Using a variety of data-mining methods on high-throughput cDNA microarray data, the level of gene expression in two different tissues can be compared, and DEG(Differentially Expressed Gene) genes in between normal cell and tumor cell can be detected. Diagnosis can be made with these genes, and also treatment strategy can be determined according to the cancer stages. Existing cancer classification methods using machine learning select the marker genes which are differential expressed in normal and tumor samples, and build a classifier using those marker genes. However, in addition to the differences in gene expression levels, the difference in gene-gene correlations between two conditions could be a good marker in disease diagnosis. In this study, we identify gene pairs with a big correlation difference in two sets of samples, build gene classification modules using these gene pairs. This cancer classification method using gene modules achieves higher accuracy than current methods. The implementing clinical kit can be considered since the number of genes in classification module is small. For future study, Authors plan to identify novel cancer-related genes with functionality analysis on the genes in a classification module through GO(Gene Ontology) enrichment validation, and to extend the classification module into gene regulatory networks.

This study observes information education of facilities for the disabled. A certain facility for the disabled was selected in Daejeon to compare the educational environment for visually disabled of regular school for visually disabled and facilities for the disabled, and then personnel current situation by age and form of the disabled, teacher current situation by age, computer possessing current situation, weekly education schedule for the disabled, and equipment possessing current situation for visually disabled were observed. As a result, expansion of Braille education was necessary for the Braille skilled, which is the basis of information education information to visually disabled is insufficient, and forming of learning environment was desperate since equipment necessary for computer education was absurdly lacking unlike regular schools. Also, only 10 out of 21 teachers(47%) majored in social welfare or special education, and none majored in computer. It is because support for employment of those who majored social welfare, special education, and computer is insufficient compared to treatment for teachers at general schools at the facility for the disabled since teacher employment regulation at the facility for the disabled is not set. It is studied that providing high-quality of education environment to the disabled was desperate through physical and social treatment that suits nurturing of the professionally knowledge personnel through expansion of equipments and constant education and training based on government support to promote information education of the facility for the disabled.

Purpose: This study reviewed the innovative educational strategies that have been implemented successfully in US baccalaureate nursing education programs to facilitate appropriate attitudes about caring for older adults. Methods: The data were collected through a search of PubMed and CINAHL using the key words, gerontological or geriatric, attitudes about aging or older people, baccalaureate or undergraduate nursing education or curriculum. Results: The successful strategies are categorized as follows: 1) a multidisciplinary approach integrating aging issues and gerontological contents into diverse nursing courses, 2) active participation of community-dwelling healthy older individuals as an educational mentor, 3) use of audiovisual materials to investigate the misconceptions and attitudes about aging, and 4) discussion through critical thinking and self-reflection toward aging. Implications: For the interdisciplinary approach within nursing courses, it is essential to derive the key contents for gerontological nursing applicable to integration into diverse nursing courses. In addition, it is necessary to provide administrative support for implementing innovative strategies and constructing consistent partnerships with the community for active participation of the elderly as a mentor. Lastly, recognizing the significance of educational strategies for enhancing desirable attitudes toward gerontological nursing and supporting the development of educational capability of a faculty are key issues.

Recently, due to the development of the Internet and electronic devices, there has been an enormous increase in the amount of available knowledge and information. As this growth has proceeded, studies on large-scale ontological reasoning have been actively carried out. In general, a machine learning program or knowledge engineer measures and provides a degree of confidence for each triple in a large ontology. Yet, the collected ontology data contains specific uncertainty and reasoning such data can cause vagueness in reasoning results. In order to solve the uncertainty issue, we propose an RDFS reasoning approach that utilizes confidence values indicating degrees of uncertainty in the collected data. Unlike conventional reasoning approaches that have not taken into account data uncertainty, by using the in-memory based cluster computing framework Spark, our approach computes confidence values in the data inferred through RDFS-based reasoning by applying methods for uncertainty estimating. As a result, the computed confidence values represent the uncertainty in the inferred data. To evaluate our approach, ontology reasoning was carried out over the LUBM standard benchmark data set with addition arbitrary confidence values to ontology triples. Experimental results indicated that the proposed system is capable of running over the largest data set LUBM3000 in 1179 seconds inferring 350K triples.

This study analyzed the influence of cultural empathy and analysis on the cultural sensitivity and understanding of multicultural education and the relationship between the attitudes and cultural empathy and understanding of multicultural education and the multicultural sensibility and attitudes of pre-service early childhood teachers. We conducted a survey on cultural sensitivity, multicultural education and understanding attitude among Early Childhood Education College and enrolled 165 infants with pre teachers in pre-service early childhood teachers who are able to sympathize with cultural areas of the Y. The data were subjected to Pearson correlation analysis with multiple regression analysis performed using the SPSS 21.0 program. From the data analysis, first, cultural empathy and multicultural sensitivity showed a significant positive correlation with understanding and attitudes of multicultural education pre-service early childhood teachers. Second, cultural empathy of the pre-service early childhood teachers was a significant variable for predicting the susceptibility multicultural, multicultural education and understanding attitude. Since cultural empathy can change according to various factors, future investigation of these factors is needed to increase the cultural sensitivity of pre-service early childhood teachers by conducting follow-up studies that apply these findings to educational programs. Cultural empathy shouldn't be limited to multicultural education or simply a means to access the field of experiencing the arts, but should be expanded to include research in teaching and learning on how cultural empathy can be applied to the overall educational curriculum.

SQL Injection attacks are the most widely used and also they are considered one of the oldest traditional hacking techniques. SQL Injection attacks are getting quite complicated and they perform a high portion among web hacking. The big data environments in the future will be widely used resulting in many devices and sensors will be connected to the internet and the amount of data that flows among devices will be highly increased. The scale of damage caused by SQL Injection attacks would be even greater in the future. Besides, creating security solutions against SQL Injection attacks are high costs and time-consuming. In order to prevent SQL Injection attacks, we have to operate quickly and accurately according to this data analysis techniques. We utilized data analytics and machine learning techniques to defend against SQL Injection attacks and analyzed the execution plan of the SQL command input if there are abnormal patterns through checking the web log files. Herein, we propose a way to distinguish between normal and abnormal SQL commands. We have analyzed the value entered by the user in real time using the automated SQL Injection attacks tools. We have proved that it is possible to ensure an effective defense through analyzing the execution plan of the SQL command.

An edutainment system aims to help learners to recognize problems effectively, grasp and classify important information needed to solve the problems and convey the contents of what they have learned. Edutainment contents can be usefully applied to education and training in the both scientific and industrial areas. Our present work proposes an edutainment system that can be applied to a drug discovery process including virtual screening by using intuitive multi-modal interfaces. In this system, a stereoscopic monitor is used to make three-dimensional (3D) macro-molecular images, with supporting multi-modal interfaces to manipulate 3D models of molecular structures effectively. In this paper, our system can easily solve a docking simulation function, which is one of important virtual drug screening methods, by applying gaming factors. The level-up concept is implemented to realize a bio-game approach, in which the gaming factor depends on number of objects and users. The quality of the proposed system is evaluated with performance comparison in terms of a finishing time of a drug docking process to screen new inhibitors against target proteins of human immunodeficiency virus (HIV) in an e-drug discovery process.
