This study deals with the case of student-centered discrete mathematics class with cyber lab. First, we provided lecture notes and cyber labs we developed. In particular, discrete mathematics is a course that covers the principles of algorithms. The purpose of this study is to provide students with basic mathematics, aiming to actively participate in the learning process, to improve their abilities and to reach the ultimate goal of student success with confidence. Second, based on interactions, students were able to prepare for the lectures, review, question, answer, and discussion through an usual learning management system of the school. Third, all the students generated materials through one semester, which were reported, submitted, presented and evaluated. It was possible to improve the learning effectiveness through the discussions and implementation of using some easy open source programming language and codes. Our discrete math laboratory could be practiced without any special knowledge of coding. These lecture models allow students to develop critical thinking skills while describing and presenting their learning and problem-solving processes. We share our experience and our materials including lecture note and cyber lab as well as a possible model of student-centered mathematics class that does not give too much of work load for instructors. This study shares a model that demonstrates that any professor will be able to have an individualized, customized, and creative discrete education without spending much of extra time and assistant, unlike previous research.

The purpose of this paper is to examine the life and poetry of Hanchung. The reason for studying Hanchong is because there is no research on Hanchong until now. In Chapter 2, I looked at the life and poetry of Hanchung. One thing to pay attention to in the life of Hanchung is that Hanchung has excellent writing ability. When Hanchung went to the envoys in China, Hanchung was recognized for outstanding Chinese writing by Chinese officials. Another thing to pay attention to in the life of Hanchung is the upright character of Hanchung. Hanchung judged Nam-gon as a delicate person and did not live a life to cooperate with him. He vigorously rejected Namgon. Because of that, Hanchung was killed by Namgon. In Chapter 3, I examined the poems of Hanchung. The poem of Hanchung can be divided into three kinds. First, it reveals the love of the people. This comes from the heart of a child who pity the poor. Second, it is the mind to live while keeping the fidelity of life. This is reflected in the images of bamboo, pine and pine trees. Third, poetry criticizes reality. There are poems in Hanchung that reveal criticism of loneliness and reality. This is a political reality that is not right at the base. So, it can be said that it is a city that reveals the reality criticism after all.

This study surveyed the recognition on the Korean education for specific purposes targeting student-teachers majoring Korean language education in a Cyber University located in Seoul. 50 among 57 students taking the class participated in this survey. The participants were the students-teachers interested in Korean education for the mission purposes and took the class during the second term in 2020. At the end of the term they participated in this survey. 6 items were objective and 4 items were narrative. Among the narrative ones, one was excluded from analysis. The objective items were investigated by descriptive statics and the narrative items were analyzed with qualitative approach. As a result, most of the participants preferred the combined textbooks with others such as the ones for general and mission purposes rather than the bibles only. They had positive opinions on using the bibles, but proposed that the bibles themselves are not the best choice for improving communicative competence and the text combination is the better choice because of the difficulty of the bibles, the lack of teachers' competence, and the learners' needs. However, while taking this class, they became to be aware of the possibilities of the bibles as textbooks, to possess the concern about the mission areas, to consider the possibilities of application and the educational methods in it, and to reflect the ways for self development. This study suggested several points as follows: the development of diverse textbooks according to situations and learners, two directions of teacher education and the cooperative works, and the necessities of the related departments and classes with mission purposes.

This paper intends to say that children's worship as a liturgy for children living in modern society is an important place to support children's personal development and experience of coziness necessary for their personal development. To this end, this thesis first regards modern society as an unstable society, analyzes fluid society and individualism as the causes, and deals with changes in educational style accordingly. In a fluid society, children are not provided with a solid form and lasting environment that supports personality development, and the education style changed under the influence of individualism and pluralism requires a heavy task of determining the direction of one's life and constantly making choices and decisions. Therefore, children need rules and forms that help them live together, and they need a space that can give them comfort that helps them develop their personality. As an argument for this, second, this paper deals with the concept and function of the liturgy in order to understand the worship of children as the liturgy. The third deals with the elements necessary for the development of children's personality that can be experienced in children's worship. First, it deals with the meaning of religious, aesthetic, and communal driving forces that children can experience in children's worship, focusing on Eberhard's research. In addition, it deals with the meaning of language and expression methods provided in children's worship, and finally, it says that children's worship can be a space where you can experience stability and coziness. Through this, it is emphasized that children's worship can play an important role in supporting the personal development of children living in modern times.

