Purpose: We interviewed 500 students attending to universities in Gwangju and Jeonnam using a questionnaire. The questionnaire was composed of some questions on general characteristics of the subjects, academic characteristics, health-related behaviors, family function, and drinking problems. Methods: The data collected were analysed with uses of t-test, dispersion analysis, correlations analysis and multi-variate regression analysis. Results: As a result of the simple analysis we found that variables related to drinking problems of college students were religion, family, residence, parents' job, living standard, major, academic year, exercise, parents' drinking, parents' attitude to drinking, drinking quantity, intimacy, conflicts, and upbringing tendency. As a result of the multi-variate regression analysis, we found that the higher intimacy between family members, deterioration in behaviors, family and personal relations, and social functions was statistically significantly low. Conclusion: This study demonstrated that drinking problems of college students had significant relations with intimacy, conflicts and upbringing tendency and suggests that an approach in an aspect of family functions is important to overcome drinking problems of college students.

Background: This study was purposed to analyze the effect of spatial accessibility to the psychiatry department in general hospital on the outpatient visit of mental patients. Methods: Data was provided from the Statistics Korea and Statistical Geographic Information Service, National Health Insurance Service, Health Insurance Review and Assessment Service, and Korea Transport Institute in 2015. The study regions were 103 administrative regions such as Si and Gu. The 103 regions had at least one general hospitals with a psychiatry department. The number of outpatient visit of mental patients in regions was used as the dependent variable. Spatial accessibility to mental general hospital was used as the independent variable. Control variables included such as demographic, economic, and health medical factors. This study used network analysis and multi-variate regression analysis. Network analysis by ArcGIS ver. 10.0 (ESRI, Redlands, CA, USA) was used to evaluate the average travel time and travel distance in Korea. Multi-variate regression analysis was conducted by SAS ver. 9.4 (SAS Institute Inc., Cary, NC, USA). Results: Travel distance and time had significant effects on the number of outpatient visits in mental patients in general hospital. Average travel time and travel distance had negative effects on the number of visits. Variables such as (number of total population, percentage of aged population over 65, and number of mental general hospital) had significant effects on the number of visit in mental patients. Conclusion: Health policy makers will need to consider the spatial accessibility to the mental healthcare organization in conducting regional health planning.

Purpose: This study is descriptive research that confirms breakfast eating habit of woman's college students and related factors. Methods: This investigation took place in August 2010 and was participated 142 students of one woman's college which located in a large city. The contents of the questionnaire consists of general trait, diet trait, life patterns and health states. Results: According to the results of uni-variate analysis, the significant variables of breakfast eating habit are: Recognition of importance of breakfast, spare time before attendance, her parents's breakfast eating habit, times of snack, times of eating out and index of food life style. But, according to the results of multi-variate analysis, the number of the significant variables became narrow and they were: Recognition of importance of breakfast, spare time before attendance and her father's breakfast eating habit. Conclusion: Finally, it can be said that the breakfast eating habit of woman's college student is related to recognition of importance of breakfast, spare time before attendance and her father's breakfast habit strongly. It is necessary to emphasis on the recognition of the importance of breakfast and concerns of parents for breakfast eating habit to improve the regularity of breakfast eating habit for woman's college students' health.

Objectives: The purpose of this study is to identify the relationship of personal hygiene education and hand-washing practices among adolescents. Then the impact of such factors on the hand-washing practices was analyzed. Methods: The data of the 2012 Youth Health Risk Behavior web-based Survey collected by Korean Center for Disease Control was analyzed using SPSS. Total 74,186 of middle and hish school students were included. Uni-variate analysis was done by complex sample crosstabs and multi-variate analysis was done by complex sample logistic regression. Results: The 26.8% of students experienced personal hygiene education. The students of boys, low school grade, coeducation, metropolitan, high school record and high economic status experienced more hygiene education. The hand-washing practices were high in the students with the experience of personal hygiene education. In the factors affecting the hand-washing practice, the experience of personal hygiene education was consistently significant. If students experienced the personal hygiene education, they showed 20~30% more rates of hand-washing practices. Conclusions: Hand-washing practice was high when experiencing personal hygiene education. The personal hygiene education was necessary to improve the rate of hand-washing practices.

For analyzing systems of multi-variate nonlinear equations, the linearized modelling techniques are elaborated. The technique applies Newton-Raphson iteration, partial differentiation and matrix operation providing solvable solutions to complicated problems. Practical application examples are given in; determining the zero point of functions, determining maximum (or minimum) point of functions, nonlinear regression analysis, and solving complex co-efficient polynomials. Merits and demerits of linearized modelling techniques are also discussed.

Through this research of the analysis on the frequency flood discharges regarding basin property factors, a linear regression system was introduced, and as a result, the item with the highest correlation with the frequency flood discharges from Nakdong river basin is the basin area, and the second highest is the average width of basin and the river length. The following results were obtained after looking at the multi correlation between the flood discharge and the collected basin property factors using the data from the established river maintenance master plan of the one hundred twenty-five rivers in the Nakdong river basin. The result of analysis on multivariate correlation between the flood discharges and the most basic data in determining the flood discharges as basin area, river length, basin slope, river slope, average width of basin, shape factor and probability precipitation showed more than 0.9 of correlation in terms of the multi correlation coefficient and more than 0.85 for the determination coefficient. The model which induced a regression system through multi correlation analysis using basin property factors is concluded to be a good reference in estimating the design flood discharge of unmeasured basin.

The purpose of this paper is to represent values of acoustic cues for Korean oral stops in the multi-dimensional space, and to attempt to find possible relationships among acoustic cues through correlation analyses. The acoustic cues used for differentiation of 3 types of Korean stops are closure duration, voice onset time and fundamental frequency of a vowel after a stop. The values of these cues are plotted in the two and three dimensional space to see what the critical cues are for separation of different types of stops. Correlation coefficient analyses show that multi-variate approach to statistical analysis is legitimate, and that there are statistically significant relationships among acoustic cues but Oey are not strong enough to make the conjecture that there is a possible relationship among the articulatory or laryngeal mechanisms employed by the acoustic cues.
