Authors: Alawiyah Tuti 
Published: September 2018

Penelitian ini mengkaji tentang bagaimana penerimaan informasi melalui media pembelajaran digital talking book untuk siswa tunanetra. Penerimaan informasi pada intinya adalah mengubah pesan ke dalam bentuk yang dapat digunakan untuk memandu perilaku manusia. Proses penerimaan informasi terdiri dari tiga elemen, yaitu penyeleksian informasi, interpretasi informasi, dan retensi informasi. Penelitian dilakukan dengan menggunakan metode studi kasus. Informan adalah salah satu siswa tunanetra di MTsN 19 Jakarta. Sekolah ini adalah salah satu sekolah inklusi, sekolah yang memberikan layanan pendidikan yang menyertakan semua anak termasuk siswa berkebutuhan khusus, salah satunya siswa tunanetra dengan metode pembelajaran yang sama. Hasil penelitian menunjukkan bahwa penerimaan informasi melalui digital talking book di kalangan siswa tunanetra mempunyai tantangan tersendiri. Dalam tahapan penyeleksian informasi, informan menggunakan sumber informasi dari braille dan digital talking book secara bergantian sesuai dengan kebutuhan. Perbedaan cara mengakses dari braille (indera peraba) menjadi digital talking book (indera pendengaran) menjadi persoalan tersendiri. Selain itu, dibutuhkan kemampuan khusus untuk menguasai tombol-tombol navigasi pada alat pemutar digital talking book. Dalam tahapan interpretasi informasi, informan menafsirkan konten digital talking book dibantu dengan catatan dalam huruf braille. Dalam tahapan retensi memori, informan mampu mengingat secara baik informasi yang bersifat sementara, seperti kata-kata istilah, angka-angka, dan penjelasan tentang definisi, namun memiliki keterbatasan untuk memori jangka panjang sehingga membutuhkan waktu yang lebih lama. Faktor-faktor yang mempengaruhi penerimaan informasi, di antaranya tujuan, cara bagaimana pesan itu disampaikan, dan peran keluarga. Dalam proses penerimaan informasi melalui digital talking book, pilihan untuk tetap menggunakan braille cukup tinggi. Kecenderungan informan untuk memilih untuk menggunakan braille dibandingkan dengan digital talking book karena dianggap lebih mudah, ekonomis, dan cepat, merasa berinteraksi langsung dengan tulisan, danÂ indera peraba dapat optimal digunakan sehingga mengingat lebih cepat.
ÂŞIK PAŞA’YA MAL EDİLEN YENİ BİR YÛNUS EMRE GAZELİ ÜZERİNE

Published: September 2018

Klasik Edebiyatımızın problemli
meselelerinden olan, bir manzumenin başka şairlere mal edilmesi durumu, belki
de en fazla Yûnus Emre’nin şiirlerinde görülmektedir. Yûnus mahlaslı pek çok
manzumenin Yûnus Emre’ye mal edildiği bilinmektedir. Bununla birlikte, Yûnus’un
da bazı manzumeleri başka şairlere isnat edilmiştir.

Bu çalışmada Âşık Paşa’ya mal edilen bir
Yûnus Emre gazeli üzerinde durulacaktır. Garib-nâme adlı eseriyle şöhret bulmuş
olan Âşık Paşa’nın dağınık halde bulunan 54 şiiri tespit edilmiştir. Bu
şiirlerden bazıları Egridirli Hacı Kemâl’in Câmiü’n-Nezâir adlı eserinde yer
almaktadır. Buradaki şiirlerinden bazılarının başka şairlere ait olduğu tespit
edilen Âşık Paşa’nın, araştırmacıların gözden kaçırdığı bir manzumesi daha
vardır. Söz konusu gazel, Nesîmî’ye nazire olarak gösterilmiş olup Miskin
mahlası ile kayıtlıdır.

