  • 레토르트 삼계탕은 장기간 저장되는 제품이므로 포장 불량률을 가능한 한 최소화하는 것이 품질 안전과 소비자 식중독 문제를 방지하기 위해서 중요한 사안이다. 따라서 업계에서는 현행 사용되는 삼계탕용 포장재를 이용하여 저장 시험을 병행하되 기존 포장재의 물성을 표준화하고, 아울러 포장작업시 가능한 한 포장내 잔존산소량이 낮게 유지되는 포장방법을 동원하고, 봉함부위가 오염되지 않도록 유의하며 멸균 후 열봉함강도가 낮아지는 것을 감안하여 포장재 스펙을 결정하는 방안이 강구되어져야 할 것이다. 이를 위해서는 가능한 한 포장내 잔존산소량을 줄이기 위하여 포장내 headspace를 줄이거나 질소 등 비활성기체를 주입 후 포장하는 것이 바람직하겠다. 그러나 현행 업계에서 삼계탕을 질소치환포장하는 것이 공정의 속도와 운용비용 등을 고려할 때 쉽지 않을 것으로 판단된다. 따라서 삼계탕 포장시 육수의 충진온도는 최소한 85이상 가열된 상태로 주입하고, 주입시 열봉함부위가 오염되지 않도록 유의하며, 필요하면 guide bar등과 같은 보조 장치를 설치하거나 파우치 밀봉 전 headspace를 압착하는 기술, 그리고 파우치 하부의 유사핀홀 현상을 방지하기 위한 보호대를 설치하여 육수를 충진하는 기술 등을 적용하는 것이 바람직할 것으로 사료된다. 그리고 멸균 처리 후 봉함강도가 감소하는 만큼 이를 감안하여 포장재의 선택과 포장작업이 이루어져야 할 것으로 판단된다.

  • BACKGROUND/OBJECTIVES: Despite successes recorded in combating iodine deficiency, more than 2 billion people are still at risk of iodine deficiency disorders. Rural landlocked and mountainous areas of developing countries are the hardest hit, hence the need to explore and advance novel strategies such as biofortification. SUBJECTS/METHODS: We evaluated adoption, purchase, and consumption of iodine biofortified vegetable legumes (IBVL) using the theory of protection motivations (PMT) integrated with an economic valuation technique. A total of 1,200 participants from three land-locked locations in East Africa were recruited via multi-stage cluster sampling, and data were collected using two, slightly distinct, questionnaires incorporating PMT constructs. The survey also elicited preferences for iodine biofortified foods when offered at a premium or discount. Determinants of protection motivations and preferences for iodine biofortified foods were assessed using path analysis modelling and two-limit Tobit regression, respectively. RESULTS: Knowledge of iodine, iodine-health link, salt iodization, and biofortification was very low, albeit lower at the household level. Iodine and biofortification were not recognized as nutrient and novel approaches, respectively. On the other hand, severity, fear, occupation, knowledge, iodine status, household composition, and self-efficacy predicted the intention to consume biofortified foods at the household level; only vulnerability, self-efficacy, and location were the most crucial elements at the school level. In addition, results demonstrated a positive willingness-to-pay a premium or acceptance of a lesser discount for biofortification. Furthermore, preference towards iodine biofortified foods was a function of protection motivations, severity, vulnerability, fear, response efficacy, response cost, knowledge, iodine status, gender, age. and household head. CONCLUSIONS: Results lend support for prevention of iodine deficiency in unprotected populations through biofortification; however 'threat' appraisal and socio-economic predictors are decisive in designing nutrition interventions and stimulating uptake of biofortification. In principle, the contribution is threefold: 1) Successful application of the integrated model to guide policy formulation; 2) Offer guidance to stakeholders to identify and tap niche markets; 3) stimulation of rural economic growth around school feeding programmes.

