Authors: Minozzo Letícia Dutra , Cerri Maria Luisa , Gabiatti Naiana Cristine , Montanher Paula Fernandes , Bittencourt Sydney Eduardo , Anschau Andréia
Published: June 2023

A growing population implies an increasing demand for food. Consequently,
the processing industry related to it generates large amounts of waste. This problem
arose due to the delayed development in establishing effective and advanced waste
management technologies, which must be developed and used to lower the cost of
producing processed foods and minimizing pollution risks. Recent studies on the
valorization of residues in the food chain have focused on obtaining value-added
products such as biofuels, enzymes, bioactive compounds, biodegradable plastics, and
nanoparticles. Regulatory agencies and the food processing industries can work
together to develop new waste management and use processes that are commercially
viable. This chapter presents an introduction to bioremediation and management of
various residues from the food industries (beverages, dairy, fruit, vegetables, oil and
meat), as well as some characteristics, advantages, and limitations of some methods.
New possibilities for using food waste are also described.

Kalium merupakan salah satu unsur hara esensial yang dibutuhkan tanaman untuk pertumbuhan dan perkembangannya. Aplikasi kalium juga dapat meningkatkan ketahanan tanaman terhadap serangan hama. Kegiatan pemupukan merupakan salah satu cara praktis dalam pengendalian hama terpadu (PHT) sebagai komponen budidaya tanaman sehat. Tujuan dilakukannya penelitian ini adalah untuk mempelajari dan mengetahui pengaruh aplikasi pupuk kalium terhadap biologi dan statistik demografi Nezara viridula pada polong kedelai agar diketahui dosis pupuk kalium yang sesuai sehingga tidak menyebabkan tingginya populasi hama N. viridula dalam upaya peningkatan produksi kedelai. Kegiatan penelitian dilaksanakan di Laboratorium Hama Tumbuhan dan rumah kawat Departemen Hama dan Penyakit Tumbuhan, Fakultas Pertanian, Universitas Brawijaya sejak bulan Januari – Juni 2022. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 3 ulangan. Perlakuan yang diberikan yaitu tingkat dosis pupuk KCl yang diberikan pada tanaman kedelai sebagai pakan N. viridula yaitu 0 kg/ha, 25 kg/ha, 50 kg/ha, dan 75 kg/ha. Hasil dari penelitian ini menunjukkan bahwa aplikasi pupuk kalium dapat memengaruhi beberapa variabel pengamatan biologi dan statistik demografi N. viridula. Peningkatan dosis pupuk kalium dapat menekan pertumbuhan dan perkembangan N. viridula yang ditunjukkan dengan rendahnya nilai laju reproduksi kotor (GRR) dan laju pertambahan intrinsik (r) pada perlakuan pupuk kalium dosis tinggi.
Depression and Anxiety among Low and Middle-Income Turkish Women: The Roles of Coping, and Personal and Environmental Resources/Düşük ve Orta Gelirli Türk Kadınlarında Depresyon ve Anksiyete: Baş Etme ve Kişisel ve Çevresel Kaynakların Rolü
Authors: Ulusoy Gökçek Vahide , Tepeli Temiz Zahide
Published: June 2023

Introduction: Psychosocial theory of mental well-being suggests that coping, socioeconomic status, environmental resources such as perceived and received social support, and personal resources such as self-efficacy can be related to psychological well-being. The current study aims to discuss differences in well-being and psychological resources of Turkish women with low and middle-income. It also aims to examine the differences among lower income women’s well-being according to receiving non-governmental organization (NGO) support. Finally, it studies the link between income level, self-efficacy, perceived social support, ways of coping with stress, depression, and anxiety among Turkish women with different income levels. Method: Out of 129 women participated in the study (Mage = 39.12), 60 are with middle-in- come, and 69 are with low-income. Twenty-eight of those with low income receive NGO support. Results: Findings indicates that middle-income women are coping more effectively and have high- er perceived social support, while low-income women significantly report more depressive symptoms. Low-income women with NGO support report more symptoms, perceive less social support, and are coping less effectively than women without NGO support. Hierarchical regression analysis reveals that coping styles, self-efficacy, income level, and perceived social support are associated with depression. Moreover, coping styles and perceived social support are related to anxiety. Conclusion: Personal resources like coping and self-efficacy seem to be the most significant predictors of depression and anxiety. However, poverty is still a serious environmental risk to well-being.

