The Role of Indonesian Language Learning in Shaping the Character of Students
Authors: Hoerudin Cecep Wahyu
Published: February 2022

The function of language, particularly Indonesian, in moulding the character of a student is critical, and this is true both orally and in writing. An Indonesian instructor must understand that learning the language is about developing language skills rather than mastering the grammar of the language. Because of this, this study emphasized the issue of improving the competence of Indonesian language teachers so that they can better serve their students. In order to uncover the subject of inquiry, this study employs a qualitative technique combined with descriptive methodologies. According to the findings of the study, learning the Indonesian language has a major impact on the development of students' personalities and character. It is possible to receive assistance by learning to read and write as well as speak and listen.
The Effects of Odd or Even Number of Options on The Variance of Item Validity in Environmental Personality (Big-Five Personality)
Authors: Datau Rahmirini , Putrawan I Made , Rahayu Wardani
Published: February 2022

Validity is one of the important characteristics in any psychological measuring tool. Measurement tools in his research more generally include a variety of observations and usually include responses that aim to regulate and limit the choices available to respondents and assessments. There are many studies that have assessed how the number of response options on a scale affects validity and reliability, but fewer have discussed whether the midpoint should be included as a response option, or whether the scale is even. Regardless of where the response scale is in psychological measurements, the environmental personality (big-five personality) scale has been expanded and elaborated in various ways in previous research since the introduction of dreams. The big-five personality model is the most extensive model for measuring environmental personality. This study aims to determine whether there is a difference between the number of odd and even option scales on the validity variance of students' environmental personality (big-five personality) items, and to see which scale of the number of options is better or suitable for the environmental personality (big-five personality) instrument. The calculation data were analyzed using the one-way ANOVA method. The results of this study indicate that the scale of the number of odd options (five options) and the scale of the number of even options differ significantly in the variance of the validity of the environmental personality items (big-five Personality). The mean plot results show that the odd option scale higher than the even scale. This research can be carried out for further research in using the odd scale on the environmental personality measurement tool (Big-five Personality) with the expansion being studied.
KONSEP EKONOMI KERAKYATAN BERBASIS HUKUM TRANSENDENTAL

Published: February 2022

An economic system based on the paradigm of Pancasila values, placing the position of the people as the Caliph of Allah SWT on earth, oriented to the common good is what is meant by People's Economy (economic democracy). There is a fundamental difference between the economic system in a country that adheres to a liberal-capitalist democracy and a socialist democracy, the Pancasila populist economy, and an economy that is developed within the framework of spiritual values ​​such as the value of divinity (Tawhid). The emergence of political investors whose interests are accommodated from the transactional system, including the hegemony of capitalism which has an effect on globalization, causing the market in the financial center of national boundaries, is the application of a democratic system that comes out of the values ​​and paradigms of Pancasila. This is an ideological problem, so that the transcendental dimension in the populist economy needs to be re-grown to fight the threat of globalization and new forms of capitalism, by restoring the transcendent values ​​of Pancasila into the building of economic, legal and political systems in Indonesia.

El derecho a la desconexión digital no se aplica en la realización de un curso de formación on line obligatorio que, conforme al convenio colectivo, computa como tiempo de trabajo efectivo. La negativa del trabajador (controlador aéreo) a cumplir, tempestivamente, la orden empresarial de realizar dicho curso de formación, sin que quede acreditado que se haya vulnerado su derecho al descanso, no está justificada.

Le droit à la déconnexion numérique ne s'applique pas à l'achèvement d'une formation obligatoire en ligne qui, conformément à la convention collective, est calculée comme du temps de travail effectif. Le refus du travailleur (contrôleur aérien) de se conformer, dans les meilleurs délais, à l'ordre commercial de réaliser cette formation, sans qu'il soit prouvé que son droit au repos a été violé, n'est pas justifié.

Judging By The Methodology Of Learning Islamic Education Which Eroded The Times
Authors: Ainun Mardia Harahap
Published: February 2022

Learning methodology is part of the set of scientific disciplines that become its parent. Almost all sciences have their own methodologies. Therefore, Islamic education as one of the disciplines has a methodology, namely the method of Islamic education. Islamic education from year to year resulted in many changes in the Islamic world. Both in terms of religion, education, politics and so on. Especially in the field of Islamic education, due to the attitude of the educators who are permissive and indulgent, many children fall into associations that ignore the Shari'ah. Many educators forget their nature as uswahnya students who are obliged to educate students to have good morals. This results in the child's world being in vain. Giving quite a lot of contribution to the futility of the western educational methods that seem to have become the mecca of our education. So that every educator uses more general education methods, even the methods used in their learning programs are by using the lecture method, question and answer, discussion, demonstrators, and so on. This naturally erodes the understanding of educators and students on Islamic education methods. Actually Islam has a perfect education method for mankind, especially in the field of Islamic education. Therefore, educators return to their hittah, namely mastering Islamic education methods, so that the function of Islamic Education Methods will later help realize and carry out the goals of education it self.
Retribution, restoration and the public dimension of serious wrongs

