The purpose of this study was to analyze the effects of parent-child communication, and the self-efficacy of middle school students on school adjustment. The data was collected from 285 middle school students living in Kwangju. For statistical analysis, Cronbach' $\alpha$, t-test, one-way ANOVA, Scheffe's multiple Comparison Analysis, LSD and hierarchical regression analysis were used. The results were summarized as follows : concerning connections between demographic variables and parent-child communication, the education of the father made the most significant difference, followed by living standard, free time for communication with the father, and free time for communication with the mother. The level of communication with parent made a significant difference to each sub-factor of school adjustment. As a result of making a hierarchical regression analysis to find out the relative impact of the demographic variables on school adjustment, self-efficacy was identified as the most important variable and predictor of school adjustment. The independent variables exercised a different influence on the sub-factors of school adjustment. These results indicated that adolescent's self-efficacy is the most important variable to improve the school adjustment of students.

The purpose of this study was to investigate the influences of adolescents' body image and communication with their parents on the alienation of male and female middle school students. The subjects were 253 middle school students. The data were analyzed with SPSS win 18.0 using Cronbach's ${\alpha}$, t-test, one-way ANOVA, Scheff$\acute{e}$ test and stepwise regression. The findings showed that problematic communication with the father was the strongest factor in explaining the alienation of male middle school students. The second strongest factor was the middles school student's open communication with the mother, and the third strongest factor was the middle school student's perception of physical health. Unlike male students, open communication with the father was the strongest factor in explaining the alienation of female middle school students. Problematic communication with the mother was the second strongest factor. Perception of physical appearance was the third strongest, and perception of physical health was the fourth strongest factor. Based on the results of the study, implications were discussed in terms of the alienation of male and female middle school students.

Purpose: This study investigated the practices of preventing infectious diseases by daycare center teachers. The focus was on the mediating effects of self-efficacy in the relationship between communication skills and practices of preventing infectious diseases. Methods: This study used a descriptive correlational design. The participants were 164 daycare center teachers. Hierarchical regression was used to test the mediating effect of self-efficacy in the relationship between communication skills and practices of preventing infectious diseases. Data were analyzed using the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and hierarchical regression. The mediation effect was analyzed using an SPSS Macro program, PROCESS. Results: Significant relationships were found between communication skills and practices of preventing infectious diseases (β=.19, p<.001), self-efficacy and practices of preventing infectious diseases (β=.59, p<.001), and communication skills and self-efficacy (β=.27, p<.001). Self-efficacy had a significant mediating effect (β=.17, 95% confidence interval=0.07~0.29) on practices of preventing infectious diseases. Conclusion: In order to improve practices of preventing infectious diseases among daycare teachers, it is necessary to develop and apply interventions and methods that can increase effective communication skills and self-efficacy.

The communication method between human and robot is one of the important parts for a human-robot interaction. And speech is easy and intuitive communication method for human-being. By using speech as a communication method for robot, we can use robot as familiar way. In this paper, we developed TTS for human-robot interaction. Synthesis algorithms were modified for an efficient utilization of restricted resource in robot. And synthesis database were reconstructed for an efficiency. As a result, we could reduce the computation time with slight degradation of the speech quality.

타이포그래피는 형태와 의미라고 하는 양면을 가지고 있다. 즉, 읽기(reading)와 보기(seeing)를 모두 요구하는 요소들의 집합체인데 형태로서 나타내는 의미도 물론 중요하지만 정확한 의사전달을 위 하여는 수용자 측면에서 야기 될 수 있는 다양한 의미를 추정하여 그 의미를 표현해야 한다. 이러한 사고를 바탕으로 탄생한 ' 담론으로서의 타이포그래피' 는 디자이너 입장에서는 일방적인 커뮤니케이션이 아닌 대화 형식의 커뮤니케이션을 위한 새로운 스타일이다. 의미는 한 곳에 정체되어 있는 것이 아니라 수용자에 따라 무한한 가능성이 열려 있기 때문에 이러한 표현 방법의 의의는 매우 크다. 따라서 이를 실제 강의에 적용, 그 가능성을 확인하였다.

One objective in developing the next generation of wireless communication systems is to increase data rates and reliability. A promising way to achieve this is to combine multiple-input and multiple-output signal processing with a space-time coding scheme, which offers higher coding and diversity gains and improves the spectrum efficiency and reliability of a wireless communication system. It is noted, however, that time delay differences and phase differences among different channels increase symbol interference and degrade system performance. In this letter, we investigate phase differences and their effects on multiple-input and multiple-output systems, and propose a compensation algorithm for the Rayleigh fading model to minimize their effects.

In recent years, the utilization of the WSN have been rapid. Energy consumption of these networks must be as low as possible. LEACH algorithm is one of the clustering technique. We modify the traditional LEACH algorithm in such way that it will be capable to self-organize large number of nodes and for saving communication resources such as processing time and initiation time. The efficiency of the network highly depends on how the algorithm divides cluster area and selects cluster head. The proposed algorithm can be evaluated through the extensive simulation the result we obtained shows that the life time of a network is increased when energy load is distributed equally among the sensor.

In this paper, the author proposes an efficient group key agreement scheme in a mobile environment where group members frequently join and leave. This protocol consists of basic protocols and general ones and is expected to be suitable for communications between a mobile device with limited computing capability and a key distributing center (or base station) with sufficient computing capability. Compared with other schemes, the performance of the proposed protocol is a bit more efficient in the aspects of the overall cost for both communication and computation where the computational efficiency of the scheme is achieved by using exclusive or operations and a one-way hash function. Also, in the aspect of security, it guarantees both forward and backward secrecy based on the computational Diffie-Hellman (CDH) assumption so that secure group communication can be made possible. Furthermore, the author proves its security against a passive adversary in the random oracle model.
