오유나,김주덕 한국인체미용예술학회 2024 한국인체미용예술학회지 Vol.25 No.4

This study aimed to explore the appearance management orientation and beauty interests of Generation MZ women, who have driven changes and consumer trends in the beauty industry. To achieve this, a survey was conducted targeting Generation MZ women from May 14 to June 15, 2024, using an online questionnaire. Out of 380 questionnaires distributed, 350 were collected, excluding those with inadequate responses. The collected data were analyzed using reliability analysis, frequency and percentage analysis, cross-tabulation, t-tests, one-way ANOVA, correlations, and multiple regression analysis. The results revealed the following: First, the average appearance management orientation was 3.37 out of 5, indicating a moderate level. Second, interest in beauty averaged 3.56 out of 5, reflecting a higher level of engagement. Third, a significant relationship was found between appearance management orientation and beauty interest (p<.001, p<.01, p<.01). These results suggest that as the level of appearance management orientation among Generation MZ women increases, their interest in beauty also rises. This indicates that appearance management orientation positively influences beauty interest, emphasizing the psychological motivation of this generation to enhance their appearance. Consequently, there is a need for marketing and promotional strategies that not only meet MZers’ beauty interests but also encourage their engagement in beauty management practices.

오유나,김연학,김지훈,김은석,이병렬,양기영 경락경혈학회 2022 Korean Journal of Acupuncture Vol.39 No.4

Peripheral facial palsy generally results from damage to the facial nerve. As facial asymmetry is observed, it accompanies not only functional problems but also psychological and social difficulties. Medical institutions treat most patients, however, there are still patients who rely on invasive methods by unqualified practitioners for fear of sequelae. This case describes a 61-year-old woman who experienced facial palsy twice. She visited our hospital with skin damage after folk patch therapy for her facial palsy. Combined Korean medicine treatment was administered during treatment period. After treatments, the symptoms of facial palsy and skin lesions improved. This case showed that Korean Medicine was efficacious in improving symptoms of facial palsy with damaged skin caused by folk patch therapy. Education and awareness of uncontrolled invasive treatments for facial palsy are needed.

