  • The purpose of this study was grouping students' perception types on the unexpected results in experiments, and looking into how the problem-solving experiment affected the change of these perception types. In order to answer this, interview data were analyzed in terms of perception types, and through analysis of questionnaires carried out at the beginning and the end of the semester, the change of perception types was researched. As a result, perception types of students divided into 'the difference between theory and practice,' 'inexperience of experiment skill,' and 'No reading between lines in manual.' After performing the problem-solving experiment for one semester, the perception of 'the difference between theory and practice' declined, and the desire for 'reading between lines' increased, so the problem-solving experiment influenced on the change of perception positively.

  • This study was aimed at investigating the relationship of stress perception and psychopathology with biological variables such as systolic and diastolic blood pressure. serum total cholesterol high density lipoprotein and triglyceride in 50 adult patients with essential hypertension and 50 normotensive individuals. Both of the groups were matched to each other regarding age, sex, the level of education and BMI(body mass index). Stress perception and psychopathology between the two groups were compared using GARS and SCL-90-R scales. Biological variables such as blood pressure(systolic. diastolic), serum total cholesterol, high density lipoprotein and triglyceride were measured in all the subjects. The results were as follows ; 1) Hypertensive patients scored significantly higher than normotensive individuals in stress perception related to unusual happenings, change or no change in routine and overall global area, respectively. 2) Regarding psychopathology, hypertensive patients scored significantly higher than normotensive individuals in depression. hostility and interpersonal sensitivity. respectively. 3) Systolic blood pressure had a significantly positive correlation with scores of stress perception related to sickness and injury, and change or no change in routine, respectively. Diastolic blood pressure had a significantly positive correlation with scores of stress perception related to change or no change in routine. 4) In hypertensive patients. the level of serum total cholesterol had a significantly positive correlation with scores of stress perception related to unusual happenings. However, the level of serum triglyceride had a significantly negative correlation with scores of stress perception related to changes in relationships, sickness or injury, and change or no chang in routine. 5) There were no significant correlations between scores of stress perception and biological factors in the normotensive group. 6) The level of serum triglyceride correlated negatively with phobic anxiety in hypertensive group. whereas it correlated positively with PSDI in normotensive group. In conclusion, these results suggest that hypertensive patients have higher level of stress perception and psychopathology than normal individuals. In hypertensive patients, their stress perception is suggested to be correlated with serum cholesterol.

  • Psychophysical approaches to the room acoustics have been made in number of researches. The present study is looking at whether the listener's perception of frequency change in rooms are dependent on the acoustics of a listening environment. P(C)s for frequency change in short tones were measured in different listening conditions. Two experiments were carried out to investigate the influence of room acoustics on the listener's perception of frequency change, and its implication for evaluating the acoustics of listening environments were examined and discussed. It was found that the temporal and spectral contents of reflections from room surfaces might be an important factor which influenced the listener's perception of frequency change in a reverberant sound field. This implicates that psychophysical approach by measuring listener's frequency change perception might be an useful tool for evaluating room acoustics. However, cares should be taken, since some individual differences were found to exist with respect to the direction of frequency change.

  • This study analyzes whether a person's visual perception differs according to the kinds of light source. Evaluations of the effects of space, color-tone and texture perception revealed that different kinds of light sources change the perception of finishing material. The perception from directly attached lamps was compared to an environment with both directly attached lamps and supplemental lighting. We found the perception changed with changes in the types of supplemental light source We compared the mean value of each perception and found that perceptions change most when incandescent lights were followed by halogen. Thus, one should account for the changes in perception that occur as a result of these changes.

  • The way to respond to climate change is divided into mitigation and adaptation. So far, the response of climate change has been focused on mitigation. The perception of response of climate change also has been focused on mitigation. However, climate change mitigation and adaptation should be highlighted in a comparable concept as a response to climate change. On the other hand, perception of the public on climate change affects the support or opposition of the general public about climate change-related policies. The purpose of this study is to assess awareness of the general public and stakeholders on the subject of climate change adaptation and to present a basis for a future national climate change adaptation policy. Questionnaire on awareness of climate change adaptation were composed of the climate change and climate change response (mitigation, adaptation) understanding and importance, the seriousness of climate change-related adverse climate event, the need for climate change adaptation measures, the degree of implementation, and the level of government effort for climate change response. Climate change adaptation-related awareness survey was conducted for the general public 1,011 people and stakeholders 101 people by telephone interviews. In this study, the perception survey has a difference in aspect of the contents and methodology. And We were able to present the three characteristics of the general public and stakeholders aware of the subject of climate change adaptation. First, the relative importance of climate change adaptation was relatively low. Second level of awareness about climate change response of the public was significantly lower than the stakeholders. Finally, the need to prepare the implementation of the sectoral level, the first adaptation measures was relatively low.

  • In the present exploration we identified perception of forest dependent communities in relation to impact of climate change on forest ecosystem in and around Chilapatta reserve forest in northern part of West Bengal, India. Purposive sampling method was used for selection of area and random sampling method was used for selection of respondent. The data collection in this study was through questionnaire based personal in-depth interviews. Almost all the respondents (94%) were farmers and rest had occupation other than farming. Almost all the respondents perceived negative impact of climate change on forest though the level of perception varies from very low to medium (0.23-0.52) based on average perception score after assigning score to individual statements. The level of perception on impact of climate change on forest ecology and forest flora of the community is low and very low as the average perception score is 0.39 and 0.23, respectively while, it is medium (0.52) for forest fauna. Alternately their perception on decreased stream/river flow and quick drying of seasonal streams or water bodies is based on their livelihood experience as they depend on these for their domestic and irrigation water use and fish catch for family diet.

  • A recent nationwide survey reported that South Koreans perceive large corporations as the party that should be the most responsible for tackling climate change. This public opinion result offers insight into the argument that defining who is responsible for the climate change issue can guide campaigners and policymakers in designing effective communication strategies. This study examines how attributing responsibility to large corporations can affect behavioral intention to support government policy and regulation via a moderated mediation model of the perceived risk of climate change and corporate social responsibility (CSR). A nationwide online survey of 295 South Koreans was conducted. The findings reveal an indirect effect of responsibility attribution on behavioral intention through risk perception. Moreover, perceived CSR moderated the causal link between risk perception and behavioral intention, such that South Koreans reported higher levels of behavioral intention when they reported higher CSR. However, perceived CSR failed to moderate the indirect effect. These findings have implications for communication processes and policymaking to address climate change problems in South Korea.

  • 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.

  • The present study examined if individual listeners' perceptual variations were associated with their cognitive characteristics indexed by the Autistic Spectrum Quotient (AQ). This study first investigated the perception of the lexical pitch accent contrast in the Kyungsang Korean currently undergoing a sound change, and then tested if listeners' perceptual variations were correlated with their AQ scores. Eighteen Kyungsang listeners in their 20s participated in the perception experiment where they identified two contrastive accent words for auditory stimuli systematically varying F0 scaling and timing properties; the participants then completed the AQ questionnaire. In the results, the acoustic parameters reporting reduced phonetic differences across accent contrasts for younger Kyungsang generation played a reliable role in perceiving the HH word from HL, suggesting the discrepancy between the perception and the production in the context of sound change. This study also observed that individuals' perceptual variations were negatively correlated with their AQ sub scores. The present findings suggested that the sound change might appear differently between production and perception with a different time course, and deviant percepts could be explained by individuals' cognitive measure.
