The purposes of this study were to explore what components of science communication and its level are contained in text panels of exhibitions in natural history museums and to propose its development direction of exhibition education in Korea. First, to find out the component and level of science communication contained in exhibition panels, the researcher team developed the analyzing tool which was called SEPAT (Science Exhibition Panel Analyzing Tool), then employed them to profile the component and level of science communication. Second, the researchers introduced the exemplary designed media of exhibitions to demonstrate how much science communication could be enhanced. The results were made as follows. First, the components of science communication was considerably weighted toward to 'concept' one. There were also a few 'awareness' and 'engagement', both of which were under 5% in each zone of exhibition and there was not 'NOSI' or 'opinion' embedded in the analyzed exhibitions. Second, the various type of designing exhibitions were found to promote or enhance the restrictedly represented components of science communication. It is suggestable for exhibitions to be designed through various type of 'media' to enhance science communication. Visitors are required to experience rich science communication to meet their educational needs, and exhibition developers in natural history museums and other museums are recommended to be professional in containing all components of science communication through various type of designing exhibitions.

This study investigates the effects of parent-adolescent communication, adolescent self-esteem, and strategies in peer conflict situations on the satisfaction of adolescents with their peer relationships. The subjects included students attending a girls' and a boys' middle school in Gongju City. Random sampling was used to pick a class from each of the three grades in the schools. 233 students, who's both parents were living, were used in the final analysis in an effort to examine the impacts of student communication with parents on student satisfaction with their friends. The findings were as follows: the subjects most often used the yielding type of conflict-resolving strategy, followed by the cooperating, compromising, dominating, and avoiding strategy-type. The girls showed a higher level of parent-child communication than the boys. Girls had high self-esteem and mostly adopted the cooperating type of conflict-resolving strategies, followed by the yielding, compromising, dominating and avoiding strategy-type. The boys mostly employed the yielding strategy type followed by the cooperating, compromising, dominating, and avoiding strategy-types. The results indicate that the satisfaction level with friends was high among those who used the avoiding strategy-type less and yielding strategy-type more. Girls were found to have high self-esteem and engaged in communication with their parents. The compromising, cooperating, and dominating types of conflict-resolving strategies did not exercise significant influences on their satisfaction with friends.

Finger vein recognition, which is a promising biometric method for identity authentication, has attracted significant attention. Considerable research focuses on transmission-type finger vein recognition, but this type of authentication is difficult to implement in mobile consumer devices. Therefore, reflection-type finger vein recognition should be developed. In the reflection-type vein recognition field, the majority of researchers concentrate on palm and palm dorsa patterns, and only a few pay attention to reflection-type finger vein recognition. Thus, this paper presents reflection-type finger vein recognition for biometric application that can be integrated into mobile consumer devices. A database is built to test the proposed algorithm. A novel method of region-of-interest localization for a finger vein image is introduced, and a scheme for effectively extracting finger vein features is proposed. Experiments demonstrate the feasibility of reflection-type finger vein recognition.

Due to the increase in the data traffic for the aeronautical communications, LDACS has been proposed to support the data link in the continental domain. LDACS is defined in two standards of LDACS type-1 and LDACS type-2, which are going to be selected through the intensive comparison. In this paper, we analyzed two types of standards and evaluated their performance for various channel models. Simulation results show that both LDACS type-1 and LDACS type-2 have a good performance in the en-route channel model, while they have a poor performance in the airport channel model. In the comparison results for LDACS type-1 and LDACS type-2, LDACS type-1 shows the better performance of 1dB than LDACS type-2 owing to the stronger channel coding technique.

BCH code is one of the most widely used error correcting code for the detection and correction of random errors in the modern digital communication systems. The conventional BCH encoder that is operated in bit-serial manner cannot adequate with the recent high speed appliances. Therefore, parallel encoding algorithms are always a necessity. In this paper, we introduced a new systolic array type BCH parallel encoder. To study the area and speed, several parallel factors of the systolic array encoder is compared. Furthermore, to prove the efficiency of the proposed algorithm using tree-type structure, the throughput and the area overhead was compared with its counterparts also. The proposed BCH encoder has a great flexibility in parallelization and the speed was increased by 40% than the original one. The results were implemented on synthesis and simulation on FPGA using VHDL.
