In this paper, we present effective methods for automatic music recommendation system which automatically recommend music by signal processing technology. Conventional music recommendation system use users’ music downloading pattern, but the method does not consider acoustic characteristics of music. Sometimes, similarities between music are used to find similar music for recommendation in some method. However, the feature used for calculating similarities is not highly related to music characteristics at the system. Thus, our proposed method use high-level music characteristics such as rhythm pattern, timbre characteristics, and the lyrics. In addition, our proposed method store features of music, which individuals queried, to recommend music based on individual taste. Experiments show the proposed method find similar music more effectively than a conventional method. The experimental results also show that the proposed method could be used for real-time application since the processing time for calculating similarities between music, and recommending music are fast enough to be applicable for commercial purpose.

This study has attempted to investigate the time use of the elementary school students and their satisfaction levels by their general characteristics for the educational guidance. The sample of this study consisted of 387 elementary school students on Jeju Island who are in the fifth or sixth year. The data were analysed by frequency, percentage, mean, t-test, ANOVA and Duncan's test. The major results of this study were as follows; The results of this study showed that the students spent much time for studying including extra programs as like their ages. Also, their leisure time focused on watching TV or doing computer. The levels of satisfaction according to the time use were slightly high although their time allocation was not various. The time use of the students and their satisfaction levels were significantly affected by the general family situation related to parents as well as their own characteristics. The variables such as the student's sex, parent's educational level, whether the mother is employed or not, and monthly allowance were important to result in the differences of the time use and satisfaction levels among the students. The leisure time was strongly related with the satisfaction levels.

Background: This study was conducted to analyze the influence of socioeconomic characteristics of community on the food insecurity under the control of personal socioeconomic factors which may be influence to the food security. Methods: Food insecurity and individual socioeconomic characteristics were obtained from 2012 community health survey. Socioeconomic characteristics of communities were extracted from the data of Statistics Korea and local governments. Personal socioeconomic factors were sex, age, educational status, job, and monthly family income. Socioeconomic characteristics of communities were administrative district (urban vs. rural), senior population rate, degree of financial self reliance, degree of financial independence, portion of welfare budget, number of welfare facilities, and unemployment rate. We analysed the relationships between the food insecurity and socioeconomic characteristics of community using multi-level analysis under the control of personal characteristics. Results: On personal level age, sex, education status, and monthly family income were related with food insecurity. On community level administrative district (urban vs. rural), degree of financial independence, unemployment rate, and proportion of welfare budget among local general government accounts were related to individual food insecurity. Rural area, district with low levels of financial independence, low portion of welfare budget, and greater unemployment rate showed a higher level of food insecurity. Conclusion: To reduce the level of food insecurity in a community it is necessary to decrease the unemployment rate, in addition to providing support from the central government by increasing the proportion of the welfare budget so that both factors contribute to raising the degree of financial independence.

The purpose of this study is to consider students′ scholastic relationship in mathematics between elementary school and middle school from the 3rd grade in elementary school to the 2nd and the 3rd grades in middle school. The following are the results: 1. CONCLUSIONS 1. Students′ present scores are most closely related to those of their previous grade. The data are based on the two groups of the 3rd grade middle school students - one is honhappan(mixed students from different elementary school) and the other shinaepan(the students from the same elementary school in kong ju city). This close relation between present and previous scores in mathematics may well be reasonable since mathematics is systemized hierarchically. Among the score data in elementary school, the scores in the 5th grade are meaningfully related to present score data in mathematics. 2. Two pans (as I mentioned above, honhap and shinae) are divided into groups and their scores are traced from the 3rd grade in elementary school and the data show that the high-levelled students have little changes in their scores, but low-levelled students have dropped radically in their scores from the first grade in middle school. 3. In terms of students′ interests, students who answered, "I′m very interested in mathematics." have no distinguished characteristics in their scores while those who answered, "I have little interest in mathematics" shows a decrease in their scores. 4. Among the reasons for their lack of interests, the replies are "because of exams," "because of teaching methods," and "because of the textbooks." II. Suggestion To compensate the limitation and difficiency of this study, the foll owing is suggested for the following studies related to this one. 1. This study was limited to gathering students′ score data from female students in a small city. For a more accurate statistic a bigger population is needed as well as varied geographical and social economical area is suggested. A good idea is to study homogeneous sex groups as well as heterogeneous sex groups 2. It is easy to find out what grade is closely related to the present scores by statistical analysis, but the reasons for their relationship have to be found out through the following studies 3. There are many studies on cognitive domain in math but it is expected to have more studies on affective domain as well.

