시각장애학교 시각장애교사의 여가활동 인식 및 실태 연구

이신영,이해균 한국시각장애교육&재활학회 2015 시각장애연구 Vol.31 No.2

The purpose of the study is to provide ground information to boost leisure activities available to the teachers with visual impairments. Teachers with visual impairments working in the schools for the visual impairments were asked to fill up a questionnaire concerning their current engagement in leisure activities. Followings are the summarized results from the survey. First, male teachers with visual impairments mainly answered that they do leisure activities either “to relieve physical and psychological tensions from work” or “to gain a variety of unusual experiences,” while the biggest number of female teachers said they do leisure activities “to relieve physical and psychological tensions from work.” On the other hand, when they were asked about the main causes that discourage them from challenge leisure activities, many teachers in their 20s said they can’t really afford any leisure activity, while those in the age of 30s or 40s, or those with total blindness or the unmarried all identically focused on saying “it’s not easy to find places or facilities accessible to those with visual impairments.” At the same time, many teachers over 50 answered they are “too busy doing work to try any leisure activity,” and those with low vision mainly said they “can’t spare time for leisure activity after doing house chores,” and married teachers with visual impairments also chose “too busy doing work to try any leisure activity.” Second, when they were asked about what they mostly do in spare time at school, married teachers usually said they study over teaching material, while unmarried teachers mainly said they do something on the computer. when they were asked about usual expenditures for spare time activities, both male and female married teachers samely checked “eating out with others”, and unmarried teachers picked “drinking alcoholic beverages with others.” There are also suggestions for further studies based on the research results. 이 연구는 시각장애교사들의 여가활동을 활성화하기 위한 기초자료를 제공하기 위해 전국 시각장애학교에 재직 중인 시각장애교사를 대상으로 여가활동 인식 및 실태를 설문조사하였다. 이에 대한 연구결과를 토대로 요약하면 다음과 같다. 첫째, 여가활용에 대한 인식은 남자교사가 ‘일에서 오는 심신의 피로를 풀기 위한 시간으로’와 ‘폭넓은 경험을 얻기 위한 시간으로’, 여자교사는 ‘일에서 오는 심신의 피로를 풀기 위한 시간으로’가 가장 높게 나타났다. 여가활용의 어려운 점으로는 20대교사는 ‘여가활동을 할 만한 경제적 여유가 없다’가, 30대와 40대교사, 맹교사와 미혼교사는 ‘시설 및 장소가 부족하다’가, 50대 이상교사는 ‘업무로 인해 여가시간을 내기 어렵다’가 가장 높았으며, 저시력교사는 ‘가사로 인해 여가시간을 내기 어렵다’가, 기혼교사는 ‘업무로 인해 여가시간을 내기 어렵다’가 가장 높게 나타났다. 둘째, 학교에서의 여가활용의 실태는 기혼교사가 ‘교재연구를 한다’, 미혼교사가 ‘컴퓨터를 한다’가 가장 높았고, 시설 확충에는 선천성과 후천성 모두 ‘휴게실’이 가장 높게 나타났다. 여가활동 비용은 남녀교사 모두와 기혼교사는 ‘외식비’가, 미혼교사는 ‘음주비’가 가장 높게 나타났다. 이러한 연구결과를 바탕으로 후속연구에 대해 제언하였다.

이신영 한국생물교육학회 2019 생물교육 Vol.47 No.2

This study aimed to explore differencesbetween successful and unsuccessful problem-solvers’ representationalcompetence revealed by the solving of twogenetic problems in different presentational modes. Fourhigh school students participated in solving two geneticproblems that contained diverse genetic concepts and requiredcomplex reasoning. Representational competence wasanalyzed with the form of representation, the level ofabstraction and the accuracy of domain knowledge in representation. The student who solved the problem successfully,presented via the verbal mode, selected the appropriateform of representation such as Punnett square and diagramof chromosomes. Her representation showed a high level ofabstraction and accurate domain knowledge. The studentswho solved the problem presented via verbal, graphical, andtable modes constructed the pedigree commonly. Thesuccessful students, however, transformed the original representationinto pedigree so perfectly that it accuratelyreflected the domain knowledge of the original representation. The students used their representation forunderstanding information of the problems, thereby reasoningthe right answers, visualizing and monitoring theproblem-solving process. These findings may provide educationalinsights for educators who seek to understand therelationship between genetic problem-solving processes andrepresentation.

