Shedding Light on the Effects of Orienteering Exercise on Spatial Memory Performance in College Students of Different Genders: An fNIRS Study

Objective: To investigate the intervention effect of orienteering exercises on the spatial memory ability of college students of different genders and its underlying mechanism. Methods: Forty-eight college students were randomly screened into experimental and control groups, 12 each of male and female, by SBSOD scale. The effects of 12 weeks of orienteering exercises on the behavioral performance and brain activation patterns during the spatial memory tasks of college students of different genders were explored by behavioral tests and the fNIRS technique. Results: After the orienteering exercise intervention in the experimental group, the male students had significantly greater correct rates and significantly lower reaction times than the female students; left and right dorsolateral prefrontal activation was significantly reduced in the experimental group, and the male students had a significantly greater reduction in the left dorsolateral prefrontal than the female students. The degree of activation in the left and right dorsolateral prefrontals of the male students and the right dorsolateral prefrontals of the female students correlated significantly with behavioral performance, and the functional coupling between the brain regions showed an enhanced performance. Discussion: Orienteering exercises improve the spatial memory ability of college students, more significantly in male students. The degree of activation of different brain regions correlated with behavioral performance and showed some gender differences.
Role of Additive Manufacturing in Development of Forming Tools and Dies for Sheet Metal Forming: A Review

Price and time are two major concerns in the industry which encourages the development and manufacturing of new dies for sheet metal forming applications. Additive manufacturing (AM) and rapid tooling (RT) are now emerging techniques for producing cost-effective and fast production of sheet metal forming dies with excellent mechanical and wear resistance properties. The paper gives an insight into AM processes that were implemented in the tooling industry to enhance moulding efficiency and sheet metal forming processes. The advantages and challenges observed in using AM are highlighted and discussed as opposed to traditional tooling. The RT processes used in moulding and sheet metal formation are addressed, and their limitations are highlighted. The paper also discusses several possible application areas in which AM technologies can be used further to enhance the efficiency of the devices. Finally, discussion on current issues related to the use of AM in tooling has been presented.
COMPARATIVE STUDY ON PHYSICOCHEMICAL CHARACTERISTICS OF CASSAVA ROOTS FROM THREE LOCAL CULTIVARS IN CÔTE D'IVOIRE

This study was aimed to characterize three local cassava cultivars (Akaman, Yace and Zoklo) commonly used and to compare their physicochemical characteristics in order to choose the right roots for the suitable usages. For this purpose, the moisture, ash, starch, protein, lipid, titratable acidity, pH, cyanide, total sugar, carbohydrate, caloric energy, minerals (Ca, Mg, Zn, Fe and P) contents and the Ca/P ratio of roots were evaluated. Data obtained were subjected to chemometric methods (Analysis of variance, Multidimensional Analysis of variance and Cluster analysis). The results showed that roots analyzed had the same general characteristics, whatever the cassava cultivar. Their moisture (60.36-62.18%), energy (385.93-388.63 kcal/100 g), starch (75.36-77.70%) and carbohydrate (92.5293.65%) contents were high while the protein (1.95-2.27%), lipid (0.581.04%), ash (2.29-2.67%) and total sugar (2.10-2.64%) contents were low. The significant differences (p<0.05) between the three cassava cultivars were on the physicochemical parameters such as pH, titratable acidity, lipid, cyanide, total sugar and carbohydrate contents. The roots from Yace cultivar are toxic variety and must be processed into various products before consumption. They were characterized by high titratable acidity and carbohydrate, low pH value and total sugar content. The roots from Zoklo European Scientific Journal November 2014 edition vol.10, No.33 ISSN: 1857 – 7881 (Print) e ISSN 18577431 419 cultivar are non-toxic and can be eaten directly, either raw or boiled, or can be processed into various products before consumption. The Akaman roots, characterized by their relatively high lipid content, were intermediate variety and must be processed in order to avoid farther poisoning. Attention must be focused on their utilization form, avoiding consumption as raw.
A New Non-Isolated Low-Power Inductorless Piezoelectric DC–DC Converter

We present a new non-isolated low-power inductorless piezoelectric resonant converter. The piezoelectric material is used as an energy storage element like an inductance in a classical buck–boost power electronic converter. As opposed to most existing piezoelectric converters, the proposed topology enables to dynamically adjust the output power and ratio keeping a high efficiency for a large range of output powers and for a large range of conversion ratios taking advantage of piezoelectric high-quality factor and achieving zero-voltage switching. A theoretical analysis of the step-up converter using an energetic approach is introduced and enables a fast and reliable predesign of the piezoelectric component. This analysis is in perfect agreement with the simulation model performed on MATLAB/Simulink. For a given piezoelectric resonator both analytical and simulation models provide very high efficiencies for different output powers. The converter is tested experimentally with a 10 V input voltage using the piezoelectric radial resonance mode. An efficiency higher than 98% for a 160 mW power conversion is achieved, decreasing slowly to 78% at 1.4 W. For a large range of voltage gains, the efficiency remains higher than 90% up to an output power of 750 mW. The experimental results are in perfect agreement with the theoretical analysis until 500 mW.
The training of researchers in the use of statistics in China

