Objectives: The purpose of this study is to analyze the changes in the indices of body muscle strength, the indices of muscle strength associated with physical balance, and index of the pain relief between the intervention group who performed the muscle strength exercise and control group who not performed the muscle strength exercise. The study period was from September 7, 2016 to May 12, 2017, and it was conducted after receiving Institutional Review Board approval. Methods: Among 40 participants who were recruited in this study, the final analysis subjects were a total of 39 people, excluding the one people who dropped out during the 2-week. For analysis, the changes were compared with baseline and after two weeks by comparing three types of body muscle strength indices, four types of physical balance indices, and one type of pain relief index. Finally, we analyzed whether there is a difference between the groups in the each changes. Results: In the body muscle strength index change analysis, the change of muscle mass relative to weight was not statistically significant, but the difference between the groups regard to change was statistically significant (p<0.05). The lower body strength and the bone mineral were statistically significant in both the intervention and control group, but the difference between the groups regard to change was not statistically significant. In the index of muscle strength associated with physical balance change analysis, the intervention group showed improvement much higher in the right arm, left arm, right leg, and left leg of muscle mass than the control group. Also, the muscle mass of the right arm and the left arm was statistically significant in the analysis of the difference between the groups regard to change (p<0.05). Analysis of changes in pain relief index showed that the intervention group showed significantly improvement higher than the control group, and the difference between the groups regard to change was statistically significant (p<0.05). Conclusions: In the elderly patients in the hospital where the fall prevention program was provided, it was concluded that the intervention group higher improved the muscle strength associated with physical balance and the pain relief compared with the control group.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Carotenoids 식이와 알코올이 혈액학적 성분과 간조직에 미치는 영향에 관한 연구

조만희,김연선,이상한,우기민,장예진,김창세 순천향의학연구소 1999 Journal of Soonchunhyang Medical Science Vol.5 No.2

Alcohol is well known agent which can damage the human tissues such as liver via stimulating lipid peroxidation and storage, denaturation of macromolecules, and inhibiting protein metabolism. On the other hand, carotenoids in addition to vitamins A, C, E and lipoic acid, play important roles in protecting these oxidative damages as well as preventing the production of free radicals. This study was carried out to elucidate the precise effects of alcohol administration into rats on the antioxidative functions of dietary carotenoids and isolated β-carotene, and to find out any parameters to uncover more detailed biochemical mechanisms of these agents. For these purposes, two different approaches were performed: 1) examination of the changes in hematological parameters (e.g., total proteins, A/G ratio, ALT/AST et. al) and statistical correlations among inter- and intragroups, 2) examination of the histopathological changes by an electron microscope. The results were analyzed and summarized as following; (1) Carrot diet for one week caused a slight increase in albumin. A/G ratio and AST levels, and a slight decrease in ALT, ALP, BUN and uric acid levels. Two-week alcohol administration following carrot diet increased total proteins, albumin A/G ratio and BUN levels. However, both groups were shown to have little significant changes in cholesterol concentrations. (2) Cheese diet for one week caused a significant increase in total proteins, albumin, AST, ALP, uric acid and total cholesterol levels, and a significant decrease in A/G ratio and glucose concentrations. However, two-week β-carotene diet following cheese intake increased total proteins albumin, A/G ratio, BUN and total cholesterol levels, whereas AST, ALT, ALP and uric acid levels were decreased. (3) Alcohol administration for one week caused an increase in AST activities and a decrease in total proteins, albumin, ALT, ALP and BUN levels. A successive β-carotene diet following alcohol administration increased total proteins, albumin, ALT, ALP and BUN levels, whereas decreased AST and uric acid levels. However, there were not significant changes in A/G ratio, glucose and total cholesterol levels in both groups. (4) β-carotene diet for one week caused a slight increase in albumin, glucose, AST and uric acid levels, and a slight decrease in ALP and BUN levels. Two-weeks alcohol administration following β-carotene diet increased albumin, glucose, BUN and total cholesterol levels, whereas decreased AST, ALT, ALP and uric acid levels. (5) Although the pathological investigation on the liver did not reveal significant changes, cheese diet group (CH-BC/1-CH) was shown to have some lipid deposits. Some results were unexpected and different from typical hematological changes shown by other researchers. Nonetheless, these results strongly suggest that the liver damage or hepatism caused by alcohol intake affects many kinds of biochemical metabolisms, which results in significant changes in many hematological parameters. In addition, dietary carotenoid and isolated β-carotene were shown to have protective roles against the biochemical changes by alcohol intake.

