The purpose of this study is to explain experiences of non-music majors to changing their majors into music therapy and to provide the preliminary study for deriving a grounded theory. For that, in-depth interviews were performed targeting 5 students who did not major in music in their undergraduate courses selected from the graduate students who are majoring in music therapy at the colleges located in Seoul. Data was analyzed for the study by applying the modified grounded theory. The result of study showed that they selected the course of music therapy career as they were motivated by the realistic demand for future employment, career potentials and other realistic causes. These factors caused them to study the surrounding situations and conduct the detailed research on the possibility of music therapy. These factors were also dependent on the individual characteristics, external elements and music background. These experiences were connected to the self-integration and pursuit of growth by newly setting their relation to the 'Music Child'. In addition, the demand of being the meaningful existence in relationship also affected them to more specify their aspirations in the progress of career selection on a continual basis. This study is meaningful as it provides the actual information on them.

The host rock of standing sculptured Buddha in the Yongamsa temple was macular biotite granite, which has gone through mechanical and chemical weathering. The principal rock-forming minerals are quartz, plagioclase, alkali feldspar, and biotite, the last two of which have been transformed into clay minerals and chlorite due to weathering processes. The bed rock around the Buddha statue is busily scattered with steep inclinations that are almost vertical and discontinuous planes with the strikes of $N8^{\circ}E$. The major joints have the strikes of N4 to $52^{\circ}W$ and N6 to $88^{\circ}E$ and the dips of 42 to $89^{\circ}$. Especially thee development of the joints that cross the major joints causes tile structural instability of the rock. The host rock of the Buddha image is separated into many different rock masses because of the also many different discontinuity, which group accounts for about $12{\%}$ of the rock. Thus it's estimated that the bed rock has not only plane and toppling failure but also wedge failure in all the sides. Since the earth pressure and the inclination pressure are imposed on the body of the Buddha in the basement rock, it's urgent to give a treatment of geotechnical engineering for the sake of its structural stability. The parts where serious fractures are seen should receive the hardening process using the fillers for stones. It's also necessary to introduce a landfill liner system in order to reduce the ground humidity. The rock surface of the Buddha statue are partly contaminated by lichens and bryophyte. The joints have turned into earth, which promotes the growth of weeds and plant roots. Thus biochemical treatments should also be considered to get rid of the vegetation along the discontinuous planes and prevent further biological damages.

The electrolytic reduction of a spent oxide fuel involves a liberation of the oxygen in a molten LiCl electrolyte, which results in a chemically aggressive environment that is too corrosive for typical structural materials. Accordingly, it is essential to choose the optimum material for the processing equipment that handles the high molten salt. In this study, hot corrosion studies were performed on bare as well as coated superalloy specimens after exposure to lithium molten salt at $675^{\circ}C$ for 216 h under an oxidizing atmosphere. The IN713LC superalloy specimens were sprayed with an aluminized NiCrAlY bond coat and then with an $Y_2O_3$ top coat. The bare superalloy reveals an obvious weight loss due to spalling of the scale by the rapid scale growth and thermal stress. The chemical and thermal stability of the top coat has been found to be beneficial for increasing to the corrosion resistance of the structural materials for handling high temperature lithium molten salts.

Glass formation, thermal property and crystallization behavior were investigated in $xK_2O-(33.3-x)BaO-16.7TiO_2-50SiO_2(mole\%)$ with fresnoite($Ba_2TiSi_2O_8$) crystal by replacement BaO for $K_2O$. As x(0$\le$x$\le$20) contents increased, glass formation became easy, and crystallization temperature moved on to the low temperature. Crystal phase of the $Ba_2TiSi_2O_8$ was confirmed by XRD, and the replaced x was not effected on the formation of new crystals. The kinetics of crystallization of fresnoite were studied by applying the DTA measurements carried out at different heating rates. The average avrami exponent(n) and activation energy were changed $2.26 {\pm}0.1,\;2.03 {\pm}0.1,\;1.93{\pm}0.15$, $279 {\pm}12kJ/mole,\;302{\pm}7kJ/ mole,\;319{\pm}1kJ/mole$ according to x contents, respectively. The replaced x improved the orientation of crystal growth.

With a growing concern about climate change and green house gases mitigation, carbon labeling policy has been launched in several countries as an environmental policy which connects low carbon production to low carbon consumption. This research aims to propose a model that explains consumers' attitude and brand loyalty toward carbon labeling products. This model specifies the consumer's psychological processes by which consumer values, such as autonomy and environmental values, affect carbon labeling product and corporate images and finally form brand loyalty toward carbon labeling products. Panel data were collected in two separate surveys and analyzed using a structural equation technique. Results are summarized as follows. First, consumers' autonomy value(AV) positively affects locus of control(LC) and corporate image(CI). Second, consumers' environmental value(EV) positively influences perceived consumer effectiveness(PCE), which in turn has a negative effect on perceived barriers(PB). Perceived barriers finally affect product image(PI) negatively. Third, both corporate image and product image have causal relationships with brand loyalty. Our results suggest that carbon labeling policy contributes not only to the reduction of greenhouse gases but also to the increase of consumers' attitude and brand loyalty toward carbon labeling products. This research also provides governments with directions for efficient environmental policy and firms with guidance on effective marketing strategies about carbon labeling.

