Prolonged Russia-Ukraine war, and unstable situation of supply and demand of global crops including the COVID-19 pandemic have raised awareness regarding food crisis, and in addition to this situation, export restriction measures imposed by some countries have accelerated the rise in the prices. Since the Republic of Korea depends annual crop consumption (21.32 million tons) mostly on the imports (food self-sufficiency rate in 2020 was 45.8%, crop self-sufficiency rate was 20.2%), our main task is to stably secure food. Now we need to put focus on building capacity to secure stable food supply, and actively manage and respond to risks. To overcome this condition, the Korean government set robust food sovereignty as its policy task, and has been focusing on the policy capacity by providing financial and policy support in parallel. We need to implement mid- to long-term measures to strengthen food security as well as to ensure domestic price stability. While increasing the domestic capacity to supply food in the mid- to long-term perspective, we are implementing projects to bring in crops which are inevitable to be imported by private companies. Specifically, we are making efforts to expand infrastructure for the public reserve and domestic production of wheat and beans which have low self-sufficiency rate, and to secure food sovereignty by providing support to secure global crop supply chain to private companies. The Ministry of Agriculture, Food and Rural Affairs plans to set a target for food self-sufficiency rate and prepare a policy to strengthen mid- to long-term food security by establishing a task force to strengthen mid- to long-term food security in the Ministry. Especially, although wheat is the second staple food, domestic wheat production and the foundation for the industry is poor. Compared to the wheat imports, domestic production of wheat is 30 thousand tons (self-sufficiency rate of 1%), leading to a vulnerable status against internal and external shocks. Through the establishment of the Wheat Industry Promotion Act (Feb. 2020) and the First Master Plan for Wheat Industry Promotion (Nov. 2020), the Korean government has developed a policy basis, and has been providing financial support in overall across the production, distribution and consumption process. In addition, the government established a production complex for Korean wheat and beans in order to supply affordable government-supplied commodities, provide education and consulting services, and create a high-quality stable production system, including facilities and equipment. We are also continuing to increase the public reserve for wheat and beans with the purpose of stable supply and demand as well as food security. The Korean government will establish and implement mid- to long-term measures to strengthen the foundation for domestic production across production, distribution and consumption process, and to stably secure global supply chain including through diversified import channels.

The objective of this study was to evaluate the effect of a healthy school tuck shop program, developed as a way of creating a healthy and nutritional school environment, on students' access to healthy foods. Five middle schools and four high schools (775 students) participated in the healthy school tuck shop program, and nine schools (1,282 students) were selected as the control group. The intervention program included restriction of unhealthy foods sold in tuck shops, provision of various fruits, and indirect nutritional education with promotion of healthy food products. The program evaluation involved the examination of students' purchase and intake patterns of healthy foods, satisfaction with the available foodstuffs, and utilization of and satisfaction with nutritional educational resources. Our results indicated that among of the students who utilized the tuck shop, about 40% purchased fruit products, showing that availability of healthy foods in the tuck shop increased the accessibility of healthy foods for students. Overall food purchase and intake patterns did not significantly change during the intervention period. However, students from the intervention schools reported higher satisfaction with the healthy food products sold in the tuck shop than did those from the control schools (all $P$ < 0.001), and they were highly satisfied with the educational resources provided to them. In conclusion, the healthy school tuck shop program had a positive effect on the accessibility of healthy food. The findings suggest that a healthy school tuck shop may be an effective environmental strategy for promoting students' access to healthy foods.

