Authors: Islam Zain ul , Khan Maria Anwar , Farooq Aiman , Aslam Saira
Published: October 2022

The present study aimed to examine the mediating influence of prosocial behavior between gratitude and mental health among adults. Sample size was justified from A-priori sample size calculator for structural equation modeling (Soper, 2021). The sample comprised of 420 adults who were purposefully selected with an age range of 18-26 years. Data were collected from major cities of Punjab (Lahore, Multan and Faisalabad) through online google form survey. Three questionnaires were employed; The Gratitude Questionnaire-GQ-6 (McCullough, 2013), depression and anxiety subscales from Mental Health Inventory-MHI-18 (Veit & Ware, 1983) and Prosocial Tendencies Measures-PTM (Carlo & Randal, 2002). After collecting the data for desired sample size, results were analyzed through SPSS (24.0), which revealed that there was a significant correlation between gratitude, prosocial behavior, and mental health among adults. Moreover, the results also found that there is a significant impact of gratitude on mental health through mediation of prosocial behavior among adults. This study will be helpful for adults, students, and consultants to recognize the precipitating and perpetuating factors to improve their mental health.

Published: October 2022

The structures of SiGenSc0/− (n = 3, 4) clusters were investigated by a combination of quantum chemical calculations, including the genetic algorithm (GA), the Perdew-Burke-Ernzerhof PBE functional, and coupled- cluster calculations (CCSD(T)). The geometrical structure, relative energy, harmonic vibrational frequency, adiabatic detachment energies were reported. The PBE functional is in good agreement with the CCSD(T) method. The stable structure of the SiGenSc0/− (n = 3, 4) clusters have a low spin multiplicity. The larger cluster can be formed by adsorbing the atom into the smaller cluster. The obtained results can contribute to the orientation of the nanomaterial formation for gas adsorption.
Monitoring 15-year land use/land cover change in the Vietnamese Mekong Delta
Authors: Nguyen Ho , Phan Van Phu , Nguyen Thi Hong Diep
Published: October 2022

Although land use/land cover (LULC) information plays a critical role in the maintenance of living standards with a balance among the environment, development, and sustainability, it remains little comprehensive understanding in the entire Vietnamese Mekong Delta (VMD). In this study, we used the random forest algorithm, Landsat images, ancillary and empirical reference data to carefully analyse the 15 years’ spatiotemporal changes (2005 - 2020) of LULC in the VMD region. Results show that agriculture has been the most dominant land, accounting for approximately half of the whole region during the fifteen years.Remarkably, most of the LULC categories have undergone dramatic transformation with the proportion of the wetland area decreasing from about 16% in 2005 to 5% in 2020, whereas that of the aquaculture area sharply increased from about 12% to 19% over the same period. Meanwhile, there was a marked increase in the area of perennial crops and built-up lands. These results of LULC maps and change detection helps understand the impact of past policies and the role of several factors such as socio-economic trends and environmental changes in this region.
Antibacterial activity of fruiting body extracts from Pycnoporus sanguineus mushroom
Authors: Tran Duc Tuong , Pham Ha Thanh Nguyen , Pham Van Hiep
Published: October 2022

This study aims to provide an in vitro evidence for the potential antibacterial activity of the ethanolic and aqueous extracts from fruiting bodies of the Pycnoporus sanguineus (L.: Fr.) Murrill mushroom via agar well diffusion method (concentration of extracts 250 mg/mL) and determination of the antibacterial activity and minimum inhibitory concentrations (MIC) of ethanolic and aqueous extracts from the fruiting bodies of this mushroom by agar dilution method (concentration range of 25; 12.5; 6.25; 3.125 and 1.5625 mg/mL). Ampicillin was used as a positive control for these assays. The results shows that the ethanolic and aqueous extracts from fruiting bodies of the P. sanguineus mushroom created the antibacterial halo ring (6 - 11 mm) on five bacteria strains (E. coli, P. aeruginosa, S. faecalis, S. aureus, and K. pneumoniae). The ampicillin created a fairly large antibacterial halo ring (19 - 34 mm) on three strains of E. coli, S. faecalis and S. aureus. The MIC values of two types of extracts from the fruiting bodies of the this mushroom on the five tested strains of bacteria were all ≤ 25 mg/mL. However, the MIC value of the aqueous extract (≤ 6.25 mg/mL) was lower than that of the ethanolic extract (≤ 25 mg/mL). The obtained results indicate that both ethanolic and aqueous extracts from fruiting bodies of the P. sanguineus were able to fight against the five bacteria strains. The P. sanguineus mushroom is potentially used as a natural herbal in antibacterial activity.

