  • In the autumn of 2000 and spring of 2001, field surveys were conducted to estimate the effectiveness of artificial reefs (type cube, $2{\times}2{\times}2m^3$) that were established in the four islands of Bangnyeong, Socheong, Daeyeonpyeong and Ganghwa in Kyonggi Bay, the west coast of Korea during 1995 and 1996. The condition of reefs was examined through SCUBA diving and a side-scan sonar. Much of the reefs in Daeyeonpyeong and Ganghwa area were buried in bottom sediment. Despite an intensive search in Bangnyeong area, even a cluster of reefs was not found and most of them seemed to be buried by sand waves. Thus an appropriate investigation on the sediment transport should be included in pre-assessment for the expected performance and protection of artificial reefs. Distribution of average CPUE in natural fishing ground (control) was estimated by bootstrapping simulation and possible comparison of CPUE between control and reef areas (treatment) were made in Bangnyeong and Socheong (Experiment I). Positive reef effect was detected in Socheong but CPUE of treatment in Bangnyeong was varied between or lower than the 99% CPUE confidence intervals of the control. Control/treatment abundance and biomass of fishes and invertebrates were tested by paired t-test and sign test (Experiment II). Only four cases among 22 showed significant positive effect. Based on the results, the cube artificial reef in Socheong was inferred as an affirmative one. Floor type was hypothesized to be one of the probable agents in determining the effectiveness of artificial reefs.

  • Inflammatory response and oxidative stress play critical roles in the development and progression of many human diseases. Therefore, a great deal of attention has been focused on finding functional materials that can control inflammation and oxidative stress simultaneously. The purpose of this study was to investigate the effects of Socheongja and Socheong 2, Korean black seed coat soybean varieties, on the inflammatory and oxidative stress induced by lipopolysaccharide (LPS) in RAW 264.7 macrophages. Our data indicated that the extracts of Socheongja (SCJ) and Socheong 2 (SC2) significantly suppressed LPS-induced production of nitrite oxide (NO) and prostaglandin $E_2$, key pro-inflammatory mediators, by suppressing the expression of inducible NO synthase and cyclooxygenase-2. It was also found that SCJ and SC2 reduced the LPS-induced secretion of pro-inflammatory cytokines, such as tumor necrosis $factor-{\alpha}$ and $interleukin-1{\beta}$, which was concomitant with a decrease in the protein levels. In addition, SCJ and SC2 markedly diminished LPS-stimulated intracellular reactive oxygen species accumulation, and effectively enhanced nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase (HO)-1 expression. Furthermore, LPS-induced activation of mitogen-activated protein kinases (MAPKs) was abrogated by SCJ and SC2. Taken together, these data suggest that SCJ and SC2 may offer protective roles against LPS-induced inflammatory and oxidative responses in RAW 264.7 macrophages through attenuating MAPKs pathway, and these effects are mediated, at least in part, through activating Nrf2/HO-1 pathway. Given these results, we propose that SCJ and SC2 have therapeutic potential in the treatment of inflammatory and oxidative disorders caused by over-activation of macrophages.

  • Proximate compositions, quality and physicochemical characteristics of small black soybean cultivar, cultivated in the north-central region of South Korea with different seeding periods, were evaluated. Proximate compositions, chromaticity, water binding capacity, water solubility index, swelling power, and antioxidant properties were significantly different among cultivars and different seeding periods. Moisture, crude ash, fat, protein, and carbohydrate contents of small black soybean cultivar were 5.53~6.69, 5.47~6.54, 15.38~19.14, 34.17~40.26, and 32.04~36.85 g/100 g, respectively. Lightness, redness and yellowness were 35.60~38.61, -0.02~0.07 and -0.56~-0.13, and water binding capacity, water solubility index and swelling power were 84.48~148.31, 46.65~54.89 and 29.87~35.12%, respectively. Total polyphenol contents of first, second, and third seedings on small black soybean cultivar were 10.40~15.48, 9.86~14.85 and 8.61~15.39 mg GAE/g; total flavonoid contents were 5.81~7.25, 5.81~7.34 and 5.52~7.64 mg CE/g, respectively. DPPH radical scavenging activity was 4.55~7.86, 3.99~8.79, and 3.74~9.43 mg TE/g, and ABTS radical scavenging activity was 9.32~12.90, 8.64~13.39, and 8.51~14.35 mg TE/g, respectively. Phenol compound of Tawonkong and Socheong cultivars decreased with delay of seeding periods. Radical scavenging activity of Socheong and Jununi cultivars decreased with delay of seeding periods, but Socheong 2 and Socheongja cultivars increased. In the study, phenol compound and radical scavenging activity of small black soybean cultivar were different, depending on cultivars and seeding periods.

  • Black soybeans are used as food sources as well as for traditional medicines because they contain an abundance of natural phenolic compounds. In this study, total phenolic contents (TPCs) of Korean black seed coat soybean varieties Socheongja (SCJ), Socheong 2 (SC2) and Cheongja 2 (CJ2) as well as their antioxidant capacities were investigated. Among them, TPCs were abundantly present in the order of CJ2$H_2O_2$-stimulated HaCaT human keratinocytes. Our results revealed that treatment with SCJ and SC2 prior to $H_2O_2$ exposure significantly increases the viability of HaCaT cells, indicating that the exposure of HaCaT cells to SCJ and SC2 conferred a protective effect against oxidative stress. SCJ and SC2 also effectively inhibited $H_2O_2$-induced apoptotic cell death through the blocking of mitochondrial dysfunction. SCJ and SC2 also attenuated the phosphorylation of Histone H2AX. Furthermore, they effectively induced the levels of thioredoxin reductase (TrxR) 1, a potent antioxidant enzyme, which is associated with the induction of nuclear transcription factor erythroid-2-like factor 2 (Nrf2); however, the protective effects of SCJ and SC2 were significantly reversed by Auranofin, a TrxR inhibitor. These results indicate that they have protective activity through the blocking of cellular damage related to oxidative stress via the Nrf2 signaling pathway. In conclusion, our study indicated that SCJ and SC2 might potentially serve as novel agents for the treatment and prevention of skin disorders caused by oxidative stress.

  • Cardot(1904) first reported 98 Korean mosses, which were collected from Busan, Gangwon Province, Mokpo, Seoul, Wonsan and Pyongyang by Father Faurie in 1901. Thirty-four of these species were new species to the world. However, eight of these species have been not listed to the moss checklist of Korea before this study. Thus, this study complies the literature including Korean mosses, and lists all the species there. As the result, the moss list of Korea is updated as including 775 taxa (728 species, 7 subspecies, 38 varieties, 2 forma) arranged into 56 families and 250 genera. This list include species that have been newly recorded since 1980. Brachythecium is the largest genus in Korea, and Fissidens, Sphagnum, Dicranum and Entodon are relatively large. Additionally, this study cites specimens collected from Jeju Island, Samcheok, Gangwon Province, and Socheong Island, and it is possible to confirm the distribution of 338 species in Korea.
