Business Simulation Games
Authors: Goi Chai-Lee
Published: May 2021

The history of the development of business simulation games started in 3000 BC, and the development of modern business simulation games began in the 1950s. Since the introduction of modern business simulation games, it has grown rapidly and is widely used by corporations, managers, educators, development consulting firms, and collegiate business programs for training and teaching purposes. A dynamic business environment and changing economic conditions require the reorientation and modification of educational programs. The learning process should focus on strengthening knowledge, skills, behaviours, and attitudes according to market needs and wants. The use of business simulation games in education can overcome this problem and even increase student motivation and engagement. This chapter covers three main sections: (1) history of business simulation games, (2) types of business simulation games, and (3) the use of business simulation games in teaching and learning.

Published: May 2021

Education has always been a challenge, today even more so given the difficulties of the moment, to support school in the time of COVID-19. Schools at every level have reorganized the training offer, implementing technological solutions. All this has raised a problem: the division is no longer between those who have access to the network and those who do not, but between those who know and those who do not know these new tools. Lately the concept of digital divide, understood as a gap of opportunity between those who have and those who do not have digital skills, has evolved into the concept of digital inequality. Given these premises, the work investigates after careful analysis, the impact of digital systems on the educational system, such as the emergence of the “digital divide,” impacts on training within universities. To verify the “digital divide,” the work proposes a quantitative survey carried out through a questionnaire submitted to a sample of students. The subject of the survey is given by the students of the University of Calabria.

Authors: Kang Yowei , Yang Kenneth C. C.
Published: May 2021

The advent of mobile communication devices has become an essential part of contemporary human experiences. However, what are consumers' experiences with their mobile devices on a daily basis? This exploratory chapter used an experience sampling method to extract quantitative and qualitative experiential data to understand how concerns over location-sensitive privacy issues affect how consumers feel about mobile phone in their daily lives. Participants from both Taiwan and U.S. took part in this study and recorded their daily experiences with the presence of smartphones at different parts of one single day. The findings suggest that cross-national consumers generally agree with the functional benefits of mobile devices, but at the same time, express their disruptive effects on their daily lives. Taiwanese consumer mood states are overall consistent with those of American participants who similarly feel more disrupted with their mobile phones. Discussions and implications are provided.

Published: May 2021

Object detection and tracking have been extensively used in many applications including security and surveillance. This chapter addresses the problem of human detection and tracking in surveillance videos with noise. The system proposed deals with video processing utilizing Kalman filtering to enhance the process in the presence of challenging weather conditions. To support the target idea, some experiments are introduced to measure the deviation between both the noiseless and the noisy videos and to study the effect of each filter within each noise type of video disturbance. The most efficient masking system is used to enhance the outcome in the presence of video degradations. The proposed tracking and detection technique achieves achieve an average correct assigned tracks accuracy of about 95% for noiseless video. This is due to the challenging video degradation depending on the type and level of noise. In case of noisy videos by applying the correct filter mask, the accuracy of tracking in the presence of a median filter comes to around 90%.

Published: May 2021

Currently in Nigeria, different crimes ranging from ethnic clashes, domestic violence, burglary, financial fraud, kidnapping, pipe-line vandalism, and random killings by terrorist organizations, to mention a few, continue to plague the country. The conventional system of intelligence and crime record have failed to live up to the expectations as a result of limited security personnel, deficiency in effective information technology strategies, and infrastructures for gathering, storing, and analyzing data for accurate prediction, decision support, and prevention of crimes. There is presently no information system in Nigeria that provides a central database that is capable of storing the spatial distribution of various acts of terrorism based on the location where the crime is committed. This chapter presents the design of an information system that can be used by security agents for the storage and retrieval of criminal acts of terrorism in order to provide improved decision support regarding solving and preventing criminal acts of terrorism in Nigeria using modern technologies.

