With results from previous Korean studies on forest thinning, we conducted a meta-analysis on the effect of thinning on diameter at breast height (DBH) growth and carbon (C) stocks (tree, litter layer, coarse woody debris (CWD), and soils) in Korean forests. Thinning increased the DBH growth and the C stocks in soils by 39.2% and 12.8%, respectively, while it decreased the C stocks in tree by 30.9%. In contrast, thinning had no significant effect on the C stocks in litter layer and CWD. The DBH growth and the C stocks in tree showed significant correlations with thinning intensity and recovery time. The C stocks in litter layer correlated with recovery time while those in CWD and soils did not show significant correlation neither with thinning intensity nor with recovery time. Regression models of the DBH growth and the C stocks in tree were developed to quantify the effect of thinning intensity and recovery time. An integration of the regression model of the tree C stock into forest carbon models is expected to be essential to quantify the effect of thinning on the C stocks in litter layer, CWD, and soils. We also suggested expansion of study species, long-term and frequent monitoring, and investigation on understory vegetation in order to elucidate changes in Korean forests following thinning practices.

Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 536~542
DOI : 10.14578/jkfs.2015.104.4.536
This study was examined for the growth response of tree diameter and volume to thinning treatments from different thinning intensities using three long-term thinning trials for Japanese Evergreen Oak (Quercus acuta Thunb.) stands in Wando island, Korea. After thinning in 1999, annual tree growth of diameter and volume was highest in heavy thinned stands for individual tree and this growth pattern of thinning response showed similar tendency to the individual tree growth response in light thinned stands. By increasing diameter growth, the value of H/D ratio (HDR) as an indicator of stem form was properly decreased and improved up to 80%. Although there is significant growth response of basal area in both heavily and lightly thinned stands, the growth potential both of heavily and lightly thinned stands in total stand volume is not likely to reach at the level of unthinned stands because of basal area growth loss associated with both light and heavy thinnings.

Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 543~548
DOI : 10.14578/jkfs.2015.104.4.543
We studied the genetic impact of natural regeneration practices, such as Single seed tree, Group seed tree, Patch clear cutting and Alternate strip clear cutting systems, by comparing the nuclear microsatellite(nSSR) variation of post-practice natural regeneration one-year old seedlings of Pinus densiflora to that of pre-practice mature trees. The levels of genetic diversity of seedlings (A=13.6,
=0.597) were similar to those of mature trees (A=13.4,
=0.598) and the differences in the level of genetic diversity between seedlings and mature trees for each of the practices were not statistically significant. The degree of genetic differentiation between seedlings and mature trees was very low (
=0.002) and the pairwise
values between seedlings and mature trees for all practices were less than 0.01. Overall, the natural regeneration practices appeared to have only minor impacts on the genetic diversity and the genetic composition in the studied P. densiflora stands. For a better understanding of the genetic effects of natural regeneration practices, subsequent studies such as temporal genetic variation of seedlings formed by crossing among post-practice mature trees should be considered.

Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 549~557
DOI : 10.14578/jkfs.2015.104.4.549
Novel cpSSR primers were developed based on the sequence information of the Pinus koraiensis chloroplast genome. A total of 30 cpSSR loci were detected in the chloroplast genome, and a total of 30 primer sets flanking those loci were designed. All primer sets were successfully amplified for chloroplast DNA in P. koraiensis. The cross-species transferability of the 30 primer sets was considerably high in P. pumila (100%) and P. paviflora (97%) belonging to the same Subgenus (Strobus) of P. koraiensis. Meanwhile, the transferability was relatively low (73%) in P. densiflora and P. sylvestris belonging to Subgenus Pinus. A total of 13 cpSSR loci out of the 30 loci were polymorphic in the Mt. Jumbong population of P. koraiensis. The mean of haploid diversity(H) was 0.512. The number of haplotypes(N) and the haplotype diversity(
) were 25 and 0.992, respectively. Of the 25 haplotypes, 22 were unique in the analyzed population. The unique haplotypes differentiated 22 individuals (79%) from the total of 28 individuals. In conclusion, the novel cpSSR primers developed in this study would be applicable to other Pinus species, especially the subgenus Strobus, and provide a high level of polymorphism for the study of genetic variation of P. koraiensis.

