Authors: Ye Jianqiang , Guo Gaoxiang , Yu Kehong , Lu Yijuan
Published: June 2023

Background: The county is the basic unit of national economic and social development, and is also the foothold and starting point of public sports services. Purpose: Taking the top 100 economic counties of China in Zhejiang Province as the research object, this study explores the allocation efficiency and influencing factors of public sports resources in the period of 2016 to 2020. Methods: The output-oriented Super-SBM model, which is used to measure the static efficiency of its public sports resource allocation, is combined with the DEA–Malmquist model to measure the total factor productivity from the perspectives of overall characteristics, regional heterogeneity, and individual differences. Moreover, we objectively evaluate the dynamic evolution and spatiotemporal characteristics of resource quality growth, financial management technology, and allocation efficiency from the horizontal cross-section and vertical time series. Results: (1) The efficiency of allocation of public sports resources in the top 100 economic counties in Zhejiang Province is relatively high, but it presents the characteristics of “extensive” allocation, and the allocation structure is unreasonable. (2) The super-efficiency gradient division of public sports resources shows that Yuhuan City ranks first with a state of super-efficiency allocation; Ruian, Linhai, Wenling, Yiwu, and Haining have a state of high-efficiency allocation; and other regions are characterized by a state of medium- or low-efficiency allocation. (3) The improvement of total factor productivity depends on the catching-up feature of technological efficiency on the production frontier, but it has not yet compensated for the negative effect of the decline of technological progress, resulting in a decline in total factor productivity with an average annual trend of 0.3%. (4) The level of county economic development has a highly significant positive effect on the allocation efficiency of public sports resources, while the per capita sports ground area has a highly significant negative effect on efficiency. The county population density has a highly significant impact, and regional factors have no significant effect on efficiency. Conclusions: The results of this study provide useful insights for the development of sound public sports service improvement policies.

Published: June 2023

This paper evaluated the regional tourism competitiveness of 22 county-level administrative regions in Ningxia Hui Autonomous Region, China. The study analyzed the connotation of regional tourism competitiveness from the perspectives of resources and economic and environmental benefits, and established an evaluation index system for comprehensive competitiveness. The study used entropy weight TOPSIS to measure the level of tourism competitiveness in Ningxia, and used spatial association and hot and cold analysis to describe the spatial pattern of comprehensive tourism competitiveness in Ningxia. The results indicated that Lingwu City, Xixia District, and Huinong District have high comprehensive tourism competitiveness, while Jingyuan County, Haiyuan County, and Hongsipu District exhibit the weakest comprehensive competitiveness. The study also showed that regional economic development level competitiveness had the greatest impact on the comprehensive competitiveness of county tourism in Ningxia. The northern region and the southern region of Ningxia were the regions with high-high clusters and low-low clusters of tourism competitiveness, respectively. Based on the comprehensive evaluation results, the development level of tourism of Ningxia county was classified into four types: advanced development type, marginal dependence type, improved optimization type, and backward development type. Finally, the paper put forward targeted optimization suggestions in order to provide reference for Ningxia tourism functional zoning and high-quality development.

Published: June 2023

Background: The period of rapid transition from school to university is associated with a complex of negative stress factors caused by social and professional adaptation, irregular daily routine, sleep, and nutrition. During this period, the inclusion of functional foods in students’ diets has an increasingly beneficial effect on their health. This study aimed to evaluate the impact of diets with functional foods (vegetable and protein–vegetable) on health indicators while minimizing the negative impact of adaptation and acclimatization on the body of first-year university students at the start of their studies. Materials and Methods: A total of 150 first-year students were randomly selected. Biochemical tests, enzyme immunoassays, and analyses of serum immunoglobulin levels and mineral and vitamin content in first-year students’ blood were performed. Results and discussion: Protein–vegetable products are more potent compared to plant-based ones in increasing the body’s natural resistance to all types of stress due to their high protein content. The other functional product had a higher content of carbohydrates. In addition, they differed in the content of minerals and vitamins. Conclusions: The importance of a rational diet increases exponentially during the period of adaptation and acclimatization when the emotional, mental, and physical workload increases.

