Authors: Sirojudin Didin 
Published: July 2021

Pendidikan merupakan faktor yang sangat esensial dalam kehidupan manusia, karena pendidikan disini adalah proses sosialisasi yakni manusia harus mampu menterjemahkan konsep pendidikan dalam realitas kehidupan untuk mewujudkan tujuan pendidikan tersebut dibutuhkan adanya lembaga pendidikan yang respek terhadap persoalan dan kebutuhan masyarakat yang terus berkembang. Keberadaan Pendidikan Agama Islam di SMP Negeri 3 Peterongan Jombang belum banyak mengubah keadaan. Disebabkan karena terjadinya sistem dikotomi pendidikan, di sebabkan pelajaran umum yang menomorduakan Pendidikan Agama Islam, sehingga guru agama kehilangan nyali untuk terus mengembangkan strategi Pendidikan Agama Islam, kalaupun terkadang potensi itu ada. Dalam pembelajaran sehingga anak didik jelas dengan mata pelajaran yang dianggap menoton dan tidak menoton sehingga mengakibatkan tidak berhasilnya sebuah pembelajaran. Jadi perlu adanya suatu bentuk strategi yang handal, supaya pelajaran Pendidikan Agama Islam di sekolah umum menarik minat siswa. Berbicara mengenai strategi pembelajaran PAI di sekolah umum itu tentunya tidak cukup dengan satu strategi, harus ada tidak lanjud dan harmonisasi hubungan antara guru agama dengan guru umum serta masyarakat setempat.

Diffusing Entrepreneurial Innovation and Tourism: An Empirical Evidence of Permaculture
Authors: Lucky Umeh Azubuike , De Guzman Leilani I. , Fadare Stephen Ayoade 
Published: July 2021

Entrepreneurial innovation and tourism are essential factors in the economic growth of a rural agrarian area. This paper's concept is from Schumpeterian creative destructions' philosophical idea to shift rural communities' mentality from the product-based economy to diverse tourism entrepreneurship. In achieving and sustaining the development of permaculture as a platform for rural agritourism, the social capital theory of collectivism was employed to foster the development that would deliver socio-cultural, environmental, and economic benefits to all stakeholders in the community. This paper employed a descriptive research design to analyze the diffusion of entrepreneurial innovation and tourism systematically; also, to interpret the community's attitude towards the diffusion of permaculture for agritourism. Furthermore, interviews were conducted with the key informant group among the women organization. The paper subjected its participants’ through a non-probability sampling method using cluster sampling in the three barangays of the municipality of Bokod, Province of Benguet. The study results show that the respondents were willing to accept the permaculture for tourism and were willing to commit time to develop and manage the Permaculture project. They were motivated to accept and to participate in the project because they knew the values and benefits that permaculture would bring to the community. Also, while answering contingency valuation questions, the respondent thought about the value and benefits the project would bring. This study will enable communities to develop agritourism through permaculture landscapes in the rural community and, help policymakers in planning sustainable projects to support the community in entrepreneurial innovation.

Published: July 2021

The Internet of Things (IoT) is a key developing innovation aimed at linking objects via the Internet. While, Software Defined Networking (SDN) is another modern network- ing domain intelligence innovation that increases network effi- ciency and enhances security, reliability, and protection through dynamic software programs. In this paper, we proposed a distributed secure SDoT-NFV architecture for smart cities with Network Function Virtualization (NFV) implementation. We integrated highly protected SDN that delivers better network ef- ficiency, protection, and privacy results. It also secures metadata within each layer as well as payload. In addition, this architecture attempted to implement a more efficient method for constructing a cluster via SDN. Moreover, SDN-IoT with the NFV ideas brings benefits in terms of energy conservation and load balancing to the relevant fields. In addition, several distributed controllers have suggested enhancing accessibility, integrity, anonymity, con- fidentiality, and so on. We also implemented an energy-efficient Cluster Head Selection (CHS) algorithm to make use of our proposed architecture. The network offers greater protection of each network layer as opposed to the traditional network in the proposed architecture. Lastly, we analyze the efficiency of the proposed architecture with different network parameters (throughput, RTT, and Time sequence) for smart cities.

