Authors: Thompson Elizabeth , Thompson Ross , Bartle David
Published: January 2022

Safe training in the current clinical workplace requires careful participant proximity management. Delivering simulation in a confined clinical environment can impact scenario fidelity and affect psychological safety

The aim of the study was to assess the practical efficacy of a portable AV streaming solution to enable real-time

The Scotia Medical Observation and Training System (smots™) offers a portable AV solution with flexibility, through the addition of cameras and microphones as required, to create bespoke simulation viewing. Smots™ was incorporated into the

Smots™ was an effective platform to meet our aims. Delivery users reported smots™ to be reliable in streaming the AV footage to a target audience in a remote debriefing room. The system was compact, easily transportable and had a low burden of training to achieve user competence. Participant feedback was positive, in that the system provided good AV clarity and narration, thereby enabling a successful training evolution. Smots™ offers a reliable capability to stream simulation scenarios to an alternative viewing area with the ability to be relocated as needed. Local wireless broadcasting range is finite and may limit users’ ability to stream information to discrete departments within a larger trust. Mitigation is possible using a secondary streaming platform or integrating it into a secure internal Wi-Fi or ethernet network. Assistance from trust information technology departments is recommended and this capability is something our team will consider as a future option. Expanding connectivity is an effect multiplier, offering distanced, streamed training across trusts and regions, as well as the inclusion of participants working from home. The portable nature of this smots™ solution offers flexibility for rapid deployment to areas of novel clinical capability and community partnerships. This system has proved exceptionally useful during a prolonged period of social distancing, enabling ongoing high-efficacy
29 Reducing Risk: Simulation-Based Clinical Systems Testing to Determine New Hospital Readiness for Anaesthesia Services
Authors: Girish Sadhu Narasimha Murthy , Reid Leah , Khalid Fouzia
Published: January 2022

The newly built Women’s Wellness and Research Center (WWRC) replaced the pre-existing Women’s Hospital (WH) as the only provider of tertiary maternity care for the residents of Qatar. The pre-existing WH was smaller, with a 12-bay emergency department, 3 operating theatres, 12 delivery rooms and 220 beds, in shared rooms. The new WWRC facility is significantly bigger, with a 28-bay emergency department, 7 operating theatres over two floors, 26 delivery rooms and 240 private inpatient rooms catering for around 18,000 deliveries per year. New systems, designed over only a few months, would need to promote that same level of high-quality patient care but in a newer, larger and unfamiliar facility.

The aim of the study was to identify and mitigate clinical systems risks, relevant to anaesthesia services, by running

The ‘WWRC Anesthesia Activation Team’ was established to conduct

Approximately 110 hours of simulation were conducted in sites relevant to anaesthesia. Many of the participants had never experienced simulation before but nearly everybody complimented its usefulness and debriefing was unanimously constructive. Testing identified 143 discrete latent safety threats (LST) and were categorized under Facility, Workflow, Personnel, Process, Equipment and Technology (Table 1). Fifty-four LSTs were due to systems that were incomplete at the time of testing but would be completed by the time services commenced. The remaining 89 were significant LSTs which could have resulted in significant clinical incidents. After mitigation of LSTs, the areas were simulation tested again to confirm threat elimination. WWRC was opened only after all areas of concern were addressed. A year after moving, a review of all the changes recommended from the simulation-based systems testing was conducted. It showed that there were no anaesthesia-related clinical incidents in those areas.

Our experience confirms that simulation can identify Latent Safety Threats (LST) prior to a major move to a new facility
46 ‘Born Too Soon’ Virtual Simulation for Ambulance Services On Premature Babies Born Unexpectedly in the Community
Authors: Aguirre Diana , Henry Stephanie , Fernandez Cecilia Perez , Brown Sebastian
Published: January 2022

Premature infants are at risk of death or neurodevelopmental impairment unless prompt effective care is delivered

The aim of the study was to introduce a recurring virtual simulation workshop for WMAS on optimizing the initial care for vulnerable premature infants born unexpectedly in the community.

