Idiopathic cricopharyngeal achalasia is a rare condition that produces oropharyngeal dysphagia. It is caused by spasm of the cricopharyngeus and inability to relax with swallowing. A prominent muscle bar at the upper esophageal sphincter is a typical finding of the esophagogram. Cricopharyngeal myotomy is the treatment of choice. We report a case of cricopharyngeal myotomy for 61-year-old female patient.

다양한 유무선 단말의 등장과 함께 원하는 곳에서 시간에 제한없이 네트워크에 접속할 수 있는 유비쿼터스 세상이 눈앞으로 다가왔다. 네트워크 접속이 현대인 생활의 일부분이 된 현실에서 과다 트래픽 발생으로 인한 급작스런 네트워크 상의 장애는 유비쿼터스 환경에서 무엇보다도 큰 위협이라 할 수 있다. 따라서 비정상적으로 발생한 과다 트래픽을 빠르게 탐지하여 대응하는 것은 유비쿼터스 환경을 안전하게 보호하기 위한 필수 요소라 할 수 있다. 본 논문에서는 기존의 트래픽 분석과는 달리 흐르는 네트워크 패킷의 5 tuple 정보를 실시간으로 수집하여 과다/이상 트래픽을 즉각적으로 탐지하고, 이를 자동으로 제어하는 메커니즘에 대해서 소개하고 있다. 실시간으로 8초마다 트래픽 정보를 수집하고 이를 분석하여 트래픽의 특성을 구분 및 위협도를 분석하여 이를 바탕으로 트래픽 제어 정책을 생성 및 적용하는 전반적인 과정에 대한 것이다. 여기에는 본 메커니즘을 실제 테스트망에서 시험한 결과도 포함하고 있다.

오존은 대기의 산화력을 증가시켜 화학 반응으로 인한 미세 먼지를 생성시키다. 이로 인하여 시정장애 등의 원인이 되어 대기질을 악화시키는 역할을 한다. 이러한 오존의 고농도 현상이 1994년부터 수도권 지역을 비롯한 전국 대도시 지역에 빈번히 나타나기 시작하여 이에 대한 연구의 필요성이 절실히 요구된다. 고농도 오존의 원인과 이론적 해석을 위해서는 측정과 모사를 병행한 연구가 요구된다.(중략)

여성 IT 전문인력 육성은 사회제도와 조직문화가 여성인력을 수용하도록 개선되고 수요자인 기업이 여성인력을 유치하고 보유하려는 시도가 매우 중요하다. 한국통신학회 정보통신여성위원회에서는 사회제도와 조직문화적 측면에서여성의 IT 산업진출장애에 대한 논의는 여성의 사회진출관련 광범위한 잉슈를 포함하게 됨으로서 본고에서는 IT 여성 전문인력 육성방안모색을 주요내용으로 한다. 따라서 IT 전문 인력범위를 살펴보고 주변인이 아닌 핵심인력으로 육성키 위한 방안으로 장기적 추진방향과 산.학.연.관 협력추진활동을 제언한다.

굳은 손, 힘겨운 발걸음 등 이만재(51) 씨의 첫인상은 여느 장애인과 다르지 않았다. 하지만 그의 눈빛을 보니 생각이 달라질 수밖에 없었다. 또렷하면서도 당당함이 가득한 눈. 일상생활에서는 쉽게 마주칠 수 없는 시선이었다. 혹시나 해서 그의 아내분께 전 직업을 물어 보니 대위로 예편을 한 후 20년간 국방과학연구소에서 근무를 했다고 한다. 그는 군인이었다. 그제야 수긍이 갔다. 눈빛엔 장애라는 허울을 뚫고 애국심과 자긍심이 넘쳐흐르고 있었다. 산재로 인해 안타깝게 국방의 일선에서 벗어난 그를 만나봤다.

