The high caffeine intake by adolescents has been a concern. The purpose of this study was to examine the awareness and consumption of caffeine-containing foods among 443 high school students using a questionnaire. An analysis of the spending patterns of the students' weekly allowance showed that the amounts spent on purchasing caffeine-containing foods were higher for female students than male students (P <0.001). The scoring of the perception of caffeine was 3.1 out of 5, interest in the caffeine content of food was 2.6, consumption of caffeine-containing foods was 2.6, and usefulness of caffeine-containing foods was 2.7. The awareness of caffeine content in food was significantly higher in females (7.3 out of 11) than male students (6.7) (P<0.01). Approximately 59% of students perceived that the relationship between caffeine-containing foods and health, was harmful, and the experience of side effects after taking caffeine was significantly higher in female students than males. These side effects include heartburn (P<0.001), headache or dizziness (P<0.001), irregular heartbeat (P<0.05), and hands and feet shake (P<0.01). Caffeine-containing foods were purchased at convenience stores (62.1%). The factor considered when purchasing caffeine-containing foods was taste (72.2%), and the use of nutrition labeling for caffeine-containing foods scored 2.0 out of 5 points. When assessing the intake of caffeine-containing foods, the foods consumed more than once a week were in the order of coke, chocolate, chocolate milk, chocolate pie, and chocolate bars. These results suggest that it is necessary to prepare a caffeine-related nutrition guide improvement by sales management, and strengthen food labeling standards for the desirable recognition of caffeine and its safe intake by adolescents.

Purpose: With increased time spent at home due to prolonged online classes, this study sought to determine how the coronavirus disease 2019 (COVID-19) pandemic has impacted the mukbang- and cookbang-watching patterns and dietary life of college students. Methods: All students majoring in food and nutrition (FN) at a college in Gyeonggi, Korea, participated in the survey in April 2019 (M/F = 36/106) and June 2020 (M/F -37/130) and data were analyzed using SPSS 26.0. Results: Compared to students responding in 2019, those in 2020 reported more frequently eating alone (p < 0.01) and cooking (p < 0.01), and evaluated their diets better regarding pleasant mealtimes atmosphere (p < 0.05), moderation in drinking (p < 0.05), and not consuming excessively delivery foods (p < 0.001), processed foods (p < 0.01), foods with animal fat (p < 0.01), salty foods (p < 0.01), and sweets (p < 0.01). Although the proportion of respondents who answered that they watched mukbang and cookbang at least occasionally did not change, greater proportions of respondents reported watching both genres frequently (p < 0.001, respectively) and spending less time/day in watching mukbang (p < 0.05) in 2020 vs. 2019. While they evaluated the effect of mukbang- and cookbang-watching on overall diet similarly, the proportion of respondents that reported feeling as though mukbang-watching prompted them to eat more of less-desirable foods decreased from 54.3% to 41.5% (p < 0.05). Diet improvement of participants due to COVID-19 resulted in that the association between frequent mukbang-watching and unhealthier dietary habits in 2019 was not shown in 2020. Conclusion: Our results suggest that the prolonged at-home stays due to COVID-19 might have improved many aspects of diet and decreased undesirable effect of frequent mukbang-watching in case of college students majoring in FN.

