차세대 네트워크 환경은 유선과 무선, 방송과 통신, 음성과 데이터의 융합을 고려한 통합망 형태로 진화하고 있다. 특히, 인터넷 프로토콜(IP) 기반의 코어 네트워크(Core network)를 중심으로 다양한 접속기술을 갖는 서로 다른 이기종(Heterogeneous) 접속망이 존재하는 환경에서 대용량의 멀티미디어 서비스들을 언제, 어디서나, 이동 중에도 끊김 없이 제공받고자 하는 사용자의 요구 또한 증가하고 있는 상황이다. 본 논문에서는 이러한 융합 서비스 관리자로서 유비쿼터스 식별자(UID)를 사용하여 통합된 식별체계와 인증 및 과금을 지원하고 통합 프로파일 관리를 통하여 사용자 정보를 서비스 제공자에게 제공하는 알고리즘을 구현 단말이 이동되는 경우에도 융합 서비스를 제공할 수 있도록 제시한다.

Physical therapy for patients with Multiple sclerosis, Parkinson's disease, Spinal cord injury. Osteoporosis, CVA and Cerebral Palsy often includes the evaluating and teaching of rolling movements. Motor abilities such as rolling from a supine to a prone position, moving to sitting. getting up on all fours and ultimately standing up from a supine position. represents progression toward physical independence. Rolling is important functional abilities for need to dressing, decubit prevent. bed mobility, neck control, crawling, creeping, sitting, standing and walking. The purposes of this study were to describe motor development concept and rolling task patterns and to approach the therapeutic exercises.

The goal of total disc replacement is to restore pain-free mobility to a diseased functional spinal unit, by replacing the degenerated disc with a mobile bearing prosthesis. SB Charite III is named commercial product as the Artificial Intervertebral Disc (AID). SB Charite III consists of sliding core and endplate made by Ultra-high Molecular Weight Polyethylene (UHMWPE) and cobalt chrome alloy, respectively. To evaluate the effect of von-Mises stress in AID, and three-dimensional finite element model of AID analysis was preformed for four different loading types of sliding core. Consequently, endplate was compared with a compressive preload at 400N and flexion moment at $3{\sim}9Nm4. Therefore, this research has obtained result that von-Mises stress of sliding core in AID disc by radius curvature.

Generalized aggressive periodontitis cause intrabony pocket, loss of teeth, and severe alveolar bone defect. As a result, pathologic tooth migration occurs and esthetic problem happens according to this, especially on the anterior teeth of maxilla. The purpose of this study was to assess the multidisciplinary treatment including periodontics, orthodontics and prosthetics of a patient caused by generalized aggressive periodontitis. This study presents a case using full mouth periodontal treatment, immediate orthodontic treatment for 5 months, implantation with guided bone regeneration and free gingival graft, and prosthetic treatment. Treatments took totally 14 months. Periodontal indicators such as probing pocket depth, bleeding on probing, tooth mobility improved. Also, the patient was satisfied with the esthetic and functional improvement.

The buffer layer was spin-coated on the dielectric layer of OTFTs to introduce the hydrophobicity for enhancing the device performance. this functional layer contains the water-proof ingredient to reduce the surface energy and more importantly, does not harm the dielectric property of the dielectric layer. With the help of proposed hydrophobic layer, the transistor showed dramatic improvement at electrical performance which was almost 20 times higher mobility compared to the non-treated case. And on/off ratio was also guaranteed as $10^{5{\sim}6}$.

The conformational preference of tetrahomodioxacalix[4]arenes with three different para substituents on the phenolic ring has been investigated by using ab initio molecular orbital theory (RHF/6-31$G^{\ast}$) and density functional theory (B3LYP/6-31$G^{\ast}$). The stability order is predicted to be cone > C-1,2-alternate > partial cone > 1,3-alternate > COC-1,2-alternate. The distorted cone conformation is found to be most stable in a gas phase and the calculated results are in agreement with the reported $^1$H NMR and X-ray experimental observations. The substitution of methylene with dimethyleneoxa bridges increases the size of the annulus of the molecule, its conformational mobility, and the number of hydrogen bonding patterns. The thermodynamic stability and the conformational characteristics of tetrahomodioxacalix[4]arenes are discussed in regards of the number of phenolic hydrogen bonding patterns and the polarity of a molecule. The substituent effects on the para position of the phenolic ring are also introduced.

To compare the treatment effects of back exercise on functional status, spinal mobility, SLR, pain severity, and treatment results satisfaction, and to determine whether spinal exercises during the low back pain reduces recurrent episodes of back pain. 1. Flexion and extension exercise groups did not differ in any outcome over 4weeks. After 1week, both exercise groups had reduced disability score, a higher proportion returning to work, and fewer subjects with a positive SLR compared with the control group. 2. There was no difference among groups regarding recurrence of low back pain after 6~12 months. 3. There was no difference for any outcomes between the flexion or extension groups. However, either exercise was slightly more effective than no exercise when patients with low back pain were treated.

The Saccharomyces cerevisiae MGMT gene encodes a O6-methylguanine DNA methyltransferase that protects cells from mutation or death by DNA alkylating agents. Using an in vitro transcription system, we analyzed its promoter region to find regulatory elements for transcription initiation. DNase I footprinting and a transcription assay showed that a functional TATA box, 5'-TGATATAGCA-3', is located in the region spanning from -25 to -34. We also found one upstream repressing sequence (URS), -333 to -213, by promoter deletion and competition analysis. Gel mobility shift assays and Southwestern blot analysis using URS region indicate specific complex formations. These results indicate that several cis-acting and trans-acting elements might be involved in the transcriptional regulation of the S. cerevisiae MGMT gene.

SLS crystallization and CMOS LTPS process have been developed for high performance and uniform characteristics. By strictly optimizing SLS optics in conventional 2 shot SLS process, threshold voltage variation of 720 pixel TFTs in 2.2-inch QVGA panel (240xRGB) was remarkably decreased from 1.89 V to 0.56 V of 3sigma value. Mobility of the channel doped NTFT and PTFT for circuits were $146\;and\;38cm^{2}/Vs$, respectively. Functional unit circuits for SOG were also fabricated and properly operated.
