癌患者의 腹水 및 肋膜渗出液이 健康人 淋巴球의 Rosette形成에 미치는 影響

河大有,鄭憲鐸 大韓免疫學會 1979 大韓免疫學會誌 Vol.1 No.1

Non-specific suppressions of delayed-type hypersensitivities (DTH) measured by skin reactivity to certain antigens, response of lymphocytes to mitogens and spontaneous(E) rosette formation of lymphocytes with sheep red blood cells (SRBC) have been reported to occur in cancer bearing-patients. The mechanisms responsible for these immunosuppressions remain unclear, but some investigators suggested that the immunosuppressions may result from immunosuppressive factors exudated from tumor masses. This study was undertaken to evaluate the effect of ascitic and pleural fluids from patients with cancers metastatic to peritonium or pleura. Non-cancerous ascitic and pleural effusions were used as controls. The ascitic and pleural fluids from hepatoma patients and pulmonary carcinoma patients decreased not only the percentages of early and late rosette formations severely but also the affinity of lymphocytes to SRBC. On the other hand ascitic fluids from stomach cancer patients increased the percentages of early rosette formation and the affinity of lymphocytes to SRBC. Control effusions exerted no effect on rosette formation except the pleural effusions from pulmonary tuberculosis patients. Pleural effusions obtained from tuberculosis patients slightly increased the percentages of rosette formation and the affinity of lymphocytes to SRBC.

Background: This study was designed to analyze the current emergency department(ED) medical records of teaching hospitals in Korea. Methods: The five-item questionnaires were mailed to the EDs of 40 hospitals. Among them, 27 questionnaires and 35 ED medical records were returned for reply rates of 67.5% and 87.5%, respectively. Results: 1) The actual number of data elements in the ED medical records used by each hospital varies widely. It ranges from 1 to 15 data elements with an average of 7.5 data elements. 2) Thirteen data elements, signature of nurse, checklist style in review of systems, checklist style in physical examination, neurologic examination, figure of face, Glasgow coma scale, trauma scale, treatment plan, mode of transfer, condition on transfer, documents sent with patient, condition on discharge or discharge instruction, use of pediatric chart and vaccination history are used by less than 50% of the medical records examined. 3) There was no difference in the total number of data elements or in redesign and computerization of ED medical record based on the location of the hospital, the type of hospital administration, or the number of years since the start of EM residency program. 4) There was a statistically increased number of data elements in redesigned medical records. 5) In the survey, 89% of the residents replied that medical records needed to be redesigned. With respect to uniformity, 58% of the residents disagreed. A well-designed checklist chart rather than a descriptive chart was preferred by 89% of the residents. Conclusion: The currently used ED medical records have much room for improvement. The age of the ED had little impact on the quality of ED medical records. More attention and effort in this field are needed. In addition, The Korean Society of Emergency Medicine should provide guidelines for ED medical records.

3-Methylcholanthrene에 依하여 誘導된 腫瘍마우스의 緬羊赤血球에 對한 免疫反應

鄭憲鐸,河大有 大韓免疫學會 1979 大韓免疫學會誌 Vol.1 No.1

This study was undertaken to evaluate the immunological capacity of the mice bearing tumor induced by 3-methylcholanthrene (3-MCA). The age matched normal mice were used as control. Mouse skin tumor was elicited by topical application of 0.2m1 of a 0.4% aceton solution of 3-MCA on the shaved dorsal skin and concomitant intramuscular inoculation of 10g prostaglandin Fa. (PG F:a) three times a week for two months. The cell-mediated immune response was determined by measuring the footpad swelling reaction and the humoral immune response was determined by easuring the antibody formation to sheep red blood cells (SRBC). In addition, 4 hour's skin reaction to SRBC and rosette formation of spleen cells with SRBC were measured. All of the immunological parameters used in this study were lower in the tumor-bearing mice than in the normal mice. Among the parameters, the footpad swelling reaction was most severely depressed in the tumor-bearing mice. The titers of hemagglutinin and hemolysin were slightly lowered and both titers of mercaptoethanol-resistant (IgG) antibody and mercaptoethanol-sensitive (IgM) antibody were decreased in the tumor-bearing mice. The spleen weights were strikingly increased in the tumor-bearing mice. However, the numbers of rosette forming spleen cells were slightly decreased in the tumor-bearing mice. The four hour's skin reactions were also depressed in the tumor-bearing mice. This study clearly indicates that malignant tnmor suppresses the immunological responses of host, paricularly cell-mediated immune response.

This study was undertaken to measure peripheral blood T-lymphocyte during the various phases .of the normal menstrual cycle and to investigate the circadian variations of peripheral blood leukocytes. The experiment was carried out on three medical students in the dark-room under the light-dark regimen of L. D. 17: 7 for circadian rhythm and on fifteen nursing students under the normal life pattern for lunadian rhythm. A significant decrease in T -lymphocytes occurred during. the menstrual period. However, the percentages of T -lymphocytes returned to the pre-levels one week after the end. of the menstrual period. On the other hand, total numbers of lymphocytes and neutrophils showed ' no changes during the menstrual period. The acrophase of peripheral neutrophil count was in the early stage of activity span whereas the acrophases of peripheral eosinophil count and lymphocyte count were in the midstage of the rest span.

