Purpose: This study discusses the creative industry phenomenon which has different business characteristics both from resources and production processes to distribution. The study intends to analyze the effect of entrepreneurial orientation and market orientation on business performance by using absorptive capacity as a mediator. Research design, data, and methodology: Using the quantitative method, data were collected from 97 respondents, who are managers or owners of creative industry businesses in Makassar City, South Sulawesi, Indonesia. Data analyzed used Partial Least Square - Structural Equation Model. Results: The results of this study reveal that entrepreneurial orientation has no significant effect on business performance and has indirectly a trough absorptive capacity. Market orientation has a significant effect on business performance and indirectly through absorptive capacity. Another result is that absorptive capacity has a significant effect on business performance. Conclusions: When absorptive capability stresses the assimilation and exploitation of knowledge and market intelligence that has been learned to boost business performance improvements, market orientation and entrepreneurial orientation offer knowledge and experience to business processes including the creation of value distribution in the creative industries.

The Aim of the current work is to develop an environmentally friendly process for the removal of heavy metals (Cu, Zn, Ni, Cd, Al, Cr, Pb) from recycling industry electronic waste with a consortium of Sulfobacillus thermosulfidooxidans and Thermoplasma acidophilum. The performances of commercial S-0 powder and biogenic S-0 sludge as substrates for the bio-removal of heavy metals were compared. Empirical models for the bioleaching process based on a statistical analysis were developed to evaluate the individual and combined effects of critical variables including S-0 dosage, particle size, pulp density and bacterial feed formulation (inoculum size and inoculation style) in shaken flasks while specifying the effective variable ranges. Upscale feasibility experiments in a stirred tank reactor demonstrated a maximum metal bio-removal efficiency (92%) at a 1% dosage of biogenic S-0 sludge and 2% dosage of commercial S-0 powder (82%), given a 15% pulp density and 150 mu m particle size with an intermittent low-concentration addition of inoculum (1 x 10(6) cells/mL). Biogenic S-0 sludge showed a higher degree of S-0 oxidation (95%) in a shorter time period (12 days) compared to commercial S powder (82% in 24 days), thereby reducing the process cost. Risk assessments of discarded electronic wastes before and after bioremediation by the toxicity characteristic leaching procedure (TCLP), waste extraction test (WET), synthetic precipitation test (SPLP) and total threshold limit concentration (TTLC) indicated that the leaching/toxicity of bio-remediated residue was well within the regulatory limits.

This study aims to control several decision variables, namely the frequency of ordering raw materials (m), the frequency of delivery of finished products (n), and the production cycle time (T) to maximize the total profit per unit time of the inventory-production integration system. The method used for this study is the optimization of mathematical models with non-linear equations. To optimize the model used MATLAB software by utilizing a genetic algorithm (GA) tool. The output of this research is the proposed policy in managing inventory-production. The results of numerical calculations show that the research model policy provides a better total profit than the company’s policies. This research develops the integrated inventory-production (IIP) model considering imperfect quality (products return). Model performance is measured based on the total profit of the inventory-production integration system
Fuzzy Regression Analysis using Trapezoidal Fuzzy Numbers
Ilyas Idrisovich Ismagilov,Ghena Alsaied 대한산업공학회 2020 Industrial Engineeering & Management Systems Vol.19 No.4
As a widely used method, regression analysis plays an increasingly important role in creating statistical models and making forecasts in the field of economics and finance. The use of traditional regression for modeling socio-economic processes is not sufficiently substantiated in some situations. Currently, a new direction is being actively developed, associated with fuzzy regression analysis and its application as an alternative to classical methods for modeling economic phenomena. Fuzzy regression methods are based on the theory of fuzzy sets. A number of methods and their modifications are proposed for constructing fuzzy regression models, but most of them use triangular fuzzy symmetric numbers. In this paper, we propose a new method for constructing linear fuzzy regression using trapezoidal fuzzy numbers. The method is based on dividing the sample using a regression model which is estimated by using the ordinary least squares. Two fuzzy regressions using triangular numbers are estimated from the formed samples, on the basis of which a fuzzy model with trapezoidal fuzzy numbers is constructed. Basing on the proposed method, a linear fuzzy model of the gross regional product as an indicator of the economic development of the Republic of Tatarstan of Russia is constructed depending on a number of factors. A comparative assessment of the quality of fuzzy regression models using triangular and trapezoidal numbers was performed.

Solar photovoltaic systems have evolved as a prominent renewable source of energy owing to its eco-friendly nature, long lifetime, and low maintenance requirement. However, its conversion efficiency is very low. Different maximum power point tracking (MPPT) techniques have been used to extract maximum power from the photovoltaic system. In this study, the perturb and observe (P&O) MPPT algorithm, which is practically implemented on an Arduino Uno board and simulated in Matlab/Simulink under the same environmental conditions, is used to track the maximum power. Different parameters of a Simulink-based PV module and a practical photovoltaic module are obtained and compared. The main advantages of the P&O MPPT algorithm are its low cost and easy implementation. However, it may fail to track the maximum operating point under varying environmental conditions.
A NOTE ON THE REMOVAL OF PHYTATE IN SOYBEAN MEAL USING Aspergillus usami
Ilyas, A.,Hirabayasi, M.,Matsui, T.,Yano, H.,Yano, F.,Kikishima, T.,Takebe, M.,Hayakawa, K. Asian Australasian Association of Animal Productio 1995 Animal Bioscience Vol.8 No.2
Soybean meal was fermented by Aspergillus usami in order to reduce phytate content. Aflatoxin B1 was not detected in the fermented soybean meal. The contents of crude protein, crude fiber, ether extract and crude ash were slightly increased following fermentation with a concomitant reduction in nitrogen free extract. Though the fermentation partly degraded proteins in the soybean meal, there was small difference in amino acid composition between the soybean meal and the fermented soybean meal. The results showed that the fermentation did not affect nutritional value of protein in soybean meal. Approximately 55% of phosphorus extracted by trichloroacetic acid was inositol hexaphosphate (phytate) in the soybean meal. The content of inositol tetra to hexaphosphates was not detected in the fermented soybean meal. These results indicated that the fermentation almost completely eliminated phytate in soybean meal. Phytase activity was not detected in the unfermented soybean meal. However, the enzyme activity in the fermented soybean meal was 167.7 U/g. When the fermented soybean meal in supplemented in formula feeds, phytase in the fermented soybean meal might partly degrade the phytate in other ingredients in the digestive tract. The fermented soybean meal is possibly used as a phytate-free protein source of feed, which contains high available phosphorus.
