Using TIMSS survey data, we analyzed whether there were any significant changes in the learning environment of middle school science classes over the last 10 years. Our study selected questions from teachers and school principals' questionnaires and divided them by category: science class, teacher professional development, and school environment. The science class components were subdivided into three categories: science learning activities, evaluation, and homework. Within teacher professional development, the sub-categories included teacher training, collaboration to improve teaching, and teacher evaluation. School environment subdivided into two aspects, these being school characteristics and school system. Our research confirmed that there has been a positive change overall in learning environments. However, most classes are teacher-conducted and also teacher-oriented; the proportion of science investigation activities has declined compared against the prior ten years. Our study show that students do not engage in a range of inquiry-related activities. The questions on tests and examinations involve mostly knowledge application and understanding, although recent methods of evaluation show improvement. As for the science teachers, they participate in many professional development programs but focus on science content, science curriculum, and pedagogy. In addition, teachers do not have many opportunities to participate in the training to integrate information technology into science, science assessment, or improving students' critical thinking or inquiry skills. The teachers are satisfied with their profession, and the shortage of science resources does not seem to affect instruction.

This study was conducted to provide basic data on the relationship between the happiness and job satisfaction of dental hygienists. The research subjects were 264 dental hygienists in Busan and Gyeongsangnam-do. The study was conducted using structured questionnaires and the collected data were analyzed using IBM SPSS software, ver. 20.0. The happiness index, which was based on general characteristics, showed the greatest significant differences in life satisfaction (p<0.05) among adults over 36 years of job experience, negative emotions (p<0.01) among adults under 25 years of job experience, and negative emotions (p<0.05) among adults with 4~10 years of job experience. The factors that improved the job satisfaction of dental hygienists were life satisfaction, prime duty at the work place, and a positive effect. On the contrary, negative emotions lowered the job satisfaction. The happiness of the dental hygienist is an important factor not only for the improvement of the hygienist's personal quality of life, but also the patient's health. It is necessary for dental hygienists to maintain good relationships with coworkers during in the workplace, as well as employers, to have an administrative system that offers proper compensation, improvement of the work environment, and opportunities to improve professionalism at the workplace.

The purpose of this study was to investigate how preservice secondary teacher teaching practice affected future teachers' features, which they should have as teachers. Based on the differences of pre- and post- test of the survey of their teacher competence, the participants of this study were grouped 40 student teachers as the teaching profession, and 58 liberal arts student teachers of learning teaching of 98 students. This study attempted to seek what preservice teachers expected and sought as future teachers throughout the teaching practice in secondary schools. We considered 5 areas of view of teaching profession knowledge and instruction skill, guidance, personality, and general attitude in the teaching profession as an effective teacher competence. The results showed that pre service teachers asserted that the teaching practice provided opportunities to improve their teacher competence as future teachers. However there was significant effective change in the group of student teachers as the teaching profession. This study also suggested that it is necessary to consider the liberal arts student teachers of learning teaching program reflecting the results of this study.

The Solar and Space Environment Division of the Korean Space Science Society investigated the use and possession of ground and satellite observations and models of solar and planetary data operated by domestic research institutes and universities. Based on the findings, we would like to introduce observational instruments, data, and models in solar and interplanetary fields in this paper to improve understanding and use of each data and explore opportunities for interdisciplinary research. The ground and satellite observations, which require a lot of investment, were mainly held by research institutes (National Meteorological Satellite Center, Polar Research Institute, Korean Space Weather, Korea Astronomy and Space Science Institute and KAIST Satellite Research Institute), and model development was overwhelmingly carried out at Kyung Hee University. In solar and interplanetary fields, we introduce Fast Imaging Solar Spectrograph (FISS), neutron monitors, and the analysis models [for the Solar Dynamics Observatory/Atmospheric Imaging Assembly (SDO/AIA) and Hinode/X-Ray Telescope (XRT) observations] in nonequilibrium ionization state as representatives. Survey on solar and interplanetary fields can be downloaded from the website of the Korean Space Science Society (http://ksss.or.kr/). The paper makes know the importance of long-term and continuous management of space science-related materials, and hopes to contribute to enhancing the status of domestic space science data by utilizing locally produced data by various personnel participating in space science research.

SW education was conducted for slow youth learners. 6 learners participatd in 8 sessions of an introductory course using several plays and 3 learners who more interested in introductory course participated in deeper course using normal method. After education, we survey and interview from learners, instructors and heads of welfare organizations. Learners showed interest and participated in the fact that they were participating in SW education, which was widely talked about. Learners were found to be more satisfied with introductory course education using play such as board games, and although they initially appeared to participate in unfamiliar learning content with low efficacy, it was observed that their efficacy increased with repetition. Additionally, it was observed that young people with an IQ of 80 or higher had a higher level of interest or interest in SW education than those with an IQ of 80 or lower. we discussed that there were not many opportunities to directly use the SW education content for youth who are slow learners in work or real life. We suggest this should be a focus education on the use of digital media - online meeting apps, office SW etc.- to improve digital literacy for life and work and that research on this should continue.

