The research aimed to install adequate light fixtures which guide people to higher ground and provide them with the safety and comfort in daily life. The lighting design was examined based on the knowledge of several field surveys and previous researches. Finally, a total of 179 lights, such as incandescent bulbs were attached. The questionnaire survey to residents was carried out before or after the lighting installation. As a result, it was confirmed that the recognition of entrances to evacuate or the evacuation directions which guide to higher ground had increased enough compared with the previous situation. It was also confirmed in the temporary shopping district or the construction office that surrounding visibility and safety had been improved by lighting. The lighting social experiment was conducted over September 2013 to about one month. Most light fixtures have been continuously maintained by residents even after the end of the experiment.","PeriodicalId":311488,"journal":{"name":"Journal of Light & Visual Environment","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129481075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For that reason, LED floodlights, which achieve higher light flux and longer service life than those of the conventional HID floodlights with about half the power consumption, are introduced. LED floodlights are equipped with high-heat-dissipation and high-output LED modules for high light flux, and their improved maintainability that is realized by the initial illuminance correction function and long service life provides energy savings. In addition, they are capable of instant lighting and relighting, which were not possible with HID equipment, so that they can cover a wider range of applications. Furthermore, a lighting control system has been employed for the capability to control various lighting patterns such as 1,000 lx and 500 lx. As a result, the Todoroki Athletic Stadium provides an illuminated space with a high-quality visual environment that allows football players and track and field athletes to play comfortably and vibrantly and spectators to watch plays with comfort.","PeriodicalId":311488,"journal":{"name":"Journal of Light & Visual Environment","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127070477","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The color calibration with the Skin chart worked better than that with a standard color chart. A conventionally obtained photo-image of the pressure ulcer (PU) in medical facilities can be translated into a standard photo-image taken in the standard lighting. The present method is more convenient compared with the previously reported systems using the commercially available color charts. Accordingly, the method successfully identified the involved areas from the healthy skin areas by the color image. The newly developed method is a useful tool for the color image acquisition using conventional digital cameras for the electronic medical recording systems and for the medical consulting network by the information communication technologies (ICTs). The developed color calibration method enables simple, easy, rapid, and less expensive record for the shapes of PUs and the quantitative color distribution of the widely involved areas. Thus, this system is expected as an evaluation tool for the topical therapies for PUs in future.","PeriodicalId":311488,"journal":{"name":"Journal of Light & Visual Environment","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115608675","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted a subjective experiment on the appearance of a woman ʼ s face with make-up. We created spectral distributions by adding or cutting a speciﬁc wavelength on a ﬂat spectral distribution with a wavelength programmable light source. We set up 53 kinds of lighting conditions with different spectral distributions in total. We measured the skin color of the face of the female model, and transformed measured chromaticity values into RGB values of a calibrated LC-display for generating the digital images of the lower half of the face. Twenty female participants observed the cheek illuminated by one of lights with different spectral distributions and evaluated the “ naturalness ” , “ activity ” , “ sophistication ” , “ health ” , “ familiarity ” and “ preference ” of the face. The results show that the lighting including the spectral component of 534 nm makes look the women ʼ s skin worst, and the preference of women ʼ s face can be explained with three aspects, naturalness, activity and sophistication.","PeriodicalId":311488,"journal":{"name":"Journal of Light & Visual Environment","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-03-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121946935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
