The article examines the attempts made at economic revitalisation of Ljubljana's inner city and the consequences or "collateral damage" of this process. A lot of attention is given to the wider socio-cultural context, in which art istic practices are embedded in the city, and to the Slovenian population's perception of such practices. Artistic groups and their practices are in this sense used as part of an 'interim development' strategy, i.e. temporary guests(non-statutory tenants) are warmly welcomed because their (sub) cultural capital happens to cultivate the area, making it "cool" and attractive, but when the value of the area's real estate begins to rise their low-income status does not grant them any tenant protection. Regardless of the social role they played in revitalising the city, these groups are therefore gradually ousted from neighbourhoods, which quite ironically are often advertised in the real estate market as the city's "Bohemian" or "cultural" quarters. This makes us aware of the lack of unique alternative or informal spaces, venues for alternative art movements and practices in the cities. These issues are presented on the cases of the alternative spaces of Metelkova and the Rog Factory, both located in Ljubljana'sinnercity.

We have hypothesized that nuclear risk is significantly inversely related to the distance from residences to nuclear power plants and that the level of life satisfaction of residents therefore increases with the distance. We empirically explore the relationship between Ulsan citizens' life satisfaction levels and the distance between their residences and the Kori and Wolsong nuclear power plants (NPP) based on the life satisfaction approach (LSA). The dataset we used covers only Ulsan citizens from the biennial Ulsan Statistics on Citizen's Living Condition and Consciousness of 2014 and 2016. Controlling for micro-variables such as education, work satisfaction, gender, marital status, and expenditures, we found a statistically significant relationship between life satisfaction and the distance between the residences and the nuclear power plants. Nuclear negative externalities including (i) health and environmental impact, (ii) radioactive waste disposal, and (iii) the effect of severe accidents can be quantified in terms of LS units and monetary units. We were able to calculate the monetary value of NPP externalities at $277 per kilometer of distance for Kori and $280 per kilometer of distance for Wolsong at constant 2015 prices. These estimates are quite different from the traditional estimates made with the contingent valuation method, whereas they are similar to the findings of LSA studies abroad. Hence, the need to adopt the LSA in South Korea and policy implications are demonstrated.

Korea is facing great threat from other countries as a major global sourcing site for textile and apparel products. The threat has been augmented by changes in external environment such as advents of Trading Blocs and Free Trade Area(FTA) as well as internal environment such as hikes in labor cost and lack of flexibility in accommodating international buyers' needs. This study analyzed international buyers' sourcing activities in Korea for the purpose of developing strategies to enhance competitiveness of the Korean textile and apparel industries in the global market. The data used in this study were gathered by surveying 52 non-Korean textile and apparel product buyers with cooperation of the Korea Federation of Textile Industries (KOFOTI). The data were analyzed by mean, frequency, Pearson correlation coefficient, and ｘ$^2$ analysis. The results indicated that Korea is still attractive to many international buyers especially to those who have been engaged in global sourcing for longer periods of time with bigger purchasing budgets. However, in order to expand and solidify their customer bases, Korean companies should focus more on developing competitively priced value added products a step ahead of their foreign competitors, diversifying their marketing channels including internet.

The study investigates the existence of an optimal level of cash and the firm characteristics influencing the decision to hold cash, and the adjusting speed of the cash holdings to the target level. It highlights the heterogeneity of cash adjustment speed in the Vietnam market. The research employs the 417 samples of Vietnamese non - financial listed firms in the period of 2010 to 2019. The study uses the Pool OLS model, Fixed effect model (FEM), Random effect model (REM), and GMM model. According to the research findings, there is an optimal amount of cash at which the firm's value is maximized in Vietnamese listed firms, and the majority of the firms in the sample retain cash over the target level. Furthermore, the study demonstrates that firms actively modify their cash holdings to the optimal level with an adjustment speed of less than one owing to adjustment cost constraints. This speed varies between groupings of enterprises with different characteristics, underlining the heterogeneity of the adjustment speed even more. Small deviation firms adjust more rapidly than large deviation firms. Large free cash flow (FCF) firms adjust more readily than small FCF firms, and fiscal deficit firms modify more rapidly than firms with a financial surplus.

During the 1990s the workplace has grown more complex and business competition has increased world-wide. All organizations, whether for-profit or non-profit have been forced to respond to market changes. More advanced information and technology, greater product diversity, shorter product life cycles, increased quality requirements, more regulation oversight, decreasing productivity, more competitors, and increasing overhead costs have motivated organizations to focus on ways to deliver products cheaper, better, and faster. Many organizations are searching for ways to reduce costs through downsizing, reengineering business processes, implementing quality management, outsourcing, and improving cost management. Support departments that provide services internal to an organization such as human resources, legal, and environmental, safety, and health (ES&H) are often the first organization targeted for cost reduction and cost control initiatives because these functions are part of a rapidly increasing overhead cost. Recently, ES&H functions are incresingly being integrated into the business of business to contribute value to organization beyond mere compliance with ES&H regulations. The discussions and development of the ISO compatible Environmental Management Standards or Occupational Safety and Health Management Standards is another impetus to integrate ES&H function into the business of business. Thus, ES&H professional need new skills to analyze the cost of their function and communicate the value of the products and services they provide. In recent years, the need for and the importance developing cost management and business skills by ES&H professionals have been emphasized in the literature. Communicating with decision makers in terms of cost and value to the organization, and by using business language and business arguments is the first step toward effectively integrating ES&H activities into the business of business. Activity-based costing (ABC) is a cost management method that measures the cost of a product or service based on the actual use of resources by activities, and based on the actual amount of activities used to produce a product or service. ABC is recommended as a tool for managers of ES&H organizations to determine the cost of developing and providing ES&H products within a for-profit firm or non-profit agency. This paper discusses the trend of integration of ES&H functions into the mainstream of business activities within an organization. The general principles of treditional cost accounting are presented as a bases for understandging why and how ABC will provide more accurate estimates of cost. The principles and concepts of ABS are presented as a tool for determining more accurately the true cost of ES&H products and services.

