Objectives : This study was performed to investigate the effect of invasive laser acupuncture treatment at Liver Brook (LR2) acupoint and Liver Sea (LR8) acupoint on liver damage induced by D-galactosamine (D-GalN) in rats Methods : Liver damage was induced by D-GalN. The experimental rats were divided into two groups (control group, Low Level Laser Treatment (LLLT) group). Control groups were classified into small groups. Intact group had no liver damage and no treatment. D-GalN group was induced liver damage induced by D-GalN and not treated. LLLT group were induced liver damage induced by D-GalN and then treated at the LR2 or LR8 acupoint with 532, 658, 904 nm invasive laser acupuncture. The treatment was carried out three days at a time for 15days at both acupoints. To examine mechanism of the effect of invasive laser acupuncture, we measured the contents of ASP, ALT, ALP, TBIL in serum, CBC in blood and SOD in liver tissue. Results : The change of body weight increased in all groups. That change was AST and ALP, the AST activity decreased significantly compared with the control groups and decreased by 532 nm and 904 nm both LLLT groups. But ALP increased at LR8 acupoint by 658 nm. TBIL level significantly decreased in all LLLT groups. The SOD of LLLT groups increased in the liver tissue of rats compared to the control groups. SOD activity indicated that LLLT can help cellular defense mechanism by preventing scavenging hydrogen peroxide. In the change of WBC, it was increased in D-GalN Control group compared to intact group and LLLT groups. Conclusions : These results suggested that invasive laser acupuncture treatment at LR2 or LR8 acupoint reduced activation of hepatic enzyme and damage of liver tissue. Thus, the effect of invasive laser acupuncture was nearly identical to the way of the traditional acupuncture for the treatment of hepatocytotoxicity.

Objective: This study was conducted to observe the anti-hyperlipidemic and anti-inflammatory effects, as well as the metabolic benefits, of pear extract and herbal drug mixture (Lycii Fructus, Coicis Semen, Alimatis Rhizoma, and Astragali Radix) on rats fed with a high fat diet. Methods : The animals used were male rats and the control group was fed a high fat diet only. The experimental groups were divided into four. ExpⅠ group was fed a high fat diet with a mixture of pear extract and 3% Lycii Fructus; Exp Ⅱ group was fed a high fat diet with a mixture of pear extract and 3% Coicis Semen; Exp Ⅲ group was ed a high fat diet with a mixture of pear extract and 3% Alimatis Rhizoma; and Exp Ⅳ group was fed a high fat diet with a mixture of pear extract and 3% Astragali Radix for 4 weeks. Results: The body weight gain increased in all groups, but attenuated gradually in the experimental groups compared to the control group. The food intakes were significantly lower in ExpⅠ and Exp Ⅲ groups than the control group. The concentrations of serum total cholesterol (TC), HDL-cholesterol, LDL-cholesterol, and triglyceride (TG) were significantly higher in Exp Ⅱ than in the control group, and lower in Exp Ⅲ group than in the control group. Also the concentration of serum free fatty acid was significantly lower in the Exp Ⅲ group than in the control group. In inflammatory activities, the Exp Ⅱ group was significantly lower than the control group. Conclusion: The results indicated that Exp Ⅲ group (administered a mixture of pear extract and Alimatis Rhizoma) most efficiently reduced fat accumulation and body weight, while the Exp Ⅱ group (administered the mixture of pear extract and Coicis Semen) had the highest elevated lipid metabolism and immune activity.

The study was carried out for lightning surge analysis to design of lightning protection and ins-ulation coordination examination for a model system. In computer simulation, electromagnetic transients program(EMTP) developed in Bonneville Power Administration(BPA) was used. Main resuslts obtained are as follows. (1) Design technique of earthing system under transients and algorithm for lightning surge analysis considering with the effects of frequency dependence are described. (2) Lightning arresters for protecting the apparatus in an 154kV Gas-insulated switchgear type su-bstation is possible to elminate in the case when the lightning current is less than 80KA. (3) Installing of arresters on main transformer sides Is more effective for suppressing overvoltage magnitudes that of arrester on substation entrance side. (4) Insulation level of the electrical equipments can be reduced by applying corona model, multi phase networks, frequency dependent effects of the transmission lines and reasonable arrangement of lightning arresters.

역설계

김왕도 대한기계학회 1993 大韓機械學會誌 Vol.33 No.4

역설계란 제품에서부터 역으로 그것의 수학적인 형상을 얻는 기법이다. 생산현장과 설계분야에서 역설계의 응용사례는 많다. 예를 들면 자동차 외형설계자는 자유곡면(free form)을 만들고, 이것 에서 역으로 스템핑 다이(stamping die)를 가공한다. 물론 외형 설계자는 자유곡면을 생성하기 위해 스틸이나 커크사이트(kirtsite)보다는 원하는 형상을 만들기 쉬운 진흙을 사용한다. 생산부 서에서는 가공물의 설계도가 분실되거나 훼손되어 완성된 제품에서 도면이 복사되어야 할 경우가 생기게 된다. 역설계는 복제가 요구되는 어떤 형상도 적용이 가능하다. 응용대상은 특히 완구, 인조팔, 스템핑다이, 폼 블록(from block), 욕조기, 가구, 일상용품 등이며 적용대상은 광범위하다. 역설계는 설계자가 습득해야 할 필요기술이고, 현재의 CAD/CAM 적용영역을 새로운 세계로 확대시킬 것이다.

본 연구의 목적은 여행상품 속성이 사회적기업의 여행상품에 대한 소비가치와 구매의도의 관계에 미치는 영향을 알아보는 것이다. 실증적 연구를 위해 2015년 3월부터 4월까지 부산에서 설문조사를 실시하였으며, 분석을 위해 406개의 표본을 사용하였다. 분석 결과, 감성적 가치, 인식적 가치와 같은 소비가치는 사회적기업의 여행상품 구매의도에 영향을 미치는 것으로 나타났다. 사회적 속성은 사회적기업의 여행상품에 대한 소비가치와 구매의도 사이의 관계에 조절효과가 있는 것으로 나타났다. 결과의 이론적, 실제적 함의를 향후 연구 방향과 함께 제시하였다. The aim of study was to examine the effect of attributes of travel products on the relationship between consumption value and purchase intention for travel products of social enterprise. For empirical study, the survey was conducted during the period from March to April 2015 in Busan and 406 samples were used for the analysis. According to the analysis, consumption value such as emotional value and epistemic value affected on purchase intention for travel products of social enterprise. The social attribute had a moderating effect on relationship between consumption value and purchase intention for travel products of social enterprise. Theoretical and practical implications of the results were addressed with the directions for future study.

The transient characteristics of grounding systems are very important in the insulation design of electrical installations and depend on the shape and size of electrodes, soil resistivity and the magnitude and wave of the injection current. This paper establishes an algorithm to compute the surge impedance of two or more grounding systems using the Laplace Transformation technique and deals with the analysis of the transient characteristics on grounding systems.
