We have examined the purgative effect of three Jechun-jun formulas in sprague dawley(SD) rat. Three jechun-jun formulas were Jechun-jun(Sample I ) and augmented Jechun-jun(Sample II) and augmented Jechun-jun add rhubarb(sample III ). We examined the amount and the humidity of feces in rat. The experimental animals were devided into four groups. as control group and three Jechun-jun (sample I, II, III). We administerd the water extract of sample I, II, III to rat per oral for 8days long. After every 24hours measured the amount of wet feces from rats in metabolic cage. Humidity rate of feces from rat was at first measure wet feces for 24hours (W) and measure dried feces (W1) and then we consider W-W1 as humidity. High humidity rate means constipation changes into moistening stool. The amount of wet feces and humidity rate of feces in rats were increased in sample I, II, III. Sample I has highest humidity rate of feces. so showed strong moistening effect. Sample II has mild effect in treating constipation. sample III has most amount of wet feces. in conclusion Jechun-jun has an effect of moistening stool. and augmented Jechun-jun add rhubarb has strong purgative effect.

Jun, Young Bae,Song, Seok Zun,Kim, Seon Jeong,Hong, Sung Min 濟州大學校 基礎科學硏究所 1999 基礎科學硏究 Vol.12 No.1
We state the fuzzification of *-subalgebras, o-subalgebras, additive ideals and Varlet ideals, and investigate their properties. We give an equivalent condition for a fuzzy (implicative) idea. We show that, in a BCK -algebra with condition(S), the notion of fuzzy ideals and fuzzy additive ideals coincide, and that, in a positive implicative BCK -algebra with condition (S), the notion of fuzzy ideals, fuzzy Varlet ideals and fuzzy additive ideals coincide.

The BIBA (Busan Ion Beam Accelerator) is a compact linear accelerator facility using the 28 GHz ECRIS (Electron Cyclotron Resonance Ion Source) at the KBSI (Korea Basic Science Institute). The superconducting magnets of the 28 GHz ECRIS produce high magnetic fields for strong confinement of plasmas in an ion source chamber. For stable operation of the superconducting magnets, performance of cryostat system is very essential. However, the cryostat system produces significant quantities of the heating due to conduction from room temperature. In addition, part of the X-ray radiation produced by the collisions of the electrons within the ion source chamber is absorbed by the cold mass of the superconducting magnet, leading to an additional heat load in the cryostat system. In this paper, a study on the performance of the cryostat system for 28 GHz ECRIS is performed to improve the cooling efficiency of the cryostat system.

Purpose: Neoplastic progression is accompanied bymultiple genetic alterations, which include the functionalloss of tumor suppressor genes, and tumorspecific genetic alterations are increasingly being investigatedas molecular tumor markers. Recently,genetic changes including microsatellite alterationshave been found in the serum DNA of cancer patients.Many studies have shown that alterations in the DNAisolated from serum tend to be identical to thosefound in tumor tissue. If so, serum DNA alterationsmay be very useful for detecting tumoral geneticchanges. The aim of this study was to detect chromosome3p microsatellite alterations, such as loss ofheterozygosity (LOH) and m icrosatellite instability, inthe serum DNA of lung cancer patients.Methods: A total of 46 lung cancer patients wereenrolled in the study. After DNA extraction from bloodlymphocytes and the serum of lung cancer patientsusing a DNA extraction kit, microsatellite alterationswere detected by using different markers (D3S4623,D3S4597, D3S1573).Results: W e found that heterozygotes were presentin 18 of 46 cases (39%) for D3S4623, and LOH wasdetected in two of these 18 cases (11% ). In D3S4597,heterozygotes were present in 26 of 46 cases (56.5%)and LOH was detected in 9 of these 26 heterozygotes(34.6%). Heterozygotes of D3S1573 were present in 19of 46 cases (41.3%) and LOH was detected in 7 of these19 cases (36.8%). The serum DNA of 10 of 26 patientsexhibited LOH in at least one of the three markersinvestigated (38.46%).Conclusion: Our result suggest that the m icrosatellitealterations in tumor DNA can be detected in theserum of lung cancer patients, and that serum DNAmay be usefully used for the diagnosis and screeningof lung cancer.

