Simultaneous translation is online decoding to translates with only subsentence. The goal of simultaneous translation research is to improve translation performance against delay. For this reason, most studies find trade-off performance between delays. We studied the experiments of the fixed policy-based simultaneous translation in Korean. Our experiments suggest that Korean tokenization causes many fragments, resulting in delay compared to other languages. We suggest follow-up studies such as n-gram tokenization to solve the problems.

Neural machine translation using deep neural network has emerged as a mainstream research, and an abundance of investment and studies on model structure and parallel language pair have been actively undertaken for the best performance. However, most recent neural machine translation studies pass along decoding strategy to future work, and have insufficient a variety of experiments and specific analysis on it for generating language to maximize quality in the decoding process. In machine translation, decoding strategies optimize navigation paths in the process of generating translation sentences and performance improvement is possible without model modifications or data expansion. This paper compares and analyzes the significant effects of the decoding strategy from classical greedy decoding to the latest Dynamic Beam Allocation (DBA) in neural machine translation using a sequence to sequence model.

This study is to develop a named entity recognition model specialized in criminal investigation domains using deep learning techniques. Through this study, we propose a system that can contribute to analysis of crime for prevention and investigation using data analysis techniques in the future by automatically extracting and categorizing crime-related information from text-based data such as criminal judgments and investigation documents. For this study, the criminal investigation domain text was collected and the required entity name was newly defined from the perspective of criminal analysis. In addition, the proposed model applying KoELECTRA, a pre-trained language model that has recently shown high performance in natural language processing, shows performance of micro average(referred to as micro avg) F1-score 98% and macro average(referred to as macro avg) F1-score 95% in 9 main categories of crime domain NER experiment data, and micro avg F1-score 98% and macro avg F1-score 62% in 56 sub categories. The proposed model is analyzed from the perspective of future improvement and utilization.

Based on the importance of dialect research, preservation, and communication, this paper conducted a study on machine translation of Korean dialects for dialect users who may be marginalized. For the dialect data used, AIHUB dialect data distributed based on the highest administrative district was used. We propose a many-to-one dialect machine translation that promotes the efficiency of model distribution and modeling research to improve the performance of the dialect machine translation by applying Copy mechanism. This paper evaluates the performance of the one-to-one model and the many-to-one model as a BLEU score, and analyzes the performance of the many-to-one model in the Korean dialect from a linguistic perspective. The performance improvement of the one-to-one machine translation by applying the methodology proposed in this paper and the significant high performance of the many-to-one machine translation were derived.

The purpose of this study is to find out the competence of porspective speech and language pathologist according to Clinical practicums and to use it as basic data in guiding porspective speech and language pathologist. The porspective speech and language pathologist competence consisted of tasks, knowledge, skills, and language areas, and a total of 36 questionnaires were organized by dividing the language areas into sub-areas of smantics, morphology and pragmatics. A total of 105 questionnaires were collected from students with experience in Clinical practicums. A t-test, Pearson correlation analysis, and simple regression analysis were conducted to analyze the competence of porspective speech and language pathologist according to whether or not they practiced. The results of this study are as follows. First, there were significant differences between groups in all areas of knowledge, tasks, skills, and language in the competence area. Second, there was a very strong correlation between competence and language sub-areas. Third, it was found that it had a significant explanatory power in the sub-area of competence and language areas, and had a positive effect on the competence of porspective speech and language pathologist. This study is meaningful in that it should be based on theoretical knowledge of language elements to enhance the competence of porspective speech and language pathologist, and it can be confirmed that theory affects the competence of porspective speech and language pathologist. It is expected to be meaningfully used as a basis for efficient teaching methods based on the improvement of the capabilities of porspective speech and language pathologist, training training professional language rehabilitators, and theory, and theory.

The purpose of this study was to analyze the cases of verbal interactions occurring during the mathematics lessons taught in middle school special classes in order to examine the elements and types of verbal interactions that occur between the teachers and students. Data were collected and analyzed for the sessions on geometric units that formed part of the mathematics lessons routinely implemented in the special classes. The analysis showed that the teachers initiated 237 (84.1%) of the 291 instances of verbal linguistic interactions. A total of 240 teachers' questions were analyzed, and questions in the area of knowledge occurred the most frequently, at 160 times (66.7%). A total of 617 student responses were analyzed, and short answers occurred the most frequently, at 367 times (59.5%). Teacher feedback occurred 581 times in total, and correct/incorrect (simple) feedback occurred the most frequently, at 234 times (40.3%). A total of 237 verbal interactions were observed between the teachers and children, and the I (RF) type (one teacher question, one student response, and one instance of teacher feedback) occurred most frequently, at 83 times (35.0%).

This research examines mutual culture education in accordance with Germany's immigrant social integration policy by analyzing the National European School in Berlin. In this regard, the curricula of Joan-Miró elementary school and Finow elementary school are analyzed. Germany maintains a multicultural policy which enables immigrants to maintain their native language and identity and simultaneously integrate them into the German society. In short, maintenance of immigrants' mother tongue and immigrant students' acquisition of the German language is the core of Germany's social integration policy. The National European School in Berlin is a public school established for the sake of an educational environment in which students can not only build up language capacity, but also create a culturally mutual environment for multicultural students. The school's educational objective is mutual culture education which can integrate and maintain the cultural identity and language of multicultural students. Joan-Miró elementary school encourages mutual cultural ability and bilingual ability while preparing students for the future intelligent society, leading their independent life and self-initiated learning. Finow elementary school encourages mutual culture ability, language capacity and directional capability apart from the basic capacities that can reinforce students to become citizens in demand of the future intellectual society. Korean foreign language education needs to be practically diversified as in the case of the Germany's National European school. Also, improvement of educational environment such as students' bilingual ability, students' ability development regarding their individual characteristics, and the capability of mutual culture understanding are issues that should be urgently treated.

This study aims to investigate the mediating effects of commitment to learning on the relationship between instructor communication and reselection of the same instructor among college students in lifelong education. For this purpose, the investigator conducted a survey with college students in lifelong education attending a two or three year college or a university in Daegu Metropolitan City and Gyeongsangbuk Province and analyzed a final total of 498 questionnaires with the SPSS 22.0 and AMOS 22.0 statistical programs. The findings were as follows: instructors' verbal and non-verbal communication had total significant effects on the path of reselection of the same instructor by college students in lifelong education, but it had no direct significant effects on reselection of the same instructor. Instructors' verbal and non-verbal communication had indirect effects on reselection of the same instructor by college students in lifelong education via commitment to learning. These findings imply that if instructors make use of their verbal and non-verbal communication in lessons for college students in lifelong education according to their characteristics, it will be able to increase their commitment to learning as well as satisfaction with lessons.
