Published: April 2023

Background and purpose

In breast cancer patients, the increasing de-escalation of axillary surgery and the improving resolution of diagnostic imaging results in a more frequent detection of residual, radiographically suspect lymph nodes (sLN) after surgery. If resection of the remaining suspect lymph nodes is not feasible, a simultaneous boost to the lymph node metastases (LN-SIB) can be applied. However, literature lacks data regarding the outcome and safety of this technique.

Materials and methods

We included 48 patients with breast cancer and sLN in this retrospective study. All patients received a LN-SIB. The median dose to the breast or chest wall and the lymph node system was 50.4 Gy in 28 fractions. The median dose of the LN-SIB was 58.8 Gy / 2.1 Gy (56-63 Gy / 2-2.25 Gy). The brachial plexus was contoured in every case and the dose within the plexus PRV (+0.3-0.5mm) was limited to an EQD2 of 59 Gy. All patients received structured radiooncological and gynecological follow-up by clinically experienced physicians. Radiooncological follow-ups were at baseline, 6 weeks, 3 months, 6 months and subsequent annually after irradiation.

Results

The median follow-up time was 557 days and ranged from 41 to 3373 days. Overall, 28 patients developed I°, 18 patients II° and 2 patients III° acute toxicity. There were no severe late side effects (≥ III°) observed during the follow-up period. The most frequent chronic side effect was fatigue. One patient (2.1 %) developed pain and mild paresthesia in the ipsilateral arm after radiotherapy. After a follow-up of 557 days (41 to 3373 days), in 8 patients a recurrence was observed (16.7%). In 4 patients the recurrence involved the regional lymph node system. Hence, local control in the lymph node drainage system after a median follow-up of 557 days was 91.6 %.

Conclusion

If surgical re-dissection of residual lymph nodes is not feasible or refused by the patient, LN-SIB-irradiation can be considered as a potential treatment option. However, patients need to be informed about a higher risk of regional recurrence compared to surgery and an additional risk of acute and late toxicity compared to adjuvant radiotherapy without regional dose escalation.
Improving child health service interventions through a Theory of Change: A scoping review
Authors: Jones Benjamin , Paterson Amy , English Mike , Nagraj Shobhana
Published: April 2023

Background

The objective of this scoping review was to map how child health service interventions develop, utilise, and refine theories of change. A Theory of Change (ToC) is a tool for designing, implementing, and evaluating interventions that is being increasingly used by child health practitioners who are aiming to enact change in health services.

Methods

A published protocol guided this scoping review. Relevant publications were identified through selected electronic databases and grey literature via a search strategy. The main inclusion criteria were any child health service intervention globally that described their ToC or ToC development process. These were applied by two independent reviewers. Data relevant to the research sub-questions were extracted, charted and discussed.

Findings

38 studies were included in the analysis. This scoping review highlights the disparate and inconsistent use, and reporting of ToCs in the child health service intervention literature.

Conclusion

A ToC may be a helpful tool to enact change in a child health service but careful consideration must be undertaken by the child health service regarding how to maximise the benefits of doing a ToC, and how to accurately report it.

Published: April 2023

Background: Chronic kidney disease (CKD) is usually insidious, and most affected individuals are asymptomatic until the disease becomes advanced. The effective treatment of CKD would rely on the incorporation of multidisciplinary approaches. Astragalus membranaceus (AM) and Curcuma zedoaria (CZ) have been widely used in the treatment of CKD. However, the mechanism of AM and CZ in the treatment of CKD is still unclear.

Methods: This study was designed to evaluate the effects of AM and CZ on adenine-induced rats and to investigate the underlying mechanism by using metabolomic analysis. Addition of 0.75% adenine to the diet of rats for 3 weeks induced the animal model of CKD. The rats in the treatment group were treated with AM and CZ (2.1 g/kg/day) for 4 weeks. Blood and kidney samples were collected for biochemical and histological examination. Ultra-high-performance liquid chromatography/Q Exactive HFX mass spectrometer (UHPLC-QE-MS) was applied to analyze metabolic profiling variations in the kidney.

