    • 소규모 마을하수시설 처리공법 비교분석 및 효율적인 관리방법에 관한 연구

      홍종 계명대학교 대학원 2010 국내석사

      RANK : 1823

      9개 마을의 하수 처리에서 9개월간 BOD, COD, SS, T-N. T-P 대장균을 원수와 처리공법 제거 효율을 평가하기 위해 측정하였다. 하수처리시설의 용량이나 마을의 평균하수량에 관한 연구와 강수와 온도에 의한 제거효율의 연구에 초점을 맞추었다. 일반적인 마을하수의 평가에서 BOD, COD, SS의 농도의 경우, 모든 마을에서 비점오염원의 요인이라 생각되는 오염농도변화를 부분들을 확인 할 수 있었다. 공법 별 성능 평가 시, BOD와 COD, SS, 대장균의 경우 전반전으로 모든 공법에서 높은 효율을 보였으나, T-N와 T-P 제거의 경우 공법별로 차이를 보였다. C·B·T 공법의 J마을과 BSTS-II공법의 B 마을의 경우, 모든 수질평가 항목에서 안정적이고 높은 제거효율을 보여주었으나, 다른 마을의 평균하수량과 비교하여 큰 차이를 보여 객관적인 비교는 어려운 점이 있다. 연구되어진 마을에서 투입되는 하수량에 비해 큰 처리용량을 가지고 있는 것으로 나타났다. 평균 기온과 공법 제거 효율의 평가에서 상관성이 나타나지 않았으나, 큰 폭의 기온 변화에서 T-N과 T-P의 낮은 제거율을 나타내었다. 강수량의 경우, 강수량에 의해 공법별 제거 효율에 큰 변화를 보이지는 못하였고, 이는 모든 공법들이 유량 부하에 대하여 유량조정을 할 수 있는 전처리 시설들을 갖추었기 때문이라 사료된다. 본 연구는 기온과 강수량에 공법별 평가와 객관적인 활성슬러지 공법별 성능 평가를 통해 그 상관성을 연구하였으며, 이는 향후 마을 하수처리 공법 선정 시, 고려해야 할 사항과 공법들의 장·단점을 파악하는 데 있어 참고가 될 만한 자료를 제공할 수 있을 거라 예상된다. Nine sewage treatment plants (STP) were investigated over a 9-month period in order to measure the BOD, COD, SS, T-N, T-P and microorganisms of untreated village wastewater and to evaluate the removal efficiencies of different treatment systems. This study was focused on relationship between the treatment facility and the average sewage quantity generated, and on the treatment efficiency as affected by rainfall and temperature. In case of BOD, COD and SS thought to be the non-point pollution sources in all villages sewage, all pollutant were changed. Comparing the removal efficiency of treatments, all villages treatments showed high removal of BOD, COD, SS and microorganism, but significant capability differences was displayed in T-N and T-P. C.B.T(J village) and BSTS-II(B village) revealed stable and high removal efficiency of T-N and T-P. However, it is unreasonable to compare for treatment ability because the quantities of water in J village and B village much lower than others. It was founded that all the treatment capacities and much larger than those required. Considering the temperature, any relationship was not founded between removal and monthly temperature variation, but the removal efficiencies were dropped along with significant change of temperature. Rainfall did not affect any removal efficiency because of that all plants have pretreatment for water quantity. Based on results obtained in this work, this research could be the reference to choose the appropriate sewage treatment technology in the future.

    • 성과평가 기반의 실행공동체 핵심 전략 도출 방법론 : A Methodology for Identifying the Critical Strategy of CoP based on Performance Evaluation

