  • Purpose: This study examined the knowledge and perception of hospice-palliative care and terminal care stress among pediatric nurses, and the relationships among these variables. Methods: In this descriptive research study, 154 pediatric nurses who experienced terminal care at least once were surveyed. This study used three scales, including the Palliative Care Quiz for Nursing (PCQN), Perception of Hospice-Palliative Care, and Terminal care stress. Data analyses using SPSS 22.0 included descriptive statistics, independent t-test, one-way ANOVA, Mann-Whitney U test, Pearson's correlation coefficient, and stepwise multiple linear regression. Results: Terminal care stress experienced by the pediatric nurses was significantly related to the perception of hospice-palliative care; the hospice-palliative care education program enhanced the knowledge and perception of hospice-palliative care. Conclusion: Hospice-palliative care education programs should be developed and provided for pediatric nurses to improve pediatric hospice-palliative care. Additionally, further research on this topic is required because the present results are inconsistent with previous and current researches.

  • A simulation-based approach is proposed to study the protective actions taken by residents during nuclear emergencies using cognitive findings. Human perception-based behaviors are not heavily incorporated in the evacuation study for nuclear emergencies despite their known importance. This study proposes a generic framework of perception-based behavior simulation, in accordance with the ecological concept of affordance theory and a formal representation of affordance-based finite state automata. Based on the generic framework, a simulation model is developed to allow an evacuee to perceive available actions and execute one of them according to Newton's laws of motion. The case of a shadow evacuation under nuclear emergency is utilized to demonstrate the applicability of the proposed framework. The illustrated planning algorithm enables residents to compute not only prior knowledge of the environmental map, but also the perception of dynamic surroundings, using widely observed heuristics. The simulation results show that the temporal and spatial dynamics of the evacuation behaviors can be analyzed based on individual perception of circumstances, while utilizing the findings in cognitive science under unavoidable data restriction of nuclear emergencies. The perception-based analysis of the proposed framework is expected to enhance nuclear safety technology by complementing macroscopic analyses for advanced protective measures.

  • Environmental education, effectively performed at school, is very important to solve the environmental problems. Moreover the survey for teacher's perception is essential. The purpose of the study was to investigate the perception of environmental problems of middle school teachers in Pusan. The survey was done twice in 2007 and 2012, and based on the time intervals, careers, and major of the teachers. 200 teachers were chosen in 2007 and 300 teachers in 2012. How many environmental problems occurred during this time period affected the 471 teachers' perception was investigated and analyzed. The results are as follows. First, the perception difference of environmental problems was meaningful between two time intervals (p<.01). Especially, the perception of modern environmental problems and carbon emission showed considerable increase in both science and non-science major teachers. This may be caused by the climate change and the severity of lifestyles of indiscriminate consumerism. Second, the perception difference of environmental problems by careers was also meaningful (p<.01). Overall, the perception was obvious on the aspects of modern environmental problems, carbon emission, destruction of ozone layers, nuclear wastes, environmental hormones, and red tides. Teachers, having more careers irrespective of their teaching subjects, showed higher perception on the seriousness of environmental pollution, the necessity of environmental conservation, and the importance of health. Third, the perception of environmental problems between science and non-science major teachers was meaningful (p<.01). Particularly, the perception in the broad environmental problems was distinctive between them.

  • Human perception is an outcome of the influence of various factors rather than objective reflection of external environment. Among the factors, action-specific perception is a phenomenon where perception changes in terms of one's ability to act on the environment. Previous research reported contradictory results regarding whether action-specific perception occurs during performance or after performance due to memory distortion or knowledge about performance results. In this research, we conducted three experiments to determine when action-specific perception occurs. Participants threw darts at different distances and reported perceived size of targets in each trial. The results showed that, in Experiments 1 and 2, participants perceived targets larger when they hit than missed the targets, and the effect was greater when the targets were not visible after each throw. However, because participants had knowledge about the results of their throws, there could have been bias in participants' responses. In Experiment 3, where this possibility was excluded, we also obtained action-specific perception, and therefore concluded that action-specific perception occurs during but not after task performance.

