Published: July 2022

Educational institutions are required to prepare competent and competitive pre-service teacher graduates who have skills according to the needs of the 21st century. This study aims to find the effect of blended Project-Based Learning (PjBL) integrated with 21st-century skills on higher-order thinking skills of students as pre-service biology teachers on immunology. This research is an experimental study with a mixed method, in which the qualitative observation data used a questionnaire with self-assessment and peer assessment methods supported by experimental data using the HOTS instrument analyzed quantitatively. The application of blended PjBL integrated with 21st-century skills used a quasi-experimental research method with a quantitative descriptive approach. Pre-service teachers in this study are still studying at educational institutions, especially teacher faculty, and categorized as pre-service teachers. The research sample was students taking the immunology course in the Biology Education Study Program. They were 57 students from IAIN Palangka Raya, 60 students from Universitas Palangka Raya, and 83 students from Universitas Negeri Malang. Student grouping based on the initial ability of HOTS is carried out in all groups from which the student sample is referred to as a cluster. The total sample of 200 people was then grouped into three groups based on their basic abilities, namely low-level class, medium-level class, and high-level class. The study results proved that the blended PjBL integrated with 21st-century skills significantly affected students' high-level thinking skills based on the paired sample test (Sig. 2-tailed 0.0000.05). The mean value in the experimental group (75.53) and the control group (56.35) strengthens the data significance of students' higher-order thinking skills based on the N-Gain value and the independent sample T-test. The findings of this study are that blended PjBL integrated with 21st-century skills can increase HOTS on indicators of evaluating (78.15) and creating (79.21). This blended learning integration can be used as an innovative learning model solution to increase pre-service biology teachers' higher-order thinking skills according to the demands of 21st-century skills.

Published: July 2022

The use of chlorine in agriculture and settlements increases and impacts surrounding waters, such as watersheds:  The land area is a unit with rivers and tributaries that function to accommodate, store and distribute water from rainfall to the sea naturally.  The environmental condition of the Tondano watershed is important to study in terms of chlorine distribution, considering that residential and agricultural activities in the watershed can cause residues in the aquatic environment, which harm the environment, especially phytoplankton. This study aims to examine the concentration of chlorine and its impact on the phytoplankton diversity in the Tondano watershed, North Sulawesi, Indonesia. Using the composite method, water quality sampling to calculate chlorine concentration was carried out at 17 river locations using the composite method, while six river stations represented phytoplankton sampling. Chlorine concentration was measured using UV-VIS spectrophotometry, while plankton sampling used a plankton net with a mesh size of 40 µm and a net mouth diameter of 20 cm. The results show that the highest chlorine concentration was found in Tondano Hilir River (0.05 mg/L), followed by the Kakas River downstream (0.04 mg/L). Chlorine concentration distribution in other rivers has the same concentration (0.03 mg/L).  Quality standard Chlorine according to Government Regulation number 22/2021 Appendix VI Class II is 0,03 mg/L. The highest number of species and index of phytoplankton species diversity was found in the Hulu Panasen River, while the highest species abundance was found in the Tondano River downstream. The correlation analysis of species diversity index with chlorine concentration did not show a significant relationship with the diversity of phytoplankton, but aquatic ecosystems have experienced moderate ecological pressure.

Authors: Irwanto I. , Redhana I. W. , Wahono B.
Published: July 2022

Understanding pre-service teachers’ perceived technological pedagogical content knowledge (TPACK) is important to better prepare them for their future STEM-related careers. Thus, this study aims to examine pre-service teachers’ perceptions of TPACK in relation to their age, gender, and grade level. To achieve this goal, a cross-sectional survey design was used in this quantitative non-experimental research. Participants included 481 (136 male; 345 female) pre-service teachers from four public and private universities in Indonesia. A 27-item PTTPACK Survey was used to gather data. Independent t-test, ANOVA, and Person’s correlation were executed to analyze the data. The findings suggested that pre-service teachers performed the highest self-confidence level in pedagogy knowledge and the lowest in technology knowledge. They rated themselves above four on a five-point scale. No significant differences for all TPACK dimensions were found in terms of gender and age. In addition, there was a significant difference between pre-service teachers who were at the postgraduate level and those at the undergraduate level. Moreover, a high positive and significant correlation existed between all six TPACK domains. It is suggested that pre-service teacher preparation programs should facilitate pre-service STEM teachers how to integrate pedagogy, content, and technology together to create effective technology-enhanced learning in their subjects.

