Most of the unused facility in urban areas is perceived as an unreasonable space that damages cityscapes. However, unused space has the advantage of having historical value and potential for new development. In consideration of this, various plans have recently been made in terms of cultural use of unused space. The core is the performing arts culture space where various expressions can be expressed. Changes in the educational space that meet the various conditions required in future societies are also one of the topics to be discussed. In this study, we analyze the performance facilities utilizing the unused space and study the direction of educational facilities based on performance.

Composition of the Phytoplankton Pigments in the Surface Waters Along a Transect from the Northwestern to the Southeastern Pacific Ocean

윤원덕,이용화,김향임 한국해양과학기술원 2009 Ocean science journal Vol.44 No.2

Multidisciplinary oceanic investigation was undertaken in Aug - Sep. 2003 along a transect from Northwestern (Busan, Korea) to Southeastern Pacific (Talcahuano, Chile) to understand the physical, chemical and biological features in the surface water, and to depict their interaction with the atmosphere. Among the twenty parameters measured, we describe the physical, chemical and biological features. Physico-chemical data were analyzed in conjunction with the geographic position and yielded 7 peculiar surface water masses. The first water mass (28.4˚N, 130.8˚E to 21.5˚N, 139.5˚E) was warm and low in phosphate and nitrate content, and high in silicate. The concentration of phytoplankton pigment was one of the lowest. The second (20.4˚N, 140.7˚E to 2.2˚S, 162.9˚E) was the warmest and the least saline. Nitrate and phosphate concentration were one of the lowest. Chlorophyll a (Chl a) concentration was the lowest among the surface waters. The third (3.4˚S, 164.0˚E to 14.5˚S, 173.3˚E) was warm. Nitrate concentration was the lowest. CHL-a, peridinin (Perid), violaxanthin (Viola), zeaxanthin (Zea), chlorophyll-b (Chl b) and β-CAR were abundant. The fourth (18.6˚S, 177.5˚E to 31.8˚S, 123.9˚W) was saline and poor in nutrient concentration. The contributions of 19'-butanoyloxyfucoxanthin (But-fuco), 19'-hexanoyloxyfucoxanthin (Hex-fuco), and CHL b to CHL a were non-negligible. The fifth (32.4˚S, 122.1˚W to 33.8˚S, 117.2˚W) was relatively cold and well oxygenated. Concentration of Fuco, But-fuco, Hex-fuco and Chl b was high. The sixth (34.2˚S, 115.4˚W to 37.4˚S, 92.1˚W) was cold, well oxygenated and enriched with phosphate and nitrate. Concentration of phytoplankton pigment was, however, one of the lowest. The seventh, located off the Chilean coast, from 37.2˚S, 87.2˚W to 36.1˚S, 74.1˚W was well oxygenated and highly enriched with nitrate and phosphate. Phytoplankton pigments such as Fuco, Perid, But-fico, and Hex-fuco were rich. The 7 surface water masses are partially attributed to Kuroshio Current, North Equatorial Current and North Equatorial Countercurrent, South Equatorial current, South Pacific Subtropical Gyre, South Pacific Current, Subtropical Front and Chilean coastal water. The differences in physicochemical characteristics and the history of the surface water resulted in difference in quantity and composition of the phytoplankton pigment.

Then, it analyzes the spatial composition and the stage form of "Space Nine", "Hanghwa Tang", "Shinchon Theater", and "Miarigogae Art Theater" using unused space in Seoul city. These, this study investigate what elements of unused space can be utilized as a small theater by collecting the components of each theater.

First Record of Box Jellyfish, Carybdea brevipedalia (Cnidaria: Cubozoa: Carybdeidae) from Korean Coastal Waters: Morphology and Molecular Descriptions

채진호,윤원덕,김병호,기장서 한국동물분류학회 2017 Animal Systematics, Evolution and Diversity Vol.33 No.1

We firstly described a box jellyfish, Carybdea brevipedalia collected from the southern coasts of Korea. It is morphologically characterized by gastric phacellae, a special digestive system of cubozoan jellyfish, and velarium, the thin muscle flap forming the opening of the subumbrellar cavity. The phacellae are linear-shaped, comprising numerous cirri branched from multiple roots. Each root also has multiple numbers of cirrus bundles. Basis of velarial cannels parts into two branches in each octant of velarium. Its geographic distributions were limited to Jejudo and the middle-southern coasts where the organisms are seriously hazardous to bathers in summer. Numerous individuals and/or large-sized populations were observed specifically from beaches at Jeju-do, Namhae-do and a small fishing port of Namildae, while only a small amount of the individuals was observed in Gamak Bay, Jaran- Goseung Bay, and Geoje-do. We confirmed molecular identity of the Korean C. brevipedalia with comparison of nuclear ribosomal DNA sequences. Until now, Carybdea brevipedalia is the only cubozoan species reported to be distributed in Korean waters.

First Record of Two Cold-Water Jellyfishes Aurelia limbata and Parumbrosa polylobata (Scyphozoa: Semaeostomeae: Ulmaridae) in Korean Coastal Waters

장수정,김정년,윤원덕,기장서 한국동물분류학회 2016 Animal Systematics, Evolution and Diversity Vol.32 No.4

Most scyphomedusae jellyfishes recorded in Korean waters are temperate and subtropical species. In the present study, two cold-water jellyfishes from Korean waters are first described. Scyphomedusae were collected from the coasts of Gangneung and Ulsan of the East Sea, and Boryeong, and the eastern area of the Yellow Sea from June 2006 to May 2015. Scyphomedusae collected in Ulsan and Gangneung were identified morphologically as Aurelia limbata Brandt, 1835. Their umbrella was 250-500 mm in width and 30-50 mm in height; the exumbrella was white and the subumbrella was dark brown in color. The vascular system was complex with anastomosed branches. Individuals of this species lived at about 6.6-9.9°C and 30-50 m depth in Korean waters. Scyphomedusae collected from the center of the Yellow Sea and from Boryeong were identified as Parumbrosa polylobata Kishinouye, 1910. Their umbrella was disc-shaped, 80-200 mm in width and 20-40 mm in height. Its milky white gonads could be seen through the transparent exumbrella. The stomach cavity was round and flat with four interradial cavities connected by subgenital cavities, and the four oral arms were bifurcated and spear-head shaped. Individuals were found at about 6.4-10.0°C and 40-90 m depth in Korean waters. The identities of both species were confirmed by molecular analysis using nuclear ribosomal DNA sequences.

