This study examined the relationship between depression, anxiety, stress, and adaptation to college life of international students living in South Korea during the COVID-19 pandemic and the factors affecting the adaptation to college life. This study was carried out between December 3, 2021, to January 25, 2022, on international students living in South Korea. The questionnaires were composed of self-reported questionnaires, and the survey URL was sent as text messages to international students who understood the purpose and rationale of this study and consented to participate in the survey. The data were analyzed using SPSS WIN 22.0, and t-test, ANOVA, Pearson's Correlation Coefficient, and hierarchical regression were performed. As a result of the study, the average score of the study subjects was 8.44 points for depression, 8.28 points for anxiety, and 9. 28 points for stress. factors with significant differences in adaptation to college life according to general characteristics were living means and smoking. The relationship between the main variables, it was significant with depression (r=-.785, p<.001), anxiety (r=-.593, p<.001), and stress (r=-.726, p<.001). There was one negative correlation. It was found that the higher the depression, anxiety, and stress, the lower the college life adaptation. Lastly, depression (β=-.666, p<.001) was the factor affecting foreign students' adaptation to college life, and the explanatory power was 62%. Therefore, for international students to adapt to college life, it is necessary to establish an institutional strategy to detect depression, a negative psychological emotion, at an early stage and to systematically manage it. Also, it is necessary to find an intervention plan to relieve depression that can be applied in social isolation situations due to the spread of infectious diseases. Research confirming the intervention effect should be upgraded.

This study investigates income support, labor opportunities, and social capital by the demographic characteristics of the elderly who participate in the elderly job project, and especially the relationship between social and quality of life. We want to provide empirical data on how the elderly vocational business ultimately affects the lives of the elderly through the intervention of social capital. The intervention effect of social capital is as follows. Satisfaction with the elderly job project has a great impact on the quality of life, trust, network, and social participation. In particular, trust in the quality of life of the elderly had a great influence on the quality of life and was indirectly effective. In addition, the intervention of social participation between social capital was known, and the elderly job project increased social participation to improve the quality of life of the elderly. Therefore, it can be evaluated that the elderly job project has an important positive effect on the quality of life of the elderly, and the social capital formed through the elderly job project plays a role in directly or indirectly improving the quality of life of the elderly.

This study attempts to provide basic data for the development of manpower maintenance programs by checking the degree of job stress and emotional burnout for nurses working in a university hospital and identifying factors affecting emotional burnout. Data were obtained through a structured questionnaire survey conducted on 187 nurses. The average score for job stress of nurses was 2.50 (range 1 to 4) and emotional burnout was 3.29 (range 1 to 5). The factors affecting emotional burnout were occupational climate, job demand, job insecurity, and lack of reward, which accounted for 44% of explanatory power. In order to reduce the emotional burnout of nurses, the management of medical institutions needs administrative and financial support. Further, it is necessary to improve the organizational culture regarding job assignment through job analysis, employment security, and a performance-based reward system.

This study analyzes the impact of occupational accidents on economic growth and labor productivty losses in Korea between January 2008 and July 2018, using the Vector Error-Correction Model (VECM). According to the analysis, the occurrence of occupational accidents was revealed to reduce the number of employed workers and also hinder economic growth. This can be reinterpreted as the reduction of occupational accidents does not cause labor losses in the industry, rather may induce economic growth. Also, the findings discovered that an increase in the number of workers may lead to increase in the probability of occupational accidents in the short term. This suggests that greater number of work-related accidents may occur during the early stages- due to new employees' lack of knowledge related to safety at workplace.

Gyeongsangnam-do needed an employment stability response policy to induce re-employment of job seekers who retired due to large-scale unemployment and job instability following the employment crisis, and stable settlement and long-term employment after new employment.This study is to confirm the effective corporate support policy as an employment promotion strategy through new recruitment of the employment crisis in Gyeongsangnam-do. A total of 380 companies in Gyeongsangnam-do were targeted for the survey through online surveys and in-person surveys. As a result of the study, as a measure to improve working conditions through financial support for long-term employment stability, first, support for youth-middle-age asset formation of SME workers is required, and second, support for old-age income guarantee for SME workers was proposed. Third, direct corporate subsidies are continuously needed for job promotion and job stability of Gyeongsangnam-do companies.

