Surgical intervention is safe, feasible, and effective in tubercular tracheobronchial stenosis
Authors: Pulle Mohan Venkatesh , Asaf Belal Bin , Puri Harsh Vardhan , Bishnoi Sukhram , Kumar Arvind 
Published: April 2021

Objectives:
Posttubercular tracheobronchial stenosis is a troublesome sequela of tracheobronchial tuberculosis. Surgical resection is the treatment of choice when repeated bronchoscopic dilatations fail. Herein, we aim to present our surgical experience in the management of this problem and also to evaluate factors affecting the surgical outcomes.

Materials and Methods:
This is a retrospective analysis of a prospectively maintained database at a dedicated thoracic surgical unit in New Delhi, India, over 8 years. An analysis of demographic characteristics, perioperative variables including complications were carried out. The occurrence of postoperative complications, and/or hospital stay of >7 days was considered as “poor” surgical outcomes. Various parameters were analyzed to assess the factors predicting surgical outcomes.

Results:
A total of 20 patients were surgically managed in the study period. Two patients had tracheal stenosis. The left main bronchus was involved in 16 patients. In these 16 cases, 12 cases underwent lung preserving surgery (bronchial sleeve resection and sleeve lobectomy) and rest of 4 cases required pneumonectomy. All postoperative complications occurred in 5 (25%) patients. Prolonged air leak was the most common postoperative complication. On univariate analysis, surgical outcomes were poor in patients who had longer duration of symptoms (P = 0.03) and with >2 episodes of preoperative balloon dilatations (<0.001). On multivariate analysis, “total number of dilatations <4 times,” emerged as a significant predictive factor for lung preservation surgery.

Conclusions:
Surgical intervention is safe, feasible, and effective in tubercular tracheobronchial stenoses which fail to respond to bronchoscopic interventions. Early referral for surgery favors lung preservation.
The Perception of Rural Households on Climate Change Effect on Rural Livelihoods in Lake Victoria Basin
Authors: Wabwire Evans Odhiambo , Mukhovi Stellah , Nyandega Isaiah Ang’iro 
Published: April 2021

While the science of climate change is well investigated across most disciplines, people’s perception of climate change effects has not been well addressed. This paper sought to address the question of climate change perception and the effect of climate change on rural household livelihoods within the Lake Victoria Basin of Kenya. The study relied on households’ perception on the effect of climate change on the areas of agriculture, and food security, water, and energy supply. Multistage sampling was applied to select 539 households from four eco-ecological zones. The study revealed that most households presented localized explanations of climate change, which included: frequent and prolonged droughts, variations in rainfall onset and cessation, increased temperatures, an increased strong wind episode. Some households perceived climate changes effects resulted into a decrease in crop yield, resulting in increased household food insecurity, while some perceived water stress at household level, but mainly for those who relied on surface water, well water, borehole, and the natural spring. In addition, some of the households perceived shortage in energy sources, particularly hydroelectric power was said to be sensitive to the changes in climate. These perceptions were based on households’ experiences, and partially the results were found to be consistent with physical science of climate change. The paper therefore recommends the need to harmonise household perception with the climate change policy in order to address emerging challenges of climate change at the local level, create more climate change awareness supported through a comprehensive climate change action plan on country’s preparedness of extreme climate events at household level.
Multiple Linear Regression Model for Estimating the Price of a Housing Unit
Authors: Boye P. , Mireku-Gyimah D. , Okpoti C. A. 
Published: April 2021

This paper uses the respective unit costs, over fifteen (15) years, of selected Housing Unit Major Components (HUMC): cement, iron rods, aluzinc roofing sheets, coral paint, wood and sand, to develop Multiple Linear Regression Model (MLRM) for determining Housing Unit Price (HUP) for one-bedroom and two-bedroom housing units. In the modeling, the Ordinary Least Squares (OLS) normality assumption which could introduce errors in the statistical analyses was dealt with by log transformation of the data, ensuring the data is normally distributed and there is no correlation between them. Minimisation of Sum of Squares Error method was used to derive the model coefficients. The resultant MLRM is: Ŷi MLRM = (X'X)-1 X'Y(xi') where X is the sample data matrix. The specific model for one-bedroom housing unit is loge (HUPMLRM)1-Bed = 1.017 – 2.225 x 10-5 x CC + 2.512 x 10-6 x CS + 6.016 x 10-4 x CIR + 1.985 x 10-4 x CR + 5.694 x 10-4 x CP -7.437 x 10-4 x CW and that for two-bedroom housing unit is loge (HUPMLRM)2-Bed = 5.760 – 7.501 x 10-7 x CC + 2.935 x 10-6 x CS + 1.898 x 10-3 x CIR + 6.695 x 10-4 x CR - 9.157 x 10-3 x CP +6.136 x 10-3 x CW, where CC, CS, CIR, CR, CP and CW are costs of the total quantity of cement, sand, iron rods, roofing, paint and wood respectively. The MLRM was validated by using it to estimate the known HUP in the 15.5th year. From the results, the percentage absolute deviations of the estimated HUP from the known HUP are 1.27% and 2.02% for one-bedroom and two-bedroom housing units respectively, which are satisfactory. The novel approach presented in this paper is a valuable contribution to the body of knowledge in modeling. Keywords: Multiple Regression Analysis, Housing Unit Major Components, Housing Unit Price
Comparative Study of Mathematical Models for Ghana’s Gold Production
Authors: Appiah S. T. , Buabeng Albert , Odoi B. 
Published: April 2021

