This study analyzed the expression effect of the crinoline-style female costume, which was popular in the Victorian Age based on the Delong theory, through the drama The Empress. Theatrical research was conducted through a documentary survey of advanced domestic and foreign studies. Next, this study used the over-the-top (OTT) drama The Empress as a research tool for visual media. The analysis of the expression effect based on the Delong theory showed that the Elizabethan costume in the drama was seen as the expression of excitement, calmness, strength, and delicacy, most of which were in agreement with the Delong expression effect. The effect of excitement was expressed more, compared to delicacy. Hence, it was concluded that the characteristics and role of the main character of Elizabeth were expressed well through the costume. The result of this study could be used as basic data for the research of period dramas of the 19th century as well as for the design and manufacture of drama or stage costumes for dramas depicting the Crinoline style of costumes.

This study explores the protective factors that influence positive school adjustment in early adolescents afflicted with subclinical and clinical sluggish cognitive tempo (SCT) tendencies. We further examine the relationship between the variables. Specifically, the study evaluated the simple mediating effect and serial multiple mediating effects of self-identity and academic failure tolerance in the relationship between parental attachment and school adjustment in early adolescents with SCT. The study utilized data from the 12th Korean Children Panel (2019). The mediation models were tested using Models 4 and 6 of the PROCESS Macro. Our results showed that self-identity completely mediates whereas academic failure tolerance partially mediates the relationship between parental attachment and school adjustment. The serial multiple mediating effects of self-identity and academic failure tolerance in the relationship between parental attachment and school adjustment were found to be significant. Additionally, only the indirect effect of the path ‘parental attachment ⟶ self-identity ⟶ academic failure tolerance ⟶ school adjustment’ was found to be significant.

This study examined the factors influencing online food purchasing (channel selection, purchasing share, and satisfaction with online food purchases) after the occurrence of coronavirus disease 2019 (COVID-19), using raw data from the 2021 Food Consumption Behavior Survey collected by the Korea Rural Economic Institute. The results of this study revealed that when it comes to selecting online stores (channels) for food purchases, consumers prioritized accuracy and promptness of delivery, stability of payment systems, and price. The reasons for choosing online food purchases were primarily for the convenience and efficiency offered, such as delivery services and their timesaving aspects. Additionally, consumers also considered superior product quality and variety as the advantages of online food shopping. Furthermore, in terms of online food purchasing behavior, the following were observed: First, consumers primarily use mobile devices for online food shopping. Specialized online shopping malls are the most frequently used distribution channels for primary food purchases online. Additionally, when analyzing the factors influencing the choice of the online food purchasing channel (Personal Computer [PC] vs Mobile Phone), BMI (Body Mass Index) was found to be a significant factor influencing the choice. Second, the proportion of online food purchases was reported to be higher or constant compared to the previous year, and the factors influencing this trend were concerns about the influx of food from external sources and motivations, gender, income, household size, seniors. Third, when analyzing the factors influencing overall satisfaction with online food purchases, it was found that the proportion of online food purchases, satisfaction with price and quality, concerns about external food, motivations, and generations were significant factors.

This study examines the satisfaction with medical institutions by considering the type of medical usage satisfaction with medical institutions. The subjects were 1,251 single elderly households living in rural areas. Raw data was procured from the ‘Survey on Rural Well-being in 2021’. A stepwise regression analysis was conducted to identify the factors influencing satisfaction with medical institutions. Significant differences were obtained in satisfaction with medical institutions based on various factors, including educational background, monthly health care expenditure, happiness with life, subjective health status, satisfaction with own health status, health comparison with similar age groups, health status compared to the previous year, number of visits to medical institutions, means of transportation to medical institutions, required time, difficulty in treating diseases, satisfaction with medical personnel, and satisfaction with accessibility to medical facilities. The variables that significantly affected satisfaction with medical institutions were residence area, educational background, monthly health care expenditure, age, health status compared to the previous year, satisfaction with medical personnel, satisfaction with accessibility to medical facilities, primarily used medical institutions, number of visits to medical institutions, and difficulty in treating diseases. Based on the results, this study suggests policy alternatives tailored to consumers, specifically single-person elderly households in rural areas. These measures aim to improve access to medical institutions, reduce the burden of medical expenses, and enhance subjective health conditions.

This study utilized a qualitative case study approach to explore the essence and meaning of the experience of becoming parents, for parents with “early adolescent children” in the preadolescent phase. The study recruited three parents who had children ranging from 6th grade in elementary school to 2nd grade in middle school, all belonging to the early adolescent group of youth athletes, in a domestic setting. Semi-structured interviews were conducted with each participant three times, lasting for 1 to 2 hours per session, using an open-ended questionnaire. The data analysis of this study employed a multiple-case analysis method. This involved conducting within-case analysis to provide detailed descriptions and identify themes within each case, as well as conducting cross-case analysis to extract characteristics and themes across cases. As a result, ten subcategories and five core categories were identified. The core categories included ‘Career guide parents’, ‘Unified family, excluded siblings’, ‘Another family: distant yet close relationship’, ‘Role of a manager and role of a mom, dad’, and ‘Not in the role of a manager or parent, just myself’. This is expected to contribute foundational material for counseling and parent education targeting parents of youth athletes. This would provide valuable insights to such parents.