Published: July 2022

Guided inquiry learning has improved scientific literacy skills in various studies. This fact, however, contradicts new findings from the 2015 PISA survey. The research aims to assess inquiry-based OE3C learning methodologies that incorporate local socioscientific issues (SSI) to improve students’ scientific literacy. The research method used quantitative and qualitative methods to evaluate the planned strategy for teaching thermochemistry and rate reactions. The local SSI-based OE3C was used in a sixteen 90-minute lesson with 72 eleventh-grade students (experimental group) at an Indonesian public high school. A control group of 68 students from the same school was taught using guided inquiry learning. The experimental group received a 17-item questionnaire on students’ opinions of the instructional process using the OE3C based on local SSI and a 24-item scientific literacy test (Cronbach alpha = 0.717) from pretest and posttest. The control group also received the scientific literacy tests from pretest and posttest. The finding shows that OE3C learning based on SSI effectively enhances students’ scientific literacy skills. These findings are consistent with the results of the student perception questionnaire, which are supported by semi-structured interview findings 7.78% of students are highly pleased to learn using local SSI-based OE3C learning, and 95.83% of students think that learning to use local SSI-based OE3C learning steps helps them gain a better knowledge of the material. The findings of this study suggest that local SSI should be integrated into chemistry classes to help students build scientific literacy skills.

This study aims to measure the effectiveness of using ethnochemistry-based Adobe Flash learning media using indigenous knowledge on scientific literacy. The study used a quasi-experimental method. The research subjects were 68 students who used ethnochemistry-based Adobe Flash learning media using indigenous knowledge on secondary metabolite material. The research is a quantitative study with pretest and posttest design. Data in the study were collected through tests to determine students' scientific literacy skills, including aspects of knowledge and competence in analyzing scientific phenomena, connecting chemical concepts to existing phenomena, and interpreting data or scientific evidence and questionnaires. Supporting data was obtained through a questionnaire to determine learning media users' opinions. The test was conducted with ten multiple-choice questions and a questionnaire with ten statements using a Likert scale of 1-4. The data analysis technique calculates the average score of test questions that have criteria according to scientific literacy and the percentage of user satisfaction. Based on the research results, the average value of 81.50 for scientific literacy skills on the concept of secondary metabolites with an N Gain of 80% is in a good category, and it is also known that the average percentage of user satisfaction is 83%, in a good category. Based on the hypothesis testing using the right-test, it has a t count of 16,160 and a t table of 2,021. The study concludes that applying ethnochemistry-based Adobe Flash learning media on secondary metabolites is effective for students' scientific literacy. Thus, it could be excluded that interactive media can support students' learning and improve scientific literacy.
Students’ Knowledge and Attitudes toward Science: Its Correlation on Students’ Disbelief in Non-Scientific Misinformation
Authors: Rofieq A. , Fauzi A.
Published: July 2022

