Objectives : The aim of this study was to observe and analysis the effectiveness of clinical treatments on the growth of children treated with Korean herbal medicine (KHM). Methods : Forty-two children of growth retardation were evaluated from January 2007 to May 2008. All children were administered KHM with diet and exercise guidance. Height percentile and predictive height were calculated following the General Growth Statistics Result (2007), and compared those of pre-treatment with post-treatment. Results : Thirty-one of them were improved (73.8%) and eleven were not (26.2%). The mean growth rate was 7.2cm/yr for male and 6.8cm/yr for female. The mean growth percentile of male showed 7.6% improvement (p=0.003), female 4.4% respectively (p=0.036). The mean predictive height of male showed 2.2cm improvement (p=0.005), female 1.0cm respectively (p=0.007). Change of growth percentile and height were significantly higher on period of prepuberty, and in small children below 50% of height percentile. About inter-relations between growth improvement and compliance of diet, exercise or medication, meaningful statistics were shown in diet control than the others (p=0.077). Diet compliance was in close connection with exercise, but others were not shown close correlations. Conclusions : These results showed that KHM showed promising results on children growth and healthy diet would be an important factor for growth of children. And it was recommended that KHM should be applied on period of prepuberty and smaller than average height.

The first purpose of this paper is to disclose the reason why integrated teaching/learning between Information Literacy Subject(ILS) and the other school subjects is necessary in order to enhance students creativity. Postulated creativity is generated from integration of information, the author discusses about the function of human mind and brain by studying Schema theory of Jean Piaget and the human celebral cortex. The author then, discloses the function of human information process(thinking process) is an integrating process of information within the mind and brain. The fact that a thinking process is an integrating process of information implies the necessity of integrated teaching/learning between ILS and the other school subjects. The second purpose of this paper is to find out the urgent points to implement the integrated teaching/learning between ILS and the other subjects at present school situation. The findings from the survey shows that school libraians and teachers are primarily positive about the integrated teaching/learning in connection with enhancing students creativity. However, they are not familiar with about the integrated teaching/learning. Therefore, the writer draws following recommendations. The curriculum for school library media specialist to be at library school should include the rationale, contents, methods and effects of integrated teaching/learning and school library collections are ready to implement the integrated teaching/learning between ILS and the other school subjects.

This paper presents a new efficient and stable multilevel partitioning algorithm for VLSI circuit design. The performance of multilevel partitioning algorithms that are proposed to enhance the performance of previous iterative-improvement partitioning algorithms for large scale circuits, depend on choice of construction methods for partition hierarchy. As the most of previous multilevel partitioning algorithms forces experimental constraints on the process of hierarchy construction, the stability of their performances goes down. The lack of stability causes the large variation of partition results during multiple runs. In this paper, we minimize the use of experimental constraints and propose a new method for constructing partition hierarchy. The proposed method clusters the cells with the connection status of the circuit. After constructing the partition hierarchy, a partition improvement algorithm, HYIP$^{[11]}$ using hybrid bucket structure, unclusters the hierachy to get partition results. The experimental results on ACM/SIGDA benchmark circuits show improvement up to 10-40% in minimum outsize over the previous algorithm $^{[3] [4] [5] [8] [10]}$. Also our technique outperforms ML$^{[10]}$ represented multilevel partition method by about 5% and 20% for minimum and average custsize, respectively. In addition, the results of our algorithm with 10 runs are better than ML algorithm with 100 runs.

Art has evolved into remarkable changes in its art form maintaining a close link with the contemporary scientific technologies that gave birth to new tools of expression in each era. Animation is an art form in an inextricable connection with technological aspects because it was spawned by the technical background like movies. In this regard, animation is often viewed very strongly by technical advancements in terms of an aesthetic approach. John Whitney Sr., one of the pioneers in computer graphics arts, turned his attention to the new technology called computer graphics as a means to visualize images and movement. The advent of a new medium had a strong influence not only on tools and means for novel expression but also on the gradual shift in thinking about arts and even the audiences' taste. In the 1980s, animation was combined with computer technology and the rapid progress of computer graphic technology opened up the era of new visual aesthetics, Today, the development of digital technology presents a different dimension of realism, either advocating hyperrealism by digital actors or presenting new illusionism by classic cartoon characters emphasized in a distortion or metamorphosis from a real life in order to consolidate animation realism. Based on the two perspectives mentioned above, this study can identify methods of digital character appropriation focused on the works of the ACM SIGGRAPH Asia and find how the relationship between art and technology has changed the digital realism and evolved the digital character as the digital technology has developed.

