Optimization of infusion supply using the probabilistic economic order quantity (EOQ) method at Sanglah Center General Hospital
Get PDFInventory planning is important to avoid the advantages or lack of goods. Hospitals as health care providers also have a share in the stock of goods, one of which is infusion. This study aims to optimize infusion supply at Sanglah Central General Hospital using Economic Order Quantity (EOQ) method with (q, r) model. The forecasting method used in forecasting infusion requirements at Sanglah Hospital is an Autoregressive Integrated Moving Average (ARIMA) method. The results of this study indicate the amount of infusion of NaCl 0.9% 500 ml and 5% 500 ml glucose infusion which is expected to be ordered by Sanglah Hospital at the beginning of the booking period is 11,921 and 560 units. Sanglah Hospital need to re-order when the stock of infusion of NaCl 0.9% 500 ml touched the number 3,593 and 5% 500 ml glucose infusion stock touched 202 units. To anticipate the spike of demand, Sanglah Hospital is expected to provide infusion as a safety reserve of 190 units for infusion of NaCl type 0.9% 500 ml and 21 units for glucose type 5% 500 ml. The total inventory cost of the infusion to be issued by Sanglah Hospital in the planning of the infusion needs for 6 months is also obtained
Titanium dioxide (TiO2) and gel-polymer solar cells: Structures and performance evaluation
Get PDFThis research focuses on the study of semiconductor-based solar cells utilizing titanium dioxide (TiO2) and gel-polymer electrolytes. The technology for preparing the electrolytes used in these solar cells has been developed, encompassing both liquid and gel polymer electrolyte compositions. The electrochemical impedance method is employed to determine important parameters such as diffusion coefficient, mobility, and charge carrier concentration in both liquid and gel-polymer electrolytes. Experimental results are compared with theoretical calculations utilizing the electrochemical impedance spectroscopy graph. Moreover, the photon-to-current conversion efficiency of the semiconductor-based solar cells is determined using the Incident Photon to Current Conversion Efficiency (IPCE) method, covering a wavelength range of 300 nm to 900 nm

The research results emphasize that learning mathematics through experience can create an exciting and effective learning environment for second-grade students. This method helps them grasp mathematical knowledge with greater enthusiasm and provides opportunities for active participation in the learning process. However, it also poses some challenges in implementation, such as adapting to the Vietnamese educational context and ensuring that teachers have the knowledge and skills to effectively apply this method. In conclusion, this paper's research highlights the importance of applying experiential mathematics education to enhance the mathematical enthusiasm of second-grade students in Vietnam and provides theoretical foundations for its effective implementation in the Vietnamese educational environment
Application of hydroponic plants watering automations based on atmega328 microcontroller on water spinach (Pomea Aquatic Forsk)
Get PDFThe development of electronic technology in the era of globalization is very rapid. Utilization of this technology as a means to assist in agriculture, especially hydroponic plantations that are currently developing, to obtain optimal results, it is necessary to monitor the humidity and temperature conditions of the growing media. In previous research, a system was made that was able to maintain the humidity and temperature of the water following what the plant needed. The tool consists of a temperature sensor, humidity sensor, ATMega328 microcontroller, ADC and water pump. Temperature and humidity sensors function to detect temperature and humidity. The ADC functions to change the amount of voltage measured by temperature and soil moisture into a digital quantity which is then forwarded to the ATMega328 microcontroller to be processed into a digital display on the LCD. The ATMega328 microcontroller also regulates the ON and OFF of the water pump engine. The next research is to apply the tools that have been made in real terms. This research will apply the tools that have been made to the water spinach plant (Pomea Aquatic Forsk)
Bonding experiences in times of pandemic: Virtual math tutorials
Get PDFThe university bonding is very important within the integration of education and society, since it allows interaction between science and the common citizen, in addition to training future professionals with civic awareness, entering them into the social experience as workers. On the other hand, the role of virtual tutorials has come to occupy an important role within the modalities of education and an indispensable tool that allows knowledge to be built through participant leader interaction with the support of information technologies. The objective of this research is to identify the incidence of virtual math tutorials on the calcifications average of public education students in high school. One of the consequences of the COVID-19 pandemic was the fact that not all students had the tools to access their virtual classes, and those who did have access were not adapted to this modality; this led to the creation of knowledge gaps, especially in practical subjects such as mathematics. The results indicate that there was a positive impact on the grade point averages showing an increase in them, so it is concluded that it is very important to identify those subjects that merit accompaniment, and through the implementation of virtual tutors, guide students in the process teaching and learning, especially in practical subjects to improve school performance
Cognitive stimuli in the learning of mathematics in seventh grade children of basic secondary education
Get PDFThe research was based on the analysis of cognitive stimuli for learning mathematics in seventh grade students of basic secondary education of the Magaly Masson de Valle Carrera Educational Unit of the Chone canton , the results are presented through a Kendall matrix, allowing to quantify the levels of assertiveness of the variables found, the problem of mathematical learning that refers to low academic performance demands the identification of techniques and methods that allow students to be stimulated efficiently, to For this purpose, through documentary research, the stimuli applicable to the mathematical field were classified and through the analysis, 48 were identified that are closely related to the subject. In this context, the objective was to determine the most efficient for mathematical performance, the research has an exploratory and documentary approach using the use of qualitative, quantitative and analytical tools such as expert criteria, the result was the identification of the 25 most incident stimuli, recreational activities, puzzle games and riddles turned out to be determining variables, sequential and transcription stimulation occupy second place, finally the application of new technologies and ICT together with the identified stimuli offer a wide range of tools for teachers inside and outside the classroom, concludes that efficiency is relative to the experience and mystique of work with which the teacher teaches his students, however the application of the stimuli defined in this study contribute significantly to academic performanc
Development of skills in the mathematical logic field
Get PDFThe study aimed to determine the development of mathematical logic skills and abilities of the Initial sublevel of the Jacinto Educational Unit Santos Verduga 2021-2022, which raised as a problem the causes that prevent the development of mathematical logic skills, due to the lack of stimulation of parents towards their children at an early age, due to ignorance and disorientation of the teacher towards parents of how to help them. Logical-mathematical knowledge is what the child builds by relating the experiences obtained in the manipulation of objects. The methodology used was based on a descriptive-explanatory level of research with a quantitative approach due to the relationship of the variable with the object of study, using the inductive-deductive, analytical, synthetic, and statistical method. applying various data collection instruments such as: the survey to teachers, questionnaires to parents and observation of students. It was obtained as a result that the boys and girls of the educational unit have little development in mathematical logic skills, which can trigger difficulties in the appropriation of mathematical concepts
