Published: February 2022

Purpose – the Tourism-Led Economic Growth Hypothesis (TLGH) is fundamental to the development of the tourism countries. The following research stresses the ever-growing importance of knowledge and creativity– through various disciplines – on national competitiveness and overall economic and tourism development. Emphasis will be given to the particulars of the tourism industry, the achieved level of economic growth, the tourism and economic competitiveness as well as the level of creativity. The study asserts that the nation’s economic and tourism development corresponds to the acquired competitiveness and creativity level. Methodology – the relationship between the variables which indicate economic and tourism development, knowledge, competitiveness and creative economy, will be examined through the comparative study on the case of EU countries (EU28). Multiple linear regression model (MLR) is tested on the case of Croatia (IBM SPSS). Findings – in today’s global crisis, one of the ways to promote economic wealth and growth is supporting service and creative industries. Tourism, as a part of the economic growth model, has a strong positive impact on the creative economy and competitiveness. The optimal development model of tourism economies is global comprehensive approach and it encompasses multidisciplinary relationship with all economic activities. Competitiveness, creativity, economic and tourism growth can be used as variables in forecasting tourism demand and tourism consumption. Contribution – the research’s contribution is reflected in a comprehensive study of the competitiveness and creative economy with a particular emphasis on tourism. The proposed macroeconomic model forms an excellent basis for the conduction of an economic policy and the employment of the appropriate instruments.

Published: February 2022

Purpose – The purpose of the study is to determine the impact of COVID-19 pandemic on tourism and other economic sectors included in the tourism value chain in Croatia. The evaluation of total effects is important in order to evaluate effectiveness of policy measures introduced by Croatian government. Methodology – The estimation of COVID -19 effects on Croatian economy is based on standard input-output model. The open I-O model quantifies indirect effects generated in the tourism value added chain. Closed I-O model estimates induced effects related to the decrease in the net disposable income of the employees which participated in the tourism sector production chain. Findings – Strong reduction in international tourism caused by COVID -19 resulted in significant decrease in activity of many other industries. Besides hotels and restaurant, the most affected sectors were transport, trade, food industry, sports and entertainment services. Total value of indirect and induced tourism effects is bigger than value of direct effects in terms of employment and value added because of multiplier effect. Government subsidies in the form of income support for companies which retained employees have only short-term and limited effects. Negative COVID -19 effects were partially mitigated by output rise in other domestic sectors. GDP decline was more pronounced than GVA since indirect taxes, notably VAT and excise duties were particularly sensitive to negative trends in tourism activity. Contribution – The methodology applied provides the reliable analytical background for analyses of impact of negative exogenous shock affecting tourism and total Croatian economy and assessment of government policy response effectiveness

Authors: Ásványi Katalin , Fehér Zsuzsanna , Jászberényi Melinda
Published: February 2022

Purpose –The purpose of this study is to identify the criteria for sustainable museums found in reference literature and specified in our research, and to suggest guidelines for museums to follow. Methodology –In our primary research, the criteria for a sustainable museum were interpreted along four pillars, for which in-depth expert interviews were conducted with Hungarian museum professionals. Semi-structured interviews were used to explore the viewpoints, expectations, and perceptions of museum staff. Findings – In terms of environmental sustainability, Hungarian contemporary museums place less emphasis on making the museum building itself more sustainable. However, it is worthwhile for institutions that have long-term plans to become more and more eco-friendly. The issue of economic sustainability is the most problematic for Hungarian museums, which can be greatly improved with an active support community that helps museums either through volunteer work or financially. From a social point of view, one of the most important tasks of museums is to ensure equal opportunities, to reach the widest possible range of people, which is facilitated if the museum can function as a community space that adequately involves museum visitors and if it continuously strengthens its role in education. In terms of cultural sustainability, the responsibilities of museums are collection management, maintaining quality, and artistic vitality. Contribution – We conceptualize and provide a framework for sustainable museums. Through our research, we have contributed to broadening the theoretical background of sustainable museums from the perspective of contemporary art museums.

