ABSTRACT            Capital market practices in the type of stock instruments undergo a shift in the way of analysis. This is not in line with the theory of stock fundamental analysis which explains that fundamental factors become the main variable in determining stock investment decisions for the long term. Fundamental analysis of stocks takes into account various factors including company performance, macroeconomic analysis and the industrial sector. The fundamental variable of stock analysis is used as a consideration of the investment portfolio of the stock for the long term. Users of these variables are usually the owners of capital with the type of investor. Investor type is the owner of capital with the main purpose of buying shares by expecting stock valuations in the long run and dividends, not short-term capital gains. The need for the development of applied science of technical analysis and fundamental analysis of stock investors who have a form of trading activities on a daily basis generally only conduct transactions on the capital market using speculation from each investor. This of course in terms of education that novice stock investors do must have the same time in obtaining maximum income in the trading stock market            This service is carried out on customers of PT Reliance Surakarta. There were 13 training participants, namely customers who became stock investors but did not trade every day for a short period of time. The service was held for 1 day. Expected outputs from the event are expected that after attending the training the participants are expected to be able to carry out fundamental and technical analysis of JCI fluctuations on a daily basisKeywords: Stock index, JCI Fluctuation Prediction, Swinger Type
PENDAMPINGAN PENGGUNAAN INTERNET BAGI IBU-IBU PKK DI DESA NGASINAN ETAN, GEBANG, MASARAN, SRAGEN

Published: January 2021

AbstrakSebagai dampak dari perkembangan dunia teknologi informasi, internet menjadi primadona baru dalam komunikasi antar manusia. Tak dapat dipungkiri, dalam waktu yang tidak terlalu lama, kehadiran internet menggantikan berbagai media komunikasi dan informasi yang ada. Hal ini terjadi karena internet dipandang lebih efisien dan efektif bagi dunia kerja khususnya berkaitan dengan komunikasi dan informasi. Namun tak dapat dipungkiri, walau banyak manfaat yang diberikan, sebagai produk teknologi, internet juga menghadirkan dampak negatif bagi penggunanya. Mulai penipuan melalui bisnis online, pembajakan situs atau account (hacking), penyalahgunaan situs jejaring sosial seperti facebook hingga “Jutaan” materi tidak pantas dalam bentuk film, foto dan tulisan menjadi dampak negatif bagi pengguna internet. Tak terkecuali ibu-ibu rumah tangga, dampak negatif yang berorientasi pada pornografi membawa kekuatiran tersendiri bagi mereka. Kekuatiran ini membuat mereka memiliki pandangan bahwa idealnya internet tidak digunakan oleh keluarga mereka. Pandangan ini menjadi begitu ekstrim hingga mereka memberikan paparan yang salah mengenai internet kepada putra-putri mereka.Sikap ini tentu merugikan, sebab dengan ketertutupan terhadap dunia internet, ibu rumah tangga dan keluarga terutama putra-putri mereka akan kehilangan kesempatan untuk memperoleh manfaat yang disediakan oleh internet. Pengetahuan, relasi bahkan bisnis yang menghasilkan uang maupun pertumbuhan iman melalui berbagai situs religious tidak akan mereka dapatkan dengan adanya sikap ini.Namun sikap tersebut tak dapat disalahkan sepenuhnya, dengan adanya berbagai dampak negatif yang ditimbulkan oleh “dunia maya” ini, sehingga peran ibu rumah tangga sangat penting dalam mengarahkan anak menjadi calon pemimpin masa depan. Oleh karena itu kegiatan Pengabdian Kepada Masyarakat ini dilakukan untuk mendampingi ibu-ibu PKK mengetahui fasilitas-fasilitas yang terdapat pada internet, serta mengetahui dampak negatif dan positif perkembangan internet bagi putra putrinya. Setelah dilakukan pendampingan Ibu-ibu PKK mampu menggunakan internet dan dapat mengontrol kegiatan putra putrinya.Kata Kunci : Internet, Ibu-Ibu PKK, Desa Ngasinan Etan

