This study is aimed at developing a nutritional task of a community' as a public health activities of Su-Dong Myun, Demonstration Project area of Ewha Womans University. The content of this study is the points of nutritional diagnosis for the residents nutritional evaluation, the analysis of the related factors and the educational material with Nutrition Education-Index. Two hundreds housewives were examined during the period of Jan. 20 to Jan. 30 in 1989. 1. In terms of the housewives' age, those aged 30 to 39 were 32.5% which was the highest and educational level, graduation of primary school was 31.5% which was the highest. The housewives who had no job were 60.0% and those who participated in community activities were 56.5%. 2. In terms of the points of nutritional diagnosis, 50 to 74 points were 51.5% which was the highest and total average was $65.1{\pm}15.0$. 3. As for the points of nutritional knowledge, the average was 54.9 points, attitude was 77.4 points and eating practice was 70.8points. 4. The number of clinical symptoms of nutritional deficiency was 16.1 ones per person. 5. As for the relation which nutritional knowledge, attitude, eating practice exert on one another, nutritional knowledge has negative correlation with eating practice(-0.04) and attitude has some correlation with eating practice(0.17). 6. The variable having to do with the points of nutritional diagnosis showed the highest correlation coefficient(0.55) as the points of nutritional knowledge. 7 As for the variable having to do with the number of the symptoms of nutritional deficiency, the higher points of knowledge(-0.05) is, the higher the totai averse points of nutritional diagnisis(-0.09) is, negative correlation was appeared. 8. The result in which the variant having to do with the number of clinical symptoms of nutritional deficiency was analyzed by multiple regression analysis showed that the lack of time for preparing meals in non agricultural households made the greatest contribution (9% explained) and the households having vegetable garden made the second greatest contribution(3% explained).

Objectives: The purpose of this study was to compare the first echo boomer to second in the needs for family strengths and family functions, after controlling the sociodemographic characteristics. Method: For this study, a survey was conducted with 406 never-married young adults, which has 182 first echo boomers and 224 seconds echo boomers as using the same self-report questionnaire. Results: First, the two echo boomer groups exhibited similar patterns in their perception of the three family strengths, positive family values, pursuit of coexistence, and spiritual value, in that order. On the other hand, in regard to family functions, groups' perceived emotion entertainment leisure function as core functions of the family, but the second echo boomers, unlike the first echo boomers, expressed a higher need for economic functions rather than functions for children generation. Second, the analysis of this study indicated that, even in cases where first and second echo boomers had the same social-demographic characteristics, the latter in contrast with the former tended not to regard spiritual values such love for shared ethical values, compassion, and religious beliefs as a family strength, and did not require functions for children generation of the family. Conclusions: From these findings, the differences in the needs for family strengths and functions expressed by the two generations belonging to two different birth cohorts were influenced by various changes in Korean society occurring between the two generations, such as the social divergence in the functions of care and nurture, the increase in one-person and childless households, and the weakening of kinship-centered or communitarian forms of familism.

The West Coast is known as one of the world's three largest intertidal mudflats but the mudflat ecosystems have been constantly destroyed by various reclamation projects and industrial complexes. This study intends to estimate the economic values of major ecosystem services provided by the Seocheon intertidal flats using a choice modeling method. The benefits of the intertidal flats are categorized as four different attributes: number of migratory birds (related to biodiversity and cultural services), production of fish and shellfish (regulating services and habitats), tourism activities (cultural services), and number of fishing households in local communities (cultural services). Study results show that the general public enjoys the economic benefits of 1.777 trillion won (900 million won/hectare) as of 2015 in order to preserve 1,200ha of Seocheon mudflat. Assuming that future generations continue to enjoy these economic benefits of mudflat conservation, the annual value converted is about 64.7 billion won/year, corresponding to 53.9 million won/hectare per year. Individuals are willing to pay are expected to maintain their entire life in the 1,000 households living in the Seocheon tidal-flat fishing village, with an average of 11,000 won per person and an additional 50,000 tourist activities per year. It was estimated to have the amount of payment of 9,000 won. An individual's marginal willingness to pay was estimated to be about 11,000 won per year for supporting a total of 1,000 fishing households, 6,000 won to provide tourism activities of 50,000 visitors, and 9,000 won to provide the habitats of 90,000 migratory birds. For segmentation analysis, residents of Seocheon did not place significant values for the attributes besides migratory bird conservation. However, those of Gunsan showed relatively low margtinal willingness to pay for conservation of migratory birds and fishing villages but showed similar preferences for the maintenance of tourism activities compared to the general public. The results imply that the introduction of economic incentive system is needed to effectively manage and conserve ecosystem services of specific intertidal flats.

