1986年 2月부터 同年 5月까지 大邱近郊의 都市 및 農村國民學校 學童과 孤兒院生의 蟯蟲 感染率을 Graham氏 scotch-tape檢査法으로 1回 檢査한 다음 Choi等(1973)의 調査 成績과 比較하였다. 이번 調査(1986)에서 被檢兒動 936名 中 蟯蟲卵의 檢出率은 27.8%였고 男兒 26.0%, 女兒 29.6%로서 性別間에 有意的 差를 認定할 수 없었으며 年齡이 增加할수록 높았다. 都市兒童에서의 蟯蟲卵의 檢出率은 1973年 43.4%였던 것이 이번(1986)에는 5.4%로서 顯著하게 減少되었다. 그러나 農村學動과 孤兒院生에서는 그 率에 有意的 減少를 나타내었으나 顯著하지 않았다. From February to May, 1986, urban and rural school children and institution children were examined for the presence of Enterobius vermicularis eggs in the Taegu area. All children were examined once by a modification of the Graham's scotch-tape swab technique, and compared with the results reported by Choi et al. (1973). The detection rate in 936 children was found to be 27.8 per cent. The rate in boys was 26.0 per cent, and the rate in girls 29.6 per cent. There was no significant difference in the rate with regard to sex. But the rate among the urban school children in the present study(1986) was only 5.4 per cent, and markedly decreased as compared with the rate, 43.4 per cent reported by Choi et al. (1973). However, difference in the rate of infestation in both rural school children and institution children was not pronounced between 1973 and 1986.

Sun-youp Park,Jin Choi1,Jung Hyun Jo,Ju Young Son,Yung-Sik Park,Hong-Suh Yim,Hong-Suh Yim,Hong-Kyu Moon,Young-Ho Bae,Jang-Hyun Park 한국우주과학회 2015 Journal of Astronomy and Space Sciences Vol.32 No.3

An algorithm to automatically extract coordinate and time information from optical observation data of geostationary orbit satellites (GEO satellites) or geosynchronous orbit satellites (GOS satellites) is developed. The optical wide-field patrol system is capable of automatic observation using a pre-arranged schedule. Therefore, if this type of automatic analysis algorithm is available, daily unmanned monitoring of GEO satellites can be possible. For data acquisition for development, the COMS1 satellite was observed with 1-s exposure time and 1-m interval. The images were grouped and processed in terms of “action”, and each action was composed of six or nine successive images. First, a reference image with the best quality in one action was selected. Next, the rest of the images in the action were geometrically transformed to fit in the horizontal coordinate system (expressed in azimuthal angle and elevation) of the reference image. Then, these images were median-combined to retain only the possible non-moving GEO candidates. By reverting the coordinate transformation of the positions of these GEO satellite candidates, the final coordinates could be calculated.

Malaria is the world's most important parasitic infection. Although it has been erw5cated from temperate zones including Korea, increasing numbers of travellers visit tropical malarious countries and imported malaria becomes important medical problem in the developed countries. In Korea with increasing travellers to malaria-endemic area, the incidence of imported malaria shows rising tendency same as the developed countries. It becomes important to personal general personal protective measures and chemoprophylaxis to trevellers, when employed in appropriate manner, that can be highly effective in preventing malaria. We recently experienced a case of in Plasmodium vivax malaria with delayed manifestations due to inadequate chemoprophylaxis. A 53-year-old woman with history of trevel to East Africa 4 months ago and chief complaint of fever was diagnosed as tertian malaria. She had irregularly taken prophylatic antimalarial during travel and had not taken it after return but should have taken it at least 4 weeks after return.

