Osteoporosis is recognized as one of the major hormonal deficiency diseases, especially in menopausal women and the elderly. When the estrogen level is reduced in the body, local factors, which are known to be related with bone resorption, are increased and promote osteoclastogenesis. In our previous study, we validated the estrogenicity of silkworm pupa. In this study, we investigated the effect of silkworm pupa extract (SPE) on the function of osteoblastic MC3T3-E1 cells. SPE (10 and $50\;{\mu}g/mL$) significantly elevated cell viability, alkaline phosphatase (ALP) activity, and collagen content in the cells. The effect of SPE ($50\;{\mu}g/mL$) in increasing cell viability, ALP activity, and collagen content was completely inhibited by the presence of $10^{-6}\;M$ of cycloheximide and $10^{-6}\;M$ of tamoxifen, suggesting that SPE's effect results from a newly synthesized, protein component and that it might be partly involved in estrogen action. Furthermore, we examined the effect of SPE on the $H_2O_2-induced$ apoptosis and production of local factors in osteoblasts. Treatment with SPE ($50\;{\mu}g/mL$) decreased the 0.2 mM $H_2O_2-induced$ apoptosis and the production of tumor necrosis factor (TNF)-${\alpha}$, interleukin (IL)-6 and nitric oxide (NO) in osteoblasts. Our data indicate that the enhancement of osteoblast function by silkworm pupa may prevent osteoporosis and inflammatory bone diseases.

The purpose of this study was to investigate the product characteristics of 'Songhwasulgi,' which combines different kinds of pine pollen flours and sugars with non-glutinous, rich flour. The results of sensory evaluation indicated that the larger amount of pine pollen flour was mixed with non-glutinous rice flour higher level of bitterness, softness, and feeling after-swallowing was obtained degree of chewiness was in relation to the lesser amount of pine pollen flour. With regard to color, a higher acceptance level was achieved as the lesser amount of pine pollen flour was incorporated with non-glutinous rice How. On the other hand, it was revealed that the category of adding a honey to $7\%$ of pine pollen flour was found to be the highest level of flavor and overall quality According to the results of texture evaluation, the degree of hardness, adhesiveness, and cohesiveness decreased as the larger amount of pine pollen flour was combined with non-glutinous rice flour. It was also found that the springiness of the texture tended to be low as more pine pollen flour was added. In addition, the degrees of gumminess and chewiness was inversely related to the amount of pine pollen flour With respect to a correlation between sensory evaluation and mechanical test, it was found that Songhwasulgi with higher acceptance level for color and flavor also obtained a higher level of hardness and overall quality.

연속식 옴가열 장치를 이용한 고추장을 베이스로 한 모델 식품에 대한 가열 살균 연구를 진행하여, 옴가열을 이용한 소스 살균에 필요한 기초 데이터를 수집하였다. 옴가열 시 점도에 상관없이 $100^{\circ}C$까지 고르게 상승하였으나, 점도가 높을수록 전기전도도와 가열속도가 낮아져 살균력이 감소하는 것으로 나타나, 저점도 식품이 옴가열을 이용한 가열 및 살균에 있어 더 유용하다는 것을 알 수 있었다(13,14). 재래가열 후의 살균도는 65.4-75.4%, 옴가열 시는 89.5-95.0%로 살균력이 더 우수하였다. 향후 연속식 옴가열 장치의 살균효과를 더 높이기 위해서는 여러 개의 셀 연결 방식을 통해 한 개의 셀에서 온도를 조금씩 상승시켜 스케일 생성을 방지하는 연구와 셀 통과시 빠른 온도 상승에 의한 점도 변화로 살균 처리량이 변하기 때문에 최적 셀 조합 및 가열살균 조건에 대한 충분한 고찰이 필요할 것으로 생각된다.

