Linear response from the mixed reference, which combines MS = +1 and -1 components of triplet state, generates additional configurations in the realm of TDDFT. Resultantly, MRSF-TDDFT eliminates the erroneous spin-contamination of the SF-TDDFT. Analytic energy gradients of the response states with respect to nuclear coordinates are also derived and implemented. The computational overhead of singlet or triplet states for MRSF-TDDFT is nearly identical to that of SF-TDDFT. The resulting MRSF-TDDFT computational scheme has several advantages before the conventional SF-TDDFT. Linear-response equations for the singlet and triplet responses are clearly separated. This considerably simplifies the identification of the excited states, especially in the ``black-box'' type applications, such as the automatic geometry optimization, reaction path following, or molecular dynamics simulations of the targeted states. Accuracy of MRSF-TDDFT has been tested and verified in various ways including vertical-excitation energy, singlet-triplet energy gap, adiabatic-excitation energy, optimized structure, minimum energy conical intersection, nonadiabatic coupling term, and nonadiabatic molecular dynamic simulation. Therefore, it is highly expected that the MRSF-TDDFT has advantages over SF-TDDFT in terms of both practicality and accuracy.ABSTRACT CONTENTS LIST OF FIGURES LIST OF TABLES INTRODUCTION 1 THEORETICAL BACKGROUND 6 1.

realized case where self-created value creation of areas through creative integration of artists have occurred. As a result, city governments that advocates a Creative City or Culture City has been executing the establishment of planned creation clusters which intentionally induce the integration of artists in specific areas of the city. On the other hand, Scott (1999) thinks that core assets of creation cluster are the networks of artists and related positive effects. Accordingly, not only various domestic researchers but also establishment subjects of planned creation clusters emphasize the vitalization of networks of living-in artists in creation clusters in common. In spite of these situations, verification of network levels of domestic planned cluster cases which are currently operating domestically is not sufficient, and discussion results about the improvement plans of network levels in creation clusters are insufficient as swell. Reasons of these situations are thought be that approaches to the factors which give influences to network levels in creation clusters were not sufficient. Final purpose of this study is to identify the implications which are referable in the procedures of establishing network levels improvement plans of living-in artists in creation clustersand for this objective, clarification of factors which give influences to network levels in creation clusters and related examination of individual influences is being tried. Among these, the influences of spatial requirements and current utilization conditions of spaces in creation clusters to network levels are studied with priority, which is because creation details of creation clusters have individually different space requirements depending on whether it is self-created or planned. In order to achieve study objective, expected influence factors were prepared which were mentioned earlier to give influences to the network levels in the creation clusters, and Mullae Art Village was selected as a representing case of self-created creation cluster and Sindang Art Arcade was selected as a planned creation cluster. For empirical studies, 30 targeting study subjects of living-in artists in each case were selected and