House Construction

Salar people are Turkic-speaking Islamic people and an ethnic group with a small population in China. Wattled-wall house of Salar people is a type of traditional house threatened by extinction. In 2008, the wattled-wall house construction skills were selected for the national intangible cultural heritage list. It is mainly distributed in Xunhua Salar Autonomous County, Qinghai Province of China. So far, Salar people′s traditional wattled-wall house knowledge has been poorly documented. Therefore, a study supporting cultural preservation efforts is needed, including preserving plants used in its construction. This study mainly applied ethnobotanical methods based on data collection through observation, interviews, and documentation. Additionally, ArcGIS data analysis is also used to supplement the evaluation of the traditional wattled-wall house. This study aimed to (1) document traditional knowledge about the wattled-wall house construction, (2) and evaluate the current status of the wattled-wall house from different angles like the environmental adaptability and internal advantages and disadvantages. The result showed that the local people still apply the knowledge about the wattled-wall house from generation to generation. However, due to some practical reasons, the wattled-wall house is on the verge of extinction. There are 11 plant taxa used as construction materials in wattled-wall house. Conservation efforts for species involved in the wattled-wall house are needed, especially the ones with limited availability. Re-use of wattled-wall house is needed in order to maximize the economic benefits and to safeguard its historical and architectural values. It is recommended that the conservation of this cultural heritage needs more attention and effort from the local government or the society.

Light weight aggregate concrete (LWAC) has gained popularity as an alternative to ordinary concrete for structural purposes, but its using still needs to get promoted in China. With the intention of shading some lights on LWAC development and broadening its application in China, this paper analyses the development of LWAC. It presents the current status and trend of LWAC application. On the basis of introduction of concept, advantages and disadvantages of LWAC are analyzed. It can be summarized that characteristics such as lightweight, high strength, excellent seismic performance, better fire resistance, good crack resistance, good durability and economic benefits improve its popularity. However, properties like easiness to delaminate and difficulty to pump, as well as problem of shrinkage and creep, limit its application. Owing to its properties, the main application range of LWAC includes high-rise buildings, bridge engineering, sound-absorbing products, and decorating nowadays. It is concluded the use of LWAC will be lead to higher strength and more energy saving in the future. Moreover, the recycling and energy efficiency of LWAC will be further improved.

The purpose of the article is a retrospective analysis of structural transformations of financial and credit relations in the agricultural business, evaluation of the effectiveness and feasibility of the introduction of agricultural receipts as a new instrument of lending to the agricultural business of the regions. Methodology of work – system-structural and comparative analyzes (to determine the effectiveness of the crediting mechanism according to the agricultural receipts of the farmers of the region); monographic (when studying the problems of the functioning of the mechanism of lending to agrarians by agrarian receipts) economic analysis (when carrying out a comparative analysis of the mechanism of classical bank lending to the agrarian business and the mechanism of lending to agrarians according to agrarian receipts); modeling and forecasting (when determining ways to overcome the existing deficiencies in the mechanism of lending to agrarian business entities of the region according to agrarian receipts). The results of the work – a retrospective analysis of the structural transformation of financial and credit relations in the agricultural business was carried out. The mechanism of crediting agrarians according to agrarian receipts and the scale of its distribution in the agrarian business of the region are considered. A comparative analysis of the mechanism of classical bank lending to the agrarian business and the mechanism of lending to agrarians according to agrarian receipts was carried out. In the framework of the pilot project “Agrarian receipts in Ukraine” of the international financial corporation (IFC) in partnership with the Swiss Confederation in Ukraine, the example of the Poltava region defined the effectiveness of the crediting mechanism according to the agrarian receipts of the agrarians of the region. The advantages and disadvantages of the mechanism of crediting the subjects of the agrarian business on agrarian receipts are noted. The ways to overcome the existing shortcomings of the mechanism of crediting the subjects of the agrarian business of the region according to agricultural receipts are determined. Conclusions – according to the results of the conducted research, the effectiveness of the mechanism of lending to the agricultural business of the regions according to agricultural receipts was proved, its advantages and disadvantages were noted, and attention was also focused. Proposed in Art. 7 of Law No. 5479-VI clearly delineate cases and restrictions on the debtor’s reimbursement of expenses incurred by the lender with the acquisition of the right to grow and harvest the pledged crop of agricultural products, which will ensure the principle of equality of parties on economic benefits and distribution of credit risks according to agricultural receipts.

