Published: May 2023

Solar energy is a non-vanishing renewable source of energy that is eco-friendly. However, the solar energy adoption rate in Malaysia remains low due to the low readiness level among the Malaysian. This phenomenon should be emphasized where solutions need to be figured out to encourage the adoption of solar energy in buildings. Thus, this research was conducted to explore the readiness and challenges of the Malaysians in adopting solar energy. A mixed research method was adopted where a totalof 200 sets of online questionnaire surveys were distributed to the public, and a semi-structured interview was carried out to obtain the opinions from the expert in the industry. Based on the findings of the questionnaires, the top 3 challenges in solar energy adoption are (1) high setting up cost of solar panels, (2) limited public awareness of solar energy and (3) efficiency of the solar panel depends on the weather. Next, the qualitative study found that 48.9% of 139 respondents were willing to adopt solar energy in the future. The findings show that that breaking down the barriers of high investment cost and long return investment would further enhance the solar energy adoption rates at the residential scale. Since this study had explored the challenges and solution to these barriers, the outcomes of this study can be used by the policy maker as the fundamental to encourage the adoption of solar energy in the existing buildings where the current adoption rate is low.

Labour efficiency is crucial for a construction firm’s long-term viability. According to recent studies, modernising organisational and administrative procedures is essential to improving labour efficiency in many developing countries, including Sri Lanka. The perspectives of construction engineers play a key role in strengthening organisational policies and management practices in the construction industry. As a result, based on the viewpoint of construction engineers, this study aims to identify the critical organisational elements that highly influence labour efficiency in Sri Lankan road construction projects. The elements/factors were qualitatively discovered after a thorough literature review. Then, a questionnaire survey was conducted among construction engineers employed by 31 Sri Lankan road construction contractors. The Relative Importance Index (RII) method was used to quantify each element’s level of influence on labour efficiency. Based on RII values, 33 organisational elements were determined as critical, where lack of communication and cooperation between the parties, delay in salary payment and lack of labour training facilities were determined as the top three ranking elements in the list. The validity and reliability of the results were confirmed by additional statistical tests. Using problem-based communication strategies, industry consultations were conducted among construction experts to determine the necessary future measures from relevant authorities based on the identified critical elements. These consultation outcomes suggest that the organisational policies of construction enterprises currently in place addressing financial procedures, communication strategies, resource management, performance management and training development practices must be improved in light of the new normal conditions facing the industry. The study findings might help to close the gap between management/organisational policies and workforce practices. Despite the fact that the study findings are limited to the Sri Lankan road construction industry, some of them could be used to address comparable issues in other developing nations.

This paper describes the work of a study carried out to investigate the mechanical strengths and carbon foot print of foamed concrete incorporating with local industrial wastes. Experiments were performed to obtain a minimum 28 days compressive strength of 15 MPa modified foamed concretes by using palm oil fuel ash (POFA) and fly ash (FA) as partial cement replacement and unprocessed rush husk ash (RHA) as partial fine aggregate replacement. Carbon footprint analysis was carried out by determining the CO2emission for each constituent materials in the modified foamed concrete mixes. Although incorporation of POFA in the foamed concrete containingRHA fine aggregate gained lower mechanical strengths compared to the use of FA, the minimum compressive strength is still can be attained. In terms of the sustainability, modified foamed concrete with 30% POFA or 30% FA was found an encouraging reduction of carbon foot print up to about 30% compared to the control foamed concrete. Based on eco-strength indicator, the optimum foamed concrete mix with POFA was found to be at 22.5% cement replacement level. The eco-modified foamed concrete has good potential in civil engineering construction and environmentally friendly.

