Actualizing Robert Jervis
Authors: Surguladze Vakhtang Sh.
Published: June 2023

The first Russian edition of Robert Jervis's classical work on the problems of perception and misperception in world politics draws attention to the need to strengthen the sovereignty and national security of the Russian Federation in the socio-humanitarian, socio-cultural and scientific spheres. Supplemented by a review of scientific achievements in the field of cognitive psychology and neuro-politics, the study by a well-known American political scientist is a useful source of information about the latest trends in the study of socio-political behavior and makes us rethink the state and directions of development of socio-humanitarian disciplines in Russia. The article concludes that against the background of the latest discoveries in the field of neuroscience, there is an alarming tendency of hypertrophied interest in the study of big data and pseudo-mathematization of socio-humanitarian disciplines, often to the detriment of traditional country studies and the study of historically determined causal interactions of socio-political processes. At the same time, it is noted that modern scientific methods confirm the conclusions of scientists made in the period before the "neuroscientific turn" of recent decades.

Published: June 2023

The paper is devoted to reconstruction of Joseph Biden’s Indo-Pacific policy planning based on official documents. The region is understood as an objectively forming space based on factors independent of human interpretation. It is revealed that the US government doesn’t consider this space as common and aims to divide it into subregions according to its political interests. The US government introduces a four-element structure of the region, which has a purpose to contain both opponents (China, Russia, DPRK) and allies and partners. Also, it strives to adjust the regional architecture as a network of partnerships oriented towards the USA.

Published: June 2023

Sungai Bodri melewati tiga kabupaten yaitu Kabupaten Temanggung dan Kabupaten Semarang di bagian hulu serta Kabupaten Kendal di bagian tengah hingga hilir. Sungai Bodri berhulu di Gunung Sindoro, Gunung Prahu dan Gunung Ungaran serta bermuara di Pantai Utara Jawa. Luas Daerah Aliran Sungai (DAS) Bodri sampai muara adalah 1.610,8 km2 terbagi atas 5 sub DAS, yaitu Sub-DAS Wringin, Sub-DAS Lutut, Sub-DAS Logung, Sub-DAS Putih dan Sub-DAS Bodri Hilir. Alih fungsi lahan di hulu Sungai Bodri dan aktivitas penambangan material batu, kerikil dan pasir tanpa ijin mengakibatkan keseimbangan transport sedimen menjadi terganggu sehingga di beberapa tempat di ruas Sungai Bodri mengalami degradasi dasar sungai dan kelongsoran tebing/tanggul sungai. Salah satu lokasi longsoran yang perlu perhatian yang lebih mendetail adalah longsoran tebing kanan sungai di Desa Lanji Kecamatan Patebon Kabupaten Kendal. Untuk mengatasi permasalahan ini, telah dilakukan penanganan yang sifatnya darurat maupun permanen. Dalam pelaksanaan konstruksinya dijumpai banyak permasalahan, seperti kesulitan dalam pelaksanaan pekerjaan timbunan tanggul di bantaran, sampai putusnya kontruksi pile cap turap dan angkur yang telah terpasang hingga mengakibatkan separuh badan tanggul longsor. Untuk mengatasi permasalahan tersebut, maka perlu dilakukan kajian yang lebih konprehensip meliputi aspek hidrologi, hidrolika dan geoteknik untuk memastikan penyebab terjadinya longsoran serta dapat digunakan sebagai dasar dalam penentuan jenis penanganan yang akan dilakukan selanjutnya. Dari hasil analisis ini, disarankan beberapa hal sebagai langkah penanganan permanen, yaitu perlu dilakukan pengupasan tanah yang mengalami longsor dan dilakukan penimbunan ulang dengan material tanah yang baru, perlu dilakukan perbaikan tanah pondasi karena tanah pondasi termasuk jenis tanah lunak, untuk menghindari terjadinya longsoran di lereng sisi dalam dan meningkatkan stabilitas maka di kaki tanggul diperkuat konstruksi turap, untuk mengurangi efek gerusan dan laju aliran serta menangkap sedimen maka di depan turap perlu ditambah dengan kontruksi krib/bronjong.