The purpose of this study was to understand the parents' perceptions of the distance learning provided to students with disabilities and to explore the demands for educational support. A survey was conducted on a total of 2,392 parents of school-age children with disabilities. The survey questions were largely divided into the learning support to prevent educational gap, support for behavioral and psychological difficulties, and care support for educational welfare. As a result of the study, it was found that face-to-face education in schools was the most important to prevent the educational gap between students with disabilities, and counseling on distance learning methods and strategies suitable for the characteristics of the disabled in connection with the Special Education Support Center was the most necessary. As a learning support method for distance learning for students with disabilities, there was a high demand for individual learning support through preparatory special education teachers, and it was necessary to secure enough learning aids and assistive technology devices to be used appropriately when needed. In addition, psychological counseling and educational support for students with disabilities were requested, and there were demands for development of care programs suitable for the characteristics of the disabled and assignment of dedicated personnel. Based on the results of this study, this study suggested implications for students with disabilities to bridge the learning gap and provide educational support due to distance learning.

Objective: With the onset of stroke, white blood cells release several proinflammatory cytokines, including interleukin (IL)-6, IL-10, and tumor necrosis factor $(TNF)-{\alpha}$. It has been proven in previous studies that the release of these cytokines is related to the extent of damage to the brain and to overall prognosis. However, no studies have yet been performed to determine the connection with IL-6 and IL-10. Thus, this study is performed to see whether polymorphisms of IL-6, IL-10, and $TNF-{\alpha}$ genes that show increased serum concentration with the onset of stroke are related to stroke attack in Koreans. Methods : Peripheral blood samples derived from patients with stroke (n=100) and healthy controls (n=100) were taken under informed consent. In subjects with stroke, blood samples were obtained within 24 hours of stroke onset. Genomic DNA was isolated using the Wizard DNA Purification Kit (Promega, Madison, WI). Results : 1. Subjects with Heterozygote (GA) and Homozygote (AA) $TNF-{\alpha}$ gene types showed 2.433 and 20.457 times higher risks of being attacked by stroke, respectively, compared to subjects with wild type (GG) $TNF-{\alpha}$ gene type. The data was still statistically significant after adjusting for age, sex, history of smoking, and history of alcohol drinking. 2. Subjects with Homozygote (CC) IL-6 gene type showed 182.033 times higher risk of being attacked by stroke, compared to subjects with wild type (GG) IL-6 genes. This data was statistically insignificant (p=0.700). The data was still statistically insignificant after adjusting for age, sex, history of smoking, and history of alcohol drinking. 3. Subjects with Heterozygote (GA) and Homozygote (GG) IL-10 gene types showed 8.785 and 3.303 times higher risks of being attacked by stroke, respectively, compared to subjects with wild type (AA) IL-10 genes. The data was still statistically insignificant after adjusting for age, sex, history of smoking, and history of alcohol drinking. Conclusion : Our results suggest that the investigated $TNF-{\alpha}$ and IL-10 gene polymorphisms play an important role in stroke attack, but IL-6 gene polymorphism has not been found to associated with stroke.

Purpose : The simulator is used to determine patient field and ensure the treatment field, which encompasses the required anatomy during patient normal movement such as during breathing. The latest simulator provide real time display of still, flouroscopic and digitalized image, but conventional simulator is not yet. The purpose of this study is to introduce digital image capture system(DICS) using conventional simulator and clinical case using digital captured still and flouroscopic image. Methods and materials : We connect the video signal cable to the video terminal in the back up of simulator monitor, and connect the video jack to the A/D converter. After connection between the converter jack and computer, We can acquire still image and record flouroscopic image with operating image capture program. The data created with this system can be used in patient treatment, and modified for verification by using image processing software. (j.e. photoshop, paintshop) Result : DICS was able to establish easy and economical procedure. DCIS image was helpful for simulation. DICS imaging was powerful tool in the evaluation of the department specific patient positioning. Conclusion : Because the commercialized simulator based of digital capture is very expensive, it is not easily to establish DICS simulator in the most hospital. DICS using conventional simulator enable to utilize the practical use of image equal to high cost digitalized simulator and to research many clinical cases in case of using other software program.

As regulations of emissions from ships become more stringent, electric propulsion systems have been increasingly used to solve this problem in vessels ranging from large merchant ships to small and medium-sized ships. Methods for improving the efficiency of the electric propulsion system include the improvement of power sources; the use of a system linked to environmentally friendly power sources, such as batteries, fuel cells, and solar power; and the development of hardware and control methodology for rectifiers, power conversion devices, and propulsion motors. The method using a phase-shifting transformer with diodes has been widely used for rectification. Power semiconductor devices with grid connection to an environmentally friendly power source using DC distribution, a variable speed power source, and the application of small and medium-sized electric propulsion systems have been developed. Accordingly, the demand for active front-end (AFE) rectifiers is increasing. In this study, a method using a neural network rather than a conventional proportional-integral controller was proposed to control the AFE rectifier. Tested controller data were used to design a neural network controller trained through MATLAB/Simulink. The neural network controller was applied to a rectification system designed using PSIM software. The results indicated the effectiveness of improving the waveform and power factor DC output stage according to the load variation. The proposed system can be applied as a rectification system for small and medium-sized environmentally friendly ships.
