The purpose of this study was to evaluate the contents of Korean-learning applications by comparing two teaching methods(Phonics Instruction/Whole Language Approach). For this purpose, a total of 51 Korean-learning applications were analysed. The instruments used in this study were developed based on Applications for preschoolers Evaluation Criteria and Vocabulary Game Applications for preschoolers Evaluation Criteria. The collected data were analyzed by using a t-test. The main results are as follows. First, 'Developmental appropriateness' had the highest scores whereas 'Amusement' had the lowest scores in general. Second, there was a significant difference in 'Interaction' by teaching method. Implications for the development of more systematic Korean-learning applications for preschoolers are discussed.

Currently, XML and its schema language have become the standard for data representation and information exchange format on the current web. Unfortunately, problems happen when integrating different data sources since XML mainly supports the document structure but lack consideration on sharing knowledge of data. Meanwhile, Semantic Web technologies, such as Web Ontology Language (OWL), can include the structure as well as the semantics of the data. Therefore, finding a way to integrate XML data as OWL ontology receives a high interest nowadays. In this paper we present a mapping notation to convert XML Schema to OWL domain knowledge and an effective method to transform XML instances into OWL individuals. While keeping the XML original structure, our work also adds more semantics for the XML document. Moreover, whole of the transformation processes are done automatically without any user interference. Further, our transforming approach provides the solution for duplicate element names in XML document which has not mentioned in the previous work. Our results in existing OWL syntaxes can be loaded immediately by OWL editors and Semantic Web applications.

The main objective of this research is to identify the evaluation criteria of the local governments' projects for the fisheries industry development (LGPFID) and to develop the evaluation software prototype applicable to LGPFID. This research does not try to develop the whole evaluation processes and programs for LGPFID, but just to outline the approach to managing LGPFID. The evaluation processes and programs developed in this study is based on the group decision support systems(GDSS), which is a collaborative, system-oriented, and objective system useful in evaluating LGPFID. Specifically the goals of the programs are to : (1) enhance the quality of evaluation process for LGPFID; (2) provide the local government decision makers' and interest groups' access to comprehensive evaluation information; (3) support private-public collaboration in government's decision making. We used analytic hierarchy process model as a group decision making model and programmed the application software prototype with Visual Basic language.

In modern systems technology, increasingly more systems are anticipated to operate in real-time environment. These systems are usually complex to implement since it is not easy to satisfy the real-time requirement for both hardware and software components simultaneously. In this paper, we first review an object-oriented development process that was proposed earlier for software-intensive real-time system using the Unified Modeling Language (UML). We then study how to improve the problems that the UML approach might have. Applying the systems engineering(SE) process yields useful results which include : 1) an improved requirements management over the whole system life-cycle ; 2) a detailed scenario on how to carry out the SE process ; and 3) a conversion process from the text-based requirements to the UML-based graphic ones.

This study suggested speech generation device(SGD) program to materialize the proper communication aids which address to language abilities by students with cerebral palsy in the stage of word recognition achievement. This SGD program aim at function of learning mediation and communication expression by synchronization not restrict aim of AAC aids' employment to the only function of communication expression. And this SGD was designed to evaluate language abilities of student with cerebral palsy through analysis of the date offered at this program, and then might utilize to set learning goals and objects, modify teaching contents. This SGD program have a meaning on contribution to possible teaching the user AAC aids, students with cerebral palsy by whole language approach in natural environment but in artificial situation at script.

This study evaluated the content of Korean vocabulary learning applications with a focus on tablet PC applications. We analyzed 51 Korean vocabulary learning applications. The instruments in this study were developed based on Yoo et al. (2012)' Vocabulary Learning Game Application Evaluation Criteria and Hyun et al. (2013)' Educational Application Evaluation Criteria. Data were analyzed using a t-test and one-way analysis of variance. The main results are as follows. First, each criteria's score was fairly good; the ease of use had the highest scores and the amusement had the lowest scores. Second, there was a significant difference in the interaction by vocabulary teaching approach. Applications based on a whole language-teaching method had higher scores than applications based on a phonics instructional teaching method inducing more operation and with immediate feedback. Third, there was significant difference in the sum of score and each criteria of developmental appropriateness, educational values, amusement, function and interaction by type of learning. Applications of combining type had higher scores in every criteria except for ease of use than applications of description type. These findings provide a preliminary evidence that the systematic Korean vocabulary learning application facilitates preschoolers' vocabulary learning.

