Kemampuan Literasi Media Visual Siswa dan Keberhasilan Pembelajaran Teknologi Informasi dan Komunikasi (Tik) di SMP Negeri 11 Pare-pare
The aims of this research are to (1) description of the implementation of learning information and communication technology (ICT) at Junior High School 11 Pare-pare, (2) the ability of visual media literacy students of SMP Negeri 11 Parepare, (3) the relationship of visual media literacy skills of students with successful learning of information technology and communication technology (ICT) students of SMP Negeri 11 Parepare. This study uses a qualitative survey. The survey is conducted by selecting information who has targeted the starts from the observation of direct observation, interview and documentation as the main instrument of research. This study focuses on the ability of visual media literacy students in learning information and communication technology (ICT) in Junior High School 11 Parepare state in order to achieve the learning objectives. The result of this research showed an increase in students skills in reading and understanding the flow of information and materials about the technology in the form of visual communication technologies presented by the teacher along with full facilities and a variety of visual presentation shown by the teachers And learning strategies in teaching ICT. Visual media literacy skills students both in teaching and learning easier
Perilaku Aktivasi Coordination Class Oleh Subyek Lintas Level Akademik Dalam Dekonstruksi Physics Jeopardy Problem
Phenomenographic analysis has been done on activation behavior of coordination class, especially causal net by cross-section ability subjects in deconstruction of information through a Jeopardy Problem. Data were obtained from problem solving activities in individual thinking-aloud format. In the deconstruction of graph to physical situation, respondents used the cognitive element as tool in analyzing or reasoning. Activation behavior of the causal net influenced by their prior experience related to the interpretation of graph function y(x) or vector in the x-y plane. The research results support the coordination class theory and emphasize the prior research findings of mental model and cognitive elements as aspects or features of the mental model
Effect of a Physician Uncertainty Reduction Intervention on Blood Pressure in Uncontrolled Hypertensives-A Cluster Randomized Trial
BACKGROUND: Clinical inertia, provider failure to appropriately intensify treatment, is a major contributor to uncontrolled blood pressure (BP). Some clinical inertia may result from physician uncertainty over the patient’s usual BP, adherence, or value of continuing efforts to control BP through lifestyle changes.
OBJECTIVE: To test the hypothesis that providing physicians with uncertainty reduction tools, including 24-h ambulatory BP monitoring, electronic bottle cap monitoring, and lifestyle assessment and counseling, will lead to improved BP control.
DESIGN: Cluster randomized trial with five intervention clinics (IC) and five usual care clinics (UCC).
SETTING: Six public and 4 private primary care clinics.
PARTICIPANTS: A total of 665 patients (63 percent African American) with uncontrolled hypertension (BP ≥140 mmHg/90 mmHg or ≥130/80 mmHg if diabetic).
INTERVENTIONS: An order form for uncertainty reduction tools was placed in the IC participants’ charts before each visit and results fed back to the provider.
OUTCOME MEASURES: Percent with controlled BP at last visit. Secondary outcome was BP changes from baseline.
RESULTS: Median follow-up time was 24 months. IC physicians intensified treatment in 81% of IC patients compared to 67% in UCC (p\u3c0.001); 35.0% of IC patients and 31.9% of UCC patients achieved control at the last recorded visit (p\u3e0.05). Multi-level mixed effects longitudinal regression modeling of SBP and DBP indicated a significant, non-linear slope difference favoring IC (p time × group interaction=0.048 for SBP and p=0.001 for DBP). The model-predicted difference attributable to intervention was −2.8 mmHg for both SBP and DBP by month 24, and −6.5 mmHg for both SBP and DBP by month 36.
CONCLUSIONS: The uncertainty reduction intervention did not achieve the pre-specified dichotomous outcome, but led to lower measured BP in IC patients
Karakteristik Struktur Mikroskopik Lapisan Tipis Bahan Ferromagnetik Ni yang Dideposisi dengan Teknik Magnetoelektrolitik
KARAKTERISTIK STRUKTUR MIKROSKOPIK LAPISAN TIPIS BAHAN FERROMAGNETIK Ni YANG DIDEPOSISI DENGAN TEKNIK MAGNETOELEKTROLITIK. Telah dilakukan deposisi lapisan tipis bahan feromagnetik Ni dengan sistem magnetoelektrolitik di atas substrat PCB (berlapis Cu) dalam larutan NiSO4. Modifikasi alat deposisi dengan penambahan sistem penganil magnetik serta variasi parameter kuat medan magnet dalam interval (0,00-7,79) mT menunjukkan bahwa semua lapisan tipis yang diperoleh kualitas penampilannya baik. Berdasarkan difraktogram, dapat dilihat bahwa interferensi konstruktif terjadi pada sudut rerata (2θ) masing-masing 44,493°; 51,860° dan 76,417°. Dari hasil analisis XRD dapat diketahui bahwa keseluruhan sampel merupakan polikristal berstruktur dasar FCC yang memiliki orientasi bidang hkl [111], [200] dan [220] dengan orientasi yang paling dominan (preferential orientation) terbentuk dengan mantap adalah [200]. Ukuran butir (grain size) bagi krital [200] dengan orientasi tersebut berkisar (175-295)Å. Hasil deposisi dengan sistem magnetoelektrolitik (magnetoelektrodeposisi) memberikan hasil struktur mikroskopik yang lebih baik dibanding sistem elektrodeposisi biasa
