대부분의 Web Service는 성능 개선을 위해 사용자 접속 로그를 생성하여 관리한다. 생성된 접속 로그를 통해 트래픽이 많이 발생하는 시간대와 어떤 Resource가 많이 사용되는지 확인할 수 있으며 로그 분석을 통해 Web Service의 성능 측정 및 개선하는데 이용된다. 하지만, 많은 공공부문 Web Service와 같이 일정 기간 동안에 접속량이 증가할 때, 처리 할 사용자 접속 로그 수 증가로 인해 Web Service의 성능이 저하된다. 이를 해결하기 위해, 시스템의 성능을 개선하거나 튜닝을 필요로 하지만 많은 비용이 발생하게 되며 일정한 시간이 지나면, 사용자의 접속이 줄어들게 되어 더 많은 비용이 발생한다. 본 논문에서는 사용자 접속 로그 처리의 성능을 개선을 통한 Web Service의 성능개선을 제안한다. 또한, 최근 대용량 데이터를 처리하기 위하여 많이 사용되고 있는 Redis를 활용하여 NoSQL을 일부 적용한 방법을 제안한다.

It is necessary to systematically explore the reform plans of the Software Industrial Promotion Law to systematically a representative high-added value future knowledge-based industry, software industry. The current Software Industrial Promotion Law provides only one provision on software business contract procedures, and the Civil Code, the National Contract law or Subcontract Fairness Law regulate other things, so the features of software industry are not properly reflected. To the contrary, the Information Communication Construction Law or the Construction Basic Law effectively prevent disputes by providing material and detailed provisions. Therefore the current software industry needs to be shifted from promotion to fundamental one. That is, as the software industry takes up a large portion at present, so the law should have basic procedural provisions. Also the National Contract Law governs only the contract procedures of public sector, so there should be business performance procedural provisions to regulate the software business formalities of civil sector. And the National Contract Law controls the sale, construction and service of articles at separate contract procedures, but software business contains construction and service characters simultaneously, so there should be business performance procedures fit for software business. Thus this study presented the legislative need and bill on the performance procedures of software business.

Information Centric Networking that uses content name instead of IP address as routing identifier can handle challenges such as traffic explosion and user mobility, but it also suffers from scalability and incompatibility problems. In this paper by combining the concept of software defined networking and Internet end to end arguments, we propose a wide area deployable software defined information centric networking service model named SD-ICN. SD-ICN employs a dual space structure that separates edge service network and core transmission network. The enhanced SDN techniques are used in edge service network in order to implement intelligent data routing and caching, while traditional IP technique is reserved in core transmission network so as to provide wide area high speed data transmission. Besides, a distributed name resolution system based on the cooperation of different controllers is also presented. The prototype experiments in our campus network show that SD-ICN can be deployed in a scalable and incremental way with no modification of the core network, and can support typical communication modes such as multicast, mobility, multihoming, load balancing, and multipath data transmission effectively.

In these days companies are rapidly implementing the extended enterprise collaboration to provide enhanced management services and products based on the enterprise integration that human resources, technologies and the management process. In this corporate environment, ASP (Application Service Provider) which is the developed type of outsourcing in the area of information technology, is a good alternative for corporate information system management. ASP defines as a software leasing service which is supplied through networks instead of purchasing application software with high price. For successful implementation of ASP, it is necessary to develop the certification methodology to ensure safety and reliability of ASP. The paper provides the safe and reliable certification methodology for ASP. In order to develop it, the critical issues related to service quality and certification of ASP are identified and the systematic certification methodology of application and service provider(service environment) domains of ASP are provided. A evaluation method for the developed certification methodology is also proposed.

For a library to be able provide information services and fulfill its function as a knowledge convergence center capable of responding to various information demands, the development of next-generation information systems based on the latest information and communication technology is needed. The development of mobile information services using portable devices such smart phones and tablet PCs and information systems which incorporate the concepts of cloud computing, SaaS (Software as a Service), annotation and Library2.0 is also required. This paper describes a library information system that utilizes collective intelligence and cloud computing. The information system developed for this study adopts the SaaS-based cloud computing service concept to cope with the shift in the mobile service paradigm in libraries and the explosion of electronic data. The strengths of such a conceptual model include the sharing of resources, support of multi-tenants, and the configuration and support of metadata. The user services are provided in the form of software on-demand. To test the performance of the developed system, the efficiency analysis and TTA certification test were conducted. The results of performance tests, It is encouraging that, at least up to 100MB, the job time is approximately linear and with only a moderate overhead of less than one second. The system also passed the level-3 or higher criteria in the certification test, which includes the SaaS maturity, performance and application program functions.

Recently the information system introduction and the application which use the computer are increasing. The efficient operation of information system helps corporations to improve productivity, customer service and corporate competitive power. SaaS(Software as a Service), which is the developed type of outsourcing in the area of information technology, is to use standardized and packaged application by hosting from the outside of enterprise. SaaS is not developed yet as much as people's interest about that in the initial stage, but its related technology and service capacity are accumulated after repeated trial and error, and it's ready to activate the industry. In the area of information system, studies on the measurement of service quality were followed. But there is little study on service quality measurement in the field of SaaS(Software as a Service). The purpose of this study was to divides the SaaS with e-SERVQUAL and it consider the relationship with the perceived recognition and the usage intention. According to this, variables of traditional research were rejected because SaaS is not developed yet in Korea. But information had a strong effect on perceived recognition. Therefore, business related with in SaaS must have provided a correct information about various applications.

Recently, interest in living safety and crime prevention is increasing. The reality is that most women have anxiety about social safety and ultimately want a safe return to home. As a result of these issues, the Seoul Metropolitan Government and the National Police Agency are implementing various services to alleviate them. However, there are limitations such as that the service can be used only during a limited time or the process of checking whether the patrol is really completed is complicated. Therefore, in this paper, we propose a service platform that overcomes these limitations and suggests the best and shortest patrol route to the police based on the desired patrol location applied by citizens. It is designed based on the MVC pattern, and the functions are divided for each user. It is hoped that the platform will reduce crime rates and allow citizens to ultimately return home with peace of mind. Also we expect that the police will ablet to find places where they did not know about or need to patrol with more attention through the recommended route of the platform, which will be helpful in their task.