A biomechanical approach was carried out to analyze foot-floor reaction forces acting on five male subjects performing a walking task. The task analyzed was walking over an obstacle with the right bare foot. The foot-floor reaction data were measured from a force plate, and then processed using a software developed. The source program was coded in the C language for easier on-line data acquisition and graphic displays. High repeatability was found in the reaction data acquired from three trials by each subject. For obstacle height from 0 to 25 cm, the maximum in reaction force reached up to 1.048 BW in the vertical, 0.174 BW in the anterior-posterior, and 0.054 BW in the medio-lateral components, respectively. A quantity was defined by the difference between two vertical reaction values, and this quantity was found to be proportional to the obstacle height. It was also shown that the whole body motion could be predicted the measured foot-floor reaction data.

This paper proposes a framework for integrated credit risk management system in domestic bank financial institutions. Credit evaluation system, loan processing system, credit monitoring system, and credit risk management system are integrated for efficient and effective risk-adjusted performance management in this framework. Risk exposures, not only for each credit, but also for bank's whole credit portfolio need to be measured and analyzed through the concept of Value-at-Risk (VaR). The effects of changes in credit ratings of individual loaners on bank's credit risk exposure are also considered. We tried to model this integrated credit risk management system by using object-oriented modeling language, UML.

Recently, by the expansion of Industrial Capitalism and the development of Information Technology, the qualify of humans' life came to have various aspects. In this era of variety, among all the different attempts Rem Koolhaas(OMA)'s architectures attract attention for their architecture's new point of view in architectural design. On the basis of the objective fact in the modern world, as a construction which expresses the language naturally, and a democratic architecture of a faithful part for the whole, these kinds of approach shows the similarity and the properties of Neue Sachlichkeit which has appeared in the colloquy and photographs in Germany at the end of the 20th century in the past. The main purpose of this study is to recognize the understanding and development of Neue Sachlichkeit's properties in architecutre - the Neue Sachlichkeit's influence on the architecture from elementerism, Constructivsit International, ABC Group and Holland's 'the De 8 and Opbouw's' architecture's move to the Holland's architecture - in colloquy and photographs from 1910 to 1930 which had the similar aspect and chronological situation of the modern world.

The purpose of this study is to develop a scale for evaluation of Parent's Literacy Interaction Rating Scale (PLIRS) for preschool children and to examine its validity and reliability. The participants of this study were 342 Korean mothers with children of 3 to 5 year olds. The methods for data analysis included item analysis, factor analysis for construct validity, Pearson correlations between PLIRS and two sub tests of EC-HOME for concurrent validity, and Cronbach's ${\alpha}$ for reliability. The item discrimination was determined by comparing the highest and lowest groups using Chi-square (${\chi}^2$), and Cramer's V. The 25 items of the scale were found to be satisfactory in item discrimination. The concurrent validity was also identified by correlation between PLIRS and two sub tests of EC-HOME. Factor analysis revealed that the structure of the PLIRS consisted of three factors: 'open interaction', 'directive interaction', and 'picture-book reading interaction'. 'Open interaction' is based on 'Whole Language Approach', such as 'I have my child write as he/she likes even if they spell wrongly.' 'Directive interaction' is based on 'Code Emphasis Approach', such as 'I have my child take dictation.' 'Picture-book reading interaction' is how parents read picture-book with her/his children, such as 'When I read a picture book to my child, I ask various questions about a book story.' The Cronbach's ${\alpha}$ for internal consistency reliability range was .78 to .87 for three subscales. It was concluded that PLIRS was valid and reliable to examine the literacy interaction between parents and children in home.
