  • This study's objects are to predict distribution and to assess vulnerability of sub-alpine vegetations in the Korean peninsula for climate change using various climate models. This study validates relationship between sub-alpine vegetations and environmental factors using Pearson correlation analysis. Then, the future distribution of sub-alpine vegetations are predicted by a logistic regression. The major findings in this study are; First, spring mean temperature (March-May), total precipitation, elevation and warmth index are highly influencing factors to the distribution of sub-alpine vegetations. Second, the sub-alpine vegetations will be disappeared in South Korea and concentrated around Baekdu Mountain in North Korea. North Korea is predicted to have serious impact of climate change because temperature will be increased higher than in South Korea. The study findings concluded that the assessment of the future vulnerability of sub-alpine vegetations to climate change are significant.

  • Tourist industry has many sensitive issues with climate change and is worthy of study from an aspect that it could provide new opportunities and threats from the low-carbon - green- growth point of view. To study how the change of awareness and attitude of the customers due to climate change affects the tourism demand and tourism choices is very important. Even at present, the effect is ongoing. In this paper, diverse needs and changes of tourists, who are the subjects of tourism activities, have been grasped through the examination of psychological characteristics according to climate change after defining the influencing relations of tourism experience, tourism value, tourism risk factors, satisfaction, and behavioral intention, affected by awareness of climate change and their attitude toward it. Through this, the implications that are necessary for establishing marketing strategies could be provided. The results of this present paper are as follows: First, it was shown that awareness of climate change did not affect tourism risk factors while it had a significant influence on tourism experience and tourism value. Secondly, it was revealed that the Chinese tourists generally influenced more greatly than the Koreans. Thirdly, it was shown that the attitude toward climate change did not affect tourism value while it influenced significantly on tourism experience and tourism risk factors. Fourthly, it was revealed that tourism risk factors did not affect tourism satisfaction while tourism experience and tourism value had a significant influence on tourist satisfaction. Fifthly and last, it was shown that tourism experience, tourism value, and tourism risk factors did not influence behavioral intention respectively.

  • This paper tried to apply psychosocial factors in industrial safety research. Since Zohar's(1980) publication of safety climate in the field of safety research, this approach have been done by many researchers. Here, this paper reviewed the relationship between safety climate factors(safety rule, prevention, superior attitude, social support) and safety compliance, and the moderating effects of work condition, required skill and age. Based on the responses from 233 employees in Kangwon province industry, hierarchical regressional analysis showed that all safety climate factors(safety rule, prevention, superior attitude, social support) have positive relationship with safety compliance. Safety rule appeared to be more positively related with safety compliance, while work condition is more favorable and worker is older. But social support appeared to be more positively with safety compliance, while work condition is more unfavorable, and also prevention appeared to be more positively with safety compliance, while worker is more younger.

  • Objectives: Infectious diseases are known to be affected by climate change. We investigated if the infectious diseases were related to meteorological factors in Korea. Methods: Scrub typhus, hemorrhagic fever with renal syndrome (HFRS), leptospirosis, malaria and Vibrio vulnificus sepsis among the National Notifiable Infectious Diseases were selected as the climate change-related infectious diseases. Temperature, relative humidity and precipitation were used as meteorological factors. The study period was from 2001 through 2008. We examined the seasonality of the diseases and those correlations with meteorological factors. We also analyzed the correlations between the incidences of the diseases during the outbreak periods and monthly meteorological factors in the hyper-endemic regions. Results: All of the investigated diseases showed strong seasonality; malaria and V. vulnificus sepsis were prevalent in summer and scrub typhus, HFRS and leptospirosis were prevalent in the autumn. There were significant correlations between the monthly numbers of cases and all the meteorological factors for malaria and V. vulnificus sepsis, but there were no correlation for the other diseases. However, the incidence of scrub typhus in hyper-endemic region during the outbreak period was positively correlated with temperature and humidity during the summer. The incidences of HFRS and leptospirosis had positive correlations with precipitation in November and temperature and humidity in February, respectively. V. vulnificus sepsis showed positive correlations with precipitation in April/May/July. Conclusions: In Korea, the incidences of the infectious diseases were correlated with meteorological factors, and this implies that the incidences could be influenced by climate change.