This study is an attempted content analysis study to analyze recent studies on clinical practice of nursing college students to identify problems with clinical practice and provide evidence for desirable clinical practice. For data collection, a total of 14 papers published in academic journals between 2017 and 2021 were selected. The analysis method was performed according to the systematic review reporting guidelines presented by Cochrane Collaboration and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) group. As a result of the analysis, two themes, Four sub-themes, and seventeen concepts were derived, and the clinical practice study of nursing college students showed the necessity of standardized clinical practice protocol regulations for nursing college students and respect for patient human rights. Based on the above research results, it is proposed to prepare a nursing and clinical practice protocol that can clearly present the role of nursing college students during clinical practice.

The purpose of this study is investigate the effects of quality of life and occupational performance on quality of sleep in college students. Data had been collected from Sep. 1 to Sep. 30, 2021. The subjects of this study were students majoring in occupational therapy at C College situated in C region. For analysis, 103 copies of questionnaire were used. As study instruments, a structured questionnaire incorporating questions about general characteristics, and measurement scales for quality of life, quality of sleep, and occupational performance evaluation were applied. Subjective sleep quality and sleep latency of study participants had lower scores than other components. According to the analysis on different quality of sleep depending on general characteristics, women had more sleep disturbances as they didn't have any part-time job. In terms of the correlation between quality of sleep and quality of life, physical health and total score (quality of life) had correlations with daytime dysfunction. With regard to influential factors on quality of sleep, rest & sleep as a domain of occupational performance and work affected quality of sleep. Students' quality of sleep will be improved if they keep regular habits of living, have rest appropriately for alleviating their stress, and do their jobs with interest and successfully according to a procedure. It is expected that the results of this study will be helpful to care for the health of would-be experts in charge of national health care.

This paper is intended to study the tragedy of Kim Sung-han's short stories 'Extreme' and 'Return'. The author describes the postwar chaotic reality as a tragic reality in the novel as the pain of the times people experience.

This study is to investigate that population change as a result of the decline in population has a correlation with a decrease in crime, with the change in the demographic composition by comparing with two models: model with growth in population and one with the decline in population. We collected demographic data for all cities in Korea from the 2010 Census to 2020 offered by the Korean Statistical Information Service, with crime data comprising serious reported crime events from the Korean Nation Police Agency through requesting data related to the total number of crimes at the same as the period of demographic data. This study can identify the impacts of demographic changes as a result of population change on crime change through a comparative analysis between areas with population growth and ones with population decline. We can confirm that there are differences in determinants of crime between areas with population increase and one with population decrease from the analysis of the impact of demographic change as a result of population change on crime change.

The purpose of this research is to investigate the types of semantic errors made by MT in translating EFL college students' original drafts written in Korean into English. Specifically, this study attempts to find out 1) what types of semantic errors are most frequently committed by MT? and 2) how students feel about the quality of the MT-produced output? The findings from this study indicated that MT produced the errors related to accuracy (47%) the most, followed by the errors related to fluency and ambiguity (14.6% respectively). Students were well aware of the errors with accuracy and fluency but had limited ability to check the errors with ambiguity. Based on the findings, this study suggests pedagogical implications which can be implemented in L2 writing classrooms.

This study focused on the spirit to becoming the true "I" as a human, and it attempted to pay attention to the "images" sent by the unconscious to prompt the reality of that spirit. The purpose of this study was to identify the symbols in myths and folk tales that appeared in the individual's dreams and to shed light on how the universal experiences of humankind are re-experienced and integrated into an individual's life. This study used a total of 105 mandala paintings collected through the researcher's own dreams from February 2019 to September 2020. Among them, repeated symbols were classified into basic shapes, squares, crosses, triangles, circles, and spirals, as suggested by Riedel. The study truthfully described the discovery of a practical layer of psychology as a human's individualization and changing, resulting in autoethnography, which is a type of qualitative study.

In previous private education expenses were concentrated only on expenses for elementary, middle, and high school students. Therefore, it is difficult to understand the actual condition of preschool children's private education expenses. To solve this problem, we analyze the 2013 and 2020 data of the Korea Welfare Panel to confirm the private education expenditures of pre-school children. Also, we examine the differences and changes in private education expenditures according to household variables. We selected the household variable as the socio-demographic variable of the study subject. We defined the household variable as the area and income of the household. We show the actual results of private education expenses for household variables using frequency analysis, descriptive statistical analysis, t-test, and one-way ANOVA of SPSS 27.

