Purpose The purpose of this study is to explore the pattern of user response and it's duration time through social media content response analysis. We also analyze the characteristics of content quality factors which are associate with the user response pattern. The analysis results will provide some implications to develop strategies and schematic plans for the operator of regional marketing on the SNS. Design/methodology/approach This study used mixed methods to verify the effects and responses of social media contents on the users who have concerns about regional events such as local festival, cultural events, and city tours etc. Big data analysis was conducted with the quantitative data from regional government SNSs. The data was collected through web crawling in order to analyze the social media contents. We especially analyzed the contents duration time and peak level time. This study also analyzed the characteristics of contents quality factors using expert evaluation data on the social media contents. Finally, we verify the relationship between the contents quality factors and user response types by cross correlation analysis. Findings According to the big data analysis, we could find some content life cycle which can be explained through empirical distribution with peak time pattern and left skewed long tail. The user response patterns are dependent on time and contents quality. In addition, this study confirms that the level of quality of social media content is closely relate to user interaction and response pattern. As a result of the contents response pattern analysis, it is necessary to develop high quality contents design strategy and content posting and propagation tactics. The SNS operators need to develop high quality contents using rich-media technology and active response contents that induce opinion leader on the SNS.

The Affordance, discussed in the theory of ecological perception of environmental psychology, is the concept of perception that deals with inter-relationship between environment and human. It is a theory seeking for gradual evolution, with the change of user experience behavior and the space, by getting feed-backs from the analysis of perception of characteristics of 3-dimensional space and the user as moving entity. Although there has been many attempts to define the Affordance and apply its concept to the architecture, now there's a need to identify the Affordance in the real architectural space, represent Affordance of space and the user inter-relationship in the architecture and apply its design specifically, Thus, the purpose of this study is to present the methodology of applying Affordance in architectural space design by identifying the Affordance of space concept of human experience behavior in the architectural space and analyze its recognition process.

Objective: The purpose of this study was to investigate major factors influencing adoption of smartphone to promote its use by older adults. Background: Despite increasing proportion of elderly people and elderly market, the proportion of elderly smartphone user is still relatively small compared to whole smartphone users. Thus, we need to find out major factors influencing adoption of smartphone to increase proportion of elderly smartphone users. Method: Seven major factors were extracted from 36 survey questions using factor analysis. Regression analysis was also applied to determine specific factors affecting intention of use based on user versus non-user of smartphone, age, gender, and educational background. Results: As results of factor analysis and regression analysis, major factors influencing adoption of smartphone for elderly users were significantly different according to gender, age, educational background based on smartphone users or non-users. Conclusion: The result of this study identified major factors influencing adoption of smartphone for the elderly and provided basic information related to adoption of smartphone according to elderly people's characteristics. Consequently, we can expect to reduce the information gap and to improve quality of life for the elderly. Application: The development and marketing strategy could be applied differently based on the factors influencing adoption of smartphone. It is also possible to develop a prediction model for smartphone adoption according to elderly users' characteristics.

he objective of this study was to investigate home network systems presently applied in multi-housing complexes and resident's usage to improve the utilization of these systems and services as well as maintenance methods. Subjects were 27 housing complexes equipped with home network systems in west Pangyo area. The investigation methods of communal network systems were observed and photographed. Unit systems were investigated through photography, interviews, and observation focusing on the utilization of Wall-Pads by visiting one unit of each housing complex. The results are as follows: (1) Most housing complexes that we investigated were built with high-grade IT infrastructure. Also, remote meter reading, electronic security, vehicle access, and building access systems were established. Wall-Pads with similar functions were installed in 23 housing complexes, excluding private rental housing complexes. (2) Even though people were well aware of the need for common systems within their housing complexes, only 10~20% of Wall-Pad menus were used. (3) Low utilization rates of home network stem from Wall-Pad menus which were user-unfriendly, and a lack of user training for the complex's common system and unit system. Therefore, to promote active use of home network systems, the systems must be diversified in accordance with user characteristics. In addition, the Wall-Pad menus should be reorganized to be user-friendly.

