USER INTERFACE UNTUK TAMPILAN WEBSITE BERITA MOBILE BAGI PENYANDANG RABUN DEKAT

Saat ini ada banyak website yang disajikan dalam bentuk mobile, yang menyediakan berbagai informasi kepada pengguna, termasuk di antaranya website berita mobile. Namun, bagi pengguna yang mengalami rabun dekat merasa kesulitan dalam membaca. Peneliti sudah melakukan wawancara terhadap 3 orang yang mengalami rabun dekat dengan rentang usia 30-60 tahun dengan jarak 25-30 cm, dari hasil wawancara menyatakan bahwa orang yang mengalami rabun dekat kesulitan dalam membaca karena font nya, ukurannya, tidak sesuai sehingga tidak terbaca dengan jelas dan informasi tidak di dapat oleh pengguna. Penelitian ini menggunakan metode UCD (User Centered Design), yang mana metode UCD dapat menempatkan pengguna sebagai pusat pengembangan design. Metode ini dapat digunakan untuk mengetahui seperti apa karakter dan kebutuhan dari pengguna. Untuk mengetahui tingkat usability design yang sudah dibuat, dilakukan pengujian dengan penyebaran kuesioner dalam bentuk google form dengan hasil pengujian yang pertama sebesar 79,81 masuk ke dalam kriteria (B) Baik. Kemudian dilakukan pengujian kedua mendapatkan hasil 85,27 dengan iterasi sebanyak dua kali setelah melalui proses UCD. Berdasarkan hasil tersebut, design website berita mobile bagi penyandang rabun dekat termasuk ke dalam kriteria (SB) Sangat Baik

BMP4 Expression Following Stem Cells from Human Exfoliated Deciduous and Carbonate Apatite Transplantation on Rattus norvegicus

Background: Alveolar bone defects in children still have a high incidence. Conventional bone graft technique that has been used as a defect therapy is still not effective, so new techniques with tissue engineering approach are needed. Bone Morphogenetic Protein 4 (BMP4) as one of the indicators of osteogenic differentiation has not been widely studied, especially in the transplantation with combination of Stem Cells from Human Exfoliated Deciduous (SHED) and carbonate apatite. Aim and Objectives: This research aimed to determine the expression of BMP4 after SHED and carbonate apatite transplantation on Rattus norvegicus. Material and Methods: The combinations of SHED and carbonate apatite were transplanted on alveolar bone defects of 4 rats (Rattus norvegicus) as the treatment groups and another 4 rats were transplanted with carbonate apatite as the control groups. After 21 days, staining with Hematoxylin Eosin (HE) and Immunohistochemistry (IHC) BMP4 was performed. Results: BMP4 expression in the treatment groups was significantly higher when compared to the control groups. Discussion: Carbonate apatite has low crystallization rate and high osteoconductivity that produce more osteoblasts and increased BMP4 expression. Conclusion: The transplantation of SHED and carbonate apatite increased BMP4 expression as an indicator of osteogenic differentiation in rats

Health consequences of electric lighting practices in the modern world: A report on the National Toxicology Program's workshop on shift work at night, artificial light at night, and circadian disruption

The invention of electric light has facilitated a society in which people work, sleep, eat, and play at all hours of the 24-hour day. Although electric light clearly has benefited humankind, exposures to electric light, especially light at night (LAN), may disrupt sleep and biological processes controlled by endogenous circadian clocks, potentially resulting in adverse health outcomes. Many of the studies evaluating adverse health effects have been conducted among night- and rotating-shift workers, because this scenario gives rise to significant exposure to LAN. Because of the complexity of this topic, the National Toxicology Program convened an expert panel at a public workshop entitled “Shift Work at Night, Artificial Light at Night, and Circadian Disruption” to obtain input on conducting literature-based health hazard assessments and to identify data gaps and research needs. The Panel suggested describing light both as a direct effector of endogenous circadian clocks and rhythms and as an enabler of additional activities or behaviors that may lead to circadian disruption, such as night-shift work and atypical and inconsistent sleep-wake patterns that can lead to social jet lag. Future studies should more comprehensively characterize and measure the relevant light-related exposures and link these exposures to both time-independent biomarkers of circadian disruption and biomarkers of adverse health outcomes. This information should lead to improvements in human epidemiological and animal or in vitro models, more rigorous health hazard assessments, and intervention strategies to minimize the occurrence of adverse health outcomes due to these exposures
