  • There is a Korean proverb that learns old things and learns new things from it. This study analyzes the change of the policy governance system in the field of information and communication since 2008 and outlines the future directions. The launch of the Korea Communications Commission (KCC), which combines the Ministry of Information and Communication and the Korea Broadcasting Commission in 2008, and the separation of the Korea Communications Commission and Ministry of Science, ICT and Future Planning in 2013, were systematic responses to the policy environment. Recent changes in the ICT environment, such as the advent of the fourth industrial revolution and the intelligence information society, call for an organizational timely response. In the future, it will be very important to set the scope of ICT policy, the establishment of a dedicated organization, the strengthening of the regulatory system, and the role of the government and the market.

  • The purpose of this study is to explore the direction of multicultural mentoring class activities in order to promote the professional growth and critical reflection of student mentors who are undergraduate students from a variety of major. For this purpose, the contents and phenomena of the multicultural mentoring of the mentor - mentee were reported as activity texts, and then seven directions of textuality were applied to explore the direction of multicultural mentoring class activities. As a result, coherence refers to the relationship between the mentor and the mentee for continuing the activities of multicultural mentoring, and cohesiveness refers to the relationship between the mentor and the mentee. It was called the achievement of identity. Intention means that the mentor has an intention or goal for the class before the mentoring activity, and tolerance means that the text produced by the mentor in the multicultural mentoring process is accepted by the mentee. Intentional means that the mentor has intention or goal for the class before the mentoring class activity, and tolerance means having the text as the class activity text when the mentor's text is accepted by the multicultural mentoring class activity process. In the case of informativeness, the information produced by the mentor is less informative when the mentee is predictable and less informative when the predictor is low. In the case of contextuality, contextuality of class activities can be changed according to the physical text situation and the mentee situation in class activity. In case of multicultural mentoring class activity, except for case where mentor creates new class activity text, it is related to the production of class activity texts through mentor learning experiences, peer friends' advice, and education.

  • The inflow of Labor Migrants has been grown up to 600,000 people until now with the adoption of Employment Permit System (EPS) in 2004 until now. However the institutional support lack to ensure their rights and improve their conditions. This is because of their consideration ad temporary labors in South Korean society and labor forces rather than the objects of integration. As a result, the legal status and rights of migrant workers are criticized for their utilization rather than human rights, and human rights protection is insufficient. To this context, this paper analyzed the 19th presidential election pledge of the four political parties (Democratic Party, the Liberty Korea Party, Bareun Party and Justice Party) the majority of the Korean National Assembly, and predicted how the policies of migrant workers would evolve. The study found that there were two political parties that did not mention policies for migrant workers, and the remaining two parties also maintained their current policies. This is probably the biggest reason to recognize migrant workers as temporary residents. However, they should also be aware of the fact, that migrant workers are the members of the Korean society and are the owners of human rights that should be guaranteed, and should consider the policy directions to live with them.

  • This article was prepared for the purpose of reviewing maintenance plans and strategies for designating the celadon kiln site in Banam-ri, Gochang, a monument designated by the city and province as a historical site. Prior to the discussion, the high academic potential of this site, which is attracting attention as a main point of early celadon main point, was explained, and expectations for the future designation of the monument were reviewed. Next, the current status of preservation and maintenance plans of the celadon kiln site in Banam-ri, Gochang were examined. In particular, the current preservation situation was reviewed through an on-site survey on how the ruins, which have not been designated as a monument, should be maintained for historical designation in the future. Above all, it was argued that it was necessary to conduct excavation and literature surveys to clarify the characteristics of the ruins, investigate the surrounding areas, improve information facilities for visitors, and carry out promotion in connection with them. Finally, the definition of historical sites and the status of historical designation of ceramic kilns, along with the strategies necessary for designation, were presented. In particular, the examples of the existing historical designated celadon kiln site in Dotong-ri, Jinan, and Buncheong Kiln Site in Undae-ri, Goheung were reviewed, and three types of excavation surveys, literature surveys, and academic conferences were presented as the target directions for historical designation. The result of the excavation survey is the basis for suggesting that it has cultural property values with completeness, authenticity, and identity. The literature survey is the basis for supplementing the historical and cultural character of the remains that have not been revealed by excavation. The academic conference explained that it is an opportunity to understand the nature and value of cultural assets, such as the location of cultural assets, the status of relics, and events related to relics.

