This essay suggests frame of analysis about MMORPG and analyzes 3 representative games. That frame has 7 categories and more divisional analysing ietms. The 7 categories are community orientation, PK orientation, convenient usability of item, variety of character, balance, convenience of interface, aesthetics of graphic and sound. The result of analysis is quite correspond with empirical and general information. That is, Foreign games have multiple game factor and high asthetics of graphic and sound, Domestic games have good convenience of interface and well adapted balance.

Measuring tray as a component in irrigation control system using drainage electrodes was designed and applied for tomato perlite bed culture, and the effectiveness of the irrigation control system was investigated in terms of cultural development and cultivation costs. Five different types of measuring trays equipped with drainage electrodes were tested and the traditional tray was used as the control equipped with time clock. After the first experiment, "Tube-2" was removed because of instability of water content in the substrate. After second experiment, "Tube-1" was removed because of instability of water content in the substrate and low plant yields. In third experiment, "Up-Board" exhibited the best stability in water contents and yields as well as efficiencies in water and fertilizer utilization. The "Up-Board" was the most economical and the easiest system among the tested trays. Therefore, the "Up-Board" system was concluded as the excellent design to apply for the control method using drainage electrodes for tomato perlite bed culture.

The image that reflects the lapse of time can only take the form of segmentation originally. All of the fixation status in an image is shown to us as the form of division(segmentation) whether it is the form of two dimensional paintings or three dimensional sculptures, but not the form of video monitors. This kind of method was extremely developed in the cartoon field. Therefore, the cartoon evolves the subjects of events and finds the worth and meaning through the arrangement of cuts. Also, Animation inquires into the principles of attaching the media continuously. The media is represented in the segmentation according to the lapse of time and I tend to analyze the origination of cartoon formation. Consequently, I tired to find the examples of the prehistoric cuts and forms, the divisions of fragmented cartoon stripes, and the cuts and forms which are composed of narrative and descriptive styles of arrangement, and finally can certify and validate them. In summary, the sections and divisions of the variable kinds of cuts and frames for the expression of the time were corroborated. The potentials of the space usage and the diversity of the cartoon formation were also founded and illustrated to suggest the broader stands of cartoon.

Population dynamics in the vermicomposting bed was investigated. And harvesting efficiencies of earthworm attracting traps with different attractants, mesh sizes of net and covering materials was evaluated. Peak density of earthworm population was $5kg/m^2$ and therafter its desity kept $4.4{\sim}5.0kg/m^2$. It was evaluated that suitable mesh size of the net was 7mm and proper covering materials of the earthworm attracting trap was cotton quilt. The earthworm harvesting efficiency of trap with attractant was much higher than that of trap without attractant. With more amount of attractant in the trap and with longer setting period of trap onto the vermicomposting bed, the earthworm attracting trap harvested more earthworms. Crushed pear-peel attracted much more earthworms than paper mill sludge, but it was difficult to supply enough amount of crushed pear-peel for practical need. Sugar solution(10%) with tab water was proven to be an alternative to crushed pear-peel because its attracting effect on earthworm was as high as crushed pear-peel and it was easy to prepare and supply in large quantity.

This study aims to develop a framework of structural scenarios for chatbot docent that supports visitors' activities in science centers and museums, and to suggest the application examples. For this study, the author adapted Focus Group Interview. As a result, the frameworks of scenarios could be categorized into the Collection of Science and Technology(CST) and Inquiry-Based Exhibition(IBE). These frameworks had dimensions of the primary and storytelling in common. Especially, framework of IBE scenario was added the usage dimension considering the characteristics of interaction between exhibits and visitors. This study could be basic materials for AI chatbot to support exhibition descriptions using the built data, and is expected to be help develop a more visitor-oriented scenarios of activities.

과학교육에서 효과적인 과학 수업을 위하여 과학사 도입의 중요성이 계속 강조되어 왔다. 이에 따라 과학 교과서에는 많은 과학사 자료가 사용되고 있다. 하지만 과학 교과서에 사용된 과학사 자료가 어떤 유형과 맥락에서 어떠한 역할을 하고 있는 지에 대한 면밀한 분석은 이루어지지 못한 실정이다. 이에 본 연구에서는 선행 연구와 관련 문헌 분석을 통해 과학 교과서에 사용된 과학사 자료를 분석하기 위한 3차원 틀을 개발하고, 이를 제 7차 교육과정의 과학 교과서 지구과학 내용을 대상으로 적용하였다. 개발된 분석틀은 수업맥락, 역할, 제시유형의 3개 차원으로 구성된다. 수업맥락 차원은 흥미, 사회-문화적, 인식론적, 개념적 맥락의 4가지 영역으로 세분되며, 제시유형 차원은 에피소드/일화, 발견/고안, 선형적인 발전, 역사적 실험의 4가지 영역으로 세분된다. 역할 차원은 기본적, 보충적, 탐구적의 3가지 영역으로 세분된다. 개발된 3차원 분석틀을 적용하여 과학 교과서의 지구과학사 자료들을 분석한 결과, 수업맥락 차원에서는 개념적 맥락의 과학사 자료가 모든 학년별 과학 교과서에서 가장 많았다. 역할 차원에서는 기본적 역할이 압도적으로 많았으며, 탐구적 역할의 경우에는 매우 적었다. 제시유형 차원에서는 발견/고안과 선형적인 발전 유형이 대부분이었고, 에피소드/일화 유형의 자료는 주로 흥미 맥락과 연계되어 극히 일부만 사용되고 있었다. 3차원 각 영역들을 48개의 조합으로 분석한 결과, '개념적 수업맥락-기본적 역할-발견/고안 유형'과 '개념적 수업맥락-기본적 역할-선형적 발전 유형' 2개 조합에 집중되었으며, 나머지 조합들의 빈도는 매우 낮았다. 전체적으로 3차원 분석틀 각 영역에 부합하는 과학사 자료가 과학 교과서에 다양하게 포함되지 못하고 일부 영역에만 집중되는 것으로 나타났으며, 이러한 연구 결과는 앞으로 다양한 수업맥락, 역할, 그리고 유형으로 과학사 자료들이 개발될 필요가 있음을 시사한다.

The purpose of this study is to evaluate the breast tool to improve the diagnostic value of the image in the breast examination. Breast tool was made of using FRP. And then it was compared by radioactivity counting rate and image. In the evaluation of the Breast tool, the left and right counts per $1{\mu}Ci$ are 185 counts and 189 counts, respectively. The image obtained in the prone position was close to the circle. To increase diagnostic value of image, it is considered to use Breast-tool in the breast examination.
