ABSTRACT

A teacher's primary responsibility is to plan, implement, and evaluate learning. The teacher's main task in preparing lesson plans is the one that must be completed before the teacher begins to learn. Learning planning activities are carried out by preparation for learning management. One of the learning management tools that teachers need to prepare is school supplies, one of which is lesson plans. The implementation of learning is done by the teacher both inside and outside the classroom. The learning carried out must be in accordance with the prepared plan. The teacher's next task is to conduct the assessment. Assessments are made to measure student academic success and teacher success. In addition, based on these results, the teacher conducts follow-up activities. Learning planning activities need to be carefully prepared to facilitate teacher learning. Plan learning through activities to develop fundamental skills in a learning device. Lesson plans can be done independently or in a group of teachers. The preparation of teaching materials in the form of lesson plans and implementation plans can be done through workshops. Workshops can increase teachers' effectiveness in creating learning tools.

Authors: YÜCESAN Esra
Published: January 2023

Purpose: This study aims to examine pre-service preschool teachers’ music education self-efficacy levels in terms of their gender and grades.

Design: The research has been designed as descriptive research based on the survey model. The data collection tool includes the 'Music Education Self-Efficacy Scale for Preschool Teacher Candidates' developed by Yıldız (2017). The study group includes 221 pre-service preschool teachers.

Findings: Research indicates that pre-service preschool teachers' music education self-efficacy is at a 'good level.' Considering grades, it is found that as the grade level increases, there is an increase in the self-efficacy beliefs of pre-service preschool teachers related to music education. The lowest music education self-efficacy levels belong to freshman pre-service preschool teachers, and the highest music education self-efficacy levels belong to senior pre-service preschool teachers. However, it is found that the music education self-efficacy levels do not significantly differ according to gender.

Highlights: It draws attention to a significant increase in the music education self-efficacy belief levels of the 3rd and 4th grade pre-service preschool teachers who took 'Early Childhood Music Education' as a compulsory course in the 2nd year of undergraduate education.

Published: January 2023

The purpose of this study was to extend our knowledge of the testate amoebae in Hungary. Soil and to a lesser extent sediment samples were investigated in the frame of the 2. Biodiversity Day in Hungary, organized in a 1 km2 area around the abandoned south-transdanubian village Gyűrűfű in the Zselic Hills. No former studies were conducted in the area focusing on terrestrial testates. 53 taxa were recorded, some of them 2nd (Centropyxis plagiostoma terricola) or 3rd (Centropyxis elongata) detection in Hungary. The testacean assemblages with prevailing Centropyxis and Plagiopyxis species reflected an arid character of the sampled soil, devoid of most Nebelid species except for Heleopera; Nebela spp. were completely absent. The sediment was collected from small wet areas frequently drying out in summer, thus, the aquatic assemblages contained many eurytopic or terrestrial and less aquatic taxa.

Published: January 2023

OBJECTIVE

American bison (Bison bison) quarantine protocols were established to prevent transmission of brucellosis outside the Greater Yellowstone Area, while allowing for distribution of wild bison for conservation and cultural purposes. Quarantine standards require rigorous testing over 900 days which has led to the release of over 200 bison to Native American tribes. Standards were evaluated using 15 years of laboratory and management data to minimize the burden of testing and increase the number of brucellosis-free bison available for distribution.

ANIMALS

All bison (n = 578) from Yellowstone National Park were corralled by the National Park Service and United States Department of Agriculture.

PROCEDURES

A statistical and management evaluation of the bison quarantine program was performed. Bayesian latent-class modeling was used to predict the probability of nondetection of a seroreactor at various time points, as well as the probability of seroconversion by days in quarantine.

RESULTS

At 300 days, 1 in 1,000 infected bison (0.0014 probability) would not be detected but could potentially seroconvert; the seroconversion model predicted 99.9% would seroconvert by day 294, and 12.8% of bison enrolled in quarantine would seroconvert over time. Using a 300-day quarantine period, it would take 30 years to potentially miss 1 seroreactor out of over 8,000 bison enrolled in the quarantine program.

