There has been a new trend to integrate various kinds of circuits by low temperature polycrystalline silicon thin film transistor (LTPS TFT) on insulator substrates to achieve System on Panel (SOP) for flat panel displays. In this paper, we will review the trend of the SOP and discuss the utility and future possibility of the SOP.

In a resent paper, Na and Kim(2000) develop a family of test statistics for testing whether or not the mean residual life changes its trend based on complete data and show that the new tests perform better than previously known tests. In this paper, we extend their tests to the randomly censored data. The asymptotic normality of the test statistics is established. Monte Carlo simulations are conducted to compare our tests with a previously known test by the power of tests.

There are several methods for the hydrogen production such as steam reforming of natural gas, photochemical method, biological method, electrolysis and thermochemical method, etc. Many researches have been widely performed for the hydrogen production method having low production cost and high efficiency. In this paper, the patents concerning the photochemical hydrogen production method were gathered and analyzed. The search range was limited in the open patents of USA(US), European Union(EP), Japan(JP), and Korea(KR) from 1996 to 2005. Patents were gathered by using key-words searching and filtered by filtering criteria. The patent application trend was analyzed by the years, countries, companies, and technologies.

Appearance, which is directly related to competitiveness, has become one of the essential self-care for modern people living in the era of the 4th industrial revolution. For the purpose of producing more practical and convenient wigs for suffering customers, data of research subjects were collected through an information search portal site. The trend of new material development of leading wig companies was analyzed. As a result of the study, it was found that many applications for wig attachment and binding technology were applied before 2005, artificial hair-related manufacturing technology for wigs from 2006 to 2013, and functional-related wig technology after 2014. In addition, both H and M companies showed the development trend of new materials for shape memory materials and nanoskins with their own characteristics. We believe that this study will be provided as basic data for the development of functional wigs that can lead to customer satisfaction while providing customers with a comfortable and convenient fit in the wig industry market.

The applications of white LEDs has been expanded from mobile phone to LCD TV as a backlight source recently and now are penetrating into the lighting market. With these changes new requirements for LEDs phosphors are demanded. In this point of view recent technology trend of phosphors for LCD backlight and lighting will be discussed.

It is no more make consumers feel the freshness about a simple and functioned style reminding to the cyber-future style made by shining materials. Rather than that stereo-type of the future, people at present tend to feel more interested in something familiar than something new. Even though the amazing product made by human for better life, people become feel afraid that value be getting disappear, and it is natural that people should put more value to the nature, admire it, people try to find the new beauty in something worn being able to be felt the passed time. The vintage has turned up in the fashion area out of the mode of the antipathy from standardization, overconsumption, and also demand of a special thing different from mass product. The vintage is not the past-inclined trend but the new trend that people try to seek in the future to feel both comfort and newness. This study analyzed the vintage fashion style getting more important and also how the vintage fashion shows focusing in the domestic fashion market. The results as follow.: There are two meaning in vintage fashion, one of two is the recycled fashion style that current fashion made with used clothing, or reforming with new and old, Second, there is the new style using the past image, so called as the revival fashion. The totally current trend can be made in something new mixed with material or silhouette from past thing. The vintage fashion as recycled and reformed fashion will be more demanded from consumers who want to be comfort and still try to pursuit something new.

Although the generic implementation of aqueous two-phase systems (ATPS) processes for the recovery of biological products has been exploited for several years, this has not resulted in a wide adoption of the technique. The main reasons involve the poor understanding of the mechanism governing phase formation and the behavior of solute partitioning in ATPS processes, the cost of phase forming polymers, and the necessary extended time to optimize the technique. In this review paper, some of the practical disadvantages attributed to ATPS are addressed. The practical approach exploited to design ATPS processes, the application to achieve process integration, the extended use for the recovery of high-value products, and the recent development of new low-cost ATPS, are discussed. It is proposed that the trend of the practical application of ATPS processes for the recovery of biological products will involve the purification of new high-value bioparticulate products with medical applications. Such a trend will give new impetus to the technique, and will draw attention from industries needing to develop new, and improve existing, commercial processes.
