Makroekonomik dinamikler ülkelerin makroekonomik performansının değerlendirilmesinde baz alınır ve bu değişkenlerin birbirleri ile etkileşim içerisinde olması olasıdır. Bu çalışmada kamu harcamaları ile büyüme, enflasyon, işsizlik ve toplam tasarruflar arasındaki nedensellik ilişkisi incelenmiştir. Bu ilişki Dumitrescu Hurlin Panel Nedensellik Testi ile sınanmış olup bu araştırma için BRICS-T ülkeleri seçilmiştir. Ampirik çalışma neticesinde 1995-2019 yılları arası büyüme ve kamu harcamaları arasında %5 anlam düzeyinde tek yönlü, %10 anlam düzeyinde çift yönlü bir nedensellik ilişkisi tespit edilmiştir. İşsizlik ve kamu harcamaları arasında tek yönlü bir nedensellik bulunmuştur. Enflasyon ile kamu harcamaları arasında istatistiksel olarak bir nedensellik ilişkisi görülmemektedir. Toplam tasarruflar ile kamu harcamaları arasında ise çift yönlü nedensellik ilişkisi saptanmıştır. Kamu harcamaları ile ekonomik büyüme, enflasyon, işsizlik ve toplam tasarruflar gibi değişkenlerin nedensellik ilişkisini tek çalışmada inceleyen sınırlı sayıda araştırma bulunmaktadır. Bu nedenle çalışmanın, göreli kapsamlılığı ve orijinalitesi açısından literatüre katkı sağlaması beklenmektedir.

EXAMINATION OF SCHOOL HEADS' OPINIONS ON LOCALIZATION IN EDUCATION
Authors: Yarım Mehmet Ali
Published: June 2022

In this study, it is aimed to examine the opinions of school principals about decentralization in school administrations. The research is in the qualitative research method. In the research, the phenemology model of qualitative research was used. The study group was selected by purposive sampling method and consists of six school principals experienced in school management. Data were obtained through interview and analyzed by content analysis. According to the results of the research, school principals experience various problems in management, the main ones being pressure from the supervisor, financial inadequacies, personnel shortages and clumsiness and slowness caused by the bureaucratic structure. These problems experienced by school principals are closely related to localization and result from the fact that schools are managed with a centralized structure. School principals believe that decentralization in education is necessary. They think that decentralization in school management will save public money, get rid of the excessive workload of the central government, increase success and efficiency in education, and help ensure adocracy and peace in schools and society. While decentralization has benefits, it can cause some inequalities and negativities. It is recommended to create the necessary environment for this and to make legal and structural preparations.
Whose limit? Water and democracy in a Green Californian Desert
Authors: Müller Birgit , Boutié Elise
Published: June 2022

Groundwater governance in Cuyama Valley, California unites the structural dilemmas of neoliberal environmental governance: a weak state, powerful corporations, a population called to participate but not to decide, and a limited vital resource. Creating institutions of self-governance in the conflictual domain of groundwater use draws local actors into the center of political struggles and strategies, as the State of California avoids governing or limiting groundwater use, purportedly for fear of getting embroiled in costly and lengthy lawsuits with private agroindustry. The SGMA process illustrates the power of property and money in the political game of sustainable resource governance, but it also confronts powerful actors with objectivizing satellite surveys, that point to absolute limits and challenge the growth myth. Institution-building for groundwater governance in Cuyama exposes the strategies of agricultural corporations towards local residents, highlighting the tensions inscribed in the very design of SGMA's polycentric governance structure, between the power to decide and the power to advise. Local residents have appropriated the language of science to contest strategies of denial by the agro-corporations, and to speak reason to unreasonable water users.

