Published: August 2023

The role of parents, particularly mothers, is very important in the process of child development. Limited knowledge of mothers can affect the nutritional status of infants and increase the risk of stunting. This study aims to determine the relationship between mothers' knowledge of balanced nutritional food and the incidence of stunting in toddlers in Pasirbatang Village, Tasikmalaya Regency in 2022. This is a quantitative research design with a cross-sectional approach with a sample of 70 mothers with toddlers. Sampling in this study was stratified random sampling. The variables studied were mother's knowledge and the incidence of stunting, with the research instrument in the form of a questionnaire. The results showed that there was no significant relationship between mother's knowledge about infant nutrition fulfillment and the incidence of stunting in Pasirbatang, Tasikmalaya Regency, 2022 because the <p-value (0.05 <0.769). This is possible because there are other variables that influence the incidence of stunting such as parenting style, exclusive breastfeeding and infectious diseases. Parents must equip themselves with the knowledge and skills to meet the nutritional needs of their babies so as to avoid the risk of stunting

Elaine Chew exposes the impact of diaspora, dimensions of human mobility, and connectivity, in “The Heartsick Diaspora” (2019). It is about an ethnic writing group of mixed-Asian blood in London. The striking cultural differences between their native culture (Eastern) and foreign culture (Western) significantly affect the characters in the story. This study belongs to literary criticism using a formalism approach to analyze the diasporic phenomenon in the literary work. It explores the connection between the settings and qualities of the two characters in the story, namely Chandra and Wei. Chandra's personality is different from the typical Asian woman because she is cynical, often dresses androgynous, and upholds individual freedom. On the other hand, Wei, a new member of the ethnic group, seems to hide his sexual orientation from the group because it considers immoral in Eastern culture.  Eventually, Elaine Chew portrays the influence of the diaspora which affects the characterization of someone because they have to adapt to their new environment but also cannot be completely separated from their roots.

Published: August 2023

Naming is searching for language symbols to describe objects, concepts, and processes by utilizing vocabulary through changes in meaning or the creation of words. Toponyms are used as the identity of a place because they come from the results of the culture of the people in the area, which originate from the reciprocal relationship with the environment, in this case, namely language. The name of the place cannot be separated from the characteristics or things related to the place, such as the name of the sub-district in Banyumas Regency. This research is descriptive qualitative. The object of study of toponyms in this research is the naming of sub-districts in Banyumas Regency, which have physical and cultural characteristics that can be traced from an event or event in the past. The toponymy of sub-districts in Banyumas Regency can be a source of local history for the Banyumas people. Myths are passed down from generation to generation as part of the local history of place names. The history of naming is an oral tradition passed down from generation to generation, so naming places has cultural value. There are also local wisdom values in the sub-district toponymy in Banyumas Regency. The research results show that the sub-district toponyms in Banyumas Regency can trace the values behind the naming stories, namely the social and cultural values of the stories or myths of the Banyumas people. This local topography value in Banyumas Regency can be used as a source of learning for the younger generation.

Published: August 2023

Advertisement has the potential to exploit female figures elaborated with particular signs or language that allude to gender bias in society to achieve commercial goals. One of the representations of women in advertisements shows the social position of women as subordinated figures in the domestic areas. This strategy is also applied in Yoga Arizona’s Happyfresh #BikinMertuaHappy advertisement posted on his Instagram account on July 25, 2020. This study examined the image of the ideal housewife as depicted in that advertisement. The research data include the visual and textual elements sourced from the video and caption in the advertisement. The depiction of the ideal housewife was analyzed using the Critical Discourse Analysis approach by Sara Mills (2003), examining the subject-object and writer-audience positions. This study has identified that the housewife plays double roles as the subject and the object in the advertisement, and the writer positions the audience as those who share common characteristics with the main character.  This study has revealed that the ideal housewife depicted is the one that is capable, attentive, and reliable in taking care of the family to meet the mother-in-law’s standards. The positioning of women in the advertisement supports the gender imbalance in a domestic context.

