Multi-view super-resolution (MVSR) refers to the process of reconstructing a high-resolution (HR) image from a set of low-resolution (LR) images captured from different viewpoints typically by different cameras. These multi-view images are usually obtained by a camera array. In our previous work [1], we super-resolved multi-view LR images via image fusion (IF) and blind deblurring (BD). In this paper, we present a new MVSR method that jointly realizes IF and BD based on an integrated energy function optimization. First, we reformulate the MVSR problem into a multi-channel blind deblurring (MCBD) problem which is easier to be solved than the former. Then the depth map of the desired HR image is calculated. Finally, we solve the MCBD problem, in which the optimization problems with respect to the desired HR image and with respect to the unknown blur are efficiently addressed by the alternating direction method of multipliers (ADMM). Experiments on the Multi-view Image Database of the University of Tsukuba and images captured by our own camera array system demonstrate the effectiveness of the proposed method.

The successful knowledge and information based companies facilitate to restructure the industry and strengthen the national competitiveness in the future. The advent of information age provides us new challenge because the information breakthrough can play a pivotal role in terms of knowledge transfer in the human resource management. Executive officer must present long term vision in order to expand enterprise continuously and establish long term management goal and strategy which are appropriate for key organizational skills of future management environment (Pfeffer, 1998). Also, long term talent management based on vision, goal and strategy and talent development strategy and employment management must be established (小池, 1994)). American HRM system's reformation cannot be defined without scientific management policy. However, currently widely discussed Japanese HRM system's reformation cannot be defined without organizational commitment focused Japanese employment system. (津田, 1992 ; 太田, 1994). Japan's development of the following policies are behind comparing to Europe : (1)Skill based talent management regardless of age, sex, nationality, race and academic background (2)Consideration of retirement age of 64 (3)Creativity and freedom promoting talent management policy. Also, there are problems to be solved. Solutions will be searched for by establishing new wage policy based on tasks and individuals in the basis of lifetime employment system.

Strategic agility plays an important role in maintaining a competitive advantage for companies, where information systems are introduced. The purpose of this study is to analyze the impact of the introduction of the information system on the strategic agility of the company through the analysis of the "H" resort, which has recently built the information system. Research shows that the introduction of resort management information systems promotes the level of strategic sensitivity, collective commitments and resource liquidity, which are key elements of strategic agility. This study confirmed that the establishment of resort information system has a positive effect on practitioners who want to create strategic agility. However, this study is a single case study and it is difficult to argue that the introduction of information systems is a positive for the strategic agility approach.

This study looked into these companies and organizations that were working with the knowledge management system in order to verify how practically such introduction of the knowledge management system would affect the organizational performances. The purpose of this study is to present the strategic guidelines should to consider the introduction of the knowledge management system operated by the organization to analyze how factors affect the performance of the introduction of knowledge management systems are organized in empirical. According to the results, the sub-variables of the management factors such as learning organization, evaluation and reward system, organizational trust and knowledge-sharing activity had all the significant effects on the organizational performance, and of the sub-variables of the information technology factors, the information technology-based structure presented statistically significant results which confirmed that the structure itself also had an influence on the organizational performance. However, the study learned that both the information technology maturity and the system structural excellence had nothing to do with the organizational performance.

In hospitals and pharmacies, the distribution of medicines is an important part. Any mistakes, misses, fake medicines and expired medicines can cause medical accidents. With the widespread application of the Internet of Things technology (IoT), traditional drug distribution methods need to be upgraded. This article proposes a drug distribution management scheme based on the Internet of Things technology. In the production of drugs, a flexible RFID tag was printed on the packaging box, which stored a series of information such as drug name, dosage, raw materials, efficacy, production date, expiration date, and manufacturer. The use of a drug distribution management system combined with RFID readers can identify drug information and effectively prevent the occurrence of erroneous, missed, counterfeit, and expired drugs. It can also improve management efficiency, reduce management costs, and control management risks. Through the circuit design and software system development, the test results show that this solution is effective and feasible, the proposed method can achieve the expected results.
