정재은,Jung, Jason J. 한국정보통신학회 2011 한국정보통신학회논문지 Vol.15 No.2

본 연구는 이러닝을 실시하는데 있어 플래시와 같은 애니메이션 콘텐츠가 미치는 영향에 대하여 알아보았다. 보다 구체적으로 애니메이션 콘텐츠의 어떠한 속성들이 개인정보보안 관련 이러닝 학습에 긍정적인 영향을 미치는지 알아보고자 하였다. 그 결과 플래시 애니메이션의 속성인 캐릭터와 스토리가 학습자들의 이러닝 학습 효과를 높이는데 긍정적인 영향을 미치는 것을 알 수 있었다. As information and communication technologies (ICTs) has been developed, it is getting more important for internet users to consider many security issues (e.g., privacy protection). In this paper we claims that animation contents make a positive influence on teaching such computer securities, and investigate what features of animation contents will be the most important relationships with performance of the teaching process. Once we have obtained the survey results from students, two main features (i.e., characters and plots) of the animation contents have positively influenced the performance of e-learning systems.

이 연구는 플라이애쉬와 고로슬래그를 치환한 방청 폴리머 보수모르타르의 개발을 위한 기초실험이다. 주요변수는 폴리머 수지 치환율, GGBS와 FA 치환율 및 방청제 치환율이다. 주요 측정항목은 초기슬럼프, 재령별 압축강도, 재령 28일 휨 강도, 건조수축 변형률이다. 실험 결과 모르타르의 압축강도 발현을 고려하였을 때 FA와 GGBS의 적정 치환율은 각각 10%와 20%로 추천될 수 있었다. 또한 방청체 치환은 모르타르의 압축강도를 감소시키는데, 적정 방청제 치환율은 1.5% 이하가 고려될 수 있었다. 한편 모르타르의 휨 강도는 ACI 318-11에서 제시하는 값인 $0.63{\sqrt{f_{ck}}}$보다 컸으며, 건조수축 변형률도 재령 10일 이후에는 ACI 209 예측값보다 낮았다. The present study prepared 13 mixes to examine fundamental mixture proportions of corrosion inhibitor repair mortars. The mortar mixes were classified into three groups according to the selected test variables which are the substitution level of polymer for Group 1, ground granulated blast-furnace slag (GGBS) and fly ash (FA) for Group 2, and corrosion inhibitor for Group 3. Based on the test results, the optimum substitution levels of GGBS and FA could be recommended as 10% and 20%, respectively, though 1-day strength of mortar significantly decreased with their substitution. Furthermore, the appropriate substitution level of corrosion inhibitor was considered to be less than 1.5%. The flexural strength of mortar tested was higher than the predictions obtained from ACI 318-11 equation. The shrinkage strain of mortar was also conservative after an age of around 10 days compared with the predictions of ACI 209.

I think this will be valuable reference for assuring consistency and homogeneity of clarity and managing dental radiation equipment by experimentation of dental radiation equipment permanent which based on KS C IEC 61223-3-4 standard and KS C IEC 61223-2-7. Put a dental radiation generator and experiment equipment as source and film(sensor) length within 30 em, place the step-wedge above the film(sensor). Tie up tube voltage 60 kVp, tube current 7 mA and then get an each image through CCD sensor and film by changing the exposure time as 0.12sec, 0.25sec, 0.4sec. Repeat the test 5times as a same method. Measure the concentration of each stage of film image, which gained by experiment, using photometer. And the image that gained by CCD sensor, analyze the pixel value's change by using image J, which is analyzing image program provided by NIH(National Institutes of Health). In case of film, while 0.12sec and 0.25sec show regular rising pattern of density gap as exposure time's increase, 0.4sec shows low rather than 0.12sec and 0.25sec. In case of CCD sensor density test, the result shows opposite pattern of film. This makes me think that pixels of CCD's sensor can have 0~255 value but it becomes saturation if the value is over 255. The way that getting clear reception during decreasing human's exposed radiation is one of maintaining an equipment as a best condition. So we should keeping a dental radiation equipment's condition steadily through cyclic permanent test after factor examination. Even digital equipment doesn't maintain a permanent, it can maintain a clarity by post processing of image so that hard to set it as standard of permanent test. Therefore it would be more increase the accuracy that compare a film as standard image. Thus I consider it will be an important measurement to care for dental radiation equipment and warrant homogeneity, consistency of dental image's clarity through comparing pattern which is the result from factor test against cyclic permanent test.

