Recent developments of information technologies are leading the advent of the era of ubiquitous healthcare, which means healthcare services at any time and at any places. The ubiquitous healthcare service needs a wearable system for more continual measurement of biological signals of a user, which gives information of the user from wearable sensors. In this paper, we propose a wearable context aware system for ubiquitous healthcare, and its systematic design process of a ubiquitous healthcare service. Some wearable sensor systems are introduced with Zigbee communication. We develop a context aware framework to send information from wearable sensors to healthcare service entities as a middleware to solve the interoperability problem between sensor makers and healthcare service providers. And, we propose a systematic process of design of ubiquitous healthcare services with the context aware framework. In order to show the feasibility of the proposed system, some application examples are given, which are applied to remote monitoring, and a self check service.

Purpose The purpose of this paper is to investigate gender differences in motivations to use flexible work arrangements (FWAs) in Korea. Design/methodology/approach Based on a literature review on theory of planned behaviour (TPB), this study considers four motivational factors that influence the intention to use FWA: motivation for personal life, motivation for productivity, peer behaviour and concerns about career disadvantages. Survey response data drawn from 92 male and 105 female Korean workers were used to analyse differences by gender. Findings As for the male respondents, all four motivational factors have a significant effect on the intention to use FWA. However, in the female respondents, the effects of concerns about career disadvantages on the intention to use FWA are not significant. The results of gender differences analysis show that significant difference was not found in the effect of motivation for personal life on the intention to use FWA while the other three motivational factors have significant differences by gender. Research limitations/implications In this research, basing its conceptual background on TPB, a novel approach is taken by introducing motivational factors as the antecedents of intention to use FWA. This is a more systematic view on individuals’ behavioural mechanism relating to the intention to choose FWA. It is also meaningful in that this study looks at the intention to use FWA from a broader perspective by suggesting gender differences as critical analysis criteria given the uniqueness of Korean labour market. Practical implications For an effective operation of FWA, it is important not only to launch a flexible working programme itself, but also to ensure that the users are properly understood and fairly evaluated. Originality/value Considering the motivations of utilising FWA from various angles will contribute to coming up with various measures to raise the use and effectiveness of FWA.
