Authors: Nadzirah Rufiani , Saputra Yoga Rezky , Indarto Indarto
Published: April 2023

Nowadays, vegetation classification can be used to find out the latest information about the characteristics and distribution of vegetation in an area. However, a conservative process to differentiate vegetation was ineffective. Some of those limitations are poor accessibility that does work less safety, time-consuming, and needs a lot of human resources. On the other hand, remote sensing offers solutions that cannot be done by the simple method, such as how to take the data, time-consuming are less, and human resource needs are less as well. The purpose of this study was to classify, measured the area of each vegetation, and compared the effectiveness of the unsupervised used K-Means algorithm and supervised used Object Base Image Analysis algorithm methods vegetation classification. For accuracy calculation with confusion matrix, the classification results of the two methods were compared with the manual digitization method. Data was taken using drones in the area of the Curah Manis Sempolan Nature Reserve 1. Classification of vegetation consists of 5 vegetation types, which was apak, bush, pine, bendo, and dadap. The total area of the study area was 1.633 ha, and area vegetation of each classification was apak 0.224 ha; bush 0.748 ha; pine 0.394 ha; bendo 0.222 ha; and dadap 0.045 ha. The results of the calculation of accuracy showed that the unsupervised method had a value for overall accuracy of 80% and kappa accuracy of 73.58%. Then, in the supervised for overall accuracy is 68% and kappa accuracy of 58.72%.

Penambahan Serbuk Kelopak Bunga Rosela (Hibiscus sabdariffa L.) untuk Meningkatkan Aktivitas Antioksidan pada Tempe Kedelai
Authors: Sitanggang Nopiana Elia Putri , Dewi Lusiawati
Published: April 2023

Tempeh is a traditional food product made from soybeans through a fermentation process by tempeh mold (Rhizopus sp.). This food product besides having high nutritional value also contains antioxidant compounds which are very good for consumption but with a relatively low IC50 value. This study used rosella flower calyx (Hibiscus sabdariffa L.) which are believed to have a high enough antioxidant content so they are effective in increasing the antioxidant content in tempeh. Furthermore, the addition of rosella calyx powder will give tempeh an attractive taste, aroma, and color. The objective of this research was to determine the effect of rosella calyx powder addition on tempeh making with various concentrations, i.e. 0% (P0), 0.5% (P2), 1% (P3), 1.5% (P4), and 2% (P5). The antioxidant activity using the DPPH method, the organoleptic properties based on the preference level (hedonic) using a questionnaire, and the water content of tempeh based on the principle of gravimetry method were also tested. The result showed that the IC50 value of 2% concentration of rosella calyx powder addition (P5) was 1596.9 ppm. IC50 of the P5 treatment was the highest antioxidant activity power category compared the other treatment, even though it was still relatively low in antioxidant activity. Then on the organoleptic test, the results showed that the addition of rosella flower calyx powder was able to affect the taste, color, and aroma of tempeh and has no effect on the water content of tempeh.

Karakteristik Fisikokimia Tepung Sorgum (Sorghum bicolor L.) Varietas Lokal Merah dengan Fermentasi Spontan
Authors: Yusra Syarifah , Putri Elisa
Published: April 2023

Modification of flour was carried out to improve the functional properties of starch and to expand the use of starch in food products. Local red varieties of sorghum (Sorghum bicolor L.) were modified by spontaneous fermentation to increase protein digestibility and carbohydrate digestibility. In this study, 2 stages were carried out, i.e. natural sorghum flour (TSA), and spontaneously fermented sorghum flour (TSFS) with 3 levels of fermentation times (12, 48, and 72 hours TSFS). The purpose of this study was to determine the physicochemical characteristics of local red sorghum flour using the spontaneous fermentation method. The resulting product was observed for amylose content, tannin content, color, and amylograph profile with a rapid visco analyzer (RVA). The results showed that the fermentation conditions with 72 hours of TSFS increased the highest amylose content (6.43% wb) followed by the greatest change in the amylograph profile of the peak viscosity (2621 cP) compared to the 12 hours of TSFS and 48 hours of TFSF. This correlated positively with a significant decrease in tannin content in the 72-hour TSFS treatment (7.53 mg as.tannat/g). The tannin content lost by this method reached 60% of sorghum flour without treatment (16.69 mg as.tannat/g). However, in the analysis of the brightness level of sorghum flour, it was shown that the brightest color was obtained in the 48 h TSFS treatment. Modification of sorghum flour by spontaneous fermentation (using aquades immersion) can increase starch degradation and effectively improve the physicochemical properties of local varieties of red sorghum flour.

