의견의 주체를 찾는 일은 의견 분석의 결과를 활용 하는데 있어 필수적인 분야이다. 본 논문은 발안자를 찾는 시스템의 성능을 높이기 위해 이전논문에 제안하였던 단어에 의견주체의 후보로서의 점수를 부여하는 방법을 개선하였고 미등록어 문제를 해결하기 위해 taxonomy에 의존하여 기존단어의 점수를 이용하는 방법을 제안하였다. 본 논문에서 제안한 방법은 Baseline과 비교하여 F1값이 18.9% 증가하였다.

Deep learning models, which imitate the function of human brain, have drawn attention from many engineering fields (mechanical, agricultural, and computer engineering etc). The major advantages of deep learning in engineering fields can be summarized by objects detection, classification, and time-series prediction. As well, it has been applied into environmental science and engineering fields. Here, we compiled our previous attempts to apply deep learning models in water-environment field and presented the future opportunities.

Nowadays, the existing manual method for recording actual progress of the construction site has some drawbacks, such as great reliance on the experience of professional engineers, work-intensive, time consuming and error prone. A method integrating computer vision and BIM(Building Information Modeling) is presented for indoor automatic progress monitoring. The developed method can accurately calculate the engineering quantity of target component in the time-lapse images. Firstly, sample images of on-site target are collected for training the classifier. After the construction images are identified by edge detection and classifier, a voting algorithm based on mathematical geometry and vector operation will divide the target contour. Then, according to the camera calibration principle, the image pixel coordinates are conversed into the real world Coordinate and the real coordinates would be corrected with the help of the geometric information in BIM model. Finally, the actual engineering quantity is calculated.

In order to investigate of technology competitiveness for domestic engineering enterprise, using the quantitative and objective patent. In these result, the technology competitiveness(Patent Activity Index, Patent Family Size Index, Patent Impact Index, Technology strength) of our enterprise is far inferior to another country. So we should try to achieve our superiority in competitive power, we devote ourself to put through technical improvements of our domestic engineering enterprise in many ways.

Recently, the interdisciplinary linkage between engineering and social science has received an increasing attention as an emerging education discipline. Due to intrinsic complexity of innovation process and heterogeneity of disciplinary nature, however there exists little, if not no, effort to draw a common framework in terms of educational scope and contents of the new subject. This paper presents a number of criteria and guidelines for building up new educational framework by integrating engineering subject and social science subject. Specifically, three neo-disciplines, technology policy, technology management, and economics of technology are considered since it is postulated that the forementioned disciplines have established academic identity and fundamental structure By nature, this paper is an exploratory and seminal one. It is not the purpose of this paper to provide a concrete table of contents of educational material. Instead, it merely brings up a discussion topic for the wide audience of academic arena, leaving the gradual consensus and convergence as future task.

Current Western-dominated paradigms of technology are based on a reductionstic view, i.e., machines evolve to an intelligent but isolated object form by serially integrating precise subtechnology, humans and the environment through K rperlichkeit(corporeality or philosophy of Mom), is explored. Parallelism based on holism and embodiment, and relative interactions based on correspondence and interrelationships, are the key ideas in the proposed paradigm. An interactive system, called the Emotional intelligence Interface and Performance System(EIPS), is proposed and implemented to explore the proposed interactive technology paradigm. Also, recent collaborations by ASTA(Arts, Sciences & Technology in Asia), an interdisciplinary project team of artists and engineers, are introduced to demonstrate these explorations.

This paper examines the academic basis, current status, and future directions of liberal education for engineers as consilience education. After paying attention to the lists of liberal education for engineers including history of technology, technology and society, engineering ethics, economics of technology, management of technology, and technology policy, I found the academic basis of liberal education for engineers in science and technology studies or innovation studies. And then I monitored how liberal education for engineers is managed focusing on the case of Pusan National University and introduced new attempts on liberal education for engineers in other universities in Korea. Lastly, the future directions for the development of liberal education for engineers were suggested such as the strengthening of lecturers' expertise, the reconstruction of engineering education course, and the promotion of relevant academic associations' cooperation.

In this paper, a new definition of short-circuit ratio concept for multi-converter HVDC systems is proposed. Analysis results of voltage interaction between converters show that the reactive power-voltage characteristic of a converter has a dominant effect on voltage interaction level compared with its active power-voltage characteristic. Such a relation between converter reactive power and voltage interaction level supports taking the former into account in the definition of short-circuit ratio concept for multi-converter systems. The proposed definition is verified by the method of maximum power curve for various system configurations. Furthermore, a formula to calculate transient overvoltage for multi-converter systems is derived based on the proposed definition, and the efficiency of the derived formula is verified.

We show that the electrical properties of organic thinfilm transistors(OTFTs) can be enhanced by controlling the morphology of interface between screen printed electrodes and gate dielectrics. Modified surface of the insulator layer($SiO_2$) affect on the interface energy of electrode on $SiO_2$ layer. Contact angle measurement and FT-IR spectrum shows that the interface is properly modified. OTFTs device with high efficiency has been realized through modification of interface layer.
