Recently, the interest in Accreditation of Engineering Education, which aims at facilitating the development of engineering education and producing the high calibre of graduates in engineering schools, is increasing. The accreditation requires the students to prepare a portfolio which shows the educational achievements from all courses at the university. In the portfolio, educational activities and outputs of the student are included as a part of the achievements. Particularly, in the portfolio of design-related courses, outputs of the design the student has made until the graduation are accumulated. The outputs enable others to measure the design capability of the student and can be used as important reference materials when applying for employment or graduate school. In this paper, I propose a format of the portfolio for practical exercise courses, engineering design, and undergraduate design and explain the ways of the utilization of the portfolio.

As a new facet of international security realm in 21C, Information Warfare(IW) has rised new way of warfare and demostrated its efficiency in battelfield. With the rapid development of information technology, indeed, it is difficult to estimate the future of IW. While there are a lot of discussion on the clear concep of IW, it is clear that IW has the factor of psychological warfare, so-called cyber psychological warfare. Considering the security environment of Republic of Korea(ROK), the cyber psychological warfare has the significant importance for national security. While it has to deal with the cyber psychological warfare of North Korea, it also try to cope with the various threaten of international conflicts to protect Korean people and national interest.

The increasing application of electronic equipment has heightened the interest in power quality in recent years because there are economic impacts on utilities, customers, and suppliers of load equipment. The power quality would impose result in severe damage on many industrial customers. As having been supplied many kinds of electronic devices such as computer and communication equipment, automation equipment and various kinds of control devices etc., it comes to be more and more difficult to maintain the clean power quality. According to the restructuring in electricity industry the power quality may be treated as goods as contract terms and regulation elements between power supplier and consumer in the near future. Under the above environment, the power quality should be monitored for all day long with appropriate devices which is possible to measure and record the associated power quality data to prove each responsibility for the impacts when disputes arise due to power quality problems power quality problems are occurred. In this paper the authors propose some functions to be considered and system configuration to monitor the associated power quality elements in developing the web based power quality monitoring system.

This paper deals with the experiment of CW YAG laser for processing. The YAG laser is spotted very small size beam compared with $CO_2$ laser having short wave-length. That is used broadly in material processing because of easy reaction to the materials, and the maintenance is very simple. The power delivery and focussing is done conventional optical components, and splitting beam is used many point stop-welding. In these studies, especial interest is nesessary to perpare for future technology. Our study aims to develop the YAG laser system and to accumulate design and construction technology. In basic experiments, we obtain the maximum output power of 50 W with the single elliptical cylinder.

Purpose: This study critically reviewed nursing research psychotropic drugs that has been published in Korean journals. Another aim of this study was to identify trends in nursing research on psychotropic drugs and make suggestions for further study in Korea. Methods: Data were collected from degree theses and original articles on psychotropic drugs published in Korean journals from 1992 to 2013. Thirty-four articles were analyzed of which at least one nursing author participated in the study. Search keywords were "psychotropic drug" and "mentally ill patient & medication". Results: For the research design, quasi-experimental study was 58.8%, descriptive study was 17.7%, descriptive correlational study was 8.8%, qualitative study was 8.8% and model development research was 5.9%. Variables measured were knowledge of medication & symptom management, knowledge of disease, side effects, drug attitude, medication pattern, diet & activity, quality of life, and self-care. Conclusion: Despite recent increased interest in psychiatric medication, research on psychotropic drugs remains very limited, particularly regarding findings from a nurse's perspective. More research project should be designed to develop programs for the treatment of side effects from a nursing view-point.

Currently, various sensors have been used for advanced driver assistance systems. In order to overcome the limitations of individual sensors, sensor fusion has recently attracted the attention in the field of intelligence vehicles. Thus, vision and radar based sensor fusion has become a popular concept. The typical method of sensor fusion involves vision sensor that recognizes targets based on ROIs (Regions Of Interest) generated by radar sensors. Especially, because AVM (Around View Monitor) cameras due to their wide-angle lenses have limitations of detection performance over near distance and around the edges of the angle of view, for high performance of sensor fusion using AVM cameras and radar sensors the exact ROI extraction of the radar sensor is very important. In order to resolve this problem, we proposed a sensor fusion scheme based on commercial radar modules of the vendor Delphi. First, we configured multiple radar data logging systems together with AVM cameras. We also designed radar post-processing algorithms to extract the exact ROIs. Finally, using the developed hardware and software platforms, we verified the post-data processing algorithm under indoor and outdoor environments.

Image-guided neurosurgery (IGN) is a technique for localizing objects of surgical interest within the brain. In the past, its main use was placement of electrodes; however, the advent of computed tomography has led to a rebirth of IGN. Advances in computing techniques and neuroimaging tools allow improved surgical planning and intraoperative information. IGN influences many neurosurgical fields including neuro-oncology, functional disease, and radiosurgery. As development continues, several problems remain to be solved. This article provides a general overview of IGN with a brief discussion of future directions.
