The purpose of this study was to investigate how congruently the learning objectives of Earth Science I textbooks match the 2009 revised Earth Science curriculum. For this purpose, we classified the learning objectives of curriculum and textbooks were into three factors including ability, cross-cutting concepts, and behavioral verbs. The text data were analyzed using the semantic network analysis method. The results are as follows. The learning objectives of textbooks with regard to ability factors mainly emphasized the cognitive and affective domain. In addition, the ability of inquiry performance was emphasized in the learning objective of the curriculum. The textbooks used various sub-frame of cross-cutting concepts in comparison with the curriculum. Both textbooks and curriculum used the term 'comprehension' the most as behavioral verbs. However, most behavioral verbs just remained at the level of cognitive system.

One of the main objects of geometry in mathematics education is to improve students' geometric intuition capability and logical reasoning capability based on them. A visual element related to intuition plays an important role in teaching and learning of geometry. Therefore, in this research, we focus on the development of multimedia title available to dynamic operation about visual elements and verify of effect of its application. This title for the learning of "the Pythagorean theorem and its practical use" in the third grade of middle school is designed and implemented by an authoring tool, Toolbook. And it enables learners to study mathematics individually and can be applied to the educational field, too. And we taught two groups, the applied group and the compared one of the second grade of middle school and surveyed Questions and evaluated study achievement. We calculated study achievement of two groups on t-test using SPSS. As the result, we knew that the applied group is higher than the compared one in the study achievement and provision of dynamic operation possibility on visual elements make students know very high learning effect and help improvement of intelligent capability.

When the material strength and ductility of shear studs is sufficient to carry the interface shear force, the composite beam can behave safely without premature structural failure in the interface and without ultimate moment reduction. In this study, the influence of the deformation capacity of shear studs embedded in high-strength concrete on structural behavior and design condition of composite beam is analyzed using FEM. In the analysis, load type, degree of shear connection and arrangement of studs are considered as analysis parameters. According to analysis results, in the case of partial interaction,the deformation capacity of studs embedded in high-strength concrete should be considered together with material strength. Especially in the case of uniform arrangement of studs and uniformly distributed load, a minimum available degree of shear connection is restricted by the deformation capacity of studs. In this case,shear studs should be arranged in consideration of the distribution of shear force at the composite section.

80년대 골드랫 박사에 의해 이론이 소개된 이후, 북미와 유럽 지역에서 많은 학자와 기업가들에 의해 연구, 현장에 적용되면서 오늘날 경영혁신 기법들을 주도하는 이론으로 자리잡은 제약이론(Theory of Constraints)은 최근에야 비로소 국내에 소개되고 있는 실정이다. 하지만 소개된 대부분의 연구가 TOC를 구성하는 여러 엔진 중 DBR에 국한된 것들이며, DBR 스케줄링 역시 아직은 이론적 연구에 그치고 있다. 본 연구에서는 기존의 여러 DBR 스케줄링 연구에서 보여진 한계, 즉 제약자원을 선정하는 데 있어, 자원이 가진 부하비율(부하/능력)만을 선정의 기준으로 고려하는 것에서 벗어나 실제 생산현장에 존재할 수 있는 여러 요소를 고려한 스케줄링 방법을 제시하였다. 각 제약자원들의 중요도를 고려하는데 있어서, 객관적 요소와 주관적 요소를 분류한 후 여러 전문가가 각각의 주관적 요소에 부여된 값을 다구찌 기법에서 이용하는 SN비로 계산하고 그 값들을 정규화 하였고, 주관적 요소와 객관적 요소를 위한 가중치 또한 SN비로 계산하고 그 값들을 정규화하는 방법을 제시하였다. 이 방법은 여러 요소들을 고려한 제약자원의 결정에 있어서 다른 요소들에 대한 다수의 전문가의 의견 통합을 시도하였고, 동시에 제약자원 결정에 있어서 임의의 요소에 전문가들이 부여한 값들의 평균이 크고 그 값들이 차이가 적은 즉, 거의 일치한 평가를 내리는 자원을 제약으로 선정하고 스케줄링하는 방법을 시도하였다.

This paper analyzes the differences in the service quality priorities of air cargo service providers and customers. After having identified what constitutes the decisive factors with regards to air cargo service quslity, research was carried out to evaluate the differences in the service quality priorities of air cargo service providers and customers. Moreover, this paper analyzes these differences by separating air cargo service providers into Korean and international air cargo service providers. In order to attain the objectives of this research, the air cargo service sectors were divided into three general categories: supply capability(H/W), service accountability, and competitiveness of service fees and management capability(S/W). The researchers then placed 6 different criteria into each service category, for a total of 18. The evaluation of the service quality priorities of air cargo service providers and customers revealed very little difference between these two groups. With regards to the service criteria found in each service category, our research found marked differences between the service quality priorities of providers and customers in only three of the 18 criteria. However, we found marked differences in service quality priorities in 7 of the 18 criteria when the air cargo service providers were divided into Korean and international air cargo providers. While domestic air cargo service providers evaluated management's capability to handle cargo accidents and incidents as the most important priority, international air cargo service providers placed the highest priority on the cargo rate system. The results of this research imply that in order to properly evaluate the differences between the service quality priorities of air cargo service providers and customers, the air cargo service providers itself should be separated between the Korean air cargo service providers and the foreign providers because of their respective inherent perception on service quality.
