The aim of this study was to evaluate the TEMPOⓇ STA automated most probable number (MPN) system for the enumeration of Staphylococcus aureus (S. aureus) in comparison with a standard culture method. Artificially inoculated food products with S. aureus - triangle kimbap, sliced spring onion, dried filefish fillet, danpatjuk (sweet red-bean porridge with small rice dumplings)- were tested in this study. Twenty-five grams of each of food samples were added into 225 ㎖ of sterilized phosphate buffered saline in a TEMPOⓇ stomacher bag followed by stomaching for 2 min. One milliliter of the stomached sample was added to a bottle of culture medium. Cards were filled and sealed in the automated filler and then were incubated for 24 h at 37℃. After incubation, the cards were placed in the automated TEMPOⓇ reader and MPN results were generated. For comparison with a culture method, decimal dilutions were prepared from the same homogenized samples described above, transferred onto Baird Parker and Baird Parker-Rabbit Plasma Fibrinogen (BP-RPF) agar plates, and then incubated at 37℃ for 24 h. The performance of TEMPOⓇ STA method is equivalent to the culture method using Baird Parker or BP-RPF agar count plate for the enumeration of S. aureus in foods, eliminating a time-consuming and laborious process.

We surveyed the sanitary conditions for 17 cold and frozen food storage warehouses in Korea,using the following 5 inspections items: “putting into warehouse (A)”, “prevention of cross-contamination (B)”, “storage management (C)”, “temperature control (D)”, and “management of records and documents (E)”, We included 20detailed items. The results of distribution for frequency by five major inspection items showed that “(E)” was the highest,the next “(D)”, “(C)”; and “(B)” was the lowest. In the correlation of inspection scores between total scores, “(B)”and “(C)” were highly related to the total score, therefore, the higher score of “(B)” or “(C)”, the higher for the total score. In details of inspection items, “the management of cross-contamination upon taking product out of the warehouse”had the lowest score with a mean, of 2.67 ± 1.80, and also ranked as first of the 20 items.

Salmonellosis constitutes an important public health problem in both developing and developed countries, including Korea. The aims of present study were to investigate the serovar and antimicrobial resistance of Salmonella isolated from food animals and animal products in slaughterhouses and farms. A total of 323 Salmonella were isolated from food animals (n=277) and meats (n=46) during 2010. Of the isolates, 21 different serovars were identified. The predominant serovars were S. Rissen (35%) and S. Montevideo (24.3) in healthy pigs, while S. Enteritidis (25.5%) in healthy chicken. S. Typhimurium (88.8%) was predominant in disease pigs, while S. Gallinarum (29.2%) and S. Montevideo (26.9%) were in diseased chickens. Among meat samples, S. Typhimurium (57.1%) was the most common serovar in pork but S. Enteritidis (38.7%) and S. Montevideo(32.3%) were in chikcen meats. Analysis of antimicrobial resistance patterns revealed that 20.7% of the isolates were sensitive to all the 15 drugs tested. The isolates were frequently resistant to nalidixic acid (47.7%), tetracycline (38.4%), streptomycin (33.7%), and ampicillin (32.8%). The resistance to quinolone and 3rd generation cephalosporins was higher in chicken and chicken meat isolates. Of the 323 isolates, 174 (53.9%) were resistant to one or more CLSI subclass, and 117 (36.2%) showed multiple-resistance. Our findings showed that multiple resistant Salmonella organism are widespread in animals and animal products in Korea. To prevent the transmission or exposure for consumers of antimicrobial resistant Salmonella, policies and guidelines aiming at prudential use of critical antimicrobials for humans are needed.

