Background: Non-variceal upper GI bleeding (NVUGIB) is a common medical problem that has signifi cant association with morbidity and mortality. Angiographic detection and subsequent transarterial embolization (TAE) is a primary treatment option when medical and endoscopic treatments fail. We investigated clinical factors that could affect the success of the angiographic detection and prognosis after TAE in patients with NVUGIB refractory to endoscopic therapy. Methods: A retrospective analysis of the clinical data was done in patients with failed endoscopic treatment who underwent angiography for the treatment of acute NVUGIB between May 2002 and May 2013. Patients were divided into detection or non-detection groups according to the presence of bleeding stigmata in angiographic fi nding. Rebleeding defi ned as subsequent bleeding event within 7 days and mortality within 30days were analyzed as outcome parameters after TAE following detection in angiography. Results: A total 45 patients 37 (male, mean age, 65.9±14.9 years) were analyzed and classifi ed as a detection group (n=25, 55.5%) and non-detection group (n=20, 44.6%). Peptic ulcers were the most common cause of refractory NVUGIB. Larger transfusion amount (5.7±3.9 unit vs. 3.5±2.8 unit; P=0.03), prolonged aPTT level (34.2±17.3 sec vs. 21.8±13.8 sec; P=0.01) and short time interval between last endoscopy and angiography (17.5±25.9 hours vs. 34.3±59.5 hours; P=0.04) were found to be signifi cant factors for predicting angiographic detection. TAE was performed in all patients detected in angiography. Rebleeding (44%) was significantly associated with higher Rockall score (8.3±1.5 vs. 6.6±2.4; P=0.046) and mortality (12%) was signifi cantly associated with higher Rockall score (9.3±0.6 vs. 7.1±2.2; P=0.002) and higher level of BUN (55.3±47.4 vs. 27.6±17.4; P=0.01). Conclusions: Clinical characteristics associated with angiographic detection in patients with NVUGIB refractory to endoscopic therapy were severe bleeding, bleeding tendency and early angiographic intervention. The Rockall score is useful parameter for predicting rebleeding and mortality after TAE.

최종태(Jong-Tae Choi) 한국경영사학회 2012 經營史學 Vol.61 No.-

본고는 선경의 창업자인 담연 최종건 회장의 리더십과 사회적 책임경영을 고찰하는데 있다. 선경(SK)은 창업자인 담연 최종건의 창업정신과 경영이념을 바탕으로 하여 세계 기업으로 성장하였고, 한국경제의 발전에 크게 기여한 기업집단이다. 선경은 1945년 출발한 이래 1953년 전쟁으로 폐허가 된 이 땅에 섬유산업의 씨앗을 뿌리고 화학산업을 일으켰을 뿐만 아니라, 「석유에서 섬유까지」의 수직계열화를 실천하기 위한 터전을 닦아놓아 그 후계자로 하여금 완성하게 하였다. 오늘날에도 창업자의 정신적 유산을 이어 받아 기업의 면모를 일신하면서 세계적 기업으로 성장과 발전을 거듭해왔고, 다양한 산업분야에 걸쳐 한국경제를 이끌어 가는 견인차의 역할을 하고 있다. 이렇듯 SK그룹이 한국경제를 주도하며 세계적인 기업집단으로 성장하는 과정 속에서 그룹 창업자인 담연 최종건 회장의 시대(1953-1973)는 도전과 개척의 역사였다. 그는 개척적인 도전정신과 정도경영을 통해 창의적이고 의욕적인 경영의 멋을 보여 주었다. 올바른 판단력, 그리고 과감한 결단력 과 실천력은 선경(SK)의 도전 정신과 혁신경영의 DNA와 문화로 자리매김 토록 하였다. 담연 최종건 창업회장의 개척자정신, 도전정신, 사업 보국의 정신이 선경(SK)그룹의 창업을 낳았고, 인재와 기술, 그리고 신용을 중시한 경영이념을 바탕으로 한 그의 창조적 리더십과 공동체적 사회책임경영은 짧은 생애였지만 SK그룹 100년의 기반을 닦았고, 한국경제 발전에 큰 족적을 남겼다. 담양의 리더십의 특성은 창조적 카리스마와 혁신적 슈퍼 리더십으로 규정지울 수 있고, 그의 사회적 책임경영의 특성은 공동체적 정신과 사업보국정신에 입각한 기업차원을 넘어선 사회와 국가차원의 실현으로 규정지울 수 있다. The paper aims to reflect on the leadership and social responsibility of business management of Chey, Jong-Kun, the founder of SK Group. Sun Kyung or SK has grown to be a globally leading business entity by inheriting the spirit of his entrepreneurship and business management philosophy, significantly contributing to the economic development in Korea. Since its foundation in 1945, Sun Kyung has planted the seeds of industrial development in the textile and chemical industry in a war-torn country. With his management philosophy of pioneership and ethical management, he exemplified creative and passionate management practices. His leadership was creative charismatic and innovative super leadership, which has its roots in his sincerity, his spirit of challenge, perseverance, tenacity and the management practices based on innovation and technology. Damyeon Chey, Jong-Kun devoted efforts in implementing socially responsible business management practices. As he believed that the business management should be socially responsible contributing to communities based on the community, he invested to create values for the society and the country. Business entities and the industrial relations today can learn the lessons and draw implications from his business management on CSR.

