This paper presents the design and automatic control methods employed to implement a open-close mechanism for a food compression processor. The automatic open-close mechanism is intended as a robust approach in compressing incoming food that posses a wide range of physical properties. The method is based on the estimation of compression pressure through current measurement. Test results show that the proposed mechanism effectively controls the compression pressure of the processed food which results in enhanced overall system robustness.

The aim of this study was to examine how customers perceive storytelling at a real local restaurant and to understand how consumption reflects their evaluation by understanding their values. Participants received information from a real local restaurant in the Gangneung area to examine the effects of storytelling and to evaluate their affective attitudes towards local restaurant stories, word-of-mouth intentions, and purchasing intentions using a seven-point Likert scale. A total of 310 consumers were used. A factor analysis was performed to identify consumption value characteristics and factor structure, which consisted economic value, emotional value, and epistemic value. To test whether local restaurant consumers could be classified into homogenous groups based on their consumption values, a three cluster solution was selected, and a Kmeans cluster analysis was performed. As a result, three groups were identified and labeled appropriate for their scores based on each of the consumption values; emotional value-oriented consumers to cluster 1, epistemic value-oriented consumers to cluster 2, and economic value-oriented consumers to cluster 3. An analysis of variance was used to examine the differences in the affective attitudes towards storytelling at the local restaurant, purchasing intentions, and word-of-mouth intentions across the three clusters. The epistemic value-oriented consumers had the highest score for all three variables. In contrast, economic value-oriented consumers had the lowest scores for the three variables. A regression analysis revealed that affective attitudes towards storytelling were significantly affected by these three consumption values. It also showed that positive affective attitudes towards storytelling were associated with higher purchasing intention and word-of-mouth. The significance of this study was to show how customers perceive storytelling at a real restaurant and reflect on their evaluation by understanding their consumption values. As a result, this study examined the potential power of storytelling as an effective marketing communication tool for local restaurants.

This study was conducted to examine the effects of a healthy dietary life and purchase of environmental-friendly food materials according to a mother's lifestyles of health and sustainability (LOHAS) attitudes. The subjects consisted of 295 mothers. The findings are summarized as follows. The mother's LOHAS attitude index averaged 3.39 points out of 5 points. High LOHAS attitude items were "I participate actively in separating the trash collection" (4.16 points), and "I recycle dresses that I do not wear by taking them to the recycling center" (4.08 points). In contrast, LOHAS attitude items for "I do community service activity on the weekend" (2.57 points), and "I try to serve in the local community" (2.63 points) scored very low. A high LOHAS behavior index occurred for mothers who were "resource saving", whereas "social welfare" scored low. Mother's intention to purchase environmental-friendly food materials averaged 3.61 points. Mother's health dietary life attitude score averaged 3.52 points. When age, monthly income, and the environmental-friendly food materials purchase ratio of the mother was high, the health dietary life performance was high. The LOHAS attitude index of mothers had an impact on the purchase intention of environmental-friendly food materials in resource saving and environmental-friendly oriented propensity groups. The LOHAS attitude index of mothers impacted healthy dietary life in environmental-friendly, family and health oriented propensity groups.

This study investigated women's magazines and women's food consumption stories of the 1950/s. That is, it attempted to comprehend the connection between the public and private aspects of food consumption as discussed in the 1950's. The public aspect of culture was investigated using the women's magazine "Yeo-won" which reflected the social and intellectual hegemony of the time. The private aspects of culture were investigated by reviewing the daily life of women though in-depth interviews. Mass media reflected the social and intellectual hegemony and indicated that a cultivated woman who supported western food was a wise mother and a good wife, and that a woman who consumed flour-based food was a reasonable and modern consumer, ahead of her time The admiration for the U.S. and its advanced civilization through free handouts of flour and powdered milk accelerated the consumption of industrialized flour-based foods such as noodles, hardtack, and steamed bread. This lead to the rigid traditional food-eating habits of boiled rice, and side dishes changed to flour-based and processed foods. That is, food represented a cultural identity.

Dry Process(natural drying, hot-air drying, oil fry drying), optimized mixture ratio and the condition of carbonization was carried out in order to improve the product durability develop eco-friendly solid fuel mixing food waste and paper sludge. As a result of the experiment, oil fry drying process was the fastest method for drying food waste and paper sludge mixture that contains 80% water inside, and the optimized mixture ratio to minimize the generating concentration of chlorine gas against caloric value of mixture ratio was 7:3. Additionally proper temperature of product carbonization was about 200℃ and shown increasing product durability through the carbonization. Therefore, the pelletized solid fuel be shaped diameter around 0.5cm, length 2cm under which was pulverized and molded using 7:3 mixture of food waste, and paper sludge was the eco-friendly solid fuel possible to be industrialized which is consist of chlorine concentration of below 2.0wt% and the lowest caloric value of over 5,000kcal/kg. In conclusion, this developing manufacturing process of the solid fuel can be interpreted to contribute alternative energy development in accordance with low carbon and green growth era.

