From Information Sharing to Information Utilization in Food Supply Chains
Authors: Kiil Kasper , Hvolby Hans-Henrik , Trienekens Jacques , Behdani Behzad , Strandhagen Jan Ola
Published: November 2020

Information sharing has been extensively studied as a key enabler for coordination and integration in supply chains. However, exactly how the shared information is utilized for decision making has only received limited scientific attention in the research literature. The aim of this study is to identify the characteristics of information sharing, and conceptualize how to move from information sharing to information utilization in food supply chains. Using a case study methodology together with a review of the existing literature the authors describe the main facets of shared information - which influence the information utilization in a supply chain - and propose a mapping notation for how these facets can be visualized together with a supply chain operations reference (SCOR) model. Information utilization is especially important because more information sharing does not necessarily result in a better supply chain performance unless the shared information is effectively used in the relevant processes in the chain and well-aligned with the requirements for those processes. The proposed notation provides a systematic structure for mapping the information flows, their specific facets, and helps clarify what information is available and how this information can be utilized in different supply chain processes. Four facets of information sharing are identified and elaborated for food supply chains, together with a mapping tool that emphasizes the information flows and the utilization of information in supply chains.

Authors: Rueda-Velasco Feizar Javier , Monsalve-Salamanca Angie , Adarme-Jaimes Wilson
Published: November 2020

The food assistance programmes (FAP) has the mission to guarantee minimum nutrition requirements in a vulnerable population. Nevertheless, the small deliveries for a spread population, the social conditions, and the limited technological infrastructure could make it difficult to adequately aid supply. To solve these limitations, this chapter proposes a methodology for the design of traceability systems in FAP which allows increasing supply chain visibility, coordination between deliveries and social conditions, and therefore, possible impacts on public policy implications. A qualitative and quantitative comparison of the conventional frameworks is carried out and contrast with the needs of the programmes studied. Also, new criteria are also added to adapt the design to the technological infrastructure and the socio-demographic conditions of the territory. The methodological proposal is applied to the Bienestarina nutritional programme in Colombia, where the technologies and tools to subsequently design the traceability system are proposed.

Published: November 2020

The demand of food is increasing day by day, innovative agricultural practices and sustainable food supply chain management (SFSCM) has gained an emergent importance. Food industries across the globe mainly focus on the manufacturing of their own products to achieve sustainability. The importance of sustainable food supply chain management is to overcome the wastage in food manufacturing industries. In the present research, we identified eleven challenges in the SFSCM on the basis of literature review and expert opinion. The approach is an integration of fuzzy with DEMATEL which can be used for dividing the challenges into cause and effect group. Fuzzy DEMATEL method has continuously been used for the analysis of challenges and is the novel approach for decision making. Thus, this method can be implemented in many fields including automobiles, food industries, retail market etc. From the fuzzy DEMATEL results, it can be confirmed that the Safety and Security is one of the most influencing challenge and has the strongest association with other challenges.

Authors: Negi Saurav , Anand Neeraj
Published: November 2020

India, the world's second-largest producer and one of the centers of origin of Fruits and Vegetables is also one of the biggest food wasters in the world. The challenge of feeding India's billion plus people is not really about agriculture and food production but getting the quality food to the concerned people in a right time. The biggest contributors to this waste are lack of temperature controlled transport and inadequate quality of cold storage facilities for both Farmers and Food sellers i.e. retailers. What India lacks, and needs, is a well-developed, world-class cold chain infrastructure. Without it, India's problems are vast and likely to grow. In this chapter, the authors tries to outlines the extent of Fruits and Vegetables waste in India (at various stages from farm to retail) and its ramifications on food production and safety. Authors also highlighted the challenges faced by cold chain sector in India and a roadmap for improvements. As Indian economy is based on agriculture, development of Cold Chain infrastructure from farm to retail points will play a crucial role.

Published: November 2020

This paper examines the factors that impact the quality of tomatoes during the transportation through the supply chain. This is motivated by the criticality transportation in north India region. Primary data was collected through a survey using a questionnaire with responses from 140 transporters from the Himachal Pradesh and Uttarakhand states of India. The data were analyzed using factor analysis to identify the factors that are impacting the quality of tomatoes during the transportation stage. Based on the analysis, three factors were identified that impact quality: Operational, Preservation and Infrastructure. The identification of these factors will benefit the stakeholders involved in the process of decision-making, like the state government, food processing units, transporters, and the farmers. This will help us to understand the current status of transportation and related issues and challenges which enable them to make better planning and management to improve efficiency in the transportation stage of the supply chain.

