Extended reality-assisted training offers repeatable learning opportunities at a low cost. This paper proposes a smart glass application for training core nursing skills to nursing students, who often need to memorize and practice training sequences. The proposed smart glass application interactively presents a series of instructions to help students remember and perform two core nursing skills in the correct order. We conducted a usability test on 30 undergraduate nursing students in their third year using the smart glass application. Our initial findings show that many students have positively evaluated the possibility of using smart glasses for training, but have also encountered several challenges with the smart glass application's user interface, which takes time to adapt.

The microprogram is the key technology of the implementation of the processor's control unit. But the coding and testing it is the most tedious process in the developing a new computer system. We developed the conversational micro architecture simulator(C-MAS) in order to use it as a microprogram development tool and a run time analyzer of the microprogram. We discuss the hardware description language(HDL) for a smulation, the design constraints of the C-MAS, and the user interface of it in this paper. We used the C language as the description language, and developed it on the berkeley UNIX4.2.

본 논문에서는 사용자에게 편의성을 제공하며 기존 물물거래 시스템의 단점을 보완한 웹기반의 물물교환 시스템을 제안한다. 대부분 사람들이 중고거래나 필요 없는 물품에 대해 판매를 하는 목적은 자신에게 필요 없는 물건을 처리하고 필요한 물건을 구매하기 위해서이다. 이러한 사용자들의 관점에서 보았을 때, 필요한 물건을 얻기까지의 과정이 장시간 걸린다는 단점이 있으며, 사람들이 필요 없는 물건을 버려 낭비되고 과소비되는 경우도 있다. 이러한 문제를 해결해서 필요 없는 물건을 필요로 하는 사람과 물물교환을 하여 불필요한 소비를 줄이고 필요한 제품을 서로 쉽게 찾고 교환할 수 있도록 사용자에게 편의성을 제공하는 물물교환 시스템을 제안한다.

E-Learning 환경에서 학습자에게 보다 정확한 맞춤형 교육 시스템을 제공하기 위하여 평가 문항 및 학습 문항의 난이도, 변별도 등과 같은 문항 정보 활용이 필요하다. 본 논문에서는 문항 난이도, 변별도의 수치를 메타데이터에 저장하고, 평가 문항 및 학습 문항을 저작할 수 있는 템플릿(Templates) 및 GUI(Graphical User Interface) 기반의 SMIL(Synchronized Multimedia Integration Language) 저작도구를 설계 구현 하였다. 구현한 시스템은 SMIL 문법을 모르는 교수자가 문항 난이도, 변별도를 메타데이터에 저장하고, 학습 문항을 쉽게 저작하는데 효율적이다. 또한 저작된 문항은 XML(Extensible Markup Language) 기반 메타데이터를 활용함으로서 다른 플랫폼과의 통합 관리 및 재사용에 용이하다.

그리드 컴퓨팅은 가상조직(VO, Virtual Organization)이란 개념을 사용하여 분산된 컴퓨팅 환경을 구축한다. 이러한 가상조직에 존재하는 그리드 서비스 및 그리드 리소스를 활용하기 위해서는 사용자가 직접 서비스 및 자원에 대한 모니터링 작업을 수행해야 한다. 따라서 본 논문에서는 가상조직을 관리하고 가상조직에 존재하는 자원 및 서비스의 모니터링 작업과 그리드 서비스의 배치 및 해지 작업을 수행할 수 있는 웹 기반의 사용자 인터페이스를 제안한다. 웹 기반의 사용자 인터페이스는 사용자에게 편리한 작업 환경을 제공하기 때문에 서비스 및 자원의 활용 측면에서 편리성 및 사용의 용이성을 제공할 수 있다.

A new research of geographic information system has been focused on an open architecture, interoperability and extensibility in their design. In order to process huge data, multidimensional data and heterogeneous geographic format data, these research move away from monolithic system to open structure system managing application layer and user interface layer. Nowadays, many developers have used CORBA middleware for the OGIS systems. However, CORBA middleware has some problems that support only a point-to-point communication and takes a long time to transfer sever data to client. Thus, in this paper, we propose a method on modifying a point-to-point communication and implement the efficient communication method. The proposed method that transfer data from sever to client in one connection support a group communication and reduce a transfer time delay.

The paper is a design and implementation of the Hybrid Messaging System as integrating electronic mail system and common mail system based on PKI(Public Key Infrastructure), A user writes mail through Web Browser and sends the mail to Web Server. CGHCommon Gateway Interface) program sends the mail that was received through the Web Sever to Post Office Electronic Mail Server using SMTP(SimpleMail Transfer Protocol), The End Process program of the Hybrid Messaging System in a Post Office fetches the mail from the Post Office Electronic Mail Server using POP3 (Post Office Protocol 3), prints it and deliver it to recipients, Also, the Hybrid Messaging System is able to sign the mail with a sign private key that the Certificate Authority publics for users and encrypts the mail with a public key of the Post Office Web Server.

Indoor air-conditioning system(IAS) using wireless sensor network serves to reduce the amount of pollution entering the room from outside and also the pollution that is generated indoor. Small-size and lower power wireless sensor node and sensor interface board was designed for indoor air-conditioning system in buildings of offices and industrial establishments. Many sensor nodes forms Ad-hoc network topology using simple forwarding routing to transmit polluting gas concentration data from different rooms to the indoor air-conditioning system. Sensor node analyzes pollution concentration in the each room and air-conditioning system performs to air-distribution and air-inhalation according to room's pollution by regulating the fan of indoor air-conditioning system. To reduce power consumption electrochemical gas sensor was used in the design. Thus the designed system can optimize state of indoor environment. Graphic user interface displays node sate, gas concentration and temperature of each room.

The need to support the ICT-using teaching and learning at elementary and secondary schools has led to various digital content service systems. The systems are designed to target the teachers and the students as the major users. The problems involved in them is that they do not provide such services as the integrated search and the systematic use of interface in terms of actual users' use of teaching and learning digital content. It's because they have been created at demands at each time. In an attempt to solve this problem, this study set out to suggest the integrated meta-data items of a teaching and learning digital content, which reflects the Dublin Core Education, the international meta-data standard. It also aimed to design an entity-relationship model to realize the digital content. The results of the integrated meta-data and the entity-relationship model will be utilized as a basic research to help the users to search for various teaching and learning digital contents on an integrated basis and to realize a consistent user interface. Furthermore, they are expected to contribute to the development a service system the teachers and the students can make better use of.
