This paper presents a design of a simulation apparatus to evaluate an operational control algorithm for the PRT system. PRT systems require very short headways to increase the line capacity and a very reliable vehicle control algorithm for avoidance of the impact between vehicles. Therefore, it can be said that the development of an reliable operational control algorithm for the PRT systems is much more important than that of the hardware configurations. In this paper an apparatus is proposed which is composed of virtual vehicles, a central control system, a man-machine interface and monitoring device, making it possible for the designed operational control algorithm to be implemented and tested. For the test of the proposed apparatus a test operational control algorithm is designed and the experimental results show the effectiveness of the proposed simulation apparatus for test and evaluation of the PRT operational control algorithms.

최근 급성 질환으로 인한 사망률은 꾸준히 증가하고 있다. 이러한 급성 질환은 초기 증상 발생 시 올바른 인지와 신속한 대처가 요구된다. 그러나 유지 관리비용 면에서 모든 개인의 응급상황을 관리할 수 있는 의료시스템은 구축하기 어렵다. 본 논문에서는 언급한 문제점을 해결하기 위해 웨어러블 디바이스와 개인건강기록 시스템을 제안한다. 웨어러블 디바이스에서 측정한 심박 체온의 생체신호로 응급 상황을 판별해 지정된 보호자에게 알린다. 또한, 응급버튼을 통해 곧바로 응급상황을 알린다. 개인이나 가족과 관련된 건강정보를 관리할 수 있는 개인건강기록(Personal Health Record)을 제공한다. 본 시스템을 통해 사용자의 응급상황에 신속하게 대처하여 생명을 보호할 수 있을 것으로 기대한다.

A post-processor is developed to be effectively usable in the personal computer. 3-dimensional controur lines are shown on the surface of the finite element model and also on the 3-dimensional cutting plane, using the function linearly interpolated onto the triangular elements which are constructed on the surface or sectional polygons. And these polygons are originated from the finite element model, 3-dimensional model is projected on the plane with hidden line removal by comparision technique[6]. The graphic data file is used to increase the protability of the program. It is easy to use in the other computer system if the graphic routine adopted that computer system is developed. The developed program has wide applications in 3-dimensional finite element analysis.

"언제, 어디에서, 어떤 형태의 접속"도 가능하게 하는 유비쿼터스 네트워크 환경의 실현을 위해 음성, 데이터의 통합은 우선 지원되어야 할 애플리케이션이다. 블루투스는 음성, 데이터의 동시 처리가 가능한 무선 개인 영역 네트워크(WPAN: Wireless Personal Area Network) 표준이다. 저가, 저전력의 무선 통신을 기반으로 휴대폰, 무전 전화기(Cordless Telephone) 의 음성 통화와 노트북, PDA 등의 정보기기의 인터넷 접속을 가능하게 한다. 본 논문에서는 블루투스의 음성, 데이터 통합처리를 구현한 블루투스 액세스 포인트(Access Point)에 대해 기술한다. 근거리 무선 데이터 통신과 유실 네트워크의 연결을 이루어 노트북, PDA 등 단말기의 인터넷 동시 접속을 지원하며 블루투스 폰의 VoIP 통화를 구현하였다. 개발 완료된 시스템의 테스트 결과 다양한 벤더들의 제품들과 호환성을 이루어 표준안을 만족하였으며 성능 면에서 역시 규격에서 제시한 최대치에 근접한 매우 우수함을 나타내었다.

The personal health record platform can store and manage medical records, health-monitoring data such as blood pressure and blood sugar, and life logs generated from various wearable devices. It provides services such as international standard-based medical document management, data pattern analysis and an intelligent inference engine, and disease prediction and domain contents. This study aims to construct a foundation for the transmission of international standard-based medical documents by mapping the diagnosis items of a general health examination, special health examination, life logs, health data, and life habits with the international standard terminology systems. The results of mapping with international standard terminology systems show a high mapping rate of 95.6%, with 78.8% for LOINC, 10.3% for SNOMED, and 6.5% when mapped with both LOINC and SNOMED.

This paper introduces that domestic animals can be effectively administered with an individual recognition system. The system was constructed in original code transmitter, receiver, personal computer, micro-processor, and RS485 telecommunications module. In the individual recognition system. the signal including encoded information about a milk-cow was transmitted from an original code transmitter to a micro-processor through RS485 telecommunications module. The transmitted signal was successfully displayed in a personal computer.

Recently, the automotive industry is being developed rapidly. On this, a demand of high quality performance­test­machine is increased too. But it is progressive technology that must be combined hydraulic, mechanic and electronic technologies. To construct this system, the design of oil hydraulic circuit, interface skill between sensor and personal computer, data acquisition & display system and integrated control are very important skill. Moreover, reliable data is obtained with vacuum system and complex heat exchange system. Therefore, in this study, we designed a performance­test­machine by using above key technologies and we also made a integrated PC control system using personal computer which is more progressive and flexible method than PLC control.

In this paper, a small, lightweight smartphone-controlled riding robot is developed. Also, in this study, a smartphone with a jog shuttle mode for consideration of user convenience is proposed to make a small, lightweight riding robot. As well, a compass sensor is used to compensate for the mechanical characteristics of motors mounted on the riding robot. The riding robot is controlled by the interface of a drag-based jog shuttle in the smartphone, instead of a mechanical controller. For a personal riding robot, if the smartphone is used as a controller instead of a handle or a pole, it reduces its size, weight, and cost to a great extent. Thus, the riding robot can be used in indoor spaces such as offices for moving or a train or bus station and an airport for scouting, or hospital for disabilities. Experimental results show that the riding robot is easily and conveniently controlled by the proposed smartphone interface based on Android.

본 논문에서는 PAV 추진기관에 대한 현황 및 전망을 조사하고 검토하였다. 현재의 수송교통 체계가 포화상태로 가고 있기 때문에 그 대안으로 개인용 항공기(PAV, Personal Air Vehicle)의 출현이 강하게 요구되고 있다. 왕복엔진의 경우 효율과 가격의 측면에서 우수하다는 장점을 지니고 있어 큰 출력을 필요로 하지 않는 PAV에 적합하다고 생각할 수 있다. 최근 친환경 시장이 급격히 성장하고 있어 기존 왕복엔진이나 가스터빈엔진 기술의 발전과 더불어서 연료전지와 배터리를 이용하는 친환경적인 추진기관을 선호하는 추세가 높아지고 있다.

The purpose in this study is to identify beliefs about curriculum orientation of Korean secondary school home economics teachers for the development of home economics curriculum and the change of their curriculum orientation. The curriculum orientations explored were academic rationalism, technical, cognitive process, personal relevance, and social reconstruction. A mail questionnaire, Individual Curriculum Orientation Profile (ICOP), was used to survey randomly selected 525 home economics teachers. Home economics teachers agreed with the cognitive process as their predominant curriculum orientation. The second predominant type with which home economics teachers agreed most was personal relevance orientation. Home economics teachers’age, major, college type, and teaching years were significantly related to the academic rationalism curriculum orientation, and the college type for bachelor’s degree was significantly related to the technical curriculum orientation. Age and major in master’s degree were significantly related to the social reconstruction curriculum orientation.
