The transmission spectra of fabricated nanocavities were measured using the spectroscopic ellipsometer (J. A. Woollam Co., V-VASE). The light source is a xenon lamp with a broadband Visible to NIR spectrum. The diameter of the incident beam was set to be 400 μm. The beam sequentially passed through a monochromator, a polarizer, and it is used to expose the sample, and then it’s collected by a detector. The colour image was captured with simple optical set-up. The white lamp was used as light source and linear polarizer was placed between lamp and sample. The image was captured with commercial camera in mobile phone (Samsung Galaxy S3) with ×4 magnification. ISO was set to 100, auto-contrast was off, and the micro lens was attached to camera.

Fieldworkers trained using study-specific standardized operating procedures attended the homes of all participating children to interview their parents or guardians at the baseline data collection visit for CAPS. Electronic Case Report Forms (CRFs) programmed using Open Data Kit (ODK) software and administered offline using smart phones (Samsung Galaxy S3, Samsung, Seoul, Korea) were used to collect data. Demographic, socioeconomic, health and household air pollution data were collected in this way at enrolment. An additional questionnaire was administered at the time of collection of CO monitors (see below) about potential smoke exposures and cooking practices including number of meals, fuel used and cooking location during the time CO monitors were worn.

Study participants were exposed to two VR environments: scenery, where the participant is exposed to a VE consisting of passive sceneries such as nature experiences; and somatic, where the VE consisted of upper and lower extremity movements (Figure 1). Two types of somatic environments were used, and participants chose the most appropriate environment based upon their self-reported location of their most prominent pain: an upper extremity VE or a lower extremity VE. While viewing the VEs, no specific commands were given, and participants were not encouraged to focus on any particular part or element of the VE. Patients underwent the two consecutive VR sessions (scenery and somatic) in a randomized order. Each VR session was 10 min in duration. The participant was permitted to leave the laboratory and move freely within the campus (in some cases for several hours) and return for the second VR session once the participant reported a return to baseline pain level.
The VR system consisted of the Samsung Galaxy S3 housed in a Samsung Gear VR headset (Figure 1). Patients were placed in a seated position on a chair or their personal wheelchair, with the ability to look around freely. Patients were instructed to report any discomfort and given the possibility to ask to stop the intervention at any time.
