Purpose: Multiple endocrine neoplasia type I is rarely reported in Korea. The purpose of this study is to analyze the clinical features and the treatment of MEN1 which had been carried out in our institution. Methods: Eight patients underwent surgery for MEN1-related hyperparathyroidism, duodenopancreatic tumors and pituitary tumors at our institution and were reviewed retrospectively. Results: Of the eight patients, all patients had hyperparathyroidism. There were 5 total parathyroidectomy patients and 3 subtotal parathyroidectomy patients, none of them had persistent and recurrent hyperparathyroidism after operation. However, one of total parathyroidectomy patients had persistent hypoparathyroidism. Of the 8 patients, seven had duodenopancreatic tumors; four of them had pancreatic islet-cell tumors, two had malignant gastrinoma and one had Zollinger- Ellision syndrome. Pituitary tumors were observed in 6 patients among the 8; four of them had prolactinoma, and 2 had adenoma which was confirmed by magnetic resonance imaging. Of the eight patient, only one patient was confirmed to have another MEN1 family member and the mutation of MEN1 gene on chromosome 11q13 was proved on gene study.Conclusion: The clinical features of these patients were similar to those in other reports and the results of surgical treatment were relatively satisfactory. However, the detection of other MEN1 patients among the family members was relatively poor. Close follow up of family members and gene study will be required. (Korean J Endocrine Surg 2004;4: 31-35)

김연선,홍석준,Yon-Seon Kim,M.D. and Suck-Joon Hong,M.D. 대한갑상선-내분비외과학회 2004 The Koreran journal of Endocrine Surgery Vol.4 No.2

Purpose: The extent of prophylactic lateral neck lymph node dissection is very controversial in medullary thyroid cancer. This retrospective study was undertaken to evaluate the efficacy of prophylactic lateral neck lymph node dissection. Methods: A total of 29 patients underwent curative operation for medullary thyroid carcinoma at our institution. Of these 29 patients, 13 patients had prophylactic lateral neck dissection and 16 patients had non-prophylactic lateral neck dissection. Among 13 patients, one-compartment prophylactic lymph node dissection was performed in 10 patients and two-compartment prophylactic lymph node dissection was performed in 3 patients. Postoperative calcitonin level was evaluated between these groups. Results: A normalized calcitonin level was detected after surgery in 74% of patients without lateral neck lymph node metastases, and in 10% of patients with lateral neck lymph node metastases. In comparison of prophylactic node dissection group and non-prophylactic node dissection group, the rate of normalized calcitonin level after surgery is 100%, 66.7% in stage 1, 100%, 50% in stage 2, 0%, 80% in stage 3, 14.3%, 0% in stage 4. In the patients who one-compartment prophylactic lymph node dissection was performed, 40% of patients had positive lymph node metastasis, and 70% had persistent hypercalcitoninemia. However, there was no postoperative hypercalcitoninemia in the patients with two- compartment prophylactic lymph node dissection although lymph node metastasis was not identified with pathologic examination. Conclusion: Prophylactic lymph node dissection was more effective in the early stage of medullary thyroid carcinoma than late stage. The two or more compartment lymph node dissection is more effective than just one-compartment dissection for the normalization of serum calcitonin level. (Korean J Endocrine Surg 2004;4:85-89)

펄스 복사 능력 개선을 위한 리플형 광대역특성을 갖는 비선형 와이어안테나 설계에 관한 연구

김연선,박의준,Kim, Yeon-Seon,Park, Ui-Jun 대한전자공학회 2002 電子工學會論文誌-TC (Telecommunications) Vol.39 No.3

