  • Nanofiber is a broad phrase generally referring to a fiber with diameter less than 1 micron. Various polymers have been successfully electrospun into nanofibers in recent years. These nanofibers, due to their high surface area and porosity, have a great potential for use as filter medium, adsorption layers in protective clothing, etc. Nanofiber filters will enable new levels of filtration performance in the field of air filtration. In particular, nanofibers provide marked increases in filtration efficiency at relatively small pressure drop in permeability. Therefore, nanofiber filters could be substituted for conventional filter market due to the easy application of process and the possibility of coating to micron-sized non-woven sheets. This review is discussed on the trend of researche and development related to nanofiber filter including future marketability.

  • The swine waste industry is growing rapidly along with the world human population. The trend is toward more concentrated piggeries with numbers of herds in the thousands. Associated with these increased herds are large quantities of wastes, including organic matter, inorganic nutrients, and gaseous emissions. The trend in swine waste management is toward treatment of these wastes to minimize negative impact on the health and comfort of workers and animals and the atmosphere, water, and soil environments. Treatment of these wastes has traditionally involved land application, lagoons, oxidation ditches, and conventional batch and continuously stirred reactor designs. More sophisticated treatment systems are being implemented, involving advanced anaerobic digester designs, integrated with solids separation, aerobic polishing of digester effluents, and biological nutrient removal. This review discusses the present and future role of anaerobic processes in piggery waste treatment with emphasis on reactor design, operating and performance parameters, and effluent processing.

  • The age of specialization is upon physical therapy, as evidenced by the many special interest group. One of the special interest is manual therapy, which is the study of neurology, biomechanic, behavior science and pathology as well as the application of evaluative and treatment techniques of the neuromusculoskeletal system. Trend of manual therapy cover the whole medical in Europe. but America has two categories which is the neurologic manual therapy and the orthopedic manual therapy. The neurologic manual therapy was integrated with theory of PNF, Bobath technique, Vojta which is neurophysiologic approach concept. It is called motor control. A key aspect of the motor control requires a through knowledge of neurobiologic, biomechanic, and behavioral science. The orthopedic manual therapy runs to the evaluation and treatment of joints and their surrounding structures increase or decrease mobility and Fain control. In this article has to define and clarify the basic concepts of orthopedic manual therapy by comparing the general concepts, evaluation schemes, and treatment procedures of John McM Mennell, James Cyriax, Geoffrey Maitland, Freddy Kaltenborn and Ola Grimsby.

  • Currently in the Web(World Wide Web) environment, HTML(Hyper Text Markup Language) is used for information representation and exchange. But it is thought that HTML has some constraints in information representation of various kinds because of its limited tag set. And it is considered that combining the HTML, which is used for static information representation in Web environment, with Scripting language, which is usually used for multimedia information representation in a synchronized framework, can be very useful. Consequently we show the general trend of the Scripting language in Web environment and show the possibility of HTML and Scripting language amalgamation for Web service improvement.

  • The number of studies on social media has increased rapidly worldwide. There has been, however, little effort to assess the achievements and limitations of social media studies up to present. The purpose of this study is to provide a systematical viewpoint on social media research published by scholarly business-related journals. Our analysis focus on research topic, functionality, targeted media types, methodology, and characteristics. User research receives the most attention, followed by effect research in terms of developmental models of media research agenda. The major methodological trend is online survey. Facebook and twitter are the two most popular mediums studied in literature, and social media is mainly characterized as information sharing as well as relationship building. Two recommendations are suggested in ways to strengthen social media research: more various topics and application areas, and the rigor and diversity of research methods.
