This study was undertaken to investigate the factors that influence post-traumatic growth in patients with breast cancer. The study subjects were 100 outpatients with breast cancer who visited the outpatient clinic of a university hospital. The instruments used for this study were Korean Post-traumatic Inventory (K-PTGI), Modified Medical Outcomes Study Social Support Survey (mMOS-SS), Self-Efficacy Scale for Self-Management of Breast Cancer (SESSM-B) and Cancer Coping Questionnaire (CCQ). The data were analyzed by t-test, ANOVA, Pearson-correlation coefficient, and stepwise multiple regression using SPSS/WIN 21.0. The mean score of post-traumatic growth was $3.4{\pm}0.9$ out of 5. Post traumatic growth had statistically significant correlation with social support, breast cancer self-management self-efficacy, and coping behavior. In stepwise multiple regression analysis, post-traumatic growth was significantly influenced by therapeutic compliance related self-efficacy and positive reframing coping behavior and it was account for 29% of the total variance. These results suggest that these influencing factors should be considered in developing the nursing intervention to improve the post-traumatic growth in patient with breast cancer.

To secure the mechanical strength of porous Al₂O₃ ceramics, which can be utilized for filters and catalyst supports is essential for their functionality and durability. Superior mechanical strength would be obtained by tailoring the densification and grain growth during sintering. This study deals with grain growth behavior of a freeze-casted Al₂O₃ with addition of La₂O₃. In a temperature range between 1400 and 1600℃, variations of average grain size with sintering time and temperature were observed and analyzed with G_tⁿ-G₀ⁿ = kt and with k = k₀exp(-E_a/RT). As a result, n value and activation energy (E_a) for grain growth were calculated as 3 and 489.09 kJ/mol, respectively. These commonly confirms retardation effect of the La addition during sintering of Al₂O₃ porous structure. More accurate analysis on the La effect can be followed to provide useful guidance for the selection of additives for better mechanical strength in Al₂O₃ porous structures.

In our society, consumers and enterprises work in cooperation for the continuous development and growth of society as well as construct effective and ethical measures. One of the representative examples are customercentered management activities in corporations, social responsibility activities, and sustainable ethical consumption that show consideration for the consumer's environment. The ethical consumption behavior of consumers becomes a virtuous circle that influences other consumer's ethical decision making by creating an ethical consumption culture. Furthermore, the cost and effort to solve non-ethical consumption problems can be solved. This research aims at aspiring the perception of consumer's ethical consumption and finding measures to increase ethical behavior. This paper further investigated the consumer's ethical consumption behavior, personality traits, perception of consumption society, and ethical judgements. For the research, a structured survey was conducted on 300 university students in Seoul. SPSS ver. 21.0 and AMOS ver. 18.0 programs were used for statistical data analysis. The results indicated differences in variables that influence consumer's ethical consumption behavior (fair trade, boycotts, and environmentally friendly products). In particular, it was evident that ethical judgements (such as the agent, personality traits, and perception consumption society) have different direct and non-direct influences on ethical consumption behavior. Strengthening the management of factors that influence measures that increase university student's ethical consumption behavior in direct and non-direct ways, providing education and improving information are believed effective in increasing ethical consumption behavior.

Key factors enhancing transfer behavior of training and knowledge sharing are of great interest to researchers and executives because training transfer and knowledge sharing activities are remarkable predictors of organizational growth. This study investigates the core motivations for boosting transfer behavior of training and knowledge sharing. To empirically test the impacts of employee training, servant leadership and self-efficacy, a survey was conducted in small-medium sized companies. The data (N=292) were analyzed using structural equation modeling analysis. The results indicate that higher employee training positively leads to self-efficacy and transfer behavior of training. Servant leadership is positively leads to self-efficacy, transfer behavior of training, and knowledge sharing. Self-efficacy of employees induces greater transfer behavior of training and knowledge sharing. Finally, transfer behavior of training encourages workers to increase knowledge sharing. This study represents an initial step to examine the psychological mechanism of improving employees' transfer behavior of training and knowledge sharing activities based on the employee training qualities and servant leaderships.

The growth of solid particles in TiC-XC-2vo1.% and TiC-XC-30vo1.% Ni alloys, (where X=Zr, W or Mo) was fitted to the equation of the form $d^3$-${do}^3$=Kt during the liquid phase sintering at 1,673K. Also, the grain growth behavior decreased markedly with the addition of ${MO}_2$C or WC and increased with the addition of zrC. The contiguity was greater in the alloys with a smaller growth rate constant and especially, decreased by increasing the Ni content in the TiC-${MO}_2$C-Ni alloy. In addition, the effect of the addition of carbide on the grain growth of 2 vo1.% Ni alloys was found to be similar to that of 30vo1.% Ni alloys. Consequently, the grain growth mechanism cannot be explained by the usual solution / reprecipitation process, but can be explained in terms of a new growth velocity equation, which includes the effects of contiguous carbide grain boundaries in restricting the overall grain growth, as well as the area of the solid / liquid interface in the alloy.

The use of fracture mechanics has traditionally concentrated on crack growth under an opening mechanism. However, many service failures occur from cracks subjected to mixed-mode loading. Hence, it is necessary to evaluate the fatigue behavior under mixed-mode loading. Under mixed-mode loading, not only the fatigue crack propagation rate is of importance, but also the crack propagation direction. In modified range 0.3$\leq$a/W$\leq$0.5, the stress intensity factors (SIFs) of mode I and mode II for the compact tension shear (CTS) specimen were calculated by using elastic finite element analysis. The propagation behavior of the fatigue cracks of cold rolled stainless steels (STS304) under mixed-mode conditions was evaluated by using K$\_$I/ and $_{4}$ (SIFs of mode I and mode II). The maximum tangential stress (MTS) criterion and stress intensity factor were applied to predict the crack propagation direction and the propagation behavior of fatigue cracks.

This study examined college students' environmental knowledge, attitudes as well as their behaviors in Busan. Among four areas (biodiversity, carbon cycle, ozone, and global warming) of environmental knowledge, students represented the most understanding on global warming, and the least understanding on biodiversity. In regards to environmental attitude, students represented the lowest scores in reality of limits to growth, and the highest scores in antianthropocentrism. With respect to environmental-friendly behavior, less than 30% of students responded that they always tried to use less paper towels. In addition, only 24% of students responded that they always recycle e-waste. These college students did not represent gender difference in environmental knowledge, attitude as well as behavior. Moreover, there was a strong relationship between environmental knowledge and attitude, while no relationship between environmental knowledge and behavior as well as between environmental attitude and behavior.

This study examined patterns of delinquent behavior trajectory from late childhood to early adolescence and examined relationships between patterns of trajectory and individual, family, and school factors. Youth delinquent behavior trajectories were examined by mixed growth models using data from the 2nd to 5th year surveys of the Seoul Panel Study of Children. Relationships between patterns and effect factors were examined by multinominal logit models. Four patterns emerged: non-delinquency (80%); rapidly accelerating delinquency (3.3%); decelerating delinquency (6.0%); and moderately accelerating (10.7%) groups. Contacts with a delinquent peer group had persistent effects on more serious delinquent behavior trajectories. Increased levels of self-esteem and school achievement prevented increase in delinquent behaviors; close relationships with parents and parental supervision caused decrease in delinquent behaviors.
