  • To improve antioxidant glutathione (GSH) content and saccharification ability in sake yeasts of Saccharomyces cerevisiae, the ${\gamma}$-glutamylcysteine synthetase gene (GSH1) from S. cerevisiae, glucoamylase gene (GAM1) and ${\alpha}$-amylase gene (AMY) from Debaryomyces occidentalis were co-expressed in sake yeasts for manufacturing a refreshing alcoholic beverage abundant in GSH from rice starch. The extracellular GSH content of the recombinant sake yeasts increased 1.5-fold relative to the parental wide-type strain. The saccharification ability by glucoamylase of the new yeast strain expressing both GAM1 and AMY genes was 2-fold higher than that of the yeast strain expressing only GAM1 gene when grown in the culture medium containing 2% (w/v) rice starch. It generated 11% (v/v) ethanol from 20% (w/v) rice starch and consumed up to 90% of the starch content after 7 days of fermentation.

  • Distillers dried grain (DDG) and makgeolli spent grain (MSG) are agricultural byproducts to produce alcoholic beverage. However, they are known to contain enough nutrients. Mealworm is a promising insect resource for an animal feed ingredient as well as alternative human food. With low cost, DDG and MSG were investigated as a feed ingredient for rearing high quality mealworms. DDG and MSG were mixed with wheat bran and compared to control feed (only wheat bran) for its effects on larval survivorship, larval weight, duration for developmental period, pupation rate, and pupal weight. When DDG added, larval survivorship was reduced to 50~70% compared to the control group. Larvae fed on DDG were heavier from third to sixth week. Especially, larvae with 50% DDG were 28% heavier than the control group at the third week. For the larval period, the 50% DDG group was 11% less than that for the control. The pupal weight for the 30% DDG group was 7% heavier than that for the control group. Pupation rates for all the DDG groups were higher than 90%. When compared to the control, larval survivorship for the 70% MSG group was low, but the 50% and 70% MSG groups were high during the seventh and eighth weeks because of delayed development. After the eighth week, larvae with 70% MSG showed the highest larval weight increase as 9~18% compared to the control group. Except 70% MSG group, all of MSG groups showed more than 90% pupation rates. We confirmed that adding 30~50% of DDG or MSG to conventional wheat bran have a strong potential to replace the conventional wheat bran insect feed for quality insect production.

  • It was examined the effect of fermented rice wine using mycelium of Phellinus linteus (FWPL) on the gastric mucosa of rat. The gastric mucosal lesions were not seen macroscopically in normal, but ethanol-administrated rats produced congestion and edema with a few local lesions. The administration of FWPL showed a similar pattern as like normal except trace histopathological changes. The results of Western blot analyses showed that the higher expression of inducible nitric oxygenase (iNOS), cyclooxygenase (COX)-1, COX-2, tumor necrosis factor-$\alpha$ and c-fos, especially COX-2, in the ethanol-administrated rat compared with normal rat. But FWPL-administrated rat showed a trace increase of these expression compared to normal rat. About immunohistochemical observations, weaker iNOS reactions were detected in mucous cells of epithelim of ethanol administrated rat compared with normal and FWPL-administrated rat. These results suggested that FWPL-administrated rat showed a trace changes on the mucus barrier-related protein expression compared with ethanol-administrated rat and thus FWPL may be use to develop a functional alcoholic beverage.

  • It was examined that the effect of fermented traditional wine made by using mycelium of Phellinus linteus on the expression of inflammation-related proteins in HepG2 cells. HepG2 cells were incubated with or without ertract of traditional wine (ETMP), then analyzed by microscopic observation, reverse transcription polymerase chain reaction (RT-PCR) and Western blot. The results of RT-PCR and Western blot analyses showed that the level of inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 and tumor necrosis factor $(TNF)-{\alpha}$ was induced by LPS, Dut the treatment of ETMP inhibited the expression of these proteins and its mRNAs. Besides, the results of Western blot analyses showed that the expression of nuclear $factor-{\kappa}Bp65$ and $inhibitory-{\kappa}B{\alpha}$ were also slightly affected by ETMP treatment. These results suggest that ETM P alleviate the expression of inflammation-related protein expressions and thus may be used as a functional alcoholic beverage.

