최근 목재이용과 목공활동 등을 선호하는 사회적 분위기가 조성되고 있지만, 상대적으로 일반인이 목재문화를 향유할 수 있는 기회가 많지 않기 때문에 목재문화에 대한 인식과 기반이 부족한 상황이다. 본 연구에서는 일반인이 목재문화를 누릴 수 있는 확산전략 수립의 기초자료로써 목재문화에 대한 유형분류 및 사례분석을 수행하였다. 목재문화자원에 대한 개념을 정립하기 위하여 목재문화와 문화자원이 갖는 특수성을 분석하였다. 이를 통하여 목재문화자원은 보존·발굴·활용의 측면에서 목재 및 목재사용의 문화적 가치를 내포하고 있는 인류의 문화적 활동의 결과로 만들어진 산물로 정의하였다. 문화자원에 대하여 수행된 유형분류 사례를 분석하여 목재문화자원의 유형을 문화유산, 문화시설, 문화행사, 목조건축, 문화콘텐츠, 문화교육, 목재제품의 7가지 범주로 분류하였다. 또한 각 목재문화자원별 유형에 대한 사례를 발굴하여 제안하였다.

목재문화 활성화 전략을 수립하기 위한 기초연구로써 일반인의 목재문화에 대한 인식정도와 유형별 목재문화자원의 체험현황에 대한 설문조사를 진행하였다. 응답자의 31.4%가 목재문화자원에 대하여 궁궐, 사찰, 한옥, 문화재 등 문화유산의 이미지를 갖고 있는 것으로 조사되었다. 목재문화자원에 대한 이미지가 없다는 응답자 중에서 목재문화자원의 개념이 모호하기 때문이라는 응답이 40.2%이었으며, 목재문화자원 자체를 생각해본 적이 없다는 응답이 40.1%이었다. 7가지로 분류된 목재문화자원의 중요도는 문화유산, 목조건축, 문화시설, 문화행사, 목재제품, 문화교육, 문화콘텐츠의 순서로 나타났다. 목재문화자원을 체험하기 위한 정보의 필요성과 충분성에 대한 설문에서 응답자의 46.7%는 다양한 정보가 필요하다고 하였으며, 응답자의 64.8%는 충분한 정보가 제공되지 않는다고 하였다. 향후 1년 이내에 목재문화를 체험하고 싶은 의향은 대부분의 목재문화자원에서 과반 이상의 응답율을 나타냈으나, 실제로 7가지 목재문화자원에 참여하였던 빈도는 일상생활에서 사용되는 목재제품을 제외하면 20% 내외로 나타났다. 이러한 결과를 토대로 일반인이 목재문화자원을 체험할 수 있는 기회를 확대하고 보다 대중화하기 위해서 다양한 콘텐츠를 개발하고, 일반인에게 홍보할 수 있는 체계적인 전략수립이 요구된다.

This study was carried out to develop eco-friendly wood street lamp (EFWSL) by using wood resources stacked in the forests after tree tending operations which were mostly abandoned, but economical as renewable wood resources for developing the wood coated street lamps with the effects of cost reduction and their attractive appearances. This study has led to the development of key compact structures of street-lighting wood poles (shaft) using laminated timber. The core technique in this study is related with producing the more stable wood poles (shaft) with the hole inside than wood poles exposed under the natural environment through applicable process to protect the wood from bursting and splitting. We also comprehensively developed the method to conserve the timber durability of wood shaft and connect the wood shaft with groove, race way to be located in the groove, locking ring, current stabilizer connected to the groove and luminaire support arm, base and hand-hole which was partly used in combination with steel materials and wood. Also we increased the utilization of abandoned and stacked woods after thinning in the forests such as Pinus densiflora, Larix leptolepis, and Pinus koraiensis plantations by maximizing the value of these natural wood resources as main materials of eco-friendly street lightings with the effects of cost reduction and attractive appearances and also the expectation of advertising effects of street lightings developed in this study.

Wood and concrete show significantly different physical properties, and it need to be firstly understood for using wood-concrete composite. This study is performed for compensating this and effective hybridization of wood and concrete. This research in planned for wood-concrete composite after previous research which deals the shear performance with different anchorage length of steel rebar in wood. Yield mode and reference design value (Z) were derived using EYM (European Yield Model). And the yield mode changed before and after anchorage length of 10~15 mm - $I_s$ mode to IV mode. There was not increasing tendency of shear performance with increased anchorage length for over 20 mm of anchorage in concrete. And wood composite shows 65% and 93% on initial stiffness and yield load respectively compared with the wood-concrete composite. Wood-concrete composite showed brittle failure after yield point while wood-to-wood composite showed ductile failure.

