Reports on the comparison of clinical effect between non-surgical and surgical therapy, and the change of the clinical parameters during maintenance phase have been rarely presented in Korea. This study was to observe the clinical changes during maintenance phase of 6 months in patients with chronic periodontitis treated by non-surgical or surgical therapy in Department of Periodontics, Chonnam National University Hospital. Among the systemically healthy and non-smoking patients with moderate to severe chronic periodontitis, twenty eight patients (mean age: 47.5 years) treated by non-surgical therapy (scaling and root planning) and nineteen patients (mean age: 47.3 years) treated by surgical therapy (flap surgery) were included in this study. The periodontal supportive therapy including recall check and oral hygiene reinforcement was started as maintenance phase since 1 month of healing after treatment. Probing depth, gingival recession. clinical attachment level and tooth mobility were recorded at initial, baseline and 1, 2, 3 and 6 month of maintenance phase. The clinical parameters were compared between the non-surgical and surgical therapies using Student t-test and repeated measure ANOVA by initial probing depth and surfaces. Surgical therapy resulted in greater change in clinical parameters than non-surgical therapy. During the maintenance phase of 6 months, the clinical effects after treatment had been changed in different pattern according to initial probing depth and tooth surface. During maintenance phase, probing depth increased more and gingival recession increased less after surgical therapy, compared to non-surgical therapy. The sites of initial probing depth less than 3 mm lost more clinical attachment level, and the sites of initial probing depth more than 7 mm gained clinical attachment level during maintenance phase after non-surgical therapy, compared to surgical therapy. Non-surgical therapy resulted in greater reduction of tooth mobility than surgical therapy during maintenance phase. These results indicate that the clinical effects of non-surgical or surgical therapy may be different and may change during the maintenance phase.

Purpose: To evaluate the clinical outcomes of patients with diffractive multifocal toric intraocular lens (IOL) implantation. Methods: Thirty-four eyes of 26 patients underwent diffractive multifocal toric IOL. Uncorrected visual acuity (UCVA) at distant, intermediate and near and residual refractive astigmatism were measured on the first day, at 2 weeks, and 1, 3 and 6 months postoperatively. Optical quality obtained using the Optical Quality Analysis System II (OQAS II), high-order aberrations (HOA) and patient satisfaction questionnaire were evaluated 3 months postoperatively. Results: At the 6 month postoperative visit, the mean UCVA at distant, intermediate (63 cm, 100 cm) and near were 0.06 ± 0.07, 0.18 ± 0.11, 0.16 ± 0.12 and 0.03 ± 0.06 (log MAR), respectively. The refractive astigmatism decreased significantly from -1.66 ± 1.04 D to -0.54 ± 0.32 D at 6 months postoperatively (<em>p</em> < 0.01). The means of objective scatter index, modulation transfer function (MTF) cut-off value, Strehl ratio and pseudo-accommodation range measured by OQAS II were 1.33 ± 0.67, 37.24 ± 9.67 cdp, 0.22 ± 0.09 and 3.08 ± 0.53 D, respectively. HOA scores for 5 mm and 6 mm were 0.30 ± 0.09 and 0.49 ± 0.15, respectively; 82.3% of the patients were satisfied with the postoperative results, 79.4% of the patients reported they would recommend the procedure to others, and 14.7% of patients reported moderate or severe visual disturbance at night. Conclusions: Implantation of a diffractive multifocal toric IOL in patients with cataract and corneal astigmatism provided excellent distant, intermediate, and near visual outcomes, good optical quality and high patient satisfaction.

