The Covid 19 pandemic officially broke out in Jan 2020 and ended in Mar.2023, following the WHO, claiming 7 million lives. For the three years, while the world made concerted effort to fight against the deadly virus, South Korea was praised as a model country in that the country effectively contained the spread of the virus. Given this, the paper aims to figure out how South Korea's story was quoted by looking at six editorials in the New York Times and the Washington Post. For this aim, we have analyzed linguistic expressions within White (2003)'s appraisal theory and then conducted a key word frequency analysis. The analysis results as follows: first South Korea's story was quoted to criticize the U.S. government of its wrong management to the Covid-19, also giving some lessons to the world; second, both newspapers attribute the South Korea's success to its swift and rapid response to the pandemic; and third, the Washington Post showed more positive attitude to South Korea than the New York Times by quoting the country's success more frequently with more positive words in evaluating the country's responses to the pandemic while both newspapers showed negative attitudes to the U.S. government to the issue. Thus, it can be concluded that linguistic expressions in quotations are effectively used in showing the newspapers' attitude toward South Korea and the U.S.

The domestic gaming industry is a globally competitive field, but growth has recently slowed and competition in overseas markets is intensifying. Accordingly, it is important to analyze the investment status of the domestic gaming industry and study ways to revitalize it. The game industry is a labor-intensive, high-value-added industry that occupies an important position in the domestic content industry. However, the number of businesses and employees has been steadily decreasing for several years, and polarization within the industry is worsening. This is the effect of a decrease in investment in an industrial structure in which labor costs are the majority of production costs. Accordingly, we analyze the current status of the domestic gaming industry, and also analyze the investment status of the gaming industry and the investment structure of domestic venture capital to study the scale and required period of investment and investment projects needed to promote the industry. In this study, "the investment status of the domestic gaming industry and proposed revitalization measures. We study cooperation between the government, businesses, and academia to solve the problem of declining investment and slowing growth." We expect to strengthen competitiveness and continue to grow as we pursue revitalization plans.

Foreign scholars pointed out that the root of the Korean economic crash was A Study on Corporate Social Responsibility and Moral Management due to the government's excessive regulations, the harmful effects of government finance, and the high-cost political structure. Despite the need to ease the rigidity of governmental finance and various regulations and operate the financial system through autonomous market mechanisms, it was argued that various bribes, express fees, and collusive lobbying funds were inevitably generated due to discretionary acts of bureaucrats with licenses and permits, complicated administrative procedures and systems, and regulatory changes in government policies. In fact, in developing countries, corruption was a necessary evil for economic development and was seen as a lubricant in economic management. The purpose of this study is to study the social responsibility and corporate ethics of chaebol. First: consider the problems of large corporations. Second, We will consider the direction and policy of corporate ethics. This paper sheds light on the ethical management of the Korean chaebol, considering that corporate ethics and transparency for the social responsibility of chaebols are important

This study analyzes and compares the roles and significance of large firms in economic growth by differentiating developmental stages. The focus is on both the role of big businesses on the road from middle- to high-income countries and the performance in their economies. By classifying the top 30 nonfinancial firms into their origin countries, we have constructed a country-level data basis covering 33 countries ranging from middle- to high-income economies for the 2001 to 2017 period. We conduct fixed effect estimation. Empirical results show that capital-intensive big businesses would be more predominant in developed economies. In terms of policy implications, the results suggest that if policymakers want to optimize the role of big businesses in economic growth, policymakers need to distinguish the income level. Policymakers also need to adjust the size distribution of firms moderately ahead of time to create the size distribution of firms needed to take the economy to the next level.

In this paper, we examine American career self-help advice in the context of white-collar labor market changes in the U.S., especially how it tries to motivate and empower white-collar job seekers and how fundamentally flawed this is. In this regard, we focus on What Color Is Your Parachute? by Richard Nelson Bolles, as it is the foundational and representative literature in the field of career self-help advice. We first look at the white-collar labor market changes in the U.S. and the growth of career self-help advice along with its influence. We then show that What Color Is Your Parachute? seeks to motivate and inspire job seekers by defining job searching in individual terms and overlooking its structural nature. From this, we point out the most problematic aspect of career self-held advice, i.e., shifting job search responsibility as well as its outcome solely to individual job seekers, while also making it difficult to scrutinize and understand the broader context affecting job searching.

