Therapeutic lighting design for the elderly: a review

This article is closed access, it will be published in the journal, Perspectives in Public Health [Sage Publications © Royal Society for Public Health]. The definitive version is available at: http://dx.doi.org/10.1177/1757913911422288Aims: Research suggests that specialised lighting design is essential to cater for the elderly users of a building because of reduced visual performance with increased age. This review aims to document what is known of the physical and psychological aspects of lighting and their role in promoting a healthy and safe environment for the elderly. Methods: A methodical review was carried out of published literature on the physical and psychological impacts of light on the elderly. Design standards and guides from professional organizations were evaluated to identify synergies and gaps between the evidence base and current practice. Results: Lighting has been identified as a significant environmental attribute responsible for promoting physical and mental health of the elderly. The evidence related to visual performance was found to be robust. However, guides and standards appeared to have focused mostly on illumination requirements for specific tasks and have lacked detailed guidelines on vertical lighting and luminance design. This review has identified a growing body of evidence on the therapeutic benefits of lighting and its use in treating psychological disorders among the elderly. The experiments using light as a therapy have improved our understanding of the underlying principles, but the integration of therapeutic aspects of lighting in design practice and guidelines is lacking. Conclusions: While design guidelines discuss the physical needs of lighting for the elderly fairly well, they lack incorporation of photobiological impacts. Despite positive outcomes from research, the implementation of therapeutic aspects of lighting in buildings is still debatable due to insufficient relevant investigations and robustness of their findings. Collaborations between designers and physicians can contribute in delivering customised lighting solutions by considering disease types and needs. Further investigation needs to be carried out for translating therapeutic benefits to photometric units to implement them in building lighting design