Results: The results showed that AM and CZ could significantly reduce serum creatinine (Scr) and blood urea nitrogen (BUN) levels in CKD rats and alleviate renal pathological injury. By comparing the endogenous components of the normal group and the model group in positive ion mode and negative ion mode, a total of 365 and 155 different metabolites were screened, respectively. A total of 117 and 73 metabolites with significantly different expressions were identified between model group and AM and CZ group in positive ion mode and negative ion mode, respectively. The pivotal pathways affected by AM and CZ included nicotinate and nicotinamide metabolism, and glycine, serine and threonine metabolism. Furthermore, significant changes in metabolites in CKD rats after AM and CZ therapies were observed, including L-Threonine, D-pantothenic acid, and nicotinamide. Moreover, we found that AM and CZ significantly reduced renal fibrosis and inflammation in CKD rats, which may be related to the regulation of SIRT1/JNK signaling pathway.

Conclusion: In conclusion, AM and CZ significantly reduced renal fibrosis and inflammation in CKD rats, which may be related to the regulation of SIRT1/JNK signaling pathway. Furthermore, L-Threonine, D-pantothenic acid, and nicotinamide may be potential biomarkers for the progression and treatment of CKD.

A mini review of communicative language testing
Authors: Liao Linyu , Ye Shelly Xueting , Yang Jinsong
Published: April 2023

Compared with traditional language testing, which heavily emphasizes psychometric reliability, communicative language testing (CLT), which uses authentic tasks to measure communicative abilities, has long been dominant in language assessment. Given its widely acknowledged advantages and widespread use, CLT has become less controversial in the language assessment field and thus is receiving decreased scholarly attention. However, real-world communication, in which CLT is grounded, evolves over time, suggesting the need to update our understanding of it. To address this need and facilitate the further development of CLT theories and practices, this paper offers an up-to-date review of CLT, including its various approaches, implementation challenges, and suggestions for future research.

Authors: Fan Tingting , Wang Jiaxin , Li Luyao , Kang Jing , Wang Wenrui , Zhang Chuan
Published: April 2023

Objective

The purpose of this study was to develop and validate a predictive model based on a machine learning (ML) approach to identify patients with DKA at increased risk of AKI within 1 week of hospitalization in the intensive care unit (ICU).

Methods

Patients diagnosed with DKA from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database according to the International Classification of Diseases (ICD)-9/10 code were included. The patient’s medical history is extracted, along with data on their demographics, vital signs, clinical characteristics, laboratory results, and therapeutic measures. The best-performing model is chosen by contrasting the 8 Ml models. The area under the receiver operating characteristic curve (AUC), sensitivity, accuracy, and specificity were calculated to select the best-performing ML model.

Results

The final study enrolled 1,322 patients with DKA in total, randomly split into training (1,124, 85%) and validation sets (198, 15%). 497 (37.5%) of them experienced AKI within a week of being admitted to the ICU. The eXtreme Gradient Boosting (XGBoost) model performed best of the 8 Ml models, and the AUC of the training and validation sets were 0.835 and 0.800, respectively. According to the result of feature importance, the top 5 main features contributing to the XGBoost model were blood urea nitrogen (BUN), urine output, weight, age, and platelet count (PLT).

Conclusion

An ML-based individual prediction model for DKA-associated AKI (DKA-AKI) was developed and validated. The model performs robustly, identifies high-risk patients early, can assist in clinical decision-making, and can improve the prognosis of DKA patients to some extent.

Authors: de Sousa Letícia Cristina Machado , Silva Nathalia Rabello , Azeredo Catarina Machado , Rinaldi Ana Elisa Madalena , da Silva Luciana Saraiva
Published: April 2023

Objective

The aim of this study was to identify patterns related to health and their association with chronic kidney disease (CKD) in the Brazilian population.

