This study focused on comparing the following acoustic changes according to age and sex in adulthood: Fo, Jitter, Shimmer, and NHR. One hundred twenty Korean adults were divided into three age groups (20's, 50's, and 70's) and two sex groups (male and female). The subjects of this study performed three tasks: (1) sustained three vowels; (2) read on paragraph of 'Taking a Walk' (3) explained a picture. The data was analyzed using the MDVP of Multi-Speech. In the parameter of Fo, sex and age were influential factors. In the parameters of Jitter, Shimmer and NHR, the effect of sex and age was different in all three parameters. When the groups organized by sex were analyzed by age, the 20's group showed a statistical difference in all four parameters (Fo, Jitter, Shimmer, and NKR), when compared to the other two age ranges of 50's and 70's. We need to consider our standard parameter for the normal voice in the Korean elderly because the 50's and 70's age normal groups in our study are out of the current range of normal in MDVP.

This study investigates the perception of price and the propensity to conspicuous consumption in the purchase of clothing among college students and the relation between the perception of price and the propensity to conspicuous consumption. The data for this study were collected from 1,015 Korean college students. In order to analyze the data, statistical methods such as frequency, percentage, mean, standard deviation, factor analysis, ANOVA, scheffe-test, Pearson's correlation, and Cronbach's a were used with the SPSS statistical package program. The major study findings were as follows. 1. The perception of clothing price among college students was classified into five factors: high price-oriented, discount-oriented, high quality-price rate-oriented, low price-oriented, and effectiveness-oriented. 2. The propensity to conspicuous consumption of clothing among college students was classified into four factors: brand name conspicuousness, conspicuous pursuit of vogue, symbol of their social position, and imported goods conspicuousness. 3. High price-oriented and discount-oriented were different significantly according to sex, age, father's educational level, monthly income, monthly allowance amount. High quality-price rate-oriented and low price-oriented were different significantly according to sex, father's educational level, monthly income, monthly allowance amount. Effectiveness-oriented was different significantly according to sex, age. 4. Brand name conspicuousness, conspicuous pursuit of vogue and imported goods conspicuousness were different significantly according to sex, age, father's educational level, monthly income, monthly allowance amount. Symbol of their social position was different significantly according to sex, age, father's educational level, monthly income. 5. High price-oriented, discount-oriented and high quality-price rate-oriented have the highly positive correlation with four factor of propensity to conspicuous consumption of clothing. Low price-oriented has the negative correlation with four factor of propensity to conspicuous consumption of clothing. Effectiveness-oriented has the lowly positive correlation with four factor of propensity to conspicuous consumption of clothing.

Sleep is an essential physiological process, especially for proper brain function through the formation of new pathways and processing information and cognition. Therefore, when sleep is insufficient, this can result in pathophysiologic conditions. Sleep deficiency is a risk factor for various conditions, including dementia, diabetes, and obesity. Recent studies have shown that there are differences in the prevalence of sleep disorders between genders. Insomnia, the most common type of sleep disorder, has been reported to have a higher incidence in females than in males. However, sex/gender differences in other sleep disorder subtypes are not thoroughly understood. Currently, increasing evidence suggests that gender issues should be considered important when prescribing medicine. Therefore, an investigation of the gender-dependent differences in sleep disorders is required. In this review, we first describe sex/gender differences not only in the prevalence of sleep disorders by category but in the efficacy of sleep medications. In addition, we summarize sex/gender differences in the impact of sleep disorders on incident dementia. This may help understand gender-dependent pathogenesis of sleep disorders and develop therapeutic strategies in men and women.

