The MSIP has implemented "Act on The Development of Cloud Computing and Protection of Its Users" from September 2015 and invigorated the cloud service industry. The act mainly includes the improvement cloud computing reliability and user protection for the development foundation and use activation. In order to expand the cloud market, it is important to increase the reliability of individual users. However, practical discussions and approach for cloud services adoption are still limited. In fact, there is no agreement standard for domestic cloud services. As a user agreement is not standardized, users feel difficulty compare to each agreement of cloud service provider and may be damaged because of unfair terms. Thus, it is necessary to examine the unfairness of cloud service agreement for user protection. This study analyzes domestic and foreign cloud service agreements including Practical Guide to Cloud Service Agreement of Cloud Standards Customer Council and suggests the direction of the standard agreement of cloud services.

Today, due to the serviceization of the economy, volume and position Global trade in Services have gradually increased. Stable and fair trade can be achieved through solid international trade law. Multilateral discussions on service trade agreement have been stagnant, but have recently shown considerable outcome. Service trade agreement(GATS) deal with various service trade barriers in member countries that hinder free trade in services. Recently, a group of WTO members have established the 「Joint Initiative on Services Domestic Regulation」. The agreement aims to ensure that licensing and qualification requirements and procedures, as well as technical standards do not constitute unnecessary barriers to services trade. This study is to understand the type and statistics of service trade barriers that affect actual service transactions. At the same time, It aims to examine the progress of discussions on multilateral service trade agreement for resolving service trade barriers.

The QoS management is an agreement of service user and service provider in B3G networks, and service provider must support proper the network service to service users by the agreement facts. The service provider must provide the QoS method to maintain the agreed service, which manages the detail method of system level from policy level. By the agreement of service policy, the service provider can give the QoS to the service customer with the service agreement. Hence, in this paper we propose a QoS mapping method of heterogeneous networks to provide the customer service through the service agreement based on the SLA of B3G networks.

For the successful IT operation outsourcing there need appropriate metrics on which both of the service clients and provider agree. The metrics are used to set up the service level objectives, which are manifested in the service level agreement with price. A study of metrics is necessary for the following reasons: First, most of the metrics used today were introduced in the early years of computers and are not satisfactory to both of the service providers and clients. Second, metrics represent the performance of system components but not end-user satisfaction. Third, because the service provider leads the outsourcing agreement, the objectives are specified more favorable to the provider. The objectives should be based on metrics that both sides fully understand and agree on.

Interests on Service Level Agreement(SLA), an immanence operating tool for managing the level of the information system service objectively and qualitatively, were raised among IT outsourcing service providers, outsourcers, and operating departments. Yet, only a few domestic conglomerates adopted the SLA, and exact usage of the SLA is currently unknown. Because of the importance of the SLA between a service recipient and a service provider, the agreement is treated with high confidentiality. This raised the problems to organizations which are considering the SLA but lack in the concrete guide line to internalize SLA management process. This study provides the process model of implementation for SLA by conducting multiple case research. The sampled companies are currently implementing the SLA over 1 year of usage period. Factors were used to provide the managerial contribution for implementing the SLA. To analyse the case samples, in-depth interview method was conducted for each sampled company. As a result, if SLA can be used as an immanence managerial tool and can be actively implemented, it will be an strategic tool for various decision making in IT management practice with long term relationship, better shared partnership, and continuous service improvement.

Objectives: The objectives of this study were to investigate the agreement between medical history questionnaire data and claims data and to identify the factors that were associated with discrepancies between these data types. Methods: Data from self-reported questionnaires that assessed an individual's history of hypertension, diabetes mellitus, dyslipidemia, stroke, heart disease, and pulmonary tuberculosis were collected from a general health screening database for 2014. Data for these diseases were collected from a healthcare utilization claims database between 2009 and 2014. Overall agreement, sensitivity, specificity, and kappa values were calculated. Multiple logistic regression analysis was performed to identify factors associated with discrepancies and was adjusted for age, gender, insurance type, insurance contribution, residential area, and comorbidities. Results: Agreement was highest between questionnaire data and claims data based on primary codes up to 1 year before the completion of self-reported questionnaires and was lowest for claims data based on primary and secondary codes up to 5 years before the completion of self-reported questionnaires. When comparing data based on primary codes up to 1 year before the completion of selfreported questionnaires, the overall agreement, sensitivity, specificity, and kappa values ranged from 93.2 to 98.8%, 26.2 to 84.3%, 95.7 to 99.6%, and 0.09 to 0.78, respectively. Agreement was excellent for hypertension and diabetes, fair to good for stroke and heart disease, and poor for pulmonary tuberculosis and dyslipidemia. Women, younger individuals, and employed individuals were most likely to under-report disease. Conclusions: Detailed patient characteristics that had an impact on information bias were identified through the differing levels of agreement.

As demand for IT services increase, which are based on SOA and cloud computing, service level agreements (SLAs) have received more attention in the parties concerned. An SLA is usually a paper contract written in natural language. SLA management tools which are commercially available, implement SLAs implicitly in the application with a procedural language. This makes automation of SLA management difficult. It is also laborious to maintain contract management systems because changes in a contract give rise to extensive modifications in the source code. We see the source of the trouble is the existence of documentary SLAs (paper contracts) and corresponding executable SLAs (contracts coded in the procedural language). In this paper, to resolve the current SLA management problems we propose an active SLM (Active Service Level Management) system, which is based on the active SLA (Active Service Level Agreement). In the proposed system, the separated management and processing of dual SLAs can be unified into a single process with the introduction of active SLAs (ASLAs).

Cloud-based technology is used in different organizations around the world for various purposes. Using this technology, the service providers provide the service mainly SaaS, PaaS and while the cloud service consumer consumes the services by paying for the service they used or accessed by the principle of "pay per use". The customer of the services can get any services being at different places or locations using different machines or electronic devices. Under the conditions of being well organized and having all necessary infrastructures, the services can be accessed suitably. The identified problem in this study is that cloud providers control and monitor the system or tools by ignoring the calculation and consideration of various faults made from the cloud provider side during service delivery. There are currently problems with ignoring the consumer or client during the monitoring and mentoring system for cloud services consumed at the customer or client level by SLA provisions. The new framework was developed to address the above-mentioned problems. The framework was developed as a unified modeling language. Eight basic components are used to develop the framework. For this research, the researcher developed a prototype by using a selected cloud tool to simulate and java programming language to write a code as well as MySQL to store data during SLA. The researcher used different criteria to validate the developed framework i.e. to validate SLA that is concerned with a cloud service provider, validate what happened when the request from the client-side is less than what is specified in SLA and above what is specified in SLA as well as implementing the monitoring mechanism using the developed Monitoring component. The researcher observed that with the 1st and 3rd criteria the service level agreement was violated and this indicated that if the Service level agreement is monitored or managed only by cloud service prover, there is a violation of LSA. Therefore, the researcher recommended that the service level agreement be managed by both cloud service providers and service consumers in the cloud computing environment.

To satisfy SLA(Service Level Agreement) contract between a client and a service provider, the client requests are classified and processed by priorities. In providing differentiated service, a request from a client who has low priority can be dealt with less important. In this paper, we study static and dynamic partitioning mechanism of web servers and also admission control policy for multiclass request distribution. Through simulation experiments, we analyze web server throughput and response time considering SLA.
