In recent years, NASA, FAA and the aerospace industry, through MIL-HDBK-17 and the NASA-conceived AGATE(Advanced General Aviation Transport Experiments) program, have worked together to reduce the qualification burden imposed on individual aircraft manufacturers. AGATE is one of the most successful public/private cost-haring partnerships ever conceived, bringing together academia, the FAA, other government agencies and industry to develop affordable new technologies and accompanying industry standards and certification methods. In 2005, NASA established NCAMP(National Center for Advanced Materials Performance) with the purpose of refining and enhancing the AGATE process to a self-sustaining level to serve the entire aerospace industry in partnership with CMH-17, FAA, and SAE. In this paper, I will introduce briefly NCAMP process and explain its organization structure and core NCAMP documents. This paper can provide some help in establishing our certification system for composite materials where the NCAMP process is expected to be the most good model.

Modern society is to have an significant impact on the competitiveness of the country in which the economic value is very high occupancy and ensure a state-of-the-art science and technology. The country's core technology or industry security crimes going seized state-of-the-art technology firms can threat of damage to the country's economic security. In particular, the defense industry serious crime that is directly related to national security. The company's core technology and trade secrets leaked once the industrial countries must prevent security breaches and offenses of strict punishment measures because it is impossible to recover. Also, some advanced countries directly has been operating industrial security crime for the country's economy and national security. In recent years, Nation core technology infringement cases are rapidly increasing in the country. In addition, industrial security crime threat to national security. Therefore, the industry security crimes damage to the national security that infringe on the business secrets of core technologies and businesses. It is necessary to identify that industry security crime associated with the visibility of the broad scope of intellectual property protection.

In this paper, we parallelized a feature point extraction algorithm to reduce panorama image generation time in multi-core environment. While we compose a panorama image with several images, the step to extract feature points of each picture is needed to find overlapped region of pictures. To perform rapidly feature extraction stage which requires much calculation, we developed a parallel algorithm to extract feature points and examined the performance using CBE(Cell Broadband Engine) which is asymmetric multi-core architecture. As a result of the exam, the algorithm we proposed has a property of linear scalability-the performance is increased in proportion the number of processors utilized. In this paper, we will suggest how Image processing operation can make high performance result in multi-core environment.

The development and maintenance of a sound bond are essential requirements of concrete repair and replacement. The bond property of a overlay to its substrate concrete during the lifetime is one of the most important performance requirements which should be quantified. A standard or a verified bond strength measurement method is required at field for screening, selecting materials and quality control for overlay or repair materials, but no test method has been adopted as a standard. In this study, a concrete pull off bond strength measurement method for field application is proposed and evaluated. This study compares the splitting tensile test, slant shear test, nipple pipe direct tensile test, flexural adhesion test, briquette tensile test, jumbo nail pull-out test and core pull-off test with their test procedures. From these comparison and investigation, core pull-off test is selected as a main topic of this study because of it's suitability for in situ testing, simplicities in field application and clearness at interface boundary condition. Thus, the proposed core pull off test is evaluated to be the most appropriate method for field application in a simple manner. The fracture surface and fracture mode could be easily determined by visual observation of failure surface of the field specimen. The core pull off test was found to be sensitive to surface condition and latex contents at latex modified concrete.

This paper describes an implementation of a security SoC (System-on-Chip) prototype that interfaces a microprocessor with a block cipher crypto-core. The Cortex-M0 was used as a microprocessor, and a crypto-core implemented by integrating ARIA and AES into a single hardware was used as an intellectual property (IP). The integrated ARIA-AES crypto-core supports five modes of operation including ECB, CBC, CFB, CTR and OFB, and two master key sizes of 128-bit and 256-bit. The integrated ARIA-AES crypto-core was interfaced to work with the AHB-light bus protocol of Cortex-M0, and the crypto-core IP was expected to operate at clock frequencies up to 50 MHz. The security SoC prototype was verified by BFM simulation, and then hardware-software co-verification was carried out with FPGA implementation.

The purpose of this study was to extract the factors of core competency required for technology teachers and to analyze the educational needs for extracted core competency factors and to search for the application of core competencies in the in-service technology teachers education. This study was conducted by literature review, expert validation, and needs assessment method. The survey was conducted by 92 low-carrier technology teachers who participated in in-service technology teachers education for upgrading to first grade teacher certificate. Data were analyzed the factor analysis, needs assessment, and IPA analysis using SPSS 24. The core competencies with high education needs were selected by the score of the Borich formula and the IPA analysis. As a result of the study, 29 factors of core competencies were chosen as the priority: challenge, planning ability, decision making ability, future orientation, intellectual property utilization ability, communication ability, and creative thinking etc. Based on the conclusions of this study, I would suggest the following. It is to create a new in-service education program reflected on core competencies that have high educational needs of low-carrier technology teachers. In addition, a strategy that reflects core competencies methodically in existing in-service teachers education program is needed. Future research should be followed by research on curriculum design to enhance high needed core competencies of low-carrier technology teachers.

Heavy weight of the camouflage materials was always the main problem. To solve it, the low infrared emissivity fibers with the radar absorbing property (LIFR) were prepared. The low infrared emissivity fibers (LIF) were firstly melt-spun by co-extrusion of polypropylene (PP) and PP/various fillers master-batches using general conjugate spinning. The infrared emissivity of LW with AA and ZnO was decreased respectively compared with that of pure polypropylene fibers. The infrared emissivity of LIF with 15 wt% Al and 2 wt% ZnO in the sheath-part can reach 0.58. To improve LIF radar absorbing property, LIFR was prepared by filling the 50 wt% ferrite and bronze in the core-part of LIF. The radar absorbing efficacy of LIFR was good and the infrared emissivity was low. For the characterization, fiber electron intensity instrument and differential scanning calorimetry (DSC) were used for the analysis of mechanical properties, thermal and crystallization behavior of the spun-fibers. Scanning electron microscopy (SEM) was carried out to observe the particle distribution of the bicomponent fibers.