Implementasi sertifikasi amil zakat di YDSF Malang

INDONESIA: Zakat salah satu dari rukun sebagai salah satu instrumen pengentas kemiskinan. Indonesia memiliki potensi yang sangat tinggi dalam menghimpun dana zakat, dikarekan mayoritas penduduk Indonesia adalah beragama Islam. Untuk meningkatkan dan juga menjamin mutu pengelolaan zakat serta amil zakat yang profesional, serta perlunya untuk mengatur mengenai standarisasi dalam pengelolaan di bidang zakat, maka BAZNAS mengeluarkan Peraturan Nomor 2 Tahun 2018 tentang Sertifikasi Amil Zakat. YDSF Malang merupakan salah satu organisasi pengelola zakat di kota Malang. Penelitian ini bertujuaN untuk mengkaji lebih dalam lagi terhadap pengimplementasian Sertifikasi Amil Zakat di YDSF Malang serta apa saja faktor penghambat dan pendukung pengimplementasian peraturan tersebut. Penelitian yang digunakan oleh peneliti adalah penelitian lapangan dengan metode kualitatif deskriptif. Adapun sumber data primer ini berasal dari 3 amil zakat YDSF Malang yang sudah bersertifikasi amil zakat. Pengolahan data melaui tahap-tahap : pemeriksaan data, klasifikasi, verifikasi, analisis, dan kesimpulan. Dalam penelitian ini menghasilkan kesimpulan bahwa : (1.) Jadi di YDSF Malang telah menerapkan sertifikasi amil zakat di YDSF Malang akan tetapi sertifikasi itu belum sepenuhnya diterapkan kepada semua amilnya. Hal ini dikarenakan adanya standar yang ditetapkan oleh lembaga untuk bisa mengirim amilnya dalam mengikuti sertifikasi amil zakat. Ada beberapa persyaratan atau SOP baik dari pihak lembaga YDSF Malang ataupun dari BAZNAS yang harus dipenuhi oleh para amil untuk mereka bisa mengikuti ujian sertifikasi amil itu sendiri. (2.) Adapun faktor penghambat untuk bisa menerapkan peraturan tersebut dari YDSF Malang adalah sumberdaya manusia, terkait kesiapan atau kemampuan amil itu sendiri. Adapun yang menjadi faktor pendukung untuk bisa menerapkan peraturan ini adalah adanya komunikasi; disposisi; dan struktur birokrasi. ENGLISH: Zakat which is one of the pillars as an instrument of poverty alleviation. Indonesia has a very high potential in collecting zakat funds, because the majority of Indonesia's population is Muslim. The one who manages zakat is called amil. To improve and ensure the quality of zakat management and professional zakat management, as well as the need to regulate standardization in zakat management, BAZNAS issued Regulation Number 2 of 2018 concerning Certification of Amil Zakat. YDSF Malang is one of the zakat management organizations in the city of Malang. This study aims to examine more deeply the implementation of the Indonesian Amil Zakat Agency Regulation Number 2 of 2018 concerning Amil Zakat Certification at YDSF Malang and what are the inhibiting and supporting factors for the implementation of the regulation. The research used by researchers is field research with descriptive qualitative methods. As for the primary data source, it comes from 3 amil zakat in YDSF Malang who have received amil zakat certification. Data processing through the stages: data checking, classification, verification, analysis, and conclusions. In this study, This research concludes that: (1.) So YDSF Malang has implemented zakat amil certification at YDSF Malang but the certification has not been fully applied to all amil. This is because there are standards set by the institution to be able to send their amil in participating in zakat amil certification. There are several requirements or SOPs from either the YDSF Malang institution or from BAZNAS that must be fulfilled by the amil so that they can take the amil certification exam itself. (2.) The inhibiting factor for implementing the regulation from YDSF Malang is human resources, related to the readiness or ability of the amil itself. As for the supporting factors to be able to apply this regulation is the existence of communication; disposition; and bureaucratic structures. ARABIC: الزكاة ركن من أركان التخفيف من حدة الفقر. تتمتع إندونيسيا بإمكانيات عالية جدًا في تحصيل أموال الزكاة ، لأن غالبية سكان إندونيسيا مسلمون. لتحسين وضمان جودة إدارة الزكاة والإدارة المهنية للزكاة ، وكذلك الحاجة إلى تنظيم التوحيد القياسي في إدارة الزكاة ، أصدرت بازناس اللائحة رقم 2 لعام 2018 بشأن اعتماد عامل الزكاة. YDSF Malang هي إحدى منظمات إدارة الزكاة في مدينة مالانج. تهدف هذه الدراسة إلى إجراء فحص أعمق لتطبيق شهادة زكاة العامل في YDSF Malang وما هي العوامل المثبطة والداعمة لتنفيذ اللائحة. استخدمت الباحثة بهذا البحث منهاجا وصفيا كيفيا. أمّا مصدر الأساسي بهذا البحث هو من ثلاثة عوامل YDSF مالانج الذين تم تصديقها من عامل الزكاة. طريق تحليل البيانات المستخدمة بهذا البحث هي تفطيش البيانات، تصنيف البيانات، التحقق، تحليل البيانات، و الإستنباط. يخلص هذا البحث إلى ما يلي: 1.( لقد نفذت YDSF Malang شهادة زكاة الأميل في YDSF Malang ولكن لم يتم تطبيق الشهادة بالكامل على جميع الأميل. هذا بسبب وجود معايير وضعتها المؤسسة لتتمكن من إرسال الأميل الخاص بهم في المشاركة في شهادة زكاة الأميل. هناك العديد من المتطلبات أو إجراءات التشغيل الموحدة من مؤسسة YDSF Malang أو من BAZNAS والتي يجب أن يفي بها الأميل حتى يتمكنوا من اجتياز امتحان شهادة الأميل نفسه. 2.( العامل المثبط للقدرة على تطبيق اللوائح من YDSF Malang هو الموارد البشرية ، المتعلقة باستعداد أو قدرة الأميل نفسه. أما بالنسبة للعوامل الداعمة للقدرة على تطبيق هذه اللائحة فهي وجود الاتصال ؛ تغير؛ والهياكل البيروقراطية

Determination of isotope ratio in the divertor of JET-ILW by high-resolution H alpha spectroscopy: H-D experiment and implications for D-T experiment

The data of the H alpha high-resolution spectroscopy, collected on the multiple lines of sight, which cover the entire divertor space in poloidal cross-section, during the recent hydrogen-deuterium experiments in JET-ILW (ITER-like wall), are processed. A strong spatial inhomogeneity of the hydrogen concentration, H/(H + D), in divertor is found in many pulses. Namely, the H/(H + D) ratio may be lower in the inner divertor than that in the outer divertor by the values of 0.15-0.35, depending on the conditions of gas puffing and plasma heating. This effect suggests the necessity of spatially-resolved measurements of isotope ratio in the divertor in the upcoming deuterium-tritium experiments. Also, separation of the overlapped T alpha and D alpha spectral lines is shown to be a challenging task especially when the local Doppler-broadened (Gaussian) line shapes are noticeably distorted by the net inward flux of fast non-Maxwellian neutral atoms. We use the respective, formerly developed model of an asymmetric spectral line shape, while analysing the data of the first deuterium-tritium experiment in JET-C (carbon wall), and test the model via comparing the isotope ratio results with another diagnostic's measurements. This model is shown to increase the accuracy of tritium concentration measurements in the divertor