It is an explicit solver that expresses the solution as an integral over a Talbot curve, which is discretized with quadrature. First-order quadrature is currently implemented.
High-fidelity vortex-induced vibration of a wind turbine blade under extreme conditions
Authors: Lahooti Mohsen
Published: October 2022

Modern wind turbines are put to the stand-still state under certain conditions such as above-design wind speeds or scheduled maintenance. In such situations the blade is prone to experiencing the incoming wind flow with a very high angle of attack that could lead to massive separation and development and shedding vortices from the blade, resulting in an unsteady loading on the blade structure. Further, due to the large size and hence enhanced flexibility of modern wind turbine blades, this unsteady loading of the flow together with the aeroelastic response of the blade could result in vibration of the blade in such conditions which is known as the stand-still vibration. In this talk, the simulation results of the stand-still vibration of the NREL 5MW blade under high wind speed condition will be presented. Simulations are performed using a recently developed fluid-structure solver that has been implemented in the Nektar++ framework and is based on the coupling with the uDNS incompressible Navier-Stokes solver of Nektar++ and Geometrically-Exact composite beam (GECB) beam solver of SHARPy library.

Authors: Kirilov Kaloyan
Published: October 2022

High-fidelity spectral/hp element simulations require high-order, geometry conforming curvilinear meshes. This poses a significant challenge when arbitrary geometries are considered. Therefore, we will present the main capabilities of our high-order mesh generator, NekMesh. First, we will show our main mesh generation pipeline – from CAD to valid high-quality curvilinear mesh. This will be followed by an alternative industrial pipeline suitable for very complex geometries. Last, a demonstration of this pipeline will be performed and the current work on NekMesh will be outlined.
Using Nektar++ to Predict the Noise from Isolated and Installed Jets
Authors: Lindblad Daniel
Published: October 2022

Ever since jet airliners were introduced in the 1950s, jet noise has been a major concern for the airline industry. Today, the amount of noise produced by the turbulent jet is considerably lower than it was 70 years ago. Despite this, jet noise is still the dominant source of aircraft noise during take-off. Therefore, further reductions in jet noise are necessary to meet increasingly stringent noise certification tests, and thereby reduce the negative environmental impacts of aircraft noise. To date, most reductions in jet noise have been realized by increasing the diameter of the engine. This makes it possible to reduce the velocity of the jet, while at the same time keeping the thrust constant. A lower velocity does in turn lead to lower noise levels and better fuel efficiency. However, larger engines must also be placed closer to the wing in order to provide enough ground clearance. This leads to a new source of aircraft noise as the turbulent jet impinges on the wing: installed jet noise. In this talk, I will present some recent efforts on modeling isolated and installed jet noise using the high-order Nektar++ code.
Flows through Living Roughness
Authors: Monismith Stephen
Published: October 2022

Kelp forests, seagrass beds, and coral reefs are among the most productive, bio-diverse, and beautiful of marine ecosystems. Hydrodynamics plays a central role in their function, controlling mass transfer between the organisms and the overlying flow, setting patterns and rates of transport of larvae, and affecting the extent to which the environment (temperature, pH, etc.) in these nearshore systems are different from that of the adjacent ocean. Central to this interplay of physics and ecology is the fact that the resistance to flow provided by kelp plants, seagrasses, or corals is determined by the geometry and density of these “ecosystem architects”, behavior that is described by the dynamics of complex, canopy flows. I will present field observations of these flows drawn from a coral reef in American Samoa, a seagrass bed in Palau, and a kelp forest in Baja. In the first case, drag can be related explicitly to the reef geometry at cm scales. In the second case, drag varies strongly with velocity reflecting the re-configuration of the drag elements due to bending, behavior that can be modeled with some accuracy. In the final case, I will show velocity measurements taken over the span of several years during which time the condition of the kelp forest varied between non-existent and dense. During this time rms depth-averaged velocities varied by a factor of 3, showing the importance of kelp-dependent drag to flow. However, this last case seems substantially more complicated in that drag on flow through a kelp forest is strongly influenced by surface waves, has multiple drag sources, and involves substantial inhomogeneity in the distribution of the kelp plants themselves. Nonetheless, I will present a simplified approach to inferring drag through kelp.
Music therapy and psychological-clinical impact in surgery: a systematic review
Authors: Caponnetto Pasquale , LaMattina Gaia , Quattropani Maria C
Published: October 2022

Background

Music therapy is a discipline that makes use of music, active or passive, to produce beneficial effects on the psyche of subjects.

