Published: December 2021

Widespread use of web-based systems in business, marketing, e-learning, etc. makes it necessary to take into account and analyze the information needs of the user in order to optimize interaction with him. One of the main problems of creating adaptive web-based systems is the task of classifying information resources (pages) of the portal describing the offered product or service, for the subsequent formation of the user profile and personalized recommendations of services. Data mining and machine learning methods can be used to solve this problem. The article presents a new approach to creating adaptive web-based information systems using the reinforcement learning algorithms to classify information resources and to form personalized recommendations to users based on their preferences. An adaptive approach is proposed and justified, based on the use of Reinforcement Learning procedures, which allows you to automatically find the most effective strategies for the correct classification of the site's resources and the formation of user groups with the same type of requests and preferences. The proposed scheme allows you to create procedures for evaluating and ranking information resources of the system based on the analysis of user behavior on the site online. The reinforcement learning algorithms used make it possible to evaluate the relevance of each page of the site to the requests and preferences of the users from different categories in order to optimize the structure and content of the site, as well as to build an effective system of recommendations in accordance with the user's interests to be able to choose the most suitable products or services.

A method is proposed for preliminary assessment of the pragmatic value of information in the problem of classifying the state of an object based on deep recurrent networks of long short-term memory. The purpose of the study is to develop a method for predicting the state of a controlled object while minimizing the number of used prognostic parameters through a preliminary assessment of the pragmatic value of information. This is an especially urgent task under conditions of processing big data, characterized not only by significant volumes of incoming information, but also by information rate and multiformatness. The generation of big data is now happening in almost all areas of activity due to the widespread introduction of the Internet of Things in them. The method is implemented by a two-level scheme for processing input information. At the first level, a Random Forest machine learning algorithm is used, which has significantly fewer adjustable parameters than a recurrent neural network used at the second level for the final and more accurate classification of the state of the controlled object or process. The choice of Random Forest is due to its ability to assess the importance of variables in regression and classification problems. This is used in determining the pragmatic value of the input information at the first level of the data processing scheme. For this purpose, a parameter is selected that reflects the specified value in some sense, and based on the ranking of the input variables by the level of importance, they are selected to form training datasets for the recurrent network. The algorithm of the proposed data processing method with a preliminary assessment of the pragmatic value of information is implemented in a program in the MatLAB language, and it has shown its efficiency in an experiment on model data.

Indonesia confirmed the spread of Covid-19 since the beginning of March 2020. Until now, this virus has had an impact on almost all areas of life, not only health but also the economy, especially education. In the field of education, the government implements regulations regarding online learning systems or Distance Learning (PJJ) by means of Study From Home (Learning From Home). Online learning is a new thing for educational institutions. Many obstacles that occur include the teacher still having difficulty in determining the use of appropriate media for international learning. Another obstacle is the lack of parental assistance. Therefore, the authors conducted online learning assistance for SD / MI students using interactive learning media. Researchers used mentoring strategies and the methods used were online and offline methods. The result of the mentoring process using interactive learning media is the increased interest, motivation and achievement of students and this is an ineffective solution to online learning problems. There are many factors in the implementation of online learning assistance for SD / MI students in Guci village, both supporters and obstacles. Among the supporting factors are the talents, high interest and motivation of students, family support, school, community. The inhibiting factors are the lack of facilities or infrastructure used for learning both online and face-to-face, the lack of discipline of students during face-to-face mentoring, lack of discipline in using masks, and so on.

Since the genesis of 21st century, sustainable development has been one of the key growth concerns for many developing countries. Designing services have taken a new shape with implications of sustainability being the heart of many significant developments in the financial industry in India. Considering the requirements of the regulatory framework and policy makers, banks are encouraged towards adopting a more pro-active and sensible approach towards designing their product services. These are in view of better serving their customers and cater for future developments. The purpose of their paper is to enquiry into the basis of sustainable service design aspect of banks in the Indian context despite its undisputed value for financial organisations attempting to comply with sustainability framework and policy makers to develop a sustainable development culture. The research design is exploratory in nature, which comprises extensive literature review coupled with indepth qualitative data collection from selected industry practitioners. The literature reviews clearly indicates the significance, value and power of sustainable service design. Based on results of the literature review and collected data, managerial extrapolations have been devised. To our knowledge, there has been no evident effort to investigate this research in the Indian Service banking industry regardless of the richness and value it holds.
Changes in Serum Dickkopf-1, RANK Ligand, Osteoprotegerin, and Bone Mineral Density after Allogeneic Hematopoietic Stem Cell Transplantation Treatment
Authors: Jang Eunhee , Ha Jeonghoon , Baek Ki-Hyun , Kang Moo Il
Published: December 2021

