經濟難國을 타계할 수 있는 중요한 方案은 國際競爭力의 강화이며 國際競爭力提高의 길은 生産性向上이다. 그것은 生産性이 企業利潤의 增大에 의한 財務構造의 改善과 實質所得의 增大, 原價節減에 의한 物價安定, 國際競爭力의 强化와 國家經濟問題의 核心的인 事項을 해결할 수 있는 지름길이 될 수 있기 때문이며 生産性에 대한 인식과 이를 向上하기 위한 對策이 절실하다. 生産性向上을 實現시키기 위하여는 企業의 全分野가 관심을 가지고硏究와 努力을 기하여야 한다. 生産性向上은 企業의 成長뿐 아니라 國家經濟的測面에서 內實있는 發展에 寄與하게 되므로 企業은 물론 政府次元에서도 支援制度를 推進하고 生産性向上運動이 國民意識속에 심어질 수 있도록 분위기 를助成하며 企業의 實質成長을 위한 政策支援을 彈化해야 한다. 生産性의 向上問題는 現代企業의 生産管理上의 가장 큰 當面課題中의 하나로부각되고 있다. 본 硏究를 통하여 우리나라 企業의 生産性向上方案을 위해 다음과 같이 提言한다. 1) 生産性에 대한 意識이 經營者뿐 아니라 온 國民의 마음에 심어줄 수 있는 運動展開가 필요하다. 2) 經營者는 技術開發과 黃新이 企業을 持續的으로 成長시킬 수 있으므로 技術黃新을 위한 冊究投資의 據大와 技術人力의 育成에 努力이 必要하다. 3) 設備投資計劃 의 合理化와 效率性을 向上시 킬 수 있는 設備管理의 效率化를 推進하여야 한다. 4) 動機願與를 提高시킬 수 있는 人事管理로 生産性向上에 努力하여야 한다. 5) 勞使間에 協力하는 意識의 바탕위에 相互協力과 參與를 통하여 勞使共同運命體的인 愛社의 勞使協助體制를 構葉하여야 한다. 6) 急變하는 企業環境에 能動的으로 對處하기 위한 經營意、識을 形成하여 生産性向上에 活用토록하여야 한다.

The amount of waste water generated in Korea is constantly an increasing trend in proportion to economic growth, and the conventional activated sludge process is widely being used for general waste water treatment. But the ministry of environment is rapidly strengthening the treatment standards of N and P (less than 20㎎/L of N, 2㎎/L of P from Jan. 1, 2008 in the whole nation) to prevent the eutrophication of lake water, and therefore highly advanced treatment technology is required not only in the existing treatment plants where the activated sludge process is being used, but also in newly constructed treatment plants for the treatment of N and P. This study is aimed at highly operating the engineering technology method was developed by domestic D company to eliminate N at the same time. Experiments were conducted in the G treatment plant located in Y city. The treatment process of the bioreactor was started from the principal equipment for the elimination of N, nitrification and the elimination of organic compounds. And it has an internal recycle piping from the end of the aerobic tank to the anoxic tank and external recycle piping from the final settling basin to the denitrification tank. By experiment of 4 types separate inflow of waste water to the denitrification tank and the anaerobic tank, and changes in staying time at the anoxic tank and the aerobic tank, the elimination of organic compounds in each type and the relationship in the efficiency between the elimination of N were researched.

The calcination characteristics of the waste Corbicula Japonica and Ostrea virginjca shell were examined for the future use as desulfurization sorbent. The weight variation was measured according to thermal-decomposition using TGA and observed variation of the phase. The qualitative and quantitative analysis of the sample were performed using XRD and the structural analysis, SEM. The results of TGA and XRD experiments showed that the almost all of the raw samples Corbicula Japonica and Ostrea virginjca were changed from calcite to lime by firing and calcination reaction. The result of SEM experiment showed that the plate type of the raw sample was changed to circle type, so the surface area ratio was increased. Above results suggested that waste Corbicula Japonica and Ostrea virginjca were usable in the viewpoint of the reuse of resource and the decrease of environmental pollution.
