Background: The use of Antiretroviral Therapy (ART) has greatly improved the health and lifespan of people living with HIV, however, hepatic dysfunction has been associated with HIV. This study investigated the liver function biomarkers of women living with HIV and who are on ART. Methods: A cross-sectional study was conducted on HIV-positive pregnant women and HIV-positive non-pregnant women in Rivers State, Nigeria. A total of 330 women between 15-60 years participated in this study. HIV-negative pregnant and non-pregnant women served as a control to the test subjects. Sociodemographic data were collected using a well-structured questionnaire. Blood samples were collected for biochemical assay of the liver function biomarkers. The subjects were on Tenofovir-Lamivudine-Efavirenz (TLE) antiretroviral therapy. Data were analyzed statistically on IBM SPSS Version 25 using student’s t - test, ANOVA and compared using the Post hoc test. Results: The results obtained showed a significant increase at p ≤ 0.05 in the ALP, ALT and AST levels of both HIV-positive pregnant and non-pregnant women when compared to the control group. The serum TP level of HIV-positive pregnant women decreased in comparison to the control group. However, the decrease was not statistically significant at p ≤ 0.05. A statistically significant increase in the total protein level was observed in the HIV-positive non-pregnant women when compared to the control group. The albumin level in HIV-positive pregnant women had a statistically insignificant increase in comparison to the control group. HIV-positive non-pregnant women had a decreased level of Albumin at p ≤ 0.05 in comparison to the control group. Conclusion: The findings of the study suggest that the HIV-positive pregnant and non-pregnant women on ART are prone to adverse alterations in their liver function biomarkers in comparison to the control groups, hence they are vulnerable to liver dysfunction. Thus proper care and regular investigations should be carried out on HIV-positive women on ART.
Forest restoration, resources sustainable use and high-quality sustainable management
Authors: Zhongsheng Guo
Published: March 2023

As the economy develops and the population increases, there is an increasing demand for goods such as timber, food, medicine, and so on, and ecological services such as fresh water and the environment. Because goods and services produced by the original forest cannot meet the increasing need of people, so most of the original forest has become farmland, plantation, and grass. In the process of Forest restoration, a lot of exotic plants was introduced to produce special products and service. As exotic plants grow, vegetation declines, and crop failure will happen in dry years or resource waste in wet years. In order to solve these problems, Years of theoretical research and investigation in fixed positions have shown that there is a soil water resources use limit by plants and the soil water vegetation carrying capacity in the process of vegetation restoration. When the soil water resources in the range of the maximum infiltration depth are equal to the soil water resources use limit by plants, the plant water relation enters the key period of plant water relation regulation. If existing plant density is more than the soil water vegetation carrying capacity in the key period of plant water relation regulation, the plant water relation has to be regulated on the soil water vegetation carrying capacity to get maximal yield and service and realize high-quality sustainable management of forest vegetation in a water shortage area.

Authors:   The Pharmaceutical Society Of Korea, Hwang Ye Jin , Kang Jae Seon
Published: March 2023

This study was conducted to investigate the regulatory effect of Indirubin on LPS-induced inflammation in macrophage. The morphologic changes were shown as widened cytoplasm or biased nucleus from the center of the cell when LPS activated macrophage. The changes in inflammation activity were also estimated with mRNA levels of cytokines under time elapse at 2, 4, 8, 12, and 24 hours after the 10 ng/mL LPS treatment. By measuring those proinflammatory (TNF-α, IL-1β) and anti-inflammatory (IL-10) cytokines at each time set, the relationship between morphologic change and inflammation activity was compared. The highest pro-inflammatory mRNA expression was observed at 2 hours after the LPS treatment, and this was inhibited by those Indirubin standard (Indirubin) and Chungdae extract (CDEX). The mRNA expression level in LPS treated cell was markedly reduced at 8 hours as well as the other groups. However, IL-10, the anti-inflammatory cytokines was not affected by those treatments. The results suggested that the level of inflammation related changes as time elapsed. The current observation that both Indirubin and CDEX are able to inhibit LPS-induced inflammation by reducing the production of inflammatory cytokines. Moreover, the current observation suggested that estimating anti-inflammatory effects should include time-dependent measurements as biomarkers.