Published: November 2020

Food wastage is a huge crisis arising in today's world. An extensive amount of waste generation has become a serious concern of our society in the past years that affects developing and developed countries equally, and according to the Food and Agriculture Organization (FAO), as much as one-third of the food intentionally grown for human consumption is never consumed and is therefore wasted, with significant environmental, social, and economic ramifications. By wasting food, we also waste the time and energy that we have used to produce the food and as well our natural resources and the limited available agricultural land will be used up which could be handled in a much better and sustainable way. Additionally, waste has a strong financial impact and affects the environment including the overall greenhouse gas emission. In an increasingly resource-constrained world, it is imperative to reduce the high environmental, social, and economic impacts associated with this type of waste.
Comparing the Effects of Unsustainable Production and Consumption of Food on Health and Policy Across Developed and Less Developed Countries
Authors: Mbonigaba Josue
Published: November 2020

The unsustainable food consumption across high-income countries (HICs) and low-income countries (LICs) is expected to differ in nature and extent, although no formal evidence in this respect has been documented. Documenting this evidence is the aim of this chapter. Specifically, the chapter seeks to answer the following questions: 1) Do the contexts in less developed countries (LDCs) and developed countries (DCs) make the nature and extent of unsustainability in food consumption different? 2) Do the mechanisms of the linkage between unsustainability of food consumption and health outcomes independent of countries' contexts? 3) Are current policies against unsustainable food consumption equally effective in DCs and LDCs? These questions are answered by means of a systematic review of the literature for the period 2000-2017. The findings are that the nature and extent of unsustainability is quite different across contexts of LICs and HICs.

Published: November 2020

Outstanding advances in educational technology are significantly influencing new learning environments, where it is necessary for teachers to respond and for learners to be able to adapt to the modern age of knowledge and information dissemination. The development of ICT has catalyzed the ability of all types of data to be reproduced visually (visualization). The term visualization refers to the use of various visual aids, which makes a subject more eloquent. This is especially useful for teaching a variety of special courses (environmental education), geography (maps, atlases), history (historical maps, atlases). Geography is a comprehensive and one of the most demanding subjects, as its study deals with a variety of different topics. This course can be made more effective and produce more permanent results through the use of innovative tools. One of these tools is information. In the context of the present study, the use of infographics, a pioneering visual tool transformed into a reliable teaching tool-guide in the classroom, is presented.

Information is a vital concept today. However, the beginning of the information age can be traced back to the periods when clay tablets were used. Information has impact on individual and corporate success. However, information overload occurs when information, whose positive characteristics are highlighted, reaches an excessive amount. Besides, information overload may cause negative consequences. Technostress and information overload, which have negative effects, need to be managed. Information management is useful to reduce the effects of information overload. It will also be possible to deal with information overload through information literacy, which can be taught to individuals. Useful information can only be obtained when these factors are taken into account.
Immigration Is a Nucleus of Economic Development in Africa
Authors: Musitha Mavhungu Elias
Published: November 2020

This chapter demystifies the world view that holds that immigration is motivated by poor people who become the burden to the host countries. It has unearthed that poverty is just a manifestation of a bigger issue which is underdevelopment. Underdevelopment causes migration because the livelihood has been colonised and neo-colonialism continues doing that to this date. This underdevelopment gave rise to poverty, unemployment, inequality, and poor governance. Therefore, immigration is hugely influenced by underdevelopment. Migrants carry along entrepreneurship skills which they also transfer to host countries. However, they also face challenges in the host countries such as discrimination in the allocation of resources such as health and education. The host citizens fear the competition from the new people who have arrived in their country. The African Union should discuss the development of the continent and resolve the underdevelopment through the natural resources the continent has instead of taking it to Europe to perpetuate the notion of underdevelopment.
Reliability Analysis of Multi-Objective Spatio-Temporal Segmentation of Human Motion in Video Sequences
Authors: Hu Yan
Published: November 2020

In view of the problem of uneven distribution of edge contour of multi-target human motion image in video sequence, which leads to the decline of target detection ability, an algorithm of multi-target spatial-temporal segmentation of human motion in video sequence based on edge contour feature detection and block fusion is proposed. Firstly, a multi-target spatial-temporal detection model of human motion in video sequence was constructed, extracting video image frame sequence, using discrete frame fusion method to segment and fuse moving target image, matching moving multi-target in video sequence, secondly segmenting motion features in moving target image, combining with SURF algorithm (speeded up robust features, accelerated robust features) to detect and extract human motion objects in video sequence. The experimental results show that the gray histogram of human motion multi-target space-time segmentation is close to the original image histogram, and the detection and recognition ability of human motion target is improved.

