X-beam structure and Pressure Tank having X-beam structure
No full text본 발명의 X축 , Y축 , Z축 방향으로 연장되는 복수개의 빔이 격자형태로 형성되고, X축 빔, Y축 빔, 및 Z축 빔이 만나는 복수개의 교차부를 포함하고, 각 빔의 단면이 직각의 X자 형태인 X자형 빔구조물은 하나의 빔이 연속되게 형성되는 메인축과 상기 메인축에 서브축이 결합·용접되어 상기 교차부를 형성하는 것을 특징으로 한다.또한, 본 발명의 X자형 빔구조물을 갖는 압력탱크는 내부에 고압의 유체가 수용되고, 각형(prismatic shape)으로 제작되는 탱크본체를 더 포함하고, 상기 X자형 빔구조물은 상기 탱크본체의 내부에 위치하고, 상기 탱크본체의 일측벽으로부터 마주하는 타측벽으로 도달하며 규칙적으로 직교배열되는 것을 특징으로 한다
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