  • Objective: Dairy cattle nutrient requirement systems acknowledge amino acid (AAs) requirements in aggregate as metabolizable protein (MP) and assume fixed efficiencies of MP used for milk protein. Regulation of mammary protein synthesis may be associated with AA input and milk protein output. The aim of this study was to evaluate the effect of nanoemulsified methionine and cysteine on the in-vitro expression of milk protein (casein) in bovine mammary epithelial cells (MAC-T cells). Methods: Methionine and cysteine were nonionized using Lipoid S 75 by high-speed homogenizer. The nanoemulsified AA particle size and polydispersity index were determined by dynamic light scattering correlation spectroscopy using a high-performance particle sizer instrument. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay was performed to determine the cytotoxicity effect of AAs with and without nanoionization at various concentrations (100 to $500{\mu}g/mL$) in mammary epithelial cells. MAC-T cells were subjected to 100% of free AA and nanoemulsified AA concentration in Dulbecco's modified Eagle medium/nutrient mixture F-12 (DMEM/F12) for the analysis of milk protein (casein) expression by the quantitative reverse transcription polymerase chain reaction method. Results: The AA-treated cells showed that cell viability tended to decrease (80%) in proportion to the concentration before nanogenesis, but cell viability increased as much as 90% after nanogenesis. The analysis of the expression of genetic markers related to milk protein indicated that; ${\alpha}_{s2}$-casein increased 2-fold, ${\kappa}$-casein increased 5-fold, and the amount of unchanged ${\beta}$-casein expression was nearly doubled in the nanoemulsified methionine-treated group when compared with the free-nanoemulsified methionine-supplemented group. On the contrary, the non-emulsified cysteine-administered group showed higher expression of genetic markers related to milk protein ${\alpha}_{s2}$-casein, ${\kappa}$-casein, and ${\beta}$-casein, but all the genetic markers related to milk protein decreased significantly after nanoemulsification. Conclusion: Detailed knowledge of factors, such nanogenesis of methionine, associated with increasing cysteine and decreasing production of genetic markers related to milk protein (casein) will help guide future recommendations to producers for maximizing milk yield with a high level of milk protein casein.

  • This study was designed to evaluate the changes and improvements in the Korean diet during the last thirty years (since independence in 1945), and to make recommendations for the improvement of their nutritional status, consequently contributing to the physical and mental welfare of the Korean people. The results and recommendations are as follows: 1. The total calorie and carbohydrate intake decreased by $8{\sim}12%$ in the 1970's, as compared with the 1940's and the 1950's. 2. The intake of calcium and vitamiu A increased $30{\sim}50%$ and $20{\sim}60%$ respectively in the 1960's and 1970's as compared with the 1940,s. But this intake level is still lower than the RDA values. 3. The vitamin C intake was somewhat higher in the mountainous and farming areas than in urban areas. 4. In the 1970's, the decrease of untriend intake due to seasonal variation was marked especially for protein, niacin, vitamin $B_1$, and vitamin C. 5. The consumption of protein foods (meats and legumes) increased in an amount of $15{\sim}36g$ per day. There was a marked increase in the intake of meat in farming areas and of milk in urban areas in the 1970's. This increased intake of animal proteins is a very desirable dietary change. 6. The cereal consumption was lowest in urban areal, but there was a general decrease in the intake of the cereal group in the entire area in the 1970's. For the farmers, the intake of cereal food decreased most, from 750 g to 576 g, but cereals still composed a high proportion of the entire diet. 7. Fruits and vegetables showed the highest intake for the urban people, as expected. For the whole area, this food group showed an increase of 8.7% in the 1970's, as compared with the 1960's. 8. The gradual ihcrease in the intake of the fats and oil group was a desirable dietary change. but the absolute amount was too low. 9. A 7% increase in height and a 9% incrrase in weight for growing children and adolescents was observed in the 1970's as compared with the 1940's, but several kinds of deficiency diseases, such as nutritional anemia and dental caries were still apparent in many areas. 10. To improve cur food life and to cope with food shortages faced in Korea, an efficient and nationwide nutrition education program should be implemented. This would maximize efficiency of intake from the limited food sources for a balanced diet. 11. As it is of utmost importance to provide growing children with a desirable physical, sccial mental, and especially nutritional environment, a well-planned and organized school feeding program should be practiced widely and efficiently. 12. Young mothers and pregnant women should be educated on the importance of their children's nutrition, especially for the critical fetal and infancy periods. 13. More thorough and continuous nutritional survey studies on the changes in dietary patterns for the entire nation should be pursued, evaluated and documented. This would Provide a good information guide for future nutritional study programs. 14. It is the nutritionistist's strong desire that national leaders, especially decision makers recognize the fact that improvement of the nutritional status of the People is one of the most economic and preventative ways of improving their physical and mental health. This is closely related to the economic development and strength of the nation.

