Sedation or general anesthesia is often required to offer dental treatment to patients with special needs. However, patients with ASA classification of III or higher are not indicated for moderate sedation and might be exposed to danger when treated at outpatient dental clinic. For this reason, it is recommended to treat those patients under general anesthesia. The dental team can supervise and monitor the whole procedures during treatment with an appropriately equipped facility. This case report describes the dental treatment of a 7-year-old girl with multiple disabilities. Preoperative evaluation including medical consultation was carried out thoroughly and dental treatment was performed under general anesthesia safely.

The pre-treatment for conservation must be needed for the exhumed historic sites. So, the study of conservation and restoration of historical sites has progressed favorably with using various polymers for solving upper problems. The problems which should be essentially solved for conservation of the exhumed historic sites are, however, using reinforcing agents that don't impair their original forms and sorting reinforcing agents on the lines of the historic sites' soil. These agents should be able to use without the effect of outer environments like marsh, winter time or temperature. In this work, we synthesized Epoxy resin and Epoxy hardener for the restoration of historical sites. These products have very good tension strength and adhesion strength and various physical properties that the users want. Particularly, these epoxy with high viscosity have good separation of between Epoxy final product and Urethane pre-surface.

영상은 동적인 시각 이미지와 청각의 결합에 의해 감성적인 반응을 유도한다. 다양한 영상 기법을 통하여 감성적 반응의 극대화를 추구하는 영화는 영상의 시청각적 요소들을 감성의 관점에서 효과적으로 설계하는데 본보기가 된다. 그러나, 제품의 설계속성들에 대한 감성적 평가결과를 모형화하는 감성공학적 관점에서 볼 때 영화는 시청각적 자극의 수준이 극히 다양하고 동적인 경험재로 모형화의 어려움이 있다. 본 연구에서는 영화의 감성 모형을 구축하기 위한 사전연구의 단계로 영화에서의 시청각적 요인들을 문헌조사를 통해 수집, 정리, 선별하고 이러한 시청각적 요인들 중에 영화를 관람하는 관객의 감성적, 인지적 반응에 영향을 주는 유효한 요인들을 객관적이고 체계적으로 탐색하고자 하였다. 이를 위해, 감성 및 인지적 반응의 변화를 생체신호를 통해 측정하는 한편, 생체신호의 측정 시 사용된 영화의 시청각적 자극요인을 Video/Audio Processing방법에 의해 연속적인 수치로 정량화하였다. 생체신호와 정량화된 시청각적 자극요인을 동기화하고 통계적으로 분석함으로써, 생체신호의 반응과 시청각적 자극요인과의 인과관계를 통계적으로 신뢰성있는 수준에서 검증하고자 하였다. 생체신호를 종속변수로, 시청각적 자극요인을 독립변수로 하는 896개의 부분선형회귀모형(Partial Linear Regression Model)들 중 통계적으로 유의한 선형관계에 있는 경우의 빈도분석에 의하면, 시각적 요인들 중에는 밝기(Brightness), 대비(Contrast), 색상(Color), 움직임(Motion), 장면전환속도(Shot change Rate), 주요대상의 상대적 크기가, 청각적 요인들 중에는 Peak주파수, Peak주파수의 음량, 평균음량, 소음비(Sound-to-Noise Ratio)가 생체신호의 변화에 통계적으로 유의한 영향을 주는 것으로 나타났다. 이는, 위의 시청각적 자극 요인들은 특히 관객의 감성 및 인지적인 반응에 유의한 영향을 주는 요소로 작용할 수 있음을 시사하고 있다. 이를 토대로, 위의 시청각적 자극 요인들이 가지는 다양한 조합들을 설명변수로 하는 통계적인 영화의 감성 모형을 구축할 수 있을 것으로 기대한다.

This Paper Proposes a new optimization algorithm named by GBNSGA-II(Goal-pareto Based Non-dominated Sorting Genetic Algorithm-II) which uses Goal Programming to find non-dominated solutions in NSGA-II. Although the conventional NSGA is very popular to solve multiobjective optimization problem, its high computational complexity, lack of elitism and difficulty of selecting sharing parameter have been considered as problems to be overcome. To overcome these problems, NSGA-II has been introduced as the alternative for multiobjective optimization algorithm preventing aforementioned defects arising in the conventional NSGA. Together with advantageous features of NSGA-II, this paper proposes rather effective optimization algorithm formulated by purposely combining NSGA-II algorithm with GP (Goal Programming) subject to satisfying multiple objectives as possible as it can. By conducting computer simulations, the superiority of the proposed GBNSGA-II algorithm will be verified in the aspects of the effectiveness on optimization process in presence of a priori constrained goals and its fast converging capability.

High-speed weigh in motion (HS-WIM) is a real-time unmanned system for measuring the weight of a freight-carrying vehicle while it is in motion without controlling vehicle traffic flow or deceleration. In Korea, HS-WIM systems are installed on the national highways and general national ways for pre-selection by law enforcement. In this study, to improve the measurement accuracy of HS-WIM, we devise improvements to the existing integral and peak weight conversion algorithms, and we provide a new fusion algorithm that can be applied to the mat-type HS-WIM. As a result of analyzing vehicle driving tests at a real site, we confirmed the highest level of weight-measuring accuracy.

This paper suggests several methods of improving information securities of universities through the investigations of the current status of information securities in universities, which is becoming a hot topic in knowledge and information societies. In this paper, universities were randomly selected according to their size, and surveyed through email questionnaire to the persons in charge of security in each university, and 27 universities and 18 colleges were replied. From the survey results we confirmed that the pre-prevention is the most important thing in securing information assets, also in universities, and, in this paper, systematic support must be strengthened to establish a comprehensive security management policy and guidelines for the universities, and the importance of information assets and the necessity of security needs to be shared with the members in the universities. Moreover there must be full administrative and financial support, including recruitment and training of information security professionals and the establishing a separate security division.

This paper presents chunking strategy of a contiguous nouns sequence using semantic class. We call contiguous nouns which can be treated like a noun the compound noun phrase. We use noun pairs extracted from a syntactic tagged corpus and their semantic class pairs for chunking of the compound noun phrase. For reliability, these noun pairs and semantic classes are built from a syntactic tagged corpus and detailed dictionary in the Sejong corpus. The compound noun phrase of arbitrary length can also be chunked by these information. The 38,940 pairs of 'left noun - right noun', 65,629 pairs of 'left noun - semantic class of right noun', 46,094 pairs of 'semantic class of left noun - right noun', and 45,243 pairs of 'semantic class of left noun - semantic class of right noun' are used for compound noun phrase chunking. The test data are untrained 1,000 sentences with contiguous nouns of length more than 2randomly selected from Sejong morphological tagged corpus. Our experimental result is 86.89% precision, 80.48% recall, and 83.56% f-measure.
