Published: March 2023

Saat ini teknologi barcode masih luas penggunaannya untuk mendata stok barang. Namun pada faktanya barcode juga memiliki kelemahan. Misal, barcode rentan mengalami kerusakan sehingga data di dalamnya sulit terbaca oleh scanner. Selain itu, barcode juga hanya bisa di-scan pada jarak tertentu, serta letaknya yang berbeda-beda di setiap produk juga membuat user harus mencari letak barcode terlebih dahulu sebelum di-scan. Teknologi RFID yang ditawarkan untuk menjadi jalan keluar dari permasalahan pada teknologi barcode juga memiliki beberapa hambatan untuk penerapannya, salah satu contohnya adalah biaya yang mahal. Pada penelitian ini dibuat sebuah sistem manajemen inventori berbasis website menggunakan HTML, CSS, dan PHP. Hasil black box testing fungsionalitas web menunjukkan hasil yang sangat baik, tingkat keberhasilannya mencapai 93,94%. Teknologi computer vision khususnya object recognition yang menggunakan arsitektur ResNet dalam CNN juga diterapkan untuk mengenali barang melalui input-an citra objek secara otomatis. Setelah melakukan training data terhadap sepuluh kelas yang sudah ditentukan, didapatkan sebuah model dengan validation loss sebesar 1.0834e-04 dan validation accuracy mencapai 100%. Berdasarkan testing yang dilakukan, model sudah mampu mengenali satu objek dalam satu frame foto dengan tingkat akurasi mencapai 90%. Namun akurasinya menurun untuk skenario testing dengan dua dan lima objek dalam satu foto, sehingga mendapatkan hasil tingkat akurasi 56% dan 54%.

Published: March 2023

Salah satu proses peningkatan mutu kopi adalah menyeleksi buah kopi yang matang dan belum matang pasca panen yang dilakukan dengan cara memilih satu per satu. Namun dengan cara tersebut terdapat kelemahan yaitu inkonsistennya hasil sortiran karena faktor subjektifitas dan intentitas cahaya. Sebagai solusi, pada penelitian ini didesain alat bantu dalam bentuk prototipe untuk menyortir buah kopi berdasarkan kematangannya. Kopi matang ditandai dengan warna merah, kopi setengah matang dengan warna kuning kemerahan dan kopi mentah dengan warna hijau. Kamera diletakkan dalam kotak guna mengurangi intentitas cahaya eksternal, digunakan untuk mengambil citra buah kopi kemudian citra buah kopi akan dipisahkan dengan background dengan metode segmentasi warna hue, saturation, value (HSV). Selanjutnya citra buah kopi diekstraksi untuk mendapatkan nilai setiap warna dengan parameter red, green, blue (RGB) dan HSV guna membentuk model klasifikasi metode support vector machine (SVM). Parameter SVM optimum yaitu cost (C)= 10,0 dan gamma (γ)= 0,001. Prototipe yang dibangun berbentuk persegi panjang dengan panjang 70 cm, lebar 10 cm dan tinggi 12 cm. Komponen penyortir yaitu servo yang memutar ke sudut 90o untuk klasifikasi “matang”, sudut 45o untuk klasifikasi “matang setengah” dan sudut 135o untuk klasifikasi “mentah” sedangkan conveyor belt digerakkan oleh motor DC 12 V. Meskipun pada proses prediksi perangkat lunak terdapat kesalahan prediksi namun perangkat keras telah bekerja dengan baik ditandai dengan servo berhasil memutar link ke sudut yang telah ditentukan sesuai hasil prediksi. Dengan demikian, dapat disimpulkan bahwa prototipe sistem penyortir buah kopi arabika berdasarkan kematangannya berhasil dibangun.