최근 미국드라마가 지상파와 케이블 텔레비전을 통해 젊은 수용자들에게 급속히 확산되고 있다. '미드'라고 불리는 미국드라마는 인터넷을 통한 파일 공유로 미국에서 방영되고 있는 드라마까지 실시간으로 유통되어 대학생들 사이에 새로운 미드문화를 형성하고 있다. 본 연구는 이러한 미국 텔레비전 드라마 시청동기 구조와 만족도를 발견하고, 이를 바탕으로 한국드라마와 비교분석하였다. 아울러 대학생들의 미국드라마 시청만족도 요인이 한국 텔레비전 시청 형태에 어떠한 영향이 미치는가에 대한 분석도 실시하였다. 분석결과 미국드라마 시청동기 구조는 '오락과 휴식', '정보 획득', '환경/동반자', '성적 흥미' 등과 같이 4개의 인자로 구성되었다. 이와 반면에 한국드라마 시청동기 요인은 미국드라마 시청 요인에 '드라마 특성'과 '습관적 소일'이 추가되어 모두 6개의 인자로 나타났다. 만족도의 경우, 두 나라 드라마 시청자를 경시청자와 중시청자 집단으로 나누어 비교한 결과 미국드라마 5개의 요인 중 3개 요인이, 한국드라마는 2개 요인에서 유의미한 차이가 나타났다. 미국드라마 만족도가 한국 텔레비전 시청 형태에 미치는 영향에 관한 분석에서 대부분의 만족도 요인은 시청 형태와 관계가 유의미한 것으로 나타났으나, 미치는 영향력은 매우 낮은 것으로 나타났다.

Objectives: Time-activity studies have become an integral part of comprehensive exposure assessment and personal exposure modeling. The aims of this study were to estimate exposure levels to nitrogen dioxide($NO_2$) and volatile organic compounds(VOCs), and to compare estimated exposures by using time-activity patterns and indoor air concentrations. Methods: The major microenvironments for office workers were selected using the Time-Use Survey conducted by the National Statistical Office in Korea in 2009. A total of 9,194 and 6,130 workers were recruited for weekdays and weekends, respectively, from the Time-Use Survey. It appears that workers were spending about 50% of their time in the house and about 30% of their time in other indoor areas during the weekdays. In addition, we analyzed the time-activity patterns of 20 office workers and indoor air concentrations in Daegu using a questionnaire and time-activity diary. Estimated exposures were compared with measured concentrations using the time-weighted average analysis of air pollutants. Conclusions: According to the time-activity pattern for the office workers, time spent in the residence indoors during the summer and winter have been shown as $11.12{\pm}2.20$ hours and $12.48{\pm}1.77$ hours, respectively, which indicates higher hours in the winter. Time spent in the office in the summer has been shown to be 1.5 hours higher than in the winter. The target pollutants demonstrate a positive correlation ($R^2=0.076{\sim}0.553$)in the personal exposure results derived from direct measurement and estimated personal exposure concentrations by applying the time activity pattern, as well as measured concentration of the partial environment to the TWA model. However, these correlations were not statistically significant. This may be explained by the difference being caused by other indoor environments, such as a bar, cafe, or diner.

This study has carried out scanning tests in order to figure out the features of scanning search by sex of space users, with the result of which the validity of data has been estimated. In this research, the scanning patterns were set up for verifying the typology of scanning paths and then the reason for determining scanning paths and the validity of estimation method were reviewed. Since the observation features depends on sex, the analysis of visual activities for acquiring any information in a space will reveal the intention and purpose of space users. The findings by analyzing the features of scanning pattern by sex which were found at the determination of scanning patterns can be defined as the followings. First, for estimating the process of space-information search, the movement distance at each point of continuative-observation data from the angle of eye-movement has been extracted, on the ground of which the fixation and movement of eye have been defined for the establishment of scanning-cut characteristics. Second, the scanning times were estimated for the extraction of effective observation data that would be used for comparative analysis, which showed that men had more data (3,398.2/64.4%) than women (2,998.2/55.6%). This enables the acknowledgment that the scanning cut of men was relatively less, which indicates that men will acquire more information on space than women in the process of observing any space. Third, men's scanning times (58.0 times/2.02 seconds) were less than those of women (71.9 times/1.39 seconds) while the scanning time of the former was longer than that of the latter, which shows the feature that it takes longer for men than women in scanning while the scanning times of the former is less than those of the latter. Fourth, the observation features can be determined that the combination of this result with the predominance character by sex for a general viewpoint to be employed indicates that while men employ mixed-scanning for observation activities to acquire space-information spending for longer time, women, by concentrated-scanning, focus on a single point for shorter time or stay at one location for a considerably long time for space-information acquirement.

