Purpose: The purpose of this study was to investigate the effect of strengthening exercises of hip abductors on muscle strength and ambulation for patients with ACL reconstruction. Methods: The subjects were randomly assigned to the intervention group (general exercise plus strengthening of hip abductors) or the control group (general exercise without the strengthening of hip abductors). Both groups participated in a six-week exercise protocol after the surgery for ACL reconstruction. The knee strength test (quadriceps, hamstring, hip abductor) and gait analysis were performed in pretest and post-test. Results: Muscle strength was measured using the Biodex system III model (Biodex Medical System, Inc, NY, US). The results showed no significant difference in knee strength (quadriceps, hamstring) between the two groups (p>0.05), however, there was a significant difference in hip abductors (p<0.05). The gait analysis was measured with Gaitrite system (CIR System Inc, US). Results of comparison between groups showed a significant increase in the step length of both groups. (p<0.05), and there was a significant difference in the affected leg of the intervention group(p<0.05). Conclusion: Exercise of hip abductors for patients with ACL reconstruction provides significant benefits with respect to improvement of muscle strength in hip abductors, increasing the stride. This result indicates that a training program designed for ACL reconstruction patients should include strengthening of the hip abductor. We think that further study is needed to determine the relationship of hip muscles and knee joint for patients with ACL reconstruction.

Aggressive angiomyxoma is an uncommon soft-tissue neoplasm which affects the pelvis and genital organs of the young female predominantly. This tumor has a high tendency of local recurrence, but it usually does not develop metastasis. Although surgical excision with wide tumor-free margins may be necessary to obtain a complete cure, some of patients experience local recurrences. Many of the tumors are estrogen receptor (ER) and progesterone receptor (PR) positive and medical therapy with gonadotropin-releasing hormone (GnRH) agonists showed to be effective in a few cases. We present a case of 29-years-old women who has aggressive angiomyxoma which was misdiagnosed as bartholin duct cyst. She was treated by wide local excision with postoperative adjuvant GnRH agonist therapy for 3 months. She is now free of disease during 9 months of follow up. We have described this case with the brief of literature.

It is very important to effectively search for the required documents in the Web that has diverse and huge amount of information.<BR> In term-based Web document search, the search engine shows the user a list of the Web documents that contain the keyword the user wants to find. Such retrieval methods use some weighting mechanism to identify required documents.<BR> In this paper, we present an effective method to calculate the weights of Web documents for term-based Web document search. Most of existing methods count the number of terms occurring in the documents. We give different weights to HTML tags in Web documents and compute the weight of each document accordingly.<BR> We verify the adequacy of our method by comparing the experimental results with other approaches.

Heterotopic pregnancy is an unusual condition that intrauterine pregnancy is accompanied by a coexisting ectopic pregnancy. The incidence of heterotopic pregnancies has increased in recent years because of rising incidence of pelvic inflammatory disease, pelvic surgery, expanding use of assisted reproductive technology. We report a rare case with heterotopic pregnancy following ovulation induction and intrauterine insemination that was diagnosed after rupture of the ectopic pregnancy. After surgical removal of the ruptured left tubal pregnancy, she carried the intrauterine pregnancy to term without any complications.

The reversible posterior leukoencephalopathy syndrome (RPLS) was first described by Hinchey et al. It is characterized by reversible posterior predominant white and gray matter lesions on brain magnetic resonance imaging (MRI) in patients with renal insufficiency or hypertension, or immunosuppression. The findings on neuroimaging are characteristic of subcortical edema without infarction. Patients with RPLS show various kinds of neurologic abnormalities characterized by headache, nausea, vomiting, visual disturbances, altered mental status, decreased alertness, seizures, and focal neurologic signs. The clinical and radiological findings usually resolve within two to three weeks when the underlying cause is removed. In this report we describe the case of RPLS with eclampsia in a 24-year-old woman, which appears to be involved in areas of the occipital, frontal, and parietal lobes. A brief review of the literature is also presented.

LED(Liquid Emitting Diode)프레임 장치는 한국을 대표하는 디스플레이 분야에서 큰 비중을 차지하고 있다. LED는 TV나 모니터, 노트북, 핸드폰 등 에 필수적인 부품이다. 일본이나 대만, 중국 등에서 LED에 대한 투자를 강화하면서 생산성 향상이 중요한 사항이 되고 있다. 하지만 부품의 크기가 점점 작아지면서, 사람의 눈에 의한 일관적이지 못한 검사는 신뢰성이 문제가 되어 LED 모듈 검사 분야에서 자동 검사 공정은 필수적인 사항이 되고 있다. 본 논문에서는 컴퓨터 비전 기술을 이용하여 시각 검사 공정의 결함을 검사한다. LED 프레임에 대한 검사를 신속하고 정확하게 함으로써 공정상의 효율을 높이고 검사시간을 단축하였다. 검사 시스템을 현장에 적용한 결과 빠르고 정확하게 검사가 가능함을 확인하였다. The LED (Liquid Emitting Diode) frame device is a big part of the representative display industry in Korea. LED is an essential part for TV, monitor, notebook, and mobile phone. In Japan, Taiwan, China and other countries, investment in LEDs has been strengthened, and productivity has become an important issue. However, as the size of the parts becomes smaller, the inconsistent inspection by the human eye becomes a problem of reliability, so that the automatic inspection process becomes an essential issue in the field of LED module inspection. In this paper, we investigate defects in visual inspection process using computer vision technology. The inspection of the LED frame is made quickly and accurately, thereby improving the efficiency of the process and shortening the inspection time. As a result of applying the inspection system to the field, we confirmed that it is possible to inspect quickly and accurately.
