Post-traumatic Back Pain Revealed as Tuberculous Spondylitis -A Case Report-

Tuberculous spondylitis is a very rare disease, but it can result in bone destruction, kyphotic deformity, spinal instability, and neurologic complications unless early diagnosis and proper management are done. Because the most common symptom of tuberculous spondylitis is back pain, it can often be misdiagnosed. Atypical tuberculous spondylitis can be presented as a metastatic cancer or a primary vertebral tumor. We must make a differential diagnosis through adequate biopsy. A 30-year-old man visited our clinic due to back and chest pain after a recent traffic accident. About 1 year ago, he had successfully recovered from tuberculous pleurisy after taking anti-tuberculosis medication. We performed epidural and intercostal blocks but the pain was not relieved. For the further evaluation, several imaging and laboratory tests were done. Finally, we confirmed tuberculous spondylitis diagnosis with the biopsy results

Determinants of the Intention to Protect Personal Information among Facebook Users

This study aimed to examine predictors of the intention to protect personal information on Facebook. We conducted an online survey of 679 Facebook users in the Republic of Korea. The findings of this study showed that usefulness and ease of use had significant effects on attitudes toward protection behavior. The results also revealed that risk factors (privacy risk severity and vulnerability) had significant effects on protective behaviors. Based on our findings, we discussed the information protection of privacy on Faceboo

Facebook Addiction among Koreans : A Look at Communication-related Variables

As Facebook usage is surging at global levels, concern is growing over the addictive use of Facebook. This study seeks to explore the factors contributing to Facebook addiction among Koreans, a group living in one of the most wired countries in the world. This study tests the assumption that a person becomes addicted to Facebook due to his or her desire to maintain social relationships. It thus examines such influences on the tendency of Facebook addiction as quality of social relationship, communication motive, and number of Facebook friends. The results show that those who use Facebook for communication and information are more likely to be addicted to Facebook. Another factor influencing one s inclination to Facebook addiction is quality of relationship, which impacts one s motivation to make use of Facebook. The results also show that communication motive influenced both the number of Facebook friends and information-gathering habits via Facebook. The study finds that two determining factors of Facebook addiction are usage pattern of Facebook and communication motive. What does not explain a person s tendency towards Facebook addiction is that person s desire to maintain social relationships

The Structure of the Internet Flows in Cyberspace

This paper describes the structure of international Internet traffic based on data obtained from the Organization for Economic Co-operation and Development for July, 1998. It also describes the relationship between the structure of the Internet and international telecommunications, as well as telephone rates, language, physical location, trade blocs, international migration, student flows, and science and structural asynchrony. The results indicate that the structure of the Internet is significantly related to the structure of the international telecommunications, trade, science and student flow networks, as well language and asynchrony. In combination, only telecommunications, trade, science and asynchrony were significant, accounting for 49. 7% of the variance in the structure of the Internet.Barnett George A., Chon Bum-Soo, Rosen Devan.

Clustering Local Tastes in Global Culture: The Reception Structure of Hollywood Films

This paper describes the shared structure of Hollywood film consumption based on data obtained from the Variety International Film Guide (1995, 1998, 2000). It focuses on the consumption of the top 10 films in over 30 countries, using a longitudinal study to explain the structure of cultural consumption, how it has transformed over time, and how it is related to cultural factors. The results indicate that the structure of film consumption is comprised of three cultural clusters: local film-based, strong and weak homogenization clusters. The results suggest that countries consume the Hollywood films in different ways and have different selection for foreign films. Also, the results suggest that the film consumption pattern was significantly related to cultural zone network.Global Culture, Hollywood Films, Cultural Zones

Fatigue-free samarium-modified bismuth titanate film capacitors having large spontaneous polarizations

Fatigue-free and highly c-axis oriented Bi3.15Sm0.85Ti3O12 (BSmT) thin films were grown on Pt/TiO2/SiO2/Si(100) substrates using the method of metalorganic sol decomposition. The BSmT film capacitor with a top Pt electrode showed significantly improved values of the remanent polarization (2P(r)) and the nonvolatile charge as compared to those of the Bi4-xLaxTi3O12 (x=0.75) film capacitor, recently known as the most promising candidate for nonvolatile memories. The 2P(r) value of the BSmT capacitor was 49 muC/cm(2) at an applied voltage of 10 V while the net nonvolatile switching charge was as high as 20 muC/cm(2) and remained essentially constant up to 4.5x10(10) read/write switching cycles at a frequency of 1 MHz. In addition to these, the capacitor demonstrated excellent charge-retention characteristics with its sensing margin of 17 muC/cm(2) and a strong resistance against the imprinting failure.
