  • In the present study, the community distribution, functional feeding groups, and habitat groups of the benthic macroinvertebrates from Gayasan National Park were investigated at eight different sites from 2015 to 2016. The correlation between habitat altitude and each group type was analyzed statistically. Biodiversity indices, including dominance, diversity, richness, and evenness indices, were calculated. The results showed a total of 4,216 individual benthic macroinvertebrates were collected, including 4 phyla, 6 classes, 16 orders, 40 families, and 100 species. Gammarus sobaegensis was dominant with 0.141% dominance, and the subdominant species was Epeorus nipponicus with 0.088% dominance. The EPT group(Ephemeroptera, Plecoptera and Tricoptera) accounted for 71.00% of the total species and 67.69% of the total individuals. The number of scraper species was highest, and the number of gathering collector individuals was highest among functional feeding groups. The individual number of scrapers(r=-0.358, p < 0.05) and gathering collectors(r=-0.343, p < 0.05) decreased with increasing altitude. The numbers of species and individuals of clingers and sprawlers were highest among the habitat groups. The individual number of clingers(r=-0.547, p < 0.01) and burrowers(r=-0.331, p < 0.05) significantly decreased with increasing altitude. The diversity and richness indices were higher in St. 3 than in the other sites. The dominance index was highest in St. 2, and the evenness index was highest in St. 7. We evaluated the biological water quality with several known methods, and concluded that ESB(Ecological score of benthic macrovertebrates community) and GPI(Group polution index) were more suitable than KSI(Korean saprobic index) and BMI (Benthic macrovertebrate index) to assess the biological water quality of Gayasan mountain stream water.

  • Based on the Merritt-Cummins system, the Korean immature aquatic and semiaquatic insects were reviewed and categorized into 6 different functional feeding groups (FFG) at the generic levels (257 genera belonging to 96 families, 10 orders),Among 257 genera, the most abundant FFG was the predator type consisting of 122(47%) genera. The second and third major groups were gathering-collectors (33genera, 13%) and shredders (21, 8%), respectively. Next group was occupied by scrapers (20,7%), and followed by filtering-collectors (12,5%) and plant-piercers (6, 2%). In addition, a total of 43 genera in 7 orders were remained as uncategorized groups. Both relative degrees of resistance and resilience of each genus were also analyzed to evaluate the role of each FFG in maintaining community stability. The results elucidated that the gathering-collectors and the scrapers could play a role as a pioneer group and a functional mediator in the community, respectively. The results also indicated that the practical use of relative resistance and resilience degrees could be applied to conduct comprehensive studies in stream ecosystems.

  • To evaluate the feeding effect of oriental medicine on the functional properties of pork, male pigs(Sus scrofa var. domesticus L.) were fed commercial basic diets containing 1.0%, 3.0% and 7.0% of oriental medicine complex from 30 or 45 days before slaughter. The growth pattern and physical conditions of pigs during the feeding period were checked, and after slaughter, the taste of pork and biological characteristics of serum were analyzed. Body weight gain was significantly increased in case of 45 day feeding groups of 3.0 and 7.0% compared with control group (p<0.05), whereas food intakes were slightly decreased in these groups. Triglyceride and total cholesterol levels were effectively decreased in the same feeding groups compared with control group (p<0.01~0.001). Three percent feeding group not only effectively decreased the LDL-cholesterol levels, but also sig-nificantly decreased the atherogenic index in 30 days(p<0.001). Malondialdehyde levels and hy-droxyl radical formations were effectively inhibited in all oriental medicine feeding groups. Superoxide dismutase activities were effectively increased only in 3.0% feeding groups, HDL-cholesterol levels almost did not change in 3.0% and 7.0% feeding groups in 30 days. External and sensory evaluations make satisfactory results in all oriectal medicines feeding groups. According to the experimental results, the growth pattern and physical nomditions of the pigs fed oriental medicine without feeding any antibiotics were relatively superior to those of control group. The authors suggest that, if more than 3.0% of oriental medicine were fed to the pigs from more then 30 days before slaughter the pork is reatively better than those of general pork not only for the modulating the chronic degenerative diseases, but also for its qualities and tastes.

  • Benthic macro invertebrate communities were collected at six different sampling sites in the Musucheon stream in Korea from July 2006 to July 2007, and ecological exergy values were calculated based on five different functional feeding groups (collector-gatherer, collector-filterer, predator, scrapper, and shredder) of benthic macro invertebrates. Each sampling site was categorized to three stream types (perennial, intermittent and drought) based on the water flow condition. Exergy values were low at all study sites right after a heavy rain and relatively higher in the perennial stream type than in the intermittent or the drought stream type. Self-Organizing Map (SOM), unsupervised artificial neural network, was implemented to pattern spatial and temporal dynamics of ecological exergy of the study sites. SOM classified samples into four clusters. The classification reflected the effects of floods and droughts on benthic macroinvertebrate communities, and was mainly related with the stream types of the sampling sites. Exergy values of each functional feeding group also responded differently according to the different stream types. Finally, the results showed that exergy is an effective ecological indicator, and patterning changes of exergy using SOM is an effective way to evaluate target ecosystems.

