Published: May 2022

Rapid and accurate evaluation of oxygen reduction reaction (ORR) kinetics for massive potential electrocatalysts is critical for developing sustainable energy conversion devices. In principle, both the consumption rate of O2 and production rate of reactive oxygen radicals (ROS) intermediates can be used to establish the ORR rate equation. Notably, owing to the grand challenge in quantitative in-situ detection of trace-amount of ROS, most previous ORR kinetics studies rely on direct electrochemical examination of O2 consumption, but which is inevitably hampered by the slow mass transfer of O2 in electrolytes. Here we report a time resolved electrochemiluminescence (Tr-ECL) strategy to establish ORR rate equation via ultra-sensitive detection of ROS intermediates. As ROS were generated at electrocatalysts surfaces in the diffusion layer, it intrinsically circumvented the limit of mass transfer of O2 in electrolytes during ORR. As a result, ORR electron transfer numbers, rate constants, and ROS concentration-potential correlations that is closely related to the stability of electrocatalysts were successfully obtained by principal component analysis of ECL intensities and finite elemental analysis of time-resolved ECL decay curves. It provides a rapidly, precisely, and facile way to understand ORR mechanism and would greatly pave development of electrocatalysts with appropriate catalytic activity, selectivity and stability.

Authors:   KOREA CPTED ASSOCIATION, Park So-Yeon , Lee Kyung-Hoon , Tadić Miroslav , Kang Seok-Jin
Published: May 2022

The purpose of this study is to determine whether a house's intrusion route is a more useful analysis unit for explaining residential burglars' choice than the house as a whole. Also, we investigated whether a predictive model derived separately from the selected intrusion route better describes burglary decisions than a model derived from the entire response at once. Kruskal-Wallis tests were used to assess whether the participants' evaluations were influenced by the general state of the house or that of the chosen intrusion route. Additionally, two regression studies were undertaken to investigate the effect of the intrusion route chosen on the derivation of regression models. The results indicated that the targeted house is evaluated primarily on the basis of environmental factors associated with the selected intrusion route, rather than on the basis of all environmental elements throughout the house. This result infers that the intrusion route should be treated as an analysis unit to obtain more accurate results for environmental factors affecting burglar's target selection.
An Analysis of the Effectiveness of CPTED in Traditional Markets through the Pre- and Post-Project Survey
Authors:   KOREA CPTED ASSOCIATION, Kang Seok-jin , Hong Seong-jin , Lee Su-jin , Kim Go-won
Published: May 2022

This study was conducted to explore implications for CPTED application in the future and to analyze crime prevention effect through analysis of the current status and questionnaire data of CPTED projects in traditional markets The spatial scope of this study was a traditional market located in the original downtown of four cities (Incheon, Paju, Cheongju, and Suncheon), and the content of this study was survey data analysis conducted before and after the CPTED project.
As a result of analyzing the current satisfaction and necessity of improvement of the crime prevention environment before the project, items with low satisfaction and high necessity for improvement were lighting brightness, legibility of facilities (CCTV, emergency bells, information signs), and maintenance of garbage and neglected environments.
The results of analyzing the perception of crime safety are as follows.: 1) Before the project, the percentage of people who thought a crime was serious was 28.0% and the percentage of people who thought safety about crime was 26.0% in four markets. However, after the project, the percentage of serious consideration of crime decreased significantly to 5.0%, and the percentage of safe consideration rose to 70.1% on average.
2) The effect of reducing the crime problem was also confirmed by comparing the fear of types of crimes (night crimes, night crimes, interpersonal crimes, property crimes, and location crimes) conducted before and after the project.
3) The cause of fear of crime differed before and after the project. The expansion of crime prevention facilities (safe lighting, CCTV, emergency bell installation, and legibility reinforcement) was mainly carried out in four markets. Therefore, the cause of fear of crime after the project was found to be related to structural problems such as 'not seen around, few people, and little use', or changes in the use of spaces and facilities. This can be said to be a characteristic of the CPTED project conducted in the short term within a limited range (such as budget).
In order to create a crime prevention environment in the traditional market in the future, the following items are considered necessary.
In the short term, the CPTED principle that increases the legibility of crime prevention facilities installed around external spaces can be helpful. This inference is also linked to the highest satisfaction of survey respondents and the highest expected effect on crime prevention for enhancing the legibility of CCTVs, emergency bells, and information signs installed in each market.
However, in order for these contents to continue the crime prevention effect, maintenance must be accompanied over time. Therefore, from a mid- to long-term perspective, it is thought that the CPTED principle that increases the internal and external utilization of the space, such as the use of empty stores or the improvement of blind spots, should be accompanied.

