IDL-LTSOJ: Research and implementation of an intelligent online judge system utilizing DNN for defect localization

The evolution of artificial intelligence has thrust the Online Judge (OJ) systems into the forefront of research, particularly within programming education, with a focus on enhancing performance and efficiency. Addressing the shortcomings of the current OJ systems in coarse defect localization granularity and heavy task scheduling architecture, this paper introduces an innovative Integrated Intelligent Defect Localization and Lightweight Task Scheduling Online Judge (IDL-LTSOJ) system. Firstly, to achieve token-level fine-grained defect localization, a Deep Fine-Grained Defect Localization (Deep-FGDL) deep neural network model is developed. By integrating Bidirectional Long Short-Term Memory (BiLSTM) and Bidirectional Gated Recurrent Unit (BiGRU), this model extracts fine-grained information from the abstract syntax tree (AST) of code, enabling more accurate defect localization. Subsequently, we propose a lightweight task scheduling architecture to tackle issues, such as limited concurrency in task evaluation and high equipment costs. This architecture integrates a Kafka messaging system with an optimized task distribution strategy to enable concurrent execution of evaluation tasks, substantially enhancing system evaluation efficiency. The experimental results demonstrate that the Deep-FGDL model improves the accuracy by 35.9% in the Top-20 rank compared to traditional machine learning benchmark methods for fine-grained defect localization tasks. Moreover, the lightweight task scheduling strategy notably reduces response time by nearly 6000ms when handling 120 task volumes, which represents a significant improvement in evaluation efficiency over centralized evaluation methods.

Institutional Determinants for Developing Corporate Crowdfunding

This article focuses on the regulation of investment crowdfunding as a key criterion for the dynamic but safe development of this form of business financing. The intensive, uncontrolled development of innovation in financial markets generally leads to irregularities (fraud, abuse, crises). In turn, excessive and restrictive regulation can act as a brake on the development of financial innovation. Due to the subject matter of the study, which is the regulation of equity crowdfunding as well as equity crowdfunding itself, the methodology of the study consists primarily of research of source data available online. A literature review of the regulation of innovation in financial services was conducted. This includes the identification and review of academic articles, research reports, books, industry publications and other authoritative sources. This synthesis of information helps to define an appropriate benchmark for the regulation of European crowdfunding, identifying patterns and challenges for effective, pro-development regulation. Author presents the equity crowdfunding regulations of the US and the UK – the world’s number 1 and 2 crowdfunding markets – as a benchmark for the proposed pan-European regulations. The features of the common European rules seem to meet the requirements. And the increase of the funding amount to EUR 5 million opens up completely new possibilities for equity crowdfunding.

Heat Transfer Characteristics of a Hot‐Rolled Seamless Steel Tube During a Controlled Cooling Process

Owing to special annular section shapes, the controlled cooling technology widely used in the field of steel plates is difficult to develop successfully and apply stably in the field of steel tubes. In this research, a finite element simulation method is used to study the difference in flow field distribution between a steel plate and a steel tube with jet cooling. Combined with the heat transfer characteristics of the jet cooling process at different positions, the anisotropy of the cooling heat transfer on the outer surface of a steel tube is revealed. The heat transfer characteristics of the inner and outer walls of a high‐temperature steel tube with the condition of simultaneous cooling are further analyzed. The results show that with the increase of the steel tube rotation speed, the temperature gradient between the wall of steel tube and the center position shows a decreasing trend. With the increase of the axial water velocity, the heat transfer intensity of the inner wall shows an increasing trend. The theoretical research results are successfully applied to the research and development of online controlled cooling technology and the equipment of hot‐rolled seamless steel tubes, and this achieves good application performance.

ONLINE SHOPPING PERCEIVED RISKS DURING THE COVID-19 PANDEMIC: ON THE STUDENT’S CASE FOR THE APPAREL AND FOOTWEAR

The purpose of the article is to develop and test a methodological approach to assess the impact of the online shopping perceived risks during the COVID-19 pandemic: on the student’s case for apparel and footwear. The study used a set of general and special methods of cognition: logical generalization, qualimetric comparison, taxonomic and index analysis, graphical visualization, scientific abstraction, and systematization of data. Online shopping is now a widespread and popular sales channel of an extremely large range of consumer goods in almost all regions and countries of the world, especially in developing countries. The online sales segment in the Ukrainian apparel and footwear market has high growth rates and development prospects. The purpose of the article is to determine the perceived risks while shopping Apparel and Footwear (AF) online during a COVID-19 pandemic. To collect primary information, 634 students of Ukrainian and foreign universities were surveyed. Information processing was carried out by applying methods of mathematical statistics. The main conclusions of the study relate to both the theoretical foundations of consumer behavior and their practical aspects. Firstly, the majority of respondents, regardless of the difference in their socio-demographic characteristics, positively perceive online shopping as a protective measure against infection with the COVID-19 virus. Secondly, as for consumer sentiment in the post-quarantine period, we can expect further growth of Internet trade in AF, as almost a third of respondents are going to buy more than before quarantine, and their number is 2-3 times higher than the number of those who have the intention to buy less. Thirdly, the ranking of perceived risks while shopping AF online allowed us to identify the most important ones, namely the risks associated with the product itself (risks of improper quality of goods, and financial ones) and the risk caused by the online shopping process - the risk of unsuccessful return of goods to the seller. This study provides practical confirmation for understanding the risks of online trade-in AF. The results of the study will contribute to the adoption of scientifically based decisions by the management of online stores and future research of online shopping processes by scientists.