Published: August 2023

The development of high-efficiency photocatalysts plays an important role in the application of solar energy conversion. Titanium dioxide (TiO2) with an anatase crystalline phase is well-known as semiconductor thin layers for solar cells. This work has constructed a novel TiO2 hollow sphere (HST) in a 2-step synthesis. The first step is coating the SiO2 template with TiO2 to build a core-shell of SiO2@TiO2 (CSST). The second step is etching via sonication to elute the SiO2 from CSST and construct the HST. The annealing of CSST for 1 to 6 hours and etching for 1 to 7 hours has resulted in the HST with different crystallite sizes and microstrains. The HST of ~90 nm has been fabricated with crystallite size of 9.53 to 20.54 nm and microstrain from 0.34 to 3.42. It was found that the optimum crystallite size and microstrain of HST obtained via annealing the CSST for 2 hours and etching for 5 hours has the best photooxidation of I- under UV irradiation. The optimum crystallite size and microstrain of HST via annealing and etching times can be recommended for the future of solar cell fabrication and applications.

Published: August 2023

Gouramy (Osphronemus gouramy) has very high economic value and is easy to cultivate. Currently there are about six strains that have been successfully cultivated based on their reproductive ability to produce eggs, namely goose (soang, goose gouramy), jepun (japan, japonica), blue sapphire, paris, bastar (broiler) and porcelain. One of the reasons for these differences in ability is internal factors which can be seen through the identification and expression of the cGnRH gene that each of these gouramy strains have. The cGnRH gene functions in signaling the pituitary gland to secrete the hormone GtH. This study aims to identify sequences and gene expression values ​​resulting from three strains of gouramyat different age levels. The research method used was the exploration of three gouramy strains (soang, jepun, blue sapphire) at different age levels (4 months, 8 months, 12 months), and three gouramy strains were taken for each age level. This research was conducted through several stages, namely organ preparation, isolation, sequence identification and measurement of cGnRH gene expression. Sequence data was analyzed using phylogenetic trees and gene expression was analyzed using One Way ANOVA test. The sequence results showed that the soang strain had a sequence that was more similar to the jepun strain than the blue sapphire strain, and the resulting gene expression showed that the three gouramy strains with three different age levels did not give different results.

This study investigates uranium solvent extraction under AMEX process conditions. The use of pure extractants without diluents or phase modifiers allows not only to reduce the use of volatile organic compounds, but also to provide higher extraction yields without third phase formation. Pure extractants are protonated amines or quaternary ammoniums with suitable counter ion, which act at the interface between ion pairs and protic ionic liquids. The mixture of sulfates anion (SO42-) and bis(trifluoromethanesulfonyl)imide anion (NTf2-) revealed unexpected nonlinear extraction behaviors, which appear highly important to rationalize for optimized application. Spectroscopic analysis (NMR, UV-vis, FT-IR, and EXAFS) showed that uranium extraction occurs via protonated amine and three sulphates. Nonlinear extraction could further be interpreted by considering water and acid transfer between the two phases: at lower sulphate ratios, the release of acid from the organic phase into the aqueous phase was shown to influence the number of protonated amines in the organic phase, affecting uranium extraction before its enhancement. Furthermore, the extraction loss at higher sulphate ratios, was assigned to the destabilization of bidentate uranium-sulphate complexes due to a competition between water and sulphates.

Peripheral nerve injury remains a medical challenge with no easy resolution. Over the last few decades, significant advances have been achieved in promoting peripheral nerve regeneration, and new assessment tools have been developed, both functional and imaging, to quantify the proportion and quality of nerve recovery. The exploration of new animal models, larger, more complex and with more similarities to humans, has made it possible to reduce the gap between the results obtained in classic animal models such as rodents and the application of new therapies in humans and animals of clinical interest. Ultrasonography is an imaging technique recurrently used in clinical practice to assess the peripheral nerves, allowing its anatomical and topographic characterization, and aiding in the administration of anesthesia and in the performance of nerve blocks. The use of this technique in animal models is scarce, but it could be a useful tool in monitoring the progression of nerve regeneration after the induction of controlled experimental lesions. In this work, sheep, a promising animal model in the area of peripheral nerve regeneration, were subjected to an ultrasonographic study of three peripheral nerves of the hind limb, the common peroneal, tibial and sciatic nerves, in order to establish values of dimensions and ultrasound appearance in healthy nerves and also landmarks for their identification. At the same time, an echographic evaluation of the cranial tibial muscle, an effector muscle of the common peroneal nerve, was also carried out, establishing normal values for the echographic aspect and dimensions. The results obtained will allow the use of these data as control values in future work exploring new therapeutic options for nerve regeneration after induction of common peroneal nerve injuries in sheep.