  • Grit is a person's passion and perseverance that drive them to achieve long-term and meaningful goals. The purpose of this study was to identify practical resources that can affect single parents' grit. Using the fourth-year panel data from the Korean Children and Youth Panel Survey 2018 (KCYPS 2018), descriptive statistics were produced and a correlation analysis was conducted for 284 single parents. Hierarchical regression analysis was also performed to explore the demographic factors, personal resources(psychological, lifestyle/health), and family resources(family relationships/child, economic) that affect single parents' grit. First, the correlation analysis revealed that single parents' grit had a significant correlation with age, education status, life satisfaction, happiness, self-esteem, smartphone dependency, physical activity time, frequency of breakfast consumption, household size, parent's satisfaction with child's school achievement and school adjustment, subjective family economic status, and private education expenses. Second, the hierarchical regression analysis revealed that education status, self-esteem, employment status, smartphone dependency, physical activity time, household size, parent's satisfaction with child's school achievement, and subjective family economic status were significant factors affecting single parents' grit. Based on the research results, this study suggests directions for programs and policies to provide a stable environment for single-parent families to raise their children.

  • In this study, we comprehensively analyze the generalization performance of various deep learning-based active sonar target classifiers when applied to small and imbalanced active sonar datasets. To generate the active sonar datasets, we use data from two different oceanic experiments conducted at different times and ocean. Each sample in the active sonar datasets is a time-frequency domain image, which is extracted from audio signal of contact after the detection process. For the comprehensive analysis, we utilize 22 Convolutional Neural Networks (CNN) models. Two datasets are used as train/validation datasets and test datasets, alternatively. To calculate the variance in the output of the target classifiers, the train/validation/test datasets are repeated 10 times. Hyperparameters for training are optimized using Bayesian optimization. The results demonstrate that shallow CNN models show superior robustness and generalization performance compared to most of deep CNN models. The results from this paper can serve as a valuable reference for future research directions in deep learning-based active sonar target classification.

  • In the purpose of this study, the college textbooks of self-narrative writing and examples of classroom practice are analyzed to find a way to educate it. The self- narrative writing subject with a learning of recognization, expression, and communication with oneself, emphasizes the necessity when they become college students through entrance exam-oriented education. The research methods are as follows. Firstly, three university textbooks which include a section on self-narrative writing were compared and analyzed. The analysis highlights the needs for a textbook covering self-narrative writing more extensively and comprehensively as what is offered by the existing textbooks is limited in facilitating students to fully develop the ability of self-reflection, which should be dealt as a long-term goal. Secondly, the current discussion on self-narrative writing and examples of real classroom practice were analyzed. It shows that a step-by-step approach is required to encourage the practice of deep self-reflection to be incorporated into writing. In addition, during the writing process, various correction and feedback activities should be carried out on a macro level and gradually while the communication and feedback should take place not only between a teacher and students, but also among students. As a result, it is expected that this study will help establish a teaching model of self-narrative writing by seeking complementary points and educational directions for self-narrative writing.

  • This paper intends to enhance the reliability and performance of domestic elastomeric bearings through the proposal of directions for the improvement of their stiffness regard to the Korean industrial standard KS F 4420 relative to the evaluation of design/fabrication/quality. Therefore, comparative analysis of the compressive elastic modulus, stiffness measurement method and performance evaluation method of KS F 4420 with those of Eurocode, Japanese bearing manual, and ISO code was performed, and measurement tests on the compressive stiffness and shear stiffness of common elastomeric bearings produced in Korea were conducted. The experimental results reveal that differences of about 20% and 13% occurred respectively for the compressive stiffness and shear stiffness according to the definition adopted for the stiffness. The measured values for the stiffness of the domestic elastomeric bearings were also verified to exhibit large deviation from the formula proposed by KS F 4420. Elastomeric bearings that does not have appropriate compressive stiffness required at the design can result in uneven deflection at supports of bridges and excessive stress in girders. Accordingly, the establishment of compressive elastic modulus formula and performance evaluation criteria fitted to the domestic circumstances through the execution of performance evaluation of bearings presenting diversified shapes and shape factors appears to be necessary for the domestic bearings to meet the performance required in design.

  • The aim of this study is to investigate a correlation between fundamental data on aerodynamic characteristics of bridge girder cross-sections, such as aerodynamic force coefficients and flutter derivatives, and their aerodynamic behaviour. The section model tests were carried out in three stages. In the first stage, seven deck configurations were studied, namely; Six 2-edge girders and one box girder. In this stage, changes in aerodynamic force coefficients due to geometrical shape of girders, incidence angle of flow, wind directions and turbulence intensities were studied by static section model tests. In the second stage, the dynamic section model tests were carried out to investigate the relativity of static coefficients to dynamic responses. And finally, the two-dimensional (lift-torsion) aerodynamic derivatives of three bridge deck configurations were investigated by dynamic section model tests. The aerodynamic derivatives can be best described as a representation of the aerodynamic damping and the aerodynamic stiffness provided by the wind for a given deck geometry. The method employed here to extract these unsteady aerodynamic properties is known as the initial displacement technique. It involves the measurement of the decay in amplitude with time of an initial displacement of the deck in heave and torsion, for various wind speeds, in smooth flow. It is suggested that the proposed aerodynamic force coefficients and flutter derivatives of bridge girder sections will be potentially useful for the aeroelastic analysis and buffeting analysis.
