Background: Knowing the development pattern of children’s language is applicable in developmental psychology. Network models of language are helpful for the identification of these patterns. Objectives: We examined the small-world properties of featured semantic networks of developing children. Materials & Methods: In this longitudinal study, the featured semantic networks of children aged 18-30 months were obtained using R software version 3.5.2 and the igraph software package. The data of 2000 English (British)-speaking children, half boy and half girls, were gathered from existing databases of MCDI (between 2000 and 2007) and McRae feature norms. The growth pattern of these networks was illustrated by graph measures. Comparing these measures with those of the reference random networks, the small-world structure can be examined. Results: To have a comparison between path length and clustering coefficient of featured semantic networks with those of random networks, we computed the Q quotient. The results showed that the values of the Q quotient at 18, 22, 26, and 30 months of age were all more than 1, which confirms the small-world characteristic of the networks. Conclusion: Featured semantic networks of children exhibited a small-world structure, in which there was a local structure in the form of clusters of words. For global access, some words act as bridges connecting semantically distant clusters. These networks possess small-world property from the early months of age. The small-world structure cannot be seen in the less dense networks built with a higher cut-off threshold.

Background and Aim: Chronic low Back Pain (CLBP) is one of the most common musculoskeletal disorders with possible psychological consequences for the patients. This study aimed to review all evidence on the effectiveness of psychological interventions in improving the mental status of people with CLBP and providing recommendations for future therapeutic interventions. Methods and Materials/Patients: This systematic review was conducted on the articles published from January 2010 to December 2020. The keywords included “psychology”, “intervention”, “low back pain”, “chronic disease”, “quality of life”, “empowerment”, “psychotherapy”, “psychological interventions”, “clinical trials”, and “randomized clinical trials” in the indexing databases of Magiran, PubMed, Scopus, and Google Scholar. Of the total 1740 articles found, 14 articles were selected for review. Results: The results showed that Cognitive-Behavioral Therapy (CBT) and its combination therapies with mindfulness techniques played an influential role in improving psychological status and quality of life, and reducing pain perception in CLBP patients. The lack of RCT (randomized controlled trial) research and follow-up to assess long-term outcomes are the main limitations of the studies conducted in Iran. Conclusion: It is recommended that psychological interventions be considered alongside medical therapies to improve CLBP patients’ adjustment to chronic condition and their quality of life. Researchers and therapists should consider treatment programs based on RCT plans and long-term follow-up.

Published: November 2021

Background and Aim: The major concerns related to the Endoscopic Endonasal Transsphenoidal (EET) surgery for sellar and suprasellar tumors include the risks of post-operative Cerebrospinal Fluid (CSF) leak, leading to morbidity and at times mortality, due to severe meningitis. Time is required to develop possible preventive measures that can reduce the risk of post-operative CSF rhinorrhea. The present study aimed to evaluate the effects of pre-operative CSF diversion by lumbar drainage in EET tumor surgeries on preventing post-operative CSF leak and its effect on the length of hospital stay. Methods and Materials/Patients: We conducted a prospective study on 20 patients with a pituitary tumor that underwent EET surgery between October 2018 and December 2019. Preoperative Lumbar Drain (LD) was inserted after induction in all explored patients. The tumor was excised with continuous intraoperative CSF drainage. Post-operatively, the LD was kept for 3 days and clamped for the next 24 hours. If no evidence of CSF rhinorrhea was present, it was removed. Complications related to CSF drainage, CSF leak, and hospital stays were evaluated. Results: Our study population consisted of 13(65%) men and 7(35%) women, with Mean±SD age of 39.8±10.71 years. The most commonly presented complaint was visual disturbance (60%) and the least common symptom was urinary disturbance (5%). The intra-operative leak was detected in 9(45%) patients, while the post-operative leak was present in only 1(5%) patient. LD blockage significantly contributed to post-operative CSF leak (P=0.001). The Mean±SD hospital stay in the post-operative period was 8.85±3.22 days with 65% of patients having a hospital stay of <7 days. Other post-operative complications (e.g. diabetes insipidus, electrolyte imbalance, and hormonal disturbances) were mainly responsible for prolonged post-operative hospital stay (P=0.001). Conclusion: Pre-operative LD, apart from helping to reduce the incidence of post-operative CSF leak, is not associated with an overall increased post-operative hospital stay.

