Authors: Osei Charles Dwumfour , Zhuang Jincai , Menyah Michael Verner , Gyasi Priscilla Adomako
Published: January 2021

In recent times, there has been an increasing push to develop social entrepreneurship as a strategy for poverty alleviation, rural development and economic growth in most developing countries. This has accounted for several policies to encourage more individuals and organizations to venture into social entrepreneurship yet less is known about the intriguing factors that account for the intentions of especially overseas students from developing countries to venture into social entrepreneurship. Hence, this study applied the Structural Equation Model with Smart PLS software to examine some key determinants of social entrepreneurship intentions from the perspectives of overseas students from developing countries currently studying in China. A total sample of 280 overseas students from the developing countries currently studying at the Jiangsu University in China was randomly selected for the study. The results revealed that Psychological capital, Empathy, moral judgment, knowledge, and social support have significant impacts on social entrepreneurship intentions. Importantly, Psychological capital partially mediates the impact of empathy, moral judgment, knowledge and social support on social entrepreneurship intentions. The study recommends that overseas students in China should be exposed to social entrepreneurial skills and social problems as part of their training to be able to develop their intentions and strong behaviors for social value creation and social entrepreneurship. The results have both theoretical and empirical contributions to extending research scholarship in the field.

Authors: Alogla Ageel
Published: January 2021

Weight and volume are a direct impact on diving which is an important indicator of the overall performance of the deep-sea submersible structure. In order to increase the payload, improve endurance, reduce energy consumption, improve work efficiency, and therefore must accordingly reduce the total weight of the submersible. The design of underwater vehicles with minimum buoyancy factor is a major requirement from the underwater vehicles design point of view. The composite material pressure hull is a new concept due to the excellent structural performance. Therefore, in the present study, a comparison between three different pressure hulls with the same volume and various materials subjected to the same hydrostatic pressure will be investigated. The first, model was constructed from carbon fibre, while the second one constructed from steel (HY100) and the last one constructed from Titanium alloy. The finite element analysis (FEA) was executed using ANSYS. The results illustrated that the best buoyancy factor and the minimum mass occurred in the case of the pressure hull constructed from carbon fibre.
Hasidik Yahudilikte Vaat Edilmiş Topraklar Fikri: İsrail Karşıtlığı
Authors: SEYFELİ Canan , AKDEMİR Hüseyin
Published: December 2020

Çalışmanın konusu Hasidik Yahudiliğin vaat edilmiş topraklar fikri ve bu fikrin oluşturduğu İsrail karşıtlığıdır. Vaat edilmiş topraklar fikri seçilmişlik, ahitleşme ve tek Kutsal Mabet ile bütündür. Bunları birleştiren ise Mesih beklentisidir. Yahudiler vaat edilmiş topraklarda Süleyman’ın mabedi Tanah’da belirtildiği şekilde inşa ettiğinde zirveyi yaşamışlardır. Ancak, Beytü’l Makdis’in ve Kudüs’ün iki defa tahribi Yahudileri bu topraklardan uzak yaşamaya mecbur bırakmıştır. Diaspora, Tanrı’nın seçtiği ve ahitleşerek vaat ettiği kutsal topraklarda tek mabet etrafında şekillenen bir hayattan mahrum kalma ve özlem demektir. Özlemin Mesih’in gelişiyle sona ereceğine inanç ise geleneksel kabuldür. Ancak Mesih gelmeyince Fransız İhtilali’nden sonra yükselen milliyetçilik akımı ve antisemitik olaylar Yahudileri Siyonizmi kurmaya itmiştir. Siyonizm sosyal, siyasal, ekonomik ve askeri alanlarda verdiği mücadelelerle 1948’de İsrail’i kurmuştur. Ancak insan eliyle kurulduğu için geleneksel Yahudilik tarafından meşru görülmemiştir. Hasidik Yahudilik ise Siyonizmi ve İsrail’i doğal olmamakla ve Mesih’in gelişini geciktirmekle suçlamış ve seküler yaşam biçimini reddetmiştir. İsrail karşıtlığını fiili şekilde sürdürmektedir.

Japanese film studies is an academic discipline and research community focusing on the multifaceted aspects of Japanese cinema. Deeply interdisciplinary, it employs theories, critical approaches and methods from different fields such as film studies and cultural studies to understand Japanese films as works of art, cultural products and social practices. What makes a film “Japanese”, and even what is a film, are far from easy questions, particularly in the globalised, transnational and digitalised world in which we now live, but nevertheless are issues that define the disciple and its historiography.

