  • This study was undertaken to evaluate the immune responses to sheep red blood cell (SRBC) and potential anti-tumor effect of Bacillus Calmette-Guerin (BCG) in the mice bearing rumor induced by DMBA. The frequencies of tumor appearances were 62% in DMBA-treated mice and 14% in DMBA and BCG-treated group, respectively. Cellular immune response such as delayed-type hypersensitivity (DTH) to SRBCs, natural killer (NK) cell activity and antigen-binding cell (ABC) assay were decreased apparently in the tumor bearing mice compared to the normal controls. Humoral immune responses such as hemagglutinin (HA) and hemolysin (HE) were noted to be reduced in the tumor bearing mice, but the spleen index increased in tumor bearing mice. All the immunological parameters in the DMBA and BCG-group appeared to be higher than those of only DMBA-treated group. These results indicated that DMBA-induced tumor suppressed host immune responses. Also, they imply the idea that BCG enhanced the immune responses of tumor-bearing host and antitumor effects.

  • While social networks have become very popular and powerful way of connecting people and sharing new information, they also effectively spread wrong or biased information to the public. We examine the so-called "Shandong peninsular rumor" that claims Chinese government is responsible for the increased air pollution in South Korea and Japan, by moving pollution-causing industries near Beijing to the Shandong peninsular which is close to South Korea. We demonstrate that the amounts of $NO_x$ and $SO_2$ emissions inferred by space-borne monitoring and regional air quality models show clear declining trends in past several years. We do not have any evidences to support the relation of Shandong peninsular emissions change to South Korean air quality.

  • The Kyeongbok Palace was completely renewed during the reign of King Sejong, the fourth King of the Joseon Dynasty(1392-1910). The repair was done for the two main purpose; one was to obtain the dignity of the main palace of the dynasty, the other was to make the palace suitable for the performing of the various ritual ceremonies. It was under the reign of King Sejong that every detail of the procedure of the royal ritual ceremony. The procedure of ritual ceremony changed the buildings of the palace. The quarter of Sajeong-jeon, King's office, was changed remarkably from the original form as the building became the beginning and ending point of King's moving during the ritual ceremonies. The site of the palace had ill reputation from the point of geomancy since its establishment. King Sejong ignored the rumor and kept the palace as usual. In his later year's, Sejong had tried to build a detached quarter and a Buddhist shrine in the palace. But he had to give up his plan because of the retainer's strong opposition. The original layout of the Kyeongbok Palace could be remained as the King renounced his controversial personal wish. King Sejong deserves a full credit for the establishment of the Kyeongbok Palace as the main palace of the Joseon Dynasty.

  • Comic book has a different story structure from western movies, i.e. New Character->reaction->food->master mediation->effect of food->disappearance ->conclusion. Comic book is full of media traits. The master is like a shaman, who console people with food of memory. Food also is a media, which carries message of memory instead of savor itself. Restaurant is a media, in which many events occur and rhetoric of rumor pervade. Foods of memory massage our feeling sense, like a media. In conclusion, comic book has a analogous role to that of Marshal Mcluhan's Media theory.

  • $p16^{INK4}$, which is a 16-kDa polypeptide protein, inhibits the catalytic activity of the CDK4-cyclinD complex to suppress rumor growth. Both unlabeled and isotope-labeled human tumor suppressor $p16^{INK4}$ protein were overexpressed and purified to characterize biochemical and structural properties. The purified p16 binds to monomeric GST-CDK4 and exists in a monomer conformation for several weeks at $4^{\circ}C$. The circular dichroism (CD) data indicates that p16 contains high percentage of ${\alpha}$-helix and that the helix percentage maximized at pH value of 7.0. One-and two-dimensional nuclear magnetic resonance (NMR) data suggest that purified p16 from our construct has a unique folded conformation under our experimental conditions and exhibits quite stable conformational characteristics.

  • Shareholders solely depend on annual reports to make investment, credit and other decisions. Investors expect that information should be reliable, relevant, comparable, consistent and thus easy to use for decision making. But whether the importance of annual reports to all shareholders is equally significant is a question of research. Thus, this research study tries to find out the importance of reading annual reports to the investors. A questionnaire survey is conducted on investors considering thirty one general shareholders and six brokers. This research based survey finds that most of the shareholders have no knowledge about accounting or finance and they have little knowledge about capital markets due to lack of training. This study also finds that general shareholders read an annual report at least moderately except value added statement, chairman's review, director's report and rumor. This study recommends human resource should be developed through adequate training, and annual reports should provide transparent and quality information which will ultimately increase the confidence of investors.

  • Spam has become one of the top threats of micro-blogging networks as the representations of rumor spreading, advertisement abusing and malware distribution. With the increasing popularity of micro-blogging, the problems will exacerbate. Prior detection tools are either designed for specific types of spams or not robust enough. Spammers may escape easily from being detected by adjusting their behaviors. In this paper, we present a novel model to quantitatively evaluate information diffusion in micro-blogging networks. Under this model, we found that spam posts differ wildly from the non-spam ones. First, the propagations of non-spam posts mostly result from their followers, but those of spam posts are mainly from strangers. Second, the non-spam posts relatively last longer than the spam posts. Besides, the non-spam posts always get their first reposts/comments much sooner than the spam posts. With the features defined in our model, we propose an RBF-based approach to detect spams. Different from the previous works, in which the features are extracted from individual profiles or contents, the diffusion features are not determined by any single user but the crowd. Thus, our method is more robust because any single user's behavior changes will not affect the effectiveness. Besides, although the spams vary in types and forms, they're propagated in the same way, so our method is effective for all types of spams. With the real data crawled from the leading micro-blogging services of China, we are able to evaluate the effectiveness of our model. The experiment results show that our model can achieve high accuracy both in precision and recall.