Retribution, restoration and the public dimension of serious wrongs

Restorative justice has been criticised for not adequately giving serious consideration to the ‘public’ character of crimes. By bringing the ownership of the conflict involved in crime back to the victim and thus ‘privatising’ the conflict, restorative justice would overlook the need for crimes to be treated as public matters that concern all citizens, because crimes violate public values, i.e., values that are the foundation of a political community. Against this I argue that serious wrongs, like murder or rape, are violations of agent-neutral values that are fundamental to our humanity. By criminalising such serious wrongs we show that we take such violations seriously and that we stand in solidarity with victims, not in their capacity as compatriots but as fellow human beings. Such solidarity is better expressed by organising restorative procedures that serve the victim’s interest than by insisting on the kind of public condemnation and penal hardship that retributivists deem necessary ‘because the public has been wronged’. The public nature of crimes depends not on the alleged public character of the violated values but on the fact that crimes are serious wrongs that provoke a (necessarily reticent) response from government officials such as police, judges and official mediators.
Poverty Reduction Strategies in Developing Countries
Authors: Ayoo Collins
Published: February 2022

The existence of extreme poverty in several developing countries is a critical challenge that needs to be addressed urgently because of its adverse implications on human wellbeing. Its manifestations include lack of adequate food and nutrition, lack of access to adequate shelter, lack of access to safe drinking water, low literacy rates, high infant and maternal mortality, high rates of unemployment, and a feeling of vulnerability and disempowerement. Poverty reduction can be attained by stimulating economic growth to increase incomes and expand employment opportunities for the poor; undertaking economic and institutional reforms to enhance efficiency and improve the utilization of resources; prioritizing the basic needs of the poor in national development policies; promoting microfinance programs to remove constraints to innovation, entrepreneurship, and small scale business; developing and improving marketing systems to improve production; providing incentives to the private sector; and, implementing affirmative actions such as targeted cash transfers to ensure that the social and economic benefits of poverty reduction initiatives reach the demographics that might otherwise be excluded.
Bridging the Gap: Nasoalveolar Moulding in Early Cleft Palate Rehabilitation
Authors: Nadia Ferreira Amanda
Published: February 2022

Orofacial clefts (OFC) are among the commonest birth defect in developed and developing countries alike. In underdeveloped and developing countries, babies born with oral clefts are generally anaemic with low birth weight and may be unfit for surgery. The surgical reconstruction is also challenging and the aesthetic outcome cannot be guaranteed by the surgeon. Presurgical nasoalveolar moulding (PNAM) has been suggested to bridge the gap between the clefted segments before surgical repair. It is a simple yet effective technique that needs to be initiated at the right time and age to achieve ideal functional and aesthetic outcomes. This chapter highlights the effectiveness of the nasoalveolar moulding technique and details the manner in which the appliance is fabricated and activated.
Pediatric Ulcerative Colitis
Authors: Shentova-Eneva Rayna , Yankov Ivan
Published: February 2022

Inflammatory bowel disease (IBD) is a collective term that includes a group of disorders with unknown etiology characterized by chronic inflammation of the gastrointestinal tract and relapsing and remitting course. Ulcerative colitis (UC) is a type of IBD that affects the large intestine, causing irritation, inflammation, and ulcers in its lining. Approximately 25% of patients with IBD are diagnosed before the age of 18 years. Children and adolescents with UC are more likely to have more severe disease course with more extended intestinal involvement at diagnosis and faster disease progression than adults. Atypical presentation is also common in pediatric age. Treatment recommendations for children and adolescents are different than those for adults and offer many unique challenges for the healthcare professionals.

