권은주 ( Eun Ju Kwen ) 대구사학회 2014 대구사학 Vol.116 No.-

This essay is a research to the epitaphs of Go Heum-deok and Go Won-mang. They were father and son, and their epitaphs are an important source that can find the change of life and cognition for many generations than a personal epitaph. Especially, the change of their consciousness was affected by changes to relation between Balhae(渤海) and Tang(唐), and it has various meanings. The family ofGo Heum-deok seems to go to the Tang after the fall of Goguryeo. They were occupied mainly with military action to the northern races in Maknam(漠南), Habuk(河北) and Yoseo(遼西). The army that led by them was mainly the displaced of Goguryeo. They seemed to have been a consciousness that derived from Goguryeo than the displaced of Goguryeo in central Tang. They must have been thought to themselves that derived from Balhae. However, the relation between Tang and Balhae has beenin state of war since 730s, they were difficult to show a consciousness about their race. As a result, the family of Go Heum-deok put Bigan(比干) of Chinese descent up for their founder. But their consciousness was confused with consciousness of Seochal(徐察), a next generation, and the epitaph of Go Won-mang was expressed that he had relation to Go of Balhae, regardless of Bigan.

Reduction by Coenzyme Q_10 of Adriamycin-Induced Hematotoxicity in Rats

Kwen, Yong-Zun 대구효성가톨릭대학교 1981 연구논문집 Vol.23 No.3

Rat에 Adrianmycin을 계속 주사하면 血球數, hematocrit 및 Hemogloin 농도가 減少한다. Adriamycin과 同時에 CoQ_10을 주사하면, hematocrit 및 hemoglobin 濃度 減少는 完全히 防止할 수가 있다. 赤血球數와 白血球數가 CoQ_10에 의해서 약간 減少하거나 전연 減少되지 않는 點에서 예시되는 바와 같이, CoQ_10은 Adriamycin에 의해서 생긴 bone marrow suppression을 감소시킬 수 있는 可能性이 있다. Continuous injection of adriamycin to rats causes reproducible suppression of blood cells count, hematocrit, and hemoglobin concentration. Concomitant administration of coenzyme Q_10 with adriamycin offered a total prevention of the fall in hematocrit and hemnglobin concentation. The coenzyme Q_10 is also promising in alleviation of adriamycin-caused bone marrow suppressin as is suggested by smaller or no depression by the coenzyme of the counts of both crythrocytes and leucocytes.

Rescue by CoQ_10 of hematological changes induced by Adriamycin in rats

KWEN, YONG ZUN 韓國自然史博物學會 1980 生物과 自然 Vol.10 No.1

With cumulative dose up to 15mg/kg, adriamycin did not affect red blood cell count (RBC count), hematocrit readings, hemoglobin level and plasma protein concentration. In contrast, the drug was able to reduce white blood cell (WBC) counts and reduce growth of body weight and even though statistically insignificant as yet, some change in other parameter could be possible with higher cumulative dose of the drug. The redced level of WBC by ADM was, to some extent, reversed by concomitant admintration of either CoQ_10 or vitamin E acid succinate. 항암제인 Adriamycin을 흰쥐의 體重 Kg當 15mg까지의 Cumulative dose(3 week동안)로 Intraperitoneal injection으로 투여할때, 赤血球數, hematocrit, hematocrit level 및 plasma protein 濃度에는 影響을 미치지않으나, 白血球數 및 體重은 현저히 減少시켰다. Adriamycin에 의해서 줄어드는 白血球의 數는 CoQ_10이나 Vitamin E를 Adriamycin과 同時에 투여하므로써, 어느정도 增加시킬 수 있었다.

Preparation and Characterization of an Electrogenerated Chemiluminescence Sensor by Electrochemical Grafting of 4-Nitrophenyl Diazonium Salts Onto a Glass Carbon Electrode

Kwen, Hai-Doo,Oh, Sang-Hyub,Choi, Seong-Ho American Scientific Publishers 2012 Journal of Nanoscience and Nanotechnology Vol.12 No.7

