Backgrounds/Aims: Anatomical resection has superior oncologic outcomes over non-anatomical resection in hepatocellular carcinoma, and left lateral sectionectomy is the simplest and easiest perform anatomical resection procedure among liver resections. The purpose of this study was to find out the safety and feasibility of pure laparoscopic left lateral sectionectomy (PLLLS) for hepatocellular carcinoma. Methods: Patients who underwent left lateral sectionectomy at a tertiary referral hospital, from August 2007 to April 2019 were enrolled in this retrospective study. After matching the 1 : 3 propensity score, 17 open and 51 pure laparoscopic cases were selected out of 102 cases of total left lateral resection for hepatocellular carcinoma. The group was analyzed in terms of patient demographics, preoperative data, and postoperative outcomes. Results: During the study period, there was no open conversion case. The mean operative time and complication were not statistically significant different between the two groups. There was no statistically significant difference in disease-free survival and overall survival had no statistical between the two groups. There were no mortality cases, and postoperative hospital stay was significantly shorter in the PLLLS group than in the open left lateral sectionectomy (OLLS) group. Conclusions: The oncologic outcomes and complication rate were the same in the PLLLS and OLLS groups. However, the hospital stay was shorter in the PLLLS group than in the OLLS group. The present study findings demonstrate that the PLLLS is a safe and feasible procedure for hepatocellular carcinoma.

부산항 컨테이너부두에 대형 컨테이너선의 안전접안조종을 위한 연구

이 연구의 목적은 부산항에 입항하는 대형 컨테이너 선박의 안전 접안 조종을 위한 한계풍속을 설정하는데 있다. 계산결과, 정상풍속 13.5m/sec 이하의 바람에서는 예선 4500H.P.의 Z. peller 2척을 이용하여 안전 접안 조선하는데 큰 위험이 없음을 알았다. 그러나 돌풍율 25%를 포함한 강풍 16.9m/sec 이상의 기상상태에서는 선박조종이 위험하게 됨을 알았고, 돌풍율을 포함하여 풍속이 16.9m/sec 에 달하는 강풍 하에서 대형 컨테이너 선박을 부득이 접안 조종할 때는 4500 H.P. Z. peller 3 척으로 조선보조를 받아야 함을 알았다. In this paper, the authors calculated maneuvering motions of a large container vessel approaching to the newly built container piers to get alongside to her berth in Busan harbour. The motion calculations were done by using fixed coordinate system and the object of the calculations is to check the maneuvering motions are safe or not for berthing the large vessel to her berth. The result of calculations manifested that a large container vessel can get alongside to the piers without any difficulty under normal weather conditions by using 2 Z. Peller tug boats of 4500 H.P. each and also these demonstrated it is difficult to conduct and get her alongside to the piers under rough weather conditions of wind force 16.9m/sec or more. Under rough weather conditions of 6 by Beaufort scale the average wind velocity is about 13.5m and if we add 25% increase of the normal velocity to it, the wind will becomes a gust of 16.9m/sec. So it is advisable to avoid conducting a large container vessel to the pier under the rough weather conditions of 6 or more by Beaufort scale. Also, it is better to use 3 Z. peller tug boats of 4500 H.P. each under the above mentioned rough weather in a case of unavoidable circumstances.

본 연구는 21세기 기후변화에 대한 적응전략을 해수면 상승 관점에서 검토하였다. 해수면 상승에 취약한 것으로 알려진 연안역에 대한 적응책을 고려하는 경우 적응이 필요한 장소, 적응방법, 적응시기에 대한 검토가 필요하다. 연안역에 대한 적응 능력 평가는 영향 및 적응 잠재력에 대한 이해를 필요로 한다. 해수면 상승에 대한 적응방법에는 관리적 이주, 순응, 방어가 있으며, 이들의 적용에는 취약지대 토지이용 상황, 취약성 정도, 경제성 분석 등의 검토를 통한 대응 방안의 조합이 요구된다. 적응시기에 대하여는 예측적 적응과 반응적 적응으로 구분할 수가 있으며, 이들을 함께 고려하는 것이 효과적이다. 기후변화 대응은 과학적 불확실성 하에서 이루어지는 과정으로 대응정책 결정은 정보와 인식 구축, 계획 및 정책 구상, 실행, 모니터링 및 평가의 단계로 이루어져야 한다. We review the adaptation strategies of the 21st climate change in an application to sea level rise. For the development of appropriate adaptation strategies on the coast vulnerable to the sea level rise, we have to consider the issues such as where to adapt, how to adapt, and when to adapt. The coastal target needed adaptation can be found by the evaluation of adaptive capacity of the coastal zone which requires the understanding of impacts and adaptive potential of the natural and socioeconomic systems in the coastal zone. Planned adaptation options to sea level rise can be classified into three generic approaches as managed retreat, accommodation, and protection In practice, the implementation of the options requires the analysis of land use, degree of vulnerability, cost and benefit, etc, and may be combination of the options rather than one approach. In terms of the response timing, the adaptation can be grouped as anticipatory and reactive ones. Generally it is more effective to consider both anticipatory and reactive adaptations at the same time for the impacts of future sea level rise. Due to the scientific uncertainty of climate change issues including sea level rise, the adaptation processes have to be designed to deal with a series of processes such as information md awareness establishment, planning and design implementation, and monitoring and evaluation in continuity and long-term period.