Research into machine learning (ML) for clinical vascular analysis, such as those useful for stroke and coronary artery disease, varies greatly between imaging modalities and vascular regions. Limited accessibility to large diverse patient imaging datasets, as well as a lack of transparency in specific methods, are obstacles to further development. This paper reviews the current status of quantitative vascular ML, identifying advantages and disadvantages common to all imaging modalities. Literature from the past 8 years was systematically collected from MEDLINE® and Scopus database searches in January 2021. Papers satisfying all search criteria, including a minimum of 50 patients, were further analysed and extracted of relevant data, for a total of 47 publications. Current ML image segmentation, disease risk prediction, and pathology quantitation methods have shown sensitivities and specificities over 70%, compared to expert manual analysis or invasive quantitation. Despite this, inconsistencies in methodology and the reporting of results have prevented inter-model comparison, impeding the identification of approaches with the greatest potential. The clinical potential of this technology has been well demonstrated in Computed Tomography of coronary artery disease, but remains practically limited in other modalities and body regions, particularly due to a lack of routine invasive reference measurements and patient datasets.

The international seabed area (i.e., the “Area”) is rich in mineral resources. According to the United Nations Convention on the Law of the Sea (UNCLOS) and the relevant implemented agreements, in 2012, the International Seabed Authority (ISA) began to develop the regulations for the exploitation of mineral resources in the Area. The most important part of the regulations involves determining the distribution of benefits from the exploitation of mineral resources in the Area between the ISA and the contractors. The establishment of a financial model to evaluate the economic benefits and compare the distribution scheme was the basic method relied on in the current study of payment mechanism. According to the characteristics of the exploitation project of mineral resources in the Area, the discounted cash flow method was selected to construct the financial model. Taking China’s deep-sea mineral resources development project in the Area as the background, the main parameters of the model were determined. A comparative study of similar financial models with Massachusetts Institute of Technology (MIT) and other foreign countries was carried out, in addition to a sensitivity analysis of parameters. On the basis of the assurance that the contractor’s internal rate of return was not lower than the level of the land mining enterprise, the financial model was used to calculate the internal rate of return and the revenue of royalty under different payment mechanisms and rates. The advantages and disadvantages of different payment mechanisms in the exploitation of mineral resources in the area were analyzed. Lastly, the possible impacts of deep-sea polymetallic nodule mining on Terrestrial metal markets were highlighted.

Pacific indigenous social work has developed across borders reflecting the diaspora of Pacific peoples outside their homelands. It is proposed that the ‘next wave’ of Pacific social work be centred in Pacific homelands to invigorate new approaches that better address well-being for transnational Pacific peoples. The current status of Pacific social work education, professionalization and theory is discussed. It is argued that social justice, locally-led development and cultural preservation will be better realized with an expansion of Pacific social work across borders. The article reflects on decolonization, universalism–relativism, nature of social work, resourcing and collaborations for Pacific social work.

Abstract Last two decades, the studies on microRNAs (miRNAs) and the numbers of annotated miRNAs in plants and animals have surged. Herein, we reviewed the current progress and challenges of miRNA annotation in plants. Via the comparison of plant and animal miRNAs, we pinpointed out the difficulties on plant miRNA annotation and proposed potential solutions. In terms of recalling the history of methods and criteria in plant miRNA annotation, we detailed how the major progresses made and evolved. By collecting and categorizing bioinformatics tools for plant miRNA annotation, we surveyed their advantages and disadvantages, especially for ones with the principle of mimicking the miRNA biogenesis pathway by parsing deeply sequenced small RNA (sRNA) libraries. In addition, we summarized all available databases hosting plant miRNAs, and posted the potential optimization solutions such as how to increase the signal-to-noise ratio (SNR) in these databases. Finally, we discussed the challenges and perspectives of plant miRNA annotations, and indicated the possibilities offered by an all-in-one tool and platform according to the integration of artificial intelligence.

