The French Lieutenant's Woman : 자유로운 글쓰기 과정과 실존적 인식
정길화 신한영미어문학회 1997 새한영어영문학 Vol.38 No.-
Fowles assumes dualistic narrative strategy in this novel. First, he uses the framework of realistic novel and intervenes consistently in the text as omniscient narrator or author. Second, Fowles reveals apparently in the text that his narrative is a fiction. This strategy has the effect of demolishing the framework of traditional novels and of destroying the modernist' 'illusion' in which they insist on the objective technique. In The French Lieutenant's Woman, Fowles illuminates a new direction which modern novels should take, using a variety of themes and technique. By introducing 'creative anachronism' for considering freely the years of the 1860's and the 1960's, Fowles deals with human existential condition and the freedom of modern artists who should strive for their existential choice. In this way, Fowles combines the traditional realistic mode of writing and the experimental one, and he tries to solve his aesthetic problems which are related with his theme and technique, as well. Fowles assumes his dualistic attitude by describing his desire and 'anxiety' for freedom. This is an aestheic problem which can be related not only to the author but also to the characters (especially Charles and Sarah) and the modern readers. With the introduction of the technigue of open ending, Fowles endows all of them with freedom. In The French Lieutenant's Woman, there exist an existentialist awareness and a desperate spirit which provide the process of the character's life, of author's writing, and of reader's response with their meaning. Metafictional elements which can be related to the process of creative writing itself and which show, as its consequence, 'self-conscious, aesthetic interest' are not just fictitious, symbolic, and labyrinthine in the pleasure of language game. The effect comes out of concrete, living realities which are equivalent to an existentialist awareness and suffering.
1100 및 6061 알루미늄 합금에 있어서 Strain Rate가 流動應力에 미치는 영향
鄭潾相,李鍾武,芮吉村 慶北大學校 産業開發硏究所 1976 硏究報告 Vol.4 No.-
The effect of the strain rate on the flow stress and the strain rate sensitivity were investigated for 1100 and 6061 aluminum alloy heat-treated in the different ways. The flow stress increment increased with the increase of the strain rate over the range of 0.01∼1.0 min_-1 in the furnace cooled 1100 aluminum specimens, while it was aproximately constant in the water quenched ones. When the ratio of the strain variation increased up to a hundred times, the value of the strain rate sensitivity decreased for the water quenched 1100 aluminum specimens. And the effect of the strain rate was negligible in either case of the furnace cooled 1100 aluminum and 6061T_6 heat treated alloy. The load carring ability rised along with the extent of decrease in the strain rate over the range of 0.01∼1.0 min^-1 for the water quenched 6061 aluminum alloy.

An experimental investigation was conducted to investigate the strength and deformation capacity of Wide Flange Steel Encased Reinforced Concrete(SRC) Columns subjected to constant axial compression and cyclic lateral loading conditions. Six one-third scale specimens were tested, each consisting of a structural steel size encased in reinforced concrete. The parameters studied in the test program included the effects of B/t ratios of encased steel(=13, 18, 23), ratios of axial force(=1/3, 1/6). As a result, capacity prediction based on superimposing the moment-axial-load interaction surfaces of the steel shape and reinforced concrete produced good results; the average of the experimental-to-predicted capacity ratio being equal to 0.99∼1.20. The observed hysteretic behavior of the test specimens indicated that adequated ductility can be achieved and the concrete core must be inhibited to buckling of wide flange.

In this study basic equations for the pulsatile laminar flow in a circular rigid pipe containing a slightly compressible fluid are derived and analytical solutions for the distributions of wave propagation factor K, cross-sectional mean velocity u_(m) and pressure P are schematically developed and confirmed experimentally. The pulsatile flow with 0 ≤ f ≤ 48Hz and 0 ≤ Re ≤ 2500 generated by summing the oscillatory flow made by ball valve into steady one. The wave form of pulsatile flow is described as a longitudinal wave and particle velocities measured experimentally are group velocities of the wave packet which are always smaller than phase velocities which are approximate to the sonic velocity C when the radial dispersion and wall friction are negligible. Therefore wave number is approximated to k = ω/c for high angular velocity region. The axial pressures and centerline velocities were measured by strain-gage type pressure transducers and Pito-static tubes, respectively. The cross-sectional mean velocities calculated from centerline velocities with the parabolic distributions of the laminar flow and confirmed by using the ultrasonic flowmeter. We knew that axial distributions of oscillatory velocity and pressure coincide with thoeretical and depend on the Reynolds number and angular velocity.

