Purpose: This study has tried to find out the effects of music therapy on anxiety of surgery patients during operation under regional anesthesia. In order to find out the effects, this research design was used nonequivalent control group non-synchronized design. Method: The subjects were the sixty inpatients under regional anesthesia in K hospital. They were assigned to two groups, thirty to the experimental group and thirty to control group. The data were collected using the Visual Analogue Scale(VAS) for State Anxiety and vital sign. The Experimental group received favorite music of the 4 different genre. The control group were inserted ear plug during operation. Data were analyzed by $X^2$-test, T-test, ANOVA and Repeated Measured ANOVA of the SPSS WIN (12.0) version program. Results: 1) Hypothesis 1: The hypothesis "that the figure for state anxiety of the experimental group provided with music therapy would be lower than that of the control group" was confirmed(F=0.27, P=0.01). 2) Hypothesis 2 : Three subordinating hypotheses were established in order to verify the hypothesis "that the figures for vital sings of the experimental group provided with such as music therapy would be lower than those of the control group." were rejected. Conclusion: Music therapy can be regarded as an effective nursing intervention that relieves operative anxiety of surgical patients under regional anesthesia.

The present experiment was performed to investigate the acute and subacute effect of lead acetate on ultrastructural and biochemical changes in mouse diencephalon. In acute case, mouse were peritoneally injected with lead acetate at a dose of 0.26 mmole/kg body weight, and after treatment, mouse were sacrificed at time intervals of 12, 24, 48, and 96 hours. In subacute case, mouse were injected at doses of 0.07 mmoie/kg B. W. and 0.13 mmole/kg B.W. once at two days, and after treatment, mouse wee sacrificed at 1 week, 2 weeks, and 3 weeks. It was observed that after acute treatment, changes composed of increased monoamine oxidase activity, $Na^{+}-K^{+}$ ATPase activity, decreased $Mg^{2+}$-APTase activity, wrinkled myelin, swollen Golgi apparatus and more dense synaptic vesicle in nerve terminal. After subacute treatment, decreased monoamine oxidase activity, increased $Mg^{2+}$-ATPase, $Na^{+}-K^{+}$ ATPase, lose of myelin, uneven mitochondrial distribution, synaptic vesicular density and edema, but at a higher dose the effect was more severe. Therefore, lead acetate caused abnormal change of diencephalon, and at a subacute, it appears metal accumulative toxicity.

The surface status of a workpiece determines its functionality, product quality, and manufacturing costs. Thus, several finishing technologies have been widely investigated and applied to improve surface characteristics. In this study, rotational electro-magnetic abrasive finishing (REMAF) was suggested as a non-contact finishing process to achieve high geometric precision. To verify the effects of the REMAF process on burr removal on the surface of Al6061, experiments were conducted using the Taguchi method. Based on the experimental results analyzed by the S/N ratio and ANOVA, the optimal conditions were defined as A₃B₂C₃D₃ that corresponded to 1,800 rpm of rotational speed, 1.5 kg of abrasive particle weight, 0.7 mm of abrasive diameter, and 15 min of working time. In addition, the particle weight was a key attribute for deburring, whereas the working time was less effective.

Ascites is the retention of body fluids in abdominal cavity, which is induced by salt increase, and disorders in such things as water retention and albumin synthesis. Ascites are especially common in cases of progressed liver cirrhosis and metastatic cancer. One patient was diagnosed with liver cirrhosis and Metastatic cancer at Rt. liver from Lt. ovarian tumor by abdominal CT. To measure the response to treatment of ascites, these clinical symptoms were observed: weight, abdominal circumference, and lab findings. Clinical symptoms and ascites were improved after oriental medical treatment. Abdominal circumference decreased. Results suggest oriental medical treatment was effective for this patient for this disease, but more extensive research is needed.

This study was conducted to develop an efficiency prediction program of a hydraulic secondary energy converter for calculating annual power generation of a Wavestar type wave power generator. Using the period and wave height obtained from the frequency domain analysis, the behavior of the floating body was obtained by assuming the sin function. The piston displacement and speed of the hydraulic cylinder were calculated considering the behavior of the floating body and the shape of the mechanism. The numerical simulation of the hydraulic system was performed by physically modeling the hydraulic cylinders, check valves, hydraulic motors, which are the main devices. In the future, this analysis program will be used to develop a program for estimating annual power generation of a moveable body type wave power generation device.

