Authors: Sayyed Asmaa 
Published: August 2024

The study objective is to evaluate the current ergonomic situation of the design of the work station in the libraries of Helwan University. This is to determine the positives and monitoring the negatives in the current work station and to identify the effect of the current design of the Helwan libraries. As to the effect of the health and physical state of the librarians and the users at the Helwan University libraries, and study the feasibility of applying the ergonomics standard in libraries at Helwan University. The study was based on the field survey methodology to obtain detailed and accurate information on the current situation of the design of the workstation in Helwan University libraries, (sample study), through the following data collection tools are: checklist, a questionnaire for librarians, and a questionnaire for users. The most important results of the study are the lack of compatibility of the design requirements in the workstation of most of the libraries under the ergonomics standard, and the dissatisfaction of the librarians and the users of the design of the workstation in most of the studied sample libraries. The study also showed that the library administrations did not organize any of the training courses on awareness of how to avoid occupational injuries, and there is no knowledge of the librarian on ergonomics and how to follow the principles of ergonomics in action to maintain occupational health and safety.
The study concluded with a number of recommendations the most important of which was the necessity of cooperation between the University Administration and the General Administration of Libraries to prepare the ergonomics program, for the development and redesign of the workstation at Helwan University libraries. The need of ergonomics is to raise the level of satisfaction of librarians and the satisfaction of users for the library services provided by the library, and make the library services more effectively. The allocation of breaks for employees to relax, and to have some exercises that help to maintain a health body and avoid occupational injuries. With the provision for a suitable area and the need to develop a specialized training courses for the libraries ergonomics programs is the correct way to perform the work without causing injuries.

This study aims to explore the Alignment of academic and professional preparation of the outcomes of the archive management discipline, Department of Information Studies at Sultan Qaboos University from the standpoint of employers and students regarding the needs of Omani labor market. The study adopted the mixed method approach in data collection in two principal stages: The first stage used the qualitative approach and employed the focus group for data collection from the group under study represented by students enrolled in the discipline and interviews conducted for data collection from sample group including records management staff or their deputies in matters of practical training in government institutions. The findings were analyzed using thematic analysis. The second stage is devoted to quantitative data collection as a complementary tool for the primary tool and for the purpose of in depth analysis or study in addition to enhancing the credibility of the findings by using revision forms. The forms include the paths of study in order to identify students’ views about such paths, their importance and in what way they benefited from them and the same applies to records management staff.

The findings recorded a 100% consensus among the sample group that the period and time of practical training are quite sufficient for archive management students despite the fact they prefer the training to be conducted during a single semester of study instead of two semesters – that is twice per week. This is in addition to the importance of practical training courses in developing their skills and translating their knowledge into practice. The study concluded that the academic preparation of archive management students offered by the department of information studies is quite considerate and responsive to the needs of the Omani labor market and that the skills gained by the students are satisfactory for their effective deployment in the labor market. The study came up with several recommendations including the update and development of a set of paths within the plan of archive management program that keep in pace with the rapid and accelerated developments in the labor market and establishing of partnerships between government institutions and university institutions in order to strike a balance between the professional and academic preparation of students archive management studies and the needs of the labor market.

Authors: Fatikha Dina , Nurmawati Thatit 
Published: August 2024

The most common complaint felt by patients due to fractures and the main complaint of patients after surgery is pain. Pain that is felt continuously can result in clinical and psychological changes. Benson's relaxation can be an alternative intervention in patients with Post Open Reduction Internal Fixation (ORIF) limb fractures to reduce pain by stimulating the pituitary gland to release endorphins and inhibit pain impulses from the cerebral cortex and thalamus. Benson Relaxation is safe and easy to do, has no risk of injury/side effects. The purpose of this study was to determine the effect of Benson relaxation on pain in patients with Post Open Reduction Internal Fixation (ORIF) limb fractures in the Dahlia Room at Mardi Waluyo General Hospital, Blitar. The research design uses a quasi-experimental pre-post test design. The population was all post ORIF patients with extremity fractures in the Dahlia (surgical) room at Mardi Waluyo Blitar Hospital with a total of 35 patients. The sample was post ORIF extremity fracture patients in the Dahlia Room of Mardi Waluyo General Hospital Blitar with a total sample of 13 respondents in each group using the Consecutive Sampling technique. Pain measurement data uses a Numerical Rating Scale. Statistical test using independent t-test. The results showed that the mean decrease in pain score in the Benson relaxation intervention group was 1.10, while the mean decrease in pain score in the control group was 0.44 with a pvalue of 0.00 <��� 0.05. It was concluded that there was an effect of Benson relaxation on pain in patients with Post Open Reduction Internal Fixation (ORIF) limb fractures. Benson relaxation is effective in reducing pain in patients with post open reduction internal fixation (ORIF) limb fractures. There needs to be a standard operating procedure regarding Benson's relaxation, so that later it can be implemented by all nurses.Keywords: Benson Relaxation, Pain, Fracture, Post ORIF

