To provide the end-to-end service differentiation for assured services, the random early demotion and promotion (REDP) marker in the edge router at each domain boundary monitors the aggregate flow of the incoming in-profile packets and demotes in-profile packets or promotes the previously demoted in-profile packets at the aggregate flow level according to the negotiated interdomain service level agreement (SLA). The REDP marker achieves UDP fairness in demoting and promoting packets through random and early marking decisions on packets. But, TCP fairness of the REDP marker is not obvious as for UDP sources. In this paper, to improve TCP fairness of the REDP marker, we propose a modified REDP marker where we combine a dropper, meters and a token filling rate configuration component with the REDP marker. To make packet transmission rates of TCP flows more fair, at the aggregate flow level the combined dropper drops incoming excessive in-profile packets randomly with a constant probability when the token level in the leaky bucket stays in demotion region without incoming demoted in-profile packets. Considering the case where the token level cannot stay in demotion region without the prior demotion, we propose a token filling rate configuration method using traffic meters. By using the token filling rate configuration method, the modified REDP marker newly configures a token filling rate which is less than the negotiated rate determined by interdomain SLA and larger than the current input aggregate in-profile traffic rate. Then, with the newly configured token filling rate, the token level in the modified REDP marker can stay in demotion region pertinently fir the operation of the dropper to improve TCP fairness. We experiment with the modified REDP marker using ns2 simulator fur TCP sources at the general case where the token level cannot stay in demotion region without the prior demotion at the negotiated rate set as the bottleneck link bandwidth. The simulation results demonstrate that through the combined dropper with the newly configured token filling rate, the modified REDP marker also increases both aggregate in-profile throughput and link utilization in addition to TCP fairness improvement compared to the REDP marker.

With the recent opening of The National Library for Individuals with Disabilities, interests in library services for the disable have been increasing. For the purpose of promoting library services for the disabled all the more, the study is to provide cooperative plans in policy between the social welfare and the library and information service based on library perceptions of social workers as specialists in disability and welfare fields. Cooperative plans in policy provided by this study are as follows: (1) The unique communication channel between librarians and social workers should be constructed through social networks. (2) Public relations on the value and necessity of both the library and librarians should be enhanced. (3) Education on the expertise of the social welfare for librarians should be enriched. (4) Clear-cut identities between librarian's and social worker's tasks should be established.

This paper is designed to make a national strategic concept for the ROK's maritime security and to explore cooperation directions for the ROK Navy and Coast Guard in order to implement the newly-made maritime security strategic concept. As strategy is composed of three main categories(goals, ways, means), the goal of the ROK's maritime security strategy is 'Safe and Affluent Sea' and the way to realize the goal is the principle of cooperative leverage, and the means as tasks to implement the strategic concept are maritime safety, maritime security, and maritime stewardship. The concept of national fleet as used in the US is applied to promoting the cooperation between the ROK Navy and Coast Guard. Thus, under the newly-established maritime security strategic concept along with the national fleet model, followings are suggested as policy proposals for facilitating mutual cooperation between the ROK Navy and Coast Guard in dealing with not only traditional threats but also non-traditional treats at sea and from the sea as well. First, the ROK Navy and Coast Guard has been making efforts to enhance interoperability between the two sea services. However, the mutual cooperations have been focused mainly on areas on operational level rather than policy level. Therefore, the two sea services are recommended to enlarge exchanges and cooperation in policy areas. Second, there are still demands for further cooperation areas between the two sea services in command and communications. The interoperability in C2 between the two needs to be upgraded even to the areas of anti-terrorist activities ar sea, ASUW, ASW, maritime interdiction, etc. Third, mutual comparability between the two needs to be reflected in the maritime forces development to ensure the comparability in UNREP and other logistics areas. Fourth, the standardization of logistical materials and equipments is needed as a way of sustaining operational capability and logistical capacity for the ROK Navy and Coast Guard as well. Fifth, the ROK Navy and Coast Guard are recommended to participate more actively in international maritime cooperation activities such as PASSEX. Sixth, Complementary laws and regulations need further to be revised and to be newly made for collectively managing swiftly maritime accidents and natural disasters at sea.

