This research were aimed to verify possible transferring regional development's value into festival contents. It was widely known that Korean festival's theme has been relatively pale in comparing its abundancy, which were required variety of festival contents. Luckily, local residents in Cittaslow frequently host slow-themed festivals, not only to revitalize their communities but also to serve the visitors. Those phenomenon shed the light to study the culture tourism interpreters' role as the presenter of regional development value to visitors at festival setting. Total 180 of questionnaires were administered to Gimsatgat festival visitors, verifying the relationship of variables, interpreters' role, perception of festival theme, revisit intention and practice intention. Regression analysis revealed that significantly influential relations between variables. Successful interpreters will support visitors' understanding of Cittaslow value, satisfaction and practice in daily life. Theoretical /practical significances and research limitation were included.

The present study was performed to examine on the fauna and standing crops of benthic macroinvertebrates in Pongwha and Youngwol region of upper parts of south han river and Naktons river. The Actual site suvry was caried out on the two times during the April·June to October·November, 1988. Main five areas are Mt. Awrawe(1,067m), Mt. Sontal (1,236m), Mt. Munsu(1,206m), Peak Okyopong(357m) and Mt. Pungnak(760m) area. Total taxa of benthic macroinvertebrates of the study area were 118 species, 45families12 orders, 5 classes in 4 phyla. Occurrence species according to the major taxa of aquatic insects were 35 species (29.66%) in ephemeroptera, 25 species(21.19%) in trichoptera, 25 species(21.19%) hemiptera, 1 species(0.85%) in megaloptera. Non-aqautic insect were 5 species in mollusca, 3 ratio was 8.5 percent. Occurrence species(plecoptera) at clean waters were appeared 12 species at Mt. Awrawe and Sontal area. Occurrence species at each survey area was 67 species at Mt. Awrawe area, 60 species at Mt. Sontal area, 43 species at Mt. Munsu area, 37 species at Mt. P'ungnak area and 34 species at Peak Okyo area, respectively. Species diversity indices were 2.96~3.80 at Mt. Awrawe area, 2.79~3.62 at Mt. sontal area, but 2.64~3.12, 1.59~2.46 and 1.98~2.59 at, Mt. Munsu, P'ungnak and Peak Okyo area, respectively. In this region, occurrence species and individual density were smaller than that of Dong river with good habitat, but those were more abundant than that of Poseong river with similar environment conditions. Therefore, occurrence species and individual density of the present survey region were appeared as somewhat abundant.

During the period of 1975∼77, a survey and an investigation were carried out to estimate the frequency of lime-chlorosis in the natural vegetation in Korea and the relationships between plants and calcareous soils. The symptoms of lime-chlorosis were observed in flowering plants in the calcareous areas of Weonju (I, II), Yeongweol(I, II), Jecheon, Danyang and Samcheok. Although the species found to be lime-chlorotic on at least one occasion numbered 60, the total quantity of lime-chlorotic foliage observed was small. Severe lime-chlorosis of Capsicuym annuum in agricultural fields was found out at Danyang. However, some of the species which were of widespread occurrence in affected areas showed no lime-chlorosis. The comparison of the inorganic components in calcareous soils in lime-chlorotic and normal leaves showed that the essential mineral nutrients substantially less soluble in water in alkaline than in acid conditions and calcifuges planted on calcareous soils often show visual signs resembling those of P or Fe deficiency.

The low fow analysis for small-mid sized river basins is very difficult because of insufficient flow data or ungauged basins. The objective of this study is to suggest effective method of low flow using area function method for calculating Total Maximum Daily Loads (TMDL) by considering environmental carrying capacity. Two watersheds which are Juchon watershed having $606km^2$ areas and ungauged watershed having $4,551km^2$ areas were selected for this study. As a result of application, the low flow in the downstream of Juchon River and the Han River after confluence of Okdong River were $1.9m^3/s$ and $20.7m^3/s$, respectively. Then we consider the target BOD of 1.0-1.2mg/l in Youngwol prefecture, the TDML was estimated 164-197kg/day and 1,788-2,146kg/day, respectively. This approach will useful for estimating TDML to insufficient watershed of flow data and ungauged watershed of flow data.

RAPD analysis using random primers were tried to evaluate the genetic variation and diversity of the nine garlic cultivars including two foreign varieties. Thirty-two primers out of 70 primers screened were used to amplify genomic DNA of garlic cultivars using polymerase chain reaction(PCR). Among a total of 151 bands amplified by 32 primers, 125 polymorphic bands were subjected to analysis for genetic relationship of garlic cultivars. The estimated size of amplified PCR products were in the range of 932 to 4,060 base pairs. Nine garlic cultivars were classified into two groups, such as group I corresponded to Changnyung and Hungary cultivars, and group II, Namdo, Sandong from China, Yecheon, Euiseong, Youngweol, Danyang, Jeongsun cultivars, with the genetic distance value of 0.271. The major ecological types of garlics, so called southern and northern types, was grouped in the genetic distance value of 0.200. The results presented in this study suggest that RAPD analysis are likely to be useful for identification of cultivars and evaluation of genetic origin in garlics.

In this study, the characteristics of $PM_{2.5}$ and $PM_{2.5-10}$ concentrations were identified in two different functional areas including Chuncheon and Youngwol, Korea. Even though the anthropogenic emission rates of $PM_{2.5}$ and $PM_{10}$ are approximately four times higher in Youngwol than in Chuncheon their atmospheric concentrations were statistically higher in Chuncheon. In Chuncheon, both $PM_{2.5}$ concentrations and the ratio of $PM_{2.5}/PM_{10}$ increased as relative humidity (RH) increased possibly because the inorganic and/or organic secondary aerosols were actively formed at high RH. This result was also supported by that $PM_{2.5}$ concentration was enhanced under the fog and mist conditions in Chuncheon. On the other hand, both $PM_{2.5}$ and $PM_{2.5-10}$ concentrations clearly increased with the southerly winds blown from the cement production facility in Youngwol. In addition, high $PM_{2.5-10}$ concentrations were observed with high wind speed, low relative humidity, and high $NO_2$ concentrations in Youngwol, suggesting that $PM_{2.5-10}$ was generated through the physical process including crushing and packing procedures followed by resuspension from cement and lime factory.

In this study, the possibility of the utilization of coal ash as earthwork materials is investigated. For this purpose, some laboratory experiments were carried out. The samples used in these tests are fly ash(FA), bottom ash(BA), coal ash dropped into ash pond(FA:BA=8:2), and mixed coal ash(FA:BA=5:5), which were discharged as a by-product at Yong-Yeul thermoelectric power plant, and general road filling materials. And for the deformation analysis of coal ash reclamation ground, several hyperbolic model parameters were determined by triaxial compression test. As a result of this study, coal ash has excellent engineering properties such as strength parameters comparing with general soils of the same grain size, especially in case of being used as backfill materials and reclamation materials on soft ground, and coal ash is superior to general earthwork materials in engineering properties becasuse of self hardening behaveiour, light weight property, etc.

Both exponents of distance and elevation into distance-and-elevation ratio method for estimating missing rainfall data are expressed as squares together but in this study the two exponents are differently separated and analyzed. We used 326 hourly rainfall events of precipitation data during 10 years of 2004 to 2013 observed at a base station of Pyeongchang and the five neighboring index stations-Bangrim, Suju, Cheongoksan, Jinbu, Yeongwol1-in Han River basin for a case study. As a result, exponent values of distance and elevation appropriate for a topography of the site appear as 3.7 and 0.57 respectively. The exponents of distance and elevation difference need to be applied according to topographical characteristics of site where estimating missing data or interpolation are required.
