  • This study was conducted to develop a tool to investigate and analyze the educational effect of the school space innovation project, which is being promoted on a large scale at the national level. In order to analyze the educational effect of school space innovation, it is first necessary to analyze the structure of the space altered by the school space innovation. Research and analysis should be possible, so a user survey tool was developed for this purpose. It is expected that the survey tool in this study can be used for pre-investigation in the pre-planning stage of the school space innovation project and as a post-evaluation tool for investigating and analyzing the educational effects of space innovation.

  • Objectives : In this study, we tried to analyze the relationship between effect terms and five tastes in heat-clearing herbs. In order to analyze exactly, we also attempted to extract and refine the effect terms. And finally, we tried to infer the effects of each tastes and suppose new effects of each heat-clearing herbs based on their tastes. Methods : Firstly, we extracted the five tastes and effect terms among the heat-claearing herbs written in Herbology. After that, we divided each effect terms to single meaning term and refined them. We also grouped herbs by tastes and set the effect terms in the order of frequency. So we could analyze the relationship between the tastes and the effect terms and supposed the effect of each herbs. Results & Conclusions : We extracted 7 tastes and 87 effect terms. And they was refined to 63 effect terms. As the result of analyzing the effect terms based the tastes, all of heat-clearing herbs included the effects of heat-clearing and detoxification, regardless of tastes. The herbs which have the bitter tastes, included the effects of drying dampness, fire-purging and blood-cooling. And we supposed new effects in 10 kinds of herbs among them. The herbs which have the sweet tastes, included the effects of blood-cooling and fluid-engendering. The herbs which have the hot tastes, included the effects of inducing diuresis and swelling-dispersing. And we supposed new effects in 2 kinds of herbs, by analyzing the relationship between the tastes and effect terms.

  • A timing signal board which can be used to analyze EA effect for coherent radar systems is introduced. It is capable of generating the timing signals that are needed for EA test about radar systems in real time. Its function to generate baseband target signal makes it easy to analyze EA effect. Because all parameters of timing signals can be changed by software, it is very easy to configure many kinds of test scenarios.

  • In this paper, the process effect on the RMS roughness of the $HfO_2$ thin films grown by metal organic molecular beam epitaxy was investigated. The measured RMS roughness is examined to characterize the surface morphology. In order to analyze the factor effects, the significant factors of both the main and the interaction effects were extracted through the effect analysis. In order to compare the regression model with the variable transformation, the effect of each factor and the model efficiency are calculated. The methodology can allow us to analyze the effects between the process parameters related to the process variability.

  • This study analyzes the impact of Import beer demand on Anti-Japanese sentiment. Recently anti-Japanese sentiment heightened by the media was found to be drastically reducing the consumption of Japanese beer in the domestic imported beer market. Thus, the study used the import demand function of imported beer to analyze the impact of the 'Priming Effect' on the consumption of imported beer by anti-national sentiment, indicating a significant drop in Japanese beer consumption in other countries. Therefore, this study used the imported beer import demand function by country to analyze the impact of the priming effect on imported beer consumption according to anti-national sentiment. As a result, in the case of imported beer consumption in other countries, it was estimated that indirect consumption substitution occurred considerably.

  • The classical continuum theory-based thin film model is independent of their size and the surface effect can be ignored. But the surface to bulk ratio becomes very large in nano-size structures such as nano film, nano wire and nano beam. In this case, surface effect plays an important role and its contribution of the surface effect must be considered. Molecular dynamics simulation has been a conventional way to analyze these ultra-thin structures but structures in the range between submicro and micro are difficult to analyze by classical molecular dynamics due to the restriction of computing resources and time. Therefore, in present study, the continuum-based method is considered to predict the overall physical and mechanical properties of the structures in nano-scale, especially, for the thin-film. The proposed continuum based-thin plate finite element is efficient and reliable for the prediction of nano-scale film behavior.

  • Purpose: This study aims to analyze the inclusive growth in Central Sulawesi Province, an eastern province of Indonesia, up to the districts/cities level. The inclusive growth is analyzed by using Ramos, Ranieri, and Lammens' index that has three indicators which are employment, poverty, and income inequality. Research design, data, and methodology: This study uses panel data of 13 districts/cities in Central Sulawesi Province from 2015 to 2019. The statistical regression used is the panel regression method to analyze the determinants of inclusive growth there. Results: The study found that the average inclusive growth of districts/cities in Central Sulawesi is increasing from the low-level in 2015 to mid-level in 2019. The panel's data regression using fixed effect model FGLS-SUR found Investment (GFCF), Road Infrastructure, HDI, and Processing Industry have a significant positive effect. Regional minimum wage (RMW) has a significant negative effect. Government Expenditure on Education and Health Function has no significant positive effect on inclusive growth. Conclusions: throughout the study period, gini coefficient and poverty rate is slowly decreasing, while employment to population ratio remains volatile in districts/cities of Central Sulawesi.

  • Purpose : The purpose of this meta-analysis was to evaluate the effects of electrical stimulation on patients with non-specific low back pain. Methods : Domestic databases were gathered from studies that conducted clinical trials associated with electrical stimulation and its impact on pain of non-specific low back patients. A total of 681 studies were identified, with 12 studies satisfying the inclusion data. The studies consisted of patient, intervention, comparison, outcome, and study design (PICO-SD). The search outcomes were items associated with low back pain. Cochrane risk of bias 2 (RoB 2) was used to evaluate the quality of 12 randomized controlled trials. Effect sizes (Hedges's g) in this study were computed as the corrected standard mean difference (SMD). A random-effect model was used to analyze the effect size because of the high heterogeneity among the studies. Egger's regression and 'trim-and-fill' tests were carried out to analyze the publication bias. Cumulative meta-analysis and sensitivity analysis were conducted to analyze the effect according to the sample size and the consistency of the effect size. Results : The following factors had a large overall effect size (Hedges's g=1.28, 95 % CI=.20~2.36) involving electrical stimulation on non-specific low back pain. The subgroup analysis all showed a statistical difference in the types of study design, electrical stimulation, and assessment tool. No statistically significant difference was found in the meta-regression analysis. Publican bias was found in the data. Conclusion : The findings in this study indicate that electrical stimulation interventions have a positive effect on patients with non-specific low back pain. However, due to the low quality of studies and publication bias, the results of our study should be interpreted cautiously.
