Title Media Prophylaxis: Night Modes and the Politics of Preventing Harm Type Journal Article
Year 2018 Publication Information & Culture Abbreviated Journal Information & Culture
Volume 53 Issue 2 Pages 175-202
Keywords Human Health; Society
Abstract This article develops the term “media prophylaxis” to analyze the ways technologies are applied to challenges of calibrating one’s body with its environment and as defenses against endemic, human-made harms. In recent years, self-illuminated screens (like those of computers, phones, and tablets) have been identified by scientists, journalists, and concerned individuals as particularly pernicious sources of sleep-disrupting light. By tracing the history of circadian research, the effects of light on sleep patterns, and the recent appearance of software like “f.lux,” Apple’s “Night Shift,” and “Twilight,” this article shows how media-prophylactic technologies can individualize responsibility for preventing harm while simultaneously surfacing otherwise ignored forms of chronic suffering.

Title Effect of Late Night Studying and Excessive Use of Video Display Terminals on the Ocular Health of Medical Undergraduate Students in A Tertiary Care Hospital Type Journal Article
Year 2018 Publication Journal of Clinical & Experimental Ophthalmology Abbreviated Journal J Clin Exp Ophthalmol
Volume 09 Issue 06 Pages
Keywords Human Health
Abstract Purpose: To evaluate the effect of late night study and excessive use of smart phones on the ocular health of medical undergraduate students.

Design: An observational and cross-sectional study.

Participants: Two hundred and fifty nine normal and healthy M.B.B.S students of age 18-25 y were included in the study over a period of two months.

Methods: All the volunteers underwent an interview in form of a questionnaire. A complete ophthalmic examination was done including snellen visual acuity assessment, anterior segment examination with slit lamp, posterior segment with direct or indirect ophthalmoscopy; Schirmer’s test and tear film break up time.

Results: A total of 259 subjects were included in the study and maximum subjects 160 (61.8%) were females. According to age, the students were divided in two groups as I and II with age of 17-20 y and 21-23 y respectively. Maximum 195 (75.3%) students belonged to group I. Maximum subjects 245 (94.5%) were using only smartphones and 239 (92.27%) subjects were using smartphones for more than 2 y. The maximum 136 (52.51%) students studied at night with maximum using tube light 112 (43.24%). A significant association was seen between the digital device used and age of the subject (p value=0.01). Number of symptoms experienced by the students showed significant relationship with the number of hours of smartphone usage (p value=0.02). Source of light in which the students studied at night was significantly associated with the number of symptoms experienced (p value=0.03). An association between usage of smartphones (hours) showed significant relationship with slit lamp examination (tear debri) and Schirmer’s (less than 15 mm) with p value of 0.03, 0.05 respectively.

Conclusion: Source of light used to study at night and number of hours of use of devices shows relationship with symptoms. Smart phone users showed computer-related eye problems in more than half of the subjects.

Title Illuminance Reconstruction of Road Lighting in Urban Areas for Efficient and Healthy Lighting Performance Evaluation Type Journal Article
Year 2018 Publication Applied Sciences Abbreviated Journal Applied Sciences
Volume 8 Issue 9 Pages 1646
Keywords Instrumentation; Lighting; Planning
Abstract Big lighting data are required for evaluation of lighting performance and impacts on human beings, environment, and ecology for smart urban lighting. However, traditional approaches of measuring road lighting cannot achieve this aim. We propose a rule-of-thumb model approach based on some feature points to reconstruct road lighting in urban areas. We validated the reconstructed illuminance with both software simulated and real road lighting scenes, and the average error is between 6 and 19%. This precision is acceptable in practical applications. Using this approach, we reconstructed the illuminance of three real road lighting environments in a block and further estimated the mesopic luminance and melanopic illuminance performance. In the future, by virtue of Geographic Information System technology, the approach may provide big lighting data for evaluation and analysis, and help build smarter urban lighting.
