In late 90s, organizations recognized the information technology as an key enabler of the business strategic accomplishment which lead them heavy increment on IT investment. These organizations tried to hold the competitive advantage by focusing on their core competency. And these acts raise their interests on IT outsourcing. Recent trends of the organizations concern on evaluating the effectiveness of the previous IT investment and the reasonable selection on IT investment type. Also, the objective evaluation of the service level and continuous improvement are major concern of the outsourcer. Consequently, 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 provider and an outsourcer, the agreement is treated with high confidentiality. This raised the problems to both the private and public organizations, are considering the SLA, with absence of concrete guide line to internalize SLA management process. This study provides the organizational and environmental factors of the adopting and applying the Service Level Agreement (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 operational contribution for implementing the SLA. The study also provides the effects on IT performance through the SLA. For this, in depth interview was conducted for each sampled company. As a result, if SLA between outsourcer and service provider can be used as an immanence operation tool and actively implemented, SLA will be an strategic tool for various decision making in IT management practice with long term relationship, better shared partnership, and continuous service improvement.

Outsourcing enables firms to use external resources in efficient and effective manner by adopting the best practice of industry. It also helps firms improve their business process which may result in seizing or creating new business opportunity. Collaborating with outstanding BPO(business process outsourcing) providers offer a great deal of advantage that could access to new knowledge, technology, intellectual and material resources that firms do not own. This study was designed to provide in-dept understanding of key elements that may affect the attitude towards BPO of entrepreneurs using 99 samples comprised SME & Venture business owners. Specifically, this study aims to test and analyse the relationship between attitude towards BPO and 4 independent variables including cost reduction, core competence, specialized resources and quality improvement. The analysis results show that core competence, specialized resources and quality improvements have all positive relationships with the attitude towards BPO. However, exceptionally cost reduction is not associated positively with the attitude towards BPO which was against our expectation. Theoretical discussion and practical implication on the analysis results are provided.

Recently, research on database encryption for data protection and query result authentication methods has been performed more actively in the database outsourcing environment. Existing database encryption schemes are vulnerable to order matching and counting attack of intruders who have background knowledge of the original database domain. Existing query result integrity auditing methods suffer from the transmission overhead of verification object. To resolve these problems, we propose a group-order preserving encryption index and a query result authentication method based on the encryption index. Our group-order preserving encryption index groups the original data for data encryption and support query processing without data decryption. We generate group ids by using the Hilbert-curve so that we can protect the group information while processing a query. Finally, our periodic function based data grouping and query result authentication scheme can reduce the data size of the query result verification. Through performance evaluation, we show that our method achieves better performance than an existing bucket-based verification scheme, it is 1.6 times faster in terms of query processing time and produces verification data that is 20 times smaller.

Recently, it's a trend that the third party outsourcing logistics will be increased a logistics flow from law material to final products. The government also works on promoting logistics company as securing the expertise for strengthen logistics industry and secure competitiveness. Nevertheless, logistics market have been divided by polarization between small logistics company and major company. Also a labor who work for logistics is being caused by worsened working conditions. That is one of results of the survey. Almost 50% of response are they have not been aware of FTA and have not known to need the FTA. Many respondents said that entering the overseas logistics or a new way like FTA will be difficult to take part in. Therefore I suggest several examples in this paper to encourage a vitalization of small logistics company through the multilateral FTA. Now our country needs to make an effort to maximize connections between multilateral FTA and policy effect by signing FTA with many countries and extending Economic territory. This effect can completely cope with the improvement of economic interests, establishing regional integration strategy and change of global supply chain. Therefore, a small business logistics have to make their competitiveness & a new dealing market in the future.

Background: The series of serious industrial accidents in recent years at contractors to large companies has highlighted risk outsourcing as a real and urgent problem. This study aims to review the difference in the degree of risk exposure and the occurrence of industrial accidents depending on the type of company relations. Among in-house contractors, the focus will be on those handling hazardous chemicals that include companies for which outsourcing requires approval. Methods: This study uses the 9th wave of the Industrial Safety and Health Survey (2018). For determining the degree of risk exposure, the occurrence of industrial accidents, and industrial accident rate, multivariate, logistic, and fractional logit, regression analyses were used, respectively. Results: First, In-house contractors' degree of risk exposure is higher than that of the client companies. In particular, this gap is even greater for companies dealing with chemicals. Second, among only those that handle hazardous chemicals, in-house contractors do show a significantly higher rate of industrial accident occurrence. Third, In-house contractors have a significantly higher rate of industrial accidents from diseases than client companies. Conclusion: The analysis supports the intent of the legal amendment that strengthens the protection of in-house contracted workers who handle hazardous chemicals. Second, the results of this study suggest that safety and health management must go beyond legal compliance and ensure that it has substance and effectiveness. Last, there should be policy consideration is necessary to reduce attempts to hide industrial accidents.

The study focused on the evaluation of maintenance management strategies used in public hospital buildings in Lagos state. It also assessed the labour composition for maintenance operations. In achieving these objectives, opinions of maintenance officers of ten (10) different hospitals in different local government areas of the state were sampled through well structured questionnaires. The data collected were analyzed using descriptive and inferential statistics. From the analysis, the study revealed that majority of those public hospitals do not have specific budget for maintenance programmes, maintenance policies, maintenance log book and maintenance manual to guide the operatives. About 98% of them do not understand the type of maintenance strategy being used for their maintenance operations. 78% of the maintenance work are only executed when there is a breakdown or in response to user's request. For labour composition, the cleaning of interior and exterior of the building, inspection of building elements, repairs and replacements of building elements are mainly carried out by in-house staff, while the repair and replacement of equipment is by outsourcing. The study also revealed that using in- house staff, reduces costs and provides a higher security while outsourcing provides more flexibility in staffing reduces equipment expenditures and provide better access to special skills. The study recommended proactive measures to provide necessary training and support for maintenance staff and users of these facilities and a means of securing sufficient funds for maintenance programmes.

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.

ASP service that is emerging as a new form of application outsourcing has the advantage of lower cost and risk. Therefore, ASP service may be attractive for small firms and even some new companies. However, studies about ASP service are rare in academic and professional journals, and most of the articles about outsourcing were considering mainly large enterprises. The purpose of this article is to analyze the effects of the some context variables of Korean small businesses on ASP service usage pattern, and the effect of ASP service usage pattern on user satisfaction and firm performance. The analysis results show that firm size has a positive impact on IT need of small businesses, and IT need of small businesses have a positive impact on training period and past usage period. Also, firm size, IT need, training period has an positive impact on ASP service usage pattern. However, ASP service usage period has no relationship on ASP service usage pattern. Finally, ASP service usage pattern has a positive impact on firm performance and user satisfaction, and user satisfaction has an impact on firm performance.