The field of use of music therapy has recently been broadened with the introduction of music therapy interventions to treat various problems, such as anxiety and stress, arising from pre- and post-operative psychophysical conditions.

This review aims to examine the use of music therapy and its outcomes in the context of surgery in recent years.

Methods

The main procedure was to search for studies on various scientific platforms such as PubMed, Medline, PsycINFO and CINAHL.Many studies pertaining to the topic in question were examined and from the variety of articles available, thirty-four were selected that fully reflected the focus of this review.

Conclusions

The use of music therapy is still little exploited in hospital conditions such as the one reported in this review, but despite its reduced use compared to other treatments, it has proved to be an effective technique for reducing anxiety and stress prior to surgery and for improving psychophysical conditions following surgery. Above all, the absence of side effects is emphasised since it is a nonpharmacological treatment.

Further research is needed for additional confirmation of the effectiveness of music therapy mainly because this method is still being explored worldwide.

Nordic cancer registration, a review of an invaluable source and example for surveillance, research and public health for more than 70 years
Authors: Hans H. Storm
Published: October 2022

Cancer registration has been with us for decades surveilling societies for cancer incidence, trends, mortality and survival. Data are used for health care planning but even more so for research in cancer treatment, outcome and prevention – i.e. overall cancer control. With the 70th anniversary of the Cancer Registry of Norway, this paper examines the impact and role of the registry in the past and today for cancer registration and affiliated research in the Nordic countries, as well as scientific peer reviewed productivity. The Nordic collaboration in cancer-registry-based research benefits from previous and actual ongoing activities in Norway. The Cancer Registry of Norway is a prominent independent organization under Oslo University Hospital Trust for registration and registry-based cancer epidemiology, with a multidisciplinary broad-based high quality professional staff. The research portfolio includes regular cancer registration, linkage to external data e.g. occupation, biobanks and clinical data conducting analysis with clear national, Nordic and international relevance. Various threats to the ownership of cancer registries and the derived epidemiology in past, such as organizational changes and loss of independence were avoided in Norway, but the interpretation of data protection following the GDPR today causes delays or may even block the Nordic cancer registry research.

Published: October 2022

The Cancer Registry of Norway and the Norwegian Cancer Society has a long and strong history of collaboration. The Norwegian Cancer Society was instrumental both political and financial when the Cancer Registry was founded back in 1952. In the following years, the Cancer Registry had major financial contributions from the Norwegian Cancer Society.
Throughout the history, the Cancer Registry of Norway and the Norwegian Cancer Society has had a strong collaboration on important areas as cancer research, cancer screening, prevention, and international work. The collaboration has been based on a common desire to reduce the number of cancer patients and to secure the best possible treatment for people affected by cancer.
The Norwegian Cancer Society is proud of the high standard the Cancer Registry of Norway has achieved through history, and we are looking forward to continuing our strong collaboration in the years to come.
A nationwide, prospective collection of patient reported outcomes in the Cancer Registry of Norway
Authors: Gjelsvik Ylva Maria , Johannesen Tom Børge , Ursin Giske , Myklebust Tor Åge
Published: October 2022

Background: The Cancer Registry of Norway (CRN) has collected data on all Norwegian cancer patients from health providers since 1952. To assess cancer patients’ self-reported late effects and health related quality of life(HRQoL) after treatment, the CRN started collecting data on Patient Reported Outcomes (PROs) in 2020.
Objectives: To present the infrastructure for the CRN’s national health survey collection of PROs and describe some experiences of the first two years of data collection. Methods: In 2021, the CRN invited patients newly diagnosed with prostate cancer, breast cancer, colorectal cancer, or malignant melanoma to participate in the three-year digital health survey “Population survey on health and quality of life”. Patients were invited at least 21 days after diagnosis and within 150 days of the diagnosis. A control group consisting of individuals with no history of the cancer in question was randomly drawn from the National Population Register. Descriptive statistics regarding invitations and participation are presented.
Results: A total of 15 641 patients and 15 187 individuals in the control group were identified as eligible for participation in 2021. A total of 12 297 (82%) of the patients and 11 534 (76%) of the controls used one or more of the digital solutions the CRN used to distribute the surveys and received an invitation to the survey. Overall, 6 091 (47%) of the patients and 3 718 (32%) of the controls participated, with variation across the cancer types.
Discussion: Self-reported late effects and HRQoL after contemporary cancer treatments can be studied among participants in these nationwide longitudinal surveys which continuously include newly diagnosed patients. The response rates at baseline are still somewhat low and vary between 41% and 51% among the cancer patients. Selection bias may be a challenge, as half of (or less) than the individuals invited in 2021, chose to participate.
Conclusions: The infrastructure for a national, prospective survey collection of PROs is in place and in use. The CRN plans to analyse the representativeness and validity of the PROs data. The goals are to include PROs in surveys covering all the clinical registries at the CRN, and that the PROs collected by the CRN can be used in research and quality improvement of the health services offered to cancer patients.

