본 논문에서는 기존 C++ 컴파일러에서 검출하지 못하는 클래스 멤버의 접근성을 위반하는 연산을 정의한다. C++에서는 접근 지정자로 클래스 멤버의 접근성을 선언하도록 하고 있다. 접근 지정자 중에서 private과 protected는 객체 외부에서 접근할 수 없는 멤버 지정을 위해서 사용된다. 그러나 C++ 의 포인터 연산을 이용하면 객체 외부에서 private이나 protected 접근성을 가지는 멤버로 직접 접근 가능하다. 본 논문에서는 멤버 접근성을 위반하는 연산의 원인과 사례를 보이고 이를 정형적으로 정의한다. 본 논문의 공헌은 기존에 다루어지지 않은 문제인 멤버의 접근성을 위반하는 연산을 정의하는 것이다.

차량 애드 혹 네트웍 (VANET)은 모바일 애드혹 네트워크의 일종으로써 차량 간의 임시적인 통신을 가능케 한다. VANET의 모바일 노드는 네트웍의 일원으로 참여하면서 에너지와 자원을 사용한다. 몇몇의 노드는 다른 노드와 협력하는 대신에 자신의 이득만을 취하려고 하는 이기성을 가지고 있다. 이러한 이기성을 가진 노드들로 인해 데이터 접근성과 네트웍의 효율성이 감소하게 된다. 이 논문에서는 새로운 기법인 VANET 그룹에서 이기성을 갖고있는 노드를 제거하는 Friendship-VaR을 제안한다. Friendship-VaR은 이기성을 갖고있는 노드를 제거하고 믿을 수 있는 노드들간에 데이터 공유를 가능케 한다. Friendship-VaR는 간단한 데이터 교환을 통해 노드의 이기성 여부를 결정한다. 실험 결과는 제안한 기법이 기존의 기법에 비해 데이터 접근성이 좋아짐을 보여준다.

There exists dead zone from the aspects of health equity and health medical equity for maritime personnel. They could not have been benefited from disease prevention and health promotion in comparison with shore personnel due to the restricted medical accessibility caused by long voyage ship operation. Furthermore, the system of health management and medical assistance for maritime personnel is insufficient, the continuous health monitoring system does not exist, nor health diagnosis system, maritime industrial accidents and occupational disease control systems are adequate. The International Maritime Organization and the International Labour Organization recommend their Member Governments to take necessary measures in the management of seafarers' health and diseases through conducting continuous and systematic investigation. Thus, this study intends to propose action strategy and tasks for introducing marine telemedicine system aiming to provide seafarers with health management service for the years to come. The conclusions of this study can be given as follows. First, it is required that a systematic medical service system needs to be provided to promote seafarers' health. Second it is recommended to establish the marine telemedicine system incorporating U-Health technology. Third, it is necessary to revise the relevant laws and regulations to introduce the marine telemedicine system. Fourth, it is also necessary to provide various assistance system at the national level in the furtherance of global marketing of marine telemedicine system.

This study aims to compare the healthcare status of South Korea and other member of the Organization for Economic Cooperation and Development (OECD) using the OECD health statistics 2021. We used the position value for relative comparison (PARC) index to measure the five elements of the healthcare system, demand, supply, accessibility, quality, and cost. For the statistical analysis, Mann-Kendall test was performed to examine the trend of the PARC values from 2000 to the most recent year. The results showed that supply, demand, accessibility, and quality were above median than the OECD median and the cost was below median. In sectors such as primary care, health employment and mental health care were below median average. With these result, necessary steps for a sustainable healthcare should be taken into effort by policy makers.

This study examined the trend of healthcare status and compared the status of South Korea and other member of the Organization for Economic Cooperation and Development (OECD) using the OECD health statistics 2022. We used the OECD health statistics from 2022 and a position value for relative comparison (PARC) index to compare the five elements of the healthcare system. The study also used a Mann-Kendall test to analyze the trend of the PARC values from 2000 to the present year. The findings of the study indicate that many South Korea's PARC values were higher than the OECD median. But practicing physician in supply part and medical cost were lower than OECD median but the trend significantly increased. Medical accessibility part and quality of care part except primary care, and mental health had a high relative position but the trend did not increased significantly. After outbreak of coronavirus disease 2019, there were changes in medical accessibility. Health screening and vaccinations showed an overall decline in 2020 compared to 2019. These results suggest that policymakers need to take necessary steps for a sustainable healthcare system in the country.

In terms of water meter reading, the majority of 16 million houses use mechanical water meter in korea. So, a member of the utility's staff needs to access periodically the water meter and the value of the metered volume. However, due to the use of mechanical water meter, many issues have been appeared as cost, time, errors, accessibility, and readability. To settle these issues, we developed the walk-by meter reading system of digital water meter and outside indicator based on ubiquitous. And we could get the characteristics and the economical efficiency for water meter reading system. Thus, this study shows that the system can be widely used to the block system and the meter reading system for stable water supply.

MANET is a network that is a very useful application to build network environment in difficult situation to build network infrastructure. But, nodes that configures MANET have difficulties in data retrieval owing to resources which aren't enough and mobility. Therefore, caching scheme is required to improve accessibility and availability for frequently accessed data. In this paper, we proposed a technique that utilize mobility prediction of nodes to retrieve quickly desired information and improve data availability. Mobility prediction of modes is performed through distance calculation using location information. We used technique which global cluster table and local member table is managed by cluster head to reduce data consistency and query latency time. We compared COCA and CacheData and experimented to confirm performance of proposed scheme in this paper and efficiency of the proposed technique through experience was confirmed.

The handicapped as a member of a society should possess the same opportunity of a perfect participation in public affairs and an equal opportunity in parity of treatment. All sorts of physical and social barriers surrounding the handicapped who can not having a impairment and disability give a less chance to have a share in their society. Therefore, this discrimination barriers must be phased off not only by handicapped but also by normal social members so as to perfect and free access to movement, all of social institution and social activities. Therefor, this paper provides a basic data which conducts investigation and analysis on the outdoor access environment for the handicapped's easy access to public building or facilities. It would be most import rules to make a decision between improvement rate and object for public building or public facilities.

This study investigated the healthcare status of South Korea and member states of the Organization for Economic Cooperation and Development (OECD). By employing the position value for relative comparison index, healthcare status was measured through the following components: demand, supply, accessibility, quality, and cost. Statistical analysis was conducted through the Mann-Kendall test from analyzing trends from 2000 onwards. Results showed that while Korea, on average, scores higher than the OECD average in most of the investigated components, it is below average in certain indexes including primary care and mental health care. Considering the various health issues that have been raised about these indexes, it is important these components be improved upon by policy-makers.