사용후핵연료 심지층 처분장의 완충재 소재인 WRK 벤토나이트의 pH 차이에 따른 우라늄 흡착 특성과 기작

오유나,신대현,김단우,전소영,김선옥,이민희 대한자원환경지질학회 2023 자원환경지질 Vol.56 No.5

사용후핵연료(Spent nuclear fuel; SNF) 심지층 처분장의 완충재 소재로서 WRK (waste repository Korea) 벤토나이트가 적합한지를 평가하기 위하여, 대표적인 방사성 핵종인 U (uranium)에 대한 WRK 벤토나이트의 흡/탈착 특성과 흡착 기작을 규명하는 다양한 분석, 흡/탈착 실내 실험, 동역학 흡착 모델링을 다양한 pH 조건에서 수행하였다. 다양한 특성 분석 결과, 주성분은 Ca-몬모릴로나이트이며, U 흡착 능력이 뛰어난 광물학적·구조적 특징들을 가지고 있었다. WRK 벤토나이트의 U 흡착 효율 및 탈착율을 규명하기 위한 흡/탈착 실험 결과, pH 5, 6, 10, 11 조건에서 WRK 벤토나이트와 U 오염수(1 mg/L)가 낮은 비율(2 g/L)로 혼합되었음에도 불구하고 높은 U 흡착 효율(>74%)과 낮은 U 탈착율(<14%)을 보였으며, 이는 WRK 벤토나이트가 SNF 처분장에서 U 거동을 제한하는 완충재 소재로서 적절하게 사용될 수 있음을 의미한다. pH 3과 7 조건에서는 상대적으로 낮은 U흡착 효율(<45%)이 나타났으며, 이는 U가 용액의 pH 조건에 따라 다양한 형태로 존재하며, 존재 형태에 따라 상이한 U 흡착기작을 가지기 때문으로 판단된다. 본 연구 실험 결과와 선행연구를 바탕으로 WRK 벤토나이트의 주요 화학적 U 흡착 기작을 pH 범위에 따라 용액 내 U의 존재형태에 근거하여 설명하였다. pH 3 이하에서 주로 UO22+ 형태로 존재하는 U는 벤토나이트 표면의 Si-O 또는 Al-O(OH)와의 정전기적 인력(예: 이온 결합)에 의해 흡착되기 때문에 pH가 감소할수록 음전하 표면이 약해지는 WRK 벤토나이트 특성에 의해 비교적 낮은 U 흡착 효율이 나타났다. pH 7 이상의 알칼리성 조건에서 U는 음이온 U-수산화 복합체(UO2(OH)3-, UO2(OH)42-, (UO2)3(OH)7- 등)로 존재하며 비교적 높은 흡착 효율이 나타내는데, 이들은 벤토나이트에 포함된 Si-O 또는 Al-O(OH)의 산소원자를 공유하거나 리간드 교환에 의해 새로운 U-복합체가 형성되어 흡착되거나 수산화물 형태의 공침(co-precipitation)에 의해 벤토나이트에 고정되기 때문이다. pH 7의 중성 조건에서는 pH 5와 6보다 오히려 낮은 U 흡착 효율(42%)이 나타났는데, 이러한 결과는 용액 내 존재하는 탄산염(carbonate)에 의해 U가 U-수산화 복합체보다 용해도가 높은 U-탄산염 복합체로 존재하는 경우 가능하다. 연구 결과 pH를 약산성 또는 염기성 조건으로 유지하거나 용액 내 존재하는 탄산염을 제한함으로써 WRK 벤토나이트의 U 흡착 효율을 높일 수 있는 것으로 나타났다. This study focused on evaluating the suitability of the WRK (waste repository Korea) bentonite as a buffer material in the SNF (spent nuclear fuel) repository. The U (uranium) adsorption/desorption characteristics and the adsorption mechanisms of the WRK bentonite were presented through various analyses, adsorption/desorption experiments, and kinetic adsorption modeling at various pH conditions. Mineralogical and structural analyses supported that the major mineral of the WRK bentonite is the Ca-montmorillonite having the great possibility for the U adsorption. From results of the U adsorption/desorption experiments (intial U concentration: 1 mg/L) for the WRK bentonite, despite the low ratio of the WRK bentonite/U (2 g/L), high U adsorption efficiency (>74%) and low U desorption rate (<14%) were acquired at pH 5, 6, 10, and 11 in solution, supporting that the WRK bentonite can be used as the buffer material preventing the U migration in the SNF repository. Relatively low U adsorption efficiency (<45%) for the WRK bentonite was acquired at pH 3 and 7 because the U exists as various species in solution depending on pH and thus its U adsorption mechanisms are different due to the U speciation. Based on experimental results and previous studies, the main U adsorption mechanisms of the WRK bentonite were understood in viewpoint of the chemical adsorption. At the acid conditions (<pH 3), the U is apt to adsorb as forms of UO22+, mainly due to the ionic bond with Si-O or Al-O(OH) present on the WRK bentonite rather than the ion exchange with Ca2+ among layers of the WRK bentonite, showing the relatively low U adsorption efficiency. At the alkaline conditions (>pH 7), the U could be adsorbed in the form of anionic U-hydroxy complexes (UO2(OH)3-, UO2(OH)42-, (UO2)3(OH)7-, etc.), mainly by bonding with oxygen (O-) from Si-O or Al-O(OH) on the WRK bentonite or by co-precipitation in the form of hydroxide, showing the high U adsorption. At pH 7, the relatively low U adsorption efficiency (42%) was acquired in this study and it was due to the existence of the U-carbonates in solution, having relatively high solubility than other U species. The U adsorption efficiency of the WRK bentonite can be increased by maintaining a neutral or highly alkaline condition because of the formation of U-hydroxyl complexes rather than the uranyl ion (UO22+) in solution, and by restraining the formation of U-carbonate complexes in solution.

오유나,김도연,윤영현,황혜지 한국교육공학회 2025 교육공학연구 Vol.41 No.1

This study established instructional design principles and a teaching model for integrating generative artificial intelligence (AI) to facilitate questioning activities aimed at fostering critical thinking through problem-based learning (PBL). Given the increasing prevalence of generative AI in education, there is a growing need for structured educational support to enable learners to utilize this technology safely and effectively in problem-solving processes while developing critical thinking skills. Employing a design and development research methodology, this study derived initial instructional design principles through a literature review and field interviews, refining them through two rounds of expert validation and field implementation. The final framework comprises ten core principles: (1) familiarization with generative AI, (2) promoting learning engagement through problem redefinition, (3) creating learner-centered environments, (4) individualized exploration, (5) cultivating an ethical attitude toward generative AI, (6) providing question scaffolding, (7) using questioning to enhance critical thinking skills, (8) collaborative learning with generative AI, (9) critically evaluating AI-generated responses, and (10) engaging in critical reflection on the learning process. Based on these principles, a six-stage teaching model was developed and implemented with third-year middle school students. The findings indicate that this model effectively fostered students’ critical thinking skills. This study contributes to educational practice by providing empirically validated design principles for implementing PBL-based questioning activities with generative AI in secondary education settings.

