Grasshoppers are insects that are pests for agriculture. In recent years, humans have begun to realize the broader economic value of insects, which are not only used as animal feed but also as sustainable biopolymers, such as chitin and chitosan. Grasshoppers' body organs contain chitin, including the digestive tract (intestine), trachea system, and exoskeleton (outer skeleton). Currently, the chitin extraction process using the green method with Deep Eutectic Solvent (DES) is more popular because it reduces the use of dangerous chemicals, reduces waste, and is overall more environmentally friendly than using chemical and biological methods. In the chitin extraction process, process parameters, such as reaction time, temperature, and particle size of the raw material, are adjusted to obtain the desired properties of chitin. This research aims to determine the effect of particle size and temperature on chitin yield and degree of acetylation (DA). The research results show that the yield values ​​and DA values ​​produced in this research are not by similar references which have described the characteristics of chitin. However, there is one sample showing that the most optimal DA value is the BSC 7 150 mesh 90°C sample, at wavelengths of 1560 cm-1 and 2875 cm-1, producing a DA value of 55.79514% and DD 44.20485933%. The best yield value was BSC 2 110°C 50 mesh, with a value of 22.1%.

The Turkish Validation of the Mentalization Questionnaire and Mediation Its Dimensions on the Relationship Between Attachment Insecurity and Borderline Features in Young Adults
Authors: Kaynar-Yaman Gülşen
Published: September 2024

This study aimed to test the psychometric properties of the Turkish
version of the Mentalization Questionnaire (MZQ) and the mediating roles
of dimensions of the MZQ in the relationship between attachment
insecurity and borderline personality disorder (BPD) features. Four
hundred eighty-four young adults (82.2% women, 17.8% men) aged between
18 and 37 completed the Turkish translation of the MZQ, the Experiences
in Close Relationships Scale-Revised (ECR-R), the Reflective Functioning
Questionnaire (RFQ), the Borderline Personality Inventory (PBI), and the
Brief Symptom Inventory (BSI). Exploratory (EFA) and confirmatory factor
analyses (CFA) were conducted after randomly splitting the dataset. EFA
indicated a three-factor solution, and CFA supported this three-factor
model, which consisted of emotional self-reflection, pre-mentalizing
modes, and affect regulation. Construct validity was further established
by significant correlations of the MZQ with reflective functioning and
indicators of maladaptive psychological functioning. Emotional
self-reflection and regulation of affect both mediated the positive
relationship between attachment insecurity and BPD features.
Pre-mentalizing modes moderated the relationship between attachment
anxiety and BPD. The Turkish version of the MZQ can be an applicable and
reliable tool for assessing mentalizing deficits not evaluated by prior
tools.
Mental health and medicine use for headache: National representative study of adolescents in Denmark
Authors: Holstein Bjørn Evald , Toftager Mette , Román Julie Ellegaard Ibáñez , Madsen Katrine Rich
Published: September 2024

Purpose: To present the prevalence of medicine use for headache
in a nationally representative sample of adolescents in Denmark, and to
examine the association between poor mental health, frequent headache,
and medicine use for headache. Our hypothesis was that poor mental
health increases the risk of headache which triggers medicine use for
headache. Methods: The Danish arm of the 2022 Health Behaviour
in School-aged Children (HBSC) study included 5,767 11-, 13- and
15-year-old students with self-reported data about headache frequency,
medicine use for headache, and five indicators of mental health: Life
satisfaction, emotional symptoms, loneliness, self-efficacy, and
self-esteem. We used multivariate logistic regression analyses to
examine whether the indicators of mental health were associated with
medicine use for headache and whether inclusion of headache frequency in
the statistical models changed the associations. Results: The
prevalence of headache at least weekly was 32.7%. In the last month,
42.7% had used medicine for headache. Students with poor mental health
had significantly higher rates of headache and significantly higher
rates of medicine use for headache. For example, the OR (95% CI) for
medicine use for headache was 2.27 (1.90-2.72) among students with low
life satisfaction. When headache frequency was included in the
statistical models, the associations between poor mental health and
medicine use for headache attenuated and became insignificant. For
example, the OR for medicine use for headache attenuated to 1.18
(0.96-1.41) among students with low life satisfaction.
Conclusions: Poor mental health was associated with medicine
use for headache. Poor mental health was also associated with frequent
headache. The analyses suggest that frequent headache may be the
explanatory factor behind the association between poor mental health and
medicine use for headache. There is a need for promotion of rational
medicine use among adolescents and mental health promotion may
contribute to this effort.
A positivity-preserving, energy stable BDF2 scheme with variable time steps for the liquid thin film coarsening model
Authors: Guo Yunzhuo , Dong Lixiu , Zhang Juan
Published: September 2024

