This study estimates the consumption needs of preretired households through target replacement ratio approach. Based on the Life Cycle Model, this study used the household expenditure function to derive the target replacement ratio appropriate for each household. The target replacement ratio is estimated using the 1996 National Survey of family Income and Expenditure by National Statistical Office. The estimated target replacement ratio was 82.4% for married couple households, and 85.1% for single households. Total retirement consumption needs during entire retirement period was 161,620,000 won for married couple households, and 50,532,039 won for single households.

Life Cycle Cost(LCC) is adopted to decide the target of safety level in designing suspension bridges. The LCC are evaluated considering two types of uncertainty; aleatory and epistemic. The nine alternative designs of suspension bridge are simulated to decide the safety level which can minimize the LCC. The LCC is calculated through the probability of failure and safety index including the uncertainty. This method results in the useful tool deciding the optimum safety level with minimal LCC as the main design factor.

우리나라의 산업별 교섭은 그동안 과거 기업별 교섭의 유산인 기업별 격차 때문에 많은 어려움을 겪어 왔다. 이 글은 이 문제를 해결하기 위한 유효한 수단으로 산업별 임금체계를 금속노조의 사례를 중심으로 설계하여 제안하고자 한다. 이 글의 논의는 세 부분으로 이루어져 있다. 첫째는 이론적인 부분으로 산업별 임금체계가 중층적인 산업별 교섭구조에 대응하여 연대와 차이의 원리를 반영하면서 동시에 세 가지 계급적 이해범주도 함께 반영해야 한다고 정리하고 이들 요구를 수용하기 위해서 생계비(생애), 직무, 능률, 숙련의 요소들이 임금체계의 항목으로 구성될 필요가 있다고 제시하였다. 둘째는 산업별 임금체계의 설계 시안을 제시하였는데 여기에는 최근의 국내외 임금체계 논의 동향과 관련된 현실적 함의가 함께 고려되었다. 즉 연공급의 문제점을 극복하고 유연적 경영환경에 대응하여 유연적 능률적 요소를 수용할 수 있도록 임금체계를 설계하였다. 셋째는 현재의 임금구조로부터 이 글에서 설계된 산업별 임금체계로 어떻게 이행할 것인지에 대한 전술적인 고민을 금속노조의 사례를 중심으로 논의하였다. 그리하여 현재 금속노조의 실태로부터 먼저 임금체계 자체의 논의가 초기업적 교섭의제로 제기될 수 있는 조건이라는 점과 그런 논의의 출발점이 기본급을 중심으로 이루어지는 것이 바람직하며 일차적인 전술적 목표가 연대의 원리가 적용되는 임금항목들에 있다는 점을 정리하였다.

To prepare for the explosive increase in maintenance costs of bridges according to the aging of infrastructure, future maintenance costs of bridges should be predicted. For this purpose, the management status of bridges was investigated and modeled as the upper limit of the performance level and the target management level according to the life cycle. This paper proposes methodologies and procedures for estimating the bridge maintenance costs using two models and existing cost and performance prediction models that consist of unit repair cost model according to the safety score, performance degradation model of bridges, unit reconstruction cost, and average reconstruction time. To verify the applicability, future maintenance costs can be forecasted for specific management agency considering the number of bridges, degree of aging, and current management status. As a result, it is possible to obtain the maintenance cost and safety level of an individual bridge level for each year. In addition, by summing them up to the agency level, the average safety score, ratio of the safety level, inspection costs, repair costs, and reconstruction costs can be obtained. In a further study, the changes in maintenance costs can be analyzed according to the changes in the target management levels using the developed method. The optimal management level can be suggested by reviewing the results.

The purpose of this study is to understand the meaning and essence of aged life, which Korean elderly experience in real life and restructure them in the context of time and culture. In order to do so an in-depth interview was done with 15 elderlies over the age of 60 living in Hwaseong City, an urban-rural composite area in Gyeonggi Province where diverse elderlies could be found. In result, first, Korean elderly's understanding of aged life had physical, familial, economical, leisure, and social restoration aspects. Second, it was found that the degree of understanding about preparation for aging and preparedness is quite low. Third, as the gap between actual preparation for aging and aged life that elderly dreamed of became wider 'resentment on children', 'denial of reality', 'physical and economical change', and 'experience from prolongation of life-cycle' was found. Based on such results following suggestions could be made. First, the awareness of aged life and preparation for aging should be strengthened and there is a need for diverse educations aiming successful aged life. Second, elderly welfare policy and practical intervention with an integrated perspective based on the realm of life-cycle are demanded. Third, there is a need to strengthen the Aged Income Maintenance System for existing elder generation. Fourth, an intervention about adaptation and coping means of life event is needed. Lastly, there is a need to expand and carry out the aged life planning program for future elder generation.

The present study assessed the $CO_2$ emissions of concrete according to the type and replacement ratio of supplementary cementitious materials (SCM) and concrete compressive strength using a comprehensive database including 2464 cement concrete specimens and 776 cement concrete mixes with different SCMs. The system studied in $CO_2$ assessment of concrete based on Korean lifecycle inventory was from cradle to pre-construction, which includes consistent materials, transportation and production phases. As the performance efficiency indicators, binder and $CO_2$ intensities were analyzed, and simple equations to evaluate the amount of $CO_2$ emission of concrete were then formulated as a function of concrete compressive strength and the replacement ratio of each SCM. Hence, the proposed equations are expected to be practical and useful as a guideline to determine the type and replacement ratio of SCM and unit content of binder in concrete mix design that can satisfy the target compressive strength and $CO_2$ reduction percentage relative to cement concrete.

The research team for the virtual construction development was established with the support of Korea Ministry of Construction and Transportation, and KICTEP (Korea Institute of Construction and Transportation Technology Evaluation and Planning). Its aims are to develop system that is to improve productivity & quality, to create a higher value-added business, and to cultivate international competitiveness in the construction industry. The virtual construction system is a design, engineering, and construction management information system that allows the project participants to effectively share the information throughout the construction life cycle with the support of 3D and design information. To achieve this, the research team focuses on developing several systems. First, the team focuses on developing for the pre-planning, the structural engineering, MEP, and the 3D based estimation system. Second, they focus on developing a simulation system for the construction process planning and feasibility study with help of the virtual reality technologies. Third, they focus on developing the CPLM (Construction Project Life-cycle Management) system for managing construction project data, and the decision support system that makes the collaboration among the project participants based on 3D technologies and information. We also focus on developing the SDAI (Standard Data Access Interface), the localized guideline for 3D design, and a training program. In addition, we focus on developing the undeveloped area of the commercial system and building an environment that can support the communication and collaboration in the construction life-cycle rather than developing the existing and commercialized system.
