  • This study aimed to investigate the changed consciousness and expenditure on Kyong-Jo after IMF economic crisis and the some factors which have effects on the change. The expenditure on Kyong-Jo included donations and gifts associated with congratulations and condolences. The data were collected through the personal questionnaire on Cheju Island. The sample consisted of 400 married adults whose age were between 20 to 65. The independent variables were some individual characteristics, household related variables, and Kyong-Jo related variables. The dependent variables included the change in consciousness and expenditure on Kyong-Jo. The data were analyzed by methods such as frequencies, means, Multiple Regression and Logistic Regression analysis. Major results were as follows. The respondents perceived that Kyong-Jo is fundamentally a good custom to help each other when some one is in the hard time. Their perception of the expenditure on Kyong-Jo has not been changed even since IMF economic crisis. 70% of the respondents staid that there was little difference of the expenditure on Kyong-Jo before and after IMF economic crisis. This trend is in contrast to the perception and the expenditure of the people who lived in the other residences after IMF economic crisis. The factors which had significant effects on the respondent's consciousness of the expenditure on Kyong-Jo were occupation, whether owns a house or not, household income, and household assets. The change of household expenditure on Kyong-Jo was effected by the respondent's sex, occupation, household income, household assets, and social network. These results suggested that the respondents on Cheju Island more strongly hold the conservative perception to the expenditure on Kyong-Jo rather than the people in other residences.

  • This paper presents the results of investigation on crystal, firing temperature and trace elements analysis of fragments 4~8 centriesexcavated from Kyong ju historical sites such as Wang kyong,Walsung, Hwangnam great tomb by application of optical microscope, neutron activation analysis and X-ray diffraction. Temper analysis of clay for identification of local or foreign production; Trace elements is not presented a unique chemical composition. That’s data have to be treated a statistical process in order to normalize. The results followed ;(1) Firing temperature could be estimated $700^{\circ}C$ on some softness pottery at Walsung and most of hardness others are $1,000^{\circ}C$ to $1,200^{\circ}C$.(2) Crystal structures are divided into three kinds of mineralogical composition(Quartz, Mullite, Feldspar).(3) Considering of the results of statistical data, chemical composition of Walsung is more similarly Wang kyong than Hwangnam great tomb.

  • Recently, as the technology of utilization for the ocean space is being advanced, floating structures are asked for being mare and mare huge-scale. A very large floating structure(VLFS) is considered as a flexible structure, because of a quite large length-to-breadth ratio and its geometrical flexibility. The main object of this study is to develop an accurate and convenient method on the hydroelastic response analysis of very large offshore structures on the real sea states. The numerical approach for the hydorelastic responses is based on the combination of the three dimensional source distribution methods, the dynamic response analysis method and the spectral analysis method. A model is considered as many rigid bodies connected elastic beam elements. The calculated results shaw good agreement with the experimental and calculated ones by Ohta.
