This study aims to determine the impact of digital literacy skills of middle-aged and older people using public libraries on their life satisfaction. For this study, a survey was conducted on 192 middle-aged and older people aged 40 to 64 living in area G. The collected data were analyzed using the statistical package SPSS 27 program. The analysis methods in this study included frequency analysis, descriptive statistical analysis, t-test, one-way ANOVA, Duncan's multiple range test for post-hoc analysis, and regression analysis. The results of this study are as follows: First, digital literacy competency has a significant positive impact on the life satisfaction of middle-aged and older adults; as their digital literacy skills improve, their life satisfaction increases. Second, digital literacy competency varies based on gender, education level, employment status, and average monthly income, influencing their engagement in activities such as study or work. Additionally, higher levels of digital literacy competency, as determined by the highest level of education, positively affect life satisfaction, leisure activities, and cultural life.

This research was conducted to find out about the effects of a perceived usefulness and a perceived ease of use on the viewer's attitude and their intention to use of the Terrestrial UHD Broadcasting. The survey was conducted with 191 respondents while innovativeness, relative advantage, active engagement, accessibility and affinity were considered as the external variables for this research. As the result shows, the external variables that affect the perceived usefulness are affinity, relative advantage, and innovativeness. However, it was confirmed that the accessibility has no major effect on the perceived usefulness. Among the external variables, the innovativeness has the highest level of effectiveness on the perceived usefulness of UHD broadcasting. Relative advantage, active engagement, and affinity were followed in orderly fashion. Especially, the perceived ease of use on UHD broadcasting has a major effect on the perceived usefulness. Also, the perceived usefulness affects the viewers' attitude and their intention to use. And the research verified that there is no correlation between the perceived ease of use vs. attitude and between attitude vs. intention to use. Therefore, we can safely say that the perceived usefulness of UHD broadcasting has main effects on viewers' attitude and their intention to use of UHD broadcasting.

As a result, the interaction between personal motivation and class type is not significant. On the other hand, the interaction between social motivation and class type is significant and overall online class increases engagement with educational issues. In particular, the group with low social motivation showed greater change than the group with high social motivation, so online education seems to be more effective in the group with low social motivation. It means that by stimulating students' social motivation rather than personal motivation, the effectiveness of online education can be enhanced, and it can lead to education outcomes - behavioral changes and attitudes of learners. In order to revitalize social motivation in the intensely personal space of online, it is necessary to activate social communication methods such as SNS, and development of interpersonal issues and learning materials would be more efficient. In order to derive more specific results, it is necessary to measure the level of prior knowledge and involvement of the participants in class, and to comprehensively investigate and analyze the state of learners before and after class through more variables. Finally, in order to increase the reliability of the research results, it is necessary to clearly prove it through the establishment of a structural model.

The purpose of this study is to examine the differences of perceptions of teachers and students regarding teaching skills. For the analysis, data was collected by ICALT(International Comparative Analysis of Learning and Teaching) class observation tool and students survey called My Teacher Questionnaire. a student survey. The data of teachers and students can be compared because as the two tools have seven common domains(Safe and stimulating learning climate, Efficient organization, Clear and structured instructions, Intensive and activating teaching, Adjusting instructions and learner processing to inter-learner differences, Teaching learning strategies, Learner engagement). In 2016, in Daejeon, Chungbuk and Chungnam. trained teachers collected data from 106 classes, and 2,866 students responded the survey. The reliability and validity of the two tools, class observation and MTQ(My Teacher Questionnaire) are proven to be satisfactory for use in Korean schools. Students perception on teaching was high, particularly when students are in lower grades and learning major subjects like English, Korean, and math. The domain of higher teaching skills, male students show higher perceptions while female students reported higher perceptions on lower-level teaching skill domains. To compare the perceptions of teachers and students, the predictive reliability of students engagement against teaching skill domains was used. Teachers showed higher predictive reliability on lower teaching skill domains while students showed higher predictive reliability on higher teaching skill domains. It is recommended for further study to develop a professional development model using a teacher class observation tool and the My Teacher Questionnaire for pre-service teachers and school teachers.

