  • When a weapon system is developed, climate elements such as temperature, rainfall, and so on have an effect on development costs and a developing period. Therefore, effects of environment and climate must be examined throughly before the design of weapon systems and be applied to their developments. And so, operational and storage requirements for weapon systems are determined and are applied to related tests through analyzing not only environmental factors such as vibration, shock, and so on, but also climate factors. In this paper, the distribution and the frequency of occurrence of rainfall were analyzed and were suggested as a good guide to determine standards of tests for weapon systems when it's raining.

  • The purpose of this paper is to study the effectiveness of a green roof by simple mathematical model. The developed model simulates a green roof during the summer. The results explain and support the claims in the literature such that effectiveness of a green roof depends on the climate condition, and on the insulation condition of the roof. If insolation can not be reduced more than 60% by the shading effects of a green roof, more active measures than green roof seem necessary. The analysis tools like presented in the paper is necessary especially to consider climate effect, to design, and also to test green roof.

  • The surface changes due to urban expansion and the increase of artificial heat releases have brought significant climate changes such as heat island phenomenon in urban area. Furthermore, these changes also have brought serious problems such as air temperature increase, wind changes, and air pollution in urban area. Comprehensive analytical technologies considering various effects are required to analyse complicated mechanism of climate changes, and review the efficient measures. In this research, the effect of the urban expansion in Tokyo and Bangkok area on urban environment will be discussed. By using CFD, urban development and the mechanism of global warming and wind change are studied in those two cities. As a result of numerical research, the surface changes of city could bring the environmental changes in urban area.

  • According to the advancement of computer and simulation method, it becomes possible to predict indoor climate precisely by using CFD simulation coupled with heat conduction, convection, and radiation. However, predicting the indoor climate is generally conducted by using a simplified CFD coupled simulation method since it takes quite long time to use a general CFD simulation method. In this study, a simplified CFD coupled simulation was conducted in order to find out the effect of natural ventilation by wind-driven in atrium. As a result of calculation, it was clarified that the natural ventilation driven by temperature difference was not enough to remove the accumulated heat of upper zone and the natural ventilation by wind-driven was needed. Finally, it is required to decide the window direction and size based on correct indoor climate prediction method for the effective use of natural ventilation by wind-driven.

  • Ring width chronologies of blue pine (pinus wallichiana) from two mesic sites, Kanasar(2, 400 m) and Gangotri(3, 000 m), in the western Himalayan region. India were developed to understand tree growth-climate relationship and its applicability in proxy climate studies. The resoponse function analyses of the two chronologies show that the site conditions play an important role in modulating the effect of climatic variables on tree growth. Winter temperature, prior to the growth year, has been found to play positive influence on blue pine growth at both sites. Summer temperature also has very similar response except for June and August. June temperature has negative influence at the lower in contrary to at the higher site. Low August temperature favors tree growth to precipitation has been found to vary which could be due to different precipitation regime at the two sites. Winter precipitation is important for tree growth at the higher, whereas summer at the lower sits. The present study suggests that the tree ring materials of blue pine from the temperate Himalayan regions could be used to develop chronologies for the reconstruction of seasonal climatic variables.

  • The present study was conducted to determine the effects of two types of housing systems and early age feed restriction on stress and fear reactions, and performance in broiler chickens raised in a hot, humid tropical climate. On day 1, chicks were housed either in windowless environmentally controlled chambers (temperature was set at 32$^{\circ}C$ on day 1 and gradually reduced to 23$^{\circ}C$ by day 21) or in conventional open-sided houses (OH) with cyclic temperatures (minimum, 24$^{\circ}C$; maximum, 34$^{\circ}C$). An equal number of chicks from each housing system was subjected to either ad libitum feeding (AL) or 60% feed restriction on day 4, 5 and 6 (FR). The CH birds showed greater weight gain, higher feed consumption and better feed conversion ratios (FCR) than their OH counterparts. Feeding regimen had negligible effect on overall performance. Neither housing nor feeding regimen had a significant (p<0.05) effect on mortality rate. Although the CH birds were less stressed, as measured by plasma corticosterone concentration (CORT), than those of OH, the former showed longer TI duration suggesting higher magnitude of underlying fearfulness. A significant (p<0.05) effect of housing on heterophil/lymphocyte ratios was only noted among the AL birds where the CH birds had higher values than OH. Collectively, these results suggest that although OH birds had poorer performance and higher level of stress than CH, the former were less fearful. Although FR had negligible effect on growth performance, the regimen alleviated both stress and fear reactions in broilers.

