Considering teaching methods for computer education is a must for effectively instructing students of knowledge and skills on computers. In this paper, we adopts STAD Cooperative Learning method, among many others, in order to reduce any burden teachers and learners may have. As a result, it finds out that practical training based on STAD Cooperative Learning is very effective in enhancing students' abilities for ICT data collection and manipulation. The teaching model driven out as a result of this study, will be a good example for teaching models in many computer-related departments. In the future, more studies on teaching models will have to take place for more effective teaching of computer courses.

This paper discusses distributed processing systems to be applied to design the Education and research Computer Network. Especially, we have analyzed performance measures of computer communication networks, have solved the capacity assignment problem approximately, and have presented two algorithms by which we could decide the efficient topology of a computer communication network. In general, computer networks can be modelled by appropriate queueing models on the basis of queueing theory. But in that case we must consider several performance measures carefully to estimate the performance of the model of a computer network. In this paper, we have analyzed some important performance measure - time delay, line cost, and routing strategy. According to queueing theory, we can get optimal solutions of the network optimization problems. However, if we are to use this method we should know a great deal of data, and so it is time-consuming to find the analytic optimal solutions. In this paper, we have introduced the inefficient index(I) to describe another method - approximate method - of solving the capacity assignment problem. Meanwhile, we have presented two algorithms by which the efficient network topology can be extracted. In other words, this paper has shown construct the Education and Research Computer Network, which is one of the Five Main National Computer Networks, and we can expect it might be applied to the implementation of other computer networks. the design method of the network topology satisfying suitable utilities and costs of processors, which are components of a computer network, under the given design constraints. With applying those algorithms to the computer network including several distributed database systems, we have presented a case study. In conclusion, this paper has provided a theoretical background to

Studies have suggested that the writing process is a mixture of lowand high-level processing for multiple level decision making, which is performed either during pauses or motor execution. Some studies have found that high-level processing is mostly conducted during pauses, but when high-level processing is performed in parallel with motor execution, it is called parallel processing. The purpose of this study is to examine parallel processing in computer-based L2 writing and to identify types of high-level processing concurrent with typing. This study analyzed keylogging data of the L2 English writing of three different proficiency groups and found that only advanced L2 writers were able to perform parallel processing. The parallel events in L2 writing mainly include two components: linguistic and conceptual processing. Linguistic processing is mostly performed in translating episodes where a writer translates one’s ideas into L2 and evaluates the translation in terms of adequacy and acceptability. Also, advanced L2 writers engage in conceptual processing concurrently with typing, mostly at the ideational and epistemic/rhetorical levels. It is hoped that this study will prompt future studies to investigate the real-time process of writing and provide insights on parallel processing in L2 writing.

We have developed a microprogramir!able signal processor for real-time ultrasonic signal processing. Processing speed was increased by the parallelism in horizontal microprogram using 104bits microcode and the Pipelined architecture. Control unit of the signal processor was designed by microprogrammed architec- ture and writable control store (WCS) which was interfaced with host computer, APPLE- ll . This enables the processor to develop and simulate various digital signal processing algorithms. The performance of the processor was evaluated by the Fast Fourier Transform (FFT) program. The execution time to perform 16 bit 1024 points complex FF7, radix-2 DIT algorithm, was about 175 msec with IMHz master Clock. We can use this processor to Bevelop more efficient signal processing algorithms on the biological signal processing.

The explosion in biological data resulting from high-throughput experiments requires new software tools to manipulate and display pathways in a way that can integrate disparate sources of information. A visual Java-based CAD tool for drawing and annotating biological pathways with semiautomatic image-processing features is described in this paper. The result of the image-editing process is an XML file for the appropriate links. This tool integrates the pathway images and XML file sources. The system has facilities for linking graphical objects to external databases and is capable of reproducing existing visual representations of pathway maps.

Recently, methodologies for developing brain-computer interface (BCI) games using the BCI have been actively researched. The existing general framework for processing brain waves does not provide the functions required to develop BCI games. Thus, developing BCI games is difficult and requires a large amount of time. Effective BCI game development requires a BCI game framework. Therefore the BCI game framework should provide the functions to generate discrete values, events, and converted waves considering the difference between the brain waves of users and the BCIs of those. In this paper, BCI game frameworks for processing brain waves for BCI games are proposed. A variety of processes for converting brain waves to apply the measured brain waves to the games are also proposed. In an experiment the frameworks proposed were applied to a BCI game for visual perception training. Furthermore, it was verified that the time required for BCI game development was reduced when the framework proposed in the experiment was applied.

This paper deals with a parallel processing uninterruptible power supply (UPS) for sudden voltage fluctuation in computer applications to integrate power quality improvement, load voltage stabilization and UPS. To reduce the complexity, cost and number of power conversions, which results in higher efficiency, only one voltage-controlled voltage source inverter (VCVSI) is used. The system provides sinusoidal voltage at the fundamental value of 220V/60Hz for the load during abnormal utility power conditions or grid failure. Also, the system can be operated to mitigate the harmonic current and voltage demand from nonlinear loads and provide voltage stabilization for loads when sudden voltage fluctuation occur, such as sag and swell. System operation simulation demonstrates that the system protects against outages caused by abnormal utility power conditions and sudden voltage fluctuations and changes.