This paper concentrates on the features of the game and the potential benefits of geocaching for the region. The article also explains the reason why geocaching can be treated as an attractive tool of regional communication and promotion. Methodology – Desk research method and own research including semi-structured interviews among Officers of Polish Marshal’s Offices (14 out of 16 in Poland) were applied to achieve the paper’s purpose. In addition, the data obtained from the websites: www.geocaching.pl and www.geocaching.com was analysed as a source for market information. Findings – Findings from the literature review show that players expect geocaching to play an informative, educational, and promotional role. Geocaching is perceived as an attractive tool to showcase the region. Findings from interviews show that regional Officers treat geocaching as a modern tool that can be used to build the region’s image and present its values. Contribution – This article proved that geocaching could become a useful and an attractive informative, educational, and promotional tool for regions. Since this kind of game is not commonly used by regional managers in Poland, it is important to analyse its possibilities. As such, this paper is of value to region management seeking solutions to present and make the region more recognizable.

Authors: Sörensson Anna , Schmudde Ulrich
Published: February 2022

Purpose – The purpose of this paper is to gain a deeper understanding of the concept of shadow destinations. What added value do shadow destinations create for the main attraction in a region? How can a shadow destination create a value of its own? Methodology – The study was constructed as a qualitative multiple-case study. Five different shadow destinations in Sweden were selected based on stratified selection. Sweden was divided into five regions, and one destination from each region was identified. Data were collected through interviews, observations and written materials during 2019–2020. Findings – The findings show that shadow destinations are highly dependent on some sort of main attraction in the region. The results also show that there exist different types of relationships between the shadow destinations and the main attractions. The results also show that shadow destinations can create value for tourists in order to become more important for tourism in the region, as well as to become main destinations by themselves. Contribution – The theoretical contribution from this study shows that the concept of shadow destinations has not been addressed to any great extent in tourism research and that this concept requires further studies. This study makes a contribution to tourism development of shadow destinations.
Multi-Objective Optimization of Periodical Objectives within a Process
Authors: Okello Moses Oyaro
Published: February 2022

Multi-objective optimization (MOO) is an optimization involving minimization or maximization of several objective functions more than the conventional one objective optimization, which is useful in many fields. Many of the current methodologies addresses challenges and solutions that attempt to solve simultaneously several Objectives with multiple constraints subjoined to each. Often MOO are generally subjected to linear inequality, equality and or bounded constraint that prevent all objectives from being optimized at once. This paper reviews some recent articles in area of MOO and presents deep analysis of Random and Uniform Entry-Exit time of objectives. It further break down process into sub-process and then provide some new concepts for solving problems in MOO, which comes due to periodical objectives that do not stay for the entire duration of process lifetime, unlike permanent objectives which are optimized once for the entire process duration. A methodology based on partial optimization that optimizes each objective iteratively and weight convergence method that optimizes sub-group of objectives are given. Furthermore, another method is introduced which involve objective classification, ranking, estimation and prediction where objectives are classified based on their properties, and ranked using a given criteria and in addition estimated for an optimal weight point (pareto optimal point) if it certifies a coveted optimal weight point. Then finally predicted to find how far it deviates from the estimated optimal weight point. A Sample Mathematical Tri-Objectives and Real world Optimization was analyzed using partial method, ranking and classification method, the result showed that an objective can be added or removed without affecting previous or existing optimal solutions. Therefore suitable for handling time governed MOO. Although this paper presents concepts work only, it’s practical application are beyond the scope of this paper, however base on analysis and examples presented, the concept is worthy of igniting further research and application.

Dietary Restriction And Lifespan: Adaptive Reallocation Or Somatic Sacrifice?
Authors: Piper Matthew , Zanco Brooke , Sgrò Carla , Adler Margo , Mirth Christen , Bonduriansky Russell
Published: February 2022

Reducing overall food intake or lowering the proportion of protein relative to other macronutrients, can extend lifespan in diverse organisms. A number of mechanistic theories have been developed to explain this phenomenon, mostly assuming that the molecules connecting diet to lifespan are evolutionarily conserved. A recent study using Drosophila melanogaster females has pinpointed a single essential micronutrient that can explain how lifespan is changed by dietary restriction. Here, we propose a likely mechanism for this observation, which involves a trade-off between lifespan and reproduction, but in a manner that is conditional on the dietary supply of an essential micronutrient – a sterol. Importantly, these observations argue against previous evolutionary theories that rely on constitutive resource reallocation or damage directly inflicted by reproduction. Instead, they are compatible with a model in which the inverse relationship between lifespan and food level is caused by the consumer suffering from varying degrees of malnutrition when maintained on lab food. The data also indicate that animals on different lab foods may suffer from different nutritional imbalances and that the mechanisms by which dietary restriction benefits the lifespan of different species may vary. This means that translating the mechanistic findings from lab animals to humans will not be simple and should be interpreted in light of the range of challenges that have shaped each organism’s lifespan in the wild and the composition of the natural diets they would feed on.

