Published: July 2023

Sexual harassment and assault are the factors that decrease youth quality employment. The research aim is to explore students’ beliefs and exposure to sexual harassment and sexual assault in selected countries of the European Union underpinning the elaboration of implications for higher education. Theoretical analysis and modelling were used. The exploratory study was implemented to investigate the relationship between students’ self-assessment of their beliefs and levels of exposure in relation to sexual harassment and sexual assault in the selected countries of the European Union. The theoretical analysis resulted in the establishment of the inter-connections between sexual harassment and sexual assault, on the one side, and students’ employment and work/job, health as well as non-direct economic impact, on the other side. The exploratory study revealed that the level of students’ belief is higher if compared to the level of exposure to sexual harassment and assault. Students most believe that people physical appearance, race and being young impact sexual harassment and sexual assault. Exposure to sexual harassment and sexual assault coincide in relation witnessed sexual harassment and sexual witnessed assault as well as their ranking. Implications for higher education refer to teaching staff in higher education. Further research directions were proposed.

Published: July 2023

The question at what age a child should start compulsory education raises debates both in the scientific and public interest contexts. This topic is also relevant all over the world, but a uniform answer is still not found, so the problem of the research emerges - the disclosure of the prerequisites for the change of the educational content during early primary education. The article raises questions related to the possibilities and assumptions of early school entry age for children and the structuring of educational content. 12 education experts and 6 preschool and primary education pedagogues participated in the study. Qualitative research methodology was chosen for this study: semi-structured interview and group discussion methods. During the research, 4 main topics were distinguished. They are as follows: relevance of lowering the school entry age of children; changes in the educational content when the educational age is advanced; characteristics of age change; change processes taking place in the education system. The research findings state that in order to lower the compulsory school age and achieve quality education, it is necessary to reform the educational content: educational programs must be reviewed, reasoned and changed, educational methods and tools must be selectedin a more detailed way, new educational environments created and developed, the evaluation system has to be changed, and teachers must be properly trained to work with younger children.

Published: July 2023

Today’s teachers must be ready to address all students, whatever their abilities, needs, and knowledge. Prospective teachers must develop the necessary competencies during their studies to ensure inclusive education for all pupils. Teaching practice remains one critical means of exposing future teachers to actual classroom experiences to equip them with pedagogical skills. The course followed in this study included teaching practice to allow future teachers to put their theoretical knowledge into practice. The research aimed to analyse future teachers’ feedback after teaching practice in an inclusive classroom. These data – the prospective teachers’ findings after the teaching practice – were analysed using content analysis. The sample of the study consisted of 97 future teachers. The results showed that the student teachers faced various challenges, e.g. needing more experience in an inclusive setting, creating activities that included all students, and needing more teaching resources. However, most were optimistic about the opportunity to put the knowledge they gained during the course into practice. Therefore, teacher educators should ensure that students are prepared for entry into the teaching profession and have a positive pedagogical experience in an inclusive classroom. The teacher educators should also have sufficient knowledge and skills to work with all pupils.

Published: July 2023

The study is devoted to the actual problem of the formation of social competence of adolescents. The aim of the research is to present the theoretical essence of the social competence and try the method of forming the social competence of teenagers out in practice. It is stated that the formation of the personal social competence is one of the key tasks of the present-day school due to the main school documents and the guidelines for the schoolchildren education in educational institutions. It is justified that social competence is an acquired skill that can be formed and developed throughout the person’s life. The developed social competence determines the status of an individual in society and affects personal success in further professional activities.In the study, the social competence is presented as universal personal qualities, knowledge, skills, behavioural models, which are required for person’s successful socialization. The key features of social competence are: 1) recognition of the person’s value-motivational sphere; 2) readiness to solve complex tasks (state of internal psychological mobilization); 3) persistence of the manifestation of this quality. It was found that important components of social competence for today’s adolescence are: the ability to find constructive models of behaviour in various problem situations; navigate in the information space; apply the acquired theoretical knowledge in practice; the ability to work in groups, to cooperate with peers and older people; the ability to resolve productively conflict situations, based on the understanding of mental, ethnic, and cultural characteristics of different social strata of the population; the ability to conduct business electronic correspondence with various recipients, etc.Diagnostics for determining the manifestation of social competence of schoolchildren is presented, which is based on Doll’s theory of social competence. The study describes the method of forming the social competence of teenagers by means of the case method. The didactic requirements for the use of the case method in order to form the researched quality are revealed, namely: saturation of the content of the cases with a meta-subject social context, multi-problems; connection of tasks with life priorities, interests, values of teenagers; the use of cases, that involves a combination of curricular and extracurricular activities, actualization of interdisciplinary knowledge, social experience of students; use of cases based on group work; implementation of the principle of cooperation in the process of solving cases, performance by the teacher of the role of moderator.
GENERAL AND SPECIFIC FACTORS OF FUTURE ORIENTATION LINK TO AWARENESS OF MEANING IN LIFE
Authors: Koļesovs Aleksandrs
Published: July 2023