This research was conducted at Langgur City, Southeast Maluku Regency, Maluku Province, Eastern Indonesia from November 2020 to February 2021 to study biological aspects of roundscads (Decapterus spp.) which consist of species composition, sex ratio, gonad maturation level, size distribution, length-weight relationship and condition factor. Samples were collected at traditional fish market in Langgur City. Fish samples collected at the market were put into cool box and then brought to the laboratory for further examination. Fish samples were identified, separated based on species, dissected to determine their sex and gonad maturation stage and then measured. Totally, there were 290 specimen collected which consist of five species namely Decapterus kurroides, D. macarellus, D. macrosoma, D. muroadsi and D. russelli. Sex ratio between male and female for all species showed 1:1. Gonad maturation level showed that stage I and II have higher percentage than stage III and IV indicates immature fish more dominant compare to mature one. Among five species found, D. macarellus has larger size while the smaller belongs to D. muroadsi. Results of length-weight relationship analysis showed that roundscads inhabiting Southeast Maluku waters have isometric and negative allometric growth pattern with relative condition factor around 1.00.

The purpose of this study was to examine the differences in men's thinking and attitude on prostitution and gender based on the previous experience of buying sex. It was an exploratory survey for planning future studies and movements for changing a way of thinking in relation to prostitution. A total of 1328 male adults(above 19 years) completed a questionnaire consisting of general thinking of buying sex, tolerance limit of sexual behavior, and sex role egalitarianism. The respondents answered differently in the probability of paying for sex in future and the way how to get a sex information according to the previous experience of buying sex. Those respondents who had paid for sex, had higher scores on three types of sex attitude measures than those who did not. The previous experience of buying sex was significantly correlated with sub-factors of buying sex, tolerance limit of sexual behavior, and sex role egalitarianism except for the sub-factor on recognizing a sex worker as a victim (factor 4 of buying sex). These results suggest that men who had paid for sex had more traditional gender-stereotypes and attitudes. Implications and limitations of this study were discussed in a feminist perspective.

The 46,XX testicular disorder of sex development (DSD) is a rare condition in which 46,XX individuals develop testicular differentiation and virilization. Translocation of the sex-determining region Y (SRY) onto the X chromosome is the main cause of 46,XX testicular DSD, whereas dysregulation between pro-testis and pro-ovarian genes can induce SRY-negative 46,XX testicular DSD. Nuclear receptor subfamily 5 group A member 1 (NR5A1), a nuclear receptor transcription factor, plays an essential role in gonadal development in XY and XX embryos. Herein, we report the first Korean case of SRY-negative 46,XX testicular DSD with a heterozygous NR5A1 p.Arg92Trp variant. The patient presented with a small penis, bifid scrotum, and bilateral undescended testes. Whole exome sequencing revealed a heterozygous missense variant (c.274C>T) of NR5A1. Our case highlights that NR5A1 gene variants need to be considered important causative factors of SRY-negative non-syndromic 46,XX testicular DSD.

Despite the fact that the national family planning program in korea has accomplished its primary goals of fertility reduction and universal contraceptive use, the induced abortion is still high and there has been an increasing trend in the population sex ratio at birth. It seems that the changes in the imbalance of sex ratio have originated from traditonal boy preference. This indicates that much of the current family planning program can be overhauled, so that the program quality could be better controlled, by preventing the number of unwanted pregnancies and the imbalance of sex ratios. This paper aims, therefore, to examine the determinants of induced abortion through the investigation of pregnancy outcomes and their changes over time and to study the interaction between induced abortion, boy preference and the imbalance of sex ratio in Korea. The abortion rate had increased rapidly until the mid-1980s when there were about the same number of abortions as live births. Thereafter, the abortion rate has been maintained at this high level. By parity it shows a much higher abortion rate for a higher parity at all time. From the first parity, the sex composition of previous children stands out as the most important factor in deciding the pregnancy outcome at all time. The probability of a pregnancy ending in an abortion increases substantially when parents already had a son. The decline of the desired family size and the sustained strong son preference has made the sex of children a more important factor in the determination of the pregnancy outcome. Women's education has had consistently positive effects on the probability of a pregnancy ending in an abortion, but the effect shows a steady decline over time. The premarital pregnancy and urban residence also increase the abortion probability. This study suggests that the main concerns of the family planning program should be to strengthen the social support policies so as to weaken the son preference value leading to a balanced sex ratio and prevention of induced abortions.