Two experiments were conducted to investigate the feeding value of wood vinegar in weanling pigs. In Experiment 1, weanling pigs (n = 224; Landrace ${\times}$Yorkshire ${\times}$Duroc, 21${\pm}$3 d-old, initial BW 6.12${\pm}$0.10 kg) were assigned to four dietary treatments. Different levels of wood vinegar were added to the diets as dietary treatments (0, 0.1, 0.2 and 0.3%). Each treatment comprised 4 replicates with 14 piglets in each. Experimental feeding was conducted for 28 d in two phases (phase I, d 0 to 14 and phase II, d 15 to 28). Feeding of wood vinegar linearly (p<0.05) improved the phase I, phase II and overall ADG and increased (linear, p<0.05) the overall and phase II ADFI. Linear improvements in the apparent fecal digestibility of dry matter (p = 0.013), gross energy (p = 0.019) and crude protein (p = 0.033) were observed as the level of wood vinegar was increased in the diet of pigs. Experiment 2 was conducted to compare dietary wood vinegar with commonly used growth promoters, organic acid (mixture of 21% phosphoric acid, 3.25% propionic acid, 2.8% formic acid, 10% calcium formate and 5% calcium propionate) and antibiotic (aparamycin). A total of 288 weanling piglets (Landrace ${\times}$Yorkshire ${\times}$Duroc, 22${\pm}$2 d-old, initial BW 6.62${\pm}$0.31 kg) were assigned to four treatments with four replicates (18 piglets/pen) for 28 days and fed in 2 phases: phase I, d 0 to 14 and phase II, d 15 to 28. The dietary treatments were control (corn-soybean meal basal diet without antibiotics) and diets containing 0.2% antibiotic, 0.2% organic acid and 0.2% wood vinegar. Pigs fed antibiotic showed higher (p<0.001) ADG and better feed efficiency followed by pigs fed wood vinegar and organic acid diets while those fed the control diet had lowest ADG and poorest feed efficiency. The overall and phase I ADFI was highest (p<0.001) in pigs fed wood vinegar and lowest in pigs fed the control diet. Apparent fecal digestibility of dry matter, gross energy and crude protein was significantly higher (p<0.05) in pigs fed the antibiotic diet when compared with pigs fed the control but comparable among pigs fed antibiotic, organic acid and wood vinegar diets. Higher populations of Lactobacillus (p = 0.004) were noted in the ileum of pigs fed the wood vinegar diet, while the population of coliforms in the ileum and cecum was higher (p<0.001) in pigs fed the control diet when compared with pigs fed antibiotic, organic acid or wood vinegar diets. These results indicated that wood vinegar could improve the performance of weanling pigs by improving the nutrient digestibility and reducing harmful intestinal coliforms; moreover performance of pigs fed wood vinegar was superior to those fed organic acid.

Juvenile and transitional-juvenile wood samples from loblolly pine (Pinus taeda) were immersed in water to investigate longitudinal and tangential swelling properties. Increment cores from twenty-six loblolly pine trees were sampled at breast height (1.37 m). Earlywood rings 5 and 9 were separated from the core, extracted, oven-dried and immersed in water at room temperature. The variance in longitudinal swell was significant for ring 5 compared to ring 9 (p = 0.001). It was found that tangential swell might predict longitudinal swelling of juvenile wood at ring 9 but not at ring 5. Poor correlation in ring 5 suggests that swelling response in younger juvenile wood may differ. The swell response at ring 5 did not follow the shrinkage models discussed in the literature while ring 9 adhered to the expected curve.

In this study, the coating properties and surface performance of exotic cherry wood (Prunus serotina) were estimated, reviewing color difference, hardness and abrasion resistibility in order to evaluate probability as construction interior members such as wall and floor. The reduction effect of color difference was represented in the order of water soluble color stain, water soluble transparent stain, and non-coated lumber. However, the tendency of distinct difference according to wood grain pattern was not found. The wavy grain lumber showed better properties in hardness and resistance to abrasion than quarter grain. In conclusion, it was supposed that the application of wavy grain lumber in wall and floor as interior materials would be acceptable in practicality.

Understanding of the properties of woods is important in wood utilization. Until now, traditional wooden houses(Korean-style house, Buddhist temple, royal palaces) and furniture have been made of domestic woods with the experience of a craftsman rather than the scientific knowledge on woods. Because of concrete-based houses and imported wood products and furniture, even wood craftsmen decrease in number, too. This study was carried out to collect wood samples growing in Korea and to measure wood characteristics. Anatomical, physical and mechanical properties of 37 wood species were investigated.