Published: June 2023

Eco-efficiency is a significant target for evaluating the agricultural ecosystem and measuring sustainable agricultural development through quantitative analysis. It is also an essential part of constructing the ecological tea garden, which offers a directional function in realizing the green development of the tea industry. After measuring the eco-efficiency of China’s tea industry using the super-efficiency SBM model, this paper analyzes the spatial disequilibrium and dynamic evolution trend of the eco-efficiency in China’s tea industry through the method of Dagum Gini Coefficient and Kernel Density Estimation. The results show that the level of eco-efficiency in China’s tea industry was improved overall, and the spatial disequilibrium was significantly reduced. The differences within the tea region decreased as follows: tea regions in Southwest China, South China, south of the Yangtze River, and north of the Yangtze River; the overall difference in the eco-efficiency in the tea industry mainly comes from the contribution of the interregional difference in tea regions, and the second contribution comes from the intraregional difference in tea regions and the difference in super-variable density. The eco-efficiency of the tea industry has been improved both nationally and within the top four tea regions; the disequilibrium between areas and within the tea region has been largely alleviated, but there is still room to optimize the input–output structure and promote the eco-efficiency.

Published: June 2023

Conventional organic soil amendments and drip irrigation are insufficient for mitigating soil salinization. The development of a more potent soil amendment with higher water retention capability is critical. Carboxymethyl cellulose (CMC) has excellent water retention and adsorption properties and is suitable for soil water retention and amendment; however, its effects on water and salt distribution, soil nutrients, and maize yield have not been clearly investigated. We set up five treatments with flood irrigation (CK), drip irrigation (W), drip irrigation combined with 100 kg CMC ha−1 (WC1), drip irrigation combined with 200 kg CMC ha−1 (WC2), and drip irrigation combined with 300 kg CMC ha−1 (WC3). Our findings demonstrate that the application of CMC in conjunction with drip irrigation led to a significant surge in soil water content within the 0–40 cm layer, ranging from 3.73% to 16.46%, while simultaneously inducing a reduction in salt content of 4.08% to 16.61%. Consequently, this resulted in a desalination rate spanning from 10.32% to 12.93%. The salt was gradually washed down and formed a desalination area with the drip emitter as the center, and the salt distribution characteristics shifted from a surface accumulation type to a bottom deposition type. The drip irrigation and CMC application also increased the content of available nutrients, reduced surface evaporation, underground water loss, and maize evapotranspiration, and improved water-use efficiency, thus increasing the aboveground biomass and grain yield. In summary, CMC had a significant effect on water retention, desalination, and yield increases. It can serve as a novel soil amendment for salt-affected soil.

This study examined the willingness-to-pay (WTP) of consumers and the determinants of eco-labeling for the organic cocoa powder produced in the Dong Nai UNESCO Biosphere Reserve (DNBR), Southern Vietnam. Eco-labels are designed according to the tiers of eco-labeling for biosphere reserves (BR) introduced by UNESCO; they include BR Destination (Tier 1), BR Quality (Tier 2), and Professional Certification (Tier 3) labels. Questionnaires were delivered to 203 customers in the DNBR and nearby places, such as Dong Nai and HCMC. This study employed a hybrid approach using descriptive statistics, an ANOVA test, and a Partial Least Squares Structural Equation Model (PLS-SEM). The results indicate that gender and educational level have a positive effect on consumers’ preferences. Customers are willing to pay more for cocoa powder with an eco-label than one with an organic label. Perceived food safety and product knowledge lower customers’ WTP, whereas agricultural environment and pricing concerns increase it. Tier 2 is suggested for labeling cocoa powder in the DNBR. The DNBR Management Board, together with the federal and provincial governments, should all follow a similar certification process. Increased eco-label awareness is crucial for the future of environmentally responsible shopping and responsible business practices.

