This paper describes the characteristics of emissions and fuel economy of soft type hybrid vehicle (Hyundai Avante) and hard type hybrid vehicle(Toyoda, Prius) in a transient CVS-75 driving mode. Hybrid vehicles showed the better fuel economy and emission characteristics comparing the conventional gasoline vehicle. Especially, hard type hybrid vehicle showed the better fuel economy comparing soft type hybrid vehicle under 55 km/h periods in the CVS-75 mode.

The demand for Mobile Web Services has increased to overcome the issue of Mobile Application's platform dependencies and device resource's limitations. The method to improve productivity of the development and operation of the Mobile Web Services is to provide a low-coupling between Mobile Webs. In this paper, we propose the Recommendation Technique of dynamic Mobile Web integration to reduce the coupling. The Mobile Web Recommendation Technique is proposed based on XPDL.

This study focuses on the growth and development of small and medium industries of Korea, orienting to the development of up-to-date technology from now on and bolstering their competitive ability in the rapidly changing international markets. For this purpose, the small and medium industries should 1) develop high-level manpower of up-to-date technology, 2) make constant efforts to categorize and divide the fields of technology with big business groups to boost their competitiveness, 3) raise automation rate by turning all facilities into mechatronics, 4) positively develop software know-how, 5) jointly conduct researches in cooperation with venture capital and Governmental research institute, 6) categorize an systematize the industries. On the Governmental level, there should be 1) wide-ranging support and assistance in technology, finance, and the facilities, 2) positive opening of consumer market, 3) assistance in technical cooperation with other nations, 4) and such indirect assistance as fostering the fields of related technology.

Since 2000, S. Korea is building yachts through government supported localization, cooperation between industry and educational organizations, or partnerships with foreign firms but the yacht building has yet only accomplished trial manufactured ships and one-time production. Because of a lack of mass production, the industry assesses the domestic technical skills to an average 50~60% of developed countries and its market share is less than 1% in the world. In addition, domestic marine equipment is heavily depending on imports and the industry is experiencing shortage of technology and experts, small-sized companies, insufficient industry and educational organizations' cooperation networks, inadequate legislation and policies, deficient domestic market vitalization, and scarce international information. Thus, this study focuses on the alternative plans to strengthen competitiveness and to cope with problems in the southeast marine leisure equipment industry.

To make practical application of mixing test results to concrete mix design, experimental tests of concrete were done and the relationship between cement-water ratio and compressive strength of concrete was obtained. A computer program which can be used for data base of air content, slump and compressive strength test results was developed. The program draws $\bar{X}$-R or X-Rs control charts and has data sheets for arrangement of material test results. The computer program also helps calculation of concrete mix proportions for mixing tests and contains dictionary of concrete technical terms.

The keen global competition is expected among foreign advanced nations for source, key technologies required by unmanned combat ground vehicle. Therefore, the trend of technologies for unmanned ground combat vehicle was analyzed in this research. It was based on the submitted patents from 1988 to 2008 in Korea, U.S.A, Japan, Europe, Canada and Israel. This analysis was focused on finding the technical level, the challenge area and breakthrough technologies and the growth of technologies of each nations considering opinions of experts. This report suggested the field of key technology development

The developed system is captured by RS-232 telecommunication receiving data (temperature and humidity of each incubator) through radio frequency sensor network system and is made by monitoring system for one person collecting each channel data. This monitoring system is capable of monitoring not only PDA through TCP/IP telecommunication but also personal computer. This system is actively application on telecommunication function of LabVIEW and PDA module and is considerably saved in processing time than using in other tools.