Immense students’ belief in misinformation indicates the less optimized quality of science education. However, research that analyzes the predictors of this problem is still rarely done. Biology knowledge (BK) depicts the level of biological information mastered by students; attitude toward science (ATS) is related to students' views when participating in science learning; while disbelief in conspiracy theories (DiCT) describes a person's ability to examine information that contradicts scientific truth. The current research was aimed at analyzing BK, ATS, and DiCT among Biology students, as well as the correlation between the three. The data collection instrument used was an online questionnaire comprising four main sections: demographic items, 15 Biology, and the General Public Questionnaire items, 40 ATS test items, and 8 DiCT items. Analysis was conducted on data from 820 respondents collected from February-March 2022. Some techniques for data analysis were applied, including frequency and percentage estimation, Kruskal-Wallis H test analysis, Dunn's test analysis, Kendall's Tau Correlation, and rank-based estimation regression. This research found that: 1) student’s ages and genders did not significantly contribute to any, while institutional status and study years did to BK and DiCT; 2) study program significantly contributed to ATS, and 3) ATS was found to not correlate significantly with DiCT, but BK was significant by the DiCT. Therefore, BK becomes the main competency that can protect students from unscientific conspiracy theories. This study has revealed a novelty framework about the position of knowledge and attitude in predicting students' abilities when examining misinformation.

Published: July 2022

A 47-year-old previously healthy man was referred to a local hospital with chest tightness, oliguria, and lower extremity edema for seven days. An initial investigation revealed acute heart failure and kidney injury. The patient was intensively treated with cardiac and renal replacement therapy, and cardiorenal function improved one week later. Two months later, echocardiography was performed because chest tightness and edema had not resolved. Echocardiography showed Valsalva sinus rupture, and the patient was transferred to our center. Myocardial calcification was observed in the left ventricular wall on computed tomography after admission. The patient underwent cardiac surgery and recovered smoothly. At the three-year follow up, the patient was asymptomatic with normal renal function and serum electrolytes. Imaging revealed a significant reduction in diffuse calcification of the left ventricular wall. This case indicates that this rare form of reversible myocardial calcification may be associated with acute heart and renal failure caused by Valsalva sinus rupture. The results of this case will guide clinicians about further management and timely referral of such patients to appropriate specialties.

Published: July 2022

Objectives: To explore the personalized treatment strategy of sternal fixation and closure of sternal median incision in open cardiac surgery.
Methods: A total of 293 patients who underwent open-heart surgery with a median sternal incision at Peking Union Medical College Hospital from January 2019 to March 2021 were divided into two groups, according to the timing and type of treatment. The first 169 patients received single-wire fixation and closure (control group), while the subsequent 124 patients received double-wire fixation and closure (study group). The patients were followed up for three months to observe the duration of pain, sternal instability, and occurrence of chest wound infection.
Results: The average age was 53±30 years in the control group and 55±34 years in the study group (P = 0.594). There were no significant differences in baseline data between the two groups (P > 0.05). Compared with the control group, the study group had a shorter duration of pain (P < 0.05), smaller drainage volume within three days postoperatively (650 ml vs. 770 ml, P < 0.05), lower incidence of superficial sternal wound infection (2.4% vs. 8.9%, P = 0.042), and lower incidence of sternal instability (1.6% vs. 8.3%, P = 0.026). Deep sternal wound infection occurred in two patients in the control group and none in the study group; however, this difference was not significant. No surgery-related deaths occurred.
Conclusions: Selecting the appropriate sternal fixation and closure method, according to the characteristics of patients, can reduce the incidence of sternal incision complications. We proposed a personalized selection strategy for sternal fixation and closure, which requires verification in clinical studies.

Published: July 2022

Background: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a significant and severe complication that affects morbidity and mortality. We studied both pediatric and adult patients using the Acute Kidney Injury Network (AKIN) definition.
Methods: This was an observational retrospective cohort study done at King Abdulaziz University Hospital in Jeddah, Saudi Arabia, and approved by the ethical committee. The exclusion criteria were baseline serum creatinine (SCr) ≥ 4 mg/dL or preexisting renal failure requiring dialysis, reoperation, death within 24 hours postoperatively, and operative mortality or missing data. We included 941 patients in the analysis using statistical software SPSS, version 15.0.
Results: Of the total number of patients, 28.68% in the adult group and 20.07% in the pediatric group developed CSA-AKI. Adult risk factors included the age group 60-69 years, cardiopulmonary bypass (CPB), number of grafts, and hypertension. In the pediatric group, CPB, aortic cross-clamping (ACX), and the lower preoperative SCr were the main risk factors
Conclusion: Conventional conservative management and preoperative identification of predictor risk factors are essential for preventing CSA-AKI, constituting the primary strategy for optimal management.