The purpose of this study is to empirically analyze the mediating effect of innovation activities on the effect of organizational culture perceived by organizational members on organizational effectiveness. The main results are as follows. First, Hypothesis 1, organizational culture, was adopted as it showed a positive influence on innovation activities. Second, since organizational culture showed statistically significant effect on organizational effectiveness, Hypothesis 2 was adopted. Third, the innovation activity, which is hypothesis 3, was analyzed to have a positive influence on organizational effectiveness. Therefore, hypothesis 3 was accepted. Fourth, the innovation activity, hypothesis 4, showed a mediating effect between organizational culture and organizational effectiveness. As shown in the results of this study, it is indicated that organizations should improve organizational effectiveness for growth and development through the advancement of the sustainability management system in the rapidly changing business environment. To this end, it was necessary to systematically build and activate an organizational culture and innovation activities suitable for the characteristics of the organization. In other words, organizational effectiveness can be improved when constructing and implementing advanced innovation activities based on measures to revitalize organizational culture according to changes in the business environment.

This paper aims to analyze discourse metaphors by paying attention to Seoul mayoral by-election, mainly focusing on election campaign and its related news articles. The 2021 Seoul mayoral by-election was held because the former mayor died in an apparent suicide after he was accused of years of sexual harassment to a former secretary. But in the run-up to the by-election, the newly coined word 'alleged victim' from the ruling party caused a big controversy because the party attempted to deny the authenticity of the secretary's claim by calling her "an alleged victim," instead of "a victim" to defend the former mayor who is a member of the ruling party, implying that the woman's claim is just an allegation with no proof. Thus, this paper has analyzed how news stories were reported with regard to the word 'alleged victim' poser on news stories in two Korean quality newspapers, a conservative newspaper (Chosun Ilbo) and a liberal newspaper (Hankyoreh) from March 1 to April 1, 2021 and analyzed them with the framework of Lakoff and Johnson's Conceptual Metaphor Theory(1980). The findings are as follows: (i) the conservative newspaper reports this issue much more than the liberal newspaper; (ii) both quality newspapers follow the metaphor principles by Conceptual Metaphor Theory; (iii) the conservative newspaper is more likely to follow the Strick Father model (a conservative model) while the liberal newspaper is to follow the Nurturant Parent model (a liberal model), thus indicating that each newspaper's ideology is well represented by the models of Conceptual Metaphor Theory

Boredom is considered anxiety and is an experience accompanied by a lack of meaning because the need for meaning is not met. It is the pain that people feel without using their mind, and the suffering that people fall into the absence of desire. On the other hand, religious activities give people meaning in life, which reduces the tendency to feel bored. This study investigates whether there is a difference in boredom depending on whether individuals participate in religious activities, and to verify whether the meaning in life mediates the relationships between religious activities and boredom. We predicted that if individuals engaged in religious activities, the meaning in life would increase, and they would be less bored than those who did not. A total of 82 college students participated in this study. Results showed that there were significant differences in the meaning in life and boredom between the two groups according to whether they participated in religious activities or not. The group actively participating in religious activities had significantly higher meaning in life and lower boredom than the non-religious group. Second, the meaning in life significantly mediated the relationship between religious activities and boredom. We conclude that active participation in religious activities can increase the meaning in life and ultimately reduce boredom. Based on the results of this study, the implications and suggestions for follow-up studies are discussed.

As part of the police reform, the current government is trying to establish a police bureau under the Ministry of Public Administration and Security and improve the personnel management of the police. Like the prosecution bureau under the Ministry of Justice, the main goal of the police is to establish a police support bureau in the Ministry of Public Administration and Security to have personnel, budget, disciplinary action, and inspection. However, the government's control of police rights was opposed mainly by the "Police Workplace Council," which is like a police union, and even police officials agreed with it, and the opposition was severe. It is becoming a form of struggle between the government and police organizations. As a police major, I don't want to side with anyone and support the police. However, I thought about what democratic control of the police should be with, considered what the police reform plan is, and analyzed the legal and institutional aspects of the current police, and expressed the following issues. First, this paper is as follows: First, we considered what the democratic control of the police was. Second, We focused on reform measures such as the personnel system and institutional approach. Third, I presented my argument on what the police reform plan is.

