Before global SNS services, such as Facebook and Twitter, were introduced in Korea, Cyworld monopolized the Korean SNS market. However, Cyworld was left behind because it maintained a closed system, which no longer satisfied users. KakaoTalk, a popular Korean mobile messaging application has allowed the messenger itself to become a platform for various services including SNS. KakaoStory began as a photo-based SNS service; by integrating with KakaoTalk's profile pictures, it has become the most popular SNS in Korea. This study focuses on the usage patterns of SNS users to analyze how KakaoStory became one of the most popular SNSs in Korea. In particular, we have examined the differences in usage patterns between KakaoStory and Facebook, and the primary reasons why Korean users select one of these two social networking sites instead of the other. We conducted an exploratory comparison between KakaoStory and Facebook, specifically focusing on the usage patterns and motivations of both sets of users. We also analyzed how the different usage motivations linked to these two social media networks have influenced usage patterns. © 2016 Elsevier Ltd. All rights reserved.

This paper introduces a new outdoor localization method for practical application to guide robots. This method uses only encoder data from the robot's wheels and non-inertial sensors, such as GPS and a digital compass, to guarantee ease of use and economy in real world usage without cumulative error. Position and orientation information from DGPS (Differential Global Positioning System) and a digital compass are combined with encoder data from the robot's wheels to more accurately estimate robot position using an extended Kalman filter. Conventional robot guidance methods use different types of fusion that rely on DGPS. We use a very simple and consistent method that ensures localization stability by using the validation gate to evaluate DGPS reliability and digital compass data that can be easily degraded by various noise sources. Experimental results of the localization are presented that show the feasibility and effectiveness of the methods using a real robot in real world conditions.

Aim: When interpreting genetic patterns across a landscape it is surprisingly difficult to disentangle the effects of landscape connectivity from those of species biology. Here, the spatial distributions of genetic variation of two sympatric elephant-shrew species, the western rock elephant-shrew (. Elephantulus rupestris) and the round-eared elephant-shrew (. Macroscelides proboscideus), are determined and compared. We selected these species because they have similar biologies but differ markedly in habitat use, the rationale being that differences in their genetic structure should be a result largely of landscape variables directly or indirectly affecting dispersal rather than of the biology of the species. Location: South Africa and Namibia. Methods: Mitochondrial sequence data (control region and cytochrome b) were used to describe the phylogeographic structure of these elephant-shrew species across their distribution. To determine whether genetic variation is significantly structured, spatial analyses of molecular variation were performed. Isolation-by-distance versus alternative patterns of genetic structure was investigated using a Mantel test. Results: Our analyses indicated an overall structured genetic profile for E. rupestris, a species closely associated with rocky outcrops. This was in contrast to a pattern mostly of isolation-by-distance across the distribution of M. proboscideus, a species found on gravel plains. Main conclusions: Specific landscape features will differentially affect gene flow (both historical and current), and therefore also the spatial genetic structure, of species with markedly different habitat requirements. The genetic profiles for the two species included here support predictions based on the connectivity of their respective occupied habitats. The results also support the more general prediction that species with a naturally clustered distribution (such as E. rupestris) should have a more structured genetic pattern than those having a more continuous distribution (. M. proboscideus). © 2009 Blackwell Publishing Ltd.

Background: In vivo length change behavior of native medial patellofemoral ligament (MPFL) fibers throughout the range of knee motion has not been reported in vivo. Purpose: To measure the length changes of various fibers of the MPFL and to determine their length change patterns during in vivo passive knee flexion. Study Design: Descriptive laboratory study. Methods: The right knees of 11 living subjects were scanned with a high-resolution computed tomography scanner at 0°, 30°,60°, 90°, and 120° of knee flexion, and 3-dimensional (3D) models were constructed using customized software. Five patellar points were determined: 20% (point 20), 30% (point 30), 40% (point 40), 50% (point 50), and 60% (point 60) from the superior pole of the patella. The Scho° ttle femoral point (point F) was marked on a translucent 3D model of a true lateral view. Five virtual fibers connecting these points on the 3D knee model were created, and the lengths of various fibers were digitally measured. Results: The average length changes were 9.1 ± 2.5 mm in F20, 9.1 ± 2.5 mm in F30, 8.1 ± 2.6 mm in F40, 6.9 ± 2.4 mm in F50, and 6.9 ± 1.7 mm in F60. There were significant differences in length changes of these 5 fibers (P<.001). The lengths of 2 superior fibers (F20 and F30) increased as the knee flexed from 0° to 30° and decreased as the knee flexed over 30°. The lengths of a middle fiber (F40) and an inferior fiber (F50) increased from 0° to 30°reached a plateau from 30° to 60°, and then decreased from 60° to 120°. F60 showed an increase from 0° to 30°and then a plateau pattern from 30° to 90°, followed by a decrease during further flexion. Conclusion: Superior fibers exhibited their maximum lengths at low flexion angles, and inferior fibers exhibited their maximum lengths at midflexion angles. The MPFL is a complex of functionally various fibers with some taut and others slack over the whole range of knee motion. Clinical Relevance: The results for lengths and length change patterns of various MPFL fibers are expected to serve as a theoretical background for anatomic double-bundle MPFL reconstruction. © 2014 The Author(s).

