The success of XML(eXtensible Markup Language) is primarily based on its flexibility : everybody can define the structure of XML documents that represent information in the form he or she desires. XML is so flexible that XML documents cannot be automatically provided with an underlying semantics. Different tag sets, different names for elements or attributes, or different document structures in general mislead the task of classifying and clustering XML documents precisely. In this paper, we design and implement a system that allows checking the semantic-based similarity between XML tags. First, this system extracts the underlying semantics of tags and then expands the synonym set of tags using an WordNet thesaurus and user-defined word library which supports the abbreviation forms and compound words for XML tags. Seconds, considering the relative importance of XML tags in the XML documents, we extend a conventional vector space model which is the most generally used for document model in Information Retrieval field. Using this method, we have been able to check the similarity between XML tags which are represented different tags.

As craft is representing the historical culture of one country based on the old cultural characteristics and traditions of the regions in our life and is also representing the contemporary cultural culture, the interest in the crafts is becoming bigger and bigger as days pass by. However, despite this potentiality for growth, the craft that we encounter is not reflecting the ever-changing environment of the times, is failing to go beyond the folk art industry level of 1970s to 1980s. Although most of the industrial craft corporations have highly developed craft technology, but the products are not sublimated into marketable products. Also, so far schemes for development of industrial craft have not been many and studies on industrial craft in a sense of the design management have not been performed. Accordingly, this study intends to survey the effect of the design management strategy on the industrial craft product purchase intention in the industrial craft. The main contents comprehended in the study process are as follows. The design management strategy affects the industrial craft product purchase intention. Among the lower elements of the design management strategy, which are cost reduction-oriented design strategy, image-oriented design strategy and the market-oriented design strategy, the image-oriented design strategy and the market-oriented design strategy showed to affect the industrial craft product purchase intention. Especially, the image-oriented design strategy showed to affect the industrial craft purchase intention more than the market-oriented design strategy does.

The product convergence and complex application environment raise the need of multi-modal interface which enables us to interact products through various human senses. The sense of vision has been used predominantly more than any other senses for the traditional and general information gathering situation, but in the future which will be developed based on the digital network technology, the practical use of the various senses will be desired for more convenient and rational usage of the information appliances. The sense of auditory which possibility of practical use is becoming higher than ever with the sense of vision, the possible usage will be developed broader and in the various ways in the future. Based on this situation, the characteristics of the written language and the colloquial language and the comparative analysis of the difference between male and female's reaction for each language were examined through this study. To achieve this purpose, the literature research about the diverse components of the language system was peformed. Then, some peculiar characters of the sense of vision and auditory were reviewed and the appropriate experimentation was planned and carried out. The result of the accomplished experimentation was examined by the objective analysis method. The main results of this study are as follows: first, the reaction time for written language is shorter than colloquial language, second, there is a partial difference between the male's and female's reaction for those two stimuli, third, there is no selection bias between the sense of sight and the sense of hearing. I think the continuous development of the broad and diverse ways of study for various senses is needed based on this study.

For spatial analysis and decision-making based on territorial and urban information, technologies on 3D GIS with digital image data and photo-realistic 3D image models to visualize 3D modeling are being rapidly developed. Currently, satellite images, aerial images and aerial LiDAR data are mostly used to build 3D models and textures from oblique aerial photographs or terrestrial photographs are used to create 3D image models. However, we are in need of quality 3D image models as current models cannot express topographic and features most elaborately and realistically. Thus, this study analyzed techniques to use aerial photographs, aerial LiDAR, terrestrial photographs and terrestrial LiDAR to create a 3D image model with artificial features and special topographic that emphasize spatial accuracy, delicate depiction and photo-realistic imaging. A 3D image model with spatial accuracy and photographic texture was built to be served via 3D image map services systems on the Internet. As it was necessary to consider intended use and display scale when building 3D image models, in this study, we applied the concept of LoD(Level of Detail) to define 3D image model of buildings in five levels and established the models by following the levels.

In correctional facilities with majority of occupants in custody, the safe evacuation guide without getaway accidents should be very important due to complexity in escape paths. Fire causes are various in correctional facilities, for example, arson fire is a major cause in mental treatment facilities, however, old facilities or carelessness of flammable materials consist of fire causes in jail facilities. Both types of correctional facilities are the same in terms of many casualties from the fire cases. The thesis focus on escape paths and evacuation guide plans on the basis of analysis on fire cases and structural vulnerability, and then an electronic unlocking system is concededly installed for safe evacuation of occupants in custody without getaway accidents. Especially, the effect of the electronic unlocking system is going to be analyzed on the basis of RSET (required safe egress time) in order to realize for the occupants to evacuate safely to the front yard in case of emergency. In conclusion, if electronic security allowed system with USN (Ubiquitous Sensor Networks) technology should be installed in multi-storey correctional buildings, it is proposed that the occupants in custody might be a guided safely without getaway trials.

