While several studies have compared lexical bundle (LB) usage across academic written texts, few have controlled for semantic context, which inevitably affects the usage of bundles. This study examines LBs in the texts of BBC news articles and TED talks in one semantic domain (i.e., global business). It first compares the use of LBs identified in BBC written news articles and TED talks, and then further explores how the LBs are embedded in context. The results show significantly different types of discourse functions and structures to be characteristic of each corpus. The BBC news corpus shows written features including referential expression bundles and phrasal bundles embedded in multiple PPs, while the TED talks rely heavily on features of spoken genres such as stance expression bundles and clausal bundles. Yet both corpora share several features typical of academic written genres. In addition, the findings show that the structures in which the LBs are embedded serve different syntactic roles in each corpus. The finding of differences in spoken and written discourse conventions in the shared semantic context of global business has pedagogical applications for business-related courses at the university level as well as English for Academic Purposes courses.

The Prevalence of Human Papillomavirus Infection in Korean Non-Small Cell Lung Cancer Patients

Human papillomavirus (HPV) infection is a co-carcinogen of lung cancer and contributes to its pathogenesis. To evaluate the prevalence of HPV infection, polymerase chain reaction (PCR) was employed to detect HPV 16, 18, and 33 DNA in tumor tissues of 112 patients with non-small cell lung cancer (NSCLC) who underwent curative surgery from Jan. 1995 to Dec. 1998 at Severance Hospital, Seoul, Korea. The patients consisted of 90 men and 22 women. Nineteen patients were under 50 years old (17%), and 92 patients (82%) were smokers. Fifty-three patients had adenocarcinomas, while 59 patients had non-adenocarcinomas. Early stage (I and II) cancer was found in 64 patients (57.1%) and advanced stage (III and IV) found in 48 (42.9%). The prevalence of HPV 16, 18, and 33 were 12 (10.7%), 11 (9.8%), and 37 (33.0%), respectively. Smoking status, sex, and histologic type were not statistically different in the presence of HPV DNA. The presence of HPV 16 was more common in younger patients and HPV 18 was more common in advanced stage patients. This study showed that the prevalence rate of HPV 16 and 18 infections in NSCLC tissue was low, suggesting HPV 16 and 18 infections played a limited role in lung carcinogenesis of Koreans. However, the higher prevalence of HPV 33 infections in Korean lung cancer patients compared to other Asian and Western countries may be important and warrants further investigation.
