Covid – 19 has had an impact on various sectors, one of which is the education sector. Online learning or distance learning is a must. Online learning is felt by all levels of education. The teacher gives school assignments through online learning support applications or whatsappgroups. This is felt by children and parents in Sumberkolak Village, Panarukan District, Situbondo Regency. Resulting in dependence on using gadgets and reducing interest in reading. And other general knowledge. Parents feel overwhelmed in guiding their sons and daughters in doing schoolwork. They also have free time which is not accompanied by productive activities. Back to Village Community Service Program as an effort to empower the community organized by UNEJ is oriented towards optimizing children's literacy. The activity focuses on literacy and learning activists for elementary school children. This activity uses the Participatory Action Research (PAR) method. The result of this activity is the creation of a conducive and comfortable atmosphere in literacy and learning activities, as well as stimulating children's creativity and skills during the pandemic. Forming children who are active, confident, caring, and independent.

Изучено влияние микрооксидации на стадии брожения сусла и мезги на физико-химические показатели виноматериалов и концентрацию фенольных веществ. Установлено, что под действием кислорода воздуха окисляются фенольные вещества, титруемые кислоты, за счет этого снижается массовая концентрация приведенного экстракта. Между массовой концентрацией летучих кислот и кислородом выявлена прямая зависимость, при этом показатель массовой концентрации летучих кислот не превышал допустимых норм.
The influence of microoxidation at the stage of must and pulp fermentation on the physicochemical parameters of wine materials and the concentration of phenolic substances was studied. It has been established that phenolic substances, titratable acids are oxidized under the action of air oxygen, due to this, the mass concentration of the reduced extract decreases. Between the mass concentration of volatile acids and oxygen, a direct relationship was revealed, while the mass concentration of volatile acids did not exceed the permissible limits.

Published: July 2023

Introducción. El panorama nutricional en los años treinta y cuarenta giraba más en determinar los valores normales de la dieta que en el conocimiento de las formas de desnutrición dominantes y por eso se dio preferencia a la formación de dietistas y médicos dietólogos y sólo más tarde vendría la formación de nutricionistas y médicos nutriólogos. El actual estudio tratará de dar respuesta a las siguientes preguntas de investigación: ¿Con qué referencias históricas se cuentan de la ciencia nutricional? y ¿Cuáles son los inicios de formación de los nutriólogos? Desarrollo. El presente proyecto de investigación pretende poner de manifiesto el surgimiento de los nutriólogos en México, los aportes de la ciencia nutricional, problemáticas del desarrollo de la profesión, así como, estructurar una relatoría de los principales actores del área con la finalidad de comprender el desarrollo de esta disciplina. Conclusiones. La formación de Licenciados en Nutrición debe ser fortalecida hacia la vinculación con la sociedad, la cual demanda al profesional con clara evidencia de la eficacia educativa con la que ha sido formado, además de un manifiesto de alto desempeño y calidad, para que con estas herramientas pueda cumplir con las características requeridas para el empleo y abrir caminos de oportunidad laboral para las siguientes generaciones en un corto o mediano plazo.

SN 2018gk Revisited: the Photosphere, the Central Engine, and the Putative Dust
Authors: Wang 王 Tao 涛 , Wang 王 Shan-Qin 善钦 , Gan 甘 Wen-Pei 文沛 , Li 李 Long 龙 
Published: July 2023

Abstract
We perform a comprehensive study of the physical properties of SN 2018gk, which is a luminous Type IIb supernova (SN). We find that the early-time photospheric velocity varies from a larger value to a smaller one before the photosphere reaches a temperature floor. We generalize the photosphere modulus and fit the multiband light curves (LCs) of SN 2018gk. We find that the 56Ni mass model requires ∼0.90 M
⊙ of 56Ni, which is larger than the derived ejecta mass (∼0.10 M
⊙). Alternatively, we use the magnetar plus 56Ni and the fallback plus 56Ni models to fit the LCs of SN 2018gk, finding that the two models can fit the LCs. We favor the magnetar plus 56Ni model since the parameters are rather reasonable (M
ej = 1.65 M
⊙, M
Ni = 0.05 M
⊙, which is smaller than the upper limit of the 56Ni mass that can by synthesized by neutrino-powered core-collapse SNe, B = 6.52 × 1014 G, which is comparable to magnetic fields in luminous and superluminous SNe studied in the literature, and P
0 = 10.42 ms, which is comparable to initial periods for luminous SNe), while the validity of the fallback plus 56Ni model depends on the accretion efficiency (η). Therefore, we suggest that SN 2018gk might be an SN IIb powered mainly by a central engine. Finally, we confirm the near-IR excesses of the spectral energy distributions of SN 2018gk at some epochs and constrain the physical properties of the putative dust using the blackbody plus dust emission model.