Published: July 2021

The study was conducted to analyze the groundwater potential zones in the Eastern part of Kushtia district. Secondary data collected from Bangladesh Agriculture Development Board Corporation (BADC) and borehole data of 119 locations have been processed, analyzed and interpreted for studying the hydrogeological properties. The sub-surface groundwater-bearing sequence of the area up to the depth of 97 m have been classified into two main hydrostratigraphic units- aquitard and aquifer, consisting of clay-silt-sand and sands of different granular respectively. The 18-30 m thick aquitard is covering a major part of the study area. The thickness of main aquifers is varying from 0.9-30 m and 27-67 m consisting of fine-medium to coarse sand. The yield potential index is 1.3-13.0. However, from the obtained results, it can be concluded that the area is suitable for groundwater potentiality.

Role of Climatic Conditions on the Incidence of Varicella in an Out-patient Clinic of a Tertiary Care Pediatric Hospital at Dhaka
Authors: Hussain Mahfuza , Amin Md Nurul , Islam Md Rafiqul 
Published: July 2021

Background & objective : Chicken pox or varicella is a disease of both tropical and temperate zones bearing a complex-relationship with climatic variables, like temperature, rainfall and relative humidity, wind velocity and so on. As no study has, by far, been conducted to relate its occurrence with these climatic variables in Bangladesh, this study was intended to explore the effect of weather conditions on the incidence of varicella in Dhaka city of Bangladesh.
Methods: The present cross-sectional study obtained data of 172 varicella cases from the records of the daily register of Out-patient Department of Dhaka Shisu Hospital, Dhaka between January 2018 to December 2019. According to the study protocol a child was diagnosed as having varicella or chicken pox who had a history of short febrile illness accompanied by a pruritic vesicular eruption (on the face and trunk)) of the skin and mucous membranes which ultimate weeps out and crusts. Total number of cases treated monthly at Out-patient Department (OPD) during the period was also recorded. Climatic data were provided by Bangladesh Meteorological Department, which among others, included monthly average temperature, relative humidity (RH) and amount of rainfall or precipitation. While the outcome variable was monthly number of varicella cases, the predictive variables were average temperature, humidity and rainfall during the study period.
Result: Over 70% of children were 1-10 years old with median age of the children being 5.5 years (range: < 1 month -14 years). Boys were a bit higher (54%) than the girls (46%). A seasonal pattern of chicken pox was seen with clustering of cases between mid-February to mid-April (spring season) with two peaks – one in February and another in April, when monthly average temperature, total rainfall and humidity all were at their optimum. The peak incidences of chicken pox cases during the spring both in 2018 and 2019 as correlated with climatic data of the same period, it is seen that the prevailing weather then was optimum-average temperature was 23°C, average precipitation was 20-25% of the total annual precipitation and relative humidity was around 65%.
Conclusion: The study concluded that majority of the varicella cases occur under ten years of age and boys are a little more susceptible to have the infection than the girls. A seasonal pattern of chicken pox is clearly seen with clustering of cases between mid-February to mid-April (spring season) with two peaks when monthly average temperature, total rainfall and humidity all are optimally favorable for the multiplication of varicella zoster virus.

Background & objective: The present study was undertaken to justify the role of routine antenatal screening for syphilis using the Venereal Disease Research Laboratory (VDRL) test in Bangladeshi pregnant women.
Methods: The study was carried out in the Department of Gynecology & Obstetrics Inpatient and Outpatient, Dhaka Medical College Hospital (DMCH) and selected Private Clinics over a period of 6 months between January 2016 to June 2016. Pregnant women attending at the above-mentioned places during the study period were the study population. A total of 371 women attending at antenatal clinic at OPD or admitted in the Inpatient Department of DMCH were consecutively included. The outcome variable was outcome of VDRL test.
Result: In the present study, the mean age of the pregnant women was 24.3 years. In terms of occupation, housewife comprised the main bulk (78.8%). About 64% were multigravida and 60% were primipara. Of the 371 pregnant women subjected to VDRL test, only 4(1.1%) exhibited reactive. About one-third of the women had history of past abortion. Of them two-thirds had experienced abortion once. Of the aborted cases 57% were spontaneous and 43% induced. Ten percent of the women gave the history of delivering dead baby. Three-quarters of the dead babies were fresh, 22.2% had skin lesion and only one was macerated. Half of the women had history of vaginal discharge, 27.2% itching in vagina and vulva and 17% dysuria. However, very few husbands had dysuria, pus discharge through urethra or ulcer in the genital region. About 10% of women gave the history opthalmia neonatrum in their children born in the past. History of dysuria was rare (0.8%), but pus discharged from urethra of their husbands was 12.1%. HbsAg was found positive in 5(1.3%) cases and pus-cell in urine in 41(11.1%) cases.
Conclusion: The study concluded that pregnant women with VDRL test positivity in Bangladeshi population are low and, as such, the role of routine antenatal screening for syphilis with VDRL test should be re-considered.

