This paper presents a newly proposed object-oriented finite element framework and its applications on dynamic analysis of plate girder bridge. The developed framework supports various types of finite elements, materials, constraints, loads, and solution methods. One major feature different from other object-oriented finite element programs is that static model and dynamic state can be easily read from or written to a file. In addition, the framework supports efficient DOF pattern handling for a node connecting elements with different DOF patterns, new multi-point constraint handling, and various scripting languages for easy use of the library. In order to show the applicability to dynamic analysis, dynamic moving load analysis on plate girder bridge is performed.

A GUI based pre/post processor program, which is based on the MFC and OpenGL library in the Windows O/S, hee been developed for NUFLEX Using this program, users are able to generate and modify structured or unstructured grid geometries, set all the parameters for the solver, and observe the results of the simulation in graphic view by vector or scalar plots. The mesh geometry data can be imported from or exported to other programs by supporting functions for reading from and writing to CGNS data format files.

본 논문에서는 최적의 성능을 갖는 병렬 프로그램을 개발하는데 필수 도구인 성능가시화기를 이식성, 확장성 그리고 효율성을 고려해 설계 및 구현한 PnP 스타일의 성능 가시화기에 대하여 기술한다. 본 가시화기는 기존 가시화기의 문제점인 수정 및 변용에의 어려움을 해결하기 위하여 독립된 계층구조인 인스트루멘테이션층, 인터페이스층, 가시화층으로 구성함으로써 확장성 및 이식성을 갖도록 하였다. 인스트루멘테이션층은 사건(event)을 포획하기 위해 개발된 라이브러리인 ECL(Event Capture Library)로 구성되며, 인터페이스층은 인스트루멘테이션층과 가시화층간에 확장성 있는 문제중심 인터페이스를 제공하기 위해 개발된 사건 기술 언어 및 Java 문제중심 엑세스 라이브러리로 구성되었다. 그리고 PnP 스타일의 성능 가시화기를 설계함으로써 뷰와 필터의 추가 및 수정이 용이하도록 가시화층을 구현하였다. 이렇게 구현된 성능가시화기는 독립된 도구로 사용될 수 있을 뿐 아니라 병렬 프로그래밍, 디버깅, 그리고 성능 분석이 통합된 프로그램 개발환경 구축의 핵심도구로서 활용될 수 있을 것이다.

A graphic vehicle modeling pre-processing program and a visualization post-processing program have been developed for AutoDyn7, which is a special program for vehicle dynamics. The Rapid-App for GUI(Graphic User Interface) builder and the Open Inventor for 3D graphic library have been employed to develop these programs in Silicon Graphics workstation. A Graphic User Interface program integrates vehicle modeling pre-processor, AutoDyn7 analysis processor, and visualization post-processor. In vehicle modeling pre-processor, vehicle hard point data for a suspension model are automatically converted into multibody vehicle system data. An interactive graphics capabilities provides suspension modeling aides to verify user input data interactively. In visualization post-processor, vehicle virtual test simulation results are animated with virtual testing environments.

This study was carried out to investigate the status and development direction of horse riding industry for rural development of Korea. Library research and field survey were conducted to collect relevant data such as number of horse and size of horse farms, facilities for horse riding and educational institutions for youths and farmers and the results obtained were as follows : Only a few institutions among high schools, colleges and universities were observed to deliver horse riding programs. For farmers, no equestrian specialist was available in agricultural extension offices. Horse meat is consumed mostly in Jeju Island in Korea. Relevant institutions should be also strengthened including formal and nonformal education for horse riding and much more schools and universities should adopt horse riding program for the training of youths and farmers. Considering the obesity problem, the nutritional composition of horse meat is better than those of pork or beef, so promotion of horse meat consumption also should be strengthened.

SNMP is a standard protocol for management of networking devices. Nowadays, most computer systems have capability to act as SNMP agents. In this paper, we describe our system monitoring software based on SNMP. It consists of a monitoring server, SNMP agents, and client programs. The monitoring server collects status information from the SNMP agents running on the monitoring target graphical display. We developed two version of clients, Java based standalone program and Web based program. Since most known SNMP packages are too big and heavy, we developed an efficient version of SNMP library for out system monitoring.

This paper presents a robot system that combines computer network and an autonomous mobile robot where RTOS is installed. We propose a wireless communication protocol, and also implement it on the RTOS of the robot system. Main controller of the robot processes the control program as a task type in the real-time operating system. Peripheral devices are driven by the device driver functions with the dependency of the hardware. Because the client and server program was implemented to support the multi-platforms by Java SDK and Java JMF, it is easy to analyze programs, maintain system, and correct the errors in the system. End-user can control a robot with a vision showing remote sight over the Internet in real time, and the robot is moved keeping away from the obstacles by itself and command of the server received from end-user at the local client.

This paper presents the evaluaton procedures and the estimation model for DSM potential on commercial sector in Korea. In general, the evaluation process of the potential savings for DSM measures or programs consists of baseline electricity consumption forecast and potential evaluation such as technical potential(TP), economic potnetial(EP), and achievable potential(AP). A library of energy conservation measures applicable to each end-use or apparatus is developed, and energy savings and other factors are applied to the baseline demand estimates of consumption to produce potential savings estimates. The purpose of this paper is to establish the evaluation process of those DSM potential for commercial sector. In case study, we applied it to commercial sector for horizon years by end-use.

This paper is about EO sensor module control based on the image processing. The main purpose of this research is acquiring a latitude and longitude of the target located on the ground by using image processing. For image processing, OpenCV is employed which is a computer vision library originally developed by Intel, and ATmega128 is used for the EO sensor module control. This task also involves realization of control programs and acquisition of sensor view angle for the position of the target.

Purpose: The purpose of this paper (a literature review study) was to confirm the trend of nursing research for head and neck cancer patients in Korea. Methods: Research databases were reviewed and analyzed from 13 papers (2004 through 2019 using KISS, NDSL, RISS, DBpia, and the National Assembly Library. As a result of this paper, we found that there were many studies that used questionnaires. Results: Measurement variables related to head and neck cancer patients were physical variables related to oral condition, psychological variables related to depression and anxiety, social support, family support related to family, and quality of life as a result variable. Conclusion: Therefore, integrated nursing intervention strategies and clinical nursing research considering the physical, psychological, social, and family aspects of head and neck cancer patients are needed. Based on the results of this study, we propose qualitative research on head and neck cancer patients, development of educational programs, intervention studies to verify effects, and development of clinical practice guidelines.
