Published: October 2020

Background:
Phytochemicals such as tannins, alkaloids, flavonoids, and peptides have
been found to have antimicrobial activity against a variety of bacterial strains.

Objective:
However, optimal extraction procedures for these phytochemicals and their efficacy
evaluation against certain pathogenic bacterial strains remain unclear.

Method:
Therefore, in this study, phytochemicals from Leucas aspera (L. aspera) and Dahlia pinnata
(D. pinnata) were extracted by hot and cold extraction methods using water and methanol as
solvents. In addition, antimicrobial activity of L. aspera and D. pinnata extracts against bacterial
strains such as the gram-negative Escherichia coli (E. coli) and the gram-positive Enterococcus faecalis
(E. faecalis) was performed by Minimal Inhibitory Concentration (MIC) and CFU quantification
assays.

Results:
The majority of the phytochemicals such as protein, carbohydrate, tannins, flavonoids,
phenols, and saponins were present in our extracts, but steroids were absent in the extract. Protein,
tannins, flavonoids, phenols, and saponins were present in both L. aspera and D. pinnata. The
yield of proteins was high (1.990 ± 0.091 mg/ml) in methanol extracts of L. aspera and low (0.199
mg/ml) in aqueous extracts. However, the yield of tannins was high (1.713 ± 0.079 mg/ml) in
methanol extracts of D. pinnata and low (0.528 ± 0.136 mg/ml) in aqueous extracts. The MIC of
D. pinnata extracts were found to be 200 mg/ml for both E. coli and E. faecalis. However, the L. aspera
extracts had an MIC of 100 mg/ml and 200 mg/ml on E. coli and E. faecalis, respectively.

Conclusion:
This article demonstrated the potential use of phytochemicals as novel antimicrobial
compounds against bacterial infections.

Published: October 2020

Ada kepercayaan umum bahwa minuman istonik berpotensi meningkatkan daya tahan dan aldosterone pada saat latihan dan pemulihan.Namun kepercayaan itu perlu dikaji ulang karena masih bisa untuk diperdebatkan dan lebih banyak lagi bukti empiris. Penelitian ini bertujuan untuk menguji minuma isotonik, air dan kontrol pada respon fisiologis, termasuk kapasitas daya tahan dan aldosterone pada saat latihan dan pemulihan pada saat cuaca panas. Dua belas atlet sepakbola prosseional dari Khon Kaen FC, Thailand yang terlibat dalam penelitian ini. Lari 3000 m, pemulihan 1 jam, dan waktu untuk uji kelelahan dilakukan dalam penelitian ini. Hasil penelitian menunjukkan tidak adanya respon fisiologis selama lari 3000 m dan pada saat pemulihan, denyut jantung lebih rendah dalam uji coba minuman isotonik dibandingkan dengan air dan control. Adanya perbedaan suhu oral, detak jantung, aldosteron, glukosa darah, dan natrium pada saat tes kapasitas daya tahan. Dapat dikatakan bahwa konsumsi minuman isotonik dapat meningkatkan kapasitas daya tahan dan mempertahankan aldosteron lebih efektif daripada dengan atau tanpa air yang mungkin disebabkan oleh peningkatan retensi cairan.

Background
Poor adherence to inhaled medication in asthma patients is of great concern. It is one of the main reasons for inadequate asthma control.

Objective
The goal of the research was to determine if motivational messages using short message service (SMS, or text) improved adherence to inhaled medication in patients with asthma.

Methods
A prospective multicenter randomized parallel-group clinical trial was conducted in 10 asthma clinics in Spain. Adherence was assessed with electronic monitors (Smartinhaler, Adherium Ltd) connected to inhalers. Patients in the SMS group received psychologist-developed motivational messages every 3 days for 6 months.

Results
There were 53 patients in the SMS group and 88 patients in the control group. After 6 months, mean electronic adherence was 70% (SD 17%) in the intervention group and 69% (SD 17%) in the control group (P=.82). Significant differences between the study groups in morning and evening adherence to inhaled therapy, asthma control, exhaled nitric oxide levels, or improvement of lung functions were not observed.

Conclusions
Motivational messages were not useful to improve adherence to inhaled asthma medication compared with usual care.
Engineering protection of buildings, structures and territoriesas a factor of innovative development of spatial planning
Authors: Zhuravlev Pavel A. , Marukyan Artur M. 
Published: October 2020

Introduction. A comfortable modern urban environment requires integrated spatial planning. An important constituent of integrated spatial planning is the engineering protection of buildings, structures and territories that ensures infrastructural development, natural positioning of construction facilities in ecosystems to preserve their natural relationships; protection of completed or constructed facilities from natural hazards, as well as protection of the population from the consequences of disruption into the ecosystem’s natural processes in the course of construction.
Materials and methods. Current legislation on urban planning, according to which the principle of effective use of territories is established, is considered. This principle is implemented through preparation and approval of spatial planning documentation that governs the positioning of capital construction facilities, the engineering infrastructure, as well as architectural and structural design, construction and reconstruction. It is noteworthy that the substantiation of a spatial planning project includes materials on activities performed to protect a territory from natural and man-made emergencies, as well as land development and engineering protection plans. The co-authors have analyzed statistical data, main reasons and factors affecting the integrated spatial development of territories that will accommodate construction projects and need to be taken into account.
Results. The co-authors provide a list of land development actions that ensure the best environment for the construction and operation of populated localities, siting and erection of buildings, street laying, construction of engineering networks and other elements of urban development. The co-authors compiled lists of engineering protection actions and appliances required to protect buildings and structures at the stages of spatial planning and design.
Conclusions. The co-authors have formulated principles (conditions) that govern administrative and engineering decision making in terms of engineering protection at the stages of spatial planning and project design. These principles substantiate the conclusion about the need for an integrated approach to engineering protection that encompasses preparation of an engineering protection pattern, including master, in-detail and specialized plans to ensure adjustable project solutions, design optimization, assessment of any prevented damages, substantiation of investments and preliminary calculation of consolidated approximate costs.

