Objectives: This study aimed to analyze the factors influencing the life satisfaction of retirees(n=1,919) in one-person and multi-person households using the 2015 wave of the Korean Retirement and Income Study, collected by the National Pension Service. Methods: Frequency analysis and χ2-test were performed to examine the general characteristics and relation between one-person and multi-person household retirees. Logistic analysis was conducted to examine the factors affecting life satisfaction. Results: Public pension income was a statistically significant factor affecting life satisfaction, economic, health, and life in multi-person households. Conclusions: To improve life satisfaction after retirement, selective insurance benefits are needed depending on the type of household. Moreover a policy for expanding labor market participation is needed.

This study measured the causal relationships among tourist-perceived sacrifice, service quality, service value, and behavioral intention of employee's service. A total of 224 questionnaires were completed. The equation model was used to measure the causal effect. The results demonstrated that the structural analysis result for the data was an excellent model fit. The influences of perceived value and service quality on service value were statistically significant. As expected, service quality and service value had significant effects on behavioral intention. Moreover, overall service quality played a mediating role in the relationship between perceived sacrifice and service value. Service value played a mediating role in the relationship between service quality and behavioral intention.

탄산화는 콘크리트 내부로 이산화탄소가 확산되어 매립 철근에 부식을 유발함으로서 콘크리트 구조물의 구조적, 재료적 성능을 저하시키는 열화 현상이다. 결정론적인 방법을 통한 내구수명 평가는 일반적이지만, 하중 및 콜드 조인트 효과를 고려한 확률론적 내구수명 평가에 대한 연구는 매우 제한적이다. 본 연구에서는 확률 변수를 피복 두께, 이산화탄소 확산계수, 외부 이산화탄소 농도, 내부 수화물 반응량으로 정의하고 취약부와 하중 조건을 고려한 확률론적 내구수명 도출을 MCS (Monte Carlo Simulation) 기법을 통해서 진행하였다. 각 확률 변수의 평균을 1.0 ~ 3.0배로 변화시키고, 변동계수를 0.1 ~ 0.2까지 변화시키면서 내구수명을 평가하였다. 분석한 결과 피복 두께에서 47.7%의 내구수명 감소율을, 이산화탄소 확산계수에서 11.4%의 내구수명 감소율을 나타내었다. 파괴 하중에 30% 및 60%의 압축 및 인장 하중을 고려한 결과, 콜드 조인트가 고려된 경우 GGBFS 콘크리트가 OPC 콘크리트보다 탄산화에 대한 높은 저항성을 보였으며, 인장 영역에서는 사용 재료에 상관없이 선형적으로 내구수명 감소가 평가되었다. 또한 압축 하중 60% 조건에는 미세 균열의 진전으로 인해, 모든 조건에서 빠르게 내구수명이 감소하였다.

The purpose of this study is to identify the cognitive measurement scale of residential life management of apartment residents. The questionaires were distributed to 550 housewives and 392 questionaires were analyzed in this study. For the construct validity of this residential life management, the methods of factor analysis was used. As the results, 5 factors of residential life management of apartment residents were extracted. They are 1) Residential life covenience service, 2) Residential life support service, 3) Resident's activity support and announcement of managerial works. 4) Safety and order sustaining, 5) Precaution to accident.

After late 1980s, new approach is needed for satisfying with people's various information needs and better quality of life on Korean extension service. The United States began modern extension service at first and has influenced many countries. Cooperative extension service has helped people practically by searching into people's problem and developing various channel to diffuse. Cooperative extension adopts changes in extension service environment and puts them to use. Based on the extension service in the United States, following recommendations were suggested; 1) carrying out extension service to meet the changing needs of people, 2) strengthening the extension function of agricultural Colleges, 3) review of cooperative agricultural research and extension, 4) developing programs and management, 5) accumulation agricultural information and utilizing them.

RAM (Reliability, Availability and Maintenance) has been applied to design and analysis tools which affects system's operational sustainability and its life cycle cost as RAM-c(2009 DoD). RAM-c plays also an important role to guarantee the system engineering for mission assurance. Reliability is highly related to the probability of system failure. Availability means mission capability or the condition of ready to mission. Maintenance includes both the repair to recover the system in the event of failure/unexpected breakdown and proactive maintenance to prolong the design service life of the system or machinery. It is the purpose that this paper is to analyze and conclude the objective service life of UAV. The more UAV is operated, the less the level of its reliability becomes. Repairing failures and supplying spare parts on time, system reliability could be improved up until the time over target. Applying statistical Weibull distributions, this paper suggests the analysis of the design service life and economic life of UAV based on RAM-c with operational data.

PURPOSES : Performance evaluation of four types of asphalt concrete overlays for deteriorated national highways. METHODS : Pavement distress surveys for crack rate and rut depth have been conducted annually using an automated pavement survey vehicle since 2007. Linear and non-linear performance prediction models of the asphalt concrete overlays were developed for 43 sections. The service life of the asphalt overlays was defined as the number of years after which a crack rate of 30% or rut depth of 15mm is observed. RESULTS : The service life of the asphalt overlays was estimated as 17.4 years on an average. In 90.7% of the sections, the service life of the overlays was 15 years or more which is 1.5 times the life of conventional asphalt concrete overlays used in national highways. The performance of the overlays was dependent on the type of asphalt mixture, traffic volume levels, and environmental conditions. CONCLUSIONS : The usage of stone mastic asphalt (SMA) and polymer-modified asphalt (PMA) for the overlays provided good resistance to cracking and rutting development. It is recommended that appropriate asphalt concrete overlays must be applied depending on the type of existing pavement distress.

본 연구는 산재장애인의 재활서비스와 일상생활만족의 관계를 알아보고, 이러한 관계에서 의료재활서비스와 심리사회재활서비스, 직업재활서비스 만족도가 어떻게 영향을 주고 있는지 알아보고자 하였다. 이를 위해 근로복지공단의 산재보험패널조사 1차년도 자료를 활용하여 조사대상자 2,000명 중에서 산재장애가 있으면서 재활서비스를 이용하는 977명을 대상으로 분석하였다. 제시된 3가지 모델에 대한 변인간의 관계는 SPSS Macro 및 Sobel 방법을 적용하여 산재장애인의 의료재활서비스와 일상생활만족의 관계에서 직업재활 서비스의 매개효과 분석을 실시하였으며, 심리사회적재활서비스의 조절효과를 살펴보기 위하여 자료를 평균중심화하여 회귀분석을 하였다. 분석결과, 의료재활서비스에 대한 만족이 높아지면 직업재활서비스에 대한 만족이 증가하고, 직업재활서비스에 대한 만족이 높아지면 일상생활만족이 높아지고, 심리사회재활서비스가 높아질수록 산재장애인의 의료재활서비스가 일상생활만족에 간접효과의 영향이 있는 것으로 나타났다. 이를 바탕으로 산재장애인이 재활서비스를 통해 일상생활만족을 높이기 위한 실천적 함의를 제시하였다.
