      • Unacceptable but Indispensable: Opium Law and Regulations in Guangdong, 1912-1936

        Xavier Paulès 고려대학교 민족문화연구원 2013 Cross-Currents Vol.- No.7

        During most of the period from 1912 to 1936, Guangdong Province was independent from the central government. The local authorities there were facing a dilemma regarding opium, as others were elsewhere in China. On the one hand, opium was considered the symbol of China’s weakness, and its suppression was a top priority; on the other hand, opium taxes represented an indispensable source of fiscal income. Some Guangdong power holders were truly committed to a suppression agenda, especially from 1913 to 1924. During this period, with the exception of a brief interlude from 1915 to 1916, opium laws were prohibition laws. Even if these laws were not always enforced with full vigor, the drug remained illegal in Guangdong. After 1924, opium was legalized, and the authorities openly ruled an opium monopoly. They came out with increasingly comprehensive regulations, which proved successful in increasing opium revenues. Yet, as this article makes clear, there was nothing like direct government control: traditional tax-farming arrangements with local opium merchants (though under stricter supervision) remained the backbone of the monopoly. The article also pays attention to the influence of the Six-Year Plan (1935–1940) launched by the Nanking government. As a credible set of suppression laws, it appealed to the Guangdong progressive elites who were hostile to opium. They urged the local autocrat Chen Jitang to take similar action. Chen made attempts to launch his own plans for suppressing opium, but they were unconvincing and nothing concrete came out of them. This article suggests that, in order to obtain a better understanding of how easily Chen Jitang was driven out of power in the summer of 1936, it is necessary to take into account the significant contribution of the Six-Year Plan in undermining his legitimacy.

        The need for sample preparation to modern instrumental analysis has been reviewed recently. The important reasons are sample clean up and sample concentration. Sample cleanup is required when impurities are present that interface with the analyte measurements in the analytical method of choice. In addition impurities which can damage expensive analytical equipment must be removed prior to sample introduction in to the instrument. Solid Phase Extration (SPE) which is one of the sample preparation has been developed since 1970s for replacing Liquid Liquid Extration (LLE). The advantage of this Method are summarized as follows 1.It was found that the increasement of sample concectration in the SOLID PHASE EXTRACTION exceeds over the normal use of solvent. 2.The time consuming work of passing sample through disc is much less shortened. 3.Much less solvent was used than Liquid Liquid Extration method. 4.Water sample containing more than 200㎎/L TSS was available in Disk Type Cartridge.

        The water quality criteria of the Yongdam basin is polluted over second grade. Trophic state in the area indicate supper eutrophic state. This study was conducted to analyze the distribution characteristics of the nutrient, and to find the interrelationships among them, focusing upon the eutrophication in the Yongdam dam basin. The results of this study were as follows; 1. Nutrients was estimated as total nitrogen of 1.021∼1,034㎎/ℓ. 2. The trophic state was supper entrophic, and the state of DO level was supersaturation in spite of high organic loads from the each tributary. 3. The limiting factor of the reservoir is T-P, according to the criteria of eutrophication. 4. After Dam construction, T-P concentration of 26㎎/㎥ and Korea Trophic State Index of 50 were predicted.

      • 타성상폐수의 주입이 하수처리효율에 미치는 영향

        정팔진,곽동희,송탁식 全北大學校 附設 都市및環境硏究所 1996 都市 및 環境硏究 Vol.11 No.1

        This study was to investigate the effects of dumping nightsoil, septage, and leachate to the activated sludge process receiving a mixture of sewage and industrial wastewater on its treatment performance. For the mixture of sewage and industrial wastewater, the overall removal efficiencies of BOD, COD and SS were 87.6%, 74.5% and 94.0% respectively. When the nightsoil and septage were dumped into the plant, the scum and foaming problems occurred at each stage of treatment unit. Direct dumping of the septage also induced the DO deficiencies in the aeration tanks, which resulted in a deflocculation problem in the secondary clarifiers. It may be favorite to pretreat it at the nightsoil treatment plant. When the leachate was dumped into the plant, the effluent qualities were highly fluctuating probably due to the presence of the toxic and inhibitory substances in it. It might be necessary to pretreat the raw leachate at the landfill site prior to dumping it into the plant.

        정팔진,조선영,류재웅 全北大學校 附設 都市및環境硏究所 1999 都市 및 環境硏究 Vol.14 No.1

        Livestock wastewater contains high organic and nutrient concentration, and its BOD, COD, SS are high. The treatment of two wastewater by biological method has some problems in the removal of nutrient and organic matter, so it needs for new treatment method. This study carried out concerned the treatment of live stock wastewater by plasma, with Lab scale and pilot scale test. Batch reactor was used in Lab scale test, total reaction time of high and low concentration wastewater was 32hr and 6hr respectively. Continuous reactor was used in pilot scale test, the system is consists of reactor, settling tank. The result of this experiment are summarized as following. · In the Lab scale test, Removal efficiency of COD, TN, TP, SS were around 70 ∼ 99%. · In pre-step, major removal effect is sedimentation and decomposition is major removal effect in post-step.

      • Aik Sang Busik System내의 종속영양세균의 분포 및 특성에 관한 연구

        정팔진,김성진,김민정 全北大學校 附設 都市및環境硏究所 1997 都市 및 環境硏究 Vol.12 No.1

        Aik Sang Busik System(ASBS) was developmented in Japan. In currently, this system is operating at many night soil treatment plants in our country. The purpose of this study is to exame the effects of heterotrophic bacteria on the aeration basin of this system to remove organic compounds. As a result of tests, isolated heterotrophic bacteria are about 115 genes. The predominant gene is Acaligenus spp which about 32 percent of isolated genes. Because the floc foming bacteria of isolated heterotrophic bacteria are about 54 percent, a major removal mechanism for organic compounds in this system depends on the floc foming bacteria. The total amount of hetrotrophic bacteria is 2.32×10 exp (7) c.f.u/㎖, which is a little lower than that in the activated sludge system. As liquid degradable heterotrophic bacteria are 1.57×10 exp (7) c.f.u/㎖, carbohydrate degradable heterotrophic bacteria are 1.22×10 exp (7) c.f.u/㎖10^7, protein degradable heterotrophic bactera are 1.48×10 exp (7) c.f.u/㎖, The distribution of liquid, protein, carbohydrate degradable heterotrophic bacteria are similar to that of the sludge system.

      • 活性슬러지 工程에 있어서 酸素利用率과 內呼吸率에 關한 硏究

        丁八鎭 全北大學校 1989 論文集 Vol.31 No.-

        It is very important to find the process variables that reflect the removal rate and capacity of organic matter by the activated sludge. Stenstrom and Andrews, they show that specific oxygen uptake rate(SPOUR) reflects immediately the presence of shock loads which the tradional food to microorganism (F/M) ratio does not. Thus oxygen uptake rate (OUR) can be an early warning indication abnomal conditions. This study has two purposes. First is to find the SPOUR and OUR when the synthetic substrate was added or not at the begining stage of reaction. Second is to study the feasibility on the Monod's and Dechamp's mathemetical models. The conclusions are as follows. (1) The results could be expressed to some extend by Monod's model. when S_o<<K_s, (2) There was no any trends in the application of Dechamp's and Kendrick's model. (3) In order to reduce the concentration of D O from 4mg/ℓ to 1mg/ℓ, it took longer as S_o/X_o ratio was larger and shorter as its ratio was smaller.
