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.

The purpose of this study was to identify types of perceptions regarding the activation of physical activities for individuals living in disability residential facilities using Q methodology and to derive implications based on these findings. To achieve this, an open-ended survey was first conducted with prior research, field experts, and specialists in adapted physical education to create a total of 25 Q statements. Subsequently, a Q sorting was conducted with 22 facility staff members, and the results were analyzed using the PQ Method 2.3.5 program. The analysis revealed three types: government support, expansion of disability sports facilities, and consensus building. It was confirmed that expanding physical facilities that actively support participation in physical activities through government support and improving societal perceptions of disability sports activities are crucial for enhancing physical activities in disability residential facilities. These research results provide a basis for policy documents and direction setting for future activation of physical activities in disability welfare facilities.

Purpose : To investigate the difference of total activation in visual area, motor area, and cerebellum according to the stimulation paradigm. Materials and Methods : Functional MR imaging was performed in 5 healthy volunteers with visual and motor activity using EPI technique. LED and Checker-Board stimulation were performed for visual activity. Thumb motion and Finger Tapping were performed for motor and cerebellum activity. Stimulus timing was 60sec. off, 120sec. on, 60sec. off. Data processing was carried out by using the cross-correlation method for each pixel. Each pixel was then selected and assumed activated if the correlation coefficient was equal or larger than a threshold value. Time course data was obtained by calculating the total activation which was defined as the number of activated pixel x averaged pixel intensity. Results : In the case of visual activity with LED stimulation, we found increased total activity of more than 100% compared with Checker-Board stimulation. In the case of motor area and cerebellum with Finger tapping stimulation, we found increased total activity of more than 10% and 150%, respectively compared with Thumb motion stimulation.

The purpose of this study is to analyze the survey and prove the role and impact of teacher librarian's professionalism on the School Libraries Revitalization. The samples of the survey, consisted 96 school libraries in Kyungbuk Province, were revitalized before 2005 by School Library Revitalization Project of Ministry of Education and Human Resources, Korea. The samples were divided into two groups; the one group consisted of 47 libraries managed by teacher librarian, and the other group consisted of 49 libraries which were managed by class teachers who are not majored in Library Science. The questionnaires were mainly conducted by survey but interview, telephone, and e-mail method also used. The state of the art of the library management, including budget, acquisition, cataloging, collection management, circulation, information technology, and the services for the faculties and students between two groups were analyzed and compared. The results showed that teacher librarian group offers more user-tailored and intensive services than class teacher group.

The purpose of this paper is to examine the activation of harbor city renovation projects through analyzing the measures of residents participation and urban marketing, based on case study of Busan North Harbor Redevelopment Project. The main results of this study are as follows. Firstly, according to questionnaire survey, public opinion surveys, citizen advisory committees are more effective as the methods collecting residents' opinion. Especially, residents' opinion is most important on the stage of deciding final alternative. Secondly, according to questionnaire survey about urban marketing, respondents prefer local government as a main agent of urban marketing. They prefer improving urban infrastructures as a main issue of urban marketing. They also prefer enhancing positive image of havor city and promoting the city for foreign tourists, as effective measures of urban marketing. As a result, activation of harbor city renovation projects will be activated through the residents participation and urban marketing, because those may stimulate creative and distinctive development ideas.

Purpose : To evaluate the effect of global scaling analysis on brain activation for sensory and motor functional MR imaging study. Materials and methods : Four normal subjects without abnormal neurological history were included. Arm extension-flexion movement was used for motor function and 1KHz pure tone stimulation was used for auditory function. Functional magnetic resonance imaging was performed at 3T MRI (GE, Milwaukee, USA) using BOLD-EPI technique and SPM2 was employed for data analysis. On data analysis, the brain activation images were obtained with and without global scaling by fixing other parameters such as motion correction and realignment. Results : The difference in brain activation between no scaling and global scaling was not large in case of right upper extremity movement (p<0.000001). For auditory test, brain activation with global scaling showed larger activation than that of without global scaling (p<0.05). Conclusion : A caution must be taken into account when analyzing functional imaging data with global scaling especially for functional study of small local BOLD signal change.

The purpose of this study is to examine the importance and satisfaction of users in the use and selection of a dance academy and contribute to methods for the activation of a dance academy based on basic information. A questionnaire survey was conducted with 213 users attending 12 dance academies in G Metropolitan City using the IPA statistical method. The following conclusions were drawn. The highest importance of a dance academy in IPA analysis was a professional teacher, followed by clean dance equipment, transit accessibility, dance academy fee, and a kind teacher. The highest satisfaction was a professional teacher, followed by various dance programs, teacher's choreography ability, a kind teacher, and transit accessibility. Based on the findings, dance academy users felt that the professionalism and kindness of teachers who directly teach them, academy fee, and equipment cleanliness associated with the age of COVID-19 were important. High satisfaction factors were teacher-related factors and transit accessibility. Therefore, it is considered that a professional and kind teacher and clean and hygienic environment will contribute to the activation of a dance academy.

In this study, the effects of Low Earth Orbit(LEO) environments on the degradation behavior of epoxy nano silica composite materials were investigated. The nanocomposite materials containing silica particles in different weight ratios of 10% and 18% were prepared and degraded in a LEO simulator to compare with the neat epoxy cases. Thermogravimetric analysis (TGA) was performed on the degraded nanocomposites and the activation energies were calculated by Friedman method, Flynn-Wall-Ozawa (FWO) method, Kissinger method, and DAEM (Distributed Activation Energy Method) based on the iso-conversional method. As the results, for the neat epoxy sample cases, it was found that the average activation energy was increased as the degradation was progressed. When the nano particles were mixed, however, the energy increased to the 15 environmental test cycles, and decreased afterwards, meaning that the particle mixture contributed adversely to the thermal degradation. Discussions on the results of the different calculation methods were also given.
