N/A Background/Aims: The efficacy of misoprostol was evaluated in patients with esophageal varices bleeding or ascites caused by liver cirrhosis. Methods: The effects of misoprostol on portal hypertensive patients were observed in two groups, a group of 30 patients receiving misoprostol and a control group of 30 patients receiving conventional treatment. We detected ascites with abdominal ultrasonography and compared the misoprostol-diuretics group with the cluretics only group for ascites control. Hemodynamic condition after the administration of misoprostol was observed by measuring changes in volume and velocity of blood flow in portal vein using pulsed Doppler ultrasound. We also made comparisons between the misoprostol only group, EVL-misoprostol group and conservative group for esophageal varices rebleeding episodes during the follow up periods of 6-9 months. Results: In 14 of 18 cases (77.8%), the increase in the velocity and volume was observed and in the remaining 4 cases (22.2%), either a reduction or no change was observed. We observed the effect of misoprostol on ascites in two groups; one group receiving a combined treatment of misoprostol and diuretics, the other group receiving diuretics only. There was a statistically significant effect in the combined treatment group (P<0.05). The recurrence of bleeding after treatment was observed for 6 to 9 months. Rebleeding from esophageal varices occurred in 1 of 12 cases (8.3%) in the misoprostol group and 4 of 13 cases (30.7%) in the non-misoprostol group (P<0.05). However, there was no recurrence of bleeding in 10 patients who were treated with endoscopic variceal ligation and misoprostol during the follow up period. Conclusion: Misoprostol might be a very useful agent in the control of ascites and the prevention of rebleeding of esophageal varices caused by liver cirrhosis.

For malignant neoplasms of salivary tissues. two of the better determinants of progosis are histologic classification and size of the neoplasm. Proper management of these tumors requires an accurate diagnosis by the pathologist and correct interpretation by the surgeon. Malignant mixed tumors account for between 3 and 13 precent of all cancers of the salivary glands and 2 percent of all tumors in these locations. The typical history of these tumors is that of slowly growing mass demonstrating a sudden increase in growth. The duration of onset of the tumor mass and the diagnosis of malignancy has been demonstrated to be 10 to 18 years. The risk of malignat transformation of a benign mixed tumor increases with the duration of the tumor. We analyzed retrospectively 13 cases of malignant mixed tumor who visited from Jan. 1985 to Dec. 1992. Mean age of the patients was 56.5 years. The origin of tumors were parotid gland 7 cases, submandibular gland 2 cases, and minor salivary gland 4 cases(palate 3 cases, tonsil pillar 1 case). According to the criteria of the AJCC on staging, stage I was 1 case, stage II 1 case, stage III 2 cases, and stage IV 9 cases. Histopathologically, carcinma ex pleomorphic adenoma were 12 cases and the true malignant mixed tumor was 1 case. The major treatment modalities were curative surgery, and radiation therapy followed. In conclusion, aggressive therapy of combined surgery and postoperative radiation therapy is required for these lesions, and patients with known or suspected benign tumor should be encouraged to undergo surgery early on in their disease to avoid malignant degeneration at a later dete.

목적 본 연구는 대학 구조 조정이 비정규직 교수, 특히 원어민과 비원어민 영어 교수에게 미치는 영향을 탐구하였다. 방법 이를 위하여 2005년에서 2019년까지 대학교 고용 구도에 영향을 미친 법률과 규정을 분석하였고, 그 결과를 조사하기 위해 교육적 통계자료를 분석하였다. 또한, 분석 결과에 질적인 맥락을 부여하기 위해 원어민 교수 다섯 명과 비원어민 교수 다섯 명을 면담하여 그 결과를 분석하였다. 결과 분석 결과는 다음과 같다. 1) 분석한 법률은 제정될 당시의 의도와는 다르게 대학의 비정규직 교수들에게 부정적인 영향을 미쳤으며, 2) 원어민과 비원어민 교수의 삶은 사회 구조적 제약에 영향을 받았으며, 3) 결과적으로 줄어든 일자리를 얻기 위한 원어민과 비원어민 교수 사이의 경쟁이 심해지고 개개인의 교수들은 학문적 일자리를 유지하기 위해 끝없는 경쟁을 하게 되었다. 결론 이 결과는 비정규직 교수가 마주하는 문제는 개인적 문제가 아니라 사회적 문제이며 따라서 교육행정가, 교육부, 정부는 대학의 교원들이 필요 이상으로 과도한 경쟁에 내몰리는 것을 방지하도록 노력해야 한다는 것을 암시한다. 또한, 연구 결과에서 비정규직 교수는 변화를 끌어내는 힘은 개인에게 있음을 인지해야 한다는 것을 유추할 수 있다. Objectives The study aimed to investigate how the restructuring of higher education in Korea influenced contingent faculty, in particular, NESTs and NNESTs. Methods Laws relevant to academic labor from 2005 to 2019 were collected and analyzed, and the educational statistics were also collected and analyzed to support the results of the analysis of the laws. Furthermore, five NESTS and five NNESTs were interviewed to provide the contexts to the quantitative data. Results The results reveal that 1) despite their original intentions, the laws negatively influenced contingent faculty in higher education, 2) the personal and professional lives of NESTs and NNESTs were affected by social-structural constraints, and 3) as a result, the competition between NESTs and NNESTs for reduced job openings grew, and individuals struggled to secure their position in the academic job market. Conclusions The findings imply that the problems that contingent faculty face are not individual problems but social-structural problems, so educational administrators and the Ministry of Education should work on preventing the academic job market from becoming more competitive than necessary. Contingent faculty also need to be aware that individuals have power to bring about change.