Campylobacterosis is the most common food borne bacterial disease in many countries. Food animals and animal products are considered to be the reservoir of the Campylobacter species. The aim of this study was to investigate the antimicrobial resistance of Campylobacter spp. from food animals and raw meats in slaughterhouses. A total of 90 Campylobacter jejuni (C. jejuni) and 127 Campylobacter coli (C. coli) were isolated, for which antimicrobial susceptibility was examined using broth dilution method. Resistance to macrolide antimicrobials was higher among C. coli isolates than among C. jejuni. Among both C. jejuni and C. coli isolates, the most frequently observed resistance was to nalidixic acid, ciprofloxacin, and tetracycline. No erythromycin resistance was observed among C. jejuni isolates from cattle, pig and beef. However, 28.3% (n=13) and 25% (n=3) of C. coli isolates from pigs and pork showed resistance to erythromycin, respectively. The predominant profile of multiple resistance among C. jejuni and C. coli isolates was ciprofloxacin/tetracycline/nalidixic acid resistance (46.7%) and ciprofloxacin/nalidixic acid resistance (31.5%), respectively. This finding has important implication for food safety and public health.

The main goal of this study is to show promising future food market of Northeast Asia countries, including China, Japan, and South Korea. Drinks market, including soft and alcoholic drinks is selected to show global food companies new opportunities for next strategic movements. Market Attractiveness Matrix is developed based on BCG matrix as a main framework for this study. CDI (Category Development Index) is also used. It is found that Asia-pacific has fast-growing markets and it has strong potential for future investment. Northeast Asia countries (China, Japan, and South Korea) turned out to be ones of the most attractive regional markets. However, European drinks market is saturated even though its size is still big. This study suggests that Northeast Asian market be considered a market for the next strategic movement and investment.

The purpose of this study was to analyze methods and contents of global Korean food marketing. In-depth interviews were conducted from July to October in 2010 using a qualitative research approach. Government agencies and restaurant companies emphasized well-being and healthy aspects as a Korean food identity. Regarding the marketing contents, government agencies commonly included standard loanword orthography and recipes. On the other hand, restaurant companies contained their own contents differentiated from other brands. Government agencies used CF, video, book and newspaper as communication channels but restaurant companies did not have systematic communication channels. Government agencies attempted to use holding, supporting and participating expositions as communication methods, whereas restaurant companies mainly used sales promotion and point-of-purchase as communication methods.

This research analyzed the naming standard of Korea menu names divided into two groups, main dish and side dish. The research was conducted by contents analysis of selected literature articles and multiple-response cross tabulation analysis. The result demonstrated that the naming standard of Korea food consisted of the main ingredient name - sub ingredient name - main condiment name and main recipe. On the other hand, the menu name that is in native language or has a historical origin is exempt from this classification. Therefore, this study proposes a new standard, 'Hansik Menu Naming', to assist the food service industry and correct the names of unknown foreign dishes.

This study attempted to identify differences in Korean food consumption behaviors between groups of Japanese consumers segmented in accordance to their food-related lifestyles. This study was performed to provide Korean food service companies basic information to implement a strategy for the globalization of Korean food. As a result of the empirical analysis, the food-related lifestyles of Japanese consumers were deduced to the following four factors: "health and safetyoriented lifestyle", "palate and safety-oriented lifestyle", "economic efficiency-oriented lifestyle", and "simplicity-oriented lifestyle". Further, as a result of the cluster analysis, food-related lifestyles were classified into the following three groups: "a group highly interested in food-related life", "an economic efficiency-oriented group", and "a simplicity-oriented group". Second, there were significant differences in demographic characteristics and the characteristics of Korean food consumption behaviors between the groups. Third, also in a comparison of satisfaction with and loyalty to Korean restaurants with crucial attributes during the selection of Korean food, there were significant differences between the groups. Therefore, it is necessary to develop various Korean food products that will cater to Japanese consumers in accordance with each segmented group.

