The objective of this study was to analyze the space usage and user evaluation of community facility in Apartment. This study was conducted case study and questionnaire survey. Four High rise Mixed-use Apartments in and near seoul built in 2000 and later were chosen for case study and 166 residents were collected for questionnaire survey. The frequency, percentage, mean, One-way ANOVA and Duncan tests were executed through SPSS for Win 12.0 statistics package program. The types of community facilities of High rise Mixed-use Apartments were consisted of sports, child care, study, information sharing, leisure/cultural facilities. Most of the community facilities showed to be similar regardless the subject of High rise Mixed-use Apartments. The usage percentage of community facilities increased since the residents have moved to their current residence of High rise Mixed-use Apartments from their previous residence.

Purpose: This study aims to determine what changes occur in body composition and performance by subjecting youth soccer players to weight training and combined training, which are known to be effective in improving anaerobic capacity, for 6 weeks. Research design, data, and methodology: This study was conducted on 30 high school soccer players from S City who had no current injuries or medical problems and had been registered as players with the Korea Football Association for more than 3 years. Subjects were divided into a weight training group (WTG, n=15) and a combined training group (CTG, n=15). Training lasted 6 weeks, and measurements were taken before and after training. Mean (M) and standard deviation (SD) were calculated to present the descriptive statistics of all dependent variables. Paired t-tests were used to test for within-group differences. Further, Independent t-tests were employed to test for between-group differences. Results: In terms of body composition, height significantly increased in WTG and CTG, and body fat percentage significantly decreased in CTG. As for performance, WTG's 20m sprint record decreased significantly. Conclusion: As a result, this study confirmed that weight training improved the 20m sprint ability of youth soccer players. Future research could provide more useful information by extending the study period and incorporating the physical characteristics of adolescents.

In recent years, women's monetary rewards in golf increased and their performances have improved significantly compared to other sports. Sports marketing has become more active in Asia and the number of Korean players in LPGA with good scores are increasing. For these reasons, golf is becoming increasingly popular. The prize money is higher than in other sports and the economic benefits are increasing due to the financial incentives such as sponsorships. Many of these prospects actively affect women's golf. Certain rookies continue to increase and their performances improve day by day. In this study, I analyze the changes in performance over time of last 5 years from 2009 using growth curve analysis.

This study focuses on the prediction and factors of apartment prices in Seoul using a convolutional neural networks (CNN) model that has shown excellent performance as a predictive model of image data. To do this, we consider natural environmental factors, infrastructure factors, and social economic factors of the apartments as input variables of the CNN model. The natural environmental factors include rivers, green areas, and altitudes of apartments. The infrastructure factors have bus stops, subway stations, commercial districts, schools, and the social economic factors are the number of jobs and criminal rates, etc. We predict apartment prices and interpret the factors for the prices by converting the values of these input variables to play the same role as pixel values of image channels for the input layer in the CNN model. In addition, the CNN model used in this study takes into account the spatial characteristics of each apartment by describing the natural environmental and infrastructure factors variables as binary images centered on each apartment in each input layer.

Objectives : The purpose of this study was to investigate the maxillofacial injuries of the sports players' and analyzing the concerned factor. Methods : The subject in this study were 290 sports players' enrolled in Jeolla region. SPSS statistics program(Version 12.0) was used to analyzed the collectde data, Chi-square test and percentage were used as the analysis technique. Results : 1. It was found that 63.8% of all respondents ever experienced trauma in sport activities and 28.6% experienced maxillofacial trauma. 2. In terms of traumatic causality, it was found that most of our respondents attributed the biggest cause of maxillofacial trauma to 'sport activities.' 3. However, it was found that only 12.1% of all respondents gave correct answers to question items about good medical treatment for traumatic odontoptosis. 4. It was found that less than half of all respondents ever faced information on maxillofacial trauma. Conclusions : This finding suggests that it is required to build up current orientation programs about maxillofacial trauma for our sport players. The maxillofacial trauma of sport players' is a important factor that degenerate the quality of the oral health and bring about the change of life style.

Objective: The aim of this study is to verify the differences in muscle characteristics of elite level swimmers before and after a 2-hour practice session. Method: The study was conducted on 15 elite swimmers. Preliminary measurements for each muscle (Anterior Deltoid, Triceps Brachii, Biceps Brachii, Flexor Carpi Ulnaris) were taken using the MyotonPRO device before training. After approximately 2 hours of training, the same muscle areas were measured again. The collected data was analyzed through descriptive statistics and two-way 2×2 RG·RM ANOVA, and all statistical significance levels were set at α=.05. Results: After analyzing the characteristics of the Flexor Carpi Ulnaris (FCU) before and after training in both proficiency level swimmers (excellent, non-excellent), it was found that the interaction effect of group X repetition in muscle tension (F), muscle stiffness (S), and body recovery time (R) was statistically significant. Secondly, in the analysis of the Biceps Brachii (BB), the main effect of repetition in muscle tension (F), muscle stiffness (S), and body recovery time (R) was statistically significant. Furthermore, the interaction effect of group X repetition in muscle stiffness (S) and body recovery time (R) was statistically significant. Conclusion: The efficient use of FCU and BB suggests that it is an important factor distinguishing the performance of excellent and non-excellent swimmers in swimming. Therefore, if we develop and apply measures to efficiently utilize FCU and BB during training, it can help improve the performance of the athletes.
