김종태,강현구 한국현대문예비평학회 2003 한국문예비평연구 Vol.- No.13

After this treatise grasped the point that a character of the Baekhwa school was idealism, egoism, illuminism, and art for art’s sake, it investigated what appearances that these thoughts had reflected on the Korean modern literature to make Lee Kwang-Soo and Kim Dong-In two pivot objects of study. They, Lee Kwang-Soo and Kim Dong-In met with works and thoughts of the Baekhwa school writers to go to Japan about the time when they played an important role in the Japanese literary world. But they who had quite different characters and thoughts accepted the Baekhwa school through a different logical connection with each other. When He, Lee Kwang-Soo had met with works, he formed an enlightenment consciousness of idealism, and Kim Dong-In egoism and art for art’s sake. The Baekhwa school is the representative writers in the Japanese idealism. They are an important writers from the viewpoint of on the comparative literature of Korea & Japan novel because the Baekhwa school had an effect on two writers who formed the basis of the Korean modern novel. We find out that the Baekhwa school had an enormous effect on the Korean literature if we will consider a relative importance Lee Kwang-Soo and Kim Dong-In have come into possession of the history of Korean novel.

To investigate the prognostic factors for the survival of transplanted kidney in patients with end-stage renal failure, 59 cases of renal transplantation from September 1986 to Feburary 1997 in Chungnam National University Hospital were analyzed retrospectively. The results were as follows: 1)The mean age of recipients was 33.8 years and that of doners was 38.9 years. The male to female ratio of recipients was 2.5:1, and that of donors was 1.03:1 2) Living related donore(LRD) were 79.6% and living non-related donors were 20.3%. The HLA-identical donors(ID) in LRD were 18.7% and HLA-haploidentical donors(HID) were 61.0%. In living non-related donors(LNRD), mean matched HLA-AB antigens were 1.56 and mean matched HLA-DR antigens were 0.56. 3) The average 5-year patient survival fate was 94%, and average 5-year graft survival rate was 70%. The 5-year graft survival fate of HLA-ID was 100%, and those HLA-HID and LNR were 70% and 36% respectively. 4) Total 33 episodes of acute rejection were found in 45.8% of transplanted patients. The number of acute rejection episode did not show significant difference between LRD and LNRD(P > 0.05). There was no significant difference in MLC between two groups(p > 0.05). 5) In comparison between the 18 patients who lost their graft function in 5 years and 17 patients who are maintaining graft function for more than 5 years, MLC was significantly lower in patients with functioning graft than of patients with non-functioning graft (p < 0.05). The number of rejection episode was also lower in patients with functioning graft than that of the patients with non-functioning graft(p < 0.05). However, there were no significant difference in recepient and donor age and history of pre-transplantation donor specific transfusion between two groups. With the results above, we can speculate that adequate donor selection according to good matched HLA typing and low MLC is very important for graft survival in renal transplantation. Prevention and treatment of acute rejection in renal transplantation is also na important factor for graft survival.