Published: June 2023

In this manuscript, we studied a wideband metasurface-based terahertz (THz) absorber. The metasurface of the proposed absorber was comprised of fan-like periodic resonators made of nickel (Ni). The absorptivity of the proposed absorber was analyzed from 3.5 to 5 THz. The wideband absorptivity is observed with an absorption above 75% from 3.7 to 4.7 THz. The polarization-insensitive behavior of the absorber is depicted due to the symmetric nature of the top metasurface. The absorption feature was also analyzed for the transverse electric (TE) and transverse magnetic (TM) operating modes for the obliquity of the incidence wave. The surface current density shows that absorption is achieved due to the electric resonance of the proposed absorber. The proposed absorber would be useful for several applied areas covering medical science, communication, safety supervision, chemical sensing, and imaging.
Molecular Dynamics Simulation from Symmetry Breaking Changing to Asymmetrical Phospholipid Membranes Due to Variable Capacitors during Resonance with Helical Proteins
Authors: Thi Dang Dung , Monajjemi Majid , Mollaamin Fatemeh , Dang Chien
Published: June 2023

Biological symmetry breaking is a mechanism in biosystems that is necessary for human survival, and depends on chemical physics concepts at both microscopic and macroscopic scales. In this work, we present a few mechanisms of the signaling phenomenon that have been studied in various tissues of human origin. We exhibit that anatomical asymmetry in the structure of a membrane can produce a flow of extracellular fluid. Furthermore, we exhibit that membrane asymmetry is a misbalance in the composition of the aqueous phases and interaction forces with the protein trans-membrane. Various biological membranes such as DPPC, DMPC, DLPC, and so on, have considerable electrostatic voltages that extend across the phosphor lipids bilayer. For studying these phenomena, we modeled DPPC, DMPC, and DLPC lipid bilayers with a net charge misbalance across the phospholipids. Because asymmetric membranes create the shifted voltages among the various aqueous tissues, this effect makes the charge misbalances cause a voltage of 1.3 V across the DPPC bilayer and 0.8 V across the DMPC bilayer. This subject exhibits the importance of membrane structures on electrostatic potential gradients. Finally, we exhibited that a quantum effect was created in small parts of the cell’s thickness due to the symmetry breaking of asymmetrical phospholipid bilayers.
Coordinated Symmetrical Altitude Position and Attitude Control for Stratospheric Airship Subject to Strong Aerodynamic Uncertainties
Authors: Yan Kun , Jiang Ju , Sun Mingwei , Chen Zengqiang
Published: June 2023

The stratospheric airship has important value in both commercial and military use. The altitude position control is very crucial for the airship to conduct specific missions, which is also a challenge because of both the severe relative aerodynamic mismatches and the large lag due to the quite low speed of the airship within 15 m/s. In this paper, a coordinated altitude and attitude control method was proposed to realize satisfactory altitude position control while maintaining the attitude stability by properly employing the two actuators, the propeller thrust and the elevator, in a consistent manner. In this process, the references for the vertical speed and the pitch were specified in a straightforward way of proportionating them by considering their physical characteristics and the inherent symmetrical relationship between them, which can be obtained through the kinematics. An extended disturbance observer was used to eliminate the severe aerodynamic uncertainties to symmetrically distribute the two actuator outputs by dynamically decoupling the vertical speed and the pitch angular rate loops into the two independent integrators. As a result, the explicit proportional controllers were sufficient to realize efficient command tracking. Rigorous theoretical investigation was provided to symmetrically prove the quantitative bounded property of the estimation and tracking errors. The simulation results demonstrated the effectiveness of the proposed approach, which can realize a 500-m altitude difference tracking within 200 s with less than 0.5 deg/s pitch angular rate.

