Melody is defined as adding spatial dimension to the rhythm which is temporal concept. Being able to understand melodic pattern and to reproduce the pattern also requires cognitive skills. Since 1980, there has been much research on the relationship between academic skills and music cognitive skills, and how to transfer the skills learned in music work to the academic learning. The study purported to examine various research outcomes dealing with the correlational and causal relationships between musical and academic skills. The two dominating theories explaining the connection between two skills ares are "neural theory" and "near transfer theory." The theories focus mainly on the transference of spatial and temporal reasoning which are reinforced in the musical learning. The study reviewed the existing meta-analysis studies, which provided evidence for positive correlation between academic and musical skills, and significance of musical learning in academic skills. The study further examined specific skills area that musical learning is correlated, such as mathematics and reading. The research stated that among many mathematical concepts, proportional topics have the strongest correlation with musical skills. Also with reading, temporal processing also has strong relationship with auditory skills and motor skills, and further affect language and literacy ability. The study suggest that skills learned in the musical work can be transferred to other areas of learning and structured music activities may be every efficient for children for facilitating academic concepts.

Mathematical, verbal, and spatial abilities are known as three important indicators for the success in the STEM disciplines. In this study, Purdue Spatial Visualization Test-Rotation, College Entrance Scholastic Aptitude Test- Math and Verbal score of engineering freshmen students have been used to find the relationships among these areas. In addition, gender differences in spatial visualization, verbal achievement and mathematical achievement have been investigated, too. In this research, I found that gender difference was highest in spatial visualization ability, followed by verbal achievement and smallest in mathematical achievement. Substantial number of male students possess high level of spatial abilities, but only half of female students were at the same level where their male colleagues were. The correlation between spatial ability and mathematical ability was negligible, contrary to former researches on elementary and middle school students. But the correlation was stronger for female students than male students. The correlation between mathematical achievement and verbal achievement was negative. It reflects the fact that when one section of SAT score is low, score of other sections should be higher to get admitted to college. Gender difference in mathematics was smallest for high achieving spatial ability group. For low spatial ability group gender difference in mathematics achievement has been observed, too. To find the combined contribution of spatial and verbal abilities to mathematics achievement, students were divided into 4 ability groups. Mathematics achievement decreased in the order of (1) high spatial -low verbal group, (2) low spatial - low verbal group, (3) high spatial - high verbal group, (4) low spatial - high verbal group.

The main purpose of the paper is to examine the spatial characteristics of school choice through residential mobility by conducting a correlation analysis on the relationships between the middle schools' entrance rates to special high schools and the elementary schools' net transfer rates. Analyses are done at both the individual school level and the school catchment area level. Prior to the calculation, the two variables involved in the correlation analysis are transformed via a standardization equation, and the standardized scores are mapped and explored. Both the global and local correlation analyses are done for the standardized variables. Main findings are twofold. First, the global correlation analysis reports that there exists a statistically significant correlation between the two variables at both the analytical levels. Second, albeit the prominent positive correlation at the global level, the local analysis reveals the existence of a considerable level of spatial heterogeneity in terms of bivariate association. While several school catchment areas with very high local correlation coefficients (the HH association type) are popped up, other areas with various types of bivariate association including ones even opposite to the global trend are also observed.

