저자들은 중증 재생불량성빈혈로 동종 골수이식 및 추가적인 동종 말초혈액 조혈모세포이식을 시행 받은 후 만성 이식편대숙주질환이 발생하여 면역억제제로 조절되었으나 자가면역성 갑상선기능항진증이 병발한 1예를 경험하였기에 이를 보고하는 바이다. Chronic graft-versus-host disease (GVHD), which is a frequent complication following bone marrow transplantation (BMT), is characterized by fibrosis of the skin, liver, lungs, and gastrointestinal tract, immunodeficiency, and the production of autoantibodies. Endocrine dysfunction, in particular thyroid disease, has been described following BMT, but this has previously meant hypothyroidism secondary to total body irradiation or transfer of autoimmune hyperthyroidism from a donor with Graves’ disease rather than in association with chronic GVHD. We report a case of a 26-year-old man who developed Graves’ disease eight years after BMT and who had remission of chronic GVHD. He received an allogeneic BMT for severe aplastic anemia. Eighteen months after BMT, diarrhea and chronic GVHD developed and were treated with cyclosporine and steroid. Four years after ceasing the cyclosporine, the patient developed weight loss, palpitations, fever, and anterior neck swelling, and was diagnosed with Graves’ disease based on typical thyroid function tests. The signs and symptoms in the patient improved with propylthiouracil and propranolol.

The current study was designed to evaluate the positive rates of arthropod allergens by Korean inhalant panel of MAST-CLA in patients with allergic rhinitis. One hundred sixty patients, diagnosed to allergic rhinitis in an Out Patient Center of Soonchunhyang University Chunan Hopsital during Aug 1998 to July 2000, were studied. 1. The overall positive rate among 35 specific allergens was 59.4% (95 patients). 2. The arthropod related allergen accounted for 82.1% (78 patients) of the positive rate. 3. Each positive rate of Dermatophagoides farinae (Df), Dermatophagoides pteronyssinus (Dp), house dust (Hd), and cockroach mix (Cm) was 45.0% (72 patients), 43.1% (69 patients), 28.1% (45 patients), and 8.8% (14 patients), respectively. 4.Significant agreement between arthropod allergens was observer (P < 0.05). 5. The obseved agreement between Df and Dp was 95.6%, showing most significant Kappa index (Kappa = 0.911, P < 0.001). There results suggested that although MAST-CLA is a useful measure of identifying specific allergens, the specificity of two mite allergen relatively low, implying because of common allergen between mites in Korean panel of MAST-CLA. Our data also supported that arthropod is the major cause of allergen in patients with allergic rhinitis, however, the MAST-CLA should be modified in order to exclude common allergen of mite and to include more specific mite allergen.

The thesis deals with petrogenesis relating to environmental changes through emplacement of quartz monzonitic dikes distributed in the Apsan area in vicinity of Daegu, Korea. These dike rocks belongto monzonite series in the mineralogical composition. and their textures are characterized by a wide range of change from porphyritic at the border to more equigranular at the center portion of the dikes. The quartz monzonitic rocks are occurred as ring dikes around quartz monzonite stock exposed in southern portion of the study area. Throgh the consideration of the textural characteristics and crystallization process of the dike rocks, it is supposed that coarse grained plagioclase phenocrysts (about 8㎜ in diameter) might be already grown as almost present size during stoping at deeper level before the stage of uprising as ring dikes, and intermediate (about 3㎜) and fine (about 1㎜) grained phenocrysts might be nucleated and polymerized during development of conical joint and uprising of magma through the joints. In the viewpoint of plagioclase composition, An-content of the plagioclase phenocrysts decreases from border to center portion on several traverses that cross the dikes in different area, which reflects that marginal phase might be emplaced earlier than the inner phase and that degree of reaction between residual magma and plagioclase increases toward center owing to increasing diffusion rate. The continuous uprising of magma might be also revealed by the fact that tendency of accumulation of phenocrysts in central portion by flow differentiation according to crystal dispersive power in the dikes is not visible in the area. Thus, textural characteristics and composition of plagioclase of the dike rocks in the area, could be contributed as some indicators clarifying the process and mechanism of emplacement and environment of solidification of magma, especially the fact according to the important geological event which represents beginning of jointing and formation of dikes.

