        Uganda is a country blessed with the biggest number of mountain Gorillas in the whole world. These animals contribute at least 12% in revenue generation to the Tourism sector through tracking by both local and foreign tourists who pay for the tracking permits. However, Gorilla tracking is also a big challenge even in the presence of highly skilled and well-trained game rangers. Development and implementation of a secure Computer and Mobile based Gorilla Tracking (GT) system that uses GIS and GPS technologies would be the most ideal technology to use. Therefore, this study aimed to find out the critical factors that would affect the Behavioral Intention of the would-be users to successfully decide to use such GIS/GPS-GT system. We used the existing UTAUT model to integrate six factors such as Performance Expectancy, Effort Expectancy, Employee Peer Influence, Facilitating Conditions, Behavioral Intention and System Use. However, Infrastructure Availability and Non-Technical Facilitating Conditions were added to reflect Ugandan ICT context. This amended UTAUT model was used to carry out the survey. The questionnaire was emailed to 220 government employees in the fields of ICT, Tour and Travel, Environmental Groups officials and Farmers who garden near the game reserves. A total of 133 were obtained fully completed, whereas 127 were deemed usable thus yielding a response rate of 58%. The analysis results show that except for non-technical facilitating conditions, effort expectancy, peer influence, performance expectancy and infrastructure availability positively affects behavioral Intention to use GIS/GPS-GT. This indicates that people in Uganda don’t bother about regulations and rules in regard to using information system. As long as the system does what they want it to, anything else does not matter. As an employee in an organization is told to use a system by their supervisor, they have no objection to otherwise they risk losing their job. This implies that, supervisors have a great responsibility in the process of developing, implementing and using the system in Uganda.

        The Internet, as a general utility for carrying information and communication technologies, provides a vehicle for the unprecedented availability of information. The global proliferation of the Internet and the increasing speeds of transmission mean that information is available anywhere in world, at the time and place of one’s choice, and in a manner that encourages individual exploration (Tomlinson-Keasey, 2002). For educators, information and communication technology (ICT), including the Internet, holds the promise of not only greater access but also higher quality learning materials provided to students at a lower cost, coupled with the possibility of a more learnercentered paradigm of instruction. Meanwhile, technological and economic development has placed greater demands on education systems in many countries, calling for people who are more adaptable to change, more innovative and creative, and better able to apply their knowledge to solve complex problems. Are Asian and Pacific countries meeting these challenges? This UNESCO publication, Integrating ICT into Education, clearly supports the claim that ICT has been embraced in education, at least in the six economies examined, and has made an impact on education systems. A wealth of experiences, good practices, and lessons has been generated for the benefit of others in the region. The purpose of this book is (1) to describe lessons learned in integrating ICT programs based on based on the experiences of six Asian countries— Indonesia, Malaysia, Korea, the Philippines, Singapore, and Thailand—and (2) to synthesize and analyze ICT integration experiences in connection with specific lessons learned and highlight best practices and the need for further improvements.

        등온용량과도분광법(Isothermal Capacitance Transient spectroscopy)을 이용하여 ZnO 바리스터의 포획준위를 결정하였다. 여기서 등온용량과도분광기는 YHP 4192A 임피던스 Analyzer와 데이터해석을 위한 개인용 컴퓨터로 구성된다. 이 실험에서 우리는 ZnO-Bi2O3에 MnO 및 CoO를 첨가한계에서 -40˚C~60˚C 온도범위에서 0.28, 0.48, 0.50, 0.94eV 등의 입계포획준위가 존재함을 볼 수 있었다. 또한, ZnO-Bi2O3계는 CoO를 첨가하면 hole에 의한 emission특성을 나타내고, MnO를 첨가하면 전자에 의한 emission특성을 나타냄을 알 수 있었다. 그리고 비 직선저항계수 α는 도너농도의 감소에 직접적으로 비례하였으나, 포획준위의 밀도와는 별다른 비례관계를 발견할 수 없었다. 결론적으로 ZnO-Bi2O3-MnO계에 CoO를 첨가함에 따라 α값이 증가하는 한편, 포획준위밀도는 CoO의 첨가로 감소함을 알 수 있었다.

        화학증착법에 의해 Si3N4-TiC 복합재료 위에 코팅된 TiC 박막은 TiN 박막에 비하여 우수한 미세구조와 열충격저항, 계면결합을 가지고 있는 것으로 나타났다. 화학증착법에 의한 TiN 박막은 TiC 박막에 비해 강철과의 마찰계수가 작고 화학적으로 안정하였다. 실험결과는 코팅된 절삭공구가 우수한 내 마모성을 갖고 있는 것으로 나타났다. 또한, 다중 코팅된 절삭공구는 단일 코팅된 공구보다 우수한 내 마모성을 보였다.
