Research on the nutritional components of agri-food used as raw materials for health functional foods is gaining importance with the growing interest in such foods. However, there is limited information available on one such nutritional component, namely water-soluble vitamin B. Therefore, this study used the high-performance liquid chromatography (HPLC) analytical method to evaluate the thiamine, riboflavin, and niacin contents in agri-food, which is mainly used as a raw material for health functional food. Among the samples used in this study, red ginseng had the highest thiamine content at 0.515±0.010 mg/100 g, followed by Cordyceps (husked rice) with 0.302±0.014 mg/100 g. Cordyceps (silkworm pupa; 0.288±0.011 mg/100 g) contained the most riboflavin, followed by lion’s mane mushroom at 0.256±0.006 mg/100 g. Niacin was detected in all samples, with ginger (1.521±0.007 mg/100 g) having the highest content. The results of this study will be used as a database for the compilation of the 10th edition of the Korean Food Composition table and will hence contribute to improving public health. 건강 기능성 식품에 관한 관심이 증가함에 따라 농식품의 영양성분 연구가 활발히 이루어지고 있음에도 불구하고 수용성비타민 B에 대한 정보는 미비한 실정이다. 따라서 본 연구는 건강 기능성 식품의 원료로 이용되는 농식품에 함유된 티아민, 리보플라빈 및 니아신의 정량 분석법을 검증하고 그 함량을 평가하였다. 그 결과, 티아민이 가장 많이 함유된 것은 홍삼(0.515±0.010 mg/100 g)이었으며, 다음으로 동충하초(현미; 0.302±0.014 mg/100 g)의 순이었고, 동충하초(현미)의 경우 상황버섯 침출액(0.300±0.005 mg/100 g) 및 편강(0.284±0.008 mg/100 g)과 통계적 차이가 인정되지 않았다. 리보플라빈이 가장 많이 함유된 것은 동충하초(누에번데기; 0.288±0.011 mg/100 g)였으며, 다음으로 노루궁뎅이 버섯(0.256±0.006 mg/100 g)의 순이었다. 니아신의 경우 본 연구에서 검토된 모든 시료군에서 검출되었고 생강(1.521±0.007 mg/100 g)이 가장 높은 함량을 나타내었다. 본 연구의 결과는 향후 국가표준식품성분표 제10개정판 출간에 활용될 것이며, 대국민 식생활 홍보 및 증진에 기여할 수 있을 것이다.

전진수,김해현,차영욱,김춘희,정유현,Jeon, Jin-Su,Kim, Hae-Hyun,Cha, Young-Wook,Kim, Choon-Hee,Jeong, You-Hyeon 한국정보처리학회 2008 정보처리학회논문지 C : 정보통신,정보보안 Vol.15 No.5

NGN is a packet-based converged network to support session and non-session services in QoS-enabled broadband transport network. QoS based resource control must be defined to support differentiated services for various network users in NGN. We designed and implemented DIAMETER protocol as the Rs interface, and also defined mapping rules between DIAMETER information elements and SDP(Session Description Protocol) attributes for QoS based resource control in NGN. We selected and implemented DIAMETER protocol among alternate resource control protocols in ITU-T as the Rw interface because of simple interworking method with Rs interface and adequate AAA functionality. We defined mapping rules of messages and information elements between Rs and Rw interfaces for resource control from a service layer to a transport layer. Based on the mapping rule of QoS information elements and the interworking method between Rs and Rw interfaces, we built up a test-bed that support differentiated delivery services. NGN은 QoS가 지원되는 광 대역 전달 망에서 세션 및 비-세션 서비스를 지원하기 위한 패킷 기반의 융합 망이다. NGN에서 네트워크 사용자에 따라 차별화된 서비스를 제공하기 위해서는 QoS 기반 자원제어가 이루어져 한다. 본 논문에서는 DIAMETER를 이용하는 Rs 인터페이스의 자원제어 프로토콜을 설계 및 구현하였으며 NGN에서 QoS 기반 자원제어를 위하여 DIAMETER 정보요소와 세션제어 프로토콜인 SIP의 SDP 속성들의 매핑방안을 제시하였다. Rs 인터페이스와의 연동 용이성과 다양한 기능성을 고려하여 ITU-T에서 제시한 자원제어 프로토콜 중에서 Rw 인터페이스는 DIAMETER를 이용하는 자원제어 프로토콜을 구현하였다. 또한, 서비스 층에서 전송 층으로 자원제어를 위하여 Rs와 Rw 인터페이스 사이의 메시지 및 정보요소의 매핑방안을 제시하였다. 본 논문에서 제시한 QoS 정보요소의 매핑 방안과 Rs와 Rw 인터페이스의 연동 방안을 이용하여 차별화된 전송 서비스를 제공하는 NGN 자원제어 테스트-베드를 구축하였다.