Published: June 2023

Atropisomers, i.e., stereoisomers that are distinct because their free rotation about a single bond is hindered by steric interactions between nearby bulky groups or by electrostatics, may interact with their surroundings in different ways, and may also exhibit different properties. They may be found as natural products, as pharmaceutical or agricultural active ingredients, as chiral ligands and organocatalysts, and in functional materials. Our ability to synthesize them stereoselectively and in a sustainable way, using achiral materials and simply with the aid of an organocatalyst and mild conditions, has become a hot topic in research. This review provides an overview of recent achievements in the synthesis of atropisomers containing C-N and N-N axes of chirality.

This article examined the characteristics of zeolites from the Chankanai and Daubabinsk deposits. In the field of water treatment, the purpose of investigating natural zeolite from the Chankanai and Daubabinsk deposits as a sorbent presents new opportunities and prospects, as this raw material is little studied. The effectiveness of the sorbents was assessed based on the results of the water specifications according to the following criteria: methods for determining the total hardness of water; methods for measuring the mass concentration of total iron in water; methods for the determination of chloride in water; methods for the determination of nitrogen-containing substances in water; methods for determining the dry residue content of water; methods for determining the sulphate content of water; on hygiene requirements and water quality control. Zeolite modifications were aimed at improving their adsorption properties, increasing the efficiency of pollutant removal and developing optimal methods of using zeolites in water filtration. Modified zeolite from the Chankanai and Daubabinsk deposits showed high efficiency as a filter. When it was used to treat natural water, which normally contains high hardness and alkalinity, the best results were achieved with zeolite from the Chankanai deposit. In terms of Fe+ and Cl content, the best results were achieved using zeolite from the Daubabinsk deposit.

Published: June 2023

State and federal agencies regulate fecal indicator bacteria (FIB), such as E. coli or Enterococcus, in order to manage public health risks at swimming beaches. Despite these goals, watershed managers are challenged in terms of how to best clean up sources of FIB because concentrations frequently exceed water quality objectives, and sources—both human and nonhuman sources of FIB—appear to be everywhere. Since most nonhuman fecal sources represent substantially lower public health risks than human sources do, this study utilizes the human fecal source marker HF183 to better define watershed managers’ riskiest sites and times in order to prioritize remediation actions. A total of 117 samples were collected and analyzed for both FIB and HF183 from 26 sites during multiple sampling campaigns between 2019 and 2021 along the mainstem in addition to major tributaries in a highly urbanized watershed. The results indicated that the vast majority of samples (96%) quantified HF183 during wet weather, ranging from 99 to 44,768 gene copies/100 mL. Similar to HF183, the FIB results exceeded water quality objectives for 100% of the samples in wet weather; however, HF183 was rarely quantified in dry weather, with 3 of 72 samples (4%) exceeding 500 gene copies/100 mL, while two-thirds of samples (67%) exceeded FIB water quality objectives during dry weather. Where HF183 was detected in dry weather, isolated and unpredictable events explained human fecal pollution. It is more challenging in wet weather to identify and quantify the source(s) of human fecal pollution.

Authors: Redinova T. L. , Chikurova N. V. , Gubaeva V. R.
Published: June 2023

Relevance. According to the latest international classification of periodontal diseases of 2018, smoking, along with diabetes mellitus, belongs to the main modifying factors of the periodontitis course. At the same time, the clinical signs of gingival inflammation in smokers are not very pronounced.

The study aimed to determine significant clinical indicators of gingival inflammation in tobacco-dependent peri- odontal patients.

Materials and methods. The study interviewed and examined 82 patients with generalized periodontitis aged 20 to 63 years. Patients with diabetes mellitus were excluded. The examination evaluated the caries prevalence (DMFT index), the degree of periodontal attachment loss, the periodontitis progression type by an indirect indicator, oral hygiene status (Green-Vermilion index), tooth mobility (D.A. Entin), bleeding on probing (Mühlemann modified by Cowell; Ainamo, Wow). Based on their attitude to smoking, patients were randomized into three groups: the first group consisted of 18 patients who smoked up to 10 cigarettes per day; the second group included 15 patients who smoked 10-20 or more cigarettes per day; and the third group (comparison group) consisted of 18 non-smokers.

