Utilizing the tools such as CLIPS can reduce the time that it takes to develop expert systems. CLIPS is a development tool for expert system and has public inference engine and utilities. However, skilled programming is needed to run CLIPS on Windows 95, and proper interfaces for knowledge engineers or end-users who do not have good programming ability should be developed. Therefore, the user-friendly interfaces including htitle, hmenu, hyesno, htextdisplay, and hrun were developed and added to CLIPS. The intefaces were excuted in command-line mode of CLIPS on Windows 95. Also, htitle and hmenu can display graphic files for expert system users comprehension. An expert system was constructed using the interfaces and examples were displayed.

Currently, the VHE (suggested for global roaming user to provide personal service environment) implementation scenario is being proposed to realize 3G network requirements. However, developing VHE scenarios are focused on signal flow between node and network, and network and network. this case may result in weakness to protect subscriber's privacy in 3G network which commonly uses visited network. In this paper, we reanalyze a several VHE implementation scenarios for user profile protection, indicate a problem concerning user privacy, and finally, design a procedure to cope with vulnerability in VHE implementation scenario.

As computer performance and needs of user convenience increase, computer user interface are also changing. This changes had great effects on software development environment. In past, text editors like vi or emacs on UNIX OS were the main development environment. These editors are very strong to edit source code, but difficult and not intuitive compared to GUI(Graphical User Interface) based environment and were used by only some experts. Moreover, the trends of software development environment was changed from command line to GUI environment and GUI Editor provides usability and efficiency. As a result, the usage of text based editor had decreased. However, because GUI based editor use a lot of computer resources, computer performance and efficiency are decreasing. The more contents are, the more time to verify and display the contents it takes. In this paper, we provide a new parser that provide multi view editing, incremental parsing and multiple entry of abstract syntax tree.

과학기술이 발전함에 따라 미래의 전쟁에서는 보다 복잡한 전장 환경에서 지금보다 훨씬 정밀하고 다양한 무기체계들이 활용될 것으로 예상된다. 이때 복잡한 전장 환경과 다양한 무기체계들을 하나로 연결하여 전장상황을 인식하고 전장을 가시화 함으로써 지휘관 및 참모들에게 필요한 정보를 제공해 주는 시스템을 지휘통제체계(C4I)라고 한다. 지휘관 및 참모들은 지휘통제체계를 활용해 효율적인 전투지휘를 위해 컴퓨터나 종이지도 등을 활용해 미리 충분한 예행연습을 함으로써 지휘통제 및 의사결정 능력을 향상시키는데, 이를 전투지휘훈련이라 한다. 지휘통제훈련은 이러한 전투지휘훈련의 한 과정이다. 과거에는 지휘통제훈련을 위해 2차원(2D) 종이지도나 컴퓨터 스크린을 활용하였기 때문에 가시선 분석, 통신장비의 난청지역 분석, 병력의 진지 편성, 그리고 부대의 기동로 판단 등이 제한될 수밖에 없었다. 하지만 최근에는 이러한 단점을 극복하기 위해 3차원(3D) 기반의 지휘통제훈련 시뮬레이터들이 개발되고 있다. 이러한 추세에 발맞추어 본 논문에서는 증강현실(Augmented Reality, AR) 글래스를 활용한 다중 사용자 기반의 지휘통제훈련 시뮬레이터를 제안한다.

컴퓨터 그래픽스와 빠른 하드웨어의 발달에 힘입어, WYSIWYG(What You See Is What You Get)로 특징지워지는 GUI(Graphical User Interface)는 기존의 사용자 인터페이스 개념을 컴맨드를 이용한 언어모델에서 풀다운 메뉴, 스크롤바, 아이콘 등을 이용한 공간모델로 바꾸어 놓았다. 여기서 개발된 선박개념설계를 위한 그래픽 사용자 인터페이스 모델(MBASWIN)은 Event-driven 프로그래밍 기법과 객체지향 개념을 도입하였다. 또한 기존의 설계 프로그램이 인터페이스 부분을 포함하여 프로그램 전체를 제어했던 방식에서 벗어나, 설계 프로그램과 사용자 인터페이스 부분을 완전 분리하여, 사용자 인터페이스 루틴이 설계 루틴들을 제어하는 방식을 도입하였다. 이를 이용하여 설계자는 유연성있는 설계를 수행할 수 있게 된다.

The previous research has been mainly focused on individual technology of voice recognition, voice synthesis, translation, and bone transmission technical. Recently, commercial models have been produced using aforementioned technologies. In this research, a new automated translation support system concept has been proposed by combining established technology of bone transmission and wireless system. The proposed system has following three major components. First, the hybrid system consist of headset, bone transmission and other technologies will recognize user's voice. Second, computer recognized voice (using small server attached to the user) of the user will be converted into digital signal. Then it will be translated into other user's language by translation algorithm. Third, the translated language will be wirelessly transmitted to the other party. The transmitted signal will be converted into voice in the other party's computer using the hybrid system. This hybrid system will transmit the clear message regardless of the noise level in the environment or user's hearing ability. By using the network technology, communication between users can also be clearly transmitted despite the distance.

It was already realized at a current technological level of home network systems that the systems recognizes a user's simple order and carry out the order in the ubiquitous computing environment. However home is not a simple environment consisting into a large number of family members, so various order and situation would be needed accordingly. From now on we need to reach the technological level to infer that how is the user's behavior patterns and what kinds of service is the fittest to user who belong to the ubiquitous computing environment by using the result of the context interpreter. In this regards, active inferred-model needs to be suggested upgrading user's command into one step more higher level than the simple one adapting diversified feature. This study would like to suggest this active model recognizing context, which is user's environmental information applying basic network and inferring Context-based Service that user wants through the recognized result This study proposes a new method that can infer the user's desire in ubiquitous computing environment. First of all, we define a context as user's information of ubiquitous computing environment situation that user belongs to and we classify the context into 4W1H(Where, Who, When, What) formats. We construct Bayesian network and put the factor of context use as Bayesian network nodes. As a result, we can infer the user's behavior pattern and most proper service for user in the intelligent space from the probabilistic result of Bayesian network.

Objective: We introduce a hand gesture segmentation method using a wrist-worn wearable device which can recognize simple gestures of clenching and unclenching ones' fist. Background: There are many types of smart watches and fitness bands in the markets. And most of them already adopt a gesture interaction to provide ease of use. However, there are many cases in which the malfunction is difficult to distinguish between the user's gesture commands and user's daily life motion. It is needed to develop a simple and clear gesture segmentation method to improve the gesture interaction performance. Method: At first, we defined the gestures of making a fist (start of gesture command) and opening one's fist (end of gesture command) as segmentation gestures to distinguish a gesture. The gestures of clenching and unclenching one's fist are simple and intuitive. And we also designed a single gesture consisting of a set of making a fist, a command gesture, and opening one's fist in order. To detect segmentation gestures at the bottom of the wrist, we used a wrist strap on which an array of infrared sensors (emitters and receivers) were mounted. When a user takes gestures of making a fist and opening one's a fist, this changes the shape of the bottom of the wrist, and simultaneously changes the reflected amount of the infrared light detected by the receiver sensor. Results: An experiment was conducted in order to evaluate gesture segmentation performance. 12 participants took part in the experiment: 10 males, and 2 females with an average age of 38. The recognition rates of the segmentation gestures, clenching and unclenching one's fist, are 99.58% and 100%, respectively. Conclusion: Through the experiment, we have evaluated gesture segmentation performance and its usability. The experimental results show a potential for our suggested segmentation method in the future. Application: The results of this study can be used to develop guidelines to prevent injury in auto workers at mission assembly plants.
