The purpose of this study is to investigate children's liquid conservation concept according to their ages and task-situations in the water evaporation phenomenon. Thirty from each 4-, 6- and 8-year-old age groups (total of 90 subjects) were selected for this study. The subjects were recruited from two day-care centers, a kindergarten, and an elementary school, in Seoul. Statistical methods used for data analysis were frequencies, percentiles, means, standard deviations and repeated measures ANOVA. As a result, there was a significant difference in children's liquid conservation concept in the evaporation of water according to their ages and task-situations. 8-year-old children showed levels of cognition than 4- and 6-year-olds. Children showed higher levels of cognition in the task of drying than in the task of water level changes.

The purpose of this study was to develop the cultural approach counseling for school adjustment of adolescent. The subjects were 40 adolescents who had randomly assigned to an experimental group(20) and a control group(20). Subjects completed a school adjustment and a style of life. Data analyses were conducted using ANCOVA, ONEWAY of repeated measures. The results of the analyses revealed that subjects of experimental group showed significantly higher scores on style of life and school adjustment than ones of control group. Based upon the above results, it is concluded that the cultural approach counseling for school adjustment of adolescent was effective in improving adjustment of school of adolescent.

For split plot designs exact univariate F tests of the within-subjects main effect are based on the assumption of multisample sphericity. Type I error rates and power are reported for the F test and two tests designed for use when multisample sphericity is violated: the $\widetilde{\xi}$-adjusted test and the Corrected Improved General Approximation(CIGA) test.The results indicate that even though the F test and the $\widetilde{\xi}$-adjusted test have better power than the CIGA test in some conditions, the F test and the $\widetilde{\xi}$-adjusted test do not control Type I error rates when the design is unbalanced and the F test dose not have a good control of Type I error rates when sphericity assumption is severely violated.

Purpose: This study was aimed to identify the effect of abdominal massage on relieving constipation of the patients receiving hemodialysis Method: This study used non-equivalent control group pretest-posttest design. The data were collected from June 30 through July 18, 2008. The subjects of the study were 30 patients; 15 in the experimental group (with abdominal massage) and 15 in the control group(without abdominal massage). The data were analyzed with t-test, $x^2$-test, paired t-test, and repeated measures ANOVA using SPSS 12.0 program. Results: There was a significant difference in frequency of defecation in the experimental group compared to that of the control group. Conclusion: Abdominal massage could be an effective nursing intervention for the management of constipation among patients with hemodialysis. Abdominal massage also can be considered in palliative management for hemodialysis patients with constipation.

Purpose: This study was done to investigate the effects of backrest elevation of 0 degree and 30 degrees that minimize the risk of increasing ICP when CVP is measured. Methods: Subjects were sixty-four patients who stayed in the neurosurgical intensive care unit after brain surgery at two university-based hospitals. CVP, blood pressure, heart rate and ICP were measured along with position changes in order of backrest position with primary 30 degrees backrest position, 0 degree backrest position and secondary 30 degrees backrest position. For data analysis, one-group, repeated-measures analysis of variance design was used in SAS program. Results: Backrest elevations from 0 degree to 30 degrees did not alter the CVP without increasing the ICP. Therefore, 30 degrees backrest position is a preventive position without increasing ICP. Conclusion: 30 degrees backrest position might be appropriate for brain injury patients when CVP is measured.

This study investigated moral judgment and moral reasoning about aggressive behavior by intention, presentation of results of aggressive behavior, and age of child. Forty-four 3-year old and forty-six 5-year-old day-care children in Seoul and Kyonggi Province were interviewed individually with 20 pictorial tasks. Data analysis was by frequencies, percentiles, means, standard deviations, paired t-test, and ANOVA(repeated measures). Both age groups judged instrumental and resentment-based types of aggression to be worse than prosocial or rule observance-based aggression. Both age groups judged aggressive behavior to be worse when results of aggression were presented. Five-year-olds judged aggression to be worse on instrumental than on retributive types of intent. Level of reasoning on aggressive behavior was lowest in cases of satisfying resentment Level of reasoning about aggression increased with age.

This study investigated the effect on children's literacy of teacher-child discussion about the contents of storybooks. The subjects were 10 experimental and 10 control 5-year-old kindergarten children in Cheongju. The experimental design was the Split Plot design. The research instruments used for pre- and post-tests were the Vocabulary Decoding Competence Test(Lee, 1998), Writing Competence Test(Lee & Lee, 1990), Story Comprehension Competence Test(Lee, 1998; Morrow, 1990), and the Emergent Reading Ability Judgements for Favorite Storybooks(Sulzby, 1985). Data were analyzed by ANOVA with repeated measures. Results showed that the teacher-child discussions about the contents of storybooks were effective for improving children's competence in decoding vocabulary, writing, and story comprehension but not for improving emergent reading ability.

Purpose: This study was aimed at identifying the effect of meridian acupressure on decreasing the severity of constipation in stroke patients admitted to the intensive care unit. Method: The data was collected from June 1 to July 30, 2005 at D Hospital in Busan. They were divided into two group: one experimental group of 18, and the another control group of 17. Meridian acupressure was given to the experimental group and no meridian acupressure was given to the control group. The data was analyzed using the t-test, ${\chi}^2-test$, Fisher exact, and repeated measures ANCOVA. Results: There was a significant improvement in frequency of defecation and severity of constipation in the experimental group compared to the control group. Conclusion: Meridian acupressure can be considered an effective nursing method for the management of constipation among Cerebrovascular Accident patients.

Purpose: This study was conducted to investigate the effects of a psychomotorik program on the self concept, sociability and aggression in preschoolers. Method: The research design was a nonequivalent control group pretest-posttest design. There were 34 subjects in the experimental group and 34 in control group among 68 preschoolers in a nursery in the city of G. The experimental group received an 12 weeks psychomotorik. The out come variables were measured before and after the program. Collected data were analyzed by Fisher's exact test, t-test, $X^2$. test, repeated measures ANOVA & ANCOVA using the SPSS 15.0 program. Result: After psychomotorik program, self concept, sociability were increased and aggression decreased in the experimental group. Conclusion: Psychomotorik program was effective in increasing self concept and sociability and decreasing aggression. The program should be effective in psychological development of preshoolers.
