MENGALIR DAN MEMBAUR SEBUAH KARYA AKULTURASI MUSIK MINANGKABAU-JAWA
Authors: Santoso Iwan Budi , Darlenis Teti , Arya Pradipta Dana Adi
Published: August 2023

Artistic Research (Art Creation) entitled Flowing and Blending was inspired by the movement and/or migration of Indonesian people from one area to another. This is based on the necessities of life in the area of origin which are considered no longer providing income, so that it has an impact on economic income. The arrival of migrants from an area makes the problem of the culture of origin and those visited sometimes unable to merge. The purpose of this artistic research is to find out the different tone areas. However, in the work Menglir dan Mebaur produces a mixture of musical sounds as measured by the sound ambitus of the instrument when used in cultural communication (music). The process of mutual respect and respect by using the language of communication will be able to flow and blend in the cultural frame, even though both have different backgrounds. Based on the elements of culturalcommunication, it produces cross-cultural values that are mutually respectful and respectful. Musical artwork Flows and Diffuses becomes a manifestation of musical works representing two different cultural elements, however, they can complement each other with the communication language of musical instrument tones when sung. In order to build the musical in this part of the work as a whole, the authors also look for elements of the combination of two cultures, namely Minang and Javanese, with the hope that the concept of assimilation can become a unified musical feeling as amirror or reflection of a togetherness.

Authors: Setiawan Sigit , Wibowo Anggono Kusumo
Published: August 2023

This research reveals the composition of the Reyog Ponorogo gamelan, a case study of the Reyog Sardulo Anurogo group in Jember, East Java, in the context of the 2019 National Reyog Festival. The reason for selecting Sardulo Anurogo as the case study subject is due to the group's interesting pluralism aspect, where Reyog is not only studied by the Javanese Ponoragan ethnic group, but also by other ethnic groups in Jember, Madura. The 2019 National Reyog Festival also marked a significant moment for Sardulo Anurogo, as they achieved a top 3 position in the festival, representing the group's highest achievement. The approach used is based on the ideas of I Wayan Sadra, who proposed four methods for composing music. These are (1) the principle of growth, (2) sound transformation or medium, and (3) range or tonal area. These principles areapplied to analyze the composition of the Reyog Sardulo Anurogo gamelan. The research result is the categorization of Reyog music development methods, which can be used as a prototype for composing and enhancing the creative aspects of Reyog gamelan.

Authors: Liu Zhe , Huanyuan Wang  , Zenghui Sun
Published: August 2023

Effects of different tillage management on the growth and yield of maize were studied from early June to September 2017. The experiment was set up with three tillage treatments: traditional shallow moldboard plow tillage with straw removal (MT), sub-soiling/ plow tillage /sub-soiling rotation with straw mulch (ST) and no-till/sub-soiling/no-till rotation with straw retention (NT). The soil compaction of different soil layers, plant height, chlorophyll content, above-ground biomass and yield were determined through the three tillage practices. Results showed that NT and ST treatments helped to reduce soil compaction, and had a positive effect on maize root growth and development, plant height and chlorophyll content compared to the MT treatment. The chlorophyll value in early growth period under NT and ST increased by 31.8 and 24.6%, respectively, and the plant height was increased by 20.2 and 15.9% compared with MT, respectively. The size order of soil compaction was MT > NT > ST, and the soil compaction value was the maximum at 20 cm under MT treatment, which was 1007 kPa. Meanwhile, NT and ST also increased the plant above-ground biomass and yield of maize. Compared to MT treatment, the dry weight of plants for the NT and ST treatments significantly increased by 24.3 and 15.7%, respectively, and the grain yield significantly increased by 11.9 and 14.9%, respectively (P < 0.05). NT and ST tillage treatments are effective measures to improve structure of soil, contribute to plant growth and development and thereby increase in yield.