The responsibility of training researchers in the use of statistics in China belongs to colleges, universities and research institutes. There is a National Statistical Education Association. Under the Association, the Higher Education Branch is an organisation of colleges, universities and research institutes who have a major in statistics or a statistics faculty. Since China has a population of 1.25 billion and more than 100 thousand official statisticians in the whole country, statistics training is a huge task. There are degree and non-degree training programs. In the degree program, there are undergraduate programs (colleges and universities) and graduate programs (colleges, universities and research institutes). In the non-degree training, different training programs have been used. Statistical methods are widely used in almost all the fields. The most important application areas are: official statistical work including sampling survey and data processing, micro-economic analysis, management and quality improvement, medical application, agriculture and industry experiment, etc. Most researchers in the above fields need to be trained. Many patterns have been used in training. Class teaching, group discussion, field training, TV, broadcasting programs and Internet are the main patterns.
THE PERCEPTION OF CONSUMERS ON MUSLIM FASHION BRAND IN INDONESIA

Muslim clothing is the way Muslim women wear their clothes according to Islamic law, namely clothing that is not tight (shaping the curves of the body) and the user of the clothing is a Muslim woman who is obedient to the teachings of her religion in dress procedures. Currently, Muslim clothing is a concern among the clothing industry in Indonesia. In its development, the brand of Muslim clothing has also become one of the consumer's assessments or perceptions of a product. A good brand is one of the assets for the company because the brand has an impact on every consumer perception, where the public will have a positive impression of the product and the company. The purpose of this study is to describe how Indonesian consumers perceive Muslim fashion brands. The type of research used is qualitative research using library research methods. Sources of data used in this study are primary and secondary data sources. While the data analysis technique used in this research is content analysis. The results of this study indicate that brands are extrinsic stimuli that affect consumer perceptions of a product.
Delta Opioid Receptors and Enkephalinergic Signaling within Locus Coeruleus Promote Stress Resilience

The noradrenergic nucleus locus coeruleus is a key component of the stress circuitry of the brain. During stress, the neuropeptide corticotropin-releasing factor (CRF) is secreted onto LC, increasing LC output and norepinephrine concentration in the brain, which is thought to promote anxiety-like behavior. LC is also innervated by several structures that synthesize and release the endogenous opioid peptide enkephalin onto LC upon stressor termination. While the role of CRF neurotransmission within LC in mediating anxiety-like behavior and the behavioral response to stress has been well characterized, the role of enkephalinergic signaling at LC-expressed δ-opioid receptors has been comparatively understudied. We have previously shown that acute stressor exposure increases LC activity and anxiety-like behavior for at least one week. Here, we extend these findings by showing that these effects may be mediated at least in part through stress-induced downregulation of DORs within LC. Furthermore, overexpression of DORs in LC blocks the effects of stress on both LC firing properties and anxiety-like behavior. In addition, intra-LC infusions of enkephalin blocked stress-induced freezing behavior and promoted conditioned place preference. These findings indicate that enkephalinergic neurotransmission at DORs within LC is an important component of the behavioral response to stress and may drive reward-related behavior as well.
“The pandemic of distance learning”: How Arab high school students see online‐learning during Covid‐19

Abstract Emergency transition to online due to the coronavirus disease 2019 (Covid‐19) pandemic has created unprecedented challenges in schooling. There is a dearth of information on the perception of Arab high school students and parents regarding the negative effects of online learning during Covid‐19. Qualitative analysis of data from a multisite ethnographic‐centered study collected in nine Arab countries. Data presented are only the ones recorded from students and parents. Raw data were abstracted using a mind‐mapping software and coded using words. The perceived negative effects of students and parents on several aspects of the transition to online learning such as the needed technical adjustments, impact on parents, perceptions of learning online versus face to face, pedagogical drawbacks, and psychological effects are described and discussed in light of results of previous studies. In spite of cultural differences, Arab high school students and parents face the same challenges and difficulties reported in other parts of the world. The overarching theme that emerges both for parents and children is the perceived superiority of face‐to‐face learning in the structured environment of the school for a more holistic learning and socialization experience of students and for better long‐term outcomes.
Relationship between Maternal Touch, Maternal Self-Confidence, Infant Length, and Feeding Volume in High-Risk Infants: Touch on the Mind