무선 센서 네트워크는 언제, 어디에서든, 때와 장소를 가리지 않고 사용자가 원하는 서비스를 제공해주는 시스템이다. 특히, 바이오 센서를 이용한 의료센서네트워크는 생명공학, 의료공학 분야에서 활발하게 활용이 되고 있다. 의료센서네트워크에서는 사용자가 시간적이나 공간적 제약을 받지 않고 집에서 건강을 모니터링 할 수 있는 환경이다. U-healthcare환경에서 긴급 상황이 발생 했을 때 빠르게 환자를 도와줄 수 있으며, 병원에서도 손쉽게 환자를 관리 할 수 있다는 장점을 갖는다. 이 환경에서는 개인의 건강과 생명에 직결된 데이터가 송수신되므로 개인의 프라이버시 보장과 데이터의 보안이 가장 중요한 요소이다. 본 논문에서는 휴대폰을 이용한 사용자 인증 방안과 데이터의 종류에 따라 긴급모드와 일반모드의 구분을 두어 안전하면서도 빠르게 데이터를 전송하는 방안을 제안하였다. Wireless sensor network provides services anytime and anywhere they are requested. Especially, medical sensor network based on biosensors is applied a lot to biotechnology and medical engineering. In medical sensor network, people can make their health checked at home free from temporal and spatial constraints. In ubiquitous healthcare environment, people can get instant help even in the emergency, and in hospital, patients can be taken care of efficiently. In this environment, health and life related data are delivered, and the privacy and security of personal data are very important. In this paper, we propose user authentication and data communication mechanism in two modes, normal and urgent situation using cellular phone. Through our proposal, data can be transferred in quick and secure manner.

Purpose: To determine the difference in subfoveal choroidal thickness between two spectral-domain optical coherence tomography (SD-OCT) systems in normal eyes and eyes with retinal diseases. Methods: Thirty-three normal eyes and 49 eyes with retinal disease (13 eyes with diabetic retinopathy, 28 eyes with epiretinal membrane and eight eyes with macular hole) were enrolled in the study. Subfoveal choroidal thicknesses were measured by 3 observers using the enhanced depth imaging technique of Heidelberg Spectralis<sup><font size=`2`>Ⓡ </font>and the high-definition five-line raster scan of Cirrus HD-OCT<sup><font size=`2`>Ⓡ</font> using calipers within the program. Differences between the measured values were analyzed with a paired t-test in PASW 18.0. Results: The mean age of normal eyes was 67.31 years, while eyes with diabetic retinopathy, epiretinal membrane and macular hole were aged 56.08 years, 70.00 years and 68.50 years, respectively. The mean subfoveal choroidal thickness of normal eyes was 237.61 ± 104.60 μm for Spectralis and 239.52 ± 92.08 μm for Cirrus and showed no significant difference (<em>p</em> = 0.397). Eyes with diabetic retinopathy, epiretinal membrane, and macular hole measured 267.46 ± 74.91 μm, 236.79 ± 84.16 μm and 209.63 ± 86.71 μm for Spectralis, respectively, and 266.69 ± 73.76 μm, 226.75 ± 77.30 μm and 206.75 ± 78.69 μm for Cirrus. They also showed no statistical difference (<em>p</em> > 0.05). Conclusions: Subfoveal choroidal thickness measurements according to Heidelberg Spectralis<sup><font size=`2`>Ⓡ</font> and Cirrus HD-OCT<sup><font size=`2`>Ⓡ</font> in both normal eyes and eyes with retinal diseases showed no significant differences.

Aortic aneurysm-induced chronic consumptive coagulopathy is a very rare complication but can be a source of critical complications and mortality. A 72-year-old man presented with a rapidly expanding descending thoracic aortic aneurysm with a penetrating ulcer and an infrarenal abdominal aortic aneurysm complicated by chronic coagulopathy. We were aware of the bleeding risk during surgical replacement based on the patient’s chronic coagulopathy status and successfully performed endovascular repair of the thoracic aortic aneurysm with a penetrating ulcer. Platelet transfusion, antiplatelet agents, and proteinase inhibitors improved the coagulopathy. A delayed type Ib endoleak developed, and the coagulopathy recurred 2 months later when the patient presented with purpura of both lower legs. We successfully managed the condition by elective surgical replacement of the entire aorta after improving the coagulopathy with platelet replacement and administration of proteinase inhibitors.

