  • Background: Vincristine-induced peripheral neuropathy is a major dose limiting side effect and thus effective therapeutic strategy is required. In this study, we investigated the antinociceptive effect of memantine and morphine on a vincristine-induced peripheral neuropathy model in rats. Methods: Male Sprague-Dawley rats weighing 220-240 g were used in all experiments. Rats subsequently received daily intraperitoneal injections of either vincristine sulfate (0.1 ml/kg/day) or saline (0.1 ml/kg/day) over 12 days, immediately following behavioral testing. For assessment of mechanical allodynia, mechanical stimuli using von Frey filament was applied to the paw to measure withdrawal threshold. The effects of N-methyl-D-aspartate receptors antagonist (memantine; 2.5, 5, 10 mg/kg intraperitoneal), opioid agonist (morphine; 2.5, 5, 10 mg/kg intraperitoneal) and vehicle (saline) on vicristine-induced neuropathy were evaluated. Results: Mechanical allodynia developed over the course of ten daily injections of vincristine relative to groups receiving saline at the same time. Morphine abolished the reduction in paw withdrawal threshold compared to vehicle and produced dose-responsiveness. Only the highest dose of memantine (10 mg/kg) was able to increase paw withdrawal threshold compared to vehicle. Conclusions: Systemic morphine and memantine have an antinociceptive effect on the vincristine-induced peripheral neuropathy model in rats. These results suggest morphine and memantine may be an alternative approach for the treatment of vincristine-induced peripheral neuropathic pain.

  • This paper proposes a new fire-flame detection method using probabilistic membership function of visual features and Fuzzy Finite Automata (FFA). First, moving regions are detected by analyzing the background subtraction and candidate flame regions then identified by applying flame color models. Since flame regions generally have continuous and an irregular pattern continuously, membership functions of variance of intensity, wavelet energy and motion orientation are generated and applied to FFA. Since FFA combines the capabilities of automata with fuzzy logic, it not only provides a systemic approach to handle uncertainty in computational systems, but also can handle continuous spaces. The proposed algorithm is successfully applied to various fire videos and shows a better detection performance when compared with other methods.

  • Many libraries have recently become enlarged and industrialized. Spaces dedicated to natural environments and climates in libraries have been isolated, and spaces that take natural environments into consideration have only recently started to receive attention. People all around the world enjoy reading books in nature. Reading is interpreted as the same context as the desire to go somewhere higher. Contemporary people have discovered ways to enjoy reading books along with nature by establishing bookshelves in mountains, forests, or green fields. These people have created libraries that place nature as the protagonist. In spatial terms, natural environments mainly encompass scientific and systemic concepts and embrace a sentimental approach to the natural environments of local areas not previously considered. The purpose of this research study is to present the direction for spatial planning that harmonizes nature with space, and to propose the spatial planning of a "small library" by applying natural environmental characteristics.

  • Background: Brain abscess is a life-threatening condition that occurs due to complications during a neurosurgical procedure, direct cranial trauma, or the presence of local or distal infection. Infection in the oral cavity can also be considered a source of brain abscess. Case presentation: A 45-year-old male patient was transported with brain abscess in the subcortical white matter. Navigation-guided abscess aspiration and drainage was performed in the right mid-frontal lobe, but the symptoms continued to worsen after the procedure. A panoramic radiograph showed alveolar bone resorption around the maxillary molars. The compromised maxillary molars were extracted under local anesthesia, and antibiotics were applied based on findings from bacterial culture. A brain MRI confirmed that the three brain abscesses in the frontal lobe were reduced in size, and the patient's symptoms began to improve after the extractions. Conclusion: This is a rare case report about multiple uncontrolled brain abscesses treated by removal of infection through the extraction of maxillary molars with odontogenic infection. Untreated odontogenic infection can also be considered a cause of brain abscess. Therefore, it is necessary to recognize the possibility that untreated odontogenic infection can lead to serious systemic inflammatory diseases such as brain abscess. Through a multidisciplinary approach to diagnosis and treatment, physicians should be encouraged to consider odontogenic infections as a potential cause of brain abscesses.

  • Issues related to the elderly have been recognized in Korea and nursing schalors have tried to study these issues. It is hard to say which the direction we, are going or have to go, since there has been little systemic effort to establish gerontological nursing field yet. Therefore, it is necessary to find out the trend and the guidelines of gerontolotical nursing studies for the future. Dissertation and published articles related to the elderly in the nursing field from 1991 to the Feburary of 1997 were are reviewed. Total 127 studies were analysed in terms of concept, design/methodology, and results, and the nature and issues of the gerontologic nursing studies in Korea were explored. The results are as follows : 1. There was no clear chronological definition of the elderly. 2. The most popular research design was an exploratory/descriptive study. 3. The major concepts studied were physical and mental health. 4. Among those studies using instruments which were developed and modified and/or translated by researchers, the reliability and validity were rarely reported. 5. Theory based studies were rare. We suggest the following issues for future studies : 1. The chronological and other criteria related to the defition of elderly is needed. 2. Physiopsychosocial characteristics of Korean elderly and their mangements in terms of intervention studies need to be conducted more systemically. 3. Social issues from the change of types and functions of family such as single elderly family need to be studied. 4. Participation in and collaborate with other disciplins are needed. 5. Development and test of instruments to measure phenomena or concepts is needed. 6. Macroscopic approach such as policy also needed. 7. Theory based studies are needed.

