We demonstrate how social media content can be used to predict the unemployment rate, a real-world indicator. We present a novel method for predicting the unemployment rate using social media analysis based on natural language processing and statistical modeling. The system collects social media contents including news articles, blogs, and tweets written in Korean, and then extracts data for modeling using part-of-speech tagging and sentiment analysis techniques. The autoregressive integrated moving average with exogenous variables (ARIMAX) and autoregressive with exogenous variables (ARX) models for unemployment rate prediction are fit using the analyzed data. The proposed method quantifies the social moods expressed in social media contents, whereas the existing methods simply present social tendencies. Our model derived a 27.9% improvement in error reduction compared to a Google Index-based model in the mean absolute percentage error metric.

There are many data mining techniques such as association rule, decision tree, neural network analysis, clustering, genetic algorithm, bayesian network, memory-based reasoning, etc. We analyze 2003 Gyeongnam social indicator survey data using k-means clustering technique for environmental information. Clustering is the process of grouping the data into clusters so that objects within a cluster have high similarity in comparison to one another. In this paper, we used k-means clustering of several clustering techniques. The k-means clustering is classified as a partitional clustering method. We can apply k-means clustering outputs to environmental preservation and environmental improvement.

This paper aims at measuring the quality of life in the context of social well being. To meet this purpose, several objective and subjective indicators of the quality of life were selected them the recent theoretical studies in thisfield. Then, a zuestionnaire survey was made on random sampled urban failies to find out the relationship among the two sets of indicators and the quality of family life. The data obtained from the survey were analyzed using Pearson's correlation analysis, multiple regression methods and One-way ANOVA. RESULTS : 1. The quality of life of the high-income earners is higher than that of the low-income earners. 2. The quality of life tends to be high in the family with spouse'high educational background. 3. The degree of coctribution of the objective and subjective indicator to the quality of life was very high. 4. The objective indicator and the subjective indicator concerning the quality of life was closely related.

This paper presents a method of the regional long-term load forecasting considering economic indicator with the assuption that energy demands proportionally increases with the economic indicators. For the accurate load forecasting, it is very important to scrutinize the correlation among the regional electric power demands, economic indicator and other characteristics because load forecasting results may vary depending on many different factors such as electric power demands, gross products, social trend and so on. Three steps are microscopically and macroscopically used for the regional long-term load forecasting in order to increase the accuracy and practically of the results.

Nowadays, the environmental conservation has become a hot issue. Also the sustainable city issue is recognized as one of the most important tasks to be solved urgently for urban development. Therefore, the current indicator for sustainable city has been analyzed only as a segment of the environmental indicator which is one kind of branch of social indicator. However, considering the degree of pollution and heightened concern, it is time to develop a new and improved framework for the analysis of the sustainable city indicator. This study aims for the development of sustainable city indicator and the examination of practical method for the use of them. Urban sustainable city indicators are based on the "Pressure-State-Response (PSR) framework" which has been adopted by Organization for Economic Cooperation and Development (OECD). The indicators suggested in this study is composed of the following categories: 1. Indicators of natural environment itself, such as land structure (available land use index etc.), bio-species (bio-diversity index etc.), environment resources (water quantity index etc.) 2. Indicators of relationship between man and environment, such as sustainability of using material (recycle of water index etc.), pressure size (pressure index on air etc.), effort of prevention (environmental basic facility index, etc.) 3. Indicators of environmental state, such as landscape and culture (historical & cultural index etc.), environmental pollution (air pollution index etc.) A sustainable city environment is necessary and obtainable, yet its realization seems to be difficult. The urban pollution problems have become more serious than ever before thus requiring much interest. Therefore, this kind of study is meaningful for the establishment of policy objective, and the development and management environmentally sound and sustainable cities.

This paper presents a method of the regional long-term distribution planning considering economic indicator with the assumption that energy demands proportionally increases with the economic indicators. For the practical distribution planning, it is necessary to regional load forecasting, distribution substation planning, distribution feeder planning. Accordingly, in this paper, after performing regional load forecasting considering economic indicator, it is performed distribution substation planning and distribution feeder planning in order by using this result. For accurate distribution planning, it is very important to scrutinize the correlation among the regional electric power demands, economic indicator and other characteristics because distribution planning results may vary depending on many different factors such as electric power demands, gross products, social trend and so on. In this paper, various steps microscopically and macro scopically are used for the regional long-term distribution planning in order to increase the accuracy and practical use of the results

The purpose of this research is to develop evaluation indicators for evaluating the social value of libraries and, for this, first of all, preliminary evaluation indicators were derived by analyzing comprehensively about 60 domestic and overseas papers which researched on the value of libraries. On the basis of the derived preliminary evaluation indicators, 11 experts were selected and the final evaluation indicators were developed by conducting Delphi survey three times. The final evaluation indicators are composed of five evaluation areas, which are the divided areas of the social value of libraries, such as the development of local communities, the linkage of local communities, the improvement of local residents' life quality, the equalization of local residents, and the information services necessary for local communities, 13 evaluation items, and 64 evaluation indicators. In the future, it seems that researches to measure the social value of libraries based on this will have to be conducted.

This papers is to find out the design theory of total healing environment through the studies on the mutually complementary roles of proxemics, which is the objective and numerical design indicator in the analysis of space and the spacial expression theory, which is the subjective and intuitive design indicator. 3 factors in the elements of total healing environment have the following relationship. And 8 behavioral affordance factors in the elements of spatial expression have the following mutual relationships; The physical factor of total healing environment has the relation with the work&study(+) and circulation(+), the psychological factor has the relationship with the rest(-),visual sequence(-),social exchange(+),refreshment(-) and meditation(-). In addition, the social factor of total healing environment has the relation with the circulation(+),social exchange(+) and community(+). And the work&study(+) and rest(-) of the refuge have the relation with the intimate distance and personal distance, the circulation (+) and visual sequence (-) of the flow has the relationship with the social distance. In addition, the social exchange (+) and the refreshment (-) of the prospect have the relation with the near public distance and the community (+) and meditation (-) of the void have the relation with the far public distance. According to the analysis, the cases in 5 children hospital were studied and the characteristics of total healing environment was evaluated for the spatial proxemics.
