The user's self-presentation in social networks and the problem of context collapse
Authors:   Dostoyevsky Omsk State University, Chesnokova Lesya V.
Published: June 2024

This article discusses the social problems of communication in social networks that provide a platform and tools for the formation of a virtual network identity. The features of the behavior of users of social networks and the tactics of their self-presentation when constructing a personal network profile are described. It is argued that in the process of social communication, people present different versions of themselves depending on their audience and adapting their own self-presentation to the perceived values and preferences of the interlocutors. The difficulties of online communication are described, where, unlike real interaction, the user does not have the opportunity to correlate his/ her behavior with the situational context and carry out differentiated self-presentation. The problems of blurring the boundaries of public and private in social networks and the loss of information privacy, which is a necessary condition for personal freedom and autonomy, are raised. It is argued that the disclosure of private information is an important component of maintaining social relations. It is noted that currently there is a transformation of cultural norms regulating the degree of openness-closeness and publicity-privacy. The concept of "context collapse" is introduced – a situation caused by the mixing of heterogeneous audiences with different social values, norms and expectations into one homogeneous group. The strategies are proposed to overcome the negative consequences of this situation: dividing the audience into several segments, self-censorship, forcing to avoid discussing controversial topics and adapting the user's language style, suggesting a reduction in language variability. The work was based on the methods of symbolic interactionism and I. Hoffman's theory of roles, which he used to build the dramatic theory of social interaction and self-presentation in social interaction.
“Digital” and sovereignty in modern Russian educational policy
Authors:   Saratov State University, Afanasyeva Kristina A.
Published: June 2024

The article presents an analysis of the contradiction that todaycharacterizes the stateinitiative for the transition of Russian education from the Bologna format to “sovereign” and “unique” functioning. This is a contradiction between the plans for accelerated digitalization of the educational sphere and, at the same time, for it to acquire certain qualities that are unique nowhere else in the modern world. Arguments are given in favor of the fact that attempts by subjects of Russian educational policy to give constructive meaning to the ideas of sovereignty of education in our country and its achievement of a state of uniqueness will face the objective need to sacrifice sovereignty and uniqueness for the sake of fulfilling the technical conditions of digitalization. The article predicts the expected risky consequences of such a conflict of meanings and goals in the ideology of planned educational reforms for state educational policy.

Chronic rhinosinusitis with nasal polyps is a heterogeneous disease characterized by local inflammation of the upper airways. Inflammation in chronic rhinosinusitis with nasal polyps is divided into 3 main endotypes with different pathophysiology and various forms of inflammation: T1, T2, and T3. Epithelial barrier dysfunction is a common feature in chronic rhinosinusitis induced by endotype-specific cytokines directly and indirectly. The sinonasal epithelium not only functions as a passive barrier but also is an active immunological organ with innate and adaptive components. Violation of the delicate balance of intercellular interactions in the sinonasal epithelium leads to the development of inflammation. The nasal polyp tissue contains numerous populations of immune cells that secrete many different cytokines and chemokines and interact with each other and with cells of the sinonasal epithelium. The most common is the T2 endotype, which is characterized by inflammation of the corresponding type. Inflammatory mediators such as cytokines, chemokines, and their receptors, are potential therapeutic targets for biologics (specific monoclonal antibodies). Several of these drugs have been clinically tested and are already being used in clinical practice. Further studies are aimed at detailing the pathogenetic mechanisms of nasal polyposis, studying the influence of genetic factors on the predisposition to the development of various endotypes, and creating new effective and safe biological preparations for various endotypes of nasal polyposis.

La diabetes es una alteración del metabolismo que afecta a millones de personas y aumenta el riesgo de muerte. Para controlar esta enfermedad, existen tratamientos farmacológicos y no farmacológicos. Dentro de estos últimos, se incluyen los alimentos funcionales, que son aquellos que tienen beneficios para la salud más allá de su valor nutricional. Estos alimentos pueden ayudar a regular los niveles de glucosa en sangre, que es el principal indicador de la diabetes. Para identificar qué alimentos funcionales son eficaces para la diabetes, se revisaron artículos científicos que evaluaron su efecto sobre la glucosa en ayunas, la glucosa postprandial y la hemoglobina glicosilada (HbA1c). Se encontró que el cacao, café, canela, ajo, guayaba, jengibre, arándanos y cúrcuma son alimentos funcionales que reducen estos parámetros, siendo la guayaba el más efectivo para bajar la glucosa postprandial.