The article is devoted to the improvement of the management decision-making methods based on a qualitative data analysis. It provides a justification for the need to introduce a quantitative indicator that can be used to measure the region of the time series concentration (pseudoattractor), i.e. the set of its close values, and describes the procedure for its construction. Classical statistical time series meters (the variation range and the indicator of variation) have a number of disadvantages that do not allow them to be used in their traditional capacity for the analysis of relational time series – series obtainedas a result of dividing the values of one time series by the corresponding simultaneous values of another time series. The constructed meter is dimensionless, normalized, and invariant with respect to the division procedure. In addition, it is insensitive to changes in the length of the series if the values being added or removed are enclosed within the boundaries defined by local extremes (minimum and maximum). The constructed quantitative indicator is added to the method of delayed coordinates, which is a method of qualitative analysis of the behavior of time series. The combination of such tools is convenient for fast data analysis and does not require special mathematical training, which makes that approach accessible to managers.

Silica and Connective Tissue Disorders: The Important Role of the Dermatologist
Authors: Yates Deborah H , Miles Susan E
Published: May 2022

Dermatological manifestations of connective tissue diseases (CTDs) are common and frequently precede other symptoms. Thus, dermatologists may be the first clinicians to diagnose these disorders. Silica exposure is an acknowledged cause of several CTDs, but this is under-appreciated by clinicians, who may also be unaware of the wide range of jobs in which silica exposure can occur. The CTDs associated with silica exposure include systemic sclerosis (SSc), rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), anti-neutrophil cytoplasmic antibody (ANCA) positive vasculitis and overlap syndromes. Silica-related systemic sclerosis (Si-SSc) is associated with a specific antibody profile and more severe disease. Silicosis has re-emerged worldwide recently due to several new workplace exposures, including a new type of silicosis (artificial stone (AS) silicosis), which is associated with a particularly high rate of auto-antibody formation. Dangerous work practices are still occurring. This article summarises recent literature on the topic of the resurgence of silicosis and silica-induced CTDs and reminds dermatologists of the importance of taking a thorough occupational history in all patients. Early intervention in CTDs and reduction in dust exposure can reduce risk and improve prognosis. Treatment options are rapidly improving.

Nutrients are essential for the growth of plants and they also increase the yield. Among the major nutrients, nitrogen is the most important nutrient for crop growth. The current study aims to estimate chlorophyll content vis-a-vis nitrogen content using different techniques and attempts to establish comparative benefits among available techniques. Maize crop being highly known for fertilizer responsiveness was chosen to carry out experiments with different levels of nitrogenous fertilizers. A preliminary field survey was taken in the farmer's field in Coimbatore and Salem districts. Two field experiments and one pot culture experiment at different doses of nitrogen input were conducted in 2019, 2020, and 2021 in the Department of Nano science and Technology at Tamil Nadu Agricultural University. In this study conventional nitrogen was applied with various dosage viz.,0 kgha-1(T1), 50 kgha-1 (T2), 100 kgha-1 (T3), 150 kgha-1 (T4), 200 kgha-1 (T5), 250 kgha-1 (T6), 300 kgha-1 (T7). In the pot culture experiment, IFFCO Nano nitrogen was sprayed on the maize leaves with seven different doses which were control (no spray) (T1), conventional nitrogen (T2), 0.5X RDF(Recommended Dose of Fertilizer) (T3), 1.0X RDF (T4), 1.5X RDF (T5), 2.0X RDF (T6), 2.5X RDF (T7). The chlorophyll content in all the trials were estimated using Dimethyl sulfoxide(DMSO), a portable in-house developed nutrient meter, and Spectroradio meter method. Chlorophyll content was measured at two different growth stages of maize viz., 60 & 90 days after sowing. The total nitrogen was analysed using Kjeldahl method in the maize leaf. Among the treatments, with different doses of nitrogen levels, 300 kgha-1 RDN & 2.5X RDF (T7) recorded higher SPAD (Soil Plant Analysis Development) values, chlorophyll “a” and chlorophyll “b” content and total nitrogen content at 60 DAS (Days After Sowing) in all tested methods. Chlorophyll and total nitrogen content were significantly decreased in later days. In a stressed environment with no nitrogen (T1) applied condition the chlorophyll and nitrogen content showed significantly lower levels

