Spandex fibers have superior stretch and elastic recovery ability. Composite yarns containing spandex are frequently used to manufacture elastic textile products and accessories. We have developed a composite yarn spinning system that produces different kinds of composite yarns containing spandex on a modified open-end rotor spinning frame. By changing the twisting parameter of composite yarns, we studied the structure and properties of rotor-spun composite yarns with spandex. The results indicate that the twisting parameter has great influence on the structure and properties of rotor-spun composite yarns with spandex. The linear density of spandex filament has influence on the properties of composite yarns too. In comparison with normal rotor-spun yarn, the appearance of composite yarns is clearer, the structure is much tighter, and the properties are improved.

STEAM education is a topic-based curriculum to integrate the concepts into other subjects such as science, technology, engineering, art and mathematics in order to improve the students' interesting, understanding, integrated thinking and problem solving ability. In this paper, we designed STEAM curriculum in the form of Project-based Learning and developed the material for elementary students. We also developed the android-based application through searching for a utilization of IT simulation for enhancement the students' Project-based Learning effect.

Purpose: The concept of sensibility as sensitive perception is a part of the most important elements in human relations and nursing. However, sensibility has not been a focus of nursing research and it seems important to clarify the meaning of sensibility. Therefore, in this study the meaning of sensibility as a cognitive faculty of humans was explored. The results will contribute to the development of nursing science and art. Method: The process described by Walker and Avant to analyze concepts was used to define the concept of sensibility. Results: Attributes of sensibility were defined as 'emotional ability to feel', 'delicate, sensitive awareness of emotion' 'appreciative, tender hearted about oneself and others', 'awareness of intellectual, moral values', 'liability to be vulnerable', 'direct interrelation with individual'. Conclusion: The sensibility mentioned above included the attribute of caring within nurses intrinsic disposition which is achieved through the process of interrelational communication. Therefore continuous study and development of this concept should not only provide resources for nursing but also have a positive effect in therapeutic personal relationships.

Primary prevention of low back injury in industry has focused on assessing the person's ability to perform physical labor. If the job to be performed is known to require lifting and moving of materials which could stress the low back, then special consideration is given to the health and functional capability of the person, s back. The major pursuit in lifting task of research is to provide objective criteria based upon all of the relevant mechanical parameters which describe both man art task so as to minimize the probabilities of injury within the economic constraints of each organization. The purpose of this study is to predict the back compression of persons asked to lift objects while assuming different position by computer simulation. The primary result of this study is that the incidence of low back injury is correlated with higher lifting strenth requirements as determined by assessment of both the location and magnitude of the load lifted. It is, therefore, recommended that load lifting be considered potentially hazardous, and the action limit and the maximum permissiable limit be used to guide corrective action.

Indoor of 21th century information-oriented society is feeling necessity of emotional design that can satisfy emotional of human. Desire of modern becomes various and emotional lighting design is risen on important element in indoor plan on human oriented modern society who become complicated. Emotional space is trend that is atomized as go today and is expanded as the target and area also go. That is, is included as target of emotional space to light and sound, taste, smack and is appealing by senses of human. Wish to do color that is optical element among element of senses differently and present design. Design concept of this research is emotional lighting design that can receive. It is lighting that equip emotional beauty and ability from modern indoor improving space. I wish to quote emotional lighting design about effect gotten to indoor by sight of designer.

The rapidly improving price-performance of wireless technologies is providing an unprecedented platform for the development of wireless applications for the business. Such applications are able to take advantage of a new paradigm of mobility for data services, with the ability to sensitize to location, time and personal features. While big business has been a central feature of wireless implementation, it is now clear that small- and medium-sized enterprises (SMEs) are beginning to take advantage of the strategic benefits of wireless data communications. This study examines the state-of-the-art of wireless data services in New Zealand. It provides a survey of 127 current applications in use, as well as two short illustrative cases of application use. The paper rounds off with a summary and conclusions.

The most remarkable and characteristic problem of design is that of creativity of design. Originality is a part of creativity. In the process of designing, we used to handle design thoughts that shows some patte군 of divergent and productive thoughts. During design thinking, for example 'Idea sketch', We also are under Pattern Recognition and Gestalt principles organization. In this study, it is reorganized that the 'Originality Test of Line Drawing(OTLD)'is a measurement system for personal originality. There is a regression on two tests of OTLD, which has 1 Semester Interval. From the regression data, Test2 = 7.763 + 0.643Test1, F value : 55.219, Prob : 0.0001. We would suggest a measurement system for an ability of originality in design fields, but we couldn't find any reliability and validity for Fine Art fields. In this point, OTLD could be a development tool for design creativity.

In the engineering students, MSC is the most important basic areas in education. Also, the calculus is a main subject in the MSC. So calculus has been operating the annual number of courses at the university. We introduced the concept of joint control ; the joint syllabus, test and assessment. In harsh conditions to maintain joint control system of the calculus, we built a computer-aided-system to manage web-based result processing system. In this paper, we discussed the necessity and effectiveness of joint control system for calculus.

The molten carbonate fuel cell(MCFC) has been under Intensive development for the last decade as a second generation fuel cell. The advantages of the MCFC over the phophoric acid fuel cell are higher efficiency, its ability to accept CO and $H_2$ as a fuel, lower material costs, and high operating temperature making internal reforming possible. These features, along with low atmospheric emissions, will open up a significant market as an attractive means of developing highly efficient power plant. This article reviews a status of the MCFC research and development, a principle of the MCFC, and cell and stack technology including the status of electrodes, matrices and electrolytes. Several technical difficulties which must be resolved to be commercialized art mainly focused.

Protection martial arts are neither the ability to protect oneself nor the exercise to increase the personal record. Their aim is to protect clients for the sake of their safety, Therefore, it needs special training course distinguished form general martial arts. Those who perform the duty of protection should make efforts to master every skill capable of meeting any situations in which unforeseen accidents may occur. So the coaches of protection martial arts should teach their disciples basic techniques by stages according to each martial art. They also should teach them systematically how to deal with each accidental affair on the ground of protection method. With teaching the way to cope with a crisis coaches might make the disciples feel real by presenting the real situation of different events to which protection arts can be applicable. And a mock exercise with a careful plan and enough practices as well as a mental training to all evaluate the anxiety which might be shown on duty could be helpful for educating elite personnel who will perform the duty of protection completely.
