This study compared and analyzed the time-records between two books that is, the best new world record book issued by I.A.A.F and the track and field record book issued by A.T.F.S by using the regression and ratio-increasing method. Two books consist of the world records and the annual world records, respectively. This study aims to predict how the 2000-year world record and the annual world record would be changed. Based on the analysis, time recorded of 2000 year 100m race would be predicted as follows; 1. Men's world record was estimated to 9.68 seconds (regression method), and 9.66 seconds (ratio-increasing method). And annual world record was estimated to 9.75 seconds (regression method), and to 9.74 seconds (ratio-increasing method), respectively. 2. Women's world record was estimated to 10.34 seconds (regression method) and 10.14 seconds (ratio-increasing method). And annual world record was estimated to 10.43 seconds (regression method), and 10.11 seconds (ratio-increasing method), respectively.

A 14-year-old male pomeranian was present with swollen left ear. The swelling occurred from base to apex of pinna. Otitis externa persisted for two years. Hematological and serum biochemistry values were not remarkable. The surgery treatment was the most appropriate method among indwelling drain, surgical, and steroid treatment in the aural hematoma because the dog was very sensitive to touching pinna and the size of aural hematoma. Longitudinal incision was applied after general anesthesia. Cefovecin was injected to prevent secondary infection. The outcome of surgery was good. There was no evidence of recurrence for one year.

Concerning with the mechanics of wool crimps deformation, the tensile and torsional behavior along the longitudinal axis have been studied by many authors. However, published papers reporting the lateral behavior are extremely limited in number. In the present study, attempts have been made to investigate the lateral compressive behavior of wool crimps (Polwarth 65'^s ram). The main results are; 1) For the crimps of sine curve form, the variation of E.C.D. may be obtained by var.E.C.D.=(FR^3)/(4EI)(π-8/π) 2) For the crimps of helix form, the lateral compressive force F per pitch is obtained by the sum F_1+F_2, where F_1 is the force due to the bending deformation and F_2 the force associated with the torsional deformation.

Asthma is a chronic inflammatory disease of the airways, characterized by airway eosinophilia, goblet cell hyperplasia with mucus hypersecretion, and hyper-responsiveness to both inhaled allergens and nonspecific stimuli. Eosinophil are important in the pathogenesis of asthma, with release of inflammatory mediators such as histamine, leukotrienes, cytokines, and IgE after exposure to allergen. Objectives : This research investigates the effect of the extract of Duchesnea chrysanta (EDC) on OVA-indued asthma murine model. Methods : After i.p of C57BL/6 mice, OVA sensitization (day 0) were challenged intratracheally with OVA on days 8 and 21. EDC administered weeks 8, blocked the airway inflammatory response to OVA assessed 24 h after the last OVA challenge on day 22. Results : The CC chemokine receptor 3 (CCR3) is expressed by eosinophils, mast cells, and Th2 cells. The role of CCR3 in a murine model of allergic skin inflammation induced by repeated epicutaneous sensitization with ovalbumin (OVA), and characterized by eosinophil skin infiltration, local expression of Th2 cytokines, and airway hyperresponsiveness (AHR) to inhaled antigen. The administration of EDC during OVA inhalation significantly reduced CCR3 plays an essential role in eosinophil recruitment to the skin and the lung and in the development of AHR.. EDC extract reduced total lung cells and eosinophils in bronchoalveolar lavage fluid, airway tissue eosinophilia, goblet cell hyperplasia, mucus secretion, and peribronchial edema. The inhibitory effect on airway eosinophilia and AHR was associated with reduced levels of IL-4, IL-5, and IL-13 in the bronchoalveolar lavage fluid as well as reduced serum levels of OVA-IgE. We show that OVA inhalation following OVA immunization increased airway responsiveness to induced IL-113, IL-4 and IL-5 mRNA expression in the lung tissue. The administration of EDC during OVA inhalation significantly reduced this increased airway hyperresponsiveness and also inhibited airway inflammation. Conclusions : These results support EDC as a therapeutic target in asthma and indicate that selective EDC inhibitors can reduce allergic airway inflammation.

