This study is about the efficiency of graph theory that can be applied as the research analysis method in order to identify the relational location features of the caves favored as the ecological tourists attraction. Creating network with traffic nodes and surrounding tourists attractions in a certain space including the caves as the tourists attraction and structural analysis on the overall network using various kinds of index will be very useful method to identify the relational location features and benefits from linking the caves as the tourists attractions. In particular, it can be applied to set the spatial scope in the tourism development plan including the caves as the tourists attractions.

본 연구는 국내 농촌지도인력 역량모델 개발을 위한 기초 연구로서 역량의 정의, 역량모델 개발방법, 인적자원개발을 위한 역량모델 활용 현황에 대한 문헌을 고찰하였다. 역량은 사용되는 상황이나 맥락에 따라서 다양하게 정의되고 있어 사전적인정의와 다양한 연구자들의 역량의 정의에 대한 이론, 특정한 조직이나 직업군에서 사용되고 있는 역량의 정의를 비교 분석하였으며, 결과적으로 역량은 개인의 역할 수행과 직무성과와 상관관계가 있으며 훈련과 개발을 통하여 개선되어질 수 있는 관련된 지식, 기술, 태도의 집합체로 정의하였다. 역량모델을 개발하는 방법도 다양한데, 초기단계에서는 탁월한 직원과 일반직원의 특정한 업무추진사례를 인터뷰와 관찰을 통하여 분석하여 이들 간에 차이를 가져오는 특성이나 행동을 추출하는 직무역량진단법이 주로 활용되었다. 이 방법에는 많은 비용과 시간이 소모되어 이를 간소화한 여러 가지 방법이 개발되었다. 또한 기존 직원 특성 분석보다 다양한 정보원과 미래에 대한 가정을 활용하여 바람직한 직무 결과와 역량, 역할을 추출하는 방법도 개발되었으며 직업이 빠르게 변화하는 시대적인 특성상 이런 방법의 활용이 확대되고 있다. 이런 다양한 방법 중 역량 모델을 활용할 직무나 조직의 특성에 맞는 방법을 선택하여 적용하여야 한다. 역량모델을 활용한 인적자원개발을 통하여 기업뿐만 아니라 정부조직에서도 효율적인 직원 역량 개발, 개인과 조직의 성과 향상 등의 효과가 나타나고 있으며, 앞으로 농촌지도조직에서도 지도인력 역량 개발과 지도사업의 효율성을 향상을 위하여 역량모델을 개발 활용할 필요성이 있다.

This thesis is focused on online education and proposes a guideline for selecting teaming theories and multimedia representation without difficulty. On the first, consideration of learning theories and analysis of multimedia properties are made, and from these results guidelines are formed. Then they are applied to each 6 types of CAI. Objectivism and constructivism could be used for the basic framework of CAI. The former is suitable for reed, sequential, structural, and passive learning style and the latter is suitable for selectable, unstructural, active, self-controled, learning style. And the quideline for selecting multimedia representation is made out of the properties of media, learners(cognitive model, proficiency, acceptance), and teaming contents. On the basis of guideline obtaining from the previous process, I suggest mosts suitable conditions for each 6 types of CAI available today. Those conditions are consist of learning theories, media selection, levels of learners, and categories and properties of teaming contents.

점성토의 압밀거동은 투수성뿐만 아니라 변형 특성에 따라 크게 영향을 받으며, 변형 특성은 재하 방법에 따른 변형조건과 흙의 특성, 특히 이방성에 따라 다르게 나타난다. 이 논문에서는 점성토의 이방적 변형 특성이 압밀거동에 미치는 영향을 분석하기 위하여 다양한 변형 조건에 대한 압밀방정식과 압밀계수를 직교 이방성 탄성이론을 이용하여 유도하였다. 다양한 변형 조건에서 등방과 이방적 변형 특성하의 압밀계수를 평가하였으며, 그 결과 탄성계수의 이방성이 압밀계수에 미치는 영향이 매우 크고, 특히 수평방향의 변위가 허용되고, 수직방향의 변위가 구속될수록 크게 나타났다. 따라서 점성토 지반에 대한 하중 재하시 압밀소요시간의 정확한 예측을 위해서는 발생 가능한 변형 조건과 이방적 변형 특성에 대한 적절한 고려가 매우 중요함을 알 수 있었다.