Background: Dickkopf-1 (DKK1) regulates bone formation by inhibiting canonical Wnt/β-catenin pathway signaling, and indirectly enhances osteoclastic activity by altering the expression ratio of receptor activator of nuclear factor-κB ligand (RANKL) relative to osteoprotegerin (OPG). However, it is difficult to explain continued bone loss after allogeneic stem cell transplantation (allo-SCT) in terms of changes in only RANKL and OPG. Few studies have evaluated changes in DKK1 after allo-SCT.Methods: We prospectively enrolled 36 patients with hematologic malignancies who were scheduled for allo-SCT treatment. Serum DKK1, OPG, and RANKL levels were measured before (baseline), and at 1, 4, 12, 24, and 48 weeks after allo-SCT treatment. Bone mineral density (BMD) was assessed using dual-energy X-ray absorptiometry before (baseline) and 24 and 48 weeks after allo-SCT treatment.Results: After allo-SCT treatment, the DKK1 level decreased rapidly, returned to baseline during the first 4 weeks, and remained elevated for 48 weeks (P<0.0001 for changes observed over time). The serum RANKL/OPG ratio peaked at 4 weeks and then declined (P<0.001 for changes observed over time). BMD decreased relative to the baseline at all timepoints during the study period, and the lumbar spine in female patients had the largest decline (–11.3%±1.6% relative to the baseline at 48 weeks, P<0.05).Conclusion: Serum DKK1 levels rapidly decreased at 1 week and then continued to increase for 48 weeks; bone mass decreased for 48 weeks following engraftment in patients treated with allo-SCT, suggesting that DKK1-mediated inhibition of osteoblast differentiation plays a role in bone loss in patients undergoing allo-SCT.

Lensa kontak merupakan alat bantu penglihatan yang memberi kenyamanan beraktifitas dan lebih baik secara estetik, namun penggunaan dan perawatan yang kurang atau tidak tepat dapat menimbulkan komplikasi ringan sampai berat. Kebersihan dan kepatuhan yang kurang baik dalam penggunaan dan perawatan lensa kontak dapat menjadi faktor resiko terjadinya peradangan pada mata, hal ini disebabkan karena dalam beberapa menit pemakaian lensa kontak menjadi cepat dilapisi dengan berbagai komponen film air mata berupa protein, lipid, dan lendir. Komponen ini disebut dengan deposit. Tujuan dari penelitian ini adalah untuk mengidentifikasi kandungan deposit yang ditemukan pada lensa kontak pasca pemakaian. Penelitian ini merupakan penelitian deskriptif dengan pendekatan metode potong lintang (cross sectional), dimana sampel sebanyak 5 orang diminta menggunakan lensa kontak dalam waktu 8 jam setiap hari selama 2 minggu berturut-turut. Hasil menunjukkan adanya deposit pada lensa kontak berupa protein, lipid, kalsium, dan kontaminasi make up pada setiap sampel. Hal ini kemungkinan disebabkan karena adanya paparan debu, lingkungan serta hygine pengguna lensa kontak yang kurang baik, termasuk dalam hal cara perawatannya. Dengan demikian diperlukan metode edukasi dan prosedur perawatan lensa kontak yang lebih sederhana untuk meningkatkan kepatuhan pengguna lensa kontak dalam melakukan perawatan.

The expectations facing the civil service executives and their everyday challenges are outstandingly complex. During the career of an executive a number of hardships occur, which cannot be overcome with standard responses. The individual problems require individual solutions. The innovative training forms adapted to the expectations of the 21st century are able to appropriately support the strengthening of the successes of the executives. The following are indispensable for the leaders: high level self-knowledge, leadership consciousness and the ability of self-reflexion. These capabilities may be efficiently developed with the aid of coaching based training. This ensures the integration of the new knowledge and behaviour patterns into everyday work, self-reflection, and the increase of leadership consciousness. Skill level acquiring and in-depth learning of competences are far more successful with coaching than with any other learning form. According to the researches, coaching is a personalised, highly efficient competence development system that takes into consideration the loads and burdens of the leaders, and which is flexible as regards time and space. The coaching method is regularly used by the decisive majority of the international civil service training practice. Unlike the case of domestic civil service. The further training system operates both in the area of public administration and in the area of law enforcement. It pays an increasing attention beyond vocational preparedness also to the development of competence. The purpose of civil service further training is to encourage the voluntary learning of the staff, to awaken their motivation and instead of conveying static knowledge to form the attitude, value orientation and self- development of soft skills. Instead of the traditional lecture -focused training forms the using of practical training and the method of e-learning became widespread in the recent years. In the case of both professional areas it is possible to complete short one-three day and e-learning courses of the training palette and methodology which are under continuous development. At the same time, the introduction of several training methods of advanced approach (as e.g., coaching) has been started to be used only in a scattered manner. It would be possible to increase the performance of the executives working in the civil service organizations significantly by integration and system-level development of these methods, and through this it would be possible to increase the performance of the organisational units themselves considerably. Our study briefly introduces the executive training system of law enforcement and civil service, its results, and it examines the international and domestic practice of the appearance of coaching based executive training, as well as the huge amount of inherent, unexploited potentials.

