This study is focused on the cases that Korean hotels stepped into international airports, public facilities, and successfully solved the contract related disputes by using arbitration in accordance with arbitration law. This case study on arbitration derives the hotel management strategy points as follow: 1. It must be a good chance for a famed hotel to step into international airports that have big publication effect. The feasibility study focused on marketing feasibility rather than finance feasibility may, however, not be good. 2. Written contract is required in entering into a contract with government organizations. However, oral contract still exists. 3. If the contract is made to always pay the higher amount between annual minimal guarantee and sales rate in expenses of store using charge, such contract shall cause very hard sales environment from the initial stage of the contract. 4. The airports have made optional contracts for national service. Such optional contracts are, however, not free from public criticism. 5. This case study is the first case study on arbitration applied to hotels. This study shall be, therefore, frequently referred to in setting a management strategy of hotels that want to run restaurants in another facility outside themselves.

Many countries have developed a safety case suitable to their own countries in order to improve the confidence of disposal safety in deep geological disposal of high-level radioactive waste as well as to develop a disposal program and obtain its license. This study introduces and summarizes the meaning, necessity, and development process of the safety case for radioactive waste disposal. The disposal safety is also discussed in various aspects of the safety case. In addition, the status of safety case development in the foreign countries is briefly introduced for Switzerland, Japan, the United States of America, Sweden, and Finland. The strategy for the safety case development that is being developed by KAERI is also briefly introduced. Based on the safety case, we analyze the efforts necessary to improve confidence in disposal safety for high-level radioactive waste. Considering domestic situations, we propose and discuss some implementing methods for the improvement of disposal safety, such as construction of a reliable information database, understanding of processes related to safety, reduction of uncertainties in safety assessment, communication with stakeholders, and ensuring justice and transparency. This study will contribute to the understanding of the safety case for deep geological disposal and to improving confidence in disposal safety through the development of the safety case in Korea for the disposal of high-level radioactive waste.

This study evaluated the habitability of operators for main control room fires in nuclear power plants. Fire modeling (FDS v.6.0) was utilized for a fire safety assessment so that it could determine the performance of the smoke ventilation and operator habitability with the main control room. For this study, it categorized fire scenarios into three cases depending on the conditions in the HVAC system. As a result of fire modelling, it showed that Case 1 (with HVAC) would give rise to the worst situation associated with the absolute temperature, radiative heat flux, optical density, and smoke layer height as deliberating the habitability and smoke ventilation. On the other hand, it showed that Cases 2 (w/o HVAC) and 3 can maintain much safer situations than Case 1. In the case of temperature at 820 s, Cases 2 and 3 were up to approximately 63% greater than Case 1 in the wake of ignition. In addition, the influence of radiative heat flux of Case 1 was even larger than Cases 2 and 3. That is, the radiative heat fluxes of Cases 2 and 3 were approximately 68% higher than Case 1. Furthermore, when it comes to considering the optical density, Case 1 was approximately 93% greater than Cases 2 and 3. Accordingly, it expected that the HVAC system can influence a the performance on the smoke ventilation that can be sustainable for operator habitability. On the other hand, it revealed an inconsecutive pattern for the smoke layer height of Cases 2 and 3 because supply vents and exhaust vents were installed within the same surface.

Objectives: The purpose of this study is to evaluate the effects of Shihogayonggolmoryo-tang on climacteric symptoms. Methods: We studied 5 climacteric symptoms patients who visited Oriental Hospital of OO University from March 2012 to September 2012. We treated them with Shihogayonggolmoryo-tang, acupuncture and moxibustion. The patients of climacteric symptoms had been estimated with Kupperman's index. Results: After treatment, climacteric symptoms were improved and mean score of Kupperman's index was reduced(the first case reduce from 82 to 13 during 3 months, the second case reduce from 81 to 19 during 2 months, the third case reduce from 80 to 21 during 2 months, the fouth case reduce from 50 to 9 during 2 months, the fifth case reduce from 66 to 17 during 1 month). Conclusions: This study suggests that Shihogayonggolmoryo-tang is significantly effective on climacteric symptoms patients.

In the case of making large vocabulary speech recognition system, it is better to use the segment than the syllable or the word as the recognition unit. In this paper, we study on the basis of making biphone for Korean speech recognition. For experiments, we use the speech toolkit of OGI in U.S.A. The result shows that the recognition rate of the case in which the diphthong is established as a single unit is superior to that of the case in which the diphthong Is established as two units, i.e. a glide plus a vowel. And also, the recognition rate of the case in which the biphone is used as the recognition unit is better than that of the case in which the mono-phoneme is used.

It is necessary for prediction of recycled aggregate concrete(RAC) strength at the early stage that facilitate concrete form removal and scheduling for construction. However, to predict RAC strength is difficult because of being influenced by complicated many factors. Therefore, this research suggest optimized estimation method that can reflect many factors. One way is Case-Based Reasoning(CBR) that solved new problems by adapting solutions to similar problems solved in the past, which are solved in the case library. Other way is Artificial Neural Networks(ANN) that solved new problems by training using a set of data, which is representative of problem domain. This study is to propose comparing accuracy of the estimating the compressive strength of recycled aggregate concrete using Case-Based Reasoning(CBR) and Artificial Neural Networks(ANN).

This is a case study to analyze the role of technology licensing or transfer office (TLO) as factors of success for the spin-off from government research lab. The case company is a research lab startup, which is a joint venture through technology investment by a government research lab or university in the designated R&D parks and cash investment by the partner company. The case company listed on the stock market in 2015 reaching a market capitalization of US$ 1.2 billion. We confirm the success factors of startups pointed out in many studies: original technology, good understanding of core technology and production technology, technological competitiveness in the market. However, there is an important factor not well discussed in the previous studies, the role of TLO. TLO guided the company ownership, management, technology, and solved problems that pause business itself. The case became the sample of research lab startup and technology investment in Korea.

The case series is a descriptive study that follows a group of patients who have a similar diagnosis or who are undergoing the same procedure and is the most prevalent type of research in the field of plastic surgery. Results of case series can generate hypotheses that are useful in designing further studies, including randomized controlled trials or a prospective cohort study. However, no causal inferences should be made from case series regarding the efficacy of the investigated treatment. The authors provide a guide to the design and report on the case series.

This study investigates the effect of surface treatment on the shear strength between aluminum panel and composite plate. The aluminum panel was surface-treated by DC Plasma and the composite Plate was surface-treated by ion beam. Lap shear test and T-peel test were performed to determine the shear strength and T-peel strength. Results showed that the shear strength of surface-treated case was 2.5 times higher than that of untreated case. The T-peel strength of treated case was more than 5 times higher than that of untreated case. SEM examination showed that the strength increase of surface-treated case was due to the more spread of epoxy to the panel.

Engineering Ethics is a fundamental and essential subject and the understanding of ethics is of great importance for students in engineering courses and professional engineers. Most courses would consist of ethical tests, decision making opportunities, case studies, case methods, and group discussion. It is important to consider each case carefully, so we offer a number of hypothetical short stories to students as case methods that they cover in detail. We check the behavior decisions of students as they read the hypothetical short stories. In this study, the short story was about 200 words in length. This paper shows how, with the addition of minor changes to the text, some students changed their behavioral decisions. For example, with the addition of "if you take financial liability for the losses," some thought that they would not want to carry the debt. Other cases showed how some students disliked the majority rule. The paper shows that this arranged hypothetical short story method can often guide student's decision-making process, and can result in decreased undesirable decisions.
