Purpose: The current study aims to identify the effects of proprioceptive neuromuscular facilitation (PNF) on pain and grip strength in patients with cervical herniated intervertebral disc (HIVD) and provide effective interventions for such patients. Methods: Included in this study were 20 subjects (10 men, 10 women) in their 30s-50s who had been diagnosed with cervical HIVD. Intervention methods included PNF neck patterns, dynamic reversal of antagonists, and a combination of isotonics. The visual analogue scale (VAS) was used to measure pain and dynamometers were used to measure grip strength. Results: After four weeks of muscle strengthening exercises, neck pain was significantly reduced, and hand grip strength significantly increased. Conclusion: PNF can be utilized as an effective intervention to reduce the pain of patients with cervical HIVD and to increase grip strength.

김재용(Kim, Jae-yong) 국어국문학회 2014 국어국문학 Vol.- No.168

Korea writers who choose North Korea after emancipation is very important in the unification of North and South Korea. Especially the poet Baik-suk and Novelist Han-Sulya is very important because they spent so long years in North Korea and can not write freely. The poet Imhwa and Novelist Lee-taejun spent so short time in North Korea after escaping from South Korea. So, they are not important in contrast to Baik-Suk and Han-Sulya. The poet Lee-Yongak and the novelist Lee-Kiyoung spent all their life in North Korea aftner emancipation. they had no tension with North Korean state regime. They followed the polictics of government without tension and conflict. Considering these situations, Baik-Suk and Han-Sulya is very important in literary unification of South and North Korea. But there are so many problems in studying these writers in South Korean literary study scene. Now So many scholars who study the poem of Bai-Suk do not want to study the poems of North-Korea because they are the result of state control and censorship of North Korea government. So many scholars who study the work s of Han-Sulya interpret that his works that represent anti-japanese activity of Kim ?Ilsung in Manchuria under the Japanese Empire is the result of personal cult. These kind of attitudes are originated from the consciousness of cold war. To know poet Baik-Suk, we should study all his poems from Japanese Empire period to North-Korea period. It is very ridiculous for scholar to select and study only poems produced in Japanese Empire period. To know novelist Han-Sulya, we should consider historical situation of his work’s production. His works that deal with anti-japanese movement of Kim-Ilsung was created to evoke the historical facts which is concealed from Japanese censorship. It is very different from the works of personal cult that is created from 1967 based on idea of Juche. To study the Korean writers who choose North Korea after emancipation is very important in the process of literary unification. It is very important for scholar to free from cold war consciousness.

김재용,권민도,장호근,우종식,박주성,Kim, Jae-Yong,Kwon, Min-Do,Jang, Ho-Keun,Woo, Jong-Sik,Park, Ju-Sung 한국음향학회 1997 韓國音響學會誌 Vol.16 No.3

본 논문에서는 가야금 음의 분석결과를 바탕으로 가야금 음의 합성에 적합한 3 오퍼레이터 FM 합성방식을 고안하였다. 고안된 알고리즘에 사용될 파라메터를 MATLAB을 이용하여 추출하여 C언어를 이용하여 음을 합성하였다. 합성된 음을 주관적인 방법과 객관적인 방법으로 비교한 결과 두 음이 아주 흡사함을 확인했다. 제안된 합성방식을 DSP를 이용하여 구현하여 만든 합성음도 원음과 비슷한 음질을 가지는 것을 확인했다. In this paper, the 3 operator FM synthesis method has been devised on the basis of the analysis of Gayageum sounds. The parameters for the proposed synthesis algorithm has been implemented by C language. It is subjectively and objectively confirmed that the sounds synthesized by C language are very similar to the original sounds. The synthesis algorithm is also implemented by DSP, and the sounds from this experiment are close to the original ones.

Gas Adsorption Studies of Ar Molecules on a High-Energy-Beam Irradiated MgO Surface

김재용,Euikwon Kim,이정길,이윤만,Jaekyun Jeon,이상화,신혜민 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.5

Gas adsorption studies are useful to investigate the ne structure of a surface on an atomic scale. A meso-sized MgO (100) powder surface prepared by using the RF-induction method was irradiated by using an electron beam with energy of 2 MeV. The amount of electron beam dosage was varied from 20 kGy to 1000 kGy. By measuring the Ar gas adsorption data recorded below the triple point (83.78 K), we analyzed the surface changes in the MgO powder before and after the electron beam irradiation. X-ray and TEM investigations revealed that the surface structure was not affected by the irradiation with an electron beam. Calculated values of the 2-dimensional compressibility and the isosteric heat of adsorption coherently showed that a stronger interaction of Ar molecules existed for the electron-irradiated MgO powders than for the pure samples. These results imply the possibility of local surface modification due to bombardments with external electrons.

