북한이탈주민의 장애정체성 연구 : 중도 신체 장애인을 중심으로

윤세라,허준기 한국장애인재단 2018 장애의 재해석 Vol.2018 No.-

본 연구는 장애를 가진 북한이탈주민이 어떠한 장애정체성을 가지고 있으며, 정체성의 형성과정에서 개인의 생애사적 맥락과 남북한의 사회적 맥락이 어떻게 영향을 미쳤는지 보고자 한다. 장애정체성은 장애 정도, 성별, 연령, 학력 등의 개인 요인뿐만 아니라 장애에 대한 사회적 지지, 해당 국가의 복지제도 등 사회적 맥락에도 영향을 받는다. 연구에서는 이러한 복합적인 요인을 파악하기 위하여 구술사 연구방법의 질적 연구를 진행하면서도, 기존의 양적 방법론에서 장애정체감을 검토할 때 고려하였던 요인들을 함께 파악하여 인터뷰를 진행하였다. 또한, 장애를 갖게 된 시점(사회적 공간), 성별, 남한에서의 학업・사회활동 경험, 연령대, 장애정도 등의 여러 가지 배경을 가진 사람들을 인터뷰 대상자로 선정하여 다양한 맥락을 파악할 수 있도록 하였다. 연구 결과, 장애를 가진 북한이탈주민의 장애정체성과 그 형성과정은 다음과 같은 특성을 보였다. 첫째, 장애인보다는 북한이탈주민의 정체성이 더 강하게 나타났다. 둘째, 북한에서 겪었던 장애인 차별의 사회적 맥락이 강하게 영향을 미쳐 장애 초기 장애를 은폐하고 비장애인처럼 살아가는 모습을 보였다. 셋째, 장애인 집단, 가족, 사회복지학과 등의 다양한 사회적 지지가 각각의 정체성에 영향을 주었다. 한편, 연구에서는 장애 초기 나타나는 자기부정 등 중도 장애가 갖는 보편적인 특성들이 참여자들에게도 보편적으로 나타났다는 점을 확인할 수 있었다. 이 연구는 ‘북한이탈주민’과 ‘장애인’이라는 이중적 차별지위 속에서 그들이 겪었던 경험에 주목하고 검토하면서, 또 다른 정체성의 시각에서 남한 사회를 재해석 할 수 있었다. 또한, 장애를 가진 북한이탈주민 개인의 정체성뿐만 아니라 그들이 받아들인 북한과 남한의 장애에 대한 인식도 살펴볼 수 있다는 점에서 의의를 가진다.

메탄 플라즈마 분해에 의해 제조된 카본블랙 도전재의 전기화학적 특성에 대한 연구

윤세라,이중기,조원일,백영순,주재백,조병원,Yoon, Se-Rah,Lee, Joong-Kee,Cho, Won-Ihl,Baek, Young-Soon,Ju, Jae-Beck,Cho, Byung-Won 한국전기화학회 2003 한국전기화학회지 Vol.6 No.1

메탄의 플라즈마 열분해 방법에 의해 제조된 카본블랙을 $2\times10^{-2}torr$진공상태에서 $800,\;1300,\;2100^{\circ}C$의 온도로 열처리하여 원시료를 포함하여 물리적$\cdot$화학적 특성이 다른 4개의 시료를 준비하였다. 이 시료들을 리튬이차전지 양극 활물질인 $LiCoO_2$의 도전재로 사용하여 $Li/LiCoO_2$ 반쪽전지를 구성하고 변화된 도전재의 특성에 따른 셀의 전기화학적 특성 차이를 조사하였다 시료를 열처리하였을 때 표면화학그룹이 제거되고 전도도가 높아지면서 도전재로 사용하였을 때 사이클 특성 및 초기 방전용량이 향상되었다. 그러나, $2100^{\circ}C$에서 열처리한 시료를 도전재로 사용한 경우에는 사이클 특성 및 rate capability가 저하되는 것으로 나타났다. 이것은 플라즈마 블랙의 열처리에 의한 구조 변화에 따른 전극 내 분산 특성의 변화가 전도도 특성과 복합적으로 작용하여 제작한 셀의 전기화학적 특성에 영향을 미치기 때문으로 사료된다 열처리 온도가 높아질수록 카본블랙 표면의 관능기가 제거되면서 플라즈마 블랙의 전도도가 증가하였으나, 흑연화의 진행으로 나타난 agglomeration의 증가가 전극 내 분산 특성을 저하시키는 것으로 사료된다 그 결과 $800^{\circ}C$에서 열처리한 시료의 사이클 특성이 가장 우수하였다. Plasma carbon black(PB) which prepared by plasma pyrolysis of methane was treated at 800, 1300 and $2100^{\circ}C$ under $2\times10^{-2}$ torr. Four different samples including raw PB were added to $LiCoO_2$, cathode active material of lithium secondary battery, to investigate effects of properties of plasma black as conductors on electrochemical characteristics. Based on our experimental results, PB conductors with low amount of surface functional groups and high electrical conductivity enhanced the cyclability and the initial discharge capacity. However, deterioration of rate capability and cyclability were observed (or the plasma black treated at $2100^{\circ}C$ For the plasma black conductor prepared from plasma pyrolysis, the effects of properties of carbon black on electrochemical characteristics were combined results of changes in electrical conductivity and structural properties such as agglomeration of plasma black. The conductivity of plasma black increased with treatment temperature, while dispersion of plasma black decreased. As a result, the high cyclability of cell was observed at $800^{\circ}C$ of heat treatment temperature.

