이 연구의 목적은 확률적 관점의 원형이론으로 학습자들이 프로그래밍 과정에서 형성한 프로그래밍 개념의 구조를 이해하는 것이다. 이를 위해 개념(conception)의 의미와 원형이론(prototype theory)을 고찰하고, 대학생 33명이 문제해결 프로그래밍 경험으로 형성한 학습자의 변수(variable) 개념을 개념적 은유(conceptual metaphor) 글쓰기로 자료를 수집하여 분석하였다. 이 연구의 결론은, 1) 개념적 은유(conceptual metaphor) 글쓰기 활동은 프로그래밍 교육 효과를 높이는 교육 방법이고, 2) 학습자의 추상적 속성 형성 경험을 보강해야 하고, 3) 프로그래밍 개념은 집단별로 수준별 개념(multi-level concept)을 형성하고, 4) 프로그래밍 교육에서 기호의 의미에서 발생 가능한 오개념 위험(misconception risk)을 의도적으로 차단해야하고, 5) 프로그래밍 평가 도구는 다양한 속성을 적용할 수 있는지를 확인할 수 있게 개발되어야 한다.

광고연구에서 거시적 접근은 전체의 흐름을 파악하거나 문제를 발견하는 데에 용이하게 해준다. 본 논문은 이러한 거시적 접근으로서 광고를 하나의 TV미디어 컨텐츠로 보고, 사회ㆍ문화적 영향력에 있어서 실제로 수용자들이 인식하는 것은 어떤 것인가를 알아보려는 것이다. 특히 TV컨텐츠 중에서 개인의 가치관 형성에 영향력을 미치는 드라마와 영화를 비교하여 조사해 봄으로써 그 영향력의 실체를 입체적으로 밝혀 보려고 시도하였다. 광고가 갖는 TV미디어 컨텐츠로서의 영향력 측정은 피조사자에게 28개 가치관 항목에 대한 개개인의 영향력을 광고ㆍ드라마ㆍ영화 세 가지에 대하여 응답하게 하였고, 이를 통계처리 하였다. 조사결과, TV미디어 컨텐츠로서의 광고에 대해 유의미한 가치관 항목이 '성취감', '변화 있는 생활', '진취적으로 사는 것'과 같은 것으로 인식되고 있었는데, 이것은 주로 광고를 통해서는 다른 두 개 컨텐츠에 비교되며, 사회ㆍ문화적 측면에서 어떤 변화를 주도하는 것과 새로움, 진취적인 삶의 방식에 대해 영향을 받고 있고, 그렇게 인식하고 있는 것으로 보여진다.

The purpose of this study were to define the degree of performance in health promoting lifestyle and to identify the variable related to performance in health promoting lifestyle of adolescents. The subjects of this study were 469 adolescents in the 4 high schools. The sample data were collected using a purposive sampling method from July 1 to July 27. The collected data were analysed by using descriptive statistics, Pearson's correlation coefficients, and stepwise multiple regression with SPSS PC+ program. The results of this research were as follows. First, The means of performance in the health promoting lifestyle of adolescents revealed total 2.478 ; harmonious relationships 3.045, regular diet 2.236, professional health management 1.332, sanitary life 2.910, self regulation 2.558, emotional support 2.696, healthy diet 2.408, rest and sleep 2.651, exercise and activity 2.491, self actualization 2.466, diet control 2.408. The factor with the highest degree of performance was the harmonious relationships, whereas the one with the lowest degrees was the professional health management. Second, the relationship between the degree of performance in health promoting lifestyle and its related variable were as follows. (1) Performance in the health promoting lifestyle was significantly correlated with self esteem, self efficacy, health conception, perceived health status, mother's health promoting lifestyle, mother's health conception. (2) The most important factor that affects performance in the health promoting lifestyle of adolescents was self esteem. The combination of self esteem, health conception, mother's health promoting lifestyle, self efficacy, perceived health status accounted for 45.2% of the variance in health promoting lifestyle of adolescents.

In this study, about the fatigue life of welded structure material under fluctuation loading, the prediction life which is produced by using the Histogram Recorder System was compared with the experimental life which is produced by the RMC model which is imported by conception of equivalent stress. In this result, this is represented few difference by comparing prediction life which is produced by damage analysis depended on Miner's rule, by using the Histogram Recorder System, with experimental life which is produced by the RMC load model which is imported by conception of equivalent of stress, therefore fatigue life is easily predicted by using Histogram Recorder System, and result of prediction has equivalent accuracy with other method which is more complex than the Histogram Recorder System. Besides the damage which is produced by stress which is high thirty percentage rank in the stress range of damage inducing, is nearly equal to the damage which is induced the rest of seventy percentage, there fore we can see that damage accumulation which is induced few time overload which is effected welded structure material is great.