Metastatic basal cell skin cancer with distant metastatic skeletal lesions: a clinical case report
Authors: Polyakov A. P. , Buharov A. V. , Miroshnichenko D. A.
Published: March 2023

Clinical cases of distant metastasis of basal cell skin cancer are extremely rarely described in the international publications. This is probably due to the specific locally advanced growth of this histological type of tumor, as well as to the improvement of radical treatment methods for this group of patients. However, despite the development of both diagnostic research methods and treatment tactics, a large number of patients, especially when the primary tumor is located on the face and neck region, choose less effective and not always radical methods of treatment. In turn, non-radical removal of the primary tumor leads not only to difficulties in local control of the disease, but also to lymphogenous, as well as hematogenous spread of tumor cells and the manifestation of systemic metastasis.

In the article, we present a clinical case of metastatic basal cell skin carcinoma of the periorbital region with lesions of the bones of the skeleton, namely the thoracic vertebrae manifested 11 years after the detection of the primary tumor.

Salivary gland carcinomas is a rare family of neoplasms with different histological characteristics and biological behavior. Treatment regimens have remained virtually unchanged for decades, leaving the leading role for surgical treatment and radiation therapy. However, a special place in the salivary gland carcinomas group is occupied by adenoid cystic carcinoma, which is quite often characterized by a recurrent and / or metastatic course with the use of chemotherapy as the main option in treatment. It is worth noting the fact that the results of standard chemotherapy regimens show unsatisfactory results, respectively, with recurrent or metastatic adenoid cystic carcinoma, treatment options are minimal. Accordingly, there is a need to study new therapeutic methods for the treatment of this disease. In this situation, high hopes were placed on targeted therapy, in particular, the family of epidermal growth factor receptors, c-Kit are the most frequently studied molecular targets. Due to the rare occurrence of adenoid cystic carcinoma, the number of cases of using targeted therapy for analysis is relatively small, so each clinical observation is of particular value. The following is a clinical case of treatment of recurrent adenoid cystic carcinoma using a personalized treatment approach.

Aim. To describe the clinical observation of the use of targeted drugs in recurrent or metastatic adenocystic cancer of the salivary glands.

Published: March 2023

Over the last two decades, myoelectric signals have been widely used in fields including rehabilitation devices and human-machine interfaces. This study aimed to develop an algorithm for surface electromyography (sEMG) data acquisition utilizing low-cost hardware and validate its performance using English vowels as silent speech content. The sEMG data were collected from the three facial muscles of one healthy subject. The sEMG signals were pre-processed, and various time-domain and statistical features were extracted in real time. The raw data and features were then used to train and test three customized machine learning classifiers: k-nearest neighbor (KNN), support vector machine (SVM), and artificial neural network (ANN). All customized classifiers achieved almost equivalent accuracy rates of 0.83 ± 0.01 in recognizing the English vowels with an improvement of 27.27% (KNN), 3.75% (SVM), and 51.85% (ANN) utilizing the same low-cost data acquisition hardware. Our findings are substantially closers to the results of commercial hardware setups, which raise the possibility of potential usage of low-cost sEMG data acquisition systems with the proposed algorithm in place of commercial hardware setups for rehabilitation devices and other related sectors of human-machine interaction.

Published: March 2023

Scheduling cloud resources calls for allocating cloud assets to cloud tasks. It is possible to improve scheduling outcomes by treating Quality of Service (QoS) factors as essential constraints. However, efficient scheduling calls for improved optimization of QoS parameters, and only a few resource scheduling algorithms in the available literature do so. The primary objective of this paper is to provide an effective method for deploying workloads to cloud infrastructure. To ensure that workloads are executed efficiently on available resources, a resource scheduling method based on particle swarm optimization was developed. The proposed method's performance has been measured in the cloud. The experimental results prove the efficiency of the proposed approach in reducing the aforementioned QoS parameters. Several metrics of algorithm performance are used to gauge how well the algorithm performs.

