The purpose of the current research is to reconstruct the process in which changes in elderly support take place from the perspective of the elderly in rural areas. Six elderly couples were interviewed three times with the use of Schütze's 'autobiographical-narrative interview'. The entire interviews consisted of 17 sessions. Interviewed data was analyzed, following the method of Schütze's 'autobiographical-narrative interview analysis'. Research findings were as follows: Elderly support as experienced by the current elderly couples is mainly 'family support', which turned out to be 'dual structural shift' in the process of modernization. That is, there has been an 'internal structural shift' from 'family support on intergenerational, mutual support dimension' to 'family support on intragenerational self-support dimension' on the one hand. An 'external structural shift' has been noticed that realizes the 'socialization of family support' on the other hand. Additionally, a 'discrepancy' was captured between support norm and support behavior as occurred in the process of 'dual structural shift'. Perception on the 'dual structural shift' has proven 'ambivalent'. On the basis of these results, a critical discussion of modernization theory ensued, along with some implications for practice.

본 논문에서는 한국사회 내 2014년 이후 2022년 현재까지 진행되고 있는 다양한 생애주기별 재난안전교육 체계를 분석하여 재난 발생 시 자신의 생명과 재산을 보호할 수 있는 재난안전교육 인프라 구축을 위한 제언을 통해 시민 대상별 최적화된 재난안전교육 체계화를 모색하고자한다. 2014년 4월16일에 발생한 세월호 침몰 사고는 2015년 '재난 및 안전관리 기본법' 시행규칙의 일부 개정 및 이에 근거한 '국민안전의 날'이 국민안전의 중요성을 되새기자는 의미로 제정된 계기가 되었을 뿐만 아니라, 재난안전교육에 관한 전반적인 변화의 필요성을 깨닫게 해준 가슴 아픈 사건이었다. 이에 서울시 소방재난본부 현장대응단에서 2014년 말부터 시민대상 초기대응을 위한 재난안전 교육체계를 기획하고 10만의 안전리더 양성을 추진했다. 동시에 다양한 형태의 시민대상의 재난안전교육이 시, 도별로 진행되었다. 특히 서울 시민의 1%인 10만 시민안전파수꾼 양성을 위해 진행되었던 시민안전파수꾼 정책 사업을 위한 재난안전 교육체계는 시민을 대상으로 황금시간 목표달성을 통한 초기대응으로 재난규모를 최소화 할 수 있도록 안전에 관한 소양교육의 기본을 구성해 교육했고, 이는 시민 대상 재난안전교육의 방향에 대해 시사하는 바가 크다. 정책사업 초기 대학생 이상의 성인을 교육 대상으로 선정하여 교육이 진행되었고, 그 후 2018년 이후 고등학교 이상으로 교육의 대상범위를 확대하여 진행했지만 안전리더로서 역할은 한국사회 전체 구성원들의 인식이 필요한 부분으로 어린 시절부터의 반복 교육을 통한 안전문화가 시스템으로 구축되어 자연스럽게 습득되어 질 수 있도록 해야 한다는 필요성을 절감하게 되었다. 이에 다양한 생애주기별 재난안전교육 체계를 분석하여 국민스스로 재난 발생 시 자신의 생명과 재산을 보호할 수 있는 재난안전교육 인프라 구축을 위해 시민대상 재난 안전교육을 '황금시간 목표달성'을 준거틀로 기존의 중앙, 서울시, 부산시, 경기도 및 산하 교육청에서 실시해온 재난안전교육 체계 관련 문헌의 비교분석을 통해 시민 대상별 생애주기별 최적화된 초기대응을 위한 재난안전교육 체계를 모색하여 재난안전교육의 방향을 제시해 보고자 한다.

The road user cost in indirect costs as well as direct costs such as the inspection/ diagnosis cost and the repair/reinforcement cost should be considered as one of the important items in the life-cycle cost-effective design and maintenance of the bridges. To estimate the road user cost, this paper formulates the road user cost as a sum of the user delay cost and the vehicle operating cost considering the detour effect. A numerical traffic simulation and a regression analysis are performed to develop a regression model due to a time delay. The proposed regression model is applied to the generation of the maintenance strategy based on the life-cycle cost and performance, and its effectiveness and applicability is investigated. The road user cost has a great influence on establishing the maintenance strategy, and the proposed regression model could be successfully utilized to estimate the road user cost of a bridge.

Melvil Dewey has been evaluated as a person of library movement, a man of thought, and a pioneer. However, the life-long achievements as a teacher has not been considered in the domain of library science. The foundations of Dewey's thought of public library can be divided into two categories: school education and home education. Based on these two types of education, Dewey established the major role of public libraries in supporting the life-long education of the public. Regardless of the great achievement of Dewey in education, few research has been conducted. The purpose of this research is to consider the role of libraries from the perspective of life-long education based on the thought of Dewey.

