In this study, the effect of Goheung pomegranate extract on postmenopausal syndrome was evaluated both in vitro and in vivo in ovariectomized Sprague-Dawly (SD) rats. Sixty female SD rats were divided into six groups: sham, sham operation and distilled water; OVX, ovariectomized and distilled water; PE1, ovariectomized and pomegranate concentrate (0.75 mL/twice/d); PE2, ovariectomized and pomegranate concentrate (1.5 mL/twice/d); PE3, ovariectomized and pomegranate concentrate (2.2 mL/twice/d); and CE, ovariectomized and commercial pomegranate concentrate (2.2 mL/twice/d). Percent bone volume (bone volume/tissue volume) and trabecular thickness (Tb.Th) improved in a dose-independent manner in PE1, 2, and 3. Especially, bone mineral density was significantly improved in PE3 (P<0.05) compared to OVX. Pomegranate extract reduced body weight and visceral fat mass. High density lipoprotein cholesterol (HDL-C) level slightly increased in a dose-independent manner in the experimental group. In addition, HDL-C/total cholesterol level of PE3 significantly increased (P<0.05) compared with OVX. These results show that pomegranate concentrate improved blood lipid levels and bone metabolism in ovariectomized rats. Therefore, Goheung pomegranate concentrates are expected to improve cardiovascular and bone-related diseases in menopausal women.

We investigated marine environmental characteristics of Goheung coastal areas in August where is known to be the first outbreak site of Cochlodinium polykrikoides (hereafter C. polykrikoides) blooms, based on the oceanographic data observed from 1993 to 2013 around the Korean southern coastal waters including Eastern China Sea by National Fisheries Research and Development Institute (NFRDI). The data of NOAA/NGSST satellite images as well as numerical simulation results by Seo et al. [2013] were also used for analysis. Water temperatures at the surface and bottom layers in Goheung coast, i.e. Narodo, were $25.0^{\circ}C$ and $23.7^{\circ}C$ so that they were higher than $23.8^{\circ}C$ and $19.4^{\circ}C$ in Geoje coast where is a reference site, respectively. In addition, salinities at the surface and bottom layers in Goheung coast were 31.78 psu and 31.98 psu so that they were a little higher than 31.54 psu at the surface but a little lower than 32.79 psu at the bottom in Geoje coast, respectively. That is, the differences in water temperature or salinity between the surface and bottom layers in Goheung coast in August were not large compared to Geoje coast. This suggests that stratification in Goheung coast in August is fairly weak or may not be established. In addition, the concentrations of DIN and DIP at the surface layer were 0.068 mg/L ($4.86{\mu}M$) and 0.015 mg/L ($5.14{\mu}M$) in Goheung coast while 0.072 mg/L ($5.14{\mu}M$) and 0.01 mg/L ($0.32{\mu}M$) in Geoje coast, so they did not indicate a meaningful difference. On the other hand, when C. polykrikoides blooms, water temperature and salinity in August at the station 317-22 ($31.5^{\circ}N$, $124^{\circ}E$) of the East China Sea, where is near the mouth of Yangtze River, were $27.8^{\circ}C$ and 31.61 psu, respectively. Thus, water temperature was much higher whereas salinity was almost similar compared to Goheung coast. Furthermore, concentrations of $NO_3-N$ and $PO_4-P$ in the East China Sea in August were remarkably high compared to Goheung coast. When C. polykrikoides blooms, according to not only the image data of satellites NOAA/NGSST but also numerical experiment results by Seo et al.[2013], the freshwater out of Yangtze River was judged to clearly affect the Korean southern coastal waters. Therefore, the supply of nutrients in terms of Yangtze River may greatly contribute to the outbreak of C. polykrikoides blooms in Goheung coast in summer.

This study was carried out to provide basic data on the anion, element, chromatic and antioxidant activities of commercial dried lavers cultivated from Seocheon, Wando, Goheung and Busan in Korea. The highest concentrations of several anions ($Cl^-$, $NO_3{^-}$, $SO_4{^2-}$, and $PO_4{^3-}$ per 100 g of dried laver) were 412.00 mg in Wando, 545.90 mg in Goheung, 297.35 mg in Seocheon, and 79.70 mg in Wando, respectively. The highest concentrations of N, C, and S were 6.40%, 41.36%, and 0.98%, respectively, in dried laver cultivated from Wando. Hunter's color values were significantly high in the order of Seocheon < Goheung < Busan < Wando for lightness, Wando < Busan < Goheung < Seocheon for redness, and Goheung < Seocheon < Busan < Wando for yellowness in the dried lavers. Total phenolic content and DPPH (1,1-diphenyl-2-picryl-hydrazyl) radical scavenging activities showed highest values of 166.10 mg/100 g and 28.48%, respectively, in dried laver cultivated from Wando.

In recent years, polyphenol-rich herbs, fruits and processed foods, which are made of plant origin, have attracted much attention due to their potential health benefits. Pomegranate (Punica granatum L.) is an important source of bioactive compounds and has been used to treat diseases because of its medicinal properties. This research was focused on characterizing Korea's national cultivar and a similar product from California, USA. To evaluate their bioactive compounds and pharmacological activities, their anti-oxidation and cancer inhibition properties, as well as their organic acid and free sugar contents, were investigated. The national cultivar had low total sugar and high organic acid contents, contrary to the imported product. The results showed that the peel of national cultivar had high polyphenol and ellagic acid contents compared to imported product. The free radical scavenging capacity was evaluated via 2,2-diphenyl-1-picrylhydrazyl (DPPH) and its positive correlation with the total polyphenol contents was found. The anti-cancer activity of methanol extracts revealed growth inhibition against the prostate cancer cell. These results signify that while pomegranate, national cultivar, is more sour than the imported product, its health benefits could be excellent. Also, the polyphenol compound content of the non-edible part (such as the peel and the seed) was higher than that of the juice. Thus, it is suggested that the byproduct of the juice extraction could be potentially used in other fields such as medicine or dietary agents.

In 2018, severe diebacks have occurred on yuzu trees cultivated in Goheung, Jeonnam Province. On-farm surveys at 18 randomly selected orchards revealed the dieback incidence ranged from 7.5% to 100% with an average of 43.6%, and 56.6% of the affected yuzu trees were eventually killed. In order to find the reason for this sudden epidemic, we investigated the weather conditions that are exclusively distinct from previous years, hypothesizing that certain weather extremes might have caused the dieback epidemic on yuzu trees. Since different temperatures can cause freeze damage to plants depending on their dormancy stages, we investigated both periods when yuzu becomes hardy under deep dormancy (January-February) and when yuzu loses its cold hardiness (March-April). First, we found that daily minimum air temperatures below $-10^{\circ}C$ were recorded for 7 days in Goheung for January and February in 2018, while no occasions in 2017. In particular, there were two extreme temperature drops ($-12.6^{\circ}C$ and $-11.5^{\circ}C$) beyond the yuzu cold hardiness limit in 2018. In addition, another occasion of two sudden temperature drops to nearly $0^{\circ}C$ were occurred right after abnormally-warm-temperature-rises to $13^{\circ}C$ of daily minimum air temperatures in mid-March and early April. In conclusion, we estimated that the possible damages by several extreme freeze events during the winter of 2018 could be a major cause of severe diebacks and subsequently killed the severely affected yuzu trees.
