우리나라 전통 술인 탁주와 약주를 2단 담금 방법으로 제조하였을 때 발효 단계별 미생물 균총의 변화를 조사하기 위하여 탁 약주 제조 과정 중의 미생물 균수, pH, 적정산도, 알콜 함량의 변화를 측정하였고, 담금 단계별 시료의 미생물을 분리, 동정하였다. 탁주의 2단 담금 발효초기에는 젖산균수와 효모균 수가 모두 $10^{8}\;CFU/mL$로 수준이었으나, 발효말기로 가면서 젖산균수는 $8.3{\times}10^{8}\;CFU/mL$, 효모균수는 $3.2{\times}10^{8}\;CFU/mL$로 측정되었고, 약주의 경우 2단 담금 발효초기에 젖산균수와 효모 균수가 모두 $10^{6}\;CFU/mL$로 수준이었으나, 발효말기에는 젖산 균수는 $1.0{\times}10^{4}\;CFU/mL$, 효모균수는 $1.7{\times}10^{7}\;CFU/mL$로 측정되었다. 탁 약주의 제조과정 중 미생물 균총변화는 1차적인 간이동정을 통하여 분류한 결과, 탁주의 2단 담금에서 발효 초기에 micrococci로 추정되는 세균이 80% 이었고 효모가 20% 차지하였으나, 발효발기에는 세균이 35% 그리고 효모가 65%를 차지하고 있었다. 약주의 2단 담금에서는 효모가 발효초기부터 발효말기까지 88%를 차지하고 있었다. API 20 C AUX 효모동정 kit을 이용하여 분리된 모든 효모 균주들을 동정한 결과 탁주와 약주 모두 Saccharomyces cerevisiae가 주점종을 이루고 있었고, 약 탁주의 모든 발효과정에서 Candida magnoliae가 계속적으로 발견되었다.

This study was conducted to figure the usage status and satisfaction of food-related smartphone applications by generic characteristics and food purchase attributes of Seoul area workers. The results show that health vitality-oriented group, married compared to single, those with higher eating-out expenses possess more food-related applications (p<0.05). The primary reason for the usage of food-related applications was the need for food-related information (53.7%). The highest application subjects in use were restaurant-related information and recipe information. The real-life aid food-related applications utilized most were also restaurant information (60.7%) and recipe information (28.3%). Health vitality-oriented respondents especially turned out to use nutrition information and food functionality information often (p<0.01), and recipes or calories & diet information usage frequency was higher in women than in men (p<0.001). Restaurant-related information were more frequently used by singles, highly educated, and those with high income and eating-out expenses (p<0.05). Satisfaction of food-related applications was normal (3.06), showing that the satisfactory level is not yet high. Satisfaction regarding purchase attributes showed that the health vitality-oriented group (3.19) was more satisfied compared to other groups (p<0.05), and women (3.16) were more satisfied that men (2.89) were (p<0.05). Inconveniences of food-related applications were highest in usage fee (3.29), simplicity of information (3.28), lack of reliability of information and need for update (3.10). The results of this study implies that various subdivisions of food-related applications users should be implemented; at the same time, food-related applications covering diverse subjects that regard each group's characteristics should be developed in order to utilize food-related knowledge and information as a marketing tool in the food industry; this can efficiently be done by paying attention to the quality of information and updates within applications.

떡과 한과는 수백 년 전부터 우리 식생활 전반에 걸쳐서 밀접한 관계를 가지고 있다. 슬플 때나, 기쁠 때나, 정을 나눌 때나 언제나 떡과 한과는 우리와 함께 해 왔다. 건강에 대한 관심이 고조되면서 세계의 많은 사람들이 한국음식에 관심을 갖기 시작하였다. 이에 따라 우리의 떡과 한과에 대한 관심도 높아져 신세대와 외국인 등 우리 떡에 대한 새로운 변화를 기대하는 사람들이 매우 급증하는 추세이다. 서양의 피자, 케이크, 빵류가 우리의 생활에 침투하였듯이 우리의 떡과 한과도 좀 더 연구 개발에 힘쓴다면, 서양의 문화에 자연스럽게 침투하여 세계인의 생활 속에 친숙한 음식문화도 자리 잡을 수 있을 것이다.

The purpose of this study was to investigate the perception and preference of 'Jook' among people to find the effective way of promoting consumption of Korean traditional 'Jook'. This survey was conducted in Seoul, Suwon, Pyongtaek area. Among 450 questionnaires, 363 responses were collected and were analyzed by SAS program. The results were as follows: 47% was male,33.1% were 20 to 29 years old and 45% were students. Age and sex were main factors influencing the perception and preference of 'Jook' Older generation and women liked 'Jook' the most. 'Potjook', 'Hobakjook', 'Dakjook', 'Hinjook' were mostly preferred in order. 'Jook' was eaten because of 'easy to digest', 'special treat', 'convenience food', and 'therapeutic purpose'. But taste was the most preferred characteristics selecting 'Jook' except 'Hinjook'. In developing 'Jook' to be consumed, diversity and convenience should be placed in the first priority.

