An Automatic System to Detect Presence of Water in Supply Lines and Maintain Water level of Underground and Overhead Tanks
Authors: Ali Murtaza , Ali Munsif , Dal Mushtaq , Rana Iqra , Qureshi Arsal Mehmood
Published: March 2021

Commonly most of the houses rely upon the overhead and underground tanks as the main source of water. People usually turn on the motor when their taps go dry and switch off the motor when the tank starts overflowing. This results in needless wasting of water and the lack of water in emergencies. This water is mostly coming through supply line pipes installed by the government through different schemes. The timing of this water coming is mostly irregular because it varies time to time, and in areas where it is fixed, the time is inconvenient for domestic residents to switch ON their motors and fill their tanks. Either the water comes late at night or in the daytime when the people are mostly at their jobs, so they are unable to turn ON their motors. This paper presents a solution to both these problems, a hardware model has been developed using Arduino as the main microcontroller, ultrasonic sensors to detect the level of water in tanks two pumping motors one for underground and one for an overhead tank. And one a water flow sensor is used to automatically detect the water coming in supply lines and switch on the motor. The proposed system saves water, electrical power and human efforts as the whole system is automatic.

Çalışanların örgüt içerisinde yarattığı yenilik bir örgüt için çok büyük değer ifade etmektedir. Bu değeri büyütebilmek ve çalışanların yenilikçi iş yapma davranışında bulunma motivasyonunu artırmak büyük ölçüde bir liderin liderlik yapma tarzına bağlıdır. Bu nedenle yenilikçilik iklimi ve bu iklimin sebep olduğu yenilikçi iş yapma davranışı liderlik tarzından ayrı düşünülemez. Birbiriyle bu denli alakalı olan bu kavramlar arasındaki ilişkileri daha iyi anlayabilmek ve bu ilişkileri daha net bir şekilde ortaya çıkarabilmek amacıyla yapılan bu çalışmada, liderlik tarzının yenilikçilik iklimine, yenilikçilik ikliminin ise yenilikçi iş yapma davranışı üzerine olan etkisi incelenmeye çalışılmıştır. Bu varsayımları test etmek amacıyla Mersin ilinde lojistik alanında faaliyet gösteren 19 forwarder firmasında çalışan 114 beyaz yakalı personelden elektronik ortamda yapılan anket yöntemi ile veri elde edilmiştir. Tam sayım yöntemiyle elde edilen bu veriler SPSS ve AMOS paket programları kullanılarak değerlendirilmiştir. Analiz sonucunda liderlik tarzı ile yenilikçilik iklimi arasında pozitif yönde ve orta düzeyde; yenilikçilik iklimi ile yenilik yapma davranışı arasında ise yine pozitif yönde ancak yüksek düzeyde anlamlı bir ilişki olduğu tespit edilmiştir. Ayrıca bu ilişkiler alt boyutlar ve demografik değişkenler itibariyle de incelenmiştir.
HOW DOES THE DEVELOPMENT LEVEL OF COUNTRIES AFFECT OPTIMAL SIZE OF GOVERNMENT: AN EMPIRICAL STUDY WITH PANEL DATA ANALYSIS
Authors: BAYRAK Rıza
Published: March 2021

The aim of this study is to clarify whether there is optimal government size; if there is, to determine whether it changes according to the development level of the countries. Estimations for these research questions were analyzed with the help of the Armey Curve. The economic growth rate was used as a dependent variable; while the annual public expenditure ratio in national income, gross fixed capital formation, unemployment rate were used as independent variables and additionally the effects of the 2008 Global Financial Crisis as a dummy variable. The data were obtained from the World Bank database. 21 countries' data for the period 1990-2019 were analyzed with AMG Panel Data. According to the findings obtained from the study; the existence of optimal public expenditure value has been confirmed in 18 countries except for Spain, Mexico, and Colombia. It has been observed that the optimal public size average is 30.67% in developed countries and 25.43% in developing countries. These results are consistent with Wagner's (1882) argument and Keynesian view. It is possible to say that as the development level of the countries increases, accordingly the public size within the economic structure increases.

