Due to the miniaturization and the network supporting functions of home appliances, there is growing need for mobile environment home network system which provides flexibility, mobility and convenience to users. In this environment, a interactive authentication between mobile devices is important but the related works have no enough convenience to users. This paper proposes a interactive device authentication mechanism using Home Robot and also shows its design and implementation.

Since the advance of WWW, internet related fields have been growing very rapidly. Especially, the development of electronic commerce ares have changed even or life style. This paper is about the design and implementation of an internet auction system, which is considered as on of the most attractive internet services. An internet auction system has more complex processes compared with other electronic commerce systems. In auction systems, bids and a successful bid are required in trading all goods. In this paper, I designed and implemented all processes of an internet auction system, in which a bid tracing systems is included for the first time. The bid tracing system is implemented using only HTTP in maintain compatibility in WWW environment. I also used th JAVA blocking concept to simulate two-way communication. The proposed system is implemented on Windows NT environment using JAVA, ASP, and the Oracle database.

With the global climate changes, a global concerns on building energy uses and $CO_2$ emission to improve the environment friendly has been increasingly growing. To achieve this global goal, the Korea government has been seeking an environment-friendly and sustainable development. As the results, the government started Green Building Certification Criteria system. however the certificate system has still been at the basic stage. To upgrade and advance it's level, it's necessary to identify the current status. This study aims to pick out the items requiring improvement for the Ecology of Education Facilities. We expect that the results of this study will be helpful for the next design works of certificate system.

The computational modeling and simulation of complex biological systems are indispensable for new knowledge extraction from huge experimental data and ever growing vast amount of information in systems biology. Moreover, gathering and sharing of the existing information and newly-generated knowledge can speed up this research process. In this regard, several modeling projects have been undertaken for quantitatively analyzing the biological systems via the internet. They include Virtual Cell, JWS and OBIYagns. We also develop an integrated web-based environment, which facilitate investigation of dynamic behavior of cellular systems.

The recent broadcasting environment has shifted to embrace multimedia and multi-channel features through terrestrial, satellite and cable media. This has multiplied the number of broadcasting programs. With the information on a myriad of programs provided to TV viewers, information overload occurs, and thus, the TV viewing environment is shifting to one where viewers cannot select programs passively. Thus, a growing need is emerging to ensure a personalized electronic program guide (EPG) to help individuals select TV programs according to their taste. This paper presents a personalized EPG that enables a purpose-oriented broadcasting service to provide personalized broadcasting programs in tune with the user's requirements and preferences.

As cognizance of necessity of environmentally friendly building is growing, techniques to construct environmentally friendly envelope of contemporary architecture is being changed and developed. Though the stream of times likes this, applications of those are focused on office buildings but rarely on residential projects. A begin of this study is to address analysis of environmentally friendly envelope techniques in urban housing in Europe constructed after 1995 which is the very time that the notion of ecological architecture. The result of this analysis should be a suggestion of radical data to make buildings be more buildings be more environmentally friendly and having amenities.

Twenty-one lowland rice genotypes were evaluated for their stability parameters with respect to grain yield in a multi locational trial at five different sites of Eastern India viz. CRRI, Cuttack (Orissa); OUAT, Bhubaneswar (Orissa); CRS, Masodha (UP); RAU, Pusa (Bihar) and RARS, North Lakhimpur (Assam). Pooled analysis of variance reflects existence of genotype x environment interactions and contribution of both linear and nonlinear components to genotype (G) x environment (E) interactions. Through stability parameter analysis it was found that Rayda $\textrm{B}_3$, CR 778-95 and CR 661-236 were suitable for over all environments where as Sabita, OR 1334-16 and OR 1358-RGA-4 were suitable for rich environments. PSR 1209-2-3-2, CR 780-1937, Ambika, OR 877-ST-4-2 and CR 662-2211 were identified for poor environments.

Since the world entered the age called "Smart Revolution", there has also been a lot of changes in the field of education. In educational environment, there is a growing interest in smart learning based on mobile contents, with the development of Smart Devices and ubiquitous technology. This paper is about a research on what effects smart learning has on leaner side when learners make active use of mobile contents in this age of Smart Revolution. First, we embodied teaching plans for some practical classes in forms of mobile contents using M-bizmaker. After the learning process based on the embodied contents for students, we analyzed the survey results on 4 sections-their use of apps, screen composition, technical support, interactions. We also studied the results of a questionnaire on 4 sections-contents, information offering, feedback systems, learner assessment-to evaluate their satisfaction. The research suggests that learner satisfaction can be improved with smart learning based on mobile contents embodied for leaners.

Since the appearance of the first computer virus in 1986, a significant number of new viruses has appeared every year. Recently, there has been a marked increase in the number of mobile malicious code(virus, worm, trojan) in Mobile devices(smart phone, PDA). As a growing number of people use mobile device, we have to prepare for coming mobile attacks. In this paper, we study trends and characteristics of mobile malicious code. And, we describe considerations of on-device and network security in mobile environment.

The polycrystalline 3C-SiC thin films heteroepitaxially grown by LPCVD method using single precursor 1. 3-disilabutane at $850^{\circ}C$. The crystallinity of the 3C-SiC thin film. was analyzed by XPS. Residual strain was investigated by Raman scattering. The surface morphology and voids between SiC and $SiO_2$ were measured by SEM. The grown poly 3C-SiC thin film is very good crystalline quality, surface like mirror, and low defect and strain. Therefore, the polycrystalline 3C-SiC is suitable for harsh environment MEMS applications.
