This study was intended to identify the main factors responsible for the decline in purchase of imported agricultural and fish products after Japan's nuclear power plant accident in 2011 and to compare the effects on imported agricultural produce and imported fish products. Logit model and multiple regression model analyses were performed using consumers' survey data. Psychological and qualitative factors reflecting consumers' food safety awareness and purchasing preferences, which were extracted by Factor analysis, were included as the models' explanatory variables, along with socio-demographic and economic factors. The Logit estimation showed aged, married, and low-income households had significantly higher probability of reducing their purchases of imported agricultural and fish products. However, the multiple regression results pointed out that the actual rate of decrease of imported agricultural and fish products purchases were more significantly affected by non-socio demographic factors such as past experience of purchasing imported agricultural and fish products, future intention to purchasing Japanese agricultural and fish products, and the ratio of imported to domestic agricultural and fish products before the nuclear accident, as well as consumers' feeling of food insecurity and their purchasing preferences. Moreover, the results showed that Korean consumers have reacted more sensitively to the decline in imported fish products than imported agricultural produce after the nuclear accident based on the marginal effects of various socio-demographic and economic factors.

The purpose of this study was to investigate the university student's dietary behaviors, lifestyle and nutrition knowledge. The survey were composed of 81 male and 64 female students at W University in Daejeon. Results of survey shown that BMIs of male students was 23.9 which is higher significant at p<0.001 than female students was 20.8. In lifestyle, dietary habit patterns of female students showed higher significant in meal if under stress and snack intake at p<0.05. In terms of dining-out, both female and male students like Korean food. However, female students like Western food and flour-based food than their male counterpart. While male liked Chinese and Japanese foods at p<0.05. A siginificant higher proportion of male students smoked (p<0.001); drink (p<0.01) and exercised (p<0.05) than their female counterpart. In terms of nutrition knowledge, males have higher scores (out of a possible 15 points) than female scores (p<0.01). The results of this study suggests that nutrition education can motivate and improve dietary management for dietary compliance. Therefore, a proper planned nutrition education programs for university students is an efficient and effective education method.

The advent of the Internet and social media has given rise to a number of anti-milk articles that contain a lot of misinformation. Should milk and dairy products really not be consumed past a certain age? To answer this question, the history of milk consumption must be examined to understand the long-term benefits of milk. Historically, dairy products were among the foods served to the angels in the Old Testament of the Bible. Furthermore, dairy products were consumed even before the Bronze Age, and are defined by many food and animal scientists, and nutritionists as a complete food containing a lot of nutrients. Milk and dairy products have significantly contributed to the Korean and Japanese people's current body structures; this is evident in the fact that they are taller than their ancestors, primarily due to the increased consumption of milk and dairy products following industrialization. The average height of Koreans rose drastically in the 1960s, after milk consumption increased as a result of the dairy promotion policy. This article seeks to help understand milk by looking into the content published by a life insurance company in 1927.

Burdock (Arctium sp.) is known as a nutraceutical vegetable, especially in Japanese and Korean cuisine. While burdock plants are generally harvested for their tap roots, different parts of the plant are consumed as food or used as traditional medicines. This study investigated the physicochemical properties of the leaves, stems, roots, and peeled roots of the burdock plant based on their pH, soluble solid content, titratable acidity, color values, and mineral content. The pH differed significantly among the different plant parts, with the highest value in the leaves and the lowest in the stems. However, for the soluble solid content, the leaves had the lowest, while the peeled roots had the highest. The titratable acidity of the stems was significantly lower than that of the leaves, roots, and peeled roots. As regards the color values, the lightness value was highest for the stems, while the roots showed the highest redness value, followed by the peeled roots, and the leaves had the highest yellowness value. The leaves and stems contained almost three times more potassium than the roots and peeled roots. Thus, the higher content of different minerals in the leaves and stems of the burdock plant shows that these plant parts could be used as potential sources of dietary minerals.

Dog meat was begun to be edible by the Chinese, Japanese, the French, Belginan, German Philippines Vietnamese, North-Americans African-Indians Canadian-aborigines Alaskan aborigines including Kor-eans. According to the record, Korea has a long history to have eaten dog meat from the era of Sam-kug(three kingdoms BC 57∼AC 668) and so there are numerous languages proverbs, and customs re-lated to the dog meat. Over the long history there have been many records and recipes about the edib-leness of dog meat. But at present time only the way of cooking such as Bosintang(a soup) Suyuk(a boiled meat) Duruchighi(boiled meat added spice and slightly roasted) Muchim(boiled meat added by spice and mixed) Gaesoju(an extract) Jeongol(boiled meat mixed with spices vegetables and water on the pot) remains. Koreans eat dog meat following the traditional customs n the Boknal(hottest day in summer). Also the areas of Buyo. Sochon, Boryong adn Chongyang of Chungnam province and the ad-jacent areas like Kongju, Iksan, and Nonsan have customs to kill the dog and offer dog meat to the gue-sts in time of small or big occasions such as funeral ceremony Hoigap(anniversary of one's 60th birth-day) and one's birthday. This range of customs is expanding larger and larger. These areas are the cen-ter of past Baekche(BC 57∼AC 660). In spite of this it is unreasonable, and excessive action for foreig-ner to fine fault with the dog meat or Korean food culture.

Given the CYP3A4 and CYP3A5's impact on the efficacy of drugs, the genetic backgrounds of individuals and populations are regarded as an important factor to be considered in the prescription of personalized medicine. However, genetic studies with Korean population are relatively scarce compared to those with other populations. In this study, we aimed to identify CYP3A4/5 polymorphisms and compare the genotype distributions among five ethnicities. To identify CYP3A4/5 SNPs, we first performed direct sequencing with 288 DNA samples which consisted of 96 Koreans, 48 European-Americans, 48 African-Americans, 48 Han Chinese, and 48 Japanese. The direct sequencing identified 15 novel SNPs, as well as 42 known polymorphisms. We defined the genotype distributions, and compared the allele frequencies among five ethnicities. The results showed that minor allele frequencies of Korean population were similar with those of the Japanese and Han Chinese populations, whereas there were distinct differences from European-Americans or African-Americans. Among the pharmacogenetic markers, frequencies of $CYP3A4^*1B$ (rs2740574) and $CYP3A5^*3C$ (rs776742) in Asian groups were different from those in other populations. In addition, minor allele frequency of $CYP3A4^*18$ (rs28371759) was the highest in Korean population. Additional in silico analysis predicted that two novel non-synonymous SNPs in CYP3A5 (+27256C>T, P389S and +31546T>G, I488S) could alter protein structure. The frequency distributions of the identified polymorphisms in the present study may contribute to the expansion of pharmacogenetic knowledge.