Oh, Sung-Il ; Park, Yunmi ; Kim, Mahn-Jo ;
Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 558~563
DOI : 10.14578/jkfs.2015.104.4.558
The effects of pre-treatment methods (water cooling, water cooling+ozone, precooling+microbubble, water cooling+ozone+microbubble) after harvest on the quality of 'Mipung' chestnut were studied. Changes in quality of chestnut were greater precooling treatments effect than washing treatments. But, decaying rate and total microorganism were significantly differences among treatments. The decaying rate after 12 weeks storage was highest at 20.0% in non-treatments and lowest at 3.3% in water cooling+ozone and water cooling+ozone+microbubble treatments. The total microorganism immediately after washing treatments was in the order non-treatments (4.4 log CFU/g) > water cooling treatments (4.0 log CFU/g) > water cooling+ozone+microbubble treatments (3.5 log CFU/g) > water cooling+ozone treatments (3.4 log CFU/g) > water cooling+microbubble treatments (3.3 log CFU/g), and after 12 weeks storage was increased within 4.7 to 5.9 log CFU/g. Thus, the washing treatments, especially ozone treatments, extended the shelf-life of the 'Mipung' chestnut by inhibiting the decaying.

Lee, Kyung Joon ; Song, Jae Do ; Lee, Kyu Hwa ;
Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 564~577
DOI : 10.14578/jkfs.2015.104.4.564
The objectives of this study were to investigate the possibility of establishing a tree nursery at Saemangeum reclaimed land and to classify landscape trees based on the salt tolerance. A tree nursery (2.0 ha) was made in Gunsan Okgu area in 2012 with underground drain lines on the reclaimed land established in 2010. Salt content of the nursery soil within the 60 cm depth in 2013 was 5.13 dS/m and 8.20 dS/m for the pre-desalinated and non-desalinated lands, respectively. Thirty-six woody plant species (22 tree species and 14 shrub species at ages of 1 to 4) with a total of 3,943 individuals were planted in early April, 2013 and their growth performance was monitored until September of the same year. The average survival rate of the transplanted plants was 71.4% in late September, suggesting the high possibility of establishing a tree nursery at the reclaimed land. Based on the survival rate and tree vigor (amount of healthy leaves and crown development), the following 17 species with some salt tolerance were classified into three groups: "salt tolerant group" (3 species, Tamarix chinensis, Cudrania tricuspidata, Ilex serrata), "recommended group" (5 species, Pinus thunbergii, Albizia julibrissin, Ligustrum obtusifolium, Rosa rugosa, Pleioblatus pygmaeus), "plantable group" (9 species, Zelkova serrata, Hibiscus syriacus, Elaeagnus umbellata, Sorbus alnifolia, Sophora japonica, Metasequoia glyptostroboides, Quercus acutissima, Ulmus parvifolia, Robinia pseudoacacia). Seven tree species that had been adapted to the reclaimed land for three to four years before being transplanted to new reclaimed land in Gunsan Okgu area showed average survival rate of 98%, suggesting that pre-conditioned trees would survive well in the reclaimed land.
Two-Year Estimates of Mating System in Seed Orchard of Pinus densiflora Revealed by cpSSR and nSSR Markers
Kim, Young Mi ; Hong, Yong Pyo ; Park, Jae In ;
Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 578~587
DOI : 10.14578/jkfs.2015.104.4.578
Nuclear SSR (nSSR) and chloroplast SSR (cpSSR) markers were analyzed to assess the parameters of mating system in seed orchard, such as outcrossing rates, the number of potential pollen contributors, paternal contribution rates, degree of pollen contamination, and biparental inbreeding (
). In 2006, 2007, seeds were collected from the seed orchard of Pinus densiflora, established in 1977 at Anmyeon island. Estimates of outcrossing rates ranged from 94.9 to 100% (mean 98.9%) in 2006 and from 91.2 to 100% (mean 97.7%) in 2007 on the basis of the analysis of cpSSR haplotypes and from 90.3 to 100% (mean 95.9%) in 2006 and from 81.6 to 100% (mean 95.3%) in 2007 on the basis of the analysis of nSSR genotypes. By cross checking of both DNA markers, mean cumulative outcrossing rates of 100% and 98.9% were estimated in each year. Mean contamination rates were estimated as 48.9% and 42.4%, respectively. On the basis of cpSSR haplotype observed in each seed, paternal contribution rates (the number of pollen contributors) were estimated as 0.458 (mean 16.2) in 2006 and 0.512 (mean 14.8) in 2007. In conclusion, considering pretty high level of outcrossing rates observed in a seed orchard, there might be little to be influenced by inbreeding depression for genetic potential of the seeds induced by selfing. Estimates of the mating system parameters obtained from the two reproductive years were not statistically different, which revealed stable genetic quality of seeds produced in different years. Observed results from this study may provide useful information for the management and establishment of the seed orchard of the progressive generation.

