CONCLUSION: It has good safety performance and is of practical significance.
Noncommutative rational Clark measures
Authors: Jury Michael T. , Martin Robert T.W. , Shamovich Eli
Published: July 2022

We characterize the noncommutative Aleksandrov–Clark measures and the minimal realization formulas of contractive and, in particular, isometric noncommutative rational multipliers of the Fock space. Here, the full Fock space over
$\mathbb {C} ^d$
is defined as the Hilbert space of square-summable power series in several noncommuting (NC) formal variables, and we interpret this space as the noncommutative and multivariable analogue of the Hardy space of square-summable Taylor series in the complex unit disk. We further obtain analogues of several classical results in Aleksandrov–Clark measure theory for noncommutative and contractive rational multipliers.

Noncommutative measures are defined as positive linear functionals on a certain self-adjoint subspace of the Cuntz–Toeplitz algebra, the unital
$C^*$
-algebra generated by the left creation operators on the full Fock space. Our results demonstrate that there is a fundamental relationship between NC Hardy space theory, representation theory of the Cuntz–Toeplitz and Cuntz algebras, and the emerging field of noncommutative rational functions.
Fourier non-uniqueness sets from totally real number fields
Authors: Radchenko Danylo , Stoller Martin
Published: July 2022

Let

K

be a totally real number field of degree

n \geq 2

. The inverse different of

K

gives rise to a lattice in

\mathbb{R}^n

. We prove that the space of Schwartz Fourier eigenfunctions on

\mathbb{R}^n

which vanish on the “component-wise square root” of this lattice, is infinite dimensional. The Fourier non-uniqueness set thus obtained is a discrete subset of the union of all spheres

\sqrt{m}S^{n-1}

for integers

m \geq 0

and, as

m \rightarrow \infty

, there are

\sim c_{K} m^{n-1}

many points on the

m

-th sphere for some explicit constant

c_{K}

, proportional to the square root of the discriminant of

K

. This contrasts a recent Fourier uniqueness result by Stoller (2021) Using a different construction involving the codifferent of

K

, we prove an analogue for discrete subsets of ellipsoids. In special cases, these sets also lie on spheres with more densely spaced radii, but with fewer points on each.

We also study a related question about existence of Fourier interpolation formulas with nodes “

\sqrt{\Lambda}

” for general lattices

\Lambda \subset \mathbb{R}^n

. Using results about lattices in Lie groups of higher rank we prove that if

n \geq 2

and a certain group

\Gamma_{\Lambda} \leq \operatorname{PSL}_2(\mathbb{R})^n

is discrete, then such interpolation formulas cannot exist. Motivated by these more general considerations, we revisit the case of one radial variable and prove, for all

n \geq 5

and all real

\lambda > 2

, Fourier interpolation results for sequences of spheres

\sqrt{2 m/ \lambda}S^{n-1}

, where

m

ranges over any fixed cofinite set of non-negative integers. The proof relies on a series of Poincaré type for Hecke groups of infinite covolume and is similar to the one in Stoller (2021).

Weak solutions and weak-strong uniqueness for a thermodynamically consistent phase-field model
Authors: Lasarzik Robert , Rocca Elisabetta , Schimperna Giulio
Published: July 2022

In this paper, we prove the existence of weak solutions for a thermodynamically consistent phase-field model introduced in [25] in two and three dimensions of space. We use a notion of solution inspired by [16], where the pointwise internal energy balance is replaced by the total energy inequality complemented with a weak form of the entropy inequality. Moreover, we prove the existence of local-in-time strong solutions and, finally, we show weak-strong uniqueness of solutions, meaning that every weak solution coincides with a local strong solution emanating from the same initial data, as long as the latter exists.
A Study on the Design Utilization of Image Based Social Network Service: focused on the use of 'Pinterest' by college students majoring in design
Authors:   Korea Institute of Design Research Society, Kim Byung Soo
Published: July 2022