Published: November 2021

Background and Importance: Spinal Subdural Hematoma (SSH) is a rare condition with an unknown incidence in the general population. Iatrogenic spinal subdural hematoma radiologically mimicking a prolapsed dorsolumbar disc has not been published in the literature. Case Presentation: A 65-year-old female presented with altered sensorium and generalized weakness for 3 days evaluated by a neurologist who diagnosed it as a metabolic encephalopathy with Syndrome of Inappropriate Antidiuretic Hormone secretion (SIADH) with severe anemia and hypothyroidism. She underwent a diagnostic lumbar puncture and following which, within 24 hours, she developed weakness of both the lower limbs. MRI of dorsolumbar spine was done which revealed D12-L1 extruded disc causing severe compression to the conus medullaris with D12-L2 subarachnoid lesion and cord edema. On opening the dura, a large organized hematoma on the anterior aspect of the conus was seen and evacuated. Conclusion: Spinal subdural hematoma presents with a spectrum of signs and symptoms. Although MRI is the investigation of choice but SSH presenting like a prolapsed intervertebral disc on MRI is one of its kinds and should be kept in mind since it carries a grave prognosis if not treated early with emergency decompression.

Objective: An increase in post-marital relationships has had adverse consequences. One of the consequences is family dissolution and the breakdown of social units (families). The present study aimed to study the processes and contextual factors of marital infidelity. Methods: This qualitative study was conducted using the grounded theory method. The research population included couples who experienced marital infidelity. A total of 32 participants were selected using the purposive sampling method in 2019. We conducted semi-structured interviews with the participants to collect the study data, and the interviews continued until the data saturation. The collected data were systematically analyzed in three stages of open, axial, and selective coding. Results: Analysis of the data collected revealed 51 codes extracted through open coding. Then, the extracted codes were merged into 10 categories via axial coding. These categories included four themes: the formation of the context of marital infidelity, predictions of marital infidelity, engaging in marital infidelity, and the consequences of marital infidelity. Conclusion: Given that marital infidelity is a complex and multifaceted phenomenon, the insights from this study can be used to develop models to identify and prevent predictors of marital infidelity.

Authors:   Department of Psychology, Faculty of Humanities, University of Bojnord, Bojnord, Iran., Alavi Khadije
Published: November 2021

Objective: This study aimed to investigate the role of social safeness and self-compassion, as two essential components of Gilbert’s theory, in mental health. In this regard and based on theoretical foundations, the mediation model of the relationship between social safeness and mental health problems was examined through self-compassion as a mediator. Methods: A total of 344 students from the University of Bojnord, Bojnord City, Iran, in the 2019-2020 academic year were recruited using the cluster sampling method. They were responded to the social safeness and pleasure scale, self-compassion scale (short form), and depression, anxiety, and stress scale. The obtained data were analyzed using Structural Equation Modeling (SEM). Results: The mediation model showed a good fit (χ2⁄df: 1.77; RMSEA: 0.043; CFI: 0.99; GFI: 0.98; AGFI: 0.96; NFI: 0.98; TLI: 0.98). Beta coefficients indicate significant direct effect of social safeness on self-compassion (Beta=0.57; P≤0.001), significant direct effect of self-compassion on mental health problems (Beta=-0.75; P≤0.001), as well as a significant indirect effect of social safeness on mental health problems (Beta=-0.42; P≤0.001). Conclusion: Social safeness affects mental health problems (depression, anxiety, and stress) through self-compassion as a mediator. A high sense of social safeness protects against depression, anxiety, and stress through increasing self-compassion. However, low social safeness increases vulnerability to depression, anxiety, and stress by reducing self-compassion.

Background: This study aimed to prospectively record changes to treatment for early breast cancer patients during the first wave of the COVID-19 pandemic in Australia.  The purpose was to assess the impact on breast cancer outcomes and to determine the need for any mitigative actions. 
Methods: The study was conducted in the breast cancer unit of a tertiary referral hospital. Patients with early (non-metastatic) breast malignancy discussed in multidisciplinary team meetings between March and June 2020 were included. Patients were newly diagnosed, post-operative or post-neoadjuvant chemotherapy. Standard treatment was defined by Westmead Breast Cancer Institute protocols and any variations related to the pandemic were recorded.
Results: In the study, 145 patients were included (median age 59 years). Pandemic-related changes to management were noted in 13 of 145 (9.0%) patients. Four patients experienced a delay to cancer treatments, four were not offered reconstructive/ symmetrisation surgical procedures, three had altered radiotherapy protocols and two patients were not offered enrolment to a clinical trial. These impacts affected the groups presenting with new cancers (n=7/86, 8.1%), post-operative cases (n=4/25, 16.0%) and post-neoadjuvant chemotherapy cases presenting for surgical planning (n=2/34, 5.9%). 
Conclusion: Most patients (91.0%) received standard treatment during the first wave of the pandemic. The minor variations from institutional protocols observed in this study are unlikely to affect local control or survival in this patient cohort, but close follow-up is required. Quality of life may have been affected for four patients who had downgraded or delayed reconstructive procedures.