Factors Associated with Older Adults’ Physical Restraints by Licensed Caregivers Working at Day Care Centers
Authors:   Korea Gerontological Society, Hong Song Iee , Park Seo Young
Published: June 2023

Since the National Long-Term Care Insurance of 2008, licensed caregivers for older adults have dramatically increased in Korea. In contrast to such trends, their care capacity has been socially concerned about violation against human rights such as elder abuse including physical restraints. The distinction between physical restraints and physical abuse is ambiguous at care settings which has brought in hot debate on the violation of human rights. Therefore, we investigated the extent to which caregivers’awareness of physical restraints and reasons of elder abuse and their witness of physical restraints are associated with their physical restraints on older adults. We used the secondary data collected from 3,859 licensed caregivers working at about 3,000 day care centers across the nation in 2017. First, we found that 10.7% of caregivers performed restrictive interventions. Second, the awareness of physical restraints, witness of others’physical restraints, and their own physical restraints are related to each other. Lastly, logistic regressions confirmed that caregivers’poor awareness of physical restraints, more witness of physical restraints by other caregivers, and higher perception of victim’s personality problems mainly causing elder abuse were more likely to increase their use of physical restraints. These findings suggest that care environment insensitive to human rights might lead to elder abuse by over-utilizing physical restraints. Also, it is fundamental to develop professional care culture of licensed caregivers towards person-centered care.

Authors:   Korea Gerontological Society, Kang Sun Kyung , Lee Choon Hee
Published: June 2023

This study aims to verify the mediating effect of depression in affecting life satisfaction of seniors with Internet addiction. To this end, 286 people aged above 65 old were surveyed online, and multiple regression analysis was conducted using Hayes (2018)'s PROCESS macro. The verification of the indirect effect was confirmed by performing the bootstrap method. As a result of the analysis, it was found that depression was completely mediated in the relationship between Internet addiction and life satisfaction in the elderly. In summary, first, Internet addiction was found to have a positive correlation with depression. Second, Internet addiction was found to have a negatively correlated with life satisfaction. Third, when Internet addiction and depression, which are independent and mediating variables, were put together, the influence of Internet addiction on life satisfaction did not appear. Therefore, it can be seen that Internet addiction in seniors affects depression as a complete medium rather than directly affecting life satisfaction. According to the results of this study, it was suggested that to improve the life satisfaction of the elderly, the Internet use should be maintained to a healthy degree, and to prevent and treat depression, welfare services for the elderly and daily resources should be expanded. In addition, different appropriate alternatives are needed by identifying the characteristics of each age group within seniors. It was also proposed to systematize group counseling treatment for the elderly addicted to the Internet and provide family counseling treatment programs. In addition, suggestions and limitations such as customized case management services for each preventive case for the elderly at potential risk of Internet addiction and depression were presented.
Family Planning Operations Research: A Book of Readings
Authors: Foreit James R. , Frejka Tomas
Published: June 2023

For as long as there have been family planning programs, there has been family planning research. At the theoretical level, researchers examine the effect of fertility on health and socioeconomic development and study the determinants of fertility for individuals and populations. At the policy level, studies explore the role of family planning programs in modifying fertility and health. The development of new contraceptives is accompanied by clinical and pre-introductory trials in program settings. Surveys measure changes in contraceptive use and fertility, and the results are used to make decisions affecting programs. Finally, programs themselves carry out operations research (OR) to improve service delivery. This book provides an overview of how OR is used by family planning programs. The readings illustrate many of the major issues and topics that have benefited from OR, as well as many of the research designs encountered among OR studies. The book also provides information about the problems that programs and researchers encounter in carrying out OR and the challenges faced in translating research findings into changes in day-to-day program operations.

