Unlike in traditional row-oriented database systems, a column-oriented database system stores data in column-oriented and not row-oriented order. Recently, research results revealed the effectiveness of column-oriented databases for applications such as data warehouse and decision support systems that access large volumes of data in a read only manner. In this paper, we investigate the join strategies for column-oriented databases and prove the effectiveness of column-oriented databases in data warehouse systems. For unbiased comparison, the two database systems are analyzed using the star schema benchmark and the performance analysis of a star schema join query is carried out. We experimented with well-known join algorithms and considered early materialization and late materialization join strategies for column-oriented databases. The performance results confirm that star schema join queries perform better in terms of disk I/O cost in column-oriented databases than in row-oriented databases. In addition, the late materialization strategy showed more performance gain than the early materialization strategy in column-oriented databases.

This study aims to explore the theoretical and practical potentials of the late modern social space theories concerning deinstitutionalization issues in the field of the Mental Health. Deinstitutionalization, the process of converting the living space mentally ill people from facilities to the community, is a meaningful event realizing the modern ideology of human rights and welfare in social work territory. Although the continuos and accumulative efforts to realize the ideas of deinstitutionalization, which have focused on the ideological validity and the conditions and administrative supports needed for materialization, however, discussing the issues without analyzing late modern societal space neglects the constraints of the generic and comprehensive 'space' in which the deinstitutionalization can actually occur. Thus, this study attempts the following by analyzing the concrete reality of social space: focusing on deinstitutionalization in a larger social context, different from previous studies that discussed it on a normative and fragmentary level; and more concretely analyzing the realistic limits and challenges facing deinstitutionalization. In order to do this, previous literature related to deinstitutionalization is laid out and theories of late modern social space are studied. Based on this, the kinds of phenomenon that occur when this sort of late modern social space meets with the deinstitutionalization of mentally ill people are analyzed. Finally, based on the results, the study suggests several implications to realize the rights and welfare of mentally in the late modern space concerning deinstitutionalization.

Body has been high-lightened as one of the most important theme since the philosophy and the arts are focused on it in the late 20 century. Resurgence of interests in human body has been based on the skepticism on rapid digitalization and do-materialization currently undergoing in electronic media environments. Artists have been endeavoring more and more to find a synthesis which links the conceptual and the sensuous in their works as digitalization gets faster and faster. The Bodily-oriented art uses its visceral qualities, either literally or metaphorically, to engage our total being, not just our mental consciousness, in building a sensuous, evocative statement. Its transcendent ideas are inter- mixed with the fabric of the world. We are touched by this art not only because we understand it cognitively, but because we "feel"it. These characteristics of textile arts caused gradual increase of soft-sculpture works using textiles and implies possibilities of inter-grade of physical and mental world. Ann Hamilton, Magdalena Abakanowiz, Folly Apfelbaum and Pallid Dougherty are, for example, related to the fiber arts. It would be of worth to study the characteristics of contemporary faber-art works, especially done by Abakanowiz who has been regarded as a dominant pioneer in the contemporary fiber arts from the viewpoint of inter-grade of the physicals and the mental. This paper, therefore, deals with the Abaknowiz′works in the context of human body and body-signs. Life and works might be classified into 5 stages; first, learning period since her birth in 1930, second, creation period of Abakan, third, remodelling period of Abakan, fourth, composition and dissolution period of Abakan and the last and fifth, new transformation period of Abakan. ′Abakan′through her whole life as an artist has been a plastic language and based ultimately on external human body but in various materials and forms.

Chinyoung(親迎) is one of the detailed procedures of a wedding ceremony, of which the bridegroom visits the bride's home to receive and bring her to his home. And, Procession Illustration (班次圖) is a type of drawing that shows how people of various social classes are arranged in their predetermined positions in a royal ceremony. Thus, 'Chinyoung Procession Illustration(親迎班次圖)' refers to the drawing of the march in the course of Joseon's royal wedding ceremony, in which the bridegroom receives and brings the bride to his home. This paper aims to reconstruct the Chinyoung Procession Illustration for a princess as an image, which has never been done. There are no drawings or pictures of the princesses' Chinyoung Procession, but only written records. Thus, we completed the Procession Illustration by dressing the participants in accordance with their social classes and arranging them in the march. The arrangements were based on historical records of social classes, positions, number, and costumes. As for the princesses' weddings in the late Joseon period, a total of 18 wedding records remain. We selected Princess Bok-On's (福溫公主: 1818~1832) wedding as the subject of reconstruction as it had the greatest number of participants. In addition, due to the great number of participants, this study limits its focus to the female participants, with the male participants to be examined in future research. The result confirmed that the number of participants in Princess Bok-On's Chinyoung Procession was 184, including the bride and bridegroom, and the number of female participants was 26 in total, including the princess and women placed around her. The women participants wore Rip(笠), Neoul(羅兀), Jeonmo(氈帽), Garima(加里磨), Noeui(露衣), Hwaleui(豁衣), Dangeui(唐衣), Jeogori(赤古里), Chima(赤亇), Malgun(袜裙), Daedae(大帶), Onhye(溫鞋), Dokhye(禿鞋).