The aims of this study are to establish a mode of housing life style that meet the demands of families living in big cities, and the contribute to the development of a better housing life style pattern by considering metropolitan residents' choice of housing and basic concepts of their behavioral patterns. The results of this study were as follows: 1. Value orientation of family life was divided into value orientation of family and value orientation of housing. Value orientation of family was constituted of four factors such as 'harmony', 'leisure and hobbies', 'individual development and its support' , 'education' . Value orientation of housing is constituted of three factors such as 'physical characteristics of house' , '\`environmental condition', 'socio-economic conditions of housing'. The comprehensive life values were constituted of six factors such as 'the importance of communal family', 'the importance of housing decoration and housing life benefits', 'the importance of security and holding environment' , 'the importance of familial harmony', 'the importance of privacy', 'the importance of convenience and natural environment'. Based on three factors, were found to be fine types of value orientation of family life which were 'pursue healthy of family', 'comfort of family', 'clean environment', 'convenient environment', and 'harmonious relationship among family members'. Variables influencing the value orientation of family life were property and price of housing. 2. Consumption propensity when buying house, furniture and durables were constituted of four factors which were propensity to 'beauty', 'fashion', 'tradition and symbol', and 'pragmatic use'. Based on these factors, there were found to be four types of consumption propensity when buying house, furniture and durables which were 'fashion', 'tradition and symbol', 'beauty', and 'pragmatic use'. Variables influencing spending habits were found to be objective social class (SES), types of residence, wife's educational background, and price of housing. 3. Propensity to using space were constituted of three factors which were 'convenience', 'politeness and social grace', and 'housekeeping'. Based on these factors, there were found to be three types of propensity to using space which were 'individuality', 'convenience', and 'politeness and housekeeping'. Variables influencing propensity to use of space were found to be objective social class (SES), wife's educational background, types of homeownership and price of housing 4. According to this study, there were found to be six patterns of housing life style: 1) family that seeks formalist life, 2) family that seeks harmonious life, 3) family that seeks active healthy life, 4) family that combine various factors, 5) family that seeks convenience, 6) family that stresses environment.

As men in their 30s are spending more money on clothing, it is becoming increasingly important to first conduct an anthropometric study and then develop garment patterns accommodating the changes found in body sizes and types of men in their 30s, in order to effectively address their fit dissatisfaction. Thus this study aims to explore changes in upper body sizes and body types of men in their 30s, which provide basic measurements for designing major garment items including jackets and shirts. To this purpose, key anthropometric dimensions of the upper body of men in their 30s, taken from the 6th (2015) and 7th (2016) surveys conducted by Size Korea, were analyzed using SPSS 24.0 for Windows. Independent sample t-tests were conducted on major upper body sizes to track changes with measuring time. Factor and cluster analyses were used to classify body types. By comparing the two surveys, it was found that the overall body sizes of men in their 30s were increasing in height-related items, circumference, thickness, and width, -as well as body weight and BMIs. Upper body height-related items, in particular, showed a higher average value in the 6th survey than in the 7th, indicating that the overall body types of men are becoming "westernized" with longer legs and shorter torso. Finally, five factors were derived to determine the typical upper body types of men in their 30s and the body types were classified into three categories according to the cluster analysis. First, those with a relatively small build with short stature and torso. Second, those with the highest stature and vertical dimension with the smallest torso volume and least body fatness. Third, those with the biggest torso volume and most body fatness with bigger width between armpits and shoulders. The distributional pattern analysis showed that men in their 30s tend to have increasingly higher stature but lower body weight and BMIs than in the past, implying that their body types are becoming close to those of men in their 20s.

