Проведено исследование формирования микро- и нанокристаллических поверхностных слоев сплавов при воздействии гетерогенных плазменных потоков по механизму возникновения и развития неустойчивости Кельвина-Гельмгольца на примере систем Ti–B и Ti–C–B. Особое внимание уделялось начальной стадии ее развития, когда возмущения границы раздела сред считались синусоидальными. Течение первой и второй среды считались вязко-потенциальными. Из дисперсионного уравнения возмущений границы раздела сред была получена зависимость скорости роста возмущений от волнового числа. Ее анализ показал, что в плоскости параметров (ε, m) существует восемь областей, в которых она может быть аппроксимирована приближенными зависимостями: αI ‒ IV, αI/ ‒ IV/. Из данных зависимостей получены связи волнового числа, на которое приходится максимум скорости роста возмущений и характеристик материала, параметров внешнего воздействия. Показано, что в зависимости от поперечной скорости второго слоя, соотношения вязкостей и плотностей слоев относительные погрешности этих приближений составляют 1-12 %. Максимумы скорости роста возмущений поверхности раздела сред делятся на два типа: гидродинамический и вязкостно-обусловленный. Гидродинамический максимум, который возникает вследствие взаимного скольжения слоев, существует во всех областях на плоскости параметров (ε, m). Вязкостно-обусловленный максимум возникает в областях II и III при условии m > 0,4767, а также в II/ и III/ при m < 0,4767. В области I при условии гидродинамический и вязкостно-обусловленный максимум существуют одновременно. Полученные результаты были применены для процессов электровзрывного борирования и карбоборирования титана. Установлено, что на границе раздела титана и бора выполняется приближенная аналитическая зависимость с погрешностью 1 %, а максимум имеет гидродинамическое происхождение. Это же приближение выполняется и в случае карбоборирования на границе раздела «плазма/расплав».
ДИСКРЕТНЫЙ БРИЗЕР В МОДЕЛЬНОЙ 3D ОЦК РЕШЁТКЕ Cr2Al CО СВЕРХСТРУКТУРОЙ C11b, ОСНОВАННЫЙ НА ДЕЛОКАЛИЗОВАННЫХ МОДАХ

Published: September 2023

Нелинейные локализованные колебательные моды большой амплитуды с частотой колебаний за пределами фононного спектра называют дискретными бризерами (ДБ). Различают щелевые и т.н. ДБ с жёстким типом возбуждения. Первые возбуждаются в двухатомных кристаллах, например, в упорядоченных сплавах, атомы компонент которых значительно различаются по массе. Такие кристаллы имеют щель в плотности фононных состояний, внутри которой может находиться частота щелевого ДБ. Бризеры второго типа, как правило, имеют место в моноатомных кристаллах. Известно также, что они были получены и в некоторых двухатомных кристаллах. В данной работе изучается возможность возбуждения ДБ в кристалле Cr2Al. Хром-алюминиевые сплавы имеют большое практическое применение в электронагревательных устройствах большой мощности и промышленных электрических печах. Условия работы этих устройств создают предпосылки для возбуждения ДБ в кристаллической решётке сплавов, из которых изготавливают нагревательные элементы. Интерес к изучению возможности существования ДБ в указанном сплаве, связан с тем, что бризеры оказывают влияние на физические свойства материалов, могут снижать теплопроводность за счёт рассеяния фононов, а также способствуют возникновению и миграции дефектов. В работе была построена 3Dмодель ОЦК кристаллической решетки Cr2Al со сверхструктурой C11b. Рассчитаны коэффициенты потенциала Морзе, посредством которого осуществлялось взаимодействие между атомами.Рассмотрена возможность возбуждения ДБ в указанном модельном кристалле. Для поиска ДБ использовали методики, разработанные в работах Чечина Г.М., Сахненко В.П. с соавторами, а также Дмитриева С.В. с коллегами. Рассматривается также причина неустойчивости ДБ жёсткого типа возбуждения и их быстрого затухания, а также один из механизмов рассеяния энергии.

