Computer Science Unplugged is a collection of free learning activities that teach Computer Science through engaging games and puzzles that use cards, string, crayons and lots of running around. In spite of the success of unplugged activities, the unplugged resources for experiencing the concepts of data structures is lacked. In this study, we design, implement and survey the 3 hour lessons of the core concepts of graph theory and the shortest path algorithm for the primary students using computer science unplugged activities. Our survey results showed that our lesson plan is adequate for primary school students and will have a positive effects for primary school students.

Computer based instruction in the elementary science curriculum will be played an important role through the fifth curriculum reform from the 1989 school year. This is essential for the science instruction because the strategies on the problem-solvings and inquiry approaches can be utilized for the science classroom. Computer education can be thought as the education about the computer and the education using the computer. Of them the education using the computer means the computer assisted instruction(CAI) what is called all the possible activities using the computer in the classroom. Student achievement as the result of CAI depends on the learning activities of students and the instructional techniques and strategies of teachers using the computer. However, computer based education to enhance the student achievement is pointed out the lacks of the standardized Korean alphabet code and the compatibility of qualified software. These problems will be relieved according to the coding for the Korean alphabet of SUPER PILOT program language.

This study compared the electromyographic activities and input performance of computer operators using a computer mouse and a trackball. Muscle activities were assessed at the upper trapezius (UT), middle deltoid (MD), extensor digitorum (ED), and first dorsal interosseous muscle (FDI). Twenty-six healthy subjects were recruited, and the test order was selected randomly for each subject. The task set was to click moving targets on a Windows program. The EMG amplitude was normalized using the percentage of reference voluntary contraction for UT and MD and the percentage of maximal voluntary contraction for ED and FDI. To analyze the differences in EMG activity, a paired t-test was used. UT muscle activities were significantly greater when the computer mouse was used (p<.05). FDI muscle activities were significantly greater when the trackball was used (p<.05). Using a trackball can reduce the load on the UT during computer work and help to prevent and manage work-related musculoskeletal disorders.

Recent interest in software education has naturally led to interest in computer science. Computer science is the study of theory and principle of computer and computational systems. This knowledge and concept of computer science is fundamental to software education. Recently, "Computer Science (CS) Unplugged", which is an educational method for introducing students to concepts of computer science without using a computer, has been widely used in classes around the world. CS Unplugged is a method for learning the basic principles of computer science through diverse playing activities. The problem, however, is that these CS unplugged activities take place in class without an analysis of how closely they relate to the core subjects learned in real computer science. Therefore, in this study, we will study on the comparison between the core contents of computer science and the core contents of computer science contained in the various activities of CS Unplugged.

The purpose of this study is to develop and applicate the computer science teaching-learning program to raise the next newest talented students in IT field. The experiment was conducted to analyze the effects of learners variables such as learning achievement and attitude at K elementary school in Chungcheongbuk-do during 8 weeks and samples were 74 students. The summary of results of this study are as follows : First, significant differences were not observed in part of achievement of learning between comparative group and the experimental group who used computer science program consisted of specific manipulative activities. However, the higher mean score means that teaching-learning based on specific manipulative activities have a positive effect on understanding contents of computer science. Second, it is found that students in experimental group respond more positively about computer science than comparative group.

DESIGNIN AND OPERATION OF DIGITAL EVIDENCE MANAGEMENT SYSTEM APPLYING COMPUTER FORENSICS AND ELECTRONIC CERTIFICATION Digital evidence will be used as a term, which means the electronic form of information which is necessary to confirm or prove the factum of all kinds of behaviors committed through the devices which have data processing ability including computer. It is expected that there will be the increase of legal conflicts surrounding electronic commerce activities as well as the increase of cyber crimes, as the number of Internet users are getting bigger. In order to solve the problems of conflicts derived from electronic commerce, the factum of electronic commerce activities must be confirmed. In order to confirm the factum of electronic commerce activities, the evidence is prerequisite. Almost all evidences relating to the electronic commerce activities exist in digital form. For the reason that the digital evidence can be easily damaged and changed, special management is required to collect, analyze, and preserve the digital evidence. In order to meet this requirement, this study proposes a basic model of digital evidence management system applying computer forensics and electronic authentication.

Teaching materials are an important aspect to decide the quality of education. Science teaching materials include textbook, workbook, worksheet, OHP materials, posters, computer softwares, experimental equipments, slides, video tapes, and other audio-vidual materials. This comparing research is based on the contemporary teaching materials used in elementary schools of the United States and Korea in 1990s. The results of this study are : 1. The United States has more elementary science teaching materials such as posters, worksheets, computer softwares, OHP materials than Korea. Both countries developed elementary science textbooks, activity books, video tapes, science reading materials, and experimental equipments. 2. The frequancy of using these science teaching materials in Korea is bigger than that in the United States. In Korean elementary science classes, most of instructions are progressed by experimental activities. Korean elementary science textbooks are mostly consisted of science activities, but those of the United States includes science information, science related jobs, STS articles and some portion of science activities. 3. Experimental equipments of the United States are stronger than those of Korea. Various and excellent elementary science teaching materials such as computer softwares, posters, audio-vidual materials, and experimental equipments should be developed and used in elementary science classes for better elementary science education.

Workflow process mining is becoming a more and more valuable activity in workflow-supported enterprises, and through which it is possible to achieve the high levels of qualitative business goals in terms of improving the effectiveness and efficiency of the workflow-supported information systems, increasing their operational performances, reducing their completion times with minimizing redundancy times, and saving their managerial costs. One of the critical challenges in the workflow process mining activity is to devise a reasonable approach to discover and recognize the bottleneck points of workflow process models from their enactment event histories. We have intuitively realized the fact that the iterative process pattern of redo-activities ought to have the high possibility of becoming a bottleneck point of a workflow process model. Hence, we, in this paper, propose an algorithmic approach and its implementation to discover the redo-activities and their performers' involvements patterns from workflow process enactment event logs. Additionally, we carry out a series of experimental analyses by applying the implemented algorithm to four datasets of workflow process enactment event logs released from the BPI Challenges. Finally, those discovered redo-activities and their performers' involvements patterns are visualized in a graphical form of information control nets as well as a tabular form of the involvement percentages, respectively.
