The Korean Boletoxenus known as fungivorous are taxonomically reviewed as two species including a new recorded species, Boletoxenus incurvatus (Lewis, 1894). And the host fungus of B. incurvatus is revealed through this study. Therefore, we provide the taxonomical information as well as the ecological information on the host fungi of the Korean Boletoxenus species.

This research aims to suggest the direction of visual expression of a dokkaebi, based on the image of it that people possess. The method of the research is questionnaire survey. For the case study, fifteen picture books have been selected and thirty three imagery adjectives have been extracted. As the result this research poses the methods as following; firstly, cheerful and humorous appearance of Dokkaebi in Korean image, secondly, present of behavioral expression, for third, design with the visually specialized factor.

Rodgersia podophylla was a native medicinal plant cultivated in Korea. During the search for a new whitening natural herb, we found that underground part of Rodgersia podophylla showed inhibitory activity against melanin biosynthesis in melan-a cells by brocking tyrosinase activity. In addition, this plant exhibited protective effect on UV-B region. These results suggest that underground part of Rodgersia podophylla might be used as whitening agent for the skin.

Using GPS carrier phase whose cycle ambiguities are resolved, it is possible to perform precise survey requiring centimeter-level positioning accuracy. Because of an optical illusion, we cannot recognize the exact slope of Dokaebi Road. In this paper, we performed kinematic survey experiments in order to calculate the exact slope of Dokaebi Road with high positioning accuracy of CDGPS. By post-processing experimental data using CDGPS, it was possible to generate the exact vertical trajectory of Dokaebi Road with centimeter-level accuracy.

The study looks a shape of hybrid character in animation and suggests extended discussion to develop the Korean creative characters and to repeat traditional culture that can reproduce in mass media. First, this study considers Jangseung and Dokkaebi that appear frequently in the Korean traditional culture, and prepares a way to try to develop the Korean hybrid characters. To do this, I analyze examples of hybrid characters direction in as-found animation characters, and grasp the meaning of it. Hybrid character is classified as a character produced by mix and combination of shape and a character produced by shape exaggeration. And I shed new light on characters and meanings of Jangseung and Dokkaebi remaining as cultural assets. Through this, the study wants to help handling measure about a problem of character that the Korean animation has. Therefore, this study looks characters of description about imaginary creatures expressed in existing animations, and wants to shed new light on the Korean Jangseung and Dokkaebi regarded as from an object of folk religion and custom, to an object that is possible to use in the Korean traditional character development.

In the previous study, we reported the inhibitory effects of Rodgersia podophylla root extract on tyrosinase activity and melanin production in melan-a cells. However, mechanism of the inhibitory activity and in vivo assay were not yet examined. This study performed the examination of the effects of Rodgersia podophylla root extract on protein expression and in vivo depigmenting activity using melan-a cells and brown guinea pigs. As the results of western immunoblotting analysis, treatment of Rodgersia podophylla root extract reduced tyrosinase expression rates in 10 and 100 ppm concentrations, dose dependently. Moreover, Rodgersia podophylla root extract exhibited depigmenting activity on UV-B induced hyperpigmentation in brown guinea pig skin. These results suggested that Rodgersia podophylla root extract could act as whitening agent for the skin via not only direct tyrosinase activity inhibition but also reducing of tyrosinase expression.

In the delineation of geological structures using seismic exploration, it is very important to improve resolution of seismic data as well as accurate velocity model building and subsurface imaging. The resolution of seismic data can be enhanced by employing high-frequency energy sources or by applying deconvolution techniques in data processing. In marine seismic exploration, however, the main reason for degradation of resolution is the loss of specific frequency components due to ghosts. If we remove the ghosts, we can obtain broadband seismic data by avoiding frequency loss, and thus providing high-resolution subsurface images. Although ghosts can be properly filtered out in the data processing step, more effective broadband seismic technologies have been developing through the evolution of seismic instruments and the innovation of survey design. Overseas exploration companies developed brand-new configurations of receivers such as over/under streamer and variable-depth streamer, or ghost removal techniques using dual-sensor streamer to serve high-resolution imaging technologies. Unfortunately, neither broadband seismic instrument nor processing technique has been studied in Korea. In this paper, we introduce fundamental theories and current status of broadband seismic technologies to assist domestic researchers to study those technologies.
