The diffusion strategies of wood culture were established using the analytic hierarchy process, to prepare a diffusion plan of wood culture and wood utilization in response to climate change due to global warming. 'Standardization of wood culture', 'Valuation of wood culture', and 'Habituation of wood culture' were set as three major implementation strategies and priorities were evaluated. As a result, it was analyzed in the following order: 'Development of systematic education programs for each age group for rational and efficient use of eco-friendly wood materials and development of wood education standard guidelines linked to the curriculum', 'Preparation of scientific basis data on human compatibility and eco-friendliness of wood to ensure the reliability of wood and wood products', and 'Establishment of monitoring and improvement plan through the designation as a model school'. Through this, it was determined that an educational environment, changes in public attitudes through publicity, and expanding opportunities to use wood and wood products were necessary for wood culture diffusion. The results of this study can be used as basic data to derive the diffusion strategies of wood culture and establish a roadmap and policy implementation strategy to revitalize wood culture.

The purpose of this research lies in analyzing the corelation between the eco-friendly management activities of a cosmetic company and customers' decision making in terms of purchase. In this research, 355 copies of questionaire from general customers were analyzed using the statistic package program of SPSS v.18.0. Based on the research analysis, the attributes of eco-friendly management activities can be categorized into three factors such as 'energy saving', 'contribution to communities', and 'environment-oriented services' and have the statistically meaningful positive influence on the three factors of customers' decision making; 'purchasing intention', 'assessment of purchase', and 'repurchase'. This research shows that the eco-friendly management activities of a cosmetic company is an important factor for its successful marketing strategy. This research has a significance in that it has studied the eco-friendly management activities of a cosmetic company through stereotyping. We can expect successful marketing effect if a cosmetic company uses eco-friendly products, information, and services in its eco-friendly marketing.

A various methodologies like eco product design, recycling, remanufacturing have been proposed for the increase of resource recirculation and energy saving worldwide. Uni-materialization in this paper, one of measures is presented. Uni-materialization is defined as the unification or simplification of material that is easy resource recycling and reduce waste generation at source during product design, manufacturing, delivery, use and disposal. This study developed calculates the qualitative and quantitative of assessment index for evaluating target products applicable uni-materialization. There are 9 assessment articles considered economic performance, technological property and environmental property and a study on target product applied assessment indexes. As a result it is possible for 3 target products to apply uni-materialization product except for a window blind, and the concrete concept of uni-materialization for improving objectivity of assessment index and the consideration of industrial distinct character are needed.

In the manufacture of corrugated box, the fibrous raw materials are mainly consisted of recycled papers, such as KOCC(Korean Old Corrugated Container), kraft sack, and AOCC(American Old Corrugated Container). Among these recycled waste paper, the proportion of KOCC is relatively higher than others in fibrous raw materials. Generally, KOCC shows some poor fiber properties and contains hazardous heavy metal sources. Therefore, it is to evaluate the property of recycled paper sources for eco-friendly corrugated box manufacture. In this study, the physical and mechanical properties of 3 kinds of recycled fibers and their mixed stocks were analyzed. The environmental assessment was also evaluated by analyzing the 4 representative heavy metal contents and evaporation residues in waste papers. As the results, KOCC showed the poorest fiber qualities and had the highest heavy metal contents and evaporation residues among the recycled fibers. Finally, the mechanical strength properties were increased by decreasing KOCC proportion of mixed stock conditions. In addition, the heavy metal contents and evaporation residues were also decreased by increasing recycled AOCC and kraft sack proportion.

BACKGROUND: The residual analysis of polar pesticides has remained a challenge. It is even more difficult to simultaneously analyze multiple polar pesticides. Diquat, paraquat, and chlormequat are typical examples of highly polar pesticides. The existing methods for the analysis of diquat, paraquat and chlormequat are complex and time consuming. Therefore, a simple, quick and effective method was developed in the represent study for simultaneous analysis of diquat, paraquat and chlormequat in animal products, meat and fat using UPLC-MS/MS. METHODS AND RESULTS: Sample extraction was carried out using acidified acetonitrile and water and re- extracted with acidified acetonitrile and combine the extracts followed by centrifugation. The extract was then cleaned up with a HLB cartridge after reconstitution with acidic acetonitrile and water. The method was validated in quintuplicate at three different concentrations. The limits of detection (LOD) and quantification (LOQ) were 0.0015 and 0.005 mg/L, respectively. Matrix suppression effect was observed for all of the analytes. A seven point matrix matched calibration curve was constructed for each of the compound resulted excellent linearity with determination coefficients (R2) ≥ 0.991. Accuracy and precision of the method was calculated from the recovery and repeatability and ranged from 62.4 to 119.7% with relative standard deviation less than 18.8%. CONCLUSION: The recovery and repeatability of the developed method were in the acceptable range according to the Codex Alimentarius guideline. The developed method can be applied for the routine monitoring of diquat, paraquat, and chlormequat in animal products, meat and fat.

Plasticizers are chemical additives added to polymers to have a desirable effect on mechanical properties such as processability and ductility. In this paper, we explore the use and market of eco-friendly plasticizers that can replace phthalate-based plasticizers that have been traditionally used in the plastics market. Bio plasticizers are derived primarily from biomass sources, including agricultural products, by-products and wastes. Regardless of the source of biomass, an ideal eco-friendly plasticizer should be non-toxic, have high resistance to volatilization, extraction, and migration, have good compatibility and compatibility, and be economical. The global bio plasticizer market is expected to reach USD 2.1 billion by 2030 from USD 1.3 billion in 2020, growing at a CAGR of 5.31% from 2021 to 2030.
