This research concludes that certificate writing is dominated by men (single) due to religious/belief, socio-cultural and economic factors. Writing a single subject on the certificate doesn’t match the current principles because there is no match physical data and juridical data. Writing names singularly or plurally on a certificate has advantages and disadvantages in terms of the subject, rights and obligations and transferred. Singular and plural subjects physically have the right to use objects, but legally the subject written on the certificate has the right to transfer land rights. The rights and obligations of singular and plural writing are burdened by PBB and BPHTB. In single writing, during the process of transferring inheritance rights, the married couple is burdened by BPHTB unanimously without considering their roles. BPHTB calculation in plural writing reduces the payment obligations of the husband/wife because their role is recognized. When transferring rights to merge objects, objects that are recorded plurally, the merger process is simple because it does not require a name change, whereas in single writing adjustments are made and payments of taxes and other fees.

Methods for assessing remote rockfall hazards above transport corridors
Authors: Field David , Hunter Andrew
Published: August 2024

Many roads and railways in Australia, particularly in eastern Australia, traverse steep natural escarpments. These roads are commonly associated with rockfall hazards that pose risks to road users and can also cause significant disruption to these transport assets. The source of these rockfalls can originate considerable distances upslope of roads, often amongst densely forested slopes on steep, mountainous terrain that is difficult to access. Given these constraints it is often difficult for practitioners to assess rockfall hazards and ultimately risks, based on inspections undertaken from within transport corridors and can result in risks being poorly understood. Emerging technologies such as high resolution unmanned aerial vehicle (UAV) mounted lidar acquisition, advances in photogrammetry and three-dimensional rockfall modelling software offer the potential to greatly enhance the understanding of slope processes above roads across large distances. This paper presents the results of a study that investigated the use of a range of technologies aimed at acquiring high quality ground survey data and better predicting the runout behaviour of rockfalls originating from natural escarpments and the likelihood of these reaching a road. This included a detailed study of two large rockfalls above a road in the Sydney Basin. The results of the three-dimensional rockfall modelling are compared with empirical methods traditionally used to predict the runout distance of small rockfalls. When used in conjunction with more traditional engineering geology approaches, the application of emerging technologies can greatly improve the efficiencies and quality of rockfall hazard and risk assessments.

DESAIN SOLAR CHARGE CONTROLLER METODE FPPT ATAU PELACAKAN PENGISIAN DAYA PENUH UNTUK PANEL PV DAN POWER STATION PORTABEL
Authors: Agus Agus Nurcahyo
Published: August 2024

Solar Charge Controller (SCC) PWM available on the market generally must be installed by connecting the SCC to the battery using the shortest possible power cable. This is intended to reduce the problem of the battery voltage measured at the SCC and the voltage measured at the battery poles having different values ​​when charging the battery. The difference in voltage values ​​can cause errors in indicating the battery voltage in the SCC so that battery charging is not fully optimal, especially when the battery is close to full. The application of separate SCCs to portable PV panels and portable power stations requires the use of long power cables between the SCC and the battery in portable power stations. Therefore, an SCC design is needed that can overcome this problem. In this study, the SCC Full Power Point Tracking (FPPT) design is proposed. One way to accurately indicate the battery voltage in the SCC is to disconnect the DC current from the PV panel to the battery in a very short time accompanied by measuring the battery voltage, this disconnection and measurement are carried out periodically. The results of the voltage measurement are used to determine whether the battery is fully charged or not. The SCC FPPT made here can provide power up to 98.3% even though the battery is detected as almost full by using a 60 cm long cable with a cross-sectional area of ​​1.5mm2 from the SCC to the battery

A note on the existence of solutions to the semi-affine variational inequalities problems
Authors: Vu Van-Dong
Published: August 2024

The semi-affine variational inequality problem offers a general and versatile framework applicable to many problems in economics, mathematical physics, operations research, and mathematical programming. One of the important applications of the semi-affine variational inequality problem is quadratic programming. It is well-known that the first-order necessary optimality condition for a constrained optimization problem can be rewritten as a variational inequality. This paper investigates the existence of solutions for the semi-affine variational inequality problem in the finite-dimensional Hilbert spaces. Under suitable conditions, we show that the solution set of the semi-affine variational inequality problem is nonempty. The obtained results contribute to and complement the existing literature.

Authors: Park Ye Seul , Park Ju Hee
Published: August 2024

Objectives: This study examined the effects of bullying victimization on cyberbullying perpetration and investigated whether hopelessness and time spent online sequentially mediate the relationship between bullying victimization and cyberbullying perpetration among upper elementary students.Methods: The participants were 596 upper elementary school students {5th and 6th graders; 291 boys (48.8%)} from Seoul and Gyeonggi-do. The data were collected through a self-report questionnaire and analyzed using SPSS 26.0 and PROCESS macro version 4.3 (Model 6) by Hayes (2017).Results: First, bullying victimization positively influenced cyberbullying perpetration. Second, the sequential mediating effects of hopelessness and time spent online were significant. Lastly, time spent online mediated the effect of bullying victimization on cyberbullying perpetration, whereas hopelessness did not mediate this effect.Conclusion: These findings indicate a link between bullying victimization and cyberbullying perpetration. Therefore, it is recommended that cyberbullying prevention programs include strategies to reduce bullying victimization. Furthermore, high levels of hopelessness resulting from bullying victimization may lead to excessive internet use, increasing the likelihood of cyberbullying perpetration. Thus, victims need to be informed of about the importance of reporting bullying incidents to adults such as teachers, counselors, or parents. Additionally, if victims already exhibit high levels of hopelessness, it is necessary to encourage them to participate in evidence-based programs. Finally, the significant mediating effect of time spent online suggests that monitoring and intervening in victims’ online activities are crucial for reducing the likelihood of cyberbullying perpetration. These efforts may help prevent victims from spending excessive time online to relieve their hopelessness and from perpetrating cyberbullying.
