The purpose of this study was to investigate the relationship between HMR use and eating habits in young Korean adults. This cross-sectional study was conducted on 575 adults (232 men, 343 women) in their 20s and 30s in Korea. Their use of HMRs (classified as ready-to-eat, ready-to-cook, and fresh convenience foods) and eating habits were surveyed. The main reasons for HMR use by men and women were convenience (54.7%, 64.4%) and promptness (24.2%, 24.2%), respectively. The most frequent place for HMR purchase was a convenience store (74.1% and 65.0%, respectively). Regarding the frequency of HMR use, 1~2 times a week was the highest for ready-to-eat (40.9%) and ready-to-cook (30.1%), while no eating was the highest for fresh convenience foods (41.0%). HMR preference was the highest (3.8 out of 5 on a 5-point scale) for ready-to-eat, followed by ready-to-cook (3.3 points) and fresh convenience foods (3.3 points). The use frequency and preference of total HMRs, ready-to-eat foods, and ready-to-eat foods were positively correlated with unfavorable eating habits, including unbalanced eating, overeating, salty eating, spicy eating, skipping, and irregular meals. However, fresh convenience foods showed negative correlations with unbalanced eating, overeating, and salty eating. The use frequency and preference of total HMRs, ready-to-eat foods, and ready-to-cook foods were positively correlated with undesirable eating habits. However, fresh convenience food showed a negative correlation with eating habits such as unbalanced, overeating, and salty eating. These results should be considered for favorable food production and consumer guidance to promote healthy food choices.

In Korea, traditional doenjang is manufactured using the conventional method at home and by small-scale enterprises. Because this age-old process depends on natural inoculation of various microorganisms, it is difficult to reproduce or maintain consistency in the final product quality across batches. Moreover, doenjang occasionally prepared by this method raises safety concerns related to aflatoxin, biogenic amine, and Bacillus cereus contamination. To develop starters that can be conveniently used at home or in small industry settings for the manufacturing of safe and flavor-improved doenjang, autochthonous microbe starters were developed in dried forms as ready-to-use starters. Each starter powder prepared by heat- or freeze-drying methods remained stable even after 24-week storage. These ready- to-use starter powders were successfully applied to lab-scale fermentation for the production of safe and flavor-improved doenjang. We believe that these ready-to-use starter powders will benefit small-scale enterprises in the manufacturing of doenjang of good reproducible quality.

Objectives: The rise of one-person households may have consequences for food consumption patterns, and eating habits. This study investigated the home meal replacement (HMR) use and eating habits among adults in their 20s-30s living in one-person households. Methods: A total of 247 adults aged 26-39 years participated in this study. The subjects were divided into three group according to the household type; one-person households (n=80), two-person households (n=49), and multi-family (three and more members) households (n=118). Their use of HMRs (classified as ready-to-eat, ready-to-cook, and fresh convenience foods) and their eating habits were all compared. Results: The mean age of the subjects was 30.5 years, 47.8% were male, and there was no significant difference in age, gender, occupation, and monthly income according to the type of household. The intake frequency of total HMR and ready-to-eat foods was significantly higher in one-person households among the three groups. People in one-person households consumed more HMRs alone, and spent more money to buy HMRs. Undesirable dietary habit scores like unbalanced eating (p<0.05) and eating salty foods (p<0.05) were significantly higher in the one-person households. Among the total subjects, the unbalanced eating scores showed a significant positive correlation with the intake frequency of ready-to-eat foods, while the unbalanced eating scores showed negative correlation with the preference of fresh convenience foods. The scores for eating salty foods showed a significant positive correlation with the intake frequency and preference of ready-to-eat foods and ready-to-cook foods, while there was negative correlation with the intake frequency and preference of fresh convenience foods. Conclusions: Adults in their 20s-30s in one-person households consumed more ready-to-eat foods than those in multi-family households. In addition, people with one-person households had more unbalanced diets and ate more salty foods, and these undesirable eating habits showed a significant positive correlation with the use of ready-to-eat or ready-to-cook foods. These results should be addressed for producing healthier ready-to-eat/ready-to-cook foods and implementing nutrition education for making healthy food choices of one-person households, which are steadily increasing.