Authors: Turrin Mauro , Fornasiero Lucia , Navarro Antonio
Published: June 2023

We describe the clinical case of a 74-year-old male patient who received the second Comirnaty/Pfizer anti-COVID-19 vaccine dose. After 3 weeks he showed the clinical signs of polymyalgia rheumatica. The history included mild chronic normocytic normochromic anemia and hypogammaglobulinemia, osteoarthritis disease, livedo reticularis, hypercholesterolemia, and arterial hypertension. Despite prolonged treatment with NSAIDs and dexamethasone, the disease evolved into remitting seronegative symmetrical synovitis with pitting edema (RS3PE) syndrome. Neoplastic diseases and associated collagen diseases were excluded. The clinical picture recurred, soon after, the booster dose of the Spikevax/Moderna vaccine. The inflammatory indices were high, the radiographs of the hands were free of erosions, the ultrasound investigations revealed bursitis of the shoulders, knee synovitis, marked subcutaneous edema of the lower limbs, hydrocele, bilateral Baker's cyst in the popliteal cavity, hematoma of a calf. The clinical picture, markedly improved, with oral prednisolone and was stabilized with the association of hydroxychloroquine. The finding of persistent hypomagnesemia was related to chronic intake of esomeprazole. The reports of rheumatological reactions in international databases and the rare cases of RS3PE syndrome following the COVID-19 vaccine described in the literature are considered.

Authors: Zhao Haiping
Published: June 2023

Teachers are the key to education formalization. The study found that the Internet capital of rural teachers in western China is obviously insufficient. Compared with teachers in developed areas, there are significant differences in network facilities, information technology knowledge, online learning and information literacy. The backwardness of network facilities and the lack of information technology knowledge are the important reasons for the lack of Internet capital of rural teachers in western China. Therefore, it is necessary to improve the Internet capital of rural teachers in western China from the aspects of network facilities construction, network knowledge transfer, online learning support and online learning reflection. The proposal of these measures has certain reference value for promoting the improvement of rural teachers’ Internet ability in western China and narrowing the gap with teachers in developed areas.

Analysis of the Impacts of Freight Subsidisation on Transport Mode Selection: An Assessment of the Tasmanian Freight Equalisation Scheme
Authors: Wise Richard J. , Fanam Peter D.
Published: June 2023

The objective of this research is to identify the key selection criteria that form the basis of a shipper’s selection of freight transport mode. The study is undertaken in the context of sea freight. The study is localised to Tasmanian shippers who are, or are potentially, recipients of freight subsidisation through the Tasmanian Freight Equalisation Scheme. Data collected through an internet-based survey is described, and influential mode choice selection criteria are reported with the use of descriptive statistics. The findings indicate that Tasmanian shippers are conscious of cost, service, and cargo characteristics.Median responses indicate that cost, service, and cargo are equally significant in the selection process. The findings indicate that cost and cost flexibility are influential cost-based criteria. The findings also indicate that transit time, service capacity, and service flexibility are influential service-based criteria. Shipment size, cargo weight, and cargo volume are also identified as influential cargo-based criteria.This study provides insight into mode choice selection for Tasmanian shippers. In this function, it may assist existing air and sea carriers operating in the Tasmanian market to evaluate their performance and strategy by providing an analysis of shippers’ transport mode choice process. Tasmanian shippers themselves may benefit from the potential expansion of their existing freight transport mode choice process. New shippers of freight into and out of Tasmania may benefit from the perspectives of existing shippers of freight into and out of Tasmania.

The experiment was carried out in June - September 2022 in medium lowland rice fields (375 m asl) in Central Lombok district, NTB, Indonesia, which was designed using a Randomized Block Design (RCBD) consisting of 14 treatments, namely 9 ideal type red rice lines resulted from Pedigree F5 selection, 1 promising line of red rice from crosses between Kenya and Angka, two parents (the promising line of paddy red rice “GH F2BC4P19-36”, and IPB3S variety), and two control varieties (Situ Patenggang and Inpago Unram 1), repeated 3 times. Observation variables included plant height, days to harvest, number of productive and non-productive tillers, length of panicles, number of filled and unfilled grains per panicle, weight of 100 grains, grain weight per clump and yield potential (tons/ha). The results showed that the red rice line G6 (F5 IPB3S/F2BC4P19-63// Fat/F2BC4P19-63-PD3/17) showed higher grain yield potential (4.79 t/ha) compared to the two parents, namely IPB3S (3.34 t /ha), GH parent (3.27 t/ha), Situ Patenggang (3.92 t/ha) and Inpago Unram 1 (3.35 t/ha). Plant height, number of productive and non-productive tillers per clump, panicle length, numbers of filled and unfilled grains per panicle, grain weight per clump and potential grain yield per hectare were significantly different between genotypes while days to harvest and 100-grain weight were not significantly different.

Abstract: We are currently facing problems with a lack of fuel. That's why we're moving to electric cars. However, people were never ready to love electric cars more than they do now. This is because it costs and there is no place to pay. Although several charging stations are open to the public, it still takes more time to charge a car. In addition, usage is included, and the user cannot get information about electricity usage. Therefore, considering these issues, we can offer smart products that will attract the attention of many businesses. This paper examines the analysis of IoT-based EV charging and monitoring. This project focuses on remote electrical parameters such as electricity, current and frequency and transmits the results of this time and the temperature of the EV charging station over the IOT network using the IOT modem/phone number. Users can send commands based on IoT messages to read remote electronic devices. And the system's bill can also periodically (scheduled) send real-time electricity in the form of IOT.

