Introduction: It is universally accepted that the posteroanterior skull radiograph shows a lower degree of distortion than other radiographic images, so that measurements on it are considered reliable. Objective: To determine the percentage of distortion in the different facial regions of the postero-anterior skull radiograph. Methods: Thirty human skulls with their jaws were divided by three horizontal and four vertical planes into fifteen quadrants; there were ten in the skull and five in the jaw. On each of them a steel wire was placed in vertical and horizontal positions and their length (actual measurement) was measured. Each set was X-rayed in posteroanterior projection and the length of the wires was measured in the image (radiographic measurement). Results: It was not possible to measure in the lateral quadrants of the skull. The horizontal measurement in the right and left lower intermediate quadrants of the skull and in the intermediate and lateral quadrants of both sides of the mandible is not reliable; in the median quadrant of the mandible it is minimized; in the right and left upper intermediate and median quadrants of the skull and in the median of the mandible it is magnified. Vertical measurements in all quadrants are reliable; in the right and left upper intermediate and left upper and middle quadrants of the skull and in the right and left middle and lateral quadrants of the mandible it is magnified; in the lower intermediate and upper and lower middle quadrants of the skull and median of the mandible it is minimized. The least distortion for both measurements occurs in the upper median quadrant of the skull. Percentages of distortion are reported for each quadrant. Conclusions: Distortion is present in the posteroanterior skull radiograph and varies from one region of the face to another.

In the current era, electromagnetic radiation is everywhere. Every day electromagnetic radiation and static electricity caused by a variety of hazards. So, anti-electromagnetic radiation and anti-static awareness gradually enjoys popular support, more attention are gained by people on the anti-electromagnetic radiation and anti-static. This caused radiation protection and anti-static clothing industry’s rise by the day. Radiation protection and anti-static clothing will enter various households to provide a certain amount of protection to the people's health. We discuss two parts in this paper, specifically from the effects of the electromagnetic radiation and electrostatic effects which started on radiation clothing and anti-static clothing. The main contents of this paper are as follows: The first part of the definition of electromagnetic radiation and its brief introduction, while explaining the types of electromagnetic radiation and electromagnetic radiation sources in daily lives, followed by the emphasis of serious harms on electromagnetic radiation on human health It is precisely because of electromagnetic radiation on people's lives have serious threat, that makes the development of radiation protection. This follows the basic introduction of the radiation suit and the development of radiation protection clothings. The development of radiation protection suits is an established industry. Materials made of radiation protection are constantly changing, but their basic working principle has not changed. Followed by the introduction of the basic principles of radiation protection clothings, we theoretically present specific analysis and demonstration. However, the theoretical analysis and practice is often consists a certain gap, so we highlight a few actual situations on the impact of radiation protection clothings. Finally, we present a simple discussion on wide range of applications of radiation protection clothings. The thought process of second part is similar as the first part, respectively, we introduce the health hazards and the impact on people's lives of electrostatic effect and static electricity . Followed by that it is the basic principles, relevant analysis and discussion of anti-static clothing Finally, we provide the detailed explanation of the application of anti-static clothing.

Alginate-silver nanocomposites in the form of spherical beads and films were prepared using a green approach by using the aqueous extract of Ajwa date seeds. The nanocomposites were fabricated by in situ reduction and gelation by ionotropic crosslinking using calcium ions in solution. The rich phytochemicals of the date seed extract played a dual role as a reducing and stabilizing agent in the synthesis of silver nanoparticles. The formation of silver nanoparticles was studied using UV-Vis absorption spectroscopy, and a distinct surface plasmon resonance peak at 421 nm characteristic of silver nanoparticles confirmed the green synthesis of silver nanoparticles. The morphology of the nanocomposite beads and film was compact, with an even distribution of silver nanoclusters. The catalytic property of the nanocomposite beads was evaluated for the degradation of 2-nitrophenol in the presence of sodium borohydride. The degradation followed pseudo-first-order kinetics with a rate constant of 1.40 × 10⁻³ s⁻¹ at 23 ℃ and an activation energy of 18.45 kJ mol⁻¹. The thermodynamic parameters, such as changes in enthalpy and entropy, were evaluated to be 15.22 kJ mol⁻¹ and −197.50 J mol⁻¹ K⁻¹, respectively. The nanocomposite exhibited properties against three clinically important pathogens (gram-positive and gram-negative bacteria).

Indonesia’s stock market has seen an increase in investment due to the ease of investing and the availability of information about stocks on different social media platforms. This research uses a social network approach to analyze overconfidence behavior in millennial stock investors. This research uses a descriptive quantitative method. The population used in this study are capital market investors in the Greater Solo area who are millennials (<30 years). The number of stock investors in the Greater Solo area is 60,542 investors. The sampling technique in this study was non-probability sampling using purposive sampling. This research uses the AMOS SEM (Structural Equation Model) analysis tool. The conclusion of this study is that millennial investors’ overconfidence behavior increases influenced by financial literacy. investor skills. family ties and friendship ties. The contribution of this research can be applied to understand and educate millennial investors in order to overcome overconfidence behavior so that they can anticipate the losses received. This research may have implications for improving Behavioral Finance Integration Incorporating insights from behavioral finance into investment strategies can help mitigate the negative effects of overconfidence. The limitation in this study is that the scope used in the study is only in the greater solo area.

The Trans Sumatra Toll Road (TSTR) is a mega toll road project with an assignment State-Owned Enterprise (SOE) scheme in Indonesia. In its development, TSTR has several limitations, including funding, low investment feasibility and the un-optimum implementation of land value capture (LVC). This has the impact of delaying the completion of project development, decreasing the performance of toll road developer companies and even causing bankruptcy. LVC is an alternative funding scheme proven successful in other countries such as Hongkong, England and Vietnam. Several transportation projects based on transit-oriented development have successfully achieved profits using the LVC method. With a low project feasibility, the implementation of the Road Plus Property Developer (RPPD) business model is expected to be a solution to improve investment performance in the TSTR project. RPPD is defined as an assignment scheme toll road business model based on LVC implementation. This research aims to develop policies for implementing the RPPD business model on toll road SOE-assigned schemes. The data was collected by in-depth interviews with experts in two stages. The data analysis method used is Soft System Methodology (SSM). This research produces two recommended actions: ratification of the Presidential Regulation regarding the implementation of LVC and institutional transformation of regionally owned business entities in the property sector. It is hoped that implementing the RPPD policy will become a priority in completing the TSTR project.

As a public opinion position to convey the spirit of the Party Central Committee and national policies, the Integrated Media Center plays a vital role in publicity work. However, there are also some problems in the process that hinder further development. The integrated media center has the advantages of understanding the direction of publicity, familiar with the local economic and cultural development, and mastering the production of short videos. If the integrated media assists in the production and promotion of short videos, it will have better publicity effects. This article analyzes the problems in the promotion process of short videos for rural users, in order to establish effective working ideas for the media center and promote local cultural inheritance and innovation.