The purpose of this study was to compare immediate differences in fatigue and motor performance during instrumental playing in patients with chronic stroke depending on whether singing task was concurrently presented. A total of 12 patients with chronic stroke were recruited from community and daycare centers for older adults in Seoul. Six subjects were randomly assigned to the experimental group and six to the comparison group. The experimental group was asked to sing while playing the electronic drum, and the comparison group only played the drum. The results of this study showed that statistically significant differences in perceived fatigue and exertion were found between the two groups, while no significant group differences were found in level of engagement in playing or force of tapping during drum playing. This study supports the inclusion of a singing task in instrument playing rehabilitation to effectively decrease perceived fatigue and level of intensity of exercises, although this may not lead to immediate changes in motor function or level of target exercises. The results indicate that singing while instrument playing may help stroke patients shift their attention from the executed motor movements to singing and alleviate the attentional and emotional load from intense movements. This study presents implications for how to select and pattern target movements in music therapy intervention for better motor outcomes.

By analyzing a nationwide survey on Korean publics, this study examines the social determinants of public support for three types of scientific research-basic research aimed at pure knowledge, applied research toward industrial application, and research for social problem-solving which aims to enhance ordinary citizens' quality of life. The present study finds the differential effects of social- and political value orientations on the level of public support for respective types of research. As ones have more progressive in their subjective political orientations, they are more likely to support research for social problem-solving than other types of research, while conservatives tend to support basic research and those with neo-liberal ideology tend to support applied research. The Korean public also tends to perceive research for social problem-solving as a counter to basic research while it has been developed against the conventional emphasis on applied research in Korea. Also, the level of support for research for social problem-solving increases with the higher level of trust in scientific authority and expertise, while it has been developed against expertism and included public engagement in science as an important element. Finally, those who have lower income tend to support for research for social problem-solving than other types of research. The implications of these findings are discussed.

The purpose of this study is to compare voice characteristics and voice-related quality of life (K-VRQOL) of the elderly female choir members using perceptual-auditory voice quality evaluation (GRBAS) and K-VRQOL scales. The participants were 77 women over 60 years old who were actively engaged in the choir in either Seoul or Busan. There are two kinds of choirs that indicate different engagement levels: regular choir and church choir. The perceptual-auditory vocal quality evaluation was listened to by / a / vowels and were graded by experts using the GRBAS scale. As a result, when comparing the differences between groups, the elderly female participants of the regular choir showed higher satisfaction in speech using the subjective speech recognition level than the elderly female members who performed in the church choir. In addition, the analysis showed that the satisfaction level was high in the physical function area of the K-VRQOL scale. This study confirmed that choral activities could yield positive results not only in terms of improving voice function in old age, but also to improve the subjective perception level of voice use, thus suggesting the necessity of systematic music programs to improve voices that are aging.

The Russo-Japanese War(1904-1905) in the early 20th century greatly influenced the international politics in Northeast Asia and the destiny of both countries. There are many studies on the cause of the outbreak and its effect on the Korean peninsula. The victory and defeat of the battle of Tsushima also the subject of research by renowned scholars and navy officers. Many previous studies have analyzed the process of engagement. However, There was a lack of research that analyzed at the tactical level of naval commanders. Therefore, this study tries to review the battle of Tsushima in terms of tactical level, that is formation, maneuvering, damage control. Naval operations at sea with many variables are not always done as planned. The intuitive judgement and readiness have had a decisive impact on victory and defeat. The analysis of the naval warfare on the basis of formation, maneuvering, and damage control makes the cause of the win more clearly. The conclusion of the this study can be summarized in five ways. First, victory would be achieved through the suppression of the beginning. The destiny of the Tsushima battle was determined by an 1 hour after first firing. The Japanese fleet caught fire by paralyzing the command and control capabilities of the Russian fleet. Second, the Japanese fleet's power was superior to the Russian fleet. In general, Japan and Russia had similar powers, and Admiral Togo's "T crossing tactics" decisively contributed the victory. However, when compared to the weapon system level, formation and maneuvering, Japan was much more dominant. Third, people realized that one side to be annihilated in the battle between similar powers after the Tsushima battle. The common perception before the Battle of Tsushima was that the battle ship would not sunken, and that the result of wiping out was difficult. However, there is s time for one sided victory and defeat depending on the early suppression nad the destruction of the command and control ability. Fourth, it is the importance of damage control ability. The main cause of the Russian fleet's loss of command and control ability was thick smoke from fire, and maneuverability was greatly deteriorated due to coal overload. In this way, importance is still valid after more than 100 tears. Fifth, the area of uncertainty. In the navy battles, one or two shots of clear firing in the beginning and small misconception and minor mistakes decide win or loss. Ultimately, this area of fortune can be linked to mindset of the commander. I hope this research will be help to naval researchers and naval commanders at the sea.