We present and analyze a second order numerical scheme with variable
time steps for a liquid thin film coarsening model, which is a
Cahn-Hilliard-type equation with a singular Leonard-Jones energy
potential. The fully discrete scheme is mainly based on the Backward
differentiation formula (BDF) method in time derivation combined with
the finite difference method in spacial discretization. A second order
viscous regularization term is added at the discrete level to guarantee
the energy dissipation property under the condition that r ≤ r max . The
uniquely solvable and positivity-preserving properties of the numerical
solution are established at a theoretical level. In addition, based on
the strict separation property of the numerical solution obtained by
using the technique of combining the rough and refined error estimates,
the optimal rate convergence analysis in ℓ ∞ ( 0 , T ; H h − 1 ) norm is
established when τ≤ Ch by using the technique of the
discrete orthogonal convolution(DOC) kernels. Finally, several numerical
experiments are carried out to validate the theoretical results.

Published: September 2024

Offspring and kin care are common in nature, while non-kin societies are
unusual due to their susceptibility to cheaters. Here, we investigated
the kinship of mast-building amphipods, Dyopedos bispinis
(Gurjanova, 1930). Our goal was to determine if all mast inhabitants are
descendants of a single founder female or if they represent a more
complex social structure. We sequenced and assembled the complete
mitochondrial genome of D. bispinis along with 59 partial genomes
from four masts. One of the studied masts contained several adult
females with embryos, all of which had identical partial mitochondrial
genome sequences. This shows that masts can be inhabited by individuals
from different generations. Mitochondrial genome sequences of ten
mother-embryo pairs confirm maternal mtDNA inheritance in D.
bispinis. However, another mast contained several groups of female
individuals exhibiting pronounced (~0.7 substitutions per
1000 b.p.) distance between the groups. The genetic distance between
groups from the same mast was not less than the genetic distance from
specimens of other masts. This suggests collective usage of the mast by
non-related families. Given that adult female D. bispinis
individuals invest resources into mast maintenance, this case implies
non-kin cooperation among amphipods. Overall, our study provides an
insight into the family structures of mast-inhabiting amphipods and
presents a new model for studying the cooperation of non-related
individuals.

Published: September 2024

Mild psoriasis may be burdensome; if symptoms are inadequately controlled, switching therapy may be warranted. In the Phase 3 NAVIGATE trial, patients with moderate-to-severe plaque psoriasis received ustekinumab for 16 weeks. Patients with inadequate response (Investigator’s Global Assessment [IGA] ≥ 2) were randomized to switch to guselkumab or continue ustekinumab. This post-hoc analysis evaluated the patient subgroup with residual mild psoriasis (IGA = 2) after initial ustekinumab therapy. Outcomes assessed included the Psoriasis Area and Severity Index (PASI), Dermatology Life Quality Index (DLQI), and Psoriasis Symptoms and Signs Diary (PSSD). Initially, 871 patients received ustekinumab. At Week 16, 161 randomized patients had residual mild psoriasis (IGA = 2). Among guselkumab- vs ustekinumab-treated patients at Week 28, 59.0% vs 27.7% achieved PASI 90, and 50.0% vs 21.0% achieved DLQI 0/1. Mean changes from baseline in PSSD score were –44 vs –28 and –50 vs –32, respectively, with thresholds of –40 considered clinically meaningful. Mean changes in PSSD itch score were –4.6 vs –2.9, with reductions ≥ 4.0 considered clinically meaningful. Treatment differences were maintained/increased through Week 52. Among patients with residual mild psoriasis after 16 weeks of ustekinumab, those switching to guselkumab had greater improvements in skin clearance, health-related quality of life, and patient-reported symptoms and signs than those continuing ustekinumab.