Lost Horizon: Quantifying the Effect of Local Topography on Global 21 cm Cosmology Data Analysis

Published: December 2021

We present an investigation of the horizon and its effect on global 21 cm observations and analysis. We find that the horizon cannot be ignored when modeling low-frequency observations. Even if the sky and antenna beam are known exactly, forward models cannot fully describe the beam-weighted foreground component without accurate knowledge of the horizon. When fitting data to extract the 21 cm signal, a single time-averaged spectrum or independent multi-spectrum fits may be able to compensate for the bias imposed by the horizon. However, these types of fits lack constraining power on the 21 cm signal, leading to large uncertainties on the signal extraction, in some cases larger in magnitude than the 21 cm signal itself. A significant decrease in uncertainty can be achieved by performing multi-spectrum fits in which the spectra are modeled simultaneously with common parameters. The cost of this greatly increased constraining power, however, is that the time dependence of the horizon’s effect, which is more complex than its spectral dependence, must be precisely modeled to achieve a good fit. To aid in modeling the horizon, we present an algorithm and Python package for calculating the horizon profile from a given observation site using elevation data. We also address several practical concerns such as pixelization error, uncertainty in the horizon profile, and foreground obstructions such as surrounding buildings and vegetation. We demonstrate that our training-set-based analysis pipeline can account for all of these factors to model the horizon well enough to precisely extract the 21 cm signal from simulated observations.

We present 97 new high-quality strong lensing candidates found in the final ∼350 deg2 that complete the full ∼1350 deg2 area of the Kilo-Degree Survey (KiDS). Together with our previous findings, the final list of high-quality candidates from KiDS sums up to 268 systems. The new sample is assembled using a new convolutional neural network (CNN) classifier applied to r-band (best-seeing) and g, r, and i color-composited images separately. This optimizes the complementarity of the morphology and color information on the identification of strong lensing candidates. We apply the new classifiers to a sample of luminous red galaxies (LRGs) and a sample of bright galaxies (BGs) and select candidates that received a high probability to be a lens from the CNN (P
CNN). In particular, setting P
CNN > 0.8 for the LRGs, the one-band CNN predicts 1213 candidates, while the three-band classifier yields 1299 candidates, with only ∼30% overlap. For the BGs, in order to minimize the false positives, we adopt a more conservative threshold, P
CNN > 0.9, for both CNN classifiers. This results in 3740 newly selected objects. The candidates from the two samples are visually inspected by seven coauthors to finally select 97 “high-quality” lens candidates which received mean scores larger than 6 (on a scale from 0 to 10). We finally discuss the effect of the seeing on the accuracy of CNN classification and possible avenues to increase the efficiency of multiband classifiers, in preparation of next-generation surveys from ground and space.

Published: December 2021

Invasive predators can strongly affect native populations. If alien predator pressure is strong enough, it can induce anti-predator responses, including phenotypic plasticity of exposed individuals and local adaptations of impacted populations. Furthermore, maternal investment is an additional pathway that could provide resources and improve performance in the presence of alien predators. We investigated the potential responses to an alien predator crayfish (Procambarus clarkii) in a threatened frog (Rana latastei) by combining field observations with laboratory measurements of embryo development rate, to assess the importance of parental investment, origin and exposure to the crayfish cues. We detected a strong variation in parental investment amongst frog populations, but this variation was not related to the invasion status of the site of origin, suggesting that mothers did not modulate parental investment in relation to the presence of alien predators. However, cues of the invasive crayfish elicited plastic responses in clutches and tadpoles development: embryos developed faster when exposed to the predator. Furthermore, embryos from invaded sites reached Gosner’s development stage 25 faster than those from non-invaded sites. This ontogenetic shift can be interpreted as a local adaptation to the alien predator and suggests that frogs are able to recognise the predatory risk. If these plastic responses and local adaptation are effective escape strategies against the invasive predator, they may improve the persistence of native frog populations.