Vaccine diplomacy is a manifestation of competition for political influence among great powers amidst the Covid-19 pandemic's blatant illustration of ineluctable interdependency across the global community. The reinforcement of trends bolstering global polity construction intensify concomitantly with nationalist populist value and attitude expressions increasing political polarization. The interdependency graphically illustrated in the Cold War-era's mutual assured destruction incentivized competition into indirect competitive intervention in the internal politics of third actors. Indirect international influence contestations included extended, de facto challenge competitions to generate soft power on behalf of the victor, e.g., the space race. The Covid-19 pandemic has intensified this competition to offer alternative development models while intense domestic political polarization undermines the mobilizational capacities for achieving sustainable development. In contrast to multinational and multiethnic states, nation states have an inherent mobilizational advantage because of the enhanced control capabilities available to the authorities without emphasizing coercion. Control through Gramscian hegemonic mechanisms is more readily feasible in nation states through the greater feasibility of commodification of social relations by states authorities regulating and channeling social competition to encourage social mobility and creativity. The regulation of the so-called private sector serves to manage and contain social competition while channeling it to develop the institutional capacities for control and allocation of developing societal human resources. It enhances developed state control mechanisms and international influence capacities. The appeal of offers of aid and assistance to the so-called developing world becomes ever more urgent amidst Anthropocene crises including its most recent, current Covid-19 pandemic disaster.

The purpose of this study is to investigate the recyclability of Shenlong in China using SWOT. The main analysis results are as follows. First, provided that the company's current capacity utilization rate is seriously insufficient, reducing staff is one among the effective ways. Second, Shenlong should open a web store to cater to young people's online shopping behavior, and further expand the brand visibility using national mainstream media and online shopping platforms like Taobao and JingDong to market Dongfeng Peugeot and Dongfeng Citroen on the whole network. Third, under the premise of maintaining the present best-selling models, Shenlong should appropriately reduce the amount of models, adjust the assembly capacity ratio of every model and every displacement in real time per the newest market trends, increase the agility of auto companies' production, and timely meet the wants of domestic consumers. Fourth, dual-brand coordination and channel integration are very necessary, and also the profitability and profitability of dealers are going to be further improved, thereby increasing sales. Fifth, target building new energy leading products of Shenlong, strive to attain the forefront of the industry within the sales of recent energy vehicles within 5 years, and gradually expand new energy vehicle products from passenger vehicles to passenger vehicles and commercial vehicles. Finally, the marketing field of Shenlong Automobile should achieve "three major changes", that is, change from a goal-driven type to a demand-driven type, cancel the bundling of outlet invoicing goals and delivery incentive tiers; start from basic capabilities, and set pragmatic and challenging goals; focus Channels, to realize following the activation of outlets, and single store sales increase.

Social services are divided into care services and other support services for the elderly, children and the disabled. These social services are the subject of great policy interest in that they can create two effects at the same time: increase in labor demand for service providers and increase the possibility of long-term accumulation of human capital for service recipients. Therefore, this study aims to confirm the hypothesis according to whether the use of social services affects family relationships and the effects of social service users' psychological adaptation on marital and parent-child relationships even when other related variables are controlled. The final result of this thesis is a regression analysis to find out the effect of psychological adaptation on the family relationship, spouse relationship, and relationship with children of subjects who have experience using social services. -.661, p=0.001), the higher the psychological adaptation, the higher the spouse satisfaction (β=.465, p=0.001) and relationship satisfaction with children (β=.360, p=0.001). In other words, it was found that the more depressed the psychologically, the more negative the relationship with spouse and children.

This study aimed to explore the themes and parameters of environmental health behaviors based on Rogers' protection motivation theory through a systematic mapping review. Using a systematic approach, a literature review was conducted of articles that adopted Rogers' protection motivation theory. A total of 11 articles on protection motivation theory using participants and environmental health as outcomes were identified in a search of CINAHL, Cochrane Library, EMBASE, Eric, PsycARTICLES, PubMed, and RISS between September 1 and September 8, 2021. Themes related to the environment and personal behaviors between 2002 and 2021 were extracted. The parameters based on protection motivation theory were identified through systematic mapping as fear appraisal, rewards of maladaptive response, severity, vulnerability, costs of adaptive response, response efficacy, self-efficacy, and intention. Self-efficacy and response efficacy considerably affected environmental health behaviors. Emotional fear appeal related to environmental hazards motivates an internal process that alters the threat appraisal and their coping appraisal. Environmental behavior perception and intention influenced on environmental health behaviors with small effect sizes. Therefore, a deeper understanding of the severity of environmental health issues could lead to the development of helpful, effective, and intensive interventions to promote healthcare among the vulnerable population.

