Edge detection always influenced by noise belong to the original image, therefore need use some methods to sort this issue, mean shift algorithm has the smooth function which suit for the edge detection purpose, so adopted to fade out the unimportant information, and the sensitive noise portions. After this section, use the Canny algorithm to pick up the contour of the objects we focus on, meanwhile select the Soble operator that has the orientation attribute to support the method work well. In final, take experiment and get the perfect result we wanted, make sure this method make sense and better than the sole Edge detection algorithm,

Hospital pharmacy services are divided into dispensing affairs for inpatients and outpatients, pharmaceutical service, stock control, intravenous admixture service, drug information service, pharmacokinetic consultation service, education and research work, etc. But among those affairs, dispensing affair for outpatient is perceived as the most important work in Korea, because it is linked directly with hospital service for patients. Therefore, total computer system for dispensing area was adopted from opening point of hospital in 1989 in Asan Medical Center. Utilization of computer system for outpatient dispensing area is as follows; 1) Order communication system of prescription by Total Hospital Information System, 2) Automatic print-out system of direction for use by sticker connected with on-line net work, 3) Use of automatic tablet counting and packaging machines connected with on-line net work. Those computer system resulted in curtailment of pharmacy manpower and shortening of waiting-time for outpatient.

According as many people use a computer newly, damage of computer virus and hacking is rapidly increasing by the crucial users. To block hacking that is intrusion of a person's computer and the computer virus that destroys data, a study for intrusion-detection of system and virus detection using a biological immune system is in progress. In this paper, we make a model of positive selection and negative selection of self-recognition process that is ability of T-cytotoxic cell that plays an important part in biological immune system. So we embody a self-nonself distinction algorithm in computer. To prove the efficacy of self-recognition algorithm, we use simulations by a cell change and a string change of self file.

For the purpose of adapting positively to the information society, it is very important to develop the capabilities of the retrieve, gather, process and application for informations by making efficient use of computers. So, with a view to understanding the importance of computer and adjusting actively to the information society, the systematic policy to cultivate the ability of making the most of computers is strongly demended. Therefore this study is to make a curriculum and guide for improving the capability of applying computers systematically, through analyzing a curriculum of computer in Elementary, Middle and High Schools, and to develop a model of grading system to cultivate the ability of applying computers, which grades capabilities of its practical use.

Existing large-scale complex programs usually reside In a single computer, and the user has to be physically in contact with the computer. With the wide spread use of the internet, the need to carry out the design and analysis tasks geographically away from the main computer is increasing. In this paper existing Windows-based propeller design and analysis package is separated into the server-client modules and the protocol program is developed to implement the communication between multi-client computers and a single server computer. A new protocol packet is designed to use the Windows socket and the server/client programs control the receive/send operations using the information transmitted in the packet. Test runs show that the remote user, connected to the server computer through the internet only, can perform the required tasks.

본 논문은 영유아들의 컴퓨터 활용 실태를 알아보기 위하여 컴퓨터 사용 형황을 성별 및 연령별로 설문조사를 실시하였다. 연구 대상은 1세에서 7세의 영유아들로 김포시 K대학의 유아교육과 학생들이 직접 영유아 교육기관을 방문하여 영유아들을 직접 면담하면서 설문지를 작성하였다. 분석에 이용된 대상은 남아가 177명으로 46,8%, 여아가 201명으로 53.2% 총378명의 설문지를 사용하였으며 조사 결과 남아보다 여아가 한글 읽기와 쓰기, 숫자 활동, 외국어나 음악 미술 활동 등의 교육적 목적으로 활용하는 경우가 더 많았고 만화 영화나 게임, 인터넷 검색 등에서는 남아의 활용 비율이 더 높게 나타났다. 연령별로는 1-3세에서는 한글 읽기와 쓰기가 22명(51.2%)를 차지하였고 4-5세에서는 한글 읽기와 쓰기는 28명(28.3%), 그 다음이 게임으로 22명(22.2%)로 나타났고 6-7세에서는 한글 읽기와 쓰기가 54명(22.8%), 게임이 51명(21.6%)으로 비슷하게 나타났고 그 다음이 만화영화 보기로 47명(19.9%)로 나타났다.

NUI is a motion interface. It uses the body of the user without the use of HID device such as a mouse and keyboard to control the device. In this paper, we use a Pi Camera and sensors connected to it with small embedded board Raspberry Pi. We are using the OpenCV algorithms optimized for image recognition and computer vision compared with traditional HID equipment and to implement a more human-friendly and intuitive interface NUI devices. comparison operation detects motion, it proposed a more advanced motion sensors and recognition systems fused connected to the Raspberry Pi.

Mathematics was the main domain of PISA 2012, and both paper-based and computer-based assessment of mathematics (CBAM) were conducted. PISA 2012 was the first large-scale computer-based mathematics assessment in Korea, and it is meaningful in that it evaluated students' mathematical literacy in problem situations using dynamic geometry, graph, and spreadsheet. Although Korea ranked third in CBAM, the use of ICT in mathematics lessons appeared to be low. On the other hand, this study focused on Singapore, which ranked first in CBAM. The Singapore Ministry of Education developed online programs such as AlgeTools and AlgeDisc, and implemented the programs in classes by specifying them in mathematics curriculum and textbooks. Thus, this study investigated influential factors on computer-based assessment of mathematics by comparing the results of Korea and Singapore, and aimed to provide meaningful evidence on the direction of Korea's ICT-based mathematics education. The results showed that ICT use at home for school related tasks, attitudes towards computers as a tool for school learning, and openness and perseverance of problem solving were positively associated with computer-based mathematics performance, whereas the use of ICT in mathematics class by teacher demonstration was negatively related. Efforts are needed to improve computer use and enhance teaching techniques related to ICT use in Korean math classes. Future research is recommended to examine how effectively teachers use ICT in mathematics class in Singapore.

The purpose of this study is to investigate the difference between using computers for an Information Literacy Abilities of Young Children(ILAYC) and development of the ILAYC, with regard to following factors: computer use at home, learning in educational facilities for early childhood, and parents' recognition toward computer-assisted education. The data were obtained from random sampling of 4-year old children in educational facilities for early childhood located in J city. The research was conducted in order to measure ILAYC, using the questionnaire for teachers from September 3 to 27, 2009. The t-test to investigate computer utilization ability and information literacy ability for young children revealed that the ILAYC was not significantly influenced by their computer use at home, while the ILAYC varied with learning in educational facilities and parents' recognition toward computer-assisted education. These are resulted from parents' different recognition toward computer-assisted education when they select an educational facility for early childhood.

In this paper we study the usefulness of Maple in school calculus education. The use of computer and calculator is debated in many aspect in mathematics education. By the computer visualization of mathematical image and proper use of computer we can teach inductively and intuitively the mathematical concept and give rise to the students' interest. Maple is very popular in college but is not in middle school because of language. Maple application which is made by Maplet is very useful multimedia teaching-learning tools. We introduce the use of Maplet and some application of the calculus course which we made.
