Patents in Korea, Japan and the U.S. were searched at the Korea Intellectual Property Rights Information Service (KIPRIS) of Korea Institute of Patent Information using related keywords in order to analyze the trend of patents on the usage of waste wood. Materials on a total of 77 patents in Korea, 317 patents in Japan, and 316 patents in the U.S. that had been registered as patents as of Dec. 31, 2011 were collected. Among the collected materials, the patents rejected, expired, annulled, withdrawn and waived as well as those which had little relationship with waste wood were excluded and the 71 patents in Korea, 227 patents in Japan and 216 patents in the U.S. were finally selected for analysis. In addition, the properties of the mortar which used waste wood as an alternative for a part of the fine aggregate were tested as a basic study for the usage of waste wood as a lightweight aggregate for concrete. For the test, the waste wood of the pine tree was crushed, sifted through No. 8(2.4 mm) sieve, and then dried for 24 hours at $100{\pm}5^{\circ}C$. As it is known that some kinds of tree prevent the hardening of cement when the wood is mixed with cement, the crushed waste wood in this study was dipped in the water of $20^{\circ}C$, $50^{\circ}C$, $80^{\circ}C$ and $100^{\circ}C$ and then dried up before testing the properties of the mortar to examine the effect of the preliminary treatment of crushed waste wood.

As the construction industry becomes bigger and more complicated, standardization of terms should be established between academic and industrial fields in order to accumulate and share information technology. The aim of this study is to investigate and analyze the research trends and actual usage of construction and architectural terms in Korea. For this purpose, we examined research related to construction and architectural terms by searching RISS up to August 2014. We also analyzed document types and contents of research by year. As a result, 130 research studies related to construction and architectural terms were searched. Of document types, glossary ranks the highest, followed by academic journal papers, master's theses and research reports. Research related to construction and architectural terms began in 1939, and was actively studied between the mid-1980s to the mid-1990s. Within the research, list and opinion of related construction and architectural terms are found the most frequently, followed by standardization, analysis, alteration, dictionary and wordbook, and search system of terms. Despite these efforts and research, standardization of terms has not yet been consolidated between academic and industrial fields. Therefor, we suggest six proposals in order to standardize the terms. This study is an attempt to see the trends and conditions of construction and architectural terms and to provide base-line data and an insight for future research.

With the advent of the Internet and the development of mobile digital devices such as smartphones and tablet PCs, the communication service paradigm began to shift from existing voice services to data services. Recently, as social network services (SNS) are activated and 4th industrial revolution technologies centered on ICT (Information and Communication Technologies) such as Big Data, Blockchain, Cloud, and 5G/6G are rapidly developed, the amount of shared data type and the amount of data are increasing rapidly. As the transition to a digital society begins actively, the importance of using data information, as well as the economic and social values of personal information are becoming increasingly important. As a result, they are actively discussing policies to revitalize the data information industry around the world and ways to efficiently obtain, analyze, and utilize increasingly diverse and vast data, as well as to protect/guarantee the rights of information subjects (providers) in various fields such as society, culture, economy, and politics.. In this paper, in order to improve the self-determination right of personal information on data produced by information subjects, and further expand the use of safe data and the data economy, a differentiated data trusts system was considered and suggested. In addition, the components and data trusts procedures necessary to efficiently operate the data trusts system in Korea were considered, and the non-profit data trusts system and the for-profit data trusts system were considered as a way to flexibly operate the data trusts system. Furthermore, the legal items necessary for the implementation of the data trusts system were investigated and considered. In this paper, in order to propose a domestic data trusts system, cases related to existing data trusts systems such as the United States, Japan, and Korea were reviewed and analyzed. In addition, in order to prepare legislation necessary for the data trusts system, data-related laws in major countries and domestic legal and policy trends were reviewed to study the rights that conflict or overlap with existing laws, and differences were investigated and considered. The Data trusts system proposed in this paper is a reasonable system that is expected to recognize the asset value of data in the capitalist market economy system, to provide legitimate compensation for data produced by data subjects, and further to contribute greatly to the use of safe data and creation of a new service market.

The smart-car industry has emerged as the important variable that will decide the future industrial contour of the automotive industry, together with commercialization of electronic vehicles, connected cars, infotainment, telematics, and the autonomous/self-driving car. This study analyzes the strategic position of platform companies and car manufacturers that would determine the future of the smart-car market. The findings of this study show that despite the entry barriers in industrial factors, such as economies of scale, the industrial infrastructure, and global production networks, and technical factors like exclusive head-sector information, car manufacturers may be deprived of their industrial leadership by platform companies with map and user data, big data capabilities, and user interface experience if they lag behind ICT innovation. This insight is based on the emerging importance of software and platforms, and the simplification of car structures, proven by the successful commercialization of electronic vehicles. This study complements existing studies mainly focused on technical aspects of the smart-car industry by examining the strategic dimensions of platform companies and their approach to the future smart-car market by comparing them with existing car manufacturing multinationals.

Research literatures (e.g. research report, scientific paper and thesis, published between 2001 and 2005) of 332 collected from KISTI, KISS, ARPC databases were investigated and analyzed to give an overview of domestic ginseng researches. Most of recent ginseng researches have been performed by private nonprofit institutions and individuals, which suggests that a role of public institution fur ginseng researches needed to be enlarged. In terms of research fields, cultivation and agricultural researches have been mainly accomplished in ginseng research. Cell physiology and reproductive function researches occupied large part of pharmacological studies, but clinical studies were relatively limited. Studies on general food products development have taken the main part in fields of food products including functional foods. As the result of analysis of 312 domestic ginseng patents by classifications of world international property organization (WIPO), it was categorized into food technology, medicinal fermentation development technology, fermentation technology, and agriculture-fisheries technology. This integrated overview of the widely scattered ginseng literatures shows current general research trends in Korea and will be able to suggest further needs on cultivation, studies and industralization of ginseng.

Methods that industrial spies use to smuggle core technology out are becoming more intelligent, technological, and complex, thus resulting in more serious damages. In particular, defense industries in which involve national core technology as well as institutions including labor force are industries that are in a greater need of the convergence security. Defense Industry develops, experiments, and produces defense security supplies for national security protection. Defense industry involves a number of security elements such as military secret, industrial secret, core technology labor force, defense industry supply, critical national facility, and information communication system. Defense industry security is a complex of military security and industrial security which is convergence security that integrates all security elements of defense industry. Therefore, defense industry security is a typical ideal model for convergence security. Research on defense industry security is relatively insufficient compared to research of security in other industrial fields. In order to prevent core technology of denfese industry from leaking and to protect technical professionals and institutions, research and action on defense industry security from convergence security perspective are therefore essential at this point of time.

South Korea decided to use the public safety long term evolution (PS-LTE) method to build a wireless communications network for national disaster. The move will allow all disaster management agencies, including police, firefighters and the military to use multimedia information, including videos, in addition to voice to carry out rescue operations from 2017. The Ministry of Science, ICT and Future Planning said Thursday that it adopted PS-LTE as the technology method for national disaster management system following a national policy coordination meeting last month. PS-LTE is a method integrating group communication, direction communication between terminals and independent base station function with existing LTE technology. Until now, disaster management agencies used technology that only allowed voice communication. However, transmission of multimedia information is possible using PS-LTE.
