The main aim of this study was to assess the between-session reliability of performance and asymmetry variables between unilateral and bilateral standing broad jumps (SBJ). Twenty-four amateur basketball players completed two identical sessions which consisted of four unilateral SBJs (two with each leg) and two bilateral SBJs. Mean and peak values of force, velocity and power, and impulse were obtained separately for each leg using a dual force platform. Inter-limb asymmetries were computed using the standard percentage difference for the unilateral SBJ, and the bilateral asymmetry index-1 for the bilateral SBJ. All performance variables generally presented an acceptable absolute reliability for both SBJs with some exceptions for mean force, mean power, and peak power obtained with both legs. Asymmetry variables always showed unacceptable reliability and slight to fair levels of agreement in their direction except for unilateral SBJ peak velocity and bilateral SBJ peak power that showed moderate agreement for both SBJs. These results highlight that single-leg performance variables can be generally obtained with acceptable reliability regardless of the SBJ variant, but the reliability of the inter-limb asymmetries in the conditions examined in the present study is unacceptable to track individual changes in ground reaction force production.
El objetivo principal de este estudio fue evaluar la confiabilidad entre sesiones de variables de desempeño y asimetría entre saltos horizontales de pie unilaterales y bilaterales (SBJ). Veinticuatro jugadores de baloncesto amateur completaron dos sesiones idénticas que consistieron en cuatro SBJ unilaterales (dos con cada pierna) y dos SBJ bilaterales. Los valores medios y máximos de fuerza, velocidad y potencia e impulso se obtuvieron por separado para cada pierna utilizando dos plataformas de fuerza. Las asimetrías entre miembros se calcularon utilizando la diferencia porcentual estándar para la SBJ unilateral, y el índice de asimetría bilateral-1 para la SBJ bilateral. Todas las variables de rendimiento generalmente presentaron una fiabilidad absoluta aceptable para ambos SBJs, con algunas excepciones para la fuerza media, la potencia media y la potencia máxima obtenida con ambas piernas. Las variables asimétricas siempre mostraron una fiabilidad inaceptable tanto en magnitud como en dirección. Estos resultados ponen de manifiesto que las variables de rendimiento de una sola pierna se pueden obtener generalmente con fiabilidad aceptable independientemente de la variante SBJ, pero debido al cambio de dirección de la asimetrías entre sesiones, la fiabilidad de la ínter-asimetrías de las extremidades en las condiciones examinadas en el presente estudio son inaceptables para seguir los cambios individuales en la producción de fuerzas de reacción.

The action of bioactive peptides, such as antimicrobial peptides (AMP), in the human body is often compromised by limited residence time and stability in the target site. Bioconjugation of peptides to biomaterial surfaces is one of the strategies that may overcome these limitations. Herein, norbornene-chitosan (NorChit) microspheres were engineered to react with thiolated peptides by thiol-ene “photoclick” chemistry. NorChit microspheres were produced by spray drying and crosslinked with dithiothreitol (DTT) to prevent their solubilization. Microspheres with a diameter of 5 ± 2 µm showed round and smooth morphology with pockets over the surface that could be related with hydrophobic interactions between internal norbornene groups. Thiol-ene bioconjugation carried out using a fluorescent model peptide, showed a yield of 45%, whereas using the peptide but without UV exposure indicated a maximum of peptide adsorption of 30%. Altogether, NorChit microspheres show the potential for carrying bioactive peptides, which may open avenues for AMP activity onto harsh environments in the body.