This study was carried out to identify the reasons of the landslide by land creeping in South Korea in order to provide basic information for establishing the management plan for prevention. Total 29 sites of landslide areas caused by land creeping were observed in South Korea. Among them, the soil-composition of most frequent landslide areas occurred by land creeping was colluvium landslide as 75.9% (22 sites), followed by clay soil landslide as 10.3% (3 sites), bedrock landslide as 6.9% (2 sites), and weathered rock landslide as 6.9% (2 sites). According to the types of parental rocks, the investigated landslide areas were divided into 3 types: 1) metamorphic rocks including schist, phylite, migmatitic gneiss, quartz schist, pophyroblastic gneiss, leucocratic granite, mica schst, banded gneiss and granitic gneiss, 2) sedimentary rocks including limestone, sandstone or shale and mudstone, 3) igneous rocks such as granite, andesite, rhyolite and masanite. As a result, it was noticed that the landslides occurred mostly at the metamorphic rocks areas (13 sites; 44.8%), followed by sedimentary rock areas (12 sites; 41.4%), and igneous rock areas (4 sites; 13.8%). Looking at the direct causes of the landslide, the anthropological activities (71%) such as cut slopes for quarrying, construction of country house, plant, and road, farming of mountain top, and reservoir construction were the biggest causes of the landslides, followed by the land creeping landslides (22%) caused by geological or naturally occurred (22%), and cliff erosions (7%) by caving of rivers and valleys.

DOI : 10.14578/jkfs.2015.104.4.598
This study analyzed the characteristics of the disaster occurrence and disaster-prone zones on the 85 forest roads in the Jeollabuk-do area by referring to their forest environment factors. The on-site survey reveal the types of forest road disasters as follows: erosions of cutting slopes 54.1%, erosions of the filling slope 35.3%, collapses of cutting slopes with filling slope 9.4%, and erosions of road surface 1.1%. Disasters most frequently occurred in the vertical location (the hillside) and the horizontal location (the slope), and the forest factors affecting the road disasters were degree of cutting slopes in
, degree of filling slopes in
, and the soil texture of SiL. The most significant factors on the most frequent occurrence of forest road disasters were forest type of coniferous, slope aspect northeast, forest age of plantation and felling area, and rainfall in 1601~1700. An analysis of the occurrence of the forest road disasters in the Jeollabuk-do area showed a positive correlative relationship with the following factors of the forest environment within a 1% error: degree of cutting slope in
, annual accumulation rainfall in 1601~1700. and showed a positive correlative relationship with the following factors of the forest environment within a 5% error: horizontal location of valley, forest type of coniferous, length of slope more than 20 m, forest age of plantation and felling area, soil texture of SiL.

Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 607~614
DOI : 10.14578/jkfs.2015.104.4.607
This study aims to analyze the current status of timber production operation and the effects of the forestry mechanization projects on timber production. In order to increase the domestic timber production, it is necessary to propel forestry mechanization project, improve policy and institution, broaden forest-road network, enlarge the number of forest workers, enhance timber production and supply system, provide forestry machines, establish forest operation system, and train forest workers. In addition, the reestablishment of policy goals, the consistency of policy, and the rearrangement of laws and institution are considered more important. To improve the results and effects of forestry mechanization project, it is necessary to drive of forestry mechanization project, the spread of forestry machines, the cultivation of trainer ability, the development of training materials, and the teaching of field skill. In order to meet timber buyersí preference, timber needs to be produced through whole tree logging operation system. Expanding the proportion of domestic timber among total timber demand in Korea requires price competitiveness, and the supply ability of high quality product from the perspective of length and width.

DOI : 10.14578/jkfs.2015.104.4.615
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.

Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 622~631
DOI : 10.14578/jkfs.2015.104.4.622
This study was conducted to clarify the distribution and fragmented points of mountain range and to select priority points for restoration by assessment in Daejeon. There were ten Semaek of mountain extended from three Jimaek in Daejeon. As a result of overlapping the main mountain ridge with a network of roads, twelve points out of total thirty-one fragmented points were chosen as practical points for restoration. We developed index and model to assess twelve practical points for restoration. All points were classified into three grades, four points of grade I, five points of grade II and three points of grade III. From this study, we proposed differentiated restoration plan for each grade. Further studies on development of more objective assessment and detailed methodology should be needed to prepare effective restoration plan.

DOI : 10.14578/jkfs.2015.104.4.632
Working in the forest would require a wide range of skills and experience for specific tasks which involve with a high level of risks to worker's safety. However, there has been a concern on the current standard wage system for forest workers because it does not effectively reflect the characteristics of typical working conditions in the forest. In addition, the current standard wages for forestry workers was estimated based on the construction industry's wage system. Therefore, the purpose of this study is to assess a current wage system through the mail survey method and to develop a new wage system for forest worker which effectively reflects skill sets and experience required for successful completion of the work in the forest. We mailed the survey questionnaire consisting of 19 questions to 659 forest workers and received 188 responses resulting in a 28.5% response rate. The results showed that the current average optimal wages of forest worker, special worker and feller were 97,680won/day, 127,559won/day and 152,403won/day, respectively though there were variations depending on the regions. In developing the new standard wage system, this study suggest the current work types(worker, special worker and feller) could be divided into 5 work types (forest-environment workers, forest operations in beginner, forest operations in intermediate, forest operations in advanced and forest equipment operator) reflecting specialty of forest operation thereby stabilizing the new wage system for forest workers.

National forests have been assumed to do a leading role in carbon sequestration and creating forest resources since society demanded it due to climate change. Therefore, it is needed to check whether a national forest management plan and its evaluation are implemented effectively. As an effective planning and management is to be ensured on the basis of proper evaluation system, this research suggests to improve the evaluation system by analyzing it theoretically. Improvements for national forest management plan and its evaluation are as follows: (1) adjusting evaluation goal and time; (2) giving weighting to each work when planning; (3) writing details of change in planning and its grounds; (4) using the national forest management information systems to integrate these evaluation methods and result. Since to predict future changes in forests and achieve sustainable forest management begins at the reliable evaluation for overall process of the implemented project, the significance of this study is in proposing the improvement of evaluation system for national forest.

Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 649~656
DOI : 10.14578/jkfs.2015.104.4.649
The objective of this study was to analyze the optimal thinning regimes for timber or carbon managements in Cryptomeria japonica stands of Hannam Experimental Forest, Korea Forest Research Institute. In solving the problem, PATH algorithm, developed by Paderes and Brodie, was used as the decision-making tool and the individual-tree/distance-free stand growth simulator for the species, developed by Kwon et al., was used to predict the stand growth associated with density control by thinning regimes and mortality. The results of this study indicate that the timber management for maximum net present value (NPV) needs less number of but higher intensity thinnings than the carbon management for maximum carbon absorption does. In case of carbon management, the amount of carbon absorption is bigger than that of timber management by about 6% but NPV is reduced by about 3.2%. On the other hand, intensive forest managements with thinning regimes promotes net income and carbon absorption by about 60% compared with those of the do-nothing option.