Our local WMAS lead identified a training need through informal feedback from paramedics about the lack of training and confidence in dealing with premature births. Our workshop, designed to address this need, begins with an overview of prematurity. A simulation session follows, demonstrating basic Neonatal Life Support skills using equipment available to pre-hospital teams, focussing on thermoregulation. It concludes with a question-and-answer session. To enhance pre-hospital thermal care, we also put forward a successful business case for heated gel mattresses to be introduced across the WMAS and incorporated training for its use in the workshop.

Two virtual training workshops have been delivered so far. In 2020, seven paramedics attended, and two completed the feedback and found the session valuable. After advertising, a second workshop was delivered in March 2021. Over 330 WMAS personnel registered, 219 attended and 132 gave feedback. There were representatives of various grades from 16 hubs across the region. Before the session, 12.2% of participants reported feeling somewhat confident/confident attending unplanned premature births of infants <32 weeks’ gestation. Following the session, this improved to 66.7% of participants. Attendees commented on how ‘useful’, ‘fabulous’ and ‘fantastic’ they found the session. The sharp rise in interest in this virtual workshop confirms the training need whilst the positive feedback highlights the effectiveness of the virtual simulation workshop. With enhanced technical support, we will improve the learning experience of participants in the future. This project also led to the successful introduction of heated gel mattresses which are now carried on every WMAS ambulance. We expect that with increased staff training and confidence, the incidence of babies admitted with hypothermia following an unexpected birth in the community will improve with time. Our vision is to expand this project to other regions to empower pre-hospital staff to support premature infants born unexpectedly in the community and improve outcomes.

Published: January 2022

The efficient working of a busy, multi-faceted Healthcare Simulation Centre that caters to many different stakeholders requires a repertoire of protocols and procedures. Standard Operating Procedures (SOPs) ensure all resources are managed as effectively as they can be so that teaching can be continuously delivered at the optimum level.

The aim of this wide-ranging project was to devise a collection of SOPs and accompanying files that regulate the efficient management of resources in a Sim Centre.

A template for SOPs was created, with entries for background, purpose, scope, procedures etc. ensuring each SOP would meet a universal standard for the department. They also must be approved by the Simulation Manager and reviewed annually. Accompanying documents, spreadsheets and online forms to facilitate that the processes outlined in the SOPs would also have to be created.

The SOPs include maintenance and servicing of equipment, loaning of equipment, booking of equipment for teaching and self-directed practise, inventory, management of Simulation spaces and storage areas, stock-taking and ordering of consumables. A suite of instructional documents, data management spreadsheets and online forms have been prepared and are updated regularly in accordance with the procedures outlined in the SOPs. Much of what simulation staff do is learned on the job and losing that institutional knowledge can be devastating for a program. To combat this the SOPs capture the essential steps to efficiently run our centre. The SOPs are useful tools to communicate the correct way of carrying out an activity and are used to orientate and train new technical staff in our centre. Importantly, the SOPs are an integral part of our quality enhancement process, updated regularly, and used to communicate innovations and improvements amongst the wider centre user community. These SOPs and associated resources will be made available to the simulation community upon request.
78 Simulation Integrating Deliberate Practice Method for Developing Assesors of Competence
Authors: Almomani Emad , Sullivan Jacqueline , Mathias Jesveena
Published: January 2022

In response to COVID-19, our organization expanded the critical care beds capacity; however, the number of critical care nurses was insufficient to meet expansion demands. Therefore, non-critical care nurses were deployed to COVID-19 critical care units. The deployed nurses lacked experience and training in critical care. To ensure patient safety, the nurses were assigned to assessors who evaluated their fitness to practice after receiving upskilling training through simulation-based education (SBE). However, due to the massive expansion and rapid deployment process, there was a shortage of competency assessors, highlighting an urgent need to use SBE to develop more assessors. We developed additional competency assessors through simulation embedding deliberate practice and rigorous assessment. Deliberate practice in simulation is described as progressive learning, which includes repetitive performance and rigorous assessment

The aim of the study was to explore the effectiveness of simulation embedding deliberate practice in developing nurse competency assessors.

