Hepatocellular cancer is a very common cause of cancer related deaths worldwide. Only 30-40% of patients present with early-stage disease open to curative treatments, such as resection or transplantation, while others can only undergo local therapies or palliative care. Various trans-arterial approaches have been used for treatment of hepatocellular carcinoma in patients who need a down-staging to liver transplantation, and who are not candidates for transplantation or radiofrequency ablation. Transarterial chemoembolization (TACE), transarterial embolization (TAE), drug-eluting beads, and radioembolization have been used for locoregional control, and have been shown to prolong the overall survival when compared with supportive care. In this review, we discuss patient selection, pre- and post-procedure imaging, techniques, safety, and clinical outcomes related to these therapies. Newer advances with future directions in various fields related to trans-arterial therapies are also discussed.

최근 스마트 폰 시장이 둔화됨에 따라 새롭게 웨어러블(wearable) 디바이스 시장이 주목을 받고 있다. 그 중에서도 가장 주목을 받고 있는 것은 착용하기 자연스러운 스마트 워치이다. 그러나 이러한 스마트 워치는 한편으로는 작은 화면으로 불편함은 없는 지, 손목시계를 착용하는 사람만 착용하는 것은 아닌지에 대한 우려의 목소리를 받고 있다. 따라서 본 연구는 스마트 워치가 미래 웨어러블(wearable)시장에서 보편화되기 위해 필요한 요소들에 대해 알아보고자 한다. 우선 현재 스마트 워치 인터페이스가 가지는 특징은 무엇인지 살펴보기 위해 스마트 워치 인식 방법, 홈 화면 인터페이스 디자인, 주요 콘텐츠 디자인 3분류로 나누어 이를 알아보았으며 이를 토대로 미래에 스마트 워치가 필요한 요소들에 대한 근거를 마련하였다. 여기에는 2가지 제스처 인식 방식의 결합, 홈 화면 인터페이스 디자인을 위한 효용성 연구, 이용자별 특성에 맞는 주요 콘텐츠 디자인 연구가 해당되는데 이러한 결과는 미래의 스마트 워치가 나아가야 할 방향에 대해 중요한 가이드라인 역할을 수행할 것이다.

최근 물류 및 유통분야에서 혁명을 불러일으킬 것으로 예견되고 있는 RFID시스템이 국내의 건설산업 환경에도 큰 영향을 끼칠 것으로 예상되고 있다. 이미 $4\~5$년 전부터 국내 대형프로젝트에 바코드시스템을 활용한 노무인력관리 및 주요자재의 물류관리에 활용된바 있으나 바코드시스템이 갖고 있는 한계성으로 인해 건설현장에 그다지 성공적으로 정착하지 못하였다. 이를 극복하기 위한 한 방법으로 RFID시스템을 건설현장에 적합하게 개발 및 시범적용 해보았으며 본 연구를 통해 건설현장에 RFID시스템을 어떻게 적용을 하였고 어떠한 성과를 거두었는지에 대해 조사해 보았고, 향후 이러한 RFID시스템을 통해 적용 및 발전 가능한 방향에 대해 제시해 보았다.

The outbreak of a recent strain of Coronavirus, known as 'COVID-19', has spread sharply from China across the globe, resulting in a dramatic recession in the global economy. This uncertainty has therefore negatively influenced the business perspective and the various formulated strategies that may not considered such [extreme] circumstances. Using baseline analysis and archival data, this paper reports some of the major implications of COVID-19 on global business and strategy and puts forward suggested research agenda as potential future directions for organizations. In order to survive and remain sustainable, this paper argues that businesses need to revisit their strategies during current COVID-19 crises from three perspectives, including supporting human resources financial commitment, forming cross-functional teams and connecting with their supply chains, as well as investing in corporate social responsibility and doubling down efforts with regard to partnerships. The study also represents a preliminary analysis to the implications of COVID-19 on the business and strategies across the globe and is considered the first such in the field of business, as to date all research papers on COVID-19 have been published in medical-related journals. Directions for future research are also proposed at the end of this study.

Community building has been carried out from around the year 2000 by various statutes and government policies in Korea. This study suggested direction of the future for rural community building as surveyed cases of completed four villages in Gurye-county. In order to achieve this study's objectives, investigated previous studies and interviewed 75 person's residents in cases villagers. The target villages are Sangsa, Omi, Chamsaimigol and Artists village. As survey results, four villages utilized local resources, most of villages were focused perform hardware. On the other hand, Chamsaimigol was parallel software. In addition, communities didn't form and not agree with concept of community building as culture, education, welfare, etc., also didn't creation the case of village income. but active village as base development. Therefor, proposed the point to education, culture and welfare, base development and generating of income as directions for future rural community building. These directions are consistent with the concept of community building and the goal that improve the quality of life of residents ultimately through community building.

Medical imaging techniques have evolved to expand our ability to visualize new contrast information of electrical, optical, and mechanical properties of tissues in the human body using noninvasive measurement methods. In particular, electrical tissue property imaging techniques have received considerable attention for the last few decades since electrical properties of biological tissues and organs change with their physiological functions and pathological states. We can express the electrical tissue properties as the frequency-dependent admittivity, which can be measured in a macroscopic scale by assessing the relation between the time-harmonic electric field and current density. The main issue is to reconstruct spectroscopic admittivity images from 10 Hz to 1 MHz, for example, with reasonably high spatial and temporal resolutions. It requires a solution of a nonlinear inverse problem involving Maxwell's equations. To solve the inverse problem with practical significance, we need deep knowledge on its mathematical formulation of underlying physical phenomena, implementation of image reconstruction algorithms, and practical limitations associated with the measurement sensitivity, specificity, noise, and data acquisition time. This paper discusses a number of issues in electrical tissue property imaging modalities and their future directions.

Research and technology has been transforming the agriculture to agribusiness which encompasses all operations with all the connections from faming per se, to manufacture & distribution of production supplies and farm commodities. Further, with the revolutionary development of information technology in the last two decades, we cannot talk about agribusiness process alone without considering the information technology embedded in the artifact, process, and structure. Despite the emergence of precision agriculture (PA) which is supported by IT based innovations which can not only improve efficiency in farming operations but also contribute to environmental sustainability, the adoption of IT among farmers and in agriculture industry are rather low than expected. Thus, Korean government has been seeking to converge IT into food, agriculture, forestry and fisheries to improve the competency of the agribusiness, and much progress has been made. This paper investigated the status quo of the current IT convergence with Food, Agriculture, Forestry and Fisheries in Korea, and further proposed future policy directions.

Satellite-based land surface temperature (LST) has been used as one of the major parameters in various climate and environmental models. Especially, Moderate Resolution Imaging Spectroradiometer (MODIS) LST is the most widely used satellite-based LST product due to its spatiotemporal coverage (1 km spatial and sub-daily temporal resolutions) and longevity (> 20 years). However, there is an increasing demand for LST products with finer spatial resolution (e.g., 10-250 m) over regions such as urban areas. Therefore, various methods have been proposed to produce high-resolution MODIS-like LST less than 250 m (e.g., 100 m). The purpose of this review is to provide a comprehensive overview of recent research trends and challenges for the downscaling of MODIS LST. Based on the recent literature survey for the past decade, the downscaling techniques classified into three groups-kernel-driven, fusion-based, and the combination of kernel-driven and fusion-based methods-were reviewed with their pros and cons. Then, five open issues and challenges were discussed: uncertainty in LST retrievals, low thermal contrast, the nonlinearity of LST temporal change, cloud contamination, and model generalization. Future research directions of LST downscaling were finally provided.
