본 논문에서는 세계적으로 널리 사용되어지고 있는 초고층 건축물의 진동사용성 평가기준이 검토되었다. 초고층 건축물의 진동에 대한 사용성 평가기준은 바람에 의한 초고층 건축물의 가속도 응답의 크기로 나타내는 것이 일반적이다. 건축물의 가속도의 응답의 크기를 산정함에 있어서 두 가지의 서로 다 른 척도, 즉 최대가속도 또는 RMS가속도를 각 기준에서 채택하고 있는데 이에 대한 상이점을 토의하고 각 국의 진동사용성 평가기준을 고찰함으로써 우리나라에는 어떤 진동사용성 평가기준이 적합한가에 대한 논의를 시작하고자 하였다. 그리고 건축물의 각기 다른 응답을 조사하여 최대가속도와 RMS가속도와 관계를 면밀히 검토하고 각각에 대해 기술적인 논거를 기술하였다.

본 연구에서는 국내 원전에서 기기 정착을 위하여 가장 널리 적용되는 직매형 앵커기초를 대상으로 앵커기초의 인장 설계기준에 대한 적정성을 검토하기 위하여 수치해석이 수행되었다. 본 연구에서 수치해석모형에 적용된 파괴기준으로서 콘크리트와 같은 유사 취성재료에는 Microplane모형이, 앵커볼트와 같은 연성재료에는 탄성-완전 소성모형이 적용되었다. 그리고, 균열 발생현상을 모사하기 위하여 분산균열모형을 채택하였다. 개발된 수치해석모형은 다양한 경우의 실증시험결과를 근거로 신뢰성이 검증되었으며, 검증된 수치해석모형과 앵커볼트의 유효매입깊이를 변수로 한 다양한 경우에 대한 수치해석을 통하여 직매형 앵커기초의 인장설계기준으로서 적용이 가능한 ACI 349 Code와 CEB-FIP Code가 평가되었고, 그 보수성이 확인되었다.

The purpose of this article is to delve into the problems of originality of the artwork by examining issues of reproduction within the contemporary art market. In contemporary arts, especially in terms of art production and consumption, we can’t overlook society and its economic structure and its connection with of capitalism. As the purity of art creation has turned into an exchange value, art, especially an object as artwork, has fallen into the status of production in an economic marketing system. Walter Benjamin mainly referred to that point in his thesis Das Kunstwerk im Zeitalter seiner technischen Reproduzierbarkeit, which originated the sociology of plastic arts. This thesis, published in 1936, traced how the artistic functions of photograph and movie had been changed through the social development. His main concerns were movie and photograph but what I am concentrating from his point of view, is that even in the field of plastic arts, the manufacture of reproduction has been practiced as a primary method within the social and political contexts and development. Though I am referring to this in the main body of this article, reproduction in contemporary art strongly needs a new definition since it has been spread all over like a newest virus, not only by collector’s personal taste or but also by commercial circulations of these reproductions to the public. This relates to Benjamin’s argument about the value of an exhibition at a museum(Ausstellungswert). Since the function of an artwork has been one of cultural industry, the manufacturing of reproduction raises unexpected problems, such as, the originality of the artwork, the value of an exhibition at a museum, its achievement as documentary and as a territory of art criticism. In this point of view, I want to inquire into the value and criteria of an exhibition in contemporary art through the review of the definitions and the intrinsic attributes of reproduction. Somehow in a broad sense, the reproduction is a product coming out of representation or copy (replica) of an original art work or an model. Therefore, the problems it presents differ from the Simulacre, which is an image without an original one. In terms of the Meanings of reproduction, we can distinguish it as reproductions, copies, and productions. These types of reproductions are not the original artworks reflected by the creative intention of the artists. For example, a publishing company reproduced some of lithographs of Salvador Dali in the 1960s. They are commercial copies in the form of representation or reproduction with no artistic and creative intention of the artist. However, In despite of this theoretical basis, reproductions of the famous artists are still displayed without any verification for of the public’s quest for the artworks. Moreover, many commercial companies that are planning to exhibit art works of the world-famous artists only for their profits keep trying to speak ill of and judging by the law the honest art critics’ articles which discuss the true values of exhibition. If freedom of expression is one of the ideals of democracy, even the judgment of the originality of the artworks should be freely expressed.

