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.

Cloud computing offers a platform that is both adaptable and scalable, making it ideal for outsourcing data for sharing. Various organizations outsource their data on cloud storage servers for availing management and sharing services. When the organizations outsource the data, they lose direct control on the data. This raises the privacy and security concerns. Cryptographic encryption methods can secure the data from the intruders as well as cloud service providers. Data owners may also specify access control policies such that only the users, who satisfy the policies, can access the data. Attribute based access control techniques are more suitable for the cloud environment as they cover large number of users coming from various domains. Multi-authority attribute-based encryption (MA-ABE) technique is one of the propitious attribute based access control technique, which allows data owner to enforce access policies on encrypted data. The main aim of this paper is to comprehensively survey various state-of-the-art MA-ABE schemes to explore different features such as attribute and key management techniques, access policy structure and its expressiveness, revocation of access rights, policy updating techniques, privacy preservation techniques, fast decryption and computation outsourcing, proxy re-encryption etc. Moreover, the paper presents feature-wise comparison of all the pertinent schemes in the field. Finally, some research challenges and directions are summarized that need to be addressed in near future.

The third party logistics(3PL) is generally understood as the logistics activities providing a comprehensive logistics services, all or partly outsourced by the customers on a larger term contract basis, ranging from making logistics strategies to implementing information technology services. A lot of companies in advanced countries such as the U.S.A. or some of the European countries have actively outsourced to logistics service providers in efforts to increase the efficiencies in logistics operation rather than doing themselves. In light of these environments, outsourcing to third parties has become a strategic issue demanding greater attention in corporate boardrooms. First, after deciding their logistics outsourcing, the companies have to set up their aims of 3PL through the development of logistical strategies. Second, the companies must decide service provider that fits to their business environment and conditions. As it is reported that 3PL services will bring a high rate of return and its potential will be more signigicant, providers and users of 3PL services and government ministry should prepare the way of improvement of logistics institution and plan to activate 3PL services to reach the advanced foreign countries level.

Recently, many companies have been very interested in CRM(Customer Relationship Management). Most companies have been also considering the contact center as a key CRM channel, because it is a contact point between customers and companies. It turns out that the contact center handles over 70% of all customer-company interactions and the success or failure of a company can be determined by the customer satisfaction with contact center experiences. Despite of the strategic importance of the contact center, there has been few empirical study on the efficiency of contact center operations in the literature. One of the main purposes of this study is to evaluate the efficiency of contact centers so as to not only identify the current status of contact center operations, but also suggest ways to improve operational efficiency. For this purpose, we apply a non-parametric efficiency measurement method, DEA (Data Envelopment Analysis), to 57 domestic contact centers in order to compare their relative efficiency. It is expected that the measurement methods suggested in this study can be applied to various issues such as service KS certification, outsourcing service management, and the productivity analysis of service personnel.

Objectives: The study aims to compare indirect form of employment with direct form of employment on the variables of occupational danger and physical health. Methods: I studied based on the data of 5th Korean Working Conditions Survey (KWCS) which was performed by Occupational Safety & Health Research Institute of Korea Occupational Safety and Health Agency in 2017. SAS 9.4 was used for statistical analysis of the final data. Results: Based on the verification result, the hazard is higher for direct employment than for dispatch or subcontract in case of exposure to risks in the health and social welfare industry. Based on cross tabulation, significant differences were found in the proportions of harmful and safe tasks in direct employment and those in outsourcing in the physical health industry. It was found that the risk of hazard is 2.18 times higher in outsourcing jobs than in direct employment. Conclusions: It is necessary to consider a dispatch and subcontract partner as a strategic partner and not simply hand over dangerous or hard tasks to them. Active and aggressive cooperation along with support from the employer enterprise built in the contract is necessary for the safety and health of dispatch or subcontract laborers.
