The purpose of this research is to analysis of distinction according to athletics class teaching of sport activities participation by primary school female teachers. The result showed that primary school female teachers who had participated in sports activities had higher average in athletic class recognition and athletic class teaching than those who had not participated in sports activities. The difference was statistically significant. Among participators to sports activities, teachers who participated in "indirect competition type sports" had higher average in athletic class teaching than those who had participated in "performance record type sports" or "aesthetic sports". The difference was statistically significant. Regarding degree of participation in sports activities, teachers who had participated in twice and more than twice a week had higher average in athletic class teaching than those who had participated in once or less than once a week. The difference was statistically significant. There was no significant difference among groups regarding participating time or participating period in sports activities. In conclusion, our research suggests that sports activities participation by primary school female teachers gives positive impact to athletic class teaching.

Among the techniques to protect private information by adopting biometrics, speaker verification is expected to be widely used due to advantages in convenient usage and implementation cost. Speaker verification should achieve a high degree of the reliability in the verification score, the flexibility in speech text usage, and the efficiency in verification system complexity. Continuants have excellent speaker-discriminant power and the modest number of phonemes in the category, and multilayer perceptrons (MLPs) have superior recognition ability and fast operation speed. In consequence, the two provide viable ways for speaker verification system to obtain the above properties. This paper implements a system to which continuants and MLPs are applied, and evaluates the system using a Korean speech database. The results of the experiment prove that continuants and MLPs enable the system to acquire the three properties.

This study analyzed the effect of female insurance planners' personal traits on job performance in Dangjin, Chungnam. The study results showed that job importance recognition(p<.05, ${\beta}=.321$) significantly affected job satisfaction, so highly recognizing the importance and social reputation improved job satisfaction. Personal traits didn't significantly affected contract performace and workplace satisfaction, but job performance varied by continuos service year. This study provided implications by finding out the degree of importance of personal traits on job performance improvement and verifying the effect of personal factors on performace enhancement of female insurance planners.

The main goal of this paper is to introduce a novel definition for fuzzy mathematical morphology and a neural network implementation. The generalized- mean operator plays the key role for the definition. Such definition is well suited for neural network implementation. The first stage of the shared-weight neural network has adequate architecture to perform morphological operation. The shared- weight network performs classification based on the features extracted with the fuzzy morphological operation defined in this paper. Therefore, the parameters for the fuzzy definition can be optimized using neural network learning paradigm. Learning rules for the structuring elements, degree of membership, and weighting factors are precisely described. In application to handwritten digit recognition problem, the fuzzy morphological shared-weight neural network produced the results which are comparable to the state-of art for this problem.

The purpose of this study is to understand the cognitive power from user who have used hotel management information system and to search contribution level for hotel management. The survey results are : There are different cognitions, between PKG and developed user system, short term employee and long term employee, reservation part and front office part. Specially IT service management parts(mostly outsourcing) have low degree cognition, because of lated supporting and being short of IT service management system. Hotel information system construction gives us to be easy management operating and to be fast management but Hotel information system has to lead value creation, to support decision making, to present advavced management for hotel.

The most fundamental difference between general three dimensional computer graphics technology and virtual reality technology lies in the degree of realism as we feel, and thus the virtual reality method heavily relies on such tolls as data gloves, 3D auditory system to enhance human perception and recognition. Although these tolls are valid for such purpose, more essential ingredient. This paper provides further realism by modeling active interactions between the objects inside scenes. For this purpose, this paper proposes and implements a field model where the virtual reality space is treated as a physical field defined on the characteristic radius of stimulus and sense corresponding to the individual object. In the field model, the rule of cause and effect as an essential feature of the realism can be interpreted simply as an energy exchange between objects and consequently, variation on the radius information together with behavioral logic alone can build the virtual environment where each object can react to other objects actively and controllably.

Color therapy is a diagnostic method for treating psychological problems using unique vibration and frequency color. The color has strong subjective psychology, it can give psychological stabilization effect as a spring as a favorite color and stability become personally personal. Also, to give various influences on emotion, we can obtain information via brain wave to evaluate these emotions. In this research, before viewing two kinds of VR color images of red and blue, responding to the stress questionnaire(BEPSI-K) via a mobile terminal. At this time, we analyzed the real-time we used four emotional data measurable via brain waves and grasped the user's emotional state. In addition, the stress questionnaire was used to quantify the emotion degree, and comparative analysis was made on how the color image affects the change of emotions with 3D virtual reality.

In this paper We measured average earnings differentials between the government and the private sector, the degree of earnings inequality within each sector, and estimated net earnings differentials between the public and private sector in 1982, 1985, 1990, 1995 and 1998, respectively. According to our estimation results, the public servants in Korea are being more paid than the private sector on the average, and have been enjoying higher net wage premium after controlling variables such as education level, job experience and occupation, etc. In terms of earning inequality within each sector, the public sector was proven to have very narrow earnings differentials between the top and the bottom, compared to quite large differentials in the private sector. Wide recognition that the public servants' compensation is lower in Korea seems quite wrong. The problem to be resolved is the earnings standardization in the public sector and the strong trend toward more equality in recent years. We recommend that the wage gap between the higher rank and the lower rank should be extended, and employment flexibility within the lower positions or ranks of the bureaucracy should be enhanced.

Pre-emphasizing the speech compensates for falloff at high frequencies. The most common form of pre-emphasis is y(n)=s(n)-A${\cdot}$s(n-1), where A typically lies between 0.9 and 1.0 in voiced signal. And, this value reflects the degree of pre-emphasis and equals R(1)/R(0) in conventional method. This paper proposes a new flattening method to compensate the weaked high frequency components that occur by vocal cord characteristic. We used QMF(Quardrature Mirror Filter) to minimize the output signal distortion. After using the QMF to compensate high frequency components, flattening process is followed by R(1)/R(0) at each frame. Experimental results show that the proposed method flattened the weaked high frequency components effectively than auto correlation method. Therefore, the flattening algorithm will apply in speech signal processing like speech recognition, speech analysis and synthesis.
