The study investigates the impact of the environmental protection tax, along with other factors such as attitude, subjective norm, environmental concern, and the availability of substitutes on the use of plastic bags in Vietnam. To achieve this objective, a questionnaire was prepared for data collection. The questionnaire employed a 5-point Likert scale with "completely disagree" at 1 and "completely agree" at 5. A total of 327 questionnaires were returned. However, only 291 valid responders were used in the analysis. The Cronbach's Alpha and the exploratory factor analysis were applied to test the scale reliability and discover the structure of the scales. Afterwards, we conducted the confirmatory factor analysis and the structural equation modeling to analyze collected data. The study shows that attitude is an important factor influencing the plastic bag use of consumers. Other factors that also lead to a decline in plastic bags are subjective norm and environmental concern. Meanwhile, the availability of substitutes does not affect consumers' green behavior. Moreover, the major findings of the research suggest the relationship between the environmental protection tax and the use of plastic bags is not statistically significant. In other words, tax policy may fail to change the habit of using plastic bags in Vietnam.

Today many people are greatly interested in the environment. Especially increasing affluent of food causes a great amount of food waste. To handle this effectively, we now have a lot of problems of disposing garbage all over the world. In Korea, in order to reduce this garbage, we should use a standard plastic garbage bag in which we have to throw away our garbage. So it has an effect on significantly reducing the waste amount every year. Now, there are a lot of cases that residents again use a standard plastic garbage bag. The purpose of this study is to propose algorithm preventing the re-cycling of a standard plastic garbage bag.

To address threats to the natural environment, the government in Pakistan has banned the use of plastic bags for shopping. The concept of governmentality presented by Michel Foucault explores the techniques of governance and defines law not just as the manifestation of sovereign power but also as a technique of governance involving a range of organized practices designed to shape mentalities to achieve certain desired ends in subjects which claim to be for the welfare of the population. The present study explores the perceptions of the consumers regarding the rationality of the government behind the ban and also highlights the effectiveness of the use of law as a technique of governance. A qualitative approach was used by conducting fifteen interviews with young consumers selected through convenience sampling. The findings suggest that the rationality of the government behind the ban was received well by the consumers and the ban was viewed as a positive and pro-environmental step. The use of law as a technique of governance also proved to be effective in the said case because the people did not perceive the law as coercive despite the radical change it brought to their shopping practices. The present study contributes to the development of the theoretical understanding of governmentality and its sub-concept of the use of law as a technique of governance.

Poria cocos is an edible and pharmaceutical mushroom with a long history of medicinal use in Korea. For the last 30 years, the domestic cultivated supply of Poria cocos has been unable to meet consumer demand, so Poria cocos is collected in mountainous areas and also imported from China. Thus, to increase the supply of Poria cocos, many artificial cultivation methods have been studied. In this study, Poria cocos is cultivated under different environmental conditions using plastic bags and the results compared. When cultivating Poria cocos at different temperatures (20, 25, 30 and $35^{\circ}C$) and using different numbers of plastic bag layers (1, 2), the most efficient cultivation conditions were a temperature of $25-30^{\circ}C$ and 2 plastic bag layers. The fastest growth was at $25-30^{\circ}C$, and the Poria cocos exhibited no weight change when cultivated using layers of plastic bags (1, 2).

Since the use of plastics in various goods such as film, containers, and packaging has been increasing in Korea, the generation of plastic waste is increasing. Plastic wastes are managed by waste charge system, Extended Producer Responsibility (EPR) system and voluntary agreement of plastic waste collection-recycling system. Recently, the management of plastic waste is becoming a social issues due to the refusal of the collection of plastic waste including waste plastic bag and waste vinyl. The ministry of environment in korea was set up the comprehensive plan for recycling waste management in accordance with the circulation cycle of manufacturing and production - distribution and consumption - separate and discharge - collection and sorting - recycling. In this study, the improvements for management of plastic waste were suggested with the review of domestic waste plastics management and the comprehensive plan by the ministry of environment.