급성 뇌경색증에서 Transcranial Doppler의 진단적 가치에 관한 연구

윤세라,이기재,김호균 인제대학교 1999 仁濟醫學 Vol.20 No.1S

Transcranial doppler(TCD)의 두개내 혈관협착, 특히 다발성 협착의 진단의 적용에 대해서 알아보았다. 현재 관용적으로 쓰이고 있는 TCD상의 혈류속도의 증가만을 기준으로 하였을 때와 혈류속도외에 혈류의 형태학적인 변화, 측부 순환의 양상, 혈류속도의 감소, 좌우 비대칭성 등의 다양한 진단 지표를 고려하였을 때의 결과를 뇌혈관촬영술과의 상관관계에 비추어 비교하여 보았다. 두개내의 다발성 혈관협착의 빈발성과 그에 따른 복잡한 혈류양상 때문에 혈류속도 외에 다양한 진단 지표를 동시에 고려하였을 때가 TCD의 민감도, 특이도, 및 정확도를 증가시켜 TCD의 진단적 가치를 높임을 알 수 있었다. Objectives: The purpose of this study is to evaluate the usefulness of morphologic changes and collateral flow patterns in addition to velocity criteria using transcranial doppler(TCD) in detection of intracranial vascular stenosis, especially in cases of multiple stenoses. Methods and Materials : Medical records, angiography, and TCD findings were reviewed in 86 patients with acute cerebral infarction who underwent both cerebral angiography and TCD examination. Angiography was performed after TCD within a week. Angiography and TCD were interpreted blindly by neurologist and neuroradiologist. TCD was interpreted, using the velocity criteria according to the previous normal data of Yonsei medical collage, and to the morphologic changes and collateral flow patterns, retrospectively. Results: Total 373 sites of patients, who had good windows of TCD at intracranial portion of carotid siphon(siphon), proximal portion of middle cerebral artery(M1), and basilar artery were evaluated. Total 67 sites(46 patients) of stenoses were found 28 sites of M1, 30 sites of siphon, and 9 sites of basilar artery, Fifty eight of 67 sites had more than one site of intracranial stenosis. Among them, 43 sites had multiple stenoses within a vascular territory proximally and distally. When we used mean velocity as a sole parameter of diagnostic criteria, the overall sensitivity, specificity, and accuracy of TCD in detection of the stenosis at M1, siphon. and basilar artery were 19.4%, 85.0%, and 79.4%, respectively. When abnormal flow waveforms, collateral flow patterns, and decreased MV were considered together, they were improved to 55.2%, 91.1%, and 78.8%, respectively. When these parameters were considered in patients with multiple stenoses, one of the most confusing factor of diagnosis, false negative ramie was decreased markedly. The sensitivity was increased to 53.5%, close to that wish single stenosis (58.3%), resulting in better correlation with angiography and TCD examination. Conclusion: Owing to the high frequency of multiple stenoses and iris complex flow pat terns in intracranial stenosis, TCD may not be effective screening test for intracranial vascular stenosis if increased mean velocity is used as a sole criteria. So it seems to be better in detection of intracranial vascular stenosis that variable parameters such as changes in flow waveforms, collateral flow patterns, decreased mean velocity, and asymmetry index are considered simultaneously.

