Water supply and sewerage systems are the large-scale urban infrastructure ejecting large amount of environmental load over the life-cycle. Therefore, it is important not only to optimize in the aspect of economical superiority and process efficiency but also to consider earth scale environmental impact. This study aimed to suggest the establishment of life cycle management(LCM) system as an integrated management solution in urban water supply and sewerage systems. As a result, the methodology for LCM system consisting of life cycle assessment(LCA), life cycle cost(LCC), life cycle $CO_{2}(LCCO_{2})$ and life cycle energy(LCE) was developed. Also, several case studies using the latest statistics data of water supply and sewerage systems were carried out to investigate the field applicability of LCM.

제약분야의 특허전략은 이해관계자의 입장에 따라 LCM 또는 에버그리닝으로 해석하고 있다. 오리지널 의약품 제약사는 특허전략을 기술 혁신의 노력인 LCM이라고 주장하는 반면 제네릭 의약품 제약사와 보건 당국은 오리지널 제약사의 특허전략은 값이 저렴한 제네릭 의약품의 접근성을 낮추어 항구적인 시장 지배의 목적인 에버그리닝이라고 주장하고 있다. 본 연구는 한국에서 거대시장을 형성하고 있는 오리지널 의약품의 특허출원과 특허분쟁사례를 통해 LCM과 에버그리닝을 어떻게 개념화하고 논의되어야 하는지 제시하였다. 본 사례 연구 결과 LCM은 신약개발의 새로운 기술 응용을 바탕으로 연구의 성과물을 특허전략과 연계하였다. 반면, 에버그리닝은 의약품 허가 장벽을 높이기 위한 방법중의 하나로 특허권을 활용된 것으로 판단된다. 본 연구결과를 바탕으로 이해에 따라 일방의 주장이 아닌 LCM과 에버그리닝의 개념화를 통해 차별화된 시각으로 논의를 이끌고자 한다.

Long Term Asset Management(LTAM) means a plan developed by using LCM(Life Cycle Management) process for optimum life cycle management of significant plant assets at each plant across the fleet. As a part of development of LTAM Strategies on nuclear turbines, a method so as to determine the future failure rates for low pressure turbine facilities at a nuclear plant was studied and developed by using both plant specific and industry-wide performance data. INPO's EPIX data were analyzed and some failure rate evaluation values considering preventive maintenance practices were calculated by using EPRI's PM Basis software. As the result, failure rate functions applicable to a priori and a posteriori replacement of low pressure turbines at a nuclear plant were developed and utilized in an assessment of economics of LCM alternatives on the nuclear turbine facilities in the respects of 40-year and 60-year operation bases.

In this study, carbon emissions and energy consumption were evaluated to establish a design strategy which has low energy consumption and carbon emission production, by using life cycle energy (LCE) and life cycle $CO_2(LCCO_2)$ calculation methods in life cycle management(LCM) tools. After improvement design projects, the energy consumption and $CO_2$ emission were calculated and compared in three sewage treatment plants (STPs), which are A STP, B STP, and C STP. The reduction of carbon emissions was 28,020.1 ton $CO_{2-}e/yr$, 37,399.6 ton $CO_{2-}e/yr$ and 8,788.3 ton $CO_{2-}e/yr$, respectively. Production of energy was 792 TOE/yr, 1,235 TOE/yr and 1,023 TOE/yr, respectively. As a result, the estimation of energy and energy self-sufficiency was 5.1 %, 14.5 % and 23.5 %, respectively. The result of this study shows the LCM can be contributed to establish strategy for energy and carbon emission reduction in sewage treatment plants.

The characteristics of Telecommunication Industry encompass not only hardware and software but also the service aspect of them. One way to improve the industry up to the international level in terms of hardware and software as well as service aspect is to comply with tile TL 9000 standard, which was established by QUEST Forum, the group consisted of U.S. communication industry, based on the ISO 9000 Quality Management System. In this study, design, establishment, implementation, maintenance and improvement of quality system for domestic telecommunication industry are thoroughly investigated based on TL 9000 standard, with its LCM(Life Cycle Model) model and measurements. Also, Process Approach is suggested to help the industry realize the system to meet its specific needs. In addition, specific examples with the successful certification to TL 9000 standard are presented.
