Authors:   The Tourism Sciences Society Of Korea, Choi Min-Kyung , Lee Hoon
Published: August 2022

Tourists are increasingly interested in modern cultural heritage sites because they have historical significance and engage living spaces from everyday life. People nowadays seek an authentic life to liberate themselves from negative emotions. Tourists recover from them and live with vitality in everyday life after participating in a tourism experience. Tourists who visit heritage sites are affected by authenticity. This study aimed to investigate the impact of perceived authenticity, experience, and existential authenticity on modern cultural heritage sites in order to better understand this phenomenon. Perceived authenticity was defined specifically as perceived judgment based on objective authenticity. Furthermore, the researcher established the hierarchy for them in the context of the experience perceived by on-site visitors. The research site was Gunsan's cultural heritage sites, and a questionnaire survey was used. The total number of questionnaires collected was 330, and 289 were analyzed. Regression analysis confirmed the effect of variable relationships and the partial mediating effect of experience. This study employed empirical analysis to assess perceived authenticity. It academically constructs and expands on previously limited concepts. Based on the findings, this study provides practical recommendations for improving existential authenticity and experiential tourism content. Finally, the qualitative growth of heritage tourism and change can provide meaningful implications.

Relevance Currently, frequency converters with diode rectifiers are very often used in conveyor drive systems. However, frequency converters generate current harmonics, adversely affecting the quality of the network and the durability of electrical equipment. In the electric drive system, the induction motor consumes the reactive power of the source, which causes losses in the network and reduces the power factor at the input of the converter. Therefore, for the electric drive system, it is necessary to analyze methods for improving the power factor and reducing harmonic distortion of the current in the network. The reactor frequency converter has a simple structure but does not have high efficiency. A frequency converter with a multi-pulse rectifier will use multiple rectifier circuits in combination with a transformer to eliminate high order harmonics. The reactor frequency converter has a simple structure but does not have high efficiency. A frequency converter with a multi-pulse rectifier will use multiple rectifier circuits in combination with a transformer to eliminate high order harmonics. The active filter method will produce current waves of the same amplitude but opposite phase angle to the harmonics generated by the load, which eliminates most high-order harmonics and can compensate for reactive power. Aim of research Improving the energy efficiency of the conveyor electric drive with minimizing its impact on the quality of the electric power of the quarry network through the use of active rectifiers with a direct power control system in multi-inverter frequency converters. Research methods In this study, the following methods were used: the study of scientific literature, computer simulation performed in the MatLab software package. Results The frequency converters use active rectifiers with direct control of active and reactive power, the power factor is close to unity, and the energy exchange occurs in two directions between the motor and the network.

The surroundings of João Pessoa square have buildings and monuments of undeniable political, cultural, historical and artistic importance, some dating back to the beginning of the foundation of the city. The Court of the Justice and Jesuit set stand out, attracting a large flow of tourists. In the center of the square, the monument to João Pessoa was erected, formed by a granite that does not exist in situ in the municipality. Other varied and rare lytic types decorate these buildings internally. Its constructions, human settlements, uses of land and sea, among other apparatuses are consequences of certain natural conditions ideal for the creation of human labor, which resulted in the urban expansion of João Pessoa city. In this work an integrated evaluation was made between the diverse elements of the geodiversity and the heritage in question, through the analysis of documentation produced during the colonial period, in the form of texts, letters and iconographies and field work, since this relation still is practically without research and dissemination, in an interdisciplinary dialogue between geodiversity and culture.

Ecosystem services are a hotly debated topic in recent years; however, talking about the assessment of ecosystem services only makes sense when there are indicators that are demonstrably correlated with this aspect. This is because it becomes possible to diagnose, evaluate and promote public policies that are aligned with the demands, potentials and expectations for a given ecosystem. Given this, and the growing trend in the use of geotechnologies, this study sought to assess the panorama of research that has possibly studied landscape metrics applied to the assessment of the provision of ecosystem services in an integrated manner. To this end, a bibliometric analysis was carried out on the Scopus Platform using the following keywords: 'valuation of ecosystem services' and 'landscape metrics'. It was found that this topic is not yet complacent; and countries like the United Kingdom, China, Germany, Australia, Spain and the Netherlands have led the research. Especially for forest ecosystems, the gaps are still large, which demands research efforts to consolidate the best and provide solid knowledge bases for an effective management of these sensitive and highly specialized areas for humanity.