본 연구는 현재 공립학교 체제 속에서 실시되고 있는 공립유치원 교원평가의 실태 및 현행 교원평가에 대한 공립유치원 교사들의 인식, 앞으로 실시될 교원평가에 대한 인식을 조사하여 공립유치원 교원의 교육수행 지원과 교원평가체제 개선을 위한 기초자료를 제공하고자 하였다. 공립유치원 교원들은 현행 교원평가의 실시에 대해 알고 있으나 교원평가의 결과활용에 대해서는 과반수에 가까운 교사들이 알고 있지 않았으며, 그외 교사들은 교원평가를 근무지 이동, 성과급 지급 등과 같은 보상과 관련하여 인식하고 있었다. 직위에 따라 교원평가에 대한 인식의 차이가 있었는데, 원장ㆍ원감은 교원평가에 대한 필요성과 공정성, 기여도를 높게 인식하고 있는 반면, 교사들은 교원평가의 적절성, 만족도, 영향력, 기여도면에서 상대적으로 부정적인 인식을 가지고 있었다. 새로운 교원평가에 대해서 원장ㆍ원감은 동료와의 관계나 학부모와의 관계가 부정적으로 변할 수 있을 것이라고 인식하고 있었다. 교사들은 새로 도입될 교원평가에 대하여 기관단위의 평가, 자기평가, 학년도 말, 격년제 이상의 평가 간격 등을 선호하고 있었는데, 이를 통해 교사들이 교원평가에 대한 심리적 부담이 크다는 것을 알 수 있다. 따라서 현행 및 새로 도입될 교원평가에 대한 충분한 안내를 통한 공감대 형성뿐만 아니라 다양한 집단참여의 교원평가과정에 대한 숙의과정이 더욱 필요하며, 유아교육현장의 특성을 반영한 교원평가를 준비하기 위해 충분한 논의가 필요하다. The purpose of this study was to present basic data for public kindergarten teacher assessment by investigating how to actually conduct the teacher assessment what was teaching staff's perception of the assessment and newly enforced teacher assessment. The research questions for the purpose of the study were as follows: 1. Is there any difference in awareness of the practice of current teacher assessment between public kindergarten principals, assistant principals, and teachers? 2. Is there any difference in awareness about the current teacher assessment between public kindergarten principals, assistant principals, and teachers? 3. Is there any different awareness about the newly enforced teacher assessment between public kindergarten principals, assistant principals, and teachers? The results were as follows; First, for the practice of current teacher assessment, most of public kindergarten teaching staff have conducted work performance evaluations, some of the public kindergarten teaching staff had no idea about the practical use of the assessment and others knew the practical use of the assessment, which was used for relocation, and extra payment. Second, there is a significant difference between principal, assistant principal and teachers's perception about the assessment itself, necessarily. Teachers had more negative views than principals and assistant principals, but agreed the assessment was necessary. Teachers knew about the current teacher assessment in general and had negative opinions about appropriateness, management satisfaction, fairness and contributions of teacher assessments, but these assessment influenced them. Third, for the newly enforced teacher assessment, most principals and assistant principals knew about the new assessment but most teachers did not.

Malignant rhabdoid tumors arise primarily from the kidney. Extrarenal malignant rhabdoid tumors are rare, with the liver, central nervous system, and skin reported as the primary sites. Malignant rhabdoid tumors of the mediastinum are extremely rare among extrarenal malignant rhadoid tumors; only 3 cases have been reported to date, all characterized by aggressive clinical behavior. We experienced a 35-year-old woman diagnosed with malignant rhabdoid tumor in the anterior mediastinum with multiple metastases. The tumor was surgically unresectable, and treated with palliative radiation therapy. Three-month after radiation treatment, she died from dissemination of the malignant rabdoid tumor.

본 논문에서는 밀리미터파(W 대역) 다중개구각 혼안테나를 제안하였다. 제안된 안테나는 전계면 및 자계면 빔폭이 동일한 다중모드 이중편파 정사각형 혼으로서 다중모드 생성부, 4개의 정사각형 도파관 여기부, 합패턴 형성을 위한 직교모드 변환기와 전력결합기로 구성된다. 제작이 용이하도록 안테나 구조를 설계하고, 층별 기계가공과 확산접합 기법을 적용하여 ±0.02 ㎜ 오차 이내로 제작하였다. 회로망분석기와 원전계 측정시설을 이용하여 제작된 안테나의 입력 반사계수와 방사패턴을 측정하였다. 측정 결과, 제안한 안테나는 중심 주파수를 기준으로 1 ㎓ 이내에서 17.7~18.3 ㏈i의 이득, 25.2~28.5°의 빔폭, 1.02~1.75의 입력 VSWR 특성을 가짐을 확인하였다. This paper presents an implementation of a millimeter-wave(W band) multiflare-angle horn antenna. The proposed antenna is a multimode dual-polarized square horn having equal E- and H-plane beamwidths and consists of a multimode generating section, a four-square-waveguide exciter, orthomode transducers, and power combiners for the sum pattern formation. The antenna structure has been designed to allow for easy fabrication and the designed antenna has been fabricated to a precision of ±0.02 ㎜ by layer-by-layer machining and diffusion bonding. The input reflection coefficient and the radiation pattern of the fabricated antenna have been measured using a network analyzer and a far-field test facility. Measurements show that the proposed antenna has 17.7~18.3 ㏈i gain, 25.2~28.5° beamwidth, and an input VSWR between 1.02~1.75, within ±0.5 ㎓ from the center frequency.