Wild type genotypes (CYP2D6) and their allelic variants have been described in a sample of a Peruvian mestizo population. The global allele frequency was 0.015 for CYP2D6*3 and 0.051 for CYP2D6*4. The percentages of genotypes described were 97% CYP2D6*1/*1 and 3.0% CYP2D6*1/*3; 90.60% for CYP2D6*1/*1, 8.55% CYP2D6*1/*4 and 0.85% CYP2D6*4/*4. The allelic frequencies of CYP2D6*3 in the Lima subpopulations were 0.022 and 0.010 for Junin; CYP2D6*4 of 0.048, 0.060, and 0.050 for residents of Lima, Junín, and Tacna, respectively. The Hardy-Weinberg equilibrium test for the studied population showed that both frequencies are in equilibrium, p <.05. The metabolizer phenotype was inferred according to the genotypes: 11.54% were classified as intermediate metabolizers (*1/*3 or *1/*4) and 0.85% as poor metabolizers (*4/*4). It is concluded that the frequencies of the CYP2D6*3 and CYP2D6*4 alleles are low for the Peruvian mestizo population compared to the Latin American and tricontinental population, due to their natural population evolution, which is manifested by their decreased metabolic activity, the same that is relevant in clinical practice.
Designation of the neotype of Triatoma dimidiata (Latreille, 1811) (Hemiptera, Reduviidae, Triatominae), with full integrated redescription including mitogenome and nuclear ITS-2 sequences
Authors: Justi Silvia Andrade , Dale Carolina
Published: December 2021

The taxonomic status of Triatoma dimidiata (Latreille, 1811) is, by far, the most discussed within Triatominae. Molecular studies have recovered at least three independently evolving lineages in T. dimidiata across its range. The original description of T. dimidiata (as Reduvius dimidiatus) included few taxonomic characters, and no types were assigned. To define and describe the cryptic diversity within T. dimidiata sensu lato (s.l.), a neotype must be designated. For this purpose, all 199 specimens identified as T. dimidiata from the collections of the Smithsonian Institution – National Museum of Natural History and the American Museum of Natural History, ranging from Peru to Mexico, were studied. Only one specimen (from Tumbes, Peru) matched the combination of characters as listed in the original description, and it is herein formally designated as the neotype for T. dimidiata. The neotype is morphologically described and DNA sequences of its whole mitochondrial genome and the nuclear second internal transcribed spacer region (ITS2), commonly used in triatomine molecular systematics studies, are presented and compared to other publicly available sequences of T. dimidiata s.l. in GenBank. Our results suggest that T. dimidiata sensu stricto (s.s.) is somewhat rare and, therefore, unlikely to serve as a major vector of Chagas disease.

Authors: Zauszniewski Jaclene , Bekhet Abir , Haberlein Sara
Published: December 2021

Current psychiatric nursing practice remains grounded in tradition, unsystematic trial and error, and authority. Although some of the wisdom that has been passed down over time is questionable, it continues to influence nursing practice today. This state-of-the-evidence review examined features of intervention studies published between January 2006 and December 2010 in five psychiatric nursing journals; it compared findings with those from a previous study of comparable literature published between 2000 and 2005. The analysis included studies that evaluated strategies, procedures, or practices that promote mental health or prevent mental illness. Of the 553 data-based articles, 71% tested interventions; 54% were conducted in the United States. Intervention studies reflected psychological (38%) social (17%), and biological (1%) dimensions of the biopsychosocial model. Some studies involved two dimensions and 17% included all three dimensions. Studies involved nurses, students, or staff (15%), mentally ill (50%), or mentally healthy persons (35%) ranging in age from childhood through older adulthood. The 10 year review showed continuing progress toward increased dissemination compared to earlier years; less focus on nurses, students, and staff; an increase in international studies; and greater emphasis on holistic interventions. In this article, the authors note a need for more randomized, controlled trials and studies to compare effectiveness across interventions.
Advancing Nursing Practice Through Social Media: A Global Perspective
Authors: Barry Jean , Hardiker Nicholas
Published: December 2021

Social media has been used globally as a key vehicle for communication. As members of an innovative profession, many nurses have embraced social media and are actively utilizing its potential to enhance practice and improve health. The ubiquity of the Internet provides social media with the potential to improve both access to health information and services and equity in health care. Thus there are a number of successful nurse-led initiatives. However, the open and democratising nature of social media creates a number of potential risks, both individual and organisational. This article considers the use of social media within nursing from a global perspective, including discussion of policy and guidance documents. The impact of social media on both healthcare consumers and nurses is reviewed, followed by discussion of selected risks associated with social media. To help nurses make the most of social media tools and avoid potential pitfalls, the article conclusion suggests implications appropriate for global level practice based on available published guidance.
Elder Mistreatment and the Elder Justice Act
Authors: Falk Nancy , Baigis Judith , Kopac Catharine
Published: December 2021

