김재경,김용관,유준영,주진철,이창선,Kim, Jae-Gyung,Kim, Yong-Kwan,You, Jun-Young,Joo, Jin-Churl,Lee, Chang-Sun 대한악안면성형재건외과학회 1998 Maxillofacial Plastic Reconstructive Surgery Vol.20 No.2

구강악안면영역은 그 해부학적 구조상 혈관 분포가 풍부하고 따라서 구강내로 접근하는 수술시 신체 다른 부위와 달리 출혈 소견을 많이 보이며 수술중 과다출혈의 방지와 지혈의 목적으로 epinephirne soaked gauze즉 bosrnine gauze의 사용이 널리 이루어지고 있고 또한 사용이 불가피하다고 할 수 있다. 그러나 이 부분은 혈관 분포가 풍부하므로 epinephrine의 systemic uptake의 가능성 또한 존재한다 할 수 있겠다. 고농도의 epinephrine은 이론상 혈관수축을 일으켜 순간적인 systemic volume overload의 상태를 야기시켜 폐부종 및 pulmonary effusion을 일으킬 수 있으나 아직까지 보고된 바 없었다. 악안면부위는 혈관공급이 많아 수술중 지혈이 용이하지 못해 bleeding control을 위해 또 습관적으로 bosmine 거즈의 packing이 행해지고 있지만 수술자에 의한 정확한 농도로 희석된 bosmine 거즈 사용이 필수적이다. 본원에서 양악 악교정 수술시 소독간호사에 의해 잘못 희석된 고농도의 bosmine 거즈를 상악후방에 packing하여 발생된 전신적 합병증으로써 폐부종이 발생한 바 bosmine 거즈의 사용시 사용부위에 따라 농도의 확인과 술자의 주의를 요한다고 생각된다. There are many vessels in oral and maxillofacial region. Therefore blood oozing is a frequent findings in this area when operation takes place. Beacuse of this, most oral and maxillofacial surgeons as well as operators of this region usually use bosmine soaked gauze for oozing control during operation. Theoretically overdose of systemic epiniephrine(bosmine) may lead to pulmonary edema due to secondary systemic volume overload. For this reason, oral and maxillofacial surgeons should give more attention to the use of bosmine soaked gauze. In spite of this possibility, epinephrine induced pulmonary edema using bosmine soaked gauze has not been reported. We experienced one case of pulmonary edema which was induced by epinephrine overdose by bosmine soaked gauze that has not been diluted by mistake in preparing bosmine soaked gauze. The authuors report a case with review of literature.

While nontuberculous mycobacterium (NTM) infections are recently on the rise, arthritis caused by NTM is hardly reported in Korea. NTM arthritis has no distinctive clinical characteristics from chronic arthritis. Tuberculosis of the joint specifically produces similar clinical and pathologic presentations to NTM arthritis, so it is not easy to distinguish between them. We report a case of Mycobacterium intracellulare in an arthritis patient after trauma and surgical repair of the injury. At the beginning, the patient was diagnosed as tuberculous tenosynovitis through pathology without microbiologic evidence. The final diagnosis was made after subsequent recurrences for several years. The misdiagnosis and delayed diagnosis led to irreversible joint destruction and functional impairment. NTM infection must be included in the differential diagnosis of chronic arthritis at the outset.

Herein we report the case of a 71-year-old woman who complained of fatigue and enlarged right axillary lymph nodes for 18 months. At her first visit, her chest X-ray showed diffuse nodular opacities in both lung fields. Initial excisional biopsy of the axillary lymph nodes showed granulomatous lesions and acid fast bacilli were seen on Ziehl-Neelsen staining. However, even after 15 months of anti-tuberculosis (TB) medication, her right axillary lymph nodes were enlarged. We re-performed an excisional biopsy of the nodes, which showed Hodgkin`s lymphoma (HL). A retrograde review of the biopsy before anti-tuberculous medication, revealed HL coexisting with TB. HL and TB cause difficulties in differential diagnosis due to similarities in clinical course, imaging procedures and histopathological analysis of the involved tissue. Therefore, it is important to consider the possibility of concurrent HL and TB when patients who undergo treatment for TB or chemotherapy for lymphoma complain of persistent systemic symptoms or enlarged lymph nodes.

Hepatocellular calcinoma (HCC) is the fifth most common cancer and the third leading cause of cancer-related deaths worldwide. It is important to diagnose HCC exactly before management is attempted. But, the clinical presentations and radiologic findings of liver abscess, HCC, and metastatic tumor to the liver may be quite similar, and procedures such as serum tumor marker assay, computerized tomography, and ultrasonography of the liver cannot make a specific diagnosis. We report a case of HCC successfully diagnosed by surgery which was misconceived as liver abscess and not improved by medical treatment. (Korean J Gastroenterol 2009;53:378-382)

웹 기반 중학 과학 교육 연구

김재경,김정환 대구대학교 기초과학연구소 2003 基礎科學硏究 Vol.19 No.3

This study attempts to investigate the learning effect of the Web Based Instruction(WBI), which our lab developed for middle school science, through surveying attitude to WBI, and accomplishment test conducted on students after being practiced WBI lesson. Accomplishment test reveals that WBI group(73.5) scores 6 points over traditional instruction group(67.5). This result suggests that WBI is more effective on learning than traditional instruction. For the accomplishment score lower than 50 point, the number of students who belong to WBI group is much smaller than that of traditional group. But WBI group's number is twice as much as traditional group's for the score higher than 90 point. This results suggest that WBI is effective both superior and inferior group. Thus, it is desirable to apply WBI positively on school education taking another benefit into consideration, thai WBI meed the incarnation of constructivism, such as enhancement of self-initiative learning ability, sense of responsibility, and diverse personal interactions including collaboration.

