Objective: Yang Geouk San Hwa - Tang (YGSHT) has been widely used in Sasang Constitutional Medicine of Korea for treatment of acute inflammatory symptom, such as palatine tonsillitis, polydipsia, headache, papule, pimple however, the mechanism of its anti-inflammatory activity has not been clarified. In this study, therefore, we investigated the mechanism of the inhibitory effect of YGSHT on LPS-induced inflammation. Materials and methods: The effect of YGSHT was analyzed by ELISA, RT-PCR and Western blotting in LPS-stimulated RAW264.7 cells. Results: We found that YGSHT suppressed not only the production of pre-inflammatory cytokines (IL-$1{\beta}$ and TNF-$\alpha$), the generation of nitric oxide (NO) and prostaglandin E (PGE)2, but also the mRNA expression of pre-inflammatory cytokines, inducible nitric oxide synthase (iNOS), and cyclooxygenase (COX)-2. Furthermore, YGSHT was shown to inhibit the phosphorylation of ERK1/2 and JNK1/2 and the activation and translocation of NF-kB from cytosol to nuclear in LPS-stimulated RAW264.7 cells. Conclusions: These results suggest that YGSHT exerts an anti-inflammatory effect through the regulation of the ERK1/2 and JNK1/2 pathway and NF-kB pathway, thereby decreasing production of pre-inflammatory cytokines, NO, and PGE2.

As information processing recently increases over Internet. there have been many researches about designing an efficient storage system to process a huge amount of information, which is based upon DTD in XML However, most of them have some difficulties in meaningful and structural presentation of XML documents and some restrictions in integration of many heterogeneous documents. In other word, we need a storage system which well-defines the structure of heterogeneous XML documents and integrates them. In this paper, we proposed a technique of an XML documentation storage system using DTD integration graphs based on CSB+-tree. This technique retrieves structural information from elements of XML documents, creates a CSB+-tree based DTD integrated graphs of the man storage system, and generates an integrated storage system by using element mappings. The proposed technique utilizes the man storage system more efficiently in space and provides more faster response time.

The monthly mean daily global solar radiation and sunshine duration, have been employed in this study to develop correlation model for Daegwallyeong during 2011. The corresponding monthly value of extraterrestrial solar radiation and possible duration of sunshine are calculated for Daegwallyeong meteorological data. Forecasting performance parameters such as coefficient of determination (R2), mean bias error (MBE) and root mean square error (RMSE) are presented as analyzed for the model. The model with multi-linear regression has the highest R2 value of 0.95 and average MBE and RMSE values of −0.11 MJ/m2day and 1.63 MJ/m2day, respectively. The model exhibited negative MBE which shows that the model resulted in underestimation of the global solar radiation relative to the meteorological measured value. The equation could be employed in the estimation of solar radiation at Daegwallyeong, other locations with similar meteorological characteristics.

목적 : 다제내성 폐렴구균에 의한 수막염은 기존과 단일 항생제로는 근치가 어려워 ceftriaxone과 vancomycin 혹은 rifampin의 병용요법이 권유되고 있다. 다제내성 폐렴구균에 사용할 수 있는 다른 약제 중 meropenem은 시험관내 폐렴구균에 대한 항균력이 좋고 경련 등의 중추신경계 부작용이 거의 없어 다제내성 폐렴구균에 의한 수막염의 치료에 이용할 수 있을 것으로 기대되나 이에 대한 자료가 매우 부족한 상태이다. 이에 연자 등은 meropenem과 meropenem+vancomycin의 병용요법이 다제내성 폐렴구균 수막염의 치료에 효과가 있는지를 토끼 수막염 동물 모델을 이용하여 검증하고자 하였다. 방법 : 인체에서 수막염을 일으킨 다제내성 폐렴구균 균주(penicillin MIC 2, ceftriaxone MIC 4, meropenem MIC 0.5㎍/㎖)를 토끼 척수강 내에 직접 주입하여 수막염을 유발한 후 ceftriaxone, vancomycin, rifampin, meropenem의 단일 항균요법, ceftriaxone+vancomycin, ceftriaxone+rifampin, meropenem+vancomycin의 병용요법 간에 치료 효과의 차이를 비교 하였다. 각 치료군은 6 마리의 토끼를 대상으로 하였다. 각각의 항생제는 5 시간 간격으로 2번 정주하였으며, ceftriaxone은 1회 투여하였다. 균주 주입 후 각 치료군이 토끼에서 치료 후 0, 5, 10, 24 시간에 척수액을 채취하여 균주의 수를 측정하여 24시간째의 살균 여부를 최종 치료 효과로 판정하였다. 결과 : meropenem 단독 요법은 10시간째에 모든 균주를 살균하였으나 24시간 째에 다시 균의 성장이 관찰되었으며, meropenem+vancomycin의 병용요법은 단독 약제보다 우수한 살균효과를 보였으나 상승작용은 없었다. 결론 : meropenem+vancomycin의 병용요법은 기존의 ceftriaxone+vancomycin보다 24시간째에 더 큰 균의 감소 경향을 보여(P=0.054) 임상에서 사용이 가능할 것으로 기대되며 향후 실제 수막염 환자에서의 임상효과를 증명하는 연구가 필요할 것으로 생각된다. Background : Because antimicrobial monotherapy for pneumococcal meningitis caused by penicillin-resistant strains is not satisfactory, ceftriaxone+vancomycin [C+V] or ceftriaxone+rifampin [C+R] regimens are recommended. Meropenern [M] is one of the monotherapy options for penicillin-resistant pneumococcal meningitis due to good in-vitro activity against pneumococci and rare adverse reactions in CNS. But there have been few reports in the efficacy of meropenern against pneumococcal meningitis. We evaluated therapeutic efficacy of the meropenern and meropenem+vancomycin in a rabbit model of meningitis caused by penicillin-resistant S. pneumoniae (PRSP). Methods : Meningitis was induced by intracistemal inoculation of a pneumococcal strain isolated from a patient with meningitis (MIC; penicillin 2, ceftriaxone 4, meropenem 0.5 g/㎖). Bacterial concentrations in the CSF were measured at 0, 5, 10, and 24 h after therapy was started. Therapeutic efficacy was evaluated by the final bacterial concentration in the CSF at 24 h. Results : C+V cleared the CSF at 10 h, but regrowth of bacteria was noted at 24 h. Meropenem monotherapy resulted in sterilization at 10 h but regrowth at 24 h. M+V was superior to M or V monotherapy but did not show synergism. Therapeutic efficacy of M+V was at least equal or superior to that of C+V (P = 0.054). Conclusion : Meropenem+vancomycin regimen could be one of the useful options in the treatment of PRSP meningitis. Clinical trials to evaluate the M or M +V are warranted in the future.

