This study examined poor custodial grandparents' life story and care-giving experiences of their grandchildren. 8 grandparents were selected and in-depth interview and participant observation method were used. They showed a miserable life from the birth and discriminative experience of the deprivation of educational opportunities as childhood nadir experiences. They showed the regret for their inability as youth/midlife low point and financial difficulty as old life nadir experiences. In terms of care-giving experiences of their grandchildren, they showed non-voluntary care-giving, anxiety for the generational continuation of hardship, and lack of familial assistance. Poor custodial grandparents also used family-centered value, community-based social assistance, and self-assurance through their sacrifice as their adjustment strategy. Several research themes such as the importance of basic trust in childhood, the experience of financial difficulties, the importance of community-based social assistance, and self-assurance through their sacrifice were suggested for further research.

The purpose of this study was to explore the experience of relational aggression that old users of institutions for seniors have, understanding what that experience means. In detail, the study tried to determine the nature of the experience through a structural description of what and how the elderly users experience relational aggression. For the purpose, this study made profound interviews with 7 elderly persons who sustained such aggression while using the seniors' institution in Busan. In the interview, a non-structured questionnaire survey was conducted. Data were analyzed using Colaizzi's phenomenological approach. As a result, the study identified 32 meanings of relational the experience which were in turn divided into 16 subjects, and 5 categories like 'I who am powerless', 'I who am in an unmanned island', 'whirlwinds in my mind', 'I who send myself into the world' and 'I who am dwindling'. Based on this result, this research made practical suggestions for preventing relational aggression as mentioned above.

The purpose of this study is multi-faceted. Firstly, it is to examine the perceived differences in novelty experience, psychic distance, and satisfaction among Japanese, Chinese, and American tourists visiting Korea. Secondly, it is to investigate the effects of novelty experience on their overall satisfaction in Korea. Lastly, this study attempts to examine the role of psychic distance on the level of perceived novelty experience in Korea. A survey was conducted to 307 international tourists departing Korea at the In-Cheon International Airport. The results show that there is a significant difference in the perceived psychic distance, novelty experience, and overall satisfaction in Korea among Japanese, Chinese, and American tourists. Also, there is a significant effect of novelty experience on tourist overall satisfaction. The results further reveal that the degree of psychic distance is a significant determinant of the perceived novelty experience, which supports the effectiveness of psychic distance concept in predicting the novelty experience. The results of this study make a significant contribution to advancing our understanding of tourist behavior through the re-constructed concept of novelty.

At the stage of conceptual design of a helicopter, it is a general way using low fidelity analysis methods because of a large number of design calculations and trade-off studies. Determination of empirical parameters used in analysis codes for more practical design, depends on an user's design experiences, which effects on the accuracy and the fidelity of conceptual design results. Thus, more precise and logical method should be required to determine the empirical parameters used in the conceptual design of a helicopter. The present method is to be used not only in verifying the empirical parameters generated by design requirements, but also regenerate them if they contain any errors. Empirical parameters produced by present method were used to design a helicopter with a payload objective and performance constraints of an operating helicopter. As a result, weights and geometries of designed helicopter matched the target value within 5% significance level, proving that the suggested parameter generating method can be useful in the conceptual design of a helicopter.

The purpose of this study was to explore visitors' experiences based on two different types of ecological sites: natural and artificial ecological sites. Specifically, this study aimed to analyze the differences in the perceived experiences and satisfaction according to the perception of the visitors to the ecological sites. First, the analysis of measurement factors of visitor experience perception identified four factors such as ecological experience, environment friendliness, sociality, and relaxation. The comparison of perception according to the factor of visitor experience showed that there were significant differences between natural and artificial ecological sites and that the perceived visitor experience was generally higher in the natural ecological sites. The result of the analysis of the influence of the perceived visitor experience to ecological sites on visitor experience showed the relaxation had the largest influence for both natural and artificial ecological sites. The ecological experience and environmental friendliness also had a significant impact on visitor satisfaction in the natural ecological sites and artificial ecological sites, respectively. This paper also discussed the implications for planning and management issues at ecological sites.

The multivariate empirical distribution function could be defined when its distribution function can be estimated. It is known that bivariate empirical distribution functions could be visualized by using Step plot and Quantile plot. In this paper, the multivariate empirical distribution plot is proposed to represent the multivariate empirical distribution function on the unit square. Based on many kinds of empirical distribution plots corresponding to various multivariate normal distributions and other specific distributions, it is found that the empirical distribution plot also depends sensitively on its distribution function and correlation coefficients. Hence, we could suggest five goodness-of-fit test statistics. These critical values are obtained by Monte Carlo simulation. We explore that these critical values are not much different from those in text books. Therefore, we may conclude that the proposed test statistics in this work would be used with known critical values with ease.

Using the fourth data of the Korea Labor and Income Panel Study (KLIPS), this paper analyzed sexual differences in the promotion possibility and the promotion experience. Effects on wage of the promotion possibility and the promotion experience have been also discussed in detail. The promotion probability of a male worker in his current job is as high as twice than that of a female worker after controlling other independent variables. However, if we restrict the analysis to workers who either can be or was promoted, the sexual difference in the promotion possibility is greatly narrowed. This result suggests that the continuous career development without disruption is critical for the promotion of female workers. Analysing the sexual difference in wage using Oaxaca and Ransom's methodology, explanatory variables, such as human capital, residential area, etc., explained 69.5% of wage difference between male and female workers. Especially, 13.9% of wage difference was contributed to sexual differences in the promotion possibility and the promotion experience. This kind of empirical result emphasized once again the importance of promotion on wage.