Recently, there has been a change in consumer culture. The paradigm is changing from a consumption model that used to emphasize rationality to an ethical consumption model that focuses on sustainability. Such a change in consumption patterns has also been seen in the cosmetics industry, but studies to empirically assess this trend are incomplete. Therefore, the purpose of this study is to empirically identify the impact of ethical consumption proprieties on attitudes and purchasing intentions for ethical cosmetics. To achieve the aim of this study, 506 adult women residing in Korea were selected as subjects and surveyed. To identify the demographic characteristics of the study participants, a technical statistical analysis and frequency analysis were conducted. To check the validity and reliability of the measuring tools, an exploratory factor analysis was performed, and the Cronbach's α factor was calculated. The analysis method was analyzed using the SPSS 25.0 and the Amos 25.0 statistical analysis programs. The results of this study are as follows. First, ethical spending tendencies had a positive impact on attitudes toward ethical cosmetics. Specifically, interest in ethical issues, altruism, and business ethics perception have had a positive impact on attitudes toward ethical cosmetics. However, consumer effectiveness had no significant impact on attitudes toward ethical cosmetics. Second, attitudes toward ethical cosmetics had a positive effect on purchasing intentions. This study found that for the spread of ethical cosmetics and ethical consumption trends varied according to the age and that attitudes toward ethical cosmetics and differences in purchasing intentions should be kept in mind. It also showed that attitudes toward ethical cosmetics affect purchasing intentions. The results of this study suggested that the analysis of adult women, the main consumers of cosmetics, by age was meaningful for finding the factors for growth in the macroscopic ethical cosmetics industry and that the industry could raise its ethical awareness. If such tasks are systematically established, ethical cosmetics are thought to be able to actively solve social problems and lead a mature cosmetics industry.

This study is to analyze Korean-Chinese women's Costume in Yabian with factors such as reform opening-up, economic growth, change of social values, development of technology, more education opportunities and influence of mass media. It divides the 1990's into two halves. Photos, interview, observation and relevant literature were used for this study. Even though economy grew rapidly, they needed to purchase daily goods other than clothes. In a way that they preferred practicality, it showed somewhat it was still developing. The trend in the first half of the 1990's was characterized : first, Synthetic or artificial fibers and ready-made suits were popular ; second, there still remained the men's style ; third, they wore Tanrikoo(彈力袴), Tisingkoo(體型袴), Jiaotakoo(脚袴) because of its properties of activeness and comfort ; fourth, shoulders looked ore prominent with pads as they were used in Chungsanfoo(中山服) ; fifth, clothes in grey and dark blue was in fashion ; sixth, they wore hand-made knit vests and sweaters and often mountain-climbing gears for its light and warm quality ; seventh, along with opening-up, various materials and colorful clothes were in style, which satisfied women's desire for beauty. They decorated Hanbok(韓服), using sleeves with colors, golden ornaments, flower patterns embroidery, materials of different color in collar and tie and dyes of sleeves and skirts. In the first half of the 1990's when the opening-up was beginning, there were diverse styles and colors in fashion, yet not close to good quality. As the economy grew, the second half of the 1990's was characterized by good palate, individuality, favouritism on foreign goods, rapid change of fashion. For instance, fur coat and woolen fabric were favored. Economic growth led to abundance of cloth, dyes and decorative materials. In addition, people possessed more clothing and it was possible for them to wear both Hanbok and wedding dress in wedding ceremony. People placed their standards on competency and financial ability rather than ideology. Worship disappeared and individuality arose. Therefore, apparel functioned not only as protection but as suits with aesthetic purpose. This resulted in introduction of bold style, imitation of western countries and extension of use of Hanbok. With the help of mass media, transportation, telecommunication, contact with Korean company and civilians, Korean and western cultures, through Korea, were accepted. Change in structure of economic status caused excessive spending and more educational opportunities that enabled people to accept foreign culture quickly. Values moved onto new, beautiful and better characteristics. it was possible to have suits ready-made due to improvement of mass production and cotten, wool, linen, silk became popular owing to technology. New technology, the bases of mass consumption, increased possession of clothing and accelerated change of fashion. In summary, women's Costume in Yanbian were affected by the factors in economy, politics, culture contact as well as change of society and technology.
