This study aimed to examine the sexual discrimination in the labor market. For this purpose, this study compared the work conditions, perception of sexual discrimination in the work place and job satisfaction by sex, and showed some effects of the independent variables on the two dependent variables; the perception of sexual discrimination in the work place and job satisfaction. The data were from KLFI(1995)'s National data and two OLS (Ordinary Least Square) Regression models were used. The results of this study were as follows. There were significant differences in the working conditions between two sex groups. The perception of sexual discrimination in the work place was a little low and the difference by sex was not found. The variables related to the work were more important to predict the perception of sexual discrimination in the work place rather than the general characteristics of the sample. The male workers were more satisfied with their work than the female workers. The satisfaction of their work was significantly different by the variables related to the work.

Background: In Korea, little research has focused on the relationship between discrimination in the workplace and sleep health. Thus, this study aims to investigate the association between such discriminatory experiences and insomnia, a common sleep disorder, using Korean employees' data. Methods: This study used data from the 6th Korea Working Conditions Survey. Discrimination experiences due to age, ethnic background, nationality, race, sex, religion, disability, sexual orientation, educational level, hometown, and employment status were investigated. The Minimal Insomnia Symptom Scale estimated insomnia symptoms. The association between discrimination experience and insomnia symptoms were analyzed using survey-weighted logistic regression analysis. Results: Based on experiences of discrimination over the past 12 months, insomnia symptoms were associated with discrimination experience due to religion (odds ratio [OR]: 3.70; 95% confidential interval [CI]: 1.58-8.69), sex (OR: 2.51; 95% CI: 1.87-3.37), age (OR: 2.30; 95% CI: 1.88-2.81), hometown (OR: 2.07; 95% CI: 1.44-2.97), employment status (OR: 1.69; 95% CI: 1.37-2.10), and educational level (OR: 1.67; 95% CI: 1.31-2.14). Furthermore, the prevalence of insomnia symptoms increased with the number of discrimination experiences. Conclusions: In this study, discrimination experiences due to religion, sex, age, hometown, employment status, and educational level were significantly associated with insomnia symptoms. Furthermore, as the number of discrimination experiences increased, so did the prevalence of insomnia. Preventing workplace discrimination may improve workers' sleep health.

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.

To produce F1 hybrid of silkworm sex discrimination has to be followed at the pupal stage by sexual organ. However it requires a lot of labour and may bring about a wrong classification. In these regards, this study has been implemented to find out an effective measure for the pupal sex discrimination by use of variation of cocoon weight and image analysis of cocoon. As a result, it was found that in case of the pupal weight the percentage of a wrong classification fell on 0.3% and in case of single cocoon weight 0.4%. The discrimination rate was 99% in the weight variables of cocoon but analysis by single cocoon weight and cocoon shape variables, it was 98.7%. Efficiency of discrimination was increased by 2.7% as compared to variable of single cocoon weight. The minimum cocoon sampling size may be 15 cocoons sexual-wise.

Common finch is a kind of ornamental birds and could not distinguish male and female birds. For sex discrimination of Common finch, we investigated 400 birds of Common finch using the anatomical differences of Pars intermandibularis and traditional methods that currently used at the farms. Both methods have the sex determination accuracy of 48.82 and 46.0 ％ that the anatomical difference method seems little higher results than the traditional methods. More researches is needed for improving the sex determination accuracy.

The main purpose of this study is to explore the determinants of sex ratio imbalance at birth in Taegu which has experienced the extremely imbalanced sex ratio at birth since mid-1980s. This paper attempts to compare the determinants of sex ratio imbalance at birth, such as sex discrimination against women, son preference, prenatal sex identification followes by sex-selective induced abortions, among married women aged 25 to 44 in Taegu with those in Bay area, California in USA. The research is based on the survey data which were conducted in Taegu, Repulic of Korea and Bay area, California in USA. The findings of this analysis suggest that married women in Taegu are more likely to feel sex discrimination against women than married women in Bay area. Furthermore, the percentage of married women's effort for son bearing before pregnancy is much higher than that of married women in Bay area. We also have found that the percentage of sex-selective induced abortion in Taegu is six times higher than that of married women in Bay area. According to the logistic regression analysis, the determinants of sex-selective induced abortion among married women in Taegu are discrimination against women, son preference, prenatal sex identification. On the other hand, age is the only variable which has an important impact on sex-selective induced abortion among married women in Bay area. From the findings of this study, we can conclude that son preference based on Cofucianism is the most important impact on sex ratio imbalance at birth in Taegu where son preference is much stronger than other regions in Korea. The phenomenon of extremely imbalanced sex ratio at birth in Taegu is the result of combination of these factors, such as strong son preference, seeking to have at least one son within small family size, and prenatal sex identification followed by sex-selective induced abortion.