This study aims to explore the effects of the parenting education program for high-school maladjusted students. To this purpose, a parenting education program for adolescents developed by the Ministry of Gender Equality and Family(MOGEF) was applied to ten high-school maladjusted students in an alternative(Dae-an) class in Jeju. Findings from class observations and interviews with participants are as follows. First, students with school maladjustment recognized importance and necessity of positive self-concepts and had an opportunity for self-growth through parenting education program. Second, students with school maladjustment obtained understanding about their family of origin and confidence for forming their future families. Third, advance learning about meanings and roles of being a parent provided students with opportunities to know importance of responsible sexual behavior. Fourth, practices of basic care with a replica of a new-born baby enhanced participation and concentration level of students with school maladjustment which became extremely effective in obtaining necessary knowledge for the basic care. Fifth, information provision for parent roles according to children's different developmental levels let students recognize that parent's roles change as their children grow and opened a way to grasp the need of parent education. Sixth, education and repetitive practices on reflective listening helped students enhance communication skills which entailed expanding their human relations. Seventh, passing-down of emotion and understanding on child abuse allowed students recognize risks of child abuse as well as the importance and need of skills for controlling emotion. This study sheds lights on the feasibility and effectiveness of a parenting education program for maladjusted or vulnerable students as an effective program for school drop-out prevention.

Structural and thermo-analytical studies were carried out to understand the phase formation kinetics of the single phase $Bi_5Ti_3FeO_{15}$ (BTFO) nanocrystals in $Bi_2O_3-Fe_2O_3-TiO_2$, during the polymerized complex (PC) synthesis method. The crystallization of Aurivillius phase $Bi_5Ti_3FeO_{15}$ layered perovskite was found to be initiated and achieved under the temperature conditions in the range of ${\sim}$800 to 1050$^{\circ}C$. The activation energy for grain growth of $Bi_5Ti_3FeO_{15}$ nanocrystals (NCs) was very low in case of NCs formed by PC (2.61 kJ/mol) than that formed by the solid state reaction (SSR) method (10.9 kJ/mol). The energy involved in the phase transformation of Aurivillius phase $Bi_5Ti_3FeO_{15}$ from $Bi_2O_3-Fe_2O_3-TiO_2$ system was ${\sim}$ 69.8 kJ/mol. The formation kinetics study of $Bi_5Ti_3FeO_{15}$ synthesized by SSR and PC methods would not only render a large impact in the nanocrystalline material development but also in achieving highly efficient visible photocatalysts.

The fusion of nano technology and information technology is essential to sustain the present growth rate and to induce new industry in this ever-growing information age. Considering Korean industry whose competitiveness lies heavily on information related technologies, this field will be inevitable for future. Nano materials can be described as novel materials whose size of elemental structure has been engineered at the nanometer scale. Materials in the nanometer size range exhibit fundamentally new behavior, as their size falls below the critical length scale associated with any given property. " Bottom-up' techniques involve manipulating individual atoms and molecules. Bottom-up process usually implies controlled or directed self assembly of atoms and molecules into nano structures. It resembles more closely the processes of biology and chemistry, where atoms and molecules come together to create structures such as crystals or living cells. Nano scale sensors are included in the electronics area since the diverse sensing mechanisms are often housed on a semiconductor substrate and usually give rise to an electronic signal. The application of nano technology to the chemical sensors should allow improvements in functionality such as gas sensing. In this presentation, we will discuss about the nano scale information materials and devices fabricated by using the organic/inorganic nano templates.

Corneal endothelium is mono-inner cell layer of cornea and lay on Descmet's membrane which comprised of various proteins called extracellular matrix such as fibronectin, collagen, laminin, and proteoglycan, etc. In this study, we fabricated transparent poly(lactic-co-glycolic acid) (PLGA) film because PLGA is widely used for tissue engineering based on their properties. We investigated the behaviors of rabbit corneal endothelial cells (rCEnCs) on PLGA film surfaces coated with various cell-adhesive molecules like fibronectin, laminin, collagen type I and IV and FNC coating mix. The morphologic images, proliferation and adhesion assay, immunofluorescence for ZO-1 and $Na^+/K^+-ATPase$ and RT-PCR for expression of specific markers were conducted. These results showed that PLGA film plays a role as CEnC carriers in vitro and the cell-adhesive molecules give positive effects on the behaviors of rCEnC.