Published: August 2023

The green peach aphid, Myzus persicae (Sulzer) (Hemiptera: Aphididae), is an economically important pest of crops worldwide. A M. persicae (SEF-R) population from a cabbage field in southeastern China was tested for susceptibilities to 13 insecticides. Compared with the susceptible clone (FFJ-S), extremely high and high-resistance to beta-cypermethrin (324-fold) and imidacloprid (106.9-fold) were detected in SEF-R. More importantly, this is the first report of resistance in field M. persicae population to sulfoxaflor, flupyradifurone, pymetrozine, spirotetramat, flonicamid, and broflanilide in China. The resistance factor decayed to a low level to sulfoxaflor and pymetrozine after 15 generations without any selection pressure. The resistance-related mutations (R81T and kdr) were detected in SEF, conferring target-site resistance to neonicotinoids and pyrethroids, respectively. Biochemistry bioassays confirmed the involvement of monooxygenase enzyme, carboxylesterase, superoxide dismutase and peroxidase in multi-insecticide resistance mechanism. The overexpression of P450s, esterases, and a UDP-glycosyltransferase, might be responsible for the multi-insecticide resistance in SEF-R. The knockdown of CYP6CY3 in SEF-R increased its susceptibility to imidacloprid, thiacloprid, and thiamethoxam, which verified that P450s play vital roles in neonicotinoid metabolism. This study will be helpful for chemical control, as well as for resistance monitoring and management of GPA, in China.

Published: August 2023

Fe- and Al-rich metapelite from the Transangarian segment of the Yenisey Ridge (East Siberia, Russia) is a potential new source of high-alumina refractories. The rocks have relatively high average contents of Al2O3 (20 wt.%) and Fe2O3 (7.91 wt%), moderate K2O (3.44 wt%), and low CaO (0.74 wt%). Their dominant mineral assemblages are andalusite + muscovite + margarite + chlorite + biotite + quartz or staurolite + kyanite or/and andalusite + chlorite + muscovite + biotite + quartz with ±garnet and ±plagioclase. Al2SiO5 polymorphs occur as up to 1.5 cm andalusite porphyroblasts and partial or complete pseudomorphs after andalusite (kyanite and staurolite). Accessories include abundant Fe-Ti oxides and sporadic REE-, Y-, Ca-phosphates; sulfides are negligible. The composition of Al2SiO5 concentrates obtained in laboratory by heavy-media and magnetic separation from ≥0.06 mm fractions meet all requirements for raw material of this type: >56 wt% Al2O3, <42 wt% SiO2, <1 wt% Fe2O3, <1.2 wt% TiO2, and <0.2 wt% (CaO+MgO). The andalusite, kyanite, and mixed ores yield 0.7-4.1 wt%, 0.7-2.2 wt%, and 1.9-6.0 wt% of concentrate, respectively. The best-quality ores rich in Al2SiO5 polymorphs reside in zones of contact and/or dynamic metamorphism superimposed over regional metamorphism of Al-rich rocks.
Effect of GABA-Transaminase Inhibitor 3-MPA on Arabidopsis thaliana Grown Under Different Light Conditions
Authors: Njimona Ibrahim , Yamashita Felipe , Baluška František
Published: August 2023