Eleven assessor candidates were asked to perform competency assessments under simulated conditions. During the simulation, simulated participant (SP) roles were assigned as a bedside nurse and patient relative; the patient was a high-fidelity patient simulator. The assessor candidates were asked to perform a competency assessment of the bedside nurse who should perform the required critical care skills on the patient in the presence of the patient’s relative. The candidates used a valid observation rubric to complete the assessment. Using deliberate practice strategies, after each competency assessment, a debriefing session was conducted in which the SPs provided constructive feedback on the assessor’s performance. The assessor repeated the competency assessment under the same simulation conditions and attended debriefing sessions until they mastered the competency assessment process. Post simulation evaluation collected data to evaluate the candidates’ perception of the training.

Eleven nurses completed the simulation developmental programme and were assessed as competent to become assessors. The questionnaire findings revealed that all nurses perceived themselves as competent assessors; however, 90% reported the need for frequent exposure to the competency assessment process over time, in the clinical setting, to enhance their competence and confidence levels.

The hybrid simulation modality of SP and patient simulator embedding deliberate practice method was deemed to be an effective fast track method to develop competency assessors. However, practice of competency assessment in real clinical settings is essential to confirm competence.
87 Maxsim, A Novel Simulation-Based Education Course for Oral and Maxillofacial Surgical Emergencies
Authors: Holden Adam
Published: January 2022

For Oral and Maxillofacial Surgery (OMFS) Senior House Officers (SHOs), with no formal medical training, the first exposure to inpatient medical or OMFS emergencies will be the first time they are having to manage them, usually alone.

Simulation-based education has been demonstrated to increase experience and confidence when used in medical education; therefore, an OMFS simulation-based education (SBE) course was created to facilitate this learning in a safe environment.

The course included implementation of training on SBAR, A to E Assessment, stations on medical emergencies such as sepsis, and OMFS emergencies centred around scenarios that necessitate rapid response including retrobulbar haemorrhage and carotid artery blowout. Pre- and post-course questionnaires were given to all delegates to assess their change in confidence when managing the scenarios. Each was asked to score their confidence in managing the scenarios numerically from 1 to 10.

Delegate numbers were limited due to the COVID-19 pandemic with all 10 completing both questionnaires. There was an even distribution between first- and second-year SHOs. Two had received simulation training before, however very limited. In all 10 simulation stations, every delegate felt an increase in confidence on average by 45% (range: 38–56%, p < 0.05) on the 10-point scale. Positive feedback was received, with all delegates finding the day useful, it achieving what they hoped and stating they would recommend the course to a colleague. Both the SBAR and A to E tools were unknown to all of the SHO’s, highlighting their lack of medical training as they are well-known tools within the medical community. SBE was demonstrated to increase the experience and confidence of SHO’s managing and escalating common OMFS situations. This will increase the quality of patient care of these specific scenarios but the translatable skills will also enable more comprehensive care and handover in all aspects of the delegates roles. Simulation-based education is an invaluable method of training for clinical scenarios and needs to become more common place in Oral and Maxillofacial Surgery. Furthermore, Health Education England has commissioned the course to run on 3 days annually, providing simulation-based education for 40 SHOs in the Southwest Deanery undertaking a rotation within OMFS.

U radu su predstavljene mogućnosti primjene GIS alata u testiranju različitih oblika i broja primjernih površina kao jedinica uzorka za procjenu površina šuma i šumskog zemljišta u inventurama šuma na velikim površinama radi izbora najprikladnije forme uzorka.

Za testiranja kreirani su različiti modeli uzoraka. Primjerne površine unutar traktova - klastera su formirane u digitalnom obliku i sistematski raspoređene u kvadratnoj mreži čineći uvijek isti stepen izbora u uzorak. Kao uzorak za testiranje korišćeni su stvarni podaci o površinama šuma sa vektorskih karata koje pokrivaju oko jedne destine površine BiH, odnosno površine šuma i šumskih zemljišta. Sve karte su objedinjene na jednom sloju, čime se došlo do jedne jedinstvene karte svih sastojina.

