Al₂O₃ 다공체는 필터 및 촉매 담체 등으로 활용되며 그 기능성과 내구성을 확보하기 위해서는 다공성 구조의 기계적 강도가 중요하다. 소결 중 치밀화 및 입자성장을 유리하게 제어하는 것이 기계적 강도 향상에 필수적이며, 본 연구에서는 그 일환으로 La을 첨가하여 동결주조로 성형된 Al₂O₃ 다공체의 입자성장 양상을 분석하였다. 즉, 250 ppm의 La을 첨가한 계에서 1400℃에서 1600℃에 이르는 온도 범위 내에서 소결 시간 및 온도에 대한 평균입도 변화를 관찰하여 G_tⁿ-G₀ⁿ = kt 관계로부터 exponent(n 값)은 3으로, k = k₀exp(-E_a/RT)로부터 입자성장에 대한 활성화 에너지(E_a)는 489.09 kJ/mol로 각각 계산되었다. 이러한 결과는 입자성장에 대한 La의 첨가 효과를 나타내며, La이 Al₂O₃의 입계 이동속도를 늦춰 입자성장의 억제에 효과가 있음을 방증하므로 기계적 강도에 이롭다. 한편, 향후 원료 분말에 함께 포함되어 있는 미량의 불순물 작용을 관찰하면 La의 기여를 명확히 구분할 수 있으며, 이러한 접근은 향후 다공성 Al₂O₃에서 입자성장을 제어하는데 사용될 수 있는 첨가제를 선택하는 데 유용하게 사용될 수 있다.

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.
