An Assessment of the Correlation Between Teacher- Student Racial Congruence and Student Mathematics Performance in Black, Hispanic, and White Teachers and Students
Authors: Kataria Rohit 
Published: May 2023

Previous research has well demonstrated that there is a statistically significant gap between the academic performance of Black and Hispanic students and the academic performance of White students. However, the factors contributing to this phenomenonvare not clearly defined. By analyzing data from the Department of Education’s National High School Longitudinal Study of 2009, this study determines if teacher-student racial/ethnic congruence is associated with a student’s mathematics performance for Black, Hispanic, and White students and teachers. After initial calculations suggested differences in standardized mathematics performance among student groups based on the race/ethnicity of the student’s math teacher, several linear regressions that controlled for sex, income, and guardian education level revealed the statistical insignificance of these relationships. Although this study shows that teacher-student racial/ethnic congruence is not associated with the present academic performance disparities in American society, further research is warranted as to what factors are and are not associated with this observed phenomenon.
Medicine as a Tool of Empire: How Medical Developments Advanced European Imperialism in the Late Nineteenth and Early Twentieth Centuries
Authors: Ratangee Brina 
Published: May 2023

Significant research and historical analyses have been performed regarding the driving factors of imperialism in the yearspreceding World War I, but the role of medicine in enabling imperialism during the late nineteenth and early twentiethcenturies has been comparatively understudied. Additionally, existing analyses focus mainly on specific imperial-era medicaland public health measures, such as the development of quinine for malaria or the establishment of schools for tropical medicine. This analysis synthesizes much of the research that has been done on medical developments during the Age of Imperialism to explore the various ways in which disease and medicine intersected with colonial rule. Primary sources and secondary historiographical perspectives suggest that medical developments advanced imperialism by both facilitating colonial arrival and cementing European colonial power in developing regions. Furthermore, they support the assertion that developments in medical technologies and infrastructures were more important than economic, military, political, humanitarian, and religious motives in advancing imperialism.

Abstract. Traditional shrimp farming systems are generally susceptible to disease outbreaks, resulting in low productivity. However, the application of farming technology can reduce these risks. This study aims to calculate the production and examine pond water quality in vannamei shrimp culture by applying semi-intensive, intensive, and super-intensive farming systems through direct measurements and field observations. The results showed that the highest productivity was produced in super-intensive ponds at 5.4 kg/m2, in intensive systems at 2,325 kg/m2, and in semi-intensive farming systems at 0.575 kg/m2. The semi-intensive salinity ranged from 30.8 ppt to 35.1 ppt, the super-intensive salinity ranged from 29.2 to 31.9 ppt, and the semi-intensive salinity ranged from 30.9 to 34.2 ppt. The temperature ranges from 26.7 to 28.5°C for semi-intensive culture, 25.9 to 28°C for super-intensive farming, and 27.8 to 29.3°C for semi-intensive farming. The pH in the semi-intensive farming system is 7.9-8.3, the super-intensive pH is 7.7-8.6, and the semi-intensive system is at pH 7.7-8.2. Dissolved oxygen levels range from 4.0 to 5.9 ppm in intensive shrimp farming, 3.0 to 3.6 ppm in super-intensive shrimp farming, and 3.2 to 4.0 ppm in semi-intensive shrimp farming. Therefore, it can be concluded that the higher the farming technology applied, the higher the ponds' productivity. Meanwhile, differences in farming systems do not impact changes in water quality.Abstrak. Budidaya udang sistem tradisional mudah terjadi penyebaran penyakit dan produksinya rendah.

Sigmoid volvulus is a condition in which the torsion of the sigmoid colon around its mesenteric axis leads to acute colonic obstruction that is not timely and properly treated, leading to life-threatening and morbid complications such as bowel ischemia, gangrene and perforation. The aim of the study is to analyze the risk factor of SV, clinical signs and symptoms, treatment, complications and outcomes when it presents as a surgical emergency in a tribal area in central India. This is a prospective, single-center, cohort study of 24 patients presenting to the government with features of SV. medical college Shahdol [tribal area of ​​central India] from June 2022 to November 2022. All data formulated in frequency charts. We develop a prediction model for the high incidence of SV, its presentation and treatment in patients from the trunk region. 21 patients (87.5%) were male and 3 patients (12.5%) were female. The age of the patients varied between 30-80 years, most of them between 50-70 years. The main risk factors were [1] old age, [2] male gender, [3] rural residence, [4] low socioeconomic status, [5] pure vegetarian diet, [6] abuse [mc-alcohol], [7] chronic constipation, [8] chronic pain medication user [9] associated comorbidity [mc-hypertension] [10] high fiber diet, have a higher chance of this. The most common symptoms were absolute constipation and generalized abdominal distension followed by abdominal pain. The most common symptoms were tenderness followed by tachycardia and then fever. All patients were examined by clinical symptoms, plain X-ray of the upright abdomen and blood tests. Vomiting, the most common postoperative complication, followed paralytic ileus. Among the patients, 6 had distended gangrenous SV, 15 patients were found to have distended non-gangrenous, and 3 patients had perforated gangrenous sigmoid colon volvulus. Mostly treated with sigmoidectomy with stoma followed by resection with colorectal anastomosis with flatus bypass. Most patients were discharged, only 3 [12.8%] patients died.SV predominates in older men. Most patients with SV have a history of alcohol abuse, a high-fiber diet, and low socioeconomic status.

