Many kinds of material have been researched and analyzed to get the essential guidelines for developing physics CAI courseware which is capable of using in WWW. It has turned out that it enables to enhance the courseware quality and productivity to use the following functions such as communication, presentation, branching and interactivity basically provided by web environment. It has also turned out it is necessaw to use the distributed processing like JAVA for physics simulation courseware. JAVA applet, which simulates projectile motion, has been made and inserted in the physics home page. The experimentation results through WWW are following: 1. In spite of the small file size of 14 kbyte, it makes animation processing and video/sound production much easier. 2. JAVA apple enables it possible for the learners to interact with simulator. 3. It shows just 1% below performance error. Those result show that the JVVA applet is practical and effective enough for physis class.

Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

연구배경: 1978년 란셋 잡지에 보라색 소변에 대한 보고가 최초로 있은 이래, 이 현상에 대한 생화학적, 미생물학적, 임상적 규명이 있었다. 보라색 소변은 환자나 환자 가족에게 불편하거나 걱정스러운 질병이다. 그러나 대개의 경우 환자의 건강에 실제적인 위험이 되는 경우는 거의 없다. 심지어 보라색 소변은 열심히 치료할 필요가 없다고 주장하는 사람도 있다. 이에 대조군 연구를 통하여 보라색 소변의 위험요인과 임상적인 의미(심각성)에 대하여 평가를 하고자 한다. 방법: 2007년 2월부터 4월 사이에 인천은혜병원에 입원하고 있는 381명의 환자들 중 도뇨관을 삽입하고 있는 65명을 대상으로 하였다. 이 65명은 65세 이하이거나 1개월 이하동안 도뇨관을 갖고있는 환자는 제외한 숫자이다. 대상 환자는 모두 실리콘제의 폴리카테터와 일회용 소변주머니를 사용하였고 카테터의 교환주기는 특별한 경우 외에는 1개월마다 교환하였다. 대상환자 중 16명이 보라색 소변을 보여, 멸균생리식염수로 방광세척을 한 뒤 카테터와 소변 주머니를 소독된 새 것으로 무균적으로 교환한 뒤 소변배양을 실시하였다. 관련 환자와 대조군의 비교항목들을 통계처리하여 통계적인 유의성을 확인하였으며, 변수의 분석은 신뢰도 95%로(P value 0.05) 카이스퀘어 가설검정과 만-휘트니 U검사를 실시하였다. 결과: 보라색 소변을 보였던 환자들의 나이 평균은 80세였고 전원이 와상상태의 할머니였다. 대상환자의 진단명 중 가장 많은 것은 치매였다. 평균 도뇨기간은 22개월 이었다. 보라색소변을 보인환자군은 보이지 않은 환자들 보다 평균 도뇨기간이 길었으며, 변비가 더 심하였고 변비치료용 좌약 사용빈도가 높았다. 대조군에서는 조사기간 전 1개월 이내에 항생제를 사용한 빈도가 약간 더 높았으나 통계적인 의미는 확실하지 않았다. 결론: 보라색소변은 장기요양노인병원에서 흔히 발생하는 문제이다. 이전 연구들에서 없었던 보라색 소변과 항생제사용과의 관련성 및 변비치료제로 bisacodyl 좌약사용과의 관련성, 소변 카테터의 삽입기간 등에 대한 정보를 추가하여 얻을 수 있었다. Background: Since the first report of purple urine bag syndrome (PUBS) by Barlow and Dickson in 1978, many researchers have tried to reveal the clinical and bacteriological background of this phenomenon. To the best of our knowledge, most of them were case or case series reports and only three were case-control studies which compared the clinical, biochemical, or bacteriological background between patients with and without PUBS. It is certain that PUBS is an uncomfortable or troubling issue for some patients and their families. However, most of the patients who presented with PUBS were, largely, asymptomatic and it is apparent that PUBS is not a disease per se, nor does it appear to represent any real danger to patient's health, and some authors go so far as to even advocate that it is unnecessary to treat PUBS-affected patients aggressively. In this case-control study, we reviewed risk factors and clinical significance of PUBS in geriatric wards. Methods: Of the 381 hospitalized patients in a hospital specialized in the long term care of the elderly handicapped (Incheon Eun-Hye Hospital, Incheon, Korea), 65 patients who featured urinary catheterization during the period from February 2007 and April 2007 were enrolled in this study. Subjects who were younger than 65 or catheterized duration was less than one month were excluded. The same types of silicone Foley balloon catheter and disposable plastic urine bag were used for all patients. Routine Foley catheter change interval was one month. For the 16 patients who exhibits PUBS, bladder irrigation with normal saline and immediate change of urine bag and catheter were performed. And urine culture was done. Variables were statistically analyzed by chi square test or Mann-Whitney's U-test. P values less than 0.05 were considered statistically significant. Results: The PUBS patients mean age was 80, and bed ridden female. Most common diagnosis was dementia. Mean duration of the catheterization was 22 months. The PUBS patients were more constipated than non-PUBS control group and used more bisacodyl suppository. Antibiotics usage within one month before this survey in PUBS group is more frequent than control group with borderline statistical significance. Conclusion: PUBS is frequently occurring problem in long-term care geriatric wards. Causative factors are tryptophan putrefaction (decreased intestinal absorption, motility), alkaline urine, oxygen (air, Foley catheterization). All factors are bacterial infection related. Our results were the same as previous results. Relationship with antibiotics usage, bisacodyl suppository and constipation, long term usage of the Foley catheter notified also. Female predomination is related with easy, frequent urinary infection, and more population in old age.

