KT starts MMS(Multimedia Messaging System) service based on wired BcN(Broadband Convergence Network) telephone on August, 2008. BcN telephones have various service functions, and MMS service has been serviced for years. However, we should check KT MMS service system. KT MMS service is based on a PS(presence server), so KT MMS system sends a MMS message to the most convenience terminal for each receiver. Most other current MMS system send MMS message to a terminal which the sender set directly. However KT MMS system decides called party terminal based on the receiver's situation.

최근 UPnP(Universal Plug and Play) 포럼은 인터넷을 통해 기기 간 연결을 가능하게 하는 UPnP 클라우드(Cloud) 규격을 제정하여 기존 UPnP 규격의 기능과 범위를 확장시켰다. UPnP 클라우드는 XMPP(Extensible Messaging and Presence Protocol)를 이용하여 서로 다른 도메인에 위치하는 UPnP 기기들을 연결시켜준다. 본 논문에서는 UPnP 클라우드 규격의 세부내용을 소개하고 UPnP 클라우드가 어떻게 원격으로 콘텐츠를 공유할 수 있는지 그리고 DLNA(Digital Living Network Alliance)와 연계될 수 있는지 알아본다.

세계적으로 공유 전동킥보드의 이용이 급증하면서 해당 수단과 관련된 다양한 연구들이 진행되고 있다. 아직은 초기 단계의 연구 결과가 나타나고 있으며, 그 중 통행에 영향을 미치는 주요 요인을 파악하는 연구들이 결과로 나타나고 있다. 특히 통행발생 모형 개발은 교통계획 측면의 활용에서 아주 중요하며 신교통수단인 공유 전동킥보드는 국내외적으로 통행발생모형 개발이 부재한 실정이다. 본 연구는 선행연구를 면밀히 검토하여 유의미한 변수들을 활용한 공유 전동킥보드 통행발생 모형을 개발하고자 한다. 공유 전동킥보드 특성 상 주요 서비스 지역과 그 외 지역의 통행 특성이 상이하다. 서비스 통행량에 근거하여 서비스 수준별 지역을 구분하여 지역별 통행발생모형을 구축했다. 분석 결과, 주요 서비스 지역 내 공유 전동킥보드 통행에 영향을 미치는 요인은 대학 유무, 근접중심성, 문화지역 면적 등으로 나타난 반면, 그 외 지역 내 공유 전동킥보드 통행에 영향을 미치는 요인은 대학 유무, 매개중심성, 통행거리 등으로 나타났다.

This study analyzes consumers' responses toward chatbot services in a fashion retail context. Anthropomorphism and personalization of chatbots are proposed as critical features of a chatbot service that attract positive behavioral intentions from consumers. Social presence, trust, and enjoyment are expected to mediate associations among chatbot characteristics and consumers' acceptance of the service. The experiment was conducted in a controlled laboratory; participants were instructed to engage with a virtual shopping chatbot service via their cell phone and complete a questionnaire online. A total of 189 participants participated in this study along with and four experimental groups of 2 (anthropomorphism: high / low) × 2 (personalization: high / low) were formed with between-subject design. The collected data were analyzed using SPSS 25.0 and SPSS PROCESS Macro programs. The results show that the effect of anthropomorphism and personalization of chatbots on consumers' service acceptance intention when using fashion shopping chatbot service were mediated sequentially by social presence, trust, social presence and enjoyment. This study provides meaningful evidence on the effects of chatbots characterized by anthropomorphism and personalization on consumer responses, acceptance intention and associated psychological mechanisms by expanding the field of consumer behavior into chatbot services.

본 연구는 사용자 경험을 중심으로 하여 증강현실 패션 어플리케이션에 대한 소비자 만족도에 영향을 미치는 요인들을 살펴보고자 하였다. 증강현실 패션 어플리케이션을 이용해본 중국 사용자 280명을 대상으로 설문조사를 실시하고 구조방정식 모형을 사용하여 분석하였다. 결과에 따르면 사용자 경험이 현존감, 몰입, 만족도에 각각 영향을 미치고 개인화 수준도 만족도를 증가시키는 것으로 나타났다. 현존감의 경우 몰입을 높이고 몰입이 만족도를 제고하는 것으로 나타나 현존감이 몰입을 경유하여 만족에 간접적인 영향을 미치는 것을 확인하였다. 본 연구의 결과는 향후 증강현실 기술에 주목하고 있는 다양한 산업에서 소비자들의 제품을 체험을 돕고 어플리케이션에 대한 만족도 향상을 위하여 고려해야 하는 요소들을 파악하여 전략적인 시사점을 제공할 수 있을 것으로 기대한다.

