In the domestic cosmetics market, it is important to secure high customer loyalty in order to stably enter the market. To do this, customers should have a deep sense of trust and bond through the authenticity of the brand. At this time, among the components of brand authenticity, only corporate authenticity has a positive effect on customer brand attachment and loyalty. This paper suggests marketing strategies based on CSR activities that can most effectively show corporate authenticity. First, only cases where the activity was continued for more than one year and the activity contents and results were clear and recognized for authenticity were selected. Twenty cosmetic brands met this condition and 28 CSR activities which conducted by the brand are analyzed. The characteristics of each area were derived by dividing it into four areas of desirable society presented by the EU, and a marketing strategy for each type was presented. This research will be of practical help in conducting CSR activities later in the enterprise.

The movie offers a chance to observe the social signifier and the sensitivity of audiences who feel sympathy with the tragic history of crown prince Sado. While watching the movie, the audience halts between ideas whether to go back to "primary ego", or to play the unconscious hypocrisy or the ingrained social behavior which is to resolve the internal conflicts while they face two contrary opinions; one is the obedient subject to obey fatherness, as a symbol of historic value and convention in a society, and the other is the resistant body to break the bond of convention. The audience may feel some ambivalent feelings of the moral values between the paternal authority and the existential philosophical value of 'self'. This study will observe the audience's response of Sado toward the moral norms of the society when they face the signifier of father in the movie with experience the conflict between their resistant ego and madness. Also the study will discuss that the social landscape such as norms, order, and legal system is ever-changing and open to be subverted by the future even though audience hope that the present moral value with which we are content ever-last.

Friction welding of $Al_2O_3$ particulate reinforced aluminum composites was performed and the following conclusions were drawn from the study of interfacial bonding characteristics and the relationship between experimental parameters of friction welding and interfacial bond strength. Highest bonded joint efficiency (HBJE) approaching $100\%$ was obtained from the post-brake timing, indicating that the bonding strength of the joint is close to that of the base material. For the pre-brake timing, HBJE was $65\%$. Most region of the bonded interface obtained from post-brake timing exhibited similar microstructure with the matrix or with very thin, fine-grained $Al_2O_3$ layer. This was attributed to the fact that the fine-grained $Al_2O_3$ layer forming at the bonding interface was drawn out circumferentially in this process. Joint efficiency of post-brake timing was always higher than that of pre-brake timing regardless of rotation speed employed. In order to guarantee the performance of friction welded joint similar to the efficiency of matrix, it is necessary to push out the fine-grained $Al_2O_3$ layer forming at the bonding interface circumferentially. As a result, microstructure of the bonded joint similar to that of the matrix with very thin, fine-grained $Al_2O_3$ layer can be obtained.

The development of mobile devices and the spread of wireless network help share and exchange information and resources more easily. The bond them to Cloud Computing technology help pay attention to "Mobile Cloud" service, so there have been being a lot of studies on "Mobile Cloud" service. Especially, the important of 'Recommendation Service' which is customized for each user's preference and context has been increasing. In order to provide appropriate recommendation services, it enables to recognize user's current state, analyze the user's profile like user's tendency and preference, and draw the service answering the user's request. Most existing frameworks, however, are not very suitable for mobile devices because they were proposed on the web-based. And other context information except location information among user's context information are not much considered. Therefore, this paper proposed the context-aware framework, which provides more suitable services by using user's context and profile.

The plastic hinge region of RC pier ensures its nonlinear behavior during strong earthquake events. It is assumed that the piers secure sufficient strength and ductility in order to prevent the collapse of the bridge during strong earthquake. However, the presence of a lap-splice of longitudinal bars in the plastic hinge region may lead to the occurrence of early bond failure in the lap-splice zone and result in significant loss of the seismic performance. The current regulations for seismic performance evaluation limit the ultimate strain and displacement ductility considering the eventual presence of lap-splice, but do not consider the lap-splice length. In this study, seismic performance test and analysis are performed according to the cross-sectional size and the lap-splice length in the case of longitudinal bars with lap-splice located in the plastic hinge region of existing RC bridge columns with circular cross-section. The seismic behavioral characteristics of the piers are also analyzed. Based upon the results, this paper presents a more reasonable seismic performance evaluation method considering the lap-splice length and the cross-sectional size of the column.

Ab initio SCF calculations have been carried out for the five conceivable trimers formed between one hydrogen cyanide and two hydrogen fluorides using a basis set of TZ＋P quality. Several ground state properties of these trimeric complexes have been evaluated, and compared with those of isolated monomers and appropriate dimers. Computed equilibrium geometries, stabilization energies, and dipole moments are given in order to suppliment the available experimental data. At this level of approximation, intramolecular bond distances are consistently shorter than experimental ones. However, intermolecular distances upon complex formation, and dipole moments are overestimated compared with experimental ones. HCN$(HF)_2$ trimer appears to be the most favourable among the five kinds of trimer complex, and also more stable than $(HCN)_2HF$. The typical features of the non-additivity of intermolecular interaction are relatively strong in the HCN$(HF)_2$ trimer.

Ultra Super Early Strength Cement is a material that satisfies these requirements. early hydration heat however, is significant over regular concrete, thus discretion is advised for thermal cracks in accordance with heat generation when constructing a large-scale structures. In addition, the negative point that it is difficult to achieve required strength in a short period of time following rubbing process while retaining workability, the cement is being used conditionally for engineering material and Ultra Super Early Strength Cement for maintenance material for construction doesn't exist. Magnesia Phosphate Cement, which is currently under studies in overseas uses no extra admixture and has strong points of Ultra Super Early Strength as well as favorable construction-ability and adhesive stability to the prototype concrete. These factors stem recognition that it could be used as maintenance material for construction of diverse applicability. In order to provide necessary data to increase practicality of the magnesia phosphate cement for Ultra Super Early Strength Mortar, the study carried out simulate experiment on member of framework to review field applicability.

Fiber is an important ingredient in strain-hardening cementitious composite (SHCC), which can control fracture of cementitious composite by bridging action. The properties of reinforcing fiber, as tensile strength, aspect ratio and elastic modulus, have great effect on the fracture behavior of SHCC. But SHCC has serious problem as drying shrinkage because silica powder is used to make SHCC in order to improve bond strength between reinforcing fibers and cement matrix. Therefore, curing method (period and temperature) is very important for SHCC to show high tensile performance. a variety of experiments have being performed to access the performance of SHCC recently. This research emphasis is on the mechanical properties of SHCC made in Polyvinyl alcohol (PVA), Polyethylene (PE) fibers and steel cord (SC), and how curing method affects the composite property, and ultimately its strain-hardening performance.

Recently phage K11 lysozyme was cloned and characterized in our lab. The K11 lysozyme was identified to have dual functions. It not only cuts a peptidoglycan bond in bacterial cell wall but also acts as an inhibitor of K11 RNA polymerase. It has been known that the T7 lysozyme binds specifically to T7 RNA polymerase and inhibits transcription. The dual activities of K11 lysozyme are atreeable to the case of T7 phage lysozyme and RNA polymerare. In order to identify the binding magnitude of K11 lysozyme with K11 RNA polymerase, yeast two-hybrid system was used. K11 phage lysozyme gene was introduced into pLexA plasmid and used as a prey. Also, K11 phage RNA polymerase gene was introduced into pJG4-5 and used as a bait. The binding between K11 lysozyme and K11 RNA polymerase was demonstrated by expression of reporter genes such as lacZ and leu2.