Published: March 2023

Purpose.Influence of preheating temperature and sodium silicate solute content in sand-sodium-silicate mixtures structured by SMS-process on their destruction work under knock loading action has been established. Methodology. Quartz sand brand 1K2O202, water, sodium silicate solute with specific gravity of 1.42…1.44 g/cm3 and silicate modulus of 2.8… 3.0 have been used in this work. Mixtures structuring has been realized in microwave furnace with frequency of 2.45 GHz and magnetron power of 0.9 kW. Samples heat treatment has been performed in laboratory resistance furnace in temperature range from 100 to 1100С with sample isothermal tempering at fixed temperature for 45...50 minutes. Samples knockout work has been calculated according to CNIITMASH method. Samples of structured by SMS-process mixtures destruction has been performed on laboratory impact machine brand 5033A. Samples structure has been examined on optical microscope at 100-times magnification. Results. With preheating temperature increasing sand-sodium-silicate mixtures structured in steam-microwave environment by SMS-method, containing from 0.5 to 2.5% sodium silicate solute with modulus of 2.8 ... 3.0, knockout work decreases exponentially. At preheating temperature from 800 to 1100°C it becomes practically zero. Mixtures, preheated to 600°C, knockout work does not exceed 20J. It follows that such rods or their individual parts can be removed from castings by shock-vibration method, even from copper and aluminum based alloys. Knockout the rods or their parts, in which after contact with poured into mold melt temperature did not exceed 600°C, has been recommended to carry out by castings immersing in water. Scientific originality. Mold and core mixtures structuring in steam-microwave environment solves the problem of sandsodium-silicate mixtures, containing sodium silicate solute up to 2.5%, knockout from castings for most foundry alloys used in industry. Practicalvalue. Investigation results will be useful for removal of sand-sodium-silicate rods and molds, structured by the SMS-process, technologies and equipment development.
Modeling of wear factor of locomotive wheel flange taking into
account the traction conditions
Authors: A Afanasov , S Holik , V Vasilyev , A Muntian
Published: March 2023

Since the advent of railways for nowadays the problem of wear of wheel flange isn’t completely solved. It is especially
relevant on the main railways.
In this paper the mathematical model is proposed for impact assessment of traction conditions on the wear of the flanges of locomotive wheels during the movement of the rail track. It was obtained on the basis of the kinematic scheme of
interaction of the wheel with the rail.
As a factor of wear was taken the work of friction forces per unit distance traveled. It is well known, the wear factor of
the flange is directly proportional to the relative sliding, which depends on the traction conditions and can be determined
by the value of the relative sliding surface of the guide wheel and the geometric parameters of the curve.
Thus the model that relates the wear factor to the parameters of the kinematic scheme of interaction of the wheel with
the rail and allows to take into account a traction conditions was obtained.
The proposed model allows to improve the modeling of the interaction of track and rolling stock as well as the design
process of devices that reduce the intensity of wear of the flanges and rails.

Analytical method of calculation of thermal fields of foundry cores
Authors: R Liutyi
Published: March 2023

The aim of the work is to create on the basis of the analysis of thermophysical parameters and regularities of
mathematical methods, which allows to calculate the distribution of thermal fields in molds and rods using a system of
analytical formulas.
The method of calculating thermal fields in foundry molds and rods developed and presented in this publication is based
on the finite difference method. Much attention is paid to the calculations of the dynamics of changes in the surface
temperatures of the casting rod and its center. The article shows that the basis for the correct calculation of the thermal
field of the rod is to establish the change in surface temperature in the first few seconds after the start of contact with the
melt. All currently available methods do not take into account this change in temperature.
A new concept is introduced - the period of thermal inertia of the rod. This is the period of time during which its surface
temperature rises from the initial value (ambient temperature) to a value corresponding to the surface temperature of the
casting. The period of thermal inertia depends exclusively on the thermophysical properties of the rod.
To calculate the temperature change in the center of the casting rod, a modified method of S. Schwartz was used:
instead of the constant contact temperature of the "casting-rod" in the formula takes into account the previously estab-
?ished dynamics of changes in this temperature.
The thermal fields of cylindrical foundry rods with diameters of 50 mm and 16 mm were calculated according to the
created mathematical method. A comparison of the results of calculations according to the developed method and with
the use of existing software is presented. The difference in design temperatures is 100 oC and more. The difference in
determining the thermal fields of a smaller diameter rod is particularly noticeable, which is due to the rapid dynamics of
changes in the surface temperature of the casting, which is currently not taken into account by current methods.
The developed mathematical technique can be offered as a theoretical basis for refining applied computer programs for
foundry production.

