본 연구는 2022년 2월 24일 러-우크라이나 전쟁 발발 이후의 러시아 문화정책의 변화와 특징을 고찰한다. 러시아의 문화정책은 우크라이나와 전쟁을 시작한 이후 강력한 민족주의적 성향을 보이며 우경화되고 있다. 우크라이나 전쟁 이후 한국과 러시아는 상호 비우호국가로 지정하여 얼 어붙은 양국 관계와 국제 정세 속에서도 여러 분야의 K-콘텐츠는 러시 아 사회에서 선전하고 있으며 경제적인 효과까지 창출하고 있다. 아직까 지 러시아 사회에서 한국의 대중문화는 러시아 청년들의 하위문화로 주 류문화에 영향을 줄 만큼 폭발적인 반응을 보이는 것은 아니지만 그 수 요는 기하급수적으로 증가하고 있다. 대한민국 정부는 양국의 대중문화 분야의 인적·물적 교류 활성화를 전제로 실리적이고 실효성 있는 방안을 고려해야 한다.

Hypertension is characterized by excessive renin-angiotensin system activity, leading to blood vessel constriction. Several synthetic compounds have been developed to inhibit renin and angiotensin-converting enzyme (ACE). These drugs often have adverse side effects, driving the exploration of plant protein-derived peptides as alternative or supplementary treatments. This study assessed the phenolic compound and amino acid content and the antioxidant and antihypertensive activity of 5 South Korean staple crops. Sorghum had the highest phenolic compound content and exhibited the highest antioxidant activity. Millet grains, particularly finger millet (38.86%), showed higher antihypertensive activity than red beans (14.42%) and sorghum (17.16%). Finger millet was found to contain a large proportion of branched-chain, aromatic, and sulfur-containing amino acids, which are associated with ACE inhibition. In particular, cysteine content was positively correlated with ACE inhibition in the crops tested (r=0.696, p<0.01). This study confirmed that the amino acid composition was more correlated with the antihypertensive activity of grains than the phenolic compound content. Finger millet mainly contained amino acids, which have higher ACE inhibitory activity, resulting in the strongest antihypertensive activity. These findings underscore the antihypertensive potential of select crops as plant-based food ingredients, offering insight into their biological functions.

식물의 흡수를 통한 공기오염물질 제거는 생육 상태에 따라 그 효과가 달라진다. 실내에서 토양수분의 공급은 식물의 생 육을 위한 기본적인 관리 사항이다. 따라서 본 연구는 토양수 분함량에 따른 생리적 반응이 가스상 공기오염물질인 톨루엔 저감에 미치는 영향을 구명하고, 최적의 생육과 공기 정화 효 과를 위한 적정 토양수분함량을 찾고자 수행하였다. 이를 위 해 스파티필름과 파키라를 사용하여 40일 동안의 평균 토양 수분함량을 25%, 20%, 15%, 10%로 처리한 후 양자수율, 광 합성률, 기공전도도, 증산량 등 생리적 지수와 엽면적당 톨루 엔 저감량을 측정하였다. 그 결과 스파티필름은 토양수분함량 을 20~25%로 관리할 때 생육이 양호하고 최적의 톨루엔 저 감 효과를 얻을 수 있을 것으로 판단되며, 10% 이하 건조에 대한 주의가 요구된다. 반면 파키라는 토양수분함량 20% 이 하 처리구에서 톨루엔 저감량이 증가하였으나 10% 처리구에 서 생장량이 저하될 가능성이 있으므로, 공기 정화와 생육을 위한 최적 토양수분함량은 15~20% 범위이며, 25% 이상으로 장기간 유지하는 것은 과습을 유발할 가능성이 있는 것으로 판단된다.

