The purpose of current study is to develop and estimate a proposed model that explains the potential relationships among food quality, experiential value, price fairness, image, satisfaction, and behavioral intention in context of water park. In addition, the study will verify how these factors link to each other. Results show that food quality is a significant antecedent of experience value, price fairness, water park image. Also, the experiential value and water park image influence on visitors' satisfaction. Last, the satisfaction is critical predictor of behavioral intention. These findings will contribute to understand the consumers' perception about water park, and how derives the customer satisfaction and behavioral intention. In sum, present study will serve insights for industry marketers and managers in water park segment.

An water-reuse network design has drawn attention as a systematic method of reducing fresh water usage and increasing water-using efficiency. The final goal of an eco-industrial park(EIP) is accomplishing industrial sustainability and constructing water-reuse network can be a solution. When designing water-reuse network connecting various processes which consume water, the water pinch technology can be used frequently, since it simultaneously minimize freshwater usage and wastewater discharge. In this research water pinch technology is applied to develop an effective water-reuse network in an EIP. Three scenarios based on different reusing strategies were developed. The results show that the final water-reuse network can reduce the total fresh water usage more than 30%, while the water expenses decrease by 20%. It can be concluded that water pinch technology is an effective tool to optimize water-reuse network among different industrial facilities.

The purpose of this study aims to examine consumer perception and current status of water park. The Naver and Daum were used for data collection channels and the keyword 'water park' was used for data retrieval. The data analysis period was limited to the study period from January 1, 2015 to December 31, 2016 for a total of two years. First, as a result of the frequency analysis, hidden cameras, Lotte water park, arrests, suspects, gimhae were in top 5 in 2015, Lotte water park, swimming, summer, opening, admission ticket were in top 5 in 2016. Second, as a result of the connection degree central analysis, hidden camera, arrest, suspect, female, shower room were in top 5 in 2015, swimming, Lotte water park, summer and One Mount, admission ticket were in top 5 in 2016. Third, as a result of the N-GRAM network graph, the water park/hidden camera, the hidden camera/hidden camera, the suspect/arrest, the Gimhae/Lotte water park, water park/suspect were in top 5 in 2015, and One Mount/water park, Gimhae/Lotte water park, water park/admission ticket, water park/water park, water park/opening were in top 5 in 2016. Fourth, as a result of the CONCOR analysis, three groups in 2015 and two groups in 2016 were formed.

This research was planned to propose some suggestions on the management of stream water quality in the closed valley areas of the Puk'ansan National Park during July 1998 to June 1999. A closed valley area should designate whole valley area. Stream water quality monitoring should include investigation on cations ($Ca^{2+}$, $Mg^{2+}$, $K^+$, $Na^+$), anions ($Cl^-$, $SO{_4}^{2-}$) and suspended solids. A counterplan for stream water preservation and its practical application should be considered before closing a valley area. Also, the results of stream water quality in the closed valley areas in the National Park should be informed to the public. Discharged water from private areas such as a Buddhist temple, shelter, resting place, shopping center, etc. in the National Park should be checked and cleaned. We need to establish regulations on the utilization of stream side area in the park, and trails near the closed valley should also be included in the areas.

This research was conducted to investigate the influences of the solifluction soil and amount of flow on the stream water quality of the Bukhansan National Park from March to october, 2002. The average pH of stream water was higher than that caused by solifluction soil. The average electrical conductivity of upstream water was about 2.1~2.8 times lower than that of downstream water. Linear regression analysis showed that pH and amount of anion($Cl^-$, ${NO_3}^-$, ${SO_4}^{2-}$) of stream water were very significantly correlated with those at the caused by solifluction soil. Structures for erosion control along both sides of stream channel should be designed in order not to influence upon solifluction soil and stream water quality.

This study was conducted to investigate physicochemical property changes from July 1998 to August 2001 in Mt. Bukhansan National Park. Four water sampling points were selected to measure the quality of stream water in the northeastern part of the Mt. Bukhansan National Park. The results were summarized as follows; In spring, the average pH of stream water was below the first class of the river water quality standard, while it was normal level in summer. The average electrical conductivity was about 2.3~3.3 times higher in downstream water than in upstream water during spring and summer. The contents of anions($Cl^-$, $NO{_3}^-$, $SO{_4}^{2-}$) were about 1.1~7.4 and 0.4~11.4 times higher in downstream than in upstream water, respectively. These results indicate that water quality was poorer in downstream than in upstream water. We suggest that stream water in the Mt. Bukhansan National Park should be protected from impacts of snow melting mineral particles in spring season and human impacts like wastewater of point source in summer season.

This research was conducted to establish the conservation strategy of stream water quality by analyzing the factors influenced on stream water quality in the northeastern part of Mt. Bughansan National Park from July 1998 to October 2001. The number of visitors resulted in the significant increase of electrical conductivity, which affected on pollution of the stream water quality. According to the multiple regression analysis, the pH of the stream water was related to dissolved oxygen and temperature of water at the 1% significant level. The electrical conductivity of the stream water was related to number of visitors, amount of $K^+$ and ${NO_3}^-$, total amount of ions, percentages of $Cl^-$ and $Na^+$ caused by solifluction soil at the 1% significant level. The anions($Cl^-$, ${NO_3}^-$ and ${SO_4}^{2-}$) of the stream water were related to number of visitors, electrical conductivity, air temperature, hardness, amount of ${NO_3}^-$, ${SO_4}^{2-}$, total ions, percentage of $Cl^-$, ${NO_3}^-$, ${SO_4}^{2-}$, amount of $Ca^{2+}$ caused by solifluction soil at the 1% significant level. To prevent the pollution of stream water in the northeastern part of Mt. Bughansan National Park, it is recommended that the number of visitors in the park should be managed and rehabilitated rapidly by measure to eco-friendly during the spring season.
