Регулирование социально-трудовых отношений в системе социального партнерства на промышленных предприятиях Карагандинской области
Authors: А. А. Бейсенова  , Е. Н. Дзюренич
Published: March 2022

В данной статье рассматриваются вопросы регулирования социально-трудовых отношений на промышленных предприятиях Карагандинской области, на основе проведенного социологического исследования. Как показывает мировая практика конструктивное взаимодействие между субъектами трудовых отношений возможно на основе социального партнерства, которое и стало развиваться во многих отраслях промышленности и занятости. Важно отметить, что развитие института социального партнерства на промышленных предприятиях значительно отличается от других сфер деятельности. Тяжелые и вредные условия труда, труд, связанный с риском для здоровья и жизни рабочего, определяют объем социальных обязательств работодателя. Как показывает практика, перед профсоюзами, рабочими всегда встает проблема преодоления противоречий с работодателем по вопросам оплаты труда, ее индексации с учетом инфляции, расширения пакета социальных гарантий, выполнения условий коллективного договора руководством предприятия. Посредством вмешательства государства в переговорный процесс стороны приходят к консенсусу, тем самым подтверждая, что социальная ответственность предпринимателей остается на низком уровне. В статье приводятся некоторые результаты социологического исследования проведенного с помощью массового опроса и глубинных интервью на промышленных предприятиях Карагандинской области.

Published: March 2022

Indian culture considers Sanskrit as “Devabhasha”(language of God). It was the dominant language of Indian writings. Kalidasa is the greatest Sanskrit poet. His all compositions are immortal. He shows a new path to the world literature. Kalidasa was a great scholar and he showed his genius through his works. His compositions show his knowledge on the Vedas, the Puranas, the Ramayana, the Mahabharata, the Alamkarashastra, the Vyakarana, Philosophy etc. In the drama Malavikagnimitra also the poet very beautifully delineated the female characters. This is about the love story of Malavika,princess of Vidarbha and Agnimitra, the King of Vidisaha. The heroine of the nataka is princess of Vidarbha, Malavika. Queen Dharini is the symbol of ideal Indian woman. She is very chest woman. She can understand the fickle minded king Agnimitra. Iravati is a beautiful woman. She is a conceited beloved. On Malavika, she is very jealous. Because of jealousy, She scolds Vidusaka and Malavika’s friend. She becomes very upset when she sees that king is charmed by Malavika. Madhavasena’s minister Arya Sumati’s sister is Panditakausiki.When her brother lost his life in the hands of dacoits, she feels very sad and becomes a ‘sanyasi’. In this article we are going to discuss about the female characters of Malavikagnimitra.

This research, Enhanced Security Framework for Internet Banking Services is aimed at developing a suitable framework, a system based on consolidating two algorithms, improved RSA with LSB steganography capable of providing secure transmission of customer Internet banking credentials as this is imperative since the online transactions are carried out using public networks that are vulnerable to varying forms of cyber threats and attacks on data confidentiality, integrity and authenticity. In conducting this research, a thorough analysis of the existing banking system used by most banks such as First bank, Stanbic IBTC and UBA, the FINACLE 10.8 and intellect(TM) PRIVACY security system used by POLARIS bank was carried out in order to ascertain the existing security features while at the same time, reviewing the existing, current Internet banking security models in a bid to concretely establish the gaps filled by this research. The data gathered for this research were collected using the key informant interview method (KIIM), visiting banks IT unit and observation of operational procedures and other technicalities as regards Internet security. Lecture notes, newsletters and journal articles relating to Internet banking security were thoroughly reviewed.  It was however found that the existing applications were unable to stop offline credential stealing attacks, were also vulnerable to malicious attacks when credentials are stored on customer PCs. Hence, the use of steganography in this research to consolidate cryptographic algorithms (beginning from the use of PKI-cards on card readers). In building the system, the OOAD approach was used with tools such as Class Diagram, Sequence Diagram, DFDs, and UML use cases to capture the system functionalities in a bid to come up with a successful design. MATLAB R2015a was used to process images imported from JAVA platform and analysis carried out on five (5) standard gray USC-SIPI images of size 512 × 512tiff formats as data sets selected to conceal customer data after encryption by the RSA technique yielding very high PSNR and very low MSE values as required for a secure credential transmission.
The Transition from Short- to Long-Term Marine Corrosion of Carbon Steels: 2. Parameterization and Modeling
Authors: Melchers Robert E. , Jeffrey Robert
Published: March 2022