Authors: Yanan Li  , Li Qi
Published: August 2023

Taking Fu County, a typical area of Weibei dry plateau, as the research object, the normalized difference vegetation index ( NDVI ) was calculated by using Landsat 8 OLI remote sensing image. On this basis, the vegetation coverage in the study area was estimated and graded according to the binary pixel model, and the dynamic changes of vegetation coverage in the study area from 2013 to 2017 were quantitatively analyzed. Results showed that the overall NDVI value in the study area increased from 2013 to 2017. The vegetation cover in the study area is dominated by extremely high vegetation cover. The coverage area of low, medium and high vegetation cover decreases, and the coverage area of extremely high and extremely low vegetation cover increases. The coverage area of high vegetation and extremely high vegetation cover accounts for more than 75% of the study area. The study area showed a transfer trend of extremely low vegetation→low vegetation→medium vegetation→high vegetation coverage. The vegetation coverage generally developed to a good trend, but there was also a transfer of high vegetation coverage to medium vegetation coverage. The areas with the greatest changes in the study area are mainly concentrated in the northwest and near the southern Damagou, and the high NDVI area of Ziwuling National Nature Reserve has moved eastward and narrowed. Accuracy assessment indicates that the dynamic monitoring using the fused image time series produces results with relatively high accuracy.

Assessment of soil quality in hanzhong city based on risk management of heavy metal pollution
Authors: Wang Tao
Published: August 2023

In the present study, Hanzhong City was taken as an example, and the classification of soil heavy metal pollution risks was performed based on the evaluation of soil fertility status with soil physical and chemical properties as the main indicators. Results showed that the coefficients of variation of soil physical and chemical indicators in the study area were in the descending order: the soil fertility status showed a trend of increasing with decreasing terrain and increasing rivers. The high fertility areas were mainly distributed in the northwest and northeast of the plain area, while the low fertility areas were mainly distributed in the southeastern hilly and mountainous areas and in the western low-lying areas, and the transitional areas surrounded the low-fertility areas. At least 88.89% of the Cd samples and 98.61% of the Cr samples out of the eight heavy metals, Cd, Hg, As, Pb, Cr, Ni, Cu, and Zn, belonged to the priority protection class, while 11.11% of the Cd samples and 1.39% of the Cr samples belonged to the safe use class. The overall distribution of soil quality was similar to that of soil fertility status, while the distribution range of low-quality soil in the southeastern part was smaller and more concentrated. The above research results indicate that the introduction of the classification results of soil pollution risk control types generally reduces the soil fertility status correction and changes the spatial distribution pattern of the original soil fertility status to some extent.

Published: August 2023

An abrupt worsening of the conditions to reproduce the raw material model of the Russian economy forces high-tech enterprises to take a proactive stance of advanced economic development based on the new technological paradigm in terms of the post-industrial age. However, this transition cannot happen on its own accord. This requires a creation of a brand new goal-directed management system, having the implementation of strategic priorities in the long-term development strategy of the enterprise and the possibility of achieving technological sovereignty. One of the approaches to solve this problem implies to introduce process-project management at the enterprise. This can only be achieved through the long-term resource planning and investing in the development of innovative functional capabilities of a large industrial enterprise, increasing innovative capabilities of personnel and involving the staff in the process of strategic development in the frame of a dynamically changing environment.
On Approaches to Designing a “Vivid” Economy
Authors: Varakin Denis N.
Published: August 2023

The study examines approaches to designing an economy capable of life. The purpose of the article is to obtain criteria that satisfy such an economy. The hypothesis is the idea of the ability of the economy to self-propulsion due to the continuous exchange between its elements. Information and knowledge are considered as a universal category that takes part in the processes of exchange. Hence the problem of stability in complex open nonlinear systems is emphasized; a definition is given for the ultra-sustainability of the economy – ​the economy bypasses those states that can lead to a change in sustainability. The author sees the result of the study of the potential for ultra-sustainability in the “vivid” components of the economy: the ability of the economic system to interact with lower and higher levels in the hierarchical structure; definition of meanings and goal setting; prioritization in safety and evolution; subjectivity; production and application of knowledge; processing external chaos and working into its own complexity; functioning feedbacks; the presence of a strong-willed and effective component; accountability mechanism. The research method consists in referring to a systematic and synergistic approach, which makes possible to explain the phenomenon of homeostasis in the economy. Intermediate conclusions are obtained: information and knowledge components can act as a unifying element for exchange processes in the economy. The conclusion that self-completion of a holistic image of the national economy can be carried out with the help of knowledge, which act as a driving and structuring force, is proposed for discussion in economic science.
Problems and prospects for development of the gas industry in the domestic market in 2022
Authors: Gayvoronskaya Maria S.
Published: August 2023