치면열구전색제 도포 후 시간에 따른 열구 내 침투율을 알아보고자 발치된 소구치 192개를 이용하여 전색제 도포 후 광중합 할 때까지 경과시간 3초, 5초, 10초, 20초별로 침투율을 비교 분석하였다. 여기에 추가적으로 상악과 하악, filled sealant와 unfilled sealant군으로 나누어 시간대별로 침투율에 차이가 있는지도 비교분석하였다. 그 결과 시간이 경과할수록, filled sealant군보다 unfilled sealant군에서, 상악보다는 하악에서 전색제의 침투율이 증가하였다. 이상의 결과에서 임상에서 치면열구전색을 시행할 때 이 결과를 임상적 지침으로 적용하면 유용하리라고 여겨진다. Occlusal fissures and pits are ideal places for the development of caries. Pit and fissure sealants are now considered as a very effective means to prevent dental caries. The purpose of this investigation was to examine the effect on the sealant penetration of the elapse of time from the application of sealant until exposure to visible light, and to examine the effect of the filler content and tooth position on the sealant penetration. 192 extracted human premolars were used to this experiment. Following enamel conditioning, a light-polymerized sealant was applied and 4 different periods of time(3, 5, 10, 20 seconds) were allowed until exposure to the light source. The results obtained were as follows: 1. According to time, in both unfilled sealant and filled sealant penetration increases deeply through mindfulness. 2. Sealant that apply to mandiblar premolar penetrated deeply through than to maxillay teeth. 3. Penetration difference according to filler content, unfilled sealant penetrated deeply through than filled sealant. The result from this study indicated that unfilled sealant penetrated most deeply in mandible when at least 20s time elapsed.

Hepatocellular carcinoma(HCC)is one of common causes of cancer-related death in Korea where the majority of HCC patients were Hepaitc B virus(HBV)carriers and have cirrhosis. Transarterial chemoembolization(TACE)is commonly applied to the treatment of multinodular HCC in Korea and careful selection of candidate is important for the risk of various side effects. Besides common side effects as fever, nausea, abdominal pain and elevation of liver enzyme, TACE may predispose to hepatic failure, ischemic cholecystitis, pulmonary embolism, cerebral embolism and pneumonitis. In previous studies, some cases of pulmonary and cerebral embolism cases were reported but lipiodol pneumonitis after TACE was rarely reported. A 65-year-old woman with a multinodular HCC associated with HBV infection, was treated with TACE. Seven days after the procedure, nonspecific respiratory symptoms such as dyspnea and dry cough developed. Chest X-ray and chest computed tomography showed diffuse ground glass opacities in whole lung fields, suggestive of lipiodol pneumonitis. After several days of supportive care with steroid administration, radiologic abnormalities and subjective symptoms were much improved, considered that the disease was compatible with lipiodol pneumonitis.

Background/Aims: The most commonly used immunosuppressant therapy after liver transplantation (LT) is a combination of tacrolimus and steroid. Basiliximab induction has recently been introduced; however, the most appropriate immunosuppression for hepatocellular carcinoma (HCC) patients after LT is still debated. Methods: Ninety-three LT recipients with HCC who took tacrolimus and steroids as major immunosuppressants were included. Induction with basiliximab was implemented in 43 patients (46.2%). Mycophenolate mofetil (MMF) was added to reduce the tacrolimus dosage (n=28, 30.1%). The 1-year tacrolimus exposure level was 7.2 ± 1.3 ng/mL (mean ± SD). Results: The 1- and 3-year recurrence rates of HCC were 12.9% and 19.4%, respectively. Tacrolimus exposure, cumulative steroid dosages, and MMF dosages had no impact on HCC recurrence. Induction therapy with basiliximab, high alpha fetoprotein (AFP; >400 ng/mL) and protein induced by vitamin K absence/antagonist-II (PIVKA-II; >100 mAU/mL) levels, and microvascular invasion were significant risk factors for 1-year recurrence (P<0.05). High AFP and PIVKA-II levels, and positive 18fluoro-2-deoxy-d-glucose positron-emission tomography findings were significantly associated with 3-year recurrence (P<0.05). Conclusions: Induction therapy with basiliximab, a strong immunosuppressant, may have a negative impact with respect to early HCC recurrence (i.e., within 1 year) in high-risk patients.