Previously, it was suggested that in the bi-modal model for corrosion loss as a function of exposure period the instantaneous corrosion rate increases by a factor of about 4 through the transition phase from mode 1 to mode 2. Recent experimental observations (from Part 1 [Melchers and Jeffrey, Corrosion 78, 5 (2022): p. 415]) and other experimental observations covering a range of corrosion influencing parameters closely support this value. The reason for it is examined through a model of the development of corrosion through the transition zone, based on interpretations of the data presented in Part 1. It is shown that pitting plays a crucial role in lowering local pH conditions and permitting transitioning of the corrosion process from oxygen reduction (in mode 1) to hydrogen evolution (in mode 2) as the thermodynamically possible cathodic reaction. In both cases, the rates of corrosion are controlled by diffusion considerations, not electrochemical kinetics. This also permits a theoretical basis for the observed ratio of around 4. Further, eventual long-term corrosion, usually observed as close to a linear trend in time, is proposed as representable a system in quasi-static equilibrium, involving both the hydrogen evolution reaction at the corrosion interface and loss of ferrous ions from the external face of the rust layers.

Diagnostic performance of chest computed tomography for COVID-19
in children: a systematic review and meta-analysis of clinical and computed tomography features in 987 patients
Authors: Ghoneim Mahitab , Eid Riham , Hamdy Nashwa , Shokry Doaa , Salem Mohammed A. , El-morsy Ahmed , H. Elmokadem Ali
Published: March 2022

Purpose

The outbreak of a new coronavirus is still spreading worldwide, affecting children and adults. However, COVID-19 in children shows distinctive characteristics in clinical and radiological presentation. We aimed to assess the diagnostic performance of chest CT and clarify the clinicoradiological CT features of COVID-19 among children with COVID-19.

Material and methods

Adhering to PRISMA-DTA guidelines, we searched databases (PubMed, Google Scholar, and Web of Science) to identify relevant articles. The search keywords were: “Chest CT” AND “COVID-19” OR “coronavirus” OR “SARS-COV-2” AND “Children” OR “Pediatric”. Published reports providing clinical and imaging findings of paediatric COVID-19 were included.

Results

Twenty-eight studies were included, with 987 patients. Most of the patients were symptomatic (76.9%; 95% CI: 69.2-84.7%), with fever being the most frequent manifestation (64%; 95% CI: 58.0-71.2%). Only 2.3% of the cases were critical, and mortality was reported in one case. The proportion of COVID-19 detected by chest CT among children is relatively high (658/987), with ground-glass opacity (GGO) being the most prevalent feature (52.5%; 95% CI: 40.5-64.7%). The pooled sensitivity of chest CT in all patients was 67%; however, it was different between symptomatic and asymptomatic patients (71% and 33%, respectively). The pooled specificity was (67%), which was calculated after considering the symptomatic PCR-positive patients as the gold standard.

Conclusions

Chest CT showed moderate pooled sensitivity and specificity among symptomatic children with COVID-19 and low sensitivity among asymptomatic children. This means that CT is not to be used as a screening tool or for confirmation of the diagnosis in children and should be reserved for specific clinical situations.

Reducing water consumption in low-cost housing areas in the eThekwini Municipality
Authors:   , Thakur Rookmoney
Published: March 2022

South Africa is facing a water crisis and local municipalities are finding it difficult to mitigate the gap between supply and demand. Although the government’s policy to allocate a basic supply of 9kl of free water per month to indigent communities is commendable, the rapid exhaustion of the free supply by low-income communities necessitating a tariff applied for additional water consumption, is concerning. Whilst this consumption-based tariff is used to encourage conservation, municipalities nevertheless face a revenue loss due to a non-payment culture. This study argues that behavioural change is more beneficial than punitive economic measures and seeks to develop a strategic intervention to assist the eThekwini municipality to promote water conservation behaviour in one low-income community, called Waterloo. The Theory of reasoned action (TRA) is used to identify the beliefs, attitudes and subjective social norms towards water conservation and the Nudge Theory is used to incentivise water users towards behavioural change. A mixed method exploratory sequential design method is adopted. The qualitative phase of the study consists of semi-structured interviews with eight key informants from government and the public sector; and four focus group discussions with 22 residents of the Waterloo community, to determine the factors that influence their water-use behaviour. Participation in this study was voluntary with confidentiality maintained. The data was recorded and transcribed to ensure credibility. The results were interpreted and analysed against existing literature using thematic content analysis. The quantitative phase of the study investigates the power of the TRA. Results from a survey comprising 304 residents indicate that low-income householders generally have very positive attitudes towards water conservation and saving practices, nonetheless these positive attitudes are not consistently translated into actual behaviour. In synthesising the results, three recurring key issues are identified, namely (1) access to knowledge; (2) community engagement as part of the solution; and (3) allocation of incentives. The key finding of study indicated that awareness of the current water situation itself may not motivate good water use behaviour. While participants had knowledge of water conservation practices, there was, however, a high amount of water consumption and high unaccounted water losses in the area. Therefore, nudging the community may be an ideal approach towards behavioural change. The thesis concludes by proposing a community-based behavioural framework, as a guideline for eThekwini to consider when designing conservation measures for low-income communities
Changing Ozone Sensitivity in the South Coast Air Basin during the COVID-19 Period

