This study aimed to analyse the effects of a self-regulation group counselling program on self-esteem and self-control in adolescents on probation. In respect to sub-areas of the effects the self-regulation group counselling program had on self-esteem in adolescents, there were statistically significant differences in general self-esteem, social self-esteem and family self-esteem. Also, there were statistically significant differences in all the areas including impulse control and emotional control as sub-areas of self-control. Such results experimentally showed that the self-regulation group counselling program had a significant effect on self-esteem and self-control in adolescents on probation. Therefore, it is expected that the probability of repeating their crimes will decrease greatly if the subjects have self-esteem and self-control enhanced through the group counselling program. It is suggested further studies on the self-regulation group counselling program and its practical use are needed to enhance self-esteem and self-control in adolescents on probation.

Hydration heat and autogenous shrinkage are generated essentially by the same hydration. Many researchers have studied the close relationship between hydration temperature and autogenous shrinkage but hardly any research has been undertaken to explain the specific numerical relation. In this study, early age properties of hydration heat and autogenous shrinkage of specimen whose section size was changed were analyzed, and relationship between hydration heat and autogenous shrinkage was investigated. In the results of the study, inner temperature and autogenous shrinkage increased as the section size increased. And rise and rise ratio of hydration temperature and autogenous shrinkage in hydration heating section and autogenous shrinking section are increased too. Temperature rise and autogenous shrinkage rise increased respectively, as hydration heating velocity and autogenous shrinking velocity increased. And autogenous shrinkage rise and autogenous shrinking velocity increased as hydration heating velocity increased.

This research purposed to verify early childhood teacher's self-differentiation and self-efficacy on psychological well-being. The subjects were 293 teachers in 39 early childhood education institutions in K city and J province.The research tools for measurement have been used to self-differentiation (Je Seokbong, 1989) self-efficacy(Park Seonyeong, 2012) and psychological well-being(Ko Kyungae, 2010). The data is analyzed through t test, one-way analysis of variance, correlation, regression analysis. In conclusion, their ages of general background that have a distinction betweeen self-differentiation and self- efficacy as well as psychological well-being, these two self-defferenciation and self- efficacy have a correlation and for being affected by psychological well-being as a fluctuation. That is, teachers who have psychological struggle and anxiety are insufficient to teach young children warmly and comfortably, therefore, they should accept self and young children positively, maintain warm relationship, and develop their own ability or talent, and achieve self matureness as professionals.

The $Fe_{87}Zr_{7}B_{6}$ amorphous alloy after neutron irradiation are studied hysteresis loop and complex permeability measurements. The total integration fluence of fast neutrons is varied from $1.92{\times}10^{14}$ to $4.85{\times}10^{16}n_{f1}cm^{-2}$. After neutron irradiation, the imaginary part of complex permeability in low frequency region decreased due to the decrease of wall motion, but the permeability in high frequency region increased due to the enhancement of rotational magnetization. The measurement of hysteresis loop showed the increase of magnetic softness, related to rotational magnetization, but saturation magnetization was decreased in neutron irradiation sample.

This study examined the mediating effects of self-reassuring and self-attacking in the relationship between mental health and psychological well-being among college students. The study subjects were 230 (98 males and 132 females), and the collected data were analyzed using the SPSS PROCESS Macro based on regression analysis. The results of the study were as follows. First, there were significant relationship among mental health, psychological well-being, self-reassuring and self-attacking. Second, depression, obsessive compulsive disorder, interpersonal sensitivity and psychosis had a significant negative effect on psychological well-being. Third, self-reassuring and self-attacking had a partial mediating effect on the relationship between mental health and psychological well-being. The indirect effect of mental health on psychological well-being through self-reassuring was significantly higher than the indirect effect of psychological well-being through self-attacking. Based on the results of this study, we discussed the role of self-reassuring in the relationship between mental health and psychological well-being.

Induced anisotropy with the energy of $6{\times}10^4\; J/m^3$ is obtained in amorphous Sm-Fe based thin films which are fabricated by rf magnetron sputtering under a magnetic field of 500~600 Oe. Compared with conventional thin films, the anisotropic thin films exhibit a similar "saturation" magnetostriction, but show a very large anisotropy in magnetorstiction which is of significant practical importance due to increased strain at a particular direction. It is shown from a systematic investigation over a wide composition range for binary Sm-Fe alloys that anisotropy is also induced, though small, during a normal sputtering procedure due to the stray field, and the largest anisotropy is observed in the composition range of 25~30 at.% Sm. Furthermore, induced anisotropy is also found to be formed by magnetic annealing, but the anisotropy energy is much smaller than that by magnetic sputtering. This may be because the volume diffusion by which atoms move during magnetic annealing to from induced anisotropy is much slower than the surface diffusion which is expected to be a dominant factor during magnetic sputtering.puttering.
