Unsettled Issues Regarding the Certification of Electric Aircraft
Authors:   AMD Consulting, Mracek Dietrich Anna , Rajamani Ravi ,   drR2 Consulting
Published: June 2021

The aerospace industry is beginning to grapple with the reality of certifying electric aircraft (EA), signaling the maturing of the field. Many players are ramping up their activities to respond to imminent technical, safety, and regulatory requirements. While there are gaps in EA knowledge as well as the processes for certifying them, some leading standards development organizations (SDOs) such as SAE International, ASTM International, and RTCA—ably supported by representatives from regulatory agencies—are stepping in to address many of these issues. Of special importance are the new rule changes in the normal category (14 CFR Part 23, Amendment 64) that shift from a prescriptive philosophy to “performance-based rules.” Regarding system knowledge, there has been a trend in the use electrical energy to power systems that have long employed mechanical hydraulics. In the new EA paradigm, these components will be employed at criticality levels not previously witnessed in conventional aircraft, calling for a specific set of certification demands. Unsettled Issues Regarding the Certification of Electric Aircraft tackles the certification challenges faced by EA manufacturers in both the small (normal) and large (transport) categories, addressing technical, business, and process issues.

Background: Studies have shown that ICT adoption contributes to productivity and economic growth. It is therefore important that health workers have knowledge in ICT to ensure adoption and uptake of ICT tools to enable efficient health delivery.Objective: To determine the knowledge and use of ICT among students of the College of Health Sciences at the University of Ghana.Methods: This was a cross-sectional study conducted among students in all the five Schools of the College of Health Sciences at the University of Ghana. A total of 773 students were sampled from the Schools. Sampling proportionate to size was then used to determine the sample sizes required for each school, academic programme and level of programme. Simple random sampling was subsequently used to select students from each stratum.Results: Computer knowledge was high among students at almost 99%. About 83% owned computers (p < 0.001) and self-rated computer knowledge was also 87 % (p <0.001). Usage was mostly for studying at 93% (p< 0.001). Conclusions: This study shows students have adequate knowledge and use of computers. It brings about an opportunity to introduce ICT in healthcare delivery to them. This will ensure their adequate preparedness to embrace new ways of delivering care to improve service delivery.Funding: Africa Build Project, Grant Number: FP7-266474Keywords: ICT, health professionals, knowledge, students
Approach to an obstetric prognosis scale: The modified SOFA scale
Authors: Blanco Esquivel Lourdes A , Urbina Jorge Macia , Zerón Hugo Mendieta
Published: June 2021

Background: Severe obstetric morbidity constitutes a serious problem worldwide; however, an effective obstetrical prognosis scale is still missing.Objective: To propose a modified Sequential Organ Failure Assessment Score (SOFA) score based on time before reaching specialized medical attention.Method: This was an ambispective, descriptive study, including all women treated at the Obstetrical Intensive Care Unit (OICU) of the “Mónica Pretelini Sáenz” Maternal-Perinatal Hospital (HMPMPS), Toluca, Mexico, from June 2009 to June 2013. The patient’s SOFA score and clinical evolution were registered daily. A modified obstetrical SOFA scale was constructed adjusting the value of 180 instead of 200 in the punctuation column of 3 for the PaO2/FiO2 ratio and adding a file of disease evolution time with sepsis prior to reaching specialized medical attention.Results: Two hundred thirty two patients, with an average age (SD) of 26.42 (±7.54) years, mean gestational age of 33 (±7.5) weeks were included in the study; 118 suffered from pre-eclampsia, 56 obstetric haemorrhages, 41 eclampsia (25 preceded by pre-eclampsia) and 23, sepsis. ROC curves showed a higher area under the curve (AUC) for the modified SOFA (0.868; p<0.001) than SOFA (0.796; p=0.003), in the prediction of maternal mortality.Conclusions: The SOFA score, taking into account a lower value for the Kirby index and a threshold time of 12-h with sepsis before getting specialized medical attention, shows a good predictive value for maternal death and could be considered for evaluating the severity of complicated obstetrical patients.Funding: None declaredKeywords: Intensive Care Units, maternal mortality, Sequential Organ Failure

Authors: Anyanechi Charles E , Osunde Otasowie D , Saheeb Birch D
Published: June 2021

