Since Korean housewives are responsible for the dietary practices of family at home, it is important to know what information will make them to buy safe food. This study was designed to determine the role of perceived threats, behavioral assessments, and self-efficacy factors known to promote healthy behavior in health belief models (HBM) based on food safety awareness and behavior of housewives. This study involved 191 housewives, based on key variables such as perceived severity, perceived susceptibility, perceived benefits, perceived barriers, self-efficacy, and purchase behavior. The results showed that higher levels of education and urbanization increased the threat perception and the likelihood of buying safe food. The correlation analysis showed that increased awareness and knowledge of safe foods and interest in health contributed to higher relative benefit or self-efficiency of food, and thus, ensured food safety. The conceptual model of food safety behavior based on the HBM was verified via structural equation analysis. The findings suggest that a suitable model showcasing knowledge levels and relative benefits resulted in a greater impact on purchasing behavior than perceived threats. This study suggests that it is more effective for housewives to provide more preventive information than risk information to purchase safe food.

One of the limitation for Agrobacterium-mediated transformation via organogenesis from cotyledon explants routinely in cucumber is the production of chimeric plants. To overcome the limitation, Agrobacterium-mediated transformation system via somatic embryogenesis from hypocotyl explants of cucumber (c.v., Eunsung) on the selection medium with paromomycin as antibiotics was developed. The hypocotyl explants were inoculated with Agrobacterium tumefaciens strain EHA101 carrying binary vector pPTN290; then were subsequently cultured on the following media: co-cultivation medium for 2 days, selection medium for $5{\times}14$ days, and regeneration medium. The T-DNA of the vector (pPTN290) carried two cassettes, Ubi promoter-gus gene as reporter and 35S promoter-nptll gene conferring resistance to paromomycin as selectable agent. The confirmation of stable transformation and the efficiency of transformation was based on the resistance to paromomycin indicated by the growth of putative transgenic calli on selection medium amended with 100mg/L paromomycin, and GUS gene expression. Forty eight clones (5.2%) with GUS gene expressed of 56 callus clones with resistance to paromomycin were independently obtained from 928 explants inoculated. Of 48 clones, transgenic plants were only regenerated from 5 clones (0.5%) at low frequency. The histochemical GUS assay in the transgenic seeds ($T_1$) also revealed that the gus gene was successfully integrated and segregated into each genome of transgenic cucumber.

With the development of digital technologies, CAID became an essential part in the industrial design process. Creating photo-realistic images from a virtual scene with 3D models is one of the specialized task for CAID users. This task requires a complex interface of setting the positions and the parameters of camera and lights for optimal rendering results. However, the user interface of existing CAID tools are not simple for designers because the task is mostly accomplished in a parameter setting dialogue window. This research address this interface issues, in particular the issues related to lighting, by developing and evaluating TLS(Tangible Lighting Studio) that uses Augmented Reality and Tangible User Interface. The interface of positioning objects and setting parameters become tangible and distributed in the workspace to support more intuitive rendering task. TLS consists of markers, and physical controller, and a see-through HMD(Head Mounted Display). The user can directly control the lighting parameters in the AR workspace. In the evaluation experiment, TLS provide higher effectiveness, efficiency and user satisfaction compared to existing GUI(Graphic User Interface) method. It is expected that the application of TLS can be expanded to photography education and architecture simulation.

The development of digital technologies transforms the design targets, characteristics of the targets and the role of designers. The paper highlights the role of prototyping in the interactive digital product design process and presents the survey and analysis of prototyping tools that can be used by designers in designing such products. From the review of tools in design related fields. the classification framework for the tools were presented. The framework has the criteria of the fidelity of prototypes, the stage when the prototyping is used, and design targets. Based on the analysis, the implications for using the tools are suggested. They includes that prototyping is important in the concept stage for designers and different tools and methods are to be applied according to design targets and objectives. Prototyping tools need to support exploring design concepts without being constrained by implementation technologies The collaboration with other professionals can also help effective prototyping. Existing tools familiar to designers can be effective platforms for the new design problems. The results can be guidlines with which designers choose more appropriate prototyping tools when they face new design problems. It also make practical contribution in improving design efficiency and design education for interactive product design projects.

