Water hyacinth is a weed in Rawa Pening because of its rapid growth. A handling effort is a very crucial thing and must be done immediately. This study aims to characterize organic compounds in liquid smoke from dried water hyacinth. ­­­­Characterization of organic compounds from dried water hyacinth was carried out on water hyacinth liquid smoke which was pyrolyzed at 200°C and 600°C. Pyrolysis times were run at 2 hours and 6 hours. Liquid smoke from dried water hyacinth was distilled before testing its chemical composition using GCMS brand Shimadzu type QP 2010S. The results of liquid smoke characterization are used to decide that liquid smoke can be utilized as a food preservative. The test results report that the liquid smoke produced had an acid percentage ranging from 29.63% to 37.23%, phenol from 1.04 to 6.11%, and the remaining carbonyl compounds from 55.99% to 68.90%. The highest component value was obtained at 600°C pyrolysis and 6 hours. The conclusion is that liquid smoke from dried water hyacinth can be used as a food preservative because it contains acid, phenol, and carbonyl and is free of Benzo (a) pyrene, which can cause cancer. So that the requirement for liquid smoke as a preservative can be achieved, whereas acid is a food preservative. This study generates the acquisition of natural food preservatives to utilize weeds. The research helps us utilize weeds to resist the Rawa Pening environment and manufacture food preservatives.

Disaster mitigation material in geography learning requires not only critical thinking skills but also independence and optimism from students. In this regard, the effective approach needed relies not only on theory but also on practice in independent assignments and exercises. It makes limited face-to-face learning, which has been applied recently, unable to optimize learning outcomes. This study aims to analyze the impact of flipped classroom learning based on disaster map visualization on students' self-efficacy and critical thinking skills in disaster mitigation materials. The study used a quasi-experimental design with a pretest-posttest control group design. The research sample consisted of the experimental class (30 students) and the control class (30 students), which were determined randomly after the equivalence test. Data on critical thinking skills were collected using a test method in 10 description items, and self-efficacy data were collected using a questionnaire consisting of 30 statements. The data were analyzed using quantitative descriptive and inferential statistical analysis with MANOVA. The results show a significant effect simultaneously or partially with the sig value. 0.05, so it can be concluded that there is an effect of flipped classroom learning based on disaster map visualization on students' self-efficacy and critical thinking skills in disaster mitigation materials.

Purpose. To create stocks of age-1 and 1+ carp produced with the use of defrosted and native sperm and provide the comprehensive characteristics of their quantitative and qualitative parameters. Methodology. The material for the study were age-1 and 1+ Nyvky scaly and non-scaly carp. Main quantitative and qualitative parameters were studied during spring assessment and autumn harvest using conventional aquaculture methods. Stocking density of age-0+ fish for wintering was 10 thousand kg/ha, age-1 fish – 1 thousand fish/ha. The exterior assessment of multiple age groups was carried out using following parameters: body weight and length, body depth, body circumference. Measurements were done using a measuring tape with a precision of 1 mm. Fish were weighed individually on electronic balances with a precision of 1 g. Following main exterior indices were determined and analyzed: circumference index, body length to depth ratio, head index. Findings. The study showed that age-1 fish produced from defrosted sperm had 0.25 and 4.5% higher survivability during wintering with the prevalence of non-scaly carp, however they were characterized by higher weight loss: 1.13% for scaly carp and 1.65% for non-scaly carp. Age-1+ fish produced from defrosted sperm prevailed over their age-0+ by weight by 2.69% for scaly carp and by 7.34% for non-scaly carp. However, fish of the experimental group were characterized by lower survivability by 1.0% and 3.25% compared to the control group. Fish productivity parameters during the study period varied from 810.7 to 1056.0 kg/ha. Originality. For the first time in Ukraine, a comparative analysis of quantitative and qualitative parameters of age-1 and 1+ carp produced with the use of defrosted and native sperm was performed. Practical value. Use of the method of cryopreservation of sperm obtained from brood fish with desired peculiarities of genotype allows improving creation of highly productive stocks using methods of individual selection, getting highly productive crosses as well as hybrids between geographically isolated populations. Key words: carp, defrosted sperm, age-1 fish, age-1+ fish.