Published: June 2022

Purpose: To investigate the metabolic profile and biomarkers of schizophrenia with auditory hallucinations (AHs).
Methods: A total of 18 schizophrenic patients with the symptom of pure AHs (pAHs), 28 without AH (nAHs) and 43 age-matched healthy persons (Con) were enrolled in this study. Participants in pAHs and nAHs groups had relapsed into exacerbations of psychosis after self-discontinuing antipsychotics for at least one month; blood samples were drawn prior to restarting anti-psychotic treatment. Participants with history of recreational substance use were excluded. Positive and Negative Syndrome Scale (PANSS) and Auditory Hallucinations Rating Scale (AHRS) were used to assess the clinical mental state of all samples. Enzyme-linked immunosorbent assay (ELISA) was used to estimate the level of cytokines, and metabolomics analysis to identify potential biomarkers and pathways in the three groups. Graphpad 8.0 software was used to calculate the area under the receiver operating characteristic (ROC) curve. The relationship between metabolites and cytokines were determined using correlation analysis.
Results: Questionnaire scores showed significant differences in the positive symptom scale and PANSS total between nAHs and pAHs groups. Four cytokines (BDNF, IL-2, NGF-β and TNF-α) differed significantly among the three groups. Six molecules in the nAHs group (phenylalanine, hippurate, serine, glutamate, valine and cystine) and four in the pAHs group (phenylalanine, serine, glutamate and cystine) were identified as potential biomarkers. In addition, phenylalanine was shown as a potential independent diagnostic biomarker for pAHs. Correlation analysis revealed that cystine and serine were significantly negatively correlated with IL-2 in the pAHs group.
Conclusions: This study revealed the metabolic profile of patients with schizophrenia with AHs and provided new information to support the diagnosis. The identification of unique biomarkers would contribute to objective and reliable diagnoses of patients with schizophrenia with AH.
Estimating Disease Prevalence in Administrative Data
Authors: Kopec Jacek A.
Published: June 2022

Purpose: Disease prevalence estimates from population-based administrative databases are often biased due to measurement (misclassification) errors. The purpose of this article is to review the methodology for estimating disease prevalence in administrative data, with a focus on bias correction.
Source: Several approaches to bias correction in administrative data were reviewed and application of these methods was demonstrated using an example from the literature: physician claims and hospitalization data were employed to estimate diabetes prevalence in Ontario, Canada.
Findings: Misclassification bias in prevalence estimates from administrative data can be reduced by developing and selecting an optimal algorithm for case identification, applying a bias correction formula, or using statistical modelling. An algorithm for which sensitivity equals positive predictive value provides an unbiased estimate of prevalence. Bias reduction methods generally require information about the measurement properties of the algorithm, such as sensitivity, specificity, or predictive value. These properties depend on disease type, prevalence, algorithm definition (including the observation window), and may vary by population and time. Prevalence estimates can be improved by applying multivariable disease prediction models.
Conclusion: Frequency of a positive case identification algorithm in administrative data is generally not equivalent to disease prevalence. Although prevalence estimates can be corrected for bias using known measurement properties of the algorithm, these properties may be difficult to estimate accurately; therefore, disease prevalence estimates based on administrative data must be treated with caution.

Authors: Cheng Lin , Zhao Yun , Ke Hong
Published: June 2022

Purpose: Through comprehensive bioinformatics analysis based on the immune microenvironment, this study aimed to identify immune-related RNA biomarkers that indicate aneurysmal subarachnoid hemorrhage (aSAH).
Methods: The GSE73378 dataset was downloaded from the National Center for Biotechnology Information GEO database, providing blood from 107 normal controls and 103 patients with aSAH. The immune infiltration types in the aSAH blood samples were assessed and RNAs that were differentially expressed (DE) between 1) the aSAH and control groups and 2) the immune infiltration groups (high and low) were identified. The intersecting genes were subjected to weighted gene co-expression network analysis followed by co-expression network construction. The aSAH-related genes and pathways were identified from the Comparative Toxicogenomics Database: update 2019.
Results: A total of three DE long non-coding RNAs (lncRNAs) and 301 DE mRNAs were identified. Of the 301 mRNAs, 91 were significantly enriched in three modules. Based on the 91 mRNAs and three lncRNAs, a co-expression network related to the disease pathway was constructed. This pathway consisted of 16 factors, including the 13 mRNAs (e.g., TNFSF13B, TNFSF10, MYD88, GNA12 and NSMAF) and three lncRNAs (FAM66A, LINC00954 and CELF2-AS2), as well as six pathways, including the NF-κB, toll-like receptor, and sphingolipid signalling pathways.
Conclusion: TNFSF13B, MYD88, GNA12, NSMAF, FAM66A, LINC00954 and CELF2-AS2 may serve as biomarkers for aSAH. The NF-κB, toll-like receptor and sphingolipid signalling pathways may play critical roles in the progression of aSAH.

