Government initiatives are continuously being invested to nurture supporting business environment for small and medium sized enterprises (SMEs), such as government-support ERP systems project for SMEs. As such, scholars need to pay attention to SMEs can successfully adopt and manage government-support ERP systems. This study, therefore, conceptually developed and tested a research model for understanding what factors influence SMEs' intention to adopt government-support ERP systems. We obtained thirty samples from SMEs, which is organizational level, and data were analyzed using the partial least square (PLS) technique. The results of data analysis found that institutional pressure and resource dependence had positive effects on the adoption of government-support ERP systems. On the other hand, risk aversion of SMEs was found to have negative effects to adopt government-support ERP systems.

Optical fiber is indispensable for optical communication systems that transmit large volumes of data at high speed, but super precision technology in sub-micron units is required for optical axis adjustment. We developed the automatic optical fiber by image processing and automatic loading system. we have developed 6-axis micro stage system for I/O optical fiber arrays, the initial automatic aligning system software for a input optical array by the image processing technique, fast I/O-synchronous aligning strategy, the automatic loading/unloading system and the automatic UV bonding mechanism. In order to adjust the alignment it used on PC based motion controller, a $10{\mu}m$ repeat-detailed drawing of automatic loading system is developed by a primary line up for high detailed drawing. Also, at this researches used the image processing system and algorithm instead of the existing a primary hand-line up and fiber input array and waveguide chip formed in line by automatic.

The use of electricity to evoke s skeletal muscle response is FES, which is a form of functional electrical stimulation. In the case of the damaged spinal cord, the technique can supply stimulation to the lower moter neurons and their muscle fiber, which have been disconnected from control of the higher nervous system. Recent advances in electronics, particularly miniaturization, have made possible the design of much improved systems of electrodes and stimulaters for FES. Clinical research has followed two main lines: the use of FES in the upper extremities for producing functional hand rehabilitation in quadriplegics and in the lower extremities for producing standing and gait in paraplegics.

An adaptive beamforming system based on code filtering and differential correlation approaches is proposed. The differential correlation method was originally proposed for time delay estimation of direct sequence code division multiple access (DS-CDMA) systems under near-far ratio conditions and the code filtering correlation algorithm, on the other hand, was proposed for array response estimation in DS-CDMA systems under perfect power control. In this paper, by combining differential correlation concept with the code filtering beamforming technology, an accurate estimate of the beam forming weights and an enhanced performance of DS-CDMA systems under sever near-far ratio conditions is achieved. The system performance in terms of beam pattern and bit-error-rate (HER) shows that the proposed adaptive beamformer outperforms the conventional code filtering correlation technique.

DLC coating on ceramics is very useful for manufacturing the materials with hardness and low friction. Adhesion of DLC thin film on ceramics, on the other hand, is usually very weak. Adhesion of DLC film depends on many parameters such as contamination and chemical bonding between thin film and substrate. In this study, adhesion of DLC film on ceramics was improved by the intermediate layer when the plasma immersion ion deposition (PIID) technique was applied. It is found that the chemical composition and the thickness of intermediate layer have significantly an effect on the adhesion of DLC thin film on $Al_2O_3$.

This study presents the dynamic wetting characteristics of an impact droplet on hole-patterned textured surfaces. The flat surfaces were manufactured by a drilling machine to generate the micro-order holes, leading to make the surface hydrophobic. Other flat surfaces were fabricated by the anodizing technique to make hydrophilic texture surfaces with a nanometer order. For hydrophilic and hydrophobic textured surfaces with similar texture area fractions, the impinging droplet experiments were conducted and compared with flat surface cases. As results, an anodized textured surface decreases apparent equilibrium contact angle and increases contact diameters, because of increase in contact area and surface energy. This is attributed to more penetration inside holes from larger capillary pressure on nanometer-order holes. On the other hand, temporal evolution of the contact diameter is smaller for the hydrophobic textured surface from less penetration on the micro-order holes.

The clients of hotel desire to be recognized as special persons who have their own personality and self-consciousness. The other hand, The hotel concentrates upon marketing strategy which acts a part of expanding sales. Namely, They find out the need of client, satisfy the desired need, ensure and manage the existing regular customers and make new clients regular customers. So they gain an advantage over competitive hotels. They make strategics of Telemarketing technique which is one of the developed-marketing techniques, can provide distinctive and familiar service and have an hight effect at the low cost. The attractions of Telemarketing strategy can be explained as follows. 1. It is the medium that have cost efficiency. 2. It possesses attractions to do time management. 3. It has control cash flow. 4. It can improve cash flow. 5. Market expansion can be accomplished. 6. It is a medium fit for prospecting over long-term period. 7. It can improve customer relations. 8. It fits seasonality (seasonal sales) 9. It brings greater order volume. 10. It benefits from lower personnel costs. 11. High volume productivity is realized. 12. It has attraction of versatility. 13. It has ease of start-up.

A three-dimensional locally one-dimensional multiresolution time-domain(LOD-MRTD) method is introduced and unconditional stability is proved analytically. The updating formulations have fewer terms on the right-hand side than those of an alternating direction implicit MRTD(ADI-MRTD). The validation of the method is presented using the resonance frequency problem of an empty cavity. The reduction of the numerical dispersion technique is also combined with the proposed method. The numerical examples show that the combined method can improve the accuracy significantly.

The idea of King Hungdok's prohibition of clothing was to restrict the use of chinese-made cloth on the one hand and to compell his people to use Korean-made cloth for their apparel on the other. The prohibition of clothing sprang from King Hungdok's aspiration to restore his dynasty that had been falling due to the repeated drought disaster and luxurious living of the aristocracy. Safflower, Rubeaceae roots and Sapan wood are well known as some of the earliest natural red-dyes, exhibiting beautiful red-color in our anciet cultural tradition. The color yellow was considered from ancient time to the Chosun Dynasty as the central color. Thus, this color became the royal color for the costumes in the palace. Those plants used to make the color yellow are: Gardenia, phellodendron amurense, Turmeric, coptis, safflower, Arthraxon hispidus, Styphnolobium japonicum. Shikon, root of violet plant, is well known as one of the earliest natural days. By repeating the difficult process of making various dyes constantly during many centuries, the Korean people developed the marvelous technique of making natural color.

Dynamic behaviors and stability of an optical disk drive coupled with an automatic ball balancer (ABB) are analyzed by a theoretical approach. The feeding system is modeled a rigid body with six degree-of-freedom. Using Lagrange's equation, we derive the nonlinear equations of motion for a non -autonomous system with respect to the rectangular coordinate. To investigate the dynamic stability of the system in the neighborhood of the equilibrium positions, the monodromy matrix technique is applied to the perturbed equations. On the other hand, time responses are computed by the Runge -Kutta method. We also investigate the effects of the damping coefficient and the position of ABB on the dynamic behaviors of the system.