  • The purpose of this study was to investigate the effects of safety culture on the safety awareness and safety behaviors of manufacturing workers, and to suggest ways for manufacturing workers to understand the safety culture and improve safety awareness and safety behavior. In order to verify this, data were collected from 282 research subjects for 1 month from August 1 to 31, 2018, using the manufacturing workers in the Seoul and Gyeonggi area as a population. The results of the study are as follows. First, the safety culture (safety climate, safety procedures) has a positive effect on the safety awareness (recognition of importance, interest and participation inducement) of the manufacturing workers. Second, the safety culture (safety climate, safety procedures) has a positive effect on the safety behavior (safety planning, safety check) of manufacturing workers. Third, safety awareness (recognition of importance, interest and inducement of participation) has a positive influence on the safety behavior (safety planning, safety check) of manufacturing workers. Fourth, the safety awareness (recognition of importance, interest and inducement of participation) appears to have a partial mediating effect in relation to safety culture (safety climate, safety procedure) and safety behavior (safety planning, safety check) of manufacturing workers. The implication of this study is that although the industrial accidents have occurred in the manufacturing industry in recent years, the studies on the workers in the manufacturing industry are insufficient. However, this study is meaningful that it has suggested ways for manufacturing workers to understand the safety culture and improve the safety awareness and safety behavior by analyzing the effects of safety culture on safety awareness and safety behavior of manufacturing workers.

  • 우리나라 남부해안기후의 특성과 수온과의 관계를 알아보기 위하여 해안지방인 부산, 여수, 목포를 준표준 내륙지방으로 광주와 대구, 인근 해양의 가덕도, 소리도, 홍도의 수온을 선정하여 20년 간(1960~1979)의 관측자료로서 기온, 습도, 강수량을 조사 분석한 결과는 다음과 같다. 1) 해안지방(부산, 여수, 목포)은 해양의 영향으로 내륙지방(대구, 광주)보다 기온의 연교차가 적고 기온이 수온보다 높을 때는 내륙지방이 해안지방의 기온보다 높고, 수온이 기온보다 높을 때는 내륙지방이 해안지방보다 낮다. 2) 수온과 기온의 차에 따라서 내륙지방과 해안지방의 기온차가 결정되며(상관계수 0.9이상) 그 양적 예측도 상관관계식을 활용함으로써 가능하다고 생각된다. 3) 해안지방과 내륙지방의 습도의 차이도 기온의 경우와 비슷하게 나타났으나 목포는 지형적인 영향으로 다른 해안지방과 다르게 나타났다. 4) 수온과 기온의 차이에 따라서 해안지방과 내륙지방의 습도의 차이가 결정된다(상관계수 0.9이상, 목포제외), 그러므로 그 양적 해석도 가능하다. 5) 남해안지방의 강수량은 내륙지방과 그 차이가 뚜렷하게 나타나지는 않았다.

  • In this paper, we described the statistical modeling of crop yields using satellite images, climatic datasets, soil property maps, and fertilizer data for the Midwestern United States during 2001-2012. Satellite images were obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS), and climatic datasets were provided by the Parameter-elevation Regressions on Independent Slopes Model (PRISM) Climate Group. Soil property maps were derived from the Harmonized World Soil Database (HWSD). Our multivariate regression models produced quite good prediction accuracies, with differences of approximately 8-15% from the governmental statistics of corn and soybean yields. The unfavorable conditions of climate and vegetation in 2012 could have resulted in a decrease in yields according to the regression models, but the actual yields were greater than predicted. It can be interpreted that factors other than climate, vegetation, soil, and fertilizer may be involved in the negative biases. Also, we found that soybean yield was more affected by minimum temperature conditions while corn yield was more associated with photosynthetic activities. These two crops can have different potential impacts regarding climate change, and it is important to quantify the degree of the crop sensitivities to climatic variations to help adaptation by humans. Considering the yield decreases during the drought event, we can assume that climatic effect may be stronger than human adaptive capacity. Thus, further studies are demanded particularly by enhancing the data regarding human activities such as tillage, fertilization, irrigation, and comprehensive agricultural technologies.
