Purpose The main purpose of this study was to evaluate aging effects on the predominantly subcortical (brainstem) encoding of the second-formant frequency transition, an essential acoustic cue for perceiving place of articulation. Method Synthetic consonant–vowel syllables varying in second-formant onset frequency (i.e., /ba/, /da/, and /ga/ stimuli) were used to elicit speech-evoked auditory brainstem responses (speech-ABRs) in 16 young adults ( M age = 21 years) and 11 older adults ( M age = 59 years). Repeated-measures mixed-model analyses of variance were performed on the latencies and amplitudes of the speech-ABR peaks. Fixed factors were phoneme (repeated measures on three levels: /b/ vs. /d/ vs. /g/) and age (two levels: young vs. older). Results Speech-ABR differences were observed between the two groups (young vs. older adults). Specifically, older listeners showed generalized amplitude reductions for onset and major peaks. Significant Phoneme × Group interactions were not observed. Conclusions Results showed aging effects in speech-ABR amplitudes that may reflect diminished subcortical encoding of consonants in older listeners. These aging effects were not phoneme dependent as observed using the statistical methods of this study.

Abstract. We report the results of a meta-analysis of 22 experiments comparing the eye movement data obtained from young ( Mage = 21 years) and old ( Mage = 73 years) readers. The data included six eye movement measures (mean gaze duration, mean fixation duration, total sentence reading time, mean number of fixations, mean number of regressions, and mean length of progressive saccade eye movements). Estimates were obtained of the typified mean difference, d, between the age groups in all six measures. The results showed positive combined effect size estimates in favor of the young adult group (between 0.54 and 3.66 in all measures), although the difference for the mean number of fixations was not significant. Young adults make in a systematic way, shorter gazes, fewer regressions, and shorter saccadic movements during reading than older adults, and they also read faster. The meta-analysis results confirm statistically the most common patterns observed in previous research; therefore, eye movements seem to be a useful tool to measure behavioral changes due to the aging process. Moreover, these results do not allow us to discard either of the two main hypotheses assessed for explaining the observed aging effects, namely neural degenerative problems and the adoption of compensatory strategies.

Abstract. West Java Provincial Health Office still faces difficulties in managing information, especially in medical records. Recording and reporting of malnutrition are still done in some stages starting from collecting data from village midwives, puskesmas, Regency/City Health Office then Provincial Health Office and forwarded to the the central office. It is necessary to manage information through service system by utilizing Cloud Computing based on information technology. This research uses The Open Group Architecture Framework (TOGAF) approach in Architecture Development Method (ADM), from Architecture Capability Iteration to  Architecture Development Iteration. Monitoring and Evaluation (M & E) are two integrated activities in the context of controlling a program. The results of this research are planning a medical record information system architecture and monitoring malnutrition based on Cloud Computing with the name of M2Rec (Medical Record and Monitoring) in the form of integrated recommendation and development between current information system and proposed information system architecture.Keywords: togaf adm, medical record and monitoring, cloud computing Abstrak. Perencanaan Arsitektur Sistem Informasi Rekam Medis dan Monitoring Gizi Buruk Berbasis Cloud Computing. Dinas Kesehatan Propinsi Jawa Barat masih mengalami kesulitan dalam pengelolaan informasi yang baik, terutama pada proses rekam medis, pencatatan dan pelaporan gizi buruk masih dilakukan secara bertingkat mulai pengumpulan data dari bidan desa, puskesmas, Dinas Kesehatan Kabupaten/Kota kemudian Dinas Kesehatan Propinsi dan diteruskan ke pusat. Sehingga perlu diupayakan pengelolaan informasi melalui sistem pelayanan dengan memanfaatkan teknologi informasi berbasis Cloud Computing. Penelitian ini menggunakan pendekatan framework The Open Group Architecture Framework (TOGAF) Architecture Development Method (ADM), yaitu iterasi ke satu pada Architecture Capability Iteration daniterasi ke dua pada Architecture Development Iteration. Monitoring dan Evaluasi (M&E) merupakan dua kegiatan terpadu dalam rangka pengendalian suatu program. Hasil dari penelitian ini adalah perencanaan arsitektur sistem informasi rekam medis dan monitoring gizi buruk berbasis Cloud Computing dengan nama M2Rec (Medical Record and Monitoring) yang berupa rekomendasi integrasi dan pengembangan antara sistem informasi berjalan saat ini dengan arsitektur sistem informasi yang diusulkan.Kata kunci: togaf adm, medical record and monitoring, cloud computing.
