Safety climate in the research area of industrial safety begins to be influential meta-theory. With this research trend, this paper is to examine the relationship between safety climate and safety participation, and the moderating effect of age. Data were gathered from 292 manufacturing workers in construction industry. It is found that management involvement, safety education, and precaution activities have affirmative effect on safety participation, and physical job load negative effect on it. Next, education, precaution activities, and safety system were found to have interactional effects on safety participation with age.

This study was conducted to determine the effect of the climate change to the level of groundwater recharging. This research was conducted on the watershed of Bangga by using the Soil Water Balance of MockWyn-UB model. Input data compose of evapotranspiration, monthly rainfall, watershed area, canopy interception, heavy rain factor and the influence of climate change factors (rainfall and temperature). The conclusion of this study indicates that there is a decreasing trend in annual groundwater recharge observed from 1995 to 2011. The amount of groundwater recharge varied linearly with monthly rainfall and between 3% to 25% of the rainfall. This result implies that rain contributed more than groundwater recharge to runoff and evaporation and the groundwater recharge and Bangga River discharge depends largely on the rainfall. In order to increase the groundwater recharge in the study area, reforestation programmes should be intensified.

Long term streamflow regime under virtual climate change scenario was examined. Rainfall forecast simulation of the Canadian Global Coupled Model (CGCM2) of the Canadian Climate Center for modeling and analysis for the IPCC SRES B2 scenario was used for analysis. The B2 scenario envisions slower population growth (10.4 billion by 2010) with a more rapidly evolving economy and more emphasis on environmental protection. The relatively large scale of GCM hinders the accurate computation of the important streamflow characteristics such as the peak flow rate and lag time, etc. The GCM rainfall with more than 100km scale was downscaled to 2km-scale using the space-time stochastic random cascade model. The HEC-HMS was used for distributed hydrologic model which can take the grid rainfall as input data. The result illustrates that the annual variation of the total runoff and the peak flow can be much greater than rainfall variation, which means actual impact of rainfall variation for the available water resources can be much greater than the extent of the rainfall variation.

By IPCC climate change scenario, the socioeconomic actions such as the land use change are closely associated with the climate change as an up zoning action of urban development to increase green gas emission to atmosphere. Prediction of the land use change with rational quality can provide better data for understanding of the climate change in future. This study aims to predict land use change of Cheongju in future and SLEUTH model is used to anticipate with the status quo condition, in which the pattern of land use change in future follows the chronical tendency of land use change during last 25 years. From 40 years prediction since 2000 year, the area urbanized compared with 2000 year increases up to 87.8% in 2040 year. The ratios of the area urbanized from agricultural area and natural area in 2040 are decreased to 53.1% and 15.3%, respectively.

Using a sample of 180 managers in small and medium sized organizations in Chungcheong and Southern Gyeonggi Province, we proposed that official communication channel on safety issue will influence managers' safety climate, empathy (safety climate), and eventually occupational accidents. The results supported our hypotheses, showing managers concern about their employees' safety issue when the organization officially emphasize on safety issue. At the same time, it also tells that managers are emphatic on their employees regarding occupational accidents when it comes to safety climate.

Concrete changes its internal moisture distribution depending on the external environment, and changes in the condition of the material's interior over time affect the performance of the concrete. These effects are closely related to the long-term behavior and durability of concrete, and the degree of deterioration varies from climate to climate in each region. In this study, we use actual climate data from each region with distinct climates. A multi-physical analysis based on the method was conducted to predict the difference and degree of deterioration rate by climate.

In this study the GFDL GCM generated (controlled run) zonal average temperature data are evaluated by comparing their EOFs with those from observed data. Even though the correlation matrices of observed and simulated data are shown significantly different (Polyak and North, 1997b), the EOFs derived are found very similar with very high pattern correlations. This means almost all the information (second-order statistics) derived from the observed data can be reproduced by the EOFs derived from the GFDL GCM simulates. Also, the EOFs from GFDL GCM were found to have more flexible structures than those from the observed. Thus, we may conclude that the GFDL GCM can simulate the Earth's energy balance system reasonably. However, more in detail research should be focused on the effect from various forcings on climate variability, as, in some cases, the effect of external forcings could shadow the system characteristics and mislead the simulation results.

월별 기후통계량의 조화해석에 의해 생성한 일 기온 자료가 생물계절모형의 입력자료로서 적합한지 여부를 평가하여 농림업 부문 기후시나리오 응용정보 제작 상오류를 제거하기 위해 본 연구를 수행하였다. 서울관측소의 1971-2000 평년 월별 일 최고기온과 최저기온 평균값으로부터 조화해석에 의해 365일 간 기온자료를 생성하였다. 이것을 널리 검증된 온도시간 기반의 벚꽃 개화모형에 입력하여 휴면, 발아, 개화 등 주요 식물계절을 추정하였다. 같은 기간 중 실측기온자료에 의해 모형을 구동시켜 얻은 결과와 비교한 바, 연차변이를 전혀 반영하지 못하는 것은 물론, 휴면해제 25일 단축, 강제 휴면기간 57일 연장, 발아 14일 지연, 개화 13일 지연등 평균값도 크게 달라 식물계절을 크게 왜곡시키는 것으로 판단되었다. 대안으로서 확률추정기법에 의해 일기상자료를 생성하고 이를 이용하여 모형을 구동한 결과 실측결과에 비해 휴면해제 6일 단축, 강제휴면기간 10일 단축, 발아 3일 지연, 개화 2일 지연 등으로 조화해석자료 사용에 비해 크게 개선되었음을 확인하였다. 연차변이양상 역시 실측기온에 의한 모의결과와 크게 다르지 않아, 향후 이 자료를 농업부문 전자기후도 제작에 적용하면 기후변화 적응정책 수립을 실용수준에서 지원할 수 있을 것으로 보인다.

기후변화는 곤충의 밀도와 분포, 몸의 형태와 개체의 크기 등 생물학적인 형질 변화, 생식 및 유전적 특성, 그리고 멸종 등에 영향을 미칠 것으로 예상되고 있다. 기후변화의 영향을 예측하여 피해를 줄이기 위해서는 분산되어 있는 곤충 종별 기본적인 생물학적/생태학적 정보들을 종합하여 검토할 필요가 있다. 따라서 본 연구는 기후 및 환경의 변화에 대한 곤충, 특히 해충의 발생 변화 예측에 필요한 생물학적 정보를 정리하여 이를 활용한 미래 피해 예측을 위한 기초 자료를 제공하고자 수행하였다. 또한 국내외 문헌을 비교 분석하여 국내에서 기후변화 연구를 수행하는데 있어 제한 요인들을 확인하고 향후 필요한 연구소요를 제시하고자 하였다. 국내의 연구들은 단기 모니터링 자료를 이용하여 환경 요인과의 관계를 분석하는 수준에 그치고 있는 반면, 국외 연구들은 장기 모니터링 자료를 이용한 분포 변화 분석이나 기 개발된 생물 종의 파라미터를 이용한 발생 및 분포 변화 예측 그리고 곤충 군집의 구성 변화를 모니터링하는 등 다양한 내용을 주제로 기후변화의 영향을 연구하고 있었다. 결론적으로 기후변화에 대응하기 위해서는 체계적인 모니터링 기술 개발을 통해 곤충의 계절발생, 분포, 월동 특성 및 유전적 구조 변화에 대한 연구가 필수적이며, 주요 해충 및 잠재적인 해충에 대한 기후변화의 영향을 예측하기 위해 곤충 개체군 모델의 개발 역시 중요한 부분이 될 것이다.