Today, various communication activities represented by communication and exchange between people are being used as an important method for creative problem-solving in design. A social network service (SNS) called 'Pinterest' has the advantage of active communication and acquisition of visual information in the design field based on images, and is increasingly emerging. The purpose of this study is to examine the use cases and behaviors in the design field, where creative work is prioritized, in that design is the transmission and exchange of image information, and to explore the influence and direction it will have on basic design education. Accordingly, a questionnaire survey was conducted on 261 college students majoring in design, and meaningful data on the recent use of Pinterest was obtained. As a result of the survey, it was found that Pinterest, as a vast image-based SNS, has the ease of use to obtain design ideas suitable for one's major field, and actively participates in its use by logging in at least once a day. In addition, it was confirmed that most of the subjects recognized that Pinterest was more helpful in improving problem-solving ability and creativity than when not using Pinterest. It can be said that the significance of this study is that it has deduced a certain research result of acquiring basic data that can contemplate new possibilities of basic design education process and subject design in universities through this study.
A Study on the Embodying Expressive Characteristic of Minimal Art in the Residential Space by the Furnitecture
Authors:   Korea Institute of Design Research Society, Shim Hyung Joon , Lee Jae Kyu
Published: July 2022

As the efficiency and functionality are no longer important values at spaces for people, by the advancement of technology and changes in values, efficiency-oriented urban spaces are rapidly changing into experience-oriented spaces. However, the apartments, which occupy most of our residential spaces, still remain as a Standardized cuboid grid in the modern collective residential style. Compared to the commercial and cultural spaces which provide a rich spatial experience through various structures and formatives, residential spaces that created by combining the decorative symbols of furniture purchased for functions are relatively poor in terms of design. As a way to overcome the design limitations of standardized flat space, this study present the concept of a minimal art which provided a spatial experience by expanding a minimized object to the entire space. Through the case analysis of a furnitecture that has a functionality along with a volume which the concept of objects can be applied, expression characteristics which can play a 'functional role' necessary for housing, and a 'design role' as a formative object at the same time to overcome the design limitation of residential space will be studied.
A Comparative Analysis of the Emotions in the Molding Image of Air Purifier
Authors:   Korea Institute of Design Research Society, Kim Min Soo , Park Kyung Jin
Published: July 2022

This study was conducted to understand the differences in emotions, commonalities, and consumers' purchasing tendency for the product's molding image for professional designers and non-professional general consumers. For the data, the final adjective vocabulary selection and questionnaire were structured through a preliminary survey of 60 product design experts in the first collection, and statistical analysis was conducted using the SPSS 21.0 program after collecting final data for 81 experts and 93 non-experts. As a result, even with the same perceptual characteristics, there was a difference in the evaluation values of experts and non-experts, and there was a difference in adjectives showing dominant characteristics in the difference through gender comparison. Therefore, in this study, it was confirmed that in the process of envisioning the molding image, the individual sensitivity of the designer should be reflected and the visual difference from the consumer should be considered first. These results can be used as basic data in designing a molding image of a product that reflects the sensibility and views of experts and non-experts in the future.
Farmers using local livestock biodiversity share more than animal genetic resources: Indications from a workshop with farmers who use local breeds
Authors: Lauvie Anne , Couix Nathalie , Sorba Jean-Michel
Published: July 2022

Recognizing the products from farms that use local breeds is key to in situ conservation of local animal biodiversity. Recognition often focuses on a small number of specific breeds or products but could be expanded to include multiple local breeds and products. This paper shows that several farmers who use local breeds can share principles among the multiple dimensions of their farming systems. We analyzed the exchanges among nine farmers who use local breeds on the different dimensions of their farming systems at a workshop held in November 2017. We present the principles they shared and discuss (i) the fact that bringing the principles to the fore requires a collective participatory approach, (ii) the fact that shared principles may also concern dimensions often neglected in livestock farming systems approaches, and (iii) how a collective participatory approach can help recognize the products and activities of farmers who use local breeds.
Logic System Design for Fault Detection and Classification of Voltage Source Inverter Driving Induction Motor
Authors: Mahafzah Khaled A. , Obeidat Mohammad A.
Published: July 2022

