In our society, consumers and enterprises work in cooperation for the continuous development and growth of society as well as construct effective and ethical measures. One of the representative examples are customercentered management activities in corporations, social responsibility activities, and sustainable ethical consumption that show consideration for the consumer's environment. The ethical consumption behavior of consumers becomes a virtuous circle that influences other consumer's ethical decision making by creating an ethical consumption culture. Furthermore, the cost and effort to solve non-ethical consumption problems can be solved. This research aims at aspiring the perception of consumer's ethical consumption and finding measures to increase ethical behavior. This paper further investigated the consumer's ethical consumption behavior, personality traits, perception of consumption society, and ethical judgements. For the research, a structured survey was conducted on 300 university students in Seoul. SPSS ver. 21.0 and AMOS ver. 18.0 programs were used for statistical data analysis. The results indicated differences in variables that influence consumer's ethical consumption behavior (fair trade, boycotts, and environmentally friendly products). In particular, it was evident that ethical judgements (such as the agent, personality traits, and perception consumption society) have different direct and non-direct influences on ethical consumption behavior. Strengthening the management of factors that influence measures that increase university student's ethical consumption behavior in direct and non-direct ways, providing education and improving information are believed effective in increasing ethical consumption behavior.

The outline of general trend on production, consumption and price of non-ferrous metals during 1969 is summerized in the paper. The production of every non-ferrous metals has increased compare to that of last year, and their consumption except silver has also increased. Specially the rate of growth of production is that; The rate of growth of consumption is such; The prices of gold and silver have decreased since last November due to the stability of international currency and the creation of S.D.R. at I.M.F., but those of other metals have increased, marking the price at the end of 1969 as follows: Cupper price of Foreign Refinery showed ¢72.471/lb(increased 39% per year), lead and Zinc jumped up to the highest price since the Korean War (1951-1953), showing the lead price ¢16.50/lb (increased 27% per year) and the zinc price ¢15.50/lb (increased 15% per year). Price of tungsten was higher than the agreed price that was made between Korea and U.S.A. during 1951 through 1954, showing $63.4/S.T.U. (increased 13% per year). The price of molybdenum was slightly increased from $1.62 to $1.72 (increased 6% per year). In summing up, the year of 1969 was the golden age for the nonferrous metals. It is, hawever, expected that in the next few years, the consumption rate and the prices of non-ferrous metals will be declined compared to those of 1969.

The paper examined the relationship between total and sector level electricity consumptions and economic growth in Korea for the period of 1980-2009. The results of unit-roots and cointegration tests show that all variables-real GDP, total, primary, manufacture, and service sector electricity consumptions-were not stationary and there were no linear combinations in the long run between electricity consumptions and economic growth. Thus, by using standard Granger-causality test we found that total, primary, and manufacture sector electricity consumptions were Granger-caused by economic growth, not vice versa. This means that causality runs from economic growth to each electricity consumption. However, there is no causal relationship between service sector electricity consumption and economic growth. These results imply that the government policies aimed at reducing electricity consumptions and increasing energy efficiency etc. can be feasible without deterring economic growth in Korea.

Purpose: This study is to analyze the changes of consumption patterns to diagnose the economic impacts on consumers' market during COVID-19, and to suggest implications to overcome the new social and economic crisis of Jeju Island. Research design, data, and methodology: We collected a set of credit card transaction records issued by BC Card Company from merchants in Jeju Special Self-Governing Province for past 4 years from 2017 to 2020 from the Jeju Data Hub run by Jeju Special Self-Governing Province. The big data contains details of approved credit card transactions including the approval numbers, amount, locations and types of merchants, time and age of users, etc. The researchers summed up amount in monthly basis, transforming big data to small data to analyze the changes of consumption before and after COVID-19. Results: Sales fell sharply in transportation industries including airlines, and overall consumption by age group decreased while the decrease in consumption among the seniors was relatively small. The sales of Yeon-dong and Yongdam-dong in Jeju City also fell significantly compared to other regions. As a result of the paired t-test of all 73 samples in Jeju City, the p-value of the mean consumption of the credit card in 2019 and 2020 is significant, statistically proven that the total consumption amount in the two years is different. Conclusions: We found there are sensitive spots that can be strategically approached based on the changes in consumption patterns by industry, region, and age although most of companies and small businesses have been hit by COVID-19. It is necessary for local companies and for the government to be focusing their support on upgrading services, in order to prevent declining sales and job instability for their employees, creating strategies to retain jobs and prevent customer churn in the face of the crisis. As Jeju Province is highly dependent on the tertiary industry, including tourism, it is suggested to create various strategies to overcome the crisis of the pandemic by constantly monitoring the sales trends of local companies.

