Published: February 2024

The integration of reproductive health into community development and social work represents a critical endeavor in promoting holistic well-being and empowerment at the grassroots level. This review highlights strategies for effective engagement and empowerment within this framework. Firstly, a comprehensive understanding of the community's socio-cultural context is imperative. Cultural sensitivity and competence enable practitioners to navigate sensitive reproductive health issues within diverse communities. Utilizing ethnographic approaches and community-based participatory research facilitates the identification of local beliefs, practices, and barriers related to reproductive health. Secondly, building collaborative partnerships with key stakeholders is essential. Engaging local leaders, healthcare providers, educators, and religious institutions fosters buy-in and facilitates the development of culturally relevant interventions. These partnerships enhance the reach and sustainability of reproductive health initiatives by leveraging existing community resources and networks. Thirdly, incorporating a rights-based approach is fundamental for empowering individuals and communities. By promoting reproductive rights, including access to comprehensive sexuality education, contraception, and safe abortion services, practitioners empower individuals to make informed choices about their sexual and reproductive health. Moreover, advocating for gender equality and addressing harmful gender norms and practices are integral components of fostering reproductive autonomy and empowerment. Furthermore, capacity-building efforts play a pivotal role in enhancing community resilience and sustainability. Equipping community members with knowledge and skills in reproductive health education, advocacy, and service provision enables them to take ownership of their health and drive sustainable change within their communities. Finally, leveraging innovative technologies and communication channels enhances the accessibility and effectiveness of reproductive health interventions. Mobile health applications, telemedicine, and social media platforms provide avenues for disseminating information, delivering services, and promoting dialogue on reproductive health issues. Integrating reproductive health into community development and social work requires a multi-faceted approach that prioritizes cultural competence, collaboration, rights-based empowerment, capacity-building, and innovation. By employing these strategies, practitioners can effectively engage communities and empower individuals to achieve optimal reproductive health outcomes and overall well-being.

Published: February 2024

The global push towards renewable energy sources as a response to climate change has led to an increasing overlap between renewable energy projects and critical wildlife habitats. This review explores the potential conflicts and synergies between renewable energy policies and wildlife conservation efforts. As nations strive to transition from fossil fuels to sustainable alternatives, the unintended consequences on biodiversity and ecosystems demand careful consideration. The analysis begins by examining the conflicts arising from the development of renewable energy infrastructure, such as wind and solar farms, in ecologically sensitive areas. These conflicts include habitat disruption, altered migration patterns, and the direct threat to endangered species. The paper also delves into the social implications of renewable energy projects, such as displacement of indigenous communities and the disruption of traditional land use. However, the review doesn't solely focus on conflicts but also explores coexistence strategies that can mitigate the adverse impacts of renewable energy development on wildlife. It highlights the importance of strategic project siting, wildlife-friendly design considerations, and effective mitigation measures. Additionally, the paper discusses the potential for incorporating ecological restoration efforts within renewable energy projects to enhance habitat quality and support biodiversity. Furthermore, the review addresses the role of policy frameworks in promoting sustainable coexistence between renewable energy development and wildlife conservation. It evaluates existing policies and proposes recommendations to strike a balance between the imperative of clean energy and the preservation of biodiversity. This review synthesizes current knowledge on the complex interplay between renewable energy policies and wildlife conservation, offering insights into potential conflicts and proposing coexistence strategies. Balancing the dual objectives of mitigating climate change and preserving biodiversity requires a nuanced understanding of the ecological, social, and policy dimensions involved. The findings presented contribute to a holistic approach that aims to harmonize renewable energy development and wildlife conservation for a sustainable future.
Exam as an instrument for student-active learning in STEM education – An example from a reliability analysis course
Authors: Selvik Jon T , Abrahamsen Eirik B
Published: February 2024

Exams have a powerful role in higher education typically in the form of summative assessment, where the goal is to evaluate student learning at the end of the course; to test whether the students have achieved the learning objectives. Beyond representing a final activity in the course, exams have a role in giving students exam-relevant problems to solve, and to communicate a set of standards. It can be argued that this problem-solving activity contributes to learning and will make the students better equipped to perform well on the final exam. From the teacher’s perspective, the designing of exams represents a task creating specific awareness to the course content and student capabilities. In this paper, focus is on student activity and in-depth learning, where we investigate a potential to use exams more actively in learning activities prior to the summative assessment. A way suggested in this paper and tested for a reliability analysis (probability and statistics oriented) course, is to have the students design on their own an exam set with solutions, preferably in groups. The students have access to supervision and are given feedback on their product. There is a rationale that this activity may add motivation, and results indicate a positive learning benefit from the initiative, which is also supported by feedback collected from the students in the course evaluation. Main feedback being that it makes them see problems from different perspectives and taking a more active role. Besides, the format to work together with other students on solving a low-stake but value-adding task without direct influence on their grade was appreciated. The way allows for creative thinking and reflection. It extends the traditional use of exams and represents a way in line with problem-based learning thinking.
Influence of Thinking Style on the Critical Thinking Skills and Creativity in Mathematics
Authors: Perez Lemuel , Andrade Rose
Published: February 2024

