Efficient production of antigen specific cytotoxic T cells is critical for appropriate adoptive immune response. In vitro culture and expansion of human T lymphocyte clones are very sophisticated and subtle procedure in immune cell therapy and hard to control. Therefore, many groups devoted their efforts to manipulate artificial antigen presenting cells (aAPCs) that can induce T cell activation and clonal expansion. To mimicking of natural antigen-presenting cells, aAPCs encompass basic signal molecules required for T cell activation: MHC:antigen complexes, co-stimulatory molecules and soluble immune modulating molecules. Orchestrated organization of these molecules is important for efficient T cell activation. Here, we discuss how those molecules have been incorporated in several aAPC models, but also how physical properties od aAPC are important for interaction with T cells.

Opening agricultural market expansion, reduced purchases through wholesale markets, expanding the influence large retailers of consumer's market such as changes in the distribution system to the farmer's market conditions are changing rapidly. Because of this, retailers of the scaled and chain-store operations was centered on distribution environmental changes of the consumer market place. In producing area due to changes in market conditions in the agricultural production of in producing area distribution organization and the size distribution can not be put off no longer challenge is imminent. If it do not raise forces banded together, the producer is bound to remain as the weak. To support the distribution of this production was introduced in 2000 enable the Activation Project of in producing area distribution. Recent in producing area Changes of Agricultural conditions in order to cope with the Small-scale farmers and small individual farmers are becoming Scaled and specialized. Also, is specific to each item and regional is showing aspects. Government support for Activation Project of in producing area distribution is greatly improved, but in terms of competitiveness on the market still is showing the limitations. The most common of these problems, the market response if in producing area producer's organization and scale of the problem. Equipped for the purpose of consumer market place responsiveness unreasonable propelled outward from the Painter-sized weakens the organizational power. also, Difficult to succeed organizational size is a dissolution or anything within a few years, farmers around the best producer organizations, such as deviation occurs is exposed to a variety of issues. In this study, previous studies refer to the recent changes in agricultural retail environment, background and needs of organization·scaled, Determine the status of the domestic in producing area organizations and derived Problems, look into Domestic and overseas of in producing area organization with best practices for enhancing the competitiveness of the proposed improvement are intended to. In the future, in producing area distribution policy would like to provide direction to the development. The results of the study showed the follwing : 1) enhance utilization and orrganized through the diversification of the agricultural Collection systems. 2) Scaled to achieve through Items of specialized a wide area marketing. 3) Management operating units, such as installation and operating that overseas the best practices " Comite Economique Agricole Regional 'Fruits et Legumes' de Bretagne". 4) To establish a support system that in producing area distribution organization model development for appropriate domestic. In particular, in case of domestic in producing area distribution organization, through the analysis of various case study that a successful organization and scaled. The process of the various challenges arising in organizational scaled and generalization, and by the way he goes about trying to overcome is required.

Networking together hundreds or thousands of cheap sensor nodes allows users to accurately monitor a remote environment by intelligently combining the data from the individual nodes. As sensor nodes are typically battery operated, it is important to efficiently use the limited energy of the nodes to extend the lifetime of the wireless sensor network (WSN). One of the fundamental issues in WSNs is the coverage problem. In this paper, the border coverage problem in WSNs is rigorously analyzed. Most existing results related to the coverage problem in wireless sensor networks focused on planar networks; however, three dimensional (3D) modeling of the sensor network would reflect more accurately real-life situations. Unlike previous works in this area, we provide distributed algorithms that allow the selection and activation of an optimal border cover for both 2D and 3D regions of interest. We also provide self-healing algorithms as an optimization to our border coverage algorithms which allow the sensor network to adaptively reconfigure and repair itself in order to improve its own performance. Border coverage is crucial for optimizing sensor placement for intrusion detection and a number of other practical applications.

Korean sixth industrialization policy is similar to that of Japanese such as goal of policy, setup and promotion method of specific policy projects as it benchmarked a Japanese case. First of all, the certification systems of both countries, the most representative policy, are very alike that the governments officially certificate management bodies, prepare the ground for continuous sixth industrialization, devide intermediate support organization into the central unit and regional unit, and have the function of support and control of sixth industrialization management bodies. Furthermore, both countries create fund for sixth industrialization as an investment support policy, and push forward with the phased support policy businesses such as individual support and connected support for management bodies. However, there are some differences between certification systems of both countries such as process-oriented or result-oriented for certification, subtle differences of the role in support organization, and the range and rate of support.

It is important to explore ways that reinforce teachers' curricular expertise at the school level as the school curriculum autonomy expands. This study investigated teachers' curricular expertise that is required for teachers' professionalism, autonomy, and accountability to cope with the increasing school curriculum autonomy. Teachers in the future school are expected to explore and develop school level curriculum within a given school context. Through literature reviews, domestic and foreign case studies, and survey of teachers, this study examined difficulties in science teachers' exercise of their professionalism on curriculum organization and implementation at the school level. Difficulties in exercising teachers' curricular expertise include lack of actual autonomy in curriculum operation at the school level, inadequate infrastructures, demanding accountability based on students' achievement results, lack of time for reflection, and lack of recognition for teachers as independent curriculum designers. In the conclusion section, a couple of ways to solve these difficulties are suggested including expansion of actual autonomy, activation of teachers' participation in policy decision making, reinforcement of qualitative components in school assessment, diversification of the teacher's career ladder, and activation of teachers' participation in professional learning communities.
