Amidst increasingly growing demand for large concrete structure or high strength / high durability concrete in line with economic development, the risk of ydrothermal cracking resulting from hydration heat and drying shrinkage has been on the rise, In fact, thermal stress caused by hydration heat or contraction stress due to drying shrinkage has considerable effect on design or construction of the structure. The cracks in concrete structure spoils the aesthetic aspect of the structure as well as deteriorates the load bearing capacity of the structure, thereby worsening the usability and safety and reducing the service life of the structure eventually. Moreover harmful substances penetrated into the crack causes the rebar to be corroded more rapidly and other numerous problem. In this study, inspection of the urban railway pier structure was performed to check the cracks and in a bid to identify the cause of the cracks, modelling to simulate the field condition was implemented and the temperature distribution and thermal stress variat ion occurred inside and outside the members were estimated using 3D finite element analysis program, MIDAS/FEA and the thermal cracking index was calculated and analyzed.

Since the first year economic development plan, imblanced development of national territory during the economic development process has aggravated remarkable disparity between urban and rural areas. For this reason, this study introduced the development of rural market as one of the development strategies of regional economic to correct the imblance and relieve regional disparity. The purpose of this study were to look into the present situation of traditional rural market and to analyze the problems for the rural development in view of the current road situations in the rural areas and status of marketing facilities in market center and to measure the degree of rural area people's satisfaction to the rural market and to suggest the development plan of activating for rural market center. To collect data, the Yesan Gun rural market were selected and a total of 591 residents and 178 merchants were sampled as final subjects of survey. Interview and/or questionnaire method was the main method of data collection. The major findings of this study were as follows: 1) The population of Yesan Gun has decreased 2.85 persons per year from in 1984, but the number of vehicles were increased 2.85 times than in 1989. And the parking capacity of Yesan Eup was only 129 vehicles which were below of the total vehicles of Yesan Gun area (14,352). The number of Yesan area markets were 8 markets which consisted of 1 permanent market and 7 periodic markets. But as the economy has been developed, the conditions of rural markets have been changing. That is, the role of periodic market tends to be weakened with the growth of large cities, reinforcement of permanent markets, development of traffic facilities, large production, preferring high quality goods. 3) Generally, the people of Yesan Gun were attached for purchasing the necessaries of life and comodities and farming materials to ① Yesan Eup ② Seoul ③ Chonan Shi ④ Hongsung gun ⑤ Daejeon Shi. 4) The degree of community people's satisfaction to the town market presented 26.6% which meaned higher than dissatisfaction(9.5%). And the degree of people's inconvenience of accessibility to market center by transferring of bus terminal presented 64.2% which meaned higher than average. 5) The degree of people's dissatisfaction of traffic system in Yesan gun area presented followings: the road networks(61.5%), parking facility(68%), bus route(54%). 6) By the survey of merchants of Yesan gun area, on the average, it showed followings: the size of store was 6-10 pyeong(40%), the type of enterprise was retail dealer(70.9%), and purchasing place was wholesale dealer from Seoul(51.8%). 7) And they thought that Yesan town market were too small(70.8%), and the diversifying of goods was not enough(35.5%). 8) The merchants of Yesan area showed that the degree of into venience to traffic system was 72.7% and its to parking facility was 83.3%. And they complained that community administration agency have not tried to activate market(79.1%). Based on the results of this study, the following recommendation were made for activating regional economy and community market. That is, it is to strengthen the economic function in community market so as to suffice the economic and social activities for settlement area as their living space. And it is necessary to improve the interrelationship of the central functions. 1) So, the accessibility between market center and its surrounding areas must be rised. ① the enforcing preferentially to pave the bus terminal and market center to link two place. ② the running of shuttle-bus two place every regular market day. ③ the widening and connecting the road to rise accessibility between market center and its surrounding area. ④ the enforcement of parking facility around market center. ⑤ the constructing marketing centered area as intergrated body of various marketing facilities in the adjacent site is the centered area planned to achieve efficient marketing. 2) The modernization and specialization market center facilities. 3) The strengthening of drawing surrounding area people into Yesan market center. So, the following recommended: ① the development of special products market ② inducing special projects ③ the development tour and leisure course drawing industrial facilities. 4) And it needs to enforce community people's local patriotism and to support community markets by administration agency.

