According to the Library Act enacted in 1963, the national bibliography of Korea has been publishing annually since 1965. Unlike countries around the world that have been promoting the continuous development of national bibliography and service innovation, Korean national bibliography is rarely used due to service degradation and structural problems of data. The national bibliography has great significance as a symbol that reflects a country's knowledge culture, as it is a comprehensive records of publications published domestically or related to the country. This study intends to propose a data construction and operation strategy for improving the Korean national bibliography. To this end, this study (1) analyzes trends and key contents of international guidelines for national bibliography, (2) examines the meanings and sustainability of national bibliography at current information environment, and (3) suggests detailed operational strategies to improve the quality and service of Korean national bibliography. Data was collected and utilized through case studies, interviews with stakeholders including national library staffs, and literature reviews.

This research examines the need for a quantitative and objective method of calculating baseline productivity in the construction industry, which is known for its high volatility in performance and productivity. The existing literature's baseline productivity calculation methods rely heavily on subjective criteria, limiting their effectiveness. Additionally, data collection methods such as the "Five-minute Rating" are costly and time-consuming, making it challenging to collect detailed data at construction sites. To address these issues, this study proposes an objective baseline calculation method using unimpacted productivity BP, a work check sheet to systematically record detailed data, and a data collection and utilization process that minimizes cost and time requirements. This paper also suggests using unimpacted productivity BP and comparative analysis to address the objectivity and reliability issues of existing baseline productivity calculation methods.

Recently, there have been research results of applying Big data and AI technologies to the evaluation and individual learning for education. It is information technology innovations that collect dynamic and complex data, including student personal records, physiological data, learning logs and activities, learning outcomes and outcomes from social media, MOOCs, intelligent tutoring systems, LMSs, sensors, and mobile devices. In addition, e-learning was generated a large amount of learning data in the COVID-19 environment. It is expected that learning analysis and AI technology will be applied to extract meaningful patterns and discover knowledge from this data. On the learner's perspective, it is necessary to identify student learning and emotional behavior patterns and profiles, improve evaluation and evaluation methods, predict individual student learning outcomes or dropout, and research on adaptive systems for personalized support. This study aims to contribute to research in the field of education by researching and classifying machine learning technologies used in anomaly detection and recommendation systems for educational data.

Korea has continuously increased investment on R&D to improve global technology competitiveness through technology innovation. Korea's R&D expenditure as a percent of GDP is world's No. 1 as 4.15 and it accomplished 1 trillion won trade volume for 4 consecutive years. However, despite these efforts, technology balance of payment, which is an important factor that can measure nation's technology competitiveness is in a state of chronic deficit and the lowest level among OECD countries. In this paper, we studied methods to improve Korea's technology balance of payment We figured out concept and current state of technology trade and examined the importance of technology trade through making a comparison between commodity trade and technology trade. There have been studies regarding technology trade, but there was no study which tried to figure out cognition on technology trade from the point of view of companies which plays an important role in technology trade. For this, this study distinguished companies with experience in technology trade and which have not and conducted a survey to figure out cognition and current state of companies. The survey result showed noticeable difference on cognition of top decision makers between companies with experience in technology trade and which have not and there are serious shortage in department and staff which is exclusively responsible for technology trade. Also, despite their needs for education regarding technology trade, the ratio of employees who received education is below 10 % of the total respondents. This study suggested improvement methods such as reforming survey methods of technology trade statistics, enhancing social cognition, supporting to vitalize technology export, building infrastructure regarding technology trade, and opening education programs for cultivating experts based on preceding research and industry survey.

This research is an investigation of difficulties encountered by authors of 5th and 6th grade science textbooks. The aim is to assist authors in creating more easily understandable textbooks in the future. In-depth interviews were conducted with 6 teachers who have previously taken part in the development of 5th and 6th grade texts. The responses given during these interviews were analyzed using open, axial, and selective coding as suggested by Strauss and Corbin (1998). The results are as follows: In open coding, related concepts were extracted and classified into 15 main categories and 46 sub-categories. In axial coding, the main categories were arranged into causal conditions, main phenomenon, context, intervening conditions, action and interactional strategies, and consequences wherein they were consistently related to each other based on Grounded theory. Finally, in selective coding, core categories were instilled whereby the texts being developed were categorized into conservative, progressive, and innovative to allow for easier interpretation. This was done to improve the overall quality of Science textbooks.

The purpose of this study was to delve into parents who turned their children into creative achievers in the East and the West in an attempt to determine the cultural generality and specificity of the rearing of gifted children. The subjects in this study were Western parents, who brought up Marie Curie, Einstein, Edison and Newton, and Eastern parents, who raised Lee Hwang, Lee lee, Jeong Yak-yong and Heo Nanseolheon. To compare their parenting characteristics, common denominators and differences, a variety of data were investigated, including historical records about the parents, biographies, critical biographies, autobiographies and letters. As to the common features of the parenting style of the eight Asian and Western parents, they were talented themselves or capable of educating their children in their talent areas, and provided them with optimal learning environments or chances without pushing them. They accentuated independent spirits and emphasized renovative and open way of thinking. And at least one parent in each family showed absolute support for their child. Regarding differences in parenting style between the East and the West, the Western parents urged their children to develop their talents with more intention, rather the Asian parents prized the well-rounded personality and growth of their children. The former interacted with their children in an horizontal manner, but the latter had a vertical relationship with their children. The former expressed their feelings in an active way, but the latter had their emotion in control. Besides, the Western parents disclosed themselves to their children by showing them even their mistakes or improper behaviors, whereas the Asian parents strived in everyday life to give their children a good example or a good role model.
