In the modern times, video media area is dramatically developing and growing. The motion graphic that is one of video presentation technique as an effective communication way between sender and receiver is beginning to make its appearance. The motion graphic provides the clearance of visual information to deliver it more easily and accurately and improves the effect of communication to increase the effect of image and information delivery. In this research, the writer wants to examine the production method of motion graphic to improve convenience and efficiency of communication to the better direction for production process by researching and analyzing the title design and its structure having short and significant information delivery and strong visual presentation function.

Korean Apartment Housing, which has been built up for short-time, represents as popular housing reflecting our unique cultural background, and recently the utility room in apartment housing has been changed to accept residents' needs, focusing on their improving life styles. At this point, the purpose of this study Is to analyze the characteristics of the utility room between 1995 and 2005 in order to grasp the current change of the utility space in Korean Apartment Housing. For this, this research investigated 176 samples, collected in 'Apartment Encyclopedia(2004)'. The major results of this study are as follows : 1) As the utility room gets bigger, the size and the ratio to the whole unit area are increased, however the ratio in small area is bigger than the ratio in other area. 2) According to time, the utility room tends to increase the size and the ratio to the whole unit area, and the Increasing tendency appears distinctively after 2002. 3) The utility room used to be located with rear balcony area, however, now it appears to be planned Independently with its unique function. 4) Currently, Second-Kitchen start to plan in the apartment housing.

The cooling characteristics of a hot steel plate by a laminar impinging water bar were investigated experimentally. The dynamic parameters investigated were nozzle height L between nozzle and the hot plate, flow rate Q, and initial cooling temperature. Because the boiling phenomena on a hot steel plate are unsteady and change discontinuously, it is difficult to analyze the cooling characteristics directly. In this study the cooling efficiency was estimated by using the temperature decay rates and expansion speed of the water cooling zone. Temperature in the water cooling zone decreased rapidly and the radius of the water cooling zone expanded nearly in proportion to square root of the cooling time. With increasing initial temperature of a hot steel plate, the cooling efficiency became descendent. The cooling curve in the case of L/D = 30 showed the largest temperature decay rate and excellent cooling performance.

Since there are no specifications in Korea regarding the design of steel column baseplates that are subjected to concentric axial load, this paper proposes a more accessible stress design method for baseplates based on AISC specifications and guidelines.Some designs included in this paper were: (1) a full area ofconcrete bearing pressure under normal axial load and subsequent failure in external cantilevers at 0.95 d or 0.8 bf, and (2) a partial area of the pressure under a light axial load and subsequent failure as an internal cantilever model.

Unmanned robot system has become a significant part of network centric warfare. Unnlike the commercial wireless system, however, it is tricky to provide reliable communication in the harsh environment: tactical and military communication. Therefore, it needs to be considered when the base station and mobile has poor communication channel. In this paper, we proposed an efficient operating algorithm for unammned robot system with ensuring communication survivability in the harsh environment. From the simulation, we adopted the SUI channel suitable for domestic mountainous area and open terrain with Rician factor K.

This paper addresses mathematics content knowledge required for teaching in secondary school. Three components of mathematical knowledge are needed for teaching: (i) knowing school mathematics, (ii) knowing process of school mathematics, (iii) making connections between school mathematics and advanced mathematics. We investigated mathematics content knowledge of secondary teachers. We found that secondary mathematics teachers have a lack of understanding in solving realistic problem, reasoning and proof, and making connections between school mathematics and advanced mathematics.

The reaction of hydration proceeded at the same time the vapor was introduced into the reactor that was filled with calcined dolomite. It has shown that the temperature has begun to fall from the bottom of reactor after increase of temperature by the heat of hydration reaction. The reaction initiated at the pipe wall and the heat was transfer to the center of block between the fins. The results show that the use of copper fin in the reactor reducted the hydration reaction time by half when compared to the case without using the fins.

