Purpose: The purpose of this study was to research the display of optician's shop through questionnaire to suggest the direction for more effective display method. Methods: The study visited 50 optician's shops located in main area of Ulsan (university street, downtown and residential street), performed questionnaire and researched optician's display preference. Results: The displays preferred by opticians were as follows. They displayed contact lens in entrance of shop, displayed sunglasses in the wall rather than displayed them in the center of shop and displayed medium or low price products in the center so that consumers could access them conveniently. In addition, they prepared resting place for customer's convenience by locating it in entrance or inside of shop. Conclusions: It seems that effective display of optician's shop can attract consumer's mind and improve purchase, resulting in significant change of optician's shop sales. Therefore, it is necessary to perform the study to use systematic, discriminated display strategy so that shop image can be controlled consistently and continuously.

Purpose: To investigate consumer satisfaction of foreigners with eye-wear products in Korea. Methods: Foreigners (n=106, United State/Canada, Japan, China, or other Asia) who have purchased the products at optical shops in Korea, were volunteered. Satisfaction factors were categorized into 6 divisions (products, price, vision correction, facilities, kindless, description). Results: The most frequently purchased products were eye-glasses (62%) and sunglasses (25%) by foreigners at Korea's optical shops. Quality satisfaction of the products was higher to Chinese and other Asians than to American, Canadian and Japanese. Price satisfaction was higher to Japanese, American, and Canadian than to Chinese and other Asians. Vision correction and facilities satisfaction were appeared relatively low from American and Canadian. Product descriptions and kindness were, in general, lower than other categories to all nationalities. Conclusions: Satisfaction about eyewear were significantly different depending on the nationality of the foreigner. Based on the various categories of the consumer satisfaction, ethnically customized marketing strategy would be possible to foreigners who stays in Korea.

Purpose: This study was investigated to evaluate the effect of the variation of the face form angle(FFA) of spectacle frame on the visual acuity and the visual function. Methods: The visual acuity, the contrast sensitivity, the stereopsis, and the phoria were measured with the spectacle frame whose the FFA is at $5^{\circ}$ and $25^{\circ}$ and the surveys were conducted on subjective symptoms. Here, 30 adults (14 men and 16 women, average age:$25.46{\pm}3.9$), who did not have ocular diseases and were fully corrected in case of having had refractive error, were to act as experimental subjects for this measurement. Results: The visual acuity and the contrast sensitivity was decreased and the phoria was tended to increase to the esophoria direction at the FFA $25^{\circ}$ than at the FFA $5^{\circ}$. The stereopsis was significantly reduced at the FFA $25^{\circ}$ than at the FFA $5^{\circ}$. Also when the FFA was larger, the higher the degree of refractive error was, the more the increase of the subjective symptoms such as being blurred characters, being disturbed head, and having sore eyes was, which reveals a statistically significant correlation between them. Conclusions: If the FFA increases, the visual acuity, the contrast sensitivity and the stereopsis was found to decrease and the phoria to increase to the esophoria direction. Therefore it shows that the variation of the FFA of spectacle frame can influence the visual acuity and the visual function.

This study was aimed to investigate factors that affected the status of wearing personal protective equipment (PPE) for handling poultry carcasses with potential exposure to virulent avian infectious agents. A large outbreak of high pathogenic avian influenza (HPAI) occurred in South Korea in 2014. Many public officers participated for euthanizing and handling livestock carcass. However, several safety issues with using PPE were revealed. Therefore, a questionnaire survey was conducted for 340 people who participated euthanasia and carcass disposal in the place where HPAI mainly occurred in 2014. It was found that 31.8% of the respondents had ever taken off their protective equipment during operations because of its inconvenience. The most inconvenient PPE was goggles (54.6%), followed by mask (20.2%), latex gloves (11.6%), shoe covers (5.9%) and protective clothing (5.3%). The main complaints about this individual PPE was unclear sight, damp emitted toward eye, sweating, tearing easily and sweating, respectively. Considering such problems of PPE, new possible directions for improvement of gloves and goggles were suggested. With newly developed rubber coating fabric gloves and conventionally using latex and fabric gloves, H3N2 influenza virus transmission experiment was conducted. Rubber coating fabric gloves showed similar efficiency for blocking virus transmission with latex laboratory gloves and were not easily torn by sharp claws of chicken. In addition, air flow control safety eyewear was suggested to minimize moisture formation. The air flow control system efficiently suppressed moisture formation inside the goggles. Therefore our study will provide more specific directions about new PPE development for safety protection of actual wearers.

The 'hands-on' craftsmanship of the 20th century has came and gone. Today, we are dealing with whole new, 'cerebral approach,' to concept and design with this new approach, design and function are very much dependant upon planning, sales, promotion, and the formative technique of the design industry. The innovative process of design constantly change as it reflects the needs and wants of society. It is and industry that constantly change as it reflects the needs and wants of society. It is and industry that constantly remakes and reshapes itself to suit current trend and outlook. The current idea being that consumers are looking for quality over quantity. Due to the 20th centuries dominant philosophy of functionalism, production intended to standardize the individual's purchasing choice. Aesthetic, or philosophic qualities played a second fiddle to the functional bias of a product, With production, Marketing, and research and development are integrated into the management process. This translates as good which include efficiency, quality, durability, and credibility an trademark and style. There is a definite 'post-modernist' movement and style in 21st century. Every possibility is available as the old boundaries of the 20th century are laid aside. There is a new, transformative quality to the current paradigm of design. The old "should" and "should not" of design no longerapplies. The integrated rative of design solves the usual disparity between aesthetic qualities and production. Design and profirability need not be stranger to one another. It can differentiate the image perceived of both enterprises and consumers by making use of integrated goods services. With an integrated system. both producers and designers win. While design gets full access to design in turn. All consumers make decisions based upon the evaluation of quality, service, and image ; even though it may not be a conscious decision to do so. Consumers are fully integrated human beings ; therefore producers who apply the new, integrated paradigmatic approach to concept, design, and production will reap the harvest of making a true relationship with individual buyer.
