In this study, to prove the effect of soybeans's electron donating ability and its addition on eel gouem, storage and sensory characteristics were examined. During the storage period, pH values of all gouem samples were decreased with initial increase except the control. BSB $3\%$ sample had the lowest pH value and YSB $10\%$ sample was the highest 6.71 in pH value at first storage day. The electron donating ability of soybeans were increased with the amount of addition. The electron donating ability of SBSB 20g sample was the highest, which was 2 ${\~}$ 3 times higher than that of YSB sample. L values of all the gouem samples had a tendency to decrease according to the storage period and amount of addition. All samples' a values were increased throughout the storage period, while b values decreased except the control and GNG sample. TBA and VBN values of all the samples were up and down throughout the storage period SBSB $10\%$ sample had the lowest in TBA value. The electron donating ability of all soybean samples and TBA value of eel gouem samples showed a negative correlation. Total plate count of bacteria was increased rapidly for initial storage period, but all samples showed a tendency of slow growth after the 8th day of storage. During all storage days, SBSB, BSB samples had a similar tendency of low total plate count growth. GNG $10\%$ sample showed the lowest in total plate count of bacteria at sixteenth day of storage. Sensory scores of all samples decreased with storage. For all the items of the sensory evaluation, SBSB $5\%$ sample got the highest score among all eel gouem samples. GNGSB sample showed the lowest in TBA value and total plate count of bacteria. And in the sensory evaluation, GNGSB sample got the highest scores for several items.

Microbial contamination of ready-to-eat ingredients for Kimbab manufacturing and the effect of irradiation to reduce the microbial contamination of the products were investigated. Among 9 food items tested, there were no viable cells in the ham, seasoned and cooked beef, imitation crab leg, fried egg, and seasoned burdoc. Cucumber, surimi gel, and seasoned and blanched spinach were counted at 5.07$\pm$0.97, 3.50$\pm$0.14, and 5.41$\pm$0.51 log CFU/g, respectively. Irradiation at 1 kGy reduced the number of microorganism in these ready-to-eat foods to an undetectable level. However, the dried laver showed an 8.83$\pm$0.10 log CFU/g and an irradiation at 3 kGy reduced the level to only 7.14$\pm$0.23. Sensory evaluation of the irradiated Kimbab prepared from these food materials indicated that the measure of the control of the sensorial quality should be provided before applying an irradiation to the prepared Kimbab.

Purpose : The purpose of this study was to examine the effects of short neck flexor strengthening in proprioceptive neuromuscular facilitation and neuromuscular electrical stimulation on swallowing function in patients with chronic stroke and to provide basic data for swallowing rehabilitation in stroke patients. Method : The study involved 30 chronic stroke patients who visited ${\bigcirc}{\bigcirc}$ General Hospital in Daegu Metropolitan City between March and July, 2017. The subjects were randomly assigned to either an experimental group (n=15) or a control group (n=15). Both groups underwent traditional swallowing rehabilitation therapy for 30 minutes five times a week over a six-week period. The experimental group performed short neck flexor exercises, which are part of the proprioceptive neuromuscular facilitation, for 30 minutes three times a week over a six-week period. The control group performed neuromuscular electrical stimulation for 30 minutes three times a week over a six-week period. Based on its results, changes in the patients' swallowing function and degree of food intake were analyzed. Result : In terms of the ASHA NOMS scale and new VFSS scale, the experimental group and the control group showed statistically significant changes in ten sub-items and six sub-items, respectively. Statistically significant differences in one sub-item were found between the groups. Conclusion : PNF-based short neck flexion exercise appear to be effective at improving swallowing function of stroke patients with dysphagia.

The prevalence of obesity is continuing to increase. Self-perceived body image among women has drawn a lot of attention in Korea due to unhealthy weight control trials. This study was conducted to determine the relationship between self-perceived body image and dietary intakes among Korean women. For the analysis, 1,747 subjects were selected after eliminating those who were likely to have recently altered their diet based on the 2010 Korea National Health and Nutrition Examination Survey (KNHANES) data. The subjects were divided into three groups: underweight, normal, and obese groups according to their perception of body image. Daily nutrient intakes, NAR (Nutrient Adequacy Ratio), and food intake frequency were assessed according to age group and body image perception. Only energy intake showed differences among the three body image perception groups across all age groups, but not statistical differences. Analysis of NAR and the order of most frequently consumed food items confirmed these findings. The ratio of underweight women that perceived their body size as normal or overweight was higher with younger age. Incorrect body image perception and unhealthy weight control behaviors can cause nutritional problems. This study confirmed that nutritional knowledge is important for healthy weight control trials. Nutritional education for healthy dieting should be emphasized among Korean women.