Meme e ideología: Una mirada alternativa de análisis
Authors: Sánchez-Araya Alejandro
Published: July 2022

This article focuses on a proposal for an alternative analysis of the meme, by transcending from “content” to “form”, based on the Evocation Model of Lee Wood, Stoltz, Van Ness and Taylor (2018) and the analytical theoretical perspective of the “Ideology” developed by Žižek (2003). Its purpose is to show that this type of cultural objects are made up of several layers, from which alternative readings can be generated. Through the methodological structure based on the social construction of meaning, the elements of the memes that work (from the žižekiana theory) will be identified as those symptoms that prevent the achievement of different ideological fantasies, based on the establishment of a common power pattern of character racialized. In this way, emphasis is placed on the reasons why the meme should be treated as a new cultural product governed by different visual codes and relationships whose interpellative capacity can be analyzed from its “form”.
La pedagogía de la alteridad en la deconstrucción de la xenofobia y la construcción del nos-otros: Una mirada desde la percepción de las personas docentes de Educación Cívica de la Dirección Regional de San José Oeste
Authors: Chinchilla Fallas Susana María , Vindas Gómez Bryan
Published: July 2022

The purpose of this document is to articulate different processes that intervened in the final graduation work of the Licenciatura of Social Studies and Civic Education Teaching. From a theoretical point of view, an analysis is carried out based on concepts such as xenophobia, interculturality, Civic Education and Pedagogy of Otherness. These concepts are fundamental for the methodological section where each of the stages implies the development of the proposed objectives: the documentary analysis, interviews with teachers and administrators and teacher training workshop on the pedagogy of otherness. From the pedagogy of otherness, the deconstruction of practices that tarnish adequate human coexistence, such as xenophobia, is advocated for the construction of a pedagogy of Nos-Others, where, based on empathy and otherness, the understanding of the other and their contributions is sought in the construction of a just and democratic society.

Published: July 2022

BACKGROUND AND OBJECTIVES

We evaluated the economic impact of routine childhood immunization in the United States, reflecting updated vaccine recommendations and recent data on epidemiology and coverage rates.

METHODS

An economic model followed the 2017 US birth cohort from birth through death; impact was modeled via a decision tree for each of the vaccines recommended for children by the Advisory Committee on Immunization Practices as of 2017 (with annual influenza vaccine considered in scenario analysis). Using information on historic prevaccine and vaccine-era incidence and disease costs, we calculated disease cases, deaths, disease-related healthcare costs, and productivity losses without and with vaccination, as well as vaccination program costs. We estimated cases and deaths averted because of vaccination, life-years and quality-adjusted life-years gained because of vaccination, incremental costs (2019 US dollars), and the overall benefit-cost ratio (BCR) of routine childhood immunization from the societal and healthcare payer perspectives.

RESULTS

Over the cohort’s lifetime, routine childhood immunization prevented over 17 million cases of disease and 31 000 deaths; 853 000 life years and 892 000 quality-adjusted life-years were gained. Estimated vaccination costs ($8.5 billion) were fully offset by the $63.6 billion disease-related averted costs. Routine childhood immunization was associated with $55.1 billion (BCR of 7.5) and $13.7 billion (BCR of 2.8) in averted costs from a societal and healthcare payer perspective, respectively.

