This paper presents an architecture of high-performance JPEG CODEC circuit that can process one pixel per cycle. We reduced the circuit size by using a single transpose buffer and two-stage pipeline for DCT. Further reduction was achieved by sharing the buffers for VLC and VLD. Our circuit was verified using SoC platform board with Xilinx FPGA and ARM9 processor. The synthesized circuit has 48,738 gates and operates at a maximum frequency of 127㎒.

The root nodules of Elaeagnus umbellata were coralloid-shape due to repeated dichotomous branching of nodule meristem. The filamentous endophyte with vesicle cluster ranging from 30 ㎛ to 60 ㎛ in diameter was present only in the cortical cells. The isolated endophytes in vitro culture showed typical Frankia morphology, consisting of highly branched hyphae ranging from 0.8 ㎛ to 1.0 ㎛ in diameter, terminal and intraphyphal sporangia varing in shape and size up to 60 ㎛ in length and laminated vesicles. Its infectivity and effectivity were confirmed by induction of nitrogen-fixing root nodules on the inoculated seedlings of two Elaeagnus species. Consequently, the isolate was confirmed as a true symbiont of Elaeagnus umbellata root nodule and named Frankia EuIK1.

보리수나무(Elaeagnus umbellata) 뿌리혹엣 분리한 공생균주인 Frankia 균주 EuIK1 게놈에 대해 K. pneumoniae의 nifH,D를 탐침으로 Southern hybridization을 수행한 결과, 3.2 Kb와 5.5 Kb BamHI 절편과 15 Kb PstI 절편이 강한 혼성화 반응을 보여 이들 절편에 nifH,D 유전자가 존재함을 확인하였다. 동일 탐침을 사용한 colony hybridization을 통해 pWE15 cosmid vector 에 작성되 게놈 library로부터 하나의 nif-클론 (pEuNIF)을 선별하였다. 이 클론을 BamHI으로 절단한 후 동일한 탐침으로 혼성화 반응을 수행한 결과, 3.2 Kb와 5.5 Kb가 강한 혼성화 반응을 보였으며, 이 결과는 게놈 혼성화 반응 결과와 일치하였다. 그러나 Frankia FaC1의 nifH 만을 탐침으로 이용한 결과 3.2Kb BamHI 절편만이 혼성화 반응을 나타내었다. 또한 3.2 Kb의 3‘ 말단과 5.5 Kb의 5’ 말단의 염기서열로부터 추론한 아미노산 서열을 ArI3의 nifD와 비교한 결과 182번부터 240번까지, 241번부터 282번까지의 아미노산 서열과 각각 매우 높은 유사성을 보였다. 이러한 결과로부터 3.2Kb 절편에는 nifH와 일부의 nifD 서열이 존재하고, 이 절편에 연속된 5.5Kb 절편에는 나머지 nifD서열이 존재함을 알 수 있었다. Genomic Southern hybridization of Frankia EuIKl strain, a nitrogen fixing symbiont of Elaeagnus umbellate root nodules, with nifH,D of K. pneumoniae as a probe, showed that 3.2 Kb and 5.5 Kb of BamHI fragments and 15 Kb PstI fragment were strongly hybridized with the probe, indicating nifH,D are located on these fragments. Using the same probe, one clone(pEuNIF) was isolated from the genomic library constructed into pWE15 cosmid vector by colony hybridization. The 3.2 Kb and 5.5 Kb BamHI fragments of this clone were hybridized with the same probe and this result corresponds to the genomic Southern hybridization data. However, using nifH of Frankia FaCl strain as a probe, only the 3.2 Kb BamHI fragment showed hybridization signal. Amino acid sequence deduced from nucleotide sequence of 3' terminus of the 3.2 Kb and 5' terminus of the 5.5 Kb fragments showed that the former was highly homologous with that of ArI3 nifD from 182nd to 240th amino acids, while the latter was from 241st to 282nd amino acids. These results show that nifH and partial nifD sequences are located on the 3.2 Kb fragment and residual sequences of nifH on the 5.5 Kb fragment which is contiguous to the 3.2 Kb fragment.

Objectives: Hematuria can occur frequently for various reasons, but there are so many patients who suffered from unexplained hematuria. This study aims to report the clinical effect of Korean medicine on unexplained hematuria with chronic pelvic pain. Methods: The patient received Korean medicine therapies such as herbal medication, acupuncture, moxibustion, cupping therapy, and Korean medicine steam therapy (about 20 days). Results: Urine occult blood and urine micro red blood cell of the patient were noticeably reduced during the treatment. The clinical symptoms about chronic pelvic pain were also improved. Conclusions: This case shows that Korean medicine is effective on unexplained hematuria with chronic pelvic pain.

Objectives: The aim of this study is to analyze the utilization behaviour and influencing factors of complementary and alternative medicine (CAM) therapies among elderly people with chronic diseases. Methods: The study population was selected among 9 welfare facilities for the aged in 2 cities among Daegu Metropolitan City & Gyeongsangnam Province by two-stage cluster sampling. 250 senior citizens participated in a face-to-face interview using a structured questionnaire. Logistic regression analysis was performed to examine the association between the utilization of CAM therapies and various characteristics of the elderly. All statistics were analyzed using the PASW (ver 18.0). Results: Among 233 elderly peoples, 70.4% (164 persons) had used various kinds of CAM therapies (including nutritional methods, pharmacologic and biologic treatments, etc.) more than once during the last year. 48.8% (64 persons) ∼ 60.7% (88 persons) of the elderly used CAM therapies without health and medical experts" counsel. The elderly with perceptions of CAM therapy used it 2 times more than those without knowledge of CAM therapies. The number of chronic diseases was more likely to increase the usage of nutritional methods (OR=2.92, 95% CI: 1.07-7.97), manipulative and body-based practices (OR=5.85, 95% CI: 1.97-17.34), pharmacologic and biologic treatments (OR=2.92, 95% CI: 1.49-8.17). Elderly with diabetes used nutritional methods 3.76 (95% CI: 1.49-9.47) more than elderly without diabetes. Conclusions: CAM therapies use in the aged with chronic diseases appears common. The findings suggest that the clinical efficacy and safety of CAM therapies on medical management of chronic disease may be investigated and that patient-physician communication need to be strengthened.

They received Korean medicine therapies such as herbal medicine, moxibustion, and acupuncture. Results: After Korean medicine therapies, severity of symptoms of atropic vaginitis were reduced. Conclusions: The present study suggests that Korean medicine therapies have a effect on atrophic vaginitis in menopausal women.
