Outdoor cultivation of cyanobacterium Spirulina platensis was carried out for 40 days in a batch mode. A half concentration of the SOT based on the underground water was used as culture medium. Working volume was 5.7 tons with 0.2 m depth. During cultivation, mean water temperature, DO and light intensity were all in proper conditions for the S. platensis growth. The adjustment of pH to over 10 with Na2CO3 and addition of the 1.5% natural salt were very effective to delete contaminant organisms, Chlamydomonas moewusii and Chlorella minutissima occurred one after the other in the culture. The mean productivity of the biomass based on the dry cell weight from 14 to 25 days, after the contaminants were deleted, was 7.8 g ·m–2· d–1, which was relatively high productivity in that a half concentration of the SOT was used for the culture. Underground water used in the culture minimized contaminants invasion and addition of the 1.5% natural salt was effective to delete contaminants as well as acted as mineral supplement in outdoor cultivation of S. platensis. Harvesting using the floating activity of S. platensis was effective from mass floating in day time after overnight without agitation and illumination.

본 연구는 미디어 플랫폼을 기반으로 대중화를 시도하고 있는 국내 무용계의 현상을 살펴보고 이를 문화 참여자들의 상호작용을 기반으로 고찰한다. 이는 무용의 대중화는 궁극적으로 무엇을 의미하는가? 미디어를 매개로 한 대중화전략은 어떤 특징을 띄는가? 이러한 시도들은 모두 같은 속성을 지닌 대중화 전략으로 이해될 수 있는가? 라는 의문에서 비롯된 것이다. 이를 위해 무용의 대중화 전략의 주요 매개로 사용되고 있는 방송매체와 최근 주목받는 온라인 커뮤니티 플랫폼의 특성을 살펴보고, 각 매체를 중심으로 관계 맺는 문화 참여자들의 의사소통 과정에 주목한다. 이를 통해 방송매체를 매개로 한 활동은 사업가(자본)에 의해 통제되고 조종됨으로써 창작자와 수용자(시청자)의 직접적인 커뮤니케이션이 불가능해지고, 사업가가 계획한 문화상품을 생산하는 데 그침으로써 매스컬처(Mass Culture)의 성격으로 분류됨을 밝힌다. 반면 사업가의 직접적인 개입 없이 창작자와 수용자의 직접적인 의사소통 및 상호작용이 가능하며, 창작의 권리가 보장되는 성격을 지닌 온라인 커뮤니티 플랫폼은 포퓰러컬처(Popular Culture)로 분류됨으로써, 무용의 대중화에 관한 담론 확장 및 방법에 적절한 미디어 플랫폼으로 기능함을 제안한다.

The mass mortalities have been occurring of Korean scallop Patinopecten yessoensis from 1997's to now in Korea east sea. Cages behavior and interference effect (common name; curtain effect) between scallop cages were investigated in culture grounds on the eastern coastal waters of Korea for understand to mechanism of rising about mass mortalities of Korean scallop quickly. The first experiment was carried out in circulating water channel to assess inclination angel from relationship between velocity and cages interval, velocity with culture cages position. An angle of inclination of scallop culture cages were 94.6 to 92.3 degree under a several velocity which were from 0.1 m/s and 131.9 to 118.1 degree under 0.5 m/s with cages interval were 1 m, 94.3 to 91.0 degree under velocity is 0.1 m/s and 133.2 to 122.4 degree under 0.5 m/s with cages interval were 1.5 m and 94.6 to 96.4 degree under velocity is 0.1 m/s and 131.7 to 131.8 under 0.5 m/s with cages interval were 2 m. The second experiment was designed to prove the tank test. Velocities were measured inside and outside of the scallop culture ground at eastern sea of Korea. The velocity of inside of the culture was the slowest as 0.1m/s. In this result, interference between former cage and after cage was occurred.

From the environmental aspects, primary productivity of phytoplankton plays the most improtant role in enhancement of marine culture oyster production. This study may be divided into two branches; one is estimation of maximum oyster meat production per unit facility(Carrying Capacity) under the present enviromental conditions in Kamak Bay, the other is improvement of carrying from increase of primary productivity by changing the environmental conditions that cause not ot form an unfavorable environment such as the formation of oxygen deficient water mass using the eco-hydrodynamic model. By simulation of three-dimensional hydrdynamic model and ecosystem model, the comparison between observed and computed data showed good agreement. The results of sensitivity analysis showed that phytoplankton maximum growth rate was the most important parameter for phytoplankton and dissolved oxygen. The estimation of mean primary productivity of Wonpo, Kamak, Pyongsa, and Kunnae culture grounds in Kamak Bay during culturing period were 3.73gC/$m^2$/d, 2.12gC/$m^2$/d, 1.98gC/$m^2$/d, and 1.26gC/$m^2$/d, respectively. Under condition not ot form the oxygen deficient water mass, four times increasing of pollutants loading as much as the present loading from river increased mean primary productivity of whole culture grounds to 4.02gC/$m^2$/d. Sediment N, P fluxes that allowed for 35% increasing from the present conditions increased mean primary productivity of whole culture grounds to 3.65gC/$m^2$/d. Finally, ten times increasing of boundary loadings from the present conditions increased mean primary productivity of whole culture grounds to 3.95gC/$m^2$/d. The maximum oyster meat production per year and that of unit facility in actual oyster culture grounds under the present conditions were 6,929ton and 0.93ton, respectively. This 0.93ton/unit facility is considered to be the carrying capacity in study area, and if the primary productivity is increased by changing the environmental conditions, oyster production can be increased.

