  • Nowadays the use of computer has a tendency to be being increased in classroom. Also, Many mathematics teachers are attempting to use computer efficiently in classroom. Computer has unique functions such as graphic, animation, and error correction. As graphic and animation can make the content of mathematics visible and make it easy for learners to study mathematics, it is desirable to develop the computer educational program and use it in teaching and learning mathematics. Especially, before concepts study on the unit of Figure or Function, the use of graphic or animation is efficient by being able to understand easily the content. The purpose of this thesis is to produce the computer program on the Movement of Figure in the unit of Equation of Figure which is in mathematics curriculum for the first grade of high school. In teaching and learning mathematics by use of this program, the educational effects are expected as follows: 1. It is expected that this program will stimulate the interest of learners by using animation and acoustic (sound) effect and so learners' voluntary and active thinking activity will be shown. 2. It will be helpful to form exact concept because it is possible to understand intuitively the basic concepts on the Movement of Figure by using graphic and animation. 3. It is expected that the repeated study of this program already designed will remove the fear of incomplete parts and help review them. 4. It is possible to change from teacher-centered instruction, which is the blind point of recent mathematics education, to the learner-centered instruction. However, it is necessary to realize that using the educational engineering (computer) in mathematics education cannot always cause learners to study mathematics very well and that computer cannot take the place of mathematics teacher. Accordingly, computer will be treated as aids which help learners study difficult part.

  • Anticipatory postural adjustments is an example of the ability of the central nervous system to predict the consequence of the mechanical effect of movement on posture and helps minimize a forth coming disturbance. The aim of this study was to evaluate the sequence of activation of the trunk muscles during the performance of hip and shoulder movement and to determine the relationship between anticipatory activity and subjects' motor and functional status in subjects with hemiplegia post stroke. Twenty-four poststroke hemiparetic patients enrolled in this study. Electromyographic activity of the lumbar erector spinae, latissimus dorsi, and of the obliquus internus muscles was recorded bilaterally during flexion of both arm and from the rectus abdominis, obliquus externus, and obliquus internus muscles during flexion of both hip. Onset latencies of trunk muscles were partially delayed in the subjects with hemiplegia post stroke (p<.05). With upper limb flexion, the onset of erector spinae muscle and latissimus dorsi muscle activity preceded the onset of deltoid on both side respectively (p<.05). A similar sequence of activation occurred with lower limb flexion. Also the onset of external oblique muscle and rectus abdominis muscle activity preceded the onset of rectus femoris muscle on both side (p<.05). Major impairments in the activity of trunk muscles in hemiparetic subjects were manifested in delayed onset between activation of pertinent muscular pairs. These problems were associated with motor and functional deficits and warrant specific consideration during physical rehabilitation of post stroke hemiparetic patients.

  • The purpose of the current experiment was to describe interlimb coordination when swing limb conditions are being manipulated by constraining step length or by adding a 5 or 10 pound weight to the swing limb distally. Subjects were asked to begin walking with the right limb to land on the primary target (normal step length) that is 10 cm in diameter. However, if, during movement, the light was illuminated, then the subject had to step on one of the secondary targets (long and short step length). These three step length conditions were repeated while wearing a 5 pound ankle weight and then when wearing a 10 pound ankle weight. Ground reaction force (GRF) data indicated that there were changes in the forces and slopes of the swing and stance Fx GRFs. Long stepping subjects had to increase the propulsive force required to increase step length. Consequently, swing and stance toe-off greatly increased in the long step length condition. Short step length subjects had to adequately adjust step length, which decreased the speed of gait initiation. Loading the swing limb decreased the force and slope of the swing limb. Swing and stance toe-off was longest for the long step length condition, but there was a small difference of temporal events between no weight and weight condition. It appears that subjects modulated GRFs and temporal events differently to achieve the peak acceleration force of the swing and stance limb in response to different tasks. The findings from the current study provide preliminary data, which can be used to further investigate how we modulate forces during voluntary movement from a quiet stance. This information may be important if we are to use this or a similar task to evaluate gait patterns of the elderly and patient populations.

