The purpose of this study was to examine the effects of group music therapy involving the creation of a musical play on the self-esteem, self-expression, and social skills of children. The participants were 14 first through third graders and 14 fourth through sixth graders from a children's center. Half of the children from each grade band (Grades 1-3 and 4-6) were assigned to the experimental group and the other half to the control group, for a total of 14 children in each group. The experimental group who participated in music therapy sessions focused on creating a musical play. The experimental group selected themes, made a script, composed song lyrics and music, and performed the completed musical play. The Self-Esteem Scale, Self-Expression Scale, and Social Skills Rating System (SSRS) were administered before and after the intervention. The experimental group exhibited significantly higher scores than the control group on all of the scales except subscales of the Self-Expression scale and the SSRS. The results of this study suggest that group music therapy can facilitate children's engagement in group work and that playing an important role in the group can positively impact their perceptions of themselves.

The purpose of this study was to investigate targets to use measurement tools to communicate developed in Korea and factors consisting of questions, to examine how measurement tools to communicate applied for AAC subjects were. In the case of measuring language and communication skills targeting people with disabilities, aphasia was out of common, in the case of applying to different types of failures, it showed rare. While factors consisting of questions on measurement tools to communicate had many factors on communication limitations and many factors on impairments in body functions that limit communication, they didn't have a lot of factors on restrictions in participation caused by communication limitations and lots of environmental factors that serve as barriers or facilitators for communication. AAC intervention was applied in the order of physical disabilities, autistic disorder, mental retardation, developmental disabilities, communication disorders, although "PPVT-R", "REVT" were widely used as measurement tools to communicate used in AAC intervention experiment, there were much more cases of relying on observation than standardized tools. Based on the results, we discussed that the need of evaluating to provide ACC application and individualized education(IEP)'s grounds and the research on evaluation criteria and measurement questions should be tried.

Objectives：Among the studies related to excessive computer use, the studies for elementary school students are relatively rare. Because children have relatively poor ability to recognize and express themselves, the carers' information is important to assess the children. This study attempted to investigate the relationship between children's computer use and sociopsychiatric characteristics on the basis of carers' reports. Methods：The subjects of this study were 287 5th- and 6th-grade students in the elementary school in Seoul. The student carers were asked to answer the questions for children's computer use, the computer addiction test modified from Young's parent-child internet addiction test, Korean Personality Inventory for Children(K-PIC). SPSS(version 10) was used to analyse the differnece of computer use between genders and the relation of the computer addiction test with K-PIC. Results：1) The score of computer addiction test was significantly higher in male children than in female children and more male children compared to female children were distributed in the excessive user group. 2) The score of computer addiction test correlated with the scores of most clinical scales of K-PIC and the average scores of most clinical scale were significantly higher in the excessive user group than in the general user group. 3) More children with score above 65 in HPR, DLQ, FAM scale were distributed in excessive user group than in general user group. Conclusion：The 5th- and 6th-grade elementary school students with excessive computer use were found to show more sociopsychiatric problems. With these finding we suggest that social and clinical attention to the children who use computer excessively shoud be required.

This paper presents a fast multiple-image-based deblurring method that decreases the computation loads in the image deblurring, enhancing the sharpness of the textures or edges of the restored images. First, two blurred images with some blurring artifacts and one noisy image including severe noises are consecutively captured under a relatively long and short exposures, respectively. To improve the processing speeds, the captured multiple images are downsampled at the ratio of two, and then a way of estimating the point spread function(PSF) based on the image or edge patches extracted from the whole images, is introduced. The method enables to effectively reduce the computation time taken in the PSF prediction. Next, the texture-enhanced image deblurring method of supplementing the ability of the texture representation degraded by the downsampling of the input images, is developed and then applied. Finally, to get the same image size as the original input images, an upsampling method of utilizing the sharp edges of the captured noisy image is applied. By using the proposed method, the processing times taken in the image deblurring, which is the main obstacle of its application to the digital cameras, can be shortened, while recovering the fine details of the textures or edge components.

IEEE 1451 standard defines an interface for network and transducer. In this paper, We propose an architectural model to configure data acquisition system and wireless smart sensor node based on IEEE 1451 standard. Proposed Network Capable Application Processor(NCAP) supports the task of data acquisition and communication for smart sensor node and network. The NCAP is able to reconfigure without interrupting the functionality of the wireless sensor node and receives the critical information of transducer using the DB. Smart sensor node is able to provide the basic information of sensor in digital format. This digital format is called Transducer Electronic Data Sheet(TEDS), is capable of plug-and-play capability of wireless sensor node and the NCAP. We simplify the format of TEDS and template to apply to wireless network environment. information of TEDS and template is transmitted using ad-hoc routing. This study system uses body temperature sensor and ECG(Electrocardiogram) sensor to provide the medical information service. The format of template is selected by data sheet of the sensor and reconfigured to accurately describe the property of the sensor. DB of NCAP is possible to register new template and information of the property as developing new sensor.

