This study is aimed at verifying the effects of an ETC(Expressive Therapies Continuum)-based group art therapy program on reducing parental anxiety in first-grade elementary school students' mothers. An ETC program was composed based on the therapeutic factors of the ETC components. Seven mothers of first-grade students located in city A of Gyeonggi-do were selected as the subjects of the study. These mothers underwent 11 sessions of ETC-based group art therapy from April 18 to May 24, 2019, 1 to 2 times a week for 70 to 90 minutes. In order to verify the effectiveness of this research program, scores from pre- and post-parental anxiety scales were analyzed using SPSS 24.0 program. Results demonstrated that first, mothers' parental anxiety was significantly reduced after the ETC program participation. Second, changes in ETC component use throughout the program positively influenced reductions in parental anxiety. In conclusion, each participant experienced the opportunity to self-explore and self-understand at all levels of ETC with their preferred art medium, thereby lowering parenting anxiety. It is meaningful that through the ETC-based art therapy program, the client can be self-aware of his or her problem, and the client can decide the direction that is beneficial to them through voluntary media selection. In addition, it is meaningful that the ETC group art therapy is able to perform activities tailored to each individual.

Recently, there is becoming larger interest in the public practice centers equipped with advanced manufacturing equipment of industries that is difficult to have in all vocational high schools for strengthening practical education and technical education tailored to the Fourth Industrial Revolution in vocational high schools. In this study, using spatial optimization approaches, we explored the optimal location sets of the public practice centers of vocational high schools in Seoul for an illustration. For the proposed optimial location methods, P-median Problem (PMP) and Maximal Coverage Location (MCLP) were used because, when the public practice centers located in priority of large vocational high schools based on the number of students, it showed that the result is not minimizing the travel distance and maximizing the demand of the vocational high school students. This study found that the PMP can find the optimal location sets that minimize the travel distance of whole students. In addition, all students can be captured through locating five public practice centers by MCLP. It should be noted that the optimal locations of this study are limited in Seoul. However, the frame of this methodology applied in this study can be utilized to locate the public practice centers in other regions based on the spatial decision making.

Curriculum content interest has been studied in terms of teachers rather than students in ways that help revise curriculum and develop textbooks. In this study, 227 first-year high school students were interested in what they learned in middle school and what they learned in high school, focusing on meaningful assumptions and contents for middle school and high school students. We analyze this difference in interest by gender and achievement level. According to the research results, first-year high school students, who are in the middle and high school transition period, have relatively high interest in themselves, such as youth development, compared to family needs or interest in family life. There were no gender differences, but there were differences in content interest depending on the level of achievement. This means that the content interest should be interpreted by considering various variables such as the development of learners, the situation of learners in the school-level transition period, and the entrance examination of universities. The results of this study will provide implications for future curriculum revisions, textbook development, and curriculum considerations, and will need to be carefully analyzed and utilized based on a learner-centered perspective.

The high-tech industry, a leader in the national economy, has a larger investment cost compared to general buildings, a shorter construction period, and requires continuous investment. Therefore, accurate construction cost prediction and quick decision-making are important factors for efficient cost and process management. Overseas, the construction information classification system has been standardized since 1980 and has been continuously developed, improving construction productivity by systematically collecting and utilizing project life cycle information. At domestic construction sites, attempts have been made to standardize the classification system of construction information, but it is difficult to achieve continuous standardization and systematization due to the absence of a standardization body and differences in cost and process management methods for each construction company. Particular, in the case of the high-tech industry, the standardization and systematization level of the construction information classification system for high-tech facility construction is very low due to problems such as large scale, numerous types of work, complex construction and security. Therefore, the purpose of this study is to construct a construction information classification system suitable for high-tech facility construction through collection, classification, and analysis of related project data constructed in Korea. Based on the WBS (Work Breakdown Structure) and CBS (Cost Breakdown Structure) classified and analyzed through this study, a code system through hierarchical classification was proposed, and the cost model of buildings by linking WBS and CBS was three-dimensionalized and the utilized method was presented. Through this, an information classification system based on inter-relationships can be developed beyond the one-way tree structure, which is a general construction information classification system, and effects such as shortening of construction period and cost reduction will be maximized.

