This research knowledge and practice about a patient's oral health and oral hygiene related quality of life you want to measure the impact of oral health impact assessment, one of OHIP was evaluated by using the. The results are used daily in prevention knowledge and everyday knowledge, and how to use knowledge of dental supplies highly subjective feel the higher quality of lift. And with medical knowledge and experience, acquired knowledge OHIP higher the lower the quality of lift according to the subjective feel. Meanwhile, one of the whitening treatment aesthetic appreciation treatment higher subjective knowledge feel the higher quality of life. This means that knowledge of preventive oral health and aesthetic impart is expected to affect the index.

This research is to find out the method appropriate for the forecasting of passennger demand using seasonal ARIMA model and efficient operation in Jeju National Airport. Time series monthly data for the investigation were collected ranging from January 2003 to December 2011. A total of 108 observations were used for data analysis. Research findings showed that the multiplicative seasonal ARIMA(0.1.2)(0.1.1)12 model is appropriate model. The number of passengers in Jeju National Airport will continue to rise, it was expected to surpass 20 million people.

A proposed system can decrypt each contents block through a double buffer algorithm which can continually buffer contents by dividing a multimedia contents into some blocks and provides more improved method of encryption than existing system by being not capable of decrypting the whole multimedia contents if one key is exposed. Also, using digital signature and public encryption algorithm for mutual authentication between systems, this paper proposes the system which sends and encrypts symmetric keys for contents encryption through SOAP messages.

Three-party authenticated key exchange protocol based on smartcards using XOR and hash function operation instead of the public key operation has been proposed in 2006. Recently, it is doing for research because of increasing interest in privacy. This paper pointed out that proposed three-party authenticated key exchange protocol in 2006 has some problems; it is user anonymity and slow wrong input detection, and then we proposed new one to overcome these problems.

Education is important in Korea and English education takes a huge part of it. Korean Education can be divided into public and private. A number of households expend money on private education. Therefore this study examines the relationship between private education expense and the grade of college entrance examination. As results, there is a positive effect between them and also a positive effect between the total mount of time of private education and the grade of college entrance examination.

Ubiquitous environment is expected to be result of researches and studies in ubiquitous home base on. However, because of the complexity of the ubiquitous home base on, the realization of error handling seems impossible. In this paper, we present how to detect and recover from these errors for the Ubiquitous Home utilizing a fault simulator developed for the study and through a variety of experiments, results were discussed and analyzed. Base on the said results, future works are also discussed.

The demand of bike increases eco-friendly as the mean of transportation but domestic production basis becomes sluggish. In this study, the design analysis of horizontal and vertical frame is performed on the model which is proposed as the bike of new concept in conjunction with public transport system. As the result, the structural analysis is conducted on the main frame of urban bike used with cast magnesium alloy. As the vertical load of 150 kg is applied, the design technology insures that maximum stress less than 70 MPa is obtained.

In this paper, we propose a lightweight mutual authentication protocol for secure and efficient home network service. Lee et al. recently proposed an attribute-base authentication key agreement protocol using public key in home network. Its protocol provided forward secrecy but don't diminish conspicious overhead of operation using ticket. Therefore the proposed protocol provided the security and efficiency using hash function and counter. Also it can provide secure home network service by check consumer electronics control level of users after created session key.
