This study was conducted to comprehend the spatial distribution characteristics, habitats and appearances of Hydropotes inermis by using the biotope mapping in Daebudo Island, Ansan-si. The result is base data to understand status and manage potential inhabitation of Hydropotes inermis in Daebudo Island through the Maximum Entropy model. The study used 105 traces from the primary investigation and 452 traces in the secondary investigation. The biotope types were distinquished Hydropotes inermis habitats largest from the order of natural forest (15.1%), natural coast (13.7%), marshy cultivated land (12.6%), and dry cultivated land (11.7%), and from the inhabitation trace results. Hydropotes inermis appearanced biotope types were the greatest in the order of cultivated land (49.73%) > forest (18.85%) > coast (7.00%) > grassland (6.28%). Since forests in Daebudo Island have low slope and altitude, it was concluded that Hydropotes inermis would live in most of the forests. A high number of Hydropotes inermis was found to appear in areas where the grassland is formed including cultivated lands (include unused paddies and fields) and marshy grasslands, which would result in direct damage of crops. According to the Maxent modeling analysis that used location information of Hydropotes inermis, the AUC value was 0.635 based on the ROC curve. In Daebudo Island, areas with over 0.635 potential inhabitation value are distributed all over the place, and it was concluded that each population would have a different scope of influence and home range. Hydropotes inermis living in Daebudo Island have high habitat suitability mainly around the cultivated lands near the roads, but due to the bare lands and roads, it is expected that their habitats would be fragmented and damaged, which would have a direct and indirect effect in maintaining the Hydropotes inermis population. Also, considering habitat disturbance, diverse methods for reducing damage including capturing some individuals within the limit that does not disperse Hydropotes inermis population in Daebudo Island must be carried out.

The water deer, Hydropotes inermis (Cervidae), is native to China and Korea and has two subspecies of the Chinese water deer (Hydropotes inermis inermis) and Korean water deer (Hydropotes inermis argyropus). To date, only the Korean water deer has been reported in South Korea. In this study, however, an intraspecific phylogeny and haplotype analysis based on mitochondrial cytochrome oxidase I indicated that both Korean and Chinese water deer are found in South Korea. The populations of the two Korean genetic lineages did not show distinct geographic distributions. Further morphological studies on the Korean water deer will be required to confirm its taxonomic status.

Feeding habits of released Sebastes inermis obtained in daily and monthly collections from August 2007 to December 2007 in coastal waters off Jam Island in Jinhae Bay, Korea were assessed. A total 151 individuals of S. inermis (6.3-9.7 cm TL) were recaptured during the study period. Initial food intake of released S. inermis occurred within three days of released. Stomach content index increased with time, however, the percentage of stomachs devoid of contents decreased. Sebastes inermis mainly consumed gammarid and caprellid amphipods, gastropods and mysids. Diet also included small quantities of bivalves, shrimps, copepods and ostracods. Amphipods were mainly consumed at all size groups and consumption of gastropods, bivalves and shrimps increased with increasing fish size.

The authors studied the adrenotropic receptors of isolated urinary bladder from Sebastes inermis, using adrenergic activators such as epinephrine, nor-epinephrine, isoproterenol and phenylephrine and adrenergic blocking agents such as phenoxybenzamine, pronethalol and propranolol. The studies have revealed the following results. 1) The spontaneous motility of isolated bladder from Sebastes inermis was inhibited by epinephrine nor-epinephrine, isoproterenol and phenylephrine. 2) The inhibitory effect of phenylephrine on the Sebastes inermis bladder was blocked by phenoxybensamine. 3) The inhibitory effect of isoproterenol was blocked by pronethalol and propranolol. 4) The effect of epinephrine and nor-epinephrine on the Sebastes inermis bladder was usually not blocked by either kind of blocking agent alone, but was blocked by a combination of ${\alpha}\;and\;{\beta}$ blockades. 5) It is, therefore, concluded that the Sebastes inermis bladder has alpha and that both receptors, and that both receptors subserve retaxation or inhibition.

Seventeen fish species were counted in an underwater visual census, and the most common species, Sebastes inermis and Halichoeres poecilopterus, were released. More than 60% of the released S.inermis occurred near a fish farm 5 days after release, but they moved to a distant rocky area, and decreasing numbers were seen near the farm 90 days after release. In pots, a total of 722 individuals belonging to 43 species occurred, and released S.inermis dominated with 174 individuals recaptured during the study period. The other common fish species were Stephanolepis cirrhifer and Acanthopagrus schlegeli. The percentage of recapture was 0.23%, but declined to 0.12% at 90 days after release. The potential predators of released S.inermis included Lateolabrax japonicus and Sebastes schlegeli.

In the present study, the effect of Z. jujuba Miller var. inermis Rehder extracts on the secretion of atopic dermatitis (AD)-related cytokines and hyaluronidase activity was investigated. We prepared four fractions, butylene glycol (JB), ethanol (JE), and water (JW), with Z. jujuba Miller var. inermis extracts. JW significantly reduced the secretion of interleukin-8 and JE reduced the secretion of tumor necrosis factor-alpha in human keratinocyte HaCaT cells. Also, hyaluronidase activity was measured by enzyme assay and the fractions inhibited the activity in a dose-dependent manner. In addition, the human dermal fibroblast, HDF-n cells were treated with the extracts and antioxidant activities were measured. The results showed that the extracts increased the free radical scavenging activity and the superoxide dismutase activity. Taken together, Z. jujuba Miller var. inermis extracts reduced the secretion of AD-related cytokines and inhibited the hyaluronidase. In addition, the extracts showed antioxidant activity.

The objective of this study was to estimate the roadkill occurrence of water deer (Hydropotes inermis), a representative roadkill species in South Korea. For this estimation, I analyzed national road statistics and roadkill statistics, and then reviewed case studies that estimated the number of deer roadkill in other countries to apply the estimating methods to our case. As a result, the estimated number of water deer vehicle collision was at least 60,000 per year in South Korea.

Feeding habits of Sebastes inermis collected from the eelgrass bed in Kwangyang Bay from January 1994 to December 1994 were studied. S. inermis ($1\~9\;cm\;SL$) was a carnivore which mainly consumed amphipods (gammarid amphipods and caprellid amphipods) and copepods. Its diets included small quantities of caridean shrimps, crabs, gastropods, and fishes. It showed ontogenetic changes in feeding habits. In an initial stage, copepods were major food organisms. However, amphipods were heavily selected as the body size of S. inermis increases. Although consumption of copepods increased during spring, amphipods were major prey organisms for all seasons.

Characteristics of age and growth of the black rockfish, Sebastes inermis sampled in the Jeonnam Marine Ranching Area (JMRA) around Geumo Islands south of Yeosu were investigated using 642 otoliths from March 2009 to February 2010. The opaque zone was formed in September once a year and hence it was used as an annulus. The parturient period was December to January, and therefore the duration from fertilization to the complete formation of the opaque zone was nineteen months. From the parameters calculated using the average length when the year ring was formed, growth of S. inermis were expressed by von Bertalanffy growth equation as $L_t$=23.267 ($1-e^{-0.4406(t+1.1971)}$) for females and $L_t$=22.030 ($1-e^{-0.5312(t+0.6834)}$) for males when is total length in age t. Through the growth equations, the maximum length was determined as 23.27cm for females and 22.03cm for males and the growth factor as 0.4406/yr and 0.5312/yr, respectively. Finally, the growth of female S. inermis is larger than the one of male S. inermis.