Published: March 2022

Abstract. The South Coast Air Basin (SoCAB), which includes the city of Los Angeles and is home to more than 15 million people, frequently experiences ozone (O3) levels that exceed ambient air quality standards. While strict regulation of O3 precursors has dramatically improved air quality over the past fifty years, the region has seen limited improvement in O3 over the past decade despite continued reductions in precursor emissions. One contributing factor to the recent lack of improvement is a gradual transition of the underlying photochemical environment from a VOC-limited regime towards a NOx-limited one. The changes in human activity prompted by COVID-related precautions in Spring and Summer of 2020 exacerbated these already-occuring changes in the O3 precursor environment. Analyses of sector-wide changes in activity indicate that emissions of NOx decreased by 15–20 % during Spring (April – May) and 5–10 % during Summer (June – July) relative to expected emissions for 2020, largely due to changes in mobile source activity. Historical trend analysis from two indicators of O3 sensitivity (the satellite HCHO/NO2 ratio and the O3 weekend/weekday ratio) revealed that Spring of 2020 was the first year on record to be on average NOx-limited, while the “transitional” character of recent Summers became NOx-limited due to COVID-related NOx reductions in 2020. Model simulations performed with base-case and COVID-adjusted emissions capture this change to a NOx-limited environment and suggest that COVID-related emissions reductions were responsible for a 0–2 ppb decrease in O3 over the study period. Reaching NOx-limited territory is an important regulatory milestone, and this study suggests that deep reductions in NOx emissions (in excess of those observed in this study) would be an effective pathway for long-term O3 reductions.
Interpretation of NO3–N2O5 observation via steady state in high-aerosol air mass: the impact of equilibrium coefficient in ambient conditions
Authors: Chen Xiaorui , Wang Haichao , Lu Keding
Published: March 2022

Abstract. Steady-state approximation for interpreting NO3 and
N2O5 has large uncertainty under complicated ambient conditions
and could even produce incorrect results unconsciously. To provide an
assessment and solution to the dilemma, we formulate datasets based on
in situ observations to reassess the applicability of the method. In most of
steady-state cases, we find a prominent discrepancy between Keq (equilibrium
coefficient for reversible reactions of NO3 and N2O5) and
correspondingly simulated [N2O5]/[NO2]×[NO3], especially under high-aerosol conditions in winter. This gap
reveals that the accuracy of Keq has a critical impact on the steady-state
analysis in polluted regions. In addition, the accuracy of γ (N2O5) derived by steady-state fit depends closely on the
reactivity of NO3 (kNO3) and N2O5(kN2O5). Based on a complete set of simulations, air mass of
kNO3 less than 0.01 s−1 with high aerosol and temperature higher
than 10 ∘C is suggested to be the best suited for steady-state
analysis of NO3–N2O5 chemistry. Instead of confirming the
validity of steady state by numerical modeling for every case, this work
directly provides appropriate concentration ranges for accurate steady-state
approximation, with implications for choosing suited methods to interpret
nighttime chemistry in high-aerosol air mass.
Improved monitoring of shipping NO2 with TROPOMI: decreasing NOx emissions in European seas during the COVID-19 pandemic
Authors: Riess Tobias Christoph Valentin Werner , Boersma Klaas Folkert , van Vliet Jasper , Peters Wouter , Sneep Maarten , Eskes Henk , van Geffen Jos
Published: March 2022

