In the analysis of early-age concrete behavior, the fresh concrete is considered as a structural element immediately after mixing. But for the activation of real structural behavior in the fresh concrete, the so-called setting time is necessary a few hours after the beginning of hydration reaction. In this paper, analysis on the setting behavior is carried out by proposing an analytical model based on the percolation theory as well as the expanding cluster model by defining the setting as a microstructure formation in fresh concrete. An experimental investigation is also carried out to show the influences of curing temperature, mineral admixtures and chemical admixture on setting behavior of fresh concrete. Finally, the analytical results using proposed model are compared with the experimental results for the sake of verification.

본 연구는 4년제 대학생의 취업준비행동에 있어 취업목표설정이 어떠한 영향을 미치는지 알아보고 어떠한 취업준비행동이 취업목표달성에 영향을 미치는지 검증하고자 한국고용정보원에서 제공하는 대졸자 직업이동 경로조사(GOMS) 중 '2011GOMS1'을 활용하였다. 분석결과 취업목표를 설정한 경우가 취업목표를 설정하지 않은 경우보다 취업준비행동에 더 적극적인 것으로 나타났으며 취업목표달성에 영향을 미치는 취업준비행동으로는 경력개발프로그램 중 직장체험프로그램이 정(+)적인 영향을, 진로 및 취업교과목이 부(-)적인 영향을 미쳤다. 이번 연구를 통해 목표설정유무는 취업준비행동에 긍정적으로 기여함을 확인하였다. 하지만 목표설정이 취업준비행동을 유발하지만 이것이 곧 목표달성을 가져 오는 것이 아니므로 대학생들이 합리적인 진로목표를 설정할 수 있도록 하는 상담 및 프로그램 운영과 함께 체계적인 취업교과목 운영, 직장체험의 기회 확대해야 할 것이다.

This study examined the effect of Behavior Based Safety(BBS) program on safe behaviors of bus drivers and passengers. Four male bus drivers working at a H transportation company situated in Seoul participated in this study. BBS program consisted of education, prompts, and self-monitoring with goal setting. Dependent variables were the percentage of two safe driving behaviors of bus drivers (departure after stopping for 3 seconds, announcement for holding bus handles) and the percentage of one safe behavior of passengers getting on the busses those drivers drove (holding bus handles). A primary observer and two trained assistant observers measured two safe behaviors of the bus drivers with behavior checklists by riding on the busses and the passengers' safe behavior was observed by CCTV installed on each bus. An ABC multiple baseline design across participants was adopted. After baseline(A), education and prompts(B) and self-monitoring with goal setting(C) were introduced sequentially to each participant. The results showed that BBS program was effective to increase both bus drivers' and passengers' safe behaviors. Especially self-monitoring with goal setting was more effective in improving safe behaviors of bus drivers than education/prompts. These results suggest that education/prompts and self-monitoring with goal setting would be an alternative treatment technique to improve safety for lone workers such as bus drivers.

The so called setting is defined as the onset of rigidity in fresh concrete. In the analysis of the early-age concrete behavior, we consider fresh concrete as a structural element immediately after mixing. But for the activation of real structural behavior of fresh concrete, it takes some time after the beginning of hydration reaction. So, the very early age deformations due to hydration heat and shrinkage which occur before the setting do not produce restraint stresses. In this paper, we propose a setting characteristic model based on the so called percolation theory. From the analysis using the model, the influence of curing temperature is investigated and analytical results are compared with experimental results. From the comparison, the validity of proposed model is verified. This model is also applied to evaluate stress development in a temperature-stress test machine (TSTM) specimen and then the effect of setting time on the stress development is discussed.

By providing a number of unprecedented knowledge sources, virtual communities have stimulated interests in knowledge sourcing Specifically, virtual communities have triggered fundamental changes in the ways that people interact with one another. Thus, there is a critical need to examine how people try to behave for sourcing knowledge in virtual communities, particularly in terms of the demand-side perspective of knowledge. To address the knowledge gap regarding knowledge sourcing behavior from the knowledge recipients' side, this study draws upon GPA(goal-plan-action) theory with both the social cognitive theory and the goal-setting theory as overarching theories. Furthermore, we apply past experience in virtual communities and trust in knowledge providers as moderating variables to deeply understand the knowledge recipients' behavior. We expect to present theoretical and practical implications through our findings, which are relevant to cognitive goal-setting and knowledge sourcing behavior. In the theoretical perspective, this study illustrates how knowledge recipients determine knowledge sourcing behavior. Based on our findings, this study has practical implications for virtual communities to effectively balance knowledge repositories and knowledge management systems with knowledge providers and recipients.

