Authors: Lukito Ruben , Pasaribu Yannes
Published: August 2021

Mayoritas, masyarakat rural hidup dari pertanian. Menurunnya sumber daya manusia mengakibatkan diperlukan alat yang dapat membantu petani untuk mengolah lahannya. Akan tetapi, alat pertanian tidak selalu digunakan sepanjang tahun. Oleh karena itu, tujuan dari perancangan ini adalah mendesain alat mekanis yang multifungsi untuk digunakan di daerah rural, terutama dataran tinggi. Pencarian data menggunakan metode studi literatur mengenai penelitian sebelumnya mengenai kebutuhan transportasi di daerah rural serta pertanian untuk mengetahui kondisi secara umum. Interview serta observasi di Desa Cisondari, Jawa Barat dilakukan untuk mencari informasi mengenai kebutuhan secara khusus. Dari studi literatur serta interview dan obervasi memberikan kesimpulan yang sama mengenai adanya kebutuhan alat transportasi yang multifungsi untuk menunjang kehidupan sosial masyarakat rural. Akan tetapi, belum ada alat transportasi yang dapat digunakan oleh petani untuk mengolah lahan di dataran tinggi. Oleh karena itu diperlukan sebuah konsep alat mekanis yang dapat digunakan untuk berbagai aktifitas di lahan serta untuk kebutuhan sosial seperti mengangkut barang dan manusia. Keilmuan penulis terbatas pada desain dan konsep, maka diperlukan pengembangan dari keilmuan lain untuk menyempurnakan konsep desain. Meskipun demikian, dengan adanya konsep desain pada penelitian ini, para pembuat alat mekanis dan multifungsi untuk desa dapat menggunakannya sebagai pertimbangan dalam mengembangkan produknya, sehingga dapat menjawab kebutuhan masyarakat rural
Kompromisitas Antara Kreasi dan Produksi Produk Berbahan Baku Bonggol Jagung
Authors: Masri Andry
Published: August 2021

Didasarkan pada hasil penelitian sebelumnya, diperoleh kesimpulan bahwa karakteristik bonggol jagung sebagai sebuah bahan baku alternatif dapat menghasilkan produk yang dapat menjadi komoditi yang memiliki peluang ekonomi yang baik. Hal ini sangat didukung oleh kenyataan bahwa bonggol jagung dapat dengan mudah diperoleh hampir diseluruh wilayah Indonesia, dan hingga saat ini belum dimanfaatkan secara ekonomi. Penelitian sebelumnya baru membuktikan bahwa bonggol jagung dapat dijadikan sebagai bahan baku yang mampu memberi nilai keunikan pada produk yang dihasilkan. Penelitian saat ini ditekankan pada aspek efesiensi produksi yang dikompromikan dengan aspek kreasi yang sebelumnya memberi penekanan pada keunikan produk, yang dijadikan sebuah nilai tawar bagi komoditi yang dihasilkan. Penekanan ini diberikan karena pada penelitian sebelumnya variabel kecepatan produksi, karakteristik mesin produksi yang sesuai belum digunakan. Dengan penekanan pada aspek produksi dan kesesuaian mesin produksi diharapkan kreasi berbahan baku bonggol jagung dapat menjadi salah satu komoditi industri yang realistis. Untuk dapat menjadi komoditi industri, diperlukan bentuk produk (kreasi) yang layak industri, efesien dan efektif dari sisi produksi sejalan dengan tetap memiliki kualitas visual yang mendukung terhadap nilai pemasaran. Penelitian akan diawali oleh evaluasi terhadap desain produk berbahan baku bonggol jagung yang pernah dihasilkan. Evaluasi ditekankan pada efesiensi yang dapat dihasilkan oleh mesin yang saat ini digunakan. Hasil evaluasi akan menghasilkan kriteria terhadap kemampuan mesin yang seharusnya tepat digunakan. Paralel terhadap perancangan mesin produksi tersebut, akan dirancang beberapa desain yang tetap memiliki nilai visual yang baik akan tetapi memiliki kesesuaian dengan produk yang dirancang. Melalui metoda beberapa kali iterasi terhadap eksperimentasi akan diperoleh kriteria bentuk yang layak industri dan mesin produksi yang sesuai dengan karakteristik bahan baku konvensional tersebut. Hal ini sangat diperlukan karena bonggol jagung memiliki karakteristik material sendiri yang berbeda sehingga menuntut adanya kesesuaian dari mesin-mesin produksi yang saat ini ada secara konvensional. Hasil penelitian menawarkan sekitar 24 produk prototype kreasi berbahan baku bonggol jagung yang teruji yang dihasilkan oleh mesin produksi yang layak secara industri dan pasar sebagai tawaran baru bagi dunia usaha di Indonesia.