  • This study reviewed both consumer movement and consumer policy of government in Japan. Their evolution since the Second World War will be reviewed and compared multiple periods, after the Second World war till the late 1960s, the period of the 1970s, the period after 1980s. In addition, firms' consumer satisfaction policies were briefly reviewed in order to fully understand consumer protection activities in japan. This study found four major characteristics of consumer protection activities led by both voluntary consumer organizations and government. First, consumer protection policy of government in Japan after the late 1960s was more active than that of consumer movement by consumer organizations. Second, major concerns for consumer protection were variant over time. The major goal in the first stage of period(during the 1960s) was to protect consumer safety from defective and dangerous goods and services, whereas the goal after the late 1970s was extended to cover various areas concerning the quality of life. Those areas refer to the quality of services, the way of sales and marketing, pollution of environment, and the quality of consuming life. Third, this study found that computer networks, aiming at collecting and analyzing the very useful to improve the consuming life of Japanese by providing sufficient consumer information to encourge rational choices of consumers. Forth, a close cooperation between the central and local administrations was crucial for the successful outcome In Japan This paper gives us useful guideline regarding how to improve consumer movement and govemments' policies for protecting consumer in Korea. In addition, other lessons on successful consumer satisfaction policies of Japanese firms may enable Korean firms to shape effective consumer policies of enhancing their competitiveness.

  • The paper reviews the movement in the United States to supplement environmental regulations with volunteer programs that encourage institutions and industry to go beyond compliance to achieve greater reductions in their waste and emissions than might otherwise be accomplished through the exclusive reliance on increasingly rigorous "end of the pipe" regulations. These volunteer programs have as a common element the encouragement of "pollution prevention" as a preferable strategy. Pollution prevention is a term used in the US to describe strategies, technologies, policies, etc. that focus on eliminating waste and emissions at the source rather than just treating and controlling them. In some countries the term "Clean Technologies" is used rather than pollution prevention. In the paper the author reviews selected voluntary programs and reports on accomplishments to date for those programs.

  • Food intake and swallowing are complicated and intriguing series of movements involving voluntary and involuntary activities of cranial and spinal nerves and muscles. They have two most important functions, that is, food passage from the oral cavity to stomach and airway protection. Tongue, buccinators, and hyoid bone and its muscular attachments are anatomic structures for swallowing of special interests. The swallowing process of liquid is commonly divided into oral preparatory, oral propulsive, pharyngeal, and esophageal stages according to the location of the bolus. The movement of the food in the oral cavity and to the oropharynx differs between eating solid food and drinking liquid.

  • The career development of information security workforce affiliated in administrative department is very different from workforce affiliated in private companies. Their career development attempts are made not by voluntary motivation but by involuntary job movement by the principle of internal relocation. So they are not directly linked to monetary compensation or advancement. Due to the nature of the organization, their work attitude is very passive and there is little intention to turnover. They do not need professionalism, but they must be retrained according to the law. In this paper, we investigate and analyze the roles and responsibilities of information security workforce of each administrative department. And we do questionnaire survey to find out current roles and responsibilities of them will not affect the demand for retraining. Through these research, we would like to discuss how to manage information security workforce affiliated in administrative departments.

  • The main purpose of this study is to develop and apply a means of connecting reading movement and Newspaper In Education (NIE) activities utilizing the voluntary participation and cooperation of local school districts and autonomous government entities. This is necessary to revitalize or systematize the environmental social life of reading newspapers and NIE activity. Literary or inquiry research will be initiated in this study in order to quantify the current or actual conditions of this connection, delineating the basic objectives of this study, and determining the developmental directions for continuing this study as related to the connection of reading movement and NIE activity. Anticipated study activities or major tasks are as follows. First, develop a variety of intended programs and learning materials necessary for each. Secondly, develop and establish corresponding online data and educational programs. Thirdly, a "cooperation" system must be established and training programs implemented reinforcing these ideas. And, lastly (and to gain wider acceptance), starting a public relations campaign to show or illustrate the benefits of this study and these intended research activities. In conclusion, if a connection between reading movement and NIE activity are fully established and periodically adjusted by means of continuing discussions on the merits or concerns based on the study findings, the full potential of the reading movement connection with NIE activity will be realized and achieved to its truest meaning and/or highest order.