The specifics of the anticoagulant therapy after radiofrequency ablation of the cavotricuspid isthmus have not been sufficiently studied, therefore, the recommendations for prescribing the anticoagulant therapy usually do not distinguish between atrial flutter and atrial fibrillation. In contrast to the case of atrial fibrillation, the effectiveness of the interventional treatment for typical atrial flutter reaches 90%. This procedure may save the patient from a long-term anticoagulant therapy in the absence of recurrence of typical atrial flutter. The decision to stop the anticoagulant therapy after successful radiofrequency ablation of the cavotricuspid isthmus should take into account the potential induction of atrial fibrillation in patients undergoing the interventional treatment. In addition to the CHA2DS2-VASc scale, which characterizes the patient's comorbidity, it is important to take into account the echocardiographic morphofunctional criteria to assess the risk of atrial fibrillation. Currently, this protocol is not regulated in the clinical guidelines. The analysis of the literature data and the authors' own experience allow us to conclude that the optimal time for stopping the anticoagulant therapy is a relapse-free period of 34 months after the radiofrequency ablation of the cavotricuspid isthmus, since it is at this time that the effectiveness of the interventional treatment can be objectified.

A Study on the Message Strategy for the Diffusion of Innovative Logistics System
Authors:   The Korean Logistics Research Association, Kim Kyung-Jin
Published: March 2023

This study explored how message strategies should be used in the case of innovations close to those vs. far from the existing logistics system. In Study 1, it was revealed that for far-off innovations, a message emphasizing connectivity with existing logistics systems is more effective, and for near innovations, a message emphasizing differentiation is more effective. This effect was limited to flexible thinking consumers. And in the case of far-off innovation, it matches the connectivity message, and in the case of near innovation, it matches the differentiation message because the risk perception of innovation is lowered each in that case. In other words, risk perception for innovation played a role as a mediator.
In Study 2, the role of risk perception in an innovative logistics system was explored in depth. For near innovations that only introduced RFID, message strategies that emphasized advantages were effective, and for far-off innovations that introduced both RFID and autonomous driving, message strategies that reassured risks were effective. The reason is that consumers have a high risk perception in the case of distant innovation. However, this risk management effect was limited to consumers who thought abstract and flexible. In addition, this risk management effect did not appear in an innovative logistics system for others other than for self.

Published: March 2023

Currently, the way suppliers and buyers find the best business partners on the supply chain is not far from simply focusing on low costs. This study aims to present a way to explore the optimal business partner to construct the best supply chain in consideration of supply chain risks, hidden costs, and opportunities to create added value. More specifically, the probability that a company finds an best business partner between regions or within regions is calculated and presented. In this study, we present a method of developing an index called a transaction possibility score using an artificial intelligence (deep learning) model to find a business partner as an best supplier.
We hope that the results of this study will not only explore the best business partners of each local company, but also help reorganize the local industrial structure in Korea.
Modeling of Ocean Wave Impacts on Crevassed Ice Shelves
Authors: Konovalov Yuri V.
Published: March 2023

The propagation of elastic flexural gravity waves through an ice shelf is modeled by two full 3D finite-difference elastic models that are coupled to a treatment of undershelf sea water flux. These models are based on the momentum equations written using the well-known differential equation form (model 1) and using an integro-differential form (model 2). The integro-differential form works with a variable that represents the vertical integration of the momentum equations from the current vertical position to the ice surface. The sea water flow under the ice shelf is described by a wave equation involving the pressure. Numerical experiments were undertaken for an ice shelf with spatially periodic crevasses. These experiments reveal that band gaps occur in the dispersion spectra in frequency bands that are consistent with Bragg’s law. It is found that the minimum threshold of crevasse depth must be exceeded for band gaps to arise. In particular, model 2, based on the depth-integrated momentum equations, provides the smaller averaged (in the considered range of the spatial periodicities of the crevasses) threshold value.

The first cause of cancer death was lung cancer among men and women. MicroRNAs are small noncoding regulatory RNAs with a length of 18–24 nucleotides. MicroRNAs could target more than 100 mRNAs, and they can affect many cellular processes. The objective of this study is investigating the role of miR-663a and miR-663b, in metastatic lung cancer patients compare with healthy people. The relationship between these microRNAs and chemoresistance was investigated through Real time polymerase chain reaction methodology used to determine the levels expression of miR-663a and miR-663b in the serum of 30 patients with metastatic lung cancer were treated with second line therapy versus 25 healthy individuals who follow up for one year. The resulted data showed that miR-663a expression was related to type of lung cancer and was significantly higher in metastatic squamous lung cancer group (P=0.012). While the expression of miR-663b was significantly correlated with the response to treatment, in which the expression of miR-663b was higher in the poor-response group (P=0.016). Inconclusion, this study showed that the high plasma level of miR-663a miR-663b may be related to chemoresistance in patients with metastatic lung cancer.

