Stroke is one of the most important diseases in the elderly, but studies on the elderly stroke(age ≥70 years) are rare. The authors evaluated clinical characteristics of ischemic stroke in the elderly and compared them with those in the young(age ≤69). The conclusion obtained are as follows. 1. The strokes with multiple risk factors and combined diseases were more common in the elderly than in the young. 2. Middle cerebral artery territory was most frequently involved in the two groups, but vertebrobasilar territory was more frequently involved in the elderly than in the young. 3. The incidence of recurrent stroke and pathogenesis did not differ significantly between the two groups. 4. Among the complications, urogenital diseases were more common in the elderly than in the young.

Spain is one of the few countries that have successfully consolidated democracy. The task of consolidation has, however, formidable, for Spain has lacked a political tradition of toleration as well as an institutional mechanism of consensus building. The Spain history abounded with coups and civil wars: Franco had also left a repressive regime whose taming was vital for assuring a smooth transition toward civilian politics. In response, the heterogeneous democratic forces signed a Moncloa Pact of 1977 and opted for a consensual drawing of Spain's new constitution. They relied on the force of example and economic encouragement to consolidate the pluralist form of political organization, and defended their internal unity against centrifugal forces by emphasizing pacts and compromises. The taming of Spain's military occurred within such a broad political strategy of consensus building. The new regime was careful not to alienate the moderates within the military and presided over a concerted effort to win the loyalty of the army as an institution. Salaries were raised: equipments were modernizied: and Spain's participation in Europe-wide military exercises were promoted. The new regime also pushed for a merger of the military hierarches and branches: it drew a sharper distinction between the civilian and military spheres of life as well. Defended as measures to enhance the professionalism of the military, the reforms had an objective of consolidating the civilian control over the military. The democratic consolidation in Spain was, in short, based on a political strategy that consciously tried to reduce the fears which the military harboured against the democratic regime by making the political reforms to serve the institutional interests of the military as a whole.

Background and Objectives: Sniffin' Sticks test is the test of nasal chemosensory performance based on pen-like odor dispensing devices. KVSS(Korean Version of Sniffin' Sticks) Test was developed as the "Korean olfactory test" using the odorants which are familiar to Korean. Authors evaluated the clinical validity of KVSS Test compared with CC-SIT (Cross-Cultural Smell Identification Test) in Korean. Materials and Methods: The subjects of this study were 25 normosmic volunteers who were divided into five groups according to age. Each group was 5 normosmic volunteers. And they consisted of 12 men and 13 women. KVSS Test and CC-SIT were used for the evaluation of olfactory function. Results: Our study showed the negative correlation between age and olfactory function test (CC-SIT score, KVSS Test I score and KVSS Test II score). Normosmia rate of KVSS Test was more higher than that of CC-SIT. Also KVSS Test had more familiar items for Koreans compared with that of CC-SIT. CC-SIT score and KVSS Test score showed showed the positive corrclation. And each test revealed high reliability in test-retest evaluation. Conclusion: The KVSS Test can be used as an olfactory function test for Koreans.

Pt was deposited on carbon support by chronoamperometry. The catalytic activity for methanol oxidation was checked by CV (cyclic voltammetry) method. The amount of Pt loading was calculated by integration of I-t curve obtaining the total current used for the Pt deposition. The ECA (electrochemical active surface area) for loaded Pt was calculated from the hydrogen adsorption/desorption peaks in 0.5 M H₂SO₄solution. Pt was deposited on clean carbon electrode surface with various concentration of Pt solution (0.1 mM) was used. As the concentration of Pt increased, the specific catalystic activity of Pt decreased suggesting that, in the electrochemical reaction of Pt ion with electrode surface, Pt particles were smaller and more dispersed in low concentration of Pt solution. With this condition (0.1 mM Pt), Pt was electrodeposited on a commercial carbon support, Vulcan XC-72. Electrochemically loaded Pt catalyst had the higher ECA, and showed higher specific catalytic activity for mathanol oxidation than a commercial Pt/C catalyst.

