This study investigated on the nutritional components and physiological activity of four wild vegetables namely Salvia plebeia R. Br., Angelica acutiloba, Gynura procumbens and Saururus chinensis Baill for the development of representative wild vegetables in Chungbuk. Salvia plebeia possessed the highest radical scavenging activity and beta-carotene, but exhibited the lowest α-glucosidase inhibitory activity compared to the other three vegetables. Angelica acutiloba showed high crude protein content and α-glucosidase inhibitory activity, but contained low total polyphenol content, radical scavenging ability and beta-carotene compared to the other three vegetables. Gynura procumbens showed high mineral content, beta-carotene, vitamin K1 content and α-glucosidase inhibitory activity, but showed the lowest total polyphenol content and radical scavenging ability compared to the other three vegetables. Saururus chinensis showed high crude fiber content and total polyphenol content, but contained the lowest mineral and vitamin K1 content. To conclude, it is suggested to use Salvia plebeia or Saururus chinensis as antioxidant food materials and Angelica acutiloba and Gynura procumbens as food materials and sources of α-glucosidase inhibitors. In particular, it is believed that Saururus chinensis, which possessed high content of crude fiber, is suitable for low-calorie food materials such as diet products.

The purpose of this study was to investigate individuals' perceptions toward green tea and green tea cafes according to their usage of green tea cafes, gender, and marital status. The survey was conducted online and completed by 200 respondents who had been to green tea cafes and by 200 respondents who had not. The visitors of green tea cafes had more positive perceptions regarding the atmosphere, familiar taste, good quality of raw foods, freshness of foods, good service, excellent taste, and menu variety of green tea cafes. Males perceived green tea as 'good for health' more than the females. There was no difference in the perception of green tea cafes by marital status. Regarding a popularization plan for green tea cafes, the customers felt more need for a tea sommelier than the non-customers, and females versus males felt stronger about having a tea sommelier that would provide opportunities to taste various tea products and develop a green tea menu that considered nutrition and health. Unmarried respondents felt a greater necessity for having a place with a comfortable environment, tasting a variety of tea products, and having a chance to experience tea culture. When selecting a green tea cafe, the quality of the food and cleanliness of the cafe were considered to be most important. The implications of the data are discussed.

The digital environment has become an integral part of human lives today. This study aimed to investigate Mukbang watching status and its association with eating behaviors, eating habits, and the nutritional status of children. We conducted a survey of the actual status of Mukbang watching, and nutrition quotient of children (NQ-C) among 222 students in elementary schools in Daejeon. The prevalence of viewing Mukbang content was 68.9%, the most common frequency of viewing was 1~2 times per month (36.5%), and the duration of watching a single episode was less than 10 minutes (54.9%). Overall, 31.4% of students responded that they ate while watching a Mukbang and, 66.0% said they felt hungry after watching a Mukbang. YouTube (82.4%) was the most common source of viewing Mukbang. The most common reason for watching Mukbang was because all the students found the content entertaining. The NQ-C score of all the subjects surveyed was 58.95, which is a moderate grade. The scores of NQ-C, balance, and practice factors were significantly higher in boys than in girls. In addition, the scores of NQ-C, and balance and moderation were significantly higher in Mukbang non-viewers than viewers for all subjects and more specifically boys. These results suggest that watching Mukbang is associated with poor nutritional status in elementary school children. Therefore, it is necessary to consider the Mukbang watching status when providing nutrition guidance to instill healthy eating habits in children.

This study was performed to assess the perception and need for the elderly meal service program of the Korean elderly. The purpose of this study was to assess the dietary environment factors which are related to the perception and need for such service. Subjects of this study were 800 elderly persons of whom responses were received from 769(male: 26, female: 543) aged over 60 years. Their mean age was 7.51 $\pm$8.1 years. Seventy two point two percent of them lived with their family and 54.5% of them were supported economically by their children. Among their meal management behaviors, food purchasing was hard to perform and the most aid-needed activity. In their dietary environment, 47.1% of them were supported by their children. The percent of the subjects who were aware of the elderly meal service program was 48.4%. Men were more aware of the meal service program than women(p<0.01). Elderly who were supported by government were more aware of this service than others. Elderly who were in poor dietary environment, were less affluent or had trouble preparing meals expressed better perception this service than others (p<0.05). Those who requested meal services had poor dietary environment than those who did not (p<0.001). The elderly who were younger, with higher income, and lived with a spouse had more demand for home delivered meal service. This study showed that the poorer the greater desire for meal services. Therefore, the need for urgent improvement and expansion of meal services for elderly is suggested by this study.

In order to create a worker-friendly environment for institutional foodservice, facilities operating with a dry kitchen system have been recommended. This study was designed to compare the work safety and work environment of foodservice between wet and dry kitchen systems. Data were obtained using questionnaires with a target group of 303 staff at 57 foodservice operations. Dry kitchen facilities were constructed after 2006, which had a higher construction cost and more finishing floors with anti-slip tiles, and in which employees more wore non-slip footwear than wet kitchen (76.7%). The kitchen temperature and muscular pain were the most frequently reported employees' discomfort factors in the two systems, and, in the wet kitchen, "noise of kitchen" was also frequently reported as a discomfort. Dietitian and employees rated the less slippery and slip related incidents in dry kitchens than those of wet kitchen. Fryer area, ware-washing area, and plate waste table were the slippery areas and the causes were different between the functional areas. The risk for current leakage was rated significantly higher in wet kitchens by dietitians. In addition, the ware-washing area was found to be where employees felt the highest risk of electrical shock. Muscular pain (72.2%), arthritis (39.1%), hard-of-hearing (46.6%) and psychological stress (47.0%) were experienced by employees more than once a month, particularly in the wet kitchen. In conclusion, the dry kitchen system was found to be more efficient for food and work safety because of its superior design and well managed practices.