Maintaining Stabilization of Blood Sugar Levels in Diabetes Mellitus Patients with Foot Exercises: Case Report
Authors: Purwanti Lina Ema , Nur 'Aini Ani 
Published: August 2024

The chronic hyperglycemia of diabetes is associated with long-term damage, dysfunction, and failure of different organs. Physical activity is one of the factors that affect glycemic management. This case study aims to maintain the stability of blood sugar levels in DM patients by applying leg exercises. The design of this research is a case report with a nursing process approach carried out on Diabetes Mellitus patients with nursing problems of unstable blood sugar levels. Nursing care was carried out for seven days at the Muhammadiyah Ponorogo General Hospital. The intervention implemented is foot exercises. The results of the case study are presented in the form of nursing documentation. The case study results showed that the patient's blood sugar levels tended to be stable starting on the second day of the intervention.Exercise-induced glycemic control is mostly explained by an increase in whole-body insulin sensitivity. The long-term advantages of frequent exercise on glycemic control appear to be related to the cumulative effect of transitory gains in insulin sensitivity and glycemic control after each bout of exercise, rather than structural changes in insulin sensitivity.

Published: August 2024

Background
The acquisition of motor skills is a key element in many sports. A motor learning principle, which is frequently used to support skill acquisition is the application of different attentional foci. The effectiveness of different attentional foci on performance and the learning of motor skills has been investigated in various sports using randomised controlled trials. The aim of the present study was to investigate the effectiveness of different attentional foci (such as external (EFA) and internal attentional foci (IFA), but also holistic and switching foci) on the performance and learning of a sport-specific motor task in healthy individuals.

Methods
This study was a systematic review with network meta-analysis. We followed the Prisma reporting guideline and the Cochrane handbook for systematic reviews. Cinahl, Embase, Medline and Cochrane Central were searched for eligible studies. Network meta-analyses were performed for the post-acquisition, retention and transfer test endpoints.

Results
Twelve studies were included in the review. At post-acquisition an EFA was the most effective intervention compared to the control intervention (SMD: 0.9855; 95% CI [0.4–1.57]; p: 0.001). At the retention and transfer test endpoints, a holistic focus of attention had the highest effectiveness compared to an IFA (SMD 0.75; 95% CI [−0.1 to 1.6]; p: 0.09) and (SMD 1.16; 95% CI [0.47–1.86]; p: 0.001).

Discussion
For all three endpoints, we analysed a greater effectiveness of an EFA and holistic focus compared to an IFA. Several promising different attentional focus interventions were identified. The largest effects were analysed for a holistic focus. However, only one study used this intervention and therefore there remains uncertainty about the effectiveness. With regard to the inconsistency observed, the analysis at post-acquisition should be interpreted with caution. Modified versions of the EFA were the imagined and the dynamic EFA. Both were only explored in single studies and should therefore be investigated in further follow-up studies that directly compare them.
Tracking the Decision‐Making Process in Multiple‐Choice Assessment: Evidence from Eye Movements

Published: August 2014

SummaryThis study investigated students' decision‐making processes in a knowledge‐assessing multiple‐choice (MC) test using eye‐tracking methodology. More precisely, the gaze bias effect (more attention to more preferred options) and its relation to domain knowledge were the focus of the study. Eye movements of students with high (HPK) and low (LPK) prior domain knowledge were recorded while they solved 21 MC items. Afterwards, students rated every answer option according to their subjective preference. As expected, both HPK and LPK students showed a gaze bias towards subjectively preferred answer options, whereby HPK students spent more time on objectively correct answers. Furthermore, a fine‐grained time‐course analysis showed similar patterns of attention distribution over time for both HPK and LPK students, when focusing on subjective preference levels. Thus, these data offer a new perspective on knowledge‐related MC item solving and provide evidence for the generalizability of the gaze bias effect across decision tasks.