Background: Childbirth is a physical and emotional experience. In particular, mothers of high-risk infants often exhibit low maternal self-confidence. Through interactions in the form of touch, maternal sensory stimulation provides comfort for both mother and baby. This study aims to investigate the association between maternal touch in the early postpartum period and the growth of infants as well as maternal self-confidence.Methods: Thirty-six mother-infant dyads in a level III-IV Neonatal Intensive Care Unit (NICU) were analyzed. Maternal touch on various body parts (extremities, face/head, and trunk) was observed, and infant length and feeding volume were assessed by direct measurement of the medical records. Maternal self-confidence was assessed using a questionnaire. Along with descriptive statistics, we conducted correlation and Mann-Whitney U tests.Results: Although maternal self-confidence decreased over time, that of mothers with a high level of contact with the infant’s face/head or extremities decreased significantly less than that of mothers in the low-contact group. For the baby, the feeding volume of infants with a high degree of maternal contact on their extremities or trunk increased significantly compared with that of the low-contact group.Conclusions: Mothers’ self-confidence may not improve as the infant grows, but can be strengthened by enhanced touch on the infant’s face/head. Touching the infant’s trunk is related to infant feeding. The research findings emphasize the importance of early maternal touch in the NICU environment and recommend the provision of maternal touch to appropriate body parts to achieve the desired objectives.
Antagonistic Potential of Lophophora williamsii, Vinca minor and Hydrastis canadensis against Dental Caries Associated Bacteria

Introduction: Dental caries is a bacterial illness that causes localized disintegration and loss of calcified components in the teeth. Different plant extracts have been used to assess the anti-bacterial activity against the pathogens known to induced dental caries. Objective: The aim of this research is to determine the antibacterial potential of Lophophora williamsii, Vinca minor, and Hydrastis canadensis against dental caries associated bacteria. Methodology: The antibacterial activity of aqueous and methanol extracts of Lophophora williamsii (LW), Vinca minor (VM), and Hydrastis Canadensis (HC) was studied. Streptococcus mutans (S. mutans), Lactobacillus acidophilus (L. acidophilus), Pseudomonas aeruginosa (P. aeruginosa), and Staphylococcus aureus were the bacteria employed (S. aureus). The disk diffusion method was used to determine the tendency of bacterial strains towards the two extracts. Results: S. pyogenes and S. aureus were the most susceptible bacteria, whereas P. aeruginosa was the least susceptible. The methanol extracts of Vinca minor (VM) and Hydrastis Canadensis (HC) had the highest antibacterial activity against S. pyogenes and S. aureus, whereas the aqueous extract of Lophophora williamsii (LW) had the lowest antibacterial activity against (L. acidophilus) and (L. acidophilus) (P. aeruginosa). Methanolic extracts of almost all materials outperformed aqueous extracts in suppressing pathogenic bacteria growth but were less effective than ciprofloxacin extracts used as positive controls. All of the samples had saponins, according to phytochemical analysis. Vinca minor and Hydrastis Canadensis had alkaloids, while Lophophora williamsii contained flavonoids. Only Vinca minor and Hydrastis Canadensis contained tannins, respectively. Conclusion: Methanolic extracts of practically all materials suppressed pathogenic bacteria growth better than aqueous extracts, although not as well as ciprofloxacin extracts used as positive controls. Plant herbal blends have made major contributions to human health and well-being; as a result, plants have long been seen as a source of hope for novel therapeutic compounds.
Individual and Co-Expression Patterns of FAM83H and SCRIB at Diagnosis Are Associated with the Survival of Colorectal Carcinoma Patients

Background: FAM83H is important in teeth development; however, an increasing number of reports have indicated a role for it in human cancers. FAM83H is involved in cancer progression in association with various oncogenic molecules, including SCRIB. In the analysis of the public database, there was a significant association between FAM83H and SCRIB in colorectal carcinomas. However, studies evaluating the association of FAM83H and SCRIB in colorectal carcinoma have been limited. Methods: The clinicopathological significance of the immunohistochemical expression of FAM83H and SCRIB was evaluated in 222 colorectal carcinomas. Results: The expressions of FAM83H and SCRIB were significantly associated in colorectal carcinoma tissue. In univariate analysis, the nuclear expressions of FAM83H and SCRIB and the cytoplasmic expression of SCRIB were significantly associated with shorter survival of colorectal carcinomas. The nuclear expressions of FAM83H and SCRIB and the cytoplasmic expression of SCRIB were independent indicators of shorter cancer-specific survival in multivariate analysis. A co-expression pattern of nuclear FAM83H and cytoplasmic SCRIB predicted shorter cancer-specific survival (p < 0.001) and relapse-free survival (p = 0.032) in multivariate analysis. Conclusions: This study suggests that FAM83H and SCRIB might be used as prognostic markers of colorectal carcinomas and as potential therapeutic targets for colorectal carcinomas.
Mobile Instant Messaging Uses and Technostress: A Qualitative Approach

