The purpose of this research is to analyze the subjective perception pattern of social participation by using Q-methodology. Sixty-seven Q-samples were extracted from the Q-population which was constructed, along with analyzing previous research by conducting in-depth interviews with 15. A total of 50 babyboomers, male and female 25 each, participated in Q-sorting, and the data of 50 subjects was finally analysed using QUANL program and found that three factor structures(6 types) were appropriate accounted for 34.06% of the total variance. These six types were different in social participation spontaneity, motivation, preferring activities and constraint factors; 'an ordinary commoner' type and 'the doyen' type (factor 1), 'a social activist' type and 'a kicked out salaried worker'(factor 2), 'still-youth' type and 'now-senior' type(factor 3). According to these results, the researcher discussed theoretically and suggested some significant social welfare implications.

Large aperture antennas with long focal lengths in space have important application for telecommunications, Earth observation and science missions. This paper aims to understand the dynamics of deployment of large mesh antennas and to provide a multibody model for determining the driving forces for the design of reflectors and booms. The modular deployable reflector and boom are designed based on the deployment unit cell. A multibody dynamic model is formulated with Kane's equation and simulated using the pseudo upper triangular decomposition (PUTD) method for solving the constrained problem. Based on the multibody dynamic model, the kinetics of the deployment, the motor driving forces, and the structural dynamic deformation are investigated.

활선차량의 붐 끝단에 탑재되어 있는 로봇의 기준좌표계는 활선차량의 접근 위치와 붐의 확장 길이 및 각도에 따라 달라지므로 작업대상물과 로봇 사이의 상대 위치를 찾아내어 설정된 작업 경로를 보정하여야만 한다. 본 논문에서는 작업대상물인 애자 영상으로부터 카메라를 보정하는 기법을 제시하여 활선작업 차량의 붐 끝단에 장착된 로봇의 위치 및 자세를 측정할 수 있도록 하였다. 이를 위하여 핀홀 카메라 모델을 적용하였으며 원기둥 형태의 애자 영상으로부터 카메라 내부 파라미터 및 외부 파라미터를 추출하였다. 제시된 기법은 시뮬레이션을 통하여 효용성을 입증하였다.

This study attempted to reveal the characteristics of the Y generation, to derive the services of the next generation digital library, and to compare differences between the demands of the baby boom generation and the Y generation to some extent. As a result, first, it is shown that the digital device the Y generation uses the most, was a cell phone or smartphone, followed by desktop PC, notebook PC, and digital camera. Although there were some differences, the Y generation's use ratio of digital devices was substantially similar to the baby boomers'. Second, there was a significant difference between the Y generation and baby boom generation in terms of using digital services. While the Y generation used internet portals the most, the baby boom generation used e-mail service the most. Third, we surveyed the services which the Y generation and baby boom generation require for the next generation digital libraries, by grouping as follows: the cloud service, infinite creative space (maker space), big data, augmented reality, Google Glass, context-aware technologies, semantic services, SNS service, digital textbook service, RFID and QRCode service, library space configuration, a state-of-the-art display technology, and other innovative services. While the most demanded service by the Y generation was big data service, the baby boom generation most demanded digital textbook service.

The purpose of this study is to analyse suicidal ideation and to identify the effect of health behavior and heath status on suicidal ideation of female baby boomers by using Korea Health Panel Data 2017. The Korea Health Panel Data 2017 were collected from February to June 2017 and included 1,319 people responded to the question whether suicidal ideation. The data were analyzed by chi-square, t-test and multiple logistic regression using SPSS WIN 25.0 program. The ratio of suicidal ideation was 3.1% in female baby boomers. Influencing factors to suicidal ideation in female baby boomers revealed that spouse, eating problem, activity restriction, and presence of depression had more suicidal ideation by 7.21 times(CI=1.15-6.36, p=.047), 4.44 times(CI=2.05-9.61, p<.001), 4.63 times(CI=1.63-13.16, p=.004), 12.12 times(CI=5.36-27.37, p<.001) respectively. Therefore, it is required to develop a suicide prevention program that considers the characteristics of female baby boomers and factors influencing suicidal ideation.

한국 베이비붐세대는 은퇴 후 주거선택에서 은퇴 전과는 다르게 쾌적성과 편의성을 중시하여 선택할 가능성이 높을 것으로 예상된다. 또 은퇴 후에 주거면적을 일괄적으로 축소하는 것이 아니라 현재 보유 주택규모에 따라 다른 형태를 보일 것으로 추정된다. 그리고 은퇴 후 62.4%가 주거이동을 계획하고 있고 지역간 이동은 주거이동가구의 52.3%에 달하여 은퇴 후 활발한 주거이동이 예상되며, 지역내 이동과 지역간 이동에 영향을 미치는 영향변수도 다른 것으로 나타났다.
