With the developments in the areas of IT and internet, the portal sites have provided a variety of services. The explosive growth of portal sites based on IR services has a great influence on information services and types of information provided typically by libraries. Because of various and useful information services, information users consider portal sites as a more useful information resource. With the user's changes in information resource the portal sites can be a threatening competitor to libraries as a information resource. To deal successfully environmental changes around libraries. IR agency service can be best solution. IR agency service is a sort of more advanced and expanded information services for information users who can not connect to internet or has no skill on IT area. In this paper, information users' opinion on their internet using behavior and IR agency service was collected and analyzed. Based on the result of survey. this paper proposes how to provide IR agency service and its expecting effect for libraries, especially public libraries.

This research was performed in order to investigate the origin, standard compound, and structural and physical properties of honeybee venom which used as natural antibiotic ingredients to animal. We compared the nucleotide sequence of mitochondrial cytochrome c oxidase subunit 1 gene (COI) of honeybees were collected from Gangwon, Gyeonggi, Chungnam, Gyeongbuk, Gyeongnam province and Suwon. As major constituent of honeybee venom, melittin was assayed by liquid chromatography. X-ray, differential scanning calorimetry (DSC) and fourier transform infrared spectroscopy (FT-IR) were utilized to examine the structural and physical properties of honeybee venom. Based on the 627bp sequence of COI, Apis mellifera ligustica was determinated honeybees collected from all six regions. Melittin content varied from 50.7 to 68.6 and averaged 59.8%. According to XRD analysis, honeybee venom showed regular crystal structure peaks at $2{\Theta}=8.5^{\circ}$ and $21.5^{\circ}$. DSC showed that the maximum degration temperature of powder was around $230^{\circ}C$. Through FT-IR analysis, we could identify cross-linking by the presence of peptide peak at 1,500~1,600 $cm^{-1}$. In conclusion, the origin of honeybee venom was Apis mellifera ligustica and effective ingredient standards was melittin content varied from 50.7 to 68.6 as natural antibiotic ingredients.
