The cloud storage has the client lend and use the device as a form of service rather than owning it, and thus the client pays the charge for the service that he or she actually uses, making it beneficial over the self-managed data center. When the storage service is provided on public cloud, however, the clients does not have any control over the user data, which brings a problem of violating data confidentiality. In this paper, we propose a gateway that works between the public cloud and the client for the purpose of guaranteeing the confidentiality of user data stored in cloud. The gateway encrypts or decrypts, and then delivers the user data without the client's intervention. In addition, it provides the function of exchanging keys to allow the client to access through another gateway. The proposed idea has been tested on a commercial public cloud and verified to satisfy security and compatibility.

Most public library websites provide unstructured cultural program data, which cannot be produced and utilized systematically as bibliographic information. It is not sufficiently used in existing library big data research or cases, and there is a risk of disappearing when the website is reorganized or the person in charge is changed. This study developed a data schema that can be used in conjunction with bibliographic data by collecting and analyzing cultural programs and community service data produced in an unstructured manner and proposed to share and utilize public library cultural programs and community service data, and establish a library big data platform that can serve as an information channel between librarians who are cultural program planners. Library program data posted on the library website can be integrated and managed through the platform, securing continuity of work, and systematically managing and preserving the specialized service history of individual libraries.

Purpose: The purpose of this study is to investigate the COVID-19 pandemic-driven effect changes of quality factors on customer satisfaction in Korean Police Civil Affairs Service. Methods: This study fitted a regression model to the data collected by Korean National Police Agency from 2019 (before COVID-19 pandemic) to 2020 (during COVID-19 pandemic). In order to simultaneously estimate the effects of major seven quality factors on customer satisfaction for 'before the pandemic' and for 'during the pandemic', the regression model included not only customer satisfaction as the dependent variable, but also the fourteen independent variables consisting of the seven quality factors and their seven interaction terms. The interaction terms were defined by multiplying each quality factor by a dummy variable indicating either before or during the pandemic. Therefore, the coefficient estimates of the interaction terms indicate the changes of their corresponding quality factor effects on customer satisfaction between before and during the pandemic. The double bootstrap method was applied to test the significance of coefficient estimates. Results: Both before and during the pandemic, all quality factors had positive effects on customer satisfaction. However, these effects changed differently from before to during the pandemic: (increased) supportability, sincerity, and convenience; (decreased) integrity, professionalism, and fairness; (unchanged) promptness. Conclusion: This study found that the pandemic caused significant effect changes of quality factors on customer satisfaction in Korean Police Civil Affairs Service. This finding suggests the necessity of carefully monitoring such effect changes to effectively and efficiently improve customer satisfaction. This study also identified that from before to during the pandemic, supportability, sincerity, and convenience become more important and hence, need to be better managed.

Recently, the importance of IPTV providing multimedia service over IP based networks managed to provide the required level of quality of service and experience, security, interactivity and reliability has been gradually increasing by the commercialization of its service. However, the original purposes of IPTV service - contents are produced and consumed anytime, anywhere, and over any device at the same time - have not been satisfied by service providers because most services offered by service providers depend on closed IPTV platform. In this paper, we propose an open IPTV service platform that an individual or small company can easily produce contents and offer IPTV service independently from the existing closed IPTV platform.. The proposed IPTV platform exploits overlay multicast scheme to offer reasonable service under the environment where network bandwidth and processor resource are limited. It also uses CDN-like scheme to ensure the quality of transmitted contents. The performance evaluation shows that the proposed IPTV platform has the possibility of being an open IPTV platform considering its results such as the quality of transmitted contents, the transmission rate, the channel zapping time, and so on. It also shows that proposed IPTV platform could be applied to real IPTV service with continuous enhancement of its functions and user interfaces.