Abstract. The active development of the scientific world leads to an increase in the amount of neces-sary information for the successful study of any disciplines. New innovative technologies aimed at more effective use of individual characteristics of students are required for a better implementation of pedagogical activities. In this research, as one of the individual characteristics of students we consider students’ thinking styles according to A. Harrison and R. Bramson classification. Based on the presented thinking styles, we analyze effectiveness of using visualizing learning tools, namely: presentations, excerpts from feature films or documentaries, materials from video hosting sites and graphs. We analyze results obtained in the study of students’ perception of two groups of information through visualization, depending on their thinking style. The obtained results are applicable in pedagogical practice as an auxiliary tool, especially when teaching groups of up to 20 people or for more effective use of several visualization tools in groups of any size, taking into account the existing ratio of students with different styles of thinking, regardless of the group size.

Abstract. To identify the features of psychosocial adaptation of combatants in peacetime conditions depending on the profile of their professional activity, we surveyed 105 participants of combat actions, with an average age of 33.3 ± 3.9 years and a service experience of 4.7 ± 1.8 years. All surveyed combatants were divided into two groups based on their professional characteristics: the 1st group consisted of 50 employees of the Ministry of Internal Affairs of Russia, performing tasks related to maintaining order and public safety in front-line territories, and the 2nd group comprised 55 servicemen of the National Guard of Russia who directly participated in combat actions. Questionnaires and psychological tests were conducted using the Trauma Screening Questionnaire and the Buss–Durkee Hostility Inventory. Statistical analysis of the data was performed using SPSS 20 software, and Pearson’s chi-squared test, Student’s t-test, and Pearson's correlation analysis were applied to determine intergroup differences. There are certain differences in the features of psychosocial adaptation between employees of the Ministry of Internal Affairs of Russia and servicemen of the National Guard of Russia: the use of the Internet to relieve emotional tension, reactions to alcohol, and the presence of rigidity in character. At the same time, interpersonal communication and psychoemotional state did not differ among combatants performing combat tasks and ensuring public order in front-line territories, which may indicate a similar influence of traumatic military stress on the psychological state of participants of both groups, regardless of professional activity.

Abstract. We consider the issue of eating disorders in adolescents and search for personality traits that determine the disorder formation. The research purpose is to identify eating disorders and mental rigidity in adolescents aged 13–17 years, as well as to establish the correlation nature. The used methods are: Eating Disorder Inventory, Tomsk Rigidity Questionnaire. Adolescent girls (13–17 years old) participated in the study conducted on the basis of the Secondary schools no. 31 and 33 in Tambov. 2 groups were formed: experimental – 27 people (adolescents with signs of eating disorders) and control – 26 people (adolescents with normal eating behavior). It was found that the distribution of average values on the scales of mental rigidity in adolescents with eating disorders was significantly higher (Mann–Whitney U test) than in the subjects of the control group. This fact testifies to such personality traits of adolescents with impaired eating behavior as: getting stuck in established mental set, stereotypes; inability to change one’s mind if necessary; negative emotional reaction in the form of fear to possible objectively necessary changes, difficulties in accepting new things and the need to change oneself. Correlation analysis using Spearman’s criterion revealed a positive, statistically significant correlation in the indicators “Bulimia”, “Striving for thinness” of Eating Disorder Inventory and the scales of Tomsk Rigidity Questionnaire. It has been proven that eating disorders positively correlate with a high level of mental rigidity. The practical significance of the study lies in the fact that it allows to outline ways to prevent and correct eating disorders in adolescents. Psychological work should be aimed at the formation of plasticity of thinking and increasing the level of emotional and behavioral flexibility. Working with cognitive attitudes and rigid beliefs about weight, body, figure and appearance, forming a healthy attitude to food, analytical acceptance of information, will reduce the risk of the spread of eating disorders among adolescents.