본 연구는 사춘기 성장 이전의 I, II급 부정교합을 갖는 아동 환자들의 측모 두부 규격 방사선사진을 이용하여 두개 안면 형태를 조사하고 이들과 혀의 위치 및 면적, 기도의 면적과의 관계를 조사하여 비인두 기도 및 혀의 형태가 악골 및 부정 교합의 형태에 미치는 영향을 알아보았다. 9 - 11세의 교정환자 76명을 대상으로 측모 두부 규격 방사선사진상 ANB difference를 기준으로 대조군(I급 부정교합군: 0 ≤ ANB difference < 4.0)과 실험군(II급 부정교합군: ANB difference ≥ 4.0)으로 분류하였다. 혀 면적, 혀와 구개 사이의 면적, 비인두 기도 면적과 두개안면형태 항목을 측정하고 비교하여 다음과 같은 결과를 얻었다. 혀 면적, 혀와 구개 사이의 면적, 비인두 기도 면적은 II급 부정교합군과 I급 부정교합군 간에 유의한 차이를 보이지 않았다. Hyperdivergent안면 형태일수록 비인두 기도 면적이 좁았다. 안모의 전후방 수직 길이가 길수록 혀의 면적이 넓었고, 전안면 고경이 길수록 혀는 하방위치 하였다. 비인두기도 면적이 좁을수록 혀의 면적도 좁아졌다. 이상의 연구 결과 혀의 면적과 위치, 비인두 기도의 면적은 I급, II급 부정교합 간에 차이를 보이지 않으며 hyperdivergent 안면 형태 및 안모의 전후방 수직 길이와 관련이 있는 것으로 사료된다. Objective: This study examined the craniofacial morphology of young patients in their prepubertal stage showing class I, II malocclusion, by analyzing lateral cephalograms, and analyzed its relationship with tongue position, tongue space, and airway space in order to ascertain the effects of nasopharyngeal airway and tongue morphology on the form of the malocclusion. Methods: Seventy-six patients aging from 9 to 11 were divided into two groups depending on the ANB difference on the lateral cephalogram: Experimental grouP (CI II malocclusion group) showing 0 ≤ ANB difference < 4.0; Control group (CI I malocclusion group) showing 0 ≤ ANB difference < 4.0. The tongue space, space between palate and tongue, nasopharyngeal airway space and craniofacial morphology were compared between the two groups. Results: Tongue space, Palate-tongue space, nasopharyngeal airway space showed no significant differences between class I and class II malocclusion groups. Hyperdivergent faces were associated with smaller nasopharyngeal airway space. Longer anterior facial height and posterior facial height were associated with larger tongue space, and greater anterior facial height were associated with lower tongue position, Smaller nasopharyngeal airway space showed smaller tongue space. Conclusions: Tongue space and nasopharyngeal airway space showed no significant differences between class I malocclusion group and class II malocclusion group. Only anterior facial height and posterior facial height had an influence on tongue space and nasopharyngeal airway space.

Effects of ferrite grain size and martensite volume fraction on quasi-static and dynamic deformation behavior of dual phase steels were investigated in this study. Dynamic torsional tests were conducted on six steel specimens, which had different ferrite grain size and martensite volume fraction, using a torsional Kolsky bar. Under a dynamic loading condition, maximum shear stress and fracture shear strain increased with decreasing the ferrite grain size and increasing the martensite volume fraction. Observation of the deformed area beneath fracture surface after the dynamic torsional test indicated that adiabatic shear bands of 5-15 μm in width were formed along the shear stress direction; voids or microcracks initiated at martensite/ferrite interfaces below the shear band. The width of the shear band decreased with increasing ferrite grain size and with decreasing martensite volume fraction. These phenomena were then analyzed by introducing concepts of critical shear strain. (Received April 7, 2004)

Among various methods for reducing the ground loss, this study introduces the pre-loading method which has been recently developed. Also, the major influence factos concidered fundamentlly in application of the pre-loading method are studied through hypothetical examples. In order to estimate the reduction effect of the ground loss by using the pre-loading method, three types of wall with the same ground conditions and the strut system have been considered. And each type of the walls has been clsssified again into twd categories depending on the rigidity of the temporary walls to invastigate the influence of wall rigidity on the reduction effect of ground loss owing to pre-loading in detail. The variation of underground water level has been evaluated by the seepage analysis. And the soil movement of the ground and axial force of struts in the back site of the excavation have been calculated by analyzing the soil behavior with the consideration of the underground water variation calculated by the seepage analysis. The reduced ground losses related to the magbitude of pre-loads have been determined by varying the pre-loads on the struts.
