According as gradually increasing the demand for Eco-friendly products it has been progressed fairly development at a field of printing and printing inks. The Inks are used by soy oil beginning of ink industry for preventing environment. Now it is possible to make Eco-friendly inks with vegetable ester. So it is not necessary to use petroleum-based solvents for preventing environment. But There is some problems if using vegetable ester to inks. Vegetable ester has high solubility, it causes misting and low viscosity of the Inks. So resin is required high performance. Thus, in this paper, I studied about the properties variation of the Varnish and inks According to using the phenolic modified rosin ester and Soy oil Methyl esters. The compared in order of average molecular weight by the GPC method, rheological properties were found by rotational rheometer, and emulsion behavior were compared by high speed emulsification tester.

In the past, there were several researchers investigating waves generated by a small boat. Wave generated by a ship can be divided into two distinct systems of waves, such as transverse and diverging waves. It is necessary to understand the behavior of a ship in waves generated by a small boat near port in the view point of ship safety. In this study, the motion of moored floater in waves generated by a small boat near port is investigated. The model test is performed in waves in a square tank in Changwon National University (CWNU). IMU and optical-based system which uses the technique of recording and capturing attitude with respect time are used for measuring 6DOF motion of the moored floater. In addition, tension gauges are used to measure the tension of mooring lines. The effect of waves generated by a small boat on motion of the moored floater near port is investigated through performing the model test in various wave directions of virtually but reasonably assumed wave scenarios.

Using non-biodegradable polymers is a severe environmental problem as they are not recyclable and generate a large amount of waste. Biopolymers, such as starch-based composites, have been considered one of the most promising replacement materials. These eco-friendly materials have the advantage of being low-cost, biodegradable, and obtained from renewable sources. However, as starch tends to be brittle and hydrophilic, it can make these materials unusable when exposed to water and limit its processability for further applications. In this work, a biobased modified starch was grafted using two bioderived materials, lauryl methacrylate (LMA) and tetrahydrofurfuryl methacrylate (THFMA), by radical polymerization. A polylactic acid (PLA) composite based on the modified starch (m-St) was fabricated to enhance its toughness. These samples were characterized by Fourier transform infrared, ¹H NMR and ¹³C NMR analysis, optical and scanning electron microscopy. The starch was successfully grafted, thus improving the compatibility with the PLA matrix. The mechanical properties of these films were also studied. Results from mechanical tests showed a slight enhancement of the mechanical performance of these composites when m-St was added to the PLA matrix. Such behavior is related to the improved dispersion of m-St 1:2 on PLA, confirmed by SEM images showing enhanced compatibility between modified starch and PLA matrix. This indicated excellent properties of the produced composite film for further eco-friendly applications.

The purposes of this study were 1) to classify adult consumers according to their desired clothing benefits on natural-dyed clothes, 2) to identify the differences of life-style among the classified groups, and 3) to determine the interest in Korean traditional culture, interest in dyeing, and demographics among the groups. The survey subjects were 283 adults. The data were analyzed utilizing factor analysis, cluster analysis, $x^2$-test, one-way ANOVA, Duncan test and multiple regression analysis. Based on the 6 dimensions of clothing benefits that were identified by factor analysis, adult consumers were classified into three clusters: eco-friendly oriented group showing the highest scores in environment conservation and comfort in clothing benefits, individuality-oriented group showing the highest scores in individuality and quality, and indifference group showing lower scores in all of the desired clothing benefits. The eco-friendly group showed the highest scores in attitude toward Korean traditional culture, and tended to have the most interest in natural and traditional methods of dyeing. The group members appeared to have passive life-styles, be older and married, and have a higher income than the other groups. The more positive attitude they had in Korean traditional culture, the higher was the purchase intention shown in the eco-friendly group. The individuality-oriented group showed active life-styles. This group tended to be younger than the other group. The more affirmative attitude in Korean traditional culture and the greater interest in the natural dyeing, the higher was the consumers' purchase intention of natural dyeing apparels. The indifference group tended to be younger, unmarried, and have a lower income. This group was not interested in natural dyeing apparels. The study findings demonstrated that consumers with different clothing benefits sought have different buying patterns on natural dyeing apparels. Finally the marketing implications are discussed.

