An optimization formulation of unconstrained damping treatment on beams is proposed to minimize vibration responses using a numerical search method. The fractional derivative model is combined with RUK's equivalent stiffness approach in order to represent nonlinearity of complex modulus of damping materials with frequency and temperature. The loss factors of partially covered unconstrained beam are calculated by the modal strain energy method. Vibration responses are calculated by using the modal superposition method, and of which design sensitivity formula with respect to damping layout is derived analytically. Plugging the sensitivity formula into optimization software, we can determine optimally damping treatment region that gives minimum forced response under a given boundary condition. A numerical example shows that the proposed method is very effective in minimizing vibration responses with unconstrained damping layer treatment.

Current treatment for adolescent idiopathic scoliosis(AIS) consists of three phases: observation, bracing, and surgery. Although there are many nonsurgical treatment(bracing, electrical stimulation, exercise, manipulation, acupuncture, etc), their effect is still controversial. In many paper, Schroth method was reported good immediate response to conservative care, which could be considered a sign of good prognosis. Schroth method became effective thai specialists in physiotherapy for spinal deformities teach the patient how to perform a routine of 'curve pattern' specific exercises with the purpose to facilitate the correction of the asymmetric posture and to teach the patient to maintain the corrected posture in dally activities. This Principles of correction exercise treatment are based on those developed by the German physiotherepist K. Schroth.

Arc metal spraying is a widely used method for improving the performance of construction structures such as corrosion resistance and electromagnetic wave shielding. However, when arc metal spraying is applied to a concrete structure, adhesion performance may deteriorate. Therefore, the effect of each surface treatment method on the physical properties between the arc metal spray coating and concrete was reviewed by evaluating the deposition efficiency and adhesion performance according to the arc metal spray surface treatment method (surface reinforcing agent, roughening agent, and sealing agent). As a result, it is suggested as an optimal surface treatment condition to induce non-interface failure by using a roughening agent and to improve the properties of concrete and metal coatings by applying a surface reinforcing agent and sealing agent.

Carbon nanotube cathodes (CNT cathodes) were fabricated by a screen printing method using multi-walled carbon nanotubes. The effects of surface treatment on CNT cathodes were investigated for use in high efficiency field emission displays. The optimum surface treatment for a CNT cathode is dependent on a relative bonding force of CNT films on the cathode after a heat treatment. Because of the high bonding force used in the Liquid method, this method is recommended for CNT cathodes which are heat-treated at $390^{\circ}C$ in a $N_2$ atmosphere. The Rolling method is applicable for CNT cathodes fabricated at $350^{\circ}C$ in an atmosphere of air. The results of this study provide basic criteria for the selection of an appropriate surface treatment for large area CNT cathodes.

Objectives : The aim of this paper is to compare the mechanisms of the OP/LB method and the SSD treatment in 『Piweilun』. Methods : Wenbing texts, articles on the OP/LB method, and the 『Piweilun』 was examined for comparison of treatment mechanisms of SSD. Results : The mechanism of the OP/LB method in treating SSD was to treat the Spleen and Stomach separately, to restore the ascending/descending pattern of qi through simultaneous use of pungent and bitter flavors which raises and lowers, respectively. Moreover, the use of medicinals with contrary properties regulate the other's biased nature, and none of the medicinals create dampness. The pungent and bitter flavors play central roles, where the pungent flavor opens and communicates and the bitter flavor clears and lowers. The treatment method of SSD in the 『Piweilun』 treat the Spleen and Stomach together, with a focus on raising and dispersing through upraising yang and reinforcing qi by means of Wind medicinals with pungent and bitter flavors added to sweet and warm medicinals. Conclusions : Owing to the expansion of the OP/LB method concept by modern-contemporary scholars, the potential for treating SSD as can be seen in the 『Piweilun』 with the OP/LB method has emerged. The similarity between the OP/LB method and treatment of SSD in the 『Piweilun』 is that the objective of the formulas is to lower fire heat and communicate qi to help qi movement. This common objective allows for treatment of SSD within Wenbing and those in 『Piweilun』 with the said formulas through appropriate modification fit for each situation.

This study was carried out to know bending process property of bentwood by treatment methods such as microwave and ammonia solution treatment. Bentwood processing was operated on bending-jig form with 60mm and 100mm radius of curvature (ROC). The species was used to Korean red pine (Pinus densiflora). No significant difference was shown in bentwood processing method on ROC. In treatment method, ammonia solution treatment for bentwood was better in dimensional stability and working ability than that of microwave treatment. However, bentwood stress was reduced with ammonia solution treatment. Color of bentwood surface appearance has a dark tendency in ammonia solution treatment. But it seems to beautiful effect of apparent annual ring is rising esthetically by ammonia solution treatment. To utilize wood as a exterior material for living amenity, it has to be closely examined from various angles including surface property, degree of swelling and shrinkage, drying state, retaining strength, durability, safety, and insect damage.

Laser surface hardening process is the method of hardening surface by inducing rapid self quenching of laser injected area through transfer of surface heat to inside after rapid heating of laser injected area only by high density energy heat source. This surface treatment method does not involve virtually any thermal deformation by heat treatment nor accompanies any other process after surface hardening treatment. In addition, allowing local machining, this method is a surface treatment method suitable for die with complicated shape. In this study, die material cast iron was surface-treated by using high power diode laser with beam profile suitable for heat treatment. Since the shapes of die differ by press die process, specimens were heat-treated separately on plane and corner depending on the applied parts. At this time, corner heat treatment was done with optic head inclined at $10^{\circ}$. As a result, corner heat treatment easily involves concentration of heat input due to limitation of heat transfer route by the shapes compared with plane part, so the treatment accomplished hardening at faster conveying speed than plane heat treatment.
