Traffic management is a major problem in large cities of Pakistan. Pakistan is a developing country with aging infrastructure of roadways and railways. The traffic conditions are deteriorating due to inappropriate design. Traffic problems due to improper design have resulted in loss of the life and property. The main purpose of this study is to identify the existing traffic condition of Sialkot City, Pakistan at Daska, Model Town Bhed Puli and Gulistan Cinema intersection. The Sialkot City is connected with Narowal, Gujrat and Gujranwala through Metalled streets. Sixteen hours of Manual Traffic Count was conducted at each intersection. Equivalent factors for Passenger Car Unit recommended by Government of Punjab are used. Afterwards, analysis has been carried out using Signalized and unsignalized Intersection Design and Research Aid (SIDRA) software. It is observed that Level of Service (LOS) is poor and Volume Capacity Ratio (V/C) is higher for the selected intersections. In order to eliminate the issues of the selected intersection, a few enhancements are suggested and are described in detail. LOS is improved by provision of signals for Gulistan Cinema intersection and Model Town Bhed Puli intersection along with separation of slow moving vehicles by providing service lane; whereas for Daska intersection, freeway provided for traffic channelization with provision of bus bay and parking lane.

Introduction/Objective. Primary open-angle glaucoma (POAG) treatment should be individually tailored to the disease severity and type, effectiveness and secondary side effects of the medications used. This research aimed to assess the direct medical costs and the cost effectiveness associated with pharmacotherapy in visually impaired people with POAG according to disease severity. Methods. This scientific study is designed as an observational cross-sectional study with a quantitative analytical approach and was conducted in the period from July 2020 to June 2021 on the territory of North Macedonia. The study included 157 patients with binocular POAG in the early, moderate and advanced clinical stage, up to the age of 67, with changes in visual acuity and work ability. During the assessment of the effects of pharmacotherapy were analyzed the types, mutual correlations and effectiveness of the most commonly prescribed antiglaucomatous medications and the cost benefit from their administration. Direct medical costs are calculated according to disease severity in the last 12 months using real-time data of public interest. Results. The beta blockers due to their affordable price and availability are the dominant option with high-cost benefit for primary treatment of POAG. Antiglaucoma medications and diagnostic procedures are major components of direct medical treatment costs. Conclusion. Pharmacotherapy is the dominant alternative compared to other types of treatment because it is safer and is associated with greater effectiveness and lower direct medical costs.

Objective: Trans-fatty
acids (TFAs) have harmful biologic effects that could increase risk of type 2
diabetes (T2D), but evidence remains uncertain. We aimed to investigate the
prospective associations of TFAs biomarkers and T2D by conducting an individual
participant-level pooled analysis.

Research design and methods: We included data from an
international consortium of 12 prospective cohorts and nested case-control
studies from six nations. TFA biomarkers were measured in blood collected
between 1990-2008 from 25,126 participants aged ≥18 years without prevalent
diabetes. Each cohort conducted de novo harmonized analyses using a
pre-specified protocol, and findings were pooled using inverse-variance
weighted meta-analysis. Heterogeneity was explored by prespecified between-study
and within-study characteristics.

Results:
During mean follow-up of 13.5 years, 2,843 cases of incident T2D were identified. In
multivariable-adjusted pooled analyses, no significant associations with T2D were
identified for trans/trans-18:2, RR, 95%CI: 1.09 (0.94-1.25), cis/trans-18:2, 0.89 (0.73-1.07), and trans/cis-18:2, 0.87 (0.73-1.03). Trans-16:1n-9,
total trans-18:1, and total trans-18:2 were inversely associated
with T2D (RR, 95%CI: 0.81, 0.67-0.99; 0.86, 0.75-0.99; and 0.84, 0.74-0.96, respectively). Findings were not
significantly different according to pre-specified sources of potential
heterogeneity (each P ≥0.1).

