Group Dynamics Management and Performance of Road Infrastructure Projects

Performance of road infrastructure projects is crucial for the growth and development of the economy. However, firms especially the local firms experience problems in enhancing team work and cohesion to enable them complete projects within the budgeted cost, time schedule and attaining the desired quality. Despite the crucial role played by project group dynamics management in determining the performance of road infrastructure projects, little attention has been paid to this key factor. This paper sought to establish the effects of group dynamics management on performance of road infrastructure projects. The study was carried out in the Lake Basin Region, Kenya that had a total of 41 road infrastructure projects undertaken by local firms. The study concluded that group dynamics management had a significant effect on performance of road infrastructure projects undertaken by local firms.
Fables of Abundance: A Cultural History of Advertising in America@@@Marketing Modernism in Fin-de-Siecle Europe@@@Privacy and Publicity: Modern Architecture as Mass Media

Through a series of close readings of two major figures of the modern movement, Adolf Loos and Le Corbusier, Beatriz Colomina argues that architecture only becomes modern in its engagement with the mass media, and that in so doing it radically displaces the traditional sense of space and subjectivity. "Privacy and Publicity" questions certain ideological assumptions underlying the received view of modern architecture and reconsiders the methodology of architectural criticism itself. Where conventional criticism portrays modern architecture as a high artistic practice in opposition to mass culture, Columina sees the emerging systems of communication that have come to define 20th-century culture - the mass media - as the true site within which modern architecture was produced. She considers architectural discourse as the intersection of a number of systems of representation such as drawings, models, photographs, books, films and advertisements. This does not mean abandoning the architectural object, the building, but rather looking at it in a different way. The building is understood here in the same way as all the media that frame it, as a mechanism of representation in its own right. With modernity, the site of architectural production literally moved from the street into photographs, films, publications and exhibitions - a displacement that presupposes a new sense of space, one defined by images rather than walls. This age of publicity corresponds to a transformation in the status of the private, Colomina argues; modernity is actually the publicity of the private. Modern architecture renegotiates the traditional relationship between public and private in a way that profoundly alters the experience of space. Colomina tracks this shift through the modern incarnations of the archive, the city fashion, war, sexuality, advertising, the window, and the museum, finally concentrating on the domestic interior that constructs the modern subject it appears merely to house.
RELATIONSHIPS BETWEEN HAND AND FINGER MUSCLE STRENGTH AND TAPPING ABILITY AMONG WORKERS DURING USING GRINDERS

Analyses of psychomotor changes before and during grinding work of thirty female workers performing a grinding operation with another thirty female office workers as the control group. Hand muscle strength was measured by assessing hand grip strength (HGS) and pinch strength (PS) while hand dexterity was measured by the maximum tapping ability in 10 seconds (MTA). The participants were asked to perform the tests at (1) initial time at 08.00 a.m., (2) before morning rest break at 10.00 a.m., (3) after morning rest break at 10.10 a.m., (4) before lunch at 12.00 a.m., (5) after lunch at 13.00 p.m. , (6) before afternoon rest break at 15.00 p.m. , (7) after afternoon rest break at 15.10 p.m. and (8) end of work at 17.00 p.m. In contrast, the control office worker group was measured only at before work (08.00 a.m.). The result showed that the HGS, PS and MTA of the dominant hand were generally stronger than those of the non-dominant hand (p-value <0.05). Several pairs of raw data of the above parameters were computed by SPSS Inc. (2001 program) to find the significant level (p) and correlation coefficients (r). It was found that the MTA was significantly correlated with PS and HGS (r = 0.249 and 0.308, p-value <0.001, respectively). PS and HGS were significantly correlated (r = 0.708, p-value < 0.001). This may show that all tests confirmed the changes of hand strength and dexterity after prolonged grinder using. The result shows that after the workers were exposed to vibration from the grinding process, they were affected by decreased hand muscle strength and decreased hand maximal tapping ability with relatively linear proportion.

Mechanistic–Empirical Analysis of Pavement Performance Considering Dynamic Axle Load Spectra Due to Longitudinal Unevenness