Published: June 2024

Abstract. Based on the analysis of psychological and pedagogical research we consider the features of pedagogical support for the self-realization of foreign students in a Russian university such as: dependence of the humanitarian strategy of education and process of personal and professional development, implementation of adaptation functions, complementarity of psychological characteristics of foreign students, integration of different areas of pedagogical support, etc. As a result of the research, developed theoretical model of pedagogical support for self-realization of foreign students in a Russian university includes five main blocks. Concept and target block contains the goal of achieving a high level of self-realization of foreign students in a Russian university, methodological approaches – systemic, axiological, subjective-activity, reflective and environmental, principles: initiative and activity, personalization, continuity and tradition, consistency and progression of intercultural interaction. Structural and content block includes the definition of the concept of “self-realization of foreign students in a Russian university” and the components of self-realization: value, target, resource and conative. Organizational and activity block contains a Program of pedagogical support for self-realization of foreign students, as well as technologies, forms, methods of its implementation. Determinant block consists of factors (need of foreign students for personal development; value-semantic attitude of foreign students to self-realization; satisfaction with interpersonal relationships in a new socio-cultural environment) and conditions (ensuring social integration; maintaining a multicultural educational environment of the university; actualization of subject-subject relations of all participants in the educational process) that determine the process of self-realization of foreign students. Efficient and diagnostic block consists of criteria for self-realization: axiological, efficient, competence, behavioral and levels of its development: unproductive, productive, productive at a medium level, productive at a high level.

Published: June 2024

Introduction: Parental empowerment in monitoring adolescents plays a crucial role in preventing health-risk behaviors. This research aimed to develop a model of parental empowerment against the prevention of health risk behavior (PE-HRB) in adolescents based on the theory of health promotion model.
Methods: The research design used was an explanative survey method. The research population was parents who have adolescent children in East Java and able to access online questionnaires. Consecutive sampling obtained a large sample of 704 respondents from July - September 2020. Questionnaires were distributed online using the online Zoho platform and distributed to parents. The data analysis used a smart PLS (Partial Least Squares) statistical test with significance level T>1.96.
Results: Personal factors positively and significantly influenced cognition and affect (T=2.82;p=0.005). Cognition and affection variables influence on parental empowerment (T=5.19; p=<.001). Cognition and affection have no effect on preventive behavior (T=1.49; p=.135). Parental empowerment is an important point in shaping preventive behavior.
Conclusions: Empowerment is a factor that significantly affects the formation of parental behavior without going through commitment variables. Parental involvement in adolescents’ academic and personal lives is an important aspect to prevent health-risk behavior in adolescents. Cognition and affection variables cannot directly form preventive behavior but must go through parental empowerment pathways to form preventive behavior. Parental empowerment has no effect on commitment, but commitment affects prevention behavior. Empowering parents is a topic that can be used as material in health education in primary health services.

Published: June 2024

Introduction: Restless legs syndrome (RLS) presents as a sleep-related issue in individuals with chronic kidney disease (CKD), contributing to heightened sleep disturbances and diminished quality of life. Consequently, this meta-analysis was conducted to assess the prevalence of RLS among CKD patients.
Methods: A comprehensive search for articles published between inception and September 2023 was conducted across CINAHL, Cochrane, Embase, Ovid-MEDLINE, PubMed, Scopus, and Web of Science databases. A Comprehensive Meta-Analysis (CMA) software version 3.0 with random effects models was used for pooled prevalence and prediction interval analysis. Heterogeneity was assessed using the I2 test and Cochran's Q-statistic. The quality of the studies was evaluated using Hoy's risk of bias. Additionally, moderator analyses were performed to investigate variations in the prevalence estimates among the included studies.
Results: A total of 97 studies were included in this meta-analysis with 315,875 participants. The pooled prevalence of RLS among CKD patients was 25% (95%CI: 20% to 32%). In terms of the demographic breakdown, the prevalence of RLS was nearly comparable in adults and children/adolescents at 25% and 21%, respectively. The prediction interval indicated a potential future RLS prevalence ranging from 1% to 88%. Notably, iron and phosphorus levels emerged as significant moderating factors influencing the prevalence of RLS.
Conclusions: Roughly 25% of individuals with chronic kidney disease (CKD) encounter restless legs syndrome (RLS). It is imperative to foster collaboration among healthcare professionals to facilitate proactive management and early assessment of RLS, thereby enhancing the overall quality of life for CKD patients.
A Study on the Image of Shamans from the Perspective of the Scholar-gentry(士大夫)
Authors:   The Research Of The Korean Classic, Lee Ju-young
Published: June 2024

