The ubiquity of location enabled devices has resulted in a wide proliferation based applications and services. To handle the growing scale, database management systems driving such services (LBS) must cope with high insert rates for updates millions devices, while supporting efficient real-time analysis on latest location. Traditional DBMSs, equipped multi-dimensional index structures, can efficiently spatio-temporal data. However, popular open source relational are overwhelmed by insertion...

Database systems serving cloud platforms must serve large numbers of applications (or tenants ). In addition to managing with small data footprints, different schemas, and variable load patterns, such multitenant minimize their operating costs by efficient resource sharing. When deployed over a pay-per-use infrastructure, elastic scaling balancing, enabled low cost live migration tenant databases, is critical tolerate variations while minimizing cost. However, existing databases---relational...

Severe Candida esophagitis (CE) may lead to development of strictures, hemorrhage, esophagotracheal fistula, and a consequent decrease in quality life. Although the severity CE has been classified based on macroscopic findings endoscopy, clinical significance remains unknown. The aim study was elucidate predictive factors for endoscopic CE. Patients who underwent upper endoscopy answered questionnaires were prospectively enrolled. Smoking, alcohol, human immunodeficiency virus (HIV)...

We are living in a cyber-physical-social environment with variety of lifestyles and values.Living support has become important such diverse society.Owing to the ability collect large amount personal data or life logs environment, it is now possible for us provide based on analysis.Moreover, analyzing can facilitate deep understanding an individual.In this study, we focus provision cyber-enabled well-being oriented daily individual analysis.Three categories identified from individual's...

Endoscopic diagnosis of amebic colitis can be difficult because its appearance may mimic other forms colonic disease. The aim this study was to identify predictive endoscopic findings for colitis. Patients with suspected based on distinctive such as aphthae or erosions, ulcers, exudates, a bump, were included in the study. A total 157 patients selected, 50 whom had sensitivity and specificity that significantly associated were: cecal lesions (80 % 54 %), multiple number (96 29 presence...

Recently, massive data management plays an increasingly important role in analytics because access is a major bottleneck. Data skipping promising technique to reduce the number of accesses. partitions into pages and accesses only that contain be retrieved by query. Therefore, effective partitioning required minimize page However, it NP-hard problem obtain optimal given query pattern distribution.

The prebraking-related actions typically studied are the main maneuvers carried out to avoid collision. Especially for those braking taken when turning or parking, accidents often occur because of human errors such as incorrect choice pedal. However, regarding these daily braking-related driving behaviors, effects driver characteristics, experience and gender, on prebraking behaviors remain unknown. Therefore, defining movements a driver's body before his her foot touches brake pedal, this...

In the post-COVID-19 pandemic era, many countries have launched apps to trace contacts of COVID-19 infections. Each contact-tracing app (CTA) faces a variety issues owing different national policies or technologies for tracing contacts.

Garlic constituents, the volatile oil, alliin, S-allylmercaptocysteine (ASSC) and S-methylmercapto-cysteine (MSSC) were subjected to assay for their antihepatotoxic activity using in vitro vivo liver damage models. Marked inhibitory was found with ASSC MSSC carbon tetrachloride (CCl4)- galactosamine (GalN)-induced cytotoxicity primary cultured rat hepatocytes as model systems. exhibited a remarkable action alliin showed tendencies elicit protective actions GalN-produced lesion rats. The oil...

The recent development of commodity 360° cameras have enabled a single video to capture an entire scene, which endows promising potentials in surveillance scenarios. However, research omnidirectional analysis has lagged behind the hardware advances. In this work, we address important problem action recognition topview videos. Due wide filed-of-view, videos usually multiple people performing actions at same time. Furthermore, appearance are deformed. proposed framework first transforms...

Owing to the aging of rural population in hilly and mountainous areas Japan, mowing on narrow ridges steep slopes is done manually by elderly-individuals over 65 years age. Studies have shown that many accidents occurred during were caused workers' unstable posture, especially when surfaces where there a high risk falling. It necessary analyze body movements workers elucidate elements related falls. Therefore, this study, based high-precision motion-capture device series experiments with...

In the mountainous areas of Japan, weeds on slopes terraced rice paddies still need to be cut by elderly manually. Therefore, more attention should given maintain proper postures while performing mowing actions (especially pre-cutting actions) reduce risk accidents. Given that complex can decomposed into different sub-actions, we proposed a joint angular calculation-based body movement analysis model based Hilbert–Huang transform analyze actions. We found two most important sub-actions were...

The world has become an aging society with exponentially increasing social security benefit expenditure and nursing care costs. To help solve these issues challenges, utilization of advanced ICT is highly expected to allow more elderly people remain independent for their proactive participation irrespective age. In this study, we propose a human-centric safe secure framework ubiquitous living environments (Ubi-Liven) the towards seamless integration cyber-enabled holistic support system...

In this paper we propose a new algorithm for finding the frequent routes that user has in his daily routine, our method build grid which map each of GPS data points belong to certain sequence. (We consider sequence conforms route) then carry out an interpolation procedure probabilistic basis and find more precise description user's trajectory. For trajectory edges were crossed, with crossed create histogram bins denote frequency value number times edge was user. We select K most combine them...

Abstract A color is a powerful tool used to attract people’s attention and entice them purchase product. However, the way in which specific influences selection role of their eye movements cultural factors this process remain unknown. In study, delve into problem, we designed an experiment determine influence colors on product preferences by using eye-tracking device, intending identify factors. Based experimental data, detailed path model was built describe effect evaluations integrated...

Due to the declining population and aging of farmer in hilly mountainous areas Japan, it is necessary for elderly carry out mowing work on ridges slopes, which traditionally regarded as heavy labor part paddy farming. One most important causes these accidents an incorrect posture; therefore, identify effective safe working patterns during inclined plane mowing. In this paper, we designed implemented a set experiments terraced field area Hiroshima collect information body motion experienced...

Since loitering is a suspicious behavior that often leads to abnormal situations, such as pickpocketing and terrorist attacks, its analysis attracts increasing research attention. In this paper, we present AntiLoiter, practical discovery system for surveillance. AntiLoiter can efficiently discover candidates from longtime videos across multiple cameras. Most of existing systems mainly focus on how detect or identify loiterers by tracking techniques. However, the difficulties tracking-based...
