  • 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.

  • 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.

  • 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.

  • Semiconductor manufacturing industry is a high density integration industry because it generates a vest number of data that takes about 300~400 processes that is supervised by numerous production parameters. It is asked of engineers to understand the correlation between different stages of the manufacturing process which is crucial in reducing production costs. With complex manufacturing processes, and defect processing time being the main cause. In the past, it was possible to grasp the corelation among manufacturing process stages through the engineer's domain knowledge. However, It is impossible to understand the corelation among manufacturing processes nowadays due to high density integration in current semiconductor manufacturing. in this paper we propose a canonical correlation analysis (CCA) using both wafer test voltage variables and fail bit counts variables. using the method we suggested, we can increase the semiconductor yield which is the result of the package test.

  • This study is to analyze employment stress and career decision efficacy of undergraduates from engineering and social science department. Research object is 310 undergraduates(engineering department: 164 and social science department: 146) from three colleges in Seoul and Cheju. As a result of testing employment stress and career decision efficacy undergraduates had significant difference according to major and grade. Employment stress of undergraduates from engineering department was more serious than undergraduates from social science department. As a result of analyzing on the basis of grade employment stress of sophomores was more serious than freshmen. Career decision efficacy of undergraduates from social science department was higher than other group. Career decision efficacy of freshmen was higher than sophomore. Employment stress and career decision efficacy showed negative corelation in corelation analysis. This study implies that course educating program should be specialized according to major and grade. This study suggests that we should develop course educating curriculum connecting with major education.

  • Under the changing circumstances of broadcasting, this study aims at the corelation of television drama's rating and television image production techniques, analyzing TV image production techniques and TV rating of drama, the highest rating genre. For this research, 6 dramas were selected as samples except the dramas about history and violence on the basis of the TNS media korea's top 100 of the year 2007. This study analyzed camerawork, shot size, shot duration and scene duration with the contents of replay and manuscript viewing of broadcasting companys' homepages. As the result of the analysis of corelation, TV rating is inverse proportionate to multiple camerawork and shot average duration with a very close relationship, showing no relationship with other variables. The result of this study shows that multiple cameraworks and long durated shots should be avoided for higher TV rating.

  • In general, stress measurement of existent shotcrete lining be used by pressure cells. but, measuring instrument is lost by high pressure at shotcrete lining construction and pressure cell's measurement value have to low believability by natural conditions like curing temperature. In this study, proposed techniques to measure without utilizing sensitive stress sensor in natural condition at point that want stress of shotcrete lining after shotcrete lining construction. Executed numerical analysis to forecast stress level that interact in tunnel shotcrete lining, measured strain of hole by load action through hole in shotcrete lining. 3D FEM(finite element method) is enforced through various parameters curing time of shotcrete lining, thickness, load condition. Different model cases applied by parametic study. As analysis result, it could grasp development possibility of method that propose this time because it could examine corelation with strain by near hole of shotcrete lining and stress about load condition.

  • Objectives : The purpose of this study was to show the corelation between age-related muscular mass and the change of exercise, muscle mass and muscular strength by comparison of muscle strength. Methods : 39 volunteers of all the patients who come to Dangjin health center between May and June in 2009 were classified as group A and group B according to age. Demographic data of these two groups have been done a comparative analysis, using the t-test procedure and linear regression analysis. Results : The results and summarized as follows. 1. Demographic data of these two groups have been done a comparative analysis, using the t-test procedure. As a result the average exercise and the average pulse have a statistically significant difference according to age. 2. Each of average fat, muscle and muscular strength in these two groups have been done a omparative analysis, using the t-test procedure. As a result there is no statistically significant according to age. 3. According to the result analyzed by using linear regression analysis, age have a negative effect on muscle but there is no statistically meaningful. Exercising have a positive effect on muscle and there is statistically significant. 4. Age and Protein diet have a negative effect on Grip strength but there is no statistically significant Conclusions : From this result, it can be assumed that the amount of exercise is decreasing with age, which leads to lose some muscle mass.