Status and solutions of malicious complaints
Authors:   The Institute of Legal Studies, Kyunghee University, Yun Young Suk
Published: July 2022

In Korea, malicious complaints that go beyond common sense are continuously occurring. Considering that Korea is a leading country in terms of security, the serious level of malicious complaints deserves attention.
Malicious complaints appear in many different forms. They are broadly classified into violent ones, meaningless and repetitive ones, sexual harassment ones, and those due to mental illness. Malicious civil complaints, regardless of their forms, have serious adverse effects on public officials physically and psychologically, lower national administrative power, and cause damage to the entire citizens by interfering with the handling of normal complaints. Many cases and statistics warn that criminal malignant complaints have reached a critical level.
Traditionally, in Korea, acts of private persons who challenge public authority were not severely punished and tended to be handled mainly from a paternalistic perspective. The continuation of these judicial practices gradually lowered the authority of the dignity of public authorities, and the weakened public authorities again provoked malicious complaints, forming a vicious cycle.
Korea is a relatively stable country, where the state or local governments are unable to wield power private persons and pressure them recklessly. Submission of the legitimate exercise of public authority to unreasonable malicious complaints by private persons should be discouraged. Since the existing sentencing standards were set too low for the seriousness of this crime, the first measure to be considered is severe punishment for the offense of vicious obstruction of performance of official duties. In addition, public officials, with the help of investigative agencies or legal experts, need to actively take legal action against the various criminal acts of complainants rather than enduring them unconditionally. The central government, local governments, and public institutions should break away from the practice of accepting only the views of malicious complainants with goodwill and take effective measures to protect public officials. Other measures that may be effective include physical blocking of access and entry of malicious complainants, and the installation of a barrier between malicious complainants and public officials at counseling windows.
It is true that the public officials are servants of the people, but here the people refer to the whole elements that make up the nation, meaning that not all private persons reign over public officials. The mentality of malicious complainants that the public officials should do everything as civil want while recognizing them as subordinates or slaves is extremely regressive and childish. Establishing the right direction of Rule of Law through strict education for these maladaptive citizen is considered as one of the duties of the state and local governments.

Background: The assessment of elite athletes after SARS-CoV-2 infection gives rise
to doubts concerning return-to-play decisions: what period of convalescence is needed
and what diagnostic measures are appropriate. While cardiovascular protocols have been
widely discussed in the literature, lung parenchyma imaging was only briefly mentioned,
and the usefulness of lung ultrasound has been not considered yet. Materials and
methods: A total of 31 elite Caucasian male athletes (mean age: 26.03 ± 5.62), recovered
from COVID-19 were assessed after SARS-COV-2 infection. Medical data was collected. Lung
ultrasonography and highresolution computed tomography were performed. Results: Normal
lung parenchyma dominated on CT scans. A total of 25 athletes (80.6%) presented
abnormalities on high-resolution computed tomography; changes typical for COVID-19 were
detected in five cases (16.1%), and less specific abnormalities were identified in 20
athletes (64.5%). Despite the prevalence of ultrasound abnormalities, A-line pattern was
dominant in 23 athletes (74.2%): for 434 ultrasound-scans, it was visible in = 265
(61.1%). In 93.2% of the subjects, it corresponded to a normal lung parenchyma pattern
visible on high-resolution computed tomography. The sensitivity of lung ultrasonography
in comparison to high-resolution computed tomography was 74.65%, while the specificity
was 68.56%. Conclusion: Lung changes are frequent, but not extensive. Ultrasound A-line
pattern was associated with normal lung parenchyma findings revealed on high-resolution
computed tomography. The negative predictive value for lung ultrasonography (93.2%)
points towards its suitability in return-to-play protocols.

Aim of the study: We present a case report of enlarged cisterna chyli in a
25-year-old woman. The diagnosis was made during a routine abdominal ultrasound
examination and afterwards verified with contrast-enhanced MRI. Case description:
Ultrasound revealed a large, lobulated, anechoic cystic structure with thin, smooth
walls, lacking any solid components. The lesion was located in the retroperitoneal
space, beneath the head of the pancreas, between the partially compressed inferior vena
cava and the aorta, extending almost to the aortic bifurcation. We performed a
contrast-enhanced MRI examination which confirmed the sonographic suspicion of enlarged
cisterna chyli, showing a non-enhancing cystic lesion in continuity with the thoracic
duct. Conclusions: Anatomy, sonographic and magnetic resonance appearance of cisterna
chyli as well as differential diagnosis are discussed.