Dikkatlerden kaçan Âşık Paşa’ya isnat
edilen bu gazel, aslında Yûnus Emre’ye aittir. Aralarında zaman farkı olduğunu
için Âşık Paşa’nın Nesîmî’ye nazire yazma ihtimali bulunmamaktadır. Miskin
mahlasını Âşık Paşa değil Yûnus Emre kullanmıştır. Ayrıca Marmara Üniversitesi
İlahiyat Fakültesi kütüphanesinde bulunan 08802/HS0753 demirbaş numarasıyla
kayıtlı bir “Mecmuatü’l-Eş’ar” içinde bu gazelin Yûnus Emre adına kayıtlı
olduğu tespit edilmiştir. Yine 18. asır şairlerinden Ali Senâyî’nin bu gazele bir
tahmisi mevcuttur. Gazelin Yûnus’a ait olduğu Ali Senâyî tarafından da ifade
edilmiştir. Gazelin üslup özellikleri de Âşık Paşa’dan ziyade Yûnus’un
şiirlerindeki üslup ile benzerlikler göstermektedir. Bütün bu deliller
ışığında, gazelin Yûnus Emre’ye ait olduğu anlaşılmıştır.

Published: September 2018

<p>This study was designed to understand whether the post-menopausal Chinese women (n=175) receiving tablet containing vitamin D (500 IU) and calcium (500 mg) had lower incidence of bone fracture compared to the post-menopausal Chinese women ((n=175) receiving a diet rich in calcium, vitamin D, and protein (milk, cheese, and yogurt, soybeans, spinach, fish including fatty fish, cheese, egg). This study assessed whether the levels of serum osteocalcin and urinary free deoxypyridinoline could be used as predictors of early bone trauma during post-menopausal period. After randomization, subjects were followed-up for up to 3 years to capture required data. The results suggested that therapeutic intervention (vitamin D and calcium) does not predict bone fracture among the post-menopausal Chinese women. However, correlation analysis revealed that the decreased level of serum osteocalcin and urinary free deoxypyridinoline were associated with higher incidence of fracture. The results suggest that the low level of serum osteocalcin and urinary free deoxypyridinoline cause increase susceptibility of fracture among the post-menopausal Chinese women.</p>

Abstract
Double detonations in double white dwarf (WD) binaries undergoing unstable mass transfer have emerged in recent years as one of the most promising Type Ia supernova (SN Ia) progenitor scenarios. One potential outcome of this “dynamically driven double-degenerate double-detonation” (D6) scenario is that the companion WD survives the explosion and is flung away with a velocity equal to its >1000 km s−1 pre-SN orbital velocity. We perform a search for these hypervelocity runaway WDs using Gaia's second data release. In this paper, we discuss seven candidates followed up with ground-based instruments. Three sources are likely to be some of the fastest known stars in the Milky Way, with total Galactocentric velocities between 1000 and 3000 km s−1, and are consistent with having previously been companion WDs in pre-SN Ia systems. However, although the radial velocity of one of the stars is >1000 km s−1, the radial velocities of the other two stars are puzzlingly consistent with 0. The combined five-parameter astrometric solutions from Gaia and radial velocities from follow-up spectra yield tentative 6D confirmation of the D6 scenario. The past position of one of these stars places it within a faint, old SN remnant, further strengthening the interpretation of these candidates as hypervelocity runaways from binary systems that underwent SNe Ia.
Relativistic Tidal Disruption and Nuclear Ignition of White Dwarf Stars by Intermediate-mass Black Holes
Authors: Anninos Peter , Fragile P. Chris , Olivier Samuel S. , Hoffman Robert , Mishra Bhupendra , Camarda Karen 
Published: September 2018

Abstract
We present results from general relativistic calculations of the tidal disruption of white dwarf stars from near encounters with intermediate-mass black holes. We follow the evolution of 0.2 M
⊙ and 0.6 M
⊙ stars on parabolic trajectories that approach 103–104
M
⊙ black holes as close as a few Schwarzschild radii at periapsis, paying particular attention to the effect that tidal disruption has on thermonuclear reactions and the synthesis of intermediate-mass to heavy elements. These encounters create diverse thermonuclear environments that are characteristic of Type I supernovae and capable of producing both intermediate-mass and heavy elements in arbitrary ratios, depending on the strength (or proximity) of the interaction. Nuclear ignition is triggered in all of our calculations, even at weak tidal strengths β ∼ 2.6 and large periapsis radius R
P ∼ 28 Schwarzschild radii. A strong inverse correlation exists between the mass ratio of calcium-group to iron-group elements and tidal strength, with β ≲ 5 producing predominantly calcium-rich debris. At these moderate to weak interactions, nucleosynthesis is not especially efficient, limiting the total mass and outflows of calcium-group elements to <15% of available nuclear fuel. Iron-group elements, however, continue to be produced in greater quantity and ratio with increasing tidal strength, peaking at ∼60% mass conversion efficiency in our closest encounter cases. These events generate short bursts of gravitational waves with characteristic frequencies 0.1–0.7 Hz and strain amplitudes from 0.5 × 10−22 to 3.5 × 10−22 at a source distance of 10 Mpc.

