  • The purpose of this study is to show typology of virtual world and to look out how virtual world develops especially in Korea. As paradigm changes, the scientific virtual reality and world wide web are absorbed into 3-D virtual world in Metaverse. The metaverse is the convergence of virtually enhanced physical reality and physically persistent virtual space. There are two categories of virtual world, the Ludic Virtual World which is oriented from games like MMORPGs and the Social Virtual World which is oriented from network communication system. Compared to North America and Europe, the Ludic Virtual World and game society grow and develop quickly in Korea. It's because Korean users prefer the online environment where millions of people live out a collective fantasy existence.

  • The purpose of this study is to improve robot motion control in teaching and operating the expert system/world coordinate system (TOES/WCS) constructed in the previous study. The major contribution of this study is reduction of the inaccuracy in coordinated reading and the movement time of robots in macro motion control. This study also reduces undesirable time of micro motion control by using an unit control (UC) and a micro unit control (MUC) in micro motion control.

  • This paper describes an experimental system for automatic robot programming, The SNU-ARPS (Seoul National University Automatic Robot Programming System). The SNU-ARPS generates executable robot programs for pick and place operation and some simple mechanical assembly tasks by menudriven dialog. It is intended to enable the user to concentrate on the overall operation sequence instead of the knowledge regarding the details of robot languages. To convert task specifications into manipulator motions, the SNU-ARPS uses an internal representation of the world. This representation initially consists of geometric database from CAD system and is updated at each operation step to reflect the state changes of the world.

  • Domestic construction industry (including plant engineering industry) faces severe competition with world-wide leading companies under WTO (World Trade Organization) system. To survive in this competition, domestic construction company should establish and operate standardization system efficiently. In this paper, check list is presented to prepare the efficient reliability management system in domestic construction. And then, the check list is applied in MIR(Maturity Index on Reliability) estimation item to estimate reliability management level of company quantitatively.

  • To select potent probiotics from lactic acid bacteria in Yulmoo Kimchi, an in vitro and stimulated human intestinal model system (SHIMS) test were performed. One Leuconostoc mesenteroides strain from five strains of Yulmoo Kimchi and one Lactobacillus plantarum from 12 strains of KCTC and KCCM were selected according to survival in acidic and bile salts conditions. Between the two species, Leu. mesentroides displayed higher survival activity in a SHIMS test. The strain was identified as Leu. mesentroides by 16S rRNA sequencing and was designated as Leu. mesentroides K01.

  • The introduction of the world geodetic reference system in cadastral sector can apply the international standardization of cadastral survey and can be the basis for the creation of new industries by merging with other industries based on spatial information. With the introduction of the world geodetic reference system, non-coincidence land may cause problems which are whether the cadastral record and the real estate register are not consistent, etc. This problem infringes on the protection of ownership of citizens suggested in the main purpose of 「Act On The Establishment, Management, Etc. Of Spatial Data」. We have analyzed at overlapping cases between private land and overlapping cases between national and public land and suggested institutional improvement measures to solve problems arising on the site. As a result, it will be necessary to introduce a transformation verification measure by the world geodetic reference system in order to assign a function as a cadastral records to mapping converted to the world geodetic reference system. It is also expected that the legal and institutional basis should be established for alert adjustment and positioning through verification measures. Finally, it is difficult to determine the transformation factor as the co-ordinates of common points also differ because survey results vary by work area. Therefore, it is deemed necessary to consider the requirement to use the cadastral measurement basis by the world geodetic reference system in 2021.

  • Universities are considered important actors and drivers of socio-economic development in the regional innovation eco-system. This article investigates the role Kenyan universities and research institutes play in the development of regional innovation eco-system in the context of triple and Quadruple helices. A model involving Government, Industry, Universities and Society (Public) linkages in the regional innovation eco-system and with Information and Communication Technology as an enabler is used as a framework for analysing the nature of linkages in Kenya. The article uses literature review and case study methods to examine how universities and research institutes can spur the development of the innovation eco-systems. The research question is: what is the role of Kenyan universities and research institutes in spurring innovation ecosystems? Six cases of Kenyan universities and research institutes are considered in the light of Government Policy on Science, Technology and Innovation (STI) which is underpinned in Kenyan constitution 2010. The study contributes to the understanding of how deep collaboration among universities, government, research institutes, Science Cities, local, regional, national and international players spurs the creation of world-class innovation ecosystems which can contribute to regional development in developing countries like Kenya.

  • Human history show the whole society changed rapidly and found that the momentum and foundation of such change is " the advanced technology ",which is, the advanced knowledge. The world is newly established based upon openess, spaclalization and globalization, and the each nation and company should have to adopt all the existing frames to follow the new world reality. Today is the changing period from industrial society to information society, and information technology plays a great role. As the information society moves ahead, world economy and social infrastructure will be based upon network society and various information systems will make an integrated information system. This paper presents that to establish interior design related information in the age of information with radical change of previous way of thinking, cooperative information exchange system. Also substantial and effective communication systems should be made and continuing cooperation system of interior design information area should be formulated.d be formulated.

  • Real cyberterrors are invisible and difficult to identify. Even after a cyberattack, its origin and cause are difficult to determine. Cyberterrorism results in invisible cyberwars, and it is believed that World War IV will begin with a cyberwarfare. For national cybersecurity, information on cybersecurity must be collected, shared, and disseminated. In this study, we investigate a blockchain system designed based on the World Cybersecurity Agreement. National cybersecurity information is linked to the hyperledger blockchain system network through the National Cybersecurity Center. National cybersecurity information designs and uses a secure protocol for protection; further, it is collected, shared, and disseminated to treaty countries. National cybersecurity information is shared and spread by the hyperledger blockchain system, and it uses a cyberdefense system that responds to the cyberattacks and their origin. This paper serves as a policy and legislation guideline for forming a World Cybersecurity Agreement between countries.

  • Because of many advantages of Maglev(magnetic levitation) trains, the study of Maglev technology has been accelerated rapidly throughout the world. As a results of that, German commercialized the super-speed magnetic train in Shanghai at the world-wide beginning. Japan started the first commercial service for the low speed Maglev train system in Nagoya in the world. For the commercial service of Maglev trains, signal system must be installed on the operation line and be controlled by operation control center In this paper, Maglev train operation systems of the inside and outside of the country are investigated and what is supplied for domestic Maglev train system is investigated.