  • Purpose: Previous studies have highlighted that the nutritional behaviors among South Korean workers are far from ideal. This study examined the organizational influences affecting the eating practices of office workers in South Korea. Methods: We conducted in-depth interviews with 22 office workers at 12 companies in South Korea. The interviewer inquired about the employees' daily routines on food and beverage intake. The various factors that influence their food choices in their work environments were also explored. The interviews were transcribed and then analyzed using a content analysis. Results: A framework analysis revealed 7 key recurring themes, and these were grouped under three levels: team-, company-, and corporate group-levels. First, team dinners are core social events for all the workers and they tend to include high-caloric food and alcoholic beverages. The frequency of team meals and the food associated with them depend on various team characteristics such as gender composition, the nature of a team's work and the team leaders' emphasis on group meals. Second, the company's policies and practices regarding budget allocation for team meals and subsidies for cafeteria meals affect the workers' food intake practices. In addition, the physical environment of the worksite cafeterias can influence the choices of foods. Third, various corporate group policies that were not designed to target food intake had additional positive effects on the workers' eating behaviors. Conclusion: This study provides important insights into the broader organizational influences on the food consumption of employees in their workplace. These insights can be used to design and implement more effective intervention strategies for improving the nutritional behaviors of office workers.

  • This study reviewed critically the music regulations of broadcasting advertising and analyzed the post reviews of Korea Communications Standards Commission(KCSC) to find their problems and suggest alternatives for their improvements. As general core regulations, lyrics changes of children's song is banned except in non-commercial public advertising and lyrics changes to folk songs are permitted unless it includes the product related expressions, such as brand name; both of their arrangements are permitted. According to the items, the lyrics of the CM song of drug advertising should not include its brand name; alcoholic beverage advertising is banned if the lyrics of the CM song include product-related brand name or an expression encouraging drinking. The rationales of these regulations of restrictions or prohibitions of music in broadcasting advertising are unclear and are insufficient. Therefore, it will be necessary to improve them based on the evidence or knowledge by more valid research in the future.

  • An exploratory study was conducted in Gopalganj, a southern district of Bangladesh to explore the role of wild date palm (Phoenix sylvestris Roxb.) husbandry in the rural economy. A total of 36 households in the study area were interviewed using a semi-structured questionnaire. A multistage sampling method with 10% intensity and a semi-structured questionnaire were used for the study. Based on the land holding capacity of the households, the farmers were categorized into five groups as landless, marginal, small, medium, and large. The date palm was distributed over seven different habitats of which roadside support the highest value (31%) followed by agricultural field and orchard (25% each). Though the large category farmers own most of the palms (43%), a considerable portion (562 individuals out of 1980) of it is managed by the landless farmers, who earn a substantial livelihood from the palms. The farmers manage the palm mainly for juice production; juice is either used fresh as drink or after some sort of processing as molasses and/or alcoholic beverage. Date palm husbandry contributes 32,601 Tk., 21,107 Tk., 20,626 Tk., 29,574 Tk. and 35,335 Tk. respectively to the five group seasonally and 50,980 Tk., 77,556 Tk., 90,208 Tk., 112,560 Tk., 140,675 Tk. respectively annually (1 US$ = 70 Tk.). Date palm trees contribute 65.48% of mean annual income to landless farmers followed by 27.21% to marginal farmers. However the poor marketing system result in decreasing the annual return from palm trees. Palm husbandry could be a promising source of rural incomes in Bangladesh if the farmers' traditional management knowledge was linked to more scientific management practices.