The sulfonation of poly(ether ether ketone) as investigated by two‐dimensional FTIR correlation spectroscopy
Authors: Al Lafi Abdul G. 
Published: August 2014

ABSTRACTFourier transform infrared and two‐dimensional correlation (2D‐COS) spectroscopies were used to follow the structural alteration occurring upon sulfonation of poly(ether ether ketone), in concentrated sulfuric acid at room temperature. With the help of high resolution and high sensitivity 2D‐COS, it was possible to locate the aromatic ring in which the substitution has taken place. Two new IR bands at 1288 and 1320 cm−1 were attributed to substitution occurring on the aromatic ring flanked with two ether groups. Limited oxidation effects of concentrated sulfuric acid manifested itself by the production of new carbonyl species absorbing in the IR at 1720 and 1750 cm−1 that were attributed to a fluorenone‐type structure and to ester groups. The 2D‐COS analysis showed that the band at 1470 cm−1 is not only due to the new substitution by sulfone groups and can not be used in the determination of sulfonation degree. Instead, the intensity of the 1490 cm−1 band, which can be attributed to skeletal ring vibration, was found to correlate well with the degree of sulfonation calculated from 1H NMR spectroscopy. The infrared spectroscopy combined with 2D‐COS provides a fast and powerful method for qualitative polymer structure verification and help to establish the quantitative analysis. © 2014 Wiley Periodicals, Inc.

Published: August 2014

ABSTRACTIn this article, the hydrodynamic behavior of dilute aqueous solutions of a natural polysaccharide—gellan in the porous media under the modeled oilfield conditions is described. The hydrodynamic properties of gellan and poly(acrylamide) solutions in saline porous media are compared. The influence of inorganic salts NaCl, KCl, CaCl2, MgCl2, and BaСl2 on sol–gel and gel–sol transitions of dilute gellan solutions was evaluated. The mechanism of sol–gel transition in the presence of individual alkaline and alkaline‐earth metal salts is described on the basis of literature data. The viscometric measurements revealed that the effectiveness of salts to enhance gelation of gellan changes in the following order: BaСl2 > CaCl2 ≈ MgCl2 > KCl > NaCl. The sol–gel and gel–sol phase transitions of gellan solution were also observed upon addition of oil field water containing 73 g L−1 of alkaline and alkaline earth metal ions. During the injection of gellan solutions into the porous media saturated by saline water an oscillation of the injection pressure was observed. Such behavior of gellan is explained by either the sol‐to‐gel and the gel‐to‐sol transitions of the polymer taking place in saline water or the step‐by‐step plugging of high permeable channels until all high permeable channels of sand packs are plugged due to gellan invasion. The application of brine‐initiated gelation of gellan for water shutoff operations (WSO) in field conditions was demonstrated. Higher technological effectiveness of gellan injection in comparison with existing gelation systems was shown. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41256.
The index of dry‐jet wet spinning for polyacrylonitrile precursor fibers

Published: August 2014

ABSTRACTA new spinning index for a PAN precursor fiber is proposed that includes the viscosity of a spinning dope, the thermodynamic affinity, and the draw ratio during the spinning process. Through dry‐jet wet spinning, six types of PAN precursor fibers with different spinning parameters, including solid content, solvent content in a bath, and draw ratio, were fabricated and analyzed with tensile tests, SEM, and XRD. The results show that the spinning index can reflect the mechanical properties of the fibers but is less indicative of crystallinity. Hence, the current spinning index is recommended for use as an indicator for the mechanical properties of PAN precursor fibers. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41265.
Accelerating the graphitization process of polyimide by addition of graphene

Published: August 2014

ABSTRACTIn this article, a composite film from polyimide and thermally exfoliated graphene was prepared through in situ polymerization, and the weight percent of thermally exfoliated graphene with respect to the polyimide monomers was 5 wt %. The film was carbonized at 1000°C for 1 h and then heat‐treated at various temperatures up to 2100°C. For comparison, the corresponding pure polyimide film was also prepared and heat‐treated at the same condition. It was found that the addition of graphene could effectively prevent the polyimide film from shrinking in the direction parallel to the film surface during the heat treatment. Furthermore, the results of density, X‐ray diffraction, shrinkage in the direction perpendicular to the film surface and scanning electron microscopy revealed that the graphitization process of the polyimide could be accelerated by addition of graphene obviously. In view of the above phenomena, a reasonable explanation was presented. © 2014 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41274.

