  • Antioxidants partially ameliorated the detrimental effects of reactive oxygen species (ROS) on sperm characteristics during in vitro storage. The objective of the present study was to investigate the single or synergetic antioxidative effect of curcumin and Vit. E on the characteristics of fresh boar sperm during in vitro storage. The sperm viability in curcumin, Vit. E supplementation and curcumin+Vit. $E+H_2O_2$ groups remained over 85.0% in 3 hr incubation period, but in 6 hr incubation period, curcumin+Vit. $E+H_2O_2$ groups was sharply dropped than those of curcumin and Vit. E group. The membrane intergrity in all evaluated groups except for $H_2O_2$ group did not significantly difference in 3 hr incubation period. The viability in curcumin or Vit. E supplementation were significantly increased than in curcumin+$H_2O_2$ and Vit. $E+H_2O_2$ group in 6 hr incubation period. The percentage of mitochondrial activity and acrosome intergrity obtained similar trends within same incubation periods irrespective of treatment. The lipid peroxidation of spermatozoal plasma membrane ranged from $11.6{\sim}17.5\;nM/l{\times}10^6$ and $14.0{\sim}19.0\;nM/l{\times}10^6$ in 3 hr and 6 hr incubation periods. In conclusion, curcumin or Vit. E surpplementation alone or cooperatively improved sperm viability index (motility, membrane intergrity, viability and survival rates) and fertility index (mitochondria activity, acrosome intergrity and lipid peroxidation) of fresh boar sperm, indicating that curcumin and Vit. E have a antioxidative properties through its scavenging activity against hydrogen peroxide.

  • Oral health depends on the intergrity of the oral mucosa for prevention of the penetration of microbes and macromolecules that might be infectious, allergenic or antigenic. The intraoral immune systems include the tonsils, adenoids and nasopharyngeal-associated lymphoreticular tissue, or NALT. Mucosal inductive sites of the gastrointestinal tract(Peyer's patches and the appendix) and solitary lymph nodes collectively compose the gut-associated lymphoreticualr tissue, or GALT system. Both NALT and GALT are inductive regions where foreign antigens derived from viruses, bacteria, yeast and other molecules are encountered. The integration of tissues in NALT and GALT as part of the mucosal immune system, is very important to keep the oral immune system.

  • Recently, global pollution reached the critical level. Thus, new paradigm for the development and conservation of natural resources appear. This is so called Environmentally sound and Sustainable development. Ecological Architecture proposed as a proposal for the paradigm. This research deals with Christian Thoughts about the Ecological Architecture planning. The results are as follows; First, Sustainable development is new paradigm that is suitable for the Christian Integrity of Creation. Second, Ecological Architecture will be better when the people have full of the Christian love.

  • The object of this work is to develop an assessment system for pipeline integrity. The system consists of four module applications for internal algorithm; the effect of corrosion in pipeline, crack, stress corrosion crack (SCC) and fatigue modules and the effect of cavity. Presently, the module of the external corrosion has been developed and the internal algorithm for the effect of corrosion in pipeline and the database of the system are described in this paper. The database of the system is separated to mainly four parts; geometry of pipeline, material properties, boundary conditions and general properties. Each components of the system are designed by user-friendly concept. This system may give a guideline for maintenance and modifications for the pipeline at the industrial sight. Furthermore, a procedure to evaluate an inspection interval is also provided.

  • By using personal health devices, a type of bio-censor at home and building, for telemedicine, this paper proposes a new method to protect more robust patient's privacy than before scheme [1] by ensuring the integrity and the secure transmission further when it communicates with gateway which collecting bio-information from them. As the suggested method is designed to conform with ISO/IEEE 11073-20601 [2], which is international standard, it considered interoperability with various health devices.

  • Calcium phosphate ceramics have been applied intensively to orthopaedic and dental implants by virtue of their osteoconductive nature. In an attempt to enhance the bone implant intergrity and Eta utility, these ceramics are deposited onto the porous surface of metallic implants. The coating procedure and the ensuing phase transformations of the ceramic alter the mechanical properties and surface chemistry of the ceramic layers as well as those of the substrate. These structural and compositional differences are directly related to the interaction mechanisms at the surface-active ceramicbone interface. Material and processing induced influences on dissolution, electrokinetic behavior, ceramic-metallic substrate interface and boRe growth enhancement are presented.

  • The porvision against earthquakes and aseismic design of nuclear power plants (NPPs) in Korea are composed of four stages: site-selection, design, construction, and operation stages, Since regulatory criteria are strictly applied in each stage, the NPPs in Korea are believed to have a sufficient safety against maximum potential earthquakes. However, it has been recognized that those regulatory criteria borrowed from U.S. should be replace by Korea-specific ones by using earthquake data obtained from earthquake observation at and around NPP sites. Also, the government made a plan after the Yongwol and th Kyongju earthquakes that the regulatory body operates an independent earthquake network in order to reinforce the earthquake preparedness of NPPs. In compliance with the government's plan, this project is aiming at deployment of an earthquake motoring network composed of four seismic stations at NPP sites to record earthquake ground motions at NPP sites, to derive attenuation formulas of various ground motions and site-specific response spectra, and to develop structural intergrity assesment program.

  • A practically useful system for elastic-plastic fracture mechanics analysis has been developed. The developed system is comprised of the deformation plasticity failure assessment diagram(DPFAD) approach and the J-integral/Tearing modulus(J/T) approach. The system contains analysis routines for five types of fracture specimens : compact tension, center cracked tension, single edge craked plate in uniform tension, single edge cracked plate in three point bending and double edge cracked plate in tension. A double interpolation scheme was adopted to interpolate J values from the EPRI developed EPFM handbook and the Newton-Raphson method was used to obtain proper loadings for displacement control conditions. A graphic output system was utilized to present numerical results. Several case studies were performed to evaluate the accuracy and the usefulness of the code. It was found that the J/T approach and the DPFAD approach yielded similar results. However, the DPFAD approach is more convenient for qick assessment of integrity of cracked structures while the J/T approach is more useful in evaluating the full history of the fracture process.

  • In this study was carried out on the proper number of cadets and the improvement of educational environment that can ensure effective practice on board a training ship. In doing this research, basic data had been obtained from some of the written interviews done with some apprentices and instructors on education, and survey findings on the dimensions of the training facilities and areas available to apprentice in the current training ships. The concepts of ergonomics have been adapted to this study also, in order to increase its reliability. On the basis of what has been discussed just above, we have suggested a navigation integrity consol for deck apprentices and a training room for the operation and maintenance of shipboard machinery for engine apprentices, together with providing a suitable number of cadets that can be accommodated for practice altogether in a given situation.