증강현실은 가상현실과는 구별되는 개념으로, 실제 세계와 가상 세계의 요소가 혼합된 상호작용 환경이다. 본 연 구는 가상현실 또는 일상에서 노출될 수 있는 일반적인 콘텐츠를 활용하여, 증강현실이 사용자 경험에 미치는 영향 을 검증하였다. 본 연구에서는 증강현실 사이버 멀미를 유발하기 위해서 조건에 따라 증강현실 노출 시간과 콘텐츠 의 움직임 속도를 조작하였다. 실험 과정에서 참가자는 증강현실 기기를 120분 동안 착용하고 30분씩 시뮬레이션 레이싱 게임을 시청하며 색 변화 탐지 과제를 수행하였고, 그로 인해 유발된 주관적인 불편감을 SSQ 설문지를 이용 해 보고하였다. 실험 결과, 증강현실 노출 시간이 길어질수록 사이버 멀미는 점진적으로 증가하였으며 기기를 해제 한 후에도 사이버 멀미는 지속되었다. 하지만, 움직임 속도는 사이버 멀미에 미미한 영향을 미쳤다. 특히, 메스꺼움 증상과 방향 감각 상실 증상이 높게 유발되는 가상현실과는 다르게 증강현실은 안구 운동 불편감에 대한 보고가 높게 관찰되었다. 본 연구는 증강현실 경험이 가상현실 경험과는 구별됨을 보여주며, 증강현실 경험으로 유발될 수 있는 인체 영향성을 다면적으로 측정했다는 점에서 의의가 있다.

The study confirmed the "house search report(家宅搜索調書)" containing criminal records during the Japanese colonial period, as well as the production process and the way of expressing the illustrations contained in them. It also explored architectural values through analysis of the location and use of the building. This records the discovery of evidence by searching the residences of those involved in the crime from 1919 to 1922. The illustrations contained in this record were not standardized, so the contents of the article differed depending on the author's background and cultural experience. Nevertheless, this painting reflects the regional characteristics of traditional houses located throughout the Korean Peninsula. It is also evidence that the house was used for cultural, commercial, and industrial purposes, beyond the general assumption that it was used only for residential purposes. The "House Search Report(家宅搜索調書)" provides information on ordinary buildings that existed as the background of everyday life, rather than buildings with a specific purpose or exceptional design. It is evaluated as an important resource for understanding the diverse life and spatial structures of buildings during that time.

This study aimed to investigate the acrylamide content in frozen food products after cooking. Twenty samples of bread (Group 1) and 30 samples of processed tuberous and corn vegetable products (Group 2) were selected. Acrylamide levels were quantified using liquid chromatography tandem-mass spectrometry (LC-MS/MS). The frozen food samples were heated using the air fryer cooking method according to the product packaging and were compared to ready-to-eat French fries (Group 3). The results showed that the acrylamide content was the highest in group 3, followed by that in group 2 and group 1. The acrylamide content of all the samples was found to be within the domestic recommended standard of 1 mg/kg. However, when the samples that exceeded EU benchmark level (0.5 mg/kg) were selected and cooked using the deep-fat frying method according to the product packaging, one of them showed the acrylamide content of 1.83 mg/kg, which exceeded the domestic recommended standard. The present study highlights the need for continued evaluation and management to reduce acrylamide contents in frozen foods, as increasing domestic exposure to acrylamide is concerning.

This study investigated the nutritional characteristics of before and after fermentation of domestic soybean (Glycine max L.) by Rhizopus oligosporus. The soybean storage proteins, β-conglycinin (11S globulin) and glycinin (7S globulin), were the most abundant in Seonyu (SY) and Danbaegkong (DBK), with concentrations of 253.4 mg/g and 193.0 mg/g, respectively. For 11S/7S related to sulfur-containing amino acid, DBK had a value of 0.95, making it the most excellent nutritionally among all the cultivars. The free amino acid content significantly increased from 0.04~10.45 mg/g before fermentation to 1.37~16.95 mg/g after fermentation, and the essential amino acid composition increased, confirming an improvement in protein quality after fermentation. Phytic acid, known as a nutritional inhibitor of soybeans, decreased from 1.66~2.13 g/100 g before fermentation to 0.90~1.58 g/100 g after fermentation, suggesting that mineral absorption inhibition was alleviated. In addition, the trypsin inhibitor content is suppressed by 76.20% to 81.25% after fermentation, which is expected to improve protein utilization in the body. This study confirmed some properties of fermented products by Rhizopus oligosporus using domestic soybeans, and these results are presented to serve as the basic data for establishing new uses of Korean soybean cultivars.