This article examines the portrayal of shamans through the perspective of the scholar-gentry(士大夫) class as reflected in various records, such as Pilgi(筆記) and Yadam(野談), and explores the significance of these portrayals. From the late 13th century, shamans were subjects of rejection and criticism by the scholar-gentry, and after the founding of the Joseon Dynasty, they were perceived as antagonists disrupting the order of Confucian society. Shamans were negatively depicted, labeled as “wicked shamans” or “fake shamans.” The literati aimed to emphasize the legitimacy of rejecting shamans through these depictions. The literati focused their criticism on shamans who deceived people and gained undue benefits by exploiting superstitions about spirits. Male shamans dressed in women's clothing were recognized as the primary image of the “wicked shaman.” On the other hand, shamans were unique beings capable of communicating with spirits or ghosts through possession(降神/憑依). Although the scholar-gentry rejected shamans, they were very interested in their spiritual abilities. This is connected to verifying the authenticity of “spiritual shamans” and “genuine shamans”. As the Joseon Dynasty progressed, the scholar-gentry increasingly acknowledged the spiritual power of shamans through their experiences and observations of possession phenomena. Consequently, they began to view shamans and shamanistic practices more positively compared to earlier periods. Narratives from the late Joseon period include acceptance of shamanistic phenomena and rituals, and shamanistic practices often served to complement or even replace Confucian rituals. Shamans were depicted as marginalized figures, yet they secured their position by serving as spiritual intermediaries for the common people. This dual perspective on shamans reflects the contradiction between the literati's ideals and the reality of their perception. The scholar-gentry show a more flexible and reserved attitude toward shamans than before, expecting an interest in the unknown world, experiences with them, and solving practical problems through shamans. That is, shamans were portrayed as beings who were excluded from the Confucian society, but simultaneously, they were seen as entities filling the gaps within that society, thus maintaining their vitality.
A Study on the Social Critical Consciousness and the Way of Resolution of Social Conflict in

 was written by Lee, Ok, a writer in the late Joseon Dynasty. It deals with a fraud case that Jinsa Seong, Hui-ryong in Sangju went through.
However, the social critical consciousness of  draws attention to the serious economic imbalance in late Joseon society and class conflicts between the yangban and the common people, the rich and the poor through the appearance of refugees caused by famine, not just in fraud cases.
In particular, the essence of  lies in its approach to resolving societal conflicts. The purpose of this study is to the perspective on and proposed solutions to conflict within  with a particular focus on the relationship between its two protagonists, Seong, Hui-ryong and a beggar. The narrator argues that Seong, Hui-ryong's self-refinement[謹身] was instrumental in resolving the conflict, exploring the broader connotation of such self-refinement.
Within  the ‘door’ represents both the starting point of the incident and is the boundary that separates the space between Seong, Hui-ryong and the beggar. The space in  is divided into a rich inner space inside the door where the rich reside along the boundary of the door, and an outer space outside the door of the refugees who become beggars and wander after losing their homes. Therefore, it is recognized that the ‘door’ should be closed and protected for the rich, and open for the beggars.
Nonetheless, the door also serves as a conduit that connects and associates the two worlds inside and outside. By opening the door and recognizing the beggar as another subject, Seong, Hui-ryong facilitates conflict resolution through dialogue. Face-to-face communication fosters empathy centered on the other, paving the way for conflict resolution. In other words, ‘face-to-face’ is to recognize the other outside the door as another subject like me. ‘Self-refinement’ encompasses not only self-cultivation but also placing others at the core of one's concern.
The possibility of resolving such conflicts offers insights into bridging the gap between the reality of laws and legal sentiments. In a space governed by legal standards, endless opposition between legality and illegality persists due to a binary perception that merely seeks a stronger law to satisfy one's legal sentiments.
Recognizing the other as a mutual subject through communication allows for attentiveness to one's conscience, unveiling hidden truth, and enabling forgiveness through empathy. This is the way to resolve conflict suggested by . Although it is a short work, what  has achieved is truly great.
Strategies for Educational Use of Folktales for Mutual Understanding and Development between International and Korean Students
Authors:   The Research Of The Korean Classic, Han Sae-hae
Published: June 2024

