Total forest land in Bangladesh is about 2.5 million hectare which is 17% of total land area. Bangladeshi forest is mainly classified into three categories- 1) Hill forest 2) Sal forest and 3) Mangroves. This forest land area is decreasing day by day. But in past decayed due to some policies, the total forest land area is increasing slowly. By this planning both government and the local people in the community are being benefited. This paper mainly discussed about the past, present and future trend of forest condition, forest land uses, sustainable forest planning and forest management.

Forest parks are regarded as one of the scientific ways to keep the forest sustainably developed, meanwhile deliver the benefits to the general public. The development of forest parks in China has experienced simply more than 20 years and both the exploitation and management institutions haven't been set up systematically, which, in reality, reflects as inadequate legislative and policy framework. Without the regulatory guidance and collaborating assistance of environment relating governmental sectors at both national and local levels, it's inevitable that the development of forest parks in the country would face constant problems and conflicts. Therefore, it might be helpful to sort out this conflicts and problems and further more to work out how to solve the barriers. The research in this report started with introducing the IUCN Protected Areas Categories, the overall current situations in China and compared the definition of forest parks in the country and that in international experience. It is to aim to find out the real usufruct rights conflicts during the exploitation and management of forest parks and the method used in this report is field visit, previous investigation, collecting secondary materials, interview, analysis and comparison. The research result in this report couldn't cover all the conflict situations during the forest parks' exploitation and management in China but will provide the analysis of this problem from the legal perspective. Practical application and concerning suggestion will be fully discussed in Part 5 in terms of legislative, social and environmental effects.

This study attempts to analyze the relationship between forest volume and age based on 5th NFI data and spectral characteristics of satellite imagery using ASTER sensor in Korea. Forest stand volume and age had the negative correlation with the spectral reflectance in all of the band (Blue, Green, Red, SWIR). With increasing of stand volume and age, spectral reflectance decrease. The spectral reflectance of band1 showed the highest correlation between stand volume and spectral reflectance among the VNIR wavelength. The spectral reflectance band 1, 2 (visible wavelength) and stand age have high correlation compared to other bands. The correlation coefficients between forest volume and vegetation indices have low relationship. This result indicates that the reflectance of blue band may be important factor to improve the potential of optical remote sensing data to estimate forest volume and age.

This study aimed to predict changes in forest area using a probability density function, in order to promote effective forest management in the area north of the civilian control line (known as the Minbuk area) in Korea. Time series analysis (2010 and 2016) of forest area using land cover maps and accessibility expressed by distance covariates (distance from buildings, roads, and civilian control line) was applied to a probability density function. In order to estimate the probability density function, mean and variance were calculated using three methods: area weight (AW), area rate weight (ARW), and sample area change rate weight (SRW). Forest area increases in regions with lower accessibility (i.e., greater distance) from buildings and roads, but no relationship with accessibility from the civilian control line was found. Estimation of forest area change using different distance covariates shows that SRW using distance from buildings provides the most accurate estimation, with around 0.98-fold difference from actual forest area change, and performs well in a Chi-Square test. Furthermore, estimation of forest area until 2028 using SRW and distance from buildings most closely replicates patterns of actual forest area changes, suggesting that estimation of future change could be possible using this method. The method allows investigation of the current status of land cover in the Minbuk area, as well as predictions of future changes in forest area that could be utilized in forest management planning and policymaking in the northern area.

This paper was aimed to find alternatives for coping spontaneously with the changing world forest resoures and international timber markets after UNCED in 1992. The guarantee of timber resources abroad in Korea is essential and the urgent subject, because about 90% of korean forest resources are specially under III age class and young, korean forest is in the step of improvement forestry. Therefore, some strategies were proposed for the stable guarantee of overseas timber resources.

