  • Aging effect of sands showed insignificant result in comparison with that of clay, so that it has not been studied so far. But, as penetration resistance increase has been observed with the lapse of time after deposition and disturbance, aging effect of sands has been actively investigated by field tests, and recently many researchers are performing not oかy field tests but also laboratory tests on sands, so aging effects of sands have been also examined by laboratory tests. In this study, to observe the aging effect of undrained static shear behavior for Nak-Dong River sand, undrained static triaxial tests were performed with changing relative density$(D_r)$, consolidation stress ratio$(K_c)$, and consolidation time. These tests showed that modulus within elastic section increased as consolidation time increased, and in addition, phase transformation point strength$(S_{PT})$ and critical stress ratio point strength $(S_{CSR})$ also increased. But pore water pressure ratio$(u/{p_c}')$ decreased as consolidation time increased, so with this various result, aging effect of static shear for sands can be observed as well.

  • It was known that the aging effect of sands is insignificant in comparison with clays, and hence the study on this effect had seldom been performed prior to the early 1980s. However, field tests for this effect have been actively carried out since it was investigated that penetration resistance of reformed sands increased with the lapse of time. Recently, the aging effect of sands has also been examined in laboratory testings. In this study, undrained static triaxial tests were performed to evaluate the effect on the Nak-dong River sands, with different .elative densities $(D_r)$, consolidation stress ratios $(K_c)$, and consolidation times. As a result of the tests, it was proved that the undrained cyclic shear strength $(R_f)$ increased with the aged time on the sands. The in situ range of Rf on the sands, which is applicable to the magnitude of earthquake in the Nak-dong River area, was proposed by using the test results.

  • The purpose of this study was to examine the effects of relationships with family on successful aging according to the four attachment style to children. 509 elderly people over 60 years old having a spouse, non-cohabitated children were included. The main findings through this study are as follows; First, secure and preoccupied attachment style were statistically higher than dismissing and fearful attachment style in successful aging and relationship with spouse, children and grandchildren. Second, total paths of research model were different according to the attachment style of the elderly. Model fit of secure attachment style was not good and the effects of relationships with family on successful aging were not statistically significant. In case of preoccupied attachment style, the effect of relationship with spouse and grandchildren on successful aging were significant. Also the effect of relationship with spouse on relationship with children was significant and the effect of relationship with children on relationship with grandchildren was significant. Relationship with grandchildren mediates the effect of relationship with children on successful aging. In case of dismissing attachment style, the effect of relationship with spouse and grandchildren on successful aging were significant. Also the effect of relationship with children on relationship with grandchildren was significant. Relationship with grandchildren mediates the effect of relationship with children on successful aging. In case of fearful attachment style, the effect of relationship with spouse and grandchildren on successful aging were significant. Also the effect of relationship with spouse on relationship with children was significant and the effect of relationship with children on relationship with grandchildren was significant. Relationship with children mediates the effect of relationship with spouse on successful aging. This study explains the role of attachment styles as moderation variable of relationship with family on successful aging and also suggests the importance of marital and grandparents-grandchildren relationship as alternative supporter when the elderly has relational problems with adult children.

  • The effect of aging treatment on the microstructure and mechanical properties of super duplex stainless steel with W was investigated. The phase was precipitated mainly at the early stage of aging and a lower aging temperature under $750^{\circ}C$, but the phase was formed after long-term aging treatment between $600^{\circ}C$ and $900^{\circ}C$. The volume fraction of the phase increased with aging temperature up to $750^{\circ}C$ and then decreased up to $900^{\circ}C$. With an increase in the aging time, the volume fraction phase at the early stage of aging increased slightly, and then increased rapidly beyond a certain time. The rapid increase in the tensile strength and hardness and decrease in the elongation and impact toughness were measured with aging temperatures up to $750^{\circ}C$. On the other hand, the tensile strength and hardness decreased slightly, and the elongation and Charpy impact toughness were unchanged with aging temperatures over $750^{\circ}C$. The tensile strength and hardness increased rapidly at the early stage of aging, and then increased slowly beyond a certain time. The elongation and Charpy impact toughness decreased rapidly at the early stage of aging, and then remained unchanged beyond a certain time. The phase that formed at the early stage of aging and the lower aging temperature had a considerable effect on the elongation and Charpy impact toughness of the super duplex stainless steel with W.

  • Recent clinical studies have shown that computer navigation for total knee arthroplasty (TKA) provides improved component alignment accuracy. However, femoral stress fracture after computernavigated TKA have been reported due to the pin hole and we hypothesized that osteoporosis would be one of the key factors in pin hole fracture after computer-navigated TKA. We investigated the von-Mises stress around the femoral pin-hole for different elastic modulli and ultimate stresses and four different pin penetration modes to understand the aging effect on femoral stress fracture risk after computer-navigated TKA by finite element analysis. In this study, aging effect was shown to increase the femoral stress fracture risk for all pin penetration modes. Especially, aging effect was shown dramatically in the transcortical pin penetration mode.

  • It has been investigated about aging theory. However, aging mechanism still remains to be unknown. Aging and aging related diseases might be due to oxidative damage and these were modifiable by genetic and environmental factors. For designing an optimal medical treatment and countermeasure against aging and aging related disease, it is necessary to understand the aging mechanism. Acetylcholine(Ach) plays an important role in memory. If someone doesn't have enough Ach, he has a tendency to catch a Alzheimer's disease. Corydalis tuber has been clinically used to treat heart disease, gastrointestinal disease and other diseases including endocrine disease in Oriental medicine. The purpose of this article is to investigate the inhibitory effect on Acetylcholinesterase and scavenging effects on NO, DPPH of Corydalis tuber Acua-acupuncture solution(CTAS). The results are summerised as follows; 1. There is a significant inhibitory effect of $0.01mg/m{\ell}$ CTAS group at 20, 30, 60 minutes and $0.1mg/m{\ell}$ CTAS group at 10, 20, 30, 60 minutes on AchE. 2. There is no significant scavenging effect of CTAS on NO. 3. There is a significant scavenging effect of $0.1mg/m{\ell}$ and $0.01mg/m{\ell}$ CTAS group at 10 minutes but there is no significant scavenging effect at 20, 30, 60 minutes on DPPH. There is a significant scavenging effect of $1mg/m{\ell}$ CTAS group at 10, 20, 30, 60 minutes on DPPH.
