This study aimed to explore the potential use of artificial intelligence in science education for gifted students by analyzing the structure of abstracts written by students at a gifted science academy and comparing the performance of various elements extracted using AI. The study involved an analysis of 263 graduation theses from S Science High School over five years (2017-2021), focusing on the frequency and types of background, objectives, methods, results, and discussions included in their abstracts. This was followed by an evaluation of their accuracy using AI classification methods with fine-tuning and prompts. The results revealed that the frequency of elements in the abstracts written by gifted students followed the order of objectives, methods, results, background, and discussions. However, only 57.4% of the abstracts contained all the essential elements, such as objectives, methods, and results. Among these elements, fine-tuned AI classification showed the highest accuracy, with background, objectives, and results demonstrating relatively high performance, while methods and discussions were often inaccurately classified. These findings suggest the need for a more effective use of AI, through providing a better distribution of elements or appropriate datasets for training. Educational implications of these findings were also discussed.

This study examined the qualities of an effective teacher needed to accomplish educational reform successfully and prepare for a rapidly changing knowledge-based society. To achieve the purpose of the study, the following specific questions were looked into; (1) knowledge, skills, attitude of an effective teacher. (2) a proposal for staff development programs to improve the effectiveness of teachers. (3) a proposal to support teachers' efforts to improve their effectiveness. (4) the factors inhibiting the improvement of teachers' effectiveness. In this study, 'in-depth interview' was used for data collection because the study deals with the "subjective consciousness" of teachers, and qualitative research methods are useful to such a case. The research was done on teachers from secondary schools in Pusan City. According to the teachers interviewed, an effective teacher needed in the new age has such knowledge, skills, and attitude as; (1) knowledge in their major, general culture and common sense, psychology of educational counselling, social science, and knowledge and information related to curriculum. (2) effective instruction skills, skills to guide student behavior, skills related to administrative clerical work, using the computers, extra curriculum activities, educational evaluation, using teaching materials, developing educational programs, and good communication skills. (3) attitude relevant to willingness to understand and converse with students at their cognitive level, positive expectations and concern toward students, democratic problem solving, continuous self-study and development, thoroughgoing mission and professionalism, will for educational reform and innovation, neat appearance and refined language, and successful interpersonal relationships. The teachers also said that the current staff development system, as a program to provide necessary qualities for teachers, has improved in the last 3 years through diverse curriculum and systematic programs. However, due to the problematic promotion system, the staff development program has turned into just a 'point collecting' game from the role of in-service training program; teachers take training courses as the means just collecting points for promotion purpose. Factors inhibiting the improvement of teachers are (1) overload of formal paperwork over emphasizing outcome, (2) mannerism of teachers not perceiving their lack of professionalism, (3) the general attitude in the teaching profession resisting change and reform, (4) supervisory activities lacking rigid regulation, (5) research just as the means of point-collection only for promotion, and (6) staff development programs lacking efficiency. These factors, interacting each other, inhibited the improvement of teachers.

Named entity recognition is to classify elements in text into predefined categories and used for various departments which receives natural language inputs. In this paper, we propose a method which can generate named entity training corpus automatically using knowledge bases. We apply two different methods to generate corpus depending on the knowledge bases. One of the methods attaches named entity labels to text data using Wikipedia. The other method crawls data from web and labels named entities to web text data using Freebase. We conduct two experiments to evaluate corpus quality and our proposed method for generating Named entity recognition corpus automatically. We extract sentences randomly from two corpus which called Wikipedia corpus and Web corpus then label them to validate both automatic labeled corpus. We also show the performance of named entity recognizer trained by corpus generated in our proposed method. The result shows that our proposed method adapts well with new corpus which reflects diverse sentence structures and the newest entities.

In Korea, the major of international trade and business introduced in the 1960s to supply trade expert to trading companies, and the heyday of the trade major was in the 1980s. However the trade major fell into decay from the middle of 1990s. The purpose of trade education in university is to supply high qualified employees to societies and companies. The problem is that companies have difficuties for recruiting of trade expert, on the other hand university graduates have few job oppertunies. It has some discrepancies between education and field. The object of this paper is to propose a direction of modification of the trade and international business curriculum for global trade expert. We research international trade and business departments' curriculums of GTEP universities. GTEP stands for global trade expert incubating program started from 2006 which have charge of MOCIE and KITA. First, in the title of department, a lot of former researchers have taken up the position to return "Trade" or "International Trade". We think more important fact is not the title of department but the curriculum, so we insist on a harmony between the department title and curriculums. The focus of modification of curriculum is to educate global trade expert, so we need to know about global business environment and companies' needs also. Second, We propose the directions for modification of curriculum are "convergence" and "specialty". Trade major is a mixed study in nature and trade major try to treat lots of subjects such as trade, business adminstration, economics, international law, international commerce, logistics and marketing etc to catch up changing global business circumstanses and companies' needs. So convergence of adjacent field is very important in study and training. Specialty means selection and concentration strategy for global trade expert. It is difficult to learn every knowledge and skills for employer's needs in 4 years and 140 credits. A students who has studied basic subject in trade, management, economics can choose 1 or 2 specailty subject such as trade and e-commerce, global marketing, logistics and transportation, commerce and policy, servive trade, foreign language and cross culture etc. In concusion, the concept of convergence and specialty is not separation but harmony each other, so we propose to promote two concept together for modification of the trade and international business curriculum for training of global trade expert.