The purpose of this study was to investigate the effect of knee exercises on the onset times of vastus medialis oblique muscle (VMO) and vastus lateralis muscle (VL) and in healthy subjects. Fifteen subjects (7 men, 8 women) in a mean age of 25.4 years participated in the study. Electromyographic (EMG) signals were recorded from the VMO and VL under four exercises. Knee exercises consisted of open kinematic terminal knee extension, straight leg raising, isometric hip adduction exercise, and closed kinematic terminal knee extension. No significant differences were found in the onset times of EMG activities of VMO and VL in the four exercises. There were also no significant differences among the exercises. These results coincided with previous studies that found no difference between onset of VMO and VL. However, it is difficult to say that there is no difference between onset of VMO and VL in healthy subjects. To confirm this results, further researches that follow same onset determination metod and exercises are needed. Not only is the study of onset time of muscle needed, but also the studies of the amount of activation and the rate of increase of muscle activation are needed.

Methods of major transport system used in many industry fields are conveyor belt, magnetic levitation system and indexing system. It is an indispensable device in many fields and especially it is very important in the factory automation. However, the conventional transport system can damage precision optical components by the contact force and destroy the inner structure of semiconductor by the magnetic field. The new transport system for transporting without damage is required and the ultrasonic wave transport system has been proposed to replace the conventional transport system. In this paper. the object transport system using the ultrasonic wave is developed. Traveling waves are generated through the use of the ultrasonic wave generator to two ends of the beam. The modelling equation on steady state response of ultrasonic vibration is expressed through normal mode expansion. Natural frequency of flexural beam is estimated. Transport direction of the object is analyzed according to phase difference and frequency. In addition, it is verified by experiment.

Background: People with insulin resistance has a higher risk of developing cardiovascular disease. This leads to the importance in diagnosing metabolic syndrome. The incidence of metabolic syndrome has increased significantly in korea because of an increased population of obese people and also the incidence of DM. There have been many studies done on the incidence of metabolic syndrome in the general population. Therefore, the authors have designed this study to identify the incidence of metabolic syndrome in patients with type 2 DM and also the associated characteristics in that population. Methods: The study included 169 adults over the age of 20 (84 males and 85 females) admitted to the endocrinology department of Chosun University between Jan, 1st 2005 and May, 31st 2006. Out of the people diagnosed with type 2 DM people were excluded when any of the physical measurements (height, weight, blood pressure, abdominal circumference) and blood measurements (TG, HDL-cholesterol, fasting blood sugar) were insufficient and when the patient was taking any drugs other than anti-hy-pertensive agents and oral anti-diabetic agents. Obesity and the other risk factors were defined by the Asian-Pacific guideline and 2001 ATP III of NCEP, respectively. Result: The each prevalence according to the metabolic syndrome criteria of the type 2 DM patients showed low HDL cholesterolemia with the highest incidence of 57.4% followed by hypertng1yceridemia(52.0%), obesity(40.9%) and hypertension(33.0%). The each incidence of diagnostic criteria in metabolic syndrome according to sex was different, In males, hypertriglyceridemia was the highest with the incidence of 57.7% followed by low HDL-cho1estero1emia(49.5%), obesity(40.9%) and hypertension (30.0%). In women, the incidence were low HDL-cho1estero1emia(64.8%), hyperthg1yceridemia(47.6%), obesity(45.0%) and hypertension(36.0%), in a descending order. The analysis between the diagnosis of metabolic syndrome in type 2 DM patients and the criteria showed that hyperthglyceridemia (correlative value 0.575) had the highest correlation followed by low HDL-cholesterolemia (correlative value 0.446), obesity (correlative value 0.350) and hypertension (correlative value 0.410). All the correlations were statistically significant with a p-value less than 0.01. Conclusions: Type 2 DM is a important factor of metabolic syndrome based on insulin resistance. The control of blood glucose with prevention and early diagnosis of the other factors related to metabolic syndrome in type 2 DM is important for preventing cardiovascular complications.
