  • A routing policy based on BGP community routing permits to select a specific route for particular network by making use of user-defined routing policies. Especially, community based routing policy is recently getting a great concern to enhance overall performance in the global research networks which are generally inter-connected large number of different characterized networks. In this paper, we analyze the community routing which has been applied in existing global research networks in the network performance point of view, and catch hold of problems caused by the routing performance in a new global research network. Then, we suggest an effective community routing policy model along with an interconnection architecture of research networks, in order to make correct some wrong routings and resolve an asymmetric routing problem, for a new global research network. Our work is expected to be utilized as an enabling base technology to improve the network performance of future global research networks as well as commercial networks.

  • This study analyzed a correlation between South China Sea summer (June to September) monsoon (SCSSM) and the ENSO for the last 32 years (1979 to 2010). There was a correlation that the higher (lower) the SST in the $Ni{\tilde{n}}o-3.4$ region was, the weaker (stronger) the SCSSM intensity was. To identify the reason for this correlation, a difference of means between 8 El $Ni{\tilde{n}}o$ years and 8 La $Ni{\tilde{n}}a$ years (June to September). The analysis on the difference between two groups with respect to the 850 hPa stream flows showed that there were anomalous huge cyclones in the subtropical Pacific in the both hemispheres so that cold and dry anomalous northerlies were strengthened in the South China Sea relatively while anomalous westerlies were strengthened from the Maritime Continent to the off the coast of Chile. The analysis on the difference between two groups with respect to the 200 hPa stream flows showed that the opposite anomalous pressure system pattern to that in the 850 hPa stream flows were shown. In the subtropical Pacific of the both hemispheres, anomalous anticyclones existed so that anomalous easterlies were strengthened from the Maritime Continent to the equatorial central Pacific. Considering the anomalous atmospheric circulations in the upper and lower layers of the troposphere, upward airflows from the equatorial central and eastern Pacific were downward in the South China Sea and the Maritime Continent, which was a structure of anomalous atmospheric circulations. This means that the Walker Circulation was weakened and it was a typical structure of atmospheric circulations revealed in El $Ni{\tilde{n}}o$ years.

  • The floating population that is index to figure out dynamic activities in urban area will be important in urban railway planning, but it is not useful because it is collected by posterior method. This study aims to investigate factors influencing floating population. The floating population data that was collected in Seoul for a month in December 2013 is used as dependent variable, and the negative binomial regression analysis is used in modelling. The number of households, number of employees, number of subway stations, and number of bus lines variables are statistically significant in predicting floating population.

  • Purpose: This study was done to propose an improvement in the Nursing Fee Differentiation Policy to alleviate polarization of nursing staffing level among hospitals and to rectify the confusion of legally mandated standards between the Korean Medical Law and National Health Insurance Act. Methods: The policy regulation was reconstructed related to nurse staffing standards and nurse-to-patients ratios. Data on nurse staffing grades were obtained from database of the Health Insurance Review & Assessment Service (HIRA) for the third quarter of 2010 for 44 tertiary hospitals, 274 general hospitals, and 1,262 hospitals. A break-even analysis was used to estimate financial burden of the revised policy improvement proposal. An industrial engineering method was used to calculate Nurse-to-Patients ratios per shift. Results: Twelve tertiary hospitals were downgraded. 74 general hospitals and 102 hospitals were upgraded after application of the regulation. Finances for total hospitalization expenditures changed from -3.55% to +3.14%. Conclusion: The results indicate that the proposed policy would decrease polarization between tertiary hospitals and small hospitals, and would not put a major strain on the finances of the Korean National Health Insurance. Therefore, it is suggested that government stake-holders and many interest groups consider this policy proposal and build a consensus.

  • With the ready access to the high resolution satellite image data, users of and areas covered by satellite image data are constantly on the rise world-wide. Korea will also be able to take full advantage of the satellite data once the KOMPSAT is successfully launched. Harmonizing satellite data production and application technology and users' needs, along with the guiding policy is essential for promoting satellite data use. Up to now, the Korean government has mainly concentrated on developing production technology for the satellite units. However, the imminent task of independent satellite data production demands a promotion policy for satellite data use. In this context, the policy is defined as an important medium for identifying the role and status of satellite image information at the national level and also Preparing the legal as well as systematic foundation for producing, building, distributing, and packaging satellite data. For example, in the countries with the advanced satellite technology, such as the United States, the United Kingdom, and Australia, digital ortho image and digital elevation model (DEM) are mandatorily included in the National Geographic Framework Data through policy measures. In addition, in order for the efficient provision of the satellite data, separate organization or agency is being in operation for the exclusive production and distribution of the satellite data. The present paper aims to examine the role and status of the satellite data as well as their current status and problems in Korea in reference to the National Spatial Data Infrastructure, and finally to provide the policy directions to promote the satellite data use in public sector on the basis of the preceding analyses.

  • As Open Data has been emphasized globally, discussions on data policies have occurred for minimizing problems resulting from data sharing and reuse. This study aimed at investigating policy components for controlling access and use of data and examining similarities and differences of the policy components across disciplines. For the purpose, the study analyzed policy components for data access and use controls provided by 37 research data repositories overseas. These included twenty repositories in biological and health science, ten in chemistry, earth and environmental science and physics, as well as seven in social science and general science. The analysis showed that common policy components involve copyright/licenses, data citation, disclaimers and embargoes. However, there were differences in diversity of policy components among the disciplines and it indicated that the rationales of access and use controls emphasized would be different in the disciplines.