The adaptation of plants to biotic and abiotic stress depends on their abilities to sense their surroundings and to generate and transmit corresponding signals to different parts of their body that can evoke changes necessary for optimizing growth and defense. Light has been shown to be one of the key environmental factors that modulate the physiology of both plants and animals via the diverse photoreceptors found in them. Both plants and animals contain a large repertoire of intra- and intercellular signals molecules that include organic and inorganic. One such molecule is a neurotransmitter, γ-aminobutyric acid (GABA), a non-protein amino acid, that rapidly accumulates in plant tissues in response to biotic and abiotic stress and regulates plant growth. Lots of research has been done on GABA in plants for slightly more than half a century now: Its discovery in plant tissues was immediately followed by physiological and biochemical studies. Thereafter molecular-genetics era of cloning the genes encoding the GABA shunt enzymes and transporters, and recombinant expression and purification of the enzymes in vitro to elucidate their regulatory properties and substrate specificity was established. Recently the discovery of the first bona fide GABA target proteins in plants, the ALMTs suggest that GABA indeed could be one of the signaling molecules in plants. All this research did not address in detail the relationship between light and GABA. To better understand the role of GABA in relation to light we set up six light conditions to investigate the changes in the hypocotyl and root growth in Arabidopsis thaliana under different light conditions, including total light, total dark, light blocker, gradient light, shoot dark, shoot dark with blocker. We treated the seedlings with 3-MPA, a GABA inhibitor, using different concentrations grown under different light conditions between 24 to 96 h. Our results show that both the root and hypocotyl are modulated by GABA when grown under different light conditions. These results clearly suggest a link in the signaling pathway of GABA with photoreceptor signaling pathways.
In vitro Embryogenesis and Gastrulation using Stem Cells
Authors: Oh Seung Yeon , Na Seung Bin , Kang Yoo Kyung , Do Jeong Tae
Published: August 2023

During early embryonic development, fertilized one-cell embryos develop into preimplantation blastocysts and subsequently establish three germ layers through gastrulation during post-implantation development. In recent years, stem cells have emerged as a powerful tool to study embryogenesis and gastrulation without the need for eggs, allowing the generation of embryo-like structures known as synthetic embryos or embryoids. These in vitro models closely resemble early embryos in terms of morphology and gene expression and provide a faithful recapitulation of early pre- and post-implantation embryonic development. Synthetic embryos can be generated through a combinatorial culture of three blastocyst-derived stem cell types, such as embryonic stem cells, trophoblast stem cells, and extraembryonic endoderm cells, or totipotent-like stem cells alone. This review provides an overview of the progress and various approaches in studying in vitro embryogenesis and gastrulation using stem cells. Furthermore, recent findings and breakthroughs in synthetic embryos and gastruloids are outlined. Despite ethical considerations, synthetic embryo models hold promise for understanding mammalian (including human) embryonic development and have potential implications for regenerative medicine and developmental research.

Published: August 2023

» Universal safety guidelines for the use of a knee-spanning external fixator in magnetic resonance imaging (MRI) are unlikely to be established considering the high variability in device construct configurations.

» Per the US Food and Drug Administration, manufacturers are to provide parameters for safe MRI scanning for “MR Conditional” devices; however, such labeling may be limited in detail. Physicians should reference manufacturer labels as a starting point while making an educated clinical decision.

» Scanning of a knee-spanning external fixator inside the MR bore has been safely demonstrated in previous studies, although with small sample sizes.

» When considering MRI in a patient treated with a knee-spanning external fixator, physicians should use all available resources and coordinate with their medical team to make a clinically reasonable decision contrasting patient benefit vs. potential harm.

Authors:   Korean Association of Public Safety and Criminal Justice, Kim Kaeun , Kim Yeonsoo
Published: August 2023

The current criminal justice system has limitations in providing victim protection services before stalking victims actively request intervention. Therefore, this study aims to report to investigative agencies such as the police and propose measures to diagnose the risk on their own and prevent additional serious criminal damage to potential victims before protection is made. This study proposes the development of a victim's risk self-diagnosis tool from a stalking risk assessment tool through a review of previous studies. Specifically, it was suggested to consider the relationship between the perpetrator and the victim, and to select and utilize common risk factors from existing risk assessment tools. In addition, a procedure is required to objectively confirm the victim's subjective risk perception. As a result of self-diagnosis of stalking victims, it was proposed to provide customized crime victim safety measures according to the risk level of stalking victims, secure the effectiveness of access restriction orders through the introduction of two-way electronic supervision.