Many people reported suspected food poisoning after consuming food at the same snack bar on June 18, 2020. Thus, an in-depth epidemiological investigation was conducted to identify the infectious agent and establish additional food poisoning prevention measures. The study included people who reported to the local public health center after June 18 with acute gastroenteritis symptoms within 4 days of consuming food from the snack bar. The onset of symptoms and food items consumed by individuals were then investigated via phone calls and on-site visits. Afterward, the infectious agent was identified from human samples (stool or rectal swab) of four restaurant employees and 89 people and from environmental samples (materials, cooking utensils, and water). The analysis revealed that the incubation period ranged from 2 hours to 92 hours, with a median and mode of 16 hours and 12 hours, respectively. Moreover, the epidemic curve had a unimodal shape because of common exposure, which reached its peak on June 18. After monitoring for 8 days, which is more than twice the maximum incubation period of 92 hours, the end of the epidemic was declared on June 28 as no additional cases were reported. Analysis of human and environmental samples revealed Salmonella bareilly of the pulsed-field gel electrophoresis pulsotype SAPX01.017 as the causative agent. Therefore, it was concluded that the food poisoning outbreak was caused by S. bareilly.

임신성 당뇨병의 발병에 영향을 미치는 식이 인자를 알아보고자 컴퓨터용 식품섭취 빈도조사지와 설문지 등을 이용하여 임신성 당뇨병의 환자군-대조군 연구를 시행한 결과는 다음과 같다. 임신성 당뇨병군이 대조군보다 연령과 BMI가 높았고, 당뇨병의 가족력이 많았다. 임신전의 식습관은 임신성 당뇨병군이 대조군보다 1일 식사횟수가 적었고, 식사시간이 불규칙하고 식사속도가 빨랐으며 채식을 적게 하고 기름진 음식을 싫어하는 경향이었으며, 식습관점수가 낮았다. 식품섭취빈도법으로 조사한 영양소 섭취량에서는 임신성당뇨병군이 대조군보다 탄수화물의 섭취량이 유의적으로 많았고 단백질의 에너지 섭취비율이 유의적으로 낮았다. 지방의 섭취량에는 두 군간에 차이가 없었으며 임신성 당뇨병군이 대조군보다 단백질과 칼슘, 인, 비타민 B,의 영양밀도가 유의적으로 낮았다. 두 그룹간에 섭취량에 유의적 차이를 보이는 식품 중 쌀, 중국국수, 돼지고기 등은 임신성 당뇨병군에서 대조군보다 많이 섭취하였고, 옥수수, 오징어채, 큰멸치, 수박, 포도, 복숭아, 밤, 땅콩, 호상 요구르트, 치즈, 검정콩, 당근 등은 대조군에서 섭취량이나 섭취빈도가 많았다. 두 군 사이에 섭취량에 유의적 차이를 보이는 음식 중 온면, 시루떡, 햄버거, 돼지고기편육, 삶은 계란 등은 임신성 당뇨병군에서 섭취량이 많았고, 전병, 두부조림, 오징어채무침, 깍두기, 야채샐러드, 김치국, 과일샐러드, 콩밥, 콩조림, 토마토쥬스 등은 대조군에서 섭취량이나 섭취빈도가 많았다. 특히 쌀의 경우에는 임신성 당뇨병군이 대조군보다 섭취량은 많았으나 섭취빈도는 적어 임신성 당뇨병군에서 1회의 섭취분량이 많았던 것으로 생각할 수 있다. 영양소 중에서는 탄수화물이나 에너지의 섭취량이 많을 때 임신성 당뇨병의 odds ratio가 증가하였고, 식품이나 음식은 쌀, 국수, 돼지고기, 온면, 시루떡, 햄버거, 삶은 계란, 돼지고기편육 등의 섭취량이 많을 때 임신성 당뇨병의 odds ratio가 증가하였다. 상관관계의 분석결과 에너지 섭취량, 탄수화물 섭취량 등이 혈액의 포도당농도와 상관관계가 있는 것으로 나타났다. 이상으로 본 연구 결과를 종합해 볼 때 임신성 당뇨병에 영향을 미치는 식이 인자는 지방보다는 탄수화물의 섭취량으로 생각되어지며 단백질을 포함한 식사의 질과 바람직하지 않은 식습관이 영향을 미칠 수 있음을 생각해 볼 수 있다.