Published: February 2022

Ulcerative colitis (UC) is a chronic, idiopathic inflammatory disease that affects mainly young adults. The histologic examination of endoscopic biopsies or resection specimens plays an important part in the diagnosis and follow up of patients with inflammatory bowel disease, including UC. In this chapter, we discuss on main histological features that can be used when analyzing endoscopic biopsies, as well as features that can be evaluated in surgical samples of patients with UC. The differential diagnosis toward Crohn’s disease and other mimickers is emphasized. In addition, the main complications associated with treatment and long-standing diseases, such as infection colitis and dysplasia are presented.
An Overview of the Potential Effects of Melatonin Supplementation on Athletic Performance
Authors: Souissi Amine , Dergaa Ismail
Published: February 2022

Context: Melatonin is a hormone synthesized principally in the pineal gland that has been classically associated with endocrine actions. Exogenous melatonin is often used to treat insomnia and enhance sleep quality in a range of situations, including jet lag. However, the benefit and safety profile of daytime melatonin dosing prior to exercise are unknown and warrant additional exploration. Objectives: We aimed to give (i) a brief overview of the beneficial effects of exogenous melatonin administration on sports performance and (ii) some recommendations for acute use of melatonin with a special focus on humans’ physical activity and athletic performance. Evidence Acquisition: To ascertain the effect of exogenous melatonin administration on humans, a systematic search of the literature was undertaken using PubMed, ScienceDirect, Medline, Google Scholar, and Scopus. Numerous studies in animals have demonstrated the positive impact of melatonin treatment during physical exercise. However, uncertainty remains regarding exogenous melatonin administration on human’s physical performance. Therefore, the present review focuses almost entirely on data obtained from humans. Results: The gathered data indicate that consuming melatonin at night improves sleep quality. In terms of physical activity and sports performance, previous research has demonstrated that melatonin administration has a good effect on decreasing oxidative stress and inflammation induced by exercise. However, in some specific situations, the daily administration of melatonin may have an unfavourable influence on performance during acute and strenuous exercise. Conclusions: Exogenous melatonin administration prior to exercise shows significant chronobiotic, antioxidant, antiadrenergic, and hypothermic effects and may represent a fascinating potential weight loss method. However, consuming a high amount of melatonin (6 mg) 50 minutes prior to commencing exercise is not recommended as it may interfere with the physiological reactions to physical activity. Melatonin-related adverse effects were mainly transient and were associated with daytime doses. Melatonin should therefore be consumed at night whenever possible.
Is It Possible to Age Healthy Performing Ultra-endurance Exercises?
Authors: Vancini Rodrigo Luiz , dos Santos Andrade Marilia , Andre Barbosa de Lira Claudio , Theodoros Nikolaidis Pantelis , Knechtle Beat
Published: February 2022

Context: The process of decline in endurance capacity is particularly insidious over age 60 and varies considerably with sex, task specificity, and individual training status. Around 50 years of age, aging also implies deterioration of neuromuscular function, affecting muscle strength and power. The aim of the present article was to perform a mini-review to verify how ultra-endurance exercises impact the aging process. Evidence Acquisition: For this, we reviewed the PubMed database (on 20/01/2022) by crossing the key terms, in the simple form, “ultra AND endurance AND exercise AND aging”. This research provided 25 articles from which we made a selection. Results: We observed that the number of articles on the topic is low. The main findings showed that ultra-endurance exercise, high volume physical exercise (six-hours or more) with peak intensity moments, in long-term, is associated with increased risk of heart disease, sudden death, shortening of telomeres, accelerating aging cell, and harm to the healthy aging process and longevity. Conclusions: There is still little literature about the impacts of ultra-endurance practice on the aging process. Although there are indications that this may happen, such as shortening of telomeres and cellular aging, it is still not possible to establish a cause-effect relationship. Furthermore, it is not just about physical exercise, it is necessary to take into account individual factors (intrinsic and extrinsic) that interact with the sports trajectory, life habits, biology, and genetics.
Isolation of Brucella melitensis from Lumbar Vertebrae in Patient with Initial Misdiagnosis: A Rare Case with Spinal Epidural Abscess, Spinal Stenosis, and Brain Lesion
Authors: Alamian Saeed , Dadar Maryam , Etemadi Afshar , Bosilkovski Mile , Alamian Mohammad Mehdi
Published: February 2022