統合敎科書의 分析을 통한 問題點과 改善方案

The integrated textbook project in Korea has been developed continually since the 4th Curriculum Reform in 1981. The 5th Curriculum Reform as a try to get rid of sequent problems followed by the curriculum integration management as; lack of consistency in goals, contents, instruction and evaluation which are resulted from integrating textbooks when the curriculum were organized segmently; biased instruction in some courses from excessive integration; and short of understanding in integrated instruction and segmental teaching in educational field, and so on. There are some certain features of the 5th Curriculum Reform: On the distribution of curriculum and class hour allocation, integrated curriculum was newly provided in the 1st and 2nd grade elementary school courses. The Korean and arithmetic in those grades separated independently from the integrated textbooks. Increasing annual class hours, rationally controlled weekly class hours and the realization of extra curriculum hour operation were one of the features. There has been a lot of improvement in the integrated textbook contents as well. Thanks to the theoretical, practical researches and the acting teachers' opinions about the integrated textbooks, real changes have been made in the theory and practice. Nonetheless, there are quite many unsolved problems brought down by the lack of recognition about the integrated curriculum and textbooks; by parents' insufficient understanding and partial teachers' short of respect toward students during the integrated curriculum course work; and by other various factors. The purpose of research is to bring forth effective management of the integrated textbooks, by demonstrating problems of them and suggesting a few improvement measures. First, current integrated textbooks do not wholly exclude the test-centered education atmosphere, which are produced in the base of conventional curriculum. Therefore, sufficient researches about the vertical and cross relationship in the curriculums are needed. Second, teachers should be able enough to establish to the original educational purposes by operating integrated textbooks. Third, to regard the nation's education finance, it is impossible to reform the unreasonable environment of education at once. However, it is most urgent to reduce student numbers in a class and to expand the classroom size. Forth, instructing manuals for teachers must demonstrate educationed philosophy and ideology underlying as well as concrete teaching methods in order for teachers to recognize enough. Fifth, integrated textbooks now in use have many parts intermingling each other. So it is needed to reorganize the textbooks attaching importance to interests, functions and activities. There might be other issues about superficial system of textbooks and how to reapply the textbooks.

Purpose : To evaluate the characteristic sequential MRI findings of cortical laminar necrosis Materials andMethods : We retrospectively reviewed the MRI findings of 11 patients with clinical signs of hypoxic brain damagewho showed findings of cortical laminar necrosis with definite time of onset. Three were men and eight were women; they were aged between 27 and 74 (mean 59.3)years. All patients underwent imaging with a 1.0-T MagnetomImpact(Siemens) ; follow-up MR examinations were performed in five. Results : The watershed zones in theparietooccipital, frontoparietal and temporoparietal cortex were involved in eight cases, whereas the other areasinvolved were the frontal lobe in two cases and the temporal lobe in one. In one case, MRI obtained two days latershowed brain swelling demonstrating obliteration of cortical sulci and high signal intensity of subcortical whitematter on T2WI. In five cases, MRI obtained between two and three weeks later showed gyriform high signalintensity along the cortex on T1WI, cortical high and subcortical low signal intensities on T2WI in four cases,and gyriform enhancement on gadolinium-enhanced scans in three cases. MRI obtained between three and four weekslater in three cases showed subcortical high signal intensity on T2WI in two cases and gyriform cortical highsignal intensities on T1WI and gyral enhancement in all cases. MRI obtained after 50 days in four cases includingtwo of follow-up MR, showed cortical gyriform high signal intensity on T1WI in all cases and subcortical highsignal intensity on T2WI and mild gyriform enhancement on gadolinium-enhanced scans in three cases. In twofollow-up studies, the lesions had become more discrete and larger. Conclusion : Cortical laminar necrosis due tohypoxic brain damage shows relatively characteristic MR findings according to the stage. Therefore, MR imagingseems to be useful diagnostic tool for the evaluation of cortical laminar necrosis due to hypoxic brain damage.

