It is worth it to properly present the behaviors of cyberspace and game characters. It is not so easy to manually supply the actions for all objects one by one, so we need to use crowd animation techniques in order to display automatically, realistically, and effectively. In this paper, we construct a ubiquitous cyber aquarium based on sensors, using the crowd behavior library, which is applied to programming crowd behavior in cyberspace and game applications. We use a sensor board to become aware of a person approaching the cyber aquarium, and according to the perceived distance, the objects in the cyber aquarium automatically react and behave accordingly.

Augmented reality technology was invented for military purposes at the beginning. But the development of wireless and location based technology in 2000s makes AR services reach the age of innovation. Especially, it attracts attention as a media which enriches our perception. There is a potential that it can extend the virtual information in the real world from optical sense to auditory, tactile, and olfactory sense. This study proposed the interactive information service system and method based on AR. To do it, technical background on AR was analyzed and a method to apply the technology was examined. Especially, as a eco service, this study proposed new information service using 2D bar code in a library for user need and convenience in ubiquitous environment. The proposed service system can optimize practical utilization of information resources in virtual and real reality as consolidating analog and digital resources in a library.

The metallothionein (MT) gene (IbMT3) was selected from an EST library of suspension-cultured sweet potato cells. The MT gene, which is one of abundant ESTs in the library, is involved in stress regulation of cells and tissues. A full-length IbMT3 cDNA was obtained and analysis of its nucleotide sequence revealed that IbMT3 encoded a type 3 MT protein, based on its structural characteristics. The function of type 3 MT in plants is not yet known. Northern blot analysis showed stronger expression of IbMT3 in suspension-cultured cells than in sweet potato plant leaves. Since cell culture is known to impose a state of oxidative stress on cells, sweet potato plants were subjected to oxidative stress to investigate the transcriptional regulation of IbMT3. When the herbicide methyl viologen (MV) was administered for 6, 12, and 24 hr, IbMT3 transcription rapidly increased at 6 hr and then decreased. A cold treatment at $15^{\circ}C$ for 24 and 48 hr resulted in a gradual increase in IbMT3 expression. These findings indicate that IbMT3 expression is regulated in response to environmental and oxidative stress. IbMT3 isoform is expected to have antioxidant effects in sweet potato plants and may play an important role in cellular adaptation to oxidative stress.

Nowadays many academic libraries have considered and some have implemented the just-in-time(access) approach to collection development especially of scholarly journals. The adaption of the scholarly electronic journal based on access paradigm has brought a number of advantages and disadvantages to academic libraries. Electronic journals have promised rapid delivery of the latest research to the desktop through the ubiquitous platform of the Internet. But the promise of the e-journal is not yet a reality, and there are many misconceptions about what is actually available today. The objective of this paper is to analyse the probabilities of digital achilles tendon of scholarly journals resulting from a decline of purchase power, absence of selection(evaluation) criteria, superfluities and abuses of impact factor, access paradigm and halo effects, mismatching of demand-supply, md insufficiency in subject gateway functions.

This study is to analyze the present publishing media in order to grasp the trend of data development and distribution. For this, I analyze the present tendency, concentrating indices of diagram, dividing into traditional book and e-book. It also discusses the viewpoint extracted from the problems related to the data development and distribution of publishing media. Traditional books and e-books have been expending to add newly updated convergence media in digital media era in which internet represents. I discuss these changes to convergence media for the realization of 'ubiquitous' mean the evolution to transmit propagational elements from proper character of traditional book. By the same token, I examine prospect of increasing digital publishing media and other problems before distribution.

The novel BrRZFPs genes encoding C3HC4-type RING zinc finger protein were identified from FOX (full length cDNA over-expressing) library of Brassica rapa. Ten full-length cDNAs obtained from the library encode zinc-finger protein containing 346 amino acids, designated BrRZFPs. These genes were classified into four groups by phylogenic analysis showing conserved protein sequences at both termini. The tissue distribution of BrRZFPs transcription was examined by qRT-PCR revealing ubiquitous expression pattern. However, each gene was strongly expressed in the specific tissue. Transcriptional analysis showed that those acquired 10 genes were inducible under abiotic stresses. Likewise, the transcript of BrRZFP3 was strongly induced (~12-folds) by exogenous abscisic acid, whereas the transcripts of BrRZFP1, BrRZFP2 and BrRZFP3 were (> 9-folds) induced by cold. We suggest that these BrRZFPs that function as signal or response to abiotic stress are useful for crop improvement.

The major aim of this study is to discuss the possibility whether the merging of Information Literacy and rhetoric will be able to have essential elements for being a general education subject in universities. The characteristic of rhetorical information literacy (RIL) is organized as follows. Situated literacy using heuristic method, process oriented literacy attaching importance to research, and literacy relevant to ubiquitous environment. So, it is argued that rhetorical information literate citizenry is essential for a modern democratic society. As the information literacy instruction program can be various, for example, technology oriented instruction is needed to be compared. For the practical execution of the RILI program, 'asking situated questions to discover problem', 'selecting and writing review of meta study books', and 'writing visiting report of library', and 'instruction of information ethics for democratic citizens' have been proposed.

A cDNA clone encoding chloroplast triosephosphate isomerase (TPI-cp) was isolated from strawberry fruit cDNA library. Sequence analyses indicated that the cDNA contains an open reading frame of 314 amino acids (33.5 kDa) composed of a transit peptide (59 amino acids) in amino terminal region and mature protein (255 amino acids). The existence of transit peptide in the deduced amino acid sequence implies that it encodes a chloroplast isoform. The protein sequence is more similar to other plant chloroplast isoforms than cytosolic isoforms. RNA blot analysis indicated that its expression is ubiquitous in examined five tissues, flowers, leaves, petioles, roots and fruits, and shows differential pattern according to fruit ripening. Genomic DNA blot analysis showed that TPI-cp is encoded by multiple genes in strawberry. Through sequence comparison and phylogenetic tree construction, TPI-cp is distinctively grouped into dicot and chloroplast isoforms.

The ubiquitous plasma membrane $Na^+/H^+$ exchanger 1 (NHE1) is rapidly activated in response to various extracellular stimuli and maintains normal cytoplasmic pH. Yeast two-hybrid screening was used in order to identify proteins interacting with NHE1 using its cytoplasmic domain as a bait from HeLa cDNA library. One of the interacting cDNA clones was human Lactate dehydrogenase B (LDHB). In vitro translated LDHB was pulled down together with GST-NHE1.cd protein in the GST pull down assay, confirming the interaction in vitro. LDHB antibody immunoprecipitated endogenous LDHB together with NHE1 from H9c2 cells, validating cellular interaction between NHE1 and LDHB. Subsequent analysis revealed that the overexpression of LDHB increased intracellular PH, implying opening of the NHE1 transporter. Moreover, overexpression of LDHB activated caspase 3 and induced cell death, consistent with the expected phenotype of hyper-activation of NHE1. Collectively, our data indicate that LDHB modulates NHE1 activity via physical interaction.