The new conditions for 2022 imply a reduction in natural gas exports from Russia to Europe. We expect an overall reduction in natural gas exports from Russia from 244 bill. cub. m in 2021 to 155 bills. cub. m in 2025. Not only physical export flows, but also financial ones will be reduced, which may change the financial condition of Russian companies and require adjustment of their behavior models and strategies. In such conditions, the development of the domestic natural gas market, which has been discussed for the past 20 years, becomes an extremely topical topic. Therefore, this article will focus on the domestic gas market. The main producers of natural gas in Russia, their operating conditions, tax regulation, access to exports and their role in the domestic market will be analyzed and studied. In addition, domestic gas consumers will be considered and the potential for growth in natural gas consumption in the Russian domestic market, which lies in the growth of the chemical industry and the development of gasification, will be assessed. The article will put forward proposals for rebuilding the existing model of the domestic gas market, such as the abolition of the severance tax on new volumes of gas supplies, expanding the capabilities of independent companies in terms of domestic gas supply and gasification, optimizing approaches to choosing settlements for gasification, allowing all gas companies to export LNG, solving the pricing problem: choosing the optimal model for price liberalization in segments other than households and housing and communal services.

Published: August 2023

The world needs to achieve carbon neutrality or net zero emissions of greenhouse gases (GHG) by 2050. Buildings are major sources of GHG emissions. Applications of the latest innovative technologies of machine learning/A.I. algorithms have opened up new opportunities. The optimal control of cooling plant systems is important to reduce energy consumption and therefore emissions. Knowing the cooling load demand in advance can help facility managers operate cooling plants much more efficiently. This paper presents a real-life application of nine A.I. models for time-series forecasting of the cooling load demand of a commercial building. LSTM neural networks, Facebook Prophet time series model, and DeepAR recurrent neural network models are found to be the most accurate with a Mean Absolute Percentage Error (MAPE) in the range of 15 to 16 with a computing time in the range of 294 to 319 seconds respectively. The LightGBM machine learning model on the other hand proves to be the fastest with a MAPE of 18.96 in just 7 seconds. Thus, different models can be deployed for different requirements. Optimising the operation of cooling systems as per the forecast cooling demand can bring enormous energy savings that are essential for achieving carbon neutrality.

Published: August 2023

En el presente trabajo se estudiaron las características fisicoquímicas de residuos orgánicos generados en el municipio de Suchiapa, Chiapas, México. El objetivo fue caracterizar residuos frutihortícolas: cáscara de calabaza, cáscara de tamarindo, hojas de mazorca de maíz y residuos fecales ganaderos: estiércol de ganado bovino, ovino y aves de corral, para determinar su uso óptimo en la producción de biogás y metano. Los parámetros analizados fueron humedad, cenizas, pH, sólidos totales (ST), sólidos totales volátiles (STV), carbón (C) y nitrógeno (N), aplicando los métodos de las Normas Oficiales Mexicanas (NMX-AA-016 a la NMX-AA-025). Los resultados obtenidos del cálculo de STV, estimaron una producción teórica de 850 L de metano/kg de STV mediante el uso de cáscara de calabaza, siendo el mejor residuo para garantizar la producción de biogás. De este modo, con la caracterización fisicoquímica de los residuos se permite revalorizar el potencial de éstos para la producción de biogás.
In this paper were studied the physicochemical characteristics of organic waste generated in the municipality of Suchiapa, Chiapas, México. The objective was to characterize fruit and vegetable residues: pumpkin peel, tamarind peel, corn cob leaves and livestock fecal residues: cattle, sheep and poultry manure, to determine their optimal use in biogas and methane production. The parameters analyzed were humidity, ashes, pH, total solids (ST), total volatile solids (STV), carbon (C) and nitrogen (N), applying the methods of the Official Mexican Standards (NMX-AA-016 to the NMX -AA-025). The results obtained from the calculation of STV, estimated a theoretical production of 850 L of methane/kg of STV through the use of pumpkin peel, being the best residue to guarantee biogas production. In this way, with the physicochemical characterization of the waste, it is possible to revalue their potential for the production of biogas.

