Modernism Architecture in international style has made new spatial paradigm using steel and glass until 1900s. This paradigm influenced in indoor space was shown to Works of four great masters, Mies van der rohe, Le Corbusier, Aalvar alto, Frank L. Wright, and some characteristics are found in four great masters' works in common. These characteristics are simplicity of spatial form, usefulness and functionality of design, openness of indoor space, Total design, internal and external interpenetration. These are shown in interior space of Korea modern architecture as changing their conditions. This study drives at what major characteristics changes the way of proper transformation and adaption in two modern architect of Korea, Kim Swoogeun and Kim Chungup as according to modern architecture principals. Some controlling principles are found out in their works, and the ways of transformation and adaption are analogy with its special occasion of Korea.

These days, bridges have a tendency to be long-spanned and simple ‘ thus, the importance of economy and efficiency has increased for bridge construction. As a result, one of the main members on which interest is focused is the diaphragms. In this study, stress variation of the support diaphragms in a steel box girder was considered. This paper deals with the behavior of the stress distribution on the diaphragms on the bearings of a closed section steel box girder bridge due to the continuous casting of concrete slab. Both experimental and structural analyses were performed to verify the behavior of the stress distribution a composite steel box girder bridge under construction. Strain was continuously checked at intervals of 10 to 30 min. from the beginning of the placement by the Time Interval Function of the measuring instrument. The variation of strain on the diaphragms on the bearings are presented herein.

Hypoparathyroidism is usually the result of an inadvertent surgical removal of all the parathyroid glands, In some instances, not all the tissues are removed, but the remainder undergoes vascular supply compromise secondary to the fibrotic changes in the neck after surgery, Previously, the surgery for hyperthyroidism was the most frequent cause of acquired hypoparathyroidism. Idiopathic hypoparathyroidism is a relatively rare disease that is characterized by hypocalcemia and hyperphosphatemia due to a parathyroid hormone deficiency of an unknown cause, It usually develops at a young age, and shows various clinical symptoms and signs accompanied with hypocalcemia. In addition, it is rarely associated with polyglandular autoimmune syndrome during the follow-up. Hypocalcemia and idiopathic hypoparathyroidism associated with labor and lactation are rarely reported condition previously. We here describe a case of a woman in whom the symptomatic severe hypocalcemia appeared after her delivery. We reviewed all the previously reported cases and suggest a possible physiological explanation for the association between pregnancy, lactation, and the appearance of symptomatic hypocalcemia.

The purpose of this study was the reaching test of restorative glass according to composition. Mixtures of SrF₂, CaF₂and SiO₂were fused in platinum crucible. The glasses were ground and fraction which passed through a 400 mesh (38㎛) sieve were collected. The powder specimens were analyzed by a DTA and XRD. Then powder specimen were inserted to D. I. water with various of dissolution time and composition at 37℃. Fluoride ion, cation release, solubility, and pH change were estimated. It was clear that the glasses were formed except S0.65. In S0.40, Tg, Ts, and Tc were 630, 672, and 813℃ respectively. In initial 0.5 hrs., amounts of released fluoride ion and cation were about 90% of total released amounts and released rate was decreased with dissolution time. Amount of released fluoride ion and cation were increased with decreasing SiO₂ in glass filler. And released rate was decreased rapidly by adding CaF₂. This was caused by structural variation in glass filler. Solubility was similar tendency with ion released. The pH of D.I. water was 4.5. But in intial 0.5 hrs., pH was 8.2∼9.8., and decreased according to dissolution time. This is caused by ionic changing with cation and H* ion.

Toxoplasmosis is a rare but fatal complication in hematopoietic stem cell transplant recipients, usually associated with allogeneic hematopoietic stem cell transplantation (HSCT). We report a case of cerebral toxoplasmosis in a patient with multiple myeloma, following tandem autologous stem cell transplantation. A 55-year-old Korean male presented with weakness in both legs that had progressed to both arms. A magnetic resonance imaging scan of the brain revealed multiple, variablesized ring-enhancing lesions with surrounding edema in the cerebral hemispheres and brain stem. Stereotactic biopsy revealed bradyzoites of Toxoplasma gondii in the brain tissue. The patient received trimethoprim-sulfamethoxazole, followed by pyrimethamine and sulfadiazine, accompanying treatment for progressive multiple myeloma. Cerebral toxoplasmosis should be considered as one of the differential diagnoses in patients with neurologic signs following autologous HSCT.

Good 증후군은 흉선종과 면역결핍이 동반되는 질환으로, B세포의 감소로 인한 범저감마글로불린혈증과 CD4^(+)T세포의 감소로 인한 세포성 면역저하가 동시에 나타나는 것을 특징으로 한다. 본 증례는 18개월 전부터 발생한 반복적인 부비동염을 주소로 내원한 43세 남자 환자로, 내원 1년 전 흉선종절제수술을 시행받았으며, 면역학적 검사상 범저감마글로불린혈증과 T세포의 감소 등의 이상 소견이 발견되었다. 정주 면역글로불린과 경험적 항생제(amoxicillin/clavulanic acid) 사용 후 부비동염이 호전되었으며, 예방접종과 정기적인 면역글로불린 투여 후 특이 합병증없이 경과 관찰 중이다. Good's syndrome is the association of thymoma with immunodeficiency, characterized by hypogammaglobulinemia, B-cell lymphopenia and variably defects in cellular immunity with CD4^(+) T-cell lymphopenia and an inverted CD4^(+):CD8^(+) T-cell ratio. We report a 43-year-old male patient who presented with a 18-month history of productive cough and postnasal drip. One year ago, he underwent the operation for resection of a thymoma. Despite of appropriate management, sinusitis relapsed multiple times. He was found to have hypogammaglobulinemia with nearly absent B cells(4/μL). The CD4^(+) T-cell count was 554/μL with an inverted CD4^(+):CD8^(+) T-cell ratio of 0.6. His symptoms and signs improved with antibiotic treatment and monthly administration of intravenous immunoglobulin (IVIG, 400 mg/kg).