Through the utilization of a contrastive analysis of English consonantal phonemes and their Russian counterparts, the present study investigates the challenges faced by Russian EFL learners in pronouncing English consonantal phonemes, with a particular focus on phoneme substitution errors as a principal source of erroneous pronunciation. We comprehensively explore the characteristics of both the English and Russian consonant systems, highlighting the differences between them. Based on this examination, the study aims to present the detailed articulatory characteristics and phonetic variations of Russian speakers' common mispronunciations or improper substitutes of English consonants, rather than focusing on shared ones between the two languages. Furthermore, it seeks to provide strategies for error correction and effective pedagogical strategies to address specific phonemic challenges and enhance accuracy. Grounded in a comprehensive understanding of the objectives and advantages of comparative analysis within the context of phonemic awareness, the study emphasizes the significant importance of pronunciation instruction. It points out that this area still appears somewhat overlooked in specific EFL teaching situations within the context of English language education.

As globalization has accelerated, the use of English loanwords is increasing in South Korea. In this paper, we have analyzed news stories from four Korean quality newspapers-Chosun Ilbo, Dong-A Ilbo, KyungHyang Sinmun, and Chung-Ang Ilbo to investigate the usage of English loanwords in news texts. Thirty-eight news stories on life, politics, business and IT were collected from the four newspapers and then analyzed based on the five types of loanwords-Direct, Mixed Code Combination, Clipping and Neologism and Double Notation, partly following Lee's and Rudiger's classification. As a result, the followings were revealed: first, the use of the category Direct was overwhelming the others with 90%, indicating that English loanwords were not translated from its source language and introduced into Korean directly with little modification; second, the use of English loanwords was significantly higher in the sections of business and IT than in other sectors, implying that English loanwords function in a similar way as a lingua franca does within those fields. Furthermore, the linguistic trends can provide a basic guide for translators to make an informed decision between the use of English loanwords and its translated Korean version in English-into Korean translation.

This study addresses the challenge of objectively evaluating the performance of early-stage startups amidst limited information and uncertainty. Focusing on companies selected by TIPS, a leading private sector-driven startup support policy in Korea, the research develops a new indicator to assess technological efficiency. By analyzing various input and output variables collected from Crunchbase and KIND (Korea Investor's Network for Disclosure System) databases, including technology use metrics, patents, and Crunchbase rankings, the study derives technological efficiency for TIPS-selected startups. A prediction model is then developed utilizing machine learning techniques such as Random Forest and boosting (XGBoost) to classify startups into efficiency percentiles (10th, 30th, and 50th). The results indicate that prediction accuracy improves with higher percentiles based on the technical efficiency index, providing valuable insights for evaluating and predicting startup performance in early markets characterized by information scarcity and uncertainty. Future research directions should focus on assessing growth potential and sustainability using the developed classification and prediction models, aiding investors in making data-driven investment decisions and contributing to the development of the early startup ecosystem.

We aimed to see if approach-avoidance visual experience would have different effects in the valence rating of emojis. Previous literature has shown that approach-avoidance tendencies have influences people's emotional perceptions. Up until now, research on emojis have been heavily focused on static emojis, which gives room for exploration whether if movement added on to emoji would elicit different emotional responses. In the study, we examined the impact of approach-avoidance visual experience of emojis via mobile interface, categorized into 4 experimental conditions (positive approach, negative approach, positive avoid, and negative avoid), and conducted semi-structured interviews to identify users' reasonings towards their valence ratings on specific emojis with approach or avoid movements. We found that positive approach emojis were the highest valence rating and preferred by the participants, while there were no differences between negative emoji approach or avoidance. Based on these findings, we conclude that positive emojis could be intensified to be more positive with approach motion, yet for negative emojis, individual differences or contextual differences may arise in its emotional ratings.