This study present an optimum deck and girder system design for minimizing the life-cycle cost (LCC) of orthotropic steel deck bridges. The problem of optimum LCC design of orthotropic steel deck bridges is formulated as that of minimization of the expected total LCC that consists of initial cost, maintenance cost, expected retrofit costs for strength, deflection, and fatigue. To demonstrate the effect of LCC optimum design of orthotropic steel deck bridges, the proposed optimum LCC design is compared with the conventional method for orthotropic steel deck bridges design. From the numerical investigations, it may be positively stated that the proposed optimum design procedure for orthotropic steel deck bridges based on the LCC will lead to more rational, economical and safer design.

This study was intend to develop the optimal design method of suspension bridge by the reliability analysis based on minimization of life cycle cost(LCC). The reliability analysis was performed considering aleatory uncertainties included in the result of numerical analysis. The optimal design was estimated based on life-cycle cost analysis depending on the result of reliability analysis. As the effect of epistemic uncertainty, the safety index (beta), failure probability (pf) and minimum life cycle cost were random variables. The high-level distributions were generated, from which the critical percentile values were obtained for a conservative bridge design through sensitivity assessment.

This study aims to propose a lifecycle cost model for electronic records & archival management. For this purpose, the study identified cost elements based on analysing public records & archival management activities and proposed cost factors for management by applying data gathered from records centers & archives. The study employed various methods: desk research, activity analysis, a cost information survey and interviews with experts in digital preservation, and records/archival management. The study made the first step to the cost studies in electronic records management in Korea. It is expected to update the CoMMPER model and redefine activities of electronic records management. Further case studies based on the model is required.

In the maintenance and retrofit planning of a bridge system, the optimal strategy for inspection and repair are suggested by minimizing the expected total life-cycle cost, which includes the initial cost, the costs of inspection, repair, and failure. Degradation of seismic performance is modeled by using a damage function. And failure probability is computed according to the degree of damage detection by random vibration theory and the event tree analysis. As an example to illustrate the proposed approach, a 10-span continuous bridge structure is used. The numerical results show that the optimum number of the inspection and the repair are increased, as the seismic intensity is increased and the soil condition of a site becomes more flexible.

The purpose of this study is to explore cohort changes in first-time homeownership in Korea. The study collected qualitative data from individual interviews to explore the housing trajectories of different birth cohorts. As a result, Individual interviews facilitated an exploration of the decision making process of first-time homeowner with in a cohort context. The cohorts born in the 1950s seek a sense of security through homeownership, and have strong Korean sentiments of ownership. They tried various means to buy a house, and real estate market boom at that time played a role in the driving force. The cohorts born in the 1960s have less insecurity of tenure than the previous cohorts, but they still feel the need for homeownership. Since the currency crisis in 1997 caused the fluctuation of housing price, the 1960s cohort experienced a dramatic decline and rebound of assets while the previous cohorts had experienced a steady rise in housing prices. Finally, the attitude towards housing in the group of 1970s cohorts has changed from ownershiporiented to use-oriented.

초기생애단계의 일본송사리를 실험어류로 사용하여 TCDD와 PCB 126의 생물농축정도를 비교 측정하였고, TCDD와 PCB 126의 체외 배설에 대한 동태학적 특성을 비교 분석하였다. 생물농축실험은 초기생애단계의 새끼치어 및 어린 물고기에 TCDD와 PCB 126을 여러 농도로 물에 용해시켜 96시간 동안 정체된 상태로 폭로시킨 후 생물농축계수(BCF)와 지방-표준화한 생물농축계수(BCF$_{L}$)를 측정하였다. TCDD와 PCB 126의 일본송사리 초기생애단계의 새끼치어 및 어린 물고기에서 측정된 96-h BCF값 및 96-h BCF$_{L}$값은 폭로된 농도와 상관없이 비슷하게 나타나 반면, 생체크기가 클수록 그 값은 작게 나타났다. 일본송사리 새끼치어, 어린 물고기, 성어의 생체 내 총 지방함량은 각각 5.7, 4.2, 4.6%로 측정되었다. 체외배설 동태실험은 어린 물고기에 TCDD와 PCB 126을 3가지 농도롤 물에 용해시켜 96시간 동안 정체된 상태로 폭로시킨 후, flow-through장치로 공급되는 맑은 물로 옮겨 42일간 사양하면서 0, 7, 14, 21, 28, 42일에 생체 내 TCDD와 PCB 126 잔류량을 측정하여 분석하였다. 배설은 1차 반응속도론적으로 이루어졌으며 한 구획모형보다 두 구획모형이 더 적합한 것으로 분석되었다. 두 구획모형을 사용한 분석에서 TCDD와 PCB 126의 체외배설 반감기(t$\frac{1}{2}$) 및 배설속도상수($\beta$)는 각각 27.2일과 32.3일 및 0.025/d와 0.021/d로 측정되었다.