Johor traditional Malay houses are typically known for its Limas roof. However, apart from the significant roof, woodcarving motifs found in Johor traditional Malay houses also possess a distinct architectural heritage that can promote the identity of a region. Many woodcarving motifs are found and should be studiedand managedto sustain the identity of a local region as part of heritage sustainable management. A study on typology of woodcarvings motifs is critically needed in order to avoid losing the authenticity of each state if not being preserved and documented. Johor traditional Malay houses are being demolished day by day before we get to know the typology of it’s woodcarving motifs. The objective of this paper is to identify the woodcarvings motifs found in Johor traditional Malay houses, reveal the typology and analyze the mostly used to be named as the identity of Johor woodcarving motif. Site visits were conducted to 60 traditional Malay houses around Johor in which the woodcarvings motifs were examined, photographed and documented. Interviews were also conducted with the house owners or occupants, and the wood carvers. The samples were analyzed,and the results were verified by experts. A total of 12typologies derived from 13 motifs were discovered, drawn, codedand named. The pumpkin motif preceded the percentage of the analysis statistics of mostly used and wasnamed as Labu Maya. The findings of this research suggest that the Labu Maya motif represents the identity of woodcarving motifs of Johor traditional Malay houses. From the analysis and discussion made, 12 typologies on Johor woodcarving motifs were revealed, named and documented. This research has shown the local authenticity, beautiful heritage that should be enhanced through managing the typology and sustaining the local identity as part of sustainable management. All these typologies are important for Johor architectural heritage, body of knowledge and also for tourism purposes.

The concept of Building Information Modelling (BIM)has attracted greater attention in the Malaysian construction industry since its introduction in 2007. Several projects in Malaysia such as Pusat Kanser Negara and Convocation Hall, UTHM have adopted this concept. One of the benefits of BIM is the projection of a 3D image of the proposed building, which allows stakeholders to get a better idea of the actual building. BIM also improves the planning and design process of the project and thus the quality of the actual building. These advantages of the BIM concept are crucial for the success of the project. Despite the implementation and benefits of BIM, there are still uncertainties about the actual performance of organisations using BIM. This is because there are no evaluation tools or models in Malaysia thatcan evaluate BIM performance of BIM. Therefore, this study aims to develop a performance model for the implementation of BIM in the Malaysian construction industry. In this study, the AHP technique was used to collect data. The AHP results have successfully assigned weights to all BIM performance metrics. The consensus value also exceeds 50%, which confirms that the experts' agreement on the weighting of the metrics is acceptable. In conclusion, the proposed and developed BIM performance model could be useful to practitioners, especially the government and CIDB, in evaluating the performance of BIM organisations in the Malaysian construction industry. These measurement results could be a basis for future improvements for BIM organisations.

Road traffic accidents are one of Malaysia's top five major causes of death and is one of the most critical public health concerns in2023. As a result, this article offers research based on data from different Malaysian government organisations andanalysing the changes in the pattern of Road Traffic Crashes (RTC) in Perak,Malaysia. From 2011 to 2018, data was analysed based on road traffic collisions and categories of casualties concerning gender, age, types of roads and vehicles, and road users. The mortality and injury rates per 100,000 people were used to calculate performance for road safety. It was found that with a 0.59% increase in Perak's population and an increase in the number of cars, there are30,669 total crashes and 491 road deaths in 2020. Furthermore, this study discovered that motorcycles were the most common vehicle involved in road traffic deaths from 2011 to 2018, which should raise concerns sincemotorbikes have become an essential mode of transportation. In Perak, most road deaths were males between the ages of 16 and 20. Finally, this study discovered that the death and injury rates per 100,000 people in Perak are 19.56 and 75.82, respectively, indicating that the fatality rate is dropping, but the injury rate increased dramatically in 2020 compared to 2019. The Perak state administration must investigate why the situation has worsen aftera decade. Somehow or rather, the state must address this issue, and it is advised that further research be conducted to identify mechanisms to enhance the current scenario to lower the number of RTCs, notably deaths, in the state.