Conclusion: Circulating
individual trans-18:2 TFA biomarkers were
not associated with risk of T2D, while trans-16:1n-9,
total trans-18:1, and total trans-18:2 were inversely associated. Findings
may reflect the influence of mixed TFA sources (industrial vs. natural ruminant),
a general decline in TFA exposure due to policy changes during this period, or
the relatively limited range of TFA levels.

The paper presents research of brittleness cement blends with siliceous additives using impact strength. The advantages of the developed method are simplicity of definition, low cost of equipment and operation. In the presented research were studied additives on the basis of finely ground glass obtained from waste glass containers and pozzolanic additives as fly ash, silica fume and synthetic silica. Increase in additives amount in respect to the cement mass reduces brittleness by ~10 % after 28 days of curing. The addition of 35 % of ground glass decreases the brittleness of the cement paste, whereas 10 % of pozzolanic additive increase it during the period from 1 to 28 days. Determination of brittleness using impact strength can be used to evaluate the activity of siliceous additives in cement blends.

Obstacles to Job Satisfaction Among Workers Living with War Caused Disabilities in ‎Changara District in Mozambique. ‎
Authors: Nyanga Takupiwa M.
Published: February 2022

Job satisfaction of all categories of workers is one of the key antecedents that ensure increased competiveness of organizations. The need to establish factors that impede job satisfaction among people living with war induced disabilities was the main aim of this study. Furthermore, effects of war that adversely affect the attitude of workers with war induced disabilities towards their work were a major driver of this paper. The study employed a pure qualitative research approach where data was collected using face to face interview from 29 participants and analyzed using the thematic data analysis method. Participants were selected using snowballing sampling technique. Job satisfaction was found to be extremely low among employees living with war induced disabilities. People with different disabilities experience a host of work and home related challenges which significantly affect their job satisfaction levels. The problems encountered by people living with disabilities that affect their job satisfaction are mainly centered on ergonomics, lack of relevant assistive technology, stigmatization, discrimination and lack of physical and emotional protection from weather conditions, workmates and supervisors. The link between job satisfaction of workers with war induced disabilities and organizational competitiveness would further advance theory of job satisfaction and provide managerial implications that is helpful for an improved organizational performance. The study recommended that organizations should re-organize their work stations so as to accommodate the needs of people with disability.

Relevance of al-ṡaman al-‘adl on Modern Transaction
Authors: Sahir Wahida
Published: February 2022

A perfectly competitive market can produce fair prices for sellers and buyers. If the market mechanism is disrupted, fair prices will not be reached. This study aims to determine the economic thought of Islamic Middle Ages (Al-Ghazali, Ibn Taymiyah and Ibn Khaldun), analyze the concept of demand and supply prices and the contribution of al-aman al-'adl in demand and supply prices according to Al-Ghazali, Ibn Taimiyah and Ibn Khaldun (Middle Ages). This research uses the method of library research with a historical, sociological and economic approach. Data sources used are primary data and secondary data.The results of this study indicate that Al-Ghazali was one of the thinkers of Islamic economics who initiated the concept of al-aman al-‘adl with a socialist style of thought. Ibn Taymiyyah was a cleric with a socialist mindset that was specifically focused on the market mechanism, emphasizing his views on the free market. Ibn Khaldun was the pioneer of the birth of sociology which summarized the discussion of history-philosophy and political economy. The style of Ibn Khaldun's economic thought is more directed to the style of socialist thought which strongly emphasizes the importance of a free market system. The concept of demand analysis is that the higher the price, the lower the demand will be. Meanwhile, the concept of supply analysis is the higher the price, the more number of goods offered. Al-ṡaman al-‘adl's contribution (fair price) according to Al-Ghazali addresses the issue of price and profit simultaneously without distinguishing between costs and income. The contribution of al-ṡaman al-‘adl (fair price) according to Ibn Taymiyyah maintains fairness in conducting reciprocal transactions and other relationships among members of the community, the concept of a fair price only occurs in competitive markets. The contribution of al-ṡaman al-‘adl (fair price) according to Ibn Khaldun is the price is very much determined by the demand and supply

