Recently, the rapid increase in vacant houses in urban areas has caused various problems such as worsening urban landscape, causing safety accidents, crime accidents, and hygiene problems. According to the Statistics Korea Future Population Estimation results, the growth rate of Korean population and households is expected to continue to decrease, which is likely to lead to an increase in the occurrence of vacant houses. If the problem caused by the occurrence of vacant houses is neglected, it causes not only a physical decline such as a deterioration of the residential environment but also a social and economic decline. In order to solve this problem, it is necessary to grasp the spatial distribution characteristics of vacant houses at the local level considering the existence of regional characteristics and spatial influence. Therefore, in this study, in order to measure global spatial autocorrelation, the analysis was conducted centering on the old downtown area of Busan, where there are many vacant houses through Moran's I and Geographically Weighted Regression(GWR). In addition, the distribution of vacant houses in different spatial units in Eup_Myeon_Dong and Census was analyzed to evaluate the possibility of Modifiable Areal Unit Problem(MAUP), which differ in the results of spatial analysis as the spatial analysis units change. As a result of the analysis, the occurrence of vacant houses by Eup_Myeon_Dong in the old downtown area of Busan had spatial heterogeneity, and the spatial analysis results of vacant houses were different as the spatial analysis units were different. Accordingly, in order to understand the exact distribution characteristics of vacant house occurrence, spatial dimensions using the GWR model should be considered, and it is suggested that consideration of the MAUP is necessary.

The research was performed responding to the growing needs of Korean foster care programs. It deals specifically with the people who voluntarily provide foster care despite the lack of Government support. The research has also made an effort to understand how the foster parents perceive their parent roles for the foster children. According to the research results based on the parents from the H foster care center, it showed that foster parents generally come from higher educational backgrounds compared to their equivalent age group and also similar or even higher income levels than the average family residing in an urban area. Conclusively, their traits in socio-demographic factors is said to be homogeneous. The research also focused on examining the role perceptions of Korean foster parents. The foster parents were well aware and educated on the significance of the children's psychological adjustments. However, the research recognized some role responsibilities that the parents failed to understand. Hopefully the foster care centers will take on such responsibilities and contribute in helping the parents realize their insufficiencies. Based on the results of the research, the researcher was able to recognize the important issues involved in the recruitment, selection, and education process for the foster parents. Additionally, new role adjustments are necessary among both foster parents and foster centers.

This study conducted oral examinations and individual interviews on migrant multi-cultural family women in Daegu and measured their socio-demographic characters, oral health conditions and OHIP-14 in an aim to investigate the relevance between the oral health of migrant multi-cultural family women living in some big cities and their quality of life. Based on data finally collected from 189 women, the t-test, ANOVA and binary logistic regression analysis were conducted and the conclusions are as follows: The average number of decayed teeth was 2.23, loss teeth was 1.48, and treated teeth was 5.58. Women from the Philippines had more number of loss teeth than those from other countries, and women from China relatively had a small number of filled permanent teeth. The quality of life related to oral health was found to be poor in proportion to the number of loss teeth. A comparison of life quality related to oral health depending on loss teeth showed that life quality related to oral health was lowest in the areas of mental discomfort, physical ability decrease, mental ability decrease, social ability decrease and social disadvantage. Life quality related to oral health was found to be low in proportion to the number of permanent teeth with decay experience and poor monthly household income, which shows that the number of permanent teeth with decay experience and monthly income are mostly related to life quality related to oral health. As migrant multi-cultural family women's life quality related to oral health is low in proportion to the number of loss teeth and decayed teeth, it needs to develop a program to improve their oral healthrelated life quality and conduct follow-up research to verify its effect.

The purpose of this study is to explore the effects of the middle aged's perception of successful aging on their preparations for the old age. We used data from 350 participants, aged 35-64 in Seoul-Gyonggi region. The hierachial regression analysis estimated the relation between the middle aged's perception on successful aging and their preparations for the old age. The findings indicate that the middle aged's level of preparations for the old age was slightly higher than average. The level of their emotional preparation appeared highest and the level of economical preparation showed lowest. The perception of successful aging indicated relatively high, and especially the level of comfortable everyday life showed highest. The results also showed that personal characteristics influencing on preparations for the old age were sex, age, marriage status, religion, occupation, monthly income, health condition, level of plan for the old age, and social activities frequency, and demonstrated that the perception of successful aging effected on preparations for the old age positively.