  • Yeasts play an important role in spontaneous fermentation of traditional alcoholic beverages. Our previous study revealed that a mixed-consortia of both Saccharomyces and non-Saccharomyces yeasts were responsible for fermentation of khadi, a popular, non-standardized traditional beverage with an immense potential for commercialization in Botswana. Functional characterization of isolated fermenting yeasts from mixed consortia is an indispensable step towards the selection of potential starter cultures for commercialization of khadi. In this study, we report the characterization of 13 khadi isolates for the presence of brewing-relevant phenotypes such as their fermentative capacity, ability to utilize a range of carbon sources and their ability to withstand brewing-associated stresses, as a principal step towards selection of starter cultures. Khadi isolates such as Saccharomyces cerevisiae, Saccharomycodes ludwigii and Candida ethanolica showed good brewing credentials but Lachancea fermentati emerged as the isolate with the best brewing attributes with a potential as a starter culture. However, we were then prompted to investigate the potential of L. fermentati to influence the fruity aromatic flavor, characteristic of khadi. The aroma components of 18 khadi samples were extracted using headspace solid phase micro-extraction (HS-SPME) and identified using a GC-MS. We detected esters as the majority of volatile compounds in khadi, typical of the aromatic signature of both khadi and L. fermentati associated fermentations. This work shows that L. fermentati has potential for commercial production of khadi.

  • The purpose of this study is to review the theories and cases of performance sharing in the franchise industry to present a method for more effective franchise performance-sharing. To that end, this study reviewed the theory on resource dependence and the theory on inequality to describe the performance-sharing between the franchisor and the franchisee and their relationship. It also looked at the cases of a week-in cooler system at 'Beer Market', the allocation of fees for alcoholic beverage sales to franchisees, the scholarship program of 'Onigiri and Ikyudon' and 'Bonsamo' which is a franchisees' committee for Bonjuk to introduce examples of performance-sharing. Through a theoretical review and case review, this study presents five types of methods for performance-sharing. First, 'the sharing of core competence by the franchise company; second, 'the establishment of a royalty culture'; third, 'scientific analysis of markets and establishment of a revenue forecast system'; fourth, 'reinforced financial support from the franchisor'; and lastly, 'the positive application of franchisees' committees'. Such methods are expected to provide a groundwork for mutual benefit and co-prosperity between franchisor and franchisee.

  • The purpose of this research was to investigate consumers' perceptions of foods that are most compatible with traditional Korean liquors. The study participants were a total of 402 customers who visited traditional Korean bars. Thirty-eight percent of the participants drank alcohol once or twice a week, and overall, 79% drank with friends or co-workers. Forty-three percent spent 30,000-40,000 won on alcoholic drinks, and half of them frequently drank distilled Soju whereas 27% drank beer. Those who drank traditional Korean liquor chose to do so because they viewed it as good for their health and the beverage was tasty. Participants selected Yakju/Baekseju (47.5%), Bokbunjaju (21.1%), and Takju/Makgeoli (8.2%) as the most compatible Korean traditional liquors with Korean traditional foods. The most compatible foods with Yakju were identified as Haemulpajeon (11.8%), Dubukimchi (9.8%), and Bossam/Suyuk/Pyeonyuk (7.5%). Bokbunjaju was viewed as a good match with Jangeogui (8.1%), Hunjeori (6.5%), and Saengseonhoe (6.4%). The respondents perceived Deodeokgui (6.7%), Saengseonhoe (5.9%), and Dubukimchi (5.6%) as the most compatible foods with Yakju with mushrooms. Chengju was viewed as a good pairing with Eomuktang (9.2%), Altang/Maeuntang (7.2%), and Saengseonhoe (6.8%). The respondents thought Takju went well with Haemulpajeon (17.7%), Dubukimchi (14.2%), and Kimchijeon (11.7%). And finally, Altang/Maeuntang (11.8%), Samgyeopsalgui (8.7%), and Honghaptang/Jogaetang (8.1%) were mentioned as the most compatible foods with distilled Soju.
