This study aims to analyze the preference of jacket design, practical factors regarding jacket-wearing and purchasing behavior for korean baby- boom generation women. The results are as follows: 1. According to the outfit preference survey, the silhouette most preferred by female baby boomers is the "X-line Silhouette", "hip length", "slightly fitted and well fitted". The preferred jacket colors for different seasons were grey and beige for spring, white and light yellow for summer, khaki and brown for fall and black and dark grey for winter. 2. According to the survey on factors to consider when purchasing jackets, 52% indicated that they "almost never" or "occasionally" had their jackets repaired after purchasing them. When purchasing jackets, the highest expected effect of looking younger by wearing a jacket was "looking 4-5 years younger". 3. According to the survey on price demands, the average purchase price for jackets was 160,000~200,000 won (27.80%) followed by 210,000~350,000 won (25.64%) and a significant difference existed based on the purchasers' economic activities.

This study describes the 3D design and analysis of a composite insulation boom of an aerial work platform for electric work. Structural analysis of the composite insulation boom was performed using ANSYS and the total deformation, equivalent stress, and normal elasticity were investigated at 150 mm, 500 mm, 1,000 mm, and 1,500 mm using a mounted strain gauge. The results of the analysis and test were similar in a linearly increasing slope and the difference in the strain value was about 10%. This difference depends on the compressive force in the manufacturing process.

Purpose: The purpose of this study is to measure psychological well-being and to examine the associated factors in male baby boomers using Korean Working Conditions Survey Data 2011. Methods: This study was based on the 3rd Korean Working Conditions Survey Data 2011, which was conducted from June to November 2011 by the Occupational Safety and Health Research Institute. The total number of subjects was 3,340 male employees, who were born from 1955 to 1963 and responded to the question regarding occupational stress. Chi-square and multiple logistic regression were used for data analysis using the SAS ver 9.3 program. Results: Approximately 54.5% of the male babyboomer employees did not have psychological well-being. Factors associated with psychological well-being were weekend-shift and occupational stress including job insecurity, organizational system, and lack of reward. Night-shift and long working hours influenced psychological well-being, but the difference was not statistically significant. Conclusion: This study is a meaningful attempt to measure psychological well-being and perform an analysis of associated factors in male baby boomer employees using nationwide survey data. We suggest a complex institutional supplement in terms of national and employers to increase the psychological well-being of baby boomers.

Purpose: This research was conducted to identify long-term care service needs in the baby boom generation. Methods: Data were collected from September 3 to October 9, 2012 targeting 196 baby boomers residing in Seoul and Gyeonggi-do with the measurement of long-term care service needs having five domains. Collected data were analyzed using the SPSS 20.0 program. Results: Demand for long term care service in those who preferred nursing homes was highest as $4.40{\pm}0.69$ in the safe environment domain. In case of those preferring home care services, demand was highest as $4.37{\pm}0.56$ in the social interaction domain. People who preferred nursing homes had higher needs in personal health care and improvement of the service quality domains. Those who preferred home care services showed diverse needs according to their characteristics. Conclusion: The baby boom generation had high needs in all the domains of long-term care services and such needs were diverse according to their characteristics. However, long-term care services had limitations that they provided standardized and uniformed services only. Therefore, health care services and improved quality services should be provided in a way of meeting the users' needs, and tailored services should be provided in consideration of the users' characteristics.

This study analyzes the dynamic response of a floating crane with a cargo considering an elastic boom to evaluate(or for evaluation of) its flexibility effect on their dynamic response. Flexible multibody system dynamics is applied in order to establish a dynamic equation of motion of the multibody system, which consists of flexible and rigid bodies. In addition, a floating reference frame and nodal coordinates are used to model the boom as a flexible body. The study also simulates the coupled surge, pitch, and heave motions of the floating crane carrying the cargo with three degrees of freedom by numerically solving the equation. Finally, the simulation results of the elastic and rigid booms are comparatively analyzed and the effects of the flexible boom are discussed.

Optimum design of movable hydraulic crane's booms for weight reduction was performed in this study. Since the boom weight of the present used booms is very heavy, it is needed to make them lighter structure as possible as we can. Optimum design was performed for the booms by changing from the hexagonal cross section to triangular truss structure under the conditions, which are the allowable stress for the present cross section must be maintained, and the optimized weight must be minimized. CATIAV5 was used for stress analysis and design variables were established as the height and width of the triangular truss structure. As the results, it is found that the height of the truss structure is increased in proportion to the height of the booms and the maximum stress for optimal truss structure was obtained as 412MPa, which is lower than the allowable stress for the present hexagonal cross section. The optimized weight of the booms is reduced to about 19.88% comparing to the original weight.

In this paper, the dynamic response analysis of a floating crane with elastic booms and a cargo is performed. The objective is to consider the effects of the elastic boom in the lifting design stage. Governing equations of the motion for the system which consists of interconnected rigid and flexible bodies are derived based on the formulation of flexible multibody system dynamics. To model the boom as a flexible body, floating reference frame and nodal coordinates are used. Coupled surge, pitch, and heave motion of the floating crane with the cargo which has 3 degree of freedom is simulated by solving the equation numerically. Finally, the effects of the elastic boom for the lifting design that the floating crane is required to lift a heavy cargo are discussed by comparing the simulation result between with the elastic boom and with the rigid one.