This study explores children's sex differences of emotion discrimination from facial expressions based on two dimensional model of emotion. The study group consisted of 92 children, of 40, 52, and 64 months of age, and the rate of male and female children was male children (50%) and female children (50%). Children of 92 were required to choose facial expressions related the twelve emotion terms. Facial expressions applied for experiment are used the photographs rated the degree of expression in each of the two dimensions (pleasure-displeasure dimension and arousal-sleep dimension) on a nine-point scale from 54 university students. The experimental findings appeared that the sex differences were distinctly the arousal-sleep dimension than the pleasure-displeasure dimension. In the arousal-sleep dimensionoussleepness, anger, comfort, and loneliness' emotions showed large sex differences over 1 value. Especially, while male children showed high arousal more than female children in the emotions like 'sleepiness, anger and loneliness', female children showed high arousal more than male children in 'comfort' emotion.

This study analyzes whether online political activities have an important impact on attitudes toward the legalization of same-sex marriage and the anti-discrimination law and whether these effects are different by the religion of voters. The main findings are as follows. First, the ideology variable has a significant effect on attitude toward legalizing same-sex marriage and enacting anti-discrimination law. Second, the higher the degree of online political activities, the more likely they will support two issues. Third, the effect on attitudes toward the enactment of anti-discrimination law has appeared different by religion. In other words, Protestants, compared to other religions, are more likely to oppose the enactment of anti-discrimination laws as the level of online political activities increased. Our study is meaningful in that we found online political activities play an important role in making voters' attitudes positively toward the enhancement of the right of sexual minorities. Also, although ideological conflicts are usually intense in diplomatic and security issues in Korea, the sexual minority issue would be likely to be an crucial as a dimension of ideological conflicts.

Ginkgo (Ginkgo biloba L.) is one of the most appropriate roadside trees because of a good transplantation nature and ability to grow well in urban environment. Ginkgo is a dioecious species. Sex discrimination of ginkgo is possible through comparing morphological characters of reproductive organs. However, it needs more than about twenty years for reproductive organs to appear after sexual maturity. Until now, ginkgo trees for roadside plantation have been planted without discriminating the sex because ginkgo trees have been usually planted before sexual maturity. Ginkgo nuts from the female ginkgo trees planted along the roadside emit a foul odor, and make much pollution on the streets. Thus in this study a novel SCAR marker (SCAR-GBM) for the early sex discrimination was developed. Primers were developed on the basis of the sequence of male-specific RAPD variants reported previously. False-negative problem of SCAR marker, probably caused by dominant nature, was resolved by using multiplex PCR using primers of both the SCAR-GBM and a universal primer set of atp1 region in mitochondria DNA, which resulted in improved discrimination efficiency. The results showed that DNA bands of 1,039 bp were commonly amplified by the atp1 primer set in male and female trees, and SCAR-GBM markers of 675 bp were specifically amplified only in male trees. Reproducible and specific discrimination of the multiplex PCR was finally confirmed by applying multiple male and female individuals.

We statistically analyzed the relationship between the constitution and the thickness and stiffness of skin depending on sex and age, using 1079 clinical data registered to SCIB(Sasang constitution Information Bank), and the following results are obtained : The thickness of skin has big discrimination ability in classification of Taeeumin and Soyangin, especially in women and in ages 21 or more. The stiffness of skin also has big discrimination ability in classification of Taeeumin and Soeumin, especially in Taeumin women and Soeumin man and in ages 21-60. The differences stated above have been proved to be meaningful enough by Chi-square test.
