Distributed programming can be greatly simplified by language support for distributed communication. Many web browsers now offer some form of distributed objects and the number and types of them are growing daily in interesting and innovative ways CORBA IDL and Java RMI, the representative of distributed object model, support different approaches for distributed computing environments. CORBA approach does not support the application generated by java RMI, even though it supports multiple programming languages. Object translation system between RMI to CORBA is designed and implemented for interoperability of distributed objects on the two different distributed programming environments. Suggested system is considered binding, inheritance, polymorphism, object passing, and callback which are key properties on the distributed objects. Translation System we suggested is implemented on the Window/NT(version 4.0) with Java Development Kit(version 1.1.6).

The seismic performance of masonry-infilled frame structures, typical in school buildings, is evaluated through equivalent strut models. A bare frame model, concentric strut models and eccentric strut models with various material characteristics available in the literature are analyzed. Displacements and damage states at the performance points obtained by the capacity spectrum method show great differences among the models. Infill walls act positively in concentric strut models and negatively in eccentric strut models at the performance points for a given seismic demand. In addition, the behavior at the ultimate displacements shows considerably different strengths, inter-story drifts, and numbers and locations of damaged members among various modeling methods and material strengths.

Functional thinking is a central topic in school mathematics and the purpose of teaching functional thinking is to develop student's functional thinking ability. Functional thinking which has to be taught in elementary school must be the thinking in terms of phenomenon which has attributes of 'connection'- assignment and dependence. The qualitative methods for evaluation of development of functional thinking can be based on students' activities which are related to functional thinking. With this purpose, teachers have to provide students with paradigm of the functional situation connected to the other subjects which have attributes of 'connection' and guide them by proper questions. Therefore, the aim of this study is to find teaching method for functional thinking by situation posing connected with other subject. We suggest the following ways for functional situation posing though the process of three steps : preparation, adaption and reflection of functional situation posing. At the first stage of preparation for functional situation, teacher should investigate student's environment, mathematical knowledge and level of functional thinking. With this purpose, teachers analyze various curriculum which can be used for teaching functional thinking, extract functional situation among them and investigate the utilization of functional situation as follows : ${\cdot}$ Using meta-plan, ${\cdot}$ Using mathematical journal, ${\cdot}$ Using problem posing ${\cdot}$ Designing teacher's questions which can activate students' functional thinking. For this, teachers should be experts on functional thinking. At the second stage of adaption, teacher may suggest the following steps : free exploration ${\longrightarrow}$ guided exploration ${\longrightarrow}$ expression of formalization ${\longrightarrow}$ application and feedback. Because we demand new teaching model which can apply the contents of other subjects to the mathematic class. At the third stage of reflection, teacher should prepare analysis framework of functional situation during and after students' products as follows : meta-plan, mathematical journal, problem solving. Also teacher should prepare the analysis framework analyzing student's respondence.

본 논문은 대순사상의 선화(善化)사상을 살펴보고 그 주체성을 밝히는데 목적이 있다. 『전경』에서는 어떻게 선을 드러내고 행하며 더 나아가 선으로 중생을 교육하고 천하를 교화하는가 하는 선화의 문제를 다루고 있는데, 이는 곧 대순진리회의 핵심 사상으로 볼 수 있다. '선화'사상은 세 가지 내용으로 설명할 수 있다. 첫째, 도덕적 의미에서 만물을 도와서 교화시키거나 만물을 크게 이롭게 하는 속성을 가지고 있다. 둘째, 상선(上善)의 덕 외에도 상선의 법이 필요한데, 이는 '선을 행하는 목적'에 부합하고 또한 선을 행하는 법칙을 지키는 실천방법과 절차를 말한다. 셋째, 가장 높은 차원에서의 '선'은 윤리도덕의 단계를 초월한다. 이에 대순진리회의 '선화'사상을 살펴보면 첫째, 대순진리회의 목적인 무자기, 포덕천하, 광제창생, 보국안민, 지상천국건설에 나타난 문자의 표면적 의미와 내재적 의미는 모두 '선화'의 내용에 포함된다. 둘째, 대순진리회 목적의 실현은 그 종지와 신조에 의거하는데, '합덕·조화·해원'과 사강령(四綱領)과 삼요체(三要諦)에도 '선화'의 의미가 포함되어 있다. 셋째, 대순진리회의 목적은 도인들의 구체적 행위를 통해 실현되는데, 수도와 공부의 필요성과 규범 속 그리고 상제와 도주 조정산(趙鼎山)의 창교(創敎)나 선교(宣敎) 등 구체적인 실례에서도 '선화'의 원칙이 분명하게 드러나 있다. 대순진리회의 '선화'사상은 전형적이고 신성한 종교 도덕적 특징과 일상생활의 의미가 담긴 사회 윤리적 특징이 있으며, 또한 윤리를 초월하고 진선(盡善)을 추구하는 궁극적 목적의식과 이론적 깊이가 있다. 대순진리회 '선화'사상의 주체성과 이론구조를 분석하면 다음과 같다. 첫째, 대순진리회의 '선화'사상에서는 무엇보다 윤리 도덕적 측면에서의 선의 배양과 실천을 중시한다. 둘째, 대순진리회의 '선화'사상은 윤리도덕의 선을 실천하는 법문(法門)을 제시하였다. 셋째, 대순진리회의 '선화'사상은 수도의 최종 목적인 대선(大善)·지선(至善)·진선(盡善) 등을 추구하고 실현할 것을 강조하였다. 선화사상이 나타내는 핵심인 '선덕'과 이로부터 발전된 '선행선법(善行善法)'이 결국 윤리도덕의 차원을 초월하였음을 알 수 있다.

