We introduce an arbitrary waveform generation method and its H/W implementation case based on Rademacher and Walsh function. According to the orthogonal and periodic features of Rademacher and Walsh function, simple calculations can generate arbitrary waves with affordable logics. We implemented an FPGA-based AWS using above two functions, and verified. HDL simulation shows the proposed idea can draw desired analog test waveforms very fast, and its H/W size is promising to Built-Out Self-Test(BOST) logics for AI ICs.
This study was to investigate the current prevention Mechanism of tuberculosis infection and to find out how nursing teachers handle against tuberculosis infection. The objectives of this study was to aid in better treatment and maintenance of those infected-students and help students to prevent the disease by themselves. The subjects of this research were 78 students who were proved to be infected at tuberculosis by the test result of each high school and 35 nursing teachers who retain those 78 infected students. The results of this study were as follows: 1. The infection rete of tuberculosis and the general characteristics of the infected students at Girls' High School: There are approximately 33 and 50 tuberculosis-infected cases in 1992 and 1993. The tuberculosisinfection rate were 0.12% in 1992, while the infection rate were 0.17% in 1993. The infection rate for academic Girls' High School stucents were 51.3%, while that of vocational Girls' High school students were 48.7%, About 30.8% of respondents have a family history of tuberculosis infection. 2. The current management system of tuberculosis treatment: It was reported that 59.0% of respondents out of total cases were in the process of treatment, and 41% of them were recovered (from tuberculosis). 55.1% of respondents use health center as their most frequent treatment location. 57.5% of academic Girls' High School and 47.4% of vocational Girls' high shool reported inconsistent meals while curing tuberculosis. In terms of taking medicine, 55.1% reported inconsistently. 3. The current management system of nursing teachers; Approximately 57.1% of nursing teachers were at academic Girls' High School. while 42.9% were at vocational Girls' High School. While treating tuberculosis, 85.7% of nursing teachers checked the consistent medicine-taking, 54. 3% of them checked the side effects of medicine, 80% of them consulted with students, while only 25. 7% of them check the school attendance. This study also finds out that we have underestimated the importance of tuberculosis treatment and health education at the shool level, it has not been effective enough for students to recognize the importance of tuberculosis. It is our assertion that nursing teachers should have paid much more attention to tuberculosis itself and infected-cases.
Purpose: The purpose of this study was to identify health promotion behaviors of elementary school teachers and investigate the factors influencing the health promotion behaviors. Methods: Data were collected from 234 elementary school teachers in the B Metropolitan City Office of Education from 5th to 30th October, 2016. The collected data were analyzed by descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Mann-Whitney test, Kruskal-Wallis test, Spearman correlation coefficient and multiple regression analysis, using SPSS/WIN 23.0. Results: The elementary school teachers' health perception scored 2.94 out of 4, health status 1.59 out of 3, and health promotion behaviors 2.66 out of 4. The level of mental health status (1.67) was higher than that of physical health status (1.54) and the most practiced health promotion behavior was spiritual growth (3.15) and the least was health responsibility (2.00). Significant negative correlations were found between health perception and health status (r=-.59, p<.001) and between health status and health promotion behaviors (r=-.41, p<.001). A significant positive correlation was found between health perception and health promotion behaviors (r=.32, p<.001). The significant factors influencing health promotion behaviors were job stress and health status. These factors explained 19.6% of the health promotion behaviors. Conclusion: It is necessary to establish measures to increase the health perception and health promotion behaviors of elementary school teachers and improve their health status. In addition, since job stress and health status are factors influencing health promotion behaviors, it is necessary to actively manage job stress and health status in order to increase health promotion behaviors.
Purpose: The purpose of this study was to identify the relationship of the school organizational climate with perceived discrimination and the workplace violence among school health teachers. Methods: The research design was a cross-sectional study. The subjects of the study were 350 school health teachers with more than one year of teaching experience. Data were collected online using a questionnaire. Research variables are general characteristics, organizational climate, perceived discrimination, and workplace violence. The relationship between organizational climate and perceived discrimination and the relationship between organizational climate and workplace violence were analyzed using regression analysis. Results: The score for organizational climate of health teachers was 3.10 out of 5 points, the score for perceived discrimination was 2.85 out of 5 points, and the experience rate of workplace violence was 16.9%. School organizational climate was related to both workplace violence and perceived discrimination. The subcomponents of organizational climate affecting perceived discrimination of health teachers were interrelationship and the level of compensation. The subcomponents of organizational climate affecting workplace violence of health teachers were interrelationship and autonomy. Conclusion: The improvement of the school's organizational climate can reduce the level of workplace violence and discrimination against health teachers. It is important to establish an appropriate evaluation system for health teachers and to recognize the role and expertise of health teachers. In addition, it is necessary for school administraters to actively support health teahcers and to create an organizational climate where they can be friendly and communicative.
Large scale earthquake was occurred in different parts of the world like Japan (in 1995), Republic of Pakistan (2005), in China (2008) etc and enormous structures were damaged. As a result of collapse of school buildings structures numerous students are died and it had a big impact on the international community. Therefore, the interest of preparing the seismic resistant school building structures in our country is increases as school building are used as emergency shelter for local residents. But the current standard of seismic design ratio of 3.7% is applied for school building in Korea which is only significant earthquake damage is expected. In order to overcome the current situation, seismic performance evaluation is carried out for the existing school building and an accurate and appropriate seismic retrofit is required based on performance evaluation to upgrade the existing school buildings. In this paper, nonlinear analysis on existing school buildings for ATC-40(Applied Technology Council, ATC) and FEMA-356(Federal Emergency Management Agency, FEMA) are carried out using the capacity spectrum method to evaluate seismic performance and to determine the need for retrofitting. In addition, after reinforcement to enhance the seismic performance is applied the seismic performance evaluation is carried out to verify the effectiveness of seismic retrofit.