Sigmoid functions were used to approximate the cumulative gold production in Ghana. The functions examined were the logistic, Gompertz, Gaussian, Probit and the Hill, which were then used to predict into the future. Although all the five approximated models gave a good estimation of the reality, the Gompertz function was identified to give the best approximation of the observed trend of gold production in Ghana. The model was selected based on its high proportion of variance explained (R2 = 0.9402) as well as having the least value in terms of error (RMSE) and information loss (AIC). The model suggested that gold production could escalate to a level of 7040813 Oz in the future. It also showed that, industrial scale production of gold should be possible even after the year 2050 provided the current upward trend of gold production in Ghana continues.

Published: April 2021

Many plants have the ability to take up gold from soils and accumulate them in their tissues. Their concentrations and distributions reflect the nearby gold deposits masked by complex regolith. The 50 vegetation samples collected at Pelangio Tepa concession recorded low and subtle gold (Au) concentrations of 0.2 to 10.4 ppb at Pokukrom target, 0.3 to 28.3 ppb at Nfante East target and 0.1 to 1.7 ppb at Subriso target. Each target area had different concentration populations enough to distinguish the anomalous areas from the background contrary to Au-geochemical expressions derived from the gold in soils. So many uncertainties were placed on the soil-Au-geochemistry because the defined anomalies were not strong and generally appear patchy, weak and subtle that led to the assumption of no associated bedrock mineralisation. The gold in plant samples confirmed the Pokukrom anomaly that has been drilled and known to relate to underlying mineralisation. Much better and robust anomaly was defined by the biogeochemical Au data in plants sampled and analysed for Au at Nfante East target and isolated high patchy anomalies were identified at Subriso area. The case study at Pelangio Mamfo project reveals and recommends the significant application of biogeochemistry in mineral exploration particularly in the field of gold prospecting at the regional exploration stage and endorses it as being practically feasible in regolith-dominated terrains where regolith-landform modifications may impact on the true geochemistry in anomaly delineation.

Multivariate Analysis of the Effect of Climate Conditions on Gold Production in Ghana
Authors: Takyi Appiah Sampson , Buabeng Albert , Dumakor-Dupey N. K. 
Published: April 2021

The change in climatic conditions and its catastrophic effect on mining activities has become a source of worry for mining industries and therefore needs due attention. This study examined the effect some climate factors have on gold production in Ghana. First, a direct Multiple Linear Regression was applied on the climate factors with the aim of determining the relative effect of each factor on gold production which exhibited a time series structure. The consequence is that, the estimates of the coefficients and their standard errors will be wrongly estimated if the time series structure of the errors is ignored. In order to eliminate these deficiencies and better understand the effect of these climate factors on gold production, regression with ARIMA errors technique was employed after its appropriateness has been tested. The model was then compared in terms of prediction accuracy which resulted a MAPE of 9.78%. It was concluded that, gold production in Ghana is positively related to Temperature whilst negatively to Rainfall and Precipitate. It was recommended that mine operators in Ghana could base on this analysis to optimise their production planning and scheduling.

Toward Consensus in Assessing Upper Limb Muscle Strength and Pinch and Grip Strength in People With Tetraplegia Having Upper Limb Reconstructions
Authors: Dunn Jennifer A. , Koch-Borner Sabrina , Johanson M. Elise , Wangdell Johanna 
Published: April 2021

Objectives:
To reach agreement on standardized protocols for assessing upper limb strength and grip and pinch force for upper limb reconstructive surgery for tetraplegia.