BACKGROUND/OBJECTIVES: Use of nutrition labels in food selection is recommended for consumers. The aim of this study is to examine factors, mainly beliefs explaining nutrition label use in female college students based on the Theory of Planned Behavior (TPB). SUBJECTS/METHODS: The subjects were female college students from a university in Seoul, Korea. The survey questionnaire was composed of items examining general characteristics, nutrition label use, behavioral beliefs, normative beliefs, corresponding motivation to comply, and control beliefs. The subjects (n = 300) responded to the questionnaire by self-report, and data from 275 students were analyzed using t-test or ${\chi}^2$-test. RESULTS: The results showed that 37.8% of subjects were nutrition label users. Three out of 15 behavioral beliefs differed significantly by nutrition label use. Nutrition label users agreed more strongly on the benefits of using nutrition labels including 'comparing and selecting better foods' (P < 0.001), 'selecting healthy foods' (P < 0.05). The negative belief of 'annoying' was stronger in non-users than in users (P < 0.001). Three out of 7 sources (parents, siblings, best friend) were important in nutrition label use. Twelve out of 15 control beliefs differed significantly by nutrition label use. These included beliefs regarding constraints of using nutrition labels (e.g., time, spending money for healthy foods) and lack of nutrition knowledge (P < 0.001). Perceived confidence in understanding and applying the specifics of nutrition labels in food selection was also significantly related to nutrition label use (P < 0.001). CONCLUSIONS: This study found that the beliefs, especially control beliefs, suggested in the TPB were important in explaining nutrition label use. To promote nutrition label use, nutrition education might focus on increasing perceived control over constraints of using nutrition labels, acquiring skills for checking nutrition labels, as well as the benefits of using nutrition labels and receiving support from significant others for nutrition label use.

The purpose of this study was to provide preliminary data for better safety control over children's preference foods sold in school stores. The survey was conducted from June to July 2009, to collect 749 types of children's preference foods sold in 150 middle and high school stores nation-wide excluding Jeju Island and general and nutrition information were analyzed. Out of 749 types of snack food items, 689 and 602 snacks were sold at high school and middle school stores respectively. Among children's preference foods, cookies, bread, and ice-cream were the main items. Among them, 98% of snacks were domestic products and the price range of each individual snacks were mostly between 600 and 900 won. 27.8% of children's preference foods sold were found to be in the high calorie/low nutrition food group. Even though the proportion of candy and fruit/vegetable beverages sold were not high, their proportion in high calorie/low nutrition snack group were higher than 68.1%. Among the children's preference foods sold in middle and high school stores, carbonated drinks and ramen were continuously sold in certain middle and high schools, even though sales were prohibited. This study concludes that government, corporations and retailers should work together in developing healthier children's snack distribution environment. In addition, dairy products, which take up 15% of children's preference food, should be diversified to meet their nutrient requirements.

This study was conducted to investigate the effectiveness of a nutrition and exercise education program on weight control of adult women. The subjects of this study were 28 adult women aged 20-59 years residing in the Daegu area. The nutrition-exercise educational period was 12 weeks. The collected data consisted of items on general characteristics, anthropometric data, blood biochemical values, physical strength data, dietary behavior and nutrition knowledge scores of the subjects. During the 12 weeks of weight control, body mass index(BMI), % of body fat, body fat mass and waist-hip ratio significantly decreased. The level of plasma triglyceride decreased, but not significantly. The level of total cholesterol did not change compared to baseline before the program. After the weight control program, back muscle strength, sit-ups, push-ups, and sit-and-reach tests of the subjects significantly improved. The nutrition knowledge scores of the subjects significantly increased. Therefore, these results suggest that the nutrition-exercise education program may contribute effectively to weight reduction with improvement of physical strength in adult women.
