Patients of dyslexia have an reading disorder marked by the occurrence of semantic errors. Because there is little understanding of dyslexia in korea, we use a translation version of foreign tester for testing the patients of dyslexia. However, the foreign testers is not suitable for testing the korean patients, because language is sensitive to national culture and trait. In this paper, we propose a model of tester for dyslexia Which is used for classification and analysis of korean patients. In addition, we show some characteristics of the implemented tester by a performance study.

Nucleation of a crack is readily defected by acoustic emission (AE) method. One powerful technique for AE waveform analysis has been developed as SiGMh (Simplified Greens functions for Moment tensor Analysis), as crack kinematics of locations, types and orientations are quantitatively determined. Because these kinematical outcomes are obtained as three-dimensional (3-D) locations and vectors, 3-D visualization is definitely desirable. To this end, the visualization system has been developed by using VRML (Virtual Reality Modeling Language). As an application, failure protest of a reinforced concrete beam is discussed.

Autism spectrum disorder (ASD) is diagnosed by the clinical decision of a trained professional based on the Diagnostic and Statistical Manual for Mental Disorders, Fifth Edition or International Classification of Diseases 11th Revision diagnostic criteria. To obtain information for diagnostic formulation, professionals should explore detailed developmental history, and can use structured or semi-structured assessment tools to observe interaction between the child and parents or strangers. Diagnostic assessment should include a profile of the strength and weaknesses of the individual and should be conducted using an optimal approach by a multidisciplinary team with appropriate techniques and experience. Assessment of language, cognitive, neuropsychological, and adaptive functioning should be conducted in ASD individuals prior to establishing an individualized treatment plan. Genetic testing, brain magnetic resonance imaging or electroencephalogram testing can be considered for identification of underlying causes.

On the bases of the 5 principles and the 4 criteria for designing and developing of the listening and the reading test of National English Ability Test (NEAT), this study presents Item-Types Decision-Making Model as a blueprint for designing and constructing the two tests. It sets up the criteria for validating item types, designs a modular type of test specifications, constructs an item-types bank, and specifies a complementary type of test specifications of the two tests. To gather all these threads up, it constructs Item-Types Decision-Making Model which consists of such components as the item-type pool, the validity criteria and the procedures of testing item types, the item-types bank, the modular and the complementary type test specification. Thus, it shows how the Model works in developing and constructing the two level-differentiated listening and reading tests (the 2nd and the 3rd rank) of NEAT. Finally, it discusses some implications and applications of the Model to the two level-differentiated tests (the A and the B type) of 2014 CSAT (College Scholastic Ability Test) systems, National Assessment of Educational Achievement (NAEA), and classroom testing. In conclusion, Item-Types Decision-Making Model functions as a testing template in an item development system and as a matrix in an item-types bank system.

This paper proposed new approach for the information gifted discrimination test usign EPL. We tried to distinguish high level thinking in the information gifted through test of this study. We designed discrimination test by the features of EPL and developed testing item tool like single-sprit and multi-sprite. These items are divided into adding block, changing the block order, modifying value io block, and changing a block. We designed this testing tool that the elementary students can solve items without an experience on learning programming language. We expect the testing tool io proposed this study will help to discriminate the information gifted effectively.

In this paper, a new structure that can do fault detection and location of digial logic circuits more efficiently using current testing techniques is proposed. In the conventional method, observation point for steady state power supply current was only one, but in the proposed method more fault classes are divided for fault detection and location through the ovservation of steady state power supply current at two points. Also, it is shown that this structure can be easily applied in detection of stuck-open fault which is not easy to do testing with conventional current testing techniques. In the presented mehtod, an extra trasnistor is used, and current path is made compulsorily in the CMOS circuits in which no current path can be established in steady state, then it can be known that stuck-open tault is in the MOS transistor on the considering current path, if this path disappears due to stuck-open fault. The validity and the effectiveness is shwon, thorugh the SPICE simulation of circuits with fault and the current path search experiment using current path search program based on transistor short model wirtten in C language on SUN sparc workstation.

Many applications of DSMS(Data Stream Management System) require not only to process real-time stream data efficiently but also to provide high quality services such as data mining and data warehouse combining with DBMS(Database Management System) to users. In this paper we execute the performance benchmark of the combined system of DSMS and DBMS that is developed for high quality services. We use the stream data of network monitoring application system and combine the traditional representative DSMSs and DBMSs in a single system for the performance testing. We develop the total performance benchmark tool implementing JAVA language for the our testing. For our performance testing, we combine DSMS such as STREAM and Coral8 and DBMS such MySQL and Oracle10g respectively.

Packaging materials and articles that are used in food contact applications can transfer constituents in the foodstuffs. This kind of risk of possible health hazards to consumers has been generally recognized for a long time with the consequence of establishing corresponding food regulations in most developed countries. However, the language of these laws, their interpretation, and their level of enforcement vary from country to country. Accordingly, the actual migrating levels from packaging materials can be varied depending on the migration testing methods as prescribed in the national legislation in each countries. Therefore, there are needs of elimination of non-tariff trade barriers raised by sanitary and phytosanitary or technical measures under the Final Act of the UR Agreement. In this connection, the EU and USA are currently in an ongoing process of legislation harmonization to overcome potential barriers to free trade. In general, regulations governing component transfer in the USA are more complicated and comprehensive than similar regulations in Europe. In future, standard migration testing procedures for microwave heat susceptor materials and for the use of fatty food simulant should be established and also harmonized among countries. The objective of this investigation is to compare the current regulations for migration testing for plastic containers and packaging materials in USA, EU and Korea or Japan. For those regulations, Korean standards are required to be kept up with the international standards. By doing this, the related Korean regulation could be amended along with the worldwide progress for harmonization.

The design of safety computer system is described along with the case of software design and testing in the Core Protection Calculator System (CPCS). The application of computer system in safety system requires not only hardware qualification but thorough testing on software to verify its correctness and completeness. The testing on software for CPCS is performed by comparing the outputs of two versions of code. One is implemented in assembly language and the other is in Fortran. The testing is performed in sequencial and overlapping manner. Phase I test verifies that each software module is implemented correctly by executing every branch. Phase II test verifies that the integrated software is complete, meeting its requirements specification and also the integrated system meet its requirement and timing constraints. Through these testing, the Yonggwang Nuclear Power Plant Units (YGN) 3 and 4 CPCS software is verified to be correct and complete, and the integrated system is designed as in its requirements specification.
