Music, Language, and Autism: Neurological Insights for Enhanced Learning
Authors: Luo Emanuel , Pan William , Fan Xiujun
Published: September 2023

This comprehensive review thoroughly explores the intricate relationship between music and language, encompassing their historical, cognitive, and neural dimensions. It draws evidence from ancient Chinese civilizations dating back to 4500 BC to analyze the coexistence and parallel evolution of music and language for the first time. Comparative studies illuminate the shared and distinctive aspects of pitch, rhythm, and syntax inherent to music and language. The examination extends to the diverse impact of music, including second language acquisition, phonological awareness, pitch processing, memory, and cognitive skills. This influence is also observed among individuals with Autism Spectrum Disorder. The paper further examines the intricate neural connections, neural overlapping, networks, structural processing, bidirectional relationships, cross-modal transfer effects, and brain plasticity that underpin music and language. It reviews music interventions for enhancing language and cognitive abilities, particularly in the context of autism spectrum disorders. However, the precise role of music and its intricate neural mechanisms in shaping language-related outcomes within Autism spectrum disorder groups remains incompletely understood. Further interdisciplinary research integrating disciplines like neuroscience, psychology, sociology, and related fields is imperative to deepen our comprehension and unlock the precise neural mechanisms and interventions that can foster enhanced language and cognitive development in individuals with autism.

Tea plantation biomass wastes, such as tea plantation pruning, shade trees, and woody weeds have not been utilized. The waste can be used as renewable energy in the form of wood pellets. The problem is the feasibility of biomass waste to be used as material for making wood pellets as energy. This paper aims to analyze the potential of tea plantation biomass waste as wood pellet material to meet energy needs. The research was conducted in a tea plantation owned by the Tea and Kina Research Center (PPTK). Quantification of biomass waste potential per unit area was conducted in the plantation using direct measurement method. Proximate analysis of each wood pellet variant of biomass waste was conducted to match the quality of Indonesian Wood Pellet Standard. The biomass waste potential in PPTK is 14,281 tons per year which can produce 8,186 tons of wood pellets per year. This potential can meet the needs of wood pellet consumption from the tea production process at PPTK which is around 1.8 tons / day for the tea processing process of 13 tons/day. Based on proximate analysis, the wood pellets produced have a calorific value of 4425 cal/gram, density of 1.35 grams/cm3, fixed carbon content of 85.2%, and volatile matter of 3.72%. These results confirm that the wood pellets comply with the National Wood Pellet Standard (SNI 8021:2014). This can be a model for the application of the Green Circular Economy concept in the plantation sector. Keywords:   Biomass pellets; Green circular economy; Renewable energy; Tea plantation waste; Wood pellets

Published: September 2023

Several citrus species when physiologically ripe are still yellow-green in color, one of which is the Tangerine RGL (Rimau Gerga Lebong) grown in the city of Pagar Alam, South Sumatra. To improve the physical quality of tangerines, RGL can be applied with degreening technology and low-temperature storage. This study aims to examine the effect of degreening and low-temperature storage on physicochemical changes and to determine the optimum method of degreening and low-temperature storage on citrus quality. This study used a completely randomized 2-factor design. The first factor is degreening with 4 levels (0 ppm, 250 ppm, 500 ppm, 750 ppm), and the second factor is storage temperature with 3 temperature levels (10ºC, 20ºC, and room temperature). The results showed degreening increased the CCI value by 3.48-3.82, changing the skin color to uniformly yellow and did not affect the internal quality of the fruit. Treatment with a temperature of 10oC extended the shelf life of the fruit up to 29 days. The combination of 250 ppm ethepon and 10oC effectively suppressed weight loss to maintain the quality of RGL tangerines. Keywords: Degreening, Low-temperature storage, RGL tangerines, Shelf life, Uniform color

