The scour risk assessment was conducted for ultimate limit state of newly developed penta pod suction bucket support structures for a 5.5 MW offshore wind turbine. The hazard was found by using an empirical formula for scour depth suitable for considering marine environmental conditions such as significant wave height, significant wave period, and current velocity. The scour fragility curve was calculated by using allowable bearing capacity criteria of suction foundation. The scour risk was assessed by combining the scour hazard and the scour fragility.

Two large diameter steel cased piles (TS-1 and TS-2) were installed and load-tested with the maximum load of 2000 ton at Kwang-An grand bridge. One of the test piles (TS-1) was socketed into the fresh rock and the other test pile (TS-2) was socketed into the weathered rock. Most loads were carried by the weathered rock layer at the maximum applied load for the test piles. In addition, numerical studies were performed using PENTAGON 3D and ROCKET. Based on this study, the weathered rock layer provided sufficient side resistances and possibility of an alternative embedded layer if weathered rocks are deeply layered over fresh rock, which caused difficulties and cost in construction.

Rock socketed drilled shafts are used as foundations for bridges and other transportation structures because of their load carrying capabilities. However, only limited information is available in the literature on the effects of roughness on the unit side resistance of rock socketed drilled shafts. The objective of this study is to investigate the effect of drilling tools on the socket roughness in soft clay shale in Texas. Field study showed that the drilling tools, auger and core barrel, produced different roughness in the boreholes.

The main problem with roads is that cracks and settlement occur over time due to loads acting from the surface layer. One way to solve this problem is to use Geocell. Geocell can be used for structural reinforcement for erosion prevention, ground stabilization on flat and steep slopes, load bearing, and ground preservation. In this study, analyzed road pavement application cases using Geocell and purpose of this study is to analyze the bearing capacity of a road paving method including Geocell using field tests and LFWD(Light Falling Weight Deflectometer) equipment. In addition, the bearing capacity was compared and analyzed with the existing traditional road pavement method.

In this study, artificial neural network is applied to the evaluation of bearing capacity of the PHC auger-drilled piles at sites of domestic decomposed granite soils. For the verification of applicability of error back propagation neural network, a total of 168 data of in-situ test results for PHC auger-drilled plies are used. The results show that the estimation of error back propagation neural network provide a good matching with pile test results by training and these results show the confidence of utilizing the neural networks for evaluation of the bearing capacity of piles.

The purpose of this study was to examine the effects of mothers' parenting beliefs and supportive interaction on maternal parenting stress. It also examined variations of the results by household income levels and mothers' employment status. Participants of the study were 770 mothers of children aged 23-31 months who were a part of the 2010 wave of the National Survey for Panel Study on Korean Children. The analyses revealed that parenting stress was affected by mothers' parenting beliefs and supportive interaction. Mothers' supportive interaction has been shown significantly to predict parenting stress in all four groups of this study. The results demonstrated that the strength of the relationship between parenting stress and parenting beliefs and reciprocal interaction varied based on the combination of income and work status. These findings suggested that income and employment status are important to examine collectively.

This study distinguished game use groups by considering adaptive game use and maladaptive game use of middle school students at the same time, and analyzed the difference in lack of self-control, peer-support, and game usage by group. To this end, the data of 287 middle school students was analyzed in the Game User Panel Survey(5th year) of the KOCCA. As a result of the cluster analysis, the game use groups were divided into the high level coexist group, the adaptive use group, and the normal group. The three groups showed the gap of lack of self-control, peer-support, and game usage.

This study aims to clarify the socio-economic factors which have an effectiveness on the social support in rural areas and analyze how it relates to the Individual Health promotion behavior. It is advised to improve social support in the community. The target population was all residents with no chronic and no serious disease who live in five villages of Chuncheon in Kangwon province during July of 2002. This study was done by the interview survey using questionnaire which was composed with questions about Medical Outcomes Study-Social Support Survey(MOS-SSS) and the health promotion behavior. MOS-SSS was translated to Korean and modified to be suitable for the study. The functional and social support variables were also added. The health promotion behavior was formed through the questions about whether or not stop smoking, stop drinking, the excise, the health examinations, attending health education, and hormone replacement therapies. The results are as follows; 1) the case of low-educated, divorce or separation to death, or the subject of social assistance, the social support was low. 2) the case of high social class, the social support was high. 3) there were no significant findings in the health status. 4) according to the analysis of correlation of health promotion behavior, the group with the most social support showed a high percentage of getting health examinations, attending health education, Hormone replacement therapies. However, the adjusted rate of smoking and drinking of trying to stop smoking and stop drinking resulted in low figures. The well-structured social support which the community can provide should be firstly given a priority for the group with low-income, low-educated, divorce or separation to death, and social assistance who are provided poor social support. Moreover, the social support service should be actively reflected to the health promotion program in the community.

In this study, a prediction model for depression among parents with disabled children was developed by verifying the effects of social support and family resilience. One hundred forty one parents with disabled children were recruited from three out-patient clinics of rehabilitation hospitals in D city between August and September, 2014. The instruments used were the QRS, CES-D, MSPSS, and KFSS-II. The average score of depression was 20.18/60. The levels of depression were significantly different among variables, e.g., sex, age, and monthly income. The mean scores of the item for social support and family resilience were 3.11/5 and 3.32/5, respectively. Family resilience differed significantly according to monthly income. Parental depression was negatively correlated with the social supports and family resilience. Social support was correlated positively with family resilience. In conclusion, family resilience and social support are predictable factors for depressed parents with disabled children.

This study aimed to investigate the role of social support to enhance posttraumatic growth in the Family Caregivers focusing on their trauma by development of the elderly with dementia. The study subjects were 204 family Caregivers for the elderly with dementia and the data were analyzed by the gender. This study utilized IBM SPSS Statistics ver. 20.0 for analysis, and the main results of this study were as follows. First, female group of the family Caregivers showed significantly higher in the level of trauma while male group showed significantly higher in the informal areas of social support and posttraumatic growth. Second, female group showed the protective effect in the formal area of social support and male group did the effect in the formal and informal area of social support. As such, this study investigated the level of trauma by gender of family Caregivers for the elderly with dementia and suggested the implementation strategies to enhance posttraumatic growth. Moreover, this study has the meaning to provide the required fundamental data to establish proper community care upon demonstrating the practical analysis results considering the characteristics of social support.