公益广告的言语角色分析
Authors: 方 言清
Published: August 2021

公益广告在告知大众重要的社会问题，并激发他们采取积极行动方面发挥非常重要的作用。基于系统功能语法的言语角色，本文对从美国较有影响力杂志中，随意选取17篇公益广告进行言语角色分析。研究发现公益广告语篇的两个言语角色：给予信息和求取积极行动。给予信息基本上都是通过完整陈述句来表达的，然而，省略陈述句和反意陈述句同样可以实现这一言语功能。省略句的使用显示广告者试图营造与读者的亲密氛围从而缩短两者之间的距离。求取行为主要是通过祈使句，然而疑问句和陈述句同样可以实现这一功能。公益广告语篇中，祈使句的频繁使用显示广告者更高的社会地位；同时，公益广告语篇中还有一些对抗反应和问题答案。这个研究表明反驳陈述和问题答案都是广告说服目的的产物。

Published: August 2021

École à distance, cours asynchrone, cours en ligne synchrone : la pandémie mondiale entraine une scolarisation des élèves à la fois en présentiel et en virtuel. Le présent article propose une réflexion sur l’école virtuelle. Basé à la fois sur des observations de parents-chercheurs et des écrits scientifiques, l’article met en relief les points positifs et négatifs liés à l’école virtuelle. Il ressort notamment que l’école virtuelle ne peut devenir une solution à long terme, et ce, ni pour les élèves et leurs enseignants, ni pour les parents. L’école virtuelle constitue donc une solution d’urgence à court terme pendant la pandémie.

The reconstruction of past environments has been studied in several areas of science, aiming to help in understanding the several events that occurred on the planet. Plants are considered environmental markers and usually show structural adaptations that are characteristic of their habitat. Therefore, after passing through the charring process, they may not be completely consumed by the fire, being possible to find remnants of charcoal and other remaining materials. Based on this, the presence of charcoal is an evidence of the occurrence of current or past fires, contributing with a valuable source of (paleo) environmental proxy data. In this sense, the objective of this work is to assess the physical and chemical changes that occur on scraps of logs from Araucaria columnaris. It will be done during the charring process in muffle, at different temperatures, allowing us to assess important influences in relation to its forming process. The charring temperatures of the logs in natura were in a range of 50 to 1000 ° C, with ranging temperatures from 50 to 50 ° C, and heating ramp of 25 °C min-1. The analysis of this result seeks to allow the proposal of a methodology that assists in the characterization of the natural processes involved in the forming of this type of material, serving as a contribution to (paleo) environmental inferences.

This work describes the approach of a situation of potential risk to health due to nitrate contamination in water intended for human consumption, found in a study conducted in 88 municipalities in the Northeast region of the State of São Paulo (Brazil). 4,347 public water supply samples were analysed for 21 physico-chemical and 2 microbiological parameters. A municipality was distinguished from the others with regard to higher nitrate levels, while the principal components analysis showed that it belonged to a group of 14 municipalities (nitrate group). The Sanitary Surveillance Group was then contacted and, after confirmatory tests in new public water supply samples, analyses were performed on water samples from 16 wells in the county. The groundwater contamination was found, and technical meetings were held. One of the deliberations was the repetition of water analyses of the 16 wells. Consolidated results showed that the 5 wells had nitrate levels above the maximum value permitted by legislation. To mitigate nitrate groundwater contamination of that municipality actions are being taken as a result of 3 technical meetings already held. The other municipalities of the nitrate group are being monitored.