펄스 안테나로 많이 사용되는 종래의 직선형 혹은 V-형 안테나의 원거리전장은 null점들을 갖는 주파수 특성을 가지므로 제한된 펄스 복사 능력을 가진다. 이를 개선시키기 위해 비선형적 형상을 갖는 와이어안테나의 합성법을 제안하였다 즉, 복사 전장의 주파수 의존성을 최소화시키는 형상방정식을 유도하고 그 해를 산출하므로서 리플형의 광대역 특성을 갖는 형상을 합성하였다. 그 결과 매우 넓은 주요 스펙트럼을 갖는 짧은 펄스의 복사에 유리함을 보였다. 따라서, 펄스폭이 좁을수록 합성된 다이폴 안테나 특성이 종래의 선형 다이폴 보다 우수한 피크치를 갖는 펄스 복사가 이루어짐을 보였다. 전류 분포 및 원거리 전장의 과도해석을 위해 모멘트법에 기반한 역 이산 푸리에 변환을 사용하였다. A nonlinear shaping method for a wire antenna is presented to improve the limited pulse radiation ability due to the frequency characteristics with nulls which are found in the conventional straight or V antennas. The developed scheme is based on the minimization of frequency-dependence of the radiated electric field intensity over wide band, hence giving the ripple-type frequency characteristics. It is shown that the synthesized shape has more advantage in the case of shorter pulse. That is, we found that for shorter pulse exciting, the radiated peak value of the synthesized antenna is larger than that of the conventional linear antenna. The inverse discrete Fourier transform based on the moment method is used for the transient analysis of current distribution and far field electric field.

목적 : 적절한 혈액투석의 평가에 요소역동학을 이용한 Kt/V지표가 사용되나 일부 환자에서는 적절한 Kt/V값을 유지하지 못하여 이로 인한 임상적 문제가 발생할 수 있다. 저자들은 통상적인 주 3회, 회당 4시간의 혈액투석을 처방받는 환자에서 처방된 투석량과 전달된 투석량을 조사하고, 부적절한 투석량 전달에 미치는 요인을 분석하고자 하였다. 방법 : 안정된 상태로 투석 중인 97명의 만성신부전 환자를 대상으로 처방된 투석량은 Kt/V공식에서 K값으로 in vitro 요소청소율을 V값으로 Watson 식을 이용한 요소분포용적을 구하여 계산하였고, 전달된 투석량은 Daugirdas의 single pool, variable volume공식을 사용하여 계산하였다. 또, 전달된 투석량에 영향을 줄 수 있는 기술적, 임상적 인자들별로 전달된 투석량의 차이를 분석하였다. 결과 : 처방된 투석량의 평균은 1.37±0.21, 전달된 투석량의 평균은 1.23±0.27로 양의 상관관계는 있었으나 유의한 차이를 보였다(p<0.03). 전달된 투석량이 1.2 미만인 군은 45%였고, 이 군은 체중이 높았으며, 투석 처방량이 낮았다. ΔKt/V값은 헤파린을 사용한 군에서 사용하지 않은 군에 비해 유의하게 낮았으며(0.11±0.16 vs. 0.28±0.20, p<0.002), 저혈압, 투석 중 증상, 투석시간의 단축, 재순환율 등의 인자에 따른 차이는 보이지 않았다. 결론 : 통상적인 투석 처방으로 혈액투석 중인 환자에서 체중, 투석 처방량, 헤파린 사용 여부 등의 인자들이 투석의 적절도에 영향을 줄 수 있으므로 환자에 따른 개별적 처방이 필요함을 알 수 있었다. Background : Although adequate removal of small solutes are essential for effective hemodialysis, many patients are suffering from inadequate delivery of hemodialysis, especially with the conventional fixed regimen of dialysis for 4 hours three times per week. We tried to evaluate actual delivered dose of hemodialysis in patients receiving 4 hours of low-flux hemodialysis, and to analyze factors affecting inadequate delivery of hemodialysis. Methods : 97 stable maintenance hemodialysis patients who were undergoing 4 hours of hemodialysis thrice weekly were included for analysis. Prescribed dose of dialysis was calculated by Kt/V where K was in vitro urea clearance of dialyzer membrane and V was estimated according to the Watson`s formula. Delivered dose of dialysis was calculated according to the Daugirdas equation. To find factors that may impair adequate delivery of hemodialysis, various clinical and technical parameters were analyzed. Results : Prescribed dose of hemodialysis was 1.37±0.21, while delivered dose was 1.23±0.27, and thus, there was a significant difference (p<0.03). In 45% of the patients, delivered dose was less than 1.2. They were heavier and prescribed dose was low. ΔKt/V (Prescribed dose-Delivered dose) was significantly greater in patients who did not use heparin therapy compared to patients who used heparin. Other parameters such as hypotension, missed treatment, sex, type of vascular access and degree of recirculation were not associated with impaired delivery of hemodialysis. Conclusions : Delivered dose of hemodialysis can be affected by patient`s body weight, prescribed dose and heparin use in conventional low-flux hemodilaysis regimen. Therefore, each patient should be prescribed individually for adequate delivery of hemodialysis, and delivered dose should be measured regularly.(Korean J Med 69:510-517, 2005)