As Korea has approached the aging society, older Koreans have become an important force in restaurant sales today. To succeed with this silver market, it is important for restaurant managers to know who they are and what factors influence older Koreans' eating-out decision making process. The purpose of this study was to investigate the effect of the silver consumers' education level on eating-out decision making process. Data were collected from 178 older consumers above 55 years old and analyzed using the descriptive statistic analysis, MANOVA, and one-way ANOVA. The results showed that the elderly consumers' education level significantly influenced the decision making process in determining where to eat out. Significant differences were found in the Problem Recognition Step(Wilks' Lambda=0.817, F=2.991), Information Search Step(Wilks' Lambda=0828, F=2.218), Alternative Evaluation Step II(Wilks' Lambda=0.741, F=3.596), Purchase Decision Step(Wilks' Lambda=0.859, F=2.223), and the Post-Purchase Behavior(Wilks' Lambda=0.885, F=1.780). The higher education level was, the more directly involved in the eating out decision process. The elderly consumers with university education were likely to 'propose to eat out by themselves'(F=9.346), to obtain restaurant information from the 'printed materials'(F=7.452), to go to 'family restaurant'(F=9.057), 'Japanese restaurant'(F=8.7891) and 'fine dining restaurants'(F=3.936), and to directly express their emotion when they had complaints about restaurant service(F=3.206). In conclusion, older Koreans will become more healthy and wealthy which means the dining out activity will be an important part of their life to socialize with people. Therefore, food service operations should consider the elderly consumers' needs and expectation of restaurant services and actively position themselves for this new market segment.

The fermentation of Panax ginseng yields many compounds including ginsenosides that have various biological functions. The objective of this study was to investigate the modulation of nitric oxide (NO), Interleukin (IL)-6 and tumor necrosis factor $(TNF)-{\alpha}$ in Raw 264.7 cells treated with ginseng fermented by Penibacillus MBT213. Nitric oxide production in the Raw 264.7 cells treated for 24 hours with fermented ginseng at 3, 7, and 14 days after the treatment decreased to 74, 43, and 36%, respectively, compared with the positive control. The production of IL-6 was inhibited in all the cells treated with fermented ginseng at 3, 7, and 14 days after the treatment except for the positive control. The $TNF-{\alpha}$ production in the Raw 264.7 cells treated with fermented ginseng for 6 hours at 3, 7, and 14 days after the treatment was about 40,000, 85,000 and 65,000 pg/mL, respectively. Moreover, the $TNF-{\alpha}$ production in the Raw 264.7 cells treated with fermented ginseng for 24 hours at 7 and 14 days after the treatment was about 160,000 and 180,000 pg/mL, respectively. However, $TNF-{\alpha}$ production was inhibited in the Raw 264.7 cells at 6 and 12 hours after the treatment with fermented ginseng. herefore, it was confirmed that the immunological activity of the Raw 264.7 macrophages was affected by the treatment with fermented ginseng. It was concluded that ginseng fermented by Paenibacillus MBT213 possesses a potential anti-inflammatory activity and could be used as an ingredient in functional foods and pharmaceutical products.

Local non-timber forest products can be easily accessed by tourists. These also provide opportunities for tourists to experience the local culture. Many local governments are paying constant attention to the development of non-timber forest product brands to revitalize the local economy and increase the profits of local farmers. Although there are many forest products and tourism resources in each region of Korea, there is no local specialized strategy to sell non-timber forest products and promote consumers' purchase intentions. In this study, we aimed to explore the consumers' perceived creating shared value (CSV) and its association with purchasing behavior of non-timber forest products in Jeongeup city, Korea. Data were collected from 1,066 consumers who had purchased non-timber forest products. Purchasing patterns of local specialty products differed depending on consumers' perceived CSV levels. In addition, consumers with higher levels of perceived CSV showed higher awareness and familiarity with Jeongeup city and experienced Jeongeup city's non-timber forest products. Our findings suggest that improving consumer perception towards CSV of non-timber forest products can be used as a marketing strategy for local non-timber forest products to revitalize the local economy.

The purpose of the study was to assess the relative preference for hot & spicy sauces using conjoint analysis, with focus on English consumers. From the results of the study, we were able to derive a standard with the best sauce attributes. The respondent group was selected from the CCFRA's customer database. The qualification criteria for inclusion in the sample were: the primary grocery shopper in the household, a consumer of a range of home cooked oriental & far eastern cuisines, enjoyed hot & spicy chili-based foods, and willing to buy hot chili-based oriental sauces. A total of 676 respondents completed the survey in which 76% were women, and all respondents were between the ages of 18 and 65 years. An online survey method was used and a conjoint analysis was adopted. In conjoint analysis, a product is described as a combination of a set of attribute levels, where a utility value is estimated for each attribute level. In summing up the results of this study, the sensory property (flavor) attribute was most important, the second was brand, and the third was price. For the sensory property attribute, a mild chili sauce of blended garlic, sugar, and lime scored highest. In terms of brand, Blue Dragon was selected as the best. The lesser known Korean Kochujang brand of "Hot&Joy" scored lowest with respect to brand value. Encouraging, however, was the description based on the Hot&Joy product: a hot chili sauce blended with ginger and garlic, which held appeal across age groups and genders. In terms of price, 75p per bottle had the best score.