Ultrasound Shear Modulus and Thickness of Lateral Abdominal Muscles in Different Contractile States in Relation to Self‐ Reported Hip/Groin Problems in Youth Soccer Players
Authors: Linek Pawel , Booysen Nadine , Stokes Maria
Published: February 2022

To date, no studies have assessed lateral abdominal muscles’ (LAM) elasticity and thickness in relation to hip and groin symptoms in any population. The objectives were to a) assess the relationship between LAM ultrasound measurements (elasticity and thickness) and self-reported subscales of the Copenhagen Hip and Groin Outcome Score (HAGOS) and b) compare LAM elasticity and thickness between asymptomatic and symptomatic sides. Shear modulus and thickness of the oblique external (OE), internal (OI) and transversus abdominis (TrA) muscles in 25 young soccer players were assessed at rest and during isometric contraction using ultrasound shear wave elastography. HAGOS subscales were used to assess self-reported hip/groin problems. There was a significant (p < 0.05) moderate correlation between allometric-scaled OI resting thickness (mean of right and left) and the Activities of Daily Living (r = 0.40), Sport (r = 0.57) and Quality of Life (QOL) (r = 0.41) HAGOS subscales. Also, a moderate significant correlation was found between allometric-scaled TrA resting thickness and the QOL subscale (r = 0.47). Moderate correlations were found between resting OI shear modulus and the QOL (r = 0.44), between right TrA shear modulus during contraction and Symptoms (r = 0.57), and between the left TrA shear modulus during contraction and Physical Activity (r = 0.41) subscales. No differences were found between the symptomatic and asymptomatic side in thickness and elasticity measurements among soccer players with unilateral symptoms (p > 0.05). The relationships found between LAM and hip/groin problems in youth male soccer players indicate that muscles are thinner and more elastic (less stiff) in more symptomatic athletes.

Published: February 2022

The purpose of the study was to evaluate the impact of (1) maximal muscular strength of the upper body and (2) fat mass on musculoskeletal pain and sagittal spinal curvature deviations in elite Polish sitting volleyball players. The study examined twelve players (age = 35.4 ± 6.9 years). The assessments were performed based on objective (anthropometric examinations, Medi Mouse, 1RM test) and subjective (NMQ = 7) measurements. All statistical analyses were performed using the SPSS. The lower back, the upper back and the neck were the most frequent painful areas. Statistical analyses showed a significant relationship between lumbar lordosis (LL) sagittal standing extension (r = 0.62; p = 0.03) and thoracic kyphosis (TK) sagittal standing flexion (r = -0.63; p = 0.28) with the 1RM. Furthermore, correlations between a body adiposity index and TK sagittal standing flexion and extension (r = -0.65; p = 0.05, r = - 0.58; p = 0.0.05) as well as LL sagittal standing flexion (r = 0.61; p = 0.05) were found. The body mass index correlated with wrist pain, whereas a very high relationship was found between pain in the wrists and knee joints. Neck pain positively correlated with TK and LL sagittal standing. Low back pain correlated with LL sagittal standing flexion and TK sagittal standing extension. Fat mass impacts the depth of anteroposterior spinal curvatures, what may cause pain in the neck and the lower back. The 1 RM bench press may influence the prevalence and location of musculoskeletal pain, whereas its values might be predicted by the depth of TK. A lower 1RM in the bench press may impact sagittal spinal curvature deviations. Deepen TK and LL significantly contribute to the prevalence of the neck pain.