Histologic variants of acinar prostate carcinomas: Clinicopathologic importance
Authors: Singh Harmanjot , El-Zaatari Ziad M. , Ro Jae Y.
Published: January 2021

Acinar carcinoma comprises more than 90% of prostatic adenocarcinomas and is characterized by a small gland proliferation with an infiltrative growth pattern. The numerous, variably-defined histological variants of prostatic adenocarcinoma can prove to be diagnostic challenges and show prognostic differences when compared to the usual acinar carcinoma, thus emphasizing the importance in accurate recognition.
Variants of acinar prostatic adenocarcinoma include the atrophic, pseudohyperplastic, microcystic, foamy gland, mucinous (colloid), signet ring-like cell, pleomorphic giant cell, and sarcomatoid variants. The atrophic, pseudohyperplastic, microcystic, and foamy gland variants can be challenging to diagnose due to their deceptively benign appearance. While the atrophic, pseudohyperplastic, microcystic, and foamy gland variants usually present as low-grade malignancies (Gleason score 6-7), the mucinous (colloid), signet ring-like cell, pleomorphic giant cell, and sarcomatoid variants often present as high-grade malignancies (Gleason score >7) and are usually associated with a worse prognosis.
Small cell carcinoma is not considered as a variant of acinar carcinoma, is classified under neuroendocrine tumors, and is recommended not to be assigned a Gleason score. Small cell carcinoma is often preceded by a diagnosis of acinar adenocarcinoma, rarely presents as a de novo tumor, and, as in other organs systems has an aggressive clinical course.
In this review article, we discuss variants of prostatic acinar carcinomas and briefly discuss small cell carcinoma. Awareness of variants of acinar prostate carcinoma and their clinicopathologic features is essential to rendering an accurate diagnosis and clinical management of patients with these tumors.

Fuzzy-based Adaptive Framework for Module Advising Expert System
Authors: Alhabashneh Obada
Published: January 2021

In the enrolment process, selecting the right module and lecturer is very important for students. The wrong choice may put them in a situation where they may fail the module. This could lead to a more complicated situation, such as receiving an academic warning, being de-graded, as well as withdrawn from the program or the university. However, module advising is time-consuming and requires knowledge of the university legislation, program requirements, modules available, lecturers, modules, and the student's case. Therefore, the creation of effective and efficient systems and tools to support the process is highly needed. This paper discusses the development of a fuzzy-based framework for the expert recommender system for module advising. The proposed framework builds three main spaces which are: student-space (SS), module-space (MS), and lecturer-space (LS). These spaces are used to estimate the risk level associated with each student, module, and lecturer. The framework then associates each abnormal student case in the students’ grade history with the estimated risk level in the SS, MS, and LS involved in that particular case. The fuzzy-based association-rule learning is then used to extract the dominant rules that classify the consequent situation for each eligible module if it is to be taken by the student for a specific semester. The proposed framework was developed and tested using real-life university data which included student enrollment records and student grade records. A five-fold cross-validation process was used for testing and validating the classifying accuracy of the fuzzy rule base. The fuzzy rule base achieved a 92% accuracy level in classifying the risk level for enrolling on a specific module for a specific student case. However, the average classifying accuracy achieved was 89.2% which is acceptable for this problem domain as it involves human behavior modeling and decision making.
Detection of the Hardcoded Login Information from Socket and String Compare Symbols

Published: January 2021

Internet of Things (IoT) for smart homes enhances convenience; however, it also introduces the risk of the leakage of private data. TOP10 IoT of OWASP 2018 shows that the first vulnerability is ”Weak, easy to predict, or embedded passwords.” This problem poses a risk because a user can not fix, change, or detect a password if it is embedded in firmware because only the developer of the firmware can control an update. In this study, we propose a lightweight method to detect the hardcoded username and password in IoT devices using a static analysis called Socket Search and String Search to protect from first vulnerability from 2018 OWASP TOP 10 for the IoT device. The hardcoded login information can be obtained by comparing the user input with strcmp or strncmp. Previous studies analyzed the symbols of strcmp or strncmp to detect the hardcoded login information. However, those studies required a lot of time because of the usage of complicated algorithms such as symbolic execution. To develop a lightweight algorithm, we focus on a network function, such as the socket symbol in firmware, because the IoT device is compromised when it is invaded by someone via the Internet. We propose two methods to detect the hardcoded login information: string search and socket search. In string search, the algorithm finds a function that uses the strcmp or strncmp symbol. In socket search, the algorithm finds a function that is referenced by the socket symbol. In this experiment, we measured the ability of our proposed method by searching six firmware in the real world that has a backdoor. We ran three methods: string search, socket search, and whole search to compare the two methods. As a result, all methods found login information from five of six firmware and one unexpected password. Our method reduces the analysis time. The whole search generally takes 38 mins to complete, but our methods finish the search in 4-6 min.
A Customized Floating-point Processor Design for FPGA and ASIC based Thermal Compensation in High-precision Sensing
Authors: Sajjad Muhammad , Yusoff Mohd Zuki , Ahmed Muhammad
Published: January 2021