  • UN adopted the 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs) in 2015, a set of 17 objectives with 169 targets expected to guide actions over the next 15 years (2016-2030). One goal expressly focuses on the oceans, that is, SDG 14 'Conserve and sustainably use the oceans, seas and marine resources for sustainable development'. More than 30% of fish stocks worldwide were classified by FAO(2016) as overfished. Globally, world capture fisheries are near the ocean's productive capacity with catches on the order of 80 million metric tons. Aquaculture production is increasing rapidly and is expected to continue to increase, but aquaculture encounters some environmental challenges, including potential pollution, competition with wild fishery resources, potential contamination of gene pools, disease problems, and loss of habitat. Accordingly, there have been a variety of world organization and conferences stressing the importance of the implementation of the ecosystem-based fisheries management(EBFM) to overcome these problems. Annual catch of Korean fisheries have shown continuously declining patterns since late 1990s. Most fish stocks are currently known to be over-exploited, and some stocks are depleted due to the increase in fishing intensity and over-capitalization of fishing fleets. Other reasons for the depletion are land reclamations and coastal pollution, which destroy spawning and nursery grounds along the coastal regions. Aquaculture production is also increasing rapidly in Korea. However, several important issues such as gene pool and interaction with capture fisheries should be considered. The EBFM approach should use the best available information coupled with a reasonable application of the precautionary approach. The EBFM has global relevance, and so the real challenge will be to develop and use reliable, robust and cost-effective means of assessing and monitoring the status of ecosystems and their resources, and rapid means of detecting any undesirable and excessive impacts that threaten sustainable use. Future fisheries education should take into account UN's SDGs, which were adopted to achieve the global 2030 agenda. However, there are some difficulties in the current fisheries education system in Korea. First, the current education organizations are limited within the old frame of traditional fisheries sciences. Second, the fisheries education is currently lack of the future-oriented education system and of customized schools or departments. Third, the on-going fisheries education has been based upon few educational policies which are sufficiently relevant to holistic SDGs of the global standard. Accordingly, directions to modern fisheries education for achieving SDGs would be, first, the transition of fisheries education structure into the future-oriented and customized education system. Second, fisheries education needs to shift to the new paradigm, which combines traditional fisheries science education with related fields such as oceanography and environmental sciences to adopt the concept of EBFM. Lastly, fisheries education should accompany relevant policies for effectively achieving SDGs.

  • Cowpea might have been introduced from China to Korea and cultivated for several hundred years but it has never been a staple food crop in Korea. In this study, genetic diversity of 492 Korean cowpea landrace accessions that have passport information was estimated using six SSR markers. The mean of Weir's gene diversity was 0.665 from all accessions investigated in the study. Cowpea gene diversity of six local provinces in Korea was ranged from 0.370 in accessions of Gangwon to 0.680 in Jeonra provinces. Low gene diversity of the cowpea genepool of Gangwon province was probably derived from relatively few introductions. Especially SSR markers VM36 and VM39 seem to be good markers to distinguish the Gangwon accessions from others by occurring at a specific locus with higher than 78% of allele frequency. Except for the Gangwon province with the low genetic diversity, gene diversity of cowpea accessions from other provinces was ranged from 0.600 to 0.680 indicating no big differences among provinces. Distribution pattern of the allele frequencies was similar among the other provinces. This may reveal that Korean farmers might exchange cowpea seeds easily with even their neighbors with geographical barriers. A core collection, 100 landraces, ca. 20% of base collection, was developed at the 70% of a similarity coefficient level using random sampling approaches after stratification of the entire landrace collection based on the phenetic dendrogram. The variability of SSR in the base and core collections of Korean cowpea landrace was compared by calculating Weir's gene diversity. The mean of Weir's gene diversity of the core was 0.707 while that of the base collection was 0.665. The higher diversity index in the core collection indicates that it maintains the initial variability and well represents the base collection. The core collection included one of determinate accession (IT 216155) and two of no branching type accessions (IT 103959 and IT 161024). The core collection could be used to guide more efficient management and utilization of the entire collection. This core collection should be revised periodically as additional accessions are collected and further characterization is conducted.

  • 의약품 부족은 전 세계적으로 보건학적 위험을 초래할 수 있는 문제이다. 본 연구의 목적은 미국, 캐나다, 일부 유럽 국가에서 국가의 의약품 부족에 대응하는 정책을 비교하고, 시사점을 도출하고자 하였다. 본 연구는 'drug shortage'와 'stock-out'와 같은 키워드를 사용하여 검색엔진과 구글학술검색을 통해 검색된 보고서 및 논문들을 검토하였다. 미국은 의약품 제조 중단에 대한 보고시스템을 구축하고, 의약품 공급망 관리의 중요성을 강조하고 있다. 또한 의약품 부족에 대한 대응체계를 마련하고자, 정부부처와 민간기관 간 의약품 부족 테스크포스를 설립했다. 캐나다는 중앙 및 지방 정부, 민간 부문의 대표를 참여시켜 의약품 부족에 관한 이해관계자 운영위원회를 설립하고, 의약품 부족 문제에 대해 단계적 접근방식을 채택하고 있다. 유럽의약품청(European Medicines Agency)은 2019년 유럽 경제 지역(European Economic Area)의 의약품 부족 커뮤니케이션에 대한 지침을 발표하였다. 외국에서는 의약품 부족을 모니터링하고 적시에 대응하기 위해 다양한 이해관계자 간의 의사소통에 중점을 두고 있다는 점을 확인하였다. 국내에서도 의약품 수급불안정 문제가 지속되는 만큼, 전담조직을 구성하고 가이드라인을 마련하며, 정부, 제약사, 의약품 유통사 등 민간부문의 협의와 조정을 통해 문제를 개선하는 것이 필요하다.