Published: March 2023

Background: The aim of this study is to evaluate the acute hemostatic effects of liquid and powder forms of AHA in severe bleeding model of rat renal vein. Materials and Methods: 10-12 weeks old, 24 male Wistar albino rats were randomly divided into three groups of eight animals each as the control, AHA liquid, AHA powder. The left renal artery and vein were revealed with a 3 cm vertical incision and the tip of the injector was used to puncture renal vein, causing bleeding. In all animals, regular gauze patch was pressed over the incised area for 10 seconds as soon as the bleeding began. Immediately after removing the sponge; physiological saline, AHA liquid and powder were applied with compress to injured site of relevant groups for 2 minutes, respectively. The time was recorded by chronometer and the area was checked after two minutes. Hemostasis that was not achieved after three applications was accepted as failure. Results: Cessation of the bleeding failed in all rats after three successive 2-minute physiological saline impregnated gauze applications in control group. Among AHA-treated groups, significant hemostasis efficacy was obtained from the liquid form than that of powder. Within first two minutes, bleeding in renal veins of five rats was controlled successfully in liquid group whereas powder group achieved hemostatic success in four rats. Conclusions: The vessel incision model in our study revealed fast-acting physical hemostatic properties of the liquid and powder formulations of AHA in the renal vein. This natural applicable product could be used to induce hemostasis in rat models of bleeding caused by various renal damages or trauma, and it could also prevent local bleeding in humans. More studies are needed to compare the efficacy of different formulations of the polysaccharide-based herbal product in various organs and surgical models.

Published: March 2023

Systemic vasculitis is a group of heterogeneous diseases characterized by inflammation of the vascular wall. They can be primary or arise in the context of another disease. Blood vessels of different sizes are affected, being mainly divided into small, medium and large vessels. Takayasu's arteritis is a vasculitis of the large blood vessels, most often affecting the aorta and its branches, subclavian arteries, iliac, femoral arteries and others. The presented clinical case concerns a woman with non-specific symptoms - low fever, sweating, weight loss, easy fatigue. After excluding an infectious genesis of the complaints, a diagnosis of Takayasu's Arteritis was made in the early phase of the disease as a result of Positron emission tomography. Corticosteroid and immunosuppressive therapy was started. When conducting a control PET, 20 months after the start of the therapy, a significant regression to  absence of the findings from the imaging study was observed.

Authors: Herdiansyah Haris , Dimyati Dindin
Published: March 2023

Children are affected by the Covid-19 pandemic, which has lasted nearly three years. The pandemic condition, which requires everyone to stay at home and interact at home, has a negative impact on the development of children's social interactions, particularly their socialization skills. It was discovered that there was a delay in the development of children's socialization due to hampered social learning processes, lack of direct social interaction, lack of social stimulation, and so on, causing children to grow up as individuals who were shy, inferior, and lacked social confidence, necessitating an intensive effort to accelerate their socialization skills so that children's mental development is not hampered, and they can re-adapt to their peers. The experimental design used was a two-sample pre-test-post-test design, with all respondents divided into experimental and control groups. Purposive sampling was used in this study. A socialization skills questionnaire was used as the research instrument. Pearson's alpha was used for validity tests, and Cronbach's alpha was used for reliability tests. Multiple regression was used in hypothesis testing. The data analysis revealed that the difference between pre-test and post-test scores had a t-value of 5.079 and a probability value (sig. 2-tailed) of 0.000 (P0.01) . This finding indicates a difference in socialization skills between KE and KK.
Proposal of compressed sensing-assisted Brillouin optical correlation-domain reflectometry for effective repetition rate enhancement
Authors: Yao Yuguo , Lu Yuangang , Mizuno Yosuke
Published: March 2023