Metodom preklapanja slojeva uz istovremeno preklapanje njihovih baza podataka, dolazi se brzo do rezultata kakav bi se dobio inventurom šuma. Daljnjim statističkim analizama rezultirajućih baza može se doći do odgovora na pitanje koji je od modela uzorka najreprezentativniji i daje najpribližnije podatke o površinama u odnosu na stvarne.

Ovaj rad u suštini ne daje konačan odgovor, već samo usmjerava na metod kojim se može do njega doći. Metod je korišten u razradi uzorka za provođenje druge državne inventure šuma u Bosni i Hercegovini.

Gazdovanje privatnim šumama koje zauzimaju 50% šuma u Srbiji u mnogome je otežano postojanjem velikog broja privatnih šumovlasnika (oko 500.000), malom prosečnom površinom šumskih poseda (0,26 ha), velikim brojem katastarskih parcela iz kojih su posedi sačinjeni (3.900.000) i fragmentisanošću tih parcela. Proces tranzicije u kome se Srbija nalazi praćen je zakonodavnim i organizacionim reformama, poboljšanjem javne administracije i institucionalnim jačanjem, promenom vlasništva nad šumom kao posledicom proceca denacionalizacije, ali i promenama načina upravljanja i odnosa državne uprave prema privatnim šumama. Trenutni problemi privatnog šumarstva Srbije ogledaju se u neadekvatnom odnosu države prema privatnim šumama ali i samih vlasnika prema njihovom vlastitom posedu. Zbog toga se od javne administracije očekuje da pruži značajne mere podrške privatnim šumposedima u cilju iskorišćenja potencijala privatnih šuma i podrške razvoju ruralnih područja. U ovom radu je prikazana komparativna analiza podrške državne šumarske službe privatnom šumposedu u Srbiji i Sloveniji.

U ovom radu govori se o pojavi sušenja hrasta kitnjaka [Quercus petraea (Mattuschka) Lieblein] u Bosni i Hercegovini, koja se posljednjih godina sve više širi. Posebna pažnja je data žutoj imeli Loranthus europeus koja je inače vrlo česta u našim šumama hrasta. Posljednja istraživanja pojave imele na planini Motajici upozoravaju da je ovo nova prijetnja potrajnom gazdovanju ovim šumama. Na ovaj način sušenje hrasta koje prouzrokuju drugi faktori okoline (na primjer, klimatske promjene), može se dalje pogoršavati. Intenzitet imelom napadnutih stabala na eksperimentalnoj plohi iznosio je 11,8% u debljinskoj klasi 20-30 cm, a čak 77,8% u debljinskim klasama iznad 70 cm. U zaključku se ističe da je nedostatak odgovarajućih gazdinskih mjera bio jedan od faktora koji je uticao na širenje imele.

Za racionalno gazdovanje šumama i pravovremeno provođenje svih planiranih biotehničkih mjera, neophodno je izgraditi dovoljno gustu i razgranatu mrežu šumskih saobraćajnica. Pri tome se ima u vidu da putevi nemaju značaj samo za proizvodni aspekt šume, već i za sve ostale mnogobrojne aspekte: ekološki, sociološki, zaštitni itd. Najbolje rješenje u otvaranju šuma jeste kada se postigne da se sa što manje uloženih sredstava dobije što bolje otvorena šuma. Rezultat kojem se teži u otvaranju šuma jeste optimalna mreža šumskih saobraćajnica. Optimalizaciju mreže šumskih saobraćajnica je moguće uraditi pomoću matematičke formule minimiziranjem ukupnih troškova. Metode koje optimalizaciju mreže šumskih saobraćajnica rade pomoću računara, analiziraju veći broj faktora i imaju različit pristup u rješavanju otvaranja.

U ovom radu je izvršena analiza na osnovu koje su se dobila područja pogodna za gradnju šumskih kamionskih puteva. Uticajni faktori koji su se uzeli za analizu su: normalna zaliha, dubina zemljišta i nagib terena. Nakon bodovanja područja, koja su za svaki od uticajnih faktora ponaosob manje ili više pogodna za gradnju šumskih kamionskih puteva, dobila se zbirna tematska karta. Na njoj su izdvojena područja koja su pogodna i područja koja nisu pogodna za gradnju šumskih kamionskih puteva.