Time-dependent Pancharatnam phases and quantum correlations for coupling superconducting two-qubit system with dissipative environment
Authors: Liyuan Xue  , Z.S. Wang
Published: January 2021

Two coupling superconducting qubits are studied for the quantum concurrence, discord, and Pancharatnam phase, for the X and Y states under the dephasing and instantaneous decay environment as well as their couplings. We find that the X and Y states are special mixed states according to the Bloch radius. In general, the larger the environment and phonon number are at the larger region of time, the larger the quantum concurrence and discord are. But we find that the environment correlations are helpful to implement the quantum computation. The Pancharatnam phases provide a way to distinguish the X and Y states.

Published: January 2021

Enhancing image brightness under low light conditions is crucial. The traditional night vision technology depends on the development of photoelectric materials and accurate image processing algorithms. Inspired by the structure of elephant-nose fish, we construct a bionic image intensifier (BII) model. The BII is a planar array based on the concentrating principle of the compound parabolic concentrator (CPC). This solution is based on pure optical design and independent. Through light tracing, the simulation results show that the brightness of the image is improved and good image uniformity is obtained. Quantitative analysis of the geometric concentration ratio (GCR) and the image uniformity is used to optimize CPC structure parameters. At the same time, we also discuss the influence of CPC structural parameters on image continuity, uniformity and geometric concentration ratio. The optimization results are as follows: the input port diameter is 50 μm, the output port diameter is 10 μm, the height is 90 μm, the GCR is 5.61, and the image uniformity is 95.30%. The comprehensive performance of the BII achieves the best.
Optical coherence tomography image for automatic classification of diabetic macular edema
Authors: Ping Wang  , Jia-Li Li  , Hao Ding
Published: January 2021

Diabetic macular edema (DME) is the dominant reason of diabetic visual loss, so early detection and treatment of DME is of great significance for the treatment of diabetes. Based on transfer learning, an automatic classification method is proposed to distinguish DME images from normal images in optical coherence tomography (OCT) retinal fundus images. Features of the DME are automatically identified and extracted by the pre-trained convolutional neural network (CNN), which only involves fine-tuning the VGGNet-16 network without any user intervention. An accuracy of 97.9% and a sensitivity of 98.0% are acquired with the OCT images in the Duke data set from experimental results. The proposed method, a core part of an automated diagnosis system of the DME, revealed the ability of fine-tuning models to train non-medical images, allowing them can be classified with limited training data. Moreover, it can be developed to assist early diagnosis of the disease, effectively delaying (or avoiding) the progression of the disease, consequently.
Optimization of technology of diode laser mirror processing to maximize the threshold of catastrophic optical degradation
Authors: Dąbrowska Elżbieta , Teodorczyk Marian , Szymański Michał , Maląg Andrzej
Published: January 2021

In this paper, optimization works on the technology of passivation and optical coatings of laser diode facets are described. The main goal is to increase the optical power at which the catastrophic optical mirror damage occurs. The coatings and passivation processes have been done in an ion source-aided electron-beam evaporator. The essence of passivation was to remove native oxides and produce a native thin nitride layer with simultaneous saturation of the dangling atomic bonds. The procedure has been realized with the help of nitrogen or forming gas (N2 + H2) beam. As a result, we present sets of technological parameters allowing to increase the catastrophic optical mirror damage threshold of diode lasers.
Prolegomena zu einer Globalgeschichte als Wahrnehmungsgeschichte

