Purpose: The purpose of this study is to assess appropriateness of current standard for insurance coverage by Health Insurance Review & Assessment Service (HIRA) on chemotherapy used in the treatment of advanced non-small cell lung cancer (NSCLC), by reviewing a variety of clinical evidences, and thereby, if needed, to propose an updated evidence-based recommendations. Methods: We collected data from HIRA regarding on the insurance standard which includes the scope and conditions for coverage on systemic chemotherapy of NSCLC. We performed a search for clinical databases and examined the most current clinical evidence from clinical literature including various clinical practice guidelines. Based on the collected data the appropriateness of HIRA standard for insurance coverage of chemotherapy of NSCLC was assessed. Results: Collected data demonstrated that HIRA standard did not reflect the most current clinical practice and evidence. Some were inappropriately listed in HIRA formulary and accepted as a chemotherapy being covered by insurance, despite the lack of evidences of clinical efficacy or superiority over other chemotherapeutic agents or regimens. In addition, there seems to be a need for a modification on the standard for insurance coverage of certain newer chemotherapeutic agents based on the current accumulated data showing their clinical efficacy and benefits in the selected group of NSCLC patients. Therefore, we concluded that current HIRA standard for insurance coverage on chemotherapy of NSCLC needs to be revised and we proposed an updated recommendation based on these latest clinical evidences. Conclusion: The standard for insurance coverage of chemotherapy should be continually examined its appropriateness based on the most recent clinical evidences in a timely manner so as to provide the most effective and safe therapy to cancer patients.

Recently, the digital television transition from analog television to digital television has been progressing in terrestrial broadcasting. As a result of the DTV transition, additional reassignments and deployments of TV White spaces (TVWS) caused by co-channel interference (CCI) were needed. In this paper, we investigate the TVWS caused by CCI using Longley-Rice and ITU-R P.1546 propagation model, which are the most widely-used propagation model. In addition, we analyze the service coverage radius and CCI radius according to the height of transmitter antenna and transmitting power. The results show that the ratios of CCI radius to service coverage radius in Longley-Rice and ITU-R P.1546 propagation model are about 2.54 and 2.07, respectively.

In this paper, we propose cost-effective device-to-device (D2D) advertisement scenario with properties of proximity and timeliness through the convergence of D2D communications and social commerce service. We numerically analyze advertisement dissemination effect of the proposed scenario according to the number of sectors, and demonstrate the performance of the normalized D2D coverage, the average number of D2D users, and the average D2D coverage per user via intensive simulations. We verify the accuracy of the results for our numerical analysis compared with the simulation results.

Background: The purpose of this study was to analyze the effect of national health insurance coverage of Chuna therapy in April 2019 on the costs and service uses in automobile insurance. Methods: This study used the claim data from Health Insurance Review and Assessment Service. A total of 189,912 inpatients and 1,550,497 outpatients who received Chuna therapy covered by automobile insurance in oriental medical institutions were included. The analysis period was from July 2018 to December 2019, and a total of 18 months before and after April 2019, when Chuna therapy was covered by national health insurance. Interrupted time series analysis was applied to analyze the impact on the costs and service uses of Chuna therapy in automobile insurance before and after April 2019. Results: From July 2018 to December 2019, for 189,912 inpatients the cost and the number of times for Chuna therapy per capita were increased by 22.0% and decreased by 7.3% respectively right after the implementation of the policy. In the case of 1,550,497 outpatients, the cost of Chuna therapy per capita tends to be increased by 0.4% in overall study periods and increased 28.4% immediately after the implementation of the policy. Meanwhile, the number of times and visits for Chuna therapy per capita tends to be increased by 0.4% in overall study periods but decreased by 0.4% after the implementation of the policy. Conclusion: Results suggest that if the national health insurance coverage of oriental medicine services increases according to the policy stance for benefit expansion in national health insurance, the criteria for providing national health insurance benefits should be considered with the comprehensive impacts on the costs and service uses of automobile insurance.

The hierarchical covering location problem emphasizes the issue of locating of hierarchical facilities in order to maximize the number of customers that can be covered. In the classical HCLP(Hierarchical Covering Location Problem), it is assumed that the customers are covered completely if they are located within a specific distance from the facility, and not covered otherwise. The generalized HCLP is introduced that the coverage of customers is measured to be any real value rather than 0 or 1, where the service level may decrease according to the distance. Mixed integer programming formulation for the generalized HCLP is suggested with a partial coverage of service. Solutions are found using OPL Studio, and are evaluated for various cases.

Korea government decided to provide the NDGSP service and the conceptional design report are presented here. The coverage of the exiting MDGPS stations of inland area is measured and the positions and characteristics of additional inland NDGPS sites are proposed for the full-coverage of inland areas of Korea.

The DGPS systems that is a GPS augmentation system were installed for ocean- and land-service. The ocean-based reference station of 11 site and the land-based reference station of 6 sites are operating for ocean- and land-service. Although the land-based reference stations provide the output power of 500W, the service shadow regions are occurred due to mountain lands and building area. In this paper, the service coverages for land-based reference stations are analyzed in conditions of output power enhancements of reference station. The service shadow areas are deduced from service coverages of land-based reference stations and ocean-based reference stations. The medium frequency-band wave propagation models are considered as DGPS wave propagation model. The service coverages are analyzed by considering the compensated ground surface-conductivity.

This Paper is to find out a solution for the full-coverage algorithm requiring the real-time processing such as mobile home service robots and vacuum cleaner robots. Previous methods are used by adopting based grid approach method. They used lots of sensors, a high speed CPU, expensive ranger sensors and huge memory. Besides, most full-coverage algorithms should have a map before obstacle avoidance. However, if a robot able to recognize the tangent vector of obstacles, it is able to bring the same result with less sensors and simplified hardware. Therefore, this study suggests a topological based approach and a local obstacle voidance method using a few of PSD sensors and ultra sonic sensors. The simulation results are presented to prove its applicability.
