The aims of this study are to investigate the environmental perception of elementary school students through picture drawing and associated words about environment, and analyze whether there are differences in the environmental perception according to living places and grades. The drawing of 230 students are analysed and categorized into the criteria. The results are as follows: a number of students realized as images associated with natural environment for words related to environment. In the pictures of the 'positive environment', expression frequencies of natural environment and living things were higher than ones of artificial environment and non-living things. On the other hand, there were many pictures expressed as pollutions of waste, air and water in the pictures of the 'negative environment'. Comparison of environmental perception between rural and urban students showed a significant difference all in the two criteria. There was, however, no difference in the environmental perception between grades. Therefore, it is suggested that student's minds about the sentimental situation can be studied and they can be guided in positive directions to lead their future life in environment-friendly education rather than pollution education.

The purpose of this article was to examine the influence of physical environment on customer's buying-risk perception at franchise Korean restaurants. In this research factor analysis and multi regression analysis were used. Physical environment were divided to 3 factors and risk perception to 5 factors. Internal environment affected negatively financial risk (p<0.001), time risk (p<0.001) and psychological risk (p<0.001). External environment had negative influence on time risk (p<0.05) and psychological risk (p<0.05). And the other environment negatively affected financial risk (p<0.001), time risk (p<0.001) and psychological risk (p<0.05). According to these results, we confirmed that various physical environments influenced on the risk perception of customers. As a result, food service corporations need to deal with physical environment efficiently. And the findings of this research would help their business management to build effective service marketing strategies and to satisfy the needs of customers at franchise Korean restaurants.

This study begins with a review of commonly discussed dimensions of public risk perception that may influence public opinion toward risks. Factors that have been revealed by the literature to have substantial impact on risk perception, such as demographic background, trust, and media environment, are also discussed. Meanwhile, we evaluate two well-known research models in the realm of risk analysis: 1) the psychometric paradigm, and 2) the social amplification of risk framework (SARF). Based on a literature review, this study suggests that, besides the psychological and social approach, models of risk perception and risk communication research should shift to a more comprehensive one by considering the interrelations between laypeople and the environment. This study proposes a research model from the perspective of social cognitive theory (SCT) as a potential framework for future studies: 1) in the societal environment, individuals' risk perception and information seeking behavior, which is determined by risk perception will be influenced by trust in regulators and interpersonal trust; 2) in the media environment, individuals' risk perception and information seeking behavior will be influenced by individuals' perceived information characteristics. Knowledge about risk accumulated through information seeking will change risk perception in a longitudinal process.

The purposes of this study were to determine the factors that influence job satisfaction for ICU nurses and to analyze group differences in job satisfaction based on the nurses' preference and perception of the work environment with an enhanced professional role. A total of 231 nurses who had been working in Intensive Care Units at least for 6 months at selected university hospitals participated in the study while head nurses or those with administrative positions were excluded. The study participants had an average of 33 months of clinical experience with an age range of 23 to 40 years. The data were analyzed by utilizing SPSSWIN and the results are as follows. 1) Hierarchical multiple regression analysis showed that work characteristics defined by Job characteristics theory and nurses' preference / perception of ideal work environment together explained 33% of variance in job satisfaction. Skill variety, task identity and autonomy as well as individual perception of work environment were significant variables for explaining job satisfaction. Job satisfaction was not significantly related to age, marital status, education, and clinical experience. 2) The groups classified by nurses' preference and perception of work environment were significantly different in their job satisfaction. Nurses with high preference and high perception showed significantly higher general and specific job satisfaction than other nurses. The nurses who showed high preference but perceived their work environment as not reflecting ideal job characteristics reported the lowest job satisfaction among the groups. In conclusion, the role of individual preference and perception of the work environment in explaining the relationship between the redesign of work environment and job satisfaction was supported by the study, The preferences of nurses to the innovative work characteristics should be considered in the process of enhancing job characteristics to lead job satisfaction and low turnover and ultimately to improve quality of care.

