Objectives: The purpose of this study was to research 'Daeri' drivers who work for drunken customers as a substitute driver. This was the first study in Korea to investigate assault and verbal abuse experienced while employed as a 'Daeri' driver. Methods: In this study, we conducted a survey to investigate people who work as 'Daeri' drivers. The survey was performed from September 1 to 7, 2014. The participants were 166 adult men and women who work as full-time 'Daeri' drivers. Results: Participants who experienced physical violence and assault from the customers to the point of disturbing safe driving in a year were 36.1% of total respondents. People who experienced verbal abuse to the point of disturbing safe driving in a year totaled 80.4% of respondents. In addition, there were also qualitative research results. Conclusions: Acts that impede safe driving are a danger to both passengers and drivers. By protecting the safety of 'Daeri' drivers, we will be able to protect the safety of citizens. Therefore, it is necessary to make an effort to protect 'Daeri' drivers from customer violence. Furthermore, it is also necessary to research policy to emplace a legal system that can protect 'Daeri' drivers.

The precise diagnosis of the acute toxoplasmosis in pregnant women and immunocompromsied patients has critical importance. Most of the commercially available assays use the whole Toxoplasma soluble extract as the antigen. However, the assays currently available for the detection of specific anti-Toxoplasma antibodies may vary in their abilities to detect serum immunoglobulins, due to the lack of a purified standardized antigen. The aim of this study was production and evaluation of the usefulness of the recombinant Toxoplasma gondii GRA7 antigen for the serodiagnosis of Toxoplasma gondii IgM and IgG by ELISA. A total of 70 T. gondii IgM positive sera, 74 T. gondii IgG positive sera, and 60 sera from subjects who were not infected with T. gondii were examined. These sera were shown different absorbance values in ELISA test. To control the specificity of the rGRA7 other parasitic diseases, for example, echinococcosis, malaria, leishmaniasis, fascioliasis, and strongyloidiasis were tested of which none showed positive results. Sensitivity and specificity of the generated recombinant IgG ELISA in comparison with commercial ELISA (com ELISA) were 89% and 90%, and the sensitivity and specificity of the generated recombinant IgM ELISA were 96% and 90%, respectively. The results obtained here show that this antigen is useful for diagnostic purposes.

This study investigated librarians' perception and preference of cultural programs in the field of cooperation between school and public libraries. The findings are as follows: 1) Librarians and teacher librarians at school and public libraries perceive the importance of cultural programs in library service. 2) Online space was mostly preferred as a means of PR activities by librarians and teacher librarians at school and public libraries. 3) The preferred methods to cooperate projects between school libraries and public libraries were to implement programs through public librarians' field visiting, and to participate linkage program customized to individual school libraries. 4) Preferred types of cooperation were to sign MOU and to make a cooperative system between school libraries and public libraries.

Acute and chronic toxicities of sediment elutriate and surface water samples collected at Lake Shihwa were evaluated using standard toxicity testing organisms including Vibrio fischeri, Daphnia magna and Moina macrocopa. Acute exposure resulted in toxic effects in all surface water or sediment elutriate samples, except for those collected from the reed swamp and Okgu stream. The rainy season influenced the toxicity of the water samples, presumably either by dilution of point discharge or through introduction of non-point source contaminants through runoff. In the sediment, elutriate and surface water samples, copper was detected above potentially lethal concentration, which may in part explain the observed toxicity. Considering acute toxicities of the surface water streams that direct to the Lake Shihwa, efforts should be warranted to control and reduce discharge of point and non-point sources along Lake Shihwa.
