This study was carried out to investigate statistical validity of medical articles that used various statistical techniques such as t-test, analysis of variance, correlation analysis, regression analysis and chi-square test. For study 429 original articles using those statistical methods were selected from Journal of Korean Acupuncture & Moxibusition Society published from 1984 to 2002. 429 original articles were reviewed to analyzed the statistical procedures. Results are summarized as follows : 1. In this study 93 articles(21.68%) of 429 ones didn't report statement of statistical method in detail. 2. 53 articles(12.53%) didn't report p-value in correctly, and 245 articles(57.11 %) used mean${\pm}$standard error (Mean${\pm}$SEM.) and 109 articles used mean${\pm}$standard deviation(Mean${\pm}$SD.). All of 23 articles using nonparametric statistical techniques made an error to central tendency or dispersion. 3. 175 articles(59.93%) and 14 articles(4.79%) of 292 ones made an error to description of equal variances and normal distribution. 4. 99 articles(50%) of 185 ones misused t-test and 4 articles of 5 ones misused chi-square test. 5. 28 articles(73.68%) of 38 ones using discrete variable misused parametric technique such as t-test or ANOVA. 2 articles and 1 article of 125 ones choosing paired samples misused independent t-test and Mann-Whitney U test. 6. 20 articles using analysis of variance didn't use multiple comparison.

The purpose of this research is to find the effect of the lesson using open-inquiry report Lubric on open-inquiry standard and science process skill; to find the change of cognition on open-inquiry for elementary school 5th grade students. Two classes (elementary school 5th grade) were selected which located in a small and medium-sized city for this research and they were separated as an experimental group and a comparative group. Open-inquiry lesson was done by referring teaching method which introduced through the curriculum. The procedure was understanding about open-inquiry, making open-inquiry subject, planning, and performing inquiry, mid-term, performing inquiry, making a report, presentation, and evaluation. Open-inquiry report Lubric which developed by Sook-Kyung Kim et al. (2010) was provided to the experimental group. Comparative group was instructed by using open-inquiry report which introduced to the elementary school 5th grade science text book. Interview paper was developed in order to check out the effect of the research by using a test paper of science process skill. The following could be found out through the research. After open-inquiry lesson, 10 open-inquiry reports(5 reports from experimental group, 5 reports from comparative group) have been drawn at random as samples from the total 62 sets (30 reports from experimental group, 32 reports from comparative group) and evaluated by a researcher and two elementary school teachers who have master degree. The reliability of the 3 scorers was 0.923 of mean correlation coefficient. And then the researcher evaluated all open-inquiry reports. The average score of open-inquiry report was 66.78 for experimental group, 54.27 for comparative group, respectively. And there was a significant difference at p<0.05 level as a result of the t-test. The experimental group rated high at p<0.05 level according to the analysis of post-science process skill test. According to the result of survey, both experimental group and comparative group had understood open-inquiry activity. It was especially rated high for experimental group on understanding scientific inquiry process, interest and satisfaction in open-inquiry and re-participation rate. By interviewing experimental group, it is recognized that the students utilized Lubric very well through the overall process. Finally, self-evaluation was done during open-inquiry activity and it was reported that the students gained more knowledge about science and changed to positive about science. As a result, the lesson using open-inquiry report Lubric was effective for students to improve writing skill of an open-inquiry report and science process skill and finally changed the cognition to positive about open-inquiry lesson.

The purposes of this study were firstly to assess the differences of conflict resolution strategies between friends according to children's peer status, and secondly to investigate the relationship of conflict resolution strategies measured by self-report, hypothetical interview, and observation methods. Thirty-four dayds in elementary 5th graders were selected according to peer status and friendship. Collected data were analyzed tv t-test and Spearman's correlation. The results of this study showed that children's conflict resolution strategies differed according to their peer status. Specially, popular children reported using and experiencing compromising/integrating strategies more than rejected children did. Rejected children reported using and experiencing dominating strategies more than popular children did. Secondly, there were meaningful correlations between compromising/integrating and dominating strategies, as measured by self-report, hypothetical interview, and observation methods. However, no relations emerged among avoiding, obliging, and intervention requesting strategies, as measured by self-report, hypothetical interview, and observation methods.

Purpose: This study aimed to identify the factors influencing nursing students' intentions to report child abuse. Methods: The participants of this study were 151 nursing students who were currently enrolled in nursing departments in Korea and who were at least 18 years of age or older. This study used a descriptive cross-sectional design, and the data were collected from February 16, to March 13, 2023, using an online self-administered survey. The questionnaire included general characteristics, empathy ability, child rights recognition, child abuse perception, and intention to report child abuse. The data were analyzed with descriptive statistics, an independent t-test, one-way ANOVA, Scheffé test, and multiple regression analysis using SPSS Statistics 29.0. Results: The intention to report child abuse showed statistically significant positive correlations with empathy ability (r=.23, p<.001), child rights recognition (r=.34, p<.001), and child abuse perception (r=.63, p<.001). In the multiple regression analysis, the factors significantly related to nursing students' intention to report child abuse were as follows: awareness of mandatory reporting (yes) (β=.16, p=.021) and child abuse perception (β=.56, p<.001). The explanatory power of these factors was 45.0% (F=20.03, p<.001). Conclusion: Considering the findings of this study, it is necessary to develop and implement educational programs for improving the perception of child abuse and thus enhancing nursing students' intention to report child abuse.

Objectives: To report the effect of Sajaehyangbu-hwan on a polycystic ovary syndrome(PCOS) patient with anovulation. Methods: The patient with PCOS was treated by Sajaehyangbu-hwan twice a day. The patient measured basal body temperature(BBT) and took a urine luteinizing hormone test(LH test) for three months to predict ovulation. Results: Two ovulations were observed in BBT and LH test results within three months and the typical biphasic BBT pattern was established. Conclusions: Sajaehyangbu-hwan has an effect on establishing obvious biphasic pattern in BBT of the patient with PCOS and the anovulation caused by PCOS.
