Zellner, Kmenta, Dreze (1966) and later Hedges (1969) showed that consistent estimates of the parameters of Cobb-Douglas or CES production functions can be obtained by the single equation estimation methods if the models incorporate the assumption that firms maximize the mathematical expectation of profits. This note demonstrates that the results of the above-cited works can be extended to a class of VES production function models.

Green Marketing, a response to the serious environment problems of the 21st century, is an important point for trends in both art and fashion. It is a strategy for reminding consumers of the threatening environment problems and to recognize that everyone must take responsibility for these problems. Green marketing is a concept that is the point at issue and social reform movement. The purpose of this study was to find examples of Green Marketing in fashion and classify them into four groups. The results of this study were as follows. First, the terms related to green marketing as related to fashion can be categorized into four areas: 1. Eco-friendly product marketing: product merchandising that usually uses organic materials and green manufacturing processes. 2. Green-communication marketing: PR strategies that use green slogans through deep impression advertising or special promotional events relating reducing, reusing and recycling, etc., with the brand's name. 3. Green environmental-marketing: marketing strategies that is an enlightenment campaign for environmental preservation and sustainable fashion design such as reusing, recycling, and reducing. 4. Cause-related marketing: marketing plans that return profits to society and that take an active part in the causes of the community. It was expected that these types of green marketing strategies would yield positive effects in enhancing brand value and consumer confidence as well as increasing profits.

In recent years, anti-PID (Potential Induced Degradation) technologies have been studied and developed at various stages throughout the solar value chain from solar cells to systems in an effort to enhance long-term reliability of the photovoltaics (PV) system. Such technologies and applications must bring in profits economically for both manufacturers of solar cell/module and investors of PV systems, simultaneously for the development of the PV industry. In this study two selected anti-PID technologies, ES (modification of emitter structure) and ARC (modification of anti-reflective coating) were compared based on the economic features of both a cell maker with 60MW production capacity and an investor of 1MW PV power plant. As a result of this study, it is shown that ARC anti-PID technology can ensure more profits over ES technology for both the cell manufacturer and the investor of PV power plant.

The study aims to estimate the effect of current ratio (CR), current liability to inventory (CLI), total asset turnover (TAT), net profit margin (NPM), sales growth (SG), and company size (FS) on profit growth (PG). The research population was 18 companies in the Food and Beverage (F&B) sector listed on the Indonesia Stock Exchange (IDX) from 2014-2018. The data estimation method uses the common effect panel data regression model. The empirical findings show that the CR and CLI ratios have a negative effect on PG, while the TAT, NPM, and SG ratios have a positive effect. Company size is a factor that does not affect the growth of company profits. The results of the study imply that an increase in company profits can be achieved if the company operates efficiently and with low liquidity to encourage higher sales growth. The limitations of the research are as follows: first, this research considers only one type of industry, hence the results of this study would not be the same if applied to another type of industry. Second, the author observes profit growth by using the company's financial ratios and size and ignores other factors that may affect profit growth, for example, the number of employees, total net sales, and market capitalization.

This research is to analyze ethics in fashion design for more valuable and sustainable human life against the increasing alienation of the human being, the global ecological crisis resulted from contemporary consumption society. I expect that it can be helpful to plan ethical fashion design practice more effectively. For this, the documentary study and practical case study have been executed. The results are as follows. The ethics in design can be defined as the responsibility to reform the social, environmental problem of consumptive design, to sustain together without human alienation, environment disruption and to do social good for total human being ultimately. The ethical design practice means to suggest solutions to problems of human rights and environment and to act willingly. Based on this, ethical fashion design appeared as responsible design solution which has two directions. One is the fashion design for coexistence and sharing, including the design for all which considers even underprivileged minority, the design to promote public issues as well as to donate some profits. The other is the eco fashion design for sustainable environment, including eco-friendly design which is reductive and slow in whole design process, the design to inform the seriousness of environmental crisis as well as to donate some profits. The last one of the most important ethical responsibility as fashion designer is to abide by vocational ethics, that is, the prohibition of design piracy.

The standard of agricultural mechanization is one of the important indicators for measuring the realized degrees of agricultural modernization in some regions. The Pearl river delta is most fertile, and thereby reputed as a land of fish and rice in the province. Studying the proceedings, profits and experiences of agricultural mechanization in the region obviously possesses the generally guiding significance for Guangdong to realize agricultural modernization by the year 2010. this paper involves these fields such as duainage, irrigation, harrowing, harvesting, transportation, processing and etc, in the Pearl River Delta, Results show as follows: (1) 80% work load in main production links has been mechanized ; (2) changed took place in traditionally agricultural production means and ways so took place in traditional agricultural production means and ways so that individual farmer in this region became commercial producer and then march toward commodity production of moderniza ion with high yields, good guality and high profits ; (3) further taping production potential to improve land output and labour productivity. Results also show that the degrees of agricultural mechanization in the Pearl River Delta are closely related to government' spolices, finance, moderate land scale management, rural industrialization and machine utility as well as talent training, shortage of which will surely; affect the proceeding of agricultural mechanization. Therefore, government must be urged to guarantee it by preferential policies and financial loan so as to greatly run rural industry, to create conditions for land scale management, to set up the socialized service system of agricultural mechanization, to actively train scientific talents and to introduce advanced equipments and technology from aborad in order to quicken the progress of agricultural mechanization in this regions.

Purpose - The goal of this research is to examine the influence of Quick Response on the supply chain performance. Furthermore, this study investigates the potential of Quick Response to be a more advanced form of supply chain collaboration program with extensive information sharing activities. Research design, data, and methodology - The mathematical model is developed to represent the two stage supply chain system with a single manufacturer and one retailer. In the numerical study with the proposed mathematical models, three supply chain systems including the traditional system, Quick Response, and the fully shared information system are compared in terms of their profits. Results - The numerical analysis shows both manufacturer and retailer obtain greater profits under Quick Response than in the traditional system. While the fully shared information outperforms Quick Response as well as the traditional system, it results in lower manufacturer's profit compared with Quick Response. Conclusions - According to the numerical examples, Quick Response is the effective supply chain collaboration program that is beneficial to every supply chain member. The fully shared information system, as a more advanced form of collaboration than Quick Response can bring more benefits to the whole supply chain system, but it is necessary to prepare the proper incentive program that enables every member to share its benefits equally.