      RANK : 1823

      Although knowledge is the key to success, it is simply too valuable to be left in an organization. The CoP(Community of Practice) within an organization is a practical way to manage knowledge in an organization as systematically as other critical assets in order to deploy and share it. The availability of the right information at the right time based on performance evaluations has become critical. It is essential to improve the management and planning of firms service based on performance evaluations, because “what you measure is what you get”. However, research related with CoP, has focused on the value of CoP. Therefore, we developed not only a holistic and systematic methodology for understanding and assessing the current position of CoP but also a methodology for extracting the main CSFs (Critical Success Factor) of CoP based on performance evaluation. We developed strategies, CSF and PM (Performance measures) of CoP based on BSC (balanced scorecard) process. To provide beneficial information in terms of grasping the whole picture of CoP, a methodology for the elementary expression of performance measures and the global performance expression of strategies and CSF was developed by using a desirability function. The weighted relative importance of strategy and CSFs was extracted based on the cause and effect relationship of BSC by using ANP (Analytic Network Process). IPA (Importance-Performance Analysis) was used based on weighted relative importance and a global performance expression of CSFs. This research delivered a holistic, systematic, and comprehensive methodology for cultivating CoPs. Furthermore, this research can give guidelines for designing and cultivating CoPs. It can help leaders and organizers to build CoPs in organizations systematically. 실행공동체란 다양한 배경과 경험을 가진 사람들이 업무와 관련된 목적으로 지식을 공유 및 습득하고 재창조하기 위한 커뮤니케이션 조직으로서, 동일한 관심사의 문제에 대한 향상된 방안을 찾기 위해 정기적으로 활동하는 조직이다. 지식경영의 가치를 극대화하고, 구성원들의 자발적인 학습을 통한 학습조직의 실현을 위해 실행공동체는 이미 다양한 조직에서 이용되고 있다. 조직 내•외의 실행공동체를 구축•운영함으로써, 조직 역량의 강화, 자발적인 혁신, 일의 효율성 증대, 변화에 대한 민첩성의 증가와 같은 성과들이 가시적으로 나타나고 있다. 이러한 실행공동체의 성과와 관련된 연구는 활발히 이루어지고 있다. 그러나, 실행공동체의 현재 상태를 다면적으로 진단하고, 이를 토대로 핵심 전략을 도출하고자 하는 방법론에 관한 연구는 이루어지지 않고 있다. 국내의 유수 대기업뿐만 아니라, 중소기업에서도 실행공동체의 중요성 인식하고 있으며, 이미 실행공동체를 구축•운영하고 있다. 현 시점에서 성과지표를 토대로 실행공동체를 진단하고, 실행공동체를 전략적으로 이끌어 가는 것은 중요하다. 그러나 실행공동체를 다면적으로 측정하고 이를 토대로 핵심전략을 도출하여 실행공동체를 활성화하기 위한 연구는 이루어지지 않고 있다. 따라서, 본 연구에서는 핵심전략 도출을 위해 다음 단계로 구성된 방법론을 제시한다.

      The problem of administrative control is important to secure human right against power of public adminiration. Diversed and extended functions of administration has impacted on people's life, and most of Korean people has obeyed public administration's officer. Now, strenthened administrative power is the threat to people's life because of the abuse of administrative power. This is unde□ □sirable situation which must be improved in Korean administration. In this point of view, we want to introduct the Ombudsman, system, as Citizen's defender and Administration/s controller. The Ombudsman which was originated from the Swedish constitution in 1809 which was not only controlling the Administration branch but also securing human right, in other words, correction civillian grievances toward the government. Since 1950, the Ombudsman System has been adopted in many countries because At has proven an excellent means of democrative devices. The Ombudsman in an officer of the legislature, an investigator, Citizen's aider, Citizen's defender. He has Independency but he should present his annual report on his working to the National Assembly. In Korea, We find that the Ombudsman System As not adopted but there are several similar systems to Ombudsman an such as the Presidential office, the government united officer, the Inspect. But these organizations are not utlized effectively owing to functional problems and discrepancy in our political, social, cultural contingency. Owing to the grievances of people victimized by the administrative power, the government has been distrusted. The Ombudsman System has to be adopted in Korea in order to protect the people from the government's mistake and abuse of the Power. The desired Ombudsman System should be belonged to the legislature and his office hold be 4 years, and the Ombudsman System has from of committee. Furthermore the Ombudsman has staff to investigate and to aid his works. In such case we should expect that the Ombudsman do his work as a Critizen's defender in Korea.