영지(Ganoderma lucidum)균사체의 액체배양에 의한 세포외 수용성 다당류의 분획 및 항암활성

이신영,강태수,문순옥,류인덕,이명열 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.4

영지 균사체의 액체배양에 의하여 생산된 세포외 다당 시료를 분획하였고, 이들 각 분획에 대한 항암 활성을 균사체 유래 다당 분획들과 비교하면서 조사하였다. 배양여액으로부터 세포외 수용성 다당(BWS)을 얻었고, 이를 순차적으로 이온교환 및 겔 크로마토그라피 하여 BWS를 포함한 세포의 수용성 다당 분획, 총 5종을 얻었으며, 균사체 유래의 수용성 다당(MWS)에서도 세포외 다당과 동일한 방법으로 분획하여 총 5종의 분획을 얻어 대조구로 시용하였다. 세포외 다당 시료들의 항보체 활성(ITCH_50, %)은 15~30% 정도로 15~70%인 균사체 유래 다당 분획들의 값보다는 낮았으나, 이들 세포외 다당 분획들의 값보다는 낮았으나, 이들 세포외 다당 분획들중, BWS-DA와 BWS-DA-GI는 1000 ㎍/ml의 시료 농도에서 30% 정도의 매우 높은 활성을 나타내었다. MTT assay에서는 mouse leukemia L1210에 대하여 BWS-DN 및 MWS가 600㎍/ml의 농도에서 각각 86 및 89%의 높은 저해율을 나타내었으며, BWS-DA 및 MWS-DN의 경우는 3㎍/ml의 매우 낮은 농도에서도 32~35%의 저해율을 보였다. 또 human cell line인 COLO-205에 대해서는 BWS와 BWS-DA 및 MWS-DA가, 그리고 HL-60에 대해서는 BWS-DA와 BWS-DN 및 MWS-DN이 각각 300㎍/ml의 시료 농도에서 약 50%(IC_50)의 높은 저해능을 나타내었다. Exo-polysaccharide (BWS) obtained from submerged cultivation of Ganoderma lucidum mycelium was fractionated. Antitumor activity of their fractions was investigated in comparison with the mycelial polysaccharide fractions. Eight kinds (BWS-DN, BWS-DA, BWS-DN-GI, BWS-DA-GI, MWS-DN, MWS-DA, MWS-DN-GI and MWS-DA-GI) of polysaccharide fractions were obtained by DEAE-cellulose ion exchange chromatography and Sepharose CL-4B gel chromatography from BWS and MWS, which were isolated from culture fluid and mycelial cell, respectively. The anticomplementary activities (ITCH_50, %) of the exo-polysaccharide fractions showing 15% to 30% were lower than those of mycelial polysaccharide fractions showing 15% to 70%. The acidic fractions of BWS-DA and BWS-DA-GI fractionated from BWS, showed the highest activity of 30%. In the MTT assay, BWS-DN and MWS against mouse leukenia L1210 exhibited high inhibition ratio of 86 and 89%, respectively at the concentration of 600 ㎍/ml. High inhibition ratio of 50% (IC_50) was achieved for BWS, BWS-DA and MWS-DA fractions against human colon adenocarcinoma COLO-205 and for BWS-DN, and MWS-DN fractions against human leukemia HL-60 at the concentration of 300 ㎍/ml among the six polysaccharide fractions, respectively.

이신영,김근호,Lee, Sin-Yeong,Kim, Geun-Ho 대한흉부심장혈관외과학회 1986 Journal of Chest Surgery (J Chest Surg) Vol.19 No.1

At the Department of Thoracic and Cardiovascular Surgery, Hanyang university, from 1976 to 1984, 102 patients operated for isolated patent ductus arteriosus were studied. The correlation between the degree of left ventricular hypertrophy [LVH] and hemodynamic data, and postoperative changes of electrocardiographic findings were evaluated. The following results were obtained; [1] Of 102 patients with isolated patent ductus arteriosus, 78 patients [76.5%] were found to have LVH by EKG, preoperatively. [2] The patients with LVH had higher incidence of respiratory infection [79.4%] compared to patients without LVH. [3] Frequent physical findings in the patients with LVH were precordial bulging and P2 accentuation on auscultation. The typical continuous machinery murmur was not different in two group with or without LVH. [4] 66.1% of patients with LVH showed more than 56% of cardiothoracic ratio [CTR] on simple chest X-ray. 56.5% of patients without LVH showed less than 50% of CTR. [5] In the patients found to have LVH by EKG, the correlation between values of Svl+Rv6 and Qp/Qs in hemodynamic data was correlation coefficient 0.57 and between CTR and Qp/Qs was correlation coefficient 0.51. [6] In patent ductus arteriosus with LVH following surgery, the values of Svl+Rv6 was changed from preoperative 153.6$\pm$42.78% to 107.7$\pm$19.58% within 3 months and to 80.4$\pm$12.22%, which is within normal range of Svl+Rv6 on EKC, after 6 months.

The patient was 47-year-old male who had suffered from aphasia and hemiplegia of the right side, but mental state was alert. On physical examination, BP was 130/80 mmHg in the right arm, but not checked in the left arm. The pulses of the left common carotid, brachial, and radial arteries were not palpable. The pulses of the right femoral, popliteal, and dorsalis pedis arteries were weakly palpable. Brain CT Scan revealed cerebral infarction of the left hemisphere. Aortogram showed occlusion of the left common carotid, and the right internal carotid and common iliac arteries. Subclavian steal phenomena were observed in the delayed aortogram. Double extra-anatomic bypasses; Axillo-Axillar bypass and Femora-Femoral bypass, were performed in the local anesthesia at two stages, because of risk of major operation under general anesthesia. Postoperatively, all pulses except for pulse of the left common carotid artery were equally palpable. On discharge, the hemiplegia of the right side was improved and able to walk with assistance.