The electro-mechanical impedance(EMI) behavior of piezoelectric sensor embedded in cement mortar was investigated to assess the setting times. EMI signal was continuously measured for 12 hours by the PZT sensor embedded in cement mortar with different ratio of sand. As a result, the setting times by the penetration resistance test were accelerated as the sand ratio increased. However, the setting times by EMI sensing technique were delayed as the sand ratio increased.

This study explores the differences in product evaluation and approach behaviors as well as the effects of product evaluation on approach behaviors of utilitarian and hedonic products in on-line and off-line settings. A total of 332 subjects participated in the experiments to assess product evaluation and approach behaviors for utilitarian and hedonic clothing products in on-line and off-line settings. The results show that even though the same stimulus was presented, consumers' product evaluation of utilitarian clothing (i.e., t-shirts) was higher in the off-line setting than in the on-line setting while the approach behavior of hedonic clothing was better in the on-line setting than in the off-line setting. In addition, color was a crucial factor generating positive approach behaviors for utilitarian clothing while style and quality were core factors influencing the approach behaviors of hedonic products in an on-line setting. There was no consistency in the results of the important factors affecting approach behaviors of utilitarian and hedonic clothing in an off-line setting. The conclusion suggests implications for marketing based upon the results of this study.

Purpose: This study was conducted to develop a self-management program using goal setting for patients after a stroke. The program was based on a theory-based Goal setting and Action Planning framework (G-AP), and the effectiveness of the program was examined. Methods: A non-equivalent control group pretest-posttest design was used. The experimental group (n=30) received the self-management program using goal setting based on the G-AP over 7 weeks. The education was delivered individually with a specifically designed stroke workbook. The control group (n=30) received only patient information leaflets about stroke. Results: There were significant differences between the two groups. Stroke knowledge, self-efficacy, and health behavior compliance were significantly higher (all p<.001), and hospital anxiety (p<.001) and depression (p<.001) were significantly lower in the experimental group compared to the control group. Conclusion: This self-management program using goal setting based on a G-AP was found to be useful and beneficial for patients in stroke rehabilitation settings.

Purpose Through the provision of real time performance information about who is contributing and who is not in Electronic Brainstorming, prior studies evidenced a significant performance gain. However, it has been observed that the quantity-based performance feedback alone does not have enough restrictiveness to guide the performance behavior throughout the idea generation session. We included the notion of goal setting into the process performance feedback mechanism in an effort to regulate performance behavior and to better understand why individuals in Electronic Brainstorming are not obtaining enough stimulation benefits in the group interaction process. Design/methodology/approach We had developed real-time visual process performance feedback and modified to include goal setting. This mechanism visually displays individuals' performances two-dimensionally (quality for each idea vertically and quantity of ideas horizontally along with their goals). As individuals' contributions accumulate, the mechanism reveals performance histories by connecting the sequence of ideas in a time-series format, telling stories of individuals' performances. Then, we compared the performance outcome from this study with the outcomes from two prior studies (i.e., Jung et al., 2010 and Jung, 2014). Findings The results showed that the inclusion of goal setting into the process performance feedback solved the issue in the previous study. That was the lower than expected magnitude of performance enhancement of process performance feedback when compared to that of quantity-based feedback. It appears that goals as a motivational technique provide standards for systematic self-evaluation, serving as a cue to regulate performance behavior by strengthening the linkage between effort and performance. Thus, goals seem to set up a self-fulfilling prophecy, preconditioning better performance. However, the outcome still showed that its performance magnitude is unsatisfactory because the outcome of this study turned out to be close to the outcome of just quantity-based performance feedback in Jung et al.'s (2010) study.

The purpose of this study was to analyze the relationship between outdoor play environments and child's play behaviors. The data were collected by this study include field measurement survey, and non-participatory observation from 8 child care centers in Seoul. The field measurement survey were conducted from February 20 to March 20, 2005, whereas non-participatory behavior observation were conducted from June 15 to July 10, 2005. The major results showed the following. 1)Most of child care centers were too small, did not use the adequate surfacing to play various activities, and were made of play equipment setting. 2)Child's play behavior focused on functional play activity and construction play activity. 3)The relationship between outdoor play environments and child's play behaviors showed that small outside play environment with monotonous construction of play setting produced functional play behaviors on children. However, in some cases, despite the small and monotonous play area, diverse play behaviors were observed. These playgrounds at least differed from others in that they provided the place where multi purpose play was possible. This finding shows that multi purpose play areas can be an alternative in small playground environment.
