This paper presents basic supporting data necessary for planning an educational intervention strategy as part of a communication strategy that would form an extensive national consensus on and enhance national understanding of irradiated foods. A survey was conducted to collect data on the knowledge, attitude, and behavior with regard to irradiated foods among high school students, on whom education has a great ripple effect compared with the general public. The results show that 82.9% (627 students) have acquired no information, whereas 89.3% (675 students) have received no education on irradiated foods. The reason for these overwhelmingly large percentages is the lack of available opportunity for education(88.2%). Their level of knowledge on irradiated foods scores 1.71 points (out of 10 points), which is very low, whereas their attitude toward the safety of irradiated foods scores 2.76 points (out of 5 points), which is relatively low as well. As such, we predict that their tendency to purchase and consume irradiated foods is low, given their very low level of knowledge of and negative attitude toward irradiated foods. The students who have been educated on irradiated foods show a higher level of positive attitude (p<0.001) toward irradiated foods compared with those who have had no education. This result suggests the need to provide high school students with knowledge on irradiated foods as well as education in the same to help them form a proper attitude toward these food items.

In the 21st century, university education is changing from an objective knowledge and information to critical thinking and problem-solving ability. Moreover, university education should change rapidly towards a learner-centered educational environment because it has an educational goal to have college students experience authentic tasks they will be in charge of after graduation, and improves self-directed learning ability and cooperative learning ability. PBL is a pedagogical strategy for posing significant, contextualized, real world situations, and providing resources, guidance, and instruction to learners as they develop content knowledge and problem-solving skills. In problem based learning, the students collaborate to study the issues of a problem as they strive to create viable solution. For these advantages of PBL, the application of PBL in school has been enlarged. On the other hand, the application of PBL in engineering education has not been enlarged. To improve these instruction methods, the development or applications of new instructional methods will be needed. This study examined the PBL instructional design of a creative engineering design subject, which aims to foster talent. The PBL model developed in this study consists of Analysis, Design, Development, Implementation, and Evaluation. A plan of creative engineering design subject was developed based on PBL, and focused on the process of PBL. To determine the effects of this model, studies applying this instructional design to many lecturers should be implemented.

This study was carried out to estimate the risk of pesticide operators who use high toxicological pesticides. The class II (highly hazardous) pesticides registered in korea were 15 products, and 11 products were spray type pesticides at orchard file in 2009. The using information based on the pesticide label and the data searched through survey of actual condition on pesticides were used for calculate the pesticide operator exposure dose. The risk quotients of these pesticides against the pesticides operator were calculated as devide pesticide exposure dose by reference dose which were presented by EFSA (European Food Safety Authority), JMPR (Joint FAO Meeting on Pesticide Residues), and US/EPA (United States Environmental Protection Agency). Omethoate showed the highest risk quotient and the values were 338 and 75 when the operator spray using speed sprayer and motor sprayer respectively. Risk quotients of all class II pesticide were above 1. This result means that the risk potential of these pesticides are very high.

The purpose of this study was to investigate factors of perception by inpatients of the Medical Examination institutions about exposure to radioactivity at the time of radioactive examination, providing basic information for making educational materials aimed to change their perception. Most of those patients, 72.0% responded that CT was a type of radioactive examination bringing highest exposure to radiosensitivity. Most of the subjects, 63.5% said that a body part most vulnerable to exposure to radiosensitivity was the genital gland at the time of radiosensitivity examination. And most of the participants, or 29.0% responded that they obtained information about radiation from TVs or newspapers. Among the surveyed patients, men were higher in scores for factors of the perception of radiation such as recognition of radiation, harmfulness of radiation, psychological state at the time of radioactive examination, prevention of exposure to radioactivity and necessity of radiation that women were, with statistically significant differences between the two groups. These findings suggest that it is urgently needed to develop an education program which helps patients better perceive exposure to radioactivity and that radiologists should be very careful to reduce the does of that exposure. If patients better perceive radiation, they would be less anxious and less exposed to radioactivity when receiving the radioactive examination.

This study was conducted to identify factors affecting acculturation stress among Chinese students in Korea. 239 Chinese students in Korea were surveyed using a structured questionnaire from September 1, 2014 to January 31, 2015. The results were as follows. The subjects' acculturation stress was 3.29 out of 5. Their overall spiritual well-being was 3.10 out of 5, and their existential spiritual well-being and religious spiritual well-being were 3.67 and 2.54, respectively. On the other hand, demand for religious activities was 4.37 out of 6. Factors affecting acculturation stress among Chinese students in Korea were age, school year, period of stay in Korea, Korean language skill, demand for religion, and existential spiritual well-being, and their explanatory power was 36.1%. These findings suggest that religious activities need to include programs not only for guiding their lives of faith but also for improving their understanding of Korean culture and their Korean language skill and supporting their practical lives while studying in Korea.

For the purpose of investigating the effect of evaluation on career support by the college and career exploration efficacy of dental hygiene students on the career exploration behavior, a survey was conducted in December 2014 with students of dental hygiene at universities located in Ulsan and Daegu as subjects. In the result, correlation was found among sub-factors of evaluation on career support by the college, career exploration efficacy, and career exploration behavior. Increase of career exploration efficacy (${\beta}=0.702$, p<0.001), practical career support (${\beta}=0.165$, p<0.05), and relationship establishment efficacy (${\beta}=0.152$, p<0.05) led to increase of career exploration behavior, while increase of individual exploration efficacy (${\beta}=.0.242$, p<0.001) led to decrease of career exploration efficacy. Therefore, it is necessary to build appropriate value system related to job seeking, conduct active discussions to increase relationship establishment efficacy by using interpersonal relationship reinforcement program, and expand career support program by the college.

As the world is in the age of globalization and information, we observe diverse changes in the market environment. Since wide-spread internet services and global networks made ubiquitous learning and business possible, equalizing consumers' ideology and preference, new trend and life style could be introduced easily. This study stipulates on the theoretical concept of the wellbeing consumer and LOHAS consumer. Consumers of LOHAS could be sampled out through pre-questionnaire targeting at selected food, clothing, and shelter based on companies of both wellbeing and general brands. Through this it is attempted to measure wellbeing emotion, recognition quotient of emotion and reason, affirmation and negation, mental emotion quotient, and preference in order to find out their value and to ultimately come up with what web design should be aiming at. Conclusions are as follows: Firstly, consumers easily recognize emotional identification from the web pages of wellbeing brand, rather than that of general brands. Secondly, what web pages of wellbeing brand recognize is reason, not emotion. Thirdly, the design of wellbeing brands scored higher than those of general brands in terms of positive aspects such as hospitality and familiarity, and high mental emotion quotient could not affect the consumers' preference toward web design. Fourthly, wellbeing brands win more preference than general brands do, and preference becomes higher after customers' visit to web pages basically. Lastly, sampled emotional adjectives toward the web designs of wellbeing brands marked a aesthetic graph figure, without leaning toward an active or stable one. It is expected that this study can serve as a groundwork to create proper strategies to actively involve consumers in industrial sphere.
