ПРИНЦИПЫ НАПИСАНИЯ И ОЦЕНКИ НАУЧНОЙ СОСТОЯТЕЛЬНОСТИ ДИССЕРТАЦИЙ
Authors: Дятлов Александр Викторович , Ковалев Виталий Владимирович , Воденко Константин Викторович
Published: February 2022

Аннотация. Сформулирован и обоснован ряд принципов написания и оценки диссертаций, соблюдение которых позволит повысить уровень научной состоятельности диссертационных проектов, защищаемых в Южном федеральном университете. К их числу относятся: активность диссертационного совета в подготовке кадрового резерва, единство теории и практики, практикоориентированность, детерминированность изложения, ясность изложения. Авторы приходят к мнению, что в сложившейся ситуации (давление менеджеристских технологий на науку, снижение интеллектуального потенциала российского социума, падение профессиональной дисциплины, деформация научной этики) диссертационный совет не может быть простым реципиентом внутренних и внешних диссертаций. Его роль в оценке диссертаций должна приобретать решающее значение, что предполагает отход от формально-постановочных защит, подтверждающих решения, принятые на кафедрах во время предварительных обсуждений диссертационных текстов.

Published: February 2022

The collection of (human) tissue is essential for many aspects of biomedical research. In order to maintain tissue quality and achieve reproducible and representative results, it is critical that the tissue is collected in a consistent manner, especially when tissue is collected by different people, at different locations, and/or over a long period of time. This is particularly important for snap-frozen tissue, which can be stored for long periods of time before use in a range of experiments including bulk and single nucleus RNA sequencing and imaging. Therefore, this protocol for the collection of snap-frozen tissue provides a set of reproducible steps, including recommendations for pictures to be taken and specific details to be noted down, to ensure that consistent tissue collection, such that the collected tissue can be optimally used in the future.

Authors: Amri Faris
Published: February 2022

Length of stay shows the level of management efficiency and quality of care provided by the hospital. The length of stay from the economic aspect for the patient will increase the cost of care that they have to pay. Characteristics, nosocomial infections, complications, and wound healing can affect the patients' length of stay. This study aims to analyze the correlation between characteristics and nutritional status with the length of stay of ICU patients in Purwakarta. This study is a quantitative analytical study using secondary data, namely the patient's medical record. The accidental sampling technique selected a total of 80 patient data in this study. The variables studied were gender, age, occupation, type of diagnosis, nutritional status, and length of stay. Data were analyzed using chi-square. The results of the analysis using the Chi-square test showed that there were three variables related to the length of stay of ICU patients, namely age (p = 0.040), type of disease (p = 0.005), and nutritional status (p = 0.047). Gender (p=0.96) and occupation (p=0.234) were not related to the length of stay of ICU patients. Age, type of diagnosis, and nutritional status related to the length of stay of ICU patients. Hospitals need to provide exceptional services to elderly and malnourished patients to speed up the healing process.

Stunting in Indonesia: Why is it Increasing?
Authors: Insani Handayani Madania
Published: February 2022

The incidence of stunting in Indonesia has increased by 2.1% according to data presented by Basic Health Research in 2018 with a total percentage of 27.5% in 2016 and increased to 29.6% in 2017. This study is a descriptive study with a systematic review method. . Seeing the causes and prevalence of stunting as well as government and community efforts in tackling stunting is the goal of this study. The results showed that stunting cases in 2018 increased by 2.1% to 29.6%. Stunting in Indonesia is mostly caused by difficulty in accessing nutritious food, lack of exclusive breastfeeding, low birth weight (LBW) and low education level and parental income. The government has made various efforts such as intervention in various sectors, however, the incidence of stunting is still quite high. Thus, to tackle the incidence of stunting, collaboration with the community is needed to be more concerned and aware of knowledge related to balanced nutrition, especially for pregnant women, maternity mothers, toddlers and children.
Hydration In Athletes: A Literature Review
Authors: Fauza Ahdiyatul , Astuti Widya
Published: February 2022

The aim of this study to review the most recent research on the factors that most influence hydration. This study review using the literature research from google scholar, PubMed, and Elsevier. Many athletes after training experience dehydration due to not consuming enough fluids and electrolytes before, during training, and competition. To assess hydration status cannot be determined by just one factor. The general recommendation of hydration status measures using accurate biomarkers to detect body water fluctuations of 3% of total body water (TBW), using dehydration index, body mass, or color of urine. Therefore, monitoring hydration status is very important to maintain athlete performance. Exercise increases hypohydration due to fluid losses so that should be given to fluid supplementation and intake from certain food for each athlete. The factor that most influences the athlete's hydration is sweat loss and fluid intake.