Purpose: The gastrointestinal (GI) tract is the most common site of extranodal non-Hodgkin's lymphoma (NHL), which is increasing in incidence, but there is no established optimal treatment modality. Thus, this study was investigated the clinicohistologic feature, the therapeutic modalities, and the prognosis for GI-NHL, as well as the factors affecting it. Methods: We retrospectively analyzed 45 patients who had been diagnosed as having GI-NHL and had been followed up from July 1994 to February 2005 at Soonchunhyang University Hospital. The patients were divided into groups according to the site of origin and to various other features, and the survivals of the various groups were compared. The modified Ann Arbor system and WHO classification were adopted for staging and histopathologic classification, respectively. Results: GI-NHL of the stomach, small bowel, ileocecal region, and colon occurred in 28 patients (62.2%), 5 patients (11.1%), 3 patients (6.7%), and 8 patients (17.8%), respectively, In one patient, the entire gastrointestinal tract was diffusely involved. The median age of patients was b5 years (25~78 years), and male-to-female ratio was 1:1.1. Fourteen patients were in stage Ⅰ, 24 in stage Ⅱ, 4 in stage Ⅲ, and 3 in stage Ⅳ. Surgical resection was performed in 19 patients, and combination chemotherapy was performed in 43 patients. Surgical resection only was performed in 4 patients, Chemotherapy only was performed in 26 patients. The expected overall 5 year survival of 45 patients was 39.6%, and there was a significant survival difference between the stages, but between sites of origin (p=0.842). The most important factors influencing the survival was the stage and other factors were not significant. Conclusion: The stomach was the most common site of GI-NHL. Most GI-NHL were localized Stage was the most important prognostic factor. However, Prospective randomized studies are needed to approve the therapeutic modality.

폐결핵 환자 혈청에서 수용성 Interleukin 2 수용체 및 Adenosine Deaminase 활성도에 관한 연구

고정희,박성규,백상현,박찬권,박병수,안진영,최우석,박정규 충남대학교 의과대학 지역사회의학연구소 1993 충남의대잡지 Vol.20 No.1

Interleukin-2 (IL-2) induces T cell proliferation in an autocrine manner and provides a means by which antigen triggered T cells can be clonally expanded in vitro. During the following activation, the activity of IL-2 is mediated by specific high affinity IL-2 binding membrane receptors which are expressed shortly after activation. In this process, a 42 KD-fragment (soluble IL-2R) is continuously cleaved off and circulates as a soluble marker of T lymphocyte activation. Elevated level of soluble IL-2R has been identified in the serum of patients with malignant autoimmune and allergic disorders, systemic parasitic infection, undergoing graft versus host disease, acute or chronic lymphocytic leukemia and HIV-infection. ADA (adenosine deaminase) completes the process of differentiation of T cell and is essential for progression of T cell maturation. Therefore level of ADA is to correlated with magnitude of T cell immune response. The fact that expression of sIL-2R and ADA activity increases in peripheral blood T-lymphocytes of patients with active pulmonary tuberculosis suggests that T cell activation might have a major role in the pathogenesis of pulmonary tuberculosis. In order to evaluate the T cell immune response in pulmonary tuberculosis, we measured the serum concentration of sIL-2R and ADA activity in 17 patients with current pulmonary tuberculosis, 10 chronic inactive pulmonary tuberculosis, 10 as normal controls. (1) Current pulmonary tuberculosis had significantly higher levels of sIL-2R (237.24±95.47)when compared with those of inactive tuberculosis (78.6±11.06). and the control (68.17±15.4) group. (2) ADA activity in current pulmonary tuberculosis was significantly increased (34.41±20.63) when compared with those of inactive tuberculosis (24.7±14.36) and control (17.65± 5.94) group. (3) There was good correlation between sIL-2R concentration and ADA activity in serum in current pulmonary tuberculosis group. (4) sIL-2R concentration and ADA activity was decreased significantly 6 months after anti-tuberculosis drug medication. In conclusion, sIL-2R concentration and ADA activity in serum in current pulmonary tuberculosis group was increased when compared with those of inactive pulmonary tuberculosis and the control group. By the way, T cell mediated immune response was enhanced in current pulmonary tuberculosis, but in inactive chronic pulmonary tuberculosis who had treated by antituberculosis drug medication, the concentration of sIL-2R and ADA activity was nearly normal.

The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.
