This study was aimed to develop three-dimensional (3D) porous scaffold from blending of chitosan/fish scales collagen/glycerin/nano zinc oxide for skin tissue engineering and skin regenerating template. 3D porous scaffolds were fabricated through freeze dry technique. The 3D porous scaffolds were subjected to phosphate buffer solution (PBS) washing while dehydrothermal (DHT) treatment and chemical treatment using 1-ethyl- 3-(3-dimethylaminopropyl)carbodiimide (EDAC)-N-hydroxysuccinimide (NHS) were used to create crosslinks. The mechanical properties, porosity and swelling ratio of the 3D porous scaffolds have been determined using general procedures. Crosslink density was calculated using the Fourier Transform Infrared (FTIR) technique while the crosslinking degree has been determined using 2,4,6-trinitrobenzenasulfonic acid (TNBS). Field emission scanning electron microscopy (FESEM) analysis was used to examine the morphology of 3D porous scaffolds. The biodegradation rate and cytocom.....

The purpose of the study was to evaluate the implementation of the Free Education Program (FEP) in Palembang, Indonesia that has been implemented since 2009. The population of the study was all the 22 public senior high schools in Palembang. The sample consisted of 14 school heads, 33 members of school management teams, and 150 teachers in the 14 schools. School heads and school management teams were chosen through purposive sampling, while teachers were chosen via stratified random selection. The research design used a combination of qualitative and quantitative approaches involving questionnaire, interview protocol, and document analysis. The findings show that FEP is actually a funding policy from the province and the city government in addition to the existing School Operational Funding Assistance (BOS) and a one-off fund granted upon application from the central government. Respondents perceived that the overall fund was insufficient to run the school activities. Several issues re.....

The aim of this research is to contribute further results on the coverings of some finite groups. Only non-cyclic groups are considered in the study of group coverings. Since no group can be covered by only two of its proper subgroups, a covering should consist of at least 3 of its proper subgroups. If a covering contains n (proper) sub- groups, then the set of these subgroups is called an n-covering. The covering of a group G is called minimal if it consists of the least number of proper subgroups among all coverings for the group; i.e. if the minimal covering consists of m proper subgroups then the notation used is σ (G) = m. A covering of a group is called irredundant if no proper subset of the covering also covers the group. Obviously, every minimal cover- ing is irredundant but the converse is not true in general. If the members of the covering are all maximal normal subgroups of a group G, then the covering is called a maximal covering. Let D be the intersection of all members i.....

Tujuan kajian ini adalah untuk mengenal pasti pemahaman pensyarah terhadap Pembelajaran Berasaskan Projek (PBP) dan aplikasinya dalam pengajian seni digital di institusi pengajian tinggi (IPT). Persepsi pelajar-pelajar yang terlibat diambil kira untuk melihat kesan PBP kepada para pelajar. Kajian ini menggunakan reka bentuk kajian kes kualitatif. Kaedah yang digunakan untuk mengumpul maklumat adalah temu bual, pemerhatian dan analisis dokumen. Kebolehpercayaan data dilakukan melalui triangulasi dan penilaian tiga orang pakar. Informan kajian adalah terdiri daripada lima orang pensyarah daripada lima buah IPT di semenanjung Malaysia yang menjadi tenaga pengajar dalam bidang seni grafik, multimedia dan animasi serta sepuluh orang pelajar daripada IPT yang sama. Dapatan kajian menunjukkan pemahaman pensyarah terhadap PBP merujuk kepada tugasan berorientasikan produk, asas kemahiran, pembelajaran bersepadu, dan pembelajaran autentik. Manakala aplikasi PBP dilihat daripada aspek rancangan t.....

This study was aimed to investigate the impact of pre service teachers' (PSTs') Mathematical Knowledge for Teaching (MKT) on the Mathematical Quality of their Instruction (MQI). A case study involving three pre service teachers (PSTs) was carried out to detail the MQI and the domains of MKT they hold. The context of the study was the final practicum placement for three participants in the fourth year of their degree program (Bachelor of Teaching- Primary Mathematics). The study employed observational approach using video-recording of classroom teaching and interviews as its primary method. Observational notes, participants' lesson plans and reflective writing were used to compliment the video data. Two protocols, the Pre service Teachers' MKT protocol (PTMKT) and Pre service Teachers' MQI protocol (PTMQI) were developed to code and analyze the data. The MQI were coded and analyzed using the PTMQI protocol. Similarly, participants' MKT was determined through the analysis of interview tr.....

This study aims to develop and validate the Teacher Leadership Knowledge Model in order to determine the key factors of teacher leadership knowledge among Malaysian teachers. This study applied a quantitative approach using survey research strategy and questionnaires as the research instrument. A total of 413 trained teachers from schools in Petaling Perdana district, Selangor were selected using proportional stratification sampling and simple random sampling. Data in this study were analysed using Exploratory Factor Analysis (EFA) and Confirmatory Factor Analysis (CFA) to test the validity of the Teacher Leadership Knowledge Model. The EFA yielded a three-factor sub constructs namely Collaborative Culture In and Beyond School, Improvement in Instructions and Student Learning and Organizational Development with the acceptable Cronbach Alpha values that were .926, .817 and .827 respectively. The study also found that, in the First Order CFA the goodness-of-fit indexes indicated that the.....