Background: Iron deficiency anemia is common during pregnancy since the overall iron requirement is greater than non-pregnant women and is associated with adverse outcomes. Iron deficiency (ID) is a state of insufficient iron to maintain normal physiological functions of tissues and leads to anemia. Objectives: To assess factors associated with the utilization of Iron with Folic acid supplement Among Pregnant Women Attending Antenatal care at Government Health Facilities and Family Guidance Clinic in Hawassa City, South Ethiopia. Methods: Institutional-based cross-sectional study design was conducted among 412 health providers who are working at public health institutes in Hawassa city from March to April 2015. Pretested Self-administered questionnaires were used to collect the data. The data was entered into Epi-data and analysed by SPSS version 26.0. Bivariate and multivariate regression analysis was used to see the significant association between the outcome and independent variables. Odds ratios and 95% CI will be computed to measure the strength of the association, p - value of ˂ 0.05 will be considered a statistically significant. Results: A total of 412 pregnant women who came to attend ANC at least for the second time were interviewed in seven health facilities. Our study showed that 333 (81%, 95% CI: 77.2 - 84.8) pregnant women reported taking IFA supplements and high compliance was 37.7% (95% CI: 32.5 - 42.9). In multivariable analysis, side effects and low acceptance of the supplement were significantly associated with compliance to IFA supplementation (p < 0.05). Conclusion: There is a relatively better level of compliance towards IFA supplementation compared to other national data. Pregnant women should be counseled regarding how to manage the side effects of IFA supplements during ANC. Further research has to be done on the acceptability of the supplements.

Published: May 2022

Urea hydrolysis is widely used in agriculture, environment and other engineering fields, among which urease contained in beans can catalyze urea hydrolysis. The urea hydrolysis activity of legume plant leaching solution (LPLS) was investigated, including soybeans, black beans, mung beans, red beans as well as soybean hulls, soybean leaves, soybean stems and soybean pods. For the high urea hydrolysis activity and economic efficiency, soybean is most suitable for agricultural engineering and other fields than other beans and soybean-related parts extract. The urea hydrolysis activity increases with the concentration of LPLS, while decreases gradually with reaction time. When the heating temperature reaches 25, 35, 45, 55 and 65 ℃, the urea hydrolysis activity is steady and the enzyme activity is high. Enzyme activity decreases after 65 °C (i.e.75, 90 °C). Meanwhile, the soaking time of LPLS has a little effect on the urea hydrolysis activity compared with other factors. These results make a positive contribution to domestic production urease experimental basis.

Published: May 2022

The parameters of electromechanical converters functioning as part of working sets can change as a result of the influence externa factors, such as changes in the characteristics of the environment. Changes in parameters also occur due to parametric disturbances caused by changes in the physical characteristics of the elements electromechanical converters. In this regard, the development of methods and algorithms that provide analysis and control of the functioning electromechanical converters is an urgent task. The article discusses a digital algorithm for monitoring the functioning of an electromechanical DC converter, based on obtaining characteristics in a tabular-graphic form. These characteristics reflect the relationship between the vector of unstable parameters of the research object χ and the generalized integral criterion Q as a function of the discrepancy between the output coordinates of the electromechanical converter and its reference model. Discrete transfer functions of the reference model and sensitivity models are obtained for the monitored unstable parameters of the electromechanical converter. Based on the decomposition of discrete models, the corresponding direct programming schemes in the Frobenius form are constructed. The digital algorithms of the obtained models are represented by the difference equations of state and output. The structural scheme calculation of the generalized integral criterion Q and point dependencies χ (Q) is given. Discrete approximation was carried out using a bilinear transformation (Tustin's formula). A computer experiment for obtaining point χ-dependencies was carried out with varying degrees of accuracy, depending on the step of variations monitored parameters of the electromechanical converter within a given range of variation. The results obtained make it possible to assess the monitored unstable parameters of electromechanical DC converters with the required accuracy.

Published: May 2022

Capillary electrophoresis (CE) is an electromigration-based separation technique that emerged in the early 90s and has been evolving since then. Over recent decades, the association of CE with new technologies and detections strategies is enhancing its intrinsic mightiness. Today, CE is a part of the main high-throughput analytical platform used for medical-related applications, together with traditional gas chromatography, high-performance liquid chromatography, and fingerprinting spectroscopic methods. New strategies for assessing human disorders involve a thorough analysis of bodily fluids through said instrumentation. In this context, human urine is considered an excellent alternative, for being rich in information and easily collected with minimal inconvenience for the doners. Overall, since it is an ultrafiltrate of the human bloodstream, urine composition should be changed if any condition jeopardizes human homeostasis. Thus, monitoring the levels of biomarkers in urine by an advantageous technique such as CE can be an interesting choice for diagnostic and other clinical purposes. In this review, we will be commenting on the new tendencies and technologies applied to human urine analysis by CE over the last five years. We will be starting by commenting the applications onto target groups of molecules followed by addressing the CE feasibility for the determination of general chemical profiles through untargeted omics approaches, and finishing with the perspectives on the subject.

