북한 급변사태 가능성과 우리의 대응방안

김관호(Kim Kwan Ho) 북한학회 2016 북한학보 Vol.41 No.2

과거 동구권 사회주의 붕괴, 김일성ㆍ김정일 사망 등 북한에서 심각한 정치ㆍ경제적 변고가 있다는 소식이 전해지면 급변사태에 대한 관심이 고조되어 왔다. 그러나 북한은 이를 비웃듯 김정은이 3대 세습을 성공시키며 아직까지도 체제를 유지하고 있다. 하지만, 올해 1월초 북한은 4차 핵실험으로 인해 국제사회의 강력한 제재와 고립정책으로 인해 큰 위기국면에 직면해 있다. 지속되는 경제난과 국제사회의 강력한 대북제재로 인한 압박이 해외주재원들의 외화상납 강요 등으로 연결된 결과, 중국 내 북한식당 종업원들의 집단탈북, 러시아와 영국 주재 외교관들의 탈북이 잇따르고 있다. 이와 더불어 지난 9월 북한의 5차 핵실험이 감행되면서 한국 내 전략핵무기 배치 및 독자적인 핵개발 여론이 조성되고 있으며, 미국의 선제타격론이 제기되는 등 북한을 한층 더 강하게 압박하고 있다. 아울러 일각에서 조심스럽게 급변사태를 논의하는 것은 북한의 급변을 남북통일로 발전시킬 수도 있을 것으로 판단하기 때문일 것이다. 따라서 본 연구에서는 북한의 급변사태 발생 가능성과 예측 가능한 시나리오를 상정하고 이에 대한 우리정부의 대응방안을 제시하였다. In the past, attention on contingencies has been elevated when the news spread that there were serious political and economic changes in NK such and the collapse of socialism in the eastern bloc or death of Kim-Il-Sung and Kim Jeong-Il. Contrary to expectations KJU success fully succeeded his predecessors and has maintained the regime for three consecutive generations as if it is laughing in our faces. However, In January this year, NK faced a grave situation from the international community’s strong sanctions and isolation policy, which were results of the 4th NK nuclear test. Because continued economic hardship and the pressure from the international community’s NK sanctions led officials placed overseas to forcibly offer bribes in foreign currencies, NK restaurant employees in China and diplomats in Russia and UK are defecting from NK one after another. In addition, 5th NK nuclear test in September created public opinion for the deployment of strategic nuclear weapons in the Republic of Korea and indigenous development of such forces. The proposal of pre-emptive strike from the US also adds to the pressure that is placed upon NK. Some people carefully discuss contingencies in NK because it can be seen that those events may develop a reunification of the Korean Peninsula. Therefore, this study assumed the possibility of contingencies in NK and expected scenarios to propose ROK government’s response measures.

Development of a Virtual Reference Station-based Correction Generation Technique Using Enhanced Inverse Distance Weighting

Tae, Hyunu,Kim, Hye-In,Park, Kwan-Dong The Institute of Positioning 2015 Journal of Positioning, Navigation, and Timing Vol.4 No.2

Existing Differential GPS (DGPS) pseudorange correction (PRC) generation techniques based on a virtual reference station cannot effectively assign a weighting factor if the baseline distance between a user and a reference station is not long enough. In this study, a virtual reference station DGPS PRC generation technique was developed based on an enhanced inverse distance weighting method using an exponential function that can maximize a small baseline distance difference due to the dense arrangement of DGPS reference stations in South Korea, and its positioning performance was validated. For the performance verification, the performance of the model developed in this study (EIDW) was compared with those of typical inverse distance weighting (IDW), first- and second-order multiple linear regression analyses (Planar 1 and 2), the model of <xref>Abousalem (1996)</xref> (Ab_EXP), and the model of <xref>Kim (2013)</xref> (Kim_EXP). The model developed in the present study had a horizontal accuracy of 53 cm, and the positioning based on the second-order multiple linear regression analysis that showed the highest positioning accuracy among the existing models had a horizontal accuracy of 51 cm, indicating that they have similar levels of performance. Also, when positioning was performed using five reference stations, the horizontal accuracy of the developed model improved by 8 ~ 42% compared to those of the existing models. In particular, the bias was improved by up to 27 cm.