Published: September 2023

Sensing small molecules, including drugs and their metabolites inside cells, is critical for drug discovery and development, diagnostics, and precision medicine. To facilitate sensitive, long-term studies of drug uptake in cultured cells and animals, we developed a genetically-encoded aptamer biosensor platform for non-invasive real-time measurements of drug distribution. We combined the high specificity of aptamer molecular recognition with the easy-to-detect properties of fluorescent proteins. We tested six different aptamer biosensors, showcasing the platform versatility. The biosensors display high sensitivity and specificity for detecting their specific drug target over related analogs. Furthermore, the biosensor responses were dose dependent and could be detected in individual live cells. We designed our platform for easy integration into animal genomes; thus, we incorporated one aptamer biosensor into zebrafish, an important model vertebrate. The biosensor was stably expressed and enabled non-invasive drug biodistribution imaging in whole animals across different timepoints. To our knowledge, this is the first example of an integrated aptamer biosensor encoded by a vertebrate animal. As such, our aptamer encoded biosensors address the need for non-invasive whole animal biosensing ideal for pharmacokinetic-pharmacodynamic analyses that can be expanded to detect diverse molecules of interest. Furthermore, due to the lack of species-specific machinery, our biosensors can be potentially adapted for any model organism of interest.

Published: September 2023

Rapid analysis of materials characterization spectra is pivotal for preventing accumulation of unwieldy datasets, thus accelerating subsequent decision-making. However, current methods heavily rely on experience and domain knowledge, which not only proves tedious but also is hard to keep up with the pace of data acquisition. In this context, we introduce a transferable Vision Transformer (ViT) model for identification of materials from their spectra, including XRD and FTIR. First, an optimal ViT model was trained to predict metal organic frameworks (MOFs) from their XRD spectra. It attains prediction accuracies of 70%, 93%, and 94.9% for Top-1, Top-3, and Top-5, respectively, and a shorter training time of 269 seconds in comparison to a convolutional neural network model. The dimension reduction and attention weight map underline its adeptness at capturing relevant features in the XRD spectra for determining the prediction outcome. Moreover, the model can be transferred to a new one for prediction of organic molecules from their FTIR spectra, attaining remarkable Top-1, Top-3, and Top-5 prediction accuracies of 84%, 94.1%, and 96.7%, respectively. The introduced ViT based model would set a new revenue to handling diverse types of spectroscopic data, thus expediting the materials characterization processes.

Published: September 2023

A chemical model for the ethylene receptor in higher plants has been supported through the synthesis, spectroscopy, and structural characterization of several copper complexes with model ligands representing those in the native receptor protein, combined with alkene ligands. Some corresponding silver complexes have been investigated owing to the well-known effects of silver ion as an inhibitor of ethylene physiological action.
Modular Synthesis of Templated Bimetallic Sites in Metal–Organic Framework Pores
Authors: Geary Jackson , Aalto Jonathan P. , Xiao Dianne J.
Published: September 2023

Binuclear metal active sites are found throughout all subfields of catalysis, from homogeneous and heterogeneous systems to enzymes. Here, we report a synthetic route to install well-defined bimetallic sites in metal–organic frameworks that offers independent control over the ligand environment, metal identity, metal–metal distance, active site flexibility, and pore environment. Our approach uses thermolabile tertiary carbamate crosslinkers to template pairs of amine functional groups within framework pores. The templated amine pairs can be quantitatively converted into diverse chelating sites, such as iminopyridine and bis(2-pyridylmethyl)amine ligands, and metalated with a variety of metal cations (M = Mn(II), Fe(II), Co(II), Ni(II), Cu(I), and Cu(II)). A combination of density functional theory, extended X-ray absorption fine structure spectroscopy, and electron paramagnetic resonance spectroscopy is used to confirm the local coordination environment and support the proximal nature of the templated bimetallic sites. The templating strategy described here will enable the exploration of new bimetallic motifs in heterogeneous catalysis.

Published: September 2023

We present a statistical learning model relying on a small dataset to predict the selectivity of a two state system toward the same substrate, specifically of redox-switchable metal complexes in the ring opening polymerization of e-caprolactone or trimethylene carbonate. We mapped the descriptor space of several switchable metal complexes and surveyed a set of supervised machine learning algorithms using different train/test validation methods on a limited dataset based on experimental studies of ca. 10 metal complexes. Linear discriminant analysis showed an accuracy of >80% and a F1 score of 0.86 on a test mixture of experimental and predicted molecules, and successfully predicted the reactivity of three new metal complexes. The established method will be used to guide future studies in recommending promising new metal complexes for related substrates, reducing the need for blind synthetic trial and error efforts.