Conducting laboratory experiments in educational institutions has been linked with the increased amount of chemical waste disposed in the environment. The excessive usage and disposal of Dichloromethane (DCM) has been attributed to financial and environmental concerns. This present study aimed to treat the DCM containing laboratory wastewater using Photoelectric Fenton(PEF) process. The PEF treatment was done at varying ultraviolet (UV) light intensity (3, 6 and 9 Watts), sacrificial anode (Al, Cu and TiO2), and oxidizing agent (OA) loading ratio (1.13, 3.76, and 6.39 w/w) under 30oC and 1 atm. Results have shown that the highest degradation (99.82%) of DCM was obtained at 9 Watts of UV light intensity, 3.76 w/w [H2O2]: [Fe2+] OA loading ratio, and with TiO2coated with IrO2 and RuO2as the anode. It was detected that higher UV light intensity favors the degradation efficiency when using the TiO2coated with IrO2and RuO2 anode. On the other hand, higher OA loading ratios proved to negatively affect the process as high concentrations of H2O2become ineffectual for the degradation of organics. Finally, analysis of variance (ANOVA) showed the positive correlation between degradation efficiency and UVA light intensity. This confirmed the applicability of the PEF process in degrading of recalcitrant pollutants in wastewater, thus showing potential for mitigating its environmental impact as an eco-friendly and cost-effective approach of wastewater treatment.

Worldwide, rapid urbanization has resulted inextensive construction of infrastructure, focus on new building projects within cities which has contributed towards drastic surge in the generation of construction and demolition (C&D) waste. Lack of proper treatment of this waste results in adverse environmental impacts in the form of air pollution, water pollution, the lack of availability of aggregates, shortage of landfill sites etc. Therefore, there is need for effectively managing C&D waste. Rules exist for sustainably managing solid waste however, major challenge is posed by the inability to effectively plan and properly manage this system while ensuring implementation of the existing rules. This research paper presents options for managing the growing C&D wastes and also recommends mechanisms to ensure that the system is financially sustainable as well. Application of approaches such as WGR (waste generation rate), LCA (lifecycle assessment) and EPR (extended producer responsibility) is suggested.

Authors: Al-Zuhairi Ala’a Hussein Alwan , Al-Fatlawi Wjdan Dhaif Sahi
Published: May 2023

In this study the simple pullout concrete cylinder specimen reinforced by a single steel bar was analyzed for bond-slip behavior. Three-dimension nonlinear finite element model using ANSYS program was employed to study the behavior of bond between concrete and plain steel reinforcement. The ANSYS model includes eight-noded isoperimetric brick element (SOLID65) to model the concrete cylinder while the steel reinforcing bar was modeled as a truss member (LINK8). Interface element (CONTAC52) was used in this analysis to model the bond between concrete and steel bar. Material nonlinearity due to cracking and/or crushing of concrete, and yielding of the steel reinforcing bar were taken into consideration during the analysis. The accuracy of this model is investigated by comparing the finite element numerical behavior with that predicted from experimental results of three pulloutspecimens. Good agreement between the finite element solution and experimental results was obtained.

Published: May 2023

This paper presents an integrated soft start-upcircuit implemented in a 0.5-μm GaN on Si technology suitable for on-chip integration in power applications. The proposed approach avoids the use of large on-chip or external capacitors to overcome the problem of voltage overshoot and inrush current at start up in switching power converters. It could be also adapted to the specific application by choosing the number of Flip Flops, or, for large start-up periods, using a counter, and setting the desired start-up signal duty cycle. Moreover, an optimized Flip Flop circuit topology has been proposed to reduce area occupation.The circuit working principle and the design challenges in GaN technology are discussed together with simulations. The circuit has been designed by considering worst-case conditions. A test buffer has been also included to drive the high external load capacitance of the readout device. Measured waveforms are reported that demonstrate the effective circuit operation and suitability for all-GaN integration.
PR12 Long Silicon Photonic Coupled-Microring Coupled-resonator Optical Waveguides: Design and Fabrication (Project Report 0642603-Y3)
Authors: Mookherjee Shayan
Published: May 2023

This NSF-funded project [0642603] is a five-year (60 months) CAREER (Faculty Early Career Development Program) unified research and education development program, with a focus on the physics and applications of nonlinear optics in the CROW (Coupled Resonator Optical Waveguide) device structure. In wavelength conversion, the optical output power at the new wavelength (i.e., the idler) depends quadratically on the propagation length (in the low power regime). It is important to realize long CROW structures which requires designing slow-light waveguides with low loss and low disorder. As studied here, the fabrication of low-loss slow-light waveguides can be challenging due to several factors, including material losses, fabrication imperfections, and scattering losses.