Published: November 2020

Rust detection is necessary for proper working and maintenance of machines for security purposes. Images are one of the suggested platforms for rust detection in which rust can be detected even though the human can't reach to the area. However, there are a lack of online databases available that can provide a sizable dataset to identify the most suitable model that can be used further. This paper provides a data augmentation technique by using Perlin noise, and further, the generated images are tested on standard features (i.e., statistical values, entropy, along with SIFT and SURF methods). The two most generalized classifiers, naïve Bayes and support vector machine, are identified and tested to obtain the performance of classification of rusty and non-rusty images. The support vector machine provides better classification accuracy, which also suggests that that the combined features of statistics, SIFT, and SURF are able to differentiate the images. Hence, it can be further used to detect the rust in different parts of machines.
A Power-Efficient and Quantum-Resistant N-Bit Cryptography Algorithm
Authors: Hongal Rohini S. , Shettar Rajashekar B.
Published: November 2020

With rapid technological advancements and enhanced network growth, security contends to play a crucial role. A powerful network security tends to point out diverse mixture of threats and intimidations and blocks them from creeping and getting circulated into the network to preserve the reliability, confidentiality, integrity, and accessibility of computer networks by annihilating illegitimate admittance and corruption of critical information. Secure hash algorithms (SHA) are cryptographic hash functions used to produce a hash value of fixed output bit sizes. In this paper, an algorithm is proposed to strengthen the cryptographic systems by using reversible logic to generate higher and variable hash values, making it difficult to trace the keys. The proposed scheme is simulated and verified using FPGA Virtex ML505 board, the analysis of power and time of which is carried out using Genus tool, proving it to be efficient in terms of power, gate usage, garbage, and quantum cost.

Published: November 2020

Improving the charge transfer of quantum dots and the electron transport layer can greatly improve the efficiency of quantum dot sensitized solar cells (QDSSC). In this work, we used the ligand exchange method to improve the electron transfer efficiency between CdSe QDs and electron transport layer. The short chain-ligand containing disulfide bond and benzene ring conjugated structure was selected as the surface ligand of CdSe QDs. Because of its unique disulfide bond and conjugated structure, the stability and electron transfer efficiency of QDs in TiO2 layer can be effectively improved. The surface ligand has good stability and the ability to promote charge transfer, which can effectively improve the efficiency of QDSSC. By characterizing of fluorescence performance and the analysis of fluorescence lifetime, the surface of this ligand behaves fluorescence quenching phenomenon and life decay phenomenon after modification. Furthermore, photovoltaic devices constructed by the as-prepared dithiocarbamate functionalization of CdSe@TiO2 have also been assembled with the highest PCE of 5.22%.

Published: November 2020

While physicians advise patients on healthy lifestyle habits, physicians may struggle to abide by their own recommendations. We sought to characterize resident physician participation in exercise, their barriers to exercise, and the effect of exercise on their overall wellness. We hypothesized that residents who exercised would have less depression and greater wellbeing. Trainees at a university-based institution were surveyed. Data regarding exercise habits, hours worked, barriers to exercise, and mental health were acquired. Mental health was assessed via the Patient Health Questionnaire-2. Inter-group differences were analyzed using chi-squared testing; statistical significance was set at P<0.05. 129 trainees responded to the survey. 84 trainees reported exercising while 45 denied. 63 exercisers reported “living a healthy lifestyle” compared to 18 nonexercisers (P<0.001). Exercisers were more likely to report “Time” as their greatest barrier to exercise (P<0.001). Fifty-five exercisers answered “Not at all” when asked about how often they experience anhedonia compared to 23 non-exercisers. Trainees who exercise are more likely to report living a healthy lifestyle and less likely to experience anhedonia than non-exercisers, demonstrating the importance of exercise during residency.
Ruptured axillary artery pseudoaneurysm following an anterior glenohumeral dislocation: A case report
Authors: Rocha Carvalho Diogo , Oliveira-Pinto José , Neves António , Pimenta Santos Joana , Rocha Neves João , Torres João
Published: November 2020

