The purpose of this paper is to estimate economic benefits for the investment of railway transshipment system with non-powered turntable. The freight transport by railway can have decided advantages over trucks in terms of energy efficiency, emissions and cost for certain freight movements, just as transportation in the metropolitan region can have great advantages over driving truck. But the freight transport by truck should gain significant mobility benefits from a freight railway system. Thus, the railway transshipment system with non-powered turntable which is coupled railway transport advantages with load transport advantages has been developed and used in the european countries. This research has conducted the empirical analysis, by calculating the investment of railway transshipment system with non-powered turntable. The key factor for the economic benefits for the non-powered turntable is the utilizing throughputs. This demand is influenced by the throughput in the railway transshipment system. The main results of this paper are as follows: railway transshipment system with non-powered turntable does not have economic benefit for investment. We recommend that the plan for investment has to be considered the modification.

Purpose - This paper studies whether economic sanctions can be used as grounds for a party to an international sales contract to get an exemption if he fails to meet his contractual obligation. Because the answer can differ depending on the governing law of the contract, this study focuses on CISG, the most widely recognized international uniform legal instrument as the governing law of the international sale of goods. Design/methodology - This paper focuses on analyzing the conditions to meet before getting an exemption under CISG. For such analysis, this paper examined various scholarly writings, cases, and hypothetical examples reflecting a wide variety of economic sanction measures. Findings - The findings of this paper are as follows. The main provision for exemption under CISG is Article 79(1), which provides for an exemption for a party that failed to perform if such failure was caused by an impediment that was uncontrollable, unforeseeable, and unavoidable; either a seller or a buyer may rely on the Article for his non-performance, delay, or defective performance. The Article is applicable not only where the economic sanction caused impossibility of performance but also where it caused hardship. The economic sanction will likely be found to be an uncontrollable impediment; however, it will be relatively more difficult to prove it to be unforeseeable or unavoidable. Originality/value - The subject of this paper is whether a party can be exempted from liability under CISG when he fails to perform his contractual obligations due to economic sanctions. Given that this issue is now actually faced by many involved in international trade, it is expected to provide practical help to practitioners and companies alike.

Economic evaluations in the healthcare are used to assess economic efficiency of pharmaceuticals and medical interventions such as diagnoses and medical procedures. This study introduces the main concepts of economic evaluation across its key steps: planning, outcome and cost calculation, modeling, cost-effectiveness results, uncertainty analysis, and decision-making. When planning an economic evaluation, we determine the study population, intervention, comparators, perspectives, time horizon, discount rates, and type of economic evaluation. In healthcare economic evaluations, outcomes include changes in mortality, the survival rate, life years, and quality-adjusted life years, while costs include medical, non-medical, and productivity costs. Model-based economic evaluations, including decision tree and Markov models, are mainly used to calculate the total costs and total effects. In cost-effectiveness or costutility analyses, cost-effectiveness is evaluated using the incremental cost-effectiveness ratio, which is the additional cost per one additional unit of effectiveness gained by an intervention compared with a comparator. All outcomes have uncertainties owing to limited evidence, diverse methodologies, and unexplained variation. Thus, researchers should review these uncertainties and confirm their robustness. We hope to contribute to the establishment and dissemination of economic evaluation methodologies that reflect Korean clinical and research environment and ultimately improve the rationality of healthcare policies.

Exports of Korean non-timber forest products to the Japanese market decreased 46.3% from 17.54 million dollars in 2010 to 9.42 million dollars in 2014. This research aims to find the appropriate strategies for exporting Korean non-timber products, such as chestnut, shitake, persimmon, and wild ginseng. We applied conjoint analysis to investigate the preferences of Japanese homemakers for Korean non-timber products. The results are as follows: (1) There is a clear distinction in the preference for the attributes and levels of products; (2).Korean products are preferred to Chinese products, but have lower competitiveness than Japanese products; (3) Japanese homemakers responded sensitively, not to the forest product prices, but to changes in their specific attributes. These results can be used to promote the export of Korean non-timber products to the Japanese market.

This study examines the measures for the activation and the growth of intra-regional trade in Southeast Asia taking a look at the four dimensions of tariff rates, non-tariff barriers, trade facilitations, and trade infrastructures. Utilizing a gravity model, we performed empirical analysis and discussed the policy implications with the priorities to implement. To expand the intra-regional trade in Southeast Asia it would be necessary to enhance the level of trade facilitations and provide trade infrastructures, such as ports and airports as well as cutting the tariff rates and eliminating the non-trade barriers. In particular, in the case of exports of ASEAN6 to ASEAN6 the infrastructure is the important factor. Also, in the case of the exports of ASEAN6 to CLMV(Cambodia, Laos, Myanmar, and Vietnam), it is expected that eliminating non-tariff barriers and enhancing trade facilitations may play important roles in the progress of intra-regional trade. These results may provide the important implications for Southeast Asian countries, which are trying to promote intra-regional trade ahead of the constitution of ASEAN Economic Community by 2015. Southeast Asian countries could be evaluated to achieve a certain level of trade liberalization and economic integration through the formation of AFTA. But in order for Southeast Asia to develop to advanced economic integrated region it requires mutual cooperations and policy harmonizations among regional countries. Also, for the elimination of non-tariff barriers, promoting trade facilitations, and providing infrastructures, the administrative, legal, and institutional measures would have to be fulfilled in advance. In addition, capital investment for constructing infrastructures would be necessary to realize the intra-regional trade expansion. However, to achieve the goal, it would require a large capital investment and highly mandated policy considerations and harmonizations among Southeast Asian countries in terms of further trade liberalization and economic integration.

