Implementation of Experience Design on Museum Interiors. Case Study: East Java Cultural Museum

This study examines the involvement of interior design with the museum purpose in terms of education and recreation. The purpose of this study is to provide effective solutions in museum interior design to attract attention, education, and recreation to visitors and form the basis for future research. This research creates a design that forms a spatial experience, with a focus on cultural museums. The method used in this study is a qualitative method with three stages of triangulation (interviews, observations, and documents). The case study in this study is the East Java Cultural Museum because the phenomenon that occurs is that traditional culture has begun to erode due to the times, especially in East Java, and the absence of research on the interior design of cultural museums. This study shows that there are five aspects in supporting the creation of a visitor's space experience in the museum, including the atmosphere of the room, lighting, collection displays, storylines, and interactive media. These five aspects are united in an "Experience Design".

Analisis Pencahayaan Ruangan Pada Ruang Kelas Di Universitas Singaperbangsa Karawang Menggunakan Dialux Evo 9.1

Room lighting is an important factor in the work environment to improve performance and is also a factor in occupational health and safety. Lighting that is not up to standard can cause eye fatigue, resulting in decreased worker performance. In educational institutions, the classroom is the room that is used most often compared to other rooms, so that the classroom needs adequate lighting to support the occurrence of teaching and learning activities in the room. In two classrooms at University of Singapperbangsa Karawang, indoor lighting analysis was carried out to determine the level of lighting. The purpose of this study is to determine whether the lighting level in the classroom is in accordance with the SNI 03-6575-2001 standard, which is 250 Lux. Based on the calculation of the number of lights, in class 1 it takes 8 lights and in class 2 it takes 14 lights. Calculations using Dialux Evo 9.1 in class 1 the lighting level during the day are 280 lux and at night is 187 Lux, while in class 2 the lighting level is 189 Lux during the day and 199 Lux at night. This shows that it is necessary to repair the lighting installation.

256 Spectrophotometric Properties of 31 Different Commercially Available Blue Blocking Glasses Under Electric Room Lighting

Introduction Blue blocking glasses are often marketed to promote relaxation, sleep, and circadian health by attenuating melatonin-suppressing light exposure. But these glasses represent a wide range of tint and other lens properties. Further, the utility of these glasses under ecologically valid indoor conditions (where light is typically generated from overhead broadspectrum fluorescent lamps) is still unclear, especially across various products. Methods A calibrated spectroradiometer (Ocean Insight), cosine corrector, optic fiber, and software package were used to measure the absolute irradiance (uW/cm^2/nm) emitted from overhead fluorescent lighting in a closeted dark room. Thirty-one commercially available blue blockers were individually placed between the cosine corrector and the luminaire, at a standardized distance and angle, where intensity was measured and analyzed. Each lens was evaluated individually relative to the light source under identical conditions. Then, lenses were collapsed by type into the following groups: red-tinted lenses (RTL), orange-tinted lenses (OTL), orange-tinted lenses with blue reflectivity (OBL), brown-tinted lenses (BTL), yellow-tinted lenses (YTL), and clear reflective blue lenses (RBL). Results There was significant variation in light-blocking across lens types (one-way ANOVA, p < 0.0001). On average, RTL and BTL restricted 59% of the visible light measured from 380-780nm. OTL blocked 47% of the light in this range, while OBL blocked 29%. Both YTL and RBL blocked 14% of the exposure. When narrowing the range of light to 440-530nm (the part of the spectrum most likely to produce a response from melanopsin-expressing retinal ganglion cells), we estimated the following performance: the RTL and OTL blocked close to 100% of the light, OBL blocked 98%, BTL blocked 80%, YTL blocked 33%, and RBL blocked 15%. These differences were statistically significant (one-way ANOVA, p < 0.0001). Individual lenses performed variably within groups, but these differences were small. Conclusion Focusing on the portion of the visible spectrum most likely to suppress melatonin secretion, RTL and OTL blocked exposure the best, followed by OBL, BTL, YTL, and (lastly) RBL.

