만성 반복성 두통 환아에서 간질양 뇌파 소견에 대한 연구
배윤진(Yun Jin Bae),최진성(Jin Sung Choi),황규근(Kyu Geun Hwang) 대한소아신경학회 2006 대한소아신경학회지 Vol.14 No.1
목 적: 만성 두통 환자에서 뇌파 검사상 일반인에 비해 간질양 이상 뇌파의 출현율은 높지만, 이에 대한 조사는 적다. 이에 저자들은 만성 두통시 동반되는 간질양 이상파에 대한 출현 양상과 의의를 조사하고자 하였다. 방 법: 1999년 1월 1일부터 2005년 7월 1일까지 만 6년 6개월간 1개월 이상의 비진행성, 반복성 두통을 주소로 동아대학교병원 소아과를 방문하였던 환아 449례 중 뇌파검사를 시행하였던 336례 중 간질양 이상파를 보였던 36례를 대상으로 하였다. 2004년도 국제두통학회의 분류에 의해 두통을 분류하였으며, 뇌파 검사는 두통 간헐기에 시행하였고, 안정 각성시, 수면, 광자극 및 과호흡 유발을 포함하여 검사하였다. 만성 두통형에 따른 간질양 이상파의 출현율, 간질양 이상파의 출현부위, 출현빈도, 이상파의 파형, MRI 소견 및 간질 동반 유무를 조사하였다. 결 과: 만성 두통시 간질양 이상 뇌파의 출현빈도 10.7%로 정상인의 빈도에 비해 높았다. 간질양 이상 뇌파의 출현 부위는 국소성(9.2%)이 전반성(1.5)%에 비해 많았다. 두통의 병형별로 간질양 이상 뇌파의 출현 빈도는 의미있게 차이가 있었다. 국소 뇌파 이상은 중심 측두부(61.1%)에 가장 많이 관찰되었다. 간질양 이상파의 출현 양식은 빈번한 출현이 63.9%로 다른 출현 양식에 비해 많았으며 간질양 이상파의 파형은 국소 극파형(83.3)%이 가장 많이 관찰되었다. 간질양 이상파를 보인 환아 36례 중 2례(5.6%)에서 추적 검사상 간질을 나타내었다. 간질양 이상파를 보인 소아 36례 중 2례(5.6%)에서 MRI검사에서 이상 소견(AV malformation)을 보였다. 결 론 : 만성 두통시 나타나는 간질양 이상파는 주로 중심 측두부에 국소성의 산발성 극파 양상의 양성의 형태를 나타내나 극히 일부에서 간질이나 뇌이상이 동반 될 수 있기 때문에 추적 관찰이 필요하다. Purpose : This study was undertaken to determine the incidence and the meaning of epileptiform discharges accompanied by chronic recurrent headaches. Methods : We selected 449 cases of children who visited Dong-A University Hospital because of recurrent headaches from January 1999 to July 2005. The headaches were classified by the criteria established by the International Headache Research Committee in 2004. The electroencephalography was performed in 336 cases and 36 cases who showed epileptiform discharges were selected. We studied the characteristics of epileptiform discharges, MRI findings and the relationship with epilepsy. Results : The incidence of interictal epileptiform discharges(ILEDs) of the patients with chronic headaches was 10.7%, which was higher than that in a normal population. In the location of ILEDs, focal areas(9.2%) were more common than general areas(1.5%). The incidence of the ILEDs was different according to the types of headaches(P<0.01). The focal ILEDs were concentrated at the central temporal areas. The most common type of ILEDs was frequent epileptiform discharges(63.9%). For the wave forms of ILEDs, focal spike activities were 83.3%, and bursts of slow waves mixed with spikes were 13.9%. Among the 36 cases that showed the ILEDs, 2 cases were associated with epilepsy and another 2 with AV malformation on the MRI images. Concl usi on : The ILEDs of the patients with chronic recurrent headaches mainly occurred in the central temporal areas as focal spike wave forms, which shows a benign course. Because a few cases can accompany epilepsy and brain abnormalities, close observation and follow-up tests are needed.

