Objectives: Driven by a growth of single-person households and individualized lifestyles, solo dining in restaurants is an increasingly recognizable trend. However, a research gap exists in the comparison of solo and group diners' menu-decision making processes. Based on the self-control dilemma and the temporal construal theory as a theoretical framework, this study compared the ordering intentions of solo vs. group diners with healthy vs. indulgent (less healthy) entrées. The mediating role of consumption orientation and the moderating role of amount of menu nutrition information were further explored to understand the mechanism and a boundary condition. Methods: A scenario-based online survey was developed using a 2 (dining social context: solo vs. with others) × 3 (amount of menu nutrition information: no nutrition information vs. calories vs. calories/fat/sodium), between-subjects, experimental design. Consumers' level of nutrition involvement was controlled. A nationwide survey data (n = 224) were collected from a crowdsourcing platform in the U.S. Data were analyzed using multivariate analysis of covariance, independent t-test, univariate analysis of covariance, and moderated mediation analyses. Results: Findings reveal that solo (vs. group) diners have less (vs. more) intentions to order indulgent menu items due to a more utilitarian (vs. more hedonic) consumption orientation in restaurant dining. Findings also show that solo (vs. group) diners have more (vs. less) intentions to order healthy menu items when the restaurant menu presented nutrition information including calories, fat, and sodium. Conclusions: The findings contribute to the literature of foodservice management, healthy eating, and consumer behavior by revealing a mechanism and an external stimuli of solo vs. group diners' healthy menu-decision making process in restaurants. Furthermore, the findings provide restauranteurs and health professionals with insights into the positive and negative impacts of menu nutrition labelling on consumers' menu-decisions.

This study analyzed the comparative importance of the selection of a restaurant for solo diners, and suggests a solution for the ideal type of the restaurant that are appealing to solo diners using conjoint analysis techniques. A total of 280 questionnaires were distributed to consumers who had experience dining alone from June $7^{th}$, 2017 to June $14^{th}$, 2017, and 261 were completed (93.21%). As a result, the importance of the attributes of the restaurant was found to be the menu for solo diners (36.92%), price (30.29%), seating for solo diners (20.87%), and serving time of food (11.91%). The ideal combination of selection attributes was found to be having a menu for a solo diner, having a seat for a solo diner, meal service time of less than 10 minutes, and a low price of 2,500won. These results will form a database that contributes to the development of differentiated products and is building marketing strategies that can satisfy the needs of solo diners.

In order to investigate the differences in nutrient intakes and eating habits between people living alone and people living together with family or others by age group, dietary survey data of the subjects aged 20 years or older from 2001 Korean National Health and Nutrition Survey were analyzed. Living status of the subjects was defined as 'single' when the subjects' household member was one person. Age, gender, income, education were adjusted during the comparative analysis. The subjects living alone had diets with lower score of nutritional adequacy ratio and lower quality, and drank more alcoholic beverages when compared with the subjects living together. Females were more greatly affected in dietary intakes by living alone situation than males. Of the four age groups, a group with ages from 30 to 39 years showed less nutrient intake patterns in persons living alone than in persons living together, but the rest three groups with ages from 20 to 29, from 50 to 64, and 65 or older did not show any significant differences. Eating habits of the subjects living alone, such as skipping meals, kinds of snacks, dining-out, were worse as a whole than the other. In conclusion, single living particularly of females or of 30 to 39 years of age group had negative influences on dietary intakes and behavior. There may be statistical errors if socioeconomic and demographic factors such as age, gender, income, and education are not controlled in the population study investigating the effect of living alone on dietary intakes. Further studies will be needed to know the age-specific reasons for the worse nutrient intakes of single living persons.

