    A Study on Reform of SW Appraisal System with focus on the Governance Theory

    Kim, Si Yeol | Choi, Jae-Sik | 2017, 13(1) | pp.1~14 | number of Cited : 0
    Abstract PDF
    In Korea, there are arguing for intellectual property governance, In this situation, the issue of copyright appraisal system means a lot to us. In this paper, we have pointed out importing the new SW appraisal system including SW copyright appraisal.

    SPDX Parser and Validator for Software Compliance

    Ho-Yeong Yun | Yong-Joon Joe | Byung-Ok Jung and 1other persons | 2017, 13(1) | pp.15~21 | number of Cited : 0
    Abstract PDF
    Analyzing a software package which is consisted of big numbers of files takes enormous costs and time. Therefore, SPDX (Software Package Data Exchange) working group collaborate with Linux Foundation published a software information(metadata) specification: SPDX. On the first half of 2017, the specification contains seven chapters and 66 items, according to Ver 2.1 of SPDX spec. It prefers Tag/Value or RDF forms but also supports spreadsheet form. In this paper, we introduce SPDX parsing & validation tools to check the validity of SPDX document. We'll develop SPDX document generator to manage software package more efficiently for our next target.

    Modification of SW Cost Estimation Guideline for the Appraisal of Software Development Cost

    Kwon, Ki Tae | 2017, 13(1) | pp.23~30 | number of Cited : 0
    Abstract PDF
    The development cost appraisal of the computer program has been assumed that the appraiser to determine such as development costs on the process from the software engineering aspects. “Completeness appraisal guidelines of a computer program” can be used as a guideline for complete appraisal business, is to provide the procedures and methods for the development costs and the degree of completion of computer programs. For more information about the software development costs calculation, we can refer to the "SW cost estimation guide". Although successful appraisal of a number of development costs based on the guide has been processed, in this paper, we propose a solution to solve the problem [1] that arises when applying the "Guide to calculating the SW cost" when appraising the development cost.

    A Comparative Study on the Performance of Source Code Similarity Measurement Tools

    Gyoosik Kim | SEONG JE CHO | Jinwoon Woo | 2017, 13(1) | pp.31~42 | number of Cited : 1
    Abstract PDF
    Because software is everywhere and has continued to play a major part in our daily lives, software piracy and plagiarism are still rampant. The tools has been developed and used in order to detect pirated copies of software at source code level. JPlag, MOSS, and exEyes are well-known source code plagiarism detectors. In this paper, we explain briefly different types of classical code clones, and compare the performance of JPlag and exEyes using Java source code files. The performance comparison between JPlag and exEyes are conducted using a benchmark, BigCloneBench which is a big benchmark of real clones. We evaluate the performance of the tools measuring their precision, recall, and F-measure. Experimental results show that both precision and recall rates of the two tools become 100% for simple type-1 and 2 clones. For more complicated type-3 clones, however, JPlag and exEyes have a precision rate of 95% and 100%, and a recall rate of 50.1% and 27.7% respectively.

    A Practical evaluation for a display Device

    LEE KYU TAE | Lee HyunChang | HYUNMOOK CHO and 1other persons | 2017, 13(1) | pp.43~49 | number of Cited : 0
    Abstract PDF
    For keeping copyright, a copyright evaluation is to verify an illegal modification between the original product and the suspected product. On comparing two products, a copyright association take an estimation to the original product and illegal product. The evaluation experts have to compare both products based on the request list from the copyright association. Then after it is excluded from the comparison item as detail to seeking objective result. These detailed comparison item should be a serious concentration cause it has a sensitivity for the decision. In this paper, it was analyzed and illustrated the detailed item as for display device evaluation materials.

    Performance Analysis on the Dynamic Connection Structure in Data Centers

    Ki Jang Geun | 2017, 13(1) | pp.51~55 | number of Cited : 0
    Abstract PDF
    The data communication infrastructure in the future consists of hundreds of thousands of computers and storages running complex application service programs. Future applications are characterized by non-linear scalability and relatively unpredictable rapid growth. In order to meet the dynamic requirements of application services, the method for effective allocation and flexible usage of hardware resources such as computers and storages is needed. In this paper, for the reconfigurable flexible data center infrastructure, the optical switch control algorithm is developed and simulated for performance evaluation.

    A Study on the Interrupt Software Technique for Driving Dynamic Display Circuit

    Lee HyunChang | Sung Yeol Kwon | 2017, 13(1) | pp.57~64 | number of Cited : 0
    Abstract PDF
    In this paper, the software technique for driving dynamic display circuit using timer interrupt is proposed. As proposed technique makes the display software independent of main program, the algorithm of main software becomes simple. On the other hand, as display timing is fixed by the interrupt from timer circuit of micro-controller, the timing of switching becomes precise. In order to verify the effectiveness of proposed software technique, experimental circuit is designed as Timer Interrupt generator into the 4 MHz micro-controller. Experimental results show that proposed software technique controls switching digits of 7-segment exactly, and main software algorithm become very simple.

    A Study on the Improving Education Method of C-language for the Enhancing Ability of Constructing Software

    Lee HyunChang | Keun-Young Choi | 2017, 13(1) | pp.65~72 | number of Cited : 0
    Abstract PDF
    In this paper, improved education method for the enhancing ability of constructing software was proposed. Although purpose of proposed method is C-language education, but it include the interesting display result of HTML and the fun of Web-page. On the other hand, as all of student can watch Web-pages of other student, then interest of education can be increased. In order to verify the effectiveness of proposed education method, experimental Web-server is constructed as Pentium-PC with Red-Hat Linux, Apache HTTP daemon and gcc compiler. Experimental results show that the record of student was increased highly.