Published: January 2024

In product marketing in Indonesia, halal is a fundamental matter, especially regarding food; this has been proven by previous research, while research on marketing drugs related to halal has yet to be found by researchers in previous studies. Given the circulation of drugs containing pig DNA, labels should be an essential thing to consider in every consumer purchasing decision because medicines are the same as a food whose use is consumed directly by the body. This study aims to analyze the effect of halal labels, promotions, service quality, brand image, and prices on consumer decisions in buying medicines at pharmacies in the Jember Regency. This type of research is associative research with a quantitative approach. The population of this study is consumers who buy drugs at pharmacies in the Jember district, which fall into the unlimited population category(infinite). The sampling technique uses the technique of nonprobability sampling with the approach of purposive sampling. Data collection using observation (observation), questionnaire (questionnaire) and literature study. This study uses multiple linear regression analysis. The data were tested using the classical assumption, Multicollinearity, Heteroscedasticity and Normality tests. The hypothesis test uses a partial test (t-test) and a simultaneous test (f-test). Use the coefficient of determination test (R2) to measure how far the model can explain the dependent variable's variation. The results of this study show that based on the significance value (Sig) on the halal label, the probability value is > α which is 0.326 > 0.05, so there is no significant effect between the halal label on consumer decisions on promotions and the probability value is > α which is 0.886 > 0.05. There is no significant effect between promotion on consumer decisions on service quality. The probability value is > α which is 0.002 <0.05, so there is a significant influence between service quality on consumer decisions; for the on-brand image, the probability value is > α which is 0.000 <0.05, then there is a significant influence between the brand image on consumer decisions, and at prices, the probability value > α is 0.128 > 0.05, so there is no significant effect between prices on consumer decisions in buying medicines at pharmacies in Jember district.

Published: January 2024

Abstract: The concept of justice is still relevant for debate, involving two political and legal perspectives. However, the two met in the context of resolving election disputes. Namely the election justice mechanism to resolve all forms of election disputes. This study will focus on resolving election result disputes, the 2020 Regional Head Election Results Dispute. John Rawls is a philosopher and political theorist who strongly influenced the tradition of justice theory. The concept of justice is offered from criticism of utilitarianism and intuitionism. Justice as fairness is a concept of justice that is procedurally fair but also justice that benefits as well as opportunities that are just (equal).
Purpose: This article aims to elaborate Regional Head Election Results Dispute from Rawls’ justice as fairness approach to resolve election disputes.
Design/Methodology/Approach: The research method used is qualitative research. Using a descriptive approach and literature study as data collection techniques.
Findings: There is still a serious debate about achieving the concept of justice between substantive and procedural justice in electoral studies regarding the equitable settlement of election result disputes. A just Regional Head Election Results Dispute indicates the degree of democracy in implementing direct, general, free, confidential, and honest, fair elections (LUBER JURDIL). Constitutional democracy is a meeting point between Rawls' democratic tradition and Plato's nomocracy.
Originality/value: Many articles on Regional Head Election Results Dispute philosophically explain Rawls’ justice as a fairness concept. However, this article explores the relationship between Regional Head Election Results Dispute phenomenon through Rawls’ philosophical concepts.

Improved Design of a Search and Rescue boat for the Royal Netherlands Lifeboat Institution
Authors: Keuning Jan Alexander 
Published: January 2024

The Royal Netherlands Sea Rescue Institution (KNRM) exploits a fleet of lifeboats around the North Sea coast of the Netherlands. The majority of this fleet consists nowadays of so called Rigid Inflatable Boats “RIB’s”. The largest vessels in the fleet are from the “Arie Visser” class, with a length of around 18.5 meters and a maximum speed of 35 knots. These are all weather boats on the North Sea and its coastal areas and self-righting. The Lifeboat Institution plans to replace the 10 boats in this class in the next 10 years. So an improved design (if possible) is sought for.
A design group has been composed for this purpose consisting of the Shiphydromechanics Department of the Delft University of Technology, Design office W. de Vries Lentsch, (the designers of the existing boats) and the High Speed Craft Department of Damen Shipyards.
Based on the requirements of the Sea Rescue Institution (KNRM) the group developed two new designs. These designs were initially derived using computer simulations and calculations. The emphasis in these new designs was on improved operability of the Search and Rescue boats in their typical working environment and improved habitability (i.e. noise and vibrations).
To assess the differences in performances of these designs in calm water and in waves an extensive test program has subsequently been set up and carried out with the three designs: i.e. the existing design Arie Visser and the two new designs.
Extensive full scale measurements on the existing boats of the “Arie Visser” class had already been carried out in the past and these results were used to specify the behaviour of the existing boats as a bench mark. Then the three designs, i.e. the Arie Visser, the Concept 1 and the Concept 2, have been tested for their resistance, sinkage and running trim in calm water. In addition their behaviour with high forward speeds in head irregular waves have been tested with emphasis on measuring motions and vertical accelerations.
Next their behaviour in high stern quartering, following and beam seas has been investigated with free sailing models in the Ship Model Basin of MARIN to compare the new designs with the existing one for difference in a possible tendency for bow diving and broaching behaviour in these high seas.
In addition severe breaking waves have been simulated in the towing tank and the models run through these both in head as well as following waves conditions.
The findings based on the computer simulations have been compared with the results from the measurements. The results of this research project will be summarized and presented in the present paper.
At-Anchor Wind-Induced Yaw Instability of a Monohull Motoryacht
Authors: Soja Jonathan , Bowles Jeffrey 
Published: January 2024