This study investigated the productivity and growth of copepods, Sinocalanus tenellus 2 strains, Paracyclopina nana 3 strains, Apocyclops royi 2 strains, Tachidius triangularis 1 strain and Tigriopus sp. 1 strain at different temperatures $(24,\;28\;and\;32^{\circ}C)$ under 15 psu and various salinities (10, 20, 30 psu) at $28^{\circ}C$ for an individual culture. And the mass culture was carried out to evaluate the production of these copepods in the 500 mL vessel. For an individual culture of copepod, survival period of a brood female tended to increase with the decrease of temperature, but was not significantly influenced by salinity. With an increase of temperature and a decrease of salinity, maturation period of nauplii in all species tended to decrease. Total nauglii production from a broodo female at $24^{\circ}C$ was higoher than that from a brood .female at either 28 or $32^{\circ}C$ for S. tenellus and at $32^{\circ}C$ than either 24 or $32^{\circ}C$ for A. royi Haenam stram, but was not influenced by temperature for another copepods. And total nauplii production from a brood female at 10 and 20 psu tended to be higher than that from a brood female at 30 psu, expect for Tigriopus sp. and P. nana Hwajinpo strain. Total nauplii production from a brood female was the highest in Tigriopus sp. (350 nauplii) at $28^{\circ}C$ under 20 psu, followed by A. royi Haenam strain (187 nauplii) at $32^{\circ}C$ under 15 psu and P. nana Hwajinpo strain (152 nauplii) at $24^{\circ}C$ under 10 psu. In the mass culture of each copepod, P. nana was the most productive (26.6 mg dry weight) and this value was two and four times higher than productivity of Tigriopus sp. and A. royi, respectively.

Due to the remarkable changes in the early twentieth century, the new invention and technology impacted peoples' everyday lives and people started to use the word, modern, to apply specifically to what pertained to present times and to designate a movement in what was new and not old-fashioned-a condition of newness. In the present day, however, the fantastic cultural changes of a century ago have now become commonplace, and what was once considered radically new is no longer a reason to marvel. This paper considers what it mean to be modern, once the new is no longer new. This question seems to remain as complicated and inappropriate to ponder because the consideration and impact of modernity cannot simply end with the end of an era. This paper investigates how the interconnected nature of popular culture provides apt illustrations to reveal the ambivalent nature of modernity and postmodernity. In doing so, first of all, this paper pays attentions to the notion of modernity and popular culture which emerged together in the early twentieth century when technology and mass consumer culture were promoted over the world. Also, it examines how popular culture represents a complex of mutually-interdependent perspectives and values that influence society and its institutions in various ways as the image of modernity continues to build in a postmodern era. That is, popular culture is identified as a large amount of intertextuality or collective experiences due to its intermingling of complementary distribution sources and techonology. Thus, this paper explores that popular culture devotes itself other images or narratives instead of referring to the real world and its output revisits the contemporary or past times in other places, being a means to produce and reproduce the accumulated images of the modern which shapes ceaseless simulacra of modernity over complexities of modernity. In order to find a critical juncture of the complex networks of modernity and popular culture, this paper considers two places, Chicago and Gyeongsung in the 1920s and 1930s in which the rapid modern experience took place and the modern movement forced the two societies to join the mass consumer culture whether willingly or not. Next, this paper considers two movies released in 2002 and 2008 that exemplify the complexities of modernity in Chicago and Gyeongung of the 1920s and 30s: Chicago and Modern Boy. Both films have common themes of the 1920s and 30s such as violence, adultery, femme fatal, and criminal themes with the forms of musical, dance, drama, and romance. Through the textual analysis of both Chicago and Modern Boy, two films are compared in observing the similar and different ways in which two films deal with the theme of modernity when they are represented from the contemporary perspectives. More specifically, this paper questions how modernity is present in contemporary cultural forms such as commercial and hybrid genre films; and how these movies create a new image of modern by embodying the double coding. Ultimately, this paper aims at realizing the paradox of double edged modernity and its ongoing discourse that controls people's consciousness through the medium of popular culture.
