Objectives : To establish an effective collaborate medicine treatment of acupuncture and western medicine for treating frozen shoulder patients. Methods : 59 voluntary patients were randomly assigned to Eastern treatment group(E group, n=22), Western treatment group(W group, n=17) and East-West treatment group(EW group, n=20). The E group received acupuncture treatment on LI15, TE14, GB21 and Master Dong's acupuncture points, Shin-gwan and Gyun-joong, twice a week for 4 weeks. The W group received suprascapular nerve block, subacromial injection and trigger point injection, twice a week for 4 weeks. The EW group received acupuncture and injection treatment including nerve block. All groups were instructed to practice self exercise during their daily lives. Evaluations were made before treatment and after treatment based on the change in shoulder Range of Motion(ROM) and the patient's satisfaction concerning the treatment was measured by Visual Analogue Scale(VAS). The obtained data were analyzed and compared. Results : The patient's satisfaction scores were E group 5.67, W group 7.73 and EW group 7.67. The E group and the EW group showed significant improvement in abbduction, adduction and flexion(p<0.05). The W group showed significant improvement in adduction(p<0.05). Abduction significantly improved(p<0.05) in the EW group compared to E group and W group. Flexion also showed improvement in the EW group, but the difference among the 3 groups was statistically insignificant. The three group's difference of change in extension and adduction was insignificant(p>0.05). Conclusion : Acupuncture and nerve block alone significantly improved ROM in frozen shoulder patients. Also collaborate treatment of acupuncture and nerve block significantly improved ROM in frozen shoulder patients. But the difference of the three treatments were significant only for improving abduction(p<0.05).

솔껍질깍지벌레는 우리나라 곰솔림의 주요한 해충의 하나이다. 본 연구는 우리나라에서 솔껍질깍지벌레의 분포를 알아보기 위하여 7개도 3개 광역시, 91개 시군구, 686 읍면동의 해송림에서 2010년 밀도를 조사하였다. 5개도 2개 광역시에서 솔껍질깍지벌레가 서식하고 있었는데 시군구별로는 조사대상의 64.8%인 59개 시군구에서 서식이 확인되었다. 솔껍질깍지벌레의 분포는 남해안 전역과 동해안의 포항, 서해안의 충남 보령지역까지 분포하였다. 충북과 대전광역시 및 제주도에서는 솔껍질깍지벌레의 분포가 확인되지 않았다. 부산지역은 16곳의 모든 구에서 솔껍질깍지벌레가 분포하였고, 시군 단위에서는 전남 해남군의 솔껍질깍지벌레 평균밀도가 1.713마리/0.785 $cm^2$로 가장 높았으며 읍면동 단위에서는 해남군 송지면이 6.36마리/0.785 $cm^2$로 가장 높았다. 곰솔 가지 내의 솔껍질깍지벌레 밀도와 솔껍질깍지벌레가 서식하고 있는 빈도와는 높은 상관관계가 있었다(상관계수=0.89). The black pine bast scale, $Masucoccus$ $thunbergianae$ (Hemiptera: Margarodidae), is a serious pest of the Japanese black pine, $Pinus$ $thunbergii$, in Korea. The distribution of the black pine bast scale was examined, looking overall at 686 towns (eup), townships (myeon) or neighborhoods (dong). There were Japanese black pine ($Pinus$ $thunbergii$) forests in 91 cities, counties (gun) and borough (gu), in seven provinces and three metropolitan cities during 2010. Black pine bast scale were found in 64.8% of cities or counties or borough (59) in 7 provinces and 3 metropolitan cities, and were distributed in all South Costal regions, Pohang in East Costal region and Boryeong in West Costal region. Chungcheongbukdo, Daejeon and Jeju did not have black pine bast scale. All the gu regions in Busan had black pine bast scale, of which the area with the highest prevalence was Haenam in Jeollanamdo (1.713 crawlers/0.785 $cm^2$). Songji-myeon had the highest occurrence rate (6.36 crawlers/0.785 $cm^2$) from the towns, township and dong. The density of black pine bast scale in twigs was highly correlated with percentage of the sample with scale (Correlation coefficacy=0.89).

Strain type of lactic acid bacteria was analysed by PCR and SDS-PAGE. PCR allows the rapid and specific detection of lactic acid bacteria using primers based on 16S rRNA gene-sequences. The analysis of protein pattern on SDS-PAGE can be used to determine the differences among the same or similar species of lactic acid bacteria. Therefore, the complementary use of PCR and SDS-PAGE method is one of simple way to classify the lactic acid bacteria and to compare with genetic analysis.

Wind turbine system converts wind energy into electric energy. Since the velocity of wind is random in nature. control of the angular velocity of the blade is needed in order to generate high quality electric power. The control of a blade can be divided into a stall regulation type and a pitch control type. The stall regulation type which uses an aerodynamic stall is simple and cheap, but it suffers from fluctuation of the resulting power. On the contrary. pitch control type is based on the fact that the torque of the blade can be changed by varying the pitch angle of the blade. It is mechanically and mathematically complicated. but the control performance is better than that of the stall regulation type. This paper derives a mathematical modeling of the wind turbine system, and suggests a pitch control algorithm. The validity of the algorithm is demonstrated with the results produced through sets of simulation.

