A Case of Multidrug-Resistant Salmonella enterica Serovar Typhi Treated with a Bench to Bedside Approach

윤희정,Soung Hoon Cho,Seong Han Kim 연세대학교의과대학 2009 Yonsei medical journal Vol.50 No.1

We report a relapsed case of a 25 year-old man with multi-drug resistant Salmonella serovar Typhi (MDRST) bacteremia who had recently returned from travel in India. Due to unresponsiveness to ciprofloxacin and ceftriaxone, we examined the strain’s resistance to quinolones and extended-spectrum β- lactamases (ESBLs). The strain had a single gyrA mutation at codon 83 (Ser83Phe), which explains its decreased susceptibility to fluoroquinolone and resistance to nalidixic acid. In the screening tests of ESBLs, TEM-1 was positive, which is beta-lactamase but not ESBL. The patient was finally successfully treated with meropenem and aztreonam. In the presence of clinical unresponsiveness despite favorable sensitivity tests, further laboratory evaluations are needed, which should include studies of genes related to antibiotic resistance and ESBLs. In addition, further prospective trials should be done about the possible inclusion of antibiotics not yet mentioned in the current guidelines. With MDRST on the rise worldwide, the most optimal and effective line of antibiotic defense needs to be devised.

日本語の授受動詞習得における母語の影響 -韓國人日本語學習者と中國人日本語學習者を比較して-

윤희정 한국일본어문학회 2009 日本語文學 Vol.41 No.-

本硏究は、日本語學習者の授受動詞の習得における母語の影響を授受本動詞と授受補助動詞ごとに檢討したものである。調査對象者は日本で日本語を學習している韓國人日本語學習者と中國人日本語學習者である。調査資料は學習者が繪をみて授受動詞文を書く文産出テストを用いた。その結果、授受本動詞と授受補助動詞の習得は學習者の母語によって異なるが、それは習得促進であり、習得順序は變わらないことがわかった。また授受本動詞の場合は韓國人學習者のほうが中國人學習者より習得が進んでいるのに對して授受補助動詞の場合は中國人學習者のほうが韓國人學習者より日本語母語話者の受益動詞の使用狀況(「てくれる」<「てもらう」)に早く近づいていくことがわかった。つまり、日本語の授受動詞の習得において母語の影響は授受本動詞の場合とそれが文法化した授受補助動詞の場合で異なっていた。

Widdrol에 의한 인간 자궁경부암 세포주의 Apoptosis 유도

윤희정,정종헌,권현주,현숙경,최영현,박정하,김병우 대한암예방학회 2011 Journal of cancer prevention Vol.16 No.3

In this study, the anticancer activity of widdrol, essential oil compound isolated from Juniperus chinensis,is investigated in human cervical cancer HeLa cells. Widdrol inhibits the growth of HeLa cells in a dose- and time-dependent manner. To confirm whether these effects of widdrol are associated with apoptosis, apoptotic features and expression of apoptosis-related proteins are examined. As a result, typical morphological characteristics of apoptotic cells such as formation of apoptotic body was observed as measured by DAPI staining. In Western blot analysis, the expression of anti-apoptotic Bcl-2 and Bcl-XL were decreased and cytosolic cytochrome c was increased in cells treated with widdrol. Also, caspase-8and caspase-9, which are initiator caspase each in extrinsic and intrinsic pathway, were activated, activation of executioner caspase (caspase-3) and proteolytic cleavage of PARP were also observed. Therefore,widdrol seems to induce apoptosis by activating both intrinsic and extrinsic pathway in HeLa cells at the same time. (Cancer Prev Res 16, 255-262, 2011)

윤희정,강동진,신상현 한국조경학회 2019 韓國造景學會誌 Vol.47 No.4

The purpose of this study is to determine urban walking tourists’ spatiotemporal movement densities and the stopping characteristics by season. With the Bukchon Hanok Village in Seoul, as the study site, a GPS-based smartphone application collected spatiotemporal data, and GIS and statistical methods were used to analyze the urban walking tourists’ spatiotemporal activities in the spring and summer. The results show that the moving and staying variables of urban walking tourists differ significantly by season. In addition, spatiotemporal movement densities and stopping characteristics using ArcGIS’s tools show clear spatial and temporal concentrations along the main access roads and commercial areas of the study site in the spring and summer. Policy-makers and developers of urban walking tours should use these spatiotemporal concentrations of walking tourists to define policies that would control the capacities of urban walking areas and distribute tourists spatially and temporally. 본 연구는 계절에 따라 도심 도보관광자들의 시․공간 이동밀도 및 멈춤 특성 분석을 주요 연구목적으로 한다. 이를 위해 본 연구는 서울 북촌한옥마을을 연구대상지로 선정하고, GPS 기반 스마트폰 어플리케이션을 활용하여 도심도보관광자들의 시․공간 행태 데이터를 수집하였다. 이에 기초하여 본 연구는 GIS와 통계적 접근방법을 이용하여 봄, 여름 도심 도보관광자들의 시․공간 이동행태를 분석하였다. 주요 연구결과, 도심 도보관광자들의 이동 및 체류특성은 계절별로 통계적 차이가 검증되었다. ArcGIS를 이용하여 도심 도보관광자의 시․공간적 이동밀도와 멈춤 특성을 분석한 결과, 대상지로의 중심 접근로와 상업공간에 있어 공간적․시간적 집중성이 확인되었다. 도심 도보관광관련 정책입안자나 개발자들은 본 연구결과의 시․공간 밀집도를 활용하여 도보관광지의 수용력 조절이나 관광자들의 공간적 혹은 시간적 분산정책 수립에 활용할 수 있을 것이다.

윤희정,박정철,윤정호,정의원,김창성,최성호,조규성 대한치주과학회 2011 Journal of Periodontal & Implant Science Vol.41 No.5

Purpose: The marginal bone levels around implants following restoration are used as a reference for evaluating implant success and survival. Two design concepts that can reduce crestal bone resorption are the microthread and platform-switching concepts. The aims of this study were to analyze the placement of microthreaded and platform-switched implants and their short-term survival rate, as well as the level of bone around the implants. Methods: The subjects of this study were 27 patients (79 implants) undergoing treatment with microthreaded and platformswitched implants between October 2008 and July 2009 in the Dental Hospital of Yonsei University Department of Periodontology. The patients received follow-up care more than 6 months after the final setting of the prosthesis, at which time periapical radiographs were taken. The marginal bone level was measured from the reference point to the lowest observed point of contact between the marginal bone and the fixture. Comparisons were made between radiographs taken at the time of fixture installation and those taken at the follow-up visit. Results: During the study period (average of 11.8 months after fixture installation and 7.4 months after the prosthesis delivery),the short-term survival rate of microthreaded and platform-switched implants was 100% and the marginal bone loss around implants was 0.16±0.08 mm, the latter of which is lower than the previously reported values. Conclusions: This short-term clinical study has demonstrated the successful survival rates of a microthread and platformswitched implant system, and that this system is associated with reduced marginal bone loss.

Vaccines against Coccidioides

윤희정,Karl V. Clemons 대한내과학회 2013 The Korean Journal of Internal Medicine Vol.28 No.4

Vaccines against fungal diseases are gaining attention because of their growing impact on modern medicine. Development of these vaccines should incorporate immunological tools that integrate with or replace chemotherapy to minimize antibiotic use and consequent resistance. In this review, we evaluate the current developmental status of fungal vaccines against coccidioidomycosis. There is a need for a vaccine that sufficiently prevents disease, without eradicating the fungus,by neutralizing adhesions and enzymes or other low penetrance virulence traits.