배경: 유전성 대사질환의 치료로서 효소 요법 및 유전자 치료가 제한적인 현실에서 동종 조혈모세포이식이 현재로선 가장 중요한 치료가 될 수 있다. 본 연구에서는 단일 기관에서 유전성 대사질환에 대해 동종 조혈모세포이식을 시행한 경험을 보고하고자 하였다. 방법: 삼성서울병원 유전성 대사질환 조혈모세포이식팀에서는 1999년 12월부터 2001년 3월까지 총 6례의 유전성 대사질환을 대상으로 동종 조혈모세포이식을 시행하였다. 대상 질환은 Hunter 증후군 3례, galactosialidosis 1례, 이염성 백질이영양증 1례, 부신백질이영양증 1례였으며 성별 분포는 남아가 5명, 여아가 1명이었으며 연령 분포는 2년 9개월에서 15년 9개월이었다. 5례는 HLA 일치 혈연간 골수이식이었으며 1례는 HLA 불일치 T 림프구 제거 말초혈액 조혈모세포이식이었다. 전처치는 모두 BuCy를 사용하였으며 이식편대숙주반응의 예방에는 cyclosporine을 사용하였다. 이식된 세포는 유핵세포가 4.81×10^(8)(2.40~7.01×10^(8))/kg이었으며 CD34+ 세포는 3.65×10^(6)(0.88~10.72×10^(6))/kg이었다. 결과: 이식 후 조혈기능의 회복은 모두 조기에 달성되었으며(ANC>500: 정중 9.5일, 범위 9~14일; PLT>50K: 정중 32일, 범위 23~34일) 이식과 관련된 합병증은 Gr I의 aGVHD 3례, 국한성의 cGVHD 1례, 경증의 간정맥 폐쇄성 질환이 1례이었다. 모든 환자에서 직간접적으로 이식 후 효소의 생산이 증가함이 확인되었으며 임상적인 호전을 보인 경우가 4례, 질병 진행이 중단된 경우가 1례, 질병이 진행된 경우가 1례이었다. 질병 진행이 중단되었던 1례는 면역억제제 투여 중 수두 감염에 의한 폐출혈로 사망하였다. 결론: 유전성 대사질환에서 동종 조혈모세포이식이 가장 중요한 치료법으로 사용될 수 있고 중추신경계 증상이 나타나기 전, 가능한 조기에 조혈모세포이식을 시행하는 것이 바람직할 것이며 적극적인 지지 요법이 필요하다. 향후 더 많은 임상 경험이 필요하리라 사료된다. Background: Allogeneic hematopoietic stem cell transplantation (HSCT) may be the most important treatment modality to cure a number of genetic metabolic disorders because of the limitation of enzyme replacement or gene therapy. In this study, we report our single center experience about HSCT in several genetic metabolic disorders. Methods: We performed 6 cases of HSCT for genetic metabolic disorders from December 1999 to March 2001. Patients' diagnoses were Hunter syndrome (3), galactosialidosis (1), metachromatic leukodystrophy (1), and adrenoleukodystrophy (1). Stem cell sources were bone marrow from HLA matched sibling donors in 5 patients and mother's peripheral blood stem cells in one patient who did not have HLA matched donors. Busulfan and cyclophosphamide for conditioning, and cyclosporine for the prevention of graft versus host disease were used in all patients. Transplanted total nucleated cell counts were median 4.81×10^(8)(2.40~7.01×10^(8))/kg , and CD34+ cells 3.65×10^(6)(0.88~10.72×10^(6))/kg. Results: All patients achieved early hematologic recovery (median 9.5 days, range 9~14 days for ANC>500/μL; median 32 days, range 23~34 days for PLT>50,000/μL). Transplant-related complications were 3 cases of grade 1 acute GVHD, a case of limited chronic GVHD, and a case of mild hepatic veno-occlusive disease. Enzyme levels were normalized in 4 patients evaluated and there were indirect evidences of enzyme production in the other 2 patients after HSCT. Four of the 6 patients showed symptomatic improvement, 1 patient (galactosialidosis) experienced disease stabilization without progression before he eventually died due to pulmonary hemorrhage, and the other 1 patient deteriorated progressively even after HSCT. Conclusions: Allogeneic HSCT can be done as the only curative treatment in a number of genetic metabolic disorders. It seems desirable to perform HSCT as early as possible before the onset of central nervous system symptoms. More experience and long term follow up is needed to evaluate the efficacy and to monitor the long term transplant-related complications.

This paper proposes an adaptive fuzzy control method with torque observer for position control of BLDC motor. The proposed method is composed of two control inputs, that is, an adaptive fuzzy control input and an auxiliary control input based on the torque observer. The auxiliary control input is introdued to enhance the ability of the control activities, and the performance of the overall system is improved due to its role. A stable adaptive fuzzy control rule is obtained using Lyapunov method. In doing so, we adopt a novel error dynamics related with the output performance, which is entirely different from the usual mechanism only related with the control input performance. An illustrative example is presented to show the effictiveness of the proposed method.

