The purpose of the present study was to investigate the relationship between spatial ability and sex-role orientation in children. For this purpose, 303 boys and 293 girls were selected randomly. Spatial ability was measured by Embedded Figures Test. Sex-Role orientation was measured by the Children's Personal Attributes Questionnaire (Spence, Helmreich & Stapp, 1975) which was translated into Korean. An item analysis was done. For the data analysis, a three-way analysis of variance and t-test were applied. The results of the present study showed that 1) spatial ability gradually improved between 10 and 14 years of age. 2) There were no significant differences between girls and boys in the performance on the spatial ability test. 3) Masculinity in girls was not significantly associated with high spatial ability. However, there was a tendency for the masculine girls in the direction of higher spatial scores than feminine girls and undifferentiated girls. 4) Femininity in boys was not significantly associated with high spatial ability. However, there was a tendency for the feminine boys in the direction of higher spatial scores than masculine boys and undifferentiated boys.

Purpose: The study aimed to examine the effects of aroma hand massage on state sanxiety, depression, quality of sleep, and blood pressure levels of palliative patients in hospice. Methods: This study was conducted using a nonequivalent control group with a pretest-posttest design. The participants were 48 palliative patients in hospice (experimental group: 24, control group: 24). The aroma hand massage was given to the experimental group once a day for 5 days. Data were collected between December 2017 to February 2018. Data were analyzed using SPSS 20.0 program with the chi-square test, Fisher's exact test, independent t-test, and repeated measurement analysis of variance(ANOVA). Results: There were significant differences in state anxiety levels (t=2.41, p=.020) and quality of sleep (F=14.29, p<.001). However, significant differences in the levels of depression (t=1.59, p=.119), systolic blood pressure (F=0.37, p=.695), and diastolic blood pressure (F=0.37, p=.695) were observed. The aroma hand massage was effective in improving the quality of sleep and state anxiety levels of palliative patients in a hospice. Conclusion: The aroma hand massage was effective in improving the quality of sleep and state anxiety in a hospice.

Background and Purpose: The purpose of this study was investigate statistical validities of previously reported articles that used various statistical techniques such as t-test and analysis of variance. Methods: To analyze the statistical procedures, 66 original articles using those statistical methods were selected from "Korean Journal of Oriental Medicine(KJOM)" published from 1995 to 2007. Results: Twenty-one articles(32%) did not report correct p-values, 33 articles(50%) used mean${\pm}$standard error(mean${\pm}$SE) and 11 articles(l7%) used mean${\pm}$standard deviation(mean${\pm}$SD). Fifty-two articles(95%) of 55 ones which were tested for normal distribution made an error in describing normal distribution. Seventeen articles misused t-test and 12 articles did not carry out the multiple comparison. Conclusions: The training of researchers with clinical statistics or the participation of statisticians in research design will reduce the significant errors in statistical interpretation of the results.

The weapon systems development has some distinct characteristics in that a big size of government budget (derived from national tax) has been expended frequently and the completion of the development projects seems to take long. Thus, the impact of the potential changes in the required operational capability on the development activities can induce some type of project risks. As such, proper management of project risk has been one of crucial subjects in the weapon systems development. Although a variety of methods can be considered, an approach based on the test and evaluation (T&E) process has been selected in this paper in order to appropriately handle those potential risks. In the study of the underlying T&E process, the safety consideration (for instance, explosiveness) of weapon systems is also included. To achieve the objective of the paper, a step-by-step procedure is first presented in the analysis of the T&E process. Then, to pursue some enhancement on the process, a set of necessary and useful activities are added in terms of risk and safety management. The resultant process is further analyzed and tailored based on a design structure matrix method. The case study of a tank development is also discussed.