Shodno klimatskim promjenama koje se dešavaju, već sada sa vidljivim posljedicama, neophodne su ljudske intervencije u cilju poboljšanja adaptacije vrsta sa isprekidanim (disjunktnim) arealima. U izmijenjenim ekološkim uslovima na udaru su najosjetljiviji šumski ekosistemi, a među njima sigurno i šume hrasta kitnjaka. Zato je očuvanje najkvalitetnijih sastojina ove vrste od višestrukog značaja. Tu treba izdvojiti i potrebu unapređenja sjemensko-rasadničke proizvodnje te je usmjeriti u pravcu proizvodnje sadnog materijala za klimatske uslove koji se predviđaju u narednih 50-100 godina.

Predmet istraživanja je sjemenska sastojina hrasta kitnjaka (Quercus petraea/Matt./Liebl.) starosti 100 godina na području šumskog gazdinstva Banja Luka. U periodu 2006.-2009. godine vršena su konstantna opažanja u sastojini koja su započela sa obilježavanjem i izdvajanjem sjemenskih stabala, prvim proredama (veoma slabog intenziteta 3%), praćenja obilnosti cvjetanja i plodonošenja te evidencije zdravstvenog stanja. Na osnovu prikupljenih podataka daje se prijedlog mjera koje će se obavljati u narednom periodu. Uvažavajući biološke i ekološke aspekte analizirane vrste, osjetljivost i složenost sastojina hrasta kitnjaka, te njihovu reakciju na klimatske promjene, sprovođenje genetičkih melioracija u sjemenskim objektima može značajno doprinijeti unapređenju proizvodnje sjemena ove vrste.

Within last few years, all Western Balkan countries have adopted new forest legislation aiming to introduce internationally accepted concepts of forest management. Due to specific social, political and economical realities that these countries have passed through, a number of nature protection regulations have been integrated into forest legislation. This paper compares nature protection regulations in Laws on Forests in Croatia (2005), Federation of Bosnia and Herzegovina (2002) and Serbia (2010). It examines differences and commonalities in above mentioned Laws. Furthermore, the paper analyzes the level of consistencies between Laws on Forests and Laws on Nature Protection in Croatia (2005), Federation of Bosnia and Herzegovina (2003) and Serbia (2009) in terms of “openness” and “greening” of forest related legislation. The results show that protection regulations within forest legislation, particularly those referring to forests with special management regime, can be strengthened by introducing the concept of high conservation value forests (HCVF). This concept includes also strategic changing of forestry sector position - from an inferior towards more proactive role in nature protection dialogue. The results of this paper can contribute to further improvements of current countries’ forest related legislation in domain of analyzed issues as well as creation of consistent forest and nature protection policies aimed at fostering cross-sectoral dialogue and cooperation.

Rad obuhvata istraživanje otpornosti na sušu pet provenijencija bukve iz dijela prirodnog areala sa prostora Bosne i Hercegovine. Sjemenski materijal za ova istraživanja sakupljen je u jesen 2007. godine iz kojeg je, naredne 2008. godine, proizveden sadni materijal na kojem je vršeno testiranje otpornosti.
Na osnovu rezultata testa na sušu i izračunatih „letal dosis 50“, može se zaključiti da su razlike u otpornosti na sušu među istraživanim provenijencijama evidentne. S obzirom na to da istraživane provenijencije potiču iz područja u kojima vladaju različiti eko-klimatski uvjeti, navodi na zaključak da je osobina otpornosti na sušu nasljadna. Rezultati ovih istraživanja predstavljaju dobar osnov za selekciju sjemenskog materijala iz kojeg će se u budućnosti proizvoditi sadni materijal za pošumljavanje ekstremnijih staništa.