Steroid cell tumor is a rare ovarian sex cord-stromal tumor which accounts for 0.1% of all ovarian tumors. Until now, only 4 cases have been reported in domestic literatures. Steroid cell tumor often secrets testosterone and presents virilization in adult women or precocious puberty in children. Treatment is often performed by surgical removal, adjuvant chemotherapy and radiation, but completely accepted treatment was not existed. We experienced a case of steroid cell tumor, which was manifested by typical virilization in a 43-year old patient, who was previously performed hysterectomy and unilateral oophorectomy. So, we present with a brief review of the literatures.

Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.

전북 부안 유천리 청자요지에서 수습된 청자편 11점의 태토 및 유약에 대하여 화학조성을 분석하고, 기 발표되어진 문헌의 청자데이터들을 종합하여, 이와 비교함으로써 본 시료의 도자특성과 및 산지에 대한 정보를 유추하였다. 태토의 주요산화물 분석에는 XRF를 이용하였으며, 유약의 주요산화물분석에는 EPMA를 이용하였다. 태토 중 17개 미량성분의 분석에는 ICP-MS를 이용하였고, 자료의 비교분석에는 Seger식에 의한 방법과 주성분분석법에 의한 통계처리방법을 병행하였다. 태토의 주요산화물에 대한 비교분석결과 유천리 청자는 Seger 식과 주성분분석에서 RO_(2)와 RO+R_(2)O가 6~8 및 0.3~0.38 mole로, 또 높은 SiO_(2)함량과 낮은 Na_(2)O, CaO의 함량으로 전북지역의 데이터 범위에 분포함을 볼 수 있었다. 유약의 주요산화물에 대한 비교분석결과에서는 Seger식과 주성분분석에서 모두 명확한 지역구분이 나타나지 않았으며, 따라서 유천리 청자 역시 명확한 지역적 특성을 구분하기 어려웠다. 태토중 미량성분의 주성분분석에 의한 통계처리결과 광주 충효동 도편들을 제외하고는 뚜렷한 지역간의 구분을 관찰하기 어려웠다. The characterization of chemical properties and analogy of manufactured origin for the eleven celadon sherds collected in Yuchunri, Buan were performed by analyzing their body and glaze compositions and compared with previous data reported. The chemical compositions of the body and glaze were determined by XRF and EPMA, respectively. The trace elements of the body were also determined by ICP-MS. The Seger analysis and PCA were used to compare the major compositions of body and glaze of the potteries we found with previous data. The Celadon sherds from Yuchunri are distributed in a range of Chonnam potteries considering RO_(2) and RO+R_(2)O are 6~ 8 and 0.3 ~O.38mole, respectively and also high in SiO_(2) and low in Na_(2)O and CaO concentrations in the comparison between the potteries for the major compositions of the body. Differences of the chemical characteristics of those potteries between the provinces were not clear in comparison of the glaze compositions and trace element of the body.

Seo, Ki Cheol,Park, Hwa Sik,Hwang, Ho Jung 대한전자공학회 1989 ICVC : International Conference on VLSI and CAD Vol.1 No.1

This paper presents an investigation of numeric approaches to efficient solution of diffusion equation describing the two-dimensional impurity redistribution phenomena in a semiconductor during thermal oxidation. An approximate expresson is derived to model the two-dimensional diffusion of tow-concentration impurities and they include detailed considerations of ambient effects. The kinetics of oxidation including concentration dependence and interaction of oxide growth with impurity migration are considered as well as the segregation phenomena. The numerical method to solve the two-dimensional moving boundary problems uses boundary element techniques which based on Green's function. Various approaches to improve stability such as time step control, numerical integration method are discussed.