In web environment, we accept most of useful information visually. Icon is a channel through which we explore information, and we need icon design to deliver information clearly and quickly to users who accept information visually. Studies on icon have been carried out vigorously according to system environment, styles and characteristics of users. This study is on the metaphor icon, and judging from the characteristics of metaphor icon, it is by the phenomena of user's association of ideas. Divide metaphor and simile and analyzed metaphor icon that is searched in World Wide Web to distinguish similarity in metaphor icon special qualify, And I clarified the present condition of cognition by questionnaires asking people if they recognize the function. I also clarified if elements of icon design influence the level of user's cognition by visually comparing icons. The result of comparative analysis showed that different elements make different level of user's cognition, and to objectify it more, I made up questionnaires about elements of icon design and proved it again. To summarize the result of this study, the similarity between function and elements of design increases the level of recognition of metaphor icon proportionally. To improve user's cognition, I suggest designing with elements which materialize functions.

Previous research on data extraction and integration for data warehousing has concentrated mainly on the relational DBMS or partly on the object-oriented DBMS. Mostly, it describes issues related with the change data (deltas) capture and the incremental update by using the triggering technique of active database systems. But, little attention has been paid to data extraction approaches from other types of source systems like hierarchical DBMS, etc. and from source systems without triggering capability. This paper argues, from the practical point of view, that we need to consider not only the types of information sources and capabilities of ETT tools but also other factors of source systems such as operational characteristics (i.e., whether they support DBMS log, user log or no log, timestamp), and DBMS characteristics (i.e., whether they have the triggering capability or not, etc), in order to find out appropriate data extraction techniques that could be applied to different source systems. Having applied several different data extraction techniques (e.g., DBMS log, user log, triggering, timestamp-based extraction, file comparison) to S bank's source systems (e.g., IMS, DB2, ORACLE, and SAM file), we discovered that data extraction techniques available in a commercial ETT tool do not completely support data extraction from the DBMS log of IMS system. For such IMS systems, a new date extraction technique is proposed which first creates Index database and then updates the data warehouse using the Index database. We illustrates this technique using an example application.

This paper reports on the results of a questionnaire survey on actual conditions of sleep environment, sleep problems and sleep patterns in bedroom of house. The objectives of survey are: 1) classifying Korean people into several groups by sleep environment condition, sleep problem and life pattern, 2) describing the characteristics of user groups, and 3) searching needs of support for each user group. Despite of several studies about sleep condition that researched in advance, they weren't considered about user's respective characters. So it seems necessary for more studies about users' needs, and segment users to grasp their each detail needs. Therefore, this study conducted questionnaire survey gathering relevant information to classify user groups and to investigate the current bedroom condition. In the result, 702 respondents were divided into six clusters by extracted eight factors. Four clusters of them had some problems for sleep, so it could be seen that they need environmental solution for their good sleep. As the further objective, it will be connected to develop the good sleep system.

According to the 2005 Korean census, the 65 and over population now exceeds 9.5% of the total population and is growing rapidly. Meeting elderly environment and care needs of this rapidly growing segment of the population becomes a major challenge for public policies and planners. Since great deal amount of elderly will reside in their houses, aging in place concept becomes important. For the success of aging in place, the quality of individual house unit, community support systems, and quality of senior center of the community are crucial. Since elderly environments and facilities serve not only medical and/or care programs but also social activity program in aging society, senior centers need to promote social activities and other care programs. The purpose of this study is to analyze characteristics of environmental affordance of a well received senior center in Tokyo, Japan. In order to analyze the characteristics, Murtha & Lee user benefit criteria and Lawton's environmental affordance approaches were used. As results, design characteristics and interior elements which provide environmental affordance were enumerated by type of space. Based on needs and user benefit criteria, those features were analyzed. This study shows design characteristics, elements, and attributes which are well received and utilized by elderly users.