Background and Objectives: Rhinosinusitis is the most common cause of olfactory impairment and endoscopic sinus surgery is considered as a surgical procedure of choice for treating chronic sinusitis. CC-SIT (Cross-Cultural Smell Identification Test) consists of 12 items well known in most non-English-speaking cultures. Authors evaluated the therapeutic effects of endoscopic sinus surgery on olfactory dysfuction using CC-SIT. Materials and Methods: The subjects of this study were seventeen sinusitis patient who had undergone ESS from November 2001 through April 2002. All patients were divided into two groups according to nasal polyp and CT findings. CC-SIT was used for the evaluation of olfactory function. Results: Forty seven percents of patients had improvement in olfactory function postoperatively. No correlation was found between changes in CC-SIT score and nasal polyp and preoperative CT findings. Conclusion: It is concluded that nasal polyp and CT findings have no effect on olfaction.

Background and Objectives: Benign tumors of the nose and paranasal sinues are rare in comparison with malignant growths. Authors aimed to investigate the incidence and characteristics of benign sino-nasal tumors. Materials and Methods: From 1994 through 2004, 25 cases of benign sino-nasal tumors (17 men and 8 women) were diagnosed and cared at the Department of Otorhinolaryngology-Head and Neck Surgery, College of Medicine, Konkuk University. We reviewed medical records of patients to find out clinical features, radiologic findings, operative findings, therapeutic options, and outcomes. Postoperative observation was given for fifteen months on the average. Results: The most common symptom was nasal obstruction, followed by nasal mass, frequent nasal bleeding, headache, and rhinorrhea, and the mass mainly placed in the lateral nasal wall. There were 12 cases (48%) of inverted papilloma, 4 (16%) cases of squamous papilloma, 4 (16%) cases of hemangioma, 1 (4%) case of pleomorphic adenoma, 1 (4%) case of leiomyoma, 1 (4%) case of lipoma. All the tumors were surgically removed. For the treatment of inverted papilloma, medial maxillectomy had been performed before 1997(2 cases); however, most cases have been managed with endonasal endoscopic technique since 1997. Recurrence was observed in two patients with inverted papilloma and one patients with squamous papilloma. Conclusion: Inverted papilloma is the most common benign tumor in the nose and paranasal sinuses, followed by squamous papilloma and hemangioma. The optimal management of benign tumors is complete excision of tumor and endonasal endoscopic surgery is an effective treatment for an inverted papilloma.

Bursaphelenchus xylophilus has been recognized as a causal pathogen of pine wilt disease (PWD). In order to identify relevant molecular biomarkers, we selected a variable region of endo-β-1,4-glucanase (β14-gcn) which was cloned from the cDNA of B. xylophilus and B. mucronatus. We then identified three novel β14-gcn isoforms: Bm-β14-gcn and Bm-β14-gcni from B. mucronatus, and Bx-β14-gcn from B. xylophilus. Bm-β14-gcn and Bx-β14-gcn were found to be identical, whereas Bm-β14-gcni was unique to B. mucronatus. These isoforms are Bursaphelenchus-specific and may be employed as molecular markers for the diagnosis of PWD. Our phylogenetic analysis showed that these β14-gcns from Bursaphelenchus species were associated most closely with fungal β14-gcns.

TEPC (Tissue Equivalent Proportional Counter) was usually used for high LET radiation dosimetry. We developed a prototype TEPC for micro-dosimetry in the range of 0.2~300 keV/μm. And, the simulated site diameter of the TEPC is 2 μm, of similar size to a cell nucleus. For purposes of characterization the response for high LET radiation of the TEPC has been investigated under 135MeV/u Carbon ions in HIMAC (Heavy Ion Medical Accelerator). We determined the gas multiplication factor and measured the lineal energy spectrum [yd(y)] of 135 MeV/u Carbon ions. The value of the gas multiplication factor was 315 at 700 V bias voltage. As a result of the experiment, we could more understand the performance of the TEPC for high LET (Linear Energy Transfer) radiation. And the procedure of high LET radiation dosimetry using TEPC is established.