Authors: Nesen Olena
Published: July 2022

Prerequisites and purpose of education. The COVID-19 pandemic has created unusual conditions for physical education teachers to work with schoolchildren. Children are forced to spend some time at home, which reduces the time for physical activity. The aim of the work is to track changes in the indicators of speed and strength abilities of children aged 12-13 years during the year in the conditions of mixed and distance learning.
Material and methods. Schoolchildren aged 12-13 years took part in the study (Kharkiv, Ukraine; n=31; boys - n=16; girls - n=15). Parental consent was obtained for their children's participation in the study. The following tests were used: “30 meter sprint test, sec.”; “60 meter sprint test, sec.”; “Standing Long Jump Test (Broad Jump), cm”; "Long jump, cm". Assessment of schoolchildren’s speed and strength abilities was conducted at the beginning of the 2020-2021 school year and repeated data – at the beginning of the 2021-2022 school year. The obtained results were analyzed by methods of mathematical statistics: correlation analysis was conducted to identify relationships between the results of control standards of schoolchildren, the reliability of the difference was determined by the Student's criterion.
Results. There is a significant decrease in physical activity of children. Trends to reduce the level of development of speed and strength abilities of schoolchildren for the 2020-2021 school year have been identified. There are high and medium correlations between speed and power tests.
Conclusions. It is recommended to reduce the number of mandatory control standards in the school of choice between: "30 meter sprint test" - "60 meter sprint test"; “Standing Long Jump Test (Broad Jump)” - “Long jump”.
Dynamics of special endurance of athletes aged 13-15 years under the influence of the program of the Cossack duel
Authors: Plokhikh Andrij , Ogar Gennadij
Published: July 2022

Background and Study Aim. National sports are gradually spreading around the world and becoming international. One of such sports is the Cossack duel - a national martial art in Ukraine. In addition to the purely sports component, this sport has national traditions of educating healthy youth. The purpose of the study is to identify the impact of the Cossack duel program on the special endurance of athletes aged 13-15 year.

Material and methods. Athletes (n = 6, age - 13-15 years) of the Cossack duel department of the sports school № 6 (Kharkiv, Ukraine) took part in the study. The children's parents agreed to participate in the study. The study was conducted with athletes of the basic training group on the Cossack duel (sports school №6, Kharkiv, Ukraine) for two years. At the beginning, a preliminary test of the level of special endurance of athletes was conducted. In the end, the final testing of the level of special endurance development of young athletes was conducted. SPSS was used to process the test results. The confidence level is 0.05.

Results. It is established that for two years of using the author's program the density of shock actions of athletes has increased significantly. This is manifested in an increase in the number of blows to the bag with his hands and feet (p˂0.001). It was found that the load of maximum intensity during one round caused significant changes in the cardiovascular system. These indicators were almost indistinguishable (0.7%). The process of restoring heart rate has become more advanced. After 60 sec. recovery difference was 13.2%, and after 120 sec. - 16.1%.

Conclusions. One of the main factors in the training of athletes in the Cossack duel is special endurance. Among the effective methods of improving special endurance are interval and interval-circle training methods. To control the development of special endurance of athletes, it is advisable to use a 1.5 - minute test with the performance of shock actions with hands and feet on a punching bag. Criteria for assessing special endurance should be the intensity of the kicks, heart rate. It is necessary to remember the harmonious upbringing of the individual, to apply health-preserving technologies, to pay great attention to the upbringing of young people in the spirit of respect for national traditions.

Treatment of splenic cysts (SC) in children is variable and controversial. Depending on the size and location of these formations in the spleen, surgical correction is possible in open or laparoscopic surgery, or conservative (non-invasive) management. The result of SC treatment should be the complete elimination of the cyst cavity. Purpose - to evaluate the results of surgical correction or conservative management of CS in children according to remote monitoring changes. Materials and methods. We conducted the study on 265 children aged 0-17 years (mean age 11.25±4.21 years), who were examined and treated for SC. One hundred seventy-five (66.04±2.91%) children underwent surgery, and 90 (33.96±2.91%) patients received conservative treatment. We subjected all the information recorded in the medical records to statistical processing. The mentioned information could characterize the situation with the treatment process and with dynamic monitoring of this pathology to some extent. Results. The most common localizations of cysts were the upper (33.21±2.89%) or middle segments of the spleen (29.81±2.81%). Almost every fourth patient (27.92±2.76%) with SC had pathology of other organs or systems, and every tenth (9.81±1.83%) had other diseases of the spleen. We detected residual cyst in 46.42±3.06% of patients; it underwent complete regression within 1-3 years. Residual cyst of small size (which persisted after surgical correction) regressed much faster after surgery compared with regression of cystic formation of small size in the spleen with conservative management (p<0.05). Conclusions. Therapeutic tactics for SC in children involve different options for individual surgical correction or conservative management, depending on the location, size, relationship to the architecture of the main vessels and the variant of damage to the parenchyma of the spleen. The outcome of treatment of children with SC depends on the volume, location, etiology of the lesion, the method of correction and compliance with all recommendations in the postoperative period against the background of comorbidities. The research was carried out in accordance with the principles of the Helsinki declaration. The study protocol was approved by the Local ethics committee of all participating institutions. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors. Key words: splenic cyst, children, surgical treatment, conservative management, results.

