Power consumption in the building thermal load could be the sum of the building fabric conduction load, building ventilation convection load and other such as radiation loss load. Dynamic Breathing Building (DBB) is the state-of-the-art to improve the wall insulation and indoor air quality(IAQ) performance as making air flow through the wall. This heat recovery type DBB contributes the power consumption saving due to the improved dynamic U-value. KIER twin test cell with static insulation(SI) and dynamic insulation(DI) at KIER was developed to test building power consumption at the real outside conditions. Then, the actual results were compared with the theory to predict the power consumption at the KIER twin test cell and introduced the building new radiation loss factor $\alpha$ to explain the difference between the both the theory and the actual case. As the results, the power consumption at the breathing DI wall building could saved 10.8% at the 2ACH(Air change per hour) compared with conventional insulation. The building radiation loss factor $\alpha$ for this test condition to calibrate the actual test was 0.55 in the test condition.

This study analyzes the relation of the consumption values and ethical fashion consumption behavior as well as other influential factors between Korean and German ethical consumers based on the 'Modified Theory of Planned Behavior.' A survey was conducted on female consumers in their 20s and 30s, who experienced ethical fashion consumption in Seoul and Berlin. A factor analysis, reliability analysis, F -test and multiple regression analysis were performed for model verification. The research results indicated that emotional value (in case of Korea) and functional value out of consumption values (in case of Germany) have significant effects in regards to the influence of consumption values on ethical self-identity. The effects of ethical self-identity on ethical fashion consumption behavior indicated that Korean ethical self-identity influenced the ethical fashion consumption behavior of moderating and simplicity and eco-friendly certification versus local consumption as well as above factors (in case of Germany) explained by ethical self-identity. Both variables had a negative moderating effect in Korea in regards to the moderating effects of social comparison and materialism in the relations of ethical self-identity and ethical fashion consumption behavior; however, only materialism was an influential factor in Germany. The results of the research variables by individualism/collectivism indicated that the horizontal-collectivism group showed the highest ethical self-identity along with the lowest materialism tendency that had a high point of consumption behavior towards local consumption. However, the vertical-individualism group was outstanding. The consumption behavior aimed at moderating and simplicity.

The purpose of this study was to analyze social, economic and cultural phenomena of the luxury brand in the viewpoint that the consumption system of the modern society stood for the sign consumption and the industrial production of difference as Baudrillard mentioned in the Consumer Society. The result was divided into the two subjects popularization and differentiation of luxury brand. Firstly the meaning of luxury brand was that the personal effects of consumption of king or aristocratic class who did not exist in the modern and were made into the selection and consumption-possible things of exchange value. The popularization of this sign was accelerated through TV drama. Secondly as differentiation strategy of luxury brand, was made by giving meaning to the life style concept of the upper class with advertisement and design, and also the logo of design was used as sign differentiated from people. Also the reason why the producer of the luxury brand gave meaning to such life style was that the awareness of the brand which people have consistently makes them consume more products. The consumption system of the modern society stood for the sign consumption, difference sign mark value which was the desire on a social meaning basis, not the consumption of things as used value. And the consumer could express his personality by selecting and consuming the product of luxury brand model made with this sign. Accordingly the distribution, purchase, sales and acquisition of the things with this difference sign were our verbal activity and linguistic code today, and it was the essential feature of the society, culture and economy of the consumer society.

Water is an essential resource for human survival. According to the OECD Environmental Outlook to 2050, rapid industrialization and a global population increase by approximately two billion will likely increase global water use by 55% in 2050. However, water depletion has been getting worse than before and has been happening more quickly, as Earth's water resources are limited. The present study proposes water management measures by using the virtual water theory which enables water consumption measurement and the confirmation and recognition of water scarcity problems, and will support the development of counter-measures. As a method for estimating the value of agricultural water, virtual water theory was used to calculate the amount of agricultural water input for domestic rice and to apply prices of agricultural water in the United States and China to Korean water prices. When the Chinese price was applied to Korean water prices, the value of agricultural water represented 0.3% of the Korean rice producer's price. When the US price was applied to Korean water prices, the value of agricultural water represented 1.6% of the domestic rice producer's price. The study exposes the percentage of the value of agricultural water in agricultural product prices, as well as how this scare resource may affect future prices. In the future, if there are water charges to effectively manage agricultural water, this study, which uses the virtual water theory, can be used as a preliminary research.

In recent high-performance superscalar processors, the result value of an instruction is predicted to improve instruction-level parallelism by breaking data dependencies. Using those predicted values, instructions are speculatively executed and substantial performance can be gained. It, however, requires additional power consumption due to the frequent access and update of the value prediction table. In this paper, first, the trade-off between the performance improvement and the increased power consumption for value prediction is measured and analyzed. And, in order to reduce additional power consumption without performance loss, the technique of controlling speculative execution with confidence counter and predicting useful instructions is developed. Also, in order to prove the validity, a tool is developed that can simulate processor behavior at cycle-level and measure total energy consumption and power consumption per cycle.

The primary purpose of this study is to identify determinants influencing Vietnamese consumers' purchase intention towards Japanese convenience goods. The research model consisting of six factors affecting the dependent variable is proposed based on the Theory of Consumption Values and Theory of Perceived Value of purchase. This study employs a survey method in a convenient sampling method to collect data of target respondents. Data consisting of 180 samples was collected and analyzed using the SMARPLS3 software. The measurement model is assessed to confirm the validity and reliability of the construct, then hypotheses testing is performed with Bootstrapping analysis. The results demonstrated that five factors affect Vietnamese consumers' purchase intention towards Japanese convenience goods, including the price of the product, quality of the product, functional value, emotional value, and conditional value. Major findings of this study suggest that the functional value that consumer perceives about Japanese convenience goods has the most significant relationship with their purchase intention, followed by the quality of the product and the price of the product. Besides, emotional value and conditional value have a moderate influence on consumers' purchase intention. Whereas the influence of the epistemic value of the product on consumers' purchase intention is insignificant in this presented study.

