The extraction of third molars is a common task carried out at dental/surgery clinics. Postoperative pain is one of the two most common complications of this surgery, along with dry socket. Knowledge of the frequent risk factors of this complication is useful in determining high-risk patients, planning treatment, and preparing the patients mentally. Since the risk factors for postoperative pain have never been summarized before while the risk factors for dry socket have been highly debated, this report summarizes the literature regarding the common predictors of postextraction pain. Except for surgical difficulty and the surgeon's experience, the influences of other risk factors (age, gender and oral contraceptive use) were rather inconclusive. The case of a female gender or oral contraceptive effect might mainly be associated with estrogen levels (when it comes to dry socket), which can differ considerably from case to case. Improvement in and unification of statistical and diagnostic methods seem necessary. In addition, each risk factor was actually a combination of various independent variables, which should instead be targeted in more comprehensive studies.

The purpose of this study was to exam the effects of gender-role identity on adolescents' self esteem, clothing behaviors and favorite clothing image, focusing on analysis by adolescent' sex and age variable. The research method was survey and the subjects were 447 male and female adolescents in Daejeon, Korea. The questionnaire consisted of 4 measurement instruments (gender-role identity, self-esteem, clothing behaviors, and favorite clothing image) and subject' demographic attributions. The data were analyzed by factor analysis, $X^2$ test, t-test, ANOVA(analysis of variance), Duncan's multiple range test, and Pearson's correlation analysis, using SPSS program. The results are as follows. First, adolescents' gender-role identity and self- esteem were different by age rather than sex. Middle school students were represented by undifferentiated type while high school students were represented by androgynous type, and high school students had higher self-esteem than middle school students. Second, four factors emerged on clothing behaviors(clothing interest & psychological dependence, ostentation, conformity, and comfort), and favorite clothing image(characteristic, neat, active, and romantic image). Third, gender-role identity had important effects on self esteem; androgynous type had higher self esteem than other gender-role identity type. Forth, self-esteem had significant relationship with clothing behaviors and favorite clothing image, and these relationships were different by adolescent' sex and age variable. Fifth, gender-role identity had important effects on clothing behaviors; and rogynous type had more clothing interest, ostentation and comfort than any other gender-role identity type. Sixth, gender-role identity had important effects on favorite clothing images; androgynous type pursued more various clothing images than any other gender-role identity type.

Objective: The purpose of this study was to investigate the relationships among mothers' play beliefs, children's gender and home play frequency, and their preferences for three types of play. Methods: Totally 256 mothers of 5-year-olds participated in the survey in metropolitan area. Data were analyzed with t-test, Pearson's correlations, and stepwise multi-regression using SPSS 22.0. Results: First, boys and girls showed little difference in their home play experiences. Boys preferred active and rough play, while girls preferred quiet play. Second, mothers' play beliefs and children's home play frequency had partial correlations with children's play preferences. Third, predictors of children's play preferences were influenced by the types of play. Children's gender and mothers' play beliefs affected children's preference for active play. Only gender explained children's preference for rough play. Finally, children's gender, home play frequency, and mothers' play beliefs influence children's preference for quiet play. Conclusion: In conclusion, gender is an important factor of children's play preferences, and mothers' play beliefs and children's home play frequency affect their preferences for a specific type of play.

There's an opinion that it may be a combination of change of values and social economic factors that caused low fertility of Korean society. This study intends to analyze actual conditions of family children values and gender role centered on university students in a marriageable age so draw a policy implication for overcoming low fertility. Main findings of this study are like following. First, as for analysis of childbirth intention shows average score of $3.35{\pm}1.142$ presented sex distinction that men have a higher tendency to women. Second, in gender role attitudes, it shows that gender role related on women's social activities($2.06{\pm}0.739$), traditional gender role in family($2.41{\pm}0.789$) influence on childbirth intention (p<0.001). Third, in family children values indicates moderate scores($2.95{\pm}0.648$) that son's position in family ($2.33{\pm}0.911$), relation between children and parents($2.80{\pm}1.050$), individual's position in family($3.56{\pm}0.671$) influence on childbirth intention(p<0.000) in the traditional values. Measures against low fertility will prove effective when family values are established favorable to marriage, childbirth, rearing, gender equality is settled in a society as a whole and related systems.

Objectives Standardization of head size is essential for the volume study. Cortical thickness analyses are increasingly being used in many fields of neuroscience. However, it is not established whether head size correction should be done for thickness study. Methods Using the Open Access Series of Imaging Studies data, we determined cortical thickness of 316 cognitively normal participants aged 18-94 with FreeSurfer. The association between head size and cortical thickness of whole cortical mantle and in each lobe among age tertile groups was assessed. Estimated total intracranial volume (eTIV) was calculated for determining head size. Results Across all participants, cortical thickness in whole brain except some areas in cingulate and insula decreased with aging. eTIV had positive correlation with the thickness of frontal, parietal, occipital and whole brain areas. However, the age effect was not shown in whole brain of the first tertile group and in cingulate areas of the third tertile group. eTIV had negative correlation with the thickness of cingulate in the third tertile group. Gender effects were shown in some areas in third tertile group, but it would be due to difference of head size. Conclusions These findings suggest that head size standardization might be done especially in older population and in studies of paralimbic areas.

Purpose: This study investigated the developmental stages of third molars in relation to chronological age and compared third molar development according to location and gender. Materials and Methods: A retrospective analysis of panoramic radiographs of 2490 patients aged between 6 and 24 years was conducted, and the developmental stages of the third molars were evaluated using the modified Demirjian's classification. The mean age, standard deviation, minimal and maximal age, and percentile distributions were recorded for each stage of development. A Mann-Whitney U test was performed to test the developmental differences in the third molars between the maxillary and mandibular arches and between genders. A linear regression analysis was used for assessing the correlation between the third molar development and chronological age. Results: The developmental stages of the third molars were more advanced in the maxillary arch than the mandibular arch. Males reached the developmental stages earlier than females. The average age of the initial mineralization of the third molars was 8.57 years, and the average age at apex closure was 21.96 years. The mean age of crown completion was 14.52 and 15.04 years for the maxillary and the mandibular third molars, respectively. Conclusion: The developmental stages of the third molars clearly showed a strong correlation with age. The third molars developed earlier in the upper arch than the lower arch; further, they developed earlier in males than in females.