This study aimed to investigate the growth and phenol content changes of basil (Ocimum basilicum L.) under five different light intensities and photoperiods, maintaining the same Daily Light Integral (DLI) conditions in a plant factory. Basil seeds were sown on a rockwool medium for four weeks and then transplanted. To maintain a DLI 17mol·m-2·d-1, light intensity and photoperiod were set at 16h-295, 18h-260, 20h-235, 22h-215, and 24h-200μ mol·m-2·s-1 and cultivated for four weeks. The harvested results showed that basil plant height, number of lateral branches, and leaf number tended to decrease from the 16h-295 treatment to the 24h-200 treatment. Shoot fresh weight, dry weight, leaf area, leaf width, and leaf length were significantly higher in the 18 h-260 treatment. The total phenolic contents in the 18h-260 treatment was significantly higher by 51.3%, 172.7%, 111%, and 119.7% compared to the 16h-295, 20h-235, 22h-215, and 24h-200 treatments, respectively. Therefore, it is anticipated that cultivating basil under the condition of 18h-260 treatment could yield enhanced growth quality and an increase in total phenolic contents.

Ultra-violet (UV) light is one of abiotic stress factors and causes oxidative stress in plants, but a suitable level of UV radiation can be used to enhance the phytochemical content of plants. The accumulation of antioxidant phenolic compounds in UV-exposed plants may vary depending on the conditions of plant (species, cultivar, age, etc.) and UV (wavelength, energy, irradiation period, etc.). To date, however, little research has been conducted on how leaf thickness affects the pattern of phytochemical accumulation. In this study, we conducted an experiment to find out how the antioxidant phenolic content of kale (Brassica oleracea var. acephala) leaves with different thicknesses react to UV-A light. Kale seedlings were grown in a controlled growth chamber for four weeks under the following conditions: 20°C temperature, 60% relative humidity, 12-hour photoperiod, light source (fluorescent lamp), and photosynthetic photon flux density of 121±10 μmol m-2 s-1. The kale plants were then transferred to two chambers with different CO2 concentrations (382±3.2 and 1,027±11.7 μmol mol-1), and grown for 10 days. After then, each group of kale plants were subjected to UV-A LED (275+285 nm at peak wavelength) light of 25.4 W m-2 for 5 days. As a result, when kale plants with thickened leaves from treatment with high CO2 were exposed to UV-A, they had lower UV sensitivity than thinner leaves. The Fv/Fm (maximum quantum yield on photosystem II) in the leaves of kale exposed to UV-A in a low-concentration CO2 environment decreased abruptly and significantly immediately after UV treatment, but not in kale leaves exposed to UV-A in a high-concentration CO2 environment. The accumulation pattern of total phenolic content, antioxidant capacity and individual phenolic compounds varied according to leaf thickness. In conclusion, this experiment suggests that the UV intensity should vary based on the leaf thickness (age etc.) during UV treatment for phytochemical enhancement.

본 연구는 수분함량과 미생물 첨가제가 알팔파 사일리지의 발효특성과 사료가치에 미치는 영향을 알아보기 위해 수행되었다. 알팔파는 개화 10% 시기에서 수확되었으며 수분 함량(M60, M50, M40 및 M30)이 60, 50, 40 및 30%일 때 각각 이용하였다. 1500g을 샘플링한 후, 증류수 10mL을 첨가한 미첨가구(NAD)와 Lactococcus lactis 와 Pediococcus pentosaceus의 혼합물을 증류수(0.1g/10mL)에 1.5 x 1010cfu/g 농도로 희석한 후 접종한 미생물 균주 첨가구(ADD)를 3개월 및 6개월 발효하였다. 수분 및 미생물 첨가제에 따른 연평균 알팔파의 조단백, 중성세제 불용성 섬유 및 산성세제 불용성 섬유에서 차이가 없었다(p>0.05). 모든 발효기간에서 pH는 ADD의 M40에서 가장 낮았다(p<0.05). NAD 처리구에서는 젖산이 M50에서 가장 높았고(p<0.05), ADD 처리군에서는 M40 시험구에서 젖산이 가장 높았다(p<0.05). NAD와 ADD의 M60은 젖산 함량이 다른 수분 함량들에 비해 가장 낮으며(p<0.05) 낙산이 유일하게 검출되었다. 미생물군집의 상대적 풍부도는 ADD 처리구의 M40과 M50에서 Homo LAB (Enterococcus, Lactiplantibacillus, Lacticaseibacillus, Lactococcus, Pediococcus)의 비율이 가장 높았고, Clostridium은 M60에서 가장 높았다.

