  • This paper concerns Fuzzy Radial Basis Function Neural Network (FRBFNN) and automatic rule generation of extraction of the FRBFNN by means of mountain clustering. In the proposed network, the membership functions of the premise part of fuzzy rules do not assume any explicit functional forms such as Gaussian, ellipsoidal, triangular, etc., so its resulting fitness values (degree of membership) directly rely on the computation of the relevant distance between data points. Also, we consider high-order polynomial as the consequent part of fuzzy rules which represent input-output characteristic of sup-space. The number of clusters and the centers of clusters are automatically generated by using mountain clustering method based on the density of data. The centers of cluster which are obtained by using mountain clustering are used to determine a degree of membership and weighted least square estimator (WLSE) is adopted to estimate the coefficients of the consequent polynomial of fuzzy rules. The effectiveness of the proposed model have been investigated and analyzed in detail for the representative nonlinear function.

  • Background and objective: Due to the recent crisis of extinction in local areas, the mountain village promotion policy is recognized as an important task. This study examined the priorities of major policy projects in the forest sector that affect mountain village promotion. Methods: For research methods, literature search, expert advisory meetings, and a survey were conducted. The survey was conducted on 42 policy stakeholders from June 1 to August 13, 2021. The literature search was based on policy projects in the forest sector by 8 upper-level local governments including mountain villages. For questionnaire items, 173 forest policy projects were classified into 27 types through expert review, and the importance and performance of each type were rated on a 5-point Likert scale. Paired t-test, IPA, Locus for Focus model, and Borich needs assessment were used as the analysis methods, and the statistical program SPSS 21.0 was used as the analytical tool. Results: The results showed that 'creating forest-related jobs' and 'supporting cultivation of professional forestry workers' both showed high importance and performance, implying that they would show an effect in mountain village promotion. 'Creating forests for environmental improvement', 'discovering forest cultural assets' 'establishing and boosting forest tourism', 'providing forest therapy services', 'creating forest-related jobs', 'supporting community revitalization', and 'urban-rural exchanges' were found to be the types that needed improvement and concentration for mountain village promotion. In particular, 'creating forests for environmental improvement' and 'discovering forest cultural assets' were derived as priority considerations for mountain village promotion policies. Conclusion: In summary, it was found that in order to promote mountain villages, various content projects must be improved and carried out to enhance the physical environment and revitalize mountain villages.

  • Mountain side ditch is constructed at the top of cutting slopes around road and it drains the surface water that flowed from upper part. Mountain side ditch is constructed to keep away the influx of the surface water into cutting faces. However, if Mountain side ditch is constructed on the top of cutting slopes, it is cause of trouble. For example, difficulty of quality control and lack of drainage faculty. Therefore, the faculty and establishment propriety of mountain side ditch are evaluated seriously, according to the condition of ground, topography and rainfall in this paper. Results from the study for the numerical analysis of effect of mountain side ditch indicate that safety factor is enlarged about 3% at rainfall.

  • The purpose of this study is to develop promotion strategies for revitalizing mountain eco-villages through social economic support. In order to fulfill this purpose, this study analyzed operation conditions, income creation structures of 240 mountain eco-villages formed by Korea Forest Service, and reviewed systems for social economic support. As summarized in research outputs, this study confirmed that the activities of organizations for joint projects had not been properly implemented due to the absence of supporting systems following the construction of mountain eco-villages. In addition, 159 villages formed as experience villages could not be qualified for enterprise systems due to aging population and absence of network systems. As for income creation, as indicated by comparing net incomes for joint projects calculated based on the classification of village management evaluation, the average net income of 51 highly-rated villages was 22 million Won and that of 128 moderately-rated villages was 3.5 million Won. Experience-based projects and the sales of processed forestry products made by young adult associations or women's societies were major sources of income, and the absence of inner economic bases or villages' jobs caused young adults and returned farmers to focus on working for outside economic activities. Finally, this study developed strategies for mountain eco-village's social economic promotion and suggested four stages of social economic revitalization provisions.

