This study is to investigate the development of 'Educational Larchiveum' especially for the Kyeongsangnam-do Provincial Office of Education. 'Educational Larchiveum' means Educational Archives including some museum and library functions. This study begins with articulating that why the provincial offices of education should establish their own archives despite of legal obligation. It draws the roles of 'Educational Larchiveum' and its environmental requirements, based on analysing the Archives/Museum case of Toronto District School Board Education. Finally it suggests that how Gyeongsnam-do Offie of Education can establish the 'Educational Larchiveum' in condition of integration of the Gyeongsnam-do Educational Museum and the private educational museum(Park Yeon-mook Educationl Museum).

The act of writing a unit test is more an act of design than of verification. It is also more an act of documentation than of verification. The act of writing a unit test closes a remarkable number of feedback loops, the least of which is the one pertaining to verification of function. Unit testing is a fundamental practice in Extreme Programming, but most non-trivial code is difficult to test in isolation. Normal unit testing is hard because It is trying to test the code from outside. On the other hand, developing unit tests with Mock Objects leads to stronger tests and to better structure of both domain and test code. In this paper, I first describe how Mock Objects are used for unit testing of federation integration. Then I describe the benefits and costs of Mock Objects when writing unit tests and code. Finally I describe a design of Mock federate for using Mock objects.

With a remarkable growth and expansionof Internet, the security issues emerged from intrusions and attacks such as computer viruses, dental of servives and backings to destroy intormation have been considered as serious threats for Internet and the provate networks. To protect networks from those attacks, many nendors have developed various security systems such as firewalls, intrusion detection systems, and access control systems. However managing those systems individually requres too much work and high cost. Thus, integrated security managemanet and eatabliashment of consistent security policy for various security products has become more important. In this paper, we propose integrated security manabement system called WISMSF(Web based Integrated Security Management System for Fireswalls) to monitor and contro various kinds of firewalls WISMSF consists of three components-clients, integrated engine, and agents. It supports the transparent management functions of security products, easy ways of defining security policies, and simple expansion of managed ranges.

Recently the car attached many ECUs and entertainment devices to provide the easiness maintenance and driver's convenience. CAN and MOST networks have been used to manage and control those devices in the car. Wireless network also has been established to receive information from external. These days a car navigation system with GPS is being integrated with CAN, MOST and Wireless network. In these circumstances, the car navigation system can have HMI function to integrate and control the car networks' devices. To solve the GPS problems such as positioning errors or losing signals from satellites in the tunnels and urban canyons, this paper designs and implements a method for positioning vehicle by using the sensing data of sensors and Wi-Fi devices based on this integrated environment.

The purpose of this study is to quickly collect and analyze information generated in real-time at disaster sites to propose an integrated plan for an on-site support system that can support accurate disaster site situation identification and decision-making, and to review field applicability through prototype simulation. Accordingly, information collection, sharing, and convergence technologies that can be used at disaster sites were reviewed, and a plan for integrating a smart disaster site support system that can create an efficient flow of information resources and information necessary for the entire stage of disaster management was presented. In order to examine the possibility of operating the system with a prototype manufactured based on the integration plan, simulations were conducted based on the storm and flood disaster scenario, and it was confirmed that various functions in the system were implemented normally and displayed on the GIS situation board. Through this study, it is expected that efficient and active disaster response will be possible in a rapidly changing disaster environment.

The purpose of this study is to compare and analyze phonetic items such as the phonemic system, phonological rules, and pronunciation descriptions and notations incorporated in the textbooks. Based on our analysis results, we point out the problems related to pronunciation education, and suggest directions for improvement. First, the presentation order of consonants and vowels in the phonological systems sections of each textbook was different. We recommend that a standard for consonant and vowel presentation order should be prepared, but that this standard should take into consideration the specific purpose of the textbook; the learning strategies and goals, as well as the possibility of teaching and learning. Second, similar to phonemic systems, the presentation order of phonological rules was different for each textbook. To create a standard order for phonological rules, we have to standardize the order of presentation of rules and determine which rules should be presented. Furthermore, when describing phonological rules, the content should be described in common and essential terms as much as possible without the use of jargon. Third, in other matters of pronunciation, there were problems such as examples for pronunciation and lack of exercises. Regarding this, we propose to provide sentences or dialogues as examples for pronunciation, and to link these to various activities and other language functions for pronunciation practice.

With the rapid growth of network technology, two or more products from different vendors are integrated and interact with each other to perform a certain function in the latest systems. Thus. interoperability testing is considered as an essential aspect of correctness of integrated systems. Interoperability testing is to test the ability of software and hardware on different machines from different vendors to share data. Most of the researches model communication system behavior using EFSM(Extended Finite State Machines) and use EFSM as an input of test scenario generation algorithm. Actually, there are many studies on systematic and optimal test case generation algorithms using EFSM. But in these researches, the study for generating EFSM model which is a foundation of test scenario generation isn't sufficient. This study proposes an EFSM generating technique from informal requirement analysis document for more complete interoperability testing. and implements prototype of Test Case Generation Tool generating test cases semi-automatically. Also we describe theoretical base and algorithms applied to prototype implementation.

If the philosophy of the curriculum is changed when the curriculum is revised, discussion about knowledge viewpoints in the changed philosophy is needed. The purpose of this thesis is to analyze elementary mathematics textbooks(EMT) based on the perspective of constructivism knowledge as basic philosophy of the 7th curriculum and the 2007 revised curriculum and to present aim of textbooks development through the results. According to the results, the number and operation units of 1st and 2nd grades of EMT compiled according to the 7th curriculum and the 2007 revised curriculum didn't reflect the perspective of constructivism knowledge as the philosophy of the curriculum. From the analysis, EMT were not composed so as to agree the perspective of constructivism knowledge that emphasize concepts, conceptua1 principles, variety, integration.

Recently, a method of fabricating an esthetic anterior fixed prosthesis by integrating data such as three-dimensional facial scan and jaw motion to form a virtual patient with dynamic occlusion has been introduced. This enables smooth communication with patients during the diagnosis process, improves the predictability of esthetic prosthetic treatment, and lowers the possibility of occlusal adjustment. In this case report, a virtual patient with dynamic occlusion was created in which the results of the treatment were simulated, and esthetic maxillary anterior fixed prosthesis was fabricated. With the aid of the virtual patient, the final restorations were satisfactory both in terms of esthetic and function.