The purpose of this study is to classify the quality attributes of service quality for the elderly in public libraries, derive satisfaction coefficients and dissatisfaction coefficients, and present the priority improvement of service quality. To this end, a survey was organized with 22 questions from LibQUAL+ for elderly users who use library in uiseong-gun, gyeongsangbuk-do. Quality factors for service were classified into three areas of LibQUAL+ based on the kano model, and the satisfaction index and dissatisfaction index felt by users for each service quality were calculated through timko's customer satisfaction coefficient. Based on this, a Potential Customer Satisfaction Improvement index (PCSI index) was obtained to determine how much user satisfaction can be improved when actual requirements are met. As a result of classification of quality attributes of service quality, it was classified into 9 attractive quality, 7 one-dimensional quality, 1 indifference quality, and 5 must-be quality. In the improvement ranking for service, the first place was 'making electronic resources accessible from my home or office', the second place was 'print and/or electronic journal collections I require for my work' and the third place was 'a library web site enabling me to locate information on my'. It is expected that the study results can be used to present quality factors that should be managed and improved first when providing services for the elderly.

The purposes of this study was to analyze the operational difference of foodservice center for homebound elderly by the presence of the dietitian. The questionnaire was developed to measure all variables for menu management and distributed to 103 meal service centers in charge of congregate meal service program and 57 centers for home-delivered meal service program. The data of 160 centers in charge of congregate meal service and home-delivered service centers were usable for analysis. Statistical data analysis was completed using the SAS 8.1 package program for descriptive analysis and chi-square test. Only 21.9% meal service centers had dietitians, what is more, they were not professionals who did menu management but foodservice managers, volunteers, cook or social workers. The current foodservice programs for the homebound elderly were operated without professional. In the part of menu managemet, dietitians were more actively involved in menu planning in the elderly foodservice center in the presence of the dietitians. The performance level of healthcare service was not significantly different, but the nutrition education in the elderly foodservice center with the dietitians was more frequently performed than that without the dietitians(p<0.05). In the food purchasing and food production management, the significant differences were shown that in the elderly foodservice centers in the presence of the dietitians, the proportion of the contract purchasing was significantly higher than that of direct purchasing(p<0.01). In food sanitary management, the significant differences were not shown in the part of management of keeping meal for identifying the cause of food-borne illness and left-over, but the sanitation education for the foodservice employees was performed more frequently by the presence of the dietitians(p<0.01). In conclusion, the foodservice management was more systematically conducted in the elderly foodservice centers in the presence of the dietitians than that without dietitians. The elderly foodservice program has offered the health-related support for homebound elderly. Although there were several problems in elderly foodservice management, the program delivered well-targeted, effective, and efficient nutrition services and wide range of supportive service to the at-risk older population. It needs to be managed by professional for the improvement in the elderly foodservice.

Recently, the various types of data are began to increase. In order to manage the data efficiently, a variety of cloud services are being made. However, while providing a cloud service, the problem is the cost and waste a lot of human power to manage the data that is generated and managed by the server. To solve this problem, it is build the cloud environment using a single board computer with Raspberry pi. In this paper, we used Raspberry pi as a cloud server to provide services for the users. And we construct a Total Server to manage the generated data. It can separate the processing of data and the provision of services. We ensure the efficient operation by building a cloud environment with Raspberry pi and by managing the data which generated in cloud environment with the total server.

Security threats are increasing with interest due to the mass spread of smart devices, and vulnerabilities in developed applications are being exposed while mobile malicious codes are spreading. The government and companies provide various applications for the public, and for reliability and security of applications, security checks are required during application development. In this paper, among the security threats that can occur in the mobile service environment, we set up the vulnerability analysis items to respond to security threats when developing Android-based applications. Based on the set analysis items, vulnerability analysis was performed by examining three applications of public institutions and private companies currently operating as mobile applications. As a result of application security checks used by three public institutions and companies, authority management and open module stability management were well managed. However, it was confirmed that many security vulnerabilities were found in input value verification, outside transmit data management, and data management. It is believed that it will contribute to improving the safety of mobile applications through the case of vulnerability analysis for Android application security.