Vascular injuries following anterior shoulder dislocations are rare, with an estimated incidence of 1-2%. The formation of an axillary artery pseudoaneurysm secondary to vascular trauma is a possible late complication and frequently underdiagnosed since it may remain asymptomatic for many years. A rupture of a pseudoaneurysm may occur either from the dislocation itself or after forceful reduction attempts. A ruptured pseudoaneurysm of the axillary artery is a medical emergency and may result in significative upper-limb morbidity or even patient mortality. Nowadays, endovascular techniques have progressively gained ground for the treatment of such lesion, especially in an emergency context. In the present article, the authors present the case of a 77-years-old male patient with a rupture of a pseudoaneurysm of the left axillary artery after repeated forceful reductions of an anterior glenohumeral dislocation and its treatment with percutaneous endovascular stenting.
Superabsorbent polymers in slurry gelling
Authors: Pereira Luiza Fernanda dos Santos , Furlan Marcos Roberto , Fortes Neto Paulo
Published: November 2020

Disposal of solid waste in landfills causes negative impacts on the environment, caused by emissions of greenhouse gases and the release of dark-colored leachate. It’s composition includes high concentrations of suspended solids, heavy metals, salts and organic compounds. Given the above, this study evaluated the use of superabsorbent polymer in the treatment of leachate. Slurry samples were collected at the Taubaté landfill in two seasons to determine electrical conductivity, pH, turbidity, oils and greases. Other samples were submitted to the following treatments: 3.5 g of polymer with 500 g of distilled water, and doses of 3.5; 7.0; 10.5; 14.0; 17.5; 21.0; 24.5; and 28.0 g of polymer with 500 g of slurry, with 4 repetitions each. Other steps, in sequence, were: transformation of the material into gel (gelation), obtaining the liquid volume of water and slurry, and after 0, 12, 24, 48 and 72 h, measurements of polymer dehydration were obtained. The efficiency of doses was determined by the volume of leachate remaining after each treatment. Gelation was more efficient in the summer season, a season with lower values of electrical conductivity, pH, suspended solids, and oils and greases. The most efficient doses in gelation were 10.5 g in summer and 14.0 g in autumn. In conclusion, superabsorbent polymer can be used in the treatment of leachate because it allows its gelling, but the recommended doses vary with the seasons.
City, history, and memory: from a destroyed environment to a constructed one. A case study of Natividade da Serra, state of São Paulo, Brazil
Authors: Gonçalves Mauro Castilho , Santos Michele Rezende , Ciapina Vivian
Published: November 2020

Between 1973 and 1974, the city of Natividade da Serra, state of São Paulo, was relocated in order to provide space to construct a hydroelectric dam for power generation. Based on the idea that the relationship between society and physical space acts to shape and influence the culture of a society, we conducted this study with the principal objective of analyzing the social impacts on the local community by highlighting the cultural transformations provoked by the restructuring of a space that was constructed over the period of a century. By conducting a qualitative analysis of data from the document repository of the City Hall and Parish of Our Lady of the Nativity (Nossa Senhora da Natividade), and from oral sources (descriptions collected through oral history), we elaborated a representative image of daily life in the city as it existed before the restructuring. This reconstruction started with the process of destruction and then proceeded to describe the reorganization of the community in the new space, as well as detailing perceptions of the city as a place that has passed through multiple historical experiences. By relating the data obtained from the written and oral sources to the historical context, we attempted to reveal the political, cultural, and ideological dimensions involved in this process of manipulation of inhabited space. We conclude that the innumerous implications caused by the abrupt transformation of this space has altered the customs and forms of sociability of the population. The analysis of the reasons and motivations for the disappearance of the city suggests that, even if only implicitly, this cultural transformation was desired by those who were in power in Brazil at that moment in time.