Published: July 2021

Objective: The objective of the present study was to see the effect of magnesium in preventing cardiac arrhythmias in patients undergoing coronary artery bypass grafting (CABG) surgery.
Methods: This study was carried out in the Department of Anesthesia, Analgesia and Intensive Care Medicine (Cardiac Anesthesia Wing) of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka who underwent CABG surgery under general anaesthesia. A total of 60 patients scheduled for CABG were consecutively selected and were randomly divided into study group and control group. Patients aged 35-70 years irrespective of sex, ASA grade I & II, NYHA functional class I & II and ejection fraction 35-65% were included in the study. The study group was treated by vecuronium, fentanyl and magnesium sulphate infusion, while the control group was treated by vecuronium and fentanyl infusion. The demographic variables, preoperative clinical characteristics, peroperative variables and haemodynamic findings were observed at different time intervals.
Results: The mean ages of the study and control groups were 51.0 ± 6.9 years and 53.8 ± 6.2 years respectively. Males demonstrated their predominance in both magnesium (83.3%) and control (76.7%) groups. The distribution of preoperative confounding factors like diabetes, previous MI, hypertension and ejection fraction were not statistically different between the study groups. Two-thirds (67.7%) of the patients in magnesium group and 53.3% in the control group required 3 grafts. Number of 4 grafts in magnesium and control groups was 20% and 30% respectively and that of 2 grafts was 13.3% and 16.7% respectively. In the study group, out of 30 patients, 3(10%) developed arrhythmia, while in the control group out of 30 patients, 5(16.7%) developed arrhythmia (p = 0.353).The haemodynamic parameters in patients receiving magnesium were more stable during the whole period of observation.
Conclusion: The findings of the study suggest that magnesium could reduce the development of arrhythmia to an acceptable level in patients undergoing beating heart CABG surgery. However, further study with large sample is recommended to achieve a conclusive remark.

Authors: Khan Md Mohiur Rahman , Hassan Muhammad Raaqul , Rahman Fahmin , Chowdhury ATM Mowladad 
Published: July 2021

Background & objective: Renal Cell carcinoma (RCC) accounts for 2 – 3% of all malignant adult neoplasm and is associated with a mortality of 30-40%. It is not well responding to the conventional chemo and radiotherapy and in early stages of the disease,radical nephrectomy is the treatment of choice. A detailed clinoco-pathological study is of paramount importance to understand its management. The aim of this study is to describe the clinical characteristics and histopathological spectrum of RCC.
Methods: This Cross-sectional descriptive study was carried out in the Department of Urology, BIRDEM General Hospital and Dhaka Medical College Hospital over a period 10 months from June 2013 to March 2014. All FNA positive renal cell carcinomas were included in the study. A total of 100 cases of RCC irrespective of age and sex were selected and their anatomical distribution, clinical presentation, stage at presentation and histopathological type were studied.
Result: The peak incidence of renal cell carcinoma was observed to be between 4th and 5th decades of life. The median age was 52.3 years. A male predominance was observed in the series with male-to-female ration being 3:1. Two-thirds (67%) of the patients were diagnosed incidentally, 23% presented with pain and heamaturia and 10% with loin mass. A sizable proportion of the patients was found to have paraneoplastic syndrome [raised ESR (60%), hypertension (50%), anaemia(40%), weight loss (15%), pyrexia (2%)and hypercalcamia (2%)]. Tumours mainly involved the right kidney in its upper pole (55%). In 60% cases the size of the tumour extends between 3-7 cm. Most of the tumours were diagnosed at Robsing stage II (66%). Histopathological diagnosis showed that 70% had clear cell sub-type RCC, 20% papillary sub-type, 5% chromophobe and 5% othersub-types.
Conclusion: Renal cell carcinoma generally occurs in older persons with a male preponderance, It occurs mainly in right kidney preferably in the upper pole. Patients usually present with paraneoplastic syndrome (raised ESR, hypertension, anaemia, weight loss etc.). The typical triad of pain, flank mass and microscopic hematuria is rare. Two-thirds of the RCC are diagnosed incidentally at Rosing stage-II and majority is of clear-cell sub type.