This research provides an investigation to measure the rate of corrosion of steel bars coated with organic corrosion inhibitor Lawsonia inermis (Henna) and inorganic corrosion inhibitor Sodium Nitrite (NaNO2) embedded in concrete. Presence of corrosion on the reinforcement bars reduces the bond strength between steel and concrete over a while and excessive corrosion on reinforcement bar can lead to loss of ductility, strength and in extreme cases collapse. Structures like marine structures, sewage pipes, which are prone to damage due to presence of excessive salts, acidic environment, the corrosion rate is accelerated when compared to normal structures, therefore there is need of protecting such type of structures. In previous researches, the corrosion inhibitors were added directly into the mix while preparing the concrete mix and inhibition efficiency was analysed. However, in this case, the corrosion inhibitors are applied to the reinforcing bars itself as the corrosion occurs on the bars and which has proven to be effective. In the present study, the reinforcement bars are coated with Henna paste and Sodium Nitrite paste as corrosion inhibitors. Inhibitors in the form of 2 layers, 4 layers and a combination were used. The beams specimens were cured for 58 days in saline environment. The difference in the corrosion potential is measured by half-cell potentiometer. Results suggested that the specimen with 4 layers of Henna coating had reduced the rate of corrosion by 46% when compared to original sample. Also, specimens with 2 coats of Henna and 4 coats of Henna and sodium nitrite showed better corrosion inhibition efficiency.

Visual comfort in office spaces improves not only productivity and wellbeing but also satisfaction and energy efficiency of the buildings. The objective of this research is to study the effect of one of the transporting daylighting systems (Anidolic Integrated Ceiling ‘AIC’) on the enhancement of the luminous interior environment and energy saving in office building through objective and subjective evaluations. The quantitative study was performed by measurement of the illuminance values in the physical model (1:4) under local luminous climate in two scenarios (with and without ‘AIC’) and by numerical simulation to calculate the daylight autonomy. The qualitative evaluations were achieved by using a field survey composed of four questions related to pleasantness, level of light and artificial lighting needs. Experimental study shows that the AIC offers high levels of illumination in quantitative terms result in moderate values of Daylight Factor (2% - 4%). Simulation results showed that more than 88% of energy consumption for electrical lighting can be saved. Subjective evaluation results indicate that in the test model (with AIC), 67% of participants felt more pleasant with the luminous environment, 74.19% considered that the level of light is sufficient and only 08 of 31 subjects need to use artificial lighting.

Slope failure or landslide is always ascribing to the slope sculptures in the hilly area. The trend of people building a structure on a hilly area has resulted in slope cutting works being carried out aggressively and, at the same time, has increased the risk of landslides. Most of the community lacks understanding regarding slope care and maintenance, which adds to the slope suffering. One of the factors contributing to slope failure is rainfall. The rainfall-runoff to the slope erodes the turfed and topsoil particles from the slope surface. When the slope surface is exposing to extreme weather, then the slope failure will occur. These failures pose a significant engineering hazard, necessitating urgent repair work and planning in many areas. All failures that occur will require expensive repairing costs. Therefore, this study is carried out to model the rainfall-induced slope failure occurrence at Kem Terendak, Melaka. This study utilises a simulation of slope stability analysis by limit equilibrium, Slope/W 2012 and finite element software for simulating groundwater flow in saturated steady-state situations, Seep/W 2012 in order to analyse the stability of the slope with the influence of climate. Through those analysis, one can understand the causes and mechanisms of the landslide. At the same time, the factors that influence the occurrence of failures can be identified and appropriate action can be taken to reduce or even eliminate the root cause of slope failures. In addition, effective and efficient slope repair methods can be proposed with optimal cost.

This study evaluated the suitable percentage of replacing natural coarse aggregate (crushed granite) with wasted Zinc Aluminum (Zincalume) generated from metal roofing fabrication industry to produce G35 grade eco–friendly concrete. Design mix for the wasted Zincalume substitution with crushed granite was prepared at 10%, 15% and 20% where the control mix specimen used as reference for mechanical strengths comparison. The mechanical strengths were observed with the increasing of curing age, but the strengths reduced with the increment of wasted Zincalume in the mixture. An amount of 10% of Zincalume substitution gave the optimum mechanical strength values. Acid – base reaction between cement and Zincalume coating in the concrete mixture, generated hydrogen gas, which reduced the compressive strength. The higher percentage of Zincalume in the concrete mixture, the weaker mechanical strengths were obtained. By recycling the steel waste, the eco – friendly concrete encourages to protect environment and enhance the economy growth.