Authors: Ravasi Damiana , Mangili Francesca , Huber David , Azzimonti Laura , Engeler Lukas , Vermes Nicola , Del Rio Giacomo , Guidi Valeria , Tonolla Mauro , Flacio Eleonora
Published: February 2022

Background: In Switzerland, Aedes albopictus is well established in Ticino, south of the Alps, where surveillance and control are implemented. The mosquito has also been observed in Swiss cities north of the Alps. Decision-making tools are urgently needed by the local authorities in order to optimize surveillance and control. Methods: A regularized logistic regression was used to link the long-term dataset of Ae. albopictus occurrence in Ticino with socio-environmental predictors. The probability of establishment of Ae. albopictus was extrapolated to Switzerland and more finely to the cities of Basel and Zurich. Results: The model performed well, with an AUC of 0.86. Ten so-cio-environmental predictors were selected as informative, including the road-based distance in minutes of travel by car from the nearest cell established in the previous year. The risk maps showed high suitability for Ae. albopictus establishment in the Central Plateau, the area of Basel and the lower Rhone Valley in the Canton of Valais. Conclusions: The areas identified as suitable for Ae. albopictus establishment are consistent with the actual current findings of tiger mosquito. Our approach provides a useful tool to prompt authorities’ intervention in the areas where there is higher risk of introduction and establishment of Ae. albopictus.

Authors: Zhao Fei , Tomita Machiko , Dutta Anirban
Published: February 2022

Abstract—Low-frequency Fahræus–Lindqvist-driven (not blood pressure-driven) oscillations in the small vessels are crucial because oscillations in small vessels support nutrient supply. Understanding of this is critical in type 2 diabetes mellitus (T2DM) to develop therapeutic measures to prevent Alzheimer's Disease Related Dementias: vascular factors contribute to cerebrovascular disease as well as mild cognitive impairment and dementia, which are predicted to affect 152 million people by 2050 (Alzheimer's Disease International London, UK, 2019). In this clinical study, we performed functional near-infrared spectroscopy (fNIRS) of the forehead to investigate the effect of the Mini-Cog with three-item recall test on the prefrontal cortex (PFC) activation and the relative oscillatory power in the 0.01–0.02-Hz (Fahræus–Lindqvist effect) and 0.021–0.052 Hz (smooth muscle autonomic innervation) frequency bands in elderly (60 years and older) T2DM and age-matched controls. We found a significant (p<0.01) difference in the PFC activation between elderly subjects with T2DM and age-matched elderly controls. Moreover, power spectral density (PSD) analysis revealed a significantly lower relative power in 0.021–0.052 Hz (smooth muscle autonomic innervation) frequency band in elderly subjects with T2DM during the Mini-Cog three-item recall test. Furthermore, a drop in the oscillatory power in the 0.01–0.02-Hz frequency band during Mini-Cog three-item recall test was found more pronounced in the elderly subjects with T2DM. Therefore, our study highlighted portable brain imaging to capture cerebrovascular reactivity to cognitive load that may provide a biomarker of cerebrovascular dysfunction in T2DM.Clinical Relevance— Our study establishes forehead portable brain imaging for monitoring cerebrovascular function in T2DM under cognitive load.

Published: February 2022

Plant geneticists and breeders have used marker technology since the 1980s in quantitative trait locus (QTL) identification. Marker-assisted selection is effective for large-effect QTL but has been challenging to use with quantitative traits controlled by multiple minor effect alleles. Therefore, genomic selection (GS) was proposed to estimate all markers simultaneously, thereby capturing all their effects. However, breeding programs are still struggling to identify the best strategy to implement it into their programs. Traditional breeding programs need to be optimized to implement GS effectively. This review explores the optimization of breeding programs for variety release based on aspects of the breeder’s equation. Optimizations include reorganizing field designs, training populations, increasing the number of lines evaluated, and leveraging the large amount of genomic and phenotypic data collected across different growing seasons and environments to increase heritability estimates, selection intensity, and selection accuracy. Breeding programs can leverage their phenotypic and genotypic data to maximize genetic gain and selection accuracy through GS methods utilizing multi-trait and, multi-environment models, high-throughput phenotyping, and deep learning approaches. Overall, this review describes various methods that plant breeders can utilize to increase genetic gains and effectively implement GS in breeding .

