The purpose of this study was to investigate the effect and correlation of anthropometric data, eating behaviors, and nutrient intake on the bone mineral density(BMD) of female college students. 349 female college students were surveyed and their age, height, and weight were an average of 20.5 years, 163.2 ㎝ and 54.0 ㎏, respectively. Their average BMI was 20.2, with 66% falling in the normal range, 21.8% classified as underweight, 8.0% as overweight, and obese individuals comprised 3.4% of the sample by BMI classification. Calcaneal BMD was measured and the average T-score was 0.117. The results of BMD measurements were normal in 268 people(76.8%), osteopenia was found in 71 individuals(20.3%), and osteoporosis in 10(2.9%), respectively. There was a significant difference in bone mineral density according to height(p<0.05) and BMI (p<0.01). There were significant differences between BMD and eating behavior, regularity of eating behaviors(p<0.05), instant food intake(p<0.05), eating out(p<0.05) and nutritional supplement intake(p<0.05). In addition, normal the group with normal BMD had a more desirable eating behavior compared to the osteopenia and osteoporosis afflicted groups. BMD had a significant difference according to the nutrient intake of calcium(p<0.05), vitamin A(p<0.05), and vitamin C(p<0.05). In conclusion, BMD showed a good correlation with height(p<0.01), BMI(p<0.01), body composition including total body water(p<0.05), FFM(p<0.05), body protein(p<0.05) and intake of calcium(p<0.05), iron(p<0.05), vitamin A(p<0.05), and vitamin C(p<0.05). Therefore, an education plan and training on balanced diets proper body weight control, and desirable eating behaviors for female college students will be needed.

The purpose of this study was to compare convenience food purchasing behaviors and food habits. The study, which asked surveyed 131 female college students in Daejeon, in 2011, on how they used nutrition labels. The subjects were divided into two groups, in terms of the way they checked examined nutrition labels: a "Check" group(n=62, 47.3%) and a "No check" group(n=69, 52.7%). Reasons given for not reading nutrition labelings were "a habit of buying" for 72.2%, and "too small or rude" for 19.1%. The "Check" group reported higher interest in nutrition(p<0.001) and hygiene(p<0.01) than the "No check" group. Those who used the labels had higher cereal(p<0.01) and vegetable(p<0.01) consumption and a lower intake of fast foods(p<0.05). But however, most of the subjects(65.6%) chose by taste, at the time they purchased the convenience foods. The subjects considered "expiry date"(n=87, 66.4%) to be more important information on food labels than "nutrient composition"(n=11, 8.4%). The number of products whose nutrition labels were checked by over 50% was five out of 12. In conclusion, our study suggests that proper use of nutrition labeling may improve food choices and enable healthy dietary practices. Further efforts are needed to provide the public with nutrition education programs on how to read nutrition labeling. Modifying nutrition labels to make them easier for the public to understand should also be considered.

본 논문은 음식물쓰레기의 퇴비화에 타당성을 위한 총론적인 논문이다, 또한 다양한 연구논문들을 조사함으로써 음식물 쓰레기의 퇴비화를 통해 얻어진 최종산물이 휘발성 유기화합물 및 냄새제거를 위한 바이오필터로서 적합성을 제고해 보고자 하였다. 우선 음식물쓰레기는 높은 유기물 함유량을 가지고 있어 퇴비화에 적합하지만 반면 높은 수분함량과 물리적으로 낮은 강도로 인해 퇴비화 과정을 어렵게 할 수 있다. 많은 연구자들에 의해 퇴비를 이용한 바이오필터링에 대한 연구가 진행중임에도 불구하고, 명확한 메커니즘의 규명이 되어 있지 않고 있으며 특히 음식물쓰레기에 대한 연구는 미비한 실정이다. 따라서 본 논문에서는 특히 음식물쓰레기 퇴비의 바이오필터로서의 사용가능성에 대한 기본적이고 중요한 자료를 제공하고자 한다.