Published: June 2022

The present study is about an experimental investigation of the strength and response of reinforced concrete tapered beams strengthened by near surface mounting (NSM)-CFRP technique. The influence of several parameters on the behavior of beams is investigated. And those parameters are: angle of inclination and strengthening patterns by NSM-CFRP technique. The experimental program involved testing nine specimens of reinforced concrete tapered beams and one prismatic beam. There were two groups in the experimental program; the first group included four unstrengthening reference beams to investigate the effect the angle of inclination, and the second group included six specimens were strengthened by NSM-CFRP strips with different strengthening patterns (U-strips) and (UL-strips) were used to strengthen the tapered beams against shear and flexural forces. The results of the experiments indicated that as the angle of inclination increased, from (0˚) to (7°), (14°) and (21°) decreases the ultimate load capacity (Pu) by about (4)%, (14)% and (41)% respectively for unstrengthen tapered beams, as well as the deflection at the ultimate load. Also, when compared unstrengthen with strengthened beams, the ultimate load capacity will increase with the angle of inclination increased, from (0˚) to (7°), (14°) and (21°), for (U-strips) patterns the percentages of increase were (7)%, (9)% and (33) % respectively, while (UL-strips) increased the ultimate load capacity by about (19)%, (19)% and (44)% respectively.

Published: June 2022

The purpose of this study is to examine the tasks in the 5th and 6th grade of the 2015 elementary English textbooks in terms of task design standard and core competency development, investigating the effectiveness and improvement of textbook tasks. For these purposes, in this study, a task analysis checklist reflecting four competencies and their sub-factors was developed to analyze 397 tasks of 5 types, 10 English textbooks for fifth and sixth graders. As a result, it was confirmed that the distribution of tasks and the number of tasks among the five textbooks were relatively evenly arranged except for one textbook. It was also found that the selected tasks for each textbook included all four core competencies, but knowledge information processing competency was found to be very low in all textbooks compared to the other three competencies. As a result of the analysis of the distribution of sub-factors by core competency, it was found that all four competency task activities were concentrated on specific sub-factor activities, indicating that there was an imbalance between the sub-factors of competency.

Authors:   The Korea Association Of Primary English Education, Chung Ha Nul , Park Young Ye
Published: June 2022

The purpose of this study was to analyze video dubbing effects on speaking elements of English and affective areas of 4th grade elementary English learners.
Twenty students participated in the activity of dubbing five videoclips selected from a dubbing application called 2DUB. The conclusions are as follows. First, learning by video dubbing had a positive effect on the improvement of pronunciation and suprasegmental phonemes required for the speaking ability, because significant improvements were found in all areas of pronunciation, stress, rhythm, and intonation. In particular, it could be a more effective learning method for students of low to intermediate ability than for those of higher ability. It also had a positive effect on both male and female students in improving pronunciation and rhythm. Second, it had a positive effect on interest and anxiety among the affective areas. In particular, male students showed a significant reduction in anxiety which means learning by video dubbing can not only be an effective way to induce interest in learning English but can also be usefully used to lower male students’ anxiety toward learning English. Based on these conclusions, important implications and suggestions were included.

