The research is concerned with digitalization process and strategy of 'traditional industries'. Along with development of the Internet, new industries are emerging, while traditional industries are also rapidly shifting from old modes to new ones. Most traditional industries uy to enhance their adaptability for changing environment. The investigators argue the strategic intent of traditional industries can be categorized into the four different types. The typology consists of two axis. On the one hand, the directions of digitalization are rationalization and development of new business. On the other hand, the objects of digitalization are product and process. According to the typology, the research suggests neologism for the four strategies; product innovation strategy. new business strategy. rationalization strategy and process innovation strategy.

The purpose of the present study was to investigate the development of elementary school student's reasoning strategies used in proportional tasks. Three hundred and ninety elementary students were sampled to investigate their reasoning strategies used in Pouring Water Tasks. Results showed that 4 percentage of students used proportional reasoning strategy. By the way, about 80 % of students used qualitative guess or additive strategies to solve proportion tasks. Further, about fifth-grade or 11-year-old students began to use proportional reasoning strategy. Also, female and malt students' development of reasoning strategies improved from 1st grade across 5th grade and from 6-year-old across 11-year-old. However, female did not show the improvement of strategy development after 5th-grade or 11-year-old. However, male students showed a continuous improvement after the grade or age. In addition, students showed developmental patterns of spurts and plateau, ra thor than a linear developmental pattern. The present study also discussed educational implications of this findings in school curriculum.

A thermal-hydraulic code, named CUPID, has been being developed for the realistic analysis of transient two-phase flows in nuclear reactor components. The CUPID code development was motivated from very practical needs, including the analyses of a downcomer boiling, a two-phase flow mixing in a pool, and a two-phase flow in a direct vessel injection system. The CUPID code adopts a two-fluid, three-field model for two-phase flows, and the governing equations are solved over unstructured grids with a semi-implicit two-step method. This paper presents an overview of the CUPID code development and assessment strategy. It also presents the code couplings with a system code, MARS, and, a three-dimensional reactor kinetics code, MASTER.

This paper examines critical successful elements related to the management of new product development process. For this, we have selected a VK-X100, slim bar type cellular phone, produced by VK mobile co., which was thought as a successful product development case and then analysed the case from a concept driven strategic product development's point of view. We have performed in-depth interviews with project managers, engineers and designers to get information on the product development process and analysed huge amount of data obtained from web-sites, global market indicators, and related firms' materials to find a changing trend of market conditions. The findings suggest that the successful new Product development and management is shaped by a number of different factors, such as the business environments, firm's technological level, firm's deep market insight capabilities, nature of the product development activities, and so on. Finally, we suggested the limitation of our research and further research subjects that would be required to support our findings.

Purpose of this paper is to review series of Limits to Growth studies from its original Rome Club Report published in 1972 to the most recent one in 2012 by Jorgen Randers and finds its implications on concept and strategy of sustainable development. For this purpose first, this paper reviewed series of Limits to Growth studies in details with focus on scenarios used in simulation of world model. Second, response to the original Limit to Growth was reviewed and to see validity of its scenario based simulations, simulated results of interest variables and actual historical data up to the year 2010 was compared. Third, structure and key arguments in both studies, Limit to Growth studies and Our Common Future was explained and compared. Finally, implications of the Limit to Growth studies on concept and strategy for sustainable development was discussed. Based on the comparison, this paper argued that even if the term sustainable development was not used in the Limit to Growth at all, concept and strategies for sustainable development implied in the Limit to Growth are more clear and specific than those of Our Common Future. Since Limit to Growth studies were simulation based ones that produce detailed behaviors on interest variables, it clarifies more clearly the abstract concept of sustainable development and thus, provides specific guidelines for the direction of sustainable policy which has been suffering long from vagueness of concept of sustainable development.

The purpose of this study is to find out a significant influence of continental strategy theories on the development of maritime strategy theories. For this purpose, I examined similar and different parts of each theories and their implications when applied to different environment. In details, Chapter 2 deals with how continental strategy and maritime strategy theories are similar and different in general. In Chapter 3, I look into how Karl Clausewitz's theory that has been quoted the most by military strategy theorists had influenced over the theory of Julian Corbett, one of the representative English maritime strategy theorists. In Chapter 4, I study how the theory of Alfred Mahan that has also been quoted the most among the theories of maritime strategy had been influenced by Antoine-Henri Jomini's theory. And in Chapter 5, their contemporary implications and conclusions are drawn. According to my findings, unbelievably, the theories of maritime strategy had been influenced by existing continental strategy theories very much. Many similarities are found between them. However, at the same time, a large part of them is found significantly different from original ones especially when used to reflect the maritime distinctiveness. This means that the past maritime strategy theories and stored experience also wield influence, in many ways, yielding out much better ones in terms of applicability to changing environment. Therefore, devising new strategies with creative attitude using knowledges and experiences from both other fields and past ones is the virtue required for maritime strategists.

Robustness and controllability are the key factors in internal combustion engine commercialization. This study focuses on the combustion strategy to commercialize the low temperature diesel combustion technology. Various LTC combustion methods such as PPCI, MK and highly diluted mixing controlled LTC were conducted on 6.0L heavy duty diesel engine. To find the best feasible LTC strategy, emission level, fuel consumption and combustion safety during the combustion mode change were considered. Experiments were carried out under various engine operating conditions; engine speed & load, EGR level, injection timing. Finally, this study suggests realizable LTC combustion strategy; moderate EGR level and slight early injection are possible to considerably lower PM, NOx emission and expand LTC operating range up to 50% load without CO and HC emission.

We determined the effects of starvation, water temperature, and water flow on the onset of metamorphosis in leptocephali of the Japanese eel Anguilla japonica. Leptocephali larger than 50 mm (ca. 200 days old) were reared in 10-L tanks under different feeding, water temperature, and water flow regimes. Fasted leptocephali metamorphosed earlier and faster than did the fed ones. Metamorphosis was faster in the high water flow tank (1.2 L/min) than in the tank with flow at 0.6 L/min. The duration of metamorphosis was slightly shorter at $26^{\circ}C$ than at $23^{\circ}C$. To conclude, starvation induced the metamorphosis of artificially produced leptocephali larger than 50 mm TL. Increased water flow and water temperature both appear to induce and shorten metamorphosis.