Abstract A growing number of people use mobile instant messaging (MIM) apps for a variety of purposes—most commonly related to social interaction, but also to coordinate work-related activities, fulfill informational needs, and discuss politics and public affairs. Despite its convenience for daily life, MIM may also act as an environmental antecedent of technostress due to users’ inability to cope with the demands of the app in a healthy manner. We conducted two qualitative studies (N1 = 26; N2 = 147) to examine why people use MIM apps in their daily life and if diverse uses relate to MIM stress differently. This research (1) develops a general catalogue of MIM uses; (2) suggests a four-dimensional construct of MIM technostress consisting of overload, ambiguity, invasion, and urgency; (3) outlines several differences across age groups and between genders; and (4) describes possible relationships between MIM uses and stress.
Handbook of functional connectivity Magnetic Resonance Imaging methods in CONN

This handbook describes methods for processing and analyzing functional connectivity Magnetic Resonance Imaging (fcMRI) data using the CONN toolbox. The first chapter (fMRI minimal preprocessing pipeline) describes standard and advanced preprocessing steps in fcMRI. These steps are aimed at correcting or minimizing the influence of well-known factors affecting the quality of functional and anatomical MRI data, including effects arising from subject motion within the scanner, temporal and spatial image distortions due to the sequential nature of the scanning acquisition protocol, and inhomogeneities in the scanner magnetic field, as well as anatomical differences among subjects.Even after these conventional preprocessing steps, the measured blood-oxygen-level-dependent (BOLD) signal often still contains a considerable amount of noise from a combination of physiological effects, outliers, and residual subject-motion factors. If unaccounted for, these factors would introduce very strong and noticeable biases in all functional connectivity measures. The second chapter (fMRI denoising pipeline) describes standard and advanced denoising procedures in CONN that are used to characterize and remove the effect of these residual non-neural noise sources.Functional connectivity Magnetic Resonance Imaging studies attempt to quantify the level of functional integration across different brain areas. The third chapter (functional connectivity measures) describes a representative set of functional connectivity measures available in CONN, each focusing on different indicators of functional integration, including seed-based connectivity measures, ROI-to-ROI measures, graph theoretical approaches, network-based measures, and dynamic connectivity measures.Second-level analyses allow researchers to make inferences about properties of groups or populations, by generalizing from the observations of only a subset of subjects in a study. The fourth chapter (General Linear Model) describes the mathematics behind the General Linear Model (GLM), the approach used in CONN for all second-level analyses of functional connectivity measures. The description includes GLM model definition, parameter estimation, and hypothesis testing framework, as well as several practical examples and general guidelines aimed at helping researchers use this method to answer their specific research questions. The last chapter (cluster-level inferences) details several approaches implemented in CONN that allow researchers to make meaningful inferences from their second-level analysis results while providing appropriate family-wise error control (FWEC), whether in the context of voxel-based measures, such as when studying properties of seed-based maps across multiple subjects, or in the context of ROI-to-ROI measures, such as when studying properties of ROI-to-ROI connectivity matrices across multiple subjects.
Systems-oriented talent management : a design and validation study

In 2012, Brouwer introduced the initial systems-oriented talent management (STM) model: a method to build a sustainable match between an organisation and its (future) employees by aligning business purpose and human talent from both a psychological and a managerial perspective. The STM model was elaborated into an online assessment instrument, named STM-scan. The initial STM-scan has been used over 1,000 times. Multiple intermediate evaluations affirmed that clients and candidates are satisfied with the application possibilities and the insights provided by the tool. However, the design of the STM-scan was based solely on practice. This raises a couple of questions. First, there is the question of whether the composition and configuration of the STM can also be scientifically proven. Second, it brings up the question of whether the initial version supports two of the key criteria of the COTAN review system: reliability and validity. Finally, it raises the question of what can be asserted about STM’s utility. Consequently, this dissertation is a design and validation study of the initial systems-oriented talent management model. In order to evaluate the best-practice oriented model and to design and validate an evidence-based version of the initial STM-scan, the current study used both qualitative and quantitative research methods. The improved STM contributes to the future bridging of the gap between psychological questionnaires for testing human characteristics and models for unravelling managerial building blocks. The design and validation studies in this dissertation confirmed that this conduces to a more sustainable and age-dependent match between the organisation’s rationale and a person’s innate individual character. Therewith, the study joined the debate on how an adaptive enterprise ought to be organised these days and how to give shape to the corresponding upscaling that is required of their talent management experts.