The current scenario of water scarcity and the increasing need to protect the environment show how vulnerable nature is to human actions and retakes the importance of applying smarter water uses. For this reason, the reuse of effluents should be seen as an alternative to attenuate the imbalance generated by the lack of management of water resource. The objective of this work is to analyze the feasibility of reuse of the treated sewage in the Arrudas TEP, located in Sabará - MG, in secondary activities and non-potable uses within the ETE itself or in nearby regions. For this, a bibliographical research was conducted to guide the evaluation of the effluent so that the treated effluent was in accordance with the parameters established by the Environmental Legislation and did not offer public health risks. Data were collected from the ETE for the evaluation of the effluent quality and correlation with the norms dictated by the Norms and, finally, the possible alternatives of effluent reuse were evaluated. The results clarify that it is possible, according to the class of treated sewage, to reuse for nobler purposes in order to avoid the direct discharge of the effluent into the bodies of water.

This work has been performed to test pure membranes of two zeolites as effective adsorbents for the removal of the cationic dye acridine orange (AO) from aqueous solution. The membranes were made through fast and easy method without additional reagents. Membrane made by 5A and 13X zeolites were called m-5A and m-13X, respectively. Adsorption of AO was studied in a batch system in conjunction with UV-visible analyses to determine de efficiency of m-13X and m-5A. Both membranes exhibited good adsorption performance. The influence of contact time on the amount of dye adsorbed onto membranes was investigated, showing high reduction in the first hours of contact. The adsorption efficiency after 18h was 85 % for m-13X, and 55% for m-5A. The kinetics of adsorption showed good agreement with the pseudo-second order model, giving an adsorbed amount of 1,73 and 2,36 mg/g for m-5A and m-13X, respectively. This study shows that m13X is a more effective adsorbent than m-5A for removal of AO from aqueous solutions.

The green synthesis of silver nanoparticles aims to synergistically bind bactericidal properties of the element with the chemical composition of plant extracts and potentially use them in biodegradable plastic substitute materials. In this work, a degradable gelatin film was prepared with silver nanoparticles synthesized with aqueous extract of garlic (Allium sativum); the nanoparticles were previously characterized by ultraviolet-visible spectrophotometry, electron scanning microscopy and electron transmission microscopy. To make the film, pure gelatin, gelatin - carboxymethylcellulose - glycerol, and gelatin - arabic gum mixtures were tested, obtaining the desired texture only with gelatin, at different concentrations. The film with the greatest flexibility was 10% gelatin, with puncture resistance of 47 N and density of 0.943 g/mL. This film was analyzed by infrared spectroscopy, finding modifications of the spectrum dependent on the presence of silver nanoparticles-garlic extract. The electron scanning microscopy revealed a uniform distribution of silver in the film (74.4nm) with an abundance of 56.20% and a concentration of 1.58 mg/g determined by atomic absorption spectrophotometry. Finally, the prepared gelatin film is resistant, amber colored, with possible bactericidal properties due to the presence of silver nanoparticles and easily degradable at 50°C in water.

The Itaipu Technological Park Foundation in partnership with Itaipu Binacional develops actions in the western Paraná/Brazil purposing the promotion of a regional dialogue on basic sanitation and its relevance on health. Therefore, a methodology of technical support to public management was developed for Basic Sanitation and Solid Waste Plans, in consonance with the counties reality and contributing to universal access to sanitation services and legal compliance. According to the Brazilian Policy on Basic Sanitation (Federal Law 11455/2007), municipalities should plan their public services in the four axes, and in this context, the processes that define the support methodology we redefined, such as: assistance to prioritization of the social dialogue; technical support for diagnosis and formulation of goals and projects; and institution of the Municipal Policies. This study presents the methodology applied in Pato Bragado/PR, where the motivation of the county’s technicians was observed, as well as the effectiveness of social mobilization and the awareness of municipal management as key points for boosting sanitation actions. Since it is provided and supervised by the Public Administration, basic sanitation planning is not delegable. However, the possibility of intervention presented as a viable alternative for reinforcement of the duty, technical strengthening of the planning, and guarantee of legal compliance, presenting great return.