The aim of this study is to enhance the classification accuracy of rice varieties that are quite similar in external observation. In this study, 17 rice grain varieties popularly planted in Vietnam are classified with an Artificial Neural Network (ANN) and Convolutional Neural Network (CNN) models. The two CNN models (modified VGG16 and modified ResNet50) are based on pre-trained VGG16 and Resnet50 models. Two datasets are used in the experiments: a feature dataset extracted using an extended improved local ternary pattern (extended ILTP) method, and an image dataset generated with a data augmentation technique. The feature dataset was fed into the ANN, while the image dataset was fed into the CNN models. The highest classification accuracies of ANN, modified VGG16, and modified ResNet50 models are 92.82%, 96.41%, and 97.88%, respectively. The results show that the modified VGG16 and ResNet50 models significantly improved classification accuracy of the 17 varieties of rice. In addition, the experiments show that the dimensions of the image dataset can affect the performance of the CNN models. This research can be developed for applications of rice varieties classification and identification.

Published: March 2023

Educational data mining has advanced substantially within the past decade. These mining strategies lay out a plan for increasing overall academic enrollment. An increase in student enrolment, in general, would enhance academic performance. Therefore, the student enrollment pattern demands great attention, as it is a vital performance indicator of academic sustainability. In this paper, student enrolment data is pre-processed to obtain the gross enrolment ratio (GER). GER analysis and forecasting were performed using the state of art models Autoregressive Integrated Moving Average (ARIMA) and Long Short-Term Memory (LSTM). The purpose of this study is to analyze and compare student GER (time series data) using ARIMA (statistical methods) and LSTM (machine learning approach), forecast GER using a better method, and propose corrective measures for increasing student enrolment. The comparison results confirmed that LSTM out-performs ARIMA by an average of 0.1322% and 5.6% in both Root Mean Square Error (RMSE) and Accuracy. The predicted GER using LSTM for the academic year 2035 is 34.23% which is far lower than 50% which is targeted by Govt. of India. An in-depth analysis of student enrolment and GER in higher education in Mizoram was done, and corrective measures were proposed for enhancing GER.

Published: March 2023

Exercise promotes health in people with diabetes. Weight-bearing activities increase the risk of foot ulcers. Air-pressure shoes may relieve high plantar pressure. Nevertheless, no study has investigated whether air-pressure shoes affect the plantar foot. A repeated measures study design, with five healthy subjects were tested with three inner air pressures (80, 160, and 240 mmHg) and 20 minutes of walking to examine their effects on peak plantar pressure (PPP). PPP after walking was measured from the forefoot in the big toe (T1), first metatarsal head (M1), and second metatarsal head (M2). We used a one-way ANOVA to analyze the results. We found that after walking for 20 min, inner air pressure significantly affected plantar pressure in the M1 and M2 (P = 0.008 and 0.006, respectively). Regarding the inner air pressure effect, there was a significant difference in the M1 head between 80 and 240 mmHg (274.2 ± 35.6 kPa vs. 689.4 ± 106.3 kPa, P = 0.002) at 20 minutes of walking duration. Moreover, there was a significant difference in the M2 head between 80 mmHg and 240 mmHg (250.6 ± 30.1 kPa vs. 572.4 ± 87.3 kPa, P = 0.002) and 160 and 240 mmHg (396.6 ± 35.3.7 kPa vs. 572.4 ± 87.3 kPa, P = 0.050). This finding is significant because the higher inner air pressure shoes can increase plantar pressure compared to 80 mmHg inner air pressure. This study suggests that individuals who are at high risk of developing foot ulcers should wear shoes with an inner air insole (80 mmHg).
US-EU: shaping anti-Russian energy geopolitics
Authors: Prikhodko Oleg
Published: March 2023

The unfolding crisis of the world order reveals that a struggle for advantages in energy domain has acquired a distinctive geopolitical dimension. The rivalry between Russia and the West has come to the forefront of world politics. Energy became a frontline in the confrontation, and the Ukrainian conflict has spotlighted the trend. The article embraces a range of key issues of energy geopolitics involving Russia, the United States and Europe (EU). The US managed to develop a huge export potential of LNG as a result of revolution in technologies of shale gas and oil production. This capacity enables the US to play a crucial role in the West’s sanctions aimed at undermining Russian energy sector and shrinking Russia’s share in world markets. The United States and the EU focus their efforts on cutting off Russia’s energy ties with Europe and increasing American LNG supplies to European countries. This tectonic shift entails far-reaching strategic implications that will have a great impact on all parties involved.