The aim of this study was to investigate the effects of household type on the health- and food-related behavior of the elderly. The survey was conducted on 304 free-living elderly persons in Chun-Chon city in 1999. The subjects were divided into three groups by their household types : living alone (n=35), living with their spouses (n=59), and living with their extended family (n=191). The results were obtained by personal interviews using questionnaires. Compared to the group living with their spouses and/or extended families, the elderly living alone were : less satisfied with the amount of monthly pocket money available; less involved in social activities; taking less vitamin supplements; doing less physical exercise; more frequently skipping meals and dining out; less frequently consuming meats, vegetables, fruits and seaweed; and having the highest rate of depression. The elderly living with their spouses tended to have the best physical functions and the greatest ability to carry out basic daily activities. The elderly living with their extended families had a higher incidence of diseases compared to the other groups. The preferred snacks were cookies for the elderly living alone, and fruits for the other two groups. In summary, it has been shown that household type should be taken into consideration for formulating adequate future strategies for effective health and nutrition programs.

The current socioeconomic climate has meant more children spend more time alone at home even for dining. This study was performed to characterize modem Korean childrens´food ecology based on mealtime atmosphere. A total of 705 elementary school students, 347 girls and 358 boys took part in the study. They were chosen evenly from the Seoul metropolitan areas, provincial cities, or rural areas, and were asked to fill out a questionnaire. The questionnaire was categorized to determine various factors related to food ecology, life styles, and health related symptoms. The average age of the study subjects was 11.5 years. The average height, weight, body mass index, and Rohrer index were 143.2cm, 37.6kg, 18.2 and 127.2 respectively. A significant number of children(39.2%) answered their bed time was between 11 and 12 pm. Only 28.3% answered that the whole family has breakfast together, and 47.7% have dinner together. A considerable number of children, 17.8% for breakfast and 6.9% for dinner, answered they eat alone. Most of the children answered they like to have dinner with the whole family. Half of the children answered they do not feel hungry before having breakfast. Proportions of children for their favorite meal time were 66.8%, and 25.4% and 7.8% for dinner, school lunch, and breakfast respectively. The largest proportions of children, 53.3% and 68.7%, have breakfast and dinner at home. Most of the children(75.2%) never purchase their dinner. Forty two% of the children answered they like school lunch, however, 60% of children answered they leave portions of lunch uneaten occasionally or always. Only 38.0% and 46.2% of the children have nutritionally adequate diet for breakfast and dinner. Children having more meals with the whole family possessed a more positive attitude towards breakfast compared to the children who eat with the whole family less frequently. In conclusion, Korea children are exposed to different health threatening food ecology problems related to changing environments, and consistent concern and support from community nutritionists are required.

The aim of this paper is to find out different preference of common spaces and shared activities in senior cohousing community between regions in Korea: Seoul and other cities. Social survey was conducted nationwide and the respondents were 50s only, since they are the generation who will face to elderly housing subject within 10 years in turbulent Korean society. Collected data, about 1000, were analyzed by SPSS program using frequency, percentage, and Chi-square test. In summary, respondents mostly would like to move to senior cohousing on circumstance when they remain alone without big difference between regions. Loneliness and housekeeping were considered as the most difficult issues for the elderly to manage by themselves. Among common spaces, exercise room was the most preferred space to meeting room and kitchen. Exercise room was more preferred in Seoul than in other cities, on the contrary meeting room was evidently less preferred in other cities than in Seoul. Regarding shared activities, resident meeting, gardening, and common meal were revealed as less preferred activities than hobby exercise and tea meeting. As a conclusion, I would like to propose that a big common living room is better to be designed for meeting room cum dining and gathering room with flexibility in order to give residents chances to know each other more often. And since common space and shared activity show different preferences by regions, those are to be designed and planned reflecting region's different circumstance.

