This study aims to explore English teacher-learners’ beliefs about proficiency goals for Korean secondary English education and their intended teaching methods to accomplish the goals. In a qualitative format, with a questionnaire and a question guide, 20 students in a graduate school of education were intervirewed. The interviews were recorded, transcribed, and analyzed for underlying patterns. Finalized patterns underlying the teacher-learners’ goal beliefs and teaching methods are (1) prevalent study perspectives, not use perspectives in identifying the proficiency goals; (2) prioritizing explicit grammar knowledge in proficiency building; (3) preference for a teaching-centered English class regardless of teaching methods; and (4) teacher qualities identified more with text/grammar analysis skills than with English skills. Pro usage and pro teaching are identified as overarching themes in contrast to the prevalent pro use and pro communication of the communicative language teaching principles. The teacher-learners’ lack of consideration of students’ actual English practice/use is noted as well. Based on the findings, the study suggests secondary English curriculum restructuring with consideration of the future teacher candidates’ negative reaction to the current pro-communication policies. Reinforcing English language training for teacher-learners in teacher education programs is also suggested.

This study analyzed characteristics of natural and human environments in Gyeongju's Seochun and Namchun Liver, and suggested nature-friendly planning strategies for self-purification of water quality, biodiversity improvement and conservative waterfront recreation. The environmental analysis included streambed structures, floodplain soils, water quality, vegetation, wildlife, and human facilities. Nature-friendly planning strategies were established based on analysis of the environmental characteristics. They focused on not merely spatial zoning and layout divided into four zones-preservation, partial preservation, conservation, and use, but close-to-nature channel revetment techniques, natural water-purification facilities, biotope diversification, and water-friendly recreation and circulation. Strategies pursued both renewal of stream naturalness and hydraulic stability of streamflow by minimizing transformation of natural channel micro-topography and biotope, and by reflecting natural traces of streambed structures such as revetment scour and sedimentation.

Current web has evolved to a mashed-up format according to the change of the implementation and usage patterns. Web services and user experiences have improved, however, security threats are also increased as the web contents that are not yet verified combine together. To mitigate the threats incurred as an adverse effect of the web development, we need to check security on the combined web contents. In this paper, we propose a scheduling method to detect malicious web pages not only inside but also outside through extended links for secure operation of a web site. The scheduling method considers several aspects of each page including connection popularity, suspiciousness, and check elapse time to make a decision on the order for security check on numerous web pages connected with links. We verified the effectiveness of the security check complying with the scheduling method that uses the priority given to each page. 최근의 웹은 구현 방법과 이용 패턴이 변화되면서 서로 연결되고 융합되는 형태로 변화하였다. 서비스가 진화되고 사용자 경험이 향상되었으나 다양한 출처의 검증되지 않은 웹자원들이 서로 결합되어 보안 위협이 가중되었다. 이에 웹 확장의 역기능을 억제하고 안전한 웹서비스를 제공하기 위해 확장된 대상에 대한 안전성 진단이 필요하다. 본 논문에서는 웹사이트의 안전한 운영을 위해 안전진단을 외부 링크까지 확장하여, 진단 대상을 선별하고 지속적으로 진단하여 악성페이지를 탐지하고 웹사이트의 안전성을 확보하기 위한 스케줄링 방안을 제안한다. 진단 대상의 접속 인기도, 악성사이트 의심도, 검사 노후도 등의 특징을 추출하고 이를 통해 진단 순서를 도출하여 순서에 따라 웹페이지를 수집하여 진단한다. 실험을 통해 순차적으로 반복 진단하는 것보다 순위에 따라 진단 주기를 조정하는 것이 중요도에 따라 악성페이지 탐지에 효과적임을 확인하였다.
A Case of Pulmonary Thromboembolism Complicating Acute Overdose of Benzodiazepines
최재영,정진우 대한응급의학회 2014 大韓應急醫學會誌 Vol.25 No.2
Acute pulmonary thromboembolism (PTE) is a major medicalproblem in many hospitalized patients with medical andsurgical conditions, and venous thromboembolism isresponsible for up to 15% of all in-hospital deaths. However, PTE complicating acute intoxication has beenreported only rarely, and prophylaxis for venous thromboembolismis not routinely incorporated into the managementof acute poisoning in emergency departments or generalwards. We describe here a case of pulmonary thromboembolismthat developed within 48 h of acute benzodiazepineoverdose. A 47-year-old female patient was brought to the emergencydepartment by ambulance. She had been found unconscious,and empty packages of medications prescribed byher psychiatrist and an empty bottle of liquor were found. The estimated drugs and amounts were alprazolam 22.5mg, diazepam 150 mg, flunitrazepam 7.5 mg, fluoxetine150 mg, and propranolol 600 mg. Approximately 40 hoursafter initial presentation, she complained of dyspnea andpulse oxymetry indicated 84%. Her arterial pH was 7.41,pCO2 41.6 mmHg, pO2 46.8 mmHg, and oxyhemoglobinsaturation was 83.4%. The serum D-dimer concentrationwas 2.78 mcg/dL, and computed tomography of the chestshowed acute PTE in the right upper lobar and segmentalpulmonary arteries and both lower segmental pulmonaryarteries. When caring for patients with sedative drug overdose, a highlevel of suspicion of PTE is required, and appropriate diagnosticand therapeutic measures might be undertaken whenPTE is suspected. In addition, appropriate prophylaxis forvenous thrombosis should be considered.