Abstract
We present new 13CO (1−0), C18O (1−0), HCO+ (1−0), and H13CO+ (1−0) maps from the IRAM 30 m telescope and a spectrally resolved [C ii] 158 μm map observed with the SOFIA telescope toward the massive DR21 cloud. This traces the kinematics from low- to high-density gas in the cloud, which allows us to constrain the formation scenario of the high-mass star-forming DR21 ridge. The molecular line data reveal that the subfilaments are systematically redshifted relative to the dense ridge. We demonstrate that [C ii] unveils the surrounding CO-poor gas of the dense filaments in the DR21 cloud. We also show that this surrounding gas is organized in a flattened cloud with curved redshifted dynamics perpendicular to the ridge. The subfilaments thus form in this curved and flattened mass reservoir. A virial analysis of the different lines indicates that self-gravity should drive the evolution of the ridge and surrounding cloud. Combining all results, we propose that bending of the magnetic field, due to the interaction with a mostly atomic colliding cloud, explains the velocity field and resulting mass accretion on the ridge. This is remarkably similar to what was found for at least two nearby low-mass filaments. We tentatively propose that this scenario might be a widespread mechanism to initiate star formation in the Milky Way. However, in contrast to low-mass clouds, gravitational collapse plays a role on the parsec scale of the DR21 ridge because of the higher density. This allows more effective mass collection at the centers of collapse and should facilitate massive cluster formation.
Comparative Efficacy of Serratus Anterior Plane Block (SAPB) and Fentanyl for Postoperative Pain Management and Stress Response in Patients Undergoing Minimally Invasive Cardiac Surgery (MICS)
Authors: Saikat Sengupta , Shweta Singh , Somalia Mukherjee , Dibyendu Khan , Sushan Mukhopadhyay 
Published: July 2023

Background:
Fast-tracking plays a significant role in reducing perioperative morbidity and postoperative hospital stay by facilitating early extubation and optimal pain control. Attenuating the stress response to surgery also has a crucial function in enhancing recovery. Serratus anterior plane block (SAPB) is a recently described technique for chest wall analgesia. More data is required to find out the effectiveness of analgesia by SAPB for minimally invasive cardiac surgery (MICS).

Aim:
The study aimed to assess the efficacy and safety of ultrasound-guided SAPB compared to fentanyl for controlling post-thoracotomy pain and stress response in patients undergoing MICS.

Setting and Design:
Time framed comparative, prospective, and observational study.

Materials and Methods:
Patients undergoing MICS for coronary artery bypass grafting under general anesthesia were randomly assigned into two groups. SAPB group (Group A) patients were given 0.2% of 20 ml ropivacaine followed by catheter insertion for continuous infiltration at the end of the procedure. Fentanyl group (Group B) patients were given fentanyl infusion for postoperative analgesia. The primary outcome measured changes in visual analog scale (VAS) score (pain) and cortisol levels (for stress response) in both groups.

Results:
VAS score was significantly low in Group A when compared to Group B (P < 0.0001). Cortisol levels were also lower in the SAPB group. Hemodynamic parameters (systolic blood pressure, diastolic blood pressure, pulse rate, and oxygen saturation) were more stable in Group A with a lesser requirement of top-up analgesics.

Conclusion:
SAPB was more effective than fentanyl in managing post-thoracotomy pain after MICS. Cortisol level was lower in the group that received SAPB.
Spinal Instrumentation in the Setting of Nontuberculous Spondylodiscitis: A Prospective Analysis
Authors: Prasad Himanshu , Murthy P. V. Satyanarayana , Varma Vamsi K , Reddy A. V. Gurava 
Published: July 2023

Study Design:
This was a prospective cohort study.