Plagiarism in the Research Reports of Indian Doctoral Students: Causes and a Remedial Action Plan
Authors: Pradhan Tapan Kumar , Kumar Ajit
Published: September 2023

Many reputable academic journals have retracted research papers from Indian researchers because of plagiarism. The University Grant Commission, a representative organisation of the Indian government, is diligently endeavouring to ensure academic integrity by applying stringent guidelines. The present study aims to find the potential causes of the plagiarism found in the research reports of Indian doctoral students and to formulate a remedial action plan. A literature review was undertaken to identify incidences of plagiarism at educational institutions. Based on the review’s insights, a survey was conducted to investigate doctoral students’ awareness of plagiarism, including causes and remedial action plans. In addition, 21 interviews were conducted with senior academics and professionals from various academic disciplines to gain an understanding of their viewpoints. An analysis was then undertaken of the responses received through the questionnaires and interviews. The results suggested the widespread incidence of plagiarism and shed light on its causes. A remedial action plan emerged from the study, which included 1) establishing a research ethics committee at all academic or research institutions, 2) fostering a correct understanding of plagiarism and its implications by conducting training, workshops and awareness campaigns at an early stage of doctoral students’ lives, 3) ensuring clarity of research purpose among doctoral students and emphasising the quality of research work, 4) developing academic writing skills, and 5) making anti-plagiarism software available free of charge to all students and faculty members. Indian students perceive the University Grant Commission’s stringent guidelines as a good initiative. However, these guidelines cannot be implemented fruitfully without addressing the underlying causes of plagiarism.

Authors: Zhang Dingyi
Published: September 2023

During the Northern Warlord Period (1912–1928), the construction industry in Shanghai underwent robust development. As an integral element of buildings, equipment served both functional purposes and stood witness to the evolution of the economy and society, thus earning its place as part of the architectural heritage. However, due to various reasons, there are many loopholes in the protection of these building equipment. This paper examines the development of building equipment in Shanghai during the Northern Warlord Period, using water supply, drainage, and heating, ventilation, and air conditioning (HVAC) systems as examples. Through historical context analysis, it summarizes this development from a social-spatial perspective, infers the reasons behind it, and analyzes the importance of preserving such equipment, considering both past and present viewpoints. In this research, the importance of protecting historical building equipment is emphasized, which aims to give people a deeper understanding of their cultural value, and suggests that scholars conduct more practical research on their protection.

Published: September 2023

Abstract: Esophageal cancer is one of the common malignant tumors in China with a high mortality rate. Neoadjuvant chemoradiotherapy (nRCT) is currently the primary treatment method for locally advanced esophageal cancer. However, nRCT has not been not widely applied in China due to several reasons. First, the radiotherapy equipment and technology vary in different regions, and the learning curve for these technologies is steep, making rapid implementation difficult. Furthermore, the combined toxicity of radiotherapy and chemotherapy can counteract the survival benefits of preoperative treatment. In recent years, a promising approach involves combining neoadjuvant chemotherapy with immunotherapy for patients with locally advanced esophageal cancer. This article offers an overview of the progress in neoadjuvant therapy for this condition.
Integration of Huizhou Style Culture into Product Intention Expression in the AI Era——Take the Four Treasures of the Study as an Example
Authors: Wen Jianqiang
Published: September 2023

When it comes to Huizhou culture, many people first think of Huizhou style architecture and Huizhou merchants. In fact, the Four Treasures of the Study is also a representative branch of Huizhou culture. Since the Northern and Southern dynasties, the Four Treasures of the Study has become an indispensable carrier of Chinese cultural inheritance. However, with the development of the times, especially the progress of the internet economy, people’s lives and studies have begun to emphasize the word “cloud.” Writing can be done directly on mobile phones or computer screens using an electronic pen. Traditional study tools such as paper, ink, pen, and inkstone have gradually faded out of the sight of ordinary people. However, in recent years, with the close integration of traditional Chinese culture and the Internet, industries bearing the imprint of traditional Chinese culture have gradually revived, with Hanfu culture being the most representative. Many cities in China have held Hanfu cultural festivals with the popularity of Hanfu, increasing the call for the revival of traditional Chinese culture. This paper mainly analyzes the inheritance status of the Four Treasures of the Study, one of the representatives of Huizhou culture, by combining artificial intelligence (AI) technology, the driving force of Internet technology, and proposes three strategies on revitalizing the Four Treasures of the Study in the AI era, hoping to assist in the cause of rejuvenating Chinese traditional culture.

