였다. 이를 바탕으로 본 척도의 수렴 및 변별 타당도를 확인하였다. 다섯째, 검사 및 재검사를 통해 타당화된 조절초점 척도의 검사-재검사 신뢰도는 양호한 수준임을 확인하였다. 본 연구는 한국판 초등학생용 조절초점 검사 도구가 학업 및 진로에 관한 조절전략을 파악하는데 기여할 수 있음을 보여주었다. 향후 동기 조절 전략을 다르게 사용하는 초등학생의 특성을 연구하는데 기초 자료로 활용될 수 있을 것으로 기대된다. The purpose of this study is to validate and verify the Regulatory Focus Scale (RFS) developed by Higgins, Friedman, Harlow, Idson, Ayduk, and Taylor(2001) for Korean elementary school students. The final data were collected by using online questionnaires targeting 665 elementary school students in the Busan and Gyeongnam area. The results of the study are as follows. First, question items were examined and translated by professionals. Then, the content validity were verified through a pilot test among elementary students. Second, by the means of exploratory factor analysis, it was confirmed that the RFS consisted of promotion and prevention focus. Third, as a result of confirmatory factor analysis, the model fit index of the RFS was shown to be at an appropriate level, therefore it was possible to reaffirm the construct validity of scale. Fourth, the RF was found to have a significant positive and negative correlations with the two concepts in examining the correlation among the RF, AM and BAS. Based on this, the convergent and discriminant validity related to the criteria of these scales were confirmed. Finally, after executing test-retest, it was confirmed that the internal consistency of RFS was good. The present study demonstrated that the Korean version of the RFS contributed to understanding the regulatory strategies in academic and career path. It is expected that this study will be used as basic data to study the characteristics of elementary school students who utilize motivation regulation strategies differently.