surveys were conducted to measure individual network levels and variables of expected influence factors. Through comparison analysis of measured data, significance of differences in network levels of each case was verified and variables of expected influence factors which showed significant differences were identified. Additionally and in order to verify the correlations between variables of current situation of space utilization and network levels, correlation analysis was conducted, and in order to identify the contexts of correlations, total of 18 living-in artists in each case were selected and examined with interviews. Study results confirmed the significance of the assumption that spatial requirements in relevant cases could give influences to network creation procedures in creation cluster. Living-in artists in Mullae Art Village which have relatively higher network levels live with various common actives in various spaces and transform the new networks in various exchange spaces where the relevant activities are overlapped and the relevant creation cluster is recognized as a concept of town or village. Additionally, close relationships between these spatial requirements and related current conditions of space utilization and physical network creation procedures are identified in correlation analysis and interview results. On the other hand, activities of living-in artists in Sindang Art Arcade show the tendency that their activities are limited to personal activities in their personal spaces and their exchange spaces which could mediate the networks are not sufficient. Accordingly, continuous exchange relationships are identified to be difficult in spite of the conditions that entire living-in artists recognize their existences in living-in artists owing to the public leading network program. Through study results, the necessity is raised for future establishment and operation of creation cluster that network vitalization plans should be added in consideration factors for space plans. In details, the suggestion that establishment of space requirements that enable various everyday activities smoothly and connections with neighboring areas and the implication that establishment of open exchange spaces which enable to overlap various everyday activities should be added in the plans. Current space plans in the procedures of establishment of creation cluster are limited to the standards of construction of facilities to accommodate creation activities. If the derived implication could be developed to detailed space plan methodologies through future in-depth qualitative studies, current concept of planned creation cluster which stays just in the level of facilities is expected to be expanded to the concept of Creative Milieu where self-created interactions between internal members and connections with regional community are required.โ…ฐ. ์„œ๋ก  14 1.1 ์—ฐ๊ตฌ์˜ ๋ฐฐ๊ฒฝ ๋ฐ ๋ชฉ์  14 1.2 ์—ฐ๊ตฌ์˜ ๋ฒ”์œ„ 16 1.3 ์—ฐ๊ตฌ์˜ ํ๋ฆ„ ๋ฐ ๋ฐฉ๋ฒ” 18 โ…ฑ. ์ด๋ก ์  ๊ณ ์ฐฐ 19 2.1 ์ฐฝ์กฐ๋„์‹œ๋ก ๊ณผ ์ฐฝ์ž‘ํด๋Ÿฌ์Šคํ„ฐ 19 2.2 ์ฐฝ์ž‘ํด๋Ÿฌ์Šคํ„ฐ ๋‚ด ๋„คํŠธ์›Œํฌ ๊ด€๋ จ ๋…ผ์˜ 26 โ…ฒ. ๋ฌธ๋ž˜์ฐฝ์ž‘์ดŒ๊ณผ ์‹ ๋‹น์ฐฝ์ž‘์•„์ผ€์ด๋“œ์˜ ๋น„๊ต์‚ฌ๋ก€์—ฐ๊ตฌ 32 3.1 ์‚ฌ๋ก€์—ฐ๊ตฌ์˜ ํ‹€ 32 3.2 ์‚ฌ๋ก€ ๋Œ€์ƒ์ง€์˜ ์ผ๋ฐ˜ํ˜„ํ™ฉ 35 3.3 ์‚ฌ๋ก€ ๋Œ€์ƒ์ง€์˜ ๋„คํŠธ์›Œํฌ ํ™œ๋™ํ˜„ํ™ฉ 41 3.4 ์†Œ๊ฒฐ 47 โ…ณ. ์ฐฝ์ž‘ํด๋Ÿฌ์Šคํ„ฐ์˜ ๊ณต๊ฐ„์  ์กฐ๊ฑด์ด ๋„คํŠธ์›Œํฌ ์ˆ˜์ค€์— ๋ฏธ์น˜๋Š” ์˜ํ–ฅ ์‹ค์ฆ๋ถ„์„ 49 4.1 ๋ถ„์„์˜ ํ‹€ 49 4.2 ์‚ฌ๋ก€์ง‘๋‹จ๋ณ„ ์„ค๋ฌธ์‘๋‹ต๊ฒฐ๊ณผ ๋น„๊ต 53 4.3 ๋„คํŠธ์›Œํฌ ์ˆ˜์ค€๊ณผ ์˜ํ–ฅ์š”์ธ ๋ณ€์ˆ˜๋“ค ๊ฐ„ ์ƒ๊ด€๋ถ„์„ 63 4.4 ์ž…์ฃผ์˜ˆ์ˆ ๊ฐ€๋“ค์˜ ๋„คํŠธ์›Œํฌ ํ˜„ํ™ฉ๊ณผ ๊ณต๊ฐ„์  ์กฐ๊ฑด๊ณผ์˜ ๊ด€๋ จ์„ฑ ์ธ์‹ 69 โ…ด. ๊ฒฐ๋ก  70 5.1 ์—ฐ๊ตฌ์˜ ๊ฒฐ๊ณผ 70 5.2 ํ–ฅํ›„ ์ฐฝ์ž‘ํด๋Ÿฌ์Šคํ„ฐ ์กฐ์„ฑ์‹œ์˜ ์‹œ์‚ฌ์  82 5.3 ์—ฐ๊ตฌ์˜ ํ•œ๊ณ„ 83Maste