Laparoscopic repair of congenital diaphragmatic hernias can be done in suitable infants and children with good long-term results. The benefits includes lower risk of infection, less intra-abdominal adhesions and early recovery, while being a «scar-less» procedure. Materials and methods. The 3 patients included a 9-months-old infant with a late presentation of Bochdalek left diaphragmatic hernia, and 2 patients with Morgagni congenital diaphragmatic hernia - a 1-year-old infant and a 3-year-old toddler. All procedures were performed in abdominal approach using 3- and 5-mm ports, and a 5-mm 30 degrees camera. Suturing of the diaphragmatic defect was done with unabsorbed materials (Ethibond® 4.0). Results. No intra-operative complications were noted, all patients recovered quickly and uneventfully, and were discharged between 3-6 postoperative day. Follow-up period is now between 3-23 months and so far there is no evidence of recurrence. Conclusions. Laparoscopic surgery is used more and more in smaller cavities by pediatric surgeons. Laparoscopic repair of congenital diaphragmatic hernias in infants and toddlers can safely be performed in peripheral hospitals by skilled pediatric surgeons with good results. However, our follow-up period is relatively short, and because of common recurrence rate in those patients, 15-40% in different reports, both in laparoscopic and open repair, long term follow-up is required. The research was carried out in accordance with the principles of the Helsinki declaration. The informed consent of the patient was obtained for conducting the studies. No conflict of interests was declared by the authors. Key words: children, laparoscopic repair, congenital diaphragmatic hernias.

Considering the relevance of health behaviors for chronic diseases prevalence and mortality and the increase in income concentration observed in the world and in Brazil, this study aimed to evaluate the changes in the prevalence and in the educational inequalities of Brazilian adult health behaviors between 2013 and 2019. We analyzed data of 49,025 and 65,803 adults (18-59 years of age) from the Brazilian National Health Survey (PNS), 2013 and 2019. Prevalence of health behaviors (smoking, alcohol intake, diet, physical activity and sedentarism) were estimated for three educational strata, for both surveys. Prevalence ratios (PR) between year of survey and between educational strata were estimated by Poisson regression models. Significant reductions were found in the prevalence of smoking, physical inactivity, sedentarism, insufficient consumption of fruits, and the excessive consumption of sweetened beverages. However, an increase was observed in alcohol consumption and binge drinking; vegetable consumption remained stable. Contrasting the favorable change in some behaviors, inequalities among schooling strata remained very high in 2019, specially for smoking (PR = 2.82; 95%CI: 2.49-3.20), passive smoking (PR = 2.88; 95%CI: 2.56-3.23) and physical inactivity (PR = 2.02; 95%CI: 1.92-2.13). There was a significant increase in the educational inequality regarding physical inactivity (21%), insufficient intake of fruit (8%) and in the frequent consumption of sweetened beverages (32%). The persistence and enlargement of inequalities highlight the behaviors and social segments that should be special targets for policies and programs focused in promoting healthy lifestyles.
Gênero, ciência e Saúde Coletiva: desconstruindo paradigmas na formação interdisciplinar universitária
Authors: Brandão Elaine Reis
Published: July 2022

Discute-se experiência docente na Saúde Coletiva com estudantes de pós-graduação das Ciências da Saúde, marcadas pelo paradigma biomédico, com contingente feminino. O encontro com novo modo de produzir ciência – situado, relacional, engajado do ponto de vista ético-político e autorreflexivo – promove uma desconstrução epistemológica e abertura para se posicionar como novo sujeito do conhecimento. Mirar o corpo e a saúde-doença como objeto de estudo pela abordagem interseccional conduzem ao deslocamento subjetivo e heurístico da pesquisadora, com suas marcas sociais de gênero, raça, geracionais, nesta empreitada teórica e empírica de (auto)investigação. Encontrar uma questão de pesquisa inclui também se autoencontrar como profissional de Saúde, em sua posição de gênero, classe e raça/etnia. Advoga-se que os estudos sociais da ciência e estudos feministas decoloniais contribuem para que a universidade pública devolva à sociedade profissionais de Saúde que se reconheçam no público que atendem.

