Managing students' data is a high prioritized duty of the university administration since most of the school affairs are proceed based on that database. Universities have invested in IT assets such as servers, storage, database, and networks. However, continuing investment in IT infrastructure is impossible due to limited budget and rapid changes in the educational environment. As cloud computing diffuse, universities are trying to reduce costs and improve efficiency by increasing server utilization, unlike when physically investing. We designed a hypothetical academic information management system based on cloud computing by utilizing the advanced server virtualization technology. This administrative cloud system allows universities to improve the availability of the system with low cost. The system demonstrates its flexibility of using data resources and immediacy of resumption.

The method of operating a game could determine the psychological distance between the player and the game character, and thus, in the Virtual Reality, players' control methodologies are important to enhance their immersion. This study has the objective of examining the difference in games according to the method of operation based on the player's movements. This study researched the effect of the method of operating movement conforming to the movement of the character and the physical operation of the body on forming game experiences for the player. The result of performing an experiment increased reality for the game player through a controller in the shape of the actual control, to increase focus in the game. As so, game play through movements, including actual movements by the player displayed to enhance game satisfaction. In the part of media remediation field, Game can be defined as media which has their own unique hypermediacy. Especially, in the motion based game, players' movement mediates players and the game, therefore, players' movement could make players' experience augmented or immediate in accordance with the characteristics of movements. Even though sports and dances genres of motion-based games are common, RPG or adventure genres are rare. It can be explained that the characteristics of the action have been explained in the immediacy. In a game of fantasy, which is difficult to experience in real-life situations, the nature of the player's motion can increase the immersion of the game, which can contribute to utilization of players' motion and experience design in the various genres and suggestion of grounds theory. In addition, through this study, it is able to design motion-based games of various genres.

삼면이 바디인 우리나라의 지리적인 요인으로 해양은 많은 자원인 동시에 중요한 교통수단이 되어 왔다. 뿐만 아니라 현재는 모든 무역이 해상을 통해 이루어지고 있으며 98%이상을 차지하고 있다. 그에 따른 안전관리가 더욱 구체화 되어야 한다. 본 논문에서는 현재의 우리나라 해상안전 통신망의 관리체계를 살펴보고 수색·구조 통신망 시스템에 대해서 연구하고자 한다.

This study examines how consumers' intention to use a curbside pickup responds to the COVID-19 vaccination rates. With our first survey conducted in March 2021, we find that a low (high) vaccination rate is associated with consumers' high (low) intention to maintain contact avoidance and their high (low) anticipation for shipping delays. Heightened contact avoidance and anticipation for shipping delays may encourage consumers to use a curbside pickup. Our results also show that when a product is needed immediately, and a consumer expects shipping delays, s/he is more likely to use a curbside pickup. However, with our second survey conducted in November 2021, we find heterogeneous consumer responses to the vaccination rates. Specifically, consumers' political affiliation moderates the relationship between the vaccination rates and their intention to maintain contact avoidance. The association between the vaccination rates and the anticipation for shipping delays is also weakened compared to March 2021. Our empirical results illustrate how consumers' intention to use a curbside pickup emerges and changes amid the COVID-19 pandemic.