Methods

We used data from the National Health Survey (PNS), 2019. Participants were interviewed and answered questions related to socioeconomic and demographic information (gender, age, education, race/color), health conditions (presence of hypertension, diabetes mellitus, hyperlipidemia, cardiovascular disease, overweight and CKD) and lifestyle (smoking, alcohol consumption, physical activity and food consumption). To identify patterns, we used exploratory factor analysis. We performed logistic regression models to describe the association of CKD with each pattern in crude models and adjusted for gender, age group, education level and race/color.

Results

A total of 90,846 individuals were evaluated. The prevalence of CKD was 1.49% (95% CI: 1.3–1.6). Three health-related patterns – metabolic factors, behavioral risk factors and behavioral protective factors – were identified by factor analysis. Metabolic factors were determined by the presence of hypertension, diabetes mellitus, hyperlipidemia and cardiovascular diseases. Behavioral risk factors were determined by smoking, alcohol consumption, regular consumption of soft drinks, sweets and artificial juices, and high salt consumption. The protective behavioral factors were established by the practice of physical activity and regular consumption of vegetables and fruits. Participants of the highest tertile for metabolic factors were more likely to have CKD in the adjusted model (OR = 3.61, 95% CI: 2.69–4.85), when compared to those of the lower tertile.

Conclusion

The pattern referring to metabolic factors was associated with a higher chance of presenting CKD.
Optimizing aged care environments to promote resident functional mobility and reduce staff injury risk
Authors: Coman Robyn , Caponecchia Carlo
Published: April 2023

Introduction: This study aimed to evaluate the suitability and usability of the Pro-Mobility patient/person handling assessment tool (ProMob) within residential aged care. Physiological changes associated with ageing influence an older person’s ability to perform functional mobility tasks such as transferring from furniture and walking. Strategies that improve capability and/or reduce the physical demands of the task have the potential to promote an older person’s mobility, independence and wellbeing. Environment-related strategies in Manual Handling of People (MHP), such as optimum seated heights, in part address this challenge, as they can promote resident functional mobility while also protecting staff from injury. The ProMob tool was developed to address this issue through systematic evaluation of these environmental factors.

Methods: The participants in this study were seven (7) residential aged care facilities (RACFs) operated by a not-for-profit aged care organization. A qualified assessor evaluated MHP risk management with the ProMob tool at each RACF through collection of data for a random sample of residents (n = 67) regarding their living environments and available mobility information. Data was transferred to an SPSS-22 statistical software database for analysis which involved descriptive statistics and cross tabulations.

Results: Application of the ProMob tool provided effective quantification of the nature and extent of environment-related MHP interventions that may influence resident mobility. Areas for improvement with MHP risk management were identified, with variation evident across RACF’s within the same organisation, which was not consistent with levels of care (e.g., lack of clear space to facilitate mobility). Low level care facilities were observed to have fewer adaptive environmental features that could potentially slow decline in independence.

Discussion: Features of the aged care environment can be used to facilitate the functional mobility of aged care residents, and simultaneously reduce injury risk for staff in MHP interactions. The ProMob tool can be used for auditing care facilities, planning re-development, and continual improvement in provision of care and management of staff injury risk exposure.

Microbial-based biological treatments improved the nutritional, nutraceutical and functional properties of greenhouse sweet pepper (Capsicum annuum L.)
Authors: Tahmasebi Aminallah , Mirzaalian Dastjerdi Abdolmajid , Jamali Babak
Published: April 2023