Die Praxis, Globalhistoriografie auf die Beschreibung bestimmter Abläufe in der kurzen Zeitspanne des späteren 18., 19. und 20. Jahrhunderts einzuengen,1 hat zum Aufkommen des Paradoxons beigetragen, dass Globalhistoriografie zwar den Prozess der Globalisierung
thematisiert, aber die Globalisierung des europäischen Weltbilds im Sinn der Genese der Wahrnehmung der Oberfläche des Planeten Erde als Gemengelage von Land und Wasser, wie sie jüngst in der Perspektive der Internationalen Raumstation (ISS) aufscheint, und den Oktroi dieses
Weltbilds in anderen Teilen der Welt schlechthin ignoriert hat.2 Die Einengung der Globalhistoriografie auf die Zeit seit der Wende zum 19. Jahrhundert ist folglich kontraproduktiv gewesen. Denn sie bedingte den Verzicht auf Untersuchung, Beschreibung und Erklärung genau derjenigen
Wandlungen, die die europäische Weltwahrnehmung als Spezifikum des Gegenstands dieser Forschungsrichtung erst entstehen ließen.

Objective: to summarize the experience of treatment patients with resistant forms of gestational trophoblastic neoplasia (GTN). Materials and methods: results of treatment of 15 patients with resistant forms of GTN treated in the N.N. Petrov Research Institute of Oncology through the period 01.01.10-12.11.19 were analyzed. Results: In three out of the 15 patients the tumor was initially characterized as the low-risk (3/15, 20%), the remaining 12 women were from the high-risk group (12/15, 80%). Four out of 12 high-risk patients were ultra-high risk (> 12 points according to the FIGO classification). In low-risk patients with resistant GTN forms EMA-CO therapy proved to be effective as the second line chemotherapy. In eight high-risk patients the combined treatment included the surgical component (hysterectomy in 3 cases, thoracotomy with metastasectomy in 3 cases, hysterotomy with excision of the tumor in 1 case, excision of the tumor from the abdominal wall - in 1 case). In three cases of ultra-high risk GTN, the EMA-EP chemotherapy proved effectiveness, in one of them - without a combination with surgical treatment. Combined treatment was performed in two other cases: in one case with chemotherapy was followed by thoracotomy, metastasectomy, in another - by a gamma knife radiotherapy of brain metastasis. Conclusion: even in cases of low-risk GTN careful monitoring of patients is required, despite adequate treatment among resistant forms. After the failure of methotrexate monochemotherapy with low-risk GTN patients can be successfully treated with EMA-CO chemotherapy. Only rare histological forms (epithelioid trophoblastic tumor, placental site trophoblastic tumor) are not sensitive to drug therapy and require surgical treatment. In cases of ultrahigh-risk GTN with resistance to 1st-line chemotherapy an EMA-EP regimen is effective with or without surgical intervention. Residual “tumor nodes” after completion of treatment and normalization of the HCG level do not always require surgical removal, their dynamic observation is possible, because according to the results of observations, when they were nevertheless excised, no histologically viable tumor tissue was found.
Glauconitic deposits at Julegård on the south coast of Bornholm, Denmark dated to the Cambrian
Authors: Clemmensen Lars B. , Bromley Richard G. , Holm Paul Martin
Published: January 2021

Bioturbated, glauconitic siltstones and sandstones are overlain by presumed Upper Triassic deposits at coastal exposures at Julegård on the south coast of Bornholm. These glauconitic deposits have not previously been dated. A 40Ar-39Ar dating of the glaucony gives an age of 493 ± 2 Ma suggesting the deposits belong to the Lower Cambrian Norretorp Member of the Læså Formation.

The shallow marine deposits are strongly bioturbated, but only a single ichnoassociation is represented. The ichnogenus is referable to either Trichophycus Miller and Dyer, 1878 or Teichichnus Seilacher, 1955. Rare examples of Rusophycus Hall, 1852, probably trilobite trace fossils, are also represented.
The petrology and provenance of coal artifacts from Thule settlements in north-eastern Greenland
Authors: Kalkreuth Wolfgang , Andreasen Claus , Petersen Henrik I. , Stemmerik Lars
Published: January 2021