An Empirial Study on Vietnam’s Trade Faclilitation in the Digital Economy
Authors:   IAGBT, Thanh Huong Vu , Thi Thuy Hanh Lam , Nguyen Ha Phuong
Published: April 2023

Purpose - Vietnam is among the fastest growing digital economies in the Southeast Asian region, and has made enormous efforts to adopt digital measures to facilitate trade. The paper aims to assess Vietnam’s performance of digital trade facilitation and estimate the impact of digital trade facilitation on Vietnam’s exports to the Association of Southeast Asian Nations (ASEAN).
Design/Methodology/Approach - Vietnam’s implementation of digital trade facilitation is assessed through a constructed framework based on two groups of indicators, including Information Availability and Formalities Automation extracted from the OECD Trade Facilitation database. Further, a gravity model was adopted to estimate the impact of digital trade facilitation on Vietnam’s exports.
Findings - The results show that Vietnam performs a slightly better than the average level of ASEAN countries. However, Vietnam’s implementation of digital trade facilitation tends to be ỉmproving at a slower rate than other ASEAN countries’ implementations, as well as the country’s overall implementation of other trade facilitation. The paper is among leading studies to quantify the impact of digital trade facilitation on Vietnam’s exports to ASEAN countries, and finds that if Vietnam and ASEAN countries increase trade facilitation through Information Availability measures by 1%, Vietnam’s exports will increase more than proportionately by 1.29% and 1.01%, respectively. Meanwhile, the digitalization of trade formalities so far has had no effect on Vietnam’s exports to this region.
Research Implications - Vietnam should place priority on enhancing automation in trade-related administrative procedures, especially in customs procedures. Furthermore, it should pay more attention to promote the electronic publication of trade-related information, enhance the transparency of government policymaking, and increase the quality of enquiry points.

Determination of the risk group for professional burnout for teachers of Higher education
Authors:   Smolensk State University, Silchenkova Svetlana V. , Tsareva Valentina M.
Published: April 2023

The level of professional emotional burnout of teachers of higher education was studied to identify those most at risk. The technique of K. Maslach and S. Jackson was used, as well as an integral indicator — a systemic index of burnout syndrome. Statistical methods for processing the observation results were used. The sample consisted of 60 people (teachers from two universities in Smolensk: Smolensk State University — 30 people and Smolensk State Medical University — 30 people). The samples of the two universities did not differ significantly in terms of age, length of service, and gender. The study period is April–July 2022. As a result of the study, it was found that, in general, the level of professional burnout of city teachers is average. According to the scales of professional burnout (emotional exhaustion, depersonalization, reduction of personal achievements), there are some differences between universities. So the level of depersonalization of the teaching staff of the medical university is low. A correlation analysis of the levels of professional burnout scales based on the signs: gender, age and length of service were carried out. It has been established that the level of emotional exhaustion of higher school teachers depends on gender: men are more likely to have high and medium levels compared to women. Models for determining risk groups for professional burnout have been developed. The risk of professional burnout according to the depersonalization scale is characteristic of men under the age of 50 and less than 10 years of work experience. This category of faculty is recommended to be allocated to the risk group of professional burnout in order to carry out further measures to prevent and reduce it.

The modern global world assumed that the major religions would eventually remain — Christianity, Islam, Buddhism, so it is surprising that today there is a return of some long-gone mytho-religious beliefs — a kind of renaissance of beliefs such as animism, shamanism and a special form like magic. All those phenomena did not disappear, but existed quite separately, as a kind of archaism. More and more people are interested in these phenomena as they try to find answers to their concerns through them. Therefore, it is necessary to scientifically consider what they are and what benefit or harm they can bring. An ancient belief like Tenirism is being revived on the territory of Kazakhstan and Kyrgyzstan in the form of religion, which claims a dominant position in the minds of nomads. This fact of course causes rejection among Muslims, who are the overwhelming majority among the local population and provokes not only discontent but also violent protest. Therefore, it is necessary to study these phenomena not only in the scientific community, but also at the governmental level. This study analyses the phenomenon of the influence of mytho-religious beliefs on the stabilisation of anxiety in people.

