We have developed a biologist-friendly, stand-alone Java GUI application, IdBean, for ID conversion. Our tool integrated most of the widely used ID conversion services that provide programmatic access. It is the first GUI ID conversion application that supports the direct merging as well as comparison of conversion results from multiple ID conversion services without manual effort. This tool will greatly help biologists who handle multiple ID types for the analyses of gene or gene product lists. By referring to multiple conversion services, the number of failed IDs can be reduced. By accessing ID conversion service online, it will potentially provide the most up-to-date conversion results. The application was developed in modular form; however, it can be re-packaged into plug-in form. For the development of a bioinformatics analysis tool, the module can be used as a built-in ID conversion component. It is available at http://neon.gachon.ac.kr/IdBean/.

Dynamic threshold public-key encryption provides dynamic setting of the group of all users, receivers and the threshold value. Over recent years, there are many studies on the construction of scheme, called ID-based dynamic threshold encryption, which combines the ID-based encryption with dynamic threshold encryption. In this paper, we analyze the ID-based dynamic threshold encryption proposed by Xing and Xu in 2011, and show that their scheme has a structural problem. We propose a conversion method from ID-based encryption which uses the bilinear map to ID-based dynamic threshold encryption. Additionally, we prove this converted scheme has CPA security under the full model.

SAW (Surface Acoustic Waves) ID (identification) tags have been designed and implemented for RFID (Radio frequency IDentification) systems. With SAW ID tag of pulse position encoding method, the data capacity increased 3 times compared with SAW ID tag of amplitude on/off method. Two different kinds of SAW ID tag receiver systems, heterodyne and homodyne receiver systems, were made. The direct conversion receiver showed better isolation property, 10 dB improvement than the heterodyne receiver to increase wireless interrogation distance.

Recently contactless ID system has emerged as new ID industry. It's called RF-ID. RF-ID is divided into active RF-ID and passive RF-ID. The passive RF-ID operates without battery and so has no limitation in its operating range and life time. But it needs the RF-OC conversion circuit. It also can be applied to batteryless sensor for many application. This paper presents the study of the RF-OC conversion circuit for batteryless system in high frequency and confirms it by simulation and experiment.

We have studied DC energy conversion of RF card by wireless communication. In order to attain an objective, it used the system which is a Rectenna. The main purpose of energy conversion system is the operation of the circuits at RF-ID system. The proposed RF-ID system is a lot classified with the reader and tag. Reader is a kind of the base station role supporting RF energy. And priority tag convert RF energy from the reader it was delivered with a wireless to DC energy. The energy which is converted like Tag. It transmits to the reader characteristic ID of each card. The tag is mainly divided into rectifier, power module, memory and controller. The FRAM maintains the data like a ROM in no-power situation. And the advantage is a low power element compared with other EEPROM. There are two considerations, when RF energy is converted into DC source by wireless. One is energy amount supported from the reader, the other is high power efficiency. This paper presents a study of simulation and experiments on the RF-DC conversion circuit in tag by the power efficiency concentrated.

With the growth of AI technology, the scale of Knowledge Graphs continues to be expanded. Knowledge Graphs are mainly expressed as RDF representations that consist of connected triples. Many RDF storages compress and transform RDF triples into the condensed IDs. However, if we try to transform a large scale of RDF triples, it occurs the high processing time and memory overhead because it needs to search the large ID mapping table. In this paper, we propose the method of converting RDF triples using Hash-based ID mapping tables with MapReduce, which is the software framework with a parallel, distributed algorithm. Our proposed method not only transforms RDF triples into Integer-based IDs, but also improves the conversion speed and memory overhead. As a result of our experiment with the proposed method for LUBM, the size of the dataset is reduced by about 3.8 times and the conversion time was spent about 106 seconds.

There are many different ID representation forms depending on the media or applications. In case of RFID tag, ID representation form must be followed by the rule of ISO/IEC 15962. In this study, we developed the efficient ID conversion algorithm between ID representation form on RFID tag and Internet. The main idea is on the use of XML based ID profiles and three step logical IDs forms. The algorithm was tested by the typical three kinds of real IDs such as EPC, ISO/IEC 15459 KKR Code, and mCode which are the typical meta-IDs can be defined in ISO/IEC 18000-6C tag.

It is need to delvelop converting program for using this data to analysis real power system. Conversion consist of bus number and bus name convert, machine's MBASE, X''d, Machine ID, Area, Zone Code, adding tie-line and remove small genererator that was not consider in transient stability analysis. As result of this work, the efficiency of power system analysis is increase and the result input data is used for many analysis applications.

A study was conducted to determine the ileal digestibility (ID) of amino acids and feeding values of spray dried plasma protein (SDPP) and spray dried porcine intestine hydrolysate (SDPI) in early-weaned pigs. Twelve pigs aged 18 days old (Landrace${\times}$Yorkshire${\times}$Duroc; $5.83{\pm}0.51kg$ BW) were cannulated in the terminal ileum for determination of ID of amino acids. Ninety pigs ($6.28{\pm}0.1kg$, 18 days old) were also employed for a feeding trial during phase I period. Treatments were: 1) 6% SDPP, 2) 6% SDPI, and 3) 3% SDPP+3% SDPI. The apparent and true ID values of the essential amino acids except leucine, methionine and valine were lower (p<0.01) in SDPI than in SDPP. The average apparent ID of essential amino acids in SDPP and SDPI were 75.63 and 71.30%, and the average true ID of essential amino acids 84.83 and 80.51%, respectively. The ADG and feed conversion ratio in piglets fed the 6% SDPP diet were better (p<0.01) than in those fed the 6% SDPI diet. When 3% of SDPP was replaced by SDPI, however, the growth rate and efficiency of pigs were comparable to those in pigs fed 6% SDPP. In conclusion, SDPP can be partially replaced by SDPI without any detrimental effect on growth performance in early-weaned pigs.

With the development of 3D-based CAD (Computer Aided Design), attempts at freeform building design have expanded to small and medium-sized buildings in Korea. However, a standardized system for continuous utilization of shape data and BIM conversion process implemented with 3D-based NURBS is still immature. Without accurate review and management throughout the Freeform building project, interference between members occurs and the cost of the project increases. This is very detrimental to the project. To solve this problem, we proposed a continuous utilization process of 3D shape information based on BIM parameters. Our process includes algorithms such as Auto Split, Panel Optimization, Excel extraction based on shape information, BIM modeling through Adaptive Component, and BIM model utilization method using ID Code. The optimal cutting reference point was calculated and the optimal material specification was derived using the Panel Optimization algorithm. With the Adaptive Component design methodology, a BIM model conforming to the standard cross-section details and specifications was uniformly established. The automatic BIM conversion algorithm of shape data through Excel extraction created a BIM model without omission of data based on the optimized panel cutting reference point and cutting line. Finally, we analyzed how to use the BIM model built for automatic conversion. As a result of the analysis, in addition to the BIM utilization plan in the general construction stage such as visualization, interference review, quantity calculation, and construction simulation, an individual management plan for the unit panel was derived through ID data input. This study suggested an improvement process by linking the existing research on atypical panel optimization and the study of parameter-based BIM information management method. And it showed that it can solve the problems of existing Freeform building project.
