The present study conducted in two parts toward employees in government office and state-owned companies, and financial companies. First, main impacts were demonstrated in the links between superior communication ability (SCA) and outcome variables (self-efficacy, and learning goal orientation). Second, mediating effects of self-efficacy and LGO were investigated in the relation SCA-Innovative behavior. The data which applied in analysis was collected from 318 employees who work at government office and state-owned companies, and financial companies in Jeju island. The results were as follows. First, SCA were positively associated with self-efficacy and LGO. Second, self-efficacy and LGO were fully mediated both relationships between SCA and innovative behavior. Findings were as follows. SCA is an important factor on self-efficacy and LGO. Such the results have meaningful implications in the research area of communication. The importance of self-efficacy and LGO were demonstrated when considering the both variable in the relations SCA-innovative behavior.

In this paper, measurement techniques of absorbing ability for a RAM were studied for RCS Reduction needed for materializing ADD's RF stealth. As for the measurement techniques of absorbing ability, the theories of the free space method, similar to real radar system, and transmission line method, suitable for lab scale, were established. And we made real RAM samples, measured absorbing ability according to each, and compared the results. After comparison, electromagnetic(EM) wave absorbing ability was measured to be somewhat superior in free space method and overall uniform pattern was observed. Therefore, by applying measurement techniques by stage and by frequency we could develop RAM in a more efficient way.

The purpose of this study explains how service characteristics such as service competence, service customization, interpersonal communication and image affect service trust and affective commitments and how service trust, affective commitment play a role in affecting risk-taking and service loyalty in specialty hospital. and then confirm the mediating role of relationship quality components such as service trust and affective commitment in the above path relation. For this purpose, the research hypothesis was verified by structural equation model analysis(SEM) using SPSS 21.0 and AMOS 20.0 statistical package. The results of the study are as follows. First, interpersonal communication influenced service trust, image influenced affective commitment, service ability influenced service trust and emotional commitment, while service customization did not affect any factor. Second, service trust and affective commitment did not effect each other. Third, service trust and affective commitment were more powerful in risk-taking than the influence on service loyalty. Fourth, Risk takings affected service loyalty. Therefore, marketers of special hospitals not only medical services by providing medical service with superior service ability, but also by always strengthening interpersonal communication at the time of providing services. This will enable consumers to overcome the avoidance in the service decision process and implement a specific service marketing strategy that can continuously use the hospital service.

Polarity correlation is a simplified version of the usual, having a possibility of real-time processing without any reduction of precision. In this paper, its applicability in deterministic signals is first explored generally, by theoretical or numerical analysis of four kinds of the typical signals. Then, based on the results, its two applications are proposed, that are detection and demodulation of FSK signals in digital communication, and time delay estimasion in ultrasonic A-mode measurement. The effectiveness of the proposed applications is confirmed by its superior implementation ability and the results of numerical experiments under practical circumstances.

In this paper, we introduce an escalator (ESC) algorithm based on the least squares (LS) criterion. The proposed algorithm is relatively insensitive to the eigenvalue spread ratio (ESR) of an input signal and has a faster convergence speed than the conventional ESC algorithms. This algorithm exploits the fast adaptation ability of least squares methods and the orthogonalization property of the ESC structure. From the simulation results, the proposed algorithm shows superior convergence performance.

In this paper we introduce a new escalator(ESC) structure-based adaptation algorithm. The proposed algorithm is independent of eigenvalues spread ratio(ESR) of channel and has faster convergence speed than that of the conventional ESC algorithms. This algorithm combines the fast adaptation ability of least square methods and the orthogonalization property of the ESC structure. From the simulation results the proposed algorithm shows superior convergence speed and no slowing down of convergence speed when we increase the ESR of the channel.

Recently, according to the rapid development of internet and communication technologies, a lot of works based on network techniques have been developed. In relation to this trend, the agent systems that had been studied in the early AI have been being studied greatly in association with the network techniques. This paper present a design model of a secretary agent system in which each secretary agent can manage the schedules of her/his superior, and the descriptions about the implementation of the secretary agent system. In the presented secretary agent system, a database system and a knowledge-based systems are included and cooperated with each secretary agent to provide the ability of manipulating lots of schedule data and making decisions on them. This paper also shows that the presented secretary agent system can behavior like a real secretary through the various superior-secretary-meeting-requester interactions, which is different from the roup scheduling programs or personal scheduling programs.

Expansion of network environment and multimedia demand universality of application service as HDTV, etc. During these processes, it is essential to process multimedia in real time in the wireless communication system based on mobile phone network and in the wire communication system due to fiber cable and xDSL. So, in this Paper the optimal memory allocation algorithm combines the merit of huffman encoding which is superior in simultaneous decoding ability and lempel-ziv that is distinguished in execution of compress is proposed to improve the channel transmission rate and processing speed in the compressing procedure and is verified in the entropy encoder of HDTV. Because the entropy encoder system using proposed optimal memory allocation algorithm has memory saturation prevention we confirms that the compressing ratio for moving pictures is superior than Huffman encoding and LZW.

Molecular modeling was performed to comprehend the chiral recognition of ${\alpha}$-methoxy-${\alpha}$-trifluoromethylphenylacetic acid (MTPA) enantiomers by cyclomaltoheptaose (${\beta}$-cyclodextrin,${\beta}$-CD) and 6-amino-6-deoxy-cyclomaltoheptaose (am-${\beta}$-CD). Monte Carlo (MC) docking coupled to constant temperature molecular dynamics (MD) simulations was applied to the investigation for the ${\alpha}$-methoxy-${\alpha}$-trifluoromethylphenylacetic acid complexation with two different CDs in terms of the relative distribution of the interaction energies. The calculated results are finely correlated with the experimental observations in chiral recognition thermodynamics. Am-${\beta}$-CD as a host showed the superior enantio-discrimination ability to the native ${\beta}$-CD where the amino group of am-${\beta}$-CD was critically involved in enhancing the ability of chiral discrimination via the Coulombic interaction with MTPA.

The authors investigated the artistic characteristics of autistic savant artists, hypotheses on the proximate and ultimate causes of their emergence, recent psychological and other studies about them, and psychological and neuroaesthetic studies about non-savant autistic individuals. The artistic features of autistic savant artists were significantly similar to those of outsider artists. Furthermore, the authors investigated the explanatory power of the paradoxical functional facilitation theory, the superior visual perception hypothesis, the "Hmmmmm" hypothesis, and the Neanderthal theory of autism regarding the emergence of autistic savant artists. In addition, we investigated whether an increase in savant characteristics was related to a decrease in the ability for social communication. The authors suggested that in studies on the aesthetic experience of non-savant autistic individuals, their aesthetic experience ability is never lower than that of neurotypical individuals and that some non-savant autistic individuals may potentially have artistic talent. Finally, the authors reviewed the effectiveness of the "autism savant spectrum syndromic disorder" proposed by some researchers. More scientific and systematic studies on autistic savant artists from a multidisciplinary perspective are warranted.
