In modern society, cultural heritage has played a role in constituting national identity. The Cultural Heritage Education Project started in the 2000s by the Cultural Heritage Administration was also aware of the issue of sustainable development and cultural diversity as major cultural issues at the time. However, the main purpose of previous cultural heritage education was to foster national identity. The Cultural Heritage Administration has executed cultural heritage education programs since 2006. The education program of the cultural heritage teacher visiting the school, the project to designate a cultural heritage school, and an education program to experience cultural heritage at an archaeological site were carried out. In the 2010s, the theme of cultural rights and enjoyment of cultural heritage in life was raised as an important issue. Cultural heritage education had to accept the 'new meaning of cultural heritage', 'cultural rights', and 'learnercentered education'. In this context, the local cultural heritage education project started. The region is a space where various identities are reconstructed. However, local cultural heritage education itself cannot realize cultural heritage enjoyment in life. Therefore, it is necessary to seek cultural heritage in life through the various efforts of local cultural heritage education.

This paper concerns the cultural tourism and the importance of cultural interpreters. Globalization has become a key word of 21st century, so the volume of tourists has been increasing. Furthermore, as the Korean wave has expanded to the world, more people are interested in Korea and Korean culture, and we observed the obvious increase of tourists. International tourists visit Korea with a variety of purposes, and their travel types are also diversified. This paper analyzes tourists' behavior based on the data provided by KNTO and briefly examines the cultural interpreters in 5 major organizations. Then considering the specific roles of the guides based on the Cohen (1985) and Lee (2011), I propose that the government should give more focus on the professional foreign language speaking interpreters for culture. As for an alternative to the present volunteering system for foreign languages, I strongly suggest multi-culture families or international students staying in Korea, for the wiser use of their abilities, their easy adaptation to the new world, and the peaceful coexistence.

This paper presents a design of low power CMOS LNA(Low Noise Amplifier) for 2.4 GHz ZigBee applications that is a promising international standard for short area wireless communications. The proposed circuit has been designed using TSMC $0.18{\mu}m$ CMOS process technology and two stage cascade topology by current reuse technique. Two stage cascade amplifiers use the same bias current in the current reused stage which leads to the reduction of the power dissipation. LNA design procedures and the simulation results using ADS(Advanced Design System) are presented in this paper. Simulation results show that the LNA has a extremely low power dissipation of 1.38mW with a supply voltage of 1.0V. This is the lowest value among LNAs ever reported. The LNA also has a maximum gain of 13.38dB, input return loss of -20.37dB, output return loss of -22.48dB and minimum noise figure of 1.13dB.

Recently, the processing and utilization of big data, which is generated by the spread of smartphone, SNS, and the internet of things, is emerging as a new growth engine of ICT field. However, in order to utilize such big data, De-identification of personal information should be done. De-identification removes identifying information from a data set so that individual data cannot be linked with specific individuals. De-identification can reduce the privacy risk associated with collecting, processing, archiving, distributing or publishing information, thus it attempts to balance the contradictory goals of using and sharing personal information while protecting privacy. De-identified information has also been re-identified and has been controversial for the protection of personal information, but the number of instances where personal information such as big data is de-identified and processed is increasing. In addition, many de-identification guidelines have been introduced and a method for de-identification of personal information has been proposed. Therefore, in this study, we describe the big data de-identification process and follow-up management, and then compare and analyze de-identification methods. Finally we provide personal information protection issues and solutions.