  • The main objective of this study is to find out the fauna of macroinvertebrate and composition of functional feeding groups about the aquatic insects to microhabitat from the Geum River, Korea. This study is based on investigations of the main channel of Geum River, Korea which is upstream of Daecheong Dam, and carried out in the spring and autumn of 2004. Collections from all the sites were 39,532 individuals, 130 species, 54 families, 16 orders, 7 classes, and 4 phyla of macroinvertebrates. Aquatic insects were composed of 90.76% (118 species) and 98.88% (39,088 individuals) of all the identified species. Among the microhabitats, the riffles were collected 26,293 individuals and 92 species, and the runs were collected 12,329 individuals and 89 species. Finally, the pools were collected 494 individuals and 41 species. In this survey, the proportions of functional feeding groups of aquatic insects were as follows (percent of identified): predators 37.65%, gathering-collectors 23.53%, scrapers 16.47%, filtering-collectors 11.76%, shredders 9.41% and plant-piercers 1.18%. Also, the functional feeding groups were sorted according to microhabitat, in the riffles 30.65% were predators and 29.03% were gathering-collectors; in the run 30.3% were predators, and 28.79% were gathering-collectors; while in the pools 36.67% were predators, and 30.0% were gathering-collectors. In all microhabitats, gathering collectors and predators were predominant, because most of the survey sites are in the midstream. Also, the scrapers were shown more frequently in the riffle (17.74%) and run (18.18 %) than pool (13.13%), the filtering-collectors were shown more frequently in the riffle (14.52%) and the run (12.12%) than the pool (6.67%), and the plant-piercers (3.33%) were found only in pools. But the shredders weren't a difference in the run (10.61%), the pool (10.0%) and the riffle (8.06%), because of the characteristic. Microhabitats (riffle and run) are much alike in composition ratio of functional feeding groups and pool was very lower out of composition ratio in microhabitats. But riffle is very important than run, because most of individual occur in streams. Besides, pool was diverse to composition ratios, considering the number of individuals.

  • The Shinbulsan wetland, located in Yangsan-si, Gyeongsangnam-do, South Korea, was designated as a conservation area in 2004. The area was monitored from 2015 to 2019 to investigate the community characteristics and changes of benthic macroinvertebrates. Between 2015 and 2016, several insects of the orders Ephemeroptera, Odonata, and Hemiptera were identified, but their numbers decreased significantly in 2017 and 2018 following the loss and recovery of the moor owing to drought. During this period, there were relatively more insects of the order Diptera. Within this order, three functional feeding groups, gathering-collectors, plant-piercers, and predators were investigated. Predator species were the most abundant (83.3%), whereas gathering-collectors accounted for the largest proportion of individual insects (50.5%). Between 2015 and 2016, when the moors were stable, groups I and III had the highest community stability. After 2017, when the moors had dried up, group III effectively disappeared because of its lower relative resistance and resilience, and only taxa belonging to group I remained. The results of this study indicate that benthic macroinvertebrates that adapt early during moor formation inhabit the Shinbulsan wetland.

  • The species composition and abundance of aquatic insects were investigated by light trap in summer, 2002 at three stations in the Chikuma River, Japan's longest river. A total of 3278 adults/day were collected, the great majority (57.5%) of which were Diptera, followed by Trichoptera (35.4%) and then Ephemeroptera (7.1%). The number of collected aquatic insects and their biomass gradually increased towards downstream, whereas the number of species and species diversity index (H') decreased. 36 species (H'= 4.30) of aquatic insects were collected at St. 1, versus 31 species (H'= 2.81) at St. 3. Moreover, the relative abundance of functional feeding groups changed from St. 1 to St. 3, i.e., 'collectors' increased and 'shredders' decreased.

  • Background and Purpose : The hemiplegic upper extremity is affected in many stroke patients, and recovery is often poor. The purpose of this study was to assess the efficacy of electroacupuncture (EA) in enhancing the upper extremity motor and functional recovery of ischemic stroke patients. Subjects and Methods : Forty ischemic stroke patients (the upper extremity Fugl-Meyer motor scale (FM) score lower than 46, lesion location within middle cerebral artery territory) within 2 weeks of stroke onset were randomly allocated to either an EA group that received EA treatment or a control group that received only routine ward care. The EA was applied at Quchi-Shousanli (LI11-LI10), Waiguan-Hegu (TE5-LI4) points on the hemiparetic side six times per week for 4 weeks. The frequency of stimulation was 25-50Hz and the intensity was set at a level sufficient to induce muscle contraction. EA treatment was given for 30 minutes and all patients of both groups received standard rehabilitation program. Outcomes were assessed, in a blind manner, before treatment began and at 4 weeks after treatment, with the FM, the Motor Power score (MP) for shoulder/elbow, and the subsection of the Modified Barthel Index (MBI) for drinking/feeding/dressing upper body/grooming. Results : These 2 groups had comparable clinical characteristics, lesion location, lesion size, and pretreatment impairment scores. By the end of treatment, the EA group showed significantly more improvement than the control group in the subsection of the FM for shoulder/elbow/coordination (6.4 vs. 3.7; P=0.047) and the MP for shoulder/elbow (5.3 vs. 3.3; P=0.008). The subsection scores of the MBI for drinking/feeding/dressing upper body/grooming were not significantly different between two groups. No adverse effects due to treatment were found Conclusion : These results suggest that EA enhances the upper extremity motor recovery of acute stroke patients. However, this study failed to demonstrate any significant functional benefit related with upper extremity. Future study should be carried out in a larger sample size and use the functional outcome measure that is more specific and sensitive to the upper extremity.