In this study, the protein content and functional changes in soybeans cultured with Phellinus linteus HN00K9 were analyzed. P. linteus HN00K9 was cultured on soybeans. The crude protein content in soybeans cultured with HN00K9 (PMS) was 41.99%, which was higher than that in soybeans not cultured with the mushroom (UCS). The total free amino acid content in PMS increased to 39,963 mg/100 g, which was higher than that in UCS (36,817 mg/100 g). In particular, in PMS, glutamic acid accounted for 18.5% of the total amino acids at 7,413 mg/100 g. The total polyphenol content in PMS was 2.66 mg GAE/g, which was more than 45% higher than the amount in UCS (1.45 mg GAE/g). Additionally, PMS showed a DPPH radical scavenging activity of 33.3%, which was 3 times higher than that exhibited by UCS (11.5%), reflecting its high antioxidant content. Therefore, the PMS in this study has potential for use as a functional food material.

This study aimed to predict the shelf life of black soybean Sunsik to develop a functional labeling system for the product. The Arrhenius equation was used to calculate the shelf life by examining alterations in the dietary fiber and calcium levels of black soybean Sunsik stored at 25, 35, and 50°C for 0, 6, and 12 months. Dietary fiber and calcium analyses were performed according to the experimental methods specified in the Food Code of the Ministry of Food and Drug Safety. Both black soybean Sunsik (BS) and black soybean Sunsik containing nondigestible maltodextrin and calcium lactate (BSN) exhibited an upward trend in dietary fiber content after 12 months of storage, compared to their initial levels. During storage, the phytate in Sunsik degraded, releasing cations that facilitated the formation of new cross-links between pectic acid and middle lamella, which ultimately increased dietary fiber content. Conversely, the calcium contents of both BS and BSN decreased with prolonged storage. Based on these findings, the expected shelf life of BS and BSN was calculated as 15.65 and 28.34 months, respectively.

본 실험은 마이크로웨이브 처리가 상추 유묘의 생육 변화와 이차대사산물 함량의 변화를 알아보고자 수행되었다. 파종 후 3주째 상추 유묘에 2.45GHz 주파수와 200W의 마이크로 웨이브를 0, 4, 8 및 12초 동안 처리하고, 4주간 식물공장에서 재배한 후 생육 및 성분 분석을 수행하였다. 지하부와 지상부 의 생체중과 건물중, 엽면적, 엽장 및 엽수는 마이크로웨이브 처리시간이 증가할수록 감소하였다. 4초 처리구와 비교하여 12초 처리구에서 chlorophyll a, chlorophyll b 및 총 carotenoids 의 함량이 증가되었으며 총 페놀 함량은 감소하였다. 무처리 구와 비교하여 8초 처리구에서 총 플라보노이드 함량이 감소 하였다. 이러한 결과들은 산화적 스트레스에 의해 이차대사 산물 함량이 변화된 것으로 사료된다. 총 플라보노이드 함량 을 제외한 이차대사산물 함량은 각 처리구에서 무처리구와 비 교하여 유의한 차이가 없었지만, 각 처리구 사이의 유의한 차 이는 200W와 2.45GHz의 마이크로웨이브 처리가 4주 후 상 추의 이차대사산물 함량에 영향을 줄 수 있다는 것을 시사한다.