Compressed sensing (CS) is proposed in Brillouin optical correlation-domain reflectometry to enhance the effective repetition rate at any single position along an optical fiber. Through the random selection of modulation frequencies applied to the laser source in each epoch that the entire fiber is traversed and the reconstruction of the under-sampled data, a picture of the distributed and time-varying Brillouin frequency shift values can be achieved. Dynamic strains at frequencies of 20 Hz and 40 Hz are measured with CS at different under-sampling rates. The effective repetition rate is enhanced by 10 times with an improved temporal resolution.

Furthermore, a zero-field splitting parameter E which reflects crystal distortion after irradiation significantly reduces for irradiation above 650 °C. These findings indicate that thermal treatment is an effective method for a V

Trends in Environmental Valuation: The Challenge to Nigerian Geography and Sustainable Development
Authors: Chokor B. A.
Published: March 2023

Environmental valuation, which is interdisciplinary in scope and practice, has a considerable role in natural resource management. This paper contends that assessment studies required to prioritize and preserve the ecological integrity of Nigeria’s varied environments have been limited in geography and argues the need to realign with newer perspectives. The review problematizes the relative value of the seemingly more robust, precise but conventional quantitative tools of assessment widely deployed in the discipline and the efficacy of the experiential perspectives espoused by humanistic geographers, whose impetus comes from conceptual borrowings. The propriety of these borrowings is evaluated. The paper then suggests that while the increasing interest in valuation has largely been spurred by the need to establish criteria for minimizing and managing the impact of human activities on the environment, the validity of much of the methodologies adopted has been far from clear, although a notable contribution in Nigerian geography is the attempt at reducing a composite or aggregate index of environmental quality. While this approach has benefits for environmental planning and design, the paper also outlines new directions for more impactful research, especially against the backdrop of the upsurge of interest in environmental or resource economics.
Determinants of Mobile Telephone Usage for Healthcare Service Utilization
Authors: Aiyegbajeje Femi Ola , Ajayi Dickson ’Dare
Published: March 2023

Mobile telephone technology has penetrated all areas of life, and developing nations are enjoying the benefits it brings to various sectors, particularly healthcare. Existing literature have shown various determinants of mobile telephone usage for different purposes. However, very little attention has been given to the factors that determine the use of mobile phone for healthcare service utilization. This is crucial to healthcare service delivery planning processes. This paper, therefore, examines the factors influencing mobile phone use for healthcare services in Lagos. Using a structured questionnaire, information on demographic profile of patients, mobile telephone ownership and usage, and the determinants of use of a mobile phone for medical purposes was obtained from seven-hundred and eleven out-patients in Lagos University Teaching Hospital (LUTH) and Lagos State University Teaching Hospital (LASUTH). The independent and joint contribution of determining factors was analyzed using logistic regression model. The result shows that patient’s travel-time to the hospital is the major determinant of mobile phone usage for medical service utilization (Odd Ratio: 3.257). This implies that the long hours spent on travelling by patients to the healthcare centre due to heavy traffic congestion in Lagos metropolis may have encouraged the use of mobile telephone for healthcare utilization purposes. The paper suggests that healthcare policymakers should make a concerted effort to effectively manage the chaotic traffic congestion and encourage the use of mobile phones as one of the methods for providing medical services in Lagos metropolis.