김재용,김영철,이장훈,우홍정,Kim, Jae-Yong,Kim, Young-Chul,Lee, Jang-Hoon,Woo, Hong-Jung 대한한방내과학회 2006 大韓韓方內科學會誌 Vol.27 No.1

Objectives: This study was done to evaluate the effects of Saengkankunbi-tang on cell-viability, proliferation, cell-cycle, apoptosis and DNA replication on HepG2 cell and to find out by which molecular-biological mechanism by which Saengkankunbi-tang operates. Methods : The MTT assay, cell counting assay, [3H]-thymidine incorporation assay, flow cytometric analysis, tryphan blue exclusion assay, western blot analysis, quantative RT-PCR were taken. Results : Saengkankunbi-tang had no effect on proliferation, cell-cycle and DNA replications of HepG2 cells, while it improved cell viability and reduced apoptosis, and it activated Akt and NFKB. But, it did not produce an effect on cell viability and apoptosis when P13K/Akt pathway was blocked by LY294002 nor when $NF{\kapa}B$ activation was blocked by DN-$I{\kapa}B$. Conclusion : These results suggests that Saengkankunbi-tang improves cell viability and reduces apoptosis of HepG2 cells, by activating $NF{\kapa}B$ through PI3K/Akt pathway.

Objective : Stroke is leading cause of death and more importantly it is cause of serious disability. The effective treatment of acute ischemic stroke still remains a challenge to modern medicine. Recent clinical trials have shown that carotid endareterctomy(CEA) provide overwhelming benefits compared with medical therapy in preventing subsequent stroke for symptomatic carotid stenosis. For the asymptomatic ones, the data are less compelling, but highly suggestive that CEA do have benefits in properly selected patients. Materials and Methods : To investigate the clinical manifestations of carotid stenosis and results of CEAs, authors analyzed retrospectively 19 CEAs in 16 patients from June 1986 to June 1999. Age of patients ranged from 55 to 76 years(median, 66) and male to female ratio was 14 to 2. The duration of follow-up was 1 to 144 months (median, 26). All of CEAs were done on the side of stenosis more than 80% and bilateral CEAs were done in three. Six CEAs were performed in asymptomatic patients. Results : Seventeen of 19 CEAs showed excellent results and complication rate was low although ipsilateral ischemic stroke occurred in two. Conclusion : CEA may be a valuable surgical treatment for ischemic stroke caused by carotid stenosis and also for prevention of stroke of asymptomatic patients with carotid stenosis.

The objective of this study was to compare the shear bonding strength of zirconia after cleaning the crown contaminated by saliva or blood and determine the effect of thermocycling. 180 specimens were embedded in acrylic resin. 20 Specimens in the positive control group were bonded with resin cement without contamination. 20 Specimens in the negative control group were washed with water for 20 seconds and then dried for 10 seconds. 120 Specimens contaminated by saliva or blood were cleaned by using three cleaning methods: 37% phosphoric acid gel, commercial cleanse, and 2.5% NaOCl. All samples were bonded with resin cement and divided into two subgroups: One was not aged, and the other was tested with 30,000 thermocycling. In both groups contamination by saliva and blood, no statistically significant difference was not found in control, groups cleansed by commercial cleanser and 2.5% NaOCl. When the groups cleansed with water and 37% phosphate gel were compared with the control, significantly low shear bond strength was shown. Thermocycling group showed statistically significantly low shear bond stress compared to the groups without thermocycling. When zirconia was contaminated by saliva or blood, its original shear bond strength could be obtained if it was cleaned with commercial cleanser or 2.5% NaOCl. 본 연구의 목적은 타액이나 혈액에 오염된 유치 지르코니아 기성관의 내면을 다양한 세척 방법으로 세척 한 뒤, 레진 시멘트와의 결합력을 비교하고, 열 순환이 결합력에 미치는 효과를 평가하였다. 지르코니아 기성관의 내면과 유사한 상태의 지르코니아 절편($5mm{\times}3mm$)을 아크릴릭 레진에 매몰하였다(n=180). 이 중 160개의 시편을 무작위로 두 군으로 나누어 타액 오염과 혈액 오염을 시행하였다. 양성 대조군은 오염 과정을 거치지 않고 resin cement로 접착을 시행하였고, 음성 대조군은 오염 후 dental unit chair 상의 물로 20초간 세척 후 10초간 건조를 시행하였다. 타액 오염된 시편과 (n=60) 혈액 오염된 시편(n=60)은 각각 세 가지 방법의 세척을 시행하였다. 37% 인산 젤, 상용 세척제(Ivoclean), 2.5% NaOCl을 각 시편에 20초간 적용 후 10초간 물로 세척하고 건조를 시행하였다. 이 후 모든 시편(n=160)에 접착을 시행하였다. 대조군과 각 실험군을 모두 절반으로 나누어 절반은 바로 전단응력을 측정하였고, 절반은 열 순환 과정 후 전단응력을 측정하였다. 타액오염과 혈액오염을 시행한 군 모두에서, 양성 대조군과 상용 세척제, 2.5% NaOCl으로 세척한 군에서 통계학적으로 유의한 차이는 존재하지 않았다. 음성 대조군과 37% 인산 젤로 세척한 군의 전단 결합 강도는 양성 대조군과 비교하였을 때, 유의하게 감소하였다. 열 순환 시행 시 타액 오염을 시행한 군과 혈액 오염을 시행한 모든 군에서 열 순환을 시행하지 않은 군보다 통계적으로 유의하게 낮은 전단 응력 간도를 나타내었다. 유치 지르코니아 기성관 내부의 타액 오염이나 혈액 오염 시, 상용 세척제나 2.5% NaOCl로 세척을 시행하면 원래의 전단응력 값을 얻을 수 있다. 열 순환 시행 시 모든 군에서 유의하게 낮은 전단 응력 값을 보였다.