From what in March 2020 seemed as a simple health issue, the Covid-19 pandemic has led to a global crisis with
a huge social, economic and educational impact. As a result, many countries that were not prepared for such a
situation, in terms of infrastructure, had to abruptly adapt with the resources they had to their disposal at that
time. For example, in Romania, most schools and universities moved their classes online via different online
platforms, but students from rural areas were not able to attend school at all. The present study aims to evaluate
students’ perceptions and difficulties regarding online (blended) learning compared to traditional classroom
attendance with a main focus on the difficulties encountered in the process of learning economic subjects. We
performed a quantitative research by implementing an online questionnaire which was sent out by the end of the
second semester of 2020 – 2021 school year. The respondents were freshmen from The Bucharest University of
Economic Studies, The Faculty of Business and Tourism, enrolled in October 2020. Being aware that the quality
of their learning might be affected via blended learning, all these respondents agreed to take part into various
optional activities provided by the means of the Secondary Education Project – ROSE BT. Therefore, the current
study might offer an useful insight into difficulties encountered by these students and solutions provided by both
teachers and the university as an institution interested into facilitating the online education process. Moreover,
the results will show possible factors that may determine difficulties into understanding various economic subjects
and students’ own motion for improving their situation.
TOWARD CONCEPTUALIZATION OF AN EMERGENT FORM:
EXOTOURISM
Authors: Neacșu Marius-Cristian
Published: February 2022

This study represents an exploratory research, which aims to create an incipient theoretical framework for
conceptualizing a new notion, namely that of exotourism. The new cosmic competition, which is different from the
one during the Cold War, through its commercial and private character, generated a phenomenology associated
with a new form of tourism, respectively trips for recreational purposes in the space, with private character, for
which we propose the term ‘exotourism’. Thus, as objectives of this exploratory research we mention: testing a
working definition, critical analysis of terminology and identifying the essential characteristics of exotourism,
which would give scientific legitimacy to exotourism, as well as the emerging concept.

Published: February 2022

Najčešće korišćen izvor za dobavljanje podataka o poljoprivrednim granicama je katastar. Međutim, proces ekstrakcije katastarskih podataka je i dalje značajno manuelan proces, što neizbežno dovodi do povećane verovatnoće za grešku u merenju, kao i pove­ćanih troškova. Jedan od mogućih načina prevazilaženja spomenutih problema je automatizacija procesa delineacije granica parcela korišćenjem satelitskih slika i metoda dubokog učenja. U ovom radu predstavljena je konvolu­tivna neuronska mreža za detekciju (tj. delineaciju) poljoprivrednih granica, gde se kao ulaz modela koriste multi-spektralne satelitske slike. Istrenirani model uspešno prepoznaje granice poljoprivrednih parcela i ostvaruje rezultate bolje od autora originalnog skupa podataka. Iako su ostvareni zadovoljavajući rezultati, predloženi su koraci za poboljšanje predloženog rešenja koji bi mogli dovesti do ostvarivanja robusnijih rezultata.

Certification and delivery tests of steels for important structures and welds include determination of static fracture toughness parameters on notched samples with a fatigue crack grown in advance from the notch tip. Regulatory documents governing these tests contain certain requirements to this crack’s front shape. This paper discusses the techniques that made it possible to overcome the challenges in crack growth, as well as presents experimental confirmation of their efficiency.

High-strength steels (yield point 500 MPa and above) have long been used in deepwater technology. Nowadays they are becoming increasingly popular in shipbuilding and offshore engineering for certain highly-loaded structural members. Stronger steel means higher absolute stresses in structure, so it becomes necessary to analytically estimate fatigue strength, not only high-cycle, but low-cycle, too, where fatigue crack growth stage comprises a considerable share of service life. Presently, literature offers only scarce data on fatigue cracking toughness of these steels because until quite recently these materials were required only for certain specific applications. Meanwhile, this kind of materials features a number of peculiarities mostly related to the effect of corrosive environment upon their behavior: specifically, hydrogen embrittlement that might be caused only by static tension load but by cyclic loading as well. This paper presents the experimental data on how high-strength steel proneness to hydrogen embrittlement (the main mechanism of corrosive cracking under stress) affects fatigue crack growth rate in corrosive environment. The studies were performed on the specimens of Cr-Ni-Mo-Va steel alloy (rated yield point at least 780 MPa). It is shown that steels with greater susceptibility to corrosive cracking under stress feature 2–2,5 higher growth rate in corrosive environment. In extreme cases, fatigue crack toughness curves not taking into account potential susceptibility of material to hydrogen embrittlement and actual loading rate might lead to considerably overstated strength estimates. The study also yielded limit coefficients for fatigue cracking toughness curves that enable sufficiently conservative assessments.