The methods for determining the diffusion parameters for the diffusion of d-limonene, a major volatile compound of orange juice, through a multi-layered food packaging material and predicting its absorption into the packaging material have been investigated. The packaging material used was the 1.5-mm thick multi-layered packaging material composed of high impact polystyrene (HIPS), polyvinylidene chloride (PVDC), and low density polyethylene (LDPE). Orange juice was placed in a cell where volatiles were absorbed in the sample package and kept at 23±2oC for 72 hr. The d-limonene absorbed in a 1.5-mm thick multi-layered food packaging material was analyzed by a solid phase micro-extraction (SPME). The absorption parameters for the absorption of d-limonene in the packaging material were determined and absorption of d-limonene into the packaging material was predicted using absorption storage data. The SPME desorption at 60oC for 1 hr resulted in the most sensitive and reproducible results. The diffusion coefficients of d-limonene in the packaging material and the partition coefficient at 23±2oC were approximately 1-2×10-12m2/s and 0.03, respectively. The absorption profile no earlier than 30 hr was fit well by a model derived from the Fick’s law.

본 연구는 식중독을 일으키는 병원성 미생물들은 식품시료와 교차오염 원인의 지표가 될 수 있는 도마에 접종한 후 오존수와 일반 수돗물을 이용하여 세척한 후 미생물의 변화와 세척방법에 따른미생물의 변화를 각각 비교 관찰하였다. 실험결과 일반 수돗물보다 오존수가 살균효과가 더 높았고, 같은 세척수로 세척 시에도 접종 방법, 실험시료 및 시료의 표면, 균질화에 따라 살균효과가 다르게 나타나는 것을 확인할 수 있었다. 세척방법으로는 침수보다 주수 에서 살균효과가 더 컸으며 오존수의 농도는 0.2 ppm에서 유의적인 살균효과를 나타내었으며 오존수 농도가 0.4, 0.6, 1.0 ppm으로 증가함에 따라 농도 의존적으로 살균효과 또한 증가하였다. 위의 결과들을 통해 0.2 ppm 이상의 오존수가 부패 미생물 제어에 미치는 영향이 크고 식품의 제조 가공 시 여러 안전성 면에 있어서 오존수를 이용한 세척이 효과적이라고 생각된다.

본 연구에서는 국민건강영양조사 1998년(제1기)부터 2008년(제4기 2차) 조사까지 총 5기의 식품섭취조사 자료를 이용하여, ‘들깻잎, 생것’, ‘들깻잎, 데친것’, ‘들깻잎, 찐것’, ‘들깻잎, 통조림’의 섭취자 및 섭취량에 대한 분석을 시행하였다. 특히, 국민건강영양조사의 식품 섭취량 자료로부터 합리적이고 객관적으로 들깻잎 섭취자의 수 및 섭취량을 산출할 수 있는 방법을 개발하였다. 들깻잎의 섭취량에 대한 분석은 국민건강영양조사의 전체 응답자의 평균 섭취량(응답자 평균 섭취량), 들깻잎 섭취자의 평균 섭취량(섭취자 평균 섭취량), 상위 5%의 극단 섭취자의 평균 섭취량(극단 섭취량), 남성 및 여성의 평균 섭취량, 20세 미만과 20세 이상의 평균 섭취량의 5가지의 항목으로 구분하여 분석되었다. 들깻잎 섭취자의 수 및 섭취량을 분석한 결과 들깻잎 섭취자의 수는 조사연도별로 균일한 분포를 나타내었으며, 1일 7-10명 중 1명이 들깻잎을 섭취한다는 결과를 도출하였다. 남성과 여성의 섭취자 비율은 여성이 남성에 비해 평균 1.22배 더 많았다. 응답자 평균 섭취량은 2.20 g이었으며, 섭취자의 평균 섭취량은 2005년에서 가장 높았고(21.40 g), 1998년과 2008년에 비하여 0.24 g 정도 증가하였다. 대부분의 조사연도에서 남성의 섭취량이 여성에 비해 높았고, 20세 미만의 섭취량은 전체적으로 20세 이상 섭취량보다 낮았다. 극단 섭취량 1998년에서 2005년까지의 섭취량이 평균 78.02 g으로 높았지만, 2007년과 2008년에는 평균 55.58 g로 낮아졌다. 들깻잎 섭취형태를 분석한 결과 ‘들깻잎, 생것’, ‘들깻잎, 통조림’, ‘들깻잎, 데친것’, ‘들깻잎, 찐것’ 순으로 응답자 수 및 섭취량 순위가 결정되었다. 그 중 ‘들깻잎, 데친것’, ‘들깻잎, 찐것’의 데이터가 충분치 않아 결과가 좋지 않게 나왔다. 또한 국민건강영양조사 식품 섭취량 데이터는 2007년부터 상시 조사를 시작하였으며, 그 이전에는 시행된 연도에 따라 조사 기간 및 계절이 1998년과 2001년에는 11-12월, 2005년에는 4-6월로 일관되지 않았기 때문에 연간 일일 섭취량을 판단하는 데 한계가 있을 것이라 생각된다. 본 연구의 결과를 확대하면 들깻잎 이외의 다른 농산물, 축산물, 수산물 및 이들의 가공품에도 적용할 수 있다. 이러한 식품의 섭취량에 대한 객관적인 정보는 농축수산물 및 가공식품을 통해 의도 또는 비의도적으로 섭취하는 화학 잔류물질의 위해성 평가를 위한 좋은 기초 자료가 될 것이다.