Published: November 2021

The Covid-19 Pandemic has made economic conditions in Indonesia, including MSME players,
seriously worsened. The government has made many policies to ease the burden on MSMEs, one of
which is providing incentives in the field of taxation. There are still many MSME players who do not
take advantage of the incentives provided. The obstacles they face are the lack of socialization and
their ignorance of using these facilities. For this reason, the community service team of Institut Bisnis
dan Informatika Kwik Kian Gie collaborates with the OperBisnis organization to assist in introducing
simple accounting and utilizing tax incentives for MSMEs during the Covid-19 pandemic. The targets
in this activity are MSME entrepreneurs assisted by the non-profit organization OperBisnis, who
foster more than 50 UMKM entrepreneurs spread across Jabodetabek, Bandung, and Medan. The
solution for MSMEs that have not done bookkeeping is expected to use a single entry system by
recording cash receipts and payments so that they can take advantage of government tax incentives.

Authors: Arquisola Maria Jacinta , Walid Ahlisa Sabiqa Uqda
Published: November 2021

This research aimed to determine whether there is a relationship between employee motivation and learning and development programs at one of Indonesia’s biggest FMCG companies, PT Danone Indonesia. Guided by McClelland’s Theory of Motivation, three independent variables were analyzed relative to learning and development: the need for achievement, the need for power, and the need for affiliation. The research used quantitative method through a survey to gather data from 105 participants working at PT Danone Indonesia who, at the time of the study, had recently joined a series of learning and development programs. Data was analyzed using multiple regressions analysis. Findings show that employees are motivated to undergo learning and development because they want to fulfill two motivational needs: the need for power, and the need for achievement, the former being the highest motivator. On the other hand, the need for affiliation was not a strong motivator to encourage them to learn and develop. Results also show that the interest for learning and development could be explained by 42% of the variables. Implications for research and practice are discussed.

SUPPLAY EKSITASI OUTPUT GENERATOR 300 MW MENGGUNAKAN METODE POLA TITIK DAYA REAKTIF
Authors: Mina Irwan Anto , Sidqi Fahmi Mokh.
Published: November 2021

Excitation system is a system that conducts electric current in the same direction as a generator in a power plant, so that it produces electricity and a large voltage on the increase in the excitation current. In modern regulatory systems, excitation plays an important role in controlling the stability of a development because it involves load fluctuations, so excitation as a controller will require control of the generator output such as voltage, current and power factors in a necessary manner. If the excitation current rises, the reactive power supplied by the system generator will increase otherwise if the reactive power supplied will decrease. If the given excitation current is too small, the reactive power flow will move from the system to the generator so that the generator absorbs the reactive power from the system. This situation is very dangerous because it will cause excessive savings on the stator.

Keywords: Generator, excitation system, transformer, rectifier.

Authors: Zaimar Zaimar
Published: November 2021

This paper presents the effects of the diverse serrated blade configurations on airflow characteristics of a modified centrifugal fan by CFD. This application is investigated to improve aerodynamic performance. These configurations (USB, ISB, USB, OSB) are simulated at the impeller speed levels by CFD. Then tested to analyze airflow characteristic values by ANCOVA test. The simulation results show that the BSB configuration achieves the high static pressures about 84.5-214.7 Pa in the wall zone. While the ISB generates the lower TKE in all the zones, except in the impeller zone. It produces about 0.51-12.47 m2s-2 TKE in the wall zone. The ANCOVA test results indicate that the effects of the impeller speed are very significant (a < 0.01) on the airflow characteristics in all the zones, except for static pressure is no significant (a > 0.05) in the impeller and fluid flow zone. The effect of the serrated blade configurations is very significant on static pressure in the inlet and wall zone, and significant (a < 0.05) in the fluid flow zone. While it is very significant to air velocity in the impeller, fluid flow, and wall zone, and very significant on TKE in the impeller zone and outlet zone.