Published: August 2023

Penggunaan nilai akreditasi sekolah untuk klasifikasi sampel berdasarkan level kemampuan matematika tidaklah memadai, mengingat prestasi belajar siswa tidak hanya ditentukan oleh faktor akreditasi, tetapi oleh faktor lain yang bersifat internal dan eksternal dari siswa. Penelitian ini bertujuan untuk: (1) membandingkan nilai akreditasi dan pengelompokkan nilai rata-rata ujian nasional matematika menggunakan analisis klaster dengan algoritma K-Means dari Sekolah Menengah Pertama (SMP) di Kota Cirebon; (2) mengetahui korelasi antara nilai akreditasi dan hasil klasterisasi; (3) mengetahui kelompok SMP yang memiliki kemampuan matematika level tinggi, sedang, dan rendah. Metode yang digunakan adalah metode kuantitatif korelasi. Hasil penelitian menunjukkan bahwa penggunaan nilai akreditasi sekolah sebagai dasar penarikan sampel kemampuan matematika untuk level tinggi (akreditasi A), level sedang (akreditasi B), dan level rendah (belum terakreditasi) menyebabkan bias pada analisa statistik karena peluang benarnya hanya 31,91%. Uji korelasi menunjukkan tidak ada hubungan yang signifikan antara nilai akreditasi dan level kemampuan matematika siswa. Kemampuan matematika level tinggi dan sedang didominasi oleh SMP swasta. SMP yang berstatus negeri mayoritasnya berada pada kemampuan matematika level rendah.Â  Hasil klasterisasi dari penelitian ini dapat digunakan untuk penelitian lanjutan yang memerlukan sampel besar seperti pada teori respon butir modern, pembuatan tes diagnosa, pembuatan tes adaptif, dll.

Common Exceptions: Understanding the U.S. Legal System’s Differential Treatment of Sexual Violence Cases
Authors: Dalton Madison
Published: August 2023

Academics and activists have long decried the state’s poor legal treatment of sexual violence cases. However, literature has struggled to attribute this poor legal treatment to the decisions of state actors, rather than factors outside the state’s control. I present evidence that U.S. chief prosecutors dismiss sexual violence cases at substantively higher rates than commensurate violent crimes, despite sufficient legal evidence for prosecution and a collaborative victim. Given that most chief prosecutors are democratically elected, I theorize that public preferences drive this disproportionately high dismissal. I test this theory using a survey on public violent crime perceptions and a paired profile conjoint experiment. Contrary to expectations, I find respondents prefer to prosecute sexual violence cases at high rates relative to other violent crimes. This relationship holds both when I analyze direct questions about prosecution preferences and when I experimentally control for other variables that may influence prosecution allocation decisions.

Introduction

Female sand flies are hematophagous, feeding on animals and in the process serve as vectors for Leishmania, the parasites that cause leishmaniasis in humans. Leishmaniasis are a group of parasitic neglected tropical diseases in 98 countries including Nigeria and kills ~60,000 people/year. In Nigeria, Sokoto State is endemic to leishmaniasis but there is a knowledge gap on the identity of the prevalent sand flies and the Leishmania species they transmit. Hence, this cross-sectional study was designed to take inventory of the species of sand flies in Sokoto using genetic methods.

Methods

1,260 (310 females) sand flies were collected from three Local Government Areas (L.G.A) of Sokoto State- Wamakko, Sokoto South and Kware. Genomic DNA was extracted from each fly and DNA amplification by polymerase chain reaction (PCR) was carried out on the DNA samples using primers targeting the arthropods mitochondrial cytochrome oxidase subunit 1 (mt-coI) gene, and nested PCR with primers targeting the gene for Leishmania internal transcribed spacer-1 (its-1) of ribosomal RNA its-1rRNA. The PCR products were sequenced.