Purpose: The purpose of this study was to evaluate the effect of Sodium hyaluronate-Sodium carboxymethyl cellulose (HA-CMC) on tissue adhesion after tenorrhapy in tenotomized Achilles tendon of the Sprague-Dawley rat. Materials and Methods: Twenty-eight legs of 14 Sprague-Dawley rat were used in study. After tenotomy of the Achilles tendons, tenorrhaphies were performed. Simple tenorrhaphy without any other procedures were performed on the left Achilles tendons (control group), and additional HA-CMC injections were done prior to the tenorrhaphy on the right Achilles tendons (HA-CMC group). Gross and histological examinations were made to identify differences between the two groups, 1, 2, 6, 8, 10, 12 and 14 weeks respectively. Results: Distinct decrease in granulation tissues and adhesions were seen in the HA-CMC group during gross inspection at 6 and 8 week after the operation. On histological analysis of the HA-CMC group, although increased infiltrations of inflammation cells were observed during 1 week, less adhesion were seen at 6, 8 and 10 weeks after the operation. In HA-CMC group, superior healing processes were seen at 6, 8 and 10 weeks and less fibrotic changes, compared to control group, were seen at 2 and 6 weeks. Conclusion: Prevention of adjacent tissue adhesion was made possible through decrease in collagen deposition and fibrosis by injecting HA-CMC before tenorrhaphy of Achilles tendon. Also, histologically faster healing process of the collagen fibers within the Achilles tendon was observed.

This study was conducted to investigate the biological activity and hepatoprotective effect of DWP-04 [DDB : selenium yeast: glutathione (31.1 : 6.8 : 62.1(w/w/w)] in D-galactosamine (GaIN) intoxicated rats. The DWP-04 (50, 100 or 200 mg/kg) or its vehicle was orally administered everyday before the start of GaIN injection (400 mg/kg, ip) for two weeks and animal decapitated for 24 hrs after GaIN­injected. The activities of serum enzymes, markers of liver function, were increased in the GaIN group compared to normal group and significantly lowered in the DWP-04 pretreated group than in the GaIN group. Hepatic lipid peroxide level and activities of phase 1 enzymes were significantly higher than those of GaIN group compared to normal group and lower in the DWP-04 pretreated group than in the GaIN group, and phase II enzyme activities in liver were lower in the GaIN group than in the normal group and were increased in the DWP-04 pretreated group than in the GaIN group. Total hepatic glutathione content and glutathione biosynthesis enzymes were lower in the GaIN group than in the normal group and were increased in the DWP-04 pretreated group than in the GaIN group. Therefore, the current results indicated that DWP-04 administration alleviated the GaIN-induced adverse effect through enhancing the antioxidant enzyme activities. 간기능 보호 작용이 있는 것으로 알려진 DDB, selenium과 glutathione의 혼합제제인 DWP-04의 간보호 작용을 검토할 목적으로 DWP-04를 실험동물에 경구로 투여하고서 D-galactosamine으로 간독성을 유발하여 혈액의 변동 및 간 조직에서의 활성산소 생성계 및 해독계의 활성에 미치는 영향을 관찰한 결과 GaIN의 단독투여는 대조군에 비하여 혈중 간 기능 지표효소 및 간 조직에서의 지질과산화의 함량이 현저히 증가하였으나, DWP-04의 전처리로 현저히 감소되었다. CaIN의 단독 투여로 활성산소의 생성계인 phase 1계의 효소가 현저히 증가하던 것이 DWP-04의 처리로 억제되었으며 해독계인 phase II계의 효소는 GaIN의 투여로 대조군에 비하여 억제되던 것이 DWP-04의 전처리로 정상군에는 미치지 않으나 유의성 있게 증가되었다. 간 조직중 glutathine의 함량은 CaIN의 투여로 현저히 억제되었으며 DWP-04의 투여로 증가하였는데 이러한 결과는 DWP-04의 투여로 glutathione peroxidase의 활성보다는 $\gamma-glutamylcysteine$ synthetase의 활성을 조절한 결과로 생각된다. 이상의 결과를 종합하여 볼 때 DWP-04의 투여는 활성산소의 생성 및 해독계를 조절하므로서 GaIN으로 인한 간손상을 보호하는 효과가 있는 것으로 사료된다.