Background: Cervical cancer is relatively common in Thai women, but the proportion of females receiving Pap smear screening is still low. Objective: The purpose of this cross-sectional study was to study factors related to cervical cancer screening uptake by Hmong hilltribe women in Lomkao District, Phetchabun Province. Materials and Methods: Interview data were collected from 547 of these women aged 30-60 years living in the study area and analyzed using multiple logistic regression. Results: The results showed that 64.9% of the study sample had received screening, and that 47.2% had attended due to a cervical screening campaign. The most common reason given for not receiving screening was lack of time (21.4%). The factors found to be positively associated with uptake (p value <0.05) were as follows: number of years of school attendance (OR=1.56, 95%CI:1.02-2.38), animistic religious beliefs (OR=0.55, 95%CI:0.33-0.91), a previous pregnancy (OR=6.20, 95%CI:1.36-28.35), receipt of information about cervical cancer screening (OR=2.25, 95%CI:1.35-3.76), and perceived risk of developing cervical cancer (OR=1.83, 95%CI:1.25-2.67). Conclusions: To promote the uptake of cervical screening, Hmong hilltribe women need to know more about cervical cancer and cervical cancer screening, and access to screening services should be provided in conjunction with existing everyday services, such as family planning and routine blood pressure monitoring or diabetes services.

The Health care program in Korea has now been systemized after 30 years of declaring the inauguration of the national health insurance system by the current government. The national health care covering all Korean citizens was achieved after 12 years of implementing the national health insurance and the health care program since 1977. Hundreds of multiple operational agencies managing the insured individually had undergone the amalgamation process from 1998 to 2000, and had been restructured as one agency, the National Health Insurance Corporation. In 2003, the community/area based financial management was also merged together with the employment based financial management. The National health care system of Korea offer various merits, compared with that of other countries, such as health care provision covering all Koreans, low insurance premium, accessibility of medical services/facilities etc. However, there are still some weak features which need to be addressed for improvement; below expectation insurance cover system, mistrust on the medical services, low medical charges resulted from excessive restrictions, and unstable financial status of the national health insurance etc. Therefore, the National health care system should continue to evolve to re-establish itself as more effective national health care system by further strengthening its merits, and by improving its weaknesses; with adopting the positive system to optimize the costs of prescribed medicines/drugs, applying simpler insurance coverage system to calculate the optimum medical charges, promoting private medical insurances, and increasing insurance premium etc.

Since finance companies started e-banking services, those services have been diversified and use of them has continued to increase. Finance companies are implementing financial security policy for safe e-banking services, but e-Banking incidents are continuing to increase and becoming more intelligent. Along with the rise of internet banks and boosting Fintech industry, financial supervisory institutes are not only promoting user convenience through improving e-banking regulations such as enforcing Non-face-to-face real name verification policy and abrogating mandatory use of public key certificate or OTP(One time Password) for e-banking transactions, but also recommending the prevention of illegal money transfer incidents through upgrading FDS(Fraud Detection System). In this study, we assessed a blacklist based auto detection method suitable for overall situations for finance company, a real-time based suspicious transaction detection method linking with blacklist statistics model by each security level, and an alternative FDS model responding to typical transaction patterns of which information were collected from previous e-Banking incidents.

This study aims to provide basic data for designing aged care residential facilities in Korea, based on the investigation and analysis of the aged care residential services and their communal living areas in Australia focusing on their types, scales, arrangement and the specific design of each compartment. -. A residential building with 10 beds is composed of private zones and communal ones, and their space arrangement depends on how to arrange bedrooms where residents mainly stay. -. A lounge, 26.7 m$^2$ of its average scale, is a main space for daily lives and an important place for making friends with neighboring residents. -. A dining hall is an important area for activity as well as a space for dining. The average scales of dining room, kitchen, and whole space are 42.7 m$^2$, 28 m$^2$, and 70.8 m$^2$ respectively, and those for person are 2.7 m$^2$: 1.7 m$^2$:4.4 m$^2$, although the scales depend on facilities. -. An activity room is used for promoting the social relationship between residents and visitors. Three of the investigated facilities have big rooms of 42 m$^2$, 39 m$^2$ and 51 m$^2$. -. If there is no lavatory in a bedroom, 2-6 bathrooms for residents are arranged near bedrooms and they are relatively big including shower baths. If there is a lavatory in a bedroom, 1 toilet for visitors is arranged in a communal living area and its scale is small.
