사이잘삼을 이용한 조각보 이미지의 입체적 표현 연구

권유현,나지영 한국기초조형학회 2004 기초조형학연구 Vol.5 No.4

In the later part of 20th century, escaping from the strictness of modernism, contemporary art has expressed free and innovative ideas in postmodernism, the global and universal tendency. The scale and range of artworks have been extended beyond the reality, allowing images through metaphor and symbol and showing you a lot to think about in the artwork.In this environment, fiber art also has been changed a lot worldwide and experimental fiber arts are introduced by many world-leading artists. Arts of postmodernism can be found in Korea that show the trials to find our own identity in the age of radical changes. One of such trials is the activity to rebuild our traditional arts to modern and global ones. For example, arts that revive or include the image of wrapping cloth (Bo-Ja-Gi) appear in various forms, not just in the area of applied fine arts but also in the area of fine arts.In this paper, different from the existing way of approach, I tried to express the great forms and humble spirits of chogak po with creative images that common women of Lee Dynasty presented, by focusing on formative expression on our traditional chogak po image. With the idea that the feeling of vegetable fiber such as ramie or hemp can be expressed in chogak po, the plane form, I expressed the relief 3D form using Sisal hemp. In color, to express the single color image of ramie or hemp chogak po, I tried to make soft and nature-friendly one with the experiment of nature dyeing using black tea. 20C후반 현대미술은 포스트모더니즘이라는 사회 전반적이며 세계적인 흐름 속에서 모더니즘에서의 여러 가지 엄격한 구분이나 예술의 각 장르간의 폐쇄성으로부터 벗어나 혁신적이고 자유로운 표현을 구현하여 왔다. 작품의 규모나 범위를 확장시켜 나아갔으며 보이는 것만이 아니라 은유와 상징을 통한 이미지를 허용함으로써 작품 속에서 생각할 많은 것들을 보여주려 하였다. 이러한 기류 속에서 섬유예술 분야 역시 세계적으로 혁신적인 변화를 가져왔으며 세계적인 여러 작가들을 통해 실험적인 섬유작품들이 선보이고 있다. 국내에서도 포스트 모더니즘적인 작품들을 볼 수 있는데, 이런 급진하는 변화 속에서도 우리의 정체성을 찾고자하는 노력을 엿볼 수가 있다. 우리의 옛것을 찾아 현대적이고 세계적인 것으로 재 확립시키고자하는 여러 작가들의 활동이 그 중 하나이다. 대표적인 예로 조선시대 보자기의 이미지를 작품 속에 도입시키는 예술작품들이 공예분야에서는 물론, 회화분야에서도 무척 다양한 형태로 나타나고 있다. 본 연구자는 이 논문에서 우리의 전통 조각보의 이미지를 기존의 표현양식과는 다른 조형적 표현 연구를 통해, 조선시대 여인들이 조각보에서 보여주고 있는 우수한 조형성과 더불어 서민적인 조각보 정신을 독창적 이미지로 표현하고자 하였다. 또한 평면적 조형물인 조각보를 식물성 섬유인 모시나 베의 느낌을 표현할 수 있다는 점을 생각하여 사이잘삼을 이용한 부조적인 입체조형으로 표현하였고, 색상에 있어서는 모시 조각보나 베 조각보에서 많이 보여 지는 단색 조각보의 이미지를 표현하기 위해 홍차를 이용한 천연염색실험을 통해 은은하면서도 자연 친화적인 색상을 만들어 내고자 하였다.

The first treatment option for secondary trigeminal neuralgia: open surgery versus stereotactic radiosurgery

권유현,노해원,김종현 대한정위기능신경외과학회 2023 대한정위기능신경외과학회지 Vol.19 No.2

Trigeminal neuralgia (TN) is a condition involving oro-facial pain that causes patients to suffer and significantly impacts their quality of life. TN can generally be classified into three categories: classical, secondary, and idiopathic. Among these, secondary TN, which accounts for approximately 15% of cases, is attributed to identifiable neurologic diseases such as tumors and multiple sclerosis. Although the clinical features of classical and secondary TN are similar, secondary TN should be treated individually based on its underlying pathology. This paper presents a case of secondary TN induced by meningioma. The patient underwent Gamma Knife radiosurgery twice but showed no improvement in symptoms, ultimately leading to surgical removal of the tumor. The diagnosis-to-surgery time was 2 years. This case report discusses the first-line treatment options for secondary TN, with a focus on symptom relief.