This study was conducted to examine the status of generalized anxiety disorder (GAD) among adolescents and its association with dietary behaviors, utilizing the raw data from the 17th Korea Youth Risk Behavior Survey (KYRBS). This study included 45,106 participants categorized into the low-risk (LRG, 88.3%) and high-risk (HRG, 11.7%) groups for GAD. The analysis of the effect of GAD on dietary behaviors revealed that in the HRG, there was a likelihood of consuming fast food (over 5 times/week), odds ratio (OR): 1.548 for males. Similarly, for females, there was a likelihood of consuming fast food (3-4 times/week), OR: 1.744 for females. For females, there was a decrease in the frequency of eating breakfast (0-2 times/week, OR: 1.109) and an increase in consuming sweetened beverages (over 5 times/week, OR: 1.433). While, in the analysis of the influence of dietary behaviors on GAD, it was found that in males, consuming sweetened beverages (over 5 times/week) increased the likelihood of being in the HRG, OR: 1.279. Additionally, the probability of being in the HRG increased gradually with the frequency of consumption of fast food (3-4 times/week, and over 5 times/week), with ORs 1.133 and 1.564, respectively. For females, the likelihood of being in the HRG increased by OR: 1.113 when having breakfast 0-2 times/week. Moreover, as the frequency of consuming sweetened beverages (over 5 times/week) and fast food (over 3-4 times/week) increased, the probability of being in the HRG also increased with ORs 1.436 and 1.745, respectively. This study confirms the association between GAD and dietary behaviors, suggesting that this should be incorporated into the appropriate procedures for the management of GAD.

This study compared the health behavior, nutrient, and food intake, nutrient density, and index of nutritional quality(INQ) in 2019 before the coronavirus disease-2019 (COVID-19) pandemic to that in 2020, after the start of the COVID-19 pandemic, in Korean elderly over 65 years of age. Data from the 8th Korea National Health and Nutrition Examination Survey (KNHANES) was used. The results showed that the average sleep time increased after compared to before the pandemic began. The frequency of eating out decreased, and the intake of vegetables increased while the intake of fish decreased after the pandemic began. Also, the intake of fiber, potassium, and vitamin B2 had increased since COVID-19 struck. An evaluation of the nutrient density and Index of Nutritional Quality (INQ) showed that the intake of vitamin B1 decreased while that of vitamin B2 increased in this period. It was found that elderly Koreans had an insufficient intake of vitamin A, vitamin C, niacin, and calcium regardless of the pandemic. Thus, this study revealed that the COVID-19 pandemic had little effect on the eating habits of Korean seniors. However, sleeping hours and the frequency of eating out were affected during the pandemic.

The purpose of this study was to compare the effects of two drying methods (hot air drying [HAD] or vacuum freeze drying [FAD]) on the physicochemical components and antioxidative activities of Aruncus dioicus var. kamtschaticus powder. The crude fat content in the FAD was higher than that in the HAD. There were no significant differences in the proximate compositions, such as contents of moisture, crude ash, crude protein, and carbohydrates, depending on the drying methods. The total amino acid and essential amino acid contents were significantly higher in FAD than in HAD. The valine, phenylalanine, lysine, histidine, aspartic acid, asparagine, glutamic acid, arginine, ornithine, and γ-amino-n-butyric acid (GABA) contents in FAD were higher than in HAD, while the serine, phosphoserine, proline, glycine, alanine, tyrosine, and taurine contents in HAD were higher than in FAD. There were no significant differences in saturated fatty acid, monounsaturated fatty acid, and polyunsaturated fatty acid contents based on the drying methods. The most abundant fatty acid in the FAD was linolenic acid, and the linolenic acid content was approximately the same, regardless of the drying method used. The contents of malic acid and total organic acids in the FAD were higher than in the HAD, while the content of succinic acid was higher in the HAD than in the FAD. Vitamin C and E contents in HAD were higher than those in FAD. The total polyphenol and total flavonoid contents, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino- bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activities of the FAD sample were higher than those of the HAD sample. These results indicate that vacuum freeze drying is a better drying method for preserving the nutritional components and antioxidative activities. These study results may provide the basic data for follow-up studies seeking a better understanding of the functional properties of the FAD powder.

The contents of malic acid and total organic acids in the FAD were higher than in the HAD, while the content of succinic acid was higher in the HAD than in the FAD. Vitamin C and E contents in HAD were higher than those in FAD. The total polyphenol and total flavonoid contents, the 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2-azino- bis-3-ethylbenzothiazoline-6-sulphonic acid (ABTS) radical scavenging activities of the FAD sample were higher than those of the HAD sample. These results indicate that vacuum freeze drying is a better drying method for preserving the nutritional components and antioxidative activities. These study results may provide the basic data for follow-up studies seeking a better understanding of the functional properties of the FAD powder.","PeriodicalId":477378,"journal":{"name":"Han-guk jiyeok sahoe saenghwal gwahak oeji","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135991246","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