Functional safety is a latent characteristic of hardware and software complexes (HSC) and is objectively characterized by consumer satisfaction with the HSC behavior. The paper considers an approach to solving project management problems based on the dynamic characteristics analysis of functional safety of conflict situations in the project management system. To analyze situations that arise when managing HSC projects, it is possible to use models known as system archetypes. The information essence of situations and the foundations of multi-aspect modeling are considered. The methodological basis of the research is a combination of dynamic models of parameters that characterize functional safety and structural models, corresponding to conflict situations that arise when ensuring the required level of functional safety. Examples of multi-aspect modeling of situations where manifestations of latent defects act as events are considered. As a result of the research, the information essences of situations are determined, the conceptual foundations of multi-aspect modeling of situations that arise when managing the HSC functional safety are proposed, and the basic stages of building a system of structural and dynamic models of situations at different stages of the HSC life cycle are identified. The results obtained can be used to make decisions about the advisability of making changes to the system structure for ensuring the functional safety of hardware and software complexes.
Ontology of human identification by face and body motions in video surveillance systems
Authors: Kolodenkova Anna E.
Published: March 2023

At the present stage of advancing information technology, the development of models and recognition methods by body movements and faces in video surveillance systems is a topical problem. This task is essential for security issues, especially at facilities with mass gatherings to counter a terrorism-related crime. The paper presents a classification of the main biometric features and parameters that characterize a potential violator. This classification has been developed for security control systems and access systems of enterprises. A block diagram of merging biometric data and violator recognition by body motions and face which can be used as the basis for the development of security control systems is proposed. The types of systems and methods of human recognition by body movements and face are considered, their advantages and disadvantages are revealed. It is noted that for accurate violator recognition under a set of biometric features, it is reasonable to use a combination of recognition methods which will allow to make the right decisions regarding the identification of a potential violator. This paper attempts to consider the main aspects related to human recognition by body movements and face in video surveillance in general, in contrast to well-known works devoted to individual biometric features.
New method for detecting and removing random-valued impulse noise from images

Published: March 2023

The paper proposes a method for detecting and removing impulse noise in images, which determines the similarity between pixels by distance and the difference in brightness values in the local detector window. An impulse noise model is considered, where distorted pixels take random values and also randomly appear in the image. Pixels identified as pulses are recovered with an adaptive median filter. The impulses are determined in the detector window, whose size is calculated in the Euclidean metric and increases with increasing noise intensity in the image. In the experimental part, we discuss visual differences between familiar methods and the one proposed herein on three images for three different impulse noise intensities. In the approximation of image fragments, it is seen that the proposed method copes with the task in the best way, which is also confirmed by numerical estimates of the quality of image reconstruction from impulse noise based on the peak signal-to-noise ratio and the structural similarity index. The proposed method can be used when solving problems of cleaning images under conditions of distorting impulses and for eliminating distortions caused by adverse weather effects, such as raindrops and snow.

Communication refers to a wide range of different behaviors and activities aimed at handing over information. The communication process includes verbal, paraverbal and non-verbal components, conveying the informational part of a message and its emotional part respectively. A complex analysis of all communication components makes it possible to evaluate not only the content, but also the situational context of what is being said, as well as to identify additional factors inherent in the mental and somatic state of the speaker. There are several methods of conveying a verbal message, among which are oral and gestural speech (such as the sign language and fingerspelling). Various forms of communication can be contained in multiple data transmission channels, such as audio or video channels. The review is concerned with video data analysis systems, as the audio channel is incapable of non-verbal components transmission that contribute supplemental details. The article analyzes databases of static and dynamic images and systems, developed to recognize the verbal component conveyed by oral and gestural speech, as well as systems that evaluate paraverbal and non-verbal components of communication. Challenges of designing such databases and systems are specified. Prospective directions in complex analysis of all communication components and its combinations for the most complete evaluation of messages are defined.