Deep comprehension of basic mathematical notions and concepts is a basic condition of a successful teaching. Some elements of algebraic thinking belong to the elementary school mathematics. The question "What stays the same and what changes?" link arithmetic problems with algebraic conception of variable. We have studied beliefs and comprehensions of future elementary school mathematics teachers on early algebra. Pre-service teachers from three academic pedagogical colleges deal with mathematical problems from the pre-algebra point of view, with the emphasis on changes and invariants. The idea is that the intensive use of non-formal algebra may help learners to construct a better understanding of fundamental ideas of arithmetic on the strong basis of algebraic thinking. In this article the study concerning arithmetic series is described. Considerable number of pre-service teachers moved from formulas to deep comprehension of the subject. Additionally, there are indications of ability to apply the conception of change and invariance in other mathematical and didactical contexts.

모형론적 귀결 개념은 타르스키의 1936년 논문에 기원을 두고 있다고 보통 말한다. 하지만 에치멘디는 이를 부정한다. 이 논문은 1936년 논문에 나와 있는 타르스키의 정의가 과연 표준적인 모형론적 귀결 개념에서 받아들이는 것과는 다른 고정 도메인 견해에 기반을 둔 것인지 아니면 그것과 같은 가변 도메인 견해에 기반을 둔 것인지를 둘러싸고 전개된 논란을 다룬다.

This research aims to analyze on the instruction effectiveness of ability grouping based on 'setting' and the result is as following. Superior group had a positive effect from the aspect of self-conception, satisfaction on class, and learning attitude while average and inferior group had a negative effect from the aspect of self-conception, satisfaction on class, and learning attitude. Therefore, the point seems to be that ability-grouping class based on 'setting' only helps the students in the superior group. Therefore, it is necessary to reconsider the educational policy of variable curriculum classroom by achievement Level implemented by current ability-grouping. A method should be prepared to help all the students in superior, average, and inferior level.

This study investigated trends in university students' acceptance of family diversity, familism, family strengths. Participants in this study were 388 university students (193 male, 195 female). The major findings were as follows: Respondents' recognition of family concept is modified from traditional family notion to modern conception. The general trends regarding the level of familism showed that males' level was higher than females'. The respondents' family strength was influenced by a blood permanency of father, family priority, reverence for parent and the tie that bind child, functional perceptions of family. The most important variable in terms of influence on university students' family strength was that of familism. These results implied that the familism was partly influential to family strengths.

The domestic ports become less competitive for the out of dated equipments and inefficient information system. Specially, Inchon Port, which is the second largest port of Korea, has the point at issue such as the excessive logistics cost because of the limit of handling capacity and the chronic demurrage. In this paper to develope the simulation programs the basic input parameters such as arrival intervals, cargo tons, service rates are analyzed and the probability density functions for there variable are estimated. Also to perform the conception of continuous berth utilization, the berth and cargo classification is reconstructed. And the more actual simulation is realized by using more detailed depth representation of water The simulation model is executed based on the knowledge base and database, and is constructed using Visual Basic and Access database. Simulation results reveal that this study suitably reflect the real berth operation and waiting time of ships is shortened.

본 연구에서는 고등학생 165명을 대상으로 학생들의 분자 구조에 대한 개념 이해도와 인지 변인들 사이의 관계를 조사하였다. 학생들이 두 학기 동안 '고등학교 화학 II 과목을 학습한 후, 분자 구조에 대한 개념, 공간 지각 능력, 논리적 사고력, 기억 용량, 학습 접근 방식 검사를 실시하였다. 연구 결과, 분자 구조 개념에 대한 학생들의 이해는 불완전하였으며, 몇 가지 오개념이 발견되었다. 개념 검사 점수는 모든 인지 변인 검사 점수들과 유의미한 상관이 있었다. 개념 이해에 대한 인지 변인들의 예언력을 조사하기 위해 중다 회귀 분석을 실시하였다. 유의미 학습 접근 방식이 가장 큰 예언력을 나타내었고, 논리적 사고력, 기계적 학습 접근 방식, 기억 용량의 순으로 예언력이 컸다. 그러나 공간 지각 능력은 예언력이 없었다.
