Chronic pain is a widespread problem, especially in the older population, and can affect various aspects of daily living. At a time when it has been acknowledged that the population is increasingly ageing, research regarding the effects of chronic pain on the daily living of older adults is essential. Furthermore, the development of innovative technology is changing the way that much research is being conducted, and can lead to the retrieval of novel information, using a fresh approach. The adoption of this technology in the field of chronic pain research has the potential to examine various aspects of the daily living of older adults living with chronic pain using a different approach to previous research. This study is underpinned by a Critical Realist ontology and Hermeneutic epistemology and follows a Generic Qualitative Research methodology (Caelli, et al., 2003). The aim of the study was not to generalise the findings but to gather a deep theoretical description of the outcomes and offer an explanation of these findings based on an analysis of the multiple research methods used within the study. This study had two main aims and was split into two sections according to the aims. Firstly, Part A of this study aimed to explore a range of day-to-day patterns and experiences of functioning in older adults suffering from chronic pain. Part B aimed to explore the usability, acceptance and experience of the technology used to measure functioning as part of the first aim of this study. Part B also aimed to look at the practicalities the participants were faced with when using the technology. A mixed methods design was used for Part A in which 15 older adults (65+) living with chronic pain (pain >3 months) took part in an in-depth study lasting seven days. As well as the 15 core participants that took part in the study, two older adults (65+) without chronic pain and two younger adults (<65) with chronic pain took part in the study in order to provide some insight into the effects of either pain, or age, on functioning. Part A used four data collection techniques to gather data upon the daily functioning of older adults with chronic pain; the Daily Reconstruction Method diary (Kahneman, Krueger, Schkade, Schwarz, Stone, 2004), the Sensecam (also known as the Vicon Revue, Vicon©), the LifeShirt (Vivometrics Inc) and a semi-structured interview. However, although the LifeShirt was validated, as part of this PhD, and used throughout the study, the gathered data was not analysed due to multiple problems with the data. The Daily Reconstruction Method, Sensecam and the semi-structured interview were each analysed separately before the results of the Daily Reconstruction Method and Sensecam were integrated into the themes derived from the semi-structured interviews. The integrated results led to the development of two themes, each with sub-themes; ‘effect on daily living’ and ‘managing pain and functioning’. The themes from Part A highlighted the way in which pain affected functioning and the modifications to daily functioning as a result of chronic pain. The way in which individuals perceived the management of their own pain and functioning, as well as strategies and assistive devices to manage pain and functioning were also discussed. This study has furthered current knowledge due to the idiographic nature of the study, as well as multiple, novel, data collection tools used, adding additional details to how tasks have been modified, reduced, or terminated. Part B of this study used the Unified Theory of Acceptance and Use of Technology (UTAUT, Venkatesh, et al., 2003), the Flow-State Scale (Jackson & Marsh, 1996) and semi-structured interviews to explore participants’ use of both the Sensecam and LifeShirt. The questionnaires and interviews were carried out with all of the individuals that carried out Part A of this research. From the semi-structured interviews two main themes were reported, each with sub-themes; ‘expectations and experiences’ and ‘awareness of equipment’. Two concepts developed from the themes within Part B that were specific to the participants’ experiences of wearing wearable technology in this study, as opposed to ‘typical’ non-wearable technology; specifically, the importance of design and the importance of others. Both of these overarching concepts affected the expectations of the technology, the experiences of using the technology, as well as the awareness of the technology during use. Furthermore, both concepts will remain and are long-lasting, despite the development of the technology in this field, but there are specific details that are contemporary and are specific to either the Sensecam or the LifeShirt as used in this study.

本創作主要為基於習慣、記憶、生命記錄理念而開發的應用程式，希望以眾多的行動應用為基礎，藉由本創作主動提醒的機制，讓使用者更容易回想過去的記憶、再次體驗重遊的經驗和感受，並試圖了解使用者在經由提醒下的影響。 本創作為實作於iPhone上App，使用Objective-C程式語言撰寫，稱之為「iRemind」。實驗結果的三e指標、介面使用經驗皆有達到實驗所設定的目標，結果發現，大多受測者滿意本創作的設計與功能，也滿意本創作提出主動提醒的概念，認為有助於回憶事件，而且覺得是有趣的。但頻繁的提醒記憶會影響使用者在體驗過程的愉悅性，在主動提醒機制上，需要符合使用者需求進行相關設計，因此最後本文有提出幾項建議與設計作為參考。 / This research developed an application based on the concept of people’s habits, memories, and life-logs. We not only hoped that users can recall their memories or re-experience the feeling of their travels easily by the mechanism of active reminder, but also wanted to realize the effect on users. The system was implemented on iPhone, so we used Objective-c as primary language. And we named it “iRemind”. The “3-E indicators” of the experiment results and interface of user experience all achieved the desired goal. Most of users approved iRemind’s design, function and the concept of the active reminder, and they believe it also helps them recall past events. Besides, they think it’s interesting. But when it reminds too frequently, the enjoyment of user experience will be reduced. Therefore, the mechanism of active reminder design should consider users’ needs. In the end, we proposed some suggestions for future improvement.

Tremendous advances in wearable computing and storage technologies enable us to record not just snapshots of an event but the whole human experience for a long period of time. Such a \life-logandamp;quot; system captures important events as they happen, rather than an after-thought. Such a system has applications in many areas such as law enforcement, personal archives, police questioning, and medicine. Much of the existing eandamp;reg;orts focus on the pattern recognition and information retrieval aspects of the system. On the other hand, the privacy issues raised by such an intrusive system have not received much attention from the research community. The objectives of this research project are two-fold: andamp;macr;rst, to construct a wearable life-log video system, and second, to provide a solution for protecting the identity of the subjects in the video while keeping the video useful. In this thesis work, we designed a portable wearable life-log system that implements audio distortion and face blocking in a real time to protect the privacy of the subjects who are being recorded in life-log video. For audio, our system automatically isolates the subject's speech and distorts it using a pitch- shifting algorithm to conceal the identity. For video, our system uses a real-time face detection, tracking and blocking algorithm to obfuscate the faces of the subjects. Extensive experiments have been conducted on interview videos to demonstrate the ability of our system in protecting the identity of the subject while maintaining the usability of the life-log video.

PHRサービス「ポケットカルテ」に集積された個々の住民の生涯の健康医療福祉介護履歴情報は、当該個人のLife-Logといえることが判明し、従来の医療費に加えて、健康維持や「未病」対応のための消費の総和を新たな指標「健康費」と定義した。現在の医療経済施策基盤である国民医療費の上位概念となる「健康費」を最適化することは、医療の質を向上しつつ、国民医療費を適正化し、国民皆保険の維持に寄与すると思われる。 / The big data of the life-long history information in health care and welfare care of an individual resident stored in the PHR service "Pocket Karte", has been found to be the Life-Log of the resident. So, I have defined a new index "Health Care Fee" as the sum of consumptions for health maintenance and the "pre-disease" care in addition to the conventional medical costs. It is believed that to optimize the "Health Care Fee", the broader concept of the Estimates of National Medical Care Expenditure as the basis for medical economic policy currently, is to contribute to improve the quality of medical care, and to optimize the Estimates of National Medical Care Expenditure, and to maintain of universal health insurance system in Japan. / 博士(政策科学) / Doctor of Philosophy in Policy and Management / 同志社大学 / Doshisha University