Authors: She Kaiqin , Zhang Qi , Fei Ping , Peng Jie , Lyu Jiao , Li Yian , Huang Qiujing , Zhao Peiquan 
Published: September 2018

BACKGROUND AND OBJECTIVE:
To report the association of morning glory syndrome (MGS) with peripheral retinal nonperfusion in pediatric patients with MGS.

PATIENTS AND METHODS:
The authors retrospectively analyzed the records of pediatric patients with MGS using fundus fluorescein angiography. The peripheral retinal vascular architecture was recorded and graded according to the severity of peripheral retinal nonperfusion.

RESULTS:
Eighty-six eyes of 74 patients were enrolled. Seventy-three of 86 eyes (84.88%) had peripheral retinal nonperfusion, in which mild severity was found in 31 of 86 eyes (36.05%), moderate in 17 of 86 eyes (19.77%), severe in 18 of 86 eyes (20.93%), and extreme in seven of 86 eyes (8.14%). Secondary complications of nonperfusion included leakage in six of 73 eyes (8.22%), fibrovascular proliferation in two of 73 eyes (2.74%), and tractional retinal detachment in one of 73 eyes (1.34%).

CONCLUSION:
There is a high prevalence of peripheral retinal nonperfusion in pediatric MGS eyes, with secondary complications in some, suggesting that more attention should be paid to the peripheral retina in MGS.

Post-Traumatic Giant Retinal Tear Without Posterior Vitreous Detachment: A Case Series
Authors: Savastano Alfonso , Barca Francesco , Tartaro Ruggero , Caporossi Tomaso , Rizzo Stanislao 
Published: September 2018

BACKGROUND AND OBJECTIVE:To investigate the vitreal condition in retinal detachment (RD) related to giant retinal tears (GRT) after ocular blunt trauma.PATIENTS AND METHODS:Retrospective, observational study conducted at Azienda Ospedaliera Universitaria Careggi, Florence, Italy. The institutional review board and ethics committee approved the study. Records of 23 eyes of 23 patients affected by traumatic RD associated with a GRT were evaluated. A total of four eyes had RD related to blunt trauma, in which the authors performed 25-gauge vitrectomy and silicone oil was used as a endotamponade.RESULTS:Three out of four eyes did not display a posterior vitreous detachment at the B-scan, and this was confirmed during surgery. The three eyes had a mean visual acuity of 20/32 1 month after silicone oil removal.CONCLUSIONS:Posterior vitreous detachment may not be present in RD associated with GRT after blunt trauma. This knowledge could result in modified intraoperative management to improve postoperative outcomes.[Ophthalmic Surg Lasers Imaging Retina. 2018;49:686–690.]
Visual Acuity Outcomes in Diabetic Macular Edema With Fluocinolone Acetonide 0.2 μg/Day Versus Ranibizumab Plus Deferred Laser (DRCR Protocol I)
Authors: Singer Michael A. , Miller Dan M. , Gross Jeffrey G. , Greven Craig M. , Kapik Barry , Bailey Clare , Ghanchi Faruque , Kuppermann Baruch D. 
Published: September 2018

BACKGROUND AND OBJECTIVE:
Visual outcomes of the FAME study (0.2 μg/day fluocinolone acetonide [FAc]) and Protocol I (0.5 mg ranibizumab plus deferred laser) were compared using the area under the curve (AUC) analysis method.

PATIENTS AND METHODS:
Best-corrected visual acuity (BCVA) data collected during a period of 3 years of follow-up for patients enrolled in FAME or Protocol I were used to calculate AUC of the change in BCVA over a time curve.

