Nowadays, fashion is high evaluated as a mean of self expression as well as a formative art itself, The moderns' elevated beauty sense and strong desire for individuality expression have not only advanced various and refined fashion presentation but also led to expansion of fashion to a total coordination covering hair and makeup. Of them, hair styling does play an important role in rounding out the various image of fashion. It is not only far from omittable part but also, out of simplicity in the past, taking formative characteristics in form and structure day by day. Especially, artistic elements of modern arts are being introduced as motives, and of which representative is e introduction of kinetic art which is thought the artistic approval on mechanization trend in the 20th century. Thus, the study was intended to investigate how and in what forms the various features of kinetic arts is reflected in the modern hair shaping, and to suggest a new prospect of kinetic art-applied hair shaping.

Ambient noise as a background noise in the ocean has been well known for its the various and irregular signal characteristics. Generally, these signals we treated as noise and they are analyzed through stochastical level if they don't include definite sinusoidal signals. This study is to see how ocean ambient noise can be analyzed by the chaotic analysis technique. The chaotic analysis is carried out with underwater ambient noise obtained in areas near the Korean Peninsula. The calculated physical parameters of time series signal are as follows: histogram, self-correlation coefficient, delay time, frequency spectrum, sonogram, return map, embedding dimension, correlation dimension, Lyapunov exponent, etc. We investigate the chaotic pattern of noises from these parameters. From the embedding dimensions of underwater noises, the assesment of underwater noise by chaotic analysis shows similar results if they don't include a definite sinusoidal signal. However, the values of Lyapunov exponent (divergence exponent) are smaller than that of random noise signal. As a result we confirm the possibility of classification of underwater noise using Lyapunov analysis.

The Korean National curriculum is divided into the curriculum, discretion, and extra curriculum activity. Extra curriculum among them consists of fie grounds, that is, a self-governing, adjusting, developing, service and exercise activity. The content of developing activity among them includes academic literary arts, in that the developing activity related to science. The developing activity connected with science can be a good chance which students can have deepened learning besides a regular course. In addition, effective management in science class can play an important role to cultivate scientific sense and to raise scientific talent. The study finds out how the management connected with science-related extra-curricula activity in science is actually going on. The study carries out a questionnaire with 40 teachers and interviews 5 teachers as well who are in charge of science-related extra-curricula activity connected with science. As a result, on the side of students, ① systematic introduction course in science is not given to them, ② the course is operating without considering students interests and levels, so it causes the problems of developing their potential ability and extension. On the side of teachers, ① they organize the science department based on school's situation and policy. ② they disregard teachers' roles and interests. ③ the science department's program is operating improvisedly rather than systematically, ④ the evaluation is done formally is found out. I have come to know that to manage a desirable science-related extra-curricula activity connected with science needs to have sufficient, detailed materials and experts from outside.

Communication skills, such as writing documents and presenting technical details, are thought to be essential for modern engineers. Engineering students usually have less interest in writing and presentation than their humanities student counterparts and their concerns are different, too. So it is necessary to teach them in a different way which is suited to them. However, teaching such subjects has been a tricky problem for educators in terms of teaching methods. Also, to teach writing and presentation effectively for engineering students, collaboration between the faculties of different disciplines is necessary because each discipline has its own specific domain knowledge and approaches. But many unsolved problems exist with regard to how to deal with the technical and administrative aspects, and so on. This paper introduces one case in the education of technical writing and presentation, which is a collaboration between an engineering faculty and a faculty of literature. The literature faculty conducts basic education and training for writing skills, while the engineering faculty teaches the technical aspects of documentation, as well as presentation skills. The focus is placed on topics such as self-introduction, searching technical literature and materials, describing and explaining things and presentation practice, etc. During the class there is cooperation in each topic domain, while the faculties collaborate in teaching and evaluation.

There is a wide variety of system and applications in the power system. However, they have compatibility issues because they use different data standard and communication method. With the introduction of the smart grid, power system has been grow and diversified. Therefore power system need to be compatible with each other and the interoperability between applications is increasingly important. Thus, the IEC established IEC61970 and CIM Standard data exchange model for interoperability and system integration. Server-Client system was constructed which using CIM HSDA(Part4), a standard communication model, presented in IEC 619710. Also, self-developed real-time voltage stability analysis application and contingency analysis application was used. CIM HSDA was used for data input and real-time analysis. Tolerance of result which is in the range of allowable derived by Perform real-time voltage stability and contingency analysis of Jeju power system, and then compare it's result with PSS/E result.

This is a research report about the method of how to maintain qualification of certification flight test crews. KCA(Korea Certification Agency) have completed the KC-100 airplane certification flight tests which is the first time experienced flight tests operation. After the certification flight test, it has been found that annual flying time requirement of 100 hours to the certification flight test pilot is too strict, and other several requirements to maintain the qualification of the certification test crew such as aircraft certification introduction training, initial flight test pilot and flight test engineer certification training, crew resource management training, aviation physiology training, and survival training was difficult to implement in Korean civil aviation environments. In this study, it was suggested that 30 hours of flying time for maintaining certification flight test pilot qualification could be applied to contribute for safe operation of certification flight test and the other training requirements of the certification flight test crew could be fulfilled using self made training courses, existing FAA training courses and Korean Air Force training resources. Therefore, it is recommended that the regulation of maintaining the certification flight test crew qualification should be refined to implement the requirement practically.

Recently the information system introduction and the application which use the computer are increasing. The efficient operation of information system helps corporations to improve productivity, customer service and corporate competitive power. SaaS(Software as a Service), which is the developed type of outsourcing in the area of information technology, is to use standardized and packaged application by hosting from the outside of enterprise. SaaS is not developed yet as much as people's interest about that in the initial stage, but its related technology and service capacity are accumulated after repeated trial and error, and it's ready to activate the industry. In the area of information system, studies on the measurement of service quality were followed. But there is little study on service quality measurement in the field of SaaS(Software as a Service). The purpose of this study was to divides the SaaS with e-SERVQUAL and it consider the relationship with the perceived recognition and the usage intention. According to this, variables of traditional research were rejected because SaaS is not developed yet in Korea. But information had a strong effect on perceived recognition. Therefore, business related with in SaaS must have provided a correct information about various applications.

Background: In 2013, legislation in Vietnam regulated smoking in public areas. Included was a ban on indoor smoking at universities. Objective: Since awareness and attitude are moderators of the effectiveness of smoke-free policy, ou aim was to assess changes in students' knowledge and attitude tosecond hand smoke (SHS) and awareness and support of smoke-free legislation at four Vietnamese universities, one year after legislative changes. Methods: A two-phase cross sectional study of undergraduate students using self-administered questionnaires (based on the Global Adult Tobacco Survey and the Thrasher survey) was conducted at the introduction of the legislation and one year thereafter. Results: One-year post legislation there were significant increases in knowledge of smoke-free legislation and awareness of universities as smoke-free environments. There was a significant increase in knowledge of harmful effects of SHS on diseases such as examples in the heart and lung, including lung cancer, and miscarriage. Students expressed strong support of smoke-free environments in universities, hospitals, schools, workplaces, public transport, libraries, cinemas and theatres; support was also increased post legislation. Changes were seen in attitude to SHS, and rights of non-smokers and smokers. Conclusions: Positive changes have occurred in knowledge and attitude toward smoke-free environments and SHS in universities since enactment of Vietnamese tobacco control legislation.