영남대학교 의료원 치료방사선과에서 1988년 6월 15일에 위함 환자의 수술중 방사선치료를 시작한 이래 1992년 8월 30일까지 총 58예에서 시도하여 그중 53예에서 IORT를 실시하였으며, 정기적인 추적검사에서 한명의 국소개발 환자도 보고되지 않고 있다. 출혈(3예), 장관폐쇄(3예), 폐혈증(2예), 골수기능저차(1예)를 포함한 총 9예(17%)의 합병증이 보고되었고, 이중 6예(13%)가 사망하였다. IORT(1500cGy), 외부 방사선치료 (-4500cGy)와 강한 항암제를 병합치료 하였음에도 불구하고 주등(수술과 항암제 치료)의 25.2%, 김등(수술 불가능한 환자에서 항암제 투여)의 18%, 리등(수술)의 18.5%, Kraming등(IORT 2800-3500cGy)의 35.3%에 비해 낮은 합병증을 보여 IORT가 위암의 치료에 공헌할 수 있음을 시사하였다. 그러나 비교적 높은 치사율(11.3%)은 더욱 세심한 수술수기 및 수술 후 환자의 치료가 필요하며 외부 방사선치료와 항암제치료의 적절한 시기 조절 및 치료선량의 가감이 필요할 것으로 생각된다. Local control is the important prognostic factor in cancer treatment because local control decrease the relative risk of metastatic spread and increase distant metastasis free survival. IORT is the modality which could increase local control without increasing complication, combined with curative operation. Eventhough we could achieve significant deacreased local failure by IORT and curative resection, it should not be committed as a main treatment modality without proving acceptable complications. Therapeutic Radiology Department of Yeungnam University Medical Center have tried 58 IORT from June 15, 1988 and performed 53 IORT in patients with gastric cancer. No local failure had been reported including interstinal obstrution, hemorrhage, sepsis, and bone marrow depression. These complications could be comparable to Jo's 25.2% (chemotherapy + operation), Kim's 18% (chemotherapy only in inoperable patients), because our treatment regimen is consisted of IORT (1500cGy), external irradiation (--4500cGy) and extensive chemotherapy (FAM, 5FU + MMC, BACOP). Our data encouraged us to re-inforce further IORT in stomach cancer treatment.

Background and Purpose Long-term changes in post-stroke depression (PSD), post-stroke emotional incontinence (PSEI), and post-stroke anger (PSA) have rarely been studied. Methods This is a sub-study of EMOTION, a randomized, placebo-controlled trial, that examined the efficacy of escitalopram on PSD, PSEI, and PSA in patients with stroke. We interviewed patients at the long-term period (LTP) using predefined questionnaires: Montgomery-Åsberg depression rating scale (MADRS) for PSD, modified Kim’s criteria for PSEI, and Spielberger trait anger scale for PSA. Additionally, the ENRICHD Social Support Instrument (ESSI) for the social support state and the modified Rankin Scale (mRS) were measured. We investigated the changes in and factors behind PSD, PSEI, and PSA at LTP. Results A total of 222 patients were included, and the median follow-up duration was 59.5 months (interquartile range, 50 to 70). Compared to the data at 6 months post-stroke, the prevalence of PSEI (11.7% at 6 months, 6.3% at LTP; P=0.05) and mean anger score (21.62, 16.24; P<0.01) decreased, while the prevalence of PSD (35.6%, 44.6%; P=0.03) and mean MADRS (6.16, 8.67; P<0.01) increased at LTP. ESSI was associated with PSD and PSA, but not with PSEI. The effect of the baseline National Institutes of Health Stroke Scale score on PSD decreased over time. The effect of low social support on PSD was greater than that of mRS at LTP. Conclusions The prevalence and degree of PSD significantly increased, while those of PSEI and PSA decreased at LTP. PSD in this stage appeared to be more closely associated with a lack of social support than patients' physical disabilities.

