Typical Online Agreements and Associated Legal Challenges Confronting Consumers: A South African Perspective
Authors: Obioha Olubunmi Olukemi , Masumbe Paul S.
Published: August 2024

The emergence of the internet coupled with the rapid development in digital technology has revolutionalised the way things are done, including the economic activities of businesses and consumers. The ease and convenience offered via the electronic commerce platform has become a major motivation for its increasing use rather than visits to physical stores or places of business. Amidst the comfort, wider array of products and time saving benefits available to consumers in the digital marketplace, consumers are confronted with complex problems and challenges that offline consumers who interact with sellers’ face to face do not experience. Although there is subsisting legislation that regulates online transactions and agreement in South Africa, this seems to be inadequate to address the adverse situations consumers are exposed to while contracting electronically. This paper discusses the common forms of online contracts and the concomitant legal challenges affecting consumers while concluding contracts online in the South African context. Questions such as ‘which country’s law will apply on online contracts in cross-border contracts’ are some of the pertinent issues without clear cut answers. Divided into four parts, the first part deals with the legal principles regulating online contracts, part two tackles the validity of online contracts, part three deals with the legal challenges consumers face in online contracts in South Africa and the last part is the conclusion. The authors hope that this contribution would help stimulate the debate about online contracts with hopes of bringing the much-needed contractual certainty in this area of the law.

Authors: Tricia Ar Rohmah May ,   Program Studi Agroekoteknologi, Universitas Jember
Published: August 2024

One solution to solve pest problems in shallot cultivation is to apply the concept of Integrated Pest Management (IPM). An example of IPM that can be used is the use of light traps and sex pheromone traps, where both traps have been proven to be able to control the population of S. exigua Hubner in shallot plants. This study used RAK (Randomized Group Design) with 1 factor, namely the type of trap. The observation variables observed were the number of trapped imago, the number of egg clusters, the intensity of the attack, and production yield. Based on the results showed that S. exigua Hubner imago was more trapped in the lamp trap which amounted to 197.67 heads than the sex pheromone trap which only amounted to 14.01 heads. The number of egg groups in the sex pheromone trap plot was 0.28 and in the light trap plot was 0.18. The larval population in the sex pheromone trap plot was higher at 3.58 individuals than in the lamp trap plot at 3.16 individuals. The intensity of S. exigua infestation in the light trap plots was lower at 126.66 while in the sex pheromone trap plots, it was 155. The use of light traps to control the S. exigua population also provides higher production and profit than using sex pheromone traps.

Published: August 2024

Restorative Justice is a new approach emphasizing dialogue and peace in
crime resolution, prioritizing addressing the core issues between
individuals. In cases of assault, which involve unlawful acts causing harm
or injury, Restorative Justice is typically applied to minor cases. However,
Police Regulation Number 8 of 2021 expands Restorative Justice to encompass
both minor and severe assault cases, as implemented in North Halmahera
Police Resort. This empirical research collects primary and secondary data
through field studies and literature reviews, employing qualitative
analysis. Findings highlight the urgency of police implementation of
Restorative Justice in assault cases to achieve substantial and balanced
justice. Implementation has occurred in North Halmahera Police Resort in
accordance with Police Regulation Number 8 of 2021, yet faces challenges
such as socialization, cultural adaptation, and coordination between victims
and perpetrators. Future law enforcement policies based on Restorative
Justice must adapt to existing challenges, including wider socialization and
cultural adaptation. Understanding the importance of victims' and
perpetrators' presence in the Restorative Justice process also requires
enhancement.