Future orientation reflects individual orientation toward personal goals, including cognitive representations of these goals and goal-directed behavior. Recent meta-analytical studies confirmed the positive effects of future orientation in various life domains. The effect of goal-orientedness in developing meaning in life still needs to be explored. This study accounted for the variability of personal goals across the life span and socialization trajectories. It focused on the relationships between a complex factorial structure of future orientation and the presence of meaning in life in emerging adults acquiring tertiary education. In total, 555 students participated in the study (mean age was 21.13, SD = 2.45, 64% females). The Individual Future Orientation Scale and Meaning in Life Questionnaire were applied for measurement. The factor analysis demonstrated that the bifactor model of future orientation includes the general factor and additional specific factors of future-oriented behavior and family-related goals. The general future orientation and future-oriented behavior positively predicted the presence of meaning in life. The emphasis on future-oriented behavior in a complex prediction is in line with the significance of the purpose in life for subjective awareness of meaningful life.

Authors: Beta Gunta , Baļķena Zane
Published: July 2023

The professional self-concept of nurses, who make up the majority of medical practitioners and who participate in the implementation of public health policy, plays an important role in job satisfaction, productivity, which leads to patient satisfaction and development of the profession. Whereas, nurse job satisfaction affects nurse's future plans related to willingness to remain in the profession. Nursing self-concept is shaped and influenced by many different factors, one of them global self-esteem. The aim of the study is to investigate the relationship between the factors forming the professional self-concept, self-esteem and willingness to remain in profession of practicing nurses. The results revealed that there are statistically significant links between some groups of socio-demographic data: age and self-esteem, level of education and self-esteem, as well as the desire to remain in the profession. Statistically significant differences have been identified between respondents' answers according to age group, education level, length of service and certificate in relation to different sub-scales of self-concept.

Authors: Veispals Martins , Gulbe Antra
Published: July 2023

Canoe sprint is a water sport (under natural conditions, it takes place on water); therefore, for the most part, research is carried out under laboratory conditions, when the load is performed on various special exercise machines (ergometers) that try to simulate natural conditions as closely as possible since doing research in natural conditions is very challenging. However, technological development and recently available specific devices allow to go forward and overcome these challenges. The aim of the research is to provide information on stroke parameters for a 200 m distance with maximum effort in natural conditions of the sport – on water, provided by the only device currently available on the market that measures the power and force applied to the stroke, and result comparison with similar research done by other authors. Dynamometry was used as the primary method to obtain indicators on power and force applied to the paddle, using a specialized device – canoe sprint power meter (One Giant Leap, Nelson, New Zealand). The average force value to the brace in a 200 m distance between all 87 braces was found to be 456.2 ± 8.7 N.