Objectives: The current study aimed to assess the cyclic fatigue resistance of two nickel-titanium (NiTi) rotary files after immersion in 5% sodium hypochlorite (NaOCl) and Deconex.
Materials and Methods: In this in vitro study, 90 new M3 Pro Gold size 25.06 and size F2 SP1 files were tested. Forty-five files of the same brand were randomly distributed into three groups (n=15) and submitted to the following immersion protocol for 5 minutes at room temperature: no immersion (control group), immersion in 5% NaOCl, and immersion in Deconex. The cyclic fatigue resistance of the files was then measured in a custom-made tester. Two-way ANOVA was applied to compare the cyclic fatigue resistance of SP1 and M3 NiTi rotary files based on the type of disinfectant solution. Post-hoc LSD test was used for pairwise comparisons and P<0.05 was considered significant.
Results: Two-way ANOVA indicated a significant difference in the mean cyclic fatigue resistance of M3 and SP1 NiTi rotary files. The M3 files immersed in NaOCL displayed the lowest and the SP1 files immersed in Deconex showed the maximum cyclic fatigue resistance. The effect of type of disinfectant solution (P<0.001) and type of NiTi file (P<0.001) on cyclic fatigue resistance was statistically significant.
Conclusions: The cyclic fatigue resistance of NiTi rotary instruments can be affected by immersion in disinfectants, and the specific type of file and disinfectant used will ultimately determine the extent of this impact.

Introduction: Due to the increasing prevalence of COVID-19 and its effects on the sense of taste and smell, we analyzed Blood electrolyte levels and biomarkers in COVID-19 patients who have a sign of anosmia and ageusia in Zanjan, Iran, and its relationship with biochemical blood indicators.
Method: The retrospective study included all hospitalized patients with confirmed COVID-19. We registered laboratory parameters. A questionnaire that validity and reliability have already been confirmed was used to assess anosmia and ageusia. Statistical analysis was evaluated using a bivariate Bayesian logistic regression in the binomial distribution.
Results: A total of 450 COVID-19 patients completed the study (221 females). The mean age of the patients was 56.36±17.34 years. 31.8% and 24.9% of patients reported anosmia and ageusia. There was no significant relationship between anosmia and ageusia with age, gender, place of hospitalization, marriage status, duration of hospitalization, and CT scan (p<0.05). The Male's platelet was 18.72 lower than the female’s (p=0.002). Male's C-reactive protein was 4.96 units higher than female(p=0.002). In hospitalized persons for less than four days and people under 39 years of age, CRP levels were lower (P=0.001, P=0.019 respectively). The Levels of lactate dehydrogenase in patients with anosmia were 51.72 units less than in patients without anosmia (p=0.010).
Conclusion: These results suggest that anosmia and ageusia are prevalent symptoms in Iranian COVID-19 patients. More information on serum biomarkers would help us to establish a greater degree of accuracy on this matter.
Enacting a Task-Based Language Teaching Curriculum in Indonesian non-Formal Education (INFE): Rationales and Challenges
Authors: Marzuki M. Junaidi 
Published: May 2023

Tasks-Based Language Teaching (TBLT) has successfully attracted attention of a second (L2)/foreign language (FL) practitioners, researchers, trainers as well as curriculum developer. Much of the research conducted, however, has mainly focused in formal educational settings, and less research carried out in non-formal educational context. The intent of this paper, therefore, is to advocate the notion of enacting TBLT curriculum in General English (GE) program in the pursuit of increasing students’ language communicative competence at Institute of English Course and Training (IECT), one of Indonesian Non-Formal Educations (INFE) in East Lombok Regency of Nusa Tenggara Barat Province, Indonesia. The rationales and challenges of enactment will be provided, and mainly will be based on my experience as a founder of non-formal language centers, as well as a reflexive practitioner. The advocacy should not solely confine to my home regency, East Lombok, but also to language center of INFE that runs GE in Nusa Tenggara Province.