This study was intended to outline the characteristics of the food culture in the area of Kyungsangnamdo and its modernization by interpretation and analysis of the novel Toji, which was set in Hadong, Jinjoo in the area of Kyungsangnamdo in the early 20th century. The characteristics of the Kyungsangnamdo area's native dish during the Japanese ruling era in the latter half of the Choson dynasty are as follows. In the first part of the novel, which spans from 1897 to 1908, vegetable and grain food development can be seen in the area of Hadong, the interior plains of Kyungsangnamdo, where there is a typical farming village in the mountains. The second part of the novel, which spans from 1911 through 1917, includes some mentions of the properties of Kyungsangnamdo area's native dishes through the lens of emigrated Koreans living on Gando island. Gando island is in China, and is where Seohee, the heroine, escapes from her homeland and remains for a period of years. There is a unique type of seafood in the Gando area using fresh marine products, exactly the same as in the Kyungsangnamdo area. The third part of the novel spans 1919 through 1929, after Seohee returns to her own country and regains her house. There is a noticeable description of food culture in the area of Jinjoo in Kyungsangnamdo through the description of Seohee focusing on the education of her children. The well-described features of Jinjoo are boiled rice with soup of beef leg bones and Jinjoo bibimbob, with vegetables and a variety of foods using cod. Cod are caught in large quantities in Kyunjgsangnamdo, and cities in the area grow to medium size as the area became traffic-based. The fourth part of the novel spans from 1929 through 1938, and includes very detailed descriptions of characters and background locations. Salted fish combined with the wild ingredients of Mt. Jiri feature prominently in the Kyungsangnamdo's area descriptions. The fifth part spans from 1940 through 1945, and as the Japanese colonization era ends, the foods described in Kyungsangnamdo seem to develop the usage of soybean paste. With abundant fish and shellfish Kyungsangnamdo, the dishes that evolve to use soybean paste include mussel soybean paste soup, picked bean leaves in soybean paste, chaitgook - cold soup from soybean paste, and seolchigook used with seaweed and sea laver.

The aim of this study was to classify Korean consumers based on their food-related lifestyle type, and to investigate the relationship between sushi consumption and food-related lifestyle type. Self-reported questionnaires were completed by 300 Korean adults. The SPSS 18.0 program was used to analyze the samples. Data was analyzed by frequency, descriptive factor, reliability, cluster analysis, ANOVA, and chi-square test. A factor analysis extracted four factors comprising foodrelated lifestyle, which we named Health-seeking (factor 1), Taste-seeking (factor 2), Convenience-seeking (factor 3), and Economy-seeking (factor 4). According to a cluster analysis based on those four factors, consumers were classified into three clusters. Cluster 1 was the Taste and Health-seeking cluster, Cluster 2 was the Convenience-seeking cluster, and Cluster 3 was the Passive Eating Habits cluster. The results also indicated that the selection attributes of each cluster were significantly different in terms of perception, the global state of sushi, sushi preference, frequency, companions, place of sushi consumption, and preference for different sushi sub-ingredients. Based on these results, consumer characteristics in the sushi market are discussed.

This study was intended to examine the continuance and transformation of food culture during the enlightenment and Japanese ruling era by analyzing the novel of "Toji". In the novel "Toji", the chaotic political and economic situation is reflected, along with the peoples' hard lives in the latter era of the Choson Dynasty. After the full-fledged invasion of China by the Japanese, the shift to a wartime posture was accompanied by an increased need for food. This led to a rationing and delivery system for rice in the late 1930s. While it was hard for people to obtain even brewer's grains and bean-curd dregs, food distribution officers were well off. Another distinctive feature of the food culture during the enlightenment and Japanese ruling era was that foreign food and recipes were introduced naturally to Korea through the influx of various foreigners. The industry of Choson was held by Japanese monopolistic capital, as a result, Choson had equal to the role as a spending site and was only gradually left destitute. In the Japanese ruling era, there were new type of business including such as patisserie of the types of civilization in the town, and those tempted Korean people. However, the Japanese and pro-Japan collaborators dominated commercial business. Being urbanization through the modernization, it was became patronized fast food in the populous downtown, and the change of industry structure and life style greatly influenced into our food culture. Acceptance the convenient Japanese style fast food such as Udong, pickled radish made was actively accepted with a longing for the advancement civilization. After the enlightenment, many Japanese exchange students went to Tokyo to get advanced civilization and provided urban mood according to their consumption of bread, coffee, Western food, which were considered a part of the elite culture.