Alat pengahsil asap cair ini, merupakan pengembangan dari proyek President University sebelumnya, yaitu mesin pembuat arang sekam yang diproduksi dari bahan baku sekam yang kemudian diolah dan menghasilkan briket arang yang bisa dimanfaatkan sebagai bahan bakar alternative pengganti minyak atau gas. Mesin rancangan pertama tersebut kami rasa perlu disempurnakan atau ditindaklanjuti, yaitu dari hanya mesin pembuat arang sekam sekaligus kami kembangkan sebagai pembuat asap cair. Jadi kami mengoptimalkan fungsi mesin tersebut dengan cara melakukan pengembangan dengan memanfaatkan asap hasil dari pembakaran sekam dari mesin pembuat arang sekam menjadi asap cair.

Dalam hal ini penulis fokus pada sistem pendingin mesin asap cair. Sistem pendingin memiliki peranan sangat penting dalam alat penghasil asap cair. Karena system ini akan menentukan optimalisasi dari proses pirolisis yang didalamnya ada proses kondensasi asap mencari cairan. Jadi dalam proses ini terjadi proses perpindahan panas konduksi dan konveksi. Semakin bagus system pendingin yang dirancang, diharapkan menghasilkan hasil produksi yang semakin baik karena kesempurnaan proses kondensasi di kondensor mesin asap cair.

Este artigo buscou entender a situação da pesca profissional e dos pescadores a partir da análise das legislações nacionais que versam sobre a pesca no Brasil. Assim o objetivo foi analisar, em um primeiro momento, a postura do Estado Brasileiro para com esta atividade e, seguidamente, introduzir a temática enfrentada, explicitando a categoria dos pescadores. A metodologia utilizada no presente estudo buscou um enfoque multidisciplinar, baseada em diversos ramos, como por exemplo o direito, a biologia, a antropologia, a engenharia de pesca e outros. Destarte, o estudo apresentou algumas perguntas que foram respondidas ao longo da investigação, como por exemplo: Quais foram as origens da regulamentação das ações de pesca no Brasil? Como era a realidade histórico-social nacional antes do desenvolvimento da indústria da pesca no Brasil? Quando ocorreu a regulação da atividade do pescador equiparada à profissionalização da ocupação? Quando foi criado o primeiro Código de Pesca no país? Como foram as políticas desenvolvimentistas criadas para o crescimento da atividade da pesca no Brasil? Com o desenvolvimento da atividade da pesca houve impacto no tema de proteção do meio ambiente? Como conclusões, o artigo apresentou distintas previsões normativas para a regulamentação da atividade da pesca no país, mas a precária efetivação dessas medidas reforça a ideia que essa prática necessita maiores esforços tanto para a proteção como para a adequação às realidades regionais como, também, no âmbito nacional.

RESUMO: Este artigo tem por objetivo inicial tratar do assédio sexual, com enfoque específico no ambiente de trabalho, fazendo uma investigação sobre a desigualdade de gênero nas relações empregatícias e a íntima conexão que possui com os casos envolvendo assédio sexual. A partir de uma abordagem histórica da visão androcêntrica do mundo, tem-se como objetivo elucidar as dificuldades de inserção da mulher no mercado de trabalho, diante das estruturas patriarcais de poder. Nessa seara, é necessário, analisar, de forma mais íntima, a relação existente entre assédio sexual e discriminação de gênero. No presente estudo, também serão apresentados dados estatísticos recentes que demonstram que o assédio sexual, não raras vezes, acontece devido a questões discriminatórias – principalmente quando provoca reprodução de estereótipos concebidos pela cultura patriarcal. Por fim, será tratado sobre a dificuldade das mulheres em denunciar e posteriormente comprovar suas alegações, tendo em vista os estigmas que sobre elas são colocados, minimizando e culpabilizante a vítima pelo assédio sofrido. No mesmo sentido, encontra-se a dificuldade da prova, tendo em vista que a maioria dos casos de assédio sexual acontecem na clandestinidade, onde, muitas vezes, a maior prova é apenas a palavra da vítima contra a do agressor.

