최근 드론 산업은 미래를 이끌어갈 신산업으로 부상하고 있다. 이러한 기대에도 불구하고 드론으로 인해 생기는 여러 문제들 중에서 개인정보침해 관련 문제는 기술적으로 쉽게 풀리지 않아서 드론 사용에 대한 법적인 규제만 더 강화하고 있는 실정이다. 본 논문은 드론 촬영물이 묵시적으로 가지고 있는 개인정보 침해문제를 클라우드 환경 가운데 기술적으로 풀어내었다. 사용자는 자신의 개인정보 침해 요소가 제거된 안전한 영상을 이용할 수 있도록 실시간 촬영 시 특정 사람 객체에 대한 마스킹을 진행할 수 있다. 라즈베리파이 카메라와 드론을 이용해 동영상을 촬영한 뒤 소켓 통신을 통해 이를 클라우드 환경에서의 서버로 전송하면 서버는 실시간으로 마스킹 처리를 진행하며 마스킹이 완료된 영상은 최종적으로 서버에 저장된다. 사용자는 모든 사람 객체 마스킹과 특정인을 제외한 모든 사람 객체 마스킹이라는 두 가지 옵션 중에서 원하는 옵션을 선택하여 개인정보 마스킹 처리를 진행할 수 있다.

Purpose: High-sensitivity C-reactive protein (hs-CRP) is primarily synthesized in the liver upon stimulation of infectious disease cytokines, such as interleukin-6 (IL-6), and is used as a biological marker of systemic inflammation. Previous studies reported that hs-CRP is closely related to diet and abdominal obesity. Furthermore, a dietary score favoring the consumption of vegetables, fruits, and whole grains over meat and saturated fat reduced inflammation and decreased the prevalence of obesity and abdominal obesity. Nevertheless, no studies have examined whether hs-CRP mediates the relationship between dietary scores and abdominal obesity, and research on the Korean Healthy Eating Index (KHEI) is lacking. Therefore, the present study examined the association between the KHEI and abdominal obesity and the mediating effect of hs-CRP. Methods: In total, 17,770 adults aged ≥19 years were included in the study using the Korea National Health and Nutrition Examination Survey 2015–2018. KHEI was developed to assess the overall diet quality of Korean adults. Multivariable linear and logistic regression analyses assessed the relationship between KHEI, hs-CRP, and abdominal obesity. The mediation analysis with the bootstrapping method was performed using SAS MACRO. Results: Among women, the odds ratio (OR) of abdominal obesity prevalence was lower in the highest KHEI compared to the lowest KHEI after adjusting for age, body mass index, educational level, income level, occupational status, marital status, household type, region type, alcohol consumption, smoking status, physical activity, total energy intake, and hs-CRP (OR 0.744, 95% confidence interval 0.598–0.926). The association between KHEI and abdominal obesity was partially mediated via hs-CRP, and the mediated proportion was 68.7% in men and 38.1% in women. Conclusion: A substantial relationship was observed between the KHEI and abdominal obesity among females. Moreover, according to the KHEI, abdominal obesity may be mediated partially by hs-CRP.

This study explored the research trends on metabolites associated with metabolic syndrome in Koreans using data from the Korean Genome and Epidemiology Study (KoGES). A scoping review methodology was employed to analyze articles published between 2016 and 2024 that utilized the KoGES dataset. Relevant articles were identified through the RISS, KISS, DBpia, PubMed, and Google Scholar databases. A total of 9 articles were selected, focusing on the associations between various metabolites and metabolic syndrome components. Among the selected articles, amino acidrelated metabolites were addressed in 7 articles, lipid-related metabolites such as phosphatidylcholines in 7 articles, sphingomyelin metabolites in 3 articles, carbohydrate metabolites like hexose in 3 articles, and biogenic amines such as spermine in 2 articles. Amino acids, particularly branched-chain amino acids (BCAAs), were positively associated with type 2 diabetes risk, while glycine and arginine bioavailability showed protective effects. Lipid-related metabolites, such as lysophosphatidylcholines and sphingomyelins, were linked to both metabolic syndrome and its components, including hypertension and postprandial glucose. Hexose, a carbohydrate metabolite, was associated with increased insulin resistance and impaired pancreatic β-cell function, contributing to elevated postprandial glucose levels. Biogenic amines, particularly spermine, were negatively related to type 2 diabetes risk. This scoping review highlights the importance of metabolomics in the early diagnosis and personalized management of metabolic syndrome, demonstrating the value of large-scale data like KoGES in developing tailored health strategies for diverse populations.

본 연구에서는 김 주정 추출물이 고지방식이로 유도된 비만 마우스에서 대사성 질환에 미치는 영향과 작용 기전을 규명하고자 하였다. 그 결과 김 주정 추출물은 비만, 이상지질혈증, 지방간을 개선하였으며 그 작용 기전으로서 지질 대사, 세포사멸, 산화스트레스, 염증을 억제하였다. 따라서 김 주정 추출물은 식이로 인한 대사 장애를 보호할 수 있으며, 대사성 질환의 예방과 치료를 위한 잠재력을 갖춘 소재로 사료된다. Purpose: Metabolic diseases share common risk factors, requiring the development of therapeutic agents with multi-target effects. Although the ameliorating effects of Porphyra tenera ethanol extract (PTE) have been reported on some individual metabolic disorders, studies addressing various other metabolic diseases are still limited. This study investigated the ameliorating effects of PTE supplementation for 12 weeks on obesity, dyslipidemia, and hepatic lipid metabolism in high-fat diet (HFD)-induced obese mice and its molecular mechanisms.<BR/>Methods: Male C57BL/6 mice (n = 12/in each group) were divided into six groups for 12 weeks: control, HFD, chow diet + 1% porphyran, chow diet + 4% porphyran, HFD + 1% porphyran (HPYP-L), and HFD + 4% porphyran (HPYP-H). To confirm the attenuation of metabolic disease in vivo, mice in the HFD, HPYP-L and HPYP-H groups were fed 60% HFD to induce obesity. PTE was prepared using ethanol and dissolved in drinking water to concentrations of 1% and 4% porphyran. After 12 weeks of free PTE intake, body weight measurement, serum analysis, histopathological analysis, real-time quantitative polymerase chain reaction, and Western blot analysis of liver tissues were performed for comparative evaluation.<BR/>Results: After 12 weeks, the HPYP-L and HPYP-H groups showed a decreased body weight, improved blood lipids, and reduced hepatic lipid droplet accumulation vs. the HFD group. Liver acetyl-CoA carboxylase, was suppressed in the HPYP-L group vs. the HFD group. The B-cell lymphoma 2 (Bcl-2)-associated X protein/Bcl-2 protein and messenger RNA (mRNA) level ratio in the liver decreased after PTE intake, indicating inhibition of apoptosis. Interleukin-1 beta mRNA expression in the liver was reduced in the HPYP-L group vs. the HFD group. In the liver, lower protein carbonylation levels in the HPYP-H group indicated reduced oxidative stress, while the increased mitochondrial DNA/nuclear DNA ratio indicated improved mitochondrial function.<BR/>Conclusion: PTE protects against diet-induced metabolic disorders and could be a potential agent for the prevention and treatment of metabolic diseases