Objective: This long-term case report details a case of pancreatic cancer with lung metastasis suppressed by integrative cancer medicine (IMT). Methods: A 64-year-old woman diagnosed with pancreatic cancer visited a Korean medicine hospital complaining about the side effects of chemotherapy for lung metastasis. She received IMT involving Korean traditional medicine and Western immunotherapy from May 2017 to June 2023. Tumor dimensions were assessed through computed tomography (CT) and positron-emission tomography/CT scans, while tumor markers and safety were monitored by laboratory tests. Results: IMT suppressed the progression of cancer, as observed by imaging and laboratory tests. The patient achieved 5-year survival, even after discontinuing chemotherapy. Conclusion: This case presents a potential therapeutic alternative for patients who are ineligible for chemotherapy or surgical interventions.

인간 폐암 세포주에서 Widdrol에 의한 Apoptosis 유도

오유나,홍윤경,윤희정,이은우,최영현,권현주,김병우,이현태,박철 대한암예방학회 2009 Journal of cancer prevention Vol.14 No.3

Widdrol, a crystalline, natural substance, is an odorant derivative contained in various plants such as the Juniperus sp., including Juniperus chinensis. Though widdrol has been known to possess anti-fungal activity against Botrytis cinerea, anti-cancer properties of widdrol are not well understood. Therefore, we report the cytotoxic activity and the mechanism of cell death exhibited by the widdrol from Juniperus chinensis against human lung carcinoma A549 cells. Treatment A549 cells with various concentrations of widdrol resulted in growth inhibition and apoptosis induction in a dose-dependent manner as determined by cell viability, chromatin condensation, and DNA fragmentation analysis. The Western blot analysis revealed that apoptosis in A549 cells was associated with release of cytochrome c from mitochondria into the cytosol, activation of caspase-3, -8, -9 and proteolytic cleavage of poly (ADP-ribose) polymerase (PARP). These results suggest that widdrol exhibits antiproliferative effect on A549 cells via apoptosis, and can be a potential candidate in the field of anticancer drug discovery.

오유나,김학연 한국축산식품학회 2025 한국축산식품학회지 Vol.45 No.3

This study compared the physicochemical properties of mushroom mycelium before and after rinsing, in addition to the physicochemical and textural properties of sausages with mushroom mycelium added at 0%, 25%, 50%, 75%, and 100% ratios. Physicochemical characteristics included pH, cooking yield, electronic nose, electronic tongue, and sensory characteristics, and textural properties included viscosity, emulsion capacity, and texture. Cooking yield improved and pH significantly decreased (p<0.05) with increasing mycelium content. The electronic nose results identified key compounds, such as propenal, propan-2-one, 2,3-pentanedione, and hexanal. The electronic tongue results showed a trend in which salty, sour, and umami flavor intensity increased with increasing mycelium content. Viscosity tended to decrease with increasing mycelium content. Emulsion capacity was significantly higher in the MM75 treatment group, but significantly lower in the MM100 treatment group (p<0.05). Texture profile analysis showed that as the mycelium content increased, the hardness, cohesiveness, gumminess, elasticity, and chewiness decreased.

20-30대 직장남성의 뷰티헬스케어행동이 외모만족도와 심리적행복감에 미치는 영향 연구

오유나,김세온 한국인체미용예술학회 2025 한국인체미용예술학회지 Vol.26 No.4

This study aimed to investigate the influence of beauty healthcare behaviors on appearance satisfaction and psychological well-being among male office workers in their 20s and 30s. An online survey was conducted from April 18 to May 20, 2025, with 330 questionnaires distributed. After excluding poor responses, 301 valid samples were analyzed. Frequency analysis, chi-square tests, one-way ANOVA, t-tests, and correlation analyses were employed. The results are as follows: First, beauty healthcare practices among male office workers in their 20s and 30s showed significant differences by occupation, with those in sales/service and self-employed sectors demonstrating relatively more active engagement. Second, skincare management behaviors, as a subcategory of beauty healthcare, did not have a statistically significant effect on appearance satisfaction and psychological well-being. However, health management behaviors and cosmetic use behaviors showed statistically significant effects on both, with higher engagement associated with greater satisfaction and well-being. These findings suggest that beauty healthcare behaviors among male office workers in their 20s and 30s extend beyond simple external grooming, serving as an important means of fulfilling psychological needs and self-management. Therefore, it is necessary to foster a stronger market foundation and develop diverse programs that promote sustained interest and correct perceptions of beauty healthcare among men.
