Established on February 1st, 2010, The ROKN maritime task flotilla has a goal to successfully cope with North Korea and other potential threats. Unlike precedents of its kind, The ROKN maritime task flotilla is expected to concentrate more an far-sea strategies than coastal strategies. In such circumstances however, the existing maritime logistics systems have limitations upon which to utterly support the operation conception of the ROKN maritime task flotilla seven. To ensure it's efficiency, transformation of the systems is prerequisite. The purpose of this study is to deduce an adequate maritime logistics system for the ROKN maritime task flotilla by evaluating the limitation of the current system and foreseeing its performance necessary abilities to operate in the future. In order to do this, the study presented problems and the direction of development on the structural and behavioral sides. Fist, regarding problems in the structure of maritime logistics system, the investigation pronounced the need of improvement in mobile logistics support ability and its speed. In addition, for the behavioral side, the need of improvement in logistics cooperation system and self-maintenance ability was affirmed. For the development of an adequate maritime logistics system, the study suggested the amelioration in the operation of an adequate mobile logistics support platform and the speed of the logistics using high-speed transportation such as planes for the structural side. Moreover, for the behavioral side, it recommended th enhancement of logistics cooperation system including the nations that already imported th weapon system, amelioration of self-maintenance ability, and necessity to operate mobile maintenance group.

In order to understand how various support programs affect the development of traditional performing arts, I used descriptive statistics and multivariate statistics analysis on 267 surveys. I estimated relationship between item-whole by calculating mean and standard deviation. This will help us comprehend effects of the variables. Cronbach alpha coefficient, a measure of internal consistency, exceeded 0.7, indicating that reliability is satisfactory. I have established one main hypothesis and four sub-hypothesis to identify the relationship between support programs and the performing arts more clearly. The result supports that the support programs do have effects on the performing arts. However, there are not enough researches done on this subject, and additional researches are needed in order to systemize relevant theories and the development of performing arts industry.

Recently, due to technical developments of various storage devices and networks, the amount of data increases rapidly. The large volume of data streams poses unique space and time constraints on the data mining process. The continuous characteristic of streaming data necessitates the use of algorithms that require only one scan over the stream for knowledge discovery. Most of the researches based on the support are concerned with the frequent itemsets, but ignore the infrequent itemsets even if it is crucial. In this paper, we propose an efficient method WSFI-Mine(Weighted Support Frequent Itemsets Mine) to mine all frequent itemsets by one scan from the data stream. This method can discover the closed frequent itemsets using DCT(Data Stream Closed Pattern Tree). We compare the performance of our algorithm with DSM-FI and THUI-Mine, under different minimum supports. As results show that WSFI-Mine not only run significant faster, but also consume less memory.

An authentication between a user's terminal and a Access Control Router (ACR) is preceded so that a user receives secure WiBro services. Otherwise they can be exposed from many attack risks. So the Telecommunications Technology Association (TTA) constituted a mechanism of the mutual authentication for WiBro service. In mechanism a user executes the mutual authentication between a Portable Equipment (PE) and the ACR by using Portable Internet Subscriber Identity Module (PISIM). But this standard needs many message to authenticate the ACR and the users cann't use wireless Internet service. Therefore in this paper we propose the key agreement protocol between the PSS and the ACR to authenticate the PSS to ACR. At this time Power Support Device (PSD) fer supporting the calculated quantity of the PSS is participated in the key agreement protocol. The ACR sends a generated key to Key Authentication Server (KAS) via secure IPsec tunnel and then it preserves the identity of the PSS and the value of key after it enciphered them. In conclusion we analyze the security and efficiency of the proposed protocol.
