In this study, the concept of 'Musim' presented by Baegun Hwasang was analyzed from the viewpoint of a bibliography. Major findings are as follows: First, it is reasonable to translate 'Musim' into Korean to mean (1) 'free from cares', (2) 'there is noting called a heart', and (3) 'no anxieties' according to the context of praises. Second, Musim by Baegun means 'calm mind without any trembles in ordinary times', 'unload any worries', and 'the spirit of awakening'. Such concepts of Musim agree with the praises of 'Awakening by seeing through a person's own heart' presented by Dalma Josa, and 'Unloading any worries' presented by Buddha. Therefore it is understood that Musim is the mental state of 'being free from cares which seek and hold', and Baegun Hwasang presents his experiential awakening 'by keeping his mind calm without any trembles in ordinary times, unloading any worries, and freeing himself from cares'. Third, it is confirmed that Musim by Baegun when compared with the praises presented by 'Gwageo 7 Buls' and 'Seocheon 6 Josas' in Jikji, firmly holds the ideas of Buddha's 'Unloading any worries' and Seocheon Josa's 'Neutral perspective based on double negations'. Therefore, Baegun Hwasang's 'Musimseon' which especially emphasizes 'Musim' is the method of meditation which most clearly inherited the nature of Dalma Seonjong or Yukjo Hyeneung, and Imjejong's meditation.

The purpose of this study is to realize the teaching material, which develops the Model of Watershed Water Environment Education(EE) Textbook, by seeking for a method of the Inquiry with the Perspective of EE and by questing for the contents of watershed water environment necessary for Water EE with the Perspective of EE. First, the value of watershed EE was reilluminated through the literature analysis on the watershed. And 'Inquiry with the Perspective of EE' methodology was newly presented that quests for the contents necessary and proper for EE from the viewpoint of EE. Also, with suggesting it as concept and methodology of 'Inquiry with the Perspective of Watershed EE' by considering the value of EE in Water EE, it presented the content approach direction in the inquiry and the contents of the specific inquiry. Second, through the Inquiry with the Perspective of EE into water environment of the watershed Musim cheon (stream), which is a case region, it allowed the watershed water environment to be able to be synthetically understood. As for a sphere of the inquiry, 5 spheres were sought by taking into account a relation to a human being, as well as the water environment itself of the watershed Musim cheon (stream). Third, Based on the contents of the Inquiry with the Perspective of EE into the watershed Mlisim cheon (stream), 'the Model of Watershed Water EE Textbook' for middle-school students was developed. This model of textbook was selected largely four parts, and was organized with 10 learning objectives and 11 activities.

This study compared and analyzed EPT ratio, EPT richness and EPT number(number of species and individuals) of a total of 9 selected sites individually using EPT-group of aquatic insects in Musim stream, also compared similarity ratio between the sampling sites using UPGMA(Unweighted Paired Group Method using Arithmetic average) based on analysis subsequent to species structure of aquatic insects, and compared and analyzed a functional feeding groups(FFGs) of aquatic insects based on stream order. As a result, the aquatic insect group of 2,269 individuals is classified as 71 species, 36 families, and 8 orders, and EPT ratio and EPT richness at sites 3(0.72 and 3.89, respectively) were found to be relatively higher than those at the other sites; by contrast, those at site 9(0.03 and 0.09, respectively) were relatively low. EPT number of species and individuals was found to be lowest at site 9. As a result of UPGMA analysis, the sampling sites in Musim stream were divided into three groups, including A1(site 1, 7, 8), A2(site 2, 3, 4, 5, 6) and B(site 9). According to the results of FFGs, there was not shown specific difference in the number of functional feeding groups by each sites; however, there appeared a little more shredders and scrappers in the upper and mid stream comparing to other sampling sites while collector-filterers and collector-gatherers were found to be dominant in number in the lower stream. According to this research result, the sampling sites in Musim stream were found to have an effect on not only EPT richness, EPT ratio, and EPT number but also FFGs structure.

The 30-year design flood hydrograph for the Musim Representative Basin, one of the study basins of the International Hydrological Program, is synthesized by the method of unit hydrograph. The theory of unit hydrograph has been well known for a long time. However, the synthesis of flood hydrograph by this method for a basin with insufficient hydrologic data is not an easy task and hence, assumptions and engineering judgement must be exercized. In this paper, the problems often encountered in applying the unit hydrograph method are exposed and solved in detail based on the theory and rational judgement. The probability rainfall for Cheonju Station is transposed to the Musim Basin since it has not been analyzed due to short period of rainfall record. The duration of design rainfall was estimated based on the time of concentration for the watershed. The effective rainfall was determined from the design rainfall using the SCS method which is commonly used for a small basin. The spatial distribution of significant storms was expressed as a dimensionless rainfall mass curve and hence, it was possible to determine the hyetograph of effective design storm. To synthesize the direct runoff hydrograph the 15-min. unit hydrograph was derived by the S-Curve method from the 1-hr unit hydrograph which was obtained from the observed rainfall and runoff data, and then it was applied to the design hyetograph. The exsisting maximum groundwater depletion curve was derived by the base flow seperation. Hence, the design flood hydrograph was obtained by superimposing the groundwater depletion curve to the computed direct runoff hydrograph resulting from the design storm.