K-콘텐츠의 성장을 단지 문화적 현상 및 경제적 효과라는 측면으로 국한할 수 있을까. K-콘텐츠에 대한 세계적 파급력은 분명 대외적 관 계 및 경제성과를 넘어 공동체에 특정한 영향력을 미치고 있다. 이에 본 논문에서는 대중문화 콘텐츠의 사회자본 가치에 관하여 고찰하였다. 본 논문에서는 대중문화 콘텐츠는 과연 사회자본 가치 형성에 기여하 고 있는 것인지에 관하여 분석하였다. 본고는 사회자본에 관한 이론적 고찰을 통해 대중문화 콘텐츠 중 방탄소년단(BTS)의 활동을 통해 사회 자본 가치를 신뢰, 규범 및 가치, 네트워크라는 3개 요소로 분석하였 다.

견과류는 영양가가 우수하고 다양한 기능성 생리활성을 가져 건강한 식단에 중요한 요소이다. 멜라토닌은 뇌의 송 과선에서 분비되는 호르몬으로 각종 조직의 산화적 손상을 방지하는 것으로 알려져 있으며, 식물체에서도 중요한 역할 을 한다. 본 연구는 견과류의 멜라토닌 추출 및 정량을 위 한 분석법을 마련하였고, 견과류의 높은 지방함량을 고려한 최적화된 추출 절차를 이용하여 경기도에서 유통되는 견과 종실류 등의 멜라토닌 함량을 조사하였다. 땅콩 또는 견과 류, 유지종실류 및 두류의 평균 멜라토닌 함량은 각각 1200.83 (409.76-2223.56), 934.83 (454.10-1736.60), 616.46 (494.70- 825.12) pg/g으로 나타났다. 호두와 밤의 경우 속껍질을 포 함한 반탈각 상태와 과실만 있는 경우의 멜라토닌 함량을 비교한 결과, 반탈각 상태에서 멜라토닌 함량이 유의적으로 높았다. 또한 호두, 밤 및 땅콩의 경우 2022년 재배된 햇 견 과보다 2021년 재배 후 저장된 견과에서 멜라토닌 함량이 유의적으로 높았다. 이러한 결과는 견과종실류 등의 멜라토 닌 함량이 높아 우수한 기능성 식품임을 시사하였다.

본 연구에서는 경기도내 유통되고 있는 심해성 어류 50 건을 대상으로 수은, 메틸수은의 오염도 및 셀레늄의 함 량을 알아보았다. 금아말감법의 수은분석기, ICP-MS를 사 용하여 측정하였으며 각 항목별 평균함량은 수은 0.7647 mg/ kg (0.0182-5.3620), 메틸수은 0.0764 mg/kg (0.0096-0.8750), 셀레늄 0.4728 mg/kg(0.1075-3.5100)으로 메틸수은은 50건 모두 기준규격(1.0 mg/kg) 이하로 나타났다. 셀레늄은 수 은과 결합하여 수은의 독성을 감소시키는 것으로 알려져 있으며, 본 연구과제에서는 일일평균섭취량이 3.3 μg/kg으 로 일일권장량보다 낮은 수치였다. 유해물질인 수은과 메 틸수은은 JECFA에서 설정한 PTWI의 5.7%, 1.8%로 조사 되었다. 따라서 도내에서 유통되는 심해성 어류의 수은, 메틸수은과 같은 위해중금속은 안전한 것으로 나타났지만 지속적 모니터링이 필요하다고 판단된다.

