The purpose of this study is to investigate common errors made by Korean learners in English composition and to find out what is an effective and appropriate teaching method of English composition in Korea. For these purposes, 197 students on the third grade in high school were selected as the subjects of this research. The students were tested by way of the immediate translation of 31 simple Korean sentences into English which are supposed to be easy for those students to write without any difficulty. About 2 minutes were given for testing each sentence. The results are as follows : First. the whole sum of errors made by 197 students was 2,972 and these types of errors were classified into 13 categories by Duskova's grammatical method and James'. The errors with comparatively high frequency were prepositional errors(17.2%), verbal errors(15.4%), and the errors with low frequency were article errors(1.9%), to-infinitive errors. Second, when Korean students learn English as a target language, overgeneralization(33.6%) and reduction(17.5) influenced the learners much more greatly than language transfer(22.2) did. But the influence of language transfer including interference & overgeneralization(l5.2%) and interference & reduction(10.7%) was no less than 48.1%. The statistics shows that the learners have a tendency to analyze, systematize and regularize the target language when they start to learn a new language.

Until now, many networked robots have been connected to the Internet for the various applications. With these networked robots, very long distance teleoperation can be possible through the Internet. However, the promising area of the Internet-based teleoperation may be distance learning, because of several reasons such as the unpredictable characteristics of the Internet. In robotics class, students learn many theories about robots, but it is hard to perform the actual experiments for all students due to the rack of the real robots and safety problems. Some classes may introduce the virtual robot simulator for students to program the virtual robot and upload their program to operate the real robot through the off-line programming method. However, the students may also visit the laboratory when they want to use the real robot for testing their program. In this paper, we developed an Internet-based robot education system. The developed system was composed of two parts, the robotics class materials and the web-based Java3d robot simulator. That is, this system can provide two services for distance learning to the students through the Internet. The robotics class materials can be provided to the student as the multimedia contents on the web page. As well, the web-based robot simulator as the real experiment tool can help the students get good understanding about certain subject. So, the students can learn the required robotics theories and perform the real experiments from their web browser when they want to study themselves at any time.

In the 1990s, university environment is changing rapidly(especially, difficulty of student registration which are originated student's decrease and various deregulation) and university get ready for the new ways of management culture. This new ways are management innovation strategies. The purpose of this study is to suggest the direction of effective innovation(to search application possibility of management innovation strategy), solving the problems occurred by the enlargement and change in the environments of universities. From early in the 1990s, korean corporations perform actively many management innovation strategy including benchmarking, restructuring, downsizing, zero-based budgeting, BPR, learn organization and total quality management. But korean most universities performed hardware management innovation strategies such as corporate portfolio restructuring(including outsourcing, M&A, MBO etc.) and organization restructuring. Therefore korean universities have got to concerns about more software management innovation strategy such as total quality management and learn organization. Also we have seen another problems such as that universities try to merely duplicate certain management innovation strategies which are used by another university. rather than to make various effort to adequate their own organizations. In conclusion, korean universities are to play an important roles in the development of knowledge society. The management innovation and individual competence development in the university are required to overcome crisis of university.

The study was aimed to estimate the degree of recognition of, satisfaction with and needs for cooking practice education. 300 female students of middle schools and high schools in Seoul, Kyung-gi, Inchon area were targeted fer the research, which has been conducted from January 1st to December 20th in 2003. The crosstab, the t-test, and the ANOVA analysis were processed as methods using SPSS. The study showed that most of students had experienced cooking exercises, and the degree of satisfaction of the high school group was higher than that of the middle school group. Both groups answered they wanted more time for the cooking practice classes and the middle school group had the greater necessity. The necessity far practice lessons of cooking traditional foods reaches n high level in both groups, All the students answered they liked both western and traditional foods, but preferred the traditional food to the western one. They also believed the traditional food was more healthy than the western one. In terms of the needs for cooking practice education, the middle school group wanted to learn how to cook cake, pie, steak potato chip, and hamburger, while the high school group wanted cake, pie, steak sandwich, and potato chip. As for the traditional food, the middle school group wanted to learn how to cook Naegmyun(cold noodles), fried rice, rice hash, dumpling soup, and knife-cut noodles. The high school group, however, picked knife-cut noodles, fried rice, iced noodles, rice hash, and rice-cake soup.

In general, small-sized neural networks, even though they show good generalization performance, tend to fail to team the training data within a given error bound, whereas large-sized ones learn the training data easily but yield poor generalization. Therefore, a way of achieving good generalization is to find the smallest network that can learn the data, called the optimal-sized neural network. This paper proposes a new scheme for network pruning with ‘impact factor’ which is defined as a multiplication of the variance of a neuron output and the square of its outgoing weight. Simulation results of function approximation problems show that the proposed method is effective in regression.

The main objective of this study is to examine the required aptitudes for undergraduate students who want to join export-oriented Small & Medium Enterprises(SMEs). 178 Dataset from a survey of exporting firms in Gwangju, Korea, were used to analyze the study. The results of the study are as follows ; First, the most required aptitude is 'the capability related to build up human relationship'. So students should learn negotiation skills in the college. In addition to this, student also try to join informal club and cultivate teamwork capabilities. Second, finding out a job in export-oriented SMEs is needed to equip with problem-solving capabilities. To do it, students should learn various subjects related to trade theory. Additionally, having some certificates like 'international trade master' can be better. Third, communication capabilities including foreign language and international business skills will be also required for students who are preparing for joining export-oriented SMEs. However, capabilities related to information technology and basic statistic skills does not have statistically significant correlation to recruitment intention. As a result, students who have such above-mentioned four aptitudes may have better position to find out jobs in export-oriented SMEs.