  • In fully edentulous cases, which are accompanied by severe residual ridge resorption and impairment of supporting tissues of complete dentures, proper diagnosis and systemic treatment planning are required for the improvement in retention, stability, and support of prosthesis. Provisional restoration, while it is unfamiliar in complete denture restoration, can be used as a valuable tool, which makes possible to evaluate the stability of complete dentures and receive feedback from patients in complex clinical situations. In this case, a provisional denture was used to improve stability of impression, polished, and occlusal surfaces of complete denture, and to consider esthetic requirements before final denture construction. The result was clinically satisfactory in terms of functional and esthetical aspects.

  • Ji-San, the founder of HyungSang medicine, emphasized food intake and detoxification by stating, "Korean medicine begins with detoxification." Toxin accumulates in one's body unless the internal and external conditions stay in their harmony. The accumulation of toxin is also caused by western medication or one-sided diet, and detoxification should be considered in those cases. HwangRyunHaeDok-Tang reduces fire and heat, and the lesion is likely to locate in the upper body. BangPoongTongSung-San can be used for systemic disease. IkWoon-San also reduces fire and heat but mainly focuses on promoting urination. InSamPaeDok-San has an effect of curing the external symptoms of SangHan(傷寒), in addition to detoxification. SeoGakJiHwang-Tang, SoDok-Eum, and SeoGakSoDok-Eum can resolve the heat-toxin when it is located on the surface. SibJeonDaeBo-Tang enhances the detoxifying function of human body. GhamDu-Tang and JaGeum-Jung have a general effect on detoxification.

  • Aims: To analyse the predictors of recurrence, disease free survival and overall survival in cases with endometrial cancer. Materials and Methods: A total of 152 women diagnosed with endometrial cancer were screened using a prospectively collected database including age, smoking history, menopausal status, body mass index, CA125, systemic disorders, tumor histology, tumor grade, lymphovascular space invasion, tumor diameter, cervical involvement, myometrial invasion, adnexal metastases, positive cytology, serosal involvement, other pelvic metastases, type of surgery, fertility sparing approach to assess their ability to predict recurrence, disease free survival and overall survival. Results: In ROC analyses tumor diameter was a significant predictor of recurrence (AUC:0.771, P<0.001). The optimal cut off value was 3.75 with 82% sensitivity and 63% specificity. In correlation analyses tumor grade (r=0.267, p=0.001), tumor diameter (r=0.297, p<0.001) and the serosal involvement (r=0.464, p<0.001) were found to significantly correlate with the recurrence. In Cox regression analyses when some different combinations of variables included in the model which are found to be significantly associated with the presence of recurrence, tumor diameter was found to be a significant confounder for disease free survival (OR=1.2(95 CI,1.016-1.394, P=0.031). On Cox regression for overall survival only serosal involvement was found to be a significant predictor (OR=20.8 (95 % CI 2.4-179.2, P=0.006). In univariate analysis of tumor diameter > 3.75 cm and the recurrence, there was 14 (21.9 %) cases with recurrence in group with high tumor diameter where as only 3 (3.4 %) cases group with smaller tumor size (Odds ratio:7.9 (95 %CI 2.2-28.9, p<0.001). Conclusions: Although most of the significantly correlated variables are part of the FIGO staging, tumor diameter was also found to be predictor for recurrence with higher values than generally accepted.

  • This paper reviews the most central analytical and methodological issues that arise in developing national STI strategies. First, an outline of the relationship between national innovation systems and the strategic dimension is presented. The paper shows that science, technology and innovation strategy are often used in different forms and that there is no common understanding yet of the actual meaning and coverage of these strategies. The paper develops the terminology from a discussion of different approaches towards company innovation processes analyzing their evolution in different socioeconomic environments and the role and impact of science, technology and innovation policy on company innovation processes. Based on this conceptual understanding the paper defines national science, technology, innovation, and STI strategy and explains the basic terminology. From these definitions, the strategic dimension including the impact on the stakeholders is discussed. It is shown that a major success factor for STI strategy development is the involvement of stakeholders to vary and extend their use of their portfolio of instruments. Moreover it becomes evident that stakeholders follow their own interests which aren't necessarily in the interest of the national STI strategies. The analysis shows advantages and disadvantages as well as potentials and limitations of different approaches to develop STI strategies in their ability to describe the reality of innovation processes and to allow conclusions about the relationship between innovation policy and the innovation processes implemented by companies. It is shown that knowledge of these limitations is an important factor to consider in designing consistent and coherent national STI policy which aims at supporting innovation eventually. Finally the paper concludes that the STI policy mix concept needs a more systemic development approach which is integrated in the national STI strategy development and implementation.

  • Inverted papilloma arising from mucous membrane of the nasal cavity and paranasal sinuses is very rare benign neoplasm. Ward first described nasal papilloma in 1854, but its infrequent occurrence has delayed accurate understanding. This tumor was histologically benign neoplasm and clinically malignant, because it is locally invasive with extensive bone erosion at times and it shows a high incidence of local recurrence, and change of squamous cell carinoma was sometimes found. Recently, the authors have experienced a case of inverted pailloma with focal squamous cell carcinoma change which occupied the right side of the nsal cavity and maxillary sinus in a 48-year-old male. The tumor mass was removed surgically through intranasal and Caldwell-Luc's approach, and then was treated with systemic administration of Bleomycin, local spray of 5-FU and radiotherapy ($Co^{60}$). We report our case with review of current literatures.