Authors:   The Korea Association Of Primary English Education, Kim Sung Hye , Kwon Suh Keong
Published: June 2022

This study explored teachers’ perceptions of the operation of elementary school basic English programs. Basic English programs have been implemented as an important component of the elementary English enhancement policy. This study investigated the teachers’ satisfaction level and the effectiveness of the basic English programs to understand the current situation and evaluate the effectiveness of the policy. The findings showed that teachers mainly utilized the “system for the diagnosis and learning support of basic English ability” when diagnosing students’ English achievement levels. Furthermore, most teachers showed positive perceptions about the level of infrastructure and program operation, but this varied by the size of the region. The effect of basic English programs for improving students’ interest in English and self-directed learning ability was relatively lower in the schools in rural areas than in large cities.
Lastly, the majority of teachers demanded support for more teaching and learning materials and program management. This paper concludes by asserting the need for sophisticated support for basic English education at elementary schools, focusing more carefully on the circumstances of the size of the region.

Published: June 2022

Resistant starch has been shown to be associated with many health benefits. The study
was conducted to analyze amylose and resistant starch content in selected starchy
materials (black beans, red beans, green Xiem bananas, and potatoes) and investigate the
influence of their flour/starch mixing ratio on the quality of noodles. The microstructure of
noodles was analyzed by scanning electron microscopy. The results showed that potato
starch had the highest resistant starch content (56.70%), followed by green Xiem banana
flour (41.55%), black bean flour (16.51%), and red bean flour (15.55%). The raw
materials with higher resistant starch also had higher amylose content. Amylose content,
resistant starch content, and hardness of noodles increased when partly replacing wheat
flour with the high level of RS flours/starches in the formulation. The data rank some tests
revealed that formula A3 (replacing 50% of wheat flour with other starchy food
containing high levels of resistant starch) was chosen due to the product containing
relatively high RS content (14.78%), well structured and well accepted by panellists. The
texture of the cooked noodles was assessed to be similar to that of the control sample
(100% wheat flour). This study proved that it is possible to elaborate noodles to replace a
part of wheat flour with starchy food containing high levels of the well-accepted
formulation.

The potential health benefits of native and exotic fruits have been the subject of many
recent studies in the Philippines as fruits are chief sources of biologically active
substances such as polyphenols, carotenoids, anthocyanins and flavonoids. Dragon fruit
(Hylocereus spp.), an exotic fruit originating from South America, has become
increasingly popular in the Philippines these past few years. Relatively new to the country,
its full health benefits are yet to be discovered. In this study, the anti-tyrosinase and
antioxidant activities of the methanolic and aqueous extracts of the flesh and peel of red
and white dragon fruits were evaluated while the anti-angiogenic potential of the ethanolic
and aqueous extracts of the flesh and peel of white dragon fruit were screened using the
duck embryo chorioallantoic membrane (CAM) assay. The methanolic extract of the red
dragon fruit peel showed potent inhibition against the diphenolase activity with the
percentage of inhibition being significantly higher than that of Rutin at 20 mg/mL.
Furthermore, it exhibited better antioxidant activity than ascorbic acid in the radical
scavenging assay as well as the ability to chelate with ferrous ions and reduce the ferric
ion. The observed activities may be attributed to its high total phenolic content and the
observed presence of tannins. In CAM assay, treated duck embryo showed evident
suppression of veins at increasing concentrations of ethanolic and aqueous extracts of the
white dragon fruit flesh and the aqueous extract of the white dragon fruit peel (250 ppm to
2000 ppm), with almost no vascularization at 2000 ppm; the trends of vascularization
were almost comparable to that of quercetin, a known anti-angiogenic compound. These
results contribute to the increasing repertoire of potential health benefits of dragon fruit.
Effect of conventional and ultrasonic-assisted extracts on betacyanin content of
red dragon fruit (Hylocereus polyrhizus)
Authors: Thuy N.M. , Ngoc P.T.B. , Tai N.V.
Published: June 2022