원자로 내에서 연소 중인 핵연료나 저장 또는 재처리 중인 사용후핵연료의 성분으로서 시설의 공정설계, 안전성분석 및 차폐설계에 중요한 입력자료가 되는 핵분열생성물질, 방사화생성물 및 악티나이드의 핵종 농도와 이에 대응하는 방사능 강도의 기기 별 시간변 화율을 해석할 수 있는 코드 개발할 목적으로 MULTISAMS 정상 평형상태 모델을 구현하였다. MULTISAMS 코드의 반응공정 모델은 서로 연결되어 있으며 내부에 방사성물질의 혼합유체가 순환하는 세 종류의 반응기(원자로, 열교환기 및 화학반응기) 계통에서 자연적 또는 설계에 의해 일어나는 현상으로서; 반응기 간의 물질 흐름; 각 반응기 내에서 방사성 붕괴, 변환, 이동과 중성자 흡수 및 핵분열; 외부로부터 특정 핵종의 유입혹은 유출을 고려한 시간종속 핵종농도보존방정식 이론에 근거한다. 코드의 유용성 및 신뢰성을 검증하기 위해 현재 개념설계가 진행 중인 AMBIDEXTER원자력 에너지시스템을 대상으로 ORIGEN2 계산과 비교하였다. 두 코드 간의 입력조건과 배경이론차이점 때문에 절대적 비교가 불가능하므로 단순이론의 중간매개코드로서 SAMS를 이용한 2단계 비교방법을 따랐다. 결론은 MULTISAMS는 ORIGEN2 계산의 수렴치와 근사하게 일치하면서 ORIGEN2 가 다룰 수 없는 핵주기 연속후처리공정의 정상가동 시 핵종 평형농도를 기기 별로 계산할 수 있다는 장점을 확인하였다.

This paper suggests the navigation information display system which is based on augmented reality technology and especially focuses on image analysis technology. Navigator has to always confirm the information from marine electronic navigation devices and then they compare with the view of outside targets of the windows. During this 'head down' posture, they feel uncomfortable and sometimes it cause near-accidents such as collision or missing objects, because he or she cannot keep an eye on the front view of windows. Augmented reality can display both of information of virtual and real in a single display. Therefore we tried to adapt the AR technology to help navigators and have been studied and developed image pre-processing module as a previous research already. To analysis the outside view of the bridge window, we have extracted navigational information from the camera image by using image processing. This paper mainly describes about recognizing ship feature by haar-like feature and filtering region of interest area by AIS data, which are to improve accuracy of the image analysis.

To quickly and accurately grasp the consistency and the true/false of sentence description, we may require the help of a computer. It is thus necessary to research and quickly and accurately grasp the consistency and the true/false of sentence description by computer processing techniques. This requires research and planning for the whole study, namely a plan for the necessary tables and those of processing, and development of the table of the five logic rules. In future research, it will be necessary to create and develop the table of ten basic inference rules and the eleven kinds of derived inference rules, and it will be necessary to build a DB of those tables and the computer processing of sentence logic using server programming JSP and client programming JAVA over its foundation. In this paper we present the overall research plan in referring to the logic operation table, dividing the logic and inference rules, and preparing the listed process sequentially by dividing the combination of their use. These jobs are shown as a variable table and a symbol table, and in subsequent studies, will input a processing table and will perform the utilization of server programming JSP, client programming JAVA in the construction of subject/predicate part activated DB, and will prove the true/false of a sentence. In considering the table prepared in chapter 2 as a guide, chapter 3 shows the creation and development of the table of the five logic rules, i.e, The Rule of Double Negation, De Morgan's Rule, The Commutative Rule, The Associative Rule, and The Distributive Rule. These five logic rules are used in Propositional Calculus, Sentential Logic Calculus, and Statement Logic Calculus for sentence logic.

Historical coding is the first step in acquiring basic knowledge to start digital history, but it has practical potential to be used in research and educational activities of professional historians. In the field of historical research, the principle of coding has the function of organizing historical data and creating specific contexts and meanings. In particular, the advantage of historical coding in the field of research is that it is possible to reconstruct a large amount of historical data into visual data through coding to newly grasp the contents of historical data itself. On the other hand, in the field of history education, simple causal principles can be applied along with the processing of historical data to help students understand historical events. This study reconstructed historical data containing Hitler-Jugent's activities and scale in Hamburg City before the outbreak of World War II by applying the principle of coding, and explains Hamburg citizens' attitudes toward the Nazis, which were previously difficult to grasp. This study aims to introduce a new method of coding in the way of historical research, not just to reveal the appearance of the German local government's post-Nazi movement based on the activities and scale of Hitler Eugent in Hamburg.