Çocuklar okul yılları öncesinde farklı ev ortamlarında bulunmakta ve bu ortamlar gelişimlerini etkilemektedir. Okul öncesi eğitim, özellikle okul öncesi yıllarda öğrenciler arasındaki farkları azaltmak ve öğrencileri eğitime hazırlamak için önemli bir imkân sağlamaktadır. Özellikle sosyoekonomik açıdan dezavantajlı öğrencilerin sahip oldukları dezavantajları büyümeden telafi etmek ve eğitimin başlangıç yıllarında daha eşit koşullar sağlamak için okul öncesi eğitimin önemi birçok çalışmada gösterilmektedir. Bu çalışmada da okul öncesi eğitimin eşitsizlikleri azaltmadaki rolü ile birlikte Türkiye’deki gelişimi incelemiş, mevcut durum ve son yıllarda yapılan iyileştirmeler ele alınmıştır. Okul öncesi eğitimin Türkiye’deki gelişiminin Cumhuriyetin ilk yıllarından itibaren çalışan kadınların çocuklarının bakımını önceleyecek şekilde başladığı ve okul öncesi eğitim veren okulların ilk kez 1961 yılında bir eğitim kurumu olarak tanımlandığı görülmektedir. Kurumsal yapı bağlamında Türkiye’de görülen dönüşüm ile Avrupa ülkelerinde bulunan okul öncesi eğitim kurumlardaki dönüşümler genel bir benzerlik göstermektedir. Türkiye’de bu kurumların fiziki kapasitelerinin ve yaygınlığının artırılması, işbirliği ile oluşturulmuş güncel eğitim programlarına sahip olması ise 2014 yılında olmuştur. Bu yıldan itibaren “Gezici Öğretmen Sınıfı”, “Gezici Sınıf” ve “Taşıma Merkezi Ana Sınıfı” gibi projelerle dezavantajlı öğrencilerin erişimini artıracak projeler ve işbirliklerinin sayısı da artırılmıştır. Tüm bu çabalarla 1992 yılında %5,1 olan okul öncesi okullaşma oranı 2020 itibarıyla beş yaş grubu için %71’e ulaşmıştır. Gerçekleştirilen projeler ve okul öncesi eğitimin önemine yapılan vurgular, 2023 Eğitim Vizyonunun hedeflerinden “5 yaşın zorunlu eğitim kapsamına alınması”na yönelik atılan önemli adımlardır.

Global environmental change makes us aware of the impact of natural hazards. Natural hazards are phenomena with large spatial dimensions and impacts but whose mapping and monitoring data can be recorded only by using satellite or aerial remote-imaging platforms (Poursanidis & Chrysoulakis, 2017). Given that Southeast Asia is the region in the world that is most vulnerable to disasters, it is necessary to implement capacity building for the young scientists in this region so that integrated disaster communities can be developed in their respective countries and possibly in the whole of Southeast Asia. This can be done through summer school, one of the best ways to transfer knowledge. The purpose of this article is twofold: (1) to explain the use of summer school to improve young scientists’ knowledge and understanding of rapid-mapping techniques; and (2) to perform a qualitative assessment of a summer school for rapid-mapping projects. The results of this project showed an increase in the basic science knowledge of the summer school participants (representatives of eight Southeast Asian countries) in terms of initial disaster data provision, field data acquisition using unmanned aerial vehicles, and the rapid-mapping system development design.

The article is devoted to the study of the energy and frequency efficiency of frequency modulated signals with a continuous phase. The values of efficiency indicators obtained from the results of the study made it possible to supplement the existing diagrams of the efficiency of telemetric radio lines with new values. The results of the work simplify the task of selecting signals to ensure information exchange via telemetric radio lines of the cluster under the conditions of restrictions imposed on energy resources. The analysis of efficiency indicators of angular modulation methods used in modern telemetry systems is carried out. The features of the cluster construction of the orbital constellation of small spacecraft are taken into account. The use of frequency modulated signals with a continuous phase is proposed, which makes it possible to increase the energy efficiency of telemetry radio lines due to intersymbol phase connections inherent in this class of signals. Based on the results of the simulation, the values of performance indicators for the proposed signals are determined. Intersymbol phase connections were taken into account using the Viterbi algorithm. The values of the modulation indices of frequency modulated signals with continuous phase, which are of practical interest, are determined. The use of the proposed signals makes it possible to obtain an energy gain of up to 3 dB in comparison with the signals used at present. The values of the modulation indices, the use of which is impractical, are highlighted.

