Leaf senescence is a developmentally programmed cell death process that constitutes the final step of leaf development and involves the extensive reprogramming of gene expression. Despite the importance of senescence in plants, the underlying regulatory mechanisms are not well understood. This study reports the isolation and functional analysis of RAV1,(More)
Predicting the preferences of users and providing the personalized services or products based on their preferences are the important issues. However, the research considering users' preferences on context-aware computing is a relatively insufficient research field. Hence, this paper aims to propose an agent-based framework for providing the personalized(More)
Auxin regulates a variety of physiological and developmental processes in plants. Although auxin acts as a suppressor of leaf senescence, its exact role in this respect has not been clearly defined, aside from circumstantial evidence. It was found here that ARF2 functions in the auxin-mediated control of Arabidopsis leaf longevity, as discovered by(More)
As in other countries, type 2 diabetes is major health concern in Korea. A dramatic increase in the prevalence of type 2 diabetes and its chronic complications has led to an increase in health costs and economic burdens. Early detection of high risk individuals, hidden diabetic patients, and improvement in the quality of care for the disease are the first(More)
We investigated an October 2014 outbreak of illness caused by Shigella sonnei in a daycare center in the Republic of Korea (South Korea). The outbreak strain was resistant to extended-spectrum cephalosporins and fluoroquinolones and was traced to a child who had traveled to Vietnam. Improved hygiene and infection control practices are needed for prevention(More)
— In this paper, we propose a mapping and navigation method for mobile robots with low computational resources and limited memory capacity. The proposed navigation method is based on topological mapping of visual features for its compact representation and robustness in localization. In order to improve the localization accuracy and minimize the memory(More)
BACKGROUND The purpose of the current study was to investigate the association of obesity level, physical fitness level, hemoglobin A1c (HbA1c) level and metabolic syndrome (MetS) risk factors among Korean adults. METHODS A total of 557 adults (272 males and 285 females) who underwent medical check-up at local hospital were recruited. In addition to(More)
an outbreak caused by Shiga toxin–producing Escherichia coli O104:H4 was reported in Germany and other countries in Europe. In this outbreak, the number of hemolytic uremic syndrome (HUS) cases has been unusually high (1). As of June 9, 2011, a total of 722 cases of HUS, 19 deaths, and 2,745 cases of enterohemorrhagic E. coli (EHEC) infection were reported(More)
Management of temporomandibular joint (TMJ) ankylosis is challenging for the oral and maxillofacial surgeon because it involves the mouth opening, dentofacial deformity, diet problem, and quality of life. Although surgical techniques to treat TMJ ankylosis have improved, reankylosis is a persistent problem. The temporalis myofascial flap provides good(More)
Our study of risk factors for T. gondii infection was a case-control design to evaluate recent infection, not a cross-sectional study of T. gondii infection prevalence in a population. In our study, case-patients with recent infection were similar in age to T. gondii–negative control-patients, although among women the mean age of case-patients (33 years)(More)
