유성옥(Yoo, Seong-ok) 한국전략문제연구소 2020 전략연구 Vol.27 No.3
북한은 3대 세습체제의 특성으로 인해 선대(先代)의 혁명 유업을 그대로 계승하여 이를 절대적·무조건적으로 이행해 왔다. 최근 남북 간에 정상회담이 개최되고 일련의 합의서가 채택되면서 일각에서는 북한이 기존의 대남통일노선을 포기하고 남북공존과 평화통일의 길로 나오고 있다는 희망적인 관측이 대두되고 있다. 그러나 북한이 견지하고 있는 대남통일 전략의 논리적 토대와 추진 구도를 살펴보면, 북한은 전쟁을 통한 통일방도와 함께 남조선혁명으로 출현한 남한의 연공(聯共)정부와의 ‘전략적 배합’에 의해서 연방제 방식의 공산화 통일이라는 당초의 목표를 확고히 고수하고 있다. 북한은 이 같은 전략적 의도를 은폐하는 가운데 레닌의 혁명이론과 마오쩌둥의 국공(國共)합작, 베트남 공산화 과정에서 입증된 통일전선전술을 한반도 상황에 원용하여 남한 정부를 고립시키는 가운데, 사회 각 분야에서 광범위한 동조세력을 구축하고 확산시켜 왔다. 이에 북한은 대남 심리전, 지하당 구축, 젊은층을 겨냥한 주체사상 확산, 제도권 진입공작, 사이버 공작 등을 통해 남조선혁명과 전 한반도의 공산화 통일을 달성하기 위한 여건을 조성해 주력해 왔다. 향후에도 북한은 전략적 목표와 방향은 그대로 유지한 채 자신들이 처한 대내외 여건에 따라 다양한 형태의 전술적 변화를 지속해 나갈 것으로 전망된다. 이에 우리는 북한의 대남통일책략을 효율적으로 차단하는 한편, 나아가 대남전략의 원점(原點)인 북한 체제를 변화시키는 적극적인 대북전략을 전개해야 할 것이다. 북한이 우리에게 해 온 방식 그대로 북한 독재정권을 고립시키고 북한 주민과 국제적 자유·민주·양심세력을 한데 묶는 ‘대북(對北) 연합전선’을 구축해 나가야 한다. Due to the characteristics of the three hereditary succession systems, North Korea has inherited the revolutionary legacy of its predecessors and implemented it absolutely and unconditionally. With the recent summit between the two Koreas and the adoption of a series of agreements, some have raised wishful view that the North is giving up its existing unification strategy on the Korean Peninsula and is taking the path of co-existence of two Koreas and peaceful reunification. However, looking at the logical foundation and implementation structure of its unification strategy, the North has maintained its original goal of unification in the form of a federal system of communization on the Korean Peninsula by the "strategic combination" with South Korean government, which would emerge by the revolution in South Korea along with the way of unification through war. North Korea has been building and spreading a wide range of sympathizers in various sectors of South Korean society to isolate the South Korean government, using unified front tactics derived from Lenin"s theory of revolution, Mao Zedong"s national collaboration and Vietnam"s communization process. Accordingly, North Korea has created conditions for the South Korean revolution and the communization unification of the entire Korean Peninsula through psychological warfare against the South, building underground parties, spreading syringes aimed at young people, legal entry into the legal system, and cyber maneuvering. In the future, North Korea is expected to continue to make various types of tactical changes depending on its internal and external conditions while maintaining its strategic goals and directions. In response, South Korea should effectively block the North"s unification strategy against the South, while also actively carrying out strategies to change the North Korean regime, which is the origin of its strategy against the South. As North Korea has done to South Korea, it should establish “a unified front against North Korea” that isolates the North Korean dictatorial leadership from its people and binds the North Korean people with international freedom, democracy and conscience.

