Abstract Background/aims Some aspects of visual performance worsen with increasing myopia. Whilst the underlying causes are not always clear, reduction in retinal image quality is often attributed to structural changes in the posterior myopic eye. Forward light scatter, originating principally from the cornea and lens, is known to produce veiling glare which subsequently reduces retinal image contrast. It is therefore of interest to investigate whether forward light scatter varies with refractive error. Methods Thirteen young-adult subjects (18–25 years), with mean spherical errors (MSE ± sd, D) RE, − 1.69 ± 2.02 (range 0.38 to − 4.75); LE, − 1.91 ± 1.94 (range 0.50 to − 4.63) underwent binocular assessment of forward light scatter using the AVOT light scatter test. Five glare annuli, with effective eccentricities ranging from 2 to 10°, were used to estimate parameters, k and n, which define the light scatter function of the eye. These were then used to calculate the area under the light scatter function (k′) and the total volume of light scatter (k″). Results Significant correlation was found between increasing myopia and k′ values (RE, p < 0.05; r = 0.64; LE, p < 0.05, r = 0.66). Neither the ‘volume’ of light scatter (k″), the parameter, n, which controls the angular distribution of light scatter, or the straylight parameter constant, k, were significantly correlated with refractive error (p > 0.05 for both eyes). Axial length was also not correlated with any of the light scatter parameters measured. Conclusion The preliminary data from this study provide evidence that some light scatter parameters may be correlated with refractive error. Further studies are needed to characterize how changes in the anterior media of the eye, and inclusion of a wider range of refractive errors, may affect forward light scatter.

Visual performance of human observers depends not only on the optics of the eye and early sensory encoding but also on subsequent cortical processing and representations. In two experiments, we demonstrated that motion adaptation can enhance as well as impair visual acuity. Observers who experienced an expanding motion aftereffect exhibited improved letter recognition, whereas observers who experienced a contracting motion aftereffect showed impaired letter recognition. We conclude that illusory enlargement and shrinkage of a visual stimulus can modulate visual acuity.

<span style="font-size: x-small; font-family: TimesNewRomanPSMT;"><span style="font-size: x-small; font-family: TimesNewRomanPSMT;"><p align="left">Psykisk helsearbeid på internett øker i omfang, og verdsettes på grunn av bekvemmelighet, lave kostnader og muligheter for anonymitet. Artikkelen bygger på en kartlegging av norske og svenske nettbaserte eposttjenester for ungdom og unge voksne, og viser at det var 24 nettsteder som tilbød slike tjenester i 2009. Tjenestene hadde opphav i både offentlig og frivillig sektor. Flesteparten av sidene fra offentlig sektor tok utgangspunkt i eksisterende tjenestetilbud, og var en videreutvikling av tjenestene for å styrke tilgjengeligheten av psykisk helsetjenester. Andre sider oppsto som en konsekvens av FNs konvensjon av barns rettigheter. Størsteparten av sidene fra frivillig sektor ble utviklet som følge av et personlig og/eller fagpolitisk engasjement. Fire hovedtema for e-posttjenestene ble identifisert: 1) Kropp, kjønn og seksuell helse; 2) Informasjon og kontakt med voksne; 3) Rus og rusmidler; 4) Psykiske problemer. Studien viser at nettjenestene argumenterer for at det er viktig for ungdoms psykiske helse at de blir inkludert og akseptert i et fellesskap og at de opplever å bli respektert på egne premisser. Samtidig videreføres et ideal om det uavhengige og autonome mennesket, og nettjenestene formidler samlet sett et spenningsfylt budskap om at ungdom er avhengige av andre for å bli og forbli uavhengige individer. Psykisk helsearbeid på internett framstår som en måte å håndtere denne spenningen på, og muliggjør at ungdom kan håndtere en identitet som både avhengige og uavhengige mennesker. Studien viser forskjeller knyttet til begrepsforståelse, og peker på viktigheten av å utforske meningsinnholdet i psykisk helse nærmere.</p><p align="left">Mental health services on the Internet.<br />ENGLISH SUMMARY: The demand for Internet-based mental health services are increasing. The services are valued for their convenience, low cost and opportunities for anonymity. This article is based on a survey of Norwegian and Swedish Internet-based email services for adolescents and young adults. The objective was to explore the ways in which these services mould young people's view on normality and identity and how they contribute to mental health. 24 websites were systematically reviewed. Most of the sites from public sector derived from existing services and can best be understood as an attempt to enhance the availability of the same services for adolescents and young adults. Other sites were closely connected to the UN Convention of children’s rights. A majority of the services from voluntary sector were developed as a result of initiatives taken by professionals or private persons. The email services focused different issues. A qualitative content analysis identified four main themes: 1) Body, gender and sexual health, 2) Information and contact with adults, 3) Drugs and substance abuse, 4) Mental problems.<br />In order to contribute to mental health amongst adolescents and young adults the services emphasise the importance of social inclusion and acceptation. At the same time the services maintain an ideal of the independent and autonomous human being. The services send out a message stating that young people are dependent on others to become and remain independent persons. Internet-based mental health services<br />enables young people to deal with an identity as both dependent and independent. The study reveals differences regarding the concept of mental health, and emphasise the importance of exploring the concept and meaning of mental health more closely.</p></span></span>

At the end of the day, being alive becomes the topmost priority for anyone in their life span. We can usually see more road tragedies than any good things happening around us. There are many people who lose their precious lives after accidents due to no proper ambulance facility, no one to communicate about the accident to the hospitals or majorly due to getting stuck in the traffic of big cities. The ACCIOUR-IoT based system helps to overcome these problems. Initially, each vehicle will have a device which activates soon after an accident takes place and sends the location to the close ones and to the main server that holds the information of various nearby ambulances, and hence forwards the location to the ambulance. Ambulance on getting the information can turn on their devices that help the traffic signals along their route to know there’s emergency and hence to clear the traffic as much as possible by turning on their green lights immediately so that the patient is taken from the accident spot and later admitted to hospital within the short duration that is possible. On the way, the ambulance will take a quick check on the patient and send information regarding their present condition even before they reach the hospital so that the hospital doctors are aware of what kind of treatment that has to be provided to the patient who is on the way to their hospital. This system majorly challenges the methodology that is currently adopted and provides a better solution to overcome their limitations. Overall, ACCIOUR system is all about saving a precious life and the lives of many others who are indirectly connected to them through technology. spacing.

Carotenoids are natural antioxidants, affecting apoptosis, absorbing active forms of oxygen, and improving visual performance through their blue light filtering capabilities. Lutein and zeaxanthin are carotenoids of the macular pigment that play a significant role in protecting against age-related macular degeneration (AMD), cataracts, and diabetic retinopathy. We analyzed the dietary sources of lycopene, lutein, and zeaxanthin of young adults living in a megapolis. We analyzed 431 food frequency questionnaires and used two different criteria for comparison: age (groups A1 and A2) and season (groups S1, spring, and S2, autumn). Raw red tomatoes and eggs are the main sources of carotenoids for the majority of respondents regardless of age and season. Significant differences between age groups were found for parsley, carrot, cheeseburger, and spring onion. Foods with high levels of carotenoids (tomato juice, pumpkin, spinach, and sprouts) were absent in the diets of most of the study participants. Watermelons and persimmons are seasonal sources of lycopene, lutein, and zeaxanthin. Dietary sources of carotenoids are present in insufficient quantities in the diets. Foods with high levels of lycopene, lutein, and zeaxanthin are absent or only occasionally included in the diet.
