Because of the trend of deregulation, power industry is going through an unprecedented transformation in North America and Europe, and there are a host of acquisitions and mergers by the private sector to position themselves to take advantage of new business opportunities. Deregulation has accelerated the development of smaller generators and fuel cells will gradually become more attractive to mainstream electricity users as they improve in capability and decrease in cost. Fuel Cell technology is surveyed and the potential of using fuel cell as a distributed generation source is presented. This paper recommends the fuel cell power plants as alternative energy sources for distributed generation in Jeju Island, Korea. This will help in increasing fuel efficiency, at least double the current thermal plants', increasing the reliability of power supply, reducing the dependency on the HVDC link, providing quality power to the growing infrastructure, and maintaining clean air in meeting the free-trade international island.

Background: In times of continuous change and volatile markets, organizations are increasingly characterized by downsizing, work intensification, and resource rationalization. This has resulted in diversification, and the emergence of newrisks within the field of occupational health and safety, with an important impact. This paper focuses on one such type of risk in the modern workplace-psychosocial risks. The current study aimed to explore stakeholder perspectives, regarding the extent to which psychosocial risks are incorporated into strategic risk management practices, at both the business and policy level. Methods: Semi-structured interviews were conducted with 14 professionals, representing employer, expert, policy maker, and trade union stakeholder perspectives. Results: It was found that the majority of organizations do not sufficiently, if at all, understand and incorporate psychosocial risks into strategic decision making, whereby the key barrier related to practical difficulties of not knowing how to manage psychosocial risks adequately. Conclusion: The study found that there is a need to close the gap between policy and practice on a number of levels. Future recommendations comprise a policy framework and infrastructure underpinned by educational initiatives, partnerships, and networks to drive a shift in attitudes toward recognizing the duality of the concept of risk (including both potential negative and positive outcomes) and moving beyond simple regulatory compliance.

In this article, I have reviewed the validity of the Retla Clauses in bills of lading. In Tokio Marine(1970), US courts have permitted carriers to include Retla Clauses in their bills of lading that essentially disclaim all responsibility for the required statement. Simon J in The Saga Explorer(2012) disagreed with the decision of no representation in Tokio Marine and held that the statement with the Retla Clauses made on the bills of lading as to the cargo's apparent condition was a fraudulent misrepresentation. Simon J also requested a strong carriers' honest conduct. However, because the shippers always request the clean bill of lading for trade purpose and never call for a substitute bill of lading showing the true condition of goods, carriers will inevitably continue to clause bills of lading if they have no other better way of protecting themselves in the situation of Tokio Marine or The Saga Explorer. For the present, the decision of misrepresentation in The Saga Explorer might be helpless to change the position of the assignees of the bills of lading. And it seems that the debate on the validity of the Retla Clauses in bills of lading will be continued for the time being. In these circumstances, if the buyers hope to void the potential dispute, they may have a special agreement in the sale of goods contract, for example, requiring a pre-shipment inspection of the goods so as to know the actual condition of the goods on shipment.

Two types of responses to climate change exist. First is climate mitigation which includes efforts of reducing CO2 and GHG emissions. Second response is climate adaptation process which is establishing climate resilience in the supply chain. The two are inherently different since mitigation strategy focus on eliminating the source of climate change and is long term in nature but adaptation strategy is moderating the impact of potential or current climate change. In order to embed climate resilience in the supply chain, mitigation strategies and adaption strategies must be implemented simultaneously. Corporation's adaptation to climate change related natural disaster can be seen as a response that includes mitigation and adaptation strategies simultaneously. A comprehensive climate change resilience supply chain approach has to be developed. This paper illustrated guidelines and adaptation process framework businesses can utilize in order to build climate resilience. Screening process before the actual assessment of risk was introduced as well as the whole adaptation process of establishing information system and strengthening climate-related operational flexibility.

This study, not only investigates the important role of lifelong learning in shaping young people's knowledge and in maximizing their potential, but also aims to shed light on the influencing factors of lifelong learning of young people in Vietnam. The author applied STATA and SPSS to analyze quantitative data collected from questionnaires with 332 respondents aged between 19 years old and 24 years old. Based on a holistic review of literature, this study concludes that four driver factors affect young people's lifelong learning ability, comprising: organizational culture, motivation, human resource development, and domestic private type of enterprise. The results emphasize the positivity of organizational culture, human resource development, and the nature of work, especially organizational culture and human resource development, which are dominant reasons for young people to maintain lifelong learning. The relationship between demographics and lifelong learning was tested and it indicated that male has a stronger interest in learning than female. The result of the study also shows the impact of different types of business sectors on employees' learning intentions. It points out that the domestic private type of enterprise is the most effective factor that has a positive relationship with the lifelong learning of the individual.

