In the last ten years, the area west coast of Sumatra island has several times experienced the earthquake with strong intensity. Starting from the earthquake in Aceh December 26, 2004 until 30 September 2009 earthquake Pariaman ago. The last earthquake measuring 7.9 on the Richter scale has killed more than 1,000 people and damaged buildings 279 432, with 50 percent of them were severely damaged. Another alternative that is better than doing demolition is to retrofit. In general, the retrofit can be described as the addition of new technology or new technology on a merger between the old system (which already exists). In other words, the retrofit is the process of retrofitting old buildings with the aim of making these buildings resistant to earthquakes. From the calculation and analysis conducted on the carbon material, the material Sika Wrap Hex 230C can be used to retrofit House Office Building Customs Bayur Gulf of Padang. The method of implementation should be properly cared for, so that the strength of the building is expected back as they are resistant to earthquakes. It should be noted once in choosing the method of retrofitting that we will use.

A gas quenching process to deal with steel slag and its characteristics of the new technology was briefly introduced. The grinding characteristics, mineral phases of gas quenching steel slag and the potential economic benefits of using it as cement mixing material was studied by compared to heat-stew steel slag. The results indicated that the specific surface areas (S) and grinding times (t) of the gas quenching steel slag showed a first order exponential decay relationship. With the extension of time, the specific surface areas of heat-stew steel slag was tending to balance earlier than that of gas quenching steel slag; The energy consumption of gas quenching steel slag was much lower than that of heat-stew steel slag. Gas quenching steel slag was comprised of C2S, C3S, a certain amount of (Ca2(Al, Fe)2O5）and RO phase, but the content of RO phase was relatively low, which increased the grindability of the quenching steel slag, so that the grindability of gas quenching steel slag was much better than that of heat-stew steel slag. Gas quenching steel slag prepared for cement addictives would bring great economic benefits.

In the paper the new technology of solospun and its principle of spinning are introduced. The yarn produced in this method is better than the normal yarn with the same count. This kind of yarn has the high strength and the characteristics of high resistant to abrasion and less hairiness etc. It can improve the efficiency of single strand to weave as well as provide the advantageous conditions for developing high count, light and thin product. Technology of solospun has wide prospect for development and application.

The cleanliness of the casting blanks could seriously affect the quality of downstream products. Recently, ultrasound technology has been introduced to detect the inclusions in metal materials. However, due to the anisotropy of the material crystal, the ultrasonic wave has the characteristics of multiple scattering and refraction in its propagation process. This makes it difficult to evaluate the casting blanks cleanliness effectively, for the inclusion echoes are submerged in the background noise. Therefore, the ultrasonic microscope is innovatively proposed to carry out efficient scanning on the casting blanks. In the meantime, the morphological filtering algorithm has the advantages of fewer parameters and faster calculation speed which can be used to increase the signal-to-noise ratio of ultrasound images and extract the defect features more efficiently. In order to verify the effectiveness of the proposed method, specimens were taken from three strands of continuous caster for detection and analysis. The experimental results show that the second strand has the best quality and the cleanliness is 2.2/mm3, which is obviously better than the other two strands. This method will provide a new technology for the quantitative evaluation of the internal quality of the casting blanks.

Telemedicine (TM) involves the use of technology to overcome the patient care barriers of distance and time. Asynchronous TM can be used to monitor patients remotely and for providers and patients to communicate with each other without needing to be online at the same time. Synchronous TM can include direct-to-consumer visits in which patients use their own equipment to communicate with a provider or facilitated visits in which a patient travels to a clinic to use the clinic’s equipment with a facilitator. The advantage of the latter is that a physical examination can be performed. Although some patients and providers may prefer in-person visits, patients who are seen by TM report satisfaction that it is as good as or better than that of an in-person visit. TM can be used in the outpatient setting, in the hospital to perform consults, or in the school. The convenience of TM makes it likely that more patients will adopt TM as their preferred mode of obtaining health care. It is important for allergists to become familiar with this new technology because patients will demand it.

This paper extends the work of Wang (2002) by considering a differentiated Stackelberg model, when the leader firm is an inside innovator and licenses its new technology by three options, that is, fixed-fee licensing, royalty licensing, and two-part tariff licensing. The main contributions and conclusions of this paper are threefold. First of all, this paper derives a very different result from Wang (2002). We show that, with a nondrastic innovation, royalty licensing is always better than fixed-fee licensing for the innovator; with a drastic innovation, royalty licensing is superior to fixed-fee licensing for small values of substitution coefficientd; however whendbecomes closer to 1, neither fee nor royalty licensing will occur. Secondly, this paper shows that the innovator is always better off in case of two-part tariff licensing than fixed-fee licensing no matter what the innovation size is. Thirdly, the innovator always prefers to license its nondrastic innovation by means of a two-part tariff instead of licensing by means of a royalty; however, with a drastic innovation, the optimal licensing strategy can be either a two-part tariff or a royalty, depending upon the differentiation of the goods.

Dimensional stability of carding machine has a greater impact on the performance of the Cylinder wallboard. Compared with the thermal stress relief (TSR), the vibratory stress relief (VSR) is a new technology which may eliminate the residual stress in metal components with high efficiency, energy saving, environmental protection and low cost. We have 8 pieces of cylinder wallboard castings with every 4 pieces as a group. It takes 20 minutes to do VSR in one of the groups and 20 hours for TSR in another group. Three identical size accuracy indexes are measured, respectively at intervals of 1 month 2 months after aging treatment. The results show that: the dimensional stability of cylinder wallboard vibration by VSR is better than the one by TSR. Energy consumption and cost-saving is more than 90% without "three wastes" emissions.