우리나라는 산림은 단순림이 많고 밀도가 높기 때문에 산불이 한번 발생하면 대형 산불로 확산될 우려가 크다. 이 때문에 산불 발생을 미리 예측하여 대응할 필요가 있다. 산불 발생예측을 위해서는 산불 발생에 영향을 미치는 인자와 산불 발생의 관계를 파악하는 것이 중요하다. 본 연구는 1997년부터 2006년까지 발생한 전국에서 발생한 산불의 point data를 이용하였다. 산불 발생 지점의 지형인자와 지리인자, 그리고 산불 발생 당시의 기상인자로 DB를 구축하고 산불 발생과의 관계를 구명하였다. 지형인자 분석은 고도, 방위, 경사에 따른 산불 발생 빈도를 분석하였고, 그 상관관계를 분석하였다. 지리인자 분석에서는 인구밀도, 산불 발생지역의 접근성(도로에 따른 접근성, 대도시와의 거리에 따른 접근성)에 대한 산불 발생의 상관관계를 분석하였다. 기상인자와 산불 발생의 관계는 전국 76개소에서 관측된 온습도 데이터를 보간한 자료와 산불 발생과의 관계를 분석하였다. 기상인자 분석은 산불이 가장 빈번하게 발생하는 3월 하순, 4월 초순, 4월 중순 자료를 평균하여 산불 발생 빈도와의 상관관계를 분석하고 산불 발생 위험지역을 도출하였다. 본 연구를 통해서 각 인자와 산불 발생의 관계를 분석해보았다. 하지만 각 인자간의 관계를 분석하지 못한 것이 한계점이라고 할 수 있다. 차후 연구에서는 각 인자간의 관련성을 분석하고 산불 발생의 원인과 인자간의 구체적인 인과관계를 밝히는 것도 필요할 것으로 보인다.

Korea's housing structure is predicted that one-person housing will be the most common type of housing in Korea. Therefore, this study intends to derive contents for designing a one-person housing space considering the life of a rapidly increasing one-person householder. For this purpose, this study objectively derives the social, economic and cultural influencing factors of one-person households through big data analysis, and analyzed the correlation between contents using social network analysis methodology. In this paper, 60 core contents related to one person housing space were derived by applying big data analysis methodology. And through social network analysis, the most influential contents were derived from the space editing and space composition categories. This means that the residential space is an important part of the design idea that can flexibly respond to changes in the user's life. Based on this study, future research will focus on the concept and design methodology of one-person housing space.

This research investigated the relationship between MMORPG players' leadership-related game experience and offline leadership using online survey samples(N=664). According to the correlation results, MMORPG players' leadership-related game experience, age, game usage time and offline leadership exhibited a significantly positive relationship. When players had more leadership-related game experience, they reported higher offline leadership scores. In terms of "spillover effect", more valuable implications of using MMORPGs are discussed in conclusion.

자기지전류 탐사의 적용에 있어 인공잡음의 영향은 탐사의 승패를 좌우하는 중요한 요소이며 인공잡음의 영향을 최소화할 수 있는 탐사의 설계와 자료처리가 요구되고 있다. 본 연구에서는 수치공간자료를 이용한 공간모델링을 통해 MT 주파수 대역에서의 잡음을 예측하고 실제 탐사 자료와 비교분석하여 MT 잡음 모델링을 가능성을 살펴보았다. 수치지도로부터 추출된 잡음원일 가능성이 높은 건물, 도로, 고압 송전선에 의해 발생하는 전자기장의 강도를 지하매질의 전기전도도에 따른 전자기파의 전파 특성을 고려하여 예측하는 잡음모델을 제안하였다. 제안된 잡음모델로부터 예측된 잡음 파워와 실제 탐사를 통해 측정된 MT 자료와의 상관도 분석을 수행한 결과, 전반적으로 전기장에서는 넓은 주파수 대역에서 높은 상관관계를 보이는 반면 자기장은 60 Hz 부근의 대역에서만 상관관계를 가진다. 본 연구에서 제안된 공간모델링을 통한 잡음 예측은 특히 고도로 산업화되어가는 도시 주변지역에서의 MT 탐사를 수행하는데 있어 유용한 정보를 제공할 수 있을 것이다.

In the present age, the quality of MT(magnetotellurics) data highly depends on the level of industrial interference in data. We analyzed the correlation between the spatial distributions of man-made EM noise source and the characteristics of MT data. The noise source analysis shows the correlation between the noise source density and the power spectral density of measured magnetic field in the frequency band of 60 Hz harmonics. In the MT 'dead band', the strong polarization observed on the magnetic field reveals that the severe artificial noises are caused by the adjacent metropolis.

A analysis on the spatial features is required for exploratory spatial data analysis of information about space location(population ecological factor, social ecological factor) to manage the store factors, the service industry, etc. Therefore, the purpose of this study is to provide correlation analysis method between the types of service trade using dependence between spatial objects on the geographical space and statistical correlation and to analyze the spatial features through the deduction of correlation analysis between the types of the neighborhood trade area.
