수요증가 지속과 에너지 산업 구조개편에 따른 발전용 수요의 수급조절역할의 축소로 인해 도시가스 수요 관리에 대한 필요성이 높아지고 있다. 이에 본 연구에서는 도시가스 수료관리를 몇가지 유형으로 분류하고 각 유형별로 가스부문투자(LNG 저장설비소요)에 미치는 영향을 분석할 수 있는 모델을 제시하고 그 검증을 통해 향후 도시가스 수요 관리 시행전략의 수립방향을 제시하고자 한다. 수요관리별 개별효과를 비교하면 동일한 목표율일 경우 최대수요억제가 가장 효과적인 것으로 검증되었으며, 적은 수요물량조정으로 큰 효과를 나타내는 수요관리 유형은 기저부하증대였다. 또한 수요관리전략을 복합하여 시행할 경우, 기저부하증대는 다른 수요관리수단과 같이 실시하여 더 큰 감축효과를 가져왔으나, 전략적 부하창출과 최대수요억제를 동시에 시행하면 그 효과가 상쇄되는 것으로 나타났다. 결론적으로 기저부하증대를 기본으로 하여 전략적 부하창출과 최대수여억제 조치를 시간적인 차이를 두고 시행하는 것이 좀더 효과적일 것으로 검증되었다.

Component-based development(CBD) has been generalized in industry to master the complexity and reduce the development cost and time. However, current CBD practice is developing the component which is dependent on single application[l][2]. Therefore component variability is emphasized to reuse the component in many family members in a domain[8]. However, components are developed for the reason of replaceability rather than the reusability which is the main purpose of the component due to the insufficiency of the study of component variability definition and type[3]. In this paper, we formally specify the component variability reflecting the characteristics of the component to increase the component reusability. We define the logic variability which was recognized as the existing component variability and we propose all types of variability existing in the component by suggesting three more variability types. And we propose the component variability scope which makes us estimate and verify the number of cases of the variability when we customize the component. We propose these component variability types and scope through formal specification. By applying these techniques in developing components, we can develop high quality components reusable in many family members.

It needs theoretical assessment fundamental for informatics curriculum to judge appropriate grades and measure academic standard of an learner according to be included in the conventional curriculum. Thus this study tried to present an criteria on programming area of an informatics curriculum through bloom taxonomy and knowledge type. And it presented assessment criterion on each steps from "Remember" to "Create". And we presented knowledge type examples of programming such as Factual to Metacognitive based on Bloom's knowledge types. Also we analysed that most important level or type is Apply Level, Create Level and Procedural Knowledge. We investigated for each criterion of programming assessment based on bloom's theory through Delphi method. And the result of this investigation was that area of bloom's taxonomy was CVR 0.90, Validity 0.85 and area of knowledge type was CVR 0.90, Validity 0.79. So it can decide to accept for our assessment criteria of programming education based on Bloom theory.

In this study, the six types of menu were suggested according to analysis of elementary school website about informational structure, depth and width of the menu, method of arrangement, suggesting form of the menu, ease the menu usage. And we design and develop the menu, and test, adapting the six types of menu on the same control condition, for the purpose of test about affective response and effectiveness, efficiency in user's utilizing these menus. As a result, the menu type of upper part drop-down type and left part suggesting after upper part suggesting type were testified as a menu type of high approach and recognition in the elementary schools web site.

The purpose of this study was to analyze and evaluate the characteristics of online catalogs' interface of children's libraries, and to propose how to design user-friendly interfaces. The online catalogs of 77 children's libraries which are registered on the National Library Statistics System as of December 2011 were analyzed. They are categorized into 7 types based on interface's characteristics. Such topics as the features of search methods, the record display formats, the terminology usage, and the special features of the 7 types were examined and discussed. Some shortcomings were examined and how to improve them was suggested.

The notes of the classification system are to improve the accuracy and consistency of classification by providing useful information on classification numbers and items. Even though, several notes are used in KDC, they are not enough to keep up with rapidly developing and expanding knowledge of nowadays. The purpose of this study is to suggest appropriate types and improvements of the notes in KDC 5th edition. In order to achieve these purposes, transition of notes in KDC was analyzed. Notes of DDC 23rd edition, NDC new 9th edition, and KDC 5th edition were also analyzed. Based upon these comparison and analysis, problem and improvement of notes in KDC were suggested.

Current mathematics It is necessary to ensure that ratio and proportion concept is not distorted or broken while being treated as if they were easy to teach and learn in school. Therefore, the purpose of this study is to analyze the activities presented in the textbook. Based on prior work, this study reinterpreted the proportional reasoning task from the proportional perspective of Beckmann and Izsak(2015) to the multiplicative structure of Vergnaud(1996) in four ways. This compared how they interpreted the multiplicative structure and relationships between two measurement spaces of ratio and rate units and proportional expression and proportional distribution units presented in the revised textbooks of 2007, 2009, and 2015 curriculum. First, the study found that the proportional reasoning task presented in the ratio and rate section varied by increasing both the ratio structure type and the proportional reasoning activity during the 2009 curriculum, but simplified the content by decreasing both the percentage structure type and the proportional reasoning activity. In addition, during the 2015 curriculum, the content was simplified by decreasing both the type of multiplicative structure of ratio and rate and the type of proportional reasoning, but both the type of multiplicative structure of percentage and the content varied. Second, the study found that, the proportional reasoning task presented in the proportional expression and proportional distribute sections was similar to the previous one, as both the type of multiplicative structure and the type of proportional reasoning strategy increased during the 2009 curriculum. In addition, during the 2015 curriculum, both the type of multiplicative structure and the activity of proportional reasoning increased, but the proportional distribution were similar to the previous one as there was no significant change in the type of multiplicative structure and proportional reasoning. Therefore, teachers need to make efforts to analyze the multiplicative structure and proportional reasoning strategies of the activities presented in the textbook and reconstruct them according to the concepts to teach them so that students can experience proportional reasoning in various situations.

This paper suggests facility planning ideas for recreational fishing complexes suitable for family anglers. Existing recreational fishing parks are only equipped with facilities for angling. There are many needs for recreational fishing complexes in coastal fishing villages that include not only angling facilities but also various marine leisure and sports facilities. In this paper we suggest concepts for recreational fishing complexes and define four types of complexes in terms of facilities planning. These four types of complexes are: 1) suburban leisure sports, 2) suburban healing and relaxation, 3) penturban experience and activities, and 4) penturban culture and recreation. Then we propose facility composition in detail for each type. Also we suggest site selection criteria for the village complex, facility infrastructure planning ideas, and leisure facilities (elementary and specialized) for recreational fishing complexes.

Recent studies of multiple participatory interactive media designs hows that the key element to this area is the participation of the audience. Due to this matter, this paper discusses the categories of the phase and looks into the characteristics of participatory matters to clarify the distinction. The categories that has been mentioned in this paper are multiple participatory types and active participatory types. Based on this matter, research practicing the Mira has been conducted in two separate groups - video and sound, and suggests the solution to the problems that has occurred during the process of implementing the final video system called 'The 360 Project'. The fact that the paper suggests a small range of participatory categories and hasn't come up with a certain analysis to the final outcome appears as a limit. The inadequacy will be supplemented throughout the following paper, hoping there will be improved versions of multiple participatory researches.