Published: November 2020

A field trial regarding the effect of different types of soil cover on the characteristics of bell pepper (Capsicum annuum L. Yolo Wonder) fruit and incidence of weeds was conducted at the facilities of the Department of Agrarian Sciences (UNITAU), Taubaté -SP at 23º02'34" S and 45º31'02" W, with an average elevation of 577 m in a medium-textured dystrophic Yellow Red Latosol. The experimental design was a randomized block with five replicates and four treatments: 1) coat of rice husk (CRH); 2) black polyethylene film (BPF); 3) black biodegradable film (BBF); and 4) soil without cover (SWC), with five replicates. The treatments were distributed in flower beds with 1.2 m wide, 0.3 m high and 10 m long. Drip irrigation was placed on the surface of the beds, with a pipe line (dripping distance 0.4 m, measured flow rate of 1.67 L.h-1, service pressure of 1.6 kPa). Harvesting occurred 90 days after planting the seedlings, and the length, number and weight of the bell pepper fruits were determined. The weed plants in the plot were evaluated in five samples of 0.25 m2 randomly obtained per plot. The coverings had a significant effect on fruit length, number and weight, and black polyethylene film and biodegradable film obtained better results, compared to the coat of rice husk and soil without cover. In the coverings with polyethylene film and biodegradable film, the fruit length was above 12 cm, the number of fruit exceeded 10 fruit per plant and the weight of the fruit was superior to 1 kg per plant. Polyethylene film and biodegradable film reduced weed infestation by 75.4% on average when compared to soil without cover. It can be concluded that the biodegradable film presented the same efficiency as the polyethylene film as regards the productivity of the pepper crop and the reduction of weeds.
Laplacian growth and sandpiles on the Sierpiński gasket: limit shape universality and exact solutions
Authors: Chen Joe P. , Kudler-Flam Jonah
Published: November 2020

We establish quantitative spherical shape theorems for rotor-router aggregation and abelian sandpile growth on the graphical Sierpiński gasket (SG) when particles are launched from the corner vertex.

In particular, the abelian sandpile growth problem is exactly solved via a recursive construction of self-similar sandpile tiles. We show that sandpile growth and patterns exhibit a

(2\cdot 3^n)

-periodicity as a function of the initial mass. Moreover, the cluster explodes – increments by more than 1 in radius – at periodic intervals, a phenomenon not seen on

\mathbb{Z}^d

or trees. We explicitly characterize all the radial jumps, and use the renewal theorem to prove the scaling limit of the cluster radius, which satisfies a power law modulated by log-periodic oscillations. In the course of our proofs we also establish structural identities of the sandpile groups of subgraphs of SG with two different boundary conditions, notably the corresponding identity elements conjectured by Fairchild, Haim, Setra, Strichartz, and Westura.

Our main theorems, in conjunction with recent results of Chen, Huss, Sava-Huss, and Teplyaev, establish SG as a positive example of a state space which exhibits “limit shape universality,” in the sense of Levine and Peres, among the four Laplacian growth models: divisible sandpiles, abelian sandpiles, rotor-router aggregation, and internal diffusion-limited aggregation (IDLA). We conclude the paper with conjectures about radial fluctuations in IDLA on SG, possible extensions of limit shape universality to other state spaces, and related open problems.
Czeski historyk Jaroslav Bidlo i jego udział w ruchu neosłowiańskim przed I wojną światową
Authors: Ďurčanský Marek
Published: November 2020

Czech historian Jaroslav Bidlo and his involvement in the neo-slav movement before World War I The Czech historian Jaroslav Bidlo (1868–1937) was one of the few Austro-Hungarian scholars who possessed vast and critical knowledge in the field of history of Slavic nations. His knowledge was based on his own experience gathered in Polish and Russian academic circles before World War I. As a professor of the Czech Charles-Ferdinand University he was involved in the so-called Neo-Slav movement, which culminated in the “Slavic Congress” in Prague in July 1908, and in the edition of a collective monograph about the Slavic nations (Slovanstvo, Prague 1912). Bidlo used these opportunities to create his own synthetic concept of Slavic history, which he later successfully developed during the interwar period.