Pain Neuroscience Education for Physical Therapy Assistant Students: An Exploratory Study
Authors: CL Kiefer , A Louw , JL Weil , K Zimney
Published: September 2024

Background: The chronic pain epidemic requires all healthcare providers to develop an updated, uniform understanding of modern pain science. Objective: To determine if a 2-hour pain neuroscience education lecture to physical therapy assistant (PTA) students yields any positive shifts in pain knowledge and attitudes and beliefs regarding chronic pain. Design: Pre and post-education survey Methods: A convenience sample of PTA students at two schools volunteered for the study. Students received a 2-hour pain neuroscience lecture, either in-person or live, online. Prior to and immediately following the presentation, knowledge of pain (revised neurophysiology of pain questionnaire) and attitudes and beliefs regarding pain (health care provider’s pain and impairment relationship scale and pain attitudes and beliefs scale) were administered. Results: Thirty-five students completed the pre- and post-education surveys. No significant changes were found in pain knowledge, (p = 0.241). Interestingly, nearly all (94.3%) of the students were exposed to pain neuroscience education prior to the lecture in their PTA program, with high pre-education pain knowledge scores then previous studies investigating student pain knowledge Significant changes were found for the health care provider’s pain and impairment relationship scale (p = 0.01), and pain attitudes and beliefs scale for biomedical beliefs (p = 0.014), but not the biopsychosocial scale (p = 0.142). Conclusion: PTA students in this study had a lot of previous exposure to pain education, leading to high pain knowledge levels. A lecture on pain neuroscience can shift physical therapy assistant students away from a pure biomedical view of chronic pain and increase their empathy and compassion towards patients with chronic pain, but it is not able to foster a stronger biopsychosocial view of chronic pain.

APPLICATION OF THE PRINCIPLE OF NOTARY ACCURACY AS AN EFFORT TO AVOID THE PRACTICE OF MAKING NOMINEE AGREEMENTS RELATED TO THE TRANSFER OF LAND OWNERSHIP TO FOREIGN CITIZENS
Authors: Tiara Elfira Dela , Abubakar Lastuti , Baraba Badar
Published: September 2024

This research aims to examine the implementation of the principle of notary accuracy as an effort to avoid the practice of making nominee agreements regarding the transfer of land ownership rights to foreign citizens along with the legal consequences for notaries who ignore the principle of equality with those making deeds based on these agreements.The research method used is normative juridical by examining library materials or secondary data, including legal principles, legal systematics, research on levels of vertical and horizontal synchronization, and legal comparisons. This research uses an applicable legislative approach linked to legal theories and practices relating to legal issues with analytical descriptive research specifications and qualitative juridical data analysis methods.Based on the results of the research, it can be concluded that the refusal to make a deed based on a nominee agreement regarding the transfer of ownership rights to land to a foreign citizen is part of the implementation of the principle of notarial accuracy considering that the deed violates the objective requirements in the form of a halal cause in the terms of the validity of the agreement in Article 1320 of the Civil Code and results in a deed declared null and void by law. Cancellation of an act of nominee agreement provides a legal basis for imposing civil sanctions on the Notary, which may include payment of fees, compensation and interest. By considering the impact, Notaries should carry out their duties carefully, professionally, prioritizing integrity and good morals.
Model of limited resource distribution when ensuring the safe operation of the vessel
Authors: Poznyakov Sergey Ivanovich , Suslov Aleksandr Nikolaevich , Penkovskaya Kseniya Vyacheslavovna
Published: September 2024