This report is on an NSF-funded project [0642603], which is a five-year (60 months) CAREER (Faculty Early Career Development Program) unified research and education development program, with the full title “CAREER: Chip-scale low-power nonlinear optics using coupled resonators and CROWs”. CROW is an acronym for Coupled Resonator Optical Waveguide. The focus of this project is a study of waveguiding and potential applications of the CROW structure. Its unique light-guiding and dispersion properties may make it useful for nonlinear optics using integrated semiconductor devices. This, in turn, could be beneficial for optical communications and all-optical signal processing at the milliwatt-scale power level, as is typically used in practical communication networks, and allow more intelligent optical networks. In contrast, nonlinear optics is traditionally studied in table-top or breadboard experiments using dielectric crystals or long lengths of fiber (glass) at much higher power levels.

Solving a seismic mystery with a diver’s camera: A case of shallow water T -waves in the Persian Gulf
Authors: Salaree Amir , Spica Zack , Huang Yihe
Published: May 2023

Sparse offshore coverage of seismic networks has hindered detailed studies of submarine earthquakes and their associated seismic hazard. We present results of our analysis of a diver’s recording of acoustic signals from an ML=5.6 earthquake in the Persian Gulf. We model the signals as a set of several shallow water T phases the frequency and group velocity of which are determined by bathymetry. We show that the audio track from this recording can provide reliable estimates of earthquake location and seismic moment. We also show that the reported shaking in the southern Persian Gulf, >170 km from the source of this small earthquake could result from T waves traveling through the entire width of the basin. Our results point to rudimentary and affordable underwater microphones similar to those used in the divers' cameras as tools to build efficient, low-cost networks for the study of offshore events and early warning.
Transcutaneous auricular vagus nerve stimulation modulates the processing of interoceptive prediction error signals and their role in allostatic regulation.
Authors: Ventura-Bort Carlos , Weymar Mathias
Published: May 2023

According to the predictive coding theory, the brain continuously generates predictions about upcoming environmental and internal body states. These predictions are compared with actual inputs and when they mismatch (i.e., prediction errors) the organism aims at reducing this discrepancy to guarantee a proper adaptation. These predictive principles may also apply to interoception, which encompasses the processing of hormonal, autonomic, visceral and immunological signals. In the current study, we aimed at to providing empirical evidence for the role of interoceptive prediction errors signals on allostatic adjustments, using transcutaneous auricular vagus nerve stimulation (taVNS) as a proxy to modulate the precision of interoceptive afferences. In a two-session, cross-over, within-subject design, participants performed a cardiac-related interoceptive (and control) task under taVNS or sham stimulation. We observed that taVNS, in contrast to sham stimulation, facilitated the maintenance of interoceptive accuracy levels over time, suggesting that vagus nerve stimulation increased the precision of cardiac afferent signals. In line, during the interoceptive task, taVNS compared to sham, increased heart-evoked potentials (HEP) amplitudes, a correlate of cardiac-related prediction error processing. . Further analyses revealed that the positive relation between interoceptive accuracy and HEP amplitudes during taVNS mediated the association between HEP and allostatic adjustments as measured by heart-rate variability (HRV). Validating predictive processing accounts of interoception, our results indicate that the processing of interoceptive prediction error signals modulates allostatic adjustments, as a function of interoceptive accuracy, particularly when the precision of afferent signals is promoted by non-invasive vagus nerve stimulation.
Is the timing of human warfare correlated with cyclical dopamine and serotonin levels?
Authors: Khan Tariq
Published: May 2023

A short and informal essay speculating on the impact of pollen and, thus, histamine on human serotonin levels, especially violence and warfare. The peak pollen months in spring of February, March, April, and May and the fall months of August and September are proposed as having higher levels of “impulsive anger” from the histamine-driven lowered serotonin in humans especially human males. The start dates of all war battles from 2001 to 2023 and from 1900 to 2023 as listed in Wikipedia are examined by month where the ranking, as well as medical research results, support the hypothesis.
Tracking in Context: Variation in the Effects of Reforms in the Age at Tracking on Educational Mobility
Authors: Grätz Michael , Heers Marieke
Published: May 2023