The purpose of this study was to develop the level-defferentiated Web Based Instruction(WBI) program, to examine its effects on the science achievement self-directed learning characteristics, and the students’ perceptions on the WBI learning. For this purpose, the advanced and complementary WBI program of level-differentiated curriculum was developed to adapt to class fields and examine instruction facilitating efficiency. Designed and developed the WBI program make it possible to teach students according to the level-differentiated learning for the chapter, ‘weather and climate’ in high school science curriculum. The results of this study are as follows: First, level-differentiated WBI was effective to encourage self-concept, learning eagerness, future-oriented self-apprehension, creativity, self-assessment of the student’s self-directed teaming characteristics. There was no interaction effect of treatment and students’ learning ability at the self-directed learning characteristics. Second, the scores of science achievement of WBI group were significantly higher than those of conventional lecture group. There was interaction effect of treatment and students’ learning ability. However level-differentiated WBI has no effect on openness, initiative, responsibility of the student’s self-directed learning characteristics. There was interaction effect of treatment and students’ learning ability at the science achievement, Third, in the perception questionnaire of WBI teaming, many students showed the WBI teaming was good in terms of causing interaction between learners and web based learning materials including various images and animations. However there are several students who showed learning difficulties. For example they wonder which part is more important and what order is proper to study in hypertext environment.

This study makes differentiated regulations which can maximize the efficiency and convenience of radiation safety regulations by deriving evidence required to establish reasonable safety regulatory structure based on the determination of the levels of actual radiation safety regulations for radiation safety managers to perform radiation safety. We surveyed approximately 10% of radiation safety managers from domestic radiation-using organizations which was based on the Nuclear Safety Act and NUREG Vol. 1~21 of RS-G-1.9 (2005), NRC of IAEA, etc. The radiation safety managers showed the highest level of awareness on the requirements for exposure management ($3.32{\pm}0.910$), and the lowest level on the requirements for record keeping and storage of documents ($2.84{\pm}0.826$). Industrial organizations showed higher levels of awareness than medical organizations whose regulations should be more stringent on requirements of the status and management of radioactive sources, facilities, measurements, pollution control, measuring equipment, monitoring, education and training, and exposure management. This suggests that the actual regulations need to be re-evaluated because it is attributed to the regulations which are statistically significant difference of the levels of radiation safety regulations between industrial organizations and medical organizations. The process of developing regulatory requirements for each characteristic of domestic organizations needs to be done in future studies, as well as safety regulations to maximize convenience should be achieved if radiation safety regulations are conducted in consideration with the characteristics of each organization.

Various slope protect systems are applied to the slope located around the major facility to maintain stability, and the applied these systems play an important role in protecting the structure by ensuring the safety of the slope. Reinforcement techniques ensure complete safety at the time of application to the slope, but over time, it may become difficult to secure safety. In particular, the deterioration of reinforcement systems may significantly reduce the stability of the slope. Therefore, it is necessary to secure the safety of the slope by defining the necessary items for maintenance of the protect systems and verifying them by the field expert. In this study, a group of experts were formed to determine these items and select their importance among them, and based on their data, the importance of each item was selected by Analytic Hierarchy Process (AHP). The selected items are expected to play an important role in the maintenance of reinforcement systems applied to the slope based on the survey items used by experts.

This study was carried out to examine the actual condition of health promotion program through oriental medicine in the health center and to provide basic data to develop proper policy of oriental medical health promotion program for the community people. The data were collected from 26 health centers which have been implementing the oriental medical health promotion program, using selfadministered questionnaire for two weeks from 1 October to 15 October 2006. The results are as follows : Generally, the respondents have the positive views on the level of budget and facilities/equipments of the oriental medical health promotion program in health center. However, they have the negative views on the level of manpower and education/training of the program. And also more than 70% of the respondents have the negative opinion on capabilities of formulating and evaluating the oriental medical health promotion program. The respondents indicated that there was the lack of coordination between the oriental medical health promotion program and existing health promotion in health center, and that low rate of utilizing community resources. With regard to the method of selecting the target group for the program, there are differences according to the each program. Many programs tended to select the target group not through the criteria of life-course and illness group but through the efficiency of selecting group. And many programs such as stroke prevention program, constitutional medicine program, oriental medical prenatal program, oriental medical prenatal and postnatal program, oriental medical child care program are mainly composed of the development of educational program and lecture. Regarding the number of the present oriental medical health promotion programs, around 65% of respondents answered that the number of the programs was many and thus they needed to decrease to the proper level. And with regard to the priority of the need, effectiveness and the satisfaction for each programs, on the whole, Qui gong program, stroke prevention program, area-specialty program and oriental medical home visiting program have high score. In particular, oriental medical quit-smoking program has lowest score. From these results, it requires to develop and improve the oriental medical health promotion program in health center considering the need and characteristics of community.
