In general, industrial production involves large amounts of harmful by-product, causing serious pollution and ecological risk. Eco-efficiency, which indicates how efficient the economic activity is by considering both the environmental risks and economic performance, is a new concept for economic sustainability analysis and quantitative ecological risk analysis. Data envelopment analysis (DEA) has been widely used to examine eco-efficiency in recent years. Whereas traditional DEA models such as CCR and BCC model neglect undesirable outputs, this paper adopts a stochastic undesirable-output DEA model to measure the eco-efficiency of each province of China and Korea. The results indicate that whereas the eco-efficiency of the eastern region was the highest, that of the western region was the lowest. The reason may come from the negative external dis-economies of environment. And thus the governmental efforts for outreach on the underdeveloped regions should be promoted.

This study establishes management plan for water quantity and quality using PCSWMM and alternative evaluation index (AEI). PCSWMM can consider combined sewer overflows (CSOs) and simulate not only the flowrate but aslo the pollutant of BOD, SS, TN and TP for the effectiveness analysis of alternatives. Indicators of AEI are selected using sustainability evaluation concept, driver-pressure-state-impact-response (DPSIR) model and calculated by weighted summation method. These were applied for the Mokgancheon watershed which has many combined sewers. This result will be effective to the integrated watershed management for sustainability.

Among the many methods to make sustainable garments, convertible garments have the potential to change style and function that allow consumers to keep and use garments longer with the possibility of enhancing sustainability. This research analyzes consumer preferences in changeable design options for convertible dresses and the consumers' influence on environmentally responsible apparel consumption (ERC) behaviors on their preferences regarding changeable design options of dresses, which are popular items. An online survey collected data from a convenient sample of 321 female college students from four universities in the United States. Data were analyzed using IBM SPSS through descriptive analysis, cluster analysis, and independent samples t-test. There were significant differences between high and low ERC groups in design preferences that considered important aspects of purchasing, using convertible dresses, and purchase intentions. Detailed differences among sub-groups were analyzed. Designers are encouraged to make tying/folding/wrapping dresses with changes of size/fit, dress length, or color/pattern. The results are beneficial for apparel designers when developing convertible dresses with the guidance of consumers' design preferences and differences according to ERC levels.

This paper's objective is to draw a decision guideline to continue research and development (R&D) investments in biotech start-ups facing the "Valley of Death" syndrome - a long negative profit period during a financial crisis. The data include financial indices as Net income, Revenues, Total stockholders' equity, Cash & equivalents, and R&D expenses of 18 major biotech companies (nine in negative profit and nine positive, in FY2008) and 15 major pharmaceutical corporations as benchmarks both in FY2008 and in FY2016 derived from the US SEC Database, EDGAR. A first methodology dealing with real options analysis assumes Total stockholders' equity as a growth option. And a second methodology, Bayesian Markov chain Monte Carlo (MCMC) analysis, is applied to test the probability relationship between the Total stockholders' equity and the R&D expenses in these three groups. This study confirms that Total stockholders' equity can play the role of a call option to support continuing R&D investments even in negative profits.

Starting from the capabilities approach, this work develops the concept of Sustainable Wellbeing, which highlights the importance of incorporating temporal sustainability in the analysis of wellbeing, with intergenerational justice. For its measurement, 12 dimensions are identified and defined, based on the philosophical approach of Central Capabilities of Martha Nussbaum. The measurement is applied to 18 Latin American countries, with 116 indicators and using a multiple correspondence analysis (MCA). The results show the viability of operationalizing the capabilities approach and its potential to support the formulation of associated policies.

The application of Photovoltaic (PV) power in the building sector, is expanding as part of the ongoing energy transition into renewables. The article addresses the question of sustainability of energy generated from PVs through an environmental assessment of a building-integrated PV system (BIPV) connected to the grid through net metering. Employing retrospective life cycle analysis (LCA), with the CCaLC2 software and ecoinvent data, the article shows that the carrying structure and other balance of system (BOS) components are responsible for a three times higher energy payback time than the literature average. However, total environmental impact can be lowered through reuse or reinstallation of PVs on the same building structure after the 30-year interval. Further ways to improve environmental efficiency include identifying the most polluting materials for each LCA parameter. The results of this study are of interest to researchers and producers of PVs and organizations investing and promoting decentralized power production through PVs.