Cases of sexual violence in Indonesia from year to year are increasing. The government also responded by passing the Law on Sexual Violence in 2022. It aims to ensure protection for Indonesian society, especially women and children, from the threat of sexual violence. But, there is a rule of jurisprudence whose essence is that the policies of the leader must cause benefit to his people. Therefore, this study aims to describe the purpose of establishing and ratifying the Sexual Violence Law and to analyze the benefits of the leader's policy in the passage of the Sexual Violence Law. The research method is descriptive normative by conducting literature studies from the main sources of the Academic Manuscript of the Law on the Crime of Sexual Violence. The results and discussion of this study state that the main content of the formation and ratification of this law is an effort to update a comprehensive legal umbrella that realize protection for society in general and victims of sexual violence in particular. When viewed from the rules of jurisprudence that theoretically the ratification of this law has implemented the policy of a good leader, namely based on the content of the articles in it although rudimentary. However, it practically cannot be categorized as a policy of a good leader because this law has just been passed and has not been implemented in society as a whole and only partially.

Indonesia, as a country with a strategic geographical position between two continents and two oceans, plays a role as a center of human crossing. Indonesia's vast sea area is an important potential to be developed, and President Joko Widodo initiated the World Maritime Axis policy to drive the economy in the sea area. Government agencies in the sea area are part of the ecosystem that supports policies in the sea area. Policies related to law enforcement in the sea area continue to develop along with the expansion of activities at the border. Immigration has a strategic role because it regulates traffic at the state border, maintains state sovereignty, and supports the implementation of sea area policies. This research aims to evaluate the strategic role of immigration by applying a progressive legal theory approach and using normative legal research methods. Progressive law returns the law to its substantial purpose, so that legal changes should not eliminate the substance. This research aims to answer the challenges of the times by adapting the law in accordance with the purpose of the law. In the context of international law of the sea (UNCLOS 1982), this research looks at the strategic role of immigration in law enforcement in the sea area, including the territorial sea zone and additional sea zone. The cooperation of law enforcement agencies in the maritime area is key to maintaining state sovereignty and security at the border.

Published: August 2024

Background: Assisted procedures in nursing involve scenarios where nurses are tasked with supporting physicians in the execution of medical procedures.  Nursing academics play a crucial role in cultivating appropriate attitudes towards nursing students. This study aimed to examine the soft skill elements in objectively structured clinical skill assessment on assisted procedures in the undergraduate nursing programme.
Methods: A clinical audit was carried out on the retrospective structured clinical skill assessment exam questions by using the clinical skill assessment index V (CSAI-V) instrument. A total of 3 assisted procedures set of exam questions were collected from 7 higher learning institutions in Malaysia where they offered the undergraduate nursing programme. The data were analysed descriptively.
Results: There were 3 assisted procedures out of 237 collected exam documents found and analysed in this study. The assisted procedures were grouped into 7 types to make them more specific. Although there are nine soft skill elements were identified in relation to assisted procedures, including communication, social and responsibility, critical thinking, problem-solving, teamwork, leadership, professional and ethical decision-making, numeracy, and interpersonal skills. However, none of the identified nine soft skill elements were found in the assessment rubrics.
Conclusion: Thus, the current assisted procedure checklist needs improvement, especially the soft skills components. Besides, higher-learning nursing institutions should visit and revise the content of their checklist and the related materials if they are concerned about quality graduates.
Parent-Child Relationship: Life Narratives of Elderly Parents as Care Receiver
Authors: Bermas Mary Joy , Baltazar Aira Juliana , Rungduin Teresita
Published: August 2024

Background: As children age, caring for their parents becomes a significant responsibility. In line with this, all parents as they age also undergo drastic life role shifts in their lives. From parents’ responsibility of caring for their children to children’s responsibility of caring for their parents. In the Philippines, an adult child shouldering the responsibility of being their caregiver is normal as it is a Filipino cultural trait that can be traced to the Filipino culture of “utang na loob.” 
Methods: To further explore and understand this concept, this study utilized a qualitative narrative inquiry design that focuses on understanding the life narratives of Filipino elderly parents regarding the parent-child relationship and care being a care receiver. A semi-structured and open-ended one-on-one interview was conducted with 5 Filipino elderly parents eligible for the participant’s criteria of this study.
Results: The findings showed that the development of the parent-child relationship from the role of parents as care providers until it shifts to being a care receiver, influences the type and quality of care the caregiver provides. Moreover, most Filipino elderly parents regardless of sex prefer their daughters as their primary caregivers as they elicit more caregiving behavior, unlike their sons.
Conclusion: In conclusion, the parent-child relationship plays a significant role in the care elderly parents receive from their adult childcare providers. Moreover, elderly parents consider caring for them as their children’s obligation towards them.

