It is estimated that the elderly will constitute 24.3% of the entire Korean population in 2030, when about 7,125,000 baby boomers reach retirement age. Therefore, this aging phenomenon might be the most urgent issue facing Korean society. The baby boom generation shows a strong tendency to dispose of existing residences or move into new housing after retirement, thereby exerting enormous impacts on social and economic sectors as well as the housing market. Against this backdrop, this study aims to identify both factors and patterns behind baby boomer retirees' post-retirement housing transfer trends. To this end, a survey is undertaken here with respect to those baby boomers living in Gangnam-gu and Seocho-gu with actual housing transfer plans in the foreseeable future, and who can act as a practical consumer group for the future housing market. This study verifies baby boomers' diverse preferences for housing type. Their preference for apartment houses still remains high in every situation, and this has significant implications for changed preferences of other housing types considering that most of the survey respondents currently reside in apartment houses. According to the survey, there are more than 80 kinds of baby boomers' housing transfer patterns, which demonstrates that more than half of the survey respondents pursue different housing mobility plans. When it comes to the factors behind their housing selection, the baby boom generation shows a strong preference for physical factors. However, environmental and psychological factors gain more momentum under unfavorable circumstances, while social factors play a decisive role in their housing selection in categories such as 'couple/deteriorating health' and 'single/healthy'.

This paper investigates whether intra-household bargaining power affects couples' caregiving decisions during instances of competing parental demands for assistance. The primary focus is on examining how partners' bargaining power influences the relative allocation of time resources between parents and parents-in-law, assuming that children prefer to transfer caregiving resources toward their own parents over their parents-in-law. The findings in this study reject the bargaining theory that couple's parental care behavior results from a bargaining process between the husband and the wife. More specifically, the results did not clearly show that children prefer to transfer caregiving resources toward their own parents over their parents-in-law. Decision-making power, measured by final decision-making authority, also failed to affect the relative care transfers.

The market size of engineered nanoparticles is rapidly increasing due to the fast application of nanotechnologies into different industries and consumer products. The development of new technology and materials has improved human's quality of life, but it also entails the possibility of exposure to new materials. In this study, we compared the distribution in the body by the inflow of silver nanoparticles having another diameter and shape at 1 h or 24 h after injection via the tail vein. And, we compared the cell composition and cytokine concentration in BAL fluid, and histopathological changes. As results, discharge of silver nanoparticles having small diameter and sphere shape was more rapid than that of big diameter or plate shape. It is estimated that the toxicity in liver and lung was proportional to accumulation level. The persistence of inflammation was also longer in mice treated with plate shape. Consequently, we suggest that the first choice of silver nanoparticles having small diameter and sphere shape in applying is desirable.

Quality characteristics of commercial yoghurt powder products marketed in Korea were compared. According to the product type classification, no product met the product identity of "fermented milk powder" (six were identified as "other processed product" and nine as "sugar product"). Titratable acidity of products (10%, w/v) varied from 0.11 to 0.82% while numbers of lactic acid bacteria varied from 0 to $1.4{\times}10^8CFU/g$. There were significant differences in hydration properties and viscosity of yoghurt powder products. Some regulations are required to avoid consumer misunderstanding of beneficial health effects of yoghurt powder products.

This study conducted a survey on the recognition and demand such as recognition level, policy necessity, service demand and policy demand by supply types in order to provide the basic data for successful settlement of agro-healing services. According to the survey on awareness, 45.2% of respondents were aware of the healing farming, and 31.3% of respondents had experience in participating in the agro-healing services. 63.6% of respondents replied that they were experiencing reasons for participating in agro-healing services. Respondents who had no knowledge of agro-healing services responded that 76.7% of respondents said they would not participate. More than two-thirds of respondents in all types indicated that they needed agro-healing services. As a result of evaluating the maximum willingness to pay, there was a willingness to pay for farm work healing about 15,800 won, horticulture healing about 14,800 won, forest healing about 13,400 won, and animal assisted healing about 17,000 won. Improving accessibility and strengthening awareness were high priorities for inconveniences and improvements. 70.1% of the respondents said that policies for agro-healing services are needed. Development of agro-healing programs and contents was the first priority for support policy. The result of this study is expected to provide reference data that can be suggested for agro-healing policy establishment.