Published: August 2014

ABSTRACTSuccinic acid was presented as a small molecule low shrinkage additive (LSA) in unsaturated polyester resin (UPR). The effects of succinic acid on the volume shrinkage and the flexural strength of UPR cured at 80 ± 1°C were investigated and compared with those of macromolecule LSAs, including polyvinyl acetate (PVAc), polymethyl methacrylate (PMMA), and polystyrene (PS). The results indicated that the volume shrinkage of succinic acid/UPR specimen was significantly lower than those of specimens with macromolecule LSAs. The flexural strength of succinic acid/UPR specimen was improved. The optimal time of pre‐esterification between succinic acid and the excess dihydric alcohol in UPR was 3.0 h, and the optimal addition of succinic acid was 20 g per 100 g UPR. Compared with 2,2‐dimethyl malonic acid we put forward before, succinic acid was a cheaper and more commercial LSA, which obviously accelerated the pre‐esterification process and presented excellent antishrinkage effect. DSC showed that with the addition of succinic acid, the polymerization of UPR was distinctive. The two‐stage polymerization of UPR glue including the cross‐polymerization of UPR and the homopolymerization of polyester was changed to a one‐stage polymerization with lower exotherm and slower polymerization rate, which was optimal for UPR. FTIR and high resolution magic angle spinning nuclear magnetic resonance (HR/MAS NMR) were applied for the quantitative characterization of pre‐esterification caused by succinic acid. Succinic acid performed better effects on the polymerization of UPR as compared to previous LSAs, and finally the homogeneous micro‐structure of cured succinic acid/UPR formed and was demonstrated by SEM. © 2014 Wiley Periodicals, Inc.

Published: August 2014

AbstractThe construction of efficient synthetic functional receptors with tunable cavities, and the self‐organization of guest molecules within these cavities through noncovalent interactions can be challenging. Here we have prepared a double‐cavity molecular cup based on hexaethynylbenzene that possesses a highly π‐conjugated interior for the binding of electron‐rich guests. X‐ray crystallography, NMR spectroscopy, UV/Vis spectroscopy, fluorescent spectroscopy, cyclic voltammetry, and SEM were used to investigate the structures and the binding behaviors. The results indicated that the binding of a guest in one cavity would affect the binding of the same or another guest in the other cavity. The effect of electron transfer in this system suggests ample opportunities for tuning the optical and electronic properties of the molecular cup and the encapsulated guest. The encapsulation of different guests would also lead to different aggregate nanostructures, which is a new way to tune their supramolecular architectures.

Published: August 2014

AbstractA direct large volume injection high‐performance liquid chromatography (HPLC) method with homemade restricted‐access media (RAM) pre‐column and combined with a column‐switching valve was established and developed for determination rifampicin (RIP) in rat plasma. The rat plasma samples (100 μL) were injected directly onto pre‐column, where RIP was retained and pre‐concentrated, while proteins were washed to waste using a methanol–water (5:95) as the mobile phase at a flow rate of 1 mL/min. Then, by rotation of the switching valve at 5 min, the RIP were eluted from the pre‐column and transferred to an Luna C18 analytical column by the chromatographic mobile phase consisting of methanol–acetonitrile–10 mm ammonium format (60:5:35) at a flow rate of 1 mL/min. The total analytical run time was 15 min with UV detection wavelength at 254 nm. Carbamazepine was used as the internal standard. Excellent linear correlation (r = 0.9993) was obtained in the range of 0.25–8 µg/mL for rat plasma. The intra‐day and inter‐day precisions of RIP were all <5.0%. The recoveries were in the range of from 99.98–113.66% for plasma. This on‐line RAM‐HPLC method was successfully applied to the pharmacokinetic study of RIP in rat plasma.
