The rate of utilization of the oak cork (bark of Quercus variabilis Blume) ranges only 40-50%. Therefore, this study was carried out to investigate the chemical properties of the oak cork for increasing the utility. 1) The contents of alkali extractives, organic solvent extractives and ash in the oak cork are similar to those of other barks, but hot and cold water extractives and lignin contents are lower than those of the wood. The carbohydrate (cellulose and hemicellulose) content of the oak cork is similar to that of other barks. The suberin contents in the first and the second hark of the oak cork are 34.8 and 32.2% respectively, in the dry weight. 2) Inorganic component contents of the first bark are similar to those of the second. The pH of the first and the second bark are 3.9 and 4.2%. The caloric values of the first and second bark are 6,263 Kcal/㎏. and 5,828 Kcal/㎏, respectively, and these caloric values are higher than those of other harks. The sclerencymatous cell content of the first bark which is related to the quality of the oak cork is lower than that of second bark, the contents of the sclerenchymatous cell and lignin show the positive correlation. 3) In the dimension of the cross sectioned cork cell, the first bark is bigger than that of the second. The shape of the cork cell is globular shape in the early bark and discoid shape in the late bark. The cross and the radial section are the same shape, but the tangential section shows difference from the other section.

This study was carried out to investigate on the catalytic pyrolysis products of hardwood (Alnus hirsuta (Spach) Rupr. Quercus acutissima Carruters, Robinia pseudoacacia L., and Populus tomentaglandulosa T. Lee) and comparing the rate of catalytic pyrolysis from untreated wood (ordinary wood) with that of treated wood with catalizer (Ammonium phosphate, Ammonium sulfate, Ammonium chloride and Urea). The results were summerized as follows; 1) It is the Populus tomentiglandulosa T. Lee that the species has the most content of holocellulose and pentosan. And Populus tomentiglandulosa exhibited high yield of the distillate in pyrolysis products by Ammonium phosphate with catalizer. 2) The distillate of pyrolysis products is decreased in accordance with increasing catalytic concentration. And untreated wood (ordinary wood) with catalizer has the most distillate of pyrolysis products. 3) The yield of charcoal in pyrolysis products is increased in accordance with increasing catalytic concentration and lignin content of species. 4) The caloric values of charcoal in pyrolysis products is decreased with increasing catalytic concentration. And untreated wood (ordinary wood) with catalizer had the most caloric values, but the caloric values of charcoal did not show statistically significent difference at 5% levels in catalizer.

PURPOSE The outdoor camping market size is expected to hit a new high in 2021 as the popularity of outdoor activities surges due to the COVID-19 pandemic. The purpose of this study was to investigate the structural relationships among servicescape, perceived value, flow and behavioral intention, focusing on participants of international outdoor camping exhibition. METHODS Demographic analysis, confirmatory factor analysis, and structural equation modeling analysis were perfomed. RESULTS The findings suggest that (1) all servicescape factors (attractiveness, cleanliness, accessibility and responsiveness) have a positive effect on perceived value, (2) attractiveness, cleanliness and responsiveness are significant predictors of flow, (3) perceived value affects both flow and behavioral intention, and (4) flow also significantly impacts behavioral intention. CONCLUSIONS These findings highlight that high quality servicescape can result in enhancing a positive perceived value and flow, and in turn leading to behavioral intention of consumers. Hence, it is recommended for practitioners and staff of the exhibitions to considering the strategies for improving servicescape factors in order to achieve their goal. [목적] 코로나19 시대를 맞아 아웃도어캠핑이 안전하고 독립적인 여가소비 공간으로 전환되며 대중의 관심을 사로잡고있다. 아웃도어캠핑산업 규모의 급격한 증가와 함께 아웃도어캠핑전시회에 대한 수요도 늘어나고 있다. 이러한 시점에서 이 연구는 아웃도어캠핑전시회의 서비스스케이프와 참관객의 지각된 가치, 플로우, 행동의도 간 구조적 영향 관계를살펴보았다. [방법] 2021년 10월, 경기도 고양시 킨텍스 종합전시장에서 개최된 고카프(GOCAF) 아웃도어캠핑전시회 참관객 400 명을 대상으로 설문조사를 진행하고 유효표본 389부를 도출하였다. SPSS 23.0과 AMOS 23.0을 활용하여 각각 빈도분석과 확인적 요인분석 외 상관관계분석, 구조방정식모형분석을 실시하였다. [결과] 분석에 따른 연구의 결과는 다음과 같다. 첫째, 매력성, 청결성, 접근편의성, 종사원 대응성 등 모든 서비스스케이프 구성요인은 참관객의 지각된 가치에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 둘째, 서비스스케이프 구성요인 중 매력성, 청결성, 종사원 대응성은 참관객의 플로우에 유의한 정(+)의 영향을 미치는 것으로 밝혀졌다. 셋째, 지각된 가치는 플로우에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 넷째, 지각된 가치와 플로우는 행동의도에 각각유의한 정(+)의 영향을 미치는 것으로 확인되었다. [결론] 이 연구는 전시회의 서비스스케이프가 참관객의 지각된 가치와 플로우에 긍정적인 영향을 미치고, 지각된 가치와 플로우는 다시 참관객의 행동의도에 유의한 영향을 미치는 것을 규명하였다. 따라서 지속적인 캠핑산업 발전과 전시회 참관객의 증대를 위해 아웃도어캠핑전시회의 물리적 공간에 대한 전략적 개선과 함께 서비스를 제공하는 인적요인의 체계적인 품질관리가 요구된다.