This study is a cross-sectional research study that analyzed the relationship between emotional regulation behavior and knowledge related to dementia among various age groups in order to collect basic data to reveal the relationship between the characteristics of emotional regulation of dementia patients before dementia and the symptoms of rapid emotional change after dementia. Data collection was from March 1 to March 20, 2024, and a total of 223 people were voluntarily participating in the study from their 20s to 70s. The collected data were t-test, ANOVA, Pearson correlation, and regression analysis using sps 18.0. The analysis showed that people who normally act pretentiously were not related to dementia-related knowledge, but those who act honestly had an impact on dementia-related content knowledge (t=14.808, p<0.01), treatment knowledge of dementia (t=7.916, p<0.01), and knowledge of nursing dementia (t=12.453, p<0.01) under a statistical significance level. And it was found that the inner behavior of emotional regulation behavior had an effect on dementia knowledge at 49.8%, the effect on treatment knowledge was 22.1%, and the effect on nursing knowledge was 41.2%. (p<0.01). Based on the results of this study, we propose a continuous study on how emotional behavior before dementia is related to rapid emotional change behavior after dementia disease.

This paper delves into the application of Gestalt psychology principles in logo design. It analyzes how these principles refine design elements to bolster the efficiency and impact of visual communication. Drawing from Gestalt psychology perspectives, the theoretical foundations and application methods of logo design simplification strategies are discussed. Through the analysis of Gestalt psychology effects in various types and styles of logo designs, this study compares the applicability and differences of logo design simplification strategies under different cultural and social contexts. Furthermore, it evaluates their role and value in enhancing the innovativeness and communicative impact of logo designs. The findings suggest that strategies informed by Gestalt psychology significantly improve the organization rules within logo designs, such as the relationship between figure and ground, proximity, similarity, and continuity. Thereby they enhance perceptual clarity, cognitive load, and aesthetic satisfaction. Moreover, these strategies promote creative thinking and problem-solving abilities in logo design. The results indicate that simplified design methods not only enhance aesthetic appeal but also improve the adaptability and recognizability of logos across different media and environments. This approach aligns with the minimalist and flat design trends of today's information age, meeting the evolving needs and aesthetic preferences of consumers.

This study aims to empirically analyze the effects of leadership level and toxic leadership on leadership performance results among male and female military leaders in the Army, and to verify whether the leader's gender has a moderating effect in this process. Additionally, by comparing and analyzing the leadership level, toxic leadership, and leadership performance results of female military leaders by position, this study seeks to examine the characteristics of female military leadership according to position. The research model was established with leadership level and toxic leadership as independent variables, leadership performance results as the dependent variable, and the leader's gender as a moderating variable. Data were collected through a survey of 216 male and female officers serving in the positions of platoon leader, company commander, and battalion commander in the Army. The collected data were analyzed using descriptive statistics, reliability analysis, correlation analysis, and hierarchical regression analysis. The results showed that leadership level had a significant positive effect on leadership performance results, while toxic leadership had a significant negative effect. The leader's gender moderated the relationship between leadership level and leadership performance results, with female leaders receiving lower evaluations than male leaders at the same level of leadership competency. Gender also moderated the relationship between toxic leadership and leadership performance results, with female leaders exhibiting the same level of toxic leadership receiving lower performance evaluations than male leaders. In the comparative analysis of female military leadership characteristics by position, the leadership level of the platoon leader and company commander groups was not significantly different from that of male soldiers, but the battalion commander group showed slightly lower leadership competency compared to male soldiers. Based on these results, this study suggests ways to improve the leadership level of female military leaders, reduce toxic leadership, and prepare support measures to strengthen the leadership competency of female military officers at the battalion commander level and above from policy, institutional, and educational perspectives.

This study analyzes the current status and prospects of Iran's air defense network, focusing on the Russian-made S-300 system, and derives implications for the development of South Korea's air defense network. Iran's air defense network exhibits strengths such as long-range detection and interception capabilities, multi-target processing, high-altitude interception, and electronic warfare response. However, it also reveals weaknesses, including lack of mobility, difficulty in detecting low-altitude targets, obsolescence, training level of operating personnel, and vulnerability to electronic warfare. Real-world cases confirm these weaknesses, making the system susceptible to enemy evasion tactics, swarm drone attacks, and electronic warfare. Drawing from Iran's case, South Korea should establish a multi-layered defense system, strengthen low-altitude air defense and electronic warfare capabilities, foster the domestic defense industry for technological self-reliance, and enhance international cooperation. By addressing these aspects, South Korea can establish a robust air defense network and firmly protect its national security. Future research should aim to secure and analyze materials from the Iranian perspective for a more objective evaluation of Iran's air defense network and continuously track Iran's efforts to improve its air defense network and the trend of strengthening drone forces to predict changes in the Middle East security situation.