Mevinolin, a fungal metabolite, is a potent inhibitor of 3-hydroxy-methyl-3-glutaryl-coenzyme A (HMG-CoA) reductase, the rate-controlling enzyme in cholesterol biosynthesis. In this investigation, the optimum factors for mevinolin production by Monascus pilosus IFO 480 in soymeal fermentation were studied. The highest yield of mevinolin, 2.82 mg mevinolin per g dry weight, without citrinin (a toxic fungal secondary metabolite) was obtained after 21 days of fermentation at $30^{\circ}C$ at 65% moisture content, particle size 0.6-0.9 mm, and initial substrate pH of 6.0. Mevinolin was present in the fermentation substrate predominantly in the hydroxycarboxylate form (open lactone, 92.1-97.3%), which is currently being used as a hypocholesterolemic agent.

Many researchers revealed that collagen contribute to maintaining the skin’s elasticity and inhibit wrinkling of skin. Korean native cattle (Hanwoo) bone (leg bone, foot and tail) infusion contains the various inorganic materials, collagen and chondroitin sulfate. All of this, a large quantity of collagen is included in Hanwoo infusion. Therefore, this study emphasized on the effects of collagen in the Hanwoo bone infusion. For the first time, Hanwoo bone infusions were directly added to the media of Human Dermal Fibroblast (NHDF-c) to test anti-aging effects. First, it was identified that growth rate of skin fibroblast was increased. Furthermore, the Hanwoo bone infusion increased a 50% of fibroblast collagen synthesis. Also, suppression of skin fibroblast aging was confirmed by treatment Hanwoo bone infusion. In conclusion, this study demonstrates the effects of infusion made from Hanwoo leg bone, foot and tail on anti-aging, wrinkle inhibiting and skin fibroblast elasticity maintaining. Therefore, this study identified that traditional infusion has effects that are good for skin elasticity.

The purpose of this study was to examine the effects of a lifestyle consisting of a health oriented diet and personal motivation toward health improvement on an individual's desire to participate in condolence or "healing" -workshops and programs. In order to examine the influence of the "health diet" and motivation, the "health diet" lifestyle was classified into nutrition pursuit factors, psychological factors, food safety factors, and health conscious consumption factors. Personal motivation was categorized into perceived benefits, environmental factors and the individual's desire for happiness. Empirical analysis showed that nutrition pursuit factors had an impact on perceived benefits and the desire for happiness. Psychological aspect factors had a significant influence on perceived benefits, environmental factors and the desire for happiness. However, food safety factors and health conscious consumption factors did not have an effect on individual motivation to improve health. Regarding personal motivation toward health improvement on the desire for "healing", perceived benefits and environmental factors had significant influence. However, the individual's desire for happiness did not influence the demand for "healing". Regarding the effect of a "health diet" on the desire for "healing", only the psychological aspects of a "health diet" had any significant effects on the desire for "healing". The results from this study can help local organizations or service companies that provide "healing" programs with developing effective marketing strategies that could lead to greater customer satisfaction. Especially, the significant influence of psychological aspects of a "health diet" on the demand for "healing" is noteworthy in that this could play a key role in establishing a more effective marketing strategy to attract increasing numbers of consumers using health conscious diets.

전통안동식혜를 제조하여 20일 동안 저장하여 그 숙성 및 저장기간 동안 여러가지 화학적 변화에 관하여 실험하였다. 숙성기간 동안 조지방 및 수분의 함량변화는 거의 없었으나 조단백질의 함량은 차차 감소하였다. pH는 숙성 3일경에 4.36이었으며 그 후 차차 감소하여 저장 20일에는 3.90이었다. 유리당의 조성은 maltose를 포함하여 4종류가 검출되었으며 maltose의 함량은 차차 증가하여 저장 15일에는 유리당 가운데 76%를 차지하였다. 아미노태질소는 숙성 3일에 22.40mg% 차지하였으며 이때가 식혜의 맛이 가장 좋았다. 유리아미노산에 있어서는 proline 및 aspartic acid의 함량이 숙성 3일째에 각각 115.2, 28.9mg으로 가장 많았고 수용성 및 염용해성 단백질의 아미노산 조성은 glutamic acid와 aspartic acid의 함량이 가장 많았다.
