박성효,최영민,조세진 대한산부인과학회 2000 Obstetrics & Gynecology Science Vol.43 No.8

We have undertaken this study to identify the factor VIII gene inversions in Korean patients with severe hemophilia A. We have analyzed the presence of factor VIII gene inversions in 41 unrelated Korean patients with severe hemophilia A, using Southern blot analysis. Factor VIII gene inversions were noted in 16 (39%) out of 41 patients studied: thirteen patients (31.7%) had a type 1 (distal) factor VIII gene inversion, and three patients (7.3%) had a type 2 (proximal) factor VIII gene inversion. Carrier detection was performed in three sisters of patients who showed type 1 factor VIII gene inversions: two sisters had a type 1 factor gene inversion, the other sister had no inversion. These data suggest that factor VIII gene inversion is found in about 40% of Korean patient with severe hemophilia A, and that the detection of factor VIII gene inversion is very useful for carrier detection and prenatal diagnosis of hemophilia A in the Korean population as well as in Caucasians.

This study researched the dietary habit of boy's and girl's high school students, and into low it was connected with the state of health between the group of having the right dietary habit and the group of having the wrong habit. Results were as follows: 1. The age about the object person of research was the most numerous in 79% at 16∼17 years old, the average weight was 55.67±9.08 ㎏, the average height was 165.47±7.56㎝. 2. In the parent's school career of the object person of research, persons who graduated high school were many. The mother's educational level was lower than the father's school career. The parent's school career in the district south of a river was higher than the parent's school career in the district north of a river. And the parent's school career of cultural students was high. 3. The frequency of food intake in the district north of a river and in the district south of a river was a meaningful difference in the vegetables blended in green and yellow things(p< .01), fruit (p< .05), rice, flour, potatoes (p< .05), and so the district north of a river took less than the district south of a river. 4. The most regular diet in a day was lunch, The appetite of the students was generally good. 5. The general environment and state of health were a meaningful difference about melancholia (p< .05) in the district of north and south of river, and so melancholia in students of the north of a river was high. 6. The state of health according to regular diet was a meaningful difference, so regular student was better than irregular student in state of health, and was the same in study. 7. Eating habit correlated much to each state of health, Especially in physical health, the muscular frame correlated to fruit (p< .001), seaweeds (p< .05), fried food, jun, panbroiled food (p< .05), salty taste (p< .05), sour taste (p< .001).

Facile Li⁺ ion transport and superior thermal stability of polydopamine-encapsulated graphite anodes for Li-ion batteries

박성효,이호춘 한국공업화학회 2014 한국공업화학회 연구논문 초록집 Vol.2014 No.1

Polydopamine (PD) coating is demonstrated to enhance Li+ ion transport kinetics and thermal stability of graphite anode for Li-ion batteries. Commercial grade graphite electrodes are successfully coated with nano-scale PD layer by simple dip-coating process. PD-coated graphite electrodes exhibit increased initial reversible capacity and improved rate capability at both lithiation and de-lithiation processes. The superior power performance of PD-coated graphite is ascribed to the reduced activation energy for the interfacial Li+ transfer reaction, as evidenced by the electrochemical impedance spectroscopy (EIS) measurements. In addition, PD-coated graphite show improved cycle performance at 60°C, which is attributed to suppressed thermal degradation of the graphite/electrolyte interface by PD coating.

Adaboost를 이용한 모바일 환경에서의 홍채인식을 위한 눈 검출에 관한 연구

박성효(SungHyo Park),조달호(Dalho Cho),박강령(Kang Ryoung Park) 대한전자공학회 2008 電子工學會論文誌-CI (Computer and Information) Vol.45 No.4

본 논문에서는 adaboost(adaptive boosting)를 이용한 눈 검출 알고리즘을 제안한다. 또한 기존의 adaboost를 이용한 눈 검출 알고리즘의 문제점으로 지적된, 실제 눈이 아님에도 불구하고, 눈으로 찾는 오검출율(false alarm rate)를 감소시키기 위해 각막 면에 생성되는 조명의 반사광을 모델링을 통해 추정하고 adaboost의 학습과 눈 검출에 사용되는 박스의 최적의 크기를 실험을 통해 결정하였다. 위의 결과로 검출된 눈 영역을 중심으로 일정 영역에 대하여 동공과 홍채 영역을 원형검출기(circular edge detector)를 이용하여 검출하였다. 실험결과 휴대폰으로 취득한 얼굴영상에서 약 99%의 눈 검출 정확도를 나타내었으며, 휴대폰 환경에 적용했을 때 처리시간은 1초 내외 소요됨을 알 수 있었다. In this paper, we propose the new eye detection method by using adaboost (adaptive boosting) method. Also, to reduce the false alarm rate which identifies the non-eye region as genuine eye that is the problems of previous method using conventional adaboost, we proposed the post processing methods which used the cornea specular reflection and determined the optimized ratio of eye detecting box. Based on detected eye region by using adaboost, we performed the double circular edge detector for localizing a pupil and an iris region at the same time. Experimental results showed that the accuracy of eye detection was about 98% and the processing time was less than 1 second in mobile device.

Insulated Metal Substrate의 Top Metal과 Bottom Metal 두께 변화에 따른 전력 모듈 열 방출 특성 분석

박성효(Seong-Hyo Park),정봉민(Bong-Min Jeong),오애선(Ae-Seon Oh),김선애(Seon-Ae Kim),석오균(O-Gyun Seok),배현철(Hyun-Cheol Bae) 대한전자공학회 2023 대한전자공학회 학술대회 Vol.2023 No.6

Direct Bonded Copper (DBC) commonly used in Power Module can cause cracks due to the Coefficient of Thermal Expansion (CTE) mismatch between Cu and ceramic. Insulated metal substrate (IMS) are proposed to overcome these disadvantages of DBCs. Unlike the existing IMS Power module, it introduces the integrated structure of bottom metal and base plate. The dielectric of IMS has a lower heat dissipation capacity than the ceramic of DBC due to the low thermal conductivity of the dielectric, but to overcome this, the heat dissipation ability is improved by changing the thickness of the top metal and bottom metal. In this paper, thermal analysis simulation is conducted using COMSOL MULTIPHYSICS. Compared to DBC substrates using Al2O3 Ceramics, the top metal thickness of the IMS substrate is changed to 0.3mm to 2.5mm, and the heat dissipation ability is observed accordingly. In addition, the bottom metal thickness is changed to 3mm to 5mm and observed. The thicker the thickness of the top and bottom metal, the better the heat dissipation ability.
