과거 서지DB 제작시스템은 자료의 수집부터 DB제작에 이르기까지 자료입수지연 및 서지데이터입력오류, 중복레코드생성, 권호정보의 부정확한 기입, 철자오류와 관련된 많은 문제들을 내포하고 있었다. 본 연구는 이와같은 문제들을 최소화하기 위해 SISAC기반 서지DB 제작시스템을 설계 구현하였다. 이 시스템은 기존 가용자원을 최대한 활용하기 위해 SISAC 바코드를 스캐닝하여 자료의 입수처리를 신속하게 하고, 서지데이터를 입력할 때 기존에 구축된 데이터를 공유함으로써 데이터 중복입력으로 인한 시간소모적인 작업을 줄인다. 그리고 개방형 환경에서 양질의 능력을 지닌 DB제작 전문가를 선정하는데 투명성을 제공하고, 이들 DB제작전문가를 활용함으로써 데이터의 품질향상에 기여한다.

In the construction industry, construction management system using information technology has been applied diversely to increase productivity. Although IT device such as PDA, RFID, Barcode, wireless network and web camera has been introduced in construction site, the usage of these device is restricted, because these cause engineer to do additional work. The suggested process using Digital Pen in this study, which can lessen engineer's additional work, get defect data promptly. Also accumulated data is utilized effectively for analyzing construction site. The purpose of this study is to introduce Digital Pen System as a means of construction data acquisition for improving productivity.

We developed the BaSDAS (Barcode-Seq Data Analysis System), a GUI-based pooled knockout screening data analysis system, to facilitate the analysis of pooled knockout screen data easily and effectively by researchers with limited bioinformatics skills. The BaSDAS supports the analysis of various pooled screening libraries, including yeast, human, and mouse libraries, and provides many useful statistical and visualization functions with a user-friendly web interface for convenience. We expect that BaSDAS will be a useful tool for the analysis of genome-wide screening data and will support the development of novel drugs based on functional genomics information.

Cymbidium goeringii is one of the most important and popular species in the orchid family in north-east Asia. In the present study, we prepared multiplex PCR system, and used it for the genotyping of eight simple sequence repeats (SSR) markers (CG409, CG415, CG709, CG722, CG787, CG1023, CG1210, and CG1281) in subject with 40 samples of cultivated varieties. All the analyzed samples showed different combined genotypes. The average combined power of discrimination was very high value of $7.14{\times}10^{-10}$, and observed heterozygosity (Ho = 0.466) was similar with two wild populations of C. goeringii, which may indicate no or little occurrence of genetic change after collection from wild habitats. The present study also developed a two-dimensional barcode to express information of genotype results of eight SSR markers (SSR DNA ID). The discrimination power of DNA ID between two individuals will be statistically more than 99.999999%. The SSR DNA ID and two-dimensional barcode may be very usefully applied for the discrimination and maintence of cultivars of C. goeringii.

Multi-product mass production small and medium enterprise factories have a wide variety of products and a large number of products, wasting manpower and expenses for inventory management. In addition, there is no way to check the status of inventory in real time, and it is suffering economic damage due to excess inventory and shortage of stock. There are many ways to build a real-time data collection environment, but most of them are difficult to afford for small and medium-sized companies. Therefore, smart factories of small and medium enterprises are faced with difficult reality and it is hard to find appropriate countermeasures. In this paper, we implemented the contents of extension of existing inventory management method through character extraction on label with barcode and QR code, which are widely adopted as current product management technology, and evaluated the effect. Technically, through preprocessing using OpenCV for automatic recognition and classification of stock labels and barcodes, which is a method for managing input and output of existing products through computer image processing, and OCR (Optical Character Recognition) function of Google vision API. And it is designed to recognize the barcode through Zbar. We propose a method to manage inventory by real-time image recognition through Raspberry Pi without using expensive equipment.

Recently, the demand of labels for product management is increasing, as the automation system becomes more common. the development of functional labels which can be used in various environments has been rapidly proceeded. In the case of a printed circuit board, barcode labels with thermal and chemical stability are generally used due to a high temperature process around $300^{\circ}C$ and chemical cleaning in the manufacturing process. However, the yellowing phenomenon of labels that can lower the resolution of printed barcode image still needs to be prevented. In this study, we prepared a composite coating layer using a silica inorganic binder and a titanium dioxide white pigment, and developed a functional labels with thermal and chemical stability. The silica inorganic binder prepared by sol-gel process was confirmed to show excellent adhesion and abrasion resistance with the polyimide film. The white coating layer could be formed on the polyimide film with mixing the silica inorganic binder and titanium dioxide white pigment. The prepared coating layer showed excellent whiteness and glossiness above $400^{\circ}C$. The excellent chemical stability of the coating layer was also confirmed by the chemical treatment with acidic (pH 1.6) and basic (pH 13.6) cleaners.

A voice coil actuator with moving coil type for scanning mirror system of barcode reader has been developed. The actuator has a simple structure including a magnet, a coil and a pin. The performance of the actuator is analyzed by a linearized theoretical model. And the dynamic performance of the proposed actuator is predicted through motor constant and restoring constant obtained by finite element simulations. The theoretical model was verified by the prototype which has 64 Hz resonance frequency and 60 deg reflecting angle. We also discovered that that 3 V input can make the actuator rotate over 61.8 deg reflecting angle at 50 Hz resonance frequency. The proposed actuator can simplify its driving configuration because of its implementation of open-loop control.

Conventional bar code has the appearance of line bars and spaces, called as one-dimensional bar code. In contrast, the information in two-dimensional bar code is represented by either a small, rectangular or square with the types of mosaic and Braille. The two-dimensional bar code is much more efficient than one-dimensional bar code because it can allow to store and express large amounts of data in a small space and so far there is also a little information about decoding the Data Matrix in base 256 mode. According to the ISO international standards, there are four kinds of bar code: QR code, Data Matrix, PDF417, and Maxi code. In this paper, among them, we focus on describing the basic concepts of Data Matrix in base 256 mode, how to encode and decode them, and how to organize them in detail. In addition, Data Matrix can be organized efficiently depending on the modes of numeric, alphanumeric characters, and binary system and expecially, we focus on describing how to decode the Data Matrix code by four modes.

Over five thousand higher fungal specimens were collected from 32 forest areas of Chungcheong and Gyeongsang province from 2012 to 2013. We obtained 513 strains and 3,120 ITS sequences. Mushrooms were first identified with macro- and micro-scopic characters, and their identification was confirmed on the basis of ITS sequences. Voucher specimens were designated for each species found in Korea. Construction of DNA barcoding Database is currently underway with sequences of 409 species. During the development of the database, some new species were recognized, along with several Korean new records. When the system has been completed, it will provide essential molecular information for metagenomic and phylogenetic researches for higher fungi.

본 논문은 종래에 코인투입구에 동전, 지폐 등의 현금을 사용하여 상거래 활동에 사용되고 있는 기기장치의 코인/지폐 인식부를 리더/라이터 RF ID단말장치로 대체하므로 기기장치의 생산단가를 낮출 수 있다. 매장운영에 있어 기존 사용되는 코인기가 장착된 기기장치의 가장 불편하게 여겨졌던 동전의 계산, 노동력, 시간 경비 등을 낮출 수 있으므로 매장운영 관리하는데 있어서 보다 효율적으로 운영하는 효과가 발생하게 되었다. 매장에 방문하는 고객을 회원으로 유치할 수 있는 Mobile Barcode System을 연동하여 종전 고객을 기다리는 것이 아니라 매장에서 고객을 유치할 수 있는 고객 마케팅, 매장운영 시스템을 제안한다.