The search for sustainable cities has seen the Compact City as a better way to structure urban areas. This statement is corroborated by the fact that, among the guidelines proposed by the United Nations on the last Habitat Conference, there are several compact city principles. Given the importance of this model, this article presented an overview of its development, its main thinkers, the most relevant publications and the context in which the Compact City concept was developed, focusing on the importance of the thought and activity of the Townscape movement in the consolidation of the model since the end of the 1940’s. From the publications analyzed, one can recognize two phases in the concept’s evolution: a formative period (1940-1970), characterized by the search for an alternative to the postwar urban models; and a second moment (since the 1980’s), when the concept took its current form and started to be proposed as an answer to environmental problems and, secondarily, to other challenges of contemporary urbanization.
S-RLNC based MAC Optimization for Multimedia Data Transmission over LTE/LTE-A Network
Authors: Patil Veeresh , C. Keshavamurthy Sanjeev Gupta,
Published: August 2022

The high pace emergence in communication systems and associated demands has triggered academia-industries to achieve more efficient solution for Quality of Service (QoS) delivery for which recently introduced Long Term Evolution (LTE) or LTE-Advanced has been found as a promising solution. However, enabling QoS and Quality of Experience (QoE) delivery for multimedia data over LTE has always been a challenging task. QoS demands require reliable data transmission with minimum signalling overheads, computational complexity, minimum latency etc, for which classical Hybrid Automatic Repeat Request (HREQ) based LTE-MAC is not sufficient. To alleviate these issues, in this paper a novel and robust Multiple Generation Mixing (MGM) assisted Systematic Random Linear Network Coding (S-RLNC) model is developed to be used at the top of LTE MAC protocol stack for multimedia data transmission over LTE/LTE-A system. Our proposed model incorporated interleaving and coding approach along with MGM to ensure secure, resource efficient and reliable multiple data delivery over LTE systems. The simulation results reveal that our proposed S-RLNC-MGM based MAC can ensure QoS/QoE delivery over LTE systems for multimedia data communication.

Authors: Juan Shan Kutub Thakur, , Pathan Al-Sakib Khan
Published: August 2022

Now-a-days, social engineering is considered to be one of the most overwhelming threats in the field of cyber security. Social engineers, who deceive people by using their personal appeal through cunning communication, do not rely on finding the vulnerabilities to break into the cyberspace as traditional hackers. Instead, they make shifty communication with the victims that often enable them to gain confidential information like their credentials to compromise cyber security. Phishing attack has become one of the most commonly used social engineering methods in daily life. Since the attacker does not rely on technical vulnerabilities, social engineering, especially phishing attacks cannot be tackled using cyber security tools like firewalls, IDSs (Intrusion Detection Systems), etc. What is more, the increased popularity of the social media has further complicated the problem by availing abundance of information that can be used against the victims. The objective of this paper is to propose a new framework that characterizes the behavior of the phishing attack, and a comprehensive model for describing awareness, measurement and defense of phishing based attacks. To be specific, we propose a hybrid multi-layer model using Natural Language Processing (NLP) techniques for defending against phishing attacks. The model enables a new prospect in detection of a potential attacker trying to manipulate the victim for revealing confidential information.