The paper considers prospective directions of improving consumer services rendered with the help of multi-satellite space systems. Based on a study of trends in the development of thematic geoinformation services, the conclusion is made about the need to form personalized complex queries, including those containing suggestions concerning putative solutions for the mass user. The multi-satellite space infrastructure currently under development, which is considered as a single space information system, can serve as the technical means for adopting such an approach. Based on an analysis of development trends of the existing system of geoinformation support, a conclusion is made about the feasibility of the intellectualization and personalization of services, which are targeted at a specific customer, with the expansion of the range of possible consumers to a mass individual consumer. The article proposes several approaches, the further development of which can result in the creation of system-wide services that implement the “from data to solutions” concept at the level of integrated solutions.

A satellite that rotates around the axis of symmetry is considered. A rotor is installed to compensate the angular momentum of the rotating body. Magnetic attitude control system is utilized to provide the stabilization of the rotation axis along the velocity vector on the circular orbit. Control algorithms are proposed that ensure the equilibrium position for the required attitude and its asymptotic stability in the semi-fixed reference frame. Control implementation issues are discussed, including the inherent problems of the magnetic control and the transition to the satellite-fixed reference frame. Numerical simulation is performed for the TNS satellite, which is very far from axisymmetrical. Fast rotation of the satellite around the velocity vector is proved to be achievable with the magnetic control despite the different disturbance sources.

The article proposes a solution to the problem of the variety of physico-mathematical models of EEE-storage life test acceleration by implementing a method based on the analysis of the results of accelerated tests in different modes. The objects of the study are reed relays. The article presents the main physico-mathematical models used for calculating the acceleration factor when simulating storage, as well as sets forth a description of a method for comparing these models. According to this method, the product is tested in various modes and, in accordance with the procedure for accelerated storage life testing based on the prediction of parameter time-dependent degradation, the storage period is estimated. Then, for each model, the storage period estimate is obtained for normal climatic conditions together with the standard deviation. The model with the least standard deviation is considered to be the most suitable for the tested type of product. The physico-mathematical models of the acceleration of reed relay failure mechanisms during storage were studied with the help of this technique; the most suitable is the reverse exponential model.
Turističko brendiranje destinacije na primjeru Podravine
Authors: Baćac Robert , Demonja Damir
Published: March 2021

Podravina kao kulturno-povijesni pojam prepoznatljivo je zemljopisno područje u Republici Hrvatskoj koje obuhvaća teritorij između rijeke Drave, gore Bilogore i Kalničkog gorja. Danas je ovo područje dio jedinstvene administrativne i političke cjeline Koprivničko-križevačke županije. U turističkom smislu Podravina čini zasebnu cjelinu, posebno povijesno, kulturno, prirodno i socijalno odredište s vlastitim specifičnostima i resursima. Turistički gledano, Podravina još nije iskoristila svoju konkurentsku prednost s obzirom na brendiranje, odnosno izgradnju prepoznatljivog imidža te tržišnu prepoznatljivost i pozicioniranost. Brendiranje Podravine je osmišljavanje konkurentnog identiteta koje će diferencirati ovo odredište od svih drugih. Sam brend određuju osnovne karakteristike odredišta, njegove prednosti koje proizlaze iz resursne osnove, što je njegova posebnost, i čini ga prepoznatljivim i različitim od konkurenata. U tom smislu potrebno je detektirati i definirati Točke jednakosti (Points of Parity) i Točke različitosti (Points of Difference) na temelju kojih bi odredište Podravina izgradilo svoje vrijednosti i prepoznatljivosti u turističkom smislu. Za uspješno brendiranje Podravine kao turističkog odredišta potrebno će biti definirati čimbenike brendiranja koji su ključni za izgradnju brenda.
Nature of the common good as the foundation of the community
Authors: Jasiński Karol
Published: March 2021