Published: July 2022

A literatura endossa o crescente papel central de coordenação do governo federal nas políticas de saúde. Porém, há poucos estudos sobre o papel dos entes subnacionais, em especial, dos estados. Assim, este artigo analisou o arranjo institucional de implementação do Projeto Mais Médicos para o Brasil (PMMB) no estado de Minas Gerais. O trabalho foi realizado com base em análise documental de 31 atas de reuniões da Comissão de Coordenação Estadual e oito entrevistas com atores-chave responsáveis por sua implementação. Os resultados evidenciaram a (i) centralidade decisória do projeto no âmbito federal, a (ii) pouca clareza do papel do governo estadual no arranjo de implementação, a (iii) crise orçamentária do governo mineiro e a (iv) instabilidade política, que resultaram em (v) trocas de governo estadual e federal. Tais fatores, em conjunto, impactaram na capacidade de implementação do projeto em Minas Gerais.

This article is founded on the systematization of Oscar Jara’s experiences to rebuild the paths of Participatory Action Research in Health in rural communities based on experiences of prevention and health care in coping with Covid-19. Since June 2020, we have been developing popular education experiences in rural health guided by Paulo Freire’s pedagogy in northern territories and in the coastal lowlands of the state of Rio de Janeiro, specifically in areas of agrarian reform linked to the Landless Workers Movemen (MST); a quilombola territory; and a women’s collective connected to the Working Group of Women of the Serramar Articulation of Agroecology (GT Mulheres Serramar). The analysis of these experiences points towards pedagogical alternatives produced from academic and popular knowledge, seeking support in popular communication, in the protagonism of rural communities, especially with regard to women as producers of knowledge, care practices and resistance.
Effect of temperature variations on the bond behavior of FRCM applied to masonry
Authors: Ferretti Francesca , Canestri Matteo , Mazzotti Claudio
Published: July 2022

In the last decades, Fiber Reinforced Cementitious Matrix (FRCM) composites were successfully introduced to repair and strengthen existing masonry structures. The good mechanical performances of these materials determined their efficiency as a strengthening technique; however, their durability is still an open issue. As a matter of fact, FRCM composites may be exposed to a combination of different environmental conditions and, additionally, to temperature variations due to solar radiation. The objective of this research was to study the effects of temperature variations on the bond behavior of a FRCM composite, constituted by a basalt grid and a lime-based mortar matrix, applied to masonry. For this purpose, an experimental investigation on thermally conditioned FRCM-strengthened masonry wallets is presented, in which 14 single-lap shear tests were performed. Before testing, samples were exposed to different target temperatures inside a climatic chamber: 32, 40, 50, 60 and 80 °C. Thermocouples were embedded within the FRCM reinforcing layers at two different depths to detect the inner temperature profiles and to control the conditioning process. The single-lap shear tests were then carried out inside the same climatic chamber, while maintaining the target temperature constant. A decrease in terms of peak-axial stress was observed by increasing temperature, along with a progressive change in the failure mode, from fiber rupture outside the bonded area to fiber slippage within the mortar matrix layers.

Los procesos migratorios cada vez más generan nuevas dinámicas económicas y sociales. Una de estas di-námicas es el emprendimiento migratorio. Este artículo busca entender los procesos, el perfil y la relación con el entorno de los empresarios migrantes en el sector de la comercialización de productos étnicos o especia-lizados de sus países de origen en París, Francia. Se encontró que elementos como la elaboración de análisis financieros, de riesgo y de marketing no son realizados por la mayoría de los empresarios, aumentando el riesgo de quiebra. Sin embargo, con el aumento de consumidores franceses, el empleo de migrantes en este tipo de empresas genera una mayor obligación de adaptación del personal extranjero para comunicarse con sus clientes potenciales.
El Aprendizaje Basado en Proyectos como metodología incluyente: Apropiación del inglés como segunda lengua a través de esquemas de intervención social

