The pandemic situation caused by COVID-19 has a large and small impact on our society socially, economically, psychologically, and other aspects. In order to prevent the spread of COVID-19, various countries, including Korea, have entered into long-term home care and distance learning systems. However, distance learning experiments conducted in many countries have raised whether face-to-face education can be replaced by distance learning. Therefore, in this study, public opinion, social perception, and field trends were analyzed based on media reports on distance learning. For this purpose, 2,600 articles from 11 newspapers and four broadcasters related to distance learning were collected in this study. Based on this data, keyword trend analysis, topic modeling analysis, sentiment analysis were performed.

This study focused on analyzing the contents of social big data produced in the online space, dealing with issues related to food in the community in the context of COVID-19. First, this study analyzed food-related issues that spread through regional websites and online community(cafes) after social distancing was implemented due to COVID-19. Next, this study analyzed the contents of food-related issues that spread through media news, SNS, and portals. As a result, there were more food-related posts on the homepages of other regions compared to the metropolitan areas such as Seoul and Gyeonggi, but in the case of online communities, there were more food-related issues in online communities registered in Seoul and Gyeonggi regions. Food-related keywords in regional online communities mainly contained content related to the local economy. In the media articles, SNS, and search portal issues, content that can be discussed in the consumption process of local community food-related policies, information, and products mainly appeared. Based on the results of the study, it was found that there is no specialized information sharing system for each community, that online communities can contribute to providing food information applicable to reality, and that it is possible to verify the performance of regional food policies through social media.

Films of the 1960s in both Korea and Egypt share many common characteristics. These include the main trend of such films' in addition to some of the political situations. This trend mainly relates to the adaptation of novels into films. In the late 1940s, Andre Bazin wrote his ideas about a similar phenomenon in Europe and the United States. Based on Bazin's thoughts and other examples for films adapted from novels in the 1940-60s, I found that the trend in both Korea and Egypt can be explained as an international phenomenon, in which film developed to a further stage due to a dialectic between content and form after the increase in the development of film techniques. The trend in Korea is believed to have led to the so-called golden era of Korean movies, while in Egypt films adapted from literature were not able to earn high profits, even though in a 1996 list of the best 100 Egyptian films, 23 had been adapted from novels. To explain the reasons behind this phenomenon, I looked into the internal demand from filmmakers themselves to further develop the industry through the articles written at that time. In addition, I explored the different situations and policies that influenced film production in both countries in the 1960s. I found that political situations and policies could have helped in the continuity of such trend, but it is difficult to consider these as the main reason for its creation, in contrast to the internal demand, which I believe is the main reason for the creation of such direction.

As global energy crisis and the COVID-19 pandemic have emerged as social issues, there is a growing demand for companies to move away from profit-centric business models and embrace sustainable management that balances environmental, social, and governance (ESG) factors. ESG activities of companies vary across industries, and industry-specific weights are applied in ESG evaluations. Therefore, it is important to develop strategic management approaches that reflect the characteristics of each industry and the importance of each ESG factor. Additionally, with the stance of strengthened focus on ESG disclosures, specific guidelines are needed to identify and report on sustainable management activities of domestic companies. To understand corporate sustainability strategies, analyzing ESG reports and news articles by industry can help identify strategic characteristics in specific industries. However, each company has its own unique strategies and report structures, making it difficult to grasp detailed trends or action items. In our study, we analyzed ESG reports (2019-2021) and news articles (2019-2022) of six companies in the 'Finance,' 'Manufacturing,' and 'IT' sectors to examine the sustainability strategies of leading domestic ESG companies. Text mining techniques such as keyword frequency analysis and topic modeling were applied to identify industry-specific, ESG element-specific management strategies and issues. The analysis revealed that in the 'Finance' sector, customer-centric management strategies and efforts to promote an inclusive culture within and outside the company were prominent. Strategies addressing climate change, such as carbon neutrality and expanding green finance, were also emphasized. In the 'Manufacturing' sector, the focus was on creating sustainable communities through occupational health and safety issues, sustainable supply chain management, low-carbon technology development, and eco-friendly investments to achieve carbon neutrality. In the 'IT' sector, there was a tendency to focus on technological innovation and digital responsibility to enhance social value through technology. Furthermore, the key issues identified in the ESG factors were as follows: under the 'Environmental' element, issues such as greenhouse gas and carbon emission management, industry-specific eco-friendly activities, and green partnerships were identified. Under the 'Social' element, key issues included social contribution activities through stakeholder engagement, supporting the growth and coexistence of members and partner companies, and enhancing customer value through stable service provision. Under the 'Governance' element, key issues were identified as strengthening board independence through the appointment of outside directors, risk management and communication for sustainable growth, and establishing transparent governance structures. The exploration of the relationship between ESG disclosures in reports and ESG issues in news articles revealed that the sustainability strategies disclosed in reports were aligned with the issues related to ESG disclosed in news articles. However, there was a tendency to strengthen ESG activities for prevention and improvement after negative media coverage that could have a negative impact on corporate image. Additionally, environmental issues were mentioned more frequently in news articles compared to ESG reports, with environmental-related keywords being emphasized in the 'Finance' sector in the reports. Thus, ESG reports and news articles shared some similarities in content due to the sharing of information sources. However, the impact of media coverage influenced the emphasis on specific sustainability strategies, and the extent of mentioning environmental issues varied across documents. Based on our study, the following contributions were derived. From a practical perspective, companies need to consider their characteristics and establish sustainability strategies that align with their capabilities and situations. From an academic perspective, unlike previous studies on ESG strategies, we present a subdivided methodology through analysis considering the industry-specific characteristics of companies.

