ABB-CE＇s regionalization methodology for the core inlet flow distribution map is reviewed. This methodology merges the test data of fuel assembly locations which are either in symmetry or strongly correlated with others. It increases the number of available test data for each regional flow factor It makes up effectively for the deficiency due to limited number of test data. It also contributes to making the core inlet flow distribution smoother not only locally but also over the entire core, and to relieving the impacts of test errors that may happen due to some do- calibrated local pressure measurement taps. As a result, the core inlet How distribution data becomes more statistically useful and thus the conservatism involved in handling the core inlet flow factors for the thermal margin analysis is expected to be reduced. Meanwhile, the regionalized map may lose the unique local characteristics in core inlet flow distribution too much. By an alternative approach introduced in the present work, it is shown that such a disadvantage can be mitigated somewhat if the engineering judgement is made more

For container shipping company, fuel oil prise is a considerable expense. Since 2008, fuel oil prises have risen dramatically. An increasing fuel oil price in container shipping, in the short term, is only partially compensated through surcharges and may affect earnings negatively. This study discusses the impact of an increasing fuel oil price and capital costs for vessels on the Asia-Europe trade of 'H' Shipping Company. According to the result of 'H' carrier's operation in 2008, there were no cost differences between 8 and 9 vessels operations in case of fuel oil price with USD 169/tons while adopting USD 31,818 as a fixed cost. We can expect that the fuel oil price will not go lower than USD 200/Ton on the basis of current high oil price phenomenon. When the fuel oil price is over USD 200/ton, 9 vessel operation is more economic than 8 vessel operation even if the fixed cost is over USD 35,000.

This research is a construct to understand CSR and pro-social consumption behavior of fashion consumers which classifies CSR efforts of fashion company and conducts positive analysis of the relationship between such characteristics and social relationship behaviors(sharing of values, consciousness of kind, consciousness of future expectation) and pro-social consumption behavior. For this path analysis was conducted utilizing a sample of 430 consumers who have experience of CSR efforts of fashion brands. The result is as follows. First, as a result of the path relationship among CSR efforts & sharing of values of fashion brands, consciousness of kind and consciousness of future expectation, economic efforts, relational efforts and cyclical efforts meaningfully affected sharing of values, whereas creative efforts did not. Also, relational and creative efforts meaningfully affected consciousness of kind, whereas economic and cyclical efforts did not. Furthermore, economic, relational and cyclical efforts meaningfully affected consciousness of future expectation, when creative efforts failed. Second, as a result of the analysis of path relationship among sharing of values, consciousness of kind, consciousness of future expectation and pro-social consumption behavior of social relationships, sharing of values had a meaningful impact on consciousness of kind, consciousness of future expectation and pro-social consumption behavior. And finally consciousness of kind and future expectation showed meaningful influence on pro-social consumption behavior.

Purpose - This study aims to clarify the meanings of small enterprise and modify criteria for explaining its range. Prioritizing the number of full time workers first and the sales next are proper as a new concept and range. Research design, data, and methodology - In research, 'small company' is a basic concept because the range of its standard is categorized as a 'small company' in the policy system of small & medium business. This study focuses on the solutions with ① evaluation on sales, ② standard for excluded ones ③ regulation for excluded business types in 'Act on Protection and Support for Small Enterprise'. Results - Clarifying the range of standard with maintaining the title is advisable. The scope should resist the current criteria or adopt a new standard which contains not only full time workers but also the sales. The new one may raise the policies' effectiveness because it can sort the 1% people of small enterprises. Conclusions - However, there should be a preventive system for sorting out the non-eligible ones not conformed to the CAP for small company. Therefore, it is desirable to prepare the system with 'unsuitable ones list' or regulate large income·inappropriate business types in 'Act on protection and support for small enterprise'.

This study examines the time causal relationship between the operation profit of the listed fashion companies and the macro variables. Operating profit data of 36 listed fashion companies from 2000 to 2017 has been used. Macro variables include household income, household expenditure, number of Korean overseas travelers, number of foreigner travelers and sentiment index. The study results are as follows. First, the number of outbound travelers from Korea has a negative effect on the operating profit of listed fashion companies; however the number of foreigner visiting Korea has a positive effect at 0 time lag. Second, the consumer sentiment index had a positive effect on the sales and the operating profits of the listed fashion companies with a time difference between the 3rd and the 4th quarter. Third, a disposable income has a positive effect on the operating profit of listed fashion companies. Last, educational expenses have a negative effect on operating profit with a time lag between the first and the second quarter. The findings can be used as useful information to analyze the fashion industry and help fashion companies improve their financial performances.

This study conducted to predict the stock market prices based on the assumption that internet news articles might have an impact and effect on the rise and fall of stock market prices. The internet news articles were tested to evaluate the accuracy by comparing predicted values of the actual stock index and the forecasting models of the companies. This paper collected stock news from the internet, and analyzed and identified the relationship with the stock price index. Since the internet news contents consist mainly of unstructured texts, this study used text mining technique and multiple regression analysis technique to analyze news articles. A company H as a representative automobile manufacturing company was selected, and prediction models for the stock price index of company H was presented. Thus two prediction models for forecasting the upturn and decline of H stock index is derived and presented. Among the two prediction models, the error value of the prediction model (1) is low, and so the prediction performance of the model (1) is relatively better than that of the prediction model (2). As the further research, if the contents of this study are supplemented by real artificial intelligent investment decision system and applied to real investment, more practical research results will be able to be developed.

Since IMO has discussed the effectuation of the EEDI, EEOI and SEEMP, each country, shipping company, shipbuilding company and research institute have been requested to prepare the design, construction and operation of the efficient ship. From the shipbuilding company's point of view, it was necessary to develop a method based on the maneuvering equations of motion in a bid to estimate the EEOI considering the design, model test results and the calculation results of the ship. In this paper, the estimation method of RPM, power and fuel consumption proposed in the previous research was developed to construct a framework that helps in the estimation of the EEOI. It was possible to estimate the EEOI from the estimated ship speed (distance), LNG cargo mass, fuel consumptions and emission factors according to the type of fuel. The rapid increase of the evaluated EEOI was observed when the LNGC with ME-GI engine executing the course changed with a large difference. This prompted the comparison of the type of fuel on the estimated EEOI by considering HFO, LNG fuel and MGO properties.
