Cd_1-xMn_xTe single crystals were grown by vertical Bridgman method and Mn mole fraction x was determined by the X-ray diffraction. Band gap and optical transition energies E₁, E₁+ △₁, E₂, △₁as Mn mole fraction x were obtained by measuring optical absorption and reflection at UV-visible region respectively. The change of the valence band spin-orbit splitting △₁at △ point of the Brillouin zone was discussed.

This study was conducted for the purpose of suggestion of the new technique of sagittal split ramus osteotomy pararell to the true sagittal plane. This pararellism is the important concept of the sagittal split ramus osteotomy to reduce the condylar sagging including mandibular hypomobility, tempormandibular disorder, occlusal relapse and other complications. We used 26 adult dry manibles(52 rami), and obtained the computed tomographs through the sagittal, horizontal and coronal sections. The results were obtained as follows. 1. On sagittal section, mean area of S1 was 8.63±2.10㎠, S2 was 8.93±1.94㎠, S3 was 9.49±2.15㎠, S6 was 10.72±2.22㎠. The wider area of sagittal section, the more lateral section, But, no singnificant differency between the areas of the sagittal sections(P>0.05). 2. On horizontal section, The distance between the inferior alveolar canal and the lateral cortical plate of the mandibular ramus were 6.73±1.24mm minum, 7.70±1.44mm maximum. 3. On coronal section, Outer mandibular angle were 4.84±2.37˚right side, 4.93±2.12˚left side. 4. The design of the ideal true sagittal split ramus osteotomy is that posterior border of osteotomy must be limited vertically, at the right posterior point of lingula mandibularis and anterior of osteotomy must be extended to mandibular body, anteroinferiorly.

Background and Objective: Mechanical laundry has a key role for environmental control of allergens. However, the optimal conditions for removing allergens such as house dust mite (HDM), dog dander, and pollens are not yet clear. Method: Four cleaning modes such as 30℃, 40℃, 60℃, and steam (adapt steam and water cleaning) were evaluated. Viability of HDM was assayed with heat escape method and levels of group 1 major allergens of D. farinae (Der f 1) and dog dander (Can f 1) were assayed with 2-site ELISA. Levels of pollen protein were assayed with Bradford method. Result: At 60℃ and steam cleaning modes, all HDM were dead but at 30∼40℃ modes, only 6.4∼9.3% of HDM were dead. The levels of Der f 1 in extraction buffers immediately after 30℃, 40℃, 60℃, and steam cleaning were 26.8%, 2.4%, 1.3%, and 0.6%, respectively. The levels of Can f 1 were 41.5%, 42.7%, 12.6%, 9.8% and the pollen protein levels were 31.8%, 4.9%, 3.9%, and 2.8%, respectively. Conclusion: Steam and 60℃ cleaning is better than 30∼40℃ cleaning for removing indoor and pollen allergens. (Korean J Asthma Allergy Clin Immunol 2006;26:289-296)

Objective: To compare the use of 3D driven equilibrium (DRIVE) imaging with 3D balanced fast field echo (bFFE) imaging in the assessment of the anatomic structures of the internal auditory canal (IAC) and inner ear at 3 Tesla (T). Materials and Methods: Thirty ears of 15 subjects (7 men and 8 women; age range, 22 71 years; average age, 50 years) without evidence of ear problems were examined on a whole-body 3T MR scanner with both 3D DRIVE and 3D bFFE sequences by using an 8-channel sensitivity encoding (SENSE) head coil. Two neuroradiologists reviewed both MR images with particular attention to the visibility of the anatomic structures, including four branches of the cranial nerves within the IAC, anatomic structures of the cochlea, vestibule, and three semicircular canals. Results: Although both techniques provided images of relatively good quality, the 3D DRIVE sequence was somewhat superior to the 3D bFFE sequence. The discrepancies were more prominent for the basal turn of the cochlea, vestibule, and all semicircular canals, and were thought to be attributed to the presence of greater magnetic susceptibility artifacts inherent to gradient-echo techniques such as bFFE. Conclusion: Because of higher image quality and less susceptibility artifacts, we highly recommend the employment of 3D DRIVE imaging as the MR imaging choice for the IAC and inner ear.

Primary biliary cirrhosis is a chronic, progressive liver disease characterized by inflammatory destruction of septal and intralobular bile ducts which results in intrahepatic cholestasis. Although the cause remains obscure, it is frequently associated with a variety of disorders presumed to be autoimmune in nature. We report a case of early primary biliary cirrhosis which was anteceded by rheumatoid arthritis. The patient was a 54-year-old female who was admitted due to arthralgia and joint deformity. She had been diagnosed as having rheumatoid arthritis 10 years before. On admission, she had elevated serum ALT, AST, alkaline phosphatase, gamma-GTP and positive serum antimitochondrial antibody test. Microscopic findings of the liver were consistent with the early stage of primary biliary cirrhosis.

1인 가구의 수가 지속적으로 증가하고, 소비자들이 자신만의 주거환경을 조성하려는 욕구가 커지면서 전통적으로 내구재로만 여겨졌던 가구의 제품수명주기는 짧아지고 홈퍼니싱 제품에 대한 소비는 확산되고 있다. 글로벌 홈퍼니싱 브랜드 이케아의 국내 진출로 인해 국내 가구브랜드들 역시 가정용 가구뿐 아니라 인테리어 소품, 잡화 등의 제품들을 종합적으로 제공하는 홈퍼니싱 업체로의 변화를 모색하고 있다. 본 연구는 이케아와 국내 가구브랜드 중 종합 홈퍼니싱을 제공하는 국내 주요 브랜드의 입지 정보를 이용하여 이케아의 매출액을 추정하는 모형을 구현한다. 브랜드마다 각기 다른 가격과 제품전략을 구현하고 있음을 감안하여 브랜드 선호도를 매장에 대한 매력도에 반영하고, 각 매장이 특정 위치에 입지하면서 누릴 수 있는 부가효과, 집적효과, 백화점 효과 등을 확률론적 입지모형인 Huff 모형에 반영하여 실제적인 매출액 추정이 가능한 모형을 구현한다. 본 연구는 국내 가구산업이나 홈퍼니싱 산업에서의 입지모형을 통해 매출액을 추정하고자 한 유일한 연구라는 점에서 의의가 있으며, 향후 순차적 입지를 계획하는 홈퍼니싱 브랜드나 매장전략의 변화를 모색하는 브랜드에게 실질적으로 도움을 줄 수 있을 것으로 기대된다. The main purpose of this paper is to develop the model for estimating the sales of a furnish retailer in which booming home-furnishing market in Korea. The proposed model is based on a probabilistic retail gravity model, and both the geographical characteristics and the potential customers’characteristics are also incorporated. Besides traditional components, such as the size of the facilities and the distance from the consumers to the facilities in the probabilistic retail gravity models, additive effects, clustering effects, and shopping center effects are considered as the geographical characteristics, and brand preference is considered as potential customers’characteristics. Such new factors enhance accuracy of the model that reflects the probability of consumers travelling from home to facilities. Ultimately, in order to estimate the sales of a facility, the ratio of one-person homes and the income level in each potential region are utilized. This study is meaningful in the fact that it is the only study to estimate sales in the domestic home-furnishing market, even though the market is restricted by furniture-based brands. It would be beneficial to the home-furnishing brands that seek to transform the store strategy as well as plan to implement the sequential location strategy.