Vast amount of XML documents raise interests in how they will be used and how far their usage can be expanded. This paper has two central goals: 1) easy and fast retrieval of XML documents or relevant elements; and 2) efficient and stable management of large-size XML documents. The keys to develop such a practical system are how to segment a large XML document to smaller fragments and how to store them. In order to achieve these goals, we designed SCOF(Service-centric Object Fragmentation) model, which is a semi-decomposition method based on conversion rules provided by XML database managers. Keyword-based search using SCOF model then retrieves the specific elements or attributes of XML documents, just as typical XML query language does. Even though this approach needs the wisdom of managers in XML document collection, SCOF model makes it efficient both retrieval and management of massive XML documents.

Singaporean students have demonstrated their superior mathematical achievement and positive mathematical dispositions. Against this background, this study compared Korean elementary mathematics textbooks with Singaporean counterparts focusing on the geometry and measurement strand. The analysis was conducted in many aspects, including an overall unit structure, the contents to be covered in each grade, and the methods of introducing essential learning themes. The textbooks were also compared and contrasted with regard to the main characteristics of constructing mathematical contents. Whereas Korean textbooks used block teaming, Singaporean textbooks used repeated teaming. The latter also employed the activity of classifying multiple figures as the main method of introducing concepts. Whereas Korean textbooks consist of typical examples of figures, Singaporean counterparts include various examples consistent with the principle of mathematical variability.

With the introduction of the system of recognizing masters of craft and performance skills in 1970, the principle of "preserving the original form," which was already in general use, was adopted as a legal principle in the Cultural Heritage Protection Act. While the concept "original form" can be related to tangible elements of heritage through the Act, the intangibility of craft and performance skills does not allow their pinpointing at a particular temporal period or the identification of a particular master from the past as the basis of an original form. Therefore, those craft or performance skills that are available at the point of recognition of relevant masters must serve as the basis of the original form for the intangible heritage concerned. This means that the principle of preserving the original form of intangible heritage has been implemented not based on a fundamental form of materiality, but rather on the craft or performance skills that may be held by a master at the time of his/her recognition as a "temporary original form." This principle has been observed through intangible heritage transmission and education policies for recognized masters and their trainees, contributing to establish an elitist transmission environment in which public were denied to join the education on intangible heritage. Even with policies guided by the principle of preserving the original form, designated craft and performance skills have been transformed contingent upon given social and environmental conditions, thus hindering the preservation of the original form. Despite the intrinsic limitations of the principle of preserving the original form when applied to intangible heritage, this principle has served as a practical guideline for protecting traditional Korean culture from external influences such as modernization and Westernization, and also as an ultimate goal for the safeguarding of intangible heritage, engendering actual policy effects. The Act on the Safeguarding and Promotion of Intangible Cultural Heritage that comes into effect in March 2016 takes the constantly evolving nature of intangible heritage into consideration and resultantly adopts a concept of "essential form" (jeonhyeong) in place of "original form" (wonhyeong). This new concept allows for any transformations that may take place in the environment surrounding the intangible heritage concerned, and is intended to mitigate the rigidity of the concept of "original form." However, it should be noted that "essential form," which is manifested as the unique significance, knowledge, and skills delivered by the intangible heritage concerned, should be maintained according to the guidelines and principles related to heritage conservation. Therefore, the new concept can be understood not as a rupture, but more as a continuum of the concept of "original form."