Published: September 2023

Rice is one of the staple foods produced in Indonesia. One of the postharvest processes experienced by rice is storage. During the storage process, rice changes cooking quality, physical and physicochemical qualities. This research aims to analyze changes in cooking, physical and physicochemical qualities of Indonesian rice varieties. The rice varieties used, namely Sintanur, Ciherang, and IR 42 were stored at storage room temperatures of 30˚C, 20˚C, and 10˚C. Rice taken from farmers was stored for 4 months and changes were measured for parameters of water content, color (chroma, hue, whiteness), amylose, elongation ratio, gel consistency, alkali spreading value (ASV), water absorption, and texture profile (packability, hardness, cohesiveness, extrudability, chewiness). The results showed that the lowest water content was at sintanur which was stored at 10 ˚C, namely 3.09% wb, elongation, and ASV increased with the highest final value at sintanur 30 ˚C, namely 2.07 and 4.45, the consistency of the gel decreased in the first week then stable in the following week, on the other hand, water absorption increased at the beginning of storage and did not change much until the end of storage. Statistical tests showed that there was an interaction between time*variety*temperature on the parameters of water content, whiteness, elongation ratio, water absorption, amylose, and chewiness. Based on the research results, it was found that several parameters did not interact with temperature, namely hue, packability, hardness, and extrudability. Keywords: Amylose content, Cooking quality of rice, Physical quality of rice, Rice storage

Penelitian ini memiliki tujuan untuk mengetahui pengaruh fraud hexagon theory terhadap kecurangan laporan keuangan. Variabel yang digunakan meliputi tekanan eksternal, target keuangan, kemampuan, kolusi, nature of industry, rasionalisasi, dan arogansi. Populasi penelitian ini adalah perusahaan sektor kesehatan di BEI selama tahun 2016–2019. Teknik pengambilan sampel menggunakan purposive sampling dan diperoleh 13 perusahaan dengan 52 unit analisis. Pengujian data dilakukan menggunakan metode regresi linier berganda. Hasil penelitian menunjukkan bahwa variabel tekanan eksternal, target keuangan, kemampuan, kolusi, rasionalisasi, dan arogansi tidak mampu memengaruhi kecurangan laporan keuangan. Namun, variabel nature of industry berpengaruh negatif terhadap kecurangan laporan keuangan. Nature of industry yang direfleksikan dengan rasio perubahan piutang memberikan hasil bahwa kenaikan piutang yang terjadi sebagai akibat dari kenaikan penjualan tidak membuat perusahaan untuk melakukan kecurangan laporan keuangan. Sebaliknya, kenaikan piutang tersebut dapat dijadikan peluang untuk menarik investor dan bersaing dengan kompetitor. Kenaikan piutang tidak menyebabkan jumlah kas menjadi berkurang dan masih dianggap cukup untuk operasional perusahaan, sehingga risiko kecurangan semakin rendah.
Lelang Aset Digital melalui Non-Fungible Token dalam Perspektif Hukum Ekonomi Syariah
Authors: Aini Sifa Barokah
Published: September 2023

Lelang melalui Non-fungible Token (NFT) merupakan fenomena yang cukup baru yang terjadi di era digital, sehingga perlu dicarikan standar hukumnya. Dalam lelang melalui Non-fungible Token pembeli hanya melakukan penawaran melalui website dan dikenakan biaya yang cukup tinggi untuk setiap penawarannya. Sedangkan pembayarannya menggunakan uang kripto (cryptocurrency). Kajian ini bersifat kualitatif dengan pendekatan normatif dalam menjawab permasalahan bagaimana hakikat lelang aset digital melalui NFT dan bagaimana perspektif Hukum Ekonomi Syariah. Kajian ini berkesimpulan bahwa jual beli benda digital sebenarnya tidaklah dilarang, termasuk jual beli NFT dengan teknologi blockchain yang kecanggihannya dapat menyimpan data tanpa bisa dihapus, sehingga dapat meminimalisir terjadinya pemalsuan. Namun karena undang-undang di Indonesia telah menetapkan rupiah sebagai alat pembayaran yang sah di negara Indonesia, maka jual beli aset digital dalam bentuk NFT menjadi tidak sah karena alat pembeliannya menggunakan cryptocurrency. Selain itu, lelang aset digital melalui NFT untuk saat ini juga dilarang bagi umat Islam karena Majelis Ulama Indonesia menetapkan hukum haram terkait penggunaan cryptocurrency disebabkan belum adanya underlying atau otoritas yang mengaturnya, sehingga mengandung unsur gharar, dharar dan qimar, yang dikhawatirkan tidak membawa maslahah bagi pengguna cryptocurrency sehingga diharamkan.

