AI-URG: Account Identity-Based Uncertain Graph Framework for Fraud Detection

Cybercriminals controlling multiple accounts to conduct malicious activities are a threat to the security of online services. These accounts form malicious communities that are difficult to detect using conventional methods with single-factor identity, such as browser fingerprint or internet protocol (IP) address. Single-factor identity is prone to noise and uncertainty and does not capture dynamic relationships between accounts. To solve the problems of insufficient single-factor identity and uncertainty binding between accounts and identity, we propose Ai-Urg, a novel account identity-based uncertain graph with multifactor identity modeling for online service fraud detection. To find account groups, we embed account representation that preserves the uncertain graph’s possible world semantics and use the domain knowledge that accounts of family members also from small communities to filter these benign groups and detect malicious communities. The ablation study demonstrates how each component contributes to the effectiveness of Ai-Urg. The comparison results on two datasets show that Ai-Urg outperforms the alternatives with a higher F1-score (58.0%) and precision (46.0%) on a real-world online bank dataset and with a higher F1-score (36.5%) and precision (96.9%) on a large-scale single-sign-on online service dataset. The experimental results can provide valuable insights into online service fraud detection.

Analysis of the Enactment Process of 「Jeollabuk-do School Autonomy Ordinance」: Based on Kingdon’s Policy Stream Model

The purpose of this study is to analyze the dynamic enactment process of the 「Jeollabuk-do School Autonomy Ordinance」enacted in 2019 using Kingdon's policy stream model. The stream of policy issues includes indicators of the necessity of legal organization of school autonomous bodies, attempts to enact school autonomy ordinances by each city/provincial office of education, and feedback due to the limitations of the existing school autonomy operation. The stream of politics includes changes in the provincial atmosphere for school autonomy, the emergence and interest of a new administration, and the activities of interest groups in school autonomy ordinances. The stream of policy alternatives includes the proposal of Jeollabuk-do Office of Education, the proposal of Korean Teachers and Educational Workers' Union, the proposal of Korea Federation of Teacher's Associations, and the proposal of private school corporations and principals. These policy alternatives were influenced by policy communities such as teachers' organizations, teachers' unions, and school corporations. These three independent streams were combined as the change of administration became the trigger mechanism. In addition, as progressive policy entrepreneur such as the Jeollabuk-do Superintendent of Education is actively working to urge the enactment of the ordinance, the working-level council for promoting the school autonomy ordinance was held on March 26, 2018, combining these three streams to open a policy window. As a result, the Jeonlabuk-do School Autonomy Ordinance, which has been under legislative discussion for a long time, was finally enacted on February 1, 2019.
Analysis of Policy Process in Seoul Innovation Education District : Focusing on Kingdon's Multi-Flow Model

This study aims to re-examine policy development plans and derive implications by analyzing the policy agenda setting process and policy decision process using Kingdon's policy flow model for the Seoul Innovation Education District, which is different from other educational policy projects. Accordingly, the analysis period was set from 2010 when the innovation education district policy was proposed to 2015 when the Seoul-type innovation education district policy was started until recently, and Bigkinds analysis and related literature analysis were conducted. As a result of the analysis, the flow of policy issues was constantly raised due to complaints about public education, controversy over welfare direction in education, school violence, and suicide rate, and the flow of policy alternatives was analyzed as attempts to spread the performance of innovative schools to general schools, bridge the educational gap, and the growth of the village education community. The flow of politics was analyzed as the biggest trend of the direct election system of the superintendent of education, and it was analyzed that the combination of these flows opened a total of three times. As the first policy window was introduced, the Seoul Innovation Education Zone policy was implemented with the first election of the liberal Seoul Superintendent in 2012, and the second policy window was analyzed to have laid the legal basis for the project with the enforcement of the Seoul Innovation Education Zone Ordinance in 2016. The last window of the third policy was analyzed that all autonomous districts in Seoul implemented the Seoul Innovation Education District project in 2019 and the project was expanded. Based on the analysis results, first, the initial purpose of the Seoul Innovation Education District policy should not be lost. Second, it is necessary to organize the concept of the village education community and establish a system that can be actively and autonomously operated. Third, it drew implications for considering the sustainability of the Seoul Innovation Education District policy, which has a strong influence on the political flow, and finding alternatives.
Analysis of the Trend and Relationship between General Grant for Local Education and the Number of Students: Implications for the Statutory General Grant Rate of Jeju Special Self Governing Provincial Office of Education

