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.

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.

The French Lieutenant's Woman : 자유로운 글쓰기 과정과 실존적 인식

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.

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.

The samples of blood from 140 Holstein cows in Chonnam area were examined and analysed on the basis of age. The results were as follows: 1. The mean values of erythrocyte counts and hemoglobin contents were low in comparison with other reported values. There were no significant differences of the values between age groups. 2. Total and differential leukocyte counts in percentage were same as other reported values. The total white cell counts decreased with age, while with the eosinophil counts the opposite was the case. 3. Mean absolute values in differential leukocyte counts were same as other values previously reported. 4. The observed neutrophil-lymphocyte ratio was 0.45, which was normal value. 5. The direct and indirect eosinophil counts were made on the same samples. The direct method gave higher estimated numbers of eosinophils, and there were no significant differences between the eosinophil numbers estimated by the two methods except in the age group of 3-year.

It was argued in this paper that materialism was an important and useful consumer behavior construct. Despite its obvious relevance to consumer behavior, it had been neglected by marketing researchers, Recently, a number studies on materialism have appeared in the consumer behavior literature. The works have been almost solely done by Belk. Other recent consumer researchers who have written in this area include Fidman, Richins, Fournier, Dawson, Bilkent, and Rochberg-Halton. The paper defined materiaBism as "a general belief that worldly possessions and/or consumption are/is the route to personal happiness and/or satisfaction in life". This definition underscored the linking of worldly possessions and consumption with personal happiness and satisfaction in life. Materialism is a multi-dimensinal concept which includes not only traits, but attitudial, behavioral, and value conponents. This paper reviwed some of the exiting knowledge about materialism and concluded that the construct was appropriately measured as a valud within the constellation of a personal or curltureal value system. Materialism would manifest it self in the way consumer behavior in the market place. The high materialism consumer would behave differently in terms of consumption behavior and life style when compared to the low materialism consumer. The paper should motivate researchers to further explore the impact of materialism on consumer behavior activities and life style. Knowing society's general attitud toward materialism, and Knowing the demographic groups that tend to be more materialistic, marketers can devise appropriate maketing strategy in products, price, place and promotion.

The purpose of the present experiment is to determine the suitability of rat model for the experimental staphylococcal mastitis. A strain of Staphylococcus aureus isolated from a case of bovine mastitis was inoculated through the teat canal into the mammary gland of lactating rats. The rats were removed from their offspring or left with them to allow suckling, as required by the experimental design. 1. No generalized reactions or symptoms of mastitis were observed in all rats. 2. At necropsy, affected glands showed discoloration; abscesses up to 2.5mm in diameter were observed in one group of "lactating" rats inoculated with 10x10?? colony-forming units of staphylococcus. 3. Histologically fat droplets retained within the alveoli were prominent in many sections. Epithelial hyperplasia and slight interalveolar fibrosis were also noted. 4. The number of bacteria recovered from the inoculated mammary gland was smaller than that of bacteria inoculated. The bacteria were more readily recoverable from the mammary glands of "non-lactating" rats than from "lactating" rats. 5. To determine a suitable rat model for the experimental staphylococcal mastitis, further studies should be carried out, using different strains of Staphylococcus aureus and also different strains of rats.

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.