A Capacitance Estimation of Film Capacitors in an LCL-Filter of Grid-Connected PWM Converters
Hong-Jun Heo,Won-Sang Im,Jang-Sik Kim,Jang-Mok Kim 전력전자학회 2013 JOURNAL OF POWER ELECTRONICS Vol.13 No.1
A capacitor deterioration of LCL-filter grid-connected PWM converters is progressed by the self-healing mechanism. It leads to the degradation of the filter performance and drop of power factor. Thus, it is required to diagnose fault-point of capacitors and determine the replacement time. Typically, the fault of capacitors is determined when the capacitance is reduced up to 80% from initial value. This paper proposes algorithm to the determine capacitor replacement time of an LCL filter. The algorithm takes the advantage of change of the response on the injected resonant frequency corresponding to 80% value from the initial capacitance. The results of the algorithm are demonstrated through simulations and experiments.

Objectives: The purpose of this in vivo study was to investigate the microbial diversity in symptomatic and asymptomatic canals with primary endodontic infections by using GS FLX Titanium pyrosequencing. Materials and Methods: Sequencing was performed on 6 teeth (symptomatic, n = 3; asymptomatic, n = 3) with primary endodontic infections. Amplicons from hypervariable region of the small-subunit ribosomal RNA gene were generated by polymerized chain reaction (PCR), and sequenced by means of the GS FLX Titanium pyrosequencing. Results: On average, 10,639 and 45,455 16S rRNA sequences for asymptomatic and symptomatic teeth were obtained, respectively. Based on Ribosomal Database Project Classifier analysis, pyrosequencing identified the 141 bacterial genera in 13 phyla. The vast majority of sequences belonged to one of the seven phyla: Actinobacteria, Bacteroidetes, Firmicutes, Fusobacteria, Proteobacteria, Spirochetes, and Synergistetes. In genus level, Pyramidobacter, Streptococcus, and Leptotrichia constituted about 50% of microbial profile in asymptomatic teeth, whereas Neisseria, Propionibacterium, and Tessaracoccus were frequently found in symptomatic teeth (69%). Grouping the sequences in operational taxonomic units (3%) yielded 450 and 1,997 species level phylotypes in asymptomatic and symptomatic teeth, respectively. The total bacteria counts were significantly higher in symptomatic teeth than that of asymptomatic teeth (p < 0.05). Conclusions: GS FLX Titanium pyrosequencing could reveal a previously unidentified high bacterial diversity in primary endodontic infections. 연구목적: 본 연구는 원발성 치근단 치주염(primary apical periodontitis)을 갖는 치아에서 임상증상 유무에 따른 미생물 군집의 차이를 GS FLX Titanium pyrosequencing을 이용하여 species level까지 분석하였다. 연구 재료 및 방법: 원발성 치근단 치주염을 갖는 6개의 표본에서 pysequencing을 시행하였다. 중합효소 연쇄반응(PCR)에 의해 얻어진 small-subunit ribosomal RNA의 초가변 영역(hypervariable region)의 amplicon을 이용하여 GS FLX Titanium pyrosequencing 을 시행하였다. 결과: 평균적으로 무증상군 및 증상군에서 각각 10,639 및 45,455개의 16S rRNA sequence을 얻었으며 평균길이는 440bases였다. Ribosomal Database Project Classifier을 이용한 분석결과 142종의 genera 및 13종의 phylum 수준에서 의 세균종을 검출하였다. 검출된 13개의 phyla 가운데 Actinobacteria, Bacteroidetes, Firmicutes, Fusobacteria, Proteobacteria, Spirochetes, and Synergistetes 종이 상대적으로 호발하였으며, genus 수준에서는 Pyramidobacter, Streptococcus, Leptotrichia이 무증상의 근관의 50%를 차지하였으며, Neisseria, Propionibacterium, Tessaracoccus 균종은 증상이 있는 근관의 69%를 차지하였다. Operational taxonomic units (3%)로 나눈 결과 증상이 없는 치아에서 450개, 증상이 있는 치아에서 1,997개의 species가 발견되었다. 증상이 있는 치아에서 통계적으로 유의성 있게 많은 수의 세균이 검출되었다(p < 0.05). 결론: GS FLX Titanium Pyrosequencing 기법을 통해 원발성 감염근관에서 이전에 검출하지 못했던 다양한 근관내 분포 세균을 검출할 수 있었다.
