Sohn, Moo-Young,Lee, Ja-Eun 國立 昌原大學校 基礎科學硏究所 1994 基礎科學硏究所論文集 Vol.6 No.-

In this paper, we introduce weighted graph bundles and study their characteristic polynomial. In particular, we show that the characteristic polynomial of a weighted K_(2) (??_(2)) bundles over a weighted graph Γ_(ω) can be expressed as a product of characteristic polynomials two weighted graphs whose underlying graphs are Γ As an application, we compute the signature of a link whose corresponding weighted graph is a double covering of that of a given link.

Familial adenomatous polyposis (FAP) is an autosomal dominant syndrome, typically characterized by multiple colorectal adenomas and increased incidence of colorectal carcinomas if it is not treated. Moreover, a variety of extracolonic manifestation are seen. The prevalence of thyroid tumors developing in patients with FAP is about 1∼2%. Generally, papillary thyroid cancer indicates low mortality but ,however, as people get older, the cancer becomes more aggressive. So, the operation is required. Recently we experienced a case of FAP, presenting with papillary thyroid carcinoma, and reported with a brief review of literatures.

Lesions of the anterior and medial parts of the thalamus are often accompanied by memory dysfunction Bilateral lesions may produce major memory deficits that have sometimes been reported to last for several years Unilateral lesion may also be associated with memory dysfunction which is usually less severe and persistent and may be linked to a selective field of memory We report two amnesic patients with isolated infarct in the polar territory of the left thalamus. This cases demonstrate that unilateral left thalamic infarction in the polar territory can be presented with isolated verbal amnesia with relatively preserved visuospatial memory function and lateralization of memory dysfunction after thalamic infarction which is not always present.

The purpose of this study is to suggest fundamental information about wearing method and production of brassiere, which is suitable for physiological hygiene and efficient action for elderly women. The subject is 418 elderly women aged 50~69 years old. Data is processed by a computer(SAS) and is analyzed by using frequency, percentage, χ²-test. The main results of this study are as follows: 1. Elderly women' weight and breast size are higher than their younger counterparts' in their 20's. but the older and poorer women with more children have smaller weight and breast. Most of the elderly women feel that their breasts are drooped or falling apart. In fact, those elderly women who gave birth to more children have more drooped and wider breasts. the major type of elderly women' breasts is the drooped breast' featured by those elderly women who have more children. 2. Most of the elderly women began to wear the brassiere for the first time in their 20's. the older women with more children began to were the brassiere earlier, while those less educated and poorer began to protect their breasts with brassiere later. Many elderly women were the brassiere to be protected from dirt, noise or look more neat, but day tend to wear the brassiere not all day around but at certain times, older, less educated and poorer women with more children tend to use the brassiere for etiquette and less often. This group of elderly women feel tedious, strange or uncomfortable for the brassiere. 3. Most of the elderly women know about their brassiere size. Such variables as age, education and income are correlated positively with the interest in and conscious ness of the brassiere size. All in all, the statistical distribution of elderly women's brassiere size is very wide, while most of them use 90A, 85A and 95A sizes. On the other hand, the most popular size for the under bust circumference is 85~90cm, while their primary cup size is A.

Actinomycosis is a chronic suppurative infection, whitch infiltrates mucosa-associated tissues. Thoracic, pelvic and cervicofacial infections of actinomyces are not uncommon, but endobronchial actinomycosis is rarely reported. We report a case of a 29 year old man who presented with a recurrent pneumonia and chronic cough. Fiberoptic bronchoscopy revealed occlusion of the right. lower medio-basal segment bronchus with exophytic endobronchial mass. The diagnosis was confirmed histologically by demonstration of sulfur granules in the bronchoscopic biopsy of the mass. Intravenous administration of amoxacillin and clindamycin followed by oral amoxacillin and clindamycin therapy resulted in complete recovery.

Backgroud : This study is to identify preoperative patient characteristics associated with a lack of improvement on one or more measures perioperatively, postoperative 3-4 months, and postoperative 12 months. Methods : For the assessment, prospective study was performed with 92 patients who had undergone either one eye or both eye cataract surgery by 3 ophthalmologists practicing at a university hospital. The criteria of improvement were (1) Snellen visual acuity, (2) a cataract-related symptom score(possible range: 0. 0 of 6 symptoms present or bothersome, to 18. all 6 symptoms very bothersome), and (3) VF-14 score - a measure of functional impairment in patient with cataract - (possible range: 0, inability to perform any of the applicable activities, to 100, no difficulty in performing any of the applicable activities). Results : Although 14 patients (15.2%) failed to improve on one or more of the outcome measures assessed, no one failed to improve on all three measures. Both eyes of surgery than one eye, preoperative cataract symptom score of 1-4, 5 or higher than 0 were associated independently with the increased likelihood of improvement (odds ratio 8.95, 7.16, 8.87 respectively). And the preoperative level of Snellen visual acuity was not associated with the likelihood of improvement Conclusion : We conclude that specific preoperative characteristics (both eyes, cataract symptom score) are independent predictors of patient outcome after cataract surgery,

본 연구에서는 Mg₂SiO₄에 활성화 물질로 La, Ho를 첨가하여 열형광체를 제작하였고 불순물의 농도를 1wt.% ∼5 wt.%까지 변화시키면서 열평광강도의 glow curve를 측정하였다. 도한 열형광체의 glow curve를 peak shape법으로 분석해서 TL특성에 대한 포획 매개변수와 활성화 에너지, 발광차수, 선량의존성등을 조사하였으며, 그 물리적 특성을 조사하고 선량계로서 타당성과 실용성을 확인하였다. The Mg₂SiO₄: La, Ho thermoluminescent phospher has been prepared by sintring Mg₂SiO₄after doping the transition elements La and Ho. The heating rate is 10℃/sec at this thermoluminescent phospher are heated. The maximum peaks are found in the measured Mg₂SiO₄: La and Ho. TL glow curve at 229℃ and 345 C when the 1 wt.%-5 wt.%. The glow curve of TLD increased TL intensity and temperature of peak appears to the high temperature when the heating rate is l0℃/sec-25℃/sec. The activation energy of the main peak has been estimated by the peak shape method. The estimated activation energies are 1.77 eV. 1.52 eV respectively. The thermoluminescence process in Mg₂SiO₄: La and Ho are found to the 2nd order when the main peak of the glow curve is analyzed by peak shape method. The dose responses of Mg₂SiO₄: La and Ho TLD are linear up to intensity of X-ray.

Background: Cerebral white matter changes can be observed frequently in Alzheimer′s disease or healthy elderly as well as vascular dementia the clinical significance and injury mechanism of cerebral white matter changes have not been clarified Objectives: To evaluate the significance of cerebral white matter changes in elderly patients Methods: We assessed cognitive function and radiological features in patients with white matter changes to evaluate the effect of cerebral white matter changes and cortical central brain atrophy on cognition Grading of white matter changes was measured by the Scheltens scale The cortical atrophy was graded with visual inspection by two independent neurologists and the central atrophy was assessed with ventricular indices The cognitive status was evaluated with Mini-Mental state examination and the modified Mini-mental State examination Results: Identified risk factors for white matter changes were older age, hypertension, and female gender The degree of cerebral white matter changes was significantly associated with cognitive disturbances and their main effect on cognition was fluency and attention deficits There was no difference in the severity of cortical atrophy between the two groups Visual rating for cortical atrophy and measurement of ventricular indices showed good intra-and -observer reliability Conclusion: Our results support the hypothesis that cerebral white matter changes contribute to cognitive disturbances, especially frontal lobe dysfunctions in elderly irrespective of cortical brain atrophy.
