The purpose of this study is to examine the effectiveness of the summer enrichment programs on Korean gifted students' science learning and creativity development. This program is organized by Purdue University Gilled Education Resource Institute (GERI) in U.S.A. Researchers conducted semi-structured interview with 6 Korean students and observed 12 Korean students and GERI teachers for teacher-student interaction and teaching strategies during science-related classes. From the results, GERI program developed from Purdue 3 stage enrichment model that emphasizes creative teaching strategies, group discussions, and individual research were effective to foster creative thinking of Korean gilled students. Despite their language barriers, Korean gilled students found GERI program experience fun, creative, easy, relaxing, and thereby satisfying for their psychological and academic needs. They expected the level of stimulation in GERI program to be higher and the class to be organized more systematically; however, they reported that the broad range of topics and diverse content of GERI classes helped them develop creativity more than Korean classes. These findings will make contribution to the improvement of the quality of gifted education curriculum and programming in Korea.

During the landscape design process, landscape architects produce various forms of drawings to visualize the future designed landscape. This work thoroughly examines the process of the utilization of James Corner's theory and practice of representation. Since the early 1990s, Corner has explored the characteristics and functions of landscape architectural drawing theoretically. Specifically, Corner argued that the use of visual representation makes it difficult to achieve the full embodiment of all of the multisensory characteristics of a landscape. Thus, he explored new drawing techniques that alternatively visualize the landscape and generate creative ideas(i.e., imagination of drawing), rather than a realistic illustration of not-yet-actualized landscapes(i.e., instrumentality of drawing). Corner's theory has evolved throughout the mid and late-1990s as applied to landscape practice. Corner embraced ecology and implemented the theory and practice of Landscape Urbanism, thereby once again emphasizing the instrumentality of drawing. Whereas the early theory mainly explored a perspective view using collage and montage, Corner later began to stress the importance of the instrumentality again. For example, Corner employed a mapping technique based on the instrumental map and that simultaneously creatively transforms it. Corner's theory and practice of representation fully explored the identity of landscape architectural drawings and reflected the interaction between theory and practice. Thus, his design and theoretical works continue to have significant influence on present landscape practice and theory.

Korean magnetoencephalography (MEG) system had been developed and installed to hospital. The Korean MEG system contains helmet-shaped arrays of 152 first-order double relaxation oscillation SQUID (DROS) sensor. As a clinical application we have measured and analyzed evoked responses in patients with functional brain disease by outer stimulation as follows; 1) auditory evoked field in patients with hemifacial spasm, 2) somatosensory evoked fields in patients with tumor. We confirm that neuromagnetic data by Korean MEG system can provide useful information for pre-surgical planning or functional brain research.

The hardware of the human body is given the life force by the sentence which is the physiological software that the program for cell activation by the electrical signal enters. The aim of this study is to create a better therapeutic environment for the human body that groaned with errors in the physiological and cognitive systems that are transmitted to neurons and neurons. The sentence program of the rated sijo, which is the software of the human body which has the function as a conductor to connect the emotions of joy, anger, sadness, and enthusiasm to the human mental system, can be connected to the neuron system of the human body, we tried to identify the principle of operating the motherboard of mind in humanities. Once these principles are identified, we can figure out how to minimize side effects and lead the body to a therapeutic program. The research found that there is a strong energy source that can operate the motherboard of the heart very quickly in the rated Sijo. This is because it is confirmed that new coding and re-coding of a number of rated sijo, or a new syllable of one syllable followed by the original syllable of the original syllable, are formed quickly and therapeutically.This has led to the possibility of literary therapy for mankind to upgrade the human psychic system in abundance through the function of the interaction between the sentence as a conductor that is synaptically connected to the human body and the mainboard of the mind attached to the human body without side effects in the future.

The purpose of this study is to develop and implement an alternative elementary science curriculum to enhance creative problem solving abilities. The curriculum consisting of three main elements was developed. The three elements are content knowledge, process knowledge and creative thinking skills. The curriculum was validated by more than 10 science educators, scientists, and curriculum specialists. In order to implement the curriculum, three lessons for 5th grade were developed and taught by a problem-based-learning(PBL) method in an experimental group during the second semester. For the comparison group the ordinary lesson based on the 6th national science curriculum was taught by the same science teacher during the same period. Performance assessment was developed and used for the pre and post test. Two-way ANOVA, and T-test were used to check whether there are any significant differences between the gains of scores(pre-post test) of the two groups. The results of the test showed that the experimental group increased significantly in the total creative thinking problem solving skills, but the comparision group did not.