Published: July 2023

Physical activity among adults and adolescents do not meet the recommendations of WHO. Many studies focus on investigation of physical activity in students and the role of self-efficacy as important factor in predicting physical activity behaviour. Aim of the study was to determine the role of self-efficacy in physical activity in students. A literature review has been conducted to determine the self-efficacy measurements in physical activity studies and to determine factors related to self-efficacy and physical activity. Through search in the PubMed database 206 records were identified and 24 articles were included in further analysis. Thirteen studies used the General Self-Efficacy Scale [GSES] to measure self-efficacy level. Two studies considered The Exercise Self-Efficacy scale [ESES] focusing specifically on physical activity. Other studies considered different self-efficacy measurement tools including separate questions about physical activity self-efficacy as part of the questionnaire or survey used in the study. One study focused on emotional self-efficacy measures. Other factors investigated in relation to self-efficacy and physical activity were health beliefs, anxiety, depression, perceived stress, academic behaviour, academic procrastination, academic burnout, emotional intelligence, subjective well-being, Self-control, motivation and addiction, self-esteem, body image, sense of inferiority, and social support.

Authors: Azamatova Tatjana
Published: July 2023

Today, the age structure of the population of Latvia is close to the average for the European Union, but the share of senior citizens is rapidly increasing. Population aging is one of the most significant trends in demographic processes, which brings changes to all areas of society. This article analyses some risks both for seniors themselves and for society resulting from these trends, and the reasons why Latvia is falling behind in addressing these risks. The primary goal of this article is to summarise and interpret a variety of scientific publications and legal documents from a global perspective, also using methods such as monograph analysis, content analysis, descriptive statistics, and compilations of experiences and best practices. The author of the article put forward arguments in favour of the inclusion of seniors in lifelong education in Latvia, as one of the elements of social policy to reduce the negative effects of population aging. According to the author, it is necessary to promote and develop a fully lifelong learning system for seniors in Latvia.
THE PROBLEM OF ADAPTATION OF PRESCHOOL CHILDREN FOR A PRESCHOOL INSTITUTION
Authors: Romenkova Valentīna
Published: July 2023

The problem of adaptation of the child in kindergarten is still rather relevant. Despite the fact that the issue was raised by the classics of preschool pedagogy and psychology (Rubinshtein, 1957; Aksarina, 1977; Bure, 2014; Bozhovich, 1967), there are currently no answers to several important questions related to adaptation in general and to the adaptation of children. This is due to the complexity and diversity of the adaptation mechanism inherent in all living beings. The process of adaptation studied by different sciences affects different levels of adaptation to changing environmental conditions: from cells to society.In relation to a preschool child, it is important to determine the structure of the adaptation process, including such diverse phenomena as the nature of sleep, nutrition, health indicators, emotional state, as well as attitudes towards relatives and alien adults and children, the ability to actively act in a new social environment. The idea of this study grew out of the need to hierarchize the child's individual ways of responding to a new environment and to determine the sequence and timing of normative adaptation. Currently, there are very different assessments of the ability of a preschool child to be included in a social environment that is conditionally unfamiliar to him.Firstly, most authors consider the adaptation period to be extremely painful and difficult for a child, in which he is able to receive a load of difficult experiences and health disorders. The severity of the process is often estimated by the level of morbidity in children during the period of adaptation. Secondly, the course of the adaptation process itself is determined from 2 weeks to six months. Also, the specifics of children of different ages getting used to kindergarten, as well as the time when the beginning of his attending is the most favorable, has not been studied.The aim of the study is to determine the structure of the process of adaptation of children of primary preschool age in a kindergarten.

Published: July 2023

The article substantiates the problem of health-preserving competence development in teachers of preschool education: as an important task of the modern world, as a priority personal characteristic, as a component of professional training. The essence of the phenomenon of “health-preserving competence” is revealed, the following structural components are distinguished: emotional and motivational, cognitive and activity-centered. The goal of the research is to determine the conceptual foundations of the development of health-preserving competence in teachers of preschool education; data collection and processing of information to clarify problematic aspects of the phenomenon being under consideration. In the course of empirical research, the authors used the method of anonymous thematic survey (questionnaire) and its analysis. The research group consisted of: students of the 4th year of dual mode of study (who work on specialty) – 38 participants (group A); students of the 4th year of part-time mode of study who work on specialty (in preschool educational institutions) – 45 participants (group B) and students of advanced training courses – 53 participants (group C). The total number is 136 respondents. The conducted research proved that the respondents are aware of the main categories of health; are motivated and aware of the importance of health-preserving behavior, but are not sufficiently aware of modern health-preserving technologies. Therefore, the activity-centered component requires to be strengthened for the development of health-preserving competence in teachers of preschool educational institutions. Prospects for further scientific work will consist in the implementation to the system of higher education and advanced training courses for preschool teachers of the elective course “Formation of health-preserving competence in the subjects of the educational process” and determining the effectiveness of its implementation.