This study examined the effects of the demographic and health characteristics and chronic diseases on the health-related quality of life in service employees. From January 1, 2013 to December 31, 2014, this study analyzed the data on 607 service employees based on the 2nd data of the 6th National Health and Nutrition Examination Survey with at-test, ANOVA, and hierarchical regression analysis use of SPSS. The results of the analysis showed that the quality of Life in women was lower (${\beta}=-.074$, p=.050) than that of men, and the older the subjects were, the lower their quality of life(${\beta}=307$, p=.000). Regarding the subjective health status, there was a significant increase in the "very Poor"(${\beta}=186$, p=0.027) and "good"(${\beta}=196$, p=.001) status. The quality of life improved with increasing activity (${\beta}=-0.222$, p=0.000)). Some of the subjects perceived "high stress" (${\beta}=-0.123$, p=0.003) and the others perceived "low stress"(${\beta}=-0.176$, p=0.000). The less they perceived stress, the higher their quality of life. The factors explained 24.6％ of the health-related quality of life of the subjects. Therefore, to improve health-related quality of life of service employees, more activity opportunities should be given, the subjective health status should be positively perceived and psychological measures to decrease the level of stress should be developed.

Throughput scaling laws for two coexisting ad hoc networks with m primary users (PUs) and n secondary users (SUs) randomly distributed in an unit area have been widely studied. Early work showed that the secondary network performs as well as stand-alone networks, namely, the per-node throughput of the secondary networks is ${\Theta}(1/\sqrt{n{\log}n})$. In this paper, we show that by exploiting directional spectrum opportunities in secondary network, the throughput of secondary network can be improved. If the beamwidth of secondary transmitter (TX)'s main lobe is ${\delta}=o(1/{\log}n)$, SUs can achieve a per-node throughput of ${\Theta}(1/\sqrt{n{\log}n})$ for directional transmission and omni reception (DTOR), which is ${\Theta}({\log}n)$ times higher than the throughput with-out directional transmission. On the contrary, if ${\delta}={\omega}(1/{\log}n)$, the throughput gain of SUs is $2{\pi}/{\delta}$ for DTOR compared with the throughput without directional antennas. Similarly, we have derived the throughput for other cases of directional transmission. The connectivity is another critical metric to evaluate the performance of random ad hoc networks. The relation between the number of SUs n and the number of PUs m is assumed to be $n=m^{\beta}$. We show that with the HDP-VDP routing scheme, which is widely employed in the analysis of throughput scaling laws of ad hoc networks, the connectivity of a single SU can be guaranteed when ${\beta}$ > 1, and the connectivity of a single secondary path can be guaranteed when ${\beta}$ > 2. While circumventing routing can improve the connectivity of cognitive radio ad hoc network, we verify that the connectivity of a single SU as well as a single secondary path can be guaranteed when ${\beta}$ > 1. Thus, to achieve the connectivity of secondary networks, the density of SUs should be (asymptotically) bigger than that of PUs.

Daytime activity services based on community care signify 'participatory integrated community care service' fused with diverse forms of community participation and care for adults with developmental disabilities after school graduation. They have the characteristics of lifelong care by life cycle in that adults with developmental disabilities 18 years and older receive daytime care and community participation programs. The purpose of this study is to examine community care based daytime activity services and to search for vitalization plans for daytime activity services that must unfold in the future for care programs that can be meaningful social participation opportunities for adults with developmental disabilities. Through literature review, we analyzed the state of daytime and social activity of adults with developmental disabilities as community care.Based on these findings, we devised ways to improve the daytime activities for the significant daytime of adults with developmental disabilities. At this, it proposed an increase of activity support vouchers, daytime activity service time expansions, expanded budget formulation for an increased number of daytime activity service subjects, expanded applications for the prioritization of the 20% of those with the most severe developmental disabilities and the composition of separate teams, and the role reinforcement of support centers for people with developmental disabilities.

The aim of this study is to verify the relationships of factors affecting nursing performance of clinical nurses focused on positive affective events. The subjects of this study were 275 clinical nurses from secondary and tertiary general hospitals. Data collection was conducted for two months from May 2021 through an online survey through snowball sampling. Data analyzed was using SPSS 26.0 and AMOS 26.0. The variables affecting job satisfaction included direct effect of positive affective events (β=.65, p<.001), and direct effect of positive affectivity (β=.10, p=.038). Job satisfaction (β=.47, p<.001) had statistically significant direct effects on nursing performance. Positive affective events (β=.32, p=.003) and positive affectivity (β=.05, p=.039) had statistically significant indirect effects on nursing performance. These variables explained for 22% of nursing performance. However, emotional labor had no significant effect on job satisfaction and nursing performance. The results indicate that positive affective events and positive affectivity result in high degree of job satisfaction. Job satisfaction would increase the level of nursing performance. Therefore, in order to improve nursing performance, it is necessary to provide educational opportunities and interventions that can promote positive work environment and positive affectivity.

The objective of this study was to improve the sensory qualities of soymilk. For this purpose, soymilk was prepared by adding different types of rice grain, including cooked, puffed, and saccharified rice. Acceptable products could be obtained by addition of saccharified rice. The addition of saccharified rice had a positive influence on sensory qualities, especially mouth feel. Further, soymilk with saccharified rice was comparable in terms of physicochemical characteristics (pH, soluble solids, and viscosity) with commercial whole-bean soymilk. This result suggests that there are opportunities to develop a new market for soy-milk that incorporates health benefits and traditional beverages.