Multipotent mesenchymal stromal cells (MSCs) have effective potentials of neuronal regeneration. Besides, chondroitinaseABC (chABC) and neuronal factors such as brain-derived neurotrophic factor (BDNF) are widely investigated to repair chronic SCI. Single treatments with those factors, for neurotropic effects or lysis of chondroitin sulfate proteoglycans as barrier to neuronal regeneration have been evaluated. It was hypothesized that combination therapy with factors having different traits could be more effective than single treatment. The studies were composed of two parts. First, combinational therapy of canine adipose tissue derived MSCs (cADMSCs) and chABC was evaluated in relation to functional recovery and neuronal regeneration. Second, local injections of chABC and BDNF-expressed cADMSCs with intravenous injection of cADMSCs were evaluated. In the first chapter, it was clarified that 5 U/mL chABC did not have a harmful effect on the viability of cADMSCs. The dogs treated with cADMSCs + chABC and cADMSCs showed significantly better functional recovery 8 weeks after transplantation compared with the negative control and chABC groups (p < 0.05). In addition, the combination of cADMSCs and chABC increased the expression of digested chondroitin sulfate proteoglycans (CSPGs), ฮฒ3-tubulin, and neurofilament microtuble (NF-M). However, the levels of cyclooxygenase2 (COX2) (p < 0.05) and tissue necrosis factor ฮฑ (TNFฮฑ) were higher in the treatment groups than in the control. Transplantation of cADMSCs + chABC was more effective in improving clinical signs and neural regeneration, but a strategy for anti-inflammation after the treatment for chronic SCI would be needed for further improvement. Higher expressions of inflammation markers could have negative effect on the microenvironment of the injured spinal cord. Neurotrophic factors were not detected even after transplantation of cADMSCs. To improve the clinical outcome after the SCI, the suitable methods that decrease inflammation and increase neurogenic factors are needed. In the second chapter, combinatorial transplantation of chABC and cADMSCs genetically modified to secrete BDNF with intravenous administration of cADMSCs were investigated. BDNF-expressing MSCs (MSC-BDNF) were generated using a lentivirus packaging protocol. The dogs in the chABC/MSC-BDNF included groups had significantly improved functional recovery 8 weeks after transplantation compared to those in the chABC/MSC-GFP group. The animals in the chABC/MSC-BDNF/IV group showed significant improvements in functional recovery at 6, 7, and 8 weeks compared to those in the chABC/MSC-BDNF group (p < 0.05). Fibrotic changes were significantly decreased in the chABC/MSC-BDNF/IV group. Significant decreases in the expression levels of TNFฮฑ, interleukin-6 (IL-6), COX2, gial fibrillary acidic protein (GFAP), and galactosylceramidase (GalC) and increased expression levels of BDNF, ฮฒ3-tubulin, NF-M, and nestin in the chABC/MSC-BDNF/IV group were observed. These findings suggested that degradation of the glial scar by chABC combined with the presence of neurotrophic factors released by of the transplanted MSCs secreting BDNF can enhance functional recovery after chronic SCI. It was demonstrated that lentiviral-mediated BDNF gene modification of cADMSCs allowed for stable BDNF production. In addition, chABC combined with cADMSCs transplantation, along with the IV administration of cADMSCs promoted clinical recovery in the injured spinal cord via microenvironment modification, anti-inflammation, and neuronal regeneration. Thus the combinatorial treatment of direct and intraveonus injections of BDNF expressing cADMSCs and chABC has a good therapeutic potential in the treatment of chronic SCI and this can be used as an alternative treatment modality in neuronal regeneration.BACKGROUNDS 1 CHAPTER I Effect of the combination of mesenchymal stromal cells and chondroitinaseABC on chronic spinal cord injury 13 ABSTRACT 13 INTRODUCTION 15 MATERIALS AND METHODS 17 1.

