This study examines the visual effects of surface design utilized in commercial space. In particular, 1 focus on the following three categories: transparency and lighting, electronic surface and media screen, and ubiquitous environments and interface. Unlike the past era in which surface design in commercial space was viewed merely as a means of decoration, it has become more important in the contemporary era because diverse expression techniques in surface design enormously help architects and interior designers embody their own ideas more effectively Moreover, the diversity of surface design expands the concept of cultural space as it provides various graphic elements that reflect human desire for multicultures.

This study investigates the differences between purchasers and non-purchasers of naturally dyed-products in the hobby/leisure, media exposure, usage of media program type, and information sources about naturally dyed-products. Data were collected from a total 213 Korean females ranging from 20 to 59 years old, and in data analyses, there were partially significant differences between the two groups. Compared to non-purchasers of naturally dyed-products, Purchasers of those ones were more interested in traditional fields and nature. They are also more exposed to newspapers and less exposed to TV. Purchasers used more informational and educational programs as well as personal and commercial information sources (store visual presentations and sales persons) than non-purchasers. However, the differences between these two groups were not significant in the interests of fashion/cooking and sports, Internet exposure, entertainment programs and public/commercial information sources about naturally dyed-products. Marketers can use the results to access the market of naturally dyed-products for promotion.

This study focuses on defining the new meaning of immateriality in the present times expressed on space. The purposes of this study were to examine the characteristics of immateriality showed in commercial interior design in Korea, based on the definition of immateriality concept and the analysis of the way it is expressed. The result of this study is as follows; it categorized characteristic of material expression, space concept and media. Characteristic elements can be classified into 6: transparency, implication, off-gravitation, ambiguity of boundary, temporality, interactivity. Expression of immateriality in commercial interior space was obtained in many different ways, which are identified: new expression of material by reduction of materiality, leveling of transparency, expression of floating status, changeable image, illusion effect, blurring boundary. Immateriality is deeply associated with the elements such as surface, material, media, light, and movement. So it is being recognized as an important design concept in today's pluralist society and will play an important role within the design paradigms for the future.

This study aims to help users to have a more satisfying encounter based on the problems found by comparing and analyzing similar applications. That is, an application that derives intermediate points through the subway, which is a public transportation means, and provides information on nearby convenience facilities was proposed. The middle point calculation process uses the dijkstra algorithm, which stores the minimum number of nodes in the stored path from the first input location to the last location. The stack and arraylist are used to search all paths from the first input position to the last position, and then the path with the smallest number of nodes is selected. After that, the number of stations in the route is divided in half and the resulting station is output. In addition, this study provides information on convenience facilities near intermediate points in order to have differences from similar applications. It categorizes within a 1km radius of the point and provides a function that helps to conveniently identify only facilities around the middle point. In particular, by visualizing the number of convenience facilities with radar charts and numbers, it is possible to grasp the commercial district around the midpoint at a glance.

수경재배의 폐암면 처리문제를 해결하고 수입의존도가 높은 육묘용 상토 자재의 개발로 육묘산엽의 발전에 기여하고자 폐암면의 혼합비율을 달리한 플러그용 육묘상토를 조성하여 메리골드의 생육에 대한 효과를 조사하였다. 시판 육묘상토를 대조구로 하고, 시판 육묘상토에 이용되는 코코피트 대신에 폐암면을 10, 30, 50%로 혼합하여 혼합상토를 조제하여 50공 트레이에 파종하고 생육조사를 실시하였다. 메리골드의 발아율은 처리구간에 유의한 차이를 나타내지 않았다. 초장, 엽수, 경경, 엽면적과 지상부 및 지하부의 건물중 및 생체중은 시판상토와 폐암면 50% 혼합 처리구에서 양호하였다. 그러나 폐암면 30 및 10% 혼합처리구에서는 시판상토에 비해서 생육이 낮았는데 그 결과에 대해서는 정확한 원인을 밝힐 수 없었다. 본 실험에서는 폐암면을 플러그용 육묘상토의 자재로서 충분히 활용할 수 있다는 가능성을 보여 주었으며, 폐암면의 적정한 혼합비율에 대해서는 계속적인 실험이 필요한 것으로 생각되었다.

Objective: Optimizing culture media for the incubation of immature oocytes is a vital strategy to increase the oocyte maturation rate during in vitro maturation (IVM) programs. This study evaluated the IVM and fertilization rates of human germinal vesicle (GV) and metaphase I (MI) oocytes using two different maturation media (commercial and homemade) with or without growth differentiation factor 9-β (GDF9-β). supplementation. Methods: Immature oocytes from intracytoplasmic sperm injection (ICSI) cycles were collected and assigned to one of two IVM culture media (commercial or homemade; cleavage-stage base). After maturation, MII oocytes were examined under an inverted microscope for the presence of the polar body, zona pellucida (ZP) birefringence, and meiotic spindle (MS) visualization after maturation in four conditions (commercial or homemade medium, with or without GDF9-β. ICSI was done for matured oocytes, and fertilization was confirmed by the visualization of two distinct pronuclei and two polar bodies. Results: No significant differences were found between the two culture media in terms of the time and rate of oocyte maturation or the rate of fertilization (p>0.05). Growth factor supplementation increased the 24-hour maturation rate for both GV and MI oocytes only in homemade medium. The maturation rate after 24 hours was higher for MI oocytes (p<0.05). Similar results were observed for MS visualization and ZP structure in both types of media (p>0.05). Conclusion: Higher rates of oocyte maturation and fertilization were observed after application of homemade medium supplemented with GDF9-β. Therefore, this combination may be recommended as an alternative for clinical IVM programs.

All vague and constructions of contemporary cultural environment have been reorganized and the relationship between people and culture can't follow development speed of rapid material civilization development and being informationalized. Because of the circumstances, physical environment is changing into other cultural environment, existence of human being is at a crisis. Physical value precedes mental value and rapid changing causes culture lag. Modernism design of 20th century suggested standard, simplicity and mass production methods, but nowaday, as human being complexity is increasing, information-media are needed to satisfy that. Namely usual design thoughts have to be changed because our life is surrounded by many kinds of powerful media sings and various mixed cultural circumstances. People predict that the characteristics of new ages are 'Immateriality', 'Sensoriality', 'multimedia'. Amongst them, medial spatial characteristics will be eventually remarkable in commercial space which is coincided with economic logic and multilateral culture. This study is a focus on commercial space which emphasis contemporary medial characteristics and observes medial meaning and various technique through some experimental works in Korea. Also this study's purpose is to examine design directions which correspond with contemporary Korea culture.

Objectives: The purpose of this present study was to compare mouse embryo development in 3 commercial media and hatching competence of mouse embryo with or without enzymatic treatment. Methods: Collected 375 mouse embryos were divided into three groups, and then cultured in IVF-20 (G2), Medicult IVF (M3), P-1 (blastocyst M), respectively. Three day mouse morulae were cultured in G2 media treated with pronase. The results were analyzed using Chi-square test, and considered statistically significant when p<0.01. Results: The developmental rate of 2 cell mouse embryo after 72 hours was highest in IVF-20 (G2) among conventional 3 media. The hatching rate of mouse morulae was low when clultured in G2 media without pronase during 48 hours. However, it was higher when cultured in media treated with $1{\mu}g/ml$, $2.5{\mu}g/ml$, $5{\mu}g/ml$ pronase, respectively. Conclusions: Using good media and digestion of zona pellucida with enzymatic treatment improve development and hatching rate of embryo. Therefore, implantation and pregnancy rate could be improved.
