Previous studies in various medical specialties have shown that fewer than 50% of abstracts presented at meetings are subsequently published, but only a few studies have been performed in pediatric dentistry. The purpose of this study was to investigate the rate of publication of articles based on abstracts presented at the Korean Academy of Pediatric Dentistry (K.A.P.D) spring and fall Congress for 2001 to 2011. The abstracts for both oral and poster presentation were collected. A RISS search was then performed to identify the publication of full-length articles based on those titles of the abstracts. A total of 822 abstract presentations were done at the 22 meetings (543 as oral presentation, 279 as poster presentations). Of these, 42.2% (347) was subsequently published. The publication ratio for orally presented abstracts was 50.6% (275), poster presentations 25.8% (72). We suggest that presenters at these meetings should expand their abstracts into full manuscripts and seek to publish them in peer-reviewed journals for the benefit of the profession.

The purpose of this study is to seek how to effectively acquire a full-text using LHI(Loca1 Holdings Information) when we search bibliographic DB. For this study, the pre-investigation of LHI within Online and CD-ROM DB was made using local and overseas literature. The questionary survey was made of librarians and users who have used CD-ROM. The finding of this study is that LHI is not very widely used in libraries, thus more study on ,LHI within Online and CD-ROM DB is required to get high quality information service.

In this paper, we determine the required storage capacity of a unit-load automated storage/retrieval system(AS/RS) under random storage assignment(RAN) and n-class turnover-based storage assignment(CN) policies. For each of the storage policies, an analytic model to determine the optimal storage capacity of the AS/RS is formulated so that the total cost related to storage space and space shortage is minimized while satisfying a desired service level. A closed form of optimal solutions for the RAN policy is derived from the model. For the CN policy, an optimal storage capacity is shown to be determined by applying the existing iterative search algorithm developed for the full turnover-based storage(FULL) policy. Finally, an application of the approach to the standard economic-order-quantity inventory model is provided.

In this paper, we consider an amplify-and-forward (AF) full-duplex relay network (FDRN) using simultaneous wireless information and power transfer, where a battery-free relay node harvests energy from the received radio frequency (RF) signals from a source node and uses the harvested energy to forward the source information to destination node. The time-switching relaying (TSR) protocol is studied, with the assumption that the channel state information (CSI) at the relay node is imperfect. We deliver a rigorous analysis of the outage probability of the proposed system. Based on the outage probability expressions, the optimal time switching factor are obtained via the numerical search method. The simulation and numerical results provide practical insights into the effect of various system parameters, such as the time switching factor, the noise power, the energy harvesting efficiency, and the channel estimation error on the performance of this network. It is also observed that for the imperfect CSI case, the proposed scheme still can provide acceptable outage performance given that the channel estimation error is bounded in a permissible interval.

Weyl structure can be viewed as generalizations of Riemannian metrics. We study Weyl structures which are critical points of the squared L$^2$ norm functional of the full curvature tensor, defined on the space of Weyl structures on a compact 4-manifold. We find some relationship between these critical Weyl structures and the critical Riemannian metrics. Then in a search for homogeneous critical structures we study left-invariant metrics on some solv-manifolds and prove that they are not critical.

In this paper we investigate the hardware implementation of block matching algorithms (BMAs) for moving sequences. Using systolic arrays we propose a hardware architecture of a two-stage BMA using integral projections which reduces greatly computational complexity with its performance comparable to that of the full search (FS). Proposed hardware architecture is faster than hardware architecture of the FS by 2~15 times. For realization of the FS and two stage BMA modeling and simulation results using SPW and VHDL are also shown.

In this paper, we propose VLSI architectures for the full search block matching algorithm (FS BMA) and two-stage BMA using integral projections that reduce greatly computational complexity with its performance comparable to that of the FS BMA. The proposed VLSI architectures are faster than the conventional ones with lower hardware complexity. Also the proposed architectures of the FS BMA and two-stage BMA are modeled in VHDL and simulated to show their functional validity.

The multimedia documents becomes the most natural user interface for CSCW(Conputer Supported Cooperative Work) in distributed environment. The objective of this study is to propose a multimedia document architecture and to develop a system that can manage it well. The new architecture is for revisable documents and is the basic layer for hypermedia documents. A good document architecture for CSCW must support pointing, marking, and editing over a part of documents. The user views, version control, and full- content search are also desirable features. In this paper, we discuss the basic concept of a new document architecture for CSCW. We also present the user interfaces for spatio-temporal compositions of multimedia documents.

비구조화된 전문DB는 이용자가 필요로 하는 부분을 지정하여 다양하게 탐색한 수 없고, 또한 부적합 정보가 다량 탐색된다는 단점이 있다. 이러한 문제점을 해결하기 위해서 문헌의 구조화가 시도되고 있으나, 지금까지는 대부분 형태적 논리구조에 기반한 탐색기법이 연구되어 왔다. 따라서 본 논문에서는 문헌의 구조화에 형태적인 논리구조 뿐만 아니라 의미적인 논리구조도 반영될 수 있도록 단락을 객체단위로 한 의미구조 관계를 규명하고 이를 전문DB 구조에 적용하기 위한 타당성을 고찰하였다.