Objective: To analyze cases of compound, unfavorable and non-comminuted mandibular angle fractures treated by trans-osseous wiring, presenting postoperative complications, in a low resource center.Materials and methods: This was a 13-year retrospective study of 1,324 fractures in 1,317 subjects. The predictor variables were age, gender, aetiology, time lag between injury and treatment, and concomitant mandibular and midfacial fractures. The outcome variable was the development of complication(s) after treatment. Descriptive and bivariate statistics were computed with EPI INFO 7 version software, and the P value was set at 0.05.Results: The sample size was composed of 63/1317 (4.8%) of patients with complications. There were 48 males and 15 females with male: female ratio of 3.2:1. The age of the patients ranged from 21 to 62 years (mean 37.4± 5.6 years). The test of significance showed statistically significant association between complications of mandibular angle fractures and increasing age (P<0.002), male gender (P<0.001), road traffic accident (P<0.001), longer time lag between injury and treatment of fractures (P<0.000), and concomitant mandibular fractures (P<0.000). Deranged occlusion (n=19, 28.8%) and limited mouth opening <35mm (n=16, 24.2%) were the common complications. The complications were successfully treated during follow-up.Conclusion: The use of trans-osseous wire osteosynthesis gave good results, and can still be useful in centres that are less well equipped and where access to rigid internal fixation with mini plates is either limited or unavailable. Funding: Self-fundedKeywords: Mandible, angle, fracture, trans-osseous wiring, complications

Published: June 2021

Objectives: We tried to investigate the effects of lunar phase on Shock Wave Lithotripsy (SWL) related pain. In addition, correlation of various clinical parameters with the pain perception during SWL procedure, were also investigated.Methods: A total of 378 patients who underwent first SWL sessions for renal or ureteral stones were prospectively enrolled in the study. The degree of pain perception during the procedure was evaluated with 10-point visual analog scale (VAS) and pain questionnaires. The date of SWL was allocated to dates and times of lunar phases as: newmoon, waxing crescent, first quarter, waxing gibbus, fullmoon, waning gibbus, last quarter and waning gibbus.Results: Mean VAS scores in first quarter (2,41±1,06) were significantly lower when compared to mean VAS scores in waning crescent (3,58±1,83) and waning gibbus (3,42±1,98) (p=0,005 and 0,041, respectively). No statistically significant differences were observed when other lunar phases were compared between each other. Mean painscores were not affected from gender, age, body mass index (BMI) and stone characteristics (stone laterality, burden and location).Conclusions: SWL procedure performed in first quarter of the lunar phase may become less painful. To the best of our knowledge, this is the first study which evaluated the effect of lunar phase on post-SWL pain outcome. Thus, additional randomized studies with larger series may be more informative.Keywords: lunar phase, lithotripsy, pain, predictive factors, urinary stones
Two cases of Pentalogy of Cantrell diagnosed antenatally at Korle Bu Teaching Hospital, Accra
Authors: Swarray-Deen Alim , Seffah Joseph D , Antwi-Agyei Deliverance A
Published: June 2021

Pentalogy of Cantrell is a rare congenital malformation syndrome that may be associated with other congenital anomalies. The syndrome is said to affect males and females in equal numbers and the prognosis is generally poor. We report two cases of Cantrell’s Pentalogy diagnosed antenatally at the Korle Bu teaching Hospital. The 2 cases described in this report demonstrate the complete and incomplete variant of the syndrome. The cases were referred as an omphalocoele and a detailed anomaly scan confirmed the diagnosis of Pentalogy of Cantrell. Both cases were females and neither survived beyond 24 hours. Although this condition is associated with a poor prognosis, there have been some reported cases of survival in the literature. Thus, accurate prenatal diagnosis and a multidisciplinary approach to the management may offer improved outcomes.Keywords: Foetal Anomaly, Ventral wall defect, Obstetric ultrasound, Prenatal diagnosis, Thoraco-abdominalsyndrome

Weak Keys in Reduced AEGIS and Tiaoxin
Authors: Liu Fukang , Isobe Takanori , Meier Willi , Sakamoto Kosei
Published: June 2021

