This paper analyzes the role of green finance in promoting sustainable development and climate change adaptation in Danang, particularly in the context of the city's strategic orientation toward becoming an International Financial Center based on two pillars: digital finance and green finance. Drawing on theoretical foundations, local practices, and international experiences, the study highlights that while Danang has made initial efforts—such as partnering with BIDV and developing Eco-industrial parks in collaboration with GIZ and UNIDO—it still lacks a dedicated legal framework, domestic green financial instruments, and sufficient implementation capacity.......

Keywords: Green finance, sustainable development, climate change, Danang, urban.

The rapid growth of digital technologies has driven the digitalization of human- resource management, leading to the increasing use of electronic labor contracts in enterprises. Vietnamese law recognizes the legal validity of electronically concluded labor contracts; however, several legal challenges remain regarding electronic signatures, evidentiary value, data integrity, personal data protection, and the parties' responsibilities in dispute resolution. This article analyzes the current legal framework governing e-labor contracts, examines practical issues in enterprise implementation, and proposes recommendations to enhance legal certainty and compliance in the digital labor environment.

Keywords: Electronic labor contracts; electronic transactions; electronic signatures; personal data; labor relations; labor law; enterprise digital transformation.

This article introduces one of the teaching methods that is very meaningful in enhancing the students' positivity: using practice, practical questions to connect the lesson content with life to stimulate students' interest in the subject of General Physics. Through the article, the author presents the use of practical problems, practical questions in the Applied Mechanics section in the teaching of General Physics, helping students see the practical benefits of studying Physics to develop curiosity, stimulate thinking, exploration, improve self-study, self-thinking of students at the Vietnam - Korea University of Information Technology and Communications.

Keywords: Practical, practical question system; Active teaching ; Interest.

This paper offers a scholarly and exhaustive examination of cryptanalysis, a principal discipline within cryptology. Functioning as the analytical counterpart to cryptography, cryptanalysis systematically interrogates cryptographic algorithms, protocols, and ciphertexts with the aim of identifying latent structural vulnerabilities and evaluating the robustness of security mechanisms.The study formalizes key conceptual distinctions most notably the differentiation between cryptanalytic methodologies and brute-force techniques and establishes a rigorous classification of attack models predicated on the adversary's informational advantage.......

On the background of analyzing the current integration and implementation status of "artificial intelligence+teaching", this paper proposes the idea of constructing a personalized classroom teaching mode with interpretable artificial intelligence. In response to the research question, we design an overall framework for personalized classroom teaching using interpretable "artificial intelligence+teaching", which includes three parts: interpretable artificial intelligence clustering method, student-interest based classroom teaching mode, and interpretable artificial intelligence classroom teaching evaluation system..........

Keywords: Interpretable, artificial intelligence, personalized, classroom teaching.