There are many types of sensors which require large dynamic range as well as high accuracy at the same time. Barometric altimeter is an example of such sensors. The signal processing techniques in the sensors are normally implemented using Field Programmable Gate Arrays (FPGAs) or Application-Specific Integrated Circuits (ASICs). The sensing variable in such type of the sensors is unwantedly environment dependent. So, for ensuring accuracy of the sensors this environmental dependency is minimized using the modeling and compensation techniques. In this work we have proposed a digital architecture for a programmable high precision computational unit which can be implemented in the FPGA or ASIC running the sensing algorithm of the sensors. This architecture can be used to implement polynomial compensation and it also supports reading and writing of the corresponding calibration coefficients even after the development of the sensors. Moreover, the architecture is platform independent. The architecture have been simulated for different FPGAs and ASIC and it has fulfilled the speed, accuracy and programmability requirements of the type of the sensors. The architecture has also been implemented and verified in a prototype of the barometric pressure sensor on Spartan-6 FPGA.

Published: December 2020

The purpose of the Joint Hydrographic Survey (JHS) implementation in Straits of Malacca and Singapore (SOMS) is to improve navigation safety in TSS by using Multibeam Echosounder  (MBES) technology. This is especially important given the increasing number of ships carrying out cross-transit through SOMS from year to year, while hydrographic information has not been updated since 1998. This study aims to analyze the effectiveness of JHS activities at SOMS conducted by Indonesia, Malaysia, and Singaporerelated to Indonesia's interests,  specifications, and procedures, as well as the use of force in JHS activities. This study uses qualitative methods with an exploratory approach and used the NVivo Plus 12 application to find themes from field interviews and used the Soft System Methodology (SSM). Based on the results of the study can be concluded that the effectiveness of JHS activities has been following what is expected by the three coastal countries, but the Indonesian Navy Hydrographic and Oceanography Center or Pusat Hidrografi dan Oseanografi TNI AL (Pushidrosal) as a learning organization is required to continue to be able to improve its capabilities in the implementation of JHS. From the gap of research results obtained several activities that can be carried out by Pushidrosal to increase the effectiveness of JHS in SOMS namely by evaluating the implementation of Security Officer (SO) and Technical Officer (TO) as well as preparing SOP that can be used as a standard in the implementation of JHS activities

Adult Hearing Loss: Applying the Five Models of Osteopathic Medicine to Diagnose and Treat
Authors: Adel Elnashar, OMS-III  , Zachary Lodato, OMS-III  , Sheldon Yao, DO, FAAO
Published: January 2021

Hearing loss is a common complaint with extensive cognitive, physical, emotional, social and financial implications. Many adults are expected to present with varying degrees of hearing loss by the age of 60 to 69 years old that can be classified according to the cause into conductive, sensorineural and mixed. There can be associated symptoms, like tinnitus, vertigo and otalgia and/or abnormal behaviors such as social withdrawal and difficulty with interpersonal communication. Somatic dysfunctions can accompany hearing troubles and range from fluid problems such as fluids accumulation in the middle ear, lymphatic congestion of the head and neck, and structural dysfunctions in the eustachian tube, neck musculature, thoracic spine, ribs and the cranial rhythmic impulse in addition to other neurologic dysfunctions such as sympathetic hyperactivity and viscerosomatic changes. In this review, we provide several suggestions that may assist the osteopathic family physician in identifying the various causes behind the hearing loss, especially life-threatening or quality-of-life limiting causes. We will also provide an effective treatment addressing the cause of the hearing loss presentation and associated somatic dysfunctions, alone or in conjunction with other appropriately trained health care providers, based on the understanding of the five models of osteopathic medicine and how they can apply toward the anatomical and physiological components of adult hearing loss.
Nighttime Blue Light Exposure and Breast Cancer
Authors: David Jaynes, MS, PhD  , Paul Switzer, MD
Published: January 2021

