  • 국내 EMI/EMC연구는 이제 태동기에 접어들고 있다고 생각된다. 이 연구는 크게 측정과 대책에 관한 연구로 구분될 수 있을 것이나, 두 분야가 상호보완적으로 접근되어야만 보다 효과적으로 연구를 수행할 수 있으리라 여겨진다. EMI/EMC 측정기술과 측정표준에 관련된 분야만 하더라도, 매우 넓은 범위의 다양한 대상이 있기 때문에 제한된 지면으로는 시각과 다른 각도에서 보는 경우도 많이 있으리라 생각된다. 아무튼 EMI/EMC 측정기술의 이해에 조금이나마 도움이되었으면 하는 바램이다. 끝으로 국내 EMI/EMC 측정기술의 향상과 국내적인 측정 신뢰도를 확보하기 위해서 미국립표준기술원(NIST)에서 시행하고 있는 프로그램을 소개하고자 한다.

  • 아직까지 정보보호 활동은 기업의 입장에서 비용을 단순히 소비' 하는 업무로 인식되는 경우가 많다. 때문에 최근의 경기침체가 보안예산의 축소나 보안활동의 위축으로 이어질 것이라는 우려가 적지 않다. 그러나 정작 기업 정보보호 담당자들의 시각은 다른 것으로 나타났다. 오히려 경기침체가 정보보호 강화의 계기가 될 것이라고 전망하는 담당자도 적지 않았다. 정보보호 부서와 역할 범위가 강화되는 것으로 해석해 볼 수 있는 대목이다. 기업 보안 부서와 담당자들의 역할 변화를 감지할 수 있는 기업 정보보호 실태조사 결과의 일부를 소개해 보고자 한다. 이번 설문조사는 지난 3월 24일 (사)한국침해사고대응팀협의회가 개최했던 CONCERT FORECAST 2009 참석자 중 110명을 대상으로 실시한 것이다.

  • In this thesis, the ambulatory aid mechanism was implemented so that blind people could be safer at risk of walking outdoors. Using ultrasonic sensors, the obstacles can be detected when the distance between the obstacle is within 50 cm of the obstacle. If the light sensor becomes less than 25 lux, the LED will automatically turn on and help the safety of the visually impaired and the security of sight of the peripheral walkers. Color recognition sensors increase the rate of recognition of yellow color by the detection distance is 1cm, it vibrated when yellow light was detected. Using GPS with 7.3 m of error range, the guardian was able to check the location of the visually impaired.

  • In spite of the usefulness of migration statistics in spatially understanding social processes and identifying social effects of spatial processes, services and analyses of the statistics have been restricted due to the complexity of their data structure. In addition, flow mapping functionality which is a useful method to explore and visualize the migration statistics has yet to be fully represented in modern GIS applications. Given this, the purpose of this research is to demonstrate the possibility of flow mapping and the exploratory spatial analysis of the migration statistics in a Web GIS environment. For this, the characteristics of the statistics were examined from database, GIS, and cartographic perspectives. Then, O-D structure of the migration statistics was converted to spatial data appropriate to f low mapping based on the characteristics. The interface of Web GIS is specialized the migration statistics and provides exploratory visualization by allowing dynamic interactions such as spatial focusing and attribute filtering.

  • The automated visual inspection system (machine vision system) for quality assurance is important factory automation equipment in the manufacturing industries, such as display, semiconductor, etc. There is a lot of demand for the machine vision engineers. However, there are no technical training courses for machine vision technologies in vocational schools, colleges and universities. In this paper, we present the implementation of line scan camera based equipment for technical training of the automated visual inspection system. The training system consists of the X-Y stage which is widely used in machine vision industries and its variable image resolution are set to $10-30{\mu}m$. Additionally, this training system can attach the industrial illumination, either the direct illuminator or coaxial illuminator, for verifying the effect of illuminations. This means that the trainee can have a practical training in various equipment conditions and the training system is similar to the automated visual inspection system in industries.

  • This study improves the design of electric pot and cup that can safely pour and drink hot beverages among daily necessities for the blind and the elderly. It looks at the electric pot and cup that people with visual impairments usually use through their use perspective and studies and improves the safety problems that arise when using them based on the principle of universal design. Through this prior study, we study designs that can be used and shared by all disabled and socially disadvantaged people together and improve the design of household goods to expand the scope of use of general products and create new social values. In addition, through this design improvement process, everyone pursues an equal and virtuous life together, forms a well-off inclusive society, and takes advantage of the current position of the disabled and value of life once again.

  • Schedule management is one of pivotal project success factors during construction projects. However, there are many difficulties in rapid scheduling and controlling since the existing planning techniques require considerable amount of manual work and manager's judgment in a construction project. This research aims to propose a new scheduling method and algorithm for automating and visualizing the planning process, which is called Countable-grid scheduling method. In this method, if the scope of work is defined via a visualized tool, the schedule plan is created automatically according to the productivity and workable conditions of each activity. The location of the work for each date can be visualized in grid-based approach. Moreover, the work schedule can be updated automatically according to the progress. The industrial applicability of the proposed method was verified in construction projects via case study with sample data. This research can contribute to the construction industry by automating the construction schedule management process.

  • Unlike a study related in language alone, rhetorical study of current time, composed with multi-culture, medias, communication, presents its own field that covers from the form of discourse(persuasive) to another form of discourse(not persuasive). If there was a study of making beautiful sentences for story and finding simple method of speech in Greek and roman period of an ancient time, it now a study in which one finds the essence of literary style or terminology in the expression of sentence. The taller case is especially important, given that the importance of what to express visually is on-going active procedure of this stuffy as itself an activity of communication. When a visual object persuades viewers, the activity of communication derives them to react and to understand the intention of an artist. The matter of how to speak is the matter of how to shape message persuasively. This persuasive method or technique is study of rhetoric. The three aspects (figurative, accentuating, mutating) of rhetorical expression of an illustration, the visual image can give fresh feelings to be in intimate relations with public. These rhetorical expressions also vitalize the story that is expressed on illustration with crisp image. It helps to attain expected effects while discovering essential meaning through the corresponding linguistic interpretation of an image. The study aims at the most effective way to communicate by figuring the most strong and direct illustrative message out. One of the method is to patternize illustrative expressions that are established from all kinds of shapes of Rhetoric. Therefore ,an operation of significance and an implication can shape an ultimate goal of this study from acknowledging the mechanism that modern illustration embraces.