    Treatment of Urinary Incontinence after Radical Prostatectomy

    Get PDF
    Urinary incontinence is a significant complication following radical prostatectomy. Conservative treatments such as pelvic floor muscle exercise and pharmacologic therapy aim for early restoration of the pelvic floor and bladder function. Surgical treatment is advisable when significant and bothersome stress urinary incontinence persists even after 6 to 12 months of conservative treatment. Implantation of the artificial urinary sphincter is still the gold standard but still has significant complication and revision rates. Recently, new surgical techniques and materials are emerging aiming for those patients with less severe incontinence whom artificial urinary sphincter seem either too costly or invasive. This article summarize the latest issues in the treatment of urinary incontinence following radical prostatectomy.ope

Although there were many attempts to achieve functional restoration of voice, challenges to regenerate vocal fold still remains due to its unique tissue mechanical characteristics such as pliability that produces phonation via vibration. In this study, we developed mechanically compliant interpenetrating polymer network (IPN) hydrogel based on polyacrylamide (PAAM) and gelatin that matches physical and functional properties with native vocal fold tissue. The mechanical properties of this PAAM/gelatin (PG) hydrogel were modulated and optimized for vocal fold engineering by adjusting PAAM/gelatin ratio. In addition, PG hydrogel showed minimal foreign body reaction upon implantation, and the hydrogel displayed strong resistance to dehydration condition. Furthermore, PG hydrogel demonstrated self-healing ability that may allow ad-hoc implant augmentation. In addition, tough adhesion of PG hydrogel resulted in stable attachment to vocal fold tissues. Finally, we demonstrated the functional restoration of voice on ex vivo canine model by implanting PG hydrogel as an artificial vocal fold tissue.ํ›„๋‘์•”์œผ๋กœ ์ธํ•œ ์„ฑ๋Œ€ ์ ˆ์ œ์ˆ  ํ›„ ๋ชฉ์†Œ๋ฆฌ์˜ ์ƒ์‹ค์€ ์‚ถ์˜ ์งˆ์ด ๋‚ฎ์•„์ง€๋Š” ๋“ฑ์˜ ์‹ฌ๊ฐํ•œ ๋ฌธ์ œ๋“ค์„ ์•ผ๊ธฐํ•œ๋‹ค. ์ด๋ฅผ ๊ทน๋ณตํ•˜๊ธฐ ์œ„ํ•ด ์—ฌ๋Ÿฌ ๋ฐฉ๋ฒ•๋“ค์„ ํ†ตํ•œ ์Œ์„ฑ์˜ ๊ธฐ๋Šฅ์  ๋ณต์›์ด ์‹œ๋„๋˜์—ˆ์ง€๋งŒ, ์ง„๋™์„ ํ†ตํ•ด ์Œ์„ฑ์„ ์ƒ์„ฑํ•˜๋Š” ์„ฑ๋Œ€์˜ ์œ ์—ฐ์„ฑ๊ณผ ๊ฐ™์€ ๋…ํŠนํ•œ ๊ธฐ๊ณ„์  ํŠน์„ฑ์œผ๋กœ ์ธํ•ด ์Œ์„ฑ ํšŒ๋ณต์—๋Š” ์—ฌ์ „ํžˆ ๋งŽ์€ ๋ฌธ์ œ๋“ค์ด ๋‚จ์•„์žˆ๋‹ค. ์ด์— ์ด ๋…ผ๋ฌธ์—์„œ๋Š” ํด๋ฆฌ์•„ํฌ๋ฆด์•„๋งˆ์ด๋“œ์™€ ์ ค๋ผํ‹ด์˜ ๋น„์œจ์„ ์ตœ์ ํ™”ํ•˜์—ฌ ์„ฑ๋Œ€ ์กฐ์ง์˜ ๊ณ ์œ  ๋ฌผ๋ฆฌ์ ฮ‡๊ธฐ๋Šฅ์  ํŠน์„ฑ์„ ์ง€๋‹Œ ์ธ๊ณต ์กฐ์ง ํ•˜์ด๋“œ๋กœ๊ฒ”์„ ๊ฐœ๋ฐœํ•˜์˜€๋‹ค. ๋ณธ ์—ฐ๊ตฌ์˜ ํ•˜์ด๋“œ๋กœ๊ฒ”์€ ์„ฑ๋Œ€์™€ ์œ ์‚ฌํ•œ ๊ธฐ๊ณ„์  ํŠน์„ฑ๊ณผ ๋”๋ถˆ์–ด ๋†’์€ ์ƒ์ฒด์ ํ•ฉ์„ฑ๊ณผ ํƒˆ์ˆ˜ ์กฐ๊ฑด์— ๊ฐ•ํ•œ ์ €ํ•ญ์„ฑ์„ ๋ณด์˜€๋‹ค. ๋˜ํ•œ ์ด ํด๋ฆฌ์•„ํฌ๋ฆด์•„๋งˆ์ด๋“œ/์ ค๋ผํ‹ด ํ•˜์ด๋“œ๋กœ๊ฒ”์˜ ์ž๊ฐ€ ์น˜์œ ๋Šฅ์€ ์„ฑ๋Œ€์— ์ด์‹์‹œ ์ง€์†๋ ฅ์„ ๋ณด๊ฐ•ํ•ด์ฃผ์—ˆ๊ณ , ๊ฒฌ๊ณ ํ•œ ์ ‘์ฐฉ์„ฑ์€ ์„ฑ๋Œ€ ์กฐ์ง์— ์•ˆ์ •ํ•œ ๋ถ€์ฐฉ์„ ๊ฐ€๋Šฅํ•˜๊ฒŒ ํ–ˆ๋‹ค. ๋งˆ์ง€๋ง‰์œผ๋กœ ๋ณธ ์—ฐ๊ตฌ์˜ ํ•˜์ด๋“œ๋กœ๊ฒ”์„ ๊ฐœ๊ณผ ๋™๋ฌผ ๋ชจ๋ธ์˜ ์„ฑ๋Œ€์— ์ง์ ‘ ์ด์‹ํ•จ์œผ๋กœ์จ ์Œ์„ฑ๊ธฐ๋Šฅ์˜ ํšŒ๋ณต์„ ํ™•์ธํ•˜์—ฌ, ๊ฐœ๋ฐœ๋œ ํ•˜์ด๋“œ๋กœ๊ฒ”์ด ์„ฑ๋Œ€ ์œ ์‚ฌ ์ธ๊ณต์กฐ์ง์œผ๋กœ ํ™œ์šฉ๋  ์ˆ˜ ์žˆ๋‹ค๋Š” ๊ฒƒ์„ ์ž…์ฆํ•˜์˜€๋‹ค.Table of Contents 1.