Narratives, Myths and Sense of Place in the Public Image of Three Festivals in Bulgaria

The object of this study is the public image of three local festivals in Bulgaria: the Festival of Rose in Kazanlak, July Morning in Kamen Bryag and the Festival of Peppers, Tomatoes, Traditional Foods and Crafts in Kurtovo Konare. The public image of the three festivals is decomposed to the following elements for the sake of the analysis: narrative (history, myth), human factor, sense of place and public communication. The methods included participant observations, in-depth interviews, desk research of scientific literature, online and social media. The study revealed that the Festival of Rose in Kazanlak is part of an integrated cultural and tourist product, identified with the good local governance. July Morning in Kamen bryag, once a celebration of an alternative sub-society, has been commercialized towards fragmented (dispersed) festive events which obscured the sense of community and the sense of place affiliated with the initial phenomenon. Local farmers with their inherent sense of identity, agrarian knowledge and willingness to associate at a local level, play a central role in the publicity of Kurtovo Konare Fest. Local festivals share a distinctive feature: striving for the well-being of the local community. The result is an increase in the reputation of the region, attracting of media attention, awakening of the real estate market, spatial rehabilitation, improvement of road infrastructure, expansion of tourism opportunities and strengthening of networks for civic participation. This abstract is based on results within the project “Local Festivals: A Resource of Local Communities for Coping with Crises”, funded by the National Scientific Fund of Bulgaria – Ministry of Education (KP-06-H45 / 5 of 30.11.2020).

Research and Practice of Online and Offline Mixed Classroom Teaching of Pathology Based on Computer Technology

We can see that the teaching method of pathology in the old times was very single. According to the students’ reaction, the traditional teaching method and its effect are very poor. To some extent, it may limit students’ initiative thinking and creative thinking. This is a very unfavorable way to cultivate innovative talents. In order to meet the needs of Pathology Teaching in today’s society, people invented a mixed classroom teaching mode of online teaching and offline teaching[1]. Online teaching and offline teaching mode is a new teaching method that connects offline general teaching with Internet platform. With the support of computer technology, many medical schools have begun to implement the mixed teaching mode of pathology teaching. According to statistics, this teaching process can promote the learning of pathology.

Looking At Screens: Examining Human-Computer Interaction and Communicative Breakdown in an Educational Online Writing Community

This study, a qualitative examination of students’ experiences within an online writing community, frames human-computer interaction (HCI) as a dialogic negotiation of users and systems within networked publics. It demonstrates how an interface-level examination of these interactions, particularly at moments of glitch and error, reveals their impact on the landscape and design of educational online writing communities, puncturing the technological transparency that permeates HCI. Using a micro-ethnographic approach, this study draws from screen capture recordings, questionnaires, observations, and visual-elicitation interviews to construct two cases that demonstrate the significance of interface-level interactions in shaping the networked public square of an educational online writing community, re-framing conceptualizations of both student and system “error.” By encouraging readers to look at (rather than through ) the interfaces mediating students’ interactions with online writing communities, this article shows how interface-level interactions emerge from and fold back into complex dialogic systems with implications for the teaching, research, design, and analysis of educational online writing communities.

Capital or the Capitol? The Hunger Games Fandom and Neoliberal Populism

Abstract: Based on interviews with fans of the Hunger Games books and films, and research of reader reviews and commentary online, this article argues that the widespread agreement among otherwise polarized fans indicate a change in populism in the US toward an anti-statist framing of social inequality defined as neoliberal populism.The essay connects the Hunger Games to other examples of westerns that allegorize class inequality through rural/metropolitan divisions. It provides examples of three primary reader interpretations of the series as roughly analogous to contemporary American political positioning, with liberals and progressives who read THG as supporting an interracial struggle of the have-nots against the wealthy haves; by Conservatives and radical white nationalists who read the series as advocating rural struggle against totalitarian and cosmopolitan liberal fascism and by revolutionary third-worldists who see the primary characters anti-colonial rebels against US empire.
