The purpose of this study was to validate the Korean version of autonomy preference index (K-API) for chronic patients. Participants were 569 chronic patients. Construct validity and reliability of K-API were examined using exploratory and confirmatory factor analysis, and Cronbach's α test. Original API was translated to Korean, and we conducted contents validity test, and pilot test. The K-API consisted of 10 items divided into two domains: (i) Decision making preference (DMP); (ii) Information seeking preference (ISP). K-API explained 53.4% of autonomy preference; the two-factor structure showed an acceptance fit. Cronbach's α was. 77 for DMP, and. 75 for ISP. Validity and reliability of the K-API were established, and this study provides additional evidence for the usage of the API in Asian region.

In For the past few years, query log data has been collected to find user's behavior in using the site. Many researches have studied on the usage of query logs to extract user's preference, recommend personalization, improve caching and pre-fetching of Web objects, build better adaptive user interfaces, and also to improve Web search for a search engine application. A query log contain data such as the client's IP address, time and date of request, the resources or page requested, status of request HTTP method used and the type of browser and operating system. A query log can offer valuable insight into web site usage. A proper compilation and interpretation of query log can provide a baseline of statistics that indicate the usage levels of website and can be used as tool to assist decision making in management activities. In this paper we want to discuss on the tasks performed of query logs in pre-processing of web usage mining. We will use query logs from an online newspaper company. The query logs will undergo pre-processing stage, in which the clickstream data is cleaned and partitioned into a set of user interactions which will represent the activities of each user during their visits to the site. The query logs will undergo essential task in pre-processing which are data cleaning and user identification.

This study was conducted to determine clutch size and habitat usage of Kentish plovers (Charadrius alexandrinus) breeding on Sinja-do lslet in the Nakdong Estuary from 22 April to 12 July in 1995 and from 21 April to 20 June in 1996. The Kentish plover preferred grasslands and damp sands to dry dunes as nesting sites. The difference in hatching success among these microhabitats was attributed to high tides, which washed away many nests on damp sands, and strong winds, which frequently shifted the sand to bury eggs on dry dunes. The main mortality factor in grasslands was predation by magpies Pica pica. Each clutch contained one to four eggs, with a mode of three eggs. Hatching success was highest in two-egg clutches and lowest in one- and four-egg clutches. The mean interval for egg laying was 1.8 days between the first and second eggs and 2.1 days between the second and third eggs. The average incubation period was about 24.2 days.

This thesis on the basis of the "Sasang"(the four classification by the physical constitution) that becomes the focus of the public interest in Korea intends to grasp a color image and serve basic materials for the color usage in the interior design planning. It tries to identify the relationship between physical constitution and color. The color planning for experiment plans to be related to Korean traditional color. Analysis result on color and color image to patterns of interior color shows that the physical constitution in measure difference is bigger than sex among the many image evaluation items. Therefore, the interior color preference of Korean is bright hue and tint such as warm and cool color.

This research aims to analyse the practices adopted by social media users in the Kingdom of Saudi Arabia (KSA), specifically users of Facebook and Snapchat. To collect data from participants, a questionnaire was used, generating 915 responses. The analysis of the data shows a clear preference for Snapchat over Facebook in the KSA, where 89% of the participants have accounts on Snapchat compared to 66% of them with accounts on Facebook. Moreover, the preference for Snapchat over Facebook has been clearly shown in the daily usage of participants, where 83% of those with Snapchat accounts can be described as very active users. They have accessed their Snapchat accounts at least once a day compared to only 15% of Facebook users. Different reasons were provided by the participants explaining the practices they adopted. We believe that such research could help social media applications' designers and policy makers to understand the behaviour of users in the KSA when using social media applications and the rationale behind their behaviour and preferences. This understanding could help improve the performance of current applications and new ones.