Two of the key talents that students need to possess in the twenty-first century are the ability to think critically and creatively, both of which can be nurtured through mathematics training. Teachers should take into account the various ways that each student thinks when using pedagogical strategies to help students develop their critical and creative thinking abilities in mathematics. Thus, the main goal of the study was to determine whether there were any significant differences in the critical thinking and creativity abilities in mathematics among the various thinking styles of Grade 10 students in a national high school in the Philippines. In order to compare the differences between the critical thinking skills and creativity of sixty respondents in mathematics depending on their thinking styles—inchworm and grasshopper—a comparative descriptive research design was used in the study. The results showed a significant difference in the critical thinking skills in mathematics as to interpreting information component only of critical thinking skills. Furthermore, thinking style is not a determinant in students’ mathematical creativity due to non-existence of significant difference. The study recommends that teachers consider students’ thinking styles when developing instructional materials and strategizing their instruction because this helps students interpret information and decide whether the evidence and conclusions obtained from mathematical problems can be generalized. To confirm the study’s conclusions, a similar study with a high number of respondents for each thinking style is recommended.

Published: February 2024

Purpose: The main objective of this study is to develop a substance that can enhance the absorption of radiation therapy for head and neck cancer and protect the surrounding tissues of the tumor during radiotherapy.

Materials and Methods: The dimensions of the specimen are 40 mm x 55 mm in length and width, with a thickness of 6 mm based on Iraqi population studies. The sample was composed of four groups, A, B, C, and D. Each group was exposed to two different types of energy, 4 MEV, and 9 MEV, by the VARIANI X2300 radiation machine.

Results: The amount of radiation penetration was measured and statistically analyzed using Levene’s and two-way ANOVA tests to determine the differences and identify the best materials. The data from this study show a highly significant difference (p-value < 0.001) in radiation penetration between all groups.

Conclusion: The stent made with a combination of cold-cure acrylic and tungsten alloy has the lowest radiation penetration at 4 MEV and 9 MEV energy levels, making it the best material stent for protecting healthy tissues against radiation. On the other hand, stents made solely with cold-cure acrylic offer poor radiation protection.

Cybersecurity Vulnerabilities in Healthcare: A Threat to Patient Security
Authors: Triplett William J.
Published: February 2024

Healthcare information systems hold significant importance; hence, their cybersecurity is crucial. Exposed networks make it easy for cybercriminals to launch cyberattacks and access healthcare data. Thus, concerns regarding cybersecurity and its link to healthcare privacy, confidential data, and medical devices are growing. Therefore, cybersecurity vulnerabilities in healthcare and patient security are significant issues. Healthcare information systems comprise correlated networks and play a vital role in treating and saving patients. However, advanced circulated ransomware attacks on hospitals prevent access to electronic health records for providing appropriate patient care, thus forcing doctors to turn to other facilities. These cyberattacks can leak patient data, and regaining control of information systems and patient data is highly expensive, thus resulting in extensive monetary losses. Cyberattacks aimed toward electronic medical records, information technology systems, and medical devices have corrupted the best systems across clinics and small offices with physicians, as well as merged health systems. There is an urgency to address cybersecurity vulnerabilities in healthcare; however, opinions differ regarding suitable measures for safeguarding patient data and ensuring infrastructural security. We aimed to reconcile these diverging hypotheses and provide an understanding of the current landscape and directions for further improvements by reviewing several studies on healthcare cybersecurity. We also interviewed healthcare professionals, cybersecurity experts, and administrators and distributed a survey questionnaire to healthcare organizations to gather quantitative data on existing cybersecurity measures and vulnerabilities. Our analyses show that healthcare organizations are vulnerable to a variety of threats, cyberattacks disrupt the health sector, cybersecurity vulnerabilities impact patient security, and implementations of cybersecurity measures are inconsistent across organizations. Owing to the sophisticated nature of cyberattacks, the healthcare industry must prioritize cybersecurity and provide the funding required to develop critical systems for safeguarding patients and their data. The study's findings underscore the need for standardized cybersecurity practices in healthcare to address inconsistencies in measures across organizations. Adequate and ongoing investment in cybersecurity infrastructure is imperative to counter increasingly sophisticated cyberattacks. Additionally, protecting patient data and maintaining trust within the healthcare sector are ethical imperatives that should guide industry actions. By embracing these implications, the healthcare industry can enhance patient security, financial stability, and ethical integrity.

