In this study, information search methods and user interface types provided to users were investigated for the top 100 e-commerce services selected by Statista and the National Retail Federation. And the characteristics of each type were derived by analyzing the interaction method of the user's manipulation with the visualization elements constituting the interface. The research results are as follows. First, as the information provision method, spread format was more often used as the number and hierarchy of information increased, and drop-down and mega menu methods were used more often as the number and hierarchy of information decreased. Second, as a visual classification method according to the information hierarchy, the background color, font change, and line were often used, and there were many cases where the background color and line were used at the same time. Third, there were various elements such as background color, text color, and line as an interaction method for user manipulation, and two or more of them were applied at the same time the most. This study is meaningful in that it defines the characteristics of each type through the analysis of the types of interfaces for e-commerce information search and items that can be the selection criteria for detailed elements.

The visual expression of deconstructive graphic design influenced by postmodernism differs from the traditional ways of graphic expression that consist of precise images and text and is challenging and highly experimental. The characteristics of the formative nature of such deconstructive graphic design emphasized the importance of the reader as the principal agent of aesthetic experience in the appreciation of works. For this study, a new ideological framework was developed regarding the ambiguity arising due to visual experimentation in deconstructive graphic design, assuming the central theory to be the Reception Theory (Aesthetics of Reception) centering around the recipient who is the reader. The characteristics of Iser's Reception Theory are substituted as a theoretical category and an interpretation of the works of ambiguity in deconstructive graphic design is carried out. Although Aesthetics of Reception is a literary theory about the interaction between the artist and the reader, as a method for interpreting deconstructive graphic design influenced by postmodernism, it laid a theoretical foundation and enriched the interpretation of works. Moreover, the four characteristics of Iser's Reception Theory were used to create a framework that suggested a new direction for the approach based on the reader's interaction in the process of interpreting works of modern graphic design.

The purpose of this paper is to examine Toegye(退溪 李滉, 1501~1570)'s interpretation of Chungyong(中庸) who led the completion of the $Chos{\breve{o}}n$-style acceptance of Neo-Confucianism. This paper is focused on revealing the way that how he understood it according to the system of Neo-Confucianism that was proposed by Chu Hsi, rather than revealing the unique perspective of Toegye. I have the following configuration in this paper. First, I have set two directions of research for understanding of Chungyong, these were derived through the work that is an overview of cases of interpretation of Chungyong of $Chos{\breve{o}}n$. 1) How to understand the overall structure of Chungyong? 2) How to understand key concepts of Chungyong? Next, basing on these directions of research, I analyzed Toegye's interpretation of Chungyong. To grasp the structure of the whole, Toegye followed the segmentation system and structure of Chungyong changgu: Commentary on the Doctrine of the Mean, and to understand key concepts of Chungyong, he conducted in collaboration with concepts of Neo-Confucianism. Concretely, I analyze his work : Chungyong $suk{\breve{u}}i$(中庸釋義) and Chungyong $jil{\breve{u}}i$(中庸質疑) for asserting that he accepted the segmentation system and structure of Chungyong changgu. And I analyze his documents: letters to and from his disciples. This analysis focus on concepts of Chungyong for asserting that his understanding is in the context of Chu Hsi and other Neo-Confucian scholars's commentary. Toegye tried to reduce the diversity of interpretation and present one meaning.

In a situation where OA papers are increasing, POI, which indexes how open the research activities of individual researchers are, is drawing attention. This study investigated the existence of OA papers and the OA method published in international academic journals by domestic LIS researchers, and derived the researchers' POI based on this. In addition, by examining the relationship between the POI index and the researcher's amount of research papers, the research sub field, and the foreign co-authors, it was analyzed whether these factors are relevant to the researcher's POI. As a result, there were 492 papers by 82 researchers whose OA status and method were normally identified through Unpaywall. Second, only 20.7% of papers published in international journals were open accessed, and almost cases were gold and green methods. Third, there were many papers in text mining in medical journals, and the papers opened in the green method are open in institutional repositories of foreign co-authors or transnational subject repositories such as PMC. Third, the POI index was relatively higher for researchers in the field of informetrics, machine learning than other fields. In addition, it was analyzed that the presence or absence of overseas co-authors is related to OA.

Recently, policies and research to prevent increasing construction accidents have been actively conducted in the domestic construction industry. In previous studies, the prediction model developed to prevent construction accidents mainly used only structured data, so various characteristics of construction sites are not sufficiently considered. Therefore, in this study, we developed a machine learning-based construction accident prediction model that enables the characteristics of construction sites to be considered sufficiently by using both structured and text-type unstructured data. In this study, 6,826 cases of construction accident data were collected from the Construction Safety Management Integrated Information (CSI) for machine learning. The Decision forest algorithm and the BERT language model were used to train structured and unstructured data respectively. As a result of analysis using both types of data, it was confirmed that the prediction accuracy was 95.41 %, which is improved by about 20 % compared to the case of using only structured data. Conclusively, the performance of the predictive model was effectively improved by using the unstructured data together, and construction accidents can be expected to be reduced through more accurate prediction.

This research analyzed articles about the disability under the 「The Disabled Person Welfare Law」 in a major daily newspaper. A total of 7,684 articles on disability were collected from homepages of the three newspapers , , and . Through network text analysis and content analysis, we considered about "The perspective of Disability" based on "Multiple Disability Model". As a result of this research, when comparing individual models versus social models, individual models have a higher rate 64.31% than social models 35.69%. According to the newspapers, the major perception of Disability is a traditional individual model, which means disability must be solved by individuals. In addition, due to low social and institutional supports, the public's attention and consideration required for the disabled, socially weak people. This research implied that despite the changing times of looking at disability, three newspapers are still staying in the traditional paradigm. Therefore, It is required that viewing a disability from the perspective on disabled people, and a mature awareness that recognizes the diversity of individual needs. The significance of this study can be found in the fact that no attempt has been made to treat the disability perspectivec in newspaper articles as quantitative and qualitative data.