During 2013-21, this study analyzed the trend of increase and decrease in the number of students, schools, classes, and teachers, which are measurement units for calculating General Grant for Local Education, and the relationship between General Grant and the number of students. Based on the analysis results, it was discussed whether the statutory rate of General Grant for Local Education ordinary subsidies of the Jeju Office of Education was appropriate. As a result of the analysis, first, Jeju's General Grant remained at 1.57% of the total amount of General Grant in most cases with some exceptions. Considering the increase of the number or proportion of students, classes, schools, and teachers, which are major measurement units for calculating General Grants, the statutory grant rate in Jeju, which has been fixed at 1.57% since 2007, should be raised. Second, as a result of estimating the relationship between General Grants and the number of students, students per class, and students per school with a fixed effect model, students per class and students per school had a significant effect on the size of General Grants. As the number of students per class decreased and students per school increased, the average General Grants increased. The decrease rate of the number of students per class in the Jeju Office of Education is lower than the national average, which seems to be due to insufficient educational finances. It might be necessary to increase General Grants of the Jeju Office of Education. As the rate of decrease in the number of students per school was lower than the national average, the effect of this decrease in General Grants is expected to be relatively small. Based on the research results, there is a high need to raise the statutory General Grant rate of Jeju Office of Education.
Analysis of the perceptions on the improvement of the Teacher Evaluation system

This study was conducted for the purpose of examining perceptions and finding the right direction for future teacher evaluation system. In order to achieve the research purpose, an interview survey was conducted with interested parties who participated in the evaluation after the completion of the evaluation of teacher competency development in 2021. As a result of the study, the overall positive perception of system improvement was high, but negative perceptions and concerns were also significant. It was suggested that system improvement through more in-depth research and investigation was necessary for matters in which there was a particularly large difference in perceptions between the evaluation subjects(between teachers and parents) regarding the same system improvement items. Based on the research results, it is suggested to establish a plan for using specific evaluation results to enhance the professionalism of teachers, design customized evaluation questions for evaluation purposes and evaluation subjects, and seek ways for each school level, region, and evaluation subject to increase the evaluation participation rate. did.
A Exploratory Study on the Improvement of School Governance through the Management System Theory of Likert

This study analyzed the components of school governance in Korea using the management system theory of Likert (1976). In school governance, organizations such as student associations, teachers' associations, and parents' associations and organizations such as school management committees that connect each subject to each other have a multi-overlapping structure. The structure of school governance in Korea has a linking pin structure emphasized in System 4, but it can be seen that the level of the system is determined by which stage each subject acts in the system decision variable proposed by Likert (1976). Therefore, as a way to improve the effective operation of school governance, first, all participating entities in school governance should create a shared vision and achieve cognitive and emotional consent. Second, the horizontal and democratic consciousness of school managers should be deeply rooted in the entire organization. Third, decision-making authority should be equally distributed to all subjects. Fourth, at the level of the communitiy of village education, it is necessary to systematically supplement the linking pin structure that closely connects unit schools, communities, and basic local governments.
Research Trends on Performance Management of University Organizations: Focus on research in the development of performance management models

The overall trend of research on university organization performance management was divided into the number of research papers, research subjects, research methods, and research topics. The conclusions made based on the main research results revealed in this study are as follows. First, it is necessary to conduct research on the effectiveness of the case or developed model, along with research on the introduction of the performance management system of university organizations. Second, it is necessary to conduct a study to develop a performance management model for the entire university organization by reflecting the characteristics of the university organization. Third, in conducting research on developing a performance management model of a university organization, it is necessary to develop a model that synthesizes the advantages of various models, not based on only one specific model. Fourth, in research on the performance management of university organizations, it is necessary to use research methods suitable for research topics and to actively conduct literature research.
Exploring the Empirical Episodes of Teacher Training for the Development of Teacher Professionality

This study aims to draw implications for the developmental management of teacher training policies by asking teachers' empirical perceptions about teacher training in terms of professional development. To attain the aims, by using FGI, the empirical perception of teachers on teacher training in the aspect of professional development, the empirical perception of teachers on the current teacher training policy, and the empirical requirements for future teacher training policy were explored. The main analysis results are summarized as follows. Teachers agreed on the need for training. Through training, professionalism was increased and human networks were formed. There was no difference in professional development depends on the type of training. In terms of teacher training policy, the lack of prior discussion on professionalism, difficulty to know whether teacher training condidering the life cycle is appled, lack of quality control, gap with the field, and lack of operational support were pointed out. For the development of teacher training policy, it is necessary to discuss professional development, provide practical training considering the life cycle, manage the quality of training, develop contents that reflect the needs, customized training, establish a future-oriented training system, and make efforts to support training. Based on these results, conclusions were drawn on the matters to be considered in the future teacher training policy.
Analysis of research trends on the relationship between the teaching profession and teachers' professional capital influencing factors and teacher’s professional development activities