This study suggests using AI algorithms in user research tasks for mining variables ranging from the tone of voice, image banks, historical records, and product use to determine where brands sit and where there could be competitive advantages. This study reviews the current design processes of User Experience (UX) designers and the advancements in Deep Learning (DL). It identifies potential areas of automation in the Preparation, Incubation and Illumination stages of the design process. It recognises the possibility of using Long Short-Term Memory (LSTM) models to automate design feedback and the creation of alternate designs with Generative Adversarial Networks (GANs).
Are Deep Models Robust against Real Distortions? A Case Study on Document Image Classification
Authors: - Saifullah , Siddiqui Shoaib Ahmed , Agne Stefan , Dengel Andreas , Ahmed Sheraz
Published: February 2022

Deep neural networks have been extensively researched in the field of document image classification to improve classification performance and have shown excellent results. However, there is little research in this area that addresses the question of how well these models would perform in a real-world environment, where the data the models are confronted with often exhibits various types of noise or distortion. In this work, we present two separate benchmark datasets, namely RVL-CDIP-D and Tobacco3482-D, to evaluate the robustness of existing state-of-the-art document image classifiers to different types of data distortions that are commonly encountered in the real world. The proposed benchmarks are generated by inserting 21 different types of data distortions with varying severity levels into the well-known document datasets RVL-CDIP and Tobacco3482, respectively, which are then used to quantitatively evaluate the impact of the different distortion types on the performance of latest document image classifiers. In doing so, we show that while the higher accuracy models also exhibit relatively higher robustness, they still severely underperform on some specific distortions, with their classification accuracies dropping from ~90% to as low as ~40% in some cases. We also show that some of these high accuracy models perform even worse than the baseline AlexNet model in the presence of distortions, with the relative decline in their accuracy sometimes reaching as high as 300-450% that of AlexNet. The proposed robustness benchmarks are made available to the community and may aid future research in this area.

Published: February 2022

Bangladesh's railway system mostly uses typical manual railway crossing technique or boom gates through its 2,955.53 km rail route all over the country. The accidents are frequently happening in the railway crossings due to not having obstacle detectable and quickly operating gate systems, and also for fewer safety measures in the railway crossing. Currently, there are very few automatic railway crossing systems (without obstacle detectors) available, however, all of them are dependent on the national power grid without a backup plan for any emergency cases. Bangladesh is still running a bit behind in the power generation of its consumption, hence it is not possible to have a continuous power supply at all times all over the countryside. We aim to design and develop a smart railway crossing system with an obstacle detector to prevent common types of accidents in the railway crossing points. We design to use two infrared (IR) sensors to operate the railway crossing systems which will be controlled by the Arduino Uno. This newly designed level crossing system will be run with the help of sustainable renewable energy which is cost-effective, eco-friendly, and apply under the national green energy policy towards achieving sustainable development in Bangladesh as a part of the global sustainable goal to face climate change challenges. We have summarized the simulated results of several renewable energy sources including a hybrid system and optimized the Levelized Cost of Energy (LCOE), and the payback periods.

Published: February 2022

HIV infection invariably attracts the attention of medical staff in complex medical specialties. To achieve the goal of elimination by 2020, various approaches are required, including the establishment of prevention, diagnosis, monitoring, treatment, control measures. These should be supported by statistical studies that report on restricted or extended geographical areas, to the level of social class and age. Such an approach, combing the medical and social science perspectives (medicosocial) can prove useful for developing control measures. Due to the complexity of this immunodeficiency pathology, the condition also attracts comorbidities (most notably tuberculosis). Hence, prospective strategies need to be developed and oriented towards the goal of eradicating HIV infection. This paper presents strategies for consideration.