Consumer interest in eco-friendly fashion products has been consistent. While most relevant research emphasizes individual morals and environmental concern as the most crucial determinants to eco-friendly consumption behavior, more recent studies point out that in so doing there has been somewhat a neglectance on the importance of fundamental marketing strategies. More specifically, the crucial role of interior colors in fashion retail stores has been managerially considered something certain yet no empirical results have been found to support such a strong managerial assumption. For instance, colors such as green, blue, and brown are believed to represent natural images and are more appropriate to the eco-friendly marketing and the relevant research has been lacking. Therefore, this study attempts to explore the effect of in-store interior design colors (green versus non-green) on consumer perception of green store images. A total of 382 respondents were gathered for an online survey using differing store images as the stimulus and used for testing hypotheses. In the results, respondents exposed to store images using green interior colors reported a higher evaluation of green store image of the store. The effect is found to be significantly moderated by respondent's environmental concern: to explain, respondents of high environmental concern are less influenced by green color interiors when they evaluate the brand's eco-friendly image. In sum, the positive influence of green interior colors on green store image is found statistically significant, with its stronger effect for consumers of low concern. Managerial and academic discussions are provided.

A series of laboratory experiments has been performed in order to investigate the behavior of water-air two-phase flow in a horizontal pipe. A conductivity meter has been applied to detect the irregular alternation of air at the specific points in flows. The experimental condition has been established according to the water and air flowrates. Passing time, which is the time length for a measuring probe to pass through the entire length of a specific bubble, has been defined to evaluate the size of bubbles in the flow. Passing length, which can be considered as the equivalent value to bubble size and determined from the product of passing time and cross-sectional averaged velocity, and its corresponding occurrence frequency have been analyzed to classify the air flow patterns according to the condition of air and water fluxes. From the result, the dependancy of flow patterns on the variation of air-water flux ratio has been investigated and the existence of thresholds also checked for classifying the behavior of air in the flow.

This study has verified the consumer effectiveness market influence and relationship with cosmetic purchasing behavior through a covariance model. A female consumer in her 20s or older who had purchased eco cosmetics within the last six months and 300 copies were used for final analysis through panels of online professional research institutes from May 17 to May 30, 2020. As a result of the analysis, functional value, social value, and green consumption value were derived from the consumption value of eco cosmetics. Social value and green consumption value have been shown to have significant impact on consumer effectiveness and market influence but functional value relationships have not been identified. In addition, consumer effectiveness and market influence were found to promote eco cosmetics purchase behavior. Through this study we have identified the importance of perceived environmental issues (consumer effectiveness and market influence) in purchasing eco cosmetics and hope that they will be used as useful data for developing eco products and establishing marketing strategies based on understanding of consumers.

Consumers' growing interest in the environment has recently led them to recognize the importance of their dietary life and sustainable consumption. Thus, there is an increasing necessity to identify consumers' response on the relationship between the consumption of functional food and their interest in helping environment. This research was conducted to analyze consumers' behaviors as related to Spirulina, an eco-friendly functional food brand, by subdividing markets according to consumers' food lifestyle. The results showed that consumers were categorized into 3 types (high involvement in diet, pursuit of safety in diet, and pursuit of convenience in diet), and there was a significant difference in the consumption behaviors of the functional food according to the 3 types. Their positive attitude towards functional food and interest in the environment led to changes of their actual purchasing behavior by increased purchase of Spirulina. Also, consumers who displayed high environmental involvement showed a more favorable attitude towards functional food. Therefore, to expand the market of eco-friendly functional food, it is necessary to subdivide the market and target the consumers who are highly involved with protecting the environment, and to execute marketing strategies for eco-friendly products, in order to increase the consumers' awareness about eco-friendly functional food.
