  • This study examined a model in which the relation between perceived contextual support and career indecision was expected to be mediated by coping self-efficacy and outcome expectancy for a sample of engineering students (N = 672). Structural equation analyses revealed that the link between contextual support and career indecision was fully mediated by coping self-efficacy and outcome expectancy. Statistically significant paths were found from contextual support to coping self-efficacy and outcome expectancy. Statistically significant paths were also found from self-efficacy and outcome expectancy to career indecision. In addition, there were significant gender differences in the mean scores of the variables and model fits. Implications for research and practice are discussed.

  • Recently, accidents involving structural elements, formwork, and shore have occurred continuously during concrete pouring, especially in multistory-shored RC structure systems with non-typical stories with increased slab thicknesses. In previous studies, an analysis was conducted on the stiffness of concrete and distribution of slab construction loads when some slab thicknesses were increased under the same conditions. This study analyzed the construction load, construction damage parameter, and shoring force by varying the construction conditions, such as the construction period and number of shores, as well as the design conditions, such as the thickness increment and number of thickness increment slabs, in a multistory-shored RC structure system with non-typical stories with increased slab thickness.

  • This study examines the moderation effect of social support and acceptance of sexual orientation on the mediation effect of through rumination on the relationship between microaggression against sexual orientation and LGB's depression. To this end, an online survey was conducted among cisgender homosexuals and bisexuals aged 18 years and older, and 380 participants were ultimately selected for the study. The results of the study were as follows. First, the correlations of all variables were significant except for the relationship between rumination and acceptance of sexual orientation. Second, rumination partially mediated the pathway of microagression against sexual orientation predicting LGB's depression. Third, the moderated mediation effect of social support and acceptance of sexual orientation on the relationship between microaggression, rumination, and depression was found. The effect size of social support was found to be larger than that of acceptance of sexual orientation. Based on these findings, the implications of the study, possible interventions in counseling, and suggestions for further research were discussed.

  • Bearing capacity factor $N_{\gamma}$ and shape factor were studied for rigid strip and circular footings with a rough base on sand by numerical modelling considering the effect of dilation angle. The numerical model was developed with an explicit finite difference code. Loading procedures and interpretation methods were devised in order to shorten the running time while eliminating the exaggeration of the reaction caused by the explicit scheme. Using the Mohr-Coulomb plasticity model with associated (${\psi}={\phi}$) and nonassociated (${\psi}$ < ${\phi}$) flow-rules, the bearing capacity factor $N_{\gamma}$ was evaluated for various combinations of internal friction angles and dilation angles. Bearing capacity factor decreased as the dilation angle was reduced from the associated condition. An equation applicable to typical sands was proposed to evaluate the relative bearing capacity for the nonassociated condition compared to the associated condition on which most bearing capacity factor equations are based. The shape factor for the circular footing varied substantially when the plane-strain effect was taken into account for the strip footing. The numerical results of this study showed closer trends with the previous experimental results when the internal friction angle was increased for the strip footing. Discussions are made on the reason that previous equations for the shape factor give different results and recommendations are made for the appropriate design shape factor.

  • Granular compaction piles increase the load bearing capacity of the soft ground and reduce the settlement of fecundation built on the reinforced soil. Also the granular compaction piles accelerate the consolidation of soft ground using the granular materials such as sand, gravel, stone etc. However, this method is one of unuseful methods in Korea. In the present study, the estimation procedure for the ultimate bearing capacity of randomly installed granular compaction pile group is proposed. Also, carbon rod tests have been peformed for verifying the group effect of granular compaction piles and the behavior characteristics such as bulging failure zone on granular compaction piles. From the test results, it is found that bulging failure shape of granular compaction piles was conical shape and the ultimate bearing capacity increased as the spacing of piles became gradually narrow. Also, from the proposed method in this study, the optimal locations of granular compaction piles with various installed cases are analyzed. The results were shown that the bearing capacity was increased in the case concentrated on the central part of pile group.

