Membrane structure systems and cable net structure systems are attracting people's attention as they are used in many buildings because of their light materials and airy appearances. If a membrane structure system or a cable net structure system does not have sufficiently high initial stiffness, it may be in unstable state. But if the initial stiffness is secured, the system will be in stable state. In this study the nonlinear finite element formulae for membrane and cable members considering geometric nonlinearity is derived, and then a catenary's membrane structure, and a tension membrane structure by Nass(Nonlinear Analysis for Spatial Structures) program is analyzed. The suitable scheme, which membrane structure are assigned by cable elements for overcoming the unfitted shape problem, is shown that the section of cable is assigned by element's area.

연구목적 : 우리나라에서 산업 재해로 신체적 손상을 입고 입원해 있는 일부 근로자들을 대상으로 PTSD 발병여부를 조사하고, 산업 재해와 관련된 위험 인자를 파악하여 산업재해 이후 근로자들이 겪게 될 신체적 건강문제 뿐만 아니라 정신적 건장 문제 회복에 도움을 주고자 하였다. 방 법 : 2000년 7월에서 2000년 9월 사이에 산업 재해로 인해 신체적인 부상을 입고 입원 중인 인천 소재 산재병원의 남성 입원환자 47명을 대상으로 PTSD 발병여부와 관련 인자를 연구하기 위하여 구조화된 설문 조사와 CAPS를 이용한 진단적 면담을 시행하였다. 결 과 : CAPS를 이용한 면접조사 결과 최종 연구 대상자 47명중 12명(25.5%)이 PTSD로 나타났으며, 모두 증상의 지속 기간이 3개월 이상인 만성 외상후 스트레스장애로 분류되었다. PTSD군 12명과 non-PTSD군 45명을 비교한 결과 BDI, STAI-I, STAI-II, IES 점수는 PTSD 군에서 유의하게 높게 나타났다. 또한 SCR-90-R의 세부항목 중 편집 사고를 나타내는 PAR 점수가 유일하게 두 군 사이에 유의한 차이를 보이지 않았고 그 외의 항목들은 PTSD 군에서 유의하게 높았다. 산재 관련 위험 인자의 비교에서 환자가 주관적으로 보고한 의식의 상실 경험만이 PTSD군에서 유의하게 높게 나타나 이전의 다른 연구자와 일치된 소견을 보였다. 결 론 : 이상의 결과는 산재 사고 이후에 PTSD가 발생하고, 증상이 장기간 지속되어 만성화를 겪을 가능성이 있다는 것을 보여준다. 위험 인자 중에서 사고 관련 위험 인자로 의식의 상실에 대한 주관적인 보고만이 관련성이 있는 것으로 나타났으나, 그 외의 다른 인자들은 관련서이 없는 것으로 나타났다. 그러나 여러 가지 연구의 제한점이 많으므로 연구 시점을 달리하고 많은 대상자를 포함한 후속 연구를 시행해야 산업재해와 PTSD에 대한 이해를 높일 수 있을 것으로 사료된다. Objectives : This study was conducted to assess the development of posttraumatic stress disorder(PTSD) after occupational physical injuries and the risk factors in occupational accident patients for PTSD. Methods : Forty-seven occupational accident patients with physical injuries were administered BDI. STAI I and II, SCL-90-R, IES and questionnaires for risk factors and Clinician-Administered PTSD Scale(CAPS). Results : 1) 12 patients(25%) were diagnosed as PTSD. 2) The BDI, STAI I and II and IES scores are significantly high(<0.05) in PTSD group than non-PTSD group. 3) The subscales of SCL-90-R, with an exception of PAR subscale, showed higher scores(<0.05) in PTSD group. 4) The loss of consciousness(LOC) was only significant risk factor in the occupational accident related factors(<0.05). Conclusion : The results of this study show the development of PTSD among occupational accident patients. The loss of consciousness(LOC) was the only significant risk factor for PTSD in occupational accident patients.

Traditional surgical approaches to orbital medial wall fractures are either extraocular skin incision or indirect bicoronal flap. However these methods can leave remarkable orbital scar or scalp alopecia with possible complications. Endoscopic intranasal visualization of the medial orbital wall and lamina papyracea is a technique familar to otolaryngologists. This endoscopic view allows confirmation of fracture of medial orbital wall and herniation of orbital contents. Good visualization of the fracture can facilitate the anatomic reduction of orbital contents and the proper placement of orbital implant. Two cases of medial orbital wall fracture repaired by intranasal endoscopy using silastic sheet are reported.

