The most drought resistant among the five most important cereal crops, and a key dual-use (grain and biomass) crop in regions containing some of the world's most degraded soils, sorghum has inherent climate resilience that is likely to become more important under environmental conditions that are projected by many climate change models. The importance of sorghum might be further elevated by the development of productive genotypes that increase the extent and duration of soil cover beyond those of conventional annual crops, mitigating or even reversing losses of ecological capital through multiple crops from single plantings. Rich genetic and genomic resources have been developed to link Sorghum phenotypic diversity to its molecular basis, and in particular the genus has become a model for dissecting the molecular control of perenniality. Nature has made Sorghum perennial at least twice, and crosses between wild perennials and cultivated sorghums show the feasibility of developing genotypes with varying degrees of investment in perenniality while still providing harvestable food, feed, sugar and/or cellulose. Genetic analysis of progeny from these crosses is revealing the hereditary basis of traits related to ratooning and perenniality and providing diagnostic DNA markers. One perennial Sorghum species has adapted to continents and latitudes far beyond the reach of its progenitors, surviving stresses year after year that are only periodically experienced by conventional (annual) sorghum, and may also harbor novel alleles that may mitigate production challenges in conventional annual sorghums.

This paper aims to provide a critical assesment of Conservatives's and new Labour's social assistance reforms in the U.K. and their differential impacts on low income groups. During the period of 18 years in power, the Conservative governments enforced benefit recipients being capable of work to be out of benefits and to get into work. They employed not only 'carrots' to encourage beneficiaries being capable of work to have full-time work, but also 'sticks' to discourage them to depend on benefits. The reforms under the Conservative governments were closer to the workfare model. The new Labour government has continued to emphasize work regarding social security reform. It has raised 'from welfare to work' as the main reform objective. However, it has not necessarily focused on 'carrots and sticks' in order to get beneficiaries into work. Instead, the new Labour government has put its priority regarding social assistance reform on human capital development in order to develop the capability of beneficiaries for work. Britain under the new Labour government seems to be moving from workfare to activation model. These differentials between the Conservative governments and the new Labour government regarding social assistance reforms bring about the different policy outcomes. Under the Conservative government, social assistance programmes were prone to strengthen the state's control over benefit recipients and to increase stigma to them. Punitive, demeaning, stigmatising programmes of work and unending job search activities harm the bases of self-respect. On the contrary, the activation programmes under the new Labour government has contributed positively to both socially significant participation and autonomy of beneficiaries.

This paper analyzes factors affecting enterprise's financial risk listed on the Vietnam stock market. The panel data of research sample includes 524 non-financial listed enterprises on the Vietnam stock market for a period of eleven years, from 2009 to 2019. The Generalized Least Square (GLS) is employed to address econometric issues and to improve the accuracy of the regression coefficients. In this research, financial risk is measured by the Alexander Bathory model. Debt structure, Solvency, Profitability, Operational ability, Capital structure are independent variables in the study. Firm Size, firm age, growth rate are control variables. The model results show that in order to prevent and limit financial risk for enterprises listed on the Vietnam Stock Market, attention should be paid to variables reflecting Liability structure ratio, Quick Ratio, Return on Assets, Total asset turnover, Accounts receivable turnover, Net assets ratio and Fixed assets ratio. The empirical results show that there are differences in the impact of these factors on the financial risk in state-owned enterprises and non-state enterprises listed on the Vietnam stock market. The findings of this article are useful for business administrators, helping business managers make the right financial decisions to improve the efficiency of financial risk management in enterprises.

Mine drainage from coal mines is mostly acidic, polluted and/or contaminated, even if its quantity has increased substantially during recent days. This causes two kinds of problems arising at mining districts; one is the environmental disruption and the other is insufficient water supply for living, employee's bathing and industrial purposes. In order to mitigate the aforementioned problems, a specific equipment of Korea type for mine drainage purification has been developed and its prototype manufactured, followed by its applicability tests implemented at mine site. The results of the tests indicates that the new equipment developed is much lower than and economical compared to, other existing neutralization facilities at home and abroad in capital investment at installation stage, the consumption of neutralizing chemicals at operation stage and the requirements of installation site. Whangji area where the prototype water treatment equipment is installed has been sustaining a short supply of usable water, especially in dry seasons and supplementing about 40㎥ of water brought from a location farther than 4km in distance to meet water requirements. The prototype water treatment equipment is however considered capable of providing compressor cooling water in sufficient amount from winter season In the future.

