In order to obtain the fundamental data on the underwater sound of fishes for marine ranching. The underwater sound of Red Seabream(Pagrus major) and Schlegel's black rockfish(Sebastes schlegeli) were measured, which character were summarized by FFT analysis.

교회음악은 보다 넓은 뜻에서 그리스도교 신앙 안에서 작곡된 모든 음악 곡들을 포함하지만, 전례음악(성음악)은 하느님께 예배를 올리는 식전 즉, 전례를 위해서 작곡된 음악을 뜻합니다. 결과적으로 애초부터 연주회를 목적으로 작곡되었다든지 일반 기도모임이나 혹은 신자 단체의 결속을 위해서 만들어진 노래들은 교회음악에는 들어가지만 성음악은 아닌 셈입니다.

Drinking Problems among college students have been increasing and being severe social problems. When it is compared with other areas, the research about drinking problems of college students are rare. This study was to examine psychosocial factors influencing on problem drinking among college students. The sample size of this study was 414, which made it possible to do statistical inference. AUDIT was applicated to measure the drinking problems in college student. As statistical method, $X^2$-test, t-test, hierarchial multiple regression analysis were used. The main finding provided that drinking problem of college students was more severe than adult one. Especially binge drinking pattern was remarkable. Male student had many alcohol problems than female students. This study also revealed gender, religious activity, first drinking age, sensation -seeking, drinking motivation, parents' drinking problem, schoolwork record, peer influence had significant direct impact in problem drinking of college students. Based on the results of this study, the author suggested some practical implication and preventive program based on the results and added further study tasks.

A simple algorithm for discriminating voiced sounds in a speech is proposed in this paper. In addition to low-frequency energy and zero-crossing rate (ZCR), both of which have been widely used in the past for identifying voiced sounds, the proposed algorithm incorporates pitch variation to improve the discrimination rate. Based on TIMIT corpus, evaluation result shows an improvement of 13% in the discrimination of voiced phonemes over that of the traditional algorithm using only energy and ZCR.

수중폭발성음원인 SUS(signal underwater sound)는 수중에서의 폭발과 동시에 충격파와 기포파들이 연속적으로 발생한다. 이러한 신호는 광범위한 주파수대역을 가지고 전파거리가 길어지면서 굴절과 반사등의 다중경로 전파효과에 의한 신호의 변형까지 생긴다. (1,2,3). 본 연구에서는 deconvolution 방법을 이용하여 수신신호중에서 기포파효과를 최소화시켜 충격파의 수신기 도달시간을 파악하고, 각 충격파들의 전파경로를 추정하여 이 중 직접경로와 해저면 반사경로의 신호를 이용하여 해저면 반사계수를 계산하였다.

The purpose of this study is to examine the effects of Pansori creative therapy focusing on a vocal sound on the self-efficacy of older adults living alone. Participants were 6 aged people who were living alone and who attended S Welfare Center for aged people. Pansori creative programs were provided twice a week for 6 weeks. The program consisted of 5 stages that had 50 minutes for each section. Quantitative data were collected from a pre-and post-self-efficacy scale (Park, Gyung-min, 1994) in order to confirm the changes in self-efficacy of the participants. Results showed statistical significance in self-efficacy scores (p < .05). In addition, positive verbal comments on decreased performance anxiety were found from participants during interviews conducted after the completion of Pansori creative program.

In this study, we research the robust speech recognition for the syllables and phoneme units with the feature parameter including the voiced-unvoiced measures for the confusable words. In order to make it possible, we propose the measure representing the voiced-unvoiced degree by using the HPS(Harmonic Product Spectrum) information, used on pitch detection. We proposed this measures with the sharpnes, peak count and height measure of HPS. We reconstructed the feature parameter including this measures, then we performs the speech recognition experiments and compared with the typical feature parameters under the CVC type confusable syllables DB.
