This study aims to provide a basic understanding of some of the functional properties and antioxidative effect of water (PTW) and ethanol (PTE) extracts from Poncirus trifoliata immature fruits for the development of functional material. For the total flavonoid and polyphenol compound contents, PTW was 4.66 mg/g and 42.63 mg/g, while PTE was 15.79 mg/g and 21.85 mg/g, respectively. The PTW showed the highest superoxide dismutase (SOD)-like activity of 71.43% and PTE was 59.42% at 2.0 mg/mL. The electron donating abilities of PTW and PTE were over 90% at 1.0 mg/mL, representing an excellent activity compared to the ascorbic acid (88.89%). The nitrite scavenging ability of PTW was 95.23% at pH 1.2 and 78.59% at pH 3.0. As a result, PTW had higher values of polyphenol content, the electron donating ability and the nitrite scavenging ability than ascorbic acid. This results suggest that PTW is a potentially useful antioxidant source for the development of functional healthy product, medicine, and cosmetic products.

Objectives : Overactive bladder(OAB) is a symptom syndrome including urinary urgency with or without urinary incontinence, usually combined with frequency and nocturia. There are lots of reports concerning the first-line treatment for OAB, the treatment is still challenging. Extracorporeal magnetic innervation(ExMI) therapy have been known to be safe and effective immediately in stress urinary incontinence and OAB. The aim of this study was to assess the effect of suprapubic magnetic innervation therapy by arm-typed plate in patients with OAB. Methods : The selected subjects were 32 patients diagnosed with OAB between the periods of April to September, 2007. Mean age was 48.3±10.7 years old, and there were 10 males and 22 females patients. Voiding diary, International Prostatic Symptoms Score(IPSS), quality of life(QOL) questionnaire were evaluated as assessment of voiding symptoms. The treatment was performed for 15 minutes, 2 times a week, for 6 weeks with ExMI by arm-typed plate(BioCon-2000. M-Cube, Korea). All of the evaluations were repeated immediately and 3 months after treatment. Results : The mean urgency episodes decreased from 13.2±1.81 times to 8.7±1.95 times immediately after treatment and 9.6±2.18 times at 12 weeks after treatment(p<0.05). At 6 weeks after starting treatment, the mean frequency decreased from 5.4±1.58 times to 3.6±1.37 times(p<0.05), but the mean frequency after 6 months was 4.3±1.72 times(p>0.05). Significant improvements immediately after treatment were noted in the frequency, urgency, and QOL in IPSS, which were maintained for 3 months(p<0.05). There were improvements in mean voided volume, but these were minimal. Conclusion : The symptoms of OAB are highly prevalent and significantly affect the quality of life. Effective and prompt management of OAB should be implemented. Our datas suggested that the EXMI therapy by arm-typed plate has the favorable effect on OAB and it may be persist for at least 12 months. Further studies are needed to establish the long-term efficacy of EXMI therapy in patients with symptoms of OAB.
화강풍화토 지반에 설치된 압력재주입 그라우팅 보강재의 인발특성

지반보강을 위해 국내에서 널리 사용되고 있는 공법으로 앵커공법, 소일네일 공법 및 소구경말뚝 공법 등을 들 수 있다. 상기 공법의 경우 보강재의 시공은 용도에 따라 구분되지만 공통적으로 보강재를 삽입한 후에 그라우팅 작업을 실시하는 공정이 포함되어 있다. 지금까지는 국내 대부분의 경우 중력식 그라우팅으로 시공되고 있지만 중력에 의해 그라우팅을 실시하기 때문에 천공 시 발생하는 지반이완영역에 대한 복원이 명확지 않아 보강재의 구조적 결함을 유발할 우려가 있다. 반면에 압력재주입 그라우팅은 먼저 그라우트를 채운 후 소정의 시간이 지나고 미리 설치한 튜브를 통하여 추가적으로 재주입하는 방식으로 기존의 그라우팅 방식에서 발생할 수 있는 문제를 상당부분 해결할 수 있어 그라우팅의 품질을 향상할 수 있다. 본 연구에서는 그라우팅 방식에 따른 인발특성을 평가하기 위하여 화강풍화토 지반을 대상으로 모형실험을 실시하였으며, 그라우팅방법에 따른 인발력 변화와 압력 재주입그라우팅의 재주입시기와 재주입압에 따른 보강재 지지력 증대 특성을 평가하고자 하였다. 연구결과 압력재주입식 그라우팅 이 중력식그라우팅에 비해 최소 1.1배에서 1.3배까지 인발력이 크게 발휘되는 것을 확인하였으며, 압력재주입식 그라우팅의 적정물시멘트비, 주입압력 및 재주입시기에 대한 고찰결과를 제시하였다. Most widely methods for reinforcement of soil utilized in Korea are anchor method, soil nail method and micro pile method. These methods are classified by the intended use of the structure to be constructed, but the reinforcement of the ground is accomplished contains in common the process of grouting work after inserting the reinforcements. Domestically, gravity grouting has been used mostly so far, but there has always been the risk of insufficient restoration of the loose ground area from the drill holes because the grouting is conducted only by gravity. On the other hand, pressure reinjection grouting may enhance the grouting quality by solving the problem of the existing grouting method considerably since it additionally reinjects grouting through pre-installed tube a certain time after the first grouting. Accordingly, this study evaluated the pullout characteristics by the grouting methods by performing model test on decomposed granite soil, and investigated the support increasing characteristics of reinforcements depending on the curing time, reinjection pressure, and uplift force variation of the pressure reinjection grouting. The result of this research shows that the pressure reinjection grouting demonstrated 1.1~1.3 times of performance of the gravity grouting, and suggests some analysis on optimal water content, reinjection pressure and curing time of the pressure reinjection grouting.

Ulcers of the small bowel distal to the duodenum are not common, and some ulcers are unexplaned by any specific mechanism and have been termed $quot;nonspecific$quot; or $quot;idiopathic$quot; small bowel ulcer. In Korea, nonspecific ulcer of the small bowel is quite rare, comparison of the western contury. Recently we experienced a patient with nonspecific ulcer of ileum. A 50-year-old male patient was admitted to the hospital because of intestinal obstruction and perforation. By laparotomy, perforation and numerous stenosis were identified in the 55 cm from ileocecal valve, segmental resection has been done. The histologic findings identical to the peptic ulcer suggested the feature of nonspecific ulcer of small bowel. We present this case with the review of literature.