The 'Excellent Quality Competitive Enterprises' selection system began with the government's selection and announcement of 'Top 100 Excellent Quality Competitive Enterprises' in 1997 in accordance with Article 6 of the Quality Management and Safety Control of Industrial Products Act and Article 5 (Selection of excellent quality management enterprises, etc.) of the Act's Enforcement Decree. The content of the research and analysis results is summarized as follows: 1. The participation and confidence of enterprises in the differentiation of the assessment system for the excellent quality competitive enterprises selection system is high: from the initial year to the present, 10% of enterprises have participated in the system for over 10 years and since 2000 participating enterprises have been on a steady rise. 2. The distribution of participating enterprises is not limited to any specific region but is spread nationwide, while the participation scale and business types also are being evenly distributed. 3. From the perspective of management performance, as compared with the average of domestic manufacturing businesses or that of U.S. manufacturing businesses, an analysis found that among management results, the excellent quality competitive enterprises achieved far higher sales growth and operating profit rate on sales, however their own capital ratio and debt to equity ratio appeared to be slightly higher.

A national consultative project entitled "corrosion cost survey in China and preventive strategies" was funded by the Chinese Academy of Engineering in 1998. Soon afterwards, an expert group was organized jointly by the Institute of Metal Research, CAS and Chinese Society of Corrosion and Protection. The report on corrosion cost survey in China was published in 2003. According to this report the overall annual corrosion cost in China estimated by the Uhlig Method and Hoar Method at 1997-2001 was found to be 200.7 billion Yuan RMB and 228.8 billion Yuan RMB respectively, which is equivalent to 2% of the gross national product of China. However the total cost of corrosion including the direct and indirect cost was estimated to be more than 500 billion Yuan RMB per year in China. Among them, corrosion cost of infrastructure ranked in first comparing with other sectors. Although corrosion costs in some sectors, such as electric power, petrochemical, oil pipeline and railway in China has reduced in the past years, significant losses are still being encountered in most sectors of industries and cost-effective methods have not always been implemented. Both successful and unsuccessful cases in corrosion control and corrosion management were collected. As the investment in capital construction continues increasing rapidly in China, the maintenance and life extension of the infrastructures will become a big issue. The preventive strategies have been suggested

The purpose of this study was to explore the influencing factors of consumption behavior of healthy functional foods including vitamin/mineral products for overweight and obese Koreans. Overweight and obese Koreans were selected based on the body mass index(BMI) from the KNHANES that was collected in 2007. Probit estimation model was used to find the influencing factors such as age, gender, job, education, income, nutrition education, and cultural capital(parents' education) on consuming the healthy functional foods. Overweight consumers were found to consume vitamin/mineral products and healthy functional foods at 17.5% and 22.7%, respectively. Obese consumers were found to consume vitamin/mineral products and healthy functional foods at 18.2% and 22.8%, respectively. In addition, self decision was found to be a significant factor to consume both products in both groups. Nutritional education and job were significant factors to consume vitamin/mineral products in overweight consumers, while mother's education and job(service) were significant factors in obese consumers. Weight control for body shape, gender, age, and income were significant factors to consume healthy functional foods in overweight consumers, while nutrition label and perceived health status were significant for obese consumers. Therefore, providing consumer information on functional foods might be useful for consumers to consider the healthy functional foods as an available option to purchase. Various influencing factors between two groups might be concerned to develop different strategies for promoting the healthy functional foods consumption including vitamin/mineral products.

This paper examines the effect of the global financial crisis on corporate investment in Korea. Specifically, the crisis was considered to have possibly constrained firm-level investment as the negative shock to the credit supply dramatically unfolded. As Duchin et al. (2010) demonstrated, if a negative supply-side shock is evident during a crisis period, larger cash holdings before the crisis will lead to fewer constraints to corporate investment, or vice versa. In order to investigate the supply-side effect of the crisis, we use firm-level financial data, including firms listed on the Korean stock market as well as small and medium-sized enterprises. We find that corporate investment declined significantly after the crisis, even if we control for factors associated with the demand side, such as contemporaneous capital productivity and cash flow. More importantly, the decline is positively and significantly related to cash holdings before the crisis, implying the negative effect of a credit supply shock. Small and medium enterprises experienced relatively sharp investment declines compared to those of larger firms, and the relationship between pre-crisis cash amounts and the degree of investment decline is greater than that in large firms. Additionally, we examine whether the negative effect persists up to the present, finding evidence that the cash-investment relationship continues in small and medium-sized enterprises.

Multiperiod portfolio selection problem attracts more and more attentions because it is in accordance with the practical investment decision-making problem. However, the existing literature on this field is almost undertaken by regarding security returns as random variables in the framework of probability theory. Different from these works, we assume that security returns are uncertain variables which may be given by the experts, and take absolute deviation as a risk measure in the framework of uncertainty theory. In this paper, a new multiperiod mean absolute deviation uncertain portfolio selection models is presented by taking transaction costs, borrowing constraints and threshold constraints into account, which an optimal investment policy can be generated to help investors not only achieve an optimal return, but also have a good risk control. Threshold constraints limit the amount of capital to be invested in each stock and prevent very small investments in any stock. Based on uncertain theories, the model is converted to a dynamic optimization problem. Because of the transaction costs, the model is a dynamic optimization problem with path dependence. To solve the new model in general cases, the forward dynamic programming method is presented. In addition, a numerical example is also presented to illustrate the modeling idea and the effectiveness of the designed algorithm.