There is a delicate balance that must exist between the aerodynamic, hydrodynamic, and mooring forces acting on a floating body restrained by a single anchor (single point mooring). If the balance is not achieved, the floating body will exhibit undesirable motions which have been referred to by the industry as horsing, fishtailing, kiting, and “sailing about at anchor.” Significant work related to the offshore oil industry documents these yaw instabilities on single point moorings; however, the knowledge base is not very well disseminated outside of the offshore sector, especially when considering that vessels of all types are susceptible to this phenomenon.
When the aerodynamic forces dominate the hydrodynamic and mooring forces, no matter the vessel type or configuration, the potential for the undesirable motions to occur exists. With the increased desire for larger interior volumes on vessels, hull and superstructure windages are trending larger and the aerodynamic forces acting on the vessels are becoming more significant, making the phenomenon a more common occurrence.
This paper provides an introductory overview to the phenomenon of yaw instability of a vessel on a single point mooring, and documents a technical investigation into the phenomenon. The research program conducted consists of full-scale sea trials, aerodynamic analysis through computational fluid dynamics, numerical simulations, and physical scale model testing. Results of the research program are presented which demonstrate successful replication and mitigation of the motions.
Motion Control for Small Fast Boats in Following Seas
Authors: Keuning J. A. (Lex) 
Published: January 2024

The behavior of fast and relatively small ships in large following seas has been a serious concern for the operators for a long time now due to the possible occurrence of “broaching”. Due to the relatively low encounter frequency of these fast boats with respect to the large and high following and stern quartering seas an intensive coupling between surge, roll and yaw may occur which may finally lead to a capsize of the boat. The applied (and necessary) rudder control using the conventional rudder layout to prevent the excessive yaw motion may even further aggravate the situation.
In an extensive research project the Delft Ship hydromechanics Laboratory of the Delft University of Technology has constipated, developed, tested and evaluated the application of a “bow rudder” to control this situation much better. In conjunction with the conventional rudders (or waterjets) at the stern the application of such a bow rudder yielded a significant (up to 50%) reduction of the both the yaw and the roll motion in these conditions. Comparative studies of models with and without such a “bow rudder” in the towing tank showed no tendency to broaching of the boat with bow rudder at all any more. In a later design evolution this bow rudder has evolved into the development of a “retractable bow rotor”, using the well-known Magnus effect as the lift (steering) force generator. This made it possible to retract the rotor when it’s application was not asked for and thereby eliminating any possible negative effect on the resistance of the boat.
The results of earlier studies will be shown in this publication together with the obtained results of various towing tank test campaigns carried out to develop the rotor and also some different design concepts. Based on these tests an actual rotor has been build and placed on board a real ship, a DAMEN Stan Pilot 2205, a pilot boat of circa 22 meters long and capable of attaining a maximum speed of 25 knots. Herewith full scale measurement have been carried out at the North Sea and these results will also be presented here. In addition the results of tests specially of interest for a typical Pilot Boat operation will be shown.
