This study assumes alternative character of the operation of mathematical club in middle school. The case that operated the voluntary mathematics club for one year was analyzed and the educational effect was considered. First, the examination instrument for choosing the members of mathematics club was developed and used. And, diverse teaching and learning materials for improving creativity and mathematical ability of the members were used. Second, the difference of learning result between the experiment group and control one who joined the activities of mathematics club was analyzed. Finally, mathematical club activity based on mathematics history appeared to be effective in improving academic achievement and mathematics exploration activity.

Objective : This Study aims to survey the current situation of the 'Future Leaders of Korean Medicine' curriculum and thereby improve the quality of the curriculum. Methods : 10 students in the curriculum answered 3 items of the NSSE questionnaires; 'Active and Collaborative Learning', 'Student-Faculty Interaction', 'Satisfaction'. Results : 'Worked with other students on projects', 'Tutored or taught other students (paid or voluntary)' average frequencies are relatively low in the 'Active and Collaborative Learning' item. 'Worked with faculty members on activities other than course-work' average frequency is relatively low in the 'Student-Faculty Interaction' item. Conclusions : The curriculum should be improved to encourage the students to take the leading roles at Collaborative Learning and to interact with the advisors.

A Many studies have been made on the prediction of human voluntary movement intention in real-time based on invasive or non-invasive methods to help severely motor-disabled persons by offering some abilities of motor controls and communications. In the present study, we have developed an internet game driven by and/or linked to a brain-computer interface (BCI) system. Activities of two single neuronal units recorded from either hippocampus or prefrontal cortex of SD rats were used in real time to control two-dimensional movements of a robot, or a game object.

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.

Commercially available software packages permit to position human models of various geometries in practical scenarios while respecting the anatomical constraints of the skeletal joints and of the bulk of the bodies. Beyond such features, the PAM-Comfort(sup)TM software has been conceived to provide direct access to the muscular forces needed by humans to perform physical actions where muscle force is required. The PAM-Comfort(sup)TM human models are made of multi-body linked anatomical skeletons, equipped with finite elements of the relevant skeletal muscles. The hyper-static problem of determination of muscle forces is solved by optimisation technique. Voluntary stiffening of muscles can be added to the basic contraction levels needed to perform a specific task. The calculated muscle forces obey Hills model. The model and software have been applied in several interesting scenarios of various fields of application, such as car industry, handling of equipment and sports activities.

The purpose of this research is to invent the method which improve the problem - solution power in mathematics, making learning materials for it and apply it to the inactive 1st grade high school students. The results of this reaserch are as follows. 1. Through this 4 phased team teaching, the atmosphere of learning is positive and learning activities are voluntary and the attitude to the mathematics is improved. 2. The harmony of team studying for a problem solution, problem understanding, flowchart drawing and mind map studying enabled students to have confidence of learning, leading to improve the ability of mathematics.

Objectives: This paper aims at addressing the importance of community-based health promotion. It would identify the origin of community health programs in Korea, which emphasized community involvement. And it would reveal the discontinuity of community-oriented health programs in the current health promotion activities. Finally, the methods of attaining community-based health promotion would be suggested. Results and Conclusion: Community-based health promotion had been implemented in rural areas by medical schools in the 1970s and 1980s, which emphasized the role of village health workers. But their roles has disappeared since the government-initiated health promotion policies and programs have been implemented in the mid-1990s. This paper addressed the factors contributing to this discontinuity, such as the expansion of heath insurance system, the change of health care discourses, the monopoly of resources for health promotion by government, and the bureaucratic approach to health promotion, etc. This paper suggested the utilization of voluntary and civic organizations in community for realizing the goal of community-based health promotion.

For human factor engineering and wearable robot design, the quantitative assessment of physical workload is needed. Through measuring the surface EMG (sEMG) and analysis, the physical workload in overhead lifting posture is presented in quantitative manner. By normalizing sEMG activities with maximal voluntary contraction (MVC), the inter-subject variability is reduced. In all muscles, %MVC increased as the weight of lifting object increases. In anterior deltoid muscle, the %MVC was 3-4 times higher than the other muscles which imply that this muscle performs the major role in the overhead lifting posture. In fatigue analysis, %MVC and the mean frequency in muscle of anterior deltoid changed markedly when compared with other muscles. Through the suggested procedures and analysis, the physical workload for a specific posture can be represented in quantitative way but the clinical meaning for the value should be investigated further.

Purpose : The purpose of this study is to help understanding nursing application of morale after analysing the concept of morale. Method : With a various investigation of the records on the morale, I identified the characteristics of morale. Result : The characteristics of morale are as follows; 1) The active and voluntary motives of performing in a job. 2) The group phenomena as well as individual ones. 3) The characteristics and changeability according to the situation. 4) The self-esteem and satisfaction in a job. Conclusion : As morale can affect the management and success of organization constantly, the analysis of the concept of morale will be available in nursing administration, so the nursing managers should be interested in morale, And nursing managers should enhance the staff's morale in order that the staffs are willing to participate in their work, to be faithful in an organization, to develop creativity and to do better activities and so they have to contribute to the development of the organization and its members.

Low back pain has been known as the most frequent musuculoskeletal disorders in modern industrial society and cost by low back pain is increasing mon and more. The asymmetric lifting has been identified as a major risk factor of low back pain. In this study, the muscle activity and muscle exertion level during asymmetric load handling (without trunk flexion) was estimated. The results of normalized MVC measurement were decreased about 16％, 24％, 34％ respectively as the asymmetric angle was $30^{\circ}$, $60^{\circ}$, $90^{\circ}$. From the results of EMG measurement contralateral muscles were more active than ipsilateral muscles. RMSEMG values of right erector spinae muscles were decreased as the work posture went to 90$^{\circ}$ and those of left erector spinae muscles were increased until the asymmetric angle was 40$^{\circ}$ but decreased continually over 40$^{\circ}$. And for seven of subjects, activities of left and right latissimus dorsi muscles were maintained constantly, while for remainer, those were irregular.