  • The aims of this study are to imvestigate the changes seen in rural kitchens and the factors affecting the modernization of agrarian kitchen space in mountain areas, and to compare them with those in the plains. The major findings are as follows. 1) The kitchen space in mountain areas remained in the state of a combined style(depicting both western and traditional styles), while the kitchen space in the plains after the 1980s showed a tendency toward the western style. Generally speaking, the physical state of kitchens in mountain farmhouses, therefore, was at a low level in comparison with that of the plains. 2) The kitchen improvement projects of Sae-Ma-Eul Movement fostered a trend toward the western and combined style kitchens in the plains, but it did exert a little influence only on a part of the four mountain areas, and it resu]led in a combination of both styles. 3) Among the socio-demographic characteristics under consideratien. only the level of education achieved by the wi fe was found to be a determinant factor of the kitchen type in the mountain areas. but the level of education achieved by the husband and the family life cycle were two determinant factors in the plains. Under the category of family life style. the factors affecting the kitchen type in the mountain areas were cooking-heating fuel and the position of the refrigerator, while the main factors in p]ains were the place and the method of eating. cooking-heating fuel, the position of refrigerator, and numbers of family-memorials.

  • This work aims to establish the landscape ecological countermeasures to improve the sustainability of urban mountain forest and to enrich the biodiversity in twenty mountains of the Seoul Metropolitan City. Landscape ecological analysis was conducted based upon various criteria, such as area and elevation of mountains, flora, naturalized plants, vegetation, forest types, mountain trails, and public facilities. Various measures were suggested for the better maintenances of floristic diversity, introduced plants, vegetation and forest types of urban mountain forests. Sustainable recommendations for land use adminstration were developed for the preparations of a climate change-adapted urban mountain forests, as well as rational managements of ecosystem, walking trails, and public facilities within mountain forest. Rich and diverse natural vegetation as well as high floristic diversity were reported at mountains with higher elevations, larger area size, and rich landscape diversity. Mountains with low elevation, small size with easy public access, however, might require an urgent action to decrease the burdens by anthropogenic disturbances and urban development.

  • Factors for promoting the resident participation in mountain villages are suggested to introduce the activity-oriented program of green tourism using a multinomial logit model(MNLM). Direct surveying, using a structured questionnaire was performed on local residents in the different types of rural tourism villages such as mountain villages, agricultural themed villages, and the mixed types of villages. The MNLM revealed that participation intention in the program was significantly higher for males, those with lower education, and residents in mountain villages. The participation intention of the program had a negative relationship with the increase of expected problems not from the program itself, but from the results of the program such as income distribution and nature destruction. Participation intention also increased with the indirect effects of an investment by the Village Development Project, such as local cooperativeness, public mind, etc. It was suggested that to introduce the activity-oriented program in mountain villages, negative effects from the results had to be minimized, and positive effects from the indirect changes between local residents had to be maximized through better communication and policy endeavors.

  • This study develops textile designs and cultural fashion products with the image of 'Youngguchunhwa', which means the beautiful spring flowers of Jeju. Historical literature was reviewed to emphasize the authenticity of Halla Mountain and Youngguchunhwa. Consumers' responses to Halla Mountain, Baengnokdam, and Royal Azalea related to Youngguchunhwa were evaluated along with photos of Halla Mountain and Youngguchunhwa images upload on Internet during the last 2 years. The results of consumer survey and photo analysis confirmed the consumers' high preference and high association with the image of Jeju. The full-blown Royal Azaleas in the Seonjakjiwat field of Halla Mountain were used as motifs for the development of Jeju cultural products as a representative landscape showing the beautiful spring of Jeju. Six types of textile designs were developed by the repeated arrangement of the basic patterns of Halla Mountain, Baengnokdam, and Royal Azalea. Ladies' apparels products, children's wear, bags and cushions were made using oxford cotton fabrics printed with the textile designs. We suggest how pattern designs of the Youngguchunhwa image could be applicable and used for the development of other kinds of Jeju tourism souvenirs.