음식물 폐기물 침출수를 처리하는 분리막 결합 고온 혐기성소화공정(생물학적 반응조) (Anaeorobic Membrane Bioreactor, AnMBR)의 파일럿 운전에서 분리막의 교차여과 속도와 막간압력이 파울링에 미치는 영향을 관찰하였다. 연구 결과 정압여과 하에서 교차여과 속도가 증가할수록 파울링의 속도는 현격히 감소되었다. 그러나 이와 같은 영향은 낮은 막간압력에서 더욱 효과적이었다. 막간압력이 증가할수록 여과대상 물질의 압축성으로 인해 투과성이 상대적으로 낮은 파울링층(혹은 케익층)이 분리막 표면에 형성된 것에 기인된 듯하다. 여과대상 시료의 입도분석을 해 본 결과 입자크기는 약 10~100mum 범위에서 분포하였고 이에 따라 브라운확산에 의한 역수송보다 분리막 표면에서 교차여과에 의해 발생하는 전단력이 입자의 역수송에 더욱 기여하고 있음을 예측할 수 있었으며 이는 AnMBR의 연속운전을 통해 재확인할 수 있었다. 운전 후 막 부검을 실시한 결과 유기 및 무기 파울링이 모두 관찰되었으나 어느 것이 지배적인 파울링 기작을 나타내는지는 앞으로 더욱 연구가 필요하다. 무기 파울링의 경우 대부분 분리막 표면에서 스케일링 형성이 지배적이었으며, 따라서 분리막의 공극 막힘에 주로 기여하는 작은 콜로이드성 유기물질의 경우 분리막 표면에서 전단력에 의한 역수송 효과는 그다지 크지 않을 것으로 사료된다.

Due to an overall increase of income, the general standard of living has improved and people have begun to be interested in being more healthy in their lives. This tendency has affected the food market, especially in relation to organic and eco-friendly food. Thus, the overall market size for those products has grown to give more choices to consumers. To examine the effect of the motive for choosing certain food products on the actual attitude and intent to purchase the products, a survey was given to 330 people living in Seoul, which resulted in 235 usable responses. The content of the questionnaire consisted of 18 questions on food choice motives, 3 questions on the attitude toward organic foods and 3 questions on the intention of purchasing for organic foods. The SPSS 12.0 statistics program was used to analyze of following: frequency analysis, factor analysis, reliability analysis, t-test, one way ANOVA and regression analysis. Five factors of food choice motives were obtained from the analysis: health, convenience, price, familiarity and environmental protection. The regression analysis showed that food choice motive, health and environmental protection factors have a positive relationship with organic food attitudes and organic food attitudes have a positive relationship with the intent to purchase organic food.

Student and dietitian reactions to a multicultural food service menu were studied. Food habits in a multicultural family could delay the acculturation of the children to traditional Korean food and could cause the isolation of children from the community. Also, Korean students need to be exposed to other cultures and foods because it can be a challenge to eat novel foods when students grow up. To help both multicultural and Korean children adjust to new foods, a multicultural menu was included in a school's food service. Students regarded the multicultural menu as access to another culture, but they felt that improvement of the food quality and menu diversity were required. The degree of satisfaction with the food quality, appearance, freshness, temperature, and menu diversity were all moderate. The multicultural menu was served as a single menu item or a combination menu item. The main dish single items - pasta, jajangmyeon, onigiri, hamburgers, rice and curry, kaupatmu, kaupatkung, and donburi - were liked, but nasi goreng was liked only moderately. The soup - based dish single item, tempura soba, was liked, while tomyum was disliked. The side dish single items - tangsuyook, Japanese donkatsu, baked sausage and potatoes, tandoori chicken, chicken britto, Vienna schnitzels, tender tortillas, and fried chicken wings - were liked. The desserts single items-sandwiches, pineapples, waffles, pizza, bread with strawberry jam, mangoes, and tacoyaki - were liked. The combination menus - Italian, Indian, and American - were liked, but the southeast Asian menu was the least favored. Acceptance of combination and single menu items were similar. Male students liked multicultural menu items more than female students in all categories. Approximately 60% of dietitians had experience serving the single menu items for multicultural food service. The appropriate serving times were twice per month. Dietitians guessed that 80% of the students liked the multicultural menu. The dietitians preferred serving American or Chinese foods to southeast Asian food. There were two difficulties in serving the multicultural menu, which were voiced as as lack of skill in cooking the items and improper cooking utensils and tableware for the items. Despite all the difficulties, the dietitians served the multicultural menu because it provided menu diversity, rather than for educational reasons.