Pavement distresses are induced by mechanistic responses in pavement structure subjected to dynamic loads of moving vehicles. Pavement surface evenness deteriorates as pavement distresses propagate, which results in dynamic axle loads and faster pavement deterioration. It is vital to consider the dynamic axle load spectra to predict pavement deterioration using traffic-monitoring data. This study aimed to evaluate the effect of dynamic loads and overweight traffic on asphalt pavement overlay performance using mechanistic–empirical (M–E) pavement analysis. The relationship between dynamic load coefficients (DLCs), axle loads, and international roughness index (IRI) was obtained for accurate quantification of dynamic axle loads. Then the dynamic axle load spectra were derived by shifting the static axle load spectra in weigh-in-motion (WIM) data, given the DLC value. AASHTOWare Pavement ME software was used to analyze pavement performance with static and dynamic axle load spectra, and the impact of overweight traffic on asphalt pavement overlay performance. The impact of dynamic loads on reflective fatigue cracking was distinguished at an early stage of the service period and eliminated after the 10-year analysis period, when the propagation of reflective cracking reached a specific level. On the other hand, the consideration of dynamic axle loads increased the impact of overweight truck traffic on pavement distresses, and pavement structures of major highways tend to be more sensitive to overweight traffic because of greater DLC excitement at higher operational speeds.
Analyzing Impact of Types of UAV-Derived Images on the Object-Based Classification of Land Cover in an Urban Area

The development of UAV sensors has made it possible to obtain a diverse array of spectral images in a single flight. In this study, high-resolution UAV-derived images of urban areas were employed to create land cover maps, including car-road, sidewalk, and street vegetation. A total of nine orthoimages were produced, and the variables effective in producing UAV-based land cover maps were identified. Based on analyses of the object-based images, 126 variables were derived by computing 14 statistical values for each image. The random forest (RF) classifier was used to evaluate the priority of the 126 variables. This was followed by optimizing the RF through variable reduction and by comparing the initial and optimized RF, the utility of the high-priority variable was evaluated. Computing variable importance, the most influential variables were evaluated in the order of normalized digital surface model (nDSM), normalized difference vegetation index (NDVI), land surface temperature (LST), soil adjusted vegetation index (SAVI), blue, green, red, rededge. Finally, no significant changes between initial and optimized RF in the classification were observed from a series of analyses even though the reduced variables number was applied for the classification.
Comparison of Interactive Teaching in Online and Offline Platforms among Dental Undergraduates

In recent years, the educational system has focused more on the holistic development of an individual. Modern technology has changed the educational environment to provide students with better academic opportunities. Along with the education system, teaching techniques and learning tools have also changed with digital evolution. This research was undertaken to assess the academic performance of interactive teaching methods in offline and online platforms in Periodontics among BDS undergraduates at a dental college in India. This prospective study was conducted among 49 students: Group I (n = 24, online class through Zoom) and Group II (n = 25, offline classes). The subject was divided into three modules and was covered in one week. The topics covered, teaching methods, lectures, and activities were similar for both groups. A formative assessment mark was obtained from written tests during the module, whereas the summative assessment mark was recorded from exams conducted towards the end of the module. In the results, a statistically significant difference was not observed in terms of formative assessment between Group I (77.88 ± 12.89) and Group II (77.80 ± 16.09) (p = 0.98). In addition, a statistically significant difference was not observed in terms of summative assessment between Group I (80.54 ± 8.39) and Group II (80.28 ± 11.57) (p = 0.93). Overall, this study suggests that interactive teaching methods in both offline and online platforms in Periodontics showed equivalent performance by the undergraduate dental students.
Are GARCH and DCC Values of 10 Cryptocurrencies Affected by COVID-19?

This paper examines the dynamic conditional correlations among 10 cryptocurrencies and the possibility of hedging investment strategies among multiple cryptocurrencies over the period affected by COVID-19 from 2017 to 2022. After studying the relationship between Bitcoin, Ethereum, and the other eight cryptocurrencies, four main results were obtained in this paper: first, from the pre-COVID-19 period to the COVID-19 period, almost all of the cryptocurrencies’ return growth rates increased, and COVID-19 had a positive effect on the returns of cryptocurrencies. Second, all of the cryptocurrencies’ return indices had features of volatility clustering and memory persistence in the long run; from pre-COVID-19 to COVID-19, these cryptocurrencies’ GARCH values decreased, but the correlations among the varying GARCH values increased. Third, the varying correlations between the return indices of Bitcoin, Ethereum, and the other cryptocurrencies were very strong; from pre-COVID-19 to COVID-19, the average dynamic correlations between Bitcoin and the others increased. Fourth, Tether can be used as a hedge cryptocurrency against the other cryptocurrencies as COVID-19 enhanced its hedging feature.
THE EFFECT OF PROGRESSIVE MUSCLE RELAXATION TO MENTAL HEALTH ON ADOLESCENT

