The urban wetland park is an indispensable part of an ecological city. It has aroused widespread attention and even quickly planning and construction around the country. But, in terms of the nature of the urban wetland park, there is a contradiction between the protection of urban wetland resources and the openness of the urban park for public. This article starts with the necessity for construction of urban wetland park, more over expound the existent problems between the protection and openness of the urban wetland park and to propose appropriate measures through the case study on Nanhu National Urban Wetland Park, Tangshan.

This study was conducted to investigate the ambivalent characteristics of dichotomous contradictions expressed by Robert Venturi's architecture. It focused on his Mother's House, which applied his theoretical practices faithfully among many of his architectural works. First, he sought to change interior and exterior spaces by manipulating the architectural scales of "Mother's House". He achieved tension in space through structural complexities in combination with contradictions. Second, as for the characteristics of ambivalent contradictions, including linear and geometric forms, and plane, there were familarity which emphasizes tradition; external appearances of symmetry and asymmetry which give a comfort feeling; openness and closedness, which were expressed with the size of windows and objects such as molding. Third, the fireplace-chimney and the stair were forming appropriate harmony between contradiction and complexity as they competed for central position on the plane.

Cancer treatment remains a serious problem worldwide. Analysis of the relationship between cancer cells and normal cells reveals that these two share characteristics in contradiction, thus could be analyzed by using contradictory principles. Under the theory of contradictory principles, induction of a dormant state or reversal of cancer cells is an important treatment strategy beyond traditional cytotoxic therapy. Normal cells are also the targets and under the influence of anti-cancer treatments and should be considered during therapy. Findings based on crosstalk between these two cell types may offer opportunities for the development of new biomarkers and therapies.

This paper represents a study on the conceptual design of new automatic bicycle transmission. The gear change in a commercial bicycle is carried out by moving the chain between sprockets. By the use of a multiple sprocket for speed change the power loss and transmission shock may occur. To solve the problem of bicycle transmission, the improved solution was derived by the technical contradiction matrix of TRIZ. The conceptual solution is one sprocket which replaces the function of multiple sprockets and adapts actively to the pitch of chain. And it was confirmed to be an adequate design through the Independence Axiom of design axiom.

In recent years, many studies on the public library services for individual vulnerable groups have been performed in Korea. From the standpoint of public libraries with limited human and physical resources, however, all proposed alternatives are difficult to accommodate due to overload and in an integrated perspective, the several alternatives have a logical contradiction and possibility of realistic conflicts. Focusing on these facts, this study proposed an integrated direction and strategic plan to strengthen knowledge and information services of public libraries for five vulnerable classes, ie., the disabled persons, multi-cultural families, the elderly, rural residents, basic living subsidies.

An expert system executes the inference, based on the knowledge of specific domain. the reliability on the results of inference depends upon both the consistency and accuracy of knowledge. This is the reason why expert system requires the facilities which can practice an access to the various kinds of knowledge and maintain the consistency and accuracy of knowledge an maintain the consistency and accuracy of knowledge. This paper is to implement an expert system permitting an access of declarative and procedural knowledge in the knowledge base and in the data base. This paper is also to implement a knowledge acquisition system which adds the knowledge a only if its accuracy and consistency are maintained, after verifying the potential errors such as contradiction, redundancy, circulation, non-reachable rule and non-lined rule. In consequence, the expert system realizes a good access to the various sorts of knowledge and increases the reliability on the results of inference. The knowledge acquisition system contributes tro strengthening man-machine interface that enables users to add the knowledge easily to the knowledge base.

비디오 압축을 위한 움직임 벡터 부호화 과정에서 최적의 예측 움직임 벡터를 율-왜곡 관점에서 선택할 경우, 차분 움직임 벡터의 정보량을 최소로 만들 수 있지만, 추가적으로 예측 움직임 벡터의 인덱스 정보를 부호화해야 한다. 본 논문은 예측 움직임 벡터 인덱스 정보에 대해 모순 검증 기술을 적용하여 전체 예측 움직임 벡터들 중 모순으로 판명된 예측 움직임 벡터를 전체 집합에서 제외시켜 부호화 효율을 증가시키는 기술에 대해서 계층적 B 영상에 대한 새로운 실험한 결과를 제시한다. 제안하는 모순 검증 방법은 Motion Vector Competition 방법과 비교하여 평균 1.26%의 전체 비트량을 절감시킨다.

Construction industry included speciality compare with others industry. Systemically approach and enterprise cultural approach is required in order to perform Knowledge Management in construction industry. But, most of construction enterprise immersed in system approach to perform Knowledge Management, in this reason caused failure of Knowledge Management. To resolve the structural contradiction, Learning organization based the Community of Practice(CoP) is studied in this paper.

Due to the construction technique (or the construction culture) growth in and out of Korea, newly-developed insulation have been continuously released. Furthermore, all legislation and regulation that World follows are gradually becoming unified. (e.g. FTA(Free Trade Agreement) with the United States was contracted, and inevitable FTA contraction with EU and China). In addition, insulation type, with the purpose are becoming unified. Accordingly, KS F 2803 legislated in 1966 about the Domestic Insulation Standard including traditionally used insulation(Rockwool, Fiberglass, Polystrene, Polyurethan, Perlite) has to be amended by considering International Standard and the alternatives. This reference is going to make description for solution of contradiction.
