Catenary maintains the tension of the catenary using automatic tensioning devices to meet performance require m ents exhibited by the house is generated in accordance with the new external temperature changes. Double spring type autom a tic tensioning device is permanent and does not require the usual maintenance, and a deterioration due to no recognizable ab normalities characteristic of the nature of the internal state has the disadvantage that can not be confirmed. The disassembled for automatic spring-tension capabilities ensure efficient operation and life expectancy of the adjustment device via a check by analyzing the changes in old age determine the remaining lifetime is expected to be available as a basis for maintenance in the future.

Cellular senescence is a state of permanent cell-cycle arrest triggered by different internal and external stimuli. This phenomenon is considered to be both beneficial and detrimental depending on the cell types and biological contexts. During normal embryonic development and after tissue injury, cellular senescence is critical for tissue remodeling. In addition, this process is useful for arresting growth of tumor cells, particularly during early onset of tumorigenesis. However, accumulation of senescent cells decreases tissue regenerative capabilities and induces inflammation, which is responsible for cancer and organismal aging. Therefore cellular senescence has to be tightly regulated, and dysregulation might lead to the aging and human diseases. Among many regulators of cellular senescence, in this review, I will focus on microRNAs, small non-coding RNAs playing critical roles in diverse biological events including cellular senescence.

Since the 21st century, to the worldwide computer, broadcasting, communications and other technologies have be developed. because of the Internet allows real-time information delivery, Information Society that was done quickly. In this study, using information technology, Active measures to enable e-commerce in agriculture is discussed. agricultural e-commerce to the consumer satisfaction surveys were conducted, too. In addition to, as a e-commerce features, informance, convenience, interface presented. After research results, I think information, convenience, interface is important to consumers. Consumers will be spent on activities having a new value. To respond to these consumers, Companies must evaluate the internal capabilities. and outside the assessment continuously. E-commerce will give an effective way to companies. And e-commerce will develop further in the future. Therefore, e-commerce will be done by the long-term plan.

As the predominant mode of vertical urban development in China, mixed-use complexes provide the optimal case for the research of sustainable and vertical urbanism. This paper reviews three typical mixed-use complexes with various vertical space systems in Shanghai via the combination of field observation, questionnaires and software analysis. It then proceeds to determine which vertical space system is most effective for encouraging sustainable vertical urban development from the perspective of spatial efficiency. Finally, it concludes with an evaluation of the relative capabilities of the design features of a mixed-use complex: to create external dimensional-connections, to create multiple internal connections, and to organize overall composite functions.

Internet-based retail business spreads rapidly in Korea. Companies are trying to develop and use various strategic capabilities. The strategies employed by those companies include activities related to the design of shopping sites, market positionsing, facilitation of purchasing process, payment mechanism, and the provision of various consumer services. However, the success of these strategies depends on various environmental factors and internal capability of the companies. Especially, balancing activities performed on-line with those performed off-line is suggested to be essential. In this study, we examined three successful Internet shopping mall companies and compared them to draw useful guidelines for balancing shopping mall strategies - on - line vs. off - line. These three companies were selected because they are all considered sucessful by now, but brought different backgrounds.

A methodology for evaluation of mechanical and thermal effects of localized non-axisymmetric oxidation in zircaloy claddings on LWR fuel reliability is proposed. To this end, the basic capabilities of the FALCON fuel behaviour code are used. Examples of methodology application to adjustment of selected operational limits for modern BWR fuel rods, to capture effects of the excess local oxidation, are presented. Specifically, the limiting rod internal pressure for the onset of cladding lift-off is reduced, depending on initial excess oxidation spot sizes. Also, the power limits for Anticipated Operational Occurrences are adjusted, to preclude fuel melting and cladding failure due to PCMI and PCI-SCC in the affected fuel rods.

This review introduces the current technique of photoacoustic imaging as it is applied in imaging-guided surgery (IGS), which provides the surgeon with image visualization and analysis capabilities during surgery. Numerous imaging techniques have been developed to help surgeons perform complex operations more safely and quickly. Although surgeons typically use these kinds of images to visualize targets hidden by bone and other tissues, it is nonetheless more difficult to perform surgery with static reference images (e.g., computed tomography scans and magnetic resonance images) of internal structures. Photoacoustic imaging could enable real-time visualization of regions of interest during surgery. Several researchers have shown that photoacoustic imaging has potential for the noninvasive diagnosis of various types of tissues, including bone. Previous studies of the surgical application of photoacoustic imaging have focused on cancer surgery, but photoacoustic imaging has also recently attracted interest for spinal surgery, because it could be useful for avoiding pedicle breaches and for choosing an appropriate starting point before drilling or pedicle probe insertion. This review describes the current instruments and clinical applications of photoacoustic imaging. Its primary objective is to provide a comprehensive overview of photoacoustic IGS in spinal surgery.

This paper selected 'Line', the messenger application of Korea's leading software-based IT company 'Naver', and performed a case analysis specially in the early stages of the messenger industry. First, this study analyzed what the mobile messenger industry is and the external environment. Next, an internal analysis was carried out through the strengths and weaknesses through Naver Line's resources and capabilities. With this analysis, this study could evaluate the platform strategy, communication strategy, and the user basic strategy that Naver is carrying out. This study gave us more understanding of the mobile instant messenger (MIM) industry and understand Naver's growth strategy, which will provide great implications for the working staff of IT companies.

Micro, small, and medium-sized enterprises (MSMEs) have been acknowledged to play a key role in promoting innovation and economic development. In Peru, 99.5% of formal firms are MSMEs, thus promoting innovation in these firms could have a significant impact on the Peruvian economy. In spite of Innovate Peru's efforts, Peru is still one of the countries that invests the least in innovation, with MSMEs offering low value added. Innovate Peru has launched programs (technological missions) to improve MSMEs' innovation through technology-transfer-oriented subsidies, which may strengthen companies' absorptive capacity (AC) and thus their capabilities to identify and integrate internal and external knowledge. This study assesses the impact of these programs on MSMEs. Data were collected from 85 MSMEs that participated in Innovate Peru's technological missions between 2014 and 2016. Findings show that all the dimensions of AC have a positive impact on innovation; however, the impact of economic subsidy was found to be non-significant. Theoretical and practical implications are discussed.