The purpose of this article is to provide background information and the current understanding of a less familiar cause of female breast cancer; exposure to ultraviolet light at night. Breast cancer is a common disease that causes significant morbidity and mortality in women. There are several risk factors for breast cancer, most of which are genetic and environmental in nature. An often-overlooked risk factor is exposure to blue light during night shift work, which decreases melatonin production. One of the many cancer-preventing properties of melatonin is to limit estrogen production. Increased lifetime exposure to estrogen is a well-known cause of breast cancer. Awareness of nighttime blue light exposure as a breast cancer risk factor by women doing night shift work and those exposed to nighttime light via smartphones and laptops, is essential information to know so that protective measures can be taken.
A new genus and species of rhinatrematid caecilian (Amphibia: Gymnophiona: Rhinatrematidae) from Ecuador
Authors: Wilkinson Mark
Published: January 2021

A new genus and species of rhinatrematid caecilian, Amazops amazops gen. et sp. nov., is described based on a single specimen from Orellana, Ecuador collected in 1990. Among other features the new taxon differs from all other rhinatrematid caecilians in having less than four annular grooves interrupted in the region of the vent and in the squamosal contributing to
the bony margin of the orbit. A consideration of its distinctive morphology suggests that it is plausible that the new taxon is the sister taxon of all other rhinatrematid caecilians. That the genus is known from a single specimen, and that this is the first new rhinatrematid species from the Andes described for more than 50 years, highlights the poor sampling (collecting) of rhinatrematid caecilians and limited knowledge of their diversity.
Make like a glass frog: In support of increased transparency in herpetology
Authors: Marshall Benjamin Michael
Published: January 2021

Across many scientific disciplines, direct replication efforts and meta-analyses have fuelled concerns on the replicability of findings. Ecology and evolution are similarly affected. Investigations into the causes of this lack of replicability have implicated a suite of research practices linked to incentives in the current publishing system. Other fields have taken great strides to counter incentives that can reward obfuscation –chiefly by championing transparency. But how prominent are protransparency (open science) policies in herpetology journals? We use the recently developed Transparency and Openness Promotion (TOP) Factor to assess the transparency promotion of 19 herpetology journals, and compare the TOP scores to broader science. We find promotion of transparent practices currently lacking in many herpetological journals; and encourage authors, students, editors, and publishers to redouble efforts to bring open science practices to herpetology by changing journal policy, peer-review, and personal practice. We promote an array of options –developed and tested in other fields– demonstrated to counter publication bias, boost research uptake, and enable more transparent science, to enrich herpetological research.
Comparison of eDNA and visual surveys for rare and cryptic bromeliad-dwelling frogs
Authors: Barata Izabela
Published: January 2021

Surveys of rare or cryptic species may miss individuals or populations that are actually present. Despite the increasing use of environmental DNA (eDNA) analysis to survey species in ponds, rivers, and lakes, very few studies have attempted to use eDNA for the detection of species using very small water bodies such as those accumulated within plants. Our aim was to investigate the feasibility of an eDNA sampling method for detecting Crossodactylodes itambe, an endemic bromeliad-dwelling frog from a remote location in Brazil. We collected water samples from 19 bromeliads for which we had observational data from direct visual surveys. We compared occupancy estimated from direct observations with the results
from quantitative real-time PCR based eDNA assays. For observational surveys, we used a single season occupancy model. We applied a novel Bayesian occupancy model to estimate occupancy from eDNA samples, as well as false positives and false negatives at different stages of the workflow. eDNA from bromeliad tanks provided reliable estimates, with very low error levels and improved detection when compared to detectability from direct observation. Estimated occupancies using eDNA and visual survey methods were similar. The method is feasible for species restricted to small water bodies and exposed to direct UV radiation, and particularly useful to survey remote locations and confirm species presence. eDNA analysis provides a viable alternative to destructive sampling of bromeliads or direct observation methods that require logistically challenging repeated observations. Therefore, eDNA methods may be widely applicable to sampling programmes of other amphibians that live in plants.

Introduction: In psychology, happiness is defined as a positive emotion which lasts longer than atemporary good feeling; it is a steady condition among one’s positive emotions and understanding oflife. Happiness is beneficial to the whole society, but the effects of happiness on university students,as the new blood and future makers of nations, have been of greater interest to researchers. Thepresent study aims to explore the factors that induce happiness in nursing and midwifery students.

Methods: The present study is a descriptive-comparative work of research conducted in 2017 on 200nursing and midwifery students at the Islamic Azad University of Jahrom in the south of Iran. Thesubjects were selected based on the census sampling method. To determine the degree of happinessin the subjects, the researchers used the Oxford Happiness Questionnaire developed by Argyle et al.in 1979. The questionnaire consists of 29 multiple-choice items scored on the Likert scale between0 and 3. The reliability and validity of the questionnaire have been tested and confirmed in severalstudies. The collected data were analyzed using SPSS v. 15.

