Rural Development Administration (RDA) has developed a manufacturing technology which can increase the amount of platycodin D in Platycodon grandiflorum. A study is needed to estimate the value of this new technology and predict the market demand for a new product. This study estimates additional amount of willingness to pay (WTP) using contingent valuation method (CVM) for a new product with the technology that RDA has developed. The survey was created under virtual health functional foods market of Platycodon grandiflorums. It was conducted with 1,000 adult males and females aged between 19 and 59 years old in 17 major cities and provinces nationwide from December 4 to December 7, 2018. The amount of WTP for the health functional Platycodon grandiflorum was drawn using maxinum likelihood estimation method. The estimated average and median WTP values are 21,933.85 won per person and 10,000 won per person, respectively. The independent factors, including the ratio of monthly average health function food consumption to income, the average monthly income level of a household, and existence of family members or relatives engaged in food and nutrition-related professions in a household, have been shown to have a statistically significant influence on the WTP. This study presents the potential magnitude of health functional food market and the value of the new technology based on health functional food market.

Purpose: The purpose of this study is to investigate levels of stress, self-esteem, and powerlessness in Korean husbands married to foreigner wives. Methods: The subjects were 183 Korean men who were living with foreigner wives in the Gwangju, Jeonnam and Jeonnbuk areas. Data were collected from January to May 2012 and analyzed by descriptive statistics, t-test, one-way ANOVA, Scheffe$\acute{e}$ test, Pearson's correlation coefficient, and backward multiple regression with the SPSS PC WIN version 18.0. Results: The average level of stress was 4.48, with difficulties in international marriage experienced by the subjects due to differences in language and culture. The average reported self-esteem score was 29.69, and the average powerlessness score 117.76. There were significant differences in perceived powerlessness depending on the employment statuses, income levels, and nationalities of the participants' wives, and their perceived levels of satisfaction with living with a foreigner wife. Powerlessness was positively correlated with stress (r=.41, p<.001), and negatively correlated with self-esteem(r=-.63, p<.001). The factors affecting the perceived powerlessness included self-esteem (${\beta}$=-.54, p<.001), stress (${\beta}$=.28, p<.001), lower income (${\beta}$=.13, p = .016), and working wife (${\beta}$=.12, p = .036). Conclusion: Healthcare providers need to explore strategies to improve self-esteem and powerlessness in Korean men married to foreigner wives.

This study was conducted to develop the standard breakfast menu for those weak groups having insufficient breakfast intake. The following three target groups are classified as: 16-19 years old high school male student, 20-29 years old female who have job or college students, 20-29 years old male or female who have job (double income family). While developing menus for each target groups, we applied several basic guidelines for meal planning as follows: Nutrient intake level was set to $\graction one-Third$ of RDA, while the energy level to $\fraction one-quarter $ of RDAs. Most Sequent meal pattern of Koreans was adapted; Suitabilities of appropriate serving size and cost for middle-income families were considered; Domestic foods and ingredients were used. We developed 24 menus summed by 2 menus for each season and three target groups. When evaluating the menus, most of the breakfast menus were sufficient of nutrients as a meal for the subjects. Three food groups such as grain/starch group, meat/fish/egg/bean group, vegetable/fruit group were included in all menus. Even though milk/dairy products group was not excluded for some menus, other calcium substitutes like anchovies were used. Oil/nut/sugar group was used to a minimum. The average number of foods for each menu was 12.8, which ranged from 10 to 17 depending on the menus. The average weight of the menus including soup was 822 g, 633 g and 730 g for each target group, respectively. The average price of the menu ranged from 2,000 to 3,500 won per person. The above results could be applied at home as well as foodservice institutes and furthermore could offer information for developing breakfast-substituting food products.

This study examines the relationship between population growth and carbon dioxide emissions in the context of Africa perspective. Population growth and carbon dioxide emissions helped identify the key driving forces of environmental impacts by including other predictors in all the different income levels of all sampled countries in Africa. To explore the role of population growth in the emissions of carbon dioxide, this research employed a panel data set of 52 Africa countries from 1960 to 2012 using fixed effects, random effects and GLS/FGLS estimators to estimate the modified STIRPAT model. The results found that a 1% increase in population growth suggests an increase in carbon dioxide emission loads by about 0.33%, 1.08%, 0.57% and 2.32% on the average, controlling for all other anthropogenic driving forces, for LICA, LMICA, UICA and HICA respectively. There is a significant relationship between population growth and carbon dioxide emissions in all the national income levels in Africa.

The status of the nutrient supplement usage of the adults in Seoul was investigated. One thousand two hundred adults from various age groups were chosen as the subject of this study. Data of this study were obtained by means of self administered questionnaire for demog-raphic characteristics(sex,age,edcation,income,occupation) and behavioral characteristics (reason for using nutrient supplement or not using,exercise,drinking & smoking). The overall response rate was 85%(n=1031). As a result, a substantial percentage(40%) of the subjects were used some kinds of nutrient supplement. The higher the age, educational level, and family income were, the higher the percentage of nutrient supplement usage was. But there was not the significant difference between sexes(38% in men vs 34% in women). And supple-ment usage was higher in the thin and obese groups than the average weight groups. Majority of subjects indicated that the information source of supplement was "Family/Friends" or "Phy-sician/Pharmacist". KEY WORDS: supplement usage vitamin/mineral supplement health food.

Method: Data were collected through questionnaires from 277 middle aged women. Collected data were analyzed using PASW Statistics 18. Analysis included descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and stepwise multiple regression. Results: There was a statistically significant difference in Yangsaeng according to average monthly household income. There was a significant positive correlation between Yangsaeng and self-efficacy, family support, and health perception. Health perception, family support, self-efficacy, and monthly income were found to be significant predictors (36%) of Yangsaeng.