메타버스 서비스란 '가상', '초월' 등을 뜻하는 영어 단어 '메타(Meta)'와 우주를 뜻하는 '유니버스(Universe)'의 합성어다. 현실세계와 같은 사회.경제.문화 활동이 이루어지는 3차원의 가상세계를 의미한다. 코로나 상황 속에서 비대면 소통의 수단 중 하나로 주목받으며 업무, 친목, 각종 행사 등 다양한 분야에서 활용되고 있다. 2022년 신년 사업 계획에서 메타버스 단어가 들어가지 않은 곳이 없다고 한다. 그만큼 핵심 키워드로 떠오르고 있다. 즉, 메타버스는 현실을 초월한 가상의 세계로 스마트폰, 컴퓨터 등 디지털 미디어에 담긴 세계를 뜻한다. 세상은 점차 바뀌어 가고 있다. 글로벌 통계 전문 업체 스태티스타는 2021년 307억 달러(약 35조 3265억 원) 규모이던 메타버스 시장 규모가 2025년에는 약 2969억 달러(약 341조 6428억 원)까지 커질 것으로 예측하였다. 현재 시장에서 통용되고 있는 메타버스에 대한 정의는, '현실세계의 사회·경제·문화적 활동이 유사하게 실현되거나, 현실에서 제공하지 못하는 경험을 제공하는 3차원 디지털 가상공간'으로 요약된다. 2021년의 메타버스는 더 이상 상상의 영역이 아니며, 현실세계 영역으로 침투하고 있는 것이다. 현실세계와 연결되는 가상세계, 실재감을 느낄 수 있는 가상공간이 점점 현실이 되어가고 있다. 1990년대 처음으로 등장한 메타버스 개념이 2020년대에 재부상 하였는데, 과거의 메타버스보다 몰입감과 실재감 있는 경험을 제공할 수 있는 XR 기술의 결합에 대한 기대감 때문이다. 지나온 30여 년간 메타버스가 뜨거운 주목을 받게 된 이유는 기술의 발전에 있다. 초고속인터넷 5G 상용화와 더불어 6G 출현, 가상현실, 증강현실이 일상에 스며들었기 때문이다. 이러한 기술 발달은 현실세계의 물리적 객체와 가상의 객체가 상호 작용할 수 있는 혼합현실까지 발전시키는 촉매제가 되었다. 여기에 지난 2년 동안 전 세계를 강타한 코로나19로 인해 비대면, 온라인 서비스가 확산되면서 메타버스는 개념이 아닌, 우리 일상의 한 부분으로 인정받게 되었다. 현재 우리 사회는 과거에는 불가능하다고 생각했던 사회적 거리두기, 재택근무, 온라인 수업 등을 진행하면서 이렇게도 사회가 돌아갈 수 있다는 것을 점차 느껴가고 있다. 더불어 현재 코로나로 인해 멀게만 느껴졌던 메타버스 세계를 반강제적으로 경험하고 있기도 하다. 이처럼 본 고에서는 최근에 나타난 메타버스를 이해하고 방송미디어(계)와 접목된 유형과 기술적, 서비스 사례를 파악하고, 주요 기업들의 추진 방향, 주요 시사점 및 결론으로 도출해보았다.

In this paper, we propose an efficient network virtualization model in cloud computing environments. Virtualization is a key technology for the implementation of service-oriented architecture. It is a standardized framework that can be reused or integrated with changing business priorities through a IT infrastructure. Network virtualization has emerged as an important technical issues of the future virtualization technology in Internet. The concept of network virtualization and related technologies stay in ambiguous status since network virtualization is in its early stage. Thus, we propose a network virtualization model for cloud environment by analyzing the existing network virtualization technologies.

Characteristics of laminar lifted names in coflow jet with various coflow velocities have been studied experimently. USlI1g the fuel nozzle with d=0.254 for the pure propane, liftoff heights are fitted by using power equation with jet velocity. As coflow velocity increases up to 60 cm/s powers of fitting equation steeply decrease. From the result of numerical analysis using the FLUENT, the stoichiometry contour and the axial velocity nondimensionalized by initial jet velocity along the stoichiometry contour are changed with variations of coflow velocities, The change of axial velocity along stoichiometric contour is more sensitive than that of stoichiometric contour, For this reason, powers of fitting equation for liftoff height with jet velocity decreases with the increase of coflow velocity. Using the fuel nozzle with d=4,35 mm for the highly diluted propane by nitrogen, the liftoff height increases with the increase of coflow velocity when coflow velocity is less than the maximum value of initial jet velocity. But when coflow velocity is faster than that, the liftoff height decreases with the increase of coflow velocity.

오늘날 기업 경영 환경은 더욱 복잡해지고, 국가간.지역간 통합 경제 체제 형태로 변화하고 있다. 정보 기술과 텔리커뮤니케이션의 결합에 따른 급속한 발전은 국가간.지역간 경계를 넘어 다국적 기업, 더 나아가서는 범세계적 기 업으로 글로벌(global) 기업을 출현시켰다. 경영 환경의 빠른 변화의 추세 속 에서 경쟁 우위를 지키기 위해서는 이러한 변화를 적절히 수용하고 적응할 수 있는 조직이 필요하였다. 기존의 MIS 관점으로는 환경 변화에 적응 할 수 있는 혁신적인 조직으로 변화시키는 데는 한계가 있었고, 이에 따라 BPR 이 대두되었다. BPR실행에 있어 성공뿐만 아니라 많은 실패도 겪었다. BPR 실행에는 많은 자금과 인력, 시간이 투자되기 때문에 실패의 손실은 기업에 게 큰 타격을 가져다 줄 수 있다. 대부분의 BPR의 실패 원인은 사회적 측면 을 고려하지 못한 데 있다. 정보 기술을 이용하여 프로세스를 급진적으로 재 설계 하였지만, 운영 주체인 구성원의 저항감이나 조직의 문화에 대한 고려 를 하지 못하였다. 그러므로 BPR을 수행함에 있어 사회적 측면과 기술적 측 면을 동시에 고려하여 적용한다면 오류나 실패 요인을 감소시킬 수 있다. 따 라서 요즈음 새로이 부상하고 있는 사회.기술적 시스템 접근법은 성공적인 BPR 실행을 위한 대안이 될 수 있다.