On the Change of the Legal Standards for “Public Body” in the WTO Subsidy and Countervailing Agreement
Authors: Song Ziyan
Published: February 2024

The WTO Agreement on Subsidies and Countervailing Measures (ASCM) defines a subsidy as having four elements, of which the "public body determination criterion" is designed to ascertain whether a state-owned enterprise (SOE) constitutes the subject of a subsidy, and is an important prerequisite for confirming the establishment of a subsidy. However, neither the WTO nor other international organizations have clearly specified this concept. In DS437, one of the points of contention was the criteria for determining a "public body". On 16 June 2019, the WTO published the Appellate Body (AB)'s report, whose explanation of the "public body" determination substantially rejects China's argument and to some extent supports U.S. claim. This ruling shows that the risk of China's SOEs being recognized as public bodies will continue to exist, leaving room for other countries' countervailing agencies to investigate. In this regard, China should further promote the "governmental authority Theory", while continuing to deepen the mixed-ownership reform of SOEs, so as to get out of the predicament of SOEs participating in international competition.
Research on China's Chip Industry Policies in the Context of the China-US Trade War
Authors: Wang Guanghui
Published: February 2024

China and the US have always been important trading partners, but the huge unilateral trade deficit of the US has led the Trump administration to launch a "trade war" against China in an attempt to reverse the trade deficit through tariffs. In the Sino-US trade war, the US has launched a "301" investigation against Chinese companies, targeting China's high-tech sector. The United States has added Huawei, SMIC and other leading domestic chip companies to its list of entities, which has seriously hindered the development of China's chip industry. Before the Sino-US trade war broke out, China could import high-end chips from the US, but after the trade war, the US cut off the supply of high-end chips to China. Chip is the foundation of semiconductor technology enterprises and the strategic basis of national development. But China is not deeply involved in this strategic industry and faces a bottleneck in key technologies.
Inception meets Swin Transformer: A Novel Approach for Metal Defect Recognition
Authors: Tang Donglin , Zhao Yunliang
Published: February 2024

The detection of metal defects with high precision and efficiency is a significant challenge in modern industry. Existing machine learning methods for recognizing common metal surface defects heavily rely on expert knowledge for manual feature extraction. Conventional deep learning methods face challenges in capturing global feature information from defect images or defect detection signals.To address this issue, we proposed a metal defect recognition method based on an Inception-fused Swin Transformer model. The method combines the adaptive local feature extraction capability of the Inception structure with the advantage of the Swin Transformer in capturing global feature information from defect signals. Additionally, it utilizes the Channel-Coordinate Attention module (CoordAttention) to highlight important feature channels. Experimental results demonstrate the effectiveness of the proposed method on the Ultrasonic Defect Grayscale Image dataset (ULFSL-DET) and the publicly available Image-based Metal Defect dataset (NEU-CLS), achieving recognition accuracies of 98.1% and 99.8%, respectively. The method exhibits high effectiveness in recognizing metal defect signals in grayscale images, and it demonstrates strong generality for image-based metal defect recognition.
Brief Discussion on Non-destructive Testing Methods for Pressure Pipeline Defects
Authors: Yang Xiaonan
Published: February 2024

With the development of China's oil and gas energy industry, the specifications of pressure pipelines for oil and gas transport are also becoming higher and higher, such as large caliber, ultra-thin wall, high pressure and other requirements, and the defects of pressure pipelines are becoming increasingly prominent. Due to the use of the environment, the material of the pipeline and other reasons, the pressure pipeline will produce a variety of defects in use. Non-destructive testing should be carried out on the defects caused by the pipeline in a timely manner, and according to the test results, defects should be graded according to the corresponding testing standards, so as to prevent the in-service pipeline from containing excessive defects and prevent pipeline breakage or explosion accidents.
Target Research Based on BLIP Model
Authors: Song Haisheng , Song Yingdong
Published: February 2024

