  • The infrastructure of the country and society is connected to cyberspace. Malicious codes that steal financial information from websites such as plastic surgeons, dentists, and hospitals that are confirmed as IP in Daegu South Korea area are spreading In particular, financial information is an important privacy target. Takeover of financial information leads to personal financial loss. In this paper, we analyze the recent pharming malicious code that takes financial information. Attack files with social engineering methods are spread as executables in the banner, disguised as downloaders. When the user selects the banner, the attack file infects the PC with malicious code to the user. The infected PC takes users to the farming site and seizes financial information and personal security card information. The fraudulent financial information causes a financial loss to the user. The research in this paper will contribute to secure financial security.

  • The speed of technology development is increasing, and high-performance digital devices are spreading. Smart walks that can work effectively anytime and anywhere by being restricted from space and time in wired digital devices such as PC, System security design is needed to secure integrity and availability against various security threats such as physical threats such as lost, stolen and damaged terminals, technical threats such as theft, denial of service, and unauthorized access, compared with the wired environment. In this paper, we analyze smart work network system, wired / wireless link system, and digital smart device. We study security design method for smart work wired system and future wireless system which are used in present work. This study will be used as basic data for building a secure smart work.

  • Smart Phone supplies are diffused and substitute the Internet PC with Mobile communications which they are applied. Smart Phone in Smart Grid where electric power watch and the IT of existing amalgamate are used with business. Consequently from Smart Grid network connections which lead Smart Phone in about connection and control in about security vulnerabilities and Smart Grid networks the research is necessary in about vulnerability. It uses Smart Phone from the present paper and when approaching electric power watch systems which lead Smart Grid networks, it researches in about connection vulnerability. Also it uses Smart Phone and after connecting in Smart Grid networks a vulnerability in seizure possibility and, electric power information and control information, about private data etc. access authority it analyzes with the problem point which occurs it confronts it researches. And the research direction for a security reinforcement under presenting boil in about Smart Grid network security vulnerabilities which lead Smart Phone.

  • Assessment of APC has focused on large size, specialization, and structuralization based on business performance. In the future, first, it should be complemented to have correlation with management efficiency. Second, because of the rate of weight for each index, it is necessary to develop a specific index or adjust allotting of marks so that there can be correlation between indexes. Third, since APCs have high values in the composite assessment and low values in the sales amount, it is necessary to develop various kinds of indexes, including the index to evaluate processing value-added, that of customer satisfaction with assessment, and that of customer relationship maintenance performance through introduction of a customer relationship management system (CRM), in pursuit of balance. Lastly, the results of this study are expected to be able to help make APCs efficient in relation to integration of production organizations so that they will convert and develop into a basic product processing center in coping with changes in internal and external environment of agricultural marketing.

  • 본 논문에서는 경제의 글로벌화를 반영하는 세계적인 현상인 국제회계기준 채택에 대하여 회계 관련사항을 내재하고 있는 기업의 전사적 관리 소프트웨어인 국산 ERP 시스템에 대하여 세금처리의 투명성을 향상시킬 수 있는 방법론적 모델을 해외 ERP의 장점을 통하여 연구한다. 국제회계기준은 기업요소에서 가장 중요한 자본의 국제적인 이동이 기본적 사항으로 기업의 소재지에 대한 국가표시와 관계없이 재무제표의 정보가 투명하고 비교 가능하도록 국제적으로 단일한 회계기준이 사용을 요구한다. 이러한 환경 변화에 따라 국제회계기준(International Financial Reporting Standards: IFRS)의 필요성과 중요성이 확대되어지고 있으며 국제회계기준위원회(International Accounting Standards Board: IASB)의 영향력까지 강화되어지고 있다. 본 논문은 국제회계기준에 맞춘 회계처리 부분의 투명성 향상 모델을 연구하기 위하여 국내에서 많이 사용되고 있는 국산 ERP 소프트웨어 프로그램에 대하여 국제회계기준과 상반되는 현상을 유발하는 기준이 되는 부분을 상호 보완할 수 있는 해외 ERP 소프트웨어 프로그램을 기반으로 기업 시스템을 분석, 구현한다. 국산 ERP 시스템의 국제회계기준 처리와 관련된 단점은 송장의 수정, 삭제가 용이하며 수정, 삭제 후 이력이 남지 않는 부분이다. 이 부분은 국제회계기준에서는 신뢰성에 대한 중대한 문제를 유발하므로 외산 ERP패키지의 장점인 수정과 삭제 단계가 계층적이며 수정, 삭제를 하더라도 필수적으로 이력전체가 저장되는 시스템을 연구하며 특히 세금처리 부분이 상이한 점을 보완하기 위한 모듈을 추가한다. 수정, 삭제에 대한 이력관리는 담당자의 전문적 능력평가와 동시에 실수와 오류부분에 대한 통계를 통하여 관리의 향상성을 추구하여 투명성이 향상된 모델 구축에 활용할 수 있다.

  • The government has the duty to prevent abuses of monopoly and promote competition in order to maximize consumer welfare. In order to promote competition we have to address the asymmetry in the information as possible and to ensure consumer choice. The subsidy seems to reduce the burden on the consumer service charges and handset prices but it virtually distort the market through price discrimination. The government caused the principal-agent problem by avoiding their appropriate role to prevent distortion of the mobile telecom market. The money used as subsidy could be transferred to down the price of cell phone and charges and it would be a benefit to consumers. Separate notice of subsidies by Mobile Communications Terminal Distribution Structure Improvement Act is a developed policy but it was too late. It, the market price close to that from perfect competition structure, is plausible, ultimately.

  • In Korea mobile phone subscribers exceeded 1 million people in 1995, and ten million people in 1998. Prevalence of the mobile phone increased dramatically over 110% compared to the population. And all family members including children and students use one or two mobile terminal. Mobile phone is obviously necessary good more than washer, vacuum cleaner, passenger car. Our daily life with mobile communication are conveniently positioned, but communication related costs including the price of the device has become a big burden on the household. But the government does not seem to do the right role at the right time to prevent the failure of the market to further maximize consumer welfare and social welfare through fair competition. This principal-agent problems exist especially in perspective of joint use of the mobile communication network, number portability, separation of phone distribution and phone service and network neutrality among in mobile communication policies since the early 1990s up to now.
