지방정부 통합은 효율성과 민주성이라는 이념을 지향한다. 하지만 실제 개편에서는 이념적 지향 못지않게 개인적・집단적 이익 추구라는 정치성이 개입한다. 이 논문은 지방정부 통합 논의에서 효율성과 민주성이라는 가치에 대한 다른 해석과 통합 추진의 정치성을 이론적으로 고찰한다. 그리고 선진 몇 개 나라와 우리나라의 통합 과정에서 나타나는 효율성, 민주성, 그리고 정치성의 문제를 분석한 후 우리나라의 지방행정체제개편의 지향성에 대해 고찰한다. The purpose of local government amalgamation (LGA) is often regarded as achieving efficiency and democracy in providing local services. However, politics can not be ignored as a motive for amalgamation. This paper reviews the different connotations of efficiency and democracy in LGA debates and the politics of LGAs. This paper then analyzes the pursuit of efficiency and democracy as well as the influence of politics in recent LGAs in several countries, including Korea. Based on the analysis, this paper evaluates the directions for the current LGA reforms in Korea.

It is essential to implement appropriate sign systems helping way finding and providing guidance to the visitors in a museum or an exhibit center. In particular, for the extensive exhibits where the spaces are configured in discontinuous paths, the visitors find out their own sequences to look around. However, for the irregular exhibitions or island type exhibitions such as event exhibitions, as way finding function is substantially disregarded, the path of action to look around becomes unnecessarily longer, time required to look around cannot be estimated and the path of action in exhibition halls become congested. In order to solve all these problems, it is required to properly install the guidance signs for visitors and accordingly, to provide efficient information to visitors who visit the exhibit centers. However, it requires too much time and costs to support sign systems for the event exhibitions that are frequently changed and remain for a short time. Consequently, this study suggested the sign systems using interactive navigator based on mobile system as an alternative. For the purpose of realizing this possibility, the factors in way findings were extracted and the features of each factor were examined. Moreover, the relationship between each factor was figured out and the results were used to set up basic models.

This paper describes a method for region segmentation and string extractionin documents which are mixed with text, graphic and picture images by the use of the structural characteristic of connceted components. In segmentation of non-text regionas, with connection-characteristic functions which are made by structural characteristic of connected components, segmentation process is progressed. In the string extraction, first we organize basic-unit-region of which vertical and horizontal length are 1/4 of average length of connection components. Second, by merging the basic-unit-regions one other that have smaller values than a given connection intensity threshold. Third, by linking the word blocks with similar block anagles, initial strings are cresed. Finally the whold strings are generated by merging remaining word blocks whose angles are not decided, if their height and prosition are similar to the initial strings. This method can extract strings that are neither horizontal nor of various character sizes. Through computer exteriments with different style documents, we have shown that the feasibility of our method successes.

We introduce the concepts of TL-finite state machines TL-transformation semigroups and coverings and several decompositions of transformation semigroups and investigate some their algebraic structures.
