The pulse tube cooler as an alternative of Stirling, G-M or VM cooler to overcome the requirement from the various application fields is described. The necessity of the object oriented cooler development is explained to realize the cryocooler of more energy-efficient, more reliable, more compact and less expensive than what is currently available commercially.

Background: Radiation accidents having occurred in recent containing the accident in Fukushima nuclear power plants of Japan were resulted to the increase in some public concern, anxiety and confusion for radiation or nuclear safety. The public anxiety for radiation is not being decreased though the announcements done in radiation research institutes in Korea. Therefore, this study aims at providing an effective system for radiation publicity to the public members by the clipping analysis for the radiation articles reported in the media. And, the relation between those radiation issues and the radiation perception to the public members is analyzed. Materials and Methods: The radiation articles reported by them in 2013 and 2014 have been collected, and they are then classified with the article characteristic, field and tendency. Classified articles have been reviewed by dividing as two year. The 210 articles have been compared for their tendencies, characteristics and fields by year reported, and their characteristic comparison by reported year are then reviewed. Results and Discussion: Though the frequency that the radiological accidents have occurred in worldwide is far low compared to the accidental frequencies occurred in the general industrial fields, the radiation perception is being still deteriorated because of its special problem, which is defined as exposure, contamination or radioactivity, about radiation. The basic principles for radiation communication were suggested for preventing some unnecessary misunderstanding due to the variation of understanding for radiation issues. Conclusion: It is necessary to perform a variety of strategies for the publicity in improving the radiation perception, to build a relationship with the press or the media and then to consistently interact with them. Radiation communication must be performed by radiation experts or complete charge department, and must be consistently performed and be taken predictable patterns.

Construction industry try to use weather information because construction is much influenced by weather conditions. However, the researches, how to use the weather information in construction fields at present state, are not sufficient. Therefore, the purpose of this study is to present the methods for improving weather information application by analysis the present state in building construction fields. The results show that educations about application of weather information are poorly conducted though the construction engineers know that weather information is helpful to improve the performance and that weather information serviced is not suitable to apply their field's work. Based on the results, for improving the application of weather information, the construction engineers are structurally educated about applying weather information and the weather information system is developed to specialize the building construction projects. Additionally, construction companies have a long term plan to cultivate the experts who equally have a good knowledge and experience of weather information and construction technologies. These proposed methods help to decrease the influence of weather conditions and finally to improve the performance in building construction projects.

Radio Frequency Identification(RFID) technology has been widely used to identify and keep track of physical objects. The EPC Network Architecture, which is proposed by EPCglobal to promote EPC and RFID technologies, consists of several layers to deal with the captured data. Many studies concentrated on dealing with RFID tag data (ECReports) from ALE. However, there is no well-known work on specifying how to generate high level EPCIS events. For the incoming ECReports, Capturing Application cannot decide to generate which event types and how to get the semantic fields. In this paper, we propose the new Capturing Application (NCA) to solve the problem. NCA can generate EPCIS events correctly and automatically.

Recently, the postal service encounters the various changes in the overall mail environment including the reduction of letter volume, keen competition of the private parcel service and EMS, diversification of customers' demand and etc. In this environment, Korea Post is considering new concept of postal service in order to provide the mail service based on informatization and automation to a client and secures the predominance in competition. We analyze the current environment of postal service for applying the gCRM (Geographic Customer Relationship Management). We propose some possible application fields and present an efficient phased application plan for each field.

Ministry of Science & Technology (MOST) and Korea Aerospace Research Institute (KARI) are preparing for the first Korean astronaut program based on the mid and long-term basic plan for space development of Korea from the year of 2003. KARI is making plans for the Korean astronaut's missions with Russia. To participate in the International Space Station (ISS) utilization through the Korean astronaut program, KARI investigates a lot of manned space missions. Among the suggested items, Earth observation on the Russian Module of ISS is the one expected mission for a Korean astronaut. This paper is intended to give readers a brief introduction of ISS Russian Module and research fields of Earth observation for astronaut's mission.

The International Space Station (ISS) offers research opportunities to researchers through crew's space mission in the field of remote sensing. ISS provides the facilities to place and operate experiment equipments in a variety of fields, especially, microgravity experiments and Earth observations. This paper is intended to give readers a brief introduction to the ISS utilization and the capabilities for remote sensing researches. We investigate what kind of crew missions and payloads should be developed for remote sensing researches on the ISS.

The electrolytic water(EW) has been used in agriculture, medical, semiconductor, and household fields. However there has been no use of EW in the textile process so far, because the application in the textile industry has been needed a large amount of EW in real process conditions. Recently, we have got electrolytic oxidation water(EOW) and electrolytic reduction water(ERW) by development of a electricity electron technology. And, the productivity of EW manufacture apparatus is arrived to large capacity. As a result, the application of EW could be possible in the textile industry. In this study, to confirm the possibility of application of EW, we scoured and hydrolyzed PET fabric using the EW. It was possible that the application of ERW for the scouring and hydrolysis of PET fabrics in the textile process.