Results

Gene sequence analysis revealed five species of sand flies belonging to the old-world genera namely Phlebotomus and Sergentomyia. The identified species were P. papatasi (6.45%), S. adleri (6.45%), S. affinis (9.7%), S. distincta (9.7%), S. schwetzi (67.7%). Within the sampling period, sand flies were most abundant in the rainy months of August (104/33.5%) and September (116/37.4%) with all the five identified species occurring. Sequence analysis of its-1 gene identified Leishmania infantum in two sand flies (2/310)- P. papatasi (from Sokoto South) and S. affinis (from Wamakko). BLAST search in NCBI and phylogenetic analysis revealed that the sand fly species are related to the species reported in different parts of Africa, while the L. infantum is identical to strain reported in Brazil (KY379083.1).

Discussion

Phlebotomus papatasi and four species belonging to the genus Sergentomyia are the most prevalent sand flies in Sokoto State, Nigeria and they harbor L. infantum solely. The results shed light on why visceral leishmaniasis is the most predominant form of the disease. Therefore, we recommend that adequate care for dogs must be instituted as dogs are the major animal reservoir for L. infantum.
Controlled attenuation parameters to assess liver steatosis in obese patients with polycystic ovary syndrome
Authors: Wang Dongxu , Nan Nan , Bing Hao , He Bing
Published: August 2023

Objectives

This study was performed to investigate the changes and influencing factors of liver controlled attenuation parameter (CAP) in obese patients with polycystic ovary syndrome (PCOS), and to determine the prevalence and risk factors of nonalcoholic fatty liver disease (NAFLD) in PCOS patients with obesity.

Methods

Forty-one PCOS patients with obesity and twenty age- and body mass index (BMI)-matched control women without PCOS were enrolled in this study. General data, body composition, biochemical parameters, sex hormones, and liver CAP in the two groups were collected and compared. Liver CAP was measured using transient elastography.

Results

NAFLD was more common in the Obese PCOS group than in the control group (75.61% vs. 45.00%, P=0.018). Compared to the control group, the obese PCOS group showed apparent increases in alanine transaminase (ALT), aspartate transaminase (AST), CAP, triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), totle testosterone (TT), free androgen index (FAI), fasting insulin (FIns), and homeostasis model assessment-insulin resistance (HOMA-IR), along with lower high-density lipoprotein cholesterol (HDL-C) and sex hormone binding globulin (SHBG) levels. In addition, as shown by Spearman analysis, liver CAP in PCOS patients with obesity had a positive correlation with ALT, AST, TG, TT, FAI, FIns, and HOMA-IR, and a negative correlation with SHBG. Logistic regression analysis showed that TG, TT, FIns, and HOMA-IR were risk factors for NAFLD, while TT was an independent risk factor for NAFLD in PCOS patients with obesity.

Conclusion

PCOS patients with obesity had a significantly higher prevalence of NAFLD. Furthermore, in PCOS patients with obesity, liver CAP was associated with disorders of lipid metabolism, insulin resistance, and hyperandrogenemia, with elevated testosterone levels being an independent risk factor for NAFLD in PCOS patients with obesity.
Spatiotemporal characteristics and the national variations of borderland use change in Laos within the geopolinomical context
Authors: Wang Yi , Xiao Chiwei
Published: August 2023

Laos, the only landlocked country in Mainland Southeast Asia (MSEA), has established over 40 geopolinomical mechanisms with its neighboring countries (including China, Vietnam, Cambodia, Thailand, and Myanmar), leading to significant land-use change (LUC) in the border areas. However, the spatial characteristics and national differences of LUC in the border areas of Laos remain unknown. Through the use of land-use products from 1985 to 2020 and by employing GIS spatial analysis, the results indicate that (1) LUC along the Laos border has led to severe and extensive deforestation, primarily attributed to the rapid expansion of construction land and the consistent growth of cropland. (2) With strengthened border cooperation, differences between LUC in Laos and its neighboring countries have decreased since 1985. (3) Cropland and construction land on the Laos–China and Laos–Thailand borders show obvious bordering characteristics, with increasing land-use homogeneity in near-border areas. In contrast, the Laos–Vietnam, Laos–Cambodia, and Laos–Myanmar borders display the opposite trend. (4) Port areas (e.g., Boten–Mohan port) driven by geopolinomical relations have drastic LUC, but they have huge differences. This study provides a database for quantitative research on the interaction between geopolinomical relations and border LUC to promote border geography, including impact and response.