Purpose - The purpose of this study is to empirically investigate the degree of performance inconsistency among the Environmental, Social and Governance ratings. Design/methodology/approach - This study performs regression analysis using the widely used ESG ratings published by the Korea Institute of Corporate Governance and Sustainability. Findings - The results show that firms often do not show consistent performance across the Environmental, Social and Governance aspects, with excellent performance on one aspect but mediocre or poor performance on another. The paper also finds some degree of firm-level persistence in such performance inconsistency, suggesting that the traits of the firm and the industry the firm belongs to might influence whether a firm shows inconsistent performance across the three aspects. Research implications or Originality - This paper highlights the need for researchers and practitioners to understand the underlying behavior of the individual E, S and G ratings, instead of taking them as given, in order to properly design their analyses.

Business environment is shifting from industrial economy to knowledge based economy. Enterprises go through numerous trials for successful management in changing environment. Along with trial tests, research area has been growing simultaneously. Unlike initial research which focused on basic concepts such as: form of business model and success points. Current research emphasizes on actualization of business that enterprises plan, which brought academic research with perplex form of knowledge structure. On the other hand, there is limitation in understanding business model systematically due to preceding research primarily centered on analyzing definition and case study. In order to analyze knowledge structure, this study utilized social network analysis based on "relationship". For the analysis, 13,412 keywords were extracted from 36years worth of article or research related to business model stored in SCOPUS database. From the analysis, it was shown core research subject was INNOVATION and the number of co-authors has increased due to the academic diversity. Business model research is divided into five sub-categories (E-commerce, SMEs, sustainability, open-source, and e-book). Through cognitive map analysis on each of research characteristics of sub-category, it has shown that E-commerce, SMEs, sustainability, and open-source are core categories.

Purpose - This study aims to exploratorily analyze relationship among pressure on business failure, social safety net perception, and entrepreneurial intention targeting potential business founders - pre-entrepreneurs and re-entrepreneurs. Research design, data, and methodology - Out of 450 collected surveys, 386 were used for analysis. Among these, 216 were from pre-entrepreneurs and 170 were from re-entrepreneurs. Frequency analysis, reliability and validity analysis, and regression analysis were performed. Results - In analysis of pre-entrepreneur and re-entrepreneur's pressure on business failure and social safety net perception, objective environment perception - a subfactor of social safety net perception - had statistically significant difference between the two potential entrepreneur groups. Conclusions - We categorized potential entrepreneurs into pre-entrepreneurs and re-entrepreneurs. Also, the current study suggests importance of social safety net to vitalize food service business startup by validifying its mediating effect between pressure on business failure and attitude towards restaurant business establishment. This research also established groundwork for future studies on ways to improve entrepreneurial intention or startup business sustainability by deducing social safety net perception difference between pre-entrepreneurs and re-entrepreneurs. This study was able to analyze relationship between those two groups in terms of entrepreneurial intention and startup business sustainability.

This study examines the correlation between the characteristics of sustainable slow design, The outcome derived from the pro-environmental consciousness in fashion design, and the trends of modern fashion design. The conclusion of this study is as follows. First, slow design for sustainability shows an environmental consciousness and stresses the ethical aspects of fashion design that take into account the wellbeing and sustainable development of human society. It also focuses on the continuos present in which the consistent pace of life endures, rather than pursuing speedy changes of fashion by titillating desire. Second, the five characteristics of slow design have been extracted from the analysis of the examples of fashion industry and other fashion-related areas. They are sustainability, recyclibility, handicraft, naturalness, and simplicity. Third, these characteristics of slow design have much to do with modern fashion genres. For instance, classical style fashions such as Chanel suit and Burberry coat have the same qualities of sustainability, while at the same time the Vintage fashion, which reinterprets the fashions from bygone eras in modern style, has the tendency of recyclibility, and the Hippie style, a resurrection of hand-touch spirit that emerged as a secondhand style expressionism resisting uniform mass production, has not only the quality of handicraft but also recyclibility.