beteg önrendelkezéshez való jogának törvényi tartalma és megjelenése a bírói gyakorlatban
Authors: Zákány Judit
Published: September 2023

A tanulmány célja a beteg önrendelkezéshez való jogának vizsgálata, jogértelmezési kérdéseinek bemutatása. Az önrendelkezési jog kiemelten fontos betegjog, mivel a tájékoztatáshoz való jog mellett együttesen biztosítja, hogy a páciens ne egy információhiányban szenvedő, kiszolgáltatott szereplője legyen az egészségügyi ellátásnak, aki helyett más hoz döntést, hanem egy tájékozott fél, aki a kapott információk birtokában képes saját érdekének és értékrendjének megfelelően dönteni a kezelésével kapcsolatban.
A vizsgálat középpontjában az önrendelkezési jog legszűkebb értelmezése, azaz a beavatkozásokba történő beleegyezés, ennek korlátai, illetve a jog helyettes döntéshozók általi gyakorlása áll. A jog törvényi tartalmán és értelmezésén túl fontos, hogy az utóbbi néhány év ítélkezési gyakorlatából is említsünk példákat, és az ezekben szereplő jelentősebb megállapításokat megjelenítsük. Az önrendelkezési jog vizsgálata aktuális és indokolt, tekintve, hogy az ezzel kapcsolatos jogviták, kárigények napjainkban is folyamatosan jelen vannak, így a jogértelmezés is fejlődést mutat ezen a területen.

El monitoreo de la frecuencia respiratoria es relevante para predecir oportunamente eventos adversos, y tradicionalmente se realiza con dispositivos especializados que son difícilmente trasladables fuera de ambientes clínicos y de investigación. En este trabajo se exploran algoritmos de procesamiento de imágenes y señales para estimar la frecuencia respiratoria instantánea (FRI) a lo largo de diversas maniobras respiratorias en estado de reposo, mediante la estimación óptica remota (EOR). La señal de respiración fue extraída de una secuencia de video obtenida de un smartphone y comparada con la señal de respiración obtenida con un termistor conectado al Biopac. Se encontró que ambas señales están altamente correlacionadas linealmente (ρ>0.8) para la mayoría de las maniobras. En cuanto a la FRI, el análisis de Bland-Altaman reveló un sesgo de -0.05 rpm y límites de concordancia entre -4.25 y 4.15 rpm entre la estimación con la EOR y el termistor.

Nghiên cứu này kiểm định tác động của việc thực hiện trách nhiệm xã hội đến tính thanh khoản cổ phiếu của công ty. Sử dụng mô hình hồi quy dữ liệu bảng có kiểm soát tác động cố định của công ty, ngành và năm áp dụng bộ dữ liệu gồm 159 công ty đến từ các thị trường mới nổi trong giai đoạn 2002 -2016, nghiên cứu chỉ ra rằng các công ty hoạt động trên các thị trường mới nổi có mức độ thực hiện trách nhiệm xã hội càng cao sẽ có tính thanh khoản cổ phiếu càng thấp. Quan hệ nghịch chiều này đến từ cả ba khía cạnh bao gồm chỉ số môi trường, xã hội, và quản trị. Kết quả này phù hợp với giả thuyết đặt ra rằng ở các thị trường mới nổi, tình trạng thao túng thông tin, môi trường thể chế yếu kém, và mức độ bảo vệ nhà đầu tư thấp làm tăng thông tin bất đối xứng và giảm tính thanh khoản cổ phiếu của các công ty. Đặc biệt, mối quan hệ nghịch chiều này bị suy yếu với các công ty được kiểm toán bởi các công ty kiểm toán uy tín hàng đầu hoặc các công ty hoạt động ở các môi trường thể chế mạnh.

