  • This study was to identify and quantify the flavor compounds in cream cheese and cholesterol-removed cream cheese made from whole milk powder stored at $7^{\circ}C$ for 4 wk. Flavor compounds of cream cheese were identified using gas chromatography mass spectroscopy and quantified by gas chromatography. The tentatively identified flavor compounds were mainly eight from fatty acids in cream cheese made from whole milk powder (CCWMP) and nine from fatty acids in cholesterol-removed cream cheese made from whole milk powder (CRCCWMP). In quantitative analysis of the flavor compounds, most of the volatile compounds were slightly increased during storage. N-Decanoic acid was produced only in CCWMP. On the basis of the results, it was concluded that the quality and quantity of flavor compounds in CCWMP and CRCCWMP have almost no adverse effects in comparison with that of whole milk-made cream cheese.

  • For the improvement of the performance and life time of phosphoric acid fuel cell, the management of electrolyte in the electrocatalyst layer and electrolyte matrix in the cell structure is very important. Porous bipolar pinto structure, that is known as an advanced type, is generally used for the storage of electrolyte in the cell. In this paper, the single cell was made of the electrode by coating directly electrocatalyst layer on porous bipolar plate. The single cell showed $186\;mA/cm^2$ at 0.6V. This performance is similar to the performance of the conventional nonporous plate single cell. The technology of porous plate single cell could be directly used to the fabrication of stack in order to improve the performance and life time of phosphoric acid fuel cell.

  • Many countries are managing the transportation of hazardous materials under the specific provisions especially, as well as use, storage and management, because of their high risks. For the purpose of the revision of rail safety law for the safe transportation of hazardous materials, amount and kind of hazardous materials transported by rail in Korea are analysed and the standards of classification of hazardous materials are compared in domestic and abroad. There are lots of benefits for national rail safety law to implement an international law because our country's geographic location is convenient to connect the continent and to across the border. It is suggested that implementing a classification and test methods of hazardous materials enable to use internationally for the preparation of rail transportation to be increased.

  • Most conventional hybrid systems using renewable energy sources have been applied for stand-alone operation, but Utility-interface may be an useful and viable option for hybrid systems. Grid-connected operation may have benefits such as reduced losses in power system distribution, utility support in demand side management, and peak load shaving. This paper addresses power control and dynamic performance of a grid-connected PV/wind/BESS hybrid system. At all times the PV way and the wind turbine are individually controlled to generate the maximum energy from given weather conditions. The battery energy storage system (BESS) charges or discharges the battery depending on energy gap between grid invertger generation and production from the PV and wind system. The BESS should be also controlled without too frequently repeated shifts in operation mode, charging or discharging. The grid inverter regulates the generated power injection into the grid. Different control schemes of the grid inverter are presented for different operation modes, which include normal operation, power dispatching, and power smoothing. Simulation results demonstrate that the effectiveness of the proposed power control schemes for the grid-interactive hybrid system.

  • The environmental conditions in smallholder dairy farms especially the effects of dairy wastes on waters and soil were the main objectives of this investigation. Forty-three dairy farms from an older dairy cooperative (Nongpho Dairy Cooperative, NP) were compared with four dairy fauns from relatively new dairy cooperative (Kamphaengsaen Dairy Cooperative, KS) for the quality parameters of water and soil samples during a 12-month period. Forty-three farms at NP were from three geographical areas and three levels farm crowdedness. The results from this study clearly showed that the waste waters from older dairy barns contained much higher levels of organic and inorganic substances which could create environmental pollution if not properly managed. The differences in waste water qualities due to areas and seasons were not significant, while waste water samples from crowded farms tended to contain higher averages of waste water parameters such as COD and BOD. Highly significant correlations between pairs of waste water parameters indicated that certain parameters can be used without the need for chemical analysis of some other parameters. The qualities of well water on dairy farms as well as water samples from public waterways nearby indicated some contamination of dairy wastes such as manure. Storage and sun-drying of dairy manure on bare soil surface could result in the contamination of underground water and nearby water sources. Some recommendations from this study if implemented can prevent environmental pollution in smallholder dairy farms.

  • Digital Multimedia Broadcasting (DMB) is the mobile TV service based on a digital radio transmission system that provides high quality audio/video and other auxiliary data services. As users want to store the DMB content in their device to be consumed later or to be shared among users, a standardized format needs to be specified to guarantee the interoperability for the DMB contents for various devices. DMB AF (Application Format) specification defines a file format for DMB contents and services. It specifies how to combine the variety of DMB contents with associated information for a presentation in a well-defined format that facilitates storage, interchange, management, editing, and presentation of the DMB contents in protected, governed, and interoperable ways. In this paper we present our implementation of DMB AF as part of the development of DMB AF reference software. Our implementation of DMB AF is developed as the reference software for the standard specification that consists of a three applications: packager, media player, metadata browser and collection of supporting libraries used by the applications.

  • USN-based real-time monitoring systems, which receive raw data from sensor nodes and store the processed information in traditional servers, recently get to be replaced by IoT(Internet of Things)/WoT(Web of Things)-based ones. Especially, Social Web of Things(SWoT) paradigm can make use of cloud storage over Social Network Service(SNS) and enable the possibility of integrated access, management and sharing. This paper proposes an improved SWoT-based real-time monitoring system which makes up for weak points of existing systems, and implements monitoring service integrating a legacy sensor network and commercial SNS without requiring additional servers. Especially, the proposed system can reduce emergency propagation time by employing PUSH messages.