Risk Factors for Quantity of Cannabis Use Per Day among College Students Who Violated Their University Drug Use Policy
Authors: Montemayor Benjamin , Nabil Anas , Merianos Ashley
Published: September 2023

Background: Cannabis use among college students represents a continued public health issue. The objective was to assess risk factors and reasons for cannabis use among students who violated their university’s drug use policy, and whether risk factors influenced cannabis use quantity. Methods: This cross-sectional survey study included 99 college students enrolled at a large U.S. public university. Descriptive statistics were calculated, and an ordinary least squares regression analysis was conducted. Results: Students reported using cannabis an average of 7.4 (SD = 10.2) days in the past month, with 8% reporting daily use. On average, students consumed slightly over 0.25 (SD = 0.25) grams per day, with 40% reporting greater than one gram per day. The average age of onset of cannabis use was 16.8 (SD = 1.8) years old. The top reasons for cannabis use were to: relax or relieve tension (75.8%), feel good or get high (62.6%), and have a good time with friends (60.6%). Students perceived an average of 47% of their peers engaged in past-month cannabis use and only slight risk was associated with regular use. Students perceived their loved ones would mostly approve of a reduction in their cannabis use. Regression results indicated past-month cannabis frequency (p = .002) and being of racial/ethnic minority descent (p = .05) were positively associated with quantity of cannabis per day, while perceived risk of regular cannabis use ( = -0.21) was negatively associated. Conclusion: Evidence-based cannabis interventions for students who violate their university’s drug use policies are critically needed that aim to reduce cannabis use and mitigate its associated negative consequences.

Published: September 2023

Background

Neisseria meningitidis is a commensal bacterium which can cause invasive disease. Colonisation studies are important to guide vaccination strategies.

Aim

The study’s aim was to determine the prevalence of meningococcal colonisation, duration of carriage and distribution of genogroups in Iceland.

Methods

We collected samples from 1 to 6-year-old children, 15–16-year-old adolescents and 18–20-year-old young adults. Carriers were sampled at regular intervals until the first negative swab. Conventional culture methods and qPCR were applied to detect meningococci and determine the genogroup. Whole genome sequencing was done on groupable meningococci.

Results

No meningococci were detected among 460 children, while one of 197 (0.5%) adolescents and 34 of 525 young adults (6.5 %) carried meningococci. Non-groupable meningococci were most common (62/77 isolates from 26/35 carriers), followed by genogroup B (MenB) (12/77 isolates from 6/35 carriers). Genogroup Y was detected in two individuals and genogroup W in one. None carried genogroup C (MenC). The longest duration of carriage was at least 21 months. Serial samples from persistent carriers were closely related in WGS.

Conclusions

Carriage of pathogenic meningococci is rare in young Icelanders. Non-groupable meningococci were the most common colonising meningococci in Iceland, followed by MenB. No MenC were found. Whole genome sequencing suggests prolonged carriage of the same strains in persistent carriers.

Enteroviruses are a common cause of seasonal childhood infections. The vast majority of enterovirus infections are mild and self-limiting, although neonates can sometimes develop severe disease. Myocarditis is a rare complication of enterovirus infection. Between June 2022 and April 2023, twenty cases of severe neonatal enteroviral myocarditis caused by coxsackie B viruses were reported in the United Kingdom. Sixteen required critical care support and two died. Enterovirus PCR on whole blood was the most sensitive diagnostic test. We describe the initial public health investigation into this cluster and aim to raise awareness among paediatricians, laboratories and public health specialists.
The 8th Victor de Mello lecture: role played by viscosity on the undrained behaviour of normally consolidated clays
Authors: Martins Ian
Published: September 2023

Phenomena that do not obey Terzaghi’s principle of effective stress (PES) are related to strain rate and time effects. This issue led the author to refer to early articles in soil mechanics, which used to consider the shear resistance of clays as a combination of two components: a frictional and a viscous one. In these articles the viscous component was assigned to the distortion of highly viscous adsorbed water layer in the contact points between grains along the plane where shearing takes place. Assuming the shear resistance of plastic soils comprises frictional and viscous resistance components, a shear stress equation can be added to the PES. It is shown that Mohr’s circle of effective stress is the sum of two ellipses: the viscosity and the friction ellipses. The ordinates of the viscosity and the friction ellipses represent the viscous and the frictional components of shear resistance in different planes, respectively. This approach leads to a failure criterion considering strain rate, according to which failure takes place whenever the friction ellipse touches the strength envelope, which is the 'e φ sloped straight line passing through the origin, 'e φ being the Hvorslev’s true angle of friction. By adding such shear stress equation to the PES, a model that explains strain rate and time effects is developed. Predictions of the proposed model are compared to results from tests carried out on San Francisco Bay Mud specimens.

