UR 협상과정과 WTO의 영향에 대한 평가

최찬호 한국농업정책학회, 한국축산경영학회 2000 농업경영정책연구 Vol.27 No.2

The Uruguay Round (UR) on Agriculture was initiated by a small number of exporting countries like the United States, European Union, and Cairns group who were motivated to transfer their internal problems in agriculture to international markets. Although they highlighted the theme of global agricultural reform by comparative advantage and welfare of the all participant, the Round was an unfair game of economic politics in the name of multilateral negotiation that could solve their accumulative problems of over-production, stockpiling, export dumping and increasing subsidies. In fact, the negotiation was prepared in advance by the policy reforms of the leading countries in a way to fit with their own needs and budget capabilities. As the result, the monopolistic power of those exporting countries has strengthened in the international market on the one hand; while deepening the disparities between the rich and poor and food security dependency of many importing countries on the other hand. Unfairness of the Agreement lies in the fact that; export- restrictions and embargos of exporting countries were allowed; but no exemption for importing countries other than admitting tariffication and minimum market access (MMA) in the rule of market access. This paper, in analyzing the nature of unfairness of the Agreement and the impact, on the basis of Korean experiences in order to provide information to those who are concerned in the agricultural arena of globalization.

To evaluate the storage characteristics of pheasant meat products, contents of aerobic, anaerobic and food poisoning bacteria as well as VBN were measured during storage at various temperatures. 1. During the storage Escherichia coli and food poisoning bacteria including Salmonella, Shigella and Staphylococcus were not detected from any of the pheasant meat products. 2. Total plate counts of aerobic and anaerobic bacteria increased with storage temperature, showing more than 10^6 CFU/g of most pheasant meat products within 5~10 days of storage at 20℃ and 30℃. However, frank sausage, loin ham, pressed ham and salad showed less than 10^5 CFU/g in 20~30 days of storage at 20℃. 3. When stored at 10℃, smoked product, electric roasted product and pressed ham showed the bacterial counts of more than 10^4 CFU/g within 10 days of storage. Frank sausage, loin ham and salad, however, showed less than 10^3 CFU/g in 10 days of storage at 10℃. 4. VBN contents of smoked product, electric roasted product and frank sausage exceeded edible limit of 20 mg%, showing more than 40 mg% and 8 mg% within 5 days and 10 days, respectively, of storage at 10℃. In contrast, loin ham, pressed ham and salad had the VBN of less than 20 mg% in 10 days of storage at 10℃. In summary, while pheasant meat products in general appear to be prone to microbial growth, loin ham and salad are thought to have a longer storage period than others, showing about 10 days of preservation at 10℃. Products other than loin ham and salad are suggested to be stored frozen or refrigerated at below 10℃.

A Study on the Oxidation of Cobalt Film

崔燦有 東國大學校 1975 論文集 Vol.14 No.-

The kinetics of the oxidation of Cobalt films have been studied using quartz microbalance from 600℃ to 900℃ under various oxygen pressures. The oxidations followed the parabolic rate law in all caces and the parabolic rate constant varied apporximately from 1.64×10^-12 to 1.11×10^-11 (g/cm^2)^2 sec^-1 The activation energies calculated from the plots of log K_p vs. 1/T varied between 0.08 eV and 0.3 eV in the above conditions. The 1/n values obtained from the plots of log K_p vs log Po_2 (or log K_p=1/n log Po_2) are about 1/5 to 1/3.7. The mechanism for the oxidation of the Cobalt film is discussed in accordance with other mechanisms such as nonstoichiometric mechanism, diffusion mechanism, and conduction mechanism, etc.

An noise analysis from industrial plants was performed at 450 locations in Pusan and Kyungnam Area. The locations of measurement were divided by the land use of the affected area (e.g., industrial, semi-industrial, agricultural, and green belt area). Nois levels from 158 locations(35%) exceeded the environmental noise standards. The equivalant sound level(Leq) calibrated by background sound level was recorded as 59.89dB(A), 58.93dB(A), 58.59dB(A), and 54.41db(A) at Kimhae-Gun, Buk-Gu, Ganseo-Gu and Saha-Gu, respectively. High levels of noise is generated because the noise from industry is not controlled within its plants and annoyances from the noise that imparts to t he environment is not concerned. An environmental noise standards should be set forth to regulate not only existing industrial plants but additional construsction as well.

The purpose of this study is to analyze a problem of the application of 'Korean building code' occurred by discord a zoning line and a lot line, and to find a way out of this problem. The application of 'Korean building code' is based on the development capacity which is decided by urban planning, and it is grounded that 'the total development capacity' should not be over-estimated for the public profit. In a lot, that is including several zones, we suppose to estimate the 'floor area ratio'&'building coverate ratio', which determine the lot's development capacity, by respective zone's area ratio.