RESULTS:
In the overall population, there was a greater treatment effect for ranibizumab plus deferred laser compared with FAc. However, for subgroups of pseudophakic eyes, eyes with chronic diabetic macular edema (DME), and pseudophakic eyes with chronic DME, ranibizumab plus deferred laser and FAc were not found to be significantly different. The ranibizumab group received a median of 14 injections during a 36-month period compared with a mean of 1.3 injections in the FAc group.

CONCLUSION:
In pseudophakic and chronic DME subgroups, FAc was comparable to ranibizumab plus deferred laser with fewer injections.

Repeatability of Split-Spectrum Amplitude-Decorrelation Angiography to Assess Capillary Perfusion Density Within Optical Coherence Tomography
Authors: Conti Felipe F. , Young Jason M. , Silva Fabiana Q. , Rodrigues Eduardo B. , Singh Rishi P. 
Published: September 2018

BACKGROUND AND OBJECTIVE:
To evaluate the repeatability of retinal thickness and vascular density measurements using split-spectrum amplitude-decorrelation angiography (SSADA) with optical coherence tomography (OCT).

PATIENTS AND METHODS:
Forty patients were divided into seven categories according to their diagnosis: no retinopathy (control), retinal vein occlusion, diabetes with no retinopathy, diabetes with retinopathy, non-exudative age-related macular degeneration (AMD), exudative AMD, and epiretinal membrane. Capillary density and retinal thickness measurements were taken and evaluated for reliability by determination of statistically significant differences and coefficient of variability (CoV) between measurements.

RESULTS:

No significant differences (
P
> .05) were found in any of the within-visit measurements. CoVs ranged from 0.26% to 52.76%, depending on the measure and the disease settings.

CONCLUSION:
The SSADA OCT angiography analysis has a low level of variability between measurements and, thus, is a reliable tool for evaluation of retinal perfusion.

A Retrospective Analysis of the Timing of Initial Treatment of Bedside-Screened Versus Photographically Screened Eyes With Retinopathy of Prematurity
Authors: Alapati Akhila , Trese Michael 
Published: September 2018

BACKGROUND AND OBJECTIVE:
A retrospective clinical study was performed to assess whether photographically screened and remotely read images for retinopathy of prematurity (ROP) allowed for timely and accurate diagnosis of treatment-warranted ROP compared to bedside examination.

PATIENTS AND METHODS:
The study included 130 eyes of 65 premature neonates in born at William Beaumont Hospital, Royal Oak NICU. Bedside examined (2006 to 2010) and telemedicine screened (2010 to 2014) neonates were compared to identify whether there is a statistical difference in postmenstrual age (PMA) at the time of treatment.

RESULTS:

One hundred thirty eyes of 65 infants met the inclusion and exclusion criteria. Thirty-five infants who needed laser treatment were screened bedside with an average PMA at treatment of 36.5 weeks. Thirty infants who needed treatment were photographically screened, with an average PMA at treatment of 36.4 weeks. Neither group had statistically different PMAs (
P
= .58).

CONCLUSION:
This study confirms that telemedicine also allows for appropriately timed treatment for early ROP.

Contralateral Autologous Internal Limiting Membrane Transplantation for Closure of a Refractory Macular Hole: Surgical Technique
Authors: Ra Ho , Lee Won Ki 
Published: September 2018

BACKGROUND AND OBJECTIVE:
To determine the efficacy of a new surgical technique involving use of a contralateral autologous internal limiting membrane (ILM) free flap for closure of a refractory macular hole (MH).

PATIENTS AND METHODS:
Closure could not be achieved after several MH surgeries in a 72-year-old woman with an epiretinal membrane (ERM) in the right eye and a chronic MH in the left eye. Therefore, the authors performed surgery on the left eye using a contralateral autologous ILM free flap obtained during ERM surgery performed on the right eye.

RESULTS:
The refractory MH had disappeared, and the patient's corrected visual acuity was improved in both eyes by 4 months after surgery.

CONCLUSION:
When a suitable free flap cannot be obtained from the operated eye, contralateral autologous ILM transplantation has the potential to improve functional and anatomical outcomes in an eye with a refractory MH.