Authors: Al-Mukhtar Ramiz
Published: June 2023

Background: Laparoscopic sleeve gastrectomy is becoming one of the most common procedures performed for the treatment of morbidly obese patients in the last few years until now.Objectives: This type of surgery needs to be evaluated regarding the various techniques used and the possible post-operative complications with the exact methods of treating them.Patients and methods: A retrospective study was conducted on 240 consecutive morbidly obese patients over a period of 3 years (Feb 2011- Mar 2013) in the Saint Raphael Centre of morbid obesity with an average patient body mass index of 45 (35 - 61). They all underwent LSG, and the decreased weight resulting from surgery was analyzed regarding early and late complications. In 40 of the 240 patients, the gastric band was removed 4 weeks prior to the sleeve operation.Results: Intraoperative difficulties (difficult endotracheal intubation in 7 patients, difficult ports insertion in 6 patients, opening of the staple line in one patient and a bleeding from short gastric vessels in 2 patients). Only 5 patients developed primary haemorrhages (within the first 24 hours post operatively) from the staple line three of them were treated conservatively and the other 2 patients were returned to the theater, no anastomotic leakage or stricture, and no mortality. During a median follow up of 10.6 months (range of 1-3 months), the excess BMI lost reached 52+-23%, and the BMI decreased from 45 +-5 to 33 +- 5 kg/m2. Patient satisfaction scores (1-4) at least one year after surgery was 3.5 +- 0.7.Conclusion: The early results achieved by following the above outlined surgical steps in 240 consecutive patients who underwent LSG indicates show that this type of morbid obesity surgery is an effective, safe and worthwhile choice for morbidly obese patients as a first treatment option, although long-term results are still pending.
Resistance Training Maintains White Matter and Physical Function in Older Women with Cerebral Small Vessel Disease: An Exploratory Analysis of a Randomized Controlled Trial
Authors: Oh Jean , Crockett Rachel A. , Hsu Chun-Liang , Dao Elizabeth , Tam Roger , Liu-Ambrose Teresa
Published: June 2023

Background:

As the aging population grows, there is an increasing need to develop accessible interventions against risk factors for cognitive impairment and dementia, such as cerebral small vessel disease (CSVD). The progression of white matter hyperintensities (WMHs), a key hallmark of CSVD, can be slowed by resistance training (RT). We hypothesize RT preserves white matter integrity and that this preservation is associated with improved cognitive and physical function.

Objective:

To determine if RT preserves regional white matter integrity and if any changes are associated with cognitive and physical outcomes.

Methods:

Using magnetic resonance imaging data from a 12-month randomized controlled trial, we compared the effects of a twice-weekly 60-minute RT intervention versus active control on T1-weighted over T2-weighted ratio (T1w/T2w; a non-invasive proxy measure of white matter integrity) in a subset of study participants (N = 21 females, mean age = 69.7 years). We also examined the association between changes in T1w/T2w with two key outcomes of the parent study: (1) selective attention and conflict resolution, and (2) peak muscle power.

Results:

Compared with an active control group, RT increased T1w/T2w in the external capsule ( p = 0.024) and posterior thalamic radiations ( p = 0.013) to a greater degree. Increased T1w/T2w in the external capsule was associated with an increase in peak muscle power ( p = 0.043) in the RT group.

Conclusion:

By maintaining white matter integrity, RT may be a promising intervention to counteract the pathological changes that accompany CSVD, while improving functional outcomes such as muscle power.
Rigorous derivation of the Fick cross-diffusion system from the multi-species Boltzmann equation in the diffusive scaling
Authors: Briant Marc , Grec Bérénice
Published: June 2023

We present the arising of the Fick cross-diffusion system of equations for fluid mixtures from the multi-species Boltzmann equation in a rigorous manner in Sobolev spaces. To this end, we formally show that, in a diffusive scaling, the hydrodynamical limit of the kinetic system is the Fick model supplemented with a closure relation and we give explicit formulae for the macroscopic diffusion coefficients from the Boltzmann collision operator. Then, we provide a perturbative Cauchy theory in Sobolev spaces for the constructed Fick system, which turns out to be a dilated parabolic equation. We finally prove the stability of the system in the Boltzmann equation, ensuring a rigorous derivation between the two models.
Health literacy and empowerment in the COVID-19 era
Authors: Smith Sandra A. , Carbone Elena T.
Published: June 2023