Authors:   Korean Association of Public Safety and Criminal Justice, Lee Seung-Hyun
Published: August 2023

The main purpose of this study was to test whether the factors of impulsivity, parental neglect, and smartphone addiction among out-of-school youth affect cyber violence indirectly or directly through the mediation of delinquent peer variables. The data used in this study were from the fourth year (2016) of the Korean Youth Policy Research Institute's Panel on Out-of-School Youth (PSSDY). A structural equation model was applied to carry out the research objectives. The results showed that the impulsivity variable not only influences cyber violence through mediating discriminatory contact with delinquent peers, but also directly leads to cyber violence. The parental neglect factor did not directly affect cyber violence, but indirectly affected the dependent variable through delinquent peers. On the other hand, the smartphone addiction factor was found to have a direct effect on cyber violence, but not indirectly through contact with delinquent friends. This study proved that among the many factors that can affect cyber violence among out-of-school youth, the variable of discriminatory contact with delinquent friends has a significant impact. Therefore, it is urgently necessary to develop cyber violence prevention programs that can block discriminatory contact with delinquent friends among out-of-school youth.

Published: August 2023

In order to dispel concerns about the police's enlargement of power due to the adjustment of investigative powers and to successfully establish an local police system, it is necessary to be reborn as a human rights-friendly police force. Through in-depth interviews with police officers, this study sought to find out the current status and problems of human rights protection activities, focusing on the organization and work in charge, and to obtain implications for establishing human rights-friendly police activity strategies. For the purpose of the study, in-depth interviews were conducted with 15 police officers in charge of human rights and investigation departments. As a result of the in-depth interview, various organizational problems such as the organization and personnel in charge of police human rights, problems of human rights education, wrong investigation practices, and a performance-oriented culture were identified. Based on the interview results, it was proposed to establish a human rights department and redefine the rights and roles of the Human Rights Commission. In addition, strategies for human rights-friendly police activities were presented, such as concrete plans for human rights education contents and methods, improvement of organizational culture, human rights measures for the socially underprivileged, and strengthening of internal human rights in the police.

Published: August 2023

The purpose of this study is to analyze the factors to influence investigators' job engagement based on the job demand-resource model. This study verifies whether the job demand-resource model, which has been mainly verified in foreign countries, can be applied to investigation department of South Korea, and suggests the measures to improve investigators' job engagement. The dependent variables of this study are the investigator's job engagement, and the independent variables are job demands(job overload, work-family conflict), job resources(distributive fairness, self-development opportunities, performance feedback), social resources(manager support, peer support), and control variables are socio-demographic variables. The results of multiple regression analysis showed that self-efficacy(β=.358), self-development opportunities/performance feedback(β=.265), distributive fairness(β=.170), manager support(β=.139) had a statistically significant effect on the investigator's job engagement. Therefore, in order to improve the level of the investigator's job engagement, investigation department should make much of efforts to increase the investigator's self-efficacy, provide more opportunities for self-development and performance feedback, and enhance perceived distributive fairness and manage support.

Published: August 2023

The species richness in Neotropics has been linked to environmental heterogeneity and a complex geological history. We evaluated which biogeographical processes were more associated with the diversification of Monkey tree frogs, an endemic clade from the Neotropics. We tested the hypothesis that the diversification of Phyllomedusinae occurred in a south-north direction in the Neotropics, and that marine introgressions and Andean uplift had a crucial role promoting their diversification. We used 13 molecular markers on a bayesian analysis to infer phylogenetic relationships among 57 species of Phyllomedusinae and to estimate their divergence times. We defined 12 biogeographical units based on landscape modifications and species distribution. Ancestral range estimations were made by models implemented in BioGeoBEARS. We found that the Phyllomedusinae hypothetical ancestor range was probably widespread through the Neotropics, from Central America to Southern Atlantic Forest, at 38.6 Mya. Phyllomedusines' ancestors diverged mostly through vicariance during early stages of speciation, generally followed by jump-dispersals and speciation in sympatry. Dispersal among areas mostly occurred from Western Amazonia towards Northern Andes and the diagonal of dry landscapes, rejecting our south-north diversification hypothesis. Our results revealed a complex diversification of Monkey tree frogs, occurring simultaneously with the orogeny of Northern Andes and the South American marine introgressions in the last 30 million years.