<P>An ECL sensor was fabricated by immobilization of a tris(2,2'-bipyridyl)ruthenium (II) complex (Ru(bpy)3(2+)) to an amine group-modified GC electrode (NH2-GC electrode). Here, the NH2-GC electrode was prepared by electrochemical reduction of a nitro group-modified GC electrode in 0.1 M KCl ethanol solution under H2 gas, which was followed by electrochemical grafting of 4-nitrophenyl diazonium salts in 0.1 M NBu4BF4 acetonitrile solution onto the GC electrode. The prepared ECL sensor was successfully confirmed via cyclic voltammetry, contact angle, scanning electron microscopy (SEM), energy dispersive spectrometry (EDS), and ECL spectrometry. The contact angle for the surface of the GC electrode, NO2-GC electrode, and NH2-GC electrod was 88.4 degrees, 67.4 degrees, and 52.4 degrees, respectively. The stability of the ECL sensor was investigated under continuous cyclic potential scanning for 55 cycles and the ECL intensity remained at 55%. The prepared ECL electrode can be expected to immobilize enzymes for preparation of the ECL biosensor to detect target molecules.</P>

Fabrication of Non-Enzymatic Biosensor Based on Metallic Catalyst-TiO₂ Hollow Sphere Nanocomposite for Determining Biomolecules

Kwen, Hai-Doo,Yang, Hee-Soo,Lee, In-Ho,Choi, Seong-Ho American Scientific Publishers 2012 Journal of Nanoscience and Nanotechnology Vol.12 No.7

<P>A PtRu@TiO2-hollow nanocomposite for the detection of biomolecules was synthesized by chemical reduction. First, poly(styrene-co-vinylphenylboronic acid), PSB, was prepared as a template (approximately 250 nm) by surfactant-free emulsion polymerization. Second, PSB/TiO2 core-shell spheres were prepared by sol-gel reaction. Finally, TiO2 hollow spheres (TiO2-H) were then formed after removing the PSB template by calcination at 450 degrees C under air atmosphere. To prepare the electrocatalyst, PtRu nanoparticles (NPs) were deposited onto the TiO2-H surface by chemical reduction. The prepared PtRu@TiO2-H nanocomposite was characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), and elemental analysis. A non-enzymatic sensor was fabricated by depositing the as-prepared PtRu@TiO2-H nanocomposite on the surface of a glassy carbon electrode (GCE), which was prepared by a hand casting method with Nafion solution as a binder. The sensor was tested as a biomolecule sensor, especially for the detection of glucose and dopamine. The cyclic voltammograms (CV) obtained during the oxidation studies revealed that the PtRu@TiO2-H nanocomposite showed better catalytic function toward the oxidation of dopamine. The sensing range of the non-enzymatic sensor for glucose was 5.0-100 mM in a phosphate buffer. The results demonstrated the potential usefulness of this bimetallic@TiO2-H bifunctional catalyst for biosensor applications.</P>

Kwen Hwayoung,오복자 한국간호과학회 2022 Asian Nursing Research Vol.16 No.5

Purpose: This study aimed to develop a mobile web-based food allergy (FA) and anaphylaxis management educational program for parents of school-aged children with food allergies and evaluate its effectiveness. Methods: A mobile program was developed based on a web-based teaching-learning system model. Its effectiveness was subsequently evaluated using a parallel, randomized controlled pre- and post-test design. This study included 73 parents of school-aged children with food allergies. These parents were randomly assigned to either the experimental (n ¼ 37) or control (n ¼ 36) groups. The experimental group participated in a 2-week mobile web-based educational program that covered major topics in FA and anaphylaxis management. These topics included an understanding of food allergies and anaphylaxis, learning techniques for using an epinephrine auto-injector, and developing an emergency action plan. An educational booklet was provided to the control group. Participants completed a pre-test and two posttest questionnaires to evaluate the impact of the program. The assessment tools were the Food Allergy Knowledge Test, Food Allergy Self-Efficacy for Parents, and Food Management and Adaptation Scale. The data were analyzed using descriptive statistics, a test of homogeneity for the pre-test, an independent ttest, and repeated measures ANOVA. Results: The experimental group experienced greater improvement in the knowledge of FA (postintervention t ¼ 14.51, p < .001; 2 weeks post-intervention, t ¼ 16.15, p < .001), FA self-efficacy (postintervention t ¼ 77.99, p < .001; 2 weeks post-intervention, t ¼ 76.09, p < .001), and practice behavior in FA management (post-intervention t ¼ 28.10, p < .001; 2 weeks post-intervention, t ¼ 27.98, p < .001) after web-based FA education. Conclusion: This study revealed improvements in the knowledge, self-efficacy, and practice behaviors of parents regarding FA and anaphylaxis management. Therefore, the mobile web-based educational program can contribute to the effective management of food allergies and anaphylaxis for parents of schoolaged children. CRIS registration: KCT0007491.