Published: July 2022

El objetivo de este artículo es destacar el impacto académico y emocional que expone el uso del Aprendizaje Basado en Proyectos en el proceso de aprehensión del inglés como segunda lengua. Lo que se devela es el resultado de una intervención pedagógica que pretendía contribuir a través de la estructuración de una guía instruccional, las fases organizativas para el desarrollo de un proyecto tipo III con base en el método de proyectos de William Kilpatrick (1918). La metodología planteada, es un estudio explicativo secuencial desarrollado por medio de un enfoque mixto, el cual, constituyó el análisis del diseño de un esquema social en pro de la aceptación de las diferencias haciendo uso del inglés como código lingüístico. Como resultado del análisis se manifiesta efectividad en la apropiación del idioma al establecer espacios investigativos que involucren los intereses, las realidades sociales y las afecciones tangibles de los aprendices; puesto que, estos factores de correlación se constituyen como elemento clave de integración e interacción común en los grupos de investigación. Se concluye que, el uso del ABPr fortalece el proceso de apropiación del inglés como segunda lengua, no obstante, los elementos emocionales componen un factor imprescindible durante el ascenso académico, especialmente en los primeros grados de escolaridad; por ende, es indispensable ofrecer un ambiente de seguridad, respeto y formación según las necesidades educativas de los estudiantes.

De acuerdo con el Centro Nacional de Memoria Histórica (CNMH), el departamento del Meta es uno de los más golpeados por la violencia en Colombia, por esta razón es un lugar propicio para el estudio del conflicto armado colombiano. La investigación que presenta este libro hace una aproximación multidisciplinar al conflicto armado colombiano, a la vez que presenta una estrategia de generación de valor social y económico Se apoya en la propuesta de un nuevo paradigma que intenta comprender a quienes han crecido en medio del conflicto armado desde el individuo mismo, que se construye al integrar las bases teóricas de la biopolítica, la resiliencia y la responsabilidad social como elementos necesarios para enfrentar los desafíos de incorporar en el individuo una cultura de respeto, en la que no sea necesario recurrir a la violencia para sobrevivir. En consecuencia, y ante una historia de violencia que ha penetrado más de tres generaciones, perpetuado el conflicto social y armado e impactado de manera directa e indirecta a la población; se presenta la oportunidad de contribuir con la comprensión de lo que ha sido el conflicto armado colombiano desde la perspectiva de sus actores y abrir el camino para que la población pueda alcanzar la anhelada paz. Para esto fue necesario la construcción y desarrollo de un proyecto de investigación que, con un enfoque holístico, explora la percepción que los actores del conflicto representados por las voces de exmilitares, excombatientes de grupos al margen de la ley, desplazados, víctimas y habitantes de la región, que quisieron contribuir al cambio, compartiendo sus historias de vida basados en los temas propuestos en entrevista semiestructurada. Este libro es el resultado del análisis exhaustivo de las historias y relatos que compartieron los diferentes actores del conflicto y que permiten abrir el camino hacia la discusión teórica necesaria para consolidar una nueva forma de entender al individuo que ha crecido en medio del conflicto armado. Esto con el fin de contribuir con la construcción de un nuevo valor social que permita edificar un escenario de respeto y convivencia pacífica.
Facing the Music through Environmental Administrative Penalties: Lessons to be Learned from the Implementation and Impact of Section 24G?
Authors: Hall Jenny
Published: July 2022

Section 24G was inserted into the National Environmental Management Act 107 of 1998 to provide a mechanism for authorising activities that commence unlawfully. It contains South Africa's only environmental administrative fine - and a quasi one at that. The section has spawned much debate and controversy, including the fact that its existence and purported abuse undermine the fundamental objectives of environmental impact assessments - a cornerstone of government's legislative and decision-making response to the environmental right. This article presents certain results of the first part of an empirical study which explored the criticisms of section 24G; the extent to which it has a deterrent effect, and the lessons that can be learned in designing an administrative penalty system. Approximately 400 people, including representatives from government, the regulated community and environmental consultants were interviewed or surveyed. The results yielded several observations. This article focuses on the extent to which the section is used and the degree of awareness and knowledge about section 24G. The second part of the study probes the deterrent effect of section 24G in more depth by considering the influence that experience – either own or other's – has had on the regulated community.