The purpose of this work is to describe and summarize main design principles of sealing joints for cable penetrators of deepwater vehicles. The study was performed on typical sealed areas of watertight cable penetrators, like soldered joint between copper sheath of a heat resistant cable with mineral isolation (KMZh) and cable penetrator body; polymeric termination of cable ends; sealing joint of metal penetrator body in pressure hull with circular elastomeric gaskets. The case study in this paper is a metal casing attached to KMZh cable by a heat-resistant silverized brazing alloy. The quality of soldering joints was estimated metallographically, i.e. by means of optical microscopy and electronic raster spectroscopy. Watertightness of KMZh cable is ensured by reactoplast-based polymers that must be not only adequate to their operational conditions but also comply with fire safety regulations for ships. Watertightness of penetrator interface with pressure hull is achieved by means of elastomeric gaskets. The study investigated main sealing joints of penetrators, as well as the mechanisms achieving watertightness of each given joint. Analysis in ANSYS software package yielded the optimal thermal scenario of casing warm-up offering the best quality of both soldering process and adhesion to the KMZh cable. The calculation was also performed for the minimum length of brazed joint of constant width so as to ensure strength and watertightness at different external pressures. Calculation results were performed by hydraulic tests of penetrator samples. The study also identified the peculiarities of polymeric sealant selection. A promising approach for cable termination manufacturing would be to use heat-resistant materials featuring shape memory effect.

Published: February 2022

This paper describes the study intended to work out functionality requirements of a digital assistant software for Arctic offshore drilling platforms. The study followed the method of logical analysis. The criteria used to formulate key requirements to the software functionality were based on the interview with competent experts working at marine drilling platforms and chosen as per their respective work experience in offshore drilling. Arctic developments have become especially relevant in the last years because oil and gas reserves of the Eastern Siberia and mainland fields in the Russian North are depleting, so it becomes necessary to go for offshore oil and gas in the Arctic. The progress in digital technologies is one of the ways to make Arctic oil & gas production more efficient and safe, which is especially relevant taking into account its harsh environments. Development and induction of personalized tools could improve both occupational and personal discipline of the staff manning offshore platforms, as well as optimize working hours and mitigate industrial injuries.

This work mainly aimed to identify the most suitable calculation approaches and methods for the effect of inputs upon the outputs of a functionally-mathematical library with inaccessible source code, and further use these methods and approaches to develop an input ranking tool. These methods and approaches were studied using a generalized regressive model representing an arbitrary functionally-mathematical library (an executable module). The paper studied two approaches to the determination of input effects upon the outputs: 1) correlation analysis; 2) neural network method. The first method is analytical calculation (couple by couple) of Pierson correlation coefficients for all input and output parameters. As an alternative, the study also investigated rank-based Spierman and Kendall correlations. The second approach basically meant neural network learning with required accuracy using the variation set of executable module inputs and their respective outputs with subsequent calculation of contribution from each parameter to the overall result for the neural network after learning. These approaches have also been compared in terms of several major criteria, i.e. application peculiarities, speed and output quality. The analysis has shown that neural-network learning method, despite its certain drawbacks, is more suitable for the task of this study. The paper also outlined possible ways for further improvement of this method and complexity increase of the suggested functionally-mathematical library model.
