이 연구에서는 경찰의 조직적 특성 중 경찰관서의 규모에 따른 스트레스 수준을 비교 분석하고자 하였다. 경찰관서 규모에 따른 스트레스 수준의 차이를 살펴보기 위해 독립변수는 관서규모와 급지, 종속변수는 생활 스트레스, 직무 스트레스, 외상성 스트레스로 구성하여 일원변량 분산분석(One-way ANOVA)을 실시하였다. 그 결과 관서규모와 급지 둘 다 직무 스트레스와 외상성 스트레스에서 통계적으로 유의한 수준의 차이가 발견되었다.

This study explored the instrumental values of homemakers by object family living and other social living. Homemakers' instrumental values on family living were compared with those on other social living. Through this it make to explain differences in instrumental values on 2 objects. 650 homemakers were adapted as data. The data were analyzed by frequency percentage means one-way ANOVA duncan-test and paired T-test The results showed significant differences in instrumental values by objects.

Prior studies were limited in the comparison of false belief tasks with desire tasks due to lack of consideration of level of executive functions. To compensate for this, executive functions were included in new preference-related and game-related tasks of conflicting desire. These tasks were administered to 246 preschoolers ranging from 2.5 to 4 years of age. Statistical analysis was by one-way ANOVA and repeated measures ANOVA. Results showed significant main effects depending on age and task type. Younger children lacked ability of executive function, such as inhibition and working memory. Older preschoolers averaged better scores on task performance, showing that it is difficult for younger children to control their own desires and select the contradicted view.

As Industrialization gets more and more advanced, human technological medical apparatus for dentistry has been developed. Such a medical apparatus have to let precision revolution and torque control facilitate. Consequently, Development of Micro hand-piece with strong durability should be required. Moreover, It's also very important to evaluate performance of such a Micro hand-piece, Evaluation of Mechanical property of Material and ANOVA have been known as useful methods in the field of Quality Evaluation. For Verification of Quality Evaluation, It has been evaluated by One-way layout ANOVA based on the data of Surface Roughness Test. Anyhow, This test has been respectively carried out by 3 kinds of Test and Superior performance has appeared in the Test result.

Purpose: This paper is to analyze motivation and behavior of alcohol use of employees, and effects of social pressure on alcohol use of employees. Methods: A cross-sectional study was performed with 341 employees in Industrial Complex. Data were collected from June 26, 2007 to July 11, 2007. Collected data were analysed through Frequency, ANOVA, One-way ANOVA test. Result: Social motivation showed the highest mean among motivation of alcohol use, man showed higher mean than woman on confirmity motivation and affirmation motivation. Dangerous alcohol use showed the highest mean among behavior of alcohol use, man showed higher mean than woman on behavior of alcohol use. Effects of peer showed higher mean than effects of family, generally the more high effects of peer is, the more higher confirmity motivation, dangerous and dependent alcohol use showed. Conclusion: Therefore, to decrease alcohol use of employees must be prepared an alternatives to change drinking culture and recognition, and developed for working man and individual workplaces.

This study is attempted to propose an appropriate number of measurements by checking and statistically analyzing the change in hardness according to the number of measurements. As a result, there was no significant difference between the 20th and 30th data, and in the 10th case, the effect on errors occurring during measurement was found to be dominant. Therefore, as the number of measurements, proposing 20 times in consideration of the convenience of use. In addition, in order to minimize the effect on the measurement error, it is proposed to remeasure the surface mane of the measurement surface and the test value in which the error occurs on the average of the test values.

The CAI (Computer-Assisted Instruction) system for science teaching has been increasing both in quantity and in quality during the last two decades. However, science learning by computer has not played a leading role in the science teaching process. Therefore, the purpose of this study was to analyze the effectiveness of tutorial CAI programs according to the learner's characteristics such as sex, inquiry skills, attitudes toward science subject, logical thinking skills, achievement motivation, science content achievement in science teaching. One group pretest-posttest design was used as an experimental design. The three tutorial science CAI programs were used for thirty males and females selected in grade eight. According to the analysis of CAI achievement scores the female students showed significantly higher (P<0.05) than the male students. Also, one-way analysis of variance was used to investigate the effects of interaction between sex and achievement motivation. The significant difference on the effects of interaction between sex and achievement motivation has not found. The effects of tutorial CAI between logical thinking skills, attitudes toward science subject, inquiry skills, achievement motivation, science content achievement according to upper and lower levels were investigated by using the statistical analysis of one-way ANOVA. The results indicate that tutorial CAI might provides a good opportunities for the improvement of science achievement to the lower level students of attitudes toward science subject, inquiry skills, science content achievement.

Objectives : The purpose of this study is to investigate the effect of object size and reaching distance on kinematic factors of the upper limb while performing arm reaching for normal subjects. Methods : The subjects of this study were 30 university students who were in D university in Busan, and the measuring tool was CMS-70P(Zebris Medizintechnik Gmbh, Germany), a three-dimensional motion analyzer. The task had six conditions. The average velocity of motion, average acceleration, maximum velocity, and the velocity definite number of movements were measured according to changes in object size(2cm, 10cm) and reaching distance(15%, 37.5%, 60%) when they performed arm reaching. The general characteristics of the subject were technical statistics. One-way ANOVA measurement was used to compare variables when the arm reaching task was performed from two object sizes to three reaching distance, and the post-test was conducted with Tukey test. In addition, an independent t-test was used to analyze the kinematic differences according to the two object sizes at three reaching distances. A two-way ANOVA measurement (3×2 Two-way ANOVA measurement) was performed to identify the interaction of the reaching distance(15%, 37.5%, 60%) and the object size(2cm, 10cm). The statistical significance level α was set to .05. Results : When the size of the object increased, the velocity and maximum velocity also increased, but the definite number of velocity decreased. When the reaching distance increased, the velocity and maximum velocity increased, whereas the definite number of velocity decreased. Conclusion : The clinical significance of this study could be utilized as the baseline data for grading object size and reaching distances when the reaching training is implemented for patients whose central nervous system was damaged.
