Many companies are adopting performance measurement systems(PMS) in order to acquire competitive advantage the promote long-term growth in Coping with the rapidly changing business environment. Prior research has focused on the relation between PMS and organizational performance. However, there is limited empirical research that examines the behavioural consequences of PMS. Further, there is little empirical research that examines whether measurement diversity have direct and/or indirect effects on work performance. As such, I examine how the relation between measurement diversity and managerial performance can be explained by the intervening variables of justice and organizational citizenship behaviour. This study is summarized as follows: this study finds that measurement diversity affect managerial performance indirectly through justice and organizational citizenship behaviour.

기후변화는 자연적 요인보다는 인간의 활동으로부터 기인하는 것으로 알려진다. 지구 온난화의 영향으로 우리나라의 평균 기온은 상승하고 있으며, 강수량 또한 증가추세에 있다. 이러한 미래 기온의 상승과 강수량의 변화는 나아가 수문 순환에 영향을 미치며, 수자원의 효과적인 이용을 위하여 기후변화에 따른 수문 순환 특성을 파악하는 것은 매우 중요하다. 이에 본 연구에서는 국제 수문 프로그램의 대상 유역 중 하나로 장기간의 강우-유출 자료가 구축되어있는 청미천 유역을 대상으로, 기후변화에 따른 지표 유출량 변화를 살펴본다. 기후변화를 전망하기 위한 방법으로 인간 활동이 대기에 미치는 복사량으로 온실 가스 농도를 정의하는 시나리오인 대표농도경로(Reperentative Concentration Pathway, RCP)를 적용하였다. 기상청에서 제공되는 여러 RCP 시나리오 중 기후변화가 현재의 추세를 쫓아 상승 형태를 나타내는 RCP 8.5 시나리오와 저감 정책이 어느 정도 실현되어 형태가 안정된 RCP 4.5 시나리오 두 개를 선정하였다. 기후변화 시나리오는 근본적으로 불확실성을 포함하기 때문에, 특정 기후변화를 가정하기 보다는 특성이 대비되는 두 개 시나리오를 적용하여 기후변화의 발달 정도에 따른 유출량 변화를 살펴보고자 한다. 장기간의 수문 순환 특성을 모의하기 위하여 준 분포형 장기유출 모형인 Soil and Water Assessment Tool(SWAT)을 이용하며, SWAT에서 요구되는 방대한 양의 매개변수들은 매개변수의 최적값 산정 프로그램인 SWAT Calibration and Uncerntianty Programs (SWAT-CUP)을 통해 얻는다. 과거의 강우-유출 자료로부터 구축된 SWAT 모형에 기후변화 시나리오를 적용함으로써 기후변화 시나리오에 따른 지표유출량 변화를 살펴볼 수 있다. 구축된 SWAT 모형을 이용하여 모의를 한 결과, 두 개 시나리오 모두에서 청미천 유역의 지표유출량이 증가하는 것으로 나타났으며 RCP 4.5 시나리오보다 RCP 8.5 시나리오에서 더 많은 유출이 발생할 것으로 전망된다. 유출량의 증가와 함께 총 부유사량 또한 증가 추세에 있으며, RCP 8.5 시나리오에서 더 많은 유출이 계산된다. 이러한 유출량의 증가는 강수량, 기온, 일사량, 풍속, 습도와 같은 기후 특성의 변화가 고려된 결과로 판단된다. 기후변화에 따른 총 유사량의 증가는 범용토양 유실공식에서 강우 에너지의 증가로 인해 유출량과 동일한 양상을 띠는 것으로 판단된다.

With respect to the quantity, quality and social value of forest jobs, we have developed three major criteria and 11 indicators for evaluating decent forest jobs. The importance and weighted value of the criteria and indicators were investigated through a survey which was conducted on 50 experts involved in Governmental Forest Job Committee, academic and different groups of communities. The 35 experts responded to the survey chose the 'job creation potential' as the most important criterion, and they recognized the 'job quality' has a relatively higher importance than the 'social contribution'. The survey results showed that 'political will' and 'job security' have the highest weighted values among indicators while 'wage level' has the lowest value. The developed criteria and indicators are able to be used as a means of evaluating degree of decent forest jobs for both new and existing jobs.

Due to the recent increase in the disabled population and welfare paradigm, the government is focusing on green welfare and environmental welfare to improve the living environment of the disabled, including the enactment of basic laws and convenience promotion laws. Accordingly, green environmental welfare for the disabled is supported in policy, but there are no evaluation indicators for the green welfare space and healing environment created. Therefore, this study divided the healing environment into physical, psychological, and social aspects, and conducted research using expert FGI to present evaluation indicators that can determine whether spatial roles and functions are appropriate. As a result of the study, the final 51 healing environment evaluation items were derived from 26 physical aspects evaluation items, 14 psychological aspects evaluation items, and 11 social aspects evaluation items. Evaluation indicators derived from this study can be used to evaluate the healing environment created in disabled residential facilities, and can be used as basic data in the planning stage of the healing environment to be created in the future.

Changes in megatrends occurring within the spatial range of the production process can be critical factors that affect the performance of unit projects in construction industry, one of the representative order industries. Although changes in the megatrend are a prerequisite for successful performance achievement, previous studies suggested methods for performance measurement and management within the production process as major results. Accordingly, this study analyzed the megatrend related to domestic construction projects and presented critical impact factors(CIFs) that can be affect a project's performance. CIFs were set by combining keywords derived by reviewing major contents of related laws and policies and future strategy reports, and the importance of each indicator was quantitatively analyzed using analytic hierarchy process(AHP). It is expected that the findings of this study can provide meaningful basic data that the various stakeholders in a construction project can refer to when establishing the strategies to achieve successful performance.

Keen attention has been directed at "smart tourism cities" due to its role of solving urban problems arising from modern tourism development. However, some local governments are making huge investments in developing uniform tourism apps without specific directions or guidelines for the transformation of smart tourism cities. Accordingly, this study aims to develop a standardized and objective smart tourism competitiveness index and evaluate the competitiveness rankings of various cities around the world. The index comprises the five subindices of attractiveness, accessibility, digitalization readiness, sustainability, and co-partnership. The analysis results have shown that Singapore is the most competitive smart tourism city, followed by Amsterdam, New York City, Seoul and Barcelona, with Ho Chi Minh and Bangkok being relegated to the bottom of competitiveness rankings. We expect that this index can be employed as a global standard for continuously and systematically monitoring smart tourism city-related projects in the future.
