주간선도로의 ITS 사업 등 동적정보의 제공이 최근 도로이용자에게 제공되고 있으나, 지방부의 정적인 정보를 제공하는 도로표지는 아직도 안내기능이 취약한 것이 사실이다. 지방부 도로를 대표하는 지방도는 연장에 있어서 모든 도로를 통해서 최장이며 고속국도, 국도, 국가지원지방도와 함께 복잡한 도로망을 형성하고 있다. 즉, 도로의 대종을 차지하는 지방도는 아직도 정적정보제공기반도 취약하다는 것이며, 증가하는 수요에도 불구하고 길 찾기의 기능이 가장 미흡한 도로가 지방도이다. 이러한 지방도의 경우 같은 위계의 지방도 간에도 노선연장 및 지역적 차이가 크며, 노선의 연속성 또한 미약하다. 이러한 지방도 도로안내체계의 문제를 해결하기 위해 본 연구에서는 노선별 적절한 안내지명을 선정하고, 선정된 지명을 통해 도로안내 및 표지간의 연계성을 유지하기 위한 도로표지시스템을 개발하는 것이 목적이다. 이동에 있어 중추적 기능을 수행하는 도로가 아닌 지방도는 장거리 통행을 위한 위계 높은 도로와의 연계가 필수적인 만큼 본 연구에서는 도로표지규칙의 지방도 안내지명 선정에 대한 선정원칙을 재검토하고, 지방도의 적절한 안내지명 선정을 위해서 타 노선과의 연계유형을 분석하였다. 분석결과 9가지의 유형을 도출하였고, 도출된 노선연계 유형을 기반으로 노선별 거점을 선택하는 것으로 하였다. 한편, 안내지명에 대한 설문을 실시하였고, 그 결과 각 노선별 거점을 중요지와 주요지로 구분하여 정의, 선정하여 안내를 위한 기본 틀을 제시하였다. 제시된 안내지명서정요령 및 틀을 통해 지방도내의 및 지방도와 기타도로와의 연계성이 더욱 고조되고, 안내체계의 효율성의 증대가 기대된다.

This paper related to implementing issue and performance measuring about blended mechanism between networking technology and security technology. We got more effectiveness in overall network security, when applying and composing amalgamated security mechanism between network technology and security technology. The blended method offers $8{\sim}10%$ effective result in network security than the isolated ways of applying relational two technologies. As a result, we suggest amalgamated security mechanism between network technology and security technology, and also, we propose the blended method as a model of more effective way.

This study aims to analyze the continuity and sequence between the intelligent life curriculum for grades 1-2 and the science curriculum for grades 3-4 with a focus on knowledge and inquiry process skills. The results demonstrate that contents related to science in the intelligent life curriculum consisted of only 10 out of 32 elements. Five elements were related to the science curriculum for grades 3-4 and limited to the 'life sciences' area. Particularly, the intelligent life curriculum did not address topics related to 'matter' and 'motion and energy'. Developmental connection was established in the 'life sciences' area and dramatic changes were noted for the topics related to 'earth and space' area. In terms of inquiry process skills, the levels of observation, measurement, inference, and communication naturally increased, whereas a developmental connection was noted between the intelligent life and science curricula. Classification can be viewed as a developmental link; however, viewing the classification as scientific from the epistemic perspectives was insufficient. In the case of expectation, a gap was observed in both curricula due to the absence of expectation activities in the intelligent life curricula. The study discussed the implications for securing the connection between the intelligent life and science curricula on the basis of these results.

Design value engineering (VE) has been performed in many construction projects according to the changes in the construction for most of the VB function analysis that performed, are problems that focus on function analysis and generating ideas based on individual experience of VE team member than generating ideas and value improvement of systematic function analysis. This may be due to the quotation of previously performed function analysis data, general function analysis, and abstract function definitions that do not cite the concrete characteristics of each facility. Therefore, in this study, the proposed cases from the existing design VE workshops, the current conditions of the connection between functions and ideas and of the idea categorization by building part were studied to determine why functions and ideas are not connected, and to propose pertinent improvement directions. on a performance-based function categorization system by building part that can provide the logical connection between functions and ideas in the function definition/categorization and function arrangement phases in the function analysis phase, the most important phase in VE activities, was developed by reflecting the required performance and functions for each part of the facility.

Function analysis and idea creation phase in Value Engineering(VE) Process is applied to manufacturing Industry for developing functions for elements of products, and in construction come to use various components like process, size of project, spaces as well as function itself due to multi-functional aspect. For this reason, VE applications to the construction industry are considered to be less frequent and efficient than to the manufacturing. To resolve this problem, a new technique of Function Integration Fast(HI FAST) and Hierarchical Value Engineering Concept Modules(HVECM) was made for practical integration and sequence of VE job Plan. Two types of function would be defined In this method, first and second function, during the job Plan process, and two function champions be selected for next creation phase process. For verification of consecutiveness of function analysis and idea creation phase for successful VE project implementation, this methodology was tested under design phase in office and IT Multi-functional building project. Make sure the successful application of this process with this method, need to develop the talent of VE experts and team members for process of function analysis and creation phase.

One of the most important objectives in science education is to develop students' science literacy. The purpose of this study is to analyze the relevance between biology instructional objectives in the 7th curriculum taught in elementary and secondary schools. For this study, 7 major parts in each grade were analyzed including cell, the form and function of plants, the form and function of animals, genetics, diversity, evolution, ecology, and environment. The strand map of instructional objectives is completed that represents the relation between the objectives. The summary of the results from this study is as follows. First, the concept about cells is not fully covered in lower grades including elementary schools. While the concept of energy metabolism is repeatedly covered, there is no concept of energy covered in learning the concept of energy metabolism in elementary schools. Second, the textbooks in elementary and middle schools have main concepts about the form and function of plants while those in high schools don't. The concept related to the part of the form and function of animals is repeatedly involved in the curriculum throughout the elementary, middle, and high schools. Third, the concepts such as genetics and evolution are involved in higher grades since these concepts are abstract ones. The part of genetics and evolution as well as diversity has no connection between grades in schools, so the development of "notion between" is necessary to relate these concepts with each other. Fourth, the 4 parts of diversity, ecology and environment, evolution, and the form and function of plants are covered in limited grade levels. The results of the relevance of gene in lesson goals will play an important rein as the primary material in developing the connection between textbooks in which lesson goals are closely related to each other throughout all grade levels in elementary, middle and high schools.

Recently, the building of an intermodal transportation system has become the most important policy in the establishment of a national-wide sustainable transport system. In the case of rail and public transport, an intermodal connecting improvement policy is essential due to the lack of trip completeness. In particular, high-speed rail has brought dramatic changes to the transportation system in Korea and the idea of high-speed rail stations as major transportation nodes to be linked to various travel modes needs to be analyzed in terms of an intermodal network. Thus, this study proposes a new connectivity analysis method to objectively and quantitatively evaluate intermodal connecting performance for high-speed rail in terms of an intermodal network around high-speed rail stations. Seoul, Busan, Ulsan, and Sin-gyeongju stations were designated for a range of spatial analyses; detailed connecting performance indexes of travel modes connecting high-speed rail stations, and the influence sphere of these stations are analyzed, except for internal transfer facilities. Finally, this study proposes a connectivity analysis method that applies the structural equation model and develops a connectivity index.