The purpose of this research was to find out the preferences in HMUBs for living space in respondents' later life. For this purpose, this research was conducted by social survey research using a questionnaire for those who lived in an urban area around Seoul. The data was collected from November to December, 2005. The results of this research were as follows. Firstly, respondents agreed with living in high rise mixed use buildings in their later life because of convenience. Willingness to move into HMUBs was positive. Concerning preferred physical features, residents preferred living in either lower floors or higher floors because of safety or fine views. Regarding the usage of common space and facilities, they wanted to use them with other generations and preferred 2 bedroom type unit located in a suburban area. Secondly, the preference for living in a HMUB in later life was higher in women respondents than in men. Thirdly, the preference for living in a HMUB in later life was higher in upper floors than lower floors according to property and asset value. As a conclusion, the development of HMUB housing for older people has a bright prospect for urban residents in Korea.

The objective of this research is to investigate the different aspects in which users positively identify with indoor green walls and the influences that it has on usage behaviors. Under the hypothesis that public space users prefer locations with green walls, the effect on their behavior was observed. After installing indoor green walls, behavioral observations and questionnaires were carried out to analyze green wall preferences. The observation experiment was carried out for a total of 8 days in order to see what influences the preferences for of indoor green walls had on usage behaviors and compare a control group with an experimental group that experienced a green wall. The usage time data were put into an SPSS statistics program and used to run an independent sample t-test. The questionnaire was carried out for two days from March 1st to 2nd 2014 after the observation was completed, and was done by 224 users of the two areas. The results from the experiment are as follows. First, comparisons between the total usage time of seats adjoined to partitions in both the green walled area and the partitioned area showed that there was no preference for indoor green walls. Second, the results appeared to show a higher percentage of women users in the green walled area, compared to the original partitioned area. Third, it showed that partitions and plants did not have any influence on seat choices. Fourth, the questionnaire showed preferences for indoor green walls. Out of the 94 people who sat in the partitioned area, 11.7% answered that they wanted to sit in the green walled area, they couldn't due to the lack of available seats. Furthermore, out of the 130 people who sat in the green walled area, 24.6% said they chose the seat because of their preference for the green wall. Although 64.3% of users of the two areas said that they would choose the green walled area if under the same circumstances, the behavior observation did not reflect this.

This study of 322 elementary school children examined the interrelatedness of internet preference, frequencies of internet activities, usage of children's popular internet sites, knowledge of internet sites, and children's reading abilities. Usage of children's popular internet sites and knowledge of internet sites are interrelated with decoding and comprehension. Age, knowledge of internet sites, and sex predicted children's reading abilities. The extent of exposure to various internet activities differentiated children's reading comprehension. Results show that processes of reading text information and multimedia materials through the internet involve not only the skills of reading traditional printed texts but also new reading strategies.

This paper studies six different AHP (Analytic Hierarchy Process) approaches and suggests that the features of the approaches are classified by application circumstances in order to contribute to the applicability and quality usage of the AHP. Our study investigates the hierarchical principles and characteristics of the AHP, and historical debates on the AHP evaluation in which the six approaches have been involved. One of six approaches is an ANP (Analytic Network Process) application that is directly connected to AHP usage. The application differences among the six approaches are validated with a plain example. Then, the four circumstances of AHP applications are classified by two dimensions: the first dimension is whether or not the importance (weights) of criteria is independent of restrictively setting alternatives, and the second dimension is whether or not preference (priorities) of alternatives is independent of adding alternative(s) to or removing alternative(s) from the considering set of alternatives. Then featuring way of weighting criteria is classified. We suggest the distinguishing manners and describe the implications of the AHP application. Finally, we discuss rank reversal and multiplicative AHP.

This survey was conducted to investigate the usage of potato and recognition of glycoalkaloid among residents aged from their teens to over fifties in Daegu city and Gyeongbuk Province. The preferred purchase places for the respondents were traditional markets (41.8%), big discount markets (23.8%), and supermarkets (14.9%), in order. Freshness (52.1%) was the most important criterion followed by size (12.5%), sprout (10.1%) and producing district (6.6%), in order. Most (77.6%) respondents preferred small amount below $2{\sim}3kg$ per purchase. Potato recognition revealed that respondents knew relatively well that potato sprouts contain toxins (M=4.30), that the major potato toxin is solanine (M=3.86) and that potato contains toxins when its color turns to green (M=3.70). However, respondents did not recognized well that the potato peel contains toxins (M=3.00), or that this toxin is chaconine (M=2.48).
