Taste receptors of the anterior tongue are innervated by the chorda tympani (CT) branch of the facial (VIIth) nerve. The CT nerve transmits information on taste to the ipsilateral nucleus of the solitary tract (NST), which is the first taste central nucleus in the medulla. Taste information is known to be transferred ipsilaterally along the taste pathway in the central nervous system. Some patients with unilateral CT damage often retain their ability to sense taste. This phenomenon is not explained by the unilateral taste pathway. We examined whether neurons in the NST receive information on taste from the contralateral side of the tongue by measuring c-Fos-like Immunoreactivity (cFLI) following taste stimulation of the contralateral side of the tongue in the anesthetized rats. We used four basic taste stimuli, 1.0 M sucrose, 0.3 M NaCl, 0.01 M citric acid, 0.03 M QHCl, and distilled water. Stimulation of one side of the tongue with taste stimuli induced cFLI in the NST bilaterally. The mean number of cFLI ranged from 23.28 ± 2.46 by contralateral QHCl to 30.28 ± 2.26 by ipsilateral NaCl stimulation. The difference between the number of cFLI in the ipsilaterl and contralateral NST was not significant. The result of the current study suggests that neurons in the NST receive information on taste not only from the ipsilateral but also the contralateral side of the tongue.
Extension of bus service areas using genetic algorithm
Yiseul Kang,박수홍 대한공간정보학회 2016 Spatial Information Research Vol.24 No.6
Since the traffic congestion due to continuous inflow of population to the cities has been raised, the public transportation system has been developed for solving such issue. But the usage rate of passenger car which is personal transportation is still high, indicating an inadequate transition in the means of transportation. Although there may be variousreasonsforthis,theimportanceofaccessibilitytothe means of public transportation has been pointed out frequently. The purpose of this study was to secure a balanced bus service by solving inequality in the usage of public transportation occurred according to the spatial location, with focus on the bus service. The bus service shadow areas were extracted by carrying out a bus service shadow areas extraction technique applied with the spatial analysis using public data provided based on Government 3.0. The bus serviceshadowareasextractiontechniquehasatotalofthree stages, extracting the bus service area, extracting the road at which bus can stop and extracting the area where bus service is needed. In order to design a proper route for the extracted shadow area, a bus route design technique applied with the genetic algorithm was presented. Since the travel demand of potential passengers and the existing routes are considered forthistechnique,itispossibletomeetthetraveldemandand design a bus route with minimal overlapping with the existing routes. It is expected that the result of this study could increasetherateofbususage by improvingtheservice level of bus. It is also expected that the result could help relieving traffic congestion by minimizing overlapping with the existing routes and reduce time and economic loss through flexible route design that reflects constantly changing traffic environments and travel characteristics.
Comparative study of chemical tolerance between Drosophila melanogaster and Drosophila suzukii
YiSeul Kim,Sungho Lee,YeongHo Kim,Young Ho Kim 한국응용곤충학회 2018 한국응용곤충학회 학술대회논문집 Vol.2018 No.04
Drosophila melanogaster and Drosophila suzukii are the species of the family Drosophilidae. Although these two fruit flies are taxonomically close species, D. suzukii is thought to be evolutionally adapted to the flesh or maturing fruits, whereas D. melanogaster is adapted to more fermented environments. According to the previous studies, several environmental toxins, such as acetic acid, ethanol, methanol and phenylacetate, ect., have been identified from rotten fruit and fermentation procedures. Considering the differences of distinct habitat between two flies, D. melanogaster is hypothesized to exhibit higher tolerance to the chemical toxins than D. suzukii. Therefore, in this study, we compared the tolerance and susceptibility of two fruit flies to three chemicals (acetic acid, ethanol, 2-phenlyethano).

This study investigated to find optimal blanching conditions for pre-treatment of Korean Cahmchi (Aster scaber) before freezing to maintain qualities as food ingredient. Blanched A. scaber were blanched in water, 1% sucrose solution and 1% salt solution for 2min. After blanching, each sample packed with water, 0.5% and 1% sucrose solution, which were half quantity of sample. The samples were then frozen at -30°C freezer for 24h. Frozen samples were thawed in water at 4°C. Color, thawing loss, water content and texture analysis were evaluated. Water content was not significantly different among samples. Thawing loss of A. scaber was low value in sugar and salt additive samples. Sugar additive sample indicated the lowest redness and yellowness value. Also sugar added samples showed tender texture. In conclusion, sugar contents in blanching water were affected to qualities of A. scaber.