Abstract. TROPOMI (TROPOspheric Monitoring Instrument) measurements of tropospheric NO2 columns provide powerful information on emissions of air pollution by ships on open sea. This information is potentially useful for authorities to help determine the (non-)compliance of ships with increasingly stringent NOx emission regulations. We find that the information quality is improved further by recent upgrades in the TROPOMI cloud retrieval and an optimal data selection. We show that the superior spatial resolution of TROPOMI allows for the detection of several lanes of NO2 pollution ranging from the Aegean Sea near Greece to the Skagerrak in Scandinavia, which have not been detected with other satellite instruments before. Additionally, we demonstrate that under conditions of sun glint TROPOMI's vertical sensitivity to NO2 in the marine boundary layer increases by up to 60 %. The benefits of sun glint are most prominent under clear-sky situations when sea surface winds are low but slightly above zero (±2 m s−1). Beyond spatial resolution and sun glint, we examine for the first time the impact of the recently improved cloud algorithm on the TROPOMI NO2 retrieval quality, both over sea and over land. We find that the new FRESCO+ (Fast Retrieval Scheme for Clouds from the Oxygen A band) wide algorithm leads to 50 hPa lower cloud pressures, correcting a known high bias, and produces 1–4×1015 molec. cm−2 higher retrieved NO2 columns, thereby at least partially correcting for the previously reported low bias in the TROPOMI NO2 product. By training an artificial neural network on the four available periods with standard and FRESCO+ wide test retrievals, we develop a historic, consistent TROPOMI NO2 data set spanning the years 2019 and 2020. This improved data set shows stronger (35 %–75 %) and sharper (10 %–35 %) shipping NO2 signals compared to co-sampled measurements from OMI. We apply our improved data set to investigate the impact of the COVID-19 pandemic on ship NO2 pollution over European seas and find indications that NOx emissions from ships reduced by 10 %–20 % during the beginning of the COVID-19 pandemic in 2020. The reductions in ship NO2 pollution start in March–April 2020, in line with changes in shipping activity inferred from automatic identification system (AIS) data on ship location, speed, and engine.
VELOX – a new thermal infrared imager for airborne remote sensing of cloud and surface properties

Published: March 2022

Abstract. The new airborne thermal infrared (TIR) imager VELOX (Video airbornE Longwave Observations within siX channels) is introduced. VELOX is a commercially available TIR camera system that has been adapted extensively for atmospheric applications, which are introduced in this paper. The system covers six spectral bands with centre wavelengths between 7.7 and 12 µm. Currently, VELOX is installed on board the German High Altitude and Long Range Research Aircraft (HALO) to observe cloud and surface properties. It provides observations of two-dimensional (2D) fields of upward terrestrial spectral radiance with a horizontal resolution of approximately 10 m×10 m at a target distance of 10 km. Atmospheric temperature values are rather low compared to the originally intended commercial applications of VELOX and range close to the detection limit of the sensor. This challenge requires additional calibration efforts to enable atmospheric applications of VELOX. Therefore, required sophisticated calibration and correction procedures, including radiometric calibrations, non-uniformity corrections, bad-pixel replacements, and window corrections, are presented. Furthermore, first observations of cloud properties acquired by VELOX during the EUREC4A (ElUcidating the RolE of Cloud-Circulation Coupling in ClimAte) campaign are discussed, including an analysis of the cloud top brightness temperature, cloud mask/fraction, and cloud top altitude data. The data reveal the potential of VELOX to resolve the cloud top temperature with a resolution of better than 0.1 K, which translates into a resolution of approximately 40 m in cloud top altitude.
Effects of dimensionality on the performance of hydrodynamic models for stratified lakes and reservoirs
Authors: Ishikawa Mayra , Gonzalez Wendy , Golyjeswski Orides , Sales Gabriela , Rigotti J. Andreza , Bleninger Tobias , Mannich Michael , Lorke Andreas
Published: March 2022

Abstract. Numerical models are an important tool for simulating
temperature, hydrodynamics, and water quality in lakes and reservoirs.
Existing models differ in dimensionality by considering spatial variations
of simulated parameters (e.g., flow velocity and water temperature) in one
(1D), two (2D) or three (3D) spatial dimensions. The different approaches
are based on different levels of simplification in the description of
hydrodynamic processes and result in different demands on computational
power. The aim of this study is to compare three models with different
dimensionalities and to analyze differences between model results in relation
to model simplifications. We analyze simulations of thermal stratification,
flow velocity and substance transport by density currents in a medium-sized
drinking-water reservoir in the subtropical zone, using three widely used
open-source models: GLM (1D), CE-QUAL-W2 (2D) and Delft3D (3D). The models
were operated with identical initial and boundary conditions over a 1-year
period. Their performance was assessed by comparing model results with
measurements of temperature, flow velocity and turbulence. Our results show
that all models were capable of simulating the seasonal changes in water
temperature and stratification. Flow velocities, only available for the 2D
and 3D approaches, were more challenging to reproduce, but 3D simulations
showed closer agreement with observations. With increasing dimensionality,
the quality of the simulations also increased in terms of error, correlation
and variance. None of the models provided good agreement with observations
in terms of mixed layer depth, which also affects the spreading of inflowing
water as density currents and the results of water quality models that
build on outputs of the hydrodynamic models.
Towards physics-inspired data-driven weather forecasting: integrating data assimilation with a deep spatial-transformer-based U-NET in a case study with ERA5
Authors: Chattopadhyay Ashesh , Mustafa Mustafa , Hassanzadeh Pedram , Bach Eviatar , Kashinath Karthik
Published: March 2022

