Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

This paper analyses an architecture of network-based control system and deals with its application using the CAN protocol. It is difficult to determine an optimal network architecture for a specific system. In this paper, we propose the architecture of network-based control system applicable to a specific AGV system with manipulator arms. The fixed number of periodic messages to be occurred in pre-defined in this system. These messages are scheduled by applying the DMS algorithm. To determine whether the proposed system architecture is effective or not, we perform traffic analysis for the real-time communication of all messages. Through simulation, the possible maximum transmission speed is found and the number of possible sensors to be added is investigated for improving the system performance, when the sampling period of an analog sensor is determined under fixed condition that transmission speed is over 500Kbits/sec.

The purpose of this study was to evaluate change of path length center of body on sacroiliac joint mobilization. The subjects were consisted of sixty healthy adult two decade(28 females. 32 males; mean aged 22.2) from 20 to 29. All subjects randomly assigned to the control group, sacroiliac joint mobilization group. sacroiliac joint mobilization group received sacroiliac joint mobilization for 2-3 minutes per day and three times a week during 3 weeks period. The study carried out to determine the change of path length center of body on sacroiliiac joint mobilization from July 1, 2004 through september 30, 2004. Active balancer(SAKAI EAB-100) was used to measure equilibrium ability. All measurements of each subjects were measured at pre-experiment and post-experiment. The results of this study were summarized as follows : 1. The WPL of control group, sacroiliac joint mobilization group was no significantly differences at pre-experiment but significantly reduced post-experiment(p<.05). The results of analyzed effects of WPL was significantly reduced between experiment type of control group, sacroiliac joint mobilization group according to pre-experiment and post-experiment(p<.05). 2. The UPL of control group, sacroiliac joint mobilization group was no significantly differences at pre-experiment but significantly reduced post-experiment(p<.05).The results of analyzed effects of UPL was significantly reduced between experiment type of control group, sacroiliac joint mobilization group according to pre-experiment and post-experiment(p<.05). Conclusionally these data suggest that a 3-week S-I joint mobilization improved equilibrium. Additional randomized controlled trials to more fully investigate treatment effects and factors that may mediate these effects are needed.

We report the reorganization of motor network resulted from intensive unilateral coordination training and the effect of cross education on the untrained side in patient with traumatic brain injury using functional magnetic resonance imaging (fMRI). A 22 year-old male patient who had suffered from diffuse axonal injury for 58 months showed coordination deficit in the left hand at initial examination. Intensive motor training including complex finger movements and coordination activities using a metronome was introduced to the patient 4 hours per day for a week. FMRI was performed on a 3T ISOL Forte scanner. All functional images were analyzed using SPM-99 software. Hand function was improved after training not only in the trained lefr hand, but also in the untrained right hand. There was no activation in the right primary motor area (M1) during left hand movement before training whereas robust activation of left M1 was demonstrated by the right hand movement. Profuse activation of bilateral prefrontal lobes was seen during both hand movements before training. After training of left hand, right M1 became prominently activated during the left hand motion. The activation of bilateral prefrontal lobes disappeared after training not only for the left hand movement but also for the right, which clearly demonstrated the effect of cross education. This case report demonstrated the learning-dependent reorganization of the M1 and the effect of cross education.

본 논문에서는 메트로 옵티컬 이더넷의 소프트웨어 구조에 관한 연구를 위하여 10기가 비트 이더넷 스위치에 적용될 QoS 지원 소프트웨어의 적용성을 자원할당 방식 시그널링 프로토콜인 RSVP와 트래픽 특성에 따라 CoS를 구분하는 DiffServ가 10 기가비트이더넷 스위치에 활용 가능한지를 네트웍크 프로세스 처리 능력과 확장성 측면에서 분석하였다. 결론적으로 RSVP, Diffserv와 802.1p는 구현 및 상혼 연동이 가능하다. 그러나 이것은 기업 내부망으로 한정된다는 단점을 가지고 있다. 일반적으로 중소규모의 특정 기업의 내부망에 위의 기술들을 구현하는 것은 어려움이 없다. 그러나 공중망에서의 적용은 아직까지는 어려움이 많이 존재하며 서비스 제공자간의 연동은 거의 불가능하다. 따라서 이러한 기술들은 End-to-End QoS를 보장하는 것에 목적을 두고 있다.

