  • Characteristics of sex ratio and morphometric traits of induced allotriploid between female rainbow trout, Oncorhynchus mykiss and male cherry salmon, O. masou were performed. Sex ratios in both rainbow trout and cherry salmon were equally 1:1, while hybrid and allotriploid revealed higher proportion of male offspring (p<0.01). Body trait measurements of allotriploid in head hight/head length, length of dorsal fin base/body length and length of pectoral fin/body length were intermediate to their parental species, while in length of upper jaw/head length, allotriploid much more resembled that of rainbow trout. These facts proved that allotriploidization improved characters in sex ratio and morphometric traits compared to those o their parental species.

  • This study is designed to provide forest managers and landowners with tools to estimate the effect of forest management on carbon storage, investigating living tree biomass, detritus, and harvested wood products as variables. Thinning, selection cutting, and uncutting were applied to the three different forest types in New York, USA. Carbon storage of the original stands was 90, 56, and $101Mg\;ha^{-1}$ at the Allegheny hardwood forest, Northern hardwood forest, and Oak - black cherry forest, respectively. Among treatments, uncutting generally stored the greatest amount carbon. However, the rate of carbon storage was the smallest at the uncut treatment in all the sites. The 50% thinning, 50% selection, and 50% thinning treatments were the highest rate of carbon storage at the Allegheny hardwood forest, Northern hardwood forest, and Oak - cherry forest, respectively. In this study, only short term was applied to simulate carbon sequestration after silvicultural treatment. So, more research is needed to determine whether any silvicultural treatment can store significantly more carbon than no treatment over the long term.

  • Selenium (Se)-rich binary Cu-Se and In-Se nanoparticles (NPs) were synthesized by a modified heat-up method at low temperature ($110^{\circ}C$) using the gum exudates from a cherry blossom tree. Coating of CISe absorber layer was carried out using Se-rich binary Cu-Se and In-Se NPs ink without the use of any external binder. Our results indicated that the gum used in the synthesis played beneficial roles such as reducing and capping agent. In addition, the gum also served as a natural binder in the coating of CISe absorber layer. The CISe absorber layer was integrated into the solar cell, which showed a power conversion efficiency (PCE) of 0.37%. The possible reasons for low PCE of the present solar cells and the steps needed for further improvement of PCE were discussed. Although the obtained PCE is low, the present strategy opens a new path for the fabrication of eco-friendly CISe NPs solar cell by a relatively chief non-vacuum method.

  • In an effort to evaluate the qualities of the unused woods designed for art materials, Yellow pine, Pitch pine, Suwon poplar, Platanus and Cherry grown in Korea has been investigated in the study. Physical and mechanical properties such as density, hardness, roughness, and abrasion of the woods were examined. Among the five species, Cherry wood showed the highest density in green, air-dried and oven-dried conditions. Hardness of Cherry wood was higher than those of Suwon poplar and Platanus. In softwoods, Pitch pine showed greater hardness than Yellow pine. Yellow pine and Platanus had the highest values of wood surface roughness. Abrasion value of cross, radial and tangential sections was the highest in Yellow pine and Suwon poplar. It has been concluded from the experiment that physical and mechanical properties such as density, hardness, roughness, and abrasion of the woods can be used as an indicator of the suitability for woodcraft material.

  • Objective : The parafascicular nucleus (PF) plays important roles in controlling the basal ganglia. It is not well known whether the PF affects the development of abnormal involuntary movements (AIMs). This study was aimed to find a role of the PF in development of AIMs using optogenetic methods in an animal model. Methods : Fourteen rats were underwent stereotactic operation, in which they were injected with an adeno-associated virus with channelrhodopsin (AAV2-hSyn-ChR2-mCherry) to the lateral one third of the PF. Behavior test was performed with and without optical stimulation 14 days after the injection of the virus. AIM of rat was examined using AIM score. After the behavior test, rat's brain was carefully extracted and the section was examined using a fluorescence microscope to confirm transfection of the PF. Results : Of the 14 rats, seven rats displayed evident involuntary abnormal movements. AIM scores were increased significantly after the stimulation compared to those at baseline. In rats with AIMs, mCherry expression was prominent in the PF, while the rats without AIM lacked with the mCherry expression. Conclusion : AIMs could be reversibly induced by stimulating the PF through an optogenetic method.