Results. The oral hygiene status, caries prevalence, the number of extracted teeth, the mobility of remaining teeth and the bleeding on probing score appeared to be the same in non-smoking and smoking periodontal patients. However, the number of patients with severe periodontitis was statistically significantly higher in heavy smokers with periodontitis (more than ten cigarettes per day); every other patient had comorbidity, rapid progression of the disease, and the clinical indicator of gingival inflammation based on the prevalence of bleeding on probing was at 100%.

Conclusion. We believe that the prevalence of bleeding on probing should be the main parameter for gingival inflammation assessment in smokers, which allows for the objective follow-up of the process progression in such patients and motivation for treatment and smoking cessation.

Published: June 2023

Relevance. The work presents the results of a comprehensive dental examination of patients with vermilion and oral mucosa proper (OM) diseases associated with manifestations of Crohn's disease (CD) and ulcerative colitis (UC).

Aim. To determine the cause-related features of complaints and clinical manifestations of vermilion and OM diseases.

Material and methods. The comprehensive dental examination included the analysis of complaints, history, and assessment of the vermilion and OM condition and the nociceptive pain severity score according to the Visual Analog Scale (VAS).

Results and discussion. In CD and UC, the vermillion diseases clinically manifested in 51.43% and 42.85% of subjects (p < 0.01), OM chronic trauma – in 40.0% and 31.43% (p < 0.05), chronic recurrent aphthae – in 48.47% (p < 0.001) and 31.43% (p < 0.01), glossitis – in 62.86% (p < 0.001) and 25.71% (p < 0.01), glossodynia – in 31.43% (p < 0.01) and 17.15% (p < 0.05) of cases. The main complaints of patients with the detected OM pathology included unpleasant sensations, like rawness and soreness, on taking irritating foods in 100% and 65.71% and talking in 31.43% and 25.71% of cases, dry mouth in 51.43% and 25.71% of cases. The burning mouth syndrome was in 31.43% and 17.15% of patients.

Conclusion. The vermilion and the oral mucosal diseases often prevail associated with the clinical course of Crohn'sdisease compared to patients with UC. The VAS pain severity score hinges on CD and UC course (p < 0.055). The variety of clinical manifestations of the vermillion and oral mucosal diseases directly depends on CD and UC, a criterion for developing an integrated approach to their diagnosis and implementing recommendations for their prevention and treatment in practical health care.

Relevance. The issue of oral mucosa and bone tissue restoration after tooth extraction and other dental interventions determines the study's relevance. The article presents experimental study results of regeneration processes in the animal oral mucosa and bone tissue wound surface during two operations: tooth extraction without bone structure and material grafting and tooth extraction with autologous dental tissue grafting.

Material and methods. The study included 24 laboratory male Wistar rats divided into two groups. The animals of the main group underwent tooth extraction followed by simultaneous autologous tissue grafting into the extracted tooth socket. The autograft consisted of the tissues of a particulated tooth previously removed from the subject. Animals of the control group underwent tooth extraction without bone structures and material grafting.

Results. On day 21, all study groups showed complete oral mucosa regeneration in the extracted tooth area. After 1.5 months of control group observation, the socket floor was filled with mature granulation tissue, transforming into fibrous tissue. The main study group demonstrated bone formation by autograft replacement in the coarse fibrous tissue growth thickness. After three months of observation, the control group showed bone atrophy at the extracted tooth site. In the main study group, there was newly formed bone tissue, which had replaced the autograft.

Conclusion. The conducted experimental study demonstrates that autologous particulated dental tissue grafting leads to active new bone formation, which the histology results confirmed in 21 days, 1.5 and 3 months of followup observation.