  • This study investigated the variability of spring (March-May) forest fire risk in Korea for the period 1991~2017 and analyzed its relationship with large-scale climate factors. The Forest Weather Index (FWI) representing the meteorological risk for forest fire occurrences calculated based on observational data and its relationship with large-scale climate factors were analyzed. We performed the empirical orthogonal function (EOF) analysis on the spring FWI. The leading EOF mode of FWI accounting for about 70% of total variability was found to be highly correlated with total number of forest fire occurrences in Korea. The high FWI, forest fire occurrence risk, in Korea, is associated with warmer atmosphere temperature in midwest Eurasia-China-Korea peninsula, cyclonic circulation anomaly in northeastern China-Korea peninsula-northwest pacific, westerly wind anomaly in central China-Korea peninsula, and low humidity in Korea. These are further related with warmer sea surface temperature and enhanced outgoing longwave radiation over Western Pacific, which represents a typical condition for a La $Ni\tilde{n}a$ episode. This suggests that large-scale climate factors over East Asia and ENSO could have a significant influence on the occurrence of spring forest fires in Korea.

  • In this study, we constructed using Random Forest(RF) by selecting the meteorological factors related to the occurrence of frost. As a result, when constructing a classification model for frost occurrence, even if the amount of data set is large, the imbalance in the data set for development of model has been analyzed to have a bad effect on the predictive power of the model. It was found that building a single integrated model by grouping meteorological factors related to frost occurrence by region is more efficient than building each model reflecting high-importance meteorological factors. Based on our results, it is expected that a high-accuracy frost occurrence prediction model will be able to be constructed as further studies meteorological factors for frost prediction.

  • Whilst it is clear that increasing temperatures from global environmental change will impact the positions of alpine treelines, it is likely that a range of regional and local scaled factors will mediate the overall impact of global scale climate drivers. We summarized 12 categories of abiotic and biotic factors as 4 groups determining treeline positions. First, there are global factors related to climate-induced growth limitation and carbon limitation. Second, there are seven regional and local factors related to treeline dynamics including frost stress, topography, water stress, snow, wind, fire and non-fire disturbance. Third, species-specific factors can control treeline dynamics through their influence on reproduction and life history traits. Fourth, there are positive feedbacks in structuring the dynamics of treelines. Globally, the commonly accepted growth limitation hypothesis is that growth at a treeline is limited by temperature. Meanwhile, positive feedbacks between canopy cover and tree establishment are likely to control the spatial pattern and temporal dynamics of many treelines. The presence of non-linear dynamics at treelines has implications for the use of treelines as barometers of climate change because the lagged responses and abrupt shifts inherent in non-equilibrium systems may combine to mask the overall climate trend.

  • This research identifies the main factors of the psychological climate that directly affect the performance of banking employees in Vietnam. Besides, this research also takes into consideration the differences in gender, age, educational level, and income on working performance. A survey was obtained from 207 employees working at joint-stock commercial banks and the analysis was handled with SPSS 20 software supports. The result shows that the measurement scales meet the requirements of validity and reliability. Regression analysis demonstrates that there are four factors directly affecting the working performance: friendliness, personal development and learning opportunities, straight and open communication, and the support from the senior management. These four factors have created a healthy psychological climate in the banks, where employees will feel comfortable and happy to improve work performance. Furthermore, this research has found that the higher the income, the more efficiently employees will work. The results of this research contribute to the measurement scale of working environment factors. At the same time, this research also proposes some recommendations for organizational managers to build a reasonable working environment that can inspire a sense of mental comfort for employees to work at their full capacity and to achieve the highest performance.

  • This study developed the Creative Classroom Climate Scale(CCCS) for Elementary Students, verified its validity and reliability, and examined relationships among creative thinking, personality and motivation. Three professionals examined the content validity of the CCCS after the items were developed by the researcher. The CCCS and the Creativity Inventory for Young Students(CIS; Choe & Lee, 2004) were administered to 266 6th grade students. Results showed that the CCCS was valid and reliable including the sub-factors of Support, Trust, Tension, Playfulness, Conflict, Challenge and Communication. The sub-factors correlated significantly with total scores. CIS scores varied by the creative climate of the classrooms on the CCCS; creative motivation was especially influenced by classroom climate.
