The estimation of recurrence interval for fault activity and earthquake is an important input parameter for seismic hazard assessment. In this study, the methods of recurrences interval estimation were reviewed and tentative calculation was performed for age dating data which have uncertainty. Age dating data come from previous studies of Ulsan fault system which is a well developed lineament in the southeastern part of korean Peninsula. Age dating for fault gouges, parent rocks, Quaternary sediments and veins were carried out by several researchers through various methods. Recurrence interval for fault activity was estimated on the basis of the age dating data of minor fault gouge and sediments during past 3Ma. The estimated recurrence interval was about 430-500 ka. Exact estimation of recurrence interval for fault activity need to compile more geological data and fault characteristics such as fault length, amount of displacement, slip rate and accurate fault movement age. In the future, the methods and results of fault recurrence interval estimation should be considered for establishing the criteria for domestic active fault definition.

Based on Yonsei Evolutionary Population Synthesis (YEPS), we have investigated the effect of horizontal branch stars (HBs) on the age-dating of simple stellar populations (SSPs). A detailed comparison of YEPS SSP with H_beta of M31 globular clusters (GCs) reveals (1) that the age dating without HB prescription gives ~5 Gyr younger ages for metal-poor M31 GCs, and (2) the age dating with HB prescription does not need any age gap between metal-poor and metal-rich GCs. This result is parallel to the well-known discrepancy in ages derived from integrated Balmer strengths and isochrone fittings of Milky Way GCs (MWGCs). Without a synthetic blue HB model, we cannot explain strong Balmer indices of metal-poor and old MWGCs. Our results suggest that the SSP model with well calibrated HBs should be used for the age-dating of SSPs to avoid a serious underestimation of ages due to the strong Balmer indices.

This study investigated differences of opinion between youth and their parents about having permission to date. Opinions on youth dating permission was gathered from 150 adolescents and their parents. The results were as follows: first, for adolescents there were significant differences of opinion about youth dating permission depending on gender, age, scholastic record, and birth order, but for parents, the difference related to the gender and age of adolescents. Second, the result indicated that adolescents had a greater acceptance of dating permission than their parents, expressing a generational difference. Third, where the scholastic record of subjects was low, where subjects were non-eldest siblings, and where the parents' level of youth dating permission was high, the level of youth dating permission was higher. A main predictor of youth's level of dating permission was the level of the parents about youth dating.

This study investigates the factors associated with adolescent females' sexual behavior. Results from 390 adolescent females reveal that dating atmosphere was the strongest and the most influential risk factor predicting adolescent females sexual behavior, which has been a neglected variable in the research of adolescent sexual behavior. Age and similarity of sexual attitude with her dating partner, in addition to the dating experience had very significant impacts on highly sexually experienced adolescent females' sexual behavior. Adolescent females with low sexual experiences were significantly affected by similarity of sexual attitude with dating partner, siblings, and peers, her own attitude, age, and dating atmosphere. The findings from this study also indicate that parental supervision, dating atmosphere, respondent's sexual attitude, love for partner, and communication with parents on sexual issues were significant factors for determining adolescent females' sexual involvement.

The purpose of this study is to explore gender differences in elderly's dating experience and related variables. 427 elderly of age 65 or older participated. The results are as follows. 1. 80% of widowed elderly had no dating experience, and far more elderly men than women had dating experience. 2. Attitudes towards dating, of both elderly themselves and their children, had influence on the elderly's dating experience, regardless of gender. This indicates that the elderly's own acceptance and their children's positive attitude are important to the elderly's dating experience. 3. Gender differences were found in influences of living arrangement (whether they lived with their children or not), economical reasons, and personality factors. These variables proved significant only for the elderly men. More elderly men who did not live with their children than the elderly men who did had experienced dating, and economical reasons along with personality factors proved to be obstructive for elderly men's dating life.

Objectives: The aim of this study was to explore perceived meanings of dating and marriage among well-educated Korean couples who were in optimal marriageable ages. Particularly, an emphasis was placed on finding out where the traditional gender norms and post-modern contexts intersect on the couples' course of dating and marriage. Method: We undertook a qualitative analysis of 8 couples (age: 26-34) dating. Participants were limited to university graduates of upper-middle rank universities in Seoul, South Korea. The rationale for choosing such sample was based on the idea that characteristics of class is inherent in the act of dating and marriage, and that such characteristics lead to different contextual experiences in dating and marriage. This study was based on interviews conducted over a three-month time span. The interviews were first transcribed into research text and then subjects and key categories were drawn from the transcripts for analysis. Results: Participants sought meanings of joy, learning, and self-improvement in dating, and they were free from traditional gender norms in their romantic relationships. They viewed marriage as having a permanent companionship with their partner, becoming independent from their parents, and/or a social norm to be followed. Participants reported mixed perceptions about marriage in such fashion that they described their parents' relationship in terms of a gendered leader-supporter relationship, while viewing their own relationship as being genderless partners. In transition to parenthood, however, they regressed to traditional gender norms dichotomized as women being a homemaker and men being a breadwinner. In sum, participants displayed expectations that were inconsistent with regard to dating and marriage over the study period. That is, during the course of dating and early marriage, they did not hold separated gender norms; however, when transitioning from being a newly married couple to giving their first childbirth, expectations shifted to traditional gender norms and values. Conclusion: This suggests that it is not marriage, but the experience of childbirth and motherhood, which strengthen traditional gendered norms, engendering regeneration of the gender norms in families. The results indicate that there is a need to promote co-parenting behavior among the newly-married couples and to educate gender equality about parent roles or for parents in South Korea so that they can overcome traditional gendered norms in family.

Objectives: This study is a descriptive research study conducted to grasp the Prediction factors of the sexual violence experience of college students. Methods: A convenience sampling was performed for 500 students from one college located in Gyeongsangbuk-do, who agreed to the purpose of this study. Data collection was conducted from October 5, 2015, to October 23, 2015, by filling out the self-report questionnaire. Among the 450 subjects excluding those with missing values, a questionnaire of dating violence experience was applied to 317 college students who answered that they had a friend of the opposite sex, and variables and prediction factors related to dating violence experiences were identified. The statistical methods used were descriptive statistics, x²-test, t-test, Pearson's correlation coefficient and binary logistic regression analysis. Results: As a result of the study, the experience of sexual behavior before entering college (𝑥²=6.52, p=.011), experience of sexual violence damage before entering college(p=.045), the experience of sexual assault before entering college (p=.007) and experience of school violence damage(p=.002) were variables related to the sexual violence experience of college students. School violence victimization (OR=4.831, p=.007) and controlling dating partners (OR=1.349, p<.001) were predictors of dating sexual violence. Dating sexual violence experience group were compared to dating sexual violence non-experience group, the relative degree of controlling dating partners was high (t=4.25, p<.001) and had a traditional gender role attitude (t=2.94, p=.004). and there was a positive correlation (r=.358, p<.001) between controlling dating partners and gender role attitude. Conclusions: In order to prevent sexual violence on dating among college students, it is expected that more effective health education results will emerge if the contents of the school-age school violence victimization experience and the control of dating partners, which are predicted factors of sexual violence on dating, are included in the sexual violence prevention program.
