In this study the comparative analysis of four nations' Delphi technological forecasts in information and communication industry was carried out. The nations were Korea, Japan, Germany and France. The reliability test of realization time forecast was also conducted. There were some technologies of which four nations forecast almost same realization time whereas other technologies which four nations showed large variance in forecasting realization time. This means that experts from different nations had different views and prospects on the same technology. It is expected that prospecting international technological trend from this study will contribute to formulating long-range plan for technological development in information and communication in Korea. The result of the comparative analysis of four nations' forecasts in information and communication technology can be summarized as follows. a)As for the realization time, most of the technologies were forecast by four nations to be similar, the differences ranging from one to three years. It was found that on the whole, the longer the time of the forecast, the bigger the variance. The German forecast showed the biggest variance. b)In reliability test Korean was found to be the most reliable and Japan, France and Germany were in descending order. The response of all panel members was found to be more reliable than that of the panel members with high expertise, which means that there were substantially different views among panel members with high expertise on the realization time of the same technology.

The purpose of this study is to examine the focus realization of [Adjective+Noun] phrases which are used in English classroom situations. In order to examine this, two production and one perception experiments were designed. The noun phrases in the first two production experiments are divided into three patterns according to the location of focus. The difference between the two production experiments is that in the first experiment the focused words are contextually given in the classroom situation, but in the second experiment they are presented in written form. We compare the native English teachers' focus realization of noun phrases with that of Korean teachers from the point of view of intonational phonology. In the perception test, we examine how the uttered sentences are perceived by English native speakers and Korean native speakers. The results from the three experiments show that native English teachers' focus realization is quite consistent with informational structure. Also, there is a significant difference in pitch range of adjectives and nouns when the native speakers give pitch accents on the two content words, and the uttered sentences are mostly perceived as well as the speakers' intentions. As for Korean speakers, however, they usually focus only on the adjective or they focus on both the adjective and the noun, regardless of the relative informativeness of these words. From these findings, we can conclude that focus realization of Korean teachers is rather inconsistent with respect to informational structure when compared to that of native English teachers.

An intralaboratory comparison of the realization of the triple-point temperature of mercury, which is defined as -38.8344℃ on the international temperature scale of 1990 (ITS-90), was conducted at the Korea Research Institute of Standards and Science (KRISS), the national metrology institute of Korea. To this end, four triple-point-of-mercury cells were compared using the resistance ratio measurement of a standard platinum resistance thermometer to validate the calibration results obtained using the triple-point-of-mercury cells at KRISS. The triple-point temperatures of all the four cells, one of which is designated as the national standard cell, were within 0.3 mK of the national standard. Based on 13 experiments on the four triple-point-of-mercury cells, the uncertainty in the comparison of the triple-point-of-mercury cells was 0.08 mK, and the uncertainty in the realization of the triple-point temperature of mercury was 0.19 mK. The results of the intralaboratory comparison validated that utilizing any of the four triple-point-of-mercury cells would result in the realization of a temperature within 0.3 mK of the average value determined by two key international comparisons for the realization of -38.3844℃ following the ITS-90.

Management of the workforce in the early career stage who enter information security work after graduating from college or university so that they can continue to develop their information security careers without leaving the organization can be a solution to the problem of absolute shortage of staffing and lack of skills. This is because the workforce can improve their job skills, and organizations can build a stable, cost-effective human resource management system. This paper constructed and verified a turnover intention research model focusing on the factors that affect the turnover intention of early-stage workforce who took their first steps in society as an information security workforce after graduating from university or college; it confirmed that self-realization is a crucial factor. Furthermore, with in-depth interviews, the career path information of skilled workers, which is essential information necessary for self-realization, was analyzed, and the direction of HRM for self-realization of the workforce in the early career stage was presented.

This paper is on weighted model reduction using structurally balanced truncation. For a given weighted(single or double-sided) transfer function, a state space realization with the linear fractional transformation form is obtained. Then we prove that two block diagonal LMI(linear matrix inequality) solutions always exist, and it is possible to get a reduced order model with guaranteed stability and a priori error bound. Finally, two examples are used to show the validity of proposed weighted reduction method, and the method is compared with other existing methods.

An $H_2$/$H_{\infty}$ -controller realization is carried out by considering an entropy integral. Using J-spectral factorization, the parametrizations of all $H_{\infty}$ stabilizing controllers are derived. By the relation of a mixed $H_2$/$H_{\infty}$ control problem and a minimum entropy/$H_{\infty}$ control problem, the mixed $H_2$/$H_{\infty}$-controller state-space realization is presented.

This paper has been studied driving circuits in electrical valves. Also in this paper, opto-couplers of driving circuit are replaced with digital one chip of Altera company. Designs in order to realization of one chip are carried out with Altera Max Plus II. For compact size and light weight, the realization with one chip is necessary in the electrical valves. This paper has designed and presented the digital schemetic circuits, finally the driving circuits are sucessfully operated with the designed chip and showed the saving of area in the driving circuits of electric valves.

Since 1970s, there are many tries to realize electronic bills of lading(e-B/L) in the world and great attention has been shown to the question of law, international trade customs and realizing strategy concerned that instrument. However that tries, include Bolero which is most famous company serving e-B/L, don't succeed yet. Meanwhile, Korean government amended commercial code in order to realize e-B/L on August 3, 2007. Also The Korea Paperless Trade Center set to develop the e-B/L system by spring of 2008. So far, however, no definitive answer has been given to the way of realization of e-B/L in Korea. Getting bigger the importance of analysis to the ways of realization of e-B/L in Korea, in this paper the author attempt to examine the requirements after briefly outlining and analysing the results and problems of the tries and suggest thereby policy and strategy about the realization classified three categories.