Coal petrographic techniques have been used to trace the origin of coal used to produce artifacts by the Thule people in north-eastern Greenland. The coal artifacts were collected from the north-east coast settlements between 76°55'–80°18'N and date back to the 15th century A.D.
The petrographic data suggest that they have a common source, the Middle Jurassic coals outcropping south of 75°15' in north-eastern Greenland. It is thus evident that the Thule people used local material rather than bringing the coal from the known “mines” in Arctic Canada. It also implies that contemporaneous Thule people groups along the east coast of Greenland were in contact and traded.
Depositional environments of Lower Cretaceous (Ryazanian– Barremian) sediments from Wollaston Forland and Kuhn Ø, North-East Greenland
Authors: Pauly Sebastian , Mutterlose Jørg , Alsen Peter
Published: January 2021

Lower Cretaceous sediments from the Wollaston Forland–Kuhn Ø area in North-East Greenland have been analyzed for stable carbon isotopes, total organic carbon (TOC) content, and major and trace elements, aiming at a lithological characterization and reconstruction of the depositional environments.

The marine sediments of Ryazanian–Barremian age were deposited in North-East Greenland directly after a major Late Jurassic – earliest Cretaceous rifting event.

The Lower Cretaceous post-rift sediments are composed of fossiliferous calcareous mud- and marlstones assigned to the Albrechts Bugt (upper Ryazanian – Valanginian) and Rødryggen (Hauterivian) Members. The calcareous sediments are commonly sandwiched between black mudstones of Late Jurassic – earliest Cretaceous (Bernbjerg Formation) and mid Cretaceous (unnamed formation) age.

The carbon isotope curves present the first record for the Lower Cretaceous (upper Ryazanian – Barremian) of North-East Greenland. The Ryazanian – Hauterivian sediments are characterized by a mixture of terrigenous detrital matter (quartz, clay minerals, heavy minerals) similar to average shale, with varying CaCO3 concentrations. The Barremian black mudstones on the contrary have lower CaCO3 and higher clay mineral contents. The deposition of the Bernbjerg Formation took place under anoxic bottom water conditions.

The depositional environment of the Albrechts Bugt and Rødryggen Members is characterized by well-oxygenated sea-floor conditions, hemipelagic sedimentation of fine-grained terrigeneous detrital matter, and biogenic carbonate settling. After this relatively short interval of carbonate sedimentation under oxic conditions, bottom waters were affected by dysoxic conditions, responsible for the burial of organic matter in the Barremian.
Imitation or Polarity Correspondence? Behavioural and Neurophysiological Evidence for the Confounding Influence of Orthogonal Spatial Compatibility on Measures of Automatic Imitation
Authors: Czekóová Kristína , Shaw Daniel Joel , Lamoš Martin , Špiláková Beáta , Salazar Miguel , Brázdil Milan
Published: January 2021

During social interactions, humans tend to imitate one another involuntarily. To investigate the neurocognitive mechanisms driving this tendency, researchers often employ stimulus-response compatibility (SRC) tasks to assess the influence that action observation has on action execution. This is referred to as automatic imitation (AI). The stimuli used frequently in SRC procedures to elicit AI often confound action-related with other nonsocial influences on behaviour; however, in response to the rotated hand-action stimuli employed increasingly, AI partly reflects unspecific up-right/down-left biases in stimulus-response mapping. Despite an emerging awareness of this confounding orthogonal spatial-compatibility effect, psychological and neuroscientific research into social behaviour continues to employ these stimuli to investigate AI. To increase recognition of this methodological issue, the present study measured the systematic influence of orthogonal spatial effects on behavioural and neurophysiological measures of AI acquired with rotated hand-action stimuli in SRC tasks. In Experiment 1, behavioural data from a large sample revealed that complex orthogonal spatial effects exert an influence on AI over and above any topographical similarity between observed and executed actions. Experiment 2 reproduced this finding in a more systematic, within-subject design, and high-density electroencephalography revealed that electrocortical expressions of AI elicited also are modulated by orthogonal spatial compatibility. Finally, source localisations identified a collection of cortical areas sensitive to this spatial confound, including nodes of the multiple-demand and semantic-control networks. These results indicate that AI measured on SRC procedures with the rotated hand stimuli used commonly might reflect neurocognitive mechanisms associated with spatial associations rather than imitative tendencies.