Distribution of Salmonella enterica serovars and their associated virulence determinants is wide-spread among food animals, which are continuously implicated in periodic salmonellosis outbreaks globally. The aim of this study was to determine and evaluate the diversity of five Salmonella serovar virulence genes (invA, pefA, cdtB, spvC and iroN) isolated from food animals and humans. Using standard microbiological techniques, Salmonella spp. were isolated from the feces of humans and three major food animals. Virulence determinants of the isolates were assayed using PCR. Clonal relatedness of the dominant serovar was determined via pulsed-field gel electrophoresis (PFGE) using the restriction enzyme, Xbal. Seventy one Salmonella spp. were isolated and serotyped into 44 serovars. Non-typhoidal Salmonella (NTS; 68) accounted for majority (95.8%) of the Salmonella serovars. Isolates from chicken (34) accounted for 47.9% of all isolates, out of which S. Budapest (14) was predominant (34.8%). However, the dominant S. Budapest serovars showed no genetic relatedness. The invA gene located on SPI-1 was detected in all isolates. Furthermore, 94% of the isolates from sheep harbored the spvC genes. The iroN gene was present in 50%, 100%, 88%, and 91% of isolates from human, chicken, sheep, and cattle, respectively. The pefA gene was detected in 18 isolates from chicken and a single isolate from sheep. Notably, having diverse Salmonella serovars containing plasmid encoded virulence genes circulating the food chain is of public health significance; hence, surveillance is required.

This study was conducted to investigate the effects of weight control programs on BMI, serum profiles, nutrition knowledge and eating behaviors of adult obese women. The subjects of this study were 33 adult obese women aged 30-65 years residing in Seoul. The weight control program for obese women included nutritional education, cognitive behavioral therapy and exercise for 12 weeks. The weight control experience of the subjects was 60.6%. They preferred physical exercise and diet restriction to weight control and 72.7% of subjects answered that the reasons for wanting to control their weight was health. The BMI of test subjects significantly decreased (p<0.001) from 28.3 to 27.1 after the 12 weeks of the weight control program. In addition, the % body fat significantly decreased (p<0.001) from 36.4% to 34.5% after completion of the weight control program. SGPT levels in the serum were also significantly decreased (p<0.05) after the program. Triglyceride levels significantly decreased from 194.9 mg/dL to 98.1 mg/dL (p<0.01) and the HDL cholesterol level significantly increased (p<0.01) from 55.8 mg/dL to 60.0 mg/dL after completion of the weight control program. Nutritional knowledge and eating behavior scores were significantly increased (p<0.001). In addition, the eating self-efficacy of the subjects was significantly increased (p<0.01); however, the food diversity scores were not changed after the program. These results suggest that the weight control program for adult obese women may be effectively used to promote weight reduction and improve nutritional knowledge and eating behavior.