The purpose of this study was to provide basic data needed to establish a system of career education which can offer necessary information for middle school students to select vocational high schools suiting to their talent and aptitude. For this, the study formulated research questions: how middle school students in Gyeonggi-do could acquire information related with entering high school; their level of understanding about general high school and vocational high school and their level of information requirement; real state and effect (level of helping them choose future school) of assistance activity for career education as provided by vocational high schools. For the analysis, the study developed a questionnaire and conducted survey for 4,459 3rd graders from 627 middle schools at Gyeonggi-do. Findings were as follows. First, methods of middle school students getting information related with entering high school turned out in the order of internet search (42.0%), consultation with family and friends (25.5%), consultation with teachers (24.0%). While, their methods of getting information related with entering vocational high school turned out in the order of briefing session by vocational high schools (39.4%), field trip to vocational high schools (24.9%), consultation with teachers from vocational high schools (15.7%). Second, the level of understanding (five points full marks) of Gyeonggi-do middle school students about high school by the type they wished to enter, and the level of information requirement (five points full marks) turned out 3.65 and 3.67 respectively for students who wished to enter general high schools, with the difference being 0.02. On the other hand, the level of understanding and that of information requirement turned out 2.92 and 3.25 respectively with the difference being 0.33, for students who wished to enter vocational high schools. Third, looking at the real state of participation of Gyeonggi-do middle school students in assistance activities for career education provided by vocational high schools, 79.4% of all students were participating. Activity with high participation ratio out of these turned out to be in the order of PR and guide book (booklet, brochure, etc.) for vocational high schools at 90.3%, briefing session prepared by vocational high schools on visit at 87.8% and video of vocational high school PR and introduction at 85.9%. The level of how these activities helped middle school students choose their high school was 3.45, showing more effect by 0.13 on students wishing to enter vocational high schools compared to those wishing to enter general high schools.

The relationship between corporate board attributes and dividend payout is already established yet mediating role of leverage in not been examined in Malaysian market. Therefore, this study aims to examine the mediating effect of financial leverage on the relationship between corporate board attributes and the dividend pay-out policy. A sample of 203 non-financial firms listed on the BURSA Malaysia between 2005 and 2018 were analysed using SmartPLS 3.0. The findings show that there is a partial mediating effect of financial leverage on the relationship between board members age, board diversity and dividend pay-out policy. Financial leverage also mediates the relationship between number of women on board, CEO-duality and dividend pay-out policy. However, financial leverage doesn't mediate the relationship between board size and dividend pay-out policy. This study offers insights to policy-makers to develop a better corporate governance as well as a guidance to firms in the construction and implementation of their corporate governance policies in relation to financial leverage. This study also shed light on the influence of efficient corporate board attributes on dividend pay-out policy and financial leverage for firm growth. This study concludes that corporate board attributes impact capital structure and thus, firms may change its payout policy.

Purpose: This cross-sectional study was designed to identify anger-expression types in late school-age children and investigate the relation between the identified anger-expression types and their health status. Method: One thousand twenty seven children in elementary school fifth and sixth grades were recruited from November to December, 2004. Data was analyzed using descriptive statistics, cluster analysis, 2-test, ANOV A, Duncan's multiple comparison test, and Wilcoxon rank sum test. Results: Three anger-expression types in late school-age children were found; Anger-out/in, Anger-control, and Low anger-expression types. Children frequently using the anger-out/in type among the three types and with a higher state anger reported higher psychosomatic symptoms and depression. Children from a divorced or separated family reported higher state anger. Conclusion: This study suggests that a specific anger management program needs to be developed for late school-age children with high state anger and frequently using the anger out/in expression type. For understanding the anger level and the anger expression types of Korean school-age children, further research needs to be done with large samples using a randomized sampling method.
This study aims to present basic data for preventing drop-out intention by identifying the mechanisms in which academic stress affects drop-out intention through self-esteem, peer relationships, and grit in high school students. The subjects of the study were 283 high school students purposively selected from three cities and counties in Chungcheongnam-do. The data were analysed using SPSS PC+ Win. ver. 25.0 and SPSS PROCESS macro ver. 4.2. The applied statistical techniques were descriptive statistics, reliability analysis, correlation analysis, and moderated mediation effect analysis. As a result of the study, first, academic stress showed a positive correlation with the drop-out intention, but a negative correlation with self-esteem, grit, and peer relationship. Second, grit not only played a moderating role in enhancing the relationship between self-esteem and peer relationship, but also played a moderated mediating role in the path of academic stress → self-esteem → peer relationship → drop-out intention. It was confirmed that the academic stress of high school students has a direct effect on the drop-out intention, and that self-esteem, peer relationships, and grit can be used as important factors to prevent the school drop-out.
purpose of this work was to study the applied effects of out-of-class Chemical Experience Learning (CEL) Programs on scientific process skills and science-related attitude for middle school students. The out-of-class CEL Programs which were developed to make the funny out-of-class chemistry and the exciting science class', included the nature-friendly chemical experiments suitable for natural environment and composed of real life-centered experiences. The out-of-class CEL programs were applied to natural environment through all-day improvement activity. The science club students in D middle school in Busan were selected as the objects of the study consisting of one experiment group and one control group. The out-of-class CEL programs were applied to the experiment group and traditional class method was applied to the control group. The change of scientific process skills and science-related attitudes between two groups were compared and analyzed. And students reaction on the out-of-class CEL programs was investigated. As a result, out-of-class nature-friendly chemical experiments were improved scientific process skills and science-related attitudes of middle school students. Also, more than 70% of students in the experimental group gave positive feedbacks to the out-of-class CEL programs and increased attention, interest, and degree of self-participation in science.