Novel coronavirus SARS-CoV-2 infection (COVID-19) is a dangerous disease for older adults. Preventive measures in this population should involve three groups of measures: 1) prevention of infection; 2) prevention of functional decline and geriatric syndromes, including social support; 3) control of chronic comorbidity. Older adults are common to present with atypical COVID-19 symptoms, and mildness of symptoms (no fever, cough, shortness of breath) does not correspond to the severity of the prognosis. Delirium may be the first manifestation of COVID-19, that is why it is screening should be widely implied. Risk of malnutrition resulting in sarcopenia increases during the hospitalization, especially if mechanical ventilation required, and promotes frailty progression and decreases quality of life after the discharge from the hospital. Geriatric assessment is an important component of the decision making process in the management of older adults.

Aim: to assess the most important metabolic factors in centenarians and their impact on prognosis Materials and methods. It was a longitudinal study, including 64 centenarians (95 years and older), who live in Moscow. Complex geriatric assessment (FRAIL, IADL-C, MNA, GDS-15 and МOCA scores) and blood tests (HbA1c, cholesterol, LDL, HDL and TG) were performed. In 3 years we contacted patients’ relatives or social workers to find out about patients’ status. Results. Mean age of the patients was 98,3±1,9 years. We found out that 34,4% of the patients were frail. Cognitive impairments of different severity were presented in 84,4% of the patients. The median lipids values were as follows: cholesterol — 4,8 [4,2 ;5,8], TG — 0.97 [0,8; 1.2], HDL — 1.3 [4.2; 5,8), LDL — 3,1 [2,6; 3,7], HbA1c — 5,8 [5,6; 6,1]. In 59% of the patients HbA1c was below 6%; 33% had concentrations between 6% and 6,4%, and only in 8% we found HbA1c higher than 6,5%. No correlation was also found between HbA1c values and lipids profile. Comparing survivors and non-survivors groups we did not find any significant differences in total cholesterol, LDL, HDL and HbA1c (p<0,005). While comparing functional status with metabolic profile we discovered positive correlation (r= 0.834) between total cholesterol and index of instrumental activity, and between LDL and IADL as well as MNA score (r=0.732 and 0.634 respectively). Conclusions. In centenarians usual prognostic factors such as HbA1c and lipids do not have any impact on prognosis but they influence functional status and QoL. Further investigations of metabolic status in super old persons are needed to personalize their lifestyle and treatment goals.

Aim: to estimate the associations between employment status, functional and cognitive status, physical health, and geriatric syndromes in women aged 55–64. Materials and methods. A cross-sectional study included 250 women aged 55 to 64 years. Sociodemographic factors, functional and cognitive status, health status, risk factors for chronic noncommunicable diseases (NCD), and presence of NCD were analyzed. The prevalence of changes indicative of geriatric syndromes was estimated. Results. The study included 250 women aged 55–64 years (mean age 59.3 ± 2.9 years). Risk factors (RF) for NCD were identified in all subjects. Abdominal obesity and lipid metabolism disorders (increased blood cholesterol levels and LDL cholesterol levels) were the most common RFs for NCD. The incidence of dyslipidemia as RF NCD was 94%. CVD, diseases of the musculoskeletal system, gastrointestinal tract (GIT), varicose veins of the lower extremities, and endocrine pathology prevailed in NCD. In women aged 55–64 years, aging increases the likelihood that a woman will not work by 2.5 times, using ≥two assistive devices — 2 times, the presence of urinary incontinence/ leakage — 2.3 times, probable depression — 2.7 times. Conclusion: geriatric syndromes are primarily associated with a decrease in functional activity in women aged 55-64 years; this association is associated with socio-demographic, economic factors, and health status (the presence of FRs for NCD and NCD themselves).