Authors: Darsono Caroline Illene Hari , Martono Cyrillius , Memarista Gesti
Published: September 2023

The current study compares the differences between Cumulative Abnormal Returns (CAR) and Cumulative Trading Volume Activity (CTVA) for publicly traded companies that execute stock splits in the year 2021 on the ASEAN Stock Exchange. According to estimates and timelines, businesses listed on the ASEAN Stock Exchange in 2021 are not permitted to take additional corporate action. There are 47 companies using the sampling exchange in the countries of Indonesia, Malaysia, Philippines, Vietnam, Thailand, and Singapore. The data analysis methodology used by researchers is a different test through the Wilcoxon Rank Test. The first result from this study is that there is a difference in CAR before and after a stock split that is significant. In contrast, for the second result, there is no significant difference in the CTVA for the prior and subsequent stock split. Before the stock split happened, researchers discovered a bigger discrepancy in CAR. This shows that the market responded from time t-31 to time t-1. Due to a number of reasons, including the global influence of dominant data and patterns in investor behavior, there was no discernible difference in the CTVA.

Authors: Gunawan Gunawan
Published: September 2023

Challenges in the industrial world related to employee turnover continue to occur until after the Covid-19 pandemic. Early indications of employee turnover can be predicted from organizational commitment and employee competence. The purpose of this study is to obtain the results of an analysis of the effect of organizational commitment and compensation on employee turnover of PT Bersama Zatta Jaya (Elzatta Hijab) both partially and simultaneously. This study uses quantitative research methods and uses path analysis as a hypothesis test, this is supported by data collection based on interviews, surveys and distribution of questionnaires to respondents. The population in this study were all employees of PT Bersama Zatta Jaya (Elzatta Hijab), with research sampling identifying employees who had an intention to leave the company. The population was too large using the slovin formula so that 211 respondents were obtained. The results showed that organizational commitment to turnover intention. in the Elzatta Hijab company was very low. Influencing factors include structured career development opportunities and a supportive work environment. Meanwhile, compensation has a fairly high influence, with the importance of fairness in salary and performance-based incentive programs. Simultaneously, organizational competencies also play an important role in influencing turnover intention. Overall, reducing employee turnover is a challenge that companies must face. However, by paying attention to factors such as organizational commitment, compensation, and career development, companies can reduce turnoverrates and create a stable and productive work environment.

Detection of Indonesian Hate Speech in the Comments Column of Indone-sian Artists' Instagram Using the RoBERTa Method
Authors: Azhari Adhe Akram , Sibaroni Yuliant , Prasetiyowati Sri Suryani
Published: September 2023

This study detects hate speech comments from Instagram post comments where the method used is RoBERTa. Roberta's model was chosen based on the consideration that this model has a high level of accuracy in classifying text in English compared to other models, and possibly has good potential in detecting Indonesian as used in this research. There are two test scenarios namely full-preprocessing and non full-preprocessing where the experimental results show that non full-preprocessing has an average value of accuracy higher than full-preprocessing, and the average value of non full-preprocessing accuracy is 85.09%. Full-preprocessing includes several preprocessing stages, namely cleansing, case folding, normalization, tokenization, and stemming.