Published: March 2023

One of the assumptions of the Theory of Planned Behaviour (TPB) is that external factors (subjective norms) may shape individual behavioural intentions. Based on this assumption, this study was carried out to find if perceived social support and social media addiction predict tendency to engage in examination misconduct. One hundred and eighty (180) participants comprising 112 females and 62 males, aged between 18-40 years with a mean age of 22.77 years and standard deviation of 3.61 were involved in the study. These participants were undergraduates from Nnamdi Azikiwe University, Awka. Three instruments were used in the study. They include: Examination Malpractice Questionnaire (EMQ), Multidimensional Scale of Perceived Social Support (MSPSS), and Social Media Addiction Scale (SMAS). Two investigations were made in the study using hierarchical multiple regression analysis. The first investigation led to the findings that social support (family, friends and significant others) jointly predicted tendency to engage in examination misconduct positively and significantly, ß (3, 175) = .107**. The first findings revealed also that friends’ social support predicted tendency to engage in examination misconduct negatively and significantly, ß = -.253* while significant others’ social support predicted tendency to engage in examination misconduct positively and significantly, ß = .416**. It was also revealed that family social support predicted tendency to engage in examination misconduct negatively but not significantly, ß = -.047. The second investigation led to the findings that social media addiction significantly predicted tendency to engage in examination misconduct, ß (1, 174) = .048*. This indicated that social support and social media addiction predicted tendency to engage in examination misconduct. The findings may have implications for planning, understanding and designing programs for prevention of examination malpractice. It was recommended that school management should institute workshops and symposium each semester on perceived social support and social media addiction with respect to examination misconduct.

Authors: Abdullahi Haruna Ishola , Oyinlola Adedoyin O.
Published: March 2023

The social media brought crises like divorce and violence into the family unit. Hence, this paper assessed social media and marital instability as an amalgamation for domestic violence in Ota Ogun State, Nigeria. The study anchors on betrayal theory and modernisation theory. The study was cross-sectional survey and descriptive in nature hence, its method of data collection and analysis was both quantitative and qualitative. The primary data was obtained through administration of 150 questionnaires to the residents of Ota through convenience and purposive sampling methods. Content analysis of textbooks, journals and online resources were the sources of secondary data. Out of the 150 questionnaires taken to field only 137 were returned, consequently the response rate was 91.33%. Findings showed that 61% of the respondents were male, 39% were female, 95 of the respondents had internet-enabled android phones and 5% of the respondents did not have android phones. The results of the hypothesis tested showed that the Spearman Regression analysis has a value of 0.94 which was greater than P value of 0.05 at 5% level of significance, hence, the null hypothesis was rejected. This study recommends adequate orientation on the use of social media and subsistence counselling among couples. This study will be valuable to the community, families and researchers in the field of sociology of family and crime.

In this study, the relationship between family relationship and dual-earners as correlates of marital satisfaction was examined among married couples. The participants were 394 married couples who volunteered from one randomly selected church in Awka South Local Government Area of Anambra state. They are comprised of 130 males (32.9%) and 264 females (67%) with a mean age 43.94 years and standard deviation of 9.11 years. Two instruments were deployed for data collection; Index of Family Relation (IFR) by Hudson (1982) and Index of Marital Satisfaction (IMS) by Hudson (1982). Dual-earnership information was derived from the demographic section. The correlation design was adopted; and data analysis was done using Pearson Product Moment Correlation. Result of Zero Order Correlation Coefficient revealed that family relationship correlated positively and significantly with marital satisfaction r = .36, p <.01, while the association between dual-earners and marital satisfaction was negative r = -.02, P < .05. Therefore, hypothesis one was confirmed. It was concluded that family-relationship is a positive construct that enhances marital satisfaction. It was recommended that married couples should enrich their family relationship in order to achieve a more satisfactory marriage.
A differential p-ISFET based on-chip pH sensor with substrate based drift reset capability
Authors: Prathap Vaishak
Published: March 2023

This paper presents a monolithic, inexpensive, label free, robust pH sensor that can be fabricated in an unmodified CMOS process. The sensor uses a differential p-ISFET architecture which substantially reduces non-ideal common mode effects which corrupt readout in ISFET based pH sensors and occupy only a small footprint. Additionally, the design offers the capability to correct for drift through control of the n-well voltage, which has not been demonstrated previously. We present results obtained from testing the sensor that is fabricated in the AMS 0.35μm process, including a demonstration of the drift correction. We demonstrate a differential sensitivity of 15 mV/pH over the entire pH range, with the ability to remove the already small drift of 0.1 mV/min using the bulk-source voltage adjustment.

