Purpose: The aim of this study is to analyze and visualize the distribution of patients visiting the periodontology department at a dental college hospital, using a geographic information system (GIS) to utilize these data in patient care and treatment planning, which may help to assess the risk and prevent periodontal diseases. Methods: Basic patient information data were obtained from Dankook University Dental Hospital, including the unit number, gender, date of birth, and address, down to the dong (neighborhood) administrative district unit, of 306,656 patients who visited the hospital between 2007 and 2014. The data of only 26,457 patients who visited the periodontology department were included in this analysis. The patient distribution was visualized using GIS. Statistical analyses including multiple regression, logistic regression, and geographically weighted regression were performed using SAS 9.3 and ArcGIS 10.1. Five factors, namely proximity, accessibility, age, gender, and socioeconomic status, were investigated as the explanatory variables of the patient distribution. Results: The visualized patient data showed a nationwide scale of the patient distribution. The mean distance from each patient's regional center to the hospital was $30.94{\pm}29.62km$ and was inversely proportional to the number of patients from the respective regions. The distance from a regional center to the adjacent toll gate had various effects depending on the local distance from the hospital. The average age of the patients was $52.41{\pm}12.97years$. Further, a majority of regions showed a male dominance. Personal income had inconsistent results between analyses. Conclusions: The distribution of patients is significantly affected by the proximity, accessibility, age, gender and socioeconomic status of patients, and the patients visiting the periodontology department travelled farther distances than those visiting the other departments. The underlying reason for this needs to be analyzed further.

Objectives: Identify the characteristics related to the suicide rates in rural and urban areas of Korea and discover the factors that influence the suicide rate of the rural and urban areas. Methods: Using the data on causes of death from 2006 to 2008, the suicide rates were calculated and compared after age-standardization based on gender, age group and urbanicity. And, in order to understand the factors that influence suicide rate, total 10 local characteristics in four domains - public service, social integration, residential environment, and economic status - were selected for multiple regression analysis. Results: The suicide rates were higher in men than women, in rural areas than urban, and in older people than the younger. Generally, although there were variations according to age group and urbanicity, suicide rates were significantly related to residential environment and regional economic status but not related to regional welfare spending and social integration. In addition, the population over the age of 65 years, only regional economic status has significantly influence on their suicide rates. Conclusions: The influence of characteristics of regions on suicide rate is various by age-group, gender, and urbanicity. Therefore, in order to lower suicide rate and reduce the gap between regions, various approaches must be adopted by taking into account the socioeconomic characteristics of the regions.

PURPOSE. Mandibular flexure is a crucial phenomenon that may affect the success of rigid bilateral mandibular prosthetic treatment. The aim of this study was to determine the amount of median mandibular flexure (MMF) that occurs during mouth opening from anterior to posterior mandible in seven different regions, in different age and gender groups of both dentulous and edentulous subjects, using an intraoral digital scanner. MATERIALS AND METHODS. In this study, the mandibular arch of 56 dentulous and 35 edentulous individuals were scanned with an intraoral scanner at both the minimum mouth opening (MnMO) and the maximum mouth opening (MxMO). MMF values were calculated by subtracting the distance value at the MxMO from the distance between the reference points at the MnMO at seven different mandibular regions of dentulous and edentulous subjects. In addition, the left and right side MMF values were measured. All data were analyzed statistically (α = .05). RESULTS. MMF value increased linearly from anterior to posterior mandible in both dentulous and edentulous individuals. The differences in MMF values were not statistically significant according to side (left/right), age, or gender (P > .05). No significant differences were found between the mean MMF values of the same region in both dentulous and edentulous individuals (P > .05). CONCLUSION. MMF was seen in different regions of the mandibles of both edentulous and dentulous individuals measured at the MxMO. Mandibular flexure should be considered for the success and prognosis of the long-span and rigid prostheses.

Purpose: The purpose of this study was to examine the psychological variables related to sexual issues and sexual violence experiences by gender in university students. Methods: A self-report survey collected responses from 469 university students in three regions. The data were analysed using descriptive statistics, using descriptive statistics, independent t-test, ${\chi}^2$-test, and Pearson correlation coefficients. Results: While male students' scores on sexual assertiveness and sexual assault recognition were lower than female students', their scores on gender role stereotype and sexual violence permissiveness were higher. Female students' sexual violence victims were higher than male students', however, their scores on sexual violence perpetrations were lower than male students'. Sexual violence victims and perpetrations experiences were significantly related to sexual assault recognition and sexual violence permissiveness in male and female students. There were significant relationships between sexual violence perpetrations experiences and gender role stereotypes in male students, while there were significant relationships between sexual violence victims and inflictions experiences and sexual assertiveness in female students. Conclusion: The present study suggests that differentiated programs for preventing or arbitrating sexual violence should be developed and applied by gender because there were differences between male and female students in the level of psychological variables related to sexual issues and sexual violence experiences.