AEGIS-128 and Tiaoxin-346 (Tiaoxin for short) are two AES-based primitives submitted to the CAESAR competition. Among them, AEGIS-128 has been selected in the final portfolio for high-performance applications, while Tiaoxin is a third-round candidate. Although both primitives adopt a stream cipher based design, they are quite different from the well-known bit-oriented stream ciphers like Trivium and the Grain family. Their common feature consists in the round update function, where the state is divided into several 128-bit words and each word has the option to pass through an AES round or not. During the 6-year CAESAR competition, it is surprising that for both primitives there is no third-party cryptanalysis of the initialization phase. Due to the similarities in both primitives, we are motivated to investigate whether there is a common way to evaluate the security of their initialization phases. Our technical contribution is to write the expressions of the internal states in terms of the nonce and the key by treating a 128-bit word as a unit and then carefully study how to simplify these expressions by adding proper conditions. As a result, we find that there are several groups of weak keys with 296 keys each in 5-round AEGIS-128 and 8-round Tiaoxin, which allows us to construct integral distinguishers with time complexity 232 and data complexity 232. Based on the distinguisher, the time complexity to recover the weak key is 272 for 5-round AEGIS-128. However, the weak key recovery attack on 8-round Tiaoxin will require the usage of a weak constant occurring with probability 2−32. All the attacks reach half of the total number of initialization rounds. We expect that this work can advance the understanding of the designs similar to AEGIS and Tiaoxin.
Automated Search Oriented to Key Recovery on Ciphers with Linear Key Schedule

Published: June 2021

Automatic modelling to search distinguishers with high probability covering as many rounds as possible, such as MILP, SAT/SMT, CP models, has become a very popular cryptanalysis topic today. In those models, the optimizing objective is usually the probability or the number of rounds of the distinguishers. If we want to recover the secret key for a round-reduced block cipher, there are usually two phases, i.e., finding an efficient distinguisher and performing key-recovery attack by extending several rounds before and after the distinguisher. The total number of attacked rounds is not only related to the chosen distinguisher, but also to the extended rounds before and after the distinguisher. In this paper, we try to combine the two phases in a uniform automatic model.Concretely, we apply this idea to automate the related-key rectangle attacks on SKINNY and ForkSkinny. We propose some new distinguishers with advantage to perform key-recovery attacks. Our key-recovery attacks on a few versions of round-reduced SKINNY and ForkSkinny cover 1 to 2 more rounds than the best previous attacks.

Relevance of Moral Principles in Jaina Philosophy: In Present Situation
Authors:   Associate Professor, Dept. of Philosophy D. S. College, Katihar, Rani Dr. Veena
Published: June 2021

The Moral principles of Jaina Philosophy indicate that this philosophy represents the practical application of an ideal life. The systematic moral discipline laid down by Jaina Philosophy lights up one person from the common level and makes him enabled of knowing and practicing truth through a highly moral and spiritual course of conduct. Jainism is said to be based on the three basic principles known as ‘Ratnatraye’ or the three Gems ( right belief, right knowledge and right conduct). Jainism is a system that has taken up the path of non-violence for ages and is still applying this ideal to mankind’s practical life in the contemporary age. It lays emphasis on the practice of the principles of non-violence in every individual from which it is evident that its ultimate goal is the well – being of mankind and social improvement. In this paper, an attempt is made to analyse how the ethical principles of Jaina Philosophy is relevant to present time situation in maintaining peace and harmony in the society. There is no denying the fact India is a Lord of spiritualism. The Upnishada, the Gita, the Bhudhist Tripitakas and the Jaina Agams – all these regard spiritual realization as the highest object of human life. In these works, ethical utterances are intertwined with spiritual expressions. Ethical knowledge is the base of humanity. It is the root of human value. Today, when the mind set of people has been polluted of illegal activities, the question– what is morality is surprisingly found to be forgotten by the society. The human race has remarkably become crooked, engulfed in unlawful deeds like injustice, enmity, malice etc. Here comes the relevance of the discussion on ethical knowledge most befittingly during this time in the world. The endless treasure of vast knowledge that had once been designed by the ancient Indian monks, enlightened with the incessant worship of wisdom, is considered an invaluable asset in the field of world ethical knowledge through the ages. Through this paper a modest effort is being made to have an insight towards the ethical lessons prescribed in Jaina Philosophy.

Bibliotecas digitales en tiempos de pandemia
Authors: Térmens Graells Miquel
Published: June 2021

El debate analiza a través de una serie de preguntas planteadas a cinco profesionales responsables de bibliotecas digitales españolas, los cambios experimentados en su servicio a causa de la pandemia de la Covid-19. En las respuestas se constata que mientras que las bibliotecas universitarias estaban bastante preparadas para dar un servicio totalmente en línea, las bibliotecas de otro tipo tuvieron problemas con su infraestructura tecnológica y circuitos de trabajo. Existe un consenso en destacar la importancia de mantener los servicios de soporte al usuario y en aprovechar más las redes sociales como vía de difusión. El aumento de las colecciones y servicios digitales es inevitable, pero se han de encontrar vías para evitar la brecha digital y también para dar sentido a los servicios presenciales.

