The Efficiency of Well-Written Manuals Aided-Hand Knotting Skills Acquisition for Undergraduates

Introduction. Standard procedural skills training methods include a tutorial, workshop, and feedback. Written manuals might add value to those standard methods; nevertheless, it depends on how well they are composed. This research aimed to evaluate the efficiency of well-written manuals of hand-knotting skills to improve students' procedural skills learning and competency. Method. This research was conducted through a preliminary study to identify the assessor reliability and main study to evaluate the students' scores for reef and surgeon's knots using an objective structured assessment of technical skills (OSATS). Subjects' preparedness and perception of the quality of the manuals were evaluated through a survey. Students were randomly divided into two groups. The treatment group received written manuals a day before the workshop. Both groups experienced the same five steps procedural skills teaching methods. The results were analyzed by SPSS 17.0 through the Pearson Chi-square test and independent t-test. Results. A preliminary study showed that the assessors had no difference in evaluating students' skills. The main study included 31 subjects in the treatment group and 34 subjects in the control group. The OSATS scores were statistically significantly different between the groups. Students in the treatment group had higher mean scores (43.42±7.98) than those in the control group (27.21±5.64); p<0.05. None of the control group students felt prepared, and most students (77%) considered the manuals to be well written. Conclusion: Well-written manuals of hand-knotting skills given before skills training improve students' skills acquisition and the standard teaching methods.
Is Nonstandard Employment Hazardous to Workers' Health Status? A Focus on Special Employment in South Korea

Purpose: Workers in special employment relationship (WSERs) are workers in nonstandard employment arrangements who lack worker protection accorded in standard employment arrangements. This study aimed to describe self-rated health (SRH) and depressive symptoms (DS) among Korean WSERs in comparison to regular wage workers (RWW) and identify associations between working conditions and those outcomes. Methods: In this study, secondary data analysis using the 5th Korean Working Conditions Survey was used. The sample totaled 29,120, including 1,538 WSERs and 27,564 RWWs. Sociodemographic and work-related characteristics were employed as explanatory variables and SRH and DS as dependent variables. Using multiple logistic regression, the determinants of fair/poor SRH and DS were identified. Results: The prevalence rates for fair/poor SRH and DS in WSERs were 25.2% and 28.3%, respectively, and 20.7% and 25.0% in RWWs, respectively. Compared to RWWs, WSERs had 31% (aOR=1.31, 95% CI=1.14~1.49) and 20% (aOR=1.20, 95% CI=1.06~1.36) higher odds of SRH and DS, respectively. Some factors, such as a lack of rest guarantee and sickness presenteeism, had a larger influence in the WSER than in the RWW group. Conclusion: Compared to RWWs, WSERs reported having poorer working conditions and were more likely to report poor general and mental health. Therefore, in Korea, public health policymakers should consider measures to protect the working conditions and health of WSERs, a growing segment of the working population. The study produced new epidemiological evidence regarding the relationships between employment arrangements and health.

Prediction and Effect of Maternal Marginal Zinc Deficiency on Development, Redox Status, and Gene Expression Related to Oxidation and Apoptosis of Embryos

BackgroundMaternal severe zinc (Zn) deficiency induced oxidative damage and apoptosis in embryos, resulting in growth retardation. Therefore, it is crucial to assess maternal marginal Zn nutritional status for poultry breeders to prevent embryos subjected to severe Zn deficiency. MethodsIn Exp. 1, twelve egg embryos were sampled at incubation day 17 (E17), E20, E23, E26, E29, and E32 (day of hatch) respectively, with 6 replicates of 2 embryo each. The developmental changes of Zn mobilization and Zn transport gene mRNA expression were determined. In Exp. 2, 324 laying duck breeders were randomly allotted into 3 dietary Zn levels (0, 60, and 120 mg Zn/kg diet) with 6 replicates of 18 ducks per replicate. Plasma Zn concentration and erythrocytic Zn metalloenzyme activities in breeders as well as the development, redox status, and gene expression related to oxidation and apoptosis in embryos were measured. Blood samples were collected at the 2th, 4th and 6th weeks of the experiment. ResultsIn Exp. 1, the overall Zn mobilization rates were increased in yolk sac and embryonic liver in response to the increased incubation period, associated with the decreased ZIP10, 13, and 14 mRNA expressions in embryonic liver (P < 0.05). In Exp. 2, with the prolonged dietary Zn depletion, maternal Zn deficiency decreased plasma Zn concentration and erythrocytic alkaline phosphatase activity at the 6th week and inhibited erythrocytic 5'-nucleotidase (5’-NT) activity at 2th week (P < 0.05). On E29 of the maximal rate of Zn mobilization, maternal marginal Zn deficiency increased middle and late embryonic mortality and contents of superoxide anion radical, MDA and PPC, as well as decreasedMT content, CuZnSOD activity, and MT1 mRNA expression in embryonic livers (P < 0.05). Additionally, maternal marginal Zn deficiency increased BCL2-associated X protein and Caspase-9 mRNA expression and decreased B-cell lymphoma-2 mRNA expression in embryonic liver (P < 0.05). ConclusionErythrocytic 5’-NT activity was more rapid and reliable to assess marginal Zn-deficient status in duck breeders. Marginal Zn deficiency impaired hatchability and antioxidant defense system and then induced the oxidative damage and apoptosis in embryonic liver, contributing to the greater loss of embryonic death.