This study analyzes the epistemic considerations and the argumentation level revealed in the discourse of the key concept of natural selection for science-gifted elementary students. The paper analyzes and discusses the results of a three-student focus group, drawn from a cohort of twenty gifted sixth-grade elementary students. Nature, generality, justification, and audience were used to analyze epistemic consideration. Learning progression in scientific argumentation including argument construction and critique was used to analyze students' scientific argumentation level. The findings are as follows: First, Epistemic considerations in discourse varied between key concepts of natural selection discussed. The nature aspect of epistemic considerations is highly expressed in the discourse for all natural selection key concepts. But the level of generality, justification and audience was high or low, and the level was not revealed in the discourse. In the heredity of variation, which is highly expressed in terms of generality of knowledge, the linkage with various phenomena against the acquired character generated a variety of ideas. These ideas were used to facilitate engagement in argumentation, so that all three students showed the level of argumentation of suggestions of counter-critique. Second, students tried to explain the process of speciation by using concepts that were high in practical epistemic considerations level when explaining the concept of speciation, which is the final natural selection key concept. Conversely, the concept of low level of epistemic considerations was not included as an explanation factor. The results of this study suggest that students need to analyze specific factors to understand why epistemological decisions are made by students and how epistemological resources are used according to context through various epistemological resources. Analysis of various factors influencing epistemological decisions can be a mediator of the instructor who can improve the quality and level of the argumentation.

Although healthy lifestyles have been proved as an effective way of improving higher well-beings for individuals. researches on health-promoting behaviors of minority elderly with a specific ethnic heritage have been sparsely tried. This study was designed to explore health-promoting lifestyle patterns of Korean immigrant elderly living in Seattle, USA and its relationships with two associated perceptual variables, self-esteem and perceived health status. One hundred ten Korean immigrant elderly were recruited from two senior centers and interviewed with a structured questionnaire. Data were collected from October 1998 to January 1999, and analyzed using SPSS program through which t-test, ANOVA, and Pearson Correlation Coefficients were tested. As the results, the mean HPLP score of the Korean immigrant elderly was 2.54 (SD ＝ .36), showing significant differences by education (F ＝ 3.61, P ＝ .016), economic status (F ＝ 3.01, P ＝ .034), and current health status (F ＝ 3.69, p ＝ .008). In self-esteem, two socioeconomic variables showed statistical association with self-esteem : marital status (t ＝ 2.47, P ＝ .015) and living situation (F ＝ 4.03, p ＝ .021). The HPLP subscales that showed higher mean scores were nutrition (M ＝ 3.01, SD ＝ .52) and interpersonal support (M ＝ 2.65, SD ＝ .47) while lower mean scores were detected in the domain of exercise (M ＝ 1.92, SD ＝ .74) and stress management (M ＝ 2.26, SD ＝ .47). Perceived health status revealed significant positive correlation with health-promoting lifestyle patterns (r ＝ .19, P ＝ .043) and self-esteem (r ＝ .32, P ＝ .001) in the present study. It is concluded that engagement in health-promoting lifestyle patterns should be actively encouraged to enhance personal health of Korean immigrant elderly. Developing health promotion programs focused on exercise and stress management is also imperatively suggested not only for better health practices of Korean immigrant elderly population but also for enhancing their level of well-beings and life satisfaction.
