As a part of research to improve the satisfaction of residents on natural recreation forests near/within a city, the recognition of the residents was investigated and evaluated by using five-point Likert scale or frequency analysis for the plan of Mt. Wora natural recreation forest in Jinju city, which included the awareness, importance, preference, and visit intention of the residents. Until now, the personal goals of most visitors at Mt. Wora have been exercising or walking, and showed different from those of visitors at recreation forests with lots of recreational facilities and natural resources. Also the satisfaction was 3.6 and tended to be lower than that at natural recreation forests. The awareness and necessity of natural recreation forest were 3.3 and 4.0 respectively. As a result, the awareness was lower than the necessity though most respondent (84.5%) had already visited and experienced natural recreation forest before this survey. In the importance of facilities and programs, recreation/relaxation places, family accommodation, education, and leisure and sports were 4.2, 3.7, 3.7, and 3.4 respectively. The result shows a feature that the education was equal/similar to the family accommodation and the leisure and sports was over 3.0. In the preference of the types of accommodation and outdoor stay, the frequency of bungalow was 57.4% and higher than others. And then the frequency of autocamping and glamping were 36.5% and 32.9% respectively, and higher than that of camping. It indicates that users prefer more convenient types to typical/common types. The awareness and necessity of forest culture education were 3.1 and 4.1 respectively. The awareness of leisure and sports facilities was 3.2. The preference of adventures (zip line, eco-adventure etc.) was 3.4 and higher than those of others.

This study was conducted to investigate the changes in the frequency of use, users’ behaviour and satisfaction of Seonhaksan and Bibongsan mountains near city center improved through the park and green spaces projects implemented by Jinju City Hall from 2004 to 2016. The number of visitors per day was measured by observation surveys in 2004 and 2016. The users’ behaviour and satisfaction were measured by questionnaires in 2004 and 2017. The collected data were analyzed by frequency analysis and independent sample t-test. The number of visitors per day increased about two times on weekdays and more than 2.5 times on weekends in 2016 than in 2004. Relatively the number of male visitors increased more than that of female visitors. The share of elderly visitors has increased and the number of visitors who live out of 1 km radius has increased. The goals of visit were changed from hiking or walking to various recreational activities, and the number of users visiting by car increased. The number of visits and the duration of visit has decreased. The inconveniences of trails and exercise facilities were significantly reduced, and the necessity of family recreational facilities fulfilled. The necessity of outdoor learning facilities and programs has not been recognized. Comprehensively, the results indicate that the recreational quality of Seonhaksan and Bibongsan mountains has improved. Further implementation of target-oriented parks and green spaces will be necessary in the future.

The purpose of study was to find critical problems which needed urgent solution and give policy priorities on the damaged forest lands close to cities through analysis of public perception. A survey was conducted of forest land users at the entrance of Mt. Bibongsan. And the survey consist of the questions of socioeconomic background on its nominal scale and the questions of cultural value, problem, solutions, maintenance methods and main body to drive related policies for the highly damaged Mt. Bibongsan on 5-point Likert scale. The 86.7 percent of respondents were in the over forties’ age and 65.3 percent visited the forest land more than two times a month. The early five categories’ averaged values were ranging from 3.54 to 3.89. Among the categories, ‘Solutions of the damaged forest land,’ ‘Mt. Bibongsan Restoration method’ and ‘Main body to drive policies’ showed statistical significance in their internal variables from Kruskal-Wallis test. But they did not show exact the ranking between variables and ranking. So thirty variables were reclassified to five categories (F1 ~ F5) by factor analysis. And with using this categories as dependent variables, five regression models were established respectively. The result showed that ‘Problem of Mt. Bibongsan (F1a)’ could be severer by illegal facilities and soil erosion from farming and ‘Solutions of Mt. Bibongsan (F1b)’ took the restoration of forest and destruction of aged houses on hillside as priories. For ‘Historical resources restoration (F2)’, it required to find folk tales and commune with citizen more from restoration of historical resources. To enhance ‘Mt. Bibongsan’s cultural value (F3)’, it was very important to consider citizen’s emotion linked to Mt. Bibongsan. As a ‘Main body to drive policies (F4)’, citizen’s active participation is more effective to policy enforcement. ‘Maintenance policy projects (F5)’ took restoration forest from farmland and forestscape improvement on city-viewed part as urgent projects.

Experiments were conducted to evaluate a experimental model developed for the protein removal by foam separation. The foam separator was operated in well-mixed tank which would be considered as a completely mixed condition. The feasibility of foam separation to remove protein from sea water was investigated. Protein removal characteristics of the foam separator were obtained by batch experiments. To find the effect of the operating parameter to protein removal rate, the foam separation was carried with variation of initial protein concentration and superficial air velocity. The result indicated that the protein removal efficiency was increased with increasing protein concentration and superficial air velo챠ty. The relationship between operation parameters and protein removal rate were evaluated by non-linear regression as the form of exponential function. Using both relationships, the simplified model was determined. The simplified foam separator operation model was verified by the batch operation. The simulation results showed a good relationship with the experimental data.
