This study examines the effect of consumption level on the life satisfaction of baby-boom generation and further examines the mediating effect of subjective expectation(standard of living and government policy). This research uses the panel survey to explore ageing society in 2012 made by Korean Labor Institute, which studied 1,756(born in 1955~1961). SPSS 21.0 Package was applied to analyze the date and multi-regression analysis was conducted. As a result, first, the findings show that as the consumption level increases, the life satisfaction of the baby-boom generation goes up. Second, the findings reveal that subjective expectation partially mediates the influences of consumption level on the life satisfaction of baby-boom generation. This study further discusses the theoretical and political implication of the direction properties on baby-boomer based upon the results of the study.

Purpose: Some of the most representative approaches are to apply next generation technologies to save energy consumption, fully automated control system to appropriately maintain environmental conditions, and autonomous assistance system to reduce labor load and ensure operator's safety. Nevertheless, improvement of upcoming method for soil cultured greenhouse has not been sufficiently achieved. Geometrical complexity of ground in protected crop cultivation might be one of the most dominant factors in design of autonomous vehicle. While there is a practical solution fairly enough to promise an accurate travelling, such as autonomous sprayer guided by rail or induction coil, for various reasons including the limitation of producer's budget, the previously developed sprayer has not been widely distributed to market. Methods: In this study, we developed an autonomous sprayer considering travelling performance on geometrical complexity of ground in soil cultured greenhouse. To maintain a stable travelling and to acquire a real time feedback, common wire with 80 mm thick and body frame and sprayer boom. To evaluate performance of the prototype, tracking performance, climbing performance and spraying boom's uniform leveling performance were individually evaluated by corresponding experimental tests. Results: The autonomous guidance system was proved to be sufficiently suitable for accurate linear traveling with RMS as lower than approximately 10 cm from designated path. Also the prototype could climb $10^{\circ}$ of ground's slope angle with 40 kg of water weight. Uniform leveling of spraying boom was successfully performed within $0.5^{\circ}$ of sprayer boom's slope. Conclusions: Considering more complex pathways and coarse ground conditions, evaluations and improvements of the prototype should be performed for promising reliability to commercialization.

This study is about the happiness of married women from the baby boom generation. The study aims to understand the impact of the married life of such women on the happiness index and to improve the happiness of married women by improving married life. The data for this study were drawn from the National Women and Family Panel Survey (4th year data) carried out by the Korean Women's Development Institute. The subjects for the final analysis totaled 885 married women from the baby boom generation, born between 1955 and 1963. Of these, 550 were married women in a dual income family, and 335 were married women in a husband-income family. IBM SPSS Statistic 21.0 was used. The findings from this study are as follows: First, the women's happiness index was higher in cases where the women had a more positive view of their husbands, the more often they were involved in leisure activities, the better their conflict resolution whenever there was a clash of opinions, and the more satisfied they were with the division of household labor. Second, in the case of dual income families, the women's happiness index was higher where they had a positive view of their husbands, their conflicts were better resolved, and the more satisfied they were with the division of household labor. Third, in the case of married women in a husband-income family, their happiness index rose the more positively they perceived their husbands, the more often they were involved in leisure activities together, and the more satisfied they were with the division of household labor.

This paper deals with development of an oil boom computation program (OBC Program) for effective response to oil spill. Currently, programs for showing required minimum quantities of oil skimmers and temporary storage tanks have been developed. However, a program for oil boom has not developed, which causes difficulties in oil spill management. The OBC program was developed using LabVIEW 2010 for solving above problems. The OBC program has following strengths: 1. Both experts and non-experts can calculate required quantities of oil booms, 2. The program can save response time, 3. It can reduce damage to properties and marine environment in proportion to reduced response time.

This study analyzed the poverty rate by poverty dimension, correlation between multidimensional poverty, variables that affected the number of poverty dimension and the probability of the poor or not. The sample consisted of 6,361 elderly households (1,561 baby boom birth cohort, 1,793 post-liberation birth cohort, 3,007 Japanese colonial period birth cohort) taken from the $12^{th}$ Korean Welfare Panel Study. First, the highest poverty rate among the baby boom birth cohort was 62.8% of employment poverty. The highest rate among the post-liberation birth cohort and Japanese colonial period birth cohort, was 82.5%, 92.3% of health poverty, respectively. Second, the highest coefficient in the baby boom birth cohort was .354 for asset poverty and relation poverty. In the remaining two cohorts, the coefficient for asset poverty and relation poverty was the highest at .268, .284, respectively. Third, the average number of poverty dimensions was 2.318 of the baby boom birth cohort, 2.921 of the post-liberation birth cohort, 3.564 of the poverty in the Japanese colonial period birth cohort. Also, the poverty rate for each cohort was 20.179%, 28.779%, and 50.083%, respectively. Fourth, the significant variables in all cohorts were gender, education, marital status, residence, and equalized ordinary income for the multiple regression analysis on the number of poverty dimensions. Additionally, age of the post-liberation birth cohort was significant, age and family numbers of the Japanese colonial period birth cohort were significant. Significant variables in logistic analysis on the probability of poverty or not were the same as those of regression analysis.

Special equipment used for snow removal is only used in the winter and must be moved into storage during non-winter seasons. However, when moving heavy equipment using a forklift within a limited space, safety accidents may occur due to deformation and damage due to the worker's limited visibility and excessive loading of heavy objects. In this study, the scissors boom of the developed heavy load transporter was conducted in two cases: link structural analysis and position-based structural analysis. In detail, the link structural analysis covers four cases of stress and safety factor according to material and thickness to optimize the specifications of the material selected during development, and the structural analysis according to position covers two cases before and after the lift, when maximum stress concentration is achieved. Safety was evaluated through finite element analysis. As a result of the study, when manufacturing a scissors boom type heavy load transporter that can withstand a load of 10 tons, the link showed safety at SS400 4.5mm or higher, and reinforcement is needed in the upper and lower structures, so it is judged to be useful in applying materials according to the load.

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.

The purpose of this study was to identify the pattern and perception of food consumption, mass restaurant use, drinking style, and food purchasing factors by cohort groups i. e., World Cup(W) generation, baby boom, and silent generation. Data were collected from 412 respondents including three generations by questionnaire method in April through May 2002. Analysis of variance and chi-square results indicate that there were significant differences among three generation groups for the pattern and perception of food consumption, the use of mass restaurant, preferred drinking style, and influencing factors for food purchasing. W generation are more likely to be influenced by sensibility factor than baby boom and silent generation. Considering food preference pattern, baby boom as well as silent generation prefer green vegetables than meats, and they must have Kimche when having meals. Similarities and differences in perceptional pattern types are discussed, and future implications for food and nutrition specialists and food marketers are provided.