Purpose:
The purpose of this study was to evaluate the efficacy of surgical treatment in nontuberculous spondylodiscitis and its effects on the functional and radiological outcomes and define a treatment algorithm.

Overview of Literature:
Most of the available literature on surgical management of nontuberculous spondylodiscitis is retrospective in nature. A prospective study analyzing functional (Oswestry Disability Index [ODI] and Visual Analog Scale [VAS]) and radiological outcomes of surgical intervention is scanty in the literature.

Materials and Methods:
A prospective analysis of 22 patients was performed who underwent surgical intervention for biopsy-proven nontuberculous spondylodiscitis. Preoperative ODI and VAS scores were compared with that at 1-year postoperative follow-up. Microbiological details of each patient were noted. Radiological evidence of healing was reported at the final 1-year follow-up.

Results:
Of 22 patients, 12 were male and the remaining were female, with a ratio of 1.2:1. The average age was 58 years. The most common region of involvement was lumbosacral followed by dorsal and cervical. All the patients underwent single-stage surgery. Microbiological studies showed growth in only 16 patients (72.7%). Staphylococcus aureus was the most common organism isolated. The mean VAS score before surgery was 8.9 which improved to 2.05 at 1-year follow-up. Similarly, the mean ODI score improved from 86.64% to 20.65% at 1-year follow-up with significant P < 0.01. Two patients needed revision for implant loosening. At the final follow-up, all patients had radiological evidence of bony consolidation.

Conclusions:
The study highlights improved outcomes with surgical intervention combined with appropriate antibiotics. With minimal complication rates, increased stability achieved following surgery alludes to good pain control and hence early mobilization. However, there is a grave concern about culture-negative spondylodiscitis which can lead to poor outcomes. Hence there is a need for further multicentre studies to strategize management of these cases.
New Composite Indexes through Factor Analysis Simplifying the Interpretation of Health-Related Quality of Life Outcomes of Surgical Adolescent Idiopathic Scoliosis Patients Completing both Scoliosis Research Society-22 and SAQ Questionnaires Longitudinally
Authors: Chau Wai-Wang , Ng Bobby Kin-Wah 
Published: July 2023

Background:
Both Scoliosis Research Society-22 (SRS-22) questionnaire (on patients’ outcome) and Scoliosis Appearance Questionnaire (SAQ) (on patients’ appearance) were well-accepted and well-validated patient-reported outcome measures. Our center administered both to severe adolescent idiopathic scoliosis (AIS) patients who underwent spinal correction. In view of a total of 14 (9 + 5) major domain scores from both questionnaires, this study attempted to develop new composite indexes using factor analysis. Materials and

Methods:
All operated AIS patients within the years 2014 and 2016 were recruited. Patients were administered both SRS-22 questionnaire and SAQ before surgery, before discharge after surgery, 1 year after surgery, and 2 years after surgery. Factor analysis without rotation was carried out and identified a total of 12 factorable domains. Factor analysis with rotation on the 12 domains was followed. Descriptive statistics and reliability analysis on the loaded factors (composite indexes) were calculated.

Results:
There were 135 severe AIS patients recruited in this study, of which 74.1% were female, and the mean age at operation was 15.97. Two factors were yielded after factor analysis (KMO = 0.633 and Bartlett’s Test of Sphericity < 0.001) with orthogonal rotation. “Trunk symmetry and health-related quality of life (HRQOL)” loaded with 2 SAQ and all 5 SRS-22 scores, and 5 SAQ scores in “Body appearance.” Reliability tests showed very strong internal consistency. Skewness and kurtosis showed data in both indexes were normally distributed.

Conclusions:
Two composite indexes “Trunk symmetry and HRQOL” and “Body appearance” were loaded after factor analysis of 12 domains from SRS-22 and SAQ. Both composite scores were reliable and normally distributed. The development of the new composite indexes “Trunk symmetry and HRQOL” and “Body appearance” simplifies result interpretation without losing the characteristics of SRS-22 and SAQ. Results can be interpreted in the same direction.

$\mathbb {H}$
, we show that, for metapletic–orthogonal dual pair over
$\mathbb {R}$
and the symplectic–orthogonal dual pair over quaternion algebra
$\mathbb {H}$
, the theta correspondence is compatible with tempered condition by directly estimating the matrix coefficients, without using the classification theorem.