Purpose: The purpose of this study was to estimate income-related health inequalities among adolescent population across regions in Korea. Methods: Data of 8,456 adolescents from 1998, 2001, 2005, 2007 Korean Health and Nutrition Examination Survey were used for the analysis. True health status was proxied by self-rated health and overweight status. Per capita income was computed from household monthly average income adjusted by consumer price with base year 2005. Adolescent health inequalities were estimated by Concentration Index (CI) across income and space. Results: Ill health score was related with age (p<0.0001), gender (p=0.0155) and income (p<0.0001). Negative relationship between income and ill-health indicated that higher income group tended to enjoy better health and less overweight. These evidences suggested ill health were accumulated on the economically disadvantaged adolescents. The size of health inequalities (ill-health score) were estimated as CI=-0.057 and CI=-0.030 across income groups and regions, respectively. Comparable measures of within region health disparities were also observed. Conclusion: Since health disparity among adolescent population was small compared to adult population, lessening adolescent health inequality could be a helpful way of mitigating health disparities in later stage. Considering life stage of adolescents, school system and local communities could play important roles toward adolescent health distribution. Although health disparity between regions existed, health disparity within a region should not be neglected.

It is increasingly clear that student mastery of concepts and skills in geographic education is based on a complex set of variables. Sex and gender are the key variables. Much has been written about biological sex differences in learning, but less attention has been paid to the impacts of socio-cultural gender on learning geography. As such, the aims of this paper are two-fold. First, to examine theories which seek to explain why males and females might differ in their geographic and spatial knowledge or skill. Second, to examine the extent of sex differences and gender traits in the geographic learning. The results of study illustrate clearly that there are more similarities than differences between the sexes. Therefore, there are significant gender differences between the preferences of regions, contents, activities in the secondary geographic learning. The results also provide insights into improving contents and method of geographic education.

This paper studies the relationship between the college entrance examination scores and college mathematics achievements of the freshman, who are the students of college of technology and management in Yanbian University, by employing statistical analysis. First of all, we start from the correlation analysis of the majors and regions of students. Secondly, with gender and region as the classification, we divide the sample into two parts and test the mean significance, and we find that not only different gender but also different region have significant differences to college mathematics achievements. Thirdly, we use the college entrance examination scores as independent variable, and college mathematics achievement as the dependent variable to establish regression model. The model provides a realistic basis for the education department of our school, and provides reference value for the other major research.

The purpose of this study is to explore characteristics of engineering students' everyday creativity compared with those of undergraduate students. For this, we investigated whether there were differences in undergraduates' everyday creativity according to majors, gender and grade. Everyday creativity can be defined as thinking and activities producing useful and suitable personal products, and to solve problems in a new and unique ways. Thus everyday creativity is reported to be universal ability creative people can express in their everyday life. Eight hundred and fifty seven students from three universities in three Korean regions responded to Everyday Creativity Scale. Our findings show that firstly, there were significant differences in undergraduates' everyday creativity by majors and gender. Whereas there were no differences in the same survey by grade. Engineering students obtained significantly lower score of everyday creativity as well as its sub-scales. Also, there were significant differences in everyday creativity's sub-factors by gender. Based on these findings, practical implications for creativity education are discussed with particular attention to learner's individual variables.

Purpose : Using qualitative research and a phenomenological approach, the present study aimed to explore men's experiences of becoming a nurse. We posed the question "What has been your experience of becoming a nurse?" Methods : Eleven male nurses from three regions in Korea were selected through convenience sampling. The protocol suggested by Colaizzi was used for data analysis. Results : The principal themes were "Challenging to the stochastic stereotype of gender mechanics," "Floating outside the enclosure of multiple groups," "The male nurse's conceptualization of nursing organizations," "To stand with self-doubt, thinking of it as a stopover," and "Situations encountered by a male nurse." Conclusion : Men experience gender discrimination based on the social roles that are imposed on males and females both at school and in the workplace. They prefer to work where they have more diverse tasks that require quick responses. However, most male nurses adapt to this work by outlasting the difficulties. These nurses become accustomed to their tasks, and satisfied with their mature work performance. They often feel they are not adequately compensated for their work. They may judge the future as uncertain, and have lingering doubts about maintaining their positions, ultimately gravitating toward specialized fields that promise a brighter future and are more consistent with traditional gender expectations.

The purpose of this study were 1) to describe the rolling movements of the twenties, 2) to identify developmental sequences of three body regions and 3) to evaluate the influence gender might have on the movement patterns used for rolling. Fifty males(mean 23.2 years of age) and fifty females(mean 21.1 years of age) performed the 10 trials of rolling from a supine to a prone position while being videotaped. Individual videotaped trials were classified using the described categories for upper extremity, lower extremity and head-trunk component. The most common combination of movement patterns described. The results of this study were as follows : 1. Only $16\%$ of males and $12\%$ of females demonstrated a same combination of movements during rolling. 2. Gender differences were found in the incidence of movement patterns of each body region. 3. This study determined if head-trunk anion might develop in advance of limb action. 4. This study determined if upper extremity action might develop in advance of lower extremity action. The variability of adults' rolling movement provides physical therapists with numeous movement combinations that might be used when teaching patterns to rolling.
