  • In spite of all fine methods developed for treating cleft lip, a certain percentage of cases might still need secondary correction. Generally, secondary revision of cleft lip is much difficult to produce esthetic outcome, because the cleft lip scar gives a variable symmetrical and anatomic defect that may not be possible to make inconspicuous of this scar and rebuild good esthetics. In this case report, a five year-old girl was underwent secondary cleft lip repair using straight line technique to correct unfavorable postoperative scar, peaking of Cupid's bow, notching of vermillion and shortened lip on cleft side with simultaneous repairing cleft palatal fistula. After operation, the secondary deformity was much improved, but, long term follow up is needed to evaluate the additional postoperative deformity might be happen during growth.

  • MicroLEDs have various advantages and application areas and are in the spotlight as next-generation displays. Nevertheless, the commercialization of microLEDs is slow because of high cost as well as difficulties in the transfer, bonding, and bad pixel repairing process. In this study, we review the development trends of transfer, bonding, and defective pixel repair technologies, which are critical for microLED commercialization, focusing on materials that determine these technologies. In addition, we focus on the simultaneous transfer bonding technology developed by the Electronics and Telecommunications Research Institute, which has been attracting enormous research attention recently.

  • Cloud computing has recently become an attractive solution for massively multiplayer online games(MMOGs), as it lifts operators from the burden of buying and maintaining hardware. Peer-to-peer(P2P) -based solutions present several advantages, including the inherent scalability, self-repairing, and natural load distribution capabilities. We propose a hybrid architecture for MMOGs that combines technological advantages of two different paradigms, P2P and cloud computing. An efficient and effective provisioning of resources and mapping of load are mandatory to realize an architecture that scales in economical cost and quality of service to large communities of users. As the number of simultaneous players keeps growing, the hybrid architecture relieves a lot of computational power and network traffic, the load on the servers in the cloud by exploiting the capacity of the peers. For MMOGs, besides server time, bandwidth costs represent a major expense when renting on-demand resources. Simulation results show that by controlling the amount of cloud and user-provided resource, the proposed hybrid architecture can reduce the bandwidth at the server while utilizing enough bandwidth of players.

  • Purpose : To evaluate the results and usefulness of meniscal repair using meniscal arrows with ACL reconstruction. Material and Methods : Among cases of the simultaneous meniscal arrow fixation and ACL recontruction performed between May, 1997 and September, 2000, 17 cases could be evaluated. The average follow-up were 18.5 months. Twelve cases were medial meniscus, 5 cases, lateral meniscus. All cases were longitudinal tear. Meniscal tear were seen at red-red zone in 13 cases, red-white zone in 5 cases. The results were analyzed by pain, joint line tenderness, locking, McMurray test, the Marshall knee scoring scale and complications. Results : Postoperatively two patients had mild joint line tenderness without pain on joint motion or weight bearing. No patient had locking or positive McMurray test. At last follow-up, 15 cases $(88\%)$ were 'excellent' or 'good' according to the Marshall knee score scale. There were two complications which are soft tissue irritation sign on active knee motion and a femoral chondral injury due to protruded T-shaped head of meniscus arrow. Conclusion : Meniscus arrow can be one of the options in repairing the associated meniscus tear, especially the posterior horn of medial meniscus, during ACL reconstruction. However, surgeons using meniscus arrow should be aware of its potential complications such as pain due to soft tissue irritation and chondral damage of the femoral condyle.