Application of living mulch in rows of the apple trees on several rootstocks – long-term evaluation
Authors: Licznar-Małańczuk Maria , Kwiecińska Iwona
Published: September 2023

The long-term influence of several living mulches on apple tree growth, nutrient status, yield, and fruit quality concerning the year of cover crop sowing in tree rows was evaluated in the Lower Silesia region in the southwestern part of Poland. The estimation was conducted in six apple tree ‘Ligol’ populations differentiated by the rootstock: M.26, M.9, P 60, P 2, P 16, and P 22. In experiment no. 1, one-year-old nursery stock was planted, and perennial living mulches were sown: colonial bent grass (Agrostis vulgaris With.) and white clover (Trifolium repens L.) in the same year and blue fescue (Festuca ovina L.) in the following year. In experiment no. 2, which involved two-year-old stock, the sowing of blue fescue was delayed until the second, third, fourth, and fifth years following orchard planting.
The presence of the cover crop significantly affected young tree growth when one-year-old trees were planted. The sowing of the living mulch in the first or the second year after tree planting led to a significant reduction in the cumulative yield obtained from the young trees. The living mulch improved the red coloration of the fruit skin in the young orchard, but it caused a reduction in the mean fruit weight and size. However, it also contributed to decreased nitrogen concentration in the leaves of the apple trees, and the tree tolerance to living mulch increased as the orchard aged. A choice of semidwarf rootstock, postponed sowing of cover crop, and high-quality nursery stock were recognized as the most important factors for fostering apple tree tolerance to living mulches in tree rows.
Effects of different irrigation levels and varying doses of silicon applications on yield and some physiological parameters in lettuce cultivation
Authors: Çelik Yusuf
Published: September 2023

The study was repeated for two years to reduce the effects of water scarcity and drought stress in lettuce cultivation. The irrigation problem was created by applying 25% (I25), 50% (I50), 75% (I75) and 100% (I100) of the evaporation amounts formed in the class-A evaporation vessel. Si0 (0 kg ha–1), Si40 (40 kg ha–1), Si80 (80 kg ha–1) and Si120 (120 kg ha–1) silicon fertilisation was applied at four different doses. Head length, head diameter, head weight, root length, and leaf fresh and dry weight were measured in harvested plants. According to the data of 2020–2021, the best results in the effect of different doses of Si applications on plant head height, head diameter, head weight and root length at different irrigation levels were recorded from I75 × Si80, I75 × Si120, I100 × Si80, I100 × Si120 applications with the same severity level. While the Si40 dose gave good results at I75 and I100 irrigation levels, its effect decreased at I25 and I50 irrigation levels. At different irrigation levels where different doses of silicon were applied, I25 irrigation had the lowest leaf chlorophyll and relative moisture content and the most severe membrane damage, while I50 irrigation had a moderate effect. Leaf chlorophyll and moisture content increased, and membrane damage decreased in I75 × 80 kg ha–1 Si, I75 × 120 kg ha–1 Si, I100 × 80 kg ha–1 Si and I100 × 120 kg ha–1 Si applications. As a result, when the effects of the applications covering two years on plant growth and yield were evaluated, the most successful irrigation levels were determined as I75, I100, and the most successful silicon doses; were determined as 80 kg ha–1 and 120 kg ha–1.

Geriatric horses have a high prevalence of dental disease, which is a culmination of age-related dental changes and dental disease throughout the life of the horse that may have long-term consequences. Wear abnormalities, diastemata with periodontal disease, pulpitis and endodontic disease, infundibular caries, and equine odontoclastic tooth resorption and hypercementosis become more prevalent with age. Recognition of age-related dental disease at an early stage can help to treat and possibly preserve teeth for longer. With a natural decrease in masticatory efficiency, it is even more important to preserve teeth where possible and prevent any painful dental disease. Regular routine dental examination and maintenance will help to prevent many dental conditions such as wear disorders and possibly secondary diastemata. Successful treatment and management of most dental diseases are possible even in older patients and will ensure that we are able to maintain a high standard of welfare as horses age.
"No Wonder That on This Spot God Spoke to Us": Intersection of Anglican Tourist-Pilgrims and Archaeology in British Mandate Palestine
Authors: Emmott Chloë
Published: September 2023