Background: During the covid-19 pandemic, there are changes in living habits that must be faced by everyone, including teenagers. Adolescents in orphanages in adjustment experience stress, depression and sleep disturbances that can affect the quality of life. For this reason, progressive muscle relaxation efforts can be used as a way to improve adolescent mental health.Methods: This type of research is an analitic observational. This research was conducted at the Marhdatillah Sukoharjo Orphanage, Central Java. The subjects in this study were 42 people living in the Mardhatillah orphanage which divided into control group (27 people) and intervention group (15 people). In both the control group and the intervention group, mental health assessments were carried out twice. In the intervention group, prior to the second mental health assessment, a progressive muscle relaxation intervention was performed. Data was collected using the Strengths and Difficulties Questionnaire (SDQ) and intervention. Analyzed by independent t-test with SPSS 21.Results: The results of the independent t test were significant (p=0.042). The control group consisted of 27 subjects with a mean post-test SDQ score of 23.8 (abnormal) and post-test 13.22 (borderline). The intervention group consisted of 15 subjects with a mean SDQ score of 22.2 pre-test (abnormal) and 9.40 post-test (normal). Conclusion: Progressive muscle relaxation can improve mental health in adolescents who live in the Mardhatillah orphanage, Sukoharjo, Central Java.
Cell-Assisted Lipotransfer in Breast Augmentation Surgery: Clinical Outcomes and Considerations for Future Research

Autologous fat transfer is a widely used surgical technique, chosen by numerous plastic surgeons for breast augmentation surgery. This technique is based on three steps: 1. harvesting of the lipoaspirate from the patient, 2. centrifugation and removal of the top, oily, layer, and 3. implantation in the patient’s breast(s). It has been associated with various complications, including post-surgical fat resorption, as measured quantitatively with MRI, CT, and other 3D-quantification systems. Adipose-derived stem cells have been explored as a means of addressing fat resorption. They can be separated from the lipoaspirate following centrifugation, and enzymatically purified from unwanted debris, with collagenase, forming the stromal vascular fraction. The stromal vascular fraction is then recombined with the graft volume prior to implantation. This novel technique, referred to as “cell-assisted lipotransfer”, has shown promising results in terms of reducing fat resorption. These results are due to the pro-angiogenic and pro-adipogenic ability of the stem cells, which allow the graft to address the conditions of ischemia more effectively than autologous fat transfer. The aim of this review is to explore the ways in which cell-assisted lipotransfer is different from the autologous fat transfer, as well as how and why adipose-derived stem cells may contribute towards limiting fat resorption. The immunological background of these cells is discussed in detail, while grounds for further development are discussed, by means of the administration of external growth factors, which could, potentially, maximize outcomes, while limiting complications.
The Complex Metabolomics Crosstalk Triggered by Four Molecular Elicitors in Tomato

The elicitation of plant secondary metabolism may offer interesting opportunities in the framework of sustainable approaches in plant science and in terms of their ability to prime resistance to biotic and abiotic stressors. The broad metabolic reprogramming triggered by different molecular elicitors, namely salicylate (SA), polyamines (PAs), and chitosan, was comprehensively investigated using a metabolomics approach and the tomato (Solanum lycopersicum L.) as the model crop. Six different treatments were compared: a negative control (no treatments), a second negative control treated with 1 M acetic acid (the reference for chitosan, since chitosan was solubilized in acetic acid), and four molecular elicitors, 1 mM 2,1,3-benzothiadiazole (BTH, a positive control), 10 mg/mL chitosan, 0.01 mM SA, and a 0.1 mM PA (putrescine, spermidine, and spermine). All treatments determined a slight increase in biomass, in particular following PA treatment. A broad reprogramming of secondary metabolism could be observed, including membrane lipid remodeling, phenylpropanoid antioxidants, and phytohormone crosstalk. Overall, our results suggest that PAs, SA, and BTH shared a systemic acquired resistance (SAR)-related response, whereas chitosan induced a more distinct induced systemic resistance (ISR)-like jasmonate-related response. These results pave the way towards the possible use of elicitors as a sustainable tool in plant science and agriculture by increasing crop resilience to biotic and abiotic stressors without detrimental effects on plant biomass.
Does improvement in education level reduce ecological footprint? A non-linear analysis considering population structure and income

The purpose of this paper is to investigate the non-linear effect of education level on ecological footprint considering changes in population structure and per capita income. The results show an inhibitory effect for the level of education on increases in ecological footprint. In high-income countries, this inhibitory effect is non-linear. The inhibitory effect of education level on ecological footprint increases with increases in education level. In addition, population structure also has an inhibitory effect on the increase in ecological footprint. In both high-income and low-income countries, the inhibitory effect of population structure on the ecological footprint decreases when the population structure exceeds the threshold. However, there is a promotional effect of GDP per capita on the increase in ecological footprint. And the threshold regression results show that this promotional effect is linear in all income groups. Finally, this study suggests that countries should develop environmental sustainability policies according to the threshold range in which their education level, population structure, and per capita income are located.
Optimizing Tomato (Solanum lycopersicum L.) Growth With Different Combinations of Organo-Mineral Fertilizers