Background and Objectives: Rhinosinusitis is the most common cause of olfactory impairment and endoscopic sinus surgery is considered as a surgical procedure of choice for treating chronic sinusitis. CC-SIT (Cross-Cultural Smell Identification Test) consists of 12 items well known in most non-English-speaking cultures. Authors evaluated the therapeutic effects of endoscopic sinus surgery on olfactory dysfuction using CC-SIT. Materials and Methods: The subjects of this study were seventeen sinusitis patient who had undergone ESS from November 2001 through April 2002. All patients were divided into two groups according to nasal polyp and CT findings. CC-SIT was used for the evaluation of olfactory function. Results: Forty seven percents of patients had improvement in olfactory function postoperatively. No correlation was found between changes in CC-SIT score and nasal polyp and preoperative CT findings. Conclusion: It is concluded that nasal polyp and CT findings have no effect on olfaction.

Background and Objectives: Sniffin' Sticks test is the test of nasal chemosensory performance based on pen-like odor dispensing devices. KVSS(Korean Version of Sniffin' Sticks) Test was developed as the "Korean olfactory test" using the odorants which are familiar to Korean. Authors evaluated the clinical validity of KVSS Test compared with CC-SIT (Cross-Cultural Smell Identification Test) in Korean. Materials and Methods: The subjects of this study were 25 normosmic volunteers who were divided into five groups according to age. Each group was 5 normosmic volunteers. And they consisted of 12 men and 13 women. KVSS Test and CC-SIT were used for the evaluation of olfactory function. Results: Our study showed the negative correlation between age and olfactory function test (CC-SIT score, KVSS Test I score and KVSS Test II score). Normosmia rate of KVSS Test was more higher than that of CC-SIT. Also KVSS Test had more familiar items for Koreans compared with that of CC-SIT. CC-SIT score and KVSS Test score showed showed the positive corrclation. And each test revealed high reliability in test-retest evaluation. Conclusion: The KVSS Test can be used as an olfactory function test for Koreans.

교육대학원에 있어서 초등 과학교육 영역의 중요성과 그 운영방안

The future society is expected to be rapidly change in all areas, that is, the length of change time is becoming much smaller than that of generation time. It is very important to prepare the citizens who possess scientific literacy which actively cope with the rapid changes and specialization of society. The sources of rapid changes may be due to the developments in science and technology. Therefore, the importance of science education will be increasingly high. Scientific literacy should be improved basically and systematically from the early stages of formal education. Teachers who are responsible to educate children should be able to research in the areas of science education as well as science itself, and to have capacity to transmit them to the classroom. To do this, the graduate course and the science education within the system beyond the level of college education are essential parts of teacher education. In the graduate course, it is important that science itself and pedagogy of science should be balanced.

Expression and Functional Roles of the Pepper Pathogen-Induced bZIP Transcription Factor CabZIP2 in Enhanced Disease Resistance to Bacterial Pathogen Infection.

Lim, Chae Woo,Baek, Woonhee,Lim, Sohee,Han, Sang-Wook,Lee, Sung Chul APS Press 2015 Molecular plant-microbe interactions Vol.28 No.7

<P>A pepper bZIP transcription factor gene, CabZIP2, was isolated from pepper leaves infected with a virulent strain of Xanthomonas campestris pv. vesicatoria. Transient expression analysis of the CabZIP2-GFP fusion protein in Nicotiana benthamiana revealed that the CabZIP2 protein is localized in the cytoplasm as well as the nucleus. The acidic domain in the N-terminal region of CabZIP2 that is fused to the GAL4 DNA-binding domain is required to activate the transcription of reporter genes in yeast. Transcription of CabZIP2 is induced in pepper plants inoculated with virulent or avirulent strains of X. campestris pv. vesicatoria. The CabZIP2 gene is also induced by defense-related hormones such as salicylic acid, methyl jasmonate, and ethylene. To elucidate the in vivo function of the CabZIP2 gene in plant defense, virus-induced gene silencing in pepper and overexpression in Arabidopsis were used. CabZIP2-silenced pepper plants were susceptible to infection by the virulent strain of X. campestris pv. vesicatoria, which was accompanied by reduced expression of defense-related genes such as CaBPR1 and CaAMP1. CabZIP2 overexpression in transgenic Arabidopsis plants conferred enhanced resistance to Pseudomonas syringae pv. tomato DC3000. Together, these results suggest that CabZIP2 is involved in bacterial disease resistance.</P>