일부 금속 및 기계제품 제조업체 근로자들의 산업재해($1980{\sim}1981$)에 관한 조사

이정희,Lee, Jung-Hee 대한예방의학회 1982 예방의학회지 Vol.15 No.1

1980. 1. 1부터 1981. 12. 31까지 만 2년간 서울 영등포 지역의 12개 금속 및 기계제품 제조업체 근로자들의 산업재해의 특성을 조사하여 얻은 결과는 다음과 같다. 1. 재해 발생율은 근로자 1000명당 45.7이며 남자 54.0, 여자 17.5로 남자에서 약 3배 이상 많이 발생하고 규모가 클수록 발생율이 감소하는 경향을 보였다. 2. 재해자들의 연령별 발생율은 19세 미만이 83.5로 제일 높고 $40{\sim}49$세가 가장 낮았다. 3. 근속 연수별 발생 분포는 1년 이하인 자가 48.1%로 근속연수가 짧을수록 재해빈도는 높았다. 4, 작업 개시 후 시간적 변동에 따른 발생율은 작업 개시 후 3시간이 6.0, 7시간이 6.1로 두 정점을 이루었다. 5. 요일별 재해 발생율은 월요일이 8.4(18.3%)로 가장 높았고 일요일이 가장 낮았다. 6. 월별 재해 발생율은 7월에 5.4(11.8%)로 가장 높았고 다음이 3월로 4.8(10.5%)였다. 계절별 발생율은 봄철에 13(28.4%)로 가장 높았다. 7. 재해원인별 발생빈도는 기계에 의한 것이 37.5%로 가장 높고, 다음이 기구없이 취급, 낙하물, 충돌에 의한 것이 각각 17.2%, 14.2% 및 10.2%를 차지하였다. 8. 상해 부위별 발생빈도는 상지부(上肢部)가 58.8% 하지부(下肢部)가 25.5%로 상하지(上下肢)가 전체의 84.3%였으며 이중 수지(手指)가 40.3%로 빈도가 제일 높았으며 좌우별 분포는 우측이 10%정도 많았다. 9. 상해 종류별 발생빈도는 열창 및 좌창이 34.0%로 가장 높았고 다음이 골절 및 탈구로 31.9%, 염좌 8.1%의 순이었다. 10. 요양 기간별 발생 분포는 2주에서 1개월이 54.4%로 가장 높았고 1개월 미만이 전체의 68.9%로 대부분이었으며 업체 규모가 클수록 치료기간이 연장되는 경향을 보였다. 11. 산재분 재해 대 비산재분 재해의 비율은 1:4.7이었다.리양상(解離樣相)은 거의 비슷하게 완만(緩慢)하였다. 4. 이상(以上)의 소견(所見)으로 미루어 볼 때 임신부(姙娠婦)의 CO 중독(中毒)은 산모(産母)보다 태아(胎兒)에서 더 큰 위해(危害)를 초래(招來)할 가능성(可能性)이 크며 또 HbF의 구성점유율(構成占有率)이 높은 6개월(個月) 이하(以下)의 영아에서도 그 위해도(危害度)가 클 것으로 간주(看做)된다. 따라서 임신부(姙娠婦) 또는 생후(生後) 6개월(個月) 이하(以下)의 영아가 CO 중독(中毒)되었을 때는 고압산소요법(高壓酸素療法)이 효과적(效果的)인 치료법(治療法)으로 보이며 그 치료시간(治療時間)을 성인환자(成人患者)에 있어서의 그것보다 좀 더 길게하는 것이 CO 중독(中毒)에 의한 위해(危害)를 감소(減少)시켜 줄 것으로 기대(期待) 된다. 있었다. 또한 공정 중 microwave와 autoclaving은 4가지 수산식품 낙지, 조기, 홍어, 새우의 allergenicity를 현저히 감소시키는 것으로 나타났다. 반면에 자외선은 단백질로 구성된 allergen의 구조는 크게 변화시키지 못하는 것으로 보여진 것을 알 수 있다. 그러므로 생선의 가공방법은 통조림 가공이나 microwave 처리가 allergenicity성을 감소시킬 수 있는 것으로 보여진다. 낙지, 조기, 홍어, 새우의 한외여과 fraction중 고분자인 100,000이상에서만 allergenicity가 나타났다. 따라서 이 allergen들의 분자량은 100,000 이상으로 추정되며 검색된 allergynicity 생선을 10,000∼100,000으로 한외여과 하였을 때 100,000 이상의 fraction에서만 PCA에 의해 allergenicity가 있는 것으로 인정되었다. 그러나 이 검색된 생선이 anaphylaxis가 인간에게서까지도 반응할지는 의문이다. 이 연구의 결과는 차후 임상실험환자에 의하여 최종 검증되어야 한다.일정한 관련성을 나타내지 The followings are the results of the study on industrial accidents occurred at 12 factories manufacturing metal products during the period of 2 years from January 1980 to December 1981 in the area of Yong-Dung-Po in Seoul.

