Periodontal disease accompany the inflammation around periodontal tissue and generally periodontal destruction is followed, This destruction often makes the molar teeth have furcation defect. And to treat molar furcation involvement, resective surgery such as root resection and ostectomy and regenerative procedure such as guided tissue regeneration were introduced. Also implant can be considered as one of the good treatment methods, Among these treatment alternatives, root resection can be considered as a good procedure in the point of saving one's natural teeth or amount of cost. Therefore the purpose of this article is to evaluate root-resected teeth which were done at least 2 years ago. 70 root-resected teeth in 58 patient who visited Kyungpook National University Hospital were included in this study. They were evaluated by two clinical method. One is subjective evaluation and another is objective evaluation. To evaluate subjective outcome, 58 patients answered to the questionnaire if they experienced tooth extraction, bleeding, swelling, pain, mobility and chewing problem. To evaluate objective outcome, 28 teeth was evaluated according to Langer's criteria. The subjective result showed 82% of success rate and 18% of failure rate. 13 of 70 teeth showed discomfort and were considered as failure, which include chewing problem (39%) and pain (23%). The objective outcome showed that 4 failure (14% failure rate) which were 2 cases of bone loss by periodontal problem, one endodontic problem and one untreatable caries. By these limited results, some of clinical consideration in root resective procedure can be suggested. Periodontal support and less occlusal loading on resected tooth should be evaluated before the procedure, moreover, good oral hygiene is essential. When these factors are considered carefully, the root resection may produce predictive outcomes in the treatment of furcational involvement.

As the evaluation for the information security has been an important issue, numerous security evaluation methods have been proposed. Those security evaluation methods can be categorized into three different aspects in large including product, process and control. In this paper we identify the possible problems that may occur when one-sided security evaluation is conducted that is on the aspect of product, process or control alone, present with the actual example of threat, and propose an approach to resolve each problem. Based on these approaches, we propose the security evaluation model, which incorporates these three aspects of product, process and control.

Recently, the frequency of typhoon and torrential rain due to climate change is increasing. In addition, the upsurge in the complexity of urban sewer network and impervious surfaces area aggravates the inland flooding damage. In response to these worsening situations, the central and local governments are conducting R&D tasks related to predict and mitigate the flood risk. Researches on the analysis of inundation in urban areas have been implemented through various ways, and the common features were to evaluate the accuracy and justification of the model by comparing the model results with the actual inundation data. However, the evaluation procesure using available urban flooding data are not consistent, and if there are no quantitative urban inundation data, verification has to be performed by using press releases, public complaints, or photos of inundation occurring through 'CCTV'. Because theses materials are not quantitative, there is a problem of low reliability. Therefore, this study intends to develop a comparative analysis procedure on the quantitative degree and applicability of the verifiable inundation data, and a systematic framework for the performance assessment of urban flood analysis model was proposed. This would contribute to the standardization of the evaluation and verification procedure for urban flooding modelling.