Induction motors are commonly used in many different applications. The importance of these motors comes from their ruggedness, reliability, and low maintenance cost. Generally, the driving system of these motors can be vulnerable to injury of different types of faults during the operation, which leads to failure in continuous optimal operation of the system. This paper proposes a new simple algorithm to detect and classify the fault may occur in the driving system (in the Voltage Source Inverter VSI) of induction motor. The proposed method uses three parameters: First, the per phase average value of the stator current. Second, the Pulse Width Modulation (PWM) signal. Third, the switch voltage (drain to source voltage). The method is designed based on using the logic system. It is designed to decide whether the driving system is healthy or faulty. Moreover, the logic system can specify the fault location over the driving system. MATLAB 2020a is used to validate the results.
Visual Communication Design Collaboration with Occupational Therapy to Create Health Literacy Projects for Community Needs
Authors: Shirrell Elizabeth , Verbit Daniel , Chabot Monique C.
Published: July 2022

Low levels of health literacy directly correlate to increased mortality rates, decreased health outcomes and overall poorer quality of life. Many social determinants of health can place someone at a higher risk of low health literacy and the negative consequences of decreased skills in this area. Health literacy is a complex task that requires a multi-modal approach and interventions within a variety of spheres of influence in someone’s life. To address this issue in underinvested communities within their own city, teams of Visual Communication Design and Occupational Therapy students, with the support of their faculty and a librarian, worked together to identify a population of interest and pertinent health-related concerns. The result was an interdisciplinary team of students who utilised aspects of the Social Ecology Theory to create solutions and systems that utilised printed and digital modalities at the individual and community levels. This case study offers a model for interdisciplinary collaboration to address health literacy and improve the health outcomes of the population concerned.
La virtud no basta: la necesidad de una divulgación política de la ciencia del cambio climático
Authors: Vázquez Jiménez Heber
Published: July 2022

Las causas y los efectos del cambio climático se distribuyen de manera desigual entre los seres humanos. La narrativa que afirma que la solución a este problema socioambiental depende de la acción ética, virtuosa e informada de los individuos, no necesariamente es válida respecto a los impactos climáticos ya que éstos afectan a las sociedades en su conjunto y no sólo a individuos particulares. Un problema colectivo necesita acciones efectivas, coordinadas y regidas por reglas comunes, por lo tanto, políticas. Desde un enfoque centrado en el espacio, las acciones y los bienes comunes como criterio primordial de lo político, se aboga por una divulgación de la ciencia que fortalezca la resiliencia y disminuya la vulnerabilidad de las sociedades ante los impactos climáticos. Se exponen dos casos donde la comunicación o la falta de ella tuvieron consecuencias: (1) el caso exitoso del proyecto ESPA Deltas basado en la participación de las personas directamente involucradas (stakeholders); (2) las inundaciones de septiembre de 2021 en el valle del Mezquital, Hidalgo, México. Los ejemplos demuestran la necesidad de que la divulgación de la ciencia devenga políticamente activa, participativa y abierta al diálogo con los stakeholders para enfrentar exitosamente los impactos climáticos.

According to the Law on Private Security of the Republic of Serbia, the idea of private security involves, inter alia, providing services and enforcement of order maintenance in public gatherings (steward security service). Those services can be provided only by juridical persons and entrepreneurs registered for private security enforcement, as well as juridical persons and entrepreneurs that have formed the internal security organisation for their own needs (self-protective activity). However, the internal security services cannot provide their services to others. A juridical person or an entrepreneur may be engaged in activities of order maintenance in public gatherings only on the ground and in terms of written contract made on public gathering where their services are to be provided. Such basic concepts of order maintenance in public gatherings accepted by the Law on Private Security (2013) and confirmed by the Law on Public Gathering (2016) was essentially amended or call into question the amendments of the Law on Private Security adopted at the end of 2018. Those amendments now allow the organisers of public gatherings to organise steward security service of their own under certain conditions where the service will be provided by the stewards engaged by them. In this paper, the author analyses new solutions of the Law on Private Security referring to conditions and ways to provide maintenance order services in public gatherings and above all he considers the issue how those legal provisions effect the security of the public gathering attendants and third persons.