Published: July 2023

The purpose was to evaluate the training program, body mass composition, aerobic performance laboratory and field test results, blood hormone concentration in elite junior female roller skier in successful competition season. Methods. Totally 206 training sessions (278 training hours) were analysed during six months (from April till September). Athlete wight and body fat changes were monitored, laboratory tests on a treadmill and field tests were performed and concentration of hormones in the blood was detected. Results. A polarised training intensity distribution was observed. The highest volume of training workloads (70 training hours per month) was achieved in the last month before start of World cup season, this change corelated with change in blood testosterone levels. Heart rate decreased by 7.51% at the anaerobic threshold load intensity and by 10.1% at lower intensity loads. Peak oxygen uptake (VO2max) of 49 ml/kg/min was reached in laboratory test. Increase of lean body mass by 2.4 kg was observed. The progress in 3000m running race time was detected from 14:30 minutes in the beginning of April to 13:16 minutes in June. Conclusion. VO2max in junior elite female roller skier is low in comparison with cross-country skiers, but the training workload intensity and volume are comparable with skiers. This research shows insight in top junior level female roller-skiers physiology and training, but specific values determining the success of this athlete are still to be determined if compared to traditional cross-country skier.

Authors: Ciuciulkiene Nijole , Tandzegolskienė - Bielaglovė Ilona , Anglickienė Ruta
Published: July 2023

When discussing the assistant's emancipated participation in the educational process, it is important not to forget the pre-school teacher who often becomes a formal or informal mentor to the teaching assistant. It is the role of the mentor, his/her influence, that is one of the most important factors in the process of emancipation of the teaching assistant. Interrelationships based on support, respect, tolerance, sharing of experience and responsibility, constant help to each other, and support turn mentoring into a high-quality process that ensures emancipation. It is important that the mentor clearly defines what he/she expects from the assistant and is willing to help him/her to develop. Otherwise, it will not make sense to talk about the emancipation of the teaching assistant's professional activity. Relying on the qualitative research findings it is possible to state that a teacher assistant is supposed to provide a qualified support to an educator and a pupil in ordinary and inlusive educational process. It requires from teacher assistant vide range of competences,enabling him/her to demonstrate rationality, clear value system, professionalism, i.e. to be an emancipated personality. The process of emancipation takes place when there is the harmony among the set of emancipatory legal, philosophical, social, and educational aspects and the personal reality perception, activity and will. In order to develop the emancipation of a teacher assistant's, the competence of the mentor plays the key role, especialy his/her abilities to encourege and empower the mentee‘s independent, still community - directed solutions. Thus, the reversity of the mentoring process comes to the focus of the attention. The proof of the teacher assistant's emancipation success is considered to be the process of reverse mentoring. The qualitative content analysis of the interviews of the teaching assistants working in pre-school education institutions revealed that the emancipation of teaching assistants is observed in the answers of all informants, but the emancipation of their activities in the mentoring process is only partially ensured.

