E-Teaching in Teacher Education—A Conceptual Framework of Sultan Idris Education University

Teacher education programs are essentially institution-based.Their students need to be exposed more to the realities of school and community.Internship,practice of teaching,practical activities,and supplementary educational activities are better planned and organized more systematically.Malaysian government announced that in 2020 all the primary and secondary school teachers must be graduated.In accordance to that,Sultan Idris Education University is offering the distance learning education to all school teachers.The frame work of the teaching involves e-learning.E-education involves e-teaching and e-learning along with the various administrative and strategic measures needed to support teaching and learning in an internet environment.It will incorporate a local,regional,and national view of education.This paper will be analyzing the e-teaching which involves distance learning in Sultan Idris Education University.

A Brief Review on Biomedical Applications of Hydroxyapatite Use as Fillers in Polymer

Preparation of hydroxyapatite(HA)through natural sources,such as fish scales or synthetic HA produced from the chemical reaction has been widely used as biomedical materials because HA is bioactive,non-toxic and osteoconductive with a crystallographic structure almost similar to that of the bone mineral.In addition,HAwith particle size<10 microns is classified as common inorganic filler used to improve the mechanical properties and biocompatibility of polymer composites.The purpose of this review is to collect information related to HA,and to provide readers with information about synthesis methods,advantages of hydroxyapatite as biomaterial,biomedical applications of polymer/HA composites.

Preparation of Fish Scales Hydroxyapatite (FsHAp) for Potential Use as Fillers in Polymer

The aims of this study were to prepare natural hydroxyapatite from fish scales(FsHAp)for potential use as a filler in polymer.The FsHAp was prepared from Tilapia fish scales using thermal method.The FsHAp was milled for 48 h and dried by spray method.The morphology was characterized using field emission scanning electron microscope(FESEM)which showed irregular shape of FsHAp particles with particle size around 7μm.The analysis of FsHAp was carried out using Fourier transform infrared spectroscopy(FTIR)and X-ray diffraction(XRD)to confirm chemical structure of FsHAp.

Effect of Frozen Storage on the Quality of Frozen Foods—A Review

This paper reviews the quality changes that occur towards the food products during the frozen storage period.This research aims to determine the significant physical and chemical changes that had occurred onto the frozen foods.Indeed,refrigerated storage is the easiest way to preserve food within short handling time.Based on the observation,it was discovered that the kinetics reactions help to establish computer-aided quality,prediction models.In certain food products,the negative impact of temperature indicated the need for a thorough evaluation of the quality parameters of individual’s kinetics reaction.In general,a reasonable temperature to store food is-18°C for most frozen foods,and this will retain the quality of commercial storage.

Effect of lyophilized aqueous leaf extract of Aquilaria subintegra on aphrodisiacproperties in mice

Objective: To investigate the effects of Aquilaria subintegra leaf aqueous extracts on the aphrodisiac properties including sexual behaviour, testosterone level, percentage of pregnancy, number of offspring and male to female ratio of offspring in ICR mice. Methods: In this experiment, each male cohabitated with one female in a polysulfone cage. 30 ICR male mice were divided into 6 groups that received normal saline (the control group), 50 mg/kg, 100 mg/kg, 200 mg/kg, 500 mg/kg, and 1000 mg/kg body weight of Aquilaria subintegra leaf aqueous extracts orally for 21 days consecutively. Sexual behavior, percentage of pregnancy, number of offspring and male to female ratio of offspring in ICR mice were measured according to the established methods. Testosterone level was measured by using enzyme-linked immunosorbent assay. Results: Mice that received Aquilaria subintegra leaf aqueous extracts at 50 mg/kg body weight (day 0) had significantly higher mount frequency as compared to the control group;groups treated with 100, 500, 1000 mg/kg body weight extracts produced a greater number of offsprings when compared to the control group. All aphrodisiac parameters were similar between the treatment groups and the control group, indicating that Aquilaria subintegra leaf aqueous extract did not significantly alter the aphrodisiac parameters. Conclusions: Aquilaria subintegra leaf aqueous extracts have no effect on the aphrodisiac properties, but could increase the breeding rate in mice.

Characteristics and Influence of Multimedia Technology on Dance Choreography

In contemporary times,with the development of multimedia technology,especially in consideration of the advantages of multimedia technology in performance,dance,as an expressive art,is bound to be concatenated with multimedia technology to enrich its form of display.The influence of multimedia technology in dance choreography on dance works and the effect of multimedia technology itself on dance choreography are worth further discussion.There is no doubt that with the application of multimedia technology in the dance field,choreographers have more open and creative ideas.Perhaps,in view of the role of multimedia technology in dance creation,the involvement of various disciplines and different technologies in dance choreography would expand in the future.However,it is necessary to consider the integration of new technologies,especially the negative impact of their improper use on the expression of dance works.Therefore,this study aims to explore the elements and relations between multimedia technology and dance choreography in the new era,seek for methods and rules of multimedia technology in dance creation,pursue its positive significance,and provide certain theoretical reference for the creation of dance works through multimedia technology.

Langmuir-Schaefer Film Investigation and Density Functional Theory Band Gap Calculations of Calix[n]arene-Para-Aminobenzoic Acid for Drug Nanosensor Application

Calix[n]arenes was utilized to detect PABA,the primary sunscreen component.This study investigates the interaction of calix[4]arene(C4),calix[6]arene(C6),and PABA using the Langmuir method and first-principle density functional theory(DFT).Using the Langmuir-Schaefer(LS)technique,an ultrathin film composed of calix[n]arenes and their complexes with PABA was deposited on various substrates.Based on the Langmuir study,the PABA molecule was bonded to the lower rims of both C4 and C6 with the host-guest ratio of 1:1.All of the LS films formed were then characterized by ultravioletvisible spectroscopy(UV-Vis),Fourier-transform infrared spectroscopy(FTIR)and carbon,hydrogen,nitrogen,sulfur elemental analyzer(CHNS).The band gap reduction obtained in the DFT study denotes the charge transfer interaction with promising reactivity between the calix[n]arenes and PABA.The sensing of PABA by C4 and C6 is successful based on the formation of bonding between them due to the hosts’effective trapping capacity.The outcomes of this study could be applied to drug delivery systems for future pharmaceutical and medical applications.