Tae‑Wook Na,Hyung‑Ki Park,박창수,Hyung‑Don Joo,Jong‑Tae Park,Heung Nam Han,Nong‑Moon Hwang 대한금속·재료학회 2018 METALS AND MATERIALS International Vol.24 No.6

In Fe–3%Si steel, the hot rolling process affects not only the hot rolling texture but also the primary recrystallization texture. Here, the effect of asymmetric hot rolling was studied by comparing the difference in the texture evolved between asymmetricand symmetric hot rolling. The effect of asymmetric hot rolling on the texture of primary recrystallized Fe–3%Si steel wasalso studied. The symmetric hot rolling of Fe–3%Si steel produces a rotated cube texture at the center but Goss and coppertextures near the surface. Asymmetric hot rolling tends to produce Goss and copper textures even at the center like thetexture near the surface. After primary recrystallization, the dominant texture at the center changes from {001} <210> to{111} <112> and the new texture has a higher fraction of the grains which make the low energy boundary with Goss grainsthan that of symmetric hot rolling.

Jong‐In Jin,Byung‐Hyun Choi,Seong‐Su Kim,Hyun‐Tae Jo,Il‐Keun Kong 한국동물생명공학회(구 한국동물번식학회) 2011 발생공학 국제심포지엄 및 학술대회 Vol.2011 No.1

The objective of this study was to evaluate the comparison of production efficiency of oocytes and OPU (ovum pick‐up) derived embryos of Hanwoo with Holstein. The OPU session of each species (6 cows) was carried out from the Hanwoo (106 sessions) and Holstein (114 sessions) at intervals of 3 4 days (2 times per week) for 3 months. Cumulus‐oocyte‐complexes (COCs) retrieved were classified into 4 grades by the status of oocyte cytoplasm and cumulus cells. The COCs collected were matured in vitro in TCM‐199 supplemented with 10% FBS, 10 mg/ml FSH and 1 mg/ml estradiol‐ 17β in 5% CO2 and over 99% humidity for 24 h. After 24 h co‐incubation with post‐thaw sperm, the presumed zygotes were cultured in CR1aa medium with 4 mg/ml BSA for 3 days and then changed CR1aa medium with 10% of FBS for another 3 4 days. The Mean number of aspirated follicles and collected oocytes were not significantly different between Hanwoo and Holstein spacies (10.4±0.42 vs. 11.4±0.41 and 7.5±0.38 vs. 6.1±0.37 per session). But the collection rate of oocytes from aspirated follicles were significantly higher in Hanwoo (72.8%) than that in Holstein (53.6%) (p< 0.05). Furthermore, the average number of good quality oocytes (Grade I and II) was 5.9±0.28 and 4.1±0.27 (Mean±SD), and the cleavage rate and the development rate to blastocysts was significantly (p<0.05) higher in Hanwoo (40.0%) than Holstein (21.6%). The OPU derived embryos of Hanwoo were transferred 83 times into 52 recipients and then 42 calves were produced from 44 pregnancy recipients. In conclusion, the efficiency of OPU derived embryo was significantly different between Hanwoo and Holstein species. In vitro culture system for OPU derived embryo production should be optimized for industrialization and the improvement of livestock.

변성태,김종훈,정태동,구태만 울산대학교 1996 공학연구논문집 Vol.27 No.1

크레인 구동용으로 antiparallel converter의 반도체 전력회로에 마이크로 제어기를 사용한 직류전동기의 속도제어 시스템에 대한 안정영역을 해석한다. 먼저 불연속 전류인 경우 converter의 비선형특성으로 인하여 전동기 속도제어 능력이 저하되므로 이를 보상하는 방식을 제안한다. 이 converter와 직류전동기를 포함한 전체 속도제어 시스템을 이산형 상태방적식으로 모델링 한 후, 각 제어기 이득에 대한 안정영역을 해석한다. The stability regions for microcontroller-based dc motor speed control system driven by antiparallel converter, which has been used as the crane drive, are analyzed, first as the performance of motor speed control is deteriorated due to nonlinear characteristics of the converter in the discontinous current state, the method to compense for nonlinear characteristics of the converter is suggested. The overall dc motor speed control system including the converter and dc motor is represented by a discrete-time state equation, and then the stability regions for gains of controllers are dervied.