본 실험은 일반 가정의 식탁에서 흔히 볼 수 있는 산채류 20종에 대해 3주의 gram 양성균(Bacillus subtilis, Lactobacillus casei, Staphylococcus aureus)및 2주의 gram음성균(Klebsie-lla pneumoniae, Shigella sp.)의 성장에 미치는 영향을 조사하였다. 본 실험에 사용한 대부분의 산채류 추출액은 공시균의 성장을 다소 증가시켰다. 특히 표고버섯과 고사리는 그람양성균인 B.subtilis, L.casei, S.aureus균의 취, 더덕과 토란은 B.subtilis, S. aureus균의 성장을 대조군에 비해 2~6배로 크게 증가시켰다. 그러나 그람음성균인 K.pneumoniae와 Shigella sp.에 대해서는 성장을 크게 증가시키는 시료는 없었다. 한편, 죽순은 B.subtilis의, 부지깽이와 민들레는 L.casei의, 팽이버섯과 돌나물 및 두릅은 S. aureus의, 산초, 다래순, 두릅 및 마는 K. pneumoniae의, 죽순, 두릅 및 마는 Shigella sp.의 생육을 다소 저해하는 것으로 나타났으나 항균력은 인정할 수 없었다. This study was carried out to investigate how to influence mountainvegetables, which are commonly available in high mountains in Korea, on bacte-rial growth. Total 20 kinds of mountain vegetables and mushrooms were sampledand after boiling them in water, put water extracts of them into the media prepa-red for the smear of test strains, which were included three of Gram positivestrains (Bacillus subtilis, Lactobacillus casei and Staphylococcus aureus) andtwo of Gram negative strains(Klebsiella pneumoniae and Shigella sp.). The gro-wth of all strains were more or less increased in the media injected with waterextracted samples than that of the control. Especially the growth of B. subtilis,L. casei and S. aureus were increased by the water extracts of Pyogo mushroomand Bracke and the samples from Aster, Deodeok(Codonopsis lanceolata) andTaro were appeared with the increase in growth of B, subtilis and S. aureusby two to six times increase rate than that of control. However, the more growthincrease of K. pneumoniae and Shigella sp. were not found than that of control.There were also observed some of water extracted samples have slight inhibi-tions to the bacterial growth. The growth of strains inhibited by the sampleswere as follows .B. subtilis by water extracts of Bamboo shoot, L. casei bythem of Busiggaengi(Erysimum aurantiacum) and Dandelion, S. aureus by themof Pengi mushroom, Sedum and Fatsia, K. pneumoniae by of them of Chinesepepper, Darae(Actinidia arguta) , Fatsia and Yam and Shigella sp. by of themof Bamboo shoot. Fatsia and Yam. However. these antibiotic effects were soweak that scarecely proved their effects.

In this paper, we propose an efficient content-based image retrieval method using the color and wavelet based pattern features. The pattern features are extracted from the invariant moments of the high-pass band image through spatial-frequency analysis of wavelet transform and color features are extracted from color histograms of the global image. The proposed image retrieval method is called a pattern and color feature based query(PCBQ). Forward PCBQ and backward PCBQ perform similarity matching of cascade form using the pattern and color features. The first step matching is carried out to find the candidate images which are most similar to the query image using the pattern or color features. The second step matching is executed using the feature vectors for the accurate retrieval from the candidate images of the first step. Weighted PCBQ performs weighted similarity matching of parallel form using the pattern and color features. The experimental results show that the proposed retrieval systems yield more improved retrieval accuracy than the previous methods.

객체 지향 방법은 많은 장점을 가지고 있지만, 지금까지 발전시켜온 전통적인 방법을 버릴수 없다든지, 객체 지향 기법의 전문가가 많지 않기 때문에 성공의 보장도 확실하지 않는 이유들 때문에 시스템 개발에 쉽게 수용 하지 못하고 있다. 구조적 분석 방법을 객체 지향방법으로 변환하려는 노력이 많아지고 있지만 정형화된 방법은 없다. 본 논문에서는 전통적인 구조적 분석 모델로부터 객체 지향 모델로의 변환방법을 검토하고 구조적 분석 모델, 즉 자료흐름도,자료사전,개체관계도 모델로부터 객체지향의 대표적 모델인 OMT의 객체모델로의 사상에 대한 새로운 방법을 제안한다.

Despite research to treat delayed onse muscle soreness(DOMS), no effective treatment has been reported. The purpose of this study is to investigate the effect of a hold-relax technique and cryotherapy on DOMS. Thirty-three subjects were randomly assigned to one of three treatment groups: control, hold-relax technique, or hold-relax technique and cryotherapy. DOMS was induced in the non-dominant biceps muscle through repeated eccentric contractions. Resting elbow joint position, flexion and extension(universal goniometer), pain(Visual Analogue Scale; VAS), and WBC count(blood analysis) were measured one hour before DOMS was induced and 24, 48, and 72 hours after DOMS was induced. The data were analyzed by repeated measure of two-way ANOVA. The results of this study were summarized as follows: 1) While analysis showed no significant differences between groups in relation to resting elbow joint position, there were significant differences over time, especially at 24, 48 hours after DOMS was induced compared with resting elbow joint position before DOMS was induced. 2) While analysis showed no significant differences between groups in relation to range of flexion, there were significant differences between rage of flexion before DOMS was induced and range of flexion 72 hours after DOMS was induced. 2) There were no significant differences between groups or over time in relation to range of extension. 4) While analysis showed no significant differences between groups in relation to VAS, there were significant differences over time in different hours. 5) There were no significant differences between groups or over time in relation to WBC count. 6) There were no interactions between groups or over time in all variables. This results suggested that hold-relax technique and cryotherapy were not effective to reduce DOMS.