Published: July 2023

The research aimed to study the performance characteristics of male and female finalists at a 100m distance when swimming at the Latvian swimming championships in a period from 2018 to 2020 (in the 50m pool). 262 final heats got analyzed. The results of the 3 best Latvian swimmers, males=36, and females-36, at each 100m distance (freestyle, breaststroke, backstroke, and butterfly) at championships in 2018, 2019, and 2020 have been analysed. The parameters for overcoming competitive distance: competitive result in the 100-meter distance; the start reaction time; time for the 15 meters mark; speed to the 15 meters mark; the time of the turn 5 meters up to the wall and 15 meters after the turn; underwater distance and time after the start and after turning; time of “clear” swimming. The obtained results were compared to the characteristics of overcoming the same competitive distance by the finalists of the European Championship 2016. As a result of comparative analysis, statistically, significant differences were found in such parameters of competitive activity as the overall result, overcoming of starting and turning parts, and the distance covered under water after the turn and start. Statistically significant differences were not found in the reaction time to the start signal and in the speed of “clear” swimming. The comparative analysis of the performance characteristics of the European Championships finalists showed possibilities for further improvements of Latvian swimmers. The aim: is to determine the performance parameters of the Latvian best swimmers and compare them with the same parameters of the finalists of the European Championship 2016.

Published: July 2023

Lack of adherence in patients with chronic illnesses is significant burden for health care system all over the world. Therefore, it is important to find which factors do contribute to improve adherent behaviour. The aim of this study was to find out how resilience and illness denial predicts adherent behaviour in patients with chronic illnesses in primary health care.In this quantitative cross-sectional study participated 202 adults in Latvia with diagnosed chronic illness. Participants filled sociodemographic data questionnaire – gender, age, and diagnosis, Connor–Davidson Resilience Scale (CD–RISC–25, Connor Davidson, 2003), Illness Denial Questionnaire-Short Form (IDQ-SF, Rossi Ferrario et al., 2019), and Adherent behaviour questionnaire (Skaldere-Darmudasa Sudraba, 2023) – nine items measure assessing to what extent individual with chronic illness follows doctor’s or specialist’s recommendation to reduce symptoms of their chronic illness and improve health condition. Items are rated in 4 – point Likert scale. The result of this study shows a tendency that patients with chronic illness and higher resilience use less denial according to their chronic illness and use more adherent behaviour. Higher denial points to less adherent behaviour which means less following to the doctor’s and specialist’s recommendation about the intake of medication, physical activities, diet, and rest.

Published: July 2023

This study aim is to explore the relationship between coependency and coping strategies of women in relationship with an individual addicted to psychoactive substances. The study included 31 women aged 25 to 64 years (M = 42.03; SD = 9.45). Three surveys were used in the study - Socio-Demographic Data Survey; Spann-Fischer Co-dependence Scale; The Ways of Coping Scale. Spearman's correlation analysis was used to determine the liabilities, and the prediction of coping strategies / ways of indicators was performed by linear regression analysis.It was found that there is a statistically significant relationship between codependency and emotion-focused coping as strategy (strategic problem- solving, escape and avoidance, taking responsibility). Research on current coping strategies has shown that emotion-focused coping as strategy and corresponding types of stress management such as seeking social support, positive reassessment, planned problem solving and escape and avoidance are more often used.

Authors: Okuņeva Sandra
Published: July 2023

The aim of the article is to characterize the peculiarities of regional literature in a specific type of children’s literature – non-fiction books. The research focuses on the analysis of the narrative of Kurzeme, the cultural and historical region of Latvia, in the books for children by four contemporary Latvian authors – Gundega Sēja, Vitauts Ļūdēns, Valdis Klišāns and Pēteris Blūms. Using the methodology of narrative and semiotic analysis, the research has identified the main trends in the representation of Kurzeme in the creation of content and story. In the books, the writers have included information about geography, the most important natural and cultural-historical objects, historical persons and events, the peculiarity of the language, as well as certain traditions. The formation of Kurzeme narrative is dominated by a dialogue between a child and an adult, with the adult playing the role of a wise companion, as well as the technique popular in travel literature – "story within a story". The study shows the need to continue academic discussions on identifying the most appropriate term for non-fiction books in the research of Latvian children’s literature and allows to conclude that non-fiction books about Latvia and Kurzeme written by contemporary Latvian authors can be considered as important revealers of regional color.

