Malignancy Rate in Sonographically Suspicious Thyroid Nodules of Less than a Centimeter in Size Does Not Decrease with Decreasing Size

황보율,안화영,이연희,이예진,김정희,온정헌,홍은실,김경원,정인경,최성희,임수,박도준,장학철,오병희,조보연,박영주 대한의학회 2011 Journal of Korean medical science Vol.26 No.2

We evaluated the malignancy and nondiagnostic rates using fine needle aspiration cytology (FNAC) results in thyroid nodules smaller than 1 cm according to the subdivided size. We retrospectively reviewed the medical records of all subjects underwent FNAC from 2003 to 2009 in our hospital, and 2,756 patients of subcentimeter thyroid nodules with one or more suspicious sonographic features and 7,105 with nodule sized 1 cm or more were included. The malignancy rate was higher in those subcentimeter nodules with suspicious sonographic findings than the nodule sized 1cm or more (19.7% vs 7.8%, P <0.001). We grouped the nodules based on size with mm interval and observed that the malignancy rate did not decrease but the nondiagnostic results increased its size decrement. When we divided the subjects arbitrarily into a 5 mm or smaller and a 6-9 mm sized group, nondiagnostic cytology findings were reported more frequently in the smaller group (24.3% vs 18.1%, P = 0.001), while the rate of “malignant” was similar (18.3% vs 15.5%, P = 0.123) and the rate of “suspicious for malignancy” was higher (6.8% vs 2.9%,P < 0.001). Therefore when we decide to perform FNAC or not in subcentimeter-sized nodules, we should consider sonographic findings and other clinical risk factors but not the nodular size itself.

본 연구는 우리나라의 지적행정 및 지적교육 전반에 관한 현황과 문제점을 분석하고 미래지향적인 패러다임에 의한 지적행정 및 지적교육의 개선방안 제시를 목적으로 하고 있다. 개선 방향으로는 지적행정에 부동산관리행정을 융합한 토지행정으로 하였으며, 대학의 학과도 토지행정학과로 변경하고 이와 관련한 교육과정을 새로이 제안하였다. 토지행정의 범위는 토지등록을 기반으로 토지소유, 토지가격, 토지이용･개발(규제)로 하였다. 또한 이를 위한 행정조직체계와 토지행정학과의 교과목 및 공무원 직렬 및 국가기술자격의 개선을 제시하였다. The purpose of this study is to analyze the current status and problems of Cadastre administration and education in Korea and to present ways to improve Cadastre administration and education by future-oriented paradigm. The direction of improvement was to combine the intellectual administration with real estate management administration. And the department name was proposed to change as the department of land administration. The scope of land administration were land ownership, land price, and land use and development (regulation) based on land registration. In addition to that, to get the more effective administrative organization system, the improvement of the subjects of the Department of Land Administration, the series of public officials, and the national technical qualifications were presented in this paper.

황보율,김진택,김은기,강아람,오태정,장학철,박경수,김성연,이홍규,조영민 대한당뇨병학회 2012 Diabetes and Metabolism Journal Vol.36 No.2

Background: Latent autoimmune diabetes in adults (LADA) refers to a specific type of diabetes characterized by adult onset, presence of islet auto-antibodies, insulin independence at the time of diagnosis, and rapid decline in β-cell function. The prevalence of LADA among patients with type 2 diabetes varies from 2% to 20% according to the study population. Since most studies on the prevalence of LADA performed in Korea were conducted in patients who had been tested for anti-glutamic acid decarboxylase antibody (GADAb), a selection bias could not be excluded. In this study, we examined the prevalence and clinical characteristics of LADA among adult patients recently diagnosed with type 2 diabetes. Methods: We included 462 patients who were diagnosed with type 2 diabetes within 5 years from the time this study was performed. We measured GADAb, fasting insulin level, fasting C-peptide level, fasting plasma glucose level, HbA1c, and serum lipid profiles and collected data on clinical characteristics. Results: The prevalence of LADA was 4.3% (20/462) among adult patients with newly diagnosed type 2 diabetes. Compared with the GADAb-negative patients, the GADAb-positive patients had lower fasting C-peptide levels (1.2±0.8 ng/mL vs. 2.0±1.2 ng/mL, P=0.004). Other metabolic features were not significantly different between the two groups. Conclusion: The prevalence of LADA is 4.3% among Korean adult patients with recently diagnosed type 2 diabetes. The Korean LADA patients exhibited decreased insulin secretory capacity as reflected by lower C-peptide levels.

황보한,손진언 한국화학공학회 1967 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.5 No.1

An alternate procedure for the calculation of rotary-dryer is proposed, using the operating characteristics and the ratio of the time rate of heat capacity. The number of transfer unit in the period of constant rate of drying may be calculated from the knowledge of the humidity-increase in the dryer. Drying characteristic curves of ricebran are plotted from the experimental data and the diffusion data and the diffusion coefficients of the moisture in the ricebran are calculated. An example for the calculation of rotary-dryer is given.

최적 소프트웨어 양도 시간 추정을 위한 베이지안 접근 방법에 관한 연구

황보선애(Sunae Hwangbo),박상현(Sang-Hyun Park),박만곤(Man-Gon Park) 한국멀티미디어학회 2010 한국멀티미디어학회 학술발표논문집 Vol.2010 No.1

소프트웨어 테스팅(Software Testing)동안에 전체 개발노력의 상당한 부분이 소요되기 때문에, 적절한 소프트웨어 신뢰도 수준에서 소프트웨어 테스팅시간을 절약하면 많은 비용과 노력을 절감할 수 있다. 따라서 개발 소프트웨어 시스템에 대한 품질 평가측도로서 요구되는 신뢰도 수준까지 테스팅 하는 데 소요되는 최적시간, 즉 소프트웨어 테스팅을 종료한 후 사용자 또는 개발의뢰자에게 양도하는 최적양도시간(Optimal Release Time)을 결정하는 연구는 소프트웨어공학 분야의 중요한 과제로서 많은 연구가 수행되어져 오고 있다. 소프트웨어 최적 양도시간 결정은 소프트웨어 테스팅의 한 단계가 끝나고 나면 그 소프트웨어를 양도할 것인가 또는 계속 테스팅을 수행해야 할 것인가를 결정해야 하는 최적화 시간 결정 문제로서 스토핑 룰(Stopping Rule)이라 한다. 본 논문에서는 Forman과 Singpurwalla가 연구한 신뢰도계수를 미리 정하고 신뢰도 함수를 이용하여 대수적으로 최적 양도시간을 계산하여 결정하는 방법으로 초기 오류 개수와 실패강도의 추정을 베이즈 방법으로 접근하며 그 추정된 모수를 이용하여 베이지안 신뢰도함수를 구하여 그에 따른 요구 신뢰도 수준에 따른 최적의 양도시간을 결정하는 방법에 대해서 연구한다.
