Using Blockchain to Achieve Decentralized Privacy in IoT Healthcare

With the advent of the Internet of Things (IoT), e-health has become one of the main topics of research. Due to the sensitivity of patient information, patient privacy seems challenging. Nowadays, patient data is usually stored in the cloud in healthcare programs, making it difficult for users to have enough control over their data. The recent increment in announced cases of security and surveillance breaches compromising patients' privacy call into question the conventional model, in which third-parties gather and control immense amounts of patients' Healthcare data. In this work, we try to resolve the issues mentioned above by using blockchain technology. We propose a blockchain-based protocol suitable for ehealth applications that does not require trust in a third party and provides an efficient privacypreserving access control mechanism. Transactions in our proposed system, unlike Bitcoin, are not entirely financial, and we do not use conventional methods for consensus operations in blockchain like Proof of Work (PoW). It is not suitable for IoT applications because IoT devices have resourcesconstraints. Usage of appropriate consensus method helps us to increase network security and efficiency, as well as reducing network cost, i.e., bandwidth and processor usage. Finally, we provide security and privacy analysis of our proposed protocol.

Gender stereotypes in ecological research themes: An analysis of the last 20 years of the Argentinian ecology conferences

AbstractAlthough Argentina harbours a notable increase in the academic community, achieving the highest number of researchers per capita in Latin America, the gender gap is still evident. The objective was to identify and evaluate the evolution of the main research themes in Argentinian ecology during the last 20 years to address whether social gender stereotypes were reproduced in research theme selection. We analysed four books of abstracts from the Argentinian Ecology conferences of the last 20 years and identified gender of the first author and co‐authors. Natural Language Processing approach was used to analyse gender associations with the 16 319 words appearing in the 2208 titles of abstracts. The average number of female co‐authors was always larger in female‐led abstracts although the proportion of female co‐authors/total authors increased the most in male‐led abstracts. Research themes evolved from those considered cornerstones of ecology (e.g. population‐oriented studies) to contemporary themes defined by Management and policy studies. Gender differences were present and changed with time. Currently, men work on research themes related to decision‐making, while women focus on environmental processes therefore it is urgent to create more leadership spaces for women to reduce gender inequalities.

Emerging trends and focus on the link between gut microbiota and type 1 diabetes: A bibliometric and visualization analysis.

To conduct the first thorough bibliometric analysis to evaluate and quantify global research regarding to the gut microbiota and type 1 diabetes (T1D). A literature search for research studies on gut microbiota and T1D was conducted using the Web of Science Core Collection (WoSCC) database on 24 September 2022. VOSviewer software and the packages Bibliometrix R and ggplot used in RStudio were applied to perform the bibliometric and visualization analysis. A total of 639 publications was extracted using the terms "gut microbiota" and "type 1 diabetes" (and their synonyms in MeSH). Ultimately, 324 articles were included in the bibliometric analysis. The United States and European countries are the main contributors to this field, and the top 10 most influential institutions are all based in the United States, Finland and Denmark. The three most influential researchers in this field are Li Wen, Jorma Ilonen and Mikael Knip. Historical direct citation analysis showed the evolution of the most cited papers in the field of T1D and gut microbiota. Clustering analysis defined seven clusters, covering the current main topics in both basic and clinical research on T1D and gut microbiota. The most commonly found high-frequency keywords in the period from 2018 to 2021 were "metagenomics," "neutrophils" and "machine learning." The application of multi-omics and machine learning approaches will be a necessary future step for better understanding gut microbiota in T1D. Finally, the future outlook for customized therapy toward reshaping gut microbiota of T1D patients remains promising.

A Study on Thinking about Career Cognitive Planning Education for College Music Students

Music major college students are a unique group in both general universities and conservatories. They have strong personalities, rich feelings, and have the youth and vitality of art students. Therefore, it is of great relevance to develop career education based on the main characteristics of music major college students. For music majors, there are relatively various career paths, such as music education, performance, broadcasting, media, and other industries. Therefore, the “employment issue” for most music majors has become one of the more popular topics at present. This paper explores the current career planning as well as career awareness of music college students by using 259 college students enrolled in the Department of Music of Inner Mongolia Normal University in 2017 and 2018 as the main research subjects. The results show that only 6% of music major college students know a lot about employment policies, and still 38% of music major college students know less about employment policies as well as career awareness. The results show that the overall status of career planning development of music majors is at an intermediate level and still needs to be improved. Therefore, it is very meaningful and important for universities to strengthen the career planning education for music majors’ career awareness.

Public–Private Partnerships in Urban Regeneration Projects: A Review

With the changing paradigm of the State’s functions and the increasing private sector participation in urban planning, public–private partnership (PPP) arrangements gain prominence in the development of cities, whether in the construction and operation of new infrastructures or in interventions in urbanized areas. Regarding urbanized areas, urban regeneration practices constitute an important response in the face of urban degradation observed in different cities, as well as an alternative to the consumption of new land. Despite their use in different contexts, the PPP option in urban regeneration projects encounters many obstacles related to high investment risk, low financial and social return, and the numerous sources of uncertainty generated by these projects. The present work consists of a systematic literature review of papers on PPP in urban regeneration projects, seeking to identify the main research topics addressed so far and what gaps can be identified. It uses a hybrid methodology considering a systematic quantitative review, a semantic analysis, and a narrative analysis. The findings show that the literature on the topic is recent and has been increasing in recent years, with emphasis on Europe, followed by North America and Asia. The literature presents a high variety in terms of journals, authors, and institutions. As for the methodology adopted in the articles, it highlights the use of quantitative methodologies. Five main topics were found: policy, projects, governance, financial and economic issues, and management and contract issues. The topics found show the complexity of PPPs in urban regeneration projects. The gaps observed refer mainly to financial and economic issues, as well as management and contract issues.