Published: February 2022

The paper contains the results of the 100-hour test campaign of the Additive Manufactured (AM) spare part (retainer – slipper) dedicated for an exact axial piston pump. The material of the retainer-slipper has been identified by using energy dispersive spectroscopy and replaced by other – with similar material properties as the original one. The obtained spare part had been subjected to only one postprocessing type (sandblasting) to analyze the influence of the rough part after the AM process. The whole test campaign has been divided into stages, where after each stage microscopic measurements have been made. During microscopical investigation roughness and geometrical measurements were conducted. The results revealed that it is possible to replace parts in hydraulic pumps with the use of AM. 100-hour test campaign caused about 500% increase in the surface roughness of the pump’s original part which was cooperated with the AM spare retainer-slipper, without any damages to the test system.

Authors: Georgiev Dejan , Delalić Sentilija , Zupančič Križnar Nina , Socher Achinoam , Gurevich Tanya , Trošt Maja
Published: February 2022

Background: Continuous subcutaneous apomorphine infusion (CSAI), levodopa-carbidopa intestinal gel infusion (LCIG), and deep brain stimulation of the subthalamic nucleus (STN-DBS) have markedly changed the treatment landscape of advanced Parkinson’s disease (aPD). Despite a similar outcome of all device-aided therapies (DATs), some patients switch or combine DATs. The aim of this retrospective study was to explore the frequency and reasons for switching between or combining DATs in two movement disorders centres in Slovenia and Israel. Methods: We collected and analysed demographic and clinical data from aPD patients who switched between or combined DATs. Motor and non-motor reasons and their frequency for switching/combining were examined, as was the effect of DAT using the Global Improvement subscale of the Clinical Global Impression Scale. Non-parametric tests were used to analyse the data. Results: Of 505 aPD patients treated with DATs at both centres between January 2009 and June 2021, we identified in total 30 patients (6%), who either switched DAT (N=24: 7 LCIG-to-STN-DBS, 1 LCIG-to-CSAI, 5 CSAI-to STN-DBS, 8 CSAI-to-LCIG, 1 STN-DBS-to-LCIG, 1 LCIG-to-CSAI-to-STN-DBS, and 1 STN-DBS-to-CSAI-to-LCIG) or combined DATs (N=6: 5 STN-DBS+LCIG and 1 STN-DBS+CSAI-to-STN-DBS+LCIG). In most of these patients, inadequate control of motor symptoms was the main reason for switching or combining DATs, but non-motor reasons (related to the disease and/or DAT) were also identified. Conclusions: Switching between and combining DATs is uncommon, but in some patients brings substantial clinical improvement and should be considered in those who have either inadequate symptom control on DAT treatment or have developed DAT related complications.
The Structure and Meaning of Planck's Constant
Authors: Humpherys David
Published: February 2022

Planck's constant plays an important role in quantum mechanics but has little physical meaning apart from its contribution to the formulas. Evaluating each of the constant's unit dimensions gives a more granular account of the physical phenomena described by the equations. These formulas show how classical and quantum mechanical equations are related, and they give consistent descriptions of phenomena like momentum and energy in classical and quantum systems.
Two-Dimensional Stress Analysis of Isotropic Deep Beams Using the Finite Difference Method
Authors: Fogang Valentin
Published: February 2022

This paper presents an approach to the two-dimensional analysis of elastic isotropic deep beams using the finite difference method (FDM). Deep beams are subjected to in-plane loading and present a shear span to height ratio of less than 2.50; consequently, Euler-Bernoulli beam theory and Timoshenko beam theory do not apply. Deep beams analysis is generally conducted using numerical methods such as the finite element method and to a lesser extent the FDM; the strut-and-tie model and the stress field method are also widely utilized. Analytical approaches usually make use of the Airy stress function, where stresses are formulated in terms of the stress function; however, the exact solution of this function satisfying all of the boundary conditions can hardly be found, even for simple cases. In this paper, deep beams were analyzed using the FDM. The FDM is an approximate method for solving problems described with differential equations. The FDM does not involve solving differential equations; equations are formulated with values at selected nodes of the structure. Therefore, the deep beam was discretized with a two-dimensional grid, and additional nodes were introduced at the boundaries and at positions of discontinuity (openings, brutal change of material properties, non-uniform grid spacing), the number of additional nodes corresponding to the number of boundary conditions at the node of interest. The introduction of additional nodes allowed us to apply the governing equations at boundary nodes and satisfy the boundary and continuity conditions. An Airy stress function approach and a displacement potential function approach were considered in this study whereby strong formulations of equations (equilibrium, kinematic, and constitutive) were set. Stress and stability analyses were carried out with this model; furthermore, deep beams of varying stiffness, layered beams, and beams having openings were analyzed. For slender beams, the results obtained with the Airy stress function approach showed good agreement with those of the Euler-Bernoulli beam theory, and for deep beams, the shapes of stress distributions were in good agreement with a proper understanding of the behavior of structures. On the other hand, the displacement potential function approach delivered unsatisfactory results, probably due to the use of an inefficient equation solver; a more powerful tool will be needed in future research for this purpose.

