The sexual dimorphism and intra sexual dimorphism in males of Rhinogobius brunneus were investigated at Jiam stream, a tributary of the Bukhan river from May, 2005. The frequency distributions in standard length were similar for the females and maleLs, but maleSs were smaller than the females and maleLs. The ratio of MaleL (N=79) to males (N=79) was 1 : 0.46. The comparison between female (N=79) and maleL (N=79) gave significant differences (P<0.05) in 18 morphometric characteristics (SNL, AHD, PHD, ML, DL, MW, AHW, IFW, PHW, ED, HL, FDFL, SDFB, CFL, AFB, VFL, PFL, PFB) and 12 characteristics (SNL, AHD, ML, DL, MW, AHW, IFW, PHW, HL, FDFI, CFL, PFB) (P<0.001). Eight morphometric characteristics (SNL, ML, DL, MW, HL, CFL, VFL, PFL) in female (N=36) and males (N=36) had significant differences (P<0.05) and three characteristics (ML, DL, HL) had very significant differences (P<0.001). Eleven characteristics (SNL, AHD, PHD, ML, DL, MW, AHW, IFW, PHW, HL, FDFL) were significantly different in maleL (N=36) and males (N=36) (P<0.05) and six (ML, DL, MW, AHW, HL, FDFL) were very significantly different (P<0.001).

The purpose of this study was to examine the awareness of dental hygiene students on sexual harrassment in an effort to provide some information on the prevention of sexual harrassment. The subjects in this study were 738 dental hygiene students at colleges located in four different large regions. As for the concept of sexual harrassment, the students got 4.33 out of a possible five in that regard, which was a high score. But they got a relatively lower score of 3.42 in awareness of the causes of sexual harrassment. They got the highest score of 4.42 in physical sexual harrassment among different types of sexual harrassment. Regarding the offender of sexual harrassment, they got 2.81 out of a possible five, which was lowest among their scores in the items of sexual harrassment awareness. There were statistically significant differences in sexual harrassment awareness according to gender, age, grade and religion. The above-mentioned findings of the study illustrated that the dental hygiene students were well aware of sexual harrassment in general, but that the way they coped with it was quite passive. The development of educational programs on how to prevent sexual harrassment and cope with it is required to spread better awareness of sexual harrassment among college students and to encourage them to properly cope with it.

The purpose of this study was to examine whether the gender, grade and school type of middle school students made any differences to their sexual awareness and sexual behaviors in an effort to lay the groundwork for providing more efficient sex education. The research questions were posed as follows: First, what is the sexual awareness of middle school students? Second, what are the sexual behaviors of middle school students? Third, are their gender, school year and school type related to their sexual awareness and behaviors? The subjects in this study were 976 middle school students from Gyeonggi province. After a survey was conducted with questionnaires prepared by this researcher based on earlier studies to suit the purpose of the study, the collected data were analyzed with SPSS 10.0 program. The frequency analysis, x2 test and correlational analysis were implemented, and basic statistical data were obtained. The conclusions were as follows: First, regarding their sexual awareness, the largest group of them agreed that one must report in case of being raped(4.36), and the smallest number of them thought that one might have a sexual relationship with a person other than his or her spouse after marriage(1.56). Second, as for experience of indecent materials, part of sexual behaviors, 67.4 percent had ever contacted such materials. The most common medium through which they contacted them was the Internet(56.5%). The above-mentioned findings suggested that the sexual awareness of the middle school students wasn't influenced by gender or school type. But that varied with grade, as the third graders had the best sexual consciousness. Their sexual behaviors were different according to gender. The boy students contacted more indecent materials, and their experience of such materials varied with grade, since the third graders contacted the most obscene materials. And that also varied with school type, and the non-engineering students contacted more obscene materials. As for sexual drives, their masturbation experience was different according to gender, grade and school type. The number of the boys who practiced masturbation was four-fold larger than that of the girls, and the second graders had more such experience. By school type, the non-engineering students practiced more masturbation, but there was no significant gap between their kissing, caressing and dating experiences.

This study attempted to analyze human brain responses toward visual content through EEG signals and intended to measure brain wave reactions of different age groups to determine the sexuality level of the media. The experimental stimuli consist of three different video footage (rated ages 12, 15, and 18) to analyze how subjects react in situations where they actually watch sexual content. For measuring and analyzing brain wave reactions, EEG equipment records alpha, beta, and gamma wave responses of the subjects' left and right frontal lobes, temporal lobes, and occipital lobes. The subjects of this study were 28 total and they are divided into two groups. The experiment configures a sexual content classification scale with age or gender as a discriminating variable and brain region-specific response frequencies (left/right, frontal/temporal/occipital, alpha/beta/gamma waves) as independent variables. The experimental results showed the possibility of distinguishing gender and age differences. The apparent differences in brain wave response areas and bands among high school girls, high school boys, and college students are found. Using these brain wave response data, this study explored the potential of developing algorithm for measurement of age-specific responses to sexual content and apply it as a film rating.

Purpose: The purpose of this study was to investigate differences of subjective, objective knowledge and educational need about contraceptives according to sex in college students. Methods: Data were collected by a self-administered questionnaire from 84 male and 111 female college students on May, 2008. PASW 18.0 program was used for data analysis. Results: There were significant differences in age, major, grade, place of residence, and experience of sexual intercourse between male and female college students. There was a significant difference in objective knowledge about contraceptives between the two groups, but no significant difference in subjective knowledge. The positive correlation was shown between subjective and objective knowledge about contraceptives. Even when demographic variables such as age, major, grade, place of residence, and experience of sexual intercourse were controlled, sex was a significant influencing factor on subjective and objective knowledge about contraceptives. Educational need about emergency contraceptive pills was significantly different and ranking of educational need about contraceptives was also different between the two groups. Conclusion: These results suggest that different education programs according to sex are needed to maximize the effect of contraceptive education and sexual characteristics are considered to give an education to college students.

A study was performed to investigate the degree of similarities and differences in components of craniofacial complex between Korean twins and normal children by lateral cephalometric analysis. Dimensions of S-N, S-Ba, N-Ba, Go-Me, Ar-Go and Ar-Me were against linear measurement and angles of N-S-Ba and gonial against measurement in twins and control groups. The lateral cephalograms of twin were composed of 88 twins aged from 7 to 12:44 males aged 10.65 and 44 females aged 9.55, while those of 50 normalities were composed of 25 males and 25 females aged 10.9 respectively. In order to analyze growth proportion and sexual differences, twins were divided into 3 groups according to two year age intervals and the author compared male with female in 3 groups. For the purpose of observing similarities and differences in twins and normalities by sex, total twins were compared with normalities. The obtained results were as follows: 1. There was no difference in craniofacial complex between plotted angular normalities. 2. In general, the measurements of male were larger than both twins and normalities, but there were no statistical sexual differences in both groups. 3. The growth proportion of mandible by aging was larger than that of face twins and those of female significances of in twins. 4. The growth pattern of gonial angle showed slightly reducing tendency in twins by aging. 5. There was little difference in the growth proportion of both male and female.
