In this study, a novel strategy was developed for the highly selective immobilization of proteins, using the polyhydroxyalkanoate (PHA) depolymerase substrate binding domain (SBD) as an active binding domain. In order to determine the appropriacy of this method for immunodiagnostic assays, the single-chain antibody (ScFv) against the hepatitis B virus (HBV) preS2 surface protein and the severe acute respiratory syndrome coronavirus (SARS-CoV) envelope protein (SCVe) were fused to the SBD, then directly immobilized on PHA-coated slides via microspotting. The fluorescence-labeled HBV antigen and the antibody against SCVe were then utilized to examine specific interactions on the PHA-coated surfaces. Fluorescence signals were detected only at the spotted positions, thereby indicating a high degree of affinity and selectivity for their corresponding antigens/antibodies. Furthermore, we detected small amounts of ScFv-SBD (2.7 ng/mL) and SCVe-SBD fusion proteins (0.6 ng/mL). Therefore, this mi-croarray platform technology, using PHA and SBD, appears generally appropriate for immunodiagnosis, with no special requirements with regard to synthetic or chemical modification of the biomolecules or the solid surface.

임플란트의 도입으로 악골이 흡수된 무치악 환자의 보철 치료에 획기적인 변화가 가능해졌다. 특히 하악 무치악 환자의 경우 2개의 임플란트에 의해 유지를 얻는 피개의치가 일반적인 총의치의 대안으로 자리잡았으며 첫 번째로 고려되어야 할 치료 방법으로 받아들여지고 있다. 본 증례는 상하악 완전 무치악 환자로서 상악에는 일반적인 총의치, 하악에는 2개의 임플란트를 식립하고 $Locator^{(R)}$ Attachment를 사용하여 수복한 임상과정 및 결과에 관하여 보고하고자 한다. It is difficult to provide prosthodontic treatment to fully edentulous patients with severe alveolar bone resorption, because this makes patents hard to endure functional load, and to adapt to the dentures, which result in emotional stress to patients. Implant supported overdenture can be chosen to solve these problems. Among several types of them, the implant retained and tissue supported overdenture, is available to the patients of low masticatory force with the reduced cost. Attachments also can be used for increasing retention and esthetics in dentures. Especially, $Locator^{(R)}$ system needs a small vertical interarch space for restoration and is able to compensate the difference of angle between fixtures. In this study, we restored maxilla with conventional complete denture, and mandible with implant and tissue supported overdenture and $Locator^{(R)}$ system.

Cognitive radio is a paradigm for wireless communication in which either network of wireless node itself changes particular transmission or reception parameters to execute its tasks efficiently without interfering with the licensed users. This paper represents a performance of the cognitive radio technology on dual polarized MIMO system using six-port receiver. Six-port technology is well known direct conversion receiver. In this paper, a six-port phase discriminator based polarization signal separation is shown. That is, the SER(Symbol Error Rate) performance is improved using polarization separator and simple receiver architecture is proposed applying six-port receiver. The six-port technology has priority to adapt changeable frequency system and variable environments for cognitive radio. In general, dual polarized MIMO system has good capacity and quality using polarization separator [1].

Purpose: For the correction of ptosis in monocular elevation deficiency (MED) patients, levator resection or frontalis sling operation with various materials has been used. The authors present a case of a monocular elevation deficiency patient who was treated for ptosis using the levator muscle as a frontalis sling. Case summary: A six-year-old male patient with left monocular elevation deficiency underwent a frontalis sling operation using a levator muscle. The patient had received left inferior rectus recession, left medial rectus resection and left lateral rectus recession with transposition. An upper eyelid skin crease incision was made, and the anterior surface of the levator muscle was exposed as far as the Whitnall ligament. A levator muscle flap was then formed from aponeurosis by incising the full width of the levator horizontally, just below the Whitnall ligament and anchored to the frontalis muscle. The surgical result was satisfactory as the preoperative MRD1 was 0.5 mm and the postoperative MRD1 was 2.5 mm. There were no complications such as keratitis or wound problems. Conclusions: The levator muscle flap can be an effective frontalis suspension material to correct ptosis in an MED patient with poor levator function. J Korean Ophthalmol Soc 2010;51(2):282-285
