  • The purpose of this study was to analyze a change of maximal grip forces and EMG of agonists in upper extremity of 8 professional Ssirum players according to Satbar-grip patterns, to elucidate prime agonist muscles, contribution rate of each muscle, and a difference on EMG in upper extremity. one-way ANOVA(RM) performed for average and maximal values of each player after standardization and statistical significance was set as p<.05. The result includes the following: the highest grip force was A type with a statistic significance using one-way ANOVA and Duncan's comparison between A and C type. In summary the highest grip force was exerted on extension in the wrist than flexion in all grip types. Average and maximal values of biceps brachii and brachioradialis muscles were statistically significant and ones of flexor carpi ulnaris and extensor capi ulnaris were not.

  • The purpose of this study was to examine the knowledge about savings of customers who utilize Investment Trust Company and to analyze the factors affecting it. The data for the analysis were collected by structured questionnaires and consisted of 191 customers who utilize Investment Trust Company. Descriptive. Descriptive Statistics including percentage, frequency, means, and standard derivation, t-test, one-way ANOVA with Scheffe test, multiple regression analysis were used to analyze the data. The following is a summary of major findings. 1) The customers knowledge about savings showed generally low-level. Especially the knowledge about tax and regulation of savings were the areas shown the lowest level. 2) The age, marital status, education and occupation of customers and total period of utilizing company were the factors affecting the knowledge of customers in the one-way ANOVA analysis. 3) The result of regression analysis indicated that age of customers and total periods of utilizing company were the significant predictors of customers’knowledge. These two variables explained 25.77% of variance of customers’knowledge about savings.

  • The purpose of this study was to analyze group differences of Commitment to career choice and Career stress coping strategy by the Career decision and Career preparation behavior for College Students. Through the results of this study we wanted to look for discriminatory implications for the counseling intervention. The data of 720 college students were collected for the study. The distinction of four types was revealed by the results from Crosstabs and One-way ANOVA. The frequency of upper grades indicated ideal type. But the immature type was fourth grade. There were significant differences in accordance with the two-dimensional typology of Commitment to career choice and Career stress coping strategy by One-way ANOVA. Discussion focused on effective intervention strategies in career counseling based on group differences by the Career decision and Career Preparation Behavior.

  • 국내 온라인 게임은 1996년 바람의 나라를 시작과 1998년 리니지의 성공으로 2020년 오늘날에 이르러 온라인 게임은 국내 게임산업의 중추 플랫폼으로 발전해 왔다. 1999년말부터 2000년대 초반에는 온라인 게임의 태동 시기로 온라인 게임의 수요보다 공급이 부족하였지만 20년이 지난 오늘날에는 많은 수의 온라인 게임들이 시장에 나오고 있어 광고, 이벤트 등 마케팅 활동이 중요한 시기가 되었다. 이에 게임 출시 시기에 따라 이벤트의 중요성이 게임의 성공 여부에 커다란 영향을 미칠 것으로 예상하고, 본 연구에서는 출시 시기에 따라 세 개의 게임을 선정하여 One-way ANOVA을 실시하여 세 게임간의 이벤트의 평균의 차이를 연구하였다.

  • In the one-way random effect model, we often estimate the variance components by the ANOVA method and then estimate the population mean. Whe there are only two distint group sizes, the conventional mean estimator is represented as a weighted average of two normal means with weights being the function of variance component estimators. In this paper, we will study a method which can compute the exact variance of the mean estimator when we set the negative variance component estimate to zero.

  • 이 논문의 목적은 복합레진과 컴포머에서, 중합수축의 양과 이로 인하여 야기되는 교두변위와의 상관관계를 알아보기 위함이다. 수복재료로서 Dyract AP, Compoglass F, Z100, Surefil, Pyramid, Synergy Compact, Heliomolar와 Heliomolar HB가 사용되었으며, 접착제로서는 SE Bond 가 사용되었다. 수복재료의 중합수축의 양을 측정하기 위하여, 자체 제작한 linometer를 사용하여, 60초간 일어나는 선수축량을 측정하였다. 한 수복재료 당 10회 측정하였으며, one way ANOVA와 사후검정방법으로 Tukey Test를 이용하여 $95\%$ 신뢰수준에서 각 수복재료의 중합수축량의 차이를 비교하였다. 치아에서 일어나는 교두변위의 양을 측정하기 위하여 사람의 상악소구치에 표준화된 MOD 와동을 형성하고(깊이 3mm, 넓이 3.5mm), 접착제를 도포한 후 광조사 시킨 후, 수복재료로 충전하였다 치아를 자체 제작한 교두변위 측정장치에 위치시키고, 광조사 시키고, 이 때 발생하는 교두의 변위를 10분간 측정하였다. 한 수복재료 당 15회를 측정하였으며 one way ANOVA와 사후검정방법으로 Tykey Test를 이용하여 $95\%$ 신뢰수준에서 각 수복재료의 교두변위 량의 차이를 비교하였다. 중합수축의 양과 교두변위의 양의 상관관계를 회귀분석법을 이용하여 분석하였다. 중합수축의 양은 Heliomolar, Surefil < Heliomolar HB < Z100, Synergy Compact < Dyract AP, Pyramid, Compoglass F (p < 0.05), 교두변위의 양은 Heliomolar, Surefil, Z100, Heliomolar HB, Synergycompact < Compoglass F < Pyramid, Dyract AP (p < 0.05) 였다. 중합수축의 양과 교두변위는 높은 상관관계를 나타내었다 (p < 0.001).

  • These days, various and complex threads are developed, so it is necessary to develop the cutting a thread sensors for checking a cut thread in severe environment and it is very important to evaluate the quality of the cutting a thread sensors. The analysis of variance(ANOVA) method is very useful method on the quality evaluation field. In this study, the quality is evaluated by one way layout ANOVA method with the surface roughness data. The experiment is carried out by 3 sensors and the result show that the sensors have the good quality in precision.

  • Measures are very useful tools for comparing the shape variability in statistical shape analysis. For examples, the Procrustes statistic(PS) is isolated measure, and the mean Procrustes statistic(MPS) and the root mean square measure(RMS) are overall measures. But these measures are very subjective, complicated and moreover these measures are not statistical for comparing the shape variability. Therefore we need to study some tests. It is well known that the Hotelling's $T^2$ test is used for testing shape variability of two independent samples. And for testing shape variabilities of several independent samples, instead of the Hotelling's $T^2$ test, one way analysis of variance(ANOVA) can be applied. In fact, this one way ANOVA is based on the balanced samples of equal size which is called as BANOVA. However, If we have unbalanced samples with unequal size, we can not use BANOVA. Therefore we propose the unbalanced analysis of variance(UNBANOVA) for testing shape variabilities of several independent samples of unequal size.
