As scenario-based design is expanded to various fields of design, it is introduced to HCI(Human Computer Interaction) in order to figure out user information & tasks. However, scenario based design methods that is focused on collecting scenarios regarding users'needs, is mainly utilized conceptual design stage for system itself. There is a gap between users'need scenarios to interface design of HCI system. In this study, web survey is suggested as scenario based interface design method in order to connect scenario collecting to task specification and to menu structure design of home-network controller. The degree of users'need for specified tasks was verified to various kinds of users through web survey and it decideddepth and order of menu structure. Tasks also was categorized to situation mode and users can make their own menu structure by selecting menu contents or even mode itself, because degrees of need for specified task situation were varied by lifestyle of user group. Finally, it is found that web survey method can be applied to collect and database various scenarios of. various users when a questionnaire is well designed for collection.

According to the increasing use of information in the mobile web environment, web information techniques previously developed considering only a specific platform become unable to use. Such techniques need to be replaced by the web standard techniques guaranteeing interoperability and to develop a new graphic user interface required in the mobile web environment. Based on such backgrounds, this paper surveyed the standards for implementing web geographic information system(GIS) service considering mobile and desktop environments. Based on the survey results, a GIS system configured with open source is designed and web mapping clients based on ExtJs are implemented for mobile and desktop environments. For the purpose of coping with the new web standard environment, the methods and prototype system suggested and implemented in the paper can be used as a case study to implement a GIS in the use of mobile and desktop environments.

Background: Medically unexplained symptoms (MUSs) are common in primary care. Atpresent, there are no proven, comprehensive treatments available in primary care forpatients with MUSs. However, MUS has parallels with "subhealth" or Mibyeong from tradi-tional East-Asian medicine, and thus, Mibyeong interventions could be effective in treatingMUS. Unfortunately, studies on Mibyeong and its intervention methods are relatively rare.Methods: We administered a web-based survey to 17,279 Korean medicine (KM) practitionersregistered with the Association of Korean Medicine. The response rate was 4.9% (n = 849).Based on the responses received, we assessed how much they agreed with concepts relatedto Mibyeong on a 7-point scale from "do not agree" to "strongly agree." Respondents werealso asked to indicate how frequently they encountered various subtypes and patterns ofMibyeong, and how frequently they use listed intervention methods.Results: Data from 818 respondents were analyzed after excluding those with no clinicalexperience. On average, respondents were male general practitioners aged between 30 yearsand 49 years, working or living in metropolitan areas such as Seoul, Incheon, and Gyeonggi-do. Responses did not differ by demographics. Respondents generally thought that Mibyeongreferred to subjective or borderline findings without certain disease, and that Mibyeong hasvarious subtypes and patterns. Subtypes included fatigue, pain, and digestion problems; pat-terns were either deficiencies (e.g., qi, blood, and yin deficiency) or stagnations (e.g., liver qidepression and qi stagnation). Decoction was the most frequently used type of interventionfor Mibyeong of all items listed, followed by acupuncture and moxibustion. Patient educa-tion was also recommended, suggesting healthy eating, promoting healthy environment,and exercise.Conclusion: We were able to provide preliminary results on KM practitioners' recognition ofand interventions for Mibyeong, but further research is needed to develop a detailed defi-nition of Mibyeong and its myriad subtypes and patterns, and evaluations of the efficacy ofMibyeong interventions.