  • Large amounts of leaves from street trees fall onto the streets annually and need to be cleaned and treated. Cherry trees are common street trees in Korea. The adsorption characteristics of Pb(II) by cherry leaf (CL) and cherry leaf-derived biochar (CB) were studied through a series of batch experiments. CB was produced through the carbonization of CL at $800^{\circ}C$ for 90 min. Carbonization increased the C content and pH value, while decreased H and O contents. Well developed pore structure was observed at the surface of CB. The pseudo-second order model better described the kinetics of Pb(II) adsorption onto CL and CB, indicating that the rate-limiting step of the heavy metal sorption is chemical sorption. Fast adsorption rates and high adsorption capacities were obtained by the carbonization from CL to CB. Langmuir models better adequately described the Pb(II) adsorption onto CL and CB. Maximum adsorption capacities of Pb(II) expressed by Langmuir constant, $Q^0$ were 37.31 mg/g and 94.34 mg/g, when CL and CB were used as adsorbents, respectively.

  • Cherry silverberry (Elaeagnus multiflora) contains bioactive phenolics. This study was conducted to determine whether feeding cherry silverberry wine (CSW) to rats would alleviate the progress of alcoholic fatty liver. Adult male Sprague-Dawley rats were divided by weight into the following three groups. Two groups of rats were fed 6.7% ethanol or the caloric equivalent Lieber-DeCarli diet containing maltose-dextrin, and the other group an isocaloric Lieber-DeCarli diet containing CSW at the same ethanol level for 6 weeks. CSW's flavonoids, its antioxidant and free radical scavenging activities, serum transaminases, serum and hepatic lipids, and liver histology were examined. Our results showed that CSW exerted significant antioxidant and radical scavenging activities. The serum activities of alanine and aspartate transminases were markedly decreased by CSW at 6 weeks. Also, CSW feeding resulted in significant reductions in blood cholesterol and triglyceride. The development of alcoholic fatty liver was significantly delayed by lowering fat accumulation. Taken together, these results indicate that CSW may help protect the liver against alcoholic fatty liver by improving serum and hepatic lipid status. This may be associated with the protective effect of CSW on alcoholic fatty liver via bioactive phenolic compounds.

  • A shift of first fowering date (FFD) of spring blossoms (cherry, peach and pear) over the northest Asia under global warming is investiaged using dynamically downscaled daily temperature data with 12.5 km resolution. For the study, we obatained gridded daily data with Historical (1981~2010), and Representative Concentration Pathway (RCP) (2021~2100) 4.5 and 8.5 scenarios which were produced by WRFv3.4 in conjunction with HadGEM2-AO. A change on FFDs in 21st century is estimated by applying daily outputs of WRFv3.4 to DTS phonological model. Prior to projection on future climate, the performances of both WRFv3.4 and DTS models are evaluated using spatial distribution of climatology and SCR diagram (Normalized standard deviation-Pattern correlation coefficient-Root mean square difference). According to the result, WRFv3.4 and DTS models well simulated a feature of the terrain following characteristics and a general pattern of observation with a marigin of $1.4^{\circ}C$ and 5~6 days. The analysis reveals a projected advance in FFDs of cherry, peach and pear over the northeast Asia by 2100 of 15.4 days (9.4 days). 16.9 days (10.4 days) and 15.2 days (9.5 days), respectively, compared to the Historical simulation due to a increasing early spring (Februrary to April) temperature of about $4.9^{\circ}C$ ($2.9^{\circ}C$) under the RCP 8.5 (RCP 4.5) scenarios. This indicates that the current flowering of the cherry, peach and pear over analysis area in middle or end of April is expected to start blooming in early or middle of April, at the end of this century. The present study shows the dynamically downscaled daily data with high-resolution is helpeful in offering various useful information to end-users as well as in understanding regional climate change.

  • Light emitting diodes (LED) are able to selectively control the wavelength of light, enabling them to enhance photosynthesis by increasing specific wavelengths. The objectives of this study were to determine the effects of LED light exposure with various wavelengths (630 nm: 550 nm: 450 nm=8:1:1) on plant growth and bio-active compound concentrations in cherry tomato and red cabbage. With cherry tomatoes, LED decreased the number of fruits compared to fluorescent light (FL) but resulted in a significantly higher value in the total weight of the fruits and in sugar content. However, lycopene contents were not significantly different between the groups. With red cabbages, the weight and length were both significantly higher in the LED group than in the FL group. Furthermore, the anthocyanin contents in the red cabbage LED group were two times higher than those of the FL group. These results suggested that exposure to LED light with a high ratio of red wavelength can increase the anthocyanins contents in red cabbages but not the lycopene content in cherry tomatoes. Further studies will be needed to determine which LED wavelength can enhance lycopene content in cherry tomatoes.
