BACKGROUND/OBJECTIVES: The concept of "food deserts" has been widely used in Western countries as a framework to identify areas with constrained access to fresh and nutritious foods, providing guidelines for targeted nutrition and public health programs. Unlike the vast amount of literature on food deserts in a Western context, only a few studies have addressed the concept in an East Asian context, and none of them have investigated spatial patterns of unhealthy food consumption from a South Korean perspective. SUBJECTS/METHODS: We first evaluated the applicability of food deserts in a Korean setting and identified four Korean-specific unhealthy food consumption indicators, including insufficient food consumption due to financial difficulty, limited consumption of fruits and vegetables, excessive consumption of junk food, and excessive consumption of instant noodles. The KNHANES 2008-2012 data in Seoul were analyzed with stratified sampling weights to understand the trends and basic characteristics of these eating patterns in each category. GIS analyses were then conducted for the data spatially aggregated at the sub-district level in order to create maps identifying areas of concern regarding each of these indicators and their combinations. RESULTS: Despite significant reduction in the rate of food insufficiency due to financial difficulty, the rates of excessive consumption of unhealthy foods (junk food and instant noodles) as well as limited consumption of fruits and vegetables have increased or remained high. These patterns tend to be found among relatively younger and more educated groups, regardless of income status. CONCLUSIONS: A GIS-based analysis demonstrated several hotspots as potential "food deserts" tailored to the Korean context based on the observed spatial patterns of undesirable food consumption. These findings could be used as a guide to prioritize areas for targeted intervention programs to facilitate healthy food consumption behaviors and thus improve nutrition and food-related health outcomes.

This study was conducted to examine the 2nd broadcasting cooking program of Gyeongseong Radio from April 26th 1933, when the 2nd broadcasting for Koreans started, to December 1941. From its opening date, there were continuously regular cooking programs such as 'Recipes' and introducing 'Japchae'. Analysis of names broadcasted in cooking programs included a total of 452 foods (328 types); specifically, 332 Korean foods, 71 Western foods, 24 Japanese foods, 18 Chinese foods, and seven other foods. Korean foods included 35 staple foods, 223 side dishes, 64 deserts, and 11 sauces. Western foods included seven soups, 25 main dishes, and 25 deserts. Main dishes included many deep-fried dishes, while diverse types of desserts were also introduced. In the case of Japanese food, there were many foods combined with Western food. Chinese food included many types of dumplings and fried rice, as well as many dishes using pork. Among people broadcasting cooking programs, there were 11 whose names were shown in the schedule, all of whom were recognized as the best cooking specialists and educators of the time.

The purpose of this study was to apply molecular gastronomy and spherification methodology to persimmon deserts. We prepared 'persimmon calcium alginate beads' and investigated their physical and sensory characteristics by adding different concentrations of sodium alginate (0.4, 0.6, 0.8, and 1.0%). Lightness and yellowness decreased significantly as the concentration of sodium alginate increased. However hardness, springiness, chewiness, cohesiveness, and resilience but not adhesiveness tended to increase as the concentration of sodium alginate increased. The thickness of the beads increased as the concentration of sodium alginate increased. In contrast, the thickness of the membrane decreased as the concentration of alginate increased from 0.8 to 1.0% suggesting that the amount of sodium alginate had reached a critical point. Quantitative descriptive analysis showed that voluminosity, springiness, hardness, chewiness, and residue tended to increase as the concentration of sodium alginate increased. Overall preference reached a peak at 0.4% sodium alginate.

S. komarovii is halophyte that grows in soil or waters of high salinity, such as in saline semi-deserts, sloughs and seashores. Traditionally, S. komarovii has been used for food and medicinal purposes in Korea. S. komarovii was extracted in 70% ethanol to measure anti-oxidative activity using DPPH and ABTS assay. The IC₅₀ values of the S. komarovii extract against DPPH radicals and ABTS radicals were 186.10 mg/mL and 121.89 mg/mL. In addition, total polyphenol and reducing power were measured. The S. komarovii extract exhibited superior polyphenolic (22.5%) and antioxidant (28.4%) contents. Regarding cell bioactivity, MTT assay was conducted to reveal cytotoxicity of S. komarovii extract and showed the non-cytotoxicity of S. komarovii extract. Anti-inflammatory and skin whitening effects were measured at 100 ㎍/mL. Therefore, this study suggests that the S. komarovii extract can be used as a functional cosmetic product material.

The aim of this study is to consider the degree of supply-demand balance in relation to the characteristics of retail sale activities in depopulation aging regions and the degree of aging by using simple regression analysis. The major findings of this study are as follows. While aging society, and aged society regions show a similar major retail sale industries, super-aged society shows fewer major industries and different industry composition. These characteristics are seen by different phenomenon and the background of the particular retail structure. The first one is that the number of employees per establishment increases when the aging phenomenon is not accelerated, and the annual sales per capita purchasing power decrease because their purchasing power becomes lower when the aging phenomenon is severe, but it also shows a high density of establishments because disperse location of establishment within depopulation aging region. The second one is the retail structure with high labor productivity in a aged and superaged society region. We identify the extent of demand and supply in general retails, fuel retails, food and beverage, and tobacco retails which represent the highest sales rates in depopulation aging region. As a result, general retails are seen as 'supply-demand balance region' in aged and super-aged society, fuel retail sales in aged and super-aged society which generally shows less sales, and food and beverages, and tobacco retails in super-aged society. The higher the degree of aging is, the less the regional differences in the gap between demand and supply is. This is because the difference in purchasing power between these regions is small.
