  • The unprecedented demands of mobile communication networks by the rapid rising popularity of mobile applications and services require future networks to support the exploding mobile traffic volumes, the real time extraction of fine-rained analytics, and the agile management of network resources, so as to maximize user experience. To fulfill these needs, research on the use of emerging deep learning techniques in future mobile systems has recently emerged; as such, this study deals with deep learning based mobile communication research activities. A thorough survey of the literature, conference, and workshops on deep learning for mobile communication networks is conducted. Finally, concluding remarks describe the major future research directions in this field.

  • The land transport industry is more important than the air transport or shipping industry. Land transport has the largest number of business and employees, and the fourth industrial revolution technology has recently infiltrated the most rapidly. In this paper, we examine the status, future prospects, and implications of the land transport industry in Korea for the past 7 years based on the statistical database and related literature. We survey the scope and characteristics of the freight truck or rail transport industry, government policies, and recent logistics industry trends. From the results of these current and forecast statistical surveys, we propose a way forward for the domestic transport business.

  • To reduce mobile network deployment costs and expand service coverage, mobile infrastructure sharing is becoming increasingly important. This paper introduces the concept and potential benefits of mobile infrastructure sharing as documented in the existing literature. Then, the current status of significant cases of mobile infrastructure sharing in major overseas countries is examined. Finally, sharing 5G infrastructure in rural areas in Korea is introduced. The Korean case is expected to complete national 5G coverage successfully without involving negative competition.

  • The purpose of this study is to investigate domestic and foreign fashion sock design trends and suggest a proposal for competitive fashion sock design developments. The methods of this study are undertaken by literature review and design trend analysis. For the design trend analysis, in the case of domestic cases, 209 pictures from 7 brands, and in the case of foreign cases, 870 pictures from 10 brands are being chosen. In terms of analysis criteria, the colors, patterns, lengths and images of both the domestic and foreign socks are being compared. As a result, among the fashion foreign socks, more than 4 colors are the most common, and dark & dark grayish, strong & deep color tones are the most popular. Also, the stylized, geometrical patterns, and casual, cute and unique images are generally used. In the case of domestic fashion socks, 2 colors are the most common with vivid, strong & deep color tones as the most popular. Furthermore the patterns are limited to geometric patterns, and the images of socks are inclined to be too casual. To enhance the competitiveness of Korean sock designs, the variety of patterns and images are essential.

  • The purposes of this study are to evaluate the research trends of articles published in the Journal of the Korean Family Resource Management Association from 1997 to 2008, and to identify the contributions as well as the inherent limitations of these articles in the field of family resource management. For these purposes, this study analyzed 3 types of research trends: research topic, research method including data analysis, and research subject. The findings of this study are as follows. First of all, the study shows that most number of researches are conducted on management subjects, followed by management practice and management theory. Secondly, regarding the frequency of the research method, the empirical researches are the most prevalent method employed by the researches, over literature or practice researches. Thirdly, it is noted there are more quantitative researches than qualitative ones. Finally, there are a lot more researches carried out on the traditional household than those of vulnerable households.

  • Objectives: The purpose of this study was to investigate the current state and trends of health-related research on foreign migrants living in Korea. Methods: Among 85 articles identified via PubMed and RISS and additional 7 articles by ancestry search, 28 were selected for the review. Two authors independently reviewed the articles using a literature review matrix and examined together the three aspects of the studies: research methods, research topics, and research results. Results: Most of the articles were published between 2005-2009, and only 3 studies used an interdisciplinary approach. Most were exploratory and there were 4 intervention studies: three of them examined the effect of an art therapy on acculturative stress and mental health among marriage migrant women. The lack of information on informed consent, approval of institutional review board, and the validity/reliability of the translated instruments were noted. Conclusions: Research is needed to examine migrants' health behaviors, the prevalence of chronic illness among migrants, and the influence of acculturation on the use of health resources, health behaviors, and health status. Researchers should be aware of ethnic issues when they work with foreign migrants.

  • This study was to find out contemporary planning characteristics of rural houses in Na-po Munhwa village by analyzing their floor plans. These results were then compared with apartment housing trends. 240 houses were built in that village, but it was only possible to collect housing data, floor plans and general building records from 102 houses, using house registers. By analyzing those data, the findings were as follows: 1) Floor plan shapes of rural houses showed a tendency to words a 'ㅋ' shape, a 3bay or a transformed 3 bay and a "room-living-room" space arrangement of a centered living room. Public spaces (L.D.K) were separately planned DK from livingroom. Living space was very open and the DK space had created visual privacy from the entrance. The Anbang (master bedroom) and living space were set to the front of the floor plan and an interior toilet was planned in them. These floor-planning tendencies were similar to trend apartment houses in urban areas. 2) Utility and Balcony spaces as a support space of kitchen were not popular features of rural houses in the Munhwa village. These results were different from urban apartment housing trends. 5) Storage space practically absent in those rural houses, and this was similar to urban the trends in urban apartment houses.

  • Background: Physical therapy has been widely studied in various fields, however, the academic trends and characteristics has not been systematically analyzed. Semantic network analysis is used as an approach for this study. Objective: To explore academic trends and knowledge system in the physiotherapy research in the Journal of International Academy Physical Therapy (J of IAPTR) Study design : Literature review Method: Semantic network analysis was conducted using the titles of 272 articles published in the Journal of IAPTR from 2010 to 2019. Results: Frequency analysis revealed following most frequently used key words; Stroke (27 times), Balance (21 times), Elder (13 times), Forward head posture (FHP, 11 times), Muscle activity (9 times).

  • Digital twins are one of the promising digital technologies used to facilitate digital transformation. Therefore, it needs to continually be developed remain relevant in industry and academia. Consolidation of research is required to create a common understanding of the topic and to ensure that future research is built upon a solid foundation. Based on a bibliometric review and a thematic analysis of 217 publications on digital twins from the past two decades, this paper creates and analyzes a visual knowledge map and proposes areas for further research. To comprehensively analyze the development trends and research trends of digital twins, we performed statistical analysis of the relevant literature on digital twins within the core collection database of Web of Science. Through our research, we have shown that the current situation, trends, and hotspots of digital twin research were analyzed via CiteSpace. This study demonstrates that research on digital twins is rapidly growing in popularity, that the output of the research depends largely on the core group of authors conducting it, and that digital twins warrant cross-domain and cross-disciplinary research pathways.