Training of copyright and related rights in sub-saharan Africa
Authors: Koskinen-Olsson Tarja
Published: October 2022

Training of intellectual property rights has been close to the heart of Professor Marianne Levin and she has been a Master Trainer, welcoming participants from all corners of the world. This is why I have chosen the topic of training for my article, congratulating her on her anniversary. Understanding how international copyright law and realities on the ground affect the functioning of the copyright market in a given country or region, offers a possibility to review and evaluate developments. A well-functioning copyright market consists of three elements: legislation, enforcement and management of copyright and related rights. This article concentrates on management of rights, but deals also with some legislative and enforcement issues. Management of rights takes place either individually by the respective rightsholder or by collective management organizations (CMOs). The latter is a feasible solution when individual exercise of rights is either impossible or impracticable.
The moral significance of intellectual property regulation
Authors: Hansson Mats
Published: October 2022

Fundamental ethical principles provide guidance for the protection and wider use of intellectual achievements. As regarding established rules for claims of authorship in scientific publications, use of intellectual property is not a matter of providing an open unregulated access but to honor the intellectual achievements while providing an avenue to wide application for promotion of innovation to the benefit of society. This is done through a balancing of different interests. In this article I examine some of the basic principles for this balancing task. A special concern in the discussion about intellectual property regulation has been the need to fit new scientific and technical innovations within the changing moral landscapes of different countries. Innovations must not offend what is considered "public order". I put this claim into perspective by demonstrating that this value laden concept needs to be adjusted in accordance to changing moral landscapes that often follow when new innovations become part of main stream technology and provide significant benefits.

Published: October 2022

A singleton live-born baby who weighs less than 2500 gram at birth is considered to have a low birth weight. In this research we aimed to determine whether or not there is an association between hypertension induced by pregnancy and low birth weight. We conducted a retrospective case-control study in the 1st Clinic of the Samarkand State Medical University. Pregnancy-induced hypertension was defined as blood pressure of >140/90 mm Hg. all analyses were carried out using R-studio version 3.6.2. A total of 300 participants were interviewed, of whom 150 were cases and 150 were controls. The majority of responders were between the ages of 21 and 32 (79.3%). The mean age of controls was greater (25.2±6.1 years) than that of cases (24.1 ±5.3 years). Women who gave birth to newborn with a low birth weight were 4.10 times more likely to have experienced pregnancy-induced hypertension (adj. OR = 4.10; 95% CI = 1.94-8.66, p<0.001). Women with previous history low birth weight newborn were more likely to deliver neonate with low birth weight (adj. OR = 2.40; 95% CI = 1.13-5.11, p<0.001).

Published: October 2022

This paper deals with intended to determine the decay resistance of mango (Mangifera indica) and raintree (Albizia saman) wood in fungal and field test. In fungal test, a white rot fungus (Schizophyllum commune) was used in laboratory. The average weight loss of Mangifera indica and Albizia saman wood blocks inoculated with a white rot fungus (Schizophyllum commune) for 16 weeks were 35.28% and 23.80% respectively. In field test the average weight loss were 42.36% and 28.54% respectively for M. indica and A. saman wood. In both test, degradation was higher in M. indica wood compared to A. saman wood. Thus, natural durability of A. saman wood is higher than that of M. indica wood. It is evident that M. indica wood under perishable class and A. saman wood falls under non-durable class according to natural durability classification.