Kim, Hyun-Jin,Kim, Sei-Won,Lee, Hye-Yeon,Kang, Hyeon-Hui,Kang, Ji-Young,Kim, Ju-Sang,Kim, Myung-Sook,Kim, Seung-Soo,Kim, Jin-Woo,Yun, Hyeong-Gyu,Kim, Chi-Hong,Kim, Kwan-Hyoung,Moon, Hwa-Sik,Cho, Kwang The Korean Academy of Tuberculosis and Respiratory 2012 Tuberculosis and Respiratory Diseases Vol.72 No.6

Background: The aim of this study was to analyze clinical situations requiring rigid bronchoscopy and evaluate usefulness of rigid bronchoscopic intervention in benign or malignant airway disorders. Methods: We retrospectively reviewed 29 patients who underwent rigid bronchoscopy from November 2007 to February 2011 at St. Paul's Hospital, The Catholic University of Korea School of Medicine. Results: Of the 29 patients, the most frequent underlying etiology was benign stenosis of trachea (n=20). Of those 20 patients, 16 had post-intubation tracheal stenosis (PITS), 2 had tracheal stenosis due to inhalation burn (IBTS) and other 2 had obstructive fibrinous tracheal pseudomembrane (OFTP). Other etiologies were airway malignancy (n=6), endobronchial stenosis due to tuberculosis (n=2), and foreign body (n=1). For treatment, silicone stent insertion was done in 16 cases of PITS and IBTS and mechanical removal was performed in 2 cases of OFTP. In 6 cases of malignant airway obstruction mechanical debulking was performed and silicone stents were inserted additionally in 2 cases. Balloon dilatation and electrocautery were used in 2 cases of endobronchial stenosis due to tuberculosis. In all cases of stent, airway obstructive symptom improved immediately. Granulation tissue formation was the most common complication. Conclusion: Tracheal stenosis was most common indication and silicone stenting was most common procedure of rigid bronchoscopy in our center. Rigid bronchoscopic procedures, at least tracheal silicone stenting, should be included in pulmonary medicine fellowship programs because it is a very effective and indispensable method to relieve critical airway obstruction which needs training to learn.

Brazilin Isolated from Caesalpinia sappan suppresses nuclear envelope reassembly by inhibiting barrier-to-autointegration factor phosphorylation.

Kim, Seong-Hoon,Lyu, Ha-Na,Kim, Ye Seul,Jeon, Yong Hyun,Kim, Wanil,Kim, Sangjune,Lim, Jong-Kwan,Lee, Ho Won,Baek, Nam-In,Choi, Kwan-Yong,Lee, Jaetae,Kim, Kyong-Tai American Society for Pharmacology and Experimental 2015 The Journal of Pharmacology and Experimental Thera Vol.352 No.1

<P>To date, many anticancer drugs have been developed by directly or indirectly targeting microtubules, which are involved in cell division. Although this approach has yielded many anticancer drugs, these drugs produce undesirable side effects. An alternative strategy is needed, and targeting mitotic exit may be one alternative approach. Localization of phosphorylated barrier-to-autointegration factor (BAF) to the chromosomal core region is essential for nuclear envelope compartment relocalization. In this study, we isolated brazilin from Caesalpinia sappan Leguminosae and demonstrated that it inhibited BAF phosphorylation in vitro and in vivo. Moreover, we demonstrated direct binding between brazilin and BAF. The inhibition of BAF phosphorylation induced abnormal nuclear envelope reassembly and cell death, indicating that perturbation of nuclear envelope reassembly could be a novel approach to anticancer therapy. We propose that brazilin isolated from C. sappan may be a new anticancer drug candidate that induces cell death by inhibiting vaccinia-related kinase 1-mediated BAF phosphorylation.</P>

Kim, Hyo Bin,Jeong, Jeong Kyo,Kim, Myung Kwan,Kim, Jae Ik,Lee, Ye Ji,Jeon, Ju Hyun,Kim, Eunseok,Kim, Jung Ho,Kim, Young Il Korean AcupunctureMoxibustion Medicine Society 2018 Korean Journal of Acupuncture Vol.35 No.3

The aim of this report is to describe improved symptom changes in eye movement disorders and dizziness of a patient with Miller Fisher syndrome after receiving combined Korean medicine treatment (CKMT). A 24-year-old male was diagnosed with MFS accompanied by eye movement disorder, diplopia, and dizziness. For 6 weeks, the patient received acupuncture, electro-acupuncture, pharmacopuncture, herbal medicine, and physical therapy treatment. Visual analogue scale were checked and other outcomes (the range of eye movement, the distance that diplopia appears, diplopia questionnaire) were measured. Following CKMT, the movement of both eyes improved in both the horizontal and vertical direction. Also for diplopia and dizziness, there was a decrease in the visual analogue scale and the distance that diplopia appeared. The present case report suggests that CKMT may have a role in treating eye movement disorders and dizziness in patient diagnosed with MFS.