Tracheobronchopathia osteoplastica is a rare disorder of unknown cause characterized by the projection of numerous bony or cartilaginous submucosal nodules into the tracheobronchial lumen with sparing of the posterior membranous portion of tracheobronchial tree. In the past, most of the cases were diagnosed as secondary finding at autopsy. Nowaday, the key component of the evaluation is flexible fiberoptic laryngoscopy and bronchoscopy, which typically demonstrates irregular spicules of subrnucosal bone and cartilage projecting into the tracheobronchial lumen and causing various degrees of airway obstruction. A 45 years old man was visited Sunchon St. Carollo hospital due to discomfort on throat. We saw several nodules just below vocal cord via laryngoscope. The computed tomography revealed multiple small calcified nqdules on trachea and both main bronchi. Pathologic finding of bronchoscopic biopsy showed abnormal proliferation of bony and cartilagious nodules in the tracheal submucosa. These fingdings were consistent with tracheobronchopathia osteoplastica. We report here on a case of tracheobronchopathia osteoplastica with review of literature.

Necrotizing fascitis is a severe soft tissue infection characterized by extensive necrosis of superficial fascia, suppurative fascitis, vascular thrombosis, widespread undermining of surrounding tissues. Accociated systemic problems are widespread undermining of surrounding tissues, Accociated systemic problems are common, with chronic alcoholism and diabetes being most prominent. Most commonly this disease presents in the extremities, trunk, and perineum. Necrotizing fascitis of dental origing is rare and its fulminating clinical course is not well documented in the dental literature. The present report is a case of necrotizing fascitis following vital extirpation of the pulp in a patient with uncontrolled diabetes mellitus and liver cirrhosis. Originally throught to be caused by hemolytic streptococcus organism or stphylococcus aureus, advances in anaerobic culturing have shown it to be a synergistic bacterial infection involving aerobic and ovligate anaerobes. it is relatively rare in relatively rare in haea and neck regions. If it was not diagnosed and treated in early stages, necrotizing fascitis can be potentially fetal, with a mortality rate approaching 40%. It's treatment requires early recognition, prompt and aggressive surgical debriment and proper supportive cares, such as, antibiotic therapy, fluid resuscitation and correction of metabolic and electrolyte disorder, resolving of the underlying systemic disease. Recently, we experienced two cases of necrotizing fascitis in cervicofacial region, One patient was 60 years old male with uncontrolled Diabetes Mellitus and other patient was 48 years old with steroid therapy during 30 years. Local surgical wound healing was successful but, patients were died after admission, because of lung abscess, gastrointestinal bleeding, septic shock and respiration hold.

