ABSTRACTThis study was aimed to evaluate the changes in condylar position when severe anterior open bite pa- tients were treated with MEAW.The subjects consisted of 11 patients(21 TMJs) who visited the departement of orthodontics in SNUH, having severe anterior open bite as a chief complain. They were supposed to wear the up and down elas- tics and MEAW after finishing the leveling. The condylar position was evaluated with individualized cor- rected tomography in centric occlusion taken before and after treatment.The results were as follows; 1. In the change of condylar position after treatment, there were no statistically significant differences in right and left TMJs. 2. In the change of condylar position after treatment, there were no statistically significant differences in each malocclusion groups. 3. There were no statistically significant differences in percent dispacement of condyle between before and after treatment. 4. There were no statistically significant differences in the amount of change in condylar change.

Study Design : The authors retrospectively analysed the recovery of clinical symptoms after surgical treatment of lumbar HIVD. Objectives : To investigate the incidence of clinical symptoms, the recovery rate and time after surgical treatment and the difference between L4-5 and L5-S1 lesion. Summary of Literature Review : There are many reports concerning the clinical result of surgical treatment for the HIVD. They usually describe the result as excellent, good, fair and poor. We can't get any information about the recovery rate and recovery time of each clinical symptom from the reports. Materials and Methods : Thirty-eight patients were treated by one level open discectomy from march 1991 to december 1995. The clinical symptoms and signs including SLR, motor deficit, sensory deficit, change of DTR and severity of radiating pain were periodically followed up on the predesigned protocol, Results : In preoperative examination, SLR was positive in 82%, motor deficit in 76%, sensory deficit in 74%, DTR change in 50%, and radiating pain in 100%. The recovery rate of SLR was 96.8%, motor deficit ; 93.6%, sensory deficit ; 78.6%, DTR change ; 21 % and radiating pain ; 84.2%. The average recovery time of SLR was 3.4 months, motor deficit ; 1.9 months, sensory deficit ; 5.3 months, DTR change ; 4.1 months and radiating pain ; 3.2 months. Motor and sensory deficit was more frequent in L4-5 lesion but DTR change was usually noted in L5-S] lesion. The recovery rate and time showed no great difference between the two level. Conclusions : The recovery rate was higher in SLR, motor deficit and radiating pain rather than sensory deficit and DTR change. The recovery time was fastest in radiating pain but variable nature was noted in sensory deficit. Above results may be helpful to explain the prognosis of the lumbar HIVD.

Background: Epidermal cysts (EC) are the most common tumors found on the skin and accompanying inflammation is also frequent. However, the predictors for inflammatory change have not been investigated yet. Objectives: This study was performed to investigate the difference between inflamed and uninflamed epidermal cysts, and to assess associated factors for inflammatory change. Methods: We analyzed the biopsy-proven 1723 epidermal cysts (515 inflamed and 1208 uninflamed) at two tertiary hospitals from 2011 to 2021. Results: The proportion of inflamed epidermal cysts (IEC) and uninflamed epidermal cyst (UIEC) were 29.9 % and 70.1 %, respectively. Inflammatory change was less frequently observed on the face (25.5 %) than the other sites (32.1 %) (p=0.0046). The anatomic location with the highest rate of inflammatory change was back (40.8 %, p=0.0004). Mean duration of inflammatory change from UIEC to IEC on the face was shorter than the other sites (12.5 months vs 17.9 months, respectively, p= 0.0473). On ultrasonography, long axis of IEC (20.7mm) was generally longer than that of UIEC (15.7mm) (p=0.0218). Moreover, Inflammatory change was more frequent on the EC with punctum compared to those without punctum (35.3 % vs 30.3 %, P=0.0471). Conclusion: Based on the location, size and presence of punctum, decision on the optimal treatment strategies can be established when encountering patients with EC.

Background: Subclinical hypothyroidism(SCH) is a common biochemical abnormality which can be found in routine screening tests of thyroid function. We are increasingly faced with the question of whether its an indication for thyroxine replacement therapy. The effect of thyroxine replacement on lipid profile in SCH has aroused a great interest because of an association of overt hypothyroidism(OVH) with hyperlipidemia and increased risk of coronary artery disease. Method: We prospectively evaluated the changes in lipids and apoproteins before and after thyroxine replacement therapy in 23 patients with SCH and in 37 patients with OVH. We measured serum total cholesterol and triglyceride using autoanalyzer, high density lipoprotein(HDL) chole-sterol by dextran sulfate method, Apo A1 and Apo B by immunonephelometric assay. Results: Thyroxine replacement therapy significantly decreased total cholesterol, low density lipoprotein(LDL) cholesterol and apo B levels, but did not affect the level of triglyceride, HDL cholesterol or apo AI in patients with OVH. In SCH, thyroxine replacement therapy with the doses to normalize serum TSH concentrations also decreased significantly the level of cholesterol and LDL cholesterol albeit apo B levels did not change. Moreover, in most of patients with OVH (11 of 12) and in all of patients with SCH(5 of 5) who had had hyperchlesterolemia before treatment, thyroxine replament normalized their cholesterol and LDL cholesterol levels. Conclusion: In regard to the beneficial changes in blood lipid levels, patients with SCH should be treated, especially in cases who have other risk factors for the development of atherosclerosis. If thyroxine replacement only will reduce the incidence of coronary artery disease in SCH remains to be elucidated by long-term prospective studies(J Kor Soc Endocrinol 11:41-51, 1996).

