본 연구는 결혼이주여성의 차별경험과 삶의 만족도 사이의 관계를 확인하기 위한 연구이다. 본 연구는 A 도시의 다문화 가정 지원 센터를 다니는 108명의 결혼이주여성을 대상으로 설문조사한 조사연구로, 본 연구의 결과는 다음과 같다. 결혼이주여성의 차별경험의 평균은 2.15점, 삶의 만족도는 3.93점 이었다. 또한 차별경험과 삶의 만족도는 부적 상관관계를 가지고 있었다(r=-.289, p<.001). 결혼이주여성의 차별경험은 이들의 삶의 만족도에 유의한 예측인자로 나타났다(${\beta}=.312$, p=.030). 이러한 결과에 따라 본 연구에서는 결혼이주여성의 차별경험이 삶의 만족도에 영향 미치는 것을 나타났다. 그러므로 이러한 결과를 기반으로 결혼이주여성의 삶의 만족도를 향상시키기 위한 차별경험 조절 프로그램 연구를 제안한다.

Discrimination between speech and music is important in many multimedia applications. In our previous work, focusing on the spectral change characteristics of speech and music, we presented a method using the mean of minimum cepstral distances (MMCD), and it showed a very high discrimination performance. In this paper, to further improve the performance, we propose to employ time-averaged MFCC in computing the MMCD. Our experimental results show that the proposed method enhances the discrimination between speech and music. Moreover, the proposed method overcomes the weakness of the conventional MMCD method whose performance is relatively sensitive to the choice of the frame interval to compute the MMCD.

Auditory discrimination which represents a very basic and important perceptual skill in children is a necessary condition for effective learning. It is necessary, therefore, to devise a standardized test tool for a reliable assessment of the auditory discrimination ability of children. The Korean Auditory Discrimination Test(KADT) is a tentative test tool that the authors have devised to meet such demand, i.e., to test the auditory discrimination ability of Korean children, both normal and hearing- and speech-impaired, between the ages of 4 and 8. The KADT consists of 40 pairs of words arranged in a systematic manner, of which thirty are 'minimal pairs' of words and the rest homophonous synonyms. The 30 minimal pairs are composed in such a way that major phonological contrasts involving consonants and vowels at initial, medial and final positions are duly represented. The test score will be determined by the number of right responses made by the children. Further attempts will be made to refine and improve KADT in future.

The target of this study is development of web based mold discrimination system by matching vision information with CAD database. The use of 2D vision image makes possible speedy mold discrimination from many databases. The image processing such as preprocessing, cleaning is done for obtaining vivid image with object information. The web-based system is a program which runs to exchange messages between a server and a client by making of ActiveX control and the result of mold discrimination is shown on web-browser. For effective feature classification and extraction, signature method is used to make sensible information from 2D data. As a result, the possibility of proposed system is shown as matching feature information from vision image with CAD database samples.

Spectroscopic analysis of soybean kernels were made in the wavelength range of 400 to 1100 nm to find effective discrimination factors which are required for developing an opitical soybean sorter. Soybean samples used for the test were the sound and five classes of the defective kernels such as the immature, discolored(brown and violet), damaged by insect and diseased. Effective discrimination factors to classify the soybean kernels into the sound and the defective were found to be $R_{640}$, $R_{580}$/ $R_{990}$, $R_{600}$- $R_{820}$ and ( $R_{590}$- $R_{820}$)/ $R_{990}$. with classification error of less than 4%. Mahalanobis distance was used as a criterion to select significant wavelengths involved in the discrimination factors.s.

지방 출신은 서울/경기 출신에 비해 임금이 낮다. 이 차이가 기호적 차별에 기인하는지 또는 통계적 차별에 기인하는지를 판별하기 위해 임금격차에 대한 계량경제학적 모형을 제시했으며 그것을 이용하여 검정하였다. 이에 따르면 출신지역간 임금격차가 온전히 기호적 차별에 기인한다는 가설은 한계적으로 기각되었다. 즉 이 격차의 일부는 통계적 차별에 기인한다. 본고의 통계적 차별은 임금이 생산성에 따라 결정되는 과정에서 나오는 것으로 문제가 되지 않으므로 정부가 개입할 필요가 없다.

Purposes: The purpose of this study was to analyze the association between discrimination experience and quality of life among non-regular workers in hospitals. Methodology: The data was collected from 292 employees of 7 university hospitals using a standardized questionnaire. In research methodology, the data was analyzed with descriptive statistics, t-test, ANOVA, pearson's correlation, multiple regression analysis. Findings: In case of non-regular workers, inequality of distribution, position unfairness, employment instability, number of discrimination experiences were found to have a negative(-) effect on quality of life. Religion, income in general characteristics had a significant positive(+) effect on quality of life. And the discrimination of non-regular woman workers was higher and the quality of life was lower than that of men. Practical Implications: These results showed that hospitals needed active efforts to create non-regular woman-friendly work environment. In addition, active religious activities gave emotional stability and positive effect to no-regular workers.

This study explored the discrimination of synthesized English vowel pairs by twenty-seven American and Korean, male and female listeners. The average formant values of nine monophthongs produced by ten American English male speakers were employed to synthesize the vowels. Then, subjects were instructed explicitly to respond to AX discrimination tasks in which the standard vowel was followed by another one with the increment or decrement of the original formant values. The highest and lowest formant values of the same vowel quality were collected and compared to examine patterns of vowel discrimination. Results showed that the American and Korean groups discriminated the vowel pairs almost identically and their center formant frequency values of the high and low boundary fell almost exactly on those of the standards. In addition, the acceptable range of the same vowel quality was similar among the language and gender groups. The acceptable thresholds of each vowel formed oval to maintain perceptual contrast from adjacent vowels. The results suggested that nonnative speakers with high English proficiency could match native speakers' performance in discriminating vowel pairs with a shorter inter-stimulus interval. Pedagogical implications of those findings are discussed.

The main purpose of this study was to examine the impact of increasing morale on social support and discrimination. The relationship between discrimination and social support and their influences on the morale of the elderly was investigated, with the goal of raising morale in the elderly. The data were collected from a sample of 574 elderly people in Daejeon Metro-City. Factors positively influencing the morale of the elderly were identified a shaving a partner, a high educational background, financial status, good health status, the presence of an informal support from friends and neighbors, and less feeling of discrimination. Based on these findings, implications for social welfare policy and future research are discussed.

In this paper, the linear autoregressive model of EMG signal for four basic arm functions was presented and parameters for each function were estimated. The signal identification was carried out using function discrimination algorithm. It was validated that EMG signal was a widesense stationary process and the linear autoregressive model of EMG signal was constructed through approximating it to Gaussian process. It was confined that Levinson-Durbin algoridthm is a more appropriate one than the recursive least square method for parameter estimation of the linear model. Optimal function discrimination was acquired when sampling frequency was 500Hz and two electrodes were attached to bicep and tricep muscle, respectively. Parameter values were independent of variance and the number of minimum data for function discrimination was 200. Bayesian discrimination method turned out to be a better one than parallel filtering method for functional discrimination recognition.
