Improvements in people's quality of life, diversification of leisure activities, and changes in population structure have led to an increase in the demand for tourism and an expansion of the diversification of tourism activities. In particular, for coastal cities where land and marine tourism elements coexist, various factors influence their tourism demands. Tourism requires the construction of infrastructure and content development according to the demand at the tourist destination. This study aims to improve the prediction accuracy and explore influencing factors through time series analysis of tourism scale using agent-based data. Basic local governments in the Busan area were examined, and the data used were the number of tourists and the amount of tourism consumption on a monthly basis. The univariate time series analysis, which is a deterministic model, was used along with the SARIMAX analysis to identify the influencing factor. The tourism consumption propensity, focusing on the consumption amount according to business types and the amount of mentions on SNS, was set as the influencing factor. The difference in accuracy (RMSE standard) between the time series models that did and did not consider COVID-19 was found to be very wide, ranging from 1.8 times to 32.7 times by region. Additionally, considering the influencing factor, the tourism consumption business type and SNS trends were found to significantly impact the number of tourists and the amount of tourism consumption. Therefore, to predict future demand, external influences as well as the tourists' consumption tendencies and interests in terms of local tourism must be considered. This study aimed to predict future tourism demand in a coastal city such as Busan and identify factors affecting tourism scale, thereby contributing to policy decision-making to prepare tourism demand in consideration of government tourism policies and tourism trends.

Even though styrofoam buoys represent a large portion of beached marine debris in Korea, efficient government actions have been lacking to address them. Three participatory workshops were organized from 2010 to 2012 to develop policy measures to manage styrofoam buoy marine debris. The first workshop held in 2010 was organized in order for workshop participants to understand and share the styrofoam debris issue. Participating stakeholders suggested policy measures to address styrofoam debris through brainstorming in the second workshop in 2011. In the third workshop organized in 2012, the analytic hierarchy process (AHP) was used to set priorities for 16 selected policy measures. A total of 56 people participated in AHP, and answers of 40 participants that passed the consistency test were analyzed. 'Beach cleanup by public works program' ranked highest in priority, followed by 'Development of alternative buoy and aquaculture technologies'. Other research projects also ranked high in priority. Feasibility of policy measures was considered the most important criterion in the priority setting, followed by effectiveness, efficiency, and acceptability. This study demonstrated that participatory workshops in which diverse stakeholders take part in could provide a valuable tool in developing practical policy measures on styrofoam buoy marine debris.

Accelerated technological advances and the convergence of information and communication technologies have led to changes of career concepts from one of lifetime employment to that of lifetime career. Given the importance of continuous career development for workers these days, systematic supports for workers' career development at the national level is necessary. Accordingly, a conceptual model of career competency mobility map (CCMM) has been proposed to support the development of workers' career competencies. The purpose of this study is to identify key issues that we should consider for real implementation by applying to each stage of the CCMM conceptual model as a case study. Based on the procedure presented in the conceptual model, the research process which includes collecting user information, conducting self-diagnosis of NCS-based job competencies, deriving necessary training competency, offering the guidance of training programs and job information were conducted. The results of the case study showed our participants' scores of competencies required further development and ranged from 1.83 to 4.52. Sequentially, a personalized information profile was offered for competency development, including training, certificates, and job information. Participants stated that the diagnosis results and profiles were meaningful and helped to explore further career development. Based on the results, implications are suggested.

To identify the gifted, it is essential to perform overall evaluation on cognitive and affective aspects considering all the characteristics of the science gifted. Nowadays, not only cognitive factors but also affective factors are being emphasized. Among the affective factors of the gifted, the task commitment is an important factor to describe the gifted and their outstanding achievements. From this research, by measuring the characteristics of task commitment shown in the science gifted, this can offer good implications regarding the selection of the gifted and the education. We developed the rubric of the gifted students by analyzing the students' experience of showing task commitment. By applying the rubric, we measured the levels by areas of the characteristics of task commitment shown in the experiences which the science gifted had by deeply exploring the cause or the principle. To better understand the characteristics of the science gifted students' task commitment, each and every students' characteristics were specifically described. The students' task commitment can be measured objectively and effectively by using the measuring tool in the form of rubric based on the characteristics of the task commitment. Specifically describing the students' characteristics on the basis of their performance criteria is the grounds for the level judgment and enhances the understanding of the characteristics of students' task commitment.