The abstract should summarize the contents of the paper and written below the author information. Use the word "Abstract" as the title, in 12-point Times New Roman, boldface type, italicized, centered relative to the column, initially capitalized, fixed-spacing at 13 pt., 12 pt. spacing before the text and 6 pt. after. The abstract content is to be in 11-point, italicized, single spaced type. Leave one blank line after the abstract, and then begin the keywords. All manuscripts must be in English. When it comes to the issue of "virtual and real" in traditional Chinese painting, the first impression is to describe the problems of painting strokes and ink, layout of pictures, etc., but it runs through the initial conception of the work, creation in the middle and aesthetic appreciation of the work. It exists in the whole process of artistic creation and appreciation. In essence, it is a problem of aesthetic thinking and philosophical thinking. Because the traditional Chinese painting theory is influenced by Taoism, when the concept of "virtual and real" is implemented in the specific picture of Chinese painting, it is contained in the specific shape of "physics", that is, the painting theory research of "blank space" in the picture. Based on the traditional Taoist philosophy of China, this paper takes the "virtual and real" view in Lao Zhuang's thought as the research object, deeply analyzes and compares its relationship with the "virtual and real" in Chinese landscape painting, and finds out their artistic spirit, essential characteristics and how to present them. This paper mainly discusses the internal relationship between Taoist philosophy and "virtual and real" in Chinese landscape painting from the following aspects. The introduction expounds the origin, purpose, significance, innovation and research methods of the topic. This paper analyzes the philosophical thoughts about landscape in the philosophical thoughts represented by Lao Tzu and Zhuangzi. The development of Chinese traditional aesthetics theory is closely related to Taoist philosophy, which has laid the foundation and pointed out the direction for the development of Chinese painting theory since ancient times. It also discusses the influence of the Taoist philosophy of "the combination of the virtual and real" on the emergence and development of the artistic conception of landscape painting. Firstly, through the analysis of the artistic conception of landscape painting and its constituent factors, it is pointed out that the artistic conception is affected by the personality and the painting artistic conception. Secondly, through the Taoist thought of "the combination of the virtual and real" in landscape painting, so as to reflect that it is the source of the artistic conception of Chinese landscape painting. It is the unique spiritual concept of "Yin and Yang" and "virtual and real" that creates the unique "blank space" aesthetic realm of Chinese painting in the composition of the picture. Finally, it focuses on the "nothingness" in Taoist philosophy and the "blank space" in Chinese landscape painting. The connotation of the "blank space" in Chinese painting exceeds its own expressive significance, which makes the picture form the aesthetic principle of emotional blending, virtual and real combination and dynamic and static integration. Through the "blank space", it deepens the artistic characteristics of the picture and sublimates the expression of "form" in Chinese painting.

Unity Painting is a concept that the researcher put forward to locate his own creative style in his creation. Unity Painting, with a clue of reflecting the characteristics of contemporary oriental visual culture, combines the contemporary painting features of a variety of western painting languages. It aims to link the painting system formed in the context of oriental culture with the world's contemporary art and try to present a new contemporary painting with oriental genes. According to the Chinese literature, the researcher sorted out the five main colors (五正色), ten colors for Heavenly Stems (十天干色彩), five intermediate colors (五间色), and five colors as the expression of the Chi of Thriving and Fading and the Chi of Birth and Death, and deduced the summary and stipulation of the color of yin-yang and five elements under the concept of Unity Painting. Based on this, the researcher drew the color-phase and its variation stipulation diagram of ten colors for Heavenly Stems, the orientation of Heavenly Stems (天干方位), color-phase variation diagram (色相变化图), as well as the stipulation system diagram of the five elements (五行), Heavenly Stems and Earthly Branches (干支), energy, time and colors. Through the research and collation of the literature, the researcher took the stipulated five elements color (五行色彩) as the basis of the color concept of creation to complete the work. This paper discusses how to find the starting point of contemporary art creation in the context of traditional oriental culture, sorts out the practical creation logic, and provides ideas for subsequent researchers, with a view to better establishing the identity of the creator and providing research significance and value in the context of the study of oriental art.

