Science and philosophy of Korea traditional foods (K-food)
권대영,김순희,Chung Kyung Rhan,Daily Jim,Park Sunmin 한국식품연구원 2023 Journal of Ethnic Foods Vol.10 No.26
The foods, diets, lifestyles, and cultures that can be encountered throughout the world are different depending on the environment of each region and each ethnic group. Ethnic food has been developed according to the constraints of the given environment in terms of philosophical, agricultural, and geohistorical conditions. In other words, ethnic food is a product of efforts to cope with and overcome food safety, desirability, and the need for food storage for periods of famine. It would be a tradition and emergence created by accumulated wisdom that actively utilizes the given geographical and natural environment. Since the Ice Age, the development of all ethnic foods on the Earth has been unique in terms of their characteristics, due to the natural agro-ecological background of the region, through the movement and settlement of primitive mankind and wars of the Bronze Age. Therefore, it is impossible to understand the development of a particular ethnic food without understanding its historical background and geographical and agro-ecological characteristics. The same applies to Korean foods, which should be studied from this perspective. Nevertheless, until now, the history of food on the Korean Peninsula has been mainly studied by history scholars who can read Chinese characters rather than by natural scientists, resulting in errors and distortions in our understanding of the identity, history, and originality of Korean food. In this paper, we aim to correct these errors and distortions and to present scientifically validated research and the developmental background of Korean food in terms of its anthropological, historical, geographical, and cultural values, which is essential for K-food (Korean Traditional foods) to be known as a distinctly different world food rather than as a regional variant of Northeast Asian foods. Furthermore, we also aim to provide scientific truths by researching the health functionalities and cultural values of Korean food so that it can develop as a global food worldwide.

근위축측삭경화증 환자의 심폐소생술 시 적절한 흉부압박 깊이 연구: 후향적 연구
권대영,오재훈,이희경,강형구,임태호,고벽성,조용일,김홍중 대한응급의학회 2020 大韓應急醫學會誌 Vol.31 No.1
Objective: The chest compression depth recommended in the current guidelines for average adult cardiopulmonary resuscitation is approximately 1/4-1/5 depth of the external chest anteroposterior (AP) diameter and at least 50 mm but less than 60 mm. The purpose of this study was to determine the proper compression depth in patients with amyotrophic lateral sclerosis (ALS). Methods: A retrospective analysis of the chest computed tomography scans obtained between January 2014 and December 2018 was performed, and the chest anatomical parameters, such as external, internal chest, and heart AP diameters, were measured. The primary outcomes were a 1/4 and 1/5 depth of an external chest AP diameter. Based on the values of these parameters, the heart compression fractures (HCF) and over compression depth (OCD) from 40 to 60 mm depths with every 5 mm interval were calculated. All outcomes in the two groups were compared. Results: Ninety three of 108 ALS and 93 of 17,150 healthy individuals were selected randomly from a database and analyzed. The mean±standard deviations of 1/4 and 1/5 depth of the external chest AP diameter in ALS were significantly lower than in healthy individuals (48.57±4.60 mm vs. 53.43±4.93 mm, 38.86±3.68 mm vs. 42.75±3.94 mm, respectively, all P<0.001). The HCF values were similar in the two groups. The number of OCD with 55 and 60 mm in the ALS group were increased (all P<0.05, univariate analysis) Conclusion: An approximately 50 mm depth of chest compression could be appropriate, but an excessive depth greater than 55 mm is more likely to cause complications for ALS patients.

신증후성 출혈열 환자 42명을 대상으로 각 병기에 빠른 신장 및 신장 외 변화에 대한 초음파 소견을 분석하여 다음과 같은 결과를 얻었다. 신피질의 에코 변화는 발열기, 저혈압기, 핍뇨기에서는 고에코를 보인 예가 많았고 (각각 80%, 100%, 67%), 이뇨기에서는 동등 에코를 보인 예가 가장 많았으며(50%), 회복기에는 전 예에서 정상적인 저에코를 보였다. 신수질-피질의 구별상이 비정상적으로 뚜렷한 경우(Well defined)는 발열기부터 나타나기 시작하여(40%) 저혈압기에서 가장 많이 보이다가(80%) 핍뇨기부터 줄어들기 시작하여(53%) 회복기 때 완전히 소실되었다. 신중심 에코 복합체가 납작해지거나 소실되는 소견은 발열기, 저혈압기, 핍뇨기에서 각 각 73%, 80%, 73%로 높게 나타나다가 이뇨기에서는 31%로 떨어지고 회복기에서는 전 예에서 정상소견을 나타내었다. 신장의 길이는 이뇨기에서 회복기로 진행될 때에만 통계학적으로 유의한 감소를 보인 반면 신장의 두께와 MPI는 저혈압기에시 핍뇨기로 진행될 때 의미 있는 증가를 보이다가 핍뇨기와 이뇨기 및 이뇨기와 회복기 사이에서 현저한 감소를 나타내었다. TLR은 발열기로부터 핍뇨기 사이에서는 의미 있는 변화가 없었고 핍뇨기와 이뇨기 및 이뇨기와 회복기 사이에서 현저한 감소를 나타내었다. 신장 외 소견으로는 신 주위 삼출액, 복수, 늑막 삼출액 등이 관찰되었으며 이들 소견은 발열기부터 보이기 시작하여 핍뇨기에 가장 많은 빈도를 보이다가 이뇨기에 감소하기 시작하여 회복기에는 모두 소실되었다. 초음파로 확인 가능하였던 합병증은 신우 및 신배 확장이 5예(12%)였고 신 주위 혈종이 3예 (7% )였다. 결론적으로 신증후성 출혈열 환자에 있어서 신장 및 복부 초음파 검사는 병기에 따른 신장의 변화를 잘 관찰할 수 있을 뿐 아니라 주변 장기의 이상 유무 및 합병증까지 발견할 수 있으므로 환자의 진단 및 치료에 많은 도움이 될 수 있을 것으로 생각된다. We analysed sonographic changes in each phase of Hemorrhagic fever with renal syndrome in 42 patients with the following results. Renal cortical echo was hyperechoic during febrile(80%), hypotensive(100%) and oliguric(67%) phases, isoechoic in diuretic phase(57%) and hypoecholc in convalescent phase(100%). Abnormally well differentiated cortico-medullary junction was visible from febrile phase(40%), peaked in hypotensive phase(80%), decreasing from oliguric phase(53%), and disappeared in convalescent phase. Abnormal renal central echo complex was high in febrile, hypotensive, and oliguric phase(73%, 80%, 73%), decreased in diuretic phase(31%) and disappeared in convalescent phase. Renal length showed statistically significant decrease from diuretic to convalescent phase only, but thickness and MPI showed significant increase from hypotensive to oliguric phase and decrease not only from diuretic to convalescent phase but also from oliguric to diuretic phase. TLR showed no significant change from febrile to oliguric phase, but significant decrease from oliguric to diuretic and from diuretic to convalescent phase. Extra-renal pathologic findings were perinephric fluid collection, ascites, and pleural effusion which began to visualize at febrile phase, maximal at oliguric phase, decreased in diuretic phase and disappeared in convalscent phase. Sonographically detectable complications were dilatation of pelvocalyceal system in 5 cases(12 %), and perinephric hematoma in 3 cases(7%). In conclusion renal and abdominal ultrasonography is thought to be a very useful diagnostic modality in the diagnosis and treatment in patients with hemorrhagic fever because it can show us renal changes in different phases, extra-renal pathologies and complications.