Phương pháp gia công bằng chất lỏng phi Newton là phương pháp đơn giản để gia công các bề mặt cầu phức tạp. Trước đây, đối với các bề mặt cầu, để gia công mài tinh ta phải trải qua nhiều bước gia công phức tạp để đạt độ nhám bề mặt theo yêu cầu. Để đơn giản hoá quá trình gia công, hạt mài sẽ được trộn với chất kết dính để tạo thành một hỗn hợp dung dịch mài và khi chuyển động hỗn hợp dung dịch mài này sẽ tạo ra ứng suất cắt tác động lên bề mặt cần gia công. Trong bài báo này sẽ nghiên cứu ảnh hưởng của tốc độ mài, nồng độ dung dịch mài và kích thước hạt mài đến độ nhám bề mặt chi tiết và lượng vật liệu được cắt bỏ. Kết quả thí nghiệm cho thấy rằng, tốc độ mài ảnh hưởng rất lớn đến chất lượng bề mặt gia công và lượng vật liệu được cắt bỏ. Tốc độ gia công càng tăng thì lượng vật liệu cắt bỏ càng lớn và độ nhám bề mặt càng giảm. Bên cạch đó, nồng độ dung dịch mài cũng ảnh hưởng đến chất lượng bề mặt gia công như tốc độ mài. Còn kích thước hạt mài dường như không ảnh hưởng đến chất lượng bề mặt gia công mà chỉ ảnh hưởng đến lượng vật liệu được cắt bỏ. Cuối cùng, kết quả độ nhám bề mặt cầu bằng thép có đường kính Ø32 mm sau khi gia công giảm từ Ra = 110 nm xuống còn Ra = 13 nm.

Many factors affect the bank’s profitability. Internal factors include total asset (TA), and market share loan (MSL) are an important one to consider while external factors include gross domestic product (GDP), corporate income tax (CIT), corruption perception index (CPI), and political instability (PI) are critical. We measured the bank’s profitability through profit before tax on asset (PBTA) and return on asset (ROA) and finds its connection with banks’ internal and external factors. Our empirical estimates based upon 15 commercial banks’ data listed on Pakistan stock exchange (PSE) from 2007-16 show that total asset (TA) and corruption perception index (CPI) is the important one to determine the bank’s profitability. These results have been further justified under the fixed effect regression model which was found appropriate under the Hausman specification test. It is concluded that total assets (TA) and corruption perception index (CPI) does affect the bank’s profitability internally as well as externally.

La psicología, a diferencia de otras profesiones, no tiene un criterio unificado de intervención sino una multiplicidad de enfoques que direccionan la actuación profesional. El papel de los principios éticos en el ejercicio profesional del psicólogo es una actividad que lo coloca en situaciones en las que se ve comprometido en la toma de decisiones, frente a circunstancias en las que se cuestiona su proceder profesional y las consecuencias de este. (Alfaro, 2012). Partiendo de esto, se han conformado organizaciones para regular el accionar de los profesionales de la salud mental, tal es el caso de la centenaria American Psychological Association (APA), la cual ya en 1938 creó su Comité de ética científica y profesional (Pope & Vetter, 2016). A partir de la fundamentación de los enfoques éticos y cada principio, en esta investigación se pretenden identificar semejanzas y diferencias éticas de los enfoques psicológicos de mayor incidencia, y también relacionar los principios deontológicos propios de cada enfoque psicológico con los principios éticos propuestos por la APA.

COVID-19 PANDEMİSİNİN TÜRKİYE’DE DİJİTAL BANKACILIK ÜRÜN VE HİZMETLERİNİN KULLANIMI ÜZERİNDEKİ ETKİSİ
Authors: BEYBUR Mustafa , ÇETİNKAYA Murat
Published: November 2020