Purpose: The purpose of this study was to investigate the factors increasing fall risk in the residential environment risk and the perceived fall risk among the older adults who received home care services to provide information for developing a comprehensive falls intervention program. Methods: The subjects were 227 community-dwelling elderly aged 65 years and over who were taken care of by home-visiting nurses of the national health centers. The data were collected from July to August in 2012 using the Choi's residential environmental risk scale (2010) and the Hong's fall risk scale (2011). Results: Requires an assistive devices to walk, modified residential environment, health security, approval certificate of LTC, residential safety perception, residential environment risk, and perception of fall risk were statistically significant risk factors. A multiple logistic regression analysis showed that room & kitchen, physical perception, medication & ADL perception, floor-related environmental perception, and daily living tool-related perception were statistically significant predictors of fall. Conclusion: The results showed that the residential environment and the perceived fall risk were associated with fall experiences among the elderly. It is necessary to develope multifactorial intervention programs considering both environmental and perceived risk factors as well as physical risk factors to reduce and prevent falls among the elderly.

The eyes are the first sensory organs to perceive the environment. We become accustomed to the environment with our eyes. When we contact the environment, we perceive the appearance of an object with our eyes. Then we recognize our position, and perceive the shape surrounding the object interacting with space. The perception of seeing constructs experiences which control most of our recognition, and the experiences are images of the environment surrounding it. So they are significantly expressed into sensitive and mental elements of material and non-material world. Gibson's ecological perception theory analyzes and information system, which helps man to move effectively, and its component stimulus'. The important thing is that we should understand the combination of systems gathering stimulus not as an individual system but as one whole system.

As recent virtual reality technologies provide a more natural three-dimensional interactive environment, users naturally learn to explore space and interact with synthetic objects. The virtual reality researcher develops a technique that realizes realistic sensory feedback to get appropriate feedback to sense input behavior. Although much recent virtual reality research works extensively consider the human factor, it is not easy to adapt to all new virtual environment contents. Among many human factors, distance perception has been treated as very important in virtual environment interaction accuracy. We study the experiential virtual environment with the feature of the virtual object connected with the real object. We divide the three-dimensional interaction, in which distance perception and behavior have a significant influence, into two types (whole-body movement and direct manipulation) and analyze the real and virtual visual distance perception heterogeneity phenomenon. Also, we propose a statistical correction method that can reduce a near-body movement and manipulation error when changing the interaction location and report the experiment results proving its effectiveness.

This study, through the survey of citizens of Daegu in regard to the environment education experience and citizens perception, seeks to identify the order of importance and perception on the severity of environment. The survey has found that 36.4% citizens of Daegu have environment education experience. Those who have experience have high standard of living, live in high population density area and where pollutant generating plants are prevalent. In addition they are likely to live in apartment, are younger, and the higher the education level, more opportunities they have in getting environment education. The study has found that the environment education experience gives noticeable influence on environment perception, environment attitude, and environment activities. Also, those who have the environment education are likely to be interested in environment, know green growth policies, and are positive about local environment activities. Thus, they are willing to participate in activities to improve local environment and have emphasized the need for more environment education. As for what environment elements are most severe, they pointed to the "global warming and climate change" and "everyday garbage" and as for what are important, they chose "drinking water quality" and "global warming and climate change." Based on the study, we came to the conclusion that more environment education should be provided to elevate the interest in environment and subsequently, foster the sense of responsibility and civic mind toward the preservation of environment. In light of above, local governments must expand their supports and fully utilize the Local Agenda 21 to promote the education and increase the perception of citizens on the environment.

The long-term perception investigation of environment is needed for the persistence of each country's policy on climate change, which is greatly influenced by external factors. Long term data on perception and attitudes of people's thought can be a big data point for climate change and consistent policies can be implemented with the need for public demand. Information on the perception of the general public regarding the environment should be carried out as a basis for the national environmental policy.