The subject of interest of the author of the text is the common good as an inalienable element of the organization of the human community. The paper consists of three parts. The first part analyses the need for a common good as the basis of social and political life. The starting point was the distinction of four forms of common life (community, society, political body and state), defining the nature of society, presentation of three forms of relationship between man and society (individualism, collectivism and personalism) and identifying problems related to the definition of the common good. In the second part, the author presented a reflection on the procedural common good in the liberal tradition, the issue of impartiality and identification of the common good in the process of the debate. In the third part, attention is paid to the personalistic view of the common good, which is based on the integral development of personal human nature in the framework of the appropriate institutions and structures. This understanding of the common good is, in the author’s conviction, the best point of reference in social and political life.

U radu se propitkuje mjesto nastanka opsežne rukopisne zbirke usmene književnosti nastale u 19. stoljeću, a pohranjene u Matici hrvatskoj pod imenom uglednoga hrvatskoga kulturnog djelatnika Đure Deželića. Budući da u rukopisu nisu navedeni točno mjesto zapisa niti imena kazivača, o lokalitetu se, kao i o samim zapisivačima, nastoji doznati kroz analizu tadašnjega hrvatskoga teritorijalnog ustroja te kroz jezik, odnosno narječje samoga zapisa usmenih lirskih pjesama. Iz istraživanja se zaključuje da sam Deželić najvjerojatnije nije sudjelovao u stvaranju te rukopisne zbirke kao zapisivač.

U radu je istražen utjecaj dobi/godine studija studenata na njihove stavove prema djeci izbjeglicama, na interkulturalne stavove i na preferencije glazbi svijeta te je ispitana povezanost između stavova prema djeci izbjeglicama, interkulturalnih stavova i preferencija glazbi svijeta. U okviru istraživanja primijenjen je upitnik općih podataka, Skala stavova prema djeci izbjeglicama (Attitude Questionnaire toward Refugee Children – AQReC), Upitnik interkulturalnih stavova (Munroe Multicultural Attitude Scale Questionnaire – MASQUE) te skala procjene za ispitivanje preferencija glazbenih ulomaka na uzorku od 259 studenata Filozofskog fakulteta Sveučilišta u Splitu. Rezultati ne potvrđuju utjecaj dobi/godine studija na stavove studenata prema djeci izbjeglicama ni na njihove interkulturalne stavove. Potvrđen je utjecaj dobi/godine studija na preferencije glazbi svijeta, pri čemu studenti viših godina studija pokazuju veće preferencije takve glazbe. I, konačno, rezultati potvrđuju da studenti koji imaju pozitivnije stavove prema djeci izbjeglicama, imaju i pozitivnije interkulturalne stavove i veće preferencije glazbi svijeta. Autorica ističe važnost interkulturalnog glazbenog obrazovanja za formiranje studentskih interkulturalnih stavova te njihovih stavova prema djeci izbjeglicama.

PRDM16 is differentially expressed in lymph node metastasis in human breast cancer.
Authors: Mamoor Shahan
Published: March 2021

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the breast and the brain reside the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in humans with metastatic breast cancer. We found that PR/SET domain 16, PRDM16, was among the genes whose expression was most different in the lymph node metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. PRDM16 mRNA was present at decreased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of PRDM16 in primary tumors of the breast was correlated with patient distant metastasis-free survival, in lymph node positive patients but not in lymph node negative patients. Modulation of PRDM16 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes and the brain in humans with metastatic breast cancer.
Understanding, Explaining, and Utilizing Medical Artificial Intelligence

