This paper introduces a coordinated droop control for the stand-alone DC micro-grid, which is composed of photo-voltaic generator, wind power generator, engine generator, and battery storage with SOC (state of charge) management system. The operation of stand-alone DC micro-grid with the coordinated droop control was analyzed with computer simulation. Based on simulation results, a hardware simulator was built and tested to analyze the performance of proposed system. The developed simulation model and hardware simulator can be utilized to design the actual stand-alone DC micro-grid and to analyze its performance. The coordinated droop control can improve the reliability and efficiency of the stand-alone DC micro-grid.

This study was conducted to assess the recognition and consumption of meal alone and processed food according to major of college students in Seoul Metropolitan area and Chungcheong province, Republic of Korea. To accomplish this, a survey was conducted to investigate 353 college students (171 food & nutrition majors and 182 non-majors) regarding their general characteristics, dietary behaviors, meal alone issues, and the purchase and consumption of processed food. Most major and non-major students skipped breakfast. The main reason for skipping was not having time. Majors and non-majors put great importance on their lunch and evening meal, respectively. Nutrition information routes for majors were 'college class' (62.5%) and 'TV radio' (17.5%). However, the routes for non-majors to obtain nutrition information were 'internet smart phones' (41.1%) and 'TV radio' (28.3%). These results suggest the need to provide correct information concerning nutrition to college students. Most major and non-major students tend to have 0 to 2 times of meal alone per week. The main reason for meal alone was schedule unsuitable for eating with family or friends. The most critical factors for majors and non-majors when they chose menu to have meal alone were personal taste and money, respectively. The primary consideration for choosing processed food was price and the main purchase route was convenience store. The main reason for consuming processed food was easy-to-cook. Of processed foods, the most favored ones were noodles and fish products. Meal alone frequency was positively correlated with age (p<0.05), grade (p<0.05) and monthly allowance (p<0.05). Preference and consumption frequency of processed food were negatively correlated with concern about nutrition (p<0.05) and meal frequency (p<0.05), respectively. Based on these results, greater efforts should be made to provide meaningful information regarding programs for nutrition education to improve their dietary habits. Research and development of processed food specifically for college students eating alone should be increased.

This study examined the effects of eating alone, meal type, and dietary lifestyles on healthy eating capability of one-person households. We analyzed the mediation effects of weekly frequencies of each meal type taken by one-person households between eating habits such as eating alone and dietary lifestyles of one-person households and healthy eating capability. We also analyzed data from the 2019 Food Consumption Behavior Survey using a sample of 688 one-person households. Factor analysis, latent profile analysis, structural equation model analysis was conducted; direct and indirect effects of independent variables were tested using bootstrap method. The major results were as follows. Frequency of eating alone was about 10 times a week on average; one-person households had home-made meals about 12 times a week, for restaurant meals, 4 times, for delivered/take-out food, 0.39 times, and for other types, 0.44 times. Weekly frequencies of eating alone and meal types taken by one-person households were significantly different among the different socio-demographic groups. Dietary lifestyle was classified into four classes: traditional, health ignorant, food lifestyle ignorant, and balanced. Eating alone and dietary lifestyle had a significant effect on weekly frequency of each meal type. Frequencies of eating alone, balanced dietary lifestyle, and taking home-made meals had a positive direct effect on healthy eating capability, and frequency of taking delivered or take-out food and food consumption ignorant lifestyle had a negative direct effect. Eating alone, balanced and traditional dietary lifestyles had a positive indirect effect through the meal type; however, watching Mug-bang had a negative indirect effect.

Objectives: This study compared the dietary behaviors of single-person households when eating alone according to the employment pattern and age. Methods: A total of 566 people aged 20~59 years old were collected from the status of workers and classified into three groups according to their employment pattern (regular, non-regular workers and business owner). The subjects were collected by purposive quota sampling on a Gallup panel from June to November in 2017. The dietary behavior and perception of eating alone of the subjects were surveyed via online and self-reported questionnaires. Results: The frequency of eating alone was significantly higher in the regular group than the non-regular group and business group (p<0.01). The place of eating alone was significantly higher in the regular and non-regular group in the convenience store, and business group in the office (p<0.001). Ramen, the menu when eating alone, was significantly higher in the non-regular group than the other groups (p<0.01). The preference for eating alone was lower in the older age group (p<0.05). The young aged group (aged 20~30) ate more fast food and felt more convenience than the older aged group aged 40~50 years (p<0.05). Conclusions: Single-person households with a non-regular job have poorer dietary behavior in eating alone than those who had regular employment. In a situation of an increasing number of non-regular workers aged in their 20s and 30s, there is a high likelihood of social problems, such as health and poverty. This study highlights the need for a healthy food selection environment to improve the dietary life of single-person households with non-regular jobs for the diverse types of single-person households.
