Kreatifitas Guru Mendesain Pembelajaran: Kajian Fenomenologi Dalam Pembelajaran Daring Pada Masa Pandemi Covid-19

Learning during the Covid-19 pandemic was designed by teachers who were often considered abnormal because it was different from learning activities during normal times. Both teachers and students experience obstacles in carrying out learning, both offline and online. For this reason, this study aims to describe how the learning phenomenon during the Covid-19 pandemic in Bangkalan Madura, and how the teacher's creativity is in designing learning. Data collection was carried out through questionnaires, interviews, and observation of learning design documents carried out during the pandemic. This study used a qualitative descriptive analysis of Miles and Huberman. The results of this study indicate that there are two different phenomena of changes in the form of learning implementation and creative learning designs carried out by two teachers from different schools in Bangkalan Madura. Changes in form occur referring to the accessibility aspect of the implementation of learning by paying attention to the obstacles faced by both teachers and students. This change in form provides teachers with literacy challenges, both digital literacy, and creativity. This research proves that teachers' creativity in realizing 21st-century learning in this pandemic has become increasingly sharp. Two phenomena of changing the form of learning implementation and the creativity of learning designs carried out by teachers during this pandemic can be examples or references for other teachers in carrying out blended learning or online learning during the pandemic

Synthesis of Gd-dtpa-folat for Magnetic Resonance Imaging Contrast Agent and Characterization by Using 153gd-dtpa-folate Radioactive

Contrast agent was used to clarify the image of the organ that is difficult to distinguish by MRI (Magnetic Resonance Imaging) techniques, particularly in soft tissues of the central nervous system, liver, digestive system, lymphatic system, breast, cardiovascular and pulmonary systems. One of the commonly used contrast agents in hospitals is Gadolinium-DieThylenetriamine Pentaacetic Acid (Gd-DTPA). Gd-DTPA is non specific contrast agent, therefore it has led to develop a contrast agent that is able to achieve the target without defect to the surrounding normal cells. Folic acid as a safe vitamin, inexpensive, specific and also can be used as drug delivery. This study was conducted in the development of targeted MRI contrast agent based of folic acid as a carrier by using Gd metal and DTPA ligand. Since Gd-DTPA-folate is non-active compounds, the characterization of Gd-DTPA-folate was performed using 153Gd-DTPA-folate, which was obtained by reacting DTPA-folate with radionuclides 153Gd. The results of optimization reactions of 153Gd-DTPA-folate was obtained at the mole ratio of DTPA-folate to Gd metal 20:1 and produced the radiochemical purity more than 90%. Identification of the non active product Gd-DTPA-folate was performed using an Fourier Transform- Infra Red (FT-IR) Spectrophotometer and Thin Layer Chromatography (TLC) compared with folic acid and EDA-folate. The results indicated that the product is Gd-DTPA-folate

Comparison of C4.5 and Naive Bayes for Predicting Student Graduation Using Machine Learning Algorithms

Student graduation is a very important element for universities because it relates to college accreditation assessment. One of them is at the Faculty of Engineering Nurul Jadid University, which has problems completing the study period within a predetermined time. So that it can be detrimental because accreditation is less than optimal, and the number of active students makes it less ideal in teaching and learning activities. This study aimed to compare the level of accuracy using the C4.5 algorithm and Naïve Bayes method in predicting graduation on time. The C4.5 and Naïve Bayes algorithms are one of the methods in the algorithm for classifying. Tests were carried out using the C4.5 and Naïve Bayes algorithms using Google Colab with Python programming language, then validated using 10-fold cross-validation. The results of this study indicate that the Naïve Bayes method has a higher accuracy value with an accuracy rate of 96.12%, while the C4.5 algorithm method is 93.82%

An Analysis of Multi-Processors Using Ischium

Unified optimal models have led to many extensive advances, including rasterization and robots. After years of important research into the Turing machine, we disconfirm the emulation of interrupts, demonstrates the private importance of complexity theory. Ischium, our new heuristic for the transistor, is the solution to all of these challenges

An Overview of Sky Brightness Surrounding Timau National Observatory (TNO), Indonesia

This study aims to analyze skylight conditions surrounding the newly constructed Timau National Observatory (TNO) in Kupang, Indonesia. The analysis was carried out with the primary reason of determining the initial conditions and surroundings of the area, thereby providing valuable information for future observers who will be using the facility. To achieve the stated aim, the sky brightness in the study area was measured in units of magnitudes per square arcsecond (mpsas) at a 20-kilometer radius. Furthermore, numerous observations were conducted at 32 distinct observation points using Sky Quality Meter (SQM) LU-DL (SQM-LU-DL), which was directed towards the zenith. The results obtained from these observations were subsequently analyzed using Surfer software with the primary aim of determining sky brightness in the study area. The analysis showed variations in sky quality in a 20 km radius, ranging from 21.64 to 20.37 magnitudes per square arcsecond (mpsas). The measurements showed that sky quality fell between the categories of great dark and semi-suburban transitional skies. However, it was important to comprehend that recent investigations had identified bright areas surrounding the observatory area, capable of diminishing the visual quality of sky if left unaddressed

Patient factors that affect pre-operative patient-reported outcomes in women undergoing breast cancer surgery

Background/Objective: Understanding the impact of patient, disease, and treatment factors on pre‐ operative patient reported outcomes (PROs) is important to guide surgical decision‐making with breast cancer. Methods: This prospective cohort study evaluates PROs in women undergoing breast cancer treatment at a metropolitan health care system. New cases undergo tumor board discussion and same‐day consultations with various specialties. Women choose to complete pre‐ and post‐operative Breast‐Q© Breast‐conserving surgery (BCS), mastectomy (M), or reconstruction ® modules and demographic surveys. Individual associations to pre‐operative Breast‐Q survey scores were assessed using linear regression models (1 for each Breast‐Q survey type). Variables significant for at least 1 survey were included in multiple linear regression models. Results: A total of 375 women completed the pre‐operative surveys (BCS=244, M=39, BR=92). Procedure choice, laterality, race, marital status, employment, prior breast cancer, neoadjuvant chemotherapy, or history of radiation or chemotherapy did not impact PROs. Breast satisfaction decreased with higher BMI (est=‐0.367, p=0.045) and Stage II disease (est=‐11.011 (vs. Stage 0), p=0.008). Lower psychosocial score was associated with younger age (est=0.271, p=0.002), higher BMI (est=‐0.367, p=0.014), and income \u3c$35k (est=0.172 (vs. 35k+), p=0.016). Similarly, lower physical well‐being of the chest was associated with younger age (est=0.207, p=0.011), higher BMI (est=‐0.285, p=0.039), and income \u3c$35k (est=0.218 (vs. 35k+, p=0.039). Sexual well‐being decreased with higher BMI (est=‐0.545, p=0.004) and income \u3c$35k (est=0.135 (vs. 35k+), p=0.016). Conclusions: While factors such as age, BMI, and stage of disease are difficult to change prior to surgery, patients with lower income may need special interventions to assist them through the treatment process