요인분석을 이용하여 초등학생(4~6학년)과 중학생(2~3학년)이 인지하는 어머니의 양육방식과 식사지도방식에 관한 내재요인을 추출하고, 이들 요인들의 상호관련성 및 대상자들의 식행동과의 관련성을 살펴보았다. 어머니 양육방식은 총 10개의 요인(합리적 지도, 애정과 참여, 성취격려 및 기대, 일관성 있는 규제, 비난과 성냄, 과보호, 감정적 처벌, 육체적 처벌, 자녀가 좋아하는 것을 못하게 함으로써 처벌 및 처벌을 못함)으로 추출되었고, 2차 요인분석을 통하여 이들 10 요인은 3 양육방식(권위주의적인, 허용적인 및 권위있는)으로 축약되었다. 어머니의 식사지도방식은 총 8개의 요인(식사량 조절, 식품제한, 섭취강요, 모니터링, 바람직하지 않은 식행동 보여주기, 바람직한 식행동 보여주기, 편식 교정 교육, 바람직한 식행동 권장)으로 추출되었다. 초등학생과 중학생의 식행동 비교 결과, 중학생들은 초등학생에 비해 '부모와 함께 식사'하는 빈도가 낮으며 '건강에 유익한 식품 섭취빈도'는 낮고 '건강에 해로운 식품 섭취빈도'는 높았다. '권위주의적인' 방식을 택할수록 '섭취강요' 및 '바람직 하지 않은 식행동 보여주기' 경향이 높았고 이러한 관련성은 초등학생에서 더 높았다. '허용적인' 방식을 택할수록 '올바른 식습관 권장' 점수가 낮게 나타났다. '권위 있는' 방식은 초등학생과 중학생 모두 '바람직하지 않은 식행동 보여주기'를 제외한 모든 식사지도방식 요인과 유의한 양의 상관관계를 나타내었고(p<0.0001), '편식개선 노력'과 '바람직한 식행동 권장' 점수가 가장 높았다. '권위주의적인' 방식일수록 초등학생의 '건강에 해로운 식품 섭취빈도'가 높았고(p<0.001), '허용적인' 방식일수록 중학생의 '혼자식사' 및 '건강에 해로운 식품 섭취빈도'가 높았다. '권위 있는' 방식을 택할수록 초등학생과 중학생 모두 '건강에 유익한 식품 섭취빈도'가 높았다(p<0.001). 또 '권위 있는' 방식은 초등학생이 '부모와 함께 식사'하는 횟수는 높고 '혼자 식사'하는 횟수는 낮았으며 중학생에서는 관련성이 없었다. 이상에서 볼 때, 어머니의 양육방식과 차원, 식사지도방식의 차원들은 상호관련성이 높으며, 어머니의 '권위 있는' 양육방식은 초등학생 및 중학생에서 가장 바람직한 것으로 드러났다. 한편, 초등학생과 중학생에서 가장 바람직하지 못한 양육방식은 각각 '권위주의적인' 방식과 '허용적인' 방식으로 나타났고, 어머니의 양육방식은 자녀의 연령에 따라 다르게 영향을 미치는 것으로 드러났다.

This study was conducted with 20 female gymnasts and 23 age-matched controls to examine pattern, weight control behavior and nutritional status. Most gymnasts(95.0%) reported that they used weight-control methods, while relatively few age-matched controls employed these methods. These methods included sauna(95.0%), food restriction(90.0%), excess exercise (70.0%), laxative abuse(10%) and use of diet pills(10%). Gymnasts had significantly (p<0.05) lower scores for statements related to 'sneaking food', 'vomiting after overeating', showing more negative eating behavior than age-matched controls. Energy intake of gymnasts was 968.9$\pm$421.4kcal while energy expenditure was 2,091$\pm$361kcal, showing negative evergy balance(-1,1225$\pm$534.6kcal). Female gymnasts consumed less than 70% of the RDA for protein, calcium, iron, vitamin A, thiamin, riboflavin and niacin, which reflects their low energy intake. The average intakes of calcium, iron, vitamin A, thiamin, riboflavin and niacin did not meet the recommended dietary allowances for their age groups. Adolescent athletes who train vigorously and consume a low-energy diet may be exposed to an increase in potential health risks. Therefore, individuals who advise athletic adolescents regarding training and dietary habits need to emphasize the importance of consuming an appropriate energy intake to support performance as well as growth and development. The sports nutritionist is in a position to convey such information to coaches, physicians, parents and to the athletes themselves.

The effect of k-casein (k-CN) variant on milk production traits (milk yield, fat yield, protein yield, fat percentage and protein percentage) was estimated for 568 Holstein cows in the first lactation. The k-CN valiant were determined by PCR-RFLP (restriction fragment length polymorphism) technique at the DNA level. Single trait linear model was used for the statistical analysis of the data. Result of this study indicated that k-CN variant affected significantly milk yield (P<0.05) and protein yield (P<0.01). Animals with the BB variant produced 622kg milk more and had protein yield higher by 32kg compared with animals with the AA variant No associations between the k-CN variants and other milk production trait were found. Therefore, milk and protein yield may be improved through milk protein typing by increasing the frequencies of k-CN B variant in dairy cattle population. In cheese making, it will be also preferable to have milk with the B variant of k-CN, which gives higher yield having a better quality than the A variant milk.