Hemorrhage in the Cisterna Magna after Acupuncture

전진수,홍승관,조성민,조용준 대한신경외과학회 2004 Journal of Korean neurosurgical society Vol.36 No.5

Acupuncture is one of the most popular complimentary therapies these days not only in Asia, but also in USA and Europe. Acupuncture is generally regarded as a safe procedure in the general public. However, acupuncture is not free of risk; complications of acupuncture have been repeatedly reported in the medical literatures. The authors report a rare case of hemorrhage in the cisterna magna after acupuncture. Acute frontal headache, dizziness, neck pain, neck stiffness, and paresthesia or tingling discomfort at arms and legs developed immediately after an acupuncture treatment that had been performed to treat her chronic posterior neck pain. Computerized tomography scans and magnetic resonance images(MRI) showed a 1.2 0.8cm-sized high density and high signal mass within the cisterna magna. It is probable that the acupuncture needle had been inserted deep enough to enter the cisterna magna and provoked a small hemorrhage in the cistern. She gradually recovered from the symptoms. Physicians and acupuncture therapists should be aware of the adverse events associated with acupuncture.

Hemodynamic Instability during Carotid Angioplasty and Stenting-Relationship of Calcified Plaque and Its Characteristics

전진수,신승훈,황교준 연세대학교의과대학 2013 Yonsei medical journal Vol.54 No.2

Purpose: During carotid angioplasty and stenting (CAS), hemodynamic instability (HDI) can occur, possibly causing post-procedural ischemic complications. The goal of this study was to investigate the risk factors of HDI focusing on characteristics of plaque. Materials and Methods: Thirty nine CAS patients were retrospectively evaluated for HDI. Prolonged HDI that lasted over 30 minutes was analyzed in relation to characteristics of calcified plaque. Results: Nineteen (48.7%) patients had HDI. Ten of the 19 had both bradycardia and hypotension, and nine had only bradycardia. All bradycardia was treated well with a transcutaneous temporary cardiac pacemaker. But eight patients presented with prolonged hypotension in spite of recovery of bradycardia. Calcified plaque was a related factor associated with HDI (odds ratio, 8.571; 95% confidence interval, 1.321-55.62; p=0.024). Extensive and eccentric type calcified plaques were associated with prolonged hypotension (p=0.04, and p=0.028, respectively). Conclusion: The calcification of plaque is a predictable factor of HDI during CAS, and its extensive and eccentric calcified plaques may be related to prolonged HDI.

Impact of Dementia on Mortality Due to Coronavirus Disease 2019: Propensity-Score-Matching Study

전진수,이수정,김철호 대한신경과학회 2022 Journal of Clinical Neurology Vol.18 No.1

Background and Purpose Patients with dementia are particularly vulnerable to coronavirus disease 2019 (COVID-19) because they tend to be older and often have concomitant diseases. Previous studies have investigated the impact of dementia on COVID-19 outcomes, but the evidence is not robust for Asian populations. We aimed to determine the relationship between dementia and COVID-19 outcomes using data from a large-scale nationwide public database. Methods Data on patients with COVID-19 who were released from quarantine between January 1, 2020 and April 30, 2020, published by the Korea Disease Control and Prevention Agency, were divided into two groups based on the dementia status. Propensity-score matching was used to adjust for multiple confounders between the dementia and no-dementia groups. Binary, ordinal logistic regression and multivariate Cox proportional-hazards models were used to compare mortality, quarantine duration, and clinical deterioration according to the dementia status in the two groups. Results Males and older individuals (age ≥60 years) constituted 41.5% and 32.9%, respectively, of the 5,299 patients. The prevalence of dementia was 4.2%, and 4.5% of the participants died during hospitalization. In multivariate analysis, dementia was significantly associated with increased mortality (odds ratio [OR]=2.80, 95% confidence interval [CI]=1.60–4.60), longer duration of quarantine (hazard ratio=1.69, 95% CI=1.16–2.45), and larger shift to a worse clinical severity (common OR=1.74, 95% CI=1.18–2.61). Conclusions After adjusting for important clinical predictors, dementia was associated with increased in-hospital mortality, duration of quarantine, and clinical deterioration during hospitalization in COVID-19 patients.

Intraarterial Tirofiban Thrombolysis for Thromboembolisms During Coil Embolization for Ruptured Intracranial Aneurysms

전진수,신승훈,Gyojun Hwang,강석형,Dong Hwa Heo,조용준 대한뇌혈관외과학회 2012 Journal of Cerebrovascular and Endovascular Neuros Vol.14 No.1

Objective: Thromboembolus can occur during endovascular coil embolization. The aim of our study was to show our experience of intraarterial (IA) tirofiban infusion for thromboembolism during coil embolization for ruptured intracranial aneurysms. Methods: This retrospective analysis was conducted in 64 patients with ruptured aneurysms who had emergent endovascular coil embolization from May 2007 to April 2011 at a single institute. Thromboembolic events were found in ten patients (15.6%). Anticoagulation treatment with intravenous heparin was started after the first coil deployment in ruptured aneurysmal sac. When a thrombus or embolus was found during the procedure, we tried to resolve them without delay with an initial dosage of 0.3 mg of tirofiban up to 1.2 mg. Results: Three patients of four with total occlusion had recanalizations of thrombolysis in myocardial infarction (TIMI) grade III and five of six with partial occlusion had TIMI grade III recanalizations. Eight patients showed good recovery, with modified Rankin Scale (mRS) score of 0 and one showed poor outcome (mRS 3 and 6). There was no hemorrhagic or hematologic complication. Conclusion: IA tirofiban can be feasible when thromboembolic clots are found during coil embolization in order to get prompt recanalization, even in patients with subarachnoid hemorrhage.
