The purpose of this study is to elucidate the emotion-understanding of Korean and thus to find out the importance of their way of self-expression by exploring the sentiment of Korean as regards their way of communications and self-expression therein. The method of this study is, being presumed the Cheong as the Korean's sentiment, to define the differences of concept between the Cheong traditionally used by them and the emotion employed in the psychology or the theory of consultation. And also, this study examines the aforementioned importance under the presumption that the Cheong in the Korean Culture makes it difficult that their emotion-understanding and self-expression to be perfect in their way of communication. In order to attain such purpose in this study, it investigates how they have seen the emotion-understanding and self-expression as to the way of communication throughout Carl G. Jung's psychology and T oegye Yi Hwang's theory of Human Mind and Nature respectively in the Occidental and Korean's Ideology. The most important thing, to be enlightened in this study, in the way of communication and self-expression are the emotion come from the big-Self(Self) in Carl G. Jung's psychology and that of the righteous sentiment from the human nature in T oegye Yi Hwang's theory of Human Mind and Nature. In conclusion, it reveals that our behavior, unvaryingly in the Orient and the Occident, is not the rational subject but the emotional one to be reacted only if our minds are attached mutually.

The widespread use of public networks, such as the Internet, for the exchange of sensitive data that need a severe security, like legally valid documents and business transactions. At the same time public-key certificates used for sensitive data interchange form the viewpoint of data integrity and authentication. But there are some weakness of data transfer capacity and security in public key infrastructure(PKI) environment. This paper use the RSA one-way accumulator to realize an efficient and dynamic authenticated dictionary, where untrusted directories provide cryptographically verifiable answers to membership queries on a set maintained by a trusted source.

We have developed Logic Design Training Kit for studying, actual training, designing of FPGA(Xillinx) or CPLD(ALTERA CPLD), the Digital Logic Device. This training kit has 12 matrix keys, RS232 port for serial communication and uses LED array. six FND(Dynamic), LCD as display part. That is standard specification for digital logic training kit. Special point of this kit is that we make two logic device trainig kit. This two logic device kit have more smaller and simple architecture because only uses one chip. That chip already includes a lot of functions that need for training kit, such as : complex logic circuit needed the two kind of logic devices, 16 way of system clock deviding function, serial communication interrupt....etc. We called that one chip is Center Bridge Chipset ; Xillinx FPGA Spartan2. User can select between using one device of FPGA or CPLD, or uses both them. Because of, Center Bridge Chipset has profitable architecture. it can work as Logic Device's networking with Master-Slave connection When using both logic devices.

The purpose of this study was to identify the relationship between mother's interactive responsiveness and infant's communication. The participants of this study were 64 pairs of infants aged 13 to 24 months and their mothers. The infants' communication and their mother's interactive responsiveness were observed during mother-infant's free play for 10 minutes. The mother's interactive responsiveness was analysed on the basis of turn-taking and gaze. The collected data were analyzed by one-way ANOVA and Pearson's correlation. It was found that the communication of infants aged 13 to 24 months developed rapidly with a certain tendency. Mothers' interactive responsiveness increased significantly with infants' age group. The relationship between mother's interactive responsiveness and infant's communication was significant.

Relay-assisted D2D communication extends the communication range of the D2D pairs and helps users to form D2D pairs effectively. However, due to the introduction of the multi-hop relaying, the D2D communication has to occupy extra transmission time, which may decrease the efficiency of the communication system. In this paper, we propose a scheme to make node receive D2D signal and BS signal at overlapping time to improve the spectrum efficiency according to ZigZag decoding and successive-interference-cancellation (SIC). In this way, more data can be delivered during the same duration, thus the network throughput can be further improved. Numerical results verify the performance improvement of the proposed scheme when compared with a baseline scheme. Moreover, we expand the proposed scheme from one-hop relay scenario to multi-hop relay scenario.

Secure multimedia multicast applications involve group communications where group membership requires secured dynamic key generation and updating operations. Such operations usually consume high computation time and therefore designing a key distribution protocol with reduced computation time is necessary for multicast applications. In this paper, we propose a new key distribution protocol that focuses on two aspects. The first one aims at the reduction of computation complexity by performing lesser numbers of multiplication operations using a ternary-tree approach during key updating. Moreover, it aims to optimize the number of multiplication operations by using the existing Karatsuba divide and conquer approach for fast multiplication. The second aspect aims at reducing the amount of information communicated to the group members during the update operations in the key content. The proposed algorithm has been evaluated based on computation and communication complexity and a comparative performance analysis of various key distribution protocols is provided. Moreover, it has been observed that the proposed algorithm reduces the computation and communication time significantly.

Software design patterns are reusable solutions to recurring problems that occur during software development. As programmers gain experience, they recognize the similarity of new problems to problems they have solved before. With even more experience, they recognize that solutions for similar problems follow recurring patterns. In this paper, as one of these reusable design-patterns, the Intermediator pattern for the efficient communication between business component is designed and implemented. Existent business components were way that follow Facade pattern. But Facade pattern is almost like the existing Interface pattern in that the communication of all the object outside the set is done by only one representative object, and this causes the traffic system to be overloaded. Therefore, the Intermediator pattern supplements the traffic overloads by improving the inefficient system of business components' communication through multi-interface, and make all communication behavior between objects done by Intermediator object which controls all actual behavior by way of Intermediator method implementation. Consequently, the Intermediator pattern is designed and implemented in this paper can bring down the level of coupling and raise the cohesion among objects, and refer to many of other object flexibly through several interfaces.