İnsanoğlu tarihin ilk çağlarından beri taş ve toprağa şekil vererek bu kaynaklardan çeşitli şekillerde yararlanmıştır. Sanayi devrimiyle birlikte sektörde başlayan makineleşme; üretimin hızlanmasına, ürünlerin çeşit ve kalitesinin
artmasına ve endüstriyel ürünlerin yaygın bir şekilde kullanılmasına olanak sağlamıştır. Taş ve toprağa dayalı sanayii, başta konut olmak üzere her türlü inşaat faaliyetlerinde kullanılmak üzere çimento, tuğla, kiremit, seramik,
beton, alçı gibi ürünlerin imalatını gerçekleştirir. Bu çalışmada; Sanayi Coğrafyası prensipleri çerçevesinde, Eskişehir ili özelinde taş ve toprağa dayalı sanayilerin tarihsel gelişimi, mevcut durumu, sorunları ve mekânsal etkilerinin
ortaya konulması amaçlanmaktadır. Elde edilen bulgulardan hareketle sektörün sorunlarına dönük çözüm önerileri getirilmiştir. İl kapsamında evreni temsil edecek güçte ve çeşitli alt sektörlerde 11 adet taş ve toprağa dayalı sanayii
işletmesine 2019 Temmuz ve Ağustos ve 2020 Temmuz ayında anket uygulanmıştır. Uygulanan anketlerden elde edilen veriler betimsel analizine uygun olarak yorumlanmış ve sektöre dair elde edilen sonuçlardan hareketle öneriler getirilmiştir.
Eskişehir ilinde taş ve toprağa dayalı sanayii 1927 yılında kurulan Kılıçoğlu Kiremit Fabrikası ile başlamıştır. İlerleyen yıllarda taş ve toprağa dayalı sanayiinin diğer alt sektörlerinde faaliyet gösteren işletmelerin kurulmasıyla
gelişim göstermiştir. İl’de faaliyet gösteren imalat sanayii işletmelerinin %7,84’ü taş ve toprağa dayalı sanayii işletmelerinden ibarettir. Ayrıca ildeki imalat sanayii istihdamının %12,95’i taş ve toprağa dayalı sanayilerde istihdam
edilmektedir. Eskişehir ilinde taş ve toprağa dayalı sanayii kuruluşları; pazar, talep istikrarsızlığı ve rekabet fazlalığı konularında sorunlar yaşamaktadır. Anket yapılan işletmelerin %45,45’i katı-sıvı atık, %36,36’sı yatay
yönde büyüyememe ve %27,27’si görüntü kirliliği oluşturma sorunları yaşadıklarını dile getirmişlerdir. Atık sorununu ortadan kaldırabilmek için arıtma tesisi olmayan işletmelerin Eskişehir Organize Sanayi Bölgesi’ne taşınmalarının
teşvik edilmesi gerekmektedir.

Bu çalışmanın amacı, masa başı çalışan kadın ve erkeklerde fiziksel aktivite düzeyi ile yaşam kalitesi farklılıklarını ve bu parametreler arasındaki ilişkiyi araştırmaktır. Bu araştırmanın evrenini bir kamu kurumunun İstanbul merkezli
şubelerinin tüm personeli, örneklemini ise bu evrenden çalışmaya katılmayı kabul eden kadın (n=152) ve erkek (n=148) toplam 300 kişi oluşturmaktadır. Çalışmada, bireylerin fiziksel aktivite düzeylerini belirlemek için Uluslararası
Fiziksel Aktivite Anketi’nin kısa formu (UFAA Kısa Form - International Physical Activity Questionnaire Short Form), yaşam kalitelerinin değerlendirilmesi amacıyla da SF–36 yaşam kalitesi ölçeği kullanılmıştır. Araştırmadan elde
edilen sonuçlara göre, bireylerin %27’sinin fiziksel olarak aktif olmadığı, %41.3’ünun fiziksel aktivite düzeyinin düşük olduğu ve %31.7’sinin de fiziksel aktivite düzeyinin sağlığını korumak için yeterli olduğu saptanmıştır. Kadın
ve erkelerin toplam fiziksel aktivite puanları arasında istatiksel olarak anlamlı fark bulunmamıştır (p>0,05). Fiziksel aktivitesi düşük olan kadınların genel sağlık algısı puanları fiziksel aktivitesi yeterli olan kadınların
genel sağlık algısı puanlarından anlamlı olarak daha yüksek olduğu saptanmıştır (p<0,05). Sonuç olarak masa başı çalışanların büyük çoğunluğunun fiziksel aktivite düzeyi düşüktür ve cinsiyetler arasında fiziksel aktivite açısından
fark bulunmamıştır. Cinsiyet farkı gözetmeksizin masa başı çalışanlar fiziksel aktiviteyi teşvik eden eğitim ve imkanlar sağlanmalıdır. Özellikle fiziksel aktivitesi düşük olan kadınların risk algıları değerlendirilerek uygun aktivitelere
teşvik edilmelidir.