정재은 ( Jae Eun Jung ),이주원 ( Choo Won Lee ),한연희 ( Yeon Hee Han ) 한국패션비즈니스학회 2011 패션 비즈니스 Vol.15 No.1

In order to develop a new fashion business curriculum, this study attempts to evaluate fashion business curriculum in both domestic and foreign schools and to analyze their existing training programs. The results of this study shows that the analysis of domestic fashion business curriculum shows that ``in the field`` knowledge is in need for the new fashion education program where students can be more exposed to the industry environments especially in the area of markets, sales, distribution and management. Also, the analysis of fashion marketing curriculum of F.I.T and PARSONS school of design demonstrates their emphasis on practical as well as academic programs in marketing, distribution and merchandising. In addition, the research on sales person training program reflects that future sales persons will need stronger knowledge in customer analysis, product display and shop management. Based on these findings, this investigation proposes a revised second year fashion business undergraduate program. The academic program in this updated module will place heavier emphasis on such fields as marketing, distribution, product planning and sales management. Also recommended is that the second year students will be exposed to real-world experience by participating in various internships and workshops offered by major companies in the fashion field.

웹 환경 하에서의 제약 만족 기법에 의한 공간 계획 시스템

정재은(Jae-Eun Jung),전승범(Seung-Bum Jeon),조근식(Geun-Sik Jo) 한국정보과학회 2000 정보과학회 컴퓨팅의 실제 논문지 Vol.6 No.2

공간 계획 시스템(Spatial Layout Planning System)은 사용자의 요구에 따라 사각의 자원을 일정 공간 안에 할당하고 사용자의 만족도를 최대화함으로써 공간 효율성을 최적화하는 시스템이다. 공간계획 문제는 방대한 범위의 공간을 탐색해야 하므로 시간과 공간적 측면에서 높은 복잡도(Complexity)를 갖는 문제이다. 또한 특정 영역의 수정 요구나 재설계 요구와 같은 사용자의 동적인 요구 사항들을 수용할 수도 있어야 한다. 본 논문에서는 CSP(Constraint Satisfaction Problems) 해결 기법 기반의 자원 할당법을 이용함으로써 효과적으로 공간 계획 문제를 해결할 수 있도록 하였으며 사용자의 요구에 따라 변화되는 제약조건은 지능형 사용자 인터페이스 모델을 통해 좀 더 향상된 결과가 도출될 수 있도록 설계 및 구현하였다. 또한, 2차원 도면에서의 수정 요구에 대한 편이성과 시각적 검증을 위해 웹 환경 하에서의 VRML(Virtual Reality Modeling Language)을 이용한 3차원 도면을 보여준다. The spatial layout planning system allocates rectangular resources in the limited space according to user requirements. This system also can optimizes the spatial allocation problem to maximize the user's requirement. The spatial layout planning problems for this system can be solved by searching a wide area of space since this problem entails the non-polynomial algorithm. By accommodating the user's dynamic requirements, the modification of a specific space and the redesign of the whole area can be accomplished. In this paper, the spatial layout planning problem is solved efficiently with a resource allocation method based on CSP. The dynamic constraints by adding user requirements are accommodated through the intelligent user interface. The 3-D layout on the web environment by using VRML is also shown for providing for the visual verification of the 2-D layout and, thereafter, the additional modification of the 2-D layout.