Authors: Laguta Viktor S. , Kalinichenko Sergei V. , Kuznecov Vladimir E. 
Published: October 2020

Introduction. Development of construction technologies and materials entails the use of larger and heavier aercrete blocks. Hence, it promotes construction industry automation through the use of robotic systems. Due to considerable costs of development, production and operation of robotic systems capable of substituting human workers at a construction site, thorough substantiation of their efficiency (or investment appeal) is required. It encompasses the calculation of total costs and the timing of its development and implementation, since no universal comprehensive solutions are available now.
Materials and methods. The co-authors have summarized practical design and engineering problems that may accompany the development of novel machinery and preparation of investment projects towards development of a construction robotic system (CRS) designated for aircrete block laying in the course of construction of buildings and structures. Two groups of experts were involved, Group One had civil engineers and Group Two had designers of robotic and mechatronic systems. Methods of expert evaluations and mathematical statistics were used; the co-authors also addressed specialized Internet websites and publications on design and engineering solutions.
Results. A list of criteria describing the performance of a robotic system was made with a focus on most important factors. The co-authors identified a set of parameters whose availability in a robotic system ensures ideal blockwork. The co-authors have developed a technical specification for a robotic system, identified its cost and developed an implementation schedule.
Conclusions. A formalized description of the future CRS, designated for construction purposes, is provided for the period of concept development. The co-authors also provided a reliable assessment of potential costs and schedules at the problem statement stage (a feasibility study), as it is important for the assessment of implementability of investment processes (a business plan) in terms of making a decision to initiate project implementation.

Authors: Liubarskaia Maria A. , Chekalin Vadim S. , Bachurinskaya Irina A. 
Published: October 2020

Introduction. New needs and opportunities boost demand for development of urban infrastructure in a contemporary society. The emergence of innovative technologies enables infrastructural elements to better meet the requirements of comfort, sustainability, and safety. Cities are getting “smarter”, as they constantly improve the economic, social and environmental efficiency of their utility, power supply, and transport systems. In the meantime, growing private, industrial and service demands for versatile resources set the trend for bigger environmental footprints in big cities. The mission of this research project is to substantiate the need for and to identify methods of reducing environmental footprints in the course of urban infrastructure management.
Materials and methods. The subject of this research project is the correlation between management functions and stages of the life cycle of urban infrastructure. Special focus is placed on the analysis of the influence produced by urban power grids, water supply and sewage networks and urban waste treatment on environmental footprints of big cities. A combination of positivistic and phenomenological philosophies is employed for this purpose; their influence manifests itself in the substantiation of findings, arising out of the opinions expressed by Russian and foreign experts, and statistical data.
Results. The findings represent sources of negative influence of infrastructural elements on the scale of environmental footprints and environmental safety levels, as well as suggestions concerning stages and actions contributing to minimization of environmental footprints of developing infrastructural systems with regard for the current stage in the lifecycle of an infrastructural facility.
Conclusions. A quantity index, demonstrating the environmental footprint of infrastructural facilities in operation, can be introduced as a summarized criterion for the socio-economic assessment of operation of infrastructural systems in urban economies.
“Intervenir en la realidad”: usos políticos del video indígena en Bolivia
Authors: Zamorano Villarreal Gabriela 
Published: October 2020

Este artículo discute cómo un grupo de comunicadores indígenas en Bolivia, a través del Plan Nacional Indígena Originario de Comunicación Audiovisual, utiliza el video como una manera de “intervenir en la realidad” política del país. A través de un análisis etnográfico, el artículo explica cómo el proceso de producción de los videos crea, con la participación de actores indígenas “no profesionales”, dirigentes, autoridades y comunicadores, un espacio común de debate y negociación en torno a realidades que no han sido visibles en la escena nacional con el fin de concebir futuros políticos distintos. El trabajo incluye una reflexión sobre: 1) La manera en que los videos retoman las vivencias personales y la memoria histórica de los comunicadores, actores y comunidades en el momento de desarrollar personajes e historias. 2) Los usos de las propiedades tecnológicas del video. Concluye con una reflexión sobre la evocación de vivencias en los discursos indígenas contemporáneos.
Avoiding Fumbles: Online Patient Handoff Training
Authors: Wells Jack , Higbee Dena , Doty Jen , Louder Elaine 
Published: October 2020

Introduction: The COVID-19 pandemic required rapid curriculum adaptation to online delivery. Given the importance of accurate clinical patient handoffs, we adapted simulation-based medical student training in clinical patient handoffs. We scored the accuracy of the information students presented. We also elicited student feedback to determine their perceptions of the event and their evaluations of the effectiveness of the training.
Methods: Twenty-six third-year medical students participated online via Zoom. Students participated in groups of three or four students. They sequentially encountered a standardized patient. Clinical information and physical exam findings were handed off from student to student until the encounter was complete. The student group then debriefed with faculty. Students were evaluated based on the proportion of clinical information handed off to the following student. Students also evaluated the training session.
Results: The first student handoff included 73.4% of the available information. In subsequent handoffs, the percentage fell to 43%. All students said they felt the training was helpful in practicing patient handoffs and interactions with colleagues. Negative student comments focused on perceived deficiencies in session planning and standardized patient training.
Conclusions: This rapidly developed simulation session demonstrated that clinical training in patient handoffs can be adapted to an online environment. In order to ensure success, faculty should carefully consider logistical adjustments required to transition from a patient contact setting to an online environment. Meticulous preparation and attention to detail will ensure that training is successful.
