In this study, the smart docent interface provided at 25 exhibition halls at domestic and foreign were compared and analyzed based on affordance. Heuristic evaluation techniques were adopted, centered on a small number of experienced people, and six research participants were selected based on Jacob Nielsen's guidelines that five to eight people per set of research can achieve sufficient results. As a result of comparative analysis of affordance, smart docent used in the Oriental showed a higher average value than smart docent used in the Western, but a lower value for sensory affordance alone. In addition, the categories were subdivided to derive the affordance values for each country, and a singularity was found that the sensory affordance of smart docents used in the United States represents the highest value compared to other countries. In conclusion, this study was able to compare the four affordances of smart docents used in domestic and foreign exhibition halls while presenting directions for future behavioral improvement, which could provide practical implication for smart docent interface design and exhibition hall service strategies.

Objective : This study aims to assess the potential of utilizing large language models in pattern identification education by developing a simulated patient with fatigue and dual deficiency of the heart-spleen pattern. Methods : A simulated patient dataset was constructed using the clinical practice examination module provided by the National Institute for Korean Medicine Development. The dataset was divided into patient characteristics, sample questions, and responses, and utilized to design the system, assistant, and user prompts, respectively. A web-based interface was developed using the Django framework and WebSocket. Results : We developed a simulated fatigue patient representing dual deficiency of the heart-spleen pattern through prompt engineering. To make practical tools, we further implemented web-based interfaces for the examinee's and evaluator's roles. The interface for examinees allows one to examine the simulated patient and provides access to a personalized number for future access. In addition, the interface for evaluators included a page that provided an overview of each examinees' chat history and evaluation criteria in real-time. Conclusion : This study is the first development of an educational tool integrated with a large language model for pattern identification education, which is expected to be widely applied to Korean medicine education.

Accurate and efficient monitoring of dynamically changing environments is one of the most important requirements for ubiquitous network environments. Ubiquitous computing provides intelligent environments which are aware of spatial conditions and can provide timely and useful information to users or devices. Also, the growth of embedded systems and wireless communication technology has made it possible for sensor network environments to develop on a large scale and at low-cost. In this paper, we present the design and implementation of a monitoring system that collects, analyzes, and controls the status information of each sensor, following sensor data extracted from each sensor node. The monitoring system adopts Web technology for the implementation of a simple but efficient user interface that allows an operator to visualize any of the processes, elements, or related information in a convenient graphic form.

The subdivision surface is the limit of recursively refined polyhedral mesh. It is quite intuitive that the multi-resolution feature can be utilized to simplify generation of NC (Numerical Control) tool paths for rough machining. In this paper, a new method of parallel NC tool path generation for subdivision surfaces is presented. The basic idea of the method includes two steps: first, extending G-Buffer to a strip buffer (called S-Buffer) by dividing the working area into strips to generate NC tool paths for objects of large size; second, generating NC tool paths by parallel implementation of S-Buffer based on MPI (Message Passing Interface). Moreover, the recursion depth of the surface can be estimated for a user-specified error tolerance, so we substitute the polyhedral mesh for the limit surface during rough machining. Furthermore, we exploit the locality of S-Buffer and develop a dynamic division and load-balanced strategy to effectively parallelize S-Buffer.

This paper is a research on an evaluating method for the dynamic signature verification system. It is described about various factors such as error rate, the size of signature verification engine, the size of the characteristic vectors of a signature, the ability to distinguish similar signatures, the processing speed of signature verification and so on. This study identifies factors to consider in evaluating signature verification systems comprehensively and objectively without an officially approved signature database, examines the meaning of each of the factors, and proposes criteria for evaluating and analyzing the factors.

발전계통 시뮬레이션은 CFO(전산유체역학)을 이용한 시뮬레이션으로서 다차원 미시적인 현상에 대한 시뮬레이션을 뜻한다. 주요 특징으로써 다수의 컴포넌트로 구성된 계통의 다양성으로 보일러, 급수계통, 증기계통, 복수계통 등 다양한 계통들이 존재하고 있다. 따라서 다양한 컴포넌트 모듈을 저장할 수 있는 GUI(Graphic User Interface) 기반의 시뮬레이션 툴이 필요하게 되었다. 현재 발전계통 시뮬레이션 툴의 문제점은 외국의 상용화 툴에 전적으로 의존하고 있으며 이는 곧 시뮬레이터 유지 보수의 어려움을 초래하게 되었다. 본 논문에서는 발전계통 시뮬레이션을 위한 컴포넌트 모듈의 생성, 모듈과 그래픽 라이브러리간의 연결, 유량-압력 알고리즘을 이용한 계통 Solver를 설계하고 멀티스레드를 이용한 복수개의 계통 시뮬레이터 구현 방법을 소개한다.

A software platform which is able to evaluate the performances of a GPS/INS integrated system has been developed in this paper. And it consists of four parts including GUI(Graphic User Interface) part, GPS part, INS part and integrated filter part. It basically offers the loosely, tightly and deeply coupled GPS/INS algorithms, and many design parameters can be changed by users via GUI. Each functions of the platform has been confirmed with GPS signals and IMU data from commercial simulators.

The Mission Analysis and Planning System (MAPS) has been developed for a low earth orbiting remote sensing satellite, Korea Multipurpose Satellite-I (KOMPSAT-I), to monitor and control the orbit and the attitude as well as to generate mission timelines and command plans. The MAPS has been designed using a top-down approach and modular programming method to ensure flexibility in modification and expansion of the system. Furthermore, a graphical user interface has been adopted to ensure friendliness. Design, Implementation, and testing of the KOMPSAT is discussed in this paper.

The coke oven plant on a steel works has not, in the past, been regarded as a prime user of modern instrument technology. The reason for this perception may be due to the fact that the basic design of the coke battery has been changed little over the years. The recording and analysis of oven pushing force on a routine basis is seen as a means of monitoring plant operation. A torque sensor is set up at the shaft of the rotor for measuring pushing force. Pushing force data which is communicated form torque sensor to staor by telemetry method are shown on MMI(Man-Machine Interface) screen and stored in the database automatically. Perhaps the most important feature is that is allows a problem oven to be identified at an early stage and for corrective action to be taken before it develops into a refusal to push. In this way the mechanical loads imposed on the battery structlure can be held to a necessary minimum, so helping to prolong its service life.

기업내부의 최적화를 위하여 도입 된 ERP 는 급변하는 경영환경을 반영하여 전략적 수단으로 기능하는데 까지 발전하여 왔으며, 현재에는 다른 시스템이나 경영 도구들과의 연계성이 더욱 강조되고 있다. 특히 확장된 ERP 의한 영역인 SEM(Strategic Enterprise Management)은 각 기업들이 성과평가와 시나리오 경영 등 최신 경영도구들의 본격적인 도입으로 각광받고 있으며, 경영계획 및 시뮬레이션(BPS : Business Planning & simulation), 경영 통합 및 소싱(BCS : Business Consolidation & Sourcing), 기업실적 모니터(CPM : Corporate Performance Monitor), 이해당사자 관계관리(SRM : Stakeholder Relationship Management) 등의 세부 시스템으로 구성된다. 특히 경영계획 시스템은 개선된 경영계획 프로세스 모델과 시뮬레이션을 바탕으로 구현될 수 있으며, 본 논문에서는 경영계획 프로세스 모델을 바탕으로 이를 시스템화 하기 위한 경영계획 시뮬레이션 시스템 아키텍처와 User Interface를 제안하였다.
