이 글은 두 가지 비판적 탐색과 이를 통한 비평의 확장을 시도하고 있다. 첫째는 중국 고전 텍스트에 대한 루쉰의 사유와 연구태도를 살펴보고, 아울러 루쉰이 '예악'을 어떻게 비판적으로 성찰하고 있는지를 탐색해 본다. 《광인일기》의 광인이 중국의 오래된 텍스트를 다루는 방식을 실마리로 삼아, 루쉰의 중국 고전 문헌의 편집과 전승과정을 비판적으로 성찰하는태도를 살펴보았다. 루쉰은 고전 문헌이 역사 속에서 전승·전파될 때, 텍스트가 편집 재구성되는 가운데 사건과 맥락, 실재가 은폐되고 텍스트가 봉쇄되는 상황을 주목한다. 또한 루쉰은텍스트의 전승과정과 아울러 중국문화와 사회·정치의 구성에 '예악'이라는 오래된 문화가 어떻게 작동하며 현재에도 어떻게 영향을 미치는지를 비판적으로 성찰하고 있다. 고전은 단순히 과거가 아니라 현재의 습속과 도덕 감정, 그리고 통치성과도 밀접하게 연결되어 있다. 둘째, 이러한 루쉰의 예악에 대한 성찰을 바탕으로 루쉰이 평생에 걸쳐 교감했던 혜강(嵇康)의 글 중<성무애락론>을 중심으로 그의 미완의 고전비평의 가능성을 탐색한다. '소리에는 슬픔과 기쁨이 없다'는 혜강의 이 글은 중국문화구성의 핵심 논리인 '예악'의 문제에 대해 깊이 있게 성찰한 것으로, 감응주체의 자율성, 그리고 조화로움, 공통적인 것을 찾아가는 개체의 숙고 과정을 중시하며 기존 예악과 통치성의 문제에 균열을 낸다. 루쉰을 통해 혜강을, 혜강을 통해루쉰을 살펴보는 작업을 통해 루쉰의 못 다한 고전비평의 작업을 재구성하고, 중국고전텍스트가 현재의 실제 삶과 접속될 가능성을 탐색해 본다.

Fish are an essential resource in human society, and while ecological research on them is challenging, it is absolutely necessary. Recent technologies enabled researchers to monitor underwater fish behavior. Acoustic signals, satellite-mediated location estimation, and light-based geolocation are powerful tools for tracking fish movements from freshwater to deep-sea habitats. These tools allow us to track various fish species and elucidate their ecology. Furthermore, based on these technologies, we can develop fisheries management plans and enhance aquaculture productivity. In this review, we also discuss challenges in improving current technologies and provide future recommendations for fish bio-logging studies.

In a recent study by the same authors using a DMTA (Dynamic Mechanical Thermal Analyzer), it was found that the 4-aminobenzoic arid (ABA) molecules acted as either a neutralizing agent, or a plasticizer, or a filler, depending on the order of mixing of poly(styrene-co-styrenesulfonic acid) (PSSA), ABA, and NaOH. Subsequent to that study, we here pursued the same topic, i.e., the effect of the addition of CsOH (instead of NaOH) and ABA on the morphology of PSSA, but this time, by using a small-angle X-ray scattering (SAXS) technique. In line with the previous results, the present study with the SAXS technique verified that the order of mixing has a significant effect on the morphology of ionomers. In addition, with the SAXS data and the density values of the ionomers, we attempted to calculate both the number of sulfonate ionic groups per multiplet and the size of the multiplet of the ionomer.

The bio-logging method could be a valuable approach to studying the underwater movement of marine fish. We investigated the horizontal and vertical movement patterns of two yellowtails Seriola quinqueradiata weighing 8.7 kg and 9.5 kg with a popup satellite archival tag from October 2020 to January 2021 in the East Sea of Korea. Our results showed that a yellowtail migrated northward in October and November, and then shifted southward in mid-December. The average swimming depth and temperature of the fish monitored over 82 days were 24.9 ± 9.3 m (average ± SD) and 16.5 ± 1.9℃, respectively, and the total traveled distance was 1,172.4 km. The fish swam significantly deeper during the daytime (33.70 ± 14.80 m) than at nighttime (20.65 ± 8.44 m) from November to December (p < 0.05). These results suggest that the horizontal migratory route of yellowtails in accordance with the East Korea Warm Current which is the main branch of Tsushima Warm Current in the fall and early winter seasons, and showed significant diel vertical movement patterns from November to December.

1,4-Naphthoquinones are widely distributed in nature and many clinically important antitumor drugs containing a quinone moiety, such as anthracyclines, mitoxantrones and saintopin, show excellent anticancer activity. In this study, 2- or 6-substituted 5,8-dimethoxy-1,4-naphthoquinone (DMNQ) and 5,8-dihydroxy-1,4-naphthoquinone (DHNQ) derivatives were synthesized, and their cytotoxic activity against L1210 and P388 cancer cells was examined. Their antitumor activity was also assessed in mice bearing S-180 cells in the peritoneal cavity. In comparison with the DMNQ derivatives, the DHNQ derivatives exhibited more potent bioactivities than the DMNQ derivatives against both L1210 and P388 cells in vitro and S-180 cells in vivo. The $ED_{50}$ values of the DHNQ derivatives against P388 cells were in the range of 0.18-1.81 ${\mu}g/mL$ whereas those of the DMNQ derivatives were in the range of 0.26-40.41 ${\mu}g/mL$. The T/C ($\%$) values of the DHNQ derivatives, 8, 17, 18, 19, and 20, were found to be comparable to or even better than that of adriamycin. It was also observed that the 2-substituted derivatives (8, 19, 20) showed better antitumor activity than the 6-substituted derivatives (7, 17, 18) in the mice bearing S-180 cells in the peritoneal cavity.