A model for the safe operation of a vessel with a limited resource is considered, depending on the values of efficiency parameters proposed by ship services and their application. When projecting the conditions presented by this model, it is possible to identify a number of strategies that could be optimal according to the principle of maximum guaranteed results for ship services. Depending on the number of ship services and the initial awareness of the ship administration, the model may be optimal for any safety management systems of fishing or transport companies in general. When maintaining a running watch, ship specialists are forced to assess the state of the navigation (or fishing situation) under the influence of a wide range of ambiguous, dual factors. To maintain a safe state of the situation, ship services implement resource requests. The size of a resource always has a finite limit. When allocating resources, the captain must take into account the “needs” of all ship services and provide them with resources in such a way that the safety of the navigation (or fishing situation) is maintained at the required level. To do this, the maximum level of the amount of resource intended for a particular ship service must be determined. It is also important to consider that at any given time a certain reserve must be maintained for each resource. Within the framework of the model of safe operation of the vessel, the scheme for implementing a request for a resource, as well as the process of resource distribution, is considered. It is proposed to build a model of relationships between ship services in the process of distributing a limited resource. An assessment of the effectiveness of the game model of resource distribution is proposed through the assignment of the relative error value. The possibility of the emergence of a situation of balance of interests in the system of relationships between the heads of ship services is analyzed. The solution to the problem of safe operation of the vessel is realized through the analysis of indicators of resource costs and the efficiency of its use.
On electromagnetic and mechanical interactions in asynchronous machines
Authors: Kagakov Yuri Nikolaevich , Zimin Vyacheslav Valer'evich
Published: September 2024

A detailed analysis of electric power and electromechanical interactions in asynchronous machines is carried out from the standpoint of the fundamental laws of electrophysics, analytical mechanics and theoretical electrical engineering. A structural and logical scheme (roadmap) of the movement of electromagnetic energy from the engine power source to the rotation of the shaft and the drive mechanism rigidly connected to it is proposed. Each stage of the energy movement is accompanied by an explanation of the causes of the movement with references to the laws and postulates of electrophysics and electromechanics that form these stages. The formation of the fundamental law of motion of mechanical energy is shown, accompanied by potential (external to the engine), kinetic (internal mechanical) and energy associated with thermal losses of the rotating system “engine – drive mechanism”. At the same time, the physical foundations of the formation of the corresponding torque and braking moments are shown. The mistakes made in some textbooks in the formation of mathematical models of asynchronous motors are determined. The physical foundations of the formation of external (potential) energy and the power consumed by the engine from an external source are investigated. It is confirmed that the main reason for the rotation of the motor rotor is the Ampere force formed by the corresponding law of electrodynamics. Analytical dependences are given that allow calculating both the magnitude of the force and the direction of rotation of the engine shaft. According to the magnitude of the force acting on the rotor, the corresponding energy and braking torque are easily determined. The conditions for the formation of the nominal rotation speed of the rotor are considered. The process of forming the kinetic energy of the rotating inertial mass of the “motor – drive mechanism” system is shown. Graphs of changes in all types of energy within the framework of the law of conservation and transformation of energy are given, which allow us to visually analyze the processes in the machine. Conclusions are drawn about a significant expansion of capabilities in calculating the operating modes of the machine.

Authors: Indah Fajarwati  , Jayadi Ahkam
Published: September 2024

Drug crime is a serious threat with far-reaching repercussions, mainly due to its transnational nature. Indonesia, including one of the countries famous for the circulation of narcotics, is not only a target but also a transit area for perpetrators of this crime before reaching the final destination. Narcotic abuse is not a legitimate and often uncontrollable behavior, but rather is carried out in order to obtain disordered psychotropic effects. As a result, it not only damages physical and mental health, but also has serious social repercussions. Therefore, the handling of drug crime is an important priority in order to maintain the safety and welfare of the community.