Sweet pepper (Capsicum annum) is an important vegetable with high economic and nutritional value. The present study was conducted to evaluate the effectiveness of biological treatments on the nutritional, nutraceutical and functional status of greenhouse sweet peppers cv. Nirvin. Plants were divided into two categories: Peppers that were biologically treated included five microbial-based fertilizers and insecticide and those that were chemically treated contained a large number of chemical fertilizers and pesticides. The results showed that the total phenolic content, antioxidant activity, and leaf chlorophyll content were significantly higher (1.16, 1.14, and 1.09-fold) in the biologically treated plants compared to those that received the chemical treatment. The concentration of Fe, K, Mg, P, Ca, Cu, Si, and Mn also increased in the fruits of biologically treated sweet pepper plants. Fe, Mg, and P content of the leaves was higher in the chemically treated plants, while, the concentration of Zn and Cu showed the higher values in the leaves of the biologically treated plants. There was no significant difference between biological and chemical treatments in plant height as well as the number of flowers and fruits per plant. In conclusion, biological treatment could significantly improve the nutritional, nutraceutical and functional values of sweet peppers. Considering the risk of environmental pollution, the high cost of chemical fertilizers and pesticides, as well as their adverse impact on human health and the ecosystem, biological treatment can be a suitable alternative for sweet pepper management programs.

Authors: Rao Jin , Yu Yue , Zhang Li , Wang Xuefu , Wang Pei , Wang Zhinong
Published: April 2023

Background

Lung squamous cell carcinoma (LSCC) is a common subtype of non-small cell lung cancer. Our study aimed to construct and validate a nomogram for predicting overall survival (OS) for postoperative LSCC patients.

Methods

A total of 8,078 patients eligible for recruitment between 2010 and 2015 were selected from the Surveillance, Epidemiology, and End Results database. Study outcomes were 1-, 2- and 3-year OS. Analyses performed included univariate and multivariate Cox regression, receiver operating characteristic (ROC) curve construction, calibration plotting, decision curve analysis (DCA) and Kaplan–Meier survival plotting.

Results

Seven variables were selected to establish our predictive nomogram. Areas under the ROC curves were 0.658, 0.651 and 0.647 for the training cohort and 0.673, 0.667 and 0.658 for the validation cohort at 1-, 2- and 3-year time-points, respectively. Calibration curves confirmed satisfactory consistencies between nomogram-predicted and observed survival probabilities, while DCA confirmed significant clinical usefulness of our model. For risk stratification, patients were divided into three risk groups with significant differences in OS on Kaplan–Meier analysis (P < 0.001).

Conclusion

Here, we designed and validated a prognostic nomogram for OS in postoperative LSCC patients. Application of our model in the clinical setting may assist clinicians in evaluating patient prognosis and providing highly individualized therapy.
A Decentralized LQR Output Feedback Control for Aero-Engines
Authors: Ji Xiaoxiang , Li Jianghong , Ren Jiao , Wu Yafeng
Published: April 2023

Aero-engine control systems generally adopt centralized or distributed control schemes, in which all or most of the tasks of the control system are mapped to a specific processor for processing. The performance and reliability of this processor have a significant impact on the control system. Based on the aero-engine distributed control system (DCS), we propose a decentralized controller scheme. The characteristic of this scheme is that a network composed of a group of nodes acts as the controller of the system, so that there is no core control processor in the system, and the computation is distributed throughout the entire network. An LQR output feedback control is constructed using system input and output, and the control tasks executed on each node in the decentralized controller are obtained. The constructed LQR output feedback is equivalent to the optimal LQR state feedback. The primal-dual principle is used to tune the parameters of each decentralized controller. The parameter tuning algorithm is simple to calculate, making it conducive for engineering applications. Finally, the proposed scheme was verified by simulation. The simulation results show that a high-precision feedback gain matrix can be obtained with a maximum of eight iterations. The parameter tuning algorithm proposed in this paper converges quickly during the calculation process, and the constructed output feedback scheme achieves equivalent performance to the state feedback scheme, demonstrating the effectiveness of the design scheme proposed in this paper.