  • This study examined the influence of perceptions of food risk and food labeling on the purchase of labeled food items and the intention to pay higher prices for safe food. Data were obtained from the Korea Rural Economic Institute's Consumer Behavior Survey for Food 2020. The analysis focused on the responses of 6,355 consumers, all of whom were mainly responsible for food purchases. The analysis investigated the moderating effect of food risk perception on the relationship between food labeling perception and the purchase of labeled food. Regarding the purchase of labeled food, statistically significant effects were noted for gender, educational level, perception of food labeling, and perception of food risk; however, the interaction effect of perceptions of food labeling and food risk was not statistically significant. With regard to the intention to pay higher prices for safe food, except for age, statistically significant effects were observed for gender, educational level, food expenditure, perception of food labeling, and perception of food risk; moreover, the interaction effect of perceptions of food labeling and food risk was significant. The results indicate that consumers reporting low food labeling perception and low purchase of labeled food were most vulnerable regarding food safety; therefore, it is necessary to provide such consumers with food label provision methods and specified education programs.

  • In Korea, the lower elementary grades are applying a topic-oriented integrated curriculum. It causes a lack of science content and inquiry experience for young children. The purpose of this study is to understand the scientific experiences and perceptions of the lower elementary graders and to inquire about the meaning of those experiences in their science learning. Four students (male 2, female 2), their parents, and their first-year homeroom teachers participated in the study. The data collection was mainly conducted through in-depth interview of them. Results showed that the 'experiments' were the student's the main perception of science, and the epistemic emotion that students mainly feel about science was 'curiousness'. Since most experiences were dependent on non-formal educational experience, the parents were an important factor to determine their experiences about science. Various factors, such as students' scientific experiences, their epistemic emotions, and the parents, interacted to form children's perception of science. The positive perception of science affected the level of motivation and expectation for science learning as the third grade. It is suggested that improvement of curriculum and textbooks should emphasize scientific exploration for the lower graders of elementary school, which provides them meaningful scientific experience in school.

  • We investigated the perception and preferred type of question and analyzed type of questions asked by teachers in elementary science class to identify how teachers' perception of questioning is reflected in teaching practices. We collected the data from questionnaires, deep-interview and audiotaped four classes from grade 3 and six classes from grade 6. The data form deep-interview were analyzed interpretively and Blosser' framework of question was used to analyze questions which teachers used in classes. By interpretation of data from questionnaires, the teachers agreed that questioning affects science class in elementary school. There were a little differences in perceptions of questioning among three teachers. They preferred various types of question rather than a specific type. They didn't have a good understanding of questioning. The result showed that the teachers used frequently cognitive-memory question and convergent thinking question, which belonged to closed questions in their science classes. This didn't accord with their preferred types of question. The causes came from objectives of science instruction, degree of understanding about questioning, preference and confidence for science class. From this findings, we suggested that teachers should be given opportunities to take training courses in questioning in order to use effective questioning in science class.

  • The purpose of this study was to investigate the effect of risk awareness on injury experience in quick delivery service workers. Risk awareness has complicate characteristics such as its level of worker and worker's decision about the level of other's risk perception. Data were collected by interview survey with structured questionnaire about injury experience, risk perception, work characteristics, and socio-demographic characteristics of quick delivery service workers by cross sectional survey design in 2012. The sample size was 120 respondent of quick delivery service workers. Statistical method for this study was hierarchical logistic regression method with 3 different models using socio-demographic characteristics and work characteristics and risk perception, etc. The difference between the level of risk perception of quick delivery service and other's was statistically significant effect on the experience of injury. Especially the higher the level of risk perception of quick delivery service workers is than other's, the lower the injury experience of quick delivery service worker is. The limitation of this study can be found in survey design. The future study for investigation of mechanism of the combined effect of risk perception of quick delivery service workers and others on injury experience.

  • 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.

  • The study aimed to investigate the effects of climate adaptability and physical activity adherence on clothing behavior and health perception. Total usable questionnaires were obtained from 352 university students(126 male & 226 female students). Results were gained from the statistical analysis such as factor analysis, cluster analysis, ANOVA, t-test using SPSS 19.0. The results were as follows. First, male students showed higher figures than female students in physical activity adherence, cold adaptability, and health perception but vice versa in clothing behaviors related to the seasons, weather forecasts and the situation. Second, the group which had good physical activity adherence showed adequate clothing behaviors and fine health perception, which meant proper relations between exercise, clothing behavior, and health. Finally, the group which had lower climate adaptability but adequate clothing behavior according to the season showed a fine health perception. The relation between clothing behavior and health perception was checked through this.
