This study formulates a development strategy for Gwangyang port through the analysis of its competition with other major Northeast Asian ports. A revised BCG matrix is applied to estimate the change in competition between the major ports in Northeast Asia and the Lotka-Volterra model is used for the competitor analysis. The growing competitive power and influence of Chinese ports, continued competitive advantage of Busan port, diminishing competitiveness of Gwangyang and Incheon ports, and disappearing competitive position of Japanese ports in Northeast Asia are all confirmed. In addition, according to the relationship between Gwangyang port and other major Northeast Asian ports from 2007 to 2014, Gwangyang port has changed to a predatory from a win/win relation with Busan port and has maintained its predatory relationship with Hong Kong port in terms of transshipment cargoes. Moreover, Gwangyang port has formed predatory relationships with Shanghai and Ningbo ports, a pure competitive relation with Tianjin port, and a win/win relation with Qingdao and Dalian ports. Overall, predatory relationships between Gwangyang port and other Northeast Asia ports increased from 2007 to 2014. The counterstrategies for Gwangyang port to address this situation include establishing cooperative relations and continuing the win/win relationships with cooperative ports.

수자원개발과 관리 측면에서 하천에서 흐르는 유량을 정확히 산정하는 것은 이수와 치수 두 측면에서 모두 매우 중요한 문제이다. 과거의 유량측정성과를 이용하여 수위-유량 관계 곡선식을 구하면, 현재 관측된 수위만으로도 유량을 간단히 산정할 수 있기 때문에 유량 산정에서 있어서, 수위-유량 관계 곡선식을 사용하는 것이 일반적이며, 따라서 수위-유량 관계식의 신뢰도에 의해 유량 산정의 정확성이 좌우되는 것이 사실이다. 과거 일반적인 단일 수위-유량 곡선의 적용으로는 유량추정에 높은 불확실성이 존재할 수 있음이 확인되어, 하천의 단면변화, 식생변화, 유사이동, 비정상류 등 영향인자를 파악하고 수위-유량 관계의 동적 변화를 추정하는 기술의 고도화가 다양하게 시도되고 있다. 기존 연구에서는 하천의 수위에 따른 단면 변화율 차이 등을 가정하고 수위구간을 구분 다른 수위-유량 관계식으로 추정하는 방안이 제안되거나, 부정류, 하상경사, 그리고 조도계수 변화에 따른 수위-유량 관계 변화 가정하고 특정 조건에 따라서 수위-유량 관계가 변화하는 특성이 연구되었다. 하지만, 검토한 바에 따르면 기존 연구에서는 대부분 수위 관측 지점에 한하여 단면 및 하상특성 등의 영향을 고려하였으며, 수km 떨어진 원거리 하류 범위에서의 하상 등 동적 변화로 인한 상류 지점의 수위-유량 관계의 영향에 대해서는 정량적 분석이 미진한 것으로 파악되었다. 따라서, 본 연구에서는 이러한 조건에 따른 복잡한 동적 수위-유량 관계를 분석하기 위한 기계학습 기반 데이터 분석기술의 활용 방안을 검토하고, 시범적으로 금강 세종보가 가동중이였던 2017년 관측된 보상류 5km 지점의 수위와 유량 데이터 분석에 적용하였다. 분석 결과 하류 5km 범위에서의 하상변화는 즉각적으로 상류의 수위-유량 관계를 변화시키는 것으로 확인되었다. 이러한 결과로부터 하류에서의 준설, 퇴적, 교량 및 보건설, 가동보 운영 등이 있을 경우 수km 떨어진 상류에서 수위-유량 관계는 크게 변화함을 예상할 수 있으며, 따라서 유량산정의 신뢰도 제고를 위해서는 본 연구에서 제안된 방안과 같이 동적 수위-유량 관계를 추정하는 기술이 점차 확대 적용되어야 할 것으로 판단된다.

This study aims to confirm the effect of different types of interpersonal stress factors of private security officers that are prevalent in the course of carrying out their duties on job satisfaction and turnover intention. The authors have examined 175 of the 200 survey questionnaires distributed to the employees of private security firms located in Seoul and Gyeonggi Province in December 2012. The result of the analysis indicates that the primary source of stress in the private security officers is the interaction with customers, followed by the relationships with colleagues and superior officers. In addition, colleague-related stress is found to be the only interpersonal stress factor with a statistically significant negative effect on job satisfaction, while both the stress from the relationships with colleagues and superior officers are positively correlated with turnover intention. Furthermore, the colleague-related stress is revealed to mediate job satisfaction which has a statistically significant effect on turnover intention. The result from the study emphasizes the importance of managing the interpersonal stress in private security officers and confirms the necessity of effectively handling the stressful situations in the relationships with colleagues. Moreover, in order to raise job satisfaction levels and minimize turnover which is vital in accomplishing the goal of each organization, causal factors of the stress need to be recognized and handled appropriately. This will provide the future research with an insight into the effective interpersonal stress management and examining other factors of job satisfaction and turnover intention of private security officers.

It has been well known and empirically supported that many persons with psychiatric disabilities experience recovery in the community. The sense of recovery is experienced while they recognize and manage mental illness and cope with everyday life utilizing personal and social resources. In order to explore ways in which the sense of recovery is enhanced, this study investigated the structure of relationships among the mental health state, optimism, positive emotions, quantity and quality of the social relationships, coping, and recovery of 460 persons with psychiatric disabilities through structural equation modeling. Of findings, first, in the results of path estimates of measurement and theoretical model, especially optimism and positive emotions demonstrated significant effects on the social relationship, coping, and the recovery, while, by contraries, positive emotions showed no significant direct effects on coping, neither the social relationships did on the recovery. Second, on the recovery optimism and positive emotions had direct effects, while quantity and quality of the social relationships had only indirect effects. It is particularly noted that positive emotions showed stronger effects on the recovery than optimism, and also had direct and indirect effects on the social relationships. Finally, partial mediating effects of coping were found between optimism and the recovery, between quality of the social relationships and recovery, and between quantity and quality of the social relationships; another partial mediating effects of quality of social relationships between quantity of social relationships and coping, and between positive emotions and coping; and the last same effects of quantity of the social relationships between positive emotions and coping. According to these results, discussions and implications for social work practice and practice research were suggested regarding the differential effects of positive cognitions and emotions on the recovery and different mechanisms of the quality and quantity of the social relationships, and the relationships among the resources, coping, and the recovery of persons with psychiatric disabilities.