Ⅲ급 부정교합자의 양악 수술과 하악 편악 수술 시 연조직 변화에 관한 비교 연구

박영국,장인희,이영준 대한치과교정학회 2006 대한치과교정학회지 Vol.36 No.1

악교정 수술 시행 시 연조직 변화에 대한 대부분의 연구는 Ⅱ급 부정교합을 대상으로 하였다. 또한 수술 방법에 따른 연조직 변화에 대한 비교 연구가 부족하였다. 따라서 이 연구는 골격성 Ⅲ급 부정교합자에서 상악골 전진술과 하악골 후퇴술을 동시에 시행한 양악 수술과 하악골 편악 수술 시행 시, 경조직과 연조직 측모 및 연조직 두께의 변화를 관찰하고, 수술 전후 변화의 상관성을 산출하며, 경조직 변화에 수반하는 연조직 변화의 비율을 산출하여 교정-악교정 수술 복합 치료 계획 수립과 결과의 예측에 이용하고자 시행되었다. 경희대학교 치과병원 교정과에 내원하여 골격성 Ⅲ급 부정교합자로 진단받은 환자 52명을 대상으로 하여, Le Fort I osteotomy를 이용한 상악골 전방이동술과 시상분할골절단술을 이용한 하악골 후퇴술을 시행한 양악 수술군 26명과 하악골 후퇴술만을 시행한 편악 수술군 26명으로 구분하여, 수술 전후 측모두부방사선규격사진을 계측, 분석하여 다음과 같은 결과를 얻었다. 양악 수술군은 골격 변화량의 72.4% 비율로 상순 부위 연조직의 전방 이동을 보였으며, 편악 수술군은 통계적으로 유의한 변화를 보이지 않았다. 비순각은 양악 수술군에서 편약 수술군에 비해 더 크게 증가하였다. 이순각은 편악수술군에서 더 크게 감소하였다. 하악골의 후방 이동에 따른 연조직 pogonion의 후방 이동은 양악 수술군에서 98%, 편악 수술군에서 109%로 편악 수술군에서 더 크게 나타났다. 양악 수술군에서는 편악 수술군에 비하여 경조직의 변화에 수반하는 상순에서의 큰 변화가 나타났다. 편악 수술군에서는 상순의 변화는 미약하엿으며, 하순 및 이부의 변화가 양악 수술군에 비해 두드러지게 나타났다. Numbers of postulations lie on the difference of integumental changes with two major surgical remedies of one jaw vs. two jaw surgery in skeletal Class Ⅲ malocclusion. Accordingly it was the aim of the study to elucidate the skeletal profile changes with an accompanying disposition of soft tissues, consequently to yield the correlation and ratio of soft tissue changes with two types of surgical procedures, which in turn make it possible to predict the soft tissue outcomes by means of assembled regression equations. Cephalometric headfilms of fifry two adult skeletal Class Ⅲ comprised of 26 maxillary advancement by Le Fort I osteotomy and mandibular setback by sagittal split ramus osteotomy simultaneously (double jaw surgery, group A), 26 mandibular setback alone (one jaw surgery, group B) were statistically analyzed. Group A manifested 72.4% soft tissue advancement to skeletal changes in the upper lip area, while group B appeared to have no statistically significant changes. The nasolabial angle showed more increment in group A than in group B, whereas the mentolabial angle illustrated more reduction in group B. The backward movement of soft tissue pogonion to skeletal change revealed 98% in group A, and 109% in group B. The double jaw surgery group characteristically revealed remarkable integ umental change in the upper lip area, while the one jaw surgery had major effects in the lower lip and soft tissue pogonion areas.