The purpose of this study was to analyse factors related to Home Meal Replacement (HMR) use among university students and to determine the dietary quality according to its consumption. A survey on the consumption of HMR and Nutrition Quotient (NQ) was conducted from September to November 2021. The study included 232 university students (88 males, 144 females) from Chungcheong. The proportion of consumption at least once a week was 71.55% for ready-to-eat foods, 55.60% for ready-to-cook foods, 40.95% for fresh-cut products, and 21.12% for meal-kits. The preference ratings were as follows: ready-to-eat foods, 3.77 out of 5 points, meal-kits, 3.53 points, fresh-cut products, 3.52 points, and ready-to-cook foods, 3.45 points. In terms of satisfaction, convenience (4.06 out of 5 points), taste (3.71 points), variety (3.67 points), and food hygiene (3.62 points) were rated the highest. The scores in the moderation NQ were significantly lower in the groups that consumed ready-to-eat foods (p=0.0002), ready-to-cook foods (p=0.0002), and meal-kits (p=0.0068) at least once a week compared to the groups that consumed them less than once a week. In conclusion, the results will serve as basic data for nutrition education for proper consumption of HMR among university students.

In the manufacturing process of ready-mixed concrete, quantity management directly affects the workability and strength of concrete. Therefore, water quantity is the most important management factor for water quality control of ready-mixed concrete. It can be said that the number of unit water in the mix design, the water quantity due to the surface water contained in the aggregate used, and the water quantity taking into account the concentration of sludge contained in the recycling water when using the recycling water are factors that affect the quantity management of ready-mixed concrete. In this study, as a stable quality control method of ready-mixed concrete, a quantity management method by aggregate surface water and a sludge concentration management method according to the use of recycling water were proposed. Thus, we tried to suggest an efficient quantity management method for stabilizing the quality of ready-mixed concrete.

The purpose of this study is to analyze the actual condition and problems of current ready-made shrouds. Current shrouds were formed after the 20th century and therefore are quite apart from its traditional precedents of Chosun Dynasty. In this respect, several problems can be pointed out. 1. The use of natural colored hemp as a primary textile of current shrouds is far from our tradition. Silk, ramie, and cotton have to be used together with hemp. Also, more variety of colors can be used other than natural white. 2. The size of ready-made shrouds has to be categorized at least into three: large, medium and small 3. The pattern and sowing method of Dopo(도포) and Wonsam(원삼) should be corrected in line with those of the traditional Dopo(도포) and Wonsam(원삼). 4. The design and items of current ready-made shrouds have to break away from the standardized convention and should seek more of a variety that our rich tradition provide. 5. The rational index should be suggested so that consumers can compared the quality and price of ready-made shrouds available at their hands.

Increasing use of plastics in food packaging materials has led to the issue of food-plastic packaging materials mutual interactions. Rapid development of new microwavable ready-to-meal products requires suitable plastic packaging materials for safe heating with the contained food. However, data is still required to diminish consumers' safety concern about ready to meal packaging materials. Amounts and patterns of extracted materials from the ready-to-meal packaging materials of Korea and Japan by heat treatments ($120^{\circ}C$ for 30 min.) was investigated and compared by using Gas chromatography. Total peak number of extracted materials from Korea packaging materials was six while that of extracted materials from Japan's was only two. Moreover, the extracted amounts of packaging materials from Korea company was much higher than those of Japan's. Additional research is needed to justify the reason why extracted materials from packaging materials from Korea be much more occurred, and how the amounts from Korea packaging materials can be reduced.

Recent advances in augmented reality (AR) and virtual reality (VR) technologies have led to a significant increase in metaverse platforms. Metaverses are setting a new direction for the digital world. This paper examines the phenomenon of virtual worlds that are becoming an issue these days, focusing on [Ready Player One]. One of the common features of the metaverse platform in [Ready Player One] and the platforms currently in use is the concept of open world. This is a feature that goes beyond simply moving around in a virtual world and allows users to freely reset, participate in, and control the environment. This innovative concept is a hallmark of metaverse platforms, and it is becoming increasingly important and influential. Through this study, we focused on the [open world system] of the platform in the movie and the modern metaverse platform, and suggested and studied how the scalability of the metaverse will present a turning point in the future.