As single-person households increase, demands for self interior design has been also increasing. The furniture arrangement takes big part of interior design. But sometimes people need professional helps for the proper and effective arrangement of furniture which makes self-interior design harder. Often, people share information and advices about interior design through Social Network Service. Experts could help directly but this approach would have several issues: First, the detailed and accurate advice would be difficult because experts have to examine the space through 2D pictures or video. Second, they have to make an appointment which would cause inconvenience to both customer and expert. In this paper, the furniture arrangement application for real-time sharing of interior design based on virtual reality is proposed to make up for the weak points. People can precisely share information and advice about self-interior design through this application in realtime, reducing waste of time and energy.

This study investigated the effects of self-esteem on the depression of baby boomer and eco-boomer generation (the children of baby boomers) living alone. It was identified from the point of view of comparison between the two groups. Using the 15th data of the 2020 Korea Welfare Panel, an independent sample t-test and hierarchical regression analysis were conducted with the data of baby boomers who live alone (born in 1955-1963) and eco-boomers who live alone (born in 1979-1992). The results of this study show that baby boomers who live alone had lower levels of education, income, and health condition than the eco-boomers who live alone, and had higher level of depression, but relatively lower level of self-esteem. In both groups, self-esteem had an effect on depression, but it was confirmed that the influence was greater in the group of baby boomers (Adjusted R2 .259) than in eco-boomers (Adjusted R2 .083). Based on the results of this study, practical and policy alternatives were suggested to prevent the depression among middle-aged, elderly people, and young adults who live alone.

People who spend more time alone tend to report higher levels of loneliness. However, whether people experience loneliness in solitude can differ The current research investigated the role of a sense of power as a predictor of loneliness among people who lack social interaction. investigated factors predicting loneliness in people with little social time large-scale survey data. As a result of discriminant analysis, a sense of power was verified as a factor that lonely non-lonely groups. a sense of power As a result, a causal relationship between a sense of power and social loneliness was confirmed. When people feel alone, a high sense of power can work as a buffer against loss of belongingness and the experience of social loneliness. This research focused on psychological rather than situational factors to alleviate loneliness in the current situation where social encounters are limited due to the increase of single-person households and the 19 pandemic.

The officetel introduced into Korea in the mid-1980s has thus far been in the limelight as the object of investment for the substitute for small-sized housing and for lease income. But to raise the possibility of succeeding in officetel investment in the future, it has been necessary to make a systematic analysis of the changed direction of the officetel market and the profitability and stability of investment. Accordingly, this study attempted to analyze demand for officetel with a focus on the possibility of increase in the households composed of one or two members, the major consuming bracket of small-sized housing. And it attempted to analyze the possibility of investment in officetel as the investment goods for lease income due to the entry of Korea into aging society. And past analysis of investment in officetel was confined to profitability analysis, but this study sought to develop the stability indicator of the officetel for the analytical purpose. As a result, it is predicted that demand for small-sized housing will increase due to the increase in 1-to 2-person households. Accordingly, it is predicted that demand for officetel as the place of residence will come to increase. And taking into consideration the more serious degree of sustained aging in the population, older people's preference for real estate and need for lease income, it is predicted that preference for officetel as the object of investment will increase. An attempt was made to analyze the profitability and stability of investment in the metropolitan area which the officetel has principally been supplied, in order to analyze the profitability and stability of officetels. For the purpose of this study, Yeoksam-dong in Kangnam-gu, Yeoui-dong in Youngdeungpo-gu, Bongcheon-dong in Kwanak-gu were selected in Seoul as the area for analysis. Jung-dong in Wonmi-gu, Bucheon, Seohyun-dong in Bundang-gu, Seongnam, Janghang-dong in Ilsan-gu, Koyang were selected in Kyonggi province as the area for analysis. As a result, it was found that the small-sized officetel had higher profitability and stability than the large-sized officetel. It was found that the area of Kyonggi Province had the larger deviation by size. That is, it was found that the small-sized officetel in the area of Kyonggi Province was significant as the object of investment for stable lease income.