Published: April 2023

(1) Background: This study aims to assess the diagnostic accuracy of parameters based on a combination of transcranial magnetic stimulation (TMS) and electrical stimulation (ES) in the differentiation between idiopathic and secondary facial palsy in a large cohort of patients. (2) Methods: Patients with unilateral facial palsy ≤7 days after symptom onset were included. Compound muscle action potential (CMAP) amplitudes were measured after stimulation of both facial nerves at (A) the internal acoustic meatus using TMS, CMAP-TMS, and (B) at the stylomastoid foramen using electrical stimulation, CMAP-ES. To express the degree of nerve dysfunction in the facial canal specifically, the amplitude reduction of the CMAP-TMS in relation to CMAP-ES was calculated and expressed as a percentage (amplitude reduction over the facial canal, ARFC). Receiver Operating Characteristic (ROC) curves were constructed to assess the diagnostic accuracy of ARFC as a marker to discriminate between patients with idiopathic and secondary facial palsy. (3) Results: Data from 498 patient records were analyzed. Idiopathic facial palsy was diagnosed in 424 patients, and secondary facial palsy in 74 patients. The area under the ROC curve for ARFC was 0.398. (4) Conclusions: The overall diagnostic accuracy of this method to differentiate secondary from idiopathic facial palsy is low.
Curricular Innovation for Food Security
Authors: Castillo Escalante Irma Cecilia , Ramírez García Adán Guillermo
Published: April 2023

The curriculum is a dynamic and continuous process that must be adapted to the requirements and needs of specific contexts to respond to current problems. Currently, it is estimated that more than 828 million people in the world suffer from hunger, so food security must be based on the production and availability of food and physical and economic access to food, as well as its safety. For the above, this research aims to propose a curricular innovation to the professional competences of the study program of the Agricultural Technician (TAP) that is offered in the Agricultural Technological Baccalaureate Centers to train technicians who contribute to food security in the region. A methodology with a mixed perspective with a qualitative approach and descriptive exploratory character was used. Based on the primary information and data collection, it was possible to specify and substantiate a curricular proposal according to the training needs of specialized technicians, who develop professional skills to promote food security, the establishment of agricultural production system, management of livestock production systems, operation of agro-industrial production system, and the design and execution of projects to promote the cultivation of food from small-scale families.
A Global Review of the Impacts of the Coronavirus (COVID-19) Pandemic on Radiology Practice, Finances, and Operations
Authors: Patel Kishan , Rashid Arnav , Spear Luke , Gholamrezanezhad Ali
Published: April 2023

The Coronavirus Disease 2019 (COVID-19) pandemic ushered in rapid changes in healthcare, including radiology, globally. This review discusses the impact of the pandemic on various radiology departments globally. We analyze the implications of the COVID-19 pandemic on the imaging volumes, finances, and clinical operations of radiology departments in 2020. Studies from health systems and outpatient imaging centers were analyzed, and the activity throughout 2020 was compared to the pre-pandemic activity, including activity during similar timeframes in 2019. Imaging volumes across modalities, including MRI and CT scans, were compared, as were the Relative Value Units (RVUs) for imaging finances. Furthermore, we compared clinical operations, including staffing and sanitation procedures. We found that imaging volumes in private practices and academic centers decreased globally. The decreases in volume could be attributed to delayed patient screenings, as well as the implementation of protocols, such as the deep cleaning of equipment between patients. Revenues from imaging also decreased globally, with many institutions noting a substantial decline in RVUs and revenue compared with pre-COVID-19 levels. Our analysis thus found significant changes in the volumes, finances, and operations of radiology departments due to the COVID-19 pandemic.
Is It Morally Permissible for Some People to Rape and Murder? Responding to Erik Wielenberg’s Argument That Divine Command Theory Fails to Explain How Psychopaths Have Moral Obligations
Authors: Johnson Adam Lloyd
Published: April 2023