La responsabilidad jurídica de los programadores por los daños causados por agentes autónomos
Authors: Zornoza Somolinos Alejandro
Published: February 2022

El sistema de Derecho español no se elaboró para contemplar la presencia de agentes autónomos. Ante cualquier daño que éstos produzcan, los juristas nos vemos obligados a aplicar los mecanismos tradicionales de imputación de responsabilidad y riesgos y, en consecuencia, se concluye que el programador de un agente autónomo es el responsable único y absoluto de los daños producidos por el comportamiento autónomo del agente. Por insólito que parezca, esta realidad se ve especialmente agravada cuando el daño se ha debido al correcto funcionamiento del agente autónomo, ya que entre su comportamiento esperado y el daño producido, existe una relación de causalidad que impide la exculpación del programador.

Published: February 2022

Este trabajo presenta el diseño de un sistema de control de estabilización de un buque de alta velocidad (BAV) para mejorar el confort y seguridad en el transporte marítimo. El objetivo es conseguir la amortiguación de las dinámicas acopladas de arfada, cabececeo y balance mediante el uso de superficies de estabilización activa (aletas de proa, de popa y laterales). La metodología empleada se basa en la técnica de control robusto en el dominio de la frecuencia denominada Teoría de la Realimentación Quantitativa QFT (Quantitative Feedback Theory). En este trabajo se van a presentar dos aproximaciones, dependiendo del nivel de acoplamiento debido a la acción de los actuadores. En la primera solución, se considera un nivel de acoplamiento bajo y se diseñan de forma separada los controladores para las dinámicas longitudinal y transversal. En la segunda solución, se considera un nivel de acoplamiento alto debido a la acción de los actuadores. En este caso se emplea una combinación de la técnica QFT y Asignación de Autoestructuras (AE). Para las dos aproximaciones, los análisis de las simulaciones temporales para diferentes estados de la mar y ángulos de incidencia del oleaje demuestran resultados satisfactorios y se consigue el amortiguamiento. Se demuestra con ello que las técnicas de control robusto basadas en las metodologías QFT resultan factibles y apropiadas para el control de estabilización de sistemas marinos avanzados, pues resuelven la problemática en diferentes velocidades y ángulos de incidencia.

Published: February 2022

Cordyceps militaris is an insect parasitic fungus with high medicinal value similar to Cordyceps sinensis and has great economic value. Ensuring the balance between the biomass and the bioactive potential of C. militaris plays an important role in the development of quality products from this medicinal fungus. In this study, nitrogen sources (fresh silkworm pupae, peptone, yeast extract) with different concentrations were used to evaluate the effect on yield, morphology and content of cordycepin, adenosine of C. militaris. The results showed that the N1 medium using 20 g\L fresh silkworm pupae, 0.5g\L KH2PO4 and 0.5g\L MgSO4 gave the highest yield and active ingredient content, with cordycepin yield of 17.01 mg\jar. Adding carbon sources (glucose and sucrose) at concentrations (10, 20, 40 g\L) to N1 medium can shorten the time of filamentous spreading and the time of fruit body formation, but significantly reduce cordycepin content. This result has important implications for medium optimization for C. militaris culturing.
The operculate land snail genus Dioryx (Gastropoda: Alycaeidae): Data for Vietnam and an up-to-date checklist of species in the world
Authors: Do Duc Sang , Nguyen Thanh Son , Nguyen Duc Hung
Published: February 2022

The land area of Vietnam is composed of a large variety of undisturbed habitats, such as high mountainous areas, forests over limestone, limestone karsts, and especially the Truong Son mountain range. Therefore, Vietnam is expected to have a high species diversity, especially for the terrestrial snails. Species of Dioryx have been recognised as occurring from the southeastern Himalayan region to Taiwan (China) in the east, and down to the northern part of the Malay Peninsula. This genus is characterised by shell small to medium, globose; protoconch smooth, not spirally striated; Region 1 (R1) usually very finely reticulated due to fine radial ribs and fine spiral striation, or smooth; R2 short to long, usually without ribs. The Vietnamese members of the genus Dioryx are reviewed, and a checklist of all Dioryx species is provided. Eight species are recognised from Vietnam, in which, seven species were recorded from the Northern and North Central, and one species (Dioryx cochinensis) from the Southern.

