The underlying purpose of this paper is to interest scholars in 'Trade English'. 'Trade English' has to be recognized as one area of 'International Trade' disciplines and more studies have to be carried out with more attention from the scholars. Although there are many areas to be dealt with in 'Trade English', this paper discusses about the syllabus design of 'Trade English' from an educator's point of view. First of all, this paper reviews some theoretical background researches about needs analysis and syllabus design in 'Trade English' teaching and learning as ESP. With a systematic structure under the decent syllabus, selection and sequence of contents get clear and easier. Secondly, along with the rationals based on theoretical researches, how these theories are being or can be applied to the real classroom are discussed for further studies. A different syllabus would be designed according to needs analysis. In reality, the syllabus for practitioners who are doing their jobs in International Trade areas has to be definitely different from the one for pre-practitioners who are studying in International Trade areas at the tertiary education level. Namely, different learners present different needs and different needs make up the different syllabus. In order to provide these learners with the syllabus which can address their own needs, more researches or studies have to be done in the future. Since 'Trade English' is the discipline where two areas-International Trade and English as a second/foreign language-are mixed, the researches or studies also have to be carried out collaboratively by scholars from both areas.

The purpose of this study is to analyze the trends after surveying Korean researches on writing classes of science and engineering college students. In this study, we reviewed the trends of the researches and summarized the fields of the journals. The contents of researches were classified into the general discussion on the science and engineering writing class and the discussion on the contents of education and the teaching methods. The flow of discussion about writing class was developed in detail closely related with characteristics of science and engineering discipline, composition of writing class, educational goal and curriculum of engineering education certification system. A number of researches have proposed contents and methods of education developed through the analysis of textbooks, school and case studies. It is necessary to develop active research on various perspectives and topics such as students, teachers, evaluation, and systems in the future.

There are many researches on the organization formation and business strategy of architecture firms to improve of organizational capability. However the previous researches have been only focused on the improvement of organizational capability and efficiency in management parts of view. There have been lack of the researches on evaluation of organizational capability. Especially, there are no researches on the evaluation of organizational capability reflecting the characteristics of architecture firms which is mainly operated by human resources. Therefore, the objective of this research is to develope a index frame for evaluating organizational capability of architecture firms in Korea. The proposed indexes can be used in evaluation of organizational capability and analysis on correlation between organizational capability and performance of organization in architecture firms.

The bibliometric analysis is widely used for understanding research domains, trends, and knowledge structures in a particular field. The analysis has majorly been used in the field of information science, and it is currently applied to other academic fields. This paper describes the analysis of academic literatures for classifying research domains and for suggesting empty research areas in the telecommunications policy. The application software is developed for retrieving Thomson Reuters' Web of Knowledge (WoK) data via web services. It also used for conducting text mining analysis from contents and citations of publications. We used three text mining techniques: the Keyword Extraction Algorithm (KEA) analysis, the co-occurrence analysis, and the citation analysis. Also, R software is used for visualizing the term frequencies and the co-occurrence network among publications. We found that policies related to social communication services, the distribution of telecommunications infrastructures, and more practical and data-driven analysis researches are conducted in a recent decade. The citation analysis results presented that the publications are generally received citations, but most of them did not receive high citations in the telecommunications policy. However, although recent publications did not receive high citations, the productivity of papers in terms of citations was increased in recent ten years compared to the researches before 2004. Also, the distribution methods of infrastructures, and the inequity and gap appeared as topics in important references. We proposed the necessity of new research domains since the analysis results implies that the decrease of political approaches for technical problems is an issue in past researches. Also, insufficient researches on policies for new technologies exist in the field of telecommunications. This research is significant in regard to the first bibliometric analysis with abstracts and citation data in telecommunications as well as the development of software which has functions of web services and text mining techniques. Further research will be conducted with Big Data techniques and more text mining techniques.

A lot of researches about dye-sensitized solar cell (DSC) are recently being conducted. Because DSC has several advantages to pass the limits of silicon solar cells such as a low manufacturing expense, a simple manufacturing process and its transparency. But most researches on DSC are still conducted about the unit cell and laboratory-centered. That is, present researches on DSC are not practical. Therefore, researches about large area cells and modules have to be prerequisites for DSC to have the practicality. Characteristics of large area DSC are so different from those of small area DSC in aspect of fill factor and efficiency. In this study, we made an experiment on finding suitable size of DSC that has the most effective power according to the variation of active area. In detail, the experiment was conducted about the optimum ratio of length to width and we introduced the ratio of active area to non-active area to find the active area which has the best output. Because small DSC doesn‘t have the best output in comparison with total area of cell although the smaller DSC has the better efficiency. As a result, we achieved the optimum ratio of length to width of 8:3 and active area of $8cm^2$ as the optimum size for upscaling DSC.

Recently, many researches in relation to data transmission with faster speed and greater volume, many researches have been carried out on sonar systems for underwater communication. According to these researches, an acoustic transducer for underwater communication requires wide bandwidth properties. In domestic researches for underwater communication sonar, an operating frequency in the range of $20{\sim}40\;kHz$ is used. In this paper, we propose anon-resonance type acoustic transducer for underwater communication. The TVR (transmitting voltage response) characteristics increased linearly as the frequency increased, and the RVS (receiving voltage sensitivity) characteristics were constant as the frequency increased. Traditional techniques for wide bandwidth transducershave a limit and a transmission loss difference at lower and higher frequency operating ranges. In this paper, the new transducer proposed decreased the transmission loss under some conditions. It was optimized with the FE analysis tool (ATILA) and evaluated using the TVR and the RVS characteristics in the range of $10{\sim}90\;kHz$. The value of TVR was 138 dB at 20 kHz and 148 dB at 40 kHz, and the differences was 12 dB. The value of RVS was $195{\pm}2\;dB$ and nearly constant. From theseresults, it is certain that the developed transducers can be used for an underwater communication network in the 1.3 km range with both a 20 kHz bandwidth and 30 kHz center frequency.
