The purpose of this study is to survey the current awareness of local officials and to give a proposal that can establish the meaningful directions for the forest landscape policy. The data for this study was collected with questionnaires. Total 232 questionnaires were launched and valid 105 questionnaires were used for analysis. As a result of these data analysis, we found out that their awareness of the importance of forest landscape was high and they thought forest landscape plan was needed. However supply of the information and data such as guidelines to improve forest landscape condition was not enough. Through the IPA method, we had 15 properties of forest landscape policy were settled. It show us what needs to be kept up the good work, what needs to be concentrated here, what the low priority are, or what the possible overkill are. We finally suggest that direction of forest landscape management should be established based on above investigation.

This study was aimed to specify health-related push and pull factors in mountain climbing and provide effective management strategy for mountain-based recreational setting through the identification of the reciprocal relationship between the push and pull factors. The results of survey by 440 mountain climbers at Mt. Dobong, Mt. Bukhan, Mt. Kwanak, and Mt. Cheonggye showed that three dimensions were respectively derived from health-related 15 push items and 11 pull items; therapeutic care, mental health, physical fitness in push factors and cultural, socio-economic, and natural environment in pull factors. According to an analysis of influence between push and pull factors, natural environment was reported to be the greatest influencing pull factor on therapeutic care and physical fitness, and socio-economic environment was on mental health.

The overall purpose of this study was to investigate pedestrians and commercial business men and employers' recognition on management of street trees and green spaces along street sides. The followings were main results of this study. Both pedestrians and commercial business men and employers mostly perceived positive influence of street trees on urban environment and their business. In addition, pedestrians gave higher scores of positive influence of trees function than those of commercial business men and employers. Pedestrians showed strong intention to participate management activities of street trees or green spaces. This study indicated that negative perception on street trees came from improper management rather than existence of street trees. Therefore, more intensive management actions are needed.

Automobile credit business has developed rapidly in recent years, and corresponding default phenomena occur frequently. Credit default will bring great losses to automobile financial institutions. Therefore, the successful prediction of automobile credit default is of great significance. Firstly, the missing values are deleted, then the random forest is used for feature selection, and then the sample data are randomly grouped. Finally, six prediction models of support vector machine (SVM), random forest and k-nearest neighbor (KNN), logistic, decision tree, and artificial neural network (ANN) are constructed. The results show that these six machine learning models can be used to predict the default of automobile credit. Among these six models, the accuracy of decision tree is 0.79, which is the highest, but the comprehensive performance of SVM is the best. And random grouping can improve the efficiency of model operation to a certain extent, especially SVM.

The objectives of this study were to gauge the extent of the forestry business through establishing the definition of forestry industry from the perspective of economic convergence and to analyze key components that affect each growth phase of a forestry business entity by classifying them. A total of 1,397 "sixth-sector industry" management entities were certified by the Ministry of Agriculture, Food, and Rural Affairs in South Korea from 2012-2017. Of these, 259 (18.5%) were in the forestry sector. In this study, the 259 forestry management entities were further classified into three phases based on sales distribution: entrance, development, and maturity. The entrance phase (<100 million KRW), development phase (>100 million and <1 billion KRW), and maturity phase (>1 billion KRW) constituted 33.2%, 55.4%, and 12.4% of the total 259 entities, respectively. The results showed that most of the management entities were either in the entrance or development phases, and only a small portion was in the maturity phase. To identify the key variables that affect each of the phases, chi-square analysis was used. We designed the "sixth-sector industry" type as an independent variable, whereas selected region, business organization, manager age group, forest product, processing type, and service type were designated as dependent variables. The results of the analysis showed that the processing and service types influenced all three developmental phases. Moreover, as the phase advanced, processing type showed a higher proportion of health-functional ingredients, such as powder or extract from forest products, which enable to develop and produce a variety of products. Service type also changed from simple experience to integrated experience tourism and finally to tourism education. Distribution and sales channel also turned out to be a significant factor during the development phase. This study provides the basic information needed to guide government support in the implementation of a formal forestry business through convergence as well as to increase the efficiency of business management.

This study was carried out to investigate the optimum condition for sap exudation of Acer mono Max. tree in a site of Mt. Jiri, Hamyang-gun, Korea. Amount of sap exudation, air temperature, relative air humidity, tree diameter at breast height (DBH) and sugar content in sap were monitored during the early springtime, and correlation analysis of several factors was carried out to explain tree-to-tree and date-to-date variations in sap exudation. The correlation, linearlyassociated between DBH and sap amount, was strengthened as daily amount of sap increased, but there was no significant tree-to-tree variation in time and period for sap exudation. When amount of sap exudation was above 10 liter/day, the mean air-temperature was averaged at $1.2{\pm}1.6^{\circ}C$, the minimum at $-4.3{\pm}1.5^{\circ}C$ and the maximum at $11.8{\pm}1.9^{\circ}C$. The maximum air temperature and mean air temperature were significant (p < 0.05) factors for amount of sap in correlation analysis to explain date-to-date variation in sap exudation. Sucrose content in sap was in the range of 1.5 and 1.7% during exudation days, but sharply reduced to 0.6% level at the end of exudation period.

This study was conducted to contribute to propose the improvement by looking into the use of private forest support system and then analyzing the status of support system and problems among forest owners. The study result showed that the recognition of private forest support system was 57.8% in sincere forest managers and 47.6% in forest successors, but only 17.6% in forest owner. The application experience was 79.2% in sincere forest managers, and 58.6% in forest successors, but 28.6% in forest owner which was significantly low as was shown in the recognition. Response on 'not knowing the support system' as the reason they were not able to ask for support was 36.1%, 43.0%, 78.6% in sincere forest managers, forest successors, and forest owner respectively in that order, which were the same results with the recognition. In the contrast, the effects of support for private forest management were higher in forest owner than sincere forest managers and forest successors, and overall level of satisfaction was also 28.5% in sincere forest managers and 36.8% in forest successors and 41.5% in forest owner. It turned out that forest owner who had somewhat low numbers of application had rather high satisfaction on overall management. Therefore, in order to attract active forest management from forest owner who take up most of forest owners in South Korea, the recognition on private forest support system is needed to improve and the local government and the Forestry Association should come up with active plans for public relations and support.