This study notes that the use of folktales, especially among classical literature, can be used as an interesting course to converge and accept both domestic and foreign learners at the qualitative and academic level. As the influx of international students in domestic universities increases, the number of lectures taken by international students and Korean students is also increasing. However, in the field of universities, there is an inevitable educational gap between international students and Korean students. In this situation, it is meaningful that the educational use of folktales maximizes the participation of the members and enables mutual communication. The text used at this time can be selected not only from Korea but also from other countries/mother countries, and the student actively learns the story through the process of ‘reading-listeningwriting-speaking’ with the instructor. It is judged that such a learning plan can confirm the universality of the old story for both international and domestic students and expand it to an opportunity to understand the traditionality and uniqueness of Korea at the same time. Accordingly, by introducing specific lecture plans and related materials, and analyzing resentations of learners submitted as final results, we will discuss the future-oriented development direction that this folktales education implies.
The Practice of Creative Content Based on Classical Literature: Focusing on Case Analysis of Assignments of Department of Media Storytelling
Authors:   The Research Of The Korean Classic, Shin Yun-kyung
Published: June 2024

This article analyzes the assignments submitted by students in the Media Storytelling Department to the  course and examines students' perceptions and applications of classical literature.
The results of the analysis of students' assignments are as follows. First, there is no hesitation in borrowing, expanding, revising, or mash-up. There is a strong tendency to cut out some of the narratives necessary for the content without hesitation and insert them into the person-centered narrative he planned. Second, they show interest in the characteristics of the characters and the person's narrative. From a macroscopic point of view, they show the characteristic of paying more attention to small narratives centered on characters rather than dealing with the entire narrative of the classical literature. Third, we try a thematic approach to bring the social problems that are prevalent around us into their works. However, it is unfortunate that there are many cases where the planned medium is converted into web novels after feeling pressure to implement the content as a visual image.
Students play two roles: learners of classical literature and creators who produce content at the same time. Classical literature dispels the preconceived notion that it is difficult and bizarre, and learns the characteristics of media and trans storytelling in the process of converting it back to various media, feeling the joy of reading classics from the realization that it is full of diverse and novel stories and characters. Instructors should encourage the diverse use of media, but guide students to recognize classical literature as valuable materials to obtain creative materials.

