Forests are valuable natural resources for people living around the mountains. In particular, the comfortable feeling or healing is one of the most important benefits obtained from forests. This healing can be possible by many aspects of forests, including the landscape, natural sounds, anions, and pleasant aromas. We focused on the volatile organics from forest causing pleasant aromas, phytoncides. Twenty phytoncides were monitored from February to September in a national tree garden (BaekDoDaeGan SooMokWon). Five sites were monitored two times per month and 20 phytoncides were detected. Borneol showed the highest annual average concentration and the order of concentration was borneol > mycene > sabinene > limonene > α-pinene. The average phytoncide concentration was relatively high in spring and summer season when the trees were physiologically active. Daily monitoring showed that the afternoon hours had higher concentrations of phytoncides than the morning hours, which may be due to the stabilized atmospheric conditions at the sites. Among the five sites, coniferous forests gave higher phytoncide emissions than broadleaf tree forests. The current study showed that forests produce several phytoncides that cause a healing effect and a forest bath may be beneficial to the health of visitors to forests.

Since 1973, we attain a successful achievement of nation-wide afforestation such as a thick forest and heaped-up leaves. However, the higher of the formation density in forest, the more dangerous to be a large-scale forest fire whenever fire occurs. According to the type of forest in the country, 42% of the forest is occupied by conifer forest that are highly flammable, and the distribution of forest age is in a transition period from immature forest to mature one. And the structure is too weak to the forest fire for the occurrence and spread because there are too many scrub and shrub trees in the forest. As a matter of course, it is on the increase of the thinning-forest that can shift the forest structure from a weak on forest fire to a strong one nowaday. In other words, thinning-forest has primary purposes such as the promotion of producing forest trees, production of excellent timbers, and build-up of public forest area. Furthermore, in some reports, the reduction of ladder fuel by eliminating the vertical/horizontal fuel in a forest and ensuring spaces in the forest can decrease the occurrence of forest fire and the risk of spread of burning as by-effect. Therefore, this study is designed to clarify the relation with the risk of forest fire by an on-spat-investigation of the characteristics of forest composition on the thinning and the non-thinning area.

This study was conducted to analyze accessibility and reduction effect of forest operations cost before and after forest road construction based on actual silvicultural operations in 5 regional forest service(8 management planning district) where forest operations was enacted consistently. The result show the accessibility and the reduction effect of the operation cost, the accessibility of forest operation area within 500 m from forest road or public road increased about 3.2 times after the forest road construction. The reduction effect of the operation cost was averagely 576,000 won/km/year. According to the results, forest road had an effect on improvement of accessibility and reduction effect of forest operation cost. This result could be offered basic information to support policy of forest road expansion.

Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

In this study, the present institution of reserved forests in Korea has been criticized through the analysis of the present situation of reserved forests in Korea, and mainly, on designation and cancellation of them because of this important institution thought as restriction of forest ownership. Reserved forest land in Korea as of the end of 1962 is 996,915 chungbo in area, or about 14.8% of the total forest land area, 6,750,324 chungbo in Korea, and we can find that the area of reserved forest land has increased remarkably since the Liberation in 1945, in comparison with about 180,000 chungbo-a little over 1% of the total forest land area, 16,000,000 chungbo, through Southern and Northern Korea till the Liberation in 1945. This fact clearly proves that Korean forests are extremely devastated since the Liberation in 1945, and in Korea we can find that reserved forest policy is very important in forest policy, consequently, reserved forest institution must be dealt with care. Moreover, the area of reserved forest land, 996,915 chungbo, which is divided into 43,820 chungbo of national forest land, 59,302 chungbo of public forest land, 893,793 chungbo of private forest land, and private forest land is excellently large, or about 89.7% of the total area of reserved forest land. In this number, we may understand the fact that reserved forests have the most influences on private forests, therefore, we may recognize that it is necessary for reserved forest constitution which is infringement of private right to be carried out carefully. From the first beginning, the institution of reserved forests is serious restriction to the forest ownership. Consequently, when the area of reserved forest land grows, it interferes seriously with the free forest management and the desire for forest own ership is decreased, at the same time, forest enterprise results in obstruction. Especially, Korean forests are destroyed extremely at present, so, intensification of reserved forest institution is unavoidable for completion of the national aim which forests have, but the author thinks that reserved forest institution must be as avoidable as possible, and we have to obtain good results by supervision of forest management which is regulated in the Forest Law. Consequently, designation of reserved forests must be minimized, and although forests were already designated as reserved forests they must be cancellated as fast as fast as possible and put them free in the owner's hands when they are in cancellation conditions. According to the provision of Article 18 of the Forest Law concrete cases designated as a reserved forest are enumerated for the purpose of maintaining the forest ownership and avoiding to give the forest authorities a free hand in order to protect forest owners from one-sided damage. Therefore, the forest authorities must not abuse the institution of reserved forests, and it is not good tendency to give only the authorities a free hand in eesignation and cancellation of reserved forests, and especially, when the forest owners object to that, establishing some legal organization like the reserved forest council in each province in order to hear about impartial opinions, and it is more suitable than administrative disposal by the same organization. The compensation of damages for reserved forests by the provision of Article 25 of the Forest Law is a different problem by forest policy, but the results of compensation of damages regulated in the Forest Law are wholly lacking up to now, the author thinks that this is caused to poor forest cover, the forest owner's unconcern and insincerity of administrative authorities. Therefore, the government must enlarge the range of compensation and minimize the forest owner's economic sacrifice, also, the government must mollify the conditions of the legal restrictions to reserved forests, and harmonize with functions of national conservation and economy. This means that it is necessary to modify the restrictive conditions for the effective utilization of forest resources within the range in which can be attained the purpose of designation, from permanent prohibition of cutting. Except the reserved forests of fish habitat, public sanitation, maintaining scenery and navigational mark ect., most of reserved forests are prohibited from cutting, and the present situation of forests in Korea are extremely devastated and those forests are not so expected in cancellation possibility in near future. Therefore, when the forest owners apply for national purchase of those reserved forests, the government had better nationalize them, protect and manage to reduce the forest owner's economic sacrifice.

