In the theater-based movie industry, it is known that the diversity of movie consumption is hindered due to concentrated consumption. This study extends the existing discussions on the concentration of movie consumption in theaters to the concentration of online movie consumption. In addition, the study analyzes the impact of Covid-19 pandemic on movie consumption and the concentration thereof. For analysis, panel data for the period from 2012 through 2021 were collected by utilizing the box office data of the Korean Film Council. As a result of the analysis, it was found that the concentration of consumption by movie, country, and genre was higher in theaters than online. Further, the concentration of movie consumption has increased both in theaters and online until the outbreak of Covid-19 pandemic. During the Covid-19 pandemic period, the size of consumption has decreased both in theaters and online, while the concentration of consumption by movie online has increased. The result of this study implies a need for policy-level efforts to convert the trend of consumption concentration for long-term development of the movie industry with secured diversity of movie consumption, and for this, the study suggests that the use of online media would be useful.

The purpose of this study was to analyze factors that influence consumption pattern of snacks of middle school students. The subjects of study were 607 middle school students (male: 316, female: 291) in Ilsan area. The subjects were surveyed by a self-administered questionnaire about anthropometrics, mother's employed status, parents' education level, and snack consumption pattern. Male students showed higher consumption in 'milk and milk products' (p<0.05), 'instant noodles' (p<0.01), and 'cereal' (p<0.05). In the other hand, female students showed higher consumption in 'biscuits, cookies' (p<0.01) and 'candy and chocolates' (p<0.01). Subjects in underweight group showed higher frequency in the consumption of 'biscuits, cookies' (p<0.05) and 'candy and chocolates' (p<0.001) compared with normal weight or overweight subjects. The subjects with mother not having a job showed higher consumption of snacks under controlling parents (p<0.001), and higher consumption in 'fruit and fruit juice' (p<0.05) and 'milk and milk products' (p<0.01) compared to the subjects with mother having a job. The subjects with parents having higher education level showed higher of consumption in 'fast food'. These results suggest that general characteristics of the subjects and characteristics of family environment may affect consumption pattern of snacks in middle school students.

The purpose of this study is to identify antecedent factors influencing the two-sided consumption intention tendencies observed in MZ generation from the viewpoint of consumption value in the cosmetic consumption scene of fashion houses. In order to verify the research model and hypotheses proposed in this study at the level of statistical significance. a survey was conducted for MZ generation, and data collected from a total of 286 samples were analyzed through a structural equation model. As a result. emotional and social consumption value was identified as a variable that had a great influence on the consumption intention of MZ generation. First, self-esteem had an effect on the emotion consumption value at the statistical significance level. Second, materialism had a significant influence on emotional and social consumption values. Third, public self-consciousness was found to have an effect on social consumption value. That is, MZ generation pursues the beauty trend presented by the fashion house's beauty brand and perceives it as a high consumption value. In addition, it was confirmed that MZ generation exhibited a conspicuous consumption tendency that they could be socially differentiated by using fashion house cosmetics.

Measuring the food safety has been focused only on the psychological consumers' recognition of food safety. The actual measurement tool should consist of the evidence-based statistical data to assess the level of national food safety in scientific perspectives. This paper described the development of a concept to measure the food safety of the food chain based on OECD PSR framework. This paper discusses the elaboration of a set of 8 food safety related data issued as statistical data, and which were same weighted. These food safety statistical data (FSDs) were derived as the basis of measuring the variation of food safety during 2013-2019. The values of the primary production indicator (PPI), the processing and manufacturing indicator (PMI), and the distribution and consumption indicator (DCI) are 0.558-0.859, 0.533-0.691, and 0.979-0.982, respectively. The food safety status (FSS) derived from the safety indicator values of each of the three stages is 0.700-0.810. In order to increase the level of food safety, it is necessary to pay attention to PMI and PPI management. In the future, continuously calculating the level of food safety, managing it like the level of psychological safety, and further expanding it to the level of food safety between countries will help establish policies to improve the level of food safety in Korea.

Methylmercury (MeHg) is an environmental pollutant with neurotoxic effects on the central nervous system. The major exposure route of MeHg to humans is via consumption of fish and shellfish which accumulate the chemical through the food web in an aquatic environment. Hair mercury level is an excellent marker for MeHg exposure. We have been conducting a survey on hair mercury contents among general populations from 14 districts to estimate the current Japanese MeHg exposure level. Total mercury levels of all hair samples collected (12923 in total) were analyzed by the oxygen combustion-gold amalgamation method using an atomic absorption mercury detector. Multiple regression analysis revealed that mercury levels were significantly correlated with several covariates, such as sex, age, the amount of daily intake of total fish/shellfish, a preference for certain fish such as tuna or bonito, and artificial waving. The geometric means for the population without artificial waving were 2.47 and 1.65 ${\mu}g/g$ for males (n = 5623) and females (n = 3470), respectively. Hair mercury levels varied with age, and the variations were more significant in males. Since the difference between sexes was not evident at younger ages, some hormonal control might also be involved in the mercury uptake by human hair. The average mercury levels in our hair samples varied among the sampling districts. Tuna is a major carnivorous fish with high mercury accumulations that is often consumed in Japan. The amount of fish consumption and the preference rate far tuna would appear to be responsible far the regional variation in hair mercury levels in Japan. Recently, a provisional tolerable weekly intake (PTWI) of MeHg was revised by 61st JECFA to 1.6 ${\mu}g/kg/week$, which was about half that of the Japanese standard, and corresponded to a hair level of 2.2 ppm. The distribution of hair mercury levels in Japanese populations in the present study indicated that 25% of the Japanese females of child-bearing age were estimated to be exposed to MeHg over the PTWI level. This would reflect the high Japanese consumption of marine products. However, not only mercury contamination, but also the nutritional benefit may have to be considered when discussing the risk involved in the current level of fish and shellfish consumption in Japan.