Abstract: When there is a suspicion of a heart attack, an electrocardiogram (ECG) is a crucial test. It measures the electrical activity of the heart, which is manifested through small electric impulses when the heart beats. The subsequent process of analyzing ECG patterns is time-consuming but vital in determining the likelihood of cardiovascular disease by medical professionals. This project utilizes ECG image data to automate the interpretation of ECG recordings, aiming to assist clinicians in detecting life-threatening Myocardial Infarction. By taking an ECG image as input, the system classifies and attempts to categorize the final result into five classes: Non-Ectopic Beats, Supraventricular Ectopic Beats, Ventricular Ectopic Beats, Fusion Beats, and Unknown Beats.

Abstract: Bearings for sugar mills are known to withstand high load and low speed operations. A temperature rise was detected in the warehouse of a sugar factory, when working in the polluted or contaminated environment of the sugar industry. Therefore, an experiment was conducted on brass (CuZn) plain bearings when lubricated with water with different flow rates. In this study, the rise in temperature of a plain bearing in a sugar factory was analyzed. By simulating the operating conditions in a sugar mill the causes for rise in temperature in the bearing were identified and commissioning in a plain bearing test rig that takes into account the combination of operating conditions (self-load, speed, dirt, lubricants, etc). Insufficient supply of internal lubricant can lead to plain bearing failure. This affects the production costs of the industry and can also endanger human lives. The brass journal bearing gives the best performance under the Q3 flow of water and also have lesser rise in temperature.

Learner autonomy is the main solution for overcoming learning loss in the limited face-to-face policy (PTM) that was implemented in Indonesia in early 2022. This research is based on the phenomenon of the decreasing quality of learning Arabic due to the pandemic. A qualitative research approach with the type of case studies used in this research is used to reveal the decline in learning and independent learning at tertiary institutions in Jambi Province. A case study approach is used in this study. The main findings and results are described by uncovering a case of learning loss in limited face-to-face policies in Jambi Province. This research addresses two main focuses: First, the phenomenon of learning loss is caused by several factors, such as adaptation to hybrid learning, limited internet access, minimal learning platform services, and technological stuttering. Finally, learner autonomy on limited face-to-face learning (PTM) policies in Jambi implementation of independent learners By the Autonomy Learning Scale (ALS), fulfilling the seven aspects of self-learning implementation with the highest (good enough) score on the three categories of self-awareness indicators (6.5 score), self-effort (6.5 and extensive autonomous activities (6.7 score) achieves a score of 6.7. And the low category on the aspect of self-confidence with a score of 2.5 and motivation, which only gets a score of 0.5.

Published: June 2023

Each level of age in humans will have certain developments. Likewise, at the age level of children, there will be abilities that will increase as they get older. Children aged 4-5 years have started to have the ability to apply self-help skills to meet their basic needs such as food, clothing, grooming, personal hygiene and independence in going to the toilet. The client is the youngest daughter of 2 siblings. Children with global developmental delay problems will have difficulties in self-care. He is 4 years old. The client lives with his parents, brother and grandmother. Until now the client has not been able to behave independently of his daily activities such as going to the toilet himself. The purpose of this case study is to improve the subject's ability to be independent with toilet training. The assessments used were observation, interviews and VSMS (Vineland Social Maturity Scale). The intervention given to improve the toilet training ability of the client was the provision of positive reinforcement. The results of the intervention that had been given to the client showed significant changes, namely a decrease in the intensity of bed wetting and an increase in the ability to take off/put on pants, wash, flush and wash hands independently. However, clients still need family assistance in going to the toilet or must remain with parental assistance and initiative.
 
Setiap tingkatan usia pada manusia akan memiliki perkembangan tertentu. Demikian pula pada tingkat usia anak-anak, akan ada kemampuan yang akan meningkat seiring bertambahnya usia. Anak usia 4-5 tahun sudah mulai memiliki kemampuan untuk menerapkan keterampilan menolong diri sendiri untuk memenuhi kebutuhan dasarnya seperti makanan, pakaian, dandan, kebersihan diri dan kemandirian ke toilet. Klien adalah putri bungsu dari 2 bersaudara. Anak dengan masalah keterlambatan perkembangan global akan mengalami kesulitan dalam perawatan diri. Klien berusia 4 tahun tinggal bersama orang tua, kakak dan neneknya. Sampai saat ini klien belum dapat berperilaku mandiri dalam aktivitas kesehariannya seperti ke toilet sendiri. Tujuan dari studi kasus ini adalah untuk meningkatkan kemampuan klien untuk mandiri dengan toilet training. Penilaian yang digunakan adalah observasi, wawancara dan VSMS (Vineland Social Maturity Scale). Intervensi yang diberikan untuk meningkatkan kemampuan toilet training klien adalah pemberian penguatan positif. Hasil intervensi yang telah diberikan pada klien menunjukkan perubahan yang signifikan yaitu penurunan intensitas mengompol dan peningkatan kemampuan melepas/memakai celana, mencuci, menyiram dan mencuci tangan secara mandiri. Namun, klien tetap membutuhkan pendampingan keluarga dalam ke toilet atau harus tetap dengan pendampingan dan inisiatif orang tua.