This is the research on the correlation between the marketing activities conducted by the companies participating in the overseas exhibitions in the exhibition and the satisfaction of the visitors. I have been able to obtain the following findings through the positive research on the satisfaction of the visitors to the overseas exhibitions. The research findings show that the external elements of the participating companies such as 'external appearances of booths, interior facilities and the atmosphere', 'designs of exhibits', 'size of the participating companies', and the publicity elements of the participating companies such as 'the degree of application of mass media', 'prior publicity of the participating companies', etc. among the marketing activities conducted by the participating companies in the exhibition affect the interest and repeat business deals of the visitors. The findings also show that the elements to induce the interest of the visitors such as the booth design and display of products where the participating companies may produce their unique image and the prior publicity to the visitors constitute the important elements of marketing. It has also been revealed that the visitors whose purpose of the visits are to purchase the products and to satisfy their interest in 'the events and contents of the events affect the interest and the repeat business deals of the visitors, among the interest and repeat business deals pursuant to the characteristics of the visitors. It has also been found that the visitors who have recognized the representative brands in the exhibitions affect the interest and the repeat business deals and the visitors who have visited the exhibition several times are more satisfied than the visitors who have visited the exhibition for the first time. The comparative evaluation of the degree of importance of the marketing activities of the participating companies before the visitors' visit to the exhibitions and the degree of satisfaction after their visit reveals degrees of satisfaction in the order of 'the booth staff's professional knowledge of the exhibits', 'foreign language proficiency and their techniques of negotiation and demonstration', 'designs of the exhibits (colors and packaging), 'prior publicity of the participating companies. Such being the case, the companies participating in any of the overseas should maximize the result of their participation in the exhibition by training their staff in the products and foreign languages and through the prior publicity. It has also been found out that "the atmosphere of the booth in the exhibition such as 'launching of new products', 'external appearances of the booth, layout of the interior facilities and the atmosphere and events of the participating companies affect the interest and repeat business deals of the visitors, among the factors for the satisfaction of the visitors. Therefore, it has been proven that the external factors such as the external appearances of the booth, display of the products, launching of new products and events producing the atmosphere of the booth of the participating companies among the marketing activities conducted by the participating companies, and the extent of the training of the booth staff and prior publicity are the major factors affecting the interest and repeat business deals of the visitors.

Recently, as the amount of academic literature has increased rapidly and complex researches have been actively conducted, researchers have difficulty in analyzing trends in previous research. In order to solve this problem, it is necessary to classify information in units of academic papers. However, in Korea, there is no academic database in which such information is provided. In this paper, we propose an automatic classification system that can classify domestic academic literature into multiple classes. To this end, first, academic documents in the technical science field described in Korean were collected and mapped according to class 600 of the DDC by using K-Means clustering technique to construct a learning set capable of multiple classification. As a result of the construction of the training set, 63,915 documents in the Korean technical science field were established except for the values in which metadata does not exist. Using this training set, we implemented and learned the automatic classification engine of academic documents based on deep learning. Experimental results obtained by hand-built experimental set-up showed 78.32% accuracy and 72.45% F1 performance for multiple classification.

For Korean phoneme recognition, Hidden Markov-Gaussian Mixture model(HMM-GMM) or hybrid models which combine artificial neural network with HMM have been mainly used. However, current approach has limitations in that such models require force-aligned corpus training data that is manually annotated by experts. Recently, researchers used neural network based phoneme recognition model which combines recurrent neural network(RNN)-based structure with connectionist temporal classification(CTC) algorithm to overcome the problem of obtaining manually annotated training data. Yet, in terms of implementation, these RNN-based models have another difficulty in that the amount of data gets larger as the structure gets more sophisticated. This problem of large data size is particularly problematic in the Korean language, which lacks refined corpora. In this study, we introduce CTC algorithm that does not require force-alignment to create a Korean phoneme recognition model. Specifically, the phoneme recognition model is based on convolutional neural network(CNN) which requires relatively small amount of data and can be trained faster when compared to RNN based models. We present the results from two different experiments and a resulting best performing phoneme recognition model which distinguishes 49 Korean phonemes. The best performing phoneme recognition model combines CNN with 3hop Bidirectional LSTM with the final Phoneme Error Rate(PER) at 3.26. The PER is a considerable improvement compared to existing Korean phoneme recognition models that report PER ranging from 10 to 12.

The essence of the definition of "tolerance" is analyzed. Motivational, knowledge and behavioral criteria for tolerance of future teachers are highlighted. Indicators of the motivational criterion are the formation of value orientations, motivational orientation, and the development of empathy. Originality and productivity of thoughts and judgments, tact of dialogue, pedagogical ethics and tact are confirmed as indicators of the knowledge criterion. The behavioral criterion includes social activity as a life position, emotional and volitional endurance, and self-control of one's own position. The formation of tolerance is influenced by a number of factors: the social environment, the information society, existing stereotypes and ideas in society, the system of education and relationships between people, and the system of values. The main factors that contribute to the education of tolerance in future teachers are highlighted. Analyzing the structure of tolerance, it is necessary to distinguish the following functions of tolerance: - motivational (determines the composition and strength of motivation for social activity and behavior, promotes the development of life experience, because it allows the individual to accept other points of view and vision of the solution; - informational (understanding the situation, the personality of another person); - regulatory (tolerance has a close connection with the strong - willed qualities of a person: endurance, selfcontrol, self-regulation, which were formed in the process of Education); - adaptive (allows the individual to develop in the process of joint activity a positive, emotional, stable attitude to the activity itself, which the individual carries out, to the object and subject of joint relations). The implementation of pedagogical functions in the information society: educational, organizational, predictive, informational, communicative, controlling, etc. provides grounds to consider pedagogical tolerance as an integrative personal quality of a representative of any profession in the field of "person-person". The positions that should become conditions for the formation of tolerance of the future teacher in the information society are listed.
