Based on the Job Demand-Resource (JD-R) Model, this study aimed to explore the effects of job demand and resource on Anti-Abuse Police Officers (APOs)’ turnover intention and the mediation effects of job burnout and engagement in their relationships. For the purpose, the self-report survey was conducted to APOs and the collected data was analyzed with Structural Equation Modeling (SEM). The results of the study are as follows: The paths of job demand-job burnout-turnover intention and job resource-job engagement-turnover intention were significant. Also, the mediation effects of job burnout and job engagement were all significant but the one of job engagement on the path from job demand to turnover intention. These results suggest that it is necessary to improve APOs’ work environment to prevent their high level of job burnout and to lower the turnover rate. 본 연구에서는 직무요구-자원 모형을 토대로 학대예방경찰관(APO)의 직무요구 및 직무자원이 각각 직무소진과 직무열의를 매개로 보직이동의도에 미치는 영향을 알아보고자 하였다. 이를 위해 APO 164명을 대상으로 한 설문응답을 토대로 연구모형을 구조방정식모형으로 분석하였다. 연구 결과, 최종적으로 직무요구-직무소진-보직이동의도, 직무자원-직무소진-보직이동의도의 경로에서 직무소진의 매개효과를 확인하였으며, 직무자원-직무열의-보직이동의도의 경로에서도 직무열의의 매개효과가 유의한 것을 검증하였다. 이 같은 연구결과는 APO의 직무열의를 높이고 소진을 예방하여 직무의 효과성을 높이고 보직이동의도를 낮추는 논거를 마련하여 실무적으로 유용한 정보를 제공할 것이다.

This study is designed to find an optimized forest management scheme in preparation for inclusion of the value of carbon abatement in existing forest stands. Schemes to mitigate climate change by protecting forests include reforestation, afforestation and efficient forest management to maximize carbon absorption. The rotation period is extended if the value of carbon absorption as well as the timber values are considered for the stands of pine trees and Korean pine trees. The current management scheme is also analyzed and compared with optimal solutions. The result shows that in the case of pine trees the rotation period is optimal with the current method. But the rotation period decreases and the function value (objective value) increases if the optimal scheme is applied. The reason is that late execution of second thinning brings about slow progress of volume increment and extends the rotation period. If the rotation period is extended the present value from stands is discounted more seriously. To enhance the value of stands, the current rotation should be shortened, and the thinning should be executed at a time. In the case of Korean pine trees, the current rotation period is too short, and it is not optimal even under the current management method. Under the optimal management scheme, however, the rotation period becomes shorter than the current method. This happens because the current method includes four times of silvicultural treatments, and they last until 35 years after plantation. The cost of the treatments could not be recovered until after 100 years of plantation. Hence it is necessary to reduce the frequency of cutting and the age of final cutting. The simulation results show that the rotation period becomes shorter if the discount rate increases, and it becomes longer if the price of carbon dioxide increases. It is well known that the rotation period increases if the public values are added to the stands. However, it is also possible to find an optimal management scheme by adjusting the frequency and time of silvicultural treatments. Consequently, it could not be an optimal method of forest management to apply long and flat rotation periods even if some public values are added, but it is necessary to adjust and apply various rotation periods according to treatment numbers and cutting ages of different species.