This study aims to review the trends of the population outflows in the metropolitan area of Busan and to investigate the factors that affect population out-migration to the Seoul metropolitan area. The following variables are considered for analysis: traditional population movement variables and quality of life variables, such as population, society, employment, housing, culture, safety, medical care, greenery, education, and childcare. The 'domestic population movement data', provided by the MDIS of the National Statistical Office, was used for this research. Out of the total of 57 million population movement data in the period 2012 - 2017, population outmigration from Busan to the Seoul metropolitan area was extracted. Independent variables were drawn from public data sources in accordance with the temporal and spatial settings of the study. The multiple linear regression model was specified based on the dataset, and the fit of the model was measured by the p-value, and the values of Adjusted R2, Durbin-Watson analysis, and F-statistics. The results of the analysis showed that the variables that have a significant effect on population movement from Busan to the Seoul metropolitan area were as follows: 'single-person households', 'the elderly population', 'the total birth rate', 'the number of companies', 'the number of employees', 'the housing sales price index', 'cultural facilities', and 'the number of students per teacher'. More positive (+) influences of the population out-movement were observed in areas with higher numbers of single-person households, lowers proportions of the elderly, lower numbers of businesses, higher numbers of employees, higher numbers of housing sales, lower numbers of cultural facilities, and lower numbers of students. The findings suggest that policies should enhance the environments such as quality jobs, culture, and welfare that can retain young people within Busan. Improvements in the quality of life and job creation are critical factors that can mitigate the outflows of the Busan residents to the Seoul metropolitan area.

Recently, the proportion of housing lease has been increasing to an overwhelming level in line with the increase of single-person households and the change in the form of housing. In the normal case, the use of rental-type housing is subject to a housing lease agreement through a licensed real estate agent. In the event of a transaction conclusion, licensed real estate agent shall issue a contract containing the personal information of the lessee, the renter, and the licensed real estate agent to the transaction party. In this case, it is necessary for the lessee to provide the contract to a third party. This paper analyzes relevant laws and regulations and the status of housing transactions, focusing on personal information processed between offline housing lease agreements. And when issuing a contract through IRTS, we propose a way to protect personal information by providing a third party in three forms: information Data Subject-based, Purpose of usage-based De-identification, and Certificate of Contract.

General purpose of the study was to understend nutritional status of the Korean farmers and thus provide rural nutrition intervention programs with more useful in formation and data. The data for the study was collected two times from the 603 sample farm households in 1982 and 1987. The main results of the study were as follows ; 1) Food intake of the Korean farmers was highly dependent upon vegetable foods especially on cereals and gains. However the unbalanced food intake pattern was gradually improved as consumption of vegetable foods was decreased from 992.8 grams per person per day in 1982 to 946.4g in 1987 and that of animal foods increased from 54.2g to 91.4g . 2) In mean value analysis on nutrient intake of the farmeres intakes of energy and protein were nearly reached to Recommended Dietary Allowances(RDA) level; intakes of calcium vitamin A and riboflavin were quite deficient whereas iron thiamin niacin and ascorbic acid were well over. From 1982 to 1987 intakes of all nutrients except energy were increased. 3) In distribution analysis on nutrient intake coefficient of variation(CV) of all nutrients except iron was increased. skewness(SK) the coefficients of calcium iron vitamin A riboflavin and ascorbic acid were decreased Kurtosis (Ku) of iron and vitamin A was increased. On the whole distributions of nutrient intake of the farmers were changed in undesirable ways although the mean values of the nutrient intake were improved 4) In relationship analysis among 115 relationships 76 relationships were consistent between 1982 and 1987. Of 76 consistent relationships only 10 relationship were significant at 5% level such as the protein intake level and the balance of food intake calcium intake level and the age etc.
