The purpose of this study is to develop models and instruments for teaching and assessing scientific experiments and practices. General objectives for teaching and evaluating scientific experiments and practices in secondary schools were analyzed and categorized into three domains:they were inquiry skill, scientific thinking skill, and scientific attitude. The sub-categories for each domain were constructed, and specific objectives for each general objective were also stated in terms of behavioral objectives according to Mager's suggestion. The tables of specification (content×behavior) were developed in order to assist secondary school teachers to teach and evaluate scientific experiments in class. In addition, we introduced some useful assessment techniques which can be adopted to evaluating learning outcomes of each specific objective. The sample test items corresponding to each objective were listed for practical usage in class.

Objective : This retrospective study was aimed to correlate characteristic neurologic deficits of transient contralateral motor weakness with or without speech disturbance(Supplementary Motor Area, SMA syndrome) after the resection of the gliomas in the superior frontal gyrus, especially with the extent of resection of the tumors. Method : Ten patients with medial superior frontal glioma, who underwent gross total or subtotal resection of the tumor, as well as, partial or complete resection of the spolementary motor area were studied. The following parameters were evaluate 1) tumor location 2) extent of resection 3) degree and duration of postoperative deficits. Result : Postoperative neurologic deficits were transient contralateral motor weakness with or without motor dysphasia. As a whole, postsurgical SMA syndrome occurred in 3 patients out of 10 patients with medial superior frontal gliomas(30%), who underwent gross total or subtotal resection of the tumors. Motor deficits were present in 3 out of 10 patients and speech disturbances in 2 out of 3 left frontal gliomas. Recovery of neurological dysfunction was rapid occurring between the 5th 14th POD and their neurological function returned almost normal in two patients. In the remaining one patient, who had preoperative mild motor weakness showed incomplete recovery of the worsened motor weakness and newly developed speech disturbance till 1yr postoperatively. Conclusion : The postsurgical SMA syndrome in patients with glioma in the medial superior frontal gyrus was not so uncommon phenomenon and well correlated with the extent of surgical resection of the supplementary motor area. Thus, preoperative awareness and warning about the possibility of the development of this charicteristic SMA syndrome is necessary.

지하공동구 화재 실험 및 시뮬레이션에 의한 화재 실험 예측 평가

윤명오,고재선,박형주,박성은 한국화재소방학회 2001 한국화재소방학회논문지 Vol.15 No.1

지하공동구는 최근 통신의 발달로 인해 국가 중추기능으로서의 주요 역할를 하는 시설로, 사고시 신속한 대처가 힘들고 케이블 연소시 발생하는 유독가스에 의한 검은 연기로 공동구 내에 진입하여 소화하기가 힘들다. 따라서 화재발생시 막대한 재산피해 및 통신의 두절 등 국가의 중추신경이 마비됨은 물론 시민 불편사항을 초래시켰다. 본 논문은 지금까지 발생되어온 공동구 화재를 바탕으로 실제 공동구 모형을 제작하여 화재를 재현함으로서, 과학적으로 화재의 성상을 분석하고 지하공동구 내에 소방설비를 갖춘 후에 일정온도에서 각각의 소방설비들이 제대로 작동하는지를 검증하는데 그 목적이 있다. 화재실험은 지하공동구 내에 정온식 감지선형 감지기, 방화문, 연결살수설비 및 환기설비를 설치하고 송 · 배전케이블은 일정구간 내화도료로 도장하며 난방관은 내화피복된 상태에서 실험하였다. 그 결과 최고 온도가 932℃로 측정되었고 일정온도에서 정온식 감지선형 감지기가 작동하여 화재위치를 정확히 수신반에 나타내었다. 그리고 송 · 배선케이블은 일정구간 내화도료로 도장한 것은 내화성능이 없는 것으로 나타났고, 내화피복된 난방관은 약 30분 정도의 내화 성능이 있는 것으로 나타났다. 컴퓨터 화재 시뮬레이션은 실제 화재 시험시의화재하중을 입력하여 실시한 결과 최고 온도가 943℃로 실제 화재시의 최고 온도인 932℃와 거의 일치하였다. 따라서 공동구 화재하중만으로 화재 시뮬레이션을 실시하여 화재의 성상에 대한 예측이 가능한 것으로 판단되며 시뮬레이션으로 얻는 열방출량, 연기층의 높이, 산소, 일산화탄소, 이산화탄소의 농도 등의 결과 값들을 실제 화재 실험시의 값으로 적용시킬 수 있는 것으로 판단된다. The utility tunnels are the important facility as a mainstay of country because of the latest communication developments. However, the utilities tunnel is difficult to deal with in case of a fire accident. When a cable burns, the black smoke containing poisonous gas will be produced. This black smoke goes into the tunnel, and makes it difficult to extinguish the fire, Therefore, when there was fire in the utility tunnel, the central nerves of the country had been paralyzed, such as property damage, communication interruption, in addition to inconvenience for people. This paper is based on the fire occurred in the utilities tunnel in the past, and reenacting the fire by making the real utilities tunnel model. The aim of this paper is the scientific analysis of the character image of the fire, and the verification of each fire protection system whether it works well after process of setting up a fire protection system in the utilities tunnel at a constant temperature. The fire experiment was equipped with the linear heat detector, the linear heat detector, the fire door, the connection water spray system and the ventilation system in the utilities tunnel. Fixed portion of an electric power supply cable was coated with a fire retardant coating, and a heating tube was covered with a fireproof. The result showed that the highest temperature was 932℃ and the liner heat detector was working at the constant temperature, and it pointed at the place of the fire on the receiving board, and Fixed portion of the electric power supply cable coated with the fire retardant coating did not work as the fireproof. The heating tube was covered with the fireproof had the function of the fireproof about 30 minutes.

