Conventional commercial thermal process for preparing Sikhae (Rice beverage) in a hermetically sealed container was evaluated to solve the nutritional deterioration and organoleptic inferiority problem caused by severe heat treatment. A milder thermal process with an aid of Nisin, a GRAS-grade, selectively germicidal compound, was introduced to destroy the putrefactive microorganisms. In this experiment, hot-filling method with Nisin, and thermal processing (at 110$^{\circ}C$ for 15 minutes with Nisin, at 121$^{\circ}C$ for 25 minutes without Nisin) were compared. The quality of Sikhae could be enhanced and over 90% of the thermal process could be conserved by this process in terms of sterilizing value without quality deterioration when processing the bottled Sikhae at 110$^{\circ}$ for 15 minutes $\{(F^{10}{_{121})_{process}=1.54\}$.

Organizations should constantly modify and refine the mechanism by which they achieve their purposes- no only by scanning the environmental change and uncertainty, but also by choosing the right strategies. As scanning largely perceived environment, the management need to maintain a systemized perspective on their environment in order to make profitable decisions(strategic choice). Accordingly, this article presents a theoretical framework that top managers or managers of food service organizations can use to analyze their environment as an integrated and systemized whole - a model that take into account the interrelationships among domains of environment and strategic choice. Also, the results of this study will be a guideline for further expanded environmental scanning.

As the economy grows rapidly and the national income level increases, the service industry has become more important and its size gets larger. Especially, the food industry undertakes a continuing growth of consumer expenditures through no nationalization of food, consumers varying patterns of eating out, and individualization. However, it includes many problems with improving service quality towards customers owing to the absence of systems and philosophy to realize customer satisfaction management. Therefore, this study conducted a study with Korean traditional restaurant customers to measure their perceived service quality, to verify what factors most influence consumer satisfaction, and to suggest ways to meet the costumer needs by integrating the study results and developing high service quality.

The present study was conducted to investigate the effects of beverages containing fermented Akebia quinata extracts on alcoholic hangover. For this study, 25 healthy young men were recruited. All participants consumed 100 mL of water (placebo), commercial hangover beverage A or B, fermented A. quinata leaf (AQL) or fruit (AQF) extract before alcohol consumption. After 1 h, all participants consumed a bottle of Soju, Korean distilled liquor (360 mL), containing 20% alcohol. Blood was collected at 0 h, 1 h, 3 h, and 5 h after alcohol consumption. The plasma alanine transaminase (ALT) activity was highest in the placebo group. Compared with the control group, the AQL and AQF groups showed decreased ALT activity at 5 h after alcohol consumption. Plasma ethanol concentration was increased after alcohol intake and peaked at 3 h after alcohol consumption. Compared with the control group, the A group showed a higher plasma ethanol concentration at 1 h (P<0.05). At 3 h after alcohol consumption, the AQF group showed the lowest mean plasma ethanol concentration compared to the other groups; however, there were no statistical differences. After 5 h of alcohol consumption, the AQL and AQF groups showed lower plasma ethanol concentrations compared with the B group. The sensory evaluation score for the fermented A. quinata fruit extract was lower than for the commercial hangover beverages. In conclusion, the present intervention study results suggest that fermented A. quinata extracts alleviate alcoholic hangover and reduce plasma ethanol concentrations.

The purpose of this study was to investigate the snack and beverage intake patterns of students by body mass index groups (BMI <18.5, 18.5-23, 23-30, ${\geq}$30). Questionnaires were completed by 1381 high school students in Seoul, Incheon, and Gyeonggi-do, the area of Korea's capital region. There were no significant differences in skipping meals for overweight (BMI 23-30 and ${\geq}$30) or under-nourished (BMI <18.5) students. Girls skipped dinner more frequently than boys. Boys and girls both preferred meat and disliked fish regardless of BMI. Girls with BMI 23-30 disliked vegetables. Boys and girls would rather have crackers, candies, and chocolates than potatoes as snacks regardless of BMI. Obese boys (BMI ${\geq}$30) preferred flour-based food, fast food, and other food as snacks. Girls liked fruits more than boys. Snacks were eaten 2-3 times per week, when students were hungry or bored. There were no significant differences in the frequency or reasons (habitual, stressed) for snack consumption by BMI. Girls liked juice more than boys did, and boys preferred soda water more than girls did. Both the under-nourished (BMI <18.5) boy and girl groups had more juice than the overweight (BMI 23-30 and ${\geq}$30) groups. Obese (BMI ${\geq}$30) boys did not more drink soda water than other BMI groups. The under-nourished (BMI <18.5) boy group had more soda water than the normal (BMI 18.5-23) and overweight (BMI 23-30) groups. Girls in the overweight (BMI 23-30) group had 2 more cups of soda water a day than the normal group (BMI 18.5-23). Therefore, skipping meals and beverage intake patterns might influence BMI.

본 연구는 감마선 조사된 분말수정과의 저장 중 관능적 품질특성 변화 및 돌연변이원성을 평가하고자 실시되었다. 미생물 분석결과 멸균을 위한 최소선량은 약 4.5 kGy인 것으로 확인되었다. 감마선 조사된 시료들의 관능평가를 실시한 결과 조사선량이 증가할수록 모든 평가항목에 감소하는 경향이었으며, 색도의 변화를 평가한 결과 감마선 조사선량이 증가함에 따라 명도($L^*$)는 유의적으로 증가하고 적색도($a^*$) 및 황색도($b^*$)는 유의적으로 낮아지는 경향을 나타내었다. S. typhimurium TA98, TA100을 이용한 돌연변이원성 실험에서 감마선 조사군의 전 용량단계에서 음성대조군과 동일한 수준의 돌연변이 집락수를 보여 돌연변이 유발성이 없는 것으로 나타났다.