만성 간질환과 간세포암종 환자에서 Basic Fibroblast Growth Factor와 Vascular Endothelial Growth Factor의 혈청 농도
김창민,홍석일,이진옥,유성재,정성문,정숙향,이진오,한철주,김종광,송용환,홍영준,김유철 대한간학회 2001 Clinical and Molecular Hepatology(대한간학회지) Vol.7 No.1
Background/Aims: Angiogenesis occurs in response to tissue damage, and is of vital importance for tumor growth and metastasis. Basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF) are potent angiogenic factors, and have been suggested to be useful diagnostic markers in certain hypervascular tumors. However, little is known of serum bFGF and VEGF in patients with hepatocellular carcinoma (HCC). We attempted to measure serum bFGF and VEGF in patients with chronic liver diseases (CLD) and HCC to assess their pathogenetic role and usability as tumor markers. Methods: Serum bFGF and VEGF were measured in 8 patients with chronic hepatitis (CH), 15 patients with liver cirrhosis (LC), and 49 patients with HCC. bFGF was measured in 33, and VEGF was measured in 50, healthy blood donors. Results: Serum bFGF was 3.8±1.9, 2.0±1.4, 4.2±6.0, 17.4±30.0 pg/mL in normal control, CH, LC, HCC, respectively. The serum bFGF level was significantly increased in patients with HCC when compared withmal control or patients with CLD. No difference, however, was observed in serum VEGF levels among the four groups. The serum levels of bFGF and VEGF were not significantly different in patients with HCC according to tumor type, size and stage. Serum bFGF showed good sensitivity (90%), specificity (87%), and positive predictive value (94%) in differentiating patients with HCC from those with CLD at the cut-off value of 4.6 pg/mL. Conclusions: bFGF might play a role in the growth of HCC and its serum level might be used as a tumor marker. On the other hand, serum VEGF does not seem to be an adequate tumor marker.(Korean J Hepatol 2001;7:47-54)

간세포암 진단을 위한 세침흡인 세포학적 검사의 필요성과 안전성
이진오,김창민,김유철,이진옥,유성재,정성문,이병희,정숙향,한철주,이승숙,조경자,송용환,김기환 대한간학회 2000 Clinical and Molecular Hepatology(대한간학회지) Vol.6 No.4
Backgrounds/Aims: The fine-needle aspiration (FNA) is a useful method for diagnosis of hepatocellular carcinoma (HCC). The aims of our study are to assess diagnostic accuracy of FNA, to define proper indications of FNA for diagnosis of HCC, and to evaluate the complications of FNA. Subjects and Methods: To assess diagnostic accuracy we compared the results of preoperative FNA with postoperative pathology in 38 resected cases with primary liver cancer. To define proper indications and complications of FNA, we prospectively followed 138 patients received FNA for their liver tumors which were suspicious of primary liver tumor. Results : The sensitivity, specificity, positive and negative predictive values of FNA were 100%, 97%, 100% and 66% respectively. All patients with serum alpha-fetoprotein (AFP) level over 1000 ng/ml were having HCC on FNA result. Among 36 patients with AFP level ranged 15-1000 ng/ml and hypervascular mass on angiography, 96% were having HCC. Among 50 patients with normal AFP level and hypervascular mass on angiography, 92% were having HCC. The major complications after FNA such as hemoperitoneum, pneumothorax, and iatrogenic arterioportal shunt developed in 2%, 2%, and 7% of subjects, respectively. We did not find any case of needle-tract seeding of cancer during a mean 4.7 months of follow-up. Conclusions: Although the FNA is an accurate method for diagnosis of HCC, FNA was usually not indicated for patients with serum AFP level over 1000 ng/ml or patients with hypervascular mass on angiography when they were suspected of having primary liver cancer. Major complications were hemoperitoneum, pneumothorax and iatrogenic arterioportal shunt. Iatrogenic arterioportal shunt may influence the efficacy of subsequent transcatheter arterial embolization(Korean J Hepatol 2000;6:505-513).
