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 purpose of this research is to investigates 10-year trajectories of cognitive functions among older adults in their 70s to understand changes in cognitive functions as a continuum until very late life. This study also examines differences in trajectories of cognitive functions by gender and by changes in marital status, especially widowhood. Among participants of the Korean Longitudinal Study of Ageing(KLoSA), the sample of this study includes 800 older adults in their 70s during the first study wave (2006) and those who reported their cognitive functions for six consecutive study waves (2006, 2008, 2010, 2012, 2014, and 2016). The analyses were conducted in two steps. First, we conducted Latent Class Growth Analyses(LCGA) to investigated heterogeneous trajectories of cognitive functions in 10 years. Then, we performed multinomial logistic regression. Three heterogeneous trajectories of cognitive functions were identified. One group of 48.7% of older adults showed high cognitive function at baseline and maintained it over 10 years. Second group of 14.7% of older adults reported low cognitive function scores at baseline and showed continuous decline over time. Third group of 36.6% were showed mid-level cognitive functions and maintained their functions over time. We also found significant gender differences but not significant differences in marital status when we consider both in our model; however, the we found significant differences in changes in marital status when we did not consider gender in the model. The results suggest that the importance of considering dynamics of gender and changes in marital status to understand changes in cognitive functions in later life.

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.

The study aimed to examine the longitudinal relationship between addictive use of mobile phones and learning activities for elementary school students and to analyze (1)temporal changes of the addictive use of mobile phones and learning activities, (2)temporal relationship between them, and (3)multiple and complex group analysis across gender on the relationship. For the study, 3-year longitudinal data(2010-2012) of the Korean Children and Youth Panel Survey and autoregressive cross-lagged modeling were used. The findings showed that the addictive use of mobile phones and learning activities had a significant positive effect on the future selves of children over time. The addictive use of mobile phones influenced positively subsequent learning activities, but, the learning activities did not affect the addictive use of mobile phones. Further, there were no significant gender differences in the longitudinal relationship. The study provided the useful data to make guidelines on how to protect mobile phone addiction for elementary school students.

Due to the rapid increase in mobile-phone use, various kinds of malfunctions have occurred recently. Among them, the mobile-phone addiction causes serious social problems. In particular, since teenagers are immature, they are easily addicted to new technology. In order to prevent from the mobile-phone addiction, a lot of research has been performed in various ways. This paper focuses on the differences in gender and time perspectives of adolescent and analyze the relationships between time perspectives and self-efficacy for preventing mobile-phone addiction. In order to achieve our research goals, we firstly survey on 1,224 secondary school students to analyze the gender differences about time perspectives. And then, we secondly survey on 269 high school students to examine the mediation role of self-efficacy between time perspectives and mobile-phone addiction by a structural equation model. Based on the results of our analyses, we provide an educational guide that can prevent mobile-phone addiction from secondary school students.

The objective of this study was to investigate the effects of hatch and sex on the body weight and shank length of growing pheasant. Least squares means of body weight at the age of 0, 4, 8, 12, 16 and 20 wks were 17.9, 96.0, 296.4, 563.4, 709.0 and 757.4 g for female, and 18.3, 104.4, 349.1, 728.5, 1001.4 and 1101.6 g for male, respectively. The hatch effect on body weight was significant at the age of 4, 8, 12 and 16 wks (P＜0.05), but the effects on shank length were significant at the age of birth and 8 wks only. There was no significant hatch effect on both the body weight and shank length at the age of 20 wks(P＞0.05). Least squares mean differences between female and male were significant(P＜0.01) over all wks of age except at hatch.

This study was designed to evaluate the Temporomandibular Disorders(TMD) with Tension-Type Headache(TTH) by gender. Patients with TMD and/or TTH visited the Department of Oral Medicine, Kyung Hee University Dental Hospital were recruited to this study. Experimental group(n=60) is composed of TMD with TTH and control group(n=111) is composed of TMD without TTH. Evaluation list was pain quality, pain intensity, pain laterality, pain increase by routine physical activity and then it was analyzed statistically. The results were as follows ; 1. In the control group, pain quality was significantly different by gender(p=0.04). But, in the experimental group, pain quality was not significantly different by gender. 2. In the control group, pain intensity was not significantly different by gender. And, in the experimental group, pain intensity was not significantly different by gender. 3. In the control group, pain laterality was not significantly different by gender. And, in the experimental group, pain laterality was not significantly different by gender. 4. In the control group, pain increase by routine physical activity was not significantly different by gender. And, in the experimental group, pain increase by routine physical activity was not significantly different by gender. Therefore, it is considered that not temporomandibular disorder patients with tension-type headache but temporomandibular disorder patients without tension-type headache was influenced by gender in the pain quality.

Purpose : Our goals were to determine the frequency of headaches and backaches occurring as a side effect following lumbar puncture in children, and to investigate various factors that might influence the frequency of headaches and backaches. Methods : From October 2004 to February 2006, we enrolled 148 patients aged 2 to 15 years who received diagnostic lumbar puncture at the Presbyterian Medical Center, Chonju, Korea. Patient data were collected for age, sex, number of puncture attempts, volume of cerebrospinal fluid(CSF), bevel orientation of puncture needle, cell count in CSF, periods of absolute bed rest, and the frequency and duration of headaches and backaches. Results : Headaches occurred in 8 patients and backaches occurred in 40 patients. Headaches were found both to occur significantly more frequently in patients over age 10 and to last longer when the bevel orientation of the puncture needle was inserted toward the cranium rather than laterally. Backaches lasted longer in males than in females. The other factors evaluated showed no relationship at all to the frequency and duration of headaches and backaches. Conclusion : Following lumbar puncture, headaches were common in patients over age 10, and lasted longer when the bevel orientation was toward the cranium. Backaches lasted longer in males than in females. In light of these findings, we recommend taking special care when performing lumbar puncture for CSF examination in patients over age 10.