The purpose of this study is to clarify the spatial changes that have taken place in the main rooms (Anbang) and kitchens of traditional Utbangkkeokeum houses in Cheongju city, located on the central inland of Korea. These houses consist of a main house (Momchae) and a single-wing house (Nalgaechae), creating an ㄱ-shaped plan. The kitchen is in the front of the Nalgaechae, and the Anbang is at the rear. For the Momchae, the main hall (Daechung) is next to the Anbang, which is at the end of the Nalgaechae, and the room (Gunnunbang) is situated across from the Daechung. This study is based on the assumption that these houses have been conserved and altered from their original forms. As a result of alterations, many changes have occurred to the main room and kitchen spaces. The traditional main room is connected with two rooms (Utbang and Araebang), new standup kitchens are introduced, and floor heating systems are installed. The Anbang has maintained its sedentary lifestyle and the space for major daily activities such as sleeping and TV viewing. Also, TV viewing is a distinctive feature for residential purposes and the bedding is located in such a position that it is easy to observe any exterior movement for the elderly living alone. The layout of the standup kitchen has been altered to maintain the previous circulation, position and function of the entrance. Also, the kitchen and dining room were used together, and the size of these rooms has been partially increased from the original module in different ways for each case. The above findings suggest that Utbangkkeokeum houses of Cheongju city have been spatially changed while maintaining the previous lifestyle.

Considering that the number of middle-aged single-person households is increasing, this study investigates dietary behaviors, nutrient intake, and mental health according to household type. Data were procured from the 2015-2019 Korea National Health and Nutrition Examination Survey (KNHANES). Totally, 5,466 participants aged 50-64 years were classified into 2 groups: a household with one member was defined as a single-person household, and households with two or more members were described as multi-person households. Single-person households comprised 10.63% of the total, with a higher average age, and lower income and economic levels than multi-person households. Compared to multi-person households, single-person households had a higher frequency of skipping breakfast, eating alone, and dining out, the moderately and severely food insecure group was more than 5 times, and nutrient intake and dietary quality were poorer. In the fully adjusted model, the odds ratios (ORs) of depressive symptoms were 2.35 times (95% CI: 1.39-3.96), and suicide ideation was 1.95 times (95% CI: 1.35-2.82) in single-person compared to multi-person households. Our results lead us to conclude that poor dietary intake in middle-aged single-person households affects the mental health, and the above factors should be considered when framing the dietary policy.

The purpose of this study is to search how to promote health and improve nutrition and health care of the elderly people in rural area. Behaviors for health promotion and habits against health risk were surveyed. Dietary management was analyzed for surveyed nutrient intake by 24 hr -recall method. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire for health behavior and dietary management was carried out by trained interviewers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Characteristics of the elderly people were 61-74 year-olds (68.2%), elementary school educated (78.4%), with spouse (51.7%), monthly living cost of 500-1,000 thousand won(43.4%), and monthly pocket money of 50-100 or 100-200 thousand won(33.5%, 26.5%). 41.4% of the subjects checked up medical examination regularly. The alcohol drinking status was significantly different according to gender: high no-drink rate of female (52.5%) and low no-drink rate of male (25.6%). Kinds of disease were different according to gender: higher proportion of cardiovascular disease(46.3%) and diabetes mellitus(8.1 %) in male and joint lumbago neuralgia(44.4%) and osteoporosis(8.6%) in female. Gastrointestinal complaints were nausea (69.0%) and chronic indigestion (17.8%). Constipation (12.0%) and vomiting (4.3%) were more frequent in female. Dietary management was good (3 meals per day: 93.4%., dining with family: 72.4%, regular mealtime: 72.4%, and 3-4 times of snacks per week: 44.9%) except side dish taking of 3-4 kinds only. However, almost one-third of the female elderly ate alone (30.6%) which was well compared with one-fifth of the male (19.7%). And food and nutrients intake were not significantly different according to gender except that male elderly's intake of energy and protein was lower than that of female's. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some female elderly had some difficulties with Instrumental Activities of Daily Living (IADL) like working at home, using transport, and going shopping. These results suggest that low quality of life linked with low economic status of the rural elderly and that congregate meal at village hall would be required for the female elderly eating alone. For the undernourished male elderly, it would be needed to provide snacks and to establish nutrition and health surveillance system.