With the strong growth of social networking sites such as Facebook in recent years, the potential of exploiting customers on Facebook is increasing. Presently, trading activities on Facebook is rapidly developing. Therefore, businesses have become increasingly competitive when selling products on Facebook, so as to retain customers as well as to satisfy customer, which is of paramount importance. This study was conducted to assess the factors affecting the satisfaction of individual customers in Vietnam when buying goods on Facebook. This study uses multivariate analysis techniques (Confirmatory Factor Analysis, Structural Equation Modeling) to determine the factors affecting customer satisfaction when buying goods on Facebook. Research results from 268 individual customers in Vietnam indicated trust and convenience are the two important factors related to customer satisfaction when buying goods on Facebook. Customer satisfaction is the result of consumer experience throughout the different stages of purchase. The more the shopping experience, the more the customers are satisfied when buying products. The price and products do not affect customer satisfaction (prices are easy to compare and products are easily understood on the Internet; hence, these two factors are not considered as determinants of customer satisfaction). Furthermore, this study provides recommendations to improve customer satisfaction.

Low-power and lossy networks (LLNs) comprised of thousands of embedded networking devices can be used in a variety of applications, such as smart grid automated metering infrastructures (AMIs) and wireless sensor networks. Connecting these LLNs to the Internet has even greater potential, leading to the emerging concept of the Internet of Things (IoT). With the goal of integrating LLNs into IoT, the IETF has recently standardized RPL and 6LoWPAN to allow the use of IPv6 on LLNs. Although there already exist several studies on the the performance of RPL and embedded IPv6 stack in LLN, performance measurement and characterization of TCP over RPL in multihop LLNs is yet to be studied. In this article, we present a comprehensive experimental study on the performance of TCP over RPL in an embedded IPv6-based LLN running over a 30-node multihop IEEE 802.15.4 testbed network. Our results and findings are aimed at investigating how embedded TCP interoperates with common Linux TCP and underlying RPL (and vice versa), which furthers our understanding of the performance trade-offs when choosing TCP over RPL in IPv6-based LLNs.

These days the international environmental regulations of the developed countries, especially from the EU, are rapidly changed to the regulations of product-based environment from a conventional end-of-pipe environmental technology. Especially the motive in this paper come from the EU's electrical and electronic equipment environment regulation. It may affect much to whole export of Korea Firms Integrated product policy has the potential to increase not only competitive power in today's global market, but also trade compatibility between countries. Furthermore it is important to make a contribution to sustainable development. CEOs must change their notions about firms' environmental policy from the end-of-pipe approach to the sustainable approach to improve company's competitive power. As emphasized a paradigm of naw environmental management by EU' environmental directives, the company must establish clean production system to save resources and reduces pollutant. Also Korean Company constructs a systematical network to collect EU' environmental regulation information which are changing rapidly. Large company will cooperate with small and medium-sized firm for their win-win strategy in the field of environmental management. Also it is necessary to make the domestic regulations of product-based environment to meet the international environmental regulations.

An integrated water environment management system is necessary in improving water quality, properly allocating water resources, and supporting socio-economic development. Specifically, water quality management system using web map can be an efficient approach to accomplish this system. This paper aims to construct a dynamic water quality management system to reflect a water environment management system which includes three sub-models with consideration of their interrelationships (a socio-economic model based on dynamic Input-Output model, a water resources cycle model, and a water pollutants flow model). Based on simulation, the model can precisely estimate trends of water utilization, water quality, and economic development under certain management targets, and propose an optimal plan. This study utilized the model to analyze the potential of using reclaimed water to accomplish local water environment management and sustainable development plan while exploring the applicable approaches. This study indicates that the constructed water environment management system can be effective and easily adopted to assess water resources and environment while improving the trade-off between economic and environment development, as well as formulate regional development plan.

The preferential Rules of Origin (RoO) govern tariff preferences that are given in accordance with the FTA. However, relatively few studies have been devoted to the procedures in settling disputes that are relevant to RoO under the FTA. This study is a first attempt at analyzing the applicability and the potential improvement in dispute settlement procedures in FTAs targeted at the preferential RoO. By exploring three dispute cases involving the preferential RoO, it is suggested that restrictiveness, complexity, and uncertainty that are inherent in the preferential RoO may trigger political tension and dispute. Forming a panel that is capable of mitigating political tension, facilitating participation and early cooperation of experts and stakeholders, and establishing a well-structured enforcement procedure are essential in dispute settlement procedures to resolve disputes involving cases on RoO. Furthermore, the current dispute settlement procedure that hinders the private sector's access should be changed to one that is more open to private sector entities, such as companies, to facilitate the enforcement of the decision. Given that more improved FTA dispute settlement procedure may guarantee the enforcement and application of the FTA preferential treatment in relation with more politically powerful states and foster genuine free trades, more in-depth studies must be conducted on this topic.