<p>Desa Kebakalan adalah salah satu daerah di Kabupaten Kebumen secara geografis terletak di daerah perbukitan. Desa ini memerlukan perhatian khusus dalam peningkatan sarana dan prasarana, terutama adalah untuk penerangan jalan umum (PJU) dan ruang publik, dikarenakan minimnya penerangan jalan umum karena masih ada sebagian wilayah yang belum dilalui oleh jaringan listrik. Ketidaktersediaan jaringan listrik ini memberikan ekses negatif dimana menurut sumber data dari TKP2KDes tahun 2020 jumlah keluarga yang tergolong miskin mencapai 526 atau sekitar 45 % yang tersebar di 3 Rukun Warga (RW). Harapan lainnya lampu PJU juga akan memberikan kenyamanan dan keselamatan warga, menghidupkan kegiatan ekonomi dan menghindari timbulnya kriminalitas jalanan sesudah hari gelap. Program pengabdian masyarakat melalui Program Teknologi yang Didesimasikan ke Masyarakat (PTDM) dilakukan untuk menjadi inisiasi program pemberdayaan masyarakat selanjutnya dilakukan melalui proses survey kebutuhan masyarakat, survey lapangan dan pasar, diskusi dengan mitra, pelaksanaan, evaluasi serta diskusi keberlanjutan program. Dari hasil kegiatan pengabdian telah berhasil diperoleh model lampu penerangan jalan umum yang sesuai dengan kebutuhan warga, sudah diperoleh desain tiang lampu yang sesuai dengan identitas desa, sudah terpasang sebanyak 20 titik lampu yang tersebar di semua RW yang membutuhkan dan sudah diperoleh data untuk pengajuan dan program pengabdian selanjutnya.

Published: May 2023

Background:
Multiligament knee injury (MLKI) with associated extensor mechanism (EM) involvement is a rare injury, with limited evidence to guide optimal treatment. The purpose of this study was to identify areas of consensus among a group of international experts regarding the treatment of patients with MLKI and concomitant EM injury.

Methods:
Utilizing a classic Delphi technique, an international group of 46 surgeons from 6 continents with expertise in MLKI undertook 3 rounds of online surveys. Participants were presented with clinical scenarios involving EM disruption in association with MLKI, classified using the Schenck Knee-Dislocation (KD) Classification. Positive consensus was defined as ≥70% agreement with responses of either “strongly agree” or “agree,” and negative consensus was defined as ≥70% agreement with “strongly disagree” or “disagree.”

Results:
There was a 100% response rate for rounds 1 and 2 and a 96% response rate for round 3. There was strong positive consensus (87%) that an EM injury in combination with MLKI significantly alters the treatment algorithm. For an EM injury in conjunction with a KD2, KD3M, or KD3L injury, there was positive consensus to repair the EM injury only and negative consensus regarding performing concurrent ligamentous reconstruction at the time of initial surgery.

Conclusions:
In the setting of bicruciate MLKI, there was overall agreement on the significant impact of EM injury on the treatment algorithm. We therefore recommend that the Schenck KD Classification be updated with the addition of the modifier suffix “-EM” to highlight this impact. Treatment of the EM injury was judged to have the highest priority, and there was consensus to treat the EM injury only. However, given the lack of clinical outcome data, treatment decisions need to be made on a case-by-case basis with consideration of the numerous clinical factors that are encountered.

Clinical Relevance:
Little clinical evidence exists to guide the surgeon on the management of EM injury in the setting of a multiligament injured or dislocated knee. This survey highlights the impact that EM injury has on the treatment algorithm and provides some guidance for management until a further large case series or prospective studies are undertaken.
Spatial Data Assimilation and Risk Forecasting in Geologic CO2 Sequestration
Authors: Chen Bailian , Kang Qinjun , Pawar Rajesh J. 
Published: May 2023

Abstract
Geologic uncertainty usually leads to large uncertainty in the predictions of risk-related system properties and/or risk metrics (e.g., CO2 plumes and CO2/brine leakage rates) at a geologic CO2 storage site. Different type of data, e.g., point measurements from monitoring wells and spatial data from 4D seismic surveys, can be leveraged or assimilated to reduce the risk predictions. In this work, we develop a novel framework for spatial data assimilation and risk forecasting. Under the U.S. Department of Energy's National Risk Assessment Partnership (NRAP), we have developed a framework using an ensemble-based data assimilation approach called ES-MDA-GEO for spatial data assimilation and forecasting. In particular, we took CO2 saturation maps (can be interpreted from 4D seismic surveys) as inputs for spatial data assimilation. Three seismic surveys at years 1, 3 and 5 were considered in this study. Accordingly, three saturation maps were generated for data assimilation. The impact of level of data noise was also investigated in this work. Our results show increased similarity between the updated reservoir models and the "ground-truth" model with the increased number of seismic surveys. Predictive accuracy in CO2 saturation plume increases with the increased number of seismic surveys as well. We also observed that with the increase of the level of data noise from 1% to 10%, the difference between the updated models and the ground truth does not increase significantly. Similar observation was made for the prediction of CO2 plume distribution at the end of post CO2 injection period by increasing the data noise. Our study results also indicate that comparatively spatial data carry more value than point measurements from monitoring wells to reduce the uncertainty in the risk predictions.
