IP VPN의 사용은 현재 보편화 되었고 네트워크 장비의 통합 추세에 따라 IP VPN과 방화벽 통합제품의 생산이 활발히 이루어지고 있다. 통합 보안 제품은 비용 효율성과 관리의 편리성, 확장성, 유연성과 같은 장점을 제공하지만 높은 성능 지원을 요구한다. 방화벽의 성능 인자의 하나로서 정책의 개수는 그 수에 비례하여 검색 시간이 지연되는 문제를 발생시키고, 이러한 성능 저하 문제는 VPN과 통합 시 더욱 가중된다. 더욱이 차세대 네트워크인 IPv6로 환경에서는 IP의 비트수가 증가하여 검색 성능 문제 해결이 필수적으로 요구된다. 본 논문에서는 이러한 통합 제품의 검색 성능 문제에 관한 해결 방안으로 IPv6 주소의 특성을 사용한 메커니즘을 제안한다. 제시한 메커니즘은 보안 정책 테이블의 주소 필드를 IPv6 주소에 포함된 인터페이스 식별자로 대체하여 보안 정책 테이블의 검색 속도를 향상시키는 방법이다. 이 방법은 차세대 네트워크 환경에서 주목 되고 있는 보안 및 성능 문제에 대해 큰 역할을 할 것으로 기대된다.

This research reviewed the HIPAA/HITECH, 21st Century Cures Act, Common Law, and private Guidances from the perspectives in protecting and utilitizing the medical data, while implications were followed. First, the standards for protection and utilization are relatively clearly regulated through single law on personal medical information in the United States. The HIPAA has been introduced in 1996 as fundamental act on protection of medical data. Medical data was divided into personally identifiable information, non-identifying information, and limited dataset under HIPAA. Regulations on de-identification measures for medical information, objects for deletion of limited data sets, and agreement on prohibition of data re-identification were stipulated. Moreover, in the 21st Century Cures Act regulated mutual compatibility for data sharing, prohibition of data blocking, and strengthening of accessibility of data subjects. Common Law introduced comprehensive consent system and clearly stipulates procedures. Second, the regulatory system is relatively simplified and clearly stipulated in the United States. To be specific, the expert consensus and the safe harbor system were introduced as an anonymity measure for identifiable medical information, which clearly defines the process while increasing trust. Third, the protection of the rights of the data subject is specified, the duty of explanation is specified in detail, while the information right of the consumer (opt-out procedure) for identification information is specified. For instance, the HHS rule and FDA regulations recognize the comprehensive consent system for human research, but the consent procedure, method, and requirements are stipulated through the common rule. Fourth, in the case of the United States, a trust-based system is being used throughout the health and medical data legislation. To be specific, Limited Data Sets are allowed to use in condition to the researcher's agreement to prohibit re-identification, and de-identification or consent process is simplified under the system.

Purpose: This study was conducted to explore the effects of attitude to death in hospice and palliative professionals on their terminal care stress, and to analyze relationships among variables related to the two aforementioned parameters, such as depression and coping strategies. Methods: Participants were 131 hospice and palliative professionals from the cancer units of two tertiary hospitals and two general hospitals, two hospice facilities, two geriatric hospitals, and two convalescent hospitals in J province. Data were collected from April through June 2015 and analyzed using t-test, factor analysis, ANOVA ($Scheff{\acute{e}}$ test), ANCOVA, and Pearson's correlation and a path analysis using the SPSS/WIN 21.0 and AMOS 18.0 programs. Results: The score for attitude to death was low (2.63), and that for depression was 0.45. Among all, 16.0% of the participants showed need for depression management. They scored 3.82 on terminal care stress. The subcategory with the highest mark was inner conflicts on limitation given availability of medical services (4.04). The score on coping strategy was low (3.13). They used passive coping strategies such as interpersonal avoidance (4.03), fulfilling basic needs (3.65) such as sleeping or eating. Attitudes to death had a direct negative effect on the terminal care stress level and indirectly affected through depression and fulfilling basic needs (CS2). Conclusion: It is necessary to provide hospice and palliative professionals with education on death and dying, as well as access to programs that provide emotional support and promote positive cognition of death and dying.

Purpose: This qualitative study was designed to explore and describe the nursing staff reported experiences of managing the medical needs of nursing home residents in South Korea. Methods: Using a focus group interview method, qualitative data were collected from March to May 2012. Twenty five registered nurses and nurse aids working in nursing homes were recruited through a convenient sampling method. Participants participated in one of four focus group interviews lasted up to two hours in which their day-to-day experiences of taking care of the medical needs of the elderly residents. All interviews were recorded and transcribed in verbatim, and analyzed according to the qualitative thematic analysis method using MAXQDA software. Results: The overriding theme was 'experiencing differences between the requirements of the regulatory system and the actual reality of the work place.' The findings of differences between what were true and what is required was based in four subcategories. The nursing home residents had far more medical needs than what were reported. Another finding was that the family members were seen as non-supportive and negligent towards the residents. Conclusion: The findings of the study support the need for changes in the regulatory system. The regulatory limitations of current system with a shortage of resources pushed the participants to experience discrepancies between the required regulation and the reality. Additional research could contribute more exemplars to support changes.

In relation to telemedicine in Korea's medical law, there are Articles 17, 17-2, and 34 of the Medical Act. Since 'direct examination' in Articles 17 and 17-2 of the Medical Act can be interpreted as 'self-examination' rather than 'face-to-face examination', it is difficult to see the above regulation as a regulation prohibiting telemedicine. Prohibiting telemedicine only with the concept of medical examination or the 'principle of face-to-face treatment' is against the principle of "nulla poena sine lege"(the principle of legality). However, in order to qualify as 'examination', it must be faithful enough to replace face-to-face examination, so issuing a medical certificate or prescription after a poor examination over the phone is considered a violation of the Medical Act. In that respect, the above regulation can be said to be a regulation that indirectly limits telemedicine. On the other hand, most lawyers interpret that telemedicine between medical personnel and patients is completely prohibited based on Article 34, and the Supreme Court recently ruled that such telemedicine is not permitted even if there is a patient's request. However, this interpretation is not only far from the legislative intention at the time when telemedicine regulations were introduced into the Medical Act of 2002, but also does not match the needs of reality or the legislative trend of foreign countries. The reason is that telemedicine regulations are erroneously legislated. The premise of the legislation is wrong, and there are considerable problems in the form and content of the legislation. As a result, contrary to the original legislative intent, telemedicine was completely banned. In foreign countries, it is difficult to find cases where telemedicine is completely banned and criminal punishment is imposed for it. In order to fundamentally solve the problem of telemedicine, Article 34 of the Medical Act needs to be deleted.

The amount of image data used in medical institution is increasing rapidly with great development of medical technology. Therefore, an automation method that use image processing description, rather than manual macrography of doctors, is required for the analysis large medical data. Specially, medical image registration, which is the process of finding the spatial transform that maps points from one image to the corresponding points in another image, and 3D analysis and visualization skills for a series of 2D images are essential technologies. However, a high establishment cost raise a budget problem, and hence small scaled hospitals hesitate importing these medical visualizing system. In this paper, we propose a visualization system which allows user to manage datasets and manipulates medical images registration using an open source graphics tool - VTK(Visualization Tool Kit). The propose of our research is to get more accurate 3D diagnosis system in less expensive price, compared to existing systems.