The Han Dynasty was the great unification dynasty in history after the Qin Dynasty. Since the Han Dynasty inherited the Qin system, the seal script of the Han Dynasty developed continuously based on inheriting the Qin Small Seal Script. With the progress of social productivity, the Official Script gradually replaced the Seal Script in the Han Dynasty, but the Seal Script did not disappear completely; instead, a special line of development arose under the influence of the Official Script. Through the study of seal script of Han Dynasty inscriptions, this paper understands that the practical function of seal script of inscriptions has been weakening under the influence of clerical script, but the aesthetic value has been increasing day by day. Moreover, there were new artistic innovations in the context of the development of the diversification of inscriptional forms, and its emphasis on social role, cultural status, and the presentation of an aesthetic style that had a profound impact on later generations are worth studying.

This study investigates the association between corporate international diversification and audit fees and audit hours. Korean firms' overseas investment has rapidly increased in recent years and the trend of international diversification is expected to accelerate in the future. Thus, it is important to investigate how auditors respond to globally diversified firms. Our empirical findings show that internationally diversified firms incur higher audit fees and audit hours. This suggests that auditors perceive global diversification as being a higher business risk and require higher external audit fees so that they can decrease audit risk arising from inherent organizational complexity. Further, auditors expand audit procedures to collect more audit evidences, exerting increased audit effort. This study provides empirical evidences that corporate global diversification results in higher audit fees and audit hours. Auditors may refer to these results when planning their audit and determining audit fees and audit hours.

Psychiatric nursing is a specialty where nursing students experience many difficulties in applying what they have learned in theory to clinical practice. Therefore, a situation-oriented case-based strategy is required to help them overcome the limitations of psychiatric nursing clinical practice and reduce their burden. This study aimed to measure the effectiveness of a psychiatric nursing clinical practice program using situation-oriented case-based learning. Participants comprised 63 nursing students in psychiatric nursing classes. The students were asked to create a scenario of interaction between a nurse and patient based on a case study. Empathy, therapeutic communication ability, and attitudes toward mental illnesses were measured. We analyzed the effectiveness of the program by comparing changes in the nursing students' empathy, therapeutic communication ability, and attitude toward mental illness after the program. The participants showed significant increases in empathy and therapeutic communication abilities. However, there were no significant changes in attitudes toward mental illnesses. Based on the results of this study, it is expected that situation-based learning will be effective for students who have difficulties in certain aspects, such as COVID-19, or where there are limited clinical practice opportunities, such as psychiatric nursing.

The purpose of this study is to develop an e-teaching portfolio to perform a teaching portfolio of an instructor on the web. I order to carry out this study, an initial model of the e-teaching portfolio was developed through systematic literature review, and the final e-teaching portfolio was developed by selecting and applying five students, then modifying and supplementing them. The study period was from May 1 to May 20, 2022. As a result of the study, the components of the finally developed e-teaching portfolio are Step 1: Understanding oneself, Step 2: Goal setting, Step 3: Learning strategy, Step 4: Self-check. In conclusion, the program developed through this study is a convenient function that can process everything in one place by connecting the fragmented teaching results, and the developed e-teaching portfolio can promote interaction between individuals by building a community. It has possible characteristics. In order to systematically activate the e-teaching portfolio developed through this study, it is necessary to establish an online management system for systematic operation. Furthermore, an institutional device is needed to guarantee the result of the developed e-teaching portfolio. In order to continuously manage the quality of the teaching portfolio, extrinsic rewards that stimulate the instructor's intrinsic motivation should be provided.

We compared and analyzed the changes in students' science grades and their effects on science grades by level (upper, middle, and lower) according to non-face-to-face and face-to-face teaching-learning. 66 students from A Middle School in Gyeongsangnam-do were selected for the study. As a result of analyzing the change in science grades according to the teaching-learning type, the average score of science grades by non-face-to-face teaching-learning was lower than the corresponding score of science grades of face-to-face teaching-learning. As a result of comparing the level of understanding of learning content according to the evaluation type (paper-written, study-paper) in non-face-to-face and face-to-face teaching-learning, the average scores of science grades by paper-written and study-paper evaluations in non-face-to-face teaching-learning were significantly low. In addition, as a result of comparing the effect on science grades by level according to the teaching-learning type, the average score of science grades of lower-ranked students in non-face-to-face teaching-learning was relatively low.

