The purpose of this study is to examine in details the effects of the constructive instruction on the acquisition of scientific conceptions and the problem solving of Science based on ICT (Information and Communication Technology). In this study, An examination tool developed for a previous learning concept was applied to instructional model by a constructivism to students, and by grasping a previous learning concept and using ICT. An way of the improvement about acquisition of scientific conceptions and problem solving of subject was inspected, the rate of a correct answer, the decrease rate of misconception, and the achievement rate of a periodical examination were compared. The result of such enforcement was as follows; The motivational induction for learning, the interesting rate, and the rate of a correct answer in an experimental group showed highly. The result of a examination between an experimental group and a comparative group showed similarly. The rate of accomplishment also showed highly in an experimental group. Accordingly, the constructive instruction using ICT proved to be fit for seventh educational course as a student-centered course. The change of recompositional course for knowledge from a previous learning concept to a new one showed clearly.

大田地方에서 製造된 Cement Brick(벽돌)의 强度에 對한 考察…[Ⅰ]

宋寅春,李正熙 大田工業高等專門學校 1968 論文集 Vol.3 No.-

시멘트벽돌(Cement Brick)은 組積式構造에 使用되는 材料로써 諸 建築物에 關連되어 있는 主要한 建築材料이다. 이런점으로 보아서 Cement Brick은 簡單하고 容易한것 같으나 여러가지 複雜하고 아직까지 解決되지 못한 점들이 많이 남아 있는 것이다. 이러한 점을 생각해서 이 地方에서 製造되고 있는 Cement 벽돌을 20餘個~場所에서 蒐集하여 KS F_4004(한국감정공업규격)에 어느만큼 到達하고있는가를 土台로 삼아 壓縮强度, 吸水率, 形狀과 規格 等을 試驗하고 分析 檢討하고저한다. Now that the cement bricks play a great part in modern construction, brick makers are requested to make the ones proper for industrial standard, so that they can help develop the national construction project, a second five-year development plan. I have collected the cement bricks made by the twenty different makers in Taejon area, and some suggestions are made according to the data obtained through my experiment.

Nowadays many products using nano-technology have been released and nano-technology would be more prospected in all kinds of industries especially cosmetic manufacturing and ingredient fields. In cosmetics, the saturated lecithin, one of the main surfactants to make liposome, has been used for its stability but it has been substituting by unsaturated lecithin which has excellent skin affinity and penetration. So we studied to develop nano-liposome below 50㎚ with unsaturated lecithin. To make stable nano-liposome, many factors including solvent like propylene glycol, pH balance, homogenizing pressure and liposome stabilizer like surfactant are important especially stearate series surfactants have positive effect in liposome size and long term stability. But in liposome with saturated lecithin, surfactant has negative effect and appropriate amount of oil should be used to be stable. So we could conclude that unsaturated lecithin is suitable than saturated lecithin to make nano-liposome.

We analysed 404 patients with primary lung carcinoma who were treated at Soonchunhyang University Hospital from July, 1985 to september, 1993 in order to investigate the survival rate and epidemiolgical properties of primary lung cancer. They were 330 males and 74 females. The most prevalent decade was seventh. In terms of cell type, the squamous cell was 225 patients (55%), and adenocarcinoma, small cell, mixed type was 21%, 19%, 4%, respectively. Among non-small cell lung carcinoma, stage Ⅲa was the most prevalent one(92%). In case of small cell carcinoma, the limited stage was 64%. The 12-, 24-, 36- month survival rate of total patients was 57%, 31%, 22%, respectivley and median sruvival time was 15 months. The 36-month survival rate tended to be longer in non-small cell lung carcinoma than that of small cell lung cancer, but there was no difference between two groups, statistically. In non-small cell carcinoma, The 36-month survival rate and meidan survival time were longer in the stage Ⅰ and Ⅱ than those of Ⅲa, Ⅲb, Ⅳ (80% versus 38%, 22%, 0%, p<0.05). According to involvement of lymph node, the 36-month survival rate was longer in NO and N1 than those of N2, N3 (61.9%, 48.7% versus 17.7%, 17.3%, p<0.05). In small cell carcinoma, The 36-month survival rate and median survival rate were higher and longer in limited stage than those of extensive stage(16.1% and 13 month vs 10% and 8 month, p<0.05). In conclusion, we report here the incidence of primary lung carcinoma and the survival rate of paients with primary lung carcinoma who were treated in Soonchunhyang University Hospital.

Histiocytic medullary reticulosis (HMR) is a malignant noeplastic process, with tumor cells belonging to the histiomonocytic line, and originally described by Scott and Robb-Smith in 1939 characterized by its acute onset, progression to death within a few months and its clinical features are fever, lymphadenopathy, hepatosplenomegaly, jaundice, and purpura common laboratory findings are characterized by severe anemia, leukopenia, thrombocytopenia and histologically by systemic progressive invasion of morphologically atypical histiocytes or of their precursor. 61 and 37-year-old males were admitted with camplaints of high fever and chilling sensation and were treated by cyclophosphamide, vincristine, prednison and antiobiotics, but patients all died 17 and 14 days after admission due to probably sepsis and respiratory failure.

저자들은 척수압박으로 하지마비를 보인 환자에서 수술 후에 급성 백혈병에 동반된 과립구성 육종으로 진단된 환자 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Granulocytic sarcoma(GS) is an uncommon tumor composed of immature cells of the granulocytic series. Most case of GS occur in the course of acute leukemia and the blast crisis of chronic leukemia, Rarely, however, it may present before leukemia becomes clinically apparent. It may also occur in patients with myeloproliferative disoders. GS has been reported that it occurs in 3% to 9% of patients with acute myelogenous leukemia(AML) and the incidence of GS is reported to be higher in patients with t(8;21). GS occurs relatively commonly in africa and has been reported to affect 10-25% of black children presenting with AML. This is very rare case of granulocytic sarcoma with AML(FAB M5) presented with spinal cord compression which was supported by decompression laminectomy.

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.

Tsutsugamushi disease is an acute febrile illness caused by Orientie. tsutsugsmushi. It is characterized by fever, myalgia, lymphadenopathy, and rash. And it can be easily diagnosed by characteristic eschar and serologic testing. Nearly all of the patients with tsutsugamushi disease improve with antibiotics such as doxycycline. However, the fatality rate of untreated cases is seven to ten percent. Splenic infarction is not common disease which is caused by occlusion of the main splenic artery or any of its branches. It is mainly caused by emboli that arise from cardiovascular disease, but sometimes by regional thrombosis associated with leukemia, myeloproliferative disorder, sickle cell anemia, pancreatitis, splenic torsion and septicemia. We experienced one case of tsutsugamushi disease with splenic infarction, which was improved after doxycycline treatment finished.
