The purpose of this study is to identify the trend of the contents of the plan that was implemented through contents analysis on the master plan project of rural village development projects that began in 2004. Contents analysis is based on the classification of business in the detailed enforcement regulations of rural village development project. Analysis on the project contents was conducted for 30 days from June 20 to July 20 for the 132 regions established in the master plan during the period from 2004 to 2007. The results of the analysis showed the following. First, scenery facilities, rural tourism, cultural welfare and income basis projects accounted for 76.5% of the total projects. Second, with regard to investment costs depending on the contents of the projects, cultural welfare, rural tourism and income basis projects accounted for 66.3% of the total investment costs. Third, it was found out that, with regard to the trend of change in the project contents by year, income basis projects were sharply reduced whereas cultural welfare and scenery facilities projects were increased. Finally, with regard to the analysis on the projects by region, it was found that Gangwon, Gyeonggi and Chungnam gave high weight on rural tourism, whereas Gyeongbuk, Jeonnam and Jeonbuk gave low weight on rural tourism. Particularly, Gyeongnam was found to have given low weight on income basis project.

The purpose of this paper is to study the development of city parks in Japan since the 1970's. The result of investigation is as follows; (1) Regarding research of city parks since 1970, applying the qualification theory III, The researches of the park were divided into the categories as follows; ( i ) children's playground, (ii) the spatial function of green tracts of land, (iii) the evaluation of actual use viewpoint , (iv) the historical viewpoint, ( v ) the natural environment protection viewpoint, and (vi) the social capital, citizen's participation and park management viewpoint. (2) the researches of the actual use viewpoints are increasing. This trend shows that the research viewpoints have been shifted from the individual using to the various subjects of using. (3) The researches of the historical viewpoint, researches focusing on Asia are increasing. This trend shows that the research viewpoints have been shifted to the relationship between the planning and the realization. (4) The research on the natural environmental protection viewpoints has seen a large expansion from the evaluation of forest in parks. (5) The social capital, citizen's participation and park management viewpoint were increased, as well as community development and the spreading effect.

Nowadays, the trend in lunar exploration missions is shifting from prospecting lunar surface to utilizing in-situ resources and establishing sustainable bridgehead. In the past, experiments were mainly focused on rover maneuvers and equipment operations. But the current shift in trend requires more complex experiments that includes preparations for resource extraction, space construction and even space agriculture. To achieve that, the experiment requires a sophisticated simulation of the lunar environment, but we are not yet prepared for this. Particularly, in the case of lunar regolith simulants, precise physical and chemical composition with a rapid development speed rate that allows different terrains to be simulated is required. However, existing lunar regolith simulants, designed for 20th-century exploration paradigms, are not sufficient to meet the requirements of modern space exploration. In order to prepare for the latest trends in space exploration, it is necessary to innovate the methodology for producing simulants. In this study, the basic framework for lunar regolith simulant development was established to realize this goal. The framework not only has a sample database and a database of potential simulation target compositions, but also has a built-in function to automatically calculate the optimal material mixing ratio through the particle swarm optimization algorithm to reproduce the target simulation, enabling fast and accurate simulant development. Using this framework, we anticipate a more agile response to the evolving needs toward simulants for space exploration.

Shale gas is one of the resources which require lots of new technologies for commercial production and has the most reserves among unconventional gas resources for commercial production at present. Especially, the growth of shale gas industry means the significant changes of paradigm and the development of shale gas is very different from conventional gas development in terms of geology, rock mechanics, petroleum engineering, development and production engineering. In this manner, shale gas may hold the key to expanding the long-term role of gas in the global energy mix.

Since The Korean Reliability Society had been founded in 1999, development history of reliability engineering in Korea is reviewed and research outputs and papers from 2008 to current are analyzed in terms of types of industry, product life cycle, hardware vs software, and theory vs application. The purpose of this research is to review the recent reliability engineering research conducted in Korea including development history as well as published papers to identify the weakness and/or deficiencies in order to suggest the future research directions, which would contribute the development of industries in Korea.

The purpose of this study was to examine the development trend of smart fiber by textile companies in Daegu/North Gyeongsang Province. This examination includes the development fields of smart fiber, investment size, information sources and the use degree of those, research-related infrastructure, relationship between companies' characteristics and their interests in smart fiber. Research data were collected by a survey. The definition and classification(4 areas and 12 development products) of smart fiber followed ones of Smart Fiber Technology Roadmap by the Ministry of Commerce, Industry and Energy. Data were analyzed using SPSS 11.0 program for frequency, means, t-test, and $X^2$-test. Among respondents, the numbers of dying and finish companies and export traders were the highest. It revealed that 19.6% of companies were developing smart fibers. Within 12 development products, vapor permeable/waterproof fiber showed to be most being developed, while medical fiber for human has not been developed and wasn't made an investment plan for developing. It was discovered that the biggest problem of smart fiber development was the lack of experts and the best outcome of smart fiber development was preoccupation of future market. It showed that companies got information from textile fairs but didn't often use information sources. The companies appeared to have a weak intention about research of smart fiber. The more important a company considered functionality of textile products and the more innovative and stabler the company was, the higher interest in smart fiber companies had. It was concluded that textile companies in Daegu/North Gyeongsang Province were aware of the importance of smart fiber development but they were not strongly interested in it and not enthusiastic in taking action on it.

This paper proposes an approach for visualizing research trends using theme maps and extra information. The proposed algorithm includes the following steps. First, text mining is used to construct a vector space of keywords. Second, correspondence analysis is employed to reduce high-dimensionality and to express relationships between documents and keywords. Third, kernel density estimation is applied in order to generate three-dimensional data that can show the concentration of the set of documents. Fourth, a cartographical concept is adapted for visualizing research trends. Finally, relative vitalization information is provided for more accurate research trend analysis. The algorithm of the proposed approach is tested using papers about Traditional Korean Medicine.