  • 일반적으로 I형 보에 횡하중이 작용하는 경우, 횡 변위와 함께 회전을 동반하는 횡-비틀림 좌굴(Lateral-Torsional Buckling)이 발생하게 된다. 이러한 I형 보의 탄성 및 비탄성 횡-비틀림 좌굴에 대한 해석적 이론적 연구는 이미 많은 연구자들에 의해 수행되었다(Timoshenko 등, 1961; Galambos, 1963; Lindner, 1974; Trahair, 1993). I형 보의 비지지 길이 내 하중이 작용할 때 모멘트 구배계수(Cb)는 하중이 부재 단면에 작용하는 위치에 따라 달라지게 되는데 이를 하중고 효과(Load Height Effects)라고 한다. 탄성 영역 내 비지지길이가 존재하는 I형 보의 하중고 효과를 고려한 모멘트 구배계수 제안식은 Nethercot & Rockey(1971)에 의해 연구된 바 있다. 또한 Helwig 등(1997)은 Nethercot & Rockey(1971)의 제안식을 간략화 하여 탄성 영역 내 비지지길이가 존재하는 I형 보의 하중고 효과를 고려한 모멘트 구배계수식을 제안하였다. 그러나 현재까지 진행 된 하중고 효과에 대한 연구는 탄성 영역 내 비지지 길이가 존재하는 I형 보에 대한 제안식이며 현재까지 비탄성 영역 내 비지지 길이를 갖는 I형 보의 하중고 효과에 대한 연구는 진행된 바 없다. 본 연구는 비탄성 영역 내 비지지 길이가 존재하는 I형 보의 하중고 효과를 고려한 비탄성 횡-비틀림 좌굴강도에 대한 연구를 수행하였다. 하중조건으로는 집중하중 과 등분포 하중을 적용시켰으며, 비선형 횡-비틀림 좌굴 해석을 위해 잔류응력 및 초기변형을 고려하였다. Pi와 Trahair(1995)이 고려한 단순직선분포를 잔류응력으로 가정하였으며, 국내 I형강 표준 치수 허용치(현대제철, 2006)에 근거하여 부재 길이의 0.1%를 초기 최대 횡 변위로 적용하여 초기제작오차로 고려하였다. 유한요소해석결과를 바탕으로 Nethercot & Rockey(1971)와 Helwig 등(1997)의 연구내용을 바탕으로 범용구조해석 프로그램(ABAQUS, 2007)을 이용하여 비탄성 영역 내 존재하는 I형보의 횡-비틀림 좌굴강도를 산정하였다. 유한요소해석결과를 바탕으로 Nethercot & Rockey(1971)및 Helwig 등(1997)의 모멘트구배계수 제안식과 비교 분석 하였고 회기분석프로그램 MINITAB(2006)을 이용하여 비탄성 영역 내 비지지길이가 존재하는 I형보의 하중고 효과를 고려한 모멘트구배계수식을 개발 제안하였다. 본 연구에서 개발된 제안식은 경제적이고 합리적인 휨부재 강도평가에 적극 활용될 수 있으며, 비탄성 영역내 I형보의 횡-비틀림 좌굴강도 및 휨강도 연구에 널리 활용될 것이다.

  • In this study, the physical and dynamic characteristics of soil were analyzed by selecting 3 sections as research subjects among road and structure construction sections in the construction site of the Gwangyang ${\bigcirc}{\bigcirc}$ industry area, and conducted consolidation analysis and bearing capacity assessments through Midas-GTS according to the construction conditions of the structures and section conditions of reinforcement using stabilized soil. The effects of improving the settlement and bearing capacity according to the improved effects of the stability and sections of reinforcement using stabilized soil in applying the reinforcement method using stabilized soil were analyzed as a solution for improving the settlement and bearing capacity of soft clay for constructing roads and structures. The improvement effects of the settlement and bearing capacity were outstanding when the reinforcement method using stabilized soil to the soft clay was applied. After applying the reinforcement method using stabilized soil, the holdback effect of the consolidation settlement was excellent by decreasing the volume of the consolidation settlement from a minimum of 53% to a maximum of 82%. When the width of the reinforcement using stabilized soil was twice the width of the constructed structure, it was found that the holdback effect of the consolidation settlement ranged from 1% to 7% through the width of reinforcement using stabilized soil. In addition, when applying reinforcement more than 6m in width and 1m in depth using stabilized soil, it was found that the increase in the allowable bearing capacity was 2.3 to 3.3 times more than that before applying the reinforcement, which suggests that the increase in bearing capacity by applying the reinforcement method using stabilized soil was significant.

  • The purpose of this study was to examine the attitude toward own aging among community-residing elderly and the predictors of the attitude focusing on personal resources, social support, and social participation. Data were collected from 198 elders aged 60+ with the cooperation of several social service center for the aged, senior centers, and senior citizen associations in Daejeon Metropolitan City. SPSS 22.0 software was used for descriptive analysis, correlation analysis, and hierarchical regression analysis. The results showed that (1) the research participant elderly's attitude toward own aging indicated fairly negative perception of their own aging; (2) self-esteem and economic status were statistically significant factors indicating the higher levels of self-esteem and economic status predicting the positive attitude of their own aging; (3) emotional support from family was statistically significant factor that predicted the positive attitude of their own aging; (4) the level of social participation was also statistically significantly associated with the positive attitude; (5) In the full model of all independent variables, the significance of emotional support from family and social participation disappeared, but self-esteem and economic status among personal resources remained statistically significant influential factors. Based on the findings, suggestions for social welfare policy and practice to improve community-residing elderly's positive attitude toward their own aging were discussed.