For British Anglican tourists, archaeological tourism in Palestine marked an expansion of a broader British cultural and religious relationship to Palestine as a land made familiar by a childhood of bible stories and nativity scenes, and one which played a role in the biblification of Palestine and the appropriation of its past to validate and strengthen a connection to Britain and the Mandate. Archaeology offered a direct link to the materiality of the biblical past, experienced via a “kairotic moment” in which the past meets the present. By examining reports of British travelers to Palestine, this article considers how materially embodied religious experiences not only drove tourist movement to Palestine but also functioned as a keystone in Britain’s relationship with Palestine during the Mandate period. Behind this growth in archeological tourism, however, is a story of tension, most notably between Mandate Palestine’s first director of antiquities, John Garstang, and the Mandate and Westminster governments. From his optimism in a report on the future of archaeology in Palestine in 1919 to his bitter resignation in 1926, Garstang’s story represents the Mandate’s failures with regard to archaeology. These tensions and Garstang’s unease foreshadowed the development of archaeology as a tool of settler colonialism in occupied Palestine today.

Authors: Wang Yangping , Yang Yong , Shu Ziqin , Song Huapei
Published: September 2023

Background. Severe burns can readily induce gastric and duodenal mucosal erosions and superficial ulcers. In severe cases, haemorrhage or perforation of peptic ulcers might occur, threatening the lives of patients. At present, gastrointestinal haemorrhage after burns is treated mainly with drugs and gastrointestinal endoscopy. However, multidisciplinary treatment of gastroscopy combined with vascular embolization is rare.
Case. A boy aged 3 years and 4 months was admitted to the hospital, scalded by boiling water on multiple parts of the body. On the 8th day after the injury, the patient continuously produced a large amount of tarry black stool, and the faecal occult blood test was positive. Haemostatic drug treatment was ineffective, and severe shock and disseminated intravascular coagulation (DIC) occurred. Under the guidance of a multidisciplinary team (MDT), a gastroscopy examination was performed and showed bleeding from a duodenal bulb ulcer. Due to a small intestinal lumen and thin intestinal wall, bleeding could not be controlled by gastroscopy. However, the bleeding point was clarified by gastroscopy and then gastroduodenal artery embolization was performed efficiently. No active gastrointestinal bleeding was observed after the surgery. The patient was followed for 6 months after discharge, and no gastrointestinal haemorrhage recurred.
Conclusions. This is a rare case of acute massive upper gastrointestinal bleeding secondary to post-burn stress in paediatric patients. For paediatric patients who cannot be treated by endoscopy, transcatheter embolization may be safer and more effective for achieving haemostasis. Through the collaboration of the MDT, gastroscopy combined with interventional embolization was performed, which successfully stopped the massive bleeding and saved the child`s life, making it worthy of clinical reference.

Background. We aimed to analyze the levels and associations of SH2 domain-containing protein 1A (SH2D1A), immunoglobulins and T lymphocyte (TL) subsets in children with Epstein-Barr virus (EBV) infections.
Methods. Sixty children with EBV infections admitted from January 2019 to January 2022 were selected, including 29 cases of infectious mononucleosis (IM group) and 31 cases of chronic active EBV infections (CAEBV group). Another 42 healthy children undergoing physical examination in the same period were selected as a control group. Their changes in SH2D1A, immunoglobulins and TL subsets (CD3+, CD4+ and CD8+) were compared.
Results. The levels of CD3+, CD4+ and CD8+ in the IM group were higher than those of the control group (P < 0.05), while they were lower in the CAEBV group than those of the control and IM groups (P < 0.05). The levels of SH2D1A, signaling lymphocyte activation molecule (SLAM) and SLAM-associated protein (SAP) were significantly higher in the IM group than those in the control and CAEBV groups (P < 0.05). The CAEBV group had decreased protein expressions of SLAM and SAP compared with those of the IM group. SH2D1A was positively correlated with immunoglobulin A, immunoglobulin G and TL subsets (CD3+, CD4+ and CD8+) (P < 0.05).
Conclusions. Detecting SH2D1A, immunoglobulins and TLs contributes to the diagnosis and differentiation of IM and CAEBV.