Visual language pretraining (VLP) has made significant progress in improving performance on multiple visual language tasks. However, most current pre-trained models are either good at comprehension tasks or focus on generative tasks. Furthermore, performance improvements often rely primarily on expanding datasets generated by collecting noisy image-text pairs from networks that are suboptimal sources of supervision. In this paper, we propose a new VLP framework, namely BLIP, which can be flexibly applied to visual language understanding and generation tasks. BLIP effectively utilizes noisy network data by guiding subtitles. Its subtitle generator produces synthetic subtitles, and filters are used to clean these noisy subtitles. In order to meet the practical needs of existing search engines to improve retrieval speed and retrieval accuracy, this paper proposes an improved method based on the BLIP algorithm. We migrated the image and text retrieval strategy of the BLIP algorithm from itc comparison to itm comparison, and improved the model's positive and negative sample discrimination ability by using the hard-sample strategy. We further improve the retrieval accuracy of the model.
The Average Chinese Family How to Build an Optimal Investment Portfolio in an Uncertain Market Environment
Authors: Jin Yiting
Published: February 2024

Classical portfolio theory suggests that the maximum expected return for a given level of risk can be achieved through an appropriate allocation between different asset classes. However, in reality, markets are not always fully efficient and there are factors such as market failures and speculative behaviour, which may result in investors not always achieving the expected returns. By analysing factors such as asset classes, risk preferences and investment objectives, this thesis provides strategies and recommendations to help the average household develop a personalised investment recipe, using a combination of portfolio theory and empirical research.

Published: February 2024

Liquefaction of biomass is a practical source of clean liquid fuel and possible source of value-added chemicals. But if solid residual formed during liqufaction can’t be properly handled, it will be a new environmental problem. In this study, we use n-hexane and carbon disulfide to extract (under ultrasonic) the biomass residual from wheat stalk depolymerized in supercritical methanol. In the fraction extracted by n-hexane, Oxy-compounds and compounds containing benzene ring are present in high concentration. The fraction extracted by carbon disulfide is separated by column chromatography. The first sub-fraction eluted by n-hexane only detected three compounds, benzenethiol, diphenylmethane and diphenyldisulfide. The second sub-fraction eluted by n-hexane is mainly alkyl-benzenes and alkyl-cyclohexanes. Nine saturated fatty hydrocarbons from C21 to C29 are eluted in the sub-fraction eluted by mixture of n-hexane and benzene.

Authors: Fang Rui , Zhang Bo , Wang Hao , Chen Weihan , Wang Xiaoyin
Published: February 2024

The reasonable and reliable evaluation score calculation scheme wins the top priority in large-scale innovation-competitions currently. Due to the disparity among individual experts, and the existing standard score calculation model merely based on the experts' own circumstance, it cannot fully reflect the comprehensive level of players, resulting in a certain degree of error in the evaluation results. From the perspective of individual and decision-making of a group, this paper improves existing models and introduces the concept of modified scores. To verify the feasibility of the model, four schemes were designed based on the analysis of data distribution. Consistency and difference factors were applied to compare. Come to a conclusion: scheme adopted the new standard score calculation model ranked the top, indicating that the new calculation model is more reliable. Next, considering that the volatile correction factor affected by data, there is a possibility of some poor actual results with high correction scores. To rectify this case, a power exponent is added to the correction factor and a sign function is adopted to specify the positive or negative of correction scores. To verify the feasibility of the model, four sets of controlled experiments were designed with the introduction of two factors: power exponent and reconsideration bonus, as well as the ranking consistency test based on the condition that the award order of the expert agreement was consistent. In the end, it was found that the scheme that introduced both power exponent and reconsideration bonus points had a sorting consistency rate of 74%, which increased by 30% compared to the original model, indicating the rationality of the modification. The expert evaluation standard score calculation model established in this paper comprehensively considers individual and group decision-making, and provides reasonable correction for the differential scoring between experts. At the same time, this scheme provides a reference basis for further optimizing large-scale innovation competition plans in the future.

The Formation Mechanism of Abnormal Overpressure in Depositional Basins and Its Controlling Effect on Hydrocarbon Accumulation
Authors: Zhang Lu
Published: February 2024

Abnormal overpressure is commonly encountered in depositional basins and is considered a key factor influencing the efficiency, safety, and assessment of hydrocarbon accumulation dynamics in drilling projects. Research indicates the following: (1)The genesis of abnormal overpressure in depositional basins can be broadly classified into five types, including disequilibrium compaction, fluid expansion, diagenesis, tectonic squeezing, and pressure transmission;(2) For specific geological conditions in depositional basins, the mudstone logging curve chart method is employed to assess abnormal overpressure;(3) The impact of abnormal overpressure in depositional basins on hydrocarbon accumulation is manifested in four aspects: its influence on hydrocarbon generation from source rocks, its effect on reservoir connectivity, its impact on seal integrity of cap rocks, and its influence on hydrocarbon migration. These research findings provide crucial guidance for a deeper understanding of abnormal overpressure in depositional basins and its significance in the evaluation of hydrocarbon exploration.