Several tools and platforms are being continuously introduced that support data science models while managing large data sets used to train data science models. Such a scenario lead to the emergence of DataOps. This paper summarises some of the good practices in the DataOps from the literature, offering guidelines intended to approach an organizational shift towards better data-driven decision making. This study presents a picture of the definition, the steps for adopting and challenges of the adoption of DataOps.
Improving Filtrate Quality Using Agrobased Materials as Coagulant Aid

In the present study, an evaluation of agrobased materials (ABM) as a coagulant aid in conjunction with alum has been conducted to determine their efficacy in water treatment. The agrobased materials evaluated are Surjana seed (Moringa oleifera), Nirmali seed (Strychnos potatorum) and maize (Zeemays). Experiments have been conducted simulating a conventional water treatment train consisting of coagulation-flocculation-settling and granular media filtration. Emphasis has been given to the filtration aspect of the treatment train using synthetic turbid water. The filter performance was defined by water quality and head loss development across the filter bed. When Nirmali seed or maize was used as a coagulant aid, the alum dose required was 25 and 15 mg/L, respectively, and the filtrate turbidity achieved was less than 0.2 NTU, whereas alum alone with a dose of 45 mg/L achieved filtrate turbidity levels higher than 1 NTU. Thus, the use of ABM improved the filtrate quality. Head loss in filter with Surjana seed and Maize as coagulant aids was comparable to that of alum alone, whereas it was higher when Nirmali seed was used as a coagulant aid.
When Practice Fails to Reduce Racial Bias on the Decision to Shoot: The Case of Cognitive Load.

Practice improves performance on a first-person shooter task (FPST), increasing accuracy and decreasing racial bias. But rather than simply promoting cognitively efficient processing, we argue that the benefits of practice on a difficult, cognitively demanding task like the FPST rely, at least in part, on resource-intensive, cognitively effortful processing. If practice-based improvements require cognitive resources, then cognitive load should compromise the value of practice by depriving trained participants of the cognitive resources on which they depend. This experiment shows that inducing cognitive load eliminates the benefits of training, leading to an increase in racial bias, as predicted.
Optimism and Perceived Social Support as Predictors of Posttraumatic Growth Among Emerging Adults After the Death of a Parent

For an individual in emerging adulthood (the transitional stage between adolescence and adulthood), the experience of a parent’s death can be a traumatic event that challenges the individual’s way of understanding the world. However, the experience can also bring positive changes as a result of the individual’s struggle with the crisis of parental death. That change, called posttraumatic growth, can be influenced by personal factors, such as optimism, and environmental factors, such as perceived social support. This study aimed to examine whether optimism and perceived social support predicted posttraumatic growth. The study design was a quantitative and cross-sectional study using the Posttraumatic Growth Inventory (PTGI), revised Life Orientation Test (LOT-R), and Multidimensional Scale of Perceived Social Support (MSPSS) as measurements. Participants were 66 emerging adults aged 18–25 years who experienced a parent’s death in the past 6 months to 3 years before the study. Results of regression analysis showed that optimism did not predict posttraumatic growth, whereas high perceived social support predicted high posttraumatic growth. Moreover, perceived social support from the family was the only source that positively predicted posttraumatic growth. This study suggests that social support is important to promote posttraumatic growth. Based on these results, mental health professionals can arrange intervention to increase social support to foster a better mental health condition for emerging adults who recently lost a parent.
Association between Bone Marrow Mesenchymal Stem Cell Characterization and Taking Inotropic Drugs in Patients with Severe Left Ventricular Dysfunction After Off-pump Bypass Surgery

Background and Aim: Left ventricular dysfunction is a frequent complication after coronary artery bypass graft (CABG) and is often treated with inotropic drugs to achieve suitable hemodynamic status. Bone marrow-derived mesenchymal stem cells (BMSCs) have potential effects on cardiac function. In this study, we aimed to identify the predictor role of MSCs in taking inotropic drugs in patients with severe left ventricular dysfunction undergoing CABG. Methods: The study included 30 patients who underwent off-pump CABG at Afshar Hospital and Seyed Al-Shohada Hospital. For investigating the possible association of BMSCs proliferation rate with taking inotropic drugs, the bone marrow samples aspired from patients' sternum during surgery. MSCs were isolated and counted after 4, 7, and 14 days using trypan-blue color, and then doubling times were calculated. Results: After cardiac surgery, the number of female patients who take inotropic drugs was significantly higher than men. Our data showed that the BMSCs doubling time in female patients who received inotropic drugs was less than that of male patients who received inotropic drugs (p < 0.05). Conclusion: Based on this investigation, we concluded that there was a clear relevance between the MSCs' doubling time and the inotropic drug requirements in patients who received inotropic drugs. *Corresponding Author: Zakieh Sadat Sheikhalishahi; Email: z.sheikhalishahi@gmail.com Please cite this article as Esmailidehaj M, Mirhosseini S.J, Sheikhalishahi Z.S.