La pandemia ha puesto de manifiesto fortalezas y aún debilidades en el ámbito digital, pero también que algunos servicios digitales ya tienen veinte años de presencia. En este tiempo ha cambiado de forma radical la oferta de información y cómo ésta es utilizada por los usuarios, por lo que ya es urgente emprender un debate sobre cómo deberán ser las bibliotecas del futuro y que tipo de servicios ofrecerán.

Purpose The aims of this study were to identify Continuous Improvement (CI) practices prevailing in the manufacturing companies with regards to Visual Management, Employee Engagement, Leadership and Risk Management; to identify continuous improvement tools that have been adopted by the manufacturing companies; and to analyze the critical success factors for implementing CI practices in manufacturing companies. Design/methodology/approach For this study, a survey questionnaire was used to collect the CI practices information from manufacturing companies in Oman. 146 samples were collected from 75 manufacturing units selected at random from the Public Establishment for Industrial Estate database. The data was analysed for reliability, robustness, ranking tests using Statistical Package for Social Statistics (SPSS). Findings The majority of the manufacturing firms were using only the CI program for the past five years. However, there was not substantial cost savings for these businesses. The overall sales increased, while the average processing time had declined and the product recalls also had increased. The most important factors identified for the effective implementation of CI in industrial firms were effective communication, top management encouragement, and employee involvement and conducive organization atmosphere. Social Implications Sultanate of Oman like any other GCC countries is undergoing a critical phase in economy because of the oil price plunge combined with ongoing COVID-19 pandemic. The paper will be of use to academics, researchers and continuous improvement practitioners. Originality/value So far, very few studies have been conducted in analyzing the factors correlated to CI in the Omani context and no study was carried out before in exploring the CI application in the Sultanate of Oman.

Published: June 2021

Abstract Purpose of study The objectives of the study were to analyze the effects of transformation from GDS to NDC from the perspectives of the travel agencies in Oman; to find out the concerns of the travel agencies in Oman with regards to the implementation of NDC and to compare the benefits of NDC content with GDS from the perspectives of the travel agencies in Oman. Design/Methodology/Approach A questionnaire survey, telephone, and personal interview were conducted with 19 top leading travel agencies in Muscat region, Oman. Each Travel agent manager was given the questionnaire through google forms for the questionnaire. The telephone/ personal interview was also conducted. Around 78 employees were targeted out of which only 13 responded. The data collected was analyzed using Statistical package. Findings The findings support the fact that Oman being a small market with many small and medium players’ implementations of NDC is slow. The current pandemic has slowed it down even further. But their help being offered in terms of training and awareness by the NDC platform and some major airlines to speed up the adaptation. The study showed that the high cost of technological implementation is going to be one of the major barriers to complete switch to NDC system. As of now, the travel agents will be settling for GDS with NDC. Research Implications The adaptation by NDS has been slow especially by airlines. With IATA pushing the implementation, major airlines are slowly but surely adapting it as they can see the benefits they can derive. The customers too are benefiting from direct buying. The travel agencies in Oman especially small and medium-sized travel agencies are the ones who are most affected and there is not enough research being done to find what is it that is stopping them from adapting. Social Implications The pandemic has devastated the travel industry overall. Many small and medium businesses have been forced to shut due to lockdowns. Further, more people becoming comfortable with online shopping and willing to spend less, it will be a while before travel agents can start earning the same level of revenue they were enjoying before the pandemic. This will have an impact on unemployment as well as the inability to meet loan commitments. This can have a ripple effect. Originality/Novelty Few academic research has been carried out on NDC, especially in the Middle East. This research is the first of its kind which is dedicated to travel agents from Oman. The fact that NDC is set to revolutionize the shopping experience for the consumer one cannot ignore the fact that it is set to blow a dent in the revenues of the Travel agents.