Published: March 2023

The relative influences of the reorganization energies of the classical and quantum modes on the maximum position of the rate constant – reaction free energy curve have been studied. In the framework of the continuum electrostatics, the electron transfer reorganization energies in methyltetrahydrofurane solutions for the system biphenylyl – spacer – acceptor were calculated. For different acceptors the solvent reorganization energy varies from 1.0 to 1.1 eV. When added with the rather small reorganization energies for classical intra-molecular modes we obtain 1.13 - 1.34 eV. With account of possible errors this coincides practically with the experimental estimate of the energy at the maximum of the rate–free energy curve DGmax ? -1.2 eV. Hence, we can conclude that the reorganization of quantum modes does not influence substantially the position of this maximum. To the contrary, in a non-polar solvent isooctane were the solvent reorganization does not play any role the reorganization of the quantum intra-reactants modes becomes determinant. These conclusions agree fully with the results of the general theoretical analysis and should be accounted for in the experimental data interpretation.

Published: March 2023

Background: Bladder cancer is one of the most common human cancers in Iraq and the world. While smoking, age sex, and occupational exposure to aromatic amines are the most prominent among the risk factors identified, long term Inflammation and chronic infection may largely play some role in urinary bladder cancer (UBC) development. In the present study we worked on urinary bladder cancer and noncancerous Formalin-Fixed Paraffin Embedded (FFPE) Tissue specimens of Iraqi patients, the current study used Acid Fast Stain and Transmission Electron Microscope for detection of Mycobacterium tuberculosis in Urinary Bladder tissues.
Objectives: microscopical detection of Mycobacterium tuberculosis in urinary bladder cancer.
Methodology: The current study used urinary bladder cancer (UBC) formalin-fixed paraffin embedded tissues (FFPET) specimens of Iraqi patients collected of several privet histopathology labs in AL-Najaf province, the specimens were 50 specimens of UBC patients and 25 different noncancerous pathological bladder specimens. Slides of urinary bladder FFPE tissues were stained with Ziehl-Neelsen (ZN) stain. Examining of slides were conducted using Transmission Electron Microscope (TEM) imaging was performed special procedure was used for TEM slides preparation.
Results: FFPE tissues were stained with Ziehl-Neelsen (ZN) stain. Examining of slides showed presence of high number of acid fast bacilli (AFB) in one microscopical field. UBC tissue slides showed the highest percentage comparing to noncancerous patients (76.6% and 23.4%) respectively. For further confirmation and study of ZN stain results, Transmission Electron Microscope (TEM) imaging was performed. The results showed presence ofdifferent morphological shapes of acid fast bacilli cells appeared in TEM fields and most cells were observed attaching to the urothelial cell membrane.
Conclusions: high percentage of MTBC and MTB were detected among patients with UBC compared to noncancerous cases.
Recommendations: modern techniques should be used for MTBC and MTB detection in laboratories, and further study for the relationship between chronic MTB infection and UBC are required.

Results: The findings of the study indicate that most of the samples (34%) have both sever, moderate anxiety level and (32%) of the samples have mild anxiety level. There is highly significant relation in anxiety level with sociodemographic data (age, education level, loss of parents), there was significant relation in anxiety level with sociodemographic data (age at admission, financial support).The findings of the study indicate that most (48%) of the samples have mild depression, (30%) of the samples have severe depression level and (22%) have moderate depression level. There is highly significant relation in depression level with sociodemographic data (age, loss of parents), there was significant relation in anxiety level with sociodemographic data (education level).
Conclusion: All orphans affected with the psychological problems in different levels and there are weak relationship between females and males in gender group with psychological problems.
Recommendation: The study recommends that give an educational program to those who were responsible about the orphanage to increase their knowledge toward the psychological problems such as (anxiety, depression). A guidance towards religious and moral education specialist to reduce the conflict between the orphans and development of psychosocial problems.
