The object of this study is to build service model that combines developing IT technology with construction filed. It combines existing traditional construction project with high-tech IT choosingly, diverting construction project from labour-intensive to value-added technology-intensive industry. By doing so, it plans improving productivity and creation of new market. Now most ideal field of combining construction with IT technology is U-City industry that is being emphasized recently. Therefore, For this study, We analyze present condition of several IT technology used in construction and U-City project. Also, determining priority of promising IT technology for requirement analysis of consumer. And it proposes plan for construction of U-City service model through prospect and environment analysis of U-City and IT industry.

u-City is a new concept and phenomena of applying Information & Communications Technology(ICT) into real cities in Korea. In order to effectively integrate a city with high-tech ICT infrastructure, cutting-edge ICT is being integrated into physical urban environments from the planning and construction stage of a city. There are positive expectations regarding its effect on urban planning and citizens' lives. However, construction of u-city has technical limitations as well as institutional obstacles. This paper aims at identifying problems of current u-city practices and suggesting appropriate solutions for those problems. To do so, it first collects opinions from diverse experts. Then, it draws problems and suggests solutions in terms of u-infrastructure, u-service, policy and implementation process.

본 연구는 u-City에서 제공하는 u-서비스의 새로운 수익모델 창출을 위한 접근 방안으로 사용자 중심의 접근을 시도 했으며 u-서비스에 사용자가 부여하는 가치에 중점을 두고 연구를 진행하였다. 사용자가 부여한 가치의 확장을 통해 새로운 서비스 또는 수익모델 창출의 기회를 발굴하고자 하였다. 연구 결과 사용자가 부여하는 1차적인 가치는 서비스와 관련된 다양한 가치로 그 의미가 확장될 수 있었다. 확장된 가치를 근간으로 기존에 고려하지 못한 새로운 서비스와 수익모델을 발굴할 수 있는 기회를 포착할 수 있었다. u-서비스의 수익모델 창출을 위한 새로운 접근 방안으로써 사용자 가치에 대한 고려는 실질적으로 서비스를 사용할 사용자에 기초한 관점으로 사용자 중심의 u-서비스 개발 및 수익모델 발굴에 중요한 연구가 될 것이라 생각된다.

The fast-paced development in the field of U-Healthcare, which is available anytime and anywhere, is being underway in accordance with the development of IT technology. U-Healthcare technology has various security threats because it is based on network. The purpose of this paper is to examine the threats of DOS / DDOS attacks based on network attacks, and to propose the response technique that fit the situation of the U-Healthcare service by modifying the existing Detecting Early DOS / DDOS attacks through Packet Counting.

KUbiquitous city(U-City) is a recent trend in urban planning and management across the globe. Currently, several typologies were developed and presented classifying U-City services, but validation research of these typologies are scarce. In this study, efforts were made to qualitatively validate the usability and practicality of a typology of u-city services. Using 228 U-City services identified in previous studies, classifying exercises were conducted against a typology. Three experts were involved in this expert heuristic exercise, against a most popularly used and comprehensive typology of U-City services. Findings indicates that the selected typology is high on comprehensive exhaustiveness, and empirical applicability while low on mutual exclusivity, simplicity and theoretical contribution. Implications for the typology improvement are suggested followed by limitations and directions for further research.

In this paper, I described a guide of developing contents to present the direction of developing contents for u-learning. After surveying a character of Ubiquitous computing and u-learning, I described a guide of developing contents which is composed 17 items in 5 fields. This guide is checked by experts and staffs to test a validity and reliability. As a result, It is proven having the validity and reliability. I expect it to guide the direction of developing contents for u-learning. Also, It will contribute to make effective contents which will not affected by technical development and can use continuously because of foreseeing the technical development of future.

u-T (ubiquitous transportation) environment can be envisioned as an advanced version of ITS environment and be expected to provide more advanced transportation service in a ubiquitous manner. As a basic necessity to measure traffic flow in both environments, a flow estimation method was proposed. Flows have been measured in existing ITS and in a new u-T environments and some differences were investigated using simulation technique. In the interrupted traffic situation, the flow rate of u-T is 3.58% higher than that in ITS environment. Both MARE and MAE, which were used as measure of effectiveness, in u-T were better since the results are 31.4% and 31.1% lower than in ITS, respectively. Besides the equality coefficient in u-T was 1.9% higher than that in ITS. Such being the case, the flow rate measured in u-T using U-TSN is more reliable and can be expected to be successfully used for transportation system design or traffic operation areas.
