SCHUETT;  Kyu-Won SIM 收藏  |  浏览/下载：123/0  |  提交时间：2017/12/07 ThIs Paper ExamIned VIsiTors To Bukhansan NatiOnal Park In Korea Based On First-time And Repeat vIsitatiOn. Bukhansan NatiOnal Park Is Korea's Most Heavily vIsited NatiOnal Park With Annual vIsitatiOn Of Six milliOn VIsiTors In 2015. Data Used In ThIs Article Were Collected On-site In The Park In 2007 And 2013 By The Korea NatiOnal Park Service (Knps). The Study Variables Included Socio-demographics  Travel Behavior  Motivation  And Satisfaction With Park Attributes  Services And Facilities. Data Were Analyzed By Each Study Year For First-time And Repeat Visitors. Results Showed Significant Differences For Both First-time And Repeat Visitors.On Several Socio-demographic  Travel Behavior  And Motivation Variables Within Each Study Year. For Satisfaction With Park Attributes  Facilities And Services  First-time VisiTors Were Significantly Different From Repeat VisiTors On Seven Variables For Both Years. implicatiOns Are Given Regarding Programs And Services To Improve visiTor satisfactiOn And Sustain The Natural  Cultural And HisTorical Resources At Bukhansan nAtional Park And Other nAtional Parks In Korea. Future Research Suggestions Are Provided To Learn More About visiTor Characteristics  StAndards Of Quality And Preferences In The National Parks.   Quantitative analysis of COLREG rules and seamanship for autonomous collision avoidance at open sea 期刊论文 Ocean Engineering, 2017, 卷号: 140, 页码: 281-291 作者:  He, Yixiong;  Jin, Yi;  Huang, Liwen;  Xiong, Yong;  Chen, Pengfei 收藏  |  浏览/下载：5/0  |  提交时间：2019/12/04 ACA  automatic collision avoidance  CA  collision avoidance  COLREG  International Regulations for Preventing Collisions at Sea 1972  CPA  closest point of approach  CR  risk of collision  CS  close-quarters situation  DCPA  distance to the closest point of approach  FTCS  first time-in-point of close-quarters situation  FTID  first time-in-point of immediate danger  ID  immediate danger  MMG  mathematical modeling group  OS  own ship  PCR  potential risk of collision  RPM  Revolutions Per Minute  SD  ship domain  TCPA  time to the closest point of approach  TCS  time to close-quarters situation  TID  time to immediate danger  TS  target ship  Quantitative analysis  COLREG rules and Seamanship  Modeling  Navigation  Autonomous collision avoidance   Structural time-dependent reliability assessment of the vibration active control system with unknown-but-bounded uncertainties 期刊论文 STRUCTURAL CONTROL & HEALTH MONITORING, 2017, 卷号: 24 作者:  Wang, Lei;  Wang, Xiaojun;  Li, Yunlong;  Lin, Guiping;  Qiu, Zhiping 收藏  |  浏览/下载：4/0  |  提交时间：2019/12/30 active control system for structural vibration  interval process model  the first-passage theory  time-dependent reliability  unknown-but-bounded uncertainties