Objective : The purpose of this study was to evaluate the factors associated with the experience of bullying victimization in school among elementary school students in the Jeju area. Methods : A total of 662 students were recruited from elementary schools for a school-based cross-sectional survey (age range : 11-12 years) in the Jeju area. This study used a self-reported questionnaire concerning the experience of being victimized by bullying, the Korean form of the Children's Depression Inventory (CDI) to assess depressive symptoms, and questions on sociodemographic characteristics, including school- and family-related factors. Results : The prevalence of bullying victimization in school among elementary school students was 10.0% (n=66). The factors associated with bullying victimization were lower socioeconomic status, lower than average academic achievement, more depressive symptoms, and family problems. Conclusion : This study not only indicates that bullying at school is a significant public health issue among elementary school students, but also confirms that children with family problems commonly exhibit bullying behaviors, which highlights the importance of considering family-related environmental factors when managing bullying victimization.

Background: Health is affected by various local factors. This study aims to investigate the age-standardized mortality variation of Seoul as well as the characteristics of the factors related to the mortality variation. Methods: The Korea Community Health Survey data, Seoul Survey data, Seoul statistics, and e-regional indicators of the National Statistical Office were used. To investigate the basic boroughs standardized mortality variation in Seoul, external quotient, coefficient of variation (CV), and systematic component of variation (SCV) values were suggested; correlation analysis and multiple regression analysis were conducted to investigate the characteristics related to standardized mortality rate. Results: The highest and the lowest standardized mortality rate of Seoul by boroughs had as much as 1.4 times difference; a low level of variation was shown in CV by 8.2; and was shown in SCV by 79. As a result of the multiple regression analysis of the factors that affect standardized mortality variation, the higher the rate of householders with college or higher, the lower the standardized mortality rate, and the higher the high-risk drinking rate, the higher the standardized mortality rate. Of the two, the rate of householder with a degree equivalent or higher than college was shown to have the biggest impact, followed by high-risk drinking rate. Conclusion: We found a variation in age-standardized mortality rate of boroughs in Seoul. The results suggest that policy makers should take into account socioeconomic environmental characteristics of community in developing community-based health promotion rather than focusing on lifestyle changes of residents.

Demands and attempts to express Korean traditional beauty are increasing. Some schools choose the uniform in designs expressing the image of Hanbok, but recently there is a few increment of wearing the uniforms. For the improvement of the uniforms, first of all, the shape and the clothing materials of the uniforms should be considered. We have compared and analyzed the shape and the clothing materials of the uniforms reflecting the image of Hanbok, according to seasons and clothing items. The uniforms reflecting the image of Hanbok were worn in eight schools and all of them are Saenghwal Hanbok style. The shape of Saenghwal Hanbok school uniforms showed both Korean style and western style characteristics. Korean style characteristics were expressed through the appearance-related parts while western style characteristics showed through the performance-related parts such as open/closure method, armhole pattern and straight sleeve line. It was shown that girls' uniforms are more diverse and similar to the western style uniforms than boys' uniforms. It was found that most of the clothing material were synthetic fiber or mixture of natural/synthetic fiber, and polyester was shown to be used most.

Objectives : Non-cardiac chest pain (NCCP) can be divided into gastroesophageal reflux disease (GERD) related NCCP and non-GERD related NCCP. Our study was designed to examine the differences in clinical characteristics and psychological mood states between the two clinical syndromes. Methods : After some cardiologic evaluations such as treadmill exercise, coronary angiography, and echocardiography, 27 patients with NCCP were enrolled in this study. They were divided into patients with GERD related NCCP (12 patients) and those with non-GERD related NCCP (15 patients) using the upper gastrointestinal endoscopy and the ambulatory 24 hour esophageal pH monitoring. Clinical characteristics such as typical reflux symptoms and psychological mood states were measured. Patients who showed scores more than 10 on the Beck Depression Inventory (BDI) or Beck Anxiety Inventory (BAI) were defined as depressed or anxious group. Anxiety sensitivity Index (ASI) was also measured in all patients. All parameters were compared between patients with GERD related NCCP and those with non-GERD related NCCP. Results : The two groups showed a difference in typical reflux symptoms. Patients with non-GERD related NCCP had higher scores on the BDI, BAI and ASI than those with GERD related NCCP. Among all NCCP patients, 14 patients (51.9%) were suggested to have possible depression or anxiety disorders. Conclusion : The non-GERD related NCCP was shown to be associated with psychological mood states such as anxiety and depression. Thus, we suggest that routine measurement of psychological mood states should be necessary in the evaluation and treatment of NCCP.