Temporary agency work is an atypical form of employment that is becoming more frequently used as an alternative to standard labour relationship. It is a complex, ‘triangular’ legal relationship, which involves temporary-work agency, employee employed by the agency and a user firm, to which the agency assigns the employee. This is not a new legal institute, but it has become popular and somewhat legally regulated in the territory of the former SFRY in the last ten years. The Republic of Serbia does not have regulations that would regulate this specific issue, although these agencies exist in practice and in large numbers operate in the labor market of Serbia. However, Serbia has taken a step on the road to that. Namely, the Ministry of Labor has published the Draft Law on Agency Employment with the aim of providing legitimate employment and guaranteeing a working position of the transferred workers who are guaranteed to the employees with the employer. By introducing the legal framework for work through the temporary employment agency, the labor legislation of the Republic of Serbia is harmonized with the international standards of the ILO and the EU. By clearly defining the temporary employment agencies and specifying the conditions for their work, the rights and obligations of persons who conclude an employment contract with the temporary employment agency for the purpose of assigning temporary employment to the employer, and other mutual rights and obligations of the employees, agencies and employers of the users, This area and maximally protect the so-called. agency employees. Namely, agency employees will receive equal wages and other basic working conditions, safety and health at work and other working conditions applicable to employees directly employed by the employer-user (according to which the order and instructions of the agency employee work).

According to earlier German legal solutions and court practice, letters and groups of letters could not be registered as a trademark except when they were imposed on the market. This restrictive approach is abandoned in European regulations, which also applies on the new German legislation. In other words, the letters and groups of letters are, from the point of view of registration, equal to other marks. However, in relation to the determination of the risk of substitution, trademarks that protect letters show some specificity, since the similarity of the letters is determined only on the basis of visual observation. Trademarks that protect letters generally have normal marking power. However, when there is an additional graphic stylization in addition to the letters, it is considered that, due to the shortness of the basic marking, image differences are significantly higher in comparison with the usual trademarks in the word. It must be borne in mind that the graphic stylization of the letters cannot be attributed to a superfluous meaning, unless it is unusually noticeable.

In this paper, the authors analyse the protection of a computer program in our law. There are numerous dilemmas in the United States of America, a significant representative of the software industry, as well, and also in the EU, concerning the legal framework in which legal protection can be realized. Both copyright protection and patent protection are currently accepted in legal practice. In our law, the basic form of protection of a computer program is copyright. Thus, by defining the notion of a computer program, through analysis of relevant sources of our law and listing the sources of the EU law, and due to hopes of being part of the European concept of protection of a computer program, the authors of this paper endeavour to draw attention to the current state when it comes to legal protection of a computer program by copyright or a patent in our law. The authors, mainly, analyse the subject and the assumptions for copyright protection of a computer program. Considering that copyright protection and patent protection of a computer program exist parallelly in practice, the authors discuss the connection between them too.

The development of the Internet creates new forms of communication, which provide the possibility of equalizing media content and global media influence. The Internet, as a new platform for broadcasting the program, changed the conditions of media functioning and created a disbalance between the freedom of the media and the rights of those to whom the information relates. The number of media service, providers and their need for profit-making has led to the fact that sensationalism has become a dominant way of attracting public attention. In this regard, the information from the private lives of individuals, whether ordinary citizens or public figures, come to the center of interest, and often cross the limits prescribed by the norms of the laws and codes of media service providers that regulate this field. Moreover, the quality of this information is controversial from the aspect of their accuracy (truthfulness) and completeness (objectivity). On the other hand, the existence of media legislation is not a guarantee of the existence of independent media. Media and media content can only be a facade of latent abuse of state, political, economic, or religious power. One of the ways to draw attention to contemporary social issues is an overflowing influence in the private sphere of citizens, and they themselves, often unconsciously, participate in this process, leaving data from their private lives, excessive interest etc. The lack of adequate and effective media legislation creates space for the state's arbitrariness and an unlimited and "discretionary" power of political power.

