This experiment was conducted to determine the influence of litter type on growing performance of broiler and litter characteristics. Sawdust, wood chips and solid part of cattle manure was used as a litter from 7 to 42 days of broiler age. The body weight was significantly (p<.05) higher in manure solid than those of sawdust and wood chips. The litter production was 2,134, 2,246 and 1,785g per bird on the sawdust, the wood chip and the manure solid during 35 days, respectively. Although the initial moisture contents of the litter materials were different 23.5% for sawdust, 16.26% for wood chips and 61.57% for cattle manure solids, the moisture were different 23.5% for sawdust, 16.26% for wood chips and 61.57% for cattle manure solid, the moisture contents became similar after 28 days of the experimental period. The nitrogen content of manure solid was higher than those of sawdust and wood chips. It was concluded that solid part of cattle manure and wood chips were potentially useful source of litter materials for broiler.

The goals of the present study were (3) to collect and analyze sets of fundamental frequency (F0) and formant frequency (F1, F2, F3) data of Korean diphthongs from ten linguistically homogeneous speakers of Korean males, and (2) to make a comparative study of Korean monophthongs and diphthongs. Various definitions, kinds, and previous studies of diphthongs were examined in the introduction. Procedures for screening subjects to form a linguistically homogeneous group, time point selection and formant determination were explained in the following section. The principal findings were as follows: 1. Much variation was observed in the ongliding part of diphthongs. 2. F2 values of (j) group descended while those of [w] group ascended, 3. The average duration of diphthongs were about 110 msec, and there was not much variation between speakers and diphthongs. 4. In a comparative study of monophthongs and diphthongs, Fl and F2 values of the same offgliding part at the third time point almost converged. 5. The gliding of diphthongs was very short beginning from the h-noise. Perceptual studies using speech synthesis are desirable to find major parameters for diphthongs. The results of the present study wi11 be useful in the area of automated speech recognition and computer synthesis of speech.

Most stochastic taggers can not resolve some morphological ambiguities that can be resolved only by referring to lexical contexts because they use only contextual probabilities based ontag n-grams and lexical probabilities. Existing lexical rules are effective for resolving such ambiguitiesbecause they can refer to lexical contexts. However, they have two limitations. One is that humanexperts tend to make erroneous rules because they are deterministic rules. Another is that it is hardand time-consuming to acquire rules because they should be manually acquired. In this paper, wepropose context-dependent lexical rules, which are lexical rules based on the statistics of a taggedcorpus, and an ambiguity-driven teaming method, which is the method of automatically acquiring theproposed rules from a tagged corpus. By using the proposed rules, the proposed tagger can partiallyannotate an unseen corpus with high accuracy because it is a kind of memorizing tagger that canannotate a training corpus with 100% accuracy. So, the proposed tagger is useful to improve theaccuracy of a stochastic tagger. And also, it is effectively used for detecting and correcting taggingerrors in a manually tagged corpus. Moreover, the experimental results show that the proposed methodis also effective for English part-of-speech tagging.

This paper presents a novel design for a tubular linear brushless permanent-magnet motor. In this design, the magnets in the moving part are oriented in an NS-NS―SN-SN fashion which leads to higher magnetic force near the like-pole region. An analytical methodology to calculate the motor force and to size the actuator was developed. The linear motor is operated in conjunction with a position sensor, three power amplifiers, and a controller to form a complete solution for controlled precision actuation. Real-time digital controllers enhanced the dynamic performance of the motor, and gain scheduling reduced the effects of a nonlinear dead band. In its current state, the motor has a rise time of 30 ms, a settling time of 60 ms, and 25% overshoot to a 5-mm step command. The motor has a maximum speed of 1.5 m/s and acceleration up to 10 g. It has a 10-cm travel range and 26-N maximum pull-out force. The compact size of the motor suggests it could be used in robotic applications requiring moderate force and precision, such as robotic-gripper positioning or actuation. The moving part of the motor can extend significantly beyond its fixed support base. This reaching ability makes it useful in applications requiring a small, direct-drive actuator, which is required to extend into a spatially constrained environment.

Recent three-dimensional feature-based CAD systems based on solid or non-manifold modelling functionality have been widely used for product design in manufacturing companies. When product models associated with features are used in various downstream applications such as analysis, however, simplified and abstracted models at various levels of detail (LODs) are frequently more desirable and useful than the full detailed model. To provide multi-resolution models, the features need to be rearranged according to a criterion that measures the significance of the feature. However, if the features are rearranged, the resulting shape is possibly different from the original because union and subtraction Boolean operations are not commutative. To solve this problem, in this paper, the new concept of the effective zone of a feature is defined and identified using Boolean algebra. By introducing the effective zone, an arbitrary rearrangement of features becomes possible and arbitrary LOD criteria may be selected to suit various applications. Besides, because the effective zone of a feature is independent of the data structure of the model, the multi-resolution modelling algorithm based on the effective zone can be implemented on any 3D CAD system based on conventional solid representations as well as non-manifold topological (NMT) representations.

Ganglion cysts are most common on the dorsum of the hand or wrist, but they can occur in any part of the body. There have been few papers reporting ganglion cysts originating from the sternoclavicular joint, with most of these cases developing in children. A 76-year-old woman was referred to our department because of a painless mass over the right sternoclavicular joint. The mass was excised along with the portion of the sternoclavicular joint capsule surrounding the stalk. Histopathologic examination showed the cyst wall to be composed of compressed collagen fibers without evidence of an epithelial or synovial lining, which was consistent with ganglion cyst. To our knowledge, this is the first report of such a cyst in an adult. We consider this to be a useful report for surgeons that treat mass lesions occurring in almost any part of the body surface.

The purpose of this research is to analyze the formational process of traditional house in old village that is the base of development on rural area. The method of this research is to use the family genealogy of the clan society village in the analysis of building times, and constructed with investigation by the residents. The results of this research are described as follows. 1. At the first period of settlement in the middle time of 18C, the small relative family was located at nearby of each other. They were divided three group. The first entered man is B-group. 2. At the period of 19C, the family was enlarged by the descendants. But at that time, the house was constructed by small type. And some tiled roof houses were built by A-group part at under area of the village. And the construction of village boundary was nearly completed. 3. At the early period of 20C, the great houses were constructed by C-group part at the upper area of the village. 4. At the late period of 20C, there were not changed largely. But small change was occurred by the divided of site. Except two house, every houses were changed to tiled roof house. The residents have continued the strong preservation mind of environment for 300 years. The family genealogy was very useful to analyze the formational process of traditional house in the clan society village.