The economic design of specification limits must be determined on an economic basis where we minimize total loss to society, which consists of both the producer and the consumer. Economic specification limits have been developed based on the assumption that the quality characteristic is normally distributed. Unfortunately, the assumption is not to meet some practical cases. In this paper, some non-normal distributions are considered for quality characteristic with geometrical features. An economic model for selecting the optimum specification limits on the basis of minimizing total cost is introduced. A case study is presented to illustrate the application in practice.

This thesis introduces the trends of korean courts' ruling on damages in medical malpractice cases for past 10 years. First of all, Korean courts' ruling have had a tendency to pay only non-economic damages for not taking the informed consent. If a doctor cannot get the informed consent from a patient, he compensate only non-economic damages for the infringement of self-determination rights of patient. It's enough for the plaintiff to prove the infringement of self-determination rights, if the plaintiff just want to get non-economic damages. The Korean Supreme court have ruled that if plaintiffs want to get economic damages for the infringement of self-determination rights or informed consent, plaintiffs must prove that the infringement of self-determination rights is the proximate cause of the economic damages of patient. There is another tendency for the Korean Supreme court to limit the damages in medical malpractice cases on the ground of patient's diseases' dangerousness or patient's idiosyncrasy. In the past courts often limit the damages only to 70~80% of total damages, but now a days courts mostly limit the damages to 20~30%. This thesis also introduce the Korean courts' trends about Valuing damages in personal injury actions awarded for gratuitously rendered nursing and medical care.

Objective: The bobsleigh shoes used in the start section are one of the most important equipment for improving the competition. Despite the importance of the start section, there are no shoes that are specific for bobsleigh athletes in Korea and Korean athletes have to wear sprint spike shoes and practice the start instead of wearing bobsleigh shoes. The objective of the present study was to provide data for improving the performance of Korean bobsleigh athletes by investigating the differences in their split time, plantar pressure, and forefoot bending angle based on skill levels at the start of a run under the same conditions as training conditions. Method: Six Korean bobsleigh athletes were divided into two groups, superior (n=3) and non-superior (n=3). A digital speedometer measured the split time at the start; the Pedar-X system (Novel, Germany) measured plantar pressure. Plantar pressures and split times were measured as the athletes pushed a bobsleigh and sprinted at full speed from the start line to the 10-m mark on the bobsleigh track. An ultra-high-speed camera was used to measure the forefoot bending angle during the start phase. Results: Significant between-group differences were found in split times (p<.000; superior = 2.38 s, non-superior = 2.52 s). The superior group had a larger rearfoot (p<.05) contact area, maximum rearfoot force (p<.01), and a larger change in angles 3 and 4 (p<.05). Conclusion: At the start of a bobsleigh run, proper use of the rearfoot for achieving effective driving force and increasing frictional resistance through a wider frictional force can shorten start time.

There are two viewpoints in agricultural extension. One is economics(econometrics) the is non-econometric social sciences. In Korea economic means mainstream economics. Most mainstream economists have tried to solve the social and economic problems of Korea using their basic principles and econometrics. This mainstream economics have been supported by the Korean government and many people due to its convenience, effectiveness, and clearness. However, Agriculture and agricultural extension should be studied through multidisciplinary approaches after considering their specific social structures. Especially, Korean agriculture and agricultural extension have many aspects that can not be easily explained by main stream economics. In this study, the researchers will; 1)identify the origin, growth, and limitation of mainstream economics, i.e. econometrics 2)identify the paradigm and the view of social sciences and out-of-mainstream economics to make up for the limitation of main stream economics in explain the agriculture and agricultural extension in Korea, and 3)suggest to use multidisciplinary approaches to solve the agriculture and agricultural extension in Korea.

This study reviewed how the changes of the government policy on solar power generation projects affected the annual mandatory quotas of the regulated power providers under the RPS (renewable portfolio standard) system and analysed economic feasibility of the investment for meeting their quotas as compared to the case of non-regulated power providers. The analysis results showed that under the discount rate of 7.5%, which was used for the annual national electricity plans for the recent years, both the regulated and non-regulated power providers achieved economic feasibility under both the NPV (net present value) method and the real option pricing method. It was also shown that higher profitability was attained by non-regulated power providers than by their regulated counterparts, which can be attributable to the fact that regulated providers are required to out-source 50% of the total quota. The results of this study are considered to be useful for establishing a meaningful mid term or long term strategy for the future of solar power generation linked to the current RPS system.
