The purpose of the study is to investigate the impact of resilience and social support on adjustment to college life of freshman and sophomore year college students. 166 college students from two universities in J city were instructed to answer structured questionnaires, and the data was analyzed by T-test, ANOVA, Pearson Correlation, and Regression analysis using SPSS 24.0 software. The results show that resilience and social support have statistically significant positive correlation to adjustment to college life. Variables that affect adjustment to college life are college major satisfaction, grades in the preceding semester, drinking, smoking, positivity(a sub-variate of resilience), and material support(a sub-variate of social support) with explanatory power of 39.6%. The results of this study suggest the need to develop programs that consider resilience, social support, and college major satisfaction in order to support freshmen and sophomores with their adjustment to college life.

As piling works in urban area are increasing, SIP which has low noise & vibration piling method takes the place of driven pile which has good bearing charateristics and is economical. Although SIP has been used far more than 15 years and it's use is increasing year by year, accurate analysis of bearing mechanism of SIP is not enough. So the design of SIP is much more conservative than driven pile. This paper is aimed at analysing the bearing charateristics of 103 SIPs constructed in Korea to give rational design criteria. Research result shows that bearing capacity of SIP is 40% lower than that of driven pile and conservative Meyerhof(20$\bar{N}_b'A_b$) method produced closer result to load test results than any other design method. And this result shows that in order to use optimised design criteria for the economical SIP design, quality control criteria must be settled down to produce high bearing capacity.

The purpose of this study based on descriptive research is to examine the influences on the self-regulated learning ability due to nursing students' achievement-goal and to make sure mediating effect of autonomous support of professor. A convenience sample of 294 nursing students were recruited from a college in C province from April to May, 2018. Data are analyzed using SPSS/WIN 21.0 program. As a result, it is turned out that there are positive correlation between mastery goal, performance approach goal, self-regulated learning ability and autonomous support of professor. In the Sobel test results, autonomous support of professor had a partial mediating effect between mastery goal and self-regulated learning ability(Z=3.922, p<.001). So, a new teaching method should be developed through the convergence of related factors of self - regulated learning ability.

Model pile tests, using a calibration chamber in which the stress state and the relative density can be controlled, were performed in order to study the effects of pile diameter on the plugging rate and bearing capacity of open-ended pile. The model piles used in the test series were devised so that the bearing capacity of an open-ended pile could be measured out into three components. The test results showed that fully plugging depth of an open -ended pile increased with increase in pile diameter and soil density. Moreover, it was found that unit plug capacity decreased with increase in pile diameter, though the penetration ratio or plugging rate of piles was constant. However, the existing formulae for estimation of plug capacity give plug capacity which is constant or increased with increase in pile diameter, when penetration ratio or plugging rate of piles is equal. Thus, it is proposed that the effect of pile diameter as well as plugging rate on bearing capacity of pile must be considered in plug capacity estimation.

This study also examined the influence of academic stress on major satisfaction of college students and the influence of self-efficacy and social support. The subjects of this study were 320 students attending K university in B city. The 295 questionnaires were collected and 291 questionnaires were finally analyzed except for 4 questionnaires that were insufficient. Major satisfaction had a statistically significant negative correlation with academic stress, and major satisfaction had a statistically significant positive correlation with self-efficacy. Also, major satisfaction had a statistically significant positive correlation with social support. Finally, as a result of examining the effects of each factor, academic stress, self-efficacy, and social support had a significant effect on major satisfaction except for informational support in social support. In order to increase the satisfaction of college students, it is necessary to study the factors that can lower academic stress and develop the program accordingly. It is necessary to develop educational methods and programs that can increase self-efficacy and social support. This is considered to have a positive effect on the satisfaction of college students.

To increase the bearing capacity of existing auger-drilled piles and decrease the noise and vibration during the installation of the piles, Spirally-reamed and Under-reamed auger trilled piling methods were developed. Field tests were performed to verify the inurement degree of bearing capacity and the constructional possibility of the new augerdrilled piling methods. The test results showed that the bearing capacity of the new augertrilled piles was fairly improved by the grooves of piles, and the skin friction was affected by the groove height and spacing between grooves. It was found that the skin friction takes the great part of total bearing capacity in auger drilled Biles, i.e. 74~80% in case of the existing methods and 81~86% in case of these methods. Moreover, the settlement of spirally-reamed and under reamed piles was smaller than that of the existing augerdrilled pile for the same loading state.

Pile-supported embankment is one of the reinforcing methods to minimize damage due to the severe subsidence and lateral flow when soft clay ground is supported with embankment. pile-supported embankment mainly penetrates soft ground into the bearing stratum in order to support surcharge load which minimizes the subsidence and lateral flow due to the surcharge load. The aim of this research is to review quantitatively reinforcing effect of pile-supported embankment which is installed in soft clay ground. From the model test, it reproduced the ground movement with regard to the non-reinforced and reinforcing embankment-pile and also analyzed stabilizing effects of lateral flow due to the pile-supported embankment. With regard to the case of installing pile-supported embankment, its were analyzed stabilizing effects of lateral flow in cases of quick-load and slow-load to make different surcharge load.