Methods:
Selected members of an expert panel composed of international therapists formed at the 2018 International Congress for Upper Limb Surgery for Tetraplegia conducted a literature review of current practice that identified gaps and inconsistencies in measurement protocols and presented to workshop attendees. To resolve discrepancies, a set of questions was presented to workshop attendees who voted electronically. Consensus was set at 75% agreement.

Results:
For manual muscle testing, consensus was reached for using the Medical Research Council scale, without plus or minus, and the use of resistance through range when testing grade 4 and grade 5 strength. Pectoralis major and serratus anterior should be routinely tested, however there was no consensus on other shoulder muscles. Grip and pinch strength should be tested according to the American Society of Hand Therapists positioning. For grip strength, either the Jamar or Biometrics dynamometer expressed in kilograms should be used. For grip and pinch strength, three measurements should be performed at each testing. No consensus was reached on a device for pinch strength.

Conclusion:
This work is an important step to enable comparable data in the future. Further consensus methods will work toward developing more comprehensive guidelines in this population. Building international consensus for pre- and postoperative measures of function supports objective evaluation of novel therapies and interpretation of multicenter studies.

PEPERANGAN NABI MUHAMMAD SAW. DAN AYAT-AYAT QITÂL
Authors: Maimoen Abdul Ghofur 
Published: April 2021

Persoalan perang dalam masyarakat Islam belakangan ini kembali menjadi problematis karena kini muncul kecenderungan kelompok-kelompok yang memahami perang sebagai sebuah gerakan ofensif atau menyerang. Pemahaman itu sangat mungkin didasarkan atas pembacaan terhadap ayat-ayat qitâl secara parsial. Kajian ini mencoba membaca ayat-ayat qitâl atau perang dari perspektif Qur’ani secara holistik –tidak hanya melalui pendekatan tafsir tapi juga Ushul Fikih–, yang dibingkai dengan pembacaan terhadap sejarah Islam, terutama dalam kaitannya dengan sejarah perang Nabi Muhammad dan juga dilihat dari perspektif prinsip-prinsip dakwah Islam itu sendiri, karena dengan begitu pembacaan terhadap ayat-ayat qitâl baru akan menjadi komprehensif dan tidak lagi sepotong-potong.

Key words: ayat-ayat qitâl, perspektif Qur’ani, sejarah perang Nabi Muhammad, prinsip-prinsip dakwah Islam.

Majelis Tafsir Al-Qur’an (MTA) recently claims that they don’t make exegesis of Al-Qur’an. But this opinion seems like different from the reality. It is fact that MTA has an exegesis book and continues to make exegesis of Al-Qur’an. This article describes the history of development and MTA exegesis dynamics. Since the exegesis was taught by the founder of MTA, Abdullah Thufail, MTA’s exegesis isn’t static. But has got many corrections, change, until revision. It is predicted that MTA’s exegesis is going to get development and continual.

KOREKSI MUḤAMMAD ṬĀLIB ATAS TERJEMAH AL-QUR`AN KEMENAG RI: (UJI VALIDITAS)
Authors: Fuadin Ahmad 
Published: April 2021

In his Koreksi Terjemah Harfiyah al-Qur`an, Muḥammad Ṭālib, the amīr of the Majelis Mujahidin Indonesia, accuses the official Qur’anic translation by the Indonesian Ministry of Religion for containing digression and at the same time- supporting radicalism. This article wants to describe and examine Ṭālib’s argumentations. It finds that Ṭālib’s inappropriate methodology lets him criticize the manuscript over-confidently. First, He has only read it partially and could not catch the whole meaning it provides. Second, ignoring the fact that the exegetes whom he was referring to may provide alternatives for one particular word, Ṭālib has uncarefully treated his sources.Key word: Qur’anic translation, Indonesian Ministry of Religion, Muḥammad Ṭālib, examine validation
SEMIOTIKA DAN RELEVANSINYA DENGAN KAJIAN AL-QUR’AN
Authors: Kasyful Humam Abdul Wadud 
Published: April 2021

Abstract
Considering that the Qur'an consists of a series of Arabic letters arranged in strings of words and sentences, is a medium where signs are messy, so one approach that seems interesting and relevant is the semiotic approach which examines how sign works and its function in the text of the Qur'an. Semiotics is a discipline that examines signs found in society. Meanwhile, the Al-Qur'an using language as a medium is fertile ground for semiotic studies. In the Qur'an, there are signs that their meanings can be studied by using semiotics. The Qur'an has basic units called verses (signs). Signs in the Qur'an are not only small parts of the elements, such as sentences, words or letters, but the totality of the structures that connect each element is included in the category of signs of the Qur'an. This shows that the entire form of the Qur'an is a series of signs that have meaning.

