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.

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.

Centerline macrosegregation is one of the most significant problems in continuous casting on stainless steel slabs. Numerical model have been developed in order to decrease centerline macrosegregation during continuous casting of STS 420J2 stainless steel slab. Extra cooling zone and extra cooling water quantity are determined by iterative coupled analysis of heat transfer and segregation. Segregation ratio is decreased by the intensive cooling at the extra cooling zone above the solid fraction of the slab center 0.7, so called thermal soft reduction (TSR). The experimental results show good agreements with numerical results.

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.

Ultrasonic testing of a reinforced concrete member by means of the ultrasonic testing apparatus is affected by the steel bar embedded in concrete. A test location avoid the zone of steel effect when selecting test location in reinforced concrete member. But if it is impossible, it is necessary to make a correction to the measured value to provide an estimate of the velocity of the pulse in the plain concrete. The purpose of this study is to analyze the effect of steel bar on ultrasonic pulse velocity and the evaluate optimum correction formular by means of comparison between pulse velocity in concrete and effective pulse velocity according to steel bar diameters. Concrete mixes having water cement ratio of 0.4 and 0.6 by weight and slump values of 18㎝ in fresh concrete were used to make 20×30×60㎝ cubes for pulse velocity in concrete and effective pulse velocity. The diameters of the plain bars were 6, 9, 12, 19, 25, 32, 38 and 50㎜.

Effect of radix puerariae on blood alcohol concentration and on alcohol effect in alcoholic patients was studied. The subjects were 57 hospitalized male alcoholics recovered from acute intoxication and withdrawal symptoms. They were divided into two groups of 29 subjects of experimental group and 28 control group. The experimental group was adminitrered with 10g/day of powder of radix puerarize and the control group with mixture of 4g/day of radix glycyrrhizae and 6g/day of flour for 4 weeks, respectively. Before and after treatment of the drugs, blood alcohol concentration, vital signs, and mania rating scale were measured at -5, 10, 30, 60, 90 and 120 minutes after administration of 25% alcohol at a dose of 6ml/kg b.w.p.o. The results were as follows: 1) Blood alcohol concentration was not changed by four weeks of radix puerariae treatment and no difference in the blood alcohol concentration was noted between the radix puerariae and the control groups. 2) Radix puerariae significantly lowered systolic blood pressures at 10, 30, 60 and 90 minutes after alcohol intake and diastolic blood pressures at 10, 30, 60, 90 and 120 minutes after alcohol intake as compared to the corresponding pre-treatment levels. Moreover, before radix puerariae treatment, alcohol-induced elevation of systolic blood pressure was significant at 10 minutes after alcohol intake and that of diastolic blood pressure was significant at 10, 30 and 60 minutes after alcohol intake. But after radix puerariae treatment, such elevation was abolished. 3) Radix puerariae reduced significantly levels of motor activity at 60 and 90 minutes after alcochol intake and levels of voice at 10, 30, 60 and 90 minutes after alcohol intake as compared to the respective pre-treatment levels. Alcohol-induced enhancement of motor activity was significantly increased from 10 minutes after alcohol intake before radix puerariae treatment. But after the drug treatment, it was significantly increased from 60 minutes after alcohol intake. Thus radix puerariae delayed the development of alcohol-induced enhancement of motor activity. 4) No significant differences were noted in the levels of anxiety and depression between the index group and the control, either before or after respective drug treatment. 5) Food intake was not changed during the experimental period in both groups.

Rural of Koreas has rapidly changed through the process of industrialization and urbanization. During past 30 years, development differences between urban and rural, metroplitan area and area derived from a highly economic growth, bring about dual specialization that deepens overpopulation and sparsity. Therefore, with a new concern about rural, necessity of rural development policy that developes a settlement and life area for settlement for ensuing stablized settlement and living activity of rural people, has been drived step by step. For rural welfare establishment that is settled and good hereafter, this study aims at attempting a theoretical approach about the way of development for rural settlement as a new rural development strategy through examination of today's rural reality, under assumption that rural people must be able to obtain stable jobs and to be pleasant without leaving rural area, and rural settlement to be able to enjoy urban advantages must be realized. Therefore, items that must be obtained basically rural area to be a human settlement space are equipment connected with a dwelling house, production, consumption, job relaxation, infrastructure connected with transportation or communication network and environment. By the way, the best function of a human settlement space makes a basic pleasant settlement area to be in the middle of that. Then rationalization of land use must be realized as being a best condition for human life around space of a dewelling house. Besides, spacial accessibility about all equipment of inhabitants must be easy. That is, economic distance, social distance and cultural distance as well as spacial distance must be included. Also, those spacial functions must be realized on a basis of suitable enironment for a human settlement life. At the same tiem, the upper area must be connected with the lower area as the system of spacial settlement in settlement space. But truely, as rural people can't satisfy with services of the surrounding rural areas, they desire better city or metroplitan. The these problems bring about inequality between urban and rural. Therefore, here are urgent reasons that must be done rearing of rural central town and rural integrated development of unit area. So, these dys, to correct maldistribution of land use and inequality of settlement space that Korean society faces on, new strategies of rural integrated development for lift area for settlement than gives the meaning. That rural areas become like a place for human settlement life will be able to be chosen in the view of humanism. The say of thinking of rural residents(Jukans-myun, Anseong-gun, Kyeonggi-do) was surveyed in order to develop new rural settlement planning. From the data collected in this survey, rural life-style, view on traditional rural life, agriculture, farming, agri-policy, social attitude, and degree of satifaction of rural life, etc, were analyzed. Firstly, most of rural residents interviewed in this survey have the opinion of not leaving their home village if living conditions improved to a reasonable level in the near future. In decision-making process of village affairs, they want to participate actively and equally. Secondly, in spite of their acceptance of agriculture as a vital sector destined to national security, most of them think that framing should be little of promise. Thirdly, they have the negative attitude to urban-oriented social valued and also to the agricultural policy, while seeking consolation through human and traditional viewing of rural life style. Therefore, in the development of new rural settlement model, idea-making should be directed to the betterment of communal value of village life, stability of rural economy, rationalization of rural life style and enhancement of rural-type happiness.