Para responder a dicha pregunta, se ha realizado un análisis documental sobre los datos disponibles de las Mypes nacionales, específicamente en el contexto actual.
Seasonal assessment of suface and ground water in Himalayan footh hill, Uttarakhand
Authors: KUMAR RAJDEO
Published: June 2021

An investigation was carried out to assess the quality of water in Himalayan foot hill, Uttarakhand. The surface and ground water samples were collected during summer, monsoon and winter season from four sites. These water samples were analysed for their physico-chemical properties and heavy metals. The results revealed that the pH, EC, TDS and bicarbonate ranged from 7.2 to 7.7, 350.7 to 563.2 µScm-1, 385.7 to 906.7 ppm and 146.7 to 186.3 ppm, respectively in surface water, irrespective for season. The corresponding values for these parameters in ground water ranged from 7.1 to 7.3, 335.5 to 364.0 µScm-1, 316.7 to 610.0 ppm and 144.5 to 164.2 ppm. The concentrations of Na, K, Ca and Mg varied from 4.4 to 12.6 ppm, 1.8 to 18.0 ppm, 25.5 to 42.9 ppm and 16.6 to 32.0 ppm, respectively in surface water whereas the concentrations of these elements in ground water ranged from 4.6 to 6.8 ppm, 1.5 to 7.7 ppm, 19.5 to 35.6 ppm and 16.0 to 28.8 ppm, respectively. All the heavy metals were in safe limit in both sources of waters. In general, the concentrations of these water quality parameters were relatively higher during summer and lower in monsoon.

In vitro effect of chromium, lead and manganese on seed germination, growth and mineral composition of finger millet (Eleusine coracana)
Authors: VARAPRASAD DUDDELA
Published: June 2021

It is a well-known fact that heavy metal stress is one of the serious threats to agricultural yield. In the present work, heavy metal screening was carried out using chromium (Cr), lead (Pb) and manganese (Mn) independently on finger millet [Eleusine coracana (L.) Gaertn.] seed and seedling growth under in vitro conditions. Adverse effects of chromium on finger millet seed germination as well as seedling architectural damage were noticed from 10 ppm onwards. Particularly, 30 and 15 % of seed germination was noticed at 50 and 100 ppm concentrations of chromium, respectively. But the extremely toxic lead did not prove its toxic nature when compared to chromium and even at 100 ppm concentration the reduction of seed germination and seedling growth were minor. Manganese promoted the seed germination even at 50 and 100 ppm concentrations. In ICP-OES (inductively coupled plasma-optical emission spectrometer) analysis, contents of residual nitrogen, phosphorous, potassium and sulphur were reduced in seedlings grown on media containing high concentrations of chromium which indicated the toxic levels of this particular metal in this crop. In addition, the sulphur content slightly increased in seedlings treated with higher concentration of lead and showed almost double amount in seedlings treated with high concentration of manganese. The contents of microelements varied with different treatments and as expected content of managense increased in seedlings treated with high concentration of manganese.

ASPECTS OF LEXICAL AND STYLISTIC CHANGES IN CRISIS
Authors: AHMED Khalid Ahmed Hassan
Published: June 2021

This study aims at exploring linguistic changes in periods of crisis. We feel that great linguistic changes will appear due to the wide spread of the fatal diseases that affect human beings existence on this earth. To fight the disease people should raise their awareness of the disease through language as a linguistic media that helps them to some extent building defenses against the disease. This linguistic shift will be followed with some modifications on the existing form of language either by coining new lexicons or reformulating new terms with new concepts and values. On the stylistic matters some changes are also expected to let people express themselves either socially or economically. The interest of this study will be directed to changes in lexical usage or changes of stylistic issues of the crisis under investigation, namely in this present study the pandemic of Corona Virus that is commonly known as Covid 19. The study will be a qualitative survey of the changes that this disease has led to. The related theoretical framework and literature will be outlined as guidelines for this study. Its importance, methodology and the procedures will also be stated to show the techniques of data collection in order to obtain the main results and the discussion, then finally a summary of the main findings, recommendations and suggestions for further future studies will bring the paper to its logical end.
DESCRIPTIVE STUDY OF DYSLEXIA AND DYSGRAPHIA SUFFERED BY IRAQI EFL STUDENTS
Authors: DALAF Muna , TALIB Angham
Published: June 2021

One of the important topics of research is the topic of “specific learning disorders”. Not having the sufficient knowledge about such topic will make the instructors confused when it comes to deal with students who have such disorders. In addition, a great amount of the instructors’ efforts and time will be lost. The following study tries to explore the background knowledge of Iraqi EFL college instructors of these disorders. In order to gather the data, two methods were used; the first method is a questionnaire which was given to twenty instructors to be answered. The second method is a number of interviews with a group of other instructors. The results of this study showed that those instructors who participated have contradictory background knowledge about such topic. As a result, it is important to do more workshops that increase the background knowledge of the instructors and make them more capable of dealing with such disorders. ers.