Changes in the quality of Catla (Catla catla) stored immediately (0 h) in ice, after six (6) hours in ice and at ambient temperature soon after catch was investigated. The samples were examined by sensory (organoleptic and rigor mortis progress) and biochemical parameters (total volatile base nitrogen, trimethylamine nitrogen and pH). The rigor mortis proceeded faster in fish stored at ambient temperature (28°C-30°C) than those stored in ice (0°C). The duration of full rigor stage and total rigor period were 8h and 13h for fish stored in ambient temperature and 77h and 127h for fish stored in ice (both immediate and delayed icing) respectively. Organoleptically, the acceptability of fish varied between 16-20 days in both the iced storage conditions and 12-13.5h at ambient temperature. The fishes were organoleptically just acceptable on the 16th day of storage and just unacceptable on the 20th day. The values of total volatile base nitrogen (TVB-­N), trimethylamine nitrogen (TMA-N) and pH were 18.9 mg% (0h), 16.74 mg% (6 h), 5.40 mg% (0h), 4.86 mg% (6h) and 6.93 (0h), 6.65 (6h) respectively at the time of rejection for fish stored in ice. Those values for fish stored at ambient temperature were 28.44 mg%, 6.22 mg% and 7.18 respectively at the time of rejection.

Published: October 2022

Seeds of oryza sativa were cultivated in the seedlings and the effects of urea on the changes of pH in the soil and growth of paddy were observed.  Urea (80 kg/ha) was applied to one of the seedlings after 20 days of germination and the soil pH and length of paddy were determined from 25 days of urea application.  Soil pH was gradually decreased with increasing paddy grown in the control seedling.  However, no changes of pH were found in the urea treated seedling up to 20 days of germination and were similar to the control paddy.  The pH of soil compared to the control falls gradually with increasing paddy growth.  We also examined the effect of urea on paddy length and compared to the control paddy.  Paddy length was gradually increasing in both the control and urea treated seedlings from the germination.  However, higher length was found in the urea treated seedling.  Up to 20 days of germination of paddy, no differences of paddy length in the two seedlings were observed.  These findings suggest that urea is the potent compound inducing growth of paddy and pH measurements indicate the period where optimum uptake of urea is happened.

Published: October 2022

Oral health and nutrition problems in children cannot be separated. Both share the same risk factors. The high prevalence of malnutrition and Early childhood caries (ECC) in developing countries, especially in Indonesia, still needs attention. This study aims to analyze the relationship between ECC and the nutritional status of children aged five years in Indonesia based on the 2018 Riskesdas data. The study used a cross-sectional study using secondary data from Riskesdas 2018. A sample of 701 children aged five years was subjected to clinical examinations and questionnaires. ECC as the independent variable and other risk factors; self-reported oral health, gender, mother's education level, father's employment status, family economic status, children's dietary practices, and utilization of health facilities were analyzed against nutritional status based on weight/height categories converted by Z-score. Results showed that the chi-square test showed a significant correlation between ECC, maternal education level, family economic status and dietary practices at risk of children on nutritional status (p-value <0.05). Multinomial logistic regression test proved a significant correlation between ECC and wasting (OR = 1.352, 95% CI: 0.989 – 2.589). ECC is not correlated with obesity. The conclusion is ECC can cause wasting in children. Meanwhile, several risk factors for nutritional problems and dental caries were similar.

Ceramics is a dental material used often because of its relatively good strength and aesthetic properties. Ceramics such as zirconia, alumina, and silica have different characteristics and have been synthesized using a bottom-up method separately. Recently, many studies have used chitosan solution to help synthesize nanometer-sized ceramic materials processed using the bottom-up method. This study aims to produce ZrO2-A12O3-SiO2 nanoparticle ceramics, which were synthesized simultaneously using the bottom-up method, and to see the effect of volume concentration of chitosan solution on the resulting ZrO2-A12O3-SiO2 ceramic particles. The composition ratio of ZrO2:Al2O3:SiO2 used is 3:1:1 with a concentration of 0.05M and a total volume of 500ml. The chitosan solution was added with a volume percentage of 0%, 5%, 10%, 15%, and 20%, respectively, and was named samples A, B, C, D, and E. The XRD (X-Ray Diffraction) and SEM (Scanning Electron Microscopy) characterization of the five samples showed nano-sized particles, which were 87 nm, 85 nm, 81 nm, 76 ran, and 76 nm. SEM characterization results show that sample A's particle distribution is not very visible; the particle distribution is only seen in samples B, C, D, and E, while the best particle distribution is seen in sample C. This study concludes that the optimal volume concentration of adding chitosan solution to produce nano-sized ZrO2-A12O3-SiO2 ceramics with good particle distribution is 10% by volume percentage.

