The exhibition activity that a company is rendering to their consumers for the purpose of advertisement, sales promotion and enhancement of company inage get more and more internationalized and specialized. A company is changing from mass production system to small quantity production of various kinds to meet consumer's individualization and differentiation. Also, a company is experiencing a major change in their marketing strategy. As the society is entering on Information Age, the contents that a company intends to give consumer may be different individually. If a consumer is informed wrong information of the goods, a company needs a place to meet consumer face to face where the consumer feels and understands the substance of the goods. This is the current characteristics of Exhibition Media. Based on the result of the current Special Exhibition home and abroad along with background and characteristics of special Exhibition, this study sets a following task reflecting the general trend of social, cultural and economic atmosphere. First, Current Exhibition Industry will be diversified into more Specialized Exhibition, while our Exhibition Industry is very shaky under severe international competition. Also, Exhibition Plan that involves with architecture, interior, graphic, industrial design and advertisement, etc., needs international competitiveness while enhancing identity of Exhibition Plan along with comprehensive marketing strategy in the future. Second, Among most of the local special Exhibitions which invite the general public are normally invited for company public relation contrary to those of U.S.A. and Europe. This signifies of our industrial and social structure's by-product. As the future exhibition become Information Com$$\mu$ication Exhibition which requires specialized technical explanation, the correct description of the goods should be set as a Judgement basis of Exhibition Plan. Third, In parallel with increase of the Exhibition, the equipment expenses of a company goes up continuously. In view of this, a study $$\mu$t be oriented for re-use and curtailment of expenditure of those equipment. Also, as the use of Assembly System B on the rise as a result of diversification of special Exhibition, a study on the development of new material & design for Exhibition Equipment only B required.

In order to survive worldwide competition, today's industries are experiencing strong pressure to introduce higher quality products with lower cost and shorter lead-time. Therefore, the role of design in the process of product development is increasing in significance. In this research, two methods for improving the design capability are proposed: construction of design environment and design automation using 3D CAD system. The designers and design process are the core of product design using 3D CAD system. In order to maximize the design performance, construction of the design environment including selection of a suitable system, designer training for best use of the system, establishment of an efficient design process, and stabilization of the environment are required. A method is suggested to construct design environment by systematizing the contents of the projects and consulting experiences carried out for various categories of business such as electronic devices, motorcycles, electricity parts, sanitary wares, injection molds, and die casing molds. Design automation helps reduce tedious and time-consuming jobs, simplify complicated and error-prone modeling and drawing works to shorten the lead time and improve the product quality. To develop a design automation system, understanding the process and the related knowledge on design are very important before implementing the system using API provided by 3D CAD system. In this research, an eight-step procedure is proposed for the development of a design automation system. These eight steps are analysis of needs, determination of specification, verification of specification using 3D CAD system, inspection of related API functions, programming, field test, application in practice, and maintenance. A case study in which five design automation systems in the design of turbine generators using the proposed method is introduced in detail. These systems play important roles in the generation of various output items including 3D models, drafts, material information, and NC data. The case study shows how effectively the design time is reduced and the quality improved using those systems.

Background: Ginsenosides accumulation responses to temperature are critical to quality formation in cold-dependent American ginseng. However, the studies on cold requirement mechanism relevant to ginsenosides have been limited in this species. Methods: Two experiments were carried out: one was a multivariate linear regression analysis between the ginsenosides accumulation and the environmental conditions of American ginseng from different sites of China and the other was a synchronous determination of ginsenosides accumulation, overall DNA methylation, and relative gene expression in different tissues during different developmental stages of American ginseng after experiencing different cold exposure duration treatments. Results: Results showed that the variation of the contents as well as the yields of total and individual ginsenosides Rg1, Re, and Rb1 in the roots were closely associated with environmental temperature conditions which implied that the cold environment plays a decisive role in the ginsenoside accumulation of American ginseng. Further results showed that there is a cyclically reversible dynamism between methylation and demethylation of DNA in the perennial American ginseng in response to temperature seasonality. And sufficient cold exposure duration in winter caused sufficient DNA demethylation in tender leaves in early spring and then accompanied the high expression of flowering gene PqFT in flowering stages and ginsenosides biosynthesis gene PqDDS in green berry stages successively, and finally, maximum ginsenosides accumulation occurred in the roots of American ginseng. Conclusion: We, therefore, hypothesized that cold-induced DNA methylation changes might regulate relative gene expression involving both plant development and plant secondary metabolites in such cold-dependent perennial plant species.

