The public mostly get the information regarding real estate policy not from the press release of the government but from news articles. This type of information, though, might be delivered in a different frame depending on inclination of media or press. The media runs the articles within its own frame, so that it often conveys either expectation or concern depending on its inclination. This study analyzed the articles regarding 'Agreement to revise three major real estate regulations to perk up property market' and examined how the real estate policy imprinted in them depending on the disposition of the press. The results showed that the conservative press ran articles within a positive frame expressing favorable expectation. On the other hand, progressive press mostly kept neutral or unfavorable tone on the same regulations within the negative frame. Therefore, it was confirmed that there exist different frames within articles depending on their disposition.

There is a more urgent call for educational methods of machine learning in medical education, and therefore, new approaches of teaching and researching machine learning in medicine are needed. This paper presents a case using machine learning through text analysis. Topic modeling of news articles with the keyword 'asbestos' were examined. Two hypotheses were tested using this method, and the process of machine learning of texts is illustrated through this example. Using an automated text analysis method, all the news articles published from January 1, 1990 to November 15, 2016 in South Korea which included 'asbestos' in the title and the body were collected by web scraping. Differences in topics were analyzed by structured topic modelling (STM) and compared by press companies and periods. More articles were found in liberal media outlets. Differences were found in the number and types of topics in the articles according to the partisanship and period. STM showed that the conservative press views asbestos as a personal problem, while the progressive press views asbestos as a social problem. A divergence in the perspective for emphasizing the issues of asbestos between the conservative press and progressive press was also found. Social perspective influences the main topics of news stories. Thus, the patients' uneasiness and pain are not presented by both sources of media. In addition, topics differ between news media sources based on partisanship, and therefore cause divergence in readers' framing. The method of text analysis and its strengths and weaknesses are explained, and an application for the teaching and researching of machine learning in medical education using the methodology of text analysis is considered. An educational method of machine learning in medical education is urgent for future generations.

Objectives: The mass media play a crucial role in risk communication regarding climate change. The aim of this study was to investigate the trend in journalistic reports on climate change in the daily newspapers of Korea. Methods: We selected 9 daily newspapers in Korea, which according to the ABC Association, represented 77% of newspaper circulation, out of a total of 44 Korean daily newspapers. The collected articles were from 2009 to 2011. All of the articles were sorted into the following 8 categories: greenhouse gas, climate change conventions, sea level rise, Intergovernmental Panel on Climate Change synthesis reports, expected damage and effect, use of fossil fuels, global warming, and mitigation or adaptation. A chi-squared test was done on the articles, which were counted and classified into cause, effect, and measurement of climate change according to the newspaper's majority or minority ownership structure. Results: From the 9 selected newspapers, the number of articles on climate change by month was greatest in December 2009. Generally, the articles vague about climate change (lack of precise data, negative or skeptical tone, and improper use of terminology) were much more common than the articles presenting accurate knowledge. A statistical difference was found based on ownership structure: the majority-owned newspapers addressed the cause of climate change, while the minority-owned newspapers referred more to climate change measurement. Conclusions: Our investigation revealed that generally Korean daily newspapers did not deliver accurate information about climate change. The coverage of the newspapers showed significant differences according to the ownership structure.

The purpose of this study is to verify the research trends on 101 articles about mathematical creativity published in domestic journals. The analysis criteria are as follows: (1)What kind of terms the articles use to refer to the creativity in mathematics education, (2)Whether the researchers conceptualize such the terms or not, (3)Whether the definitions are domain-specific or not, (4)What perspectives, categories and levels of the articles have on creativity. The results of this study show the following. First, numerous articles used 'mathematical creativity' in order to point to the creativity in mathematics education. Second, among the 101 selected articles, 60 (59.4%) provided an explicit definition of the mathematical creativity and 19(18.8%) provided an implicit definition. Among the 79 articles, only 43(54.4%) provided domain-specific definitions. Second, the percentage of articles preferring one perspective over the other 3 perspectives were similar. Third, the rate of articles which focused on press(environment) of all categories (person, process, product, press) was low. Fourth, regarding the levels of creativity, most articles were done on little-c creativity level, on the other hand, the articles having an interest in mini-creativity were very rare. Based on these results, necessities of explicit and domestic-specific definition, whole approach of mathematical creativity, and articles focusing on the mini-creativity level should be reported.

This study analyses North and South Koreas' coverage as framed by the main Polish press titles from 1989 to 2019. The main method applied is a computational textual analysis of press articles based on frequency, correlations and co-occurrences. The purpose is to map the topics of the examined articles in the context of relations between Poland and the two Koreas in various areas, predominantly political and economic relations. Emphasis is placed on the impact the carmaker Daewoo's investment in Poland in the mid-1990s had on bilateral Polish-South Korean relations. First, the authors argue that Korean issues in the Polish press, mainly in the second half of the 1990s, particularly concerned economic affairs. Secondly, they argue that after Poland's accession to the European Union in 2004, the country's interest in the two Koreas decreased, and since that time has remained at a more or less constant level. Finally, the authors discuss the outcome of the research in the context of the main developments in Polish-Korean relations, taking into consideration the results of a Polish public opinion survey presenting the international linkages between national public opinion and foreign policy.