Since 1992, the sixth national curriculum introduced the policy of school based curriculum development(SBCD) and required all the public elementary schools to develop their own curriculum for the gifted children in their schools. However, in spite of the fact that this curriculum policy for the gifted children has the history of 15 years until now, the current state of its implementation seems to be unsatisfactory. The major reason for that seems to be due to the reality that the schools have not had the theoretical basis for the curriculum development for the gifted children. In this vein, the researcher presented the theoretical SBCD model for the gifted children in elementary schools under the assumption that the model should suit the identity of elementary education, so that the gifted education in the elementary school can be implemented in its own form and adequacy. Based on the identity of elementary education, the model was developed by reformulating three component models of VanTassel-Baska's ICM: content model, process-product model, and epistemological model. The major feature of the researcher's model is to adapt and adjust the three component models differently according to the age level from the first to sixth graders in the elementary school. The model can be used not only as a general model for the talent pool of the school but also as an individual model for a specific gifted child by taking his special needs and characteristics into account. The model is a theoretical one based on the curriculum models for the gifted which were presented by several scholars in the area of G/T education, and it needs to be validated empirically in the future.

Recently, mathematical reasoning has been considered as one of the most important mathematical thinking abilities to be established in school mathematics. This study is to investigate the mathematical problems on the content of 'Set and Statement' and 'Sequences' in high school according to the four types of reasoning, namely Making Conjectures, Investigating Conjectures, Developing Arguments, and Evaluating Arguments. Those types of reasoning were reconstructed based on Johnson's six types of reasoning suggested in 2010. The content is dealt with in 'Mathematics II' textbook developed and published according to the mathematics curriculum revised in 2009. The subject of this study is nine types of textbooks and mathematical problems in the textbook are consisted of as two parts of 'general problem' and 'evaluation problem'. Finally, the results of this study can be summarized as follow: First, it is stated that students be establishing a logical justification activity, the highest reasoning activity through dealing with the 'Developing Arguments' type of problems affluently in both 'Set and Statement' and 'Sequence' chapters of Mathematics II textbook. Second, it is mentioned that students have an chance to investigate conjectures and develop logical arguments in 'Set and Statement' chapter of Mathematics II textbook. In particular, whereas they have an chance to investigate conjectures and also develop arguments in 'Statement', the 'Set' chapter is given only an opportunity of developing arguments. Third, students are offered on an opportunity of reasoning that can make conjectures and develop logical arguments in 'Sequences' chapter of Mathematics II textbook. Fourth, Mathematics II textbook are geared to do activities that could evaluate arguments while dealing with the problems relevant to 'mathematical process' included in 'general problem'.

The traditional mass media function of conveying information and forming public opinion has rapidly changed into an environment in which information and opinions are shared through social media with the development of ICT technology, and such social media further strengthens its influence. In other words, it has been confirmed that the influence of the public opinion through the production and sharing of public opinion on political, social and economic changes is increasing, and this change is already in use on the political campaign. In addition, efforts to grasp and reflect the opinions of the public by utilizing social media are being actively carried out not only in the political area but also in the public area. The purpose of this study is to explore the possibility of using social media based public opinion in educational policy. We collected media data, analyzed the main topic and probability of occurrence of each topic, and topic trends. As a result, we were able to catch the main interest of the public(the 'Domestic Computer Education Time' accounted for 43.99%, and 'Prime Project Selection' topics was 36.81% and 'Artificial Intelligence Program' topics was 7.94%). In addition, we could get a suggestion that flexible policies should be established according to the timing of the curriculum and the subject of the policy even if the category of the policy is same.
