The purpose of this study is to analyze the characteristics of the media contained in textbooks for students with disabilities based on the information processing model, and to find ways to utilize library materials for class improvement for them. To this end, the media included in the in-depth learning activities of the Korean language textbooks of the 2015 revised special education basic curriculum were analyzed. As a result of the analysis, it was found that students with disabilities received information mainly through vision, process information through understanding, and use language intelligence to produce results. Specifically, they accepts learning contents through illustrations and texts, processes the contents based on understanding such as reasoning and explanation, and then uses linguistic intelligence such as writing and speaking to produce results. Based on the results of this analysis, a practical method to utilize library materials in the Korean language class of students with disabilities was proposed as follows. Developing a variety of input mediums based on reading stages and collection mapping for students with disabilities. Providing book materials through reading and listening. Teaching appropriate methodological knowledge to self-directly solve advanced learning activities. In addition, developing types of writing and writing strategies that can help various production activities.

Speaker verification is becoming popular as a method of non-face-to-face identity authentication. It involves determining whether two voice data belong to the same speaker. In cases where the criminal's voice remains at the crime scene, it is vital to establish a speaker verification system that can accurately compare the two voice evidence. In this study, to achieve this, a new speaker verification system was built using a deep learning model for Korean language. High-dimensional voice data with a high variability like background noise made it necessary to use deep learning-based methods for speaker matching. To construct the matching algorithm, the ECAPA-TDNN model, known as the most famous deep learning system for speaker verification, was selected. A large dataset of the voice data, Voxceleb, collected from people of various nationalities without Korean. To study the appropriate form of datasets necessary for learning the Korean language, experiments were carried out to find out how Korean voice data affects the matching performance. The results showed that when comparing models learned only with Voxceleb and models learned with datasets combining Voxceleb and Korean datasets to maximize language and speaker diversity, the performance of learning data, including Korean, is improved for all test sets.

This study presents a multilingual integrated ontological approach that enables linking classification systems. thesauri. and terminology databases in science and technology for more effective indexing and information retrieval online. In this integrated system, we designed a thesaurus model with concept as a unit and designated essential data elements for a terminology database on the basis of ISO 12620 standard. The classification system for science and technology adopted in this study provides subject access channels from other existing classification systems through its mapping table. A prototype system was implemented with the field of nuclear energy as an application area.

In this study, diagnosis of the problem of self-directed learning for the improvement of the language, reasoning n eeded for NCOs typical for students currently enrolled as a cadet NCOs and suggested some lessons to improve this model. Proposed presentation, the three curriculum of presentation and discussion related to the configuration intervie w, self-directed learning was to be his students. In one of the ways to solve the problems experienced in a self-pac ed learning learner was used in this process is often the scaffolding system, is shown that can lead to improved abil ity to apply the result of expression of the three class model.

The purpose of this study is to determine factors affecting text difficulty and to model objective formulas which measure readability scores. Some readability-related factors such as total number of letters, total number of syllables, total number of unique syllables, total number of sentences and total number of paragraphs were found through correlation analysis. Some regression equations with these factors as their variables were produced through regression analysis. A model estimating readability score from total number of unique syllables was a good formula, while a model with two factors, total number of unique syllables and new syllable occurrence ratio, was a better enhanced one. The readability score represents detailed level so we can recommend students read texts corresponding to their reading levels.

In this paper, project based learning model using on-line thinking tool was designed and implemented, and the model is reflected in the instructional design on the IT ethics part included in 'General Computer' subject. This instructional design was applied to the class of the technical high school students. In-depth interview on the consciousness of IT ethics reveals that the positive changes occur in the consciousness of IT ethics, especially netiquette, Internet communications languages, copyright, and so on. Also, the result of the quantitative researches represents that a proposed model have a positive effect on academic self-efficacy of the technical high school students. These results show that the proposed model is able to apply to IT ethics education in the technical high school.

Illegal waste dumping is one of the major problems that the government agency monitoring water quality has to face. Recently government agency installed COD (chemical oxygen demand) auto-monitering machines in river. In this article we provide an outlier detection algorithm using R based on the time series intervention model that detects some outlier values among those COD time series values generated from an auto-monitering machine. Through this algorithm using R, we can achieve an automatic algorithm that does not need manual intervention in each step, and that can further be used in simulation study.

A variety of BPM (Business Process Management) standards to achieve interoperability among heterogeneous systems have been released. Areas of BPM standards include business process modeling, process execution and management, and monitoring and controlling. The purpose of this research is to develop an adoption strategy and guideline for implementing BPM standards. We suggest a strategy for implementing BPMN (Business Process Modeling Notation), BPEL (Business Process Execution Language), and BPQL (Business Process Query Language) and provide a specific implementation guideline for developing BPM solutions using each standard. We expect that BPM vendors can establish their own strategy for adopting BPM standards and implement BPM solutions efficiently and effectively with the help of the strategy and guideline described in this paper.

This paper extends TTCN, a conformance test notation, using object oriented concepts including object, class and inheritance. In distributed system environments, since test systems that should test the implementations for application protocols whether they conform to the standard protocol include protocol test behaviours executed in parallel, the converntional TTCN can't describe whole thest suites explicitly. ISO is working the extension of TTCN including parallel notations, but concurrently if TTCN could be applied by the object model that regards a parallel test component as a object, we would gain the advantages of reliability and software reusability, and make TTCN a test language.

In this thesis, we propose an Intelligent Agent based on CORBA technology which can exchange and share data under distributed computing environment using Agent Communication Language(ACL), Recently, due to the rapid development of network technology, the need for the database management appeared. So representative standard, CORBA have been applied and used under distributed environment. Agent applications are being developed for various fields such as electronic commerce, user interface, information retrieval. When a user searches goods, he navigates several servers on different platform until he finds desired goods. The Intelligent Agent presented in this thesis, does these tedious navigations on behalf of the user through communication between different platform.