Authors: Tran Duc Hau , Dang Thi Thanh Huong , Ta Thi Thuy , Ngo Thanh Xuan
Published: February 2022

The genus Pareuchiloglanis (Siluriformes: Sisoridae) consists of 26 species in the world. In Vietnam, this genus has eight species, including five that are in uncertain taxonomy status. In the present study, we described one species of Pareuchiloglanis based on collections from the Da River basin in Phong Tho district, Lai Chau province. Pareuchiloglanis sp. can be distinguished from congeners by the following unique combination of characters: D. i,6; A. i,4; P1. i,14-16 (primarily i,16); C. i,6-8,6-8,i (primarily i,8,8,i); interorbital distance\eye diameter 2.4-3.4; caudal peduncle length 17.1-21.5; caudal pedunle depth 6.0-7.0% SL; length of adipose base\dorsal to adipose distance averaged 1.8; head length 19.2-24.3; anal-fin origin closer to the anus than to the caudal-fin base; adipose-fin base posterior to the tip of pelvic-fin rays; the pelvic-fin insertion located opposite to the fourth dorsal fin-ray element; maxillary barbel extending just beyond base of first pectoral-fin element; and yellow patches on dorsal surface (a broader pair on the last doral-fin ray, as large as two thirds length of pelvic-fin). Morphological analysis showed that Pareuchiloglanis sp. are closed to two species in the same surveyed area, P. tamduongensis and P. songdaensis. This paper also indicated morphological differences between Pareuchiloglanis sp. and other species that have yellow patches on dorsal surface. This species record implied the potential of biodiversity of Pareuchiloglanis in the headwaters of the Red River. These findings provide worthy data for further studies on taxonomy of this genus in northern Vietnam.

This study aims to evaluate the growth and dry matter accumulation of stevia grown in lighting conditions with different spectral ratios, thereby finding the most suitable lighting rate. Materials are stevia stalks cultured in shoot medium, including: MS base supplemented with 20 g\Lsucrose; 8 g\Lagar; 0.15 mg\LBAP, 0.2 mg\LNAA, cultured for 4 weeks under a LED system with different color light ratios, using the following formulas: 40% red + 20% blue + 40% orange (CT1), 20% red + 20% blue + 60% yellow (CT2), 72% red + 14% blue + 14% white (CT3) and 80% red + 20% blue (CT4) and the control formula was the formula of fluorescent lamp irradiation (DC). Formula CT4 gave a result of 100% shoot formation, the average height of shoots was 48.5 mm\shoot and the shoots were the best in quality. Rooting medium included: MS basal supplemented with 15 g sucrose, 8 g\Lagar, 0.2 mg\LNAA for 4 weeks. The results also showed that the CT4 lighting formula was the most suitable for the photosynthesis and growth of cultured stevia in the rooting stage. The seedlings from this lighting system when grown in the net house were able to survive and grow better than the plants from the other lighting conditions.
Study on the distribution of Derris trifoliata Lour. in Giao lac Commune, Giao thuy District, Nam dinh Province
Authors: Vuong Ngoc Thuy , Nguyen Thi Hong Lien , Tran Thi Loan
Published: February 2022

Derris trifoliata is a species which participate in mangrove ecosystem. Species’s distribution depends on many factors, the most important of which is soil structure. Derris trifoliata grows well on clay loam soil or sandy loam soil. Firm ground is less favorable for true mangrove species, so the abundance found along sea-dykes, coastal areas and aquaculture lagoons is much higher than in mangrove core zone. On sandy soil or light sandy loam soil, when sand percentage is high, plants grow poorly with very low density. Study results show that Derris trifoliata can grow on many different types of substrates, but mostly on soil with sand percentage from 39 to 50%, clay from 39 to 45% and limon about 10%. Derris trifoliata grows near sea dykes and aquaculture lagoons, the nearer it is towards sea, the lower abundance and density is. Other ecological factors such as humus content, total nitrogen, C:N ratio, and salinity also affect the distribution of Derris trifoliata but to a lesser extent. In places with high density of Derris trifoliata, although the amount of humus in the soil is not much, the average nitrogen content is high because Derris trifoliata belongs to Fabaceae family, nodules lumps formed on their roots by Rhizobium can fix nitrogen from atmospheric nitrogen.

Preparing and teaching a biological subject oriented STEM education
Authors: Doan Van Thuoc , Nguyen Duc Anh , Tran Thi Dinh
Published: February 2022

STEM education is a teaching and learning approach that integrates all four disciplines (science, technology, engineering, and mathematics) into a single. STEM education gives students opportunities to see the connection between the content they are studying and the application of that content in the real-world. However, this is a new teaching philosophy that is not widely applied for teaching in Vietnam. In order to make STEM education become familiar with Biology teachers, in the present study we suggest 8 steps for preparing a biological subject and 7 steps for teaching the prepared subject oriented STEM education. We hope that this paper will be usefull for Vietnamese teachers, particularly teachers in Biology.