임성철,이용,김동출,강길,변익건,박정희,최석민 朝鮮大學校 附設 醫學硏究所 2004 The Medical Journal of Chosun University Vol.29 No.2

CD24 is a small heavily glycosylated glycosylphosphatidylinosito-linked cell surface protein, which is expressed in hematologic malignancies as well as in a large variety of solid tumors, It appears to function as a ligand of PUselectin, an adhesion molecule that is present in activated platelets and endothelial cells. The authors aimed to evaluate CD24 protein expression in adenoma and adenocarcinoma of gallbladder to correlate to clinicopathologic data. The staining- was evaluated as stainability (negative, weak-, moderate-, strong-positive) and staining' patterns (membranous vs. intracytoplasmic) for statistical analysis. A highly significant association of cytoplasmic CD24 expression with adenocarcinoma compared to the adenoma of gallbladder was demonstrated. The present study demonstrates that CD24 was abundantly expressed on adenocarcinoma rather than on adenoma, but it was not statistically significant, Interrelation between the stainability or intracytoplasmic staining of CD24 and lymph node metastasis was not statistically significant. The authors conclude that CD24 is involved in tumorigenesis of gallbladder mucosa and intracytoplasmic expression of CD24 is an important molecular marker for malignant transformation.

We have investigated Pt and RuO₂as a bottom electrode for a device application of PZT thin film. The bottom electrodes were prepared by using an RF magnetron sputtering method. We studied some of the property influencing factors such as substrate temperature, gas flow ratem and RF power. An oxygen partial pressure from 0 to 50% was investigated. The results show that only Ru metal was grown without supplying any ‬O₂gas. Both Ru and RuO₂phases were formed for ‬O₂partial pressure between 10-40%. A pure RuO₂phasewas obtained with ‬O₂partial pressure of 50%. A substrate temperature from room temperature to 400°C was investigated with XRD for the film crystallinity examination. The substrate temperature influenced the surface morphology and the resistivity of Pt and RuO₂ as well as the film crystal structure. From the various considerations, we recommend the substrate temperature of 300°C for the bottom electrode growth. Because PZT film growth on top of bottom electrode requires a temperature process higher than 500°C, bottom electrode properties were investigated as a functiona of post anneal temperature. As post anneal temperature was increasedm the resistibity of Pt and RuO₂was decreased. However, almost no change was observed in resistibity for an anneal temperature higher than 700°C . From the studies on resistivity and surface morphology, we recommend a post anneal temperature less than 600°C.

The finite element analysis was performed on the ULM's engine mount to verify the structural safety Result showed that proposed engine mount structure has a large margine of safety. Strains and stresses in the vicinity of the joint between a composite fuselage and a metallic engine mount were calculated by the finite element analysis program. Numerical results from the model were compared with the test results. Good agreement was found between experiment and model results.

Fe-Cr-Si과 Fe-Cr-Pt 합금의 고온 cyclic 산화거동에 관한 연구

임채선,조현준,최송천,이동복 成均館大學校 科學技術硏究所 1994 論文集 Vol.45 No.1

To investigate the cyclic oxidation behavior of Fe-Cr-Si and Fe-Cr-Pt alloys, both (82-94)wt% Fe-(5-15)wt% Cr--(1-3)wt% Si and (82-94)wt% Fe--(5-15)wt% Cr-(1--3) wt%Pt alloys were cyclically oxidized in air at 1000 and 1250℃. By the addition of Si or Pt, the oxidation resistance of Fe-Cr alloys was generally increased with the most pronouncing effects observed in Fe-15wt%Cr containing alloys. After oxidation, on the surface of Fe-Cr--Si alloys, complex oxide layers of Fe_20_3/Fe-Cr spinel/Si-rich oxide were formed, which provides the necessary oxidation resistance. Especially, Fe-15wt%Cr-3wt%Si alloys had best oxidation resistance because the inward diffusion of oxygen was considerably deterred owing to the formation of the protective inner Si0_2 layer from the initial oxidation stage. In Fe-Cr-Pt alloys, oxidation resistance was obtained by forming protective Cr_2 O_3 layers below initially formed outer Fe_2 0_3, layers. However, Fe-Cr-Pt alloys showed decreased oxidation resistance at 1250℃ compared with Fe-Cr-Si alloys.

유속과 곡관부의 형상 변화를 고려한 파이프 계의 자유진동 해석

A simulation is performed to study the change of the natural frequencies of curved pipe systems containing fluid flow, for different angles and geometry of the pipe systems. Based upon the Hamilton's principle, the equations of motions are derived. This paper consider an initially deformed state caused by the fluid flowing through the pipe at a constant velocity. This deformed state gives rise to initially tension force in the pipe. When the initial force is neglected in cured pipes, the natural frequencies are reduced as flow velocity increases. However, when the initial force is considered, the natural frequencies changed a little with the change of the flow velocity for changing shape(curvature, angle) of curved pipes. In free vibrational simulation of pipe systems, it is necessary to consider the initial force due to the flow velocity and the geometric shape of pipes. Like this, the initial force should be included in the equation of motion of the systems to get more accurate natural frequencies and the change of shape of curved pipes should be considered.