As interdependence and conflict are important to the understanding of channel interactions, many researchers have studied their relationship. Identifying the relationship between interdependence and conflict will help understanding an exchange relationship. In social science, the relationship between interdependence and conflict is explained by two contradictory theories, and there are also inconsistent results in marketing science. The authors suggest non-linear relations between asymmetric interdependence and conflict, based on bilateral deterrence theory and conflict spiral theory. Using survey data from industrial market, we demonstrate that there is an inverted U-shaped relationship between asymmetric interdependence and interfirm conflict. The result show, as the magnitude of interdependence is high. the hypothesis on the non-linear relationship between asymmetric interdependence and conflicts is acceptable on both suppliers and distributors. Finally, we discuss several theoretical implications and suggest limitations and future research issues.

There exist two major difficulties in developing flight control system: nonlinear dynamic characteristics and time-varying properties of parameters of aircraft. Instead of the difficulties, many high reliable and efficient control methodologies have been developed. But, most of the developed control systems are based on the exact mathematical modelling of aircraft and, in the absence of such a model, it is very difficult to derive performance, robustness and nominal stability. From these aspects, recently, some approaches to utilizing the intelligent control theories such as fuzzy logic control, neural network and genetic algorithm have appeared. In this paper, one advanced intelligent lateral control system of a high speed fight has been developed utilizing type-2 fuzzy logic, which can deduce the uncertainty problem of the conventional fuzzy logic. The results will be verified through computer simulation.

The reflection and transmission of submerged breakwater with trapezoidal type are computed numerically using boundary element method. The analysis method is based on the wave pressure function with the contlnuit? in the analytical region including fluid and porous structures. Wane motion within the porous structures is simulated by introducing the linear dissipation coefficient and added mass coefficient. The results indicate that transmission and reflection coefficient are determined due to the change of slope of submerged breakwater with trapezoidal type.

During the landscape design process, landscape architects produce various forms of drawings to visualize the future designed landscape. This work thoroughly examines the process of the utilization of James Corner's theory and practice of representation. Since the early 1990s, Corner has explored the characteristics and functions of landscape architectural drawing theoretically. Specifically, Corner argued that the use of visual representation makes it difficult to achieve the full embodiment of all of the multisensory characteristics of a landscape. Thus, he explored new drawing techniques that alternatively visualize the landscape and generate creative ideas(i.e., imagination of drawing), rather than a realistic illustration of not-yet-actualized landscapes(i.e., instrumentality of drawing). Corner's theory has evolved throughout the mid and late-1990s as applied to landscape practice. Corner embraced ecology and implemented the theory and practice of Landscape Urbanism, thereby once again emphasizing the instrumentality of drawing. Whereas the early theory mainly explored a perspective view using collage and montage, Corner later began to stress the importance of the instrumentality again. For example, Corner employed a mapping technique based on the instrumental map and that simultaneously creatively transforms it. Corner's theory and practice of representation fully explored the identity of landscape architectural drawings and reflected the interaction between theory and practice. Thus, his design and theoretical works continue to have significant influence on present landscape practice and theory.

The purposes of the study are to recognize importance of motivation in math education and to increase interest in students' motivation problem by comparing math motivation between mathematically gifted and non-gifted 5th graders based on Keller's ARCS theory and analyzing correlations between math motivation, mathematically affective characteristics and mathematical achievements. For this purpose, 436 students who were mathematically gifted and non-gifted 5th grade students were asked to take questionnaires and test to measure math motivation, mathematically affective characteristics and mathematical achievements. After analyzing the data, there are statistically differences in three educational factors between two groups. In addition, there are correlations between three educational factors. This study revealed that highly motivated students showed positive mathematically affective characteristics and high mathematical achievements. As results indicate that motivation could be a crucial factor in learning, teachers should consider motivation strategy to plan students' lessons regarding to learners' giftedness.