Modern communication system use cryptography algorithm to ensure data still confidentiality, integrity, and authentic. There is a new vulnerability in a cryptographic algorithm when implemented on a hardware device. This vulnerability is considered capable of uncovering a secret key used in a cryptographic algorithm. This technique is known as a power analysis attack. Previous and other research introduces countermeasure to countering this new vulnerability. Some researchers suggest using logic level with encoding the AES. The countermeasure using logic is meager cost and efficient. The contribution of this paper is to analyze CPA on encryption device that has been given logic level countermeasure. Our finding of this paper is the use of encoding with one-hot masking technique does not provide the maximum countermeasure effect against CPA-based attacks. In this research, CPA attack can be successfully revealing the AES secret-key
Distributed Channel and Power Level Selection in VANET Based on SINR using Game Model
Authors: Sulistyo Selo , Alam Sahirul
Published: August 2022

This paper proposes a scheme of channel selection and transmission power adjustment in Vehicular Ad hoc Network (VANET) using game theoretic approach. The paradigm of VANET enables groups of vehicles to establish a mesh-like communication network. However, the mobility of vehicle, highly dynamic network environment, and the shared-spectrum concept used in VANET pose some challenges such as interference that can decrease the quality of signal. Channel selection and transmit power adjustment are aimed to obtain the higher signal to interference and noise ratio (SINR). In this paper, game theory is implemented to model the channel and power level selection in VANET. Each vehicle represents the player and the combination of channel and power level represents the strategy used by the player to obtain the utility i.e. the SINR. Strategy selection is arranged distributively to each player using Regret Matching Learning (RML) algorithm. Each vehicle evaluates current utility obtained by selecting a strategy to define the probability of that strategy to be selected in the next time. However, RML has a shortcoming for using assumption that hard to be implemented in real VANET environment. Therefore modification of RML devised for this application is also proposed. The simulation model of channel and power level selection is build to evaluate the performance of the proposed scheme. The results of simulation display the improvement of VANET performance in term of SINR and throughput from the proposed scheme.
Damping Modification Factors for Horizontal and Vertical Acceleration Spectra from Offshore Ground Motions in the Japan Sagami Bay Region
Authors: Hu Jinjun , Liu Mingji , Tan Jingyang
Published: August 2022

Damping modification factors (DMFs) are used to scale the 5%-damped response spectra for the seismic design of structures with different damping ratios. However, there is no DMF model for offshore engineering response spectra at present. Using 892 offshore and 4033 onshore ground-motion records from the Kyoshin net, the difference between offshore and onshore DMFs are revealed by DMF ratios and t tests and whether site conditions need to be incorporated in offshore DMF models are determined. The between-event residual distribution shows that DMFs depend on the focal depth. The results show that the DMFs from the offshore and onshore ground motions differ significantly for most spectral periods, and the impact of the site condition on offshore DMF is very slight. The offshore DMF models for the horizontal and vertical acceleration spectra from the Japan Sagami Bay region are presented from spectra of 34 spectral periods and 10 damping ratios, in which only spectral periods and damping ratios are considered as variables. The uncertainty in the DMF model mainly depends on the path and site effects, and the standard deviations of DMFs for the vertical component are slightly less than those for the horizontal component. All standard deviations are modeled by a set of quadratic functions related to damping ratios. A comparison between the offshore DMF model in this study and those derived from onshore ground motions indicates that the differences are significant. The spectra from the Hu et al. (2020) study for offshore ground motions adjusted by the DMF models are used as our example applications.
The MyShake App: User Experience of Early Warning Delivery and Earthquake Shaking
Authors: Patel Sarina C. , Allen Richard M.
Published: August 2022