Kelangkaan air secara global terjadi antara lain karena pertumbuhan penduduk yang tinggi, persaingan penggunaan air, dan perubahan iklim global. Salah satu upaya yang dapat dilakukan untuk mengatasi permasalahan ini antara lain pemanfaatan sumber air alami berupa air hujan. Teknologi yang sudah ada sejak masa lalu sudah diaplikasikan secara luas di berbagai negara, namun di Indonesia belum diaplikasikan secara luas. Teknologi sederhana ini dapat dilakukan pada wilayah dengan curah hujan rendah sampai tinggi, baik di perkotaan maupun pedesaan. Aplikasi teknologi panen air hujan untuk keperluan domestik semakin bermanfaat jika terjadi anomali iklim (El-Nino) dan pada saat defisit air. Rancangan panen air untuk keperluan domestik harus memperhitungkan kebutuhan dan ketersediaan air serta kemampuan teknis dan keuangan. Peran aktif masyarakat dalam perancangan dan pemeliharaan sangat penting untuk keberlanjutan pengembangan teknologinya.

Published: February 2022

Abstract.  Environmentally friendly agriculture is an agricultural system that manages all resources and inputs of the agricultural system to achieve optimal productivity and economic benefits, but has a low risk of resource and environmental sustainability, as well as global warming/climate change. Environmentally friendly implementation strategies lead to synergy and integration between technologies, optimization of resources and production inputs which are carried out through three approaches, namely: (1) Anticipation, adaptation, and mitigation approaches in the context of global warming and climate change, (2) Mitigation approach, countermeasures, and remediation in the context of edhapik and biological environments, and (3) Land remediation approach in the context of degradation and pollution of land, air and ecosystem resources due to excessive use of agrochemicals. Support for research activities and development of adaptation, mitigation and remediation strategies for the restoration of polluted land is expected to increase the economy while producing healthy agricultural products and environment. Various regulations and policies for implementing a sustainable agricultural environment, socialization and implementation in the field must be supported by an agricultural environment information system that is easily accessed by users.
Formation of Logistics Approach to Economic Development of Road Sector of the Republic of Belarus
Authors: Ivut R. B. , Tsarenkova I. M.
Published: February 2022

The paper identifies promising directions in the economic development of the road sector, ensuring the rational use of investments and improving the processes of construction, reconstruction and repair of roads based on the logistics

approach, as well as contributing to the organization of safe and economically profitable transportation of goods and passengers necessary for the sustainable economic development of the country and increasing its transit potential. The set of basic logistics principles is supplemented with applied ones, the application of which will allow to manage the cycle of economic activity in the road sector as a whole. Describing the features of the logistics approach in the field under study, it has been established that the hierarchy of the construction of logistics systems is due to the use of various schemes of control actions, depending on the specifics of the functioning flows of each level. The management of the macro-logistic road management system is based on the need to increase the competitiveness of road transport services by improving the maintenance of transport flows, which is dependent on the level of development of the road infrastructure and the construction of a system for changing its state. The foundation of micro-logistic systems is formed by the resource flows of road construction production, perceived in a systemic unity. The main idea of the logistics approach to the economic development of the road economy is manifested through rational planning (macro-level) and implementation (micro-level) of measures for the development and operation of roads. The requirements of users are the basis for the choice of directions for improving their condition, which links the organization of work on road facilities with the strategy for the development of the transport and logistics system of the country. Organization of transportation of goods and passengers by road is consistent with the processes of road works, which together makes them optimal for each of the areas and the formed system as a whole. The logistics approach provides the necessary connecting framework in the management of intersectoral flow processes for the provision of road transport services and road activities, as well as intra-industry – between road services as part of the logistics system.

