This study is to investigate the effect of pre-primary teachers' gender and earth science completion while attending high school on the diversity of concepts, the level of conceptual understanding, and misconceptions about seasonal changes. This study was conducted with 71 pre-primary teachers. The conclusion of this study is as follows. First, the area of concepts used by pre-primary teachers to explain seasonal changes showed a greater difference depending on whether or not they completed earth science while attending high school, rather than depending on gender. Second, although there was no significant gender difference in the conceptual level of pre-primary teachers for seasonal change, the group who completed earth science while attending high school had a statistically significantly higher level of conceptual understanding than the group that did not complete it. Third, the ratio of misconceptions related to seasonal change of pre-primary teachers by gender was not significant, but the group who did not complete earth science while attending high school had a statistically significantly higher percentage of misconceptions than the group that completed it. As a result of the above examination, it is judged that the area of concepts, the level of conceptual understanding, and the misconceptions about seasonal changes of pre-primary teachers are more affected by the completion of earth science courses during high school than by gender differences.

The purposes of this study were to compare the disability prevalence and its related factors between men and women. The data used for the analysis was the National Health and Nutrition Survey, 2005, and the instrument of measuring disability was the K-ADL which had been developed by Won(2002). Chi-square test and multivariate logistic regression were used to test the gender difference. In the bivariate analyses, women had more disabilities than men among the entire elderly and the young elderly. However, there was not gender difference of disability among the old elderly. After controlling for age and other factors related to disability, no gender differences in the prevalence of disability were found. However, in the same analyses for the individual activities of daily living, men had more disabilities than women for all the activities except bathing and incontinence control. In conclusion, women's higher prevalence of disability in the univariate and bivariate analyses were spurious, because it was disappeared when other related factors to disability were controled for and women's disability became lower than men for some activities of daily living.

In this study, total astigmatism and corneal astigmatism were studied 328 eyes of healthy Korean for astigmatism. Total astigmatism was measured by fogging-and-dial technique, and corneal astigmatism was measured with Topcon OM-4 keratometer. Residual astigmatism was determined by a discrepancy between total and corneal astigmatism. The results were as follows: As they aged, there were a statistically significant changes in total and corneal astigmatism but not in residual astigmatism. And the amount of with-the-rule total and corneal astigmatism had a tendency to decrease, but residual astigmatism had no changes. From 30 years, total astigmatism showed a tendency to become against the rule. The average diopteric value was +0.342D in total astigmatism. +0.920D in corneal astigmatism and -0.579D in residual astigmatism.

The purpose of this study was to analyze the nerve damage after tooth extraction and implant surgery, and to establish a predictive model for assessment and management of dysesthesia. In this questionnaire study, the subjects chosen for this study were 276 dentists who answered the questionnaire about dysesthesia after tooth extraction and implant surgery. The analysis of the results consist of the sex and age distribution, affected site, associated symptoms, rate and duration of the recovery. The results are summarized as follows. : 1. There were no significant difference between the sex and the dysesthesia. 2. The most common affected site was the mandibular region. In the group of the implant surgery, 100% affected the mandibular site. The tooth extraction group was 93.2% affected. 3. Pain was one of the most associated symptom with dysesthesia-46.5% of the tooth extraction and 44.8% of the implant surgery. 4. The recovery ratio was 72.3% in the tooth extraction, 71.8% in the implant surgery. Most of them, they recovered in $1{\sim}6$ months. In conclusion, most of dysesthesia may be recovered within 1 year. However, the possibility of persistent dysesthesia should not be neglected. Therefore, practitioners must discuss the possibility of nerve injury with their patients, and include this possibility in the consent forms. Various methods of monitoring recovery of sensation should be considered for objective assessment of prognosis. In addition, immediate referral to orofacial pain specialists can offer the patients an opportunity for more effective and noninvasive treatments.

This study is based on the data of adults between ages of 19~65 yrs of the National Health and Nutrition Survey 4th in year of 2009, which includes symptoms of temporomandibular disorder within gender and age. Subjects included in this study were 2,738 males and 3,427 females, total of 6,165. All statistical analysis was measured by Window SPSS 17.0K Program (SPSS Inc., Chicago, USA). Prevalence of analysis of gender, age, and symptoms of temporomandibular disorder was measured by descriptive statistics, and in order to find relationship among gender, age, and symptoms of temporomandibular disorder was based on crosstabulation analysis. As results, prevalence of TMJ sound was 10.1%, of TMJ pain was 1.5%, and of TMJ limitation was 2.0%. Among the three symptoms of temporomandibular disorder, subjects who have at least one symptom was 1.2%. Prevalence of TMJ sound, of TMJ pain, and of TMJ limitation in female were 10.7%, 1.8% and 2.2%, respectively, which were greater than in male 9.3%, 1.2% and 1.6% respectively but it was stastically insignificant (p>0.05). Prevalence of TMJ sound, of TMJ pain, and of TMJ limitation in ages between 19~24 yrs were 18.7%, 3.4% and 4.2% respectively, which were higher than any other ages (p<0.05). Also prevalence of having at least one symptom of temporomandibular disorder, at least two, and three all were higher in females but stastically insignificant (p>0.05). On the other hand, prevalence of having at least one symptom of temporomandibular disorder, at least two, and three all were greater in age below 45 yrs and was stastically significant (p<0.05).

The purpose of this study was to assess the association between habitual snoring and metabolic syndrome in the Korean population and to evaluate it's possible gender variations. The study subjects were 2,007 volunteers aged 40-69 years who participated in regular health check-ups(male:434, female:1,573) from May 2012 to December 2012. Standard interviews, anthropometrics and biochemical studies were conducted. Habitual snoring was defined as snoring more than 4 days per week. The prevalence of metabolic syndrome in our sampling pool was 17.4% (male: 20.7%, female: 16.5%), and this increased with age. After adjusting for age, smoke and alcohol consumption, sleep duration, regular exercise, the odds ratio of metabolic syndrome and it's components were increased significantly by habitual snoring. HDL-cholesterol, blood sugar, waist size were significantly higher in women, but not significantly higher in men.