MyShake is a free citizen science and public safety smartphone application that delivers the United States ShakeAlert program’s Earthquake Early Warning to the public in the states of California, Oregon, and Washington. Although smartphone notifications have long been a component of the ShakeAlert warning delivery plan, very little data has been published on the efficiency and accuracy of such communication. MyShake records timestamps in its alert processing system, including the time it takes for a phone to receive and acknowledge an alert’s delivery. We use data collected for five representative earthquakes—three in urban regions, two rural events—since October 2019 to assess MyShake alert delivery latencies and ground-motion prediction accuracy. For these events, MyShake was capable of efficiently processing and delivering warnings. For the smaller urban events that occur beneath the target population, about half of recipients received a warning before the estimated onset of the S-wave, and up to 90% received an alert prior to experiencing peak shaking. When earthquakes occur further from populated areas, the warning time naturally increases. Smartphone acceleration recordings can also be used to quantify the user experience during earthquakes because they are colocated with people. A review of waveforms collected by MyShake shows a systematic amplification of shaking recorded by smartphones relative to nearby traditional stations. The median amplification calculated using records from all five sample events is a factor of 3.1. Once this correction is applied, MyShake peak accelerations are generally consistent with the distribution of shaking intensities in the U.S. Geological Survey ShakeMap product, whereas also showing some individual sites with substantial amplification and de-amplification. In addition to delivering early warnings, therefore, MyShake provides a waveform observation dataset to densify shaking intensity observations and thereby improve our understanding of earthquake effects and evaluate the accuracy of ShakeAlert’s alerting regions.

Published: August 2022

One of the great disasters on earth is forest fires. Attempts to detect disaster events have been made with the help of monitoring technology. However, the problem is that the sensor is less responsive to detecting the presence of fire. Furthermore, sending information about fire incidents throughout the forest cannot use the existing communication platform. Therefore, we designed a forest fire monitoring system using LoRa. This technology is based on wireless which can transmit data across the forest. To detect the presence of fire, Arduino Uno is used as a microcontroller that regulates input from the AMG8833 sensor and GPS Ubox 6M. The experiment shows that the AMG8833 sensor is more sensitive in detecting the presence of fire as the catch range changes between 3 to 10 meters. In that distance range, hotspots were detected 19.25 oC to 122.5 oC when testing the sensor node is done. The monitoring system developed in this study demonstrated that sensor nodes and gateways could communicate up to 500 meters apart with a signal quality of -134 dBm. The best LoRa configuration mode for this communication capability is a Bandwidth of 250, a Code Rate of 4/5, and a Spread Factor of 10.One of the great disasters on earth is forest fires.

Published: August 2022

Dengue fever is a worldwide issue, especially in Yemen. Although early detection is critical to reducing dengue disease deaths, accurate dengue diagnosis requires a long time due to the numerous clinical examinations. Thus, this issue necessitates the development of a new diagnostic schema. The objective of this work is to develop a diagnostic model for the earlier diagnosis of dengue disease using Efficient Machine Learning Techniques (EMLT). This paper proposed prediction models for dengue disease based on EMLT. Five different efficient machine learning models, including K-Nearest Neighbor (KNN), Gradient Boosting Classifier (GBC), Extra Tree Classifier (ETC), eXtreme Gradient Boosting (XGB), and Light Gradient Boosting Machine (LightGBM). All classifiers are trained and tested on the dataset using 10-Fold Cross-Validation and Holdout Cross-Validation approaches. On a test set, all models were evaluated using different metrics: accuracy, F1-sore, Recall, Precision, AUC, and operating time. Based on the findings, the ETC model achieved the highest accuracy in Hold-out and 10-fold cross-validation, with 99.12 % and 99.03 %, respectively. In the Holdout cross-validation approach, we conclude that the best classifier with high accuracy is ETC, which achieved 99.12 %. Finally, the experimental results indicate that classifier performance in holdout cross-validation outperforms 10-fold cross-validation. Accordingly, the proposed dengue prediction system demonstrates its efficacy and effectiveness in assisting doctors in accurately predicting dengue disease.