Presenting symbolic concepts consistent with the culture of the host country and international trends at international events will win the favor of the world and raise the image of the host country. The international event mascot symbolically represents the host country's unique culture, and is a good means to enhance the sense of belonging and pride of its members and to display the image of the host country in an outwardly. This study discussed the symbolic elements of the host country characteristics reflected in FIFA's World Cup event mascot. A total of 14 mascots of World Cup events were held from 1966 to 2018, and their materials can be divided into animals, plants, people and creations. The mascot was applied with the characteristic elements of regional specialties, the flag of the host country, symbolic attire, language of the hosting area, social issues and the mascot's dress, posture, props and expression characters of soccer events were used as symbolic elements. First of all, the implications of the research were that mascots were more strongly expressing the "football" signifying element, the theme of events, rather than regional characteristics. Second, the use of 'national flag' was highlighted among the elements of expressing regional characteristics. Third, 'animal' was preferred for mascot material. Fourth, mascots have become integrated with 'cultural perfumes' and play an extended role in raising social awareness. Implications derived from the classification of characteristics and symbol representation elements raised in this study will be used as a basis for the planning of international event mascots.

The purpose of this study is to propose a Busan tourism industry in which the 2016 OECD Tourism policy and ICT convergence platform are applied. OECD proposed 3 policies to promote the tourism industry: First, to maintain the competitiveness of the tourism industry as well as improve its efficiency and sustainability, second, to establish a seamless traffic system, and third, to build a response to the sharing economy. Centering on the OECD's three policies, we propose the developmental possibilities of tourism in Busan. At the same time, we suggest the necessity to build an ICT convergence platform that will help foster the industry. In building an ICT convergence platform, we especially focus on the necessity of: 1. Sharing and creating experience-based interactive contents on the software side, and 2. Developing high quality user experience (UX) and providing a data analysis-based customized service on the hardware side. In addition, we insist on the establishment of the Tourism Promotion Agency for the continuous performance and management of Busan tourism industry. The study ultimately suggests that the construction of ICT convergence platform based on OECD tourism policy can result in the expected outcomes of high effects with low cost for both consumers and suppliers related to the tourism industry.

The importance of barrier free is being highlighted worldwide. This study attempted to identify barrier-free research trends using text mining. Through this, it was intended to help with research and policies to create a barrier free environment. The analysis data is 227 papers published in domestic academic journals from 1996 when barrier free research began to 2022. The researcher converted the title, keywords, and abstract of an academic thesis into text, and then analyzed the pattern of the thesis and the meaning of the data. The summary of the research results is as follows. First, barrier-free research began to increase after 2009, with an annual average of 17.1 papers being published. This is related to the implementation guidelines for the barrier-free certification system that took effect on July 15, 2008. Second, results of barrier-free text mining i) As a result of word frequency analysis of top keywords, important keywords such as barrier free, disabled, design, universal design, access, elderly, certification, improvement, evaluation, and space, facility, and environment were searched. ii) As a result of TD-IDF analysis, the main keywords were universal design, design, certification, house, access, elderly, installation, disabled, park, evaluation, architecture, and space. iii) As a result of N-Ggam analysis, barrier free+certification, barrier free+design, barrier free+barrier free, elderly+disabled, disabled+elderly, disabled+convenience facilities, the disabled+the elderly, society+the elderly, convenience facilities+installation, certification+evaluation index, physical+environment, life+quality, etc. appeared in a related language. Third, as a result of the CONCOR analysis, cluster 1 was barrier-free issues and challenges, cluster 2 was universal design and space utilization, cluster 3 was Improving Accessibility for the Disabled, and cluster 4 was barrier free certification and evaluation. Based on the analysis results, this study presented policy implications for vitalizing barrier-free research and establishing a desirable barrier free environment.

The purpose of this study is to provide the case study of expression education using story-telling about their cultures from which they came to the women who get interracial married and study korean cultures with the pride of their homeland. This research is also for the diverse members of korean society to deeply understand interracial married women, get higher understanding cultural diversities. And it is expected that these women could learn and study more korean cultures, too. In this study, process-based instruction method is used in the first step and second step such as brainstorming, questioning, discussing, investigating, teacher's asking in order to create some ideas about their home countries. Suggesting an example answer by teacher and free-writing are also involved. As the core of the process-based writing activity, the second step is focused on revising and correcting. Through reviewing their own writing task, feedback from teacher, interviewing from the difficulty of writing after this activity to cultural and linguistic backgrounds, they could appreciate their errors or mistakes in writing are natural and this affects their learning abilities positively. In third step which is focused on speaking activities, teacher provides feedback to learners after checking their common errors or habits in speaking. Meanwhile, by evaluating the role of the appraiser, It is helpful for the learners to have self-esteem of their own. When interviewing after fourth step's activities, the teacher compliments each learner's improvement while pointing out some errors. Afterward, We can see they show more positiveness to learn and understand korean cultures and set their identities. And they indicate interests and concerns each other's cultures by story-telling. It means they identify the popularity and interaction which the story-telling contains. Also, they confirm the participation in story-telling by expressing their willingness to revise their stories. After the activities in fifth step, there have been relatively positive changes in establishing identity and cultivating a sense of pride of learner's homeland cultures. Furthermore, we could find the strong will to be a story-teller about their homeland cultures. On this research, the effectiveness of expression education case study using story-telling about local cultures of interracial married women's homeland has been examined centrally focused on popularity, interaction, and participation. Afterward, interracial married women could not only cultivate the understanding about korean cultures but also establish their identity, improve their korean language skills through this education case study. Finally, the studies of the education programs to train interracial married women as story-tellers for their homeland local cultures are expected.