The Apogee of India - Nepal relations under NDA First Modi Government
Authors: Ahmad Afroz , Roopnarain Usha
Published: August 2021

The last Indian parliamentary election held in 2014, proved to be the finest example of India’s age-old commitment towards the pinnacle of democratic norms. India had set a niche by conducting the largest democratic franchise in history. First time ever since the 1984, Bharatiya Janata Party (BJP) achieved the majority in the Lok Sabha without clubbing with coalition partners. It also got the absolute mandate to rule India’s federal government by ending the Congress monopoly. Interestingly, the Prime Ministerial candidate Narendra Modi in his campaigns criticized Congress-led United Progressive Alliance II (UPA II) for its impotency towards establishing friendly and cooperative relations with India’s neighbors. He also gave assurance that if his party (BJP) got the mandate, his leadership would adopt appropriate measures to resuscitate convivial ties with neighbors. Since forming the government, Prime Minister Modi has been persistently trying to pursue those promises by proceeding towards friendly ties with India’s neighbors. In the light of above discussion, this paper seeks to critically analyze the progress in Indo-Nepal relations under BJP government led by Prime Minister Narendra Modi.

Authors: Hussain S`hahzadi Saima , Fatima Syeda Sitwat , Shafqat Tanveer , Qazi Qudsia
Published: August 2021

Objective: To determine the fetal outcome of Caesarean Sections (CS) performed for abnormal Cardiotocography (CTG)

Material and Methods: This retrospective data review was conducted in Gynaecology and Obstetrics unit B of Lady Reading Hospital Peshawar from June 2015 till June 2016 after approval from the hospital ethical committee, using a non-probability convenient sampling technique. The hospital record of 234 patients who had CS for fetal distress was reviewed. Patients with singleton and term gestation, who had CS for fetal distress diagnosed based on abnormal Cardiotocography were included in the study.  The fetal outcome was noted in terms of Apgar score at 5 minutes, admission to neonatal intensive care unit (NICU), and perinatal mortality. Fetal blood sampling (FBS) and postnatal analysis of fetal arterial blood gases and PH were not carried out in any patient because of non-availability. The results are expressed in frequencies and percentages, shown in tables and figures.

Results: In one year, a total of 1255 C-sections were performed. Amongst these, 234 (18.64%) patients fulfilling inclusion criteria were enrolled. Babies delivered with 5 minutes Apgar score of 7 or above were 166 (70.94%).  Twenty-one (8.97%) babies were admitted to NICU and perinatal mortality was 6 (2.54%). 

Conclusion

Out of 234 patients who underwent CS due to abnormal CTG, more than 2/3rd of patients had normal babies with an Apgar score of 7 or more, which indicates that abnormal CTG alone should not be used as an indication for CS

Introduction: The main objective of this study was to estimate the prevalence of different diseases based on histopathological features in biopsies from Patients in Swat, Malakand Division, Khyber Pakhtunkhwa. Microscopy often puts in a lot of information and it is for this reason that it is more and more performed especially in patients undergoing surgery for various problems relieved with surgical excision and also in cases of diagnostic uncertainty.

Method: About 73 biopsies, as received sequentially in Anwar Clinical Laboratory Swat from 07 January 2019 to 10 April 2019, from different patients who had visited different Specialty Clinics in Public and Private Hospitals of Saidu Sharif Swat, were reviewed. All the biopsies were reported by the pathologist and histopathological results were analyzed with statistical methods.

Results: The highest prevalence rate was from diseases belonging to Female Reproductive System which was 23 %. The prevalence of GIT and dental diseases was 19% each, prevalence of skin diseases was 18%, prevalence of diseases from Breast and Lymph Nodes was 07% each, prevalence of Male Reproductive System   was 4% and prevalence of Thyroid diseases was 3%. Total carcinoma cases found were 05 with a prevalence rate of (5/73x100= 6.89) or 07%. The mean age of affected patients was 35.43 (SD: 19.21) with a peak prevalence in the group between 20 and 39 years. Prevalence gradually decreased after age 40 with a slight surge between 60 and 75 years.  

Conclusion: The study concluded that the prevalence of different diseases   is low in male as compared to female with one unusual behavior noted and that is all carcinoma patients are from the male category.

Effect of Mn and Zr Addition on Microstructure, Wear and Corrosion Behavior of Ti-6Al-4V Composite Biomaterials Produced by Powder Metallurgy
Authors: ÇUĞ Harun , ERHAİMA Mohamed E. E.
Published: August 2021