The purpose of this study was to investigate the factors related to environment-oriented consciousness and Behavior in family life. A questionnaire was prepared with 57 questions each question used the 5 scale Likert type. The questionnaire was administered to 327 housewives who had 6-24 year old children and lived in Seoul and Kimpo. The contents of the questionnaire consisted of the questions to measure acknowledgement of environment problems, consciousness of environmental pollution and recourses, environment-oriented behavior when buying, using, and disposing the living goods. The findings were as follows: 1) The level of environment-oriented consciousness and behavior of those housewives was high, but the scores of questions containing individual sacrifice and effort were lower than the others. 2) Environment-oriented consciousness and environment-oriented behavior were significantly correlated. According to level of those two factors, three groups(high, medium, low) were divided by cluster analysis. The effect of socio-economic factors (education level of housewives, number of children, employment state of housewives, living expenses) to environment-oriented consciousness and behavior was very weak.

Background: Small cell carcinomas (SCC) are most commonly seen in the lung, approximately 2.5-4% of all SCC occur in extrapulmonary sites. This study aimed to review the clinical features, therapy and natural course of patients with extrapulmonary small cell carcinoma (EPSCC) in single-institution series. Methods: We retrospectively reviewed the medical records of patients with SCC between December 2002 and November 2005. Study eligibility required that patients had pathologically proven SCC in sites other than lung with normal radiological findings of the chest and normal sputum cytology or negative bronchoscopic findings. Result: Eight patients with EPSCC were identified and their primary sites were various such as esophagus (4 cases), kidney (1 case), thymus (1 case), stomach (1 case) and unknown primary supraclavicular lymph node (1 case). The 4 patients were classified as limited disease (LD) and 2 patients were as extended disease (ED) at initial staging work-up. But 2 patients were undetermined. The 3 patients with EPSCC of LD were treated with operation and adjuvant chemotherapy or chemotherapy and radiotherapy and one received only supportive care. They showed favorable clinical courses with a median overall survival of 23 months. EPSCC of ED and undetermined group received only supportive care. They had aggressive clinical courses with a median overall survival of 3 months, Conclusions: EPSCC was identified in various sites with the most common primary site being the esophagus, It was predominantly occurred in old male patients and associated with smoking like as SCC of the lung. Since EPSCC is a relalively rare disease that mimics SCC of the lung in its response to treatment and survival pattern, it would appear advisable to follow similar treatment guidelines. Although recurrence within short terms was observed, a significant survival benefit was obtained in EPSCC of LD received treatment (chemotherapy, operation and radiation therapy). Thus, EPSCC is usually a fatal disease with meidan overall survival of 18 months. 연구배경: 소세포암의 가장 흔한 발생부위는 폐이며, 폐외소세포암은 전체 소세포암의 2.5~4%를 차지하는 매우 드문질환이다. 본 연구의 목적은 단일 기관에서 진단된 폐외소세포암의 임상적 특징, 치료와 자연경과를 보고하고자 하였다. 방법: 조선대학교부속병원에서 2002년 12월 부터 2005년 11월 사이에 소세포암으로 진단된 66명의 의무기록을 검토하였다. 폐외소세포암은 흉부 단순 몇 전산화단층 촬영, 객담세포 검사, 기관지경 검사에서 폐병번이 없으면서 폐와 병변의 조직학적 생검에서 소세포암으로 증명된 경우로 하였으며, 총 8명이였다. 결과: 본 연구에서 식도가 전체 폐외소세포 암 환자의 50%(4례)로 가장 많은 원발병소를 보였으며 그 외 흉선, 신장, 위가 1례씩 있었으며 쇄곧상부 림프절에서 소세포암이 발견되었으나 원발 병소를 발견 못한 경우가 1례 관찰되었다. 4명의 환자는 제한 병기를 보였으며 2명은 광범위 병기를 보였지만 나머지 2명은 위내시경으로 식도에서 소세포암이 조직학적으로 진단되었으나 보전적 치료만을 받길 원하여 병기결정을 위한 검사는 시행할 수 없었다. 제한 병기의 폐외소세포암 환자는 4명이었다. 2명은 수술적 절제후 보조항암화학요법을 받았으며, 1명은 항암화학요법후 방사션치료를 받았고, 나머지 한명은 보전적 치료만 시행하였다. 제한 병기의 폐외소세포암 환자틀은 양호한 임상 경과를 보였으며 중앙 생존기간은 23개월이었다. 하지만 광범위 병기의 폐외소세포암 환자와 병기를 분류할 수 없던 환자에 대해서는 항암화학요법 등의 적극적 치료는 시행하지 않고 보존적 치료만 시행하였다. 그들의 임상경과는 빠르게 악화되었으며 중앙 생존 기간은 3개월이었다. 결론: 본 연구에서 폐외소세포암은 다양한 장기에서 발견될 수 있으나 가장 흔한 곳은 식도였다. 소세포폐암과 유사하게 고령, 남성 및 흡연과 관련을 보였었다. 제한 병기에서 국소 치료, 항암화학요법은 생존기간의 연장을 보였으나 쉽게 다른 장기로 전이가 되거나 재발하는 매우 치명적인 질환임을 확인할 수 있었다. 전체 중앙 생존기간은 18개월 이었고 항암 화학요법등의 치료를 받은 군이 보존적 치료를 받은 군에 비해 의미있는 생존기간 (p=0.040)의 연장을 보였다. 본 연구는 단일기관의 상대적으로 적은 수의 소규모 연구이지만 폐외소세포암의 제한 병기에서 국소치료 및 항암화학요법은 생존기간의 연장을 보였고 쉽게 다른 장기로 전이가 되거나 재발하는 매우 치명적인 질환임을 확인 할 수 있었다.