Published: June 2023

Relevance. Gum recession is a pathology often encountered both in Russia and worldwide. Modern surgical methods allow for the complete elimination of recession signs when adequately choosing strategy, tactics, methodology and surgical treatment protocol; for complication prevention and stable long-term outcome. Autograft and allogeneic dura mater as a grafting material for creating/increasing the volume of the attached gingiva in recession treatment have comparable results in all clinical indications. The reason for result stability and the absence of relapse is poorly studied; the data are scarce and do not give a full understanding. In the scientific literature, we did not encounter histological tissue composition analysis in the graft placement area. In recession coverage, the graft is partially placed subperiosteally (in the tooth root area) and partially in the thickness of the soft tissues of the gum. Purpose. The study aimed to determine the histological composition of tissues in the dura mater placement area, to compare with the control group without a graft, and to assess follow-up changes in the graft and surrounding tissue reaction as a result of cellular-level surgery.

Material and methods. A laboratory histomorphological examination involved 60 laboratory rats. All underwent surgery adequate to gum recession surgical treatment technique: the control group had no graft, and the study group had allogeneic dura mater. The samples were collected on the 3rd, 7th, 14th, 28th, 90th and 107th days after surgery.

Results. In all cases, the tissue complex regenerated, and the reaction to the operation was the same. The plastic material replacement was at the same period. Bone tissue replaced subperiosteally placed graft, connective tissue intragingivally. Gingival biotype thickening was considerably due to the surgical trauma, less – from the graft material. Allogeneic dura mater stimulated earlier ossification.

Conclusion. In all cases, the use of grafting material for surgical gum recession coverage is justified if placed subperiosteally, forming a full-thickness mucoperiosteal flap surgically (with a scalpel) to preserve the cambium periosteum on the flap. Bone volume and buccal cortical plate reconstruction/ regeneration support soft tissues of the newly formed ligament of the tooth and prevent recurrent recession formation. The formation of bone and connective tissues in the dura mater placement area determines the result stability of gingival recession surgical treatment and a long-term favourable prognosis without complications and relapse.

Authors: Ling Jiying , Zahry Nagwan , Stommel Manfred , Horodynski Mildred
Published: June 2023

Healthful dietary intakes are crucial for stemming the current childhood obesity epidemic. We examined the dietary intakes of 392 Michigan children aged 1–12 years. About 70% and 58% of children ate fruits and vegetables, respectively, each day; 26% drank sugar-sweetened beverages; and 31% ate with a television on. Children's vegetable intakes were significantly and moderately correlated with their parents' vegetable intakes (r = .34–.38), but their fruit intakes were more related to their grandparents' fruit intakes (r = .31). Due to the relative representativeness of our sample and similarities in eating patterns across the region, Extension professionals may consider our study findings when designing tailored nutrition education programs for families in the midwestern United States.

Authors: Chlipalski Micheline , Quick Don , Auld Garry , Baker Susan
Published: June 2023

We conducted a needs assessment prior to development of an online training for paraprofessionals in the Expanded Food and Nutrition Education Program. Through interviews with Extension professionals and paraprofessionals from three Extension regions, we determined characteristics of paraprofessionals' existing training environments and the paraprofessionals' characteristics as learners. Interviewees supported the development and implementation of an online training and identified benefits related to online training. Paraprofessionals expressed preference for a video-based rather than text-based format and wanted the training to complement not replace face-to-face training. Our findings may be useful in supporting the development of effective online training that meets the needs of other Extension initiatives.

Surfing Information: The Challenge of Intelligent Decision-Making
Authors: Wu Chenyang , Zhang Zongzhang
Published: June 2023

Reinforcement learning (RL) is indispensable for building intelligent decision-making agents. However, current RL algorithms suffer from statistical and computational inefficiencies that render them useless in most real-world applications. We argue that high-value information in the real world is essential for intelligent decision-making; however, it is not addressed by most RL formalisms. Through a closer investigation of high-value information, it becomes evident that, to exploit high-value information, there is a need to formalize intelligent decision-making as bounded-optimal lifelong RL. Thus, the challenge of achieving intelligent decision-making is summarized as effectively surfing information, specifically regarding handling the non-IID (independent and identically distributed) information stream while operating with limited resources. This study discusses the design of an intelligent decision-making agent and examines its primary challenges, which are (a) online learning for non-IID data streams, (b) efficient reasoning with limited resources, and (c) the exploration–exploitation dilemma. We review relevant problems and research in the field of RL literature and conclude that current RL methods are insufficient to address these challenges. We propose that an agent capable of overcoming these challenges could effectively surf the information overload in the real world and achieve sample- and compute-efficient intelligent decision-making.