The purpose of this study is to identify selection attributes, functional benefits, psychological benefits, and values according to crossover shopping patterns (showrooming and webrooming). To achieve objectives of this study, a survey was designed based on the means-end chain theory, using the in-depth laddering technique and APT laddering technique which understanding the linkage of A(attributes)-FB(functional benefits)-PB(psychological benefit)-V(value). These two laddering techniques were used to construct a hierarchical value map (HVM) by linking selection attributes, functional benefits, psychological benefits, and value levels. The selection attribute items that showrooming shoppers consider important are 'price conformity', 'product information', 'product variety', and 'delivery service'. Functional benefit items were 'free purchase', 'economic benefit', 'communication', 'safety', and 'accurate Information', and psychological benefit items were 'convenience', 'relaxation', 'pleasure', 'rational consumption', and 'stability'. Finally, the value items were 'self-satisfaction', 'abundant life', 'achievement', 'happiness', and 'reasonable life'. Next, the selection attribute items that webrooming shoppers consider important are 'price conformity', 'product information', 'product variety', 'AS', 'shopping atmosphere', and 'seller service'. Functional benefit items were 'free purchase', 'economic profit', 'expression opinion', 'safety', and 'accurate information', and psychological benefit items were 'convenience', 'relaxation', 'rational consumption', and 'stability'. Finally, the value items were 'self-satisfaction', 'abundant life', 'happiness', and 'reasonable life'.

YouTube exhibits a hybrid personality, incorporating traits of both over-the-top (OTT) and personal broadcasting platforms. However, limited research has investigated these hybrid characteristics, particularly in the context of paid YouTube channel memberships. Therefore, building upon consumption value theory and prior literature, this study examines the influence of consumption value factors associated with paid YouTube channel memberships on usage satisfaction and continuance intention. Specifically, the study identifies four perceived consumption value factors (functional, social, emotional, and epistemic values) within the paid YouTube channel membership context and assesses their impact on usage satisfaction and continuance intention. Additionally, the study explores the moderating role of conditional value (the experience of watching live streams on paid YouTube channels) in these relationships. Data was collected via an online survey from Korean adults who subscribed to multiple paid YouTube channel memberships, resulting in 274 responses. The proposed hypotheses were tested using structural equation modeling (SEM). The SEM results indicate that all four consumption value factors significantly influence usage satisfaction, with usage satisfaction in turn positively affecting continuance intention. Furthermore, the study reveals that conditional value moderates the relationships between functional/emotional values and usage satisfaction, as well as between usage satisfaction and continuance intention. This study is the first to focus on YouTube channel paid memberships, which encompass characteristics from both OTT and personal broadcasting platforms. It is anticipated that this research will offer insights to personal broadcasters and stakeholders regarding the motivational factors that impact user satisfaction and encourage subscriptions to channel memberships.

This study aimed to understand the value pursued when consuming performances for classical music performance audiences, to identify the difference in influence by type, and to expand into the base of academic research focusing on audiences who are consumers in classical music performances, which was the existing supplier-centered. Also, this study tried to verify the effect of consumption value on flow and satisfaction. and we aimed to prove whether consumption value leads to re-spectating intention through structural relationship. For this purpose, a survey was conducted on the audience who watched classical music performances within one year by applying consumption value theory, and the analysis was conducted using smartPLS 3.0. As a result, functional value and emotional value had an effect on flow. The second one is that functional value had a positive effect on satisfaction. The third fact is that social value had a negative effect. Overall, the structural relationship between flow, satisfaction, and re-spectating intention had a strong effect on each other. Implications of this study are that the market characteristics and current status of classical music performances were examined, and that an effective marketing strategy to increase the re-spectator rate was sought by finding out the factors of audience's consumption value that affect viewing satisfaction.

Despite the importance of prenatal nutrition, many studies find inadequate calcium intake among pregnant women. The purpose of this study was to investigate the value of the Theory of Planned Behavior in explaining the intentions and the actual consumption of milk among pregnant women participating in or eligible for WIC. A cross-sectional survey was conducted to collect information regarding attitudes, subjective norms, perceived control, milk allocation within the family, intentions and consumption of milk. The survey questionnaire was developed using open-ended questions and interviews with 112 pregnant women. One-hundred-eighty women recruited from prenatal clinics completed the survey questionnaire. Multiple regression was used separately to investigate the association of factors to intentions and to the consu-mption of milk, as proposed in the theory. Milk allocation within the family was used as an exploratory variable to explain milk consumption. Study findings revealed that all three factors, attitudes, subjective norms and perceived control contributed to the model in explaining intentions (explained variance : 36.2%), with perceived control being most important. For milk consumption, intentions and perceived control were related significantly to actual consumption, while milk allocation within the family was not (explained variance : 44.6%). These findings suggest that perceived control is important in understanding both intentions and milk consumption, providing empirical evidence for the Theory of Planned Behavior. With respect to the role of perceived control, more strong evidence was provided in explaining intentions. Findings suggest that educational interventions to increase milk consumption among pregnant women should incorporate strategies to enhance the perception of control, and to strengthen positive attitudes and to elicit social support from significant other.
