The purpose of this thesis is to suggest a Practical Plan for ethical consumption by reviewing the category of Vegan Fashion and investigating its Social Value of vegan fashion. This will be achieved through investigating the papers and official home pages of 13 selected Vegan Fashion brands. It was found that in terms of use of materials such as leather, fur and organic fibers the brands can be divided into three sections: fur-free, cruelty-free and perfect vegan. A Practical Plan is suggested based on the aspects of production, consumption, distribution and education. Firstly, the provider should be required to understand vegan materials deeply, it is also desirable for them to get vegan certifications. Secondly, the seller should also understand about vegan materials, and be able to explain this to consumers. The education from the seller is vital and the meaning of logos and associated contents used by the label should be clearly explained to consumers. Thirdly, the association of consumers, and fashion brands should cooperate to enhance the level of general understanding in society further, this should influence new laws, that address ethical issues regarding the use of fur in fashion. Environmental problem of the future might be reduced if the stakeholders in Vegan Fashion are cooperatively and actively trying to educate the general population and make Vegan Fashion popular and ethical consumption popular.

The study aims to understand the impact the consumption value changed by COVID-19 has on the purchasing behavior of industry foodservices dietitians and to provide baseline data in setting the marketing strategies for the food materials distribution companies in the future. The main survey was conducted for eight days from May 13th to 20th 2021 and 260 copies were collected and analyzed. Through the results of the study, the following conclusion elicited. First, consumption values that impact purchasing behaviors of industry foodservices dietitians are functional value and situational value. Second, for dietitians working at directly managed foodservice establishments, the higher the functional value of the food materials is, the higher the purchasing behavior. But such correlation was not found in the case of dietitians at consignment establishments. Third, compared to before and after COVID-19, the importance of functional value of food materials decreased, while the importance of situational value increased. Therefore, it is assumed that establishing marketing strategies differentiated by direct and consignment management will contribute to the energetic sales of the food material companies in the era of post COVID-19.

Earth friendly system is applied widely to industries for maintaining development. The declaration of earth friendly characteristic which is an indication of the total amount of energy in evaluation of earth friendly material is not easy to apply to building materials Therefore, Accurate standards about earth friendly materials are necessary. Earth friendly building materials should be considered in the fields of energy and resource consumption, changes in urban climate and resident health, etc. Among these fields, energy and resource consumption has released toxic pollutants into the air, caused indoor moisture problems and exhausted resources continuously. Especially, moisture problem is an indicator of main factors of earth friendly characteristic. Timber, Soil. Cement Mortar and Charcoal are used to examine the sustainable properties of materials of moisture control. The result shows that wood, charcoal and soil is vivid in changes of moisture absorption and discharge in comparison with that of cement mortar.

This study aimed to analyze preferences depending on consumption value in relation to fashion jewelry design, colors, and materials. For this, 156 female consumers participated in it as subjects, and for a research tool of consumption value, VALS (Values and Life Style) technique was employed to make an empirical analysis by dividing it into three types such as principle-oriented value, status-oriented value and behavior-oriented value. Research findings indicate that above all, there are differences in preferences depending on characteristics of fashion jewelry design depending on consumption value. It was found that there are differences in preferences depending on numbers of setting of fashion jewelry depending on consumption value, but it was found that there are no differences in preferences depending on jewelry materials. In addition, it was observed that for color characteristics of fashion jewelry, there are differences in preferences depending on consumption value. There are differences in preferences for fashion jewelry depending on consumption value, which indicates that preferences for products change depending on consumers' consumption value rather than use value. And it can be an explanation for this reason. Therefore, it is necessary to work out a more efficient strategy through a process of setting up a target according to consumption value.

This study was conducted to evaluate changes in food consumption during the 1950's on the basis of articles that reflected national policy and changes in society during that time period. Many factors are involved in the development and changes in food consumption culture, and these factors can affect each other. As a result, the process involved in the development of food consumption culture acts as a living system. This study evaluated the food consumption culture during the 1950's because this period was subjected to obvious influences that may explain the modern food consumption market logic and commercialism. Changes in the national food consumption are dependent on natural changes such as income enlargement or cultural exchange with a foreign country. Accordingly, food consumption during the 1950's was influenced by changes in economical, social, and political needs. In addition, the influx of surplus agricultural products from the United States had an adverse effect on local agriculture and resulted in an increased external dependence on food during the 1950s. Moreover, the import of raw materials and simple manufacturing techniques led to the development of an industrial food processing industry that enabled accelerated mass production of food at a low-price. Furthermore, the importation of surplus agricultural products from the United States that were used as the raw materials for foods that had traditionally been produced domestically led to an increased burden and qualitative decline in the local food-service industry. Taken together, the results of this study indicate that during the 1950's fresh food began to be replaced with processed foods in Korea.

The objective of this study was to investigate the metabolic energy consumption rate of the psychophysical Maximum Acceptable Weight of Loads (MAWLs) for different manual materials handling tasks. Lifting activities with four different lifting frequencies (2, 5, 8, 11 lifts/min) for a lifting range (from floor to 76cm height) were studied. The oxygen consumption rate and heart rate were measured or recorded while subjects were lifting their MAWLs. It was found that the relationship between MAWL and frequency can be described best by the exponential function with the R-sq value 0.9865 for this study. Psychophysical MAWL decreased from 22.38 to 7.48 kg, while the oxygen consumption rate with the MAWL increased from 717.8 to $1114.7m{\ell}-O_2/min$ as the frequency increased from 2 to 11 lifts/min. Heart rate also increased from 104.5 to 120.7 bpm. The ratio of oxygen consumption for the MAWL to the Physical Work Capacity (PWC) ranged from 28 to 43%. The MAWLs were greater than or equal to the Maximum Permissible Limits (MPLs) when the frequencies were higher than 8 lifts/min. It seems that the MAWLs by psychophysical approach when the frequencies were higher than 8 lifts/min tend to be overestimated from the viewpoint of the physiological criterion of the oxygen consumption rates. From these findings it is suggested that the NIOSH Guideline should not be directly applied to Korean without reasonable modifications.

The role of KOH in the one-stage KOH-activation of rice straws was studied using FTIR, XPS, TGA, and DTG techniques. It was found that at the impregnation, KOH extracts to some extent the lignin component from rice straw and reacts with hydroxyl groups. On heat-treatment, the impregnated KOH facilitates intermolecular condensation reaction on one hand but retards the thermal degradation of cellulose molecules on the other hand. The oxygen-containing surface functional groups newly created by oxidation of KOH may facilitate the bulk, not controlled, consumption of carbon atoms so that the effective porosities may not be able to be developed by the one-stage activation process.

The increase of greenhouse gas emission and decrease of fossil fuel are being caused by the indiscreet consumption of energy by people. Recently, green policy has been globally implemented to reduce energy consumption. This paper studied the research to reduce the energy consumption in buildings, by using the heat storage properties of PCM. PCM has to prevent leakage from the liquid state. Therefore, we prepared form stable PCM, by using the vacuum impregnation method. Three kinds of organic PCMs were impregnated into the structure of porous material. The characteristics of the composites were determined by using SEM, DSC, FTIR and TGA. SEM morphology showed the micro structure of silica fume/PCM. Also, thermal properties were examined by DSC and TGA analyses; and the chemical bonding of the composite was determined by FTIR analysis.