주파수 영역에서 움직임 예측을 이용한 디지털 홀로그램 압축 기법
배윤진(Yun-Jin Bae),최현준(Hyun-Jun Choi),서영호(Young-Ho Seo),김동욱(Dong-Wook Kim) 한국방송·미디어공학회 2010 한국방송공학회 학술발표대회 논문집 Vol.2010 No.7
본 논문에서는 기존의 2차원 영상/비디오 압축 기술을 홀로그램의 특성에 적합하게 변형시켜서 홀로그램 데이터를 압축하는 압축 기법을 제안하였다. 컴퓨터 생성 홀로그램(computer generated holograms, CGH) 기법을 이용해 생성한 디지털 홀로 그램을 사용하였다. 본 논문에서는 전처리된 디지털 홀로그램에 대해 분할, 주파수 변환, 움직임 예측과 주파수 영역에서의 잔여영상 생성 기법을 적용하여 데이터 압축을 수행한다. 압축은 H.264/AVC, 무손실 압축기법인 BinHex와, 선형 양자화를 이용하였고, 실험 결과를 보면 제안한 데이터 압축 기법은 전체 압축률이 10:1~90:1까지 변화함에따라 25.4dB~16.5dB로 감소함을 확인할 수 있다. 그러나 시각적인 영상의 품질은 앞서 제시한 PSNR값 보다 훨씬 우수함을 확인 할 수 있다.

This study explored the relationships between parenting behavior preschooler`s effortful control and social adjustment. The subjects were 351 preschoolers(174 boys 177 girls) and their parents. The major results of this study were as follows. First there were significant relationships among the factors analyzed in this research namely affectionate parenting behavior preschooler`s effortful control and social adjustment. Second preschooler`s effortful control mediated the effects of affectionate parenting behavior upon preschooler`s social adjustment. In conclusion this study revealed that parents` affectionate parenting behavior and a preschooler`s effortful control make a significant impact on the level of the preschooler`s social adjustment. Based on th findings of this investigation the implications of the preschooler`s effortful control were also discussed.

의도적 통제(Effortful Control) 관련 논문의 연구 동향
배윤진(Bae, Yun Jin),임지영(Lim, Ji Young) 한국생활과학회 2011 한국생활과학회지 Vol.20 No.1
The purpose of this study was to analyze the research trends on effortful control with a focus on those found in academic journals. This was done in an attempt to understand the conception of effortful control clearly and lay the foundations for future studies. An analysis was performed on frequencies by years, methodology, and content. Results showed that (1) 95 research articles on effortful control were published between January of 1999 and June of 2010. (2) Most research participants were school-aged children. (3) There were a number of ways that researchers have assessed the concept of effortful control, and the most frequently used measurement scale was the Rothbarts questionnaire for temperament. (4) The main content of the research was the relationships between effortful control and developmental domains (particularly, emotional and social development). More recently, researches examining environmental factors including family and peer environment have increased.

Second, preschooler`s effortful control mediated the effects of affectionate parenting behavior upon preschooler`s prosocial behavior. Third, preschooler`s effortful control had direct effects upon prosocial behavior, and prosocial behavior mediated the effects of preschooler`s effortful control upon cognitive problem-solving ability. In conclusion, parents` effortful control and affectionate parenting behavior impacted upon preschooler`s effortful control. And preschooler`s effortful control had an important role upon prosocial behavior and cognitive problem-solving ability.

부모의 의도적 통제 및 양육행동과 영아의 의도적 통제 간의 관계
배윤진 ( Yun Jin Bae ),임지영 ( Ji Young Lim ) 대한가정학회 2012 Human Ecology Research(HER) Vol.50 No.2
This study was conducted to study the associations between parents` effortful control (EC), their parenting behavior and infants` EC. Subjects of the present study were 55 infants and their parents. Parents who participated in this study replied to questionnaires, including ECBQ-SF, ATQ-SF and Parenting style scale. There was positive correlations between the parents` EC, affectionate parenting style and infants` EC by zero-order correlation. We also performed Mann-Whitney test on the acquired data and it showed significant differences in the infants` EC by their parents` EC and parenting behavior. More specifically, infants with more affectionate and permissive parents showed higher levels of EC. Finally, we performed a partial correlation analysis and its results revealed that the correlation coefficient between the parents` EC and the infants` EC decreased when the parenting style was controlled. These results are vital to have a better understanding on the developmental pathways to the EC.