Abstract
Quality is conformance to requirement, that is, a product is said to be of quality when it has reached the agreed standard target. This research examines the quality cues found in the sources of Islamic law, namely the Al-Quran and al-hadith. To strengthen the quality management of education according to the perceptions of legal sources and Muslim scholars. The data collection process was carried out through library research. Something is said to have quality when something has a good meaning and vice versa. In the context of education, if someone says a school is a quality, it can be interpreted that the graduates are quality, the teachers are qualified, the building is proper, and so on. To mark something that has quality or not, someone gives symbols with certain names, for example, superior schools, model schools, pilot schools, and so on. Quality is the realization of Ihsan's teachings, which is to do good to all parties because Allah has done well to humans with His various favors, and is prohibited from doing damage in any form.

Mutu merupakan conformance to requirement, yaitu produk dikatakan berkualitas ketika sudah mencapai target standar yang di sepakati. Penelitian ini mengkaji isyarat mutu yang terdapat pada sumber hukum umat islam yaitu al-quran dan al-hadits. Dengan tujuan memperkuat manajemen mutu pendidikan menurut persepsi sumber hukum dan para ahli muslim. Proses pengumpulan data dilakukan melalui studi pustaka (Library Research). Sesuatu itu dikatakan bermutu ketika sesuatu itu mengandung makna yang baik dan sebaliknya. Dalam konteks pendidikan, apabila seseorang mengatakan sekolah itu bermutu, maka bisa dimaknai bahwa lulusannya berkualitas, gurunya mumpuni, gedungnya layak, dan sebagainya. Untuk menandai sesuatu itu bermutu atau tidak seseorang memberikan simbol-simbol dengan sebutan-sebutan tertentu, misalnya sekolah unggulan, sekolah teladan, sekolah percontohan dan lain sebagainya. Mutu merupakan realisasi dari ajaran ihsan, yakni berbuat baik kepada semua pihak disebabkan karena Allah telah berbuat baik kepada manusia dengan aneka nikmat-Nya, dan dilarang berbuat kerusakan dalam bentuk apapun.

Reality, Expectations And Policy Of Madrasah Management In The Era Of Regional Autonomy
Authors: Ahmad Zarkasyi
Published: February 2022

Abstract
The existence of madrasas cannot be separated from Muslims' initial goals and needs for the importance of education. However, the chaotic legal basis also causes the management of madrasas that are not optimal. Education Statistics Data from the Ministry of Education and Culture and EMIS data from the Ministry of Religion of the Republic of Indonesia in 2015 showed the number of madrasas was 76,583 or around 21.31% of the existing schools. By analyzing madrasas, opportunities will be obtained, especially in the era of regional autonomy, and strategies to produce policies intended to strengthen the role and function of madrasas for the community.

Teori Belajar Konstruktivisme Ki Hajar Dewantara serta Relevansinya dalam Kurikulum 2013
Authors: Hawwin Muzakki
Published: February 2022

Abstrak:

Perdebatan panjang terjadi khususnya dalam hal teori belajar. Bermuara pada pertanyaan, apakah siswa dapat mengkonstruk sendiri pengetahuannya atau guru satu-satunya sumber belajar utama? Ki Hajar Dewantara dalam sejarahnya merupakan tokoh awal pendidik Indonesia yang visioner. Beliau membentuk Taman Siswa untuk menentang konsep pendidikan ala Belanda yang menghegemoni dan menjajah (Inferiority complex) kaum pribumi kala itu, sehingga membuat rakyat Indonesia tidak bisa berfikir secara merdeka. Konsep “berfikir merdeka” itulah, yang saat ini ditangkap oleh pemerintah melalui penerapan Kurikulum 2013 dengan pendekatan scientific. Penelitian ini merupakan penelitian literatur yang dianalisis dengan menggunakan hermeneutika filosofis, dengan tokohnya Gadamer. Penelitian ini ingin mengungkap (1) Bagaimana konsep teori belajar konstruktivisme Ki Hajar Dewantara? (2) Bagaimana relevansi pemikiran Ki Hajar Dewantara mengenai teori belajar konstruktivisme dengan Kurikulum 2013? Adapun tujuan dalam penelitian ini untuk memberikan gambaran pemikiran Ki Hajar Dewantara tentang Teori Belajar Konstruktivisme dan relevansinya dengan Kurikulum 2013. Hasil penelitian ini menghasilkan kesimpulan: Pertama, teori belajar konstruktivisme Ki Hajar Dewantara yaitu: (1) Kesetaraan antara Peserta Didik dan Guru (2) Pemanfaatan sumber belajar lingkungan dan budaya (3) Pembelajaran berbasis observasi (4) Pembelajaran merdeka (5) Tut Wuri Handayani. Kedua, pemikiran Ki Hajar Dewamtara atas Relevansinya dengan Kurikulum 2013 dikaji melalui 2 aspek, yaitu: penekanan instruksional serta peran guru dan siswa.