The purpose of this study was to investigate consumers' perceptions on monosodium L-glutamate (MSG) in social media. Data were collected from Naver blogs and Naver web communities (Korean representative portal web-site), and media reports including comment sections on a Yonhap news website (Korean largest news agency). The results from Naver blogs and Naver web communities showed that it was primarily mentioned MSG-use restaurant reviews, 'MSG-no added' products, its safety, and methods of reducing MSG in food. When TV shows on current affairs, newspaper, or TV news reported uses and side effects of MSG, search volume for MSG has increased in both PC and mobile search engines. Search volume has increased especially when TV shows on current affairs reported it. There are more periods with increased search volume for Mobile than PC. Also, it was mainly commented about safety of MSG, criticism of low-quality foods, abuse of MSG, and distrust of government below the news on the Yonhap news site. The label of MSG-no added products in market emphasized "MSG-free" even though it is allocated as an acceptable daily intake (ADI) not-specified by the Joint FAO/WHO Expert Committee on Food Additives (JECFA). When consumers search for MSG (monosodium L-glutamate) or purchase food on market, they might perceive that 'MSG-no added' products are better. Competent authorities, offices of education and local government provide guidelines based on no added MSG principle and these policies might affect consumers' perceptions. TV program or news program could be a powerful and effective consumer communication channel about MSG through Mobile rather than PC. Therefore media including TV should report item on monosodium L-glutamate with responsibility and information based on scientific background for consumers to get reliable information.

This study focuses on the fact that students and teachers commonly have difficulty in 'selecting the topic' in many activities including student-led research that is conducted from topic selection to the drawing of conclusion. The purpose of this study is to develop a manual for science teaching research. The instructional manuals of 4 stages were developed based on practical knowledge that can be implemented in the actual class through previous research and literature. Each stage is composed of , , , and . In the third stage, students are expected to find scientific questions and develop them into research topics through detailed class research on newspaper articles, scientific magazines, traditional knowledge, proverbs, daily life, and textbook experiments. In the experimental group, the final research topic was selected through a variety of sources such as textbook experiments, proverbs, YouTube images, newspaper articles, individual WHY NOTEs, and understood the conditions of the scientific research topic and expressed the variables in the research title. However, in the control group, some students did not consider the research scope of the selected research subjects to be specific or not to be able to study at their level. As a result of giving the students as much autonomy as possible, many groups did not fully understand the previous research and submitted it. Based on the results of this study, it can be concluded that development and use of a 'topic selection stage' centered practice manual for general high school teachers would not only improve the students' abilities to discover solutions to scientific questions, but it will also help shift their attitudes towards science in a positive direction.

