As a result of the enlarging pool of unvaccinated children and young adults, there has been an increase in measles in our countries. In these situation, it has been reported that measles associated pneumoinia is easily complicated with fatal respiratory failure, espycially in immunocompromised patients. Herein we report the case of lethal measles pneumonia after allogenic hematopoietic stem cell transplantation in adults proven by autopsy. Recently, one case of measles was encountered in 39-year-old female patients after allogenic bone marrow transplanted case (chronic myelogenous leukemia), who progressed into interstitial pneumonia pattern, despite treatment including antibiotics, immunoglobulin. The patient died of giant cell pneumonia compatible with that of measles which was comfirmed in the section of necropsy lung specimen. (Korean J Infect Dis 33:301∼309, 2001)

체성 연부 조직에 생기는 평활근육종은 매우 드물다. 66세 남자 환자가 방사선 소견상 경계가 좋은 양성 종양이 의심되어 절제술을 시행 받았다. 육안조직소견상 경계가 좋은 둥근 종괴이나, 현미경 소견에서 세포충실도가 증가되고 부분적으로 중증도의 핵이형성을 보였다. 또한 면역조직화학염색상 Smooth muscle actin과 Desmin에 동시에 양성이어 평활근세포 기원으로 생각되었다. 저자들은 괴사가 없고 유사분열은 단 한 개만이 관찰되었으나 중증도의 핵이형성을 보였기에 평활근육종으로 진단한 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Leiomyosarcoma of somatic soft tissue is a rare tumor compared with retroperitoneal lesion. We report a case of a leiomyosarcoma of the somatic soft tissue in a 66-year-old man. He presented as an enlarging mass in the left thigh for eight months. Radiologic examinations revealed a well defined round mass, suspicious of benign tumor, such as hemangioma or leiomyoma. He underwent surgical resection. The mass was 3.0 cm in diameter, and it was confined within adductor longus muscle without any connection to adjacent neurovascular bundles. Histologic examination showed moderately cellularity and focal marked atypia with a fascicular growth pattern of spindle cells showing blunt ended nuclei. In addition, the proliferation index was 2~3% by immunohistochemistry using monoclonal antibody MIB-1. But only one definite microscopic mitotic feature was found. Although it showed low mitotic activity without necrosis, this case was diagnosed leiomyosarcoma according to marked cellular atypism.

Social redemption of development-benefits becomes the most important issue in shifting our 19800's development policy to growth management. Its reasons are as follows. In general, growth management policy has six objectives: first, it prevents extensive expansion of urban; second, it sustains equilibrium of development-benefits; third, it strengthen socio-economic poley and stabiliy of real estate market; fourth, it improves living environments and protects natural environments; fifth, it enlarges citizen's participation in urban development; sixth and finally, it systematizes and prepares of developmental laws and regulations. Development-benefits whcih obtained by national policies, public investment or decisions, must be redeemend to society. for example, if there were a landholder who has enormous unfair profits, simply because his land located in development area by mere chance on the one hand, while on the other hand there were residents who burden more taxes without any development-benefits, especially any one whose land included in partly or entirely public undertaking land, should be moved away from beloved habitat and neiborhoods to an unfamiliar place with dissatisiactory compensation, social equilibrium should never be realized. Simultaneously, I think our 1980's national develnpment goals-balanced local development and solution of unbalanced local development-should be accomplished, after benefits obtained by development could be redeemed to the competent community and equitable compensation were realized. Accordingly, public concept of estate ownership must be introduced in order to change the nation's chronic thoughts about estate ownership, and balance of benefit-redistribution is required. Present institution in order to implement development-benefits redemption will be transferred as such amended institution-that is-shifting transfer-income taxe from now national taxe to local taxe in taxable redemption method, and benefit-burden system that is untaxable redemption method will be integrated, or through integration of laws and regulations, for example, by establishing newly "development-benefit taxe" (or regional development taxe) with taxable redemption method. And if redeemed development-benefits are used financial resources of local government, its finances that responds to satisfy to basic needs of residents will be reinforced and regional development projects will be activiated. Ultimate goals in social redemption of development-benefits will be not only sustained balance of urban development and settled real estate market, but also constructed pleasant urban environments and improved benefits of citizen's livings.