The purpose of this study was to investigate the effects of perceived price and servicescape on employee service quality, food and beverage quality, and customer value in Daegu Korean restaurants and to suggest methods for them to become the food mecca of Korea and the world. The samples for this study were customers of nine Korean restaurants in Daegu. A total of 368 questionnaires were analyzed with factor analysis, a reliability test, and a covariance structural analysis. The results showed that perceived price was positively related to employee service quality and food and beverage quality and that servicescape was positively related to employee service quality and food and beverage quality. However perceived price, servicescape, employee service quality, and food and beverage quality were not related to customer value. The reasons were that these factors did not influence perceived customer value in Daegu Korean restaurants. The Daegu municipal office should require these restaurants to develop distinguished employee service and food and beverage quality and conduct consistent marketing to Koreans and westerners, so that these restaurants can become the food mecca of Korea and the world.

Changes in social, economical, and cultural environments affect the meal practices of children. The transmission of traditional Korean food culture is very important because it presents not only a well-balanced diet but also contributes to shaping identity. The purpose of this study was to investigate elementary school students' present meal practices and views, as well as demands on traditional food culture education to reflect future educational plans. Half of the students ate breakfast everyday and 72% ate a traditional Korean style breakfast. About 38% of the students participated 2-4 times per week in meal preparation and 34% participated in clean-up after the meal once a day. Although 6th graders had greater skills in basic cooking, they tended to be more passive upon applying their skills in daily meal practice. For traditional food culture education, 89% of the experienced and 86.2% of the inexperienced groups agreed on the necessity of traditional food culture education. Students attained traditional food culture knowledge through Silgwa, practical coursework within the curriculum, and by teachers leading classes. They were also educated by parents, mass media, and books outside of school. The preferred methods of class teaching were lecture and experiential learning. The preferred subjects to learn were 'cooking classes based on taste development', 'learning food ingredients through vegetable growing', 'traditional Korean food manners', and 'traditional Korean food culture and seasonal foods' as well as nutritional education. Fifth graders had more positive attitudes towards meal practices and traditional food culture education. Traditional Korean food culture and nutrition education should be integrated and developed into regular subject curricula to improve children's meal practice and inheritance of traditional food culture.

This study was conducted to examine the effect of globalization of Korean food according to well-being value perception and the foreign visitor Korean food experience. An analysis of variance and a linear regression analysis were conducted to analyze the hypotheses. The findings are summarized as follows: (1) The most important quality when eating Korean food was "taste" (37.3%). (2) The most important well-being value recognition items for Korean food were "kimchi" and "bulgogi". "Bibimbap is well-being food" (3.82 points) and "Korean food is healthy because it consists mainly of cereals and vegetables" (3.56 points). (3) The subjects highly recognized the "improvement in service quality of Korean restaurants" (3.59 points) with regard to the importance of a globalization strategy for Korean food. (4) High-intake Korean foods were "bibimbap", "baechookimchi", "galbigui", "pajeon", and "bulgogi", in that order. In contrast, the intake frequency for "songpeon", "sikhei", and "guksu" was very low. (5) The subjects thought that the globalization possibility for Korean food was high, as foreigners ingested a lot of baechookimchi. (6) The most effective well-being value recognition item for globalizing Korean food was "Korean food is nutritious and good for the health" followed by "I have much interest in Korean well-being food". and "Korean food is a well-being food because it contains many fermented and seasonal items", in that order. (7) The most effective food for globalizing Korean food with a high-intake frequency was "baechookimchi", followed by "galbigui", "guksu", and "bibimbap".