Background Previous studies have reported various advantages of general squat for functional activities. However, no study has reported the effect of lower leg muscle activity during squat on ankle stability with different supporting surface conditions. Purpose To investigate the effect of various support surfaces on lower leg muscle activation during squat performance and identify an effective way to prevent ankle injuries by increasing ankle stability. Study design Cross-sectional study. Methods Twenty healthy adults were recruited to compare lower leg muscle activation during squat performance on various support surfaces. Electromyographic activity was measured for tibialis anterior (TA), peroneus longus (PL), medial gastrocnemius (GCM), and lateral GCM muscles. Lower leg muscle activity during squat performance was calculated using mean value measured three times on each support surface. Repeated 3 × 2 two-way ANOVA measurements (surface conditions × leg sides) with Bonferroni’s correction was used to compare lower leg muscle activity from both sides on various support surfaces during squat exercise. Results TA muscle activity during squat performance under balance pad (BP) condition was significantly greater than that under togu (TG) condition (p<0.05). PL muscle activity during squat performance was significantly greater under bottom floor (BF) condition than that under BP or TG condition (p<0.05). Medial GCM muscle activity during squat performance was significantly greater under BP condition than that under BF or TG condition (p<0.05). TA and medial GCM muscle activities were the highest under BP condition, followed by those under BF and TG conditions. PL and lateral GCM muscle activities were the highest under BF condition, followed by those under BP and TG conditions. Conclusions For anteroposterior muscles of the lower leg, squat exercise needs to be performed on a slightly unstable support surface such as a BP. For lateral muscles of the lower leg, squat exercise needs to be performed on stable support surface such as BF.

일본 결혼여성이민자의 한국생활 적응에 관한 연구

윤세라,고진호 한국국제문화교류학회 2020 문화교류와 다문화교육 Vol.9 No.2

In this study, we examined the process of adapting Japanese married women to life in Korea through qualitative research. In the process of adapting to Korean life, they had serious conflicts such as cultural differences and satisfaction with their husbands and families. In particular, I would like to explain that it has an unique aspect compared to families made up of female spouses from other Southeast Asian countries. As a result of the study, the following conclusions were obtained. First, Japanese marriage women had the burden of assimilating their emotional expressions and cultural differences to Korean culture and promoting them to become Korean. It was also found that the coercion of one-sided culture, rather than understanding and tolerance, resulted in resistance or antipathy. Second, it was difficult to be positioned as a member of the in-laws family in Korea`s family relationship. This is because the Korean mother-in-law is demanding a role rather than understanding her daughter-in-law from abroad. The implications of this study are that in order to embrace multicultural families and Japanese married women imigrants, our society should pay attention to their culture and think about the differences, not the coercion of “Korean” culture and unilateral acceptance of Korean family culture by in-laws. It is also said that education for Japanese female marriage immigrants should have a good influence on adapting to life in Korea with a comprehensive and subdivided education that takes into account their characteristics. 본 연구에서는 한국사회에서 일본 결혼여성이민자들의 한국생활 적응과정을 질적연구로 살펴보았다. 그들은 한국생활에 적응하는 과정에서 문화적 차이, 남편과 가족에 대한 만족감 등의 갈등 양상이 심각했다. 특히, 다른 동남아국가 출신 여성 배우자로 구성된 가정에 비해 특이한 측면을 내재하고 있음을 설명하고자 한다. 연구 결과, 다음과 같은 결론을 얻게 되었다. 첫째, 일본 결혼여성이민자들은 자신의 감정적 표현과 문화적 차이를 한국문화에 동화해서, 한국 사람이 되도록 촉진시키는 것의 부담을 안고 있었다. 또한 이해와 관용보다는 일방적인 문화의 강요가 반발이나 반감을 갖게 되었음이 나타났다. 둘째, 한국의 가족관계에서 시댁에서의 자리매김이 어려운 점이였고, 이는 한국 시어머니가 외국 출신 며느리를 이해하기 보다는 역할을 요구하고 있기 때문이라고 언급하고 있다. 본 연구를 통한 시사점은 다문화가정 및 일본 결혼여성이민자들을 포옹하기 위해서는 ‘한국식’ 문화의 강요와 시댁 식구들에 의한 한국 가족 문화의 일방적 수용이 아닌 그들의 문화에 관심을 갖고 그 차이점에 대해서 우리사회가 고민을 해 야 한다는 것이다. 또한 일본 결혼여성이민자들을 위한 교육이 그들의 특징이 고려된 일괄적이고 세분화 된 교육으로 한국생활적응에 좋은 영향력을 주어야 한다는 것이다.