System developments by components are accomplished by creating new software based on independent components having respective function. Generally, component-based software developments are expected to obtain profits caused by reuse of software, such as improvement of quality, rapid development, and efficiency of maintenance. In a component-based system, the most important goal and also key to success is to identify and construct high quality components that may increase reusability. Therefore, it is necessary for component developers to understand strong and weak points of existing component development methodologies in the aspect of identification of component, and to select the most appropriate methodology for the system to be constructed. It is also necessary for component developers to develop a new methodology enabling effective identification of independent components through modification and/or complementation of existing methodologies. The modification and complementation needs comparison and analysis of various existing methodologies. Accordingly, the this paper is to provide explanation for some widely used methodologies representing the existing component-based software development methodologies such as RUP(Rational Unified Process) of Rational company［1,9］, CBD96 of Computer Associates company［2,3］, UNIFACE of Compuware company［5］, and UML components methodology derived from extending of the component developing method of CBD96 by Cheesman and Daniels［4］. The this paper is also to point out respective problems of the representative existing methodologies. Furthermore, component identification methodologies are compared and analyzedon the whole through this paper.

This study examined the effect of bilingual bicultural home environment and mother's command of Korean language on their participation in child rearing as well as on children's developmental outcomes. We carried out Analysis of Covariance Structure using the 1st year(2011) data of Gyeonggi Education Welfare Panel, which consists of 459 matched pairs of immigrant women and their 5th~6th grade children living in Gyeonggi-do. The results indicated that when the immigrant mother has good command of Korean language and the children are exposed to their maternal culture and language, mothers tend to actively participate in child rearing and this in turn has positive effects on developmental outcomes of their children. These results demonstrate that Korean language programs targeting immigrant women by marriage are important not only for assisting their employment and adaptation but also for enhancing parenting behaviors in multicultural families. Moreover these findings suggest that we need to understand the bilingual bicultural home environment in these families as a significant resource that contribute to their children's developmental outcomes and not as a risk factor to their adaptation, as it has frequently been viewed.

Environmental value is essential to the survival and development of humans. Environmental value and its importance are being emphasized, and related disputes are being expanded. The concept of green logistics is understood to be the same as that of the environment. As a way to preserve nature and engage in sustainable development, green logistics includes all logistical activities for protecting nature and minimizing or reducing behaviors that harm the environment for all processes, including using and reusing products and abolishing the search for resources by final users. All areas of human activity, such as the political, economic, social, and cultural sectors, strive to protect and preserve the environment and nature. In particular, the preservation of the environment shall be stressed in the economic activities that produce various products and expand the value added, and similarly for the social aspects. Green (environment) logistics aims to protect the environment and expand the prevention of environmental destruction and minimization on Earth. Some important cases and experiences that were introduced and applied in major countries are summarized. This research reviewed previous studies and the concepts of green logistics, including at ports, which represent a key sector of logistical activities. In this paper, air and water pollution at Incheon Port were investigated, and alternatives and system figures related to improving environmental logistics regarding three dimensions-country, company, and civil society-are recommended.

Recently, the demand for electricity is gradually increasing due to the rapid industrial development and the improvement of living standards. In the case of Korea, which is highly dependent on fossil fuels due to such a surge in electricity demand, reduction and freezing of greenhouse gas emissions due to international environmental regulations will immediately lead to a contraction in industrial activities. Accordingly, there are many difficulties in competition with advanced countries that want to link the environment with the country's industrial production activities, and the development of alternative energy as a countermeasure is of great interest around the world. Among these new power generation methods, small-scale power generation facilities with relatively small capacity include photovoltaic generation, wind power generation, and fuel cell generation. Among them, the fuel cell attracts the most attention in consideration of continuous operation, high power generation efficiency, and long-term durability, which are important factors for practical use. Therefore, in this paper, the fuel cell power generation system was researched and constructed by designing the power conversion circuit necessary to finally obtain the AC power used in our daily life by using the DC power generated from the fuel cell as an input.
