| Abstract |
Tunnel lighting installations function 24 h a day, 365 days a year. These infrastructures have increased exponentially and now connect quite distant locations, even on different continents. This has led European administrations and international regulatory bodies to establish regulations for tunnel safety with the lowest environmental impact. However, until now, these regulations have almost exclusively focused on traffic safety, and relegated sustainability to the background. Even though they recognize the need to reduce energy consumption, they do not propose any tools for doing so. Given the impact of these installations and the lack of a specific regulatory framework, Asian countries will soon be forced either to update previous standards for tunnel lighting or elaborate new ones. A better understanding of the weaknesses of European regulations combined with a willingness to embrace innovation could position Asia as a world leader in the regulation of more sustainable road tunnels. The objective of this research was to improve the sustainability of tunnel lighting installations through new regulations or amendments to existing ones, without impairing the mental well-being of users, who could potentially be affected by energy-saving measures. Accordingly, this paper presents and analyzes a broad proposal for formulating tunnel lighting regulations. The originality of this proposal lies in the fact that it integrates road safety, lower environmental impact, and user well-being. Furthermore, it is expected to broaden the perspective of regulatory bodies and public administrations with regard to tunnel installations, which would ultimately enhance their sustainability. |

| Abstract |
The present study aimed to explore the difference in the expression profiles of ovarian microRNA sequences in rats in a light pollution environment and rats in a normal light environment. Rats in the control group were exposed to 12h light/dark cycles, while rats in the model group were continuously exposed to 24h light. The ovaries were extracted from the two groups of rats, and Illumina HiSeq 2500 highthroughput sequencing technology was used to detect the differences in microRNA (miRNA) expression among the two groups. Fluorescence quantitative reverse transcriptionpolymerase chain reaction was used to verify the differential expression of miRNA. The present study was designed to experimentally validate the interaction between miR4215p and mitogenactivated protein kinase (MAPK) 7 by using the dualluciferase reporter system, and to explore the expression of proteins in the MAPK signaling pathway with a lentiviral vectormediated small hairpin RNA interference against microRNA4215p. The expression of 45 miRNAs was significantly different. In total, 13 miRNAs were upregulated, of which 5 miRNA sequences were known and 8 were predicted. Furthermore, 32 miRNAs were downregulated, of which 11 miRNA sequences were known and 21 were predicted. The results of the luciferase reporter assay confirmed the targeting association between miR4215p and MAPK7. The expression levels of MAPK and genes in its downstream signaling pathways, including cFos, CREB and cMyc, were downregulated when miR4215p was overexpressed and upregulated when miR4215p was silenced. The differential expression of miRNAs may serve an important role in the development of the ovary in a light pollution environment. miR4215p may regulate ovarian growth and development by targeting the MAPK signaling pathway in light polluted rat ovaries. |

| Abstract |
In recent years, people have become increasingly attentive to light pollution influences on their eyes. In the visible spectrum, short-wave blue light with wavelength between 415 nm and 455 nm is closely related to eye light damage. This high energy blue light passes through the cornea and lens to the retina causing diseases such as dry eye, cataract, age-related macular degeneration, even stimulating the brain, inhibiting melatonin secretion, and enhancing adrenocortical hormone production, which will destroy the hormonal balance and directly affect sleep quality. Therefore, the effect of Blu-rays on ocular is becoming an important concern for the future. We describe blue light's effects on eye tissues, summarize the research on eye injury and its physical prevention and medical treatment. |

| Abstract |
This study was used two detectors only i.e., the human eye and photometer of Sky Quality Meter (SQM-LU) during the time of sunrise and sunset. The human eye used to determine the moon's phase. The measurements of sky brightness, by using SQM-LU, performed via two locations that covered Baghdad and Karbala in Iraq from December 2016 through March 2017 intermittently. The research focused only on light perceived by detectors and not how it happens. The aim of research is to find a mathematical formula (i.e . brightness contrast) between the sky brightness against the solar altitude by taking moon illumination as the standard reference. Analytical software based on the Python's PyEphem astrometry library was developed to calculate the solar altitude at the two locations. Finally, the formula of sky brightness obtained from this work is an important key that contributed to finding the simulated sky brightness, when the sun's altitude is known. |

| Abstract |
The lighting of the Church of the Three Kings in Logatec, Slovenia was replaced in 2014. The power of the installation was reduced 96% from 1.6 kW to 58 W, and spill light from the site was effectively eliminated. As a result, the church is no longer visible in nighttime satellite images of the area, indicating a reduction of waste light from the site of at least a factor of 30. This article discusses the concept of sustainability with regards to cultural heritage lighting, within the context of this example. |