Domestic timber comsumption has increased dramatically in the past few decades in this country. In addition, there is increasing demand for recreational opportunities in the forest areas and concern for watershed management and soil conservation. However, it is difficult to satisfy these demands for forest resources because many of woodland owerners who make such demands possible move from mountain villages to modern cities. Therefore, whether or not it is in the public interest to invest in rurbanization is a central policy question. This is a case study which deals with mountain village problems for making forest resources.

This study was carried out to find new perspective of forest recreation program in Gangwon-do. Gangwon-do has now 19 forest recreation sites (national forest 11, public forest 4, private forest 4) where forest interpretation, mountain bike, mountain marathon, mountain ski, forest music concert, various forest class are held. In order to develop the new programs for forest recreation program in Gangwon-do, this study considered culture program, welfare program and education program. For culture program, the experience program in traditional house, the experience in the back region and the experience in special product of mountain village were suggested. For welfare programs, the welfare programs for the old and the handicapped were shown. For education program, forest global village program and personality program were devised. According to introduction of 5 day-work per week, the population for recreation are expected to strongly increase, so Gangwon-do representing the image of tour province should improve continuous concern and various developing programs for forest recreation.

Amid public's growing interest on garden and more leisure time of modern life-style, there is an effort by the government to utilize forest as public garden. In order to utilize forests as pubic garden, a new concept of "Forest Garden" should be defined and introduced first. Furthermore, introducing a new concept requires academically analyzing values of a new concept before a new concept is widely used. Thus, we aimed to clarify the concept of forest garden by conducting Delphi technique research and factor-analysis of survey results. More specifically, delphi technique research was conducted to extract composition elements and explanation elements of forest garden. Factor analysis was conducted on the top 25 elements and 5 values were extracted as a result. They are form, scenery, ecology, history/cuture and usefulness which are essential values required of forest garden. Forest garden should have all of 5 values and be capable of function as both forest and garden which would also need continuous maintenance. We believe this study is the first one to establish definition of forest garden and more specific and realistic definitions need to be built through continuous research, 000 experiment and on-site evaluation. We also believe that this study will serve as foundation for further efforts in building forest garden in various space and in defining proper concept of forest garden.

This study was conducted to investigate the awareness tendency of the government employees who manage forest roads about problems of forest road use and how to improve them in the future using surveys. The results show there are more silvicultural operations than harvesting operations using forest roads. The main purpose of using forest roads is to transport workers; however, the road will be used more for harvesting operations in the future. The respondents wanted to be accessibility for forest operations within 200 m from road in both present and future. For silvicultural operations 1-ton vehicle is used at present, and 5-ton vehicles are expected to be used in the future. For harvesting operations 5-ton vehicle is used at present, and 10-ton vehicles are will be used in the future. The roadway width is 3 - 4 m at present, but should be 4 - 4.5 m in the future. The longitudinal gradient of roads is 7 - 10% at present, and will be below 10% in the future. The minimum curve radius of roads is 12 - 15 m at present, and will be 15 - 20 m in the future. The results provide basic data for making future forest road policies.