Data obtained from the subsurface exploration in Nak-dong river basin have been analyzed to characterize the general patterns of the soil strata and soil characteristics of soft ground. The soft soil is widely distributed over the entire plain adjacent to the Nak-dong river including the deltaic area in the mouth of a river. The soft clay layer is located below the top sand layer and it is sometimes found below the bottom sand layer in some restricted areas. The physical characteristics in the alluvial layer exhibited a widely scattered distribution and no clear pattern. The natural water content increased from the surface and reached it maximum value at the depth of 20m and thereafter it tended to decrease with depth. The unit weight showed a similar pattern to the natural water content. The soil was classified as CL or CH according to the unified soil classification system. The mechanical characteristics showed a tendency to increase with depth whereas the undrained shear strengths did not. The distribution of sensitivities of the soft clay showed no relation with depth. The values of overconsolidation ratio were distributed widely depending on the site but most of them were concentrated between 0.8 and 1.0 The values of compression index ranged between 0.2 and 1.2 but they showed great differences in the same area.

This paper suggests a fuzzy control algorithm which manipulates the quantity of gas in a gas storage tank to a given reference value. Fuzzy control rules proposed in this paper are divided into two groups. The first is to treat the quantity of gas in a gas storage tank, and the second is to manipulate the quantity in pipe which is utilized in moving gas from gas source to a gas storage tank. Fuzzy control rules to treat two control problems mentioned above are designed independently by investigating several special points having inherent features for given assumed possible response characteristics in the sense of common-sense and engineer's technical knowledge. In order to observe the validity of fuzzy control algorithm for manipulating the quantity of gas in a gas storage tank suggested in this paper, computer simulations are done for three cases, which the quantity of generated gas and the required quantity in load have time-varying patterns. Computer simulation results show that fuzzy control rules designed in this paper are well operated for every case.

본 연구에서는 CSM 에멀젼의 물성을 향상시키고자 금속성 가교제인 magnesium carbonate 및 calcium hydroxide를 첨가하여 가교밀도, 열적특성, 표면자유에너지 그리고 인장강도, 파단신율 및 인열강도 특성을 고찰하였다, 금속성 가교제인 magnesium carbonate 및 calcium hydroxide 양이 증가함에 따라 CSM 에멀젼 필름은 가교밀도는 증가하였고, 이에 내수성과 T_(g) 값도 증가하였다. 금속성 가교제로 magnesium carbonate를 첨가하였을 때 calcium hydroxide에 비해서 다소 높은 가교밀도와 T_(g) 값을 보였다. 하지만 CSM 에멀젼 필름의 표면에너지 및 기계적 특성들은 다소 다른거동을 보였다 Magnesium carbonate 0.75% 그리고 calcium hydroxide 1.0% 첨가한 경우가 가장 높은 표면 자유에너지 값과 인장강도 및 인열강도를 보였으나, 그 이상의 양을 첨가하였을 경우에는 오히려 감소함을 확인하였다. 그러므로 본 연구에서 CSM 에멀젼의 물성을 향상시키는데 적용되는 금속성 가교제로서 calcium hydroxide 보다 magnesium carbonate가 더 적당하며, 0.75% 첨가하였을 때 보다 향상된 물성을 얻을 수 있었다. In this work. magnesium carbonate and calcium hydroxide as metallic crosslinking agent were added to chlorosulfonated polyethylene rubber (CSM) emulsion to enhance the mechanical properties of emulsion film such as tensile strength. elongation at break, and tear strength and crosslinking density. thermal features, and surface energy were also investigated. Crosslinking density of the CSM emulsion film with increasing the amount of magnesium carbonate and calcium hydroxide increased. leading to the enhancement of water resistance. It was shown that compared with calcium hydroxide, magnesium carbonate had a little higher crosslinking density and To value. The surface energy and mechanical characteristics of the CSM emulsion film, however, showed somewhat different behaviors. The highest surface energy. tensile strength. and tear strength were observed when 0.75° o for magnesium carbonate and 1.0° o for calcium hydroxide were added respectively. Therefore. it can be concluded that as metallic crosslinking agent to improve water resistance and mechanical properties of the CSM emulsion, magnesium carbonate is more preferable to calcium hydroxide