이상진(Sang-Jin Lee),권이영(Yi-Young Kwon),조성원(Sung-Won Cho),권희숙(Hee-Suk Kwon),신우창(Woo-Chang Shin) 한국식품영양과학회 2013 한국식품영양과학회지 Vol.42 No.4

본 연구에서는 한방이화주의 피부 생리기능 활성을 알아보기 위해 70% EtOH 추출물의 피부 미백, 주름 개선 및 항염증 효과를 조사하였다. HEE은 tyrosinase 활성 억제 및 tyrosine을 기질로 melanin이 형성되는 pathway에 관여하는 주요한 인자인 TRP-1과 TRP-2를 저해하는 작용 기전을 통해 피부 색소침착의 주요 원인 물질인 melanin 생합성을 농도 의존적으로 저해하는 것을 확인하였다. HEE은 피부진피 내 피부 탄력을 유지하는 elastin을 분해하는 효소인 elastase의 활성을 저해하였고, 피부의 keratinocyte가 생성분비하는 MMP-2와 MMP-9의 단백질 발현과 proteolytic 활성을 억제하여 노화에 따른 피부 주름 생성 억제할 수 있는 가능성을 확인하였다. 또한 세포 독성 없이 LPS에 의해 유도된 염증 반응을 50% 저해하는 HEE의 농도(IC50)는 24.9 μg/mL이며, 50 μg/mL 농도로 처리하였을 때 염증 반응 저해 효과가 70%로 높은 효과를 가지는 것을 확인하였다. 이상의 결과를 종합하면 HEE의 피부 미백, 주름 개선 및 항염증에 우수한 효과를 나타내고 있으므로 기능성 화장품의 주요한 소재로 이용 가치가 높을 것으로 사료된다. Extrinsic skin aging is characterized by the loss of skin tone and resilience, irregular pigmentation, and deep wrinkles. The aim of this study was to investigate the effects of Ehwa Makgeolli containing oriental herbs (Glycyrrhiza uralensis Fisch., Lycium chinense MILL., Morus alba L., and Saururus chinensis Baill) on skin whitening and wrinkling in human skin cells. We prepared Makgeolli extracts (HEE) with 70% ethanol. HEE significantly inhibited in vitro mushroom tyrosinase activity and reduced the cellular and secreted melanin content of mouse melanoma melanocytes (B16F1 cells). HEE down-regulated the protein expression of tyrosinase related protein (TRP)-1/-2, a key player in melanogenesis. Treatment with HEE in human keratinoctyes (HaCaT cells) inhibited the proteolytic activities of matrix metalloproteinase (MMP)-2/-9 in a dose-dependent manner and dramatically reduced the expression of MMP-2/-9. In addition, HEE attenuated lipopolysaccharide (LPS)- induced nitric oxide production in murine macrophages (RAW264.7 cells). These results indicate that HEE may be a great cosmeceutical ingredient for its whitening, anti-wrinkle, and anti-inflammatory effects.

Impact of E-Commerce on Allocation of Tax Revenue between Developed and Developing Countries