Penelitian ini bertujuan untuk mengungkap praktik peran Kepala Sekolah SDMT Ponorogo dalam mewujudkan budaya kinerja tinggi khususnya padabudaya kinerja tenaga pendidik. Mengingat tenaga pendidik merupakan ujung tombak keberhasilan dalam sebuah pendidikan. Dengan kata lain bermutu tidaknya pendidikan tergantung dari kinerja tenaga pendidiknya. Oleh karena itu, penelitian ini penting dilakukan untuk meningkatkankinerja tenaga pendidik dengan cara merekayasa budaya kerja sehingga menciptakan budaya kinerja tinggi.Hal tersebut dikarenakan berdasarkan penelusuruan belum ada penelitian yang mengupas peran kepala sekolah dalam mewujudkan budaya kinerja tinggi di lembaga pendidikan. Penelitian ini menggunakan pendekatan kualitatif dengan jenis studi kasus. Informan dalam penelitian ini kepala sekolah dan seorangtenaga pendidik. Adapun cara mengumpulkan data dengan metode wawancara dan dokumentasi. Setelah data terkumpul selanjutnya dianalisis dengan konsep dari Miles dan Huberman yang meliputi reduksi data, display data, dan penarikan kesimpulan. Dari hasil analisis menyimpulkan bahwa 1) peran kepala sekolah dalam mewujudkan budaya kinerja tinggi dilakukan dengan sistem collaborative principal rolesyang meliputi peran educator (memberikan pembinaan), motivator (memberikan motivasi kerja), supervisor (mengawasi jalannya kegiatan),leader (memimpin dengan sistem delegasi pada setiap kegiatan), manager (mengelola kegiatan berbasis time schedule). 2) usaha yang dilakukan kepala sekolah dalam menciptakan budaya kinerja tinggi adalah denganpenerapan sistem kerja berbasis full timer dan part timer, penerapan prinsip otoritas dan delegasi, pemantauan kinerja (supervisi), penerapan prinsip keadilan dalam hal insentif, dan penerapan the right man in the right place.

High efficiency non-doped organic light emitting diodes based on pure organic room temperature phosphorescence by high-lying singlet exciton fission

Heavy-metal-free pure organic room temperature phosphorescence (ORTP) holds great potential in the field of organic optoelectronic devices owing to their low economic cost, simple preparation techniques and high exciton utilization. However, it is still filled with challenges in realizing high efficiency organic light-emitting diodes (OLEDs) and exploring the behind internal physical mechanism based on these ORTP molecules. Here, we demonstrate a high performance OLED induced by an efficient interfacial spin-mixing process based on an ORTP molecule, and study the electroluminescence (EL) mechanism through magneto-electroluminescence (MEL) and magneto-photoluminescence (MPL) measurements. The steady-state and transient PL properties imply that the interfacial effect is related to a high-lying singlet fission (HLSF) process in the ORTP molecule, which will not only increase the number of triplet excitons, but also largely enhance the fluorescence lifetime, thus improving the intersystem crossing (ISC) efficiency. Furthermore, the HLSF process and the corresponding energy level position are confirmed by investigating the incident wavelength- and temperature-dependent PL spectra. Based on this interfacial spin mixing effect, the fabricated non-doped OLEDs based on the ORTP molecule as emissive layer exhibit high efficiency, and the external quantum efficiency is as high as 16% with CIE coordinates of (0.27, 0.49) by optimizing the interfacial material adjacent to the emissive layer. The proposed mechanism during EL process will give insight to produce more efficient OLEDs based on ORTP materials in the future.