Chronic Illness | Year: 2010

Objective: The purpose of this study was to examine the role of spirituality in the self-management of chronic illness among older women with chronic conditions. Methods: A sample of 41 African-American and non-Hispanic White women, of age 66 and older, participated in the process of self-care study. Data were collected from semi-structured interviews and analysed for common themes using the Grounded Theory method. Results: Audiotaped and transcribed interviews identified four categories that emerged to suggest the influence of spirituality in behavioural change and disease management: (1) God's involvement in illness management; (2) prayer as a mediator; (3) spirituality as a coping mechanism; and (4) the combination of conventional and spiritual practices. Discussion: Older women with various chronic illnesses defined in a broad, holistic way, and the findings suggest that spirituality played a part in documenting the self-management process. Knowledge of spirituality and the role it plays in illness management may assist public health gerontologists in designing effective and culturally appropriate self-management programmes. © 2010 The Author(s).

The ERNEST European Research Network on Sustainable Tourism project will address the issue of sustainable development in tourism through coordination and collaboration among regional research programmes. ERNEST will be a horizontal ERA NET action, not directly linked to one specific cooperation theme but with much European added value. The overall objective is to develop and strengthen a framework for coordinating regional research programmes on sustainable tourism. Within this platform regions will share and build on research work already underway at regional level, making it more productive and efficient through exchange and planning and implementation of joint activities. The specific objectives are as follows: identify and exchange information and knowledge on research programmes that regions wish to coordinate; identify within the research programmes elements related to social dialogue (participative processes for programming including all relevant stakeholders) and measurement of tourism impact; define and prepare joint research activities on tourism research; implement joint activities in these fields according to common needs, particularly concentrating on training, exchange and evaluation at an interregional level; fund joint interregional research on sustainable tourism through joint calls; promote productive cooperation and collaboration in research both in terms of interregional cooperation and cooperation at regional level, including public private partnerships; allow partners to define together long-term and ambitious strategies in line with the European Union policy of sustainable development that each region could not easily reach on its own.

The present study explores the links between personality traits and motivations to play online games. We identified the underlying dimensions of motivations to play online games, examined how personality traits predict motivation, and investigated how personality traits predict online gaming behavior (i.e., playing time and preference for game genres). Factor analyses identified five motivational factors: relationships, adventure, escapism, relaxation, and achievement. The regression analyses indicated that two personality traits, extraversion and agreeableness, predicted various motivations; however, personality traits did not affect the playing time and game genre preference. © Copyright 2011, Mary Ann Liebert, Inc.

This study examines the relationship between attribute performance of a restaurant and customers' positive and negative word of mouth (WOM). We present an analysis of 168,262 customer reviews, which consist of an overall rating of a dining experience, ratings of food, physical environment and employee service, and real expenditure for a meal, totally covering 1,542 Chinese restaurants on a restaurant guide website. The results indicate that the performance of attributes has an asymmetric impact on positive and negative WOM for the restaurant industry as well as for low-end and mid-to-high-end restaurants. Our results also show that, in most cases, there is a combined effect of two attributes on both positive and negative WOM. © 2012 Asia Pacific Tourism Association.

This study is to determine the impact of the ICT industry ofthe economic aspects - though it occupies a significant percentage of the global economy, the ICT industry has been largely unnoticed in other industrial researches in the meantime. In other words, from the perspective of a single country's ICT industry, this study identifies the global ICT industry's latest trends and proposes a strategy through the relevance between the global ICT industry environment and economic indicators in a macroscopic point of view. This study determines the causal relationship between GDP and recent ICT trade due to theglobalization of the ICT industry and derives a strategy for GDP increase. The results of this study suggest two important points: (1)the ICT industry is experiencing specialization through the selection and focus within the global economic environment to ensure the country-specific ICT industry and for increase in GDP;(2) the fusion service capacity needs to be expanded through ICT business-to-M&A guided, and national focus on fundamental technology in the ICT industry are major strategies. © Research India Publications.