The juvenile gobiidae, Tridentiger trigonocephatus were reared for 40 days under the salinity ranges between 0 and 33.6$\textperthousand$ to examine the effects of salinity on the survival, growth and oxygen consumption rates of the fish. Survival rates were significantly declined for the fish reared under 3.4$\textperthousand$, and daily growth rates were also reduced below 6.7$\textperthousand$ Body length and weight of gobiids reared below 6.7$\textperthousand$ were smaller than those reared above 13.4$\textperthousand$. Oxygen consumption rates in the salinity conditions $\leq$ 10.1$\textperthousand$ were significantly reduced with decreasing salinity. This study reveled that low salinity reduced survival, growth and oxygen consumption rates of the juvenile gobiids suggesting potential influence on the natural mortality of Tridentiger trigonocephalus in the estuarine areas where experience the extreme salinity fluctuations in Korean waters.

Due to the growth of the preschooler clothing industry, significant research has been conducted on the pursued benefits, purchase behavior, and purchase intension related to preschooler clothing; however, reports on the consumption value of preschooler clothing remain limited. This study provides a consumption value for preschooler clothing through qualitative research. A total of 15 mothers of preschoolers aged 1-6 years old were interviewed on the consumption value of preschooler clothing. The subsequent consumption value of preschooler clothing consisted of 9 major factors (vicarious satisfaction value, social display/image value, safety value, convenient value, economic value, distinguishable value, expressive-aesthetic value, fashionable value and conditional value). In addition, the vicarious satisfaction value, social display/image value, safety value, and convenient value were new-expressed values that differed from previous reports on the consumption value of adult clothing.

This study examines the factors influencing e-sports product consumption among Chinese e-sports game players. We focus on the popular game "King of Glory" and use surveys to collect player data. Our findings show that e-sports product characteristics significantly impact consumption experiences, while incentive factors also influence consumption willingness. External factors have minimal impact. Additionally, souvenir products and festival events are key in driving e-sports consumption. This research explores the consumption willingness of Chinese e-sports players, the world's largest consumer market. Understanding their needs can help companies develop targeted marketing strategies, unlocking the commercial potential of e-sports and promoting industry growth.

This research examined consumption-based carbon emission reduction by nuclear energy consumption and environmental tax while considering the context of trade globalization in the highest five emitter nations from 1990 to 2020. This study used various empirical methodologies, including preliminary analysis to check the stationarity and cointegration, the CS-ARDL for long-run analysis, CCEMG, AMG for robustness, and the D-H causality test for short-term pairwise causation. The results indicated that nuclear energy consumption, environmental tax, and trade globalization help to mitigate consumption-based carbon emissions while economic growth and population density boost carbon emissions. Furthermore, the results also found two-way casual connection exists between nuclear energy consumption, population density, and consumption-based carbon emissions. Thus, the results emphasize the need for government policies that encourage nuclear energy and environmental tax as a strategy to reduce carbon emissions and achieve and maintain environmental development.

This paper analyzes the relationships among the energy consumption, renewable energy production, real gross regional domestic product(GRDP), and greenhouse gas(GHG) emissions. It uses the metropolitan city and province level data for Korea from 2010 to 2018, employing a panal vector autoregressive(VAR) model. We find that an increase in energy consumption has a limited impact on boosting renewable energy production or gross regional domestic product, while it leads to an increase in greenhouse gas emissions. A rise in renewable energy production can increase gross regional domestic product, but it has no meaningful effects on energy consumption and the reduction of green house gas emissions. Our finding indicates that it is crucial to expand the supply of renewable energy as well as to decrease energy consumption in order to achieve the goal of reducing greenhouse gas emissions and reaching economic growth.

The purpose of this study was to investigate changes in Korean meat consumption as well as meat consumption trends. During the Japanese occupation period, the supply of meat was considerably insufficient. However, meat consumption mainly in large cities has gradually increased. Especially, 'Pyeongyang cow', a specialty of Pyeongyang, started being raised as edible beef cattle in 1933. During the chaotic period following liberation from Japan, the price of meat sharply increased. However, as the meat supply stabilized, the 'beef grade system' was introduced in 1967. Since then, beef has sold according to region. During the early economic growth period of the mid-1970s, meat consumption rapidly increased, and foreign beef was first imported in 1976. The preference for beef was somewhat attenuated due to the outbreak of mad cow disease and economic slowdown of the 1990s, resulting in an increase in the consumption of pork, a replacement meat. During the recent period of economic development, meat consumption has somewhat fallen and remained low. In late 2003, with the occurrence of mad cow disease in the US, the demand for pork, and especially pork fatback, has sharply increased.