김태종(Kim Tae-Jong),엄재근(Eom Jae-Gun) 한국경영교육학회 2020 경영교육연구 Vol.35 No.6

[연구목적] 본 연구의 목적은 세계 가전 시장 점유율 1위를 달성한 LG전자 생활 가전사업을 ser-M Framework으로 분석을 하고, 기업의 Global 경쟁력을 확보하기 위한 최적의 메커니즘 사례를 연구하여 시사점을 도출하고자 한다. [연구방법] 연구대상은 Global 가전 기업 중 세계 생활가전 시장 점유율 1위를 달성한 LG전자 생활가전이다. 지금까지의 가전 산업에서 가전 기업의 연구에 대해서 대부분 미시적 관점에서 연구가 되어 왔으나 거시적이고 포괄적인 관점의 연구는 미흡하였다고 여겨진다. 이에 ser-M Framework를 이용한 대표적 가전 기업의 메커니즘을 분석하여 LG 시그니처라는 고가격과 프리미엄 브랜드 전략으로 성공한 메커니즘을 연구해 보고자 한다. [연구결과] 사례 분석 결과, 국내의 기업들은 일반적으로 초기 창업주의 강한 리더십으로 사업을 성장시키는 S-E-R 메커니즘이 대부분 작동하고 있었으나, LG전자 생활가전의 경우 신기술 변화에 따른 제품 고급화 및 프리미엄 브랜드 전략을 통해 성과를 창출하였으며 주체가 환경 분석을 통하여 경영 전략에 탁월한 의사결정으로 인한 메커니즘이 작동하였다. 따라서 첨단기술로 접목된 프리미엄 가전 시장이 성장하는 환경(E)에 적극적으로 대응하고, 기존의 연구개발 조직을 통폐합하여 자원을 재배치함으로써 프리미엄 제품을 개발시키는데 있어 우수 인력을 활용하는 메커니즘이 가장 적절하였다고 할 수 있다. [연구의 시사점] 본 연구는 ser-M 기반의 가전 기업 메커니즘을 연구에 있어 처음으로 가전 기업의 주체(S), 환경(E), 자원(R), 메커니즘(M)을 통합적으로 고찰한 것이 매우 의미가 깊으며, 대표적 가전사업의 사례 연구라는 것에 의의가 있다. [Purpose] The purpose of this study is to analyze LG Electronics’ household appliances business, which has achieved the highest share of the global home appliance market, as a service-M framework, and to derive implications by studying best mechanism cases to secure the company’s global competitiveness. [Methodology] LG Electronics’ household appliances, which have achieved the largest share of the global home appliance market among global home appliance companies, are subject to research. While most of the research in the consumer electronics industry has been done from a microscopic point of view, it is considered insufficient to do so from a macro-and comprehensive point of view. Therefore, we would like to analyze the mechanisms of representative home appliance companies using the server-M framework and study the mechanisms that succeeded with the high price of LG Signature and premium brand strategy. [Findings] As a result of the case analysis, most of the S-E-R mechanisms that grow businesses with strong leadership of early start-ups worked, but LG Electronics’ household appliances generated results through product advancement and premium brand strategies due to new technology changes, and the main body worked through environmental analysis. Therefore, the most appropriate mechanism was to actively respond to the growing environment (E) of the premium home appliance market, and to utilize the best manpower in developing premium products by consolidating existing R&D organizations and relocating resources. [Implications] This study is very meaningful in that the first integrated consideration of the subject (S), environment (E), resource (R), and mechanism (M) of a consumer electronics company is a case study of a representative consumer electronics business.

Increased expression of P53 and Bax in the spinal cords of rats with experimental autoimmune encephalomylitis

문창종,김승준,위명복,김희석,정종태,박전홍,지영흔,Tanumab, Naoyuki,Matsumoto, Yoh,신태균 濟州大學校 農科大學 動物科學硏究所 2000 動物科學論叢 Vol.15 No.1

The expression of pro-apoptotic molecules, p53 and Bax, in the spinal cord of rats with experimental autoimmune encephalomyelitis (EAE) was examined. Apoptosis was confirmed by the terminal deoxynucleotidyl transferasemediated dUTP nick end-labeling (TUNEL) method. TUSEL (+) apoptotic cells were mainly either ED1 (+) macrophages or T-cells in the parenchyma of E N . Western blot analysis showed that both p53 and Bax expression significantly ( p < 0.01) increased in the spinal cords of EAE rats at the peak stage, and thereafter declined. An immunohistochemical study showed that inflammatory cells (notably T cells) in the parenchyma express p53 and Bax, while brain cells, includng neurons and glia, were devoid of these nuclear staining of these molecules. The nuclear expression of p53 largely matches apoptotic cells in the parenchyma of EAE. These finchngs suggest that pro-apoptotic molecules, p53 and Bax, may play an important role in eliminating T cells in the parenchyma in EAE.