唐代 營州 출신 고구려계 高英淑의 묘지명 검토

권은주(Kwen, Eun-Ju) 한국고대사학회 2016 韓國古代史硏究 Vol.0 No.84

앞으로 隋 · 唐代 營州(현 중국 朝陽) 지역에서 발견되고 있는 묘지명을 주목할 필요가 있다. 이들 묘지명 중에는 개인적인 정보 외에도 해당 지역의 동향과 고구려 · 발해와의 관계에 대한 정보들이 상당하기 때문이다. 이 글에서는 高英淑 묘지명을 살펴보았다. 고영숙 묘지명은 진위여부가 확실한 자료로, 그녀의 계통과 사회적 지위에 대해 중요한 정보를 제공하고 있다. 고영숙은 중국학계에서 거란족으로 알려졌다. 그러나 ‘昌黎 孤竹人’과 ‘高辛氏’를 출자로 내세운 점이나 고구려계 高雲의 후예로 자처한 점을 통해 고구려계임을 알 수 있다. 고영숙은 당시 營州 지역에서 상당한 사회적 지위를 지닌 여성이었다. 고영숙의 묘지명과 무덤의 규모 및 격식은 영주 지역에서 발견되는 것 중 1등급에 속한다. 묘지명에 남편에 대한 정보가 없는 점은 그녀의 사회적 지위에 남편의 영향이 크지 않았기 때문일 것이다. 고영숙의 친가가 시가를 압도하는 高門이었고, 고영숙은 사망 무렵 집안의 宗婦이자 家長이면서 遼西府에 상당한 영향력을 행사하는 위치에 있었던 것으로 생각된다. 夫人 앞에 칸을 띄워 공경을 나타내고, 남성에게 주로 사용되던 미사어구들을 사용한 것은 고영숙이 단순히 한 집안의 여성 가장이 아님을 보여준다. 더불어 일찍이 요서지역으로 이주했었던 고구려계인 고영숙 묘지명은 고구려 멸망 전후 고구려인들의 출자 의식 표기와 차이를 보이고 있어 향후 비교연구에 유용하리라 본다. 그리고 남성중심의 가부장제가 발달하는 과정에서의 여성 지위, 특히 북방 지역여성의 지위 연구에도 좋은 자료가 된다. We need to take note of the epitaphs being found in Youngju(營州) region(current Chaoyang of China) of Sui and Tang dynasty. Besides a lot of individual information, These epitaphs are very valuable materials because they have regional information and much Goguryeo and Balhae related information This paper examined the epitaph of Ko Youngsook(高英淑). The authenticity of this epitaph is surely proved, so it provides good information about her line and social status. Ko Youngsook has been known as Khitans(契丹) in the Chinese academic world. But we can know that she was Goguryeo decent because she was described as Changryo Kojookin(昌黎 孤竹人), Ko Woon(高雲) and Kosinsi(高辛氏) meaning progenitor in the epitaph. At that time, Ko Youngsook was a woman holding a fairly high social position. The epitaph, size and formality of Ko Youngsook’s tomb belong to the first grade among the tombs being found in Youngju region. Because her husband’s influence on her social status was insignificant, there is no information about her husband in the epitaph. Her father’s side of family was eminent one and she was on a high position able to exercise her influence over Yoseoboo(Yoseoboo-capital, 遼西府) by the time of her death as the first daughter-in-law(宗婦) and head of her family(家長). Making a blank to show respect before the word ‘Boo-in’(wife, 夫人) and using flowery words used in man’s tomb at that time were not just because she was the head of her family. Namely, the reverent and flowery words of the epitaph reflect the owner’s status and influence. In addition, the epitaph of Ko Youngsook is valuable to compare the rites for progenitor between Goguryeo decent moved into Yoseo(遼西) province early and Goguryeo people moved into Yoseo province about the collapse of Goguryeo. And it is a good resource to study the woman’s status in the developmental process of male-dominated patriarchy, especially the woman’s status in the northern area.