A guerra está sobre nós: mudanças sociais e política na pintura mural de Bonampak e Chichén Itzá
Authors:   Universidade Estadual de Campinas, Pacheco Fernanda  Grecco
Published: April 2023

Este artigo tem por objetivo apresentar uma discussão de mudanças sociais ocorridas na área maia e na Mesoamérica por volta do século X d.C. a partir da análise de duas manifestações artísticas de duas diferentes cidades. Os murais encontrados na cidade de Bonampak, localizada no sul do atual México, no Estado de Chiapas, e os murais do Templo dos Jaguares de Chichén Itzá, localizada na Península de Iucatã. As duas cidades floresceram em temporalidades e espacialidades diferentes. Bonampak foi uma cidade localizada próximo ao rio Usumacinta, importante rota de comércio e transporte no período pré-hispânico, com um período de esplendor entre 650 e 800 d.C., no qual exerceu um importante papel estratégico politica e economicamente na região. Já Chichén Itzá foi o sítio mais proeminente das terras maias do norte no período Clássico Terminal (800-1050 d.C.). Este assentamento foi um destacado centro regional, estabeleceu o controle de rotas comerciais e de bens de consumo de luxo, além de desempenhar uma posição de coletor de impostos a sítios menores subjugados ao seu poder (COBOS, 2001) (NAVARRO, 2012).
Luz e cor na apropriação de imagens no Brasil
Authors:   Universidade Estadual de Campinas, Midlej Dilson Rodrigues
Published: April 2023

A apropriação e o consequente trânsito de imagens entre períodos histórico-artísticos sempre representou, na história da arte ocidental, um papel constante e determinante na consolidação dos valores da civilização. Essa tradição revigora-se nos procedimentos da arte moderna, assume uma conotação irônica e fragmentada na visualidade contemporânea (ou pós-moderna) e estabelece-se como fator preponderante na discussão dos limites de autoria, criatividade e valoração, sendo um dos principais recursos estilísticos da arte contemporânea. Essas características são também observadas na produção artística contemporânea brasileira, conforme o que tentaremos caracterizar neste artigo, espaço onde levamos em consideração o fato das representações formarem sistemas visuais ? [...] que constituem a nossa imagem do mundo e ?que a história humana é a história de como esse sistema de representações se altera com o tempo.
Reflexões sobre o papel de Arminda em "Quanto vale ou é por quilo?" (Sérgio Bianchi, 2005)
Authors:   Universidade Estadual de Campinas, Arruda Douglas Gasparin
Published: April 2023

Há, no filme Quanto vale ou é por quilo? (2005, Sérgio Bianchi), uma série abrangente de provocações. Bianchi, nesse filme, nos coloca diante do incômodo exercício de refletir acerca de problemas polêmicos do seu contexto de produção: a exploração sem limites da miséria humana; o cinismo das elites em seus discursos sobre o cuidado social; a corrupção das instituições do terceiro setor da economia; a permanência do racismo e seus mecanismos de exclusão. Segundo Nezi Heverton e Luis João Vieira, Bianchi é marcado por esses elementos, pelo choque, a ironia, pelo discurso que não poupa ninguém, por uma orientação de mundo a tal ponto distópica que já não há espaço para personagens redentores, para ações moralizantes, para desfechos revolucionários capazes de gerar uma sociedade ideal.

Published: April 2023

O câncer de colo uterino, uma das neoplasias mais comuns em mulheres, apresenta metástases em cerca de 13% dos casos no momento do diagnóstico, localizadas mais comumente em pulmão e fígado. Nesses casos, não há consenso sobre o tratamento de primeira linha, devendo-se considerar a apresentação clínica da paciente, sendo mais habitualmente utilizada a quimioterapia. É de conhecimento médico que implantes secundários de câncer colorretal e de tumores neuroendócrinos primários podem ser ressecados com segurança promovendo aumento de sobrevida do paciente. No entanto, novos estudos ainda estão sendo desenvolvidos sobre a alteração de mortalidade em casos de metástases secundárias à câncer de colo uterino. O objetivo desse artigo é relatar o caso de uma paciente com câncer cervical estadiamento IB que evoluiu com implantes pulmonares secundários sendo submetida a metastasectomia pulmonar em 2 tempos com quimioterapia adjuvante e, posteriormente, com metástases hepáticas sendo realizada segmentectomia hepática por intolerância à quimioterapia, e posterior reincidências dos nódulos hepáticos.
Management of oligometastatic disease in soft tissue sarcomas
Authors: Gonzalez Marcos R.
Published: April 2023