The purpose of this study is to develop scientist vignettes and to explore their effects to change students' perceptions of scientists, scientific attitudes, and the nature of science. The scientist vignettes developed in this study include research cases on seven scientists, including British zoologist Jane Goodall. Each vignette consists of 4 to 6 pages in consideration of the reading level of elementary school students, and contains illustrations describing the main contents of the text. In addition, scientist vignettes contain descriptions on terms and text boxes explaining the higher concepts, and each vignette contains questions that students can think deeply based on the story of the scientist. To verify the educational effectiveness of scientist vignettes, we investigated changes in their perceptions of scientists, scientific attitudes, and the nature of science in 564 elementary school students. We conducted group interviews with four elementary school teachers. As a result of conducting pre-test and post-test using a narrative questionnaire consisting of 6 questions, students became more sophisticated in the understanding of the science and the characteristics of scientists after experiencing scientist vignettes and their understanding the nature of science changed into a more modern epistemological perspective. Also, in a group interview with teachers, teachers assessed that scientist vignettes would positively affect the understanding of science process skills and the nature of science, and forming a scientific attitude, especially in increasing understanding of the nature of science. We discussed ways to effectively utilize scientist vignettes in elementary school science education based on these result.

Purpose: This study aimed to develop a situation-specific theory to explain nurses' experiences of the COVID-19 crisis. Methods: The participants were 16 hospital nurses who experienced the COVID-19 crisis. Data were collected through in-depth individual interviews from September 2, 2020 to January 20, 2021. Transcribed interview contents were analyzed using Corbin and Strauss's grounded theory method. Results: A total of 38 concepts and 13 categories were identified through an open coding process. The core category found was becoming a pioneering nurse who turns crises into opportunities. The causal conditions were the chaos of being exposed defenselessly to an unexpected pandemic, fear caused by a nursing care field reminiscent of a battlefield, and moral distress from failing to protect patients' human dignity. The contextual conditions were feeling like the scapegoat of the hospital organization, increasing uncertainty due to the unpredictable state of COVID-19, and relative deprivation due to inappropriate treatment. The central phenomenon was suffering alone while experiencing the dedication of the COVID-19 hero image. The action/interactional strategy were efforts to find a breakthrough and getting the nurse's mind right, and the intervening conditions were gratitude for those who care for broken hearts and getting used to myself with repetitive work. The Consequences were becoming an independent nurse and frustration with the unchanging reality. Conclusion: This study provides the foundation for the nurse's situation-specific theory of the COVID-19 crisis by defining the crisis perceived by nurses who cared for COVID-19 patients and suggesting types of coping with the crisis.

Purpose: Brand hearsay refers to information that can be acquired from advertisement, media publicity, and word-of-mouth prior to experiencing products or services of brands. Previous information about brands obtained through brand hearsay affects consumer behavior in choosing brands. Moreover, brand hearsay is an effective communication method in promoting brands to consumers. Thus, bakery franchises need to improve strengths and differentiate characteristics of their brand, thereby attracting more consumers. Therefore, this study investigates relationships the effect of brand hearsay on consumers' brand attitude and brand loyalty in the context of franchised bakery brands. Research design, data, and methodology: A research model was proposed to examine structural relationships between brand hearsay (advertising, publicity, word-of-mouth), brand attitude, and brand loyalty. An online survey was conducted to consumers who had an experience of visiting a franchise bakery. A total of 513 responses were used for data analysis. SPSS 22.0 was used for analyzing general demographics, and SmartPLS 4.0 was used to test validity and reliability of the proposed model. Result: Among attributes of brand hearsay, advertisement and word-of-mouth had positively significant effects on brand attitude, but no significant effect was found between publicity and attitude. Advertisement had a positively significant impact on brand loyalty, while publicity had a negative effect on brand loyalty opposite to hypothesis. Moreover, brand attitude had a statistically significant effect on brand loyalty. Conclusions: In the context of franchise bakeries, brand hearsay contents may change consumers' attitude toward brands but does not increase brand loyalty. Though media publicity does not affect consumers' attitude toward brands, it may decrease brand loyalty when consumers are too exposed to it. In addition, it is necessary to enhance brand attitude to increase brand loyalty of customers. This study provides bakery franchisors and franchisees information about which type of brand hearsay (e.g., advertisement, word-of-mouth, media, publicity) is effective in enhancing brand attitudes and loyalty of consumers. Further studies may include other variables (e.g., trust) in addition to attitude and loyalty, or compare findings based on brand characteristics (e.g., low-to-medium/high prices, store size).
