This paper is a study on modeling of an NFC antenna to be inserted into a steel pallet for conveying selected good products through a vision system to a threaded screw from CNC equipment. The CNC equipment used here incorporates the information communication technology (ICT) corresponding to the Internet of Things (IoT), and the smart factory system technology that produces information by exchanging information freely in two directions by connecting the POP corresponding to the service Internet is evolved Equipment. Therefore, it is possible to collect position information on the threaded workpiece by applying NFC antenna designed considering iron pallet used for material management so as to grasp estimated completion time and actual production amount according to production instruction from existing analog type equipment to POP monitoring system And investigated its characteristics.

Interim immediate denture is fabricated to minimize the period of edentulousness after removal of the patient's remaining teeth and before delivery of final prosthesis. In the case of using the CAD/CAM system, there is an advantage in that the manufacturing process in the clinic and laboratory can be simplified by overcoming some of the limitations of manufacturing interim immediate dentures in the traditional way. However, there are also disadvantages in that errors occur in the process of transmitting information about the patient's intermaxillary relationship to the digital network of the laboratory, resulting in unstable occlusal relationships or non-esthetic prostheses. To overcome this problem, using the simple and accurate POP BOW system's occlusal plane digital transfer method, it was possible to fabricate an esthetic and functional 3D printed interim immediate denture after removal of the remaining upper and lower anterior teeth.

The beauty industry of China POP-UP store service, has entered the peak development period. This paper takes China Estee Lauder POP-UP store as an example, based on the user experience of interactive marketing mode in Beauty POP-UP store under the new retailing model. The paper aims to establish a system interaction design process integrating online and offline to help enterprises complete the sustainable development of marketing services. To achieve this goal, this study uses questionnaires to investigate the key elements of user experience, customer journey map to determine the user pain points, and completes the design of the new system process. This process can provide designers with a new perspective through experimental verification, with high timeliness and practicability. It also promotes the collaborative optimisation and upgrading of physical retail and online retail and provides theoretical support and practical basis for other enterprises.

과학기술의 발전에도 불구하고, 장애인들이 정보통신 서비스를 이용하기는 힘들다. 특히 이러한 장애인을 대상으로 구현된 시스템은 미미한 실정하며, 그 혜택을 누리기 힘든 실정으로 이러한 문제들이 사회적인 문제로 대두되고 있다. 본 연구에서는 시각장애인을 대상으로 한 전자메일 음성 서비스와 설계 및 구현하여 보았다. 구현된 이 시스템은 안내음성에 다라 사용자의 선택에 의하여 수신된 메일정보를 들을수 있고 POP3를 사용하여 특정서버에 관계없이 메일을 확인할 수 있으며, 대중화 통신매체인 전화를 사용하여 외부에서도 그 내용을 확인할 수 있다. 이러한 시스템은, 사용자가 특별한 소프트웨어의 구입이나 설치가 필요 없는 장점이 있다. 이 시스템은 7bit, 8bit, base64, QP 등의 MIME 디코딩 방법을 지원하며, 구현된 시스템은 청주대학교 POP3 메일서버를 사용하여 성공적으로 테스트가 되었다. 이러한 시스템 개발은 복지시설 차원이나 시각장애인들의 정보통신 서비스를 사용한다는 측면에서도 중요한 의의를 갖는다고 본다.

1994년 국내에 인터넷 붐이 일어나고 사용이 보편화되면서 전자메일은 개인간의 메세징을 가능하게 해주는 기반기술 중 하나로 자리잡고 있다. 기존의 POP(Post Office Protocol) 프로토콜을 이용하던 전자메일 시스템은 POP 프로토콜의 불편함을 제거한 별도의 세팅없이 지역, 언어, 시간에 제약이 없는 웹기반의 메세징 시스템이 등장하게 되었다. 현재 이러한 메세징 시스템에 사용되어지는 MTA(Mail Transper Agent)로는 sendmail을 거의 표준으로 받아 들여지고 있다. 그러나 sendmail은 단일 모듈로 작성되었으며 덩치가 매우 크고 보안상 문제점도 지적되고 있다. 이에 본 논문에서는 sendmail의 문제점을 효율적으로 해결할 수 있는 qmail의 활용방법을 제시하고 웹과 qmail을 연계할 수 있도록 자바를 통한 보안성, 안전성, 효율성이 강화된 인터넷 메세징 시스템을 설계 및 구현한다.

In order to manufacture functional and esthetic prostheses, it is essential to accurately transmit information about the patient's occlusal plane. In particular, in the case of a completely edentulous patient, the occlusal plane is very important to correctly support the soft tissue, to achieve aesthetic harmony with the facial appearance, and to properly pronounce it, and to form a balanced occlusal relationship for stable mastication. In the conventional method, various facebow systems were used to transmit patient's information from the clinic to the laboratory, but there were several limitations in the process of transferring them to CAD. To simplify this process, a prefabricated POP (PNUD Occlusal Plane) Bow system was recently developed. In this case, a CAD-CAM (Computer-aided design-computer-aided manufacturing) treatment dentures reflecting the patient's occlusal plane information was manufactured using the POP Bow system during the treatment of a completely edentulous patient, and aesthetic and functional satisfaction was obtained.

DNC(Distributed Numerical controller)는 제품을 생산하기 위해 현장용 컴퓨터를 이용하여 공작기계 및 주변장치를 제어하고 감시한다. 본 논문에서는 SFC/OP(Shop Floor Control/point of Production) 시스템과 연계시키기 위한 DNC 시스템의 구조를 제시한다. 본 시스템은 도면 정보를 유기적으로 연결하여 작업절차서를 조회하고, 작업절차서 및 NC 프로그램/공구 보정 데이타를 인덱스 데이터베이스화하고, 소재·지그·공구를 연계한다. 또한 생산정보를 빠르고 능동적으로 현장 작업자에게 전달하고, 기계의 상태정보를 기계로부터 직접 수집함으로써 실시간 모니터링이 가능하다. 분석 및 설계단계에서는 실시간으로 발생하는 이벤트를 처리하기 위해 상태전이도(State Transition Diagram)를 사용한다. 서버 DBMS(Database Management System)로 관계형 데이터베이스를 채택한 Oracle을 사용하였고, 프로그램 개발도구로는 Developer 2000, Microsoft Visual C++ 5.0을 사용하여 구현한다.

In this paper, we propose an architecture of the DNC system for Shop Floor Control/Point of Production(SFC/POP). The DNC system to be presented this paper retrieves line-up sheets which include the drawing information, making a index database for line-up sheets, NC programs and tool adjustment data. And it is interface with a raw material, jig and tool information. Also, the DNC system transmits operation information to real workers rapidly, and supports realtime monitoring by collecting the state information of machines directly. In the analysis and design phases, this paper models realtime events using the state transition diagrams. In the implementation phase, we use the ORACLE DBMS(Database Management System) as the DBMS and Developer 2000 and Microsoft Visual C++ 5.0 as the programming tools.

This study intend to make easy modification, even if there is a new job or structure change, by modularizing program and computerize and automation of production control management used in CIM. Under the condition where manager control production on the job-site, for increasing connection with other operation and management on the computer by monitoring center computer, Recognizing information by computer is needed, it is possible by converting transaction. So production increase and quality improvement are possible by diminishing manager's and producer's work with the result of the study combining POP and CIM, after that, in e-business and m-business period that every enterprise must pass, customer satisfaction and sales promotion are possible with employee's computerizing minds. These study result also can knowledge process condition with theoretical class and have a power in finding a solution with foundation of theoretical knowledge.
