The coast area of our country has various tourist attraction factors of its own such as plenty of islands, uncontaminated waters and so on. Nevertheless, sea tourism and leisure facilities have not been developed enough since the national tourist/leisure policies have mainly been focused on the land tourism so far. Recently, the lake and sea areas are becoming more an more popular to people for spending their leisure times, and they, especially the young generations, are eagerly searching for some good ocean spots to enjoy the dynamics maritime sports. In this paper, we worked on the first design phase of environmentally and visually adaptive yacht, taking the cost effectiveness and the safety factors into account as well.

The purpose of this study was to investigate the effect of generation on consciousness toward wedding ritual and to compare the difference in their consciousness between the young and the old. Data were obtained from 489 individuals living in Seoul. OLS regression analysis was used to identify the effect of generation on consciousness toward wedding ritual. The effect of generation was significant in the consciousness of wedding procedures, while it was not significant in the consciousness of wedding expenditures, holding other factors constant. [t was also found that procedure-important style was associated with more expenditures on wedding. The findings of this study suggested that the materialism had an important effect on the consciousness of wedding procedures for both generations. Understanding these factors is useful for family resource management professionals and educators who develop educational programs to build desirable wedding culture in Korea.

In this paper, the development history of random packings for several generations was briefly introduced. We demonstrate the application of 3D printing to the fabrication of Pall rings, directly using computer aided design (CAD) models. The CAD was used to design Pall rings with different number of blades. The models were then printed by using UV curing of acrylonitrile-butadiene-styrene (ABS) resins. The results show that 3D printing is a promising method for producing precisely controlled packing materials. It is also expected that 3D printing is helpful for the fundamental studies of highly efficient packing materials with complex geometrical shapes.

Recently, Korea suffered serious social conflicts between generations due to population aging. Anxiety about depletion of the National Pension Fund is one of the social problem to young generation, because of the uncertainty that they will not able to receive the pension they paid. At the same time, due to the high housing rent in Seoul metropolitan area, the demand for housing welfare and supply of public rental housing for young generation was increased. There are some opinions about using National Pension Fund to supplying public rental houses in the society. In this research, we were concentrated on finding the suitable areas for the public rental house using National Pension Fund. First, verifying the validity of the investment using National Pension Fund for the public rental housing was done. And spatial statistical methods were applied to explore the suitable areas for the public rental housing in Seoul metro area. Finally, this study divided young people into three groups and analyzed ways to supply public rental housing for each group in proper areas by their demand. This research's ultimate goals are mitigating the conflicts between the generations and achieving both profitability and publicness of National Pension Fund.

This study portraits the way of self-preparation for death among the elderly and examines the meaning and values attached to the elderly-care by their family and friends through the analysis of Kyung-ran Jo's novels. First, the author describes the difficulties and inner conflict of women who provide care for the elderly, especially those facing death in the near future. She also describes how the acceptance of death and self-discovery among the caregivers can be developed from the experience of long term care. These are consistent with the arguments by Ecofemnist on positive sides of providing caregiving in an aging society. In her novels, caregiving from young women is not described as the consequences of internalized gender norms of traditional Confucian culture. Rather, it is depicted as attitude toward a life in a commune where the meaning of life and death of elderly is shared between generations. In addition, struggles of the elderly figures against diseases and the process of their death provide an opportunity for young caregivers to overcome the trauma of other's death witnessed in their childhood. They lead the young caregivers to reflect themselves by raising ontologistic questions on life and death. The author shows the communication between generations presenting the self-preparation of death from the old generation undergoing irreversible aging and caregiving activities of significant others from the young generation. In doing so, the author points out the ethical grounds for diseases and death in old age given the condition of personalization of death in the modern society.

Locust gall midge (LGM), Obolodiplosis robiniae (Haldeman) (Diptera: Cecidomyiidae), is a cecidomyiid insect forming roll-up galls on leaves of Robinia pseudoacacia Linnaeus (Fabaceae). LGM, known as native to North America, was reported from Korea and Japan in 2002. LGM was observed weekly or biweekly to clarify their voltinism and distribution within the crown of the host tree in two sites of Osan and Siheung in Korea from May to August, 2007. Density of LGM was investigated based on the number of larvae per leaf. Two generations of LGM were observed in Siheung site whereas three generations in Osan site during the present study. The result indicated that LGM had at maximum three generations per year. The density of LGM in Osan was higher in the upper crown of the host trees than middle or lower part. In Siheung, LGMs were distributed more on the exterior of the lower crown than the interior. The average number of larvae per gall was $3.3{\pm}0.1$ and $2.8{\pm}0.1$ individuals per leaf in Osan and Siheung, respectively.

Korean commercial-organized girl groups were remarkable in the late 1990's. However, by the late 2000's, girl groups had an even more profound effect on Korean popular music compare to past influences. This study aimed to analyze the social-cultural meaning of the changing appearance of girl group between the first and second-generations. For this purpose, this study analyzed media image and text, based on a social-cultural context, about 13 girl groups. The results are as follows. First, while the first -generation girl group tended to maintain girlish/sexy images trying to the male desire, the second -generation girl group strategically showed various sexual identities such as femininity, masculinity, masculinity and androgyny along with contextual sexual images. The reason why girl groups increased the number of strategic images featuring various sexual identities was in order to appeal to a wide, diverse audience. Second, the second generation girl groups had - slim bodies with great athleticism, basically due to trainee system. Because of this, their semiotic body images have been commercially used to promote the consumption. Third, the second generation girl groups - were the bigger stars than first generation girl groups - because the members worked in many different fields. Therefore, the group members' images were successful consumed directly and then reproduced symbolically. Fourth, each member of the second -generation girl groups characterized by appearing in diverse, yet familiar images, through various media sources. Although the intention of this was to have recognition and popularity, it became difficult for them to change their image once one particular image was deemed popular.