Within the Developing countries accident is that the main reason for death. If we watch top 10 countries within the globe all of them are mountain road and curve roads. Within the mountain there’ll be tight curves and narrow roads due to this visibility is blocked .In these reasonably situation the motive force of vehicle cannot see vehicle coming from opposite side. The developing countries need to adopt the model followed by developing countries like Netherland & Denmark where roads are built in line with their function .in developing countries buses and trucks are more involved in accidents because of lack of proper safety standards. Thousands of individuals lost their lives due to this problem. . utilization of day time light, high mounted stop lamps, reflectors, colorful clothing has decreased the incidence of crashes due to poor visibility. The answer of this problem is alerting the motive force about the vehicle coming from opposite side. This is often done by keeping the ultrasonic sensor in one side of the road before the curve and keeping a LED light after the curve ,so that vehicle comes from one side of curve a senses and LED light glow at opposite side. By viewing the LED light on /off criteria the motive force can become alert and may hamper the speed of vehicle.

Agricultural Mechanics Preparation: How Much Do School Based Agricultural Education Teachers Recieve?
Authors: Clark Taylorann K. , Anderson Ryan , Paulsen Thomas H.
Published: June 2021

The purpose of this quantitative study was to determine the amount of preparation Iowa inservice secondary agricultural education teachers received in agricultural mechanics at the university level. Secondary School Based Agricultural Education instructors attending the Iowa Association of Agricultural Educators’ summer conference were given a paper-based survey instrument to report their perceptions of the agricultural mechanics skills and training they had received at the postsecondary level. Agricultural education teachers indicated that safety, welding, and construction were among the skills with highest concentration of instruction received at the postsecondary level. The areas in which teachers received the least amount of preparation were surveying, technology, and tractor skills. The overall lack of instruction in agricultural mechanics at the postsecondary level may lead to inexperienced and underprepared teachers. We recommended weekend or summer training be offered for inservice teachers who did not receive or received very little training at the postsecondary level. It is also recommended postsecondary institutions organize consistent ways in which agricultural mechanics courses are offered so that preservice agriculture teachers receive appropriate training prior to entering the profession.
The Effect of Authenticity on Project-Based Learning: A Quasi-Experimental Study of STEM Integration in Agriculture
Authors: MckKibben Jason D. , Murphy Timothy H.
Published: June 2021

Researchers have reported that participation in agricultural education reinforces STEM concepts, often through project-based learning. The use of projects is common in agricultural education. However, the instructional importance of certain elements of these projects is not well understood. We conducted a quasi-experimental study to examine the effect of project authenticity on learning. Agriculture students in Texas were sampled and assigned as a cohort to one of four treatment groups (N = 219). Fourteen cohort groups (class periods) were identified across five sites. Each cohort was randomly assigned to one of four project types to learn about electricity. The four project types varied in their degree of project authenticity. Analysis of covariance (ANCOVA) was used to test the effects of project authenticity on change scores in a pretest-posttest quasi-experimental design. Learning varied on authenticity. A test of project type groups yielded statistically significant results (p < .025) with small effect size (ω2 = .04). Pairwise comparisons revealed no differences between the most and least authentic projects but did reveal statistically significant differences between the two projects with medium levels of authenticity, and the other two (i.e., least authentic and most authentic). The relationship between learning and authenticity was not linear. We recommend that teachers and curriculum designers deliberately consider the importance of authenticity when designing project based learning opportunities for students.
The Role of NFA Camps in Agricultural Education for Rural African American Boys in North Carolina

Published: June 2021

The New Farmers of America (NFA) was a national organization existing from 1934 to 1965 when it merged with the National Future Farmers of America (FFA) Organization. S. B. Simmons, a leader in agricultural education throughout African American public schools, and early founder of the NFA, worked diligently to provide a place for rural African American boys to develop leadership, citizenship, sportsmanship, and moral values. This place existed in the form of a North Carolina NFA camp. Established in 1953, the North Carolina NFA Camp, located in Onslow County, saw boys from across the state for a week-long experience. The benefits of the camp branched further than simply learning to start a campfire or host a cookout. Later dedicated the S. B. Simmons Camp, rural African American boys benefited from leadership classes, recreational activities, and even public speaking opportunities to further develop themselves. Although no longer in existence, the morals imprinted in students at the S. B. Simmons Camp are ever apparent today at the remaining North Carolina FFA camp and throughout the National FFA Organization.