Polaron들 간의 有效 相互作用

金在慶 韓社大學 1980 대학논문집 Vol.10 No.-

The effective interaction between polarons in polar crystals is explored based on the electron-phonon interactions. Our study reveals that the energy of two polarons in interaction with lattice vibrations in not additive, but an additional interaction energy arises which depends on the distance between the polarons. This energy is seen to be negative, I. e. as a result of interaction with the lattice vibrations an attractive force is produced between particles with charges of the same sign. It would be a repelling force oppositely charged particles.

金在慶,金相淵,姜信珪 嶺南大學校附設 基礎科學硏究所 1985 基礎科學硏究 Vol.5 No.-

Intermetallic compound of ?? with B8₂ type structure has been studied in the range 40˚-393˚K using the Mossbauer effect. Spectrum shows the complicated reson ance lines corresponding to the two magnetically inequivalent Fe site. At 40˚K the following hyperfine structure parameter have been obtained H.S(2(a) site)=210KOe. H.S(2(d)site)=140KOe. I.S(2(a) site)=0.208mm/sec. I.S(2(d) site)=0.170mm/sec. It show that the ?? occupied in 2(a) site and ?? in 2(d) site and the magnetic moment of Fe in 2(a) site is larger than the 2(d) site.

Lead Borate 유리內에서의 Fe ion의 Mossbauer 效果硏究

姜信珪,金在慶 嶺南大學校附設 基礎科學硏究所 1984 基礎科學硏究 Vol.4 No.-

A Mossbauer spectroscopic study has been mad on χFe₂O₃ㆍ1-χ(PbOㆍ3B₂O₃), where 10≤χ≤50mole%. The characteristic feature of all the spectra is the appearance of three peaks, due to two pairs of peaks of gradrupole doublet of ?? and ??. The mean values of isomer shift and guadrupole splitting for the ferric cations are 0.19mm/sec and 1.10mm/sec, and for ferrous cations 0.77mm/sec and 2.70mm/sec. The isomer shift and quadrupole splitting of the ferrous and ferric peaks in the Mossbauer spectra are almost independent of the Fe₂O₃content. The line width of the quadrupole split peaks of ?? increases with decreasing iron content of the glass, and that of the ?? increases too in the same manner. The ratio of ferrous to ferric cations increases with decreasing the content of Fe₂O₃. The possible explanation for all the features mentioned above are presented.

과학수업에서 NIE를 활용한 학습자료 개발 연구

김민수,김재경 대구대학교 사범대학 부설 교육연구소 2008 敎育硏究 Vol.3 No.2

We developed teaching materials of NIE(Newspaper In Education) and lecture model of NIE which are usable in the class of high school physicsⅡ, at the part of atomic nucleus. The NIE teaching materials were developed with the articles which were searched from 8 daily newspapers issued from 2003 to 2007, on the basis of essential constitutional elements of STS curriculum, proposed by Yager. NEBCP, the lecture model of NIE, utilizes these developed NIE teaching materials, and divides into 5 steps, newspaper(N), exploration(E), buzz discussion(B), choice(C) and practice(P). We examined the educational effect and the degree of preference after applying these teaching materials and lecture model to high school 3rd grade. The developed NEBCP lecture model based on NIE proved to be worthwhile, challenging and fruitful at science class. At the course of NEBCP, the students showed more interest than the traditional methods. And they wanted to study physics more often with NEBCP. Thus NEBCP will increase students’ interest, confidence and will make students more initiative at science class. 고등학교 물리II의 원자핵 단원에서 활용할 수 있는 신문활용교육(NIE)의 학습자료와 수업모델을 개발하였다. NIE 학습자료는 Yager가 제시한 STS 교육과정의 필수 구성요소를 기준으로, 2003년에서 2007년 사이에 발간 된 8개 일간지의 기사들로부터 검색 하여 제작되었고, 이들 학습자료를 활용하는 NEBCP 수업모형은 신문, 탐구, 버즈토의, 선택, 실천 등의 5단계로 나누어진다. 개발한 원자핵 단원의 NIE 학습자료와 NEBCP 수업모형을 고등학교 3학년을 대상으로 적용한 후 NIE 학습자료와, NEBCP 수업모형에 대한 학습효과와 신문활용교육의 선호도를 설문으로 조사하였다. 개발된 신문활용교육을 기반으로 한 NEBCP 수업모형은 과학과 수업에서 가치있고, 도전적이며 풍성한 성과를 거둘 수 있었다. 학생들은 전통방식에 비해 NEBCP의 수업과정에서 학습중 더 많은 흥미를 보였고 더 자주 NEBCP를 통하여 물리를 배우기를 원한다고 하였다. 따라서 NIE 및 NEBCP는 학생들의 흥미도와 자신감을 높이고, 과학 수업에서 더욱 적극적인 참여를 유발한다고 보여진다.