From results of three components analysis about food waste, moisture content appeared high in order of school(89.1%), townhouse(64.9%), apartment(63.2%) and home(63.2%). And content of ash also appeared high in order of school(8.8%), townhouse(6.3%), apartment(5.4%) and home(4.2%). This is judged as cause of difference of moisture content according to emission-source, diversity of kind of cooked food and volume-rate disposal system which is not performed. Meanwhile, combustible content is 10.9~32.6% and it is the most highest in order of home, apartment, townhouse and school. And big difference of standard deviation of apartment and townhouse is judged as difference of homogeneity due to co-emission of food waste. In addition, Low heating value appeared high in order of home(1086.07 kcal/kg), apartment(1033.69 kcal/kg), townhouse (678.07 kcal/kg) and school(9.18 kcal/kg). And the reason that heating value of school is very low is error about simple formula which is applied when moisture content is more than 50%. And it can be confirmed that this is difficult in analysis of Low heating value of food waste.

To evaluate the indoor air quality of food manufacturing plants, the presence of viable bacteria and fungi was assessed in the indoor air of the facilities at which 9 food items were manufactured. Air samples were collected from the general zone, low clean zone and clean zone of each factory with an air sampler, in combination with plate counts agar using for bacteria, and dichloran-glycerol agar for fungi. The samples were incubated at 25℃for 4 to 7 days. After culture, the colony forming units (CFU) on each plate were counted and corrected with a positive hole conversion table. The average concentration of bacteria was 2.2 × 10³ CFU/㎥ in the general zone, 1.2 ×10³ CFU/㎥ in the low clean zone and 7.3 × 10² CFU/㎥ in the clean zone. The average concentration of fungal microbes was 2.5 × 10³ CFU/㎥ in the general zone, 2.6 × 10³ CFU/㎥ in the low clean zone, and 2.0 × 10² CFU/㎥in the clean zone. No meaningful differences were detected between the general zone and the low clean zone, but the clean zone had significantly lower concentrations than the other zones. Additionally, the identification of the fungi was performed according to morphological method using a giant culture and slide culture. The fungi were identified as belonging to 18 genera, and the genera Cladosporium(33%), Penicillium(29%) and Aspergillus(26%), predominated. Aspergillus isolates were identified to species level, and A. ochraceus, a mycotoxigenic species, was identified. As part of the effort to control the quality of the indoor air of food manufacturing plants, our results show that continued studies are clearly warranted.

This study surveyed and compared the temperatures established in display stands and food surfaces for cold and frozen foods in large discount stores in Korea. The temperatures established in display stands for cold food ranged with 3.5 ± 1.8 ℃ as mean, minimum and maximum were 0 ℃ and 7 ℃ . However, the surface temperatures of cold food on sale ranged with 10.7 ± 2.9 ℃ as a mean, minimum 4.6 ℃ and maximum 18.4 ℃ . Totally, the surface temperature of cold food on sale was 7.2 ℃ , as a mean, higher than established in display stands for cold food in large discount stores in Korea. 53% of the surveyed cold foods were more than 10 ℃ in surface temperature and only 47% was less than 10 ℃ . The differences between temperatures were lowest in fruits, salads and vegetables, but highest in milk products. On the other hand, the temperatures established in display stands for frozen food showed a range with −20.7 ± 1 ℃ as a mean. However, the surface temperatures of frozen food on sale showed a range with −15.4 ±5 ℃ as a mean, minimum −28 ℃ and maximum −4.6 ℃ (included defrosting). The surface temperatures of frozen food,frozen meats, frozen processed foods and ice creams were −13.8 ℃ , −15.9 ℃ , and −16.8 ℃ , respectively. Only 32.3%of surveyed frozen foods showed less than −18 ℃ in surface temperature. In conclusion, the temperatures established on cold and frozen food display stands were less than those of cold and frozen food surfaces on sale. There was also much variation in food surface temperatures during cold and frozen food storage and sales. Therefore, a temperature management system technology use at the distribution level for cold and frozen foods will be developed.

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.