Published: June 2023

Recollision physics and attosecond pulse generation meld the precision of optics with collision physics. As a follow-up to our previous work, we reveal a new direction for the study of electronic structure and multielectron dynamics by exploiting the collision-physics nature of recollision. We show experimentally that, by perturbing recollision trajectories with an infrared field, photorecombination time delays can be measured entirely optically using the Cooper minimum in argon as an example. In doing so, we demonstrate the relationship between recollision trajectories and the transition moment coupling the ground and continuum states. In particular, we show that recollision trajectories are influenced by their parent ion, while it is commonly assumed they are not. Our work paves the way for the entirely optical measurement of ultrafast electron dynamics and photorecombination delays due to electronic structure, multielectron interaction, and strong-field-driven dynamics in complex molecular systems and correlated solid-state systems.

Introduction: Breast cancer is one of the most common cancers in women. Involvement of regional lymph nodes by breast cancer has shown to be a significant marker in the overall diagnosis of patients. In this study, we aimed to investigate the role of gray-scale ultrasound and elastography in discriminating benign from malignant axillary lymph nodes in patients with breast cancer. Methods: In this analytical study, patients with breast cancer who were referred to sonography ward of a tertiary medical educational center and found to have suspicious lymph nodes were investigated. Formal properties were evaluated by grayscale ultrasound and tissue properties were assessed by elastography. Biopsies were performed on all cases and suspicious tissues were removed. Results: This study was conducted on 50 patients with the mean age of 48.54±10.58 years. 52% of patients had a mass in their right breast and the most prevalent type of breast cancer was intra-ductal carcinoma. 60% of the lymph nodes were reported to be malignant. In 56% of the lymph nodes, grayscale ultrasound tests demonstrated unusual findings and the most common finding was the removal of fat from lymph node hilum. Moreover, elastography results indicated that 36% of the cases have grade 4 (blue) lesions. Conclusion: This study indicated that grayscale ultrasound and elastography have high sensitivity and specificity in detecting metastatic lymph nodes. This finding was in line with the findings reported in many of the previous studies.

Introduction: Although there are many forms of education, learning by doing is one of the most efficient ways of learning in the field of medicine. In Turkey, intern doctors can perform and observe many emergency interventions in the presence of supervisors during their emergency service internship. This study aimed to examine whether intern doctors have developed the necessary emergency response skills concerning some vital situations after emergency medicine internship involving their applied training and observation. Methods: This prospective cross-sectional study was conducted between June 2, 2022, and September 1, 2022, in the emergency department of a tertiary hospital. In the study, the emergency response skills of intern doctors were measured with a questionnaire prepared using scenarios in which emergency situations were described. Results: The participants’ emergency response skills were improved in the most of emergencies described in the questionnaire. However, there was no significant improvement in emergency intervention skills related to the approach to ventricular tachycardia and multi-trauma patients (P=0.771 and P=0.45, respectively). Conclusion: Doctors doing internship in the emergency medicine clinic receive both theoretical and applied training, which increase their ability to respond to emergency situations. However, there is a need to identify emergency situations in which internship training does not sufficiently improve intervention skills and try new methods to improve the related skills.

