The purpose of the study was to identify the latent classes of meta-awareness of gender discrimination among Korean young adults using Latent Profile Analysis based on 'perceived ambivalence toward men among women', 'perceived ambivalent sexism among men', 'perceived gender(reverse-) discrimination in Korea'. After identifying the latent classes, the difference between gender role conflict, sense of distance from the opposite sex, and support for gender discrimination issues were explored among the classified groups. As a result, 3 latent classes among women and 2 latent classes among men were identified. Latent classes among women were named 'women with low sensitivity of sexism', 'women with high sensitivity of sexism' and 'women against sexism' and latent classes among men were named 'men with perception of gender equality', 'men with perception of reverse discrimination'. Types with higher levels of meta-awareness of gender discrimination were related with higher gender role conflict and higher sense of distance from the opposite sex. Among women, types with higher levels of meta-awareness of gender discrimination perceived higher levels of gender discrimination and showed more support for gender discrimination issues while among men, types with higher levels of meta-perception of gender discrimination only perceived higher levels of reverse discrimination. Based on the present findings, implications about the severe gender conflict among Korean young adults are further discussed in the article.

This study was attempted to give aids in making 'the Disability Discrimination Act' by estimating the potential Cost-Benefit in case that the discrimination on the disabled is removed. The potential benefits from this Disability Discrimination Act are calculated considering the income increase of the people with disabilities from additional employment for them and the decrease of employment levies and the public assistance benefits. The potential cost was made focusing on the following 2 expenses- the extra expenditures that the owners of companies had to invest from the employment of the disabled and the managing expenses for correcting discrimination organizations. As the result of this estimation, the potential net present value under the 7% discount rate is very high as 12,700,301 million won and the cost-benefit ratio is also great as 96.8. The consequence of the sensitive analysis in changing the discount rate also does not have great changes. As the result of these estimating results, it is known that when the discrimination is solved by the 'Disability Discrimination Act', the pure benefit of our society will become tremendous. After all, it could be said that the need for 'the Disability Discrimination Act' is emphasized and should be emphasized.

The purpose of this study is to classify the degree of change of job discrimination of the disabled according to time and to identify factors affecting life satisfaction according to each type. For this study, data from the 3rd to 8th year of the employment panel for the disabled were used and 1,227 data were used. The longitudinal profile of the disabled person's discrimination was classified through latent profile growth analysis(LPGA), and then influential factors were verified through binomial logistic regression analysis. First, the types of change of the job discrimination of the disabled were represented as the decrease group and the increase group. The factors influencing the job discrimination were the degree of disability, chronic diseases, gross income, and life satisfaction. Second, the factors of predicting the life satisfaction according to the types of job discrimination of the disabled are as follows: job discrimination, decrease and increase group have higher life satisfaction as the self - esteem and socioeconomic status are higher. Based on these results, this study suggested the implications of this study to cope with the discrimination of the workplace with the disabled.

Discriminant analysis using near infrared spectra derived from Korean Flue-cured(KF) and American Flue-cured(AF), and also Korean Burley(KB) and American Burley(AB) tobacco was done to classify flue-cured and burley tobacco as either grown in Korea or grown in the USA. Samples were scanned in the wavelength of 400 ～ 2500 nm by near infrared analyzer(NIRSystem Co., model 6500). The discrimination equations for flue-cured and burley tobacco were developed using partial least square 2 method in Infrasoft International NIRS 3 software package. KF samples used for the development of the discrimination equations were higher contents of total sugar, crude ash and chlorine, and higher value of leaf density and brightness, but lower contents of nicotine, total nitrogen and ether extracts, and higher value of redness than those of AF samples. KB samples were higher contents of nicotine, crude ash and chlorine, but lower contents of ether extracts and value of brightness than those of AB samples. On 3 dimensional graph drawn with 3 principal component scores calculated with 3 principal component from KF and KB sample spectra, KF sample spectra were significantly different from AF, and also KB sample spectra were significantly different from AB. The discrimination equations of flue-cured and burley were developed with 3 principal component, respectively. The discrimination equations for flue-cured and burley had a standard error of 0.03 and 0.04, and a R2 of 0.88 and 0.84, respectively. The tobacco samples used for the development of discrimination equation were perfectly classified as KF and AF by flue-cured discrimination equation, and also perfectly classified KB and AB by burley discrimination equation, respectively. The correct classification rates of KF and AF samples not used for the development of discrimination equations were 9S % (828 out of 869 samples) and 98 % (98 out of 100 samples) by flue-cured discrimination equations, and KB and AB samples were 94%(345 out of 368 samples) and 100%(42 out of 42 samples) by burley discrimination equations, respectively.

In this paper, we propose an improved speech/music discrimination method based on a feature combination and dimensionality reduction approach. To improve discrimination ability, we use a feature based on spectral duration analysis and employ the hierarchical dimensionality reduction (HDR) method to reduce the effect of correlated features. Through various kinds of experiments on speech and music, it is shown that the proposed method showed high discrimination results when compared with conventional methods.

The discrimination of bracken (Korean vs. Chinese) has been attempted using capillary electrophoresis (CE). Bracken (Pteridium aquilinum) was extracted with 30% methanol and separated on a uncoated fused-silica ($50{\mu}m{\times}27cm$) capillary. Conditions for optimal analysis include: temperature, $40^{\circ}C$; voltage, 8 kV; and pressure injection time, 5 sec. The optimal separation buffer was 0.3 M borate buffer (pH 8.5) containing 40 mM CHAPS with 30% ethylene glycol. Under the optimal conditions established for CE, the ratio of specific peak area (peak PA-1) to other peak area (peak PA-2) was effective in discrimination of Korean and Chinese bracken. The mean accuracy for discrimination of Korean and Chinese brackens were 80% and 86%, respectively.

The purpose of this study is to investigate the factors that affect the discrimination of low-income children among children in the community children's centers. The subjects of the survey were 6th grade elementary school students who were the third respondents of the second Child Panel Survey of the community children's center, among them, 355 children whose family economy level corresponds to basic living allowance, next level, and blind spot. SPSS Statistics 25.0 was used to analyze exploratory factors, reliability analysis, frequency analysis, descriptive statistics, correlation analysis, and multiple regression analysis. The results of this study showed that single parent family, parent social capital, parental abuse, and happiness had a significant effect on the discrimination damage of low-income children in community children's centers. The more one parent's family, the less the parent's role as a counterpart to the discussion, and the more the parental abuse, the higher the child's discrimination damage. In general, parents-related factors were affecting the discrimination damage of low-income children. Community children's centers and related institutions should focus on developing and implementing programs that can improve the quality of family relations of children.

Owing to importance of document copyright the need to detect document duplication and plagiarism is increasing. Many studies have sought to meet such need, but there are difficulties in document duplication detection due to technological limitations with the processing of natural language. This thesis designs and implements a discriminator of similar documents with natural language processing technique. This system discriminates similar documents using morphological analysis, syntactic analysis, and weight on low frequency and idiom. To evaluate the system, we analyze the correlation between human discrimination and term-based discrimination, and between human discrimination and proposed discrimination. This analysis shows that the proposed discrimination needs improving. Future research should work to define the document type and improve the processing technique appropriate for each type.