Personality characteristics of recurred TMD patients were analyzed psychologically by using the SCL-90-R. 27 recurred TMD patients, 45 new TMD patients, control I were subjected at Orofacial pain clinic, Department Of Oral Medicine and Health Promotion Center, Pusan National University Hospital during the period from 2005 to 2006. 50 general dental patients, control II were subjected at a local dental office in Pusan during the same period. The obtained results were as follows. 1. Mean values of T-scores on 9 basic scales in all the groups were within normal range. 2. The T-scores of IS, Dep, Phob, Psy in general Dental patient group were significantly higher than those in recurred TMD patient group. 3. As compared with recurred TMD patient Group & control I group by sexual subclass, there was no significant difference of the scales. 4. As compared with acute and chronic groups, there was no significant difference of the scales in recurred TMD patient group. However, the T-scores of Som, Par, Phob, Psy in chronic new TMD patient group were significantly higher than those in acute new TMD patient group, control I group.

Recently, the many anti- stigma program use the 'mental illness is an illness like any other biogenetic illness' approach. This is based on Weiner's attribution affection theory. However, mental illness is difficult to be applied with attribution affection premise because attributing no blame for mental problem(biogenetic cause) leads to fear and dangerousness. We proposed a modified attribution affection model that explains the relations between biogenetic causal belief and social distance. Our model assumed that attributing personal responsibility for each mental problem leads to anger and social distance. And attributing no blame for mental problem(biogenetic causal belief) reinforces perception of dangerousness and social distance. This study presented typical vignettes of schizophrenia, depression and alcoholism according to the diagnosis criteria of DSM-IV to 768 university students randomly. Path analysis was used to test modified attribution affection model. The major findings are, First our original model modified partially for fit index. So final model assumed that i) The more respondents believed personal responsibility, the more anger, the more anger reaction corresponded closely with more social distance. ii) biogenetic causal beliefs leads to a worsening of dangerousness and perception of dangerousness leads to a increasing of social distance. Second, multi-group analysis was conducted to verify how a modified attribution affection model would be applicable to three groups. The result is that there is no difference among three groups. Finding from this research suggest to change anti-stigma program that use medical model.

As a number of potential endocrine disrupting compounds (EDCs) are released into the environment, recently growing attention has been drawn to them. Therefore sensitive and reliable analytical methods are essential to monitor those compounds. In this study, complementary CC-MS and LC-MS were employed to analyze the endocrine disrupters, and the results of two methods were compared for di(2-ethylhexyl)phthalate (DEHP), benzylbutylphthalate (BBP), pentachlorophenol (PCP), and 4,4'-Isopropylidenediphenol (Bisphenol-A, or BPA). The results indicate that it was possible to lower the detection limits of EDCs by LC-MS. Also, LC-MS enabled to identify the EDCs as almost intact molecules. Furthermore, this study presented a nanofiltration membrane (MWCO 250) and a ultrafiltration membrane (MWCO 1,000) filtration system as methods far removing EDCs from drinking water containing $\gamma$-BHC, p,p'-DDE, BBP, p,p'-DDT, DEHP, PCP, and BPA. Cross-flow type nanofiltrations showed $100\%$ removal of EDCs, and the result implies that MWCO 250 nanofilter was sufficient for treatment of EDCs. The ratio of permeate flux to mass transfer coefficient of nanofiltration, high flux ultrafiltration, and low flux ultrafiltration with ultrapure water were 0.67, 3.4, and 0.44, respectively. It was found that nanofiltration and low flux ultrafiltration were operated at a diffusion dominant condition, and the high flux ultrafiltration was operated at a convection dominant condition. Furthermore, a diffusion dominant process attained reasonable rejection of EDCs. The removal in the ultrafiltration was depending on the molecular weight of an EDC, and the filtration was governed by diffusion-dominant hydrodynamic conditions.

There is an increasing emphasis on science teaching in inclusion education setting, but still few research and practice in science education field including science teacher training course as well. It is well known that teaching efficacy of teacher is an important factor to influence teaching behavior and students' learning, but it is hard to find related studies about self-efficacy on teaching science for the disabled students. In this study pre-service science teachers' self-efficacy on science teaching for the disabled students was investigated and analyzed. For this a questionnaire consisted of 3 sub-scale like learning efficacy scale, teaching efficacy scale, and outcome expectancy scale was enacted to 97 pre-service science teachers. As a result, pre-service science teachers showed relatively low efficacy in teaching but showed positive learning efficacy and outcome expectancy. There was no meaningful difference in distribution of efficacy belief by gender, however the experience of teaching science for the disabled students made difference in outcome expectancy. From this study the implication for science teacher training course was inferred to meet the needs for science education in inclusion setting.