기관지성 방선균증은 매우 예외적이고 드물며 임상양상이 다양하여 폐암과의 감별이 어렵기도 하지만 기관지내시경 검사를 통해 진단할 수 있고 항생제 투여로 완치될 수 있는 질환이다. 저자들은 기관지석과 함께 발현한 기관지성 방선균증을 장기간의 경구 항생제 요법으로 완치한 1례를 경험하였기에 보고하는 바이다. Endobronchial actmomycosis is considered as an exceptional event. We report a case of a 49-year-old woman who presented with cough and exertional dyspnea for 20 months. Her chest X-ray showed calcified lymph nodes in the right lower paratracheal and subcarinal area and consolidation in the right middle lobe. Bronchoscopic examination demonstrated whitish broncholithiasis with mucosal nodularity in the bronchus intermedius obstructing the lumen near-completely. The biopsy specimen revealed sulfur granules and calcified material which were consistent with actmomycosis. Prolonged oral antibiotic treatment resulted in complete recovery, without need for surgical resection.

The purposes of this study were to measure incidence, frequency, type, situation and mechanism, and severity of acute injuries, and to compare the incidence of injury among male and female athletes, in Taekwondo. A prospective design was adopted Data were collected at the 1999 World Taekwondo Championships (l4th) by an injury case form, that contained demographic data, injury situation/mechanism including technique that caused injury, site, type, pre-injury history, severity, and treatment. A total of 563 athletes from 66 countries participated No difference was found between genders in total injury (p > 0.05). Only in the lower Body region was a significant difference between genders found (p = 0.012). Contusions were the most frequent injuries, and the foot was the most frequently injured body part. Injuries were most often the result of delivering a roundhouse kick. The fin-weight division recorded the highest frequency of concussion. In conclusion, there are significant risks of injury in Taekwondo which may be affected by the strategies and techniques adopted during competition, as well as by the equipment and rules of the sport.

Treatment of Refractory <i>Mycobacterium avium</i> Complex Lung Disease with a Moxifloxacin-Containing Regimen

Koh, Won-Jung,Hong, Goohyeon,Kim, Su-Young,Jeong, Byeong-Ho,Park, Hye Yun,Jeon, Kyeongman,Kwon, O Jung,Lee, Seung-Heon,Kim, Chang Ki,Shin, Sung Jae American Society for Microbiology 2013 Antimicrobial agents and chemotherapy Vol.57 No.5

<P>Moxifloxacin (MXF) has <I>in vitro</I> and <I>in vivo</I> activity against <I>Mycobacterium avium</I> complex (MAC) in experimental models. However, no data are available concerning its treatment effect in patients with MAC lung disease. The aim of this study was to evaluate the clinical efficacy of an MXF-containing regimen for the treatment of refractory MAC lung disease. Patients with MAC lung disease who were diagnosed between January 2002 and December 2011 were identified from our hospital database. We identified 41 patients who received MXF for ≥4 weeks for the treatment of refractory MAC lung disease. A total of 41 patients were treated with an MXF-containing regimen because of a persistent positive culture after at least 6 months of clarithromycin-based standardized antibiotic therapy. The median duration of antibiotic therapy before MXF administration was 410 days (interquartile range [IQR], 324 to 683 days). All patients had culture-positive sputum when MXF treatment was initiated. The median duration of MXF administration was 332 days (IQR, 146 to 547 days). The overall treatment success rate was 29% (12/41), and the median time to sputum conversion was 91 days (IQR, 45 to 190 days). A positive sputum acid-fast-bacillus smear at the start of treatment with MXF-containing regimens was an independent predictor of an unfavorable microbiological response. Our results indicate that MXF may improve treatment outcomes in about one-third of patients with persistently culture-positive MAC lung disease who fail to respond to clarithromycin-based standardized antibiotic treatment. Prospective studies are required to assess the clinical efficacy of MXF treatment for refractory MAC lung disease.</P>

정무오,고재웅.Mu O Jung. MD. Jae Woong Koh. MD. PhD 대한안과학회 2012 대한안과학회지 Vol.53 No.12

Purpose: To introduce a more efficient and time-saving scleral fixation technique for a posterior chamber foldable intraocular lens and to report the clinical results. Methods: A foldable acrylic 3-Piece IOL was sutured to the sclera via a small corneal incision. The guiding hollow needle was not used, which differs from other ab externo techniques. Instead, the curved long needle was directly pulled out through the cornea. The scleral flap was not used to bury the scleral suture knot; Instead, the scleral suture knot was translocated at the temporal area. Results: A total of 30 cases were studied retrospectively. The mean follow-up period was 2 years. The IOL was correctly positioned in all cases. There were no major complications, such as endophthalmitis or suture erosion through the conjunctiva. Conclusions: Based on the authors’ experience, the modified ab externo and one-knot technique is a faster and easier technique than the conventional ab externo technique.