Published: August 2023

This paper deeply explores about the millimeter-wave massive MIMO (mmWavemMIMO) and inter user interference which develops a key factor for preventive system capacity. The idea of increasing system capacity by grouping algorithm is to reduce inter group interference by assuring high receiving power. As a result of this circumstance, this paper proposes the strong user dependent (SUD). We divide users into groups based on their correlation threshold and channel correlation. Users with a high level of correlation form a group. To maximize capacity, the low-dimensional exhaustive technique is utilized on each group to select the BS (base station) beamforming vector. Furthermore, a greedy approach is used, which takesinto account the influence of the earlier groups’ beamforming vectors. Simulation results display the system sum rate as the strong user dependent algorithm as complex than that of the existing grouping optimization HBF algorithm.

This paper proposes two models for Automatic Speaker Identification (ASI) task in the presence of interference. The first one uses the Normalized Pitch Frequency (NPF) and Mel- Frequency Cepstral Coefficients (MFCCs) as extracted features and multi-layer perceptron (MLP) as a classifier. In this model, we investigate the utilization of the Discrete Transform (DT) such as Discrete Wavelet Transform (DWT), Discrete Cosine Transform (DCT) and Discrete Sin Transform (DST) to increase the robustness of extracted features against different types of degradation through exploit the sub-band decomposition characteristics of DWT and the energy compaction property of DCT and DST. This achieved by extracting features directly from speech signal contaminated with features extracted from Discrete transformed signals to create a hybrid feature vectors. The enhancement techniques such as Spectral Subtraction (SS), Winer Filter (WF) and Adaptive Wiener Filter as a preprocessing stage to eliminate the effect of the interference on the ASI performance. In the second model, we investigate the using of Deep Learning (DL) based Convolutional Neural Network (CNN) with the spectrogram and the Radon transform to increase the robustness of the ASI against the interference effects. One of this paper goals is making comparison between two models and reach to more robust ASI system against severe interference. The experimental results indicates that the two proposed models articulate satisfying results, the model-based CNN consuming time is less than that based MLP which requires large training epochs and using many techniques for feature extraction and enhancing performance.

The development and introduction of AI language models have transformed the way humans and institutions interact with technology, enabling natural and intuitive communication between humans and machines. This paper conducts a competence-based analysis of an emerging AI language model’s task response to provide insight into its language proficiency, critical analysis and reasoning ability, and structure and relevance of the response. A multidisciplinary approach is adopted, drawing from fields such as Accounting, Education, Management, Social Work and Law, to evaluate the responses generated by the AI to higher education assignments. This paper offers insights into the strengths and limitations of language-based AI responses and identifies implications for the design and implementation of higher education assessments.

Design of RNA-based encryption schemes such as speed, security, and scalability utilize RNA molecules to encrypt and decrypt images in recent years. RNA-based encryption schemes have been proposed as a potential solution for secure communication. RNA molecules are used to encrypt messages, and the encrypted message can only be decoded using a complementary RNA sequence. In this paper, we propose a novel RNA-based encryption scheme that uses pixel depth to encode the RNA sequence. Our method employs the property of RNA sequences that their complementary sequences fold into specific shapes and assign each nucleotide in the RNA sequence a pixel value based on its location in the folded structure, and then use the pixel depth of these values to encode the message. We also demonstrate the effectiveness of the proposed method by encrypting and decrypting messages of varying length and complexity. Our approach is resistant to attacks based on frequency analysis, and it has potential applications in secure communication systems.
Female university students’ fertility intentions and their psychosocial factors: a cross-sectional survey in Nanjing, China