The Urban Growth and the Reorganization of Spatial Structure to the ‘Expressway City’ of Yongin in the 1970s
Authors:   HUFS Institute of History and Culture, Park Kyungyul
Published: March 2023

This article examines the urban growth of Yongin in the 1970s and the resulting changes in the spatial structure of the region. Yongin, a quiet rural area near Seoul, was converted into an urban space due to the construction of expressways. After the opening of the Seoul-Singal section of the Gyeongbu Expressway in 1968, Giheung-myeon(township), the western region of Yongin, was incorporated into the urban planning area of Suwon, which was geographically adjacent to it. Since then, the spatial structure of Giheung-myeon had been planned in connection with the Suwon City Plans. Following the conversion of the urban planning policy of the ROK government in 1974, the eastern part of the Gyeongbu Expressway was excluded from the Suwon urban planning area, however, it was able to establish Singal's own urban planning according to the “Guidelines for Urban Planning for Myeon-class Cities.” Since then, the Singal area had maintained the framework of urban planning designed in 1975 and reorganized urban spaces in line with the reality that industries in the region are growing. In the southern part of Giheung-myeon, tourist and residential areas were created near the expressway and Singal Reservoir. With the construction of the Giheung Housings and the Korean Folk Village, the southern Giheung became a representative tourist destination near Seoul. However, the area was easy to be a target for urban sprawl after then, because it was not included in either the Suwon urban planning zone or the Singal planning zone.
The Yongin-myeon area, at which the Yongin-gun(county) office was located and a city was previously formed, had undergone a transition to an industrial city since the opening of the Yeongdong Expressway in 1971. Yongin-gun designated industrial areas near the Yeongdong Expressway through urban planning, moved and relocated factories to the areas, and secured residential areas to create housing sites for factory workers. Since the establishment of the Reorganization Plan in 1974, the Yongin-myeon urban planning had maintained the structure of strengthening industrial functions and reorganizing urban areas to support them. Due to such urban growth, Yongin-myeon was able to form a single living sphere as a self-sufficient city, but it did not form a single urban area covering the Giheung region. The current disconnection and conflict between the eastern and western Yongin is also a result of such urban growth in the 1970s.

This study examined the changes caused by the expansion of the Mongol Empire to the military system, and in particular, focused on the changes of the military system after Kublai became the Great Khan. The trends and characteristics of the empire’s rule over China were reviewed in relation the military system. The Mongol Empire dominated Eurasia based on its military power, which was driven not only by the strength of individual soldiers but also the teamwork of Mingɣan-a unit of 1,000 households created based on the decimal system in the days of Genghis Khan. The empire expanded across Eurasia through military conquests led by the imperial elite force known as Keshig, Mongolian military, and Tanmachi comprised of foreign ethnic people. In the war against Jurchen during the reign of Ögedei, the Mongolian military recruited a significant number of Chinese, and categorized them as military households. From then on, the troops were divided into civil households and military households, and separately managed.
When the Mongolian Empire’s rule over China was converted to direct control under Qa’an, the military system was reorganized to establish a superior status for Mongol in China. In the early days of the Yuan, Kublai efficiently managed Mongol, Semu and Han troops, and formed a privy council to allow more rapid response to military crises, He gave his sons and grandsons royal titles and seals, and implemented policies to deploy them along border areas. This was an effective approach that reinforced the military’s inland monitoring while allowing prompt response to possible uprisings outside military powers. The Mongol Empire stationed troops in important areas after conquering China and Central Asia, and Kublai followed this tradition by stationing troops in North China and the newly conquered the Southern China. He stationed the Mongolian military in major areas alongside the Yellow river and Shandong province in the Northern China., and the Han Army and newly submitted the southern Song army, which lies alongside Yantze River and the Huai River. As such, the small number of Mongol rulers held dominant military positions in China. A review of the aforementioned policies shows that Mongol Empire adapted the military system to the new environment in China, and at the same time, largely retained the Mongol military tradition.
Christian pilgrims to Jerusalem and their perception of Muslims in the Later Middle Ages