The Korean government has been trying to conserve a marine ecosystem that has been shifting due to climate change. As part of this effort, the government designated seventy-seven marine species that have been disappearing and deserve to be protected as endangered managing them specially. To generate basic data to guide policy for these endangered species, their value must be measured. OOf the species declared endangered, coral is particularly threatened by climate change, and its management is important. Accordingly, understanding the potential value of reefs, can be an effective way of proving the benefits of continuous management to decision makers and the general public alike. To this end, we have applied the contingent valuation method (CVM), an economic technique of for valuing a environmental and non-market goods such as a coral reef. A national face-to-face survey of 1,000 randomly selected households was conducted in order to determine the public's willingness to pay (WTP) for conserving coral reefs. A one-and-one-half-bound (OOHB) model was adopted to interpret WTP responses, and a spike model was employed to deal with zero WTP responses. The results show that the conservation value of a coral reef can be estimated at 3,016 won per household per year, statistically significant at the 1 % level. Expanding values to the national population gives an annual value of 58.9 billion won. We can conclude that the public is willing to pay a significant amount to conserve coral reefs.

This paper attempts to quantitatively assess the conservation value of Ellobium chinense (EC), which belongs to the endangered marine species designated by Ministry of Oceans and Fisheries. To this end, we apply the contingent valuation (CV) method, an economic technique of valuing a non-market goods such as EC. A national survey of randomly selected 1,000 households was administered in order to derive the public's willingness to pay (WTP) for conserving EC. One-and-one-half-bound model was adopted to elicit the WTP responses and a spike model was employed to deal with the zero WTP responses. The results show that the conservation value of EC is estimated to be 2,346 won per household per year that is statistically significant at the 1% level. Expanding the value to the national population gives us an annual value of 43.8 billion won. We can judge that the Korean people are willing to pay a significant amount to conserve EC.

The aim of this study was to develop sample preparation method and evaluate the exact cholesterol content in egg and egg powder purchased from Korean markets, and to determine whether significant differences exist among various egg products, since a variety of products are available in Korean markets and there are no recent databases for cholesterol. To evaluate the cholesterol content in chicken egg sold in Korean local market, a simple method using non-heated saponification to determine cholesterol for emulsified foods was applied. The results of recovery for egg and egg powder were in a range of 92.4-105.0%, with a relative standard deviation between 1.1% and 2.8% by using gas chromatography-flame ionization detector. Therefore, the total cholesterol content in whole egg was estimated between 160.8 and 226.3 mg/egg (AV(average) $186.8{\pm}3.5$), which is similar or lower than previously reported levels. The value for cholesterol in egg powder was estimated between 2.94 and 3.49 mg/g (AV $3.23{\pm}0.15$). We suggested method that can be applicable to chicken egg and egg powder matrix as providing rapid and accurate determination of cholesterol in egg and egg powder. This information will be helpful for processed food producers for deciding food labels of cholesterol content.

There are many software reliability models that are based on the times of occurrences of errors in the debugging of software. It is shown that it is possible to do asymptotic likelihood inference for software reliability models based on infinite failure model and non-homogeneous Poisson Processes (NHPP). For someone making a decision about when to market software, the conditional failure rate is an important variables. The finite failure model are used in a wide variety of practical situations. Their use in characterization problems, detection of outliers, linear estimation, study of system reliability, life-testing, survival analysis, data compression and many other fields can be seen from the many study. Statistical Process Control (SPC) can monitor the forecasting of software failure and there by contribute significantly to the improvement of software reliability. Control charts are widely used for software process control in the software industry. In this paper, we proposed a control mechanism based on NHPP using mean value function of log Poission, log-linear and Parto distribution.

Fuel cell systems have to satisfy acceptable operating reliability, sufficient lifetime and price to enter the market in competition with existing products. Fuel cells are made up of complex element technologies and various problems related to the failure of the components can affect the reliability and safety of the system. This problem can be overcome by introducing a monitoring and supervisory control system in addition to automatic control to detect the failure of the fuel cell quickly and properly diagnose the performance degradation. For the fault detection and diagnosis of polymer electrolyte fuel cells, the model based method using the theoretical superposition value and the non-model based method of checking the signal tendency or the converted signal characteristic can be applied. The methods analyzed in this paper can contribute to the development of integrated monitoring and control technology for the whole system as well as the stack.
