Transcatheter aortic valve implantation is an alternative to open heart surgery in high risk patients with severe aortic stenosis. High mortality and complications related to cardiopulmonary bypass for conventional open heart surgery can be avoided with this new less invasive technique. In case of concomitant severe arterial disease, the transapical approach is recommended rather than transfemoral access. An 80-yr-old man with symptomatic aortic stenosis and who had very high surgical risk factors such as diabetes mellitus, hypertension, a history of stroke, bronchial asthma including poor pulmonary function and hepatocellular carcinoma was treated with a transapical aortic valve replacement. The expected mortality in this patient was 25.4% by Euroscore if we performed the conventional aortic valve surgery. The patient was discharged and was well at the 45 follow-up days. We report the first case of successful transcatheter transapical aortic valve implantation which is available recently in Korea.

Management of ischemic mitral regurgitation (MR) is challenging. The aim of this study was to investigate long-term clinical and echocardiographic results of restrictive mitral annuloplasty for ischemic MR. From 2001 through 2010, 96 patients who underwent myocardial revascularization with restrictive mitral annuloplasty using a vascular strip for ischemic MR were analyzed. Patients were stratified into two groups based on left ventricular ejection fraction (LVEF): group I, n = 50, with LVEF > 35% and group II,n = 46, with LVEF ≤ 35%. The early mortality rate was 2.1% (2/96) and the late cardiac mortality rate was 11.5% (11/96). MR grade was reduced at discharge (0.8 ± 0.7) but increased during follow-up (1.1 ± 0.8, P = 0.001). There was no intergroup difference in terms of freedom from recurrent MR ≥ moderate eight years after surgery (94.1% ± 5.7%, group I vs 87.8% ± 7.2%, group II; P = 0.575). NYHA functional class (odds ratio [OR], 2.2; P = 0.044) and early postoperative residual MR ≥ mild (OR, 25.4;P < 0.001) were independent predictors of recurrent MR. Restrictive mitral annuloplasty using a vascular strip is effective in ischemic MR. It is important to avoid early postoperative residual MR.

The Strategy of Introduction on e-Learning System Performance in the Corporate Education & Training Settings†Chung, Dong-Seop*E-learning programs in corporation are increasing dramatically every year. As the Internet and Multimedia tool spreads into every corner of corporate work settings, the paradigm of education has changed. With this change, many corporation educational tool, including education division formed cyber -education. As the human resources development is perceived as a critical factor for organization 's success. This study examines to what extent trainee's transfer effect is the influenced by individual learning performance and work influence variables. Among many successful factors for corporation's e-learning, such as high quality contents, social interaction, instructional design strategies are the top priorities to consider to produce the best results from e-learning performance.The purposes of this study were to understand the relationship between e-learning influence variables and learning performance, and to analyze the mediating effects of the influence variables and learning effectiveness in e-learning training program. Three hypotheses are developed based on literature reviews and tested by questionnaires survey data. Drawing upon the findings, we discuss their managerial implications. The limitations of this research are also discussed with future studies.攀†This paper was supported by Korea Research Foundation Grant(KRF-2001-041-C00314)* Assistant Professor, Department of Business Administration, Kyungsung University 攀攀

The author made a study on sex chromatin of smears obtained from the various organs of sexually intact Korean fetus ranging from 4 months to 10 months old and adults of both sexes, using hematoxylin-biebrich scarlet-fast green method by Guard. The results were as follow: 1) The organs in which the sex chromatin could be demonstrable are skin, vagina, oral mucosa, esophagus, stomach, small intestine, large intestine, salivary gland, pancreas, thyroid gland, lung, heart, kidney, uterus, and testis. The organs in which the sex chromatin was difficult to demonstrate are brain, liver, spleen and blood corpuscles. 2) No significant variation in the appearance rate of the sex chromatin according to fetal age was observed between 4 months and 10 months of the fetal age. The appearance rate of the sex chromatin among the various organs showed no remarkable difference. The average appearance rate of the sex chromatin in the male fetus was from 0.2% to 3.4% (range; 0-8%) and in the female fetus from 84.6% to 96.6% (range;79-100%). 3) In adult males, there was no significant difference in the appearance rate of the sex chromatin among the various organ tissues. The average rate of the sex chromatin was from 0.6% to 5.6% (range; 0-8%). However, in adult female, the difference in the appearance rate of the sex chromatin was to some extent because of relatively lower appearance rate in skin and oral muccsa. That is, the average appearance rate of the sex chromatin in the skin and oral mucosa were 62.0%(range;59-72%) and 52.4%(range; 41-68%) respectively. The appearance rate of the remaining organs showed very similar figures, the average being 84.4-94.4% (range;74-99%). These figures are similar to those of the fetus. 4) Sexual difference in the appearance rate of the sex chromatin in the various organ tissues of both fetus and adults was apparent. 5) Among three types of the sex schromatin the appearance rate in the various organ tissues of the adult and fetus in order of the frequency was marginal type, submarginal type and bipartite type. Bipartite type was seen in every organ tissue of the female while in the male it was seen rarely.

저자는“이 책애서 수많은 결혼 생활을 절개해 해부하고,그것이 실제로 어떻게 지속되는지 알아내며,그 안에 놓인 도전들을 통해 영적 의미와 깊이 그리고 성장을 이끌어낼 것이다.…이 책의 목적은 보다 행복한 결혼 생활로 가는 방법을 가르쳐 주는데 있지 않다.결혼 생활의 도전,기쁨,투쟁 그리고 여러 기념 의식 등을 통해 우리가 어떻게 하나님께 더 가까이 나아갈 수 있고,크리스천의 성품으로 성장할 수 있는지 알아보는데 목적이 있다”고 밝힌다.“결혼하면 약혼 반지와 결혼 반지 그리고 고난의 반지를 얻게 된다.”남편과 아내 모두 자신을 포도주 틀에 넣고 짜야 기쁨과 위로라는 포도주를 얻을 수 있다.결혼은 당신이 나를 사랑하면 나도 당신을 사랑하겠다고 하는 계약이 아니라,남자와 여자가 하나님 사이에서 맺게 되는 일생 동안의 거룩한 언약이다.혼인 서약은 당사자끼리의 계약이 아니라 언약이다.서로 사랑하겠다고 약속하는 것이 아니라 서약하는 것이다.엄밀히 말해,서약이 사람을 지키는 것이지 사람이 서약을 지키는 것이 아니다.결혼을 계약으로 간주하면,배우자의 단점과 잘못과 실수만을 볼 것이며 조금 화가 나도 심하게 분노할 것이다.반면에 결혼을 언약으로 간주하면,배우자의 현재 모습을 보는 것이 아니라 앞으로 변화될 모습을 보며 그의 결점을 사랑으로 덮어줄 것이다.지금이야말로 계약 결혼을 언략 결혼으로 바꿀수 있는 좋은 기회이다.
