Technological forecasting for microprocessor market can provide timely insight into the prospects for significant technological changes in computer hardware as well as software. In this paper, we use bibliometrics to forecast R&D trend on microprocessor technology. Cumulative numbers of US Patents on several generations of microprocessor technology (pipeline, superpipeline, supersclar and VLIW) approved since 1980 are applied to fit diffusion models. Our study results provide both the maximum market potential and the maturity time for each generation of microprocessor technology. Such information is expected to make contribution on making better decisions with regard to strategic corporate planning, R&D management, product development and investment in new technology of microprocessor.

Videophone service was developed and marketed by AT&T in the late 1960s and early 1970s. The market did not respond to the service offering, and the service was withdrawn. However, Videophone returned in the late 1980s and early 1990s. Due to the technological advance, establishment of ITU standards and fall of videophone price, many analysts are very optimistic about videophone market. But on the other hand, some analysts anticipate that recent videophone will only replicate the past with the same results: namely, market failure. First, this article reviews the history of videophone service, the recent development trend and reasons for its market failure. Second, this article reviews prospects for videophone service. Finally authors examine some of the technological and service features that might shift the value of videophone service.

There are technological changes to reduce the size and weight of electronic components and to accommodate multi-functions in them. To meet this trend, more complicated technological processes are required. To maintain the processes, more accurate inspection systems are also necessary. Therefore, new inspection methods are needed, which is differ from conventional inspection methods such as electrical test methods ICT(In-Circuit Test), FCT(Function Test) and visual test using optical equipments. One of the possible approaches is non-destructive test using X-ray. In this paper, an inspection method using X-ray is developed and applied to inspection of soldering state and internal defects of electronic components.

Our present ability to work with video has not been confined to wired communication environment. This paper describes the new technological trend of wireless video communication. In wireless video communication, unlike wired network, several techniques are needed. At first, error robust video coding is essential. Due to characteristics of wireless channel, the system is exposed to more error prone environment. In addition, encoded video bit streams are vulnerable to the error because of the entropy coding. Recently many frameworks are developed to cope with this problem. We just explore the numerous robust video coding approaches with the viewing of error control. And more we discuss other on going research topics in this wireless video communication fields like low-power assumption design, trans-codec technique, and rate control schemes in brief.

Dynamic changes in the field of labor relations have become a general trend in the world practice. These changes are due the impact of globalization and technological innovation above all. Concept of "precarization of employment" appeared due the new emerging labor relations. This term has been used for more than thirty-five years, but there is still no generally accepted definition of it. A wide range of authors' viewpoints on problem of precarization makes it vague and impossible to strictly to identify its borders. Features of its manifestations in different countries also complicate the problem. Kazakhstan is a country with export-oriented economy of raw materials. At the same time government try to solve the problem for the industrial-innovative development of the economy. These two factors bring additional specific features in the manifestation of the precarization of employment in the country. The aim of the paper is to identify the features of "precarization of employment" concept in Kazakhstan's practice, based on the proposed definition.

NEOs are comets and asteroids that have been nudged by the gravitational attraction of nearby planets into orbits that allow them to enter the Earth's neighborhood. When the NEOs with certain size impact in the Earth's surface, it could cause a serious disaster. However, the NEOs that are potentially the most hazardous because they can closely approach the Earth are also the objects that could bemost easily exploited for their raw materials. This paper presents the characteristics of NEOs and the technology trend of advanced countries on spacecraft missions to comets and asteroids.

Optical frequency comb generators have been investigated as a signal source capable of generating highly stabilized ultrafast pulse lasers. The precise control of the optical frequency comb spacing by RF clock signals has led to a revolutionary paradigm shift in the precise measurement of time and frequency. Optical frequency combs also have advantages such as stable frequency spacing, stable number of lines, and robustness. Owing to these characteristics, optical frequency combs have been applied to the fields of high precision optical clock, communication, spectroscopy, waveform generation, and astronomy. In this article, we introduce the properties (i.e., generation methods, advantages, and so on) of various optical frequency combs, and discuss the expected future technological trends and applications.

With the world in financial recession, the general trend of global trade is declining. As a result, the world leading shipbuilding industries are confronted with an even more difficult task of mitigating various risks associated with the industries. How well the three shipbuilding industries, Japan, Korea and China, can adapt and manage the risks will be crucial. As the youngest of the top three, the Chinese industry faces greater risks. As it happens to share many factors with that of South Korea in 2004-2005, it is necessary to review and evaluate the risk management plan used by South Korea. This paper presents an evaluation of the risk management plan for shipbuilding industry in South Korea during 2004-2005, considering the financial and political environments at that time. This will help us to structure a plan of risk management for the future.

In this research, policies, and technology trends associated with quantum computers were examined, and through this, implications for domestic methods were derived. It is not a guarantee that developing quantum computing technology suited for domestic use would be successful to emulate the success stories of technology-leading nations. Technology leaders like the United States, China, and Europe are putting together strategic technology blocks to compete for technological hegemony. Adapting to and exploiting this trend will help us develop future technologies and secure market competitiveness. The dominant technology in the area of quantum computing has not yet been established. In the future, there will be fair competition in every specific technology area. At this point, it may be claimed that making audacious decisions will still lead to technological superiority.

As recognized by all scientific and industrial groups, carbon dioxide($CO_2$) capture and storage(CCS) could play an important role in reducing greenhouse gas emissions. Especially carbon capture technology by dry sorbent is considered as a most energy-efficient method among the existing CCS technologies. Patent analysis has been considered to be a necessary step for identifying technological trend and planning technology strategies. This paper is aimed at identifying evolving technology trend and key indicators of dry sorbent from the objective information of patents. And technology map of key patents is also presented. In this study the patents applied in korea, japan, china, canada, US, EU from 1993 to 2013 are analyzed. The result of patent analysis could be used for R&D and policy making of domestic CCS industry.