This study intends to examine gender differences in predictors of Human Papilloma Virus (HPV) vaccination intention based on the Theory of Planned Behavior (TPB). Specifically, this study investigated whether the variables constituting TPB might show differential effects on college men and women's HPV vaccination intention. The current study also examined which specific subjective norms are more influential in explaining HPV vaccination intention of men and women. The results of an online survey revealed that females showed significantly higher intention to get the HPV vaccine and perceived behavioral control than male students. Female students' vaccination intention was best predicted by perceived behavioral control whereas friend norm was the most influential predictor of male students' intention to get the HPV vaccine. The results of this study provide implications for persuasive strategies required to appeal to college men and women to increase HPV vaccination rate.

In order to find out the factors influencing students' willingness to continue exercise and increase their willingness to continue exercise, I conducted an investigation on Chinese college students' motivation to exercise and to improve their healthy lifestyle. Through a questionnaire survey of 312 Chinese university students, the motivation of sports participation, the promotion of healthy lifestyle and the willingness to continue exercise were measured. The questionnaire data were collected from November 2021 to January 2022. The questionnaires were collected and processed by SPSS, and the analysis methods were frequency analysis, reliability analysis and linear regression analysis. The results show that there is a significant relationship between the motivation of exercise and the healthy lifestyle of Chinese college students and the persistence intention, and the limitations of this study and suggestions for future research are discussed.

During last few years, pandemic of COVID-19 has been a global issue. Under the COVID-19, global events have been restricted or canceled to secure public hygiene and safety. Since one of the largest global events is Olympic Games, we selected recent Olympic Games as our case of analysis. Tokyo Olympic Games (TOG) was held in 2021, but it encountered a millennium disaster, the pandemic of COVID-19. In such a special period, it is of great significance to explore the emotional tendency of global views before and TOG via artificial intelligence. This paper vastly collects the TOG comment data of mainstream websites in South Korea, China, and the United States by implementing crawler program for sentiment analysis (SA). And we use a variety of sentiment analysis models to compare the accuracy of the experimental results, to obtain more reliable SA results. In addition, in the prediction results, to reduce the distortion of opinion by a minority, we introduce an algorithm called "Removing Biased Minority Opinions (RBMO)" and provide how to apply this method to the interpretation domain. Through our method, more authoritative SA results were obtained, which in turn provided a basis for predicting the sentiment tendency of countries around the world in TOG during the COVID-19 epidemic.

In this study, design of an intuitive internal resistance diagnostic device is to diagnose the residual capacity and aging of the battery regardless of the model and the internal protocol of the waste battery through the method of measuring the internal resistance of a waste battery. In this paper, charging and discharging were continuously performed with 2A charging and 5A discharging in order to secure data on impedance changes that may occur in the charging and discharging process of various methods. As a result of the final experiment, it was confirmed that the impedance change occurred during charging and discharging, and the amount of change increased as the charging/discharging C-rate increased. In addition, it was confirmed that the waste battery aged or abnormal cell had a large change in the impedance value.

This paper examines the change and its meaning of marketing strategy in business administration, which is changing along with the development of digital technology. Unlike conventional marketing, digital marketing is creating new relationships and making changes through a two-way approach rather than a one-way approach between producers and consumers. And these changes are creating new approaches not only in the problems between businesses and consumers, but also in the relationship between public institutions and citizens. In particular, the potential of platforms, which are emerging as important in digital management, is applied to public policies, and efforts are being made to establish marketing strategies for public institutions. One case of this was applied to the cultural contents industry and policy to examine specific measures and visions. The cultural big data platform is in line with digital management and continuously utilizes digital marketing strategies in the public domain, and aims to promote creative work as well as publicize it to citizens and workers in the cultural content industry. The synergy effect that will emerge from the combination of the cultural big data platform and digital management is expected to continue.

The NOx removal performance of the SCR process depends on various factors such as catalytic factors (catalyst composition, shape, space velocity, etc.), temperature and flow rate distribution of the exhaust gas. Among them, the uniformity of the flow flowing into the catalyst bed plays the most important role. In this study, the flow characteristics in the SCR reactor in the design stage were simulated using a three-dimensional numerical analysis technique to confirm the uniformity of the airflow. Due to the limitation of the installation space, the shape of the inlet duct was compared with the two types of inlet duct shape because there were many curved sections of the inlet duct and the duct size margin was not large. The effect of inlet duct shape, guide vane or mixer installation, and venturi shape change on SCR reactor internal flow, airflow uniformity, and space utilization rate of ammonia concentration were studied. It was found that the uniformity of the airflow reaching the catalyst layer was greatly improved when an inlet duct with a shape that could suppress drift was applied and guide vanes were installed in the curved part of the inlet duct to properly distribute the process gas. In addition, the space utilization rate was greatly improved when the duct at the rear of the nozzle was applied as a venturi type rather than a mixer for uniform distribution of ammonia gas.