Optimum preparation conditions for chicken head soup base were determined in terms of the effects of amount of chicken head and cooking time using response surface methodology based on sensory properties. Sensory properties that were evaluated were yellowness, turbidity, bloody, chicken-brothy, organ meat-like, and fat-like flavor. All values of sensory characteristics increased remarkably with an increase in the amount of chicken head and cooking time. The optimum amount of chicken head and cooking time were determined to be 1800 g and 150 minutes, respectively. Chicken head soup base had less fat, free amino acids, nucleotides, and its derivatives, but had significantly more cholesterol, sodium, and iron than whole chicken soup base. In flavor compound analysis, the amount of hexanal of the chicken head soup base, which is related to fat rancidity flavor, was 11-fold higher than that of the whole chicken soup base.

This study was performed to approach the 2004 case of inferior quality mandu stuffing from the stance of food ethics. The court convicted the producers of inferior quality mandu stuffing and also decided against the plaintiffs who filed a damage suit. The core of the mandu stuffing case was not safety, but the wholesomeness. The principles of food ethics include a respect for life, justice, environmental preservation, and the priority of safety. The virtues of food professionals include wisdom, honesty, faithfulness, courage, moderation, and integrity. A food producer should possess not only the ability but also the morality to make food. The consumer should urge the producers to strengthen their morality and be conscious of responsibility and fairness. The government should organize a system to establish food ethics, and make efforts to reduce wasteful law enforcement. The media should lead public opinion toward justice by doing an unbiased and in-depth report and help establish the idea of food ethics. The necessity of food ethics and the spread of the ethical mind are the most important points of all.

An individual's food-related personal traits play an important role in influencing personal food choice and habits. According to culture, their influence can manifest differently. To ascertain personal traits about food, FNS (food neophobia scale) and FIS (food involvement scale) were employed in recent studies. This study aimed to understand the food culture and food choices of East-South Asians who live or stay in Korea through comparison of FNS and FIS. Eighty Koreans and 233 East-south Asians (Indonesians, Filipinos, Malaysians, Vietnamese, Thai, Singaporeans, and Bangladeshi) completed a questionnaire to measure FNS (10 questions), FIS (12 questions), and sociodemographic conditions (9 questions). ANOVA was conducted to ascertain FNS and FIS between the groups, and regression analysis was carried out to determine which sociodemographic factors had an effect. The items were analyzed to determine the differences according to gender, age, marital status, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. FNS showed significant differences between the groups with regard to sociodemographic characteristics, except gender, age, and marital status, whereas FIS showed significant differences in gender, nationality, religion, occupation, educational background, monthly income, and length of residence in Korea. The results of the regression analysis suggest that nationality strongly affected FNS and FIS, and FIS was also affected by gender.

Historically the rise of contagious diseases and epidemics has been mainly caused by lack of food safety knowledge and negligence in personal hygiene. Food poisoning is an example that have been caused by lack of proper knowledge in food safety and personal hygiene. In order to prove this hypothesis, our team distributed a total of 225 survey sheets to middle school students. Survey questions mainly focused on the students' food safety knowledge, personal hygiene and regular dietary habits. We used 12 items to determine the stages of change in teenagers and divided into 3 stages of change: precontemplation stage (poor problem recognition), contemplation and preparation stage (some problem recognition), and action stage. Out of the 225 students surveyed, 105(47.1%) were male and 118 (52.9%) were female; 44.0% were in 7th grade, 33.0% in 8th grade, and 24.0% in 9th grade. In stages of change model, 3.8% were classified in pre-contemplation stage, 31.1% in preparation stage, and 65.1% in action stage. The awareness of the significance of food safety has a strong positive correlation with the stages of change food safety behavior (P<0.001), which suggesting our questionnaires regarding stages of change and food safety behavior were quite credential. Stages of change were also correlated with the consumption of unsanitary foods (P<0.01) and with the frequent hand washing (P<0.05). The stages of change showed a positive correlation with the food safety knowledge level (P<0.05). The four questions (out of 10) with the least percentage of correct answers were questions about the meaning of Norovirus (23.6%), the meaning of expiration date (43.6%), the meaning of food poisoning (36.4%), and proper food-handling (36.0%).