Atheist moral philosopher Erik Wielenberg recently argued that Divine Command Theory is implausible as an explanation of objective morality because it fails to explain how psychopaths have moral obligations. In this paper I explain that everyone agrees the consciences of psychopaths don’t work as they should, but there’s disagreement among experts as to whether: A. The consciences of psychopaths don’t inform them of what’s right and wrong and that they should do what’s right or B. The consciences of psychopaths do inform them of these things but merely don’t generate the appropriate moral emotions. I argue that, based on the psychological research, a strong case can be made for B and thus under DCT psychopaths do have moral obligations because their consciences inform them of what’s right from wrong and that they should do what’s right. I also argue that even if A is true, God can, and does, make psychopaths aware of what’s right and wrong and that they should do what’s right through other means such as rationality, society, parents, culture, direct verbal commands, etc. Therefore, even if A is true, then psychopaths still have moral obligations under DCT because they do know what’s right from wrong and that they should do what’s right. Lastly, I turn the tables on Wielenberg and point out that his theory is even worse than DCT when it comes to providing an explanation for the moral rights and obligations of psychopaths
Comparing the Effectiveness of Robust Statistical Estimators of Proficiency Testing Schemes in Outlier Detection
Authors: Tsamatsoulis Dimitris
Published: April 2023

This study investigates the effectiveness of robust estimators of location and dispersion, used in proficiency testing and listed in ISO 13528:2015, in outlier detection. The models utilize (a) kernel density plots, (b) Z-factors, (c) Monte Carlo simulations, and (d) distributions derived from at most two contaminating distributions and one main Gaussian. The simulation parameters cover a wide range of those commonly encountered in proficiency testing (PT) schemes, so the results presented are of fairly general application. We chose a functional sub-optimal solution by grouping and classifying the model settings, resulting in five matrices readily usable for selecting the best robust estimator. Whenever at most half of the distribution of each contaminating population is outside the central distribution, there is only one optimal estimator. For all other cases, the five matrices provide the appropriate robust statistic. The proposed method applies to 95.1% of 144 results for an existing PT for cement. These actual datasets indicate that the Hampel estimator for the mean and the Q-method for the standard deviation provide the most appropriate performance statistic in 86.1% of the cases.

If there are violations in the personal, emotional, needs and motivational spheres, in the presence of unfavorable conditions in life, a teenager increasingly turns to gadgets. When it is impossible to use them, a teenager begins to experience feelings of longing and anxiety. Over time, gadgets for young people turn into a means of escaping real life, in order to relieve tension, for example, after a conflict, quarrel, etc. A long-term use of a smartphone or tablet can provoke the occurrence of physical or mental overstrain, headaches, aggressive behavior, and other destructive manifestations. Consequently, at this stage of the development of society, developing recommendations to prevent and overcome gadget addiction in adolescents is one of the urgent problems in the fields of clinical psychology, psychosocial work, psychiatry, narcology, etc.
The problem of loneliness among women
Authors:   Osh State University, Osh, Rustamova Dilnara Akramovna
Published: April 2023

The relevance of this article lies in the fact that loneliness is quite a common problem in modern society. It affects the well-being of a person, sleep, attention, logical and verbal thinking, causes an immune system disorder and hormonal imbalance, and activates inflammatory processes in the body. Not everyone who experiences loneliness feels alone. As a subjective emotion, loneliness can be felt even when one is surrounded by other people. The fact is that girls from Kyrgyzstan marry at an early age, when they are not yet fully formed as individuals, and this can lead to loneliness. The reasons for this are varied. Loneliness can be the result of a lack of meaningful relationships, significant losses, over-reliance on passive technologies (especially the Internet in the 21st century), or self-perpetuating mindset. Studies have shown that loneliness occurs throughout society, including among people who are married and in strong relationships, as well as among those who have had successful careers. Most people experience loneliness at some point in their lives, and some experience it very often. The consequences of loneliness are also varied. Temporary loneliness (loneliness that exists for a short period of time) is associated with positive effects, including an increased focus on the strength of their relationship. Chronic loneliness (loneliness that exists for a significant period of time in life) is usually associated with negative outcomes, including increased obesity, risk of cardiovascular disease, and risks of high blood pressure and high cholesterol. Chronic loneliness also correlates with an increased risk of death and suicidal thoughts. This article reflects the analysis of the problem of loneliness at the theoretical and empirical level. The results of the analysis showed that married women do not feel lonely compared to unmarried women.

