  • This study aimed to investigate the extent that users participated in Facebook of U.S. state archives and the types of user responses to posts on the Facebook. For the purpose, data created between August 1st and September 30th in 2016 were collected from Facebook continuously operated by 27 state archives. The extent of user participation was measured based on the number of user comments, the number of unique commenters, and the average number of comments per post. According to the measures, top 10 Facebook of state archives were selected. Out of these, Facebook of Ohio (1st), Florida (5th) and Arkansas (10th) state archives were chosen to collect 687 user comments and 132 posts. The analysis showed that comments regarding users' emotional opinion and judgement, adding explanations to a post, and sharing personal stories occupied a large portion. Interactions among users or between a user and an archivist were also identified. With regard to posts, those for sharing information/knowledge of records held in archives were identified as a high percentage. The study suggested that archives should collect and present historical information and related records connected to users' lives, examine methods for effective communication with users via social media and facilitate publicity and outreach services of archives based on shaping and maintaining online user community through social media.

  • Food safety management should be based on scientific evidences. FAO and WHO presented risk analysis as one of four principles in food safety management. WTO also admits the self safety regulation only when it is made on the basis of risk assessment. Without scientific analysis, tracing and eliminating the cause of food poisoning is impossible. Research and development plays a key role to produce scientific evidences. The Korean government ran over 40 programs in 11 agencies from 2008 to 2010. However, there is no statistics on food safety R&D at present. In this research, food safety projects conducted from 2008 to 2010 are listed up by means of analysing National Science and Technology Information Service (NTIS). The analytical criteria are the name of programs, national standard classification of science and technology, and keywords. As result, Korea Food and Drug Administration, Ministry for Food, Agriculture, Forestry and Fisheries, and Rural Development Administration play major role in the food safety R&D. The portion of more than one year projects should rise up in order to achieve the data for risk assessment, which is strongly required to improve. Besides, the research should be deeper so as to publish more SCI papers. The R&D portfolio should be changed in direction to raise up the portion of biological hazards such as norovirus. In order to do so, a large number of food safety programs should be emerged. The categories of food safety management and the hygiene/quality management of the agricultural and livestock products in the national standard classification of science and technology should be emerged because they are set up reflecting agencies' interests in spite of few differences between them.

  • Nowadays, novel and innovative technology including 3D printers, internet of things (IoT), and wearable devices are rapidly emerging. As we must constantly keep up with the most recent trends, words like convergence, multidisciplinarity, and design revolution indeed define society today. Due to the expansion of such diverse technological, industrial, and academic convergence trends, the role of design is becoming evermore essential in development of products as well as creative services. Even the government is pushing towards a 'creative economy' by encouraging ICT convergence to create novel industries as well as advanced jobs. In order to adapt flexibly to such changes in global trends, a solid academic curriculum centered around 'ICT+Design' must be developed. In the current research, we analyzed various literature and benchmarked the major universities both domestic and foreign. Also we utilized a survey-based approach against subjects who are experts or design specialists working in environments related to industry and research. In our proposed integrated ICT+Design educational curriculum, students familiarize themselves with design perspectives and methodology to creatively carry out the course. Moreover, experts from design and ICT came together in an act of 'Radical Collaboration' in which they shared their unique 'Design Thinking' in order to promote understanding and cooperation. Furthermore, industry experts have also taken part as mentors in order to create a workplace-oriented course with various integrated projects. Most importantly, the course was designed so that in addition to research, students can really get hands-on with their ideas in the creativity-integrated workplace.

  • With the growth of aging population in Korea, a better care of chronic and other degenerative illnesses is urgently needed. Evidences suggest that this can be achieved through incorporating a wide range of care options, expanding beyond medical interventions. The aim of this study is to analyze the distribution of publically funded research to understand if the Korean research and development funding system matches various approaches and purposes to successfully tackle the chronic care needs of an aging society. We complied the list of funded projects to be analyzed by searching the National Technical Information Service database with key words such as aging society/senescence, chronic diseases, disability, and health promotion. Most projects were based on the biomedical approach with the purpose of establishing the etiology and clinical (treatment) interventions. Health promotion projects showed a distinctive distribution with more percentage of projects based on psycho-behavioral approaches while research on chronic diseases predominantly biomedical. It would be necessary to diversify publically-funded research projects to develop effective and efficient care technologies for the future.

  • Mega-corporations are emerging as a result of M&As (mergers and acquisitions) in the logistics industry. The global logistics market has progressed in a continuously competitive manner. Global logistics corporations provide integrated set of services, from production to disposal in order to manage the process efficiently throughout the diverse regions of the world. To advance into an total integrated logistics provider, the corporation must have professional knowledge in logistics and information technology which are necessary to deliver effective integrated logistics solutions. The government has integrated the logistics corporations both horizontally and vertically with the aim to foster logistics corporations possessing global competitiveness. Six years have passed since the implementation of the comprehensive (total) logistics industry certification system in pursuit of making Korea the hub for the Northeast Asian logistics market. This study compares and analyzes the efficiency of nine mega integrated logistics providers by applying the CCR model and BCC model. Each of the nine corporations is subject to certification as integrated logistics corporations. In Korea, nine corporations are certified individually as integrated logistics corporations out of the 31 logistics providers. The analysis showed that the Glovis was the most efficient integrated logistics provider reaching 100% in efficiency and displayed the highest efficiency for six consecutive years from 2005 to 2010. The study also found that the Glovis will be able to maintain 100% in efficiency rate, even though the input are increased over six times as many as those of 2010.

  • The purpose of this study is to understand spatial economic inequalities under the framework of the dynamics of economic spaces in relation to the four global megatrends: globalization, knowledge-based economy, information society, and the service world. The international inequalities in East Asia, as well as inter-regional inequalities within Japan, Korea, and Thailand were analyzed. The variables related to the four megatrends, as a whole, have clearly explained the variations in international inequalities in East Asia, as well as the inter-regional inequalities within a nation. The individual impacts of the variables on spatial inequalities are, however, significantly different depending on the spatial scale of analysis and national characteristics. Overall, there has been a convergence trend of international per capita GNI (Gross National Income) in East Asian nations, while both divergent and convergent trends are evident at the regional scale within a nation. Two global oil crises in the 1970s and the East Asian financial crisis in the late 1990s resulted in the discontinuity of the general convergence trend, and have led to the increase of international and inter-regional inequalities in economic activities. This suggests that although the effect of the global crisis differs in each country, in general, the economies of peripheral countries and regions are more vulnerable during a global economic crisis.

  • Currently the IoT (Internet of Things) environments and related technologies are being developed rapidly through the networks for connecting many intelligent objects. The IoT is providing artificial intelligent services combined with context recognition based knowledge and communication methods between human and objects and objects to objects. With the help of IoT technology, many research works are being developed using the C-ITS (Cooperative Intelligent Transport System) which uses road infrastructure and traveling vehicles as traffic control infrastructures and resources for improving and increasing driver's convenience and safety through two way communication such as bus-only lane and license plate recognition and road accidents, works ahead reports, which are eventually for advancing traffic effectiveness. In this paper, a system for deciding whether the traveling vehicle is possible or not to drive on bus-only lane in highway is researched using the lane and number plate recognition on the road in C-ITS traffic infrastructure environments. The number plates of vehicles on the straight ahead and sides are identified after the location of bus-only lane is discovered through the lane recognition method. Research results and experimental outcomes are presented which are supposed to be used by traffic management infrastructure and controlling system in future.