Background: Hypertriglyceridemia is known to have an association with increased risks of insulin resistance and diabetes. The aimof this study was to investigate the risk of diabetes mellitus, according to changes in the concentrations of triglycerides, over time. Methods: A total of 15,932 non-diabetic participants (mean age 43.2 years, 68% men) who attended five consecutive annual healthcheck-ups at Kangbuk Samsung Hospital, between January 2010 and December 2014, were recruited. Participants were classifiedaccording to their triglyceride concentrations; normal (<150 mg/dL) and abnormal (≥150 mg/dL). According to the triglyceridelevels in 2010 and 2012, subjects were divided into four groups: normal-normal, normal-abnormal, abnormal-normal, and abnormalabnormal. The risk for incident diabetes was assessed in 2014. Results: Among the total subjects, 67.5% belonged to the normal-normal group, 8.6% to the normal-abnormal group, 9.4% to theabnormal-normal group, and 14.5% to the abnormal-abnormal group. A total of 234 subjects (1.5%) were newly diagnosed with diabetes,between 2010 and 2014. Over 4 years, 1%, 1.5%, 2.1%, and 3.0% of the subjects developed diabetes in the normal-normal,normal-abnormal, abnormal-normal, and abnormal-abnormal groups, respectively. When the risk for incident diabetes was analyzedin the groups, after adjusting the confounding variables, a 1.58-fold increase in the risk of diabetes (95% confidence interval [CI],1.10 to 2.26) was observed in the participants with persistent hypertriglyceridemia (abnormal-abnormal group). This was attenuatedby further adjustments for body mass index (BMI) (hazard ratio, 1.25; 95% CI, 0.86 to 1.80). Conclusion: In this large study population, persistent hypertriglyceridemia, over a period of 2 years, was significantly associatedwith the risk of incident diabetes, which was attenuated after adjustment for BMI.

This study was conducted to investigate the antioxidant activities and physiological properties of Euphorbia humifusa extracts prepared using three different solvents (water, ethanol, and methanol). The highest total polyphenol content (293.25 mg/100 g) and total flavonoid content (21.05 mg/100 g) were observed in the methanol extract. The content of substances related to proanthocyanidin were highest in the water extract (8.42 mg/100 g), followed by methanol (5.70 mg/100 g) and ethanol (5.39 mg/100 g) extracts. The DPPH and ABTS radical scavenging activities of the methanol extract were 91.72% and 85.83%, respectively, at 50 mg% concentrations, which were higher than those of the other extracts. The extract reducing power decreased in the following order: ethanol > methanol > water. The methanol extract had relatively high antioxidant activity. The α-glucosidase and xanthine oxidase inhibitory activities of the methanol extract at a concentration of 10 mg% were somewhat higher than the other extracts. HMG-CoA reductase inhibitory activity in the water extract was slightly higher than in the methanol and water extracts. These results indicated that Euphorbia humifusa extracts were a high-value food ingredient due to their antioxidant activities and nutritional value.

알루미늄 합금 압출재(Al 6xxx계)의 응력부식균열(SCC) 거동

이정화,권유현,김상호 한국표면공학회 2009 한국표면공학회 학술발표회 초록집 Vol.2009 No.-

최근 경량화, 리사이클성, 기기의 소형화, 내환경성 등의 이점을 가지고 있는 알루미늄 합금이 여러 분야서 재인식 되고 있다. 그러나 이런 알루미늄 합금이 부식 환경에 노출 될 경우 응력부식균열이 발생할 수 있게 된다. 이러한 응력부식균열의 발생은 알루미늄의 기계적 특성에 안 좋은 영향을 미치므로 제품의 품질저하, 수명 단축, 효율저하, 재해발생 등 직간접적으로 광범위한 피해를 입게 되기에 부식에 대한 많은 연구가 진행이 되고 있다. 이 중에 고비강도용 알루미늄 압출소재인 Al 6xxx계 합금의 열처리 및 조성 변화에 따른 응력부식균열의 거동에 대해 연구하였다. 응력부식균열 시험은 SSRT시험으로 많이 하고 있는데, 이 시험은 인장시편을 부식 환경 하에 노출하면서 천천히 일정한 변형속도로 당기는 시험이다. 본 연구에서는 Strain rate를 10<SUP>-6</SUP>s<SUP>-1</SUP>, 부식용액은 1M-NaCl + 0.6M-Na₂SO₄ + 0.3%-H₂O₂을 사용하여 시험을 하였다. 그리고 시험에 대한 분석은 Tafel polarization curve, SEM, OMS를 이용하였다.

Background: Age-related decreases in lean mass represent a serious health problem. We aimed to analyze the risks of rapid decreases in lean mass by age and sex in relatively young Korean adults during a 4-year follow-up study. Methods: A total of 65,856 non-diabetic participants (59.5% men, mean age 39.1 years) in a health screening program were subjected to bioimpedance body composition analyses and metabolic parameter analyses at baseline and after 4 years. The participants were sub-divided according to age, and additionally to six groups by age and the degree of body weight change over the 4-year period. The actual changes in body weight, lean mass, and fat mass and the percent changes over the 4-year period were assessed. Results: The percent change in lean mass decreased and the percent change of fat mass increased with increasing age in every age and sex group. However, the annual percent decrease in lean mass and percent increase in fat mass were significantly higher among women than among men (–0.26% vs. –0.15% and 0.34% vs. 0.42%, respectively; P<0.01). Participants who were older than 50 years and had a weight loss <–5% during the 4 years had significantly greater decreases in lean mass and smaller decreases in fat mass, compared to those who were younger than 50 years. An odds ratio analysis to determine the lowest quartile of the percent change in lean mass according to age group revealed that participants older than 60 years had a significantly increased risk of a rapid decrease in the lean mass percentage (2.081; 95% confidence interval, 1.678 to 2.581). Conclusion: Even in this relatively young study population, the lean mass decreased significantly with age, and the risk of a rapid decrease in lean mass was higher among women than among men. Furthermore, the elderly exhibited a significantly more rapid decrease in lean mass, compared with younger participants.
