The purpose of this study is to comprehend the trend of digital experience centers' development direction and to find out the types of experiences, the characteristics of interaction and the attribute of contents by selecting 4 digital experience centers opened from 2008 to 2018. The types of digital experiences are operation, sensibility, reaction and induction based on precedent studies. The types of interaction are operation, touch and sensor. The attributes of contents are game, play and education. The result shows that the ratio of operation experiences is gradually higher. In the types of interaction, the trend is switching to operation and touch. The offer of experience activities by play type is getting higher. This study is intended to help create an empirical interaction of the content of the children's digital experience centers that will be deployed in the future.

The purpose of the paper is to empirically investigate the role of human capital and labour market conditions in the growth process. To do so, cross-sectional data for 3062 counties across 50 states of the US. Firstly, findings from the empirical estimation suggest income convergence among US counties. Secondly, the stock of human capital appears to have the growth enhancing effect while education expenditures turn out to retard economic growth. Thirdly, it is found that the unemployment rate would have a negative association with regional growth whereas the net migration rate is likely to have a positive relationship with growth. Once the sample counties are divided into both the poor group and the rich group, finally, such main empirical results overall remain unchanged and statistically significant.

Collaborative filtering has been popular in commercial recommender systems, as it successfully implements social behavior of customers by suggesting items that might fit to the interests of a user. So far, most common method to find proper items for recommendation is by searching for similar users and consulting their ratings. This paper suggests a new similarity measure for movie recommendation that is based on genre interest, instead of differences between ratings made by two users as in previous similarity measures. From extensive experiments, the proposed measure is proved to perform significantly better than classic similarity measures in terms of both prediction and recommendation qualities.

The new service of Korean public library, ASK_a service model suggests a new management practice in collaborative digital reference services. The model has three functions: input transaction, process transaction, and output transaction. The best form for input is the web form. The best form for process is a model with a hybrid type of public libraries(hierarchical and lateral type). The output suggests the archiving policy for gathering the query-answer data. The core of this model is providing an advanced information service to its users through cooperation with public libraries and external manpower.

It is generally accepted that classification accuracy is affected by the number of learning documents, but there are few studies that show how this influences automatic text classification. This study is focused on evaluating the deviation-based classification model which is developed recently for genre-based classification and comparing it to other classification algorithms with the changing number of training documents. Experiment results show that the deviation-based classification model performs with a superior accuracy of 0.8 from categorizing 7 genres with only 21 training documents. This exceeds the accuracy of Bayesian and SVM. The Deviation-based classification model obtains strong feature selection capability even with small number of training documents because it learns subject information within genre while other methods use different learning process.

Recently, most of computing technology is based on web. Therefore, the users register web services or needed resources, and they can find and use the registered item. These services can be used alone or can be used in combination. When the item is used in combination, the ordering and association of service is important, and an ontology that defined association of services is required. In this paper, we define association of services based on ontology, and propose a method that can be used by services integration. The proposed method provides an efficient retrieval service by compositing the ontology with the service area and data association area.
