The growth of the propagated NFC provides the various services with respect to internet applications, which it can be predicted from the simple internet services to the privated services. This paper proposes the clustering of information retrieval system model using NFC tag of access information for utilizing the similar information of the tag. The proposed model can search the similar information of the tag using the access information of NFC tag. In addition, it can cluster the similar retrieval information into topic cluster for utilizaing users.

NFC(Near Field Communication)는 13.56Mhz를 사용하는 근거리 무선통신으로 PC, 휴대폰 등의 전자 기기간 양방향 데이터를 송수신할 수 있는 기술이다 [1]. 안드로이드를 중심으로 채택되기 시작한 NFC 기술은 스마트폰과의 연결을 통하여 새로운 다양한 비즈니스 모델을 만들어 내고 있다. 본 논문에서는 이러한 NFC기술을 대형 마트 도메인에 적용하여 마트를 방문하는 고객이 편리하고 빠르게 장을 볼 수 있도록 도와주는 애플리케이션 개발내용에 대해 기술한다. 본 애플리케이션을 이용하여 고객은 장보기 전에 구입할 상품을 장바구니에 미리 등록할 수 있으며 예산금액을 설정할 수 있다. 고객이 마트를 방문 시 출입구에 부착되어있는 NFC 태그를 인식하여 장바구니에 등록한 상품에 관한 맞춤형 정보를 얻을 수 있고 마트 진열대의 상품에 장착된 NFC 태그를 스마트 폰으로 인식하여 장바구니에 등록된 상품과 체크하며 장보기를 실시한다. 장보기 완료 후에는 포스기에서 NFC 태그를 인식하고 결제방법을 선택하고 결제를 한다. 결제 후 상품은 포장단계에 적용되고 포장이 완료된 후 배송하게 된다. 대형마트에서는 본 시스템을 갖춤으로써 고객들이 좀 더 편리하게 쇼핑할 수 있도록 도와줄 수 있다.

In this study, we investigated the effect of the number of passes through agrinder on the pore characteristics of nanofibrillated cellulose (NFC) mat. The beaten pulp suspension was used to make NFC suspension using a grinder. To evaluate the pore characteristics of a NFC mat, the surface morphology of the dried NFC mat was observed with FE-SEM and the specific surface area was analyzed with BET nitrogen gas adsorption. The structure of NFC mat was changed with the different number of passes and drying methods. The specific surface area of NFC mat increased with the increase in the number of passes. The 20-passed NFC mat had 20 times larger specific surface area ($141m^2/g$) compared to the 0-passed NFC mat. The specific surface area was strongly correlated with the average pore size in NFC mat. The average pore diameter in NFC mat was calculated from the gas sorption isotherms using BJH model. The value was 13 - 15 nm, indicating that the NFC mat had mesoporous structure.

To invigorate and develop marketing strategies in public performance, this thesis reviewed the literatures such as papers, academic materials and internet information on marketing in public performance. We performed surveys for specialists and non-specialists of public performance from on-line or off-line for questionnaire which is classified as demographic characteristics, tendency for seeing public performance and for knowledge of NFC and LBS, and analyzed the questionnaires for knowing the effects of NFC and LBS marketing in public performance. This thesis revealed generally a higher level of satisfaction with NFC than LBS, especially for specialists as compared with non-specilists. The reason of a lower level of satisfaction with LBS than NFC is that LBS technique has privacy problem about personal information by exposing the user location information. The reason of a lower level of satisfaction with NFC to non-specialists is that there are insufficiency of promotion for NFC technique and contents utilizing NFC. A total average score for a level of satisfaction of NFC and LBS service was revealed high as more than 3.50 out of 5.00. Through this thesis we suggest the public performance marketing strategies.

NFC represents the 2nd generation of the proximity contact-less technology, which beyond the RFID, supports peer-to-peer communication, and enables consumer access to aggregated services, anytime, anywhere, with any type of consumer stationary and mobile devices. NFC is a short range device wireless technology designed to exchange data, initiate connections with other wireless networks and act as a secured smart key for access to services such as cashless payment, ticketing, on-line entertainment and access control. In this paper, the NFC services for social networking applications are studied, and the signal flow of SNS application based on NFC P2P for smart devices and server model is proposed.

NFC(Near Field Communication) is a wireless data exchange technology in 13.56MHz frequency band between devices. The NFC Forum defines the NDEF(NFC Data Exchange Format) exchanging data format between NFC devices and NFC Tags, the NFC RTD(Record Type Definition) defining the record types in the NDEF messages, the Smart Poster RTD in order to replace current paper posters and the Signature RTD to ensure the authenticity and integrity for NDEF records. But the previous smart poster authentication scheme have the weaknesses of using the PKI(Public Key Infrastructure) with certificates to verify the public key for the smart poster authentication and requiring the additional storage capacity of NFC tags for the authentication path. Therefore in this paper we propose a smart poster authentication scheme and implementation based on the authentication URL, a digital signature and a public key without the PKI and certificates for the smart poster authentication.