Vitamin C or ascorbic acid content has been determinated by spectrophotometric method and titrimetric method in flowers of some Bosnian hawthorns (Crataegus L). species. Spectrophotometric method used in this study was based on the kinetic reaction between Vitamin C and methylene blue. Measurements were carried out at absorption maximum, λmax= 665 nm. We found that the lowest content of vitamin C was 617.07 mg/100 g of dry sample in flowers of the C. microphylla, and the highest level of Vitamin C was found in the C. monogyna (1104 mg/100 g of dry sample) flowers. Recoveries of the results obtained by the spectrophotometric method were 94 % - 100% with relative standard deviation (RSD) values from 4.5% – 6.7 %.

Obtained results shown that flowers of investigated Crataegus L. species are good source of vitamin C.

In order to define functional model of governing of forest resources in F B-H, as well as efficient and effective organizational model of the forest enterprises, qualitative research has been conducted for the purposes of this paper. Through direct interviewing of all key forest policy decision makers in F B-H, opinions and attitudes about these questions were collected. Based on analysis of interest groups importance as well as influence and involvement in the process of creation of the functional forest governing model in F B-H - functional governing model has been proposed with clear emphasis of advantages concerning present model.

Principles of sustainable governing and management of forest resources, assurance of participative approach in the process of decision making and transparency were basis for definition of functional governing model for management of forest resources.

For provision of optimal model of organization of forest sector in F B-H, it has been crucial to define ecological, sociological, economical and other criteria, that user of forest resources should respect. The optimal number of organizational units, which manage forest resource on the territory of F B-H, depends from the achievement of the established criteria and real capacities for establishment of the enterprise. This would lead to further decentralization in management of forest resources in F B-H; that would have its positive effects.

Research results of the stand volume increment changes in mixed forests of beech, fir and spruce on limestone and dolomite in Federation of Bosnia and Herzegovina (FB&H), is presented in this work. Impact of different factors to volume increment value was investigated: habitat quality, values - indicators of structural characteristics particular forest stands, and orographic characteristics if the terrain. Impact of climate differences was investigated trough position of the forests stands in particular ecological-vegetation regions in B&H. Research was done on example of 799 forest stands, trough complex methods of multiple regression analyses, and variance analyses (ANOVA), The results shows that volume increment of the forest stands, besides taxation values: basal area, relative share species in volume, average diameter of the trees, medium height of the trees 50 cm in diameter, significantly depend of the altitude and belonging to particular ecological-vegetation regions in B&H.

The result of the analyses is complex model for forest stand volume increment assessment. It was concluded that volume increment of these forest is higher about 1 m3/ha, now than 50 years ago, when very similar investigation was done in the same forests.

The research has been carried out in a formal experiment with silver fir near Očevje-Olovo, with nine provenances originating from natural BiH population of 22 years of age. The research observed following provenances: communities from the area of Bugojno, Bosanski Petrovac, Olovo-Palež, Olovo-Klis, Pale, Konjic, Fojnica, Sokolac, and Prozor.

The analysis of diameter on the root collar found that there are statistically significant differences among the provenances. It was also found that the biggest diameter on the root collar was on the provenances of Fojnica, with 75.6 mm, whereas the smallest was on the provenances of Olovo-Klis, with 65.2 mm. In terms of breast height diameter, some statistically significant differences were also found, so that the biggest diameter was on the provenance of Fojnica, with 47.0 mm, whereas the smallest value of this feature was on the provenance of Pale, with 41.6 mm.

The analysis of the height of different provenances for the testing period, 1999 – 2005 (7 years), suggested statistically significant differences among the provenances. The biggest value was on the provenance of Bosanski Petrovac, with 407 cm, whereas the smallest height was on the provenance of Olovo-Klis, with 364 cm.

The results obtained during this research provide valuable information, which can be used as indicators for successful differentiation of silver fir.

