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.

Frequency Criterion of Robust Modality for the Class of Linear Systems with Time-delays

Ilya Aleksandrovich Rybin,Vasiliy Grigorievich Rubanov 제어·로봇·시스템학회 2021 International Journal of Control, Automation, and Vol.19 No.2

A class of linear systems described by rational transfer functions with interval parameters and fixed timedelay values is considered in this study. The ranges of variation of the interval parameters depends on the total range of perturbations. A sufficient frequency criterion for robust modality is formulated. This criterion is determined by the inclusion of all the roots of a system characteristic quasi-polynomial to the region located to the left of the given position of the vertical boundary. The advantage of the developed criterion in comparison with similar ones is the possibility of refusing to analyze the set of characteristic quasi-polynomials of the system, as well as refusing to analyze the nominal system. This provides by constructioning and studying only two hodographs. In special cases, the developed criterion coincides with the known frequency criteria for system analysis.

( Ilyas Nazarov ),( Issa Nazarov ) 대한간학회 2020 춘·추계 학술대회 (KASL) Vol.2020 No.1

Aims: This retrospective study aimed to compare the efficacy of and tolerance to two center-related conventional transarterial chemoembolization (TACE) strategies in the management of unresectable hepatocellular carcinoma (HCC). Methods: All HCC patients in whom TACE was initiated in the two centers from July 2008 to June 2016 were included. The TACE strategy performed in center 1 was “on demand” with selective injections of idarubicin, whereas the TACE strategy in center 2 was based “on scheduled” non-selective injections of epirubicin. Toxicity was evaluated using the National Cancer Institute Common Terminology Criteria for Adverse Events. Results: One hundred and fifty HCC patients were included. Median time to treatment failure was significantly higher in center 1, 13.1 months vs. 7.9 months in center 2 (hazard ratio, 2.32; P<10-3 in multivariate analysis). Median overall survival was 21.1 months in center 1 vs. 18.4 months in center 2 (P=NS). The proportion of grade ≥ 3 adverse events and mean hospitalisation duration for the overall TACE treatment were significantly greater in center 2 than in center 1: 56% vs. 32% (P<0.01) and 14.2 ± 7.2 days vs. 10.3 ± 7.0 days (P<0.01), respectively. Conclusions: Our results failed to show any significant survival differences between two center-related TACE strategies but showed a significantly smaller proportion of grade ≥ 3 adverse events and shorter hospitalisation for the overall treatment when the “on-demand” strategy was used.

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.

Bioremoval of heavy metals from recycling industry electronic waste by a consortium of moderate thermophiles: process development and optimization

Ilyas, Sadia,Lee, Jae-chun,Kim, Byung-su Elsevier 2014 Journal of Cleaner Production Vol.70 No.-

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.

Liquid–liquid separation of copper and nickel ammine complexes using phenolic oxime mixture with tributyl phosphate

Ilyas Sadia,Srivastava Rajiv Ranjan,Jin Suhyeon,Kim Hyunjung 한국자원공학회 2023 Geosystem engineering Vol.26 No.2

In the present study, a complete separation of copper over nickel has been studied from an ammoniacal leach liquor of nickel laterite ore generated via the Caron process. For this purpose, a phenolic oxime (LIX 84-IC) used as the extractant molecule was mixed with tributyl phosphate (TBP) to inhibit the co-extraction of nickel with copper loading into the organic phase. The antagonistic effect of TBP was confirmed by the distribution coefficients to be Dmix << DLIX 84-IC + DTBP and negative values of ΔD. The highest separation (βCu/Ni) of >1329 was yielded using the molar ratio of organic mixture at LIX 84-IC:TBP = 0.4:0.6 at an organic-to-aqueous phase ratio of 1. The thermodynamic properties of copper extraction exhibited an endothermic nature with ΔH° value of 5.4 kJ∙mol−1, indicating the formation of inner-sphere coordination between metal ions and the organic mixture. Further, the stripping of copper from the loaded organic phase was quantitatively achieved by contacting with 1.0 mol∙L−1 H2SO4 solution at the unit phase ratio.

The Concept of Fundamental Breach under the CISG: Is There a Need for Redraft?

Ilyas GOLCUKLU(골추클루 일리아스) 한국무역상무학회 2023 貿易商務硏究 Vol.98 No.-

국제물품매매계약에 관한 유엔협약(비엔나, 1980(이하”CISG”)은 국제물품매매계약에 널리 인정되고 사용되었다. CISG가 규정한 가장 중요한 개념 중 하나는 “중대한 계약위반”의 원칙이다. 이 개념을 규정하는 제25조는 중대한 계약위반에 대한 만족스러운 정의를 제공하기 위한 충분한 정보를 제공하지 않는다. 다른 국제사법 규정과 마찬가지로 CISG는 국제 무역에서 통일성과 예측 가능성을 제공하는 것을 목표로 한다. 최근 여러 관할권의 사례를 비교적 관점에서의 분석을 통해 본 연구는 “중대한 계약위반”의 개념 자체가 보편적으로 수용되고 신뢰할 수 있는 정의의 부족으로 인한 근본적인 문제를 가지고 있으며 제25조를 재작성하는 것이 급진적이면서도 효율적인 해결책이 될 수 있다고 단언한다. UnitedNations Convention on Contracts for the International Sale ofGoods (Vienna, 1980) (“CISG”) has been widely accepted and used for international sale contracts. One of the most important notions created by the CISG is the principle of “fundamental breach”. Article 25 stipulating this notion does not provide sufficient information in order to provide a satisfactory definition of fundamental breach. As other private international lawconventions, the CISG aims to provide uniformity and foreseeability in international trade. By analyzing some prominent cases fromvarious jurisdictions, this study asserts that the concept of “fundamental breach” has fundamental issues in itself due to lack of a universally accepted and reliable definition and redrafting the article 25 might be a radical yet efficient solution.

Ilyas Masudin,Yudha Firmansyah,Dana Marsetiya Utama,Dian Palupi Restuputri,Evan Lau 대한산업공학회 2021 Industrial Engineeering & Management Systems Vol.20 No.3

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
