Unmanned aerial vehicles (UAVs) are a new and yet constantly developing part of forest inventory studies and vegetation-monitoring fields. Covering large areas, their extensive usage has saved time and money for researchers and conservationists to survey vegetation for various data analyses. Post-processing imaging software has improved the effectiveness of UAVs further by providing 3D models for accurate visualization of the data. We focus on determining the coniferous tree coverage to show the current advantages and disadvantages of the orthorectified 2D and 3D models obtained from the image photogrammetry software, Pix4Dmapper Pro-Non-Commercial. We also examine the methodology used for mapping the study site, additionally investigating the spread of coniferous trees. The collected images were transformed into 2D black and white binary pixel images to calculate the coverage area of coniferous trees in the study site using MATLAB. The research was able to conclude that the 3D model was effective in perceiving the tree composition in the designated site, while the orthorectified 2D map is appropriate for the clear differentiation of coniferous and deciduous trees. In its conclusion, the paper will also be able to show how UAVs could be improved for future usability.

In recent years, the municipal wastes recognized resources. This study was performed to survey the changes of main components of the pretreated(chemical, physical) lignocellulosic biomass. The result can be summerized as follows; In pulp fiber composition, newsprint and corrugating container were mainly consist of softwood fiber(tracheid). But computer print out and magazine had a large amount of hardwood fiber(wood fiber). And, carbohydrate content in the various lignocellulosic biomass increases as the following orders : Magazine < Newsprint < Corrugating container < Computer print out. In the chemical pretreatments for the delignification, sodium hypochlorite pretreatment was more effective than sodium hydroxide. By washing, ash content of lignocellulosic biomass was decreased. Physical pretreatments were less effective than chemical pretreatment for the delignification. On the other hand, in physical pretreatments, ash content of lignocellulosic biomass was the same tendency as in the chemical pretreatments.

This study examines social identity and self-identity as the antecedents of the theory of planned behavior (TPB) model in predicting purchase intention of certified coffee, whereas perceived trustworthiness (PT) is evaluated whether it directly affects intention and/or indirectly through attitude. In addition, ethics and luxury are investigated as the salient beliefs affecting attitude formation in this regard. A face-to-face survey was conducted with 727 coffee consumers in Thailand. Confirmatory factor analysis is applied to assess the adequacy of the model, followed by structural equation modeling to evaluate the hypotheses proposed for the relationships between constructs in an extended TPB model. The results confirm that self-identity is the most influential antecedent on attitude when compared to social identity, and attitude, in turn, is the strongest determinant in predicting purchase intention. PT has a direct positive effect on purchase intention, meanwhile, ethical, luxury beliefs, and PT are confirmed to portrait the attitude formation. As such the marketing campaigns can address manipulating consumers' beliefs on both ethical and luxury aspects as well as PT, along with consumers' social identity and self-identity to fortify a positive attitude toward certified coffee. Then the actual purchase behavior can be foreseen based on empirical evidence.

During a survey of fungal diversity associated with insects, mud, soil, and freshwater niches in different areas in Korea, nine interesting fungal strains were isolated. Based on their morphological characteristics and molecular phylogeny analyses, using a combined data set of b-tubulin (BenA), calmodulin (CaM), and second largest subunit of RNA polymerase (RPB2) sequences, the strains CNUFC AM-44, CNUFC JCW3-4, CNUFC S708, CNUFC WT202, CNUFC AS1-29, CNUFC JCW3-5, CNUFC JDP37, and CNUFC JDP62 were identified as Aspergillus alabamensis, A. floridensis, A. subversicolor, Penicillium flavigenum, P. laevigatum, P. lenticrescens, Talaromyces adpressus, and T. beijingensis, respectively. The strain CNUFC JT1301 belongs to series Westlingiorum in section Citrina and is phylogenetically related to P. manginii. However, slow growth when cultivated on CYA, MEA, CREA is observed and the property can be used to easily distinguish the new species from these species. Additionally, P. manginii is known to produce sclerotia, while CNUFC JT1301 strain does not. Herein, the new fungal species is proposed as P. aquadulcis sp. nov. Eight species, A. alabamensis, A. floridensis, A. subversicolor, P. flavigenum, P. laevigatum, P. lenticrescens, T. adpressus, and T. beijingensis, have not been previously reported in Korea. The present study expands the known distribution of fungal species belonging to the families Aspergillaceae and Trichocomaceae in Korea.

본 연구에서는 일반 시민을 대상으로 유기농업과 친환경 농산물에 대한 인식 및 구매행태를 조사하고, 유기농업에 대한 인식이 친환경 농산물의 소비와 가격 저항성에 영향을 미치는지, 또한 향후 유기농업 활성화를 위한 조건이 될 수 있는지에 대해서 도출하고자 하였다. 따라서 본 연구에서 설정된 연구 가설은 다음과 같다. 첫째, 유기농업의 환경성/공익성 인식은 친환경 농산물 소비에 영향을 미칠 것이다. 둘째, 유기농업의 환경성/공익성 인식은 유기농업 활성화에 영향을 미칠 것이다. 마지막으로, 친환경 농산물 소비 경험은 유기농업 활성화에 영향을 미칠 것이다. 이를 검증하기 위해 유기농업의 환경적·공익적 요인을 도출하여 전국 성인남녀 1,500명을 대상으로 인터넷 조사를 실시하였으며, 도출된 결과를 토대로 로지스틱 회귀분석 등 통계분석을 실시하였다. 분석 결과 유기농업에 대한 환경적·공익적 인식이 친환경 농산물 소비까지로 이어지는 요인이 아닌 것으로 나타났으나, 환경적·공익적 인식이 높은 경우 친환경 농산물 소비에 가장 큰 제약 원인인 가격에 대한 저항성이 낮은 것으로 확인되었다. 또한 환경적·공익적 인식이 강할수록 유기농업의 확대에 대한 지지와 친환경 농산물 구매의향에 긍정적인 영향을 미치는 것으로 나타났다. 본 연구의 결과는 유기농업에 대한 소비자 인식과 태도를 확인함으로써 향후 친환경 농산물 소비 및 유기농업 활성화 대책 마련의 기초 자료로서 활용될 것으로 기대된다.
