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.

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.

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.

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.

Magnetic particles with alternating magnetic field are expected to be useful as thermoseeds in hyperthermic cancer treatment, since they can be targeted and confined to the cancer site. Hard magnetic ferrites such as barium ferrite and strontium ferrite are good candidates for thermoseeds of hyperthermia because of their great hysteresis loss. In order to verify the effect of Sr-substitution to Ba-site, synthesized Ba1-xSrxFe12O19 microspheres with various compositions through spray pyrolysis followed by sol synthesis using barium nitrate, strontium acetate and iron nitrate. Coercive force was increased with increasing substitution amount of Sr whereas magnetic saturation was almost constant. Spherical microspheres with average diameter of 11.7~17.0 ㎛ were produced by spray pyrolysis at 400~1000℃. The mean size was dependent on the pyrolysis temperature and flow rate of carrier gas. In order to obtain a single phase of SrFe12O19 crystal, the spray pyrolyzed spheres were undertaken subsequent heat-treatment above 1000℃. During the subsequent heat-treatment, however, spherical microspheres were agglomerated because of necking between particles. Further study has to be continued working on synthesis of pure SrFe12O19 crystal by means of improvement of pyrolysis temperature scheme and extend the heating period.