문헌정보학 전공자에게 있어 취업의 꽃은 대학도서관 사서로의 진출이 아닐까 싶다. 왜냐하면 대학 도서관은 다른 관종의 도서관에 비해 외형적으로 규모가 크고, 업무는 다양할 뿐만 아니라 영역별로 전문화되어 있어 다양한 경험을 쌓을 수 있는 장점이 있다. 게다가 근무시간이나 급여, 복지 등과 같은 근무조건 및 환경 역시 타 관종에 비하여 비교적 우위에 있다고 하겠다. 때문에 전공자들 사이에는 기회가 된다면 누구나 대학도서관 사서로의 꿈을 꾸는 것이다. 하지만 최근 대학을 둘러싼 내외적인 상황이 그리 만만하지가 않다. 대학 외적으로는 대학 간 무한경쟁 체제의 확산 및 심화, 입학자원의 절대적 감소, 정부 및 각종 기관의 지원시 엄격한 평가 적용 등의 영향과 내적으로는 대학내 도서관 위상의 점진적 약화, 사서적인 수의 감소, 사서직에 대한 전통적 인식 약화로 인한 입지 위협 등으로 인하여 대하교직원 채용에 있어 도서관 사서는 대개 후순위이거나 고려대상에서 점점 더 멀어지고 있는 실정이다. 또한 최근에는 긍적적 측면과 부정적 측면이 상존하는 사서직원의 본부부서 이동 역시 늘어나고 있다고 하겠다. 한편 1987년 사서자격증 발급자가 2,000여명을 돌파한 이래 최근에는 매년 2,400여명 내외의 자격증 소지자를 배출하고 있는데, 본 글은 이 정도의 공급에 미루어 볼 때 전체 관종 대비 대학도서관 사서의 모집현황은 어느 정도인지? <사서e마을> 정규직, 비정규직 코너에 2007~2010년간 게재된 모집 공고 중심으로 월별, 지역별, 대학 설립주체별 현황 분석 및 전망을 해보고자 한다.

The purpose of this paper is to examine a user's flow experience of digital contents. In the paper, the flow experience of digital contents was applied to the case of online games and it was experimentally investigated whether challenge and skill affect the user's flow experience. The results of the paper indicate that there are differences in the flow experience according to the level (low, medium, high) of challenge and skill in the context of online games. Furthermore, there is no interaction effect between challenge and skill affecting flow experience. The findings provide useful implications for IT firms that will plan to develop and design digital contents.

생명공학은 기술의 특성상 보건 의료, 농업, 자원 환경, 에너지 등 광범위한 산업에 응용될 수 있는 고부가가치형, 두뇌기술집약형, 탈공해형, 자원 및 에너지절약형 기술이라는 특징을 지니고 있어 21세기 미래산업을 선도할 것으로 기대되고 있다. 본 연구의 목적은 생명공학기술이 1980년과 1990년 사이의 산업구조에 어떠한 변화를 초래하였는지를 알아보는 것이다. 생명공학의 산업경제적 파급효과를 분석해 보기 위해 한국은행에서 발행한 산업연관표를 이용하여 생명공학 관련산업의 지원에 따른 국내 제반산업의 생산변화율을 측정하였다. 정부의 지원이나 금리 및 세제의 혜택을 통해 생명공학 산업 관련 비용이 감소하게 되면 이에 따른 가격변화가 국내 산업발전과 고용의 증가를 갖는 것으로 믿어진다. 고정계수 아닌 변화계수를 특징으로 하는 본 모형의 접근방법은 생명공학에 대한 재정지원 및 세제 인센티브 등을 외생변수로 처리하여 산업구조 변화의 추이와 고용유발 등을 예측하였다. 본 논문의 가설은 생명공학의 영역이 점차 증대되어 나아가기 때문에 1980년의 제반산업의 영향은 1990년의 영향보다는 적어야 한다. 즉 생명공학 관련비용 하락이 전체산업에 미치는 1980년의 생산율 증가보다 1990년의 생산율 증가가 커야 할 것이다. 본 가설에 대한 검증의 과정에서 얻은 통계치를 통해 생명공학산업이 한국 산업 전체에 미치는 영향이 10년 동안에 그 차이가 거의 없어 미성숙 단계에 있다는 결론을 짓게 되었다. 따라서 생명공학 분야의 계속적인 발전을 위해서는 선진국 수준의 독자적 기술개발을 통한 국제 경쟁력을 강화해야 하는데 이를 위한 정부 및 민간기업 투자확대와 연구개발 지원체제의 확대가 요망되고 있다.