KONSEP KESETARAAN GENDER DALAM ISLAM
Authors: Rohmatul Izzad  
Published: April 2021

Abstract
From the 20th century to the 21st century, feminist model of interpretation has been developing rapidly. The majority of feminist interpreters, both men and women, criticize the centrality of men in interpreting the Qur'an.They emphasize the argument that the interpreter's gender bias is still dominated by men, most of which have shaped the paradigm of understanding the Qur'an and Islam in general. In contrast to secular feminists, Muslim feminist scholars do not reject Islam itself. Instead, they refer to the Qur'an and the Prophet's Sunnah to support their claim that the Qur'an needs to be reinterpreted. This research specifically tries to study and explore the concept of gender equality in Islam, especially in the perspective of Muhammad Syahrur's hermeneutic thinking. This research analyzes the real relationship between men and women in Islam, whether the views of past scholars are still relevant in positioning the status of men and women. In other words, this research tries to carry out a contemporary reading of the gender equality concept in Islam, which specifically refers to Muhammad Syahrur's hermeneutic. On this basis, this study uses an analysis-hermeneutic approach. Through Syahrur's hermeneutics, the researcher critically analyzes the relationship between men and women in Islam, and carries out a contemporary reading of it. Therefore it is expected to be able to produce a new thought product about gender in Islam that is more contextual and in accordance with the dynamics of the times.
Keywords: feminism, gender equality, al-Qur'an hermeneutics.
KAJIAN TERHADAP RASM DALAM NASKAH MUSHAF AL-QUR`AN MADURA
Authors: Luluk Asfiatur Rohmah  
Published: April 2021

Muslim’s approach to the holy book al-Qur ʻan is expressed in various activities, reading, memorizing, writing, transcribing, and others. The copying of Al-Qur ʻan has been being strictly controlled by the rasm used, rasm uthmani and rasm imla'i, and the copies has been being maintained by the museum, pesantren, collectors, heirs and others with various purposes and interests. This paper examines the manuscripts of the Mushaf al-Qur ʻan H. Habibullah from Konang Village, Bangkalan, Madura from the aspect of using rasm, vowels and punctuation. The result of this study is that the copying of the manuscripts of the Mushaf al-Qurʻan H. Habibullah is inconsistent in applying the rules for writing rasm uthmānī and rasm imlā'i from the rules for discarding letters, adding letters, writing hamzah, changing letters and writing punctuation (harakat). The writing of this Mushaf manuscript also came out of the corridors of the rules for writing rasm uthmānī and rasm imlā'i. This inconsistency was influenced by the absence of a reference basis for writing the Mushaf at that time, as well as the unfamiliarity of Nusantara Muslims with the Arabic language rules, nahw-ṣarf.
Keywords: Consistency, Manuscripts of the Al-Qur ʻan, Madura, Rasm
ANALISIS SEMANTIK KATA ZAWJ DALAM AL-QUR’AN
Authors: Marjiatun Hujaz  , Nur Huda  , Syihabudin Qalyubi  
Published: April 2021

This study aims to examines the meaning of zawj in al-Qur'an. This research is a qualitative research using descriptive-analysis method. Descriptive-analysis method aims to analyze the zawj’ word in the Qur'an. The meaning of zawj in the Qur'an is very vareative. In the Koran with various derivations, the word zawj is 21 derivations contained in 72 verses of 43 surahs and is mentioned in 81 times. The researcher used the semantic analysis of al-Qur'an which was initiated by Toshihiko Izutsu who tried to address the world view of Qu'ran (weltanschauung) through semantic analysis of the vocabulary and key terms in the Qur’an. This research concludes that the basic meaning of the word zawj is something that is not singular or something that has an equivalent. Zawj can be interpreted as: a husband in the surah (al-Mujādalah [58]: 1;wife in the surah (al-Baqarah [2]: 35; a partner, namely Allah created all beings in pairs (az-Dzariyat [51]: 49;animals are male and female pairs (al-An'ām [6]: 143), plants (al-Syu'arā [367]: 7); and groups (al-Wāqi'ah [56]: 7. In the pre- Qur'anic, the word zawj is defined as a rug. In the Qur'anic period it is divided into two, namely Mecca and Medina. The Mecca period has a close meaning with the sign of the greatness of Allah and the pleasure that Allah gives. The Medina period contains the laws of separation. In the post-Qur'anic period, the word zawj describes gender equality, that men and women are the same components without being differentiated, so that there is a harmonious life in pairs.