Objectives: This study examined the dietary characteristics and needs for community kitchens among young adults of single-person households in Seoul according to the cooking attitude. Methods: During April 2018, an online survey was conducted on young adults of single-person households in their 20s and 30s residing in Seoul. The respondents were classified into the more positive cooking attitude group (More Positive Group; n=152, mean=4.11) and the less positive cooking attitude group (Less Positive Group; n=190, mean=3.03) based on the mean score (3.51) of the 4-item 5-point Likert scales measuring the cooking attitude. The responses of the two groups were compared. Results: Approximately 90% of the More Positive Group had the cooking ability to prepare ordinary meals or more advanced cooking skills, whereas only 61% of the Less Positive Group had such skills. Approximately a half of the More Positive Group cooked at home three times a week or more; only 30% of the Less Positive Group did so, and more than 30% of the group seldom cooked. The More Positive Group had higher mean scores in the levels of satisfaction with dietary life and care for food safety and nutrition than the Less Positive Group. Approximately 30% of all the respondents expressed their needs for community kitchens. The most frequently answered reason for such needs was "being able to have a meal with others". Conclusions: The young adults of single-person households with a more positive cooking attitude possessed a higher cooking ability, cooked more often, and cared more about food safety and nutrition than those with a less positive cooking attitude. There were moderate needs for community kitchens among young adults of single-person households living in Seoul. Therefore, societal efforts to improve their cooking attitude would be meaningful for improving their quality of dietary life. Cooking lessons or social dining programs based on community kitchens could be an option.

The objective of this study was to examine both antioxidant activities and quality characteristics of sausages made from a mixture of purple sweet potato powder and pigment. Five sausages were manufactured: F0 (control), F1 (0.15%-sodium nitrite), F2 (0.2%-purple sweet potato pigment), F3 (0.2%-purple sweet potato pigment and 5%-purple sweet potato powder), and F4 (0.2%-purple sweet potato pigment and 10%-purple sweet potato powder). Sausages were stored at $4{\pm}1^{\circ}C$ for 30 days. Total polyphenol, 2,2-diphenyl-l-picrylhydrazyl (DPPH) radical scavenging activity, acid value, peroxide value, volatile basic nitrogen (VBN), and total bacterial cell contents were analyzed. Total polyphenol content and DPPH radical scavenging activity increased according to the amount of purple sweet potato, whereas acid value, peroxide value, and VBN decreased. Addition of 0.2% purple sweet potato pigment increased lipid oxidative stability and protein deterioration inhibitory effect compared to F0, but not to the levels of 0.15% sodium nitrite. However, F2 showed the lowest pH during storage due to the pH (2.52) of the pigment. Microorganism analysis revealed that total bacterial counts of sausage added with 0.2% purple sweet potato pigment were significantly lower (P<0.05) than that of sodium nitrite-supplemented sausage. As a result, purple sweet potato powder and pigment demonstrate antioxidative activity and lipid oxidative stability in sausages, making them suitable ingredients for manufacturing sausages.

With the recent increase of sensitivity to decors, there has been an ever-increasing significance of exhibiting the beauty of the outer looks of an article. This trend has necessarily led to the diversification and also specialization of the color scheme activities. And so, it is inevitable that we should form the substantial ideas of the color scheme and further on, enhance the efficacy of its orientation under the prevailing circumstances. Now, we come to a realization that we must first take a glance at the whole picture of the arrays of color embedded in a variety of articles in the sixties and seventies of the 20th century, a bold introduction of color designs, thereby tracing the birth of color designs and finding a meaning in its mechanism. This study begins with the obtaining of a large collection of articles in those days, along with the literature on the commercial effects color suggest, and looking into the background of their trend and finding a meaning that underlies what these colors suggest. The general idea of those color designs exemplifies that the color selection was none other than the simplicity and convenience in the making of things in doser relation to the easy selling. With the advance of material quality and enhancement of the industrial idealism, it has been proved that color plays an important role in depicting the image of quality and tastes of class. In that role color has been given the indicator of visual delights and differentials in quality articles. All this has been reflected in a diversity of articles: for instance, white for household appliances, prime color for living necessaries and natural color for the decore like furniture. Formerly, after all, people used to have little regard for color. What is color for, it was thought, in relation to the selling image of articles? That is wily our preceding generation pays attention only to the first-hand looks of articles, neglecting the intensive study on color. We are beginning to understand what image a certain color scheme evokes in our feeling.

When the soybean milk residue flour were added to the respective wheat flour at level of 5%, 10% and 15% the possibility of bread making were studied. Vital gluten was added to the soybean milk residue portion of a 10% composite flour at levels of 3%, 6% and 9% to improve bread quality. And test was baking properties of soybean milk residue composite flour and sensory evaluation of composite breads. Major components of soybean milk residue flour were crude protein, 22.0%; crude lipid, 13.2%; carbohydrate, 54.3%; and dietary fiber, 27.2%. When 5%, 10% and 15% soybean milk residue flour was blended with wheat flour, water absorption, development time and bread weight were increased, and volume of dough and loaf was decreased. But improved bread-making properties by adding gluten. Color of crumb got darker as the percentage of soybean milk residue flour increased, got brighter when gluten was added. Texture of bread increased in chewiness and hardness as the percentage soybean milk residue flour increased but not different in cohesiveness. The use of vital gluten showed influence to springiness, chewiness and hardness. The sensory evaluation showed that 5% soybean milk residue-wheat bread was similar to bread made from wheat flour in overall acceptability. And the bread made by miting gluten were better than 10% soybean milk residue-wheat bread in overall acceptability.