The effect of marine microalgae metabolites on pathogenic bacteria biofilm-formation on polystyrene was estimated in the paper. Experiments revealed that extracellular compounds Prorocentrum foraminosum PrRUS_7 and Heterosigma akashiwo HAK-SR11 inhibit bacterial growth on polystyrene surfaces. It was also found that Alexandrium affine metabolites stimulated the biofilms development in several cases. By means of scanning electron microscopy it was possible to visualize the effects of inhibition and stimula-tion of pathogen growth manifested by microalgae metabolites. The obtained data can be used for further research in order to create disinfectants for polystyrene materials processing in food production.

Brown alga Fucus distichus is one of the widespread, eurybiont species and is a promising object for commercial and sanitary mariculture. This determines the interest in studying its development under different growing condi-tions. In this paper, we discuss the morphogenetic development of F. distichus labeled samples in different areas of the Avacha Bay: Zavoiko Bay and Seroglazka Bay, from May to August. The bays differ significantly in the level of anthropogenic pollution and hydrodynamic load and, to a lesser extent, in the temperature regime and pH level of coastal waters. During observations, which began in May and ended in August, the total height and length of branches of different orders were measured and the state of fertility was determined in the studied samples. During the research period, the morphometric processing of labeled samples was carried out 4 times in Zavoiko Bay and 6 times – in Seroglazka Bay. The study results showed that anthropogenic pollution has the greatest im-pact on the development of the studied species. In Seroglazka Bay, where the berths of 2 large fishing enterprises are located and also household and industrial discharge from 12 city sewers occurs, F. distichus formed only 3 dichotomous branches from May 29 to August 12, and the fertility stage was absent. In Zavoiko Bay, which is widely open to tidal currents and does not have sewage discharge, F. distichus formed 6 dichotomous branches and all the terminal branches were at different stages of fertility. Based on the obtained data, we concluded that Fucus can be used for biomonitoring of the ecological state in the coastal areas.

The emulsifying ability of pumpkin seed flour determines the range of its application in food technology. Identification of varietal characteristics of pumpkin seed flour proteins raises the efficiency of its use. The pumpkin seed flour of the four most common and different in ripening period kinds was selected for study, such as Kroshka, Vitaminnaya, Mozoleevskaya and Golosemennaya. The protein composition of the seed flour of the selected pumpkin varieties was evaluated by such indicators as the mass fraction of pro-teins, the distribution of proteins into individual fractions and their polypeptide composition. Pumpkin seed flour Golosemennaya contains albumins and globulins most of all, it has the most active low- and high-molecular polypeptides and the best ability to form emulsions.

The validity of the allocation of the Commander ornithogeographic district on the zoogeographic map of Kam-chatka has been confirmed. This diagnosis is relevant, despite some doubts among taxonomists about the inde-pendence of individual endemic Commander subspecies of birds. The similarity of the nesting and probably nest-ing bird fauna of Kamchatka, the Commander and Aleutian Islands was estimated using the Jacquard formula [Pesenko, 1982] based on the revision results of the avifaunistic lists of these regions. The opinion that the avifau-na of the Commander Islands is related to the Aleutian one was confirmed. The similarity index between the avi-fauna of the Commander and Aleutian Islands is greater (38.1%) than between the Commander Islands and Kam-chatka (24.7%), despite the fact that Kamchatka is much closer to the Commander Islands. The Commander avifauna meets the most important criteria of island faunas, such as impoverishment and subspecific endemism. In addition, the representatives of archaic forms lived on the Commander Islands not so long ago, which disap-peared primarily due to human extermination. The current state of most Commander endemic bird subspecies is quite stable. American mountain finch may show some tendency to decline.

The official statistics data of domestic catches do not allow to form appropriate estimate about the actual state of stocks and population dynamics of Russian Pacific salmon in the 20th – early 21st centuries, because a significant fishing load was provided by Japanese fishermen for a long time. During this period the stocks were on the rise twice (from 1929 till 1960 and from 2004 till present time) and once they were in a depressed state (1961–2003). Apparently, the maximum abundance values during the rise periods were approximately at the same level. The duration of high and low abundance periods is approximately similar. The full cycle of changes in was 65–75 years. The current period of the Russian Pacific salmon high abundance, according to the rhythm of previous periods, may last until the early 2030s. The minimum recorded catches during this period of time will be at least 250 thousand tons and the maximum will be in the range of 500–600 thousand tons.