Within five years of Kim Jong-un's rise to power, North Korea conducted four nuclear tests and launched the Hwasong-15, an intercontinental ballistic missile (ICBM), in 2017, declaring the completion of its nuclear forces. During the period when Kim Jong-un completed nuclear forces to maintain the regime, foreign policy factors of the United States, China, Russia, and South Korea drove North Korea's accelerated nuclear development. The main motivating factors were the hostile policies and external threats as security factors. The completion of nuclear forces is also the result of the interplay of domestic political factors, normative factors, and hereditary factors. North Korea has been developing nuclear weapons and missiles for the survival of its regime. To achieve lasting peace on the Korean Peninsula, a new modus vivendi must be sought. It is necessary to set the ultimate goal of North Korea's complete denuclearization and engage in strategic thinking for a realistic and effective phased approach.

This study aims to explore improvement measures for the linkage system between the police and social welfare agencies in responding to domestic violence and child abuse issues in South Korea by comparing and analyzing the current systems in South Korea, the United States, and the United Kingdom. Despite the legal and institutional foundations for victim protection and perpetrator correction in each country, the effectiveness of actual cooperation faces several limitations. In South Korea, the level of cooperation is insufficient due to the lack of information sharing, role conflicts, and ambiguity of cooperation procedures. The United States and the United Kingdom operate more systematic cooperation programs, showing notable achievements in mental health crisis intervention and domestic violence response. To improve the linkage system in South Korea, this study proposes the following measures: (1) developing a clear cooperation protocol, (2) conducting regular education and training programs, (3) establishing an integrated information system, and (4) strengthening the victim-centered approach. Implementing these measures will contribute to more effective responses to domestic violence and child abuse issues, ultimately leading to a healthier and safer society by reducing social costs through victim protection and perpetrator correction.

In Dangjin, Chungcheongnam-do, there are not only power plants and large steel complexes, but also small and medium-sized air pollutant emission facilities. The dust generated by these facilities has a very small particle size and a large surface area due to condensation and physical and chemical reactions, and is discharged containing various harmful substances. Therefore, this study analyzed the distribution of particulate matter and heavy metal concentrations by particle size in the vicinity of the steel complex, residential area, and reference point using an eight-stage Cascade Impactor. Overall, the direct impact sites with a short distance from the steel complex had the highest concentration, followed by the indirect impact sites, and the non-impact sites had the lowest concentration, indicating that they are directly affected by the steel complex. The atmospheric dust concentration distribution showed a bimodal distribution with a minimum value around the 1.1 to 2.1 ㎛ particle diameter. However, during the yellow dust event, the maximum concentration was biased toward coarse particles. The proportion of PM2.5 in the dust tended to be higher in winter, while the ratio between PM2.5 and PM10 was relatively higher in spring. Regardless of the location of the impact point, heavy metals in the dust were dominated by iron and aluminum, followed by zinc, lead, and manganese.

We are designed to solve cyber motion sickness, an important task that must be addressed for the growth of the virtual reality content industry. Not only the industry but also academia are paying a lot of attention. However, despite long interest and research on the phenomenon of cyber motion sickness, a solution has not been drawn. This is deeply related to the lack of tools that can effectively measure cyber motion sickness. Therefore, in this paper, prior studies on cyber motion sickness were analyzed to develop a tool that can effectively measure cyber motion sickness when users experience immersive virtual reality. The measurement method of cyber motion sickness used in previous studies, each characteristic and limitation, and common factors related to cyber motion sickness were analyzed. Each of the related factors was derived as sub-factors. Based on the analyzed contents, an effective cyber motion sickness measurement evaluation tool model in immersive virtual reality was presented. It is expected that the evaluation tool model can be used for the study of cyber motion sickness.