Background. Anemia is a common nutritional problem in children, especially those under five. Lactoferrin (Lf) as a supplement in treating iron deficiency anemia (IDA) has been studied, but its results in children have not been reviewed. This review aims to evaluate the effect of lactoferrin on children with IDA.
Methods. PubMed, ProQuest, EBSCO and Ovid databases were searched using a variation of keywords: lactoferrin, anemia, and children. The literature selected must be clinical trial-based in design. The years of the studies published were limited to 2012 and 2022.
Results. Eleven studies were included in the final systematic review, consisting of 10 randomized controlled trials (RCTs) and 1 non-randomized trial. Serum ferritin (SF) and hemoglobin (Hb) were found to be increased in groups treated with Lf or a combination of Lf and elemental iron compared to iron only or placebo supplementation. Adverse events such as constipation, vomiting, anorexia, and abdominal pain were found; particularly, a significant decrease in constipation is seen in Lf-treated groups.
Conclusions. This study supports Lf as a superior treatment for IDA in children regarding the improvement in hematological and iron indices and fewer adverse effects.

Published: September 2023

Background. Pneumatosis cystoides intestinalis (PI) is a rare but important condition in which widespread air sacs are found in the submucosa, and subserosa of the bowel wall. Although it has several etiologies, children receiving chemotherapy are at risk for PI. Preferred imaging tools for the diagnosis are abdominal direct radiography and computed tomography. In patients with PI, rupture of intramural air sacs is the source of benign pneumoperitoneum, causing free air without true intestinal perforation. Intestinal perforation or obstruction are indications for surgical intervention.
Case. Here, we present a 4-year-old patient diagnosed with acute myeloblastic leukemia (AML), who underwent allogeneic hematopoietic stem cell transplantation (HSCT) from a matched sibling donor (MSD) and developed PI after HSCT. The patient was consulted to the pediatric surgery department, and her oral feeding was stopped. Broad spectrum antibiotics (teicoplanin, metronidazol and vancomycin) were initiated. Her fever increased during the 24-hour monitoring, there was no stool passage, CRP ( > 25 mg/dL, normal value < 1 mg/dL) and abdominal distension increased and there was prolonged neutropenia and radiologic investigations could not rule out intestinal perforation, so the patient underwent exploratory laparotomy. No intestinal perforation was found. There was no sign in the intestinal wall and numerous gas-filled cysts of various sizes.
Conclusions. PI is an uncommon complication, and direct radiography/computed tomography scans are very helpful in making the diagnosis in suspicious cases. PI, should be kept in mind, especially in transplanted or relapsed leukemia patients receiving intensive chemotherapy.

Published: September 2023

Immune thrombocytopenia is a relatively common bleeding disorder characterized by isolated destruction of platelets by autoantibodies, with a typically acute onset, benign course and self-limiting in most cases. The aim of this report is to present a rare case of Primary Immune Thrombocytopenia (ITP) with palpable purpura, an uncommon manifestation in this disease and little described in the literature. This is a 12-year-old female adolescent who presented with palpable purpura, ecchymosis and oral cavity bleeding associated with thrombocytopenia and anemia. Initial investigation excluded autoimmune diseases, vasculitis, lymphoproliferative diseases and coagulation disorders, in addition to the myelogram showing typical findings of ITP: hypercellular bone marrow with megakaryocytic hyperplasia and decreased thrombocytogenesis. Due to the diversity of clinical presentation and the possibility of atypical manifestations, the diagnosis is often challenging, as in the case of this patient in which the main finding on physical examination was the presence of palpable purpura.

Iron deficiency anemia is defined as a hemoglobin concentration less than a second standard deviation from the distribution mean for a population of the same sex and age. It is the last event in a progression of negative iron balance, with the stages: negative balance, iron deficiency, and iron deficiency anemia. It is the most common hematologic alteration in the world, especially in developing countries. The main source of iron in the body comes from the red blood cell recycling system, while a smaller portion comes from the diet. Despite this, nutritional deficiency is the main etiology of iron deficiency anemia and iron deficiency in childhood. Iron is essential for several physiological functions and its deficiency, especially in childhood, can compromise mental and physical development. Clinical manifestations usually become detectable in severe deficiency. For this reason, the early diagnosis of iron deficiency is through laboratory tests. It should be performed through screening at 12 months of life. Treatment should be started promptly after diagnosis. Diet is of little value in correcting iron owing to the low bioavailability of iron in most foods. However, preparations containing iron are easily absorbed by the body. Given the severity of this condition, treatment should be monitored using laboratory parameters. This study aims to develop a protocol for screening and monitoring the treatment of iron deficiency anemia to systematize and organize care, bringing better results for the childs development.
