  • 자바카드의 큰 특징 중의 하나는 바로 필요한 응용프로그램이나 Library를 카드가 발급된 후에도 카드 상에 업로드 시켜 이용할 수 있다는 것이다. 하지만 카드를 발급할 때 Mask형태로 ROM상에 올려져 있는 API의 경우 수정하는 것이 불가능하며 또한 단순히 새로운 API를 추가한다 하더라도 기존에 이를 사용하던 애플릿의 변경이 불가피 하게 된다. 본 논문에서는 발급 후 API를 추가하는 예를 보이고 이런 문제점을 개선한 모델을 제시하여 보다 유연한 API 개발 환경을 제공하게 한다.

  • The Article 17 (1) of the Medical Service Act states that no one but medical doctor, dentist or herb doctor shall prepare medical certificate, post-mortem examination, certificate or prescription. Though medical certificate, post-mortem examination or certificate is a private document issued by doctor personally, it is accepted as reliable as public document. Therefore, for medical certificate, post-mortem examination or certificate, unlike other private document to guarantee authenticipy of the content, the Article 233 of the Criminal Act states the Crime of Issuance of Falsified Medical Certificates. In other words, the Criminal Act Article 233 states that If a medical or herb doctor, dentist or midwife prepares false medical certificate, post-mortem examination or certificate life or death, one shall be punished by imprisonment or imprisonment without prison labor for not more than three years, suspension of qualifications for not more than seven years, or a fine not exceeding thirtht million won. The subject of the Crime of Issuance of Falsified Medical Certificates is only a medical or herb doctor, dentist or midwife and the eligibility requirements are specified in the Medical Service Act. Medical certificate is the medical document to be issued by medical doctor to certify the health status and show the Jugdement about the result of the diagnosis, Post-mortem examination is the document to be listed by medical doctor to confirm medically about human body or dead body, and Certificate life or death is a kind of medical certificate to verify the fact of birth or death, the cause of death, such as Birth Certificate, Certificate of Stillbirth or Certificate of Dead Fetus. To constitute the crime of Issuance of Falsified Medical Certificates, it is necessary for the contents of the certificate to be substantially contrary to the truth, as well as it is needed the subjective perception that the contents of the certificate are false. The Supreme Court Decision 2004DO3360 Delivered on March 23, 2006 declared that although the Defendant did not MRI scan, etc. for precise observation about the disability status of Mr Park, it was difficult to believe that the contents of the Disability Certificate of this case were contrary to the objective truth or the defendant had perception that the contents of the certificate were false. I don't agree with the Supreme Court Decision, because the Supreme Court confirmed the decision by the court below despite the Supreme Court should have made the court below retry the reason why the Defendant did not MRI scan, etc. for precise observation about the disability status of Mr Park.

  • Java Card has gained genera1 acceptance with standard for smart card and (U)SIM technology, and it is in distinction from native card by its post-issuance of an application and independence from hardware platforms. However, a main weak point of Java Card is its low execution speed caused by the hardware limitation and Java programming language itself. In this paper, we propose a new Java Card Installer to improve the download speed during the post-issuance of an application by resolving symbolic references to physical references in HAM. Our Resolution_In_RAM is based on the improved new RAM writing is 100,000 times faster than EEPROM writing and PageBuffer that is operated as block mode, rather than cell mode is used to write to EEPROM. Consequently, the total number of EEPROM writing are reduced 37%, and the times of downloading are reduced over 30% by using the Resolution_In_RAM-based Java Card Installer.

  • 개방형 카드 플랫폼의 개발로 전통적인 카드 플랫폼 모델의 문제점을 해결할 수 있었으나 기존 카드 관리시스템으로 개방형 카드 플랫폼을 관리 할 수 없었고 그 대안 시스템으로 SCMS가 개발되었다. SCMS가 개방형 카드 플랫폼에 있어 통합 관리를 수행하지만 주요 기능인 카드 후발급에 대한 효과적인 인터페이스를 가지고 있지 못하다. 본 논문에서는 스마트카드 관리시스템을 이용하여 효과적인 카드 후발급을 위한 카드 후발급 인터페이스를 설계하였다.

  • Today, the activities of individuals and corporations are dependent not only on digital technology but also on the future of society, which is referred to as the fourth industrial revolution. Since the traces that arise from the crimes that occur in the digital society are also inevitably developed into a society that should be found in the digital, the judicial dependence of judging by the digital evidence is inevitably increased in the criminal procedure. On the other hand, considering the fact that many users are using virtual shared computing resources of service providers considering the fact that they are being converted into a cloud computing environment system, searching for evidence in cloud computing resources is not related to crime. The possibility of infringing on the basic rights of the criminal procedure is increased, so that the ability of evidence of digital data which can be used in the criminal procedure is limited. Therefore, considering these two aspects of digital evidence, this point should be fully taken into account in judging the evidence ability in the post-seizure warrant issuance and execution stage as well as the pre-emptive control. There is a view that dictionary control is useless, but it needs to be done with lenient control in order to materialize post-modern control through judging ability of evidence. In other words, more efforts are needed than ever before, including legislation to ensure proper criminal procedures in line with the digital age.

  • This study examines the impact of corporate governance on capital structure decisions based on a large panel of Chinese listed firms. Using the system Generalized Method of Moments (GMM) estimator to control for unobserved heterogeneity, endogeneity, and persistency in capital structure decisions, we document that the ownership structure plays a significant role in determining leverage ratios. More specially, we find that managerial ownership has a positive and significant impact on firms' leverage, consistent with the incentive alignment hypothesis. We also find that managerial ownership only affects the leverage decisions of private firms in the post-2005 split share reform period. State ownership negatively influence leverage decisions implying that SOEs may face fewer restrictions in equity issuance and may receive favourable treatments when applying for seasoned equity ¿nancing, thus use less debt. Furthermore, our results show that while foreign ownership negatively influences leverage decisions, legal person shareholding positively influences firms' leverage decisions only for state controlled firms. We also find that the board structure variables (board size and the proportion of independent directors) do not influence firms' capital structure decisions. Our findings suggest that recent ownership reforms have been successful in terms of providing incentive to managers through managerial shareholdings to take risky financial choices.

  • AMR(Automatic Meter Reading), which means that it reads the meter of electricity, gas, or water, etc at a remote place automatically through wired or wireless communication, has been studied in terms of Power Line Communication method and Local Area Wireless Communication method, etc. In this paper, we designed and implemented JCA(Java Card for AMR) capable of AMR, which is based on java Card technology indispensable to the ubiquitous world. In this paper, JCA follows standard transactional procedures offered by power supply company and manages power usage log and billing data, and is designed in order to satisfy EMV multi-functional specifications. Because JCA is a multi-functional smart card capable of post-issuance applets as an open platform, it is installed into other applications of affiliated concerns as well as credit card and traffic card applications. Not only the proposed JCA is a low cost system, compared to other AMR systems, but is capable of paying rates in advance or later by applying authentication and security function of java Card. In addition the proposed JCA system can create value added services such as affiliated services with corporate alliance.