Abstract. Introduction. Lung function disorders in patients with ankylosing spondylitis can be caused both by the disease itself and the side effect of the treatment. Aim. The aim was to investigate the lung function in patients with ankylosing spondylitis and analyze its dynamics after COVID-19 on the example of clinical case. Material and methods. 29 patients were enrolled in the study. Spirometry, body plethysmography, diffusion test was performed. In 1 patient the dynamics of parameters was analysed after COVID-19. Statistical analyses were performed using SPSS 23.0. Quantitative data with a normal distribution were presented as the mean and standard deviation (m±σ). The data with different type of distribution were presented as the median and interquartile range (Me [Q1 ; Q3 ]). The differences between quantitative parameters were assessed by student’s t-test for data with normal distribution and by the Wilcoxon test for data with different distribution. To assess the differences between qualitative parameters the Fisher’s exact test was used. A value of p<0,05 was considered to be statistically significant. Results and discussion. A retrospective cross-sectional study was performed. The predicted values of the European Community for Steel and Coal 1993 and the Global Lung function Initiative were used in the analysis. On average, no ventilation disorders were detected in the group. However, 7 (24%) patients had airway obstruction. Restriction and impaired lung diffusion capacity were detected in 3 (10%) and 12 (41%) patients using European Community for Steel and Coal 1993 predicted values system and in 2 (7%) and 6 (21%) patients using the Global Lung function Initiative predicted values system respectively. The differences were statistically significant. In clinical case, the previously established lung function disorders became more pronounced after COVID-19: ventilation capacity, total lung capacity, diffusion lung capacity decreased by 50%, 35%, 38% respectively. Conclusion. Lung function tests should be included in the examination plan of patients with ankylosing spondylitis. Patients with ankylosing spondylitis may have a more severe course of COVID-19. The system of the predicted values used should be presented in the medical report.

Published: June 2024

Objectives: The present study investigates the association between the health-related quality of life of Korean adult women and their socio-demographics, health behavior, and psychological characteristics. Methods: The analysis was carried out using the 8th Korea National Health and Nutrition Examination Survey data (KNHNES) in the second year (2020), and the subjects consisted of 2,181 adult women between the ages of 19-64. A multivariate linear regression analysis was performed, employing three models to identify factors related to health-related quality of life as the dependent variable. In Model 1, socio-demographic characteristics were considered. While Model 2 includes both socio-demographics and health behavior characteristics. In Model 3, psychological characteristics as well as socio-demographic and health behavior characteristics were considered. Results: The health-related quality of life of adult women in late adulthood, post-menopause, low household income, and poor subjective health status were found to be low in the analysis of socio-demographic characteristics. For the health behavior characteristics, the health-related quality of life showed significant differences with respect to smoking, drinking, sleeping, and physical activity but these variables were not identified as the affecting factors. For the psychological characteristics, depression and perceived stress were found to be factors lowering the health-related quality of life. Conclusions: To enhance the health-related quality of life of adult women, prevention and proper management of depression and stress for those with poor health behavior are needed with special care and support for post-menopause women with low household income and poor subjective health status.

Authors: Torres Montes de Oca Carlos Alberto , Rosas Valencia José Eduardo , Pérez Jarquín Oswaldo Aldair
Published: June 2024

Many historic buildings have symmetry in their geometric configuration. The objective of this research is to denote the application of numerical-vector succession in the structural analysis of historical masonry buildings, with arches and symmetrical systems, including mathematical processes in ancient graphic analysis, emphasizing the importance of loads in the structural stability. We based the analysis on three fundamental stages: recognition of the construction system of the heritage object, geometric discretization of the system and vector analysis under different physical considerations. Hence, the thrust lines are affected by the loads, boundary conditions and history of structural behaviour. Numerical and computational tools offer faster and more accurate graphic analysis processes.

BESS Revolutionizes Renewable Stability in Indonesia
Authors: Zuhri Muhamad Saifudin , Jamaluddin Jamaluddin , Ayuni Shazana Dhiya , Anshory Izza
Published: June 2024

This study examines the integration of Battery Energy Storage Systems (BESS) with Solar Power Plants (PLTS) to enhance electrical grid stability in Indonesia, where 90% of electricity is from fossil fuels. The intermittent nature of PLTS often destabilizes the network, causing frequency hunting or blackouts. Using Etap 12.6 software, simulations showed that adding BESS to hybrid PLTS-PLTD systems significantly mitigates these issues. For instance, a 50% drop in PLTS power without BESS required a 55% increase in PLTD power, but with BESS, this increase was only 34%. Thus, BESS is crucial for stabilizing renewable energy integration and supporting Indonesia’s Net-Zero Emissions goal.

