Presumed choroidal metastasis from soft tissue myoepithelial carcinoma

Purpose: To report a case of presumed choroidal metastasis from soft tissue myoepithelial carcinoma and highlight challenges in its diagnosis. Observations: A 52-year-old man was referred with a two-week history of photopsia in his left eye. His background medical history included known soft tissue myoepithelial carcinoma metastatic to his bone, lung, liver and chest wall. A large, raised, yellow choroidal lesion was identified nasal to and abutting the optic disc. This lesion demonstrated growth 1 month after presentation. The patient died with widespread metastatic disease 5 months after initial presentation. Conclusion and importance: Soft tissue myoepithelial carcinoma can rarely metastasise to the choroid and present as a rapidly-growing, yellow, echodense tumour with serous retinal detachment. MRI brain can assist in tumour evaluation and monitoring progression, while immunoperoxidase stains and molecular testing can assist with diagnosis. The condition has an aggressive natural history and poor prognosi

DAMPAK TATA KELOLA PERUSAHAAN TERHADAP PROFITABILITAS DAN NILAI PERUSAHAAN: ANALISIS SIMULASI KEBIJAKAN

The concept of good corporate governance (GCG) has not been fully implemented by most business actors which is reflected in the assessment results of the ASEAN Corporate Governance Scorecard. The study aims to analyze the impact of external and internal factors including the implementation of GCG on the profitability and firm value in the LQ45 index of the Indonesia Stock Exchange. The econometric model is built as a system of simultaneous equations and estimated by using the Two-Stage Least Squares (2SLS) method and the impact simulation analysis policy. The result shows impact of decrease in gross domestic product is greater than increase in inflation. Furthermore if the decrease in gross domestic product or the increase in inflation that is resolved by company policies by improving corporate governance, making efficiency by reducing operational costs, and increasing total assets, have greater impact than the company resolved by improving corporate governance and making efficiency by reducing the cost of goods sold. Keywords: econometric model, external and internal factors, firm value, good corporate governance, profitabilit

Penggunaan Pangsa Pengeluaran Pangan sebagai Indikator Komposit Ketahanan Pangan

Many indicator can use for measuring food security, one of that is food expenditure share. The objective of this research are in order to: (1) account individual food expenditure share and (2) analyze the relation of food expenditure share and food security. The econometrics approach was used to analyze the available data. This analysis is using Susenas data for 1996, 1999, and 2002 and province PDRB data 2002. The result was indicated that food expenditure share is feasible as indicator for food security because had strong relation with some measuring of food security e.g. consumption, food diversivication, and income

Keterkaitan Sektor Ekonomi dan Distribusi Pendapatan di Jawa: Pendekatan Social Accounting Matrix

The objective of this study is to analyze economic sectors linkages, output multipliers, value added multipliers, and household income distribution in Java. The results of this study find that: (1) food, beverages, and tobacco industry sectors, and trade, hotel and restaurant sectors, tend to market oriented, so that less linkages with other sectors in backward to growth, (2) forestry and hunting sectors have small linkages vertically with wood and wood products industry, (3) economic injection of any sectors is in favor of household groups in the urban than household groups in the rural, (4) in general, distribution of the increase household income in Java is tend to divergent. If Indonesian government can reordering position of food, beverages and tobacco industry, and trade, hotel and restaurant sectors, it will increase output of other sectors, and then will reduce unemployment and poverty

Dampak Alokasi Anggaran Pengeluaran Pembangunan terhadap Perekonomian Indonesia: suatu Analisis Simulasi Kebijakan

This study aims (1) to construct Econometric Input-Output Model for Indonesia,which emphasizes the linkage between sectors, and (2) to analyze the impact of budgetallocation policy of development expenditure on Indonesian economy.The model, which construct by combining the advantages of input-output modeland econometric model, is called Model Input-Output Ekonometrika Indonesia. Themodel consists of 112 dynamic simultaneous equations, and it uses secondary data from1980-2000. The equation\u27s parameters are estimated by using the combination of threeestimation methods: (1) Ordinary Least Squares, (2) First Order of Autoregressive, and(3) Second Order of Autoregressive. The model is validated by Gauss-Siedel Methodand it is used for policy simulation analysis of budget development expenditure.The study shows that the impact of budget reallocation of developmentexpenditure on Indonesian economy (final demand, output, income, and sectoralemployment) is better than the budget allocation of development expenditure inRAPBN (National Budgetary Plan) 2002. Plantation sector gave the highestcontribution in supporting the output multiplier and high income. Furthermore, the food,beverages, and tobacco industries gave the highest contribution in creating highemployment multiplier

Estimasi Nilai Ekonomi Air Irigasi Dan Strategi Pemanfaatannya Dalam Penentuan Iuran Irigasi

The study is aimed to valuate irrigation water and to assess its prospect forwater pricing strategy, and implication of optimal cropping pattern on farm\u27s incomeand rice production. Mathematical programming is applied for the valuation. Strategyof water pricing based on the reconciling efficiency and equity concern. Results of thestudy show that shadow price of irrigation water were equal to zero on December–Mayand positive on June–November. Within the positive period, the lowest and highestprices were taken place on June and September respectively. Monthly average of theshadow price was Rp. 40 700/(l/sec), which is equivalent with Rp. 15.75/m3. It isfeasible to apply the shadow price for determining ceiling rate of irrigation watercharges. Potential method of water pricing is combination of per unit area in wet seasonand per crop pricing in dry season. Implementation of optimal cropping pattern as wellas water pricing was potential to improve both farm\u27s income and irrigation efficiency,but disincentive to increase rice production

Factors Affecting Profitability of Construction Company Sub-Sector

The increase is in construction activities is not always good considering that in the construction sub-sectors, the company is a long-term investment, and the payment is following the terms of project completion, causing a decrease in the company's profitability. This study aims to analyze the company's profitability in the construction subsector and the impact of the company's external and internal factors in the construction subsector. This study uses a simulation method with a simultaneous equation model consisting of seven simultaneous equations and six identity equations estimated using the 2SLS method (Two-Stage Least Squares). The Results Showed that if the gross domestic product fell by 4% and the cost of revenue decreased by 5%, it resulted in an increase in return on assets by 12.95% (to 1.93% ROA) and returned on equity equal to 4. 07 (ROE to 27.96%). If inflation rises by 4% and the cost of revenue decreased by 5%, it would increase is the return on assets by 12.79 (ROA to 1.92%) and return on equity by 3:52% (ROE to 27.81%). If inflation rises by 4%, the gross domestic product falls by 4%, and cost of goods costs fall by 5%, the resulting in an increase in return on assets by 9.61% (ROA to 1.87%) and return on equity by 1.96% (ROE to 27.39%).