The purpose of this study was to examine the role of parental support in mitigating the impact of discrimination experiences on depression among children and adolescents. This focus was based on the premise that experiences of discrimination can negatively affect peer relationships as well as behavioral and emotional development in youths who spend a significant amount of time with their peers at school. We aimed to explore the mediating role of parental support and to present policy and practical recommendations from a social welfare perspective. For this purpose, data from the "2020 Survey on the Human Rights of Children and Adolescents" was utilized, involving 9,000 students ranging from 4th to 6th grade in elementary school, grade in middle school, and grade in high school from across the country. The study was conducted targeting these groups. For research analysis, frequency analysis using SPSS 26.0 was employed to calculate the general characteristics of the study subjects and the reliability coefficient of the testing tool. And regression analysis was conducted to verify the mediating effect of parental support on the impact of discrimination experiences on depression. The analysis revealed that there were 4,473 males (51.9%) and 4,150 females (48.1%), and that experiences of discrimination had a negative effect on depression (B=311, P<0.001). It was found that the more frequent the experiences of discrimination, the higher the level of depression, and the more a youth experienced discrimination, the greater the psychological depression they endured.

During an X-ray examination, the beam of radiation is dispersed in many directions. We believe that managing radiation dose is about providing transparency to users and patients in the accurate investigation and analysis of radiation dose. The purpose of measuring the radiation dose as a function of location is to ensure that medical personnel using the equipment or participating in the operating room are minimally harmed by the different radiation doses depending on their location. Four mobile diagnostic X-ray units were used to analyze the radiation dose depending on the spatial location. The image intensifier and the flat panel detector type that receives the image analyzed the dose by angle to measure the distribution of the exposure dose by location. The radiation equipment used was composed of four units, and measuring devices were installed according to the location. The X-ray (C-arm) was measured by varying the position from 0 to 360 degrees, and the highest dose was measured at the center position based on the abdominal position, and the highest dose was measured at the 90° position for the head position when using the image intensifier equipment. The operator or medical staff can see that the radiation dose varies depending on the position of the diagnostic radiation generator. In the image intensifier and flat panel detector type that accepts images, the dose by angle was analyzed for the distribution of exposed dose by position, and the measurement method should be changed according to the provision of dose information that is different from the dose output from the equipment according to the position.

In the context of contemporary digital media, virtual influencers have become an increasingly important form of socialization and entertainment, in which emotional expression is a key factor in attracting viewers. In this study, we take Luo Tianyi, a Chinese virtual influencer, as an example to explore how emotions are expressed and perceived through facial expressions in different types of videos. Using Paul Ekman's Facial Action Coding System (FACS) and six basic emotion classifications, the study systematically analyzes Luo Tianyi's emotional expressions in three types of videos, namely Music show, Festivals and Brand Cooperation. During the study, Luo Tianyi's facial expressions and emotional expressions were analyzed through rigorous coding and categorization, as well as matching the context of the video content. The results show that Enjoyment is the most frequently expressed emotion by Luo Tianyi, reflecting the centrality of positive emotions in content creation. Meanwhile, the presence of other emotion types reveals the virtual influencer's efforts to create emotionally rich and authentic experiences. The frequency and variety of emotions expressed in different video genres indicate Luo Tianyi's diverse strategies for communicating and connecting with viewers in different contexts. The study provides an empirical basis for understanding and utilizing virtual influencers' emotional expressions, and offers valuable insights for digital media content creators to design emotional expression strategies. Overall, this study is valuable for understanding the complexity of virtual influencer emotional expression and its importance in digital media strategy.

The study introduces and validates a model of post-traumatic growth among parents of children with special needs. The model incorporates cognitive processes, coping strategies, and sociocultural factors as intra-personal variables. The statistical analysis unveiled significant pathways that connect the factors, explaining 71% of the variance associated with post-traumatic growth. The study highlighted intentional reflection and robust decentralization skills as crucial factors that predict post-traumatic growth. Deliberate rumination functioned as a mediating factor, reducing the impact of trauma and facilitating post-traumatic growth, while social support played a crucial role in initiating purposeful rumination. The study findings indicate that the effect of self-disclosure on post-traumatic growth is not direct but rather indirect, as it is mediated by its influence on social support and deliberate rumination. The study underscores the significance of examining particular characteristics of social support networks and suggests integrating additional variables for future research, such as gender, types of traumatic events, and the age of children with disabilities.