Human rights in the era of digital economy development: prospects and challenges.
Authors: Gorokhova Tetiana , Lazarenko Maksym
Published: August 2024

With the emergence and rapid development of the digital economy, new challenges to the protection of human rights arise. Digital technologies, artificial intelligence, big data, and other innovations offer many opportunities for the development of society, but they also threaten fundamental human rights and freedoms. One of the biggest challenges is the collection and processing of personal data. In the digital economy, large amounts of personally identifiable information are stored and used by companies and governments. Organisations and governments are making efforts to improve cybersecurity by developing and implementing strong security measures, including data encryption, multi-level authentication, and monitoring of cyberattacks. It is important to provide adequate cybersecurity training and education for both employees and citizens. This will help raise awareness of cyber threats and teach people how to protect their personal information. Artificial intelligence (AI) can lead to the automation of decision-making processes, which can affect people's rights and freedoms. For example, AI systems may be involved in decision-making processes regarding employment, credit scoring, or even offences. However, it is important to ensure that the algorithms are fair, transparent, and take into account the rights and needs of people. This article examines the challenges that arise in the digital economy, as well as the prospects and ways to protect human rights in this new environment. Foreign and domestic examples of the impact of technology development on human rights are summarised. Ways to improve the system of working with open data in Ukraine over the past 3 years are presented.

Evaluasi Pemilihan Electric Submersible Pump (ESP) Untuk Menggantikan Gas Lift (GL) Di Sumur X Lapangan Offshore Y
Authors: Nugroho Marsiyanto  , Eko Prastio  , Aly Rasyid
Published: August 2024

Well X is located in the offshore Y field, where there are 7 production wells, all of which use an artificial lift in the form of a gas lift. In this field, oil is produced from the N oil layer while the gas layer comes from the K layer. Well X was drilled in May 2013 with a target of N oil formation at a depth of 9,007 ft MD, slope (450) and 4-1/2" Liner completion. The initial production of well X was 1,632 BOPD; 5.3 MMSCFD; 0% BSW. Well X is the only well in the Y offshore field that does not penetrate the K gas formation, so gas production from nearby wells is used to produce oil from the N formation. well-to-well gas lift. Along with production time, the reservoir pressure in the N oil layer and K gas layer has decreased, so that oil production in well X has also decreased. With changes in company policy that optimize and increase gas production to increase gas sales to the industry around the company's operational areas since early 2017, the outgoing pressure on the Y platform has increased from 210 psi to 450 psi, causing a total oil well X could not pass through and produce due to high outgoing pressure on platform Y. Well X's last production data was on January 31 2017 with oil production of 179 BOPD and 1.25 MMSCD for gas production and gas lift injection of 0.75 MMSCFD, before finally shutting down.
The selection of another artificial lift as a substitute for the gas lift has been carried out to revive well X later. Based on the alloy table made by Weatherford for the selection of artificial lifts for conditions on the Y field platform, ESP has many advantages and appropriate flexibility compared to other types of artificial lifts. The ESP type D1050N which is a mix flow ESP has been selected and after installation in well X in August 2019 it has successfully revived with a production test of 885 BFPD, 681 BOPD, and 23% water content on September 3 2019. ESP in well X has been in production for 2 years, until finally experiencing a leaky tubing problem in September 2021 and requiring a new tubing replacement job along with a new ESP replacement to revive the X well.