Ethnography is concerned about specifically-based behavior and belief and the learned pattern of language and aims to describe and interpret them. Therefore, it is a classical form of qualitative research that was developed by anthropologists who spent for long time in conducting fieldworks within the cultural group. The results of analyzing ethnographic research methods of doctoral dissertations in Korea are as follows. First, the number of research participants in data collection methods was 1-10(32 dissertations, 44.4%), 11-20(18, 25%), 21-30(13, 18.1%), 31-40(2, 2.7%), and others(7, 9.8%). Second, data collection methods were in-depth interview(71, 98.6%), participant observation(70, 97.2%), document data(38, 52.7%), engineering device(12, 16.6%), and others(8, 11.1%). Data collection periods were 3-5 months(7 dissertation, 9.8%), 6-8 months(15, 20.8%), 9-11 months(14, 19.6%), 12-14 months(13, 18.1%), more than 15 months(17, 23.6%), and unpresented(4, 5.4%). Third, trustworthiness criteria were triangulation(46 dissertation, 63.9%), research participants' evaluation of study results 44(61.1%), peer researchers' advice and indication(33, 45.8%), follow-up(25, 34.7%), use of reference(20, 27.8%), reflexive subjectivity(17, 23.6%), intensive observation for a sufficient period(10, 13.9%), in-depth description(7, 9.8%), and others(7, 9.8%).

Omission of noun phrases for obligatory cases is a common phenomenon in sentences of Korean and Japanese, which is not observed in English. When an argument of a predicate can be filled with a noun phrase co-referential with the title, the argument is more easily omitted in Encyclopedia texts. The omitted noun phrase is called a zero anaphor or zero pronoun. Encyclopedias like Wikipedia are major source for information extraction by intelligent application systems such as information retrieval and question answering systems. However, omission of noun phrases makes the quality of information extraction poor. This paper deals with the problem of developing a system that can restore omitted noun phrases in encyclopedia documents. The problem that our system deals with is almost similar to zero anaphora resolution which is one of the important problems in natural language processing. A noun phrase existing in the text that can be used for restoration is called an antecedent. An antecedent must be co-referential with the zero anaphor. While the candidates for the antecedent are only noun phrases in the same text in case of zero anaphora resolution, the title is also a candidate in our problem. In our system, the first stage is in charge of detecting the zero anaphor. In the second stage, antecedent search is carried out by considering the candidates. If antecedent search fails, an attempt made, in the third stage, to use the title as the antecedent. The main characteristic of our system is to make use of a structural SVM for finding the antecedent. The noun phrases in the text that appear before the position of zero anaphor comprise the search space. The main technique used in the methods proposed in previous research works is to perform binary classification for all the noun phrases in the search space. The noun phrase classified to be an antecedent with highest confidence is selected as the antecedent. However, we propose in this paper that antecedent search is viewed as the problem of assigning the antecedent indicator labels to a sequence of noun phrases. In other words, sequence labeling is employed in antecedent search in the text. We are the first to suggest this idea. To perform sequence labeling, we suggest to use a structural SVM which receives a sequence of noun phrases as input and returns the sequence of labels as output. An output label takes one of two values: one indicating that the corresponding noun phrase is the antecedent and the other indicating that it is not. The structural SVM we used is based on the modified Pegasos algorithm which exploits a subgradient descent methodology used for optimization problems. To train and test our system we selected a set of Wikipedia texts and constructed the annotated corpus in which gold-standard answers are provided such as zero anaphors and their possible antecedents. Training examples are prepared using the annotated corpus and used to train the SVMs and test the system. For zero anaphor detection, sentences are parsed by a syntactic analyzer and subject or object cases omitted are identified. Thus performance of our system is dependent on that of the syntactic analyzer, which is a limitation of our system. When an antecedent is not found in the text, our system tries to use the title to restore the zero anaphor. This is based on binary classification using the regular SVM. The experiment showed that our system's performance is F1 = 68.58%. This means that state-of-the-art system can be developed with our technique. It is expected that future work that enables the system to utilize semantic information can lead to a significant performance improvement.