Previous research found that increasing the age at first tracking in an education system increased educational mobility. This research has implicitly assumed that these effects do not vary across contexts. Contrary to this assumption, we develop two hypotheses predicting such variation. The first hypothesis predicts that changes in the age at tracking increase educational mobility more for larger than for smaller changes in the age at tracking. According to the second hypothesis, reforms in the age at tracking only increase educational mobility if they occur in societies which put a high emphasis on equality of opportunity as a policy aim. We test these hypotheses by estimating the effects of reforms in the age at tracking, which occurred in five European countries (Belgium, Denmark, Finland, France, and Italy) in the 20th century, on educational mobility. We use data from the European Social Survey (ESS) and the Survey of Health, Ageing and Retirement in Europe (SHARE). The effects of the reforms are identified using a regression discontinuity design (RDD). A third hypothesis tests if the reforms increase educational mobility more among women than among men and if this is particularly the case in countries with a more gender egalitarian climate. Overall, the results reveal little cross-country variation in the effects of reforms in the age at tracking on educational mobility. In all analyzed countries there is an increase in educational mobility due to the reform in the age at tracking. In most countries, these effects do not differ between men and women.
A contemporary class structure: Capital disparities in the Netherlands
Authors: Vrooman J. Cok , Boelhouwer Jeroen , Gijsberts Mérove
Published: May 2023

The academic and public debate on social inequality has recently been fuelled by large disparities in income and wealth, profound changes in the labour market, and other emerging cleavages in post-industrial societies. This article contributes to the discussion by arguing that class divisions are theoretically based on four types of capital: people’s economic means, their social capital, their cultural resources, and the combination of their health and attractiveness (‘person capital’). From this premise, the social structure of the Netherlands is examined. A dedicated survey was linked to microdata from the national population register, tax authorities and benefit agencies. Using latent class analysis, we assess contingencies in the distribution of the different resources, and identify a structure consisting of six capital groups. The established upper echelon (15.5% of the adult population) has the most capital, followed by the privileged younger people (12.7%), the employed middle echelon (26.9%) and the comfortable retirees (16.6%). Total capital is lowest among the insecure workers (13.5%) and the precariat (14.8%). Each social class has a distinctive mix of the four types of capital, highlighting the need to look beyond economic differences in order to comprehend structural inequality. The results of this study also indicate that resource disparities between classes coincide with other forms of social hierarchy and contrasts by age. Moreover, the contemporary class structure is associated with divergent views and experiences among the Dutch. Classes with little capital tend to rate politics, society, and their own social position more negatively. In addition, they value self-enhancement and hedonism less than today’s upper classes and report lower levels of well-being.
Melting Curve of Cobalt using Molecular Dynamics Simulation
Authors: Bhusal Aabiskar , Adhikari Kapil
Published: May 2023

Molecular dynamics simulation is used to estimate the melting point of cobalt using the embedded atomic model (EAM) potential by heat until melting, void, hysteresis and interface methods. For instance, the estimated melting temperature are 2102 K, 1944.15 K, 1731 K and 1725±25 K using these methods, respectively. Then, the melting points at different pressures are calculated. A graph depicting the variation of melting point with pressure is drawn and compared with the available simulation and experimental results. The melting point at a low-pressure range is similar to the previous diamond anvil cell experiments. Besides, using the Simon equation, we calculated the melting slope at 0 GPa pressure of 36 K/GPa for one phase and 40 K/GPa for two-phase methods.

Authors: Ghimire Rishi Ram , Ghimire Anjila , Karki Dilip , Basyal Durga , Rai Krishna Bahadur
Published: May 2023