Objectives: 현재 장애인의 구강건강은 구강건강전문인력인 치과위생사가 아닌 사회복지사가 책임지고 있는 실정이다. 장애인 복지시설에 상주하는 사회복지사에게 올바른 구강건강 관리방법을 제공함으로써 장애인 구강건강의 형평성 제고를 도모하고자 한다. Methods: 2019년 4월 13일부터 2019년 4월 20까지 서울시 송파구에 위치한 'o' 장애인 복지시설에 거주하는 1급 지적장애인을 대상으로 식후 치과위생사 4명과 사회복지사 4명이 잇솔질 시행 후 구강환경관리능력지수(PHP Index)를 측정하여 비교하였다. 사전에 사회복지사 4명에게 잇솔질(회전법)을 교육하였으며, 잇솔질 방법과 검사 측정 도구를 통일하였다. 대상자의 구강보건지식을 평가하기 위해 자기기입식 설문지를 사용하였고, 구강보건지식점수 및 구강환경관리능력지수(PHP index) 점수의 평균, 대상자의 일반적 특성에 대해 Microsoft Office Excel ver.2016 을 이용하여 빈도 및 백분율 산출하였다(N%). Results: 치과위생사와 사회복지사의 구강보건지식 조사에서 모든 문항에서 치과위생사가 높은 점수를 나타냈다. 치과위생사와 사회복지사가 지적장애인을 대상으로 잇솔질(회전법) 실시 후 구강환경관리능력지수(PHP Index)를 비교했을 때 연령별, 성별 모든 분류에서 치과위생사의 구강환경관리능력지수(PHP Index)가 낮게 나타났다. 2차에 걸쳐 치과위생사와 사회복지사가 지적장애인을 대상으로 잇솔질(회전법) 실시 후 구강환경관리능력지수(PHP Index)를 비교했을 때 1차, 2차 모두 치과위생사의 구강환경관리능력지수(PHP Index)가 낮게 나타났다. Conclusions: 이상의 결과를 종합해 볼 때, 장애인들의 구강건강관리를 위해 치과위생사가 사회복지사보다 구강건강관리능력이 더 효율적인 것으로 나타났다. 따라서 장애인들의 입소시설에 치과위생사가 구강건강관리전문 인력으로 배치되어 장애인 및 사회복지사의 교육을 담당할 수 있는 환경이 조성되어야하며, 치과위생사를 양성하는 대학의 교육과정에도 장애인의 특성을 이해하는 교과목이 개설되어 전문성이 제고되어야 한다. Objectives: Currently, oral health of the disabled is taken care of by the social workers, not by dental hygienists, who are the oral health professional in this area. Therefore, we aim to enhance the equity of oral health for the disabled by providing the correct oral health care method to social workers residing in the welfare facility for the disabled. Methods: Four dental hygienists and four social workers were given the class I intellectual disabilities living in 'o' welfare facilities for disabled people in Songpa-gu, Seoul from April 13, 2019 to April 20, 2019. Patient Hygiene Performance(PHP) Index were measured and compared. In advance, the social workers were taught brushing (Rolling method), and the method of brushing and measuring tools were integrated. Results: Twice a total of dental hygienists and social workers practiced toothbrushing(Rolling method) for the class I intellectual disabilities who is a person to be brushed. When comparing the Patient Hygiene Performance(PHP) Index after the second round, the result shows that both the first and second dental hygienists' Patient Hygiene Performance(PHP) Index is lower. Conclusions: Comparing oral health knowledge level and Patient Hygiene Performance(PHP) index of dental hygienist and social workers, the result shows that dental hygienist has higher oral health care ability. Therefore, the dental hygienist should be placed in welfare facility for the disabled as an expert in oral health management to create an environment in which the disabled and social workers can be trained. In addition, the curriculum of the college that nurtures the dental hygienists should have a course to understand the characteristics of the disabled person in order to enhance the professionalism of dental hygienists.