In this study, questionnaire were made to environment-friendly producers of apples regarding farm management methods in low-input production method. utilizing organic materials, production and marketing of apples with lower agricultural chemical residues. Besides, five apples farms were visited to find out their management situation by employing the low-input production method in order to protect the environment as well as consumer's health. Those five low-input apple farms were scattered in Kyungbuk, Chungnam, and Chonnam Provinces, There were not many low-input apple farms across the nation from the beginning and, as a result, increasing the sample size was basically very difficult. Most of these farms were using 140hrs of labor per 10a, of which 30hrs in pre-season management, 25hrs in plowing and weed control, 15hrs in disease and pest control, 20hrs in harvest and marketing and 50hrs in miscellaneous activities. Relatively, pest control takes much time in that they would spray pesticides 7-10 times a season to control the apple disease, 9 times on the average. The average gross revenue of low-input apple farms was about \2,000,000/10a, and their average yield was 2,000kg/10a, which are 25% and 13% lower, respectively, than the ordinary apple production case. This means the low-input farmers are inefficient in marketing their products. On the other hand, their production costs were 20.4% higher than the ordinary apple farms on the average. Since the imported foreign fruits including apples must use various agricultural chemicals on their way to the export markets, the domestic low-input apples have competitive edge over them in therms of food safety. In order to improve the low-input apple industry, active cooperation is needed among the producers, government and researchers more than ever. Among other things, production cost reduction and quality improvement with lower chemical residues are part of the urgent matters to be done.

As a result of life-style changes, consumer's concerns of food have shifted from calories and nutrition to health and convenience. Fresh-cut products are one such new direction for fruit and vegetable consumption. In this study, the vitamin C, mineral, and pesticide contents of various fresh-cut products were analyzed. According to sensory evaluations, the key reason for a lower than expected overall acceptability of many fresh-cut products is that they are likely to have browning and can easily lose their freshness. Also, the sensory evaluation showed that shriveling, the degree of browning, softening around the cut edge, and off-flavors were the primary factors affecting the quality of fresh-cut products. As a nutritional factor of quality, vitamin C content was not practical with regard to fresh-cut lettuce because the level was very low. For product safety, residual pesticides were detected in the fresh-cut products, but the results showed that all items were under permitted levels and considered safe. In evaluation of the microbial levels of the fresh-cut market products, the levels of viable cells, mold, yeast, coliform bacteria, and enterobacteriaceae were not significantly different based on the summer and winter seasons. The levels of S. aureus and Listeria spp. in the products were higher during the summer season than the winter.

Compulsive hoarding becomes a problem when the spaces hoarded items are stored in become unusable due to clutter, health, or safety issues. Our research purpose was to document relationships between two non-normative consumer behaviors (compulsive hoarding, compulsive buying tendency) and two shopping-related variables: hedonic shopping motives and emotional attachment to possessions with everyday consumers. As hedonic shopping motives have been related to compulsive buying, we predicted these motives (e.g., adventure, gratification, role, value, social, and idea) are related to compulsive buying. We also examined the relationship between compulsive buying and compulsive hoarding tendency and whether emotional attachment to possessions moderated this relationship. Participants were 280 undergraduate and graduate students attending a Midwestern university in the U.S. Regression analysis revealed the enhancing emotion motive (a combined motive of adventure and gratification) positively influenced compulsive buying whereas the value motive negatively influenced compulsive buying. All other hedonic shopping motives were non-significant. Participants who tended to buy compulsively were likely to hoard compulsively. This relationship, however, was moderated by participants' emotional attachment to possessions. Participants with high emotional attachment to possessions showed a higher level of hoarding behavior than those with low emotional attachment to possessions. However, the increase in hoarding tendency among participants with low emotional attachment to possessions was larger between those who were low in compulsive buying and those who were high in compulsive buying than the increase between these two groups among participants with high emotional attachment to possessions.

This study examined the degree of socioeconomic deprivation in the areas of material hardship, health, housing, employment, and social network among people using debt relief programs. The sample, 209 individuals, was recruited from major agencies offering debt relief programs, including Seoul Bankruptcy Court, Credit Counseling and Recovery Service, and Seoul Welfare Foundation. Data were collected through in-person interviews in 2016. The sample was compared in terms of the level of deprivation with the general population and the low-income group, extracted from the Korea Welfare Panel Study. The debtors group demonstrated a substantially higher level of deprivation on all the dimensions examined. For example, the proportion of people who suffered from hunger was 37.8% in the debtors group compared to 6.7% in the low-income group. The proportion of people who had suicidal ideation in the last 12 months was 57.9% compared to 19.2% in the low-income group and 2.7% in the general population. The level of deprivation was different by chapter choice of consumer bankruptcy. Policy and practice implications of the results were discussed.