2019 Aralık ayında Çin’in Wuhan kentinde ilk olarak görülen Covid-19 tüm dünyayı etkisi altına almış ve 11 Mart 2020 itibariyle Dünya Sağlık Örgütü(WHO) tarafından pandemi olarak ilan edilmiştir. Covid-19’un pandemi olarak ilan edilişi ile aynı tarihte Türkiye’de ilk Covid-19 vakası kayıtlara girmiştir. Covid -19’un pandemi olarak ilan edilmesi ile birlikte ülkeler, pandeminin yıkıcı ekonomik etkilerini azaltmak adına, hem para politikaları, hem de maliye politikalarını eş zamanlı olarak uygulamaya koymuşlardır. Pandemiyi kontrol altına almak için uygulamaya konulan tedbirler, tedarik ve tüketim zincirinde aksaklıkların ortaya çıkmasına, ekonomilerin üretim kapasitelerinin düşmesine, bazı sektörlerde üretimin tamamen durmasına neden olmuştur. Bunun sonucunda ülkeler pandeminin yarattığı negatif etkileri ortadan kaldırmak için farklı politika stratejileri belirlemişlerdir. Tüm dünya ülkelerinde olduğu gibi Türkiye de pandeminin etkilerini önleyici sağlık önlemleri ve bununla birlikte ekonomik önlemler almıştır. Pandemi tüm sektörleri etkilemiştir ancak bankacılık sektörü diğer sektörlerden ayrışarak, gerek dijital kanalların kullanımı ile gerekse likidite sağlayan kurumlar olarak pandemi sürecinde sektörler arasında baş aktör olarak görev yapmaktadır. Bununla birlikte pandemi sürecinde hastalığın bulaşıcılığı temas vasıtasıyla olduğundan dolayı temasın minimum seviyeye indirilmesi gerekliliği ön plana çıkmış ve tüm sektörlerde dijital dönüşüm zaruret haline gelmiştir. Pandemi ile birlikte dijitalleşme daha stratejik bir önem kazanmış ve salgın tüm sektörlerde dijital dönüşümün hızlanmasına neden olmuştur. Bankacılık sektörü ise dijitalleşme açısından diğer sektörlere nazaran pandemiye daha hazırlıklı olan bir sektör konumundadır. Bu çalışmada dijitalleşme konusunda diğer sektörlere göre daha ileri düzeyde olan bankacılık sektörünün dijital ürün/hizmetlerinin kullanım verileri analiz edilmiş ve bu analiz sonucunda pandeminin dijital bankacılık ürün/hizmetlerinin kullanımı üzerindeki etkisi açıklanmaya çalışılmıştır. Çalışmaya ait analizde halen devam etmekte olan Covid-19 pandemisinin başladığı günden günümüze kadar olan süreci ve öncesini içerisine alan 2019 Eylül ve 2020 Eylül dönemleri arasındaki bir yıllık sürece ait dijital bankacılık ürün/hizmetlerine dair verilerden yararlanılmıştır.

Reuse of materials from waste streams is pertinent to achieving sustainable forest production. The enormous wood residues generated at sawmill and the disposal of wood based products poses threat not only to sustenance of the forest resources but also has negative adverse effect on the environment. Limitation exists in the utilization of wood residues as raw material for panel board production in developing countries.

This study examined the physical and mechanical properties of graded density fiberboards produced from varying mixture of sawdust and corrugated paper (pulp) at Forestry Research Institute of Nigeria (FRIN) in 2019. A 2x9 factorial experiment in one way analysis of variance was used to test for significant difference between the factors (density and mixing ratio) considered. The result shows that densities of all boards produced varied with mixing proportions. The densities increased with increasing content of corrugated paper. Boards produced at 0.45 g/cm3 showed higher density (0.648 g/cm3), bending strength (MOR) (1.47 N/mm2) and less water absorption (118.69 %) than those produced at 0.65 g/cm3 having values of 0.58 g/cm3, 1.32 N/mm2 and 153.67 %  respectively. However boards produced at 0.65 g/cm3 had higher elasticity in bending (MOE) (209.19 N/mm2) and less thickness swelling (6.29 %) than those produced at 0.45 g/cm3 having values of 74.87 N/mm2 and 10.88% respectively. Panel G (20:60:20), E (30:50:20) and I (10:70:20) of sawdust: corrugated paper: urea formaldehyde respectively showed superior features in physical and mechanical properties with panel I been the best mixture. Conclusively, wood residues (sawdust and corrugated paper) are suitable raw material for fiberboard production.

Public awareness of foods that have physiological functions for health is increasing. Consumption of orange fleshed sweetpotato not only meets carbohydrate requirements but also beta-carotene which is good for eye health. The aim of this reserach was to evaluate the yield potential and levels of dry matter content of promising clones of orange fleshed sweetpotato rich in beta-carotene. The study was conducted in Malang, East Java in Dry Season II 2016. Genetic materials used were 20 sweetpotato clones, including Beta-1 and Beta-2 varieties as a check. The treatment design used a randomized block design with three replications. The results showed that the clones tested had a potential yield ranging from 20.9 - 35.1 t/ha with an average of 25.2 t/ha. There were three clones  had a higher yield potential than the check varieties Beta-1 and Beta-2. Dry matter content ranged from 17.0 - 31.6% with an average of 25.7%. Fifteen clones had higher levels of dry matter content than check varieties Beta-1 and Beta-2. MSU 14018-06, MSU 14001-20 and MSU 14027-02 clones had high yield potential and dry matter content. All three clones have the opportunity to be released as new superior varieties of orange fleshed sweet potato rich in beta-carotene.