Oligometastatic soft tissue sarcoma represents an intermediate state between localized and disseminated disease. Combination A combination of surgery, radiotherapy and systemic treatment significantly improves prognosis, with a 5-year overall survival as high as 50%. Due to the high prevalence of lung metastases, most of the surgical evidence is centered around lung metastasectomy. The decision to perform surgical metastasectomy remains dependent on optimal patient selection. Adequate post-surgical lung function, absence of extrapulmonary metastases, control of the primary tumor, and feasibility of achieving negative margins are major criteria for patients to undergo successful surgery. Adequate margins, longer disease-free interval, unilateral, limited number (≤ 2), metachronous and small (< 2 cm) pulmonary metastasis are some factors associated with improved survival. Radiotherapy, especially SBRT, is an effective treatment for disease control, and its use as (neo)-adjuvant therapy has shown promising results. However, studies comparing radiotherapy against surgery are missing and the efficacy of radiotherapy independent of surgery is not yet clear. Interventional radiology techniques such as percutaneous thermal ablation (PTA) or arterial embolization have also been described as potential treatment alternatives in candidates deemed not fit for surgery. Systemic treatment has traditionally consisted of an anthracycline (doxorubicin)-based regimen with the addition of ifosfamide in certain cases. Recent advances in systemic treatment include the use of targeted therapy and immunotherapy in (oligo)-metastatic STS. However, except for certain histologies, most STS subtypes are chemoresistant, and the response to systemic treatment is poor.

Biological literacy is the individual's ability to determine the prior knowledge to understand the terms, concepts, procedural, benefits, and relationships of biological sciences in life. This study aims to measure students' biological literacy skills. This study approach was conducted descriptively, with grades, levels, and material indicators utilized to assess biological literacy skills. The population in this study was students from grade X Mathematics and Natural Sciences, Baitul Qurro Islamic Senior High School, with a sample size of 44 students drawn from the overall population. The instrument employed was a multiple-choice with up to 15 items about viruses related concepts. The data were analyzed descriptively. The results of this study revealed that 50% of students have low biology literacy skills. The highest percentage of students' biological literacy skills was found in indicator 4 (interpreting the role of viruses in life), 61%, while the lowest was in indicator 3 (analyzing virus replication), with 42%. The percentage of students' literacy skills in each level of biological literacy was highest at the structural level, with 58%, while the lowest was at the nominal level, with 44%. The low level of student biological literacy indicates that research is needed to find the right strategy to improve biological literacy skills in learning.

Rural English Teachers' Emotional Labor: A Case Study from a Chinese Middle School
Authors: Deng Minghui
Published: April 2023

This study used a qualitative research method to explore rural English teachers' emotional labor strategies and the factors that influence their emotional labor through interviews. The study found that rural English teachers used more genuine expression strategies and surface acting strategies and less deep acting strategies; teachers used more genuine expression strategies in their interactions with students and colleagues and more surface acting in their interactions with parents and leaders, among which, since most rural students are stay-at-home children, teachers need more emotional labor to communicate with their guardians; therefore, teachers mostly used surface acting, but hardly used deep acting and genuine expression strategies. Factors that influence their emotional labor include teachers' personalities, teaching experiences, colleague relationships, school rules about teachers' emotions, and teacher faculty status. Based on the findings, this study proposes recommendations to improve rural English teachers' emotional labor in order to promote the development of rural English teachers.

The results of this study indicate that each informant has a strategy in providing assistance during puberty. Two informants use a catalyst strategy, and one informant uses a hanging sword strategy.
Paresthesia and Pain in Both Arms when Shampooing One’s Hair: Symptoms of Neurogenic Thoracic Outlet Syndrome
Authors: Kim Ji-Yeong , Son Byung-chul
Published: April 2023

Neurogenic thoracic outlet syndrome (TOS) is a clinical diagnosis based on the reproduction of a patient’s symptoms with a provocation test (arm elevation) after excluding other conditions that might cause similar symptoms. Neurologic symptoms and signs can vary from mild paresthesia and numbness to intrinsic hand muscle atrophy. The main controversy in patients with neurogenic TOS involves neurologic-type complaints of paresthesia, numbness, and pain. However, there is no positive objective test to identify the cause. A 54-year-old female patient presented with numbness and radiating pain in her bilateral arms that occurred every time she bowed her head while shampooing. The patient had a history of two neck sprains due to slipping before the onset of symptoms. In addition to pain and numbness in both arms at arm elevation, pain in the suprascapular and occipital areas was also present. After excluding cervical nerve root lesions and other bone abnormalities, the patient's symptoms disappeared by brachial plexus decompression through a supraclavicular approach. It is difficult to diagnose neurogenic TOS with pain and paresthesia without muscle weakness in the upper extremities. If physicians do not consider the possibility of neurogenic TOS in patients with upper extremity paresthesia and pain, unnecessary multiple treatments may be performed, prolonging patients’ suffering. The exacerbation of pain and paresthesia in both arms and hands can occur immediately after the head is lowered during shampooing. This can be interpreted as a characteristic symptom of a constricted interscalene triangle and brachial plexus compression caused by hyperabduction of the arm.
