In this paper, an Embedded solution for fast navigation and precise positioning of mobile robots by floor features is introduced. Most of navigation systems tend to require high-performance computing unit and high quality sensor data. They can produce high accuracy navigation systems but have limited application due to their high cost. The introduced navigation system is designed to be a low cost solution for a wide range of applications such as toys, mobile service robots and education. The key design idea of the system is a simple localization approach using line features of the floor and delayed localization strategy using topological map. It differs from typical navigation approaches which usually use Simultaneous Localization and Mapping (SLAM) technique with high latency localization. This navigation system is implemented on single board Raspberry Pi B+ computer which has 1.4 GHz processor and Redone mobile robot which has maximum speed of 1.1 m/s.

The rapid exchanges of mobile computing environment and development of wireless communication are providing many effects for learning activity of students. Recently, PDA system developers which are studying memory capacity, communication speed and size of screen support techniques to be capable of learning from students in the wireless or moving environment. In this viewpoints, this paper has a purpose to design multimedia learning system to be able to do with sound lecture contents. The implemented system largely consists of two parts which have the teacher module and students module. The one manages learning progress of students, class management, bulletin board and etc. The other is capable of using studying and bulletin functions. The main idea of this research is focus to upgrade the effect of learning without almost treating the existing studies, which can be listening sound lecture and also seeing text and image at the same time.

본 논문은 8051 마이크로프로세서의 내부 코아 특성과 시스템 재사용에 대한 통합설계 방법을 사용하여 하나의 시스템을 제작하였다. 또한 이 시스템을 독립적으로 사용할 뿐만 아니라 다른 시스템의 모듈로서 사용할 수 있도록 시스템을 설계 및 구현한다. 제안된 방법에서 재사용이 가능하도록 시스템 자체를 객체형으로 구현하고, 시스템들 간의 연결을 위해 객체형이 구현된다. 이러한 객체형의 요구에 맞추어 시스템들이 자기정보를 가지고 다른 시스템들과 연결되었을 때 자신의 정보를 제공함으로써 자동 인식되고, 시스템 자체가 다른 시스템에 재 적용될 수 있도록 한다. 본 논문에서 제안된 방법은 기존의 Z-80 계열의 교육용 제어보드와 비교 분석하여, 제안한 시스템이 확장성의 효율성을 제공할 뿐만 아니라, 대부분의 기능을 소프트웨어로 처리하여 개발 기간, 비용 및 보드 크기가 축소되는 등의 장점을 입증하였다. 또한 객체형 시스템 아키텍처로 설계하여 확장성과 이식성이 증대되는 특징을 보였다.

Expansion and spreading of marine telemedicine is rather restricted due to the conflict of laws relating to medical service and lack of provisions in the Seafarers' Act, Medical Service Act, etc. Thus, this study is intended to reveal the current status and problems of marine emergency medical advice system for the furtherance of health care of seafarers and emergency medical assistance conditions and deduce relevant proposals for legislative improvements thereof in order to resolve underlying problems and issues. The results of this study can be summated as follows. First, in respect of directions to provide marine emergency service based on marine telemedicine system, emergency radio medical advice system needs to be strengthened to meet domestic and international instrument, marine telemedicine system needs to be provided through integrating u-Health technology and special marine medical center needs to be established. Second, regarding directions to provide health promotion service based on the marine telemedicine system, a new process of health care service for seafarers needs to be devised and provided involving seafarers' life cycle covering from prior to boarding to after leaving a ship. The conclusions of this study can be given as follows. First, the following new provisions need to be introduced in the Seafarers' Act. (1) The Minister of Oceans and Fisheries and a shipowner shall conduct matters pertaining to preventive health promotion and care for seafarers; (2) a provisions regarding establishment of seafarers' health promotion center by the Minister; (3) a special exemption permitting marine telemedicine service and qualification requirements for marine telemedicine assistant; (4) shipowner's obligation of carrying seafarers' health measuring equipment on board. Second, the relevant provisions regarding medical care persons needs to be revised in such a way that master or chief officer shall be appointed to be in charge of medical care on board. Last but not least, it is also essential to amend and update the minimum standards on drug and medicines to be carried on board and medicine chest and equipment on board.

The goal of the military medicine is not as same as that of the civil medical practice, and consequently the characteristics of military biomedical researches have their own uniqueness. In front of the prerogative of national defense, some of the human rights ordinarily ensured in normal researches with human subjects are not to be fully guaranteed. The hierarchic system of the military would complicate the issue when the soldiers are enrolled as human subject for the research. Some researches could be classified as a military secret, therefore, the confidentiality issues need to be well addressed. Institutional Review Board and review procedure should be modified for the military purposes. So, it is necessary to establish the appropriate regulatory system for the military biomedical researches with human subject to manage the complicated issues involved in them.

In this paper, we implemented a web-based virtual laboratory system(VLab system) with creative and interactive multimedia contents, which can be used to enhance the quality of education in the area of digital logic circuits. Since the proposed VLab system is implemented to describe the on-campus laboratory, the learners can obtain similar experimental data through it. Also, the VLab system is designed to increase the learning and teaching efficiencies of both the learners and the educators, respectively. The learners will be able to achieve high teaming standard and the educators save their time and labor. The virtual experiments on our VLab system are performed according to the following procedure: (1) Circuit composition on the virtual bread board (2). Applying input voltage (3) Output measurements (4) Checkout of experiment results. Furthermore, the circuit composition on the virtual bread board and its corresponding online schematic diagram are displayed together on the VLab system for the learner's convenience. Finally, we have obtained several affirmative effects such as reducing the total experimental hours and the damage rate for experimental equipments and increasing learning efficiencies as well as faculty productivity.