( Chang Hee Lee ) 서울대학교 아시아태평양법연구소 2005 Journal of Korean Law Vol.4 No.1

The advent of digital technology increases productivity, and will, as a whole, make the world better off. Nevertheless, advanced countries have suggested an increase of their share in inter-jurisdictional allocation of revenue, justifying their position with the rhetoric of tax neutrality and residence jurisdiction. Indeed these suggestions can be hardly justified in that the economic and legal assumptions underpinning the existing norm of inter-jurisdictional revenue allocation are not valid in a digital era. Tax neutrality will rather justify a new order that would assign more revenue to the developing countries. Maintaining the existing international tax order and fixing it in a make-shift way will not lead to this new order of international taxation, however, because digital technology enables a taxpayer to circumvent any such attempt. Creating an entirely new norm and imposing it on developed countries appears to be beyond the reach of developing countries, judging from the past experiences of bargaining between developed and developing countries, which may have no other choice but to acquiesce to these changes. Despite this pessimism, the United Nations may consider revising the UN Model to the interest of developing countries, because the very role of the UN Model is to provide bargaining leverage for a developing country in negotiating a real world treaty. Proposed changes to the UN Model are as follows: 1. Add a paragraph to article 7 (business profits) that permits a host country to impose withholding tax to all payments to a non-resident e-supplier in general, or upon the host country’s election, to a payment to an e-supplier from a domestic business that can deduct the payment. 2. Change article 7(4) to permit a host country to adopt a formula apportionment if an esupplier has a permanent establishment in the host country or if sales by a non-resident esupplier exceeds a certain sum of money. The impact of the Internet and digital technology has been one of the favorite topics of international taxation for the past several years. It has been made clear that the existing norm of international taxation is seriously affected by the advent of electronic commerce and digital technology. Because the issue involves state-of-theart technological innovation, suggestions for changing the international tax order have largely been proffered by the advanced countries and the international organizations consisting of or controlled by the same economically and technologically advanced countries. In essence these countries argue for lassiez-faire - that the existing norms, designed in the pre-digital era, should remain intact to the broadest extent possible. This paper addresses the impact of the Internet and digital technology on the allocation of tax revenue among nations, in particular between developed and developing countries. The thesis of the paper is three-fold: i) digital technology completely destroys the economic and legal basis for the existing rules of international taxation, implying the necessity of a complete overhaul, ii) extending the existing rules into the digital era, as suggested by developed countries, will increase the revenue share of developed countries at the loss of developing countries, and iii) despite this foreseeable outcome, developing countries do not have much choice but to suffer. In terms of a practical policy implication, this paper points out that make-shift suggestions within the boundary of the existing norms will not help developing countries. The right solution, from the perspective of a developing country, will be to impose taxes even without a permanent establishment and adopt formula apportionment, although changing tax treaties to this end appears to be beyond the reach of developing countries. The thesis is shown in five parts. Part I is a very short summary of the suggestions advanced thus far by developed countries for maintaining and applying the existing rules. Part II addresses the first thesis and analyzes the economic bases or assumptions underlying the existing rules or compromises of international revenue allocation, and it will show that digital technology breaks these assumptions. Part III briefly summarizes the second thesis, which is more or less known to the world, that the maintenance or application of the existing rules to the digital environment will reallocate revenue from developing to developed countries. Part IV shows that the policy suggestions proffered thus far by the OECD and the European Union are misdirected anachronisms. Part V proceeds to the third thesis, and will present a grim prediction that developing countries do not have much choice but to acquiesce to the advanced countries’ self-serving suggestions. This article does not discuss the tax administration issues raised by e-commerce, or more generally by the technological progress that facilitates the cross-border movement of goods, services and capital. As discussed in many studies,1) the administration issues are more complex and subtle and may indeed be more important than the substantive law issues. For example, where capital can instantly flow over the globe at a negligible transaction cost, even developed nations may have to enter into a tax competition to attract capital. At the level of substantive law,however, this development does not affect the residence jurisdiction of capital exporting countries, which reaches the capital income derived by its residents regardless of where it is invested. One may easily point to the tax deferral for the earnings retained in a foreign subsidiary, but a capital exporting country can unilaterally address the problem by anti-abuse measures such as the U.S. subpart F rules. Enforcing such a measure is hard work. The administrative difficulty of keeping track of the capital flow could be devastating. Addressing these administrative issues, however, is simply beyond the scope of this article.

이상한,조만희,신경현,김창세 순천향대학교 1989 논문집 Vol.12 No.3

This study was carried out to investigate the effects on the changes of the r-glutamyl transpeptidase activity of ethanol-administered white rats. There was classified into group; ethanol treated group(group A), ethanol treated group which was pretreated with ginseng extract(group B), ginseng extract treated group(group C), and ginseng extract treated group which was pretreated with ethanol(group D). White rats of four groups were treated with combined 1% ginseng extract and / or 20% ethanol for 30 days, and were measured the changes of r-GTP activity on the serum, hepatic and renal tissue sample collected at 5 days interval. Following results have been obtained. 1. The changes of serum r-GTP activity were significantly decreased in ethanol treated group B which was pretreated with ginseng extract than in ethanol treated group A. The values were highly significant at the 20th day of feeding. 2. The changes of hepatic r-GTP activity were more increased in group A and decreased in group D. The values were found significantly lowest in 10th and highest in 5th days. 3. The changes of renal r-GTP activity were more increased in group A and decreased in group D. The values were significantly highest in 10th and lowest in 20th days. Based on these results it was found that the changes of r-GTP activity between serum and hepato-renal tissue were exist and the protective action of ginseng against alcohol degradative effects was noted.
