Compared to research on the success of IT projects in general, research on the management of conflict in IT teams and its impact on project success is insufficient. This research performed a comparative study to analyze the nature and evolving phenomenon of conflicts in IT project teams. This study aimed at; First, Why a conflict is created within and around an IT project team. Second, What is the phenomenon of conflict evolution, diffusion, and/or resolution? Third, How the differences in conflict management style affects the IT project performance? Three propositions were drawn from the analysis of two intensive analysis of conflict cases and their comparison. Proposition 1 : Both 'the method of pointing out a problem' and 'the pointed-out contents' can be the trigger of conflicts around an IT project. Proposition 2 : While the focus of attention of one party is 'the method of pointing out a problem', if the other's and focus of attention of one party is 'the pointed-out contents', that is, if the focus of attention mismatch, the conflict can be amplified. Proposition 3 : According to the temporal nature of the relationship, e.g., short-term versus long-term, the way people approach and deal with the conflict differs.

기하적 성질을 이해하고 받아들이는 데 있어서 중요한 직관은 학습을 통해서도 형성될 수 있다. 본 연구는 2명의 학생을 대상으로 기호화, 문장화, 증명 과제를 수행하게 하여 기하 증명에서 기호의 중재에 의한 직관의 형성 과정을 살펴본다. 학생들에게 자명하고 당연하게 여겨지는 단정적 직관의 유무에 따라 기호가 어떤 역할을 하는지 살펴보고, 예상적 직관이 형성되지 않은 증명 문제에서 학생들이 기존 지식을 활용하여 증명을 완성하는 과정을 기호의 의미작용에 의해 설명한다. 마지막으로 피타고라스의 정리에 대해 기호의 중재에 의해서 결론적 직관이 형성되는 과정을 살펴본다.

As technology advances, the amount of fake news is increasing more and more by various reasons such as political issues and advertisement exaggeration. However, there have been very few research works on fake news detection, especially which uses grammatical transformation on deep neural network. In this paper, we shall present a new Fake News Detection Model, called FAGON(Fake news detection model using Grammatical transformation On deep Neural network) which determines efficiently if the proposition is true or not for the given article by learning grammatical transformation on neural network. Especially, our model focuses the Korean language. It consists of two modules: sentence generator and classification. The former generates multiple sentences which have the same meaning as the proposition, but with different grammar by training the grammatical transformation. The latter classifies the proposition as true or false by training with vectors generated from each sentence of the article and the multiple sentences obtained from the former model respectively. We shall show that our model is designed to detect fake news effectively by exploiting various grammatical transformation and proper classification structure.

마틴뢰프의 직관주의적 유형론의 중요 사항들을 설명하고, 그 체계의 가장 중요한 특성 중의 하나인 명제와 판단의 구분에 관해 검토한다. 1절에서 문제를 도입한 후, 2절에서 직관주의적 유형론의 명제개념은 직관주의적 명제개념의 발전된 형태임을 보이고, 3절에서는 직관주의적 유형론에서 가장 기본적인 판단개념을 설명한 후, 4절에서 직관주의적 유형론의 기본적인 추론규칙들을 설명하고 그 적용의 한 사례를 검토할 것이다. 마지막으로 5절에서, 직관주의적 유형론에서 명제와 판단의 구분이 차지하는 중요성을 부연한 후, 기초론적 체계에서 명제와 판단의 구분이 필수적인지의 문제와 관련하여, 통상적인 프레게적 구분으로부터 시작하여 직관주의적 유형론에서와 같은 구분에 이르기 위해서는 어떤 것들이 전제되거나 정당화되어야 하는지 검토할 것이다.

Purpose: This study explores the impact of digital transformation (DT) strategies on gaining a competitive advantage in interactive educational services. Methods: We develop a service value proposition model by analyzing educational service elements to confirm the impact of DT in the classroom through case studies. This study focuses on educational services that DT has a positive impact on organizational competitiveness by providing opportunities for customers to engage in operational processes. This case study summarizes competitiveness using SWOT (strengths, weaknesses, opportunities, and threats) analysis. Results: The findings of the case study indicate that DT-enabled competitive factors contribute to an organization's competitive advantage. The study results present key resource as social cloud services, data combination, content sharing, and products/services. The online application that collects user data about education and shares class and evaluation information creates a new class operational process in the field of educational service for a value proposition of collection-merging-sharing with social cloud function. Conclusion: The results of this study can be used as a good guideline for educational service providers interested in applying DT for improved customer satisfaction and educational organizations' competitiveness. In addition, the study findings provide theoretical and practical implications on SWOT approaches to changing the educational service provision ways through digital transformation.

Researchers continue to emphasize the centrality of proof in the context of school mathematics and the importance of proof to student learning of mathematics is well articulated in nationwide curricula. However, researchers reported that students' performance in proving tasks is not promising and students are not likely to see the need to prove a proposition even if they learned mathematical proof previously. Research attributes this issue to students' tendencies to accept an empirical argument as proof for a mathematical proposition, thus not being able to recognize the limitation of an empirical argument as proof for a mathematical proposition. In Korea, there is little research that investigated high school students' views about the need for proof in mathematics and their understanding of the limitation of an empirical argument as proof for a mathematical generalization. Sixty-two 11^th graders were invited to participate in an online survey and the responses were recorded in writing and on either a four- or five-point Likert scale. The students were asked to express their agreement with the need of proof in school mathematics and to evaluate a set of mathematical arguments as to whether the given arguments were proofs. Results indicate that a slight majority of students were able to identify a proof amongst the given arguments with the vast majority of students acknowledging the need for proof in mathematics.