The pH value and salivary flow rate are important factors in maintaining the balance of the oral cavity and affect the health of the teeth and mouth. When we chew foods high in water, fibre, and vitamin C, such as grapes (Vitis vinifera) and strawberries (Fragaria x ananassa), the value of these two elements can change due to stimulation. This study aims to evaluate pH levels and salivary flow rate fluctuation before and after chewing grapes in contrast to strawberries. The research method was a quasi-experimental study; forty-two research participants from Faculty of Dentistry, Universitas Jenderal Achmad Yani students. They were divided into two groups: grape and strawberries. The experiment was divided into two parts: before and after chewing the fruit. The salivary flow rate was assessed through visual screening, and salivary pH was measured using a pH meter. Data were analyzed by t-test (p<0.05). The result shows that the mean pH value and salivary flow rate increased after chewing grapes and strawberries. Compared with before chewing fruit, this increase was statistically different (p=0.000) in the two groups. Meanwhile, when the mean difference was insignificant. Chewing fruit that contains water, fibre, vitamin C, and a sour taste can increase salivary secretion, which follows the buffer system to increase salivary pH.

Orthodontic treatment with removable orthodontic appliances requires the patient's commitment to use the appliance in the mouth at a certain time. It can lead to specific changes in the mouth, such as a decrease in the level of acidity or pH of the mouth, which may be associated with increased biofilm accumulation. The acidity level of saliva in the mouth is an important factor in several oral problems, such as dental caries and periodontal disease. The use of mouthwash is still one of the simple ways that are widely used to overcome these problems. Among the many types of mouthwash on the market, sorbitol mouthwash is an option that can be used to prevent changes in the acidity level of saliva from reaching a critical value of < 5.5 and endangering the oral health of orthodontic patients. This study aims to determine the change in salivary pH of patients in orthodontic treatment with removable appliances before and after immersion with sorbitol mouthwash. The research method was an experimental laboratory study conducted with pre-test and post-test designs involving 33 samples divided into three groups, each consisting of 11 samples. Immersion time is divided into three categories, namely 15, 30, and 60 seconds. A pH indicator measures the level of saliva acidity. The results show that there are different changes in pH in each period of immersion. The conclusion was that immersion in sorbitol mouthwash resulted in changes in the pH level of saliva in removable orthodontic appliances, and the sufficient soaking time is 15 seconds.

Lung carcinoma is cancer that develops from the abnormal proliferation of lung epithelial cells. Lung carcinoma has two forms: Non-Small Cell Lung Carcinoma (NSCLC) and Small Cell Lung Carcinoma (SCLC). NSCLC makes up 85% of lung carcinomas cases. EGFR overexpression is often seen in NSCLC. This research aims to discuss and provide information about the patient's characteristics, smoking status, functional status, clinical stage, histopathological diagnosis, and EGFR test of NSCLC. This research is a literature study that collects, manages, uses and reviews research data from scientific journals, previous research manuscripts, and textbooks. The literature review results were that most patients with NSCLC were found in the 55–65 age group. NSCLC can happen to both genders. NSCLC was found in smokers and non-smokers. The patient's functional status was mostly "very dependent". The clinical stage of NSCLC patients is often found in stages III and IV. The most common histopathological diagnosis of NSCLC was adenocarcinoma. EGFR results can be positive or negative; most occur in the adenocarcinoma subtype. EGFR overexpression in NSCLC occurs due to somatic mutations in the tyrosine kinase domain, causing continuous signal transduction and phosphorylation.

Aiming at the coordination and scheduling problem between Automated Straddle Carrier (Automated Straddle Carrier) and Quay Crane (QC) in automated container terminals, consider that the quay crane cannot cross the straddle carrier, and the straddle carrier and the quay crane cannot be in adjacent lanes at the same time. A mixed-integer optimization model with the objective function of minimizing the final completion time of the quay crane is established under the constraints of different operating speeds and different speeds of straddle carriers in different states. A genetic algorithm based on reinforcement learning is designed, and the initial population is generated by the Q-learning algorithm, and the genetic algorithm (GA) is iterated to increase the diversity of the initial population. Finally, taking 5 groups of experiments as examples, the model is compared and solved by GAMS solver, genetic algorithm and genetic algorithm based on reinforcement learning. The results of an example show that the genetic algorithm based on reinforcement learning can solve the model and make the value of the objective function smaller, thus verifying the feasibility of the modified algorithm.