Relevance: the steady increase in the number of patients with respiratory diseases caused by the new SARS-CoV-2 coronavirus, among which pneumonia accounts for up to 22%, creates global problems associated with the treatment of patients and their subsequent rehabilitation. The insufficiently understood long-term consequences of COVID-19 in combination with concomitant chronic diseases and geriatric syndromes require special tactics of rehabilitation, observation and treatment of older people, including remotely. Aim: to present up-to-date data on the feasibility, efficacy and safety of approaches to the rehabilitation of older patients after pneumonia caused by SARS-CoV-2 Material and Methods: the analysis of modern domestic and foreign literature on the rehabilitation of older patients after pneumonia caused by SARS-CoV-2 was carried out, the experience of organizing rehabilitation in real clinical practice was studied, taking into account the continuity of the inpatient and abulatory stages of rehabilitation. Results: the most promising for respiratory rehabilitation are the first two months after the acute period of coronavirus infection. The priority goals of providing medical care to older people within the framework of rehabilitation are to prevent or slow down functional impairments, helplessness, disability, maintain mobility and maintain mental health. Conclusion: rehabilitation of older patients at the outpatient stage after suffering from COVID-19 should begin, if possible, as early as possible. A thorough assessment of the clinical and functional status and a comprehensive treatment plan, which focuses on functional activity and return to participation in the life of society, depending on the individual characteristics of the person and the volume of medical services, will help each patient to maximize their condition and quality of life.

This case shows a patient with a fall syndrome, which resulted in a severe rib fracture. The patient was thoroughly examined to identify the probable causes and risk factors for falls. The results of physical examination, comprehensive geriatric assessment and additional research methods revealed such geriatric syndromes as frailty, falls syndrome, vitamin D deficiency, peripheral polyneuropathy, and carotid artery stenosis. Thus, as a result of the examination, 7 risk factors for falls were identified in the patient, which turned out to be fully or partially modifiable.

Preventing decreased physical and functional activity in older adults during hospitalization is a geriatric care protocol for nurses. The frailty and the formation of long-term care dependence is a stronger predictor of mortality and is more important for assessing the prognosis for the quality of life and surviving an older patient than even the presence of specific diseases and maintaining a baseline level of daily activity for the patient. Activities aimed at maintaining physical, cognitive, and social functioning (increasing physical activity, socialization, etc.) will help ensure an increase in the level of physical functioning and older patients' safety.
Current problems and prospects of transport logistics development in the convenience of COVID-19 coronavirus pandemic

Published: January 2021

The paper analyzes the main trends in the transport logistics market before the emergence of the coronavirus pandemic and in the process of its occurrence. Emphasis is placed on the dynamics of passenger and freight turnover. The number of transported passengers and volumes of transported goods by types of transport are reflected. The main risks of transport logistics in the conditions of COVID-19 are described taking into account features of the internal market. The paper examines the current problems of transport logistics in the context of the COVID-19 coronavirus pandemic and potential ways to solve them.
Many scientists have conducted research to improve the efficiency of transport logistics, in particular, freight, which are relevant areas of development, because the competitiveness of freight forwarding companies in a pandemic COVID-19 directly depends on the proper use of methods of logistics. Today, transport logistics is important for the planning process, forecasting not only the amount of costs directly for delivery, but also in the formation of plans for transport costs in general in order to fully fulfill the order of consumers of transport services. That is why the issue of transport logistics development in the context of the coronavirus pandemic COVID-19 is extremely relevant.
The COVID-19 coronavirus pandemic is affecting the global economy and every business in particular. Suspension of enterprises in different countries of the world, closure of passenger flights, reduction of production volumes – all this was reflected in the logistics of freight transportation. Today, logistics, like other areas of business, is experiencing turbulence as a result of the spread of Covid-19 in the world and in Ukraine. Now the delivery of goods and personal orders is carried out according to the usual schedules, but changes in the work of logistics and transport companies are also taking place.
Statistical Precision – Recall curves for object detection quality assessment
Authors:   Financial University under the Government of the Russian Federation, Kuznetsova Anna A.
Published: January 2021