Abstract. There is growing interest in data-driven weather prediction (DDWP), e.g., using convolutional neural networks such as U-NET that are trained on data from models or reanalysis. Here, we propose three components, inspired by physics, to integrate with commonly used DDWP models in order to improve their forecast accuracy. These components are (1) a deep spatial transformer added to the latent space of U-NET to capture rotation and scaling transformation in the latent space for spatiotemporal data, (2) a data-assimilation (DA) algorithm to ingest noisy observations and improve the initial conditions for next forecasts, and (3) a multi-time-step algorithm, which combines forecasts from DDWP models with different time steps through DA, improving the accuracy of forecasts at short intervals. To show the benefit and feasibility of each component, we use geopotential height at 500 hPa (Z500) from ERA5 reanalysis and examine the short-term forecast accuracy of specific setups of the DDWP framework. Results show that the spatial-transformer-based U-NET (U-STN) clearly outperforms the U-NET, e.g., improving the forecast skill by 45 %. Using a sigma-point ensemble Kalman (SPEnKF) algorithm for DA and U-STN as the forward model, we show that stable, accurate DA cycles are achieved even with high observation noise. This DDWP+DA framework substantially benefits from large (O(1000)) ensembles that are inexpensively generated with the data-driven forward model in each DA cycle. The multi-time-step DDWP+DA framework also shows promise; for example, it reduces the average error by factors of 2–3. These results show the benefits and feasibility of these three components, which are flexible and can be used in a variety of DDWP setups. Furthermore, while here we focus on weather forecasting, the three components can be readily adopted for other parts of the Earth system, such as ocean and land, for which there is a rapid growth of data and need for forecast and assimilation.

Selain dapat diandalkan untuk membangun kekuatan maritim Indonesia, Kapal Pelat Datar ini juga memiliki daya saing kuat dan biaya produksinya jauh lebih murah jika dibandingkan dengan kapal-kapal berbahan baku kayu maupun fiber.  Kegiatan yang dilakukan oleh mitra usaha  salah satunya adalah pemotongan plat kapal dan di tempat usaha juga terdapat perahu dengan lambung datar sehungga mendorong kami untuk melakukan identifikasi plat kapal. Permasalahan lain yang dihadapi mitra adalah minimnya pengetahuan mengenai pengolahan besi scrap tersebut menjadi material sesuai pesanan yang diinginkan dari industry. Permasalahan lainya yang juga dihadapi adalah kurangnya pengetahuan mengenai identifikasi plat besi sehingga proses identifikasi tidak sesuai yang menyebabkan kesalahan dalam penafsiran harga.. Kegiatan Pengabdian  ini dilaksanakan di tempat usaha kecil limbah besi  di desa gedanganak Ungaran Timur. Pengolahan besi bekas  sangat potensial karena banyak  industri  baja  yang  menggunakan  bahan  skrap  sebagai  bahan  dasarnya,  baik  pada industri  mesin  maupun  industri  logam.  Besi bekasan  penggunaan  skrap  karena  bahan  ini  mudah didapat, memiliki nilai komparatif yang tinggi, memiliki komposisi kimia yang masih sangat memungkinkan  untuk  diolah  lebih  lanjut,  serta  dapat  mengurangi  permasalahan  yang berkaitan dengan limbah logam.