The phytosociological investigation was carried out at 32 sites of the riparian vegetation in Musim-Chon stream passed through Choengju-City, Chungcheongbuk-Province by Braun-Blanquet's method from August to October, 1997. The flora of vascular plants in this survey was 202 species. The riparian vegetation was classified into 25 communities as follows. The submerged hydrophytes are Potomogeton malaianus var. latifolius community, Potomogeton crispus community, Myriophyllum verticillatum community-Hydrilla verticillata community and Ceratophyllum demersum community. The floating-leaved hydrophyte is Trapa japonica community. The emerged hydrophytes are Phragmites communis community, Perzicaria thunbergii community, Phragmites japonica community, Oenanthe javanica community, Zizania latifolia community and Persicaria hydropiper community. The herbaceous vegetation of floodplain are Artemisia montana community, Humulus japonicus community, Miscanthus sacchariflorus community, Erigeron anmus community, Impatiens balsamina community, Bidens frondosa community, Setaria viridis community, Ambrosia artemisiifolia var. elatior community and Eragrostis ferruginea community. The woody vegetation of floodplain are Robinia pseudo-acacia community, Stephanandra incisa community and Clematis apiifolia community. The species diversity was low in the upper and down stream, while the diversity was high in the mid stream situated at the center of Choengju-City because of frequent disturbance by citizens. These results suggested that distribution of communities and species diversity was closely related to the disturbance.

Total Maximum Daily Load(TMDL) is a core basin management system to assign total emissions of pollutants to unit basin and emission source within a limit of the target water quality and to secure sustainability. considering "Environment and development" together. By current technical guidance of TMDL, the water quality in the riverbed of which the target water quality is noticed, must achieve the target; and the water quality standard for evaluating achievement of the target should be prescribed as non-excessive probability quality of water on the basis of the pertinent water quality documents. Therefore, the study calculated the target water quality by each unit basin which the target water quality must be noticed through the analysis of probability for water quality documents in rivers at the time of establishing a plan, and the study evaluated the achievement possibility of the target water quality by analyzing and comparing the target water quality plan with the standard water quality to evaluate the achievement of the target water quality. As the result, applying the proposed method to Mihocheon River system, it is concluded that selected the target water quality (Each BOD 3.3mg/1 and BOD 3.0mg/1) in Miho A and Musim A is available. Of course, it showed that the target water quality: BOD 2.5mg/1 in Miho A and BOD 3.0mg/1 in Musim A, could be achieved if the small reduction in B unit area was implemented.

Present study was performed to survey infection status of digenetic trematode metacercariae in 2 alien fish species, Micropterus salmoides (largemouth bass) and Lepomis macrochirus (bluegill), in 2 rivers draining Chungcheongbuk-do, Republic of Korea. A total of 107 largemouth bass and 244 bluegills were caught in Daecheong-ho (ho=lake) and Musim-cheon (a branch of Geum-gang), in Chungcheongbuk-do April-July 2015. Additionally, 68 native fish of 5 species, i.e., Zacco platypus, Hemibarbus longirostris, Carassius auratus, Pseudogobio esocinus and Puntungia herzi, were caught from the same water bodies. All of the fish collected were examined by artificial digestion method. The metacercariae of Centrocestus armatus, Clinostomum complanatum, Metagonimus sp. and Diplostomum spp. were detected from 4 out of 5 native fish species in Daecheong-ho. However, any metacercariae were not found from 87 M. salmoides and 177 L. macrochirus in Daecheong-ho. In Musim-cheon, metacercariae of Exorchis oviformis and Metacercaria hasegawai were detected from 78% Z. platypus and 34% L. macrochirus, but any metacercariae not found in M. salmoides. We report here that the 2 alien fish species were less infected with the metacercariae than the native ones. Surveys on the metacercariae in the alien fish species in geographically various rivers should be undertaken for better understanding on the role of alien fish species in the trematode infections in Republic of Korea.

This study conducted water quality projection of year 2010 in Miho stream of the Geum river basin by using GIS. Pollutant load data of corresponding tributary of the Miho stream is estimated based on the pollutant load of TMDL zone to simulate water quality of the Miho stream for BOD, TN, and TP. The pollutant load of the urban area such as Bochung and Musim stream basin is relatively high and the wastewater treatment plant of Chunju city directly affects the entire water quality of the target area. As a result, simulation result reveals that water treatment facility needs more refined treatment process for efficient water quality management. Also, to meet the target water quality of the Miho stream water quality simulation estimates the additional dilution flow by increasing irrigation water supplied from the Daechung dam through the Musim stream.