Natural interspecies hybrids of black (Alnus glutinosa (L.) Gaertn) and grey (A. incana (L.) Moench) alder are not frequent in nature but they are registered, and according to modern systematic nomenclature are classified within nothospecies A. × pubescens Tausch.. Since the presence of spontaneous intermediate forms of the genus Alnus in Bosnia and Herzegovina is insufficiently explored, the first results of comparative morphological analysis (seven leaf’s characters) of black and grey alder and their hybrids are given in this study. About 10% of hybrid individuals were present in the studied sympatric populations, and they had more heterogeneous leaves than parental species. Good diagnostic characters showed intermediate values in comparison to the parental species, which are: number of pairs of lateral veins, angle from the top of the leaflet to the top of the upper 3rd nerve, and distance from the top of the leaflet to the top of the upper 3rd vein. According to analyzed characters, hybrids either hold intermediate positions between the parental species or are closer to the maternal species (A. incana). Three new findings of nothospecies A. × pubescens for Flora B&H are rivers’ localities Drinjača near Kladanj, Turbe near Travnik, and Stavnja near Vareš. Due to the low frequency of observed individuals of A. x pubescens, they are vulnerable and require special measures of protection and biodiversity conservation activities of autochthonous gene pool, it is necessary to determine the actual state in all previously published hybrid complexes’ findings and expand researches in B&H in the coming period.

This work researches structural composition, texture and diversity of development phases of virgin forest „Ravna vala“ on Bjelašnica. Virgin forest „Ravna vala“ is located in central part of Bosnia and Herzegovina, about 20 km south west from Sarajevo on mountain Bjelašnica, on altitude of 1280 to 1450 m. First time it was described in 1978. Within it we have positioned permanent plot of the square shape in size of 1 ha. Research was conducted on permanent plot in three time series: in years 1978, 1988 and 2008, and on 46 temporary systematically positioned circular plots in diameter of 12.6 meters, where each represents as per 1 ha of virgin forest area. In virgin forest we have registered 689 trees per hectare and wood supply mass of 701 m3/ha. Through analysis of dynamics of growth of specific species trees, it is visible that beech suppresses fir, i.e. there is a shift in main species in virgin forest, therefore, in the last 30 years number of beech trees has tripled in the lower diameter classes. Virgin forest has mostly present optimum phase and evenness phase, and rejuvenation phase. Texture diversity is expressed through Shannon index in value of 1.69, and evenness index has the value of 0.86.

This paper presents the results of a comparative analysis of the structural and vegetation characteristics of "Ravna vala" pristine (virgin) forest and the managed forest of beech and fir (with spruce). Pristine forest "Ravna vala" is located in the central part of Bosnia and Herzegovina, about 20 km southwest of Sarajevo on Bjelašnica Mountain, at an altitude from 1280 to 1450 m. The managed forest of beech and fir with spruce, which was used for comparison, borders "Ravna vala" and has the same habitat conditions: climate, orography and land, and the similar structural characteristics and composition of tree species as the pristine forest.

Beech and fir communities (Abieti-Fagetum illyricum Treg. 1957) dominate but spruce can also be found in the area of ​​research. Noble hardwoods such as sycamore and elm are found both individually or in small groups in depressions in deeper soils.

Both the pristine forest and the managed forest show the selective diameter structure. However, the great differences between the pristine forest and the managed forest are final diameter classes. The thickest tree in the pristine forest has the breast diameter of 145 cm, while the diameter of the thickest tree in the industrial forest is 70 cm. The volume of the stands is 770 m3/ha in the pristine forest and it is two times larger than in the managed forest. The volume of dead wood in the pristine forest is 170 m3/ha and it is five times larger than in the managed forest. While stumps and thicker branches are the most common in the stock of dead trees in the managed forest, the most common in the stock of dead wood in the pristine forest are tall stumps as well as lying and standing dead trees. Floristic researches have shown that selective management does not reflect negatively on floristic diversity, but ground vegetation is richer in species in the managed forest. Shannon's diversity index and evenness index of vascular flora have higher values ​​in the managed forest. Unlike floristic diversity, the stand diversity index of Jähne & Dohrenbusch (1997) shows higher values ​​in the pristine forest than in the managed forest.

