Fear of contact exists due to the prevention of the spread of infectious diseases such as COVID-19. When using the common entrance door of an apartment, access is possible only if the resident enters a password or obtains the resident's permission. There is the inconvenience of having to manually enter the number and password for the common entrance door to enter. Also, contactless entry is required due to COVID-19. Due to the development of ICT, users can be easily identified through the development of face recognition and voice recognition technology. The proposed method detects a visitor's face through a CCTV or camera attached to the common entrance door, recognizes the face, and identifies it as a registered resident. Then, based on the registered information of the resident, it is possible to operate without contact by interworking with the elevator on the server. In particular, if face recognition fails with a hat or mask, the visitor is identified by voice or additional authentication of the visitor is performed based on the voice message. It is possible to block the spread of contagiousness without leaving any contactless function and fingerprint information when entering and exiting the front door of an apartment house, and without the inconvenience of access.

최근 스마트폰의 확산으로 다양한 어플리케이션 개발을 통한 새로운 서비스 시장이 창출되고 있으며, 그 중에서도 스마트폰만으로 가격을 지불할 수 있는 모바일 결제 서비스 시장은 사용자가 일일이 결제 수단을 가지고 다니는 불편함을 해소함으로써 큰 성장을 보이고 있다. 하지만, 대부분의 모바일 결제 서비스는 온라인에서만 사용할 수 있거나, 오프라인 매장에서 사용 시에도 사용자가 직접 계산대로 가야하는 등의 한계점들이 남아있다. 이러한 불편함을 해소하기 위해, 본 논문에서는 음식점에서 QR코드와 스마트폰을 활용해 고객이 앉은 테이블에서 메뉴 확인, 주문 및 결제가 가능한 서비스 플랫폼을 개발했다. 본 논문에서는 제안하는 서비스 플랫폼의 기능 검증을 위해 모바일 어플리케이션과 데이터 서버 플랫폼을 개발하고 메시지 교환을 수행함으로써, 효과적인 모바일 결제 서비스의 제공이 가능함을 확인하였다.

According to the cooperation between organizations increases, e-Commerce and virtual organizaions spread, because of IT development, the number of business processes increased from bounds of an organization to crossing organizational boundaries. In order to support dynamic setup of business processes among independent organizations, a formal standard schema of describing the business processes is basically required because of business process models over multiple organizations, which are defined in different fromat by business process modeling systems their own business process modeling systems. The vision of ebXML is to create a single global electronic marketplace where enterprises, without any concerns about size and geographical location, can meet and conduct their businesses with each other through the exchanges of XML-based messages. Therefore, this thesis also analyzes and implements an ebXML based choreography modeling system for supporting collaborations between organizations.

The role of influentials to maximize word-of-mouth effect can be seen to be very important. In this paper, we have the perspective of corporate marketing to understand Twitter influentials. We start from the point of view of who can induce eventually most exposure of tweets when he tweets the company's specific marketing messages. From this perspective, we observe both the follower influentials who have many followers and the retweet influentials who induce many retweets by visualizing graphs from network data collected via Twitter Search API. Although some users have small followers they may bring much more exposure than follower influentials if they can induce retweets by follower influentials. On the contrary, some retweet influentials who don't induce retweets by follower influentials may bring very little exposure. This suggests the fact that some small users who can induce retweets by influentials might have more important role than influentials themselves in order to increase the exposure of tweets. These users also are seen to have high centrality measures in the network structure.

This study aimed to interpreting the view of current media by artificial intelligence(AI) with the case of a TV show Person of Interest, which was broadcasted until 2016 in US. In this study, we first attempted to find how AI reflects the three laws of robotics, which often appear in Science Fictions. In addition, we paid attention to how the society looks according to the change of the manipulator of the AI, and as a result we derived the distinguishes of the show from other content dealing with robots or AI in terms of narrative. Through this study, we classified the messages in accordance of AI into three categories- importance of data sovereignty, potential of intelligence explosion, and blind faith in high technology. This study suggested that the show emphasizes the consciousness and attitude that should be possessed as a citizen who meets the era of AI prior to raising issue of 'what artificial intelligence is should be developed for our convenience?'

The current study examines the major variables -Facebook social connectedness and brand self-disclosure- that affect the relationship between users and brands. In this study, we assume that users communicate and build relationships with brands via Facebook brand fan pages, like they do with other users. Additionally, we test the effect of attitude toward Facebook fan page on intention to be a fan of the fan page. The results show that the brand's self-disclosure positively affects on attitude toward the fan page, but Facebook social connectedness has negative effects. Also, attitude toward the fan page has positive effects on the intention to be a fan. This study helps understand how brand messages are spreading across diverse Facebook users.

Nowadays, Internet is used worldwide and network traffic is increasing dramatically. Much of Internet traffic is due to the web applications. And I propose a new cooperative web caching scheme, called DCOORD which tries to minimize the overall cost of Web caching. DCOORD reduces the communication cost by coordinating the objects which are cached at each cache server. In this paper, I compare the Performance of DCOORD with two well-known cooperative Web caching schemes, ICP and CARP, using trace driven simulation. In order to reflect the cost factor in the network communication, I used the CSR(Cost-Saving Ratio) as our performance metric, instead of the traditional hit ratio. The performance evaluations show that DCOORD is more cost effective than ICP and CARP.

The development of various contents has been accelerated with the explosive increase of the number of internet users, the rapid expansion of wireless internet service and the pervasion of mobile terminal. Mobile service is able to offer the elastic service to anyone regardless of the place and the time. With this characteristics, this service could be extended even to the pace which the access was limited with the existing line service. The purpose of this study is to propose a system which is able to make a remote control of computer by means of mobile as an example of the production of contents for such mobile service. With this system it could be identified what kind of job a user of PC is making by mobile phone regardless of the time and place. The functions such as termination reboot, messenger, macro execution, and timer are included. The greatest advantage of the system proposed in this paper is to protect the youth, who are making an access recklessly to the harmful site, by use of mobile at my time and any place.

Typography is the field be needed the most emotional and potential originality in the visual designers works. The design process introduced by aesthetic results is depended on a designers sensibility and originality. Accordingly this study includes more detail suggestions for mental switchover and developing whole area of sense and its education which make more sincere and easy communication of sentences in typographic and messages, removing fixed ideas, that are, prejudice and preconception, is one of big problems in making originality through the educational programs for experimental typography approaching with a new vision. Today, the change of typographic environment carried the substance and effectiveness of traditional typography be suspected and new ways are growing fast to escape from these traditional value. This study introduces some education programs such as Typortrait, Typeface, Typographic Essay, Kinetic Typography to realize the experimental typography to meet a new stream and social needs under the situation of exoplosive change and harmony fairly with proposition of coexisting of inspiration and technology, and finally expected to develop and promote typography experiment newly and to make educational section understand and confirm them.
