Online news on the Internet, as published open data, contain facts or opinions about a specific affair and hence influences considerably on the decisions of the general publics who are interested in a particular issue. Therefore, we can predict the people's choices related with the issue by analyzing a large number of related internet news. This study aims to propose a text analysis methodto predict the outcomes of events that take place in a specific place. We used topics of the news articles because the topics contains more essential text than the news articles. Moreover, when it comes to mobile environment, people tend to rely more on the news topics before clicking into the news articles. We collected the titles of news articles and divided them into the learning and evaluation data set. Morphemes are extracted and their polarity values are identified with the learning data. Then we analyzed the sensitivity of the entire articles. As a result, the prediction success rate was 70.6% and it showed a clear difference with other analytical methods to compare. Derived prediction information will be helpful in determining the expected demand of goods when preparing the event.

Borehole image analysis has been carried out to obtain the detailed geological data by approach of direct observation. Direct application of borehole image analysis inevitably gives rise to a few of restriction of data acquisition due to the limited information within narrow borehole space. Considering the apparent dip of discontinuity surface depending upon the direction, the visualized program of two-dimensional subsurface discontinuities is coded. Borehole image analysis can compensate the distribution of subsurface discontinuity extending into the expected area of investigation. In order to draw subsurface profile in the proposed area of subsurface construction, visualized program is coded as a window GUI (Graphic User Interface) using Fortran and Visual Basic Programming languages. It is to open publicly for the usage of whoever is in want. Discontinuity distribution map is visualized along the Proposed line of tunnel in the Janggye-ri area, Jangsu-gun. Using the visualized program, the limited information from borehole spatially applies into analysis of overall subsurface structures, and the distributional characteristics of discontinuity anticipate at the proposed area. In addition, spacing and extension of joint and depth of discontinuity effecting tunnel safety can be visualized along the direction of the proposed tunnel. These lines of visualization apply design and construction of fundanmental structures.

Philosophical and social backgrounds and inquiring into new direction of Practical Arts and Home Economics Education is done through this paper. The overall review of the related documents, records, books has been done, and research findings are presented as follows; Thought(Educational theory and Philosophy) for Korean Practical Arts Education is based on Learning to Labor, Practical Science and Pragmatism. Korean curriculum for Home Economics were originated in Confucianism background, which stressed the importance of different gender roles for men and women. However, Korean Home Economics based on Home Economics Subject Matter has been developed without philosophical base unlike that of American Pragmatism and Critical Theory. Therefore, scientific recognition in a section of value recognition was separated and developed so far. Thus, we could not answer to social missions about keeping values of life corresponding with changing environment I also observed the analysis of revision curriculum of the mentioned subject, and the changes of concepts of Work and Prasix, necessity of Home Economics Education for fixing about a basic life education and a basic life skill, and reinforcement of the function in Home. And then, new directions is proposed that the role of Home Economics Education in school be reinforced for the upcoming low birth rate and the aging society(high proportion of the aged people). Because Characters on correct values of children and youths might be nurtured in home foremost.

The objective of this study is to evaluate the effect of the water quality improvement by water discharge through dams and to provide a benefit estimation methodology, taking domestic situation into consideration, by the replacement cost approach analyzed with a sewage treatment plant instead of an alternative dam. To this end, facility that alternates a dam must have same functions of the discharged water from the dam and the two facilities must be able to be compared objectively. To estimate the benefit, estimation methodology of alternative facility's cost is established and criteria of cost.benefit analysis that are duration period and ratio of large scale repairing expense was presented. As a case study, the water quality improvement benefit of Song-Li-Won dam was evaluated, which is planned to be built on Nae-Sung stream in Nak-Dong River system. The results of applying this methodology to Song-Li-Won dam are 644,006 million won of the annual average discharge and 1,351,526 million won of maximum discharge. The usage of the framework in this study is expected for estimation of water quality improvement benefit in case water quality improvement project is performed.

What is a role of the studies on spatial planning of Korean peninsular and its cities in the process of cooperation between and unification of South and North Korea? Where should the basic perspectives be oriented for the process? Can a comprehensive plan of North Korea have practical implications although South-North cooperation does not get into its stride? If it can, which contents should the plan cover? This study aims to contemplate these issues and to suggest a preliminary land development approach of North Korea, which would contribute academic and practical debates on the issues, at this juncture of the cascade of studies on spatial planning in North Korea. It assume South-North relation would evolve from 'reconciliation and cooperation' and 'confederation' into 'unification' of South and North Korea which is based on the official plan of South Korea. We suggest, as the basic perspectives of development approach, cooperation(or co-evolution), future-oriented sustainability, and parallel development of industry and physical infrastructure. The development potential of North Korea is explained by detail fields and sub-regions, which is used to analyse SWOT and to subsequently extract the basic directions(vision and strategies) of North Korea development. These directions are followed by the spatial structure plan to improve North Korea using the potential of the regions. Based on the plan, the development directions of detail fields are suggested.