CONCLUSIONS

In addition to preventing unnecessary morbidity and mortality, routine childhood immunization is cost-saving. Continued maintenance of high vaccination coverage is necessary to ensure sustained clinical and economic benefits of the vaccination program.
Mass poisonings of the Vulnerable Andean condor prompt national strategy against the use of toxic baits in Argentina

Published: July 2022

Massive deaths of Andean condors (Vultur gryphus) prompted a National Strategy Against the Use of Toxic Baits in Argentina, based on 6 lines of action: 1) delivery of kits and uniﬁed intervention protocols in cases of wildlife poisoning, 2) community education programs, 3) surveys of rural people, 4) training courses and participatory construction workshops, 5) toxicology studies, and 6) an academic-scientiﬁc committee made up of specialists in toxicology. The strategy was developed in the 14 provinces of the country where the Andean condor is distributed. 554 people from 166 institutions have participated in the trainings and workshops, reporting 200 poisoning events involving more than 21000 individuals from 61 species. Birds and mammals were the groups most aﬀected, and further, human victims show the impact on public health. 19 toxic substances were identiﬁed, mainly insecticides. This study proved that carbofuran is the toxic most used. Analysis of bait types suggests a signiﬁcant conﬂict with carnivores. 195 surveys revealed that almost half of the farmers know people who use toxic baits and that the negative perception towards some species could determine their use. The strategy began to address the problem of the use of toxic baits in Argentina in a strategic, participatory and regional way, through the management of public policies and scientiﬁc research. We propose actions to work on the causes that lead to the application of this dangerous practice. Given its extensive use, we believe that this strategy can be adapted and applied in other countries in the region.
Empatía y arquitectura: una propuesta fenomenológica.
Authors: Fuentes Farías Francisco Javier
Published: July 2022

Un problema poco examinado en las teorías del diseño es la naturaleza de las experiencias emocionales que despierta el espacio edificado, por ejemplo, los sentimientos de atracción o rechazo en determinados lugares, el sentimiento de pertenencia o de solemnidad y de trascendencia ante ciertas formas urbanas, edificaciones o espacios públicos, tales como iglesias, cementerios o jardines y plazas. En este trabajo se plantea que para saber cómo influye la arquitectura en las emociones de los habitantes, el especialista endiseño urbano-arquitectónico debe explorar sus propias experiencias ante el espacio arquitectónico y ante laesfera social y emocional que forma parte de este. Para demostrarlo se abordó brevemente el concepto deempatía, la cognición social, y la interacción social a partir de una revisión bibliográfica de recientes publicaciones de diseño urbano-arquitectónico. Se comparó la base teórico-metodológica y epistémica del diseño con otras provenientes de la geografía cultural, de los estudios urbanos y culturales y de las ciencias cognitivas en su vertiente corporeizada, así como de la tradición hermenéutica sobre la interpretación de significados. Como casos de estudio se tomaron algunos ejemplos de proyectos constructivos que dan preponderancia a la interacción simbólica, a la percepción fenoménica, y al manejo colectivo de significados y metáforas cognitivas. Si bien la actividad cerebral coordina la cognición social y diversos estados emocionales, el contexto urbano-social también determina el significado de las emociones y experiencias sensibles en una producción colectiva de sentido mediante la inter-corporalidad y la interacción.

Published: July 2022

El proceso de financiarización ha permitido la reproducción de capital mediante la extracción de rentas a partir de la generación de instrumentos financieros. Uno de ellos, que ha tenido creciente importancia en la última década en México, es el caso de los Fideicomisos de Inversión en Bienes Raíces (FIBRAS), los cuales han dinamizado al sector inmobiliario. Con base en la revisión de los reportes a accionistas emitidos por estos fideicomisos y por la Bolsa Mexicana de Valores (BMV), analizamos la forma en la cual estos mecanismos financieros han permitido la construcción de grandes proyectos inmobiliarios en zonas que podrían considerarse no apropiadas por condiciones de rentas urbanas. Mediante el análisis del centro comercial "Parque Las Antenas" gestionado por FIBRA Danhos en la Ciudad de México, discutimos las problemáticas que se han generado en el territorio en donde se han constituido.