Published: July 2023

Calcium carbonate has the potential to be used in the development of medical materials, including biomaterials. Biocomposite is composed of CaCO3 as matrix material and bioplastic from the combination of corn starch and cassava starch as reinforcement. This study aims to determine mechanical properties such as tensile strength and bending/flexural strength with varying compositions of CaCO3 and bioplastic. Characterization of the biocomposite uses Scanning Electron Microscope to observe the microstructure and composition elements of their structure. This study used 4 variations in the ratio of CaCO3 suspension: (Corn Starch + Cassava Starch). Each sample was characterized using specimen code A for composition 30:70 (w/w) percent and specimen B for composition 40:60 (w/w) percent, specimen C for composition 50:50 (w/w) percent, and specimen D for composition 60:40 (w/w) percent. Based on the results of shrinkage measurements on flexural strength specimens, specimen B has the lowest percentage value of 15±0.01 percent. The lowest tensile strength specimen is found in specimens C and D at 12±0.01 percent. The tensile test results also showed that specimen D had a higher ultimate strength value than the other specimens, which was 0.06±0.03 MPa. Microstructure characterization was carried out using scanning electron microscopy with energy-dispersive X-ray spectroscopy, which revealed the presence of Oxygen at approximately 48.39 percent mass, Carbon at approximately 30.27 percent mass, Nitrogen at approximately 11.77 percent mass, Calcium at approximately 9.57 percent mass, with Calcium being detected in the form of Calcium Carbonate (CaCO3).

Published: July 2023

The study objective is to investigate the combustion characteristics of Callophyllum inophyllum fuel in presence of a magnetic fields. To conduct the experiment, a bunsen burner was utilized, with fuel and air being dispensed via a syringe pump and compressor, both regulated by a flowmeter. The fuel and air pipes were heated to 532.15 (K) to facilitate fuel evaporation. The equivalent ratio of 0.5, 1, and 1.5 was adjusted to control air discharge and fuel. An 11,000 gausses artificial magnet was used, with N-S, N-S, N-N, and S-S being the various magnetic pole configurations. The study found that the magnetic field can enhance combustion quality by affecting the molecules involved in the combustion process. The magnetic field's force also intensifies the movement of O2, making it more energetic. As O2 travels from the North Pole to the South Pole through the combustion reaction zone, it quickens the oxidation-reduction process and curtails diffusion combustion. The red color's intensity diminishes with the magnetic field's effect, indicating this phenomenon. When a magnetic field is applied, the polarity of C.inophyllum biodiesel fuel becomes highly favorable. The triglyceride carbon chain bonds become unstable, and the van der Walls dispersion forces are weakened, which facilitates easier O2 binding to the fuel, resulting in more efficient combustion. An increase in the laminar burning velocity value can be noticed when exposed to a magnetic field.

Published: July 2023

Friction stir (FW) welding is a relatively fresh method that was created and has been continually refined and adapted to industrial applications due to its benefits. This approach for solid-state joining entails connecting the components at a temperature below their melting point and then heating them up. Clamp joint applications are widely used using external heating and hitting with high strength, but the clamped joints with the FW method are rarely done. The research studied the characteristic of clamped joints at various plate thicknesses using the FW method. In this study, 30 specimens were used in the form of a St.37 low carbon steel plate with a size of 50 mm x 100 mm and a thickness of 3 mm, 5 mm, and 9 mm, and several holes were made with a diameter of 5 mm. The plate was connected by 2 clamps, and 4 clamps then the FW method was conducted in a milling machine. The results indicate that the plates were connected well. The highest hardness value was 256.4 VHN on the FW of 9 mm plate. The microstructure is dominated by ferrite and a little pearlite phase. The largest shear force is 66.54 kN obtained at 4 clamps with a plate thickness of 9 mm, and the lowest is 13.46 kN, obtained at 2 clamps with a plate thickness of 3 mm.