Jerusalem was the Holy Land where Jesus Christ preached the gospel and was crucified, and for this reason, Christians made a pilgrimage to Jerusalem in search of the footsteps of Christ. However, from the 7th century, when Islam entered the Mediterranean, until the end of the Middle Ages, Jerusalem was always under Islamic rule, except for a brief period when the Crusaders took it back. Therefore, Christians who made a pilgrimage to Jerusalem were forced into contact with Muslims in the area.
Christian pilgrims who would make their pilgrimage to Jerusalem in the Later Middle Ages often had previous prejudices and distorted information about Islam. In general, pilgrims to Jerusalem in the Later Middle Ages were able to see and experience the Holy Land with their own eyes, but they reproduced well-established stereotypes by referring to previous literature and travel reports that had prejudices and negative perceptions about Islam.
Contact with local Muslims was generally prone to instilling a negative perception of them, especially because the pilgrims experienced discomfort during disembarkation at the port of Jaffa and an overnight stay in a cave, contact with Muslim donkey drivers asking for too much money, unexpected incidents on the way to Jerusalem, etc.
Pilgrims’ oral storytelling and the pilgrimage accounts they shared with those around them influenced the perception of Muslims. Although some laymen also wrote pilgrimage accounts, it was mostly priests who wrote them. In this sense, most of the pilgrimage accounts show a strong awareness of the church and the clergy’s attitude toward Islam. Negative perceptions such as hatred and antipathy towards Muhammad and Islam dominate most of the pilgrimage accounts.
Even people who made a pilgrimage to Jerusalem in the same year often spoke differently about their own experiences, and their perceptions of Muslims with whom they came in contact were not always consistent. In this regard, it should be said that the perceptions of Muslims appearing in the pilgrimage accounts in the Later Middle Ages did not have one perspective but varied. However, the Christian clergy’s stance on or perceptions of the Muslims were hostile.
Development Plan of Gangwon-do in the Mid to Late 1930s and the Colonial Industrialization of Samcheok

This study deals with the development process, its characteristics and limitations of Gangwon-do focusing on the Samcheok area from the mid-late 1930s to the early 1940s. Until the first half of the 1930s, Gangwon-do had ample room for development in forestry, fishery, and mining, but was recognized as an unexploited space due to transportation and geographical limitations. Then, after the mid-1930s, the possibility of development in Gangwon-do expanded in the policy of promoting agriculture and industry by the Japanese Government-General of Korea along with improving transportation infrastructure. At the same time, the Gangwon-do Development Committee was held in 1937, when Japan Empire demanded resource development and productivity expansion after the outbreak of the Sino-Japanese War. The Gangwon-do Development Committee was a meeting where it was declared that Gangwon-do could no longer remain an unexploited area, and it was a space where various interests of the people who would promote development overlapped.
Samcheok was the area where Gangwon-do’s development plan was most symbolically revealed. With the promotion of anthracite mining, chemical and cement industries, the industrialization of the Samcheok area was accelerated. However, the development and industrialization of the Gangwon region, centered on Samcheok, was a development from above centered on the empire and capital, revealing the limits of development that did not consider the lives of local residents.
New Vistas on Responsible Learning Analytics

The focus of ethics in learning analytics (LA) frameworks and guidelines is predominantly on procedural elements of data management and accountability. Another, less represented focus is on the duty to act and LA as a moral practice. Data feminism as a critical theoretical approach to data science practices may offer LA research and practitioners a valuable lens through which to consider LA as a moral practice. This paper examines what data feminism can offer the LA community. It identifies critical questions for further developing and enabling a responsible stance in LA research and practice taking one particular case — algorithmic decision-making — as a point of departure.

Features of accumulation and migration of technogenic radionuclides Cs-137 and Sr-90 in the tundra landscapes of the Russian Arctic (evidence from the Nes river basin, Kanin tundra)
Authors: Puchkov Andrey , Yakovlev E.
Published: March 2023

This article presents the results of studies of the lateral and vertical distribution of technogenic radionuclides Cs-137 and Sr-90 in peat and soils of the tundra territory of the Nenets Autonomous Okrug on the example of the Nes River basin (Kanin tundra). There are high levels of pollution density of Cs-137 and Sr-90 in the territory of the studied basin in comparison with the literature data. Such anomalies are associated with the mosaic nature of the lateral distribution of radionuclides, due to the geomorphological features of the territory. The results of calculating the isotopic ratios of two radionuclides showed that the main source of pollution can be global atmospheric fallout.