The red dragon fruit (Hylocereus polyrhizus), an available and popular agricultural source
in Vietnam, is potential material for food colourants because of the presence of
betacyanin. For the purpose of using dragon fruit extract to add colour to processed foods,
the study on the effects of extraction methods (conventional and ultrasound-assisted) on
the flesh and peel of the fruit was carried out using water as an extraction solvent. The
obtained results showed that using ultrasonic waves in extraction enhanced the total
betacyanin content in red dragon flesh and peel extract. Multiple regression analysis for
betacyanin and the independent variable was obtained with a high coefficient
determination (R2
>0.8). The highest total betacyanin content predicted by the models were
27.49 mg/100 mL and 22.28 mg/100 mL corresponding to extracted at a ratio of 83.74%
red dragon flesh for 13.15 mins and the ratio of peel to the water of 90.63:9.37 for 12.91
mins. The obtained result could be applied to the food industry to use the achieved as a
natural food colour for further processing.
The Impact of Capital Structure and Ownership Structure on Financial Performance: A Study on the KSE 100 Listed Firms in the Pakistan Stock Exchange
Authors: Shah Jamal , Ahmed Jameel , Khan Nadir
Published: June 2022

Purpose: This research study aimed to examine the impact of capital structure and ownership structure on the financial performance of KSE-100 index firms on the Pakistan Stock Exchange.

Design/Methodology/Approach: 100 listed companies have been selected as sample for the study but due to data limitations, 90 companies' annual data has been used for 2009-2018. Ordinary least square regression was used on the panel data for analysis. Two measures of capital structure (debt-to-equity ratio and debt to total assets) while three measures of ownership structure (Foreign ownership, Institutional ownership, and managerial ownership) have been used to determine their impact on three financial performance measures (return on assets, return on equity, and Tobin's).

 Findings: The results of this study showed that there is a significant negative relationship between financial performance and capital structure. Ownership structure and firm financial performance showed a significant positive relationship when measured on the basis of foreign ownership and institutional ownership while insignificant and negatively related to managerial ownership.

Implications: This study suggests that organizations should take financing decisions in accordance with optimum capital structure because more debt decreases financial performance. Furthermore, a decision should be taken the encouragement of foreign and institutional shareholding, while the level of managerial ownership should be lessened to enhance financial performance

Published: June 2022

Purpose: This study is an effort to depict the level of satisfaction in children with vision impairment and their parents about instructional practices and educational provisions available at primary level in Government Special Education Institutions of Punjab, Pakistan.

Design/Methodology/Approach: It was a descriptive mixed method research. Multistage sampling technique was applied to collect the data from randomly selected 31 parents and 53 students with vision impairment studying in fifth grade. Three institutions were randomly selected from each zone to conduct the structured interviews from parents while four special education institutions were chosen randomly from each zone to fill the questionnaires by all available CWVI studying at primary level.

Findings: The study reported that the majority of parents are belonging to low socio economic status and they have minimum level of education and awareness and as do CWVI. Teachers usually have good attitude with parents. School management gave stipend, uniform and shoes in time. In addition CWVI praised the instructional practices of their teachers in reading, writing, mathematics, assigning & checking homework, regular class tests and provision of result cards to their parents. But they had reservations due to lack of training in orientation and mobility, absence of training in vocational skills and lack of in time availability of Braille books

Implications/Originality/Value: Study recommended that various programs and seminars should be arranged for parents to get better understanding of the standards of instructional practices and educational provisions.  Braille books and Braille equipments should be provided to CWVI. Sufficient training about orientation and mobility, vocational subjects and use of assistive devices/IT should be provided to students in all special education institutions.