The subject of this paper is the analysis of the methods of regulating the advance decision of patients at the level of the Council of Europe and in the countries of German legal tradition in order to underline the significance of this institute and the predispositions for its validity and applicability in concrete medical situations. In the first part of the paper, the author presents and assesses the regulations related to advance decision making adopted under the auspicies of the Council of Europe, mostly with the aim of its recoginition as the expression of people's autonomy and the right to self- determination, but then, also, with the aim of establishing the principles on which the member countries base this institute in their national legislations. The second part is devoted to the analysis of the methods of regulating the advance directives and advance powers of attorney in Switzerland, Germany and Austria. In the conclusion, the author underlines the value of this institute and the need of the Republic of Serbia, the member of the Council of Europe, to harmonize its regulations on this matter with European standards. In that context, Serbia needs to acknowledge and establish the conditions under which a patient may in advance, in case of his subsequent incapacity, refuse or accept to be the subject of a certain medical treatment or designate a person who will make decisions on his behalf and under certain instructions related to his health. Here the author points to some issues that need to be adequtely solved , such as: the validity of declarations of consent, their registration, the monitring of their execution, etc.

Published: July 2022

Recent studies have reported that the use of language does not merely reflect on the communicative function, but also identifies the social status of the speakers. This research presents an explanation and of these findings in terms of the use of Jakartanese personal pronouns gue by non-Jakartan regarding the construction of social identity seen from the perspective of Social Identity Theory (SIT). Observation was employed to investigate the occurrence of this pronoun in conversations among the participants, and semi-structured interviews are used to find out the underlying motivations. Results show that by using gue, participants undergo the process of social Identity Theory and are able to enact stances, mostly familiarity and ‘coolness’ which becomes a prime aspect for them to construct self-identity.

Published: July 2022

Este estudo teve o objetivo de avaliar a relação entre as características de carcaça e qualidade de carne em suínos de uma linhagem comercial, utilizando a metodologia da Análise de Fatores (AF), e, posteriormente, estimar parâmetros genéticos utilizando os fatores extraídos da AF. O banco de dados avaliado inclui informações de 1407 animais e 20 características. Os fatores foram extraídos usando o método de componentes principais e o algoritmo de rotação varimax. Os parâmetros genéticos dos fatores (pseudo-fenótipos) foram estimados via inferência bayesiana sob um modelo animal multicaracterístico. Os cinco fatores extraídos explicaram 73% da variância original dos dados. O primeiro fator foi o que explicou a maior parte da variação, apresentando alta associação com todas as medidas de peso e por isso foi denominado fator “peso”. Já o fator 2 foi o segundo que mais explicou a variação dos dados e apresentou correlação positiva e forte com as variáveis relacionadas ao rendimento do lombo e do pernil, sendo definido como fator “rendimento”. O terceiro fator, denominado “lombo”, foi associado as características de área de olho de lombo e profundidade de músculo enquanto o quarto e quinto fator se associaram a características de qualidade e gordura da carcaça, sendo definidos como fator “qualidade” e fator “gordura”, respectivamente. Os cinco fatores biológicos extraídos neste estudo apresentaram herdabilidade variando de moderada a alta (0,16 a 0,61), indicando que a utilização destes fatores como critérios de seleção resultaria em ganhos genéticos para esta população de suínos. A utilização de variáveis latentes derivadas da análise fatorial, promoveu, de forma segura, a redução do número de características a serem avaliadas no programa de melhoramento genético de suínos. Palavras-chave: Correlação. Análise de fatores. Parâmetros genéticos. Seleção.

Recent outbreaks of crimean–congo hemorrhagic fever (CCHF) in Iraq
Authors: Al-Rubaye Dalal , Al-Rubaye Talib Saleh , Shaker Marwa , M Naif Hassan
Published: July 2022