Medical artificial intelligence is cost-effective, scalable, and often outperforms human providers. One important barrier to its adoption is the perception that algorithms are a “black box”—people do not subjectively understand how algorithms make medical decisions, and we find this impairs their utilization. We argue a second barrier is that people also overestimate their objective understanding of medical decisions made by human healthcare providers. In five pre- registered experiments with convenience and nationally representative samples (N = 2,699), we find that people exhibit such an illusory understanding of human medical decision making (Study 1). This leads people to claim greater understanding of decisions made by human than algorithmic healthcare providers (Studies 2A-B), which makes people more reluctant to utilize algorithmic providers (Studies 3A-B). Fortunately, we find that asking people to explain the mechanisms underlying medical decision making reduces this illusory gap in subjective understanding (Study 1). Moreover, we test brief interventions that, by increasing subjective understanding of algorithmic decision processes, increase willingness to utilize algorithmic healthcare providers without undermining utilization of human providers (Studies 3A-B). Corroborating these results, a study on Google testing ads for an algorithmic skin cancer detection app shows that interventions that increase subjective understanding of algorithmic decision processes lead to a higher ad click-through rate (Study 4). Our findings show how reluctance to utilize medical algorithms is driven both by the difficulty of understanding algorithms, and an illusory understanding of human decision making.

Harm to some elicits greater sympathy than harm to others. Here, we examine the role of posterior medial frontal cortex (PMFC) in regulating sympathy, and explore the potential role of PMFC in the related phenomena of mentalizing and representing others as connected with oneself. We down-regulated either PMFC or a control region (middle temporal visual area), then assessed feelings of sympathy for and self-other overlap with two characters described as having suffered physical harm, and who were framed as adversarial or affiliative, respectively. We also measured mentalizing performance with regard to inferring the cognitive and affective states of the adversarial character. As hypothesized, down-regulating PMFC increased sympathy for both characters. Whereas we had predicted that down-regulating PMFC would decrease mentalizing ability given the postulated role of PMFC in the mentalizing network, participants in the PMFC down-regulation condition evinced greater second-order cognitive inference ability relative to controls. We observed no effect of the TMS manipulation on self-other overlap, although sympathy and self-other overlap were positively correlated. These findings are discussed as they may inform understanding of the functional role(s) of PMFC in regulating responses broadly linked with empathy.
The Crisis from Above: Gatekeepers Need Better Standards

Improvements to the validity of psychological science depend upon more than the actions of individual researchers. Editors, journals, and publishers wield considerable power in shaping the incentives that have ushered in the generalizability crisis. These gatekeepers must raise their standards to ensure authors’ claims are supported by evidence. Unless gatekeepers change, changes made by individual scientists will not be sustainable.
Understanding, trusting, and applying scientific insights to improve your health: A latent profile analysis approach
Authors: Plohl Nejc , Musil Bojan
Published: March 2021

Various leading causes of death can be prevented or delayed through informed decision-making and lifestyle changes. Previous work has, to some extent, linked such health-promoting behavior (HPB) with variables capturing individuals’ understanding of science, trust in science, and capacity to obtain, process, and apply evidence-based information in the health context. However, empirical research on the relationship between scientific knowledge, trust in science, health literacy, and HPB is scarce. Additionally, no study has investigated whether these characteristics interact to form homogeneous, high-risk subgroups of the population. The present online study (N = 705) revealed that trust in science and health literacy were positively related to a wide array of HPB (e.g., healthy nutrition, physical activity, stress management), while scientific knowledge was only positively associated with COVID-19 vaccination intention. Furthermore, the results of latent profile analyses yielded four subgroups (i.e., low, moderate, and high levels of all three variables and a varied profile exhibiting very low trust in science, low health literacy, and moderate scientific knowledge). The identified subgroups differ significantly in their HPB and other variables of interest. Hence, the present study offers some guidance on which groups may be targeted with public health campaigns and how they may be designed.

Authors: Kunwar Bhim Bahadur
Published: March 2021

This research aims to discover and present the impacts of COVID-19 in tourism in the context of Lumbini and its premises. As COVID-19 spread globally, it has created many challenges in health and security, daily lives, the national economy, and the global tourism industry. The COVID-19 outbreak has been considered as the most challenging tragedy that occurred in the world after the 2nd world war. The World Health Organization (WHO) had listed Nepal also as a country with a high-risk zone of COVID-19.The travel restriction and nationwide lock-down implemented by many countries including Nepal have resulted in a stranded traveler’s movement. As the consequences ticket reservation, flight services, transportation, hotel, and restaurants were closed and several job losses were registered in the tourism sector. The negative effects like fear, threat, frustration, and losing the confidence of tourism entrepreneurs appeared. This has brought changes in the tourists’ behavior and their motivation to travel for the next few years. In Lumbini businesses like lodges, hotels, restaurants, and travel offices were also severely affected by the pandemic. Thus, the tourism sector has been facing serious threats due to the prolonged lockdown and closing of tourism activities than the terror of COVID-19 itself.

