  • 대한민국의 주요 하천인 한강, 금강, 낙동강, 영산강에서 2009년 11월부터 정부가 추진하는 4대강 살리기 사업(이후 4대강 사업)이 본격적으로 시작됐다. 정부는 기후변화 시대에 홍수와 가뭄에 대비하고 물 부족 시대에 수자원을 확보하며, 하천의 자연 생태계를 살리고 사람이 즐길 수 있는 레저 친수문화 공간을 조성하기 위해서라고 사업 목적을 내세운다. 환경시민단체와 상당수의 학자, 전문가들은 4대강 살리기 사업의 근간인 하도(강줄기)준설과 보 건설은 하천 수질 오염과 자연과 생태 환경 파괴로 끝날 뿐이라며 강하게 반대한다. 22조 2천억 원이라는 막대한 사업비가 들어가는 거대 사업의 시한을 정부는 이명박 대통령 임기 말년인 2012년으로 못 박고 있다. 2010년 지방선거와 2012년 차기 대통령 선거를 앞두고 전국 규모의 대형 토목 개발 사업을 이용한다는 의혹까지 제기되고 있다. 4대강 살리기 사업에 대한 비판과 결과에 대한 논란은 사업 기간은 물론 종료 이후에도 계속될 것으로 전망된다.

  • This study aims to examine the moderating effects of environmental friendly attitudes between perceived value and loyalty in ecotourists. A total of 210 valid questionnaires were collected from visitors to Saemangeum and Sihwaho during 7 days. The functional value, social value, and emotional value were identified as dimensions of perceived value from factor analysis. Results from regression analysis revealed that emotional value and social value positively influenced loyalty. Moreover, environmental friendly attitudes were found to moderate the relationship between loyalty and emotional and social values. The findings suggest that policy makers and practitioners consider environmental friendly attitude and perceived values in making ecotourism programs to sustain ecotourism destinations.

  • The integration of Tourism and Information Communication Technology (ICT) has been continued based on a drastic progress of ICT in the entire sectors of tourism industry. A variety of terminologies such as eTourism, Virtual Tourism, Smart Tourism have appeared during the last decades, however, tourism with Smartphones created a new paradigm has not discussed yet in tourism industry and academia. By investigating on the previous literature in the role of ICT in tourism, we have classified five major streams in the past such as end user perspective (tourist behaviour), Community, Multimedia and Web, Intelligent System, and Smart Tourism. At a result, we investigated the concept of smart tourism and extended to research on Smart Tourism Ecosystems. We suggest the concept of smart tourism ecosystems, which may create values by interacting among tourism players (tourist, distribution channel, supply channel, government, and local community). We propose the discussion of meaning of 'creating shared value' through 'Smart Tourism Ecosystems'.

  • The Namdae stream in Gangneung-si is one of the rivers where salmon stock is mainly maintained by natural spawning rather than artificial seedlings. There are structures including weir, and fish distribution and movement characteristics can be different by these structures. In this study, we investigated the distribution and behavioral characteristics of salmon by sighting survey within 12 km immediately upstream of the river mouth between October 2021 and February 2022. As a result, salmon distributed within 9 km from rivermouth. There were more salmon in the lower reaches of Doosan weir than in the upper reaches of that. The main spawning ground for salmon was between 7-9 km from rivermouth and around the lower part of Doosan weir. Salmon behaved for spawning in the gravel-bed area and undercut slope of the mainstream, such as mating, digging the riverbed, and competition among males. Salmon moved more slowly in the gravel-bed area than sand-bed area. Doosan weir hinders the spawning migration of salmon by frequent flow changes and terraced fishway. This study provides primary information to understand the ecological changes of salmon by environmental changes in the Namdae stream.

  • This study assessed the ecological and behavioral characteristics of the sika deer from April 2012 to August 2016. To obtain basic information on the behavioral patterns of the sika deer (Cervus nippon) including their annual home range, sika deer wearing GPS tracking collars were released into 1,385 locations at a different altitude around where they had been captured in Songnisan. The released individuals were studied through home range analysis. According to our observations, annual home ranges of the sika deer (n=6) is seen to be $2.24{\pm}1.50km^2$ (t=3.648, p<0.05) of MCP 95% for the entire area of home range and $0.46{\pm}0.31km^2$ (t=3.666, p<0.05)$km^2$ of FK 50% for the home range core area respectively. The annual home ranges of the sika deers by sex were $2.94km^2$ for female and $1.53km^2$ for male. This study is expected to provide basic data for habitat management and ecological study of sika deer and to contribute to the management of wild animals.

  • The purpose of this study is to identify the home range and habitat using pattern of the native species, Mauremys reevesii, and the exotic species, Trachemys scripta elegans, and to analyze the mutual competition relationship of the two species. This study was conducted at the Goldfish square pond, which is located in the upper part of the valley of Cheonggye mountain from August 2, 2010 to January 30, 2011. We used the three artificially proliferating M. reevesii and three T. scripta elegans which were inhabited in the ponds and reservoirs for monitoring study after attaching the transmitter to each of them. We measured the home range and the habitat utilization radius of three individuals of each species and the environmental factors such as temperature, humidity and soil and water temperature around the Goldfish square pond. As our results, it was analyzed that the M. reevesii and T. scripta elegans have a redundant ecological positions in various aspects such as limited sunbathing places, food resource utilization, hibernation place, etc. We also found that the relatively small M. reevesii was being pushed out of the competition by the relatively big. Further investigation of food competition and habitat utilization should be necessary for these two species for the natural habitats, their home range, food competition, and habitat utilization. The result of this study will be the basic data M. reevesii's restoration project.

  • During incubation, pelagic seabirds undergo large variations in their body mass as a result of concomitant fasting. In Procellariifomes undergoing important changes in body mass through the incubation, body mass regulation could be an important factor in behavioural decisions for changing activities during the incubation. The aim of this study was to investigate the effect of individuals' quality and incubation behaviour on their body mass regulation in Streaked Shearwaters Calonectris leucomelas breeding at Sasudo Island, in Jeju, South Korea during incubation period, June to August in 2013. In our results, we found that there was no relationship between the daily body mass loss and body size or condition of Streaked Shearwaters. However, the daily body mass loss increased significantly as the incubation bout increased. Moreover, the daily incubation bout was positively related to their body size. Consequently, although breeders' qualities were not related to their daily body mass loss during the incubation, the incubation behaviour affecting their daily body mass loss was regulated by their body size. Therefore, the body size of Streaked Shearwater breeders is one of important factors in their decisions for the incubation behaviour.

  • This study was conducted to understand the emotional and situational context where non-suicidal self-injury occurs in everyday life. Sixty adults(age 19-35) completed daily surveys assessing positive and negative emotions, stressful events, self-injury thoughts, and behaviors for two weeks. Using a total of 663 collected entries, we analyzed specific personal emotions and stressful events related to non-suicidal self-injurious thoughts and behaviors. As a result, high negative emotions, low positive emotions, and total stress event scores were significantly related to self-injury thoughts and behaviors. In the model in which both emotion and stress were inserted as predictors, the low level of positive emotion showed a significant related to non-suicidal self-injurious behavior. These results suggest that negative emotion management and overall positive emotion reinforcement are important in emotion regulation intervention for non-suicidal self-injurious patients. The meaning of this study is that it searched for risk factors of non-suicidal injury in everyday life using a short-term longitudinal method.
