The purpose of this study is to present the direction of improving the Korean Government 2.0 services by evaluating the quality of the service and analyzing its effects on user satisfaction. Recently, on the extension of e-government, Government 2.0, which is the government service combined with Web 2.0, has emerged as a new paradigm. However, there are very few studies on the impact of Government 2.0 on general society and industries. Especially, there is little or no practical analysis and evaluation for the quality of Government 2.0 service. Because the service quality is typically used as the leading indicator of user satisfaction, this study applies it to the Government 2.0 for the validation of the existingtheory in a particular subject. The service quality was measured by the tangibles, reliability, responsiveness of revised SERVQUAL, the efficiency and security of the E-S-QUAL. Inconclusion, this study has empirically significant implications for providing a theoretical foundation for measuring the quality of the Government 2.0 service.

This paper examined how the millennial generation consumes mobile news through social networking sites with regards to user patterns, preference topics and news values, and whether news topics and news values may influence their overall mobile SNS news consumption and interactivity. The findings show that more than 2/3 of respondents consumed mobile SNS news at least once everyday for 30minutes to one-hour. Male millennials tended to use Facebook and Kakao-talk more than female. While the portal site was the most accessed channel for consuming mobile news, SNS was the second, more than the combined use of national daily papers, TV, and internet newspapers. The respondents' demographic characteristics and news topics also affect the form and degree of news interactivity. With regards to their preferences and prioritization of news values, millennials tend to perceive 'impact' and 'usefulness' as being most important, despite the differences of their demographic characteristics. They also preferred those news values most. There were significant differences in terms of preferred news topics according to the demographics' characteristics.

While evolving information-oriented society provides a lot of benefits to the human life, new types of threats have been increasing. Particularly, cyber terrorism, happen on the network that is composed of a computer system and information communication network, and the mean and scale of damage has reached a serious level. In other words, it is hard to locate cyber terror since it occurs in the virtual space, not in the real world, so identifying "Who is attacking?" (Non-visibility, non-formulas), or "Where the attack takes place?" (trans-nation) are hard. Hackers, individuals or even a small group of people, who carried out the cyber terror are posing new threats that could intimidate national security and the pace and magnitude of threats keep evolving. Scale and capability of North Korea's cyber terrorism are assessed as world-class level. Recently, North Korea is focusing on strengthen their cyber terrorism force. So improving a response system for cyber terror is a key necessity as North Korea's has emerged as a direct threat to South Korean security. Therefore, Korea has to redeem both legal and institutional systems immediately to perform as a unified control tower for preemptive response to cyber terrors arise from North Korea and neighboring countries.

Reading and writing in the past make noble significance in 'narration', in other words, in 'the creation of narration', through the process of 'recording'; but in the modern times, it engenders controversies over narration and linearity. In other words, reading/writing in digital era, is devalued as the simple arrangement of test or the connection of vast information without narration nor linearity. However, the reading/writing through text and hypertext reading is not the phenomenon which should be criticized because of the lack of narration or linearity-not only the lack of narration and linearity -, a process of social and cultural transition; it should be revalued as a result. The change of reading and writing methods will inevitably accompany the layers, status, significance and value of the contents; thus it makes more sense, when the reading and writing methods in digital contents are approached as new pop culture phenomenon. This is the "The prose of everyday life", based on pop culture and "The society of Conversation", based on communication; proposed 'Digitelling' ; this is the reason why we should pay attention to the digital contents, created infinitely by the citizens of the world, as new mass-culture phenomenon.

Global commerce is apparently here to bind Korean firms as well as Koreans. The advertising, buying and selling of goods and services recognizes no borders. As a result, enforcing territorially based trademark rights has become ever more challenging. Remote trademark owners who peacefully coexisted in a time before the internet and increasing globalism are now bumping heads. The internet also has made it easier for unscrupulous operators to deceive consumers and divert customers from established businesses by misappropriating trademarks on web-sites and in domain names. U.S. federal courts have been willing to help American businesses halt trademark infringements that reaches outside the United States. This is particularly true for e-business, via the internet, and the trend toward enforcement seems to be in favor of the trademark owner. This article discusses this trend as well as the extraterritorial enforcement of trademark rights by U.S. courts under the Lanham Act. It also offers suggestions for protecting valuable trademark rights worldwide. This paper will contribute to global Korean firms and Koreans who carefully read arguments in this valuable literature.

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.

Recently Korea affected by the US and China trade wars, has been stagnant in the global trade market. However, the global e-commerce market is growing and emerging with new trade opportunity. The purpose of this study is to derive factors of the execution of cross border electronic commerce in the global e-commerce market and to grasp the effects of these factors on firm performance and ultimately to provide policy implications for export expansion. For this purpose, we conducted a literature review to derive the factors for firm performance in the global e-commerce market. Subsequently, conceptual research model and research hypotheses were estabilished, and empirical analysis was conducted through questionnaires. As a result of the empirical analysis, trust and ICT capability have a positive effect on firm performance, and the impact of trust on firm performance depends on the level of dispute settlement. However, ICT capability does not affect firm performance. This study differs from previous studies in that it considered global e-commerce from the perspective of the enterprise and examined factors for firm performance.

Nowadays, Light railway system is attracted public attention as solution for metropolitan traffic congestion. But it is difficult to decide an appropriate light railway system. It is especially hard in the Seoul metropolitan to decide an appropriate system, because there are many factors that must considered. So we research application status of light railway system that is scheduled or promoted in the Korea and the foreign nations. And we selected systems by types of city. In this paper, we divided into 6 types of city through factor analysis and cluster. And we considered various factor such as technology, transportation, environment etc that used previous research and feasibility study. To determine the priority among the factors, AHP(Analytic Hierarchy Process) was applied as a method for multi-standard decision method.

Federated Learning (FL) has emerged as a potent methodology for decentralized model training across multiple collaborators, eliminating the need for data sharing. Although FL is lauded for its capacity to preserve data privacy, it is not impervious to various types of privacy attacks. Differential Privacy (DP), recognized as the golden standard in privacy-preservation techniques, is widely employed to counteract these vulnerabilities. This paper makes a specific contribution by applying an existing, task-specific adaptive DP mechanism to the FL environment. Our comprehensive analysis evaluates the impact of this mechanism on the performance of a shared global model, with particular attention to varying data distribution and partitioning schemes. This study deepens the understanding of the complex interplay between privacy and utility in FL, providing a validated methodology for securing data without compromising performance.

The study aims to analyse whether Korea and Taiwan have reduced the elderly poverty effectively through income transfer system in a comparative perspective. It covers 12 Western welfare states and 2 East Asian welfare states(korea and Taiwan). Utilising Luxembourg Income Study(LIS) datasets, empirical analyses focus on old-age income mix and poverty reduction effects of income transfer. Major findings are as follows. Frist, whilst public transfer income takes a major part in old-age income mix in Western welfare states, Korea and Taiwan reveal genuine mixed states - i.e., the relative proportion of private transfers and market income are high. Secondly, public transfers have effectively reduced the old-age poverty in Western welfare state. However, thirdly, those effects are still limited in Korea and Taiwan. Rather, the poverty reduction effects of private transfers are relatively high. Based on the empirical findings, the study suggests future research agendas and policy implications.
