워터쉐드 알고리즘에 의해 과분할 된 영상은 이후 영상의 이해 및 분석 작업의 편의성을 위하여 영역 병합 작업이 필요하다. 본 논문에서는 유사한 색상을 갖는 영역의 경계선을 보다 잘 유지할 수 있도록 통합 비유사도를 정의하고, 이를 이용한 영역 병합 방법을 제안한다. 통합 비유사도는 영역의 색상 정보, 인접한 두 영역 사이의 평균 그래디언트 값 정보, 두 영역 사이의 인접한 픽셀 수 정보를 이용하여 정의된다. 영역 병합과정에서는 영역 면적의 크기와 영역간 통합 비유사도를 고려한 3 단계 영역 병합 방법을 수행한다. 자연 영상에 대한 실험 결과 제안한 방법이 기존의 방법보다 경계선 정보를 보다 잘 유지하고 사람이 느끼기에 보다 정확한 영역 병합 결과를 나타냄을 확인하였다.

This reserch is to compare and analyze of the residence disposition and feature of ground plan on Seomi 2 Dong in An-dong and Hyun-ri in Mun-gyong. The scope of this reserch concentrated on 33-housed which are 12-housed in Seomi 2 Dong and 21-housed in Hyun-ri. The focus of this reserch is mainly to investigate the characteristic of the site, and ground plans on individual houses. As result of it, there are mostly Yeo-Kan houses (six spans sized) on Seomi 2-dong village in An-Dong on the other hand there are a lot of Straight-Houses in Hyun-ri in Mun-gyong. Otherwise in characteristic of residence, There is dissimilarity between Seomi 2-dong which located in mountainous districts has space organization of utilitarian and Hyun-Ri has justification primacy as a farm village.

During a sampling at Nokdong harbor, southern coast of Korea in January 2017, the marine diatom Coscinodiscus wailesii cells infected by a novel parasitoid nanoflagellate were observed. While the development process of the trophosomes of the parasitoid was more similar to that of Pseudopirsonia mucosa, division pattern of the auxosomes was similar to that of Pirsonia species. Phylogenetic analyses inferred from 18S rRNA gene sequences revealed that the parasitoid infecting C. wailesii fell within the cercozoan groups and branched as a sister lineage of the clade consisting of Pseudopirsonia mucosa and the undescribed Cercomonas sp. SIC7235, with the sequence dissimilarity of 7.3% with Pseudopirsonia mucosa. All of these developmental and molecular characteristics suggest that the parasitoid nanoflagellate infecting the diatom C. wailesii is a new Pseudopirsonia species.

The purpose of this study is to design effective working systems which adapt to change in human needs by developing an method which forms into optimal groups using the measure of cohesion. Two main results can be derived from the study as follows : First, the clustering method based on the entropic measure of cohesion is predominant with respect to any other methods proposed in designing the work groups, since this clustering criterion includes symmetrical relations of total work groups and the dissimilarity as well as the similarity relations of predicate value, the clustering method based on this criterion is suitable for designing the new work structure. Second, total work group is clustered as the workers who have the equal predicate value and then clustering results are produced through the combinatorial agglomerative hierarchical clustering method. This clustering method present more economic results than the method that clustering the total work group do.

Strategic aim of Poland is an accession to The European Union. This accession means consolidation of democratic transformations and acceleration of economical development. Possibly full and quick execution of preparing works at building domain is one of conditions of Polish membership in the European Union. Poland has to adopt rules and standards, which are required at EU. It will permit to make polish companies more attactive at international market. We should know, that economical, legal whether political reforms, this is not all what consists on membership at the Union European. We must change internally, become open to the world, to represent dynamism, enterprise, knowledge and culture. We must become more tolerant and be able to communicate with people with different culture whether political orientation, we have to accept this dissimilarity and will find way of dialogue and cooperation.

The conventional clustering approaches are mostly based on minimizing total dissimilarity of input and output. However, the clustering approach may not be helpful in some cases of clustering decision making units (DMUs) with production feature converting multiple inputs into multiple outputs because it does not care converting functions. Data envelopment analysis (DEA) has been widely applied for efficiency estimation of such DMUs since it has non-parametric characteristics. We propose a new clustering method to identify groups of DMUs that are similar in terms of their input-output profiles. A real world example is given to explain the use and effectiveness of the proposed method. And we calculate similarity value between its result and the result of a conventional clustering method applied to the example. After the efficiency value was added to input of K-means algorithm, we calculate new similarity value and compare it with the previous one.

There is world wide concern for safety of nuclear power installations after the terrorist attack on World Trade Center in 2001 and several other civilian structures in the last decade. The nuclear containment structure in many countries is a double shell structure (outer shell a RCC and inner a prestressed concrete). The outer reinforced concrete shell protects the inner shell and is designed for external loading like impact and blast. A comparative study of non-linear response of reinforced concrete nuclear containment cylindrical shell subjected to impact of an aircraft (Phantom) and explosion of different amounts of blast charges have been presented here. A material model which takes into account the strain rate sensitivity in dynamic loading situations, plastic and visco-plastic behavior in three dimensional stress state and cracking in tension has been developed earlier and implemented into a finite element code which has been validated with published literature. The analysis has been made using the developed software. Significant conclusions have been drawn for dissimilarity in response (deflections, stresses, cracks etc.) of the shell for impact and blast loading.

The purpose of this paper is to analyze the efficiency change and its determinants of the regional public hospitals. We utilize 34 regional public hospital's panel data for 6 years from 2003 to 2008. We use DEA(Data Envelopment Analysis)-CCR, BCC model, DEA/Window model, and DEA Profiling. The empirical results show the following findings. First, technical efficiency shows that approximately 3.6% of inefficiency exists on the regional public hospitals and it reveals that the cause for technical inefficiency is due to scale inefficiency. Second, DEA/Window results show that the stable dissimilarity by standard deviation, LDP of CCR. Third, the results of partial efficiency by DEA Profiling show that increase efficiency depends on the number of beds, doctors, and nurses.

In this paper, data-driven modeling and multiresolution analysis (MRA) are applied for a full-scale wastewater treatment plant (WWTP). The proposed method is based on modeling by partial least squares (PLS) and multiscale monitoring by a generic dissimilarity measure (GDM), which is suitable for nonstationary and non-normal process monitoring such as a biological process. Case study in an industrial plant showed that the PLS model could give good modeling performance and analyze the dynamics of a complex plant and MRA was useful to detect and isolate various faults due to its multiscale nature. The proposed method enables us to show the underlying phenomena as well as to filter out unwanted and disturbing phenomena.

Two existing continuous-time models for the current-mode control have presented noticeable differences in their small-signal predictions. As an attempt to clarify the origin of these disparities, this paper presents an alternative way of deriving a continuous-time model for the current-model control. The results of this paper would provide insights to comprehend the dissimilarity in the modeling method and final results of the earlier models of current-mode control.
