Purpose – This study is to provide information or description of the effect of firm size on the value of the company-mediated profitability in mining sub-sector companies listing on the Indonesia Stock Exchange period 2011-2015Design/methodology/approach – The sample selection in this study using nonprobability sampling, and obtained as many as 24 companies from the total population of 40 companies. Data analysis methods used are descriptive statistics, classical assumption test, and Path Analysis, and Sobel Test.Findings – The size of the company has a positive and significant impact on stock prices, firm size has no effect on profitability, profitability has a positive and significant impact on corporate value. While profitability is not able to mediate the relation of firm size to firm valueResearch limitation/implications – This research is only the mining sub-sector, while the problem on the value of the company occurs also in other sub-sectors. Then, the proxy used is only one for each of the observed variables. The period of 5 years is from 2011 to 2015, so the data taken there is less likely to reflect the condition of the company in the long run.Originality/value – Located on a research model that includes profitability as an intervening variable in the research modelKeywordsCorporate Value, Firm Size, Profitability

Kecemasan masuk sekolah secara sederhana dapat diartikan sebagai bagian dari kecemasan umum akibat rasa takut berpisah dari ibu atau pengganti ibu, dan ketidakmampuan berdiri sendiri. Kecemasan yang dialami oleh anak usia prasekolah akan berisiko mengganggu tumbuh kembang anak. Pada anak, membaca merupakan bagian dari fokus perkembangan. Biblioterapi merupakan salah satu bentuk dari terapi yang melibatkan buku untuk membantu anak dengan masalah mental maupun emosi. Tujuan penelitian ini adalah untuk mengetahui pengaruh biblioterapi terhadap tingkat kecemasan pada anak usia prasekolah di PAUD Terpadu Aisyiyah Nur’Aini Yogyakarta. Penelitian ini adalah quasi experimental dengan pre-test dan post-test design tanpa kelompok kontrol. Penelitian ini dilakukan di PAUD Terpadu Aisyiyah Nur’Aini Yogyakarta pada bulan September 2015 dengan besar sampel 27 responden yang pada pelaksanaan biblioterapi dibagi menjadi tujuh kelompok kecil. Instrumen pengukuran tingkat kecemasan yang digunakan adalah SCAS (Spence Children’s Anxiety Scale) yang ditulis oleh Susan H. Spence tahun 2000. Hasil analisis data menggunakan uji Wilcoxon, dengan nilai p = 0,000 < 0,05. Kesimpulan dalam penelitian ini adalah biblioterapi berpengaruh secara signifikan terhadap penurunan tingkat kecemasan anak usia prasekolah di PAUD Terpadu Aisyiyah Nur’Aini Yogyakarta.

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.

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.

Dengue Hemorrhagic Fever (DHF) is an infectious disease that can be fatal in a relatively short time. This disease is classified as "difficult to differentiate" from other dengue fever diseases. If without quick and appropriate treatment, the sufferer could fall into an even more fatal condition. And generally the supporting action taken is an X-ray examination of the chest to assess the presence of fluid in the pleura as a result of the Aedes Aegypti mosquito virus. The purpose of this research is to know the Comparison of Radiographic Results of Pleura Effusion on Right Lateral Decubitus Projection and LLD ( Left Lateral Decubitus ) in DHF ( Dengue Haemoragic Fever ) case. This research was conducted in RSU.Wisata Radiology installation of Universitas Indonesia Timur with quantitative research method with experimental design approach. Data collection is done by finding literature, observation, interview, and documentation. From the results of the research that the image of pleural effusion with RLD projection ( Right Lateral Decubitus ) shows better radiographic picture in assessing the level of pleural effusion with clinical DHF ( Dengue Haemoragic Fever ).

This study aims to find out how to measure exposure dose medical techniques which accepted the patients with a variety of ma and s at the same mas value and the effect of variations in the value of mili ampere and second different with the same mas value to medical exposure dose received by patients. This type of study is an observational descriptive with the approach of the experimental or trial. using gauges medic exposure dose, x-ray multimeter with research indicator mili ampere and second are different but the same mas. From these results it can be concluded the highest medical exposure dose received by patients is the variation of 200 ma and 0.05 s with a dose value of 5.533 mgy / s. this is due to the amount of flow tube (ma). it can be concluded that the greater ma is used, the greater the dose the patient received medical.

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.