The biofloc system is a wastewater treatment technology and is used for fish farming by creating the artificial environment. Biofloc Technology (BFT) can enhance the water quality in aquaculture that introduces natural nutrient recycling characteristics with the induction of appropriate Carbon/Nitrogen (C/N) ratio. This study aimed to estimate the effect of BFT implementation on the water quality and production performance of common carp fishes using different concentration of carbon and to attempt a treatment of excess ammonia. The experiment was performed in four tanks (T1, T2, T3 and T4) containing the 10000 liter of water and 5000 shrimps on each tank that has a five weeks’ experimental treatment by adding the carbon as (25%, 30%, 35%, 40% and 45% of sugar) according to its feeding diet from sugar in the interval of one week. The ammonia level before and after the treatment with respect to the percentage of carbon from sugar addition on BFT signifies that the 40% of carbon (C:N ratio of 20:1) and 45% of carbon (C:N ratio of 23:1) have a better performance on the ammonia treatment than 25%, 30% and 35% of carbon. The change in the water's color from green to brownish indicates the protein conversion of ammonia, which informs that the water becomes higher in quality after treatment than it was before for the biofloc fish farming system. It also provides an information about the nitrification process that takes place when the water is treated with carbon derived from sugar. The findings of this study have important implications for the improvement of biofloc fish farming systems.
Critiquing the Postcolonial Nigeria in the Narratives of Ben Okri
Authors: Sharma Khum Prasad
Published: May 2023

The paper explores identity politics in the narratives of Ben Okri as they depict the Yoruba African myth. This study looks into the conditions of the culturally oppressed Africans in general and postcolonial Nigeria in particular that reframes the official version of colonial history. Myth offers reinterpretation and rethinking of the official colonial history in reclaiming the identity of the culturally excluded people with a variety of voices in response to the fictitious narrative. In line with this idea, I argue that the backdrop of postcolonial everyday life in Nigeria offers a chance to frame the topic of places more effectively. In order to comprehend and resolve the historical paradoxes and mysteries that are expressed in myth, magic and dreams, Thus, I analyze Okri’s book from the postcolonial perspective, considering sociopolitical and historical realities. In fact, Okri combines politics and the idea of history together, using his idea of an "inviolate" African consciousness as to show the foundation of how history dominates all other aspects. To justify my argument, this paper aims to examine how Okri reassesses history and encodes African consciousness in contrast to Western epistemology. Using African myths as a third eye in Okri’s novel, the paper also seeks to understand how Okri reimagines postcolonial potentials for his own Nigeria and, by extension, for the entire African continent.

The end-of-mission airlock: More than a homecoming tool for French Army soldiers
Authors: Ruelle Léa , Christmas Candice M.
Published: May 2023

LAY SUMMARY

French soldiers are prepared and trained to go on missions. Their time in theatres of war is part of a larger training program that includes preparation for the mission and return to civilian/garrison life. This program allows soldiers to enter missions in good condition and return to family and garrison at their best after having faced the stressors of war. Returning home sometimes involves an end-of-mission airlock between the geographical location of the mission and France where they can ease out of the daily routine of the mission and back into civilian/post-deployment routines. The entire training program involves what anthropology terms a ritual. This article studies the form of this ritual and the ways in which it impacts French soldiers. Comparing the lived reality of a group that underwent an end-of-mission airlock against a group whose airlock was cancelled revealed the components necessary for soldiers to transition out of a theatre of war. Results from this research offer a potential key to understanding the social mechanisms underlying the success of an end-of-mission airlock to best assist soldiers returning from war.
Well-being of Veterans with chronic pain with fewer activities limited by pain: Life After Service Survey 2019
Authors: Nazari Goris , Reyes-Vélez Julián , Thompson James M. , Sweet Jill , Miller Jordan
Published: May 2023

LAY SUMMARY

This study aimed to understand how common chronic pain is among Canadian Armed Forces (CAF) Veterans and the characteristics that were related with having fewer activities limited by pain using the Life After Service Survey (LASS) 2019. The LASS was a Statistics Canada telephone survey of CAF Veterans released in 1998–2018. About 1 in 2 (50.7%) reported living with chronic pain. CAF Veterans between 50 and 59 years who were female, employed, had higher education, higher rank, longer length of service, or higher income had fewer activities limited by chronic pain. High levels of mastery (feeling in control of factors affecting one’s life) was linked to having fewer activities limited by pain among people with moderate to severe pain. The strong link between higher mastery and fewer activities limited by pain points to a need for pain management supports addressing aspects of CAF Veterans’ well-being beyond pain severity and physical health.