In order to start decommissioning domestic nuclear facilities, the Final Decommissioning Plan (FDP) must be prepared and approved by the regulatory agency. The contents of domestic FDP consist of 12 chapters, and there is the decommissioning feasibility design that should be described in Chapter 5 as contents to be considered from the construction stage of nuclear facilities. The design of decommissioning feasibility for nuclear facilities seems to be largely divided into three items. In summary, there ae minimization of contaminations to facilities and the environment, easy of dismantling, and minimization of the radioactive waste generation. In addition, the design characteristics to which the ALARA principle is applied in terms of optimizing the exposure dose of workers and residents may also correspond to the decommissioning feasibility design. The design characteristics for decommissioning feasibility during the period leading up to the design, operation, and decommissioning of nuclear facilities can be listed as the main points as follows. Minimization of facility contamination will include contents related to the leakage of systems and components, minimization of effluents to the environment will involve gaseous and liquid effluents from systems and components to the environment, easy of dismantling will involves history and inspection records during operation, and minimization of radioactive waste generation can be the contents related to the radioactive waste management plans. The design characteristics of facilities and equipment to meet the ALARA principles can be listed as follows. It means taking into account the benefits and costs of the design improvement plan, and the elimination of unnecessary radiation exposure can be maintained at the exposure dose ALARA, which is in line with the decommissioning feasibility design. Among the requirements of licensing documents for decommissioning domestic nuclear facilities is the decommissioning feasibility design. This item relates to the design characteristics for decommissioning considered in the construction stage of the facility and should present the effectiveness of measures for them until operation and decommissioning. In this study, the regulatory requirements presented in the construction and operation stage and the contents presented in the U.S. case were reviewed, and it is hoped that it will be used as reference for the preparation of FDP.

This study was aimed to determine the effects of grow media on the mineral contents of the leaves and growth characteristics of strawberry grown under aquaponics system in a plant factory. For aquaculture, 12 fish (Cyprinus carpio) (total weight, 2.0 kg) were raised in an aquaponics tank (W 0.7 m × L 1.5 m × H 0.45 m, 472.5 L) filled with 367.5 L of water at a density of 5.44 kg·m-3 and total 34 of strawberry seedlings were transplanted in the pots filed with 200 g of orchid stone, hydroball or polyurethane sponge in the growing bed (W 0.7 m × L 1.5 m × H 0.22 m) laid out with holly acrylic sheet (140×60 mm, Ø80) on the top of the system. The pH and EC of the aquaponic solution was ranged from 7.6 to 4.9 and 0.24－0.91 dS·m-1, respectively. The concentration of NO3-N was about 28% lower than that of the hydroponic standard solution, and K, Fe and B were 10, 27 and 3.8 times lower, respectively; however, the mineral contents of strawberry leaves were in the appropriate ranges with lower contents in the leaves grown with sponge media. The organic content (OM), nitrogen (N), phosphorus (P), and potassium (K) of the sludge were 61.5, 5.72, 8.92, and 0.24%, respectively. The leaf area, leaf number, and dry and fresh weights of shoot at 81 DAT were significantly higher in the hydroball, and the average number of fruits per plant was significantly higher in both the orchid stone and hydroball. There was no significant difference in the fresh and dry weights of fruits. Integrated all the results suggest that the orchid stone and hydroball media are more effective to utilize nutrients in solid particles of aquaponic solution, compared to the polyurethane sponge.

Isoflavones found in soybeans are present as glycosides and aglycones, which differ according to their chemical structure. The absorption rate and bioavailability of aglycones are greater than those of glycosides. It is known that aglycone isoflavones in soybean was converted from glycoside isoflavones by activating of endogenous β-glucosidase under drying (40~60℃) conditions after soaking. In this study, we compared and analyzed the proximate composition and isoflavone contents of soybean powders prepared under dried after soaking were analyzed. In the comparison of the proximate compositions, the moisture contents of white soybean powder dried after soaking (WSPDS) and black soybean powder dried after soaking (BSPDS) were decreased as compared with those of the control white soybean powder (CWSP) and control black soybean powder (CBSP). Whereas the contents of other proximate compositions were increased. The aglycone isoflavone contents were higher in WSPDS than in CWSP. Whereas the aglycone isoflavone contents of BSPDS had a similar content those of CBSP because of the component characteristics of black soybean. In conclusion, we believe that it is appropriate to identify and utilize the component characteristics of soybean varieties in order to induce an increase in the functional component content of soybeans under drying conditions after soaking.