Published: April 2023

The "Third Heraldic Reform" in the Donbass was purely commercial. The craze for collecting badges with coats of arms caused the development of "rural heraldry" in Donbass. At the end of 1995, all the cities of the Donetsk region already had coats of arms, each of them had a technical symbol. Villages, districts, urban-type settlements remained without coats of arms. During the "Second Heraldic Reform", the principles of building coats of arms were constantly violated. The emerging literature on heraldry led to the desire of novice heraldists to use classical heraldic techniques: division of the shield, enamel), heraldic figures, allegories, and historical roots. The implementation of the acquired knowledge was embodied in the creation of coats of arms of small settlements, taking into account the history, directions of economic development, and the search for symbols. reflecting these directions, etc. The problems associated with the lack of legislation allowing a city, town, village to have its coat of arms and the desire to preserve Soviet symbols were quickly overcome. In the industrial region, even villages are involved in industry - mining, energy, and this is reflected in the work of heraldists. The stories about some episodes, stages of this work have become the main content of this article.
State regulation and management of the system of ownership and use of agricultural land. Part II
Authors:   Federal State Budgetary Scientific Institution “All-Russian Research Institute of Agricultural Economics”(VNIIESH), Moscow, Alakoz V.V.
Published: April 2023

A huge country, sparsely populated over large areas, with an abundance of natural resources, inherited from the ancestors, this is a blessing and a burden at the same time - the territory and resources must not only be protected from envious neighbors and countries that are historically accustomed to obtain natural resources at an inexpensive price, but also populate and equip vast territories by establishing production, and not mainly engage in gathering and selling the gifts of nature, constantly being in a state of “lagging development model”. With an abundance of land resources, and at least half of the untapped potential of productive agricultural lands, the ever-increasing need for food in the world creates geopolitical and economic opportunities for increasing agricultural production through a more complete use of vacant agricultural lands of the Non-Black Earth Region and intensification of agriculture in regions with more fertile black soil. Land policy plays a decisive role in realizing the existing opportunities to increase agricultural production, legislation, and the quality of legal regulation of land relations, management of the use of productive agricultural land, institutional environment and land management infrastructure. The article considers long-term problems of land policy, land legislation, the quality of regulation and management of land resources in agriculture and the need to determine ways and means of their improvement. “Administrative labor occupies a dominant position in relation to executive labor, as well as to the services of the land. It forms “the third factor” of production (capital + land + labor. A significant part of capital is knowledge and the organization of production). Labor is as passive as natural objects (for economic theory). Labor and land are just an instrument” (Josef Alois Schumpeter, 1883-1950, Theory of Economic Development, p. 69).

The victory of the August Revolution of 1945 started the era of national independence, civil rights and democracy for Vietnam. Recognizing the importance of land management for national development, the new state, immediately after gaining independence, adopted a new land management and land use policy aimed at stabilizing people's lives and meeting the needs of the entire population. During the 77 years of building and development of independent Vietnam, the country has gone through several historical periods in the development of land relations, and in each of them land administration and, above all, land management made a great contribution to the national revival. In this article, the author considers the main stages in the development of the land sector in the period from 1945 to the present, in order to determine its history as a basis for making guidelines and decisions to further improve the organization and increase the efficiency of land management in the country.

The consolidation of vegetation cover by three classes of soil cover according to the UN classification (grass + shrub + trees) on the territory of the subjects of the Russian Federation is proposed in this article. The assessment of land consolidation is carried out (in descending order) by the total ecological coefficient, which is calculated as the ratio of the vegetation share on land to the share of anthropogenically changed land. The identification method revealed 20 wavelets of the rating. By the authors, the last 46 regions need to radically change the structure of land use.