Recently, as smartphones have rapidly come into wide use and various social networking services have grown, people perform a variety of interactions through the virtual and real world based on them. Usually, such services focus on easy formation of social links among users, supporting the exchange of simple messages among users on the networks. Twitter, one of such services used worldwide, supports short message service named Tweet and has over 200 million members signed up. n this paper, we propose techniques for supporting real-time group messaging based on the social network of Twitter and describe a smartphone group messaging system developed with the techniques. The system automatically forms a group that include a Twitter user and the followers of the user, supporting real-time group messaging among the group members. The developed system is composed of an XMPP protocol-based messaging server and smartphone client applications which perform real-time messaging based on the social network of Twitter. Twitter users can easily use the system utilizing Tweet messages, exchanging real-time messages with their followers within the groups instantly established on the XMPP server.

Prediction problems are widely used in medical domains. For example, computer aided diagnosis or prognosis is a key component in a CDSS (Clinical Decision Support System). SVMs with nonlinear kernels like RBF kernels, have shown superior accuracy in prediction problems. However, they are not preferred by physicians for medical prediction problems because nonlinear SVMs are difficult to visualize, thus it is hard to provide intuitive interpretation of prediction results to physicians. Nomogram was proposed to visualize SVM classification models. However, it cannot visualize nonlinear SVM models. Localized Radial Basis Function (LRBF) was proposed which shows comparable accuracy as the RBF kernel while the LRBF kernel is easier to interpret since it can be linearly decomposed. This paper presents a new tool named VRIFA, which integrates the nomogram and LRBF kernel to provide users with an interactive visualization of nonlinear SVM models, VRIFA visualizes the internal structure of nonlinear SVM models showing the effect of each feature, the magnitude of the effect, and the change at the prediction output. VRIFA also performs nomogram-based feature selection while training a model in order to remove noise or redundant features and improve the prediction accuracy. The area under the ROC curve (AUC) can be used to evaluate the prediction result when the data set is highly imbalanced. The tool can be used by biomedical researchers for computer-aided diagnosis and risk factor analysis for diseases.

The estrogen receptor-related receptors (ERRs) are a group of nuclear receptor superfamily of transcription factors. ERRs and estrogen receptors (ERs) have overlapping affinities for coactivators and DNA binding sites, but differ markedly in ligand binding and activation. The three mammalian ERR genes have been implicated in diverse physiological processes ranging from placental development to maintenance of bone density, whereas the molecular diversity, function, and regulation of ERRs in non-mammalian species are not well understood. In the present study, to investigate the involvement of ERR in transcription and embryogenesis in marine invertebrates, a cDNA encoding ERR (SnERR) was cloned from the gonad in Strongylocentrotus nudus, by polymerase chain reaction (PCR). The amino acid sequence of SnERR showed high homology with that of S. purpuratus (91%). A phylogenetic tree clearly showed that SnERR is a member of the ERR family and clustered in echinodermata group as supported by a high bootstrap value. We examined gene expression of SnERR during embryonic development of S. nudus using real-time PCR. During the embryonic development, the mRNA of ERR was significantly high levels in early development stages (4~64 cell) and larval stages. The SnERR slightly activated transcription through the classical estrogen response elements (EREs) in the presence of genistein. In addition, peroxisome proliferator-activated receptor $\gamma$ coactivator (PGC)-$1\alpha$ knwon as a coactivator of ERR enhanced the snERR-mediated transactivation, suggesting that the PGC-$1\alpha$ is a coactivator of SnERR.

While the existing Web focuses on the interface with human users based on HTML, the next generation Web will focus on the interaction among software agents by using XML and XML-based standards and technologies. The inference engine, which will serve as brains of software agents in the next generation Web, should thoroughly understand the Semantic Web, the standard language of the next generation Web. As abasis for the service, the W3C (World Wide Web Consortium) has recommended SWRL (Semantic Web Rule Language) which had been made by compounding OWL (Web Ontology Language) and RuleML (Rule Markup Language). In this research, we develop a backward chaining inference engine SMART-B (SeMantic web Agent Reasoning Tools -Backward chaining inference engine), which uses SWRL and OWL to represent rules and facts respectively. We analyze the requirements for the SWRL-based backward chaining inference and design analgorithm for the backward chaining inference which reflects the traditional backward chaining inference algorithm and the requirements of the next generation Semantic Web. We also implement the backward chaining inference engine and the administrative tools for fact and rule bases into Java components to insure the independence and portability among different platforms under the environment of Ubiquitous Computing.