    • The magnetic properties and microstructures of iron-based nitride systems for thin-film recording heads

      홍종 Stanford University 1999 해외박사

      RANK : 1823

      The control of process parameters and the development of new head materials have been critical steps to extend the performance of magnetic hard disk drives. As the recording density of disk drives increases, a medium with high coercivity and a head with high saturation magnetization and soft magnetic properties are required. In particular, Fe-based nitrides (FeXN, X=Metal) with a saturation magnetic flux density of over 20 kG have generated interest because of their potential as the write heads in high-density magnetic recording of over 40 Gb/in². Although extensive research has been undertaken on Fe-based nitride material systems and has demonstrated the promise of these material systems in high-density magnetic recording heads, numerous problems, such as low corrosion resistance and the degradation of magnetic behavior due to deposition geometry and conditions, still remain unsolved. Stable frequency response at high frequencies is also a major challenge for high-data-rate applications. Very few systematic studies on the magnetism of Fe-based nitrides have been performed, and the magnetism is not clearly understood as yet. The research presented in this dissertation demonstrates the high probability that Febased nitride systems such as FeRhN, FeTaN and FeTaN/AlN films can be incorporated into advanced write heads for a recording density of over 40 Gb/in²and a data rate of over 1 Gb/sec. The development of novel magnetically soft, high-saturation-moment Fe-based material systems such as FeRhN films and FeTaN/AlN laminates is discussed. To our knowledge, these material systems have not been studied before. Significant improvement in the soft magnetic properties of FeTaN films, especially when they are deposited on sloping surfaces, is described. This dissertation also clarifies the microstructural mechanism of the degraded magnetic properties of FeTaN films. The optimization of both magnetic properties and corrosion resistance has been a major concern for Fe-based nitride materials. It has also been difficult to achieve soft magnetic properties in Fe-based nitride films when they are deposited on the alumina-coated Al₂2O₃-TiC (AlTiC) composite substrates that dominate in the magnetic industry. We suc cessfully demonstrated that soft magnetic FeRhN films with a saturation magnetic flux density of ∼20 kG deposited by reactive RF sputtering can be made to have excellent pitting corrosion resistance and soft magnetic properties on A1TiC and Si substrates. In the electrochemical corrosion test, we found that, in air-saturated 0.5 M NaCl solution, which emulates an extreme case of the natural environment, the corrosion resistance of the FeRhN films is about the same as that of Ni80Fe20 films, irrespective of the nitrogen content. More importantly, the FeRhN films show higher pitting resistance than the Permalloy films in the solution. The soft magnetic properties of the FeRhN films on AlTiC substrates can be attributed to a decrease in the average grain size and an appropriate amount of the γ (FeRh)₄N phase. When the grains were small and consisted of α-(FeRhN) and γ(FeRh)₄N phases in the FeRhN films, a saturation magnetic flux density of ∼20 kG, an easy-axis coercivity of ∼1 Oe, an anisotropy field of less than 10 Oe, and a saturation mag netostriction of ∼5x10-6 resulted. The magnetic properties and microstructures of Fe-based nitride thin films on sloping surfaces, i.e., under an oblique angle of incidence during sputter deposition, have been poorly understood and difficult to control. A particularly serious problem was that the soft magnetism of Fe-based nitride films can be significantly degraded at the neck region of thin-film write heads, leading to poor head efficiency. We significantly improved the degraded magnetic properties of FeTaN films by reactive sputtering on sloping surfaces by applying high substrate bias power or lowering N₂/Ar flow rate ratio. The saturation magnetic flux density was ∼20 kG and the easy-axis coercivity was ∼4 Oe, irrespective of sloping angle, even at 60˚. We confirm that high substrate bias plays an important role in controlling the magnetic properties and microstructures of FeTaN films deposited on sloping surfaces. The increased mobility of adatoms caused by high substrate bias power promotes the (110) fiber texture along the surface normal and the uniform distribution of <100> axes in the film plane, which contributes to the soft magnetic properties of the films. We also found that the soft magnetism can be degraded due to a perpendicular anisotropy component, which arises from magnetoelastic and magnetocrystalline anisotropy. We confirm that it is important to control the crystallographic texture and magne toelastic anisotropy when incorporating soft magnetic, high-saturation-moment Fe-based nitrides into advanced thin-film write heads, particularly in their neck regions. In addition to soft magnetic properties, a flat response in the high-frequency range is required to achieve high-data-rate recording. FeTaN/AIN laminates show good frequency response at high frequencies and soft magnetic properties on both planar and sloping substrates. The coercivity of the easy axis is ∼1 Oe and the anisotropy field is less than 10 Oe. The frequency response remains flat up to 500 MHz, corresponding to a data rate of 1 Gb/ sec, for 0.1 ㎛-thick FeTaN films and 1 ㎛-thick FeTaN/AlN laminates with a saturation magnetic flux density of ∼21 kG.