This study aims to investigate the development of the corporate governance of investment funds in Korea (Republic of Korea), especially dealing with the mutual fund among the various type of investment funds to evaluate its effectiveness and needs to revitalize the mutual fund. Ever since the 1997 economic crisis, all financial companies of Korea have launched several systems such as outside director system and compliance officer system to improve the transparency of management accordingly with intensive business restructuring. These efforts were designed to improve the backwardness of Korean corporate governance to meet the global standards. Answering to these societal demands, the investment funds also have applied the mutual fund since 1998. However, despite the immediate popularity for its transparency, right after the 1997 crisis, the mutual fund has been avoided by investment banks for its structural demerit of high expenditure even if its merit of maximizing the interest of shareholders. Moreover, the investment trust also has improved its governance structure by applying the general meeting of beneficiaries system. This resulted in the indifference of investor protection between the mutual funds and the investment trusts. Not only the investment bankers but the individual investors who are sensitive to yields also have avoided investment funds because of the high expenditure to operate. Hence, most indirect investments of Korea are employing the investment trust as it had been before the 1997 crisis. However, considering the difference between mutual fund, as the US model which maximizing the shareholder value and shareholder profit, and investment trusts, as the UK model which aims to long-term shareholder value and self-regulatory governance, such as the origin of each system and their tools for shareholder protection, it is doubtful to conclude that the investment trust provides the equal improvement of the governance and investor protection to the mutual funds. To answer this question, this study demonstrates what differences lie between the mutual fund and the investment trust through a comparative analysis of pros and cons of two systems to evaluate the needs to revitalize the mutual funds. Further, this study suggests the possible solutions to revitalize the mutual funds in Korean economy.

This thesis aims to observe how the relationship between Hamlet and Ophelia, the double, leads Hamlet to the way to a tragedy. It also highlights Hamlet's transformation as a symbol of the words, and Ophelia's split from him to become a symbol of emotional song-speech. Hamlet, though his poetic dictions are heightened to the peak of the words, is not able to reach the level of Ophelia's musical song-speech until he is reunited with Ophelia at her grave. Meanwhile, previous studies tend to regard Laertes as the double of Hamlet. Laertes, being objectified as love and jealousy by Hamlet, is a double of Hamlet possessing desire to revenge, with an affection for Ophelia. Hamlet decouples Ophelia from himself to accomplish his ultimate aim, murdering Claudius: but this decoupling also signifies his split from the desire, which is essential to make him act for the revenge. As the result of this split, Hamlet stays at the stage of the linguistic mimesis that estranges him from the real purpose, and this mimesis makes him go blind not to distinguish the representing and the represented. Theoretically, this thesis is indebted to Bradley's traditional character theory, Lacanian psychoanalytic theory, and Weimann's theory of mimesis.

After obtaining permission for construction from administrative agency, a developer makes a capital financing contract with project lenders. In case a developer becomes insolvent, project lenders would make every effort to take over the project implement rights, so they can get repayment. This article examines if it is necessary to include the project implement rights transfer provision in such contracts, and shows the examples of transfer provision in contracts. It also suggests the legal approaches for taking over project implement right, such as suits for transfer rights and title transfer, and it looks through the range of acceptance and reconciliation. In addition, the research studies the possibility of transfer project implement right to project lenders inferring with Ipso facto clause, in case of the developer or the constructor`s bankruptcy. Finally, the research investigates the way for project lenders to secure the construction permission when the corporate recovery proceeds. It briefly introduces corporate recovery procedure, then shows the effect of transferring project implement right clause, obtaining the business through buying securities(debt-equity swap, enforcement of the pledge), managemental real estate trust.

Immunosuppressive agents and biological agents are widely used for therapy in patients with inflammatory bowel disease (IBD). However, these therapies may be associated with an increased risk of malignancy. There is evidence that exposure of the therapeutic agents such as thiopurine and anti-tumor necrosis factor for IBD is associated with an increased risk of lymphoproliferative disorders, skin cancers, or uterine cervical cancers. This article reviews the malignancies associated with the use of immunosuppressive agents and biological agents in IBD. (Korean J Gastroenterol 2017;70:162-168)