This study analyzes the preceding studies on professional capital presented by Hargreaves and Fullan (2012), examines the factors influencing the formation of professional capital covered in previous studies, and find out the case of professional capital construction through teacher professional development activities. The purpose of this study was to suggest the direction of future research related to professional capital. As a result of the study, teachers' gender, career, academic background, school satisfaction, teacher job satisfaction, and principal's leadership were used as the influencing factors of professional capital in the most studies, and it was found that they had a significant influence on the formation of professional capital. Teacher professional development activities include teacher learning community, educational practice, and teacher evaluation. The formation of professional capital through teacher learning community and school field-practice was found, but professional capital was not formed through teacher evaluation. Based on these results, the direction of future research on professional capital and the improvement direction of teacher professional development activities were suggested.
Latent Groups of Vocational Teachers’ Digital Competence: Relationship between individual characteristics and the type of technology integration

본 연구는 직업계고 전문교과 교사의 디지털 역량 잠재집단을 분류하고 개인의 태도, 연령, 학습경험, 디지털 기술 활용 실습지도 유무가 잠재집단 구분에 미치는 영향력 및 잠재집단별 디지털 기술 활용 형태의 차이를 분석하였다. 이를 위해 2022년 7월 1일부터 7월 20일까지 직업계고에 재직 중인 전문교과 교사 1,091명을 대상으로 설문조사를 실시하였으며 수집된 자료를 토대로 잠재프로파일분석 및 예측변인과 결과변인 검증을 실시하였다. 분석 결과 첫째, 직업계고 전문교과 교사의 디지털 역량 잠재집단은 총 3개로 분류되었으며, 디지털 역량 지표변인의 점수를 고려하여 각 집단 명칭을 상위수준 집단(24.8%), 중간수준 집단(63.8%), 하위수준 집단(11.4%)으로 명명하였다. 둘째, 직업계고 전문교과 교사의 디지털 역량 잠재집단 분류에 유의한 영향을 미치는 개인 특성 변인을 확인한 결과 디지털 기술 활용에 대한 긍정적 태도를 가질수록, 연령이 낮을수록, 학습 경험을 가지고 있을수록, 전공에서 컴퓨터 및 소프트웨어 실습 지도를 하고 있을수록 디지털 역량 상위수준 집단에 속할 가능성이 높았다. 셋째, 디지털 역량 잠재집단별 디지털 기술 활용 형태를 분석한 결과 하위수준 집단보다 중간수준 집단에서, 중간수준 집단 보다 상위수준 집단에서 3가지 형태(내용전달 목적의 활용, 수업 다양화 목적의 활용, 수업 혁신 목적의 활용)의 활용 수준이 모두 높게 나타났다. 디지털 역량 하위수준 집단에서는 주로 내용 전달 목적의 활용 위주로만 디지털 기술 활용이 이루어지고 있음을 확인하였다. 본 연구의 이러한 결과는 전문교과 교사들의 태도나 디지털 기술 활용 실습지도 유무, 학습 경험 유무 등에 따라 디지털 역량과 디지털 기술 활용 형태가 달라질 수 있음을 시사한다. 이를 토대로 직업계고 전문교과 교사의 디지털 역량 증진을 위한 정책적 시사점을 제안하였다.The purpose of study is to identify the latent groups of vocational teachers' digital competence and analyze predictor variables(attitude, age, learning experience, characteristics of major) and outcome variables(type of technology integration). To this end, a survey was conducted on 1,091 vocational teachers from July 1 to July 20, 2022, and a three-steps latent profile analysis(LPA) based on the collected data. The results are as follows; First, the digital competence of vocational teachers was categorized into three potential groups, each of which was named the upper group(24.8%), the middle group(63.8%), and the lower group(11.4%). Second, we found that attitudes, age, learning experience and characteristics of major all had a significant effect on the classification of digital competence latent groups. The more positive the attitude, the younger the age, the more learning experience, and the more computer and software experience in their class, the more likely they were to be in the upper group. Third, as a result of analyzing the types of technology integration by digital competence latent groups, all three types(technology use for delivery, technology use for enrichment, technology use for transformation) were highest in the upper group. It was confirmed that lower group of digital competence was mainly used technology for content delivery purposes. Based on this, policy implications for improving the digital competence of vocational teachers were proposed.