En el ámbito latinoamericano, este proceso ha estado marcado por el predominio de la autoconstrucción y de desarrollos informales bajo distintos modelos; entre ellos el de Producción Social del Hábitat. En España, dicho crecimiento se ha manifestado a partir de procesos de dispersión urbana con la particularidad de haber acogido, junto a desarrollos planificados, otros realizados al margen del planeamiento. Asociados a estos, las urbanizaciones ilegales tuvieron una especial incidencia en la década de los setenta y ochenta del siglo pasado. En este contexto, el objetivo del artículo es establecer un análisis de dos formas de producción de ciudad que, aunque se manifiestan en contextos espaciales y socioeconómicos diferentes, presentan ciertos elementos comunes. Metodológicamente, la investigación se plantea desde una doble perspectiva; de carácter teórico, a partir del análisis de fuentes secundarias poniendo en diálogo dos tradiciones conceptuales de procesos similares en regiones distintas. Y la segunda, de tipo empírico, centrada en el estudio del alcance espacial de las urbanizaciones ilegales en España. Los resultados apuntan a que estas mantienen una importante presencia en las periferias de las principales ciudades del país. Y, en segundo término, que los cambios de modelo lo han convertido en un modo de producción del  espacio desarrollado al margen de los canales oficiales y, en cierto sentido, no alienado por el Estado, rasgos que lo aproximan a la Producción Social del Hábitat.

Subtotal resection of the colon in intestinal agangliosis depends on the level of lesion and secondary decompensatory changes in the intestinal wall. Rational choice of reconstructive plastic surgery in such pathology is necessary to restore patency, normalize functional changes in the intestine and stabilize the general condition of patients. Purpose - to evaluate the results of reconstructive-plastic surgery to restore patency at different levels of subtotal resection of the colon in children with intestinal agangliosis. Materials and methods. We analyzed the surgical treatment of 182 children with intestinal agangliosis aged from 1 month to 8 years, who underwent reconstructive-plastic surgery to restore patency at different levels of subtotal resection of the colon. Results. In 58 (31.86%) patients after subtotal resection of the colon performed the pullthrough of the remaining segment of the colon on the left mesenteric sinus (lateral canal), in 51 (28.02%) - pullthrough of the remaining segment of the colon on the right mesenteric sinus in front of the terminal ileum, in 63 (34.62%) - pullthrough of the ascending colon or caecum on the right flank with a rotation of 180° and in 10 (5.50%) children - replacement of the left half of the colon with an ileograft with intrarectal pullthrough. In 161 (88.46%) cases good results were obtained, and in 21 (11.54%) patients - satisfactory functional results in the long term follow up. Conclusions. Restoration of intestinal patency after subtotal resection of the colon in children with intestinal agangliosis should be aimed at providing favorable conditions for anastomosis between the remaining part of the colon and rectum. If it is impossible to directly anastomose the remaining segments of the colon and rectum, it is advisable to replace the left half of the colon with an ileograft with its intrarectal pullthrough. Differential approach in the choice of reconstructive plastic surgery for subtotal resection of the colon allows to normalize functional changes in the intestine and stabilize the general condition of patients. 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 interest was declared by the authors.

