The rapid development of internet technologies and social media over the last few years has generated a huge amount of unstructured text data, which contains a great deal of valuable information and issues. Therefore, text mining-extracting meaningful information from unstructured text data-has gained attention from many researchers in various fields. Topic analysis is a text mining application that is used to determine the main issues in a large volume of text documents. However, it is difficult to identify related issues or meaningful insights as the number of issues derived through topic analysis is too large. Furthermore, traditional issue-clustering methods can only be performed based on the co-occurrence frequency of issue keywords in many documents. Therefore, an association between issues that have a low co-occurrence frequency cannot be recognized using traditional issue-clustering methods, even if those issues are strongly related in other perspectives. Therefore, in this research, a methodology to reorganize social issues from a research and development (R&D) perspective using social network analysis is proposed. Using an R&D perspective lexicon, issues that consistently share the same R&D keywords can be further identified through social network analysis. In this study, the R&D keywords that are associated with a particular issue imply the key technology elements that are needed to solve a particular issue. Issue clustering can then be performed based on the analysis results. Furthermore, the relationship between issues that share the same R&D keywords can be reorganized more systematically, by grouping them into clusters according to the R&D perspective lexicon. We expect that our methodology will contribute to establishing efficient R&D investment policies at the national level by enhancing the reusability of R&D knowledge, based on issue clustering using the R&D perspective lexicon. In addition, business companies could also utilize the results by aligning the R&D with their business strategy plans, to help companies develop innovative products and new technologies that sustain innovative business models.

The purpose of this study is to address the Issues on Architectural Plagiarism through the analysis of the discourses written in texts form. This study selected 60 texts of 20 suspected pairs of architectural plagiarism to derive key-words and key-passages to understand the Issues on Architectural Plagiarism. As a result, the Issues on Architectural Plagiarism are categorized into six different topics; Prototype, Archetype, Motif, Expression of Idea, Commodification, and Westernized-modernization. Meanwhile, the six issues were not discussed independently, but several issues were considered simultaneously in individual cases. This study is the first step to establish the objective guideline to judge Architectural Plagiarism and to be a basis in Architectural Plagiarism research.

The recent rise in the unstructured data generated by social media has resulted in an increasing need to collect, store, search, analyze, and visualize it. These data cannot be managed effectively by using traditional data analysis methodologies because of their vast volume and unstructured nature. Therefore, many attempts are being made to analyze these unstructured data (e.g., text files and log files) by using commercial and noncommercial analytical tools. Especially, the attempt to discover meaningful knowledge by using text mining is being made in business and other areas such as politics, economics, and cultural studies. For instance, several studies have examined pending national issues by analyzing large volumes of texts on various social issues. However, it is difficult to create satisfactory information services that can identify R&D documents on specific national issues from among the various R&D resources. In other words, although users specify some words related to pending national issues as search keywords, they usually fail to retrieve the R&D information they are looking for. This is usually because of the discrepancy between the terms defining pending national issues and the corresponding terms used in R&D documents. We need a mediating logic to overcome this discrep 'ancy so that we can identify and package appropriate R&D information on specific pending national issues. In this paper, we use association analysis and social network analysis to devise a mediator for bridging the gap between the keywords defining pending national issues and those used in R&D documents. Further, we propose a methodology for packaging R&D information services for pending national issues by using the devised mediator. Finally, in order to evaluate the practical applicability of the proposed methodology, we apply it to the NTIS(National Science & Technology Information Service) system, and summarize the results in the case study section.

Analyzing on-line consumer responses is directly related to the management performance of food companies. Therefore, this study collected and analyzed data from an on-line portal site created by consumers about food companies with issues and examined the relationships between the data and the management performance. Through this process, we identified consumers' awareness of these companies obtained from big data analysis and analyzed the relationship between the results and the sales and stock prices of the companies through a time-series graph and correlation analysis. The results of this study were as follows. First, the result of the text mining analysis suggests that consumers respond more sensitively to negative issues than to positive issues. Second, the emotional analysis showed that companies' ethics issues (Enterprise 3 and 4) have a higher level of emotional continuity than that of food safety issues. It can be interpreted that the problem of ethical management has great influence on consumers' purchasing behavior. Finally, In the case of all negative food issues, the number of word frequency and emotional scores showed opposite trends. As a result of the correlation analysis, there was a correlation between word frequency and stock price in the case of all negative food issues and also between emotional scores and stock price. Recently, studies using big data analytics have been conducted in various fields. Therefore, based on this research, it is expected that studies using big data analytics will be done in the agricultural field.

This study aimed to understand the driver change of recent research in relation to rural and migrant and draw overarching issues as well as to provide implications to contribute to migrants' social integration in Korean rural areas. As for the scope and method of the study, data through quantitative bibliographic analysis (quantitative data) and research keywords by period were derived. To address the aim this study employed bibliometric analysis utilising netwok mapping interface analysis by VOSviewer and topic modeling analysis by Netminer. The findings were revealed that firstly mental health issues in abroad research and employment and discrimination in domestic research both derived from migrant mobility constituted staple key issues, secondly internal and external research differed two issues in health and violence where Korea has overlooked the issues seriously. Therefore this study presented implications which are about first, health and violence-related sections for migrants should be specified into domestic law, second domestic-focused MIPEX index should be developed in which the two issues are over-weighted and last such newly emerging approach 'inclusive formation of social psychological mechanisms should be widely spread. Concluding remark is that delivering the implications can be foster to migrants' integration in rural area underlining that this will ultimately contribute to migrants' quality of life.

In this study, the characteristics and patterns of family problems were explored. What constituted family problems, and how those evolved over the period of drastic changes in the Korean society were examined, by analyzing articles published from the 1940s to the 1980s in the four major national newspapers in Korea. A total of 6542 articles related to family problems in the four newspapers, Chosun, Dong-A, Kyunghyang, and Seoul, were used for the content analysis of this study. The main categories of family problems were classified as poverty, marital issues, issues related to children and adolescents, elderly issues, problems in the family as an institution, and the so-called family-lag problem. Each of these categories consisted of several subcategories: The poverty-related problems included the problems caused by difficulty in making a living and instability of living, for example. The marital issues category consisted of conflicts between the couple, unfaithful spouses, domestic violence, divorce, and so on. Issues related to children and adolescents included juvenile delinquency, difficulty in bringing up children, child abuse, single motherhood, and underage household heads, for example. The elderly issues included the anxiety over the aging society, support for the elderly, conflicts between mother-in-law and daughter-in-law, alienation of the elderly, etc. Problems in the family as an institution consisted of the legal issues in such areas as marriage, succession of the family head, and adoption. Lastly, the family-lag problem included confusion over family values, and conflict caused by the inconsistency between consciousness and actual behavior related to the family or family crisis. From the 1940s to the 1980s, family-lag was the most common problem (26.2% of the total articles), followed by issues related to children and adolescents (23.1%), poverty (16.2%), marital issues (15.9%), elderly issues (12.4%), and problems in the family as an institution (6.0%). During the 1940s and the 1950s, poverty was a prominent problem, and in the 1960s, issues related to children and adolescents were most commonly addressed in the articles. In the 1970s and the 1980s, the family-lag problem was the most frequently addressed.
