Pola Penontonan Televisyen Pendidikan Dalam Kalangan Ibu Bapa Kawasan Felda, Daerah Kota Tinggi , Johor

TV Pendidikan disediakan sebagai salah satu saluran menambah keberkesanan dalam proses pengajaran dan pembelajaran. TV Pendidikan turut membantu ibu bapa dalam usaha mendidikanak dengan program – program yang disediakan. Maka, kajian ini dijalankan untuk meninjausejauhmana tahap penontonan TV Pendidikan dalam kalangan ibu bapa, sejauhmana kesedaran ibubapa terhadap kewujudan TV Pendidikan dan EDUWEBTV serta masalah menonton TV Pendidikanyang dihadapi oleh ibu bapa. Instrumen kajian ini adalah berbentuk soal selidik yang diedarkankepada seramai 169 orang responden. Manakala persampelan adalah berbentuk kaedah persampelan rawak berkelompok dimana responden kajian terdiri daripada ibu bapa yang mempunyai anak yang masih bersekolah. Data-data dianalisis dengan menggunakan perisian Statistical Package For Social Sciences (SPSS) versi 10 dengan tahap kebolehpercayaan 0.8492. Analisis data dilakukan dengan menggunakan kaedah deskriptif iaitu berbentuk skor min, frekuensi dan peratusan. Hasil kajianmenunjukkan kekerapan penontonan TV Pendidikan adalah di tahap yang rendah manakala persepsiresponden terhadap TV Pendidikan dan kesedaran terhadap kewujudan EDUWEBTV di tahapsederhana. Dari segi masalah penontonan TV Pendidikan, masalah kurang kemudahan mencatatkanmin masalah penontonan tertinggi berbanding masalah masa siaran dan isi rancangan. Namun begitu,terdapat perbezaan signifikan diantara tahap pendidikan responden dengan kesedaran responden terhadap kewujudan EDUWEBTV

Study of zinc oxide thin film characteristics

This paper presents the characterization of ZnO thin films with the thickness of 8nm, 30nm, and 200nm. The thin films were prepared using sol-gel method and has been deposited onto different substrate of silicon wafer, glass and quartz. The thin films were annealed at 400, 500 and 600°C. By using UV-Vis, the optical transmittance measurement were recorded by using a single beam spectrophotometer in the wavelength 250nm to 800nm. However, the transmittance in the visible range is hardly influenced by the film thickness, substrate used and annealed temperature and the averages are all above 80%. On surface morphology observed by AFM and FESEM, the results show that the increase of film thickness and annealed temperature will increase the mean grain size, surface-to-volume ration and RMS roughness. Besides that, higher annealing temperature cause the crystalline quality to gradually improve and the wurtzite structure of ZnO can be seen more clearly. Nonetheless, the substrate used had no effect on surface morphology, yet the uniformity of deposition on silicon wafer is better than glass and quartz

Evaluation of the histological variability of core and wedge biopsies in nonalcoholic fatty liver disease in bariatric surgical patients

Background: Liver biopsy remains the gold standard for characterizing and evaluating treatment response in nonalcoholic fatty liver disease (NAFLD). Liver heterogeneity and sampling variability can affect the reliability of results. This study aimed to compare histological variability of intraoperative wedge and core liver biopsies from different lobes in bariatric patients, to better inform surgeons on biopsy method and guide interpretation of results. Methods: We prospectively recruited bariatric surgical patients. Intraoperative core biopsies were taken from the left and right lobe, with a wedge biopsy taken from the left. All biopsies were graded by a specialist liver pathologist, blinded to clinical details and biopsy site. Concordance of histological findings between sites was evaluated. Results: There were 91 participants (72.2% female), mean age 46.8 ± 12.0\ua0years, body mass index 45.9 ± 9.4\ua0kg/m. There was no significant pattern for up- or down-grading disease dependent on biopsy technique. Moderate to strong agreement was seen in the presence of NAFLD and nonalcoholic steatohepatitis (NASH, κ = 0.609–0.865, p < 0.001) between biopsy sites. Individual components (steatosis, inflammation, ballooning) showed weaker agreement (κ = 0.386–0.656, p < 0.01). Fibrosis showed particularly poor agreement (κ = 0.223–0.496, p < 0.01). Detection of pathology improved with a combination of biopsy techniques, compared to a single biopsy method. Conclusion: Overall diagnosis of NAFLD or NASH shows good agreement between biopsy sites, but individual components, particularly fibrosis stage, vary significantly. Clinicians should consider biopsies from varied sites, to better assess liver disease severity. These data have important implications in fibrosis assessment of NAFLD and are relevant in the interpretation of histological efficacy of investigational pharmacotherapies.