Environment as an Indicator in the Buddhist Art of Asia

이정희,Lee, Jung-Hee 한국조형예술학회 2008 조형예술학연구 Vol.13 No.1

불교와 불교미술은 인도에서 발원하였지만, 그것들은 각 나라에 전파되면서 국제적인 환경을 만들어 냈다. 불교는 각 나라에 일종의 꾸러미의 형식으로 전파되었다. 예를 들면 불경, 불상과 불화의 도상과 양식, 건축과 그 기법, 복잡한 의식, 승려나 여승이 기거하는 사찰에서 건축적 요소와 그 기법들이 함께 소개되었다 불교의 시작은 인도의 아쇼카 왕조시기(reign of King Asoka)로 거슬러 올라가지만, 이후 각 나라의 정치적, 지적, 예술적, 종교적, 사회적, 자연적 환경, 지리적, 지질적 환경에 맞게 전개됐다. 불교미술은 토착화하면서 그 지역민을 닮은 상이 만들어 졌고, 또 지역마다 독특한 특색을 나타내면서 발전하기 시작했다. 스투파(stupa)와 차이챠 홀(chaitya hall)은 수도원의 독특한 분위기를 만들어 내곤 중앙아시아의 대상인들은 인도의 문화가 중국에 전해지는데 공헌했을 뿐만 아니라, 그들이 지나던 교역루트의 자연환경 덕분에 화려한 색채의 벽화들이 제작되고 보존될 수 있었다. 불교와 불교 미술이 중국과 한국, 일본에 전해졌을 때, 불교는 국가 제도와 사회적 조직의 일부가 되었다. 정치적 목적에 의해 거대한 불상들이 산속의 동굴에 만들어 지기도 했다. 중국은 스투파를 사각형의 기둥으로 변형시켰고, 기와를 얹은 지붕 형식의 탑을 만들어 냈다. 한국은 불교미술을 중국에서 일본으로 전파시켰을 뿐만 아니라, 고유한 방식으로 그것을 변형시켰다. 석굴암의 깊은 명상에 잠긴 듯한 보살상들의 이미지가 그 좋은 예이다. 중국에서는 신유교 철학이 국-가의 공식적인 이념이 되면서 선종의 부흥하기도 했으며, 일본의 선승들은 신도들의 명상을 북돋기 위해 선종 형식의 정원을 만들어 냈다. 티벳의 밀교에서도 불교미술의 중요한 발전양상을 확인할 수 있다. 밀교의 미술은 예술적 환경 뿐만 아니라, 지적이고 종교적인 것에도 속한다. 한편 티벳의 신들이 그들의 배우자를 안고 있는 모습은 신과 신자들의 융합을 상징하기도 한다. 불교미술은 독창적인 환경을 만들어 냈고, 여라 나라에 전파되면서, 상당한 변화를 낳았다. Buddhism and Buddhist art originated in India, but when they were introduced to different countries, they created an international environment. Buddhism was introduced as cultural package, with written texts, visual images, rituals, and the organization of monasteries. Buddhist art originated in India during the reign of King Asoka and then was developed under the political, intellectual, artistic, religious, social and natural environments of the regions. The stupa and the chaitya halls create monastic environment. The natural environment of the trade routes and caravans in the Central Asian deserts preserved brilliant-colored murals and helped spread tram India to China. When Buddhism and Buddhist art were introduced to China, Korea, and Japan, Buddhism became a part of government institution and social organization. Gigantic statues were carved in caves in mountains for political purposes. The Chinese transformed the stupa into a square pillar and created pagodas with tiled roofs in tower forms. Koreans not only transmitted the Buddhist art from China to Japan, but it also changed it with originality in the iconography of the pensive bodhisattva images and in the architecture of Seoggulam. The official ideology of Neo Confucian philosophy brought the rise of Chan Buddhism. Zen monasteries in Japan created unique environments by establishing the Zen Buddhist garden. to prompt believers to meditate. An important development in Buddhist art is the Esoteric Buddhist art in China and Tibet. This category belongs to the intellectual, religious as well as artistic environments. The Tibetan deities with consorts in their embrace symbolize the union of the god and the devotees. Buddhist art created a unique environment that was spread out to many nations and changed greatly over time.