Authors: Kumar Jaydip , Saxena Vipin
Published: May 2021

Cloud computing is used for large shared resources to facilitate execution and storage. So there is a need of resolving crucial security issues to avoid data theft. Hence cloud security provides data encryption for security parameters to change plain-text to cipher-text. The homomorphic encryption technique is used for performing operations on encrypted data. To manage the huge and growing informational collections that are being prepared these days, great encryption execution is a significant advance for the common sense of homomorphic encryption techniques, the Paillier cryptosystem is also used by researchers for securing the decimal digits of information. In the present work, a hybrid Paillier cryptosystem technique is used for reducing the bit length of the cipher-text by performing hex code operations on encryption. The proposed method has been implemented in the use of two object-oriented programming languages i.e. C++ and Python programming languages. The simulated results show the minimum encrypted bit length as well as provide more secure data. And we have also analyzed our algorithm based on the two parameters namely space complexity and time complexity which are represented in the form of tables and graphs given below.

Published: May 2021

As the application of network encryption technology expands, malicious attacks will also be protected by encryption mechanism, increasing the difficulty of detection. This paper focuses on the analysis of encrypted traffic in the network by hosting long-day encrypted traffic, coupled with a weighted algorithm commonly used in information retrieval and SSL/TLS fingerprint to detect malicious encrypted links. The experimental results show that the system proposed in this paper can identify potential malicious SSL/TLS fingerprints and malicious IP which cannot be recognized by other external threat information providers. The network packet decryption is not required to help clarify the full picture of the security incident and provide the basis of digital identification. Finally, the new threat intelligence obtained from the correlation analysis of this paper can be applied to regional joint defense or intelligence exchange between organizations. In addition, the framework adopts Google cloud platform and microservice technology to form an integrated serverless computing architecture.

Authors: Lee Sang Joon , Kwon Kyungbin
Published: May 2021

Although group work has shown positive effects on student learning, it has been challenging to encourage students to actively engage in group work and assess individual contributions to group projects, particularly in online courses. Peer assessment is a peer evaluation method in which each student assesses group members on how well they did on a group project thereby facilitating students' participation in the group project. The purpose of this study was to examine how students perceived peer assessment as a facilitating and assessment strategy and whether their perceptions were different between online and face-to-face classes. The findings showed both face-to-face and online students perceived that peer assessment was not only a good way to facilitate students' participations and contributions, but it was also a reliable way to assess students' contributions to a group project.

Published: May 2021

Medication non-compliance is common among patients suffering from chronic disease. The research aims to find the effectiveness of food timing as a form of intervention to improve medication compliance. 509 patients were interviewed who were under the medication and had their treatment from Central Referral Hospital, Sikkim. The technique of probability estimates, risk difference, relative risk, and odds ratios were used to do the analysis and predictions of medication compliance when food timing was used as a form of reminder. Analysis of confidence interval at 95% ensured that the results obtained were due to the use of reminder and not by chance. The study reveals that with the help of food timing as a form of reminder, a patient has 50.2% lower odds of deferring from the scheduled time of medicine. There are 129.2% greater odds of completing the course of medication, 41.4% lower odds of missing the medication consciously, and there are 56.6% lower odds of missing the medication dose. The probability numbers indicate the effectiveness of usage of this form of reminder.

Published: May 2021

Hospital statistics on morbidity and mortality are essential in assessing disease burden, evaluation of health policies and health planning. The study aimed to determine the morbidity pattern and short-term outcome among medical admissions in the Niger Delta University Teaching Hospital (NDUTH), Bayelsa State, Nigeria. This retrospective 7-years disease audit was carried out in the medical wards of NDUTH, Bayelsa State, Nigeria. Information extracted included name and gender of patients, diagnoses and disease outcomes. One thousand, one hundred and twenty five (60.5%) females and seven hundred and thirty three (39.5%) males had complete records and were therefore used for the analysis. The mean age of the patients was 50.14±16.66 years with males being older (p<0.001). Non-Communicable Diseases (NCDs) accounted for a majority of cases (1270; 68.4%) while 588 (31.6%) were Communicable Diseases (CDs) NCDs were more prevalent among males and older individuals (p<0.03; p<0.001) and showed a rising trend over the years. CDs were however the leading cause of morbidities among females. The commonest diagnoses among males were retroviral disease, stroke, heart failure, pulmonary tuberculosis, diabetes and renal disease with women showing a similar trend except that heart failure replaced stroke as the second commonest morbidity while stroke came third, followed by diabetes, renal disease and hypertension. The all-cause mortality rates were 10.6% and 15.9% for females and males respectively. The major causes of mortality were infectious diseases and circulatory disorders for both genders. About 6.4% males and 3.8% females Left Against Medical Advice (LAMA). The pattern shows a rising prevalence of NCDs. Although CDs witnessed some decline, it however remained prevalent. The mortality rate was high while a good proportion LAMA. There is a need for strategic health programs to address this increasing tide of NCDs in our society, control CDs, and improve patient care while reducing mortality.