The COVID-19 pandemic presented a teachable moment to empower citizens to assess and apply information to protect their health by promoting critical health literacy. Most Americans took preventive measures, suggesting some overall increase in critical health literacy around infectious disease. Simultaneously, however, a torrent of misinformation, disinformation and malinformation intentionally buried facts, sewed doubt and confusion, promoted lies and conspiracies, and undermined health authorities and institutions. The authors discuss how this ‘infodemic’ rose from previously localized, unconnected anti-vaccination, anti-government, and anti-science groups galvanized by the pandemic. Prominent politicians seeking political gain lent the power of their offices to the movement, layering a ‘polidemic’ onto the infodemic and overwhelming inconsistent public health messaging. Even those with strong health literacy skills were challenged. Millions were misled to over-confidently self-manage their risk, revealing the possibility and perils of empowerment in the absence of critical health literacy skills – negative empowerment. The roots of resistance to the government response to COVID-19, and conditions that fostered its influence are examined, followed by recommendations to position health literacy scholars and practitioners to better meet communication challenges and opportunities in future crises.
Traffic sign detection and recognition based on multi-size feature extraction and enhanced feature fusion module
Authors: Zhang Yongliang , Lu Yang , Zhu Wuqiang , Wei Xing , Wei Zhen
Published: June 2023

Deep learning has dominated the research field of traffic sign detection, but the traffic sign detection algorithms based on deep learning have difficulty in solving the two tasks of localization and classification simultaneously when performing traffic sign detection on realistic and complex traffic scene images, and the images or the types of traffic signs provided by the public dataset used by the relevant algorithm cannot meet the situations encountered in realistic traffic scenes.To solve the above problems, this paper creates a new road traffic sign dataset, and based on the YOLOv4 algorithm, designs a multi-size feature extraction module and an enhanced feature fusion module to improve the algorithm’s ability to locate and classify traffic signs simultaneously, in view of the complexity of realistic traffic scene images and the large variation of traffic sign sizes in the images. The experimental results on the newly created dataset show that the improved algorithm achieves 83.63% mean Average Precision (mAP), which is higher than several major object detection algorithms based on deep learning for the same type of task at present. The newly created dataset in this paper is publicly available at https://github.com/zhang1018/Traffic-sign-dataset-for-public.
A new monitoring approach of time-varying and nonlinear processes with application to penicillin fermentation process
Authors: Xie Ying , Hu Fanchao , Liu Xuewei , Zhai Lirong
Published: June 2023

In the actual production process, time-varying and nonlinear problems are numerous important problems to be considered, in view of these problems, a process monitoring approach based on locally weighted probabilistic kernel principal component analysis (LWPKPCA) is proposed. First, the method selects the normal process data with a high similarity to the test samples as training data of the local model, and continuously updates the local model according to the test samples to build an accurate time-varying model. Second, by weighting the data of different importance, the role of data similar to test samples in the modeling process is strengthened. Third, the LWPKPCA model is applied to process monitoring, the monitoring indicators are established in a high-dimensional space and used to detect faults. Finally, on the basis of LWPKPCA, the penicillin fermentation process (PFP) is taken to evaluate the monitoring performance of the proposed methods. According to the comparison of the experiment results, the detection rate and accuracy rate of the LWPKPCA method is considerably better than those of probabilistic principal component analysis and probabilistic kernel principal component analysis methods. The results demonstrate that the proposed method is suitable for processing time-varying data with nonlinear characteristics, and the LWPKPCA process monitoring method is effective for improving the performance of fault detection.

With the implementation of China’s “two-carbon” target strategy, the status of renewable energy in the power system is gradually improving. In order to improve the carbon emission control level of power grid, it is necessary to predict the peak carbon emission of power grid. A prediction method of grid carbon emission peak based on energy elasticity coefficient is proposed. A time series model of grid carbon emission samples was constructed, and a combination of combinatorial sorting and machine learning was used to reconstruct the time series of grid carbon emission peaks. Based on the results of time series reconstruction, feature extraction and classification training of grid carbon emission peak are carried out, and the measurement error correction of grid carbon emission under the constraint of energy consumption elasticity is realized. Combined with the association rule mining method, the fusion processing of grid carbon emission peak samples under the elastic constraint of energy consumption is realized. Through characteristic detection and fusion processing of energy consumption elasticity coefficient, the reconstituted carbon emission samples of power grid constrained by energy consumption elasticity were reconstructed, and the peak carbon emission of power grid was predicted. The simulation results show that this method has high accuracy and convergence in predicting the peak carbon emission of power grid, and improves the error correction ability in the prediction process.
A novel fault tolerance based load balancing technique in cloud computing
Authors: Lei Chang
Published: June 2023

