  • The Internet of Things (IoT) is characterized as the market where various companies compete for the same consumers. Thus, there are differences in functions and performance provided by the main business area and other characteristics of the service providers. This paper investigates whether satisfaction with the service provided depends on the characteristics of the operator by using sentiment analysis of comments. To achieve this goal, word importance analysis and sensitivity analysis are conducted on 34,310 reviews of 41 applications registered in the Google Play. The review analysis was conducted at various levels, including TD-IDF (Term frequency-inverse document frequency) value of keywords, service sectors, the origin of providers, and domestic/foreign providers. The results show that users' overall assessment of IoT services was found to be low, and smart homes received relatively high reviews compared to other services, and manufacturing-based and overseas providers received relatively higher evaluations than others.

  • This study reviews empirical studies that investigated the impact of marketization of long-term care services on quality of care in Korea, England, Sweden, United States, and Japan. The trend and characteristics of marketization and regulatory system in those countries were compared. Since 2008 when long-term care insurance was introduced in Korea, we selected and reviewed empirical studies which were listed in the National Research Foundation, PubMed and Web of Science and examined the relationship between marketization and quality of care. Seven Korean, three English, two Swedish, seven American studies and one Japan study were identified and there was little evidence supporting that marketization would lead to better quality of care. Specifically, competition had no consistent relationship with quality of care while there was little evidence supporting that for-profit nursing homes tended to exhibit greater quality of care compared to non-for-profit nursing homes. The chains of for-profit nursing homes were revealed to have greater deficiencies. The findings of this review imply that improvement of quality of care may not be achieved by making for-profit nursing homes have chains. Reconstruction of nursing home markets should be needed, and the number and the proportion of public and non-for-profit nursing homes should be increased.

  • Since 2011, after beginning of the systematic study on STEAM education, South Korea has developed a number of related programs. At this point we see that this is the time to clarify the challenges. The purpose of this study is to clarify the characteristics of their education through the review of many domestic and foreign papers in order to propose the challenges of STEAM education of Korea. The results are as follows. First, the course of integration cannot be separated by the difference in superiority but should be separated in accordance with the purpose of integration. Second, curriculum integration such as STEAM education is characterized by the emphasis on horizontal linking than vertical depth fusion. Accordingly, the content knowledge and vertical linkages are inevitably weakened. In order to overcome this problem, the key concepts and features that were emphasized in the previous curriculum need to also be emphasized in STEAM training, and the comparative study on the core concept and function of each subjects should be preceded. Third, after looking upon the current situation of our country's fusion research and talent training, the limits and the challenges that need to be overcome has been suggested. Fourth, with the basis on research results, we offered an example of the approach on STEAM education which is applicable to the current situation and proposed the challenges and implications that need to be addressed in the STEAM education of Korea in educational contexts such as curriculum, teaching and learning, and evaluation.

  • This review paper presents a review of evidence on systems and technologies for recent remote sensing techniques which were applied into forest and forest related sectors. The paper reviewed remote sensing techniques that will have, or already having, a substantial impact on improving data quality of forest inventory and forest management and planning. The aim of this review is to identify, categorize and discuss Korean and international sources published primarily in the last decades. The focus on remote sensing and ICT technologies examines issues related to their opportunities, limitation, use and impact on the forestry. More specifically, this literature review has focused on laser scanning, satellite imagery, and Unmanned aerial vehicles (UAV) utilization in forest management and inventory analysis.

  • This study searched for the status of medical Systematic Review(SR) publications in Korea and elsewhere for last 10 years, closely analyzing SR research papers by co-authors of Korean librarians. Through interviews with Korean librarians participating in SR, the activities, roles, and difficulties of these librarians were identified, and the results of the interviews helped explore new ways to promote collaboration in SR research. The result of the studied showed that the number of domestic and foreign SR studies has recently increased, and the number of cases where Korean librarians participated in SR research being officially credited as a co-author or acknowledgment source was also grow. The SR librarians in the Korean medical libraries were not only search experts, data collectors, and reference writers, but also did various activities such as designing search strategies, SR search records with complete reproducibility, and DB search tutorship. To promote SR support librarians participated in the interview suggested recruiting new librarians, retraining current librarians, and reformation courses in library and information science. As it is expected that the level of information demand of users and expectations for librarians would also increase in near future, SR librarians' activities and contributions seem to offer a guideline for academic library services that the others should pursue.

  • The purpose of this paper is to examine the most recent tunnel scanning systems to obtain insights for the development of non-contact mobile inspection system. Tunnel scanning systems are mostly being developed by adapting two main technologies, namely laser scanning and image scanning systems. Laser scanning system has the advantage of accurately recreating the geometric characteristics of tunnel linings from point cloud. On the other hand, image scanning system employs computer vision to effortlessly identify damage, such as fine cracks and leaks on the tunnel lining surface. The analysis suggests that image scanning system is more suitable for detecting damage on tunnel linings. A camera-based tunnel scanning system under development should include components such as lighting, data storage, power supply, and image-capturing controller synchronized with vehicle speed.

  • Despite various treatments, there is a tendency of convicted sex offenders to recidivate by committing additional sex crimes. Especially when the offenders are diagnosed comorbidly with paraphilia and personality disorders, effective treatment is critical because this difficult condition can be harmful to their psychological well-being and the security of the communities in which these men live. The aim of this review is to examine the comorbidity of personality disorders and paraphilia in the male sex offender population. This study is highly meaningful as not only it is the first domestic research on the link between paraphilia and sex crimes, integrating the preceding data from both domestic and international research, but also as it synthesizes the studies of criminal psychology, social welfare and clinical psychology.

  • Cancer pain is a very important factor in cancer patients refractory to drop the quality of life of cancer patients. The worldwide trend is an integrated effort by both the western medicine and korean traditional medicine of treatment increases to reduce cancer pain. There are many studies related to cancer pain through an integrated medicine approach. Many study was reported that acupuncture treatment is effective for fatigue, xerostomia, insomnia, anxiety and quality of life. However, despite the practical clinical effects and various case reports of acupuncture, many still disagree about the significance of an integrated treatment of pain reduction with acupuncture. Therefore, we has identified that reduce effect of comprehensive and integrative treatment using acupuncture for cancer pain through publication review. And we evaluated effect of comprehensive and integrative treatment using acupuncture through summary of values in each publication.