Published: May 2021

Granulomatous amebic encephalitis (GAE) caused by Acanthamoeba is a rare infection with central nervous system (CNS) involvement usually with fatal consequences. Currently, information regarding GAE in children is scarce and is limited only to case reports and case series. A 13-year-old immunocompetent male patient with a 6-month history of progressive and intermittent headaches presented to our institution. One week before hospital admission, the patient showed signs of CNS involvement. Magnetic resonance imaging revealed multiple lesions with supra- and infratentorial cerebral abscesses. An empiric treatment with combined antibiotics was given, but the patient died after 20 days of hospital stay. A postmortem diagnosis confirmed GAE. Although it is a rare disease in pediatric patients, GAE should be considered in children with a chronic history of fever, headache, and vomiting with CNS involvement.

Published: May 2021

Metal organic frameworks are formed by the three-dimensional linkage of metal cores and organic linkers. In this work, bismuth-based metal organic framework (Bi-MOF) has been synthesized by using 5-hydroxyisophthalic acid (H2HIA) as linker via hydrothermal method. The said MOF was structurally characterized by UV/Vis, Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), 1H NMR, energy dispersive spectroscopy (EDS), thermogravimetric analysis (TGA) and X-ray diffraction technique. This MOF showed highly porous structure with surface area 1096 m2/g as determined by BET analysis. A model batch adsorption experiment was performed to evaluate the efficiency of methylene blue (MB) dye removal from aqueous media. It was found that monolayer adsorption capacity calculated from the Langmuir isotherm was 0.6240 mg/g. Bi-MOF was also screened for its antibacterial and luminescent behavior.

Biomolecules present in the plant extracts have potential to reduce metal ions to nanoclusters by a single-step green synthesis approach. In the current study, we have synthesized the silver nanoclusters (AgNCs) from a medicinal plant, Melia azedarach and studied their catalytic activity toward the reduction of 4-nitophenol to 4-aminophenol and organic dyes. Morover, the phytochemical analysis of the plant extract was carried out in order to determine the bioactive compounds present in it. Metallic nature of the synthesized AgNCs was verified by X-ray diffraction study, while their morphology and size of was confirmed by transmission electron microscopy and Zetasizer, respectively. The study revealed that they were 56±2 nm in size and formed clusters. Fourier transformed infrared spectroscopy gives information about the different functional groups present in synthesized these NCs. Furthermore, the important catalytic applications, such as catalytic reduction of 4-nitrophenol in the presence of mild reducing agent NaBH4 and the catalytic degradation of organic dyes was monitored by FTIR. Therefore, these results indicate that the obtained nanomaterials have important applications in industrial areas.

Authors: Unagwu Benedict. O. , Ayogu Roseline. U. , Osadebe Vivian.O.
Published: May 2021

The study investigated the effects of animal manures (cow manure, CoM; chicken droppings, CkD; and pig manure, PiM) applied at 15 t ha-1 equivalent rate on the soil and growth performance of okra grown in a degraded ultisol. The treatments (CoM; CoM; PiM and Control unamended) were laid out in a completely randomized design and replicated three times. Animal manure application had significant effects on soil properties. Soilorganic matter increased by over 9% in the amended treatment relative to the control treatment. Except for N, increases in P (circa 14-70%)and K (circa 15-46%) nutrients were higher for CkD treatment than in other  treatments. Generally, the amended treatments maintained a significantly higher (p ≤0.05) plant leave number, stem girth, plant height, okra pod length and yields when compared with the Control treatment. The results indicated that application of animal manure enhanced okra growth performance. The findings suggest that animal manure application can potentially increase okra yield when grown in a degraded soil. It is recommended that farmers use ample (15 t ha-1) ) quantity of animal manures to increase their crop yields, which invariably will enhance their income.