CLINICAL RELEVANCE

Reducing the quarantine program requirements from over 900 days to 300 days would allow management of quarantined bison in coordination with seasonal movement of bison herds and triple the number of brucellosis-free bison available for distribution.

Published: January 2023

Biomedical waste is a well-recognized environmental problem, yet less is known about the waste generated in the delivery of veterinary care compared to human medicine. The objective of this project was to develop and pilot a waste audit protocol for veterinary medicine that could inform waste management at a US university veterinary teaching hospital and the broader veterinary community. We conducted a multi-day review of the Colorado State University Veterinary Teaching Hospital’s small animal surgery and anesthesia units to measure the types and amounts of waste generated during routine surgeries. Metrics included total weight, number of bags, and individual counts for specific items of concern and items with sustainable alternatives. We calculated frequencies and percentages of waste by waste audit material category and noted any erroneous materials sorted. Despite waste being a prioritized sustainability issue in veterinary medicine, this work highlighted opportunities for better education on managing and optimizing existing resources through behavior modification. This article explores ways the 5Rs (Rethink, Reduce, Reuse, Recycle, Research) could be better operationalized in veterinary hospitals.

Published: January 2023

The tradition of drinking wine has a very old history. Romania has a very good geographical location and a favourable climate for grapes; it is ideal for growing vines and producing quality wines. In our research, we analysed quantitative and qualitative parameters of four varieties of grapes in the Miniş-Măderat Vineyard. The objective was to look for differences between traditional varieties (Cadarcă/Kadarka and Fetască Neagră/Fekete Leányka) and world varieties (Cabernet Sauvignon and Merlot). From the data, it could be concluded that the worldwide-known varieties yielded better results, but for a new plantation in the Miniş-Măderat Vineyard, we recommend the use of traditional varieties, as they have a better history in the area.

Published: January 2023

Floodplain ecosystems are hotspots of biological diversity and perform important ecosystem functions in the landscape. The key to understanding the sustainability of ecosystem function is knowledge of the relationships between ecosystem components. The article reveals the role of morphological and physical properties of soil, as well as phytoindication of environmental factors as drivers of biological diversity of soil macrofauna of protected ecosystems of the Dnipro River floodplain. The studies were conducted in the forest floodplain ecosystems of the “Dnipro-Orilskiy” Nature Reserve. The studies of morphological properties of soils allowed us to identify the representatives of two reference groups: Fluvisol and Gleysol. The soil physical property data were subjected to principal component analysis, which extracted four principal components whose eigenvalues exceeded unity and described 79.9% of the variation in traits. The principal components of variation in soil physical properties and phytoindication assessments of environmental factors were used as predictors of the community structure of soil macrofauna. These predictors were able to explain 29.6% of the community variation. Physical soil properties are most important as a driver of soil macrofauna. The morphological properties of the soil and phytoindicator assessments are able to explain a much smaller part of the community variation. The pure influence of the predictors is small, indicating that they interact significantly in influencing soil animals. The results obtained have implications for the development of optimal strategies for floodplain ecosystem management and biodiversity conservation.

Authors: Abdullah Neven A. , Sh. Al-Jabir Haider S. , Shareef Hussein J.
Published: January 2023

In light of global warming, pre-treatment plants with antioxidants may reduce the damage caused by climatic changes. Indian almond seedlings were planted in pots subjected to ascorbic acid and potassium chloride alone or combined to reduce the negative impact of high field temperature. Compared with the control, all treatments improved the plant height, branch number, number of leaves, and leaf area. These treatments reduced loss in concentration of photosynthetic pigments such as chlorophyll a, chlorophyll b, total chlorophyll, and carotenoid. Heat stress increased abscisic acid content and electrolyte leakage percentage, whereas the application of ascorbic acid alleviated this damage. Indian almond plants can better withstand high temperatures particularly using ascorbic acid treatments at 50 mg l−1 or treatment of ascorbic acid at 50 mg l−1 + potassium chloride at 250 mg l−1 to reduce heat stress damage.
Impact of M&A Announcements on Listed Firms in the Iberian Markets
Authors: Lobo Bruno F. S. , Gomes Luís M. P.
Published: January 2023