Published: May 2023

The study considers management decisions that influenced the quality of education in the process of sports managers training under martial law, in particular, the organization of the educational process in a higher education institution and the terms of payment for educational services of students studying under a contract. The study was attended by applicants for the higher education of the first (bachelor’s) and second (master’s) levels of higher education and teaching staff of the Management of Physical Culture Department. The research used the following methods: methods of analysis, synthesis, generalization, comparison and methods of sociological survey. A survey of students was conducted after the resumption of the educational process under martial law. The most significant opportunities for online learning are considered the individualization of training, the flexibility of the training schedule in choosing the most convenient conditions (place and time), and the study of theoretical material on various online platforms. In their opinion, the lack of necessary equipment at home and the lack of constant access to the Internet have a negative impact on the organization of full-fledged distance learning. Monitoring the quality of education was carried out, the result of which showed the average grades of the success of students at the Management of Physical Culture Department. It is important to note that during martial law there was an issue of resolving problems with the payment of students for educational services, it turned out that some students lost the opportunity to pay for tuition for various reasons.

This article deals with issues aimed at the development of free wrestling, which is realized through increasing the spectacle and can be implemented only by the joint efforts of specialists in theory and practice. At the same time, the resolution of private tasks of improving a wrestler's skill should be carried out first of all taking into account the changes that UWW makes to the competition rules. An analytical approach to the management of the modern training process should be aimed at increasing the spectacle of competitive matches, which will allow wrestling to successfully compete with those sports that traditionally have the sympathy of spectators and fans.

Currently, UWW (International Wrestling Federation) is faced with a problem, the essence of which is that the numerous changes in the rules of competitions carried out under its leadership turned out to be largely fruitless and did not encourage athletes to engage in spectacular, highly technical wrestling. It must be agreed that the prestige of fighting against other sports is significantly reduced.

The entire evolutionary process of developing the rules of sports wrestling is conditionally divided into five stages: the fi rst (1896–1916); the second (1917-1937); the third (1938-1947); the fourth (1948-1969); the fifth (1975 to the present). Ever since the International Olympic Committee first approved the uniform rules for wrestling on the eve of the 1st Olympic Games in 1896, developed by French specialists Dublier, Rigal and Kristol, they have been constantly changing. They were changed and republished dozens of times.

Analyzing modern Scientific and Methodical, Special and reference literature, the members of the Research Group established, that the urgent issue of developing programs, methods, pedagogical conditions, organization models of the System of individual Physical Training of Military personnel of Institutions of the Security and Defense Sector of Ukraine with the use of modern training equipment (technical means of education) – an insufficient number of Scientific works are devoted to it.

The main goal of the study is to develop a Program of Individual Physical training for cadets of higher military educational Institutions of Institutions of the Security and Defense Sector of Ukraine (with an accented use of TRX training loops). Research methods: axiomatic, idealization, historical and logical, descent from concrete, formalization.

As a result of theoretical Research, an Experimental Program of Individual Physical Training of cadets of the Kyiv Institute of the National Guard of Ukraine was developed (with an accented use of TRX training loops). The results of theoretical Research are implemented in the System of Physical and Special Physical Training of cadet’s Institutions of the Security and Defense Sector of Ukraine.

Prospects for further research in the chosen field of Scientific Intelligence include approbation of the Program of Individual Physical Training of Future Officers (on the example of cadets of the Kyiv Institute of the National Guard of Ukraine) using TRX training loops.
Athletics in modern conditions

Published: May 2023

Athletics has undergone significant changes in recent years:

the athletics program includes a spectacular event - a mixed relay for women and men 4x400 m. The team consists of two women and two men. The peculiarity of this type is that the sequence of running one or another stage by women or men is not determined, but it is decided by the team leaders, which brings a certain intrigue to the competition;

changes were made to sports walking disciplines. The distance of 50 km for men is reduced to 35 km (which, in our opinion, will have a positive effect on the development of athletic walking and sports performance of athletes). But, at the same time, sports officials from the IAAF, either for reasons of gender equality or for some other reason, included a 35 km sport walk for women in the program, which, in our opinion, proves that such an approach equates physical, psychological and other opportunities for women and

The number of responsible athletics competitions for both young athletes and adults is increasing. But it should be remembered that the main task in the training process with young athletes is to lay a general physical, technical, special and psychological base.

