Use of the cast net for monitoring fish status in reservoirs distributed in the Korean peninsula
장민호,Ju-Duk Yoon,김정희,Hae-Jin Lee 한국생태학회 2015 Journal of Ecology and Environment Vol.38 No.3
Reservoirs consist of two different environments, the littoral and the pelagic zone, and different fishing gear is commonly used in each zone—gill nets in the pelagic zone and electrofishing in the littoral zone. However, an active fishing gear, the cast net, is normally used instead of electrofishing for scientific studies in South Korea. In order to estimate cast net effectiveness for determining fish status in reservoirs, the study was conducted at 15 reservoirs with two different fishing gears: a cast net in the littoral zone and gill nets in the pelagic zone. When combining catches of both gears, species richness increased substantially compared to using one gear only. There was a size difference in fish caught by each net, and small fish were predominantly caught with the cast net due to its small mesh size (7 mm). The combined length of six species, used for length-weight relationship analysis, collected with the cast net was smaller than that collected with gill nets (independent t-test, P < 0.05). In this study, cast net sampling provided sufficient data for the littoral zone, but not enough to identify the overall fish assemblage in studied reservoirs. Utilization of only one gear can therefore lead to substantial underestimation of fish status, and a combination of both gears is recommended for determining more reliable estimates of fish status in reservoirs.
국내 주요사찰 안내판의 번역에 나타난 TT의 양적 변화 분석
장민호 한국통번역교육학회 2010 통번역교육연구 Vol.8 No.1
The purpose of this study is to determine whether TTs in temple information boards are shorter than those of typical Korean-English translations and to explore its causes. Ten of Korea's major temples are selected as the sample. The findings show that the average expansion rate of temple information TTs is 1.93, much higher than that of average Korean-English translations. The main reason behind this high expansion rate is that translators of temple information boards apply reduction techniques less often to their versions than in other types of translations. Based on the study findings this study proposes a more active role played by relevant authorities in making information boards more readable and thus more interesting.
장민호 한국통역번역학회 2009 통역과 번역 Vol.11 No.1
The purpose of this study is to examine how subtitlers work to make their translation more visually convincing. Audio-visual translation, or subtitling, is not a verbal-only activity. It involves various channels of information: verbal visual, verbal auditory, non-verbal auditory, and non-verbal visual. Research so far has been focused on how subtitlers make their versions shorter to increase readability for viewers, and what messages could be lost during the process. For one specific Hollywood movie which involves two languages, this study looks at how subtitles convey additional information and at what techniques are used. This paper will provide some insights into why subtitling is not only about making shorter TTs and how important the translator intervention is, and how translators combine language and image into their version to maximize entertaining elements of movies. Lost in Translation shows what could also be added in translation.
동물플랑크톤 노출 강도가 유해남조 Microcystis aeruginosa와 Planktothrix agardhii의 생체량 및 세포내 microcystin함량변화에 미치는 영향
장민호,정종문,주기재 한국하천호수학회 2006 생태와 환경 Vol.39 No.2
This study was to evaluate microcystin production by two strains of cyanobacteria (Microcystis aeruginosa and Planktothrix agardhii) in response to three different levels of direct (0, 4, 8 inds.) or indirect (0, 25, 50% of zooplankton culture media filtrate) exposures to zooplankton (Daphnia magna and Moina macrocopa). The cell biomass and intracellular microcystin (MC) were measured everyday. The survival rates of zooplankton were evaluated for daily intervals for the direct exposure. The intracellular MC produced peaked on the day 3 or 4, and then decreased over the both exposure experiment. In the direct experiment, the MC values were significantly different among the control and zooplankton treatments (ZT; repeated measures- ANOVA: P⁄0.039). The MC contents of P. agardhii strain (No. 204) were significantly higher (Tukey test, P⁄0.082) in ZT2 (8 inds.) than in ZT1 (4 inds.). On the peak day, the intracellular MC exposed to both zooplanktons was significantly higher than the control (One-way ANOVA, P⁄0.021). Higher zooplankton survivals were observed in the M. aeruginosa strain (No. 111) rather than in high toxic P. agardhii strain. In the indirect experiment, the intracellular MC of the M. aeruginosa strain was significantly different among the control and zooplankton culture media filtrate (ZCMF) treatments (rm-ANOVA: P⁄0.004). The MC exposed ZCMF2 (50%) were significantly higher than in ZCMF1 (25%; Tukey test, P⁄0.025) for both strains. This study strongly supports the induced-defensive MC production of potentially toxic cyanobacteria in response to the presence of zooplankton.
K<sup>+</sup>-β/β"-Al<sub>2</sub>O<sub>3</sub>의 고온 상관계와 소결성 분석
장민호,김승균,김석준,허정림,임성기,Jang, Min-Ho,Kim, Seung-Gyun,Kim, Seok-Jun,Haw, Jung-Rim,Lim, Sung-Ki 한국공업화학회 2009 공업화학 Vol.20 No.3
고체 산화물 전해질로 사용되고 있는 초 이온 전도체인 $K^+-{\beta}/{\beta}"-Al_2O_3$의 고온 상관계와 소결성 분석을 위하여 $K_2O-LiO_2-Al_2O_3$ 삼성분계로부터 고상반응을 통하여 순수한 $K^+-{\beta}/{\beta}"-Al_2O_3$ 분말을 합성한 후 slip casting방법과 냉간정수압성형에 의하여 tube와 disk형을 각각 제작하였다. Slip casting은 40 wt%의 고체함량을 가지는 슬러리를 사용해 알루미나 몰드에서 이루어졌고 냉간정수압성형은 20 MPa의 압력하에서 수행되었다. 성형체들은 $1600^{\circ}C$, $1700^{\circ}C$, $1750^{\circ}C$에서 각각 소결하여 성형방법에 따른 상관계와 소결밀도를 조사하였다. 냉간정수압성형에 의한 시편이 $1700^{\circ}C$까지 ${\beta}"-Al_2O_3$의 상분율이 월등히 높은 반면, 소결밀도에 있어서는 slip casting방법의 경우가 다소 높았다. 소결 시 상대밀도는 $1750^{\circ}C$에서 1 h 경과 후, 두 경우 모두 약 83%를 나타내었다. 90 min 이상 소결하였을 때는 입자의 과대성장과 기공으로 인해 오히려 밀도가 낮아졌다. In order to analyze the high temperature phase formation and the sinterability of super ionic conductor $K^+-{\beta}/{\beta}"-Al_2O_3$ which is commonly used as a solid oxide electrolyte, the pure $K^+-{\beta}/{\beta}"-Al_2O_3$ powder in the ternary system $K_2O-LiO_2-Al_2O_3$ was synthesized by solid state reaction and formed to tube and disk using slip casting method and cold isostatic pressing (CIP), respectively. The slip casting was conducted in an alumina mold with the slurry containing 40 wt% of solid contents and the CIP was carried out under 20 MPa. The samples were sintered at $1600^{\circ}C$, $1700^{\circ}C$ and $1750^{\circ}C$, respectively, and their phase formation and the sintering density were investigated according to the forming method. The samples produced by CIP showed far higher ${\beta}"-Al_2O_3$ fraction as compared with those by slip casting. On the other hand, the samples by slip casting showed slightly higher sintering density. The relative density reached to about 83% at $1750^{\circ}C$ and for 1 h, independent of the forming method. In the case of 90 min socking time, the density was decreased owing to the exaggerated grain growth and the pores by $K_2O$ evaporation.