The antioxidant activity of aqueous and aqueous-ethanolic extracts from lemon balm, rosemary and sage leaves were investigated using the Briggs-Rauscher reaction method. This method is based on the inhibitory effects of antioxidants on the oscillations of the Briggs-Rauscher reaction mixture. The extracts from examined plants were prepared using process maceration at room temperature and boiling temperature under reflux conditions. The inhibition times produced by addition of examined plant extracts on an active Briggs-Rauscher reaction mixture were followed potentiometrically. Relative antioxidant activity was determined on the basis of inhibition time using rosmarinic acid as standard. The aqueous extract from sage obtained at boiling temperature under reflux conditions showed the best ability to inhibit oscillations ie. the highest antioxidant activity. The antioxidant activity for six two-component mixtures of aqueous extracts obtained at boiling temperature under reflux conditions was also investigated.

This paper presents an analysis of full-length method used in the phase of sessile oak felling and sorting works. The aim of the research was to establish time consumption during sessile oak felling and sorting works using full-length processing method. The research was conducted in the area managed by Forest enterprise "Šumsko – privredno društvo Zeničko-dobojskog kantona" Zavidovići, Management unit "Šumarija" Olovo, Forest unit "Krivaja", compartment 112. The sampling method was applied for measuring time consumption of work operations. It was established that the share of effective time in total time was 67.12%, the share of unavoidable delay times was 30.79%, and the share of avoidable delay times was 2.09%. Time consumption of tree felling and processing was strongly affected from tree diameter at the breast height (R2=0.656). The achieved results will be used for further research on this topic, which has been unduly neglected in the past few years in the BH forestry. Further research would certainly include ergonomics, economy of work procedures, occupational safety and environmental consequences of forestry work.

The paper displays research results of volume increment size of main tree species, fir, beech and spruce within mixed forests of beech, fir and spruce on limestone and dolomites in Federation of Bosnia and Hercegovina (FBiH).

Fir and beech forests along with the spruce represent the most important part of forest resources in BiH. As LOJO (2013) points out, around 371 000 ha of these forests are located on limestone and dolomites and are selection forests for the most part. Knowledge of laws of changes in size of volume increment of selection stand of trees is necessary for high quality planning of forestry production. The paper explores changes of volume increment sizes especially for following tree species: fir, spruce and beech within mixed stand of trees. Research sample are measured sample plots from 799 mixed stand of trees larger than 40 ha recorded during 11 years' time during the creation of forest management plans. Stands of trees in which control recordings were conducted for the purpose of reliability of data were taken as a sample. Multiple regression models for estimation of volume increment size of fir, spruce and beech including two models for each species of trees. Models used for volume increment size estimation of mixed forest in optimal - normal state and models used for determination of volume increment that is as accurate as possible when the size of multiple independent factors that affect change in volume increment size are known. This paper explores dependence of change of volume increment on: site class expressed through average height of trees whose diameter is 50 cm, share of species of trees in the stand volume, degree of coverage of the ground with crowns of trees of medium diameter in stand of trees which was calculated based on the basal area of species of trees and share of deciduous trees in the stand of trees volume. For more precise model size of basal area of species of trees in stand of trees and average altitude were used.

Published: January 2022

El objetivo del estudio se orienta a analizar las políticas institucionales implementadas en la Universidad Nacional de Río Cuarto (UNRC) (Córdoba, Argentina) para la gestión de la enseñanza durante la emergencia socio-sanitaria. El estudio de caso se aborda mediante una metodología cualitativa utilizando como procedimientos de recolección de datos el análisis de documentos institucionales y entrevistas a autoridades académicas. Se privilegia el enfoque teórico de la puesta en acto de las políticas de Stephen Ball. Los datos permiten identificar tres momentos en el proceso o ciclo de construcción y puesta en acto de las políticas académicas de la UNRC orientadas a garantizar la continuidad de la formación de grado de sus estudiantes: 1) la irrupción de la pandemia con la consiguiente alteración de la lógica universitaria; 2) la construcción de políticas y normativas locales para hacer frente al acontecimiento; y 3) planificación de la pospandemia. Mediante el análisis de estas etapas el artículo da cuenta del impacto de la pandemia de COVID-19 en los patrones de decisión y operación de la gestión universitaria en la emergencia socio-sanitaria.