Cutaneous angioleiomyomas are benign tumors with vascular smooth muscle differentiation. The tumor usually involves the lower extremity, but acral sites such as toes, fingers, feet, and hands are rarely affected. Leiomyoma of deep soft tissue commonly shows regressive changes including prominent fibrosis, and calcification, however, cutaneous angioleiomyoma rarely manifests these changes. A 61-year-old female presented with subcutaneous nodule on the right heel. The lesion began to develop 3 months ago without history of trauma or infection, and the patient reported no subjective symptom. The lesion was totally excised, and histopathology revealed a well-circumscribed, non-encapsulated tumor composed of interlacing fascicles of spindled cells with elongated blunt-ended nuclei. A major finding was extensive calcifications, which dominated over the cellular component. On immunohistochemical examination, the spindle cells expressed strong immunoreactivity for α -smooth muscle actin. Based on these findings, a diagnosis of acral calcified angioleiomyoma was made. We have described a rare clinicopathologic variant of angioleiomyoma which has a predilection for acral locations and shows extensive calcifications predominating over the tumor itself. To our knowledge, this is the first report of a patient with acral calcified angioleiomyoma in Korean dermatologic literature.

Surface albedo from the geostationary Communication, Ocean and Meteorological Satellite (COMS)/Meteorological Imager (MI) observation system

Lee, Chang Suk,Han, Kyung-Soo,Yeom, Jong-Min,Lee, Kyeong-sang,Seo, Minji,Hong, Jinkyu,Hong, Je-Woo,Lee, Keunmin,Shin, Jinho,Shin, In-Chul,Chun, Junghwa,Roujean, Jean-Louis Informa UK (TaylorFrancis) 2018 GISCIENCE AND REMOTE SENSING Vol.55 No.1

<P>The surface albedo is an essential climate variable that is considered in many applications used for predicting climate and understanding the mechanisms of climate change. In this study, surface albedo was estimated using a bidirectional reflectance distribution function model based on Communication, Ocean and Meteorological Satellite/Meteorological Imager data. Geostationary orbiting satellite data are suitable for a level 2 product like albedo, which requires a synthetic process to estimate. The authors modified established methods to consider the geometry of the solar-surface-sensor of COMS/MI. Of note, the viewing zenith angle term was removed from the kernel integration used for estimating spectral albedo. Finally, the spectral (narrow) albedo was converted into the broadband albedo with shortwave length (approximately 0.3-2.5 m). This study determined conversion coefficients using only one spectral albedo of visible channel. The estimated albedo had a relatively high correlation with Satellite Pour l'Observation de la Terre/Vegetation and low unweighted error values specific for land types or times. The validation results show that estimated albedo has a root mean square error of 0.0134 at Jeju flux site that indicates accuracy similar to that of other satellite-based products.</P>

인위적인 기후 변화를 유발하는 이산화탄소 배출량을 줄이기 위해 제로에너지 건축이 법제화 되었으나, 종래의 건물 일체형 태양광 모듈은 태양광 발전 효율을 최대화하기 위해 흑색으로만 제작되었기에 심미성을 중요시하는 건축물의 외관에 적용하는데 장애물이 되어왔다. 본 연구에서는 마이크로-플레이트릿 광간섭 안료를 이용한 태양광용 고투과 컬러 유리의 제작에 대해 소개하도록 한다. 광간섭 안료의 함량이 광학 투과율에 미치는 영향을 조사함으로써 색상을 구현하는데 요구되는 광간섭 안료의 최소 함량을 결정하였다. 3wt% 광간섭 안료 함량의 컬러 유리로 태양광 모듈을 제조하고 전기적 특성을 측정하였다. 마이크로-플레이트릿 광간섭 안료의 사용은 진공 증착 다층 박막 적층법으로 색상을 구현하는 방식보다 저렴한 인쇄 공정을 적용할 수 있기 때문에 제조 비용을 절감할 수 있으며, 발전 효율도 기존 태양광 모듈의 76.15%에 이르렀다. The construction of zero-energy buildings will become mandatory to curtail the amount of CO₂ emissions, which lead to anthropogenic climate changes. However, conventional building-integrated photovoltaics are monotonously black in color to ensure high photoconversion efficiency. Hence, this has been a hurdle in aesthetically decorating the skin of a building. In this study, a micro-platelet light-interference pigment is explored for the fabrication of a highly transparent color glass for photovoltaic applications. The impact of pigment concentration on optical transmittance is investigated and the minimum pigment concentration for realizing a vivid color is determined. A photovoltaic module is fabricated using a color glass with a pigment concentration of 3 wt%, and its electrical properties are measured. The use of a micro-platelet light-interference pigment lowers the fabrication cost (by using a printing process) when compared to that of a costly color glass with multi-layered thin films deposited in vacuum. Furthermore, the relative photoconversion efficiency of the proposed method when compared to a conventional photovoltaic module is as high as 76.15 %.