Biochemical changes and icon of platelets on platelet concentrates preserved for a 5day term in several plastic containers were investigated. The authors evaluated the TOTM-PVC second generation container produced by Green Cross Medical Corp. and Boin medica. Blood obtained from 40 persons was manufactured for platelet concentrates within 4 hours and each divided into 20 units of platelet concentrations. Samples were taken at 0, 3, and 5days and the platelet count, pH, pO_(2), pCO_(2), HCO_(3)-, glucose, LDH, lactate, electrolytes, and mineral element were tested The number and MPV, for platelets icon, were well preserved on two different platelet concentrates during storage. A test for biochemical function appeared to be effective data. pH was maintained above 6.8 on two different platelet concentrates during storage. The results suggest that the TOTM-PVC second generation platelets storage container produced by Green Cross Medical Corp. and Boin medica was able to preserve platelets for at least five days without lesion and was it concluded to have biochemical efficacy on patients with transfusions.

The College of Engineering was specialized to have a sole function for supplying technical high school teachers in 1977 and referred to as the College of Industrial Education according to the Government's policy. The economic impact mainly due to the oil-crises caused a severe problem to this college, namely discrepancy of supply to demand scale. Accordingly the number of student enrollment was to be fluctuated from 479 in 1979 through 800 in 1979 and 900 in 1980 to 430 in 1981. And the engineering departments have been attached to this Engineering Education College since 1981. These circumstanses met singnificant inefficiency in facility operation. This program aims at providing an overall relocation of the college facilities and preparing the practical system to make the joint-operation possible taking into account circulation, academic stream, budget, maintenance, etc. However this study could not get optimal spacing but some trade-off, considering the current situation.

As use of the visual display terminal(VDT) is becoming more generalized as a result of office automation, the so-called 'VDT syndrome' which is often observed with the workers using VDT has emerged as a serious occupational health problem. However, few comparative study with control group using not only subjective symptom but also physical examination has been conducted. We have conducted a study comparing prevalence rated of musculoskeletal disorder between 113 VDT operators of a telecommunication company and the control groups of housewives and office ladies through a review of subjective symptoms as well as physical examination by physiatrist to understand the magnitude of problem and relative risk of VDT worker. The symptom rates of upper extremity disability in VDT operators were higher than those of controls especially in neck and shoulder area. Fifty-four(47.8%) of 113 VDT operators met our case definition of upper extremity disorder by subjective symptom and physical examination. Myofascial pain syndrome of neck and shoulder muscles were the most common(46.9%). The odd ratio of using VDT operation for developing myofascial pain syndrome in the neck or shoulder area were 2.52(compared to controls of office ladies) and 2.64(compared to controls of housewives). Other anatomical lesion such as elbow, hand and wrist shows slight higher prevalence rates of musculoskeletal disorder than control groups but not statistically significant.

A Study on the Regional Innovation in an Industrial Cluster : Focusing on a Traditional Textile Industry of Nishijin Area

Tai Hun Lee,Soon Goo Hong 보안공학연구지원센터 2016 International Journal of u- and e- Service, Scienc Vol.9 No.4

Fabric from Nishijin occupies a significant position in traditional Japanese culture and it holds a large industrial share in Kyoto City. This paper examines the regional “hollowing out” that has caused a decline in the industries surrounding Nishijin, as well as social changes, including building deterioration and regional economic stagnation and to suggest policies for regional innovation. The direction of political responses to this situation is also considered. To understand the uniqueness of Nishijin fabric and the potential that has accumulated over the process of industrial development, the structural change of Nishijin industry was investigated using statistical data from the “Nishijin Industry Survey Summary (2005, 2011).” The change in the cluster degree was also examined using Kyoto City Industry Statistics and the specialization coefficient. The implications of this study can be summarized as follows. First, the hollowing out of the manufacturing industry and regional stagnation in Nishijin can be attributed to diminished trust within the community following outsourcing and cost transfers to small Hataori. It is recommended that a new collaborative relationship be established where diverse interested parties participate from the beginning of production based on the concept of co-creation. Second, while textile manufacturing-related industries in Kyoto City are declining overall, Nishijin has experienced a relatively mild decrease, resulting in a cluster with a relatively higher degree of textile manufacturing. As long as Japanese society exists, there will be a demand for a traditional clothing. Therefore, industries should recover to bring new investment and regional innovation through reshoring. Third, a specialization coefficient analysis indicated that there exist irreplaceable products, such as materials manually woven by master craftspeople and finest quality fabricated thread.

The Determinants of Infant and Child Mortality in Korea: 1955-1973

Tai-Hun Kim 한국인구학회 1986 한국인구학 Vol.9 No.2

In both urban and rural areas, mother's education is the most important determinant of infant mortality, maternal age and number of rooms used are the main determinants of child mortality. Previous birth interval and survival of the previous birth also significantly affect infant mortality and previous birth interval child mortality in both urban and rural areas. For both infant and child mortality previous birth interval and number of rooms used are the most general factors in urban areas; previous birth interval and mother's education in rural areas. Infant mortality is also significantly affected by sex of the child and the number of rooms used in urban areas, and by birth order in rural areas. Significant determinants of child mortality are birth order in urban areas but mother's education in rural areas. Thus, in summary, demographic factors are relatively more important for infant mortality in the rural areas and for child mortality in the urban areas; in contrast, socioeconomic factors play a role for infant mortality in urban areas and for child mortality in rural areas.
