Simple sequence repeats (SSRs) are ubiquitous short tandem duplications found within eukaryotic genomes. Their length variability and abundance throughout the genome has led them to be widely used as molecular markers for crop-breeding programs, facilitating the use of marker-assisted selection as well as estimation of genetic population structure. Here, we report a software application, "SSR-Primer Generator " for SSR discovery, SSR-primer design, and homology-based search of in silico amplicons from a DNA sequence dataset. On submission of multiple FASTA-format DNA sequences, those analyses are batch processed in a Java runtime environment (JRE) platform, in a pipeline, and the resulting data are visualized in HTML tabular format. This application will be a useful tool for reducing the time and costs associated with the development and application of SSR markers.

Customer satisfaction is generally assumed to be a significant determinant of repeat sales, positive word-of-mouth, and customer loyalty. Therefore most companies in telecommunication industry have tried to satisfy customers with high quality at low price in Korea. Even though these efforts have been tried by companies, customers are not satisfied with discrepancy between their expectation and perceived quality. Moreover, the expectation has dynamic and variable characteristics in results from various effects such n technical progress, improved quality and promotions by companies, word-of-mouth, and so on, Therefore, there are not political leverages in assessing the quality and surveying customer satisfaction index in a point of time. As an initial attempt to tackle the questions listed above, this paper puts an effort to make a dynamic customer satisfaction model to understand customer satisfaction in variable situations by introducing 'systems thinking'.

When a MCCB Instant trip spring which is adjusted to notrip at -20% of each current from $5{\times}In$ to $10{\times}In$ and trip +20% of those is designed, we should know attraction force between Fixed Magnet and Armature. So we first made some samples, do experiments of weight, and simulated the modelling by 3D Maxwell S/W. With values of experiment and simulated values, we do design instant trip springs and repeat the above process. Finally we set up the Process of designing Instant spring. With it, we can save time and R&D cost.

In order to provide design concept and guidelines for the user interface of MIDAS$^{TM}$(Medical Image Display and Archiving System), a questionnire survey and empirical study were conducted. User and task requirements were analyzed based upon usrvey results. The empirical study was done on the 1.0 version of MIDAS to find out the influence of user charactenistics (i.e.job, experiences, etc.) and UI design factors(i.e. layout, wording, procedures) on various usability measures(i.e. performance, satisfaction). To perform empinical tests, eight task scenarios were selected and user interactions were recorderded using an auto-logging software. The results show that the doctor group requires more learning time. Also, eight types of user errors such as commision, omission, repeat were identified and the causes of the errors were analyzed related to UI design factors. UI design guidelines were suggested for a new version of medical image filing system.m.

Application of color coding to a jack board-type display has not yet been tried. The purpose of this paper is to study the effects of color coding on a jack board-type display. Ten subjects searched 10*20 arrays of numbers for the presence or absence of a color coding. Five colors were used for the coding. Three subjects were selected among 10 subjects to repeat 11 times the above experiments. Detection time was reduced by 6.6% for the color coding condition. Three subjects did not show any results different from those in their inexperienced state, except the learning effect during repetition of the experiments. The results imply that the color coded jack board-type display may be efficient either to inexperienced subjects or to experienced subjects.

We are encountering a great numerous informations concerning literatures to rapidly organize and manage, and the necessity for education of library science has been increasing for social service at the right time. The distribution of the library materials to policy-making vital to modernization of Korea has been greatly estimated. Accordingly, at present it is very urgent for us to re-examine the curriculum in each of college library science course. Therefore, we should not repeat such a rediculous education of library science as ten-years old one. A new way should be designed, so that students could carry out their activity of literatures, informations and services which is necessary for modernization of Korea. Thus this essay proposes the following points; This is designed for pioneering to improve and develope the education of library science.

In this paper, the interferometric coherence was estimated and the amplitude intensity was extracted using the repeat-pass interferometric data, acquired by European Remote Sensing Satellite 1 and 2. Then discrimination and classification of surface land types in Zhangjiakou test site, Hebei Province were carried out based on the coherence estimation and the intensity extraction. Seven types of land were discriminated and classified, including in two different types of meadows, woodland, dry land, grassland, steppe and water body. The backscatter and coherence characteristics of these land types on the multi-temporal images were analyzed, and the change of surface features with time series was also discussed.

Several pretreatment methods have been developed to reduce the inorganic arsenic, which is known to be highly harmful to humans, among various arsenic species present in hijiki and rice. The pretreatment methods were selected and developed as methods that can be non-harmful even after treatment and easily applied. Hijiki was applied by two methods. One was soaking in water at room temperature for various durations and the other was boiling of it in water for a short period of time. Rice was soaked in water with different rice-to-water ratios for various durations. The most effective method that reduced the inorganic arsenic in hijiki was to repeat parboiling for 5 minutes twice, which led to 79% reduction of the inorganic arsenic in it. In the case of rice, soaking for 24 hours at the ratio of 1:5 (rice:water) resulted in 51% reduction of inorganic arsenic in rice.

Semisulcospira libertina, a species of freshwater snail, is widespread in East Asia. It is important as a food source. Additionally, it is a vector of clonorchiasis, paragonimiasis, metagonimiasis, and other parasites. Although S. libertina has ecological, commercial, and clinical importance, its whole-genome has not been reported yet. Here, we revealed the genome of S. libertina through de novo assembly. We assembled the whole-genome of S. libertina and determined its transcriptome for the first time using Illumina NovaSeq 6000 platform. According to the k-mer analysis, the genome size of S. libertina was estimated to be 3.04 Gb. Using RepeatMasker, a total of 53.68% of repeats were identified in the genome assembly. Genome data of S. libertina reported in this study will be useful for identification and conservation of S. libertina in East Asia.

Regular expression pattern matching is widely used in applications such as computer virus vaccine, NIDS and DNA sequencing analysis. Hardware-based pattern matching is used when high-performance processing is required due to time constraints. ReCPU, SMPU, and REMP, which are processor-based regular expression matching processors, have been proposed to solve the problem of the hardware-based method that requires resynthesis whenever a pattern is updated. However, these processor-based regular expression matching processors inefficiently handle repetitive operations of regular expressions. In this paper, we propose a new instruction set to improve the inefficient repetitive operations of ReCPU and SMPU. We propose REMPi, a regular expression matching processor that enables efficient iterative operations based on the REMP instruction set. REMPi improves the inefficient method of processing a particularly short sub-pattern as a repeat operation OR, and enables processing with a single instruction. In addition, by using a down counter and a counter stack, nested iterative operations are also efficiently processed. REMPi was described with Verilog and synthesized on Intel Stratix IV FPGA.
