도로교 내진보강 우선순위 결정을 위한 알고리즘에 관한 연구
김형규,장일영 한국구조물진단유지관리공학회 2018 한국구조물진단유지관리공학회 논문집 Vol.22 No.6
최근 경주, 포항 등 국내에서 지진으로 인한 피해가 지속적으로 발생하면서, 우리나라가 더 이상 지진의 안전지대가 아니며 이에 대한 대비가 필요함을 알게 되는 계기가 되었다. 또한 내진설계 개념 도입 이전에 건설된 교량들은 적절한 보강 대책이 마련되지 않은 상태로 남아있는 실정으로 경제성과 구조적 안전성이 고려된 내진보강이 순차적으로 이루어져야한다. 기존 교량의 내진성능 예비평가는 교량이 위치한 지역의 지진세기를 고려한 지진도와 취약도 및 영향도를 고려하여 4개의 그룹으로 내진 그룹화하고 이를 통해 내진성능 상세평가를 위한 우선순위가 결정된다. 본 연구에서는 기존의 방법과 다르게 교량의 중요도와 취약조건, 도로교의 세부사항을 기준으로 선정하여 도로교의 내진 보강 우선순위를 결정하는 보다 간편하고 객관적인 알고리즘을 제안하고 이를 실제 교량에 적용하여 적합성을 확인하였다. With the recent series of damage caused by earthquakes in Korea, such as Gyeongju and Pohang, we know that Korea is no longer a safe zone for earthquakes and that we need to be prepared for them. In addition, bridges built prior to the introduction of seismic design concepts remain without adequate seismic reinforcement measures, and earthquake reinforcement should be performed efficiently considering economic and structural safety. Preliminary assessment of seismic performance of existing bridges is divided into four seismic groups, taking into account seismicity, vulnerability and Impact, considering the magnitude of the existing bridge's seismic, and prioritization for further evaluation of seismic performance. In this study, unlike the existing anti-seismic reinforcement priority method, scores are calculated based on the seismic design criteria applied to bridges, importance coefficient of the bridge including the zone coefficient and the Importance, vulnerability index of the bridge including the soil condition and the elapsed years, detail coefficient of the bridge including the superstructure form, the span length, the width, the height, the design load, and the daily traffic volume. The calculated score items will be weighted and grouped according to the results. Using this, a simpler and more efficient algorithm was proposed to determine the priority of seismic reinforcement on a bridge.

According to the research, the Estern and Western medical literatural records about the causes and symptoms of the heart failure, the results as follows are concluded. 1. The asthma, suceptibility to fright and severe palpitation are generally revealed from the left heart failure. The causes of it are belong to the Yang and Yeum deficiency which are mainly caused by primordial energy deficiency. 2. The symtoms of asthma which are derived from left heart failure are related to the gasping that contain dyspnea, asthma due to the accumulation of phlegm and severe palpitation and related to shortness of breath due to fluid retention (水喘) that make asthma. 3. In the right heart failure, the edema which is derived from the congestion of vein, is revealed as stoppage of main channel that is mainly caused by the Yang or the Yeum deficiency. 4. The edema which is caused by the right heart failure, is mainly related to the symptoms of Yeum type edema, also it is related to the five viscera-fluid, moreover to the heart-fluid (心水), lung-fluid (肺水) and liver-fluid (肝水). 5. In heart failure, the pathologic symptoms which are derived from the stoppage of blood circulation, are phlegm-retention disease (痰飮), diffuse fluid-retention syndrom (溢飮), fluid-retention syndrome characterized by dyspnea and edema (支飮).

A new Symplocos trumpet leafminer, Coptotriche yanbarensis Kim & Yagi sp. nov., feeding on S. stellaris and S. okinawensis (Symplocaceae) is described from Okinawa Island, Japan. The new species is distin guishable from the Japanese Symplocos feeding described species, C. symplocosella Kobayashi & Hir owatari, 2016 by the forewing coloration, the shape of genitalia, and also DNA barcode.