This study examined college students' propensity for materialism and conspicuous consumption, and their preference for imported-luxury brand products. This study also identified the factors that influence college students preference for the imported-luxury brands. The data were obtained from a questionnaire completed by 4-year-college students (N=309), and were analyzed by t-tests, ANOVA, and multiple regression analyses. The findings of this study are as follows: First, college students' propensities for both materialism and conspicuous consumption were a little higher than the middle points of the scales. Their preference for imported-luxury brands was a little below the middle point of the scale. Second, the propensity for materialism was higher among first- and second-year students than among third- and fourth-year students. The occupation of household head was significantly related with the levels of materialism and conspicuous consumption, as well as the preference for imported-luxury brand products. Female students were more likely to prefer imported-luxury brands. Those with a higher income and subjective level of living were more likely to have the propensity for conspicuous consumption and preferences for imported-luxury brands. Third, the imported-luxury brands preferences were positively associated with the propensities for both materialism and conspicuous consumption.

The purpose of this study was to investigate the nutrient intake status and factors affecting the consumption of commercial staple food for Korean adults using the Korean National Health and Nutrition Examination Survey data from 2010 to 2014. As a result of analyzing the frequency of consumption of commercial staple food, in 27.578 subjects, 75.5% of them did not eat it once a day, 21.7% of the subjects consumed once a day, and more than two times showed 2.8%. According to the results of age, the higher the age, the higher the rate of not consuming commercial staple food, and the lower the age, the higher the rate of consumption of commercial staple food(p<0.0001). In addition, the rate of consumption of commercial staple food was higher in cities than in rural areas. The higher the education level, the higher the proportion of commercial staple food. The intake of rice, noodles, and bread increased significantly as the frequency of consumption of commercial staple foods increased. Protein, fat, riboflavin, and niacin showed significant differences with increasing frequency of commercial staple food in nutrient intakes(p<0.0001). As the number of commercial staple food increased, the intake of grains, egg products, milk and dairy products, beverages and other food groups increased and the consumption of vegetables decreased significantly.

The relationship between socio-economic status and food and nutrient consumption patterns was studied in 7,370 Koreans aged 20 years and older in the 1995 Korean Health and Nutrition Survey. The aim of this study was to investigate the effect of rapid economic growth on food and nutrient consumption for Korean adults in the last 30 years. Monthly household income, and individual's educational level and occupation were chosen as variables of socio-economic status for individuals. A one day 24 hour recall method was used for the dietary survey. One way analysis of varience was adopted to test tole association between socio-economic variables and food and nutrient consumption patterns. Individuals who had a high socio-economic status had significantly higher daily intake of most of the nutrients including calcium, vitamin A, vitamin B$_2$which reached above the recommended dietary allowances(RDA) and a higher percentage energy consumption from fat. In addition, individual who belonged to a low socio-economic status consumed less animal foods, including meat, egg, milk and consumed low proportion of energy from fat. The results suggest that in spite of rapid economic growth during the last 30 years in Korea, individuals who belonged to low sorio-economic status categories are still nutritionally vulnerable. Among the sorio-economic variables, income and education except occupation were the influential factors on the food and nutrient consumption of Koreans. Therefore, nutrition policy should focus on influencing the dietary patterns of lower social class individuals to improve the health status of the population as a whole.

Security of a power system refers to its robustness relative to a set of imminent disturbances (contingencies) during operation. The socially optimal solution for the actuall level of generation/consumption has been well-known spot pricing at shot-run marginal cost. The main disadvantage of this approach arises because serious contingencies occur quite infrequently. Thus by establishing contractual obligations for contingency offering before an actual operation time through decision feedback we can obtain socially optimal level of system security. Under probabilistic precontract pricing the operating point is established at equal incremental cost of the expected short-run and collapse cost of each participant. Rates for power generation/consumption and for an offer to use during a contingency, as well as information on the probability distribution of contingency need for each participant, are derived so that individual optimization will lead to the socially optimal solution in which system security is optimized and the aggregate benefit is maxmized.
