BACKGROUND The role of positron emission tomography-computed tomography (PET-CT) for the staging of non-small cell lung cancer (NSCLC) has been well documented, whereas its role for postoperative surveillance after the curative resection of this cancer has not. We prospectively implemented PET-CT in our surveillance protocol for recurrence of NSCLC and(More)
In broadband wireless OFDMA systems where a set of subcarriers is shared among multiple users, the overall system throughput can be improved by a band AMC mode that selects subbands preferential to individual users. As long as channel qualities for the subbands of all users are known a priori, multi-user and frequency diversity gains can be simultaneously(More)
A prevalent underlying theme is the techniques used to control the handover of users as they move between cells, at greater speeds, and with stricter requirements on both the QoS delivered to the user and operational costs associated with a connection. The decision to initiate a handover depends on a number of control variables. Simple estimation of vehicle(More)
In this paper, a packet scheduling algorithm for non-real-time service is considered, with a soft QoS requirements, which allows for degrading the QoS level, e.g., typically the packet delay, whenever necessary, in mobile broadband wireless internet access systems. This is designed to optimally trade off system throughput and delay performance, depending on(More)
Erdheim-Chester disease (ECD) is a rare proliferative non-Langerhans cell histiocytosis of multiple organs with unknown etiology. Around 20% of ECD cases are reported to be associated with lung involvement and there are very few cases manifested solely by nonspecific respiratory symptoms. A 50-year-old woman presented with dry cough and dyspnea for 2 weeks.(More)
This study investigated the adverse health outcomes and urinary heavy metal levels in residents exposed to cement dust, compared to those who were not exposed. A total of 374 residents (276 for the exposed group and 98 for the unexposed group) were surveyed. Participant demographics, health-related behaviors (smoking and drinking), medical history, and(More)
The past several years have witnessed a powerful resurgence of Korean national cinema in terms of both production and popularity. The so-called the ‘renaissance of Korean national cinema’ was stimulated by nationalistic sentiments among Korean audiences just after the financial crisis of 1998. The overwhelming popularity of two films, Shiri (1999) and Joint(More)
