This study was conducted to monitor residues of 10 veterinary drugs in food products. Various veterinary drugs were examined including enrofloxacin, ciprofloxacin, norfloxacin, oxolinic acid, amoxicillin, ampicillin, oxytetracycline, tetracycline, chlortetracycline, and doxycycline in beef, pork, egg, chicken, eel, flatfish, and rockfish obtained from 6 different regions (Seoul, Incheon, Daejeon, Gwangju, Daegu, Busan). Residues were detected in 21 (6.5%) samples out of 321 samples. In particular, 2 (1.0%) livestock samples had detected residues among 203 products, and 19 (16.1%) aquaculture samples had residues detected among 118 products. The most frequently detected drug residues in aquaculture products were oxytetracycline and amoxicillin, but the levels were mostly below the MRL (Maximum Residue Limit). In only one flatfish sample, amoxicillin was found at a level higher than the MRL (0.05 mg/kg). In livestock products, residues of most veterinary drugs were not detected. But enrofloxacin was detected in 2 chicken (Korean name: Ogolgae) samples at a higher level than the MRL (0.1 mg/kg as the sum of ciprofloxacin).

This study is conducted to find out problems in the implementation system of regional informatization policies in Korea and solutions to enhance the effectiveness in policy execution. The study uses research methodologies such as participant observation, interview and AHP for experts and employees of public organizations for regional informatization policies. Many implications were found in the analysis, including that policy relations, structure of the policy implementation system, and environment and contents of regional informatization policiesin Korea have to be innovated and re-organized. Especially, this paper emphasizes the horizontal and cooperative relationship between the central and local governments and redesigning of the legal system on the regional informatization. This paper also shows expectations on reshaping of the regional informatization policies with the paradigm shift of the government power toward decentralization. This paper also finds diverse views on the problems and solutions for the regional informatization policy implementation system based on different characteristics and interests of policy participants. This paper finds the possibility of applying the policy network model to regional informatization policy implementation, which can be supported by Rhodes & Marsh(1992)'s theory. Therefore, this paper shows the change of regional informatization policies can be expected through application of the policy network. Although the paper draws many academic and policy implications, they are limited to the implementation system of regional informatization policies only.

DNA-dependent protein kinase(DNA-PK) is involved in joining DNA double-strand breaks induced by ionizing radiation or V(D)J recombination and is activated by DNA ends and composed of a DNA binding subunit, Ku, and a catalytic subunit, DNA-PKcs. It has been suggested that DNA-PK might be $2^{nd}$ upstream kinase for protein kinase B(PKB). In this report, we showed that Ser473 phosphorylation in the hydrophobic-motif of PKB is blocked in DNA-PK knockout mouse embryonic fibroblast cells(MEFs) following insulin stimulation, while there is no effect on Ser473 phosphorylation in DNA-PK wild type MEF cells. The observation is further confirmed in human glioblastoma cells expressing a mutant form of DNA-PK(M059J) and a wild-type of DNA-PK(M059K), indicating that DNA-PK is indeed important for PKB activation. Furthermore, the treatment of cells with doxorubicin, DNA-damage inducing agent, leads to PKB phosphorylation on Ser473 in control MEF cells while there is no response in DNA-PK knockout MEF cells. Together, these results proposed that DNA-PK has a potential role in insulin signaling as well as DNA-repair signaling pathway.

This article focuses on reviewing place branding theories as a major toolkit of 'soft regional development'. Place branding provides sophisticate methodologies to strengthen city and regional image and identity. For effective place marketing practices, four of useful place branding tools are suggested. They include the methodology of place identity development, brand leadership system in local governance, construction of city brand architecture, and evaluation model for city brand equity. A process model is suggested for systematically organizing the diverse tools of place marketing and branding. The model is expected to be used as a framework of strategical soft regional development and planning. The place branding process model is to be an important theoretical and methodological basement of postmodern urban and regional development on which creativity, symbol and signs are more emphasized. More in-depth theoretical and empirical studies are needed. Geographical tradition and knowledge can play important roles in this inter-disciplinary process.

Korea's experiences in the use and development of nuclear energy are recognized as a successful model as a developing country in the international nuclear community. With these experiences, Korea is able to contribute to the progress of Korean nuclear industry and international society as a nuclear advanced country. This paper reviews and analyzes the current situation and major issues in securing the international legal status of RCA Regional Office hosted by Korean Government since 2002. In this connection, major political environments and relevant issues in facilitating the revision of RCA Agreement and securing legal status of the RCARO are also investigated. It is essential to amend the 1987 RCA Agreement or to conclude the its supplementary agreement for the securing of the international legal status of RCA Regional Office at the RCA policy meeting prior to extension of the agreement in 2017 and after. It is recommended for the Korean Government to establish and operate the inter-ministry governmental task force teams to facilitate and support the required actions in the national and diplomatic actions in the regional level for the sustainable development of the RCA and RCA Regional Office.

The occurrence of CRPS after a snake bite was very rare, only two cases were reported worldwide.

The purpose of this study was to investigate the effect of SAENGMAEKSAN extract on blood pressure and regional cerebral blood flow in rats. 1. High concentration of SAENGMAEKSAN extract decresed mean blood pressure in rats. 2. By depend on the dosage of SAENGMAEKSAN extract incresed mean regional cerebral blood flow in rats.