Introduction: Brucellar spondylodiscitis is among the most typical forms of osteoarticular involvement that still challenges clinicians and scientists for early diagnosis. Case Presentation: We describe the isolation of Brucella melitensis from vertebrae in a man with spondylodiscitis who had osteoarthritis as an underlying condition. The patient showed negative results on blood samples' serological, molecular, and culture tests and had low-back pain, restricted lumbar movements, headache, poor appetite, and fatigue for the past nine months. He had a history of regular ingestion of raw cow milk and milk products for a long time. First, he was misdiagnosed as lumbar disc herniation and then underwent nonsteroidal anti-inflammatory drugs and myorelaxants treatment. The lack of fast diagnosis and appropriate treatment led to severe complications of the disease. Three months after the first magnetic resonance imaging (MRI), the findings of the second MRI without intravenous contrast showed right lateral recess and canal stenosis at L4 - L5 with narrowing the thecal sac at the disc space. Abnormal enhancement of the endplates at L4 - L5 with relating epidural space-enhancing tissue in the setting of spondylodiscitis and the associated epidural abscess was seen behind L4. Moreover, extensive high signal abnormalities in paraspinal tissues at L3, L4, L5, S1, S2, and S3 were notable. The diagnosis was approved by isolating B. melitensis biovar 1 from the culture of the vertebrate body. The Brucella isolate was characterized by Bruce-ladder PCR, AMOS PCR, and classical biotyping. The patient was treated successfully with surgical intervention and triple-antibiotic, including oral doxycycline 100 mg/12 h plus oral rifampin 300 mg/12 h for three months and intramuscular streptomycin 1 g daily for the first two weeks. The patient’s general condition and low-back pain were remarkably improved in the follow-up. Conclusions: Patient histories and a series of different diagnostic procedures such as MRI, serology, molecular, and cultural tests are essential to make a rapid and accurate diagnosis of brucellar spondylodiscitis, thereby reducing the delay for brucellar spondylodiscitis treatment.

Published: February 2022

Background: The nature of breast cancer (BC) and its treatment is such that it leads to physical and psychological complications. Objectives: The present study aimed to determine the effect of supportive educational intervention on the perceived stress and severity of chemotherapy-related neuropathy in BC patients. Methods: This quasi-experimental study was carried out on 60 women suffering from BC in Zahedan, Iran, in 2020. The patients were selected using the convenience sampling method and randomly assigned into two groups of intervention and control. The patients in the intervention group received four 45-minute sessions about the common problems of BC on a weekly and individual basis. The control group received only routine ward care. Data collection tools were the Perceived Stress Scale (PSS) developed by Cohen and Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) Pain Scale. Data were collected before the intervention and six weeks after the intervention. Data analysis was performed using SPSS 22 software. Results: The results of independent t-test showed that the mean and standard deviation of perceived stress score in the intervention group decreased from 56.8 ± 5.92 to 50.36 ± 3.89 (P < 0.001), and in the control group decreased from 55.6 ± 3.65 to 54.8 ± 3.53 (P = 0.258). The mean and standard deviation of neuropathy severity score in the intervention group decreased from 12.90 ± 1.66 to 8.43 ± 2.16 (P < 0.001), and in the control group increased from 12.56 ± 2.28 to 13.03 ± 1.93 (P = 0.276). The independent t-test showed that after implementing the supportive educational intervention, there was a significant difference between the two groups in terms of mean and standard deviation of neuropathy severity score (P < 0.001). Conclusions: According to our results, supportive educational intervention reduced the perceived stress and severity of neuropathy. Thus, it is necessary to include these supportive interventions in educational and care programs to improve patients’ psychological status and reduce stress and neuropathy.
Do Facebook and Instagram differ in their influence on life satisfaction? A study of college men and women in South Korea
Authors: Choi Jounghwa
Published: February 2022

While a number of previous studies examined the impacts of social networking sites (SNSs) on young people’s well-being, they usually focused on a single platform without considering the increasing use of multiple social media platforms. In addition, only a few studies have explored gender differences, and empirical evidence outside Western culture is still lacking. To this end, the present study explores how two different types of use (i.e., active vs. passive) of the two most popular SNS (social network sites) platforms (i.e., Facebook and Instagram) are related to college men’s and women’s life satisfaction via social support and social comparison in South Korea. Path analyses conducted using data from a nationwide online survey of Korean college students (N = 360) revealed that active use contributes to life satisfaction via perceived social support on SNSs, while passive use decreases life satisfaction via negative social comparison on SNSs. Both active Facebook and Instagram use are related to perceived social support, while negative social comparison tends to be related only to passive Instagram use. Gender differences were not observed in the hypothesized relationships except for those involving the control variables (i.e., the amount of overall SNS use and the number of SNS platforms used). The results suggest that the influences of SNS use on subjective well-being depend on the types of SNS use and the nature of the platforms. The practical implications for social media literacy education are discussed.

