The purpose of the study was to investigate the total effect size of the domestic adult sandplay therapy, the effect size according to treatment variables such as the total number of sessions, the number of sessions per session, and the dependent variables such as psychological variable group, social variable group, and physiological variable group. To this end, 19 related academic journals and master's and doctorate thesis were selected from 2000 to 2020, and a total of 166 effect sizes were calculated. As a result of the study, the overall average effect size was .749, which was the medium effect size and was statistically significant. As a result of the analysis of the effects according to the treatment variables of the effect size per the total number of sessions was found to be most effective in the 12-session program, and the effect size in line with the number of sessions per week, was described as a medium effect size for both one session and two sessions, but the difference in the effect size was not statistically significant. In terms of the effect size for hours per session, 60 minutes was the most effective. As a result of analyzing the effect of the dependent variables, the effect size of the psychological variables was found to be the most effective. This study proved its effectiveness by conducting a meta-analysis study on sandplay therapy for adults in Korea, and it is meaningful that treatment variables and the dependent variables should be considered when constructing sandplay for adults It is also meaningful in that it provided practical data on the need and development of sandplay therapy to improve mental health and sociality, and physiological changes of adults at psychological counseling and treatment sites.

The study on the high-speed machine tool is very important for the improvement of productivity since it can shortens cutting and non-cutting time. Especially, high speed of feed drive system is the major research field. In the industries of the advanced countries, the feed drive systems at the speed of 60 m/min have been already developed based on the high lead ball screws. In this study, a high speed feed drive system at the speed of 60 m/min has been developed, and its movement characteris-tics arc investigated. As the movement characteristics, positioning accuracy, angular accuracy, straightness and micro step response are measured. Thermal characteristics of the system is also discussed. For measuring the movement characteris-tics, a laser interferometer, a memory-based Hi-coder and a cooling device are used. The experimental results confirm that the movement characteristics and the thermal behavior of the system are satisfactory in the aspect of accuracy and stability.

Six compounds, eupatilin (1), dammaradienyl acetate (2), glutinol acetate (3), 3b-acetoxyoleanan-12-one (4), taraxasterol (5) and quercetin-3,4'-dimethyl ether (6) were isolated from the aerial parts of Artemisia absinthium. The chemical structures of compounds 1-6 were determined by the basis of physico-chemical properties and spectroscopic methods such as 1D and 2D NMR. Among them, compounds 2-5 were isolated from this plant for the first time. The inhibitory effects of these isolated compounds against nitric oxide (NO) production in LPS-induced RAW264.7 cells or BV2 microglia were also examined. Among the tested compounds, compound 1, eupatilin, inhibited the production of NO in LPS-induced RAW264.7 cells and BV2 microglia, respectively.

The accuracy of machine tools is the major factor concerned with the accuracy of the processed work. The feed errors of feed system in machine tool, therefore, make the machining errors of work directly on processing. In this point, this study focused on the generative elements in feed errors of CNC cylindrical grinding machine, such as supporting method of ball screw, the effect of pitch and yaw error and the position detecting method in servo system when operating its shaft of grinding wheel head. Furthermore, in order to improve the accuracy of this machine tool, feed errors are measured by a laser interferometer. Results obtained in this study provide some useful informations to attain high accuracy of CNC machine tool.

In the recent years, development of machine tool with high speed feeding system have brought a rapid increase in productivity. Practically, thermal deformation problem due to high speed is, however, become a large obstacle to realize high precision machining. In this study, therefore, the construction of automatic error compensation system to control thermal deformation in high speed feeding system with real time is proposed. To attain this purpose, high speed feeding system with feeding speed 60㎜/min is developed and experimental equation for relationship between thermal deformation and temperature of ball screw shaft using multiple regression analysis is established. Furthermore, in order to analyze thermal deformation error, compensation coefficient is determined and thermal deformation experiments is carried out. From obtained results, it is confirmed that automatic error compensation system constructed in this study is able to control thermal deformation error within 15~20 ㎛.