If referring to Article 2 passage (1) of Law No. 37 of 2004 concerning Liquidation and Delay of Obligation Installment Commitments, it is expressed that a debt holder who has at least two lenders and doesn't pay off somewhere around one obligation that is expected and can be If the case alluded to is a sharia monetary chapter 11 case, the court alluded to in this Law is the Strict Court. The exploration technique utilized is standardizing lawful examination. However, along with the growth of ordinary companies and companies that act as financial institutions, both banks and non-banks, the government should respond by providing a special court to resolve commercial cases committed by Islamic companies. Thus, it is necessary that the Commercial Court within the Religious Courts be established in order to fulfill legal certainty, usefulness and elements of justice for corporate legal entities that run their business with sharia principles.
Telaah Yuridis terhadap Pengaturan Restorative Justice di Kepolisian

Police institutions are the first and main gate in law enforcement efforts. First, the police institution in charge of carrying out each criminal case’s enforcement, then the next stage will be determined by the police. The practice of law enforcement so far tends to be retributive justice, so that only a few cases can be resolved in the police investigation process. Restorative justice appears by offering various advantages, including a simple settlement process, involving both parties, both perpetrators and victims, and the role of a third party to mediate, so that cases can be resolved according to the agreement. The police, as the first institution in the law enforcement process, had already issued regulations regarding the application of restorative justice, as a form of law enforcement efforts to change retributive law enforcement. The purpose of this research judicially examined the regulation of restorative justice at the police investigation phase in line with the enactment of the regulation of the Chief of Police Number: SE/8/VII/2018 concerning the Application of Restorative Justice in the Settlement of Criminal Cases and the Regulation of the Chief of the Indonesian Police Number 6 of 2019 concerning Criminal Investigation. This research used a qualitative research method with the type of normative legal research through a statutory approach

A mechanical system, where the load in the form of material point is suspended on inextensible thread screwed on the rotating cylindrical drum, but the drum is connected to the boom rotating around fixed horizontal axis is considered. Using the Lagrange equation of the second kind, a mathematical model of the motion of the mechanical system is obtained. The system has three degrees of freedom, two of which are cylindrical. The investigation of the system motion is carried out using computer technology. As a result, the dependences of linear and angular coordinates and velocities in time at different values of the output data for two main modes of the system operation, namely – under the conditions of lifting and lowering the load are obtained. Appropriate graphs are constructed, including the trajectories of the cargo motion. The mathematical model takes into account nonlinearities of the system and allows you to find the amount of tension of the hoisting rope at any time. The analysis showed that vertical oscillations occur twice as fast as horizontal ones. The phase portrait of the generalized coordinate (angle of the rope with the vertical axis) is the focus, which is untwisted when lifting due to nonlinearity in the system, and when the load moves down, the focus, which twists and approaches the mathematical pendulum is obtained. The obtained results can be used in modeling of controlled pendulum motions for different mechanical systems. The methodology and program are recommended to the students and graduate students in terms of learning the principles of construction and analysis of complex nonlinear dynamical systems.

The assessment of a car fuel efficiency during operation using lubricants (motor and transmission oils) with fullerene compositions in a urban driving cycle is executed. Fullerene compositions were added to the engine and transmission oil at a mass concentration 10%. The guiding document that defines the procedure for testing vehicles for fuel efficiency is GOST 20306-90. Urban driving cycle tests were carried out on a truck ZIL-5301 "Bull" at an outside air temperature of +20°С (summer operation period) and at an outside air temperature of -5°С (winter operation period). It is established that operating a car in the urban driving cycle using of fullerene composition in both engine and transmission oils reduces the fuel consumption of the car by 14.54 ... 17.45% in the summer period. The value of 17.45% corresponds to the mileage of the car without cargo (m = 0), and the value of 14.54% – to the mileage with a cargo (m = 3000 kg). The coefficient of variation of the measured value of fuel consumption was 0.039 ... 0.042. This allows us to conclude that the measurement error is in the range of 3.9 ... 4.2%. When operating the car in the urban driving cycle in the winter operation period, the use of fullerene composition (mass concentration 10%) Simultaneously in the engine oil and transmission oil reduces fuel consumption by 13.24 ... 15.15%. The value of 15.15% corresponds to the mileage of the car without cargo (m = 0), and the value of 13.24% – mileage with cargo (m = 3000 kg). The coefficient of variation of the measured value of fuel consumption was 0.039 ... 0.044. This allows us to conclude that the measurement error is in the range of 3.9 ... 4.4%.
