This study was carried out to examine the perceptions of consumers and forest product manufacturers in South Korea about forest certification and to identify their willingness-to-pay for certified products by personal interviews. Sixteen percent of interviewees knew and heard about forest certification. However, fifty-six percent of interviewees had an intention to participate in forest certification system. The consumers' group can be described in relative terms as the male of 30 age bracket. The average price premium charged to consumers was higher than one paid to manufacturers, and thus manufacturers are willing to include the additional costs for certified products.

This study was carried to analyze the structural change of interrelationships between the forestry including forest product processing and the other industrial sectors. The interindustry tables (19 setors) were drawn with the aid of the interindustry table published in 1970, 1975 and 1980 in connection with the forestry and forest product processing. In addition, the input coefficient and inverse matrix coefficient were calculated in the light of the 19 sector of interindustry tables. Owing to the change of economic structure during the period of 1970-1980, the importance of forest in Gross National Product has been decreasing. But it has shown that forestry is a kind of original industry having a great deal of intermediate demand which is constantly increasing. Therefore, forestry could be regarded as a supply industry to other industries. In addition, the import coefficient of forestry products in larger than that of other industries and it keeps increasing.

Objective of this study is to provide basic information for developing more differentiated and targeted forest healing policy and Korean medical healing programs grounded on consumer preference for forest based Korean medical healing tourism products. The internet survey(CAWI) by percentage quota sampling with 400 Seoulite ages over 30 by the age, area, and gender was conducted, and 317 samples were used for a final analysis. 61.5% of the Seoulite associated 'forest bath/walking in the woods/tree' with an image of a forest based Korean medical healing tourism product, and preference for the product and the intention to use were positive at the percentages of 72.9% and 67.5%, respectively. Preferred areas were Seoul/Gyeonggi-do(53.5%) and Gangwon-do(38.8%). 'Stress solving and refreshment', 'taking a forest bath and a walk', and 'maintaining and promoting health' were the main purposes of the use. As for a therapy, 'walking therapy' was most preferred, and 'ergotherapy' was the next. First priority as for a use facility was 'healing trail', and 'professional medical facility' ranked second. Although important decision attributes were ' cost of use', 'food', and 'friendliness of medical staff', all the other sets of attributes related to use convenience, quality of medical service and tourism activities also recorded high, which forecasts higher consumer expectation for the product. As the result showing differences in consumer preference by the demographic segmentation, differentiated and segmented consumer needs should be considered when planing and managing a product. The scope of the study is limited to a demographic segmentation which is a basic stage of understanding consumer preference, therefore more detailed future researches on complicated and multi-dimensional consumer needs are required.

This study was carried out to examine the e-Business status of Korea Forest Product Industries and to propose the development. The use level of e-Business in korea forest product industries have stayed in internal company information network integration stages. But lots of companies located in the insufficient of e-Business models, the lack of qualified staffs, and the shortage of e-Business operating technology and implementation. As the result of this study, the followings must be considered; 1. For the promotion of e-Business use, it is needed to maintain price competitiveness, quality competitiveness, and market correspondence capacity. 2. For the settlement of e-Business models, it is important to connect information network among cooperation companies as like forest products standardize, common database, and standard electronic catalogue. Also, it needed developing program to strengthen the competitiveness of forest product industries, expanding to outsourcing and affiliated companies.

In order to prevent global warming according to fossil fuel use, countries around the world are making efforts through the Kyoto Protocol and the Paris Climate Change Convention. In addition, in order to prepare for high oil prices, researches such as the development of various renewable energy are being conducted. At present, the domestic production rate of energy sources in Korea is low at 18.1%, and power plants using forest biomass are being constructed to meet the domestic situation where 63% of the land is a forest. In 2015, the global production of wood pellets, a raw material for wood-based biomass power generation, was 28 million tons, up 7.7% from 2014, and has increased tenfold over the last decade. This is a result of increased demand for biomass. Korea is also increasing every year. However, biomass fly ash, an industrial by-product generated by biomass energy generation, is now being disposed of entirely, and there is little research to utilize it. Therefore, this paper will use biomass fly ash, an industrial by-product, which is currently being discarded due to a lack of separate treatment methods, as an admixture concept to contribute to solving environmental problems, developing new admixtures, improving quality, and seeking recycling plans.

Effect of pre-treatment and compression ratio on specific gravity (SG) and dimensional stability improvement of three lesser-used wood species from natural forest area of North Kalimantan Province, Indonesia had been investigated. Hot soaking at 80℃ for 3 hours within 2 and 5% of boron solution was applied as pre-treatment, while compression ratio applied was 20 and 40% from the initial thickness. Densification was conducted using hot pressing machine at 30 kg/㎠ of pressure and 160℃ of temperature for 15 minutes. Specific gravity was measured gravimetrically, while dimensional stability was evaluated through thickness swelling and water absorption as the indicator. Results show that SG of densified wood was influenced by wood species and compression ratio, but not by pre-treatment applied; while dimensional stability was influenced by wood species, compression ratio, and pre-treatment. Specific gravity and water absorption of densified wood was improved significantly. Specific gravity increased 28.86-63.03%, while water absorption decreased 12.80-15.89%. Thickness swelling of 20% densified wood was lower than that of 40% densified wood.

This study applied the portfolio approach as a means to provide decision-making information for the establishment of the optimal production plan for non-timber products. The target items of non-timber forest product were Chestnut, Jujube, Walnut and Astringent Persimmon. The data used in this study were the annual report of forestry production cost survey which contains the annual production, annual gross income, and annual product cost from 2008 to 2013. These data were used to calculate the expected return of non-timber forest product. The objective function in the portfolio models was to minimize the expected return volatility, called risk and the constrain was to achieve the minimum expected return rate. Results indicated that the production ratio of the nuts and fruits in 2013 was 7% for Chestnut, 20% for Jujube, 5% for Walnut and 68% for Astringent Persimmon. Furthermore, portfolio presented that the production ratio was 10% for Chestnut, 9% for Jujube, 3% for Walnut and 78% for Astringent Persimmon in the near future. The cause was analyzed due to maintain stable production and income of Astringent Persimmon and Chestnut. Meanwhile, the revenue of Walnuts and Jujube was in great variation with relatively higher revenues.

Korea is a small country with extremely high population density. Industrialization of the nation resulted GNP per capita of over 2,000$ in 1986 with an inevitable by-product, high level of pollution in many areas. Forest land is now acknowledged as not only a wood production site but also an origin of much more important intangible values, water and clean air, soil conservation, and recreational and scenic values. Mostly devastated forest land from Korean War has been recovered under the strong afforestation drive from the government. The first Forest Development Plan was mostly reforestation phase and the second Forest Development Plan is foundation establishment phase. The third and later Plans are to enlarge economical forest and to maintain sustatined yield phase. Forestry administration as well as forest research certainly played a great role in successful accomplishment of two Forest Development Plans. For effective planning and accomplishment of the third Forest Development Plan close cooperation among policy makers, forest managers and research workers are mostly required.

The effectiveness of silica-based microgels prepared through the reaction of sulfuric acid and sodium silicate as a component of Compozil system has been evaluated . Silica based microgels with better performance in retention and drainage than a commercial colloidal silica sol have been successfully prepared. Silica gels with the highest charge density were obtained when product pH was controlled to 9. And highly charged silica-based microgels showed greater retention and freeness performance than a commerical product. In particular the difference in retention, turbidity , and freeness between these microgels and a commercial product was eminent at low addition rate. The effects of reaction conditions including reaction temperature, process water quality and feeing rate on product efficiency in improving retention and drainage were also investigated and discussed.
