Permeation grouting effectively enhances soil strength and decreases permeability of soil; however, the flow of grout is heavily affected by anisotropy of hydraulic conductivity in layers. Therefore, this study investigates the effect of permeability anisotropy on the effective radius of horizontal permeation grout using computational fluid dynamics (CFD). We modeled the horizontal permeation grout flow as a two-phase viscous fluid flow in porous media, and the model incorporated the chemical diffusion and the viscosity variation due to hardening. The numerical simulation reveals that the permeability anisotropy shapes the grout bulb to be elliptic and the dissolution-driven diffusion causes a gradual change in grout pore saturation at the edge of the grout bulb. For the grout pore saturations of 10%, 50% and 90%, the horizontal and vertical radii of grout bulb are estimated when the horizontal-to-vertical permeability ratio varies from 0.01 to 100, and the predictive model equations are suggested. This result contributes to more efficient design of injection strategy in formation layers with permeability anisotropy.

Nowadays to thrive on the intensively competitive environments based on drastic and rapid technical evolutions, exporting manufacturing companies need to keep very stable relationship with suppliers. Thus, analyzing key factors of strengthening relationship with suppliers in a B2B environment is important. In this regard, this study develops a research model to deeply understand key antecedents of relationship strength between B2B companies. Relationship quality was considered as the key factor affecting to the relationship strength. This study considers relationship satisfaction, trust, and relationship commitment as the factors of relationship quality. Moreover, technical service quality and relational service quality were considered to be the antecedents of relationship satisfaction, while communication and information exchange, relationship policies and practices, and opportunistic behavior were regarded as the antecedents of trust. The PLS method was applied for the empirical analysis of 107 companies data. The results indicated that the relationship commitment has a significant impact on relationship strength. Moreover, relationship satisfaction and trust had indirectly impact on relationship strength through relationship commitment. Although the quality of technical service quality had a significant impact on relationship satisfaction, relational service quality did not have a significant impact. While communication and information exchange, relationship policies, and practices had positively significant impacts, opportunistic behavior had a negative impact.

As software transforms the structure of industry, it becomes a key measure in determining market competitiveness. Therefore, various educational efforts have been attempted in Korea to cultivate software professionals to secure software competitiveness. While previous studies had focused mainly on the cognitive effectiveness of software education, the authors tried to focus on affective perspectives. The authors, therefore, aimed to analyze the predictive power of the recognition of software importance and learning flow on affective outcomes, such as efficacy of computational thinking skills, and attitude toward, and satisfaction with, software education. The data were collected from 103 sixth grade students who participated in a software education. Results show that software importance and learning flow had significant predictive power on affective outcomes; Learning flow mediated the relationship between software importance and affective outcomes. This study provides practical implications for improving affective outcomes in the design and implementation of software education.

The purpose of the study is to investigate the convergence comparison of the stress, major satisfaction, career identity, and college adjustment of nursing students according to college admission process and grade. The 349 subjects were studying in the nursing department in the City P. And the data collection was carried out from April 2016 until May 2016. The data analysis was carried out with the frequency, the percentage, the ${\chi}^2$-test, and the ANOVA by using the SPSS 23.0 Program. Regarding the research results, first, there were no significant differences among the entire academic years according to the admission type. Second, regarding all the admission types according to the academic year, there were the significant differences among stress (p=.001), the degree of satisfaction with the major (p<.001), the sense of career path identity (p=.021), and the adaptation to the college life (p<.001). As a result, I propose that, based on these results of the research, as a strategy for reducing the stress and for improving the degree of satisfaction with the major, the sense of career path identity, and the capability to adapt to the college life on the part of the nursing students, a differentiated, customized educational program by type of admission and by academic year should be developed and applied.

With the full liberalization of distribution sector in 1997, both multinational and domestic discount retailers have been competing to gain more market share in Korea. Increased competition among domestic and international retail stores forces marketing academics and practitioners to understand the various factors affecting discount retail store satisfaction and loyalty. This study examines how store image of a retailer influences consumers' attitudes, satisfaction and intention to re visit that store. The data, collected from a sample of 416 customers in Busan, Korea, indicate that store image is exerting positive influences in the formation of attitude, satisfaction. But favorable store image does not have positive impact on the intention to revisit the store. Rather the impact of store image on intention to re visit is mediated by attitudes and satisfaction. And unlike the overall store image, attitudes have positive effect on the formation of consumers' intention to revisit, not mediated by satisfaction. And satisfaction also results in higher possibility of forming intention to revisit that same discount store. Based on these results, we provide theoretical and managerial implications, limitations of this research, and useful directions for future study.

This study purposes to explore the growing process through spousal bereavement in later life, and to develop the theory. A qualitative research was conducted, and the participants were 17 seniors. The analysis according to Strauss and Corbin's grounded theory(1998), resulted in 143 concepts, 43 subcategories, and 19 categories. Range analysis according to paradigm showed that the causal conditions were 'marital relationships', 'independent/dependent tendencies', and 'emotional readiness for the death of a spouse', and the phenomena were 'depression', 'hopelessness', 'daily stress', 'psychological intimidation', 'regret', and 'sense of being freed'. The contextual conditions that affect these phenomena were 'desire for intimate personal relationships' and 'desire to maintain independence'; the action/interaction strategies to manage the phenomena were 'facing reality' and 'efforts for construction of the new life'; and the mediating conditions that promote or suppress these action/interaction strategies were 'social support' and 'spirituality'. The results were 'reconstruction of the meaning in life', 'increase in self-esteem', 'reinforcement of social network' and 'embrace and acceptance'. Furthermore, when personal growth after bereavement of a spouse was analyzed focusing on changes over time, the growth process consisted of three steps: 'sadness and despair', 'embracing and moving forward', and 'personal growth'. The pattern analyses were performed to typify recurring relations by category, and 5 types were derived. The results of our study show that personal growth after spousal loss is an integrative process in life after crisis, and can be conceptualized as the process of overcoming the despair that immediately follows the death of a spouse, seeking a new life by actively taking control, and discovering a strengthened self.

For conservation of biodiversity, we designate and manage the major areas that are habitats of organisms as ecosystem protected areas. It is necessary to evaluate the biodiversity of protected areas relatively in order to establish strategies to protect and secure the biodiversity of protected areas. In this study, we selected evaluation indicators by which we can compare objectively the biodiversity of protected areas corresponding to forest ecosystem, and applied them to Mt. Jiri and Mt. Bukhan National Parks. We reviewed literatures to select evaluation criteria. Frequently mentioned criteria and the structure of the forest which plays an importantrole of forest biodiversity were selected as the evaluation criteria. As the result, the selected evaluation indicators were 7-species diversity, species richness, evenness, rarity, disturbance species, indigenous species, and forest structure. In Mt. Jiri and Mt. Bukhan National Parks, species diversity were 3.492 and 2.943, species richness were 8.998 and 9.793, evenness were 0.849 and 0.680,rarity were 11.976 and 10.783, and disturbance species index were 0.214 and 0.357 respectively. Both national parks had abundant indigenous species and showed various forest physiognomies and stable 4-layer structure. It was found that crown density was higher in Mt. Jiri. Most indicators were implied high biodiversity in Mt. Jiri and Mt. Bukhan national parks.
