Abstract

Thorax radiology examination in children is one of the most frequently performed examinations in hospitals. However, the radiation used in this examination can potentially disrupt the growth and function of the child's imperfect organs. Therefore, patient radiation protection is very important to optimize the radiation dose received. The Nuclear Energy Regulatory Agency (BAPETEN) has set reference level values ​​in the form of IDRL (Indonesia Reference Level) for Diagnostic Radiology, including CT-Scan, Mammography and Fluorescence, as well as DRL (Diagnostic Reference Level) values ​​for children's thorax. The radiation dose received by the patient must be considered to avoid negative effects on the child's growth. This study aims to determine the measurement of radiation dose on chest radiography examinations of children. In this study, we will compare the radiation dose received by pediatric thorax patients based on the radiation dose standards set by UNSCEAR in 2000. Apart from that, we will also compare the radiation dose received by pediatric thorax patients with other studies. It is hoped that the results of this research will provide useful information and input for hospital diagnostic services in optimizing the radiation dose received by pediatric patients.

Abstract

Dacryocystography examination is the examination of the radiologist to show the nasolacrimal duct by using a positive contrast medium. The purpose of this examination is to describe the system of tear duct blockage and the level of blockage. This research method is descriptive with aproachcase study conducted in RSUP. Dr. WahidinSudirohusodo Makassar on Juni 2019. The inspection technique is done by using the projection Antero Posterior (AP), which contrast material is inserted throught the tear duct in the lacrimal punctum which empties into the concha nasalis inferior. From the result of the examination has been done, it can be concluded that the contrast as much as 1 cc inserted throught the superior lacrimal punctum, contrast restrained and spilled out. Contrast as much as 1 cc inserted throught the inferior lacrimal punctum, the contrast seems to fill out the inferior palpebra area. From the research, lacrimal duct obstruction impression superior and inferior.

Abstract

One factor that plays an important role in the quality of radiodiagnostic examination results is radiographic contrast. When examining thick objects, radiographic contrast will decrease as a result of the large amount of scattered radiation originating from the object and reaching the film. To obtain optimal radiographic contrast on thick objects such as the head, it can be done in various ways, including using a grid. The grid is a tool that functions to absorb scattered radiation but can still transmit primary radiation. Examination of the head is done to get the head radiograph and to determine any abnormalities or diseases of the head. This examination was performed using the grid and without grid to compare the better results of radiographs. Radiographs results were obtained using processing film, Computed Radiography (CR). This research used descriptive study conducted at Hospital Tk. II Pelamonia Makassar on January 2020. Based on the results of the research which conducted for examination of the head using grid and without grid on CR cassette obtained that the result of radiograph examination of the head using a grid was better.

Abstract

This study aims to obtain emprical evidance of the effort of liquidity, activity on the company’s capital structure. The population used is the non-building construction sub-sector for the 2018-2022 period. The Sampling technique used is porposive sampling with certain criteria. So that 10 companies were obtained according to the criteria. Data analysis technique used in research include multiple linier regression analysys and path analysis. The result of the research test show that liquidity and activity have a significant impact on the capital structure of non-building cconstruction sub-sector companies. In addition, activity variables as intervening variables are able to mediate the relationship between liquidity and capital structure.

Abstract

During the Covid-19 pandemic in 2020, the oil and gas industry experienced decreased demand, decreased prices, and overproduction (although production decreased). Some oil companies themselves have reduced exploration, including stopping new oil drilling projects. When Covid-19 began to subside, the oil and gas industry again faced the next problem, namely post-pandemic. World oil demand is slowly increasing from a very low level and the impact is that the global economy is starting to return to normal. This research was conducted on the Oil and Gas Subsector in companies listed on the Indonesia Stock Exchange for the 2017-2021 period. The data population is 17 companies and the sample used is 8 companies using purposive sampling method. The variables used in this study are the Solvency Ratio, and Firm Value and Profitability Ratio as intervening variables. The test was carried out by conducting a classical assumption test (normality, multicollinearity and heteroscedasticity) and path analysis test using the SPSS 25 application. The results obtained after conducting research are Solvability has no effect on Profitability, Profitability has no effect on Firm Value, Solvability has an effect on firm value and Profitability cannot mediate the influence between Solvability and Firm Value.