The armillary sphere, an astronomical observation device embodying the Orbital Heaven Theory of the Later Han Dynasty in China, holds both historical and scientific significance. It has been produced in various forms by many individuals since its inception in the era of King Sejong in the Joseon Dynasty. A prominent figure in this field was Nam Byeong-cheol (南秉哲, 1817-1863), known for his work 'Uigijipseol' (儀器輯說), published in 1859, which detailed the history, production methods, and usage of the armillary sphere. This text particularly highlights 21 applications of the armillary sphere, divided into 33 measurements, covering aspects like installation, time, and positional measurements, supplemented with explanations of spherical trigonometry. Despite numerous records of the armillary sphere's design during the Joseon Dynasty, detailed usage information remains scarce. In this study, the 33 measurements described in 'Uigijipseol' (儀器輯說) were systematically classified into six for installation, nineteen for position measurement, seven for time measurement, and one for other purposes. Additionally, the measurement methods were analyzed and organized by dividing them into the ecliptic ring, moving equatorial ring, and fixed equatorial ring of the armillary sphere. In other words, from a modern astronomical perspective, the results of schematization for each step were presented by analyzing it from the viewpoint of longitude, right ascension, and solar time. Through the analysis of Nam's armillary sphere, this study not only aims to validate the restoration model of the armillary sphere but also suggests the potential for its use in basic astronomical education based on the understanding of the 19th-century Joseon armillary sphere.

The molding technique of dental ceramics are very important. Because dental ceramics are purchased with powder state, they must be mixed with adhesive liquids or water for plasticized materials. The procedures to mix with liquids, condense and build up were very careful and mechanical properties of dental ceramics were closely related with them. If it will be possible to use of light curing liquids, molding procedures will be easier than using water. To evaluate the physical properties of dental ceramics using light curing molding liquids, light curing liquids were made with triethylene glycol dimethacrylate(balance), camphoroquinone(1%) and ethyldimethylaminobenzoate(1%) and one type of dental ceramics(Ceradent, Ssangyong Co., Taegu, Korea) was chosen(A3 dentin). The specimens were formed in mold(25×5×3㎜) using light curing liquid for experimental group(LC) and using distilled water for control group(CO). LC were light cured and air-fired for elimination of organic materials and CO were vacuum fired. Sintering shrinkage was measured by measuring microscope(Measuroscope Ⅱ, Nikon Co., Tokyo, Japan), 3-point flexural strength was measured by universal testing machine(Instron 6022, Instron Co., High Wycomb, U.K.), and color was measured according to CIEL*a*b* system by spectrophotometer(Minolta 3500D, Minolta Co., Osaka, Japan). The results were analyzed by Wilcoxon Rank Sum Test. Sintering shrinkage and flexural strength of LC lower than CO(p<0.5). But they were acceptable to standards of ISO specification : 6872. L*, a* values of LC had higher than those of CO(p<0.5), but b* value of LC had no significance compared with CO(p>0.5) and ΔE was 26.7. The application of light curing liquids for molding liquids of dental ceramics was considerable, especially core materials, because of color changes.

Compomer materials have the advantages of glass-ionomer cements and similar physical properties of composite resins. But there were a few studies about the color stability of compomers. In this study, two commercial compomers, Dyract and F2000, and two composite resins, Estelite and Z100, were used. They were stored in 37℃ water bath for 1 week and in 60℃ water bath for another 1 week and then they were aged with 150k1x xenon lamp for 1 week and another 1 week. The original colors just after light cured as the control color were measured by a spectrophotometer according to the C.I.E. L*a*b* Systems, and the colors stored in 60℃ water bath for 1 week, the colors aged with xenon lamp for 1 week in dry and wet condition, the color aged with xenon lamp for 2 weeks in dry and wet condition, were measured by the same method and compared with the control color. The results were as follows. The □E values of dyract after water bath storage and xenon lamp aging were over 10, and the □E values of F2000 after xenon lamp aging were 3.3-6.35. and the □E values of Z100 after xenon lamp aging were 3.3-5.23, and there were not ? E values of Estelite over 3.3 When the thickness of specimen increased the L*, a*, b* values of all material except Dyract were significantly increased(P<0.05), and Compared with dry condition, the L* values were significantly reduced, and the b* values were significantly increased in wet condition(P<0.05). It was concluded that Dyract compomer was not acceptable for and esthetic restorative material in permanent teeth for the color changes were over 10, and F2000 compomer had the color stability similar to the Z100 composite resin.