The Impact

Objectives: Starting from the tobacco economy, this paper studies the “surge phenomenon” of macro-economy in developing countries. Methods: This paper studies the impact of tobacco industry on Anhui economy by using the relevant theories of industrial economics, econometrics and regulatory economics, combined with the actual situation of tobacco industry. Based on the analysis of the overall development of tobacco industry, this paper empirically analyzes the relationship between tobacco industry and Anhui economic growth. This paper combs the relevant literature of the existing research results of this theory. Combined with the special fact that government investment accounts for a large proportion in China’s current economic construction, this paper redefines the hypothesis of the investor in the theory of principles. On this basis, the expected equilibrium results of enterprise investment decision-making under government led and market led modes are compared and analyzed by using incomplete information static game model. Results: When the output value of tobacco industry increases by 1%, it will drive the GDP to increase by 0.373%. Secondly, by comparing the economic benefits of tobacco with the social costs of tobacco, it is found that with the economic development, the social costs caused by tobacco increase year by year, but the economic benefits are slightly greater than the social costs. The difference between the two is also increasing year by year. Conclusion: In the context of tobacco control, we should fully consider the advantages and disadvantages of developing the tobacco industry. Under the excessive intervention of the government, the manifestation of the surge phenomenon is more intense, and the final consequence of overcapacity is more serious than that under the market-oriented mode..

Environmentally sustainable energy sources are called for due to contemporaneous development in industries along with the rapid pace of urbanization. Ethanol produced from biomass can be deliberated as a clean and safest liquid fuel and an alternative to fossil fuels as they have provided unique environmental, strategic economic benefits. For the past decade, it has been noticed that there is an increasing trend found in bio ethanol production which has created a stimulus to go for advancement in bio ethanol production technologies. Several feed stocks have been used for the bio ethanol production but the second generation bio ethanol has concentrated on the lignocellulosic biomass. Plenteous lignocellulosic biomass in the world can be tapped for ethanol production, but it will require significant advances in the ethanol production process from lignocellulosic because of some technical and economic hurdles found in commercial scale. This review will encompass the current status of bio ethanol production in terms of their economic and environmental viability along with some research gaps as well as policy implications for the same.

Increasing Demand

Improving the quality of life and creating various economic benefits, conservation of cultural heritage can contribute to sustainable development as a concept having environmental, economic and socio-cultural aspects. Intangible cultural heritage as the chief reason of cultural diversity particularly guarantee sustainable development. In recent years, the increase in the concern about local ways of life, festivities, has motivated the conservation of intangible cultural heritage specifically, and contributed to the continuity of the implementation of traditional craftsmanship as a domain of intangible cultural heritage and guaranteed the sustainable development. The conservation of traditional craftsmanship necessitates providing the transmission of knowledge between master and apprentice and the continuity of practice. Through 20th century, rapidly changing life conditions, the demand for traditional craftsmanship has noticeably decreased causing the decrease in the number of practitioner craftsmen. It needs to regenerate the organic relationships of crafts with the changing life conditions for their conservation. Tourism can be a motivating force to regenerate interrelations with the increasing demand of tourists for traditional crafts. This paper aims to present the effects of tourism on crafts and discuss specific conservation approach focusing on the sustainable development of historic environments particularly focusing on 17 sustainable development goals highlighted within the 2030 Agenda for Sustainable Development published by United Nations General Assembly in 2015.Keywords: Traditional craftsmanship, tourism, conservation, historic environments, sustainable development

Natural Aggregates

Construction is growing rapidly nowadays. Buildings, housing, industry/business centers and highways will require natural aggregates which are natural resources that cannot be renewed. Therefore, we need replacement materials able to replace these natural aggregate. The large amount of plastic waste in fields, based on existing data, causes environmental pollution through it can be reused and useful for building and road construction. Most of communities don’t even know the plastic waste processing technology that allow their use in the construction of house construction such as floors, walls, roofs, and hinges and also road construction with not heavy road loads. The purpose of this activity is to provide the knowledge to the people of RPTRA related to technology for the use of plastic waste for building materials and also road construction in the area in the RPTRA environment considering it is not a public road and hence, with not heavy vehicle. The method used is firstly observation and interview of several houses visited. Then activities about using different types of plastic waste as construction materials. Finally, evaluation of the progress of the project by conducting a survey to people who had met the criteria of being a member of the plastic waste program. The success of this program will be the people’s understanding and a significate growing of any highvalue plastic use as construction material. The benefit of this community service is to increase the knowledge and insight of the people of RPTRA, South Meruya, and West Jakarta City, related to environmentally friendly technologies such as plastic waste processing.
