This research proposes the U-drawing information system (U-DIS) based on risk assessment. One of the most outstanding features of U-DIS is to perform the Quantitative Risk Assessment directly on the screen utilizing the Process Information. U-DIS revolutionizes the existing way to do a risk assessment and helps finding information more efficiently and simply. It is designed to open all CAD drawing files on the web-based environment without having the CAD S/W installed on the PC. The U terminal platform in U-DIS supports IPv6 and wireless broadband network and U-DIS can be accessible through a sensor or personal authorization. This results in providing a systematic safety enhancement tool considering not only the operation of the process but also its risk level in the equipment industry. Additionally to aid the decision making process it offers comprehensive and thorough information based on engineering technical theory.

After the IMF jurisdiction period, the Korean economy experienced a venture boom. Korean venture enterprises had been recognized that high profitable and high technology capacity based. These ventures also have contributed to national added value tolerably. In particular, Korean information technology (IT) venture companies got away the order of economy concentrated big companies, which were taken the opportunity of new economy to make suggestion of the future courses and to open an e-Korea era. However, IT ventures firms or dotcom enterprises have had difficulties through sinking down their bubbles and slumping technology sector from the first half of the 2000. In consideration of Korea IT venture companies' conditions, Korean government introduce new national vision in order to go ahead of intelligence based society form knowledge based. Korea is planning new investment to meet with the challenge of globalization proactively by national band named u-Korea. As following a step in IT infrastructure, it will give Korean IT ventures new demand creative technologies and services by new technological windows of opportunity. This situation is expected that will become an economic take-off. This paper will look for the way to stimulate Korean IT ventures' competence and present new frontier of IT ventures turnaround.

Due to the convergence between digital devices and the development of wireless communication technology, bit-signal sensor miniaturization, building an Electronic Medical Record (EMR) which is a digital version of a paper chart that contains all of a patient's medical history and the information of Electronic Health Record (EHR), Ubiquitous healthcare (u-Healthcare) that can monitor their health status and provide personal healthcare service anytime and anywhere. Also, the appearance of cloud computing technology is one of the factors that accelerate the development of u-healthcare service. However, if the individual information to be used maliciously during the u-healthcare service utilization, leads to serious problems directly related to the individual's life because if it goes beyond the level of simple health screening and treatment, it may not provide accurate and reliable healthcare services. For this reason, we analyzed a variety of security issues related to u-healthcare service in cloud computing environment and described about directions of secure health information sharing system construction. In addition, we suggest the future developmental direction for th activation of u-healthcare industry.

As our country is currently facing "aging society," people demands for qualitively and quantitatively better social welfare services. In particular, the abruptly rapid increase in the elderly population requires various welfare services and medical care related to the elderly. It is urgent to resolve these demands. Also, IT technology in Korea is developing rapidly, and U-Health, a part of the Ubiquitous field is under the actively ongoing researches. In this paper, we studied the Elderly care system model suing U-Health technology. We designed the care system of the residential environment designed specific for the elderly. Additionally, based on that design, we studied the elderly care system using the ubiquitous technology. Since this elderly care system combines the existing community-based model and IT technology in conjunction with other mobile devices, we may supply a new care service application, thus solving the problems of the existing care and medical services.

In this paper, the u-Service system that is based on location-aware technology is designed and implemented for a silver town. On the real silver town the developed system has been employed and tested to provide convenient and secure living for residents. It provides services such as emergency call, intelligent elevator operation, and hands-free door access based on the location of the residents with personal device as called smart tag. It can also be applied to other service areas such as the location-aware u-Service for hospital, high-rising complex building, APT, etc.

The emergences of GeoSensor and researches about GIS have promoted many researches of u-GIS. The disaster application coupled in the u-GIS can apply to monitor accident area and to prevent spread of accident. The application needs the u-GIS DSMS technique to acquire, to process GeoSensor data and to integrate them with GIS data. The u-GIS DSMS must process big and large-volume data stream such as spatial data and multimedia data. Due to the feature of the data stream, in u-GIS DSMS, query processing can be delayed. Moreover, as increasing the input rate of data in the area generating events, the network traffic is increased. To solve this problem, in this paper we describe TRIGGER ACTION clause in CQ on the u-GIS DSMS environment and proposes data source management. Data source weight table controls GES information and incoming data rate. It controls incoming data rate as increasing weight at GES of disaster area. Consequently, it can contribute query processing rate and accuracy

In this paper I propose the semantics of two modality markers in Korean, keyss and (u)1 kes. I compare the two modality markers with respect to some properties. First, keyss is used to express logical necessity while (u)1 kes can be used to express a simple prediction as well. Second, keyss expresses some logical conclusion from the speaker's own information state without claiming it is true. On the other hand, (u)1 kes expresses the claim that the speaker's prediction will be true. Third, the prediction of keyss is non-monotonic: it can be reversed without being inconsistent. However, that of (u)1 kes cannot. Fourth, (u)1 kes can be used freely in epistemic conditionals, but keyss cannot. Finally, when keyss is used, the prediction cannot be repeated. The prediction from the use of (u)1 kes can be repeated. To account for these differences, I propose that keyss is used when the speaker makes a purely logical presumption based on his/her own information state, and that (u)1 kes is used to make a prediction which is asserted to be true. This proposal accounts for all the differences of the two modality markers.