How is Students' Understanding in Resolving Questions Related to Derivative Concepts?

Understanding is a cognitive ability that students must have. There are various ways to solve a question, it depends on the understanding that students have. When completing questions related to derivative concepts and graphically represented, students can solve them in different ways. This research aims to describe the characteristics of students who solve problems with conceptual and procedural understanding. This research is a qualitative study. The subjects of the study were two students who had different ways of resolving the problem. The supporting instrument used to dig up data is a task sheet whose contents are derivative questions. The results showed that the characteristics of students who solve problem with conceptual understanding are able to identify all information or concepts that can be used to solve the question, understand the definition of each concept that has been identified, able to associate all the information that has been identified in order to solve the question, and able to explain why the procedure used is correct to solve the problem. The student characteristics that solve the problem with procedural understanding are identifying some information contained in the problem, focusing only on the information used to construct the symbolic form, do not understand the information that has been identified, and relate concepts to one another, but it is meaningless. After reading this article, it is expected that teachers can choose the right learning method in teaching. Thus, both conceptual understanding and procedural understanding can be mastered by students.

Relieving efforts in palm‐tree tissue sampling for population genetics analyses

Abstract The young leaves are the main source of nucleic acids for population genetic studies in palm‐trees; however, the access to this tissue may be limited by specific features of each species. Using root tissues as an alternative source of nucleic acids could facilitate the sampling in large populations. This study tests root tissue viability as an alternative nucleic acid source (root versus. leaf) and explores different protocols (tissue storage and DNA extraction methods) to obtain high‐quality DNA samples. The results showed no significant differences in DNA concentration (603.7 vs. 599.1 ng/μl) and quality ratios (A260/280:2.1 vs. 1.9, and A260/230:2.1 vs. 2.0) for the comparisons of tissue source (leaf vs. root) and DNA extraction method (manual vs. kit). For tissue storage method, DNA concentration was significantly higher for root tissues stored in 70% and 90% alcohol solutions (692.8 and 822.6 ng/μl, respectively) versus those obtained from leaf tissue (603.7 ng/μl); however, for the quality parameters, no differences were found. Results showed the effective potential of using root tissue as an alternative source for nucleic acids, which could facilitate population sampling of palm‐tree species for future studies, and this methodological alternative could be applied to other plant systems with similar sampling challenges.
Influence of Nano Formulation on Augmenting the Seed Quality in Groundnut (Arachis hypogaea L.)

Background: Groundnut were mainly cultivated under rain fed condition, lack of initial seedling quality due to lower moisture conditions, it causes reduced crop yield and in sometimes it leads to crop failure. In order to overcome this problems, effective seed enhancement techniques as seed coating plays major role in maintaining the seed quality. Methods: The controlled release of bioactive molecules namely hormones gibberellic acid (GA3) as a smart delivery system can be achieved through seed coating in groundnut by exploiting advanced nanotechnology. Infusion of active ingredients as hormones (GA3) through the seed coating formulation by nano formulation methods. At nano level it influences the effects at higher level and gives best results through controlled release of hormones without any loss. Result: Due to nano formulation coating in groundnut, seeds had an effective results in all the parameters viz., imbibition rate (48%), speed of germination (5.5), germination percentage (87%), seedling length (24.7 cm), vigour index (2142), hydrolysing enzymes (α-amylase14.83 and lipase 1.481), which significantly differs from untreated seeds. Hence, it was concluded that the GA3 infused nano formulation coating at 15 ml per kilogram of seed can be used for seed quality improvement in groundnut for better seedling establishment.
Safety assessment of local cooperative warnings and speed limit information

The study was designed to assess the impacts of cooperative intelligent transport systems (C-ITS) on traffic safety. The aim was also to review assumptions made in some previous studies and verify or update the earlier safety estimates. Seven informative C-ITS services warning about various situations and hazards were selected in the study. The expert estimates provided were grounded on new evidence about driver behaviour, the crash categories created in the European Risk Calculation tool (ERiC), and literature. The C-ITS services were assessed to reduce the number of fatalities and injury crashes. The clearly biggest drop in fatalities was assessed for ‘In-vehicle signage, speed limit’, ‘Weather warning’ being the second most effective. The next effective were assessed to be ‘Warning of emergency braking ahead’ and ‘Road works warning’. The smallest but still positive impacts were assessed for ‘Traffic jam ahead warning’, ‘Car breakdown warning’ and ‘In-vehicle signage, child and pedestrian crossing ahead’. Generally, the effectiveness was assessed to be somewhat smaller for injury crashes than fatalities. The authors conclude that the results are positive both for implementing C-ITS services as such and as supporting measure for the deployment of more intervening ITS and automated driving.
