The purpose of this is to examine the relation between tourist motivation and attribute of attractions closely. The tourist motivationmade a practical application of the functional theory, which is one of the theories explaining an attitude and a change in attitude, and was catagorized. The three distinctive repondence cluster was composed of this tourist motivation, ans each cluster is considered to have the characteristics of many coessential tourist motivation. So we tried to make an analysis to importance of attitude of attraction which each cluster seeks after. The potential tourists, who have the utiliarian motivation, are in pursuit full of the natural attributes, but in the fewest of the cultural attributes. The potential tourists, whe have knowledge motivation, are in full of pursuit of the cultural attributes, but in the fewest pursuit of the attributes of attractions such as low price and convenient transportation.

본 논문에서는 UWB(Ultra Wide Band) 다중 경로 채널에서 PRAKE(Partial RAKE) 기법을 이용한 시간 도약 다원 접속 시스템의 간섭 제거 기법을 제안한다. 제안된 간섭 제거 기법은 다중 사용자 간섭(MAI)의 효율적인 추정을 위하여 매 프레임마다 보호 구간을 적용하는 기존의 전송 방식과 달리 슬롯 단위의 보호 구간을 적용한 전송 모델을 사용한다. 일반적인 UWB 시스템이 다중 경로 채널 환경에서 심볼 간 간섭(ISI)과 다중 사용자 간섭에 의하여 사용자의 수에 따라 심각한 성능의 저하를 가져오는 반면, 제안된 간섭 제거 기법을 적용한 UWB 시스템은 사용자 수에 관계없이 일정한 성능을 보인다. 또한 시스템의 복잡도를 줄이기 위하여 본 논문에서는 간섭을 제거한 신호에 대한 PRAKE 결합 기법과 부분 사용자 간섭 제거를 이용한 저 복잡도 간섭 제거 기법을 제안한다. In this paper, we propose an interference cancellation(IC) scheme using a partial Rake(PRAKE) combining in ultra-wideband(UWB) multipath fading channels. In this IC scheme, differently from the conventional transmitter model, which employs a guard interval between each frame, the guard interval is employed between each slot for estimating the multiple access interference(MAI). The UWB systems using the proposed IC scheme have little performance degradation without regard to the number of user, while the conventional UWB systems have a significant performance degradation according to the number of user. In order to reduce the receiver complexity, the PRAKE combining of post-canceled signal and the partial user IC scheme are also proposed.

The objective of this study is on evaluation process of resort hotel management strategy. Therefore, in this study, we find try to a successful implemantation of resort hotel feasibility study and management strategy by systematizing and materialinzing the theory of resort hotel. And we have also investigated and analyzed the real status of resort hotel and then worked out the problem, and estabilished a plan for feasibility determination of resort hotel, he results of this study are as follow: 1) We need to characterize, matenance, develop the benefits of resort hotel. 2) We need to know how to establish model and facilities of resort hotel. 3) We have to inclease quality and quantity of employee's service. 4) We need to effort to satisfy customer's needs and wants through improvising and enlarging facilities of resort hotel. 5) We need to specialize the quality of F & B division. 6) We need to improve the hotel image, promote sales through promotion tools like avertisement, publicity, personel selling, sales promotion.

Health care systems or Hospital Information systems have accumulated a lot of amount of medical data. The naive feature set might have noisy or redundant features. The performance of complex model for the initial data can deteriorate, since the naive data set might have noisy or redundant features and they require a lot of resources and time for computation. To Challenge this problem, We applied a series of feature selection(FS) techniques to the prediction of the modified Rankin Scale (mRS), which is a measure of the daily activity disorder of people suffering from stroke, using the 8 famous FS. The experiment compared the performance of classifications with FS algorithms using stroke data set that is supposed of 81 representation features for stroke. Experimental results show that, Random Foest(RF) classification with a filter based for FS using of f-score and t-score performed best in accuracy. It was also demonstrated that Genetic algorithm(GA) with RF produced the most effective set in the 3 wrapper methods. GA with RF produced the most effective feature set for mRS prediction, This can have almost the same accuracy with 69.6% less model learning time than all features.

Nail-patella syndrome is a relatively rare autosomal dominant disorder characterized by dysplastic nail, hypoplastic or absent patella, and dislocation of radial head and iliac horns. In addition, renal abnormalities have been reported. The usual clinical signs of the renal involvement are asymptomatic proteinuria, microscopic hematuria, and in some cases progression to end stage renal disease. We present the case of adult with nail-patella syndrome, who developed proteinuria. Electron microscopy revealed irregular thickening of the glomerular basement membrane with areas of rarefaction, giving rise to a pathognomonic moth-eaten appearance.

Focusing on the importance of exhibition industry, which had significant meanings with respect to marketing of participation companies as well as development of exhibition industry, this study analyzed the relationship between participation objectives and performance of exhibition. Furthermore, the determinants of exhibition choice and behavioral intention, associated with the two key factors above, were examined to suggest some ways to improve the competitiveness of the domestic exhibition industry. The results of this study elicited some implications. First, most companies, which participated in exhibition, established objectives and measured performance, by documentation before and after the exhibition. Second, there were significant relationship between participation objectives and determinants of exhibition choice, and third, participation performance of exhibition and behavioral intention also had positive correlation.