Transformation of River Restoration Movement Network

A study on social network transformation of river restoration movement is very important as it is related to the network’s ability of adapting to various changes and a movement’s sustainability. This research aims to reveal the history of movement emergence, tactic, and strategy, process and procedure of social network establishment and social network transformation. An ethnographic approach was chosen by involving Komunitas Pemerti Kali Code (Code River Observer Community) as the main subject of current research. Data collection was conducted through live-in-society process for 2 months to conduct participant observation, in-depth interview and Focus Group Discussion. Data analysis was constructed using Mario Diani’s theory about social movement as a network. The result of research shows that the first factor is the emergence of problem and grievance about river contamination by rubbish and waste due to people’s poor literacy about river. The second one is movement strategy and tactic used in the form of structural and cultural approach to restore the river. The third is the process of creating social network based on shared idea, value, norm, collective identity, and interest related to the river. The fourth is social network experiencing transformation from spontaneity, institutionalization to autonomy phase as the attempt of adapting to and reconciling with the form of change to maintain the movement sustainability.
 Keywords: River Restoration Movement, Movement Strategy, Social Network Establishment, and Social Network Transformation

Microscopic aspects of γ softness in atomic nuclei

One of the main research themes in quantum many-body systems is the emergence of collective features from microscopic degrees of freedom. Using the microscopic approach of the triaxial projected shell model, the authors demonstrate that admixing a few quasiparticle excitations into the vacuum configuration with a fixed triaxiality parameter $\ensuremath{\gamma}$ provides a quantitative description of the shape fluctuations of the $\ensuremath{\gamma}$-soft nucleus ${}^{104}$Ru. The collective features are elucidated using the quadrupole shape invariant analysis, and also the staggering phase classification of the $\ensuremath{\gamma}$ band.

Uncovering culinary medicine research themes: Current status and future direction.

Background: Culinary medicine (CM), an emerging discipline, is a novel approach that focuses on the art of food and cooking to prevent or improve health outcomes among chronic patients suffering from lifestyle diseases. The concept originated in the USA, gaining interest from scholars in medicine, nutrition, nursing, and the gastronomic discipline. Notably, in the last five years, there has been exponential growth in CM literature. In this regard, this study sought to examine the growth, performance and distinct research themes of CM literature over time. Methods: To achieve the study's objectives, this study employs descriptive, performance and bibliometric analysis. The descriptive analysis was applied to examine the growth of the CM literature since its emergence. The performance analysis was used to identify the most influential journals, articles, and authors in the CM domain. The bibliographic coupling analysis was adopted to discover the various research themes of the CM knowledge base. Results: This study identifies three stages of literature development: Early stage, modest growth stage, and emerging stage. Further, the results indicate that most of the studies on CM had been conducted in developed countries. Our findings reveal a clear interest in integrating the CM curriculum into medical/nutrition education programs in recent years. Additionally, the study discovers four distinct main research themes: knowledge assessment, impact measurement, acceptance and efficacy, and implementation of CM. Conclusions: These findings are helpful for scholars in medicine, nutrition, nursing, and gastronomy as they provide an overview of CM's development and research focus.

Comprehensive performance of parallel feed MEE-MVC evaporation system

Abstract The mathematical model based on conservation of energy, mass and salinity is established to analyse the comprehensive performance of parallel feed multi-effect evaporation system with mechanical vapor compression (MEE-MVC) system. It is found that the efficiency of the MVC evaporation system gradually improves as the number of evaporator effect increases. However, the optimization trend of specific power consumption (SPC) and coefficient of performance (COP) are declining when the number of evaporator effect exceeds 3, which makes the marginal effect of the efforts made to improve the system gradually weakened. Then, the three-effect MVC evaporation system is taken as the main research subject to investigate comprehensive performance of the system. It was found that the SPC of the system increases with the increase of the total heat transfer temperature difference; on the other hand, the COP decreased significantly with the increase of the total heat transfer temperature difference. Furthermore, increasing the evaporation temperature in the last evaporator as well as compressor efficiency can optimize the energy efficiency of the system. In addition, the compressor efficiency has a greater influence on the SPC when the total heat transfer temperature difference is larger, whereas the compressor efficiency has a greater influence on the COP when the total heat transfer temperature difference is smaller.

Biprobes Blade Tip Timing Method for Frequency Identification Based on Active Aliasing Time-Delay Estimation and Dealiasing

Rotating blades are key turbomachinery components with high failure risk due to harsh working conditions. Thus, monitoring the running state of blades is urgently required. Blade tip timing (BTT) is regarded as a potential technology for blade vibration monitoring owing to its noncontact nature and low cost. However, severe undersampling and strict probe layout hinder the application of BTT. As a result of severe undersampling, aliasing and its suppression are the main research topics in BTT. However, in this article, a biprobes method for BTT based on the utilization of aliasing is proposed to identify the natural frequencies of blades. Active aliasing is used in this method to produce aliasing findings at various equivalent sampling frequencies, and the closed-form robust Chinese remainder theorem is used for dealiasing. Unlike the conventional multirate sampling systems for BTT that use a multiprobe configuration or varied speed, the suggested method utilizes varying delay durations to obtain varying equivalent sample frequencies. Furthermore, to ensure that active aliasing and dealiasing form a closed loop, an included angle coprime layout is proposed. Finally, the robustness and effectiveness of the proposed method are verified through numerical and experimental validation.