Introduction: Kidney dysfunction, coagulopathy disorders, and lung involvement are the most common disorders caused by the COVID-19 virus. Objectives: This study aimed to investigate the correlation of lung involvement severity with kidney dysfunction and coagulopathy disorders in COVID-19 patients. Patients and Methods: This descriptive-analytical study was conducted on 97 patients with COVID-19 referred to Imam Reza hospital in Kermanshah from December 2020 to June 2021. Lung involvement severity, kidney function tests, and coagulation laboratory data were collected. Logistic regression test was conducted to explore the correlation between lung involvement with kidney dysfunction and coagulopathy disorders. Results: Out of 97 patients, 53 (54.6%) were male, with a mean age of 59.31 ± 16.44 years. The correlation between lung involvement severity with kidney function tests, including, blood urea nitrogen, serum creatinine, and coagulation factors, including prothrombin time (PT), partial thromboplastin time (PTT), and D-dimer, were significant (P > 0.05). Lung involvement severity significantly predicted kidney dysfunction and coagulopathy disorders. Conclusion: Lung involvement severity would be able to predict kidney dysfunction and coagulopathy disorders in patients with COVID-19.

Background. The birth of a premature baby needing to be hospitalized in the neonatal intensive care unit (NICU) endangers the initial mother-baby relationship, affecting mother-baby attachment. Therefore, it seems necessary to provide mothers of premature babies with appropriate nursing support. In the present study, we aimed to investigate the effects of spiritual self-care training on the mother-baby attachment of mothers giving birth to premature babies hospitalized in the NICU. Methods. This was a semi-experimental study with pre-test/post-test design conducted on 60 mothers with babies admitted to the NICU of Taleghani Hospital of Ilam (30 participants in each of the intervention and control groups).Two questionnaires were used for data collection, including a demographic information questionnaire and the Maternal Postnatal Attachment Scale (MPAS). Five self-care training sessions (45 minutes each) were held for mothers of the intervention group according to a self-care booklet prepared by the researcher. The attachment questionnaire was again completed after one week of the last training sessions by all participants, and the data were analyzed using SPSS version 22 software. Descriptive statistics were used to present quantitative (mean ±SD) and qualitative (frequency, %) variables. The normality of the data was checked using the Kolmogorov Smirnov test, and the MANOVA and univariate analysis of covariance (ANCOVA) tests were used to investigate the effects of the training on mother-baby attachment. The statistical significance level was considered P<0.05. Results. The means of the total attachment score in the intervention and control groups were obtained as 51.73 and 56.43 at the pretest and 53.36 and 49.77 at the post-test, respectively, indicating that spiritual self-care training was effective in improving mother-baby attachment (P<0.05). Conclusion. Our results showed that spiritual self-care training augmented mothers’ attachment to their babies hospitalized at the NICU. According to the results of the present study, it is suggested to pave the ground in clinical environments by educating nurses and caregivers and supporting the mother and the baby through spiritual self-care interventions to promote maternal attachment and improve their conditions. Practical Implications. According to the results of the present study, it is suggested to pave the ground in clinical environments by educating nurses and caregivers and supporting the mother and the baby through spiritual self-care interventions to promote maternal attachment and improve their conditions.

Background. Organizational socialization is a process of teaching employees to successfully integrate into a new organization. Socialization needs to be presented in the form of a coherent pattern. Methods. This study aimed to design a model for the organizational socialization of employees in Iran’s healthcare system using the grounded theory method. Semi-structured interviews were used to extract the main factors influencing the socialization of employees. In-depth interviews were conducted with 19 experts, including specialists, managers, and employees of the healthcare system using the purposeful sampling method. We extracted 49 concepts and 19 categories using the foundation data method in the open coding stage. Results. The findings showed that developing a model for organizational socialization in Iran's banking system requires the senior managers’ constant support, social responsibility, and socializing organizational culture. The values, norms, and roles expected from the individual should be transmitted clearly. Conclusion. An organizational socialization model can enhance the socialization of employees in Iran’s healthcare system. Practical Implications. The development of socialized human resources, socialized competitiveness, and socialized basic management requires the Bdesign of socialized human resources processes, an evaluation system, a resource allocation system, socializing succession, and value creation.