Indonesia is the world's largest archipelago country with a high potential for economic development and top producer and exporter of palm oil. As an archipelago country, the most efficient cargo transportation routes are through rivers and seas. Designing and building tankers, taking into account the specifics of the operation, are relevant. The paper considers the issues of designing a tanker for the transportation of crude palm oil with a defined operation area and route. The general concept of the vessel is proposed, taking into account the restrictions on the navigation area and draft for operation in the river. Particular attention is given to the issues of strengthening the hull in terms of overall longitudinal strength, as well as the bottom and the propeller-steering complex in terms of interaction with the ground. An external structural protection (ESP) from the ground was developed, and comparative calculations of the stress-strain state of the compartment and ESP structures were performed. The effectiveness of the solution for protecting the hull from direct contact with the ground is shown, and outlined ways for the possible development of tanker projects for the conditions.

The focus of today’s machining industry is on how to maintain high productivity and low cost achieved by high tool life during the operation. Laser cutting is considered the right solution because it offers cutting speeds of up to 170000 mm/min through a non-contact process regardless of the workpiece material hardness. The aim of this study is to analyze the effect of cutting speed on the surface texture aspects namely surface roughness, kerf shape, and dross height on the stainless steel 304 plate after laser cutting. The nitrogen laser was utilized with the cutting speed of 400, 1700, and 2000 mm /min and the average roughness (Ra) was then measured using a surface roughness tester. On the other hand, the top, middle, and bottom area of the kerf surface as well as the dross height were analyzed by scanning electron microscopy (SEM). The highest Ra value was resulted at cutting speed of 2000 mm/min with 2.965 ± 0.05 μm while the lowest was at 1400 mm/min with 2.522 ± 0.16 μm. In parallel, the Ra was found to be higher when subjected gradually from the top to bottom zone. The kerf surface also proved that the top zone is dominated by the cutting zone, while the middle and bottom zone are characterized by the transition and deformation zone respectively. The width between kerf lines increased when the higher cutting speed was performed. Additionally, the larger dross height was found at the cutting speed of 1400 mm/min with 32.75 ± 5.21 μm and then degraded gradually at the higher cutting speed. The heat input and laser capability in exposing the material thickness are responsible for determining the corresponding surface texture aspects.

Fire behavior and smoke spread are influenced by various factors, including the amount and condition of combustible material, ventilation openings, and ceiling height. A high amount of combustible material in the auditorium poses a significant fire hazard, hence, efforts need to be made to minimize the risk. One approach is to use Computational Fluid Dynamic software, such as Fire Dynamics Simulator (FDS), to model fire combustion. In this research, it provides an overview of the heat release rate (HRR) of fires that occur as well as the effect of differences in ceiling height and the effect of ventilation on fire spread. This research employed Polyurethane foam, commonly used for auditorium seats, as the sample material. Furthermore, it modeled two fire points, one on the 9th floor and the other on the 10th floor, in the middle of seat rows. The development of fire in the modeling was described by the results of visualization, HRR, burning rate, and temperature rise. These results provided insight into the speed at which fire and smoke spread. The starting point on the 9th floor had the highest flame spread rate due to the ceiling jet phenomenon, where a high amount of combustible material caused the ceiling temperature to increase, producing a heat flux that could burn surrounding seats. In both scenarios, the smoke spread rapidly toward the ventilation openings. However, it was denser on the 9th floor as the starting point was farther from the ventilation openings, and the smoke on the 10th floor was less dense.

The trend of consumption of hydrocarbon fuels in Indonesia, which is increasing every year, is not accompanied by the amount of production, which is decreasing. Alternative fuels to reduce dependence on hydrocarbon fuels. One form of alternative fuel is biodiesel, which is made from corn (maize) oil. Corn oil itself, if processed, can be an option for clean and environmentally friendly energy option and that is the main objective of this research is to determine the performance of biodiesel corn oil on diesel engines. The method used in this study is an experimental method where corn oil biodiesel is tested directly on a testing machine. The data from the test results will be used to find the torque and thermal efficiency values so that the engine performance values for each fuel variation can be identified. The results of the study obtained the engine performance value, namely the highest torque was on diesel oil fuel 4.57 N.m. The highest thermal efficiency value achieved at the B30 fuel sample at a temperature of 60 °C with the thermal efficiency of 17.4 percent. With these results, it can be concluded that engine performance with corn oil fuel can be used as an alternative fuel to replace hydrocarbon fuel.