In this study, composite biomaterials were produced by powder metallurgy (P/M) method. Ti-6Al-4V master alloy and different proportions of Mn and Zn have been added to this alloy. Dry wear test and electrochemical corrosion test in Hank fluid (Body fluid) were applied to the produced composite P/M materials. The addition of Mn in the produced materials was effective in improving the wear behavior of the Ti-6Al-4V composite material. In addition, the addition of Zr provided excellent corrosion resistance in Hank's solution. The superior properties of Ti-6Al-4V composite material with its microalloy approach are quite challenging for biomedical applications. The best wear resistance was achieved by adding 2%Mn to Ti-6Al-4V by weight. In addition, it was observed that the phases formed as a result of the addition of 2% Zr act as a barrier during corrosion.
The effect of Eurosystem asset purchase programmes on euro area sovereign bond yields during the COVID-19 pandemic
Authors: Hondroyiannis George , Papaoikonomou Dimitrios
Published: August 2021

We investigate the effect of Eurosystem Asset Purchase Programmes (APP) on the monthly yields of 10-year sovereign bonds for 11 euro area sovereigns during January-December 2020. The analysis is based on time-varying coefficient methods applied to monthly panel data covering the period 2004m09 to 2020m12. During 2020 APP contributed to an average decline in yields estimated in the range of 58-76 bps. In December 2020 the effect per EUR trillion ranged between 34 bps in Germany and 159 bps in Greece. Stronger effects generally display diminishing returns. Our findings suggest that a sharp decline in the size of the APP in the aftermath of the COVID-19 crisis could lead to very sharp increases in bond yields, particularly in peripheral countries. The analysis additionally reveals a differential response to global risks between core and peripheral countries, with the former enjoying safe-haven benefits. Markets’ perceptions of risk are found to be significantly affected by credit ratings, which is in line with recent evidence based on constant parameter methods.

Síndrome de Burnout en policías latinoamericanos: revisión
Authors: Torres-Vences Irene Noemí
Published: August 2021

Policemen comprise a professional group that tends to develop stress. The Burnout Syndrome may develop as a consequence of chronic work stress, giving rise to both physical and psychological alterations and increasing the risk of suffering certain diseases. On the other hand, it deteriorates the professional performance of police officers. Between the years 2000 and 2010, 89 studies were conducted relating to this syndrome within Latin-American countries, in which health care professionals and school teachers were the main focus groups; only 8 of said studies evaluated public security professionals. The results showed that the highest levels of Burnout Syndrome were found among Mexican traffic officers, with a 59.4% prevalence among all the participant officers. Given the increase in violence and the rate of crimes in Latin America, it is essential to analyze how working conditions impact the health of those who make up public security institutions, as determining factors in policies and strategies to reduce insecurity.

The main goal from this article is characterize the web apps developed as grade works, in Systems Engineering's program of Nariño University; as a first step for usability evaluation. This effort was carried out under empiric-analytic approach, of descriptive type. The object population of the study was the web apps developed as a grade works in Systems Engineering's program of Nariño University the years between 2010 and 2017. As a result, web apps were characterized, bearing in mind the variables: quantity, technology, economic sector, development time, involve and current state. Was identified 71 grade works that developed web apps, where PHP is the back-end language used and a high level does not identify the use of front-end frameworks. In intermedium level, the web apps were developed by one student only. In a high level the web apps were to public entities, being the sectors: education, government and service; the most bounties. The work enables us to conclude that the lowest use of web apps, obey to the relation between software architecture and usability. The intermediate use of back-end web frameworks and the low level of use of front-end frameworks, is a factor that decreases the flexibility to implement usability architectonic tactics a web app. Moreover, teamwork has to be encouraged and propitiate, when software is build.

Authors: Castillo Ledesma Dorian
Published: August 2021

Many opportunities have been missed, such as taking advantage of available resources or making strategic investments in considerably less amounts than those arranged in crazy studies instead of promoting truly relevant projects,so this situation will continue to be a drag on our country and will keep us relegated from a leading role wich is accompanied by long-term benefits. If we do not take an accurate and timely turn towards a fixed north, by defining and implementing policies and enough resources in logistics, we will continue to be the buyers of services and openning ways for other countries to continue establishing the rules of the game, prices, conditions and restrictions within the area considered since three decades (and for the future) in the cornerstone and countries' survival factor: a strong Supply Chain structure. The so-called “Northern Border Logistics Network” in Ecuador, has the ideal characteristics to connect at least 3 continental regions in the southern hemisphere, becoming a real alternative to fully explore other commercial and tourist benefits of the region, also linking 4 countries in South America indeed. Let's analyze this case, from which interesting conclusions will be gotten.
