This study, targeting a cancer patient undergoing radiation treatment, conducted this research with the aim of looking into the relevance between family support belonging to a patient's primary environment, social support consisting of medical personnel, and the quality of life; this study set 199 patients available for investigation from Jan. 25, 2012 until April 30, 2012 as research subjects among the cancer patients undergoing radiation treatment at the Radiation Oncology Department of a university hospital located in Seoul Metropolitan City. In the analysis of collected data, this study conducted t-test using SPSS/WIN 18.0 Statistical Program, and looked into the relevancy between independent variables including social support, and the quality of life as a dependent variable using analysis of variance, correlation analysis and multi-regression analysis. Conclusively, it was found that the higher the family support perceived by a cancer patient undergoing radiation treatment, the higher the quality of his/her life; thus, this study could learn that there exists a significant relation between family support and the quality of life. Accordingly, it is thought that it's necessary to develop an intervention strategy which makes it possible to intensify family support and social support, etc. for the purpose of improving the quality of life of cancer patients undergoing radiation treatment; further, this study thinks that it's necessary to do additional research which could analyze diverse aspects by subdividing the future quality of life by area.

This study examined how much Korean male middle school students used YouTube to determine if the social support from parents, teachers, and friends might moderate the relationships between YouTube overuse and internalizing and externalizing problems. Three hundred and twenty male middle school students completed questionnaires asking about their YouTube use, levels of YouTube addiction, internalizing and externalizing behaviors, and the degree of social support from parents, teachers, and friends. The results indicated that the YouTube addiction was positively related to the levels of internalizing and externalizing problems. Parental support moderated the relationships between YouTube addiction and internalizing problems. On the other hand, the moderating effects of teachers' or friends' supports were not significant. In contrast, teachers' support was the most crucial moderating factor regarding externalizing problems, while parental and friends' supports were only related to delinquency but not to aggression. These results suggest that the role of parental or teacher supports should be unique depending on the types of problem behaviors. Furthermore, the 'protective effects' of social support were not found in the highly addicted group, suggesting that the early prevention of YouTube overuse is a crucial intervention.

Pile or column supported embankments have been increasingly employed to construct highway or railway embankments over soft soils. Piles or columns of stiffer material installed in the soft ground can provide the necessary support by transferring the embankment load to a firm stratum using a soil arching. However, there has been reported to occur a relatively large differential settlement between the piles and the untreated soils. Geosynthetic reinforced pile or column supported embankment (GRPS) is often used to minimize the differential settlement. Two dimensional finite element anlyses have been performed on both the column supported embankments and the geogrid reinforced column supported embankments by using a PLAXIS 2D to evaluate the soil arching effect. Based on the results obtained from finite element analyses, the stress reduction ratio decreases as the area replacement ratio increases in the column supported embankments. For the geogrid reinforced column supported embankments, the geogrid reinforcemnt can reduce differential settlements effectively. In additon, the use of stiffer geogrid is appeared to be more effective in reducing the differential settlements.

Reliability between safety factor and reliability index for driven and bored pile load capacity was analyzed in this study. 0.1B, Chin, De Beer, and Davisson's methods were used for determining pile load capacity by using load-settlement curve from pile load test. Each method defines ultimate yield and allowable pile load capacities. LCPC method using CPT results was performed for comparing results of pile load test. Based on FOSM analysis using load factors, it is obtained that reliability indices for ultimate pile load capacity were higher than those of yield and allowable condition. Present safety factor 2 for yield and allowable load capacities is not enough to satisfy target reliability index $2.0{\sim}2.5$. However, it is sufficient for ultimate pile load capacity using safety factor 3.

Although numerous investigations have been performed over the years to predict the behavior and bearing capacity of piles, the mechanisms are not yet entirely understood. The prediction of bearing capacity is a difficult task, because large numbers of factors affect the capacity and also have complex relationship one another. Therefore, it is extremely difficult to search the essential factors among many factors, which are related with ground condition, pile type, driving condition and others, and then appropriately consider complicated relationship among the searched factors. The present paper describes the application of Artificial Neural Network (ANN) in predicting the capacity including its components at the tip and along the shaft from dynamic load test of the driven piles. Firstly, the effect of each factor on the value of bearing capacity is investigated on the basis of sensitivity analysis using ANN modeling. Secondly, the authors use the design methodology composed of ANN and genetic algorithm (GA) to find optimal neural network model to predict the bearing capacity. The authors allow this methodology to find the appropriate combination of input parameters, the number of hidden units and the transfer structure among the input, the hidden and the out layers. The results of this study indicate that the neural network model serves as a reliable and simple predictive tool for the bearing capacity of driven piles.