Introduction: Hyperbaric Bupivacaine is the most widely used local anesthetic. A number of adjuvants have been used with local anesthetic agents in order to improve the quality and duration of analgesia and anesthesia. This study was carried out to assess the efficacy of intrathecal Tramadol as a spinal adjunct to prolong the duration of spinal anesthesia in lower abdominal surgeries.

Materials and Methods: Sixty patients aged between 18 to 80 years, were randomly divided into two groups - Tramadol and Placebo group. Spinal anesthesia was given by using 25 Gauge Quinke spinal needle in sitting position with midline approach. Patients belonging to Tramadol group received 3 ml of 0.5% Bupivacaine along with 0.5 ml of Tramadol (25mg) and patients belonging to Placebo group received 3 ml of 0.5% Bupivacaine along with 0.5 ml of Normal Saline. In the postoperative ward, duration of analgesia was assessed by the time when first rescue analgesia was given. Visual Analogue Scale for pain was noted at the time of rescue analgesia. The total amount of opioid consumed over 24 hour postoperative period was noted. Hemodynamic like heart rate, systolic, diastolic and mean arterial blood pressures were also noted. Data were analyzed using independent t-test for continuous variables and chi-square test for categorical variables, p value <0.05 was considered significant.

Results: The two groups were comparable with respect to age, weight, sex, ASA grading and duration of surgery. Mean duration of effective analgesia was 231.53 ± 22.00 min in Tramadol group and 125.40 ± 8.86 min in Placebo group (p = 0.001). The mean total amount of opioid consumption in 24 hours postoperative period was 145.00 ± 30.31 mg in Tramadol group and 171.67 ± 36.39 mg in Placebo group (p = 0.003). Mean of Heart rate, systolic, diastolic and mean arterial blood pressures were not significant between the two groups. Incidence of nausea and vomiting was statistically significant between the two groups with a p value of 0.010. Hypotension and bradycardia was statistically not significant between the two groups.

Conclusion: Tramadol was effective adjuvant to hyperbaric bupivacaine for intrathecal use to increase the duration of spinal anesthesia in patients undergoing lower abdominal surgeries.

Published: March 2021

Fish farming is one of the aquaculture activities that most advances in food production and is also one of the most questioned in relation to sustainability, since during the processing of fish, significant amounts of waste are generated, such as head, viscera, fins, tail, spine, scales and remains of meat, which are often discarded inappropriately in nature. These residues in turn have high levels of proteins and lipids, which can be processed and reused for the production of fish flour and oil, obtaining mechanically separated meat, collagen, and gelatin, biofuels such as biodiesel, biogas, and the production of protein hydrolysates and fish protein concentrate. Thus, the objective of the present study was to carry out a bibliographic review on the main technological innovations employed in the use of fish by-products, as a way to add value to this raw material, used for various purposes and to reflect on actions that improve the use and development of biologically active products.

The aim of this study is to report the case of a dog with an esophageal foreign body in a dog, point out the radiographic signs due to that. In addition to talking about the types, radiopacity, frequent location and conduct of the veterinary radiologist in this situation. Foreign body cases are relatively common in dogs. It may be or not a clinical relevance, and it is recommended to be performed with contrasted or simple radiographic exams, complemented with ultrasound and other modalities such as computed tomography and endoscopy. The diagnosis was based on anamnesis, clinical signs and radiographic images of the foreign body. Subsequently, the patient was referred to the operation room for esophagotomy and thoracotomy to remove bone fragments (foreign bodies). The use of radiographic examination was extremely important to determine the diagnosis of esophageal obstruction, allowing for quick referral for surgical intervention.