The user subjected to many diseases during operation of the 'jack hammer such as (sever pain, numbness, pins, needles, loss of sense, and touch, loss of grip strength and painful wrist) .These diseases caused from the successive high amplitudes of vibration transferred from the jack hammer to the hand arm of the user. Results are presented to study the relationship between the excitation and the response of the system with the aid of Ansys program to give the indications of Eigen values and Eigen vectors deformation, to predict the behavior of hand-arm vibration, to control the risks from the vibration of the tool. This indicates that the high amplitudes of the jack hammer can be minimized by adding the dynamic vibration absorber which is a simply-spring mass system to the original mass system to make the system to two degree of freedom system and the entire system will have two Eigen values one above the excitation and the other under the excitation and this leads to eliminate the higher response and will have very small amplitude instead of very large amplitude to protect the users from the risks of hand arm vibration during the operation.
Laminar Fully Developed Forced Convection of Power Law Fluid in a Circular Tube
Authors: J. Shkarah Ahmed
Published: August 2024

Laminar forced convection heat transfer in a non-Newtonian fluid flow inside a pipe has been investigated analytically. Fully developed laminar velocity distributions obtained by a power-law fluid rheology model is used, and viscous dissipation was taken into account. The theoretical analysis of the heat transfer is performed under a constant wall temp. case. An important feature of this approach is that it permits an arbitrary distribution of the surrounding medium temperature and an arbitrary velocity distribution of the fluid. These techniques were verified by a comparison with the existing results. The effects of the Brinkman number and rheological properties on the distribution of the local Nusselt number have been studied. It is shown that the Nusselt number strongly depends on the value of power law index. The Nusselt number sharply decreases in the range of 0 < n < 0.1. However, for n > 0.5, the Nusselt number decreases monotonically with the increasing n, and for n > 1, the values of Nusselt number approach a constant value.

The aim of this work is to study the effect of changing welding current on the mechanical and metallurgical properties and choose the best welding current depend on result of study. The present work is an experimental study on effect of changing welding current on properties of seam welding joint for low carbon steel AISI 1005. Experiments results shows with increase welding current, hardness number will increase, also differentness in hardness number between weld nugget and HAZ (Heat Affected Zone) will increase and border of HAZ become bigger. Best mechanical results was achieved when welding current increased this doesn't mean that the highest current will become the suitable one, because the higher current will cause burin through in metal sheets and will cause leakage in products (liquid or gas storage tank), also will effect on grain size and microstructure due to changes in cooling rate, also the final shape of joints its important because most application of this type of weld is weight-goods industries (for civil using), so when use high welding current the final shape of joint will deform. Depended on above the best welding current rang is between 17 ? I < 19 K Amp.

Authors: A. Mashrei Mohammed
Published: August 2024

Columns are vertical compression members which carry primarily axial Compression load. The axial load may be associated with bending moments in one or two directions.Analysis of high strength concrete columns with circular cross section and spiral transverse reinforcement was presented in this paper.A computer program was used to do the analysis of high strength circular concrete columns. The variables considered in this article were concrete strength ranging from 55 MPa to 80MPa, volumetric ratios of steel used to confine the core concrete, amount of main reinforcement and axial load level. The results indicate that as increase in the amount of lateral steel, main steel, axial load and increase in concrete strength resulted in increases in strength capacity of column. The deformability of high-strength concrete columns can be improved significantly through confinement. The results obtained in this research are agreed with results obtained by experimental and analytical study conducted by other authors.

Authors: H. Elaikh Talib
Published: August 2024

In this study, the dynamic analysis of non-prismatic simply-supported Euler-Bernoulli beam subjected to non-concentric compressive axial force has been presented. Kinetic and potential energy expressions of the model are derived. Hamilton‘s principle is used to obtain the governing equations of motion. The fourth order differential equation with variable coefficient of the beam dynamics and buckling is solved using Differential Transform Method (DTM) to obtain mode shape, natural frequencies and buckling load of the system. The computer package Mathematical is used to write a program to calculate the natural frequencies, buckling load and the mode shapes. The effects of the taper ratio, eccentricity, and bucking load are investigated. The results are compared with the results of the analytical solution where a very good agreement is observed. The results show that the natural frequencies of prismatic and non-prismatic beam decreased when the compressive axial force increased. Also, the results show that when the taper ratio and eccentricity increased, the natural frequency of non-prismatic increases. The buckling load factor decreases when the taper ratio increases.