Evans syndrome is defined as a simultaneous or sequential occurrence of autoimmune hemolytic anemia and autoimmune thrombocytopenia. Autoimmune hemolytic anemia (AIHA) is usually induced by IgG warm autoantibody or cold-active IgM antibodies reacting specifically with antigens associated with a patient's RBC. AIHA is a fairly uncommon disorder, with estimates of the incidence at 1 to 3 cases per 100,000 per year. Mixed-type AIHA is a relatively uncommon form of AIHA, with studies noting the incidence of 7-8% among cases of AIHA. We experienced a patient, 46-year-old woman who was diagnosed having a very rare clinical presentation of mixed warm and cold antibody mediated Evans syndrome. She was treated with corticosteroid therapy only and has been maintaining a complete response for 15 weeks. 저자들은 혼합형의 자가면역성 용혈성 빈혈과 자가면역성 혈소판 감소증이 동시에 발생한 혼합형 Evans 증후군으로 진단하고 스테로이드 요법 후 혈액학적으로 회복된 상태로 15주가 지난 현재 steroid 5 mg/일 까지 감량한 상태에서 추적 관찰 치료중인 46세 여자 환자를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

The present study was undertaken to determine the optimum current range which can elicit an osteogenic response by observing the changes in osteogenesis induced when varying amount of constant direct current was applied to rat(Sprague-Dawley strain) femur. In oder to carry out this experiment,18 rats weighing about 200gm were selected and divided into 2 groups,one control group consisting of 3 rats and one experimental group consisting of 15 rats.The control group was received the dummy electrodes that were not connected to the power supply pack.The experimental group was subdivided into 3 groups according to the amount of constant direct current applied(5-15㎂,20-3㎂,and 40-50㎂). Under the general anesthesia with intravenous injection of thiopental sodium,all surgery was performed with aseptic precautions, and each animal was administered soluble cephradine by intramuscular injection at the end of the surgical procedure. A 0.010 inch stainless steel wire covered with polyethylene tube was tied at the right mid femoral portion of the rat, and this wire,serving as a cathode,was connected to the Constant Current Sink. Anode was implanted subcutaneously over the dorsum at the cross section area where the vertebral column and a line connecting the both iliac crests, and then connected to the Sink. All animals sacrificed at 7 days after application of electrical stimulation. 2 sites near the cathode were prepared for histologic findings including LM and SEM. Based on the present study the followeing conclusions can be made: 1.In both control experimental group,new bone formed by a process of intramembranous bone formation was appeared in the periosteal and endosteal surface of the bone at the vicinity of the cathode,and the area of bone resorption was found at the margin of the newly formed bone,and bone resorption was occurred between newly formed bone and old bone at the endosteal surface. 2.According to the increased amount of the direct current applied, a new bone formation was significantly occurred in a more rough and irregular pattern. 3.The optimum current range seemed to be in 5-30μA and the current in 40-50μA range caused tissue degeneration and severe bone resorption. 4.In the newly formed bone on the periosteal surface,the new bone trabeculae were formed at a more perpendicular direction to the long axis of the femur according to the increased amount of the direct current.

This study was conducted to evaluate the effects of microbial inoculation on sewage sludge composting. The number and species of microorganisms in sewage sludge sampled on February were higher than those sampled on August. The composting of sewage sludge is inhibited by the polyacrylamide cation, which was used as a coagulant and known to repress the growth of microorganisms. The growth of all microorganisms was inhibited by the addition of the polyacrylamide cation at a concentration of more than 0.8%. The species and viable counts of microorganisms were observed to increase during composting sewage sludge by inoculation of the effective microorganisms and addition of the pine tree sawdust as a bulking agent, compared with those without inoculation. A variety of organisms in compost(sewage sludge plus sawdust) were observed after composting for 30 days, such as Fragilaria sp., Proales sp., Vorticella sp., Schizothrix sp., Anabaena sp., Zoothaminium sp., Epstylis sp., Arcella sp., Balantidium sp., Actinophrys sp., Synedra sp., Euglypha sp., Ulothrix sp., Anacystis sp., and Clostium sp.