This study was carried out to investigate members' affiliation motive to Forest Management Cooperative which is the main managemental body of the private forests and management problems of the organization to find out a solution of the problems and set active promotion plan. The questionnaire about the management of the cooperatives was done by interviewing the members at Seoha Inboh Forest Management Cooperative in Ulsan-gun, Kyongsangnam-do and Sechong Forest Management Cooperative in Chinan-gun, Chollabuk-do from July to August in 1993. Twenty interviewees were selected in the order of their business quantity on the forest from the members who reside in their villages. Integrated matters such as were members' affiliation motive, benefit after their affiliation, management system, incorporation of the organization and other issues concerning to managemental plans questioned. During the survey period, other data about management of the cooperatives were collected from the related organizations and opinions of every president of nine cooperatives in the investigated regions. The majority of the members agreed that the cooperative is an independent forest organization and evaluated the Training and Extension Service Center high. However, their participations in the cooperative such as forest technical training and cooperative forest management were low since they have not earned any income from their forest management.

Site index is the essential tool for forest management to estimate the productivity of forest land Generally, site index equation is developed and used by relationship between stand age and dominant tree heights. However, there is a limit to use the site index equation in the application of variable ages, environmental influence, and estimation of site index for unstocked land. Therefore, it was attempted to develop a new site index equations based on various environmental factors including site and topographical variables. This study was conducted to develop regional site index equations based on the relationship between site index and soil factors for Pinus densiflora. Environmental factors that obtained from GIS application, were selected by stepwise-regression. Site index Equation was estimated by multiple regression from selected factors. Four environmental factors were selected in the final site index equations by stepwise regression. It was observed that coefficients of determination for site index equations were ranged from 0.34 which seem to be relatively low but good enough for estimation of forest stand productivity. The site index equations developed in this study were also verified to be useful by three evaluation statistics such as model's estimation bias, model's precision and mean square error type of measure.

This study was carried out to find the effects of aromatherapy using natural fragrance on reducing stress and improving job satisfaction of transportation workers in the taxi industry. A total of 120 workers were divided into the experimental group and the control group according to the inhalation of the fragrance and tested for 2 weeks. After 2 weeks, the difference of emotional change, stress analysis, and evaluation of job satisfaction according to aromatherapy were compared between the two groups. The result showed that the experimental group had a higher interest in scent products than the control group and that they wanted to encounter a lot of real scents, indicating that aromatherapy caused positive interest in general scent likability. In addition, the experimental group said that the inhalation of fragrance would refresh the feeling of the passengers in the vehicle and smoothly communicate with the passengers. Especially, it showed a significant difference between the two groups in terms of tension relief, pleasure and good mood by inhalation of fragrance, indicating the positive effect on job satisfaction.

There are 3 kinds of forest managements: One of them is forest utilization management which collects abundant forest resources by felling the trees: the second of them is scientific forest management which cultivates forest resources; and the last one is emergency aid forest management, needed by the forest resources davastation, for the surposes of soil conservation and preventing the indirect damages. During the 36 years of Japanese occupation, they pillaged 600 to 800 million cubic meters of the forest resources, in the condition of the colonial system. After the emancipation from the Japanese occupation, the national soil conservation work has been practiced for 18 years without correcting the Japanese forest management (which means felling system); therefore the essential in the forest, conservation works is to get rid of imitating the Japanese pillage management so as to turn the direction of the forestry policy to the emergency aid management which means forest investment.

The present study aimed to identify the importance of forest experience activity by examining what effects forest experience activity has on primary school students. The study population consisted of 108 students enrolled as fourth graders in primary schools in Chuncheon as of November 2017. The study measured the changes in their attitude toward forest and personality from before and after forest experience activity. The results indicated that the primary school students who participated in forest experience activity showed statistically significant increase in attitude toward forest and personality. In other words, the study identified the positive effects of forest experience activity on recognizing the importance of nature and personality building. The present study aimed to test the importance and effects of forest experience through forest experience activity outside of the classroom, as well as to present the validity of promoting forest experience activity.