Pseudomembranous colitis, caused by altering the normal colonic flora and allowing the multiplication of Clostridium difficile, is an deleterious adverse effect of antibiotics. But it is rarely reported by rifampicin. Rifampicin is one of the first line drug in the treatment of tuberculosis and many patients are exposed to its potential adverse effects. We experienced a patient that had abdominal discomfort and hematochezia due to pseudomembranous colitis after receiving antituberculous medication, and which was probably caused by rifampicin. A 82 years old man was admitted with abdominal discomfort and hematochezia for one week. On the past history he had been diagnosed as endobronchial tuberculosis about 4 months ago. Colonoscopy revealed multiple discrete whitish mucosal lesion on rectosigmoid colon, and histologic findings were consistent with pseudomembranous colitis. The antituberculous agents were discontinued and vancomycin was administered. The patient's symptoms were resolved within several days. There was no recurrence after reinstitution of the antituberculous agents excluding rifampicin. We report here on a case of pseudomembranous colitis probably due to rifampicin.

The purpose of this study is to report the effect of combined acupuncture treatment on acute ankle sprain patients. The subjects included in this study were 15 acute ankle sprain patients who visited Jaseng Hospital of Korean Medicine from Oct. 15th, 2012 to Feb. 8th, 2013. We treated 15 patients with combined acupuncture treatment. The treatment con-sisted of Hwangrunhaedok-tang (Huanglianjiedutang) pharmacupuncture, electroacupunc-ture (applied to GB39, ST36 on the affected side), acupuncture (applied to TE17, SI6 on the unaffected side with Dong-Qi therapy). To assess the effect of treatment, the numeric rating scale (NRS) was applied before and after treatment. After first combined acupuncture treat-ment, the NRS scores significantly decreased from 8.33±0.94 to 2.26±0.44 (p<0.01). We suggested that Combined acupuncture treatment are effective and useful on acute an-kle sprain. And, further studies will be needed. (J Korean Med Rehab 2014;24(1):119-123)

Background: Sentinel lymph node biopsy (SLNB) of primary melanomas as an important diagnostic method has not been popular in Korea yet but has to be set up for its reasonable management. Objectives: To examine clinical feasibility and analyze result of SLNB cases in Kyungpook National University Hospital over recent 10 years. Methods: The data of SLNB in KNUH from 2006 to 2015 were analyzed in terms of detection rate, positivity rate, positivity-relevant overall survival and side effect. Results: A total 121 patients (56 males (46.3%) and 65 females (53.7%)) ranged in age from 33 to 93 years (avg.: 59.8±12.2). The mean Breslow thickness was 3.76 mm, and the proportion of ulcerated melanomas occupied 62.8%. Sentinel node detection rate was 98.3% (119/121). Twenty seven had a tumor-positive SLNB (22.7%) and subsequently underwent completion lymph node dissection (CLND). Metastasis-positive nodal basin after CLND was detected in 9 of 27 patients (33.3%). Negative SLNB cohorts showed better overall survival than positive cohorts with a significant difference (p < 0.05). Two side effects, 1 seroma and 1 lymphocele, were observed without major sequelae. SLNB procedure was undertaken by dermatology (85 pts, 70.2%) and other departments like general surgery (36 pts, 30.0%). Conclusion: SLNB, which is crucial for the management of malignant melanoma, could be done successfully and safely by the cooperation of dermatology and other surgical departments in Korea.

Background: Trichophyton (T.) verrucosum is a dermatophyte causing ringworm in cattle, distributed worldwide. It can be responsible for various inflammatory lesions of skin and scalp. In Korea, kerion celsi caused by T. verrucosum was first reported at 1986 in the southeast province of Korea. Since then, many patients infected with T. verrucosum have been reported in Young-nam province. There are few long-term studies about epidemiological characteristics of T. verrucosum. Objectives: To investigate the clinical and epidemiological characteristics of T. verrucosum infections in Korea. Methods: A total of 224 patients were diagnosed as T. verrucosum infection by fungal culture from 1976 to 2015. The data were based on a retrospective survey of medical records. Results: The annual incidence of patients with T. verrucosum infection had been increasing since the report in 1986. The number of patients showed a peak in 1988. After 2000, the number of patients had been decreasing. Female to male ratio showed a 1.2-fold predominance of female infection. And more than 15-year-old group was 59.4% of total patients. T. verrucosum infection was most commonly seen in spring and was found predominantly in patients living in rural areas. Face was most frequently involved, followed by arms. Conclusion: These findings provide useful information for understanding of T. verrucosum infection and future dermatophytosis prospects.