Thymolipoma is a rare benign encapsulated tumor of anterior mediastinum. Overall, thymic neoplasms comprise only 4% of all mediastinal tumors. Only 2–9% of these are reported to be thymolipomas. Less than 200 cases have been published in the world literature and its incidence in both genders is equal and usually develops at any age. The youngest case in the literature was described in 6-month-old child. Thymolipoma can be associated with chronic lymphocytic leukemia, myasthenia graves, aplastic anemia, hyperthyroidism and Hodgkin’s disease. Half of the patients are asymptomatic, the neoplasm incidentally is discovered radiologically. The other half mostly represents shortness of breath, cough, chest pain and upper respiratory tract infection. The clinical case, diagnosis and treatment of gigantic thymolipoma in 3-year-old child is described in this article. A clinical case of giant thymolipoma in a 3-year-old child is presented. The child had several respiratory symptoms: episodes of choking, dry cough, groaning breathing during physical exertion and anxiety, chest deformity (enlarging the right half) and signs of type II respiratory failure. Radiographically - subtotal darkening of the right hemithorax with mediastinal shift to the contralateral side with compression of the left lung; laboratory results - hyperleukocytosis(39х109/l). Computed tomography showed a large hypovascular mass formation with inhomogeneous structure and areas of lipomatosis. Most likely, this is the case of congenital nature of thymolipoma, which manifested itself at the age of 3. Correct pathomorphological diagnosis was made with the help of open biopsy, since when performing the puncture method, there is a possibility of verification error due to insufficient amount of histological material given the inhomogeneity of the mass of the formation, as well as taking into account the suspicion of a lymphoproliferative process. Considering the mediastinal and intrathoracic compression syndrome, as well as the benign nature of these tumor, which is characterized by the absence of infiltrative growth, the only correct treatment tactic is radical surgery. 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 interest was declared by the authors. Key words: neoplasms of anterior mediastinum, thymolipoma, children.
Understanding the Dynamics of the Prices of Natural Gas as an Important Step in Energy Transition
Authors: Bech-Wysocka Katarzyna
Published: July 2022

Objectives: The natural gas seems to be an attractive supplement to the renewable energy sources in energy transition towards low carbon emissions. Given its flexibility to transmit and store, the natural gas offers a diversity of the renewables. Understanding the formation of natural gas prices is crucial for evaluating the costs of energy transition, in particular the return to investment into natural gas infrastructure.
Research Design & Methods: In order to study the natural gas prices dynamics in Poland, I developed a Vector ErrorCorrection model (VECM) for a joint determination with prices in the USA and in Europe. The VECM setup made it possible to analyse the interactions among non-stationary prices as well as investigate how disturbances specific to the discussed markets pass on within the system.
Findings: By exploring impulse response functions and forecast error variance decompositions, I demonstrate that the European natural gas prices are not affected by shocks in the American gas market, as they are determined solely by the shocks specific to the European natural gas market. Additionally, the natural gas prices in Poland are highly correlatedwith, and responsive to, other European countries’ prices. The results go in line with the hypothesis of the existence of a common, integrated European natural gas market.
Implications / Recommendations: In the context of energy transition, the return to investment within natural gas infrastructure can only be forecast given the predicted prices. The appropriate proportion of alternative energy sources in the energy mix can be achieved only after examining this dynamics and the differences in prices of alternative energycommodities. Hence, the feasibility of predicting natural gas prices should always be considered at the early stages of any energy transition policy.
Contribution / Value Added: The results add to the discussion on the role of natural gas in energy transition. They revealhow gas prices on the main markets have fluctuated over the recent years as well as they link the prices in Poland to natural gas prices abroad. The findings fill the gap in the literature, which so far has been focused mainly in the Americanmarket.

ABSTRACT Objective: To analyze the evidence available in the literature on the use of essential oils for healing and/or preventing infection in surgical wounds. Method: Systematic review according to the JBI model and PRISMA statement. The search was carried out in November/2020 and updated in December/2021, using descriptors and keywords, in the CINAHL, LILACS, CENTRAL, EMBASE, PUBMED, Scopus, and Web of Science databases. The quality of the evidence was assessed using the JBI critical appraisal tool for randomized controlled trials. Results: Five publications were included. Three studies evaluated healing and the presence of infection after episiotomy using the Redness-Edema-Ecchymosis-Discharge-Approximation (REEDA) scale; one study evaluated healing after periodontal surgery using the plaque index and Modified Gingival Index; the other four studies considered the presence of infection after episiotomy. Most studies used lavender oil, associated or not with other oils (80%). Two studies showed an improvement in healing. The infection outcome, although mentioned by 60% of studies, was not assessed as a primary outcome. Conclusion: The promising efficacy of essential oils, especially lavender, was verified in the healing of surgical wounds, especially in episiotomies.