Mergers and/or acquisitions (M&A) are important business operations for firms that wish to diversify, become stronger and more competitive. The main objective of this paper is to investigate the impact of M&A announcements on the abnormal stock returns of firms listed on the Portugal and Spain stock exchanges. The empirical work analyzed 29 trades in the PSI-20 and 25 trades in the IBEX-35, since the year 2000, using the event study methodology. Most of the research investigates corporate combinations that take place in international markets and among large firms. Therefore, a first contribution of this paper is to study the phenomenon in smaller markets and firms. The results suggest that the two markets react differently to announcements of M&A. Overall, the findings seem to show that in the Portuguese market the joint firms present average gains and that in the Spanish market the joint firms present average losses, bidders have sharper reactions and targets have higher losses. The study also indicates that the abnormal returns of the Portuguese firms (especially the bidders) and the Spanish bidding firms tended to stabilize around a week after the announcement date. This conclusion is another useful contribution of the paper for academics and decision makers of corporate restructuring.

Authors: Roşu Bogdan , Cordun Mariana
Published: January 2023

Introduction. To control the movement, the brain must process proprioceptive information provided by mechanoreceptors. The role of proprioception in carrying out daily activities and physical exercises, was presented, using the SEBT technique and the proprioceptive mechanisms that represent the base of dynamic postural control.

Objective. The aim was to highlight the effects of proprioceptive training on lower limb balance in subjects with lower limb injuries but also in healthy subjects, and to evaluate the effectiveness of proprioceptive programs based on postural instability to reduce knee sprains by developing proprioceptive control. These findings indicate the improvement of proprioceptive control which may be a key factor in reducing knee sprain.

Working hypothesis. Applying a kinetic intervention protocol, consisting of static proprioceptive exercises, stimulates the body to maintain balance in situations of imbalance and increases the stability of the knee joint in Ministry of National Defense workers with a history of sprained knee or predisposition to injury.

Methods. The research was performed on 30 subjects, male and female, employees of the Ministry of National Defense, distributed in two experimental groups: G1 and G2.

Results. The results demonstrate the effectiveness of the applied program, both for therapeutic and prophylactic purposes, in increasing postural balance and proprioceptive control.

Conclusions. Knee sprain is a trauma that occurs frequently among athletes. Like athletes, the Ministry of National Defense employees represent a population at high risk of injury or recurrence.

The impact from the increased discharge of domestic and industrial waste, as well as other human activities, has had a significant negative impact on the quality of water in the TukadBadung River Estuary, which is a natural habitat for mullets (Mugil cephalus). In seeking to understand the response of aquatic organisms to this environmental change, one important biomarker of environmental stress is the histopathological features of fish liver. The measurement of water quality parameters in TukadBadung Estuary showed a normal range of dissolved oxygen (8.07), pH (7.01) and temperature (28.50C). However, the measurement results for the heavy metals chromium (Cr) in Station I (0.086 mg/L), Station II (0.099 mg/L), and Station III (0.099 mg/L) all exceeded the water quality standard threshold, based on the KepMen Negara LH No. 51 Tahun 2004 standard for seawater quality (seawater biota). The results of the observation of histopathological features of the liver organ of mullets (Mugil cephalus) in the TukadBadung Estuary revealed various physical damage, including signs of haemorrhagic, congestion, vascular degeneration, and focal necrosis.

Published: January 2023

Coral transplantations are widely conducted at the coastal areas where corals are both fragmented and transplanted out of the water, exposed to open air and sunlight directly. However, the effectivity of these methods remain poorly understand due to different physiological type of corals. Coral Acropora jacqulineae is one of common transplanted coral for ornamental aquarium. The aim of this reseach was to examine the survival rates of fragmented and transplanted A. jacqulineae both in the water and out of the water. Each coral donor was fragmented with different initial sizes (3, 5 and 7 cm). All the fragments were cemented on the artificial substrate and arranged on the metal table which has been set on the sea floor at 15 m prior to the experiment. The survival rates were measured in every month for 9 months. The differences of the survival rates of fragmented and transplanted coral fragments both in the water and out of the water were analysed by using Fisher’s Exact test (P = 0.05). According to Fisher’s Exact test that the survival rates of coral A. jacqulineae fragmented and transplanted both in the water and out of the water were no significantly different. It is suggested that this condition occured within 2 hours. Therefore, coral A. jacqulineae is one of the coral that can be used in transplantation activity where coral takes out of the water. Nevertheless, this activity has to be done within 2 hours, otherwise it may bring lethal effect to the coral`s metabolism due to stress.

