Geographical data sets are expensive to create and are very easy to copy because the intellectual property rights for the distribution should be protected. The main object of copyright law is to encourage expression of ideas in tangible form and it extend only to original works, it is limited to control the balance of interests between data producers and user. Because the development of a useful legal framework for both private and public activity in this field is an important issue. This paper presents an intial attempt at such a the effective management strategy intended to support continuing research into the legal protection of geographical information.

Human personal genome sequencing can be done with high efficiency by aligning a huge number of short reads derived from various next generation sequencing (NGS) technologies to the reference genome sequence. One of the major obstacles is the incompleteness of human reference genome. We tried to analyze the effect of hidden gene duplication on the NGS data using the known example of hydin gene. Hydin2, a duplicated copy of hydin on chromosome 16q22, has been recently found to be localized to chromosome 1q21, and is not included in the current version of standard human genome reference. We found that all of eight personal genome data published so far do not contain hydin2, and there is large number of nsSNPs in hydin. The heterozygosity of those nsSNPs was significantly higher than expected. The sequence coverage depth in hydin gene was about two fold of average depth. We believe that these unique finding of hydin can be used as useful indicators to discover new hidden multiplication in human genome.

This study was conducted to investigate the materials deposit policies and service policies of overseas collaborative repositories and provide practical data that can be referred to the management of the collaborative repository in Korea. For this purpose, this study tried to analyzed websites of 7 collaborative repositories and related data. Materials deposit policies were focused on duplicate materials, criteria of materials to be accepted, ownership and withdrawal and service policies were focused on on-site services and off-site services including circulation and document delivery service(electronic copy and photocopy). The results of this study can be used as practical data for the establishment of guidelines for collaborative repository in Korea.

Data Replication makes distributed system and database system improved in availability and performance. But it is difficult to keep strict consistency in data update. Existing algorithms keep strict consistency, but have problems of cost a great deal and delay time. It is to introduce hybrid update propagation algorithm which permits eager update for original copy and propagates lazy update for other copies. Hybrid update propagation algorithm also permits group update in ownership. This algorithm menages replica version in order to control group update consistency. Consistency and performance is improved by combining eager update and lazy update with group ownership. Simulation shows improvement of transaction throughput and response time depending on application and execution environment.

The analysis of DNA microarray data is a rapidly evolving area of bioinformatics, and various types of microarray are emerging as some of the most exciting technologies for use in biological and clinical research. In recent years, microarray technology has been utilized in various applications such as the profiling of mRNAs, assessment of DNA copy number, genotyping, and detection of methylated sequences. However, the analysis of these heterogeneous microarray platform experiments does not need to be performed separately. Rather, these platforms can be co-analyzed in combination, for cross-validation. There are a number of separate laboratory information management systems (LIMS) that individually address some of the needs for each platform. However, to our knowledge there are no unified LIMS systems capable of organizing all of the information regarding multi-platform microarray experiments, while additionally integrating this information with tools to perform the analysis. In order to address these requirements, we developed a web-based LIMS system that provides an integrated framework for storing and analyzing microarray information generated by the various platforms. This system enables an easy integration of modules that transform, analyze and/or visualize multi-platform microarray data.

Purpose - The purpose of this study is to investigate the impact of awareness on the characteristics of a consumers' social commerce. This study examines whether the characteristics of social commerce influence the purchase intentions in accommodating these types of social commerce. Research design, data, methodology - The data for the study were collected and analyzed from a sample of 126 adult customers, comprising both males and females, using social commerce. The survey was conducted and the results aggregated through distributing a copy to each participant. For statistical analysis of the data collected, SPSS 18.0 statistical package was used. Results - The results can be summarized as follows. First, the perceptions about the characteristics of Social Commerce demonstrated a significant effect for attitudes. Second, the attitudes demonstrated positive effects on purchase intention. Third, the subjective norm affected the purchase intention. Fourth, perceived behavioral control influenced the purchase intentions. Conclusions - As a result, perceptions about the characteristics of Social Commerce may be seen in the positive effects on purchase intention. Using social commerce in the future, retailers would need to increase the scope of the study, through applying more diverse characteristics of Social Commerce.

JPMP SID Tag is the security senor tag to provides physical information protective function using sensor module, has impossible feature to copy and fake the data which is stored in the tag. So data which is stored in the JPMP SID Tag has authenticity, integrity, originality. Therefore JPMP SID Tag could be applied in the place where the security of data is demanded. This paper propose the system using the JPMP SID Tag to acquire and protect digital evidence where cause investigation of accident is necessary. Also, proposed systems is complement of software security with composition secondary control logic for JPMP SID tag access control.

The key riboflavin synthesis genes are located immediately downstream of luxG in the lux operon from Photobacterium leiognathi. It is of interest that a site capable of forming a rho-independent terminator does not appear to be present between luxG and ribE in our previous data. These results raise the question of whether the transcription of lux and rib genes is integrated or not. In order to answer the question, in vivo transcriptional assay and Southern blot were examined. These studies demonstrate that neither transcriptional terminator nor promoter site is present in the intergenic region between of lux and rib genes as well as that the riboflavin genes are single copy in a chromosome of Photobacterium leiognathi.

Generally, HDDs are widely used as data storage device in office, home and mobile machineries. So, it is used for various applications or tasks, such as file copy, file download, music and movie play etc., in various environment. In spite of this kind of varieties in tasks and environment in which HDDs perform, most commercial HDDs hardly control its operations adaptively to these varieties. Thus, it is preferred to optimize the performance and energy consumption of HDDs according to the task and/or the environment. So, this paper proposes a new fuzzy inference algorithm which adaptively controls HDDs operations and may also easily be implemented as the firmware of HDDs and run in the restricted environment such as embedded systems.
