  • The increasing demand in promoting cloud computing in either business or other areas requires more security of a cloud storage system. Traditional cloud storage systems fail to protect data integrity information (DII), when the interactive messages between the client and the data storage server are sniffed. To protect DII and support public verifiability, we propose a data integrity verification scheme by deploying a designated confirmer signature DCS as a building block. The DCS scheme strikes the balance between public verifiable signatures and zero-knowledge proofs which can address disputes between the cloud storage server and any user, whoever acting as a malicious player during the two-round verification. In addition, our verification scheme remains blockless and stateless, which is important in conducting a secure and efficient cryptosystem. We perform security analysis and performance evaluation on our scheme, and compared with the existing schemes, the results show that our scheme is more secure and efficient.

  • The golf industry has become the center of attention for recreational activities in the participant sport market; however, there has been little effort made to understand golf consumer and their consumption behavior using the concept of 'recreational specialization' which segments the golfers based on level of specialization in golf. The purpose of this study was to explore the differences in the relationships among perceived service quality, price of playing golf, overall customer satisfaction with the course, and a player's intention to revisit the same golf course based on the magnitude of recreation specialization in golf. Four public and two private golf courses from the southeastern state of the United States were randomly chosen from a list in a golf magazine. The 365 surveys among 417 participants were ultimately analyzed. Multiple group analysis was conducted in order to investigate differences in relationships among service quality, price, customer satisfaction, and revisit intentions between groups based on the level of recreation specialization. The key findings were 1) for more specialized golfers, satisfaction with price did not affect overall customer satisfaction or revisit intention, however, service quality significantly influenced both overall customer satisfaction and revisit intention, 2) for less specialized golfers, satisfaction with price significantly influenced overall customer satisfaction but did not affect revisit intention. Knowledge about which the determinants of satisfaction are different between more and less specialized golfers could provide a better understanding of how different marketing strategies should be implemented for different specialized levels of golfers.

Research design, data, and methodology - After a meticulous literature review, the researchers administered a two part questionnaire to know the service gaps and satisfaction levels of the customers. The research carried out with a sample of 400 respondents but received only 150 responses from the residents around Adamawa state. The collected data was edited, coded, and analyzed with the SPSS latest version with the descriptive and inferential statistical tools. Results - Majority of the respondents expressed their discontentment over the responsiveness of the service providers when compared to tangibility and reliability quality variables. There is no relationship between the quality variable tangibility and overall satisfaction. Related to the overall satisfaction, 42 percent of respondents have neutral perspective indicated that they are either satisfied or dissatisfied as against the 43.3 percent of dissatisfied customers. Conclusions - This research proffers invaluable information to the entire Nigerian health-care sector to review their existing delivery of services to improve patient satisfaction. This research is first of its kind concentrated to know the quality of health-care services and customers overall satisfaction in Nigeria.

  • In this paper, we define a Hose-NSIS-QoSM, which reserves and manages resources according to the hose based resource provisioning mechanisms for supporting the VPN QoS(Quality of Service) using the NSIS(Next Step in Signaling) signaling protocol. Specifically, we specify the NSIS message objects, the structures of QoS NSLP(NSIS Signaling Layer Protocol)/NTLP(NSIS Transport Layer Protocol)/RMF(Resource Management Function) state tables and the processing of the signaling messages in NSIS nodes. Also, we compare the Hose-NSIS-QoSM with the Hose-RSVP-TE-QoSM that supports the hose based VPN QoS in the MPLS networks using the extended RSVP-TE mechanism.

  • Since 2015, the Health Insurance Review and Assessment Service (HIRA) has performed annual qualitative assessments of asthma management provided by all medical institutions that care for asthma patients in Korea. According to the third report of qualitative assessment of asthma management in 2017, the assessment appears to have contributed to improving the quality of asthma care provided by medical institutions, especially primary clinics. However, there is still a gap between the ideal goals of asthma management and actual health care policies/regulations in real clinical settings, which leads to the state of standstill with respect to the quality of asthma management despite considerable efforts such as the qualitative assessment of asthma management by national agencies such as the HIRA. At this point, a harmonized approach is needed to raise the level of asthma management among several components including medical policies, efforts of academic associations such as education and distribution of the guideline for management, and reliable financial support by the government.

  • The fifth generation (5G) is a state-of-the-art mobile communication access technology that uses sub 6 GHz bands and mmWave. Presently, the 5G network is partially deployed along with 4G in areas with dense traffic. In the future, the demand for the 5G bandwidth may increase. Thus, it is necessary to study the coexistence between the 5G and radio systems using adjacent or same channels to eliminate the interference between radio systems and efficiently utilize the frequency. This paper analyzed the impact of 5G new radio downlink on the fixed-satellite service earth station operating at the co-channel and adjacent channel in the upper 3.7 GHz band using the Spectrum Engineering Advanced Monte Carlo Analysis Tool, which is based on the Monte Carlo method. The results of this paper can be utilized for planning the frequency allocation of 5G networks; they can also be used as a guideline for deploying 5G base stations around a fixed-satellite service earth station.

  • Dielectric breakdown accidents have been mainly occurred in the vicinity of service entrance section in underground power transmission systems. One cause among them is due to the excessive component value of sheath located around service entrance of cable. In this paper, as one of the alternative to prevent these accidents, the change of cross bond grounding system and the location change of IJ(Insulation Joint) are suggested. Also, to evaluate effectiveness of this changing system, circulating current and induced voltage of sheath were analyzed in steady and transient state. By comparison of the analytical results for the several possible changing systems, a grounding system and location of IJ which has the smallest sheath component values is proposed. In this paper, analysis to evaluate the proposed system is carried out by EMTP/ATPDraw. It can be used as a valuable operational material to prevent accident of the service entrance section in underground power transmission system.

  • The mobile communication service is widely used and the repeaters is rapidly increasing because of the extending service areas. we propose a new Signed CMA(: Constant Modulus Algorithm) algorithm for ICS(: Interference Cancellation System) as a larger service area of mobile communication service. The proposed Signed CMA algorithm improved performances by adjusting step size values. We showed that the proposed algorithm could improve the Mean Square Error(: MSE) performance of Signed CMA. MATLAB(: Matrix Laboratory) is employed to analyze the proposed algorithm and to compare it with the experimental results. At the convergence of 1000 iteration state, the MSE(: Mean Square Error) performance of the proposed Signed CMA algorithm with step size of 0.0065 is about 5 dB better than the conventional CMA algorithm.