Bulging of the lower eyelid & tear trough groove is regarded as a sign of aging. In the past, the surgical excision of the fat pad has been the mainstray of the management of lower palpebral bag in cosmetic blepharoplasty, Recently, fat pad sliding method has been introduced to make more attractive lower eyelids. We used the fat pad for covering the hollowness of the lower eye lid. And we use redundant fat pad for filling & augmentation of the lower eye lid by reflexion. Redraping of the orbicularis arc, with its accompanying midfacial fat repositioning, anatomically restores the cheek and lower lid to make more youthful contour. By redraping and fixing the orbicularis arc on the medial surface of the orbital rim, it becomes a more attractive midface and may prevent of ectropion. From August, 2002 to July, 2004 in correction of lower palpebral bulge & tear trough groove, these two technique were performed in 42 consecutive individuals (84 lower eyelid) for two-year period. Follow up ranged from 3 to 15 months. (an average of 9 months) Palpebral bulge & tear trough groove were corrected and obtained a youthful midface. Complication was rare. The advantages of these techniques are that: prevent in of secondary palpebral bulge and irregularity of lower eyelid by using of reflexed fat fad; prevent in of ectropion. Thus an attractive midface is obtained by redraping of orbicularis arc.

The enforcement of volume-rate disposal system which has been resulted in reducing the household waste and increasing the amount of recycled contents is showing positive effects that are generating social and economic benefits, However due to the lack of user's perception about how to separate and dispose of recycling wastes, some problems are constantly raised, like food waste is disposed in the standard volume-rate garbage bag. By rearranging visual information printed on standard plastic garbage bags (SPGB), this study attempted to find ways to deliver the information regarding how to use them properly. In order to achieve this, from the perspective of visual information design, the study examined the cases of visual information printed on nine SPGB from domestic and overseas. Among these, this study conducted a survey on user's awareness of visual information printed on SPGB in three districts of Seoul, Korea. As a result, user-preferred items were identified. Based on the result, this study selected information to be printed on SPGB, established the hierarchical order of the selected information, and proposed a guideline for using SPGB with informative graphics; therefore, the effectiveness of information delivery was improved. In addition, this study also examined the external validity of the guideline by comparing a survey on user's awareness.

Purpose - While sustainability is based on the argument that the world's resources are finite and their demand will ultimately surpass supply, entrepreneurship on the other hand argues that there are inherent opportunities to address this through conserving, recycling, switching to more renewable resources and making effective use of available finite resources. Research design, data, and methodology - In response to the lack of scientific information on the outcomes of entrepreneurship in rural Nigeria, this paper surveys the benefits (social, economic and environmental) of women engagement in waste plastic bags recycling in Adamawa State of Nigeria. A descriptive research design was adopted and data was collected from 26 respondents with the use of a semi-structured questionnaire, which was analyzed using descriptive statistics and presented in frequency tables. Results - Results indicated that 21 women have gained employment, who would have remained unemployed; 80.8% of who make profits below 10000 Naira per month and collectively, they recycle 179.3kg of waste polythene bag per month. Conclusions - It was recommended that the women should be further their education; adequate records of costs and sales should be kept; and savings should be encouraged among them.

This study is to estimate that food waste bags with biodegradable plastic are really decomposed by microorganism in composting with food waste and to examinate how biodegradable plastic affects composting. 6 kinds of 30%, 4 kinds of 100% and 2 kinds of none biodegradable plastics were used in d1is study. In 30% biodegradable plastics the highest Degradation rare is 6% in meso-condition and 10% in thermal-condition. Srain at auto break decreased to 150% in meso-condition and 120% in thermal-condition. Stress at max load were also reduced to $180kgf/cm^2$ in mesocondition and $200kgf/cm^2$ in thermal-condition. Usually, LLDPE decreased larger than HDPE in physical characreristics but HDPE is higher in degradation rate. 1n stain at auto break and stress ar max load 100% biodegradable plastic declined to 230% and to $380kgf/cm^2$ in meso-condition and to 440% and to $400/cm^2$ in thermal-condition respectively. 100% biodegradable plastics showed higher biodegradation and decomposition then 30%. They appeared clearly through SEM observation. As a result, it was not appropriate to use 30% biodegradable plastics as food waste bag because they were not decomposed perfectly. It is possible to use 100% biodegradable plastic as it but cost is too high. So development of technique is needed.