The analysis of modern tendencies related to “Smart House” technologies is carried out in this article. The questions of programming languages of microcontrollers and microprocessors are considered. Software products that are used to create mobile applications for smartphones or tablets are presented. A computer system for remote control of room lighting is considered. The design and principle of its operation are shown schematically. A prototype of a computer system that has the following functions: 1) Control, on / off, lighting systems, depending on the needs of the owner of the premises. 2) Transfer of information about the level of illumination to the user, the owner of the premises. 3) Automatic switching on / off of electric, electroluminescent light sources, which are included in the room lighting control system. Photo of the prototype is shown. The principle of operation of the system control program based on the use of a photoresistor is presented. The Arduino microcontroller receives and processes information from the photoresistor, on the basis of which it automatically sends signals to the room lighting control system. The formulas for calculating the illumination using the results of the data obtained from the photoresistor of the prototype are given. The processed information, using wireless networks, goes to the interactive devices of the user, who can remotely check the value of illumination and, if necessary, control it.

Quinazoline Derivatives Designed as Efflux Pump Inhibitors: Molecular Modeling and Spectroscopic Studies

Multidrug resistance of bacteria is a worrying concern in the therapeutic field and an alternative method to combat it is designing new efflux pump inhibitors (EPIs). This article presents a molecular study of two quinazoline derivatives, labelled BG1189 and BG1190, proposed as EPIs. In silico approach investigates the pharmacodynamic and pharmacokinetic profile of BG1189 and BG1190 quinazolines. Molecular docking and predicted ADMET features suggest that BG1189 and BG1190 may represent attractive candidates as antimicrobial drugs. UV-Vis absorption spectroscopy was employed to study the time stability of quinazoline solutions in water or in dimethyl sulfoxide (DMSO), in constant environmental conditions, and to determine the influence of usual storage temperature, normal room lighting and laser radiation (photostability) on samples stability. The effects of irradiation on BG1189 and BG1190 molecules were also assessed through Fourier-transform infrared (FTIR) spectroscopy. FTIR spectra showed that laser radiation breaks some chemical bonds affecting the substituents and the quinazoline radical of the compounds.

Suppression of Circadian Timing and Its Impact on the Hippocampus

In this article, I describe the development of the disruptive phase shift (DPS) protocol and its utility for studying how circadian dysfunction impacts memory processing in the hippocampus. The suprachiasmatic nucleus (SCN) of the Siberian hamster is a labile circadian pacemaker that is easily rendered arrhythmic (ARR) by a simple manipulation of ambient lighting. The DPS protocol uses room lighting to administer a phase-advancing signal followed by a phase-delaying signal within one circadian cycle to suppress clock gene rhythms in the SCN. The main advantage of this model for inducing arrhythmia is that the DPS protocol is non-invasive; circadian rhythms are eliminated while leaving the animals neurologically and genetically intact. In the area of learning and memory, DPS arrhythmia produces much different results than arrhythmia by surgical ablation of the SCN. As I show, SCN ablation has little to no effect on memory. By contrast, DPS hamsters have an intact, but arrhythmic, SCN which produces severe deficits in memory tasks that are accompanied by fragmentation of electroencephalographic theta oscillations, increased synaptic inhibition in hippocampal circuits, and diminished responsiveness to cholinergic signaling in the dentate gyrus of the hippocampus. The studies reviewed here show that DPS hamsters are a promising model for translational studies of adult onset circadian dysfunction in humans.

Dual-Function Germicidal Recirculators for Air Disinfection and Erythema Irradiation or Room Lighting

This paper discusses different types of UV germicidal irradiators (UVIs), including (probably, for the first time) dual-function germicidal recirculators (producing germicidal irradiation together with erythema irradiation or illumination) and their characteristics. Methodological indications illustrated with examples, as well as some necessary information for public health officers in charge of epidemiological surveillance, are useful for relevant engineering calculations.
