Purpose: To develop a tool to evaluate middle school sex education programs. Method: An evaluation tool was developed in 4 stages: first, preliminary items were developed based on the sex education guidebook for teachers published by the Korean Ministry of Education and Human Resources Development; second, a panel of specialists reduced the number of preliminary items by 3 validity tests on the contents; third, final items were selected from the results of pre-test. Finally, reliability and validity were tested by a sample of 601 middle school students of both genders attending all three grades. Result: The developed evaluation tool contained 31 items on the sexual knowledge and 22 items on the sexual attitude. The results of reliability tests were as follows: Cronbachs alpha for sexual knowledge was .84; and for sexual attitude was .88. Conclusion: This study suggested the developed evaluation tool for sex education programs for middle school students had a high degree of reliability and validity. Therefore, it can be utilized to effectively evaluate Korean middle school sex education programs.

This study investigated the relation of androgynous parent's child-rearing practices to children's self-perceived competence by comparison of the effectiveness of androgynous people as parents compared with parents who are other-typed in their sex-role identity. The subjects were 362 third and sixth grade children and their parents selected from two elementary schools in Seoul. The instruments were a children's self-perceived competence scale, a perception of maternal warmth and control scale, a perception of paternal warmth and control scale, parent's self-esteem scale, and parent's sex-role identity scale. Frequencies, percentiles, mean, ${\chi}^2$ test, two way-ANOVA, one way-ANOVA, Cronbach's ${\alpha}$ and $Scheff{\acute{e}}$-test were used for data-analysis. The major findings showed that (1) Androgynous and masculine fathers had higher self-esteem than feminine or undifferentiated fathers. Androgynous, masculine, and feminine mothers had higher self-esteem than undifferentiated mothers. (2) There was no difference in children's perception of parental warmth and control as related to parent's sex-role identity. Androgynyous parents were not more likely to be authoritative parents. (3) Sons of androgynous parents had higher self-perceived competence than those of sex-typed parents, while daughters of sex-typed parents had higher self-perceived competence than those of androgynous parents.

Objectives: The aim of this retrospective study was to investigate factors associated with increased difficulty in the surgical extraction of impacted lower third molars and to improve identification of difficult cases. Materials and Methods: A total of 680 patients who required 762 surgical extractions of impacted lower third molars from 2009 to 2014 were enrolled in the study. Demographic factors, clinical factors, radiographic factors, surgical extraction difficulty, and presumed causes of difficulty were collected. Data were statistically analyzed using IBM SPSS Statistics version 23. Results: Age, sex, depth of impaction, and blurred radiographic image influenced difficulty in surgical extraction. The position of the impacted tooth influenced surgical difficulty, especially when it was accompanied by other factors. Conclusion: It is challenging to design a reliable and practical instrument to predict difficulty in surgical extraction of impacted lower third molars. To identify very difficult cases, root investigation using computed tomography is advised when impacted tooth position suggests difficult extraction.

Purpose: This study was conducted to identify the influences of the attitudes of pregnant women and their husbands towards sex during pregnancy on sexual function. Additional purpose was to compare the frequency of sexual dysfunction according to gender and gestational trimester and to describe the changes in sexual behavior according to the gestational trimester. Methods: In this study, 231 pregnant couples completed self-report questionnaires during their visits to women's hospitals or community health centers. The questionnaires assessed general characteristics, maternal/paternal sexual attitudes towards sex during pregnancy (Maternal Sex during Pregnancy Scale, MSP/Paternal Sex during Pregnancy Scale, PSP), and sexual function (using the Female Sexual Function Index and International Index of Erectile Function, respectively). Multiple regression analysis was done to test the research model using SPSS version 23.0. Results: In this study, 74.9% of pregnant women and 38.5% of their husbands reported sexual dysfunction. Sexual dysfunction was prevalent in pregnant women in the first trimester and prevalent in husbands in the third trimester. MSP (β=.44, p<.001) in pregnant women and PSP (β=.39, p<.001) and being in the first trimester (β=.17, p=.012) in husbands influenced sexual function during pregnancy. In the first trimester, the scores for attitudes towards sex during pregnancy were the lowest in pregnant women, while they were the highest in their husbands. Conclusion: Positive attitudes about sex during pregnancy are important for sexual function in pregnant couples. Because the difference in attitudes towards sex during pregnancy between pregnant women and their husbands was greatest in the first trimester, sexual health interventions need to be provided in early pregnancy.

The purpose of this study was to examine the effect of socioeconomic status and the children's sex on mothers'teaching strategies and their children's responses during a cooperative problem-solving task. The subjects were 15 higher SES mothers and their 5-years-old children dyads. The mothers' teaching strategies and their children's responses were videotaped during a cooperative problem solving task and analyze using a scheme developed by Kermani and Brenner. The results of this study were as follows. First, the mothers with higher SES were more likely to promote 'independence' and less likely to 'verbal prompt'direct performance' than the mothers with lower SES. Second, the children from higher SES families were more likely to refuse their mothers' assistance. Third, the mothers of boys were more likely to use the 'direct teaching'and 'modify'strategies and less likely to use 'independence promoting'strategy than the mothers of girls. Finally, girls were more likely than boys to ask questions for assistance or assurance.

Objectives. The purpose of this study was to evaluate mandibular third molars as risk factors for angle fracture in a patient sample with fractured mandible. Materials and methods. The medical records and panoramic radiographs of 107 patients with mandibular fractures were examined. The presence and absence and degree of impaction of the lower third molar were assessed for each patient and related to the occurrence of fracture of the mandibular angle. Data were also collected for age, sex and mechanism of injury. Data were analyzed by a chisquare statistics and Student t test. Result. The incidence of mandibular angle fracture was found to be significantly greater when a lower third molar was present(p <0.05) especially at class III state.(p < 0.05)(by Pell & Gregory system) Of the 78 patients with a lower third molar, 46(58.97%) had angle fractures. Of the 29 without a lower third molar, 24(82.76%) had not angle fractures. Conclusion. The result of this study showed that the mandibular angle that have a lower third molar is more susceptible to fracture when exposed to an impact than an angle without an lower third molar.