A case of anorexia nervosa whose body image deteriorated after being weighed with classmates at school
Authors: KAYMAZ Nazan , UZUN Mehmet Erdem
Published: August 2022

Anorexia nervosa is an eating disorder characterized by a heightened desire to have a lean body structure that leads to an extreme fear of becoming fat. The patients with this disorder have a severely impaired perception of their bodies. Negative behaviors and attitudes in peer communication may hugely impact the affected individual at every stage of this disorder. The level of peer communication quality could be shaped by the conditions prevalent in the school, particularly the approaches undertaken by the educators and the staff at school. However, it would be incorrect to state that wrong communication styles adopted by the friends of an individual or unsuitable conditions in the school environment alone would be sufficient for the development of anorexia nervosa in adolescents. A 16-year-old girl with anorexia nervosa was followed up for 1.5 years after the diagnosis of the disorder, a period during which she had begun exhibiting improvement in her condition. However, her symptoms reappeared after she underwent height and weight measurements at school during the physical education and sports class to determine her physical health. This case is presented (1) to remind that anthropometric measurements are personal data and (2) to emphasize that it would be appropriate to provide privacy in this respect at schools.

Published: August 2022

Captopril is an Angiotensin-Converting Enzyme inhibitor (ACE Inhibitor) used for the treatment of hypertension. It has been reported that the duration of antihypertensive action after a single oral dose of captopril is only 6–8 h, specific absorption in the stomach, stable at acidic pH and degraded at high pH. These indicate a promising potential of the captopril hollow microspheres system as an alternative to the conventional dosage form. The preparation method used in this study is non-aqueous solvent evaporation. This study aims to determine the amount of ethyl cellulose (EC) and stirring speed to produce hollow microspheres having entrapment efficiency (EE), buoyancy and particle size maximum. Determination of the optimum hollow formula microspheres captopril uses a design factorial of two factors at two levels. The factors used in this study were the amount of EC and stirring speed, while the observed response was EE, buoyancy and particle size. The chosen optimum formula will be verified and characterized (yield, SEM, FT-IR). Formula AB was the optimum formula with EE 90.68%, buoyancy 81.52% and particle size 267.10µm. The verification obtained results in accordance with the prediction of the Design-Expert software. The characterization results obtained a yield value of 98.33%, with a spherical shape, uneven surface morphology, and hollow core. The results of FT-IR analysis showed that there was no interaction between the drug and polymer used in the formulation.

Natural circulation systems (NCS) are prone to instabilities, they are more unstable compared to forced circulation systems as a result of the low driving head and nonlinearity of the system. Flashing instability is prominent in these systems at low pressure due to the presence of a long nonheated riser to enhance the driving force. RELAP5 code has been identified as one of the Best Estimate (BE) codes used in the analysis of the systems. The studies by different authors showed that the effects of system parameters on instability generally have gained the attention of researchers in recent years. However, these studies have not discussed how these parameters prevent or enhance the commencement of flashing instability. This we sought to achieve in this work, by zeroing in on the inception of flashing instability, by comparing what happened at different heat fluxes. The objective of this work is to investigate the effects of system parameters on the inception of flashing instability in a natural circulation system using the RELAP5 code. With the increase in inlet subcooling and height of the riser, flashing moved to the outlet of the riser, stabilizing the system. However, an opposite effect was observed with an increase in the inlet resistance.

Introduction: The implementation of the Occupational Health and Safety system in industry aims to create a workplace that is safe, healthy, and free from environmental pollution so that it minimizes the probability of occupational accidents and illness. The arrangement of goods and comfortable work environment can affect labour productivity. Creating an orderly and comfortable working environment can be manifested in a good Sort, Set, Shine, Standardize (5S) application. The purpose of this study is to describe the implementation of the 5S program in PT Albea Rigid and Packaging Surabaya. Method: This research was a descriptive qualitative research. The data used in this study were secondary data which were obtained from the EHS Department of PT. Albea Rigid Packaging Surabaya which were later analyzed using several theoretical references. Variables in this research were observation of Sort, observation of Set, observation of Shine, observation of Standardize and observation of Sustain. The analyzed data were further interpreted and presented in a narrative form. Results: The results show that the implementation of 5S in the Injection Molding Production area of PT. Albea Rigid Packaging Surabaya, before the socialization, had a score of 16 points and after the socialization it increased to 40 points. Even though the score has increased, the implementation of the 5S was still not running optimally. Conclusion: The principle of Standardize still had the same score before and after the socialization, while for the other 3 principles, namely Sort, Set and Shine, there was an increase in points after the socialization.

