      • HSC 기둥의 내진성능에 대한 횡보강근의 효과

        한병찬,황선경,성수용,정수영 충남대학교 산업기술연구소 2000 산업기술연구논문집 Vol.15 No.1

        In seismic-resistant design of buildings of ductile frame, the possibility of formation of plastic hinge at column end demands sufficient member ductility. The paper summarizes results of an experimental study of reinforced concrete columns with high-strength materials and subjected to simulated seismic loadings. The experimental program consisted of 6, approximately one-third-scale, rectilinearly confined, high-strength reinforced concrete columns with concrete compressive strengths of approximately 700kgf/cm2. The primary variables of the testing program were the volumetric ratio, spacing, and configuration of transverse reinforcement. Experimental results indicate as follows : 1.There is no expectation of improved effectiveness of deformability by the types of transverse reinforcement when using high yielding strength transverse reinforcement. 2.When using high yielding strength transverse reinforcement, it is possible to widen the spacing that are designed based on seismic provision of ACI 318-89 and get an appropriate deformability as well. 3.The significant parameter to determine the deformability is the spacing of transverse reinforcement in the HSC columns.

      • 혼합형 자가면역성용혈성빈혈과 동반된 Evans 증후군 1례

        선길홍,윤찬영,박상곤,박경희,우정주,한경택,김진화,김영훈,정춘해,박치영 朝鮮大學校 附設 醫學硏究所 2005 The Medical Journal of Chosun University Vol.30 No.2

        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.

        A strengthening technique for reinforced concrete beams using external unbonded reinforcement offers advantages in speed and simplicity of installation over other, established, strengthening techniques. The purpose of this paper is to investigate the capabilities of a new retrofitting technique, namely external prestressing(Bow), for flexural strengthening of beams. The paper provides a general description of structural behavior of beams strengthened using the technique. Results of 2 physical tests on strengthened reinforced concrete continuous beams are reported and compared. It is shown that the technique can provide greater strength enhancement to lightly reinforced sections and that provision of deflectors enhances efficiency.

        Analysis of KAP1 expression patterns and human endogenous retrovirus Env proteins in ovarian cancer

        Kyung‑Yoon Jeon,Eun‑Ji Ko,Young Lim Oh,Hongbae Kim,Wan Kyu Eo,김아리,Han Gyu Sun,Meesun Ock,Ki Hyung Kim,Hee‑Jae Cha 한국유전학회 2020 Genes & Genomics Vol.42 No.10

        Background Human endogenous retroviruses (HERVs) constitute around 8% of the human genome and have important roles in human health and disease, including cancers. Previous studies showed that HERV envelope (Env) proteins are highly expressed in cancer tissues and co-related with cancer progression. KAP1 has been reported to play a key role in regulating retrotransposons, including HERV-K, through epigenetic silencing. Objective The relationship between KAP-1 and HERV Envs expressions was analyzed only in tumor cell lines and has not yet been studied in cancer tissues. In this study, we analyzed the expression patterns and relationship between KAP1 and HERV Env proteins in ovarian cancer tissues. Method The expression patterns of KAP-1 and HERV Env proteins, including HERV-K and HERV-R, were analyzed in ovarian cancer tissue microarrays that contained 80 surgical specimens, including normal ovary and malignant ovarian cancers. Results The expression of HERV-R Env and KAP1 proteins is signifcantly higher in ovarian cancer compared with normal ovary tissues. However, the expression of HERV-K Env did not change signifcantly in cancer tissues. The expression patterns of HERV-K Env and HERV-R Env signifcantly increased in early stages of cancer and KAP1 expression was higher in certain stage and types of cancers. However, the expression of HERV-K Env, HERV-R Env, and KAP1 did not change in diferent age groups. The correlation between the expression of KAP1 and HERV-Env, including HERV-K and HERV-R, was not signifcantly correlated. Conclusions The results of this study showed that there was no signifcant correlation between the expression of KAP1 and HERV Env proteins in ovarian cancer tissues, unlike studies with cell lines in vitro. These results suggest that the actual expression of HERV Env proteins in ovarian cancer tissues may be regulated through various complex factors as well as KAP1.

        In this paper, we present a case study for developing a crime prediction model in Korea. This model aims to predict regions with high crime rates compared with other regions. To develop the prediction model, we first selected critical variables related to crime occurrence. Second, we collected data for the selected variables some of which were provided by the city hall of Kyung-gi province in Korea. Lastly, we determined relative weights for the selected variables and completed the prediction model by aggregating the selected variables throughweighted summation. Regions with high crime rates were predicted based on the prediction model in this case study.

        This study has been attempted to be helpful for the back rehabilitation of Korean workers by analyzing the general, occupational, social aspects of low back pain and to identify possible risk factors for back pain in White and Blue collar workers. The primary data collected from 339 workers in Kyungnam by means of a questionnaire with random which was distributed from January 10 to 18, 2001. For the test of statistical significance, chisquare analysis was used to compare the back pain characteristics between the two groups. The results were as follows: 1.The incidence of low back pain in all workers studied was 81.1 %. The incidence of Blue collar with low back pain(88.2%) was higher than that of White collars(74.1%) (p<0.01) 2.With regard to the relationship of back pain to the occupational characteristics, statistically significant differences were observed between workers with and without back pain concerning the job factors on work-time, mental stress, work posture, trunk rotation, weight lifting, vibration, and heavy noise(p <0.05). 3.With regard to the relationship of back pain to the social characteristics, there were no differences with respect to traffic time. However, significant differences were showed between no pain and pain groups for the using bed, sleeping posture, walking amount, body type, health state, and physical exercise(p<0.05). 4.The comparative analysis of back pain related to work factors showed significant differences with respect to mental stress, work posture, trunk rotation in White collar group(p<0.05); and mental stress, trunk rotation, work posture, monotonus repetitive work, weight lifting, exposure to vibration in blue collar group(p<O.05). 5.The comparative analysis of social factors in two groups showed differences with respect to the using bed, walking amount, health state, physical exercise in White collar group(p<0.05); and walking amount, physical exercise in Blue collar group (p<0.05). Especially, Blue collar group showed high differences with respect to the health state(p<0.01). 6.In regard to the general aspects of back pain between two groups, there were differences concerning etiolgy of back pain, pain duration, counselling partners, treatment types, and sick-leaves(p<0.05), except awareness of back pain.