Average precision (AP) as the area under the Precision – Recall curve is the de facto standard for comparing the quality of algorithms for classification, information retrieval, object detection, etc. However, traditional Precision – Recall curves usually have a zigzag shape, which makes it difficult to calculate the average precision and to compare algorithms. This paper proposes a statistical approach to the construction of Precision – Recall curves when assessing the quality of algorithms for object detection in images. This approach is based on calculating Statistical Precision and Statistical Recall. Instead of the traditional confidence level, a statistical confidence level is calculated for each image as a percentage of objects detected. For each threshold value of the statistical confidence level, the total number of correctly detected objects (Integral TP) and the total number of background objects mistakenly assigned by the algorithm to one of the classes (Integral FP) are calculated for each image. Next, the values of Precision and Recall are calculated. Precision – Recall statistical curves, unlike traditional curves, are guaranteed to be monotonically non-increasing. At the same time, the Statistical Average Precision of object detection algorithms on small test datasets turns out to be less than the traditional Average Precision. On relatively large test image datasets, these differences are smoothed out. The comparison of the use of conventional and statistical Precision – Recall curves is given on a specific example.
Community-centered P/CVE Research in Southeast Asia: Opportunities and Challenges
Authors: Vergani Matteo
Published: January 2021

The definition and understanding of community-centered preventing and countering violent extremism (P/CVE) research lacks analytical clarity. This chapter examines this concept with a focus on the Southeast Asian context, reflecting on opportunities, challenges, and pitfalls, to lay the foundation for future theorization and comparative P/CVE research in local contexts. Collaboration with independent and genuine community actors is advantageous for all stakeholders, since deficient trust, tamed and crystallized relationships, and a lack of resources and capacities can result in biased research findings. The chapter advocates for the establishment of research and evaluation frameworks in National Action Plans, with the aim to set out common definitions, measurement tools, and methodologies in consultation with all stakeholders, including community actors. This is a necessary step in producing systematic, cumulative, and comparative research and evaluation findings that hold true across local contexts. Finally, the chapter discusses the ethical implications of conducting community-centered P/CVE research with minority communities––such as the creation of suspicious, ostracized, and alienated communities––as well as with majority communities. It also speaks to the potential for research findings and topics of focus interfering in or being instrumentalized to impact a country’s democratic process. Although the Southeast Asian context is used to discuss the opportunities and challenges of the different approaches to community-centered P/CVE research, key findings are likely relevant to other contexts.

Abstract- Having a sophisticated application, even though often experience problems in deciding BUY - SELL in trading forex trading. This is due to the often time series predictions, in the high variable experiencing high values ​​as well as low variables, for that it is needed a recommendation system to overcome this problem.

The application of classification algorithms to the recommendation system in support of BUY-SELL decisions is one appropriate alternative to overcome this. K-Nearest Neighbor (K-NN) algorithm was chosen because the K-NN method is an algorithm that can be used in building a recommendation system that can classify data based on the closest distance. This system is designed to assist traders in making BUY-SELL decisions, based on predictive data.

The results of the recommendation system from the ten trials predicted by Arima are recommended. When compared to the price in the field the target profit is 7% per week from ten experiments if the average profit has exceeded the target

This article discusses the Performance of Free Software and Freeware in Telecommunication System. Software or software is a special term for data that is digitally formatted and stored, including computer programs, their documentation, and various information that can be read and written by a computer. In other words, part of a computer system that is intangible. This term emphasizes the difference from computer hardware. Making the software itself requires a "programming language" written by the programmer which is then compiled with the compiler application so that it becomes code that can be recognized by the hardware machine.