This study examined the effectiveness of 'Forest Therapy (FT)' from the biological, neurocognitive and psychosocial perspectives. Adolescents who were classified as potential internet addicts took part in a FT program for two (once or twice) or three days. Before and after participating the program, Serum Brain-derived neurotrophic factor (BDNF), Comprehensive Attention Test (CAT), Children's Depression Inventory (CDI), and State Anxiety Inventory (STAI) were measured. It was found that FT led to positive consequences, indicated by increased serum BDNF, improved CAT performance, reduced internet use desire, greater resilience, and better social relationship. In addition, FT was partially effective in alleviating state anxiety level, when the participants were classified in accordance with FT exposure lengths. Overall, this study provides evidence that FT reduces symptoms related to internet addiction and promotes various qualities required for well-being.

Min, Kyung-Taek ; Koo, Ja-Choon ; Kim, Myeong-Eun ;
Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 668~676
DOI : 10.14578/jkfs.2015.104.4.668
The objective of this paper is to elicit some policy implications to promote agroforestry in South Korea from the consumers' perspective. We conducted internet survey to 640 urban households about the recognition of forest farming products. Consumers purchased forest farming products for their nutrition, medical function, and safety and regarded them as higher quality than crops cultivated from agricultural land. Consumers preferred forest farming products but revealed no difference in recognition of naturally-grown products. Consumers buying forest products prioritize the quality and medical function among attributes. Among consumers as their income increases, they regard naturally grown products more important than price and freshness. Therefore, to promote agroforestry in South Korea, certification for naturally-grown products to win the consumers' trust and the
industrialization by combining experience and green tourism program must be considered.

DOI : 10.14578/jkfs.2015.104.4.677
This study analyzed a long-run growth trend of the forestry sector in the Republic of Korea, and forecasted the potential growth in the future after investigating main drivers of growth in the forestry sector through growth accounting analysis. Based on results, we finally suggested a direction to go forward in order to achieve a sustainable growth in the field. After Asia financial crisis, the growth rate of the forestry sector was getting stable with the fast recovery of Korean economy. While the main drivers of growth in the field was labor and capital accumulation in 1980s and 1990s, the main driver of growth has been the increment of capital accumulation since 2000. As the result of our analysis for forecasting the potential growth in the field, the contribution of labor, capital, TFP in total growth is expected as 0.09%, 1.58%, and -0.01%, respectively. The potential growth rate of the forestry sector during 2012-2020 is predicted to be 1.65% and the total production will become 36.25 trillion won.

Journal of Korean Forest Society, volume 104, issue 4, 2015, Pages 685~696
DOI : 10.14578/jkfs.2015.104.4.685
This study intends to evaluate visual preference and image for 10 types of forest sceneries which have own distinct characteristics without overlapping each other among 22 types of beautiful forest sceneries based on Korea National Parks. Z scale and paired comparison methods were used to analyze visual preference for forest scenery, and SD scale method was also adopted to assess visual image for forest scenery. Experiments were conducted with 3 different university students groups. The results of this study can be summarized as follows. First, the evaluation results of Z scale (N=70) and paired comparison (N=64) methods show similar visual preference for different types of forest scenery. 'Scenery inside forests' and 'valley and rock' sceneries have the highest level of preference, and 'panorama of ridges', 'ridge of curious rock peaks', and 'waterfall and cliff' also have relatively higher preference level than others. However, 'community of dead trees' has the lowest preference in forest sceneries. Second, the factor analysis outputs of the image scores for beautiful forest scenery types by SD scale (N=66) show 3 factors of 'mysterious charm', 'colorful sense', and 'vividness/variety'. Examined the variables of forest scenery types for each factor, the image of 'mysterious charm' is based on the sceneries of mountain ridges, the image of 'colorful sense' is focused on the sceneries of color-expressed sense of the season, and the image of 'vividness/variety' is based on the sceneries of waterscape and curious rock peaks.
