The Comparision of Outcomes Between Lateral Rectus Muscles Re‐recession and Medial Rectus Muscles Resection in Recurrent Exotropia

Ko‐,i Chun,Sang‐,hoon Rah 대한안과학회 2008 Korean Journal of Ophthalmology Vol.22 No.2

Purpose: To compare the surgical outcomes between bilateral lateral rectus muscles (BLR) re‐recession and bilateral medial rectus muscles (BMR) resection in recurrent exotropia. Methods: The medical records of patients with recurrent exotropia who underwent surgery for intermittent exotropia during the 6 years from January 2001 to December 2006 and followed up for more than 6 months were reviewed retrospectively. Results: In group A, BLR recessions was performed at the first surgery and BLR re‐recession was performed at the second surgery. In group B, BLR recession was performed at the first surgery and BMR resection at the second surgery. Success rates at the last follow‐up after the second operation were 81.9% in Group A and 83.3% in Group B, showing no statical difference between the two groups. In group A, no significant underaction of the BLR was noted. Success rates were not statistically different between the 2 mm rerecessed subgroup and 3 mm re‐recessed subgroup. Conclusions: The results support the notion that BLR re‐recession successfully corrects recurrent exotropia without producing significant limitation of abduction.

Yanshan Lou,Hoon Huh,Younki Ko,Jiwoong Ha 한국자동차공학회 2010 한국자동차공학회 부문종합 학술대회 Vol.2010 No.5

This paper evaluates the performance of ductile fracture criteria on the prediction of forming limit diagrams (FLDs) of aluminum alloys. The ductile fracture criteria in this study include Cockcroft-Latham criterion (1968), Brozzo criterion (1972), Oh criterion (1979), Oyane-Sato criterion (1980), Clift criterion (1990) and Ko-Huh criterion (2007). The material properties and the experimental FLDs of 30 kinds of aluminum alloys are collected from researchers. Hosford79 yield function with normal anisotropy is applied. The Hollomon equation is utilized to describe the stress-strain relation of aluminum alloys. The experimental FLDs on the left hand side (LHS) are fitted linearly and the fitted straight line is applied to determine the limited strains of uniaxial tension and plane strain conditions. The material constants in the ductile fracture criteria are evaluated with the limited strains of uniaxial tension and plane strain tension conditions. The FLDs are predicted with these ductile fracture criteria with linear strain increment. The predicted FLDs are compared with experimental data. The results show that the FLDs predicted from Oyane-Sato and Ko-Huh ductile fracture criteria match the experimental data well for the LHS FLDs while other ductile fracture criteria overestimate the limited strain of LHS FLDs. For the right hand side FLDs, all these ductile fracture criteria do not perform well compared with experimental FLDs.

Despite of the absence of hyperacute rejection and acute humoral xenograft rejection, the organ graft of the a1,3-galactosyltransferase (GalT) gene knockouted (KO) and complement regulatory protein (CRP) expressing pig into a nonhuman primate is rejected by development of a thrombotic microangiopathy and/or a consumptive coagulopathy. Thus further introduction of genes to overcome the coagulation incompatibilities between pig and primate under GalT KO/CRP genetic background has been strongly suggested. CD73 (ecto-5'-nucelotidase) is an enzyme attached via a glycosyl phosphoinositol anchor to the extracellular membrane of endothelial cells, which catalyses the hydrolysis of adenosine triphosphate to adenosine. Loss of activity of CD73 results in activation and aggregation of platelets by a reduced capacity to convert nucleotides to adenosine. In previous study, we reported generation of GalT KO fibroblasts concurrently expressing membrane cofactor protein and produced cloned pigs by nuclear transfer of the fibroblast cells (1). In this study, we constructed a vector for expression of human CD73 under control of promoter of pig Icam2 gene expressed specifically at endothelial cells. This vector was introduced into porcine fibroblasts using the nucleofection technology, by which we had forty three fibroblasts clones carrying pIcam2- CD73 vector. Somatic cell nuclear transfer resulted in generation of two transgenic piglets survived.

Yanshan Lou,Soekbong Kim,Younki Ko,Hoon Huh 한국소성가공학회 2010 한국소성가공학회 학술대회 논문집 Vol.2010 No.10

This paper applies ductile fracture criteria for the formability prediction of various types of steel sheets to evaluate the accuracy of ductile fracture criteria on the prediction of forming limit diagrams (FLDs). The ductile fracture criteria studied in this paper include the Cockcroft criterion (1968), the Brozzo criterion (1972), the Oh criterion (1979), the Oyane-Sato criterion (1980), the Clift criterion (1990) and the Ko-Huh criterion (2007). The material properties and the experimental FLDs of 24 kinds of steel sheets are collected from researchers. Hosford79 yield function with normal anisotropy is utilized to model the yield surfaces of these steel sheets. The Hollomon equation is employed to describe the strain hardening behaviors. The material constants in the ductile fracture criteria are evaluated with the limited strains in the uniaxial tension state for Cockcroft criterion, Brozzo criterion, Oh criterion, Clift criterion and Ko-Huh criterion while the limit strains in both the uniaxial tension and plane strain tension conditions are used for the material constant evaluation in Oyane-Sato criterion. The FLDs are predicted with these ductile fracture criteria with linear strain paths. The predicted FLDs are compared with experimental data. The results show that the FLDs predicted from Oyane-Sato and Ko-Huh ductile fracture criteria match the experimental data well for the LHS FLDs while other ductile fracture criteria overestimate the limited strain in plane strain tension conditions. For the right hand side FLDs, all these ductile fracture criteria do not perform well compared with experimental FLDs.