Published: June 2022

Products based on silicon carbide are widely used in different industrial applications due to a high level of their mechanical, thermal, and operational properties. When the reaction sintering procedure is used to obtain silicon carbide materials, the preformed porous samples consisting of silicon carbide powders, carbon filler, and coke binder are subjected to liquid-phase silicizing (silicon melt infiltration (MI) in a vacuum furnace. We present the results of studying samples of reaction-bonded silicon carbide (RBSC) using visual-optical and radiographic methods of non-destructive control. Silicizing of carbon-silicon carbide materials can result in formation of defects on their surface and in the bulk of the material. The visual-optical method is shown to be rather simple and extremely informative procedure which ensures the detection of surface defects in the form of pores, cracks, chips, shells, and can also provide indirect indications of possible presence of internal defects in the form of underimpregnated areas. The samples silicized with a larger number of silicon drops on their surface exhibit a higher density and a smaller number of underimpregnated areas which can be detected using radiographic control. X-ray control carried out for several exposures differing in the angle of sample rotation by 90° provided 95%-probability of detecting internal volumetric and planar defects. The results obtained can be used in the manufacture of RBSC-based parts of tribotechnical duty, shut-off valves and other wear-resistant products.
Simulation of the deformation diagram of a viscoelastic material based on a structural model
Authors: Kurkin A. S. , Kiselev A. S. , Krasheninnikov S. V. , Bogdanov A. A.
Published: June 2022

A serious problem in computer simulation of the stress state of polymer structures is to ensure the adequacy of the mathematical description of the mechanical properties of materials. The structural model of a viscoelastic material has a number of advantages in describing both the rheology of the material and trajectories of the material deformation. In this model, the material is described as a structure consisting of several elements with relatively simple rheological properties. Reproduction of a complex behavior of the material under alternating non-isothermal loading is ensured through the interaction of simple elements. A technique developed for modeling a viscoelastic material is intended for strength calculations of structures made of materials operating under conditions of prolonged repeated thermomechanical exposure using the finite element method. Application of the developed procedure to a polymeric material, polymethyl methacrylate (PMMA), is considered. The results of testing the material under uniaxial compression at a constant temperature are presented. The methodology and results of identification of the developed structural model using a specialized software are described. Formulas for approximation of the deformation characteristics of the material at a constant deformation rate and the time dependence of material deformation during the holding the material at a constant stress level are obtained. Approximation is an important step in identification of the material model which facilitates the systematization of the initial experimental data and their further mathematical processing. The best approximation of the deformation characteristics of a viscoelastic material is given by a hyperbolic tangent function, whereas the logarithmic function provides the best results for deformation upon exposure. Further construction of the structural model was carried out by selection of sequential parameters of bilinear rheological functions of the individual elements the model and iterative refinement of those parameters. The simulation results were compared with the experiments carried out at different strain rates and with exposure at different stress levels. We just present the results of the initial stage of the carried out experimental and theoretical studies.
A technique for experimental determination of the resistance of materials to plastic shear upon their processing by cutting

Theoretical or theoretical-experimental methods are widely used when studying various techniques for processing materials, cutting among them. The physical and mechanical properties of the materials being processed are to be taken into account along with the process parameters (mode, geometric parameters of the machining tool, etc.). The resistance of the material to plastic shear present in the calculated dependences for determination of the force and temperature in the cutting zone and the temperature in the surface layer of the workpiece, as well as for determination of the quality parameters of the surface layer of the part (the residual stresses, degree and depth of work hardening, roughness, and others) and the accuracy of processing is used in all the aforementioned methods in addition to the ultimate tensile strength and the modulus of elasticity of the processed material. Previously, when determining the numerical value of the resistance of the processed material to plastic shear, the latter was considered as a function of the tensile strength of the processed material. However, an increased temperature observed in the cutting area which depends on the combination of the processed and tool materials, the mode of processing, and on the geometry of the cutting part of the tool was not taken into account. The value of the effective cutting force was also ignored though this value is determined by the same parameters which determine the temperature in the cutting zone. The mechanical characteristics of the processed material are known to depend on the temperature. In this regard, the resistance of the processed material to plastic shear was assessed at a certain temperature determined by the technological conditions of processing. The goal of the study is to prove the necessity of determining the resistance of the processed material to plastic shear to be used in theoretical determination of cutting forces, temperature in the cutting zone, and the quality parameters of the surface layer of the part. The dependence is given to determine the value of the resistance of the processed material to plastic shear under optimal processing conditions that ensure the minimum wear of the cutting tool taking into account the parameters of the cutting process and the geometry of the cutting part of the tool. Processing conditions that determine the temperature and force in the cutting zone are taken into account by chip shrinkage in the formula for determining the value of the resistance of the processed material to plastic shear. The use of the proposed technique can improve the accuracy of calculations of the quality parameters of the material of the surface layer of the part and the accuracy of processing.

