This study was to examine the effectiveness of prefrontal Neurofeedback training by observing the pre and post brainwave measurement results of about Y kindergarten kids 50 (experimental group 25.comparative group 25) subjects who have shown corelation, in between the months of Mar. 2008 and Nov. 2008. As the brainwaves are adjusted by timeseries linear analysis, the result confirmed the differences of both corelation. The result of the study suggest Neurofeedback technique's possibility in positively affecting the subjects' corelation and mental state.

Purpose : To investigate the degree of apearance satisfaction, self-es teem and school maladjustment and the corelation among the three variables in elementary, middle and high school student. Method : The subject of this study was total 878 students of elementar y, midle, and high schol in Seoul. The data were collected through a sel f-administered questionaire f rom June, 18 to June, 29, 2007. Results : The mean of apearance satisfaction was 29.8. Apearance sati according to school, presence of parents, academic performance, and the number of friend. The mean of self-estem was 77.9. Self-esteem showed significant diferences according to grade, academic performance, and the number of friend. The mean of school maladjustment was 54.3. School maladjustment gender, academic performance, and the number of friend. In the corelation among three variables, there was a positive corelation betwen apearance satisfaction and self-esteem but there was a negative corelation betwen appearance satisfaction and school maladjustment, and also a negative corr multiple linear regresion analysis to investigate influencing factor on schol maladjustment, apearance satisfaction and self-estem were significant variables. Conclusion : We should make regular education program and provide students through school classes which help from their parents.

In order to grasp, status of trace metals contained and corelation analysis between cereal and soils, the samples which have been collected from four myeons in Ulju-ku Ulsan-city were 48 for cereal and 48 for soils. The average Hg containing level of samples is 0.006 ppm for cereal and 0.062 ppm for soil, Pb is 0.302 ppm for cereal and 0.885 ppm for soil, and Zn is 7.853 ppm for cereal and 2.366 ppm for soil. Corelation analysis between cereal and soils showed statistical significance for Hg, Pb and Cu, but it didn't show any significance for Cd and Zn.

The purpose of this article is (1) to measure the attitudes of health care consumers towards medical service, the physicians' duty to provide information and patient self-determination options, (2) to discover the their related variables. The attitude of health care consumers towards medical service reveals statistically significant corelation with age and education. Among the statistically significant independent variables it is significantly related with age in the multiple regression analysis. The attitude of health care consumers towards the physicians' duty to provide information reveals statistically significant corelation with age, education and the attitude of health care consumers towards medical service. Among these independent variables it is significantly related with the attitude of health care consumers towards medical service in the multiple regression analysis. The attitude of health care consumers towards patients' self-determination options reveals statistically significant corelation with age, the attitude of health care consumers towards medical service and the attitude of health care consumers towards the physicians' duty to provide information. Among these independent variables it is significantly related with the attitude of health care consumers towards the physicians' duty to provide information in the multiple regression analysis.

Two evaluation techniques of the tunnel lining concrete using ultra sonic velocity method are developed. Modified linear regression technique is proposed to enhance the corelation between the pulse velocity and the compressive strength of core specimens. And bivariate normal distribution is assumed to evaluate the quality of concrete as a terms of compressive strength. A simple corelation table between the pulse velocity and the compressive strength of core specimens are proposed.

In DS-CDMA method, Mobile Stations own jointly one radio channel and are made to use a PN code (Pseudo-Noise Code) for the purpose of minimize interference. However, corelation value of PN code is one when time delay is zero but the corelation value is 1 / N when time delay is not 0. Therefore corelation characteristic does not fully attained. As a result, when the user increase, the performance degradation and system capacity problem will be able to occur by interference among users. In this paper, the PN code has ideally self corelation. It was proved that PN code could depress interference from other users in multiple access system.

Objective : This study was designed for find corelation between behavior and physical symptoms in child. Physical symptoms appearing related with weak viscera are selected. And behaviors related to selected symptoms are compared that of children with character type defined by jung, c. G. Method: 497 children ( 3-11 years old ) who have visited two oriental clinic ( one is in Gang-Nam Gu Seoul (282 children), the other is in Joong-Rang Gu Seoul (215 children) ) from Jan. to Jul. 2006 were invested through the questionnaires, which were filled by their parents. These questionnaires have 61 yes-no type questions about behaviors on 12 situations, 36 yes no type questions about physical symptoms in 15 categories. 6 questions expected positive answer in child with weak spleen are categorized sp-q and 6 related weak lung, lu-q, 6 related weak kidney, ki-q. Numbers of positive answers in sp-q, lu-q and ki-q are counted so-index, lu-index and ki-index each. Corelation between behavior questions and 3 symptom indexes are measured and questions shown low significance level ( under 5% in pearson corelation, two-tailed ) are selected. Result: 15 behaviors related sp-index, 12 related lu-index, 12 related ki-index are selected and analysed. Conclusion : 1. Behaviors related sp-index is similar to that of Thinking Type children Grouped by jung, c. G.. 2. Behaviors related lu-index is similar to that of Sensation Type. 3. Behaviors related sp-index is similar to that of Feeling Type.

지형지물은 각각의 특징적 요인을 내포하고 있다. 이 특징적 요인들은, 공간해상도에 따라 정도의 차이가 있겠지만, 수집된 위성영상에도 반영된다. 이러한 요인들 중에서는 영상분류에 활용될 경우 영상 분류의 정확도를 높혀 주고, 때로는 이것이 거의 물체인식의 수준까지 기여할 수 있는 것들이 있다. 이 연구에서는 텍스춰 및 지형지물의 배열에 있어서 특징적 현상을 보이는 비닐하우스를 대상으로 spatial auto-corelation 개념을 기반으로 자동적으로 이를 인지하는 방법을 개발하였다. 사용된 알고리즘은 디지타이징과 같은 사람의 직접적인 개입이 없이 자동화된 방법으로 비닐하우스의 특정한 패턴이 반복적으로 나타나는 것을 감지할 수 있도록 개발되었다. 패턴의 인식에 더하여 비닐하우스의 기하학적 모양을 고려하는 방법도 도입하였다. 그럼으로써 비닐하우스의 추출에 단순히 화소 단위의 분석이 아닌 보다 객체지향적인 방법으로 비닐하우스를 추출하도록 하였다. 개발된 방법을 제주지역의 IKONOS에 적용시켜 본 결과, 연구대상지역 내의 비닐하우스가 매우 정확하게 적출되었다.

This paper is proposed a wavelet-based MCDT(Mask Coefficient Differential and Threshold) method of image registration of Multi-images contaminated with visible image and infrared image. The method for ensure reliability of the image registration is to the increase statistical corelation as getting the common feature points between two images. The method of threshold the wavelet coefficients using derivatives of the wavelet coefficients of the detail subbands was proposed to effectively registration images with distortion. And it can define that the edge map. Particularly, in order to increase statistical corelation the method of the normalized mutual information. as similarity measure common feature between two images was selected. The proposed method is totally verified by comparing with the several other multi-image and the proposed image registration.

To get legitimacy of a security investment, the analysis of ROI about the security investment is required. In this paper, we suggest a practical quantitative model with considering factors that do decision-making of optimized security investment difficult. This model makes use of the value of a residual risk to decide the best information security solution and considers a corelation of response techniques of the information security solution against each threat to do exact decision-making.