Finding an optimal solution in MADM(Multi-Attribute Decision-Making) problems is difficult, when the number of alternatives, or that of attributes is relatively large. Most of the existing mathematical approaches arrive at a final solution on the basis of many unrealistic assumptions, without reflecting the decision-maker's preference structure exactly. In this paper we suggest a model that helps us find a group consensus without assessing these parameters in specific cardinal values. Therefore, This research provides a comprehensive Decision Making of the theory and methods applicable to the analysis of decisions that involve risk and multiple criteria attributes. after, The emphasis of the procedure will be on developments from the fields of decisions analysis and utility theory of Taguchi Method. This theoretical development will be illustrated through the discussion of several real-world application and a case study. When the multiple number of decision makers are involved in the decision making procedure, the problem of uncertainties invariably occurs, because of the different views between them. In this paper, New decision making model using Taguchi Method is applied to effectively model the multi-attribute-decision making(MADM) procedure in the uncertainties dominated two area(quantitative and qualitative factors), Quantitative factors evaluation is used Loss Function of Taguchi, qualitative factors evaluation is used S₩N ratio by each specialist. thus it can be used for aiding of preferable alternative. as a result, We will be proved efficiency about New decision making model of applied Taguchi Method with Analytical presentation of all the expecting outcomes when a specific strategy or an alternative plan is selected under expecting future environment.

Recently, Avatar business has in favor on the internet and lots of profit has been increasing. In this study, we apply evaluation criteria for clothing purchase to Avatar, and try to find out the differences of the evaluation criteria by the age and sex.

This study was conducted to determine the daily application rate and amount of N and K with fertigation during different growth stages in semi-forcing culture of cucumber plants (Cucumis sativus L. cv. Eunseongbaekdadagi). The diagnostic criteria for N and K also investigated based on petiole sap analysis. The dry weight increased slowly until 30 days after transplanting. The highest dry weights were observed at 60 days after planting, then it decreased. As the plant grew, the contents of N and K in the petiole sap and fruit of cucumber decreased. The daily uptake of N and K were highly correlated with the growing days. The NO3 concentrations in petiole sap were in the range from 3,500 to 4,500 mgㆍL-1 in the early growth stage, but those were in the range from 2,000 to 3,000 mgㆍL-1 after then. However, K concentration in petiole sap were in the rang from 5,000 to 7,000 mgㆍL-1 The fluctuation in petiole sap concentration of K was severe in the monthly fertigation and moderate in the daily fertigation. The fertigation by petiole sap diagnosis forced EC of soil to be low and yield to increase compared to the control.

The purpose of this study is to select criteria of third party logistics company as the most contribution to the profit of customer company. Based upon literature review and the factor analysis, a total of six factors(Trust, Company reputation, Service capability, Stability, Speciality, Cost saving) when selecting third-party logistics provider, are employed in this research. We selected five experienced experts in business logistics for evaluating the relative weight between these criteria by AHP. The results indicated that the relative importance of service capability was the highest at an analysis conducted on experts.

지역의 자연환경을 평가하기 위하여 식물종 및 식물군락에 의한 평가수법을 검토하였다. 대양(1979), 중서(1980), 오전과 중촌(1989), Haber et al. (1991)의 시스템을 기초로 식물을 종속, 군락레벨로 나누어 평가항목의 시안을 제시하였다. 평가항목은 종속레벨에 대해 총 9항목, 군락레벨에 에 대해 총 15항목이었다. 이들 항목은 종속레벨에 대해 세가지 다른 카테고리로 군락레벨에 대해 네가지 다른 카테고리로 분류되었다. 이들 평가방법은 지역의 환경평가에 즈음하여 공간계획을 증진하고 행정적 문제를 완화하는데 응용될 수 있다고 시사되었다 또 식물종이나 식생의 보전등급 설정에도 응용할 수 있을 것으로 판단되었다.
