Pohang Wind Energy Research Center (PoWER-C) is developing a 3 MW Radial Flux Permanent Magnet (RFPM) Synchronous Generator for offshore Wind Energy Converter (WEC). The blade rotor rpm is 15.7 and the gear ratio is set to be 92.93. The nominal generator rpm at the rated load is about 1459. Baseline design with surface mounted PM magnets are completed. However, there is some concern about the excessive eddy current heating in the magnets. To alleviate this problem, another design with embedded magnet is going on. With embedded magnets, the generator length should be increased to compensate the increased flux leakage. But the field fluctuation in the magnets due to the slots are greatly reduced. This means less eddy currents and lower magnet operating temperature. In this report, engineering efforts for embedded rotor is presented.

This study deals with the overall meta-cognitive aspects of ATC-Pilot miscommunications pertinent to cognitive human errors based on the previous literature research which it has been focused on the issue of the global aviation English use in regard with aircraft accident and incident. Especially, it addresses the concern over the ICAO aviation English language proficiency evaluation program which will be implemented globally in March, 2008. In addition, It presents the analysis related to the on-going English language proficiency level four test conducted for Korean civil airlines pilots and air traffic controllers.

Recently, as the multimedia processing application increases rapidly by going on increasing multimedia data, the efficient retrieval method of image information is required in many fields of application and becoming the matter of major concern. Furthermore, in the last few years rapid improvements in hardware technology have made it possible to process, store and retrieve huge amounts of data in a multimedia format. As a result, Content-Based Image Retrieval (CBIR) has been receiving widespread interest during the last decade. This paper propose the content-based retrieval system as a method for performing image retrieval through the effective feature analysis of the object of significant meaning by using YCbCr channel merging on the basis of the characteristics of man's visual system.

The environmental pollution by noise is recognized by the pollution source made it not only to carry out harm of the Quality of a life of people seriously in most countries, but was generated for most actual problems. The measure to such environmental noise must conduct first investigation which noise generating currently regarded as questionable says in what grade has resulted and the suitable measure by that is studied. The concern of the residents who demand such a comfortable living environment is increasing rapidly. Therefore, the three areas of Jeollabuk-Do judged that noise is comparatively severe was selected. It is going to grasp delicately the noise actual condition of a residential, semi-residential, commercial, industrial area.

Construction managers use scheduling methods to improve the outcome of their project. Despite the many obvious advantages of the critical path method (CPM), its use in construction has been limited. Understanding the reasons why CPM is not used as extensively as expected could improve its level of acceptance in the construction industry. The link between construction scheduling methods and the tasks expected to be performed by schedulers has been an on-going concern in the construction industry. This study proposes a task-technology fit model to understand why CPM is not used as extensively as expected in construction scheduling. A task-technology fit model that aims to measure the extent to which a construction scheduling method functionally matches the tasks expected to be performed by the scheduling staff. The model that is proposed is an answer to the lack of proper instruments for evaluating the extent to which scheduling methods are used in the industry.

In spite of the many obvious advantages of the critical path method (CPM), its use in construction has been limited. Understanding the reasons why CPM is not used as extensively as expected could improve its level of acceptance in the construction industry. The link between construction scheduling methods and the capabilities of the scheduling staff has been an on-going concern in the construction industry. This study proposes a staffing-technology fit model to understand why CPM is not used as extensively as expected in construction scheduling. A staffing-technology fit model that aims to measure the extent to which a construction scheduling method matches the staff's experience, know-how and capabilities. The model that is proposed is an answer to the lack of proper instruments for evaluating the extent to which scheduling methods are used in the industry.

At the beginning of 21st Century, human desire of communication is forwarding to the Cosmos The way of Communication is going to be not by simple methodology but by the complicated methodology with high technology. It will not be monologue communication but be interactive communication, that will make intelligence Infra, which could be able to communicate from the location of information is present to which is not present; and the multi-media which will be able to solve the technical problems of these communication; will be developed continually. In the genre of plastic art, there are no exception in these changedness. More developed and proceed to develope intermedia could be able of intercommunication. The more development of technology could be able to the more development of new plastic art. Furthermore the development of science make the genre of art to be changed. There are no exception of this changedness in any part of society, The art always has been guided by the person who has proceeding idea for new value. The 21st century plastic art will be in the procedure of the intercommunication. Human-being's concern is to communicate with Universe, and that will be multi-dimension$(4{\cdot}5{\cdot}6{\cdot}7{\cdots}dimension)$ communication beyond our usual recognition. To conjoin this, the possibility of cyber space expressing is going to be considered, and the way is being done by the development of the Media Art, which is able to go and back to the cyber-space. And the message will be so complicate beyond our recognition. Because we will need to communicate with various newly-built vocabulary, so we need to magnify the repertories of new vocabulary.

Purpose : The purpose of this study was to investigate whether or not the effects of the relationship among college students on the oral health were affected by the increased interest in the appearance. Methods : After explanation of this study, we conducted the questionnaire to those who accepted questionnaire from April 26 to May 28, 2017. In order to collect the data, Naver-form (mobile) questionnaire was distributed to the research subjects and the collected data. The analysis technique used the frequency and percentage to examine the general characteristics of the subjects and the status of the relationship. Chi-square test was used to examine the number of toothbrushes, toothbrushing time, oral health concern, regular oral examination and scaling, use of oral care products, smoking status, and bad breath. Result : Among the total of 190 research subjects, 79 (41.6 %) were male and 111 (58.4 %) were female. The presence of brushing just before going out and carrying a toothbrush were more frequent for those subjects who are in relationship (p<.001). The subjects who considered oral hygiene to be important were higher in those who were in relationship (p<.001). Conclusion : Some oral health care behaviors such as toothbrushing just before going out or carrying a toothbrush were well formed, and oral hygiene was important in those who were in relationship.
