In order to understand the spatiotemporal variation of water quality, an investigation on variation characteristics of water quality was conducted at 13 stations in Yongil bay from 1990 to 1998. The salinity in summer was relatively lower than that in other seasons and it have increased from inner bay to outside of the bay gradually. However, nitrate concentration in summer was relatively higher than that in other seasons, and it was the highest, up to $65.40\%$, among dissolved inorganic nitrogens, Nitrate concentration indicates the possibility of affecting by freshwater discharges to Yongil bay. Correlation analysis showed that salinity had a significantly good correlation with nitrate. This result suggested that inflow of river had an influence on increase of nitrate. The result of Principal Component Analysis (PCA) indicated that nitrate was major factor to influence the water quality in Yongil Bay.

Along with the increasing social concern on cultural products and corresponding policy development by government many domestic regions have been trying to establish their own cultural identity. Based on the case stuffy for Gwang-Ju, this paper provides a methodology of developing cultural products from the unique regional resource. Its scope was classified into three categories: alread-developed, regional character and regional theme products. For this purpose, marketing strategies were established for quality improvement and promotion of cultural products through analysis on the current products including a questionnaire to customers. Then, conceptual designs for each scope were developed through the five steps of "selection of items", "target customer analysis", "concept establishment", "extraction of cultural factos7" and "derivation of conceptual design". The concept establishment was based on the expression of the material characteristics, the harmony of tradition and modernity, symbolization of images and so on. The cultural factors taken into account included the natural resources, historical heritages and landmarks. Finally, several examines of the conceptual designs were illustrated for commercial products. This study could be extended further in the future by introducing potential immaterial resources into the cultural factors.

This paper reports a case study of SevenBräu, the first company to acquire a license for small and medium scale beer manufacturing in Korea. This study explores how SevenBräu analyzed its consumers, competition, and environment to set its target market and successfully positioned itself to explore new markets in Korea. The company accomplished this through a mixture of marketing strategies with differentiated products and consumer benefits. SevenBräu has been growing fast and establishing its image as a "high-quality craft beer locally produced in a traditional way" and a "beer with regional characteristics," with young consumers (aged 20 to 35) as the main target. Such remarkable growth of SevenBräu can be attributed to factors such as: (1) product differentiation to satisfy the needs of consumers for taste, flavor, diversity, and freshness, (2) developing brands with regional characteristics and actively communicating its strategy through earned and owned media, and (3) sustainable management, considering both social value creation and environmental performance. Lastly, this case study presents challenges in the areas of brand management, value delivery network, and communication that SevenBräu needs to address in the beer market that faces increasing competition.

This study investigated the quality properties of glutinous rice Gochujang produced by regional rural families in order to determine the present state of quality of traditional Gochujang. A total of 80 Gochujang samples were collected from nationwide rural families and their physicochemical characteristics were analyzed. Based on regional mean, ranges of moisture contents, pH, acidity, crude protein contents, and salinity of Gochujang were $44.31{\pm}5.73%{\sim}50.50{\pm}5.65%$, $4.59{\pm}0.36{\sim}4.79{\pm}0.15$, $1.18{\pm}0.22%{\sim}1.54{\pm}0.36%$, $5.28{\pm}0.90%{\sim}6.93{\pm}.09%$, and $5.55{\pm}0.85%{\sim}8.29{\pm}1.19%$, respectively. The mean contents of amino type N, reducing sugars, and capsaicinoids were $488.81{\pm}79.74mg%{\sim}715.16{\pm}78.09mg%$, $22.32{\pm}9.43%{\sim}28.61{\pm}8.80%$, and $44.31{\pm}18.71mg/kg{\sim}65.15{\pm}47.98mg/kg$, respectively, and differences were significant among the Gochujang samples. Hunter color values (L, a, and b) of Gochujang were $4.84{\pm}3.08$, $21.26{\pm}10.53$, and $8.20{\pm}5.91$, respectively, and the range of viscosity was $31,511{\pm}11,764{\sim}72,923{\pm}32,555$ cP. The acidity, salinity, moisture, crude protein, and amino type N contents of Gochujang produced from the Gangwon-do and Gyeonggi-do areas were significantly higher than those of other regions. According to principal component analysis of the physicochemical characteristics of Gochujang produced by rural families, the salinity, acidity, moisture, crude protein, and amino type N contents were strong characteristics of Gochujang produced by Gangwon-do and Gyeonggi-do. These results indicate that traditional Gochujang produced by rural families shows various quality properties and regional differences in physicochemical characteristics.

This study was conducted to analyze the spatial and temporal characteristics of stream water quality and to charify the management of watershed environment from the standpoint of hydrological geography. To achieve the purpose of the study, the Wangsook River was chosen. As the result of this study, the specific conclusions were drawn. 1. In general, WT(water temperature) of the downstream is higher than that of the upstream. The value of winter WT measured in densely populated area is higher than that measured under the natural conditions. The seasonal variation of WT at upstream sites is greater than that of downstream. 2. Rhe water quality of main channel is dependent on that of tributaries. Especially, the values of pH, EC, TDS in main channel depend upon those of tributaries. Among the tributaries of the Wangsook river, the Jingun-chon and Yongam-chon have mostly influence on the water quality of the main channel. 3. Generally, the values of COD measured in the Wangsook River are over the 5th Grade considering from a point of water quality standards of inland lake. However, BOD, phosphorus and nitrogen concentrations have to be measured to clear the water quality conditions of the river. 4. The regional people who live in the catchment of Wangsook river have different perception about the water pollution of the river. The regional people lacks in the understanding of the Wangsook river cause a bad influence upon the hydrological management of watershed environment.

This study was conducted to estimation of change characteristics for water quality by the dyke gate operation in the Keum River estuary. The estimation data made use of surveyed data in Keum River estuary by NERDI (National Fisheries Research and Development Institute) during $1990\~1999$. Shown to compare water quality changes at st. A and st. D in Figure 1, the concentrations of TSS, COD and nutrients at st. A were as high as about $2\~4$ times than those at st. D due to affection of fresh water discharge in the Keum River. The percentages of water quality change at surface water by dyke gate operation in the Keum River estuary were shown that TSS (Total Suspended Solid) was decrease to $56\%,\;47\%$ at st. A and D, and COD (Chemical Oxygen Demand) was increase to $68\%,\;71\%$ at st. A and D, respectively. The changes percentage of DIN (Dissolved Inorganic Nitrogen) by dyke gate operation in the Keum River estuary were increase high to $95\%$ at surface water and $7\sim30\%$ at bottom water, but those of DIP (Dissolved Inorganic Phosphorus) were increase to $2.8\sim8.6\%$ at surface water and $28\%$ at bottom water. The range of fluctuation for water quality at each station by dyke gate operation has shown that salinity and TSS are little better than before dyke gate operation, but COD show highly fluctuation. Also we studied estimation of characteristics of water quality change by the season, COD was increased except the summer, TSS was decreased to all season. DIN was increased to about $61\sim172.1\%$ for all season, but DIP was increased to the spring and decreased to the autumn, DIN enrichment in the estuary by dyke gate operation are interpreted to improvement of organic matter decomposition and nitrification by increasing the residence time and to increase nutrient flux in sediments due to decreasing dissolved oxygen and increasing a deposit matter.
