In this study, we compared the differences between groups in a model that investigates the effect of smartphone users on the intent to use continuously. There are various methodologies for group difference analysis, but in this study, we try to verify the size comparison of regression analysis $R^2$. In order to analyze the difference between groups, we try to prove through hypothesis test whether there is a meaningful difference in the intention of continuous use of Korean and Chinese smartphone users collected through previous research. The results of the analysis are useful as a method to determine whether smartphone users in China and Korea are aware of differences or not. According to this procedure, first, the formula for calculating Z-transformation of Fisher and Z-score test statistic calculation formula were used. However, this methodology is also used in the verification of control effect using correlation coefficient. Also, the theoretical implications are presented based on the analysis results.

Purpose: This study is a pseudo-experimental study of design before and after the non-equivalent control group, which was attempted to verify that the application of the ukulele to the elderly has the effects of reducing depression, improving self-efficacy, strengthening social bonding, and improving cognitive function. Methods: 46 (23 in the experimental group and 23 in the control group) participants were selected. The experimental group was provided with three sessions of a music program using eight Ukuleles for the elderly, while the control group was provided with three sessions for the elderly. IBM SPSS 25.0 was used for data analysis, and the independent t-test, 𝑥²-test, and Fisher's exact probability test were performed to verify the homogeneity of the subject's general characteristics. The effect verification after the experimental treatment was analyzed by Fisher's exact probability test, Friedman test, and Mann-Whitney U test. Results: Depression showed a statistically significant difference between the two groups (F=39.88, p<.001), self-efficacy showed a statistically significant difference between the two groups (z=-4.96, p<.001), social bonding showed a statistically significant difference between the two groups (z=-5.19, p<.001), and cognitive function showed a statistically significant difference between the two groups (z=-3.98, p<.001). Conclusion: It was found that the 'Music Program using the Ukulele' was effective in reducing depression of the elderly, improving self-efficacy, reinforcing social bonding, and improving cognitive function. We hope that the Music Program using the Ukulele can be used in the elderly nursing curriculum in the future, and we suggest it should be applied as a nursing intervention to those who are experiencing cognitive decline.

Ceramic filter using energy trapping effect is used bandpass filter at high frequency. In this paper, the resonant points of the symmetrical modes and antisymmetrical modes were theoretically analyed and synthesized these modes in order to know the filter characteristics. We simulated them using the computer and also fabricated the ceramic filter using PZT-4 piezoelectric plate made by Valpey Fisher Co., The 1.5[.mu.m] - thick platinum electrode were deposited on the ceramic plates with the various masks. The characteristics of the fabricated filters were measured using the spectrum analyzer. Experimental data were compared with the theoretical results. The maximum-pass frequencies coinsided exactly. The bandwidths of the fabricated filters were slightly different between theoretical and experimental results. We found that these phenomenon were caused by the stray capacitance between the two neighbor electrodes..

Objective : The purpose of this study is to investigate the factors affecting occupational therapist's job stress through meta-analysis. Methods : In order to achieve the purpose of the study, 15 studies that examined job stress of occupational therapists were selected for analysis. The general characteristics of individual papers and the magnitude of the effect of related variables on job stress were calculated. The effect size of related variables on job stress and sub-factors (Fisher z) were calculated. Results : The results were found that the effect size on job stress was not significant in the variables of education level, salary and age. The largest effect size was found to be turnover intention (ES=1.161). There was no significant effect size in sub-factors of interpersonal conflict, organization system and insufficient job control. There was a significant effects in physical environment, lack of reward, job insecurity, job demand and occupational climate. Conclusion : The results of this study were suggested that an approach depending on sub-factors is needed to reduce job stress of occupational therapists. Satisfaction, burnout, and self-efficacy, which are psychological factors, are considered to be needed a program for psychological empowerment in order to reduce the job stress of the occupational therapist with a medium effect size according to individual sub-factors.

The purpose of this study was to compare the effect of educational smartphone app with the effect of learning using conventional paper material. We developed an educational app for nursing students to learn how to read blood pressure and how to take a pulse. Evaluated was the effect of the app-based education by measuring the short term memory (right after the education), the long term memory (a week later) and the satisfaction. 25 college nursing students participated for the experiment group using the app-based education and 25 for the control group using paper-based education. We applied for statistical analysis Fisher's exact test and Independent t-test. The satisfaction of the app user's appeared significantly higher than that of the paper material user's (t=2.322, p=0.024). The short term memory score was 0.23 points higher in the experimental group (6.46 points) than in the control group (6.23 points), which was not statistically significant (t =0.422, p =0.675). Similar result came for the long term memory (t=1.006, p=0.320). After adjusting for the effect of a college grade using ANCOVA, the effect on memory was significantly higher in the experiment group. There might be differences in learning ability between the experimental and the control groups.

In order to investigate the Possibility of utilizing corm as a seed corm In taro, the corm classified by the weight was planted on April 20, 1984. The effect of weight of corm (30, 50, 70, 90, 110, 130150r and 170g) on the growth, yield, and quality of taro was compared to those raised from cornel.The corm showed a better emergence rate than cermets regardless of its size. The larger the size ofcorm wasi the more the number of leaves developed, and the fisher the yield was. It was consideredthat the higher yield and better quality of taro was obtained by using larger corm as a mother corm( in the following year) due to the increase in the production of large taros.