An eff ective and fi nancially aff ordable method of preventing intestinal disorders, increasing the level of metabolism and increasing the productivity of animals is the use of probiotic drugs. The purpose of the research was to substantiate the use of the microencapsulated probiotic drug “Enzimesporin with enzyme” in feeding pigs of the hybrid of the Canadian breeding Genesus. In order to study the eff ectiveness of the use of the microencapsulated drug “Enzimesporin with enzyme” in the diets of young pigs during rearing and fattening, experimental animals randomized by live weight an sex were divided into the following groups of 20 animals. in each: control (without the introduction of probiotic drugs into the diet), 1st experimental (introduction of the uncapsulated drug “Enzimesporin” into the feed at a dose of 3,0 g/head/day), 2nd experimental (introduction of the microcapsulated drug “Enzimesporin” into the feed at a dose of 3,0 g/head/day), 3rd experimental (introduction of the microencapsulated drug “Enzimesporin with enzyme” into the feed at a dose of 3,0 g/head/day). It was found as a result of the research that the level of profi tability of pork production at the end of the experiment when using the microcapsulated drug “Enzimesporin with enzyme” per 1 head it amounted to 26,43 %, which was higher than in the control group, where the profi tability level was 17,52 % by 8,91 abs.%. The production test showed that the introduction of the microcapsulated drug “Enzimesporin with enzyme” into the main diet signifi cantly aff ected the productivity of the animals of the experimental group. Thus, the average live weight of pigs taking the studied drug was 9,2 kg more than in the control or 11,0 %. It is possible to recommend on the base of the conducted studies, the microencapsulated probiotic drug “Enzimesporin with enzyme” for use as a feed additive to the main diet of pigs of the Canadian selection Genesus at the dose of 3,0 g/head/day.

The purpose of the work was to increase the meat productivity of sheep when introducing granulated mineral complexes produced by the Azot Branch of URALCHEM JSC into their ration. A scientific and economic experiment was carried out on the herd of sheep of Volgograd meat and wool breed. Four groups of young rams with 10 heads in each were formed. The experiment was carrier out for 4 months – from 4 to 8 months of animal age. The animals of the control group were housed on a general farm ration. Their analogues from the experimental groups were fed a mineral compensating additive instead of the mineral part of the ration: the 1st experimental group recipe No. 1, the 2nd experimental group recipe No. 2 and the 3rd experimental group recipe No. 3. It was revealed during the physiological experiment that the organism of animals from the experimental groups compare with the control group absorbed nitrogen obtained with compound feed somewhat better. The highest nitrogen utilization rate was found in sheep that consumed the mineral granulated balancing additive made according to recipe No. 1. It was found that the sheep of the experimental groups, whose rations included the mineral granulated balancing additive had a higher growth rate. The best results were obtained when using the mineral complex made according to recipe No. 1. The profi t from the sale of mutton produced during the experimental period in the 1st, 2nd and 3rd experimental groups exceeded that in the control group by 224,9; 114,5 and 73,8 rubles. The level of profi tability of meat production in the experimental groups was higher than that of the herdmates of the control group by 11,21, 6,41 and 4,10 abs.%, respectively. Thus, in order to increase the meat productivity of young rams we recommend using a diet using mineral granulated complexes. We consider the most optimal complex made according to recipe No. 1.

Communication skills in students is one of the important assets to improving the soft skills of conveying messages to others. The things that support a student to convey messages well are the ability to understand information well, and the ability to convey the message back to other parties. This also applies when someone is studying a foreign language, especially Japanese. If we do not have good communication skills, the information will not be conveyed properly. This study aims to describe the Japanese language communication skills of students in the Japanese Language Education Study Program, Universitas Negeri Semarang. This communication capability is carried out in the form of Saiwa activities or retelling information or news that has been listened. The research methodology used is to use self-help activities or retelling the news that students have listened. To measure this ability is done by means of presentation tests and interview tests.