Elder mistreatment is unrecognized, hidden, and underreported. Studies show that health professionals, nurses among them, are largely unaware of the various forms of elder mistreatment that take place and of the proper course of action to pursue when mistreatment is suspected. In this article, we describe elder mistreatment policies, examining them in the light of the United States’ national elder abuse policies with a focus on important provisions of the Elder Justice Act. Next, we review the various types of abuse, the identification of abuse, and the nurses’ role in addressing elder mistreatment. We present an example of a case of physical abuse and conclude by discussing nurses' advocacy role and issuing a call to action, challenging nurses to ‘act now’ to protect the well being of elders.

The problem of online game addiction among teenagers is becoming more and more serious in many parts of the world. Many of them are addicted to online games due to the lack of family education, which is an important factor that can not be ignored. To explore the optimal strategy for controlling the spread of game addiction, a new dynamic model of teenagers' online game addiction with considering family education is developed. Firstly, we perform a qualitative dynamic analysis of the model. We study the nonnegativity and boundedness of solutions, the basic reproduction number $ R_{0} $, and the existence and stability of equilibria. We then consider a model with control measures of family education, isolation and treatment, and obtain the expression of optimal control. In the numerical simulation, we study the global sensitivity analysis by the combination of Latin Hypercube Sampling (LHS) and partial rank correlation coefficient (PRCC) techniques, and show the relationship between $ R_{0} $ and each parameter. Then the forward backward sweep method with fourth order Runge-Kutta is used to simulate the control strategy in each scenario. Finally, the optimal control strategy is obtained by comparing incremental cost-effectiveness ratio (ICER) and infection averted ratio (IAR) under all strategies. The results show that with sufficient financial resources, adding the family education measures can help more teenagers avoid being addicted to games and control the spread of game addiction more effectively.

Most of the malignant melanomas are already in the middle and advanced stages when they are diagnosed, which is often accompanied by the metastasis and spread of other organs. Besides, the prognosis of patients is bleak. The characteristics of the local immune microenvironment in metastatic melanoma have important implications for both tumor progression and tumor treatment. In this study, data on patients with metastatic melanoma from the TCGA and GEO datasets were selected for immune, stromal, and estimate scores, and overlapping differentially expressed genes were screened. A nine-IRGs prognostic model (ALOX5AP, ARHGAP15, CCL8, FCER1G, GBP4, HCK, MMP9, RARRES2 and TRIM22) was established by univariate COX regression, LASSO and multivariate COX regression. Receiver operating characteristic curves were used to test the predictive accuracy of the model. Immune infiltration was analyzed by using CIBERSORT and Xcell in high-risk and low-risk groups. The immune infiltration of the high-risk group was significantly lower than that of the low-risk group. Immune checkpoint analysis revealed that the expression of PDCD1, CTLA4, TIGIT, CD274, HAVR2 and LAG3 demonstrated the visible difference in groups with different levels of risk scores. WGCNA analysis found that the yellow-green module contained seven genes from the nine-IRG prognostic model, and the yellow-green module had the highest correlation with risk scores. The results of GO and KEGG suggested that the genes in the yellow-green module were mainly enriched in immune-related biological processes. Finally, the expression characteristics of ALOX5AP, ARHGAP15, CCL8, FCER1G, GBP4, HCK, MMP9, RARRES2 and TRIM22 were analyzed between metastatic melanoma and normal samples. Overall, a prognostic model for metastatic melanoma based on the tumor immune microenvironment characteristics was established, which left plenty of space for further studies. It could function well in helping people to understand characteristics of the immune microenvironment in metastatic melanoma.

Cloud computing is an attractive model that provides users with a variety of services. Thus, the number of cloud services on the market is growing rapidly. Therefore, choosing the proper cloud service is an important challenge. Another major challenge is the availability of diverse cloud services with similar performance, which makes it difficult for users to choose the cloud service that suits their needs. Therefore, the existing service selection approaches is not able to solve the problem, and cloud service recommendation has become an essential and important need. In this paper, we present a new way for context-aware cloud service recommendation. Our proposed method seeks to solve the weakness in user clustering, which itself is due to reasons such as 1) lack of full use of contextual information such as cloud service placement, and 2) inaccurate method of determining the similarity of two vectors. The evaluation conducted by the WSDream dataset indicates a reduction in the cloud service recommendation process error rate. The volume of data used in the evaluation of this paper is 5 times that of the basic method. Also, according to the T-test, the service recommendation performance in the proposed method is significant.