The Internet has given rise to many new communication tools (e.g., social media, text messaging), which, while beneficial in many respects, have become a means for aggressing against others. As evidence of the adverse correlates of cyber aggression mounts, improved understanding of the mechanisms that facilitate electronic aggression is needed. Moral disengagement (i.e., cognitive processes through which individuals disengage from their moral values) has been shown to predict cyber aggression when assessed as a unitary construct. The present study investigated the eight moral disengagement mechanisms measured by the Moral Disengagement Measure (Detert et al., 2008) and their relationships to four types of cyber aggression perpetration assessed with the Cyberbullying Experiences Survey (i.e., malice, public humiliation, deception, and unwanted contact; Doane et al., 2013). Emerging adults (N = 404, 58.67% women) aged 18 to 29 (M = 25.16, SD = 2.76) recruited through Amazon.com’s MTurk website completed measures online, and data were analyzed via path analysis. Each type of cyber aggression perpetration was predicted by different moral disengagement mechanisms. Advantageous comparison and dehumanization were the strongest predictors, and dehumanization was the only mechanism to predict all forms of cyber aggression. These findings provide support for the role of these mechanisms in cyber aggression and suggest that examining moral disengagement mechanisms individually may help to improve our understanding of cyber aggression among emerging adults. Further clinical and research implications are discussed.

The seventh chapter focuses on an illustrative demonstration of the application of tactical urbanism and tactical mapping on the example of the city of Brno. Here we used six related tactics. First, in cooperation with the Advisory Board for a Barrier-Free Brno, we identify the types of spaces of priority interest. Then (also in cooperation with the Brno City Advisory Board for Accessibility) we prioritize places and institutions that are key for people with disability. In the third tactic, we identify the spatial concentrations of these priority places (in order to identify priority areas). We then identify barriers in the prioritized areas through field research and categorize these into several classes. We then subject each barrier to an assessment of how challenging it is to remove - either in terms of the nature of the barrier or through the lens of ownership/management of the barrier. In the final sixth tactic, we design comprehensive barrier-free routes connecting priority institutions and focusing on removing precisely those barriers that would provide the greatest "benefit" (i.e., most help to make the route more accessible) in the spirit of tactical urbanism. The design of the tactical mapping process is not one-size-fits-all and openly deals with dead ends. For example, it has been shown that it is not necessary to use sophisticated instruments to successfully describe the nature of barriers (but a common smart phone will suffice) or that barriers cannot be narrowed down to point objects, but we must also work with linear barriers (such as missing guide lines, warning strips, etc.). It is also important to have a broader interdisciplinary team involved in tactical mapping - in addition to social geographers and cartographers, this includes barrier specialists (so that barriers in space can be clearly identified) and public administration representatives who are in charge of accessibility. However, it should be taken into account that this is an illustrative example working in a specific city. Although we expect that the transferability can be high (especially to similarly sized cities), it is important to utilize the methodology for the realities and needs of a particular settlement. The purpose of anchoring our methodological approach in Brno is to provide guidance on where to start and how to approach the mapping. The resulting implementation is then always personalized for the specific city.

Background: Nail involvement in psoriasis may be assessed clinically, ultrasonologically, and dermoscopically. The aim of this study was to assess the dermoscopic features of nails in psoriasis, compare them with clinical findings, and correlate them with the Nail Psoriasis Severity Index (NAPSI) score.
Methods: We recruited 120 patients with psoriatic nail changes for the study. The Psoriasis Area Severity Index (PASI) was used to assess the severity of disease. Clinical and dermoscopic (DermLite DL4, ×10, polarized and non-polarized) nail examination determined NAPSI, modified NAPSI (mNAPSI), and NAPSI determined with dermoscopic findings (dermoscopic NAPSI [dNAPSI] and dermoscopic modified NAPSI [dmNAPSI]) were used to assess severity of nail involvement.
Results: Subungual hyperkeratosis (50.8%) and nail plate thickening (56.7%) were the commonest clinical nail changes found, and dermoscopically, they were subungual hyperkeratosis and pitting (68.3% each). The average median with interquartile range of PASI and NAPSI scores were 7.5 [5.7-10.8] and 8.0 [6-12], respectively. NAPSI scores increased significantly with the increase in PASI scores (P < 0.001). A comparison of NAPSI and mNAPSI with dNAPSI and dmNAPSI revealed that NAPSI, mNAPSI, and dNAPSI increased significantly with an increase in PASI scores. dNAPSI scores increased significantly with increased mNAPSI and dmNAPSI, and mNAPSI and dmNAPSI were significantly good predictors of joint involvement in psoriasis.
Conclusions: Dermoscopy allows for better visualization of nail findings. Evaluating NAPSI and mNAPSI scores in conjunction with dNAPSI and dmNAPSI increases their helps detect early psoriasis, detection of worsening moderate-to-severe psoriasis (PASI >10) and predict joint involvement and their severity

Atopic dermatitis is a Th2 disease, due to relapse of IL-4 and IL-13 by Th2 cells. Despite the approval by FDA of dupilumab, the first monoclonal antibody for the severe forms, traditional drugs remain a milestone for the treatment of this dermatosis. Dermatologists need a good knowledge of all therapies for an integrated and personalized management of patients.
