Digital Science's Dimensions is envisaged as a next-generation research and discovery platform for more efficient access to cross-referenced scholarly publications, grants, patents, and clinical trials. As a new addition to the growing open citation resources, it offers opportunities that may benefit a wide variety of stakeholders of scientific publications, from researchers and policy makers to the general public. In this article, we explore and demonstrate some of the practical potentials in terms of cascading citation expansions. Given a set of publications, the cascading citation expansion process can be iteratively applied to a set of articles so as to extend the coverage to more and more relevant articles through citation links. Although the conceptual origin can be traced back to Garfield's citation indexing, it has been largely limited, until recently, to the few who have unrestricted access to a citation database that is large enough to sustain such iterative expansions. Building on the open application program interface of Dimensions, we integrate cascading citation expansion functions in CiteSpace and demonstrate how one may benefit from these new capabilities. In conclusion, cascading citation expansion has the potential to improve our understanding of the structure and dynamics of scientific knowledge.

Moon Jae-in Government announced the Government's 5-Year Plan on July 19, 2017, President Moon directly announced the Government's Plan for Benefit Expansion in National Health Insurance on August 7, 2017. The main contents of the announced expansion include benefit coverage for all medically necessary services with control over non-covered service occurrence, a decrease in the cost-sharing upper limit, and monetary support for catastrophic medical costs. Although past governments have been continuously striving for benefit expansion in the last 15 years, this plan has its breakthrough aspect in that all medical services will be covered by the National Health Insurance. In alignment, there are important tasks to solve: attaining a proper fee schedule, reforming the healthcare delivery system, and improving healthcare quality. This plan is a symptom oriented action in that it is limited in reducing patients' out-of-pocket money, unlike the systematic approach of the National Health Insurance. The sustainability of the National Health Insurance is being threatened due to South Korea's low birth rate, rapidly aging society, and low economic growth, in addition to the unification issue of the Korean Peninsula, medical utilization of the elderly, management of non-communicable diseases, and so on. Therefore, the Government needs to plan the National Health Insurance system reformation including actions addressed toward medical consumers.

National Immunization Program (NIP) in korea is regulated by government for effective prevention of infectious diseases since 1954. But the program is only performed in public health center, so many people had various complaints such as inconvenience to use public center, high cost when vaccinated in private medical organization and lack of speciality and registration etc. In this reason, it was very difficult to raise the vaccination rate to 95 percent, infectious disease preventable rate. With this background national assembly and government try to expand the NIP coverage both public health center and private medical organization with increasing budget from 2009. So in this paper an overview and preparation of Korean pediatrician according to the expanding plan of NIP are described.

The crossing Y-stent method is one of the indispensable techniques to achieve sufficient neck coverage during coil embolization of bifurcation aneurysms with a wide neck and/or branch incorporation. However, the inevitable hourglass-like expansion of the second stent at the crossing point can result in insufficient vessel wall apposition, reduced aneurysm neck coverage, delayed endothelialization, and subsequent higher risks of acute or delayed thrombosis. It also interferes with engagement of the microcatheter into the aneurysm after stent installation. We expected to be able to reduce these disadvantages by installing a noncrossing type Y-stent using the Solitaire AB stent, which is fully retrievable with a tapered proximal end. Here we report the techniques and two successful cases.

Objectives: This study aimed to investigate the opinions of Korean medical doctors on how to elucidate possible remedial measures for expanding the health insurance benefits coverage item of Korean medicine (KM). Methods: An online survey was conducted to all members who had registered e-mail address in the association of Korean medicine from 1 to 17 November, 2016. Statistical analysis was performed and odds ratio with 95% confidence interval were calculated by each subgroup. Results: A total of 743 members answered the questions and the response rate was 4.1%. The priorities for expanding health insurance benefits were as follows: thermographic imaging, Sasang constitution typing test, and pulse wave among examinations; pharamacopuncture, embedding acupuncture, and acupotomy among procedures; Chuna manual therapy, manual therapy for meridian muscle, and Daoyin exercise therapy among manual therapies; low-frequency electrical therapy, traction, paraffin bath, and light therapy among physical therapies; and aromatherapy, enema therapy, and color therapy among activities of KM. Conclusions: It should be covered by the national health insurance (NHI) of KM that thermographic imaging, pharmacoacupuncture, Chuna manual therapy, low-frequency electrical therapy, aromatherapy as a top priority. We also suggest that basic medical tests, such as blood, urine, or imaging, should be included in the coverage of the NHI of KM. It is necessary to review the expertise and public opinions about the plans and priorities for the conversion of the desired medical services to be covered by the NHI.

Small cell networks, as an important evolution path for next-generation cellular networks, have drawn much attention. Different from the traditional base stations (BSs) always-on model, we proposed a BSs on-off model, where a new, simple expression for the probabilities of active BSs in a heterogeneous network is derived. This model is more suitable for application in practical networks. Based on this, we develop an analytical framework for the performance evaluation of small cell networks, adopting stochastic geometry theory. We derive the system coverage probability; average energy efficiency (AEE) and average uplink power consumption (AUPC) for different association strategies; maximum biased received power (MaBRP); and minimum association distance (MiAD). It is analytically shown that MaBRP is beneficial for coverage but will have some loss in energy saving. On the contrary, MiAD is not advocated from the point of coverage but is more energy efficient. The simulation results show that the use of range expansion in MaBRP helps to save energy but that this is not so in MiAD. Furthermore, we can achieve an optimal AEE by establishing an appropriate density of small cells.

In the process of promoting policies to strengthen health insurance coverage, the relationship between public health insurance and private health insurance, along with the management of non-benefit, is also emphasized as a policy issue. First, the concept and scope of non-benefit were comparatively analyzed by country. Second, the interaction between the public and private health insurance was classified as 'large or small,' and the government's regulation and management policy on private health insurance was classified as 'strong or weak.' Korea has relatively smaller benefits covered by public health insurance, higher copayment expenses, and more areas and scope of non-benefits. In countries where the interaction between public and private health insurance is small, private health insurance-related policies are weak. And in countries with large interactions had public-private partnerships and the government's management policies were also strong. On the other hand, Korea has a large interaction, but the actual structure of cooperation between public and private insurance and management policies were weak. Because the non-benefit sector in Korea is relatively wide, it is difficult to manage compared to other countries where the concept of non-benefit is limited. In addition, the health authorities rarely perform the role of supervision over private health insurance, and they have so few linkages and cooperation for public-private insurance. Therefore, practical policy enforcement is necessary to achieve the easing of the burden of national medical expenses through linkage and cooperation of public-private health insurance with reference to relevant other countries' cases.
