We used SAS program in statistics class as a plan to increase effect of class. Because lease cost of SAS program is high and low-level students felt difficulty of the syntax of SAS program, I planned to introduce other instruction-software. We observe whether it's O.K. to use Excel instead of SAS program and Excel is helpful in having positive attitudes. We try to compare and analyze the merits of two programs. The purpose of this study is to apply Excel to statistics class, cut down the cost of instruction-software, and make students understand statistics more conveniently and easily.

This presentation aims to explore some possibility of non-segmental phonetics usually ignored in phonetics education. In pedagogical phonetics, especially ESL/EFL oriented phonetics speech sounds tend to be classified in two criteria 1) 'pronunciation' which deals with segments and 2) 'prosody' or 'suprasegmentals', a criterion that deals with non-segmental elements such as stress and intonation. However, speech involves more dynamic processing. It is non-linear and multi-dimensional in spite of the linear sequence of symbols in phonetic/phonological transcriptions. No word is without pitch or voice quality apart from segmental characteristics whether it is spoken in isolation or cut out from continuous speech. This simply tells the dichotomy of pronunciation and prosody is merely a useful convention. There exists some room to consider dynamic non-segmental phonetics. Examples of non-segmental phonetic investigation, some of the analyses conducted within the frame of Firthian Prosodic Analysis, especially of the relation between vowel variants and foot types, are examined and we see what kind of auditory phonetic training is required to understand impressionistic transcriptions which lie behind the non-segmental phonetics.

The purpose of this study is to establish a clear-cut concept and meaning of soundscape design through an inquiry into the various literatures on the ideologies, features and domains of soundscape design. Soundscape enables us to design various relationship through a sound in that it is important for interaction, namely the relations with sound, environment and people in a region. Soundscape design is an endogenous design which is participated in a large number of people of the region, and it contains various activities such as research study, environmental preservation, creation of sound environment and sound education.

1. In the late second century A.D. the dalmatic, which originated in Orient, came into fashion in the Roman world. 2. It was first introduced as a vestment in public worship by Pope Sylvester I (314-335A.D.) who ordered it to be worn by the deacons. 3. The dalmatic was cut like a tunic, but wider, and with wide short sleeves. It was worn without belt, and was characteristically decorated by the clavus. Its shape, which is the form of a cross, refer to the passion of Christ. It symbolizes joy, salvation and justice. 4. In early christian epoch, colors was found in the Bible. 5. Clavus running from the shoulders to the hem in front and back represented as 'The servant of God', and symbolized the Blood of Christ. With time, clavi change from simple stripes to decorative ones.

With the advent of the internet era, web-based virtual training system is gaining its importance in recent years. Because of the fact that the training can take place in any place and at any time, the virtual system is now replacing many of the conventional off-line classes. Hardware environments such as communication bandwidth and computer performance gets fast enough to accommodate the virtual education. Based on the observations on current virtual training system, this paper proposes three critical design rules required when developing a new virtual training system: i) With conceptual mapping, the menu hierarchy can be organized in a clear-cut manner, ii) Extensive use of multimedia tools can help students keep their attention to the lecture materials, and iii) Provision of interaction mechanisms helps students to gain their identity and motivation.

The general manufacturing problem can be described as the achievement of a predefined product quality with given equipment, cost and time constraints. Unfortunately, for some quality characteristics of a product such as surface roughness it is hard to ensure that these requirements will be met. Stainless steels STS 304 is frequently used as shaft materials in small fiber reinforced polymer(FRP) fishing boats. In this work, the dry turning parameters of STS 304 are optimized by using Taguchi method. The experiments were conducted at three different cutting speeds with three different feed and three different depth of cut. The cutting parameters are optimized using signal to noise ratio and the analysis of variance. The effects of cutting speed and feed on surface roughness was analyzed. The results revealed that the spindle speed is the more significant parameter influencing the surface roughness.

The present study surveyed both the parents of 130 children with psychopathology and the parents of 240 normal children. children were between 2 and 12 years of age. No differences were found between parents in self-differentiation or in family function by type of disorder. Parents of children with psychopathology were lower than parents of normal children in self-differentiation; this was particularly evident in cognitive function-emotional function, and emotional cut-off. Patents of children with psychopathology were lower than parents of normal children in terms of family function. Multiple regression analyses indicated that parent's self-differentiation, children's psychopathology, and parent's education level had a significant influence on family function. The regression model explained 52% of the variance.

Since Korea opened the door to the Western World, traditional costume has changed. The factors of change are as follows: 1) Cultural diffusion by the cultural contact is the foundamental factor of the costume change. 2) The government made edicts of clothing reform. The formal dresses of government official were simplified several times, the edict was issued for men to cut off their hair, and military uniform and government officials' dresses were west-ernized. 3) The diffusion of modernized education by the missionary school accerlerated clothing change. Students were ahead of the abolition of Suege-Chima (which is a sort of veil used to conceal woman's face). 4) The change in the activity of women in society made the women's dresses more convenient for action. 5) The open class system and social agitation speeded up the rate of change. During the Yi Dynasty class distinction was rigid, but the government made the laws which abolished the class distiction.

A workflow is a flow of work carried out by multiple people. In order to increase efficiency, it is re-quired to change the current workflow dynamically. Till now, three types of dynamic changes: flush, abort, and synthetic cut-over (SCO) , have been proposed. How- ever, the performance evaluations for dynamic workflow changes have not been undertaken. To do so, measuring the amount of time cost making a single change (called change time) and comparing the methods for obtaining such times become ever important. In this paper, we first define change time and then propose a computation method individually for each change type. Finally, we evaluate the performance of an example net change by computing the change times.

This study is to analyze the kinematic variables in release motion of discuss throwing. For the matter, 5 people from the national team and collegiate discuss throwing in the year 2001 were chosen as the subjects and two S-VHS video cameras set in 60frames/sec were used for recording their motions. Coordinated raw positions data through digitizing are smoothing by butter-worth 's low-pass filtering method at a cut off frequency 6.0Hz. and the direct linear transformation(DLT) method was employed to obtain 3-D position coordinates. The conclusions were as follows; 1. The better record players showed the shorter approach time in the last support phase. 2. In the displacement CG, the better record players showed the shorter displacement in medial-lateral direction, and the longer displacement in horizontal direction. In the motion, the COG showed longer displacement vertical direction. 3. The better record players showed the faster horizontal velocity than vertical velocity in the release. 4. The better record players showed to take the posture of vertical axis in the release.