Heavy metals represent a serious source of water and soil contamination, mainly due to their non-biodegradable nature. Their bioaccumulation occurs in plants and other trophic levels, including animals, consequently affecting humans and causing various side effects. Phytoremediation offers a biological, cost-effective, and environmentally friendly cleaning solution, utilizing plants to remove contaminants from soil and water. This study aims to establish the chemical composition of Pontederia parviflora and Salvinia auriculata using liquid chromatography and evaluate the role of their secondary metabolites in passive phytoremediation by these plants. Although the results are not aligned with the initial hypothesis of metal removal from the liquid medium (sequestration and chelation of metals), the amount of metal removed still represents a positive outlook for technique enhancement. Furthermore, this research challenges the notion presented in the literature, as secondary metabolites were considered contaminant sequesters. The removal of these metabolites from the biomass of these macrophytes did not significantly impact their phytoremediation performance.
Research on Risk Factors Identification and Action Pathways of Mangrove Carbon Sink Projects from the Perspective of Supply Entities
Authors: He Yixiong , Wang Yanwei , Xie Sumei
Published: June 2024

Mangrove carbon sink is one of important and strategic ways of addressing the problem of carbon emissions, and mangrove carbon sink projects are important carriers to realize the value of mangrove carbon sink. There are various risks involved in the process of developing mangrove carbon sink projects as they will have a significant impact on the successful development of these projects. From the perspective of the supply entities, this article divides the entire life cycle of mangrove carbon sink projects into five stages: (1) decision stage, (2) design stage, (3) construction stage, (4) verification and filing stage, and (5) operation and maintenance stage. With the goal of achieving project success a risk measurement and evaluation model is hereby established, and the impact paths and coefficients of 61 risk factors in the entire life cycle of mangrove carbon sink projects are obtained. The research results indicate that: (a) different life cycle stages exhibit different risk impact paths and coefficients, with the design stage and the operation and maintenance stage bearing the greatest impact of risk in the project; (b) for mangrove carbon sink projects, policy risks, technical risks, and market risks are the three major types of risks that require special attention; (c) about 1/4 of all the risk factors belong to the category of first level risk. These research results can provide a theoretical basis for the effective implementation of risk management plans for mangrove carbon sink projects, so as to ensure greater project effectiveness, promote the development of mangrove carbon sink projects, and ultimately contribute to the realization of the goal of carbon neutrality.

Background
The unprecedented scientific response to the SARS-Cov-2 pandemic in 2020 required the rapid development and activation of extensive clinical trial networks to study vaccines and therapeutics. The COVID-19 Prevention Network (CoVPN) coordinated hundreds of sites conducting phase 2 and 3 clinical trials of vaccines and antibody therapeutics. To facilitate these clinical trials, the CoVPN Volunteer Screening Registry (VSR) was created to collect volunteer information at scale, identify volunteers at risk of COVID-19 who met enrollment criteria, distribute candidates across clinical trial sites, and enable monitoring of volunteering and enrollment progress.
Methods
We developed a secure database to support three primary web-based interfaces: a national volunteer questionnaire intake form, a clinical trial site portal, and an Administrative Portal. The Site Portal supported filters based on volunteer attributes, visual analytics, enrollment status tracking, geographic search, and clinical risk prediction. The Administrative Portal supported oversight and development with pre-specified reports aggregated by geography, trial, and trial site; charts of volunteer rates over time; volunteer risk score calculation; and dynamic, user-defined reports.
Findings
Over 650,000 volunteers joined the VSR, and 1094 users were trained to utilize the system. The VSR played a key role in recruitment for the Moderna, Oxford-AstraZeneca, Janssen, and Novavax vaccine clinical trials, provided support to the Pfizer and Sanofi vaccine and prophylactic antibody clinical trials, and enhanced the diversity of trial participants. Clinical trial sites selected 166,729 volunteer records for follow-up screening, and of these 47·7% represented groups prioritized for increased enrollment. Despite the unprecedented urgency of its development, the system maintained 99·99% uptime.
Interpretation
The success of the VSR demonstrates that information tools can be rapidly yet safely developed through a public-private partnership and integrated into a distributed and accelerated clinical trial setting. We further summarize the requirements, design, and development of the system, and discuss lessons learned for future pandemic preparedness.