Disabilities are defined as people who show functional difficulties along with the obstacles present from the social environment so as to limit their participation in society. This research aims to provide insight for policy makers, practitioners, and organizations that care about the rights of workers with disabilities in developing and improving existing regulations and policies. This study uses a comparative legal research method that compares existing regulations in Germany, Canada, Australia, Japan, and the US with existing regulations in Indonesia through a statutory law research and a conseptual approach. The novelty in this writing is to conduct a comparative study of the rights of workers with disabilities from 4 continents, especially with 6 different countries to create ideal regulatory and policy concepts that can be implemented in Indonesia. However, Indonesia itself has created a Disability Vocational Training Center (PPVD) which aims to empower disabled workers to welcome an inclusive Indonesia.
Legal Protections for Limited Liability Company Shareholders with Mental Health Disorders
Authors: Fakhri M Rivaldo
Published: September 2024

Minority shareholders, including those suffering from mental illness, frequently encounter numerous obstacles in securing adequate legal protection. The study employs a normative juridical method with a statutory approach to address its objectives. The results showed that the shareholders can file direct lawsuits against the company or derivative lawsuits on behalf of the company if the directors or management engage in unlawful activities that infringe on their rights, as outlined in the corporation law. They can also initiate lawsuits against the company in cases of loss or psychological harm. In situations where the company suffers a loss, the right to sue belongs to the company itself, not to the minority shareholders, reinforcing a bias towards the directors over minority shareholders, including those with mental disorders, since the directors are authorized to represent the company in legal matters.

Authors: Muhairina Nurul , Zulkarnain
Published: September 2024

Palm oil theft is a common crime in Indonesia, regulated by positive law. However, in the case of theft crimes in Medan Labuhan District, the use of restorative justice and Islamic criminal law is used to resolve these cases. This study aims to analyze the role of restorative justice in handling oil palm theft cases in Medan Labuhan sub-district from the perspective of Islamic criminal law. Restorative justice focuses on restoring relationships between victims and the community through dialogue and mutual attestation, compared to a retributive approach that focuses on providing punishment. This qualitative research, using empirical juridical approaches and field research techniques, concludes that restorative justice in the Islamic criminal law system can be an effective alternative in handling theft cases, especially in the community of Medan Labuhan District. This approach aligns with the principles of shura (deliberation), which prioritize peaceful settlement and the restoration of social relations.

The COVID-19 pandemic prompted global crises and enforced strict measures like the Movement Control Order (MCO) in Malaysia, significantly impacting societal norms, particularly affecting secondary school students. The current study employs a qualitative methodology to determine how COVID-19 affects the life stress experienced by secondary school students. Secondary school students were recruited in Sabah, Malaysia, from April to August 2022, after Malaysia entered the endemic phase on 1 April 2022. As part of a larger survey, students were asked to respond to an open-ended question about life stressors they face as a result of the pandemic COVID-19 or during home-based teaching and learning (PdPR). A total of 1069 secondary school students from various backgrounds were included in the study. However, only 714 students responded to the open-ended question. The pattern of meaning across the texts was determined using Birks and Mills’s method of multilevel coding. The students’ perspectives on life stressors were classified into five broad categories: restriction stress, emotional stress, online study stress, family-related stress, and others-related stress. Restriction stress, which refers to being confined at home, restricted movement, hampered family, friendship, and outdoor activities, and no freedom were rated as the most significant life stressors associated with the COVID-19 pandemic by students. This research provides valuable insights for policymakers, educators, and parents, emphasizing the profound effect of pandemic-induced restrictions on student life and the essential role of targeted interventions in fostering resilience among students.

E-commerce is increasingly developing as a platform large and small companies use to carry out online transactions with consumers. However, the development of e-commerce is also fraught with new environmental problems. Various problems occur, such as data leaks and fraud in buying and selling transactions. This research aims to deepen the study of the e-commerce environment from the perspective of local policymakers, and this research completes a study on the analysis of e-commerce problems and solutions from the perspective of policy actors. The development of e-commerce still has an unsafe environment; the potential for fraud and data leakage is still significant, and a government response is needed, such as creating new regulations or revising existing regulations. This research uses qualitative analysis with a content analysis approach and national online news media as research data and information sources. Nvivo 12 Plus software was used to identify problems and solutions offered by actors in their narratives in the media. The results of this research show that data leaks and e-commerce have the potential to threaten the country’s resilience, conventional businesses are threatened with closure, and policymakers are shifting responsibility for overcoming e-commerce problems. Current regulations still need to be made appropriately to overcome e-commerce problems.