With the steady development of Artificial Intelligence (AI), online stores are adopting chatbot services as virtual shopping assistants. This study proposes the concept of para-social presence to explore the undiscovered role of fashion chatbots' emotional and relational characteristics on service acceptance. Based on the Technology Acceptance Model (TAM), this study investigates the effect of a chatbot's para-social presence on service acceptance intention through consumers' beliefs. The web-based experiment was conducted on adult consumers who experienced chatbot services in an online shopping situation. A total of 247 responses were analyzed using confirmatory factor analysis, structural equation modeling, and multi-group SEM by AMOS 21.0 and SPSS 23.0. The findings illustrate that the chatbot's intimacy positively influenced consumers' perceived enjoyment, while the chatbot's understanding had a significant effect on perceived usefulness and ease of use. The chatbot's involvement had a positive effect on all consumer beliefs. Moreover, perceived ease of use had a positive influence on usefulness. A greater level of perceived usefulness and enjoyment positively heightened consumers' service acceptance intention. This study also verifies the moderating role of a need for human interaction. Consumers with a high need for human interaction have a relatively low tendency to perceive chatbot services as useful.

Purpose: The purpose of this study is to examine the factors affecting the intention to continue using the metaverse platform service from the user's point of view. Methods: The study conducted a survey of experienced people using Zepeto, Ifland, Gather Town, Zep, Roblox, Fortnite, and Minecraft, which are virtual world types among metaverse types, and valid 415 data were analyzed by SPSS (ver 22.0) and R (ver 4.1.0) program packages. Results: As a result of empirical analysis, it was found that interactivity and social presence among the characteristics of metaverse affected expectation confirmation, and sensory affordance and functional affordance affected expectation confirmation as affordance factors. In addition, all four characteristics of metaverse, reliability, playfulness, interactivity, and social presence, were found to have the greatest affect on perceived usefulness, and it was analyzed that playfulness, social presence, and reliability were influenced in order. The affordance factor was also found to have a positive effect on physical affordance, sensory affordance, and functional affordance. This study was found that it had a positive effect on the relationship between expectation confirmation and satisfaction and the relationship between perceived usefulness and satisfaction. satisfaction was analyzed to lead to continuance intention. Conclusion: This study is meaningful in that it examines the perspective of users who can be called customers of metaverse platform services. Based on the results of this study, it is expected to have a significant effect on the development of metaverse platform services not only on platform operators that provide metaverse platform services but also on providers who plan events and education using metaverse platform services.

Nowadays, encryption is core technology widely used in IT industry to protect private information of individuals and important intellectual assets of companies. However, when criminals and terror suspects abuse such technology, national security can be threatened and law enforcement can be disturbed. To prevent such adverse effects of cryptography, some nations have enacted legislations that allow legally obtained encrypted data to be decrypted by certain law enforcement agencies. Hence it is imperative that firms having international presence understand and comply by each nation's regulations on decryption order. This paper explains circumstances under which legislations on decryption order were established, organizes countries with regulations and punishment, explores what global enterprises need to consider in making policies to effectively respond to decryption orders, and suggests that technological methods and managerial guidelines for control of encryption be established.

The purpose of this study is to examine negative IT performances produced by irrational fashion-mimic IT investments in firms. Since most studies have been carried out on the assumption of rational investment decisions, many of them have revealed positive investment process and performances in firms. However, fashion-mimic investments to follow the paths of market leaders rather than rational investment decisions have been of frequent occurrence in many firms. This study divided types of mimic investments into subgroups where one subgroup has fashion-mimic properties and the other subgroup retains rational-mimic properties. We compared differences in performance of these subgroups to investigate effects of irrational investments in IT projects. The results indicated that there are differences in performance between fashion-mimic and rational-mimic investments. Additional analysis also revealed differences in performance at the presence of CEO control in the case of fashion-mimic investment subgroup.