The purpose of this study was to identify the important contents from teachers’, parents’and students’view points based on the sixth Home Economics textbook contents, to apply these results at school settings and to provide the materials as a basis for the next curriculum revision. Subjects were 59 teachers, 253 parents, and 389 students from 3 cities and 5 counties in CholaBukDo. A questionnaire which was made by the researcher was used as an instrument for this study. The results are as follows： Of 32 contents on Family life subarea, all the teachers, the parents and the students put the emphasis on sex such as pregnancy, purity, sex-ethics, etc. This result means that middle-school students emphasized the sexual identity formation and this was also a common concern about adolescents in our society. Of 37 contents of Managing home resource and Consumer life subarea, teachers though the environment pollution is an important subject and parents and students thought finding a method to conserve good environment were more important. This result reflects their concern on the environment. Of 49 contents on Dietary life, teachers and parents emphasized “the importance of nutritive elements”which is basic on their dietary life and students were more interested in “adolescence and growth and development among adolescents’nutritional characteristics and problems”which is more related to their current life. Of 40 contents on Clothing life subarea, while teachers put the emphasis on the method how they can buy ready-made clothes, parents and students wanted them to teach what kind of clothes are suitable for themselves. Of 18 contents on Residing life subarea, teachers emphasized the importance of ventilation for adjusting the room environment and students were more interested in the effective use of the residing space. By finding out what kinds of Home-economics contents are important from the view point of teachers, parents and students, this study can be a useful resource for the next curriculum revision and for selecting contents of a new-coming text book. However, restricted sampling must be considered and further studies which cover the whole area might be needed.

This study aimed to investigate the effect on the chemical quality of whey and Ricotta obtained from ewes fed a red grape pomace (GP) dietary supplementation. The analyses were performed on whey, before and post Ricotta cheese-making, and in Ricotta after 1 (T1) and 5 (T5) d of ripening at 4℃. Moreover, fatty acid profile of whey before ricotta (WBR) cheese-making and Ricotta T1 of ripening and volatile profile of Ricotta T1 and T5 were investigated. The diet did not affect whey and Ricotta lipid content, conversely, significant variations were instead observed with regard to color. A lower amount of total phenolic compounds was found in WBR cheese-making, on the contrary, an opposite trend was highlighted in Ricotta T1 although no variations in antioxidant properties were detected. Moreover, GP modified fatty acid profile of whey and Ricotta but did not have any effect on protein profile of the main whey protein. The reduction of hexanal in Ricotta during the ripening suggest a better oxidative stability. The obtained results therefore suggested that the GP inclusion in the ewes diet, while modifying some chemical parameters, did not induce negative effects on the characteristics and quality of dairy by-products.

Background and objective: The purpose of this study is to analyze the case of healing experience for lifestyle and environmental diseases through life and activities in the forest from the perspecitive of critical realism, and how the causal power and mechanism of the healing experience relate to forest healing factors and programs. Methods: 93 video data of people who started living in the forest for disease treatment were analyzed using a qualitative content analysis method from the perspective of critical realism. Categories for analysis include general categories (age, duration, occupation, disease name), forest therapy categories (climate therapy, plant therapy, water therapy, diet therapy, kinesiotherapy, psychotherapy), and other categories (ecology, learning and management, life tools), etc., and the unit of analysis is the context unit. Results: 1) The diseases that motivated life in the forest were digestive system diseases, lung diseases, cardiovascular diseases, endocrine system diseases, and various lifestyle-related diseases and environmental diseases in similar proportions. This indicates that forest life does not have specificity to respond to specific diseases, but provides treatment and recovery for all lifestyle and environmental diseases. 2) Among the forest therapies, climate therapy and plant therapy are related to the climatic and residential environment in the forest where 'natural persons' live. And others such as water therapy, diet therapy, kinesiotherapy, psychotherapy indicate the change from the lifestyle that caused the disease to the lifestyle for treatment and recovery. Conclusion: Life and activities in the forest provide an environment for treatment and recovery in which the healing principles such as aromatherapy, nutritional and dietary therapy, kinesiotherapy, and emotional psychotherapy are integrated in the 'real world'.

A chronological account of the prospect and problems of utilization of urea in poultry diets is presented. Urea has long been considered as toxic to poultry but recent research, although limited, has yielded controversial results. The main problem appears to be due to the fact that whether or not response to urea is dependent on environment (germ free versus conventional). Although caecum is found to be the major site of ammonia production from urea, the so called nutritional benefit derived by chicken fed urea is probably limited to its utilization for the synthesis of nonessential amino acids in the protein depleted chicken, but not in the protein adequate chicken. More research is needed to monitor production characteristics of birds fed urea and investigate its toxic effect, if any, in some greater detail before recommending this nonprotein nitrogenous substance for inclusion in the poultry diets.