The commercialization of the fifth generation (5G) mobile systems has quested enabling technologies, such as intelligent reflecting surface (IRS) transmissions, towards the sixth generation (6G) networks. In this paper, we present a bit-error rate (BER) performance analysis on IRS transmissions in 5G non-orthogonal multiple access (NOMA) networks. First, we derive a closed-form expression for the BER of IRS-NOMA transmissions under Rician fading channels. Then, by Monte Carlo simulations, we validate the proposed approximate BER expression, and show numerically that the derived BER expression is in good agreement with Monte Carlo simulations. Furthermore, we also analyze the BER performance of IRS-NOMA networks under Rician fading channels with different numbers of reflecting elements, and demonstrate that the performances improve monotonically as the number of reflecting devices increases.

In this paper, the effect of porosity on the acoustic phase velocity of the 3D printed Kelvin closed-cell structure was investigated using the spectral phase analysis. Since Kelvin cells bring about the large amount of scattering, acoustic pulses in ultrasonic measurements undergoes a distortion of waveforms due to the dispersion effect. In order to take account on the dispersion, mathematical expressions for calculating the phase velocity of longitudinal waves propagating normal to the plane of the Kelvin structure are suggested by introducing a complex wave number based on Fourier transform. 3D Kelvin structure composed of identical unit-cells, a polyhedron of 14 faces with 6 quadrilateral and 8 hexagonal faces, was developed and fabricated by 3D CAD and 3D printer to represent the micro-structure of porous materials such as aluminum foam and cancellous bone. Total nine samples of 3D Kelvin structure with different porosity were made by changing the thickness of polyhedron. Ultrasonic pulse of 1MHz center frequency was applied to the Kelvin structures for the measurement of the phase velocity of ultrasound using the TOF(time-of-flight) and the phase spectral method. From the experimental results, it was found that the acoustic phase velocity decreased linearly with the porosity.

The study examined a sentiment analysis based on Tweeter messages between contemporary pop musicians and classical music composers. Musicians of each genre were carefully selected for the sentiment analysis. Many opinion messages on Tweets that users have discussed were collected, and the messages were evaluated by using Naïve Bayes Classifier. The results demonstrated that users showed high positive sentiments for the two different genres. However, on average, the positive sentiment values for classical music composers are higher than for contemporary pop musicians. In addition, the rankings of the highest positive sentiments among contemporary pop musicians and classical music composers did not coincide with the popularity of the two different genres of musicians. This study will contribute to the study of future sentimental analysis between music and musicians.

Recently, rapid climate change has had a significant impact on the ecosystem of honeybees. In addition, the problem of Vespa Hornets invasion of colonies has a fatal impact on the bee ecosystem, independent of climate change. Especially in late summer. This study relates to a method for preventing Vespa Hornets attack. In this study, we developed a Vespa Hornets sound detection device was developed by collecting and analyzing the sound of a Vespa Hornets and applying IoT technology. The developed device detects the sound of a Vespa Hornets when Vespa Hornets appears around the hive of the bees and sends a signal to automatically close the door of the beehive. The device that receives the signal drives the motor that controls the honeycomb door to close the beehive door. The Vespa Hornets sound detection device operates until no Vespa Hornets sound is detected. The system developed by us is expected to be installed in the beehives of actual beekeeping farms to dramatically reduce the damage caused by by Vespa Hornets.

The world is paying a lot of attention to digital twins to preoccupy future technological competitiveness. Digital twins can be used in various fields such as manufacturing, medical care, and cities. Various market research institutes predict that the market size of digital twins will gradually expand. Korea has also selected digital twin as one of the representative tasks of the Korean version of the New Deal and is promoting related policies. However, a common platform or standard for building digital twins is not enough. Interoperability is a very important characteristic for the purpose of creating new value through interconnection between digital twins rather than independently developing and utilizing digital twins. The Digital Twin Consortium is an international council for the effective development and utilization of digital twins, and is working to solve the problem of digital twin interoperability. The Digital Twin Consortium recently published the 'Digital Twin System Interoperability Framework', and this paper analyzes the digital twin interoperability based on it.