Crimean-Congo haemorrhagic fever (CCHF) is an emerging zoonotic disease defined as a disease that passes from an animal or insect to a human. It is responsible for several deaths in humans, while the hosts, like cows, sheep, and goats are not affected. The CCHF was recognized for the first time in Iraq in 1979 where the virus was isolated from human cases and characterized. Since then, several small-scale outbreaks have been reported in 2019, 2021, and 2022. During this period, awareness workshops were conducted targeting government officials, veterinarians, medical doctors, and assistant staff. A strong collaboration strategy was put into place between these sectors together with the united nation office in Baghdad. These resulted in accelerating of the implementation of the amendment of the Veterinary Medical Progression Law 2021, establishing a supreme Committee for Epidemiological Disease Control supervised by the Council of Ministers and forming a collaboration crisis cell from Baghdad and other municipalities and ministries concerned, and placed detailed safety, one health and control measures for all parties involved. The current outbreak cases reached 90 cases with 18 deaths with the majority being in Thi-Qar Governorate. The current situation is difficult to deal with such a highly virulent virus due to the unavailability of an effective vaccine nor BSL-4 facility to safely deal/handle the virus in the country.
Porosity prediction using fuzzy clustering and joint inversion of wireline logs: A case study of the Nam Con Son basin, offshore Vietnam

Published: July 2022

Petrophysical properties such as porosity, permeability and fluid saturations are important parameters for reservoir characterisation, which can be determined by experimental constitutive equations between rock parameters and well logging data. Thus, the same rock properties might demonstrate different patterns, depending on the input and equations used. In this work, we used the cross-properties (a common set of rock properties) that influence different measurements to reduce the ambiguity of the petrophysical property definition. We present an approach of using fuzzy c-means clustering to classify the well logs and core data in clusters and then running inversion for each cluster. The obtained results allowed us to establish suitable parameters in constitutive equations, which usually vary with rock units that may relate to clusters. Testing data applied to the Nam Con Son basin show a square correlation coefficient of 0.66 between the predicted and core measurement, suggesting a reasonable matching of the testing data set.

The purpose of the study is to activate a well named X (for confidential reasons) in order to improve its production by proposing an electrical submersible pump. The nodal analysis is performed to understand the well’s condition and an economic evaluation is done to determine the applicability of the project. The initial completion data, the pump placement data and the economic data are considered and used as input in PIPESIM 2017 software for operations and simulations. The results obtained from nodal analysis show that the well is in a total depletion situation. Upon analysis, the electrical submersible pump type REDA S6000N with operational diameter of 5.38 inches is appropriately chosen and installed, resulting in a flowrate of 4,891.36 stock-tank barrels per day (stb/d) with a bottom pressure of 2,735 pounds per square inch (psi). A flowrate of 5,000 stock-tank barrels per day at a pressure of 2,707 psi is obtained after optimisation of the pump through sensitivity curves. The economic balance sheet presents a net present value of USD 110,718,250, showing the profitability of the project over a period of one year.

The present paper aims to design a continuous gas-lift system in order to activate the dead well X and optimise the recovery of hydrocarbons by gas injection. The data taken into account are those of the reservoir and the well. All the simulation operations and the well diagram are carried out with the PIPESIM 2017 2.0 software. Moreover, the nodal analysis of the dead well X is carried out by finding the injection pressure of the gas in the well. The number of valves to be installed, the optimal injection heights and the flow rates received by each valve are also included in the gas-lift device. Then the evaluation of the system performance as well as the sensitivity analysis are carried out to make it possible to fix the optimal flow rate of production. The results obtained show that for a continuous gas injection of 3 million standard ft3 per day (MMscf/d) per valve into the well with a wellhead pressure of 2,500 psi and an optimal flow rate of 2,718 standard barrels per day (STB/d), a profitability of USD 182,887,219 is obtained. In this field, this design can be applied to all wells having a production tube of 2.5 inches inside diameter. On the other hand, wells with different diameters will require a new evaluation.

Introduction: Failure to prepare students on fire safety and prevention in hostels adequately may result in various
losses not limited to life and health but also in terms of properties, intellectual properties, and morale. As practices relates closely to knowledge and attitude, the aim of this study was to investigate the level of their knowledge, attitude
and practices (KAP) in fire safety and prevention and its associated factors among hostels occupants in a university.
Methods: A cross-sectional study was conducted from March 2020 to October 2020, using online questionnaire
with five different sections to obtain respondents’ sociodemographic information, past-experiences and KAP related
to fire safety and its prevention. Results: Out of 283 students, the prevalence of having acceptable level of knowledge, positive attitude and good practice were 62.0%, 87.9% and 49.3% respectively. Multiple logistic regression
showed that non-Malay respondents were less likely (OR=0.301) to have acceptable knowledge level but those who
had past-experiences in fire drill training particularly hands-on in fire drill training have significantly higher odds
(OR=5.694; OR=2.353 respectively) of having acceptable knowledge in fire safety and prevention. Respondents who
had hands-on in fire drill training was the predictor for positive attitude (OR = 2.285); whereas respondents with
total household monthly income RM4,850-RM10,959 has 3.000 higher odds of good practice in fire safety and prevention. Conclusion: It may be worthwhile to explore other approaches in accident prevention besides KAP model
(attitude change via knowledge to modify behaviour) in this case, fire safety and its prevention.

