  • This paper presents the design of a submerged breakwater, which functions as an eco-structure in a marine environment. Newly patented blocks were used in the submerged breakwater to both make it stable and provide an inhabitable space for fish. To investigate the wave transmission of the proposed submerged breakwater, parametric studies were conducted through two-dimensional hydraulic tests, which were carried out at the National Fisheries Research and Development Institute (NFRDI) in South Korea. Those parameters are relative crest width (B/L), wave steepness (H/L), relative crest depth (hB/H), and submerged breakwater configuration. The hydraulic experimental results can be used to predict the performance of the proposed submerged breakwater covered with the multi-function blocks.

  • Recently, as the design of a system gets larger and more complex, functional verification method based on system-level becomes more important. The verification of a functional block mainly uses BFM(bus functional model). The larger the burden on functional verification is, the more the importance of configuring a proper verification environment increases rapidly. SystemVerilog unifies hardware design languages and verification languages in the form of extensions to the Veri log HDL. The processing of design description, function simulation and verification using same language has many advantages in system development. In this paper, we design DUT that is composed of AMBA bus and function blocks using SystemVerilog and verify the function of DUT in verification environment using layered testbench. Adaptive FIR filter and Booth's multiplier are chosen as function blocks. We confirm that verification environment can be reused through a minor adaptation of interface to verify functions of other DUT.

  • The purpose of this study is to investigate the effect of functional ability on relocation among the elderly. Longitudinal data from the Asset and Health Dynamics among the Oldest Old (1993, 1995) were analyzed for 6,225 respondents aged 70 or older. Among functional ability measures, difficulties in advanced activities of daily living (i. e., making telephone calls, taking medications, and managing money), lower body activities (i. e., walking several blocks, climbing one flight of stairs, pulling or pushing large objects, and carrying over 10 pounds), and household activities of daily living (i. e., preparing hot meals and shopping for groceries) were the predictors of increased residential move. Difficulties in basic activities of daily living (i. e., bathing, dressing, getting in and out, and using the toilet) were strongly related to increased entrance into an institutional care facility. Efforts to enhance the independent living of the elderly in the community setting should target the compensation of these functional difficulties.

  • This paper presents a graphics accelerator for fast image generation. The accelarator has three major functional blocks: linear interpolator, multipliers and Edgee Painting Tree. Linear interpolator with coupled binary tree structure interpolates functional values of two end points. Two multipliers compute input values of interpolator in parallel. Mask pattern which removes out invalid data is generated by Edge Painting Tree. The proposed architecture in this paper is responsible for 64 pixels and can process about 5,900 10x10polygons per second.

  • This is a report on a case of delayed reconstruction after partial mandibularectomy for Ameloblastoma involving symphysis and bodies of the mandible by using of two large pieces of corticocancellous bone blocks obtained from both iliac crests. The authors failed immediate reconstruction with two kinds of Alloplasts(metal, methylmethacrylate) at two times of trial due to known infection and suggestive poor histocompatibility of materials aginst the host who has been suffered from long-term and active pulmonary tuberculosis. However we could get success late reconstruction of this problem-occured and curved area with two pieces of large corticocancellous blocks by using of miniplate osteosynthesis and biphasic external pin fixation. From our experience we are obtained some results as follows : 1. Alloplastic graft materials seemed to be dangerous to maintain successfuly in patient who has a long-term debilitating disease as a active pulmonary tuberculosis. 2. Biphasic external skeletal pin fixation appliance gave many advantages such as maintain functional position of the remained bodies and condyles of the mandible after removal of failed alloplasts and during control of inflammation of this area, assist supportive roles to fix and maintain bone grafts during healing, allow mandibular movement during healing and so offer to conduct normal functional stimuli to bone grafts during osteogenesis etc. 3. Bony union was successful between not only normal bones and grafted bones but also grafted bone pieces even though we used two pieces of large blocks of corticocancellous bone for graft. 4. Miniplate osteosynthesis was not affect any adverse effects to bone grafts but offered good role of fixation and maintenance for bone grafts.

  • Modular toys for creative education require functional blocks to create various types of movements. An active drive module and a lot of passive connection blocks are needed to express motion with combination. In this paper, we propose the design of modular toys to produce various creative movements and controller structure working with them. In order to facilitate the connection between the designed modules, a connection method and a suitable mechanism are suggested. We also dealt with the design of various types of sensor modules that can work in conjunction with modular toys. Using these toys, typical standard application form that can be imitated educationally is suggested and showed the usefulness of the modular toy by actually applying it with designed modules and components. The proposed method is applied to actual educational toys, and the operation is effectively performed by recording operation and playing repetitive operation.

  • The Functional Element SNPs Database (FESD) categorizes functional elements in human genic regions and provides a set of single nucleotide polymorphisms (SNPs) located within each area. Users may select a set of SNPs in specific functional elements with haplotype information and obtain flanking sequences for genotyping. Our previous version of FESD has been improved in several ways. We regenerated all the data in FESD II from recently updated source data such as HapMap, UCSC GoldenPath, dbSNP, OMIM, and $TRANSFAC^{(R)}$. Users can obtain information about tagSNPs and simulate LD blocks for each gene from four ethnicities in the HapMap project on the fly. FESD II employs a Java/JSP web interface for better platform portability and higher speed than PHP in the previous version. As a result, FESD II provides its users with more powerful information about functional element SNPs of human ethnicities.

  • Nanostructured materials can be engineered by the controlled assembly of several suitable nano-objects as the building blocks. While, materials properties are determined by their atomic and molecular constituents and structure, their functionalities emerge when the microstructure of these early ensembles is in the nanometer regime. The properties and functionalities of these ensembles may be different as their size grows from the nano-regime to the micron regime and bulk structures. Nanotechnology, offers a unique possibility to manipulate the properties through the fabrication of materials using the nano-objects as building blocks. Nanotechnology is therefore considered an enabling technology by which existing materials, virtually all man-made materials, can acquire novel properties and functionalities making them suitable for numerous novel applications varying from structural and functional to advanced biomedical in-vivo and in-vitro applications.

  • The European Telecommunication Standards Institute (ETSI) Technical Committee (TC) Reconfigurable Radio Systems (RRS) is standardizing the multi-mode Mobile Device (MD). The configuration of multi-mode MD is determined by the downloaded mobile communication standard software. In this paper, we introduce the Radio Library concept for multi-mode MD which is one of the key components of RRS standard. This paper also introduces the Standard Functional Block which is a part of Radio Library. A method for selecting efficiency SFBs for multi-mode MD is presented and a Radio Library is generated based on the selected SFBs. This paper also shows sample Standard Functional Block Set which included in Radio Library. In order to verify the compatibility of the generated Radio Library which was made by C language, we implement the LTE Rel-10 and Wi-Fi(802.11b) to show the efficiency of generating a mobile communication standard software based on the Radio Library. Then using the Prograph Visual Programming MartenTM 1.6.4, we compiled our LTE Rel-10 and Wi-Fi(802.11b) source code.