The purpose of this study is to provide basic data for the development of the anger provoking situation scale using the mixed research method. For this purpose, three research methods were used: content analysis of domestic and international anger-inducing situation scale, NAS-PI factor and reliability analysis of youth anger-provoking scale, and FGI with youth expert. In the results of NAS-PI, there were four categories of 'unrespectful treatment', 'unfairness', 'annoying traits of others', and 'irritation' except 'frustration' among five categories. The results of the FGI consisted of seven categories: 'rejection', 'physical and verbal violence', 'ignorance', 'frustration', 'control and restraint', 'rumination', and 'interpersonal relationship'. As a result of integrating these contents, it is finally possible to reconstruction in to seven categories such as 'unfairness', 'injustice', 'ignorance', 'control and restraint', 'ignorance', 'frustration' 'interpersonal relationship'. The meaning of this study is to provide the basic data for the development of the anger provoking situation scale for domestic adolescents by integrating the contents analysis and quantitative and qualitative researches of domestic and international anger provoking situation scale. The results of this study are as follows. First, it is necessary to study the anger provoking situations reflecting sociocultural context, and to develop the reliability and validity of the anger provoking situation scale.

In North Korea, where there was little external activity, the number of overseas academic paper publications has recently increased. This study aims to quantitatively analyze North Korean papers published abroad to identify changes in North Korea's research and development trends, and to explore the possibility of developing them through joint research with domestic researchers in the future. To this end, since 1986, frequency analysis and network analysis have been conducted on papers published overseas including North Korean researchers. The analysis was conducted on authors, research institutes, countries, and research fields, and changes were analyzed before and after Kim Jong-un took office. According to the results of the analysis, as the number of foreign papers published rapidly increased during the eight years after Kim Jong-un took office, the composition of the top researchers, research institutes, and researchers with high influence in joint research also changed a lot. After Kim Jong-un came to power, the proportion of North Korean researchers and research institutes increased relatively, and a network component was formed between researchers with high influence on joint research, so it was observed that they focused on specific research topics. It was found that the major foreign collaborators or research institutes of North Korean researchers were from China.

The planning of traditional urban has to face great challenges under the influence of the uncertainty and mobility of contemporary cities. While for this kind of challenge, it has brought the chance to develop Landscape Urbanism quickly. As an important practice place for Landscape Urbanism, open space provides a platform for many landscape designers to display. The purpose of this research is to explore the expression of the core content of Landscape Urbanism in open space, and propose the design tendency of open space in Korea. According to the constitution elements of urban open space and the core concept of Landscape Urbanism, this thesis establishes the analysis framework, which carries out the case empirical analysis for the open space of New York. Through case analysis, we can see that there are five major characteristics of Landscape Urbanism. That is, the integration or imitation of natural terrain, green infrastructure construction, emphasizing ecological resilience, adaptability to unplanned events, and analyzing the site from multiple scales. In this research, the design proposal proposed on the basis of Landscape Urbanism is able to provide enlightenment for the urban open space design of Korea in the future.

We investigate the performance of deep learning-based Korean language models on a task of predicting the score range of Korean essays written by foreign students. We construct a data set containing a total of 304 essays, which include essays discussing the criteria for choosing a job ('job'), conditions of a happy life ('happ'), relationship between money and happiness ('econ'), and definition of success ('succ'). These essays were labeled according to four letter grades (A, B, C, and D), and a total of eleven essay score range prediction experiments were conducted (i.e., five for predicting the score range of 'job' essays, five for predicting the score range of 'happiness' essays, and one for predicting the score range of mixed topic essays). Three deep learning-based Korean language models, KoBERT, KcBERT, and KR-BERT, were fine-tuned using various training data. Moreover, two traditional probabilistic machine learning classifiers, naive Bayes and logistic regression, were also evaluated. Experiment results show that deep learning-based Korean language models performed better than the two traditional classifiers, with KR-BERT performing the best with 55.83% overall average prediction accuracy. A close second was KcBERT (55.77%) followed by KoBERT (54.91%). The performances of naive Bayes and logistic regression classifiers were 52.52% and 50.28% respectively. Due to the scarcity of training data and the imbalance in class distribution, the overall prediction performance was not high for all classifiers. Moreover, the classifiers' vocabulary did not explicitly capture the error features that were helpful in correctly grading the Korean essay. By overcoming these two limitations, we expect the score range prediction performance to improve.

Due to the convergence of broadcasting and telecommunication and the evolution into the media industry, viewers are adapting to the reception of content through various platforms and personal media. Accordingly, public broadcasting is seeking to change into public media that redefines public responsibility and establishes a role for a sustainable society. In particular, proving its value in the form of differentiated public services in an environment where public content is also provided by commercial services is necessary for members of society to prove the legitimacy of financial resources and services. In this paper, as the digital broadcasting era in the 2010s and the media industry was reorganized in 2020, changes in public services corresponding to the public responsibilities required of public broadcasters were analyzed through global public broadcasting cases. In particular, since the technical preparation of broadcasters and viewers is essential in the media environment, the technical direction of public services was mainly analyzed. The derived direction is a common direction applicable to all public broadcasters, including Korea. It is expected that the public responsibility and direction of technological development suggested in this paper will clarify the role of public media and help become differentiated services that contribute to life.
