慶尙南道 市地域 民間醫院의 母子保健事業 推進實態 및 그 改善에 關한 調査硏究
金柄成,金公鉉,金炳星,朴亨鐘 대한보건협회 1992 대한보건연구 Vol.18 No.2
This study was carried out to review the current status of maternal and child health care (MCH) program implemented by the private clinics located in the cities in Kyungnam Province and to suggest alternative approaches to improve their on-going programs through a self-administered questionnaire. The subjects were 185 private physicians who operated their own clinics since 1990 and were general practitioner. Obstetrician/Gynecologist, or pediatrician. The survey was conducted by mail from 15 January to 25 February 1992. The response rate was 70.8 percent. Major results were as follows: 1. The major manpower for MCH of the studied clinics was physicians and nurse-aids. 32% of those employed one or more lab-technicians. No clinics had an independent building for MCH program. Most of studied clinics did not adequately install medical and laboratory equipments for MCH program except some of Ob/Gyn clinics. 2. 51.9% and 46.6% of the studied clinics did not provide consulting services and curative services to patients in relation to MCH respectively. 74% of them did not also provide any laboratory services. 3. Pre-and post-natal care services were provided in most Ob/Gyn clinics and general practitioners while growth measurement and immunization services were done in pediatric clinics. 4. 33% of the studied clinics had been opening either regular or irregular health education sessions for MCH. Ob/Gyn clinics put emphasis on clinical management and physiology of pregnancy and preparing delivery, but pediatric clinics did on infant rearing and immunization. 45% of the studied clinics had some kinds of health education materials for MCH program. 5. Blood presure, glucosuria and blood type were tested in 65% of the studied clinics:Ultrasonography and tests for hepatitis and fetal heart rate were provided in 40%: and tests for uterine cancer, gonorrhea and sypilis in 30%. Those tests were almost provided by Ob/Gyn clinics. 6. There were less than 10% of clinics which had been supported with drugs, equipments, or culture media for MCH programs from the government. Even though the government supply those materials to them free of charge to encourage their involvement, 40% of Ob/Gyn clinics and each 56% of general practice and pediatric clinics replied not to engage MCH programs linked with the Health Center.

김병성,Kim, Byung-Sung 대한전자공학회 1999 電子工學會論文誌, D Vol.d36 No.2
FET 소신호 모델의 직접추출법은 기생소자값을 구하기 위해 주로 순방향 소동(cold) FET 조건을 이용하고 있다. 본 논문은 수동 FET 조건에서 해석적 채널모델을 유도하고, 정상수동 소자 조건에서도 순방향 수동 FET 조건과 동일 한 정보를 얻을 수 이Tdmadmff 보인다. 이와 함께 수동 FET 조건에 의해 제한되는 능동 FET 소신호 모델의 오차를 추적하여 수동 FET 방법을 이용한 직접 추출 모델의 오차 한계를 살피고, 오차 최소점의 유무를 통해 수동 FET 기생저항값의 유효성을 검토한다. Direct extraction of FET's small signal model parameters needs predetermined parasitic elements usually obtained under forward cold FET conditionl This paper derives analytic intrinsic model for cold FET's and shows that normal cold FET condition can replace forward cold FET condition for extracting parasitic elements. Then, we track the error of hot FET's small signal model bounded by the cold FET condition and examine the validness of cold parasitic resistances by checking the existence of the error minimum.

Health-related Quality of Life and Related Factors in Full-time and Part-time Workers
김병성,김원준,최현림,원장원,김영신 대한가정의학회 2012 Korean Journal of Family Medicine Vol.33 No.4
Background: There has been a rapid increase in the number of part-time workers in Korea with little information available on associated changes in quality of life. This study was designed to compare part-time and full-time workers in terms of the quality of life and related factors. Methods: Data were extracted from the 4th Korea National Health and Nutrition Examination Survey, conducted in 2008. Of the 1,284 participants selected, 942 were females (range, 20 to 64 years). Based on the information provided by selfadministered questionnaire, subjects were categorized according to the working pattern (full-time and part-time) and working hours (<30 and ≥30 hours). Differences in socio-demographic characteristics, health-related behaviors, and job characteristics were assessed by t-test and chi-square test. EuroQol-five dimensions (EQ-5D) index was implemented in order to measure the quality of life. Differences in the EQ-5D index scores between the groups were compared by t-test,stepwise multivariate logistic regression analyses. Results: Quality of life did not differ by work patterns. In males, the Organization for Economic Cooperation and Development part-time group was associated with poorer quality of life (odds ratio [OR], 0.49; P = 0.028). For both sexes,the non-stress group was linked with superior quality of life in comparison to the stress group (OR, 2.64; P = 0.002; OR, 2.17;P < 0.001). Female employees engaged in non-manual labor had superior quality of life than those engaged in manual labor (OR, 1.40; P = 0.027). Conclusion: This study concludes that working less than 30 hours per week is related to lower quality of life in comparison to working 30 hours or more in male employees in Korea.

부호화된 다중 선형 처프 기반 통신 유사 재밍의 아군 통신 성능 분석
김병성,신요안 한국통신학회 2022 한국통신학회 학술대회논문집 Vol.2022 No.2
본 논문은 기존 연구되었던 단일 선형 처프 기반 통신 유사 재밍에서, 더 나은 아군 통신 성능 분석을 도출하기 위해 다중 선형 처프 기법에 부호화를 이용한 코드화 기법을 적용하여 아군의 비트오율 통신 성능을 비교 분석한다. 단일 선형 처프 신호에서 코드화 기법이 가장 좋은 성능을 보였으며, 다중 선형 처프 기법에 적용할 시 가장 좋은 성능을 도출할 것으로 예상하였고 이를 모의실험을 통해 확인하였다.