Scientific and methodological data and practical experience show that the training of highly qualified athletes should be aimed at their performance at the main competitions of the year or quadrennial.

If it is necessary to perform in Diamond League competitions, commercial starts and others, it is recommended not to change the first part of the microcycle (Monday-Wednesday), but to make certain adjustments in its second half (Thursday-Saturday) in order to prepare the athlete for the competition.

The article defines the level of physical (somatic) health of students of the 1st year of a higher education institution. It was used the method of assessing the level of physical health G.L. Apanasenko.

The data on the distribution of the examinees according to the level of physical health allow us to state that 14.14% of female students and 2.39% of male students have a low level of physical health, 29.31% and 21.18% - below average, 44, 37% and 45.56% are average, 12.83% and 30.87% are above average.

The results of our research indicate that the average level of physical health prevails among first-year students. Unfortunately, among the students who took part in the study, there were not those whose level of physical health can be characterized as high.

The obtained results prove the relevance and expediency of developing measures aimed at improving the level of physical health of students of the 1st year of a higher education institution.

In our opinion, the prospect of further scientific research is the development of new methods of individualization of differentiated physical loads of students in the process of physical education depending on their level of health.
PUBLIC PARTICIPATION MODEL IN THE PREPARATION OF SHARIA-BASED ACEH QANUN: SPECIAL FOCUS ON THE ROLE OF THE ULAMA

Public participation in preparing legal products in Indonesia is essential for national and regional legislation. Although Indonesia is considered to have “achieved” democracy, many legislations do not agree with the people’s aspirations. This situation eventually led to a judicial review at the Supreme Court. It is expected that legal products in the form of sharia-based Aceh Qanun (regional regulation) can generate legal certainty and justice for society. This research was conducted in Aceh using a legal method based on a prescriptive approach. Results show that public participation in the preparation of sharia-based Qanun is more focused on issues that can give rise to differences of opinions amongst people from multi-religious backgrounds. The views are related to the norms in the bill in terms of fiqh (Islamic jurisprudence), local wisdom, and exploring problems and efforts to overcome them. The Majelis Permusyawaratan Ulama’s (Ulama Consultative Assembly/MPU) role in preparing Aceh Qanuns is limited to providing suggestions for the currently discussed bill. Unfortunately, the Aceh Qanun has not accommodated the rights of MPU to provide recommendations.  MPU’s  proposal for the Aceh Qanun bill  is in the form of suggestions because the ulama’s views do not bind the Aceh Governor and Parliament to enact the bill. The situation happens because the opinions are not in the form of a fatwa (legal pronouncement in Islam) but merely suggestions and recommendations.
SUB JUDICE AND GAG ORDER: THE RECENT DEVELOPMENT IN MALAYSIA
Authors: Mohd Sheriff Shukriah
Published: May 2023

High profile court cases always attracted media attention for public interest purposes. As a liaison between the court and the public, the media broadcast or report the case on their media channels and newspapers. From these broadcast and reports, the public receives sufficient information for them to formulate a certain opinion. Those who believe that they understand more would advocate their stance openly, usually comments through social media or actual publishers. However, many are not aware of the existence of a sub judice rule that prevents anyone from publishing any statement about the ongoing trial. This sub judice rule is imposed to avoid disruption of court proceedings and to avoid "trials by the media". In such circumstances, the parties to the suit usually apply for a committal order for contempt of court for breaching the sub judice rule. Alternatively, they apply for a gag order to stop anyone from publishing about the case. However, the court will only grant or reject the application for the gag order after examining and considering certain factors as enunciated in the case of Dato’ Sri Mohd Najib bin Hj Abd Razak v Public Prosecutor which has been applied in the case of Public Prosecutor v Arumugam a/l Dorasamy. This paper adopts doctrinal legal research methodology with case analysis approach. It delves into the analysis of the court’s decisions on the standards and tests laid down and evaluates the impacts on future cases. At the end of the analysis, it is established that the case of Dato’ Sri Mohd Najib bin Hj Abd Razak v Public Prosecutor has become the benchmark and precedent for all future gag-order applications. The outcome of this analysis is important to chart the application of the sub judice rule and a gag order in Malaysia.
