In this paper, scale efficiencies and relative efficiencies of R&D projects in Industrial Technology Program, sponsored by Ministry of Trade, Industry and Energy, Korea, are calculated and compared. For the process, various DEA (Data Envelopment Analysis) models are adopted as major techniques. For DEA, two stage input oriented models are utilized for calculating the efficiencies. Next, the calculated efficiencies are grouped according to their subprograms (Industrial Material, IT Fusion, Nano Fusion, Energy Resources, and Resources Technology) and recipient types (Public Enterprise, Large Enterprise, Medium Enterprise, Small Enterprise, Lab., Univ., and etc.) respectively. Then various subprograms and recipient types are compared in terms of scale efficiencies (CCR models) and relative efficiencies (BCC models). In addition, the correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies is calculated, from which the causal relationship between them can be inferred. Statistical analysis shows that the amount of input, in general, should increase in order to be scale efficient (CCR models) regardless of the subprograms and recipient types, that the 1st and 2nd stage relative efficiencies are different in terms of the programs and recipient types (BCC models), and that there is no significant correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies. However, the results should be used only as reference because the goal each and every subprogram has is different and the situation each and every recipient type faces is different. In addition, the causal link between the 1st stage relative efficiencies and the 2nd relative efficiencies is not considered, which, in turn, is the limitation of this paper.

Fisheries cooperative requires dual characteristics in performing its original function. Economic characteristic as an business enterprise and democratic characteristic as cooperative entity need to complete its objectives and survive in the complex rapidly-changing environment. After IMF crisis, fisheries cooperative received enormous government's financial support and credit-business department is perfectly under government's control. Regional fisheries cooperative also faces business failure, therefore pure cooperative movement can't save the fisheries cooperative. Economic characteristic as an business enterprise is more emphasized than democratic characteristic as cooperative entity in recent years. The theory of corporate ownership and governance can be applied to explain the ownership and governance of fisheries cooperative because fisheries cooperative is now similar to an business enterprise. During the IMF crisis the board, the auditors and the minority shareholders in business enterprise were revealed to be powerless against the mighty influence of controlling shareholders. Unconstrained discretion exercised by those controlling shareholders not only led to the firms'insolvency, but also brought down the country's financial system. During the past few years, Korea has experienced many institutional changes regarding its corporate governance structure. The introduction of outside directors, the strengthening of minority shareholders' rights, and enhanced accounting transparency are achieved to improve the efficiency of economic system. Investors, including institutional and individual, also seem to be more aware of governance issues now. Credit-business department of fisheries cooperative is recommended to introduce the institutions same as the case of the corporate governance structure. Fisheries cooperative except economic and credit-business department requires other prescriptions because it is emphasized as democratic cooperative entity. But we should be careful to interpret the ownership and governance structure because they are products of nations, eras and organizations.

Despite their social mission, social enterprises work in the changing global economic environment and therefore face to comply with performance objectives. This situation means that human resources management strategy has a crucial role to play. Especially, the challenge in maintaining competitive efficiency depends on achieving a lower level of employee turnover. This study aims to investigate the role of job insecurity, job satisfaction, relationship with customers regarding the intention of retention among social enterprise workers. Data were collected in South Korea from 271 women employees in 36 social enterprises and the binomial logistic regression was used to assess the model hypothesized. As the result, social enterprise employees showed a considerably positive attitude toward the intent to stay their workplace. However, job insecurity appeared to have the strongest negative effect on the intention of retention, whereas job satisfaction and relationship with customers had the positive effects, above and beyond demographic variables and organization variables. The result suggested the human resource management can play a significant role in retaining social enterprise employees by reducing job instability and improving job satisfaction and customers management.

Recently, As the IT skills development, the different kinds of data (or information) generated by the company are becoming more frequent leaked to outside organizations and individuals. However, it is insufficient situation to reduce the dysfunctional corporate information at the enterprise level. In this paper, we propose a role-based enterprise information processing model to minimize the dysfunctions of corporate information. The proposed model is to allow you to set protect corporate information through the relevant departments for the management and supervision of enterprise information, and rapid and systematic recovery and operating strategy was to improve the efficiency of enterprise information services. The proposed model is caught blocking access to information access to information to establish a rapid and systematic recovery and operational continuity strategy after the administrator user permissions and roles that access to information is centrally managed by the user when the abnormality. In experimental results, virus damage was lower 48.8% than the previous model. In addition, information on the number of dysfunction distribution occurring within the company gained 17.9% lower results than the previous model.

The modern society has been drastically changed from the industrial economic society to the knowledge based society, to catch up with the knowledge and the change of technology required for the modern people, the people can not live in the modern society without the continued study or education. In case of architectural design firm, it is concentrating on the productivity of enterprise by cultivating the working level through the self education focused on the improvement of inner capacity. In connection with this, the efficiency of enterprises are analyzed by carrying out the Data Envelopment Analysis(DEA) utilizing the financial ratio index in the various field of industries recently, the analysis study for the efficiency utilizing DEA is increased in the construction industries as well. However, in case of construction industries, the study focused on the efficiency of administration only has been progressed, it is the real situation that the approach for the analysis of education efficiency of each enterprise is very insufficient. Therefore, this study analyzed the education efficiency of architectural design firm after the selection of input and output variables by utilizing the DEA model and utilizing the AHP analysis technique by deducting the variables through the preceding study in relation to the education efficiency and the interview with the specialists.

In this paper, we propose a cache algorithm based on user's context for enterprise/urban smallcell environments. The smallcell caching method is to store mobile users' data traffic at a storage which is equipped in smallcell base station and it has an effect of reducing core networks traffic volume. In our algorithm, contrary to existing smallcell cache algorithms, the cache storage is equipped in a edge server by using a concept of the Mobile Edge Computing. In order to reflect user's characteristics, the edge server classifies users into several groups based on user's context. Also the edge server changes the storage size and the cache replacement frequency of each group to improve the cache efficiency. As the result of performance evaluation, the proposed algorithm can improve the cache hit ratio by about 11% and cache efficiency by about 5.5% compared to the existing cache algorithm.

This study analyzed the efficiency and influence factors according to the main research institute type of R&D Program for the local community problem-solving. This study applied data envelopment analysis (DEA) method and Tobit regression analysis by using 20 institutions that participated in R&D Program. The results are summarized as follows. First, Analysis results according to the research institute type of R&D project, Efficient DMUs showed more regional innovation institutions than social economy enterprises. But regional innovation institutions were the lowest in the CCR and BCC model. However, efficiency dose not differ between regional innovation institutions and social economy enterprises. Second, as a result of the analysis relation between efficiency and allocation characteristics of R&D input, the participation of regional innovation organizations as participating organizations has a negative effect on efficiency. It was found that the higher the proportion of government subsidies and the higher the employment rate of the vulnerable, which is a social achievement, the positive effect on efficiency. The implication of this study is that the participation of social economy enterprises as the main R&D institution and government R&D support can provide social economy enterprises with opportunities to accumulate R&D capabilities and experience successful commercialization.
