미중패권경쟁에서 아세안을 통한 한국의 경제개발 전략에 관한 연구
유근환(Keun Hwan Yoo),양혜원(Hye Won Yang) 대구과학대학교 국방안보연구소 2023 사회융합연구 Vol.7 No.6
미국과 중국의 무역 경쟁은 관련 동맹국에게도 영향을 미칠 정도로 치열하다. 반도체는 첨단산업의 쌀이라고 불릴 정도로 최첨단 기술에서 중요한 역할을 하며 자동차, 휴대폰, 디스플레이 등에 반드시 들어가기 때문에 산업에서도 반드시 안전한 공급망이 확보될 필요가 있다. 본 연구는 미중패권경쟁 속에서 한국의 국익을 높이기 위하여 아세안을 활용한 경제외교를 강화하는 것이 필요하다는 것에 주목하여 연구를 하였다. 아세안 국가들은 헤징(Hedging)전략을 통하여 실리를 추구한다. 우크라이나 전쟁이 계속되고 이스라엘과 하마스가 이끄는 팔레스타인 급진 무장 단체가 전쟁을 치르면서 국제적으로 안보 위기가 나타나고 아세안 국가들은 전략적으로 협력하는 것이 필요하다는 데 의견을 모으고 있다. 미국은 아시아로의 회귀((Pivot to Asia)를 강조하면서 관계를 개선하려는 노력을 꾸준하게 하였다. 중국은 중국은 동남아시아 지역에서 중국의 영향력을 확보하는 것이 필요하다고 보고 아세안에 적극 참여하고 있다. 한국이 전략적으로 이러한 어려운 상황을 타개하기 위해서는 아세안 국가들과의 협력을 강화하고 경제외교를 추진하여 실리적인 이익을 확보하여야 한다. 한국은 지리적으로 아세안 국가들과 가까운 편에 속하기 때문에 수출 다변화와 수입 다변화의 측면에서도 아세안을 통하여 협력하는 것이 필요하다. 한국은 아세안과의 경제외교를 강화하여 향후 아세안 국가들이 빠르게 경제 성장을 하였을 때 상생하는 관계가 되도록 전략적인 노력을 하여야 한다. 한국은 베트남, 라오스, 태국, 캄보디아, 미얀마, 필리핀, 브루나이, 말레이시아, 싱가포르, 인도네시아와 협력하고 경제외교를 강화하여 한국의 국익을 확보하여야 한다. The trade competition between the United States and China is fierce enough to affect relevant allies. Semiconductors play an important role in cutting-edge technology, so much so that they are called the rice of the high-tech industry. Since they are essential for automobiles, mobile phones, displays, etc., there is a need to ensure a safe supply chain in the industry. This study focused on the need to strengthen economic diplomacy using ASEAN to enhance Korea's national interests amid the US-China hegemony competition. ASEAN countries pursue practical benefits through hedging strategies. As the war in Ukraine continues and Israel and the Palestinian radical armed group led by Hamas are at war, an international security crisis is emerging, and ASEAN countries are converging on the need for strategic cooperation. The United States has consistently made efforts to improve relations, emphasizing a pivot to Asia. China believes that it is necessary to secure Chinese influence in the Southeast Asian region and is actively participating in ASEAN. Korea In order to strategically overcome this difficult situation, we must strengthen cooperation with ASEAN countries and promote economic diplomacy to secure practical benefits. Korea should strengthen economic diplomacy with ASEAN and make strategic efforts to create a win-win relationship when ASEAN countries achieve rapid economic growth in the future. Korea should secure its national interests by cooperating with Vietnam, Laos, Thailand, Cambodia, Myanmar, the Philippines, Brunei, Malaysia, Singapore, and Indonesia and strengthening economic diplomacy.
Microstructural characteristics and film properties of diamond-like carbon coatings grown by PECVD
Won Jae Yang,Koichi Niihara,Keun Ho Auh 한양대학교 세라믹연구소 2004 Journal of Ceramic Processing Research Vol.5 No.3
Diamond-like carbon (DLC) films were deposited by plasma decomposition of CH4/H2 gas mixtures in a RF glow discharge reactor. The chemical structure of diamond-like carbon films deposited at different bias voltages and CH4 flow contents was investigated by Fourier Transform Infrared (FT-IR) and Raman spectroscopy. An indirect evaluation on the sp3-bonded carbon in the DLC films was made based on the structural information on the sp2-bonded carbon obtained from Raman measurements. The mechanical properties of DLC films deposited at different CH4 flow contents are discussed in terms of Raman parameters such as the position, width and integrated intensities of Raman D and G peaks. The friction coefficient of DLC films was obtained and their frictional behavior was investigated.

<P>Porcine epidemic diarrhea virus (PEDV) infections have resulted in a severe economic loss in the swine industry in many countries due to no effective treatment approach. Fifteen oleanane triterpenes (<B>1</B>–<B>15</B>), including nine new ones (<B>1</B>–<B>4</B> and <B>10</B>–<B>14</B>), were isolated from the flowers of <I>Camellia japonica</I>, and their molecular structures were determined by extensive spectroscopic methods. These compounds were evaluated for their antiviral activity against PEDV replication, and the structure–activity relationships (SARs) were discussed. Compounds <B>6</B>, <B>9</B>, <B>11</B>, and <B>13</B> showed most potent inhibitory effects on PEDV replication. They were found to inhibit PEDV genes encoding GP6 nucleocapsid, GP2 spike, and GP5 membrane protein synthesis based on RT-PCR data. Western blot analysis also demonstrated their inhibitory effects on PEDV GP6 nucleocapsid and GP2 spike protein synthesis during viral replication. The present study suggested the potential of compounds <B>6</B>, <B>9</B>, <B>11</B>, and <B>13</B> as promising scaffolds for treating PEDV infection via inhibiting viral replication.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jmcmar/2015/jmcmar.2015.58.issue-3/jm501567f/production/images/medium/jm-2014-01567f_0006.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/jm501567f'>ACS Electronic Supporting Info</A></P>

<P>Twenty-four metabolites, including seven new compounds (1-7), were isolated from the dried fruits of Psoralea corylifolia. On the basis of combined spectroscopic and chemical analysis, the new compounds were determined to be six flavonoids (1-6) and a meroterpenoid (7). The absolute configurations of the natural products obtained, including the previously undetermined 16 and 17, were assigned by several methods, such as NOE spectroscopy, optical rotation, and CD spectroscopy. Several of these compounds exhibited moderate inhibitory activity toward Staphylococcus mutans-derived SrtA (2, 6, and 16) and significant stimulation of SIRT1 activity (2, 3, and 15).</P>

The effect of exo-polymer from Ganoderma lucidum on the swimming endurance capacity of mice was investigated. The administration of the exo-polymer (100 ㎎/㎏ body weight) increased the swimming endurance capacity of mice by about 10 min and reduced the muscle and liver glycogen exhaustion by 18.5% and 67.2%, respectively. A substantial decrease in serum lactate accumulation (50.7%) was also achieved under the influence of the exo-polymer. The exo-polymer was determined to be a glycoprotein with a molecular weight of 780 kDa and found to contain 82.8% carbohydrate and 17.2% protein.