박고훈,김익수 木浦大學校 敎育硏究所 2002 교육연구 Vol.15 No.-

전교조가 합법화된 상황속에서 전교조 교육이념의 인식정도를 알아보고, 교원노조법에 대해 교사들의 인식과 전교조 활동으로 인한 학교현장의 변화에 대한 교사들의 의견을 알아보고자 본 연구를 수행하였다. 본 연구에 따르면 교사들이 전교조에 가입한 동기는 교육제도의 모순을 개선하고 참교육실천에 관심이 있어서 이고 전교조의 교육이념에 대해 현장교사들은 대부분 꼭 필요한 이념이라고 생각하는 것으로 나타났으며, 전체의 반 이상의 교사들이 학습권을 침해하지 않는 범위내에서의 단체행동권과 교원노조의 교섭범위 및 활동이 법적으로 보장되어야 한다고 생각하였고, 교원노조의 정당가입과 정치활동에 대해서는 반반의 분포를 보였다. 마지막으로 전교조가 중점적으로 해야할 사업으로는 교육환경을 개선해야 한다는 의견이 지배적이었다. This study aims to examine the ideas and movement history of Korean Teacher's Union, to contemplate its influences on the teacher society and to consider the development objects and the roles to contribute toward the desirable teacher society. For the research, references about the ideas and movement history of Korean Teacher's Union and systems and organizations of teachers labor unions were examined and a questionnaire was used to investigate the teachers understanding of ideas and activities of Korean Teacher's Union. According to the results, most of the teachers joined in the association to improve inconsistencies of the education system. They are considering how they can apply the ideas of the association to the school education field. In addition, the right of collective action of the association should be admitted and all sorts of activities, which include the political activities and bargaining range of the association, should be guaranteed legally. The crises of public education collapse should be restored through improvement of educational environment and it should be the prior task of the association.

This experiment was performed to study physical and chemical changes of rapeseed oil. The condition used for hydrogenation was 0.02% nickel catalyst under H2 pressure 3.5 kg/cm2 and temperature 180℃. Four rapeseed oils were Yeongsan, Naehan, Halla and Asahi. Physicochemical changes of the hydrogenated rapeseed oil were examined by measuring iodine value, refractive index, melting point, fatty acid composition and trans -isomers. The results of experiment are as belows : 1.As compared with the changes of fatty acid between the rapeseed oil with low erucic acid and native rapeseed oil, it was shown the changes in erucic acid contents of erucic acid were 2% in rapeseed oil with low erucic acid and 40% in native rapeseed oil. Contents of oleic acid were 60% in rapeseed oil with low erucic acid and about 20% in native rapeseed oil. 2.IV and RI of the above oils were gradually decreased in going on hydrogenation, however, there were little differences between rapeseed oil with low erucic acid and native rapeseed oil. 3.Rapeseed oil with low erucic acid was approached to the desirable MP within two hours, but native rapeseed oil was not. 4.Trans-isomers of rapeseed oil with low erucic acid were shown 25% or so that of native rapeseed oil, 40% above. The results of experiment suggest that it is desirable to make a study of decreasing trans acid of hydrogenated rapeseed oil.

본 연구는 인간에게 보편적인 창의성을 부각시키려는 의도하에 이루어진 것으로 그 목적에 상응하는 행위로서 학업성취도에 대한 창의성의 설명력을 알아보고자 하였다. 또한 창의성이 지능과 상호작용을 이루면서 학업성취도와 관련이 있을 것이라고 예측하였다. 본 연구는 중다회귀분석으로 학업성취에 대한 지능과 창의성의 설명력을 알아보았다. 본 연구결과에 의하면 지능이 창의성의 유연성, 정교성 변인에 뒤이은 낮은 단계의 모형에 속함으로서 대인관계나 공간은 비교적 창의성의 변인들보다 낮은 설명력을 갖는다. 본 연구의 결과분석에 따라서 창의성이 지능과 함께 학업성취도를 설명할 수 있다는 것은 창의성 변인이 학업성취를 예측할 수 있는 것으로, 창의성에 대한 보편적 접근과 연구가 이루어질 것으로 기대한다. This study is to find out a good method for the purpose of maximizing the effectiveness of school management, by way of making clear the types of vice principals's leadership and the things which influence on its job results within organization, and coinciding in opinion and minimizing the conflict between vice president and teachers. In conclusion, because teacher's level of mature was generally high in school situation, it is desirable for vice principal to do the role of entrusting leadership, creating permissive atmosphere. Furthermore, through opening him/herself by exposing him/herself to the members of the organization, vice principal should reduce the conflict between members and enlarge the leadership area and effectiveness through feed-back.

There is currently a debate on whether theology can reconcile with science undertaken between Christian scientist, Jong-Hak Woo and reformed theologian, Byung-Hoon Kim/Byung-Hoon Wo. The former argues that religions can balance with science, accepting evolution or evolution theory. Conversely, the latter claims that reformed theology cannot reconcile with science. The purpose of this study is to understand the ideas of Christian scientist (Jong-Hak Woo) and of reformed theologian (Byung-Hoon Kim/Byung-Hoon Woo) and to suggest their practical meaning for the Korean Church. This paper will proceed as follows: First, section two explains the aforementioned research and its arguements by employing three views: 1) interpreter’s academic background 2) interpreter’s community/position, and 3) interpreter’s discourse. The three views help to analyze the reason/situation of interpreter (number 1 and 2) and the effect of interpreter’s argument (number 3). Second, the next section offers suggestions regarding the meanings of my paper for today’s Korean churches. Finally, I will organize the previous sections, set out my view, and deal with limits of my paper and future tasks.
