IRT Filtering 법에 의한 음성신호의 기본주파수 수출
배명수,안수길 한국음향학회 1986 韓國音響學會誌 Vol.5 No.3
음성 신호 처리분야에서 고속이며 정확히 기본 주파수를 추출하는 방법은 중요하며, 이를 위한 많은 연구가 제안되어 왔다. 이러한 방법들은 보통 성도의 방해를 제거한 후에 기본 주파수를 검출하기 때문에 지금까지는 처리과정이 복잡하다. 우리는 그러한 과정을 간단히 처리할 수 ldt는 inverse rate type filtering 법을 제안하였다. 제안된 방법은 유한 길이의 정수 계산이고 덧셈과 뺄셈으로 처리될 수 있기 때문에 범용 마이크로 컴퓨터에 의해서도 실시간 처리를 할 수 있게 된다.
Spectrum 강조특성을 이용한 음성신호에서 Voicd - Unvoiced - Silence 분류
배명수,안수길 한국음향학회 1985 韓國音響學會誌 Vol.4 No.1
In this paper, we describe a new algorithm for deciding whether a given segment of a speech signal is classified as voiced speech, unvoiced speech, or silence, based on parameters made on the signal. The measured parameters for the voiced-unvoiced classfication are the areas of each Zero crossing interval, which is given by multiplication of the magnitude by the inverse zero corssing rate of speech signals. The employed parameter for the unvoiced-silence classification, also, are each of positive area summation during four milisecond interval for the high frequency emphasized speech signals.

The object of this research checked the relationship of the family situation factors about the Daegu and Gyeongbuk teenager drinking and I examined the sex difference about that relationship. Especially the dangerous drinking and problem drinking rate and woman of which the problem drinking rate rises analyzed the dangerous drinking and cause in which the problem drinking rate is higher at the class switch than the man. it could know to be the common factor which a can be danger drink if the part-time job experience, the last academic background of their father and mother had man and woman altogether. the problem drinking factor was analyzed as a discriminative factor about the grade had man and woman altogether. I could know that when woman sees the man in the problem sound main cause, then the various factors are acting more much but the common factors is having an effect so that the problem sound week factors can be altogether overlapped with man and woman. as this result, male and female didn`t gave distinction of sex as generation homogeneity is same on both side. however, problem drinking and dangerous drinking increased much more when they were getting older.

The purpose of this study is to highlight the adolescent alcohol use disorder(AUD) during the transition from middle school to high school periods, and attempt to assess the socioeconomic context associated with adolescent AUD. In this study, we examined AUD in terms of binge drinking and problem drinking. From the original the data of 2012 Adolescent Online Behavior Survey, we recruited 5,928 respondents of middle to highschool students who reported to have alcohol experience. Sex is treated separately in our analysis. Result shows the upward trend of binge drinking and problem drinking by school year, for both gender. Male adolescent show higher prevalence in binge drinking compared to female adolescent. However, the female adolescent show slightly higher proportion in suffering problem drinking compared to their counterparts. In out study, adolescent``s paid-work experience is the main driver associated with binge drinking for both gender. As for the problem drinking, parental education, subjective economic status, the amount of adolescent``s pocket-money were associated with problem drinking. Especially for female adolescent, living arrangements, having depressive symptom, attitude toward suicide trial, and academic achievement is also found to be relevant with problem drinking behavior.
