This study examined factors that prevent older adults from using computers and/or smartphones for their health information search and health management. This study conducted face-to-face survey of a total of 240 older adults aged over 65. Based on the responses of open-ended questions, this study conducted semantic network analysis. The results showed that low level of perceived usefulness(PU) (e.g., information I want to find, detailed information, and trustworthiness) and perceived ease of use(PEOU) (e.g., how to search for information, how to install applications, and visibility) are main factors that prevent older adults from using computers and/or smartphones for their health information search and health management. Furthermore, based on the results of semantic network analysis, further hierarchical regression analysis confirmed that PU and PEOU were positively associated with intention to use mobile application. Thus, the results imply that increasing older adults' PU and PEOU can promote their intention to use mobile application.

The purpose of this study is to investigate the effects of informational diversity-sensitive orientation on employee attitudes, focusing on the moderating effects of communication. Recently, diversity within organizations has intensified and the importance of diversity management within organizations is increasing. Diversity studies have focused on the variance of objective diversity characteristics, and have provided mixed results. In order to overcome limitations in the research, this study focuses on members' perception of diversity. To this end, the variable of informational diversity-sensitive orientation(IDSO) was used. Sample data is derived from 301 surveys of employees in firms located in South Korea. Results show that informational diversity-sensitive orientation(IDSO) had a positive effect on job satisfaction and organizational commitment. Regarding the moderating effect of communication, a positive moderating effect was exhibited only in co-worker communication, and differential influence derived from communication type. Based on the analysis results, we discuss research implications and directions for future research.

Recently, the scale and technical complexity of agricultural production has been growing. Therefore, agricultural facilities are being gradually diversified, expanded, and made more complex. To furnish Korea's agricultural industry with international competitiveness, it is thus necessary to introduce new management techniques. The PCM (procurement-construction-maintenance) information management system for agricultural facilities is established by setting up its WBS (work breakdown structure). In this study, the WBS of a facility such as facility, space, element, works, and resources is analyzed. Following this analysts, a WBS of an agricultural facility that is appropriate for the PCM information system of an agricultural facility, is proposed by deriving it from actual WBS.

Recent proliferation of building information modeling (BIM) has actively stimulated integrated utilization of geometric (graphic) and non-geometric (non-graphic) data. Nevertheless, physically and logically, linking and maintaining these two different types of data in an integrated manner requires enormous overhead efforts for practical implementation. In order to address this problem, this paper proposes a concept and structure of the object breakdown structure (OBS) that facilitates advanced BIM implementations in an automated and effective manner. Proposed OBS numbering system has secure rules for organizing graphic objects in full considerations of effectively integrating with non-geometric data (e.g. cost and schedule). It also removes repetitive linking process caused by design changes or modifications. The result of applying this concept to a housing project revealed that only 120 definitions controled over 6,000 graphic objects for full integration with cost and schedule functions.

Live commerce as a new form of service that combines live streaming service with e-commerce is gaining a growing attention from many people with diffusion of a new trend of untact economy. In this context, this research examines what leads to user satisfaction of live commerce. In especial, this research conceptualized several determinants that might affect user satisfaction of live commerce from three dimensions of users, information sources and platforms. It also tested whether those factors had influences on user satisfaction of live commerce empirically. The sample in this study was responses of 218 people in their 20s and 30s who had experienced using live commerce. They were analyzed using a hierarchical regression analysis. The findings revealed that depression and innovativeness from the dimension of users, attractiveness of show host from that of information sources, and physical affordance and perceived interaction among users from that of platforms had significant influences on user satisfaction of live commerce.

This study examined the effects of game genre, news media with differing political ideologies, and game-related information sources on gamer issue participation by performing a hierarchical regression model, using an online survey on Korean gamers (N=1,362). As a result of the study, playing specific genres of games played a positive role in gamer issue participation. The group behavior or collective action for or against game regulation reported in the liberal/moderate media acted as a mobilization cue for readers and potentially encouraged gamers to take social action. But the conservative media, which used governmental organizations and interest groups as sources of information, had a negative impact on real-life participatory behavior. The biased journalism practice of the mass media on game-related social issues influenced gamers' social and political behavior through corrective action. This study is significant in empirically analyzing the relationship between political ideology, game genre, media use, and gamers' social participation. The current research suggests the improvement of game regulation policy and the need for theoretical and conceptual expansion of game research.

This study discusses how to protect foreign knowledge workers from disasters conceptually. While their prestigious social and economic status, the knowledge workers can become vulnerable to disasters due to their nomadic lifestyle and voluntary isolation from communities where they reside temporarily. This study introduced and discussed strengths and weaknesses of various types of disaster communication networks and found the Small World Network (SWN) and the use of structural holes would be an appropriate strategy for the protection of knowledge workers. The use of mediators for disaster communication would be a strategic intervention from public and private organizations since that addresses voluntary isolation issue without restructuring existing disaster communication network.

This study aimed to distinguish categories of archival information and identify properties by their detail types, so that the various forms of architectural heritage information generated can be managed based on their attributes and characteristics. First, the specific uses of terms in the legal system were reviewed and their associated concepts specifically defined. "Architectural heritage" was defined as architecture belonging to the category of tangible cultural heritage as designated by law, and "architectural heritage archival information" was defined as all kinds of material expressed by electronic processing of the actual status for preservation and management. Next, the production status of architectural heritage archival information was reviewed in relation to the legal system. This confirmed that relevant legal systems were organized hierarchically and that various types of archival information were generated in a single project. Furthermore, it was confirmed that even archival information produced in the same form contained differing contents depending on the specific purpose and method, and that there was no classification by which to cover all archival information. Finally, it was also confirmed that detailed drawing types could be categorized according to the purpose of production and the target of the records. Based on the findings of this review, the type and properties of archival information were presented as the primary classification criteria, and the architectural heritage archival information was divided into 6 general types and 27 detailed types. Specifically, the linguistic form, dimension, temporal property, and graphic form of archival information were applied as criteria for the classification of general types, and the target, production purpose, production method of archival information, and content characteristics of archival information properties of archival information by type were comprehensively reviewed.

Given the rapid development of information and communication technology (ICT) and the deepening of the information gap phenomenon in the context of the COVID-19 pandemic, researchers and practitioners need to understand the changing perceptions of new phenomena such as COVID-19 information gap on the existing information-vulnerable population. In this study, an empirical analysis was performed with the digital information gap survey data in 2020 to understand the potential impact of COVID-19 on the information gap according to the information-vulnerable class. This study is to verify the effect of information gap, marginalized groups, gender, and major factors of information services (contents, social relations, life services, information production, networking, social participation, non-face-to-face services) on the change in perception of digital information technology after Corona. Hierarchical regression analysis was performed. As a result of the analysis, it was found that the higher the content, social relationship, life service, networking, and digital non-face-to-face service, the higher the change in perception of digital information technology after Corona. Therefore, in light of the evolving phenomenon of COVID-19, it is considered that the government needs to provide education and training to strengthen the capabilities of the information-vulnerable class in order to resolve the digital information gap.
