In this paper, we propose a integrated real-time monitoring system for recycling agriculture resourcing based on USN. We design and implement the monitoring system so that we can integrate the quality control of farmyard and liquid manures, barn environment monitoring, and positioning information control into a total management system performing recycling of excrement and manure. Selection of sensors and sensor-node construction and requirements, structure of wire/wireless communication networks, and design of monitoring program are also presented. As a result of operating our system, we can get over various drawbacks of conventional separated system and promote the proper circulation of excrement up to the farmyard. We confirm that these advanced effects arise from the effective management of the total system integrating quality control of farmyard/liquid manure, barn/farmhouse information, and vehicle moving monitoring information etc. Moreover, this monitoring system is able to exchange real-time information throughout communication networks so that we can construct a convenient information environment for agricultural community by converging IT technology with farm and stockbreeding industries. Finally we present some results of processing using our monitoring system. Sensing data and their graphs are processed in real-time, positioning information on the v-world map offers various moving paths of vehicles, and statistical analysis shows all the procedure from excrement occurrence to recycling and resourcing.

Biogas is a gaseous mixture produced from microbial digestion of organic materials in the absence of oxygen. Raw biogas, depending upon organic materials, digestion time and process conditions, contains about 45-75% methane, 30-50% carbon dioxide, 0.3% of hydrogen sulfide gas and fraction of water vapor. To achieve the standard composition of the biogas the treatment techniques like absorption or membrane separation was performed for the resourcing of biogas. In this paper the experimental results of the methane purification in simulated biogas mixture consisted of methane, carbon dioxide and hydrogen sulfide were presented. The composite membrane is manufactured within polysulfone in order to increase the separation performances for the gaseous mixtures of $CO_2$ and $CH_4$ which are main components of the biogas. The effects of feed pressures and mixed gas on the separation of $CO_2-CH_4$ by membrane are investigated. Chelate chemical was utilized to treat the purification of methane from the $H_2S$ concentration of 0.3%.

The model-free control of aeroelastic vibrations of a non-linear 2-D wing-flap system operating in supersonic flight speed regimes is discussed in this paper. A novel continuous robust controller design yields asymptotically stable vibration suppression in both the pitching and plunging degrees of freedom using the flap deflection as a control input. The controller also ensures that all system states remain bounded at all times during closed-loop operation. A Lyapunov method is used to obtain the global asymptotic stability result. The unsteady aerodynamic load is considered by resourcing to the non-linear Piston Theory Aerodynamics (PTA) modified to account for the effect of the flap deflection. Simulation results demonstrate the performance of the robust control strategy in suppressing dynamic aeroelastic instabilities, such as non-linear flutter and limit cycle oscillations.

This paper approaches the issue of seismic vulnerability assessment strategies for facade walls of traditional masonry buildings through the development of a methodology and its subsequent application to over 600 building facades from the old building stock of the historic city centre of Coimbra. Using the post-earthquake damage assessment of masonry buildings in L'Aquila, Italy, an analytical function was developed and calibrated to estimate the mean damage grade for masonry facade walls. Having defined the vulnerability function for facade walls, damage scenarios were calculated and subsequently used in the development of an emergency planning tool and in the elaboration of an access route proposal for the case study of the historic city centre of Coimbra. Finally, the methodology was pre-validated through the comparison of a set of results obtained from its application and also resourcing to a widely accepted mechanical method on the description of the out-of-plane behaviour of facade walls.

The number of foreign cabin crews consist of 7% of total crews in K-airline, of which Chinese crews are of 38%. The number of foreign crews are 433 from 10 countries as of the end of July 2012. The airline has continued to hire foreign cabin crews to increase efficiency of human resourcing qualified flight attendants. This paper tried to do empirical research through SEM(Structural Equation Model) to overview confirmatory factors and course effects integrally. Cultural stress, aggressive coping, social support and job adaption have been chosen to be a factors. Especially, the SEM was set to show indirect effects of cultural stress and aggressive coping through social support to the dependant variable, job adaptation. According to the analysis result, cultural stress has a direct negative effect on job adaptation. Aggressive coping has also a direct positive effect on job adaptation. It has also proven cultural stress and aggressive coping has a indirect effect to job adaptation through social support. This paper is expect to contribute to develop such training and administrative programs as enhancing foreign crews' job adaptability and managing them effectively.

This study aims to assess the traditional knowledge on seasonal customs and its characteristics for practical use. The Delphi method and correspondence analysis were hired to collect and analysis the data. Twenty six professionals for the Delphi participated in three-round process. The followings were concluded. The number of items valuing and resourcing for seasonal customs. were 118(40 for folks and ceremonies, 53 for foods. 25 for plays) on Delphi results. For example are Bokjori, Dano fm, Bokjumeoni, Chuseok, Tano festival, New Year Card, washing hair with an iris, Soup with rice cake, Boiled rice with five cereals, Rice and red-bean porridge, Kimchi-making for the winter, Sharing walnut with friends, Game of yut, Playing kite, Play with Hanga etc. Nowadays the ideas of modernized practical use on seasonal customs was to connect with modernized scientific technology and designate commemoration day. The items for connecting with modernized scientific technology were new year card, painting and recording sound with traditional seasonal customs, food areas, cake with seven kind of cereals, play areas, hand wrestling, cockfighting in folks and customs areas. Also the items for designating commemoration days were the Suelbeam and Suelbeam Socks present for the aged people, man cooking day, Korean traditional workers day in folk and ceremony areas.

This study is designed to find out the protection system of intangible cultural property as the current national policy and analyze the foundational problems in order to suggest the future vision in a way of transmitting the traditional cultural heritage to the descendants, based on the policy support for the intangible cultural property under the control of Commission for Ibuk 5-do (5 Northern Provinces of Korean peninsula). The research issue is first, the aging of the holders of the important cultural properties in Ibuk 5-do and the overcoming of the incomplete transmission system. The second issue is the protective policy of the transmission from the national perspective and the justification of the government's financial support. The third issue is the development of cultural contents by using the intangible cultural properties in Ibuk 5-do and the suggestion of the creative development for the resourcing of culture. As for the research methods, reference research and analysis on interview data and data from the related entities was done were analyzed and the results were actively adopted. The research results showed the followings to be required; first, the aged holders of the cultural properties shall be treated well and at the same time, the holders recognized to hold the transmission ability shall be dually designated. Second, the training system for the younger generation to keep the traditional cultural heritage shall be established; Third, the educational program and school education shall be extended so that the importance of the transmission of the intangible traditional cultural properties in Ibuk 5-do (northern 5 provinces of Korea) shall be recognized; Fourth, the recording system shall be constructed and its application system shall be required. In the end, in order for such development methods to be implemented effectively, active government support is desperately required.