Pada masa  Corona Virus Dieases-19 (Covid-19) melanda Indonesia, terdapat beberapa sektor baik esensial maupun kritikal melakukan transformasi secara teknikal di lapangan secara digitalisasi. Digitalisasi berhubungan dengan Teknologi Informasi yang merupakan suatu teknik untuk mengumpulkan, menyiapkan, menyimpan, memproses,mengumumkan, menganalisis dan/atau menyebarkan informasi menurut Pasal 1 angka 2 Peraturan Otoritas Jasa Keuangan Nomor 12/POJK.03/2018 tentang Penyelenggaraan Layanan Perbankan Digital oleh Bank Umum. Sebelum Covid-19 melanda Indonesia, sudah dilakukan sosialisasi atas transformasi perbankan secara konvensional menuju digitalisasi yang diakibatkan dorongan melalui perubahan Revolusi Industri 4.0 yang menginisiasikan teknologi sebagai alat bantu hidup masyarakat sehari-hari. Penelitian ini menggunakan metode Normatif Yuridis (doctrinal research) dimana akan dilakukan secara pendekatan peraturan perundang-undangan (statue approach),  pendekatan kasus (case approach) dan pendekatan analisis (conceptual approach). Namun, penguatan digitalisasi pada perbankan merupakan suatu dorongan terhadap ekonomi bangsa secara e-economy yang telah diinisiasikan dalam 5 (lima) tahun kebelakang. Tentunya dengan adanya momentum pandemi Covid-19 akan menjadi sisi positif terhadap efisiensi dan efektivitas terkait penyaluran modal serta peningkatan kepuasaan melalui metode costumer service digital fully kepada masyarakat yang tentunya sistem perbankan digitalisasi dapat membantu pertumbuhan ekonomi nasional pada masa Covid-19 ini
Pengaturan E-Court Dalam Peraturan Perundang-Undangan Untuk Penyelesaian Perkara Perdata di Pengadilan

Penyelesaian perkara perdata di Pengadilan Negeri selama ini dilakukan secara manual atau konvensional, yaitu proses penyelesaian perkara perdata yang dilakukan secara bertemu langsung atau tatap muka antara para pihak (penggugat dan tergugat), penerima kuasa (advokat), panitera pengganti dan hakim pemeriksa perkara di ruang sidang pengadilan. Namun, sejak diberlakukannya Peraturan Mahkamah Agung Republik Indonesia Nomor 3 Tahun 2018 tentang Administrasi Perkara di Pengadilan secara elektronik, yang telah diubah dengan Peraturan Mahkamah Agung Nomor 1 Tahun 2019, Indonesia sudah menuju kepada Peradilan modern yang menerapkan atau melaksanakan penyelesaian perkara di Pengadilan, baik mengenai administrasi perkara, maupun persidangannya dilaksanakan secara elektronik (e-court). Isu hukum dalam penelitian ini adalah Konsep Pengaturan E-Court untuk Penyelesaian Perkara Perdata di Pengadilan pada masa yang akan datang, dengan menggunakan metode penelitian hukum normatif dengan menggunakan metode deduktif. Hasil Penelitian menyimpulkan bahwa, Pengaturan E-Court dalam Penyelesaian Perkara Perdata di Pengadilan pada masa yang akan datang harus diformulasikan atau dirumuskan dalam jenis Undang-Undang dan disatukan dengan peraturan yang mengatur tentang Hukum Acara Perdata (Kitab Undang-Undang Hukum Acara Perdata) pengganti HIR/RBg kemudian Perumusan E-Court pada Kitab Undang-Undang Hukum Acara Perdata tersebut dimasukkan atau dimuat  dalam materi pemeriksaan perkara di persidangan. Apabila Peraturan yang mengatur tentang e-court tersebut diatur dalam jenis Undang-Undang yang dibentuk oleh legislatif, maka ketentuan tersebut bersifat imperatif/memaksa, mengandung perintah dan larangan serta mengikat secara umum yang wajib dilakukan oleh setiap warga negara, dalam hal ini termasuk para pihak yang berperkara. Sedangkan dibentuknya Peraturan Mahkamah Agung oleh Mahkamah Agung dimaksudkan untuk mengatur hal-hal yang berkaitan dengan kelancaran pelaksanaan tugas dan wewenang Mahkamah Agung sebagai Pengadilan tertinggi.
Pembatasan HAM dengan Alasan Public Health Emergency dalam Hukum HAM dan Hukum Pidana Indonesia

