이석수,Lee, Seok-Su 한국자연공원협회 1986 한국자연공원 Vol.33 No.-
본고는 지난 3월 6일부터 10일동안 자연공원법 개정을 위한 자료수집 및 연구조사 작업의 일환으로 일본환경청 자연보호국을 비롯 자연공원관계부처와 일본 국립공원협회, 미화관리재단 등 20여 기관을 순방한 바 있었던 이석수 건설부 자연공원 과장이 국립공원지의 발전과 회원제위 뿐만 아니라 특별회원 (관련 공무원.관리요원)의 참고자료가 되도록 자연공원법개정을 앞둔 바쁜 일정 속에서 소견을 첨가해서 초록해 준 것이다.
A Reemergence of Geopolitics in East Asia: Development, Determinants, and Implications
이석수 국방대학교 국가안전보장문제연구소 2016 The Korean Journal of Security Affairs Vol.21 No.1
The new trends of geopolitics indicate growing tension and destabilization of East Asia with the potential for accommodation. It is proved that security configuration is attributed to redistribution of power, interdependence, roles of middle powers, a growing number of non-state actors, ideational factors, and broadening and deepening of the security concept. Redistribution of power plays a decisive role in shaping regional geopolitics. Other factors are associated with cooperation and conflict as well. However, their impacts on geopolitics seem to be limited at best. The security environment in East Asia appears uncertain and complex. At this moment, confrontation appears to prevail over accommodation in a geostrategic sense. Major power rivalry is the case in point. In the meantime, East Asia has accumulated experience of regional cooperation especially since the end of the Cold War. All in all, a new strategic confrontation poses challenges to the regional security, while amassed practice of cooperation provides an opportunity to the region. To reduce lingering bilateral animosity and accrued confrontation, both bilateral and multilateral efforts should be made. One of the recommendations is that the rising middle powers of India, South Korea, Indonesia, and Australia should make contributions to enhancing multilateral cooperation.
Comparison of the Long-Term Results of R3 and R4 Sympathicotomy for Palmar Hyperhidrosis

Background: Video-assisted thoracoscopic sympathicotomy has been determined to be the best way to treat palmar hyperhidrosis. However, satisfaction with the surgical outcomes decreases with the onset of compensatory hyperhidrosis (CH) over time. The ideal level of sympathicotomy is controversial. Therefore, we compared the long-term results of R3 and R4 sympathicotomy. Methods: We retrospectively reviewed 186 patients who underwent video-assisted thoracoscopic sympathicotomy between September 2001 and September 2015. We analyzed the long-term results with respect to hand sweating and CH, and the overall satisfaction in 186 patients. Results: With respect to hand sweating, significantly more patients complained of overly dry hands in the R3 group (25% versus 3.7%, p<0.001) and of mildly wet hands in the R4 group (2.9% versus 13.4%, p=0.007). There was a significantly increased occurrence rate of CH in the R3 group (97.1% versus 65.9%, p< 0.001). The most frequent site of CH was the trunk area. The overall satisfaction was higher in the R4 group, but without significance (75% versus 85.4%, p=0.082). Significantly more patients reported being very satisfied in the R4 group (5.8% versus 22.0%, p=0.001). Conclusion: T he R 4 group h ad a h igher rate of satisfaction than the R3 group with respect to hand sweating. CH and hand dryness were significantly less common in the R4 group than in the R3 group. The lower occurrence of hand dryness and CH resulted in a higher satisfaction rate in the R4 group.

Aortic dilatation and dissection are severe complications during pregnancy that can be fatal to both the mother and the fetus. The risks of these complications are especially high in pregnant patients with Marfan syndrome; however, incidents of descending aortic dissection are very rare. This case report involves a successful Bentall procedure for and recovery from a rare aortic dissection in a pregnant Marfan patient who developed acute type II aortic dissection with severe aortic regurgitation and chronic descending aortic dissection immediately after Cesarean section. Regular follow-up will be needed to monitor the descending aortic dissection.