With the aim of promoting sustainable agriculture that respects the environment and human health, a study was carried out to evaluate the impact of organic and mineral fertilizers on tomato plant cultivation. The study was carried out at the Research Station of Farako-Bâ in Burkina Faso. A complete randomized block of Fisher design with four replications was used to carry out the experiment. The treatments were as follows: T0: control (compost 15 t/ha); T1: compost (15 t/ha) + biosol (160 kg/ha) + urea (35 kg/ha) + NPK (87.5 kg/ha) + KCl (52.5 kg/ha); T2: compost (15 t/ha) + neem seed cake (10 t/ha) + urea (100 kg/ha) + NPK (250 kg/ha) + KCl (150 kg/ha); T3: compost (15 t/ha) + biochar (10 t/ha) + urea (100 kg/ha) + NPK (250 kg/ha) + KCl (150 kg/ha). The data collected were collar diameter, height of plants, number of fruits, fruit diameter, and tomato fruit yield. The results showed that the combination organo-mineral fertilizers had a significant effect on tomato plant productivity. Application of neem seed cake and mineral fertilizers was the most efficient treatment with a yield increase of 53% and 40% in 2019, respectively. In 2020, the yield increase was 32 and 85% for biochar and biosol, respectively. Incorporation of organo-mineral fertilizers has improved soil organic and nutrient status, which ultimately promotes crop growth of tomato plant. Neem cake can be effectively used to increase tomato plant productivity and farmer's income and also maintain soil fertility.
Use of sulfate-reducing bacteria and different organic fertilizer for bioremediation of ex-nickel mining soils

The microbiological activity associated with exmining soil remediation can be considered useful to accelerate the contaminant degradation. The use of sulfate-reducing bacteria (SRB) and organic matter exhibits potential in improving ex-nickel mining soil quality. The purpose of this study was to examine the ability of SRB in several organic fertilizers to reduce sulfate and nickel ions, and to increase pH of soil from nickel in mining areas. This study used the bacteria collection of the Soil Laboratory of the Faculty of Agriculture, Universitas Muslim Indonesia. Those were previously isolated from two cultivating pond of milkfish in the Kuri area of Maros Regency, South Sulawesi, Indonesia. The soil samples were collected from ex-mining areas of the Vale Indonesia Enterprise in Soroako, South Sulawesi, Indonesia. Those were mixed with organic fertilizers, generated from sugarcane sludge, manure, and Quickstick (Gliricidia sepium) leaves, each with 50 and 100 g doses. The 5 kg soil samples were put into a pot and mixed evenly with organic fertil- izers. A general linear model (GLM) repeated measures analysis of variance (ANOVA) was adopted to analyze the data. The results of this study indicate that the application of SRB and fertilizer was effective in reducing concentration of sulfate and nickel. Among the three types of organic fertilizers, manure was effective in reducing sulfate and nickel concentrations, while Quickstick fertilizer was the more effective in stabilizing pH level. Fertilizer doses exhibited a significant effect on decreasing sulfate and nickel concentrations, but it exhibited no significant effect on stabilizing pH levels. At 10 days after treatment (DAT), the sulfate concentration decreased from 2,530 ppm to 1,443 ppm in treatment of SRB and manure with dose of 50 g and 1,363 ppm with that of 100 g. At the end of the observation (30 DAT), those were decreased to 1,217 ppm in treatment of SRB and manure with doses of 50 g and 1,167 ppm with that of 100 g. Among the three types of organic fertilizers used, Quickstick demonstrates the more effective reduction rate. At 10 DAT, pH increased in SRB treatment by 7.06 at a concentration of 50 g and 7.01 at a concentration of 50 g. At the end of the observation (30 DAT), the pH became 6.67 at a concentration of 50 g and 6.82 at a concentration of 50 g. The nickel concentration decreased from an origin concentration to 1,950 ppm in treatment of SRB and manure with doses of 50 g and 1,690 ppm with that of 100 g. Thus, the application of manure fertilizer and the addition of SRB is recommended for bioremediation of sulfate and nickel from ex-mining soil.
Closed-loop waveform control of boost inverter

The input current of single-phase inverter typically has an AC ripple component at twice the output frequency, which causes a reduction in both the operating lifetime of its DC source and the efficiency of the system. In this paper, the closed-loop performance of a proposed waveform control method to eliminate such a ripple current in boost inverter is investigated. The small-signal stability and the dynamic characteristic of the inverter system for input voltage or wide range load variations under the closed-loop waveform control method are studied. It is validated that with the closed-loop waveform control, not only was stability achieved, the reference voltage of the boost inverter capacitors can be instantaneously adjusted to match the new load, thereby achieving improved ripple mitigation for a wide load range. Furthermore, with the control and feedback mechanism, there is minimal level of ripple component at the DC bus during steady state, and the transient response is rapid with negligible effect on the output voltage. Analysis, simulation and experimental results are presented to support the investigation.