Findings: Of the 200 students studied,81% (171) were female and 65.4% (138) were single. The mean happiness score of the subjects wasfound to be 40.1±9.1. On the happiness scale, the students’ happiness level was medium. 21.9% ofthe students had low happiness levels (a score of 0 to 28), 71.5% had acceptable happiness levels (ascore of 29 to 57), and 6.6% had high happiness levels (a score of 58 to 87). An analysis of the datashowed that there was not a significant relationship between the subjects’ levels of happiness and anyof their demographic characteristics except their term of study (p=0.05).

Conclusion: The findingsof the present study show that the degree of happiness among nursing and midwifery universitystudents is medium. Since nursing and midwifery university students are potential labor force in thehealthcare systems of societies, it is essential that they maintain acceptable levels of happiness whichis a criterion of psychological health. Accordingly, it is recommended that organized measures betaken to improve the psychological health of students and keep it at satisfactory levels throughoutthe duration of their education.

Published: December 2020

Joint pain is a common complaint in the paediatric age group with overuse and traumatic injury being the common causes. However, joint pain involving multiple sites, persistent or recurrent, and severe may suggest other diagnoses. One of the possible groups of diagnosis is rheumatology in nature, which is often difficult to diagnose, especially in paediatric patients. Gouty arthritis is a rather uncommon rheumatology problem in children and the diagnosis is often missed at the initial presentation. We report a 16-year-old boy who repeatedly presented with debilitating and alternating polyarthritis, diagnosed and treated as juvenile gouty arthritis after thorough clinical assessment and basic laboratory investigations in a resource-limited primary care clinic.

Published: December 2020

Airway foreign body aspiration (FBA)is a frequent problem that affects young children, present with acute respiratory distress and cough followed by sudden chocking. Prompt identification and early treatment can save the child from a life-threatening emergency.Delayed diagnosis due to lack of history and clinical suspicion may lead to permanent lung damage, which may be a curse for a lifetime.We share an experience of a 4½-year-old boy who presented with suppurative lung disease was associated with neglected FBA. Early diagnosis and intervention canprevent,and ultimately reduce long-term morbidity and mortality, along with improving the better outcome regarding FBA.

Published: December 2020

Present work describes the isolation and morphological identification of endophytic fungi from Phyllanthus niruri L. including their chemical and bioactivity screening. Two isolated and purified endophytic fungi with the internal strain numbers PNRE and PNLE were taxonomically identified as Colletotrichum sp. and Fusarium sp., respectively. Preliminary chemical screening of the fungal extracts through thin layer chromatography (TLC) revealed the presence of various components. PNLE showed significant antifungal activity against the fungi Aspergillus niger (24 mm) and Aspergillus flavus (20 mm). Extracts of PNRE and PNLE gave significant cytotoxic activity with LC50 values of 1.08 μg mL-1 and 1.05 μg mL-1, respectively in the brine shrimp lethality bioassay. PNRE extract showed mild scavenging of DPPH with IC50 value of 96.06 μg mL-1 during antioxidant activity screening. Crystal formation was observed in the crude PNRE fungal extract which was purified using methanol/dichloromethane (0-20%) to obtain pure white crystal and the structure was elucidated by NMR (1H NMR and 13C NMR) spectroscopic analysis to be confirmed as ergosterol. Since isolated fungi showed promising antifungal and cytotoxic activities, the crude extract of endophytic fungi of P. niruri could be considered as a promising source for isolation of potential bioactive compounds.

FACTORS AFFECTING THE PROFESSIONAL SATISFACTION OF GRADUATE TEACHERS IN THE DENUWARA EDUCATION ZONE IN SRI LANKA
Authors: W.M.S.WANANSINGHE
Published: January 2021

This research was conducted using a survey method with the primary objective of uncovering the factors that affect the professional satisfaction of a teacher. Seven hundred teachers from 1AB and 1C schools belonging to the Denuwara Zonal Office in the Central Province of Sri Lanka were randomly selected to collect data through questionnaire. Maslow's theory of interests was used as the theoretical basis. According to the data obtained from the questionnaires, the teacher-student relationship was the leading factor affecting the professional satisfaction of teachers; salary was presented as the second, while the leadership given by the principal was the third most important factor. It was clear from teacher feedback that internal and external supervision was not an important factor in professional satisfaction. Factors such as congestion in the classroom, shortage of teachers, available physical and human resources as well as other facilities, curriculum, parental support and community relations were revealed as unsatisfactory factors. It was also found that there is a significant difference in the analysis depending on the type of teacher response degree. Thus, it can be concluded that the teacher-student relationship and salary factors have a positive effect on the professional satisfaction of graduate teachers. Recommendations have been made to bring school alumni to school regularly and to increase teachers' salaries.