This study aimed at the identity of the landscape architectural award, which is the highest authority award system in landscape architecture; the establishment of cooperation between the landscape architecture and urban public sector, which deals with infrastructure is significantly requested nowadays. The identity characteristic of a detailed concept which configures the sameness in the shape of inner self-cognition and individuality as external and correlative cognition are utilized as the research methodology, and the findings are summarized as follows. The Korean Landscape Architectural Award holds an internal value as the only award in landscape architecture that is granted municipalities and public agencies. However, when it is compared with several correlated award systems, the vulnerable sides such as short origin and partly limping in terms of sustainability, the possibilities of losing the interest in the public sector due to management's reform program and insufficient participants and responses regarding social authority have been found. In addition, according to the today's paradigm tha taims for green cities, the aspect that shares the large portion with the values set by detailed categories of city planning that enforces metropolis awards is also in the spotlight. Hence, the landscape architectural award should construct specialization and development strategies by strengthening the superiority compared with the city award in the field of city planning. In other words, the Ministry of Land, not limited to the systematic cooperation with various administrative areas will be strengthened and it will communicate with the aspect that reinforces characters as an academic and practical area that covers various districts and disciplines. Thus, the identity is directly connected to the landscape architectural award's competitive reinforcement as a detailed characteristic variously combined, and it requires huge interest and discussions regarding internal and external landscape architecture areas and the democratic public discussion process.

The purpose of this study is to develop a plan to improve the status of local autonomous body ordinances applying disability grades according to welfare law for people with disabilities. The results are that First, 215 of the total municipalities applied the disability grade, and 1,071 cases were applied to the disability welfare law. Among them, 60.04% (643 cases) of the ordinance that can be divided into severe (1-3 grade) and mild (4-6 grade) were found, and 39.96% (428 cases). A new service eligibility standard that reflects factors such as the needs of persons with disabilities, social environment, etc. needs to be developed. Second, since the exemption reduction service accounts for more than 40% of all projects, it is necessary to set the standards considering the other standards within the scope of not decreasing the total service amount when revising the ordinance. Based on these results, We will provide important basic data for establishing new service provision criteria to replace the disability level at the local government level.

The goal of this paper is the pedagogical application of a Korean Spell/Grammar Checker to the web-based language learning system for Korean writing. To maximize the efficient instruction of our learning system \\`Urimal Baeumteo\\` we have to improve our Korean Spell/Grammar Checker. Today the NLP system\\`s performance defends on its semantic processing capability. In our Korean Spell/Grammar Checker. the tasks accomplished in the semantic level are: the detection and correction of misused derived and compound nouns in a Korean spell-checking device and the detection and correction of syntactic and semantic errors in a Korean grammars-checking device. We describe a common approach to the partial parsing using collocation rules based on the dependency grammar. To provide more detailed semantic rules. we classified nouns according to their concepts. and subcategorized verbs referring to their syntactic and semantic features. Improving a Korean Spell/Gl-Grammar Checker makes our learning system active and intelligent in a web-based environment. We acknowledge the flaws in our system: the classification of nouns based on their meanings and concepts is a time consuming task. the analytic unit of this study is principally limited to the phrases in a sentence therefore the accurate parsing of embedded sentences remains a difficult problem to solve. Concerning the web-based language learning system. it is critically important to consider its interface design and structure of its contents.

To measure the amount of nonpoint source pollution, some efforts are tried to utilize satellite imagery. But, as the factors for water models do not relate with the landcover categories for satellite imagery, satellite imagery are adapted to roughly classified thematic map or used only for the image interpretation. The purpose of this study is to establish the landcover categories of satellite imagery to relate with the water models. To establish the categories of the landcover for the water models, it was investigated to get main factors of water flow models for the nonpoint source pollution and to review the existing study and the classification system. For this result, it was convinced that the basic unit on the nonpoint source pollution, landcover coefficients of SCS Curve Number, the crop factor of Universal Soil Loss Equation, Manning's roughness coefficients are the useful parameters to extract information from the satellite imagery. After the setup the categories for the landcover classification, it was finally defined from the consultation of the water model specialist. Woopo wetland watershed was selected to the study area because it is a representative wetland in Korea and needs the management system for nonpoint source pollution. There were used Landsat ETM Plus and SPOT-5 satellite imagery to assess the result of the image classification.

There has been increasing the possibility of occurring the marine accident and become bigger the extent of damage with the growing number and high speed of ships. Also, there were tremendous loss of lives and properties in accidents of Hebei spirit in 2007 and Cheon Ahan war ship in 2010 with the insufficient salvage response and the lack of emergency response systems. When a ship has suffered an incident, the best way of preventing damage or pollution from its progressive deterioration would be to providing a place of refuge and to repair the damage rapidly. Therefore, it was examined the recent collision accident broken out near the Nam-Hae, and then suggested that it was necessary to be improved of the domestic salvage systems. It requires the procedures of providing a place of refuge, and the towing support system which make the damaged ship moved to the safe area, and joining of the ISU.