Mangroves are plants that play an important role in maintaining the fertility of mangrove ecosystems by contributing organic material derived from leaf litter. The rate decomposition of leaf litter is a destruction process by dead organisms into smaller particles. The decomposition process of mangrove leaf is affected by lignin and wax in nitrogen supply, environmental conditions, abundance of organisms, and air temperature. This research aims to determine the decomposition rate of leaf litter and percentage decomposition of Bruguiera gymnorrhiza and Sonneratia alba in mangrove forest area in Penyu Island, Tanjung Benoa, Bali. This research was conducted from February to April 2017. The method in this research used litter trap method. The location of the stations was based on the distance of the mangrove trees to the sea. Litter traps were placed on the six (6) stations. During the 60 days of decomposition process, Sonneratia alba leaf was decomposed faster than Bruguiera gymnorrhiza. The highest decomposition rate of Sonneratia alba leaf litter found at station 1 (1.7 g/day) with 99.9% decomposed, and the lowest at station 2 (1.38 g/day) with 99.64% decomposed.  The highest decomposition rate of Bruguiera gymnorrhiza leaf litter found at station 1 (1.52 g/day) with 98.88% decomposed, and the lowest at station 2 (0.99 g/day) with 84.66% decomposed.

Nitrate (NO3-) and phosphate (PO43-) are two parameters of water quality that are important for aquatic organism. Circulation of ocean currents can distribute nitrate and phosphate from one place to another. The current pattern in the waters of the Lombok Strait at the time of the tide moves from the north to the south by bringing the mass of water from the Pacific Ocean, while the movement of the current pattern at low tide moves from south to north by bringing the mass of water from the Indian Ocean. Therefore, this study aims to determine the fluctuations of Nitrate (NO3-) and Phosphate (PO43-) in Lombok Strait during one tidal period. This research was conducted on 3 - 5 November 2017 precisely at coordinates 116?1'18 "LS; -8?34'12 "BT. Sampling is done directly in the field. Seawater samples are taken on the surface and at a depth of 10 meters for 1 x 24 hours with an interval every 2 hours using a Vertical Water Sampler. Measurement of nitrate parameter using spectrophotometric method with Spectrophotometer SNI 6989 79-2011, while phosphate parameter using spectrophotometric method with UV-Vis Spectrophotometer, refer to SNI 06-6989 31-2005. The concentration of nitrate and phosphate at each time in the analysis and seen fluctuations. The concentration of nitrate and phosphate in Lombok Strait fluctuated during one tidal period. At high tide conditions, the concentrations of nitrate and phosphate are low and at low tide conditions high nitrate and phosphate concentrations.

Construction along the coastline has impacts and threats to coastal areas. Incompatibility and deficiency in building construction along the coast can be detected by observing shoreline changes that happen before and after construction. Along with technology advances and science, coastline change can be detected by using numerical modeling. Beach in Kuta District in the Bali Province is a tourist destination that has a coastal erosion problem. Analysis of shoreline changes at the study location is estimated by using numerical simulations (one-line model) to find out the coastline changes that happen on Kuta District for 25 years after the construction of beach protector and sand nourishment. The results of numerical modeling shoreline changes in all study locations over 25 years show an erosion and accretion with the amount of erosion change rates ranging from 1 to 2 meters per year. The analysis coastline change in Kuta District shows that the changes are classified as moderate to large, on the beaches in the north of Kuta Village such as on the beach of Legian Village and beach of Seminyak Village which did not have protection or beach protector such as the German Beach and the Kuta Beach with breakwater, groyne, revetments or handling erosion with sand nourishment.
