Construction projects are fraught with risks from cost or other overruns to accidents along with other issues. This is true whether the relevant organization is an owner, general contractor, CM, specialty-trade contractor, or other entity. When cost issues or other issues confront arise, how should an organization proceed whether attempting to gain additional compensation in terms of cost/other damages or protecting the same against such claims if they do not appear to be warranted? Enter construction cost forensics. This presentation will focus on strategies/techniques with construction cost forensics in these areas in order to be successful. Covered techniques include those to develop and analyze claims including fundamental construction cost analysis techniques. When an unexpected event disrupts a construction project, using sound analytical methods to identify the cause and quantify the extent of the issue will be important for negotiating a fair result or for obtaining a successful outcome in arbitration or litigation. Key examples of uncovering issues via construction cost forensics will be covered in this presentation.

Levelized generation cost(LGC) has been widely used in assessing feed-in tariffs(FiT) for electricity generating from new and renewable energies. Current FiTs for renewable electricity in Korea have been fixed and applied with realistic economic data by the efforts of KERI(Korea Electrotechnology Research Institute) since October 2006. Some critical issues on the estimation of LGC are, however, found in KERI's report. Major issues are the estimation of capital cost, the consideration of corporate tax, and the application of economic life cycle in the formulae for LGC. These critical issues are examined and interpreted in a correct way in this paper.

Recently several LCD TV makers including Samsung, LG and Sony actively have released LED LCD TV models on market. LED LCD TV is just which applied LED BLUs so that its color contrast ratio fairly enhance up to 1 million:1 and its thickness minimize to a few mm. Even this aspect seems somewhat to be each panel maker's strategies for prior market occupations on whole TV market. Without regard to the reasons, we do obviously meet a new era of technically advanced LCD TV. However we have still lots of problems or issues which we must overcome technically including LED chip/packaging process, secondary optics treatment, heat managements and cost reduction issues. Here I would like to forecast market volume and trend of LED LCD TV first and then discuss above almost of technical issues and suggest their possible solutions. Even these solutions looks better technologies and if they may increase production cost significantly, we will not prefer to choice that technology since lower cost policy can open the market. Finally I'm trying to suggest how well LED, as future light source, can apply to future LCD TV technologies.

This study examined the association between key audit matters (KAM) and the cost of debt. Financial records and auditors' reports were used to collect data for the fiscal years 2016 and 2017, which were the first two years after KAM was implemented in Thailand. Samples are listed companies in Thailand, where the financial system is primarily debt-based and external auditors play an important role in maintaining financial reporting quality. The final samples for the two-year period consist of 770 observations. The KAM is measured in three aspects: the number of issues, the number of words, and the readability, while the cost of debt is measured by the ratio of interest expense to total debt. The research finds that the KAM readability is significantly and negatively related to the cost of debt. Meanwhile, the number of issues and words have no significant effect on the cost of debt. The finding suggests that auditors' writing skills play a crucial role in the lending decisions of creditors.

In this paper, we propose an approach resolving inaccuracy of the low-cost redundant manipulator workspace with low encoder and low stiffness. When the manipulators are manufactured with low-cost encoders and low-cost links, the robots can run into workspace inaccuracy issues. Furthermore, trajectory generation based on conventional forward/inverse kinematics without taking into account inaccuracy issues will introduce the risk of end-effector fluctuations. Hence, we propose an optimization for the trajectory generation method based on the DDPG (Deep Deterministic Policy Gradient) algorithm for the low-cost redundant manipulators reaching the target position in Euclidean space. We designed the DDPG algorithm minimizing the distance along with the jacobian condition number. The training environment is selected with an error rate of randomly generated joint spaces in a simulator that implemented real-world physics, the test environment is a real robotic experiment and demonstrated our approach.

As the industry develops, the amount of wastes is increasing in the economic system with various needs. As a result, the environmental problems are emerging as serious social issues and all the parties are required to make their best efforts. Among the issues proposed as the environmental issues, the logistics-related issues are exhaustion of the resources, global warming, environmental pollution, and acidification and so on. In order to respond to the environmental issues of the earth, the advanced countries are setting retrenched goals, reduction of the new greenhouse gases and accomplishment of retrenched goals by cooperation between the nations. Economic activities inevitably bring environmental problems and logistics is implementing those activities. The companies should perform the roles to resolve the environmental problems as the main cause of environmental pollution. Therefore, along with spreading recognition of social demand, the companies are required to establish policies regarding the environment and they should approach the issues from the perspective of resource circulation. These environment-friendly activities are emerging as the new source of competitiveness in the logistics field. Therefore, this study analyzes the effects of environment-friendly logistics activities on the reduction of logistics cost to reduce and resolve the environmental issues such as environment preservation, recycling and so on.

This study uncovered some issues that have constrained the development of logistics performance in Cambodia. Firstly, literature review was narrowed down to include studies involving the relationship between Logistics and transportation, the relationship between the infrastructure and economic growth and the important role of logistics on economic growth and poverty reduction. Then the next step the study identified some issues related to transport infrastructure that were assumed to cause the enhancement of logistics sector. Moreover, a case study about cost and time analysis was used to address some issues of logistics cost in Cambodia comparing to its neighboring countries: Thailand and Vietnam. Based on the time and cost analysis, it revealed that the logistics cost in Cambodia is much high than Thailand and Vietnam. In addition, some logistics issues were found through other two case studies about the export and trade facilitation. The participants raised some issues related to issuance of certificate of origin, the availability of information about agreements, laws, rules, and regulations, checkpoints along the corridor and opening hours of logistics service providers and slow processes. Then the authors suggested some appropriate solutions to answer to the current issues related to transport infrastructure and logistics sector in Cambodia.