Introduction: Work accidents can occur due to two factors, namely unsafe human behavior and unsafe environmental conditions. One of the unsafe human behavior is work fatigue. In addition, work fatigue can also reduce productivity so that it can have a bad impact on the company. This study aims to determine the strength of the relationship and the direction of the correlation between nutritional status and work postures with work fatigue on crane operators. Method: This research is included in the type of descriptive observational research with a cross-sectional approach. The sample of this study was taken using total sampling, namely all the population of 30 people. The independent variables in this study were nutritional status and body postures, while the dependent variable was work fatigue. The data were analyzed using the Spearman's correlation coefficient (Spearman rank's correlation coefficient) to see the value of the correlation coefficient. Results: The correlation coefficient between nutritional status and work fatigue was -0.169, which means there was a very weak relationship with a negative direction. Meanwhile, the strength of the relationship between work postures and work fatigue can be seen in the correlation coefficient of 0.671, which means there was a strong relationship with a positive direction. Conclusion: Workers with overweight and obese nutritional status wwere more relaxed at work and did not pursue daily targets so that the fatigue experienced was classified as moderate. In addition, poor work postures can cause severe work fatigue.
1,2-dihydroxynaphthalene as Biomonitoring of Occupational Exposure to Naphthalene
Authors: Budiman Erwanda Desire , Ilyas Muhammad
Published: August 2022

Introduction: Naphthalene is a chemical exposure found in various industries, including in the manufacture of phthalic anhydride, synthetic resins, lubricants, mothballs, and used as fuel additives. The exposure to naphthalene in humans has several detrimental health effects such as hemolytic anemia, kidney and liver disorders. Therefore, biological monitoring is needed as a health surveillance of naphthalene exposure. Generally, the biomonitoring examination carried out for this is naphthol in the blood. However, 1,2-dihydroxynaphthalene (1,2-DHN) is also known to be another major metabolite. Therefore, this literature review aims to determine whether 1,2-DHN can also be a reliable biomonitoring test on occupational exposure to naphthalene. Methods: PubMed, Proquest, and Google Scholar were used to conduct article searches. The articles were chosen based on predetermined inclusion and exclusion criteria. The selected articles were then critically appraised. Results: Four cross-sectional articles examining 1,2-DHN in the urine of naphthalene-exposed workers were selected and reviewed. There was a similar result from all selected articles that elevated levels of 1,2-DHN in the urine, indicating workplace exposure to naphthalene. Moreover, apart from having a strong correlation with 1- and 2-naphthol, 1,2-DHN also has a high sensitivity compared to these established metabolites. Conclusion: Based on the articles obtained, 1,2-DHN can be a reliable biological monitoring for workers exposed to naphthalene. However, further research is still needed on other industries exposed to naphthalene and is needed to ascertain the correlation between external and internal exposure to naphthalene.

Introduction: industrial mining activities have the highest prevalence of NIHL due to operating a heavy vehicle. Dozer is one of the heavy vehicles with a high noise level. Methods: This study was descriptive research about risk factors related to hearing loss of 28 dozer operators at PT. X. The risk factors consisted of demographic factors, working behavior (listening to music, smoking), noise levels were analyzed with hearing loss using STS. Interviews were conducted with the workers and company representatives. Hearing loss examination used an audiometric test to determine the STS of the operators with the result that positive more than 10 dB and negative at 10 dB or less. All the data is secondary. Results: noise level of all dozers exceeds the TLV (>85dB) operated for 10 hours a day and six days a week. Half of the dozer operators had STS (+) occurred at age 40 years and older, working for more than five years, not use the PPE or misused, the habit of listening to music and smoking. Conclusion: noise and demographic factors can increase the risk of hearing loss in dozer operators. The company must control by combining plywood, foam, tray, and coir material in the dozer cabin, which can reduce 31.94 dB and apply for PPE double protection.
