Primary squamous cell carcinoma of the thyroid gland is an extremely rare case to observe and represents less than 1% in all the primary thyroid malignancies. Normally, squamous epithelium is absent in the thyroid gland and presently; its origin is believed to arise from metaplasia of follicular epithelium. Cancer has very aggressive clinical behavior and a very poor prognosis with survival rates of less than 1 year. The best chances of survival have been achieved with complete resection followed by postoperative radiotherapy. Recently, we came across a case of 80-year-old woman with primary squamous cell cacinoma of the thyroid gland present in the background of Hashimoto's thyroiditis. The patient had swelling in the anterior neck portion from the past 20 days. On physical examinaton, 3×3cm2 hard and fixed ill defined mass was detected in the right lobe of thyroid. Repeated fine needle aspiration biopsy of the thyroid revealed the presence of carcinoma. Apparently, Palliative thyroidectomy was performed after 3 months of diagnosis. During operation, the tumor was revealed as a mass of 100mm in diameter and infiltrated the surrounding muscles, trachea and other soft tissue in the neck. After the operation, the patient's condition deteriorated and ultimately after 5 months of her initial visit, she died due to respiratory failure 저자들은 최근 갑상샘 질환의 기왕력이 없는 고령의 환자에서 전경부 종물을 주소로 내원하여 세침세포흡인 검사에서 정확히 조직형을 진단하지 못한 상태로 보존적 치료로 경과 관찰 중 급속히 진행하여 주위 조직 침범 및 기도 폐쇄를 일으키고 약 6개월 생존 후 사망한 갑상샘의 원발성 편평세포암종 환자를 1예 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Purpose: This study is to compare the knowledge, attitude, and motive for blood donation by university student’s experiences of blood donation. Methods: University undergraduates who attend university located in B-city were interviewed with structured questionnaire about knowledge, attitude, and motive for blood donation from July 4th to 17th in 2016. The number of data was collected from 180 simples. The collected data were analyzed using descriptive statistics, t-test, ANOVA, and correlation analysis using the SPSS WIN 20.0 statistical program. Results: The results of verifying the difference of knowledge and attitude according to the general characteristics of the study subjects are as follows. Blood donation knowledge was significantly difference in grade (F = 3.06, p = .030). Blood donation attitude was significantly difference in major and grade. Blood donation experience was 61.1%. The subjects of the study showed significant correlated with blood donation knowledge and blood donation attitude (r = .872, p <.001). Conclusion: This study was to provide effective way to encourage blood donation looking for improvement by identifying the relationship between knowledge, attitude and motive for blood donation with or without participation.

An intussusception in adulthood is an unusual cause of bowel obstruction. It accounts for up to 5% of all intussusception. Approximately 90% of cases are secondary to a definite lesion such as malignancy or lipoma. Most patients are asymptomatic and the lesion is often detected incidentally at colonoscopy, operation and autopsy. Strangulated intussuscetion is a rare case and also requires emergency operation. A 32-year-old woman visited our emergency room because of severe epigastric pain. Abdominal CT revealed a low density mass in bowel loop and distended small bowel loops filled with fluid. Colonoscopic finding showed huge purple-colored coil-spring lesion in the ascending colon. From this findings, we diagnosed a strangulated intussusception. Surgically removed specimen revealed a small intestinal lipoma. 장중첩증은 대부분 소아에서 흔히 관찰되며 성인에서는 전체 장중첩증의 5%만을 차지한다. 그러나 성인에서 발생할 경우 90%에서는 지방종이나 악성종양 등 2차적 원인에 의한 경우가 많다. 대부분의 환자들은 증상이 없으며 대장내시경검사에서 우연히 발견되는 수가 많아 실제 장중첩증이 관찰되는 예는 매우 드물다. 본원에서는 극심한 복통과 혈변을 주소로 응급실로 내원한 32세 여자 환자에서 시행한 복부전산화단층촬영에서 하복부의 소장고리 내부에 저밀도의 종괴가 겹으로 둘러싸인 소견과 대장내시경 검사에서 상행결장에서 맹장에 이르기까지 결장 내부를 거의 막고 있는 거대한 다엽성 자줏빛의 종괴를 관찰하고 감돈된 장중첩증으로 진단한 후 응급수술을 시행하여 소장지방종으로 진단된 1예를 경험하였기에 보고하는 바이다.

Objectives : Research on the effect and satisfaction between Acupuncture Treatment, Physical Treatment and contemporary Treatments of Acupuncture and Physical of lumbago patients Methods : We separated lumbago patients into three groups. A group with only Acupuncture Treatment and a group with only Physical Treatment and a group with contemporary treatments of Acupuncture and Physical. Questionnaire survey and score of Visual Analog Scale(VAS) and Oswestry Disability Index(ODI) were examined for comparison. Results & Conclusion : 1. Of the 54 patients Acupuncture Teatment group had 17 patients with similar ratio of gender and the average age was 39.5 years old. For the Physical Treatment group the ratio of male was 75% of the 8 patients and had the youngest average age which was 29.1 years old and the group with contemporary Treatments the ratio of female was 62% of 29 patients and had the oldest average age which was 46.7 years old. 2. The Acupuncture Treatment group had the shortest treatment period because of many acute stage caused by lumber sprain and the improvement score was the best. The group of contemporary treatments had the longest history day and treatment period by serious disease like HIVD and spinal stenosis but the improvement score of VAS and ODI was good similar to the Acupuncture Treatment group. For the Physical Treatment group there was many patients with degenerative change but not severe pain. The VAS, ODI and the improvement score was the lowest before and after the treatment.
전극 내 고분자 바인더 함량에 따른 접착력 및 전기화학 성능 평가

전기자동차의 경우, 내연기관 자동차와 동일 수준의 일 충전 주행거리를 확보하기 위해 전지의 고에너지밀도가 요구되고 있다. 해당 조건을 만족시키기 위해 전극 내 활물질의 함량을 높여 에너지밀도를 높이는 연구가 진행되고 있으나, 동일 로딩레벨 및 밀도에서 전극의 기계적 특성 및 전지의 장기 신뢰성이 상이할 수 있다. 이러한 기계적 특성이 확보되지 않은 전극은 전지 수명에 치명적이며, 이를 해결하기 위해 전극 내 기계적 특성 및 전기화학 성능의 최적화가 필수 선행되어야 한다. 본 연구에서는 전극 내 고분자 바인더의 함량을 1, 2, 4 wt%으로 조절하고 동일한 로딩레벨, 밀도를 갖는 복합전극을 제조하였다. 전극의 기계적 특성을 SAICAS를 통해 분석한 결과, 바인더 함량이 2wt%인 전극은 4wt% 전극에 비해 절반정도의 접착력을 보였으며, 실제 수명 평가 이후 해당 전극이 집전체에서 대부분 박리되는 것을 확인할 수 있었다. 본 연구를 통해 기계적특성과 전지 수명간의 상관관계를 확인하였으며, 이를 보고하여 전극 내 접착 특성이 면밀히 분석되어야 함을 제안한다.