본 연구는 1960년대 미국의 청년층에 의해 일어난 반문화적인 현상으로 인식되어온 동양문화의 도입, 특히, 인도문화가 청년문화 전반에 끼친 영향과 더 나아가 이러한 환경변화가 미국대학복식에 미친 영향을 알아보고자 하였다. 1960년대 미국청년문화에 나타난 인도 문화의 영향은 철학, 종교 대중음악 등 다방면에서 보여졌으며, 또한 복식의 형태에도 반영되었다. 복식학자들에 의한 단편적인 추론에만 그쳤던 이러한 복식의 현상을 본 연구는 문헌조사에 의한 객관적이고 과학적인 연구방법을 이용하여 입증하고자 시도하였다. Washington, D.C.와 San Francisco/Berkeley 지역에 위치한 7개의 대학교에서 1960년 부터 1975년 사이에 발행한 대학신문에서 연구자료를 수집하여, 체계적인 자료수집 및 분석을 위한 연구방법으로 사회과학분야에서 주로 사용되어 온 Content Analysis Method를 이용하였다. Content Analysis Method는 예비연구(preliminary study)의 결과를 기초로 인도 복식의 영향을 받은 미국대학복식의 형태를 크게 의복(clothes), 장신구(accessories), 직물(fabrics) 등의 3개 category로 분류하여, 다시 13개의 subcategory(kurta, midriff top, Nehru jacket/suit, Indian shirt/blouse/smock/dress, sari, Indian jewelry, Indian sandal, Indian urn, Indian bedspread. Indian embroidery, Indian print, madras, tie-dye)로 세분하였다. 복식의 형태에 의한 분류외에도, 대학신문의 광고나 기사에 실린 내용을 인도복식이 미친 엮향의 정보를 알아보기 위하여 Attribution information을 3 category(originated, attributed, connotated)로 분류하여 조사하였다. 더불어, 같은 문헌에 나타난 인도에서 도입된 4개의 주된 종교(Transcendental Meditation, Hare Krishna, Yoga. Divine Light Mission)의 빈도도 조사하였다. 본 연구의 결과는 13개의 가인도복식스타일(Indian style)의 Frequency(빈도), Attribution, Duration(기간)의 내응을 포함하는 표로 요약되었다. 또한, 연도별로 Indian style이 나타난 빈도의 Duration(기간)의 내용을 포함하는 표로 요약되었다. 또한, 연도별로 Indian style이 나타난 빈도의 합계와 연도를 축으로 하는 막대그래프를 작성하고 이 그래프에 Attribution Category의 내용도 함께 볼 수 있도록 정리하였다. 대학복식에 나타난 인도의 영향은 여성복식과 남성복식에 있어서 서로 유사점과 차이점이 보이는데, 인도의 영향이 여성복식에 있어서 그 빈도가 더 높고, 종류가 더 다양함을 볼 수 있다. 여성복식에 있어서는 12가지의 다양한 인도복식스타일이 나타났으며, 그중 가장 많이 보이는 스타일은 Indian Shirt/Blouse/Smock/ Dress이며, 그 뒤를 이어 Madras, Indian lowery등을 볼 수 있다. 남성복식애 나타난 7가지의 스타일 중에는 Madras가 가장 빈도가 높으며 그외의 스타일들은 그 빈도가 매우 낮음을 볼 수 있다. 인도의 영향의 정도 (Attribution Categories) 있어서는 여성과 남성복식 모두에 있어서 인도에서 직접 수입된(originated) item이 각각 전체의 90%와 81%를 차지하여, 인도복식의 영향은 받았으나 미국내에서 제작된(attributed and connotated) item 보다 휠씬 더 많은 수를 보였다. 인도복식스타일이 가장 많이 보여지는 시기(Peak period)는 여성과 남성복식에 있어 모두 1968년에서 1971년 사이로 공통점을 보였다. 이러한 결과는 미국 청년 문화에 전반적으로 나타났던 반문화적 현상과 동일한 시기로서, 이는 사회 현상이 복식에도 반영되고 있음을 알 수 있다. 또한 같은 시기의 대학신문에 나타난 인도에서 도입된 4 개의 종교 역시 1960년대 후반 부터 그 빈도가 증가하여 1970년에 리고의 빈도가나타낭으로서 앞의 결과를 뒷받침해 주고 있다. 본 연구에서는 Washington,D.C.와 San Francisco/Berkeley 지역의 대학신문만을 연구자료로 사용하였으나 앞으로는 새로운 연구 자료의 발굴과 연구대상을 타 지역으로 확대시키므로서 미국내 전체의 청년복식에 대한 이해를 증가시킬 수 있을 것이다.

This study analyzed the contents of letters-to-the-editor and the characteristics of the letters' writers, featured in three major newspapers, Chosun Ilbo, Dong-a Ilbo and Hankyoreh, in Korea from 1997 to 2009. Additionally, based on whether the letters contained the feedback function or not, it scrutinized the attributes of the letters-to-the-editor. The results indicated that the role of letters-to-the-editor has changed from a space for showing merely personal dissatisfactions or complaints into a space for expressing the reader's opinions about various issues. The study also showed that the proportion of writers who have specialized jobs and are members of civic groups steadily increased. It seems to tell that the quality of the letters was improved accordingly, because they could give in-depth opinions about the matters in which the society were interested. The feedback function of the letters was also gradually more activated for those years, and it could be thought as another evidence supporting the quality improvement of the letters, which were supposed to form the healthful public opinion. However, the writers' residential districts are heavily concentrated on the region surrounding Seoul, the capital of Korea. The study suggested that the newspapers should develop tools to overcome such defects.

Many studies have been conducted to analyze factors that affect customer satisfaction, and service quality improvement in the parcel delivery industry. Most of these studies have a limited number of respondents using methods such as surveys and interviews. Therefore, this study aims to supplement the shortcomings of previous studies, by searching and analyzing the common major topics related to the complaints pointed out by consumers and suppliers in the parcel delivery service with cases of consumer counseling, and articles that reflect the complaints of workers in the industry. In addition, by analyzing the trend of these topics, we attempted to discover new topics and suggest implications. In conclusion, topics such as delay/lost/wrong deliveries as well as the fierce competition in the parcel delivery industry, turned out to be central aspects. As a result of the topic trend analysis, talks with international couriers have recently increased, and many conflicts related to apartment parcel delivery have been dealt with. The topics presented in this study are mainly focused on the contents of previous studies, but we expect that new and valuable topics can be derived by adding other data and analysis methods, such as internal counseling and academic literature.
