The purpose of this study was to develop Graphic Organizer as Advance Organizer. The 'Menu Planning and Food Selection' unit of second grade middle school Technology & Home Economics(revised curriculum of 2007) was selected as the study subject. The course of abstracting an essential education element got done $3^{rd}$ times. It abstracted the first essential education elements to analyze the presented sentence or a concept with the educational contents factor which is on the achievement standard of the area of dietary life from 5grade to 10grade in curriculum revised in 2007. The first 4 essential education elements selected were superiority and cultural value of Korean traditional meal, preparing a balanced diet for the family, food purchasing, and food selection based on the various information'. It abstracted second essential education elements that it concretized the first content factor on a unit of this study and solved overlapping when it was happened at the first contents factor and made connecting with between grade. The $3^{rd}$ essential education elements abstracted to classify the contents which abstracted essential education elements in second. And, it developed Graphic Organizer on a unit of 'Menu Planning and Food Selection' in eight-grade Technology & Home Economics based on the abstracted essential education elements. Graphic Organizer was developed in according to order of the way for making on a Concept Map of Heo In Sook(2000). Developed Graphic Organizer is all of 10 which are 'nutrition value on food of the season', 'harmony and combination of food', 'natural dressing and a garnish', 'the recipe', 'fermented food', 'a traditional instrument and a vessel', 'actor of food harm', 'present food', 'food quality certification' and 'selecting food with food information'.

This paper examines the aspects of the inferences between the dimensional terms in Korean, and attempts to give an account of the inference patterns based on the interaction of gestalt and position properties of spatial objects. Following Lang (1987) and Lang, Carstensen & Simmons (1991), we advance the idea that the inferences are possible for the same axis of a spatial object, if some contextually induced positional specifications are reversed to the inherent proportion schema. Two simple inference rules are proposed and justified. They are applied under the assumption that the inferences of the dimensional terms are drawn in a unidirectional way, i.e, from the Primary Perceptional Space to the Inherent Proportional Schema.

The purpose of this research was to develop an un-tact group counseling program to deal with the conflicts in the relationship of unmarried couples and to verify the effect of the program for improving emotional cognition and emotion regulation of unmarried couples. The research procedure consisted of the program development step and the program verification step, and in detail, 8 steps of program development processes were established. The subjects of the research were 11 unmarried couples, and 4 group were organized. The group counseling program was conducted once a week (2 sessions), a total of 10 sessions for 5 weeks. The effect was analyzed quantitatively and qualitatively. As a result of quantitative analysis, the participant's relationship satisfaction was significantly improved and there was a significant change in some relationship emotional schemas of participants. As a result of qualitatively analysis through participant's program review, participant's emotional understanding and the couple relationship were improved, and the group effect of the couple group counseling was found. Finally, the significance and limitations of this study were presented.

This study presents how two eighth grade students generated their own algorithms in the context of fraction measurement division situations by modifications of unit-segmenting schemes. Teaching experiment was adopted as a research methodology and part of data from a year-long teaching experiment were used for this report. The present study indicates that the two participating students' construction of reciprocal relationship between the referent whole [one] and the divisor by using their unit- segmenting schemes and its strategic use finally led the students to establish an algorithm for fraction measurement division problems, which was on par with the traditional invert-and-multi- ply algorithm for fraction division. The results of the study imply that teachers' instruction based on understanding student-generated algorithms needs to be accounted as one of the crucial characteristics of good mathematics teaching.

구성주의 수업은 삶의 경험 혹은 나의 문제로 전환된 문제를 학습주제로 하여, 교사와 학습자, 학습자간에 상호성과 상보성이 전제된 대화화 협력을 통해, 맥락에 적합한 지식을 구성하는 활동이라 할 수 있다. 구성주의 지리교육은 지리학을 위해 지리적 지식을 구성하는 것이 아니라, 지리적 삶을 위해 지리적 지식을 구성하는 것이다. 이것은 지리적 맥락과 맥락의 구성에 충실할 때 가능해 진다. 방법론적으로는 생활 주변에서 볼 수 있는 지리적 사상을 학습대상으로 하여, 이들을 그림이라는 상징을 통해 학습자 스스로 맥락에 따라 구성, 재구성하는 과정 속에 지리적 지식이 구성되게 하는 것이다.

This study explores the effects of an video-recording English speaking task model on learners. The learning model, a form of mobile learning, was developed to facilitate the learners' output practice applying advantages of a smartphone and Text-to Speech. The survey results shows the positive effects of the speaking task on the domain of pronunciation, speaking, listening, writing in terms of students' confidence, as well as general English ability. The study further examines the possibilities and limitations of the speaking task in assisting Korean learners improve their speaking ability, who do not have sufficient exposure to English input or output practice due to the situational limitations where English is learned as a foreign language.

In this paper, we describe a fuzzy threshold selection technique for feature extraction in digital color images. this is achieved by the formulation a fuzzy inference system that evaluates threshold for feature configurations. The system uses two fuzzy measures. They capture desirable characteristics of features such as dependency of local intensity and continuity in an image. We give a graphical description of a nonlinear sketch feature extraction filter and design the fuzzy inference system in terms of the characteristics of the feature. Through the design, we provide selection method on the choice of a threshold to achieve certain characteristics of the extracted features. Experimental results show the usefulness of our fuzzy threshold inference approach which is able to extract features without human intervention.

This study was to find characteristics of argumentation derived from a discourse in a math-gifted 5 grade class, which was held for finding a Pick's formula using Geoboard function of TI-73 calculator. For the analysis, a video record of the class, transcript of its voice record, and activity paper were used as data and Toulmin's argument schemes were applied as analysis standard. As a result of the study, we found that the graphing calculator helped the students to create an experimental environment that graphing a grid-polygon and figuring out its area. Furthermore, it also provided a basic demonstration through 'data->claim' composition and reasoning activities which consisted of guarantee, warrant, backing, qualifier and refutal for justifying. The basic argumentation during the process of deriving the Pick's theorem by the numbers of boundary points and inner points was developed into a 'collective argumentation' while a teacher took a role of a conductor of the argumentation and an authorizer on the knowledge at the same time.

산악지역을 관통하는 도로의 경우 그 특성상 절토 후 도로를 시공하는 경우가 자주 있으며 때로는 매우 긴 구간에 일조가 적게 나타나 음영이 오래 지속되는 곳이 발생한다. 본 연구는 GIS를 이용하여 도로의 노선계획시 예상되는 일조영향을 평가하여 정확한 데이터를 제공하고자 한다. 실험대상지역을 선정하고 수치지형자료의 변환을 통하여 3D 지형 메쉬데이터를 작성하고 동일좌표체계의 도로선형자료를 반영하여 정확한 도로모델링을 생성하므로써 도로의 각 지점별 일조영향분석을 위한 기초자료를 구축하였다. 또한 도로노면상의 음영시간을 계산하고 일영이 도로 전체에 어느 정도 유지되는지를 가시적으로 모델링화하여 계절별 시간대별로 도식화하므로써 판단자의 시각적 분석을 가능케 하였다.
