Although international students represent around 5% of the higher education population in the United States, research on psychological factors that result in this segment’s academic success remains limited. This study sought to help fill this knowledge gap by exploring success factors that affect international students’ academic progress. Specifically, we examined psychological characteristics and learning strategies influencing these students’ achievement. Quantitative data were collected from 85 international students in the United States. Using a survey grounded in positive psychology and learning theories, we studied correlations between their character strengths, learning strategies, and academic performance. A linear regression model was used to determine the predictability of these students’ academic performance. Character strength variables correlated with academic performance and learning strategies. In addition, learning strategies correlated positively with academic performance. Multiple regression analysis revealed that both character strengths and learning strategies predicted academic performance whereas demographics did not.

Створення та експлуатація високотемпературних газоохолоджувальних реакторів (ВТГР) і газотурбінних атомних електростанцій з такими реакторами дозволить підвищити коефіцієнт корисної дії таких установок до 46 % – 50 % завдяки більш високій температурі теплоносія на виході з реактора 1000 °С – 1100 °С. Водночас ВТГР завдяки виробленій високопотенційній теплоті можна використовувати в неелектричних технологіях, як-то конверсія природнього газу, газифікація вугілля та в хімічній, металургійній і нафтопереробній промисловості. Для отримання різних технологічних продуктів зазвичай використовуються ізобарно-ізотермічні реакції. Проте, в установках з ВТГР і гелієвим теплоносієм організація процесу підведення тепла за постійної температури теплоносія неможлива, причому в разі незначної зміни температури потрібно надмірне збільшення витрат теплоносія. У статті обґрунтовано можливість підвищення ефективності використання високопотенційної частини теплоти ВТГР для газифікації твердих органічних палив завдяки організації процесу газифікації за змінної температури процесу та розвиненій системі регенерації теплоти в енерготехнологічній установці.

The study of acoustic function is growing to be important today. In the conditions of the development of an all-artificial civilization, it turns out that complementary electronic ornaments are still very dependent on the level of success with the form of the structure and composition of the room itself. The problem arises when an adjustment on one side, intended for improvement, actually shifts the ideal coordinates on the other side. For this reason, a comprehensive adjustment and correction idea should emerge as a solution, with acoustic studies as a starting point. This study tries to describe the ideal design based on investigations and observations of the actual condition of the auditorium of the National University and also tries to determine the suitable material for the room. The stages carried out in the research can be adapted to the needs of the research. This step is to get the most comprehensive results with the most effective and efficient steps. Integrated software and trial and error analysis are also part of the research method. It was found that the new design of the National University auditorium has good acoustic insulation with some adjustments that are still possible to get the ideal standardization of the room.

Hydrolytic bacteria are bacteria that play an important role in helping the digestive process of fish. This study aims to determine the hydrolytic activity of bacteria in the digestive tract of Nilem fish seen from amylolytic, proteolytic, lipolytic and cellulitic indices. The method used is exploratory and data analysis using parametric and non-parametric to explain the research data. Exploration carried out in this study included the total number of bacteria, proportion of hydrolytic bacteria, activity index of hydrolytic bacteria and molecular identification of bacteria with the best activity index. Fish were taken at random from fish farming ponds in Beji and Singasari with three fish each. The number of bacteria found an increasing pattern to the posterior intestine of fish from Beji and a pattern that varied between parts of the intestine of fish from Singasari. Hydrolytic bacteria were isolated from each part of the intestine from both locations which showed a decreasing pattern in each type of hydrolytic and intestinal tracts of fish from Singasari and varied patterns in the intestines of fish from Beji. The hydrolytic activity index showed a stable average value in each part of the intestine and the sampling location. Based on the best activity index, seven isolates were identified from three different genera, namely 1) Bacillus subtilis, 2) Enterobacter mori, Enterobacter cloacae, and 3) Aeromonas hydrophila (3), Aeromonas veronii. The bacteria obtained are classified as non-pathogenic bacteria that have potential in the field of aquaculture and normal pathogenic bacteria in the fish intestine

The learning system in vocational education is more directed to practical learning. Therefore, learning media is needed that can make students learn interactively and independently. The research aims to create an industrial automation system learning media as a learning medium for industrial automation courses. The learning media is in the form of a programmable logic controller (PLC) trainer equipped with sensors and combined with a human machine interface (HMI). PLC trainer is made because PLC devices are widely used in industrial automation systems. The PLC component has not been equipped with a display, therefore in this study PLC is combined with HMI. HMI is an interface that connects machines with humans. The Outsel PLC was chosen because the price is very affordable and developed by domestic developers. Trainers are made in a compact form, and easy to carry anywhere. Several simulations were carried out to test the function of the trainer. The test results of the PLC trainer show that the PLC trainer is able to control the process according to the logic programmed, and the HMI is able to display the ongoing process, thereby increasing the interaction between machines and humans.