Background: With the demographic dividend diminishing at an accelerated rate, raising the fertility rate can successfully boost the ensuing labor supply and lessen the negative effects of an aging population on high-quality economic growth. Despite the ”three-child” policy that the Chinese government has implemented, the fertility rate is continually declining. This study aims to examine the current state of female university students’ fertility intentions and evaluate the level of feminist impact on those intentions. From there, it will explore the extent and pathways of the psychosocial factors’ influence on those intentions.
Methods: A cross-sectional survey of female university students was conducted in Nanjing, China, from February to March 2023. To assure the representativeness of the sample, a technique of stratified proportional sampling, PPS sampling, and convenience sampling was utilized. A total of 1124 valid samples were acquired from female university students in 15 comprehensive universities. The data were mined and analysed by SPSS (version 24.0) and AMOS (version 24.0) software.
Results: Overall female university students’ fertility intentions are low at this stage, with more than half (53.55%) of them having no clear desire to have children. The level of feminist identity significantly negatively affected the Intensity of desire to have children (-0.32) and child-number desires (-0.7). Psychosocial factors had a greater degree of influence on fertility intentions. The direct effect of the level of feminist identity and the perception of fertility hindrances on childbearing desires was -0.63 and -0.50 respectively, and the direct effect of the perception of fertility supports on childbearing intentions was 0.79.
Conclusion: The level of feminist identity is significantly and negatively related to childbearing desires. Psychosocial factors have a greater degree of influence on fertility intentions, with the level of feminist identity, the perception of fertility hindrances and the perception of fertility supports all significantly impacting fertility intentions. The findings of this study emphasise the importance of the government providing a full range of social security and employers providing better employee benefits to promote a fertility-friendly society.

Fertility is determined to a significant extent by its underlying genetics and success of pregnancy is considered as a tool to define fertility. A substantial knowledge gap exists however, regarding epigenetic abnormalities resulting in infertility. The accuracy of information concerning fertility is critical to the success of an infertility treatment plan. Here, the authors explore the use and the value of blood plasma small extracellular vesicle (sEV) derived micro-RNA (miRNA) as biomarkers of fertility. Next-generation miRNA sequencing identified 14 differentially expressed (DE) miRNAs expressed with a substantial confidence between low fertile (LF) sEV and high fertile (HF) sEV (FDR < 0.05 and -logFC > 2), isolated from plasma of dairy cows (n = 10 per each HF and LF group). Interestingly, the majority of DE miRNAs were uniquely packaged into sEV and not found in circulating plasma. Validation using qRT-PCR miRNA assays indicated similar expression patterns of miR-17-5p, miR-2285dd, miR-2335, miR-12054 and miR-2285aw, and confirmed that miR-181b-5p was significantly upregulated in LF sEV (P value = 0.0093, Fold change = 2.665). The results from this study suggest that circulating sEV miRNA reflect the overall fertility status including the physiological status of the endometrium. Moreover, miR-181b-5p was validated as a prognostic sEV miRNA biomarker of fertility.

In Jiaozuo mining area of North China coal field, there are multiple strong water-richness aquifers close to the coal seam. In order to prevent floor water inrush accident, it is need to be reinforced by floor grouting before mining. According to the changes of the mechanics and hydrogeological properties of the floor key rock strata after floor grouting, the coal seam floor is divided into ‘two zones’ of ‘water conduction fracture zone’ and ‘mechanical strength damage zone’. The composite water control model of ‘floor structure stability water control key layer’ and ‘floor damage infiltration water control key layer’ is established after grouting reinforcement of upper hard rock aquifer. Microseismic(MS) technology is used to analyse the characteristics of ‘two zones’ and the water control capability of ‘dual key layers’ in fault regions and no-fault regions respectively of experimental working face. It is revealed that the L8 limestone plays the role of mechanical barrier key layer after grouting. The change of elastic modulus of rock mass before and after grouting is measured by borehole ultrasonic method, which result shows that the elastic modulus of different rock mass increases by 40–852% respectively after grouting. By using the formula method, FLAC3D numerical simulation and field measurement, it is found that the failure depth of the floor after grouting is reduced by 51% compared with that without grouting. Seven influencing factors for floor water control ‘dual key layer’ are proposed, which are quantified by AHP (Analytic Hierarchy Process) method. A scheme of ‘dual key layer’ water control capability evaluation is formed by AHP method and influencing factors evaluation method. It is revealed that fault activation and fault with water-filling are the main factors that affect the failure of water control capability of ‘dual key layer’ and floor water inrush. The results of the research are consistent with the water inrush of the experimental working face, which will contribute to the early warning, prevention and evaluation of floor water inrush in mines with the same hydrogeological conditions.