Adapun tujuan dari Penelitian ini adalah untuk Menganalisis Strategi Pengumpulan Zakat Profesi Pegawai Negeri Sipil di Badan Amil Zakat Kota Sukabumi. Penelitian ini disusun berdasarkan data lapangan yang menggunakan pendekatan kualitatif jenis deskriftif. Data yang dikumpulkan dengan menggunakan Observasi, wawancara mendalam, dan studi dokumentasi. Penelitian ini menemukan bahwa terdapat strategi yang digunakan BAZNAS dalam pengelolaan zakat profesi yaitu melalui sosialisasi. Melalui sosialisasi BAZNAS langsung terjun ke lapangan untuk mendatangi calon muzzaki yang di fokuskan pada PNS (Pegawai Negeri Sipil) melalui Instansi-instansi terkait. Sedangkan untuk pengumpulannya yaitu masyarakat datang langsung ke kantor BAZNAS atau juga bisa melalui transfer ke rekening BAZNAS. Pada penelitian ini juga menemukan kendal-kendala yang dihadapi BAZNAS dalam melakukan pengelolaan, terutama zakat profesi yaitu Para PNS beranggapan bahwa gaji PNS tidak memenuhi Nishob, tidak di hitung dengan tunjangannya. Setelah di gabung gaji pokok dengan tunjangan, maka PNS mencapai Nishob untuk membayar zakat profesi.

Given the importance of English for academic success and socio- economic mobility in Pakistan, proficiency in English as a Second language (ESL) is a necessity for Pakistani learners who aspire for better employability, social mobility, and academic success. However, despite the importance of comprehensible input in L2 for language learners’ progression, most Pakistani ESL learners have limited L2 exposure or opportunities to develop their L2 skills, particularly in their home networks wherein the use of Urdu or regional languages is favored. Adopting the theoretical lens of Milroy's social network theory (1987), this study investigates how Pakistani ESL learners’ social networks comprising family members, friends and peers promote or hinder their L2 learning. The data for the study was collected through questionnaires and interviews implemented with BS undergraduate ESL learners at a Pakistani university. This study finds that participants with weak and multiplex ties are more likely to make gains in L2 proficiency. In contrast, strong and uniplex ties hinders Pakistani ESL learners from improving their L2 proficiency as the learners tend to predominantly use Urdu or regional languages when communicating within such networks. Based on these findings, it is argued that social networks can be leveraged by ESL learners to gain exposure to English and opportunities for L2 learning.

This  paper  is  a  multidimensional  analysis  of  Pakistani,  Indian,  and  Bengali newspaper editorials, and they are also compared with British newspaper editorials. The purpose of the study is to explore lexico-grammatical patterns of change in English used in the countries separated by geopolitical divisions which remained parts of the British colony. A specialised corpus developed for this study consists of 288 text files of press editorials taken from May 2020 to May 2021 which were tagged using Biber’s tagger. Z score formula was used for the computation of dimensions score. Further, ANOVA was used to find the differences and similarities between the editorials from the selected countries. The data was also compared with British press  editorials.  The  results  indicate  that  Pakistani  press  editorials  are  the  most informational and abstract among all the countries. Indian press editorials are the most  non-narrative  and  the  least  abstract.  Bengali  press  editorials  are  the  most explicit and argumentative and the least informational. British press editorials are the least non-narrative, explicit, and argumentative among the selected countries. The results provide substantial evidence that the newspaper editorial registers of these  countries  are  not  only  different  from British press  editorials  but,  after  the partition  of  India,  each  country  has  developed  its  own  norms  of  producing discourse also.

Etiology of discharging MRM cavity is multifactorial. Knowing and addressing the etiological factors at the time of surgery is important to provide dry and safe ear to the patient. Objective: To evaluate the post-operative status of mastoid cavity after modified radical mastoidectomy.Material and Methods: This prospective Cross sectional study was conducted among 450 patients who came for open mastoidectomies in ENT Department, Saidu Group of Teaching Hospitals, Saidu Sharif Swat, Khyber Pakhtunkhwa, Pakistan. The study duration was from January 16, 2012 to December 09, 2019. Patients were postoperatively followed according to protocol and evaluated for residual cholestetoma and post mastoidectomy cavity status. The evaluation was conducted with endoscope and microscope. Data was obtained on pro-forma and SPSS 22 was used for analysis.Results: Out of 450 patients 109 (24.3%) were having recurrent persistent discharging mastoid cavities and 341 (75.7%) were having dry mastoid cavity. Multiple factors contributed to be the cause of discharging mastoid cavity with high facial ridge (89.9%) being the most common. More than one etiological factor in individual patients were also identified to be the cause for wet mastoid cavities.Conclusion: We concluded that complete exenteration of cholestetoma with lowered facial ridge, adequate meatoplasty and regular follow up is necessary to avoid post-operative mastoid cavity problems.Key words: Modified Radical Mastoidectomy, Mastoid Cavity, Cholestetoma.