Cloud computing has emerged as one of the most promising technologies for meeting rising computing needs. However, high-performance computing systems are more likely to fail due to the proliferation of components and servers. If a sub-system fails, the entire system may not be functional. In this regard, the occurrence of faults is tolerable using an efficient fault-tolerant method. Since cloud computing involves storing data on a remote network, system failures and congestion are the most common causes of faults. The paper presents a new approach to adopting a fault-tolerant mechanism that adaptively monitors health to detect faults, handles faults using a migration technique, and avoids network congestion. With the advantage of the Ant Colony Optimization (ACO) algorithm and active clustering, the load is distributed evenly in data centers. Simulation results indicate that our algorithm outperforms previous algorithms regarding total execution time and imbalance degree up to 10% and 17%, respectively.
Multi-agent based coalition formation of prosumers in microgrids using the i* goal modelling
Authors: Sumesh Sreenithya , Krishna Aneesh
Published: June 2023

In this paper, we discuss the role of microgrids as a “prosumer”. Microgrids are used to provide locally generated power (energy), and this concept is becoming increasingly prominent with time. Microgrids have added economic value when assuming the role of “prosumer” or “group of prosumers”. A new outlook in managing prosumers connected to the energy sharing network has led to the creation of prosumer coalition groups, which can subsequently manage numerous goals in microgrid energy systems. For achieving prosumer energy goals, Goal-Oriented Requirements Engineering (GORE) is deployed in this work. Hence, the purpose of this research is to develop prosumer coalition-GORE artefacts, strategising GORE players, modelling non-functional requirements and ensuring sustainable requirements engineering management in the microgrid energy system. In this research, an i* goal model has been used to design a payoff function based on the game theory concept. The key to the pricing function is its fair distribution of payoffs depending on their surplus energy generation, thus providing optimum satisfaction to the buyer. With the objective of maximising the profits earned by prosumers through intra-microgrid energy trading, this paper also designs multi-objective functions to provide optimal value by using the i* goal model. By integrating Java with the IBM CPLEX optimisation tool, a simulation model based on the proposed method was developed and analysed. The results show that the proposed approach yields better outcomes when meeting the requirements of fairness and efficiency, reducing the intermittency effect of generation through renewable resources.
Reason-able embeddings: Learning concept embeddings with a transferable neural reasoner
Authors: Adamski Dariusz Max , Potoniec Jędrzej
Published: June 2023

We present a novel approach for learning embeddings of ALC knowledge base concepts. The embeddings reflect the semantics of the concepts in such a way that it is possible to compute an embedding of a complex concept from the embeddings of its parts by using appropriate neural constructors. Embeddings for different knowledge bases are vectors in a shared vector space, shaped in such a way that approximate subsumption checking for arbitrarily complex concepts can be done by the same neural network, called a reasoner head, for all the knowledge bases. To underline this unique property of enabling reasoning directly on embeddings, we call them reason-able embeddings. We report the results of experimental evaluation showing that the difference in reasoning performance between training a separate reasoner head for each ontology and using a shared reasoner head, is negligible.

Published: June 2023

Recent research has shown that ceilings play a significant role in enhancing thermal comfort and indoor air quality within the built environment, particularly in tropical climates. However, this can result in excessive energy consumption as traditional methods struggle to maintain a comfortable temperature indoors. To address this issue, the objective of the research was to develop a cost-effective, thermally insulated ceiling sheet system that reduces the operational energy required for temperature control and ensures consistent temperatures within enclosed spaces. The researchers devised an insulation panel using readily available natural fibers, specifically coconut coir, which possesses excellent insulation properties. The proposed system was modeled and compared with two other scenarios: Calicut roofing without any insulation and Calicut roofing with Expanded Polystyrene Insulation (EPS). The results of the study demonstrated that the single-layer insulation system achieved a remarkable 65% reduction in temperature variation when compared to the traditional roofing system. These findings highlight the efficacy of the proposed low-cost, thermally insulated ceiling sheet system in improving indoor thermal comfort and reducing energy consumption for temperature regulation in tropical climates.