Land itself is a gift of natural resources given to human beings together with airs and waters. All the land problem on occuring on land is, therefore,concentrated on this conflict concept;between preservation as a comfortable space of life evin though it is limited and development which shoule be proptionally and efficiency. Accomplishing the rapid economical development based on growth-oriented policy from the 1960',our country made a so rapid progress on urbanization, industrialization,increase in population and centralization to large cities that land problem became more serious after it had come to the front as a political and social problems. We must try to find soltions to this problem as a defferent aspects compared to the relatively good land circumstanves'country,because our country is situated on a limited land and top level of popultion density n world. First, precaution on disorderly development and on external expansion of city resulted from centralzation of population and industries is necessary. And pre-vention of waste and destruction on natural environment by balancing develop-ment and preservation must be followed. Second, prevention of skyrocketiong land costs resulted from speculation and cornering of land and subsequent bad influeces resulted from sudden rises of land costs must be made and prohibited . And also,securing of stable and pro-portional tilization and development on lands must be followed in the long term's sense. Third, the thoughts of promoting the public welfare must be implanted to the people and securing of economical efficiency on limited land resources is important. Land, as a space for fndamental life, is not only belonging to our own but also eternal property which must be descended to our posterity. So, I would like to suggest for improvement of present problematic land policies as follow;①Fundamental blockade is necessary for speculative transac tions on urban land. ②Promoting the preservation of natural resources and the efficiency of land utilization. ③Promoting the social restoration of development profits and also promoting the auto-propulsion of city construction at a low cost. At the same time, Betterment be directed to lubriate the house supply. And means of policy are as follows; ①Making public ownership for urban land is necessary and it must be to establish special law for it's reasonable management. ②Not only unify and readjust on present various land-related laws, but also establish or appoint the organizaton which will take exclusive responsibilty of land management, By doing so, the basic prolem on land development, that was suggested in the all-ot program for land development on land resources, for example,①overcome the restriction ②promote the efficiency ③promote the publicity ④harmonize development with preservation, I must say, will be accomplished and settled.

p-type InP 표면에 미치는 H₂S 플라즈마 Passivation 효과

이영철,최병건,한교용 嶺南大學校 工業技術硏究所 1997 工業技術硏究所論文集 Vol.25 No.2

The effects of H₂S plasma passivation on p-type InP surface have been characterized by performing PL measurements. PL samples were fabricated under different RF power and different exposure time. After exposing them to H₂S plasma, their surface was covered by RF sputtered ITO film. Our PL results showed that RF power and exposure time should be optimized to obtain better surface passivation. In order to investigate surface type conversion by H₂S plasma, ITO/InP solar cell was fabricated and electrically characterized. The solar cell showed the typical I-V characteristic curve of a pn diode, which demonstrated the formation of pn junction by H₂S plasma.

This paper presents a fuzzy control algorithm which manipulates the calorie of a mixed gas generated by combining two kinds of gases to a specified target value. A suggested fuzzy control algorithm is functionally divided into two groups. The first is a feedback control function which eliminates error between the target value and output value of a mixed gas calorie by analyzing a measured output value of a mixed gas calorie. The second is a predictive or feed forward control function which reduces anticipated such calorie error by investigating variation patterns of quantity and calorie of a gas to be mixed. In order to show the validity of proposed in this paper, computer simulations are performed for three cases with the features of varying quantity and calorie. Computer simulation results show that mixed gas calorie is well controlled for each case.