  • Korean society has been recently promoting the restoration of coastal wetlands. These efforts might become the basis of a policy framework that compensates for the limitations of a regulation-oriented policy such as the designation of Marine Protected Areas (MPAs). The shift in government policy could contribute to strengthening the socioeconomic infrastructure of coastal development through the accumulation of ecological capital. Although our scientific efforts and social demands in regard to the ecological restoration of the coastal wetlands have increased during the past years, the bases for restoration in Korea requires that scientific, technological, financial, social and legal aspects be enhanced. The present study re-examined the concept and attitudes behind coastal wetland restoration in the light of changing circumstances in Korea. Herein, we first defined coastal wetland restoration as "An act of recovering the functions of the ecosystem of coastal wetlands to a state that resembles conditions prior to being damaged." Next, this study discussed the limitations and future directions of such restoration efforts based on the descriptive analyses of recent restoration practices from social, economic, and technological aspects. Finally, we suggest future policy directions regarding coastal wetland restoration on the basis of a PFST (Policy, Financial, Social, and Technological) analysis; 1) re-arranging legal mechanisms, 2) setting multi-dimensional restoration goals, 3) establishing a multi-discipline- and convergence based R&D system, 4) linking spatial management and local development to the restoration, 5) building restoration governance at the local level, 6) implementing an ecosystem service payment system, and 7) applying test-bed projects in accordance with proper directions.

  • Gastric cancer is common cancer generating about 20% incidence in Korea. But Oriental medical doctor (OMD) often can't measure therapy on gastric cancer positively because that the prognosis on it is not good. It is impossible the results on all of diseases not only gastric cancer always to have to be good. It is required to find out the causes of diseases and therapy method to conquest the diseases for the medical therapy. But because the results on medical therapy are not always good, it is necessary for the doctor who want to treat the diseases like gastric cancer having the prognosis to be death to protect himself, like as the legal system, a medical policy. And consequently, this protecting legal system lead the medical therapy principle or method on some special diseases to therapy completion on it. As a results of policy, medical therapy have to be developed. It is studied the literature referencing gastric cancer, experimental articles to insist the effects of Oriental medicine planet to gastric cancer and the clinical cases on gastric cancer to be treated as Oriental medicine therapy to have effects. Recently, there have been many other development in oriental medical therapy. This development can be grouped as two type. One type is clinical part and the other is experimental research part. Specially the experimental research and clinical research on gastric cancer in oriental medical therapy have been developed. So the present day is the time to make medical policy on liver cancer for OMD to measure oriental medical therapy and develop oriental medical theory. As a above results, we propose that the name of gastric cancer have to use in Korean medicine security clinical name (한방의료보험상병명) to make oriental medical policy.

  • The purpose of this study is to investigate the factors affecting family caregiver financial burden of out-of pocket expenses for the nursing home service under Long-term Care Insurance System. We conducted a national cross-sectional descriptive survey from July to September 2010 to collect data based on the long-term care benefits cost specification. Total 1,016 family caregivers completed questionnaires. 185 subjects of total were excluded from the data analysis due to being answered by user(18 cases), or caregivers not to pay for services expenditures(122 cases), having a missing data on family caregivers characteristics(45 cases). Finally, 831 subjects were included in the study. The average financial burden was 3.18(${\pm}0.71$). We divided subjects into two groups by level of burden, high-burden group and low-burden group. In the result of the multiple logistic regression analysis, family caregiver financial burden was significantly higher in family caregivers with ages 40 to 49 compared to less than 40, lower educational level, unsatisfaction for long-term care service, high percentage(more than 50%) of cost-sharing and high total out-of pocket expenses(more than 300,000 won) for long-term care services. Also, Family caregivers who are spouse felt higher financial burden compared to son. This study is meaningful as the first attempt to measure family caregiver financial burden for long-term care service and to identify factors affecting the financial burden. Family caregivers felt financial burden of out-of pocket expenses for the nursing home service. The policy makers, the insurer, and the providers need to pay attention to ease family caregiver financial burden.

  • To establish an appropriate policy for robotic surgery in Korea, the National Evidence-based Collaborating Agency (NECA) and the Korean Society of Health Policy and Administration held a round-table conference (RTC) to gather opinions through a comprehensive discussion of scientific information in gastric cancer. The NECA RTC is a public discussion forum wherein experts from diverse fields and members of the lay public conduct in-depth discussions on a selected social issue in the health and medical field. For this study, representatives from the medical field, patient groups, industry, the press, and policy makers participated in a discussion focused on the medical and scientific evidence for the use of robotic surgery in gastric cancer. According to the RTC results, robotic surgery showed more favorable results in safety and efficacy than open surgery and it is similar to laparoscopy. When the cost-effectiveness of robotic surgery and laparoscopy is compared, robotic surgery costs are higher but there was no difference between the two of them in terms of effectiveness (pain, quality of life, complications, etc.). In order to resolve the high cost issue of the robotic surgery, a proper policy should be implemented to facilitate the development of a cost-effective model of the robotic surgery equipment. The higher cost of robotic surgery require more evidence of its safety and efficacy as well as the cost-effectiveness issues of this method. Discussions on the national insurance coverage of robotic surgery seems to be necessary in the near future.