Authors: YILMAZ Savaş
Published: May 2021

Tarihi süreç içerisinde kadim medeniyetler, devlet düzeninden adaletin sağlanmasına kadar dinin toplum ve yönetim üzerindeki büyüleyici iksirinden faydalanmaya çalışmışlardı. Osmanoğulları da toplumda huzurunun sağlanmasında bu büyüleyici gücün etkisinde kalmışlar, örfî güç ve otoritelerini şerî kanunlarla bezeyerek meşruiyetlerini toplumun genelinde hâkim kılmayı amaçlamışlardı. Ayrıca güç ve iktidarlarını dinî değerlere saygı ve sevgi ile donatarak Hz. Muhammed’in, ehl-i beytine olan hürmetlerini de göstermişlerdi. Onların bu davranışları ehl-i beyte olan sevgi ve saygıyı daha da artırmıştı. Bu durumdan faydalanmaya çalışan müteseyyidler (sahte seyyid ve şerifler); devletin bazı muafiyetlerinden faydalanarak bu durumu gelir kapısı olarak görmüşlerdi. Merkezî yönetim, seyyid ve şeriflik iddiasında bulunanlar hakkında şikâyetler nedeniyle araştırmalar yapılması için başkentte Nakîbü’l-eşrâflık müessesini kurmuştu. Böylece devletin muhtelif yerlerinde kendilerini seyyid ve şerif olarak tanıtarak halkın dinî değerlerini istismar edenlerin halleri taşra yöneticileri vasıtasıyla bu makama bir tezkere ile sorulmuş ve cevabî yazılara göre kararlar verilmişti. Bu bağlamda dinî değerlerin ve toplumsal huzurun sağlanmasında önemli güç olan Nakîbü’l-eşrâflık makamı, din istismarcılarının davranışlarının engellenmesinde önemli görevleri yerine getirmiş ve saltanatın kaldırılmasıyla da kurumsal yapıya son verilmişti. Çalışmanın amacı; Osmanlı idaresinin, Nakîbü’l-eşrâflık müessesesiyle müteseyyidleri tespit ederek dinî değerlerin istismar edilmemesi için almış olduğu tedbirleri belirtmektir. Divân-ı hümâyûna, müteseyyidler hakkında şikâyetlerin yapılması nedeniyle mühimme defterleri araştırmada asıl kaynak olarak belirlenmiştir.

Published: May 2021

Introdução: A expectativa de vida da população brasileira tem crescido consideravelmente, assim é importante compreender o modo como a pessoa idosa tem percebido suas condições de saúde, para uma melhor qualidade de vida (QV). Objetivo: verificar a associação da autopercepção de saúde com a QV de idosas que praticam atividade física (AF) e analisar a correlação entre o tempo despendido em AF e a percepção de saúde. Método: Quantitativo, transversal e correlacional. Instrumentos: International Physical Activity Questionnaire (IPAQ), World Health Organization Quality of Life – BREF e OLD, Sociodemográfico com a pergunta “De um modo geral, você se considera uma pessoa saudável?” e o cálculo do Índice de Massa Corporal (IMC). Foi realizado a análise descritiva das variáveis, teste de coeficiente de correlação ponto-bisserial e realização da regressão linear múltipla com significância de p<0,05. Resultados: houve uma boa percepção da QV e a percepção de saúde foi positiva na maioria da amostra. O IMC denunciou sobrepeso das participantes. Verificou-se a existência de correlação inversa no domínio Físico da QV geral, nas idosas com percepção negativa de saúde, sendo considerada uma correlação moderada (r=-0,436; p=0,00). Conclusão: Não houve significância estatística para associar a percepção de saúde com a QV, apesar da percepção de saúde delas ser positiva e o tempo de prática de AF semanal estar acima do recomendado pela OMS. Houve uma boa percepção da QV geral pelo grupo, porém, a correlação entre a prática de AF e do domínio Físico das idosas com percepção negativa de saúde foi inversa.