Recently domestic mobile carriers have been engaged in heated battles for survival as the market is now rapidly approaching its maturity phase, and the launch of 30 service combined with the introduction of mobile number portability is dramatically reshaping the market landscape. The mobile carriers may have to create and maintain their competitive advantage based on their core capabilities and differentiated strategies, which will lead continuous survival and profits of the firm. This paper investigated competitiveness factors among mobile carriers, and analyzed the relationships of firm capabilities, competitive strategies and competitive advantage. We found that core capabilities and competitive strategies affecting competitive advantage are different from each carrier. Finally, we discussed strategic implications for carriers to increase their competitiveness.

A control structure to be used for rejecting periodic (or repetitive) disturbances from the output of a system is presented. The objective is to drive the output of the system to the reference input which results in the perfect fallowing. The proposed structure includes a neural-network to identify the inverse dynamics of the system, where the dynamics of the disturbance is grasped. The identification is done at an on-line process. The dynamical back-propagation algorithm is applied to the training of the neural-network. Since the control structure acquires the dynamics of the disturbance by on-line identification. it is possible to generate control signals that reject any disturbance provided that it does not diverge.

This treatise investigated the deathly consciousness appeared on Park Jae-Sam's poem to divide in two aspects. The two aspects is not divided but is composed of complement. He, Park Jae-Sam did not think to separate a matter of life and death. He was accepted in a means to disregard the peril of one's life without denial or fear against an immanent narration of death in a human life always through a consciousness of monism on life and death. Especially he was accepted a deathly imagery as some- to be of aesthetics, as well as death which is not ugly or torturous. Furthermore, it was the process of life most beautiful and pure. When it came to the climax of death, he considered that the life would arrive at a perfect condition of aesthetics. He, Park Jae-Sam who kept his attitude to accept death enhanced the life will through a humble cognition of death. And he, who was able to accept death could live in his life more pious, humble, and beautiful. He was suffering hypertension from the mid of 196Os, and he had to labored under his disease of chronic renal failure symptom from 1980s. He published his poetries of no less than 15 volumes in such conditions. His will to a creation enabled him to overcome the fight with the demon of ill health. This life has a great thread of connection with his literary cognition to death.

The determination of peripheral nerve conduction velocity is and important part to electrodiagnosis. Its value as neurophysiologic investigative procedure has been known for many years but normal value of median and ulnar motor nerve was poorly reported in Korea. To evaluate of median and ulnar motor nerve terminal latency, amplitude of CMAP(compound muscle action potential), conduction velocity and F-wave latency for obtain clinically useful reference value. 71 normal volunteers(age,19-65 years;142 hands) examined who has no history of peripheral neuropathy, diabetic mellitus, chronic renal failure, endocrine disorders, anti-cancer medicine, anti-tubercle medicine, alcoholism, trauma, radiculopathy. Nicolet Viking Ⅱ was use for detected terminal latency, amplitude of CMAP, conduction velocity and F-wave latency of median and ulnar motor nerve. Data analysis was performed using SPSS. Descriptive analysis was used for obtain mean and standard deviation, independent t-test was used to compare between Rt and Lt side also compare between different in genders. The results are summarized as follows: 1. Median motor nerve terminal latency was right 3.00ms, left 2.99ms and there was no significantly difference between right and left side and genders. 2. Median motor nerve amplitude of CMAP was right 17.26mV, left 17.50mV and there was no significantly differences between right and left side and genders. 3. Median motor nerve conduction velocity was right 57.89m/sec, left 58.03m/sec and there was no significantly difference between right and left side and genders. 4. Median motor nerve F-wave latency was right 25.74ms, left 25.59ms and there was significantly differences between genders. 5. Ulnar motor nerve terminal latency was right 2.38ms, left 2.45ms and there was significantly differences between right and left side. 6.