Lateral earth pressure and horizontal displacement of the diaphragm walls constructed in multi-soil layers were analyzed by the field instrumentation from six building construction sites in urban area. The distribution of the developed earth pressure of the anchored diaphragm walls during excavation shows approximately a trapezoid diagram. The maximum earth pressure of anchored diaphragm walls corresponds to $0.45{\gamma}H$ and the earth pressure acts at the upper part of the walls. The maximum earth pressure is two times larger than the empirical earth pressure of flexible walls in sands suggested by Terzaghi and Peck(1967), Tschebotarioff(1973), and Hong and Yun(1995a). The horizontal displacement of diaphragm walls is closely related with supporting systems such as struts, anchors, and so on. The horizontal displacement of anchored walls shows less than 0.1 percent of the excavated depth, and the horizontal displacement of strutted walls shows less than 0.25 percent of the excavated depth. Therefore, the restraining effect of horizontal displacement to the anchored diaphragm walls is larger than the strutted diaphragm walls. In addition, since the horizontal displacement of the diaphragm walls is lower than the criterion, $\delta=0.25%H$, used for control the anchored retention wall using soilder piles, the safety of excavation sites applied with the diaphragm walls is pretty excellent.

The purpose of this study was to examine if there was difference of psychological well-being in mid adulthood on experience of life events and social support in pre-adulthood and the effects of life events and social support in pre-adulthood on psychological well-being in mid adulthood fromlife course perspective. The data came from 511 mid-life adults aged from 40 to 59. The main results were as follows: (1) middle aged who were experienced life events concerning school, parent, violence, and death in pre-adulthood showed lower psychological well-being than those who didn't experience life events in pre-adulthood. Psychological well-being of middle aged who received social support in emotional, material, and informational area in pre-adulthood was higher than one of the whom didn't receive social support in pre-adulthood. (2) the experienced life events concerning parent, violence, and death in pre-adulthood effect on psychological well-being in mid adulthood. Also, the received emotional support and informational support in pre-adulthood influence on psychological well-being in mid adulthood. And there were adjusting effects of life events concerning parent and received informational support in pre-adulthood on the psychological well-being in mid adulthood. These findings support life course perspective that past experiences have cumulative and interconnected effect and the individual life was closely connected with other people having meaningful relationships. Also, the intervention on psychological well-being requires not only prevent life events but augment social support that can protect after experience of life events. The intervention should suggest suitable and specific method on life events.

This study investigated the mediating effects of social support and coping on the relation between traumatic event type, posttraumatic growth and wisdom by the data from 247 adults by using path analysis. Besides, the difference of the level of posttraumatic growth and related variables between traumatic event type groups. At first, The results of the MANCOVA, person-related traumatic event group were higher than the non-personal traumatic event group in negative coping and trauma stress level, and lower in social support, positive coping, posttraumatic growth and wisdom. The path analysis results shows that traumatic event type was related to wisdom by mediate factors. Traumatic event type affected wisdom through social support, positive coping, posttraumatic growth. The significant mediators were social support, positive coping, posttraumatic growth. Negative coping was not a significant mediator between event type and posttraumatic growth. The results show that non-personal traumatic event group are tends to have high level of social support, positive coping, posttraumatic growth, and wisdom. In the end, we described that the implication and the limitation of this study and suggestions for following studies.

This study examined the relationship among temperament, social support and hope of institutionalized children. A total of 198 children, aged 10 to 13, recruited from 20 institutions in Seoul participated. Demographics, temperament, social support from friends, institution-family and school teacher, and hope were assessed by self-report. Results showed that in bivariate level, temperament and social support were significantly associated with level of hope. However, hierarchical multiple regressions indicated that children's hope was predicted only by age and social support from friends, institution-family and school teacher. That is, temperament was not contributed to predict hope, whilst social support contributed unique variance to the prediction of hope, controlling for age. The more social support the children felt they had, the higher levels of hope they reported. Further analyses revealed that support from friends, institution-family and school teacher were influential factors in explaining hope agency, while support from institution-family and school teacher were influential factors in explaining hope pathway of institutionalized children, controlling for age.

The purpose of this study is to understand the relation among health condition of physicalness, psychology and society, family support, and self-integration in age group of old people and to analysis if there are any mediated effect of family support in relationship between health condition and self-integration. For that, the survey was conducted people aged 65 or older living in B city. First, the levels of heath condition of physicalness, psychology and society, and self-integration in 'old people aged between 65 and 74' were high, the level was getting lower in the oldest aged. Second, for the aged groups between 65 and 74, and aged group between 75 and 84, health condition of society and psychology influenced meaningfully with a factor of self-integration, and for the people aged 85 or older, health condition of society and psychology influenced meaningfully. Third, all aged groups had the mediated effect of family support through self-integration in heath condition. Therefore, health promotion for the elderly age group according to a variety of family support intervention and self-integrated sense of improvement in the system by age category providing differentiated services and social assistance strategy is necessary.