Afetados diretamente neste processo estão os estádios ou arenas que também pararam. Contudo, em meio a pandemia percebe-se que algumas destas instalações foram requisitadas para fazer parte do combate à COVID-19. Assim, o presente ensaio tem como objetivo examinar como foram utilizados os estádios voltados a prática do futebol no período de lockdown esportivo. O estudo é delimitado pelo período temporal entre o mês março e a primeira quinzena julho de 2020. Os resultados mostram estádios públicos e privados recrutados para combater a COVID-19 no mundo utilizados como: hospitais de campanha, abrigos ou centros de isolamento de pessoas, depósitos de doações médicas e pontos de atendimento de diagnóstico para ampliar a assistência de saúde pública. As considerações finais apontam para a versatilidade dos estádios que se converteram para servir a saúde e a população, reforçando o entendimento de que os torcedores retornarão seguramente somente com o desenvolvimento de uma vacina ou tratamento contra o vírus.

This work was carried out to evaluate the hydrogeological and geophysical properties of Abakaliki and Afikpo environs. Forty-seven (47) Vertical Electrical Sounding data were acquired with electrode spacing (AB/2) of 500m using Schlumberger electrode configuration. Conventional curve matching techniques were used to interpret the data and obtain initial model parameters. Results of the study showed 3-7 electric layers which indicate multiple aquifer system. QQH, QHK, KHK and QQHK models were the Vertical Sounding curves obtained. The aquiferous layers make up the third and fourth layers. The resistivity of the aquifer varies from 10.74Ωm to 13201Ωm with an average of 1013.58 Ωm. Aquifer depth ranges from 6.2m to 92.5m with an average aquifer depth of 27.07m, while the aquifer thickness varies from 2.3m to 55.87m with an average of 15.61m. Transverse resistance varies from 65.34Ωm2to 7079.14 Ωm2 with an average of 9966.29 Ωm2; and the longitudinal conductance varies from 0.00018Ω-1 to 1.65 Ω-1 with an average of 0.026 Ω-1. From the study, 49% of the study area falls under the poor protective rating while 21% falls under the weak rating with 25% and 5% which makes up the moderate and good ratings respectively. Using the average longitudinal conductance, it is observed that the study area is moderately protected.

Context: Systemic Lupus Erythematosus (SLE) is a complex chronic autoimmune condition that represents a source of disability. In pregnant women, it can create a burden of the low quality of life and cause deleterious effects on maternal, fetal, and neonatal outcomes.

Aim: The study aimed at evaluating the effect of self-care guidelines on the quality of life among pregnant women with SLE.   

Methods: A quasi-experimental study design (time series, one group only, and pre-post intervention assessments) used. Purposive sampling used to recruit fifty pregnant women diagnosed with SLE. The study conducted at three sites: Rheumatology Outpatient Clinic at Ain Shams University Hospital, Rheumatology Antenatal Outpatient Clinic, and Labor Unit at Ain Shams Maternity Hospital. Seven tools of data collection utilized in this study and Arabic self-care guidelines distributed as supporting educational material for the pregnant women with SLE.

Results: Findings of the present study showed that there was a highly significant improvement on SLE activity index, follow- up lab investigations, quality of life, and health assessment through evaluation of daily living activities after using self-care guidelines.

Conclusion: The results of the current study supported the research hypothesis that the pregnant women with SLE who exposed to self-care guidelines will have a better quality of life compared to their pre-intervention level, which reflected upon improving pregnancy outcomes. Based on the study results, the following recommendations are forwarded; application of the study intervention with the distribution of the clear Arabic self-care guidelines on a large scale in other sittings caring for pregnant women with SLE.

Keywords: Self-Care, Guideline, Quality of Life, Pregnant Women, Systemic Lupus Erythematosus.