UN, OECD, ITU and other international organizations regularly announce ISI (Information Society Index) to utilize in establishing and evaluating information policies. ISI is utilized as important data for countries to evaluate their information policy performance and select future projects. As the advancement of information systems, the importance of information security has been emerged. Accordingly, NISI (National Information Security Index) has been required. NISI number is the most clearly figure to express the characteristics of a particular group's information security. It can be utilized in determining information security policies. Currently, questionnaire method has been used to calculate NISI number. But there is an absolute lack of statistical data, and the reliability of surveyed statistical data is problematic. The objective of this paper is to show how to collect precise micro data of each company's information security index numbers, and to develop an OLAP database system which calculating NISI numbers by using those micro data. In this process of the survey, we presented the technique to collect the data more systematically, and to analyze the data without using questionnaire method. OLAP architecture performs only well on the facts that are summarizable along each dimension, where all hierarchy schemas are distributive. Therefore we transformed the non-distributive hierarchy schema into the distributive hierarchy schema to implement OLAP database system. It is thought that this approach will be useful one from an implementation and schema design point of view.

This article addresses the 2nd Korean consensus conference on cloning that was held by the Korean National commission for UNESCO in 1999. Though previous perspectives recognized the conference as a new citizen's participatory institution. they do not consider that it contains the ideal of deliberative democracy. This article notes that the citizens participated directly and handled the important social agenda through debate in the consensus conference. The consensus conference is another democratic form derived from preference aggregating democracy in the sense that it basically depends on public judgement of the citizens. This consensus conference has the historical meaning because it is in fact the first experiment of deliberative democracy in Korea. 1) We examine the theoretical foundations of consensus conference. They are social constructionism of science, the tradition of societal debate, and deliberative democracy. 2) We explore what deliberative democracy is. It is different from aggregating preference democracy in the sense that it depends on public judgement rather than private preferences. 3) We investigate the features and meaning of deliberative democracy which has experiment on the conference. In the Consensus Conference it was observed that citizens changed their preferences and went forward to developing their view of community as a result of the process of deliberation. It can be said to confirm the significance of deliberative democracy. However, it is simultaneously an opportunity to clarify some problems of deliberative democracy. First of all, it shows that there were hierarchies within the citizens' panel as well as between the citizens' and the specialists' panels. Secondly, there are difficulties in expressing the value of life in argument or discourse. Also, we need the institutional efforts concerning future generations and nonhuman beings in the respect that cloning relates to them.

The purpose of study was to investigate practicing elementary teachers' pedagogical content knowledge and the significant predictors of their pedagogical content knowledge in science teaching. The PCK instrument was used to measure elementary teachers' pedagogical content knowledge. It consists of 6 factors to measure teachers' pedagogical content knowledge of 1)instructional methods, 2)representations, 3)contents, 4)evaluations, 5)students, and 6)curriculum. A questionnaire that consists of 7 questions regarding the teachers' degree, their number of years of teaching their choice of teaching science, their personal science teaching efficacy, their science teaching outcome expectation, their science instructional methods, and their attitudes toward teaching science, was also used to identify the information as to significant predictors of teachers' pedagogical content knowledge. A sample of 332 practicing elementary teachers participated in this study. To determine statistically significant predictors, Pearson's correlation coefficient and multiple regression methods were used to analyze the results. The results showed that the significant predictors of practicing elementary teachers' pedagogical content knowledge were their number of years of teaching, their science instructional methods, their personal science teaching efficacy and their attitudes toward teaching science. Further research of how teachers develop and construct their pedagogical content knowledge is recommended especially through the use of varied research methodologies that include qualitative methods.

In concrete structural design provisons, there is a minimum allowable strain of steel to ensure a ductility of RC members and a c/d is limited for the same purpose in EC2. In general, a ductility capacity of RC members is evaluated by a displacement ductility which is a ratio of ultimate displacement to yield displacement, and it is necessary to calculate accurately a yield displacement and an ultimate displacement to evaluate a displacement ductility. But a displacement in members is affected by various member characteristics, so it is hard to calculate a displacement exactly. In this study, a displacement ductility is calculated by calculating a yield displacement and an ultimate displacement through a moment-curvature relationship. The main variables examined are concrete strength, yield strength, steel ratio, spacing of confinement, axial force ratio and concrete ultimate strain. As results, as a concrete strength is increased, a ductility displacement is increased. But as yield strength, steel ratio, spacing of confinement and axial force ratio are increased, a displacement ductility is decreased. And a displacement ductility is necessary to calculate a response modification factor (R) of columns for seismic design, so it is appeared that it is important to calculate a displacement ductility more accurately.

Advancements in digital technology have caused significant changes to the tradition of creative educational activities. Such an with digital technology is prone to an error where digital technology itself becomes the goal, ignoring educational efficacy grounded on improved user experience and immersion. Previously, picture book-making activities for children allow them to actively participate in the process of book-making, and is often employed to instill reading habits as well as nurture linguistic abilities. Aside from such picture book-making activities, diverse efforts are being made for innovation in educational pedagogy through digital technology. However, as the goal of children's picture book-making activities is realizing creative education through expressions in language and pictures, digital technology should be considered in the viewpoint of fusion, not as a simple replacement to the traditional tools employed in children's picture book-making activities. This study examines previous researches related to children's picture book-making activities to propose contents and methodology allowing effective immersion by fusing digital technology based on a physical environment, from the viewpoint of fusion and integration. Expect this study will become a fundamental data in visualizing a practical integration of digital technology in future creative education.
