In this paper we present INCUI, a user interface based on natural view of physical user interface of target devices and services in pervasive computing environment. We present a concept of Intuitively Natural and Consistent User Interface (INCUI) consisted of an image of physical user interface and a description XML file. Then we elaborate how INCUI template can be used to consistently map user interface components structurally and visually. We describe the process of INCUI mapping and a novel mapping method selection architecture based on domain size, types of source and target INCUI. Especially we developed and applied an extended LCS-based algorithm using prefix/postfix/synonym for similarity calculation.

2D 평면상에 이미지를 매핑 하는 것은 디자인 프로세스의 초기에 디자인 트랜드를 이해하는 방법의 하나로써 자주 이용되어 왔다. 이러한 유형의 분석 방법은 로봇 디자인 과정에도 필요하다. 본 연구는 로봇 디자인 분석을 위한 보다 진보된 방법으로써의 인터랙티브 맵의 개발과 활용에 초점을 맞추고 있다. 우선 매핑을 위한 기초 자료로써 로봇 디자인 샘플들을 대상으로 휴리스틱 평가와 사용자 설문조사가 실시하였다. 그 결과는 선형 스케일로 변환되었으며 이를 기초로 매크로미디어사의 플래시를 이용한 인터랙티브 매핑 툴이 개발되었다. 본 연구에서 개발된 인터랙티브 맵은 로봇 디자인의 객관적인 특성을 나타내는 6가지 키워드와 사용자의 유형에 따른 9가지 주관적인 선호도로부터 추출되는 2개의 요소들로 구성되는 105가지 맵을 제시할 수 있다. 디자이너가 2가지 다른 요소들을 자유롭게 선택함에 따라 선택된 2가지 요소를 축으로 하는 이미지 맵이 자동적으로 구성되어 제시된다. 본 연구에서는 이와 같은 인터랙티브 맵을 이용해 실제 사례연구를 진행함으로써 디자이너들이 보다 다양한 발견점과 직관적인 통찰력을 얻을 수 있음을 제시하였다. 이러한 방법은 기존의 전통적인 직접적인 2D 매핑과 비교해서 보다 객관적이고 효율적인 방법으로 생각된다.

온톨로지 매핑은 서로 다른 온톨로지에 있는 클래스가 유사한 개념을 표현한 것인지 판단하는 문제이다. 클래스 유사도를 계산 하는 방법에는 클래스의 이름 어휘 유사도, 의미 유사도, 클래스 관계/속성 유사도 그리고 클래스 상하위 관계 유사도 등이 제안되었다. 본 논문에서는 이러한 클래스 유사도를 계산하기 위한 반복적 유사도 계산 알고리즘을 제안한다. 매 반복 단계마다 모든 클래스 쌍의 유사도를 전부 갱신 하는 방법과 유사도가 최대인 쌍만 선택적으로 갱신 하는 방법을 비교 실험하였다. 실험 결과 유사도가 최대인 쌍만 업데이트하는 방법의 성능이 좋았고 소요시간도 적었다.

Based on SPICE (Software Process Improvement and Capability dEtermination) evaluation model, SPIRE (Software Process Improvement in Regions of Europe) is developed and published as a process improvement model for small and medium size organizations. However, practical selection guidelines or mapping rules between business goals and software processes do not exist within SPIRE. This research aims to construct an objective reference mapping table between business goals and software processes, and to propose a process selection method using the mapping table. The mapping table is constructed by the convergence of domestic software process experts' opinions using Delphi techniques. In the suggested process selection method, target processes are selected using the intuition of project participants or project managers as well as the reference mapping table. The feasibility of the proposed selection method has been reviewed by applying to two small software companies. Using the reference mapping table, we could select key processes which were passed over by project managers.

Currently lots of studies to solve meta-data interoperability in between schema attributes are conducted. But the accuracy in previous schema mapping studies is low since the studies just use the similarity in between attributes. So the studies are not suitable for the schema mapping such as document conversion, system integration, etc. In this paper, we propose a method which can conduct the schema mapping interactively using frequent pattern mining. The method can conduct more accurate mapping process because the method use the description element which is an element among each schema element for the metadata standard. A performance study has been conducted to compare the accuracy performance of the method using metadata standards.

This paper is related to an Object VR-based virtual textile wearing system carrying out textile texture mapping based on viewpoint vector estimation and intensity difference map. The proposed system is characterized as capable of virtually wearing a new textile pattern selected by the user to the clothing shape section segmented from multi-view 2D images of clothes model for Object VR(Object Virtual Reality), and three-dimensionally viewing its virtual wearing appearance at multi-view points of the object. Regardless of color or intensity of model clothes, the proposed system is possible to virtually change the textile pattern with holding the properties of the selected clothing shape section, and also to quickly and easily simulate, compare, and select multiple textile pattern combinations for individual styles or entire outfits. The proposed system can provide higher practicality and easy-to-use interface, as it makes real-time processing possible in various digital environment, and creates comparatively natural and realistic virtual wearing styles, and also makes semi-automatic processing possible to reduce the manual works.

In this paper, CPLD low power technology mapping using reuse module selection under the time constraint is proposed. Traditional high-level synthesis do not allow reuse of complex, realistic datapath component during the task of scheduling. On the other hand, the proposed algorithm is able to approach a productivity of the design the low power to reuse which given a library of user-defined datapath component and to share of resource sharing on the switching activity in a shared resource Also, we are obtainable the optimal the scheduling result in experimental results of our using chaining and multi-cycling in the scheduling techniques. Low power circuit make using CPLD technology mapping algorithm for selection reuse module by scheduling.

The Organizations working with technological projects will be more and more common to connect consultants. Those who shall carry out the pre-analysis of the projects ought to have a professional knowledge to the area about economical methods with information technology and changed technology of surveying and mapping. New surveying and mapping methods, such as TotalStation, GPS, orthophoto, digital map, and satellite remote sensing, have totally changed the old concept of surveying. Also the technology for the new mapping has greatly changed from analog to analytical to digital during the past 50 years. Now, the proper choice of surveying and mapping methods becomes a decision on cost and efficiency rather than the use of a particular technology. As an example, GPS equipment dose cost considerably more than traditional surveying equipment, but the advantages it provides make it very cost-effective. In this study, the cost and benefit factors of the surveying and mapping projects are evaluated independently and benefit/cost ratio(B/C ratio) is used in benefit-cost evaluation of the different surveying methods. The benefit-cost model of surveying and mapping methods will produce economical result in the whole projects.

This paper proposes a novel FTL (Flash Translation Layer) algorithm based on sector-level mapping to reduce the number of total erase operations in flash memory accesses. The proposed algorithm can reduce the number of erase operations by utilizing the sector-level mapping table when writing data at flash memory. Sector-level mapping technique reduces flash memory access time and extendsthe life time of the flash memory. In the algorithm, wear-leveling is implemented by selecting victim blocks having the minimal number of erase operations, when empty spaces for write are not available. To evaluate the performance of the proposed FTL algorithm, experiments were performed on several applications, such as MP3 players, MPEG players, web browsers and document editors. The proposed algorithm reduces the number of erase operations by 72.4% and 61.9%, when compared with well-known BAST and FAST algorithms, respectively.