Behavior and frequency analysis of Aurelia aurita by using in situ target strength at a port in southwestern Korea

윤은아,황두진,윤원덕,이경훈 한국해양과학기술원 2018 Ocean science journal Vol.53 No.1

This study was carried out to determine the in situ target strength and behavioral characteristics of moon jellyfish (Aurelia aurita) using two frequencies (38 and 120 kHz) that present a 2- frequency-difference method for distinguishing A. aurita from other marine planktonic organisms. The average TS was shown as -71.9~ -67.9 dB at 38 kHz and -75.5~-66.0 dB at 120 kHz and the average ΔMVBS120-38 kHz was similar at -1.5~3.5 dB. The TS values varied in a range of about 14 dB from -83.3 and -69.0 dB depending on the pulsation of A. aurita. The species moved in a range of -0.1~1.0 m and they mostly moved horizontally with moving speeds of 0.3~0.6 m·s-1. The TS and behavioral characteristics of A. aurita can distinguish the species from others. The acoustic technology can also contribute to understanding the distribution and abundance of the species.

Density Estimates of Moon Jellyfish (Aurelia coerulea) in the Yeongsan Estuary Using Nets and Hydroacoustics

윤은아,이경훈,채진호,윤원덕,한창훈,이혜은,김병관,오우석 한국해양과학기술원 2019 Ocean science journal Vol.54 No.3

Using nets and acoustic frequencies of 38 and 120 kHz, we estimated the density distribution of the moon jellyfish, Aurelia coerulea, in the Yeongsan Estuary, where a large bloom was detected. Aurelia aurita captured in nets had bell diameters of 3.2–22.0 cm and wet weights of 2.0–265.0 g, and the relationship between wet weight (W) and bell diameter (BD) was W = 0.1284BD2.5263 (R2 = 0.92). We examined the target strength (TS) difference (120–38 kHz) using a theoretical acoustic scatter model and found that the TS difference ranged from -1.5 to 2.2 dB when the bell diameter was the smallest during underwater pulsation, and from -1.4 to 1.7 dB when the bell diameter was the largest. Based on frequency differences, we found that the mean nautical area scattering coefficient (NASC) of A. coerulea for transects was in the range of 16.4 to 167.0 m2/nm2. In nets near the Yeongsan River Barrier and to its south, jellyfish were caught at a high density of 5.5 ind./m2. The mean density of A. coerulea measured using acoustic methods and nets was 0.16 ind./m2 and 2.02 ind./m3, respectively.

Reproduction of the giant jellyfish, Nemopilema nomurai (Scyphozoa: Rhizostomeae), in 2006-2008 as peripherally-transported populations

Naoki Iguchi,이혜은,윤원덕,김수암 한국해양과학기술원 2010 Ocean science journal Vol.45 No.2

This study investigated the sexual maturation process, release of spermatozoa or eggs and oocyte diameter of the rhizostomid medusae Nemopilema nomurai using samples collected from August 2006 to June 2008 from the waters around Korea and Japan, including peripheral areas outside the species’ usual habitat. Immature medusae were observed from June to October only in the western sector of the study area. The onset of spermatozoa and egg release occurred in September and October, respectively, and peaked in December and January. Medusae migrated eastward from source areas with the Tsushima Warm Current, where they formed gametes and spawned. Peak position and maximum oocyte diameter increased as the gonads developed according to the size-frequency distribution of oocytes. No fertilized eggs or embryos were found in the gonads. The correlation was analyzed with bell diameter, maximum oocyte diameter, sampling date, surface water temperature and gonad color to estimate which environmental factors and maturation indices were related to the maturation stage of females. Maturation stage correlated well with maximum oocyte diameter, which correlated negatively with surface water temperature. There was no significant correlation between bell diameter and maturation stage. Therefore, bell diameter was inappropriate for determining maturation index. Sex could not be distinguished clearly by gonad color. However, light pink gonads were more prevalent in males and various deep colors such as orange and brown were more frequent in female medusae.

Re-description of Chrysaora pacifica (Goette, 1886) (Cnidaria, Scyphozoa) from Korean Coastal Waters: Morphology and Molecular Comparisons

Hye Eun Lee,윤원덕,채진호,기장서 한국해양과학기술원 2016 Ocean and Polar Research Vol.38 No.4

The nomenclature of the sea nettle jellyfish from Korea was initially described as Dactylometra quinquecirrha Agassiz, 1862. However its identity has been questioned on the basis of its local distribution and molecular data. Here, we examined morphology and DNA sequences of nuclear rDNA using specimens collected from southern Korean waters in August 2014. Based on morphological characteristics (bell size, umbrella pattern, number of tentacles and lappets) and distribution locality, we reassign the Korean D.quinquecirrha to Chrysaora pacifica (Goette, 1886), and provide a re-description accordingly. The molecular identity of C. pacifica was further confirmed by comparison of nuclear ribosomal DNA sequences.