본 논문은 '정보보호학회논문지'의 참고문헌을 계량서지분석과 사회네트워크분석 방법을 사용하여 학술지와 학술대회의 인용 현황 및 패턴에 관한 비교분석 연구를 수행하였다. 인용 현황 분석결과, 참고문헌에서 학술대회의 비중이 학술지를 약간 상회하며, 약 80%가 해외 출판물로 한국 연구자들의 높은 해외 출판물 의존성이 확인되었다. 인용나이 분석 결과, 즉시인용률이 높아지고 반감기는 길어지며 인용절정기는 짧아지는 경향을 보였다. 특히, 국내 출판물의 즉시인용률이 높고 해외 출판물의 반감기가 더 느리게 나타났다. 또한, SCOPUS 학술지 및 ICORE 학술대회 식별과 주제분류를 매핑하여 분석한 결과, 학술지 인용문헌은 컴퓨터과학 (32.3%), 공학 (23.5%), 수학 (16.7%), 사회과학 (12.8%)를 포함한 기타 연구분야 (25.6%)로 구성되었으며, 학술대회 인용문헌은 'Cybersecurity and privacy' 분야의 비중이 가장 높은 가운데 최근에는 'Computer Vision and Multimedia Computation' 및 'Machine Learning' 분야의 인용 증가세가 큰 것으로 조사되었다. 출판물 동시 인용 네트워크 분석 결과, 학술대회 그룹이 학술지 그룹보다 연결 중심성 평균값이 높고 해외 출판물 그룹이 국내 출판물 그룹보다 더 높았으며, 문헌 유형 간의 동시 인용 빈도는 학술지 내에서 34.3%, 학술대회 내에서 28.8%와 비교하여 학술지와 학술대회 간에서 36.9%로 가장 높게 나타났다. 또한, 동시에 인용된 출판물들과 이들의 연구 분야에 대한 연결 구조를 탐색할 수 있는 네트워크 시각화 지도를 제시하였다. 본 연구의 결과는 국내 정보보안 연구 분야가 학술지와 학술대회 문헌을 균형 있게 활용하고 있으며, 이들 간의 상호보완적 관계를 통해 발전하고 있음을 시사한다.

최근 교육현장에서 학습에 모바일을 사용하고자 하는 아이디어는 모바일의 이동성, 현장성, 휴대성, 시성, 학습정보 접근의 용이성이라는 장점에서부터 시작된다. 특히 안드로이드폰에서 구글맵 API와 GPS를 기반으로 현재 위치의 정보(지리 및 문화관련 사진과 텍스트 등)를 공유할 수 있는 본 연구의 애플리케이션은 이러한 장점들을 적극적으로 활용한 것이며 교실밖에서, 또 정규수업 이후에도 활용할 수 있어서 지속적인 학습 자원의 관리와 자기 주도적 학습의 가능성을 열어두고 있기에 더욱 효과적이라고 할 수 있다.

A community can have a physical presence or can be formed from a group of people who communicate remotely via a conference call, a fixed Internet chatroom or instant message solution and most recently, a mobile handset. The mobile handset gives community members the advantage over fixed line or physical communities that they are not constricted by time or place as to when they can communicate with any members of their community. Operators, riding on the back of the SMS boom, are deploying community applications to increase both average revenue per user and customer loyalty. The purpose of this study is to find the effects of the characteristics of mobile community on the consumers'satisfaction and loyalty so that operators'participation in mobile community could be enhanced. A general model for the study was proposed with three independent variables. The variables are community usability(dialog and social support, information design, navigation, access), community sociability (purpose, people, policies), and mobile community content(location, personalization, immediacy, availability).

The current study was conducted to examine the temporal and spatial activation sequences related to morphosyntactic, semantic and orthographic-lexical sentences, focusing on the morphological-orthographic and lexical-semantic deviation processes in Korean language processing. The Event-related Potentials (ERPs) of 15 healthy students were adopted to explore the processing of head-final critical words in a sentential plausibility task. Specifically, it was examined whether the ERP-pattern to orthographic-lexical violation might show linear precedence over other processes, or the presence of additivity across combined processing components. For the morphosyntactic violation, fronto-central LAN followed by P600 was found, while semantic violation elicited N400, as expected. Activation of P600 was distributed in the left frontal and central sites, while N400 appeared even in frontal sites other than the centro-parietal areas. Most importantly, the orthographic-lexical violation process revealed by earlier N2 with fronto-central activity was shown to be complexes of morphological and semantic functions from the same critical word. The present study suggests that there is a linear precedence over the morphological deviation and its lexical semantic processing based on the immediate possibility of lexical information, followed by sentential semantics. Finally, late syntactic integration processes were completed, showing different topographic activation in order of importance of ongoing sentential information.
