This paper considers backing structure of non-contact steel plate using magnectically levitation and aspect-quality factor is defined by estimation of electromagnet-aspect attraction steel plate. Characteristics of attraction power is studied in cylindrical electromagnet, U-type electromagnet, E-type electromagnet by aspect-quality factor. Designing and manufacturing electromagnet attraction steel plate, propriety of experimental results is confirmed.

This paper proposes speed control system using a Fuzzy Logic Controller(FLC) in order to realize the speed control of Permanent Magnet AC Motor with no sensor. FLC based MRAS(Model Reference Adaptive System) estimates the speed of Permanent Magnet AC Motor. Using the estimated speed, speed control is performed. The experiment is executed to verify the propriety and the effectiveness of the proposed system.

In this paper, we develop the Jeffreys' prior, reference prior and the the probability matching priors for the difference of intraclass correlation coefficients in familial data. e prove the sufficient condition for propriety of posterior distributions. Using marginal posterior distributions under those noninformative priors, we compare posterior quantiles and frequentist coverage probability.

It is very necessary to adopt bad data processing in order to maintain the security and the reliability of data acquisition and management in the substation. This paper presents a bad data processing method of per module unit by using rule based system. The propriety of this method has been verified by the case study

Consider the problem of estimating the system reliability using noninformative priors when both stress and strength follow generalized gamma distributions. We first treat the orthogonal reparametrization and then, using this reparametrization, derive Jeffreys'prior, reference prior, and matching priors. We next provide the suffcient condition for propriety of posterior distributions under those noninformative priors. Finally, we provide and compare estimated values of the system reliability based on the simulated values of the parameter of interest in some special cases.

여러 관광자원 중에서도 동굴은 지하에 분포하고 있기 때문에 특이하며, 일반 관광자원보다 사람들에게 관심이 높고 견인력이 큰 자원이어서. 최근들어 동굴은 레크리에이션 장소로도 각광받고 있다. 이런 특성을 지닌 동굴 중에서 강원도 영월군 서면에 위치한 동정굴은 도로상에 입지하고 있으며, 부근에 자연풍치자원 이외에도 사적자원, 산업자원 등이 산재하고 있어 관광 개발에 유리한 입지로 판단된다. 특히 평창강의 심한 곡류, 우뚝 솟은 하식애 등의 하천지형과 지표면의 카르스트 지형 및 동굴 내부의 2차 생성물들은 동정굴을 지형지물의 전시장이며 자연학습의 현장이라는 특성을 지닌 관광지로 개발할 수 있는 전망을 제시하고 있다. 따라서 동정굴 지역을 주변의 각종 관광자원을 유기적으로 연결시키는 역할을 담당하도록 개발해야 하겠다.

삼척군 하장면에 있는 월둔굴은 지방기념물로 지정된 석회동굴이다. 이 동굴은 강원도 내륙지역에 해당되고 있으나, 내륙인 정선에서 동해안의 삼척에 이르는 내륙교통의 요지에 위치하고 있고, 그 동굴 속의 2차 생성물들의 학술적ㆍ관광적 가치도 크기 때문에 관광지 개발에 합당한 동굴이라고 판단된다. 더구나 이 곳 현지주민들의 인문ㆍ산업 면에서 볼 때에도 산간오지의 밭농사에 의존할 수밖에 없어 이 동굴의 개발이 지역주민의 소득증대에도 이바지할 수 있을 것으로 판단된다.

Meta-evaluation for national R&D programs should be established within the framework of whole R&D system linked with science and technology needs and objectives. The R&D program evaluation system can be understood as a circulation of input, implementation, output, and utilization. In the result of the Delphi survey, which consisted of twenty-four experts (performed in three rounds), twenty-four indices were developed. The meta-evaluation model included sub-items which were important points of view of it as follow (eight items): propriety of planning, sufficiency of information, and propriety of evaluators in evaluation input; appropriateness of method and appropriateness of procedure in evaluation implementation; credibility of output in evaluation output; and usefulness of report and application of evaluation utilization. As the application of the meta-evaluation model, the total mean was lower than 3.0 of the median value of 2.73 (5 point Likert scale). Finally, it was suggested that the feedback of evaluation results should be more enforced to R&D program improvement particularly (evaluation utilization 2.50).

In this paper, an experimental study have been many studies on the joints of steel structure, for it has great influences on the safety of structures. Research on block shear rupture of the joint receiving pure tension have been done in foreign countries, but not in Korea. This study focuses on the propriety of block shear design code, according to limited state design criteria of steel structures recently established in Korea, by an experiment on the joint of angle tension members. The methods of this study were to compare other study results on block shear rupture mode and ultimate capacity, and to evaluate the propriety of the criteria design code. The result is that tension yield shear ruptures and shear yield tension ruptures happened at the joint, and the experimental rupture load was 15% higher than the capacity entered in the criteria design code. We conclude that it is necessary to revaluate the block shear design code presented by many studies on the limited state design criteria of steel structures.

Recently, percentage of people who use SMS service is increasing. However, it is difficult to express own complicated emotion with text and emoticon of exited SMS service. This paper focuses on that point and practical uses character animation to express emotion and nuance correctly, funny. Also this paper suggests emotion based gesture animation generation system that use character's facial expression and gesture to delivery emotion excitably and clearly than only speaking. Michel[1] investigated interview movies of a person whose gesturing style they wish to animate and suggested gesture generation graph for stylized gesture animation. In this paper, we make focus to analyze and abstracted emotional gestures of Disney animation characters and did 3D modeling of these emotional gestures expanding Michel[1]'s research. To express emotion of person, suggests a emotion gesture generation graph that reflects emotion flow graph express emotion flow for probability. We investigated user reaction for research the propriety of suggested system and alternation propriety.