Introduction: In cycling activity, having a good proper posture can reflect good performance and comfort of the cyclist. Incorrect posture will lead to future health problems such as back pain. On some occasions, the muscle activity of the cyclist also can be affected due to improper posture, non-ergonomic posture. Design and load can be major factors of injury as well. This preliminary study helped to identify and investigate the postural safety and ergonomic analysis of cyclist muscle activity during cycling. Methods: A questionnaire was used to get an overview and prior knowledge of postural safety and ergonomic of random cyclists on the university campus. Then, Surface Electromyography sEMG and postural angle from Kinovea software were used to measure and compare the results with and without load among cyclists. In this study, there was a significant effect of saddle height and pedalling on the cyclist’s body posture. This showed an optimum power and effectiveness performance while cycling. This led to comfort and reduce the chance of injury such as back pain towards cyclist. Results: Based on the results, the lower back muscles activity pattern for cyclists with the load was higher compared to cyclists without the load (the optimum saddle height was applied). The cyclist’s lower back muscles activity showed an increasing pattern overtime. Conclusion: Therefore, this study will be helpful to the cyclist to get awareness regarding correct posture safety and feel more comfortable when cycling. Further improvement should be taken for future enhancement of the findings.
The Effects of Input Enhancement on Incidental Academic Word Learning

Reading contributes to vocabulary development and is regarded as an efficient pedagogical approach to vocabulary learning. Through reading, learners are exposed to new words in their rightful context of use. This study investigates the effects of input enhancements on incidental academic word learning through reading English academic texts among English as a Second Language (ESL) undergraduates. The study compares different input conditions, gloss, contextual clue and no clue. Twelve academic words from Coxhead’s Academic Word List (AWL) were selected as the target words for this study. Three vocabulary tests were employed to assess academic words learnt incidentally from the texts in terms of their form, meaning recognition and ability to recall. Seventy-nine proficient and less proficient Malaysian ESL undergraduates participated in this study. Findings revealed that proficient participants recognised more target words compared to less proficient participants. In addition, gloss increases the noticeability of the target words, at least at the form recognition level. The study’s findings suggest that input enhancement would better impact vocabulary learning if integrated into a reading task or facilitated by vocabulary learning instruction.
Shorea macrophylla: Overview of Illipe Nut Producing Tree

Shorea macrophylla is also named as ‘Engkabang’ (Iban), ‘Kawang’ (Brunei), and ‘Tengkawang’ (Indonesia). It belongs to the Dipterocarpaceae family and is categorised under the genus Shorea, which can be found in the tropical rainforests in Southeast Asia. It prefers wet habitats, such as in periodically flooded alluvium and riverbanks. The tree size of S. macrophylla is medium or large; however, some researchers in Kalimantan claim it is a small tree. The flowering and fruiting systems of most Dipterocarps, including S. macrophylla, are irregular, but there is a massive flowering event once every few years. Its genetic structure is characterised by moderate genetic diversity within species and populations, as well as high genetic differentiation within local populations. Shorea macrophylla, also known as the Light Red Meranti, is a suitable timber supply for light construction work. It produces illipe nuts that are widely used as cocoa butter replacer fat. Wildlife eats the ripe illipe nuts, which contain a high oil content with mostly beneficial unsaturated triglycerides. The fat extracted from the nut are suitable for cosmetic application as it provides a good moisturising effect. Future investigation into the illipe nuts’ composition and other potential uses should be carried out.