Published: June 2022

Konsep “limitation” dapat ditemukan dalam beberapa instrumen hukum hak asasi manusia internasional demikian juga dalam hukum HAM di Indonesia. Konsep ini dapat diterapkan dalam beberapa situasi termasuk dalam keadaan public health emergency. Keadaan saat ini dengan adanya pandemic Covid-19 memaksa negara untuk melakukan pembatasan terhadap hak individu di dalam yurisdiksinya. Hal ini sejalan dengan konsep PHEIC yang beberapa saat lalu diumumkan oleh WHO. Namun demikian bagaimana mekanisme implementasi di lapangan menjadi persoalan lain yang perlu dilakukan penelitian lebih lanjut. Di Indonesia implementasi dari Public Health Emergency of International Concern (PHEIC) adalah limitasi dalam bentuk Pembatasan Sosial Berskala Besar (PSBB) sebagaimana diatur dalam Undang-Undang Karantina kesehatan. Namun demikian, dalam implementasinya di lapangan seringkali PSBB dijadikan sebagai alasan oleh aparat kepolisian untuk dilakukannya mekanisme pidana seperti penahanan terhadap para pelanggar PSBB. Oleh karena itu dalam penelitian ini akan dibahas lebih lanjut tentang apakah Public Health Emergency sebagaimana dikemukakan oleh (World Health Organization) WHO dapat menjadi dasar Pembatasan HAM oleh Pemerintah Indonesia dan apa konsep dan mekanisme yang dapat ditawarkan dalam penerapan pembatasan HAM melalui PSBB ini baik dalam sistem hukum HAM maupun dalam sistem hukum Pidana di Indonesia

Apart from Father, there are Mother, Son, Daughter, Fiancee, Neighbor, Woman in Pomegranate Flower Dress, Young Man, Doctor, Butler, Servant. The Father's bond with memories is stronger than with reality. For this reason, the game has been analyzed in the context of memories. The father is a person who has entered the path of old age. He took refuge in his memories because he was not satisfied with the life he lived. At the center of her memories is the Woman in Pomegranate Flower Dress. He connects to the past and life with his portrait in the painting. The Woman Dressed in Pomegranate Flower points to thirty-five years ago. The woman still stands in the painting as a young and beautiful young girl. In fact, the Father is also in the past. Because the Woman Dressed in Pomegranate Flower is to represent the love that was left incomplete. It is in vain that he tries to fill this deficiency with the memory of the woman. The object of desire that creates the deficiency is the woman herself. In this respect, the painting with the portrait of the Woman Dressed in the Pomegranate Flower is not an object. Table; It is like a living being that comes between Father and Mother, Son and Daughter. It is the unforgettable memory that makes the house uncanny.
