Researchers create nano-material with “ultimate porosity”

Chemists in the USA at the University of California, Los Angeles (UCLA) and in South Korea at Soongsil University say they have created a nano-material with the “ultimate porosity” – achieving world records for both porosity and carbon dioxide storage capacity in an important class of materials known as metal–organic frameworks (MOFs).

Female Trance in Han Tae-Sook's Production of Lady Macbeth

In this article, Jung-Soon Shim indicates how Han Tae-Sook transforms Lady Macbeth's subconscious into an interculturally emotional space in which the Christian concept of guilt and the Korean ethos of Han intersect. In this way, the director conducts an intercultural dialogue, negotiating the Western world view in Shakespeare's Macbeth together with the traditional Confucian-shamanistic world view to be found in Korea. Jung-Soon Shim is Professor of English at Soongsil University in Seoul, currently President of the Korean Theatre Studies Association (KTSA), and a founding member and President of the Korean Association of Women in Theatre (KAWT). Her numerous books include Twenty-First Century Korean Women Theatre Directors (2004).

An Integrated Personal Mobility Management Framework based on RFID in Heterogeneous Fixed and Mobile Networks

Event Abstract Back to Event An Integrated Personal Mobility Management Framework based on RFID in Heterogeneous Fixed and Mobile Networks Yun-Won Chung1* 1 Soongsil University, South Korea Personal mobility (PM) enables users to receive services through any terminal based on unique user identifier (UID) [1]. Although manual registration was needed in conventional PM [1], automatic registration using RFID technology has been proposed recently [2,3]. In [2,3], if a user with RFID tag moves into home or office, RFID reader in fixed terminal detects the RFID tag and registers the user with the terminal at registrar. Then, services can be delivered to the registered terminal, and handoff between terminals can be provided seamlessly. In [2,3], however, only fixed terminal is considered but both fixed and mobile terminals should be considered together in order to achieve true PM in future network.In this poster, we propose an integrated PM management framework based on RFID technology, as in Figure 1, where mobile networks such as cellular network and WLAN and fixed networks such as home network and office network are interworked based on all-IP core network. SIP proxy, redirect, and registrar servers are used to provide PM. Service to a user is delivered based on a chain of location information at registrar and access network: the relationship between UID and registered terminal IDs (TIDs) is managed by registrar and the location information of registered TIDs is managed by access networks. For example, the location information of mobile terminals (MTs) in cellular network is managed by home location register (HLR) by terminal mobility management. Home and office gateways also manage the location information of users moving within their domains with RFID technology. Service to UID is intelligently delivered based on the quality of service (QoS) requirement of a requested service and user preference in the service profile stored in registrar. If the delay is a more important QoS requirement, parallel forking to all registered terminals can be used. If the cost is a more important user preference in the service profile, the service is firstly delivered to a fixed network and if not found, mobile network is searched. Our future work includes performance analysis of the proposed PM management based on detailed registration and delivery procedures with QoS requirement and user preference in the service profile.

Stellar Rotations around a Global Monopole with NUT Charge in the Brans-Dicke Gravity

Stellar Rotations around a Global Monopole with NUT Charge in the Brans-Dicke Gravity Tae Hoon Lee Department of Physics and Institute of Natural Sciences, Soongsil University, Seoul 156-743 (Received 2 November 2007, in nal form 11 March 2008) We consider a global monopole spacetime with Newman-Unti-Tamburino (NUT) charge in the Brans-Dicke theory and determine, within the weak gravity approximation, the asymptotic structure of the spacetime whose origin coincides with a galactic center. We discuss its implications for stellar rotation curves of the galaxy with a softened isothermal dark halo. PACS numbers: 04.50.+h, 14.80.Hv, 95.35.+d

The Shaman and the Epic Theatre: the Nature of Han in the Korean Theatre

The distinctively Korean concept of Han evokes a pervasive sense of sorrow, traditionally in need of shamanistic purging in the spirits of the dead, but also describing the sense of national trauma induced first by the Japanese occupation, then by the post-war division of the country. Han has also become an important feature of modern Korean drama, and in this article Jung-Soon Shim describes how Park Joh-Yeol's play The Toenails of General Oh (1974) revisits the concept, integrating indigenous cultural traditions – notably the shamanic ritual Gut – and how, in the production by Sohn Jin-Chaek, the director utilized a western style of epic theatre to create a ‘distanced’ style of Gut on the proscenium stage. Jung-Soon Shim is Professor of English at Soongsil University in Seoul, and a founding member of the Korean Association of Women in Theatre (KAWT), of which she is currently President. Her books include the two-volume Globalization and Korean Theatre (2003), which won the Best Book of the Year Award of the Korean Ministry of Culture. She also received the Best Critic Award for 2004 from the Korean Association of Theatre Critics. Her research for this article was supported by Soongsil University.

Corporate Governance from a Comparative Perspective: Specific Applications of the Duty of Loyalty in Korea

ARTICLES CORPORATE GOVERNANCE FROM A COMPARATIVE PERSPECTIVE: SPECIFIC APPLICATIONS OF THE DUTY OF LOYALTY IN KOREA Jae Yeol Kwon* I. INTRODUCTION A major concern in contemporary corporate law in the United States is the fiduciary obligations of corporate directors. 1 In the United States, corporate directors are fiduciaries who stand in a distinct legal relationship ' 2 with and thus owe cer- tain legally enforceable duties ' 3 to the corporation and its share- holders. 4 Although the concept of fiduciary duties is difficult to * Associate Professor of Law, College of Law, Soongsil University, Seoul, Ko- rea.
